Description

TECHNICAL FIELD

[0002] The ring-shaped liftable electroplating production line is favored by more and more users due to its advantages of high stability and small size. For example, a vertical electroplating production line is disclosed in Chinese patent (CN221398114U), which comprises a ring-shaped conveying chain, multiple lifting frames and multiple electroplating tanks. The multiple lifting frames are installed along the outer circumferential direction of the ring-shaped conveying chain, and the multiple electroplating tanks are arranged around the ring-shaped conveying chain. The working process is as follows: the workpiece is clamped and fixed on the hanger, and then moved to the electroplating tank through the ring-shaped conveying chain and the lifting frame. When the horizontal arm is driven to move downward by the lifting frame, the support rod and the clamping rod at the end of the horizontal arm will respectively drive the hanger and the horizontal plate to slide downward into the electroplating tank, and then electroplating is completed in the electroplating tank. After electroplating is completed, the hanger is moved upward by the lifting frame to leave the electroplating tank, and is conveyed to the next station by the ring-shaped conveying chain. Among them, the ring-shaped liftable electroplating production line is provided with a conductive plate on one side of each electroplating tank close to the ring-shaped conveying chain, and the horizontal arm on the lifting frame is provided with a conductive brush. When the lifting frame moves the hanger downward into the corresponding electroplating tank, the conductive brush contacts the conductive plate to supply power to the hanger.

However, when foreign matter falls into the electroplating tank, the electroplating liquid will splash onto the conductive plate, increasing the safety hazard of the ring-shaped liftable electroplating production line.
