Description

PCB loading and unloading machine Technical Field The utility model relates to the technical field of PCB processing, in particular to a PCB feeding and discharging machine. Background The PCB is an electronic board commonly used in our daily life, cutting, polishing and punching positioning operations are needed to be performed on the copper-clad plate in the production process, multi-step operations such as drilling, screen printing, etching, electronic component installation and the like are performed, the positioning holes are drilled for positioning the board, the drilling holes are used for drilling reserved screw holes and mounting holes of the electronic component on the copper-clad plate, after the positioning holes are drilled on the copper-clad plate on a production line and the positioning bolts are mounted, the copper-clad plate is needed to be transferred to CNC equipment for punching operation, and in order to improve the working efficiency, feeding and discharging are needed to be performed by means of a feeding and discharging machine. For example, the patent of CN111747016B discloses an automatic feeding and discharging machine for PCB board, the device uses four groups of conveyor belt mechanisms, a gap is left between two adjacent conveyor belts, which is consistent with the width and thickness of PCB board, so that the kinetic energy of the conveyor belt is convenient to drive the transportation of PCB board, and further automatic feeding and discharging is performed. However, when the device is used for feeding and discharging, the PCB cannot be positioned, so that the PCB can shift during conveying, the conveying effect is affected, feeding and discharging cannot be simultaneously performed, and the processing efficiency of the PCB is reduced. Disclosure of utility model The utility model aims to provide a PCB loading and unloading machine, which aims to solve the problems in the background technology.
