After the film on the sheet is peeled off, the attachment of the sheet to the predetermined surface of the battery cell is finally completed.

[0047] Furthermore, based on the aforementioned guide funnel design, the film can be collected and transferred, reducing the probability of the film falling outside the collection bucket. At the same time, it can be used in conjunction with the valve assembly to transform the guide funnel into a temporary film storage device when the collection bucket needs to be cleaned, without affecting the operation of the film tearing device.

[0085] Some embodiments of this application are described below with reference to the accompanying drawings. Those skilled in the art should understand that these embodiments are merely illustrative of the technical principles of this application and are not intended to limit the scope of protection of this application.

[0086] Based on this, this application provides a battery cell bonding system. By setting up a wafer transfer device, the wafer can pass through a film-removing station before moving from the loading station to the bonding station, and the film is removed by the film-removing device. The wafer transfer device connects the wafer loading device, the film-removing device, and the battery cell conveying device into a complete production line, making the matching action between the battery cell and the wafer smoother, thereby significantly improving the bonding efficiency of the entire battery cell bonding system.

[0087] The present application will be described in detail below through specific embodiments.

[0088] Reference Figures 1 to 26 As shown, this embodiment provides a battery cell adhesive bonding system, which includes: a wafer loading device 1, a wafer transfer device 2, a film peeling device 3, and a battery cell conveying device 4; the wafer loading device 1 is configured to carry and transport a storage rack 16 containing wafers 17 and transport the wafers 17 in the storage rack 16 to the loading station 291; the wafer transfer device 2 is configured to pick up the wafers 17 at the loading station 291 and transfer the wafers 17 sequentially. The film is removed at the film removal station 292 and the chip bonding station 294, and at the chip bonding station 294, the film-removed sheet 17 is bonded to a predetermined surface of the cell 6; the film removal device 3 is located at the film removal station 292 and is configured to remove the film from the sheet 17 that has moved to the film removal station 292; the cell conveying device 4 is configured to convey the cell 6 to be bonded to the chip bonding station 294 and to convey the cell 6 with the sheet 17 bonded at the chip bonding station 294 away.

[0089] Based on the above-mentioned cell bonding system, the chip transfer device 2 enables the chip 17 to pass through the film removal station 292 before moving from the loading station 291 to the bonding station 294, and the film removal device 3 removes the film. The chip transfer device 2 connects the chip loading device 1, the film removal device 3 and the cell conveying device 4 into a complete production line, making the matching action of the cell 6 and the chip 17 smoother, thereby significantly improving the bonding efficiency of the entire cell bonding system.

[0090] Continue to refer to Figures 5 to 12 As shown, in some embodiments, the sheet feeding device 1 includes: a first conveying assembly 111, a second conveying assembly 112, and a transfer assembly. The first conveying assembly 111 is used to convey the storage rack 16 containing the sheet 17 from the inlet end along a first direction to the first station 181. The transfer assembly is used to transfer the storage rack 16 located at the first station 181 along a second direction to the second station 182. The second conveying assembly 112 is used to convey the storage rack 16 located at the second station 182 along a third direction to the feeding station 291 to supply the sheet 17. The second conveying assembly 112 is also used to convey the empty storage rack 16 located at the feeding station 291 from the feeding station 291 along a third direction to the outlet end. The first direction is opposite to the third direction, and both the first direction and the third direction are perpendicular to the second direction. The inlet end and the first station 181 are respectively located at both ends of the first conveying assembly 111, and the outlet end and the second station 182 are respectively located at both ends of the second conveying assembly 112.

[0091] Furthermore, based on the aforementioned sheet loading device 1, the first conveying component 111 and the second conveying component 112, which are arranged in parallel and transmit in opposite directions, can complete the loading of a fully loaded storage rack 16 and the unloading of an empty storage rack 16 on the same side of both the first conveying component 111 and the second conveying component 112, effectively reducing the operating cost of the sheet loading device 1. Moreover, the first conveying component 111 and the second conveying component 112 can also control the feeding of a fully loaded storage rack 16 and the unloading of an empty storage rack 16, thereby improving the transport efficiency of the storage rack 16 on the sheet loading device 1. The first station 181 and the second station 182 are intermediate stations. Through the setting of the transfer component, the transfer of the storage rack 16 from the first station 181 to the second station 182 can be completed, thereby forming a continuous U-shaped transport track with the first conveying component 111 and the second conveying component 112.

