[0095] In order to more clearly understand the embodiments of the present application, the following will be combined with Figures 1 to 20 The embodiments of the present application are described in detail.

[0096] As Figures 5 to 18 shown, the present application provides an electric core separation device 1 for separating the electric core 7 from the cup 8, the electric core separation device 1 comprising a holding assembly 11, an ejection assembly 12 and a guide assembly 13. Among them, the holding assembly 11 comprises a first holding piece 111, the first holding piece 111 is used for holding the cup 8; the ejection assembly 12 is movably arranged on the side of the holding assembly 11 close to the first holding piece 111 along the first direction X, the ejection assembly 12 comprises an ejection piece 121 and a protrusion 122, the ejection piece 121 is arranged relative to the first holding piece 111 along the first direction X; the guide assembly 13 is arranged on the side of the ejection assembly 12 close to the protrusion 122 along the second direction Y, the guide assembly 13 is provided with a guide groove 131 extending along the third direction Z, the protrusion 122 is arranged in the guide groove 131, so as to drive the protrusion 122 to move along the first direction X, thereby ejecting the electric core 7 from the cup 8, the first direction X, the second direction Y and the third direction Z are perpendicular to each other.

[0097] The electric core 7 can be a lithium ion battery, a lithium-sulfur battery, a sodium lithium ion battery, a sodium ion battery or a magnesium ion battery, etc. The shape of the electric core 7 can be a cylinder, a flat body, a cuboid or other shapes, etc. The embodiments of the present application do not limit this.

[0098] The cup 8 refers to a component for supporting the battery cell 7. Specifically, the cup 8 is provided with a battery cell accommodating portion for accommodating the battery cell 7, and one end of the battery cell 7 is inserted into the battery cell accommodating portion along the first direction X, so as to realize the support of the cup 8 to the battery cell 7. By inserting the battery cell 7 into the cup 8, on the one hand, the uniform specification and shape of the cup 8 can be utilized to facilitate cooperation with various automatic transportation devices (such as a conveyor belt, a mechanical arm, etc.), so as to realize the rapid and accurate transportation of the battery cell 7 between different stations, and improve the production efficiency; on the other hand, the cup 8 can fix and constrain the battery cell 7, so that the battery cell 7 maintains a relatively stable position and posture in the cup 8, which is convenient for accurate positioning and operation of the battery cell 7, and further ensures the quality and consistency of the battery cell 7 production.

[0099] In some embodiments, the cup 8 is also provided with a guide hole, which penetrates the cup 8 along the first direction X and is connected to the battery cell accommodating portion, so as to ensure that the ejecting assembly 12 can extend into the accommodating portion from the guide hole, thereby ejecting the battery cell 7 from the cup 8.

[0100] The holding assembly 11 refers to a component for holding materials, and the holding assembly 11 includes a first holding piece 111 for holding the cup 8. In some embodiments, the first holding piece 111 can be a mechanical gripper, which realizes the grasping and releasing of materials by driving a plurality of movable claws to open and close. In other embodiments, the first holding piece 111 can also be a suction accessory, which fixes the cup 8 by suction force. It should be noted that at this time, the suction accessory can be a negative pressure device, which generates negative pressure by suctioning negative pressure to the first holding piece 111 to fix the cup 8. When the cup is made of magnetic materials such as iron, the suction device can also be a magnetic device, which generates magnetic force by an electromagnet or a permanent magnet to fix the cup 8.

[0101] The ejecting assembly 12 is a component for ejecting the battery cell 7 from the cup 8. The ejecting assembly 12 is movably arranged on the side of the holding assembly 11 close to the first holding piece 111 along the first direction X, and when the ejecting assembly 12 moves along the first direction X, it can extend into the cup 8 from the side of the cup 8 away from the battery cell 7, thereby ejecting the battery cell 7 from the cup 8.

[0102] Specifically, the ejecting assembly 12 includes an ejecting piece 121 and a protrusion 122. The ejecting piece 121 is arranged relative to the first holding piece 111 along the first direction X, that is, the ejecting piece 121 is arranged corresponding to the cup 8 along the first direction X, so that when the ejecting assembly 12 moves along the first direction X to approach the holding assembly 11, the ejecting piece 121 can extend into the cup 8, thereby ejecting the battery cell 7 from the cup 8.

[0103] In some embodiments, the end of the ejecting piece 121 away from the protrusion 122 can be provided with a buffer portion made of soft materials such as rubber, so as to reduce the damage to the battery cell 7 when the battery cell 7 is ejected.

