A suction roller device

Abstract

The invention relates to the technical field of water washing equipment for circuit boards and discloses a water suction windlass device used for extruding, sucking and etching liquid on the circuit board. The water suction windlass device comprises an isolation groove, a stand firmly arranged in the isolation groove, a water suction windlass group arranged on the stand and used for extruding and sucking the liquid on the circuit board, and a transmission device arranged on the stand and used for driving the water suction windlass group to rotate axially, and moreover, the stand is provided with a water press windlass for extruding the water suction windlass group, an angle is formed between the water press windlass and the water suction windlass group, and spiral water extrusion threads are formed in the outer wall of the water press windlass. According to the water suction windlass device, the water press windlass with water extrusion threads is arranged at the oblique upper side of the water suction windlass group, the water suction windlass group is extruded through the water press windlass, the liquid sucked by the water suction windlass group is extruded towards the two ends through the water extrusion threads, the post-liquid taking phenomenon is reduced, the energy saving and emission reduction demands are satisfied, the circuit board surface oxidization chance is reduced, and the circuit board quality is improved.

Description

technical field [0001] The invention relates to the technical field of circuit board water washing section equipment, in particular to a water suction roller device. Background technique [0002] At present, my country's environmental protection requirements are becoming more and more stringent, especially for high-pollution industries such as circuit boards, it is very important to improve the energy-saving and emission-reduction performance of their production equipment. At the same time, the process potions of some circuit boards are very expensive, such as black holes, palladium cylinders, etc. These potions basically account for 90% of the cost of potions on a production line. How to reduce the introduction of potions and improve the service life of potions is also Issues of major concern to the industry.

AI Technical Summary

Problems solved by technology

refer to figure 1 and figure 2 , the traditional water suction roller device presses the pressing block 4' to the two ends of the upper water suction roller 31' through the adjusting screw 2' above the frame 1', so that the upper water suction roller 31' squeezes the lower water suction roller 32', In order to achieve the purpose of squeezing away the water or potion on the surface of the circuit board, but there are certain defects in this method: due to the reason of the pool, the middle part of the upper surface of the circuit board will have more water or potion than its two ends. During continuous production, the middle position of the circuit board contains a lot of water, so that the water-absorbing roller 2' cannot completely absorb the surface of the circuit board, resulting in serious after-tasting of the potion, which not only wastes the potion, but also easily causes the circuit board to break down. Oxidation affects the quality of the circuit board
