[0017] In the following description, only certain exemplary embodiments are briefly described. As those skilled in the art will recognize, the described embodiments can be modified in various ways without departing from the spirit or scope of this application. Therefore, the drawings and description are considered to be exemplary in nature and not restrictive.

[0018] like Figure 1 , Figure 2 , Figure 4 As shown, this application embodiment provides a box unpacking system for battery cell packaging boxes, including a machine body 1, and a box rejection device 2 and a waste rejection device 3 disposed on the machine body 1. The box rejection device 2 includes a box conveyor line 21, a cutting device 22, a box rejection device 23, and a waste conveyor line 24, with the waste conveyor line 24 located below the discharge end of the box conveyor line 21. The cutting device 22 includes a cutting moving mechanism 221 and a cutting mechanism 222, which are connected to the cutting moving mechanism 221. The cutting moving mechanism 221 drives the cutting mechanism 222 to move above the box conveyor line 21. The box rejection device 23 is located at the discharge end of the box conveyor line 21 and includes a box flipping mechanism 231 and a gripping moving mechanism 232. The box flipping mechanism 231 can flip the box 4. The gripping moving mechanism 232 is equipped with a gripping suction cup 2321. The waste removal device 3 is located outside the discharge end of the box conveyor line 21. The waste removal device 3 includes a synchronous conveying device 31 and a material removal device 32. Figure 10 As shown, the synchronous conveying device 31 is equipped with conveying grippers 311. For example... Figure 7 , Figure 8 As shown, the material rejection device 32 includes a material rejection mechanism 321 and a material rejection moving mechanism 322. The material rejection mechanism 321 includes a material rejection suction cup 3211, and the material rejection moving mechanism 322 is connected to the material rejection suction cup 3211.

[0019] The unpacking system for the battery cell packaging box of this application includes a box rejection device 2 and a waste rejection device 3. The battery cell assembly 5 packaged inside the packaging box 4 is first conveyed to the box conveyor line 21 and driven forward by the box conveyor line 21, at which time the opening of the box 4 faces upward. The box 4 is first conveyed to the cutting device 22, and the cutting moving mechanism 221 drives the cutting mechanism 221 to move, cutting open the plastic sealing film on the outside of the box 4 and the plastic bag packaging the battery cell assembly 5. Then, the box 4 continues to be conveyed forward to the box rejection device 23, and the gripping suction cup 2321 picks up and removes the cut plastic sealing film and plastic bag. Then, the box flipping mechanism 231 drives the box 4 to flip, so that the opening of the box 4 faces downward. Then, the gripping suction cup 2321 picks up and removes the remaining plastic sealing film, and also picks up and removes the box 4. After the box body 4 is removed, the battery cell assembly 5 is then transferred to the waste removal equipment 3 via the synchronous conveying device 31. The hollow board, pearl cotton, and sulfur-free paper are then removed by the material removal suction cup 3211. The battery cell packaging box unpacking system of this embodiment can automatically remove the packaging box and packaging waste without manual operation, thus improving work efficiency and saving labor costs.

[0020] The unpacking system for the battery cell packaging box of this application can be used in conjunction with the patent "Unpacking System for Battery Cell Packaging Box" applied for by the applicant. After the box body 4 is taken out from the packaging box, the unpacking system for the battery cell packaging box transports the box body 4 to the unpacking system for the battery cell packaging box via a conveyor belt, and then performs the unpacking operation to complete the operation of taking the battery cells out of the packaging box and the box body 4 of the packaging box.

[0021] Specifically, such as Figure 2 As shown, in order to transport the box 4 from the previous process to the box conveyor line 21, the box rejection device 23 also includes a receiving and flipping mechanism 233. The receiving and flipping mechanism 233 serves as a connecting process between the unpacking system of the battery cell packaging box and the unpacking system of the battery cell packaging box, enabling the transport of the box 4 between the two systems.

[0022] like Figure 4 , Figure 5 As shown, to achieve the conveying of the box 4, the receiving and flipping mechanism 233 includes a receiving lifting assembly 2331, a receiving and flipping assembly 2332, a receiving gripper 2333, and a pushing assembly 2334. The receiving and flipping assembly 2332 is slidably connected to the receiving lifting assembly 2331, and the receiving gripper 2333 is connected to the receiving and flipping assembly 2332. The receiving gripper 2333 is located at the feeding end of the box conveyor line 21, and the pushing assembly 2334 is located behind the feeding end of the box conveyor line 21.

[0023] To facilitate the transfer of the receiving gripper 2333 between the unpacking system and the box unpacking system, the receiving flipping mechanism 233 may further include a receiving translation component. A receiving lifting component 2331 is slidably connected to the receiving translation component. The receiving translation component drives the receiving lifting component 2331 to move horizontally, and the receiving lifting component 2331 drives the receiving flipping component 2332 to rise and fall. Preferably, both the receiving lifting component 2331 and the receiving translation component are existing commercially available linear modules, and horizontal movement and rising / falling are achieved through the linear modules.

