Description

Technical Field

[0001] This utility model relates to the field of electroplating workpiece hangers, and in particular to an electroplating workpiece hanger with an anti-slip clamping mechanism. Background Technology

[0002] Electroplating is a surface treatment process that uses the principle of electrolysis to deposit a metal or alloy layer on the surface of a conductor. Its purpose is to improve the appearance of materials, enhance corrosion resistance, improve wear resistance, electrical conductivity, or provide other functional requirements. Specifically, the workpiece to be treated is used as the cathode, and the plating metal is used as the anode. Both are placed simultaneously in an electrolyte containing plating metal ions, and a direct current is applied. The anode metal dissolves into ions, which are then reduced and deposited on the cathode surface, forming a uniform and dense metal plating layer.

[0003] In existing electroplating production processes, workpieces typically require specialized hangers to be fixed within the electrolytic tank to ensure uniform and stable deposition of metal ions on the workpiece surface. Currently, most commercially available electroplating workpiece hangers use hooks to suspend metal workpieces on the outside of the hanger, which cannot effectively clamp and fix the workpieces to be plated. The workpieces are prone to shaking or colliding with each other in the electroplating solution, increasing the risk of the hanger falling off and causing uneven distribution of the electroplating layer thickness, even resulting in scratches and voids. At the same time, metal parts of different sizes or shapes require the replacement or repeated adjustment of hangers, increasing production downtime and labor costs, which is particularly prominent in high-throughput automated electroplating production lines.

[0004] Therefore, there is an urgent need for a novel electroplating workpiece hanger structure that can achieve stable clamping, anti-slip and vibration resistance, and multi-size adaptive capability to improve electroplating quality and production efficiency. Based on this, we propose an electroplating workpiece hanger with an anti-slip clamping mechanism. Utility Model Content

[0005] The purpose of this section is to outline some aspects of embodiments of the present invention and to briefly describe some preferred embodiments. Simplifications or omissions may be made in this section, as well as in the abstract and title of the present invention, to avoid obscuring the purpose of these documents, and such simplifications or omissions should not be construed as limiting the scope of the present invention.

[0006] Therefore, the purpose of this utility model is to provide an electroplating workpiece hanger with an anti-slip clamping mechanism, which can solve the problems of existing hangers being unable to securely clamp electroplating workpieces, resulting in shaking and collision, uneven distribution of electroplating layer thickness and surface scratches and holes, and the need for frequent replacement or adjustment of hangers due to poor size and shape adaptability, which increases production downtime and labor costs.

[0007] To solve the above technical problems, this utility model provides an electroplating workpiece hanger with an anti-slip clamping mechanism, adopting the following technical solution: it includes a lifting plate, and an electroplating lifting assembly is provided at the bottom of the lifting plate. The electroplating lifting assembly includes a first arc-shaped side plate, a second arc-shaped side plate is connected to one side of the first arc-shaped side plate, a third arc-shaped side plate is installed on the side of the second arc-shaped side plate away from the first arc-shaped side plate, and a fourth arc-shaped side plate is also provided between the third arc-shaped side plate and the first arc-shaped side plate.

[0008] Positioning plates are installed on one side of the first, second, third, and fourth arc-shaped side plates. Positioning slots are also provided on the side of the first, second, third, and fourth arc-shaped side plates away from the positioning plates. Several sets of hanging windows are also opened on one side of the first, second, third, and fourth arc-shaped side plates.

[0009] Optionally, the positioning plate and the positioning slot are matched, and the positioning plate and the positioning slot are engaged by a snap-fit.

[0010] Optionally, telescopic adjustment grooves are provided on both sides of the inner wall of the hanging window, and positioning clamps are connected to both sides of the inner wall of the telescopic adjustment grooves. The positioning clamps are matched with the structure of the telescopic adjustment grooves. Two sets of grooves are provided on the inner side of the positioning clamps and the telescopic adjustment grooves, and a compression spring is connected between the two sets of grooves.

[0011] Optionally, the positioning clamp has a V-shaped groove at the center of the end away from the groove, a rectangular groove on the side of the positioning clamp near the V-shaped groove, and an arc groove on the side of the positioning clamp away from the rectangular groove.

[0012] Optionally, a lifting ring is installed on the top of the lifting plate, a hanging base plate is provided at the bottom of the lifting plate, and an annular groove is provided around the top of the hanging base plate.

[0013] Optionally, an embedded card plate is provided on the inner side of one end of the first, second, third, and fourth arc-shaped side plates. The embedded card plate matches the annular card groove structure, and the embedded card plate and the annular card groove are engaged in a snap-fit ​​relationship.

