A gear 13, the first gear 13 is connected to the output end of the second motor 11, a fixing frame 19 is also provided on the support frame 21, a storage plate 8 is provided inside the fixing frame 19, a second rack 10 is provided at one end of the storage plate 8, a connecting rod 5 is also provided on the storage plate 8, a groove 14 is provided on one side of the storage plate 8, a third rack 15 is provided on the groove 14, a threaded rod 17 is also provided on the fixing frame 19, a second gear 16 is provided on the threaded rod 17, and a steel brush 18 is also provided on the threaded rod 17.

[0025] During cutting, the flexible substrate to be cut is placed on the placement plate 8, and the second motor 11 is turned on to drive the first gear 13 to rotate. The rotation of the first gear 13 drives the first rack 9 to move. The movement of the first rack 9 drives the movable baffle 7 to move. The movement of the movable baffle 7 keeps the dust cover 4 closed, which prevents impurities generated by cutting from splashing, thereby protecting the operator, avoiding impurities generated by cutting from splashing and causing environmental pollution, and making it convenient for the operator to clean the device.

[0026] At the same time, the first gear 13 rotates to drive the second rack 10 to move, and the movement of the second rack 10 drives the storage plate 8 to move toward the high-speed rotary knife 6 to cut the device, which plays the role of automatically pushing the flexible substrate, thereby achieving the effect of automatically cutting the flexible substrate and avoiding errors caused by human operation that affect the cutting accuracy.

[0027] At the same time, when the storage plate 8 moves forward to cut the flexible substrate, the third rack 15 drives the second gear 16 to rotate, and the rotation of the second gear 16 drives the threaded rod 17 to rotate, driving the steel brush 18 to move, so as to clean the high-speed rotary knife 6, thereby preventing the high-speed rotary knife 6 from cutting the flexible substrate for a long time, causing impurities to adhere to the high-speed rotary knife 6, affecting the cutting accuracy, and at the same time preventing the high-speed rotary knife 6 from being offset due to long-term cutting, thereby affecting the cutting efficiency.

[0028] A dust removal pipe 22 is provided on the outer shell 12, and the dust removal pipe 22 is connected to the equipment. Impurities generated by long-term cutting accumulate inside the device. The impurities in the device are sucked out through the dust removal pipe 22 to prevent the accumulation of impurities generated by cutting from affecting the operation of the device, and at the same time facilitate the operator to clean the device.

[0029] The first gear 13 is meshed with the first rack 9, and the first gear 13 is also meshed with the second rack 10. The second motor 11 is turned on to rotate and drive the first gear 13 to rotate. The rotation of the first gear 13 drives the first rack 9 to move, so that the first baffle 3 moves to form a seal for the device, preventing the flying of cutting magazines from causing environmental pollution, and facilitating cleaning by operators. At the same time, the rotation of the first gear 13 drives the second rack 10 to move, and drives the storage plate 8 to move, so that the high-speed rotary knife 6 cuts the flexible substrate, achieving the effect of automatic cutting, and avoiding the influence of human operation on the cutting accuracy.

[0030] A gap is provided inside the first baffle 3, and its size is adapted to the movable baffle 7. The movable baffle 7 is provided inside the first baffle 3. The first gear 13 rotates to drive the first rack 9 to move, thereby driving the movable baffle 7 to move in the gap. When it moves to the top, it fits with the dustproof shell 4, so that the device is closed, and the substrate to be cut is placed on the placement plate 8 before cutting begins.

[0031] The third rack 15 is meshed with the second gear 16, and the second gear 16 is confined in the groove 14. The rotation of the first gear 13 drives the second rack 10 to move, drives the storage plate 8 to move, drives the third rack 15 to move, and causes the second gear 16 to rotate. The second gear 16 is confined inside the groove 14, so the second gear 16 can only rotate and cannot move, causing the threaded rod 17 to rotate out of the fixed frame 19, driving the steel brush 18 to move. When it moves to one end, the steel brush 18 is squeezed with the high-speed rotary cutter 6 to clean the impurities attached to the high-speed rotary cutter 6 during cutting, to prevent excessive impurities from being attached to the high-speed rotary cutter 6 due to long-term cutting, affecting the accuracy of the high-speed rotary cutter 6 in cutting the flexible substrate, and at the same time prevent the impurities generated by the cutting from being attached to the high-speed rotary cutter 6 for a long time, affecting the service life of the high-speed rotary cutter 6.

[0032] The placement plate 8 is connected by a connecting rod 5, and a gap is set on the placement plate 8 for cutting. Before starting cutting, the substrate is placed on the placement plate 8, and the substrate is cut through the gap on the placement plate 8. At the same time, the substrate is fixed by the fixing frame 19 and pushed along the gap of the fixing frame 19 to avoid human operation affecting the cutting accuracy.

[0033] The first rack 9 is connected to the movable baffle 7. When the first rack 9 moves to the top, the movable baffle 7 also moves to the top, and the movable baffle 7 fits with the dustproof shell 4 to keep the equipment airtight. When the cutting is completed, the first gear 13 reverses to drive the first rack 9 to move, and drives the movable baffle 7 to move, return to the gap of the first baffle 3, and place the flexible substrate on the placement plate 8 again, and repeat this reciprocating cycle.

[0034] The support frame 21 is provided with holes inside for collecting waste residues generated by cutting. Because the equipment is closed during cutting, impurities will not fly out of the equipment, but will stay inside the equipment to avoid pollution to the environment. At the same time, it is convenient for the staff to clean the equipment from the dust removal pipe 22.

