Visual inspection machine for laser welding part

Abstract

The invention provides a visual inspection machine for a laser welding part, which is used for quickly detecting a finished welding part through CCD visual inspection and a torque sensing thread detection technology, so that the labor intensity of workers is reduced, and the detection efficiency is improved. The visual inspection machine comprises: a single-axis robot provided with a single-axis track; a conveying carrier which comprises a bottom transmission end and an upper workpiece fixing part; a CCD detection mechanism which comprises a bottom light source surface, a first camera and a second camera; a thread detection mechanism which comprises a gantry bracket, a thread detection head, a sliding table cylinder and a torsion motor; wherein the output end of the single-axis robot is fixedly connected with the bottom transmission end, the upper workpiece fixing part is used for fixedly arranging a to-be-detected welding part, and the single-axis track of the single-axis robot has a part placing station, a CCD detection station, a thread detection station and a part taking station in the length direction; and the single-axis track is horizontally arranged, and a CCD detection mechanism is arranged at the position, corresponding to the CCD detection station, of the single-axis track.

Description

technical field [0001] The invention relates to the technical field of product inspection, in particular to a laser welding piece visual inspection machine. Background technique [0002] The existing finished weldment needs to be inspected for the integrity of the shape components and the weld bead. The existing inspection requires at least two workers to manually inspect, and at the position of the upper threaded hole of the finished weldment, it is necessary to manually check the screw-in of the tooth gauge through the hand-held standard. Unscrew to judge whether the thread meets the quality requirements. Since the existing inspections are all performed manually, the manual labor intensity is high and the efficiency is low. Contents of the invention [0003] In view of the above problems, the present invention provides a laser weldment visual inspection machine, which quickly detects finished weldments through CCD visual inspection and torque sensing thread detection tec...
