[0080] Before the battery cell 03 is transported, multiple battery cells 03 will be packaged in the battery box 02, such as... Figure 2 As shown, the battery box 02 is a box-shaped component with an opening, which is sealed by a sealing film 04 to reduce the risk of the battery cells 03 detaching from the battery box 02 during transportation. Figure 1 As shown, multiple battery boxes 02 are encapsulated inside a packaging box 01. The packaging box 01 includes a box body and a box cover. The box cover is placed on the box body, and the box cover and box body are sealed and fixed by sealing tape.

[0081] The first aspect of this application provides an unpacking and loading device for unpacking and loading battery cells 03, such as... Figure 3 and Figure 4As shown, the unpacking and loading device includes an operating platform 1, a separating device 2, a flipping device 3, a first loading device 4, a film-cutting device 5, and a second loading device 6. The operating platform 1 is used to support the packaging box 01. At least a portion of the separating device 2 is distributed along the height direction Z of the unpacking and loading device with the operating platform 1. The separating device 2 is used to separate the box body from the box cover. At least a portion of the flipping device 3 is distributed along the height direction Z of the unpacking and loading device with the operating platform 1. The flipping device 3 is used to flip the box body at a preset angle. At least a portion of the first loading device 4 is distributed along the height direction Z of the unpacking and loading device with the operating platform 1. The first loading device 4 is used to move the battery box 02 inside the box body onto the operating platform 1. At least a portion of the film-cutting device 5 is distributed along the height direction Z of the unpacking and loading device with the operating platform 1. The film-cutting device 5 is used to break the sealing film 04. At least a portion of the second loading device 6 is distributed along the height direction Z of the unpacking and loading device with the operating platform 1. The second loading device 6 is used to move the battery cells 03 inside the battery box 02 to the next process.

[0082] During the operation of the unpacking and loading device, the packaging box 01 is first placed on the operating platform 1. At this time, the packaging box 01 contains multiple battery boxes 02, and the battery boxes 02 contain multiple battery cells 03. The packaging box 01 is then moved to the bottom of the separating device 2. The separating device 2 separates the box body from the box cover. Then, the flipping device 3 flips the packaging box 01 to a preset angle so that the opening of the packaging box 01 faces the first loading device 4. The first loading device 4 takes out the battery boxes 02 from the packaging box 01 and places them on the operating platform 1. After that, the battery boxes 02 are moved to the bottom of the film cutting device 5. The film cutting device 5 cuts the sealing film 04 at the opening of the battery box 02 to expose the battery cells 03. Finally, the second loading device 6 moves the battery cells 03 in the battery boxes 02 to the next process to complete the unpacking and loading of the battery cells 03.

[0083] The unpacking and loading device can automatically unpack the packaging box 01 and battery box 02, and also automatically load the battery cells 03. This simplifies the unpacking and loading operation of the battery cells 03, thereby reducing the labor cost of unpacking and loading the battery cells 03. At the same time, it helps to shorten the unpacking and loading cycle of the battery cells 03 and improve the unpacking and loading efficiency. In addition, it reduces the risk of damaging the battery cells 03 during manual unpacking and loading, thereby improving the unpacking yield of the battery cells 03. The flipping device 3 is set so that the opening of the packaging box 01 can face the first loading device 4, thereby simplifying the operation of the first loading device 4 to remove the battery box 02 from the packaging box 01. This simplifies the structure of the first loading device 4 and shortens the time for the first loading device 4 to remove the battery box 02 from the packaging box 01, thereby further shortening the unpacking and loading cycle of the battery cells 03.

[0084] like Figure 3 , Figure 4 and Figure 5 As shown, the separation device 2 includes a first mounting frame 21 and a separation component 22. The separation component 22 is mounted on the first mounting frame 21 and can move relative to the first mounting frame 21 toward or away from the operating platform 1. The separation component 22 is used to break the sealing tape to separate the box body from the box cover.

