Problems solved by technology

[0004] The first of these three methods is too labor-intensive, and false detection may occur, and the quality cannot be guaranteed
The second method is more convenient than the first one, and reduces the fatigue intensity of the inspectors, but fundamentally, manual inspection is still the main method, and it is difficult to achieve standardization
The third detection method needs to work under dark room conditions
Moreover, the detection system is complicated, the investment is large, and the operation technology requires proficiency

Abstract

The invention relates to a piston detection platform and method based on image acquisition, comprising an image acquisition device and a computer. The image acquisition device includes a worktable, the upper surface of the worktable is provided with a rotation mechanism, the rotation mechanism can clamp the piston, and the rotation mechanism can drive the piston to rotate along its own vertical axis. The upper part of the worktable is provided with a plurality of image acquisition mechanisms, the plurality of image acquisition mechanisms are arranged around the rotating mechanism, and the plurality of image acquisition mechanisms can respectively take pictures of the piston at different angles to collect images of the piston at different angles. The agency passes the photo to the computer. The computer can perform image recognition on the photo to judge whether the parameters of the piston meet the requirements. The invention can realize the automatic detection of the quality of the piston, reduce the error of manual detection by the naked eye, and reduce the labor intensity of the detection personnel.

Description

technical field [0001] The invention belongs to the technical field of piston detection, and in particular relates to a piston detection platform and method based on image acquisition. Background technique [0002] With the rapid development of product parts production, assembly technology and system automation, social development has put forward higher and higher requirements for quality and shape error detection and precise process control of various products. [0003] The inventor has learned that there are three fundamental measures adopted for piston quality inspection at home and abroad: one is manual visual inspection, and the human eye is directly used to pry into it to make a rough judgment; On the screen, it is still judged by human eye observation; the third is laser detection, by emitting laser light to the surface of the detection piece, and then receiving feedback information through the electronic receiving element to form the surface shape and its details. ...
