Abstract
Description
Technical Field
[0001] This invention belongs to the field of conveying technology, specifically relating to conveying equipment and methods for packaging fragile thin plates, and more particularly to conveying equipment and methods for packaging glass substrates. Background Technology
[0002] Glass substrates are thin sheets of glass with extremely flat surfaces and are one of the key basic materials in the flat panel display industry. In the packaging process, glass substrates need to be horizontally transported by conveyor belt to a flipping device to complete a 180° flip for double-sided processing.
[0003] In related technologies, existing flipping devices typically insert a glass substrate into the positioning groove of the flipping device, and the flipping device rotates to flip the glass substrate.
[0004] However, when the glass substrate is inserted into the positioning groove, if the groove opening width is slightly larger than (≤1.1 times the glass substrate thickness) than the substrate thickness, friction scratches will occur on the glass substrate during insertion. Conversely, if the positioning groove opening width is too large (not less than 1.5 times the glass substrate thickness), displacement during flipping will increase the breakage rate. Furthermore, the glass substrate easily attracts environmental dust during transport, requiring simultaneous cleaning during flipping.
[0005] Therefore, ensuring the stability of the glass substrate flipping process and the efficient removal of surface impurities are technical problems that urgently need to be solved in this field.
[0006] It should be noted that the information disclosed in this background section is only for understanding the background technology of this application concept, and therefore, the above description is not considered to constitute information related to the technology. Summary of the Invention
[0007] This disclosure provides at least one conveying device and conveying method for glass substrate packaging.
[0008] In a first aspect, embodiments of this disclosure provide a conveying device for glass substrate packaging, comprising: conveyor; A flipping device is rotatably disposed in the middle of a conveyor belt; the flipping device includes: a conveyor belt extending horizontally and driving the glass substrate to move; The flipping assembly includes two oppositely arranged positioning plates and a positioning groove formed between them; A buffer is fixed to the bottom wall of the positioning groove. The buffer is a flexible part and its cross-section includes at least one recess with an opening facing the glass substrate. Cleaning strips are installed on the side wall of the positioning plate; The conveyor belt drives the glass substrate to be horizontally inserted into the positioning groove and squeezes the buffer to deform, so that one end of the glass substrate is located at the center line of the positioning groove. The flipping assembly drives the glass substrate to rotate 180° and then continues to rotate. The cleaning strip comes into contact with the surface of the glass substrate to clean impurities, and the conveyor belt drives the glass substrate to leave the positioning groove.
[0009] In one alternative embodiment, the recess of the buffer is V-shaped or U-shaped and the opening faces the glass substrate; The cleaning strip is made of silicone, and the pressure between its contact surface with the glass substrate is ≤0.05N / mm². The drive roller axis of the flipping assembly is located above the conveyor belt, and when the glass substrate comes into contact with the buffer, the positioning plate forms an inclination angle of 1°-5° with the horizontal plane.
[0010] In one optional embodiment, the positioning groove is evenly distributed with a plurality of nozzles along its length, the nozzles being disposed on both sides of the buffer and connected to a compressed air pump. When the sidewall of the glass substrate is attached to a positioning plate, the nozzle near the sidewall of the other positioning plate blows air outward to remove static electricity from the outer wall of the glass substrate.
[0011] In one optional embodiment, the opening width of the positioning groove is not less than 1.5 times the thickness of the glass substrate.
[0012] In one optional embodiment, the width of the positioning plate is smaller than the width of the glass substrate, and when the conveyor belt drives the glass substrate to be inserted into the positioning groove, both ends of the glass substrate protrude from the positioning plate.
[0013] In one optional embodiment, there are two conveyor belts, which are respectively arranged on both sides of the turning device, and the horizontal height of the conveyor belts is the same as that of the transmission belt.
[0014] In one alternative embodiment, the flipping device, which is rotatably disposed in the middle of the conveyor belt, includes: a conveyor belt extending in a horizontal direction and driving the glass substrate to move. The drive roller is rotated between two conveyor belts; A plurality of positioning plates are evenly distributed along the circumferential direction of the outer wall of the drive roller, and every two positioning plates are arranged opposite each other. A positioning groove is formed between the two positioning plates, and a buffer is provided on the bottom wall of the positioning groove; The conveyor belt drives the glass substrate to be inserted into the positioning groove, and the glass substrate is deformed by the pressure buffer to make one end of the glass substrate located at the center line of the positioning groove. When the flipping assembly drives the glass substrate to flip, the lower end of the glass substrate is located at the center line of the positioning groove, and the buffer reduces the shaking amplitude of the glass substrate as it flips from one positioning plate sidewall to another positioning plate sidewall.