[0085] After the packaging box 01 moves to the bottom of the separating device 2, the separating component 22 can move relative to the first mounting frame 21 toward the packaging box 01, causing the separating component 22 to break the sealing tape. After that, the separating component 22 can move relative to the first mounting frame 21 away from the packaging box 01 to increase the distance between the separating component 22 and the packaging box 01, thereby facilitating the movement of the packaging box 01 to the flipping device 3. This reduces the risk of interference between the packaging box 01 and the separating component 22 during the movement, which could cause damage to the separating component 22 or the packaging box 01. This extends the service life of the separating component 22 and helps improve the working stability of the separating component 22 in the next process.

[0086] The separating component 22 can be a cutter, that is, as the separating component 22 moves toward the packaging box 01, the separating component 22 can cut the sealing tape, thereby reducing the cost of the separating component 22 and reducing the energy consumption and cost of the separating component 22 breaking the sealing tape; the separating component 22 can also be a heating rod, that is, as the separating component 22 moves toward the packaging box 01, the separating component 22 can heat and melt the sealing tape.

[0087] During the process of the separator 22 cutting the sealing tape, the separator 22 can move along the length and / or width of the packaging box 01, and / or, the separator 22 extends along the length of the packaging box 01 and is positioned opposite to the packaging box 01 along the width, and / or, the separator 22 extends along the width of the packaging box 01 and is positioned opposite to the packaging box 01 along the length, so that the separator 22 can cut the sealing tape circumferentially along the packaging box 01, thereby improving the working reliability of the separator 22.

[0088] like Figure 4 and Figure 5As shown, the second support includes at least a first frame 211 and a second frame 212. The first frame 211 and the second frame 212 are mounted on the operating platform 1, or they are mounted on the ground. Along the width direction Y of the operating platform 1, the first frame 211 and the second frame 212 are arranged opposite each other on both sides of the operating platform 1. The two ends of the separator 22 are respectively connected to the first frame 211 and the second frame 212. The arrangement of the first frame 211 and the second frame 212 increases the stability of the installation structure of the separator 22 and reduces the risk of shaking and displacement of the separator 22, thereby improving the working stability and reliability of the separator 22.

[0089] After the sealing tape breaks off at the separating component 22, the lid can be picked up by a robotic arm or adsorbed by a suction cup and removed from the box body to separate the box body and the lid, thus exposing the battery box 02; alternatively, the box body and the lid can be separated by the automatic detachment of the lid during the flipping process of the flipping device 3 flipping the packaging box 01.

[0090] In one embodiment, such as Figure 3 and Figure 5 As shown, the flipping device 3 includes a first base 31, a first cantilever 32 and a first gripper 33. One side of the first cantilever 32 is connected to the first base 31 and the other side is connected to the first gripper 33. The first cantilever 32 can drive the first gripper 33 to move towards or away from the operating platform 1. The first gripper 33 is used to hold the box and flip the box by a preset angle.

[0091] During the flipping process of the flipping device 3, the first gripper 33 can hold one side of the packaging box 01, for example, the first gripper 33 holds the left side of the packaging box 01 near the end. Then, along the height direction Z of the unpacking and feeding device, the first cantilever 32 drives the first gripper 33 to move away from the operating platform 1, causing the left end of the packaging box 01 to rotate away from the operating platform 1, thereby realizing the rotation of the packaging box 01 and changing the orientation of the opening of the packaging box 01. By using the first gripper 33 to hold the end of the packaging box 01 to achieve rotation, the stability of the gripping of the packaging box 01 is increased during the flipping process of the flipping device 3, thereby improving the working stability and reliability of the flipping device 3.

[0092] In another embodiment, such as Figure 8 and Figure 9As shown, the flipping device 3 has a windmill-like structure, meaning it includes a rotating shaft 34 and multiple trays 35 spaced circumferentially along the shaft 34. The trays 35 support the packaging box 01, and the rotating shaft 34 can drive the trays 35 to rotate around its central axis, thereby flipping the packaging box 01. Setting the flipping device 3 as a windmill-like structure simplifies its structure, thus helping to reduce material costs, processing costs, and installation costs.

[0093] like Figure 3 , Figure 5 and Figure 6 As shown, the first feeding device 4 includes a second base 41, a second cantilever 42, and a second gripper 43. One side of the second cantilever 42 is connected to the second base 41, and the other side is connected to the second gripper 43. The second cantilever 42 can drive the second gripper 43 to move towards or away from the operating platform 1. At least a portion of the second gripper 43 is used to extend into the housing to grip the battery box 02. The second gripper 43 is also used to place the battery box 02 on the operating platform 1.

