Description

Technical Field

[0001] This invention relates to the field of packaging equipment technology, and more specifically to a glass substrate packaging machine with a packaging box position correction mechanism. Background Technology

[0002] Glass substrates are the basic building blocks of LCD panels, and their cleanliness has a crucial impact on the entire LCD panel manufacturing process. As LCD panel technology continues to improve and display resolution continues to increase, the cleanliness requirements for glass substrates in the panel manufacturing process are becoming more stringent. After the glass substrates are processed, they need to be packaged in boxes to protect them during subsequent transportation and storage.

[0003] Currently, to improve the packaging efficiency of glass substrates, automated packaging machines are commonly used. During operation, these machines utilize two conveyors to transport the glass substrates and packaging boxes separately. A robotic arm and a positioning mechanism at the free end of the robotic arm transfer the glass substrates into the packaging boxes, thus achieving the effect of packaging the glass substrates using the packaging boxes. The packaging boxes, after being packaged, can then be transported to the next process via a separate conveyor, improving packaging efficiency. However, in actual use, the following drawbacks still exist:

[0004] When the conveyor transports the packaging box, the packaging box is prone to shifting on the conveyor. Furthermore, when the packaging box is placed on top of the conveyor, the stability of the robotic arm when placing the glass substrate into the packaging box is insufficient. This can easily lead to the placement deviation of the glass substrate, which is not conducive to the packaging operation of the glass substrate.

[0005] Therefore, this application proposes a glass substrate packaging machine with a packaging box position correction mechanism. Summary of the Invention

[0006] To address the shortcomings of existing technologies, this invention provides a glass substrate packaging machine with a packaging box position correction mechanism, which solves the problems mentioned in the background art.

[0007] To achieve the above objectives, the present invention provides the following technical solution:

[0008] A glass substrate packaging machine with a packaging box position correction mechanism includes a base, a first conveyor for conveying glass substrates is mounted on the top of the base, and a second conveyor is symmetrically mounted on the top of the base and on both sides of the first conveyor. The second conveyor is used to convey packaging boxes. The second conveyor includes a conveyor frame fixedly mounted on the top of the base, and multiple conveyor rollers are rotatably connected in a horizontal linear array on the conveyor frame.

A pressure sensor is fixedly installed on the top of the connecting plate and in contact with the mounting base. Vertical support columns are symmetrically fixed on the top of the base block and on both sides of the connecting plate. When the support columns are in contact with the mounting base, the two spring telescopic rods are in their natural state. A support plate is fixedly installed in a horizontal linear array at the bottom position of the limiting block on the side away from the telescopic rod. The top of the support plate is located below the conveyor roller, and the support plate can be inserted between the opposite sides of two adjacent conveyor rollers.

[0014] Furthermore: both sides of the top of the fixed frame are hinged with horizontal hinge shafts, and the bottom block is hinged to the top of the fixed frame through the hinge shafts. The fixed frame is equipped with a drive mechanism that acts on the two hinge shafts, which is used to make the two hinge shafts rotate in opposite directions or stop rotating on the fixed frame.

[0015] Furthermore: the drive mechanism includes a horizontally rotatable rod mounted on a fixed frame. The two ends of the rod are connected to two hinge shafts respectively through a bevel gear assembly. A motor is fixedly mounted on the fixed frame, and the output shaft of the motor is connected to the rod through a bevel gear assembly.

[0016] Furthermore: a mounting bracket is fixedly mounted on the top of the mounting block, and the mounting block is movably sleeved on the connecting rod through the bracket. A contact block that can be connected to the mounting block is fixedly mounted on the bottom of the connecting rod. A connecting spring is sleeved on the outside of the connecting rod, and the two ends of the connecting spring are respectively connected to the contact block and the bracket. A pressure sensor 2 that contacts the bracket is fixedly mounted on the top of the contact block.

[0017] Furthermore: upright plates are symmetrically installed on the top of the mounting block and on both sides of the horizontal plate. A hinge plate is hinged to the bottom of the upright plate.

[0019] Furthermore: both upright plates are slidably mounted on the bottom of the mounting block along the mounting plate direction, and a bidirectional threaded rod that is threadedly connected to both upright plates is rotatably mounted on the mounting block, and a motor connected to the bidirectional threaded rod is fixedly mounted on the mounting block.

[0020] This invention provides a glass substrate packaging machine with a packaging box position correction mechanism. Compared with the prior art, it has the following advantages:

[0021] 1. When packaging glass substrates, the design of the correction and positioning component can correct and position the packaging boxes conveyed on the second conveyor during the packaging operation. This corrects any misaligned packaging boxes on the second conveyor and positions the packaging boxes when the robotic arm places the glass substrates into them, improving stability and effectively preventing deviations when placing the glass substrates. This is beneficial for the packaging operation of glass substrates.

