Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of photovoltaic module production, in particular to a photovoltaic module packing system. BACKGROUND

[0002] At present, when the photovoltaic module packing production line is packing, a grading machine is used in advance to vertically place the photovoltaic module on a wooden tray. Specifically, a packing box is placed on the wooden tray, the packing box is half of a normal packing box, and the top and side of the packing box are open. Then, a suction cup on the grading machine sucks the photovoltaic module, a guide rail drives a mechanical arm and the photovoltaic module to move to the packing box. Then, the mechanical arm rotates the photovoltaic module to adjust the photovoltaic module from a horizontal state to a vertical state. Then, the mechanical arm vertically places the photovoltaic module into the packing box. After all the photovoltaic modules are placed, the photovoltaic modules and the wooden tray are sent to the packing production line for subsequent packing, boxing and film covering steps.

[0003] However, since the packing box cannot effectively limit the photovoltaic module when the grading machine is placing the photovoltaic module, the photovoltaic module often tilts. Thus, when the grading machine places the next photovoltaic module, the next placed photovoltaic module will scratch the previous photovoltaic module, thereby causing damage to the photovoltaic module. SUMMARY

Detailed Implementation

[0080] The technical solution of the present invention will be clearly and completely described below with reference to the embodiments. Obviously, the described embodiments are only some embodiments of the present invention, and 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.

[0081] like Figures 1-48 As shown, one embodiment of the present invention provides a photovoltaic module packaging system, including a photovoltaic module loading line 35, a tray replacement component 36, and a photovoltaic module packaging line 37;

[0082] The photovoltaic module feeding line 35 has at least one unloading end, and the tray changing component 36 is disposed between the unloading end and the feeding end of the photovoltaic module packaging line 37.

[0083] The photovoltaic module loading line 35 is used to transport the iron pallet and the photovoltaic modules on the iron pallet to the unloading end. The pallet changing component 36 is used to flip the photovoltaic modules on the iron pallet onto the wooden pallet. The wooden pallet and the photovoltaic modules on the wooden pallet are transported to the feeding end of the photovoltaic module packaging line 37 through the pallet changing component 36.

[0084] A grading machine is used to stack photovoltaic modules onto iron pallets. The photovoltaic modules and iron pallets are then placed on the photovoltaic module loading line 35, which is equipped with a strapping machine. The strapping machine straps the stacked photovoltaic modules together. The photovoltaic module loading line 35 then transports the photovoltaic modules and iron pallets to the unloading end. The pallet changing component 36 unloads the iron pallets and photovoltaic modules and flips the photovoltaic modules on the iron pallets onto wooden pallets, so that the horizontally stacked photovoltaic modules are flipped to a vertical position. The vertically placed photovoltaic modules are then transported by the iron pallet changing component 36 to the photovoltaic module packaging line 37 for subsequent strapping, boxing, and film coating steps.

[0085] This allows stacked photovoltaic modules to be flipped vertically in one go, preventing scratches between the modules, improving the safety of packaging photovoltaic modules, and greatly reducing production losses.

[0086] Photovoltaic modules 34 are stacked on iron trays by a sorting machine to form a shape like... Figure 30 As shown, the face containing one short side of the photovoltaic module 34 is named the second side 342, and the face containing one long side of the photovoltaic module is named the first side 341.

[0087] Currently, sorting machines are divided into two types according to their functions. The first type of sorting machine grabs the top surface 343 of the photovoltaic module 34 to stack the photovoltaic modules 34 sequentially onto the tray, forming a structure like... Figure 30 The state shown.

[0088] The second type of sorting machine grabs the top surface 343 of the photovoltaic module 34 and then rotates the photovoltaic module 34 so that the first side surface 341 of the photovoltaic module 34 faces downward, making the photovoltaic module 34 vertical.

[0089] It should be noted that during transportation, photovoltaic modules 34 will inevitably experience collisions or vibrations. Therefore, stacking is not used for packaging photovoltaic modules 34, as this would easily cause the glass of the photovoltaic modules 34 to break if a collision or vibration occurs when the photovoltaic modules 34 are stacked. Furthermore, using the second method of sizing and packaging photovoltaic modules would also easily result in damage to the modules.

[0090] In this embodiment, the first type of sorting machine first grabs the top surface 343 of the photovoltaic module 34 to stack the photovoltaic modules 34 sequentially onto the iron tray, forming a structure as shown in the figure. 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.

[0091] 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.

[0092] Because of the different packaging methods for photovoltaic modules, the required shape of the wooden pallets also varies, such as... Figure 31As 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.

[0093] 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.

[0094] 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.

[0095] In this embodiment, the photovoltaic modules 34 are stacked sequentially onto an iron tray using a first sorting machine to form... Figure 30 As shown in the diagram, the iron pallet and photovoltaic module are then fed onto the photovoltaic module feeding line 35. The belt-pulling machine on the photovoltaic module feeding line 35 performs initial belt-pulling on the stacked photovoltaic modules. The iron pallet and photovoltaic module move to the unloading end along with the photovoltaic module feeding line 35. Then, the first wooden pallet 32 ​​is placed on the first pallet flipping mechanism 10. The first pallet flipping mechanism 10 is then used to flip the long side of the photovoltaic module 34 so that the long side of the photovoltaic module 34 is flipped onto the first wooden pallet 32, thus flipping the first side 341 of the photovoltaic module 34 onto the first wooden pallet 32.

[0096] Alternatively, the second wooden pallet 33 can be placed on the second pallet flipping mechanism 11, and the short side of the photovoltaic module 34 can be flipped by the second pallet flipping mechanism 11 to flip the short side of the photovoltaic module 34 onto the second wooden pallet 33, so that the second side 342 of the photovoltaic module 34 can be flipped onto the second wooden pallet 33.

[0097] This allows the stacked photovoltaic modules 34 to be flipped into a vertical position at once, preventing scratches between the photovoltaic modules 34, improving the safety of the photovoltaic modules 34 during packaging, and greatly reducing production losses.

[0098] Preferred, such as Figure 12 and Figure 13 As shown, both the first pallet flipping mechanism 10 and the second pallet flipping mechanism 11 include a ground rail mechanism, a frame 20, at least one telescopic member 19, and multiple insert teeth 22.

[0099] The frame 20 is rotatably mounted on the ground rail mechanism. The frame 20 has a bearing surface for placing wooden pallets. A third roller conveyor mechanism 21 is mounted on the bearing surface for placing and moving wooden pallets. Insert teeth 22 are fixedly mounted on the third roller conveyor mechanism 21 and are perpendicular to the third roller conveyor mechanism 21. The ground rail mechanism is used to drive the frame 20 to move along the length of the ground rail mechanism to insert the insert teeth 22 into the iron pallets. The telescopic member 19 is used to drive the frame 20 to rotate around the connection point between the frame 20 and the ground rail mechanism to flip the photovoltaic modules.

[0100] Furthermore, such as Figure 12 , Figure 13 and Figure 14 As shown, the ground rail mechanism includes a ground rail 17, a transverse frame 18, and a drive component. The transverse frame 18 is slidably mounted on the ground rail 17. The drive component is used to drive the transverse frame 18 to move along the length direction of the ground rail 17. The frame body 20 is hinged to the transverse frame 18. The telescopic component 19 is used to push the frame body 20 to rotate around the hinge point between the frame body 20 and the transverse frame 18.

[0101] In the initial state, such as Figure 13 As shown, the frame 20 is in a horizontal position while the inserter 22 is in a vertical position. The worker places the wooden pallet flat onto the third roller conveyor 21. Then, the telescopic component 19 extends to rotate the frame 20 counterclockwise by 90° around the hinge point between the frame 20 and the transverse frame 18, thus adjusting the frame 20 to a vertical position. Correspondingly, the inserter 22 moves from a vertical position to a horizontal position, and the wooden pallet moves from a horizontal position to a vertical position, achieving the desired effect. Figure 12 The state shown is as follows. Next, the ground rail mechanism drives the transverse frame 18 to move to the left on the ground rail 17. The transverse frame 18 drives the frame body 20 and the insert 22 to move towards the iron pallet, so that the insert 22 is inserted into the iron pallet. Then, the telescopic member 19 shortens to drive the frame body 20 to rotate 90° clockwise around the hinge point between the frame body 20 and the transverse frame 18, so that the frame body 20 flips to a horizontal state, the insert 22 is in a vertical state, and the wooden pallet is adjusted from a vertical state to a horizontal state. The photovoltaic module on the insert 22 flips 90° clockwise along with the frame body 20, so that the photovoltaic module falls onto the wooden pallet. Finally, the ground rail mechanism drives the transverse frame 18 to move to the right to the original position.

[0102] Preferred, such as Figure 14 and Figure 15As shown, a support frame 182 is mounted on the top of the transverse frame 18. Four bearing seats 183 are mounted on the support frame 182. The four bearing seats 183 are divided into two groups, with two bearing seats 183 in each group. These two groups of bearing seats 183 are symmetrical about the support frame 182. One group of bearing seats 183 is located near the front end of the support frame 182, and the other group is located near the rear end of the support frame 182. Figure 14 As shown, a rotating shaft is fixedly connected to each of the two bottom ends of the frame 20, and these two rotating shafts are respectively rotatably installed in two sets of bearing seats 183.

[0103] Furthermore, such as Figure 15 As shown, two sets of bearing seats 184 are installed on the top of the transverse frame 18. Each set of bearing seats 184 has two bearings. The two sets of bearing seats 184 are symmetrically arranged about the transverse frame 18. The telescopic component 19 is a hydraulic cylinder. There are two hydraulic cylinders. The right ends of the two hydraulic cylinders are rotatably installed on the two sets of bearing seats 184 respectively. The left ends of the two hydraulic cylinders are rotatably connected to the frame body 20.

[0104] Optional, such as Figure 17 As shown, three rail plates 171 are installed on the upper surface of the ground rail 17. The rail plates 171 are arranged along the length of the ground rail 17, as follows: Figure 16 As shown, three rows of slide blocks 186 are installed on the lower surface of the transverse frame 18. These three rows of slide blocks 186 correspond one-to-one with three rail plates 171. Each row of slide blocks 186 consists of four slide blocks 186. The slide blocks 186 are slidably installed on the rail plate 171, which can stably support the transverse frame 18 and enable the transverse frame 18 to slide stably on the ground rail 17.