[0094] After the flipping device 3 flips the packaging box 01 so that the opening of the packaging box 01 faces the first feeding device 4, the second cantilever 42 drives the second gripper 43 to move closer to the packaging box 01, so that at least part of the second gripper 43 extends into the packaging box 01 and clamps and fixes the battery box 02. After that, the second cantilever 42 drives the second gripper 43 to move away from the packaging box 01, so that the battery box 02 is removed from the packaging box 01 and placed on the operating platform 1.

[0095] By using the second gripper 43 to grip the battery box 02, the difficulty of the first feeding device 4 in removing the battery box 02 from the packaging box 01 is reduced, thereby simplifying the structure of the first feeding device 4 and reducing the material cost, processing cost and installation cost of the first feeding device 4. At the same time, by using the second gripper 43 to grip the battery box 02, the risk of damaging the encapsulation film 04 during the process of the first feeding device 4 moving the battery box 02 is reduced, thereby improving the stability of the battery cell 03 encapsulated in the battery box 02.

[0096] like Figure 3 , Figure 4 and Figure 5 As shown, the film breaking device 5 includes a second mounting frame 51 and a film breaking component 52. The film breaking component 52 is mounted on the second mounting frame 51 and can move relative to the second mounting frame 51 in a direction closer to or further away from the operating platform 1. The film breaking component 52 is used to break the sealing film 04.

[0097] After the packaging box 01 moves to the bottom of the film-cutting device 5, the film-cutting component 52 can move relative to the second mounting bracket 51 toward the direction closer to the battery box 02, so that the film-cutting component 52 breaks the sealing film 04. After that, the film-cutting component 52 can move relative to the second mounting bracket 51 toward the direction away from the battery box 02, so as to increase the distance between the film-cutting component 52 and the battery box 02, thereby facilitating the movement of the battery box 02 to the second feeding device 6. This reduces the risk of interference between the battery box 02 and the film-cutting component 52 during the movement, which may cause damage to the film-cutting component 52 or the battery box 02, thereby extending the service life of the film-cutting component 52 and improving the working stability of the film-cutting component 52 in the next process.

[0098] The film-cutting component 52 can be a cutter, that is, as the film-cutting component 52 moves toward the battery box 02, the film-cutting component 52 can cut the encapsulation film 04, thereby reducing the cost of the film-cutting component 52 and reducing the energy consumption and cost of the film-cutting component 52 breaking the encapsulation film 04; the film-cutting component 52 can also be a heating rod, that is, as the film-cutting component 52 moves toward the battery box 02, the film-cutting component 52 can heat and melt the encapsulation film 04.

[0099] like Figure 4 and Figure 6 As shown, the second support includes at least a third frame 511 and a fourth frame 512. The third frame 511 and the fourth frame 512 are mounted on the operating platform 1, or they are mounted on the ground. Along the width Y direction of the operating platform 1, the third frame 511 and the fourth frame 512 are positioned opposite each other on both sides of the operating platform 1. The two ends of the film-cutting component 52 are respectively connected to the third frame 511 and the fourth frame 512. The arrangement of the third frame 511 and the fourth frame 512 increases the stability of the installation structure of the film-cutting component 52, reduces the risk of swaying and displacement of the film-cutting component 52, and thus helps to improve the working stability and reliability of the film-cutting component 52.

[0100] like Figure 3 and Figure 6 As shown, the second feeding device 6 includes a third base 61, a third cantilever 62, and a feeding component 63. One side of the third cantilever 62 is connected to the third base 61, and the other side is connected to the feeding component 63. The feeding component 63 is a third gripper, at least a portion of which is used to extend into the battery box 02 to grip the battery cell 03. The third gripper is also used to place the battery cell into the next process. Alternatively, the feeding component 63 is a suction cup, which is used to adsorb the battery cell 03 and place the battery cell 03 into the next process.

[0101] After the battery box 02 is moved to the second feeding device 6, the third cantilever 62 drives the feeding component 63 to move closer to the battery box 02, so that at least part of the feeding component 63 extends into the packaging box 01 and clamps or adsorbs the battery cell 03. After that, the third cantilever 62 drives the feeding component 63 to move away from the battery box 02, so that the battery cell 03 is removed from the battery box 02 and moved to the next process.

