After the glass substrate is processed, it needs to be placed in a packaging box for packaging, so as to protect the glass substrate during transportation and storage in the later stage.

[0003] At present, in order to improve the packaging efficiency of glass substrates, automatic packaging is usually performed by an automatic packaging machine. When the automatic packaging machine is working, two sets of conveyors are used to transport the glass substrates and the packaging boxes respectively, and the glass substrates are transferred and placed in the packaging boxes by a mechanical arm and a positioning mechanism installed at the free end of the mechanical arm, so as to achieve the effect of packaging the glass substrates by the packaging boxes, so that the packaging boxes after packaging the glass substrates can be transported to the next process by the conveyor for transporting the packaging boxes, thereby improving the packaging efficiency. However, in actual use, there are still the following defects:

The positioning mechanism 3 includes a horizontal plate 31 fixedly installed at the bottom of the mounting frame 21. A plurality of vacuum suction cups 32 are fixedly installed at the bottom of the horizontal plate 31. The tops of the plurality of vacuum suction cups 32 are connected to the same ventilation pipe 33, and the other end of the ventilation pipe 33 is connected to an external negative pressure pump;

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

[0041] When packaging the glass substrates, the glass substrates to be packaged are transported by the conveyor 11, and the packaging boxes are transported by the two conveyor 2s 12. During this period, the packaging boxes are located on the top of the plurality of conveyor rollers 122, and the plurality of conveyor rollers 122 transport the packaging boxes when rotating on the conveyor frame 121. During this period, the plurality of vacuum suction cups 32 are all attached to the glass substrates through the cooperation of the four mechanical arms 13 and the positioning mechanism 3 installed on the mechanical arms 13, and the external negative pressure pump is controlled to draw out the air in the ventilation pipe 33 to the outside, so that a vacuum state is formed in the plurality of vacuum suction cups 32, and the glass substrates are attached to the plurality of vacuum suction cups 32. The substrate is positioned, and with the cooperation of the robot arm 13, the glass substrate on the conveyor 11 can be placed in the packaging box on the conveyor 2 12. Through the design of the correction and positioning component 4, when the glass substrate is packaged, the packaging box transported on the conveyor 2 12 can be corrected and positioned by the correction and positioning component 4, so that the packaging box that is offset during transportation on the conveyor 2 12 can be corrected, and when the robot arm 13 places the glass substrate into the packaging box, the packaging box is positioned to improve stability, effectively avoid deviation when placing the glass substrate, and thus facilitate the packaging operation of the glass substrate.

[0042] In this embodiment, the correction and positioning component 4 is fixedly mounted on the top of the base 1 and is located below the conveying frame 121. A fixing frame 41 is fixedly mounted 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 conveying frame 121. A mounting seat 43 is installed on the top of the connecting block 42. A mounting groove 431 is provided on the side of the mounting seat 43 close to the conveying frame 121. A horizontal telescopic rod 432 is symmetrically fixedly mounted on the mounting seat 43 and in the mounting groove 431. Limiting blocks 433 are fixedly mounted at the ends of the two telescopic rods 432. A driving rod 434 connected to the limiting block 433 is fixedly mounted on the mounting seat 43 and in the mounting groove 431. A limiting plate 44 perpendicular to the limiting block 433 is fixedly mounted on the side of the limiting block 433 away from the telescopic rod 432. The limiting plate 44 is fixedly mounted on the side of the limiting block 433 away from the telescopic rod 432. A correction plate 45 is slidably installed in the direction of 44, and an electromagnetic slider 46 connected to the correction plate 45 is fixedly installed on the limit block 433. When in use, when positioning the package box transported on the conveyor 2 12, when the package box is transported between the two limit blocks 433, the two driving rods 1 434 are controlled to make the limit blocks 433 approach each other so that the two limit blocks 433 are in contact with the package box. At this time, the correction plate 45 is slid toward the limit plate 44 by the electromagnetic slider 46, so that the two correction plates 45 are in contact with the package box. When the two correction plates 45 are displaced toward the limit plate 44, the package box can be pushed toward the two limit plates 44 and in contact with the two limit plates 44, thereby correcting the package box so that the package box is located directly above the conveyor 2 12, and the two limit blocks 433, the two limit plates 44 and the two correction plates 45 are in contact, thereby achieving the positioning effect of the package box.

