SMT Automatic Destacker Loader Machine (also known as a layer-stacking board feeder or automatic board feeder) is a core automated device primarily used for front-end board feeding operations in SMT (Surface Mount Technology) production lines, enabling efficient automatic transmission and stacking of bare PCBs. Its primary function is to replace manual labour with automated mechanisms, feeding stacked PCB blanks one by one into the production line track to ensure smooth production workflow. Specifically, after receiving signals from downstream equipment (such as pick-and-place machines or printers), it uses push plate cylinders or conveyor belt mechanisms to precisely drop or push PCB boards onto the transmission track, eliminating the cumbersome manual stacking process.
