Description

Technical Field

[0001] The utility model belongs to the technical field of cleaning water-absorbing rollers for printed circuit boards, in particular to a device for cleaning water-absorbing rollers for printed circuit boards. Background Art

[0002] The PCB printing water absorption roller, also known as the sponge rod, is an important tool used in the PCB printing process. It is made of PVA foam sponge with high-density hydrophilic molecules. It has the characteristics of interconnected micropores, so it has excellent water absorption performance, which can reach 6 to 10 times its own dry weight. In addition, the water absorption roller also has the advantages of fast drying, corrosion resistance, good elasticity, and will not scratch the surface of objects.

[0003] In the prior art, the suction roller is connected to a rotating assembly and rotates as a whole. Its absorbent sponge can absorb the residual liquid on the surface of the printed circuit board and perform a drying process. When the absorbent sponge is saturated, in order to ensure the water absorption effect of the suction roller, the water will be squeezed out of the inside of the suction roller to clean and dehydrate the suction roller.

[0004] During long-term use and observation, it was found that the existing circuit board printing water suction roller cleaning device squeezes out the water inside the water suction roller through friction. After repeated friction and squeezing, the surface of the water suction roller will wear out, resulting in insufficient contact with the circuit board, affecting the water absorption effect of the water suction roller on the circuit board.

[0005] To this end, the utility model provides a device for cleaning a printed circuit board water-absorbing roller. Utility Model Content
