Problems solved by technology

[0005] The purpose of the present invention is to solve the problems of the traditional laser processing system, such as high requirements on the position of the workpiece, inconvenient carrying, and limited processing in many occasions, and provide a hand-held Type laser processing gun system
This system can be applied to the unrestricted work of various laser processing guns. The successful development of hand-held laser processing guns will make laser processing very convenient and flexible, and many problems that could not be welded due to position problems in the past will be greatly solved. Good solution, ready for laser processing

Embodiment Construction

[0013] The present embodiment will be described below in conjunction with FIG. 1 .

[0014] Various entities of the present invention shown in accompanying drawing 1 all relate to the hand-held laser gun system that is suitable for the workpiece of laser processing such as laser welding and cutting in various different positions indoors and outdoors.

[0015] The hand-held laser processing gun system includes a fiber laser 10 , a control system 20 , a laser gun body 30 , a laser nozzle 70 , and a processing gun focusing and moving wheel 60 . Under the control of the control system 20, the fiber laser 10 emits a laser beam with high beam quality. This laser beam can be transmitted through the optical fiber 110. The end connector of the optical fiber 110 can be embedded in the laser gun body 30. The focus system 50 in the gun body comes out through the nozzle 70, and can act on the workpiece that is in contact with the processing gun focus and the moving pulley 60. During proce...

Abstract

The invention discloses a hand-held laser processing gun system, comprising a fiber laser (10), a control system (20), a body of a laser gun (30), a focusing system (50), a laser nozzle (70), a focus-controlling and rotating wheel for the processing gun (60), and an optical fiber. The invention is characterized in that: the fiber laser (10) is connected with the control system (20); the laser is also connected with a laser head integrated in the body of the laser gun (30) through the optical fiber; the focus-controlling and rotating wheel (60) is fixed at the bottom of the body for the laser gun; laser beam from the laser (10) is output by the laser head, and focuses and works on a workpiece through the focusing system (50) and the laser nozzle (70). The invention has the advantages of convenience in portability due to compact size, light weight and good light speed quality of the fiber laser and the characteristics of hand-held laser processing gun, and avoidance of inconvenient manufacturing due to the position, cost and other reasons in the past.

Description

technical field [0001] The invention relates to an effective system capable of performing laser welding, laser cutting and other processing on workpieces at different positions, in particular to a hand-held laser processing gun system. Background technique [0002] Laser processing includes laser welding and laser cutting, etc. Due to the particularity of laser processing, such as the accuracy of the focus point, the size of the spot, and the required accuracy of the optical power density, etc., the relative position between the workpiece and the laser processing head is relatively demanding. high. [0003] In existing laser processing, usually the workpiece can only be processed on a workbench. This can better achieve the processing effect for some workpieces that are suitable for being placed on the workbench for processing. It is very inconvenient to operate and use, and many objects that cannot be moved and placed on the workbench cannot be processed by laser. [0004...
