Description

Technical Field

[0001] The present invention relates to the field of display screen production devices, and particularly to a cutting device for processing display screen glass. Background Art

[0002] Liquid crystal displays belong to one type of flat panel displays and are used for screen displays of televisions, computers, etc. The advantages of such displays are low power consumption, small size, and low radiation, so they are widely used. There are also more and more processing devices配套 with liquid crystal display production. One of the key processing devices is the liquid crystal display cutting device, which cuts a large piece of screen substrate into several small liquid crystal screens of preset sizes. Patent Application No.: CN202020965128.2 discloses a laser cutting control device for LCD liquid crystal displays, including a cutting box, a cover, and a cleaning box. On both sides inside the cutting box, there are first slides, and the first slides are connected to a second slide through first sliders. At the same time, the second slide is arranged inside the cutting box. The second slide is connected to a laser cutting beam through a second slider, and the laser cutting beam is arranged below the outside of the second slider. Such a device cuts glass through a single laser cutting beam. When it is necessary to cut a large screen into multiple small-sized liquid crystal screens, multiple cuts are required to achieve this, resulting in low cutting efficiency.

[0003] The present invention is studied and proposed in view of the deficiencies of the prior art. Summary of the Invention

[0004] The object of the present invention is to overcome the above-mentioned deficiencies of the prior art and provide a cutting device for processing display screen glass.

[0005] The present invention can be realized through the following technical solutions:

[0006] This invention discloses a cutting device for processing display screen glass, comprising a base plate, on which a slide rail and a screw are mounted. The screw is driven to rotate by a cutting motor. A slider is mounted on the slide rail and slidably connected to it. A threaded tube is mounted on the screw and threadedly connected to it. Fixing plates are fixed to both the threaded tube and the slider. A support rod is fixed between two fixing plates. Multiple fixing blocks are mounted on the support rod. A cutting blade is mounted on the bottom of each fixing block. A push rod is mounted on one side of the support rod. A positioning block is mounted on the push rod between two fixing blocks. The push rod passes through and slidably connects to the positioning block. Each of the positioning blocks is connected to a corresponding fixed block via a connecting device. The connecting device includes a limiting shaft fixed on the fixed block and a positioning shaft fixed on the positioning block. The positioning shaft is connected to the corresponding limiting shaft via a connecting rod. One end of the connecting rod is rotatably connected to the positioning shaft, and the other end of the connecting rod is rotatably connected to the limiting shaft. Push plates are fixed at both ends of the push rod. Positioning motors are fixed on both of the fixed plates. A lead screw is fixed at the output end of each positioning motor. The lead screw passes through the corresponding push plate and is threadedly connected to the push plate. A rotary motor is also fixed on the base plate, and a support plate is fixed at the output end of the rotary motor. The display glass to be cut is placed on the support plate. A cutting motor drives the screw to rotate. As the screw rotates, the threaded tube moves in the screw direction, and the cutting blades move from one side of the glass to the other, slicing the glass horizontally. After the glass is horizontally sliced, a rotary motor drives the support plate to rotate 90 degrees, and two positioning motors drive the lead screw to rotate. Because the lead screw is threadedly connected to the push plate, the push plate moves in the screw direction as the lead screw rotates. The distance between the push rod and the support rod is adjusted. When the push rod moves to the designated position, the distance between two adjacent fixed blocks is adjusted to... Once the appropriate position is achieved, the distance between two adjacent cutting blades can be adjusted. After the cutting blades are adjusted to the designated position, the screw is driven to rotate again by the cutting motor, and the cutting blades move from one end of the screen glass to the other end to perform a longitudinal cut on the screen glass, cutting the glass into multiple small pieces. This device uses multiple cutting blades to cut the glass laterally. After the glass is cut laterally, it is rotated 90 degrees. Then, by adjusting the position of each cutting blade, the glass is cut longitudinally again by each cutting blade, thus cutting a large piece of glass into multiple small pieces, greatly improving the glass cutting efficiency.

[0007] Preferably, one of the fixing blocks is fixed to the support rod.

[0008] Preferably, a limiting tube is fixed to the bottom of the fixing block, the cutting blade is fixed to the limiting rod, the top of the limiting rod is disposed inside the limiting tube and slidably connected to the limiting tube, and a spring is also fixed inside the limiting tube above the limiting rod. The spring pushes the limiting rod to prevent the cutting blade from colliding with the glass and causing the glass to break.

[0009] Preferably, a sliding rod is also fixed on the fixing plate, the sliding rod passing through the push plate at the corresponding position and slidably connected to the push plate.

[0010] Preferably, the support plate is further provided with a cavity, which is connected to a vacuum pump via an air pipe. The support plate is also evenly provided with multiple air holes communicating with the cavity. During glass cutting, the vacuum pump draws air into the air holes, creating a negative pressure at the air hole locations, thus fixing the glass to the support plate.

