Description

Technical Field

[0001] The present invention relates to the technical field of visual detection, and more specifically, the present invention relates to a visual detection device. Background Art

[0002] Visual detection is to use a machine to replace the human eye for measurement and judgment. It detects, identifies, and classifies objects in an image by using image processing and computer vision algorithms. Specifically, visual detection converts the captured target into an image signal through a machine vision product (such as an industrial camera, which is divided into two types: CMOS and CCD), and transmits it to a dedicated image processing system. This system converts these image signals into digital signals according to information such as pixel distribution, brightness, and color, and performs various operations to extract the features of the target. Finally, the system controls the actions of on-site equipment according to the discrimination results.

[0003] Although the visual detection devices in the prior art can be used normally, there are still many disadvantages in actual use. For example, the visual detection devices in the prior art can only detect defective products and cannot remind the staff which surface of the product has defects, resulting in a low reprocessing efficiency of defective products. It is impossible to repair and reprocess defective products targeted, so that defective products are processed into standard products, which makes the actual use effect of the visual detection devices in the prior art poor.

[0028] The specific implementation method is as follows: When using the present invention, open the transparent plastic cover 3 at the top together with the perspective glass 2 thereon, then place the product into the metal outer frame 1 at the established position, so that the product falls on the perspective glass 2 at the bottom. Then, the partition visual inspection cameras 14 on the six faces all start to take pictures and work. Then, the six partition image recognition modules 13 respectively detect the images of their respective partitions. If the detection is correct, the partition alarm flash lamp 12 does not start. If a problem is detected in the product image on a certain face, the partition alarm flash lamp 12 is automatically started to remind the staff that there is a defect on this face of the product, which is convenient for the staff to record, so as to facilitate the subsequent reprocessing and repair of defective products. It can also send the detection results to the mobile phone terminal 17 for remote recording, making this device convenient for remote use. This makes the present invention not only able to detect defective products, but also able to point out which face of the product has defects, which is convenient for the staff to record, so as to facilitate the subsequent repair and reprocessing of defective products, and the actual use effect of the present invention is better.
