Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of photovoltaic module packaging, and in particular to a photovoltaic module packaging line and a photovoltaic module packaging process. BACKGROUND

[0002] Solar power generation has developed rapidly, and therefore the demand for solar modules, i.e. photovoltaic modules, has also rapidly increased. After production, photovoltaic modules need to be packaged for subsequent transportation. Since photovoltaic modules are flat, they are often stacked into a pile when being packaged, and then packaged. Packaging involves complex processes and multiple stations, and since there are many stations, a flow line is often designed.

[0003] Existing packaging lines are manually or semi-automatically packaged. An inner packaging tape needs to be manually packaged, and after the inner packaging tape is packaged, a carton needs to be manually sleeved, a carton cover needs to be manually covered, and a corner protector needs to be manually installed after the carton is sleeved. An outer packaging tape needs to be manually packaged, and then film needs to be manually wrapped, and top film needs to be manually covered. This wastes manpower and is low in packaging efficiency.

[0109] The photovoltaic module is stacked on the iron pallet by the grading machine, and then the photovoltaic module and the iron pallet are placed on the photovoltaic module feeding line 35, and a banding machine is arranged on the photovoltaic module feeding line 35, the banding machine is used to band the stacked photovoltaic modules, and then the photovoltaic module feeding line 35 transports the photovoltaic module and the iron pallet to the discharging end, and then the pallet replacing assembly 36 discharges the iron pallet and the photovoltaic module, and the pallet replacing assembly 36 turns over the photovoltaic module on the iron pallet to the wooden pallet, so that the horizontally stacked photovoltaic modules are turned over to be vertically placed, and then the vertically placed photovoltaic modules are transported to the photovoltaic module packing line 37 by the iron pallet replacing assembly 36, and subsequent steps such as banding, boxing and film covering are performed.

[0110] In this way, the stacked photovoltaic modules are turned over to be vertically placed, and the photovoltaic modules will not be scratched, the safety of the photovoltaic module packing is improved, and the production loss is greatly reduced.

[0111] The photovoltaic module 34 is stacked on the iron pallet by the grading machine to form a state as shown in Figure 30 The face where one short edge of the photovoltaic module 34 is located is named as the second side face 342, and the face where one long edge of the photovoltaic module is located is named as the first side face 341.

[0112] At present, the grading machine is divided into two types according to different functions, the first type of grading machine grasps the top face 343 of the photovoltaic module 34 to sequentially stack the photovoltaic module 34 on the pallet to form a state as shown in Figure 30

[0113] The second type of grading machine grasps the top face 343 of the photovoltaic module 34 and then rotates the photovoltaic module 34 to make the first side face 341 of the photovoltaic module 34 face downward, so that the photovoltaic module 34 is in a vertical state.

[0114] It should be noted that the photovoltaic module 34 will inevitably collide or shake during transportation, so the photovoltaic module 34 will not be packed in a stacked manner, because when the photovoltaic module 34 is stacked, once collision or shaking occurs, the glass of the photovoltaic module 34 is easily broken. When the second type of grading machine is used to pack the photovoltaic module, the photovoltaic module is also easily damaged.

[0115] In this embodiment, the first type of grading machine is used to grasp the top face 343 of the photovoltaic module 34 to sequentially stack the photovoltaic module 34 on the iron pallet to form a state as shown in Figure 30 ​As shown in the diagram, the iron pallet and photovoltaic module 34 are then conveyed together to the photovoltaic module loading line 35. The photovoltaic module loading line 35 is equipped with a strapping machine, which straps the stacked photovoltaic modules together to bind them and prevent them from tipping over during subsequent flipping. After that, the photovoltaic module loading line 35 conveys the photovoltaic modules and iron pallet to the unloading end. Then, the pallet changing component 36 unloads the iron pallet and photovoltaic modules and flips the photovoltaic modules on the iron pallet onto the wooden pallet, so that the horizontally stacked photovoltaic modules are flipped to be placed vertically, that is, the first side 341 of the photovoltaic module 34 is placed on the wooden pallet, or the second side 342 of the photovoltaic module 34 is placed on the wooden pallet.

[0116] Preferred, such as Figure 4 As shown, the pallet replacement assembly 36 includes a first pallet flipping mechanism 10 and a second pallet flipping mechanism 11. The photovoltaic module has a long side and a short side. The first pallet flipping mechanism 10 is used to flip the long side of the photovoltaic module to place it onto the wooden pallet, and the second pallet flipping mechanism 11 is used to flip the short side of the photovoltaic module to place it onto the wooden pallet. That is, after the first pallet flipping mechanism 10 flips the photovoltaic module, the first side 341 of the photovoltaic module serves as the bearing surface. After the second pallet flipping mechanism 11 flips the photovoltaic module, the second side 342 of the photovoltaic module serves as the bearing surface.

