Workpiece reference surface positioning detection device and method

Abstract

The invention discloses a workpiece reference surface positioning detection device and method. A to-be-detected target workpiece in the device is placed on a workpiece transporting and conveying module, a workpiece fixing clamp is arranged on one side close to the tail end of the transporting and conveying module, an image acquisition and detection module is arranged on the other side close to the tail end of the transporting and conveying module, and the workpiece fixing clamp is electrically connected with the workpiece transporting and conveying module and the image acquisition and detection module. When a proximity sensor detects the target workpiece, the workpiece transporting and conveying module stops, and meanwhile, the workpiece fixing clamp fixes the target workpiece to be detected; an industrial camera and a laser displacement sensor of the image acquisition and detection module acquire key points of a reference surface of a target workpiece, so that related information of the reference surface is obtained, and reference surface positioning detection of the workpiece is realized. The reference surface of the workpiece is positioned and detected in a non-contact manner, automatic detection of the reference surface is realized, and the detection precision and efficiency are improved.
