Description

Technical Field

[0001] This invention relates to the field of liquid crystal glass substrate technology, and more specifically to a dust removal device for cutting liquid crystal glass substrates. Background Technology

[0002] With the continuous development of electronic technology, TFT-LCD (Liquid Crystal Display) is widely used in various electronic products. The liquid crystal substrate is an important component of the display. In the production process of liquid crystal substrate, the precision cutting process mainly involves cutting the edges of the substrate. However, a large amount of dust is generated during the cutting process. This dust may not only affect product quality, but also harm the health of operators and the production environment. Cleaning equipment is needed.

[0003] The dust removal device is mainly used in the Bar suction structure of the cutting machine breaking equipment. During cutting, the dust-laden air can be sucked into the equipment through the pipeline system to complete the cleaning. The Bar suction structure is an effective dust removal device on the cutting machine breaking equipment. Through reasonable design and layout, it can significantly reduce the dust generated during the cutting process, improve the cleanliness of the production environment, and protect the health of operators and the normal operation of the equipment.

[0004] As can be seen from the above, during the LCD substrate production process, the equipment generates a lot of cutting dust. Although this dust is filtered through the internal filtration structure of the device, prolonged operation can cause blockage of the filtration structure, requiring frequent cleaning by personnel. Otherwise, the operation of the device will be affected.

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

[0019] The dust removal components and dust collection bin are quickly linked by the drive components. After dust collection is completed, the device can be separated, causing the device to leave the working state, releasing the docking and positioning of the dust collection bin, and pushing the dust collection bin outward. This allows personnel to quickly handle the impurities in the dust collection bin and avoid structural interference.

[0020] The backflush air guide component not only assists the vacuum cleaner in sucking up impurities and ensuring the suction power of the device, but also allows switching of operating modes. When not vacuuming, it performs backflush operation by using air collection and pressurization to backflush the filter structure in the dust removal component, thereby blowing away the dust attached to the filter structure and realizing the self-cleaning operation of the device.

[0031] 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.

[0032] Example 1

[0033] To address the technical problems in the background art, the following dust removal device for cutting liquid crystal glass substrates is provided:

[0034] Combination Figures 1-8As shown, the present invention provides a dust removal device for cutting liquid crystal glass substrates, including a base 1 and a dust removal component 7. An air guide box 3 is fixedly installed on the top of the base 1, and an air storage chamber 31 and an installation chamber 32 are respectively provided inside the air guide box 3. A backflow air guide component 2 is assembled between the air storage chamber 31 and the installation chamber 32. A drive component 8 is assembled on the base 1 on one side of the air guide box 3. The drive component 8 is provided with a lifting end and a sliding end. The dust removal component 7 is installed on the lifting end, and a dust collection bin 5 is loaded on the sliding end. The dust removal component 7 and the dust collection bin 5 are connected to each other. A dust scraper component 9 is fixedly installed in the lower part of the dust removal component 7. A vacuum cleaner 4 is installed on the front of the dust removal component 7. A vacuum cleaner component 6 is installed on the input end of the vacuum cleaner 4.

[0035] During this process, the dust collection component 6 is assembled with the working part of the breaking device. When the breaking device is operating, it works in conjunction with the vacuum cleaner 4. This allows the dust and impurities generated by the equipment to be collected by the dust collection component 6. Through the cooperation of the dust removal component 7 and the dust scraping component 9, the air velocity at the bottom of the dust collector is reduced as much as possible. Coarse dust falls directly into the dust collection box, while fine dust rises with the airflow and settles on the outer surface of the filter with surface filtration function. In this way, the dust is directly separated onto the surface without penetrating into the filter material, making the filter in the dust removal component 7 easy to clean. The drive component 8 then controls the dust removal component 7 and... The dust collection bin 5 is linked quickly. After dust collection is completed, the device can be separated, causing the device to leave the working state, releasing the docking and positioning of the dust collection bin 5, and pushing the dust collection bin 5 outward. This allows personnel to quickly handle the impurities in the dust collection bin 5 and avoid structural interference. The backflushing air guide component 2 not only assists the vacuum cleaner 4 in sucking up impurities and ensures the suction power of the device, but also switches the working state. When not vacuuming, it performs backflushing operation, using the air collection and pressurization method to backflush the filter structure in the dust removal component 7, blowing away the dust attached to the filter structure and realizing the self-cleaning operation of the device.

