It should be understood that the following text is only used to describe one or several specific implementations of the utility model, and does not strictly limit the protection scope of the specific request of the utility model.

[0023] like Figure 1 , 2As shown, a device for coating a large-sized workpiece 11 comprises an assembly bracket arranged in a cantilevered manner, the cantilevered end of the assembly bracket is provided with a clamping mechanism for clamping the workpiece 11 to be coated, the clamping mechanism is connected to a driving mechanism, and the driving mechanism is used to drive the workpiece 11 to be coated clamped on the clamping mechanism to rotate. A further scheme is: the workpiece 11 to be coated is suspended and installed on the lower side of the clamping mechanism. The clamping mechanism comprises a clamping plate 10, the clamping plate 10 is arranged horizontally, and the workpiece 11 to be coated is detachably mounted on the lower plate surface of the clamping plate 10. The assembly bracket comprises a cantilever arm 41 arranged in a cantilevered manner, the fixed end of the cantilever arm 41 is fixedly mounted on a mounting plate 42 arranged vertically, and the mounting plate 42 and the frame are adjustably and movably assembled along the length direction of the cantilever arm 41.

[0024] The above solution can adapt to the clamping requirements of workpieces 11 of different sizes, improve the clamping efficiency and clamping reliability of the workpiece 11, and improve the coating efficiency of the workpiece 11.

[0025] The clamping plate 10 is rotatably mounted on the cantilever end of the cantilever arm 41, and the driving mechanism is mounted on the upper side of the clamping plate 10. The projections of the driving mechanism and the clamping plate 10 on the same horizontal plane are respectively recorded as A projection and B projection, and the A projection is located inside the B projection. The clamping plate 10 and the cantilever arm 41 are insulated and assembled by the first insulating member 12. The driving mechanism includes a driving motor 30, and a mounting seat 20 for mounting the driving motor 30 is arranged on the upper surface of the cantilever end of the cantilever arm 41. The mounting seat 20 is provided with a second insulating member 22 for achieving insulation between the driving motor 30 and the cantilever arm 41. A connecting shaft is arranged in the middle of the clamping plate 10, and the output shaft of the driving motor 30 and the connecting shaft are connected by a transition shaft 31. The arrangement of the first insulating member 12 and the second insulating member 22 can effectively ensure the safety of the clamping plate 10 and the mounting seat 20. The mounting plate 42 is provided with various horizontally arranged assembly rods 44, and the assembly rods 44 and the frame are assembled and connected along the length direction of the cantilever arm 41. A limit plate 43 is provided on the plate surface of the mounting plate 42 away from the side of the cantilever arm 41. The limit plate 43 is arranged vertically and the mounting plate 42 is arranged perpendicularly. The limit plate 43 can play a role of limit protection and can also play a role of increasing strength. More specifically, the workpiece 11 to be coated is detachably assembled through the mounting holes and bolt assemblies provided on the clamping plate 10. An auxiliary mounting block 21 for mounting the auxiliary workpiece 11 is provided on the mounting seat 20. The drive motor 30 can be specifically a servo motor. The servo motor provides rotational power for the workpiece 11 and controls the rotation speed, so as to cooperate with the target material for uniform coating. The output end of the servo motor is connected to the clamping plate 10 in a transmission manner to drive the clamping plate 10 to rotate. The cantilever arm 41 can be specifically composed of a cantilever plate body with a horizontally arranged plate surface, and the mounting seat 20 is installed on the cantilever plate body by screw threads. The frame includes an external mounting plate 51, and a control device 60 is also provided on the frame. The control device 60 is used to adjust the operating state of the drive motor 30. The first insulating member serves to insulate the clamping plate 10 and the cantilever arm 41, and the second insulating member 22 serves to insulate the mounting base 30 (driving motor) and the cantilever arm 41. The transition shaft 31 is also made of insulating material. The clamping plate 10 is rotatably mounted on the cantilever arm 41 through a high-temperature bearing.

After the fixed connection, the workpiece 11 is placed above the configuration source of the coating. Then, the assembly rod 44 is installed with the external mounting plate 51. After the clamping plate 10 is fixed to a suitable position, the control device 60 is started, and the drive motor 30 is started. The drive motor 30 drives the clamping plate 10 to rotate while driving the workpiece 11 to rotate evenly, so as to evenly withstand the projection of the target material.

[0027] The above solution provided by the utility model enables large-sized workpieces 11 to be evenly supported during the vacuum coating process, thereby improving the coating efficiency and avoiding the problem of low utilization rate of traditional molds. The rotation speed can be freely adjusted to improve production efficiency. It has a simple structure, low cost and easy operation.
