Description

Technical Field

[0001] The utility model relates to the technical field of vacuum coating machine processing equipment, in particular to a clamp for a vacuum coating machine. Background Art

[0002] Vacuum coating machine mainly refers to coating equipment that needs to be carried out under a higher vacuum degree, including vacuum resistance heating evaporation, electron gun heating evaporation and magnetron sputtering, etc., which are mainly divided into evaporation and sputtering. Vacuum coating is widely used, so it is also necessary to optimize the components of the vacuum coating machine.

[0003] For example, a coating fixture for a vacuum coating machine is disclosed in the Chinese utility model patent with the announcement number CN219508012U. The above-mentioned prior art can clamp products of different lengths, thus expanding the scope of application. At the same time, it is only necessary to pull the plug out of the socket and then rotate the gear disc to drive the two clamps to move in opposite directions at the same time. The operation is simple and the labor intensity is low. However, when vacuum coating is performed, the coating material will diffuse inside the vacuum coating machine, so that the coating material inside the machine is more evenly distributed. However, when the workpiece to be coated is close to the position where the coating material is sprayed, the sprayed coating material will first contact the surface of the workpiece and then be dispersed in the air. At this time, the surface of one side of the workpiece already has a layer of coating, and the workpiece will not move. The continuous spraying and dispersion of the coating material will cause uneven coating on the surface of the workpiece, which has a certain impact on the workpiece that requires very fine processing. Therefore, it is necessary to design a vacuum coating machine fixture that can prevent the same position of the workpiece from being continuously sprayed with coating material during vacuum coating. Utility Model Content

[0004] In order to solve the technical problem that the continuous spraying and spreading of coating materials during vacuum coating will cause uneven coating on the surface of the first workpiece contacted, the utility model provides a clamp for a vacuum coating machine.

[0005] The utility model is implemented by the following technical scheme: a clamp for a vacuum coating machine, comprising a main shell, a secondary shell is arranged on one side of the main shell, a plurality of rotating components are arranged inside the main shell for allowing the workpiece to rotate and revolve during vacuum coating, a plurality of clamp components for fixing the workpiece for coating are arranged on one side of each of the rotating components, and a support component for supporting the fixed workpiece is arranged on one side of each of the clamp components.

[0006] Through the above technical solution, the rotating component will drive the fixture component to revolve and rotate during vacuum coating, so that the coating of the workpiece is more uniform.

[0010] Through the above technical solution, the driving gear cooperates with the gear ring to realize the rotation of the support rod, and the support rod can complete the rotation and revolution under the drive of the rotating disk.

[0011] As a further improvement of the above scheme, the clamp assembly includes a sliding block slidably arranged on one side of an adjacent mounting plate through an adjacent sliding groove, a mounting frame fixedly installed on one side of the sliding block, and extrusion columns arranged on both sides of the mounting frame, one end of the two extrusion columns passes through the mounting frame and is fixedly installed with a clamping block, the outer surface of each of the extrusion columns is sleeved with an extrusion spring, one end of which is fixedly installed with the adjacent mounting frame and the other end is fixedly installed with the adjacent clamping block, and one end of each of the extrusion columns is fixedly installed with a limit block.

[0014] Through the above technical solution, the sliding block can be moved by rotating the threaded column, and the position of the mounting bracket can be adjusted accordingly.

[0015] As a further improvement of the above scheme, the support assembly includes a rotating column fixedly mounted on one side of the mounting frame, a support plate rotatably mounted on one end of the rotating column and a support column fixedly mounted on one side of the support plate, and the support column is arranged in a conical shape.

[0016] Through the above technical solution, after the clamping block clamps the workpiece, the workpiece can be placed on the supporting column for support.