[0024] like Figure 5 As shown, the receiving and flipping assembly 2332 includes a receiving and flipping motor 23321 and a receiving fixing plate 23322. The receiving fixing plate 23322 is slidably connected to the receiving and lifting assembly 2331 via a slider, and the receiving and flipping motor 23321 is fixed on the receiving fixing plate 23322. The output end of the receiving and flipping motor 23321 is connected to the receiving gripper 2333, which is controlled to open and close by a finger cylinder. During receiving, the receiving and translating assembly can move the receiving gripper 2333 to the discharge end of the unpacking system, and the receiving gripper 2333 can grab the box 4. Then, the translating assembly can move the gripper to the feed end of the box conveyor line 21.

[0025] The feeding assembly 2334 includes a feeding cylinder 23341 and a feeding clamp 23342. The output end of the feeding cylinder 23341 is connected to the feeding clamp 23342. The feeding cylinder 23341 drives the feeding clamp 23342 to move towards or away from the feeding end of the box conveyor line 21.

[0026] like Figure 4 As shown, a material support fixing seat 2335 is also provided between the pusher cylinder 23341 and the feeding end of the box conveyor line 21. A material support roller shaft 2336 is installed on the top of the material support fixing seat 2335. The material support roller shaft 2336 and the material support fixing seat 2335 are slidably connected by bearings.

[0027] After the receiving gripper 2333 picks up the box body 4, the receiving translation component and the receiving lifting component 2331 move the box body 4 to above the material support roller shaft 2336 and the box body conveyor line 21. The receiving flipping motor 23321 then flips the box body 4 from a vertical position to a horizontal position, with the opening of the box body 4 facing downwards. When the box body 4 approaches the height of the material support roller shaft 2336 and the box body conveyor line 21, the receiving gripper 2333 releases the box body 4, and the box body 4 falls onto the material support roller shaft 2336 and is positioned in the middle of the pusher clamp 23342. Then, the pusher cylinder 23341 moves the pusher clamp 23342 towards the box body conveyor line 21, pushing the box body 4 to the feed end of the box body conveyor line 21, where it is then conveyed forward by the box body conveyor line 21.

[0028] The box conveyor line 21 is an existing material conveyor line, which is realized by two spaced conveyor belts, and the conveyor belts are driven by a motor to move.

[0029] As the box conveyor 21 moves the box 4 forward, it is first conveyed to the cutting device 22 for cutting. Before cutting, the box 4 needs to be aligned; therefore, as... Figure 2 As shown, the box rejection device 2 also includes a box straightening mechanism 25 for straightening the box 4. The box straightening mechanism 25 is connected to the box conveyor line 21 and is located below the cutting moving mechanism 221.

[0030] like Figure 4 As shown, the box alignment mechanism 25 includes two box side alignment components 251 and a box end alignment component 252. The two box side alignment components 251 are located on the left and right sides of the box conveyor line 21, respectively, while the two box end alignment components 252 are located between the two conveyor belts. The two box side alignment components 251 are used to align the left and right sides of the box 4, and the two box end alignment components 252 are used to align the front and rear ends of the box 4.

[0031] The side alignment assembly 251 includes a side alignment cylinder 2511 and a side alignment plate 2512. The side alignment cylinder 2511 is fixed on the box conveyor line 21, and the output end of the side alignment cylinder 2511 is connected to the side alignment plate 2512. The end alignment assembly 252 includes an alignment lifting cylinder 2521, an end alignment cylinder 2522, and an end alignment plate 2523. The alignment lifting cylinder 2521 is fixed on the machine body 1, and the output end of the alignment lifting cylinder 2521 is connected to the end alignment cylinder 2522. The output end of the end alignment cylinder 2522 is connected to the end alignment plate 2523.

[0032] After the box conveyor line 21 transports the box 4 to the alignment position, the side alignment cylinder 2511 drives the side alignment plate 2512 to align the left and right sides of the box 4. The alignment lifting cylinder 2521 drives the end alignment cylinder 2522 to rise, and then the end alignment cylinder 2522 drives the end alignment plate 2523 to move, moving the front and rear ends of the box 4. After the box 4 is aligned and it needs to continue being transported, the side alignment component 251 and the end alignment component 252 return to their original positions. The alignment lifting cylinder 2521 allows the end alignment component to align the box 4 without affecting its transport on the box conveyor line 21.

[0033] After the box 4 is conveyed, the cutting device 22 then cuts the sealed plastic bag and the plastic bag packaging the battery cell assembly 5. The cutting moving mechanism 221 can be an existing XY linear module. The cutting device 22 is slidably connected to the XY axis linear module through a slider, so that the XY axis linear module can drive the cutting mechanism 222 to move in the X-axis and Y-axis directions.

