Description

Technical Field

[0001] This utility model relates to, but is not limited to, the field of electroplating equipment, and particularly to a spot plating anti-skid tension fixture. Background Technology

[0002] Roll-to-roll electroplating, as a type of continuous electroplating, involves the continuous conveying of a strip of material to complete the spot plating process in an electroplating tank. During this process, tension dies are used to control and maintain the tension and position of the strip on the production line. By applying appropriate tension through the tension dies, the material is ensured to remain flat and stable during the electroplating process, avoiding slack or excessive stretching, thereby ensuring the uniformity of electroplating. The tension dies also guide the strip to run along a predetermined path, preventing deviation or twisting, and ensuring that the material passes accurately through the electroplating tank and other processing areas.

[0003] In the existing terminal spot plating process, problems such as improper tension or mold wear inevitably lead to uneven force on the material strip when it passes through the electroplating tank, and even the material strip jumping out of the tank. This can also prevent some areas of the material strip from fully contacting the electroplating solution, resulting in unplated terminals on the material strip, which seriously affects the production efficiency of the production line.
