Description

Technical Field

[0001] This invention relates to the field of cleaning technology for liquid crystal glass cutting equipment, and more specifically to a belt cleaning device for liquid crystal glass cutting equipment. Background Technology

[0002] In the production process of LCD glass substrates, the cutting equipment is one of the key pieces of equipment. It transports the glass substrate via a belt conveyor and completes the cutting operation. Glass shavings, dust, and other impurities generated during the cutting process easily adhere to the surface of the belt conveyor. If not cleaned in time, they will scratch the surface of the glass substrate during subsequent transport, causing product defects and reducing yield.

[0003] Currently, the industry mainly uses manual periodic wiping or fixed brush cleaning to clean the belts of cutting equipment. Manual wiping is inefficient, labor-intensive, and the cleaning effect is greatly affected by the operator's operation, making it difficult to ensure consistent cleaning. In the fixed brush cleaning method, the brush is always in contact with the belt, which not only causes additional wear on the belt and shortens its lifespan, but also the cleaning effect drops sharply after the brush wears down. In addition, it is impossible to flexibly control the cleaning time according to production needs, making it difficult to meet the requirements of high yield and low maintenance costs in modern LCD glass production.

[0004] Therefore, there is an urgent need for a cleaning device that can automatically and efficiently clean shaft belts while reducing belt wear and maintenance costs, in order to solve the problems existing in the prior art. Summary of the Invention

[0005] To address the shortcomings of existing technologies, this invention provides a belt cleaning device for liquid crystal glass cutting equipment, which solves the problems mentioned in the background art.

[0006] To achieve the above objectives, the present invention provides the following technical solution:

[0007] The belt cleaning device for LCD glass cutting equipment includes: a cutting platform, which has multiple sets of grooves extending along the conveying direction inside;

[0008] The conveying assembly includes multiple sets of conveyor frames extending along the conveying direction, with each set of slots containing one set of conveyor frames and a conveyor belt built into each set; a first lifting drive component is installed on top of the multiple sets of conveyor frames.

[0009] The cleaning assembly includes multiple sets of receiving boxes. Each set of conveyor belts has a set of receiving boxes at its bottom. Each set of receiving boxes contains a set of roller brushes. The roller brushes are used to clean glass impurities adhering to the outer wall of the conveyor belt from the bottom surface. The receiving boxes are used to collect impurities that have been transferred during cleaning. Multiple sets of roller brushes share a set of rotating components. Multiple sets of receiving boxes are mounted on a lifting platform. A second lifting drive component is mounted at the bottom of the lifting platform.

[0010] The material collection assembly includes a material collection trough located below the outlet of multiple sets of receiving boxes. The material collection trough is fixedly connected to a lifting platform and is used to receive impurities discharged from the multiple sets of receiving boxes. A pushing component is installed on one side of the top of the material collection trough, and a recycling turnover box is provided at the outlet end of the material collection trough. The pushing component is used to push the material collection trough into the recycling turnover box.

[0011] The sealing component is located on the outside of the pushing component. The sealing component is used to seal the outlet of each receiving box before the pushing component performs the pushing operation, so as to prevent the receiving box from discharging material to the reset side of the pushing component.

[0012] Furthermore, the first lifting drive component includes two sets of symmetrically arranged longitudinal brackets, which are respectively placed at the bottom ends of multiple sets of conveyor frames. Each set of longitudinal brackets has two sets of first drive rods installed at its bottom. The three sets of conveyor frames share a set of drive shafts, one end of which is connected to a first motor.

[0013] Furthermore, the bottom surface of the receiving box is inclined, the top of the receiving box has a feeding port, and the side of the receiving box has a discharging port.

[0014] Furthermore, the rotating component includes a transmission rod that rotates through each set of receiving boxes and is fixedly connected to the roller brush. One end of the transmission rod is connected to a second motor.

[0015] Furthermore, the pushing component includes a screw guide rail, which is placed parallel to the top outer side of the collecting trough. A sliding plate is slidably installed inside the screw guide rail, and a pushing plate is provided at the bottom end of the sliding plate. The pushing plate is embedded in the collecting trough, and the side cross-section of the collecting trough is U-shaped.

[0016] Furthermore, the material collection trough is fixedly connected to the lifting platform via the second positioning frame, and the screw guide rail is fixedly connected to the material collection trough via the first positioning frame.

[0017] Furthermore, the enclosure component includes a hanging plate, the bottom surface of which is provided with multiple sets of sealing plates. Each set of sealing plates corresponds to vertically sliding and sealing the discharge port of a set of receiving boxes. The hanging plate is located above the material collection trough. Multiple sets of top plates are provided on the outer side of the hanging plate. Each set of top plates has a set of second drive rods on the bottom surface of its outer end. The second drive rods are fixedly connected to the material collection trough through a third positioning frame. The second drive rods are located on the outer side of the screw guide rail.