[0105] Preferably, the driving component includes a toothed plate 173, a second motor 181, and a toothed wheel 185, such as Figure 17 As shown, a groove 172 is formed on the upper surface of the ground rail 17 along its length. A toothed plate 173 is fixedly installed in the groove 172, and the width of the toothed plate 173 is smaller than the width of the groove 172. Figure 15 and Figure 16 As shown, the second motor 181 is fixedly mounted on the transverse frame 18. A reducer gearbox is also mounted on the transverse frame 18. The output of the second motor 181 is connected to the input end of the reducer gearbox. The output end of the reducer gearbox faces downward. The toothed gear 185 is fixedly mounted on the output end of the reducer gearbox. The toothed gear 185 extends into the groove 172 and meshes with the toothed plate 173.

[0106] In this way, the second motor 181 drives the toothed wheel 185 to rotate through the reducer gearbox. Since the toothed wheel 185 meshes with the toothed plate 173, the toothed wheel 185 rotates while moving along the toothed plate 173, so that the transverse frame 18 moves along the length direction of the toothed plate 173.

[0107] Preferred, such as Figure 18 As shown, the frame 20 is a rectangular frame. A connecting rod is integrally formed with the frame 20 on both sides of its bottom. Each connecting rod has a fixed rotating shaft, which is rotatably connected to two sets of bearing seats 183. Multiple guide rails 2001 are mounted on the load-bearing surface of the frame 20. Figure 19 This is a structural diagram of the third roller conveyor mechanism 21 in a vertical position. Multiple teeth 22 are mounted side-by-side on the lower surface of the third roller conveyor mechanism 21, and the teeth 22 are perpendicular to the third roller conveyor mechanism 21. A fixed frame 212 is fixedly mounted on the side of the third roller conveyor mechanism 21 facing the frame 20. Three sets of sliding blocks 2002 are mounted on the side of the fixed frame 212 facing the frame 20. These three sets of sliding blocks 2002 correspond to three guide rails 2001, and the sliding blocks 2002 are slidably connected to the guide rails 2001. A third motor 213 for driving the third roller conveyor mechanism 21 is mounted on the fixed frame 212.

[0108] Preferred, such as Figure 18 As shown, two first hydraulic cylinders 2003 are installed at the top of the frame 20, and the rod ends of both first hydraulic cylinders 2003 are fixedly connected to the top of the third roller conveyor mechanism 21. This allows the first hydraulic cylinders 2003 to shorten, pulling the third roller conveyor mechanism 21 upwards. Simultaneously, the sliding block 2002 on the back of the fixed frame 212 slides on the guide rail 2001 on the frame 20, which in turn drives the insert teeth 22 on the third roller conveyor mechanism 21 to rise, thus lifting the photovoltaic modules from the iron tray. This allows the iron tray to be completely separated from the photovoltaic modules, ensuring timely recovery of the iron tray and facilitating the flipping of the photovoltaic modules.

[0109] Preferred, such as Figure 19 As shown, two cylinders 211 are installed on the top of the third roller conveyor mechanism 21. The output ends of the two cylinders 211 face the insert teeth 22. The purpose of setting the cylinders 211 is to fix the wooden pallet. Specifically, as shown... Figure 13 As shown, in the initial state, the frame 20 is in a horizontal state. At this time, the wooden pallet is placed on the third roller conveyor mechanism 21. When the frame 20 rotates counterclockwise, if the wooden pallet is not secured, it will definitely fall off during the rotation of the frame 20.

[0110] Therefore, two cylinders 211 are set up so that after the wooden pallet is placed on the third roller conveyor mechanism 21, the two cylinders 211 can be activated. The two cylinders 211 extend to push the wooden pallet toward the insert tooth 22, so that the wooden pallet is pressed against the insert tooth 22. Since the cylinders 211 always provide a thrust toward the insert tooth 22, the wooden pallet is firmly fixed in place and will not fall off when the third roller conveyor mechanism 21 is rotated.

[0111] Optional, such as Figure 12 As shown, the first pallet flipping mechanism 10 has four teeth 22, and the second pallet flipping mechanism 11 has two teeth 22, which is determined by the type of iron pallet. The number of teeth 22 on the first pallet flipping mechanism 10 and the number of teeth 22 on the second pallet flipping mechanism 11 may vary depending on the size of the iron pallet.

[0112] Preferred, such as Figure 4 As shown, the pallet flipping assembly also includes a second feeding elevator 9, a rotary conveyor 12, and a fourth roller conveyor 13; the first pallet flipping mechanism 10 and the second pallet flipping mechanism 11 are arranged in parallel. The second feeding elevator 9 is used to feed iron pallets and photovoltaic modules. The insert teeth 22 in the first pallet flipping mechanism 10 face the second feeding elevator 9. The rotary conveyor 12 is located at the discharge end of the second feeding elevator 9. The rotary conveyor 12 is used to adjust the conveying angle of the photovoltaic modules so that the short side of the photovoltaic modules faces the second pallet flipping mechanism 11. The fourth roller conveyor 13 is located between the first pallet flipping mechanism 10 and the second pallet flipping mechanism 11, and the fourth roller conveyor 13 is aligned with the feed end of the photovoltaic module packaging line 37.

[0113] In this embodiment, the process of packaging and transporting photovoltaic modules using the first pallet flipping mechanism 10 is as follows: After the first pallet flipping mechanism 10 flips the photovoltaic modules on the second unloading elevator 9 onto the first wooden pallet 32, the ground rail mechanism in the first pallet flipping mechanism 10 moves the photovoltaic modules and the first wooden pallet 32 ​​to the fourth roller conveyor 13, so that the third roller conveyor 21 in the first pallet flipping mechanism 10 is aligned with the fourth roller conveyor 13. At this time, the third roller conveyor 21 in the second pallet flipping mechanism 11 is in a horizontal state, and the second pallet flipping mechanism 11... The feeding end of the third roller conveyor 21 in the first pallet turning mechanism 10 is aligned with the fourth roller conveyor 13, and the discharging end of the third roller conveyor 21 in the second pallet turning mechanism 11 is aligned with the feeding end of the photovoltaic module packaging production line. In this way, the photovoltaic module and the first wooden pallet 32 ​​can be moved from the third roller conveyor 21 in the first pallet turning mechanism 10 to the fourth roller conveyor 13, and then moved from the fourth roller conveyor 13 to the third roller conveyor 21 in the second pallet turning mechanism 11, and then enter the packaging production line through the third roller conveyor 21 in the second pallet turning mechanism 11.

[0114] In this embodiment, the process of packaging and conveying photovoltaic modules using the second pallet flipping mechanism 11 is as follows: After the second unloading elevator 9 removes the iron pallet and photovoltaic modules, the iron pallet and photovoltaic modules continue to move towards the rotary conveyor 12, so that the iron pallet and photovoltaic modules move onto the rotary conveyor 12. The rotary conveyor 12 drives the iron pallet and photovoltaic modules to rotate, so that the short side of the photovoltaic modules faces the second pallet flipping mechanism 11. The second pallet flipping mechanism 11 flips the photovoltaic modules onto the second wooden pallet 33. Then, the ground rail mechanism in the second pallet flipping mechanism 11 drives the photovoltaic modules to move to their original position. At this time, the discharge end of the third roller conveyor mechanism 21 in the second pallet flipping mechanism 11 is aligned with the feed end of the photovoltaic module packaging production line. Then, the third roller conveyor mechanism 21 in the second pallet flipping mechanism 11 is activated, so that the photovoltaic modules and the second wooden pallet 33 move onto the feed end of the photovoltaic module packaging production line.

[0115] The purpose of this layout is to shorten the length of the entire production line, eliminating the need for multiple transport lines. The design is reasonable, resulting in a rational production line layout that saves costs and has a high degree of integration.

[0116] Optional, such as Figure 20As shown, the rotary conveyor 12 includes a base frame 121, a second roller conveying mechanism 124, a driven toothed wheel, a driving toothed wheel 123, and a first motor 122. The driven toothed wheel is rotatably mounted on the base frame 121, the second roller conveying mechanism 124 is mounted on the driven toothed wheel, and the first motor 122 is connected to the driving toothed wheel 123. The driving toothed wheel 123 and the driven toothed wheel mesh with each other. The first motor 122 drives the driving toothed wheel 123 to rotate, thereby driving the driven toothed wheel to rotate and thus driving the second roller conveying mechanism 124 to rotate.

[0117] Preferred, such as Figure 4 As shown, the photovoltaic module packaging system also includes a wooden pallet placement assembly 14, a first wooden pallet storage rack 15, and a second wooden pallet storage rack 16. As mentioned above, there are two types of wooden pallets: a first wooden pallet 32 ​​and a second wooden pallet 33. Therefore, there are also two corresponding wooden pallet storage racks. The first wooden pallet storage rack 15 is used to store the first wooden pallet 32, and the second wooden pallet storage rack 16 is used to store the second wooden pallet 33.

[0118] The pallet placement assembly 14 can grab the first pallet 32 ​​from the first pallet storage rack 15 and place it on the third roller conveyor 21 on the first pallet flipping mechanism 10. The pallet placement assembly 14 can also grab the second pallet 33 from the second pallet storage rack 16 and place the second pallet 33 on the third roller conveyor 21 on the second pallet flipping mechanism 11.

[0119] Specifically, the wooden pallet placement assembly 14 includes an industrial guide rail 141, a support platform 142, a robotic arm 143, and a gripper 23. The industrial guide rail 141 is installed on the ground and is located to the right of the first wooden pallet storage rack 15 and the second wooden pallet storage rack 16. The support platform 142 is slidably mounted on the industrial guide rail 141, and the industrial guide rail 141 can drive the support platform 142 to slide along the industrial guide rail 141. The robotic arm 143 is mounted on the support platform 142, and the gripper 23 is mounted on the robotic arm 143.

[0120] Preferred, such as Figure 24 As shown, the gripping frame 23 includes a frame 231, two gripping arms 232 and a gripping arm drive mechanism. The gripping arm drive mechanism is mounted on the frame 231, and the two gripping arms 232 are slidably mounted on the frame 231. The gripping arm drive mechanism is used to drive the two gripping arms 232 to move closer to each other or further away from each other, thereby gripping or releasing the wooden pallet.

