Description

Technical Field

[0001] This utility model relates to the field of vacuum coating carrier technology, specifically a rotatable vacuum coating carrier. Background Technology

[0002] Fixtures are widely used in machining and coating processes. Their core function is to reliably fix and precisely position and stably support components during processing. Specifically in the field of coating equipment, fixtures are mainly used to support and fix components to be coated, ensuring they maintain a preset position during the coating process, thereby meeting the positioning accuracy requirements of the coating process. Depending on the application scenario, fixtures can be divided into general-purpose fixtures and special-purpose fixtures. General-purpose fixtures are suitable for clamping various component sizes, while special-purpose fixtures are customized for the structural characteristics of specific components. During the operation of the coating machine, the fixture not only fixes the component but also needs to dynamically adjust the component in accordance with the coating process requirements—for example, by using a drive device to synchronously rotate the fixture and the component to be coated, so that the surface of the component can evenly receive the coating material during the coating process, avoiding uneven film distribution caused by a fixed posture.

[0003] However, most common fixture rotation methods in existing technologies employ a revolution motion mode, where the fixture and the part to be coated rotate as a whole around a single axis. When the part to be coated has a planar structure or a simple curved surface, this motion mode can achieve a basically uniform distribution of the film layer through continuous displacement of the part surface. However, when the part surface has a concave structure or a complex curved surface, relying solely on revolution motion is insufficient to ensure effective film deposition. This is because concave areas are easily blocked by their own structure during revolution, preventing these areas from fully contacting the coating material, thus creating areas without coating or with insufficient film thickness. Ultimately, this affects the overall uniformity of the coating effect and the stability of product quality. Utility Model Content

[0004] The purpose of this invention is to provide a rotatable vacuum coating carrier to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, the present invention provides the following technical solution: a rotatable vacuum coating carrier, including a vacuum coating equipment, a door hinged to the open end of the vacuum coating equipment, a rotating component inside the vacuum coating equipment, a fixed plate inside the vacuum coating equipment, an mounting plate inside the fixed plate via a self-rotating mechanism, and a positioning mechanism below the mounting plate and on the rotating component.

[0006] Preferably, in order to rotate the workpiece and ensure sufficient uniformity of coating, the rotating component includes a motor installed on the vacuum coating equipment. A rotating shaft is fixedly installed at the output end of the motor. The bottom end of the rotating shaft is rotatably connected to the bottom end of the vacuum coating equipment through a bearing seat. A turntable is also installed on the rotating shaft.

[0007] Preferably, while revolving around the sun, the workpiece can also rotate on its own axis to ensure that the coating is fully uniform and avoid dead corners. The rotation mechanism includes a gear ring set in the fixed plate, and a gear is meshed in the gear ring. The bottom end of the gear is fixedly connected to the mounting plate through a connecting column.

[0008] Preferably, in order to prevent gear slippage and ensure rotation within the gear ring, limit plates are provided on both the fixed plate and below the fixed plate, and the limit plates are matched with the gears.

[0009] Preferably, in order to facilitate the clamping and fixing of the workpiece, the positioning mechanism includes an electric push rod set under the mounting plate, a dynamic pressure plate set at the output end of the electric push rod, and a fixed support plate rotatably set on the turntable via a rotating shaft, with the fixed support plate corresponding to the dynamic pressure plate one by one.

[0010] Preferably, in order to ensure a firm clamping, clamping plates are provided on both the fixed support plate and the lower part of the dynamic pressure plate, and protrusions are provided on the end faces of the clamping plates that are close to each other.

[0011] Preferably, an observation window is embedded in the door to facilitate observation of the internal situation.

[0012] Compared with the prior art, the beneficial effects of this utility model are: (1) The self-rotation mechanism adopts a gear and gear meshing transmission structure. The gear is fixed in the fixed plate, and the gear meshes with the gear. The bottom end of the gear is fixedly connected to the mounting plate through the connecting column. The revolution motion makes the workpiece surface receive the coating material as a whole. The self-rotation motion eliminates the structural obstruction of the recessed area by the rotation of the workpiece itself, ensuring uniform coverage of the film layer. (2) The positioning mechanism adopts a raised clamping plate structure to enhance the clamping reliability. It can stably fix the workpiece during the dynamic process of revolution and rotation, avoid the workpiece falling off or shifting during the coating process, and ensure the stability of the film quality. Through motion mode optimization and structural reliability improvement, it is suitable for vacuum coating processing of various curved surfaces and complex structure workpieces, enhances the uniformity, stability and operation convenience of the coating process, and ultimately improves product quality and production efficiency.

