Countercurrent 1982

Chapter 976

"It is indeed very difficult to start a dual-card recorder with a single motor, but it is not impossible..." Duan Yun paused, and then said: "First of all, we need a very high-quality motor with strong power and good stability. A new integrated circuit and a new electronic servo control mechanism would need to be designed, all of which would require an additional circuit setup, but in general, if one motor drive could be used, the production cost could be greatly reduced...”

"The tape recorder motor is indeed costly. If we can use one less motor, we can save a lot of cost, but the question is where can we buy such a high-quality motor?" asked another professor next to him.

"Actually, the production line we imported from Japan this time can produce high-quality motors..." Duan Yun said.

"But I think the motor production equipment of this imported production line is very ordinary. The production efficiency of two equipment is very slow, which is not as good as similar domestic products." Zhao Xuewu said at this time.

"Master Zhao, you don't really think that the little devil will sell us their complete production line?" Duan Yun said with a smile after hearing this.

"What do you mean?" Zhao Xuewu was stunned for a moment.

"In fact, the motor production equipment on this production line has been castrated. It is impossible for Little Japan to give us the best technology, but in order to facilitate sales, he must maintain the integrity of the entire production line. Under the premise that the best production equipment is sold to other manufacturers, they can only dismantle the key circuit equipment and replace it with old and outdated circuit boards. In this case, the machine can only exert half or even half of the original performance. Lower..." While speaking, Duan Yun picked up the file bag in front of him, and took out a few design drawings from it.

"There is such a thing!?" Hearing this, Zhao Xuewu seemed to realize something.

"...I don't know Mr. Zhao, have you seen the AR-3 automatic winding machine on the production line? The winding machine provided by Honjo Co., Ltd. has 4 rotating winding shuttles, but in actual operation Only two winding shuttles can be used, and the other two shuttles are completely like decorations. I also opened the circuit board of this machine and found that there are many traces of re-soldering on the electronic components. The place where the integrated circuit is marked is empty, which is obviously disassembled..." Duan Yun picked up one of the circuit drawings and put it in front of everyone, tapped it with his fingers, and then said: "And you can take a closer look This drawing, the circuit diagram on it, is obviously different from the current circuit board. Although the electronic components are basically the same, many lines on the circuit board are obviously redundant. In addition, from the paper, this paper is a little yellow , was not drawn at the same time as other product drawings..."

When Duan Yun said this, everyone present was taken aback. After carefully comparing these blueprints, they soon discovered that there was indeed something tricky in them.

"In fact, the tape recorder motors produced by Honjo Co., Ltd. still have a very high share in the Japanese market. The stamping machine for the iron sheet of the motor rotor uses a high-speed punch with high efficiency and high precision. Die forming, the material is the tape that has been coated on the surface, and the multi-station punching machine punches out a part every time, but the surface coating is still not damaged, and the punched parts do not need to be electroplated, which can effectively guarantee Consistency in size, easy assembly..." Duan Yun began to carefully analyze the advantages of this imported production line, only to hear him continue: "In addition to these equipment, there are many other technologies that are very leading in China. The cooperation with the rotating shaft adopts a sliding fit. The surface finish of the commutator is obtained after two times of abrasive belt grinding on a special commutator grinder. During the grinding, the armor is ground and vacuumed, cleaned and dried automatically. This grinding method not only The surface finish of the commutator is improved, and the concentricity between the commutator and the shaft is also improved, which is a very advanced technology..."

Duan Yun was very excited when he said this, because what he said now has involved the advanced core technology of the current domestic tape recorders, and if the production line can be properly modified this time, he has a good chance to reduce the cost of the dual-card recorder. Production costs, to achieve curve overtaking in the domestic market.

After hearing Duan Yun's explanation, several other technicians present became more and more excited as they listened to Duan Yun's explanation. Feeling a little ashamed.

"Manager Duan, you are too good. I'm not flattering you. You are really good. I've been studying the production line in the workshop for the past few days, but I haven't observed it as thoroughly as you. It's really scary..." Duan Yun explained After finishing, Zhao Xuewu said with some emotion.

"Manager Duan, did you really learn electronic technology by yourself?" Yang Xiuchun couldn't help asking.

"I only discovered the problem of this production line equipment occasionally. It's just a matter of luck." Duan Yun replied lightly, and then said: "Our task now is to find out the working principle of this set of motor production equipment, and then rebuild it. To design the circuit so that this set of equipment can play its original production capacity, the second is to learn from the new product design ideas of domestic and foreign counterparts. On this basis, we will strive to design a low-cost single-motor-driven dual-card recorder. This is our research. The first important task after the establishment of the institute, I hope everyone can work together to make new products in the shortest time, I believe everyone has the strength in this regard!"

"Well said!" As soon as Duan Yun finished speaking, Zhao Xuewu took the lead in clapping his hands, and the meeting room immediately burst into warm applause.

And Cheng Qingyan, who had been standing by the side without saying a word, looked at her husband with a bit of surprise and relief at this moment.

"In the future, I will provide enough funds for our research institute. I still have some foreign exchange in my hand. I can buy some similar products from abroad for everyone to disassemble and analyze. In addition, if you have any needs, you can contact me and my wife directly. , or Director Li of the Guangzhou office can help you solve it." Duan Yun said.

"Manager Duan, our research institute is still a little short on staff..." Zhao Xuewu said suddenly at this time.

"I also talked about the issue of the personnel of the research institute with Director Li of our Guangdong office yesterday. He has issued a recruitment notice in Guangzhou City and plans to hire more than 10 highly educated technical personnel to join our electronics factory, so You don't have to worry about the shortage of manpower." Duan Yun replied with a smile.
