The invention discloses an accurate positioning mechanism applicable to vision measurement of a pulling rivet. An extension type suction cup positioning mechanism of the accurate positioning mechanism is fixedly arranged on a two-way controllable magnetic slide rail mechanism. A positioning block of the extension type suction cup positioning mechanism is connected with a suction cup electromagnet; the pulling rivet is positioned between a lower sliding plate and an upper sliding plate; a flat plate of the two-way controllable magnetic slide rail mechanism is connected with a first electromagnet core; the first electromagnet core is connected with a second electromagnet core; the second electromagnet core is fixedly arranged on a second slide block; a first electromagnet and a second electromagnet are fixedly arranged on an iron plate; a first slide block and the second slide block are arranged on a slide rail; and the slide rail is fixedly arranged on a base. By combining the extension type suction cup positioning mechanism with the two-way controllable magnetic slide rail, the pulling rivet can be vertically and accurately positioned at a specific position so as to improve the accuracy of detection in the vision measurement, realize automation of the detection, improve the production efficiency and reduce the labor intensity.
Description
technical field [0001] The invention belongs to the field of automation equipment, in particular to an accurate positioning mechanism suitable for visual measurement of blind rivets. Background technique [0002] At present, with the continuous improvement of industrial automation, the automatic detection technology of industrial products is becoming more and more important. The geometric parameters of screws must be detected in real time during production to ensure their quality. In particular, mechanical parts such as rivets have stricter requirements. Traditional manual measurement is difficult to meet real-time, accurate and stable online detection. Research on precision measurement using machine vision is extensive and has been applied in many fields. But the online dimensional visual inspection directly connected with the production line is almost blank. Contents of the invention [0003] The purpose of the present invention is to use a precise positioning mechan...