[0034] The cutting mechanism 222 of this application is a commercially available carbon dioxide laser cutting head. This cutting head works in conjunction with the laser cutting system on the laser cutting machine to achieve cutting. The collaborative operation of the cutting head with the laser cutting system on the laser cutting machine is also prior art, and this application does not involve any improvement to its structure or control method. In one embodiment, the cutting mechanism 222 can also be a small-scale cutting mechanism 222 machine.

[0035] like Figure 4 As shown, waste gas is generated during laser cutting. To facilitate the discharge of this waste gas, the cutting device 22 also includes a blower 223. The blower 223 can also be slidably connected to the XY axis linear module via a slider. The air outlet of the blower 223 can be connected to the outside via a pipe, allowing the waste gas generated during the cutting process to be discharged through the blower 223.

[0036] like Figure 15 As shown in the figure, the dotted line part is a path diagram of one type of cutting. When cutting, the plastic film and plastic bag can be cut together.

[0037] After cutting, the box 4 continues to be conveyed forward by the box conveyor line 21 and is transported to the discharge end of the box conveyor line 21. As shown in the figure, the box rejection device 23 also includes a rejection platform 234, on which the box conveyor line 21 can directly transport the box 4. The rejection platform 234 has a gap in the middle.

[0038] After the box 4 is conveyed to the rejection platform 234, the gripping and moving mechanism 232 first removes the plastic seal film and plastic bag. Specifically, the gripping and moving mechanism 232 also includes a gripping and moving component 2321 and a gripping and lifting component 2322, which are slidably connected to the gripping and moving component 2321 via a slider. Preferably, the gripping and moving component 2321 is an existing linear module, and the gripping and lifting component 2322 can be a cylinder or an existing linear module. The output end of the gripping and lifting component 2322 is connected to the gripping suction cup 2321, which can pick up the plastic seal film, plastic bag, and box 4 through vacuum adsorption.

[0039] Since the opening of the box 4 is facing upwards when it is conveyed to the rejection platform 234, after the gripping suction cup 2321 picks up and removes the cut plastic film and plastic bag, the box 4 needs to be flipped over to be rejected. Figure 6 As shown, to achieve the flipping of the box 4, the box flipping mechanism 231 includes a box flipping motor 2311, a box flipping gripper 2312, and a box moving assembly 2313. The output end of the box flipping motor 2311 is connected to the box flipping gripper 2312, which is controlled by a cylinder to open and close. The box flipping motor 2311 is connected to the box moving assembly 2313 via a slider, and the box moving assembly 2313 drives the box flipping gripper 2312 to move towards or away from the rejection platform 234. The rejection platform 234 has a gap in the middle, and the box flipping gripper 2312 can enter the gap to grip the box 4.

[0040] After the gripping suction cup 2321 removes the plastic film and plastic bag, the box body 4 is then gripped by the flipping claws, which pick up the box body 4 and the battery cell assembly 5 inside. Next, the box body flipping motor 2311 drives the box body flipping claws 2312 to rotate 180 degrees, so that the opening of the box body 4 faces downwards. Then, the gripping suction cup 2321 picks up the remaining plastic film and box body 4, removing them completely.

[0041] In one embodiment, to prevent the rejection platform 234 from interfering with the flipping of the box 4, the box flipping mechanism 231 may further include a box flipping lifting assembly, and the box moving assembly 2313 is connected to the box flipping lifting assembly via a slider. The box moving assembly 2313 and the box flipping lifting assembly can be existing linear modules. The box flipping lifting assembly drives the box flipping gripper 2312 to rise and fall. After the box flipping gripper 2312 grips the box 4, it can drive the box 4 to rise before flipping, thus preventing the rejection platform 234 from affecting the flipping of the box 4.

[0042] After the suction cup 2321 adsorbs the plastic film, plastic bag, and box 4, it conveys them above the waste conveyor line 24. Then, the plastic film, plastic bag, and box 4 are placed on the waste conveyor line 24 and conveyed out. The waste conveyor line 24 can be a commonly used conveyor belt on the market, which can realize the material conveying.

[0043] After the box body 4 is removed, the flipping gripper of the box body 4 drives the battery cell assembly 5 to rotate 90 degrees, making it vertical, waiting for the waste removal equipment 3 to remove the packaging waste (hollow board, pearl cotton and sulfur-free paper).

[0044] like Figure 7As shown, the battery cell assembly 5, after being removed from the box 4, is transported to the waste removal device 3 by the transport grippers 311 of the synchronous transport device 31. To facilitate the transport of the battery cell assembly 5, the synchronous transport device 31 also includes a synchronous transport moving mechanism 312 and a transport flipping mechanism 313. There are five transport grippers 311, all of which are connected to the synchronous transport moving mechanism 312. The transport flipping mechanism 313 is connected to the synchronous transport moving mechanism 312, and is connected to two of the transport grippers 311, causing the transport grippers 311 to flip.

