Description

Technical Field

[0001] This invention relates to the field of glass substrate processing equipment technology, and specifically to a liquid crystal glass substrate cutting buffer device. Background Technology

[0002] LCD glass substrate cutting is a high-precision process widely used in LCD manufacturing. LCD glass substrate cutting cuts large-sized LCD glass substrates into smaller sizes to meet the needs of subsequent product processing.

[0003] In the process of cutting LCD glass substrates, to improve the cutting accuracy, a buffer mechanism needs to be installed on the cutting equipment to reduce the impact and vibration generated during cutting, thereby reducing the occurrence of substrate breakage and improving the cutting accuracy. Currently, the common method for buffering during LCD glass substrate cutting involves fixing a rubber pad on the top of the cutting table. During cutting, the LCD glass substrate is placed on the rubber pad and positioned. When the LCD glass substrate resonates during cutting, the vibration is transmitted to the rubber pad, which absorbs the vibration, thus achieving the buffering purpose. While this method can buffer the LCD glass substrate during cutting, it still has the following drawbacks in practical use:

[0004] Although using rubber pads for cutting LCD glass substrates is simple in structure, the rubber pads have limited effect on suppressing high-frequency vibrations, which leads to minute vibrations during the cutting process and thus reduces the cutting quality.

[0005] Therefore, this application proposes a liquid crystal glass substrate cutting buffer device. Summary of the Invention

When part of the vibration force is transmitted to the connecting plate and causes it to resonate, the buffer component buffers the connecting plate, thereby buffering the resonant force of the connecting plate, thus further improving the buffering of the vibration force generated during the cutting of the glass substrate, further improving the suppression effect of vibration during the cutting process, and thus improving the cutting quality.

This allows the powder generated during the cutting of the glass substrate to be sucked into the two air intake chambers and then into the housing, achieving the effect of absorbing and treating the powder generated during the cutting of the glass substrate.

[0040] To make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments of the present invention are described clearly and completely. Obviously, the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0041] Example 1

[0042] To address the technical problems in the background art, the following liquid crystal glass substrate cutting buffer device is provided:

[0043] Combination Figures 1-9 As shown, the present invention provides a liquid crystal glass substrate cutting buffer device, comprising:

[0044] The base plate 1 is mounted on the cutting machine frame 8. The cutting machine frame 8 includes a base 81 and a frame 82 mounted on the top of the base 81. A movable frame 821 is slidably mounted on the top of the frame 82 along its length. A sliding seat 822 is slidably mounted on the movable frame 821 along the width of the frame 82. A cutting blade 823 is fixedly mounted at the bottom of the sliding seat 822. The base plate 1 is mounted on the top of the frame 82 and is located inside the movable frame 821.

[0045] Mounting plate 2 is fixedly installed on the top of base plate 1;

[0046] There are four sets of guide components 21 arranged in a rectangular array on the top of the mounting plate 2. A connecting plate 3 is connected to the top of the four sets of guide components 21 and below the cutting blade 823.

[0047] The buffer assembly 4 is installed on top of the mounting plate 2 and located between the four sets of guide members 21. The buffer assembly 4 is used to buffer the vibration force of the connecting plate 3.

[0048] A rubber pad 31 is fixedly installed on the top of the connecting plate 3. A glass substrate body 32 is placed on the top of the rubber pad 31. In this embodiment, the top of the frame 82 is provided with a mounting groove extending to the outer side of one end. The bottom plate 1 is installed in the mounting groove to reduce the height of the connecting plate 3 after installation, thereby facilitating the loading and unloading of the glass substrate body 32 by the workers.

[0049] The positioning mechanism 5 consists of two sets, which are respectively installed on both sides of the connecting plate 3. The two sets of positioning mechanisms 5 are used to position the glass substrate body 32 placed on top of the rubber pad 31.

