Description

Technical Field

[0001] This utility model belongs to the field of liquid crystal display manufacturing technology, and specifically relates to a liquid crystal display panel cutting fixture. Background Technology

[0002] In the cutting and processing of LCD panels, vacuum adsorption fixtures have become the mainstream workpiece fixing solution in the industry due to their advantages of non-contact fixing and avoiding mechanical clamping stress deformation. In the existing technology, such fixtures usually use a porous vacuum suction cup as the core adsorption component. A vacuum pump generates negative pressure, and the adsorption force is formed through the adsorption holes evenly distributed on the surface of the suction cup to fix the LCD panel on the processing platform.

[0003] When the effective adsorption area of ​​the vacuum suction cup is larger than the size of the LCD panel to be cut, the adsorption holes outside the panel edge are in an "exposed" open state. This phenomenon easily leads to the glass fragments and conductive layer dust generated by the cutting device from the LCD panel being quickly sucked into the adsorption holes under the direct traction of the negative pressure airflow of the suction cup. Since the fragments inside the adsorption holes are difficult to be discharged in time through conventional filtration methods, as the fragments continue to accumulate at the adsorption holes and filter screen, they will not only block the ventilation channels, but also cause the vacuum degree to drop, ultimately resulting in a significant reduction in the overall adsorption force of the suction cup and affecting the stability of the panel fixation. Utility Model Content

[0004] To address the problem of difficulty in timely cleaning of impurities accumulated inside the adsorption pores, this invention proposes a liquid crystal display panel cutting fixture to overcome the aforementioned technical problems in existing related technologies.

[0005] To solve the above-mentioned technical problems, this utility model is achieved through the following technical solution:

[0006] This utility model is a liquid crystal display panel cutting fixture, including a placement plate. The top of the placement plate is provided with a plurality of adsorption holes. The bottom of the placement plate is provided with a flow guiding component corresponding to the plurality of adsorption holes. One end of the flow guiding component is provided with an extraction component. One end of the extraction component is provided with a collection component. Both the flow guiding component and the extraction component are provided with sealing components. The top of the placement plate is provided with a positioning component.

[0007] The extraction component is used to extract the gas inside the flow guiding component so that the adsorption hole can adsorb the liquid crystal display screen. The two sets of sealing components are used to alternately open and close the flow guiding component and the extraction component so that when the extraction component is transporting gas, the debris inside the extraction component falls directly into the inside of the collection component under the blowing of the airflow.

[0008] Furthermore, the flow guiding assembly includes a flow guiding tube, with multiple flow guiding tubes provided at the bottom of the placement plate. Several branch tubes are fixedly connected to the top of the flow guiding tubes, and the top ends of the branch tubes are fixedly connected to the placement plate. Each branch tube corresponds to an adsorption hole.

[0009] Furthermore, the extraction assembly includes an L-shaped extraction tube, which is fixedly connected to one side of the guide tube. One end of the L-shaped extraction tube is fixedly connected to a diversion box, and one side of the diversion box is fixedly connected to a connecting pipe. A filter screen is fixedly connected inside the L-shaped extraction tube.

[0010] Furthermore, the collection component includes a collection frame, which is fixedly connected to the other end of the L-shaped extraction tube. A collection box is movably connected inside the collection frame, and a handle is fixedly connected to one side of the collection box.

[0011] Furthermore, the sealing assembly includes a first rotating shaft and a second rotating shaft. The first rotating shaft passes through all the guide tubes, and the second rotating shaft passes through all the L-shaped extraction tubes. A first sealing disc is rotatably connected inside each of the guide tubes, and a number of the first sealing discs are fixedly connected to the first rotating shaft. A second sealing disc is rotatably connected inside each of the L-shaped extraction tubes, and a number of the second sealing discs are fixedly connected to the second rotating shaft.

[0012] Furthermore, a storage box is fixedly installed on the top of the collection frame, and one end of the first rotating shaft and the second rotating shaft both pass through the storage box. The storage box contains two meshing gears, which are fixedly connected to the first rotating shaft and the second rotating shaft, respectively. A motor is fixedly installed on the outside of the storage box, and the output end of the motor is fixedly connected to the second rotating shaft.

