[0002] With the development of science and technology, the technology of welding robots has developed rapidly. In welding work, robots are gradually used to replace manual welding, which not only improves the welding speed but also the welding quality. In the welding work of forklift truck frames, welding robots are mainly used for welding, mainly because welding robots have the characteristics of low labor intensity, accurate welding, and continuous uninterrupted work, and can greatly improve the welding efficiency. Therefore, welding robots are widely used in the welding of forklift truck frames.

[0003] When traditional robot welding workstations face the welding of large-sized workpieces, due to the limited movement range of the robots, multiple robots are often used in cooperation for welding; when facing workpieces of multiple specifications, multiple workstations are often established, and each workstation welds workpieces of one specification to solve this problem, or when one workstation is welding, the subsequent welding workstations are in a waiting mode, unable to reach the production beat required by users. This results in low equipment utilization rate, poor efficiency, and often problems such as misloading, missing loading, and non-standard operation sequence, wasting financial and material resources.