[0050] When cutting the glass substrate body 32, the glass substrate body 32 is placed on top of the rubber pad 31. Two sets of positioning mechanisms 5 position the glass substrate body 32 on top of the rubber pad 31. At this time, the cutting blade 823 contacts the glass substrate body 32, and the moving frame 821 and sliding seat 822 move the cutting blade 823, thus achieving the cutting effect on the glass substrate body 32. Specifically, the cutting blade 823 contacts the glass substrate body 32, and the moving frame 821 and sliding seat 822 move the cutting blade 823 to cut the glass substrate body 32. Cutting the glass substrate body 32 is an existing technology and is well known to those skilled in the art, so it will not be described in detail here. Through the design of the buffer component 4, when the glass substrate body 32 is cut, the rubber pad 31 absorbs part of the vibration force generated during the cutting. When part of the vibration force is transmitted to the connecting plate 3 and causes it to resonate, the buffer component 4 buffers the connecting plate 3, thereby buffering the resonance force of the connecting plate 3, thereby further improving the buffering of the vibration force generated during the cutting of the glass substrate body 32, further improving the suppression effect of vibration during the cutting process, and thus improving the cutting quality.

[0051] In this embodiment, the guide member 21 includes a guide shell 211 that is vertically oriented and fixedly installed on the top of the mounting plate 2. The top of the guide shell 211 is vertically movably oriented with a guide rod 212 that is fixedly connected to the bottom of the connecting plate 3. In use, when the glass substrate body 32 is cut, when the connecting plate 3 is pressed down by force, the multiple guide rods 212 slide along the multiple guide shells 211 into the guide shells 211 respectively, thereby achieving the guiding effect on the connecting plate 3.

[0052] In this embodiment, the buffer assembly 4 includes a fixed plate 41 fixedly installed at one end of the mounting plate 2, a vent pipe 42 fixedly installed on the fixed plate 41, an airbag 43 fixedly installed on the top of the mounting plate 2 and inside the four guide shells 211, which is fixedly connected to the connecting plate 3, one end of the vent pipe 42 is connected to the airbag 43 through the airbag 43, and the other end is fixedly connected to a connecting pipe 45, a solenoid valve 44 is installed on the vent pipe 42, and a housing 46 is fixedly installed on the base 81, with a drain valve communicating with its interior fixedly installed at one end of the housing 46. A negative pressure pump 471, connected to the end of the exhaust pipe 47, is fixedly installed on the housing 46. The other end of the connecting pipe 45 is connected to the housing 46. An air supply pump 48 is fixedly installed on the fixing plate 41. An air inlet pipe 49 is connected to the end of the air pipe 42, located away from the connecting pipe 45 and connected to the solenoid valve 44. The other end of the air inlet pipe 49 is connected to the air supply pump 48. A solenoid valve 491 is installed on the air inlet pipe 49. In use, the solenoid valve 491 is opened and the solenoid valve 44 is closed, thus controlling the air supply pump 48. Gas is supplied to the intake pipe 49, thereby inflating the airbag 43 through the vent pipe 42. The inflated airbag 43 contacts both the connecting plate 3 and the mounting plate 2. During the cutting of the glass substrate body 32, the rubber pad 31 absorbs some of the vibration force generated during cutting. Some of the vibration force is transmitted to the connecting plate 3, causing it to resonate, and then transmitted to the airbag 43. When the gas inside the airbag 43 is subjected to external force, it is compressed, absorbing the impact energy, thus achieving a buffering effect against the resonant force of the connecting plate 3. The negative pressure pump 4... In the design of 71, during use, the control solenoid valve 491 is closed and the control solenoid valve 44 is opened, controlling the negative pressure pump 471 to work, drawing the air in the housing 46 out through the exhaust pipe 47, thereby drawing the gas in the airbag 43 into the housing 46 through the vent pipe 42 and the connecting pipe 45. The amount of gas in the airbag 43 is reduced, thereby lowering the height of the connecting plate 3, which facilitates the feeding of the glass substrate body 32. It is worth noting that when it is not necessary to inflate or de-inflate the airbag 43, the control solenoid valve 491 and the control solenoid valve 44 are closed.