[0045] Specifically, such as Figure 10 As shown, the synchronous transport and movement mechanism 312 includes a synchronous lateral movement component 3121 and a synchronous lifting component 3122. The synchronous lifting component 3122 is connected to the synchronous lateral movement component 3121 via a slider. Both the synchronous lateral movement component 3121 and the synchronous lifting component 3122 can be existing linear modules, which realize lateral movement and lifting.

[0046] The synchronous lifting assembly 3122 is connected to the transport connecting plate 3123 via a slider, wherein three transport grippers 311 are fixed on the transport connecting plate 3123 and are spaced apart from each other.

[0047] like Figure 11 As shown, the handling and flipping mechanism 313 includes a handling and flipping fixed base 3131, a handling and flipping motor 3132, and a flipping shaft 3133. The handling and flipping fixed base 3131 is fixedly connected to the handling connecting plate 3123. The handling and flipping motor 3132 is fixed on the handling and flipping fixed base 3131. The two ends of the flipping shaft 3133 are rotatably connected to the handling and flipping fixed base 3131 through bearings, and the output end of the handling and flipping motor 3132 is connected to the flipping shaft 3133. Two of the handling grippers 311 are connected to the flipping shaft 3133 through connecting seats. After the handling and flipping motor 3132 is started, it can drive the flipping shaft 3133 to rotate, and the flipping shaft 3133 drives the handling grippers 311 to rotate, thereby causing the battery cell assembly 5 held by the handling grippers 311 to flip. The five handling grippers 311 of this application are all controlled by finger cylinders to open and close, thereby realizing the handling of the battery cell assembly 5.

[0048] In one embodiment, such as Figure 2 , Figure 7As shown, the waste rejection equipment 3 also includes a bag rejection device 33 and a battery cell alignment device 34, which are arranged sequentially. Since the synchronous lateral movement component 3121 can simultaneously drive the five transport grippers 311 to move, it can simultaneously drive the four battery cell components 5 to achieve synchronous transport. Specifically, the first transport gripper 311 can move above the rejection platform 234 to move the battery cell assembly 5 gripped by the box-flipping gripper 2312 to the bagging rejection device 33. The second transport gripper 311 moves to the bagging rejection device 33 and moves the battery cell assembly 5 on the bagging rejection device 33 to the material rejection device 32. The third transport gripper 311 moves to the material rejection device 32 and moves the battery cell assembly 5 on the material rejection device 32 to the battery cell alignment device 34. The fourth and fifth transport grippers 311 move to the battery cell alignment device 34 and together move the aligned battery cell assembly 5 to the next device for the next operation. By setting up the synchronous transport device 31, this application can simultaneously realize the synchronous transport and movement of multiple battery cell assemblies 5 between multiple processes, greatly improving work efficiency.

[0049] In one embodiment, such as Figure 7 As shown, the bagging rejection device 33 includes a bagging rejection base 331, a bagging rejection clamp 332, a bagging rejection moving assembly 333, a bagging rejection lifting assembly 334, a bagging rejection driving assembly 335, and a bagging rejection suction cup 336. The bagging rejection clamp 332 includes two opposing bagging rejection plates 3321, which are movably connected to the bagging rejection base 331 via adjusting grooves, adjusting holes, and bolts. The bagging rejection lifting assembly 334 is connected to the bagging rejection moving assembly 333 via a slider. The bagging rejection moving assembly 333 is a linear slide rail commonly used in the market. Both the bagging rejection lifting assembly 334 and the bagging rejection driving assembly 335 are cylinders. The bagging rejection driving assembly 335 is connected to the output end of the bagging rejection lifting assembly 334, and the bagging rejection suction cup 336 is connected to the output end of the bagging rejection driving assembly 335.

[0050] In the previous process, the box-flipping gripper 2312 rotated the battery cell assembly 5 90 degrees, making it vertical. At this time, there were still plastic bags left over from the cutting process on the battery cell assembly 5. After the transport gripper 311 moved above the rejection platform 234 and clamped the vertically positioned battery cell assembly 5, the box-flipping gripper 2312 released its grip on the battery cell assembly 5. Then, the transport gripper 311 moved the battery cell assembly 5 above the bag rejection base 331 and placed the battery cell assembly 5 between the two bag rejection clamps 3321. Then, the bag rejection moving component 333 moved the bag rejection suction cup 336 to the side of the battery cell assembly 5, and the bag rejection driving component 335 drove the bag rejection suction cup 336 to move closer to the battery cell assembly 5, adsorbing the remaining plastic bags through the bag rejection suction cup 336. Then, the bag-removing lifting assembly 334 moves the bag-removing suction cup 336 upward, causing the plastic bag to detach from the battery cell assembly 5. Next, the bag-removing moving assembly 333 moves the bag-removing suction cup 336 away from the battery cell assembly 5. Finally, the bag-removing lifting assembly 334 moves the bag-removing suction cup 336 downward, causing the suction cup 336 to release its grip on the plastic bag. A waste conveyor line 24 is also provided below the bag-removing device 33, and the plastic bag falls onto the waste conveyor line 24 and is conveyed out.

