The main function of automated visual inspection is to achieve rapid and accurate quality inspection and monitoring of products, thereby helping manufacturers improve the efficiency of the production process and reduce the risk of product quality defects. What are the main scenarios in which visual inspection technology is used in the production and manufacturing field?
Appearance inspection of products
The appearance inspection of products is one of the most widely used scenarios in visual inspection technology. With the improvement of consumption level, the appearance quality of products plays a crucial role in consumers' purchasing decisions. The traditional manual inspection method relies on the judgment of the human eye, which is prone to problems such as fatigue and subjective judgment. Visual inspection technology can accurately analyze and measure the details, colors, and defects on the product surface through algorithms and models, ensuring the consistency and stability of product quality.
At present, the application of visual inspection technology in industrial product production has become relatively mature. In industrial product production, such as automotive components, electronic circuit boards, glass substrates, etc., the application of visual inspection technology focuses on detecting the integrity of the target product, accuracy of size and position, and compliance with visual appearance. The overall inspection technology is not difficult to handle.
For the production of large-scale products such as household appliances and sheet products, the application of appearance detection technology is more refined, with more detection information and a large detection area. In addition to the elimination of visual appearance defects and assembly defects of the target product, it also includes the detection of consistency between printed products, trademarks, and product model numbers. This puts forward higher precision and flexibility requirements for visual detection technology.
Specifically, the application of appearance inspection technology mainly includes the following three sub scenarios:
Fine inspection of appearance
Scratches, bumps, dirt, scratches, paint peeling, color differences, etc. on the overall appearance of the target product; Edge chipping, insect holes, scratches, hole defects, etc. of board products; Scratches, dirt, shortage of materials, etc. on the injection molded parts of the product;
Intelligent error and leak detection
Consistency and accuracy testing of surface energy efficiency labels, logos, nameplates, machine woven labels, and other printed labels for the target product; Consistency testing of product components, such as panels, buttons, door bodies, water dispensers, screws, etc;
Assembly defect detection
Detection of the relative position of the components of the target product, such as between doors and buttons; Product flash seam, unevenness, and front and rear unevenness size inspection.
Product size measurement
Visual inspection technology has also played a huge role in product size and shape detection. During the manufacturing process, the size and shape of the product must meet predetermined requirements to ensure its functionality and correct assembly. In traditional manufacturing processes, manual measurement of the size and shape of products is often time-consuming and prone to errors. Visual inspection technology can achieve automatic detection of various key dimensional parameters of products and components, such as gaps, breaks, angles, length and width, area, curvature, thickness, holes, holes, and relative positions of structural components, through high-precision image processing algorithms, and compare them with design requirements, This greatly improves the accuracy and efficiency of measurement by determining whether the product meets the standards.
Intelligent error prevention detection
Faced with continuously changing market demand, manufacturers have to accelerate their transformation and upgrading to meet diverse needs and achieve stable output with quality and quantity. However, the current artificial visual inspection and simple visual measurement methods used by manufacturing enterprises are limited by manual labor and energy, and cannot be observed and tested for a long time, making it impossible to meet the increasingly high requirements for product quality testing.
Automated visual detection technology is mainly used for the following three types of segmented scenes:
Consistency testing of energy efficiency labels, nameplates, machine labels, box labels, warning labels, operation guidelines, promotional posters, warranty labels, etc. with product models;
Consistency detection between logos and product models, autonomously switching between nearly a hundred logo models;
Consistency inspection of components such as handles, display screens, screws, operation panels, buttons, door bodies, water dispensers, footings, power cords, hinge covers, packaging boxes, etc. with product models and installation positions.
The application of automated visual inspection technology in the manufacturing industry provides manufacturers with powerful tools, which can not only achieve rapid and accurate detection of product quality, improve product quality and production efficiency, but also reduce production costs. With the continuous development of technology, it is believed that the application of visual inspection technology in the manufacturing industry will become increasingly widespread, providing manufacturers with more opportunities and competitive advantages.