[0017] Compared with the prior art, the beneficial effects of the present invention are:

[0026] Combination Figure 1 and Figure 2A rotating disk 11 with a motor slot is rotatably installed inside the main housing 1, and a servo motor 12 is fixedly installed on the inner wall of the main housing 1 inside the motor slot. A driving rod 13 with one end fixedly installed on the rotating disk 11 is fixedly installed on the output end of the servo motor 12. A gear ring 14 is fixedly installed on the inner wall of the main housing 1 and provided with a plurality of gear slots on the outer surface of the rotating disk 11. The rotating assembly includes a support rod 301 rotatably installed on one side of the rotating disk 11, a driving gear 302 fixedly sleeved on one end of the support rod 301 and meshed with the gear ring 14, and a mounting plate 303 arranged on one side of the support rod 301 and provided with a sliding groove. A plurality of fixing rings 15 fixedly sleeved on the support rod 301 are fixedly installed on one side of the mounting plate 303. When the servo motor is started, the rotating disk 11 will drive the rotating assembly to rotate, and the driving gear 302 cooperates with the gear ring 14 to realize the rotation of the support rod 301, and the rotation and revolution of the support rod 301 can be completed under the drive of the rotating disk 11.

[0027] Combination Figure 1 and Figure 3 The clamp assembly includes a sliding block 401 slidably arranged on one side of an adjacent mounting plate 303 through an adjacent sliding groove, a mounting frame 402 fixedly installed on one side of the sliding block 401, and extrusion columns 403 arranged on both sides of the mounting frame 402. One end of the two extrusion columns 403 passes through the mounting frame 402 and is fixedly installed with a clamping block 6. The outer surface of each extrusion column 403 is sleeved with an extrusion spring 7 fixedly installed with the adjacent mounting frame 402 at one end and the adjacent clamping block 6 at the other end. One end of each extrusion column 403 is fixedly installed A limit block 8 is installed, and a threaded column 9 is provided on one side of each sliding block 401. One end of each threaded column 9 is threaded through the adjacent sliding block 401 and fits with one side of the adjacent mounting plate 303. The other end of each threaded column 9 is fixedly installed with a rotating block 10. The sliding block 401 and the mounting plate 303 slide together to change the distance between the two mounting frames 402, which is convenient for adjustment without replacing the clamp assembly. Under the push of the extrusion spring 7, the extrusion column 403 will clamp and fix the workpiece with the clamping block 6.

[0028] Combination Figure 3 The support assembly includes a rotating column 501 fixedly mounted on one side of the mounting frame 402, a supporting plate 502 rotatably mounted on one end of the rotating column 501, and a supporting column 503 fixedly mounted on one side of the supporting plate 502. The supporting column 503 is arranged in a conical shape. After the clamping block 6 clamps the workpiece, the workpiece can be placed on the supporting column 503 for support.

[0029] The implementation principle of a clamp for a vacuum coating machine in the embodiment of the present application is as follows: when vacuum coating a workpiece, the positions of the multiple mounting frames 402 are adjusted according to the size of the workpiece, the threaded column 9 is rotated to release the fixing effect of the sliding block 401, and after the multiple mounting frames 402 are slid to the appropriate position, the threaded column 9 is reversely rotated to fix the sliding block 401, so that the position of the clamp can be quickly adjusted. When fixing the workpiece, the two limit blocks 8 are pulled to move the extrusion column 403 and the clamping block 6. After the workpiece is placed between the two clamping blocks 6, the limit block 8 is released, and the two clamping blocks 6 will clamp the workpiece under the push of the extrusion spring 7. Finally, the support plate 502 is rotated to allow the support column 503 to be located at the bottom of the workpiece, thereby fixing the workpiece. The parts have a certain supporting effect, and the conical setting can reduce the contact area with the workpiece. The servo motor 12 is started, and the driving rod 13 drives the rotating disk 11 to rotate. The rotation of the rotating disk 11 will drive the support rod 301 to rotate, and the support rod 301 will revolve along the center point of the rotating disk 11. While rotating, the driving gear 302 fixed on the support rod 301 will mesh and rotate with the gear ring 14 due to the movement, so that the support rod 301 will rotate on its own. In this way, when coating is performed, the workpiece installed on one side of the support rod 301 will be driven by the support rod 301 to rotate, so that the sprayed coating material will not always contact one workpiece surface first, so that all workpieces can be coated more evenly.

[0030] The above-mentioned implementation modes are only preferred implementation modes of the present invention, and cannot be used to limit the protection scope of the present invention. Any non-substantial changes and substitutions made by technicians in this field on the basis of the present invention shall fall within the scope of protection required by the present invention.
