The moment Duan Yun pressed the button, the motor started, and the conveyor belt slowly converged the circuit board and parts from the two staggered lines to the middle.

"Click! Click!"

Under the power of the cylinder, the plug quickly and accurately clamped the parts on the upper conveyor board, and then instantly inserted the small hole corresponding to the circuit board, and the three plugs operated at the same time, and it took less than 5 seconds to accurately insert more than a dozen electronic components into the circuit board.

Seeing this scene, the eyes of everyone present flashed with excitement, except for Duan Yun and Zhao Xuewu, who went abroad together, everyone else watched the work of the plug-in machine for the first time.

Immediately afterwards, the second, third, and fourth circuit boards were also quickly plugged in, and the finished product slid down the conveyor belt and into the finished box, which was astonishingly efficient.

The next moment, Duan Yun and Zhao Xuewu walked quickly to the finished box, and each picked up a finished circuit board and looked at it.

"The accuracy is very good, and it looks very good. Zhao Xuewu showed a satisfied smile after looking at several circuit boards in a row.

"The subsequent soldering work also requires a printing table and a tin pot so that the finished product can be made. Duan Yun picked up a few boards and looked at them, then nodded and said.

After the completion of the most critical plug-in tool, the remaining circuit board soldering is relatively simple in terms of technology, that is, the method of dip soldering, Jiang has placed the PCB board of electronic components and put it a few millimeters above the printing table equipped with rosin alcohol solution, and the lower part of the rosin alcohol solution is blown and foamed, so that the rosin alcohol solution is smeared on the PCB board, and then the PCB board is put on the suction furnace and left to cool after welding, which is also a common soldering method used by many electronics factories in the market, which is simple and efficient, suitable for mass production.

However, compared with the plug-in machine, the printing plate and suction oven for welding are much simpler, and they can be purchased directly from China, and the price is also very cheap.

"Bang Bang!" Seeing the completion of several PCB board plug-ins, the scene suddenly burst into warm applause.

"I really didn't expect that we really made this price difference machine. Zhao Xuewu said with some emotion.

"Thanks to Professor Peng, if he hadn't made the cylinders and gearing, we wouldn't have been able to build this machine. As Duan Yun spoke, he turned his head and saw Peng Changming on the other side.

At this time, Peng Changming was engrossed in staring at the operation of the cylinder of the plug-in machine, and did not seem to hear the conversation between Duan Yun and Zhao Xuewu.

In fact, at this time, Peng Changming's heart has not been completely relaxed, although he is very confident in the cylinder he made, but without a long time of actual testing, it cannot prove that the cylinder he made is successful.

"Manager Duan, can you put some more originals for testing. A few minutes later, seeing that the last circuit board plug-in was completed, Peng Changming turned his head and said to Duan Yun.

"It's too late tonight, the workshop is empty, my suggestion is that everyone go back and rest first, and start the second week of machine testing tomorrow. Duan Yun stepped forward and patted Peng Changming on the shoulder, smiled and said to him: "If there is no problem with the operation, the follow-up rosin printing table and tin furnace for welding will also be handed over to you to do, it has really worked hard for you these past few days." ”

"The printing table and the tin pot are good to say, I have seen that thing before, the technical content is not high, we have ready-made raw materials and machine tools, I can make it in three days at most, and it is guaranteed to be used with this plug-in machine." Peng Changming said confidently.

With Peng Changming's technical attainments, it is not a problem to make a printing table and a tin pot, the only difficulty is how to perfectly connect with this plug-in machine to complete the entire circuit board component soldering tool.

"Congratulations, Manager Duan!"

"It's really good. ”

"It seems that the new production line will be ready for production soon. ”

Everyone present stepped forward to apologize to Duan Yun at this time.

In the past half a month, everyone in the institute has been working overtime every day, almost a state of forgetting to sleep and eating, and now they have finally completed the test of the most critical equipment of the entire production line, which is a great encouragement to the morale of the entire R&D team.

And for Zhao Xuewu's people, they came to Shenzhen thousands of miles away for this moment.

"Everyone is very tired today, let's go back and rest first, thank you for your contribution to the factory, here I decide, after the new product is officially put into production, I will give you a heavy reward, I promise that everyone will get the due reward for their efforts. Duan Yun said to everyone.

"Everyone has worked hard, let's go back first. Zhao Xuewu also said at this time.

They are all retired and elderly people, and they have been working overtime for more than half a month, everyone is very tired, and Zhao Xuewu is also worried about what will happen to his colleagues, so he also quickly settled them back to rest.

"Then we're leaving. ”

When everyone heard this, they left the dust-free workshop one after another, and everyone had a smile on their faces and looked very excited.

Duan Yun and Zhao Changfeng were the last to leave, and when they walked out of the door of the workshop, a cool wind blew in front of them, and the sky was hung with a little starlight, which seemed extremely quiet.

Duan Yun took out a cigarette and handed it to Zhao Changfeng, and after the two of them lit the cigarette, they let out a sigh.

"My dad is right, you are indeed not an ordinary person, and you will definitely be able to make a career with you. Zhao Changfeng took a puff of his cigarette and turned his head to Duan Yun and said.

"You are the tiger father without a dog, if it weren't for your help, my new production line wouldn't have been so smooth, and you have made a great contribution this time,...... Speaking of which, when I was in the factory before, Secretary Zhao was the person I respected the most, but it was a pity that he won everyone, but in the end he lost in time and age......" Duan Yun also said with some emotion.

"Their generation is like an animal in a cage, even if they have great ability, they can only spend their years in a small circle......" Zhao Changfeng took another puff of cigarette, and then said: "But we have a broader sky, I can see that people like you will never be willing to be only a rich little boss, I feel lucky to be a boss like you......"

"I can succeed without your help to me, we are a team, no one can leave, I also hope that you can stay in the company to help me." Duan Yun said with a bit of sincerity in his tone.

Duan Yun still takes a fancy to Zhao Changfeng, among the backbones around him, Zhao Changfeng's ability should be the strongest, and he is very young, even if there are many talents joining now, no one can replace Zhao Changfeng's position in Duan Yun's team.