[0117] Because of the different packaging methods for photovoltaic modules, the required shape of the wooden pallets also varies, such as... Figure 31 As shown, there are two specifications of wooden pallets, namely the first wooden pallet 32 ​​and the second wooden pallet 33. The first wooden pallet 32 ​​and the second wooden pallet 33 have the same width, but their lengths are different. The first wooden pallet 32 ​​is longer than the second wooden pallet 33.

[0118] In this embodiment, a first wooden pallet 32 ​​is placed on a first pallet flipping mechanism 10, which flips the photovoltaic module onto the first wooden pallet 32, so that the first side 341 of the photovoltaic module is placed on the first wooden pallet 32. A second wooden pallet 33 is placed on a second pallet flipping mechanism 11, which flips the photovoltaic module 34 onto the second wooden pallet 33, so that the second side 342 of the photovoltaic module is placed on the second wooden pallet 33.

[0119] By adopting the two flipping methods mentioned above, the pressure between the photovoltaic modules 34 is reduced, which can effectively avoid the problem of glass breakage of the photovoltaic modules 34 due to collision.

[0120] In this embodiment, the photovoltaic modules 34 are stacked sequentially onto an iron tray using a first sorting machine to form... Figure 30After the iron tray and the photovoltaic module are shown in the state, the iron tray and the photovoltaic module are sent to the photovoltaic module feeding line 35, a banding machine on the photovoltaic module feeding line 35 preliminarily bands the stacked photovoltaic modules, the iron tray and the photovoltaic module move to the discharging end along the photovoltaic module feeding line 35, then the first wooden tray 32 is placed on the first tray turnover mechanism 10, and then the first tray turnover mechanism 10 is used to overturn the long side of the photovoltaic module 34 to overturn the long side of the photovoltaic module 34 to the first wooden tray 32, that is, to make the first side 341 of the photovoltaic module 34 overturn to the first wooden tray 32.

[0157] The photovoltaic module and the iron tray are fed from the feeding end of the first conveying line 2, the first conveying line 2 conveys the photovoltaic module and the iron tray to the first roller conveyor 5, the first roller conveyor 5 conveys the photovoltaic module and the iron tray to the sixth chain roller conveying mechanism 604, and then the photovoltaic module and the iron tray move to the fifth chain roller conveying mechanism 603 along the second conveying line 6, if the tray turnover assembly at the fifth chain roller conveying mechanism 603 is in an idle state, the photovoltaic module and the iron tray are discharged therefrom, if the tray turnover assembly at the fifth chain roller conveying mechanism 603 is in a working state, the second conveying line 6 continues to convey the photovoltaic module and the iron tray to the fourth chain roller conveying mechanism 602, and then the photovoltaic module and the iron tray are discharged at the fourth chain roller conveying mechanism 602, and the tray turnover assembly at the fourth chain roller conveying mechanism 602 performs the turnover work of the photovoltaic module.

[0158] In this way, the packaging efficiency of the photovoltaic module can be improved, two sets of tray turnover assemblies can be arranged to work simultaneously, and the waiting time of the iron tray and the photovoltaic module on the second conveying line 6 can be reduced.

[0159] Preferably, as shown in the drawings, Figure 5 As shown, the first conveying line 2 includes a plurality of first conveying frames 201 arranged in sequence, the leftmost first conveying frame 201 is provided with a first chain roller conveying mechanism 203, the rightmost first conveying line 2 is provided with a second chain roller conveying mechanism 204, and each first conveying line 2 is provided with a first chain conveying mechanism 202.

[0161] Preferably, as shown in the drawings, Figure 2As shown, the photovoltaic module feeding line 35 further comprises a code scanning assembly 24 and a photovoltaic module recycling line 4, wherein the code scanning assembly 24 is installed on a first conveying frame 201 on the right side of the first chain roller conveying mechanism 203. The photovoltaic module recycling line 4 comprises a carrying frame 401, a third chain roller conveying mechanism 403, a second roller conveyor 402 and a first discharging elevator 3.

[0163] When the photovoltaic module moves to the code scanning assembly 24, the code scanning assembly 24 scans the bar code on the photovoltaic module to obtain the information of the bar code. If the bar code is repeated or damaged, the code scanning assembly 24 uploads the error information to the general control system. When the photovoltaic module moves to the feeding end of the second conveying line 6, the photovoltaic module moves to the right on the third chain roller conveying mechanism 403 from the feeding end of the second conveying line 6, and then the third chain roller conveying mechanism 403 conveys the photovoltaic module to the second roller conveyor 402, and finally the first discharging elevator 3 removes the problematic photovoltaic module from the discharging end of the second roller conveyor 402. The recycling of the problematic photovoltaic module can be realized, so that the staff can immediately check the bar code, and the production efficiency is improved.

[0165] In this way, the height of the code scanning mechanism 242 is adjusted by driving the cross beam 241 to lift through the lifting mechanism, so that the code scanning mechanism 242 is the same height as the bar code on the side of the photovoltaic module, and then the code scanning mechanism 242 moves left and right through the horizontal moving mechanism, so that the code scanning mechanism 242 is directly opposite the bar code.