[0013] Furthermore, the positioning component includes a support leg, which is fixedly connected to the bottom of the placement plate. A longitudinal adjusting screw is rotatably connected to the inner side of the support leg. A longitudinal positioning frame is threadedly connected to the outer surface of the longitudinal adjusting screw. A transverse adjusting screw is rotatably connected to the top of the longitudinal positioning frame. A transverse positioning block is threadedly connected to the outer surface of the transverse adjusting screw. A control panel is fixedly connected to one end of both the longitudinal and transverse adjusting screws.

[0014] This utility model has the following beneficial effects:

[0015] 1. This utility model allows the flow guiding component to be closed by rotating two sets of sealing components, while simultaneously opening the connection between the extraction component and the collection component. At this time, the extraction component begins to deliver gas, and the gas flowing inside blows away the accumulated debris, causing the debris to fall directly into the collection component. The above structural design only requires rotating two sets of sealing components, and then the airflow delivered by the extraction component allows the collection component to automatically complete the debris collection. Since the entire cleaning process is convenient to operate, this operation can be performed every time the display screen is clamped, thereby effectively avoiding the problem of decreased adsorption force of the device due to debris accumulation.

[0016] 2. This utility model drives a second rotating shaft to rotate via a motor. The rotating second rotating shaft drives a first rotating shaft to rotate via two meshing gears. At this time, the two rotating shafts can drive the corresponding sealing discs to rotate, thereby realizing the alternating opening and closing of the guide tube and the L-shaped extraction tube. The above configuration allows the motor to be driven directly when switching between the adsorption and cleaning working states of the device, without complicated operation steps, which significantly improves the ease of use of the equipment.

[0017] Of course, any product implementing this utility model does not necessarily need to achieve all of the advantages described above at the same time. Attached Figure Description

[0027] The technical solutions of the utility model embodiments will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the utility model, and not all embodiments. Based on the embodiments of the utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the utility model.

[0028] In the description of this utility model, it should be understood that the terms "opening", "upper", "lower", "top", "middle", "inner", etc., which indicate orientation or positional relationship, are only for the convenience of describing the utility model and simplifying the description, and do not indicate or imply that the components or elements referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on the utility model.

[0029] Please see Figures 1-6 As shown, this utility model is a liquid crystal display panel cutting fixture, including a placement plate 1. The top of the placement plate 1 is provided with a plurality of adsorption holes 2. The bottom of the placement plate 1 is provided with a flow guiding component 3 corresponding to the plurality of adsorption holes 2. One end of the flow guiding component 3 is provided with an extraction component 4. One end of the extraction component 4 is provided with a collection component 5. Both the flow guiding component 3 and the extraction component 4 are provided with a sealing component 6. The top of the placement plate 1 is provided with a positioning component 7.

[0030] The extraction component 4 is used to extract the gas inside the flow guiding component 3 so that the adsorption hole 2 can adsorb the liquid crystal display screen. The two sets of sealing components 6 are used to alternately open and close the flow guiding component 3 and the extraction component 4 so that when the extraction component 4 is transporting gas, the debris inside the extraction component 4 falls directly into the collection component 5 under the blowing of the airflow.

[0031] The extraction component 4 extracts the gas inside the flow guiding component 3, thereby creating a negative pressure inside the flow guiding component 3. At this time, the several adsorption holes 2 connected to the flow guiding component 3 generate adsorption force and adsorb the display screen placed on the placement plate 1. After the display screen is cut, the two sets of sealing components 6 are rotated, thereby closing the flow guiding component 3 and opening the connection end of the extraction component 4. At this time, the extraction component 4 transports airflow, and the debris inside the connection end of the extraction component 4 can fall directly into the collection component 5 under the blowing of the airflow.