[0092] Optionally, both the first and third directions can be horizontal to ensure that the fully loaded or empty storage rack 16 can smoothly transport the film sheet 17 on the first conveying assembly 111 and the second conveying assembly 112. The second direction can be horizontal, thus forming a U-shaped transport track on the horizontal plane by the first conveying assembly 111, the transfer assembly, and the second conveying assembly 112. Alternatively, the second direction can be vertical, thus forming a U-shaped transport track on the vertical plane by the first conveying assembly 111, the transfer assembly, and the second conveying assembly 112. In other words, the second conveying assembly 112 can be located directly above the first conveying assembly 111. When the storage rack is fully loaded... After the material rack 16 moves to the first station 181, the transfer component lifts the material rack 16 of the first station 181 to the second station 182. At this time, the second conveying component 112 is located above the first conveying component 111, which can prevent the first conveying component 111 from blocking the loading station 291 and affecting the loading of the film sheet 17 at the loading station 291. Furthermore, the second conveying component 112 can also be located diagonally above or diagonally below the first conveying component 111. At this time, the second direction is an inclined direction at a certain angle to the vertical direction. The second direction can be perpendicular to the first direction and the third direction, or it can form an acute angle or an obtuse angle with the first direction and the third direction.

[0093] In some embodiments, the first conveying component 111 and the second conveying component 112 may be a drive belt or other conveying structure.

[0094] Optionally, the transfer assembly 113 includes a transfer member 1131 and a transfer drive member 1132. The transfer member 1131 is installed on the drive end of the transfer drive member 1132. The transfer drive member 1132 drives the transfer member 1131 to reciprocate in a second direction, thereby pushing the storage rack 16 at the first station 181 to the second station 182. Specifically, the transfer member 1131 can be a plate-like structure that pushes the side of the storage rack 16 in the horizontal direction, thereby realizing the movement of the storage rack 16 along the horizontal second direction. Alternatively, the transfer member 1131 can support the bottom of the storage rack 16 in the vertical direction, thereby realizing the movement of the storage rack 16 along the vertical or inclined second direction. The transfer assembly 113 also includes a transfer track disposed between the first station 181 and the second station 182, which extends along the second direction.

[0095] Furthermore, the transfer member 1131 can also be a gripper, suction cup, or other connection structure that can easily connect to or disconnect from the storage rack 16. The transfer drive member 1132 can be a linear motor, cylinder, electric cylinder, or other drive structure that can drive the transfer member 1131 to reciprocate in the second direction. The transfer drive member 1132 can also include a transmission structure consisting of a motor and a transmission belt extending in the second direction, as long as it can realize the reciprocating motion of the transfer member 1131 in the second direction.

[0096] The transfer assembly 113 also includes a first lifting member 11331 and a second lifting member 11332. The first lifting member 11331 and the second lifting member 11332 are respectively arranged at the first station 181 and the second station 182. The first lifting member 11331 can rise to a set height in the vertical direction so that the storage rack 16 located at the first station 181 is separated from the first conveying assembly 111. The second lifting member 11332 can rise in the vertical direction to a position flush with the first lifting member 11331.

[0097] By setting the first lifting member 11331, when the storage rack 16 is transferred from the first station 181 to the second station 182, the bottom of the storage rack 16 can be separated from the first conveying component 111, avoiding interference between the storage rack 16 and the first conveying component 111 and the second conveying component 112. After the storage rack 16 moves above the second station 182, the second lifting member 11332 can more smoothly receive the storage rack 16 transferred from the first station 181 at the same height. After receiving the storage rack 16, the second lifting member 11332 drives the storage rack 16 to move down until the storage rack 16 lands on the second conveying component 112, so that it can be transported by the second conveying component 112.

[0098] In some further embodiments, the top of the first lifting member 11331 and / or the second lifting member 11332 is provided with a rolling member 1134. The first lifting member 11331 and / or the second lifting member 11332 roll in contact with the bottom of the storage rack 16 through the rolling member 1134. The rolling member 1134 can be a roller, ball, or Mecanum wheel, etc., thereby enabling the transfer member 1131 to push the storage rack 16 on the first lifting member 11331 onto the second lifting member 11332. At the same time, reducing the friction between the bottom of the storage rack 16 and the first lifting member 11331 and / or the second lifting member 11332 can also improve the stability of the storage rack 16 when it moves; specifically, when the rolling member 1134 is a Mecanum wheel, it can not only provide reliable and stable support for the bottom of the storage rack 16, but also achieve rolling friction between the storage rack 16 and the first lifting member 11331 and / or the second lifting member 11332 when the storage rack 16 moves in the first direction, the second direction or the third direction.

[0099] The transfer assembly 113 also includes a transfer track disposed between the first lifting member 11331 and the second lifting member 11332. The transfer track extends along the second direction and includes a transfer plane 1136. The transfer plane 1136 is flush with the first lifting member 11331 after it has risen to a set height. It should be noted that when the storage rack 16 moves from the first lifting member 11331 to the second lifting member 11332, the storage rack 16 first disengages from the first lifting member 11331, then moves to the transfer plane 1136 of the transfer track, and then moves to the second lifting member 11332. Specifically, the bottom of the storage rack 16 can simultaneously contact two or three of the first lifting member 11331, the transfer track, and the second lifting member 11332.

[0100] By setting up the transfer track, the gap between the first lifting member 11331 and the second lifting member 11332 can be filled, so that the storage rack 16 can always be reliably supported during the process of moving from the first station 181 to the second station 182.

