Abstract
Description
Technical Field
[0001] This utility model relates to the field of coating technology, specifically a coating thickness control device. Background Technology
[0002] Vacuum coating equipment is a type of device that needs to operate in a high vacuum environment. It is mainly used to form thin film coatings on the surface of materials. These devices are widely used in fields such as optics, electronics, and mechanics to improve the performance and lifespan of products. Vacuum coating technology mainly includes two categories: evaporation and sputtering. The evaporation of the heat source material is achieved by heating the material and then condensing it on the substrate to form a thin film.
[0003] However, although most existing vacuum coating equipment has the function of thickness control, there are still many problems. For example, the inability to stably fix the workpiece is one of the problems. As a result, the workpiece is usually fixed by being sleeved on a rod. This fixing method will cause the workpiece to be unstable and there is a probability that the workpiece will fall off. Moreover, the fixing method of sleeved on the rod can usually only meet the requirements for fixing ring-shaped workpieces, such as wheel hubs.
[0004] Therefore, this utility model provides a coating thickness control device to solve the above problems. Utility Model Content

[0006] This utility model provides a coating thickness control device, which aims to solve the problem that although most of the existing vacuum coating equipment has the function of thickness control, it cannot stably fix the workpiece, which will cause the workpiece to fall. In addition, the fixing method of sleeve on the rod can usually only meet the problem of fixing ring-shaped workpieces.
[0007] (II) Technical Solution
[0008] To achieve the above objectives, this utility model provides the following technical solution: a coating thickness control device, comprising a coating equipment body, a coating rod rotatably connected inside the coating equipment body, a plurality of connecting strips fixedly connected to the outer surface of the coating rod, a rotating rod rotatably connected inside the connecting strips, a connecting plate fixedly connected to the end of the rotating rod away from the connecting strips, a telescopic rod fixedly connected to the outer wall of the connecting plate, a fixed plate fixedly connected to the end of the telescopic rod away from the connecting plate, a spring fixedly connected to the outer wall of the connecting plate, the end of the spring away from the connecting plate being fixedly connected to the outer wall of the fixed plate, the telescopic rod being inserted through the inner ring of the spring, a force-bearing block fixedly connected to the outer wall of the fixed plate, a placement plate being slidably embedded inside the connecting plate, and a pressing block in contact with the force-bearing block fixedly connected to the top of the placement plate.
[0009] As a preferred technical solution of this application, the outer wall of the connecting plate is provided with a through hole for the force-bearing block to move, and the outer wall of the force-bearing block and the extrusion block are arc-shaped to fit each other.

[0012] As a preferred technical solution of this application, a threaded rod is rotatably connected to the inner wall of the base, and a motor for driving the threaded rod to rotate is provided on the outer wall of the base.

[0015] (III) Beneficial Effects
[0016] This invention utilizes a placement plate, a telescopic rod, a spring, a pressing block, and a force-bearing block. When the placement plate is pulled outward, the pressing block contacts and presses against the force-bearing block. When the force-bearing block is pressed, the telescopic rod moves the fixing plate outward, allowing the placement plate to move smoothly for workpiece placement. When a workpiece is placed on the placement plate, pushing the plate inward causes the pressing block to press against the force-bearing block, moving the fixing plate outward and restoring the placement plate to its original position. The fixing plate also uses the spring's elasticity to secure the workpiece. This device provides stable workpiece fixation, preventing instability caused by simply attaching the workpiece to the rod. Furthermore, this fixing method can accommodate workpieces of various shapes. Attached Figure Description

