Abstract
Description
Technical Field
[0001] This utility model relates to the field of glass cover plate processing, and in particular to an electroplating device for glass cover plates. Background Technology
[0002] A glass cover is a transparent glass assembly used to cover or protect other components, commonly found in electronic devices (such as mobile phone screens, optical instruments, etc.) or industrial equipment. Glass covers undergo sealing electroplating in an electroplating chamber (processes such as vacuum evaporation and magnetron sputtering), primarily to achieve physical sealing and functional enhancement through the coating.
[0003] In existing glass cover electroplating processes, the common practice is to manually load multiple mounting plates onto the glass cover and then place them sequentially into the electroplating chamber. However, this traditional method is inefficient and lacks sealing. Because manual loading and unloading of mounting plates requires frequent opening and closing of the electroplating chamber door, the vacuum environment inside the chamber is repeatedly disrupted. The vacuum seals age faster due to mechanical fatigue, and the throughput per batch is relatively small, resulting in low overall efficiency.
[0004] Therefore, a special electroplating device for glass covers was designed to solve the above problems. Utility Model Content
[0005] In order to overcome the shortcomings of the existing technology, the present invention provides an electroplating device for glass cover plates.
[0006] The technical solution of this utility model is as follows: an electroplating device for glass covers, comprising a base and an electroplating chamber. The electroplating chamber is installed on the top of the base, and a door is hinged to the front of the electroplating chamber. A movable frame is movably placed inside the electroplating chamber. The movable frame consists of four circumferentially symmetrical frames. Each of the four frames is rotatably connected to a mounting plate. Several symmetrical placement slots are opened inside the mounting plates. Small gears are rotatably connected to the top of each of the four frames. A large gear is connected to the middle of the top of the movable frame. The large gear meshes with each of the external small gears. A support rod is provided on one side of the top of the movable frame, and the side of the support rod is fitted with... Equipped with a motor, the motor output shaft is connected to the central shaft of a large gear. Each slot on the mounting plate has a slidably connected clamping plate on both sides. The two clamping plates are in a relative state, and anti-slip grooves are provided on the opposite end faces of the two clamping plates. A sliding rod is provided at the sliding connection between the clamping plate and the slot on the mounting plate. A bushing is provided on the outside of the anti-slip groove corresponding to the sliding rod. A spring is provided between the bushing and the sliding rod. A locking rod is provided in the middle of the side of the door. A limit post is provided on the side of the electroplating chamber near the locking rod. A handle is rotated on the outside of the locking rod. A positioning groove is provided on the upper part of the handle, and the positioning groove is engaged in the limit post.
[0007] In one embodiment, the bottom of the mobile frame is symmetrically provided with four auxiliary wheels.
[0008] In one embodiment, an auxiliary ramp is provided at the bottom of the electroplating chamber at the position corresponding to the two auxiliary wheels at the front of the moving frame.
[0009] In one embodiment, the mounting plate further includes a sliding plate, a push rod, and a second spring. The sliding plate is slidably connected to the side of each limiting groove of the mounting plate, and the push rod is connected to the side of the sliding plate. A slotted groove is opened at the bottom of each limiting groove of the mounting plate. The lower part of the push rod is slidably engaged with the slotted groove. A limiting member is provided at one end of the lower part of the push rod, and the limiting member protrudes from the other side of the slotted groove. A second spring is provided between the lower part of the push rod and the mounting plate.
[0010] In one embodiment, an observation window is also included, which is embedded in the upper part of the hatch.
[0011] In one embodiment, a ramp plate is also included, with the top surface of the ramp plate flush with the bottom surface of the electroplating chamber.
[0012] The beneficial effects of this utility model are as follows: 1. This utility model integrates multiple mounting plates that rotate synchronously through the four circumferentially symmetrical frame structures of the movable frame, allowing multiple glass cover plates to be loaded at a time, greatly reducing the number of times the hatch is opened and closed. Combined with the meshing transmission of the large gear and the small gear, the surfaces of the glass cover plates are evenly exposed to the sputtering coating flow, eliminating edge accumulation and improving the uniformity of the coating, while ensuring the stability of the vacuum environment. The clamping plates automatically clamp the glass edges through the compression force of the slide rod and spring, and the anti-slip groove provides additional friction to ensure that the glass does not shift during high-speed rotation, avoiding coating displacement or peeling, and stabilizing the clamping force.