[0036] The backflushing air guide assembly 2 includes an installation cavity 21, an exhaust fan 22, an air guide pipe 27, and an air injection pipe 28. An air guide pipe 27 is installed between the air storage chamber 31 and the installation chamber 32. The bottom end of the air guide pipe 27 is connected to the installation cavity 21, and the exhaust fan 22 is installed inside the installation cavity 21. The top of the installation cavity 21 is connected to the air injection pipe 28 extending into the air storage chamber 31. The dust removal assembly 7 includes a dust collection box 71, a backflushing component 72, a filter component 73, and a conical hopper 74. The dust collection box 71 is fixedly installed on the lifting end of the drive assembly 8. A conical bucket 74 is fixedly installed at the bottom of the base 1. A back-blowing component 72 is installed inside the dust collection box 71. A filter component 73 is fixedly installed inside the dust collection box 71 below the back-blowing component 72. The drive assembly 8 includes a lifting component 81, a sliding component 82, and a drive component 83. A lifting component 81 is fixedly installed on one side of the top of the base 1. A sliding component 82 is slidably installed on the base 1 on one side of the lifting component 81. The dust collection bucket 5 is placed on the sliding component 82. The lifting component 81 and the sliding component 82 are connected by a joint transmission through the drive component 83.

[0037] During this process, dust enters the dust collection box 71. Coarse dust falls directly into the dust collection bin 5, while fine dust rises with the airflow and settles on the outer surface of the filter element 73, which has surface filtration function. In this way, the dust is directly separated onto the surface, and air is then expelled through and enters the air duct 27. With the cooperation of the mounting cavity 21 and the exhaust fan 22, the air is quickly discharged. After dust removal is completed, the air duct 27 is closed, and then the exhaust fan 22 is started to blow air in reverse, guiding the gas into the air storage chamber 31. During this process, the pressure gauge on the top of the air duct box 3 can be used to check the pressure. The process is displayed, and then the back-blowing component 72 is lowered, causing it to extend into the filter component 73 and blow air, causing the back-blowing component 72 to blow air back onto the filter component 73, causing the dust on the filter component 73 to fall off. This process is repeated several times to complete the cleaning. After completion, the drive component 83 can be activated, which simultaneously drives the lifting component 81 and the sliding component 82. At that time, the lifting component 81 drives the dust collection box 71 to rise, and the sliding component 82 drives the dust collection bin 5 to push outward, allowing personnel to clean the impurities in the dust collection bin 5.

[0038] Example 2

[0039] like Figure 1 and Figure 8 As shown, based on the above embodiments, this embodiment further provides the following:

[0040] In this embodiment, the backflow air guiding assembly 2 further includes an electronically controlled valve 23, an exhaust pipe 24, a pipe silencer 25, an air inlet pipe 26, a one-way air inlet valve 29, and a first flexible hose 210. The air inlet pipe 26 is fixedly installed on the air guiding pipe 27, and the air inlet pipe 26 is located above the mounting cavity 21. The exhaust pipe 24 is connected to the bottom of the mounting cavity 21. The electronically controlled valve 23 is fixedly installed on the exhaust pipe 24, the air inlet pipe 26, and the air guiding pipe 27. The pipe silencer 25 is connected to the air outlet of the exhaust pipe 24 and the air inlet pipe 26. The one-way air inlet valve 29 is fixedly installed on the air injection pipe 28. The first flexible hose 210 is connected to the top of the air guiding pipe 27. The air guiding pipe 27 is connected to the dust collection box 71 through the first flexible hose 210.

[0041] After the dust process is completed, the air duct 27 can be closed by the electric control valve 23. At the same time, the electric control valve 23 closes the exhaust pipe 24 and opens the air intake pipe 26. Then the exhaust fan 22 is started again, and the outside air enters through the air intake pipe 26 and is injected into the air storage chamber 31 through the air injection pipe 28 until a pressurization effect is produced. Then the device performs backflushing operation.