[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0025] This utility model provides a coating thickness control device, such as... Figure 1-5 As shown, the vacuum coating equipment includes a coating equipment body 1. A coating rod 2 is rotatably connected inside the coating equipment body 1. Multiple connecting strips 3 are fixedly connected to the outer surface of the coating rod 2. A rotating rod 4 is rotatably connected inside the connecting strips 3. A connecting plate 5 is fixedly connected to the end of the rotating rod 4 away from the connecting strips 3. A telescopic rod 6 is fixedly connected to the outer wall of the connecting plate 5. A fixing plate 7 is fixedly connected to the end of the telescopic rod 6 away from the connecting plate 5. A spring 8 is fixedly connected to the outer wall of the connecting plate 5. The end of the spring 8 away from the connecting plate 5 is fixedly connected to the outer wall of the fixing plate 7. The telescopic rod 6 is inserted into the inner ring of the spring 8. A force-bearing block 9 is fixedly connected to the outer wall of the fixing plate 7. A placement plate 10 is slidably embedded inside the connecting plate 5. An extrusion block 11 that contacts the force-bearing block 9 is fixedly connected to the top of the placement plate 10.
[0026] Specifically, when a workpiece needs to be placed on the placement plate 10 for coating, the placement plate 10 is first pulled outward. This outward movement causes the two pressing blocks 11 to contact the two force-bearing blocks 9. When the two force-bearing blocks 9 are pressed by the pressing blocks 11, they respectively drive the fixing plates 7 and use the telescopic rod 6 to move them away from each other, allowing the placement plate 10 to continue moving outward. When the workpiece is placed on the placement plate 10, the placement plate 10 is pushed inward. This causes the two pressing blocks 11 to contact the two force-bearing blocks 9 again and press them, causing the two fixing plates 7 to move away from each other again. This prevents the workpiece from being blocked by the fixing plates 7 and allows it to continue moving inward to the appropriate position. When the pressing blocks 11 lose pressure on the force-bearing blocks 9, the two fixing plates 7 can use the elastic force of the spring 8 to move closer together, thus securing the workpiece on the placement plate 10 and preventing it from falling. This stable fixation can accommodate various shapes.
[0027] The outer wall of the connecting plate 5 is provided with a through hole 12 for the force-bearing block 9 to move. The outer wall of the force-bearing block 9 and the extrusion block 11 are arc-shaped and adapted.
[0028] A gear 13 is fixedly connected to the outer surface of the rotating rod 4, and a toothed ring 14 that meshes with the gear 13 is fixedly connected to the inner wall of the coating equipment body 1.
[0029] Specifically, the outer walls of the force-bearing block 9 and the extrusion block 11 are arc-shaped to ensure better compatibility when they come into contact. This ensures that the extrusion block 11 can press the force-bearing block 9, preventing motion interference between the extrusion block 11 and the force-bearing block 9, which would prevent the force-bearing block 9 from driving the fixed plate 7 to move normally. The through hole 12 provides space for the force-bearing block 9 to move. Thus, when the two extrusion blocks 11 press against the two force-bearing blocks 9, the two force-bearing blocks 9 can drive the fixed plate 7 to work away from each other without being restricted by the connecting plate 5. This ensures that the distance between the two fixed plates 7 is sufficient for the placement of the workpiece, preventing interference between the fixed plate 7 and the workpiece due to the restriction of the connecting plate 5. Furthermore, when the coating rod 2 drives the workpiece on the placement plate 10 to rotate and form a coating, the gear 13 that meshes with the toothed ring 14 can drive the rotating rod 4 to rotate, so that the placement plate 10 can be rotated. This improves the overall coating coverage and coating effect of the workpiece.
[0030] A base 15 is fixedly connected to the bottom of the coating equipment body 1, and a telescopic cover 16 is fixedly connected to the top of the base 15.
[0031] A threaded rod 17 is rotatably connected to the inner wall of the base 15, and a motor 18 for driving the threaded rod 17 to rotate is provided on the outer wall of the base 15.
[0032] The outer surface of the threaded rod 17 is threadedly connected to a threaded sleeve 19, and the outer surface of the threaded sleeve 19 is fixedly connected to the outer surface of the telescopic cover 16.
[0033] Specifically, when the coating equipment body 1 is not in use, the motor 18 can be started, causing the output shaft of the motor 18 to drive the threaded rod 17 to rotate. The threaded sleeve 19, which is threaded with the threaded rod 17, will move the telescopic cover 16 upward due to the rotation of the threaded rod 17. The telescopic cover 16 will continuously move upward to surround the coating equipment body 1, preventing external dust from entering the coating equipment body 1 and affecting its coating performance when it is not in use. At the same time, it can also prevent the coating equipment body 1 from being damaged by external collisions to a certain extent, thereby improving the performance and service life of the coating equipment body 1.
[0034] A limiting block 20 is fixedly connected to the outer surface of the threaded sleeve 19, and a limiting hole 21 for the limiting block 20 to slide is provided on the outer wall of the base 15.
[0035] Specifically, the limiting hole 21 allows the limiting block 20 to have room to move, so that when the threaded sleeve 19 is rotated by the threaded rod 17 by the cooperation of the limiting block 20 in the limiting hole 21, it can move smoothly, preventing the threaded sleeve 19 from rotating synchronously with the threaded rod 17 without a limiting point. This ensures that the threaded sleeve 19 can drive the telescopic cover 16 to move upward to a suitable position to surround and protect the coating equipment body 1.
[0036] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
