[0002] Vacuum coating equipment includes a vacuum chamber and a rotating frame inside the vacuum chamber for suspending workpieces to be coated. In order to ensure uniform coating of each workpiece, the rotating frame itself and each clamping rod on the rotating frame need to rotate continuously inside the vacuum chamber.

[0003] Currently, the rotating frames of existing coating equipment are basically fixedly installed inside a vacuum chamber. During coating, workpieces are placed one by one on the frame, and then removed sequentially after coating. Although the operation is simple and convenient, the limited space within the vacuum chamber makes it difficult to disassemble, maintain, and clean the frame later, resulting in low practicality and hindering long-term use and widespread adoption. Therefore, those skilled in the art have provided a convenient vacuum coating rotating frame structure to solve the problems mentioned in the background section. Utility Model Content

[0004] To address the shortcomings of existing technologies, this utility model provides a convenient vacuum coating rotating frame structure, which solves the problem mentioned in the background technology that the limited space inside the vacuum chamber makes it difficult to disassemble, maintain, and clean the rotating frame later, resulting in low practicality in actual use and hindering long-term use and promotion.

The top plate is fixedly connected to the rotating shaft by a screw.

[0008] As a further technical solution of this utility model, the power assembly includes a gear one located inside the annular groove and fixedly installed on the outer peripheral surface of the rotating shaft.

[0011] This invention provides a convenient vacuum coating rotating frame structure, which has the following advantages compared with the prior art:

[0012] 1. This design provides a convenient vacuum coating rotating frame structure. The entire rotating frame structure can be disassembled and separated through the top plate, round holes, slots, inserts, and fixed base plate.

[0025] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the protection scope of the present utility model.

[0026] Please see Figure 1-6This utility model provides a convenient vacuum coating rotating frame structure: it includes a fixed base plate 1, an annular groove 101 is formed at the center of the outer top surface of the fixed base plate 1, a rotating shaft 102 is rotatably mounted at the center of the inner bottom surface of the annular groove 101, a circular plate 103 is rotatably connected to the outer top surface of the fixed base plate 1 above the annular groove 101, connecting rods 104 arranged in a circular array are rotatably mounted on the outer top surface of the circular plate 103, and support rods 105 are provided on the outer top surface of each of the connecting rods 104. Suspension frames 106 arranged in a vertical linear array are sleeved on the outer circumferential surface of the support rods 105, and a top plate 107 is rotatably mounted on the outer top surface of the support rods 105. A circular block 3 is fixedly installed on the outer top surface of the connecting rod 104, and a slot 301 is provided at the center of the outer top surface of the circular block 3. At the same time, a circular block 302 is fixedly installed on the outer bottom surface of the four support rods 105. An insert 303 that matches the slot 301 is fixedly installed at the center of the outer bottom surface of the four circular blocks 302. The insert 303 is engaged in the inner side of the slot 301. A circular hole 304 distributed in a circumferential array is provided on the outer bottom surface of the top plate 107. One end of the four support rods 105 is rotatably sleeved in the inner side of the circular hole 304. At the same time, one end of the rotating shaft 102 extends through the circular plate 103 to the outer top surface of the top plate 107. The top plate 107 is fixedly connected to the rotating shaft 102 by a screw. During disassembly and maintenance, first loosen the bolts to release the fixed relationship between the top plate 107 and the rotating shaft 102. Then, remove the top plate 107 to separate one end of the support rod 105 from the round hole 304. Next, pull the support rod 105 to separate the insert block 303 from the slot 301. Then, remove the support rod 105 in sequence. Finally, loosen the screw in the threaded hole on the fixed base plate 1 to remove the entire rotating part. This facilitates careful cleaning and maintenance, extends the service life of the equipment, and enhances its practicality.

[0027] The annular groove 101 is equipped with a power assembly 2 for rotating the support rod 105. The power assembly 2 includes a gear 201 located inside the annular groove 101 and fixedly installed on the outer circumferential surface of the rotating shaft 102. One end of the four connecting rods 104 extends through the circular plate 103 into the annular groove 101 and is also fixedly installed on the outer circumferential surface. The gear 201 and the four gears 202 are meshed with each other. One end of the rotating shaft 102 extends to the outside of the fixed base plate 1 and is fixedly connected to the output end of the drive motor 203 fixedly installed on the outer bottom surface of the fixed base plate 1. An internal gear ring 204 is fixedly installed on the inner circumferential side wall of the annular groove 101. The internal gear ring 204 is meshed with the four gears 202. The drive motor 203 is controlled and started to drive the rotating shaft 102 to drive the gear 201 to rotate. Under the meshing transmission characteristics of the gears, the four gears 202 are driven to rotate around the internal gear ring 204, so that the support rod 105 rotates on its own axis and revolves along the annular groove 101, thereby improving the coating effect of the workpiece and further improving its practicality.

[0028] The outer surfaces of the four support rods 105, corresponding to the suspension brackets 106, are provided with vertically linearly arranged limiting holes 4. The outer surfaces of several suspension brackets 106, corresponding to the limiting holes 4, are provided with through-hole limiting holes 401. The limiting holes 4 and 401 are fixed together by bolts. Tightening the bolts allows them to be inserted into the inner side of the limiting holes 4 along the limiting holes 401, facilitating the assembly and disassembly of the suspension brackets 106 as needed. The operation is simple and convenient.

[0029] The working principle of this utility model is as follows: When in use, the drive motor 203 is started to drive the rotating shaft 102 to drive the circular plate 103 and the top plate 107 to rotate, so that the workpiece to be coated on the suspension frame 106 can be rotated and coated in the vacuum chamber of the coating equipment.

[0030] At the same time, when the rotating shaft 102 rotates, it synchronously causes the first gear 201 to drive the four second gears 202 to rotate around the internal gear ring 204 on the annular groove 101, so that the workpiece on the support rod 105 can revolve along the annular groove 101 while also spinning, thereby improving the coating effect on the workpiece.

[0031] Meanwhile, after the coating is completed, the bolts are turned to remove the top plate 107 and one end of the support rod 105 is separated from the round hole 304. Then, the support rod 105 is pulled to separate the insert block 303 from the slot 301, so that the support rod 105 can be removed in sequence.

[0032] Finally, by turning the screw in the threaded hole on the fixed base plate 1, the entire rotating part can be removed for careful cleaning and maintenance.

[0033] The above description is merely a preferred embodiment of this utility model. It should be noted that those skilled in the art can make various improvements and modifications without departing from the principles of this utility model, and these improvements and modifications should also be considered within the scope of protection of this utility model. Structures, devices, and operating methods not specifically described or explained in this utility model are implemented according to conventional methods in the art, unless otherwise specified or limited.
