Problems solved by technology

[0002] After the product packaging is completed, it is necessary to inspect the appearance of the packaging to detect whether there are defects such as missing codes, missing prints, and wrong edges. The existing inspection method is to transport the product through the conveyor belt after the packaging is completed. The detection camera takes pictures and detects, and judges whether the packaging has missing codes, missing prints, wrong edges, etc. according to image processing and comparison. Not fixed, and will enter the detection area at different angles, resulting in the detection camera not being able to accurately detect each product package, prone to missed product inspections, and increasing the defective rate of product packaging

Abstract

The invention discloses packaging product defect detection equipment based on machine vision, and the equipment comprises a rack and a controller, wherein the rack is provided with a conveying belt, two sides of the conveying belt are provided with lifting rods, the tops of the lifting rods are provided with camera supports, and the camera supports are movably provided with detection cameras; a gear motor used for adjusting the shooting angle is installed on each detection camera, induction gratings are symmetrically installed on the two sides of one end of the conveying belt, screw translation shooting or rotating disc rotating shooting can be adopted, the shooting angles of the detection cameras can be adjusted through the gear motors, and therefore the shooting angles of the detection cameras are more flexible; product packages located at different positions and in different angle orientations can be detected, whether defects exist in the outer packages of the products or not can bejudged more accurately, and therefore the reject ratio of the product packages is reduced.

Description

technical field [0001] The invention relates to a detection device, in particular to a packaging product defect detection device based on machine vision. Background technique [0002] After the product packaging is completed, it is necessary to inspect the appearance of the packaging to detect whether there are defects such as missing codes, missing prints, and wrong edges. The existing inspection method is to transport the product through the conveyor belt after the packaging is completed. The detection camera takes pictures and detects, and judges whether the packaging has missing codes, missing prints, wrong edges, etc. according to image processing and comparison. It is not fixed, and will enter the detection area at different angles, resulting in the detection camera not being able to accurately detect each product package, prone to missed product inspections, and increasing the defective rate of product packaging. Contents of the invention [0003] In order to overc...
