Application of AGV in Welding Process

AGV replaces manual handling and realizes automated logistics AGV has been widely used in logistics transportation in welding workshops, replacing traditional manual transportation of materials and battery vehicles, forklifts, belt conveyors, buffer and other transmission vehicles and equipment.

Ⅰ. AGV application benefits

1. Save manpower and reduce errors

The application of AGV has changed the mode of logistics and transportation, not only saving labor, but also reducing material supply problems caused by human errors;

2. Reduce security risks

AGV replaces battery trucks, forklifts and other operating vehicles, which greatly reduces the potential safety hazards caused by human-computer interaction;

3. Save space and improve space utilization

The flexibility of AGV solves the problems of large space occupation and difficult transformation of traditional transmission tools. Traction-type AGVs are mostly used in logistics and transportation, which are small in size and low in price. The AGV feeder can be made into a one-piece structure or a split structure (feeder tray + utensils).

Ⅱ. AGV application scenarios

1. Accurate docking of AGV and robot docking

After the AGV material car is in place, if the parts are manually unloaded, the AGV's own accuracy can be satisfied; if the robot automatically grabs the workpiece from the material car, the robot has high requirements on the positional accuracy of the workpiece. The structure of the feed port, the addition of visual recognition, etc., CASUN AGV can achieve accurate positioning of ±5mm, which ensures the precise docking with the robot;

2. The application of AGV in the adjustment line

Traditional welding and adjustment lines mostly use fixed roller bed conveying methods. The workload of each additional model or location transformation is very large, and even needs to be dismantled and rebuilt. In order not to affect the production of models in production, the transformation time is usually very short and the transformation is difficult. 

AGV replaces the application of fixed roller bed in the adjustment line, and designs universal pallets for multiple models or directly switches pallets to meet the requirements of high flexibility of the production line; because the position of the AGV car is not fixed, it can be arbitrarily replaced for production, breaking the fixed demand mode of the line body for space.

3. AGV switches fixtures to realize production self-adaptation

The traditional automobile welding production line is a linear production structure. This production mode is based on the same platform models. When the different platforms are mixed, the use of process equipment will be unbalanced.

The application of AGV brings the possibility to realize the mixed flow function of more models in the production line. In order to meet the mixed flow requirements of more models and increase the flexibility and economy of the production line, the traditional production line is first divided into modules according to functions, and workstations with different functions are established. The workstation is closed or other models are produced at the same time, which not only saves production time, improves the utilization rate of equipment, but also reduces the cost of single-vehicle production.

Using the AGV car can also switch tooling such as fixtures and grippers. Before production, the tooling and fixtures are transported to the line body by AGV, which can realize any multi-model mixed flow in the workstation. Moreover, the tooling of these different models can be stored in a three-dimensional warehouse outside the line, which greatly reduces the demand for production area.

The increasing living standards have also changed people's demand for automobiles. More and more personalized demands are prompting changes in the way automobiles are manufactured. Advanced production lines with high flexibility and high intelligence emerge as the times require. AGV replaces traditional fixed conveyor lines to make production more flexible, breaks the platform limitation of traditional production lines, and can realize mixed-flow production of different platforms and more models; at the same time, it breaks the boundaries of production processes, and can formulate corresponding production processes according to different processes, production path, so as to make more rational use of production resources.