[0018] Furthermore, the second lifting drive component includes a scissor lift frame, with a lifting platform connected to the top of the scissor lift frame and a support plate connected to the bottom of the scissor lift frame.

[0019] Furthermore, the surface of the tray is provided with a frame, into which the recycling bin is inserted.

[0020] This invention provides a belt cleaning device for liquid crystal glass cutting equipment. Compared with the prior art, it has the following advantages:

[0021] When the belt needs cleaning, the bristles of the roller brush contact the belt surface, and the rotating roller brush sweeps away glass shards, dust, and other impurities from the belt surface. The impurities are carried away by the bristles, achieving a cleaning effect. During non-cleaning periods, the roller brush descends, always remaining separated from the belt, avoiding long-term contact wear between the belt and the roller brush, and effectively extending the service life of both the belt and the roller brush.

[0022] The collection trough centrally receives impurities discharged from multiple sets of receiving boxes. With the help of the screw-driven pushing component, the accumulated impurities can be pushed to the recycling turnover box. There is no need to clean the receiving boxes one by one, making maintenance convenient and efficient. The U-shaped trough pushes the impurities thoroughly without leaving any residue, resulting in high efficiency in impurity recycling and processing. The plug-in recycling turnover box is easy to pick up and put in, facilitating the centralized transfer and processing of impurities.

[0023] Before the material is pushed and cleaned, the sealing component can simultaneously block the discharge ports of all receiving boxes, preventing continuous material from accumulating on the reset side of the pusher plate during the cleaning process, ensuring thorough cleaning without residue, and effectively reducing dead corners of material accumulation in the tank.

[0042] To address the technical problems in the background section, the following belt cleaning device for liquid crystal glass cutting equipment is provided:

[0043] Combination Figures 1-9 As shown, the present invention discloses a belt cleaning device for a liquid crystal glass cutting equipment. This device employs a lifting conveyor switching mechanism, a bottom roller brush 450° reverse cleaning system, inclined material collection and centralized pushing, and pre-discharge sealing to prevent residue. It enables online, non-stop cleaning, thorough impurity collection, and convenient cleaning. The overall structure includes a cutting platform 100, a conveying assembly 200, a cleaning assembly 400, a material collection assembly 500, and a sealing assembly 600, with the specific structural layout as follows:

[0044] The cutting platform 100 is the bearing reference base for glass cutting. It has multiple sets of notches extending along the conveying direction to accommodate the conveying assembly 200 and provide lifting and clearance space. The top surface of the platform is a flat cutting surface to ensure the flatness accuracy of the glass substrate cutting.

[0045] The conveying assembly 200 includes multiple sets of conveying frames 230 extending along the conveying direction. Each set of slots is equipped with a set of conveying frames 230, and the conveying frames 230 have a built-in conveying belt 231. The multiple sets of conveying frames 230 are equipped with a first lifting drive component, which can drive the conveying frames 230 to lift as a whole, so as to realize the switching between the conveying station and the cutting station.

[0046] The first lifting drive component includes two sets of symmetrically arranged longitudinal brackets 220, which are respectively placed at the bottom ends of multiple sets of conveyor frames 230. Each set of longitudinal brackets 220 has two sets of first drive rods 210 installed at the bottom. The three sets of conveyor frames 230 share a set of drive shafts 240, one end of which is connected to a first motor 241 to realize the synchronous operation of multiple sets of conveyor belts 231.

[0047] The cleaning component 400 includes multiple sets of receiving boxes 440. Each set of receiving boxes 440 is located at the bottom of each conveyor belt 231. Each set of receiving boxes 440 contains a set of roller brushes 450, which clean glass impurities adhering to the outer wall of the conveyor belt 231 from the bottom surface. The receiving boxes 440 also collect impurities dislodged by the cleaning brushes. Multiple sets of roller brushes 450 share a single rotating component for synchronized cleaning. All sets of receiving boxes 440 are mounted on a lifting platform 420. A second lifting drive component is installed at the bottom of the lifting platform 420, which can drive the entire cleaning component 400 to rise and fall, adjusting the contact pressure between the roller brushes 450 and the belt. The roller brushes 450 are L2520×Φ120 type nylon roller brushes, with a length matching the width of the belt of the cutting equipment, ensuring complete coverage of the belt surface.

[0048] The bottom surface of the receiving box 440 is inclined, the top of the receiving box 440 has a feed port, and the side of the receiving box 440 has a discharge port, which facilitates the automatic discharge of impurities along the inclined surface. The rotating component includes a transmission rod 460, which rotates through each set of receiving boxes 440 and is fixedly connected to the roller brush 450. One end of the transmission rod 460 is connected to the second motor 430.