[0015] In one optional embodiment, the positioning groove is evenly distributed with a plurality of nozzles along its length, the nozzles being disposed on both sides of the buffer and connected to a compressed air pump. When the sidewall of the glass substrate is attached to a positioning plate, the nozzle near the sidewall of the other positioning plate blows air outward to remove static electricity from the outer wall of the glass substrate.
[0016] In one alternative embodiment, a cleaning strip is provided on the sidewall of a positioning plate, the cleaning strip abutting against the glass substrate; During the process of the drive roller rotating circumferentially to flip the glass substrate 180°, and the conveyor belt driving the glass substrate to detach from the positioning plate, the cleaning strip is suitable for scraping off the dust on the original bottom surface of the glass substrate.
[0017] Secondly, embodiments of this disclosure also provide a conveying method for a conveying device, the conveying method comprising: The conveyor belt drives the glass substrate to move horizontally toward the flipping device. The glass substrate moves onto the conveyor belt, and the conveyor belt drives the glass substrate to be horizontally inserted into the positioning groove. The glass substrate compression buffer deforms so that one end of the glass substrate is located at the center line of the positioning groove. When the flipping assembly drives the glass substrate to flip, the lower end of the glass substrate is located at the center line of the positioning groove, and the buffer reduces the shaking amplitude of the glass substrate as it flips from one positioning plate sidewall to another positioning plate sidewall.
[0018] The beneficial effects of this invention are that it provides a conveying device for glass substrate packaging. Through the arrangement of two opposing positioning plates, a positioning groove wider than the glass substrate, and a flipping assembly, the glass substrate is flipped during the flipping process. When the glass substrate is horizontally pressed against a buffer, the buffer is deformed by the glass substrate, thus limiting the movement of the glass substrate during flipping and improving its stability. After flipping the glass substrate 180°, the flipping assembly continues to rotate, and a cleaning strip abuts against the surface of the glass substrate to scrape away impurities.

[0029] Research has revealed that, in related technologies, the glass substrate, a thin sheet of glass with an extremely flat surface, is one of the key basic materials in the flat panel display industry. In the packaging process, the glass substrate needs to be horizontally transported by conveyor belt to a flipping device to complete a 180° flip for double-sided processing.
[0030] In related technologies, existing flipping devices typically insert a glass substrate into the positioning groove of the flipping device, and the flipping device rotates to flip the glass substrate.
[0031] However, when the glass substrate is inserted into the positioning groove, if the groove opening width is slightly larger than (≤1.1 times the glass substrate thickness) than the substrate thickness, friction scratches will occur on the glass substrate during insertion. If the positioning groove opening width is too large (e.g., 1.5 times the glass substrate thickness), displacement during flipping will increase the breakage rate. Additionally, the glass substrate easily attracts environmental dust during transport, requiring simultaneous cleaning during flipping.
[0032] Therefore, ensuring the stability of the glass substrate flipping process and the efficient removal of surface impurities are technical problems that urgently need to be solved in this field.
[0033] The defects in the above solutions and the reasons for their occurrence are the results of the inventors' practice and careful research. Therefore, the discovery process of the above problems and the solutions proposed in this disclosure should be considered as the inventors' contributions to this disclosure.
[0034] It should be noted that similar labels and letters in the following figures indicate similar items. Therefore, once an item is defined in one figure, it does not need to be further defined and explained in subsequent figures.
[0035] The following detailed description of some embodiments of the present invention is provided in conjunction with the accompanying drawings. Unless otherwise specified, the following embodiments and features can be combined with each other.
[0036] like Figures 1 to 6 As shown, at least one embodiment provides a conveying device for packaging a glass substrate 4, including: two conveyor belts 1, which are respectively disposed on both sides of a flipping device 2, and the horizontal height of the conveyor belts 1 is the same as the horizontal height of the conveyor belt 3. The conveyor belts 1 drive the glass substrate 4 to move horizontally to the flipping device 2, and the glass substrate 4 moves from the conveyor belts 1 to the conveyor belt 3, and the conveyor belt 3 drives the glass substrate 4 to continue moving towards the flipping device 2.
