Description

Technical Field

[0001] The present invention relates to the technical field of glass cover plate cutting, and specifically provides a glass cover plate fixed-length cutting device. Background Art

[0002] With the rapid development of fields such as consumer electronics, smart home, and automotive displays, as a core component for screen protection, touch interaction, and appearance decoration, the market demand for glass cover plates continues to grow.

[0003] Especially in scenarios such as smartphones, tablets, and in-vehicle central control screens, glass cover plates need to have high light transmittance, wear resistance, and precise dimensional tolerances, which pose higher requirements for the cutting process during production.

[0004] After retrieval, a Chinese patent with the publication number CN211284152U discloses a glass plate cutting table. This device has a simple structure, is convenient and practical. The lifting of the pressing frame presses and positions the glass plate for fixation, which has a protective effect on the surface of the glass plate. It is cut by a diamond cutting knife, with good cutting effect, neat cut edges, and high efficiency, and is easy to promote and apply. However, there are still the following several problems:

[0005] 1. When cutting a glass plate, it is usually necessary to perform fixed-length cutting on the glass plate. When measuring the length to be cut by this device, manual measurement is required. The efficiency of manual measurement is slow and prone to deviation. Therefore, how to quickly and accurately perform fixed-length cutting of the cutting length during the cutting process of the glass plate is an urgent problem to be solved.

[0006] 2. During the cutting process, the glass plate is conveyed by a transmission device. During the conveying process, the glass plate is prone to tilting, which ultimately leads to skewing during cutting. Therefore, how to solve the problem of the glass plate tilting during the conveying process is also an urgent problem to be solved. Summary of the Invention

[0038] Refer to Figures 1-7 , a glass cover plate fixed-length cutting device, including a workbench 1. At least three feeding conveyor belts 2 with the same interval and synchronous transmission are arranged at the right side position of the upper surface of the workbench 1. At least three discharging conveyor belts 3 with the same interval and synchronous transmission are arranged at the left side position of the upper surface of the workbench 1. And the feeding conveyor belt 2 and the discharging conveyor belt 3 are close but not in contact with each other. A cutting assembly 4 for cutting the glass plate is arranged between the feeding conveyor belt 2 and the discharging conveyor belt 3. A fixed-length assembly 5 for measuring the length of the glass plate is arranged on one side of the workbench 1 close to the discharging conveyor belt 3. Limiting assemblies 6 for blocking both sides of the glass plate are arranged on both sides of the workbench 1. When in use, first place the glass plate to be cut on the feeding conveyor belt 2, adjust the fixed-length assembly 5 to the required length. When the glass plate contacts the fixed-length assembly 5, it can be cut by the cutting assembly 4. The cut glass plate is output through the discharging conveyor belt 3. When the glass plate is conveyed on the feeding conveyor belt 2 and the discharging conveyor belt 3, its both sides are limited by the limiting assemblies 6.