[0166] It should be noted that the position of the bar code on the photovoltaic module is fixed, so the horizontal moving mechanism and the lifting mechanism only need to be set to the stroke, and the bar code can be quickly positioned.

[0167] Optionally, the lifting mechanism can use a belt drive lifting mechanism or a screw lifting mechanism. The horizontal moving mechanism can use a linear module.

[0168] Optionally, the code scanning mechanism 242 comprises a camera, which acquires the information of the barcode through the camera. Alternatively, a code scanning gun or a code scanner can be used as long as it can read the information of the barcode.

[0169] Preferably, in combination Figure 6 and Figure 7 , the second conveying line 6 comprises a plurality of second conveying racks 601 arranged in sequence, and each of the second conveying racks 601 has two layers, and the rightmost second conveying rack 601 is provided with a sixth chain and roller conveying mechanism 604, which is connected to the first roller conveying machine 5 and the third chain and roller conveying mechanism 403.

[0172] When the photovoltaic module moves to the sixth chain and roller conveying mechanism 604 along with the movement of the roller conveying structure of the sixth chain and roller conveying mechanism 604, if the barcode on the photovoltaic module has a problem, the chain conveying structure of the sixth chain and roller conveying mechanism 604 is started to drive the photovoltaic module to move towards the direction of the carrier 401, so as to move the photovoltaic module to the third chain and roller conveying mechanism 403, and the chain conveying structure of the third chain and roller conveying mechanism 403 is started to make the photovoltaic module enter the third chain and roller conveying mechanism 403, and finally the roller conveying structure of the third chain and roller conveying mechanism 403 is started to convey the photovoltaic module to the second roller conveying machine 402.

The upper layers of the two second conveying frames 601 between the fifth chain roller conveying mechanism 603 and the sixth chain roller conveying mechanism 604 are each provided with the second chain conveying mechanism 605.

[0175] Further, the upper layers of the four second conveying frames 601 between the fifth chain roller conveying mechanism 603 and the fourth chain roller conveying mechanism 602 are each provided with the second chain conveying mechanism 605, and the lower layers of the four second conveying frames 601 are each provided with the third chain conveying mechanism 608.

[0176] Thus, a tray overturning assembly is arranged at the back of the fifth chain roller conveying mechanism 603 and the back of the fourth chain roller conveying mechanism 602, respectively.

[0177] That is, the fifth chain roller conveying mechanism 603 and the fourth chain roller conveying mechanism 602 are both unloading ends.

[0178] Preferably, as shown in Figure 7 、 Figure 8 and Figure 9 , the photovoltaic module feeding conveying system further comprises a third conveying line 8, the third conveying line 8 comprises a plurality of third conveying frames 801 arranged in sequence, the third conveying line 8 is located between the first conveying line 2 and the second conveying line 6, and the second conveying line 6 and the third conveying line 8 are parallel.

[0179] Each third conveying frame 801 has an upper layer and a lower layer. As viewed from the perspective of Figure 2 , the upper layer of the third conveying frame 801 at the rightmost end is provided with the ninth chain roller conveying mechanism 803, and the lower layer of the third conveying frame 801 at the rightmost end is provided with the tenth chain roller conveying mechanism 804. The ninth chain roller conveying mechanism 803 is connected to the fifth chain roller conveying mechanism 603, and the photovoltaic module on the fifth chain roller conveying mechanism 603 can be moved to the ninth chain roller conveying mechanism 803.

[0181] In this way, the photovoltaic module and the iron tray move from the sixth chain roller conveying mechanism 604 to the fifth chain roller conveying mechanism 603. If the photovoltaic module turnover mechanism at the fifth chain roller conveying mechanism 603 is in an idle state at this time, the photovoltaic module moves to the fifth chain roller conveying mechanism 603 and stops, and then the second unloading elevator 9 at the fifth chain roller conveying mechanism 603 takes the photovoltaic module on the fifth chain roller conveying mechanism 603. If the photovoltaic module turnover mechanism at the fifth chain roller conveying mechanism 603 is in a working state at this time, the photovoltaic module on the fifth chain roller conveying mechanism 603 continues to move towards the fourth chain roller conveying mechanism 602.

[0182] If both of the photovoltaic module turnover mechanisms are in a working state, when the photovoltaic module moves to the fifth chain roller conveying mechanism 603, the roller conveying structure in the fifth chain roller conveying mechanism 603 is opened to drive the photovoltaic module to move towards the ninth chain roller conveying mechanism 803, so that the photovoltaic module is temporarily stored on the ninth chain roller conveying mechanism 803. When the photovoltaic module turnover mechanism at the fifth chain roller conveying mechanism 603 is in an idle state, the ninth chain roller conveying mechanism 803 moves the photovoltaic module to the fifth chain roller conveying mechanism 603, and then the second unloading elevator 9 at the fifth chain roller conveying mechanism 603 unloads.

