[0027] In the related art, during the transportation of photovoltaic glass panels, the glass panels on the transport line are grabbed by a grabbing assembly and placed on a pallet in the unloading area. A mobile platform and a guide rail adapted to the mobile platform are provided at the bottom of the pallet. The guide rail can move the mobile platform from the unloading area to the forklift workstation through the bottom of the paper laying device. The worker drives the forklift to the forklift workstation to lift the pallet, and then moves it to the packaging area to package the glass panels. This method of transportation requires more manual participation and has a low degree of automation.

[0028] In the embodiment of the present application, the pallet and the glass plate 400 are transported by using the transport vehicle 100. The glass plate 400 is moved from the unloading area 100a to the packaging device 500 by the transport vehicle 100, and the degree of automation of this transport method is relatively high.

[0029] The first aspect of the present application provides a glass plate 400 transport system, see Figures 6 to 10 The glass plate 400 handling system includes a transport line 900, a packaging device 500 and a transport vehicle 100. The transport line 900 has a material unloading area 100a, and the transport line 900 is used to transport the glass plate 400. The packaging device 500 is used to grab the second pallet 300 and the glass plate 400 above the first pallet 200. The transport vehicle 100 can move between the material unloading area 100a and the packaging device 500, and the top surface of the transport vehicle 100 can be lifted up to carry the first pallet 200.

[0030] In one embodiment, the glass plate 400 handling system also includes a pallet carrying mechanism 600, which is used to place the second pallet 300. The pallet carrying mechanism 600 includes a frame 610, a carrying platform 620 and a plug-in assembly 630. The carrying platform 620 is movably mounted on the frame 610, and the plug-in assembly 630 is mounted on the carrying platform 620. The plug-in assembly 630 is used to lift or release the second pallet 300.

[0031] The first aspect of the present application provides a method for transporting. Figures 1 to 10 , the handling method is applied to the glass handling system. The handling methods include: Step S100: driving the transport vehicle to move below the first pallet in the unloading area; Step S200: Control the top surface of the transport vehicle to lift up, so that the transport vehicle lifts the first pallet and carries the first pallet; Step S300: driving the transport vehicle to move to the packaging device; Step S400: driving the packaging device to grab the second tray, so that the second tray and the corresponding glass plate are separated from the first tray; Step S500: placing another second tray on top of the first tray; Step S600: driving a transport vehicle carrying a first pallet and a corresponding second pallet to move to a material unloading area; Step S700: driving the top surface of the transport vehicle to move downward to release the first pallet and the corresponding second pallet.

[0032] A second tray 300 is placed above the first tray 200 , and the second tray 300 is used to carry the glass plates 400 . The unloading area 100 a is used to stack the processed glass plates 400 .

[0033] Exemplarily, the first pallet 200 includes a carrier 210 and a support 220, the support 220 is connected to the bottom surface of the carrier 210, the number of the support 220 is multiple, and the multiple support 220 are arranged at intervals from each other. The second pallet 300 is placed on the side of the carrier 210 away from the support 220. The transport vehicle 100 can move into the interval between the multiple support 220 and stay on the bottom surface of the carrier 210.

[0034] Exemplarily, when projected in the up-down direction, the projection area of ​​the carrier 210 and the projection area of ​​the second tray 300 are both rectangular, so as to better fit the shape of the glass plate 400 .

[0035] Exemplarily, when projected in the up-down direction, the projection area of ​​the transport vehicle 100 is located within the projection area of ​​the first pallet 200. Thus, the mutual interference between the transport vehicle 100 and the external environment can be reduced.

[0036] Exemplarily, the transport vehicle 100 is an AGV (Automated Guided Vehicle) transport vehicle 100. The transport vehicle 100 has a driving device and a bearing surface, and the bearing surface can move up and down under the driving action of the driving device. The bearing surface is located on the top surface of the transport vehicle 100.

[0037] In the scheme of the embodiment of the present application, the glass plate 400 is transferred by driving the transport vehicle 100 to move below the first tray 200 located in the unloading area 100a. The process of moving the glass plate 400 from the unloading area 100a to the packaging device 500 is all moved by the transport vehicle 100, and the automation degree of the glass plate 400 is high and a part of the labor cost can be saved. Furthermore, the transport vehicle 100 supports the first tray 200 from the bottom surface of the first tray 200 and drives the first tray 200 to move, which can reduce the occupied space of the transport equipment, thereby reducing the situation of mutual interference between the transport equipment and other equipment in the glass plate 400 handling system during transportation. Further, the lower part of the first tray 200 needs to be entered by the transport vehicle 100, and the bearing surface of the first tray 200 needs to be raised. The packaging device 500 grabs the second push plate and the glass plate 400 above the first tray 200, which can reduce the overall height of the packaged product, the difficulty of packaging is low, and the occupied height of the product can be saved.

