Description

Technical Field

[0001] The utility model relates to the technical field of clamps, and more specifically to a loading clamp for a vacuum coating machine. Background Art

[0002] A vacuum coater is a device used to deposit thin films on the surface of materials. It forms a uniform film layer by evaporating or sputtering the target material in a vacuum environment. It has a wide range of applications, including optical coatings, electronic components, decorative materials, etc. Vacuum conditions help reduce oxidation and contamination, and improve the adhesion and density of the film layer. Depending on the process, vacuum coaters can use different technologies, such as evaporation coating, magnetron sputtering, etc., and are suitable for a variety of materials and substrates.

[0003] The vacuum coating machine requires different loading fixtures when processing different products. At present, when coating cups, the fixture used is relatively simple, which is just an inclined hanging rod. The cups are turned upside down on the hanging rod when loading. However, when the coating machine is working, the loading fixture rotates. Under this mounting method, the cups cannot be effectively supported. During the rotation of the loading fixture, the cups will produce irregular shaking, which may cause uneven coating and affect the coating effect. Therefore, it is urgent to design a vacuum coating machine loading fixture to solve the above problems. Utility Model Content

[0021] Figures 1 to 5 This is the best embodiment of the present utility model. The following further describes the present utility model in conjunction with the attached Figures 1 to 5 drawings.

[0022] A loading fixture for a vacuum coating machine includes two rotating frames 1 and a plurality of vertical rods 2, and further includes a bent rod 3, a fixing component 4, a supporting component 5 and a pushing component 6. The vertical rods 2 are fixedly installed between the two rotating frames 1. The bent rod 3 is fixedly installed on the outer wall of the vertical rod 2, and the number of bent rods 3 fixedly installed on one vertical rod 2 is four. The fixing component 4 is fixedly installed on the top of the bent rod 3. The supporting component 5 is rotatably installed on the fixing component 4, and the number of supporting components 5 rotatably installed on one fixing component 4 is four. The pushing component 6 is slidably installed in the fixing component 4. The pushing component 6 is connected to the four supporting components 5, and when the pushing component 6 is squeezed, it can push the four supporting components 5 to rotate. The fixing component 4 includes a fixing rod 401 and a plurality of ear plates 402. The fixing rod 401 is fixedly installed on the top of the bent rod 3. Two ear plates 402 are in a group and are respectively fixedly installed at both ends and on both sides of the fixing rod 401. A chute 403 is opened at the top of the fixing rod 401. The supporting component 5 includes a semi-gear rotating block 501, a hollow sleeve 502, a threaded rod 503 and a supporting head 504. The semi-gear rotating block 501 is rotatably installed between the two ear plates 402. The hollow sleeve 502 is fixedly installed at the bottom of the semi-gear rotating block 501. The threaded rod 503 is slidably inserted into the hollow sleeve 502. The supporting head 504 is fixedly installed at the bottom of the threaded rod 503. The supporting head 504 is made of heat-resistant silicone rubber. The pushing component 6 includes a sliding rod 601, a bracket 602 and four racks 603. The sliding rod 601 is slidably inserted into the chute 403. The bracket 602 is fixedly installed on the outer wall of the sliding rod 601. The four racks 603 are all fixedly installed at the bottom of the bracket 602, and the four racks 603 are respectively engaged with the four semi-gear rotating blocks 501.

[0023] In this embodiment, during use, the cup is placed upside down on the top of the sliding rod 601 and then released. When the cup touches the sliding rod 601, the gravity of the cup will press the sliding rod 601 to slide downward, thereby driving the bracket 602 and the four rack bars 603 to slide downward. The downward sliding of the four rack bars 603 will drive the four semi-gear rotating blocks 501 to rotate clockwise, thereby lifting the four hollow sleeves 502, the four threaded rods 503, and the four support heads 504. When the four support heads 504 rise to contact the inner wall of the cup, they can support the cup, improving the stability of the cup during rotation and the uniformity of the coating.

[0024] Specifically, a threaded collar 507 is rotatably installed at the bottom of the hollow sleeve 502, and the threaded rod 503 is slidably inserted into the threaded collar 507 through a thread.

[0025] In this embodiment, during use, by rotating the threaded collar 507, the threaded rod 503 is driven to slide, and the extended length of the threaded rod 503 can be adjusted to adapt to cups with different inner diameters.

[0026] Specifically, a limiting groove 505 is formed at the top of the threaded rod 503, and a limiting rod 506 is fixedly installed at the bottom of the semi-gear rotating block 501. The limiting rod 506 is slidably inserted into the limiting groove 505.

[0027] In this embodiment, through the provided limiting rod 506 and limiting groove 505, the threaded rod 503 can be limited during sliding, so that it will only slide under the drive of the threaded collar 507 and will not rotate, facilitating adjustment by the staff.

[0028] Specifically, a spring 604 is fixedly installed between the bottom of the sliding rod 601 and the bottom inner wall of the sliding groove 403.

[0029] In this embodiment, when the sliding rod 601 is pressed down by the cup, the spring 604 will be compressed simultaneously. After the coating is completed and the cup is removed, the spring 604 will release and push the sliding rod 601 and the four rack bars 603 to slide upward, driving the four support assemblies 5 to reset, facilitating the next use.

[0030] The above is only a preferred embodiment of the present invention, and it is not a limitation of the present invention in other forms. Any person skilled in the art may use the disclosed technical content to make changes or modifications into equivalent embodiments with equivalent changes. However, any simple modification, equivalent change, and modification made to the above embodiments based on the technical essence of the present invention without departing from the technical solution content of the present invention still belong to the protection scope of the technical solution of the present invention.
