Description

Technical Field

[0001] This utility model relates to the field of vacuum coating technology, specifically to an adjustable-angle vacuum coating rotating device. Background Technology

[0002] A vacuum coating rotary device is a device used to uniformly rotate a workpiece during coating treatment in a vacuum environment. Its main function is to ensure that the coating material is deposited evenly on the workpiece surface by rotating the workpiece uniformly, avoiding problems such as uneven coating thickness and inconsistent color, thus improving coating quality and product consistency. For some workpieces with complex shapes, the rotary device can enable the coating material to reach all parts of the workpiece, including areas that are difficult to coat directly, such as depressions and protrusions, achieving all-round coating. It is widely used in many fields such as optics, electronics, automobiles, and decoration.

[0003] Traditional vacuum coating rotary apparatuses can only adjust the planar angle of the workpiece, not its vertical angle, which presents several shortcomings in practical applications. For example, coating uniformity is poor. For workpieces with complex curved surfaces or special structures, planar rotation alone is insufficient to ensure uniform coating material coverage of vertical surfaces, uneven surfaces, etc. For optical lenses with grooves or protrusions, the inability to adjust the angle of the vertical surface leads to insufficient coating material deposition, resulting in inconsistent light transmittance across different areas of the lens and affecting optical performance. Furthermore, it results in poor process adaptability. Different coating processes have specific requirements for workpiece angles. Some coating technologies require the workpiece to be at a specific vertical angle to achieve directional deposition of atoms or molecules, forming a high-quality thin film. Traditional apparatuses cannot meet these process requirements, limiting the application of advanced coating technologies and hindering the preparation of high-performance thin film materials. Utility Model Content

[0004] One of the technical problems that this application aims to solve is that traditional vacuum coating rotary devices can only adjust the plane angle of the workpiece to be coated, but cannot adjust the vertical angle of the workpiece to be coated, which has many shortcomings in practical use.

[0005] To address the aforementioned technical problems, this application provides an adjustable-angle vacuum coating rotary device, comprising a processing box and a base. A movable groove is formed in the middle of the lower end of the processing box, and a mounting groove is formed in the middle of the upper end of the processing box. A cylinder is fixedly mounted on one side of the middle of the mounting groove, and a gear plate is fixedly mounted on the output end of the cylinder. A rotating shaft is rotatably mounted in the middle of one side of the mounting groove, and a half-gear is fixedly mounted on the lower end of the rotating shaft. A base plate is rotatably mounted on the upper end of the rotating shaft. A bracket is fixedly mounted on one side of the middle of the rotating shaft, and a motor is fixedly mounted on one end of the bracket. A transmission gear is fixedly mounted on the output end of the motor, and an internal gear ring is fixedly mounted on the outer side of the middle of the lower end of the base plate.

[0022] 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.

[0023] Example 1: Please refer to Figure 1-4This utility model provides a technical solution: an adjustable angle vacuum coating rotary device, including a processing box 1 and a base 11. A movable groove 23 is provided in the middle of the lower end of the processing box 1, and a mounting groove 2 is provided in the middle of the upper end of the processing box 1. A cylinder 21 is fixedly installed on one side of the middle of the mounting groove 2. A toothed plate 22 is fixedly installed at the output end of the cylinder 21. A rotating shaft 24 is rotatably installed in the middle of one side of the mounting groove 2. A half gear 25 is fixedly installed at the lower end of the rotating shaft 24. A base plate 26 is rotatably installed at the upper end of the rotating shaft 24. A bracket 28 is fixedly installed on one side of the middle of the rotating shaft 24. A motor 29 is fixedly installed at one end of the bracket 28. A transmission gear 30 is fixedly installed at the output end of the motor 29. An internal gear ring 27 is fixedly installed on the outer side of the middle of the lower end of the base plate 26. The movable groove 23 and the mounting groove 2 are connected. The middle of the upper end of the rotating shaft 24 is located in the middle of the movable groove 23. The toothed plate 22 and the half gear 25 mesh with each other. The transmission gear 30 and the internal gear ring 27 mesh with each other.

[0024] In this embodiment, the cylinder 21 pushes the toothed plate 22, which meshes with the half gear 25, driving the rotating shaft 24 to rotate. This allows the base plate 26 and the workpiece mounted on it to be adjusted within a certain angle range, meeting the angle requirements of different coating processes. Compared with traditional fixed-angle rotating devices, this greatly improves the flexibility and applicability of the device. The motor 29 drives the base plate 26 to rotate through the meshing of the transmission gear 30 and the internal gear ring 27. Compared with some traditional belt or chain drives, this transmission method has higher transmission accuracy and stability, ensuring that the workpiece remains stable during rotation, which is beneficial to improving the uniformity and quality of the coating. The cylinder 21, gear plate 22, half gear 25, rotating shaft 24, motor 29, transmission gear 30, and internal gear ring 27 are reasonably installed in the mounting slot 2 and movable slot 23 of the processing box 1. The overall structure is compact and occupies little space. At the same time, the connection and fit between the components are tight, which is conducive to stable operation in a vacuum environment and reduces the possibility of affecting the coating effect due to loosening or shaking of the components. The movement of the cylinder 21 and motor 29 can be precisely controlled by the control system, which can accurately realize angle adjustment and rotation speed control. It is convenient for operators to set and adjust according to different coating requirements, thereby improving the automation level and production efficiency of the equipment.

