[YesAuto Factory Secret] Brilliance Jinbei Automobile began producing the fourth-generation Sea Lion in 1989, and has experienced 27 years of development. The Jinbei Sea Lion series and Gress products using Toyota technology have penetrated into people's lives in recent years. Whether it is daily sourcing or general business reception, their presence is never unfamiliar to us. So, today we will walk into their production base to briefly understand how the Jinbei Sea Lion series and Ge Ruisi products are produced.
The Brilliance Jinbei factory was established in 1989 with a total investment of US$570 million. The factory covers a total area of nearly 500,000 square meters. There are four workshops in the factory area: stamping workshop, welding workshop, painting workshop and final assembly workshop. The designed annual production capacity reaches 150,000 vehicles.
At the beginning of the stamping workshop, this 6300 kN (approximately 642.6 tons) fully automatic uncoiling blanking production line, the maximum uncoiling width of the line is 2 meters. The steel enters the production line from the uncoiler, and is decontaminated and flattened by the washing machine and straightener, and then cut to the required length by the blanking press, and then stacked by the magnetic transmission belt.
The stamping workshop of Brilliance Jinbei can produce panels for BMW, Zhonghua and Jinbei series models. Among them, this 2000-ton stamping production line is equipped with 5 large mechanical presses, which are grasped by 7 manipulators from Gude, Switzerland. The maximum production cycle of this line is 12 pieces per minute.
For example, the inner and outer panels of the sliding door of Ge Ruisi are produced on this 1,600-ton stamping line. The manipulator here is provided by ABB. The punched side sliding door inner panel enters the quality inspection area, and workers will control the number of holes and appearance quality.
The welding workshop can be divided into the sea lion series model welding area and the Ge Ruisi/Hua Song welding area. Due to the longer body of light passenger products such as Ge Ruisi, they are divided into front frame and rear frame to be welded separately. After that, the two are welded together with the floor.
When the production line arrives at the lower car body welding station, workers use welding torches for welding, and then repair welding by robots. This station uses 6 FANUC (yellow) and 8 Kawasaki (white) robots. Robot repair welding is mainly used for difficult welding joints to ensure the quality of the welding joints.
At the end of the main welding line, workers should inspect the main body assembly, make corrections and polish necessary places. Similarly, in this station, workers use carbon dioxide shielded welding to weld the automatic gear bracket; and install the front door hinge.
The body-in-white enters the paint shop, after pre-treatment, it will enter the electrophoresis tank. A layer of electrophoretic coating film will be formed on the surface of the body steel plate, this layer of coating film can play a high anti-corrosion effect on the outer panel and inner cavity of the body.
Before spraying the chassis paint, workers will install shielding enclosures on the front wheel to prevent external splashing during painting; at the same time, plastic protective covers should be plugged in the holes at the bottom such as screws. The holes are protected. The spraying of the chassis paint can effectively prevent the impact and friction of the fine sand.
In the spraying of the top coat, Goruisi has 5 colors, while the Sea Lion series has only one white. First, the A-pillar, B-pillar, and top of the vehicle compartment are painted manually, and some parts that are difficult to be sprayed by the robot are sprayed. Then, the spraying robot from Japan's Taikisha will spray all around the body.
Different from the assembly sequence of other factories, the center console of Hiace and other models was installed very early, and the assembly started just after the main wiring harness was installed in the final assembly shop. Moreover, it is not an assembly, like the instrument panel, audio system and air conditioning panel, etc. will be assembled on it.
In the three installation positions of the engine assembly, rear axle and fuel tank, the AGV fully automatic assembly trolley provided by Siasun is used. It not only saves manpower, reduces labor intensity, but also improves production efficiency.
The gluing of the front and rear windshields is done by Motoman robots to ensure the accuracy of gluing. And in conjunction with the turning machine, after the glue is applied, the workers can better facilitate the suction cup to grab.
On the final assembly line, for light passenger models, it is mainly for the installation of more seats, but in this factory, it is still carried by hand. After completing all the installation procedures, the vehicle will arrive here after passing the four-wheel alignment, light inspection, hub inspection and other inspection lines, and the final inspection will be carried out under parallel light, and the offline will be completed. In addition to the above, the Brilliance Jinbei factory will have some more distinctive features according to its own production needs. We will give you a detailed introduction in future factory visit articles.
