Description
Technical Field
[0001] The utility model relates to the technical field of liquid crystal glass substrate manufacturing, in particular to a mechanical device for reducing the splashing of glass powder during longitudinal cutting. Background Art
[0002] Liquid crystal substrate glass, an indispensable cornerstone of modern display technology, is manufactured through a process that is a testament to the precision of the art. This material not only bears the heavy responsibility of displaying images, but its quality also directly determines the clarity, color reproduction, long-term operational stability, and even the entire product lifespan of the display product. The key to substrate glass's success in such a demanding field lies in its unique physical properties, such as high light transmittance, low thermal expansion coefficient, and excellent chemical stability. These characteristics require rigorous control at every stage of the production process to ensure near-perfect purity and integrity of the substrate glass.
[0003] However, ensuring this high standard is no easy task in the complex manufacturing process of LCD substrate glass, from raw materials to finished product. The substrate glass is like a microscopic battlefield rife with challenges. Tiny dust particles in the air, imperceptible mechanical debris on the production line, residual chemicals inevitably used during production, and, most problematically, glass powder generated during the slitting process, all pose potential threats to its quality. These contaminants, like invisible enemies, silently erode the substrate glass's pristine surface. Any trace of contamination or damage can become a time bomb that compromises the quality of the final product.
[0004] The slitting process, a critical step in the glass substrate manufacturing process, is of undeniable importance. High-precision cutting technology is used to separate the entire substrate glass into the required dimensions, preparing it for subsequent processing and assembly. However, this seemingly simple cutting process produces a large amount of fine glass powder. These powder particles are extremely small, making them difficult to completely remove through traditional cleaning methods such as spraying and wiping. Not only do they adhere to the substrate surface, causing subtle flaws that affect optical performance, but they can also be reactivated during subsequent handling and processing, further contaminating the substrate. More seriously, the long-term accumulation of glass powder can cause microscopic scratches or cracks on the substrate surface. Although these damages are imperceptible to the naked eye, they significantly reduce the mechanical strength and durability of the substrate glass, ultimately leading to performance degradation or premature failure of the product during use.

[0026] In the prior art, the glass substrate slitting process involves direct cutting of the glass, which produces glass powder that is extremely difficult to clean and easily damages the substrate glass, resulting in a decrease in the yield rate of the glass substrate. Figure 1 As shown, the utility model provides a mechanical device for reducing the splashing of glass powder during longitudinal cutting, including a drive motor and a broken glass baffle.
[0027] The driving motor is connected to the broken glass baffle, which is arranged on the first surface of the substrate glass 3. The positions of the driving motor and the broken glass baffle are adjusted according to the position of the substrate glass 3, and the broken glass baffle and the substrate glass maintain a minimum distance from each other without interfering with each other's movement trajectory.
[0028] The utility model can reduce the pollution and damage to the glass substrate caused by glass powder generated in the longitudinal cutting process of the glass substrate, and improve the yield rate of the glass substrate.
[0029] The driving motor includes a first driving motor 11 and a second driving motor 12 ; the broken glass baffle includes a first broken glass baffle 21 and a second broken glass baffle 22 .
[0030] The first and second cullet baffles 21 and 22 are symmetrically arranged on the first surface of the glass substrate 3 . A first anvil strip 41 is arranged between the first and second cullet baffles 21 and 3 , and a second anvil strip 42 is arranged between the second and second cullet baffles 22 and 3 .
[0031] like Figure 2 As shown, the first anvil strip 41 and the second anvil strip 42 are placed on the first surface of the substrate glass 3, and the second surface of the substrate glass 3 corresponding to the first anvil strip 41 is provided with a first scribing head 51, and the second surface of the substrate glass 3 corresponding to the second anvil strip 42 is provided with a second scribing head 52.

A dust removal device is installed on the second surface of the glass substrate 3 to promptly remove generated dust and prevent it from splashing or floating onto the second surface of the glass substrate 3.

