Problems solved by technology

However, when the inspected product is carried by the manipulator, due to the fixed position of the base of the manipulator, its range of motion is limited, resulting in low efficiency in detecting the inspected product based on machine vision
However, when the detected product is carried by the conveyor belt or turntable, it is necessary to install a structure for fixing the detected product on the conveyor belt or turntable, so that the image of the side of the detected product opposite to the conveyor belt or turntable cannot be collected by the image acquisition device. thereby reducing the accuracy of the test results

Abstract

The embodiment of the invention discloses a visual inspection device which comprises a driving assembly, a guide assembly, a roller, a support and an image acquisition assembly, the guide assembly is rotationally connected with the support and comprises a guide groove penetrating through the guide assembly, and the roller is arranged below the guide groove; the roller is rotationally connected with the support and comprises a roller body and an external thread arranged on the outer surface of the roller body, the roller body is used for driving a detected product borne on the outer surface of the roller body to rotate when the roller rotates, and the external thread is used for pushing the detected product borne on the outer surface of the roller body to move along the guide groove when the roller rotates; the driving assembly is in transmission connection with the roller and used for driving the roller to rotate; and the image acquisition assembly is arranged above the guide groove and is used for acquiring an image of the detected product moving along the guide groove. According to the visual inspection device disclosed by the embodiment of the invention, whether each surface of the detected product has defects or not can be determined, and the detection accuracy is improved.

Description

technical field [0001] The present disclosure relates to the technical field of visual inspection, in particular to a visual inspection device. Background technique [0002] In recent years, with the development of production technology, the production speed of products has gradually increased. Subsequently, the quality of some products produced may not meet the requirements. In order to determine whether the quality of the product meets the requirements, the product can be inspected based on machine vision. Visual inspection refers to the use of machines instead of human eyes for measurement and judgment. Specifically, it refers to collecting the image of the inspected product through an image acquisition device and transmitting the image For a dedicated image processing system, the image processing system performs various operations based on the pixel distribution, brightness, color and other information of the image to extract the characteristics of the target, and then ...
