Description

Technical Field

[0001] This utility model relates to the field of vacuum coating fixture technology, specifically a vacuum coating fixture that adapts to the shape of a workpiece. Background Technology

[0002] Vacuum coating is a process that uses vacuum technology to form a thin film on the surface of a material. This process is widely used in various fields, such as optics, electronics, automobiles, and decoration, to achieve different functional requirements. Vacuum coating refers to the technique of depositing metallic or non-metallic materials in the form of gas or vapor onto the surface of a substrate in a vacuum environment through physical or chemical means to form a thin film. Vacuum coating is an important surface treatment technology that can endow materials with a variety of advanced functions. Its high performance and wide application make it occupy an important position in modern industry.

[0003] An investigation revealed that a Chinese utility model patent (publication number: CN212223091U) discloses a vacuum coating fixture, comprising a base with a threaded hole on its upper surface, a base plate on top of the base, a protrusion fixedly connected to the edge of the outer surface of the base plate, a shelf on top of the base plate, a slot on the bottom edge of the shelf, a sliding groove on the inner side wall of the shelf, a sliding rod movably connected to the surface of the sliding groove, a cylinder fixedly connected to the surface of the sliding rod, a clamping spring on top of the sliding rod, and a circular hole at the center of the surface of the clamping spring. This utility model has the following advantages: the vacuum coating fixture is convenient to clamp, has a simple structure, and can be quickly installed and disassembled; it also allows for batch vacuum coating of covers.

[0004] While the aforementioned patented design, through its structural configuration, makes vacuum coating fixtures easy to grip, simple in structure, and quick to install and disassemble, and allows for batch vacuum coating of covers, it is not convenient to adaptively adjust the fixture according to the size of the workpiece during vacuum coating. If the fixture cannot be adjusted according to different workpiece shapes, it may not be applicable to workpieces of various sizes and shapes, thus limiting the fixture's versatility. For production lines that require frequent workpiece changes, fixed fixtures will reduce production efficiency, requiring a long adjustment time each time a workpiece is changed, thereby reducing work efficiency.

[0005] Therefore, this invention provides a vacuum coating fixture that adapts to the shape of the workpiece to solve the above problems. Utility Model Content

One end of the adjusting rod 4 is rotatably connected to a clamping plate 5 via a rotating shaft A, and one end of the clamping plate 5 is rotatably connected to a fixing rod 6 via a rotating shaft B. An adsorption mechanism is inserted into the outer surface of the fixing rod 6. An air extraction hole is opened on the surface of the clamping plate 5, and a reinforcement mechanism is fixedly connected inside the air extraction hole. When clamping for vacuum coating, the clamping mechanism can adaptively clamp the workpiece according to its shape. Adjusting the clamping according to the workpiece shape can achieve a closer contact, reduce the movement of the workpiece during the coating process, ensure stability, effectively prevent film peeling during the coating process, extend the service life of the film, and improve product quality. When the placement plate 2 is raised and lowered, it drives the rotating component A 3 to rotate and adjust the adjusting rod 4. The adjusting rod 4 drives the clamping plate 5 to extend and retract within the fixing rod 6, which facilitates the adjustment of the opening and closing angle of the clamping plate 5.

[0030] The lifting mechanism includes a drive motor 7. The output end of the drive motor 7 is splinedly connected to a sleeve 8. The sleeve 8 is threadedly connected to a threaded rod 9. One end of the threaded rod 9 is rotatably connected to a plug block 10 via a bearing. The upper surface of the plug block 10 is fixedly connected to the bottom of the placement plate 2. When clamping the vacuum coating, the drive motor 7 is started according to the shape and size of the vacuum coating workpiece. When the drive motor 7 rotates, it drives the threaded rod 9 to move up and down inside the sleeve 8. The threaded rod 9 drives the plug block 10 and the placement plate 2 to move up and down inside the support plate 1.

[0031] The adsorption mechanism includes a vacuum pump 11, one end of which is fixedly connected to an air extraction pipe 12. Both ends of the air extraction pipe 12 are fixedly connected to a transmission pipe 13. The outer surface of the transmission pipe 13 is inserted into the inside of the clamping plate 5. When clamping, the vacuum pump 11 is started to extract air from the air extraction pipe 12, which flows from the transmission pipe 13 into the telescopic pipe 14.

[0036] Specifically, when clamping the vacuum coating, the drive motor 7 is started according to the shape and size of the workpiece to be vacuum coated. When the drive motor 7 rotates, it drives the threaded rod 9 to move up and down inside the sleeve 8. The threaded rod 9 drives the insertion block 10 and the placement plate 2 to move up and down inside the support plate 1. When the placement plate 2 moves up and down, it drives the A rotating component 3 to rotate and adjust the adjusting rod 4.