[0102] By using the feeding component 63 to clamp or adsorb the battery cell 03, the difficulty of removing the battery cell 03 from the battery box 02 by the second feeding device 6 is reduced, thereby simplifying the structure of the second feeding device 6 and reducing the material cost, processing cost and installation cost of the second feeding device 6. At the same time, by using the feeding component 63 to clamp or adsorb the battery cell 03, the risk of scratching or damaging the battery cell 03 during the manual removal and feeding process is reduced, thereby improving the yield of unpacking and feeding the battery cell 03.

[0103] In any of the above embodiments, such as Figure 4 As shown, the operating platform 1 includes a first base 11, a second base 12, a first rotating wheel 13, a second rotating wheel 14, and a first conveyor belt 15. The first base 11 and the second base 12 are arranged opposite each other along the length direction X of the first conveyor belt 15. The first rotating wheel 13 is rotatably mounted on the first base 11, and the second rotating wheel 14 is rotatably mounted on the second base 12. The first conveyor belt 15 is wound around the first rotating wheel 13 and the second rotating wheel 14. The first rotating wheel 13 and the second rotating wheel 14 can drive the first conveyor belt 15 to rotate along the length direction X of the first conveyor belt 15.

[0104] The rotation of the first conveyor belt 15 drives the movement of the packaging box 01 and battery box 02 on the first conveyor belt 15, reducing the difficulty of moving the packaging box 01 and battery box 02 between the separation device 2, the flipping device 3, the first feeding device 4, the film cutting device 5 and the second feeding device 6. This simplifies the overall structure of the unpacking and feeding device, reduces the processing cost, installation cost and operation and maintenance cost of the unpacking and feeding device, and at the same time, it is conducive to realizing the automated operation of unpacking and feeding of battery cells 03, reducing the labor cost in the operation of the unpacking and feeding device.

[0105] Given that the first conveyor belt 15 can move the packaging box 01 and the battery box 02 along its own length direction X, the unpacking and loading device also includes a positioning component. When the packaging box 01 moves to the separating device 2, at least a portion of the positioning component can abut against the packaging box 01, and / or, when the packaging box 01 moves to the first loading device 4, at least a portion of the positioning component can abut against the packaging box 01 to limit the movement of the packaging box 01 in the length direction X of the first conveyor belt 15, and / or, when the battery box 02 moves to the film-cutting device 5 ... At least a portion of the positioning component can abut against the battery box 02, and / or, when the battery box 02 moves to the film cutting device 5, at least a portion of the positioning component can abut against the battery box 02, and / or, when the battery box 02 moves to the second feeding device 6, at least a portion of the positioning component can abut against the battery box 02, thereby restricting the movement of the battery box 02 in the length direction X of the first conveyor belt 15, thereby improving the working stability and reliability of the separation device 2, the first feeding device 4, the film cutting device 5 and the second feeding device 6, and further improving the unpacking and feeding yield of the unpacking and feeding device.

[0106] like Figure 3 , Figure 5 and Figure 6 As shown, the unpacking and feeding device also includes a position detector 7 and a control system. The position detector 7 is disposed on at least one of the operating platform 1, the separation device 2, the flipping device 3, the first feeding device 4, the film cutting device 5, and the second feeding device 6. The position detector 7 is electrically or signal-connected to the control system. The control system is electrically or signal-connected to the separation device 2, the flipping device 3, the first feeding device 4, the film cutting device 5, and the second feeding device 6, respectively. The position detector 7 is used to detect the position of the battery cell 03 on the operating platform 1. The control system is used to control at least one of the separation device 2, the flipping device 3, the first feeding device 4, the film cutting device 5, and the second feeding device 6 to work according to the detection result of the position detector 7.