[0121] Optionally, two slide rails are installed at the bottom of the frame 231, and the two slide rails are set along the length of the frame 231. Two sliders are installed on the upper surface of each of the two clamping arms 232. The distance between the two sliders is the same as the distance between the two slide rails. The two sliders are slidably installed on the two slide rails respectively.

[0122] Optionally, the clamping arm drive mechanism includes a fourth motor 233, a transmission belt 234, a first pulley, and a second pulley. Two fixed plates are respectively installed on the left and right sides of the frame 231. The first pulley and the second pulley are rotatably installed on the lower surfaces of the two fixed plates. The transmission belt 234 is driven between the first pulley and the second pulley. The fourth motor 233 is installed on the upper surface of the fixed plate on the right side. The output end of the fourth motor 233 is fixed to the second pulley. The two clamping arms 232 are respectively connected to the opposite sides of the transmission belt 234.

[0123] The second pulley is driven to rotate by the fourth motor 233. The rotation of the second pulley causes the transmission belt 234 to start rotating. Since the two clamping arms 232 are respectively installed on opposite sides of the transmission belt 234, as the transmission belt 234 rotates, the two clamping arms 232 can move away from or closer to each other, thereby gripping or releasing the wooden pallet.

[0124] Optionally, both the first wooden pallet storage rack 15 and the second wooden pallet storage rack 16 include a storage rack, a support mechanism, and a lifting mechanism. The support mechanism is used to support the wooden pallets and is slidably installed inside the storage rack. The lifting mechanism is installed on the storage rack and is used to drive the support mechanism to lift and lower, thereby adjusting the height of the wooden pallets to facilitate the wooden pallet placement component 14 in grasping the wooden pallets. The lifting mechanism can be a traditional screw lifting mechanism or a cylinder lifting mechanism.

[0125] Preferred, such as Figure 21 and Figure 22 As shown, the second feeding elevator 9 includes a frame 901, two columns 902, a first roller conveyor mechanism 903, and a lifting mechanism. The first roller conveyor mechanism 903 is located between the frame 901 and the two columns 902. Multiple second vertical rails are installed on the right side of the frame 901, and a third vertical rail is installed on each column 902. Multiple lifting blocks matching the second vertical rails are fixedly installed on the left side of the first roller conveyor mechanism 903, and two lifting blocks matching the second vertical rails are fixedly installed on the right side of the first roller conveyor mechanism 903.

[0126] In this way, the left side of the first roller conveyor mechanism 903 can be slidably connected to the second vertical rail on the upright 901, and the right side of the first roller conveyor mechanism 903 can be slidably connected to the third vertical rail on the column 902.

[0127] Furthermore, such as Figure 22As shown, the lifting mechanism includes a movable frame, a second hydraulic cylinder 904, and a pull belt 905. The movable frame includes a crossbar 906, a fixed frame 907, two fixed plates, and a rotating rod 908. A fixed plate is fixedly connected to each end of the crossbar 906, perpendicular to the crossbar 906. A first slider 910 is fixedly mounted on each fixed plate. Two first vertical rails 909 are vertically mounted on the upright 901, and the two first sliders 910 are slidably mounted on these two first vertical rails 909 respectively. The fixed frame 907 is a portal frame, with both ends welded to the crossbar 906, and the rotating rod 908 is rotatably mounted inside the fixed frame 907. The bottom of the second hydraulic cylinder 904 is bolted to the bottom of the upright 901, and the top of the second hydraulic cylinder 904 is fixedly mounted to the fixed frame 907. One end of the pull belt 905 is fixedly mounted to the bottom of the upright 901, and the other end passes through the rotating rod 908 and is fixed to the side of the first roller conveyor mechanism 903.

[0128] When the second hydraulic cylinder 904 extends, it pushes the moving frame to move up along the height direction of the upright 901. Since one end of the pull belt 905 is fixedly installed at the bottom of the upright 901, and the other end passes through the rotating rod 908 and is fixed to the side of the first roller conveyor mechanism 903, and the first roller conveyor mechanism 903 can slide on the upright 901, as the moving frame rises, the length of the end of the pull belt 905 connected to the first roller conveyor mechanism 903 gradually decreases, thereby pulling the first roller conveyor mechanism 903 to rise.

[0129] Optionally, multiple through-beam sensors are installed on the first roller conveyor mechanism 903. These sensors are used to detect the positions of the iron trays and photovoltaic modules on the first roller conveyor mechanism 903, facilitating their positioning. Furthermore, if the through-beam sensors detect the presence of iron trays and photovoltaic modules on the first roller conveyor mechanism 903, it indicates that the tray flipping assembly is in operation.

[0130] Preferred, such as Figure 2 As shown, the photovoltaic module feeding line 35 includes a first conveyor line 2, a first roller conveyor 5, and a second conveyor line 6 connected in sequence. The second conveyor line 6 has two layers, and the unloading end is located on the upper layer of the second conveyor line 6.

[0131] Let's look again. Figure 6 , Figure 7 and Figure 8As shown, the upper layer of the second conveyor line 6 is sequentially equipped with a fourth chain roller conveyor mechanism 602, a fifth chain roller conveyor mechanism 603, and a sixth chain roller conveyor mechanism 604. The fourth chain roller conveyor mechanism 602 is located at the tail end of the second conveyor line 6, the sixth chain roller conveyor mechanism 604 is located at the feed end of the second conveyor line 6, and the fifth chain roller conveyor mechanism 603 and the fourth chain roller conveyor mechanism 602 are both discharge ends. The discharge end of the first roller conveyor 5 is aligned with the sixth chain roller conveyor mechanism 604.

[0132] Photovoltaic modules and iron pallets are fed from the inlet end of the first conveyor line 2. The first conveyor line 2 transports the photovoltaic modules and iron pallets to the first roller conveyor 5. The first roller conveyor 5 then transports the photovoltaic modules and iron pallets to the sixth chain roller conveyor mechanism 604. The photovoltaic modules and iron pallets then move with the second conveyor line 6 to the fifth chain roller conveyor mechanism 603. If the pallet flipping component at the fifth chain roller conveyor mechanism 603 is idle, the photovoltaic modules and iron pallets are unloaded from there. If the pallet flipping component at the fifth chain roller conveyor mechanism 603 is in operation, the second conveyor line 6 continues to transport the photovoltaic modules and iron pallets to the fourth chain roller conveyor mechanism 602. The photovoltaic modules are then unloaded at the fourth chain roller conveyor mechanism 602, where the pallet flipping component performs the flipping operation.

[0133] This improves the packaging efficiency of photovoltaic modules. Two sets of pallet flipping components can be set to work simultaneously, reducing the waiting time for iron pallets and photovoltaic modules on the second conveyor line 6.

[0134] Preferred, such as Figure 5 As shown, the first conveyor line 2 includes multiple first conveyor frames 201 arranged in sequence. A first chain roller conveyor mechanism 203 is installed on the leftmost first conveyor frame 201, and a second chain roller conveyor mechanism 204 is installed on the rightmost first conveyor line 2. A first chain conveyor mechanism 202 is installed on each first conveyor line 2.

[0135] A feeding elevator 1 is provided in front of the first conveyor frame 201 on the far left. The feeding elevator 1 is used to feed the iron pallet and photovoltaic module onto the first chain roller conveyor mechanism 203. Then the first chain conveyor mechanism 202 conveys the photovoltaic module onto the first chain conveyor mechanism 202. After being conveyed by multiple first chain conveyor mechanisms 202, the photovoltaic module is conveyed onto the second chain roller conveyor mechanism 204.

[0136] Preferred, such as Figure 2As shown, the photovoltaic module loading line 35 also includes a barcode scanning component 24 and a photovoltaic module recycling line 4. The barcode scanning component 24 is installed on a first conveyor frame 201 on the right side of the first chain roller conveyor mechanism 203. The photovoltaic module recycling line 4 includes a support frame 401, a third chain roller conveyor mechanism 403, a second roller conveyor 402, and a first unloading elevator 3.

[0137] The support frame 401 is located near the feed end of the second conveyor line 6. The third chain roller conveyor mechanism 403 is installed on the support frame 401. The feed end of the second roller conveyor 402 is connected to the third chain roller conveyor mechanism 403. The first discharge elevator 3 is located at the discharge end of the second roller conveyor 402.

[0138] When the photovoltaic module moves to the barcode scanning component 24, the scanning component 24 scans the barcode on the photovoltaic module to obtain the barcode information. If the barcode is duplicated or damaged, the scanning component 24 uploads the error information to the central control system. When the photovoltaic module moves to the feeding end of the second conveyor line 6, it moves to the right side of the feeding end of the second conveyor line 6 onto the third chain roller conveyor mechanism 403. Then, the third chain roller conveyor mechanism 403 conveys the photovoltaic module onto the second roller conveyor 402. Finally, the first unloading elevator 3 removes the problematic photovoltaic module from the discharge end of the second roller conveyor 402. This allows for the recycling of problematic photovoltaic modules, enabling staff to immediately check the barcodes and improving production efficiency.

[0139] Optional, such as Figure 25 As shown, the barcode scanning assembly 24 includes a gantry frame, a crossbeam 241, a lifting mechanism, a traversing mechanism, and a barcode scanning mechanism 242. The crossbeam 241 is slidably mounted on the gantry frame. The lifting mechanism is used to drive the crossbeam 241 to rise and fall. The barcode scanning mechanism 242 is slidably mounted on the crossbeam 241. The traversing mechanism is used to drive the barcode scanning mechanism 242 to move along the length of the crossbeam 241.

[0140] In this way, the lifting mechanism drives the crossbeam 241 to rise and fall to adjust the height of the scanning mechanism 242 so that the scanning mechanism 242 is at the same height as the barcode on the side of the photovoltaic module. Then, the horizontal movement mechanism drives the scanning mechanism 242 to move left and right, so that the scanning mechanism 242 is facing the barcode.

[0141] It's important to know that the placement of the barcode on the photovoltaic module is fixed, so you only need to set the travel of the horizontal and vertical movement mechanisms to quickly position the barcode.

