Description

Technical Field

[0001] The present invention relates to the technical field of liquid crystal glass cutting, and in particular to a liquid crystal glass double-blade cutting machine and a cutting method. Background Art

[0002] Liquid crystal glass usually refers to a special glass structure, which consists of two glass substrates sandwiching a layer of liquid crystal material. This structure is mainly used to manufacture liquid crystal displays and other related products.

[0003] In the production of liquid crystal displays, multiple liquid crystal display units are usually made on a large glass substrate, and then the large glass substrate needs to be cut into small pieces according to the predetermined size for assembly. Existing cutting machines usually use a single blade cutting method, that is, using a blade to cut along the predetermined cutting line. However, this cutting method has the following problems: Low efficiency: After the front of the liquid crystal glass is cut, it needs to be turned over manually or by an automatic flipping machine before the back of the liquid crystal glass can be cut. This flipping process not only reduces production efficiency, but also increases the complexity of the operation.

[0004] Risk of damage: During the flipping process of the LCD glass, the front side of the LCD glass is prone to cracking, causing liquid crystal leakage, thus affecting the quality and pass rate of the product.

[0005] Cutting quality: When the cutter wheel cuts the LCD glass, it will leave debris on the cutting path on the LCD glass surface. If these debris are not cleaned up in time, the cutter wheel needs to move back and forth along the cutting path, which will cause the debris to affect the cutting effect of the cutter wheel on the LCD glass, and in severe cases, even cause the LCD glass to crack and the liquid crystal to leak out.

So that the cutting head 7 can start cutting from the side of the liquid crystal glass, the positioning rod 3 will not hinder the movement of the cutting head 7, the upper part of the mounting frame 1 is slidably connected with a sliding plate 4, the right end of the sliding plate 4 slides through the positioning rod 3, and a square hole 401 is opened in the middle of the sliding plate 4, the top and bottom surfaces of the sliding plate 4 are connected with guide rails 5, the number of guide rails 5 is two, and a servo drive system 6 is installed on the two guide rails 5.

[0036] Since the upper cutting blade 7 will generate flying debris when cutting the top surface of the liquid crystal glass, and the flying debris will fall on the top surface of the liquid crystal glass due to gravity, thereby scratching the top surface of the liquid crystal glass, a protective mechanism is designed, such as Fig.11 and Fig.12As shown, the protection mechanism includes a connecting seat 31, a driving motor II 32, a rotating rod 33, a sliding frame 34, an electromagnet 3401, an iron sheet 3402, an electrostatic adsorption film 3403 and a locking assembly. The connecting seat 31 is connected to the upper left portion of the rear side of the mounting frame 1, the driving motor II 32 is connected to the connecting seat 31, the rotating rod 33 is rotatably connected to the connecting seat 31, the shape of the rotating rod 33 is the shape of a cylinder cut by a vertical plane, and its side surface consists of an arc surface and a plane, and the rear side surface of the rotating rod 33 is a vertical plane, and the left end of the rotating rod 33 is connected to the output shaft of the driving motor II 32, and the lower part of the sliding frame 34 is provided with a sliding groove whose shape is compatible with the rotating rod 33, so that the sliding frame 34 can move freely left and right on the rotating rod 33, and the rotating rod 33 can drive the sliding frame through its own vertical plane. 34 rotates, a plurality of electromagnets 3401 are evenly spacedly installed on the front side of the sliding frame 34, an iron sheet 3402 is adsorbed on the front side of the electromagnet 3401 by magnetic force, an electrostatic adsorption film 3403 is connected to the front side of the iron sheet 3402, and the electrostatic adsorption film 3403 can also be replaced by a nano-markless adhesive tape, and a locking assembly is used to lock the sliding frame 34; the locking assembly includes an electric push rod 35 and a locking block 36, the electric push rod 35 is connected to the right part of the rear side of the mounting frame 1, the locking block 36 is connected to the telescopic rod of the electric push rod 35, a semi-cylindrical groove is opened on the top surface of the locking block 36, the right end of the rotating rod 33 is placed in the semi-cylindrical groove of the locking block 36, the left side surface of the locking block 36 and the right side surface of the sliding frame 34 are both flat and contact each other, so that the locking block 36 can block the right side of the sliding frame 34 to limit and lock the sliding frame 34.