[0183] In this way, the temporary storage function is increased to temporarily store the photovoltaic module, the design is reasonable, and the work efficiency is improved.

[0184] It should be noted that there are two kinds of recycling paths for the iron tray at the eighth chain roller conveying mechanism 607. The first kind is that the roller conveying structure on the eighth chain roller conveying mechanism 607 is opened to convey the iron tray to the tenth chain roller conveying mechanism 804, and then the roller conveying structure on the tenth chain roller conveying mechanism 804 is opened to convey the photovoltaic module to the fifth chain conveying mechanism 805, and the photovoltaic module moves to the fourth conveying line 7 along the fifth chain conveying mechanism 805.

[0185] The second kind is that the chain conveying structure on the eighth chain roller conveying mechanism 607 is opened to convey the photovoltaic module to the third chain conveying mechanism 608, and the photovoltaic module moves to the seventh chain roller conveying mechanism 606 along the third chain conveying mechanism 608, and then the roller conveying structure on the seventh chain roller conveying mechanism 606 is opened to send the photovoltaic module into the fourth conveying line 7.

[0186] Two recycling paths are designed, which can recycle more iron pallets at the same time and improve the recycling efficiency of iron pallets.

[0187] It should be noted that the recycling mode of the iron pallet located at the seventh chain roller conveying mechanism 606 is that after the photovoltaic module enters the seventh chain roller conveying mechanism 606, the roller conveying structure in the seventh chain roller conveying mechanism 606 is opened to convey the iron pallet to the fourth conveying line 7, and then the fourth conveying line 7 is removed.

[0188] Preferably, as shown in Figure 7 and Figure 10 The fourth conveying line 7 includes an eleventh chain roller conveying mechanism 701 and a third roller conveying machine 702 and a third unloading elevator 703 connected in sequence, the eleventh chain roller conveying mechanism 701 is connected with the seventh chain roller conveying mechanism 606, specifically, the feeding end of the chain conveying structure in the eleventh chain roller conveying mechanism 701 is adjacent to the discharging end of the roller conveying structure in the seventh chain roller conveying mechanism 606. The conveying direction of the chain conveying structure in the eleventh chain roller conveying mechanism 701 is consistent with the conveying direction of the fifth chain conveying mechanism 805, the chain conveying structure in the eleventh chain roller conveying mechanism 701 is aligned with the fifth chain conveying mechanism 805, and the third unloading elevator 703 is arranged at the discharging end of the third roller conveying machine 702.

[0189] In this way, the iron pallet in the fifth chain conveying mechanism 805 can be conveyed to the chain conveying structure in the eleventh chain roller conveying mechanism 701, and after the iron pallet is stabilized, the roller conveying structure in the eleventh chain roller conveying mechanism 701 is opened to convey the iron pallet to the third roller conveying machine 702.

[0190] Further, the iron pallet entering the seventh chain roller conveying mechanism 606 can be conveyed to the eleventh chain roller conveying mechanism 701, and then the roller conveying structure on the eleventh chain roller conveying mechanism 701 is opened to convey the iron pallet to the third roller conveying machine 702, and finally the iron pallet is taken off from the third unloading elevator 703.

[0191] It should be noted that the first chain roller conveying mechanism 203, the second chain roller conveying mechanism 204, the third chain roller conveying mechanism 403, the fourth chain roller conveying mechanism 602, the fifth chain roller conveying mechanism 603, the sixth chain roller conveying mechanism 604, the seventh chain roller conveying mechanism 606, the eighth chain roller conveying mechanism 607, the ninth chain roller conveying mechanism 803, the tenth chain roller conveying mechanism 804 and the eleventh chain roller conveying mechanism 701 are completely same.

[0192] Preferably, the chain and roller conveying mechanism comprises a chain conveying structure and a roller conveying structure, wherein the chain conveying structure comprises three chain conveying modules, namely chain conveying module one 25, chain conveying module two 26 and chain conveying module three 27 in sequence, and the roller conveying structure comprises two roller conveying modules, namely roller conveying module one 28 and roller conveying module two 29 in sequence.

[0193] The three chain conveying modules are arranged in parallel, the roller conveying module one 28 is located between the chain conveying module one 25 and the chain conveying module two 26, the roller conveying module two 29 is arranged between the chain conveying module two 26 and the chain conveying module three 27, the conveying direction of the chain conveying modules is perpendicular to the conveying direction of the roller conveying modules, and the upper surfaces of the chain conveying modules are flush with the upper surfaces of the roller conveying modules.

[0194] In this way, when the photovoltaic module or the iron tray is moved from the three chain conveying modules to the middle position of the chain and roller conveying mechanism, the three chain conveying modules stop working, and then the two roller conveying modules operate to move the photovoltaic module or the iron tray out of the chain and roller conveying mechanism.

