Description

Technical Field

[0001] The invention relates to the technical field of laser positioning devices, in particular to a non-woven fabric laser positioning device. Background Art

[0002] The non-woven fabric laser positioning device is a device used for precise positioning and cutting in the production process of non-woven fabrics. The device uses laser technology to achieve precise marking or cutting of non-woven fabric materials. It usually includes a laser, a laser scanning device, a control system, and a laser beam focusing device. The computer controls the precise position of the laser beam to accurately position or cut the non-woven fabric surface to ensure the processing quality and efficiency of the non-woven fabric. Laser positioning has the advantages of high precision, non-contact, and high-speed processing, so it is widely used in the production, processing, or splicing of non-woven fabrics.

[0003] During the laser cutting process, non-woven fabrics will be locally vaporized, decomposed and melted under the heat of high-energy lasers, resulting in smoke and slag. These byproducts are scattered in the cutting area, causing many interferences to laser positioning and transmission. First, the large number of tiny particles contained in the smoke will cause scattering effects on the laser beam. According to the principle of light scattering (Rayleigh scattering and Mie scattering theory), when a laser beam passes through smoke containing particles, scattering occurs. This effect weakens the energy of the beam and causes its propagation path to shift, thereby causing positioning errors. Secondly, the adhesion of slag further interferes with the optical path. The slag will be deposited on the surface of the material or on the optical elements of the equipment, causing secondary reflection or attenuation of the laser beam during propagation, affecting the integrity of the optical path and positioning accuracy. In addition, smoke and slag release heat at high temperatures, forming local thermal disturbances. This thermal disturbance changes the air density in the cutting area, thereby affecting the refractive index of the air and causing a slight shift in the transmission path of the laser beam. This refractive index change is particularly important for high-precision cutting tasks, directly affecting the cutting effect and quality. In summary, the interference of smoke and slag on laser transmission and positioning is mainly reflected in the scattering effect, thermal disturbance and optical interference caused by material adhesion. These factors need to be fully considered and optimized in the design of high-precision laser cutting equipment. Summary of the invention

[0016] (III) Beneficial effects

[0017] Compared with the prior art, the present invention provides a non-woven fabric laser positioning device, which has the following beneficial effects:

[0018] 1. The non-woven fabric laser positioning device is set up by using an air suction mechanism. The driving motor is turned on to drive the driving gear. The driving gear drives the fan blades to rotate through the driving gear ring. The fan blades drive the outside air to pass through the filter and enter the inner ring cavity on the inner wall of the inner ring, so that the air near the laser positioning part is effectively sucked in, and the particle impurities are adsorbed on the filter, waiting to be cleaned when shut down, thereby keeping the laser positioning part clean during operation and reducing the interference of smoke and impurities, further improving the cutting accuracy. At the same time, the air in the inner ring cavity on the inner wall of the inner ring part enters the outer ring cavity between the inner ring part and the protective cover, and then is discharged through the outer ring cavity between the inner ring part and the protective cover, forming a circulating flow of air. This air flow process can effectively take away the smoke and slag in the cutting process, while maintaining the cleanliness of the laser positioning part and the protective cover, reducing the interference of impurities in the environment, ensuring the stability and high precision of the laser optical path, thereby further improving the accuracy and efficiency of the cutting operation.

[0019] 2. The non-woven fabric laser positioning device is set up with a dust removal mechanism. The fan blades drive the ring to rotate by driving the connecting rod. Since the fan blades drive the outside air to pass through the filter and enter the inner ring, the outside air passes through the air inlet groove on the ring, and then passes through the connecting groove and is discharged through the exhaust port. The exhaust port drives the dust on the filter to be blown into the collection tank. This design helps to maintain the accuracy of the laser positioning system and reduce interference factors by effectively cleaning the filter and ensuring the normal operation of the air intake and dust removal systems, thereby improving the use efficiency and cutting quality of the device.

[0020] 3. The non-woven fabric laser positioning device is arranged by a rotating mechanism. The air blown out of the outer ring cavity between the inner ring and the protective cover drives the impeller to rotate. The impeller drives the hemispherical block to rotate, and the fabric is rotated and resisted. The hemispherical block contacts the surface of the fabric and applies a driving force, thereby helping the cut fabric to move smoothly. BRIEF DESCRIPTION OF THE DRAWINGS