[0104] The protrusion 122 is arranged at the end of the ejector 121 away from the holding assembly 11, and is arranged in the guide groove 131. The movement of the protrusion 122 in the first direction X can be realized by setting the trajectory of the guide groove 131, so as to push the ejector 121 to move in the first direction X, and then realize the ejecting of the battery cell 7 from the cup 8.

[0105] In some embodiments, the protrusion 122 can also be a roller, that is, the protrusion 122 is a cylindrical member that can rotate along its own axis. In this way, when the protrusion 122 moves along the guide groove 131, it can roll in the guide groove 131. That is, the sliding friction between the protrusion 122 and the guide groove 131 can be converted into rolling friction, reducing the friction between them and improving the service life of the protrusion 122 and the guide groove 131.

[0106] The guide assembly 13 refers to a member for guiding the movement of the protrusion 122. As shown in FIGS. 1, 2 and 11, the guide assembly 13 is provided with a guide groove 131 extending in the third direction Z, and the protrusion 122 is arranged in the guide groove 131. That is, the guide assembly 13 is a planar guide member, which drives the protrusion 122 to move in the third direction Z while driving the ejector 121 to move towards or away from the first holding member 111 in the first direction X. Figure 8 、 10 As shown in FIGS. 1, 2 and 11, the guide assembly 13 is provided with a guide groove 131 extending in the third direction Z, and the protrusion 122 is arranged in the guide groove 131. That is, the guide assembly 13 is a planar guide member, which drives the protrusion 122 to move in the third direction Z while driving the ejector 121 to move towards or away from the first holding member 111 in the first direction X.

[0107] As shown in FIGS. 1, 2 and 11, the guide assembly 13 is provided with a guide groove 131 extending in the third direction Z, and the protrusion 122 is arranged in the guide groove 131. That is, the guide assembly 13 is a planar guide member, which drives the protrusion 122 to move in the third direction Z while driving the ejector 121 to move towards or away from the first holding member 111 in the first direction X. Figure 12 As shown in FIGS. 1, 2 and 11, the guide assembly 13 is provided with a guide groove 131 extending in the third direction Z, and the protrusion 122 is arranged in the guide groove 131. That is, the guide assembly 13 is a planar guide member, which drives the protrusion 122 to move in the third direction Z while driving the ejector 121 to move towards or away from the first holding member 111 in the first direction X.

[0108] As shown in FIGS. 1, 2 and 11, the guide assembly 13 is provided with a guide groove 131 extending in the third direction Z, and the protrusion 122 is arranged in the guide groove 131. That is, the guide assembly 13 is a planar guide member, which drives the protrusion 122 to move in the third direction Z while driving the ejector 121 to move towards or away from the first holding member 111 in the first direction X. Figure 12 As shown in FIGS. 1, 2 and 11, the guide assembly 13 is provided with a guide groove 131 extending in the third direction Z, and the protrusion 122 is arranged in the guide groove 131. That is, the guide assembly 13 is a planar guide member, which drives the protrusion 122 to move in the third direction Z while driving the ejector 121 to move towards or away from the first holding member 111 in the first direction X.

[0109] By setting the guiding assembly 13, the protrusion 122 gradually moves towards the to-cup 8 in the first direction X while moving in the third direction Z in the guiding groove 131, and finally pushes out the battery cell 7 in the to-cup 8, completing the stripping of the battery cell 7 in the to-cup 8. The whole battery cell stripping device 1 has simple structure and small floor area, and can effectively improve the stripping efficiency of the battery cell 7.

[0110] As shown in Figures 6 to 11 and Figure 16 In some embodiments, the holding and taking assembly 11 further comprises a holding and taking mount 113 and a second holding and taking piece 112. The second holding and taking piece 112 is used to hold and take the battery cell 7, and the second holding and taking piece 112 and the first holding and taking piece 111 are arranged in the holding and taking mount 113 in the first direction X.

[0111] Similarly, the second holding and taking piece 112 can be a mechanical gripper, which can realize the grasping and releasing of the material by driving a plurality of movable claws to open and close; the second holding and taking piece 112 can also be a suction accessory, which can fix the to-cup 8 by suction force. It should be noted that the suction accessory can be a negative pressure device, which can fix the to-cup 8 by negative pressure generated by negative pressure extraction of the second holding and taking piece 112. When the to-cup is made of magnetic material such as iron, the suction device can also be a magnetic device, which can fix the to-cup 8 by magnetic force generated by an electromagnet or a permanent magnet.

[0112] By setting the second holding and taking piece 112, the second holding and taking piece 112 can fix the battery cell 7 after the battery cell 7 is stripped from the to-cup 8, which can prevent the battery cell 7 from falling on one hand, and can ensure the relative position of the battery cell 7 on the other hand, thereby facilitating the subsequent transfer or processing of the battery cell 7.

