Technical Field
[0001] This utility model relates to the technical field of workpiece appearance full inspection equipment, specifically a workpiece appearance full inspection equipment. Background Technology
[0002] In today's booming manufacturing era, the production scale of various workpieces is increasing daily. Their appearance quality plays a crucial and undeniable role in the overall quality of products, market competitiveness, and user experience. Whether it's precision electronic components, automotive parts, or packaging containers for everyday consumer goods, appearance defects such as scratches, dents, dimensional deviations, and surface contamination can affect the product's functionality, aesthetics, and reliability, leading to serious consequences such as customer complaints and product recalls, causing significant economic losses and reputational damage to enterprises.
[0003] Traditional workpiece appearance inspection methods mainly rely on manual visual inspection, which has many drawbacks. On the one hand, manual inspection is inefficient and cannot meet the pace of large-scale production, especially when a large number of workpieces need to be processed quickly on the production line, where manual inspection often becomes a bottleneck in the production process. On the other hand, the accuracy of manual inspection is difficult to guarantee. Due to factors such as visual fatigue, subjective judgment differences, and limited ability to identify minor defects, missed or false inspections are prone to occur, leading to defective products entering the market.
[0004] Against this industry backdrop, comprehensive workpiece appearance inspection equipment has emerged. Leveraging advanced optical imaging technology, image processing algorithms, and automated control technology, it enables rapid, comprehensive, and accurate inspection of workpiece appearance. By capturing image information of the workpiece surface through a high-resolution camera and then processing and analyzing the images using sophisticated image analysis software, the equipment can automatically identify various appearance defects and accurately locate their positions. Simultaneously, it provides real-time feedback of the inspection results to operators or the production control system. This not only significantly improves inspection efficiency, matching the speed of modern production lines and ensuring smooth production processes, but also significantly enhances inspection accuracy, reduces various risks caused by appearance quality issues, provides strong technical support for enterprise product quality control, helps the manufacturing industry improve product quality levels in fierce market competition, establishes a good brand image, and promotes high-quality development of the entire industry.
[0005] Currently, most workpiece appearance inspection equipment uses glass turntables to transport workpieces, allowing them to pass through various inspection devices sequentially for screening. However, over time, dust accumulates on the surface of these turntables, which can create shadows or spots in the inspection images that appear as defects. For example, when inspecting smooth metal workpieces, dust on the turntable can produce dark spots in the image under light. These dark spots might be mistaken by the inspection system as scratches, dents, or other defects, leading to misjudgments, increasing the product rejection rate, and causing otherwise qualified workpieces to be incorrectly selected for rework or scrap. Currently, glass turntables are mostly cleaned manually periodically, which is time-consuming, labor-intensive, increases the workload of staff, and reduces the efficiency of the workpiece appearance inspection equipment.