[0022] 2. By setting the bottom block to be hinged to the top of the fixed frame via the hinge shaft, when the components of the straightening and positioning assembly are damaged, the two hinge shafts are rotated in opposite directions on the fixed frame by the drive mechanism, thereby causing the two mounting seats to move away from each other in an arc through the bottom block, so that the telescopic rod two is in a horizontal position. At this time, the tray is located below the conveyor frame, which facilitates the disassembly of the straightening and positioning assembly and pulls it out from below the conveyor frame, making it convenient to disassemble, repair or replace the straightening and positioning assembly.

[0023] 3. By setting up an installation frame including an installation plate, telescopic rod four, a base plate, and a drive rod five, when unloading unqualified packaging boxes, the drive rod five causes the base plate to move along the telescopic rod four towards the installation plate, which in turn causes the horizontal plate to move inward toward the two vertical plates, thereby increasing the height of the glass substrate and achieving a clearance effect. This effectively avoids friction between the material and the packaging box during unloading. Attached Figure Description

[0035] 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.

[0036] Example 1

[0037] To address the technical problems in the background section, a glass substrate packaging machine with a packaging box position correction mechanism is provided as follows:

[0038] Combination Figures 1-9 As shown, the glass substrate packaging machine with a packaging box position correction mechanism provided by the present invention includes a base 1, a conveyor 11 for conveying glass substrates is installed on the top of the base 1, and a second conveyor 12 is symmetrically installed on the top of the base 1 and on both sides of the first conveyor 11. The second conveyor 12 is used to convey packaging boxes. The second conveyor 12 includes a conveyor frame 121 fixedly installed on the top of the base 1. Multiple conveyor rollers 122 are rotatably connected in a horizontal linear array on the conveyor frame 121.

[0039] A robotic arm 13 is symmetrically fixedly installed on the top of the base 1 and between conveyor 11 and conveyor 2 12. A connecting rod 14 is fixedly installed on the free end of the robotic arm 13. An installation block 2 is installed on the connecting rod 14. An installation frame 21 is installed at the bottom of the installation block 2. A positioning mechanism 3 is installed at the bottom of the installation frame 21 for positioning the glass mechanism. The positioning mechanism 3 includes a horizontal plate 31 fixedly installed at the bottom of the installation frame 21. Several vacuum suction cups 32 are fixedly installed at the bottom of the horizontal plate 31. The top of the multiple vacuum suction cups 32 is connected to the same air pipe 33. The other end of the air pipe 33 is connected to an external negative pressure pump.

[0040] Correction and positioning components 4 are installed on the base 1 and below both ends of the second conveyor 12. The ends of the correction and positioning components 4 extend to the top of the second conveyor 12. The four correction and positioning components 4 correspond one-to-one with the four robotic arms 13. The correction and positioning components 4 are used to correct and position the packaging boxes conveyed on the second conveyor 12.

[0041] During the packaging of glass substrates, the glass substrates to be packaged are transported by conveyor 11, and the packaging boxes are transported by two conveyors 12. During this process, the packaging boxes are located on top of multiple conveyor rollers 122. As the multiple conveyor rollers 122 rotate on the conveyor frame 121, they transport the packaging boxes. During this process, through the cooperation of four robotic arms 13 and the positioning mechanism 3 mounted on the robotic arms 13, multiple vacuum suction cups 32 are made to adhere to the glass substrate. An external negative pressure pump is controlled to extract air from the vent pipe 33, creating a vacuum state inside the multiple vacuum suction cups 32. The multiple vacuum suction cups 32 then adhere to the glass substrate. The substrate is positioned, and with the cooperation of the robotic arm 13, the glass substrate on conveyor 11 can be placed into the packaging box on conveyor 12. Through the design of the correction and positioning component 4, the packaging box conveyed on conveyor 12 can be corrected and positioned during the glass substrate packaging operation. This corrects any deviation in the packaging box conveyed on conveyor 12 and positions the packaging box when the robotic arm 13 places the glass substrate into it, improving stability and effectively avoiding deviations when placing the glass substrate, thus facilitating the glass substrate packaging operation.

