Description

Technical Field

[0001] This application relates to the field of laser glass cutting technology, and more particularly to a laser cutting device for glass processing. Background Technology

[0002] Laser cutting of glass is a processing technology that uses a high-power laser beam to cut glass through precisely controlled thermal energy. The principle is that the laser beam concentrates heat, causing the glass material to heat up rapidly in the heated area. This temperature difference causes cracks to form in the glass, thus achieving a precise cut. The advantages of laser cutting include high precision, no mechanical contact, smooth cut edges, suitability for complex shapes and challenging cutting tasks, and it is commonly used in the production and manufacturing of glass sheets.

[0003] Existing technologies, such as the invention patent with publication number CN119282423A, disclose a laser cutting method and apparatus. This patent includes emitting a laser and expanding and focusing the laser beam; adjusting the focal point of the laser to the surface of the glass to be cut; driving the annular cutting track to rotate the glass about a rotation axis, so that the focal point of the annular cutting track moves relative to the glass along an annular virtual line; controlling the focal point of the annular cutting track to move cyclically along the cutting trajectory, the cutting trajectory at least partially passing through the annular virtual line of the annular cutting track, the plane containing the cutting trajectory forming an angle with the thickness direction of the glass to be cut; controlling the focal point of the annular cutting track to move continuously or periodically along the thickness direction of the glass to be cut; and turning off the laser after the glass to be cut is completed. This application can solve the technical problem that cutting glass tubes with three laser beams reduces the flatness of the cut end face of the glass tube.

[0004] In the production and processing of glass sheets, it has been found that the traditional method of cutting glass is to score and break it. However, using scoring wheels or other methods to cut glass will scratch the glass and generate glass dust. Laser cutting can be used to cut glass. During this process, the temperature at the crack of the laser-cut glass will be high. Since glass is a brittle material, uneven local temperature changes will cause thermal stress, which will lead to cracks or thermal stress cracks in the glass. Summary of the Invention

A protective pad 611 is fixedly connected to the inner wall surface of the inlay plate 610. The protective pad 611 is a silicone pad. The surface of the protective pad 611 abuts against the side wall surface of the glass plate 9.

[0060] Working principle: The laser cutting module 11 generates a high-energy laser beam, which is precisely cut along the surface of the glass plate 9 by the linear moving module 3. After the laser is focused, it does not contact the glass, and the laser beam is guided to the front surface and passes through the glass plate. The laser beam is pulsed at a frequency of 10kHz to 30kHz and irradiates the sacrificial substrate 8. The beam is moved through the glass plate at a speed of 30 mm / s to 90 mm / s. The beam ablates the sacrificial substrate 8. In response to the ablation of the sacrificial substrate 8, superheated steam is generated. The superheated steam is used to ablate the back side of the glass plate, thereby cutting the glass plate. This avoids glass chipping caused by mechanical stress. At the same time, the moving frame 2 is precisely moved along the surface of the slide rail 7 by the electric drive module 10 to ensure the accuracy of the laser cutting path and the repeatability of the positioning.

[0061] Cooling and protection mechanism 4: During the cutting process, the laser will cause local heating of the glass, and the molten glass may affect the cutting accuracy. The cooling and protection mechanism 4 continuously provides cooling airflow through the axial flow fan 401, and sprays the cooling airflow directly onto the cutting seam area through the nozzle 405 to quickly cool the molten glass. At the same time, the filter column 408 is a water-wet column. When the cooling airflow passes through the inner chamber of the filter column 408, it can filter particulate matter in the air, ensuring that the sprayed air remains humid and clean, avoiding contamination of the glass surface and dust reduction operation. At the same time, the angle of the rotating adjustment rod 412 and the nozzle 405 can be flexibly adjusted according to the cutting needs to adapt to different cutting angles.

[0062] Ejection Mechanism 5: The ejection mechanism 5 is used to ensure that the sacrificial substrate 8 can be quickly ejected and replaced after long-term use, and that the cut glass can be ejected smoothly. The cylinder 501 drives the moving frame 503 to move, and the two ends of the moving frame 503 will slide with the limit rod 504. At the same time, the moving frame 503 drives the limit plate 505 to move horizontally. At this time, the slot 509 opened on the surface of the limit plate 505 slides and limits the pulley 508. Since the cross section of the limit plate 505 is stepped, the support column 511 at the upper end of the sliding frame 507 can slide through the support plate 502 for ejection operation. At the same time, the spring 510 generates a squeezing force to reset the sliding. The design of the support plate 502 and the spring 510 structure helps to reduce shaking during operation and improve the stability and durability of the equipment.

[0063] Positioning mechanism 6: The positioning mechanism 6 controls the movement of the inlay plate 610 through four connecting plates 601 and drive rod 602, ensuring that the glass plate 9 remains stable and accurately positioned during the cutting process. Through the cooperation of the adjusting frame 608 and the sliding plate 609, the drive rod 602 is rotated, allowing the adjusting frame 608 at both ends of the drive rod 602 to slide along the sliding rod 607. At the same time, the inlay plate 610 fixed on the lower surface of the adjusting frame 608 can squeeze and limit the four corner surfaces of the glass plate 9. The positioning mechanism 6 can achieve precise positioning of the glass plate 9 and prevent deviation during the cutting process. The protective pad 611 protects the surface of the glass plate 9 to avoid scratches or damage.
