The so-called plug-in machine is a mechanical device that automatically inserts some regular electronic components into the conductive through holes on the printed circuit board.

The traditional electronic assembly industry mainly relies on workers to insert electronic components into the circuit board, since the machine began to mass-produce manual plug-ins slowly, the curve of poor process is exposed, and the electronic components are automatically installed on the circuit board with the plug-in machine, which can pick up labor costs and improve his process.

In later generations of electronic enterprises, the placement machine is more commonly used, in fact, the placement machine and the plug-in machine belong to a type of equipment, but the plug-in machine appeared earlier, is to insert some of the larger parts with pins on the PCB board machine, and later with the progress of technology, the more and more originals, the more and more flake-like shadowless foot originals, the placement machine also came into being, the placement machine is a machine for placing small chip IC components, which is equivalent to the upgraded version of the plug-in machine, the difference is that the materials installed on the board of the two machines are different.

Because the small tape recorder produced by Duan Yun and the originals on the circuit board of the Walkman are relatively dense, if they are assembled by hand, the speed will be very slow, and the process is also poor, so in order to solve this problem, Duan Yun must have plug-in equipment.

"I've read about plug-in machines in electronic magazines before, and if you want to buy this kind of equipment, it's too expensive, at least a few million dollars, and you can't necessarily buy it, can our factory come up with so much money?" Zhao Xuewu said.

At present, only the United States, Japan and European countries can produce this kind of plug-in machine in the world, there is no such technology in China, and the cost of this machine is very expensive, often millions of dollars, in the plug-in machine used by Sony Electronics Factory at that time, for example, the cost of each unit is about 1.2 million to 3 million US dollars, such a price is not out of the domestic enterprises, even if it is a foreign company, in addition to some large international manufacturers, the general enterprises can not afford such equipment.

In fact, from the cost point of view, if it is not the kind of product with particularly high profits, the use of this equipment is also a very luxurious thing, in fact, in later generations, at the end of the 90s, there were some domestic manufacturers, including joint ventures, have introduced this plug-in machine, but compared to cheap labor, many enterprises later abandoned this equipment, and re-used manual operation.

Therefore, it is reasonable for Zhao Xuewu to raise such a question at this time, millions of dollars to buy the same equipment, the wear and tear and maintenance costs during the period are also very high, there is no way to show in China, and once the machine cannot operate, the entire production line will face the danger of shutdown, and the loss caused is also very large.

"We definitely can't afford the plug-in machine now, but we can consider making one, this kind of equipment is very important, without an automatic plug-in machine, our production efficiency and quality will not be able to improve......" Duan Yun said with a frown.

"Let's make our own plug-in machine!?" Hearing this, Zhao Xuewu was stunned in surprise.

Automatic plug-in machine is a relatively advanced equipment in the world, only the United States, Japan, Germany and France can produce in the world, and the cost is also very expensive, the country has only started research in related fields, and a lot of scientific research has been invested in this regard, but many core technologies have not broken through, and Duan Yun actually claimed to independently develop the plug-in machine, which made Zhao Xuewu feel that Duan Yun was a little born calf is not afraid of tigers.

"I will solve the problem of the plug-in machine, our machinery factory has high-precision CNC lathes, and many parts can be processed by themselves, which should save a lot of money. Duan Yun said.

"Manager Duan, you're not kidding, can you make a plug-in machine?" Zhao Xuewu said with wide eyes.

Obviously, in Zhao Xuewu's opinion, Duan Yun said that he could build a plug-in machine is simply a fantasy, this thing The country has invested so much manpower, material and financial resources, and has not made a technological breakthrough until now, and Duan Yun actually said that one person can build it, if it is not bragging, then Duan Yun is definitely a genius.

However, what Zhao Xuewu would not have thought of was that Duan Yun was a doctor of electronic engineering mechanics in his previous life, and he still knew a lot about the plug-in machine, and he once had a paper on the optimization and improvement of CNC plug-in motors, so it was not difficult for Duan Yun to design a set of plug-in machines that could be practical.

"It's a matter of man, maybe it's done. Duan Yun smiled, then turned around and left.

After leaving the electronics factory, Duan Yun soon came to the machinery factory again.

Entering the workshop, Duan Yun saw at a glance that Erhu and Professor Peng Changming were standing in front of the two CNC machine tools, talking about something with each other.

"Master, you're here!" After the sharp-eyed army saw Duan Yun, he immediately hurried up to meet him.

"Master Peng is also there. Duan Yun smiled and greeted Peng Changming.

Peng Changming is the only professor of the Department of Mechanical Engineering in Duan Yun's R&D team, and has participated in the development of new armored vehicles in the country, and is also a top scholar and expert in the field of domestic machinery.

"Is there anything wrong with Manager Duan?" asked Peng Changming.

Peng Changming is a little withdrawn compared to several other professors, but he himself still admires Duan Yun, after coming to Shenzhen, he saw that Duan Yun's Longteng Machinery Factory actually has high-end equipment such as a CNC machining center, which is a big shock to his heart, and during this time, through communication with Duan Yun, he found that the young man in front of him is far higher than he imagined, even when it comes to some high-end topics in the field of machinery, Duan Yun can completely keep up with the rhythm, no worse than himself, so in Peng Changming's view, Duan Yun is simply a rare genius。

Duan Yun's initial intention to establish Longteng Machinery Factory was to develop and produce automotive transmission products, but in terms of the current national conditions, the national policy does not allow private enterprises to enter the automotive field, so up to now, Longteng Machinery Factory can only rely on the OEM of Red Star Labor Service Company to maintain normal operation, but can not independently produce its own transmission products.

It is very costly to build one of the top automobile transmission manufacturers in China, even if Duan Yun has a loan of more than 20 million yuan, but this money is still far from enough, and the research and development of high-end gearbox products is a bottomless pit of burning money, without a fund of tens of millions of yuan, it will not be able to play at all.

So the current situation is that Duan Yun needs to make money from the electronics factory first, and at the same time accumulate product technology, and wait until the capital accumulation reaches a certain level, and after the country's policy on the private automobile industry is relaxed, the focus will be shifted to the machinery factory, and strive to occupy a place in China's automobile industry......