[0038] Exemplarily, the packaging device 500 includes a gantry 510, a robot 520 and a transmission line 530. The robot 520 is installed on the gantry 510, and the second pallet 300 and the glass plate 400 above the second pallet 300 are moved to the transmission line 530 by driving the robot 520 to move and grab the second pallet 300, so as to perform packaging operations.

[0039] It is understandable that after the packaging device 500 grabs the second pallet 300, the top surface of the transport vehicle 100 still supports the first pallet 200. The first pallet 200 can be reused, thereby reducing costs.

[0040] Exemplarily, a gap is formed on the side of the second pallet 300 , and during the grabbing process of the packing device 500 , the packing device 500 can extend into the gap of the second pallet 300 , thereby lifting the second pallet 300 .

[0041] It should be noted that it is difficult for the packaging device 500 to directly grab the glass plate 400 for packaging, so it is necessary to place the second tray 300 above the first tray 200 to carry the glass plate 400, so as to facilitate the packaging device 500 to grab the second tray 300 to transfer the glass plate 400.

[0042] It is understandable that the unloading area 100a is located near the conveyor belt of the transportation line 900, so that the glass plates 400 on the transportation line 900 can be easily transferred from the transportation line 900 to the unloading area 100a.

[0043] In the solution of the embodiment of the present application, the first tray 200 and the corresponding second tray 300 are placed in the unloading area 100a by the transport vehicle 100, so as to receive the processed glass plates 400. When a certain number of glass plates 400 on the second tray 300 located in the unloading area 100a are accumulated, the transport vehicle 100 can move to the bottom of the second tray 300, thereby realizing the cycle of the transport method.

[0044] It is understandable that after the top surface of the transport vehicle 100 moves downward to release the first pallet 200 and the corresponding second pallet 300, the transport vehicle 100 can move out of the unloading area 100a and then transport the first pallet 200 of other unloading areas 100a. It can also stay in the unloading area 100a and wait for the glass plates 400 in the corresponding unloading area 100a to accumulate to a preset number before directly transporting.

[0045] In one embodiment, please refer to Figure 2 The step of placing another second tray 300 on the first tray 200 includes: Step S510: driving the transport vehicle to move below the pallet bearing mechanism; Step S520: Control the tray supporting mechanism to place another second tray on the first tray.

[0046] The pallet carrying mechanism 600 is a mechanism for placing a new second pallet 300 on the transport vehicle 100 .

[0047] It is understandable that the second pallet 300 on the pallet carrying mechanism 600 can be prepared in advance, and there can be multiple second pallets 300 on the pallet carrying mechanism 600. When the transport vehicle 100 moves to the bottom of the pallet carrying mechanism 600, the pallet carrying mechanism 600 will place one of the carried second pallets 300 above the first pallet 200 corresponding to the transport vehicle 100.

[0048] In the solution of the embodiment of the present application, when the transport vehicle 100 reaches the bottom of the carrying mechanism in the pallet, another second pallet 300 can be placed on the first pallet 200 through the pallet carrying mechanism 600. The process of placing the second pallet 300 can be completed by the mechanism, thereby further improving the degree of automation of the handling method and saving the cost of manual handling.

[0049] It is understandable that the embodiments of the present application are not limited to placing another second tray 300 on top of the first tray 200 by the tray carrying mechanism 600. For example, another second tray 300 can be placed on the first tray 200 by manual transportation.

[0050] In one embodiment, please refer to Fig.10 The tray bearing mechanism 600 includes a frame 610, a bearing platform 620, and a plug-in assembly 630. The bearing platform 620 can move in the up-down direction relative to the frame 610, and the plug-in assembly 630 is installed on the bearing platform 620. The plug-in assembly 630 is driven to move by the up-down movement of the bearing platform 620. The second tray 300 is supported above the plug-in assembly 630, so the second tray 300 can be moved by moving the bearing platform 620.