[0113] In some embodiments, the first holding and taking piece 111 and / or the second holding and taking piece 112 is a suction accessory.

[0114] The suction accessory refers to a component that can fix the material by negative pressure generated by negative pressure extraction or magnetic force generated by a magnetic part. In some embodiments, one of the first holding and taking piece 111 and the second holding and taking piece 112 is a suction accessory; and in other embodiments, both the first holding and taking piece 111 and the second holding and taking piece 112 are suction accessories.

[0115] As shown in Figure 11 , 12 and 15, in some embodiments, the second holding and taking piece 112 is a magnetic suction accessory, the second holding and taking piece 112 comprises a containing part 1121 and a magnetic part 1122 arranged in the containing part 1121, and the magnetic part 1122 does not directly contact the battery cell 7.

[0116] The second holding member 112 is a magnetic attraction member, that is, the second holding member is fixed to the battery cell 7 by magnetic force generated by an electromagnet or a permanent magnet. Specifically, the second holding member 112 includes a receiving portion 1121 and a magnetic portion 1122 arranged in the receiving portion 1121. The magnetic portion 1122 is received in the receiving portion 1121 so that the magnetic portion 1122 is fixed in the second holding member 112, thereby generating a magnetic attraction force to attract and fix the battery cell 7.

[0117] The magnetic portion 1122 does not directly contact the battery cell 7, that is, the receiving portion 1121 does not communicate with the surface of the battery cell 7 held by the second holding member 112, and when the magnetic portion 1122 is received in the receiving portion 1121, there is a partition wall between the magnetic portion 1122 and the surface of the battery cell 7 held by the second holding member 112.

[0118] Since the magnetic portion 1122 can attract metal dust generated during production, arranging the magnetic portion 1122 in the receiving portion 1121 and not directly contacting the battery cell 7 can reduce the magnetic force provided by the magnetic portion 1122, reduce the attraction of metal dust, prevent damage to the surface of the battery cell 7 by metal dust, and improve the production quality of the battery cell 7.

[0119] In some embodiments, the second holding member 112 includes two magnetic portions 1122. The two magnetic portions 1122 are arranged at two ends of the second holding member 112 along the first direction X, so as to increase the attraction force of the second holding member 112 to the battery cell 7 and prevent the battery cell 7 from falling off the second holding member 112.

[0120] As shown in FIG. 1, Figure 13 In some embodiments, the battery cell separating device 1 further includes a first demagnetization assembly 14 arranged on the side of the second holding member 112 away from the battery cell 7, and the first demagnetization assembly 14 is movable along the second direction Y to separate the battery cell 7 from the second holding member 112.

[0121] By arranging the first demagnetization assembly 14, when it is necessary to separate the battery cell 7 from the second holding member 112, the first demagnetization assembly 14 is moved along the second direction Y, thereby pushing the battery cell 7 to move along the second direction Y, and finally achieving the separation of the battery cell 7 from the second holding member 112.

[0122] As shown in FIG. 1, Figure 15As shown, in some embodiments, the second holding part 112 is provided with a mounting hole 1123 extending along the second direction Y, and the first demagnetization assembly 14 comprises a push block 141, a push rod 142 and an elastic member 143. The push block 141 is movably arranged in the mounting hole 1123 along the second direction Y; the push rod 142 is connected to the push block 141 through the holding mounting member 113; and the elastic member 143 is sleeved on the push rod 142, and one end of the elastic member 143 abuts against the holding mounting member 113, and the other end abuts against the push rod 142.

[0123] The push block 141 is movably arranged in the mounting hole 1123 along the second direction Y, and the push rod 142 is connected to the push block 141 through the holding mounting member 113. When the push rod 142 moves along the second direction Y, the push block 141 can be pushed to move along the second direction Y in the mounting hole 1123, so as to abut against the battery cell 7 held on the second holding member 112. When the pushing force of the push block 141 is greater than the magnetic force of the magnetic part 1122, the battery cell 7 can be separated from the second holding member 112, so as to realize the unloading of the battery cell 7 from the second holding member 112.