[0042] In this embodiment, the correction and positioning component 4 is fixedly installed on the top of the base 1 and below the conveyor frame 121. A fixing frame 41 is fixedly installed on the top of the base 1 by screws. Connecting blocks 42 are installed on the top of the fixing frame 41 and on both sides of the conveyor frame 121. A mounting seat 43 is installed on the top of the connecting blocks 42. A mounting groove 431 is opened on the side of the mounting seat 43 near the conveyor frame 121. A horizontal telescopic rod 432 is symmetrically fixedly installed on the mounting seat 43 and in the mounting groove 431. Limiting blocks 433 are fixedly installed at the ends of the two telescopic rods 432. A drive rod 434 connected to the limiting block 433 is fixedly installed on the mounting seat 43 and in the mounting groove 431. A limiting plate 44 perpendicular to the limiting block 433 is fixedly installed on the side of the limiting block 433 away from the telescopic rod 432. The side of the limiting block 433 away from the telescopic rod 432 is along the limiting plate. A straightening plate 45 is slidably installed in the 44 direction. An electromagnetic slider 46 connected to the straightening plate 45 is fixedly installed on the limiting block 433. In use, when positioning the packaging box conveyed on the second conveyor 12, when the packaging box is conveyed between the two limiting blocks 433, the two drive rods 434 are controlled to bring the limiting blocks 433 closer to each other, so that both limiting blocks 433 are in contact with the packaging box. At this time, the straightening plate 45 is slid towards the limiting plate 44 by the electromagnetic slider 46, so that both straightening plates 45 are in contact with the packaging box. When the two straightening plates 45 move towards the limiting plate 44, they can push the packaging box closer to the two limiting plates 44 and make contact with both limiting plates 44, thereby straightening the packaging box and positioning it directly above the second conveyor 12. In this way, the two limiting blocks 433, the two limiting plates 44, and the two straightening plates 45 are all in contact, thus achieving the positioning effect of the packaging box.

[0043] In this embodiment, the correcting plate 45 includes a movable frame 451 slidably mounted on one side of the limiting block 433 along the direction of the limiting plate 44. An electromagnetic slider 46 is connected to the movable frame 451. A plate 452 is hinged to the movable frame 451. A motor 453 connected to the plate 452 is fixedly mounted on the movable frame 451. By configuring the correcting plate 45 to include the movable frame 451, the plate 452, and the motor 453, during the correction and positioning of the packaging box, while the conveyor 12 is conveying the packaging box, the motor 453 causes the plate 452 to rotate on the movable frame 451, so that the free end of the plate 452 is located on the side of the movable frame 451 away from the limiting plate 44 and parallel to the limiting block 433. This controls the rotation of the two... Drive rod 434 brings the limiting blocks 433 closer together, so that both limiting plates 44 extend above the conveyor roller 122. When conveyor 12 transports the packaging box, it can directly contact the two limiting plates 44. Then, motor 453 makes the plate 452 rotate on the moving frame 451, so that the plate 452 is parallel to the limiting blocks 433. Control the two drive rods 434 to bring the limiting blocks 433 closer together, so that both limiting blocks 433 are in contact with the packaging box. The electromagnetic slider 46 makes the straightening plate 45 slide towards the limiting plate 44, so that both straightening plates 45 are in contact with the packaging box. This can straighten and position the packaging box, reducing the friction between the packaging box and the conveyor roller 122 when it moves horizontally at the top of conveyor 12.

[0044] Example 2

[0045] like Figures 1-9 As shown, based on the above embodiments, this embodiment further provides the following:

[0046] In this embodiment, the connecting block 42 includes a base block 421 mounted on top of the fixing frame 41. Two vertical telescopic rods 422 are fixedly mounted on the top of the base block 421. A connecting plate 423 is fixedly connected to the top of the two telescopic rods 422. A driving rod 424 connected to the connecting plate 423 is fixedly mounted on the top of the base block 421. Spring telescopic rods 425 are symmetrically fixed on the top of the connecting plate 423. The mounting base 43 is fixedly connected to the top of the two spring telescopic rods 425. A pressure sensor 427 in contact with the mounting base 43 is fixedly mounted on the top of the connecting plate 423. Device 427 is connected to a PLC control system. The PLC control system has a preset weight threshold for the packaging box. Vertical support columns 428 are symmetrically fixed on the top of the base block 421 and on both sides of the connecting plate 423. When the support columns 428 contact the mounting base 43, both spring telescopic rods 425 are in their natural state. A tray 426 is fixedly mounted in a horizontal linear array at the bottom of the limiting block 433 on the side away from the telescopic rod 432. The top of the tray 426 is located below the conveyor roller 122, and the tray 426 can be inserted between the opposite sides of two adjacent conveyor rollers 122. In use, the two... When the limiting block 433, the two limiting plates 44, and the two straightening plates 45 are all in contact to straighten and position the packaging box, the multiple pallets 426 are all located at the bottom of the packaging box. At this time, the two drive rods 424 work, causing the two connecting plates 423 to move upward synchronously along the telescopic rods 422, thereby driving the mounting base 43 to move upward. Through the limiting block 433, the pallets 426 are driven upward, thus achieving the effect of lifting the packaging box upward. At this time, the mounting base 43 is not in contact with the support column 428. The mounting base 43 applies pressure to the two spring telescopic rods 425 and the pressure sensor 427. When a downward pressure is applied, the force detection signal of pressure sensor 427 changes. Furthermore, as the weight of the packaging box increases, the downward pressure on pressure sensor 427 increases again, causing its force detection signal to change once more. During this process, pressure sensor 427 feeds back the detection signal to the PLC control system, achieving a gravity detection effect. By measuring the difference between two gravity detection values, the weight of the packaging box can be detected, thus achieving a quality inspection of the packaging box. This helps prevent damage or missing parts from compromising the protection of the glass substrate after packaging.

