Monocular self-adaption cross laser visual corrugated plate welding line tracking sensor

Abstract

The invention relates to a monocular self-adaption cross laser visual corrugated plate welding line tracking sensor. The sensor comprises a set of self-adaption visual viewing field device, a camera based on an area array CCD, a self-adaption oscillator, a linear laser emitter, a spot laser emitter, a set of self-adaption ahead distance transfer mechanism and a sensor protective cover. In a welding starting point position, the self-adaption oscillator can perform self-adaption swing to adjust the length of scanning laser, and the self-adaption visual viewing field device can adjust a visual viewing field range in a self-adaption manner; in the welding process, a height deviation of a welding gun is obtained according to a distance from the intersection between linear laser and a welding line and the intersection between the linear laser and the scanning laser, a left-right deviation is obtained through the length change of the scanning laser, and the turning point position and the bending angle of the corrugated plate welding line are determined according to the bending position and angle of the scanning laser; and the self-adaption ahead distance transfer mechanism can adjust an ahead distance according to the parameter change of a welding process in a self-adaption manner.

Description

technical field [0001] The invention relates to the field of seam tracking, and is a monocular self-adaptive cross laser vision corrugated plate seam tracking sensor. Background technique [0002] Due to the good mechanical properties of corrugated plates, they are currently widely used in the production of containers. The production of containers is a labor-intensive industry that requires a large number of welders, and the working environment is harsh and labor costs are high. Therefore, it is urgent to realize the automation of corrugated plate welding. The problem. The current welding methods for corrugated plates are mainly manual welding and mechanical profiling semi-automatic welding. The welding efficiency is low and the welding quality is difficult to guarantee, and the quality of the weld seam formation of corrugated plates is not high. These problems have existed for a long time and have not been solved in the welding of corrugated plates in my country, so that t...