[0043] In this embodiment, the correction plate 45 includes a moving frame 451 which is slidably installed on one side of the limit block 433 along the direction of the limit plate 44, the electromagnetic slider 46 is connected to the moving frame 451, a plate body 452 is hinged on the moving frame 451, and a motor 453 connected to the plate body 452 is fixedly installed on the moving frame 451. By setting the correction plate 45 to include the moving frame 451, the plate body 452 and the motor 453, when the packaging box is corrected and positioned, during the transportation of the packaging box by the conveyor 12, the plate body 452 is rotated on the moving frame 451 by the motor 453, so that the free end of the plate body 452 is located on the side of the moving frame 451 away from the limit plate 44, and is parallel to the limit block 433, and the two The driving rod 1 434 makes the limit blocks 433 approach each other, so that the two limit plates 44 are extended to the top of the conveying roller 122. When the conveyor 2 12 transports the packaging box, it can directly contact the two limit plates 44, and then the motor 1 453 is used to rotate the plate body 452 on the movable frame 451, so that the plate body 452 is parallel to the limit blocks 433, and the two driving rods 1 434 are controlled to make the limit blocks 433 approach each other, so that the two limit blocks 433 are in contact with the packaging box; the electromagnetic slider 46 is used to make the correction plate 45 slide in the direction of the limit plate 44, so that the two correction plates 45 are in contact with the packaging box, so that the packaging box can be corrected and positioned, thereby reducing the friction between the packaging box and the conveying roller 122 when it translates at the top of the conveyor 2 12.

[0044] Embodiment 2

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

[0046] In this embodiment, the connecting block 42 includes a bottom block 421 mounted on the top of the fixing frame 41, two telescopic rods 422 are fixedly mounted on the top of the bottom block 421, and the tops of the two telescopic rods 422 are fixedly connected with a connecting plate 423, a driving rod 424 connected to the connecting plate 423 is fixedly mounted on the top of the bottom block 421, and spring telescopic rods 425 are symmetrically fixed on the top of the connecting plate 423. The mounting seat 43 is fixedly connected to the tops of the two spring telescopic rods 425, and a pressure sensor 427 in contact with the mounting seat 43 is fixedly mounted on the top of the connecting plate 423. The device 427 is communicatively connected to a PLC control system, in which a weight threshold of the packaging box is preset. A vertical support column 428 is symmetrically fixed on the top of the bottom block 421 and on both sides of the connecting plate 423. When the support column 428 is in contact with the mounting seat 43, the two spring telescopic rods 425 are in a natural state, and a support plate 426 is fixedly installed in a horizontal linear array at the bottom position of the limit block 433 away from the telescopic rod 432. The top of the support plate 426 is located below the conveying roller 122, and the support plate 426 can be inserted between the opposite sides of two adjacent conveying rollers 122. When in use, the two When the limit blocks 433, the two limit plates 44 and the two correction plates 45 are all in contact to correct the positioning of the packaging box, at this time, the multiple support plates 426 are all located at the bottom of the packaging box. At this time, the two driving rods 424 are carried to work, so that the two connecting plates 423 are synchronously moved upward along the telescopic rods 422, thereby driving the mounting seat 43 to move upward, and the support plates 426 are driven to move upward by the limit blocks 433, so as to achieve the effect of lifting the packaging box upward. At this time, the mounting seat 43 is not in contact with the support column 428, and the mounting seat 43 exerts pressure on the two spring telescopic rods 425 and the pressure sensor 1 427. The downward force causes the force detection signal of the pressure sensor 427 to change, and under the weight of the packaging box, the downward force on the pressure sensor 427 is further increased, and the force detection signal of the pressure sensor 427 changes again. During this period, the pressure sensor 427 feeds back the detection signal to the PLC control system to achieve the gravity detection effect, so that the weight of the packaging box can be detected through the difference between the two gravity detection values, thereby achieving the quality detection effect of the packaging box to avoid the situation where the packaging box is missing or damaged, which reduces the protection effect of the glass substrate after packaging.