[0014] In summary, this utility model has at least one of the following beneficial effects:

[0015] 1. The electroplating workpiece hanger designed in this scheme uses the interlocking of an embedded card plate and an annular card slot, as well as the interlocking of a positioning card plate and a positioning card slot, to firmly connect and fix the four arc-shaped side plates together, forming a stable barrel-shaped structure. This structure can effectively prevent the arc-shaped side plates from swaying when immersed in the electroplating solution during the electroplating process, thereby avoiding mutual friction and collision, achieving stable support and protection for the electroplated workpiece, and improving the electroplating quality.

[0016] 2. The electroplating workpiece hanger designed in this scheme, by setting up a telescopic adjustment groove, positioning clamp, groove and compression spring at the hanging window, can adaptively adjust according to the shape and size of the metal part to be electroplated. The V-shaped groove, rectangular groove and arc groove opened at one end of the positioning clamp can stably clamp the corners of metal parts of different shapes. When the metal part is immersed in the electroplating solution, this structural design can prevent the metal part from swinging and causing mutual friction and collision, realize the stable hanging and electroplating of metal parts of different shapes, improve the versatility and processing stability of the equipment, reduce electroplating defects caused by metal part shaking, and improve production efficiency and product quality.

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.

[0025] Example: Refer to Figures 1 to 5 According to one embodiment of this utility model, an electroplating workpiece hanger with an anti-slip clamping mechanism includes a lifting plate 1. An electroplating lifting assembly 2 is provided at the bottom of the lifting plate 1. The electroplating lifting assembly 2 includes a first arc-shaped side plate 3. A second arc-shaped side plate 4 is connected to one side of the first arc-shaped side plate 3. A third arc-shaped side plate 5 is installed on the side of the second arc-shaped side plate 4 away from the first arc-shaped side plate 3. A fourth arc-shaped side plate 6 is also provided between the third arc-shaped side plate 5 and the first arc-shaped side plate 3. A positioning plate 7 is installed on one side of each of the first arc-shaped side plate 3, second arc-shaped side plate 4, third arc-shaped side plate 5, and fourth arc-shaped side plate 6. The side of the first arc-shaped side plate 3, second arc-shaped side plate 4, third arc-shaped side plate 5, and fourth arc-shaped side plate 6 away from the positioning plate 7... The device is also equipped with positioning slots 8. Several sets of hanging windows 9 are also provided on one side of the first arc-shaped side plate 3, the second arc-shaped side plate 4, the third arc-shaped side plate 5, and the fourth arc-shaped side plate 6. The electroplating workpiece hanger can clamp and fix the metal parts to be electroplated inside the hanging windows 9 through the cooperation of the telescopic adjustment groove 10, the positioning clamping plate 11, the groove 12, and the compression spring 13. This can prevent the metal parts from swinging and rubbing against each other when they are immersed in the electroplating solution. By using the V-shaped groove 14, the rectangular groove 15, and the arc groove 16 opened at one end of the positioning clamping plate 11, the corresponding positioning clamping groove can be selected according to the shape of the metal parts, which can improve the stability of the device for hanging and electroplating metal parts of different shapes.

[0026] The positioning plate 7 and the positioning slot 8 are structurally matched, and the positioning plate 7 and the positioning slot 8 are interlocked. Through the interlocking structure of the positioning plate 7 and the positioning slot 8, the first arc-shaped side plate 3, the second arc-shaped side plate 4, the third arc-shaped side plate 5, and the fourth arc-shaped side plate 6, which are suspended around the bottom of the lifting plate 1, can be spliced ​​and fixed together to form a barrel-shaped stable structure. This can prevent the first arc-shaped side plate 3, the second arc-shaped side plate 4, the third arc-shaped side plate 5, and the fourth arc-shaped side plate 6 from swinging and rubbing against each other when immersed in the electroplating solution. The inner walls of the hanging window 9 are open on both sides. The device is equipped with a telescopic adjustment groove 10, and positioning clamps 11 are connected to both sides of the inner wall of the telescopic adjustment groove 10. The positioning clamps 11 are structurally matched with the telescopic adjustment groove 10. Two sets of grooves 12 are respectively opened on the inner side of the positioning clamps 11 and the telescopic adjustment groove 10. A compression spring 13 is also connected between the two sets of grooves 12. Through the cooperation of the telescopic adjustment groove 10, positioning clamps 11, grooves 12 and compression springs 13, the hanging window 9 can clamp and fix the metal parts to be electroplated inside the hanging window 9, which can prevent the metal parts from swinging and rubbing against each other when immersed in the electroplating solution.

