Example Embodiment
[0022] The present invention provides a detection device independent of the component mounting machine at the upstream of the component mounting machine (such as the Flip Chip Mounter), which is used to quickly and independently detect the circuit The bad mark or / and local fiducial mark on the multiple sub-boards on the board are passed to the downstream pick-and-place machine, so that the subsequent placement steps can be based on the mark detection device The obtained detection data is placed on the sub-boards belonging to the good product, which greatly reduces the standby time of the picking and placing machine (including the time of loading, unloading, target detection and detection time of defective product marks). There is no need to perform the inspection work on the placement machine, thereby increasing the production capacity of the overall production line. In addition, the detection device of the present invention can achieve a relatively high-precision correction op...
