Description

Technical Field

[0001] The utility model relates to the technical field of production and processing of vacuum coating machines, in particular to a workpiece fixing device for vacuum coating machines. 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 a Chinese utility model patent with a publication number of CN219508012U. The above-mentioned prior art can clamp products of different lengths, which expands 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 the opposite direction at the same time. The operation is simple and the labor intensity is low. However, different workpieces have different sizes. The fixture is a kind of fixing device. It is troublesome to remove the general fixing device after installation. In this way, when different sizes of workpieces need to be coated, the fixing device cannot be moved to adjust the position, the density of the fixing device cannot be adjusted according to the size of the workpiece, and the workpiece cannot be placed more reasonably. When the fixing device is sparse, the coating efficiency will be reduced, and more workpieces cannot be coated at one time. When the fixing device is dense, the coating space will become smaller, the coating speed will be slower, and the coating quality and speed will be reduced. Therefore, it is necessary to design a workpiece fixing device for a vacuum coating machine that can adjust the number and position of the fixing device according to the size of the workpiece during coating. Utility Model Content

[0024] The present invention is further described below in conjunction with the accompanying drawings and specific implementation methods. It should be noted that, under the premise of no conflict, the various embodiments or technical features described below can be arbitrarily combined to form a new embodiment.

[0025] Please combine Figure 1-Figure 3 A workpiece fixing device for a vacuum coating machine according to the present embodiment comprises a main shell 1, an auxiliary shell 2 is arranged on one side of the main shell 1, and adjustment components for adjusting the coating position of the workpiece are arranged inside the main shell 1 and the auxiliary shell 2, and each adjustment component is provided with a plurality of fixing components for placing and fixing the components to be placed, and a plurality of hanging components for hanging the workpiece to be hung for coating are arranged on one side of each fixing component.

[0026] Combination Figure 1 and Figure 2The adjustment component includes two sliding rings 301 fixedly mounted on the inner wall of the main housing 1 and having a first sliding groove, and a plurality of movable plates 302 slidably arranged between the two sliding rings 301 and having a second sliding groove. By sliding the movable plate 302, the fixed component on the movable plate 302 can be replaced accordingly.

[0027] Combination Figure 3 The fixing component includes a sliding block 401 slidably installed on one side of the adjacent moving plate 302 through an adjacent second sliding groove and a placing plate 402 fixedly installed on one side of the sliding block 401. Limiting plates 6 are fixedly installed on both sides of the placing plate 402. A fixing column 7 is provided on one side of the two limiting plates 6. One end of the two fixing columns 7 penetrates the adjacent limiting plates 6 and is fixedly installed with a clamping block 8. The two fixing columns 7 are each sleeved with an extrusion spring 9, one end of which is fixedly installed with the adjacent clamping block 8 and the other end is fixedly installed with the adjacent limiting plate 6. A limiting block 10 is fixedly installed on the other end of the two fixing columns 7. A threaded column 11 is provided on one side of each sliding block 401. One end of each threaded column 11 threadedly penetrates the adjacent sliding block 401 and fits with one side of the adjacent moving plate 302. A rotating block 12 is fixedly installed on the other end of each threaded column 11. When the workpiece is placed on the placing plate 402, it will be clamped and fixed by the two clamping blocks 8.

[0028] Combination Figure 3 A plurality of third sliding grooves are provided on one side of the display plate 402, and the hanging assembly includes a moving block 501 slidably installed inside the third sliding groove and a hook 502 fixedly installed on one side of the moving block 501, and the hook 502 can hang the workpiece that needs to be hung for coating.

[0029] Combination Figure 2 Scrapers 13 are fixedly installed on both sides of each movable plate 302, and one side of each scraper 13 is set in an inclined shape. When the movable plate 302 moves, the scraper 13 will simply scrape and clean the inner wall of the main shell 1.

[0030] The implementation principle of a workpiece fixing device for a vacuum coating machine in the embodiment of the present application is as follows: when coating different workpieces, the corresponding fixing components are replaced according to the needs of the workpieces. The movable plate 302 is first slid and taken out from the main shell 1 and the auxiliary shell 2, so that the fixing components will be taken out together, and then the movable plate 302 with the corresponding fixing components installed is reinstalled into the main shell 1 and the auxiliary shell 2, and the fixing components can be replaced. After the replacement, the threaded column 11 is rotated to loosen the fixing effect of the sliding block 401, so that the sliding block 401 can slide on the movable plate 302. After the position of the sliding block 401 is determined, the threaded column 11 is rotated in the opposite direction to move the sliding block 401. Fix it, so that the position of the display plate 402 can be adjusted according to the workpiece. This arrangement allows the space inside the vacuum coating machine to be utilized to the maximum extent, and will not allow the fixed components to occupy a large amount of space, resulting in poor coating efficiency, nor will it cause a small number of fixed components to be coated together, affecting the production speed. After the position is determined, the workpiece is placed on the display plate 402, and the two limit blocks 10 are pulled, which will allow the fixed column 7 to drive the two clamping blocks 8 to move. After loosening the limit blocks 10, the two clamping blocks 8 will clamp and fix the workpiece under the push of the extrusion spring 9. When the workpiece needs to be suspended for coating, the hook 502 can be used to cooperate with the workpiece for suspension and fixation.

[0031] 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.