[0051] In one embodiment, please refer to Figure 3 The step of controlling the tray carrying mechanism 600 to place another second tray 300 above the first tray 200 includes: Step S521: the mobile carrying platform moves downward so that the second tray carried by the plug-in assembly is placed on the top surface of the first tray; Step S522: Control the plug-in assembly to release the second tray at the bottom.

[0052] In the solution of the embodiment of the present application, the second tray 300 is placed on the first tray 200 by moving the carrier 620 downward, and then releasing the second tray 300 at the bottom. The process of placing the second tray 300 is relatively simple and does not require manual intervention. Furthermore, the operating radius of the tray carrier mechanism 600 during the process of placing the second tray 300 is relatively small, which can reduce the interference between the tray carrier mechanism 600 and the external environment, and has higher safety.

[0053] It is understandable that the embodiments of the present application do not limit the method of placing the second tray 300 on the tray carrying mechanism 600. For example, the second tray 300 is placed on the carrying platform 620 of the tray carrying mechanism 600, and the second tray 300 is placed by grabbing the top second tray 300 by a robot arm and then placing it on the top of the first tray 200.

[0054] In one embodiment, please refer to Figure 4 The plug-in assembly 630 includes a driving member 631 and a plug-in member 632. The driving member 631 is installed on the carrier 620. The plug-in member 632 is driven and connected to the driving member 631. The steps of releasing the second tray 300 at the bottom include: Step S523: driving the driving member to disengage the connector from the second tray; Step S524: the mobile carrier moves upward so that the connector is located between the second tray at the bottom and the second tray adjacent to the second tray at the bottom; Step S525: driving the driving member to approach the second tray, so that the connector is carried on the second tray adjacent to the bottom second tray.

[0055] Exemplarily, the driving member 631 is a cylinder, a fixed end of the driving member 631 is mounted on the supporting platform 620 , and the connector 632 is connected to the movable end of the driving member 631 .

[0056] Exemplarily, the number of driving members 631 is at least two, and the multiple driving members 631 are arranged at intervals from each other. Each driving member 631 is correspondingly provided with a plug-in member 632. The multiple plug-in members 632 can make the plug-in assembly 630 more stable in the process of supporting the second tray 300.

[0057] It is understandable that, when the number of second trays 300 carried by the plug-in assembly 630 is only one, the second tray 300 can be released by controlling the driving member 631 to disengage the plug-in member 632 from the second tray 300 .

[0058] In the solution of the embodiment of the present application, the driving member 631 and the plug-in member 632 cooperate with each other to realize the placement of the second tray 300 during the up and down movement of the carrier 620, and the operation method is simple. Furthermore, this method of releasing the second tray 300 at the bottom can reduce the influence of the driving member 631 and the plug-in member 632 on the remaining second trays 300, thereby making the release process more stable.

[0059] For example, before the mobile carrying platform 620 moves downward to place the second pallet 300 carried by the plug assembly 630 on the top surface of the first pallet 200, the top surface of the transport vehicle 100 can be controlled to move downward until the top surface of the transport vehicle 100 is separated from the first pallet 200. The bottom of the first pallet 200 is supported on the ground to support the first pallet 200 and the second pallet 300 on the carrying platform 620. The bearing force on the transport vehicle 100 can be reduced to a certain extent, and the service life of the transport vehicle 100 is longer.

[0060] Exemplarily, the transport method further includes the step of loading the tray carrying mechanism 600: Controlling the carrying platform 620 to move upward, so that the supported second tray 300 moves upward; Control the forklift to place the second pallet 300 to be added to the pallet carrying mechanism 600 under the carrying platform 620; Control the carrying platform 620 to move downward so that the supported second tray 300 contacts the second tray 300 that needs to be replenished; Control the driving member 631 to drive the plug-in member 632 away from the second tray 300; Control the carrying platform 620 to move downward until the connector 632 is aligned with the lowermost second tray 300 that needs to be replenished; Control the driving member 631 to drive the plug-in member 632 to approach the second tray 300, so that the plug-in member 632 extends into the gap of the second tray 300; The carrying platform 620 is controlled to move upward, thereby completing the replenishment of the second tray 300 .

[0061] In one embodiment, please refer to Figure 1 Before driving the transport vehicle 100 to move below the first pallet 200 located in the unloading area 100a, the transport method further includes: Step S800: unloading: controlling the grabbing device to move the glass plate on the transport line to the second tray located in the unloading area; Step S900: laying paper: controlling the paper laying device to lay paper on the side of the glass plate in the unloading area away from the second tray; The unloading step and the paper laying step are repeatedly performed in sequence until the number of glass plates 400 on the second tray 300 reaches a preset number.