[0037] A cutting method of a liquid crystal glass double-blade cutting machine: When it is necessary to cut the liquid crystal glass, firstly, the liquid crystal glass can be placed on the left side of the top surface of the sliding plate 4, and the position of the liquid crystal glass can be adjusted so that the front side surface and the right side surface of the liquid crystal glass are in contact with the contact surface 301 of the positioning rod 3, and the positioning rod 3 can initially position the liquid crystal glass, and then the screw rod II 17 is driven to rotate by the driving motor I 16, and the screw rod II 17 can drive the clamping plate 15 to move forward, and the clamping plate 15 can drive the limiting block 18 to move forward, and the front side of the clamping plate 15 is in contact with the rear side surface of the liquid crystal glass. The clamping plate 15 cooperates with the positioning rod 3 to clamp and fix the liquid crystal glass to prevent the liquid crystal glass from deviating in the front and rear directions. At this time, the front side of some limiting blocks 18 will contact the rear side surface of the liquid crystal glass, and the limiting blocks 18 of the above part will be compressed into the inside of the clamping plate 15, and the corresponding reset spring 19 will be compressed, while the limiting blocks 18 that are not squeezed and compressed into the inside of the clamping plate 15 by the liquid crystal glass will be respectively located on the left and right sides of the liquid crystal glass, thereby blocking the left and right sides of the liquid crystal glass, playing a limiting role, and preventing the liquid crystal glass from deviating in the left and right directions; then the servo motor can be used to cut the liquid crystal glass. The machine 12 drives the screw rod Ⅰ13 to rotate forward and reversely, thereby driving the sliding plate 4 to move left and right. The sliding plate 4 can drive the guide rail 5, the servo drive system 6 and the cutting head 7 to move left and right, adjust the position of the cutting head 7, align the cutting head 7 with the predetermined longitudinal cutting path on the liquid crystal glass, and then drive the cutting head 7 to move forward and backward along the guide rail 5 through the servo drive system 6. The two cutting heads 7 can cut the top and bottom surfaces of the liquid crystal glass respectively, thereby improving the cutting efficiency; during the cutting process, the top surface of the fixing rod 8 and the bottom surface of the fixing ring 11 can contact the top and bottom surfaces of the liquid crystal glass respectively, thereby limiting the position of the liquid crystal glass to prevent the liquid crystal glass from turning up and down, thereby ensuring the cutting effect; during the cutting process, debris may splash onto the surface of the liquid crystal glass in front of the cutting head 7, thereby affecting the subsequent cutting effect of the cutting head 7, so air can be blown around the cutting head 7 through the air pump Ⅱ28, the air outlet pipe 29 and the annular nozzle 30, thereby blowing away the debris remaining on the surface of the liquid crystal glass in front of the cutting head 7, thereby ensuring the cutting effect;At the same time, the bristles 26 can sweep the debris remaining on the cutting path of the cutting head 7, and at the same time, the air in the fixed cylinder 20 can be extracted through the air pump Ⅰ22 and the exhaust pipe 23, so that a negative pressure is formed in the fixed cylinder 20, so that the hollow plate 25 can generate suction near the end of the bristles 26, so that the debris remaining on the cutting path of the cutting head 7 can be sucked away, so that the debris can enter the fixed cylinder 20 through the hollow plate 25, the hollow frame 9 and the connecting pipe 24 in turn, and the filter cartridge 2101 can filter the debris, so that the debris stays in the fixed cylinder 20 and does not enter the air pump Ⅰ22, which is convenient for the subsequent same treatment. At the same time, during the cutting process of the cutting head 7, the rollers 27 and the rollers are used to filter the debris. The cooperation of the beads 1001 can make the rotating ring 10 and the hollow plate 25 rotate freely (the principle of the universal wheel), so as to ensure that the hollow plate 25 can always be located behind the moving path of the cutting head 7, so as to ensure that the hollow plate 25 can accurately absorb the debris remaining on the cutting path of the cutting head 7; since the servo drive system 6 has the function of driving the cutting head 7 to rotate (existing technology), when the predetermined longitudinal cutting path on the liquid crystal glass is completely cut, the servo drive system 6 can drive the cutting head 7 to rotate ninety degrees, and then the moving mechanism and the servo drive system 6 cooperate to control the cutting head 7 to align with the predetermined transverse cutting path on the liquid crystal glass and cut. ;

[0038] After the liquid crystal glass is fixed, the rotating rod 33 can be driven by the driving motor II 32 to rotate ninety degrees, and the rotating rod 33 can drive the sliding frame 34 to rotate forward ninety degrees. The sliding frame 34 can drive the electromagnet 3401, the iron sheet 3402 and the electrostatic adsorption film 3403 to rotate forward ninety degrees, so that the electrostatic adsorption film 3403 is adsorbed on the top surface of the liquid crystal glass, and then the electromagnet 3401 is controlled to be powered off, so that the electromagnet 3401 no longer adsorbs the iron sheet 3402, and then the driving motor II 32 drives the rotating rod 33 to reverse ninety degrees, and the rotating rod 33 can be driven by the driving motor II 32 to rotate upward ninety degrees to reset, and the sliding frame 34 can drive the electromagnet 3401 to rotate upward ninety degrees to reset, so that the electromagnet 3401 is separated from the iron sheet 3402. At this time, the iron sheet 3402 can be temporarily fixed on the top surface of the liquid crystal glass due to the action of the electrostatic adsorption film 3403, and the two adjacent iron sheets 3402 are The gap between the two ends of the liquid crystal glass vertically coincides with the predetermined cutting path on the liquid crystal glass, thereby not hindering the upper cutting head 7 from cutting the top surface of the liquid crystal glass. This can prevent the flying debris from falling on the top surface of the liquid crystal glass due to gravity and scratching the top surface of the liquid crystal glass. Repeating the above operation can re-attract the iron sheet 3402 through the electromagnet 3401 to drive the iron sheet 3402 and the electrostatic adsorption film 3403 to rotate upward and reset, so that the electrostatic adsorption film 3403 is separated from the top surface of the liquid crystal glass. The electrostatic adsorption film 3403 can be reused due to its own characteristics and will not leave any marks on the top surface of the liquid crystal glass. When the liquid crystal glass needs to be cut into different sizes, the locking block 36 can be driven by the electric push rod 35 to move downward and separate from the rotating rod 33, so that the locking block 36 no longer blocks the right side of the sliding frame 34, and then the sliding frame 34 can be pulled out to the right to replace the sliding frames 34 of different sizes.

[0039] The above description is only a specific implementation mode of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can easily think of changes or substitutions within the technical scope disclosed by the present invention, which should be covered by the protection scope of the present invention.