[0195] Further, the chain and roller conveying mechanism further comprises a roller driving mechanism 30 and a chain driving mechanism 31, the roller driving mechanism 30 is used to drive the two roller conveying modules to operate synchronously, and the chain driving mechanism 31 is used to drive the three chain conveying modules to operate synchronously.

[0196] As shown in Figure 10 , the roller driving mechanism 30 comprises a fifth motor 3001, a driving sprocket 3002, a sprocket shaft, a driven sprocket 3003 and a driving chain 3004. The fifth motor 3001 is installed at the bottom of the roller conveying module two 29, the driving sprocket 3002 is installed on the output end of the fifth motor 3001, a bottom plate is installed at the bottom of the roller conveying module one 28, the sprocket shaft is rotatably installed on the bottom plate through two bearing seats, and the driven sprocket 3003 is fixedly installed on the sprocket shaft.

[0197] It should be noted that a first sprocket is also installed on the sprocket shaft, the first sprocket is located at the back of the driven sprocket 3003, the first sprocket and the driven sprocket 3003 are coaxially arranged, and the driven sprocket 3003 and the driving sprocket 3002 are connected through the driving chain 3004. The roller conveying module one 28 and the roller conveying module two 29 each comprise a plurality of rollers, a second sprocket is installed at the same end of each roller, the plurality of second sprockets are connected through a first chain, and a second chain is connected between the first sprocket and one second sprocket.

[0198] Thus, the fifth motor 3001 drives the driving sprocket 3002 to rotate, the driving sprocket 3002 drives the driven sprocket 3003 to rotate through the driving chain 3004, so as to drive the sprocket shaft to rotate, the sprocket shaft drives the first sprocket to rotate synchronously, the first sprocket drives the second sprocket to rotate, so as to drive the second sprocket on the roller to rotate, and the plurality of second sprockets are connected through the first chain, so as to drive the plurality of rollers to rotate synchronously.

[0199] Preferably, as shown in the figure, the chain drive mechanism 31 comprises a sixth motor 311, a rotating shaft 312, a first fixed sprocket, a second fixed sprocket 313 and three third fixed sprockets. Figure 11

[0200] The output end of the sixth motor 311 is provided with a first fixed sprocket, and the rotating shaft 312 is provided with a second fixed sprocket 313 and three third fixed sprockets. The three fixed sprockets are connected with the three chain conveying structures through chains, and the first fixed sprocket and the second fixed sprocket 313 are connected through a fixed chain. Thus, the sixth motor 311 drives the first fixed sprocket to rotate, so as to drive the rotating shaft 312 and the three third fixed sprockets to rotate synchronously, and finally drive the three chain conveying structures to work synchronously.

[0201] In summary, when the photovoltaic modules are packed, the photovoltaic modules are stacked on the iron tray by the grading machine, the bar code is pasted on the photovoltaic modules, the iron tray and the photovoltaic modules are placed on the feeding elevator 1 by the forklift, the iron tray and the photovoltaic modules are fed to the first chain roller conveying mechanism 203 by the feeding elevator 1, the iron tray and the photovoltaic modules are conveyed to the first conveying line 2 by the first chain roller conveying mechanism 203, the photovoltaic modules and the iron tray pass below the code scanning assembly 24, the code scanning assembly 24 scans the bar code on the photovoltaic modules and obtains the information of the bar code, and uploads the information of the bar code to the general control system. The general control system determines which packing method is needed for the current photovoltaic modules. If the bar code is repeated or damaged, the code scanning assembly 24 uploads the error information to the general control system.

[0202] Then, the preliminary banding machine at the first conveying line 2 is used to preliminarily band the stacked photovoltaic modules, so as to bundle the photovoltaic modules together.

[0203] ​After the initial banding, the photovoltaic module and the iron tray are moved from the second chain roller conveying mechanism 204 to the first roller conveyor 5, and then moved to the sixth chain roller conveying mechanism 604 via the first roller conveyor 5. If the barcode is problematic, the sixth chain roller conveying mechanism 604 at this time conveys the photovoltaic module and the iron tray to the third chain roller conveying mechanism 403, and then discharged from the first discharge elevator 3 via the second roller conveyor 402. If the barcode is correct, the sixth chain roller conveying mechanism 604 conveys the photovoltaic module and the iron tray to the second chain conveying mechanism 605 and continues to move to the fifth chain roller conveying mechanism 603.

[0204] If the tray turnover assembly at the fifth chain roller conveying mechanism 603 at this time is in an idle state, the second discharge elevator 9 at this time discharges. If the tray turnover assembly at the fifth chain roller conveying mechanism 603 at this time is in a working state, the photovoltaic module and the iron tray continue to move to the fourth chain roller conveying mechanism 602.

[0205] Next, the jacking mechanism in the second discharge elevator 9 drives the first roller conveying mechanism 903 to rise so that the first roller conveying mechanism 903 is flush with the second conveying line 6, and then the photovoltaic module and the iron tray are conveyed to the first roller conveying mechanism 903, and the first roller conveying mechanism 903 is opened to completely move the photovoltaic module and the iron tray onto the first roller conveying mechanism 903.

