Laser vision positioning sensor for automatic riveting of automobile body

Abstract

The invention provides a laser vision positioning sensor for automatic riveting of an automobile body. The laser vision positioning sensor is fixed on a riveter at the tail end of a robot and comprises an intelligent camera module, a double-line vertical laser light source and an external trigger controller; the double-line vertical laser light source emits two laser lines which are vertical to each other; and the external trigger controller is connected with the intelligent camera module and the double-line vertical laser light source, and sends signals to the intelligent camera module and the double-line vertical laser light source by using monopulse. According to the laser vision positioning sensor for automatic riveting of the automobile body, the double-line laser transmitter is adopted as line structural light, so that the effect of multiple times of photographing of single laser can be achieved through single-time photographing; the external trigger controller is additionally arranged, the requirement for dynamic photographing is met. The laser vision positioning sensor can be applied to an automobile body-in-white production line, and meet the requirement for high takt.

Description

technical field [0001] The invention relates to the technical field of three-dimensional sensors for riveting positioning of aluminum automobile bodies, in particular to a laser vision positioning sensor for automatic riveting of car bodies. Background technique [0002] With the development of the automobile industry, the lightweight body-in-white has become the development direction of passenger cars, and new materials and technologies are continuously applied to the manufacture of body-in-white. The weight of aluminum alloy is about one-third of that of steel, so it has become one of the preferred new materials for body-in-white. The application of new materials has led to the development of new connection technologies, and riveting dedicated to automotive aluminum body-in-white has become an extremely popular and commonly used new connection method. [0003] Correspondingly, in the current riveting of aluminum body-in-white, there are extremely high requirements for the...
