Abstract
Description
Technical Field
[0001] This utility model relates to the field of glass processing equipment technology, specifically to a precision cutting device for glass substrate semi-finished products. Background Technology
[0002] High-generation glass substrates are the core materials used to produce large-size liquid crystal display panels. They mainly refer to the glass substrates required for G8.5 generation and above production lines. They are characterized by large size, high flatness, and good chemical stability. In the production process of glass substrates, the precision cutting of semi-finished products is a crucial step.
[0003] Traditional cutting equipment often struggles to meet the high precision and efficiency requirements of advanced glass substrates, frequently resulting in uneven cutting and edge breakage. This not only affects the quality of the glass substrates but also increases production costs. Therefore, developing a device capable of precisely and efficiently cutting semi-finished glass substrates is of great significance for improving the production level and quality of glass substrates. Utility Model Content
[0004] The purpose of this invention is to provide a precision cutting device for glass substrate semi-finished products, so as to solve the problems of easy breakage, low precision and low efficiency when cutting large-size thin glass as mentioned in the background art.
[0005] To achieve the above objectives, this utility model provides the following technical solution: a precision cutting device for glass substrate semi-finished products, comprising a lifting frame and a frame body. The lifting frame is disposed at the upper end of the frame body. A screw is rotatably connected between the two ends inside the lifting frame, and a threaded seat is threaded onto the screw. A motor is fixed to one end of the lifting frame, and the output end of the motor is fixedly connected to the driving end of the screw. An electric guide rail is fixed to the lower end of the threaded seat, and a sliding frame is disposed at the lower end of the electric guide rail. A cutting head is fixed to the lower end of the sliding frame. Positioning frames are fixed to both sides of the lower end of the frame body, and a bidirectional lead screw is rotatably connected between the upper end of the positioning frame and the lower end of the frame body. A motor is fixed to the upper end of the positioning frame, and the motor… The output end is fixedly connected to the drive end of the bidirectional lead screw. The upper and lower ends of the bidirectional lead screw are threaded with threaded seats, and guide blocks and clamping plates are fixed at both ends of the threaded seats. The electric guide rail frame is set longitudinally. When the electric guide rail frame is started, the sliding frame moves back and forth, driving the cutting head to move back and forth. When the second motor is started, the screw rotates, and the threaded seats move along the screw. Through the electric guide rail frame, the cutting head moves left and right, thereby expanding the cutting range of the glass. When the first motor is started, the bidirectional lead screw rotates, driving the threaded seats to move along the bidirectional lead screw. Since the threads at the upper and lower ends of the bidirectional lead screw are opposite, the two threaded seats move closer or further apart, driving the clamping plates to move. The two clamping plates cooperate to clamp and release the glass.
[0006] As a further technical solution of this utility model, a fixed base is fixed on one side of the sliding frame, and a dust collection hood is provided in the middle of the fixed base. The dust collection hood is connected to the dust collection box through a connecting pipe. During the cutting process, the glass fragments and dust generated will be effectively collected by the dust collection hood.
[0007] As a further technical solution of this utility model, a telescopic cylinder is fixed in the middle of the upper end of the frame, and the lower end of the telescopic cylinder is fixedly connected to the upper end of the lifting frame. When the telescopic cylinder is activated, the telescopic cylinder pushes the lifting frame to move up and down, thereby driving the cutting head to move up and down.
[0008] As a further technical solution of this utility model, two sliding rods are fixed on both sides of the upper end of the lifting frame, and the sliding rods are slidably connected to the upper end of the frame. The frame limits the sliding rods through the corresponding sliding grooves, which is conducive to the stable lifting of the lifting frame.
[0009] As a further technical solution of this utility model, a guide rail is provided on one side of the positioning frame, and the guide rail is slidably connected to the guide block. The positioning frame limits the guide block through the guide rail, which is conducive to the stable lifting and lowering of the threaded seat.
[0010] As a further technical solution of this utility model, the lower end of the clamp is fixed with an anti-slip cutting board strip, and glass is provided between the anti-slip cutting board strip. The anti-slip cutting board strip is made of a special anti-slip material, which can effectively prevent the glass from sliding during the cutting process and ensure the stability of the cutting.
[0011] As a further technical solution of this utility model, an electric push rod is fixed in the middle of the lower end of the frame, and an anti-slip support plate is fixed at the upper end of the electric push rod. The electric push rod extends and retracts, driving the anti-slip support plate to rise and fall, which is beneficial for supporting the lower end of the glass and effectively preventing the glass from shaking or shifting due to uneven force during cutting.