[0042] During this period, when the lifting component 81 drives the dust collection box 71 to rise, the first hose 210 extends in coordination.

[0043] During this period, when the exhaust pipe 24 and the intake pipe 26 are exhausting or intakeing air, they can be combined with the pipe muffler 25 to effectively reduce the generation of wind noise.

[0044] In this embodiment, the vacuuming assembly 6 includes an air guide tube 61, an air inlet 62, a suction chamber 63, a rubber scraper 64, a suction cup 65, and a second hose 66. The input end of the vacuum cleaner 4 is connected to the second hose 66. The vacuum cleaner 4 is connected to the air guide tube 61 through the second hose 66. The air guide tube 61 is connected to the suction chamber 63 through four sets of air inlets 62. The top of the suction chamber 63 is evenly distributed with connected suction cups 65. The edge of the suction chamber 63 is fixedly installed with a rubber scraper 64.

[0045] During operation, the suction chamber 63 is installed on the working part of the breaking device. The vacuum cleaner 4 is started first, and the vacuum cleaner 4 applies negative pressure to the second hose 66. At that time, the dust generated by the breaking device will be sucked up by the cooperation between the suction cup 65 and the rubber scraper 64, causing the dust to enter the suction chamber 63 and then into the second hose 66 to complete the conveying.

[0046] In this embodiment, the back-blowing component 72 includes an annular cavity 721, an electric telescopic frame 722, a third hose 723, an air blowing pipe 724, air blowing holes 725, and a connector 726. The top of the dust collector 71 is fixedly installed with the connector 726. The top of the connector 726 is connected to the third hose 723, which communicates with the air storage chamber 31. An air valve is installed on the third hose 723. The top of the dust collector 71 is fixedly installed with the electric telescopic frame 722. The output end of the electric telescopic frame 722 is connected to the annular cavity 721. The top of the annular cavity 721 is connected to the connector 726 through a fourth hose 727. The bottom of the annular cavity 721 is evenly distributed with communicating air blowing pipes 724, and air blowing holes 725 are evenly distributed on the air blowing pipes 724.

[0047] During this process, when the device enters the backflushing state, the electric telescopic frame 722 needs to be activated. The electric telescopic frame 722 drives the annular cavity 721 to descend, causing the air blowing pipe 724 at the bottom of the annular cavity 721 to extend into the filter component 73. When the high-pressure gas in the air storage chamber 31 enters the annular cavity 721, it will enter the air blowing pipe 724 through the annular cavity 721. Then, it blows air onto the filter component 73 through the air blowing hole 725 on the air blowing pipe 724, causing the dust attached to the filter component 73 to fall off, thus achieving the cleaning treatment of the filter component 73.

[0048] In this embodiment, the filter component 73 includes a mounting frame 731 and textile filter bags 732. The mounting frame 731 is fixedly installed inside the dust collection box 71. A plurality of textile filter bags 732 are connected and installed on the mounting frame 731, and the textile filter bags 732 are arranged in a ring array. The textile filter bags 732 correspond to the air blowing pipe 724.

[0049] Based on the above, since the textile filter bag 732 and the air blowing pipe 724 correspond to each other, when the device enters the backflushing state, the electric telescopic frame 722 needs to be activated. The electric telescopic frame 722 drives the annular cavity 721 to descend, causing the air blowing pipe 724 at the bottom of the annular cavity 721 to extend into the textile filter bag 732. Air is blown onto the textile filter bag 732 through the air blowing holes 725 on the air blowing pipe 724. In this way, the dust adhering to the outer surface of the textile filter bag 732 will fall off under the blowing, thus completing the cleaning of the textile filter bag 732 and enabling the textile filter bag 732 to continue subsequent filtration operations.

[0050] Example 3

[0051] like Figures 1-8 As shown, based on the above embodiments, this embodiment further provides the following:

[0052] In this embodiment, the lifting component 81 includes a column 811, a threaded rod 812, a guide block 813, a mounting port 814, and a mounting shell 815. The mounting shell 815 is fixedly installed on the top of the base 1, and the column 811 is fixedly installed on the top of the mounting shell 815. The mounting port 814 is provided on one side of the column 811. The threaded rod 812 extending into the mounting shell 815 is installed in the mounting port 814. The guide block 813 is fitted on the threaded rod 812, and the guide block 813 is installed and connected to the dust collection box 71.

