Device for detecting welding track of corrugated plate of container based on laser ranging

Abstract

The invention relates to a device for detecting the welding track of a corrugated plate of a container based on laser ranging, which comprises a laser displacement sensor and a welding gun position and posture adjusting device; one end of the welding gun spatial position and posture adjusting mechanism is fixed on a stand; the laser displacement sensor is arranged at the lower end of the welding gun spatial position and posture adjusting mechanism; and the laser displacement sensor and the welding gun position and posture adjusting device are connected with a circuit control device through circuits. Through the detection of a weld joint of the corrugated plate, the control of the position and the posture of the welding gun and the autocontrol of a welding process, the device achieves the effect of thickness consistency among downhill welding sections between wave peak and wave trough of the corrugated plate, an uphill welding section between the wave trough and the wave peak and a linear section of the wave peak and a linear section of the wave trough, remarkably improves the welding evenness of each welding section, greatly reduces the labor intensity of laborers, has rapid and convenient parameter adjustment and reduces the labor cost of production. The welding speed is more than three times of that of common manual welding or contour welding; and the whole process is automatically controlled.

Description

technical field [0001] The invention relates to a detection device for a welding track of a container corrugated plate, in particular to a detection device for a welding track of a container corrugated plate based on laser ranging. Background technique [0002] At present, my country is the world's largest producer of containers, and container manufacturing is a labor-intensive and material-intensive industry. At present, the production process of my country's containers, especially the welding of corrugated plates, is mainly based on manual welding and mechanical profiling semi-automatic welding. The working environment of workers is poor, the labor intensity is high, and the welding quality is difficult to control. At the same time, due to the inability to effectively track and adjust the welding specifications during the welding process, the quality of the welds formed by different slope sections is significantly different, and it is difficult to meet the welding quality c...

Problems solved by technology

The contact sensor converts the change of the welding seam into the position change of the guide rod or the guide wheel, and converts it into an electrical signal. Due to its stable performance and low cost, this sensor has been widely used in production. Due to the limitation of tracking accuracy and speed, it has been It is not suitable for high-precision and high-speed welding fields; the arc sensor uses the parameters of the arc itself as the tracking target, and can respond to changes in the weld seam in real time, but the detection accuracy is easily affected by the droplet transfer form and spatter during the welding process, especially for thin plates In the welding of butt joints and lap joints, the application method is difficult to master