[0101] In some embodiments, the transfer track further includes two sets of first track baffles 11351 arranged along a first direction. The two sets of first track baffles 11351 are spaced apart by a predetermined distance, which is not less than the length of the storage rack 16 in the first direction. The two sets of first track baffles 11351 form a transfer path for the storage rack 16 to move from the first station 181 to the second station 182. Specifically, the two first track baffles 11351 extend along a second direction and can limit the storage rack 16 in the first direction. Furthermore, the transfer path formed between the two first track baffles 11351 can provide a stable limit for the storage rack 16, enabling the storage rack 16 to move along a predetermined route.

[0102] Furthermore, one of the first track baffles 11351 is located between the first station 181 and the second station 182, and its length is no greater than the length of the gap between the first station 181 and the second station 182 in the second direction. The other first track baffle 11351 extends from the end of the first station 181 away from the second station 182 to the end of the second station 182 away from the first station 181, and its length is equivalent to the total length of the first station 181, the second station 182, and the gap between the first station 181 and the second station 182 in the second direction. That is, the longer first track baffle 11351 can limit the storage rack 16 located at the first station 181 and the second station 182 in the first direction.

[0103] In a further embodiment, the transfer track also includes a second track baffle 11352, which extends along a first direction or a third direction. The second track baffle 11352 is disposed on the side of the second station 182 away from the first station 181 and / or on the side of the first station 181 away from the second station 182, thereby further improving the stability of the storage rack 16 when it is located at the first station 181 and / or the second station 182, and preventing the storage rack 16 from falling from the first station 181 or the second station 182 along the second direction outside the first conveying assembly 111 or the second conveying assembly 112.

[0104] Specifically, the second track baffle 11352 can be a separate plate structure, or it can be formed by bending one of the first track baffles 11351 by 90 degrees.

[0105] In some further embodiments, the sheet feeding device 1 also includes a positioning sensor 13 and a lifting mechanism 12 disposed at the feeding station 291. The storage rack 16 includes a bracket for limiting the sheet 17 and a support member 1611 for supporting the sheet 17. The support member 1611 is configured to move up and down within the bracket under the drive of the lifting mechanism 12. The positioning sensor 13 is disposed above the feeding station 291 and is used to detect whether the uppermost sheet 17 in the storage rack 16 located at the feeding station 291 has risen into position.

[0106] The positioning sensor 13 can be a pair of photoelectric sensors with the transmitting end and the receiving end located on the same horizontal plane and respectively located on both sides of the loading station 291. When the uppermost piece 17 rises to the position, the uppermost piece 17 can block the light transmission between the transmitting end and the receiving end of the positioning sensor 13, so that the positioning sensor 13 detects that the uppermost piece 17 has moved to the position. The positioning sensor 13 sends a signal to the lifting mechanism 12 to stop it from continuing to lift.

[0107] In some embodiments, the lifting mechanism 12 includes a lifting drive 121, a first telescopic drive 122, and a lifting member 123. The first telescopic drive 122 is connected to the lifting drive 121 and is disposed on the side of the loading station 291. The lifting member 123 is installed at the driving end of the first telescopic drive 122 or the driving end of the lifting drive 121. The first telescopic drive 122 is used to drive the lifting member 123 to move closer to or further away from the storage rack 16. The lifting drive 121 is used to drive the lifting member 123 to reciprocate in the vertical direction. The lifting member 123 is used to lift the support member 1611 located at the loading station 291 upward.

[0108] Specifically, the lifting member 123 can be a plate-like structure, which can stably lift the plate-like film sheet 17. The lifting drive member 121 and the first telescopic drive member 122 can be one or more of the following structures: linear motor, cylinder, electric cylinder, etc.

[0109] It should be noted that there is a gap in the vertical direction between every two adjacent sheet bodies 17 that is greater than the thickness of the lifting member 123, so that the lifting member 123 can be inserted between any two adjacent sheet bodies 17. Furthermore, when lifting the sheet body 17 upward, the lifting member 123 can be inserted under the bottom sheet body 17 and then moved upward a certain distance each time, so that the top sheet body 17 can rise into place and complete the loading. Alternatively, the lifting member 123 can only lift the top sheet body 17 into place each time to complete the loading. Or, the lifting member 123 can lift two or more sheet bodies 17 each time until all the sheet bodies 17 above the lifting member 123 have been loaded in sequence, and then move downward to under two or more sheet bodies 17. The specific choice can be made according to the load-bearing capacity of the lifting member 123 and other requirements.

[0110] In some embodiments, the storage rack 16 includes at least two sheet receiving spaces 161 arranged side by side, each sheet receiving space 161 having a support member 1611 configured to support a sheet 17; the sheet loading device 1 also includes a rotating mechanism 14, which is configured to drive the storage rack 16 located at the loading station 291 to rotate horizontally by a predetermined angle to control at least two sheet receiving spaces 161 to move sequentially to the loading position. The sheet receiving space 161 moving to the loading position means that the projection of the sheet receiving space 161 in the vertical direction coincides with the projection of the sheet picking position. After the sheet 17 in the sheet receiving space 161 is lifted into position, the loading work can be completed. The rotating mechanism 14 enables one storage rack 16 to transport multiple rows of sheets 17 at the same time, thereby significantly improving the loading efficiency of the sheet 17. This loading method not only improves the loading efficiency but also controls the overall height of the storage rack 16, improving the stability of the storage rack 16 during transportation.

