Description

Technical Field

[0001] This utility model relates to laser cutting technology, and in particular to a laser cutting device. Background Technology

[0002] Laser cutting technology is widely used in the processing of metal and non-metal sheets due to its high precision and efficiency. However, existing laser cutting equipment still faces the following technical challenges in practical applications:

[0003] An unreasonable support structure affects processing quality and the integrity of the sheet metal: Existing equipment often uses a single-piece flat plate as the support structure for the sheet metal to be processed. Waste generated during cutting (such as metal shavings and non-metallic residues) easily accumulates between the flat plate surface and the bottom of the sheet metal. On the one hand, waste accumulation hinders heat diffusion in the laser cutting area, leading to excessively high local temperatures and affecting the smoothness of the cut edges; on the other hand, prolonged contact and friction between the waste and the bottom of the sheet metal can easily cause scratches on the bottom surface, reducing the finished product yield.

[0004] Insufficient positioning precision can easily lead to cutting deviations: Existing positioning mechanisms mostly use a single cylinder driving a single-sided clamping plate, making it difficult to precisely control the clamping force and unable to adapt to plates of different widths and thicknesses. When the plate size changes, the clamping plate position needs to be manually adjusted, which is cumbersome and inefficient. At the same time, a single clamping point can easily lead to uneven force on the plate, causing slight displacement of the plate during cutting, which in turn causes cutting path deviations and reduces processing accuracy.

[0005] Dust not cleaned in time will pollute the processing environment and equipment: Laser cutting will generate a lot of dust. Existing equipment relies on external dust collection devices for dust collection, which has a limited collection range. Some dust can easily drift into the equipment (such as the transfer module and positioning mechanism). Long-term accumulation will wear down mechanical parts and shorten the service life of the equipment. At the same time, dust adhering to the surface of the sheet will affect the energy transmission of the laser, resulting in a decrease in cutting quality.

[0006] Dust in the processing environment can interfere with the surface quality of the sheet material: suspended dust in the processing environment can easily adhere to the surface of the sheet material to be processed. During laser cutting, dust will absorb some of the laser energy, resulting in uneven cutting depth. In addition, dust will also form stains on the cutting edges, increasing the workload of subsequent cleaning processes.

[0007] In view of the shortcomings of the existing technologies, there is an urgent need to design a laser cutting device that can solve multiple problems such as support, positioning, stability, and cleaning, so as to improve processing accuracy, sheet material quality and equipment reliability.
