Problems solved by technology

However, the current existing welding monitoring equipment cannot realize electric control focusing. It only determines the relative distance between the CCD and the welding torch according to the working environment on site, and then adjusts some parameters such as focal length and aperture to the best position. language, greatly increasing the difficulty of monitoring

Abstract

The invention relates to a dual-CCD (charge coupled device) welding visual monitoring system used for monitoring changes of electric arcs and weld craters during welding. The system mainly comprises a monitoring box, an LED lamp, a large CCD, a small CCD and an electric focusing lens. By adoption of the large CCD and the small CCD, an operator can clearly see a welding gun and a welding seam before and after welding through a switch; the LED lamp is mounted on a front panel of a camera, thus relative positions of the welding gun and the welding seam can be seen clearly in dark environments; by the aid of the electric focusing lens, aperture and focal length can be regulated in the welding process according to constant change of electric arc strength, so that the electric arcs and the weld craters can be seen clearly in the whole welding process, and the operator can operate conveniently; and a detection chip and a filter of particular specifications are adopted, and accordingly effect of images acquired in the welding process is enhanced.

Description

technical field [0001] The invention relates to a welding monitoring device, in particular to a welding visual monitoring system equipped with double CCDs. Background technique [0002] In the contemporary stage, with the continuous progress and development of welding technology, the use of automatic control means to monitor welding quality has become an important direction of welding technology development. Under the premise of continuous development and application of welding automation, how to ensure Welding quality has become a focus of people's concern. Around the central issue of welding quality, welding workers at home and abroad have invested considerable manpower and material resources in a large number of research work. In arc height control, weld automatic tracking control, welding penetration control However, these methods only transmit relevant data to the processor through voltage and current sensors. The operator can only analyze the arc and molten pool indire...