[0142] Optionally, the lifting mechanism can be a belt-driven lifting mechanism or a screw lifting mechanism. The traversing mechanism can be a linear module.

[0143] Optionally, the scanning mechanism 242 includes a camera that acquires barcode information, or it can use a barcode scanner or barcode reader, as long as it can read barcode information.

[0144] Preferred, combined Figure 6 and Figure 7 The second conveyor line 6 includes a plurality of second conveyor frames 601 arranged in sequence. The second conveyor frame 601 has two layers, upper and lower. The sixth chain roller conveyor mechanism 604 is installed on the rightmost second conveyor frame 601. The sixth chain roller conveyor mechanism 604 is connected to the first roller conveyor 5, and at the same time, the sixth chain roller conveyor mechanism 604 is also connected to the third chain roller conveyor mechanism 403.

[0145] It should be noted that the first chain roller conveyor mechanism 203, the second chain roller conveyor mechanism 204, the third chain roller conveyor mechanism 403, and the sixth chain roller conveyor mechanism 604 have the same structure, all of which include a chain conveyor structure and a roller conveyor structure, and the conveying direction of the roller conveyor structure is perpendicular to that of the chain conveyor structure.

[0146] like Figure 5 As shown, the conveying direction of the roller conveying structure in the sixth chain roller conveyor 604 is the same as the conveying direction of the first roller conveyor 5. The conveying direction of the chain conveying structure in the sixth chain roller conveyor 604 is the same as the conveying direction of the chain conveying structure in the third chain roller conveyor 403. The conveying direction of the roller conveying structure in the third chain roller conveyor 403 is the same as the conveying direction of the second roller conveyor 402. The conveying direction of the chain conveying structure in the second chain roller conveyor 204 is the same as the conveying direction of the first chain conveyor 202. The conveying direction of the roller conveying mechanism in the second chain roller conveyor 204 is the same as the conveying direction of the first roller conveyor 5.

[0147] When the photovoltaic module moves onto the sixth chain roller conveyor 604, if there is a problem with the barcode on the photovoltaic module, the chain conveyor on the sixth chain roller conveyor 604 will open to drive the photovoltaic module toward the support frame 401, so as to move the photovoltaic module onto the third chain roller conveyor 403. At the same time, the chain conveyor on the third chain roller conveyor 403 will operate so that the entire photovoltaic module enters the third chain roller conveyor 403. Finally, the roller conveyor on the third chain roller conveyor 403 will open to transport the photovoltaic module onto the second roller conveyor 402.

[0148] Preferred, such as Figure 6As shown, a fourth chain roller conveyor mechanism 602 is installed on the upper layer of the second conveyor frame 601 at the far left, and a seventh chain roller conveyor mechanism 606 is installed on the lower layer of the second conveyor frame 601.

[0149] A fifth chain roller conveyor mechanism 603 is installed on the upper layer of one of the middle second conveyor frames 601, and an eighth chain roller conveyor mechanism 607 is installed on the upper layer of the second conveyor frame 601. A second chain conveyor mechanism 605 is installed on the upper layer of the two second conveyor frames 601 between the fifth chain roller conveyor mechanism 603 and the sixth chain roller conveyor mechanism 604.

[0150] Furthermore, a second chain conveyor 605 is installed on the upper layer of each of the four second conveyor frames 601 between the fifth chain roller conveyor 603 and the fourth chain roller conveyor 602, and a third chain conveyor 608 is installed on the lower layer of each of the four second conveyor frames 601.

[0151] Thus, a pallet flipping assembly is installed on the back of the fifth chain roller conveyor 603 and the back of the fourth chain roller conveyor 602, respectively.

[0152] That is, both the fifth chain roller conveyor 603 and the fourth chain roller conveyor 602 are the unloading ends.

[0153] Preferred, such as Figure 7 , Figure 8 and Figure 9 As shown, the photovoltaic module feeding and conveying system also includes a third conveyor line 8, which includes multiple third conveyor frames 801 arranged in sequence. The third conveyor line 8 is located between the first conveyor line 2 and the second conveyor line 6, and the second conveyor line 6 and the third conveyor line 8 are parallel to each other.

[0154] Each third conveyor 801 has an upper and a lower layer, from... Figure 2 From the perspective of [the device], the upper layer of the rightmost third conveyor frame 801 is equipped with the ninth chain roller conveyor mechanism 803, and the lower layer of the rightmost third conveyor frame 801 is equipped with the tenth chain roller conveyor mechanism 804. The ninth chain roller conveyor mechanism 803 is connected to the fifth chain roller conveyor mechanism 603, and the photovoltaic modules on the fifth chain roller conveyor mechanism 603 can be moved onto the ninth chain roller conveyor mechanism 803. The tenth chain roller conveyor mechanism 804 is connected to the eighth chain roller conveyor mechanism 607, and the iron tray on the eighth chain roller conveyor mechanism 607 can be moved onto the tenth chain roller conveyor mechanism 804.

[0155] In addition to the third conveyor frame 801 where the ninth chain roller conveyor mechanism 803 is located, the upper layer of the remaining third conveyor frames 801 is equipped with a fourth chain conveyor mechanism 802, and the lower layer of the remaining third conveyor frames 801 is equipped with a fifth chain conveyor mechanism 805.

[0156] In this way, the photovoltaic modules and iron trays move from the sixth chain roller conveyor 604 to the fifth chain roller conveyor 603. If the photovoltaic module flipping mechanism at the fifth chain roller conveyor 603 is idle at this time, the photovoltaic modules will stop at the fifth chain roller conveyor 603, and then the second unloading elevator 9 at the fifth chain roller conveyor 603 will remove the photovoltaic modules from the fifth chain roller conveyor 603. If the photovoltaic module flipping mechanism at the fifth chain roller conveyor 603 is active at this time, the photovoltaic modules on the fifth chain roller conveyor 603 will continue to move to the fourth chain roller conveyor 602.

[0157] If both photovoltaic module flipping mechanisms are operational, when the photovoltaic module moves to the fifth chain roller conveyor 603, the roller conveying structure in the fifth chain roller conveyor 603 opens to move the photovoltaic module towards the ninth chain roller conveyor 803, so that the photovoltaic module is temporarily stored on the ninth chain roller conveyor 803. When the photovoltaic module flipping mechanism at the fifth chain roller conveyor 603 is idle, the ninth chain roller conveyor 803 moves the photovoltaic module onto the fifth chain roller conveyor 603, and then the second unloading elevator 9 located at the fifth chain roller conveyor 603 unloads the module.

[0158] This adds a temporary storage function to temporarily store photovoltaic modules, which is a reasonable design and improves work efficiency.

[0159] It should be noted that there are two recycling paths for the iron pallet located at the eighth chain roller conveyor mechanism 607. In the first case, the roller conveyor structure on the eighth chain roller conveyor mechanism 607 opens to transport the iron pallet to the tenth chain roller conveyor mechanism 804. Subsequently, the roller conveyor structure on the tenth chain roller conveyor mechanism 804 opens to transport the photovoltaic module to the fifth chain conveyor mechanism 805. The photovoltaic module moves to the fourth conveyor line 7 along with the fifth chain conveyor mechanism 805.

[0160] In the second method, the chain conveying mechanism on the eighth chain roller conveyor 607 is opened to convey the photovoltaic module to the third chain conveyor 608. The photovoltaic module moves with the third chain conveyor 608 to the seventh chain roller conveyor 606. Then, the roller conveying structure on the seventh chain roller conveyor 606 is opened to feed the photovoltaic module into the fourth conveyor line 7.

[0161] Two recycling paths were designed to simultaneously recycle more iron pallets, thus improving the recycling efficiency of iron pallets.

[0162] It should be noted that the iron pallet located at the seventh chain roller conveyor mechanism 606 is recycled in the following manner: after the photovoltaic module enters the seventh chain roller conveyor mechanism 606, the roller conveyor structure in the seventh chain roller conveyor mechanism 606 is opened to transport the iron pallet to the fourth conveyor line 7, and then it is moved away with the fourth conveyor line 7.

[0163] Preferred, such as Figure 7 and Figure 10 As shown, the fourth conveyor line 7 includes an eleventh chain roller conveyor mechanism 701, a third roller conveyor 702, and a third discharge elevator 703 connected in sequence. The eleventh chain roller conveyor mechanism 701 is connected to the seventh chain roller conveyor mechanism 606. Specifically, the feed end of the roller conveyor structure in the eleventh chain roller conveyor mechanism 701 is close to the discharge end of the roller conveyor structure in the seventh chain roller conveyor mechanism 606. The conveying direction of the chain conveyor structure in the eleventh chain roller conveyor mechanism 701 is consistent with the conveying direction of the fifth chain conveyor mechanism 805, and the chain conveyor structure in the eleventh chain roller conveyor mechanism 701 is aligned with the fifth chain conveyor mechanism 805. The third discharge elevator 703 is located at the discharge end of the third roller conveyor 702.

[0164] In this way, the iron pallet in the fifth chain conveyor mechanism 805 can be conveyed to the chain conveyor structure in the eleventh chain roller conveyor mechanism 701. After the iron pallet stops, the roller conveyor structure in the eleventh chain roller conveyor mechanism 701 opens to convey the iron pallet to the third roller conveyor 702.

[0165] Furthermore, the iron pallet entering the seventh chain roller conveyor 606 can be conveyed to the eleventh chain roller conveyor 701. Then, the roller conveyor structure on the eleventh chain roller conveyor 701 opens to convey the iron pallet to the third roller conveyor 702, and finally the iron pallet is removed from the third unloading elevator 703.

[0166] It should be noted that the first chain roller conveyor 203, the second chain roller conveyor 204, the third chain roller conveyor 403, the fourth chain roller conveyor 602, the fifth chain roller conveyor 603, the sixth chain roller conveyor 604, the seventh chain roller conveyor 606, the eighth chain roller conveyor 607, the ninth chain roller conveyor 803, the tenth chain roller conveyor 804, and the eleventh chain roller conveyor 701 are completely identical.

[0167] Preferably, the chain-roller conveyor mechanism includes a chain conveyor structure and a roller conveyor structure. The chain conveyor structure includes three chain conveyor modules, namely chain conveyor module one 25, chain conveyor module two 26 and chain conveyor module three 27, and the roller conveyor structure includes two roller conveyor modules, namely roller conveyor module one 28 and roller conveyor module two 29.