[0206] According to the information of the barcode obtained by the general control system, if the obtained information is to turn over the long side of the photovoltaic module, the first tray turnover mechanism 10 starts to work, the first tray turnover mechanism 10 turns over the photovoltaic module on the second discharge elevator 9 to the first wooden tray 32, and then the ground rail mechanism in the first tray turnover mechanism 10 drives the photovoltaic module and the first wooden tray 32 to move to the fourth roller conveyor 13, so that the third roller conveying mechanism 21 in the first tray turnover mechanism 10 is aligned with the fourth roller conveyor 13, and the third roller conveying mechanism 21 in the second tray turnover mechanism 11 at this time is in a horizontal state, and the feeding end of the third roller conveying mechanism 21 in the second tray turnover mechanism 11 is aligned with the fourth roller conveyor 13, and the discharging end of the third roller conveying mechanism 21 in the second tray turnover mechanism 11 is aligned with the feeding end of the packaging production line, and the photovoltaic module and the first wooden tray 32 can be moved from the third roller conveying mechanism 21 in the first tray turnover mechanism 10 to the fourth roller conveyor 13, and then moved to the third roller conveying mechanism 21 in the second tray turnover mechanism 11 via the fourth roller conveyor 13, and then enter the packaging production line via the third roller conveying mechanism 21 in the second tray turnover mechanism 11.

[0207] If the obtained information is to flip the short side of the photovoltaic module, after the second blanking elevator 9 takes down the iron tray and the photovoltaic module, the iron tray and the photovoltaic module continue to move towards the rotating conveyor 12, so that the iron tray and the photovoltaic module move onto the rotating conveyor 12, the rotating conveyor 12 drives the iron tray and the photovoltaic module to rotate, so that the short side of the photovoltaic module is flipped towards the second tray flipping mechanism 11, the second tray flipping mechanism 11 flips the photovoltaic module onto the second wooden tray 33, and then the ground rail mechanism in the second tray flipping mechanism 11 drives the photovoltaic module to move to the original position, at this time the discharge end of the third roller conveyor mechanism 21 in the second tray flipping mechanism 11 is aligned with the feeding end of the photovoltaic module packaging production line, then the third roller conveyor mechanism 21 in the second tray flipping mechanism 11 is started, so that the photovoltaic module and the second wooden tray 33 move to the feeding end of the photovoltaic module packaging production line.

[0208] The embodiment provides a photovoltaic module packaging line 37, which comprises a Y-direction roller conveying line 38, a first banding mechanism 56, a packaging mechanism, a second banding mechanism, a third banding mechanism, a wooden batten mounting mechanism, a corner mounting mechanism and a film covering mechanism; the first banding mechanism 56, the packaging mechanism, the second banding mechanism, the third banding mechanism and the film covering mechanism are sequentially arranged along the conveying direction of the Y-direction roller conveying line 38; the Y-direction roller conveying line 38 is used for conveying a wooden tray 64 on which a photovoltaic module 34 is placed; the first banding mechanism 56 is used for banding the photovoltaic module 34 and the wooden tray 64 with a first band; the packaging mechanism is used for packaging the photovoltaic module 34 with a carton; the second banding mechanism is used for banding the carton and the wooden tray 64 with a second band; the third banding mechanism is used for banding the carton with a third band; and the film covering mechanism is used for covering the carton with a film; the wooden batten mounting mechanism and the corner mounting mechanism are both arranged at the third banding mechanism; and the photovoltaic module 34 has a first placement mode and a second placement mode; when the photovoltaic module 34 is in the first placement mode, the wooden batten mounting mechanism is used for mounting a wooden batten 44 before the third banding mechanism bands the carton with the third band; and when the photovoltaic module 34 is in the second placement mode, the corner mounting mechanism is used for mounting a corner 48 before the third banding mechanism bands the carton with the third band.

[0209] In the packaging process of the photovoltaic module 34, the wooden pallet 64 on which the photovoltaic module 34 is placed is sequentially sent to the first banding mechanism 56, the packaging mechanism, the second banding mechanism, the third banding mechanism and the film covering mechanism through the Y-direction roller conveying line 38, wherein when the photovoltaic module 34 conveyed by the Y-direction roller conveying line 38 is in the first placement mode, the wooden guard rail mounting mechanism first adds the wooden guard rail 44 to the side of the carton, and the third banding mechanism then bands the third guard rail for the carton and the wooden guard rail 44; when the photovoltaic module 34 conveyed by the Y-direction roller conveying line 38 is in the second placement mode, the corner mounting mechanism first adds the corner 48 to the side corner of the carton, and the third banding mechanism then bands the third guard rail for the carton and the corner 48, so as to realize the packaging of the photovoltaic module 34 in two different placement modes, improve the adaptability of the photovoltaic module packaging line 37, save space and cost compared with the form of packaging the photovoltaic module 34 in two different placement modes through two packaging lines, and the photovoltaic module packaging line 37 provided by the application runs stably, can automatically package large-size photovoltaic module 34 products, saves labor, and has high packaging efficiency.