[0051] After the plastic bag is removed, the battery cell assembly 5 on the bag removal base 331 is then transported by the transport gripper 311 to the material removal device 32, and the hollow board, pearl cotton and sulfur-free paper laid on both sides of the battery cell assembly 5 are removed by the material removal mechanism 321.

[0052] like Figure 8 As shown, the material rejection device 32 also includes a material rejection base 323, on which a material rejection clamp 324 is movably connected. Specifically, the material rejection clamp 324 can be movably connected to the material rejection base 323 via an adjustment groove, an adjustment hole, and bolts. A baffle 325 is also fixed on the material rejection clamp 324 for support, preventing the pearl cotton and sulfur-free paper from collapsing due to their softness and thinness.

[0053] The material rejection mechanism 321 also includes material rejection grippers 3212 and four material rejection suction cups 3211, which are respectively mounted on two material rejection grippers 3212. The material rejection moving mechanism 322 can drive the material rejection suction cups 3211 to move relative to the material rejection fixture 324 in the horizontal and vertical directions.

[0054] The material rejection moving mechanism 322 includes a material rejection horizontal moving component 3221 and a material rejection lifting component 3222. The material rejection lifting component 3222 and the material rejection horizontal moving component 3221 are slidably connected by a slider. The material rejection horizontal moving component 3221 is a conventional linear module, and the material rejection lifting component 3222 is a cylinder. The material rejection gripper 3212 is controlled by a finger cylinder to open and close. The material rejection gripper 3212 is connected to the output end of the material rejection lifting component 3222 and is driven to rise and fall by the material rejection lifting component 3222.

[0055] In one embodiment, a sensor 326 is also installed on the material rejection fixture 324. This sensor 326 can be a fiber optic sensor currently used in the market. The light emitted by the sensor 326 can be reflected back after contacting the hollow board, pearl cotton, sulfur-free paper, and battery cells. The intensity of the reflected light is used to determine whether the hollow board, pearl cotton, and sulfur-free paper have been completely rejected.

[0056] The material rejection device 32 also includes a fixed suction cup mechanism 327, which is located at one end of the material rejection fixture 324. The fixed suction cup mechanism 327 includes a fixed gripper 3271, a fixed suction cup, and a gripper drive 3272. The fixed gripper 3271 is connected to the gripper drive 3272, and the gripper drive 3272 controls the opening and closing of the fixed gripper 3271. The fixed suction cup is fixed to the fixed gripper 3271.

[0057] Preferably, the gripper drive 3272 is a finger cylinder, and the fixed gripper 3271 is connected to the output end of the finger cylinder by screws. There are two fixed suction cups, which are respectively fixed to the two fixed grippers 3271 by screws. The gripper drive 3272 can be fixed to the material rejection fixture 324 by screws.

[0058] When the material rejection device 32 of this application is in operation, the transport gripper 311 first moves the battery cell assembly 5 on the bag rejection base 331 to the material rejection base 323, and the material rejection clamp 324 limits and supports the battery cell assembly 5. Then, the material rejection horizontal moving component 3221 and the material rejection lifting component 3222 drive the material rejection gripper 3212 to a predetermined position, and then control the material rejection gripper 3212 to close, and the hollow plate is picked up by the material rejection suction cup 3211. After picking up the hollow plate, the material rejection lifting component 3222 drives the material rejection suction cup 3211 and the hollow plate to move upward. Next, the material rejection horizontal moving component 3221 drives the material rejection suction cup 3211 and the hollow plate to move laterally away from the battery cell assembly 5. After the hollow plate is pulled out from the side of the battery cell assembly 5, the material rejection suction cup 3211 stops adsorbing the hollow plate, allowing it to fall downwards and be conveyed out by the waste conveyor belt. Following the same method of adsorbing the hollow plate, pearl cotton and sulfur-free paper are then sequentially adsorbed and conveyed out by the waste conveyor belt.

[0059] During the process of picking up the hollow sheet and moving it horizontally, the EPE foam can be fixed in place using a suction cup to prevent it from moving with the hollow sheet and affecting subsequent EPE foam adsorption. Similarly, after picking up the EPE foam, the sulfur-free paper can be fixed in place using a suction cup to prevent it from moving with the EPE foam and affecting subsequent sulfur-free paper adsorption.

