Description

Technical Field

[0001] This utility model relates to an electroplating fixture, and more particularly to an electroplating fixture with a four-way sacrificial electrode. Background Technology

[0002] A sacrificial electrode is a device that protects other metals from electrochemical corrosion by corroding itself. It is a component of cathodic protection technology. Its core principle is to use electrochemical preferential reaction to replace the corrosion of the protected metal. It is widely used in the electroplating of components such as circuit boards.

[0003] Generally, when sacrificial electrodes are used in electroplating fixtures, they are mounted on the side or bottom. When the sacrificial electrode is mounted on the bottom, its shape must be modified in order to avoid the clamps mounted on the load.

[0004] However, the existing installation method has the following drawbacks: a single-sided or unidirectional sacrificial electrode may cause uneven distribution of protective current, and some areas may still be corroded due to insufficient current; secondly, unidirectional current will cause the adjacent anode to be consumed too quickly and the utilization rate of the far anode to be low. In addition, unidirectional current is easily affected by environmental interference, which may lead to protection failure. Therefore, the existing installation of sacrificial electrodes cannot meet the usage requirements. Utility Model Content

[0005] The purpose of this invention is to overcome the shortcomings of the prior art by providing a plating fixture with four-directional sacrificial electrodes, which enables the current energy to be evenly distributed in four directions, resulting in high product quality.

[0006] To achieve the above objectives, the technical solution adopted by this utility model is: a plating fixture with a four-directional sacrificial electrode, comprising:

[0007] Mounting base;

[0008] A frame, which is vertically mounted on the mounting base, has a hollow interior.

[0009] A left sacrificial electrode and a right sacrificial electrode, wherein the left sacrificial electrode and the right sacrificial electrode are respectively disposed at the left end and the right end of the hollow interior of the frame;

[0010] The lower sacrificial electrode is disposed at the bottom of the hollow interior of the frame;

[0011] The upper sacrificial electrode is slidably mounted on the top of the hollow frame via a sliding assembly; the left, right, lower, and upper sacrificial electrodes together form a placement space that can generate uniformly distributed current energy around the perimeter.

[0012] Furthermore, the sliding assembly includes a slide rail extending downward into the hollow of the frame from the upper end of the frame; a slider is provided on the slide rail; the slider is connected to the upper sacrificial electrode located between the left and right sacrificial electrodes via a connecting strip.

[0013] Furthermore, the left and right sacrificial electrodes are respectively arranged along the length of the left and right sides of the hollow frame, and the left and right sacrificial electrodes are L-shaped.

[0014] Furthermore, the lower sacrificial electrode is arranged along the length direction of the bottom of the frame, and the two ends of the lower sacrificial electrode do not contact the left sacrificial electrode and the right sacrificial electrode.

[0015] Furthermore, the left sacrificial electrode, right sacrificial electrode, upper sacrificial electrode, and lower sacrificial electrode are made of zinc or copper.

[0016] Due to the application of the above technical solution, this utility model has the following advantages compared with the prior art:

[0017] This utility model discloses an electroplating fixture with four-directional sacrificial electrodes. Upper sacrificial electrodes, lower sacrificial electrodes, left sacrificial electrodes, and right sacrificial electrodes are respectively arranged on the top and bottom, and left and right sides of the frame. Simultaneously, the upper sacrificial electrode can move up and down via a sliding assembly to avoid clamp interference. This allows the current energy generated within the frame to be evenly distributed in four directions, preventing localized corrosion of the product and resulting in a better electroplating effect. All anodes corrode simultaneously, avoiding localized overload, while also reducing energy consumption and optimizing current efficiency, thus better meeting practical electroplating requirements.

[0023] To enable those skilled in the art to better understand the present application, the technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present application, and not all embodiments. Based on the embodiments in the present application, all other embodiments obtained by those of ordinary skill in the art without creative effort should fall within the scope of protection of the present application.

[0024] This invention provides an electroplating fixture with a four-way sacrificial electrode to solve the problems in the prior art where the sacrificial electrode is installed on one side or at the bottom, which may lead to uneven distribution of protective current, low utilization of the far-end anode, and susceptibility of unidirectional current to environmental interference.

