Description

Technical Field

[0001] This utility model relates to the field of infrared coating electroplating technology, specifically, an electroplating device for infrared coating of multiple parts in one tank. Background Technology

[0002] With the research and development in the field of infrared stealth, infrared coating preparation technologies have diversified. Among them, electroplating technology is widely used in the preparation of infrared coatings due to its advantages such as low cost and high efficiency. However, the electroplating process often suffers from problems such as uneven coating, difficulty in eliminating side reactions such as hydrogen evolution and bubble adhesion, and cumbersome anode plate replacement. The combination of these problems leads to unstable performance of precision electroplated products, resulting in product failures such as uneven coating thickness and pitting caused by hydrogen evolution side reactions, which seriously reduces the performance and durability of precision electroplated products.

[0003] In view of this, this utility model is hereby proposed. Utility Model Content

[0014] In the diagram, 1 is the electroplating tank; 2 is the anode mechanism; 21 is the anode wire; 22 is the anode plate; 3 is the cathode mechanism; 31 is the cathode wire; 32 is the cathode hook; 4 is the bubbling mechanism; 41 is the main air pipe; 42 is the branch air pipe; 43 is the check valve; and 5 is the power supply. Detailed Implementation

[0015] The present invention will now be described in detail with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of the present invention, and not all of them. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without creative effort are within the protection scope of the present invention.

[0016] refer to Figure 1 This utility model provides an electroplating device for infrared coating of multiple parts in one tank, including a power supply 5. The positive terminal of the power supply 5 is connected to an anode mechanism 2, and the negative terminal of the power supply 5 is connected to a cathode mechanism 3. The anode mechanism 2 and the cathode mechanism 3 are connected through an electroplating tank 1. A bubbling mechanism 4 is provided at the bottom of the electroplating tank 1.

[0017] Based on the above structure, the anode mechanism 2 is fixedly connected to the positive terminal of the power supply 5 via an anode wire 21. The anode mechanism 2 also includes several anode plates 22 arranged at intervals, preferably eight in number. The upper end of each anode plate 22 is fixedly connected to the anode wire 21 via an anode rod, and the lower end of the anode plate 22 is inserted into the electroplating tank 1, which promotes the formation of a coating layer on the surface of the part by ions in the electroplating solution. This achieves uniform voltage distribution and avoids the problem of uneven coating thickness during the electroplating process. The anode rod and the anode plate 22 are connected by a vertical rod, and the vertical rod and the anode plate 22 are hinged together. Through the vertical rod, the anode plate 22 can rotate, rise, and fall according to the size and shape of the part, making it easy to adjust the size ratio between the cathode and the anode.

[0018] On the other hand, the cathode mechanism 3 is fixedly connected to the negative terminal of the power supply 5 through the cathode wire 31, forming a closed loop with the anode mechanism 2. The cathode mechanism 3 also includes a number of cathode hooks 32 arranged at intervals. The number of cathode hooks 32 is the same as the number of anode plates 22, preferably 8. They are fixedly connected to the cathode wire 31 through the cathode rod. The cathode hooks 32 are used to suspend electroplated parts.

[0019] To promote the flow of plating solution, replenish the concentration of plating solution near the parts, and remove impurities and bubbles attached to the surface of the parts, the bubbling mechanism 4 includes a main air pipe 41. The main air pipe 41 is connected to the bottom of the electroplating tank 1 through several branch air pipes 42. Adjusting the appropriate air volume can promote the replenishment of the concentration of plating solution near the parts and eliminate the pitting caused by bubbles due to side reactions. The uniformly designed air pipe can uniformly bubble and avoid pitting problems on the surface of the parts caused by side reactions such as hydrogen evolution.

[0020] Specifically, the electroplating tank 1 is provided with electroplating solution, preferably in a narrow and long shape, which helps to reduce the amount of electroplating solution required for electroplating and can save costs for precious metal electroplating. The bottom of the electroplating tank 1 is also provided with several openings evenly spaced for communication with the branch pipe 42. A check valve 43 is provided at the connection between the branch pipe 42 and the electroplating tank 1, which can improve the stability of the device and prevent the plating solution from flowing back.

[0021] The working principle of an electroplating device for infrared coating of multiple parts in one tank is as follows:

[0022] When electroplating an infrared coating, pour an appropriate amount of electroplating solution into the electroplating tank 1, adjust the position and size ratio of the anode plate 22, suspend the part on the cathode mechanism 3 through the cathode hook 32, start the bubbling mechanism 4, adjust to the appropriate air volume, turn on the power supply 5, set the required electroplating parameters, and perform infrared coating electroplating.

[0023] The above description is merely a specific embodiment of this utility model, enabling those skilled in the art to understand or implement it. Various modifications to these embodiments will be readily apparent to those skilled in the art, and the general principles defined herein may be implemented in other embodiments without departing from the spirit or scope of this utility model.

[0024] It should be understood that this utility model is not limited to the content already described above, and various modifications and changes can be made without departing from its scope. The scope of this utility model is limited only by the appended claims.
