Chapter 54 Automotive Industry

Experts from the automobile research and development department fiddled with the computer on the wall a few times, and the big screen on the wall displayed the outline drawings of various cars. They chose a car at random and said to Wang Zhen, "This is our car." The self-designed several cars have already been finalized, you can take a look at the design drawings of several cars, and you can design the production line only after you make a decision."

Wang Zhen carefully examined the drawings of each type of car.From plug-ins, to various chassis and suspensions, to the circuit design of the car.After looking at various design drawings, Wang Zhen asked: "Why are they all mid-range cars? Didn't we design low-end ones? Our products are only withdrawn. We must start with the masses and launch mid-range and high-end cars directly. It’s hard to capture the market.”

The engineer opened another file and said: "Here, it is designed according to low-end private cars and taxis. The shape has been improved by aerodynamic experts to better reduce forward resistance. The circuit part has been passed In order to simplify, two lines were designed. One is equipped with self-controlled optical brain and satellite positioning system, and the other is designed for reference, the middle and low-end cars on the market now, without optical brain and satellite positioning system. .”

Wang Zhen looked at the drawings carefully, hoping to find out the unreasonable places in advance, so as not to cause problems after the products were introduced to the market, which would affect the reputation of his company.However, soon, Wang Zhen realized that this was futile. Many of the experts he recruited this time were retired experts who had participated in the design of domestic cars during the liberation period.They have a better understanding of the principles of the car. They were limited to technical issues before and have not made better products.

This time, with the help of experts in aerodynamics, mechanical engineering, and materials science, as well as experts in electronic circuit design, they carefully studied all the materials left by Wang Zhen.After many discussions, I finally established my own model, and redesigned and revised every place that may have problems and defects, and then worked out the final design drawings.

Low-end cars include two types of taxis. They are high-end taxis equipped with satellite positioning systems, internal theater systems, and electronically controlled doors, and ordinary taxis that do not carry optical computers and satellite positioning systems.

Mid-range cars, including various private cars, commercial vehicles, etc., have a complete optical brain system, which can not only complete satellite positioning, but also have an advanced audio system inside, and can automatically judge car failures.

What Wang Zhen is looking at now is the design drawings of high-end cars. Although these high-end cars are not ready to be launched on the market for the time being, these experts are not slacking off.The aerodynamics experts compared the alien data modified by Wang Zhen, imitated foreign classic sports cars, and designed several classic business models with Chinese characteristics.

The spacious interior design and practical business functions made Wang Zhen have to admire the dedication of these experts.The interior of the whole car adopts infrared and wireless network methods to communicate with the notebooks brought by customers. On-board computers are designed on the backrests of each seat, which can be used for office processing, listening to music, and watching movies when needed. TV, or look up information on the Internet.

The whole vehicle is designed with new materials, which are light in weight, low in fuel consumption, and can be bulletproof. All types of bullets except armor-piercing bullets cannot effectively penetrate the car shell, and special composite materials are installed inside the car. The armor plate and glass are also specially designed bulletproof glass. Even if the blow can be accurately landed on the same point, it will take more than four shots to penetrate the glass.

The chassis adopts international leading technologies, and the whole vehicle adopts more than 100 patents, but Wang Zhen is still not satisfied.Although many patents of our own company have been adopted, there are still many other patents adopted in other parts. In the future, every time a car is sold, a large amount of patent royalties must be paid to foreign countries.

Sometimes, Wang Zhen would always think, shouldn't he be more adventurous and reveal more of the alien technology?But Wang Zhen didn't dare to take this risk. If someone betrayed him, it would not only cause him a lot of losses, but also bring him danger.Forget it, observe more in the future, there are reliable people, let's talk about it, when the time comes, I will use the cultivation method to tempt me, I believe, the temptation of immortality, not everyone can resist.

Although high-end cars, the addition of various materials makes the cost of the car much higher, which is not suitable for the market now, but Wang Zhen is very satisfied with the middle and low-end cars, and turned to the engine expert and asked: " All kinds of engines have come out with samples? Has there been any practical application?"

