[0002] The tinning line is a production line specially used for plating a layer of tin on the metal surface. This production line usually consists of multiple equipment and process steps to achieve the entire process from metal pretreatment to final tinning. In the tinning production line, the metal surface must first be pretreated, including cleaning, degreasing, rust removal and other steps to ensure the cleanliness and smoothness of the metal surface, thereby improving the tinning effect. Next, the metal parts will be sent to the electroplating equipment, which is the core part of the production line. The electroplating equipment usually includes a tinning tank and corresponding power supply equipment, control system, etc. The metal parts are immersed in the tinning solution by rack plating or barrel plating. The tin ions are reduced to a metal coating on the metal surface by the action of electric current, forming a uniform and dense tin layer.
[0003] At present, when electroplating the surface of an electroplated part, in order to electroplate a part of the surface of the electroplated part and the electroplated part has a certain length, the electroplated part will be slid and the surface will be in contact with the plating liquid in the plating tank for electroplating. However, when the electroplated part slides out of the plating tank, part of the plating liquid will drip onto the ground, resulting in the need to clean the plating liquid later, which also results in a certain amount of waste. Therefore, a tin plating production line that can accurately control the height of the plating layer is proposed. Utility Model Content
