Description

Technical Field

[0001] The utility model relates to the technical field of screening, in particular to a machine vision detection and screening robot. Background Art

[0002] The machine vision inspection and screening robot is an automated inspection system based on machine vision technology. It combines the robot's operating capabilities with the perception and analysis functions of machine vision to achieve efficient screening and inspection tasks. During the screening process, the robot can obtain the image information of the object, and after denoising, enhancement and correction by image processing technology, it can extract the key features in the image. Then, the target object is classified and judged through algorithms to achieve accurate screening.

[0003] After searching, a Chinese patent with publication number CN213194539U discloses an automatic screening robot for brick-making raw materials. The screening device for brick-making raw materials can effectively discharge impurities, but lacks automated equipment and requires the assistance of multiple employees. The utility model designs an automatic screening robot for brick-making raw materials to solve the problems of impurity filtering and screening of raw materials and low degree of automation. Therefore, the sensor senses the falling of the material and sends a signal to the controller. The controller controls the shaking screen, the shaking screen cylinder and the pulley to work, thereby realizing the effect of automated operation of the screening device.

[0004] The above-mentioned screening robot still has some shortcomings when screening. When screening materials, the size of the mesh in the screen plate is not easy to adjust, so it is not easy to adjust according to the size of the material to be screened, which reduces the flexibility of the screening robot when screening. If the mesh is too large, it is easy to cause the screened material to be mixed with too many impurities, which is not easy to meet the particle size requirements, reduces the adjustability, and thus reduces the uneven particle size distribution after screening, resulting in reduced screening effect.
