[0002] The substrate of PCB is a hard or soft thin board. As electronic communication products develop towards thinness, there is an increasing demand for plasma, copper deposition and electroplating operations on thin boards. However, for PCB manufacturers, especially those without production lines and equipment specifically for thin boards, the problem of thin boards getting stuck and stacked during production is difficult to overcome. The current practice in the industry is to use copper wires and thicker dummy boards to drag the thin boards for operation, but this method of operation is inefficient and difficult to operate.

[0023] In order to further explain the technical means and effects adopted by the present invention to achieve the predetermined purpose of the utility model, the specific implementation method, structure, characteristics and effects of the present invention are described in detail below in combination with the accompanying drawings and preferred embodiments.

[0024] Example: Please refer to Figure 1-4 A clamp for electroplating includes a support frame 1 and a clamping assembly. The support frame 1 is in a U-shaped shape. The clamping assembly is arranged at two opposite inner sides of the support frame 1, such as the front and rear inner sides. The clamping assembly includes a clamping plate 2 and a clamping member 21. A plurality of clamping members 21 are fixedly connected to the clamping plate 2. A clamping groove is arranged in the middle of the clamping member 21. The clamping groove is used to facilitate positioning of the clamped thin plate at the clamping groove. Figure 4 As shown, the upper and lower sides of the clamping groove are provided with inclined surfaces connected to the clamping groove, and the inclined surfaces make it easy to load and unload the thin plate and facilitate the edge of the thin plate to contact the electroplating solution. The clamping plate 2 is connected to the supporting frame 1 through a spring 12, and a plurality of springs 12 are provided to strengthen the connection between the clamping plate 2 and the supporting frame 1. In this embodiment, three springs 12 are connected to one clamping plate 2. Further, a limit member 13 is fixedly connected to the supporting frame 1, and a matching block 23 is provided at the lower end of the clamping plate 2. A matching groove that matches the limit member 13 is provided on the matching block 23, and the limit member 13 allows the clamping plate 2 to move only along the length direction of the limit member 13. Further, the limit member 13 is a square block, which prevents the clamping plate 2 from rotating on the limit member 13. There are a plurality of limit blocks and matching blocks 23 respectively, which strengthen the directional movement of the clamping plate 2. In this embodiment, two matching blocks 23 are provided at the lower end of one clamping plate 2, and two corresponding limit blocks on the inner side of the supporting frame 1 corresponding to the clamping plate 2 are also provided. Furthermore, a hook assembly is provided on the splint 2, and the hook assembly is preferably arranged at the midline position of the splint 2 in the up and down directions. A fixing column 111 cooperating with the hook assembly is provided on the supporting frame 1, and the hook assembly includes a hook 22, a limiting ring 221 and a positioning ring 222. The hook 22 includes a hook-shaped head, a rod-shaped middle part and a ring-shaped tail. The tail of the hook 22 is sleeved on the limiting ring 221, and the head of the hook 22 can be hung on the positioning ring 222. When the hook assembly is in use, the head of the hook 22 is hooked on the fixing column 111. When the hook assembly is not in use, the head of the hook 22 is hung on the positioning ring 222. A groove 11 is provided on the supporting frame 1, and the fixing column 111 is fixedly connected to the bottom of the groove 11, so that the entire clamp has no part protruding from the surface of the supporting frame 1, which is convenient for the roller press to be able to closely adhere to the surface of the supporting plate for rolling and conveying.

[0025] Working principle of this embodiment: This embodiment provides a clamp for electroplating, which can clamp a thin plate between two opposite inner sides of a supporting frame 1 through a clamping assembly. When not clamped, the spring 12 stretches naturally. When clamping is required, first one side of the thin plate is abutted against a clamp 21 on a clamp 2, and the spring 12 connected to the clamp 2 is compressed. Then the spring 12 connected to another clamp 2 is compressed to abut the other side of the thin plate against the clamp 21 on the clamp 2, so that both sides of the thin plate are clamped by the corresponding clamps 21 respectively. The stretching force of the springs 12 on both sides makes the thin plate clamped, which is convenient for clamping the thin plate workpiece for plasma, copper deposition, electroplating and other operations, improving the production efficiency of the thin plate and reducing the production difficulty of the thin plate. Further, the hook assembly allows the hook 22 to hook the fixed column 111 when the spring 12 connected to the clamp 2 is compressed, so that the position of the clamp 2 is fixed, and there is enough time to place one side of the thin plate against the clamp 21. When the spring 12 needs to be stretched, the hook 22 can be moved away from the fixed column 111. Furthermore, the limiting member 13 and the matching block 23 allow the clamping plate 2 to move only along the length direction of the limiting member 13 , thereby preventing the clamping plate 2 from shaking or deflecting.