[0107] For example, there are multiple position detectors 7, and along the length direction X of the first conveyor belt 15, the position detectors 7 are located in front of the separation device 2, in front of the flipping device 3, in front of the first feeding device 4, in front of the film cutting device 5, and in front of the second feeding device 6. Taking the separation device 2 as an example, as the packaging box 01 moves towards the separation device 2 along the length direction X of the first conveyor belt 15, the packaging box 01 will first pass the position detector 7. At this time, the position detector 7 can transmit the position information of the packaging box 01 to the control system. The control system determines that the battery box has reached the working position of the separation device 2 based on the received signal, and controls the separation device 2 to work so that the separation device 2 can cut the packaging tape.

[0108] The installation of position sensors and a control system facilitates the control of the working status of the separation device 2, the flipping device 3, the first feeding device 4, the film cutting device 5, and the second feeding device 6. This improves the accuracy and reliability of the operation of the separation device 2, the flipping device 3, the first feeding device 4, the film cutting device 5, and the second feeding device 6, and reduces the risk of energy waste caused by the continuous operation of the separation device 2, the flipping device 3, the first feeding device 4, the film cutting device 5, and the second feeding device 6. This reduces the operating cost of the unpacking and feeding device. In addition, it facilitates the automation of the unpacking and feeding device, reducing the difficulty of operation and labor costs.

[0109] like Figure 3 As shown, the operating platform 1 includes at least a first platform 16 and a second platform 17, which are spaced apart. At least a portion of the separation device 2 is distributed along the height direction Z of the unpacking and feeding device with the first platform 16. At least a portion of the film cutting device 5 is distributed along the height direction Z of the unpacking and feeding device with the second platform 17. The first feeding device 4 is used to move the battery box 02 in the box on the first platform 16 to the second platform 17.

[0110] The arrangement of first platforms 16 and second platforms 17, which are spaced apart along the length direction X of the first conveyor belt 15, reduces the required length of the first conveyor belt 15, and helps to improve the overall structural strength of the operating platform 1, improve the working stability of the operating platform 1, and help to reduce the material and processing costs of the operating platform 1. At the same time, it helps to reduce the overall weight of the operating platform 1, so as to facilitate the transportation and installation of the operating platform 1.

[0111] like Figure 4 As shown, the unpacking and loading device also includes a first storage box and a second storage box 8. The first storage box is located between the first platform 16 and the second platform 17 and is used to store the box body. The second storage box 8 is located on the side of the second platform 17 away from the first platform 16 and is used to store the battery box 02.

[0112] After all the battery boxes 02 inside the packaging box 01 are removed, the packaging box 01 can move along the first conveyor belt 15 on the first platform 16 until it falls into the first storage box, thus completing the recycling of the packaging box 01 and facilitating its reuse. Similarly, after all the battery cells 03 inside the battery box 02 are removed, the battery box 02 can move along the first conveyor belt 15 on the second platform 17 until it falls into the second storage box 8, thus completing the recycling of the battery box 02 and facilitating its reuse, thereby reducing the packaging cost of the battery cells 03. Positioning the first storage box between the first platform 16 and the second platform 17 facilitates the automatic falling of the packaging box 01 into it. Positioning the second storage box 8 on the side of the second platform 17 away from the first platform 16 facilitates the automatic falling of the battery boxes 02 into it, thus simplifying the operation of the unpacking and loading device and facilitating the automated recycling of the packaging box 01 and battery boxes 02.

[0113] like Figure 3 As shown, the unpacking and loading device also includes a third platform 9, which includes a third base 91, a fourth base 92, a third rotating wheel 93, a fourth rotating wheel 94, and a second conveyor belt 95. The third base 91 and the fourth base 92 are arranged opposite each other along the length direction of the second conveyor belt 95. Taking the length direction of the second conveyor belt 95 as parallel to the width direction of the first conveyor belt 15 as an example, that is, the length direction of the second conveyor belt 95 is parallel to the width direction Y of the operating platform 1. The third rotating wheel 93 is rotatably mounted on the third base 91, and the fourth rotating wheel 94 is rotatably mounted on the fourth base 92. The second conveyor belt 95 is wound around the third rotating wheel 93 and the fourth rotating wheel 94. The third rotating wheel 93 and the fourth rotating wheel 94 can drive the second conveyor belt 95 to rotate along the length direction of the second conveyor belt 95. The second conveyor belt 95 is used to move the battery cell 03 to the next process.

