The main purpose of Chen Xu's visit to Minxi Industrial Zone is to inspect the technical situation of the domestic robot industry.

Those online analyses and surveys will never be true and effective from first-hand information.

In addition to the inspection, he also wants to acquire several robot core component factories for technical upgrades to prepare for the future robot assembly production.

I plan to buy a sensor factory, or a servo motor factory.

Needless to say, how important the sensor is, this thing is like the eyes, ears, tongue and nose of humans;

In addition, there is a robot servo motor, which is also very important, which is something that truly reflects the industrial foundation, which requires multi-axis synchronization and good flexible control.

Of course, in the end, it also depends on the control algorithm.

Algorithm garbage, no matter how awesome the servo motor is, it is in vain.

It's kind of a ring after a ring.

Chen Xu drove past a factory, and when he saw something interested, he stopped and went in to have a look.

These manufacturers are really diverse, and they have everything.

Optoelectronic module factories are divided into 40 or 50 types, such as diodes, light-emitting diodes, temperature control switches, LED screens, microphones, crystal oscillators, fuses, resistors, potentiometers, buzzers, battery boxes, chips, Dupont wires, electronic component packages, and solar epoxy panels.

And don't look at the small scale, some even have three or five people and a few pieces of equipment, but the products made are really good, and the quality is better than the bargains he bought on the Internet before.

Many of them are outsourcing companies of large companies, and all kinds of quality certificates are readily available.

It is impossible to admire.

After inspecting an obstacle avoidance sensor manufacturer, it was just noon, and Chen Xu went to eat on the street of the industrial park.

I looked at more than a dozen in the morning, and two sensor factories were more satisfied, although the price was not discussed, but it was estimated that it was between 800 ~ 10 million.

But there's no hurry.

Go to the supermarket to buy a paper towel to compare the quality and price of the goods, buy a robot parts factory such an important thing, you must run two more and then decide.

After eating, turn onto the industrial zone avenue and continue to drive in the direction of Jiaotong University in the south. China Overseas Jiaotong University and East China Normal University are both within the Minxi Industrial Zone.

After driving less than 100 meters, Chen Xu noticed that in the middle of the two machinery factories and the plastic technology factory, there was an inconspicuous small company, the company name was "Zhonghai Yuchi Wireless Charging Technology Co., Ltd."

Chen Xuleng paused, wireless charging?

In fact, he just saw a lot of wireless charging companies with different names on both sides of the road, but he subconsciously didn't think about what they did, because he had been thinking about sensors and motors in his mind, and he ignored them.

But at this moment, he suddenly thought of a very important thing.

In the robot components, there is actually one core component that is not valued: the battery!

There is no need to repeat how important batteries are to an electronic product.

The reason why robot batteries are not valued is because there will be no revolutionary breakthroughs in battery technology in the short term, so no one bothers to work on it. Just like electric cars, in the final analysis, it is nothing more than superimposing batteries, 8, 16, 32, and 64 more.

It is precisely because there will be no breakthroughs in battery technology in the short term, so researchers from all walks of life have set their sights on charging technology.

There are currently six wireless charging technologies, or concepts.

1. Electromagnetic induction;

2. Magnetic resonance;

3. Radio waves;

4. WiFi wireless charging;

5. Ultrasonic wireless charging;

6. Focus the light.

The electromagnetic induction technology of the first of these has already been implemented and is already being used in mobile phone charging.

The technical principle is that the charging base and the mobile phone terminal have built-in coils respectively.

When the two are close, the transmitting coil generates a certain current in the receiving coil of the mobile phone based on a certain frequency of alternating current through electromagnetic induction, so as to transfer the point energy from the transmitter to the receiver, and then it can be charged from the charging base to the mobile phone.

Because of the simple principle and easy production, coupled with the promotion of Texas Instruments, Philips, Toshiba, Microsoft, Panasonic, Samsung, Sony, Apple, Qualcomm and other manufacturers, wireless charging has been widely used in the market.

However, there is a disadvantage of wireless charging based on electromagnetic induction, that is, the transmission distance is seriously limited, and the longest distance in the laboratory is about 10 cm, and the power is cut off when it is taken away from the charging base in actual use.

If you want to continue playing, either hold the phone and the charging base in both hands, or you change the data cable.

So the wireless charger is actually a chicken rib, many people buy it back and use it once and then don't use it again, throw it away, and keep it without eggs, not to mention that it still occupies space.

At this time, looking at this "Yuchi" wireless charging company, Chen Xu had a lot of thoughts in his mind.

Battery technology is not considered for the time being, but this wireless charging technology is worth a good study.

Once long-distance wireless charging can be realized, not too far, a room or a room is enough, it is also a great invention, and it plays a vital role in solving the charging problem of robots and other various electronic products.

Not to mention anything else, there will be absolutely a lot of money at that time.

Thinking of this, Chen Xu immediately pushed the car door and walked down.

When he came to the factory gate, Chen Xu told the security guard that he had come to inspect the products, and if he was satisfied, he would buy them back.

When the security guard heard this, coupled with the BMW SUV parked at the factory gate, he immediately opened the electric door, and then took Chen Xu to the office behind the factory.

When the supervisor in charge of sales heard that Chen Xu was coming, he originally planned to show him a sample.

But at Chen Xu's insistence, the sales supervisor took him to the production workshop.

The factory is not small, there are more than 1,000 square meters from the door, three production lines, and the product area is full of products to be shipped.

However, Chen Xu noticed a detail, the inspection date on the front packaging was already March this year.

In other words, this factory has not shipped for three months.

In addition, the factory is also deserted, and several forklifts are quietly placed there, and there are no workers loading and unloading goods.

And the assembly line is also empty, and no one can see it.

Chen Xu asked, why didn't work start?

The sales executive began with a few perfunctory words.

But in the face of reality, after the sales director sighed, he said helplessly: "When it came out in 17, it was popular for a while, but it was not good in the second half of last year."

Everyone is piling up to produce, and the price is pressed one by one.

You are like our company, the raw materials of the shell, motherboard and coil are better, a cost price is 45 yuan, but the retailer's quotation is only 50, except for the storage and transportation and labor costs, no profit is lost. ”

After a pause, the sales supervisor said: "Now we are selling at cost price, and we will still do our old business after the funds are returned." ”

Chen Xu asked, "What are you doing?"

The sales executive said: "R&D of electronic accessories. ”

Chen Xu was a little surprised, "You are still engaged in the research and development of electronic accessories?"

The sales executive smiled with a hint of pride: "Our boss is a doctoral student born in technology and a 10th class of information technology at Aoki University. ”

"Oh, yes. Chen Xu was a little surprised, he didn't expect to meet future alumni here.

Originally, he was not interested in this factory, anyway, it was some outdated technology, and there was no equipment worthy of his attention;

After communicating with the sales executive, Chen Xu followed him to Yuchi's electronics research institute.

Yuchi Electronics Research Institute is located in a science and technology park not far from Jiaotong University.

The so-called research institute is not big, it is a little larger than the laboratory he rented, about 300 square meters, counting the boss of Yuchi who is not here, there are 9 researchers in total.

Chen Xu visited the research institute, and all kinds of experimental equipment were piled up everywhere in the room.

Just when Chen Xu was visiting, Su Zhengxiang, the boss and technical director of Yuchi, came over......
