The invention provides a gas-assisted laser machining device. The device comprises a sealing cover used for covering a workpiece located on a workbench, a sealing cavity is formed in the sealing cover, optical glass is arranged at the top of the sealing cover, blowing assemblies used for blowing machining auxiliary gas into the sealing cavity are arranged on the side portion of the sealing cover,and the other side portion of the sealing cover is provided with an exhaust assembly communicating with the sealing cavity and used for exhausting machining waste gas. According to the device, when machining is carried out, a laser carries out laser machining on the workpiece through the optical glass, due to the fact that the blowing assemblies blow the machining auxiliary gas into the sealing cavity, the surface of the workpiece to be machined is located in the environment of the auxiliary machining gas, and at the moment, laser spots can complete corresponding laser machining on the workpiece through sparse filling density and low energy threshold value, so that the quality requirement of a laser light source is lowered, and the laser machining efficiency is improved; and the exhaust assembly can exhaust the machining waste gas in time so that heat on the surface of the workpiece can be taken away, and the heat influence on machining is reduced.
Description
【Technical field】 [0001] The invention relates to a laser gas-assisted processing device. 【Background technique】 [0002] The laser stainless steel coloring process is widely applied to the logo and button marks on the surface of high-end white goods. Laser marking technology is different from traditional printing technology in that it has the characteristics of non-contact, no ink consumption, and durable color. The laser stainless steel surface coloring process uses laser radiation on the stainless steel surface to induce local oxidation and discoloration on the stainless steel surface to form gorgeous colors. However, the conventional laser stainless steel color marking process is difficult to control, requires a special laser source and the processing speed is slow, and the slow scanning of the high-frequency laser can easily cause thermal deformation of the stainless steel surface. 【Content of invention】 [0003] The technical problem to be solved by the present inv...