[0212] In the embodiment, the wood guard 44 is frame-shaped and has a support diagonal beam between one of the opposite corners, and the left and right sides have flanges, so that the left and right sides are buckled at the corners of the carton together with the flanges. The wood guards 44 are stacked on the tray and placed in the wood guard buffer device 42. One pair of mechanical hands 41 corresponds to one pair of wood guard buffer devices 42. The mechanical hand 41 grabs the wood guard 44 in the corresponding wood guard buffer device 42 and first places it on the wood guard correcting device 40 for correction. Then the corrected wood guard 44 is grabbed, and one pair of mechanical hands 41 installs the wood guard 44 on the two sides opposite to the conveying direction of the carton along the Y-direction roller conveying line 38, respectively. At the same time, two pairs of supporting devices 43 support the two wood guards 44, respectively, and the mechanical hand 41 is removed. The supporting device 43 supports the lower side of the wood guard 44 to avoid affecting the transverse banding.

[0213] In an optional technical solution of the embodiment, the wood guard correcting device 40 includes a driving assembly, four bearing assemblies, a first correcting seat 4009 and a second correcting seat 40010. The first correcting seat 4009 and the second correcting seat 40010 are oppositely arranged, and the first correcting seat 4009 is provided with a first through slot, and the second correcting seat 40010 is provided with a second through slot. The first through slot is parallel to the second through slot. The left and right sides of the first correcting seat 4009 are provided with bearing assemblies, and the left and right sides of the second correcting seat 40010 are provided with bearing assemblies. The connecting lines of the four bearing assemblies form a rectangle and are used to bear the four corners of the wood guard 44. The driving assembly is used to drive the first correcting seat 4009 and the second correcting seat 40010 to rotate synchronously. The first correcting seat 4009 and the second correcting seat 40010 can approach or move away from each other. The wood guard 44 has opposite first and second edges.

Since the first and second edges are not in the same plane, the second edge does not enter the second through slot at this time, that is, the second through slot is crossed with the second edge. At this time, the first and second correcting seats 4009 and 40010 are driven to rotate synchronously by the driving assembly. Since the first and second edges are far away from each other, the rotating force of the first correcting seat 4009 on the first edge does not make the second edge rotate. At the same time, the second correcting seat 40010 rotates to make the second through slot rotate from the position crossed with the second edge to the position parallelly opposite to the second edge. At this time, the second edge enters the second through slot under the action of the force that the first and second correcting seats 4009 and 40010 are close to each other. Since the first and second through slots are parallel, the first edge in the first through slot is parallel to the second edge in the second through slot, thereby realizing the correction of the wood batten 44, making the wood batten 44 as a whole in the same plane, and saving manpower with simple structure and good correction effect.

[0215] In an optional technical solution of the embodiment, a pair of clamping jaws 4002 are further included, which are respectively arranged on the left and right sides of the first correcting seat 4009. The clamping jaws 4002 are used to clamp the first edge, and make the first edge enter the first through slot by clamping the first edge.

[0216] In this embodiment, the clamping space of the clamping jaw 4002 is larger than the width of the first through slot. When the first and second alignment seats 4009 and 40010 are close to each other and abut against the first and second edges respectively, the first edge can enter the clamping space of the clamping jaw 4002 because the clamping space of the clamping jaw 4002 is larger than the width of the first through slot. The clamping jaw 4002 clamps the first edge. Because the pair of clamping jaws 4002 are arranged on the left and right sides of the first alignment seat 4009 respectively, the pair of clamping jaws 4002 clamp the first edge at the same time to make the first edge flat. When the first and second alignment seats 4009 and 40010 are close to each other and abut against the first and second edges respectively, even if the first edge is in a cross shape and does not enter the first through slot, after the pair of clamping jaws 4002 clamp the first edge to make it flat, the first edge is parallel to and opposite to the first through slot. At this time, under the action of the force that the first and second alignment seats 4009 and 40010 are close to each other, the first edge enters the first through slot. Before the driving assembly drives the first and second alignment seats 4009 and 40010 to rotate synchronously, the clamping jaw 4002 releases the first edge to avoid that the clamping jaw 4002 drives the first edge to rotate. It should be noted that the width of the first through slot is slightly larger than the thickness of the first edge, which facilitates the entry of the first edge. The width of the second through slot is slightly larger than the thickness of the second edge, which facilitates the entry of the second edge. When the clamping jaw 4002 clamps the first edge, the clamping space of the clamping jaw 4002 is slightly larger than the thickness of the first edge, so that the first edge can enter the first through slot under the action of the force that the first and second alignment seats 4009 and 40010 are close to each other.