[0111] In some embodiments, the rotating mechanism 14 includes a rotating drive 141 and a lifting drive 142. The fixed end of the rotating drive 141 is fixedly connected to the driving end of the lifting drive 142. The movable end of the rotating drive 141 abuts against the storage rack 16 located at the loading station 291. The lifting drive 142 is configured to drive the rotating drive 141 to reciprocate in the vertical direction, and the rotating drive 141 is configured to drive the storage rack 16 to rotate in the horizontal plane. Through the arrangement of the lifting drive 142, it is possible to... When the storage rack 16 of the drive loading station 291 rotates, the storage rack 16 is disengaged from the second conveying component 112, thereby reducing the interference caused by the second conveying component 112 on the rotation of the storage rack 16. The lifting drive component 142 can lift the storage rack 16 before it needs to be driven to rotate, and lower the storage rack 16 onto the second conveying component 112 before the lifting mechanism 12 lifts the sheet 17 on the storage rack 16, thereby improving the stability of the storage rack 16 when the lifting mechanism 12 lifts the sheet 17.

[0112] Optionally, the rotary drive component 141 can be a rotary cylinder, motor, or other structure, and the lifting drive component 142 can be a linear motor, cylinder, electric cylinder, or other structure.

[0113] Furthermore, the sheet feeding device 1 also includes a blocking mechanism 15. A third station 183 is provided between the feeding end and the first station 181. At least one of the first station 181, the second station 182, the third station 183, and the feeding station 291 is provided with a blocking mechanism 15. The blocking mechanism 15 can be raised and lowered in the vertical direction to block and limit the storage rack 16 above. The third station 183 can be a position opposite to the feeding station 291 in the second direction, that is, the storage rack 16 is at a position where the first station 181 moves along the second direction by one dimension. The third station 183 limits the storage rack 16, which can prevent the storage rack 16 that has not yet been transported from the first station 181 to the second station 182 from colliding with the storage rack 16 moving from the third station 183 to the first station 181. It should be understood that there can be at most one storage rack 16 between the first station 181 and the second station 182. That is to say, before the storage rack 16 of the second station 182 is transported to the loading station 291, no storage rack 16 will be transported from the third station 183 to the first station 181, and the first station 181 is empty at this time.

[0114] In some embodiments, the outer ring of the storage rack 16 is provided with an outer retaining ring 162. The outer retaining ring 162 of the storage rack 16 located at the first station 181 can abut against the outer retaining ring 162 of the storage rack 16 located at the third station 183, and the outer retaining ring 162 of the storage rack 16 located at the second station 182 can abut against the outer retaining ring 162 of the storage rack 16 located at the loading station 291. This ensures that the storage rack 16 can achieve the limiting of two adjacent stations through the outer retaining ring 162. It should be understood that when the storage rack 16 is located at the loading station 291, its outer retaining ring 162 is coaxially arranged with the output shaft of the rotary drive 141. This ensures that the storage rack 16 located at the loading station 291 will not rub against the surrounding structure when rotating, thus affecting the stability of the storage rack 16 when rotating.

[0115] Optionally, the blocking mechanism 15 may include a linear motor, electric cylinder, pneumatic cylinder, or other structure capable of extending and retracting in the vertical direction. By setting up the blocking mechanism 15, the blocking mechanism 15 can block and limit the storage rack 16 above it or moving toward it, preventing it from continuing to move and colliding with the storage rack 16 that has already passed the blocking mechanism 15.

[0116] Continue to refer to Figures 13 to 21 As shown, the sheet transfer device 2 includes: a fixed frame 21, a rotating frame 22, a rotating drive 23, and at least three sheet fixing assemblies 24 arranged circumferentially on the rotating frame 22; the rotating frame 22 is rotatably mounted on the fixed frame 21 via a first rotating shaft, and the drive end of the rotating drive 23 is connected to the rotating frame 22 for transmission. The rotating drive 23 is configured to drive the rotating frame 22 to rotate, thereby driving all sheet fixing assemblies 24 to rotate around the first rotating shaft; there is a set angle between two adjacent sheet fixing assemblies 24. When the rotating frame 22 rotates around the first rotating shaft at a set angle, at least three sheet fixing assemblies 24 correspond one-to-one with the loading station 291, the film peeling station 292, and the sheet bonding station 294, respectively; wherein, there can be four sheet fixing assemblies 24. When there are four wafer fixing components 24, they can be spaced 90 degrees apart. When there are three wafer fixing components 24, they can be spaced 120 degrees apart. The four wafer fixing components 24 can be connected to the loading station 291, the film peeling station 292, the aligning station 293, and the bonding station 294, respectively. The four stations can be arranged sequentially along the rotation direction of the wafer fixing components 24 (clockwise or counterclockwise). This allows the wafer fixing components 24 to first move to the loading station 291 and connect, fix, or release a wafer 17. Then, the protective film on the wafer 17 is peeled off at the film peeling station 292. Next, before reaching the bonding station 294, the wafer 17's position and orientation are adjusted at the aligning station 293. Finally, it is bonded and fixed to the predetermined surface of the battery cell 6 at the bonding station 294. Of course, the number of stations can be increased or decreased according to the actual working conditions.

