Abstract

The invention relates to a welding machine based on visual localization. The welding machine comprises a base, a movement mechanism mounted on the base, a welding gun module connected with the movement mechanism and a visual localization module, wherein the visual localization module comprises an image acquisition module which is fixedly connected with the welding gun module and is used for acquiring image information of a workpiece to be welded, an illumination module which is matched with the image acquisition module and is used for illuminating the workpiece to be welded, a reference objectwhich has a determined coordinate value, is arranged between the workpiece to be welded and the image acquisition module and is located in a photographing range of the image acquisition module, and an image processing device which is connected with the image acquisition module and is configured to identify and acquire a characteristic pattern in an image, compare the characteristic pattern with the coordinate value of the reference object, calculate an effective coordinate value of the characteristic pattern and transmit the effective coordinate value to the movement mechanism. The inventionfurther relates to an automatic welding method by utilizing the welding machine based on the visual localization, and automatic localization and welding can be realized.

Description

technical field [0001] The invention relates to the field of automatic welding, in particular to a welding machine and an automatic welding method based on vision positioning. Background technique [0002] At present, heat exchanger welding is mostly manual welding, and the radiation and smoke generated by traditional welding are relatively harmful to workers. The existing heat exchanger welding machine adopts contact welding, that is, after the tubes are threaded, each tube needs to be welded manually, and then a positioning column with a taper is inserted into the tubes for positioning and circular welding, among which , Most of the vertical welding is argon arc welding, and most of the flat welding is second welding. This welding method has a low degree of automation and requires manual positioning, which cannot save labor or reduce the harm to the human body. [0003] The biggest difficulty in automatic welding of heat exchangers lies in positioning. Due to manual mark...