The car engine expert next to him said excitedly: "I have participated in the design of more than 40 kinds of car engines, none of which can be designed in such a short period of time, because many new technologies have been adopted. I had no idea. When the samples came out of the laboratory, we immediately modified some domestic cars and conducted actual inspections. There was basically no deviation between the performance and the calculations calculated by the optical brain. I really hope that we can see our own designs soon. engine, it travels all over the world."

Wang Zhen also knows that a product cannot always be in the laboratory. It must be put into practical application as soon as possible to detect specific performance and some design errors.Therefore, at present, the factory should be set up first and the production line design should be carried out.Turning to the design expert, he asked: "Well, it's time to get out of the laboratory and test the product samples. Have the drawings of the production line been designed? Have you figured out the cost?"

Wang Zhen took over the feasibility report from the automobile factory, and soon frowned.According to the data in the report, the cost of land, approval, etc. to set up a factory, together with the equipment required for the automobile engine manufacturing plant, automobile manufacturing plant, and production lines, will require hundreds of millions of funds. Moreover, the domestic equipment is basically very old. , Foreign equipment, if you have money, they may not necessarily sell it to you, and with the funds for various raw materials, your company will be emptied in one go.

"Mr. Wang, this is just the previous report. If you look at the back, there are several reports. The first report was formulated based on the use of advanced foreign production lines, and the latter reports were formulated using domestic equipment. The outdated domestic equipment will reduce the production capacity. Therefore, the various departments of our research institute met and decided to design the production line by ourselves.

This is a feasibility report of the production line designed by ourselves. For specific data, you have to go to the Design and Research Institute to ask. After the old expert finished speaking, he went to work on his own test. After listening to the old expert's opinion, Wang Zhen can be said to have trotted all the way out of the laboratory and came to the design and research institute.

Pushing open the door of the design room, you can see the Design Research Institute. The design drawings of the robotic arm are displayed on the large screen on the wall. Many people gather around the large screen to jointly study the areas that need improvement, and from time to time Yes, give orders to the operators behind.

After watching Wang Zhen for a long time, an expert discovered Wang Zhen, and said excitedly: "Mr. Wang, when did you come back? You came back just in time, because our state-owned production lines are relatively backward in technology and outdated in equipment, and the purchase of foreign advanced After all, the production line is troublesome and the price is ridiculously high, so we decided to adopt a self-designed production line.

We are planning to design a set of unattended production lines that rely on optical brain control. If we can succeed this time, we can renovate the CPU and motherboard production lines in the future, which can greatly improve the production progress, avoid improper human operation, and reduce the scrap rate. .

What you see now is that we have assembled experts from various departments such as laser positioning and robot research and development, referring to foreign advanced technology, as well as the experience of designing CPU and motherboard production lines in the past, and designing the robotic arm by ourselves.

Now the production line has been designed and undergoes final transformation.At that time, each cutting and cutting workshop will directly carry out stamping and forming after discharge, and welding by robotic arms. This is the same as the international advanced production line.

In order to make the production line adaptable to different models, we are now planning to change the original multiple welding into a multi-butt spot welding machine, which can be formed by one-time welding. For different models, as long as the welding hook assembly located at the head of the mechanical arm is replaced, the size of various welding parts can be changed.

This production line, as long as the raw materials are placed in a fixed position, it can automatically load materials, automatically cut, cut, and stamp. Now the welding part is being improved, because many positions cannot be operated by the mechanical arm. The original production line is all Relying on manual welding, we are going to change the original production process and assemble the production lines together for operation.

After the design is transformed, it is possible to completely input different data into the optical brain to change the welding parts of the robotic arm, as well as various actions and moving dimensions, to carry out the production of different models.

As expected, the production line should be able to be unattended and fully automated from feeding, cutting, stamping, to final welding, cleaning, and painting, with only intermediate quality inspection and final interior, instrumentation, audio, and vehicle. The assembly of computers, electrical appliances, etc. requires human operation. Moreover, the robot research group has developed a humanoid robot. At that time, it can directly use the robot to work and be controlled by the optical brain to further reduce production costs. "

This older generation of domestic experts who had participated in multiple processes of domestic automobile R&D, transformation, production, etc., looked at the company and designed the first internationally advanced domestic production line, chattering excitedly.After hearing his introduction, Wang Zhen sat in front of an idle optical computer, called up the design drawings of the production line, and looked at them carefully.

