Description

Technical Field

[0001] The utility model relates to the technical field of electroplating equipment, in particular to an external support clamp for electroplating. Background Art

[0002] Electroplating can be divided into UV vacuum electroplating and water electroplating according to the process. During electroplating, in order to ensure that the workpiece has good electroplating quality, a clamp is needed to fix the workpiece. The existing clamp clamps the workpiece inwardly, such as the Chinese utility model patent with publication number CN213507268U and patent name "An easy-to-use electroplating clamp for electronic components". The existing clamp clamps the workpiece with a larger clamping surface to fix it, which can ensure a stable connection between the clamp and the workpiece and avoid the workpiece being unable to be electroplated normally due to poor contact with the clamp; but the clamp with such a fixing method covers a large area of ​​the workpiece surface. When used in the electroplating processing scene of small workpieces, it will cause uneven plating of small workpieces or areas that cannot be plated, resulting in poor electroplating effect of small workpieces.

DETAILED DESCRIPTION

[0020] In order to have a clearer understanding of the technical features, purposes and effects of the present utility model, the specific implementation methods of the present utility model are now described in detail with reference to the accompanying drawings.

[0021] like Figures 1 to 3An external support clamp for electroplating according to an embodiment includes a base 1 and an external support elastic member 2; the external support elastic member 2 is located above the base 1, and the external support elastic member 2 includes an integrally formed connecting spring piece 21 and two external support spring pieces 22; the two external support spring pieces 22 are arranged on the left and right, and one end of each of the two external support spring pieces 22 is connected by the connecting spring piece 21, and the two external support spring pieces 22 are gradually arranged away from each other in a direction away from the connecting spring piece 21, and a clamping head 23 is formed at the other end of each of the two external support spring pieces 22, and the two external support spring pieces 22 have an elastic tendency to move away from each other, so that the two clamping heads 23 can cooperate to externally support and fix the workpiece 4.

[0022] The working principle of this embodiment:

[0023] This clamp is used in conjunction with a workpiece 4 having a specific structure (the workpiece 4 in this embodiment is a pendant), and the workpiece 4 is formed with two relatively arranged hanging ring structures 41. When in use, by applying a force to the two outer supporting spring pieces 22 of the outer supporting elastic member 2, the two clamping heads 23 are brought close to each other, at this time, the two hanging ring structures 41 of the workpiece 4 are placed on both sides of the outer supporting elastic member 2, and the two hanging ring structures 41 are placed on the two clamping heads 23 of the outer supporting elastic member 2 in a one-to-one correspondence, at this time, the application of force to the two outer supporting spring pieces 22 of the outer supporting elastic member 2 is stopped, and under the action of elasticity, the two clamping heads 23 of the outer supporting elastic member 2 cooperate to fix the workpiece externally. The design of connecting the clamp with the hanging ring structure 41 of the workpiece 4 through the clamping head 23 makes the area of ​​the workpiece 4 surface covered by the clamp smaller, which is suitable for the electroplating processing scenario of small workpieces. The design of clamping the workpiece 4 by external support fixation makes the connection structure between the clamp and the workpiece 4 stable, and there will be no poor contact with the workpiece 4 that makes the workpiece 4 unable to be electroplated normally.

[0024] like Figures 1 to 3 As shown, the connecting spring piece 21 includes a horizontal plate portion 211 and two vertical plate portions 212, one side of the horizontal plate portion 211 is connected and fixed to the base 1, one end of the horizontal plate portion 211 is connected to one end of one of the vertical plate portions 212, and the other end of the horizontal plate portion 211 is connected to one end of the other vertical plate portion 212, so that the horizontal plate portion 211 and the two vertical plate portions 212 are connected to form a notch structure; the other end of each of the two vertical plate portions 212 is connected to the two external support spring pieces 22 one by one. The connecting spring piece 21 with the notch structure has better elastic performance and can withstand more bending without permanent deformation, thereby improving durability.