[0062] In the solution of the embodiment of the present application, the paper laying device 800 can lay paper between the glass plates 400 stacked on the second tray 300. The surface of the glass plates 400 is relatively smooth, and the direct contact between adjacent glass plates 400 may make it difficult to separate. Laying paper between adjacent glass plates 400 can facilitate the separation of adjacent glass plates 400, which is more convenient in the process of packing the glass plates 400.

[0063] In one embodiment, please refer to Figure 6 and Fig. 9 The paper laying device 800 includes a traction member, a cutting member, and a roll assembly 810. The roll assembly 810 is used to roll up paper. The axial direction of the roll assembly 810 is arranged along the transport direction of the transport line 900. The unloading area 100a is located between the roll assembly 810 and the transport line 900. It can be understood that paper is usually rolled up on the roll assembly 810 with the axial direction of the roll assembly 810 as the axis. The axial direction of the roll assembly 810 is arranged crosswise along the transport direction of the transport line 900, which can facilitate the traction member to pull the paper from the roll assembly 810 to the top of the glass plate 400.

[0064] In one embodiment, please refer to Figure 5 , the steps of laying paper include: Step S910: driving the traction member to pull the paper wound by the roller assembly to the upper surface of the glass plate; Step S920: controlling the cutting unit to cut the paper.

[0065] Exemplarily, the axial direction of the roller assembly 810 is arranged parallel to the transport direction of the transport line 900. The arrangement direction of the roller assembly 810 and the unloading area 100a is arranged orthogonally to the transport direction of the transport line 900.

[0066] For example, the traction member can pull the paper to the top of the glass plate 400 along the arrangement direction of the roller assembly 810 and the unloading area 100a. The cutting member can cut the paper along the axial direction of the roller assembly 810.

[0067] In the solution of the embodiment of the present application, the traction member and the cutting member cooperate with each other to realize automatic paper laying on the glass plate 400, and the paper laying efficiency is relatively high.

[0068] It is understandable that the embodiments of the present application do not limit the structural form of the paper laying device 800.

[0069] In one embodiment, please refer to Figure 6 and Fig. 9 There are multiple unloading areas 100a, which are arranged at intervals along the transport direction of the transport line 900, and each unloading area 100a is correspondingly provided with a paper laying device 800.

[0070] Exemplarily, there are multiple transport vehicles 100 , and the number of transport vehicles 100 is equal to or less than the number of unloading areas 100 a .

[0071] Exemplarily, when the number of transport vehicles 100 is equal to the number of unloading areas 100a, each unloading area 100a corresponds to a transport vehicle 100, and when the transport vehicle 100 carries the first pallet 200 and the second pallet 300 in the corresponding unloading area 100a, the transport vehicle 100 stays at the bottom of the first pallet 200. When the number of glass plates 400 on the second pallet 300 reaches a preset number, the transport vehicle 100 lifts the first pallet 200 and transports it to the packaging device 500.

[0072] For example, when the number of transport vehicles 100 is less than the number of unloading areas 100a, when the transport vehicle 100 carries the first pallet 200 and the second pallet 300 in the corresponding unloading area 100a, the transport vehicle 100 exits the unloading area 100a, and moves to the bottom of the first pallet 200 corresponding to the other unloading area 100a that has completed unloading or is about to complete unloading.

[0073] In the solution of the embodiment of the present application, there are multiple unloading areas 100a, and the multiple unloading areas 100a are arranged at intervals. The multiple unloading areas 100a can unload multiple glass plates 400 at the same time, and the handling efficiency of the glass plates 400 is relatively high.

[0074] It is understandable that the embodiments of the present application do not limit the number of unloading areas 100a.

[0075] In one embodiment, the first tray 200 is made of metal.

[0076] For example, the second pallet 300 is made of wood. The lower density of the material of the second pallet 300 can reduce the load on the first pallet 200 and the transport vehicle 100 .

[0077] In the solution of the embodiment of the present application, the material of the first tray 200 is metal, the first tray 200 can be reused, and the material strength of the first tray 200 is relatively high, which can reduce the deformation of the first tray 200, thereby increasing the service life of the first tray 200.

[0078] It is understandable that the embodiment of the present application does not limit the material of the first tray 200 .
