What items can the appearance inspection detect on products?

The Appearance Defect Detection System is primarily used for quickly identifying surface defects in samples, such as dents, cracks, warping, gaps, stains, sand particles, burrs, bubbles, and uneven colors. The samples that can be inspected range from transparent to opaque. Next, we will delve into what appearance defect detection entails.

Historically, product appearance inspections were typically conducted visually, which could lead to inconsistencies in measurement standards due to human factors and potential misjudgments from visual fatigue over extended periods. With the deep integration of computer technology and the advanced cooperation of optical, mechanical, and electrical technologies, rapid and accurate inspections are now possible.

If the surface of a product exhibits significant differences in physical or chemical properties compared to other areas, it can greatly affect the product's appearance and functionality. This includes scratches, spots, or holes on metal surfaces, color variations or creases on paper, and impurities, cracks, or stains on non-metallic surfaces like glass. Surface defects not only impact the aesthetic and comfort of the product but also its performance. Therefore, manufacturers place great importance on surface defect detection to identify them promptly, effectively controlling product quality. Additionally, analyzing the results can reveal issues in the production process, helping to eliminate or reduce defects, and prevent potential trade disputes, thereby upholding the company's reputation.

Optical inspection technology utilizes a light source system, image acquisition system, image processing system, mechanical action system, and data statistical management system to illuminate the products under inspection, highlighting surface defects for camera photography. Commonly used light sources include halogen lamps, fluorescent lamps, and light-emitting diodes (LEDs). LEDs have gained widespread application due to their small size, low power consumption, fast response time, excellent monochromaticity, high reliability, even and stable light output, and ease of integration.
