Description

Technical Field

[0001] This invention relates to the field of electroplating technology, and more particularly to an electroplating apparatus. Background Technology

[0002] Electroplating is a process that uses the principle of electrolysis to plate a thin layer of other metals or alloys onto the surface of certain metals. It is a process that uses electrolysis to attach a metal film to the surface of metal or other material parts, thereby preventing metal corrosion and other oxidation reactions, and improving its wear resistance, conductivity, reflectivity, corrosion resistance and aesthetics.

[0003] Patent application CN202322337167.4 discloses an electroplating device, which includes an electroplating tank and columns installed at both ends of the tank. A vertically movable lifting bracket is installed between the two columns. Positioning plates and conductive plates are installed vertically within the lifting bracket. At least two hook bases are placed within the lifting bracket, and conductive rods that contact the conductive plates are installed within the hook bases. Electroplating hooks extending to the lower side of the lifting bracket are installed at the lower end of the hook bases. The upper ends of the electroplating hooks are fixedly connected to the conductive rods. A telescopic groove and a resistance plate installed within the telescopic groove are provided at the upper end of the hook base. The upper end of the resistance plate abuts against the positioning plate, and a telescopic spring is provided between the lower end of the resistance plate and the inner wall of the telescopic groove. The items to be electroplated are suspended on the hooks for electroplating. However, after electroplating, the products need to be removed from the hooks one by one, which is cumbersome and inconvenient. Furthermore, after removal, the products need to be repositioned before the next electroplating can be performed, resulting in low electroplating efficiency.

[0004] This invention was proposed in response to the shortcomings of existing technologies. Summary of the Invention

[0017] The embodiments of the present invention will now be described in detail with reference to the accompanying drawings:

[0018] Example 1:

[0019] like Figures 1 to 2As shown, this embodiment discloses an electroplating device, including a frame 1. An electroplating tank 27 is fixed on the frame 1. A support rod 2 and a screw 3 are arranged on the frame 1 above the electroplating tank 27. The screw 3 is driven to rotate by a motor 4. A slide plate 5 is also arranged above the electroplating tank 27. A threaded tube 10 is fixed on the slide plate 5 at a position corresponding to the screw 3. The screw 3 passes through the threaded tube 10 and is threadedly connected to the threaded tube 10. Support tubes 11 are fixed on the slide plate 5 at positions corresponding to the support rod 2. The support rod 2 passes through the support tube 11 and is slidably connected to the support tube 11. Feeding mechanisms 6 are symmetrically fixed on both sides of the slide plate 5 for feeding. Mechanism 6 includes feeding cylinders 7 symmetrically arranged on both sides of slide plate 5. The piston rod of feeding cylinder 7 is fixed with a fixing block 8. Feeding plate 12 is provided below feeding mechanism 6. Fixing pipe 13 is fixed on both sides of feeding plate 12 at positions corresponding to fixing block 8. Fixing hole 14 is provided on fixing pipe 13. Multiple hooks 15 are evenly fixed below feeding plate 12. Hydraulic cylinder 16 is fixed on frame 1 on both sides of electroplating tank 27. Fixing plate 17 is fixed at the piston rod of hydraulic cylinder 16. Fixing groove 18 is provided below fixing plate 17 for use with feeding plate 12. The product to be electroplated is suspended on the hook 15 on the feeding plate 12. Then, the feeding plate 12 is placed in the feeding mechanism 6. The feeding cylinder 7 is activated. After the solenoid valve connected to the feeding cylinder 7 is energized, compressed gas enters the feeding cylinder 7, and the piston rod on the feeding cylinder 7 extends. The two fixing blocks 8 are respectively inserted into the fixing holes 14 of the fixing tube 13. After the feeding plate 12 is fixed by the fixing blocks 8, the motor 4 drives the screw 3 to rotate. Since the screw 3 is threadedly connected to the threaded tube 10, when the screw 3 rotates, the threaded tube 10 moves in the direction of the screw 3, and the feeding plate 12 reaches above the electric slot. Both ends of the feeding plate 12 are inserted into the fixing slots 18 of the fixing plate 17. After the solenoid valve of the feeding cylinder 7 is de-energized, the piston rod of the feeding cylinder 7 moves. After the fixing blocks 8 separate from the fixing tube 13, the hydraulic cylinder 16 is activated, and the piston rod on the hydraulic cylinder 16 shortens. The two fixing plates 17 descend, and the feeding plate 12 descends with the fixing plates 17, thus feeding the product. The product suspended on plate 12 enters the electroplating solution in electroplating tank 27 for electroplating. During electroplating, a feeding plate 12 containing the product to be electroplated is fixedly suspended at another feeding mechanism 6. After the product in electroplating tank 27 is electroplated, hydraulic cylinder 16 is restarted, the piston rod on hydraulic cylinder 16 extends, and feeding plate 12 rises. After feeding plate 12 rises to the initial height, feeding cylinder 7 at the corresponding position is restarted, fixing block 8 enters the corresponding fixing tube 13 again, motor 4 drives screw 3 to rotate in the opposite direction, slide plate 5 returns to the initial position, and another product suspended above electroplating tank 27 is brought up for electroplating again. This cycle is repeated. This device can realize the electroplating operation of products, and after electroplating, the electroplated product can be transferred in one go without waiting to remove and place the product again, which can realize the electroplating of the product again, greatly improving the electroplating efficiency of the product.

[0020] The fixed block 8 is also provided with a limit block 9, and the fixed tube 13 is provided with a limit groove at the corresponding position of the limit block 9.

[0021] The fixed plate 17 is also fixed with a positioning ring 21. A push plate 22 is set above the positioning ring 21. A connecting block 24 is fixed at the bottom of the push plate 22. The bottom of the connecting block 24 has an arc-shaped structure. A connecting plate 23 is also fixed on the fixed plate 17 above the push plate 22. A connecting rod 25 is also fixed on the push plate 22. The connecting rod 25 passes through the connecting plate 23 and is slidably connected to the connecting plate 23. The connecting rod 25 is electrically connected to the negative terminal of the power supply. A spring 26 is also fixed between the push plate 22 and the connecting plate 23. When the metal feeding plate 12 moves, it contacts the connecting block 24 and pushes the connecting block 24 to rise, so that the product to be electroplated on the feeding plate 12 is electrically connected to the negative terminal of the power supply.

[0022] Example 2:

[0023] This embodiment discloses an electroplating device. Based on the structure and principle of Embodiment 1, this embodiment further includes a positioning cylinder 19 fixed on the fixing plate 17, with a positioning block 20 fixed to the end of the piston rod of the positioning cylinder 19. After the two ends of the feeding plate 12 of the electroplated product reach the fixing groove 18, the positioning cylinder 19 is activated, the piston rod of the positioning cylinder 19 extends, the positioning block 20 moves, and the positioning block 20 enters the fixing hole 14 of the fixing tube 13, thereby fixing the feeding plate 12. After electroplating is completed, the positioning cylinder 19 is activated, the piston rod of the positioning cylinder 19 shortens, and the positioning block 20 separates from the fixing tube 13.

[0024] The above are merely preferred embodiments of the present invention. It should be noted that, for those skilled in the art, various changes, modifications, substitutions and variations can be made to these embodiments without departing from the technical principles of the present invention.