[0168] The three chain conveyor modules are arranged in parallel. Roller conveyor module 1 28 is located between chain conveyor module 1 25 and chain conveyor module 2 26. Roller conveyor module 2 29 is located between chain conveyor module 2 26 and chain conveyor module 3 27. The conveying direction of the chain conveyor module is perpendicular to the conveying direction of the roller conveyor module, and the upper surface of the chain conveyor module is flush with the upper surface of the roller conveyor module.

[0169] When the photovoltaic module or iron pallet moves from the three chain conveyor modules to the middle position of the chain roller conveyor mechanism, the three chain conveyor modules stop working, and then the two roller conveyor modules operate to move the photovoltaic module or iron pallet out of the chain roller conveyor mechanism.

[0170] Furthermore, the chain roller conveyor mechanism also includes a roller drive mechanism 30 and a chain drive mechanism 31. The roller drive mechanism 30 is used to drive two roller conveyor modules to operate synchronously, and the chain drive mechanism 31 is used to drive three chain conveyor modules to operate synchronously.

[0171] like Figure 10 As shown, the roller drive mechanism 30 includes a fifth motor 3001, a drive sprocket 3002, a sprocket shaft, a driven sprocket 3003, and a drive chain 3004. The fifth motor 3001 is installed at the bottom of the second roller conveyor module 29, and the drive sprocket 3002 is installed at the output end of the fifth motor 3001. A base plate is installed at the bottom of the first roller conveyor module 28, and the sprocket shaft is rotatably mounted on the base plate via two bearing seats. The driven sprocket 3003 is fixedly mounted on the sprocket shaft.

[0172] It should be noted that a first sprocket is also installed on the sprocket shaft. This sprocket is located on 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 by a driving chain 3004. Both roller conveyor module 1 28 and roller conveyor module 2 29 include multiple rollers. A second sprocket is installed at the same end of each roller. The multiple second sprockets are connected by a first chain, and a second sprocket is connected to a first sprocket by a second chain.

[0173] In this way, the fifth motor 3001 drives the drive sprocket 3002 to rotate, and the drive sprocket 3002 drives the driven sprocket 3003 to rotate through the drive chain 3004, thereby driving the sprocket shaft to rotate. The rotation of the sprocket shaft drives the first sprocket to rotate synchronously, and the rotation of the first sprocket drives the second sprocket to rotate, thereby driving the second sprocket on a roller to rotate. The multiple second sprockets are connected to each other through the first chain drive, so that multiple rollers rotate synchronously.

[0174] Preferred, such as Figure 11 As shown, the chain drive mechanism 31 includes a sixth motor 311, a rotating shaft 312, a first fixed sprocket, a second fixed sprocket 313, and three third fixed sprockets.

[0175] The output end of the sixth motor 311 is equipped with a first fixed sprocket, and a second fixed sprocket 313 and three third fixed sprockets are fixedly installed on the rotating shaft 312. The three fixed sprockets are respectively connected to the three chain conveyor structures through chain drive. The first fixed sprocket and the second fixed sprocket 313 are connected by a fixed chain drive. In this way, the sixth motor 311 drives the first fixed sprocket to rotate, thereby driving the rotating shaft 312 and the three third fixed sprockets to rotate synchronously, and finally synchronously driving the three chain conveyor structures to work synchronously.

[0176] In summary, when packaging photovoltaic modules, this packaging production system first uses a sorting machine to stack the photovoltaic modules on iron pallets. Then, barcodes are affixed to the photovoltaic modules. Next, a forklift is used to place the iron pallets and photovoltaic modules onto the loading elevator 1. The loading elevator 1 loads the iron pallets and photovoltaic modules onto the first chain roller conveyor 203. The first chain roller conveyor 203 transports the iron pallets and photovoltaic modules to the first conveyor line 2. The photovoltaic modules and iron pallets pass under the barcode scanning component 24. The barcode scanning component 24 then scans the barcode on the photovoltaic module and obtains the barcode information, which is then uploaded to the central control system. The central control system determines the specific packaging method required for the current photovoltaic module. If the barcode is duplicated or damaged, the barcode scanning component 24 uploads the error information to the central control system.

[0177] Next, the photovoltaic modules are bundled together by a preliminary binding machine at point 2 of the first conveyor line.

[0178] After initial conveying, the photovoltaic modules and iron pallets move from the second chain roller conveyor 204 to the first roller conveyor 5, and then via the first roller conveyor 5 to the sixth chain roller conveyor 604. If there is a problem with the barcode, the sixth chain roller conveyor 604 will then convey the photovoltaic modules and iron pallets to the third chain roller conveyor 403, and then via the second roller conveyor 402, they will be unloaded from the first unloading elevator 3. If the barcode is correct, the sixth chain roller conveyor 604 will then convey the photovoltaic modules and iron pallets to the second chain conveyor 605 and continue moving to the fifth chain roller conveyor 603.

[0179] If the pallet tilting assembly at the fifth chain roller conveyor 603 is idle, the second unloading elevator 9 will unload the material. If the pallet tilting assembly at the fifth chain roller conveyor 603 is active, the photovoltaic module and the iron pallet will continue to move onto the fourth chain roller conveyor 602.

[0180] Next, the lifting mechanism in the second feeding elevator 9 drives the first roller conveyor 903 to rise so that the first roller conveyor 903 is level with the second conveyor line 6. Then, the photovoltaic module and the iron pallet are conveyed to the first roller conveyor 903. The first roller conveyor 903 is opened to completely move the photovoltaic module and the iron pallet onto the first roller conveyor 903.

[0181] Based on the barcode information obtained from the central control system, if the information indicates that the long side of the photovoltaic module should be flipped, the first pallet flipping mechanism 10 will start working. The first pallet flipping mechanism 10 will flip the photovoltaic module from the second unloading elevator 9 onto the first wooden pallet 32. Then, the ground rail mechanism in the first pallet flipping mechanism 10 will move the photovoltaic module and the first wooden pallet 32 ​​to the fourth roller conveyor 13, aligning the third roller conveyor 21 in the first pallet flipping mechanism 10 with the fourth roller conveyor 13. At this time, the third roller conveyor 21 in the second pallet flipping mechanism 11 will be in a horizontal state. The feeding end of the third roller conveyor 21 in the second pallet flipping mechanism 11 is aligned with the fourth roller conveyor 13, and the discharging end of the third roller conveyor 21 in the second pallet flipping mechanism 11 is aligned with the feeding end of the photovoltaic module packaging production line. The photovoltaic module and the first wooden pallet 32 ​​can then be moved from the third roller conveyor 21 in the first pallet flipping mechanism 10 to the fourth roller conveyor 13, and then moved from the fourth roller conveyor 13 to the third roller conveyor 21 in the second pallet flipping mechanism 11, and then entered the packaging production line via the third roller conveyor 21 in the second pallet flipping mechanism 11.

[0182] If the information obtained is to flip the short side of the photovoltaic module, then after the second unloading elevator 9 removes the iron pallet and photovoltaic module, the iron pallet and photovoltaic module continue to move towards the rotary conveyor 12, so that the iron pallet and photovoltaic module move onto the rotary conveyor 12. The rotary conveyor 12 drives the iron pallet and photovoltaic module to rotate, so that the short side of the photovoltaic module faces the second pallet flipping mechanism 11. The second pallet flipping mechanism 11 flips the photovoltaic module onto the second wooden pallet 33. Then, the ground rail mechanism in the second pallet flipping mechanism 11 drives the photovoltaic module to move back to its original position. At this time, the discharge end of the third roller conveyor mechanism 21 in the second pallet flipping mechanism 11 is aligned with the feed end of the photovoltaic module packaging production line. Then, the third roller conveyor mechanism 21 in the second pallet flipping mechanism 11 is activated, so that the photovoltaic module and the second wooden pallet 33 move onto the feed end of the photovoltaic module packaging production line.

[0183] The photovoltaic module packaging line 37 will be described in detail below:

[0184] Preferred, such as Figure 32 As shown, the photovoltaic module packaging line 37 includes: a Y-axis roller conveyor 38, a first strapping mechanism 56, a packaging mechanism, a second strapping mechanism, a third strapping mechanism, a wooden protective rib 44 mounting mechanism, a corner protector 48 mounting mechanism, and a film-coating mechanism; along the conveying direction of the Y-axis roller conveyor 38, the first strapping mechanism 56, the packaging mechanism, the second strapping mechanism, the third strapping mechanism, and the film-coating mechanism are arranged sequentially; the Y-axis roller conveyor 38 is used to convey a wooden pallet 64 containing photovoltaic modules 34, the first strapping mechanism 56 is used to strap the photovoltaic modules 34 and the wooden pallet 64 with the first protective strap, and the packaging mechanism is used to package the photovoltaic modules 34 with outer cardboard boxes. The second strapping mechanism is used to strap the cardboard box and wooden pallet 64 with a second protective strap, the third strapping mechanism is used to strap the cardboard box with a third protective strap, and the film-coating mechanism is used to coat the cardboard box with film. The wooden baffle 44 mounting mechanism and the corner protector 48 mounting mechanism are both located at the third strapping mechanism. 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 baffle 44 mounting mechanism is used to install the wooden baffle 44 before the third strapping mechanism straps the cardboard box with a third protective strap. When the photovoltaic module 34 is in the second placement mode, the corner protector 48 mounting mechanism is used to install the corner protector 48 before the third strapping mechanism straps the cardboard box with a third protective strap.