[0027] A V-shaped groove 14 is formed in the middle of the end of the positioning clamp 11 away from the groove 12. A rectangular groove 15 is formed on the side of the positioning clamp 11 near the V-shaped groove 14, and an arc groove 16 is formed on the side of the positioning clamp 11 away from the rectangular groove 15. By using the V-shaped groove 14, rectangular groove 15, and arc groove 16 formed at one end of the positioning clamp 11, the corresponding positioning clamping groove can be selected according to the shape of the metal part. For example, when the corners of the metal part are conical, the two sets of positioning clamps 11 with the V-shaped groove 14 can stably clamp the metal part with conical corners. When the corners of the metal part are rectangular, the two sets of positioning clamps 11 with the rectangular groove 15 can stably clamp the metal part with rectangular corners. When the corners of the metal part are arc-shaped, the two sets of positioning clamps 11 with the arc groove 16 can stably clamp the metal part with arc-shaped corners. To improve the stability of the equipment for electroplating metal parts of different shapes, a lifting ring 17 is installed on the top of the lifting plate 1, and a hanging base plate 18 is set at the bottom of the lifting plate 1. Annular slots 19 are also opened around the top of the hanging base plate 18. The annular slots 19 are used for the lifting connection between the electroplating lifting assembly 2 and the lifting plate 1. An embedded card plate 20 is also set on the inner side of one end of the first arc-shaped side plate 3, the second arc-shaped side plate 4, the third arc-shaped side plate 5, and the fourth arc-shaped side plate 6. The embedded card plate 20 matches the structure of the annular slot 19. The embedded card plate 20 and the annular slot 19 are engaged. Through the structural design of the engagement between the embedded card plate 20 and the annular slot 19, the first arc-shaped side plate 3, the second arc-shaped side plate 4, the third arc-shaped side plate 5, and the fourth arc-shaped side plate 6 can be suspended and connected to the bottom of the lifting plate 1.

[0028] Working Principle: The electroplating workpiece hanger designed in this scheme mainly consists of a lifting plate 1 and an electroplating lifting assembly 2. The electroplating lifting assembly 2 includes a first arc-shaped side plate 3, a second arc-shaped side plate 4, a third arc-shaped side plate 5, and a fourth arc-shaped side plate 6. The first arc-shaped side plate 3, the second arc-shaped side plate 4, the third arc-shaped side plate 5, and the fourth arc-shaped side plate 6 are connected by an embedded card plate 20 installed on the inner side of one end and an annular slot 19 opened around the top of the hanging base plate 18. Because the embedded card plate 20 and the annular slot 19 are structurally matched and have a snap-fit ​​fit, the first arc-shaped side plate 3, the second arc-shaped side plate 4, the third arc-shaped side plate 5, and the fourth arc-shaped side plate 6 can be suspended and connected. Around the bottom of the lifting plate 1, the first arc-shaped side plate 3, the second arc-shaped side plate 4, the third arc-shaped side plate 5, and the fourth arc-shaped side plate 6 are respectively equipped with positioning plates 7 and positioning slots 8 on both sides. Because the positioning plates 7 and positioning slots 8 are structurally matched and are interlocked, the first arc-shaped side plates 3, 4, 5, and 6 around the bottom of the lifting plate 1 can be spliced ​​and fixed together to form a barrel-shaped stable structure. This can prevent the first arc-shaped side plates 3, 4, 5, and 6 from swinging and rubbing against each other when immersed in the electroplating solution.

[0029] The electroplating workpiece hanger designed in this scheme uses hanging windows 9 respectively opened on one side of the first arc-shaped side plate 3, the second arc-shaped side plate 4, the third arc-shaped side plate 5, and the fourth arc-shaped side plate 6. These hanging windows 9, through the cooperation of the telescopic adjustment groove 10, the positioning clamping plate 11, the groove 12, and the compression spring 13, can clamp and fix the metal parts to be electroplated inside the hanging windows 9, preventing the metal parts from swinging and rubbing against each other when immersed in the electroplating solution. Furthermore, the V-shaped groove 14, the rectangular groove 15, and the arc groove 16 opened at one end of the positioning clamping plate 11 can also be used to adjust the position of the metal parts. The corresponding positioning clamping groove is selected according to the shape of the metal part. For example, when the corners of the metal part are conical, two sets of positioning clamping plates 11 with V-shaped slots 14 can stably clamp the metal part with conical corners. When the corners of the metal part are rectangular, two sets of positioning clamping plates 11 with rectangular slots 15 can stably clamp the metal part with rectangular corners. When the corners of the metal part are rounded, two sets of positioning clamping plates 11 with rounded slots 16 can stably clamp the metal part with rounded corners. This can improve the stability of the equipment for hanging electroplating of metal parts of different shapes.
