Online visual inspection assembly for finished plastic products

Abstract

The invention discloses an online visual inspection assembly for finished plastic products. The online visual inspection assembly comprises a base, wherein a working table is fixedly mounted on the base, a feeding groove is fixedly connected to the working table, a leveling groove and a rubbing through groove are formed in the working table, and a pressing structure is mounted on the working table; a rubbing structure with a working face switching function is mounted at the bottom of the working table, a hanging column is fixedly mounted on the working table, a direct shooting camera is fixedly mounted on the hanging column, a mounting seat is fixedly mounted on the working table, a rubbing camera is fixedly mounted on the mounting seat, and the rubbing structure is connected with a rubbing recovery structure. According to the online visual inspection assembly, the plastic tube can be directly shot through the direct shooting camera mounted on the device, a preliminary detection picture is obtained, and the rubbing structure is matched with the rubbing camera, so an image at the rubbing part of the plastic tube can be shot, an effective supplement effect is achieved, and the defect discovery rate of the plastic tube is improved.

Description

technical field [0001] The invention relates to the technical field of photogrammetry, in particular to an online visual inspection component for finished plastic products. Background technique [0002] Photogrammetry is a technology that uses an optical camera to obtain images and processes them to obtain the shape, size, position, characteristics and their relationship of the object being photographed. At present, photogrammetry technology has been widely used in the field of industrial production and has become a product vision main means of detection. [0003] Plastic products refer to various products prepared with plastic as the main material, among which plastic tubes are very important plastic products. In the production process of plastic pipes, due to various reasons such as raw materials, processing technology, human negligence, etc., there may be problems with the size of the finished plastic pipes or defects on the surface. These problems will affect the qualit...

AI Technical Summary

Problems solved by technology

However, most of the photogrammetric visual inspection structures currently used are direct-shooting, and the plastic tubes are directly photographed.

However, it is limited to the pixels of the photographic equipment and other issues, resulting in low detection accuracy, and it is difficult to identify shallow defects on the surface of plastic pipes
