The assembly line system is definitely one of the greatest inventions in the history of human industry, and its inventions and creations have directly helped mankind to rise several levels.

From the birth to the perfection of a set of assembly line system, I don't know how much time has gone through and how many times it has undergone continuous changes.

The system proposed by Qiu Qiu is basically the same as the assembly line of later generations.

The only difference is that they haven't made the most of it, but that's to be expected, they've only made new adjustments in terms of personnel, but not much in terms of the working environment.

But even so, within just five days, almost all the workers were familiar with their new jobs and their responsibilities, and after ten days, they were basically familiar with what they had to do.

A month later, the entire assembly line has been able to operate normally, and the production speed has been infinitely close to the goal of their meeting a month ago, and now the average time required to work at each station is about half an hour, and in hours, it is about an hour and fifteen minutes.

The timing was completely acceptable, and the most surprising thing was that the final assembly workshop was now able to assemble nine trucks a day on one assembly line.

The entire assembly plant has nine assembly lines, 81 trucks a day, and with the proficiency of workers, this speed is still improving, and finally reaching the goal of producing 10 to 12 trucks per day on an assembly line, which is infinitely close.

The output of nearly 100 trucks a day, this news deeply shocked the entire imperial court, and even Li Yuanji was frightened.

After asking, I understood the real reason, but even so, Li Yuanji decided to take the minister to visit in person.

Of course, Qiu Qiu, as the first contributor to improving this production line, naturally entered Li Yuanji's sight.

A flat-bottomed board truck, the length and width are not large, just the chassis of the truck is supported on it, and then the entire board truck is sent to the first station, a group of ten workers, instantly surrounded, ten people around a chassis, a little crowded, but in fact it is not.

Everyone's position and corresponding work are arranged in advance, everyone knows what they should do, and only needs to be responsible for the work within their own responsibility, and other people's work does not need them to worry about it at all.

The team leader is in charge of the overall situation, and is responsible for the core of the team, and it is also the most demanding process, which may not be the most difficult on the whole car, but it is the most demanding process at this station.

After completion, everyone checks their own work, the team leader is personally inspecting, and at the same time calling the next team to check, after confirming that it is correct, directly pull the car to the next station, and then repeat the same work here.

"Your Majesty, there are a total of nine working groups in the workshop here, according to the time required for each process to divide the responsibilities of the station, to ensure that the working time of each station is about half an hour, and the biggest advantage of this is to further simplify the number of technologies that workers need to master, now on average each person only needs to be responsible for two to three processes, after doing this, the vehicle will be transferred to the next group, and then they will carry out the next assembly.

At the beginning, the assembly plant adopted a team responsibility system, that is, each team was responsible for assembling a truck, but the system was only implemented for one day, because there were too many problems, far from meeting expectations, and because there was a better system, so the system was abandoned and the current one was adopted.

However, at present, the minister feels that there is still room for improvement, which is also the direction of the minister's efforts, and this workshop still needs some changes, because at the beginning, I didn't expect it to be this result, but the overall change is not big, and some fine-tuning in the local aspects can be done......" Liu Shan pointed to the assembly line in front of him, and his heart was full of pride.

There is no reason not to be proud, because this has created a precedent for Datang, which is also an artillery factory with assembly line production, and the output of one day is far inferior to that of the machinery factory.

After the truck assembly plant achieved amazing results, this system was quickly extended to the second agricultural machinery assembly plant, where after becoming proficient, the output of these days is also rubbing upward.

Accessories factory is a little embarrassed, accessories are not assembly, some processes can be separated, some can not be separated, anyway, after a toss, the production mode has changed some, the efficiency has also improved, but compared with these two assembly plants, the improvement is not big.

The ministers were like peasants in the countryside who had entered the Grand View Garden, although they had also seen assembly line production, but this kind of assembly line production was the first time they had seen it.

The previous assembly line is that several people cooperate to complete the manufacture of a product, whether it is speed or quality, in the case of qualified accessories, this quality is no problem.