[0039] In the present invention, the cutting assembly 4 includes a U-shaped frame 401 fixedly connected to the upper surface of the workbench 1 by bolts. A linear electric actuator 402 is fixedly connected to the outer wall of the top of the U-shaped frame 401 by bolts. The output end of the linear electric actuator 402 passes through the inner wall of the top of the U-shaped frame 401 and is fixedly connected to a cross plate 403 by bolts. A linear motor module 404 is fixedly connected to the lower surface of the cross plate 403 by bolts. A tool holder 405 is fixedly connected to the mover of the linear motor module 404 by bolts. At least three cutting knives 406 in the same straight line are fixedly connected between the inner walls on both sides of the tool holder 405 by bolts. One end of each of the two circular rods 407 is slidably arranged along the vertical direction on the U-shaped frame 401. On one side of each of the two circular rods 407, there is a circular rod 408 slidably connected to the U-shaped frame 401 along the vertical direction. A connecting block 409 is fixedly connected between the upper ends of the circular rod 407 and the circular rod 408 on the same side. The lower ends of the two circular rods 407 are both fixedly connected to the cross plate 403. A connecting spring 410 is fixedly connected to the lower ends of the two circular rods 408. A pressing frame 411 is fixedly connected between the lower ends of the two connecting springs 410. A vibration pump 413 is fixedly connected to the upper surface of the pressing frame 411. A rubber protective pad 412 is fixedly connected to the lower surface of the pressing frame 411. The height of the rubber protective pad 412 is lower than that of the cutting knife 406 when the connecting spring 410 is in the natural stretched state. After the glass plate contacts the T-shaped baffle 510 of the fixed-length component 5, first start the linear electric actuator 402 to extend. During the extension of the linear electric actuator 402, the cross plate 403 and the linear motor module 404 thereon are driven to move downward, so that the cutting knife 406 on the tool holder 405 moves downward. When the cutting knife 406 is in close contact with the glass plate, start the linear motor module 404 to make the tool holder 405 move horizontally back and forth to cut the glass plate; while the cross plate 403 moves downward, it will drive the pressing frame 411 to move downward through the circular rod 407 and the circular rod 408, so that the rubber protective pad 412 at the bottom of the pressing frame 411 contacts the glass plate. After the cutting is completed, start the vibration pump 413 to separate the cut glass plate. After the cutting is completed, start the discharge conveyor belt 3 to output the cut glass plate. After the glass plate is cut by the provided cutting assembly 4, start the vibration pump 413 to separate the glass plate, avoiding the situation that there are uncompletely cut parts between the glass plates, resulting in the glass plates being unable to be output.

[0040] In the present invention, the fixed-length component 5 includes an avoidance opening 501 formed in the workbench 1. Between the inner walls on both sides of the avoidance opening 501, two symmetric sliding rods 502 are fixedly connected by bolts. A sliding table 503 is slidably connected to the two sliding rods 502. On the lower surface of the workbench 1 and on both sides of the avoidance opening 501, a guiding frame 504 is fixedly connected by bolts. A sliding plate 505 is slidably connected to the guiding frame 504. One side of the guiding frame 504 and one side of the sliding plate 505 are fixedly connected by bolts with a multi-joint electric telescopic rod 507. A cylinder 508 is provided on the sliding plate 505. The output end of the cylinder 508 is fixedly connected by bolts with a support table 506. On the upper surface of the support table 506, two symmetric T-shaped baffles 510 are provided, and the T-shaped baffles 510 pass through the sliding table 503 and are slidably connected thereto. Between two of the support legs of the workbench 1, a scale plate 511 is fixedly connected by bolts. An indicating frame 512 is slidably connected to the scale plate 511. One side of the indicating frame 512 is fixedly connected by bolts with a connecting rod 509, and one end of the connecting rod 509 is fixed to one side of the sliding plate 505. The side of the T-shaped baffle 510 close to the cutting component 4 and the side of the indicating frame 512 close to the cutting component 4 are in the same plane. When it is necessary to adjust the length of the glass plate to be cut, the multi-joint electric telescopic rod 507 is started to expand and contract to drive the sliding plate 505 to slide along the guiding frame 504, and at the same time drive the indicating frame 512 to slide along the scale plate 511. When it moves to the required length, the multi-joint electric telescopic rod 507 is stopped. The cylinder 508 is started to extend so that the two T-shaped baffles 510 on the support table 506 move upward to block the glass plate. After the cutting is completed, the cylinder 508 is started to contract so that the T-shaped baffles 510 are completely separated from the glass plate, and then it can be output through the discharge conveyor belt 3. In this way, the glass plate can be cut with a fixed length. By providing the fixed-length component 5, not only can the length of the glass plate to be cut be measured, but also the glass plate can be blocked during the cutting process, further ensuring the cutting accuracy.