[0114] After the third platform 9 is set up, the second feeding device 6 places the battery cell 03 on the third platform 9. The second conveyor belt 95 of the third platform 9 can drive the battery cell 03 to move to the next process, reducing the movement distance of the second feeding device 6 and thus simplifying the structure of the second feeding device 6.

[0115] Based on the unpacking and feeding device in any of the above embodiments, a second aspect of this application provides a method for unpacking and feeding battery cells, the method comprising:

[0116] Place the packaging box 01 on the operating platform 1, with the box body abutting against the operating platform 1. Along the height direction Z of the unpacking and feeding device, close the box lid on the side of the box body away from the operating platform 1.

[0117] The packaging box 01 is moved to the separation device 2. Along the height direction Z of the unpacking and feeding device, at least a part of the separation device 2 moves toward the packaging box 01 to break the sealing tape.

[0118] Move the packaging box 01 to the flipping device 3. The flipping device 3 flips the packaging box 01 at a preset angle so that the box lid falls off the box body.

[0119] The packaging box 01 is moved to the first feeding device 4, and at least a part of the first feeding device 4 extends into the box to clamp the battery box 02.

[0120] The first feeding device 4 places the battery box 02 on the operating platform 1. Along the height direction Z of the unpacking and feeding device, the opening of the battery box 02 is located on the side of the battery box 02 away from the operating platform 1.

[0121] The battery box 02 is moved to the film breaking device 5. Along the height direction Z of the unpacking and feeding device, at least a part of the film breaking device 5 moves toward the direction closer to the battery box 02 to break the sealing film 04.

[0122] The battery box 02 is moved to the second feeding device 6, and the second feeding device 6 moves the battery cell 03 to the next process.

[0123] The unpacking and loading device can automatically unpack the packaging box 01 and battery box 02, and also automatically load the battery cells 03. This simplifies the unpacking and loading operation of the battery cells 03, thereby reducing the labor cost of unpacking and loading the battery cells 03. At the same time, it helps to shorten the unpacking and loading cycle of the battery cells 03 and improve the unpacking and loading efficiency. In addition, it reduces the risk of damaging the battery cells 03 during manual unpacking and loading, thereby improving the unpacking yield of the battery cells 03. The flipping device 3 is set so that the opening of the packaging box 01 can face the first loading device 4, thereby simplifying the operation of the first loading device 4 to remove the battery box 02 from the packaging box 01. This simplifies the structure of the first loading device 4 and shortens the time for the first loading device 4 to remove the battery box 02 from the packaging box 01, thereby further shortening the unpacking and loading cycle of the battery cells 03.

[0124] like Figure 3 As shown, when the operating platform 1 includes at least a first platform 16 and a second platform 17, the step of placing the packaging box 01 on the operating platform 1 includes:

[0125] Place the packaging box 01 on the first platform 16;

[0126] The steps of the first feeding device 4 placing the battery box 02 on the operating platform 1 include:

[0128] like Figure 3 As shown, when the unpacking and loading device also includes a first storage box and a second storage box 8, after the step of placing the packaging box 01 on the first platform 16, along the length direction of the first platform 16, that is, along the length direction X of the first conveyor belt 15 of the first platform 16, the first platform 16 drives the packaging box 01 to move to the separation device 2 and / or the flipping device 3 and / or the first loading device 4; after the step of the first loading device 4 placing the battery box 02 on the second platform 17, along the length direction of the second platform 17, that is, along the length direction X of the first conveyor belt 15 of the second platform 17, the second platform 17 drives the battery box 02 to move to the film cutting device 5 and / or the second loading device 6.

[0129] When the number of battery boxes 02 inside packaging box 01 is 0, the unpacking and loading method for the battery cells includes:

[0130] Along the length of the first platform 16, the first platform 16 moves the packaging box 01 toward the first storage box so that the packaging box 01 enters the first storage box;

[0131] When the number of battery cells 03 in battery box 02 is 0, the unpacking and loading method for the battery cells includes:

[0132] Along the length of the second platform 17, the second platform 17 drives the battery box 02 to move closer to the second storage box 8, so that the battery box 02 enters the second storage box 8.

