The contact between the hook and the test plate prevents the deposition of metal atoms, resulting in uneven distribution of the anti-corrosion layer on the surface of the test plate and reducing the local anti-corrosion effect.
The clamping mechanism driven by a motor, through the cooperation of a lead screw and a connecting plate, achieves uniform clamping of the test board, ensuring that only one side of the clamping mechanism works during the electroplating process, while the other side is completely exposed. The temperature of the electroplating solution is regulated by heating and cooling equipment, and the electroplating gas is treated by a purification box and activated carbon.
The anti-corrosion layer on the test board surface was evenly distributed, which improved the effect of electroplating. Furthermore, the efficiency and quality of the electroplating process were improved through temperature control and gas purification.

Technical Field
[0001] This utility model relates to the field of surface corrosion protection technology, specifically a surface corrosion protection device for test plate processing. Background Technology
[0002] A test board is a hardware carrier used to verify circuit design, functional modules, or system performance. The material selection for the test board depends on the test object. Common types of test boards include phosphated steel plates, untreated standard boards, chromated aluminum plates, tin-plated plates, electrophoretic plates, curved metal plates, stainless steel plates, galvanized plates, and sandblasted plates. The production process of a test board involves a series of processing steps, including anti-corrosion treatment of the material. Electroplating anti-corrosion is a technology that uses electrochemical methods to deposit a metal or alloy coating on a metal surface to provide corrosion protection. Its core lies in using the principle of electrolysis to form a uniform and dense protective layer, which combines anti-corrosion, wear resistance, and decorative functions.
[0003] Chinese Patent Publication No. CN222205549U, authorized on December 20, 2024, discloses a metal surface anti-corrosion treatment device, including an electroplating tank, a frame clamping mechanism, and a grinding mechanism. The device is characterized by an external connection hole for a heat dissipation pipe at the bottom of the electroplating tank, with heat dissipation pipes arranged at the bottom of the tank and their ports installed in the external connection hole. A temperature sensor is installed on the inner wall of the bottom of the electroplating tank. With this design, the operator can determine the temperature of the electroplating solution based on the data from the temperature sensor and, as needed, supply cooling water or hot steam to the heat dissipation pipes through the external connection hole, thereby achieving cooling and heating of the electroplating solution.
[0004] Existing anti-corrosion devices suspend the test board in the electroplating solution by hooking it. The contact between the hook and the test board prevents metal atoms from depositing on the surface of the test board, resulting in uneven distribution of the anti-corrosion layer on the surface of the test board, reducing the anti-corrosion effect on the local surface of the test board, and failing to meet the usage requirements.