[0117] Furthermore, based on the wafer transfer device 2, with at least two wafer fixing components 24 arranged on the rotating frame 22, after the rotating frame 22 rotates a certain angle, one wafer fixing component 24 completes the wafer picking action at the loading station 291. After the rotating frame 22 rotates another certain angle, before the previous wafer fixing component 24 moves to the placement station 294, the other wafer fixing component 24 moves to the loading station 291 and completes the wafer picking action, thereby realizing the cyclic action of at least two wafer fixing components 24. That is to say, when the rotating frame 22 rotates once, at least two wafers 17 can be placed, thereby significantly improving the placement efficiency of the entire wafer transfer device 2. Moreover, by completing the wafer picking and placement actions through the rotation action of the rotating frame 22, the conveying path of the wafer 17 can be effectively shortened, and the space occupied by the wafer transfer device 2 can also be reduced.

[0118] The rotating drive component 23 can be a motor or a rotary cylinder, etc. The output end of the rotating drive component 23 can be directly connected to the rotating frame 22 for coaxial transmission, or the output end of the rotating drive component 23 can be connected to the rotating frame 22 for transmission through a gear set. The specific choice can be made according to the specifications of the rotating drive component 23.

[0119] In some embodiments, the sheet fixing assembly 24 includes a connecting frame 241 and a fixing member 242 mounted on the connecting frame 241. The connecting frame 241 is mounted on the rotating frame 22, and the fixing member 242 is configured to fix or release a sheet 17. The fixing member 242 can fix the sheet 17 by clamping, adsorption, bonding, etc., to ensure that the sheet 17 can always maintain relative stability with the fixing member 242 during the rotation of the rotating frame 22. It should be noted that the fixing member 242 should not interfere with the side of the sheet 17 that is covered with film when fixing the sheet 17.

[0120] In some embodiments, the connecting frame 241 is radially slidably disposed on the rotating frame 22 along the first rotating axis, and / or the fixing member 242 is radially slidably disposed on the connecting frame 241 along the first rotating axis; that is, by sliding the connecting frame 241 and / or the fixing member 242, the fixing member 242 can extend in a direction away from the first rotating axis to pick up the sheet and the fixing member 242 can drive the sheet body 17 to extend in a direction away from the first rotating axis to apply the sheet. It can also drive the fixing member 242 to extend the sheet body 17 in a direction away from the first rotating axis to complete the actions of tearing the film and straightening the sheet body 17.

[0121] Furthermore, the fixing component 242 is a suction cup, which is connected to the negative pressure device through an air tube. The fixing frame 21 is provided with a slip ring 25, and the air tube is connected to the negative pressure device through the slip ring 25. Specifically, the air tube is connected to the rotor of the slip ring 25, and the negative pressure device is connected to the stator of the slip ring 25. This ensures that when the fixing component 242 drives the air tube to rotate together, the air tube is not easy to get tangled or knotted, while maintaining the connection between each fixing component 242 and the negative pressure device.

[0122] In some embodiments, the sheet transfer device 2 further includes a second telescopic drive member 26, the fixed end of the second telescopic drive member 26 is fixedly connected to the fixed frame 21, the driving end of the second telescopic drive member 26 is connected to the connecting frame 241 or the fixed member 242, and the second telescopic drive member 26 is configured to drive the connecting frame 241 or the fixed member 242 to slide radially along the first rotating shaft.

[0123] Optionally, the second telescopic drive component 26 can be a linear motor, electric cylinder, pneumatic cylinder, or other structure. By setting the second telescopic drive component 26, it can also actively drive the corresponding connecting frame 241 or fixing component 242 to slide. Specifically, the second telescopic drive component 26 can be set one-to-one with the sheet fixing component 24. The second telescopic drive component 26 can also be set at one or two or more set stations, thereby ensuring that when the sheet fixing component 24 is transported to the set station, it can slide radially along the first rotating shaft to realize sheet picking, sheet application, film peeling, or straightening.

[0124] In some embodiments, at least two set stations include a loading station 291 and a bonding station 294. The number of second telescopic drive members 26 is two sets, and the two sets of second telescopic drive members 26 are respectively set at the loading station 291 and the bonding station 294. They are used to drive the fixing member 242 or the connecting frame 241 located at the loading station 291 to slide radially along the first rotating axis to control the fixing member 242 to pick up the chip, and to drive the fixing member 242 or the connecting frame 241 located at the bonding station 294 to slide radially along the first rotating axis to control the fixing member 242 to attach the chip 17 to the predetermined surface of the cell 6.