[0032] By rotating the two sets of sealing components 6, the flow guiding component 3 can be closed, while the connection between the extraction component 4 and the collection component 5 is opened. At this time, the extraction component 4 begins to deliver gas. When the gas flows inside, it blows away the accumulated debris, causing the debris to fall directly into the collection component 5. The above structural design only requires rotating the two sets of sealing components 6, and then the airflow delivered by the extraction component 4 can make the collection component 5 automatically complete the debris collection. Since the entire cleaning process is convenient to operate, this operation can be performed every time the display screen is clamped, thereby effectively avoiding the problem of the device's adsorption force decreasing due to debris accumulation.

[0033] In one embodiment, the flow guiding component 3 includes a flow guiding pipe 301. Multiple flow guiding pipes 301 are provided at the bottom of the placement plate 1. Several branch pipes 302 are fixedly connected to the top of the flow guiding pipe 301. The top ends of the branch pipes 302 are fixedly connected to the placement plate 1. The several branch pipes 302 correspond one-to-one with the adsorption holes 2.

[0034] The extraction component 4 extracts the airflow inside the guide tube 301, creating a negative pressure inside the guide tube 301. At this time, the adsorption hole 2 connected to the branch tube 302 generates adsorption force under the action of negative pressure, thereby fixing the display screen. Since both the guide tube 301 and the branch tube 302 are exposed, the operator can easily check the condition inside the guide tube 301 when the adsorption force of the device is insufficient.

[0035] In one embodiment, the extraction component 4 includes an L-shaped extraction tube 401, which is fixedly connected to one side of the guide tube 301. One end of the L-shaped extraction tube 401 is fixedly connected to a diversion box 402, and one side of the diversion box 402 is fixedly connected to a connecting tube 403. A filter screen 404 is fixedly connected inside the L-shaped extraction tube 401.

[0036] The connecting pipe 403 is connected to the vacuum pump. When adsorbing the display screen, the vacuum pump draws air from the inside of the distribution box 402 through the connecting pipe 403, creating a negative pressure inside the distribution box 402. This causes the distribution box 402 to draw air from the inside of the guide pipe 301 through the L-shaped extraction pipe 401, creating a negative pressure inside the guide pipe 301. The debris generated during the cutting of the display screen is adsorbed by the negative pressure of the guide pipe 301 and falls into the inside of the guide pipe 301 through the adsorption hole 2 and the branch pipe 302. Under the guidance of the guide pipe 301, it falls directly into the inside of the L-shaped extraction pipe 401. Since a filter screen 404 is provided at one end of the L-shaped extraction pipe 401, the debris will accumulate inside the L-shaped extraction pipe 401.

[0037] In one embodiment, the collection component 5 includes a collection frame 501, which is fixedly connected to the other end of the L-shaped extraction tube 401. A collection box 502 is movably connected inside the collection frame 501, and a handle 503 is fixedly connected to one side of the collection box 502.

[0038] When extracting debris accumulated inside the L-shaped extraction tube 401, the two sets of sealing components 6 are driven, thereby closing several guide tubes 301 and opening the other end of the L-shaped extraction tube 401. Then, the vacuum pump transports airflow into the L-shaped extraction tube 401 through the connecting pipe 403 and the diversion box 402. At this time, the debris inside the L-shaped extraction tube 401 is blown directly into the collection box 502 by the airflow, so that the collection box 502 can collect the debris. When cleaning the collected debris, the collection box 502 can be pulled out from the collection frame 501 through the handle 503.

[0039] In one embodiment, the sealing assembly 6 includes a first rotating shaft 601 and a second rotating shaft 602. The first rotating shaft 601 passes through all the guide tubes 301, and the second rotating shaft 602 passes through all the L-shaped extraction tubes 401. A first sealing disc 603 is rotatably connected inside each of the guide tubes 301, and a number of first sealing discs 603 are fixedly connected to the first rotating shaft 601. A second sealing disc 604 is rotatably connected inside each of the L-shaped extraction tubes 401, and a number of second sealing discs 604 are fixedly connected to the second rotating shaft 602.

