Description

Technical Field

[0001] The present invention relates to the technical field of glass substrate processing equipment, and particularly relates to a cutting buffer device for liquid crystal glass substrates. Background Art

[0002] The cutting of liquid crystal glass substrates is a high-precision process widely used in the manufacture of liquid crystal displays. The cutting of liquid crystal glass substrates cuts large-sized liquid crystal glass substrates into required small sizes to meet the processing requirements of subsequent products.

[0003] During the cutting process of liquid crystal glass substrates, in order to improve the cutting accuracy of liquid crystal glass substrates, 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 of liquid crystal glass substrates. Currently, the common method for buffering during the cutting process of liquid crystal glass substrates is to fixedly install a rubber pad on the top of the cutting workbench. When cutting the liquid crystal glass substrate, the liquid crystal glass substrate is placed on the rubber pad. After positioning the liquid crystal glass substrate, during the cutting process of the liquid crystal glass substrate by the cutting equipment, when the liquid crystal glass substrate generates resonance, it is transmitted to the rubber pad, and the rubber pad absorbs and processes the vibration force generated during cutting to achieve the buffering purpose. Although this method can buffer during the cutting of liquid crystal glass substrates, in actual use, there are still the following defects:

[0004] Using only a rubber pad for buffering the cutting of liquid crystal glass substrates has a simple structure, but the rubber pad has limited inhibitory effect on high-frequency vibration, resulting in small vibrations during the cutting process, thereby reducing the cutting quality.

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

[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. Apparently, the described embodiments are some but not all of the embodiments of the present invention. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts shall fall within the protection scope of the present invention.

[0041] Embodiment 1

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

[0043] Combined with Figures 1 - 9 As shown, a cutting buffer device for a liquid crystal glass substrate provided by the present invention includes:

[0044] A bottom plate 1, which is installed on a cutting frame 8. The cutting frame 8 includes a base 81 and a frame body 82 installed on the top of the base 81. A moving frame 821 is slidably installed on the top of the frame body 82 along its length direction. A sliding seat 822 is slidably installed on the moving frame 821 along the width direction of the frame body 82. A cutting knife 823 is fixedly installed at the bottom of the sliding seat 822. The bottom plate 1 is installed on the top of the frame body 82 and inside the moving frame 821;

[0045] A mounting plate 2, which is fixedly installed on the top of the bottom plate 1;

[0046] The guiding members 21, with a quantity of four groups, are arranged in a rectangular array on the top of the mounting plate 2. A connecting plate 3 is connected to the tops of the four guiding members 21 and is located below the cutting blade 823.

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

[0048] The rubber pad 31 is fixedly installed on the top of the connecting plate 3. The glass substrate body 32 is placed on the top of the rubber pad 31. Among them, in this embodiment, an installation groove extending to the outside of one end is opened at the top of the frame body 82. The bottom plate 1 is installed in the installation groove to reduce the height after the connecting plate 3 is installed, thereby facilitating the loading and unloading operation of the glass substrate body 32 by the staff.

[0049] The positioning mechanisms 5, with a quantity of two groups, are respectively installed on both sides of the connecting plate 3. Through the two positioning mechanisms 5, the glass substrate body 32 placed on the top of the rubber pad 31 is positioned.

[0050] When cutting the glass substrate body 32, the glass substrate body 32 is placed on the top of the rubber pad 31. The two positioning mechanisms 5 are used to position the glass substrate body 32 placed on the top of the rubber pad 31. At this time, the cutting blade 823 is brought into contact with the glass substrate body 32, and the cutting blade 823 is driven to displace through the moving frame 821 and the sliding seat 822, so as to drive the realization of the cutting effect on the glass substrate body 32. Specifically, it should be noted that: bringing the cutting blade 823 into contact with the glass substrate body 32 and driving the cutting blade 823 to displace through the moving frame 821 and the sliding seat 822 to cut the glass substrate body 32 is the prior art and belongs to the well-known technical scope of those skilled in the art, so it will not be elaborated here; through the design of the buffer assembly 4, when cutting the glass substrate body 32, the rubber pad 31 absorbs part of the vibration force generated during cutting. When part of the vibration force is transmitted to the connecting plate 3 to cause it to resonate, the buffer assembly 4 buffers the connecting plate 3, thereby buffering the resonance acting force of the connecting plate 3, further improving the buffering of the vibration force generated during the cutting of the glass substrate body 32, further improving the suppression effect of the vibration during the cutting process, and thus improving the cutting quality.

[0051] In this embodiment, the guiding member 21 includes a guiding shell 211 fixedly installed on the top of the mounting plate 2 in the vertical direction. A guiding rod 212 fixedly connected to the bottom of the connecting plate 3 vertically penetrates through the top of the guiding shell 211. When in use, when cutting the glass substrate body 32, when the connecting plate 3 is pressed downward by force, the plurality of guiding rods 212 respectively slide into the guiding shell 211 along the plurality of guiding shells 211, so as to realize the guiding effect on the connecting plate 3.

