Description

Technical Field

[0001] The utility model belongs to the technical field of laser welding, and particularly relates to a mold locking anti-falling mechanism. Background Art

[0002] Fiber lasers are important ultrashort pulse laser output devices. Their basic performance and stability indicators directly impact the stability and reliability of the system. Currently, various fiber lasers have been widely used in social production and scientific research. Among them, the self-starting and maintenance-free functions of fiber lasers are essential for their industrialization. Self-starting means that the mode-locked laser can start and output mode-locked pulses upon power-up. Maintenance-free means that the mode-locked laser can achieve mode-locked pulse output in a variety of complex environments, such as high temperature, low temperature, vibration, high humidity, and other harsh environments.

[0003] In laser welding, the fiber laser usually needs to be installed on the upper mold. The lower mold is linked to the product to be welded and moves from bottom to top to the position of the upper mold and is locked with the upper mold. During the laser welding process, the lower mold is not firmly fixed, which can easily cause the lower mold and the product to fall, thereby affecting the laser welding effect.

[0004] Based on this, it is necessary to improve the defects in the existing technology to overcome the shortcomings in practical applications. Utility Model Content