A pushing component is installed on one side of the top of the material collection trough 520, and a recycling turnover box 530 is provided at the outlet end of the material collection trough 520. The pushing component is used to push the impurities in the material collection trough 520 to the recycling turnover box 530.

[0051] The feeding component includes a screw guide rail 510, which is positioned parallel to the top outer side of the collecting trough 520. A sliding plate is slidably installed inside the screw guide rail 510, and a feeding plate 511 is provided at the bottom end of the sliding plate. The feeding plate 511 is embedded in the collecting trough 520, and the side cross-section of the collecting trough 520 is U-shaped. The collecting trough 520 is fixedly connected to the lifting platform 420 through a second positioning frame 521, and the screw guide rail 510 is fixedly connected to the collecting trough 520 through a first positioning frame 512.

[0052] The surface of the pallet 300 is provided with a frame 310, and the recycling turnover box 530 is inserted into the frame 310. It is convenient to insert and remove, and facilitates centralized transfer and processing of impurities.

[0053] The sealing component 600 is located on the outside of the pushing component and is used to seal the outlet of each receiving box 440 before the pushing component performs the pushing operation, so as to prevent the receiving box 440 from continuously discharging material to the reset side of the pushing component and ensure that the pushing and cleaning is thorough and without residue.

[0054] The enclosure component 600 includes a hanging plate 640, the bottom surface of which is provided with multiple sets of sealing plates 650, each set of sealing plates 650 corresponding to vertically sliding and sealing the discharge port of a set of receiving boxes 440; the hanging plate 640 is located above the collecting trough 520, and the outer side of the hanging plate 640 is provided with multiple sets of top plates 630, the bottom surface of the outer end of each set of top plates 630 is provided with a set of second drive rods 620, the second drive rods 620 are fixedly connected to the collecting trough 520 through a third positioning frame 610, and the second drive rods 620 are located outside the screw guide rail 510.

[0055] Working principle and usage process of this invention:

[0056] S1. Switching between conveyor and cutting stations:

[0057] When the glass substrate to be cut is input, the first drive rod 210 drives the longitudinal support 220 to lift up, which drives multiple sets of conveyor frames 230 to rise synchronously, so that the top surface of the conveyor belt 231 is flush with the input mechanism; the glass substrate is transferred to the conveyor belt 231, and the first motor 241 drives each conveyor belt 231 to run synchronously through the drive shaft 240 to complete the feeding and conveying.

[0058] After the material is received, the first drive rod 210 drives the longitudinal support 220 to descend, the conveyor 230 falls back into the notch, and the glass substrate falls smoothly onto the cutting platform 100; the cutting mechanism moves horizontally and vertically at the top of the cutting platform 100 to complete the cutting operation of the glass substrate; after the cutting is completed, the conveyor 230 rises again, and the conveyor belt 231 runs to output the cut glass substrate.

[0059] S2. Online belt cleaning:

[0060] The scissor lift 410 drives the lifting platform 420 to lift, so that the top surface of each set of roller brushes 450 contacts the bottom surface of the conveyor belt 231; the second motor 430 drives each roller brush 450 to rotate synchronously through the transmission rod 460, and the conveyor belt 231 rotates synchronously and in the opposite direction to the rotation of the roller brushes 450. The roller brushes 450 brush away glass fragments and fine powder impurities attached to the surface of the conveyor belt 231 in the opposite direction, so as to avoid residual impurities scratching the subsequent glass substrate.

[0061] The glass impurities removed by the cleaning brush fall into the receiving box 440 below, and are automatically discharged from the discharge port into the collection trough 520 along the inclined bottom surface of the receiving box 440, thus completing the centralized collection of impurities.

[0062] S3. Sealing before discharge:

[0063] After the impurities have been collected for a period of time, the collection trough 520 needs to be cleaned. Before cleaning, the discharge ports of each receiving box 440 should be closed to prevent continuous material from falling during the cleaning process and to avoid glass impurities from being discharged to the rear reset side of the push plate 511.

[0064] The second drive rod 620 drives the top plate 630 to descend, which in turn drives the hanging plate 640 to descend as a whole. Each set of sealing plates 650 descends simultaneously, correspondingly sealing the discharge port of each receiving box 440 and blocking the material drop path.

[0065] S4. Centralized material pushing and recycling:

[0066] After sealing is completed, the screw guide rail 510 drives the sliding plate to move the pusher plate 511 forward along the collection trough 520. The pusher plate 511 pushes out the glass impurities accumulated in the collection trough 520 and sends them into the recycling transfer box 530 at the end. After cleaning, the pusher plate 511 resets, the second drive rod 620 drives the lifting plate 640 to rise, and the sealing plate 650 disengages from the discharge port, restoring the impurity collection state. The operator can then remove the recycling transfer box 530 from the insertion frame 310 and transfer the glass impurities to the unified processing area.
