[0002] As a core component of display panels, the quality of liquid crystal glass substrates directly impacts the screen's display quality, lifespan, and the ultimate consumer experience. During the production process of TFT-LCD (liquid crystal display) liquid crystal glass substrates, ensuring the quality of the liquid crystal glass is key to maintaining product high performance and market competitiveness. This process not only requires a high degree of technical precision, but also crucially controls the quality of the liquid crystal glass, enabling the timely detection and removal of defective products to ensure that every liquid crystal glass substrate meets established quality standards. The inspection process, in particular, is an essential step in the entire production process, ensuring quality control and problem resolution. Multiple inspections are conducted throughout the production process to ensure that each step meets quality requirements.

First, manual operations are susceptible to subjective factors, leading to biased inspection results. Second, the use of steel tape measures and glass cutters for positioning and cutting at specific points is not only inefficient, but also tedious and complex manual sampling and cutting during spot checks. Furthermore, handling oversized glass often carries the risk of breakage. This not only wastes production resources but also poses environmental and personnel safety risks. Summary of the Invention

[0018] The present utility model provides a device for positioning, cutting and sampling of glass. Through the precise coordination of the laser emission system and the cutting positioning system, the position of the sampling work is set by the servo unit, and then the glass is cut by the laser emission system. The laser emitter can emit a precisely controlled light beam, and the servo unit ensures that the laser emitter can accurately move according to the preset path, thereby achieving the purpose of glass sampling.

[0031] The present invention is described in further detail below with reference to the accompanying drawings:

[0032] See also Figure 1 , the utility model provides a device for positioning, cutting and sampling of glass, including a laser emission system and a cutting positioning system;

[0033] The laser emission system is installed on the cutting and positioning system. The laser emission system is equipped with a laser emitter 2 and a servo unit. The cutting and positioning system is equipped with a gantry module 3. The laser emitter 2 is movably mounted on the gantry module 3. The first servo motor 1 in the servo unit is connected to the laser emitter 2. The positioning adjustment of the laser emitter 2 is achieved by the first servo motor 1, which mainly copes with the adjustment of the working height after power adjustment for glass of different thicknesses. The servo unit's rapid response and high-precision control capabilities enable the laser emitter 2 to quickly and accurately locate the designated position on the glass. As the core component of the device, the laser emitter 2 is capable of emitting a precisely controlled light beam. The laser emitter 2 is responsible for emitting a precisely controlled light beam to cut the positioned glass. These light beams are not only highly linear and focused, but can also be adapted to different cutting requirements by adjusting the power and frequency. The precision of the laser beam ensures the smoothness and accuracy of the cut edge.

[0034] Gantry module 3 is mounted on mounting profile 5. Gantry module 3 serves as the support frame for the entire cutting and positioning system, boasting high strength and rigidity. Mounting profile 5 provides a stable mounting foundation for the entire device, ensuring the relative positioning and stability of all components. A work platform 4 is located within mounting profile 5. Made of high-temperature-resistant material, work platform 4 can withstand the high temperatures generated during the cutting process, preventing heat damage to the laser cutting machine while maintaining flatness and stability, ensuring the stability and durability of the device in prolonged high-temperature environments. Guide rails are located on both sides of gantry module 3, providing a stable path for the laser emitter and other moving components. Positioning rails are located vertically between the two guide rails of gantry module 3, further enhancing vertical positioning accuracy. Laser emitter 2 is mounted on the positioning rails. The guide rails and positioning rails of gantry module 3 are connected to the drive shaft of the second servo motor via a coupling. Both the guide rails and positioning rails of gantry module 3 are driven by the second servo motor. A second servo motor drives the laser emission system forward, backward, and left and right on the gantry module 3, enabling precise adjustment of the cutting position. Gantry module 3 uses a single motor to ensure parallelism and perpendicularity between the guide rails, reducing friction and vibration during movement and ensuring high consistency between the work platforms 4 on both sides during operation.

[0035] This utility model achieves high-precision cutting of glass through the precise coordination of the laser emission system and the cutting positioning system. Precise control of the laser beam and rapid response of the servo unit ensure smooth and accurate cutting edges. The entire cutting process is automated, reducing the need for manual intervention. This not only improves production efficiency but also reduces labor intensity and human error. Furthermore, it allows for flexible adjustments based on different cutting requirements. By replacing different laser emitters or adjusting the servo unit parameters, it can adapt to the cutting needs of glass of different sizes, shapes, and materials.

[0036] The above are merely preferred embodiments of the present invention and are not intended to limit the present invention. Those skilled in the art will readily appreciate that the present invention is susceptible to various modifications and variations. Any modifications, equivalent substitutions, or improvements made within the spirit and principles of the present invention shall be included within the scope of protection of the present invention.