[0025] For ease of understanding, the specific processes in the embodiments of this application are described below. Please refer to [link / reference]. Figures 1 to 3 An electroplating fixture with four-way sacrificial electrodes according to an embodiment of this application includes a mounting base 1, a frame 2, a left sacrificial electrode 3, a right sacrificial electrode 4, a lower sacrificial electrode 5, and an upper sacrificial electrode 6. The frame 2 is vertically disposed below the mounting base 1, and the interior of the frame 2 is hollow. The left sacrificial electrode 3 and the right sacrificial electrode 4 are respectively disposed at the left and right ends of the hollow interior of the frame 2. The lower sacrificial electrode 5 is disposed at the bottom of the hollow interior of the frame 2. The upper sacrificial electrode 6 is disposed at the top of the hollow interior of the frame 2 via a sliding assembly 7. The left sacrificial electrode 3, the right sacrificial electrode 4, the lower sacrificial electrode 5, and the upper sacrificial electrode 6 form a placement space that can generate uniformly distributed current energy around its perimeter.

[0026] This invention uses a left sacrificial electrode 3, a right sacrificial electrode 4, a lower sacrificial electrode 5, and an upper sacrificial electrode 6 to create a uniformly distributed current around the perimeter. This ensures that the product within the placement space receives the current evenly, preventing localized corrosion and ensuring a stable and reliable electroplating process.

[0027] For further details, please refer to [link / reference]. Figure 1 In this embodiment, the upper sacrificial electrode 6 is slidably disposed above the frame 2 via a sliding assembly 7. Specifically, the sliding assembly 7 is mounted on the top of the frame 2. After the upper sacrificial electrode 6 is driven to move up and down via the sliding assembly 7, it can avoid interference from the clamps in the electroplating fixture during loading, facilitating actual installation and use.

[0028] For further details, please refer to [link / reference]. Figure 1 and Figure 3The sliding assembly 7 includes a slide rail 70 extending downwards from the upper end of the frame 2 into the hollow space of the frame 2; a slider 71 is provided on the slide rail; the slider 71 is connected to the upper sacrificial electrode 6 located between the left sacrificial electrode 3 and the right sacrificial electrode 4 via a connecting strip 72. When it is necessary to adjust the vertical position of the upper sacrificial electrode 6, the slider 71 drives the upper sacrificial electrode 6 to move up and down above the lower sacrificial electrode 5 via the connecting strip 72, thereby adjusting the size of the placement space to accommodate different products while avoiding interference from the clamps. Since the clamps are also installed on the upper end of the frame, the product can be clamped by the clamps first, and then the product can be moved down by the sliding assembly 7.

[0029] For further details, please refer to [link / reference]. Figure 3 The left sacrificial electrode 3 and the right sacrificial electrode 4 are respectively arranged along the length of the left and right sides of the hollow frame 2, so that current energy can be generated on the left and right sides of the frame 2 respectively. In this embodiment, the left sacrificial electrode 3 and the right sacrificial electrode 4 are both L-shaped, which facilitates actual installation and use.

[0030] For further details, please refer to [link / reference]. Figure 3 The lower sacrificial electrode 5 is arranged along the length of the bottom of the frame 2, and the two ends of the lower sacrificial electrode 5 do not contact the left sacrificial electrode 3 and the right sacrificial electrode 4. This non-contact arrangement can prevent the two from affecting each other.

[0031] Furthermore, the left sacrificial electrode 3, right sacrificial electrode 4, upper sacrificial electrode 6, and lower sacrificial electrode 5 are made of zinc or copper, which have good conductivity and can meet the actual use requirements. Of course, other materials can also be used as long as they meet the requirements of this utility model.

[0032] In actual operation, the product is placed into the electroplating solution after passing through this electroplating fixture. At this time, the product is located in the placement space. Since the upper sacrificial electrode, lower sacrificial electrode, left sacrificial electrode, and right sacrificial electrode are respectively set on the top, bottom, left, and right sides of the frame, the generated current energy can be evenly distributed in four directions, avoiding local "underprotection". All anodes are corroded simultaneously, avoiding local overload, reducing energy consumption, optimizing current efficiency, and achieving excellent electroplating quality, which well meets the electroplating requirements.

[0033] The above-described embodiments are only used to illustrate the technical solutions of this application, and are not intended to limit them. Although this application has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the spirit and scope of the technical solutions of the embodiments of this application.