[0060] like Figure 7 , Figure 9 As shown, after removing the hollow board, pearl cotton, and sulfur-free paper, the cell assembly 5 is transported to the cell alignment device 34 by the transport gripper 311 for alignment. To achieve cell alignment, the cell alignment device 34 includes a cell alignment base 341, an upper alignment mechanism 342, a left alignment mechanism 343, and a right alignment mechanism 344. The cell alignment base 341 has an alignment clamp 345, which can also be movably connected to the cell alignment base 341 via an adjustment slot, adjustment hole, and bolts. The transport gripper 311 directly transports the cell assembly 5 to be aligned onto the cell alignment base 341, and the alignment clamp 345 limits and supports the cell assembly 5.

[0061] During alignment, the upper alignment mechanism 342 first aligns the battery cell assembly 5. The upper alignment mechanism 342 includes upper alignment grippers 3421, an upper air blade 3422, an upper alignment lifting assembly 3423, and an upper alignment horizontal movement assembly 3424. The upper alignment lifting assembly 3423 and the upper alignment horizontal movement assembly 3424 are slidably connected via sliders, and the upper alignment plate is slidably connected to the upper alignment assembly 3423 via sliders. There are three upper air blades 3422 and three upper alignment grippers 3421, all of which are fixed to the upper alignment plate. A sponge pad 346 of suitable hardness can also be fixed to the upper alignment grippers 3421 by adhesive or other means. The upper alignment lifting assembly 3423 and the upper alignment horizontal movement assembly 3424 are existing linear modules.

[0062] When the upper alignment mechanism 342 is performing alignment, the battery cell assembly 5 can be loosened by blowing air through the three upper air blades 3422. Then, the battery cells are pressed by the sponge pads 346 on the three upper alignment claws 3421, and the upper and lower surfaces of the battery cells are aligned by gravity.

[0063] The left alignment mechanism 343 includes a left alignment gripper 3431, a left air blade 3432, a left alignment lateral movement component 3433, and a left alignment longitudinal movement component 3434. The left alignment longitudinal movement component 3434 is slidably connected to the left alignment lateral movement component 3433 via a slider, and its output end is connected to a left alignment plate. There are three left alignment grippers 3431 and three left air blades 3432, all fixed to the left alignment plate. The left alignment lateral movement component 3433 is a conventional linear module, and the left alignment longitudinal movement component 3434 is a cylinder. A sponge pad 346 is attached to the left alignment gripper 3431. The left alignment gripper 3431 is located on the left side of the alignment fixture 345.

[0064] The right alignment mechanism 344 includes a right alignment gripper 3441, a right air knife 3442, a right alignment lateral movement component 3443, and a right alignment longitudinal movement component 3444. The right alignment longitudinal movement component 3444 is slidably connected to the right alignment lateral movement component 3443 via a slider, and its output end is connected to a right alignment plate. There are three right alignment grippers 3441 and three left air knives 3432, all fixed to the right alignment plate. The right alignment lateral movement component 3443 is a conventional linear module, and the right alignment longitudinal movement component 3444 is a cylinder. A sponge pad 346 is attached to the right alignment gripper 3441. The right alignment gripper 3441 is located on the left side of the alignment fixture 345. The air vents of the left air knife 3432 and the right air knife 3442 are staggered.

[0065] The bagging rejection base 331, the material rejection base 323, and the cell alignment base 341 all have perforated grooves 347. During transportation, the cell assembly 5 may break into fragments, which can fall directly onto the waste conveyor line 24 through the perforated grooves 347. The cell alignment base 341 may also be equipped with two lower air blades, with their air inlets staggered with those of the upper air blade 3422. The air inlets of the lower air blades can be located within the perforated grooves 347.

[0066] When aligning the battery cell assembly 5, air is first blown onto the assembly 5 using the upper air blade 3422, lower air blade, left air blade 3432, and right air blade 3442 to separate the battery cell assembly 5 and reduce friction between adjacent cells during alignment. Then, the upper alignment gripper 3421, left alignment gripper 3431, and right alignment gripper 3441 gently compress the battery cell assembly 5 to align it. The upper air blade 3422, lower air blade, left air blade 3432, and right air blade 3442 can all be air blades currently available on the market.

[0067] A fiber optic sensor is also installed on the cell alignment base 341 to detect the front and back of the cell, thereby facilitating the subsequent flipping of the cell assembly 5.

[0068] After the battery cell assembly 5 is aligned, it is then gripped by two transport jaws 311 connected to the flipping shaft 3133, and flipped from a vertical position to a horizontal position. The battery cell assembly 5 can be flipped clockwise or counterclockwise, and the specific flipping direction can be determined based on the detection results of the fiber optic sensor 348326.

[0069] In one embodiment, such as Figure 3 As shown, the unpacking system for the battery cell packaging box also includes a hopper return device 6, which is located at the front end of the waste removal device 3. After the battery cell assembly 5 is aligned, it is then transported to the hopper return device 6 to be conveyed out.