[0011] Compared with existing technologies, the present invention has the following advantages:

[0012] This device can perform pressure holding operations on the screen. After the pressure ring contacts the screen, the pressure plate is fixed to hold the screen under pressure. Moreover, this device can perform pressure holding operations on multiple screens at the same time, which greatly improves the screen production efficiency. Attached Figure Description

[0017] The embodiments of the present invention will now be described in detail with reference to the accompanying drawings:

[0018] Example 1:

[0019] like Figures 1 to 2As shown, this embodiment discloses a cutting device for processing display screen glass, comprising a base plate 1, on which a slide rail 2 and a screw 4 are provided. The screw 4 is driven to rotate by a cutting motor 5. A slider 3 is provided on the slide rail 2 and slidably connected to the slide rail 2. A threaded tube 6 is provided on the screw 4 and threadedly connected to the screw 4. Fixing plates 7 are fixed on both the threaded tube 6 and the slider 3. A support rod 8 is fixed between the two fixing plates 7. Multiple fixing blocks 9 are provided on the support rod 8. A cutting blade 12 is provided at the bottom of each fixing block 9. A push rod 17 is provided on one side of the support rod 8. A positioning block 13 is provided on each push rod 17 between the two fixing blocks 9. The push rod 17 passes through the positioning block 13. 3. It is slidably connected to the positioning block 13. The positioning block 13 is connected to the corresponding fixed block 9 through the connecting device. The connecting device includes the limiting shaft 14 fixed on the fixed block 9. The connecting device also includes the positioning shaft 15 fixed on the positioning block 13. The positioning shaft 15 is connected to the corresponding limiting shaft 14 through the connecting rod 16. Push plates 18 are fixed at both ends of the push rod 17. Positioning motors 19 are fixed on both fixed plates 7. Screws 21 are fixed at the output end of the positioning motors 19. The screws 21 pass through the corresponding push plates 18 and are threadedly connected to the push plates 18. A rotary motor 22 is also fixed on the base plate 1. A support plate 23 is fixed at the output end of the rotary motor 22. The display glass to be cut is placed on the support plate 23. The screw 4 is driven to rotate by the cutting motor 5. When the screw 4 rotates, the threaded tube 6 moves in the direction of the screw 4. The cutting blades 12 move from one side of the glass to the other side, and the glass is cut by the cutting blades 12. After the glass is cut laterally, the rotary motor 22 drives the support plate 23 to rotate 90 degrees, and the lead screw 21 is driven to rotate by the two positioning motors 19. Since the lead screw 21 is threadedly connected to the push plate 18, the push plate 18 moves in the direction of the lead screw 21 when the lead screw 21 rotates. The distance between the push rod 17 and the support rod 8 is adjusted. When the push rod 17 moves, after the push rod 17 moves to the designated position, the adjacent two pieces After the distance between the fixed blocks 9 is adjusted to a suitable position, the distance between two adjacent cutting blades 12 can be adjusted. When the cutting blades 12 are adjusted to the designated position, the screw 4 is driven to rotate again by the cutting motor 5. The cutting blades move from one end of the screen glass to the other end to achieve longitudinal cutting of the screen glass, cutting the glass into multiple small pieces. This device cuts the glass laterally with multiple cutting blades 12. After the glass is cut laterally, it is rotated 90 degrees. Then, by adjusting the position of each cutting blade 12, the glass is cut longitudinally again with each cutting blade 12, thus cutting a large piece of glass into multiple small pieces of glass, which greatly improves the glass cutting efficiency.

[0020] One of the fixing blocks 9 is fixed to the support rod 8.

[0021] The fixing block 9 has a limiting tube 10 fixed at its bottom, and the cutting blade 12 is fixed on the limiting rod 11. The top of the limiting rod 11 is located inside the limiting tube 10 and is slidably connected to the limiting tube 10. A spring is also fixed inside the limiting tube 10 above the limiting rod 11. The spring pushes the limiting rod 11 to prevent the cutting blade 12 from colliding with the glass and causing it to break.

[0022] The support plate 23 also has a cavity, which is connected to a vacuum pump via an air pipe. Multiple air holes 24, communicating with the cavity, are also evenly distributed on the support plate 23. During glass cutting, the vacuum pump draws air into the air holes 24, creating a negative pressure that fixes the glass onto the support plate 23.

[0023] Example 2:

[0024] This embodiment discloses a cutting device for processing display screen glass. Based on the structure and principle of embodiment 1, the fixed plate 7 of this embodiment is also fixed with a slide rod 20. The slide rod 20 passes through the push plate 18 at the corresponding position and is slidably connected to the push plate 18.

[0025] The above are merely preferred embodiments of the present invention. It should be noted that, for those skilled in the art, various changes, modifications, substitutions and variations can be made to these embodiments without departing from the technical principles of the present invention. These changes, modifications, substitutions and variations should also be considered within the scope of protection of the present invention.
