Abstract

This utility model discloses a printing plate punching machine with printing plate quality inspection capabilities. It includes a printing plate punching machine body, an auxiliary lens device at the near-object end of the camera of the printing plate punching machine body, and an image detection device electrically connected to the camera output end of the printing plate punching machine body. The auxiliary lens device and the image detection device are electrically connected to a printing plate inspection and control system, which is electrically connected to the control system of the printing plate punching machine body. This invention, by integrating an automatically switching auxiliary lens device and a high-efficiency image detection system, enables existing punching machines to perform precise segmented photography and defect detection on the printing plate. This allows for the rapid and accurate identification of defects that may cause quality problems and material waste, improving the inspection quality and speed of the printing plate, ensuring high-standard and high-quality output of printed materials, while also increasing the functional versatility of existing punching machines and improving equipment utilization.