[0052] In this embodiment, the buffer assembly 4 includes a fixing plate 41 fixedly mounted on one end of the mounting plate 2, a vent pipe 42 fixedly mounted on the fixing plate 41, an air bag 43 fixedly mounted on the top of the mounting plate 2 and located inside the four guide shells 211 and fixedly mounted to the connecting plate 3, one end of the vent pipe 42 is connected to the air bag 43, and the other end is fixedly connected to the connecting pipe 45, an electromagnetic valve 44 is mounted on the vent pipe 42, a shell 46 is fixedly mounted on the base 81, and an exhaust valve 45 connected to the inside of the shell 46 is fixedly mounted on one end of the shell 46. The air pipe 47 and the shell 46 are fixedly installed with a negative pressure pump 471 connected to the end of the exhaust pipe 47. The other end of the connecting pipe 45 is connected to the shell 46. The fixed plate 41 is fixedly installed with an air supply pump 48. The end of the ventilation pipe 42 and the electromagnetic valve 1 44 away from the connecting pipe 45 is connected with an intake pipe 49. The other end of the intake pipe 49 is connected to the air supply pump 48. The intake pipe 49 is installed with an electromagnetic valve 2 491. When in use, the electromagnetic valve 2 491 is controlled to be opened, the electromagnetic valve 1 44 is closed, and the air supply pump 48 is controlled. The gas is delivered into the air inlet pipe 49, and then the air bag 43 is inflated through the vent pipe 42. The air bag 43 expands and contacts the connecting plate 3 and the mounting plate 2. When the glass substrate body 32 is cut, the rubber pad 31 absorbs part of the vibration force generated during cutting. When part of the vibration force is transmitted to the connecting plate 3 to resonate, it is transmitted to the air bag 43. When the gas in the air bag 43 is acted upon by an external force, it will be compressed to absorb the impact energy, thereby achieving a buffering effect on the resonance force of the connecting plate 3. 71, when in use, the solenoid valve 2 491 is controlled to be closed, the solenoid valve 1 44 is opened, the negative pressure pump 471 is controlled to work, and the air in the shell 46 is pumped out through the exhaust pipe 47, so that the gas in the airbag 43 is pumped into the shell 46 through the ventilation pipe 42 and the connecting pipe 45, and the amount of gas in the airbag 43 is reduced, thereby lowering the height of the connecting plate 3, which is convenient for loading the glass substrate body 32. It is worth noting that: when it is not necessary to inflate or exhaust the air in the airbag 43, the solenoid valve 2 491 and the solenoid valve 1 44 are controlled to be closed.

[0053] Embodiment 2

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

[0055] In this embodiment, the positioning mechanism 5 includes a mounting base 51 fixedly installed on one side of the connecting plate 3. On the side of the mounting base 51 close to the connecting plate 3, two horizontally arranged driving rods 52 are symmetrically fixed. At the ends of the two driving rods 52 and above the glass substrate body 32, a connecting block 53 is fixedly installed. At the bottom of the connecting block 53, a positioning plate 54 that fits against the top of the rubber pad 31 is fixedly installed. One side of the positioning plate 54 away from the mounting base 51 extends to the outside of the positioning plate 54. Specifically, it should be noted that when the connecting block 53 slides close to the mounting block 513 through the two driving rods 52, the connecting block 53 can be displaced to the outside of the connecting plate 3. During use, after the glass substrate body 32 is placed on the rubber pad 31, the two driving rods 52 on the two groups of positioning mechanisms 5 are controlled to work simultaneously, so that the connecting blocks 53 of the two groups of positioning mechanisms 5 approach each other, thereby driving the two positioning plates 54 to approach each other. When both positioning plates 54 are in contact with the glass substrate body 32, the positioning effect on 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 installed on one side of the connecting plate 3. On the top of the support plate 511, two vertically arranged telescopic rods 512 are symmetrically fixed. The tops of the two telescopic rods 512 are fixedly connected to a mounting block 513. A driving rod 514 fixedly connected to the mounting block 513 is fixedly installed on the top of the support plate 511. The two driving rods 52 are both fixedly installed on the mounting block 513. Through the special design of the mounting base 51 including the support plate 511, the telescopic rods 512, the mounting block 513, and the driving rod 514, after the cutting process of the glass substrate body 32 is completed, the two driving rods 52 on one group of positioning mechanisms 5 are controlled to make the connecting block 53 slide towards the mounting block 513 to the outside of the connecting plate 3, and then the mounting block 513 is displaced downward along the two telescopic rods 512 through the driving rod 514, so that the connecting block 53 is displaced to below the connecting plate 3. At this time, the two driving rods 52 on the other group of positioning mechanisms 5 are controlled to make the connecting block 53 displace away from the mounting block 513, driving the positioning plate 54 to displace, thereby pushing the cut glass substrate body 32 on the rubber pad 31 towards one side of the rubber pad 31, which is beneficial for discharging the cut glass substrate body 32 placed on the top of the rubber pad 31.

