An anti-collision protection device for laser welding with swing head

Abstract

The invention provides an anti-collision protection device for laser welding of a swing head. The anti-collision protection device comprises a swing head main body and further comprises a swing head protection window, a first protection device, a second protection device and an anti-collision protection inductor, wherein the swing head protection window is arranged at the lower end of the swing head main body; the first protection device is connected to the lower end of the swing head protection window and is used for achieving impact dropping in the X and Y directions; the second protection device is connected to the lower end of the first protection device and is used for achieving impact lifting in the Z direction; and the anti-collision protection inductor is arranged on the swing headprotection window and is used for sensing whether the first protection device and the second protection device are impacted or not, and the anti-collision protection inductor is electrically connected with a control host of welding equiopment. According to the anti-collision protection device, the simultaneous collision avoidance of the X, Y and Z directions can be achieved, even if the swing head is impacted, the swing head can also recover quickly, and the progress of a project cannot be affected; and after the impact occurs, the equipment can give an alarm for a first time, so that the equipment is stopped, secondary damage to the equipment is avoided, and the occurrence of production safety accidents in the field is reduced.

Description

technical field [0001] The invention relates to the technical field of laser processing, in particular to an anti-collision protection device used for swinging head laser welding. Background technique [0002] Laser welding is an efficient and precise welding method that uses a high-energy-density laser beam as a heat source. It has the advantages of small heat input, high energy conversion rate, large weld depth and width, and easy automation and intelligence. [0003] As the market demand for product technology is getting higher and higher, the laser welding process of the swing head is widely accepted in the market. Compared with the traditional collimation welding head and galvanometer welding head, the products welded by the swing welding head : The welding seam is more uniform and the appearance is more beautiful. With the deepening of the application, the application of some complex laser welding conditions will also appear. The laser welding of the swing head needs ...

AI Technical Summary

Problems solved by technology

With the deepening of the application, the application of some complex laser welding conditions will also appear. The laser welding of the swing head needs to cooperate with many moving mechanisms on site. This process (especially during debugging) is very easy to happen. The risk of being hit by the swing head will greatly affect the progress of the project and increase the occurrence of on-site safety accidents. This puts forward higher requirements for the anti-collision protection of the swing head during laser welding. After the swing head hits, there should be no major damage to the equipment. Damage and to be able to recover quickly without affecting the progress of the project

[0004] At present, in the process of laser welding of the swing head, most of the anti-collision protection mechanisms of the swing head have not been installed and applied, and a small part of the installation is relatively simple, and it cannot achieve the ability to avoid collisions in the X, Y, and Z directions at the same time