In the whole production line, the feed port is designed in the direction of the factory door. As long as the fed car is poured into the feed port of the production line, a mechanical arm will automatically unload the coiled car shell steel plate and put it into the cutting workshop. installed on the production line.

Wang Zhen called out the blueprint of the robotic arm, only to find that many high-definition, high-speed cameras were installed on it, and laser positioning technology was used to directly return the video signal to the control computer, and then the computer controlled the laser positioning system to accurately place the coils into rolls. The car shell steel plate is unloaded and put into the feed port of the production line.

The drawings to be divided in the next step are the parts in the workshop and the production line.The material is sent to the workshop by the conveyor belt, and the mechanical arm in the workshop inserts the fixed shaft fixed on the mechanical arm into the coil material, and then the fixed shaft will expand to block the coil material, and then the coil material, Put it into the cutting and cutting machine and fix it. If the material is used up, the video surveillance system and laser detection system in various places will return data to the optical computer. The optical computer controls the mechanical arm and will automatically repeat the loading action.As long as personnel are arranged to check regularly, the coil materials in each cutting workshop, the usage status, and the coil materials are sent to the feeding port in advance, and sent to the workshop by the mechanical arm, it is enough, and no redundant personnel are needed.

In the production workshop, the cutting and cutting machine fixedly stacks the cut plates at the discharge port. When the plates are reduced to a certain number in the production line, or the cut plates reach a certain number, it is carried out by the optical computer, and the total control The cutting machine will stop automatically, and the cut plate will be fixed by the fixing device on the side of the conveyor belt, and sent to the material inlet of the production line by the conveyor belt.

The latter is entirely dependent on the mechanical arm, through the suction cup, the plate is sucked up, sent to the production line, and the stamping process is carried out.The stamped materials will be picked up by the robotic arm for various welding and docking operations.

The whole process is completely vacant and unattended by the optical brain. It is only necessary to arrange an inspector at each position that requires quality inspection to carry out the inspection.If you pass the inspection, you only need to press the green button on the console, and the conveyor belt will send the workpiece to the next process. For unqualified workpieces, you only need to press the red button, and the robotic arm will send the workpiece to the next process. Next to the waste port, manual processing is carried out.

For each position that requires manual inspection, only two people need to be assigned to monitor in shifts. The production line is much more convenient.

After the whole vehicle is welded and formed, the mechanical arm is inserted into the engineering hole inside the car shell and under the shell chassis to fix the car shell, send it to the cleaning workshop, invade the cleaning liquid, and carry out cleaning and derusting work.The cleaned car shell is sent to the drying room for drying, and then sent to the painting workshop, where the robot arm performs the painting work.

The car shells that have been sprayed will be sent to the paint baking room for drying treatment. After rows of painted car shells, along with the conveyor belt, after more than an hour of drying, they will be sent to the assembly workshop. Carry out the installation of the engine and chassis suspension. The installed car will continue to move forward to install the seat, and finally, it will be sent to the manual installation workshop.

There are only this workshop, and there are more staff, who will carry out the installation of the electrical part, such as threading, connecting plugs, instrument installation, etc.After a row of procedures, the cars that already have some appearance will be sent to the conveying device, and will be sent to the workshop behind for the installation of the windshield. Finally, they will be sent to the quality inspection workshop for final inspection.

Qualified cars will be driven into the test workshop for various data tests, and then they can leave the factory and be put into storage.In the past, the entire automobile manufacturing plant required thousands of people and could only produce a few cars per day. After adopting the production line, only a few hundred people are needed to complete the installation and commissioning of the entire vehicle, and hundreds of people can complete the work every day. The production task of the car.

If the production line designed by the company can achieve the expected effect, then only 200 people are needed to set up five production lines to carry out production. Moreover, compared with the most advanced foreign automobile production lines, the efficiency will be considerably improved.

After reading all the blueprints, Wang Zhen was also very excited. He called all the experts who were involved in the development of the production line and held a temporary meeting in the research room.