[0070] like Figure 2 , Figure 3 As shown, the hopper return device 6 includes a rotary gripping device 61 and a discharge device 62. The rotary gripping device 61 includes a rotary moving mechanism 611 and a rotary gripping robot 612. The rotary gripping robot 612 is connected to the rotary moving mechanism 611, and the rotary moving mechanism 611 drives the rotary gripping robot 612 to move in the horizontal and vertical directions.

[0071] Specifically, such as Figure 13As shown, the rotary moving mechanism 611 includes a rotary horizontal moving component 6111 and a rotary vertical moving component 6112. The rotary vertical moving component 6112 is slidably connected to the rotary horizontal moving component 6111 via a slider. Both the rotary horizontal moving component 6111 and the rotary vertical moving component 6112 are existing linear modules.

[0072] The rotary gripping robot 612 includes a rotary gripping base 6121, a gripping drive component 6122, a gripping linkage assembly 6123, and four rotary grippers 6124. The rotary gripping base 6121 and the rotary vertical movement assembly 6112 are slidably connected via a slider, and the gripping drive component 6122 is mounted on the rotary gripping base 6121. The gripping drive component 6122 is a servo motor.

[0073] like Figure 13 , Figure 14 As shown, the clamping linkage assembly 6123 includes a linkage fixing plate 61231, a linkage rotating plate 61232, four linkage connecting parts 61233, and four linkage slide rails 61234. The linkage fixing plate 61231 is connected to the rotary clamping fixing seat 6121, and the linkage rotating plate 61232 is rotatably connected to the linkage fixing plate 61231 via a rotating shaft. The output end of the clamping drive component 6122 is connected to the linkage rotating plate 61232. When the clamping drive component 6122 is activated, it can drive the linkage rotating plate 61232 to rotate.

[0074] Four mutually perpendicular slide rails 61234 are fixed on the linkage fixing plate 61231, and four rotary grippers 6124 are slidably connected to the four slide rails 61234 respectively. Four evenly distributed linkage connecting blocks 61235 are located along the outer circumference of the linkage rotating plate 61232. One end of each of the four linkage connecting members 61233 is movably connected to one of the four linkage connecting blocks 61235, and the other end of each linkage connecting member 61233 is connected to one of the four rotary grippers 6124 respectively. During the rotation of the linkage rotating plate 61232 driven by the clamping drive member 6122, the four rotary grippers 6124 can slide on the four slide rails 61234 respectively, thereby controlling the opening and closing of the four rotary grippers 6124.

[0075] The linkage connector 61233 can be a commercially available pull rod ball joint assembly, where both ends of the pull rod have fisheye ball joints. The pull rod is connected to the linkage connector 61235 and the rotary gripper 6124 via the fisheye ball joints. When the linkage rotating plate 61232 rotates, the rotational motion is converted into four linear motions in different directions through the linkage connector 61233, thereby controlling the opening and closing of the four rotary grippers 6124. In one embodiment, the pull rod can be a forward or reverse thread adjustable pull rod, where the length of the pull rod can be adjusted by left-hand or right-hand thread, thereby adjusting the position of the rotary gripper 6124.

[0076] like Figure 3 and Figure 12 As shown, the discharge device 62 includes a discharge conveyor line 621 and a hopper rotation mechanism 622. The rotary gripping robot 612 is located above the feed end of the discharge conveyor line 621, and the hopper rotation mechanism 622 is located in the middle of the discharge conveyor line 621. The hopper rotation mechanism 622 can drive the hopper 623 to rotate.

[0077] After the transport gripper 311 clamps the battery cell assembly 5 and flips it from a vertical to a horizontal position, the rotary moving mechanism 611 drives the rotary gripping robot 612 to move above the battery cell assembly 5, and the gripping drive 6122 drives the linkage rotating plate 61232 to rotate. During the rotation of the linkage rotating plate 61232, the four rotary grippers 6124 simultaneously slide along the slide rail 61234 through the four linkage connectors 61233, causing the rotary gripping robot 612 to close and clamp the battery cell assembly 5. Then, the rotary moving mechanism 611 drives the battery cell assembly 5 to move above the hopper rotating mechanism 622 and places the battery cell assembly 5 into the hopper 623. Two sets of battery cell assemblies 5 are placed in one hopper 623, and each set of battery cell assemblies 5 contains one hundred and twenty battery cells. When the transport gripper 311 flips the cell assembly 5, it adjusts the position of the front and back of the cell to ensure that the cell assemblies 5 in the same hopper 623 are placed in the same position.

[0078] The hopper 623 is placed on the discharge conveyor line 621 and is moved forward by the discharge conveyor line 621. The discharge conveyor line 621 can also be an existing material conveyor line. The discharge conveyor line 621 uses two conveyor belts to transport the hopper 623. The conveyor belts are driven by a motor.