[0053] Example 2

[0054] like Figures 1-9 As shown, based on the above embodiments, this embodiment further provides the following:

[0055] In this embodiment, the positioning mechanism 5 includes a mounting base 51 fixedly installed on one side of the connecting plate 3. A horizontally oriented drive rod 52 is symmetrically fixed on the side of the mounting base 51 near the connecting plate 3. A connecting block 53 is fixedly installed at the ends of the two drive rods 52 above the glass substrate body 32. A positioning plate 54, which is in contact with the top of the rubber pad 31, is fixedly installed at the bottom of the connecting block 53. The side of the positioning plate 54 away from the mounting base 51 extends to the outside of the positioning plate 54. Specifically, when the connecting block 53 slides closer to the mounting block 513 via the two drive rods 52, the connecting block 53 can be displaced to the outside of the connecting plate 3. In use, after the glass substrate body 32 is placed on the rubber pad 31, the two drive rods 52 on the two sets of positioning mechanisms 5 are simultaneously controlled to work, causing the connecting blocks 53 of the two sets of positioning mechanisms 5 to move closer to each other, thereby driving the two positioning plates 54 to move closer to each other. When both positioning plates 54 are in contact with the glass substrate body 32, the positioning effect of the glass substrate body 32 placed on the rubber pad 31 can be achieved.

[0056] In this embodiment, the mounting base 51 includes a support plate 511 fixedly mounted on one side of the connecting plate 3. Vertical telescopic rods 512 are symmetrically fixed to the top of the support plate 511. Mounting blocks 513 are fixedly connected to the tops of the two telescopic rods 512. A second driving rod 514, which is fixedly connected to the mounting block 513, is fixedly mounted to the top of the support plate 511. Two driving rods 52 are fixedly mounted on the mounting block 513. Through the special design of the mounting base 51, including the support plate 511, telescopic rods 512, mounting block 513, and driving rod 514, after the glass substrate body 32 is cut, one set of positioning mechanisms is controlled. The two drive rods 52 on the 5 cause the connecting block 53 to slide towards the mounting block 513 to the outside of the connecting plate 3. Then, the drive rod 514 causes the mounting block 513 to move downward along the two telescopic rods 512, so that the connecting block 53 is moved to the bottom of the connecting plate 3. At this time, the two drive rods 52 on the other set of positioning mechanisms 5 are controlled to move the connecting block 53 away from the mounting block 513, thereby driving the positioning plate 54 to move. This pushes the glass substrate body 32 cut on the rubber pad 31 to one side of the rubber pad 31, which is beneficial for unloading the glass substrate body 32 cut on the top of the rubber pad 31.

[0057] In this embodiment, each of the two connecting blocks 53 has an air inlet chamber 531 on one side close to each other. An air outlet pipe 532 communicating with the interior of the air inlet chamber 531 is fixedly installed at one end of the connecting block 53 near the fixing plate 41. A connecting pipe 411 is fixedly installed on the fixing plate 41. One end of the connecting pipe 411 is connected through to the air pipe 42 on the side of the solenoid valve 44 near the connecting pipe 45, and the other end is fixedly connected to two air guide pipes 412, both communicating with the interior of the air guide pipe 412. The other ends of the two air guide pipes 412 are respectively fixedly connected to the two air outlet pipes 532. A solenoid valve 413 is installed on the connecting pipe 411. This special design of opening the air inlet chamber 531 on the connecting block 53 achieves this effect. When the glass substrate body 32 is cut, the control solenoid valve 413 is opened, and the negative pressure pump 471 is operated to draw the gas out of the housing 46, forming a negative pressure inside the housing 46. The gas in the air inlet chamber 531 on the two connecting blocks 53 is drawn out through the connecting pipe 45, the connecting pipe 411, the two air guide pipes 412 and the two air outlet pipes 532, thereby drawing the air between the two connecting blocks 53 into the two air inlet chambers 531. This allows the powder generated during the cutting of the glass substrate body 32 to be sucked into the two air inlet chambers 531 and then into the housing 46, achieving the effect of absorbing and treating the powder generated during the cutting of the glass substrate body 32.

