Description

Technical Field

[0001] The present application relates to the field of visual inspection technology, and in particular to a high-precision appearance visual inspection device. Background Art

[0002] In industrial production, product appearance quality inspection is crucial. With the continuous development of the manufacturing industry, the requirements for precision and comprehensiveness in product appearance inspection are becoming increasingly stringent. The accuracy of appearance inspection is directly related to product quality and performance, and thus to a company's production efficiency and market competitiveness. Accurate appearance inspection can promptly identify product defects and problems, ensuring that products meet relevant standards and customer requirements.

[0003] In the existing technology, manual inspection and traditional mechanical inspection equipment are often used. Manual inspection mainly relies on the naked eye observation of the inspectors. The inspectors will check the products one by one on the product production line and judge whether there are any defects in the appearance of the products by vision. Traditional mechanical inspection equipment uses mechanical probes, calipers and other tools to measure the key dimensions of the products.

[0004] Regarding the aforementioned technologies, manual inspection has significant limitations. Inspectors are easily affected by factors such as fatigue and lack of concentration, resulting in poor accuracy and stability of test results, as well as low inspection efficiency, making it difficult to meet the needs of large-scale production. Traditional mechanical inspection equipment can only detect specific dimensional parameters, making it difficult to comprehensively and accurately detect complex appearance features and surface defects. Furthermore, the inspection process is relatively cumbersome, requiring manual operation and adjustment of inspection tools, which is inefficient and leads to low product appearance inspection efficiency.
