Because its excellent physical characteristic, copper alloy plate is widely used in manufacturing wire, connector, radiator and various mechanical parts. However, the surface treatment is particularly important in the use of copper alloy plate, can effectively improve its corrosion resistance and aesthetic, prolong its service life. In the surface treatment process of copper alloy plate, spraying technology is a common and effective method.

[0003] The patent with publication number CN212349226U discloses a beryllium copper alloy plate surface spraying turnover device, which comprises a turnover structure and a spraying head. The turnover structure comprises a connecting box, a vertical lifting cylinder is arranged at the bottom of the connecting box, a placing rack is arranged at one side of the connecting box, one side of the placing rack is connected with one end of a connecting shaft, a first bevel gear is arranged on the connecting shaft, a second bevel gear is connected with the first bevel gear in a meshing manner, the second bevel gear is arranged on a rotating shaft, the rotating shaft passes through the top plate of the connecting box and is arranged, a mounting seat is arranged on the inner wall of one end of the connecting box, a bearing connected with the other end of the connecting shaft is arranged in the mounting seat; the lifting cylinder is symmetrically arranged on the bottom plate of a mounting frame, a horizontal spraying pipe is arranged on the top plate of the mounting frame, through the arrangement of the turnover structure and the meshing of the bevel gears, the placing rack is driven to rotate, and the beryllium copper alloy plate is turned over, thereby facilitating the spraying processing of the plate.

[0004] However, although the prior art provides a certain solution through the turnover structure, there are still obvious deficiencies in its operation. The meshing transmission mode of the bevel gears of the turnover structure requires two workers to simultaneously operate the rotating shafts of the two turnover structures to smoothly turn over the plate, thereby increasing the complexity of manual operation.