[0037] Reference Appendix Figure 2A flipping device 2 is rotatably disposed in the middle of the conveyor belt 1 for flipping the glass substrate 4. The flipping device 2 includes: a conveyor belt 3 extending horizontally and driving the glass substrate 4 to move; a flipping assembly 22 rotatably disposed in the middle of the conveyor belt 1 for supporting and cleaning the glass substrate 4; the flipping assembly 22 includes two opposing positioning plates 24 and a positioning groove 20 formed between them; a buffer member 21 fixed to the bottom wall of the positioning groove 20, the buffer member 21 being a flexible member with a cross-section including at least one recessed portion with an opening facing the glass substrate 4; after being squeezed and deformed by the glass substrate 4, the buffer member 21 is adapted to limit the glass substrate 4. A cleaning strip 26 is disposed on the side wall of the positioning plate 24; wherein, the conveyor belt 3 drives the end wall of the glass substrate 4 to move horizontally and insert it into the positioning groove 20 and squeeze the buffer member 21 to deform, so that one end of the glass substrate 4 is located at the center line of the positioning groove 20. When the flipping assembly 22 drives the glass substrate 4 to flip, the glass substrate 4 deforms by squeezing the buffer member 21 to suppress the shaking of the glass substrate 4 within the flipping assembly 22. After the flipping assembly 22 drives the glass substrate 4 to flip 180°, it continues to rotate. The cleaning strip 26 abuts against the surface of the glass substrate 4 to clean impurities, and the conveyor belt 3 drives the glass substrate 4 to disengage from the positioning groove 20. Through the arrangement of two opposing positioning plates 24, whose width is greater than the positioning groove 20 of the glass substrate 4, and the buffer member 21, when the glass substrate 4 is horizontally abutting against the buffer member 21, the buffer member 21 is squeezed and deformed by the glass substrate 4, thus pre-positioning the glass substrate 4 and reducing the shaking of the glass substrate 4 when the positioning plates 24 are flipped, thereby improving the stability of the glass substrate 4 during flipping. After the flipping assembly 22 flips the glass substrate 4 180°, it continues to rotate, and the cleaning strip 26 abuts against the surface of the glass substrate 4 to scrape away impurities from the surface of the glass substrate 4.
[0038] Continue to refer to the appendix Figure 2 The recessed portion of the buffer member 21 is V-shaped or U-shaped and its opening faces the glass substrate 4; the buffer member 21 is made of silicone. The cleaning strip 26 is made of silicone, and the pressure of its contact surface with the glass substrate 4 is ≤0.05N / mm²; the axis of the drive roller 23 of the flipping assembly 22 is located above the conveyor belt 3, and when the glass substrate 4 abuts against the buffer member 21, the positioning plate 24 forms an angle of 1°-5° with the horizontal plane.
[0039] The flipping assembly 22 includes a support frame disposed between two conveyor belts 1, a drive motor fixed to the side wall of the support frame, and a drive roller 23 fixed to the outer wall of the drive motor shaft. The drive motor is adapted to drive the drive roller 23 to rotate. There are eight positioning plates 24, with each pair of positioning plates 24 arranged opposite each other. The conveyor belt 3 drives the glass substrate 4 into the positioning groove 20, and the glass substrate 4 deforms under the pressure of the buffer member 21 so that one end of the glass substrate 4 is located at the center line of the positioning groove 20. When the flipping assembly 22 drives the glass substrate 4 to flip, the lower end of the glass substrate 4 is located at the center line of the positioning groove 20, and the buffer member 21 reduces the swaying amplitude of the glass substrate 4 as it flips from one side wall of the positioning plate 24 to the side wall of the other positioning plate 24. After the positioning plate 24 drives the glass substrate 4 to flip 180°, the flipping assembly 22 continues to rotate 2°-5° to bring the cleaning strip 26 into contact with the surface of the glass substrate 4 to clean impurities from the surface of the glass substrate 4.
[0040] Reference Appendix Figure 4 The glass substrate 4 is horizontally inserted into the positioning groove 20 until the glass substrate 4 abuts against the buffer member 21. The glass substrate 4 presses the buffer member 21 to bend and deform. The buffer member 21 is adapted to limit the glass substrate 4 so as to prevent the side wall of the glass substrate 4 from being completely attached to the side wall of a positioning plate 24.
[0041] Reference Appendix Figure 3 The positioning groove 20 is evenly distributed with several nozzles 25 along its length, with a spacing of 50-100mm between the nozzles 25. The output air pressure of the compressed air pump is 0.1-0.3 MPa. The nozzles 25 are located on both sides of the buffer 21 and are connected to the compressed air pump, which is an ionized compressed air generator. The airflow ejected by the nozzles 25 contains water vapor, which can remove static electricity generated by friction between the glass substrate 4 and the surface of the conveyor belt 1. When the sidewall of the glass substrate 4 is attached to one positioning plate 24, the nozzle 25 near the sidewall of the other positioning plate 24 blows air outward to remove static electricity from the outer wall of the glass substrate 4. When the glass substrate 4 is flipped from one positioning plate 24 to be attached to another positioning plate 24, the nozzle 25 on the other side of the buffer 21 blows air outward to clean the static electricity on the other side of the glass substrate 4.
[0042] Continue to refer to the appendix Figure 3 The opening width of the positioning groove 20 is not less than 1.5 times the thickness of the glass substrate 4.