[0125] Furthermore, the sheet transfer device 2 also includes a fixed connecting frame 27, and the fixed end of the second telescopic drive member 26 is fixedly mounted on the fixed frame 21 through the fixed connecting frame 27. The second telescopic drive member 26 can be set only at the loading station 291 and the sheet bonding station 294. That is, when the sheet 17 is transported to the film peeling station 292 and the straightening station 293, it is not necessary to push the sheet 17 radially along the first rotating shaft. The two second telescopic drive members 26 can be fixedly mounted on the same fixed connecting frame 27. The setting of the fixed connecting frame 27 can further improve the stability of the two second telescopic drive members 26 and improve the accuracy of their operation.

[0126] In some embodiments, the fixing frame 21 is provided with an annular track 281, and each sheet fixing component 24 is slidably engaged with the annular track 281 via a track slider 282. Preferably, the annular track 281 is a circular ring coaxial with the first rotating shaft, ensuring smooth sliding of all sheet fixing components 24 on the annular track 281 via the track slider 282. Specifically, the track slider 282 can be a fan-shaped slider, in which case the inner wall of the track slider 282 slidably engages with the inner wall of the annular track 281, and the outer wall of the track slider 282 slidably engages with the outer wall of the annular track 281. The track slider 282 can also be a cylindrical slider, thereby reducing friction between it and the annular track 281 and making the sliding smoother.

[0127] In some embodiments, the annular track 281 has notches at at least two set positions. The track slider 282 can slide along the notches in the radial direction of the first rotating shaft. That is, when the sheet fixing assembly 24 and the track slider 282 slide to the notch position, they can disengage from the annular track 281 through the notch under the drive of the second telescopic drive member 26 and move radially along the first rotating shaft. This enables the second telescopic drive member 26 to drive the connecting frame 241 or the fixing member 242 to move radially along the first rotating shaft at the set position. And / or, the fixing frame 21 has sliding plates 283 at at least two set positions. The sliding plates 283 are slidably disposed on the fixing frame 21 in the radial direction of the first rotating shaft. At least part of the annular track 281 is formed on the sliding plates 283. That is, the sliding plates 283 have track grooves for the track slider 282 to slide on. The track grooves can be connected to the fixing frame 21. The annular track 281 on the frame 21 is assembled to form a complete annular track groove. When the plate fixing assembly 24 and the track slider 282 slide to the position of the sliding plate 283, the track slider 282 abuts against the sliding plate 283. At this time, the second telescopic drive member 26 drives the connecting frame 241 or the fixing member 242 to move radially along the first rotating axis, thereby driving the sliding plate 283 to move radially along the first rotating axis. Finally, the sliding plate 283 will drive the track slider 282 to move synchronously radially along the first rotating axis. At this time, the track groove on the sliding plate 283 will disengage from the annular track 281 on the fixing frame 21. When the second telescopic drive member 26 drives the connecting frame 241 or the fixing member 242 to reset, the sliding plate 283 and the track slider 282 are reset under the drive of the second telescopic drive member 26, and the track groove on them re-overlaps with the annular track 281 on the fixing frame 21 to form an annular structure.

[0128] Furthermore, the sliding plate 283 may have two radial sides parallel to the first axis of rotation. The sliding plate 283 slides with the fixing frame 21 through the two side plates, thereby improving the stability and reliability of the sliding plate 283 when sliding radially along the first axis of rotation.

[0129] The number of sheet fixing components 24 and the number of setting stations are both four. Each pair of adjacent sheet fixing components 24 is spaced 90 degrees apart, and each pair of adjacent setting stations is also spaced 90 degrees apart. The four setting stations can be respectively a loading station 291, a film peeling station 292, a sizing station 293, and a sheet bonding station 294. The four stations can be arranged sequentially along the rotation direction of the sheet fixing components 24 (clockwise or counterclockwise), so that the sheet fixing components 24 first move to the loading station 291 and are then connected and fixed. A wafer 17 is first removed from the loading station 291 and then passes through the straightening station 293 to have its film removed. Before reaching the bonding station 294, the wafer 17's position and orientation are adjusted. Finally, it is bonded to the predetermined surface of the battery cell 6 at the bonding station 294. It should be understood that after the wafer fixing assembly 24 picks up a wafer 17 from the loading station 291, it rotates 90 degrees to the film removal station 292 for film removal. At this time, the second wafer fixing assembly 24 moves to the loading station 291 and begins picking up wafers. The sheet fixing assembly 24 at the film station 292 continues to rotate 90 degrees to the alignment station 293 to adjust the relative position between the sheet 17 and the sheet fixing assembly 24. At this time, the second sheet fixing assembly 24 moves to the film tearing station 292 to tear the film, and the third sheet fixing assembly 24 moves to the loading station 291 to start picking up the sheet. The first sheet fixing assembly 24 continues to rotate 90 degrees to the bonding station 294 and attaches the sheet 17 to the predetermined surface of the cell 6. The second sheet fixing assembly 24 rotates to the alignment station 293 to adjust the relative position between the sheet 17 and the sheet fixing assembly 24. The adjustment station 293 adjusts the relative position between the sheet 17 and the sheet fixing assembly 24. The third sheet fixing assembly 24 rotates to the film peeling station 292 to peel the film. Meanwhile, the fourth sheet fixing assembly 24 moves to the loading station 291 and begins to pick up the sheet. The first sheet fixing assembly 24 continues to rotate 90 degrees and returns to the loading station 291 to pick up the sheet, starting the next cycle. This sheet transfer device 2 can simultaneously enable the four sheet fixing assemblies 24 to continuously cycle, thereby improving the film application efficiency.

