Description

Technical Field

[0001] This utility model relates to the field of vacuum plating equipment, and more particularly to the workpiece rotation mechanism of vertical vacuum plating equipment. Background Technology

[0002] The workpiece rotation mechanism of a vertical vacuum plating equipment is the core functional component used to drive the workpiece to be plating to move regularly within the vacuum plating chamber. Its main function is to drive the workpiece to rotate along a specific trajectory, so that the workpiece surface can uniformly contact the plating source (such as metal evaporation particles, ions, etc.), thereby ensuring that the plating layer on the workpiece surface has a consistent thickness and uniform color. It is one of the key mechanisms to improve the quality of vacuum plating products and is widely used in hardware, jewelry, electronic components and other fields that require surface plating treatment. When using the workpiece rotation mechanism of existing vertical vacuum plating equipment, the first step is to select a suitable workpiece mounting component, such as a fixing hook or bracket, according to the specifications of the workpiece to be plating, such as its size and weight. The workpieces are then fixed one by one onto the mounting component, ensuring they are securely mounted and do not contact each other. Next, the chamber door of the vacuum plating equipment is closed, and the vacuum system is activated to evacuate the plating chamber until the preset vacuum level is reached. Once the vacuum level meets the requirements, the drive motor of the rotation mechanism is started. The motor drives the rotating spindle via belt or gear transmission, and the spindle then drives the mounting component and workpiece to rotate circumferentially via a connecting rod or turntable. Simultaneously, the rotation speed of the rotation mechanism is set via the equipment control panel according to the plating process requirements, usually at a fixed speed or a fixed speed in stages. Throughout the plating process, the workpiece continues to rotate with the rotation mechanism until the plating process is complete. After plating is finished, the drive motor is turned off, and after the rotation mechanism has completely stopped, the vent valve of the vacuum chamber is opened. Once the pressure inside the chamber returns to normal, the chamber door is opened, and the plating workpiece is removed, completing one plating operation.

[0003] In practical applications, the existing workpiece rotation mechanism of the vertical vacuum plating equipment can only drive the workpiece to perform a single circular rotation during the plating process. The relative position changes between different areas of the workpiece surface and the plating source are relatively simple. For workpieces with complex shapes, such as those with grooves or holes, it is difficult for the complex parts to fully contact the plating source, which can easily lead to uneven plating or missed plating. Subsequent plating treatment is required, which increases the process cost and time cost. Therefore, the workpiece rotation mechanism of the vertical vacuum plating equipment was introduced to address the above problems. Utility Model Content

Detailed Implementation

[0019] 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.

[0020] Reference Figures 1-3 This utility model provides an embodiment of a workpiece rotation mechanism for a vertical vacuum plating equipment, comprising a vacuum plating device 1. The vacuum plating device 1 provides a sealed vacuum space for plating the workpiece. A motor 2 is fixedly connected to its top, and the motor 2 serves as a power source to drive a connecting plate 3 to rotate. The output end of the motor 2 is fixedly connected to the connecting plate 3. The connecting plate 3 can drive five sets of rotating mechanisms 4 and adjusting mechanisms 5 at the bottom to rotate synchronously. A rotating mechanism 4 is provided at the bottom of the connecting plate 3. The rotating mechanism 4 can drive the workpiece to rotate to ensure uniform plating. The rotating mechanism 4 includes a connecting column 411, which is the core component connecting the sliding rod A412 and the connecting plate 3. The top of the outer wall of the connecting column 411 is rotatably connected to the bottom of the connecting plate 3. The inner wall of the connecting column 411 is slidably connected to the sliding rod A412. The sliding rod A412 can slide along the inner wall of the connecting column 411 to adjust the height of the hook 413. A hook 413 is provided at the bottom for suspending the workpiece to be plated. A fixing bolt A415 is threadedly connected to the outer wall of the connecting column 411. After the fixing bolt A415 is tightened, the position of the slide rod A412 inside the connecting column 411 can be fixed. The extended end of the fixing bolt A415 abuts against the outer wall of the slide rod A412. A connecting vertical plate 414 is inserted into the outer wall of the slide rod A412. The connecting vertical plate 414 can be magnetically connected to assist in adjusting the relative position of the slide rod A412 and the hook 413. An adjustment mechanism 5 is provided on the outside of the connecting column 411. The adjustment mechanism 5 can change the meshing state of the double toothed disc 416 and the internal toothed ring 419. The number of teeth on the upper end of the outer wall of the double toothed disc 416 is more than the number of teeth on the lower end of the outer wall of the double toothed disc 416. The difference in the number of teeth on the upper and lower ends of the double toothed disc 416 can realize the adjustment of the rotation speed of the connecting column 411. The outer wall of the connecting vertical plate 414 is magnetically connected to the inner wall of the slide rod A412.

