Abstract

The invention relates to a linear array CCD based automatic welding seam tracking device and method, which solve the technical problems that an existing video detecting processing based welding steamtracking technology is lagged, is low in aligning accuracy, is relatively great in positioning errors, and cannot quickly rectify a deviated machine head. The linear array CCD based automatic weldingseam tracking device comprises an array CCD module, a main controller, a servo driver, a linkage mechanism, a travelling mechanism, a welding flux box and a machine head, wherein the linkage mechanismcomprises a rack, a workbench, a machine head mounting frame, a lead screw pair and a servo motor; the servo motor is connected with the rack; the lead screw pair is connected with the output shaft of the servo motor; the inner side surface of the workbench is connected with a nut on the lead screw pair; the machine head mounting frame is connected with the outer side surface of the workbench; the rack is fixedly connected on the travelling mechanism; the machine head is connected onto the machine head mounting frame; the welding flux box is connected onto the machine head mounting frame; andthe array CCD module is connected onto the welding flux box. The linear array CCD based automatic welding seam tracking device is widely applied to the other welding technical fields of submerged-arcwelding and the like.

Description

technical field [0001] The invention relates to the technical field of submerged arc welding, in particular to a linear array CCD-based automatic welding seam tracking device and method. Background technique [0002] As we all know, submerged arc welding has the advantages of high automation, high production efficiency, good weld formation, and no arc radiation. High-tech industrial production has higher and higher quality requirements for thick plate welding, which makes submerged arc welding have increasingly broad application prospects. [0003] During the submerged arc welding operation, the submerged arc welding torch should always correspond to the position of the weld seam. However, due to the offset between the guide rail of the welding trolley and the position of the weld seam, and the invisible arc under the flux layer, etc., the welding head and welding seam often occur. The seam deviation phenomenon seriously affects the welding quality. In order to ensure that...
