Automatic laser welding work station and working method

Abstract

The invention provides an automatic laser welding working method. The working method comprises the following steps that a workpiece to be welded is installed at the position of a tool platform, whether the workpiece is arranged on the tool platform or not is detected through the material detecting system, whether the workpiece is in the correct welding position or not is detected, whether the sizeof the workpiece installed every time is the same or not is detected, the welding seam tracking system is used for carrying out visual detection on the position of the workpiece to be welded, the coordinate deviation numerical difference between the position to be welded and a pre-calibration position is calculated, the numerical difference is read by utilizing the calibration software of the self-contained in the laser head, so that the laser emitted by the laser head is controlled to be in the correct welding position, and the welding seam is tracked; the robot is used for welding, three different-sensitivity photoelectric sensors of the monitoring system collect light of three different section wavelengths to detect the stability of molten pool and whether the surface quality of the weld joint is continuous and uniform. According to the automatic laser welding work station and working method, the intelligent level of laser welding is improved, the precision of the product welding process is improved, and the product quality is ensured.

Description

technical field [0001] The invention relates to the technical field of automatic welding, in particular to an automatic laser welding workstation and a working method. Background technique [0002] With the advancement of manufacturing automation and intelligent production and the needs of customers, higher challenges are posed to the development of laser welding technology. Due to the relatively high environmental requirements of laser welding operations, it is difficult for conventional work areas to meet the requirements of laser welding, making it difficult to ensure the welding quality of products and the safety of the production process, which will greatly reduce production efficiency and increase costs.

Problems solved by technology

Due to the relatively high environmental requirements of laser welding operations, it is difficult for conventional operation areas to meet the requirements of laser welding, making it difficult to guarantee the welding quality of products and the safety of the production process, and will greatly reduce production efficiency and increase costs

[0003] In the process of laser welding and cutting, a lot of spatter is usually generated, and the temperature of the working area is high, especially in the process of continuous operation, accompanied by a lot of laser radiation and noise, which will cause unforeseen effects on the human body. s damage

[0004] The traditional welding process has macroscopic defects such as uneven welds, false welding and undercuts, the welding process is unstable, and pores and cracks are generated in the weld

Moreover, the level of intelligence is not high and the production efficiency is low