[0047] In this embodiment, both sides of the top of the fixed frame 41 are hinged with horizontally oriented hinge shafts 411. The bottom block 421 is hinged to the top of the fixed frame 41 via the hinge shafts 411. A drive mechanism 47 acting on the two hinge shafts 411 is installed on the fixed frame 41, which is used to make the two hinge shafts 411 rotate in opposite directions or stop rotating on the fixed frame 41. It is worth noting that when the telescopic rod 422 is horizontal, the pallet 426 is located below the conveyor frame 121. By setting the bottom block 421 to... The hinge shaft 411 is hinged to the top of the fixed frame 41. When the components of the straightening and positioning assembly 4 are damaged, the two hinge shafts 411 are rotated in opposite directions on the fixed frame 41 by the drive mechanism 47. This causes the two mounting seats 43 to move away from each other in an arc through the bottom block 421, so that the telescopic rod 422 is horizontal. At this time, the support plate 426 is located below the conveyor frame 121, which facilitates the disassembly of the straightening and positioning assembly 4 and pulls it out from below the conveyor frame 121, making it convenient to disassemble, repair or replace the straightening and positioning assembly 4.

[0048] In this embodiment, the drive mechanism 47 includes a horizontally rotatable rod 471 mounted on a fixed frame 41. The two ends of the rod 471 are connected to two hinge shafts 411 respectively via bevel gear assembly 472. The two sets of bevel gear assembly 472 are symmetrically arranged. A motor 473 is fixedly mounted on the fixed frame 41. The output shaft of the motor 473 is connected to the rod 471 via bevel gear assembly 474. In use, the motor 473 is controlled to work, and the output shaft of the motor 473 rotates, which drives the rod 471 to rotate on the fixed frame 41 via the bevel gear assembly 474. Thus, the two sets of bevel gear assembly 472 drive the two hinge shafts 411 to rotate on the fixed frame 41. Since the two sets of bevel gear assembly 472 are symmetrically arranged, the two hinge shafts 411 can rotate in opposite directions on the fixed frame 41, which is convenient for control.

[0049] Example 3

[0050] like Figures 1-9 As shown, based on the above embodiments, this embodiment further provides the following:

[0051] In this embodiment, a mounting bracket 5 is fixedly mounted on the top of the mounting block 2. The mounting block 2 is movably sleeved on the connecting rod 14 via the bracket 5. A contact block 141, which can be connected to the mounting block 2, is fixedly mounted on the bottom of the connecting rod 14. A connecting spring 142 is sleeved on the outside of the connecting rod 14. The two ends of the connecting spring 142 are respectively connected to the contact block 141 and the bracket 5. A pressure sensor 143, which contacts the bracket 5, is fixedly mounted on the top of the contact block 141. The pressure sensor 143 is communicatively connected to the PLC control system. A glass substrate is pre-installed in the PLC control system. The weight threshold of the plate is determined by the design of pressure sensor 143. During use, the mechanical arm 13 and the positioning mechanism 3 work together to lift the glass substrate upwards without contacting the conveyor 11. Under the gravity of the glass substrate, the bracket 5 slides downwards on the connecting rod 14 through the mounting block 2. During this process, the connecting spring 142 deforms, and the force detection signal of pressure sensor 143 changes. The detection signal is then fed back to the PLC control system, thereby achieving the effect of weight detection of the glass substrate and realizing the effect of re-inspection of the glass substrate before it is placed into the packaging box.