[0013] 2. This utility model uses a mechanical locking mechanism between a locking rod and a limiting post, combined with a lever-type handle, to ensure the vacuum seal between the door and the electroplating chamber. The auxiliary inclined block at the bottom of the electroplating chamber works in conjunction with the auxiliary wheels of the moving frame to improve the positioning accuracy of the moving frame and ensure the uniformity of the plating sputtering coverage.

Detailed Implementation
[0021] The present invention will be further described below with reference to the embodiments shown in the accompanying drawings.
[0022] Example: An electroplating apparatus for glass covers, such as Figures 1-6As shown, the device includes a base 1 and an electroplating chamber 2. The base 1 serves as the load-bearing foundation for the entire device, providing a rigid platform. The electroplating chamber 2 is mounted on top of the base 1, providing a vacuum-sealed environment for magnetron sputtering coating processes. A low-pressure environment is established by evacuating air using a vacuum pump, and a built-in magnetron sputtering target is used to deposit the coating material. A door 3 is hinged to the front of the electroplating chamber 2, used to open and close the chamber and ensure vacuum sealing. A movable frame 4 is placed inside the electroplating chamber 2. The movable frame 4 consists of four circumferentially symmetrical frames. Four auxiliary wheels are symmetrically arranged at the bottom of the moving frame 4. Auxiliary inclined blocks are provided at the bottom of the electroplating chamber 2 corresponding to the positions of the two auxiliary wheels at the front of the moving frame 4. Mounting plates 5 are rotatably connected to each of the four frames of the moving frame 4. Several symmetrical placement slots are opened inside the mounting plates 5. Small gears 6 are connected to the top of each of the four frames via bearings. A large gear 7 is connected to the center of the top of the moving frame 4 via a bearing. The large gear 7 meshes rotatably with each of the external small gears 6. A support rod is provided on one side of the top of the moving frame 4, and a motor is bolted to the side of the support rod. 8. The output shaft of motor 8 is connected to the central shaft of large gear 7 via a coupling. Large gear 7 meshes with small gear 6, thereby transmitting power from motor 8 and driving mounting plate 5 to rotate. Clamping plates 9 are slidably connected to both sides of each placement slot in mounting plate 5. The two clamping plates 9 are in a relative position, and anti-slip grooves are provided on the opposite end faces of the two clamping plates 9. A sliding rod 10 is provided at the sliding connection between the clamping plate 9 and the placement slot of mounting plate 5. The clamping plate 9 and the sliding rod 10 adaptively clamp glass covers of different thicknesses, and the anti-slip grooves correspond to the sliding rod 10. An external bushing 101 is provided, and a spring 11 is provided between the bushing 101 and the slide rod 10. The spring 11 compresses the slide rod 10 through the bushing 101. A locking rod 15 is welded to the middle of the side of the door 3. A limit post 16 is provided on the side of the electroplating tank 2 near the locking rod 15 by bolts. A handle 17 is rotatably sleeved on the outside of the locking rod 15. A positioning groove is opened on the upper part of the handle 17. The positioning groove is inserted into the limit post 16. When the handle 17 is pressed down, a locking force is applied through the lever principle, and the locking rod 15 is inserted into the positioning groove of the limit post 16.
[0023] like Figure 5 and Figure 6 As shown, it also includes a sliding plate 12, a top rod 13, and a second spring 14. The sliding plate 12 is slidably connected to the side of each limiting groove of the mounting plate 5. The top rod 13 is welded to the side of the sliding plate 12. A slotted groove is opened at the bottom of each limiting groove of the mounting plate 5. The lower part of the top rod 13 slides in cooperation with the slotted groove. A limiting member is provided at one end of the lower part of the top rod 13, which protrudes on the other side of the slotted groove. A second spring 14 is provided between the lower part of the top rod 13 and the mounting plate 5. Pushing the top rod 13 to move along the slotted groove drives the sliding plate 12 to move synchronously to adjust the lateral positioning of the glass cover, which is compatible with dimensional tolerances. The second spring 14 provides adaptive pressure to ensure that the center of the glass cover is aligned.