[0012] As a further technical solution of this utility model, both sides of the lower end of the anti-slip support plate are fixed with sliding rods, and the sliding rods are slidably connected to the lower end of the frame. The frame limits the sliding rods through corresponding sliding grooves, which is conducive to the stable lifting and lowering of the anti-slip support plate.
[0013] Compared with the prior art, the beneficial effects of this utility model are:
[0014] The electric guide rail is set longitudinally. When activated, the sliding frame moves back and forth, causing the cutting head to move back and forth as well. Motor two is activated, the screw rotates, and the threaded seat two moves along the screw, driving the cutting head left and right via the electric guide rail. This expands the cutting range for the glass. Subsequently, the glass moves vertically downwards continuously and stably from the furnace outlet (speed 0.5 m / min to 5 m / min). When the glass reaches the predetermined position, a sensor triggers the robotic arm. The arm uses a vacuum suction device to suction the glass and moves downwards synchronously, pushing the glass between the clamping plates. When the telescopic cylinder is activated, it pushes the lifting frame to move up and down, which in turn moves the cutting head up and down. Motor 1 is started, and the double-sided lead screw rotates, causing the threaded seat 1 to move along the double-sided lead screw. Since the threads at the upper and lower ends of the double-sided lead screw are opposite, the two threaded seats 1 move closer or further apart, causing the clamping plates to move. The two clamping plates cooperate with each other to clamp and release the glass. The electric push rod extends and retracts, causing the anti-slip support plate to rise and fall, which helps to support the lower end of the glass and effectively prevents the glass from shaking or shifting due to uneven force during cutting, resulting in a good cutting effect.
[0015] The anti-slip cutting board strips are made of a special anti-slip material, which can effectively prevent the glass from slipping during the cutting process and ensure the stability of the cutting. Subsequently, the dust collection hood is connected to the dust collection box through a connecting pipe. During the cutting process, the glass fragments and dust generated will be effectively collected by the dust collection hood, which has excellent performance. Attached Figure Description

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0022] Please see Figure 1-4 This utility model provides an embodiment of a precision cutting device for semi-finished glass substrates, comprising a lifting frame 21 and a frame 17. The lifting frame 21 is disposed at the upper end of the frame 17. A screw 15 is rotatably connected between the two ends inside the lifting frame 21, and a threaded seat 20 is threaded onto the screw 15. A motor 16 is fixed to one end of the lifting frame 21, and the output end of the motor 16 is fixedly connected to the driving end of the screw 15. An electric guide rail frame 14 is fixed to the lower end of the threaded seat 20. A sliding frame 13 is provided at the lower end of the rail frame 14. A cutting head 12 is fixed at the lower end of the sliding frame 13. Positioning frames 5 are fixed on both sides of the lower end of the frame body 17. A two-way screw 4 is rotatably connected between the upper end of the positioning frame 5 and the lower end of the frame body 17. A motor 6 is fixed at the upper end of the positioning frame 5. The output end of the motor 6 is fixedly connected to the drive end of the two-way screw 4. A threaded seat 7 is threaded at both the upper and lower ends of the two-way screw 4. A guide block 23 and a clamping plate 3 are fixed at both ends of the threaded seat 7, respectively.
[0023] Specifically, such as Figure 1 and Figure 2 As shown, the electric guide rail frame 14 is longitudinally arranged. When the electric guide rail frame 14 is started, the sliding frame 13 moves back and forth, driving the cutting head 12 to move back and forth. When the second motor 16 is started, the screw 15 rotates, and the second threaded seat 20 moves along the screw 15. Through the electric guide rail frame 14, the cutting head 12 moves left and right, thereby expanding the cutting range of the glass 9. Subsequently, the glass 9 moves vertically downwards continuously and stably from the furnace outlet (speed 0.5m / min to 5m / min). When the glass 9 descends to the predetermined position, the sensor triggers the robot arm. The arm adsorbs the glass 9 through the vacuum adsorption device and moves downwards synchronously, pushing the glass 9 between the clamping plates 3. At the same time, the first motor 6 is started, and the bidirectional lead screw 4 rotates, driving the first threaded seat 7 to move along the bidirectional lead screw 4. Since the threads at the upper and lower ends of the bidirectional lead screw 4 are opposite, the two threaded seats 7 move closer or further apart, driving the clamping plates 3 to move. The two clamping plates 3 cooperate with each other to clamp and release the glass 9.
[0024] A fixed base 22 is fixed on one side of the sliding frame 13, and a dust collection hood 11 is provided in the middle of the fixed base 22;
[0025] Specifically, such as Figure 1 and Figure 4 As shown, the dust collection hood 11 is connected to the dust collection box through a connecting pipe. During the cutting process, the glass shards and dust generated will be effectively collected by the dust collection hood 11.
