Problems solved by technology

The speed of manual inspection is difficult to keep up with the output speed of the punching machine. As a result, the appearance defects of thin strip products can only be inspected manually, and the probability of unqualified products being missed is very high. In addition, manual inspection is labor intensive. Larger, the subjectivity of the testers will inevitably affect the test results, and the test accuracy is not high

Abstract

The invention discloses appearance defect detection equipment for flake strip-shaped products. The appearance defect detection equipment comprises a stander, a conducting device, a warning device, a first image collecting device, a second image collecting device and terminal equipment, wherein the conducting device is used for conveying the flake strip-shaped products, the first image collecting device is used for collecting upper surface images of the flake strip-shaped product, the second image collecting device is used for collecting lower surface images of the flake strip-shaped products, and the terminal equipment is installed with an image processing program; the conducting device is mounted on the stander, and the warning device, the first image collecting device and the second image collecting device are respectively connected with the terminal equipment. The appearance defect detection equipment has the advantages that the conducting device conveys the products, the first image collecting device and the second image collecting device collect the upper surface images and the lower surface images of the flake strip-shaped products, the image processing program processes the images and outputs determination conclusions, and if the appearances of the flake strip-shaped products are not qualified, the terminal equipment controls the warning device to warn, thereby realizing the automatic detection of the flake strip-shaped products; the detection efficiency is high, the complete detection of the flake strip-shaped products can be realized, and the detection precision is relatively high.

Description

technical field [0001] The invention relates to a shape defect detection device, in particular to a shape defect detection device for a strip-shaped product. Background technique [0002] At present, thin sheet strip products (sheet strip products with a thickness of less than 2mm) have been widely used in coil stamping, electroplating, printing and engraving industries. Existing sheet-shaped strip products are mainly formed by high-speed stamping by a punching machine. The work of the punching machine is coherent. The punching machine stamps each sheet-shaped strip-shaped product sequentially and then outputs it continuously. Two adjacent sheets of sheet-shaped strip-shaped products are connected in the are sent to the follow-up station together. [0003] The detection of shape defects (including size defects, upper surface defects and lower surface defects) of existing conventional sheet strip products is usually manual detection, wherein the method of size defects is mai...