[0185] During the packaging process of photovoltaic modules 34, the wooden pallet 64 containing the photovoltaic modules 34 is sequentially conveyed to the first strapping mechanism 56, the packaging mechanism, the second strapping mechanism, the third strapping mechanism, and the laminating mechanism via the Y-axis roller conveyor 38. When the photovoltaic modules 34 conveyed by the Y-axis roller conveyor 38 are in the first placement configuration, the wooden protective rib 44 installation mechanism first attaches the wooden protective rib 44 to the side of the carton, and then the third strapping mechanism applies a third protective strap to the carton and the wooden protective rib 44. When the photovoltaic modules 34 conveyed by the Y-axis roller conveyor 38 are in the second placement configuration... At the same time, the corner protector 48 installation mechanism first installs the corner protector 48 onto the side corner of the carton, and the third strapping mechanism then straps the carton and the corner protector 48 with a third strap, so as to pack the photovoltaic modules 34 with two different placement forms, thereby improving the adaptability of the photovoltaic module packing line 37. Compared with the method of packing the photovoltaic modules 34 with two different placement forms separately through two packing lines, it can save space and cost. At the same time, the photovoltaic module packing line 37 provided by the present invention operates smoothly and can automatically pack large-size photovoltaic module 34 products, saving manpower and packing efficiency.

[0186] In this embodiment, the photovoltaic module 34 is placed vertically, and the first placement is with the short side down, and the second placement is with the long side down. The third tape-attaching mechanism includes two horizontal tape-attaching machines 63, one corresponding to the wooden joist 44 installation mechanism and the other corresponding to the corner protector 48 installation mechanism.

[0187] In the optional technical solution of this embodiment, the wooden guardrail 44 installation mechanism includes a first Y-direction ground rail 39, a wooden guardrail alignment device 40, a pair of robotic arms 41, a pair of wooden guardrail buffer devices 42, and two pairs of support devices 43; the first Y-direction ground rail 39 is disposed on one side of the Y-direction roller conveyor line 38, and the pair of robotic arms 41 are both slidably disposed on the first Y-direction ground rail 39; the wooden guardrail alignment device 40 and the pair of wooden guardrail buffer devices 42 are both disposed on the side of the first Y-direction ground rail 39 away from the Y-direction roller conveyor line 38, and the wooden guardrail alignment device 40 is located between the pair of wooden guardrail buffer devices 42; the support devices 43 are disposed on the Y-direction roller conveyor line 38, and each pair of support devices 43 is located on both sides of the Y-direction roller conveyor line 38, and each pair of support devices 43 is used to support one wooden guardrail 44.

[0188] In this embodiment, the wooden guard 44 is frame-shaped with a supporting diagonal beam between one of its diagonals. The left and right sides have flanges, which are fastened together with the flanges to the side corners of the carton. The wooden guard 44 is stacked on a pallet and placed in the wooden guard buffer device 42. A pair of robotic arms 41 are paired with a pair of wooden guard buffer devices 42. The robotic arms 41 grab the wooden guard 44 in their corresponding wooden guard buffer devices 42 and first place it on the wooden guard straightening device 40 for straightening. Then, the straightened wooden guard 44 is picked up. The pair of robotic arms 41 respectively install the wooden guard 44 on the opposite sides of the carton along the Y-direction roller conveyor line 38. At the same time, two pairs of supporting devices 43 support two wooden guard 44 respectively, and the robotic arms 41 are removed. The supporting devices 43 support the lower side of the wooden guard 44 to avoid affecting the transverse strapping.

[0189] In the optional technical solution of this embodiment, the wooden guardrail straightening device 40 includes a drive assembly, four load-bearing assemblies, a first straightening seat 4009, and a second straightening seat 40010. The first straightening seat 4009 and the second straightening seat 40010 are arranged opposite to each other, and the first straightening seat 4009 is provided with a first through groove, and the second straightening seat 40010 is provided with a second through groove. The first through groove and the second through groove are parallel. Load-bearing assemblies are provided on both the left and right sides of the first straightening seat 4009, and load-bearing assemblies are provided on both the left and right sides of the second straightening seat 40010. The lines connecting the four load-bearing assemblies form a rectangle. The four corners of the wooden guardrail 44 are shaped and used to support the wooden guardrail 44; the drive assembly is used to drive the first alignment seat 4009 and the second alignment seat 40010 to rotate synchronously, and the first alignment seat 4009 and the second alignment seat 40010 can move closer to each other or further away from each other; the wooden guardrail 44 has a first side and a second side, and the first alignment seat 4009 and the second alignment seat 40010 can abut against the first side and the second side respectively by moving closer to each other, and the first side can enter the first through groove, and the first alignment seat 4009 and the second alignment seat 40010 can enter the second through groove by rotating synchronously.

[0190] In use, the first alignment seat 4009 and the second alignment seat 40010 are positioned far apart. The four corners of the wooden guardrail 44 are placed on the four supporting components. The first alignment seat 4009 and the second alignment seat 40010 are brought closer together until they abut against the first and second sides respectively. At the same time, the first side enters the first through groove. Since the first and second sides are not on the same plane, the second side does not enter the second through groove, meaning the second through groove intersects with the second side. At this time, the first alignment seat 4009 and the second alignment seat 40010 are driven to rotate synchronously by the drive component. Because the first and second sides are far apart, the first alignment seat... The rotational force generated by the rotation of 4009 on the first side will not cause the second side to rotate. At the same time, the second straightening seat 40010 rotates to make the second through groove rotate from the position intersecting with the second side to the position parallel and facing the second side. At this time, under the action of the force of the first straightening seat 4009 and the second straightening seat 40010 approaching each other, the second side enters the second through groove. Since the first through groove and the second through groove are parallel, the first side in the first through groove is parallel to the second side in the second through groove, thereby realizing the straightening of the wooden guard 44, making the wooden guard 44 as a whole in the same plane. The structure is simple, saves manpower and has a good straightening effect.

[0191] In the optional technical solution of this embodiment, a pair of grippers 4002 are also included. The pair of grippers 4002 are respectively disposed on the left and right sides of the first alignment seat 4009. The grippers 4002 are used to grip the first side, and by gripping the first side, the first side can enter the first through groove.

[0192] In this embodiment, the clamping space of the gripper 4002 is greater than the width of the first through slot. When the first alignment seat 4009 and the second alignment seat 40010 approach each other until they abut against the first side and the second side respectively, the first side can enter the clamping space of the gripper 4002 because the clamping space of the gripper 4002 is greater than the width of the first through slot. The gripper 4002 clamps the first side. Since a pair of grippers 4002 are respectively arranged on the left and right sides of the first alignment seat 4009, the pair of grippers 4002 simultaneously clamp the first side, making the first side straight. When the alignment seats 40010 approach each other until they abut against the first side and the second side respectively, even if the first side is not inserted into the first through groove but is crossed with it, after the first side is straightened by the clamping of a pair of jaws 4002, the first side is parallel and directly opposite the first through groove. At this time, under the force of the first alignment seats 4009 and the second alignment seats 40010 approaching each other, the first side enters the first through groove. Before the drive assembly drives the first alignment seats 4009 and the second alignment seats 40010 to rotate synchronously, the jaws 4002 release the first side to prevent the jaws 4002 from driving the first side to rotate. It should be noted that the width of the first through groove is slightly greater than the thickness of the first side to facilitate the entry of the first side. The width of the second through groove is also slightly greater than the thickness of the second side to facilitate the entry of the second side. When the gripper 4002 grips the first side, the gripping space of the gripper 4002 is slightly greater than the thickness of the first side, so that the first side can enter the first through groove under the force of the first aligning seat 4009 and the second aligning seat 40010 approaching each other.

[0193] In the optional technical solution of this embodiment, a first transmission seat and a second transmission seat are also included. The driving component is connected to the first transmission seat and the second transmission seat and is used to drive the first transmission seat and the second transmission seat to rotate synchronously. The first alignment seat 4009 and the gripper 4002 are both disposed on the first transmission seat, and the second alignment seat 40010 is disposed on the second transmission seat.

[0194] In this embodiment, a pair of grippers 4002 are respectively disposed at both ends of the first transmission seat, and the first alignment seat 4009 is disposed in the middle of the first transmission seat. Both the grippers 4002 and the first alignment seat 4009 are located on the side of the first transmission seat facing the second alignment seat 40010. The drive assembly drives the first alignment seat 4009 and the grippers 4002 to rotate synchronously through the first transmission seat. The rotation is stable and the structure is simple.

[0195] In the optional technical solution of this embodiment, a first one-way telescopic cylinder is also included. The first one-way telescopic cylinder is disposed on the second transmission seat, and the telescopic end of the first one-way telescopic cylinder is connected to the second alignment seat 40010.

[0196] In this embodiment, the drive assembly drives the second alignment seat 40010 and the first one-way telescopic cylinder to rotate synchronously via the second transmission seat, resulting in stable rotation and a simple structure. Simultaneously, the second alignment seat 40010 can move closer to or further away from the first alignment seat 4009 via the first one-way telescopic cylinder. That is, while the first alignment seat 4009 remains stationary, the movement of the second alignment seat 40010 allows the first alignment seat 4009 and the second alignment seat 40010 to move closer or further apart, resulting in a simple structure, greater overall stability, and cost savings.

[0197] In the optional technical solution of this embodiment, a straightening frame 4001 is also included. The straightening frame 4001 has a first beam and a second beam opposite to each other. The driving component is disposed on the straightening frame 4001, and the first straightening seat 4009 is located at the first beam and the second straightening seat 40010 is located at the second beam. Mounting frames are provided at both ends of the first beam and both ends of the second beam. The bearing component is disposed on the mounting frame and located inside the mounting frame.

[0198] In this embodiment, the first pulley connected to the first transmission seat is mounted on the first beam via a seat body, and the second pulley connected to the second transmission seat is mounted on the first beam via a seat body. Both the seat body and the mounting frame are located below the first and second beams. The drive motor 4007 is mounted at the bottom of the straightening frame 4001, and the transmission shaft 4006 is mounted at the bottom of the straightening frame 4001 via a shaft seat. The overall structure is simple and occupies little space. The straightening frame 4001 can protect the wooden guardrail 44 from contact with the outside and prevent damage.

[0199] In the optional technical solution of this embodiment, the driving component includes a pair of grippers 4002, a pair of driven wheels 4003, a pair of driving wheels 4004, a first transmission belt 4005, a transmission shaft 4006, and a drive motor 4007. The pair of driven wheels 4003 are respectively disposed at the first beam and the second beam, and are respectively connected to the first transmission seat and the second transmission seat, and are used to drive the first transmission seat and the second transmission seat to rotate. The drive motor 4007 is disposed at the bottom of the straightening frame 4001 and is connected to the transmission shaft 4006. The pair of driving wheels 4004 are spaced apart on the transmission shaft 4006 and correspond one-to-one with the pair of driven wheels 4003. The driving wheels 4004 and the corresponding driven wheels 4003 are connected by the first transmission belt 4005. The overall structure is simple and the driving effect is stable.

