Description

[0002] Spraying paint or epoxy paint on the surface of metal workpieces can prevent the metal workpieces from corroding the paint coating. In the spraying process of metal workpieces, traditional spraying systems usually adopt relatively simple fixed stations or manual operation methods. For example, some small factories may only load, spray and unload metal workpieces on a fixed workbench. This method has many defects: First, the production efficiency is low. Due to the lack of automated continuous operation process, the connection between each process requires manual intervention or a long waiting time, resulting in slow overall production speed and difficulty in meeting the needs of large-scale production; second, the loading and unloading of workpieces is not accurate enough and the consistency is poor. It is easy for metal workpieces to be placed inaccurately or fall or collide during the transfer process, thereby affecting product quality and increasing scrap rate; third, during the spraying process, it is difficult to accurately control the uniformity and consistency of the spraying, which often depends on the experience and skills of the operator.

[0078] (1) Workpiece loading