When the wood batten 44 needs to be aligned, the four bearing seats 4008 are extended, so that the four corners of the wood batten 44 can be placed on the four bearing seats 4008. When the wood batten 44 needs to be removed after the alignment of the wood batten 44 is completed, the four bearing seats 4008 are retracted when the mechanical hand holds the wood batten 44. At this time, the bearing seat 4008 is separated from the wood batten 44, so that the flanges on the two sides outside the first side and the second side of the wood batten 44 are not clamped on the bearing seat 4008 when the mechanical hand carries the wood batten 44, which avoids affecting the carrying of the wood batten 44 and damaging the wood batten 44.

The supporting arm 4301 is used for supporting the wood batten 44 when being located at the first position, and is used for avoiding the conveying of the photovoltaic module 34 when being located at the second position.

[0227] In the embodiment, the gear 4303 is provided with a shaft, the lower end of the shaft is connected to the fixed seat 4302 through a bearing 43017, and the upper end is fixedly connected to the supporting arm 4301. The rack 4304 is transversely arranged and engaged with the gear 4303. The output end of the first cylinder 4305 drives the rack 4304 to reciprocate in the horizontal plane, so as to drive the gear 4303 to rotate, and then drive the supporting arm 4301 to rotate in the horizontal plane. The supporting arm 4301 can enter the first position in the Y-direction roller conveying line 38 and the second position outside the Y-direction roller conveying line 38 through transmission.

[0235] In the optional technical scheme of the embodiment, the corner protector gripper 46 is provided in pairs, the driving device 47 comprises a first X-direction driving assembly, a second X-direction driving assembly, and a pair of Y-direction driving assemblies corresponding to the pair of corner protector grippers 46 one by one; the Y-direction driving assembly is drivingly connected to the corner protector gripper 46 and is used to drive the corner protector gripper 46 to reciprocate along the Y direction; the first X-direction driving assembly is drivingly connected to the pair of corner protector grippers 46, the pair of Y-direction driving assemblies, and the second X-direction driving assembly, and is used to drive the pair of corner protector grippers 46, the pair of Y-direction driving assemblies, and the second X-direction driving assembly to extend into or exit the Y-direction roller conveying line 38 along the X direction; the second X-direction driving assembly is drivingly connected to one corner protector gripper 46 and the Y-direction driving assembly corresponding thereto, and is used to drive the pair of corner protector grippers 46 and the pair of Y-direction driving assemblies to relatively approach or move away along the X direction.

[0236] In this embodiment, the corner protector mounting mechanism is provided with two, and is used with the side of the carton along the Y direction roller conveying line 38 conveying direction. The claw arm 4601 is an aluminum alloy profile, and the end is hinged with a claw hand 4602. The first X direction driving assembly and the second X direction driving assembly drive a pair of claw arms 4601 to move to the position opposite to the corner protector buffer device 45. The Y direction driving assembly drives the claw arm 4601 to extend, and the claw hand 4602 adsorbs the corner protector 48 through the first suction cup 4605. Then the Y direction driving assembly drives the claw arm 4601 to retract, and the first X direction driving assembly and the second X direction driving assembly drive a pair of claw arms 4601 to move to the side of the carton, and make the corner protector 48 opposite to the side corner of the carton. The Y direction driving assembly drives the claw arm 4601 to extend. Since the roller 4603 is located at the end of the first section of the claw hand 4602 with larger length, the roller 4603 contacts the carton first. In the process of the claw arm 4601 continuing to extend, the roller 4603 rolls on the side of the carton while the claw hand 4602 rotates, so that the corner protector 48 is installed on the side corner of the carton. It ensures that the corner protector 48 can be accurately and stably fitted on the carton, improves the packaging effect and efficiency. When the claw arm 4601 retracts, the claw hand 4602 resets under the action of the torsional spring 4604. The structure is simple, the reset movement effect is good, the stability is high when the corner protector 48 is installed, and the roller 4603 can stably rotate, avoiding jamming.

The first proximity switch 4608 corresponds to one first suction cup 4605. When the claw hand 4602 twists, in order to avoid excessive twisting, when it twists to the right position, the back of the grabbing surface close to the roller 4603 of the claw hand 4602 abuts against the limiting plane of the limiting end plate 4606, so that the grabbing surface is just in the position parallel to the side of the carton. At this time, the other grabbing surface is also parallel to the adjacent surface of the carton, so that the corner protector 48 can be installed at the side corner of the carton. When the claw hand 4602 resets, in order to avoid excessive resetting, when resetting in the process of rotating through the torsional spring 4604, the limiting plate 4607 on the claw hand 4602 moves towards the end of the claw arm 4601 until abutting, achieving limiting and reaching the reset position at the same time. The structure is simple, the reset effect is good and stable. When the limiting plate 4607 on the claw hand 4602 abuts against the end of the claw arm 4601, the first proximity switch 4608 is opposite to one suction cup. At this time, the first proximity switch 4608 has a signal, showing that the reset is in place, ready for the next time to grab the corner protector 48.
