Problems solved by technology
[0003] In view of this, the embodiment of the present application provides a welding method, device, system and electronic equipment based on pre-scanning to solve the problem of batch welding of workpieces by teaching fixed points when completing the teaching operation in the prior art, which is easy to occur. The technical problem that the weld deviates from the standard teaching position due to non-standard fixtures and differences between the same batch of workpieces
Especially for curved surface welds, when existing welding robots weld curved surface welds by means of fuzzy tracking and offset compensation, there are technical problems such as the teaching of fixed points for curve welds that often affects work efficiency and unsatisfactory welding results.

Embodiment Construction
[0053] In the following description, specific details such as specific system structures and technologies are presented for the purpose of illustration rather than limitation, so as to thoroughly understand the embodiments of the present application. It will be apparent, however, to one skilled in the art that the present application may be practiced in other embodiments without these specific details. In other instances, detailed descriptions of well-known systems, devices, circuits, and methods are omitted so as not to obscure the description of the present application with unnecessary detail.
[0054] The pre-scan-based welding method provided in this application proposes to perform welding operations in a scan playback manner, especially for welding operations on curved surface welds. This welding method avoids the technical defect that the welding seam deviates from the standard teaching position due to non-standard fixtures and differences between the same batch of workp...

The present application provides a welding method, device, system and electronic equipment based on pre-scanning. The method includes: obtaining at least one weld image by pre-scanning the weld to be welded, wherein the weld image and the to-be-welded Corresponding to a weld point in the welding seam; obtain the coordinate information of the weld point in the world coordinate system according to the weld image; generate the coordinate information of the weld point in the world coordinate system according to the A welding track corresponding to the weld seam to be welded, so as to perform a welding operation according to the generated weld seam track. The above method can generate a welding track containing multiple weld point positions by pre-scanning the weld to be welded, and perform welding operations according to the welding track, avoiding the deviation of the weld from the standard teaching position due to non-standard fixtures and differences in the workpiece itself. problem, and the welding effect is good and the work efficiency is high.
Description
technical field [0001] The present application belongs to the field of welding automation technology, and in particular relates to a welding method, device, system and electronic equipment based on pre-scanning. Background technique [0002] In the welding operation, in order to improve the control accuracy of the welding operation and the quality monitoring of the weld during the welding operation, the positioning effect is mainly improved by setting a tracking positioning device at the welding head of the welding robot. Welding robots can improve efficiency, optimize quality, and improve working conditions. Most of the current welding robots are programmable teaching robots. This kind of robot welds workpieces in batches by teaching fixed points when completing the teaching operation. The technical problem that the welding seam deviates from the standard teaching position due to the standard and the differences between the same batch of workpieces. Especially for curved s...