At the meeting, experts from various departments gave detailed introductions to the drawings. Experts who are good at laser positioning also gave technical reports on the positions that need to be precisely controlled. Finally, they demonstrated the animation of the production line.

After the demonstration, the experts introduced the difficulties encountered in the current design.Foreign advanced production lines all adopt point-to-point welding technology to carry out multiple welding of each welding point on the workpiece. The workpiece needs to be moved multiple times on the mechanical arm to carry out the welding work of each point.

The self-designed production line is ready to adopt multi-point and spot welding at the same time. For different workpieces, different molds are used for welding.Just like a turret lathe, various welding molds are designed into a turret type and installed on the mechanical arm.

After the optical brain simulation, the turret is too large, and it is easy to touch the workpiece every time it rotates, and the workpiece will be collided and deformed. Moreover, laser positioning technology is needed to make each rotation in place, which increases the rotation speed. The dimensions of the tower.There has been no better solution to reduce the size of the turret.

Wang Zhen stared at the design blueprint of the turret on the big screen, running at full capacity, and the biological auxiliary chip in the brain was performing various calculations.This is still Wang Zhen, the first time to use it, the auxiliary chip in the brain, to help him perform calculations.Wang Zhen didn't do more design for the turret part. After all, so many experts didn't understand it, and Wang Zhen, an amateur player, couldn't figure it out in a short period of time.

Wang Zhen was mainly doing calculations, changing the position of the mechanical arm. Perhaps, these experts only paid attention to the size of the turret, and they got stuck. They didn't think of solving it in other ways.Everyone saw that Wang Zhen had been staring at the screen without speaking, and was staring at the drawings by himself, thinking of a way, and the research room became quiet.

"Yes." After a few minutes of calculation, Wang Zhen asked: "The mechanical arm is not necessarily fixed on the ground, right? What if a gantry is added? Fixing the mechanical arm on the gantry will not take up space on the ground , not to mention that there will be no collision with the workpiece due to the rotation of the turret."

"That's right, why did we put all our energy on the turret, and no one thought of changing the position of the mechanical arm? If the mechanical arm can be hoisted up, it can indeed avoid the collision of the workpiece." The experts reacted immediately, changed the drawings immediately, and performed calculations.If the mechanical arm is hoisted in the air, vibrations will inevitably occur. In addition to the vibration of the mechanical arm itself, there is also a part of the vibration of the gantry caused by the rotation of the mechanical arm.

After nearly an hour of calculations, the shape, size, and installation location of the gantry were finally determined. When the results came out, everyone cheered excitedly.The overall design of the entire production line is considered complete.

Wang Zhen wanted to inform Chen Yaliang that he was not going back to the company today, but he took out his mobile phone and found that there was no signal, so he remembered that since calling is prohibited inside the research institute, radio signals have been shielded outside the entire research institute, except for the internal Outside of the phone call, you can only make calls in the office of the research institute. This call is not made casually, and requires the approval of the management staff and internal monitoring.

Wang Zhen asked Chen Yaliang to hurry up the establishment of the Chinese Medicine Hospital, and arranged for the grandparents and grandchildren to work in the Chinese Medicine Hospital first, and left behind some old Chinese medicine doctors who had agreed to work in the Shenlong Company's Chinese Medicine Hospital. And made some arrangements for the company's situation.

After making the phone call, I immediately returned to the design institute, the building where I was located, and the designers of the design institute to carry out detailed design work.The drawings of the entire production line were initially designed according to rationality. Although the specific dimensions of the shape were given, the dimensions of some small parts were not standardized.

Wang Zhen is now preparing to work with various experts to design every detail of the entire production line in detail.This design is the longest that Wang Zhen has stayed in the research institute. After the auxiliary calculation of the optical brain computer, the specific dimensions of the various parts were not determined until almost a year ago.

As soon as the results came out, Wang Zhen immediately worked with various experts to name the parts, sort them, and finally make a list.The processing tasks of various parts were assigned to the mechanical processing plant, and some precision parts were allocated, and the precision equipment processing plant was established in less than half a year.For some special bearings, hydraulic presses and other equipment, people were also immediately arranged to order them.
