Description

technical field [0001] The invention relates to a broken needle detection circuit for a PCB drilling machine and a detection method thereof, and belongs to the innovative technology of a broken needle detection circuit and a detection method thereof for a PCB drilling machine. Background technique [0002] When the PCB drilling machine processes micro-holes on the PCB board, the phenomenon of broken needles often occurs. In the process of high-speed processing, it is necessary to detect the occurrence of broken needles in a timely and accurate manner, so as to improve the yield of PCB boards. The traditional vacuum-type broken needle detection method has the defects of untimely judgment and high misjudgment rate, while laser-type broken needle detection has the problem of high misjudgment rate. Contents of the invention [0003] The object of the present invention is to provide a broken needle detection circuit for PCB drilling machines with high judgment accuracy and tim...
