Description

Technical Field

[0001] This utility model relates to the field of electroplating technology, and in particular to an electroplating fixture. Background Technology

[0002] Electroplating is the process of depositing a thin layer of another metal or alloy onto the surface of certain metals using the principle of electrolysis. It is a process that uses electrolysis to attach a metal film to the surface of metal or other material parts, thereby preventing metal oxidation, improving wear resistance, conductivity, reflectivity, corrosion resistance, and enhancing aesthetics.

[0003] However, during the electroplating process, airflow is generated due to chemical reactions. This airflow can cause uneven flow of the electrolyte in the electroplating tank, affecting the uniformity of the coating. Furthermore, air bubbles adhering to the workpiece surface can affect the continuity and integrity of the coating. Therefore, an electroplating fixture is proposed. Utility Model Content

[0004] This utility model addresses the shortcomings of existing technologies by providing the following technical solution:

[0005] An electroplating fixture includes a base plate, on which multiple sets of supports are arranged along the extension direction of the base plate. Multiple sets of baffles are fixedly connected to both sides of the multiple sets of supports, and the multiple sets of baffles block the airflow generated during electroplating in layers.

[0006] During electroplating, chemical reactions within the tank generate airflow, which can lead to uneven electrolyte flow, affecting the uniformity of the plating layer. Furthermore, air bubbles adhering to the workpiece surface can disrupt the continuity and integrity of the plating layer, potentially causing pinholes, pitting, and other defects, as well as uneven thickness, thus impacting plating quality. By sequentially installing multiple baffles along the support's extension direction, the airflow is blocked and managed in layers. This approach partially interrupts the chemical reactions within the electroplating tank, ensuring uniform and stable airflow. This effectively coats the product surface, sequentially preventing turbulent airflow during electroplating and reducing product fluctuations. The baffles also reduce air bubble adhesion to the workpiece surface, improving plating uniformity and integrity. Additionally, the baffles guide electrolyte flow, making it more uniform and reducing electrolyte fluctuations caused by airflow. This addresses electroplating issues stemming from product structure, increasing production yield and reducing production costs.

[0007] As an improvement to the above technical solution, multiple sets of hooks are fixedly installed on the bracket and above the baffle.

[0008] Placing the workpiece on the hook, which is mounted above the baffle, minimizes the impact of airflow on the workpiece.

[0009] As an improvement to the above technical solution, a connecting rod is provided between the baffle and the bracket, and the angle between the connecting rod and the bracket is less than 60°.

[0010] It can increase the stability of the connection structure between the connecting rod and the bracket, disperse and resist the load of the electrolyte on the connecting rod, and improve the overall rigidity.

[0011] As an improvement to the above technical solution, a plurality of guide holes are provided on the baffle plate and along the extension direction of the baffle plate.

[0012] It can stabilize airflow guidance, and the force-relieving design reduces the shaking of electroplating fixtures. At the same time, it can avoid completely blocking the flow of electrolyte, which would lead to insufficient electrolyte on the workpiece surface.

[0013] As an improvement to the above technical solution, the baffle is provided in three sets, and the top of the baffle has a smoothly transitioning inclined surface with an angle of 15°-25°.

[0014] The inclined surface can guide the liquid to flow back into the electrolyte along the surface of the baffle, reducing liquid residue and increasing the durability of the electroplating fixture. At the same time, the inclined surface can reduce the resistance when the baffle moves in the electrolyte, making it easier for the baffle to enter and exit the electrolyte.

[0015] The beneficial effects of this utility model are:

[0016] By sequentially setting multiple baffles along the extension direction of the bracket, layered blocking and airflow can be achieved, partially blocking the chemical reaction within the electroplating tank. This results in uniform and stable airflow within the electroplating tank, effectively coating the product surface. The baffles sequentially prevent turbulent airflow within the electroplating tank during electroplating, thereby reducing product fluctuations. They also reduce the adhesion of bubbles to the workpiece surface, improving the uniformity and integrity of the coating. Furthermore, the baffles guide the flow of the electrolyte, making it more uniform and reducing electrolyte fluctuations caused by airflow. This solves electroplating problems caused by product structure, increases product yield, and reduces production costs. Attached Figure Description

[0020] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present utility model and are not intended to limit the present utility model.

[0021] An electroplating fixture includes a base plate 10, on which multiple sets of supports 20 are arranged along the extending direction of the base plate 10. Multiple sets of baffles 30 are fixedly connected to both sides of the multiple sets of supports 20, and the multiple sets of baffles 30 block the airflow generated during electroplating in layers.

[0022] During electroplating, chemical reactions within the plating tank generate airflow, which can lead to uneven electrolyte flow, affecting the uniformity of the plating layer. Furthermore, air bubbles adhering to the workpiece surface can disrupt the continuity and integrity of the plating layer. These bubbles can also cause defects such as pinholes and pitting, resulting in uneven plating thickness and impacting plating quality. By sequentially installing multiple sets of baffles 30 along the support's extension direction, the airflow is blocked and managed in layers. This partially blocks the chemical reactions within the plating tank, ensuring uniform and stable airflow and effective coating of the product surface. The baffles sequentially prevent turbulent airflow during electroplating, reducing product fluctuations. They also reduce air bubble adhesion to the workpiece surface, improving plating uniformity and integrity. Additionally, the baffles guide electrolyte flow, making it more uniform and reducing electrolyte fluctuations caused by airflow. This addresses electroplating problems stemming from product structure, increasing production yield and reducing production costs.

[0023] In one embodiment, a plurality of hooks 40 are fixedly provided on the support 20 and above the baffle 30. The workpiece is placed on the hooks 40, and the hooks 40 are installed above the baffle 30 to minimize the impact of airflow on the workpiece.

[0024] In one embodiment, a connecting rod 302 is provided between the baffle 30 and the bracket 20. The angle between the connecting rod 302 and the bracket 20 is less than 60°, which can increase the stability of the connection structure between the connecting rod 302 and the bracket 20, disperse and resist the load of the electrolyte on the connecting rod 302, and improve the overall rigidity.

[0025] In one embodiment, a plurality of guide holes 31 are provided on the baffle 30 and along the extension direction of the baffle 30, which can stabilize the airflow and reduce the shaking of the electroplating fixture by the force relief design. At the same time, it can avoid completely blocking the flow of electrolyte, which would lead to insufficient electrolyte on the surface of the workpiece.

[0026] In one embodiment, the baffle 30 is provided in three sets. The top of the baffle 30 has a smoothly transitioning inclined surface 301 with an angle of 15°-25°. The inclined surface 301 can guide the liquid to flow back into the electrolyte along the surface of the baffle 30, reducing liquid residue and increasing the durability of the electroplating fixture. At the same time, the inclined surface 301 can reduce the resistance when the baffle 30 moves in the electrolyte, making it easier for the baffle 30 to enter and exit the electrolyte.

[0027] The above embodiments are only used to illustrate the technical solutions of the present invention, and are not intended to limit it.
