Big Country Intelligent Manufacturing

Around seven o'clock in the evening, the big meeting room of Mingxin Manufacturing Company.

Xu Zhenming, Hu Mingzhen, Wan Guning, Zhang Nyijing and others are holding a large-scale technical seminar. The theme of the meeting is how to solve the problem of vibration wave resonance between the various sub-systems of the lithography machine.

At this moment, the meeting has been going on for about half an hour. The central idea of ​​the meeting has changed from solving the connection and assembly of the laser optical system and the host system to the assembly connection problem of the lithography machine sub-system.This is the case for technical people, a small problem can be extended to a large subject.

Through the discussion just now, Xu Zhenming extended this issue again, and has expanded it to what issues should be addressed in the assembly assembly of CNC machine tools and CNC machinery.

"Everyone, I have a good idea. How about bringing Hong Aiguo's team to this meeting?" Xu Zhenming smiled at Mimi's questions of the experts present.He believes that the team engaged in CNC machine tool manufacturing should be able to provide better solutions and systematic technological solutions.

"Well, you are the boss, you have the final say." Everyone thought.

As the person in charge of this project, Hu Mingzhen, he couldn't help but frown slightly at this time, "What is the use of Lao Hong and the others coming to the meeting?" Even though he thought so, he nodded freely, "Xu Dong's proposal is very Good, very timely."

Hu Mingzhen did not insist on his opinion today, but because he felt that he was a bit wrong, he was embarrassed to refute Xu Zhenming's opinion.If he followed his past temperament, he would definitely use the excuse that "time is too late".

Through today’s lithography tape-out test, Professor Xu Zhenming, Professor Hao Ning and others discovered the design flaws in the resonance of the domestic lithography machine components. The design team led by Hu Mingzhen should bear the main responsibility.

For any team engaged in equipment research and development, the structural calculation and mechanical calculation of the equipment body resonance are the first.But Hu Mingzhen’s team did not find this problem, it has been negligent.Although Xu Zhenming didn't point it out, Hu Mingzhen could still pick it up.

"Xiao Zhao, you immediately call Director Hong and ask him to come and help us on the staff." He then called his assistant Xiao Zhao and gave a call in Xiao Zhao's ear.

Xiao Zhao was very quick to do things, and quickly got things done.

Fortunately, Hong Aiguo was also working overtime today. It didn't take long before he came to the conference room.

"Come to me, Lao Hong." Xu Zhenming beckoned to him when he saw Hong Aiguo's blank face.

When Hong Aiguo sat down beside him, he lowered his voice and explained to Hong Aiguo, "Lao Hong, the main system of the lithography machine manufactured by your factory has a major problem, and we are in a meeting to find a solution."

"Ah..." Hearing this, Hong Aiguo's face suddenly changed, and Monk Zhang Er was puzzled.

Seeing this scene, everyone couldn't help laughing, and the tension in the meeting room suddenly became relaxed.

"Cough, cough!" Hu Mingzhen couldn't laugh, and coughed a few times to hide his embarrassment.

When everyone calmed down, he lay out the problem in a slow manner, "Director Hong, we have a problem now. The third-generation lithography machine under development, the main system and the laser optical path system have resonance. What should we do in this situation?"

"Well..." Hearing this, Hong Aiguo suddenly felt a little big.

Machine tool design and equipment design must do a good job of mechanical model calculations in advance, and equipment resonance has long been avoided through various processing methods such as materials, heat treatment, mechanical structure, and connection methods.But now that the various components of the lithography machine system have been shaped, redesign is no longer possible.

What should I do?

Thinking of this, Hong Aiguo touched the sparse hair, and after some consideration, he asked slowly: "Mr. Hu, can our lithography machine perform major surgery?"

"No, there is no time for major changes to be made now." Hu Mingzhen denied Hong Aiguo's proposal on the spot.

In his view, major surgery or adjustment of the basic materials and structure of the lithography machine should be considered when designing the next generation lithography machine.The current thinking should be slightly adjusted to solve the problem quickly.

"Let me talk about my views." At this moment, Liang Songsong raised his hand to speak.He saw that Hu Mingzhen and the others had no good solutions, and Hong Aiguo, who had just invited, didn't come up with any good plans. He immediately felt that he could take action.

"Huh?" When everyone saw Lao Liang's application to speak, they all immediately turned their attention to this person.

At the meeting just now, Liang Songsong had been named by Hu Mingzhen, and he didn't say a good plan at the time. How could he suddenly be inspired.Everyone present attentively raised their ears, ready to listen to Liang Songsong's brilliant tricks.

"Cough!" Liang Songsong coughed dryly and cleared his throat.

"Xu Dong, teacher, and colleagues, I think we can solve the resonance problem between the laser optical system and the main system without major changes. The two systems are not matched, so why solve the resonance of the two systems? Let's It should be considered in terms of the installation method..."

Liang Songsong spent five or six minutes recounting his ideas.

His plan is very mature, and he has obviously considered it for a long time, unlike what he came up with after being inspired on the spot.

Liang Songsong's plan is very simple, cutting off the connection mechanism of the laser optical system to solve the problem of the installation distance between the two sets of equipment.Then make a base for the laser light path system, and install the laser light path system and the main body system of the lithography machine separately to isolate the resonance problem between the two systems.

This method is very simple, fast, and can solve the problem quickly.It can also solve the problem of the distance between the laser head and the lithography table.

"Well, this plan can be used as one of the alternatives." After Hu Mingzhen understood the plan, he was the first to praise Liang Songsong.

But he was still a little bit reconciled, "This will destroy the structure of Mi's domestic laser optical system, and it can only be used when there is no other way."

"I don't think this plan will work!" At this moment, Hong Aiguochao had just finished speaking, and Liang Songsong, who was in a good mood, smiled apologetically.

Under normal circumstances, this old man will not offend people.After decades of wrestling in society, Hong Aiguo has become very smooth.But when it comes to principles, he still has to tell the truth, otherwise I am sorry for Xu Zhenming's favor.

"Well, Hong Lao has a better plan?" Liang Songsong looked at Hong Aiguo with a dry smile.

According to his inner vision, Xu Zhenming's attention was drawn to Xu Zhenming through this lithography machine project, and he earned a lot of bonuses and share awards.But now Hong Aiguo has come forward to make trouble, how can this be done?

When everyone saw this scene, they immediately felt that the atmosphere in the conference room was a bit different, and turned their attention to Hong Aiguo.

Hong Aiguo smiled at this time and touched the bald forehead again.

"I have a few immature suggestions, and I don't know if I can solve this resonance problem." As he spoke, he turned his face and looked at Xu Zhenming.
