Lu Chengyu, the director of the factory, told Ye Ran that the magnetic bearing has outrageous requirements for precision, and only a high-precision C machining center can be processed.

At the same time, it is a stainless steel material with a relatively high Mohs hardness, and the processing efficiency is very slow.

Small-scale processing is possible in the factory, but there is no clue about mass production.

Ye Ran asked him if there was a solution?

Lu Chengyu, the director of the factory, said that there must be no solution to the motor factory, and the technical staff of the headquarters has no way.

Now they are looking for a professional precision machining factory, and if they can't help it, they can only use the stupidest way.

The stupidest way is to outsource the magnetic bearing to a large number of precision machining factories, and use enough precision machining centers to pile up the required number of magnetic bearings.

But doing so can be costly.

In addition, the mass production and installation process of grating sensors cannot be solved for the time being.

The encoder sensor is also important, it is used to monitor the position of the magnetic bearing, and it will transmit the data to the control board according to the position, so that the motherboard can properly distribute the electrical signal to the motor.

There are two grating sensors, one in front and one behind, each only the size of a mung bean, which needs to be fixed in a specially machined card slot at the bottom.

Because it is too small and extremely fragile, the induction unit on it can only be installed manually if it is not easy to scratch the upper induction unit during the clamping process.

Lu Chengyu, the director of the factory, told Ye Ran that in order to solve the automatic installation process of the grating sensor, they had turned to a well-known placement machine manufacturing company.

They can come up with a solution, but it takes time to build specialized equipment.

"So how small is the current small-scale mass production?"

Lu Chengyu, the director of the factory, thought about it and said: "The working parameters of the motor have been tested, and it is qualified. ”

"At full speed, it should be no problem to produce 2,000 motors a day."

"When necessary, we can have more workers to manually assemble the encoder sensors."

"But Mr. Ye, you also know that without automatic assembly equipment, the output can not be piled up infinitely by hand, after all, assembling grating sensors is also a technical job."

Ye Ran nodded in understanding.

The encoder sensor is not just a press of a button into the reserved card slot.

It also needs to be fixed with anti-vibration glue, and the cable must be attached to the inner shell, and finally the wire is connected to the main line at the tail of the motor.

It doesn't feel like it's too technically difficult, but sometimes it can be a single step that can stump an engineer who is proficient in automation.

For example, the Apple mobile phone seems to have an extremely precise internal motherboard and components, but many steps still need to be done manually when it is assembled.

However, although there are still such and such problems, the magnetic levitation linear motor can finally be mass-produced on a small scale.

This is a huge breakthrough from zero to one.

As for the production of magnetic bearings, it simply depends on the quantity to pile up, and it doesn't matter if the cost is high, consumers pay for it.

The motor is the core component of the cleaning instrument, and if the placement machine manufacturing company solves the problem of automatic assembly of the grating sensor, all the problems will be solved.

Song Yu also asked Ye Ran at this time, how is the progress of the chip company?

"It's going well, and they'll send the first batch of chips the day after tomorrow."

"Then we can make a cleaner."

Song Yu clapped his hands and said longingly: "If the sales of the cleaning instrument are good, even if it is assembled manually, we will pile up the production capacity." ”

"It's not good on the motor company's side, and there's the headquarters."

"There are a lot of people at the headquarters, as long as there is an order, I can take the management to assemble it in person."

Song Yu fully expounded what it means to "put the interests of the company first".

"Then build it, I'll have no problem here."

Song Yu clenched his fists, "It's okay on my side." ”

……

Just do it.

After Ye Ran and Song Yu returned to Wuzhou, they immediately pounced on the production process of the cleaning instrument.

Shuangke Industry is responsible for the production of motors, brush head coatings, shell coatings, power supply batteries, and charging docks.

Two Angel Technology is responsible for the production and assembly of shells, motherboards and chips, aluminum alloy main frames, as well as screens and switches.

There is no problem with chip foundry, and there is naturally no problem with the motherboard.

The rest is not technically difficult.

It just so happens that the sales of bath gel have been good in the past few days, and those users have also confirmed the receipt in advance under the stimulation of the new product experience qualification.

Now there are more than 10 million funds in the company's account, and Ye Ran has all smashed them into the purchase of related production equipment.

And pay half upfront with a careful budget, so that you can buy more equipment.

Two days later, the chip company sent the first batch of 1,000 chip samples.

These chips are then sent to the motherboard foundry, which encapsulates the chips to the motherboard.

At the same time, Two Angel Technology continues to recruit, this time with young workers recommended from the talent market and labor market, many of whom have experience working in electronics factories.

The assembly of the cleaner is also on the first floor of the building, but the injection molding equipment and the C machining center are on the second floor.

Shuangke Industry is also moving very quickly, and even if the motor can only be produced in small batches, it must be fully produced.

The coating materials used in the cleaner are also prepared and ready to be sprayed.

The batteries used in it are procured from outside, and the charging docks can be produced by their own factories.

Two days later, with the efforts of the workers, the shell of the cleaning instrument was injection molded, and more than 2,000 sets of aluminum alloy main frames were processed.

At the same time, the parts that were made to order from outside factories were also basically delivered.

Screen.

Integrated push-button switch, as well as vibration frequency speed control switch.

Charging module, all kinds of waterproof sealing rings, matching screws, quick-plug wires, etc.

These small parts, along with those individual parts, make up the main body of the cleaner.

The drive motherboard and magnetic levitation linear motor have also arrived.

The small batch assembly of the cleaner officially began.

The assembly is a multi-functional assembly line assembly table mode, each worker is responsible for an assembly process, the parts that need to be assembled are placed on the workbench, and the main body of the cleaner is conveyed to each assembly worker by the conveyor belt.

Assembly is the easiest part.

First of all, the two shells that have been polished and trimmed, after the assembly worker gets the shell, the screen module and the button module are screwed to the shell, and then transferred to the next worker.

This worker was responsible for the installation of the aluminum alloy frame, which was also an upper and lower structure, fixed to the housing by card slots and screws.

This is followed by shock-absorbing film, and a core magnetic levitation linear motor.

The workers responsible for assembling the magnetic levitation linear motor should firmly attach the motor to the shock-absorbing film, and then put the screws into the reserved holes of the motor screws and fix them in the aluminum alloy frame.

The next worker is responsible for equipping the waterproof seals of the housing.

There are hundreds of assembly processes in total, but each process does not have any technical difficulties.

Now there are two assembly lines, and in half a day, they have successfully assembled 2,000 cleaners.

Next, these semi-finished products of the cleaner will be sent to Shuangke Industry for coating spraying process.

Coatings are divided into brush head coatings, as well as main body shell coatings.

The cleaner has to deal with water, so waterproofing is the top priority.

After the shell coating is sprayed, the silicone coating seals the shell completely, providing the most important first layer of waterproofing.

In the evening, Song Yu came.

She was accompanied by a GL8 containing 2,000 finished cleaners with brush head coatings and shell coatings.