[0025] like Figures 1 to 3As shown, the connecting spring piece 21 also includes two inner folding plate portions 213, one inner folding plate portion 213 corresponds to a vertical plate portion 212 and an outer supporting spring piece 22, one end of the inner folding plate portion 213 is connected to the vertical plate portion 212, and the other end of the inner folding plate portion 213 is connected to the outer supporting spring piece 22, and the two inner folding plate portions 213 are gradually arranged close to each other in the direction away from the connecting spring piece 21. When the outer supporting spring piece 22 is compressed, such a design can reduce the degree of compression deformation of the vertical plate portion 212 of the connecting spring piece 21, and further improve the elasticity of the outer supporting elastic member 2.

[0026] like Figure 1 and Figure 3 As shown, each outer support spring piece 22 includes a connecting plate portion 221 and a narrowing portion 222; one end of the connecting plate portion 221 is connected to the connecting spring piece 21, and the other end of the connecting plate portion 221 is connected to one end of the narrowing portion 222. The narrowing portion 222 gradually narrows in the direction away from the connecting plate portion 221, and the other end of the narrowing portion 222 forms the clamping head 23. The clamping head 23 is a long strip structure, one end of the two clamping heads 23 is respectively connected to the corresponding outer support spring piece 22, and the other ends of the two clamping heads 23 are arranged away from each other, and the angle formed between the two clamping heads 23 is greater than the angle formed between the two outer support spring pieces 22. Such a structure makes the connection and installation between the clamping head 23 and the hanging ring structure 41 of the workpiece 4 more convenient, and the design that the angle formed between the two clamping heads 23 is greater than the angle formed between the two external supporting spring sheets 22 can form a hook head structure between the clamping head 23 and the external supporting spring sheets 22, which can effectively prevent the hanging ring structure 41 of the workpiece 4 from detaching from the clamping head 23 by itself.

[0027] like Figures 1 to 3As shown, the base 1 includes an inserting portion 11 and a flange portion 12; the cross-sectional profile of the inserting portion 11 is rectangular, and one end of the inserting portion 11 is connected to one side of the flange portion 12; the diameter of the flange portion 12 is greater than the maximum spacing of the cross-sectional profile of the inserting portion 11; the outer support elastic member 2 is connected to the side of the flange portion 12 facing away from the inserting portion 11. In this embodiment, the clamp is used in conjunction with an external support seat 5, which is located below the base 1 of the clamp, and a rectangular cross-sectional embedding hole 51 is formed on the top surface of the external support seat 5; the inserting portion 11 is embedded in the embedding hole 51, and since the cross-sectional profiles of the inserting portion 11 and the embedding hole 51 are both rectangular structures, the base 1 and the external support seat 5 are positioned in the circumferential direction; at the same time, the flange portion 12 abuts against the top surface of the external support seat 5, so that the base 1 and the external support seat 5 are positioned in the axial direction. Through such a design, the connection structure between the base 1 and the external support seat 5 of the clamp is stable and convenient to position, and the clamp can be easily disassembled and installed with the external support seat 5. In addition, the external support seat 5 can be fixed on the electroplating equipment to facilitate the installation and disassembly of the clamp and the electroplating equipment; the external support seat 5 can also be installed and connected on the transmission mechanism, so that the workpiece 4 can be transported by clamping on the clamp, so as to be suitable for mass automated production.

[0028] like Figures 1 to 3 As shown, the base 1 also includes a boss portion 13, the cross section of the boss portion 13 is a rectangular structure, one end of the boss portion 13 is connected to the side of the flange portion 12 facing away from the insertion portion 11, and the external support elastic member 2 is connected to the other end face of the boss portion 13.

[0029] like Figure 1 and Figure 2 As shown, a through hole connecting the two side surfaces of the horizontal plate portion 211 is formed in the middle thereof; a connecting nut 3 is also included, and a connecting stud 14 is formed on the end surface of the boss portion 13 of the base 1. One end of the connecting stud 14 passes through the through hole of the horizontal plate portion 211 and is threadedly connected to the connecting nut 3, so that the horizontal plate portion 211 is clamped between the connecting nut 3 and the bottom surface of the base 1. Such a design can facilitate the installation and removal of the external support elastic member 2, and is convenient for replacing the external support elastic member 2 during daily maintenance.