[0052] In this embodiment, upright plates 6 are symmetrically installed on the top of the mounting block 2 and on both sides of the horizontal plate 31. A hinge plate 61 is hinged to the bottom of the upright plate 6. A drive rod 62, hinged to the hinge plate 6 and connected to the hinge plate 61, is mounted on the upright plate 6. A mounting cavity 611 is formed at the free end of the hinge plate 61. Telescopic rods 612 are symmetrically fixedly installed on the hinge plate 61 and within the mounting cavity 611. The telescopic ends of the two telescopic rods 612 extend to the outside of the mounting cavity 611 and are fixedly mounted with clamping blocks 613. The hinge plate 61... Furthermore, a drive rod 614 connected to the clamping block 613 is fixedly installed inside the mounting cavity 611. Clamping plates 615 are rotatably installed on the bottom positions of the two clamping blocks 613 on their sides. By setting up the upright plate 6, hinge plate 61, and clamping plate 615, when the weight of the packaging box is not within the preset weight threshold range in the PLC control system during weight detection, the robotic arm 13 positions the mounting block 2 directly above the packaging box, and positions the two upright plates 6 respectively on the packaging box. On both sides, at this time, the two drive rods 62 are controlled to rotate the two hinge plates 61 on the two vertical plates 6 respectively, so that the free ends of the two hinge plates 61 approach each other. With the cooperation of the drive rod 614 causing the clamping block 613 to move along the two telescopic rods 612, the two clamping plates 615 respectively come into contact with the outside of the two packaging boxes, thereby clamping and positioning the packaging boxes. At this time, with the cooperation of the robotic arm 13, the unqualified packaging boxes on the conveyor 12 can be unloaded. By setting the clamping plate 615 and the clamping block 613 to be rotatably connected, and by the cooperation of the drive rod three 62 and the drive rod four 614, when the two clamping plates 615 respectively abut against the outside of the two packaging boxes, the contact area between the clamping plates 615 and the packaging boxes is increased, thereby improving the clamping and positioning effect of the packaging boxes; it is worth noting that: a waste collection area is set on the outside of the base 1. When the packaging box or glass substrate is unqualified, the robotic arm 13 unloads the packaging box or glass substrate into the waste collection area on the outside of the base 1.

[0053] In this embodiment, the mounting frame 21 includes a mounting plate 211 fixedly mounted on the bottom of the mounting block 2. Vertical telescopic rods 212 are symmetrically fixedly mounted on the bottom of the mounting plate 211. A base plate 213 is fixedly mounted on the bottom of the two telescopic rods 212. A horizontal plate 31 is fixedly connected to the base plate 213. A drive rod 214 connected to the base plate 213 is fixedly mounted on the bottom of the mounting plate 211. By configuring the mounting frame 21 to include the mounting plate 211, telescopic rods 212, base plate 213, and drive rod 214, when unloading defective packaging boxes, the drive rod 214 causes the base plate 213 to move along the telescopic rods 212 towards the mounting plate 211, thereby driving the horizontal plate 31 towards the two... The inner side of the upright plate 6 is displaced, thereby increasing the height of the glass substrate and achieving a clearance effect, effectively avoiding friction between the plate and the packaging box when unloading the packaging box. It is worth noting that when positioning the glass substrate, the bottom plate 213 is moved away from the mounting plate 211 along the telescopic rod 212 by the drive rod 214, so that the horizontal plate 31 is located outside the two upright plates 6. Then, the two hinge plates 61 are rotated on the two upright plates 6 by the two drive rods 62, so that the two hinge plates 61 are both horizontal. Thus, when the positioning mechanism 3 is used to position the glass substrate, friction between the hinge plates 61, the clamping block 613, the clamping plate 615 and the glass substrate is effectively avoided.

[0054] In this embodiment, both upright plates 6 are slidably mounted on the bottom of the mounting block 2 along the direction of the mounting plate 211. A bidirectional threaded rod 22, which is threadedly connected to both upright plates 6, is rotatably mounted on the mounting block 2. A motor 23, which is connected to the bidirectional threaded rod 22, is fixedly mounted on the mounting block 2. In use, controlling the motor 23 to work will drive the bidirectional threaded rod 22 to rotate on the mounting block 2, thereby causing the two upright plates 6 to move closer or further apart at the bottom of the mounting block 2. The distance between the two upright plates 6 can be adjusted. Thus, when clamping and positioning packaging boxes of different sizes, the distance between the two upright plates 6 can be adjusted to adjust the distance between the two clamping blocks 613, so as to facilitate the clamping and positioning of packaging boxes of different sizes, thereby improving the clamping and positioning effect of packaging boxes of different sizes and improving applicability.