[0024] like Figure 1As shown, it also includes an observation window 18. An observation window 18 is embedded in the upper part of the hatch 3 for real-time monitoring of the coating deposition status. The observation window 18 is made of explosion-proof glass and can be used with an external CCD camera to detect the coating thickness.
[0025] like Figure 1 As shown, it also includes a ramp plate 19. The ramp plate 19 is provided on the front side of the base 1. The top surface of the ramp plate 19 is flush with the bottom surface of the electroplating tank 2. The auxiliary wheels of the guide frame 4 slide smoothly. The ramp plate 19 assists in the loading and unloading of the guide frame 4 and reduces frictional resistance.
[0026] Before electroplating, the operator opens the door 3, pulls the handle 17 to release the locking rod 15 and the limit post 16, the spring 11 returns to its original position, and the door 3 rotates around the hinge to the fully open position. Then, the moving frame 4 is pushed into the electroplating chamber 2 through the ramp plate 19 on the front side of the base 1. The top surface of the ramp plate 19 is flush with the bottom surface of the electroplating chamber 2 to ensure that the auxiliary wheels at the bottom of the moving frame 4 slide smoothly. The motor 8 starts self-checking, and the large gear 7 drives the four small gears 6 to rotate freely to verify the gear meshing status. Compressed air is used to blow the inner wall of the electroplating chamber 2 to remove residual plating particles. The process is then observed through the observation window 18. Check the integrity of the vacuum seal ring inside the chamber to ensure subsequent vacuum sealing. Then, place the glass cover plate to be coated into the mounting plate 5 placement slot of the moving frame 4. The clamping plates 9 on both sides slide on the slide rod 10, and the compression force of the spring 11 automatically clamps the glass edge. The anti-slip groove of the clamping plate 9 increases friction to prevent the glass from sliding. If the glass size difference is large, the sliding plate 12 can be manually adjusted. If there is a certain difference in glass size, manually push the sliding plate 12 to move along the straight slide groove. The top rod 13 drives the limiting component to hold the side of the glass. The second spring 14 provides adaptive pressure to ensure the glass... The glass center is aligned with the axis of mounting plate 5 to ensure that glass of different specifications is centered. The chamber door 3 is closed, the locking rod 15 is inserted into the positioning groove of the limiting post 16, and the handle 17 is pressed down to the horizontal position. A locking force is applied through the lever principle to ensure that the chamber door 3 seals the bottom of the electroplating chamber 2. The auxiliary inclined block is in contact with the front auxiliary wheel of the moving frame 4. The auxiliary wheel rolls along the inclined block, so that the moving frame 4 is accurately locked into the center position of the electroplating chamber 2. The electroplating chamber 2 is started, and the pressure inside the chamber drops to the target vacuum level. The magnetron sputtering target inside the electroplating chamber 2 is energized, and plasma is generated on the surface of the target. The plating atoms are sputtered at high speed onto the glass surface. Motor 8 drives large gear 7, which meshes with four small gears 6, causing mounting plate 5 to rotate around its own axis. Then, the growth status of the coating is monitored through observation window 18. After the coating is deposited, the power supply to the target material in electroplating chamber 2 is turned off to maintain a vacuum environment so that the coating atoms can migrate fully to form a dense structure. After the external gas source fills the electroplating chamber 2 with high-purity nitrogen to restore normal pressure and prevent coating oxidation, the chamber door 3 is opened, the locking lever 15 is released, and spring 11 pushes the clamping plate 9 to reset. The operator pulls out the moving frame 4 along the ramp 19, and the auxiliary wheels roll to ensure that the moving frame 4 moves out smoothly.
