The production line of welding workshop mainly includes: floor line, side line, body assembly line and body additional line.
In order to cope with the welding accuracy of the eighth generation Camry with high rigidity, 1 13 sets of high-speed robots, high-pressure welding guns, electrode head forming machines, new gluing robots, etc. Added to additional production lines and assembly lines.
In order to ensure the welding quality, this production line introduces the plastic robot of the electric level head, which will be repaired once after each welding to ensure the state of the electric level head and the quality of each solder joint.
Compared with the traditional total loss detection, ultrasonic detection improves the detection efficiency, reduces the scrap rate of parts, quantifies the solder joint strength from the data, and provides data support for the strength assurance of the whole vehicle.
On-line laser measurement is the technology adopted by most advanced factories at present, and TNGA production line is no exception.
Laser on-line measurement can detect the installation accuracy of various parts of the car body and realize the real-time accuracy detection function, mainly measuring the gap and segment difference between the fender and the front door, the front door and the rear door, and the rear door and the side wall. It can provide comprehensive and valuable data to analyze the changing trend of volume accuracy and eliminate the quality difference in the bud.
Painting workshop: The task of the painting workshop is to paint the white body completed by the welding workshop layer by layer. In addition to strengthening the rust prevention of the car body, it is mainly to make the car body look more beautiful. The process of painting generally needs to go through cleaning, electrophoresis, painting, varnish and other steps.
From the preparation before painting to the completion of two-color body painting, there are more than 50 steps than the ordinary version of car paint, 165 minutes of production process, in which the interface of two colors needs to be checked within 30 minutes.
Assembly workshop: The assembly workshop is the last workshop of production, where all parts will be assembled. At this time, the painted body, interior powertrain and chassis will be assembled into a complete car.
The assembly workshop includes three production lines: the assembly line of powertrain and chassis, the internal assembly line and the assembled assembly line of powertrain and chassis and body.
This has higher requirements for the overall alignment accuracy of the equipment, and the relative angle deviation between the engine and the chassis is required to be less than 0.2 degrees, otherwise it cannot be installed and transported. In order to improve quality and efficiency at the same time, TNGA production line adopts chassis adapter with higher precision.
Summary:
After the eighth generation Camry, a new model under the framework of TNGA, was introduced into China, due to its substantial improvement in quality, each upgrade point needs a series of matching upgrades in the factory, which is of great significance not only for this product at present, but also for other models of GAC Toyota in the future.