[0047] In this embodiment, both sides of the top of the fixed frame 41 are hinged with horizontal hinge shafts 411, and the bottom block 421 is hinged to the top of the fixed frame 41 through the hinge shaft 411. A driving 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 support plate 426 is located below the conveying frame 121, and the bottom block 421 is set to drive the two hinge shafts 411 to rotate in opposite directions or stop rotating. The hinge shaft 411 is hinged on the top of the fixed frame 41. When the parts of the correction and positioning assembly 4 are damaged, the two hinge shafts 411 are rotated in opposite directions on the fixed frame 41 through the driving mechanism 47, so that the two mounting seats 43 are moved 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 conveying frame 121, so that the correction and positioning assembly 4 can be disassembled and pulled out from the bottom of the conveying frame 121, which is convenient for disassembly, maintenance or replacement of the correction and positioning assembly 4.

[0048] In this embodiment, the driving mechanism 47 includes a rotating rod 471 which is horizontal and rotatably mounted on the fixed frame 41. The two ends of the rotating rod 471 are respectively connected to the two hinge shafts 411 through a bevel gear assembly 472. The two sets of bevel gear assemblies 472 are symmetrically arranged. A motor 473 is fixedly installed on the fixed frame 41. The output shaft of the motor 473 is connected to the rotating rod 471 through a bevel gear assembly 474. When in use, the motor 473 is controlled to work, and the output shaft of the motor 473 rotates to drive the rotating rod 471 to rotate on the fixed frame 41 through the bevel gear assembly 474, thereby driving the two hinge shafts 411 to rotate on the fixed frame 41 through the two sets of bevel gear assemblies 472. Since the two sets of bevel gear assemblies 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] Embodiment 3

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

[0051] In this embodiment, the mounting bracket 5 is fixed on the top of the mounting block 2, and the mounting block 2 is movably sleeved on the connecting rod 14 through the bracket 5. A contact block 141 that can be connected to the mounting block 2 is fixedly installed at 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 in contact with the bracket 5 is fixedly installed on the top of the contact block 141. The pressure sensor 143 is connected to the PLC control system for communication. The PLC control system is preset with a glass base The weight threshold of the plate is determined by the design of the pressure sensor 143. When in use, the glass substrate is lifted upward by the cooperation of the mechanical arm 13 and the positioning mechanism 3 so that it does not contact the conveyor 11. Under the action of the gravity of the glass substrate, the bracket 5 is made to slide downward on the connecting rod 14 through the mounting block 2. During this period, the connecting spring 142 is deformed, and the force detection signal of the pressure sensor 143 changes, and the detection signal is fed back to the PLC control system, thereby realizing the weight detection effect of the glass substrate and realizing the re-inspection effect of the glass substrate before placing it in the packaging box.

