Abstract

The invention discloses a line laser sensor automatic calibration device for weld seam tracking. The line laser sensor automatic calibration device comprises a first manual turntable, a second manual turntable, a cross sliding table mechanism and a loading platform; the fixed end of the first manual turntable is connected with a first right-angled connection plate; the rotary end of the first manual turntable is connected with the fixed end of the second manual turntable through a second right-angled connection plate; the rotary end of the second manual turntable is connected with a third right-angled connection plate; the cross sliding table mechanism is arranged on the third right-angled connection plate; the loading platform is arranged on the cross sliding table mechanism; and a dot matrix calibration plate and a light source are arranged on the loading platform. The invention also discloses a line laser sensor automatic calibration method for weld seam tracking. With the four-degree-of freedom line laser sensor calibration device of the invention adopted, operational simplicity in image acquisition in a calibration process and the accuracy of calibration can be improved, and the measurement accuracy of the line laser sensor ranges from -0.02mm to +0.02mm, and accurate pose relations can be provided for subsequent weld seam tracking measurement.

Description

technical field [0001] The invention belongs to the technical field of welding. In particular, it relates to a line laser sensor automatic calibration device and method for seam tracking. Background technique [0002] Welding is an essential production process in industrial production. In daily production and life, welding products can be seen everywhere, ranging from aerospace to simple iron doors, all of which have the application of welding technology. Manual welding is still the main force of the current welding process, but it takes a lot of cost and time to train an excellent welder, and the environment of welding work is often high-risk and polluting. Therefore, welding robots will be an important direction of industrial development. [0003] Faced with a variety of welding environments, there are all kinds of welds. The traditional teaching and reproduction type cannot meet the complex welding environment. Automatic welding seam tracking technology will make up ...