Detailed Implementation

[0015] 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.

[0016] Please see Figures 1-4 This utility model provides an embodiment of a rotatable vacuum coating carrier, including a vacuum coating device 11, mainly composed of a vacuum system (to create the low-pressure environment required for coating), a coating chamber system (the coating chamber is the core space where the workpiece and the film material interact), a temperature control component (to regulate the temperature of the workpiece / film material), and a film monitoring system (to ensure that the film quality meets the standards), etc. The vacuum coating equipment 11 is configured according to actual processing needs. It is a relatively mature technology and will not be described in detail here. The open end of the vacuum coating equipment 11 is hinged with a door 12, which can be connected by hinges or other hinges. The end of the door 12 away from the hinge is provided with a handle for easy opening and closing. There is also an observation window 13 on the inner front of the door 12 for easy observation of the internal coating condition. This is a relatively mature technology and will not be described in detail here. In order to facilitate the rotation of the workpiece during processing and ensure sufficient and uniform coating, the vacuum coating equipment 11 is provided with a rotating component. The rotating component includes a motor 15 installed on the vacuum coating equipment 11. The output end of the motor 15 is fixedly provided with a rotating shaft 16 through a coupling. The bottom end of the rotating shaft 16 is rotatably connected to the bottom end of the vacuum coating equipment 11 through a bearing seat. A turntable 14 is also provided on the rotating shaft 16.

[0017] Please see Figures 1-4To facilitate workpiece clamping and positioning, and to ensure uniform coating and avoid dead zones during both revolution and rotation, the vacuum coating equipment 11 includes a fixed plate 21. A mounting plate 26 is mounted within the fixed plate 21 via a rotation mechanism. Positioning mechanisms are located below the mounting plate 26 and on the rotating assembly. The rotation mechanism includes a gear ring 23 within the fixed plate 21, with a gear 24 meshing within it. The bottom end of the gear 24 is fixedly connected to the mounting plate 26 via a connecting post 25. Limiting plates 22 are located both above and below the fixed plate 21, matching the gear 24 and limiting its movement to prevent vertical displacement. The upward offset ensures that the gear 24 meshes and rotates with the gear ring 23. The number of gears 24 and positioning mechanisms can be three, four or five sets, preferably four sets, so that four sets of workpieces can be positioned and coated at the same time. Other numbers can also be set according to actual conditions. The positioning mechanism includes an electric push rod 27 set under the mounting plate 26. The output end of the electric push rod 27 is provided with a dynamic pressure plate 35. A fixed support plate 31 is rotatably set on the turntable 14 through a rotating shaft 32. The fixed support plate 31 and the dynamic pressure plate 35 correspond one-to-one. Clamping plates 33 are provided on the fixed support plate 31 and under the dynamic pressure plate 35. The end faces of the clamping plates 33 that are close to each other are provided with protrusions 34, which can facilitate the clamping and fixing of the workpieces and facilitate subsequent rotation coating processing.

[0018] Working principle: In use, the workpiece to be processed is placed on the clamping plate 33 of the fixed support plate 31. The electric push rod 27 extends, causing the moving pressure plate 35 to move downward. At this time, the accessory clamping plate 33 and the protrusion 34 clamp and fix the workpiece. Then, the door 12 is closed, and the motor 15 works, causing the rotating shaft 16 to rotate. The turntable 14 rotates accordingly, and the gear 24 rotates in the gear ring 23 within the limiting plate 22. Because the fixed support plate 31, the moving pressure plate 35 and the workpiece are clamped and fixed, the gear 24 rotates in the gear ring 23. The workpiece can be rotated along with the fixed support plate 31, the dynamic pressure plate 35, and the workpiece as a whole on the rotating shaft 32. It can rotate on its own axis while revolving around the revolution. Through the operation of the vacuum coating equipment 11, the workpiece can be coated. For workpieces with complex shapes, it avoids the formation of no film or thin film in the "recesses" of curved surfaces due to obstruction, and ensures uniform coverage of the entire surface. After the processing is completed, the rotation stops, and the electric push rod 27 retracts, moving the dynamic pressure plate 35 upward to reset. The workpiece is no longer clamped and fixed, and the coated workpiece can be removed, completing the coating process.

[0019] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description. Thus, it is intended that all variations falling within the meaning and scope of equivalents of the claims be included within this invention. No reference numerals in the claims should be construed as limiting the scope of the claims.