[0058] Example 3

[0059] like Figures 1-9 As shown, based on the above embodiments, this embodiment further provides the following:

[0060] In this embodiment, a communication port 461 communicating with the interior is provided on one side of the housing 46. A sealing plate 462 for sealing the communication port 461 is hinged to the housing 46. The sealing plate 462 is fixed to the housing 46 by a fastener. A filter element 6 is installed on the inner wall of the housing 46 and outside the exhaust pipe 47. It is used to filter the gas discharged through the exhaust pipe 47. A sealing gasket 463 is fixedly installed on one side of the sealing plate 462. When the sealing plate 462 seals the communication port 461, the sealing gasket 463 abuts against the housing 46. By setting the filter element 6, when the negative pressure pump 471 works to draw the gas out of the housing 46, the filter element 6 filters the gas discharged out of the housing 46. The filter effectively filters the powder drawn into the housing 46, leaving the powder residue inside. This process collects the powder generated during the cutting of the glass substrate body 32. When cleaning the powder collected in the housing 46 is required, the fasteners securing the sealing plate 462 to the housing 46 are removed, allowing the sealing plate 462 to rotate on the housing 46 and release the blockage of the connection port 461, facilitating the cleaning of the collected powder. The sealing gasket 463, when the sealing plate 462 blocks the connection port 461, forms contact with the housing 46, increasing the fit between the sealing plate 462 and the housing 46, thus enhancing the sealing effect of the connection port 461.

[0061] In this embodiment, the filter element 6 includes a connecting shell 61 fixedly mounted on the inner wall of the housing 46 and located outside the exhaust pipe 47. The connecting shell 61 is connected to the exhaust pipe 47. A slot 62 is provided on the side of the connecting shell 61 near the connecting port 461. A filter plate 63 for sealing the inside of the connecting shell 61 is inserted on the connecting shell 61 and in the slot 62. In use, when the negative pressure pump 471 works to draw the gas out of the housing 46, the powder comes into contact with the filter plate 63 with the airflow, and the powder can be filtered by the filter plate 63, so that the powder remains in the housing 46. By setting the filter plate 63 to be inserted into the slot 62 and sealing the inside of the connecting shell 61, it is easy to disassemble the filter plate 63, thereby facilitating the cleaning or replacement of the filter plate 63.

[0062] A collection box 9 with an open top is placed on the bottom wall of the inner shell 46 and below the communicating shell 61. By setting the collection box 9, after the filter plate 63 filters the powder, the powder remaining in the shell 46 falls into the collection box 9 under its own gravity, thereby achieving the effect of collecting the powder and making it easier to clean the powder collected in the shell 46.

[0063] In this embodiment, the base plate 1 is slidably installed on the top of the frame 82 along the length direction of the frame 82. A drive mechanism 7 acting on the base plate 1 is installed on the frame 82, which is used to make the base plate 1 slide on the frame 82 or stop sliding. The connecting pipe 45 is a corrugated flexible hose. By setting the base plate 1 to slide on the top of the frame 82 along the length direction of the frame 82, in use, the drive mechanism 7 makes the base plate 1 slide on the frame 82, thereby driving the base plate 1 to move outward of the frame 82, driving the buffer assembly 4 and the positioning mechanism 5 to move outward of the frame 82, thereby facilitating the later inspection and maintenance of the buffer assembly 4 and the positioning mechanism 5.

[0064] In this embodiment, the drive mechanism 7 includes a threaded rod 71 that is horizontally rotatably mounted on the frame 82. The threaded rod 71 is threadedly connected to the base plate 1. A motor 72 for driving the threaded rod 71 to rotate is fixedly mounted on the frame 82. In use, the motor 72 is controlled to work, and the output shaft of the motor 72 rotates, causing the threaded rod 71 to rotate on the frame 82. Since the threaded rod 71 is threadedly connected to the base plate 1, the base plate 1 can be driven to slide on the frame 82. Since the threaded connection between the threaded rod 71 and the base plate 1 has self-locking properties, the base plate 1 will not slide naturally on the frame 82 when the motor 72 is not working, which facilitates control.

Furthermore, the terms "comprising," "including," or any other variations thereof are intended to cover non-exclusive inclusion, such that a process, method, article, or apparatus that comprises a list of elements includes not only those elements but also other elements not expressly listed, or elements inherent to such a process, method, article, or apparatus.