[0130] The fastener 242 has a fixing plane for fixing the sheet 17, the fixing plane is perpendicular to the radial direction of the first rotating shaft, wherein two setting stations are arranged in the vertical direction and the other two setting stations are arranged in the horizontal direction, and the uppermost setting station is used to regulate the sheet 17 located on the uppermost fixing plane.

[0131] Continue to refer to Figure 24As shown, the cell bonding system also includes a straightening device 5 configured to straighten the sheet 17 located at the straightening station 293. There are four sheet fixing assemblies 24, spaced 90 degrees apart from each other. The loading station 291, film-peeling station 292, straightening station 293, and bonding station 294 are arranged sequentially along the circumference of the first rotating axis, with each pair of adjacent stations spaced 90 degrees apart. The fixing member 242 has a fixing plane configured to fix the sheet 17, perpendicular to the radial direction of the first rotating axis. Two stations are arranged vertically, and the other two are arranged horizontally. The arrangement is directional, with the straightening station 293 being the uppermost station. At this time, the fixed plane is horizontal. After the sheet body fixing assembly 24 moves the sheet body 17 to the straightening station 293, the fixing of the sheet body 17 by the fixing member 242 can be cancelled. Specifically, this can be achieved by releasing the negative pressure in the suction cup on the fixing member 242 or by separating the grippers. The sheet body 17 can be held on the fixed plane with the support of the fixed plane. Then, the straightening device 5 can straighten the sheet body 17 more easily and reduce the external force on the sheet body 17, thus reducing the probability of damage to the sheet body 17 during straightening.

[0132] Furthermore, the straightening device 5 includes at least three straightening push plates 51 arranged circumferentially along the sheet 17 of the straightening station 293. The straightening push plates 51 extend vertically and have a pushing surface in the horizontal direction for pushing the sheet 17.

[0133] Optionally, the cell conveying device 4 includes a cell transfer mechanism 41, a third conveying assembly 42 configured to convey unfinished cells 6, and a fourth conveying assembly 43 configured to convey finished cells 6. The cell transfer mechanism 41 includes a cell transfer frame 411 and at least two cell fixing members 412 configured to fix the cells 6. The cell transfer frame 411 is configured to drive one of the cell fixing members 412 to reciprocate between the third conveying assembly 42 and the cell mounting station 294 to move the cells 6 on the third conveying assembly 42 to the cell mounting station 294. The cell transfer frame 411 is also configured to drive the other cell fixing member 412 to reciprocate between the fourth conveying assembly 43 and the cell mounting station 294 to move the cells 6 with the attached chip body 17 on the cell mounting station 294 to the fourth conveying assembly 43.

[0134] Optionally, the cell delivery device 4 also includes a buffer rack and a detection mechanism 44 disposed between the placement station 294 and the third delivery assembly 42. The buffer rack has a buffer station configured to hold the cell 6 taken from the third delivery assembly 42 and ready to be delivered to the placement station 294. The placement station 294 and the fourth delivery assembly 43 have a detection station, and the detection mechanism 44 is configured to detect whether the cell 6 located at the detection station meets the placement requirements.

[0135] Optionally, the cell transfer mechanism 41 includes four cell fixing members 412; the cell transfer frame 411 is configured to drive the first cell fixing member 412 along the transport direction of the cell 6 to reciprocate between the third transport assembly 42 and the buffer station, so as to move the cell 6 on the third transport assembly 42 to the buffer station; the cell transfer frame 411 is also configured to drive the second cell fixing member 412 along the transport direction of the cell 6 to reciprocate between the buffer station and the chip mounting station 294, so as to move the cell on the buffer station to the chip mounting station. 6. Move to the chip mounting station 294; the cell transfer frame 411 is also configured to drive the third cell fixing member 412 along the transport direction of the cell 6 to reciprocate between the chip mounting station 294 and the inspection station, so as to move the cell 6 on the chip mounting station 294 to the inspection station; the cell transfer frame 411 is also configured to drive the fourth cell fixing member 412 along the transport direction of the cell 6 to reciprocate between the fourth transport assembly 43 and the inspection station, so as to move the cell 6 on the inspection station to the fourth transport assembly 43.