[0035] The second rack 10 is connected to the storage plate 8 and moves in the gap of the fixing frame 19 to prevent the substrate from being pushed manually, which would cause a large error in cutting accuracy and affect the cutting accuracy.

[0036] This embodiment also discloses a method for using the high-precision cutting device for a flexible substrate, comprising the following steps: Step 1: Place the flexible substrate on the placement plate 8 and fix it with a fixing frame 19. After the fixation is completed, first turn on the first motor 2 to drive the connecting rod 20 to rotate, drive the high-speed rotary cutter 6 to rotate, and then turn on the second motor 11 to drive the first gear 13 to rotate, drive the second rack 10 to move, drive the placement plate 8 to move, and perform cutting.

[0037] Step 2: At the same time, the first gear 13 rotates to drive the first rack 9 to rotate, and drives the movable baffle 7 to move and fit the dustproof shell 4.

[0038] Step 3: At the same time, the placement tray 8 moves to drive the third rack 15 to move, drive the second gear 16 to rotate, drive the threaded rod 17 to rotate, drive the steel brush 18 to move, and clean the high-speed rotary cutter 6.

[0039] Working principle: When cutting, place the flexible substrate to be cut on the placement plate 8, turn on the second motor 11, drive the first gear 13 to rotate, the first gear 13 rotates to drive the first rack 9 to move, the first rack 9 moves to drive the movable baffle 7 to move, the movable baffle 7 moves to keep the dust cover 4 closed, so as to prevent the impurities generated by cutting from splashing, thereby protecting the operator, avoiding the impurities generated by cutting from splashing and causing environmental pollution, and making it convenient for the operator to clean the device. At the same time, the first gear 13 rotates to drive the second rack 10 to move, and the second rack 10 moves to drive the placement plate 8 to move toward the high-speed rotary cutter 6. The device is cut to automatically push the flexible substrate, so as to achieve the effect of automatically cutting the flexible substrate, and avoid errors caused by human operation affecting the cutting accuracy. At the same time, when the placement plate 8 moves forward to cut the flexible substrate, the third rack 15 drives the second gear 16 to rotate, and the rotation of the second gear 16 drives the threaded rod 17 to rotate, and drives the steel brush 18 to move to clean the high-speed rotary knife 6, so as to prevent the high-speed rotary knife 6 from cutting the flexible substrate for a long time, causing impurities to adhere to the high-speed rotary knife 6, and affecting the cutting accuracy. At the same time, it is prevented that the high-speed rotary knife 6 is offset due to long-term cutting, and the cutting efficiency is affected.

[0040] Impurities generated by long-term cutting are accumulated inside the device. The impurities in the device are sucked out through the dust removal pipe 22 to prevent the accumulation of impurities generated by cutting from affecting the operation of the device. At the same time, it is convenient for the operator to clean the device. The second motor 11 is turned on to rotate and drive the first gear 13 to rotate. The rotation of the first gear 13 drives the first rack 9 to move, so that the first baffle 3 moves to form a seal for the device to prevent the cutting magazines from flying around and causing environmental pollution. At the same time, it is convenient for the operator to clean. At the same time, the rotation of the first gear 13 drives the second rack 10 to move, and drives the storage plate 8 to move, so that the high-speed rotary knife 6 cuts the flexible substrate, achieving the effect of automatic cutting, avoiding In order to avoid the influence of human operation on the cutting accuracy, the movable baffle 7 is arranged inside the first baffle 3, and the first gear 13 rotates to drive the first rack 9 to move, and drives the movable baffle 7 to move in the gap, and when it moves to the top, it fits with the dust cover 4 to form a closed device, and before the cutting starts, the substrate to be cut is placed on the placement plate 8, and the first gear 13 rotates to drive the second rack 10 to move, drive the placement plate 8 to move, and drive the third rack 15 to move, so that the second gear 16 rotates, and the second gear 16 is restricted in the groove 14, so the second gear 16 can only rotate but not move, causing the threaded rod 17 to be removed from the fixed frame 19. The steel brush 18 is driven to move when it moves to one end, and the steel brush 18 is squeezed with the high-speed rotary knife 6 to clean the impurities attached to the high-speed rotary knife 6 during cutting, so as to prevent excessive impurities from being attached to the high-speed rotary knife 6 due to long-term cutting, thereby affecting the precision of the high-speed rotary knife 6 in cutting the flexible substrate, and at the same time, prevent the impurities generated by cutting from being attached to the high-speed rotary knife 6 for a long time, thereby affecting the service life of the high-speed rotary knife 6. Before starting to cut, place the substrate on the placement plate 8, cut the substrate through the gap on the placement plate 8, and fix the substrate through the fixing frame 19 at the same time, and push the substrate along the gap of the fixing frame 19 to avoid manual operation. The cutting accuracy is affected. When the first rack 9 moves to the top, the movable baffle 7 also moves to the top. The movable baffle 7 fits with the dust cover 4 to keep the equipment airtight. When the cutting is completed, the first gear 13 reverses to drive the first rack 9 to move, drive the movable baffle 7 to move, return to the gap of the first baffle 3, and place the flexible substrate on the placement plate 8 again, and repeat this cycle. Holes are provided inside the support frame 21 to collect waste residue generated by cutting. Because the equipment is closed during cutting, impurities will not fly out of the equipment, but stay inside the equipment to avoid pollution to the environment. At the same time, it is convenient for staff to clean the equipment from the dust removal pipe 22.

[0041] The second rack 10 is connected to the storage plate 8 and moves in the gap of the fixing frame 19 to prevent the substrate from being pushed manually, which would cause a large error in cutting accuracy and affect the cutting accuracy.
