[0002] Aluminum plate refers to a rectangular plate made by rolling aluminum ingots. It is divided into pure aluminum plate, alloy aluminum plate, etc. Aluminum plate is mainly used as a decorative plate in the field of life. When the aluminum plate is produced, it needs to be cut and stamped first, and punched when the aluminum plate is stamped. After the aluminum plate is stamped, the lower end surface of the stamping is prone to bulges or burrs. Therefore, the burrs on the surface of the aluminum plate need to be removed before the processing is completed.

[0003] A Chinese patent with the authorization announcement number CN111070010B discloses a surface treatment device for aluminum plate after punching and an aluminum plate surface treatment process. The surface treatment device for aluminum plate after punching includes a bottom plate, a limit side plate, a cleaning mechanism, a cleaning slide column, a position adjustment mechanism, a positioning mechanism and a push cylinder. A limit side plate is installed at both ends of the top of the bottom plate, and a limit groove is provided at the upper end of each limit side plate. The cleaning mechanism is located between the two limit side plates, and the left and right ends of the cleaning mechanism are connected to the inner end of a cleaning slide column. The present invention solves the problem that the strength is not easy to control when manually grinding the aluminum plate, which easily causes the aluminum plate to be incompletely polished or the aluminum plate to be damaged by excessive grinding strength, and the burrs or protrusions will be polished into the holes of the aluminum plate when the aluminum plate is manually polished, resulting in poor burr cleaning effect of the aluminum plate.

[0004] The existing surface treatment scheme after punching of aluminum plates cannot adapt to deburring punched aluminum plates with holes of different sizes, especially when the arrangement positions and arrangement numbers of the holes are different, the existing device cannot better play the effect of deburring the holes. Summary of the invention

[0041] refer to Figure 1As shown, the present invention also includes a method for surface treatment of an aluminum plate, which specifically includes the following steps:

[0042] Step 1: Place the drilled plate on a conveyor belt and convey it to the plate surface grinding mechanism 2 to deburr the surface of the plate;

[0043] Step 2: After the board surface is processed, the conveyor belt conveys one end of the protective cover 11 and conveys it to the top of the grinding mechanism 2 through the conveyor roller 13;

[0047] At the same time, when the grinding assembly 3 is at the peak position and in contact with the plate surface, the grinding block 33 drives the lifting plate 32 to descend and compresses the elastic support 34. At the same time, since a ball 339 is provided on the top of the grinding block 33, the grinding block 33 is prevented from scratching the surface of the plate. When the grinding assembly 3 moves to the plate hole, the elastic support 34 drives the lifting plate 32 to reset and pushes the grinding block 33 into the plate hole.
