Description

Technical Field

[0001] This utility model relates to the field of spot plating anode plate technology, and more specifically, to a split-type spot plating anode plate. Background Technology

[0002] In the field of spot plating technology, the anode plate is the core component for achieving precise local plating. However, its existing structure has obvious defects. Currently, spot plating anode plates are either integral, with poor adaptability, requiring the replacement of the entire anode plate when changing different workpieces, resulting in high cost and low efficiency, or traditional split-welded types, lacking a standard assembly and positioning structure, making splicing prone to misalignment, affecting plating accuracy, and resulting in low yield. At the same time, the traditional anode plate spray hole processing accuracy is low, with large hole diameter tolerances and uneven hole positions, leading to uneven electrolyte spraying, unbalanced current distribution on the workpiece surface to be plated, large differences in plating thickness, and easy occurrence of pinholes, peeling, etc. In addition, the internal stress generated during the processing of the anode plate is difficult to release. Integral types are prone to warping and cracking, while split-welded types are prone to corrosion and leakage at the weld joints, resulting in short service life. There are also problems such as inconvenient assembly and maintenance and long downtime, making it difficult to meet the requirements of high-precision spot plating. Therefore, we propose a split-type spot plating anode plate to solve the above problems. Utility Model Content

[0003] The main objective of this invention is to provide a split-type spot plating anode plate, which solves the problems of current spot plating anode plates, which are either integral, have poor adaptability, require replacing the entire anode plate when changing different workpieces, resulting in high cost and low efficiency, or are traditional split-welded types, which lack a standard assembly and positioning structure, are prone to misalignment during splicing, affect the plating accuracy, and have a low yield. At the same time, traditional anode plates have low processing accuracy of spray holes, large hole diameter tolerances, and uneven hole positions, resulting in uneven electrolyte spraying, unbalanced current distribution on the workpiece to be plated, large differences in plating thickness, and easy occurrence of pinholes, peeling, etc. In addition, the internal stress generated during the processing of the anode plate is difficult to release, integral types are prone to warping and cracking, and the weld joints of split-welded types are prone to corrosion and leakage, resulting in short service life. They also have the problems of inconvenient assembly and maintenance, long downtime, and difficulty in meeting the requirements of high-precision spot plating.

[0004] To achieve the above objectives, the technical solution adopted by this utility model is as follows:

[0005] A split-type spot plating anode plate includes two anode plate bodies. Each anode plate body has a locking groove inside. Each anode plate body has several spray holes and several fixing holes. Each locking groove has a clamping frame installed at its rear end. Each locking groove has several release grooves running through it.

[0006] Preferably, each of the injection holes is opened on the front surface of the anode plate body, and each injection hole is linearly distributed at equal intervals along the crossing direction of the anode plate body.

[0007] Preferably, the release grooves are all elongated strip-shaped structures.

[0008] Preferably, each of the fixing holes is provided at the upper and lower ends of the front surface of the anode plate body, each of the fixing holes is located between the injection holes, and each of the fixing holes is provided with threads inside.

[0009] Compared with the prior art, the present invention has the following beneficial effects:

[0010] (1) The present invention adopts a split structure in which two anode plate bodies cooperate with the clamping frame. The anode plate body is assembled with the clamping frame through the locking groove of the anode plate body to form a standardized positioning structure, avoiding the splicing offset problem of traditional split welding type, ensuring the coating accuracy and yield rate. At the same time, there is no need to replace the anode plate as a whole. When adapting to different workpieces, only a single anode plate body needs to be adjusted or replaced, reducing equipment investment costs, shortening tooling change time, and improving production efficiency.

[0011] (2) In this utility model, the uniformity of electrolyte spraying is improved and the coating quality is ensured to be stable: the spray holes on the front surface of the anode plate are linearly distributed at equal intervals along the length direction. Compared with the traditional spray hole processing accuracy and uneven hole position, the electrolyte can be sprayed evenly onto the surface to be plated, avoiding current distribution imbalance, reducing coating thickness difference, reducing the probability of defects such as pinholes and peeling, and meeting the requirements of high-precision spot plating for coating consistency.

[0012] (3) The long strip-shaped release groove that runs through the card slot in this utility model can effectively release the internal stress generated during the processing of the anode plate, avoid the problems of easy warping and cracking of the integral anode plate and easy corrosion and leakage at the weld joint of the traditional split welding type, extend the service life of the anode plate, and reduce the cost loss caused by frequent replacement.

