Structure of pipe-position-free PCB vacuum adsorption gong appearance

A pipe-position-free PCB vacuum adsorption gong appearance structure is used in the field of pipe-position-free PCB machining and comprises an auxiliary base plate, the auxiliary base plate comprises a full-breathable base plate and a non-breathable base plate, the auxiliary base plate is installed between a gong machine vacuum suction table top and a to-be-machined pipe-position-free PCB, and the full-breathable base plate and the non-breathable base plate are arranged on the gong machine vacuum suction table top. A plurality of auxiliary base plate vacuum holes are formed in the non-breathable base plate, large jointed board outer pipe position holes are formed in the corresponding positions of the pipe-position-free PCB and the non-breathable base plate, and the same pipe position nail is inserted into the two large jointed board outer pipe position holes. According to the utility model, not only is the problem that the PCB unit board is shifted, deviated and damaged due to insufficient suction force cause
