[0002] Hardware spraying is a surface treatment technology that evenly sprays paint on the surface of hardware to achieve the purpose of protection, decoration and special functionality.

[0003] In the prior art, when the hardware is sprayed on the assembly line, the hardware plate is usually first hung on a hook that is fixed to the structure and moved by a plate chain or a conveyor belt. The hook is fixed in direction, and then the hardware plate is transported to the spraying area. The staff holds a spray gun and sprays from one side of the plate. After the spraying is completed, the other side is sprayed. The spraying area is generally also equipped with an exhaust device to absorb and collect excess paint droplets scattered in the factory to protect the safety of employees.

[0004] However, this spraying method requires two workers to spray the panel from both sides in turn, and exhaust devices need to be fixedly installed on both sides of the panel, which is costly and inefficient.
