Visual inspection system and method for glued products

Abstract

The invention discloses a visual inspection system for glued products. The system comprises a conveyer belt, a sensor, a PLC (Programmable Logic Controller), a photographic device, light sources, an industrial robot, a removal device and an industrial personal computer, wherein the industrial personal computer is arranged on a rack, and the photographic device, the light sources and the industrial robot are connected with the industrial personal computer; the photographic device comprises a top camera and a detection camera; the light sources comprise a detection light source and a backlight source; the backlight source is arranged at the bottom of the conveyer belt; the detection camera and the detection light source are arranged on the industrial robot above the conveyer belt; glued products with glue containing fluorescent agent are arranged on the conveyer belt; the industrial robot rotates to drive the detection light source and the detection camera to detect the products; the qualified products passing detection are conveyed by the conveyor belt, and the unqualified products are removed by the removal device. The invention further discloses an inspection method for the visual inspection system for glued products. The system disclosed by the invention is simple in structure and method, the operation is convenient and rapid, the glued products can be comprehensively and reliably detected, and the detection efficiency is high.

Description

technical field [0001] The invention relates to a visual detection system and detection method for glued products. Background technique [0002] At present, in the field of industrial production, gluing, as an advanced product bonding method, has been more and more widely used. The quality of gluing determines the final quality of the product, so testing the quality of gluing is an important task. The key inspection process, and the most difficult to detect the facade, such as the bonding between the parts of the electronic product with the facade, the bonding of the outsole and the upper of the shoe industry, etc. Since many glues are transparent, colorless or light-colored, it is necessary to add a fluorescent agent to the glue during detection, and use a UV light source to develop the color. The original production process uses manual visual inspection of the glued area, because the product has a facade and cannot be viewed at a glance. Workers need to pick up the produc...

Problems solved by technology

The original production process uses manual visual inspection of the glued area, because the product has a facade and cannot be viewed at a glance. Workers need to pick up the product, place it under a UV light source, and rotate the product 360 to view it point by point. There are three major disadvantages: 1) Subjective misjudgment is prone to occur 2) The efficiency is very low 3) UV light source is harmful to human health