[0057] In this embodiment, intake cavities 531 are formed on the sides of the two connection blocks 53 that are close to each other. At one end of the connection block 53 close to the fixed plate 41, an air outlet pipe 532 is fixedly installed and communicates with the inside of the intake cavity 531. A connecting pipe 411 is fixedly installed on the fixed plate 41. One end of the connecting pipe 411 is connected in a penetrating manner to the ventilation pipe 42 on the side of the first electromagnetic valve 44 close to the connecting pipe 45, and the other end is fixedly connected to two air guide pipes 412 that communicate with its inside. The other ends of the two air guide pipes 412 are fixedly connected to the two air outlet pipes 532 respectively. A third electromagnetic valve 413 is installed on the connecting pipe 411. Through the special design of forming the intake cavity 531 on the connection block 53, when cutting the glass substrate body 32, the third electromagnetic valve 413 is controlled to open, and the negative pressure pump 471 is controlled to work to pump the gas in the housing 46 outwards. A negative pressure is formed in the housing 46. The gas in the intake cavities 531 on the two connection blocks 53 is pumped out through the connecting pipe 45, the connecting pipe 411, the two air guide pipes 412, and the two air outlet pipes 532. Thus, the air between the two connection blocks 53 is pumped into the two intake cavities 531, and then the powder generated during the cutting process of the glass substrate body 32 can be sucked into the two intake cavities 531 and then into the housing 46, achieving the effect of absorbing the powder generated during the cutting process of the glass substrate body 32.

[0058] Embodiment Three

[0059] As Figures 1 - 9 shown, on the basis of the above embodiment, the following content is further given in this embodiment:

[0060] In this embodiment, a communication port 461 communicating with its interior is provided on one side of the housing 46. A sealing plate 462 for blocking the communication port 461 is hinged on the housing 46. The sealing plate 462 and the housing 46 are fixed by a buckle. A filter element 6 is installed on the inner side wall of the housing 46 and outside the exhaust pipe 47, which 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 blocks the communication port 461, the sealing gasket 463 abuts against the housing 46. By providing the filter element 6, when the negative pressure pump 471 works to pump the gas in the housing 46 outwards, the filter element 6 filters the gas discharged from the housing 46 outwards, so as to realize the filtration of the powder inhaled into the housing 46, so that the powder remains in the housing 46, and the collection effect of the powder generated during the cutting of the glass substrate body 32 is realized. When it is necessary to clean the powder collected in the housing 46, cancel the fixation of the buckle between the sealing plate 462 and the housing 46, and the sealing plate 462 can be rotated on the housing 46 to cancel the blocking of the communication port 461, which is convenient for cleaning the powder collected in the housing 46; through the design of the sealing gasket 463, when the sealing plate 462 blocks the communication port 461, the sealing gasket 463 abuts against the housing 46, increasing the adhesion between the sealing plate 462 and the housing 46, thereby increasing the blocking effect on the communication port 461.

[0061] In this embodiment, the filter element 6 includes a communication shell 61 fixedly installed on the inner side wall of the housing 46 and outside the exhaust pipe 47. The communication shell 61 is communicated with the exhaust pipe 47. A slot 62 is provided on one side of the communication shell 61 close to the communication port 461. A filter plate 63 for blocking the interior of the communication shell 61 is inserted into the slot 62 on the communication shell 61. During use, when the negative pressure pump 471 works to pump the gas in the housing 46 outwards, when the powder contacts the filter plate 63 along with the air flow, 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 inserted into the slot 62 and blocking the interior of the communication shell 61, it is convenient to disassemble the filter plate 63, so as to facilitate the cleaning or replacement of the filter plate 63;

[0062] A collection box 9 with an open top is placed on the inner bottom wall of the housing 46 and below the communication shell 61. By providing the collection box 9, after the filter plate 63 filters the powder, the powder remaining in the housing 46 falls into the collection box 9 under the action of its own gravity, realizing the collection effect of the powder, and further facilitating the cleaning of the powder collected in the housing 46.

[0063] In this embodiment, the bottom plate 1 is slidably mounted on the top of the frame body 82 along the length direction of the frame body 82. A driving mechanism 7 acting on the bottom plate 1 is installed on the frame body 82, which is used to make the bottom plate 1 slide or stop sliding on the frame body 82. The connecting pipe 45 adopts a corrugated hose. By setting the bottom plate 1 to be slidably mounted on the top of the frame body 82 along the length direction of the frame body 82, during use, the driving mechanism 7 is used to make the bottom plate 1 slide on the frame body 82, thereby driving the bottom plate 1 to displace outward from the frame body 82, driving the buffer assembly 4 and the positioning mechanism 5 to displace outward from the frame body 82, so as to facilitate the later maintenance and repair of the buffer assembly 4 and the positioning mechanism 5.

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

[0065] It should be noted that in this article, relational terms such as first and second are only used to distinguish one entity or operation from another entity or operation, and do not necessarily require or imply any actual relationship or order between these entities or operations. Moreover, the terms "include", "comprise" or any other variant thereof are intended to cover non-exclusive inclusion, so that a process, method, article or device including a series of elements not only includes those elements, but also includes other elements not expressly listed, or also includes elements inherent to such process, method, article or device.