[0133] like Figure 3 As shown, when the unpacking and loading device also includes a third platform 9, the step of the second loading device 6 moving the battery cell 03 to the next process includes:

[0134] The second feeding device 6 moves the battery cell 03 onto the third platform 9;

[0135] Along the length direction of the third platform 9, that is, along the length direction of the second conveyor belt 95, for example, along the width direction Y of the first conveyor belt 15, the third platform 9 drives the battery cell 03 to move to the next process.

[0136] like Figure 3 As shown, when the unpacking and loading device also includes a position detector 7 and a control system, the unpacking and loading method for the solar cells includes:

[0137] Position detector 7 detects the position of battery cell 03 on operating platform 1 and transmits the detection result to control system;

[0138] The control system controls at least one of the following devices to start or stop working based on the received data: the separation device 2, the flipping device 3, the first feeding device 4, the film cutting device 5, and the second feeding device 6.

[0139] In summary, in one embodiment, the method for unpacking and loading battery cells provided in this application is as follows:

[0140] like Figure 3 As shown, the packaging box 01 is placed on the first platform 16. Along the height direction Z of the unpacking and feeding device, the box cover is located on the side of the box body away from the first platform 16. The first conveyor belt 15 on the first platform 16 drives the packaging box 01 to move towards the separation device 2. The packaging box 01 moves to the position sensor near the separation device 2. The position sensor transmits the position information of the packaging box 01 to the control system.

[0141] The control system determines that the packaging box 01 has moved to the bottom of the separation device 2 based on the received data. The control system then controls the separation device 2 to work, and the separation component 22 moves toward the packaging box 01 to cut the sealing tape.

[0142] The packaging box 01 moves toward the flipping device 3 under the drive of the first conveyor belt 15 on the first platform 16. The packaging box 01 moves to the position sensor near the flipping device 3, and the position sensor transmits the position information of the packaging box 01 to the control system.

[0143] The control system determines that the packaging box 01 has moved to the flipping device 3 based on the received data. The control system controls the flipping device 3 to work. The flipping device 3 flips the packaging box 01 by a preset angle along the direction of movement of the packaging box 01, that is, along the length direction X of the first conveyor belt 15, so that the opening of the packaging box 01 faces the first feeding device 4. During the flipping process of the packaging box 01, the lid falls off the box body, and the battery box 02 inside the packaging box 01 is exposed.

[0144] The packaging box 01 moves toward the first feeding device 4 under the drive of the first conveyor belt 15 on the first platform 16. When the packaging box 01 moves to the position sensor near the first feeding device 4, the position sensor transmits the position information of the packaging box 01 to the control system.

[0145] The control system determines that the packaging box 01 has moved to the first feeding device 4 based on the received data. The control system controls the first feeding device 4 to work, and at least part of the second gripper 43 extends into the packaging box 01 and clamps the battery box 02.

[0146] The second cantilever 42 controls the second gripper 43 to move away from the packaging box 01;

[0147] The second gripper 43 places the battery box 02 on the second platform 17. The battery box 02 moves toward the film cutting device 5 under the drive of the first conveyor belt 15 on the second platform 17. When the battery box 02 moves to the position sensor near the film cutting device 5, the position sensor transmits the position information of the packaging box 01 to the control system.

[0148] The control system determines that the battery box 02 has moved to below the film cutting device 5 based on the received data. The control system then controls the film cutting device 5 to work and cuts the encapsulation film 04.

[0149] Driven by the first conveyor belt 15 on the second platform 17, the battery box 02 moves toward the second feeding device 6. When the battery box 02 moves to the position sensor near the second feeding device 6, the position sensor transmits the position information of the packaging box 01 to the control system.

[0150] The control system determines that the battery box 02 has moved to the second feeding device 6 based on the received data. The control system controls the second feeding device 6 to work. At least part of the feeding component 63 of the second feeding device 6 extends into the battery box 02 and clamps the battery cell 03.

[0151] The third cantilever 62 drives the loading component 63 to move away from the battery box 02;

[0152] The feeding component 63 places the battery cell 03 onto the third platform 9. The battery cell 03 moves to the next process under the drive of the second transmission belt on the third platform 9, so as to realize the automatic feeding of the battery cell 03.

[0153] The above description is merely a preferred embodiment of this application and is not intended to limit this application. Various modifications and variations can be made to this application by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this application should be included within the protection scope of this application.
