Embodiment Construction

[0023] In order to make the object, technical solution and advantages of the present invention clearer, the present invention will be further described in detail below in conjunction with specific embodiments. It should be understood that the specific embodiments described here are only used to explain the present invention, and do not limit the protection scope of the present invention.

[0024] A welding method, comprising: placing a product to be welded on a conveyor belt, when the product to be welded moves to a visual inspection area, a line laser illuminates the product to be welded, and at the same time takes pictures of the product to be welded by an industrial camera to obtain an image of the product to be welded information;

[0025] The image information is transmitted to a visual industrial computer and processed by a visual algorithm program;

[0026] The visual algorithm program extracts the welding trajectory of the product to be welded, and obtains the coordin...

Abstract

The invention relates to a welding method. The welding method is characterized in that image information of a product to be welded is acquired through an industrial camera and a line laser, a three-dimensional model of the product to be welded on the industrial camera is associated with a welding machine coordinate, the contour coordinate of the three-dimensional model can be converted into a movement trajectory coordinate of a welding machine, and a movement control program on the industrial computer directly drives the welding machine to operate along a welding trajectory for welding througha welding trajectory given by a vision program. The movement control program does not need to be pre-compiled, and the generality is extremely high; and images are automatically acquired through theindustrial camera, and the movement trajectory of the welding machine is obtained through coordinate conversion, errors caused by a tooling and errors of the product can be compensated during welding,and the welding accuracy is improved.

Description

technical field [0001] The invention relates to the field of automatic control, in particular to a welding method. Background technique [0002] Most of the traditional welding robots follow the robot teaching trajectory. The robot always welds according to the pre-taught program, and cannot adjust the welding trajectory in real time according to the production differences of the products in real time, resulting in generally low welding accuracy. In the actual application process, due to the variety of products, it is necessary to teach each different type of product, which brings a lot of workload to the staff, and because of the different types of products, it is necessary to redesign the custom processing special The jig is used to position the product, the design and processing cost of the jig is high, and the versatility of the entire welding system is not strong. Contents of the invention [0003] Based on this, it is necessary to provide a welding method for the de...
