Description

Technical Field

[0001] This application relates to the field of electroplating technology, and in particular to an electroplating fixture for plastic parts with good stability. Background Technology

[0002] When a product is to be electroplated, it needs to be clamped on an electroplating rack, and then the electroplating rack and the product to be electroplated are placed into the electroplating device for electroplating. In the existing electroplating process, in order to make the electroplating layer on the surface of the workpiece uniform, it is usually necessary to rotate the electroplating rack so that the workpiece and the electroplating solution can form a larger area of ​​exchange.

[0003] However, due to the irregular structure of the hanger and the shape limitations of the electroplating tank, the rotating workpiece cannot form a stable convection with the electrolyte, which cannot guarantee the stable processing of the electroplated layer. In response to the above-mentioned related technologies, the applicant proposes an electroplating hanger that can enable stable convection between the workpiece and the electroplating solution, thereby enhancing the stability of the electroplating layer processing. Utility Model Content

[0006] An electroplating fixture for plastic parts with good stability includes a bracket with a connecting elbow at the top. Below the bracket, vertically spaced outward-extending clamping structures are fixed. Inside the clamping structures are jet structures respectively fixed to the bracket and facing the openings of the clamping structures. The jet structures are vertically connected, and at the top of each jet structure is a pump structure fixed to one side of the bracket. The pump structure includes a pump connected to the jet structures, fixed to the top of the bracket. One power supply side of the pump is fixed and electrically connected to the connecting elbow, while the other side extends upward to form a downward-bending power elbow. A closed loop is formed between the power elbow and the connecting elbow.

[0007] By adopting the above technical solution, a jetting structure is set on the inner side of the clamping structure and its vertical connection is ensured, which can realize the uniform spraying of electroplating solution. This helps to ensure stable convection between electroplating solution and workpiece during the electroplating process, so that the coating on the surface of the electroplated part is uniform. The hanging elbow and the power elbow cooperate with each other to make the hanger more stable. The electroplating solution can be continuously and stably sprayed onto the surface of plastic parts, reducing the rework rate caused by uneven supply of electroplating solution and further improving production efficiency.

[0008] Preferably, the pump flow structure further comprises a liquid inlet pipe, a positive contact and a negative contact, the liquid inlet pipe is communicated with the liquid inlet side of the pump machine at one end and extends downward to be fixed to the bottom end of the hanger; the positive contact is electrically connected to the pump machine and extends upward to be fixed to the side wall of the hanger elbow; the negative contact is electrically connected to the pump machine and extends upward, and the power elbow is fixed to the top end of the negative contact.

[0009] By adopting the technical scheme, the negative contact is electrically connected to the pump machine and extends upward, and the power elbow is fixed to the top end of the negative contact, thereby forming a closed and stable circuit loop, and the negative contact forms a hanger position, and the stable hanger is integrated.

[0010] Preferably, the clamping structure comprises clamping supports and clamps, and the clamping supports are vertically layered and fixed to the hanger; the clamps are respectively fixed to the outer edges of the clamping supports and are provided with elastic openings.

[0021] The present application will be further described in detail below with reference to the accompanying drawings.

[0022] This application discloses an electroplating fixture for plastic parts with good stability, referring to... Figure 1 , 2 It includes a bracket 1, with a hanging elbow 2 at the top of the bracket 1. The hanging elbow 2 can be hung on the sliding equipment, and the external power supply is transmitted to the bracket 1 through the hanging elbow 2.

[0023] Reference Figure 2 , 3 , refer to Figure 1 Below the hanger 1, there are vertically spaced clamping structures 3 extending outward. The clamping structure 3 includes a clamping bracket 31 and a clamp 32. The clamps are arranged vertically in layers and fixed to the hanger 1. The clamps 32 are fixed to the outer edge of the clamping bracket 31 and have elastic openings so that the workpiece can be clamped and fixed by the clamps 32.

[0024] Reference Figure 2 , 3 The clamping structure 3 is provided with a jetting structure 4, which includes an annular connecting pipe 41 and a nozzle 42. The annular connecting pipe 41 is respectively corresponding to and fixed to the clamping bracket 31, and adjacent annular connecting pipes 41 are vertically connected to each other. The annular connecting pipe 41 at the top is fed with electroplating solution through the pumping structure 5.

[0025] Reference Figure 2 , 3 The pump flow structure 5 also includes a pump 51, an inlet pipe 52, a positive contact 53, and a negative contact 54. The pump 51 is fixed to the top of the bracket 1. One end of the inlet pipe 52 is connected to the inlet side of the pump 51 and extends downward to be fixed to the bottom of the bracket 1. The annular connecting pipe 41 at the top is connected to the inlet end of the pump 51. The positive contact 53 is electrically connected to the pump 51, extends upward and is fixed to the side wall of the hanging elbow 2. The negative contact 54 is electrically connected to the pump 51 and extends upward.

[0026] Reference Figure 2 , 3The power elbow 6 extends upward to form a downward bending power elbow 6. The power elbow 6 and the hanging elbow 2 form a closed loop, so that the bracket 1 starts at the same time as the electroplating tank is energized, and the pump 51 starts pumping liquid. The hanging elbow 2 and the power elbow 6 are set in parallel to each other, so that the bracket 1 increases the number of hanging points and improves stability.

[0027] Reference Figure 2 , 3 The nozzles 42 are spaced apart on the annular connecting pipes 41 and open laterally toward the clamp 32. The electrolyte is sprayed onto the workpiece through the nozzles 42 to provide a stable and sufficient amount of ions. The nozzles 42 are inclined in the same direction in the horizontal direction, and the electrolyte forms a circumferential circulation in the same direction in the electroplating tank to avoid the generation of turbulence.

[0028] The working process of this application is as follows: the hanging elbow 2 and the power elbow 6 are hung together on the mobile platform. As the hanger 1 is immersed in the electroplating tank, the mobile platform is powered on. The hanging elbow 2 forms a circuit with the workpiece and the electroplating tank for electroplating. The power elbow 6 and the hanging elbow 2 form a circuit. The pump 51 pumps the electrolyte. The electrolyte is continuously sprayed toward the workpiece through the inlet pipe 52, so that the electroplating solution at the workpiece circulates well, thereby achieving a stable electroplating effect.

[0029] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