[0200] In the optional technical solution of this embodiment, the bearing component includes a second one-way telescopic cylinder and a bearing seat 4008; the bearing seat 4008 is connected to the telescopic end of the second one-way telescopic cylinder and is used to support the corner of the wooden guard 44.

[0201] In this embodiment, the support seats 4008 that engage with the two corners of the first side of the wooden guard 44 can extend or retract towards the second side under the drive of the second one-way telescopic cylinder. The support seats 4008 that engage with the two corners of the second side of the wooden guard 44 can extend or retract towards the first side under the drive of the second one-way telescopic cylinder. When the wooden guard 44 needs to be straightened, the four support seats 4008 extend so that the four corners of the wooden guard 44 can be placed on the four support seats 4008. After the wooden guard 44 is straightened and needs to be removed, when the robotic arm grasps the wooden guard 44, the four support seats 4008 retract. At this time, the support seats 4008 detach from the wooden guard 44, avoiding the flanges on the two sides outside the first and second sides of the wooden guard 44 from getting stuck on the support seats 4008 when the robotic arm moves the wooden guard 44, which would affect the movement of the wooden guard 44 and prevent damage to the wooden guard 44.

[0202] In the optional technical solution of this embodiment, the support device 43 includes a support arm 4301, a fixed seat 4302, a gear 4303, a rack 4304, and a first cylinder 4305; the fixed seat 4302 is connected to the Y-axis roller conveyor line 38, one end of the gear 4303 is rotatably connected to the fixed seat 4302, and the other end is fixedly connected to the support arm 4301, and the gear 4303 meshes with the rack 4304; the output end of the first cylinder 4305 is connected to the rack 4304, and the rack 4304 drives the gear 4303 to reciprocate, thereby driving the support arm 4301 to reciprocate between a first position and a second position, and when the support arm 4301 is in the first position, it is used to support the wooden guardrail 44, and when the support arm 4301 is in the second position, it is used to avoid the conveying of the photovoltaic module 34.

[0203] In this embodiment, a shaft is provided on the gear 4303, and the lower end of the shaft is connected to the fixed base 4302 through the bearing 43017, while the upper end is fixedly connected to the support arm 4301. The rack 4304 is arranged laterally and meshes with the gear 4303. The output end of the first cylinder 4305 drives the rack 4304 to reciprocate in the horizontal plane, thereby driving the gear 4303 to rotate, which in turn causes the gear 4303 to drive the support arm 4301 to rotate in the horizontal plane. The support arm 4301 can enter the first position inside the Y-direction roller conveyor line 38 and the second position outside the Y-direction roller conveyor line 38 through transmission. The structure is simple, and the drive is stable and convenient.

[0204] In use, the support arm 4301 of the support device 43 is in the second position. The Y-axis roller conveyor 38 transports the photovoltaic module 34 after it is boxed to the support device 43. Since the support arm 4301 is in the second position, it can avoid collision with the cardboard box outside the photovoltaic module 34. After the wooden guard 44 is installed on the outside of the cardboard box, the support arm 4301 rotates from the second position to the first position under the drive of the first cylinder 4305 and supports the wooden guard 44 to prevent it from moving. The structure is simple, the degree of automation is high, it saves manpower and improves packaging efficiency.

[0205] Specifically, the support device 43 also includes a connecting seat 4306, a transmission seat 4307, a first slide rail 4308, and a second slider 4309. The first slide rail 4308 and the first cylinder 4305 are both connected to the first fixed seat 4302, and the first cylinder 4305 and the gear 4303 are located on opposite sides of the first slide rail 4308 along the sliding direction. The second slider 4309 is slidably connected to the first slide rail 4308, the connecting seat 4306 is connected to the second slider 4309, and the rack 4304 is connected to the connecting seat 4306. The extension and retraction direction of the first cylinder 4305 is the same as the sliding direction of the second slider 4309, and the output end of the first cylinder 4305 is connected to the connecting seat 4306 via the transmission seat 4307. First limiting blocks 43010 are provided at both ends of the first slide rail 4308, and the first limiting blocks 43010 are used to restrict the second slider 4309 from disengaging from the first slide rail 4308 along the sliding direction. Preferably, the first limiting block 43010 is made of a flexible material, which provides good buffering and limiting effect. The flexible material can be rubber, silicone, or plastic, etc. A pair of mounting brackets 43011 are also provided on the fixed base 4302, and along the sliding direction of the slider, the pair of mounting brackets 43011 are located at opposite ends of the connecting base 4306; each mounting bracket 43011 is provided with a buffer 43012 corresponding to the connecting base 4306. A handrail 43013 is provided on the support arm 4301. The handrail 43013 is L-shaped and has two sections; one section of the handrail 43013 supports the vertical edge of the wooden guardrail 44, and the other section supports the horizontal edge of the wooden guardrail 44. Since the wooden guardrail 44 has a square frame, the handrail 43013 can simultaneously support both the horizontal and vertical edges of the wooden guardrail 44, improving the stability of the wooden guardrail 44. A flexible pad 43014 is provided on the handrail 43013, which supports the wooden guardrail 44 through the flexible pad 43014. To prevent damage to the wooden guardrail 44, preferably, the flexible pad 43014 is a rubber pad, silicone pad, or plastic pad, etc., as long as it meets the requirements. The first position is parallel to the conveying direction of the Y-axis roller conveyor line 38, and the second position is perpendicular to the conveying direction of the Y-axis roller conveyor line 38. That is, the support arm 4301 can rotate 90° in the horizontal plane, which is convenient for control and provides good support and avoidance effects.

[0206] In this embodiment, the fixing seat 4302 can be set on the outside of the Y-direction roller conveyor line 38 or on the Y-direction roller conveyor line 38.

[0207] Preferably, the fixed base 4302 includes a bearing portion 43015 and a connecting portion 43016 located below the bearing portion 43015; the support arm 4301 is rotatably connected to the bearing portion 43015, the connecting portion 43016 is connected to the Y-direction roller conveyor line 38, and the bearing portion 43015 and the Y-direction roller conveyor line 38 are spaced apart in the height direction, so that the bearing portion 43015 and the Y-direction roller conveyor line 38 are spaced apart, which can better support the wooden guardrail 44.

[0208] In the optional technical solution of this embodiment, the robotic arm 41 includes a first base 4101, a first six-axis robotic arm 4102, a fixed frame 4103, and a pair of movable clamping arms 4104 that can move closer to or further away from each other; the first base 4101 is slidably connected to the first Y-axis ground rail 39, the first six-axis robotic arm 4102 is disposed on the first base 4101 and its end is connected to the back side of the fixed frame 4103, and the pair of movable clamping arms 4104 are disposed on the front side of the fixed frame 4103 and are used to clamp the wooden guardrail 44.

[0209] In this embodiment, during use, the first six-axis robotic arm 4102 drives the fixed frame 4103 to move to the wooden baffle buffer device 42. A pair of movable grippers 4104 approach each other and grip the wooden baffle 44. Then, the first six-axis robotic arm 4102 drives the fixed frame 4103 to move to the photovoltaic module 34 on the Y-axis roller conveyor line 38, adding the wooden baffle 44 to the outside of the carton, thus achieving automatic addition of the wooden baffle 44. The structure is simple, saves manpower, and improves packaging efficiency. At the same time, the first six-axis robotic arm 4102 is highly flexible, making it convenient and stable to drive the fixed frame 4103, improving the reliability of transporting the wooden baffle 44. The approach or movement of the pair of movable grippers 4104 is achieved by a drive mechanism, and there are many existing technologies for drive mechanisms that can drive the pair of movable grippers 4104, which will not be described in detail here.

[0210] In the optional technical solution of this embodiment, the corner protector 48 installation mechanism includes a corner protector buffer device 45, a corner protector gripper 46, and a drive device 47 for driving the corner protector gripper 46 to reciprocate between the corner protector buffer device 45 and the Y-axis roller conveyor line 38. The corner protector gripper 46 includes a claw arm 4601, a claw hand 4602, and a roller 4603. The claw arm 4601 is connected to the drive device 47, and the claw hand 4602 is hinged to the end of the claw arm 4601, with a torsion spring 4604 at the hinge. The claw hand 4602 is L-shaped and has a first segment and a second segment connected together. The length of the first segment is greater than the length of the second segment. A first suction cup 4605 is provided on both the first segment and the second segment, and a roller 4603 is provided at the end of the first segment away from the second segment. The structure is simple, and the corner protector 48 is easy to install.

[0211] In the optional technical solution of this embodiment, a pair of corner guard grippers 46 are provided, and the driving device 47 includes a first X-direction driving component, a second X-direction driving component, and a pair of Y-direction driving components corresponding one-to-one with the pair of corner guard grippers 46; the Y-direction driving component is tractively connected to the corner guard gripper 46 and is used to drive the corner guard gripper 46 to reciprocate along the Y direction; the first X-direction driving component is tractively connected to the pair of corner guard grippers 46, the pair of Y-direction driving components, and the second X-direction driving component, and is used to drive the pair of corner guard grippers 46, the pair of Y-direction driving components, and the second X-direction driving component to extend into or exit the Y-direction roller conveyor line 38 along the X direction; the second X-direction driving component is tractively connected to one corner guard gripper 46 and one corresponding Y-direction driving component, and is used to drive the pair of corner guard grippers 46 and the pair of Y-direction driving components to move closer or further away from each other along the X direction.

