Description

Technical Field

[0001] The present invention relates to the technical field of flat glass substrate manufacturing, and in particular to a cutting device and method suitable for substrate glass. Background Art

[0002] Glass cutting is an important part of the LCD manufacturing industry. As the requirements of customers and users continue to increase, cost pressure is increasing. The current hourly production capacity is no longer enough to meet current production and market needs. The production line needs to continuously increase production capacity to cope with market changes.

[0003] Since the original design of the glass substrate line is based on the original small size and slow beat design, but with the development of the substrate glass industry to large size, customers have higher and higher requirements for glass quality. Under the faster and faster beat, the same material and design method can no longer meet the existing industry use. The original cutting mechanism on site can no longer meet the existing method, the service life is relatively short, and the cost is relatively high.

[0004] It can be seen that the existing technology can no longer solve the practical problems encountered in current production. Summary of the invention

[0005] The object of the present invention is to provide a cutting device and method suitable for substrate glass to overcome the problems existing in the prior art. The present invention can adjust the position after breaking by selecting different arc guide rails to determine different arc centers, that is, the positions of breaking centers, and controlling the distances between different breaking centers; at the same time, the cutting center and the breaking center of the blade are made inconsistent, which can effectively reduce the adverse effects caused by cutting; in addition, the present invention can achieve different effects through different breaking centers and can be used in different industries.

[0006] In order to achieve the above object, the technical solution adopted by the present invention is as follows: A cutting device suitable for substrate glass comprises a frame, a slide device is installed on one side of the frame, the slide device comprises an arc guide rail, the arc guide rail is installed on one side of the frame, a plurality of moving blocks are slidably connected to the arc guide rail, the rear parts of the plurality of moving blocks are connected to an adsorption device through a mounting plate, the adsorption device comprises an adsorption device body, a suction cup is installed on the top of the adsorption device body, a breaking power device is installed between the mounting plate and the frame; a mounting base is fixed on the top of the frame, a cutting board mounting seat is installed on the top of the mounting base, and a cutting board strip is installed on the cutting board mounting seat; a cutter head column is fixed on the other side of the frame, the cutter head column is connected to a cutter head device through a connecting piece, the cutter head device comprises a cutter head device body, a cutting cutter head is installed on the bottom of the cutter head device body, and the cutter head device body is connected to the cutter head column through a connecting piece; Further, the radius of the arc-shaped guide rail is 500-800 mm; Furthermore, the hardness of the cutting board strip is 50-70 HRC.

[0007] A cutting method applicable to substrate glass, based on the above-mentioned cutting device applicable to substrate glass, comprises the following steps: Step 1: Install the arc guide rail of the target radius on one side of the rack, and then install the substrate glass on the anvil strip; Step 2: Breaking off the power device drives the adsorption device to move circumferentially to the bottom of the substrate glass through the arc guide rail, and the suction cup of the adsorption device adsorbs the bottom of the substrate glass; Step 3: After the cutting head of the cutting head device scribes the top surface of the substrate glass according to the center of the cutting head, it stays at the edge of the anvil strip. At this time, the distance between the suction cup and the cutting head is L1, and the distance between the cutting head and the center of the cutting head is L3; Step 4: Determine the breaking center through the marking center of the cutter head, and the breaking center is consistent with the arc center of the arc guide rail; Step 5: The breaking power device drives the adsorption device to move circumferentially through the arc guide rail, and the circumferential movement of the adsorption device generates a pulling force on the substrate glass to break the substrate glass; Furthermore, in step 2, the suction cup adsorption pressure is -0.045~-0.085 Mpa; Furthermore, in step 2, the suction length of the suction cup is L2; Furthermore, L1 and L2 satisfy: 3L2≥L1≥1.5L2; Further, L3 in step 3 is 1-3 mm; Furthermore, the breaking center is determined by the cutter head scoring center in step 4 as follows: the breaking center is the bottom of the substrate glass just below the cutter head scoring center on the top surface of the substrate glass; Furthermore, in the step five, the substrate glass is broken at a breaking angle of 2° to 15°.

[0008] The above technical solution has the following advantages or beneficial effects: The present invention provides a cutting device suitable for substrate glass. By setting an arc guide rail, the center of the arc can be determined; by setting a breaking power device, an adsorption device can be driven to move circumferentially on the arc guide rail, so that the substrate glass can be fixed and broken in a guiding direction; by setting a cutter head device, the cutting center of the cutter head can be determined, so that the positions of the breaking center / arc center and the cutter head cutting center are inconsistent, thereby preventing the adverse effects of cutting on the substrate glass and improving product quality.

[0009] Furthermore, by selecting different arc guide rail radii, the position of the arc center can be changed, that is, the position of the breaking center can be changed to adapt to substrate glasses of various sizes.

[0010] Furthermore, by controlling the hardness of the cutting board strips, the cutting board strips can have a buffering function, and will not deform when the board is broken, thereby preventing the cutting board strips from affecting the breaking result.

[0011] The present invention provides a cutting method suitable for substrate glass, in which a cutter head device is used to perform scoring according to the cutter head scoring center, an adsorption device is used to realize fixation before breaking, and a breaking power device drives the adsorption device to break. The position after breaking is adjusted by determining the center of the arc, that is, the position of the breaking center, and controlling the distances between different breaking centers. At the same time, the cutter head scoring center and the breaking center are made inconsistent, which can prevent obvious pulling and edge rubbing, effectively reduce adverse effects caused by cutting, and is beneficial to improving the quality of broken products.

[0012] Furthermore, by controlling the adsorption pressure of the suction cup, the entire breaking process can be accurately controlled to reduce adverse effects on the substrate glass and improve product quality.

[0013] Furthermore, by flexibly controlling the sizes of L1, L2 and L3, different forms of adsorption can be achieved to achieve different effects, thereby enhancing the flexibility of the device.

[0014] Furthermore, the existing devices often use a method in which the breaking center is consistent with the cutting center of the blade. The present method can prevent obvious pulling and rubbing of the edges by setting the breaking center inconsistent with the cutting center of the blade, thereby effectively reducing the adverse effects caused by cutting.

[0015] Furthermore, by setting the breaking angle, the breaking can be achieved more accurately, and the adverse effects of the breaking on the substrate glass can be prevented, thereby improving the quality of the product. BRIEF DESCRIPTION OF THE DRAWINGS