[0013] (4) The threaded fixing holes at both ends of the front surface of the anode plate body in this utility model, located between the injection holes, facilitate quick assembly and fixing. During maintenance, damaged individual parts, such as blocked injection holes or worn fixing structures, can be repaired and replaced locally without replacing the whole unit, thus shortening equipment downtime and ensuring continuous operation of the production line.

[0018] The technical solutions of this utility model will be clearly and completely described below with reference to the embodiments of this utility model. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of this utility model.

[0019] like Figures 1 to 3 As shown, this utility model embodiment proposes a split spot plating anode plate, including two anode plate bodies 1. Each anode plate body 1 has a locking groove 2 inside. Each anode plate body 1 has a plurality of spray holes 3 and a plurality of fixing holes 4. Each locking groove 2 has a clamping frame 6 installed at the rear end inside. Each locking groove 2 has a plurality of release grooves 5 passing through it.

[0020] like Figures 1 to 3 As shown, in another embodiment of the present invention, each injection hole 3 is opened on the front surface of the anode plate body 1, and each injection hole 3 is linearly distributed at equal intervals along the crossing direction of the anode plate body 1. The release grooves 5 are all elongated structures. Each fixing hole 4 is respectively provided at the upper and lower ends of the front surface of the anode plate body 1. Each fixing hole 4 is located between the injection holes 3, and each fixing hole 4 is provided with threads inside.

[0021] The two anode plate bodies 1 are precisely fixed to the external spot plating equipment bracket through the fixing holes 4 to ensure the relative position of the anode plate body 1 and the workpiece to be plated is stable. Then, the two anode plate bodies 1 are standardized and positioned by the matching engagement groove 2 and the clamping frame 6 to form a complete anode structure. During the spot plating operation, the external electrolyte delivery system sprays the electrolyte into the workpiece to be plated in a directional and uniform manner through the spray holes 3 that are linearly distributed at equal intervals along the length of the front surface of the anode plate body 1. At the same time, the external power supply forms a current loop through the anode structure to complete the local precise plating deposition. During the entire processing and use, the long strip-shaped release groove 5 inside the engagement groove 2 releases the internal stress generated by the anode plate body 1 in real time to ensure structural stability.

[0022] The threaded fixing hole 4 enables a quick and secure connection between the anode plate body 1 and the equipment bracket, avoiding installation offset problems caused by traditional non-standard connectors, ensuring uniform gap between the anode plate body 1 and the workpiece surface to be plated, providing a foundation for subsequent plating accuracy, while simplifying the assembly process and shortening the installation and debugging time of a single anode plate body 1.

[0023] The spray holes 3 are linearly distributed at equal intervals along the length of the anode plate body 1. Compared with the traditional spray holes with large diameter tolerance and uneven hole position, the electrolyte can uniformly cover the workpiece surface to be plated, avoid current distribution imbalance, reduce coating thickness difference, reduce the probability of defects such as pinholes and peeling, and meet the requirements of high-precision spot plating for coating consistency.

[0024] The elongated release groove 5 can effectively release the internal stress generated by the anode plate body 1 during processing and use, avoid the problems of easy warping and cracking of integral anode plates and easy corrosion and leakage at the weld joints of traditional split welded anode plates, extend the service life of the anode plate body 1, and reduce the cost loss caused by frequent replacement.

[0025] The anode plate body 1 is made of pure titanium, titanium alloy, or titanium-based material with platinum or iridium plating on the surface, and the clamping frame 6 is made of high-strength aluminum alloy or stainless steel.

[0026] The working principle of this type of split-type spot plating anode plate:

[0027] In use, the two anode plate bodies 1 are first precisely fixed to the external spot plating equipment bracket through the fixing holes 4 to ensure the relative position of the anode plate body 1 and the workpiece surface to be plated is stable. Then, the two anode plate bodies 1 are standardized and positioned by the matching engagement groove 2 and the clamping frame 6 to form a complete anode structure. During the spot plating operation, the external electrolyte delivery system sprays the electrolyte into the workpiece area to be plated in a directional and uniform manner through the spray holes 3 that are linearly distributed at equal intervals along the length of the front surface of the anode plate body 1. At the same time, the external power supply forms a current loop through the anode structure to complete the local precise plating deposition. During the entire processing and use, the long strip-shaped release groove 5 inside the engagement groove 2 releases the internal stress generated by the anode plate body 1 in real time to ensure structural stability.

[0028] Obviously, the above embodiments of this utility model are merely examples for clearly illustrating this utility model, and are not intended to limit the implementation of this utility model. For those skilled in the art, other variations or modifications can be made based on the above description. It is impossible to exhaustively list all the implementation methods here. Any obvious variations or modifications derived from the technical solutions of this utility model are still within the protection scope of this utility model.
