Description

Technical Field

[0001] This utility model relates to the field of spot plating equipment technology, and in particular to a self-positioning spot plating fixture. Background Technology

[0002] Spot plating is an electroplating technique that forms a metallic coating in a specific area by applying an electric current locally. This technique is widely used in various industrial fields, such as electronics, automotive, and machinery manufacturing. Spot plating can improve the corrosion resistance, conductivity, and aesthetics of materials. For example, selective spot plating of gold on stainless steel connector terminals can meet high precision requirements, exhibiting good adhesion and corrosion resistance. Furthermore, spot plating technology is also used for electroplating gold onto large-area mobile phone SIM card solder pads to achieve precise plating and improve economic efficiency.

[0003] In spot plating operations, a conveyor belt is typically used to fix and transport the products to be plated. During operation, the belt presses the conveyor belt and the products on it onto the surface of the spot plating fixture. High-pressure spraying of the electroplating solution brings the solution into contact with the designated area of ​​the workpiece to form a localized plating layer. However, in actual operation, variations in the fixing position of the products on the belt can cause slight deviations in the positioning of the product and the electroplating solution spray nozzles on the fixture. This results in misalignment of the localized plating layer, ultimately affecting the final performance of the spot-plated product.

[0004] Therefore, in view of the shortcomings of the existing technology, it is necessary to design a self-positioning spot plating fixture to solve the above problems.

[0005] It should be noted that the above introduction to the technical background is only for the purpose of providing a clear and complete explanation of the technical solution of this utility model and facilitating the understanding of those skilled in the art. It should not be assumed that the above content is known to those skilled in the art simply because it has been described in the background section of this utility model. Utility Model Content

[0006] To overcome the shortcomings of the prior art, the present invention discloses a self-positioning spot plating fixture to solve the problem of inaccurate positioning of the electroplating solution nozzle caused by the positional deviation of the spot-plated product on the material strip during traditional spot plating operations.

[0007] This utility model discloses a self-positioning spot plating fixture, including an annular fixture body. The fixture body has several evenly distributed placement slots along its circumference. A floating positioning plate is detachably installed in each placement slot. The floating positioning plate has a limiting groove along its outer circumference. The inner side of the limiting groove is slidably connected to the edge of the placement slot. The distance between the bottom of the limiting groove and the opposite side of the placement slot is less than the width of the opposite side of the placement slot. A product positioning groove is provided at the upper end of the floating positioning plate. A guide ramp is provided at the upper end of the product positioning groove. An electroplating solution output hole communicating with the inner side of the fixture body is provided at the bottom of the product positioning groove. The spot plating product on the material strip is gradually entered into the product positioning groove through the cooperation of the guide ramp. During this process, the floating positioning plate slides along the placement slot to a certain extent to offset the positional deviation of the spot plating product, so that it can smoothly enter the product positioning groove and be aligned with the electroplating solution output hole.

[0008] Preferred technical solution: The main body of the fixture includes a positioning bottom ring, an annular mounting plate and a locking ring. The annular mounting plate is arranged on the side of the positioning bottom ring along its circumference. The side of the annular mounting plate away from the positioning bottom ring is provided with an opening groove along its circumference. The locking ring is detachably connected to the side of the annular mounting plate away from the positioning bottom ring. The locking ring and the opening groove together form a mounting slot hole, which is used to facilitate the disassembly and assembly of the floating positioning piece.

[0009] Preferred technical solution: The positioning bottom ring, the annular mounting plate and the locking ring surround the outer ring of the fixture body to form an annular material strip positioning groove, which is used to position the material strip and the belt pressing the material strip.

[0010] Preferred technical solution: The end of the electroplating solution outlet near the inner ring of the fixture body is a funnel-shaped hole with a gradually increasing diameter, which facilitates the delivery of the electroplating solution.

[0011] Preferred technical solution: The fixture body and the floating positioning plate are made of insulating material to prevent electroplating solution from depositing on them and forming a coating.

[0012] Preferred technical solution: A conductive coating is provided inside the electroplating solution outlet hole to improve the continuity of the electroplating solution's conductivity within the outlet hole, thereby improving the spot plating quality.

[0013] Due to the application of the above technical solution, the beneficial effects of this utility model compared with the prior art are as follows:

[0014] This utility model discloses a self-positioning spot plating fixture, which uses a floating positioning plate that floats along the outer periphery of the fixture body to position the spot plating products on the material strip. When the material strip passes through the fixture body, the product positioning groove on the floating positioning plate can automatically align with the spot plating products on the material strip, thereby improving the spot plating accuracy of the products. At the same time, the floating positioning plate and the fixture body are detachably connected, so when changing spot plating products, only the corresponding floating positioning plate needs to be replaced, saving operation time.

The upper end of the floating positioning plate 2 is provided with a product positioning groove 22. The upper end of the product positioning groove 22 is provided with a guide ramp 23. The bottom of the product positioning groove 22 is provided with an electroplating solution output hole 24 that connects to the inner side of the fixture body 1.

[0033] refer to Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 and Figure 6 As shown, the usage method and principle of this utility model are as follows: In use, when the external belt presses the material belt 3 against the spot plating fixture, the spot plating product 31 on the material belt 3 is pressed into the product positioning groove 22; during this process, the spot plating product 31 first contacts the guide ramp 23 and is guided into the product positioning groove 22 by the guide ramp 23; when there is a positional deviation between the spot plating product 31 and the product positioning groove 22, the spot plating product 31 will generate a lateral thrust on the guide ramp 23, thereby driving the floating positioning piece 2 to slide along the placement slot 14 to a certain extent, so that the spot plating product 31 is completely aligned with the product positioning groove 22, thereby ensuring that the electroplating solution output hole 24 is aligned with the spot plating product 31 and improving the spot plating accuracy.

[0034] like Figure 1 , Figure 2 and Figure 3 As shown, to facilitate the switching of spot plating product models, the fixture body 1 includes a positioning bottom ring 11, an annular mounting plate 12, and a locking ring 13.

The side of the annular mounting plate 12 away from the positioning bottom ring 11 has an opening groove along its circumference. The locking ring 13 is detachably connected to the side of the annular mounting plate 12 away from the positioning bottom ring 11. The locking ring 13 and the opening groove together form a mounting slot 14. When switching, it is only necessary to open the locking ring 13 to replace the floating positioning piece 2.

[0035] like Figure 1 , Figure 2 , Figure 3 and Figure 6 As shown, in order to improve positioning accuracy, the positioning bottom ring 11, the annular mounting plate 12 and the locking ring 13 surround the outer ring of the fixture body 1 to form an annular material strip positioning groove 1a, which is used to position the material strip 3.

[0036] like Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 5As shown, in order to improve the spot plating quality, the end of the electroplating solution outlet hole 24 near the inner ring of the fixture body 1 is a trumpet hole 24a with a gradually increasing diameter, which facilitates the electroplating solution to enter the electroplating solution outlet hole 24.

[0037] like Figure 1 , Figure 2 and Figure 3 As shown, to prevent the formation of a coating on the fixture, the fixture body 1 and the floating positioning plate 2 are made of insulating material.

[0038] like Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown, in order to improve the quality of spot plating, a conductive coating is provided inside the electroplating solution outlet hole 24 to prevent the electroplating solution from being interrupted in the electroplating solution outlet hole 24.
