Embodiment Construction

[0050] The present invention is described in detail below in conjunction with examples, but the present invention is not limited to these examples.

[0051] figure 1 It is a structural schematic diagram of the water-conducting laser processing device of the present invention.

[0052]The water-conducting laser processing device of the present invention includes a table mirror 2 and a coupling water cavity 3; the table mirror and the coupling water cavity are sequentially arranged coaxially along the laser transmission direction. Wherein, the terrace reflector 2 may be in the shape of a circular truncated truncated mirror, or may be in the shape of a multi-edged (≥3) truncated prism, and is used to input the central beam of the laser 1 into the coupling water chamber after undergoing total reflection and guiding light. The central beam of 1 is transformed into an edge beam through total reflection, and together with the original edge beam of laser 1, it is input to the couplin...

Abstract

The invention discloses a water guide laser processing device and a processing system. The device comprises a table-shaped reflector and a coupling water cavity which are coaxially arranged in sequence along a transmission direction of laser, the table-shaped reflector is used for inputting the central beam of the laser into the coupling water cavity after total reflection light guide, and transmitting the laser guided by total reflection along a water column emitted from the coupling water cavity, and a workpiece is cut by using the laser in the water column. The invention further discloses awater guide laser processing system comprising the device. According to the invention, the central beam of the laser is converted into an edge beam by using the table-shaped reflector, so that the power distribution of the laser finally emitted from the coupling water cavity is more uniform, the taper effect when the water guide laser cuts the workpiece is improved, and the depth processing capability is expanded.

Description

technical field [0001] The application relates to a water-conducting laser processing device and a processing system, belonging to the technical field of laser processing. Background technique [0002] With the rapid development of medical, aviation, aerospace, and semiconductor fields, the performance requirements for key components are getting higher and higher, which promotes the improvement and improvement of parts processing methods and equipment. In the field of parts cutting and processing, the traditional cutting processing methods are mainly mechanical cutting and high-pressure water cutting. However, the above processing methods have the problems of low processing efficiency and low processing accuracy. In order to solve the above problems, those skilled in the art have developed a laser cutting processing device, which is superior to traditional cutting processing methods in terms of processing efficiency, processing accuracy and environmental protection. Howeve...
