Description

Technical Field

[0001] This utility model relates to the field of electroplating fixture technology, and in particular to a spot plating material limiting fixture. Background Technology

[0002] In electroplating, spot plating is a technique for electroplating specific areas of a product, widely used in the production of precision components such as electronic components and connectors. Traditional spot plating fixtures suffer from problems such as uneven plating solution distribution, inaccurate strip positioning, and easy plating solution overflow when performing lateral plating on products, leading to unstable plating quality and low efficiency. Furthermore, existing fixtures are difficult to adapt to the processing requirements of strips of different sizes, lacking sufficient adjustment flexibility.

[0003] Therefore, in view of the shortcomings of the existing technology, it is necessary to design a spot plating strip limiting fixture to solve the above problems.

[0004] 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

[0005] To overcome the shortcomings of the prior art, the present invention discloses a spot plating material limiting fixture, which solves the problems of uneven distribution of electroplating solution, inaccurate positioning and overflow. It has the advantages of simple structure and strong adaptability, and is suitable for spot plating of precision parts.

[0006] This utility model discloses a spot plating material with a limiting fixture, comprising:

[0007] The ring-shaped fixture body has an annular spot plating tank on its outer periphery. At least two electroplating solution conveying holes are evenly distributed along the circumference at the bottom of the annular spot plating tank. The electroplating solution conveying holes penetrate to the inner side of the ring-shaped fixture body, and the electroplating solution is conveyed from the inside of the ring-shaped fixture body to the outside through the electroplating solution conveying holes. At least two adjusting grooves are provided at intervals along the circumference on one side of the annular spot plating tank. The length direction of the adjusting grooves is set along the axial direction of the ring-shaped fixture body.

[0008] An annular baffle covers the annular spot plating tank. Its side near the adjustment tank is sealed to the main body of the annular fixture, and its other side forms a gap with the side of the annular spot plating tank for the electroplating product to extend into, which is used to guide the electroplating solution to electroplat the side of the electroplating product.

[0009] An annular limiting baffle is adjustablely installed on the outer periphery of the annular fixture body by means of bolts and adjustment grooves. The side of the annular limiting baffle near the annular spot plating groove forms an annular limiting groove for the material strip with the annular spot plating groove.

[0010] Preferred technical solution: The two sides of the outer periphery of the ring fixture body are provided with ring-shaped anti-splash baffles to prevent the plating solution from overflowing, thereby preventing the plating solution from splashing.

[0011] Preferred technical solution: An annular positioning groove is provided along the circumferential direction inside the annular limiting groove of the material strip. The annular positioning groove is located on one side of the connection between the annular baffle and the main body of the annular fixture, and is used to guide the material strip to be accurately positioned.

[0012] Preferred technical solution: The annular limiting baffle is made of elastic material to accommodate strips of different thicknesses.

[0013] Preferred technical solution: The electroplating solution delivery holes are evenly distributed along the circumference of the annular spot plating tank to ensure uniform supply of electroplating solution.

[0014] Preferred technical solution: The connection between the annular cover plate and the main body of the annular fixture is welding or integral molding.

[0015] Preferred technical solution: The distance between the bottom of the annular spot plating tank and the annular baffle is 1.2-1.5 times the length of the electroplating surface of the electroplating product, so as to optimize the coverage effect of the electroplating solution.

[0016] Due to the application of the above technical solution, the beneficial effects of this utility model compared with the prior art are as follows:

[0017] 1) Uniform distribution of electroplating solution: The bottom of the annular spot plating tank is equipped with multiple circumferentially evenly distributed electroplating solution conveying holes to ensure that the electroplating solution is evenly conveyed from the inside to the outside, avoiding insufficient or accumulated electroplating solution in some areas, and improving the electroplating quality.

[0018] 2) Precise positioning of the strip: The strip is precisely positioned by the annular limiting baffle and the annular spot plating tank forming an annular limiting groove, combined with the annular positioning groove design, which prevents the strip from shifting during the electroplating process and ensures the consistency of the electroplating area.

[0019] 3) High adaptability: The annular limit baffle is made of elastic material and can be adjusted by adjusting the groove and bolts to adapt to strips of different thicknesses and sizes, thus improving the versatility of the fixture.

