Embodiment Construction

[0038] In order to make the purpose and technical solution of the present invention more clear, the following will further describe the specific implementation of the present invention in detail with reference to the drawings and specific examples.

[0039] from figure 1 It can be seen that the self-circulation blowing adsorption device of this embodiment includes two parts: a cavity part and an air circuit part. The cavity part is the main part of the device, which is used to generate negative pressure and clamp and fix the workpiece 3; It is a supporting part, which is used for the circulation between the adsorption gas and the blowing gas, as well as the gas replenishment of the gas cylinder 10, forming a self-circulating gas path. The laser beam 5 is positioned above the workpiece 3 for processing the workpiece 3 .

[0040] see figure 1 , wherein the chamber part includes the adsorption disc 1, the separator 2, the exhaust port 13, the exhaust fan 4 and the motor 7. The...

Abstract

The invention belongs to the field of laser machining and particularly relates to a self-circulating gas blowing adsorption device and a laser machining method. The device mainly comprises a cavity portion and a gas circuit portion. The cavity portion comprises an adsorption disc, a partition plate located in a cavity of the adsorption disc, and an exhausting device located on the partition plate.The gas circuit portion comprises a first connecting pipe, a second connecting pipe, a third connecting pipe and an electromagnetic valve. One end of the first connecting pipe, one end of the secondconnecting pipe and one end of the third connecting pipe are connected with the electromagnetic valve. The other end of the first connecting pipe is connected with an exhausting opening. The other endof the second connecting pipe is connected with an external gas bottle. The other end of the third connecting pipe points to the machining portion. The self-circulating gas blowing adsorption devicesolves the problems that when an adsorbing type clamping method is adopted for fixing a machined object, gas is wasted severely, waste gas generated by adsorption is recycled and used for auxiliary gas blowing in the laser machining process, waste of the gas is reduced, the utilization efficiency is improved, and the whole device is compact in structure, simple and easy to operate and suitable forindustrial application.

Description

technical field [0001] The invention relates to the field of laser processing, in particular to a self-circulating air blowing adsorption device and a processing method. Background technique [0002] Laser processing is to use the energy of light to reach a high energy density at the focus point after being focused by the lens, and to process by the photothermal effect. Laser processing does not require tools, the processing speed is fast, the surface deformation is small, and various materials can be processed. Use laser beams to perform various processing on materials, such as drilling, cutting, scribing, welding, heat treatment, etc. Certain substances with metastable energy levels will absorb light energy under the excitation of external photons, so that the number of atoms at high energy levels is greater than the number of atoms at low energy levels—the number of particles is reversed. If there is a beam of light irradiated, the number of photons The energy is equal ...
