Welding shop:
The work of the welding shop is mainly to assemble the panels produced by the stamping shop and supplied by suppliers into a complete body in white.
The production lines of the welding workshop mainly include: floor line, side panel line, body assembly line and body addition line.
In order to cope with the welding accuracy of the eighth-generation Camry’s high-rigidity body, 113 sets of high-speed robots, high-pressure welding guns and electrode head shaping were added to the additional welding lines and assembly lines. machines, new glue coating robots, etc.
In order to ensure the quality of welding, this production line has introduced an electric level head The plastic shaping robot will perform a repair after each welding to ensure the condition of the electrode head and the quality of each solder joint.
Compared with traditional full-destruction inspection, ultrasonic inspection improves inspection efficiency and reduces the scrap rate of parts. At the same time, it quantifies the strength of solder joints from data, providing a basis for the complete vehicle Strength guarantees are backed by data.
Online laser measurement is a technology currently used in most advanced factories, and the TNGA production line is certainly no exception.
Laser online measurement detects the installation accuracy of various components of the car body and achieves real-time accuracy detection functions. It mainly measures the gaps and steps between the fender and the front door, the front door and the rear door, and the rear door and the side panel. It can provide comprehensive and valuable data to analyze the changing trend of vehicle body accuracy and nip poor quality in the bud. Painting shop:
The task of the painting shop is to apply layers of paint to the body-in-white completed in the welding shop. In addition to strengthening the body against rust, it mainly makes the body look more beautiful. The coating process generally requires steps such as cleaning, electrophoresis, color paint, and varnish.
From the preparation before painting to the completion of two-color body painting, there are more than 50 steps and 165 minutes more production process than the ordinary version of car painting. Two of the color interfaces require 30 minutes to inspect.
Final assembly workshop:
The final assembly workshop is the last workshop in production. All parts will be assembled here. At this time, the painted body and interior powertrain will be assembled. The components, chassis, etc. are assembled together to form a complete car.
The final assembly workshop includes three production lines: the powertrain and chassis assembly line, the interior assembly line, and the assembled powertrain, chassis and body assembly line.
This places higher requirements on the overall alignment accuracy of the equipment, which requires the relative angular deviation between the engine and the chassis to be less than 0.2 degrees, otherwise it cannot be installed. In order to improve both quality and efficiency, the TNGA production line uses higher-precision chassis switching parts.
Summary:
After the eighth-generation Camry, a new model under the TNGA architecture, was introduced to China, due to its substantial improvement in quality, every improvement point needs to be corresponding in the factory There are a series of supporting upgrades, which not only have great significance for this current product, but also have a lot of room for quality upgrades for other GAC Toyota models in the future.