[0040] By rotating the first rotating shaft 601, all the first sealing discs 603 rotate inside the corresponding guide tubes 301. By rotating the second rotating shaft 602, all the second sealing discs 604 rotate inside the L-shaped extraction tube 401. In this configuration, when the second sealing discs 604 close the bottom of the L-shaped extraction tube 401, the first sealing discs 603 are in the open state, allowing the device to adsorb the display screen. When the first sealing discs 603 seal the guide tube 301, the second sealing discs 604 are in the open state, allowing the debris accumulated inside the L-shaped extraction tube 401 to fall directly into the collection box 502. In summary, by simply rotating the two rotating shafts, the device can switch between adsorption and cleaning modes.

[0041] In one embodiment, for the collection box 501, a storage box 605 is fixedly installed on the top of the collection box 501. One end of the first rotating shaft 601 and the second rotating shaft 602 both pass through the storage box 605. The storage box 605 is provided with two meshing gears 606 inside. The two gears 606 are fixedly connected to the first rotating shaft 601 and the second rotating shaft 602 respectively. A motor 607 is fixedly installed on the outside of the storage box 605. The output end of the motor 607 is fixedly connected to the second rotating shaft 602.

[0042] By driving the second shaft 602 to rotate via the motor 607, the rotating second shaft 602 drives the first shaft 601 to rotate via two meshing gears 606. At this time, the two shafts can drive the corresponding sealing discs to rotate, thereby opening the guide tube 301 and closing the L-shaped extraction tube 401, or closing the guide tube 301 and opening the L-shaped extraction tube 401. The above settings allow the motor 607 to be driven directly when switching between the adsorption and cleaning working states of the device, making the whole operation relatively convenient.

[0043] In one embodiment, the positioning component 7 includes a support leg 701, which is fixedly connected to the bottom of the placement plate 1. A longitudinal adjusting screw 702 is rotatably connected to the inner side of the support leg 701. A longitudinal positioning frame 703 is threadedly connected to the outer surface of the longitudinal adjusting screw 702. A transverse adjusting screw 704 is rotatably connected to the top of the longitudinal positioning frame 703. A transverse positioning block 705 is threadedly connected to the outer surface of the transverse adjusting screw 704. A control disk 706 is fixedly connected to one end of both the longitudinal adjusting screw 702 and the transverse adjusting screw 704.

[0044] When cutting the display screen, the display screen is placed on the placement plate 1, with the corners of the display screen in contact with the longitudinal positioning frame 703 and the transverse positioning block 705. The longitudinal positioning frame 703 and the transverse positioning block 705 work together to position the display screen. The longitudinal adjusting screw 702 is rotated by the control disk 706 at one end, which moves the longitudinal positioning frame 703 on the placement plate 1. The transverse adjusting screw 704 is rotated by the control disk 706 at one end, which moves the transverse positioning block 705 on the longitudinal positioning frame 703. This arrangement allows the transverse positioning block 705 to move freely on the placement plate 1, enabling the device to better position display screens of different sizes.

[0045] Through the above technical solution, 1. By rotating the two sets of sealing components 6, the flow guiding component 3 can be closed, while the connection between the extraction component 4 and the collection component 5 is opened. At this time, the extraction component 4 begins to deliver gas. When the gas flows inside, it blows away the accumulated debris, causing the debris to fall directly into the collection component 5. The above structural design only requires rotating the two sets of sealing components 6, and then the airflow delivered by the extraction component 4 can make the collection component 5 automatically complete the debris collection. Since the entire cleaning process is convenient to operate, this operation can be performed every time the display screen is clamped, thereby effectively avoiding 1. This eliminates the problem of decreased adsorption force due to debris accumulation; 2. By driving the second shaft 602 to rotate through the motor 607, the rotating second shaft 602 drives the first shaft 601 to rotate through two meshing gears 606. At this time, the two shafts can drive the corresponding sealing disc to rotate, thereby realizing the alternating opening and closing of the guide tube 301 and the L-shaped extraction tube 401. The above settings allow the motor 607 to be driven directly when switching between the adsorption and cleaning working states of the device, without complicated operation steps, which significantly improves the ease of use of the equipment.