[0136] In some embodiments, the third conveying component 42 and the fourth conveying component 43 may be a drive belt or other conveying structure.

[0137] In some embodiments, the cell transfer frame 411 drives the four cell fixing members 412 to move synchronously, so that all the cells 6 transferred by the cell transfer frame 411 can achieve stepping motion; wherein, the movement of the four cell fixing members 412 driven by the cell transfer frame 411 can include horizontal movement and vertical movement, so that the surface of the cell 6 does not have relative friction with each station or conveyor belt, thereby reducing the surface wear of the cell 6.

[0138] Continue to refer to Figure 1 , Figure 2 , Figure 3 , Figure 25 and Figure 26 As shown, the cell conveying device 4 also includes a dust removal mechanism 45, which has a dust removal nozzle 451. The dust removal nozzle 451 is positioned toward the predetermined surface of the cell 6 to be bonded to the substrate 17 and is configured to clean the predetermined surface of the cell 6 before the cell transfer frame 411 moves the cell 6 to be bonded to the bonding station 294.

[0139] Furthermore, based on the aforementioned dust removal mechanism 45, gas or plasma can be sprayed onto the predetermined surface of the battery cell 6 using the dust removal nozzle 451 to clean the predetermined surface of the battery cell 6 and ensure the bonding effect between the sheet body 17 and the battery cell 6.

[0140] The dust removal mechanism 45 also has a dust suction port 452. After the dust removal nozzle 451 sprays plasma onto the predetermined surface of the battery cell 6, the dust will be sucked in by the dust suction port 452 to avoid secondary pollution of other structures by the dust.

[0141] Optionally, the battery cell conveying device 4 also includes a battery cell monitoring component 46. The monitoring end of the battery cell monitoring component 46 is located on the side of the dust removal mechanism 45 near the third conveying component 42. The battery cell monitoring component 46 is configured to monitor the moving battery cell 6 to prevent the battery cell 6 from colliding with the dust removal mechanism 45. The battery cell monitoring component 46 can be a through-beam photoelectric sensor component. It determines whether the battery cell 6 has moved to a position that may collide with the dust removal mechanism 45 by the on / off state of the light signal. If the battery cell 6 blocks the transmission of the light signal on the battery cell monitoring component 46, the third conveying component 42 can be stopped to avoid the battery cell 6 colliding with the dust removal mechanism 45.

[0142] Furthermore, based on the aforementioned cell monitoring component 46, the cell 6 and the dust removal mechanism 45 can be protected to prevent the cell 6 from changing position on the third conveying component 42, thereby preventing damage to the cell 6 and the dust removal mechanism 45.

[0143] Continue to refer to Figures 1 to 3 as well as Figure 22 and Figure 23 As shown, the film-tearing device 3 includes a collection bucket 31, a film-tearing translation component 32, and a gripper component 33 corresponding to the film-tearing station 292. The gripper component 33 is installed on the drive end of the film-tearing translation component 32. The film-tearing translation component 32 is configured to drive the gripper component 33 to translate between the film-tearing position and the film-releasing position. The film-tearing position corresponds to the film-tearing station, and the film-releasing position corresponds to the collection bucket 31. The gripper component 33 is configured to tear off the film on the sheet 17 located at the film-tearing station at the film-tearing position. The gripper component 33 is also configured to put the torn film into the collection bucket 31 at the film-releasing position.

[0144] Furthermore, based on the aforementioned film-tearing device 3, the film on the sheet 17 can be quickly torn off, and the film can be collected using the collection bucket 31 to avoid film contamination.

[0145] Optionally, the film-tearing device 3 also includes a guide funnel 34 separately disposed from the collection tank 31. The guide funnel 34 is disposed between the film-laying position and the collection tank 31. The gripper assembly 33 is configured to feed the torn film into the top inlet of the guide funnel 34 at the film-laying position. The bottom outlet of the guide funnel 34 is disposed directly opposite the collection tank 31. A valve assembly 35 is provided on the guide funnel 34. The valve assembly 35 is disposed near the outlet of the guide funnel 34. The valve assembly 35 is configured to open or close the outlet of the guide funnel 34.

[0146] Based on the above-mentioned guide funnel 34, the film can be collected and transferred, reducing the probability of the film falling outside the collection bucket 31. At the same time, it can also work with the valve assembly 35 to make the guide funnel 34 a temporary film storage device when the collection bucket 31 needs to be cleaned, without affecting the operation of the film tearing device 3. The valve assembly 35 can be composed of a valve baffle and a cylinder. The cylinder drives the valve baffle to reciprocate to open and close the guide funnel 34.

[0147] Continue to refer to Figures 1 to 3 As shown, the projection of at least one of the sheet transfer device 2, the film tearing device 3, and the cell conveying device 4 in the vertical direction at least partially overlaps with the projection of the sheet feeding device 1 in the vertical direction.

[0148] Furthermore, based on the arrangement of the sheet transfer device 2, the film peeling device 3, and the cell conveying device 4, the footprint of the entire cell adhesive application system can be reduced.
