The invention belongs to the technical field of circuit board gold immersion and
sand blasting, and particularly relates to a circuit board gold immersion and
sand blasting device which comprises a rack and two groups of chains, two groups of transmission shafts are rotationally arranged in the rack, two groups of chain wheels are mounted on the transmission shafts, each group of chain is meshed with the two groups of chain wheels, a plurality of groups of discharging assemblies are arranged around the chains, and a
sand blasting mechanism is arranged above the rack. The sand blasting mechanism comprises a transparent cover, side plates are fixed to the two ends of the transparent cover, the lower ends of the side plates are fixedly connected with the
machine frame, the lower ends of the side plates are provided with material passing grooves used for allowing the discharging
assembly to pass through, and the discharging
assembly is provided with rectangular grooves. A
closed space is formed by the multiple sets of discharging assemblies, the two sets of side plates, the transparent cover, the two sets of sealing edge strips and the dustproof filter bag, and frosted sand splashed in the
closed space only falls into the dustproof filter bag, so that the situation that the frosted sand splashes to the outside is greatly reduced, waste of the frosted sand is reduced, and meanwhile
pollution of the frosted sand to the external environment is greatly reduced.
