[0002] Laser processing technology, with its advantages of high processing precision, small heat-affected zone, high processing efficiency and non-contact processing, has become a core technology in the glass product processing field. It is widely used in the marking and cutting processes of various glass products such as building, electronic and daily-use glass, meeting the fine and diversified processing needs of glass products. This invention is a multi-purpose laser marking and cutting device.

[0003] In existing technologies, most glass processing equipment is designed to adapt to a single specification. If it is necessary to switch to processing different specifications of glass, it is often necessary to replace the special processing equipment or make complicated adjustments to the conveyor line structure. This is not only inconvenient to operate, but also seriously affects the processing adaptability and overall work efficiency. At the same time, most glass processing equipment has relatively simple functions, making it difficult to achieve integrated processing of multiple glass processing steps. It cannot provide a reliable guarantee for the precise cutting of large glass, and the processing flow is seriously fragmented. Summary of the Invention

It can simultaneously perform continuous operations of laser marking, label printing, and labeling on small glass, and integrated operations of laser cutting, laser marking, label printing, and labeling on large glass. This achieves customized processing for various glass sizes without requiring equipment changes or structural adjustments, significantly improving processing adaptability and operational efficiency. Furthermore, it integrates core functions of laser marking, labeling, and laser cutting. The marking process uses an ultraviolet laser marking head to meet the requirements for fine marking on the glass surface, while the cutting process is equipped with a nanosecond infrared laser cutter and sensors for visual positioning, temperature monitoring, and breakage detection, providing a fundamental guarantee for precise cutting of large glass. This achieves integrated processing of multiple glass processing steps. Through a linkage control module, the dual conveyor belt conveyor line, marking and labeling module, and laser cutting module operate in a coordinated manner, eliminating the need for manual operation at each step and achieving automated glass processing. This effectively reduces human intervention and further improves overall processing efficiency.

[0016] Furthermore, in this invention, the visual positioning sensor can complete glass positioning calibration and automatic compensation for processing accuracy, ensuring the precision of the processing position from the source; the infrared temperature sensor and the glass breakage detection sensor transmit real-time detection data to the linkage control module, and the system can automatically adjust the cutting power and inert gas jet volume according to the temperature threshold of the processing area. When glass breakage is detected, the machine stops immediately, effectively avoiding processing scrap and material waste, and significantly improving product yield. The inert gas synchronously assists cutting and optimizes the glass cutting process. The gas nozzle of the laser cutting module sprays high-pressure inert gas synchronously with the cutting operation, which not only isolates the air to avoid high-temperature oxidation of the cutting surface to produce burrs and burnt edges, but also cools the processing area, reducing the possibility of glass cracking due to high temperature, and improving the flatness and smoothness of the cutting surface.

[0017] Furthermore, the dual conveyor belt conveyor line of this invention has an adjustable height function. Through the linkage structure of the drive shaft, eccentric wheel, connecting rod and telescopic cylinder, the support rod can drive the conveyor belt to adjust the height, which can adapt to the workstation height requirements of different processes such as marking, cutting and labeling. Moreover, the support of the support plate on the conveyor belt ensures the stability of the glass conveying process and avoids processing deviations caused by the shaking of the conveying surface.

[0018] Furthermore, the linkage control module of this invention features a rich and convenient CNC system configuration, a built-in database of processing parameters for different types of glass, supports the import of CAD / AI files and allows for preset processing flows, enabling one-click automated operation. The equipped touch screen interface allows for visual setting of processing parameters, real-time monitoring of the processing flow and query of historical data. The normally closed physical emergency stop button ensures the safety of emergency shutdown. The built-in fault self-diagnosis system can also automatically detect the operating status of each module and display fault codes, reducing the operating threshold and maintenance difficulty of the equipment.

At the same time, the parameters can be flexibly adjusted according to processing needs, greatly improving the adaptability of the equipment to different glass processing processes and ensuring the processing quality of marking and cutting.

[0048] The working principle of this invention: When the equipment is working, the linkage control module 12 coordinates and regulates the operation. Based on the specifications of the glass being processed, the corresponding conveyor belt 21 of the double conveyor belt conveyor line 2 is selected. The telescopic cylinder 216 drives the connecting plate 2142 to rotate the transmission shaft 214 and the eccentric wheel 2141. The connecting rod 2143 ensures that the four transmission shafts 214 move synchronously, pushing the support rod 24 to adjust the support plate 241 and the conveyor belt 21 to the appropriate processing height. The drive motor 221, in conjunction with the gearbox 22, drives the conveyor belt 21 to rotate. After the glass is conveyed to the designated workstation, the pendulum-type travel limit switch 23 triggers a signal and transmits it to the linkage control module 12. If it is a small glass, it is conveyed by the left conveyor belt 21. The motion control module 12 controls the operation of the marking and labeling module 4. The first motor 413, in conjunction with the reducer 412, drives the marking and labeling module 4 to move laterally along the toothed plate and track on the side plate 3. The first reduction motor 423 drives the first moving seat 42 to make slight adjustments back and forth along the first crossbeam 41. The second reduction motor 424 drives the first lead screw 426 to rotate through the belt pulley transmission, driving the lifting frame 43 to rise and fall, realizing the three-dimensional precise positioning of the laser marking device 431. After completing the fine marking on the glass surface, the thermal printer 44 prints the label, and the flexible labeling unit 45 completes the labeling operation.

The infrared temperature sensor 5361 monitors the temperature of the processing area in real time, and the glass breakage detection sensor 5362 monitors the glass processing status. The detection data is transmitted to the linkage control module 12 in real time. The CNC system automatically adjusts the power of the nanosecond infrared laser cutter 535 and controls the gas spray according to the temperature threshold. The nozzle 5363 increases or decreases the amount of inert gas injected. If glass breakage is detected, all processing steps are stopped immediately. After laser cutting is completed, the marking and labeling modules 4 on both sides complete the laser marking and labeling of large glass simultaneously or in stages. Throughout the processing, the CNC system of the linkage control module 12 can access the built-in glass processing parameter database, supports the import of CAD / AI files and one-click automated operation according to the preset process. The touch screen enables visual setting of processing parameters, real-time monitoring of the processing process and query of historical data. The normally closed physical emergency stop button can realize emergency shutdown of the equipment. The fault self-diagnosis system automatically detects the operating status of each module and displays fault codes to ensure stable and orderly operation of the equipment.