[0053] Once the dust removal process is complete, the drive unit 83 can be activated. Under the transmission of the drive unit 83, the threaded rod 812 is rotated. The rotation of the threaded rod 812 generates a force with the guide block 813. Since the guide block 813 is limited by its internal mounting port 814, the guide block 813 and the threaded rod 812 move up and down under the threaded force. In this way, the guide block 813 can drive the dust collection box 71 to move up and down synchronously. After rising, the dust collection box 71 can separate from the dust collection box 5 at the bottom, causing the dust collection box 5 to enter the processing state.

[0054] In this embodiment, the sliding component 82 includes a carrier plate 821, a slide rail 822, and a connecting strip 823. The slide rail 822 is fixedly installed on the top of the base 1, and the carrier plate 821 is slidably installed on the base 1 via the slide rail 822. A placement groove is provided on the top of the carrier plate 821, and the dust collection bin 5 is placed in the placement groove. The connecting strip 823 is fixedly installed on the side of the carrier plate 821, and the carrier plate 821 is connected to the driving component 83 via the connecting strip 823.

[0055] By combining the above, once the dust removal is complete, the device can start the drive component 83. Under the transmission of the drive component 83, the connecting bar 823 is moved, and the connecting bar 823 will simultaneously move the carrier plate 821, causing the carrier plate 821 to slide smoothly on the base 1 using the bottom slide rail 822. After rising, the dust removal box 71 can be separated from the bottom dust collection box 5, and at the same time, the dust collection box 5 will also be pushed outward by the force.

[0056] In this embodiment, the driving component 83 includes a first motor 831, a ring gear 832, a rack 833, a bevel gear 834, and a rotating shaft 835. The rotating shaft 835 is installed inside the mounting housing 815. The ring gear 832 and the bevel gear 834 are fixedly installed on the rotating shaft 835. The first motor 831 is fixedly installed on the outside of the mounting housing 815, and the output end of the first motor 831 is connected to the rotating shaft 835. The rotating shaft 835 is connected to the threaded rod 812 through the bevel gear 834. The end of the connecting bar 823 is fixedly installed with the rack 833, and the rack 833 meshes with the ring gear 832 for transmission. The inner side of the mounting housing 815 is provided with a guide port that mates with the connecting bar 823.

[0057] Based on the above, once the dust removal process is complete, the first motor 831 can be started. The first motor 831 drives the rotating shaft 835 to rotate, at which point the rotation of the rotating shaft 835 can enter two states:

[0058] State 1: The rotating shaft 835 drives the threaded rod 812 through the bevel gear 834, causing the threaded rod 812 to drive the guide block 813 to move up and down;

[0059] State 2: The rotating shaft 835 drives the rack 833 through the ring gear 832, causing the rack 833 to move back and forth under the drive. In this way, the rack 833 can drive the carrier plate 821 to move back and forth through the connecting bar 823.

[0060] In this embodiment, the dust scraping assembly 9 includes a second motor 91, a scraper 92, a connecting rod 93, a dust scraping strip 94, and a motor frame 95. The motor frame 95 is fixedly installed inside the conical bucket 74, and the second motor 91 is fixedly installed in the conical bucket 74 through the motor frame 95. The output end of the second motor 91 is connected to the connecting rod 93, and the end of the connecting rod 93 is fixedly installed with the scraper 92. The dust scraping strip 94 is embedded inside the scraper 92 and contacts the inner wall of the dust collection box 71.

[0061] Once the dust removal process is complete, the second motor 91 can be started. The second motor 91 drives the connecting rod 93 to rotate, causing the scraper 92 on the connecting rod 93 to rotate synchronously. The scraper 92 will use its own scraping strips 94 to scrape the dust from the inner wall of the dust removal box 71, thus completing the cleaning operation of the inner wall of the dust removal box 71.