[0052] In this embodiment, the top of the mounting block 2 and the two sides of the horizontal plate 31 are symmetrically installed with a vertical plate 6, the bottom of the vertical plate 6 is hinged with a hinged plate 61, and the vertical plate 6 is hinged with a driving rod 3 62 hinged with the hinged plate 61. The free end of the hinged plate 61 is provided with a mounting cavity 611, and the hinged plate 61 is symmetrically fixed with a telescopic rod 3 612 in the mounting cavity 611. The telescopic ends of the two telescopic rods 3 612 extend to the outside of the mounting cavity 611 and are fixedly installed with a clamping block 613. A driving rod 614 connected to the clamping block 613 is fixedly installed in the installation cavity 611, and a clamping plate 615 is rotatably installed at the bottom position of the two clamping blocks 613 on the side close to each other. By setting the vertical plate 6, the hinged plate 61 and the clamping plate 615, when the weight of the packaging box is detected, when the weight of the packaging box is not within the preset packaging box weight threshold range in the PLC control system, the mechanical arm 13 is used to make the installation block 2 located directly above the packaging box, and the two vertical plates 6 are respectively located on the packaging box. On both sides of the two sides, at this time, the two driving rods 3 62 are controlled to make the two hinged plates 61 rotate on the two vertical plates 6 respectively, so that the free ends of the two hinged plates 61 are close to each other, and the clamping block 613 is displaced along the two telescopic rods 3 612 by the driving rod 4 614, so that the two clamping plates 615 are respectively in contact with the outer sides of the two packaging boxes, so that the packaging boxes can be clamped and positioned. At this time, the unqualified packaging boxes on the conveyor 2 12 can be unloaded through the cooperation of the mechanical arm 13; By setting the clamping plate 615 and the clamping block 613 to be rotatably connected, and through the cooperation of the driving rod three 62 and the driving rod four 614, when the two clamping plates 615 are respectively in contact with the outer sides 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; among them, it is worth mentioning that: a waste collection area is set on the outside of the base 1. When the packaging box or the glass substrate is unqualified, the packaging box or the glass substrate is unloaded to the waste collection area outside the base 1 through the robot arm 13.

[0053] In this embodiment, the mounting frame 21 includes a mounting plate 211 fixedly mounted on the bottom of the mounting block 2, and a vertical telescopic rod 212 is symmetrically fixedly mounted on the bottom of the mounting plate 211, and a bottom plate 213 is fixedly mounted on the bottom of the two telescopic rods 212. The cross plate 31 is fixedly connected to the bottom plate 213, and a driving rod 214 connected to the bottom plate 213 is fixedly mounted on the bottom of the mounting plate 211. By setting the mounting frame 21 to include the mounting plate 211, the telescopic rod 212, the bottom plate 213 and the driving rod 214, when unqualified packaging boxes are unloaded, the bottom plate 213 is displaced toward the mounting plate 211 along the telescopic rod 212 through the driving rod 214, and the cross plate 31 can be driven to move to the two The vertical plate 6 is displaced inwardly, thereby increasing the height of the glass substrate, achieving a giving way effect, and effectively avoiding the friction between the packaging box and the packaging box when unloading the material; it is worth noting that: when positioning the glass substrate, the bottom plate 213 is displaced away from the mounting plate 211 along the telescopic rod four 212 by driving the fifth rod 214, so that the cross plate 31 can be located on the outside of the two vertical plates 6, and then the two hinged plates 61 are rotated on the two vertical plates 6 by the two driving rods three 62, so that the two hinged plates 61 are both horizontal, so that when the positioning mechanism 3 is used to position the glass substrate, the friction between the hinged plate 61, the clamping block 613 and the clamping plate 615 and the glass substrate is effectively avoided.

[0054] In this embodiment, the two vertical plates 6 are both slidably installed on the bottom of the mounting block 2 along the direction of the mounting plate 211, and a bidirectional threaded rod 22 threadedly connected to the two vertical plates 6 is rotatably installed on the mounting block 2. A second motor 23 connected to the bidirectional threaded rod 22 is fixedly installed on the mounting block 2. When in use, the second motor 23 is controlled to work, so as to drive the bidirectional threaded rod 22 to rotate on the mounting block 2, thereby driving the two vertical plates 6 to move closer to or away from each other at the bottom of the mounting block 2, and adjusting the distance between the two vertical plates 6. Therefore, when clamping and positioning packaging boxes of different sizes, the distance between the two vertical plates 6 can be adjusted to achieve the adjustment of the distance between the two clamping blocks 613, so as to facilitate the clamping and positioning of packaging boxes of different sizes, so as to improve the clamping and positioning effect of packaging boxes of different sizes and improve applicability.
