Description

Technical Field

[0001] The utility model belongs to the field of electroplating clips, and particularly relates to an electroplating clip. Background Art

[0002] During the electroplating process of composite copper foils, in addition to using a feeding roller to drive the film forward for electroplating, a method of clamping the edge of the film by several electroplating clips and driving the film forward for electroplating at the same time is also adopted. However, the method of using electroplating clips is very likely to tear the film due to the pulling force between the electroplating clips, and at the same time, the film will be damaged due to the problem of the hard metal of the electroplating clips, seriously affecting the electroplating effect of the film and reducing the yield. Therefore, it is necessary to design an electroplating clip to solve the above problems. Content of the Utility Model

[0003] To solve the above technical problems, the utility model provides an electroplating clip to solve the problem that the existing electroplating clips in the market tear and damage the film when clamping the edge of the film and driving the film forward for electroplating as mentioned in the above background art.

[0004] To achieve the above purpose, the technical solution of the utility model is as follows:

[0005] An electroplating clip includes a fixed clip arm, on which a movable clip arm is vertically and movably connected. The bottom side of the fixed clip arm bends upward into a horizontal state. There is a first convex block on the fixed clip arm, and the first convex block is in a convex arc shape with a high middle and low sides. The bottom side of the movable clip arm bends upward into a horizontal state. There is a second convex block on the movable clip arm that is adapted to the first convex block, and the second convex block is in a concave arc shape with a high middle and low sides. A first silica gel sleeve is sleeved at the bottom end of the fixed clip arm, and a second silica gel sleeve is sleeved at the bottom end of the movable clip arm.

[0006] As a further improvement of the utility model, there are two groups of connecting blocks on the fixed clip arm. There is a placement groove on the connecting block, and a cover plate is provided on the placement groove. The movable clip arm is slidably connected up and down in the placement groove.

[0007] As a further improvement of the utility model, a limiting post is provided on the fixed clip arm at the placement groove, and there are two groups of through grooves on the movable clip arm. The limiting post moves up and down in the through grooves.

[0008] As a further improvement of the utility model, a downward through hole is opened on the upper connecting block, and a driving plate is provided below the through hole. The driving plate is fixed to the movable clip arm.

[0009] As a further improvement of the present utility model, a first storage groove matching the first bump is formed on the first silica gel sleeve. First platforms are arranged on both sides of the first storage groove. The middle part of the first storage groove is in a raised arc shape with the middle being high and both sides being low, and the middle part of the first storage groove is flush with the surface of the first bump.

[0010] As a further improvement of the present utility model, a second storage groove matching the second bump is formed on the second silica gel sleeve. Second platforms are arranged on both sides of the second storage groove. The middle part of the second storage groove is in a sunken arc shape with the middle being high and both sides being low, and the middle part of the second storage groove is flush with the surface of the second bump.

[0011] Compared with the prior art, the beneficial effects of the present utility model are as follows:

[0012] By arranging fixed clamping arms and movable clamping arms, and arranging first bumps and second bumps with arcs, the first bumps and the second bumps are more closely attached to the film. At the same time, a first silica gel sleeve and a second silica gel sleeve are arranged outside the first bumps and the second bumps to prevent the film from being mechanically scratched by the electroplating clip due to pulling, thereby tearing the film, and making the yield rate of the film higher during the electroplating process; Description of the Drawings

[0024] The present invention provides the following embodiments:

[0025] An electroplating clamp includes a fixed clamping arm 1. A movable clamping arm 2 is vertically and movably connected to the fixed clamping arm 1. The bottom side of the fixed clamping arm 1 is bent upward into a horizontal state. A first convex block 11 is provided on the fixed clamping arm 1. The first convex block 11 is in a convex arc shape with a higher middle and lower sides. The bottom side of the movable clamping arm 2 is bent upward into a horizontal state. A second convex block 21 adapted to the first convex block 11 is provided on the movable clamping arm 2. The second convex block 21 is in a concave arc shape with a higher middle and lower sides. A first silica gel sleeve 3 is sleeved on the bottom end of the fixed clamping arm 1, and a second silica gel sleeve 4 is sleeved on the bottom end of the movable clamping arm 2; when it is necessary to clamp a film, the first convex block 11 and the second convex block 21 are attached to clamp the film, so that the film is in an arc state when being clamped, and compared with clamping by flat clamping jaws, the arc method makes the clamped area of the film larger and the force more uniform, and it is less likely to break during the pulling process; at the same time, the first convex block 11 and the second convex block 21 are also made of conductive metal materials, and the film can be smoothly electroplated;

[0026] A first storage groove 31 matching the first convex block 11 is provided on the first silica gel sleeve 3. First platforms 32 are provided on both sides of the first storage groove 31. The middle part of the first storage groove 31 is in a convex arc shape with a higher middle and lower sides. The middle part of the first storage groove 31 is flush with the surface of the first convex block 11; a second storage groove 41 matching the second convex block 21 is provided on the second silica gel sleeve 4. Second platforms 42 are provided on both sides of the second storage groove 41. The middle part of the second storage groove 41 is in a concave arc shape with a higher middle and lower sides. The middle part of the second storage groove 41 is flush with the surface of the second convex block 21; the materials of the first silica gel sleeve 3 and the second silica gel sleeve 4 are softer than the metal materials, and can play a certain protective role for the film;

[0027] There are two sets of connecting blocks 12 provided on the fixed clamping arm 1. A placement groove 13 is provided on the connecting block 12, and a cover plate 14 is provided to cover the placement groove 13. An active clamping arm 2 is slidably connected up and down in the placement groove 13. A limiting post 15 is provided on the fixed clamping arm 1 at the position of the placement groove 13. Two sets of through grooves 22 are provided on the active clamping arm 2, and the limiting post 15 moves up and down in the through grooves 22. A downward through hole 16 is opened on the upper connecting block 12. A driving plate 23 is provided below the through hole 16, and the driving plate 23 is fixed to the active clamping arm 2. An external driving mechanism drives the driving plate 23 to move downward from the through hole 16, so that the active clamping arm 2 moves downward, making the first convex block 11 and the second convex block 21 fit together. At the same time, the movement of the limiting post 15 in the through groove 22 also plays a limiting role.