[0079] The hopper 623 in this application can be an existing hopper for transferring solar cells. For example... Figure 3 , Figure 12 As shown, in order to transport the hopper 623 to the discharge conveyor line 621, the hopper return equipment 6 also includes a hopper inlet conveyor line 624 and a hopper lifting device 625. The hopper inlet conveyor line 624 is located below the discharge conveyor line 621. The hopper lifting device 625 is located at the discharge end of the hopper inlet conveyor line 624. After the hopper 623 is transported by the hopper inlet conveyor line 624 to the hopper lifting device 625, it can be transported to the inlet end of the discharge conveyor line 621 through the hopper lifting device 625. The hopper inlet conveyor line 624 is also a conventional material conveying conveyor line. This hopper inlet conveyor line 624 uses two conveyor belts to transport the hopper 623, and the conveyor belts are driven by motors.

[0080] The hopper lifting device 625 includes a lifting mechanism 6251 and a lifting conveyor line 6252. The lifting conveyor line 6252 is connected to the lifting mechanism 6251. The lifting mechanism 6251 drives the lifting conveyor line 6252 to rise and fall. The lifting conveyor line 6252 is located at the inlet end of the discharge conveyor line 621. The lifting mechanism 6251 is a conventional linear module. The lifting conveyor line 6252 is a conventional material conveyor line, which achieves conveying by moving a conveyor belt driven by a motor. The lifting conveyor line 6252 can be mounted on a lifting plate, which is slidably connected to the lifting mechanism 6251 via a slider. The hopper rotation mechanism 622 is located at the inlet end of the discharge conveyor line 621. The hopper rotation mechanism 622 includes a rotating platform 6221, a rotating cylinder 6222, and a rotating lifting cylinder. The output end of the rotating cylinder 6222 is connected to the rotating platform 6221, driving the rotating platform 6221 to rotate in the middle of the discharge conveyor line 621. The output end of the rotating lifting cylinder is connected to the rotating cylinder 6222, driving both the rotating cylinder 6222 and the rotating platform 6221 to rotate.

[0081] To align the hopper 623, the discharge device 62 also includes a hopper alignment mechanism 626. The hopper alignment mechanism 626 comprises five hopper alignment components 6261, with two components fixed to the left and right sides of the discharge conveyor line 621 respectively. The third hopper alignment component 6261 is located at the feed end of the discharge conveyor line 621, and this component can be raised and lowered by a cylinder. The hopper alignment component 6261 includes a hopper alignment cylinder 62611 and a hopper alignment plate 62612. The hopper alignment cylinder 62611 is fixed to the discharge conveyor line 621, and its output end is connected to the hopper alignment plate 62612.

[0082] After being fed into the feed end of the hopper 623 conveyor line, the empty hopper 623 is conveyed to the discharge end of the hopper 623 conveyor line and directly to the lifting conveyor line 6252. Then, the lifting mechanism 6251 lifts the hopper 623. The lifting conveyor line 6252 then conveys the hopper 623 to the discharge conveyor line 621, and on the discharge conveyor line 621, it is conveyed above the rotating platform 6221. Next, a rotary lifting cylinder lifts the rotating platform 6221, raising the hopper 623 from the discharge conveyor line 621, and the rotary cylinder 6222 rotates the hopper 623. Once the hopper 623 has rotated to a predetermined angle, five hopper alignment components 6261 then align the hopper 623.

[0083] After the hopper 623 is aligned, the rotary lifting cylinder drives the rotating platform 6221 to descend, placing the hopper 623 on the discharge conveyor line 621. Then, the rotary gripping robot 612 can place the gripped battery cell assembly 5 into the hopper 623. The bottom of the hopper 623 is padded with sponge. The first set of battery cell assemblies 5 is placed on the sponge. When placing the second set of battery cell assemblies 5, the rotary gripping robot 612 moves the battery cell assembly 5 to 1mm above the first set of battery cell assemblies 5 and releases it, allowing the battery cell assembly 5 to fall freely, avoiding the possibility of the battery cells being crushed during placement.

[0084] After the battery cell assembly 5 is placed, the hopper 623 is then transported out by the discharge conveyor line 621. The discharge end of the hopper 623 conveyor line can be connected to an AGV or other transfer conveyor line to transport the hopper 623 out.

[0085] A CCD camera can be installed on one side of the lifting conveyor line 6252. The CCD camera conveys the material bin 623 and identifies the placement direction of the material bin 623. The rotary cylinder 6222 adjusts the position of the material bin 623 according to the identified direction of the material bin 623 to ensure the correct placement of the battery cell grid lines in the material bin 623.

[0086] A workbench can also be placed on one side of the discharge conveyor line 621, where workers can stand and work to handle any issues such as broken battery cells.

[0087] The gripping suction cup 2321, material rejection suction cup 3211, bag rejection suction cup 336, and fixing suction cup of this application all achieve adsorption through the principle of vacuum adsorption. Sponge pads 346 can be attached to the handling gripper 311, the flipping gripper, and the rotating gripper 6124 to provide cushioning and prevent damage to the battery cells.