[0020] 4) The design of the adjustment groove and bolts allows the position of the annular limit baffle to be flexibly adjusted, making it easy to quickly adapt to different production needs and improve production efficiency. Attached Figure Description

[0032] Example:

[0033] like Figure 1 As shown, this utility model discloses a spot plating material limiting fixture, including an annular fixture body 1, an annular cover plate 2, and an annular limiting baffle plate 3. The main components of the above-mentioned utility model will be described in detail below:

[0034] like Figure 1 , Figure 2 and Figure 3 As shown, an annular spot plating tank 11 is provided on the outer periphery of the annular fixture body 1. Multiple electroplating solution conveying holes 12 are evenly distributed circumferentially at the bottom of the annular spot plating tank 11. The electroplating solution conveying holes 12 penetrate to the inner side of the annular fixture body 1, and the electroplating solution in the annular fixture body 1 is conveyed to the outside through the electroplating solution conveying holes 12. The even arrangement ensures the stability of the electroplating solution flow during the conveying process. Multiple adjusting grooves 13 are provided circumferentially at intervals on one side of the annular spot plating tank 11. The length direction of the adjusting grooves 13 is arranged along the axial direction of the annular fixture body 1.

[0035] like Figure 1 , Figure 2 and Figure 3As shown, the annular shield 2 covers the annular spot plating tank 11. The side of the shield 2 near the adjustment tank 13 is sealed to the annular fixture body 1, and the other side forms a gap with the side of the annular spot plating tank 11 for the electroplating product 6 to extend into. The annular shield 2 and the annular spot plating tank 11 cooperate to change the flow direction of the electroplating solution in the annular spot plating tank 11, so that the electroplating solution flows from the side to the electroplating product 6, and the part of the electroplating product 6 extending into the gap is electroplated.

[0036] like Figure 1 , Figure 2 and Figure 3 As shown, the annular limiting baffle 3 is adjustablely installed on the outer periphery of the annular fixture body 1 by means of bolts 4 and adjusting groove 13. The side of the annular limiting baffle 3 near the annular spot plating groove 11 forms an annular limiting groove for the material strip with the annular spot plating groove 11. By adjusting the position of the annular limiting baffle 3, the non-ventilated material strip 5 is laterally limited to prevent horizontal deviation.

[0037] The method of use and principle of this utility model are as follows:

[0038] Step 1: Place the material strip 5 on the outer periphery of the ring fixture body 1, so that the end of the electroplating product 6 to be electroplated extends into the gap formed by the ring shield 2 and the side of the ring spot plating tank 11.

[0039] Step 2: Loosen bolt 4, slide the annular limit baffle 3 until it fits against the side of the material strip 5, and tighten bolt 4 to fix it; it has strong compatibility with material strips 5 of different sizes.

[0040] Step 3: Start the electroplating solution delivery system. The electroplating solution is evenly injected into the annular spot plating tank 11 through the electroplating solution delivery hole 12. Under the guidance of the annular baffle 2, the flow direction of the electroplating solution is changed, so that the electroplating solution covers the electroplating surface of the electroplating product 6 along the axial direction of the annular fixture body 1, completing the local electroplating.

[0041] like Figure 1 , Figure 2 and Figure 3 As shown, the outer sides of the ring fixture body 1 are provided with ring-shaped anti-splash baffles 14 to prevent the plating solution from overflowing, which are used to prevent the plating solution from splashing.

[0042] like Figure 1 , Figure 2 and Figure 3 As shown, an annular positioning groove 15 is provided along the circumferential direction inside the annular limiting groove of the material strip. The annular positioning groove 15 is located on one side of the connection between the annular cover plate 2 and the annular fixture body 1, and is used to cooperate with the protruding structure on the material strip 5 for precise positioning.

[0043] like Figure 1 , Figure 2 and Figure 3As shown, the annular limiting baffle 3 is made of elastic material, such as rubber, plastic and elastic plastic, to prevent jamming when it is in contact with the material strip 5, so as to accommodate material strips 5 of different thicknesses.

[0044] like Figure 1 , Figure 2 and Figure 3 As shown, the connection between the annular cover plate 2 and the annular fixture body 1 is either welding or integral molding.

[0045] like Figure 1 , Figure 2 and Figure 3 As shown, the distance between the bottom of the annular spot plating tank 11 and the annular shield 2 is 1.2-1.5 times the length of the electroplating surface of the electroplated product 6, so that the electroplating end of the electroplated product 6 can be completely inserted into the gap formed by the annular shield 2 and the side of the annular spot plating tank 11, thereby optimizing the coverage effect of the electroplating solution.

[0046] This invention solves the problems of uneven electroplating solution distribution, inaccurate material strip positioning, and poor compatibility of traditional spot plating fixtures by optimizing the fixture structure, significantly improving electroplating quality and production efficiency, and is suitable for spot plating of precision parts.

[0047] Finally, it should be noted that the above are merely preferred embodiments of the present utility model and are not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features.
