[0022] It should be noted that for the traditional process of copper plating of aluminum foil, stable control of the plating solution temperature is a crucial link to ensure the quality of the coating. The traditional plating solution temperature is difficult to maintain in the optimal range, and the temperature difference of the plating solution causes coating quality defects; external factors such as the ambient temperature, humidity and ventilation conditions in the electroplating workshop may also affect the plating solution temperature, especially in large production lines or open environments. Based on the above, a production device for copper plating of aluminum foil is needed to solve the above problems;

[0023] In this embodiment, the plating tank 1 is the core component of the electroplating process. The plating tank 1 contains the electrolyte required for copper plating. The electroplating anode 2 on its inner wall deposits copper ions on the surface of the aluminum foil through electrolysis to form a plating layer. The bracket 3 is fixedly installed on one side of the plating tank 1 to support and guide the aluminum foil roll 4 to be plated with copper into the plating tank for electroplating. This design ensures the continuous and stable transportation of the aluminum foil; multiple first guide rollers 5 are rotatably installed in the plating tank 1, and their function is to guide the aluminum foil to ensure the smooth operation of the aluminum foil in the plating solution and avoid uneven plating caused by shaking or folding of the aluminum foil; the air supply pipe 10, the heating box 11, the electric heating pipe 12, and the connecting pipe 13: this series of components constitute the plating solution heating system.

The filter plate 18 is made of high-efficiency filter material, which can effectively filter out dust, impurities and other particulate matter in the air, and prevent these pollutants from entering the plating tank and affecting the quality of the coating. At the same time, the removable design facilitates the cleaning and replacement of the filter plate 18, and improves the maintenance efficiency and service life of the equipment; the connecting pipe 19 is fixedly connected to the bottom of the filter box 16, and its function is to communicate with the external environment or other air sources so as to replenish air into the filter box 16 when needed. The design of the connecting pipe 19 takes into account the overall layout of the equipment and the smoothness of air flow, ensuring that the filtering mechanism can work continuously and effectively; through the filtering effect of the filter plate 18, dust, impurities and other particulate matter in the air are effectively removed, and the quality of air entering the fan 14 and the heating box 11 is improved, thereby reducing the impact of these pollutants on the plating solution and the quality of the coating; the filter plate 18 adopts a removable design, which allows users to easily clean and replace the filter plate, reducing the difficulty and cost of equipment maintenance.

The arc groove is designed to facilitate the placement of the roller of the aluminum foil roll; the balls are embedded in the inner wall of the arc groove to form a rolling support surface. The introduction of the balls converts the sliding friction that may have been generated into rolling friction, which greatly reduces the friction resistance between the roller frame of the aluminum foil roll and the bracket 3.

[0032] In a further preferred embodiment of the utility model, support legs are symmetrically fixedly installed on the bottom of the plating tank 1, and a drain pipe is fixedly connected to one side of the plating tank 1, and a valve is provided on the drain pipe.