[0025] Example 2: As Figure 1-4As shown, the processing box 1 is fixedly installed on the upper end of the base 11. Doors 12 are hinged and mounted on both sides of the middle of one end of the processing box 1. Vacuum tubes 15 are fixedly connected to both sides of the middle of the upper end of the processing box 1. A coating nozzle 16 is fixedly installed in the middle of the upper end of the processing box 1. Door handles 14 are fixedly installed on one end of each of the two doors 12. Observation windows 13 are provided in the middle of each of the two doors 12. A horizontal plate 17 is fixedly installed on one side of the upper end of the internal gear ring 27. A rotating part is mounted in the middle of the horizontal plate 17. A double-acting screw 18 has one end that passes through a horizontal plate 17 and is fixedly connected to a handle 19. Both sides of the middle of the horizontal plate 17 are slidably engaged with clamping plates 20. The middle part of one end of the clamping plates 20 is threadedly connected to the double-acting screw 18. A limiting groove 33 is opened in the middle of the lower part of one end of the mounting groove 2. A support rod 31 is fixedly installed below one end of the toothed plate 22. Both sides of the lower middle part of the support rod 31 are rotatably mounted with rotating wheels 32. The support rod 31 is slidably engaged through the rotating wheels 32 and the limiting groove 33.

[0026] In this embodiment, the chamber door 12 is hinged and equipped with a handle 14, facilitating the opening and closing of the processing chamber 1 by operators, and making it convenient to place and remove workpieces and to inspect and maintain internal components. The observation window 13 in the middle allows operators to observe the coating process inside the chamber in real time without disrupting the vacuum environment, promptly identify abnormalities, and adjust process parameters. The vacuum tube 15 is connected to the processing chamber 1, enabling rapid and efficient extraction of air from the chamber to establish a stable vacuum environment, providing a foundation for high-quality coating. The coating nozzle 16 is fixedly installed in the upper middle part of the processing chamber 1, enabling precise coating spraying of workpieces. Combined with the multi-angle adjustment and stable rotation of the rotating device, the coating material can be evenly covered on the workpiece surface, improving coating quality and efficiency. At the same time, the fixed installation method ensures the stability of the nozzle position. To avoid coating deviations caused by shaking, the bidirectional lead screw 18 on the horizontal plate 17 is designed in conjunction with the clamping plate 20. By rotating the handle 19, the bidirectional lead screw 18 is driven to rotate, causing the clamping plates 20 on both sides to move in opposite directions. The spacing can be flexibly adjusted to accommodate workpieces of different sizes and specifications, achieving firm clamping and preventing the workpiece from shifting or shaking during the coating rotation process, thus ensuring consistent coating results. The toothed plate 22 is slidably engaged with the limiting slide groove 33 through the support rod 31 and the rotating wheel 32, providing stable guidance and support for the movement of the toothed plate 22. When the cylinder 21 drives the toothed plate 22 to move, the rotating wheel 32 rolls within the limiting slide groove 33, reducing frictional resistance and making the movement of the toothed plate 22 smoother and more stable. This ensures the accuracy and stability of the angle adjustment of the rotating shaft 24, preventing the shaking of the toothed plate 22 from affecting the operating accuracy of the device.

[0027] like Figure 1-4As shown, before the coating operation, the handle 19 is rotated according to the size of the workpiece to be coated. The handle 19 drives the bidirectional lead screw 18 to rotate in the horizontal plate 17. Since the middle part of one end of the clamping plate 20 is threadedly connected to the bidirectional lead screw 18, and the clamping plate 20 slides and engages on both sides of the middle of the horizontal plate 17, the rotation of the bidirectional lead screw 18 will cause the two clamping plates 20 to move towards or away from each other along the length of the horizontal plate 17. In this way, workpieces of different sizes can be clamped between the two clamping plates 20. Then, the processing box 1 is evacuated to a vacuum state through the vacuum tube 15. The vacuum tube 15 is connected to both sides of the middle of the upper end of the processing box 1. This design allows the air in the processing box 1 to be uniformly extracted, quickly establishing and maintaining a stable vacuum environment. In the vacuum environment, the coating nozzle 16 is activated, and the coating nozzle 16 sprays the coating material in a specific manner. At this time, the workpiece is driven by the rotating device to adjust its angle and rotate. The coating material is uniformly deposited on the surface of the workpiece in the vacuum environment, forming a high-quality coating layer. Operators can observe the coating process through the observation window 13 in the middle of the door 12 to promptly identify problems that arise, such as the distribution of the coating material and the rotation state of the workpiece, and make corresponding adjustments based on the actual situation. Furthermore, the processing box 1 has the door 12 mounted on a hinge, and a handle 14 is provided on the door 12 for easy access before and after coating to load and unload workpieces and perform equipment maintenance. When angle adjustment is required during coating, the cylinder 21 can be activated, its output end pushing the toothed plate 22 to move within the mounting slot 2. Because the toothed plate 22 meshes with the half gear 25, the linear motion of the toothed plate 22 is converted into the circular motion of the half gear 25, which drives the rotating shaft 24 to rotate within the movable slot 23. Since the upper end of the rotating shaft 24 is rotatably connected to the base plate 26, the base plate 26 rotates with the rotating shaft 24, thus achieving vertical angle adjustment of the workpiece mounted on the base plate 26. After the motor 29 is started, its output end drives the transmission gear 30 to rotate. The transmission gear 30 meshes with the internal gear ring 27 fixed on the outer side of the middle part of the lower end of the base plate 26. The rotation of the transmission gear 30 drives the internal gear ring 27 and the entire base plate 26 to rotate in a plane around the axis of the rotating shaft 24, thereby realizing the angle of the workpiece around the axis of the rotating shaft 24 in the plane direction, so that the coating material sprayed by the coating nozzle 16 can evenly cover the surface of the workpiece and ensure the uniformity of the coating.
