Abstract:
1. A printed circuit board (PCB) delivery apparatus, to deliver a plurality of PCBs to a PCB transmission guideway, the PCB delivery apparatus comprising: two gear groups, located on two opposite sides of the PCB transmission guideway, each of the two gear groups comprising a master gear; a pair of transmission belts, geared onto and driven by the two gear groups, wherein the pair of transmission belts are respectively perpendicular to the PCB transmission guideway and define a PCB accommodation space therebetween suitable to receive the plurality of PCBs, and wherein each transmission belt comprises a plurality of projections, located on an outer surface of the transmission belt, and the projections of the pair of the transmission belts are horizontal and correspondingly opposite to support the PCBs thereon; and a driver, to rotate the two master gears of the two gear groups synchronously and inversely; wherein when the projections supporting one of the plurality of PCBs approach the PCB transmission guideway, the projections move away from each other, such that the PCB supported thereon drops onto the PCB transmission guideway.
