[0002] During the manufacturing process of circuit boards, they need to go through a "wet process", which mainly involves cleaning the surface of the circuit board with chemical liquids.

[0003] The copper plating process of PCB board is an important step in the wet process. First, the surface of PCB is cleaned to remove oil, oxides and other impurities; after the surface preparation is completed, a layer of activator is applied. The activator can form a metal ion adsorption layer on the surface of PCB, which is conducive to the adsorption and deposition of copper ions in the subsequent chemical copper plating solution; the treated PCB is placed in the chemical copper plating tank. The chemical copper plating solution forms a uniform copper layer on the surface of PCB through an external current. Usually, multiple horizontally arranged upper and lower rollers are set on the top of the copper plating tank, and the PCB board passes between the upper and lower rollers.

[0004] Due to the limitation of copper solution ingredients, the whole equipment cannot be made of metal. In the prior art, the copper tank conveying roller group adopts FRP material axis. In order to facilitate disassembly and assembly, multiple LDPE material rollers are assembled on the axis, and two adjacent rollers are connected by bayonet. Because the roller and the axis are loosely matched, during the production process, the gap between the roller and the bayonet and the gap between the roller and the axis are easy to deposit the solution, resulting in copper deposition, which affects the copper solution.