[0212] In this embodiment, two corner protector mounting mechanisms are provided, and they are respectively used to cooperate with the side of the carton along the Y-direction roller conveyor line 38. The claw arm 4601 is made of aluminum alloy profile, and a claw hand 4602 is hinged to its end. The first X-direction drive assembly and the second X-direction drive assembly cooperate to drive the pair of claw arms 4601 to a position opposite to the corner protector buffer device 45. The Y-direction drive 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 drive assembly drives the claw arm 4601 to retract, and the first X-direction drive assembly and the second X-direction drive assembly cooperate to drive the pair of claw arms 4601 to move. The claw arm 4601 extends to the side of the carton, aligning the corner protectors 48 with the side corners of the carton. The Y-axis drive assembly extends the claw arm 4601. Since the roller 4603 is located at the end of the longer first section of the claw 4602, it first contacts the carton. As the claw arm 4601 continues to extend, the roller 4603 rolls along the side of the carton while the claw 4602 rotates, attaching the corner protectors 48 to the side corners of the carton. This ensures the corner protectors 48 are accurately and stably fitted to the carton, improving packaging efficiency and effectiveness. When the claw arm 4601 retracts, the claw 4602 resets under the action of the torsion spring 4604. The structure is simple, the reset motion is effective, and the stability is high when the corner protectors 48 are attached. The roller 4603 ensures stable rotation of the claw 4602, preventing jamming.

[0213] Furthermore, the end of the claw arm 4601 has a pair of limiting end plates 4606, the claw hand 4602 is hinged to the pair of limiting end plates 4606, the first proximity switch 4608 is mounted on one of the limiting end plates 4606, and the limiting end plate 4606 has a limiting plane located on the side near the roller 4603. The claw hand 4602 has a limiting plate 4607, the limiting plate 4607 facing the claw arm 4601 and abutting against the end of the claw arm 4601 for limitation, and the first proximity switch 4608 is correspondingly engaged with a first suction cup 4605. In this design, to prevent over-twisting during the rotation of the gripper 4602, when the rotation is complete, the back of the gripping surface of the gripper 4602 near the roller 4603 abuts against the limiting plane of the limiting end plate 4606, so that this gripping surface is exactly parallel to the side of the carton. At this time, the other gripping surface is also parallel to the adjacent surface of the carton, allowing the corner protector 48 to be installed at the side corner of the carton. When the gripper 4602 resets, to prevent over-reset, during the reset rotation via the torsion spring 4604, the limiting plate 4607 on the gripper 4602 moves toward the end of the gripper arm 4601 until it abuts, achieving both limiting and reset positions. The structure is simple, and the reset effect is good and stable. Furthermore, when the limiting plate 4607 on the gripper 4602 abuts against the end of the gripper arm 4601, the first proximity switch 4608 is directly opposite a suction cup. At this time, the first proximity switch 4608 receives a signal, indicating that the reset is complete, in preparation for the next gripping of the corner protector 48.

[0214] In this embodiment, the first X-axis drive assembly includes a first X-axis seat 4701, a first X-axis slide rail 4702, and a first servo motor 4703; the second X-axis drive assembly includes a motion frame 4704, a second X-axis seat 4705, a second X-axis slide rail 4706, and a second servo motor 4707; the Y-axis drive assembly includes a second cylinder 4708 and a connecting rod. The first X-axis seat 4701 is fixedly mounted, the first X-axis slide rail 4702 and the first servo motor 4703 are both mounted on the first X-axis seat 4701, and the second servo motor 4707 is mounted on the motion frame 4704. The X-axis slide rail 4706 is mounted on the second X-axis seat 4705. The motion frame 4704 is located between the first X-axis seat 4701 and the second X-axis seat 4705. The motion frame 4704 is slidably connected to both the first X-axis slide rail 4702 and the second X-axis slide rail 4706. One of the pair of Y-axis drive components and one of the pair of corner guards 46 are fixed on the motion frame 4704. The other drive component and the corner guard 46 are fixed on the second X-axis seat 4705. The second cylinder 4708 of the Y-axis drive component is connected to the claw arm 4601 of the corner guard 46 via a connecting rod. The first servo motor 4703 drives the motion frame 4704 to slide on the first X-axis seat 4701 via pulleys and a synchronous belt. This causes the motion frame 4704 to drive the second X-axis seat 4705 to move synchronously in the X-direction. Consequently, a pair of Y-axis drive components and the second X-axis drive components extend into or exit the Y-axis roller conveyor line 38 along the X-direction. The second servo motor 4707 drives the second X-axis seat 4705 to slide on the motion frame 4704 via pulleys and a synchronous belt. This causes the second X-axis seat 4705 to drive a Y-axis drive component and a corner guard 46 to move along the X-direction. Consequently, a pair of corner guards 46 and a pair of Y-axis drive components move closer or further apart along the X-direction. The drive device 47 has a simple structure and provides stable drive.

[0215] In the optional technical solution of this embodiment, the Y-direction roller conveyor 38 has a translation section 49, which includes a frame 4901, an X-direction ground rail 4902, a section of Y-direction roller conveyor 4903, and a third X-direction drive assembly. The section of Y-direction roller conveyor 4903 is disposed on the frame 4901, the frame 4901 is disposed on the X-direction ground rail 4902, and the third X-direction drive assembly is used to drive the frame 4901 to reciprocate along the X-direction on the X-direction ground rail 4902. The second belt-binding mechanism includes an X-direction belt-binding machine 50 and a Y-direction belt-binding machine 51. The X-direction belt-binding machine 50 is mounted on the Y-direction roller conveyor 38 and is located upstream of the section of Y-direction roller conveyor 4903. The Y-direction belt-binding machine 51 is mounted on the X-direction ground rail 4902.

[0216] The X-axis ground rail 4902 includes a rectangular frame 4904 and legs 4905; the rectangular frame 4904 has opposing X-axis beams, and multiple legs 4905 are spaced apart on each X-axis beam; two Y-axis shafts 4906 are provided on the frame 4901, and the two Y-axis shafts 4906 are spaced apart along the X-axis, and rollers 4907 are provided at both ends of each Y-axis shaft 4906, and the rollers 4907 at both ends of the Y-axis shaft 4906 are respectively rolledly connected to the upper surface of the opposing X-axis beam; a third X-axis drive assembly is used to drive the rollers 4907 to reciprocate along the X-axis on the upper surface of the X-axis beam.

[0217] In this embodiment, the two ends of the Y-axis 4906 are connected to the bottom of the frame 4901 through bearing seats, and the two rollers 4907 on the Y-axis 4906 are located between the two bearing seats. The drive assembly drives the Y-axis 4906 to rotate, causing the rollers 4907 to roll on the X-axis beam. The structure is simple and the frame 4901 is stable in translation.

[0218] In an optional technical solution of this embodiment, the frame 4901 is further provided with at least one pair of auxiliary wheels 4908, and the two auxiliary wheels 4908 in each pair are respectively rolledly connected to the side of the opposite X-direction beam. The provision of auxiliary wheels 4908 makes the frame 4901 more stable during translation and avoids tilting.

[0219] In this embodiment, each pair of auxiliary wheels 4908 can be located on the outside of the opposite X-direction beam, or they can be located between the opposite X-direction beams.

[0220] In the optional technical solution of this embodiment, the side of the X-direction beam is provided with a guide limiting rib 4909 extending along the X-direction, and the auxiliary wheel 4908 is located below the guide limiting rib 4909.

[0221] In this embodiment, the wheel surface of the auxiliary wheel 4908 abuts against the side of the X-direction beam, and the upper side of the auxiliary wheel 4908 is located below the guide rib. The guide limiting rib 4909 can restrict the auxiliary wheel 4908 from detaching from the X-direction beam from above, thus ensuring the stability of the frame 4901 movement.

[0222] In the optional technical solution of this embodiment, two second proximity switches 49010 are arranged at intervals along the X direction on the side of the X-direction beam, and a detection plate 49011 that cooperates with the second proximity switches 49010 is arranged on the frame 4901.

[0223] In this embodiment, when the frame 4901 moves out to the preset position, the detection plate 49011 blocks one of the second proximity switches 49010, causing the frame 4901 to stop at the preset position. When the frame 4901 moves back, the detection plate 49011 blocks the other second proximity switch 49010, ensuring that the frame 4901 can return to its original position accurately, thereby enabling a section of Y-axis roller conveyor line 4903 to form a continuous conveyor line with the remaining sections of Y-axis roller conveyor line 38.

[0224] In the optional technical solution of this embodiment, two contact roller sensors 49016 that cooperate with the bottom of the frame 4901 are also arranged at intervals along the X-direction on the side of the X-direction beam, and the two second proximity switches 49010 are both located between the two contact roller sensors 49016. This further ensures the accuracy of the moving position of the frame 4901 and avoids excessive movement of the frame 4901 when the second proximity switches 49010 malfunction or the detection plate 49011 is inaccurate.

[0225] In the optional technical solution of this embodiment, the third X-axis drive component includes a third servo motor 49012, a transmission chain, and a pair of transmission gears 49013; the third servo motor 49012 is mounted on the frame 4901, and the pair of transmission gears 49013 are respectively mounted on the output end of the third servo motor 49012 and the Y-axis 4906, and the pair of transmission gears 49013 are connected by the transmission chain.

The two transmission gears 49013 are connected by a transmission chain. The drive assembly has a simple structure and stable drive.

[0227] In the optional technical solution of this embodiment, a cable carrier 49014 for internal cables is also included. The cable carrier 49014 is located outside the X-direction ground rail 4902, with one end connected to the X-direction ground rail 4902 and the other end connected to the rack 4901. The cable carrier 49014 protects the cables from wear, and one end of the cable carrier 49014 can move with the rack 4901 to prevent the cables inside the cable carrier 49014 from being stretched.

[0228] In the optional technical solution of this embodiment, a support frame 49015 is also included. The support frame 49015 is connected to the outside of the X-direction ground rail 4902, and the cable chain 49014 is disposed on the support frame 49015, with one end connected to the support frame 49015.

[0230] The carton gripper 52 and the carton unfolding handle 53 are located on both sides of the Y-axis roller conveyor line 38. The first suction cup frame 5203 uses the second suction cup 5206 to adhere to one side of the carton from the outside, while simultaneously using the carton unfolding handle 53 to adhere to the opposite side of the carton and unfold it. Then, the second suction cup frame 5204 flips relative to the first suction cup frame 5203 and uses the second suction cup 5206 to adhere to one outer wall surface of the carton. That is, the first suction cup frame 5203 and the second suction cup frame 5204 respectively adhere to the adjacent side of the carton using the second suction cup 5206. On both sides, the third suction cup frame 5205 slides relative to the first suction cup frame 5203, allowing the second suction cup frame 5204 to adhere to one outer wall of the carton via the second suction cup 5206.
