Automatic Destacker Loader And Unloader Machine (also known as the stacking and feeding integrated machine) is an automated integrated device in the SMT production line that combines the functions of feeding (stacking) and collecting boards. Its core function is to achieve the automatic supply of bare PCBs and the efficient collection of finished boards through intelligent mechanical structures. Core Functions Automated Stacking (Board Feeding) Raw Board Supply: Stacked PCB blanks are precisely fed into the production line track one by one via push plate cylinders or conveyor belts, responding to board request signals from downstream equipment (such as printers), thereby replacing manual board placement operations. Dual-mode switching: Supports stacking mode (entire stack of bare boards) and loading mode (automatic board supply from turnover boxes), enabling flexible switching between single- and double-sided mounting processes. Intelligent board retrieval (unloading) Finished board recovery: After receiving the signal indicating completion of component placement, the system automatically places the PCB boards with components into material trays, achieving end-of-line board retrieval functionality and preventing oxidation of pads caused by manual contact.