[0021] Reference Figures 1-3The connecting vertical plate 414 is rectangular. A groove is provided at the bottom of the slide rod A412, providing a track for the slider 417 to slide. The inner wall of the bottom of the slide rod A412 is slidably connected to the slider 417. The slider 417 can drive the hook 413 to move laterally to adapt to workpieces of different sizes. The bottom of the slider 417 is fixedly connected to the hook 413. There are six sets of sliders 417, symmetrically arranged at equal intervals at the bottom of the slide rod A412. Two sets of sliders 417 are symmetrically arranged on the bottom of the outer wall of each set of sliders 417. Vacuum plating equipment... A connecting rod 418 is fixedly connected to the inner wall of the device 1. The connecting rod 418 is used to fix the internal toothed ring 419 and keep its position stable. The extension end of the connecting rod 418 is fixedly connected to the internal toothed ring 419. The internal toothed ring 419 meshes with the double toothed disc 416, which can drive the connecting column 411 to rotate. The teeth on the outer wall of the double toothed disc 416 mesh with the teeth on the inner wall of the internal toothed ring 419. There are five sets of rotating mechanisms 4 and adjusting mechanisms 5. The five sets of rotating mechanisms 4 and adjusting mechanisms 5 are equidistantly arranged in a ring at the bottom of the connecting plate 3. The five sets of symmetrical arrangement can process more workpieces at the same time and improve the plating efficiency.

[0022] Reference Figures 1-3 The adjusting mechanism 5 includes a slide rod B511, which can drive the double-toothed sprocket 416 to move up and down along the connecting post 411. The double-toothed sprocket 416 is threadedly connected to the outer wall of the connecting post 411. The top of the slide rod B511 is fixedly connected to the bottom of the double-toothed sprocket 416. A sliding groove 513 is formed on the outer wall of the connecting post 411, which restricts the sliding direction of the slide rod B511. The slide bar B511 is connected to the inner wall of the slide groove 513. The outer wall of the slide bar B511 is threaded with a fixing bolt B512. After the fixing bolt B512 is tightened, the position of the slide bar B511 in the slide groove 513 can be fixed. The extended end of the fixing bolt B512 abuts against the inner wall of the slide groove 513. The slide groove 513 is located at the upper end of the connecting column 411. The location of the slide groove 513 at the upper end of the connecting column 411 can ensure that the double toothed disc 416 can accurately mesh with the internal toothed ring 419.

[0023] Working principle: In use, first adjust according to the size and quantity of the workpiece to be plated. Loosen the fixing bolt A415 and slide the slide rod A412 within the connecting column 411 to adjust the overall length so that the height of the hook 413 adapts to the workpiece. After adjustment, tighten the fixing bolt A415 to fix the position of the slide rod A412. At the same time, by sliding the slider 417 at the bottom of the slide rod A412, the positions of the hooks 413 are reasonably distributed by using six sets of equidistant and symmetrically arranged sliders 417 and two sets of hooks 413 symmetrically arranged at the bottom of each set of sliders 417 to adapt to workpieces of different sizes. Then, hang the workpiece on the hook 413. If it is necessary to adjust the lateral position of the hook 413, it can be adjusted by the magnetic connection between the connecting vertical plate 414 and the slide rod A412. Make fine adjustments to ensure stable workpiece mounting; then adjust the workpiece rotation speed as needed, loosen the fixing bolt B512, and slide the slide rod B511 in the groove 513 on the outer wall of the connecting column 411. Since the double toothed disc 416 is threadedly connected to the connecting column 411 and the top of the slide rod B511 is fixed to the double toothed disc 416, the sliding slide rod B511 can drive the double toothed disc 416 to move up and down, so that the upper tooth of the outer wall of the double toothed disc 416 has a large number of teeth or the lower tooth has a small number of teeth, which mesh with the inner toothed ring 419 fixed to the connecting rod 418 on the inner wall of the vacuum plating equipment 1. Because the number of teeth at the upper and lower ends is different, the rotation speed of the connecting column 411 can be changed after meshing. After the adjustment is completed, tighten the fixing bolt B512 to fix the position of the slide rod B511. Start motor 2, which drives the connecting plate 3 at the output end to rotate. When the connecting plate 3 rotates, it drives the five sets of equidistant rotating mechanisms 4 and adjusting mechanisms 5 at the bottom to rotate synchronously. While the connecting column 411 revolves with the connecting plate 3, the double toothed disc 416 on its outer wall meshes with the inner toothed ring 419, causing the connecting column 411 to rotate on its own axis. This, in turn, drives the workpiece on the slide rod A412 and the hook 413 to rotate on its own axis while revolving around the center of the circle, so as to achieve all-round and uniform coloring treatment of the workpiece in the vacuum coloring equipment 1. During the coloring process, the above adjustment steps can be repeated according to the actual situation to ensure the coloring effect.

[0024] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
