[0036] When in use;

[0037] Before PCB loading, the flow channel in-place sensing photoelectric 310 senses that there is no material in the material bin. At this time, the lifting screw 308 drives the non-return mechanism 304 to descend to the bottom of the belt line of the docking flow channel 302. The PCB is placed in the Tray plate for material, and the whole stack of Tray plates is placed on the docking flow channel 302.
