AI Technical Summary

Technical Problem

Existing visual inspection technologies require multiple vision cameras when inspecting the sides of products, resulting in high equipment costs and large size. Furthermore, lens distortion leads to poor edge imaging, making it difficult to achieve high-precision inspection.

Method used

An inclined reflector is used to fold and project the image of the product's side onto the central area of ​​the vision camera. Combined with a ring light source and a light-transmitting plate, this ensures that light enters the central area of ​​the vision camera clearly for imaging. Through the coordinated movement of a sliding mechanism and an obstacle avoidance device, high-precision detection of the product's side is achieved.

Benefits of technology

Achieve high-precision inspection of all sides of a product under single-vision camera conditions, reduce equipment cost and size, improve imaging quality and uniformity, and avoid the influence of light source obstruction.

Abstract

The invention relates to a product side face high-precision visual detection system and a detection method thereof, and relates to the technical field of visual detection.The product side face high-precision visual detection system comprises a workbench, a light source, a visual camera and a reflective mirror, the workbench is provided with a detection area where a product is placed, and the light source is used for illuminating the side face of the product in the detection area; the visual camera is arranged above the detection area, the multiple reflectors are obliquely arranged on the workbench and correspond to the side faces of a product in the detection area in a one-to-one mode, the reflectors are located on the sides of the corresponding side faces of the product, and the reflectors are used for reflecting the side faces of the product after the light source illuminates the side faces of the product. Light reflected by the side surface of the product is reflected to the middle area of the visual camera through the reflector. According to the invention, high-precision detection of each side surface of the product is realized under the condition of the monovision camera, and the equipment cost and the size are reduced.