[0041] In the present invention, the limiting component 6 includes two sets of symmetric fixing plates one 601 fixedly connected to the lower surface of the workbench 1 by bolts, and each set has two symmetric ones. One side of each of the multiple fixing plates one 601 is fixedly connected with a sliding column 602 by bolts. A sliding frame 603 is slidably connected to each of the multiple sliding columns 602, and the two sets of sliding frames 603 on both sides are arranged in a mirror image. One end of the sliding frame 603 is fixedly connected with a mounting plate 604 by bolts. A plurality of limiting rollers 605 with the same interval are rotatably connected to the lower surface of the mounting plate 604. A fixing rod 608 is fixedly connected between the two sliding frames 603 on the same side by bolts. Square plates 609 are fixedly connected to the lower surfaces of the two fixing rods 608 by bolts. Two symmetric fixing plates two 606 are fixedly connected to the middle position of the lower surface of the workbench 1 by bolts. A bidirectional lead screw 607 is rotatably connected through the two fixing plates two 606. The two ends of the bidirectional lead screw 607 respectively pass through the two square plates 609 and are threadedly connected thereto. The threaded parts at both ends of the bidirectional lead screw 607 extend from one side of the fixing plate two 606 to its end. When it is necessary to limit the two sides of the glass plate, by rotating the bidirectional lead screw 607, the two sets of sliding frames 603 thereon move towards each other or away from each other, so that the limiting rollers 605 thereon contact the two sides of the glass plate. Through the provided limiting component 6, the two sides of the glass plate can be limited during the conveying process, preventing the situation of skew during the conveying process and thus affecting the cutting accuracy.

[0042] When the present invention is in use, it is divided into the following steps:

[0043] S1: When it is necessary to adjust the cutting length of the glass plate, start the multi-joint electric telescopic rod 507 to expand and contract, drive the sliding plate 505 to slide along the guiding frame 504, and at the same time drive the indicating frame 512 to slide along the scale plate 511. When it moves to the required length, stop the multi-joint electric telescopic rod 507;

[0044] S2: After the adjustment is completed, place the glass plate on the feeding conveyor belt 2. Start the air cylinder 508 to extend, so that the two T-shaped baffles 510 on the support platform 506 move upward to block the glass plate. When cutting after the glass plate contacts the T-shaped baffles 510, first start the electric push rod 402 to extend. During the extension of the electric push rod 402, drive the cross plate 403 and the linear motor module 404 thereon to move downward, so that the cutter 406 on the tool holder 405 moves downward. When the cutter 406 is in close contact with the glass plate, start the linear motor module 404 to make the tool holder 405 move horizontally back and forth to cut the glass plate;

[0045] S3: While the cross plate 403 moves downward, it will drive the pressing frame 411 to move downward through the first round rod 407 and the second round rod 408, so that the rubber protection pad 412 at the bottom of the pressing frame 411 contacts the glass plate. After cutting is completed, start the vibration pump 413 to separate the cut glass plate. After cutting is completed, start the discharge conveyor belt 3 to output the cut glass plate;

[0046] S4: After cutting is completed, start the cylinder 508 to contract, so that the T-shaped baffle 510 is completely separated from the glass plate, and then it can be output through the discharge conveyor belt 3. By repeating this process, the glass plate can be cut to a fixed length;

[0047] S5: When it is necessary to limit the two sides of the glass plate, rotate the bidirectional lead screw 607 to make the two sets of sliding frames 603 on it move towards or away from each other, so that the limiting rollers 605 on them contact the two sides of the glass plate.

[0048] The technical features of the above embodiments can be combined arbitrarily. For the sake of brevity of description, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, it should be considered that the scope described in this specification.

[0049] The above-described embodiments merely represent several implementation manners of the present invention. Their descriptions are relatively specific and detailed, but they should not be construed as limiting the scope of the present invention. It should be noted that for those of ordinary skill in the art, without departing from the concept of the present invention, several modifications and improvements can still be made, and these all belong to the protection scope of the present invention. Therefore, the protection scope of the present invention should be subject to the appended claims.