[0026] A telescopic cylinder 19 is fixed in the middle of the upper end of the frame 17, and the lower end of the telescopic cylinder 19 is fixedly connected to the upper end of the lifting frame 21.
[0027] Specifically, such as Figure 1 and Figure 2 As shown, when the telescopic cylinder 19 is activated, the telescopic cylinder 19 pushes the lifting frame 21 to move up and down, which in turn drives the cutting head 12 to move up and down.
[0028] Both sides of the upper end of the lifting frame 21 are fixed with sliding rods 18, and the sliding rods 18 are slidably connected to the upper end of the frame 17.
[0029] Specifically, such as Figure 1 and Figure 4 As shown, the frame 17 limits the sliding rod 18 through the corresponding sliding groove, which is beneficial to the stable lifting of the lifting frame 21.
[0030] A guide rail 24 is provided on one side of the positioning frame 5, and the guide rail 24 is slidably connected to the guide block 23;
[0031] Specifically, such as Figure 1 and Figure 3 As shown, the positioning frame 5 limits the guide block 23 through the guide rail 24, which is conducive to the stable lifting and lowering of the threaded seat 7.
[0032] The lower end of the clamping plate 3 is fixed with anti-slip cutting board strips 8, and glass 9 is provided between the anti-slip cutting board strips 8;
[0033] Specifically, such as Figure 1 and Figure 3 As shown, the anti-slip cutting board strip 8 is made of a special anti-slip material, which can effectively prevent the glass 9 from sliding during the cutting process and ensure the stability of the cutting.
[0034] An electric push rod 1 is fixed in the middle of the lower end of the frame 17, and an anti-slip support plate 10 is fixed at the upper end of the electric push rod 1.
[0035] Specifically, such as Figure 1 and Figure 2 As shown, the electric push rod 1 extends and retracts, driving the anti-slip support plate 10 to rise and fall, which helps to support the lower end of the glass 9 and effectively prevents the glass 9 from shaking or shifting due to uneven force during cutting.
[0036] Both sides of the lower end of the anti-slip support plate 10 are fixed with sliding rods 2, and the sliding rods 2 are slidably connected to the lower end of the frame 17.
[0037] Specifically, such as Figure 1and Figure 2 As shown, the frame 17 limits the sliding rod 2 through the corresponding sliding groove, which is conducive to the stable lifting and lowering of the anti-slip support plate 10.
[0038] Working principle: In use, the electric guide rail frame 14 is set longitudinally. When the electric guide rail frame 14 is started, the sliding frame 13 moves back and forth, driving the cutting head 12 to move back and forth. When the second motor 16 is started, the screw 15 rotates, and the second thread seat 20 moves along the screw 15. Through the electric guide rail frame 14, the cutting head 12 moves left and right, thereby expanding the cutting range of the glass 9. Subsequently, the glass 9 moves vertically downwards continuously and stably from the furnace outlet (speed 0.5m / min to 5m / min). When the glass 9 descends to the predetermined position, the sensor triggers the robot arm. The arm uses a vacuum adsorption device to adsorb the glass 9 and moves downwards synchronously, pushing the glass 9 between the clamping plates 3. At the same time, the telescopic cylinder 19 is started, pushing the lifting frame 21 up and down, which in turn drives the cutting head 12 to move up and down. When the first motor 6 is started, the bidirectional lead screw 4 rotates, driving the first thread seat 7 to move along the bidirectional lead screw 4. Since the threads at the upper and lower ends of the bidirectional lead screw 4 are opposite, the two threads... The two clamping plates 3 move together, moving closer or further apart, which in turn moves the clamping plates 3. These two clamping plates 3 work together to clamp and release the glass 9. The electric push rod 1 extends and retracts, causing the anti-slip support plate 10 to rise and fall, effectively supporting the lower end of the glass 9 and preventing it from shaking or shifting due to uneven force during cutting. The anti-slip cutting board strip 8 is made of a special anti-slip material, effectively preventing the glass 9 from slipping during cutting and ensuring cutting stability. The dust collection cover 11... Connected to the dust collection box via a connecting pipe, the glass shards and dust generated during the cutting process are effectively collected by the dust collection hood 11. Furthermore, the frame 17 limits the sliding rod 28 via a corresponding sliding groove, which facilitates the stable lifting of the lifting frame 21. The frame 17 also limits the sliding rod 12 via a corresponding sliding groove, which facilitates the stable lifting of the anti-slip support plate 10. The positioning frame 5 limits the guide block 23 via the guide rail 24, which facilitates the stable lifting of the threaded seat 17. In summary, this equipment has good cutting effect and excellent performance.