But the assembly line in front of me has nearly 100 people, and the nine stations are connected together, basically from this end of the workshop to that end, and some of them have turned around and back.

On the other side, it used to be a workstation, but now it can only be used to store parts and components.

The ministers watched the excitement, but Li Yuanji saw the problem.

If you haven't eaten pork, haven't you ever seen a pig run?

The problem of this assembly line is not big or small.

What makes Li Yuanji feel that he can't see it the most is that the whole process needs to be pushed by manpower, that is, it needs to rely on the trailer under the chassis to support, and then the manpower pushes it to the next process.

In Li Yuanji's impression, this link can also be operated mechanically, after completion, press the start button, it will automatically leave the workbench and enter the preparation area, and then the next working group presses the button, and the vehicle in the preparation area enters the next workbench.

This greatly saves the problem of waste of manpower, but now, it seems that it is not suitable.

You can't just build such a piece of equipment and make a steam engine burn on the side, not to mention, according to the current situation, most of them are moved in half an hour, and the steam engine keeps burning, which is also a waste of power.

In the back station, even the installation of the steam engine relies on manpower to manipulate the equipment and put it up.

If this is acceptable, then the other is completely unacceptable, or unacceptable.

Welding problems.

Whether it is a truck or any other vehicle, welding is always inseparable.

At present, Datang has only three welding technologies, casting welding, that is, two parts are welded together with lead-tin alloy or copper.

Forging culvert is to heat the overlapping positions of two parts together, and then forge them to connect them together.

The last one is brazing, that is, the melting point of the brazing metal is lower than that of the weldment, and the two are heated at the same time, the brazing metal melts, the weldment is red, and then it is filled with a liquid so that it can be joined together.

At present, Datang is the most widely used is this kind of brazing.

However, construction vehicles such as trucks and agricultural vehicles such as tractors require more force.

Then the problem comes, the brazed connection is not the strongest, and under the long-lasting strong stretching, it is easy to deform and fall off.

Putting it in the car means that it will fall apart when you run, which is very dangerous.

The reason why the construction of steel battleships has temporarily stopped is that the problem of welding technology cannot be solved.

This technology can be used for small-scale welding, such as the battleship that requires comprehensive welding, which simply cannot support its use strength.

Because there is already a precedent on a battleship, and then on a truck, it becomes a little more cautious.

Li Yuanji had never seen how trucks were made before, but now he finally knew.

In order to solve this problem, it can be said that the craftsmen are also racking their brains.

They even took a double insurance in a frenzy, every part that needs to be welded, before welding, will first make a hole in it, and then use screws to tighten and fix, which is the first insurance, and then welding is the second insurance, and at the same time welding the screws to prevent falling off.

Li Yuanji felt a little speechless, but it was hard to say anything, after all, the problem of welding did exist.

The best way is to get electricity out, but unfortunately, about electricity, Li Yuanji can only helplessly say that he can't do anything, he really doesn't know anything about this, and he can't even say some of the most basic suggestions, at most, he will tell you a circuit or something, but there is an egg?

But even so, Li Yuanji is very satisfied with the current situation.

A machinery factory with less than 5,000 people, you can do nearly 100 Nissan trucks, even if the production capacity is separated, the existing personnel can also do 50 Nissan trucks, more than 20 other construction machinery, the tractor is simpler, at least compared to the truck, the personnel there are not much different from here, the operation is relatively simple, the process is less, hundreds of tractors a day is still very easy.

There are 3,000 tractors, more than 1,000 trucks and hundreds of construction vehicles a month, which is enough for Datang to need at the moment.

"What is the production capacity of the parts factory?" Li Yuanji asked, an assembly plant has only two parts factories, one is still only responsible for the chassis and other large parts, the pressure in this area is not great, but the pressure on the parts side is too great.

"The production capacity is a little unable to keep up, if we start working at full speed, we will work non-stop for two days, which is enough for one day of production here." Liu Shan responded honestly.
