Description

Technical Field

[0001] The utility model relates to the technical field of laser equipment, in particular to a laser processing equipment capable of extracting smoke. Background Art

[0002] Among the processes used to process workpieces, laser engraving and laser cutting are among them. Compared to traditional machining techniques, laser processing technology offers numerous advantages: it can process a wide range of metals and non-metals, particularly materials with high hardness, brittleness, and high melting points (such as ceramics and silicon wafers commonly used in the electronics industry). The laser "knife" used in this process eliminates tool wear; there is no cutting force affecting the workpiece, resulting in minimal deformation; the high energy injection rate minimizes the heat-affected zone (HAZ) and minimizes thermal deformation; it can process parts within sealed containers through transparent media, such as sensors through quartz windows; and it offers high speed, noiselessness, and pollution-free processing. Combining laser beams with CNC systems enables the cutting of complex parts and patterns, eliminating the need for molds. This significantly shortens processing cycles and reduces costs, making it particularly suitable for rapid product changeovers to meet ever-changing market demands. Because laser engraving and laser cutting materials are partially charred or melted, they produce a large amount of smoke and dust. This smoke and dust can contaminate the components and laser optical path of the laser, thereby affecting the performance of the laser. In particular, contamination of the reflector and focusing mirrors in the laser's external optical path can seriously affect the performance of the laser and reduce the laser's stability. The large amount of smoke produced pollutes the environment and is detrimental to the health of laser operators. Laser cutting machines typically use a smoke extraction device to remove the smoke and dust generated during the processing; however, the smoke extraction end of current smoke extraction devices is mostly aimed at the position of the workpiece to be processed. This causes the workpiece position to shift during the extraction process, affecting the processing accuracy. Summary of the Invention

The equipment has a novel structure, an XY-axis moving mechanism adjusts the position of the adsorption platform, and utilizes vacuum adsorption holes to adsorb and fix the workpiece, ensuring that the workpiece is not easily loosened or shifted during processing; due to the effect of the smoke extraction ring groove, the negative pressure end of the smoke extraction head is prevented from being directly aligned with the product, causing the product to loosen or shift, thereby improving the reliability and stability of the operation and processing, and being able to exhaust smoke, improve the processing cleanliness, and avoid smoke and dust pollution.
