Welding line/BIW Engineering

Welding line

Project introduction: Light truck cab assembly automatic welding line. The four models are on the same line, with an annual output of 50,000 units and 14 KUKA robots.

Automobile body welding production line is one of the important production lines in the production process of cars, minibuses and other models. From the perspective of the development history of the automobile industry, the body welding line has experienced manual welding lines in the 1950s and 1960s to automated rigid welding in the 1970s. Assembly line - the stage of robotic flexible welding assembly line after the 1980s.

Development Trend of Automobile Welding Production Line

At present, the development trend of the world's automobiles is from mass production to multi-variety and small-batch production. In order to meet the extensive and diverse needs of automobile consumers and adapt to the fierce competition in the automobile market, major automobile manufacturers in the world continue to shorten the model change Cycle, to speed up the update of vehicle types, so the modern automobile welding line is gradually becoming more flexible in function.

Automatic production line for single vehicle

The typical form of the production line is shown in Figure 5. It generally uses fixed special fixtures and cooperates with manipulators for automatic welding and assembly. Materials are automatically transported and put in by cranes, and reciprocating shuttle machines are often used for product transportation between each station. It is characterized by high production efficiency, high degree of automation, and stable quality, but it is still a single-species production line.

horizontal moving device

The working principle of this part has been mentioned above, simply put, the rack and pinion device in the drive unit drives the moving slide to drive the workpiece to move horizontally. It is worth mentioning that the positioning block installed on the mobile skateboard mainly plays the role of positioning the workpiece, and the form of the positioning block for the side wall of different models is also different. If you want to weld the side wall of other models, you only need to replace the positioning block. Other parts do not need to be greatly modified. Compared with the traditional transmission device, this method has been further developed towards flexibility.