By adjusting the distance of the drive motors, the distance between the cullet baffle and the glass substrate can be controlled, adapting to the production of various glass thicknesses and reducing the impact of process adjustments on glass substrate production. At the same time, the cullet and glass powder generated by slitting are isolated from the glass substrate, thereby improving the yield rate of the glass substrate.
[0036] The present invention will be further explained below with reference to specific embodiments.
[0037] Example
[0038] The first cullet baffle 21 and the second cullet baffle 22 are symmetrically arranged on the first surface of the glass substrate 3. A first anvil strip 41 is arranged between the first cullet baffle 21 and the glass substrate 3, and a second anvil strip 42 is arranged between the second cullet baffle 22 and the glass substrate 3. The anvil strips provide stable support to ensure that the glass substrate 3 does not move or deform unnecessarily during scribing or other processing.
[0039] The first anvil strip 41 and the second anvil strip 42 are placed on the first surface of the substrate glass 3. The second surface of the substrate glass 3 corresponding to the first anvil strip 41 is provided with a first scribing head 51, and the second surface of the substrate glass 3 corresponding to the second anvil strip 42 is provided with a second scribing head 52. The scribing head is used to accurately carve the required lines or patterns on the substrate glass. By controlling the running trajectory and force of the scribing head, microcracks or stress concentration areas can be formed inside the substrate glass 3. These areas are easy to expand along the scribing direction during the subsequent splitting process, thereby achieving precise splitting of the glass. A dust removal device is provided in the direction of the second surface of the substrate glass 3 to absorb the generated dust in time to prevent it from splashing or floating to the second surface of the substrate glass 3. The broken glass baffle can effectively prevent the generated dust from splashing or floating to the first surface of the substrate glass 3.
[0040] The first drive motor 11 and the second drive motor 12 are connected to the transmission support structure, and the transmission support structure is used to support the entire mechanical device of the present invention.
[0041] The first drive motor 11 is connected to the first cullet baffle 21, and the second drive motor 12 is connected to the second cullet baffle 22. The drive motors are used to adjust the distance between the cullet baffle and the horizontal plane of the glass substrate 3, as well as the angle between the cullet baffle and the glass substrate 3. By adjusting the distance of the drive motors, the distance between the cullet baffle and the glass substrate can be controlled, adapting to the production of various glass thicknesses and reducing the impact of process adjustments on glass substrate production. At the same time, the cullet and glass powder generated by slitting are isolated from the glass substrate, thereby improving the yield rate of the glass substrate.
[0042] A driving device is arranged between the driving motor and the glass baffle, and the driving device includes a first driving device and a second driving device.
[0043] A first drive device is provided between the first drive motor 11 and the first cullet baffle 21 to control the position and angle of the first cullet baffle. A second drive device is provided between the second drive motor 12 and the second cullet baffle 22 to control the position and angle of the second cullet baffle. The drive motor, through the drive device, allows the cullet baffle to be flexibly adjusted horizontally and vertically to meet different production requirements.
[0044] The type of driving device can be selected from connecting rod structure, gear transmission, air pump or hydraulic pump.
[0045] The driving motor is connected to the broken glass baffle through a connecting rod mechanism, which converts the rotational motion of the driving motor into the reciprocating or swinging motion of the broken glass baffle, thereby effectively blocking the splashing of glass during the glass cutting process.
[0046] The connecting rod mechanism can be a crank connecting rod and a rocker mechanism.
[0047] The drive motor is connected to the broken glass baffle through a gear transmission. The drive motor transmits power to the gears on the broken glass baffle through the gear box, achieving synchronous or proportional movement. In this way, the drive motor can ensure relatively precise position control or speed matching of the broken glass baffle.
[0048] The driving motor controls the movement of the broken glass baffle by driving an air pump or a hydraulic pump, and uses air pressure or hydraulic pressure to accurately drive the broken glass baffle.
[0049] The drive motor controls the distance between the cullet baffle and the horizontal plane of the substrate glass 3 to ensure that the cullet baffle can effectively block and isolate the cullet and glass powder generated during the slitting process. This adjustment can be made according to the thickness of the substrate glass and production requirements to ensure the best isolation effect.
[0050] In addition to the distance, the drive motor can also adjust the angle between the cullet baffle and the substrate glass. This adjustment further optimizes the isolation of cullet and glass powder, minimizing their impact on substrate glass production quality. Adaptable to various glass thicknesses: Because the drive motor can flexibly adjust the position and angle of the cullet baffle, it can accommodate the production needs of substrate glass of varying thicknesses. This flexibility reduces the need to frequently readjust the production line to accommodate changes in substrate glass thickness, thereby improving production efficiency.
[0051] When production conditions or substrate glass specifications change, the position and angle of the cullet baffle can be quickly adjusted to quickly restore optimal production conditions, thereby reducing potential impacts on glass substrate production quality. Effective isolation of cullet and glass powder is a key factor in ensuring substrate glass yield. By optimizing the configuration and adjustment strategy of the cullet baffle, contamination and damage to the substrate glass by cullet and glass powder can be significantly reduced, thereby improving yield.