[0043] A cleaning strip 26 is provided on the side wall of a positioning plate 24, and the cleaning strip 26 abuts against the glass substrate 4; the cleaning strip 26 is located on the side wall of the positioning plate 24 away from the buffer member 21. During the process of the drive roller 23 rotating circumferentially to flip the glass substrate 4 180° and the conveyor belt 3 driving the glass substrate 4 away from the positioning plate 24, the cleaning strip 26 is suitable for scraping away dust from the bottom surface of the glass substrate 4 before flipping. The cleaning strip 26 can remove impurities and dust from the original bottom wall of the glass substrate 4. Preferably, the cleaning strip 26 is a flexible component. Simultaneously, when the nozzle 25 blows air outward to clean the static electricity on the outer wall of the glass substrate 4, the high-pressure airflow from the nozzle 25 can also clean impurities remaining on the cleaning strip 26.
[0044] Appendix Figures 4 to 6 In the diagram, the direction of the arrow indicates the rotation direction of the drive roller 23.
[0045] Reference Appendix Figure 1 At least one embodiment provides a conveying device for packaging a glass substrate 4, comprising: The flipping device 2, rotatably disposed in the middle of the conveyor belt 1, includes: a conveyor belt 3 extending horizontally and driving the glass substrate 4 to move; a drive roller 23 rotatably disposed between two conveyor belts; a plurality of positioning plates 24, which are evenly distributed circumferentially along the outer wall of the drive roller 23, and each pair of positioning plates 24 are arranged opposite each other; a positioning groove 20 is formed between two positioning plates 24, and a buffer member 21 is provided on the bottom wall of the positioning groove 20; wherein, the conveyor belt 3 drives the glass substrate 4 to insert into the positioning groove 20, and the glass substrate 4 deforms by pressing the buffer member 21 so that one end of the glass substrate 4 is located at the center line of the positioning groove 20; when the flipping assembly 22 drives the glass substrate 4 to flip, the lower end of the glass substrate 4 is located at the center line of the positioning groove 20, and the buffer member 21 reduces the swaying amplitude of the glass substrate 4 from the side wall of one positioning plate 24 to the side wall of another positioning plate 24.
[0046] At least one embodiment provides a conveying method for a conveying device, the conveying method comprising: The conveyor belt 1 drives the glass substrate 4 to move horizontally toward the flipping device 2. The glass substrate 4 moves onto the conveyor belt 3, and the conveyor belt 3 drives the glass substrate 4 to be horizontally inserted into the positioning groove 20. The glass substrate 4 is deformed by the pressure buffer 21 so that one end of the glass substrate 4 is located at the center line of the positioning groove 20. When the flipping assembly 22 drives the glass substrate 4 to flip, the lower end of the glass substrate 4 is located at the center line of the positioning groove 20, and the buffer 21 reduces the shaking amplitude of the glass substrate 4 from the side wall of one positioning plate 24 to the side wall of another positioning plate 24.
[0047] In summary, refer to the appendix Figures 4 to 6The conveyor belt 1 drives the glass substrate 4 horizontally towards the flipping device 2. The glass substrate 4 moves horizontally onto the conveyor belt 3, which then drives the glass substrate 4 to insert into the positioning groove 20. The width of the positioning groove 20 is greater than 1.5 times the thickness of the glass substrate 4. This design prevents the glass substrate 4 from being scratched on its upper and lower sides by the sidewall of the positioning plate 24 during insertion into the positioning groove 20. Furthermore, during the contact between the glass substrate 4 and the buffer member 21, the buffer member 21 is designed to slow down the movement of the glass substrate 4, preventing hard contact between the glass substrate 4 and the bottom wall of the positioning groove 20. After the glass substrate 4 is limited by the buffer member 21, the drive roller 23 rotates to flip the glass substrate 4. When the glass substrate 4 is flipped to a near-vertical state, the bottom wall of the glass substrate 4 is bent and deformed by the pressure of the buffer member 21, and the buffer member 21 makes the bottom of the glass substrate 4 located at the center line of the positioning groove 20. Therefore, when the upper end of the glass substrate 4 flips from one positioning plate 24 to another positioning plate 24, its swaying amplitude is reduced, avoiding damage caused by excessive swaying amplitude of the glass substrate 4. At the same time, the nozzle 25 sprays air outward to clean the static electricity and floating dust on the surface of the glass substrate 4. After the glass substrate 4 is flipped, the conveyor belt 3 drives the glass substrate 4 away from the positioning plate 24. At this time, the drive roller 23 continues to flip, and the flipping angle is less than 3 degrees, so that the cleaning strip 26 abuts against the surface of the glass substrate 4. During the process of the glass substrate 4 leaving the positioning plate 24, the cleaning strip 26 scrapes away the impurities on the original bottom wall of the glass substrate 4.