[0124] The elastic member 143 can be a spring or an elastic component such as rubber, and the embodiments of the present application do not limit the same. The elastic member 143 is sleeved on the push rod 142, and when the elastic member 143 is compressed, the elastic member 143 can be guided and positioned, so as to prevent the elastic member 143 from being separated from the first demagnetization assembly 14. By arranging the elastic member 143, when the push block 141 abuts against the battery cell 7, the elastic member 143 can play a buffering role, so as to prevent the instantaneous pushing force from being too large and damaging the battery cell 7. In addition, by arranging the elastic member 143, when the external force is removed, the push rod 142 can be retracted under the action of the elastic force, and then drive the push block 141 to retract into the mounting hole 1123, so as to ensure the holding and fixing of the subsequent battery cell 7 by the second holding member 112.

[0125] As shown, Figures 1 to 4 Another aspect of the present application provides a battery cell unloading system. The battery cell unloading system comprises a conveying line 2 and a battery cell separating device 1. The conveying line 2 conveys the cup 8 along a preset direction; and the battery cell separating device 1 is arranged on one side of the conveying line 2 along a second direction Y.

[0126] The conveying line 2 refers to a component for conveying materials. Specifically, the conveying line 2 can be a belt, a chain or other conveying components, and sequentially conveys the cup 8 to the battery cell separating device 1 along a preset direction.

[0127] The battery cell separating device 1 is arranged on one side of the conveying line 2 along the second direction Y, and is used to separate the battery cell 7 in the cup 8 on the conveying line 2 from the cup 8.

[0128] As shown, Figure 6 and Figure 7As shown, in some embodiments, the battery cell separating device 1 further comprises a mounting member 15, the plurality of holding and taking assemblies 11 and the plurality of ejection assemblies 12 are spaced apart along the third direction Z on the mounting member 15, and the mounting member 15 is movably arranged along the third direction Z to sequentially transport the plurality of holding and taking assemblies 11 and the plurality of ejection assemblies 12 to the guiding assembly 13.

[0129] The plurality of holding and taking assemblies 11 and the plurality of ejection assemblies 12 are arranged on the mounting member 15, and when the mounting member 15 moves along the third direction Z, the holding and taking assemblies 11 and the ejection assemblies 12 on the mounting member 15 can be gradually moved along the third direction Z to approach the guiding assembly 13, and finally, under the guidance of the guiding groove 131, the plurality of battery cells 7 on the plurality of holding and taking assemblies 11 can be sequentially ejected from the plurality of holding cups 8, so that the discharging of the plurality of battery cells 7 can be realized by one movement of the mounting member 15, and the discharging efficiency of the battery cells 7 is improved.

[0130] As shown in FIGS. Figure 1 , 2 and 6 to 9, in some embodiments, the battery cell discharging system further comprises a pushing device 3, and the pushing device 3 comprises a pushing mounting member 31 and a pushing member 32. The pushing mounting member 31 is arranged on the side of the conveying line 2 away from the battery cell separating device 1 along the second direction Y, and the pushing member 32 is movably arranged on the pushing mounting member 31 along the second direction Y to push the plurality of holding cups 8 on the conveying line 2 into the battery cell separating device 1.

[0131] The pushing mounting member 31 is arranged on the side of the conveying line 2 away from the battery cell separating device 1 along the second direction Y, that is, the pushing mounting member 31 and the battery cell separating device 1 are arranged on the two sides of the conveying line 2 along the second direction Y.

[0132] The pushing member 32 is movably arranged on the pushing mounting member 31 along the second direction Y. Specifically, the movable connection between the pushing member 32 and the pushing mounting member 31 can be realized by a guide rail and a sliding block mechanism or by a lead screw, and the present application does not limit this. For example, in some embodiments, a guide rail extending along the second direction Y is arranged on one of the pushing member 32 and the pushing mounting member 31, and a sliding block is arranged on the other one, and the movement of the sliding block on the guide rail can realize the movement of the pushing member 32 relative to the pushing mounting member 31 along the second direction Y.

[0133] By arranging the pushing device 3, when the pushing member 32 moves relative to the pushing mounting member 31 along the second direction Y, the pushing member 32 can push the plurality of holding cups 8 on the conveying line 2 into the first holding and taking member 111 of the battery cell separating device 2, so as to facilitate the subsequent discharging of the battery cells 7 in the plurality of holding cups 8.

[0134] As shown in FIGS. Figure 3 , 9As shown in Figure 10, in some embodiments, the conveyor line 2 includes a feeding area 21, a buffer area 22, and a return area 23. The feeding area 21 is correspondingly disposed to the cell separation device 1, and the guiding component 13 is disposed downstream of the feeding area 21. The buffer area 22 is disposed along the second direction Y on the side of the feeding area 21 opposite to the cell separation device 1, and the pushing device 3 is used to push the cup 8 from the buffer area 22 into the feeding area 21. The return area 23 is connected to the feeding area 21 to return the cup 8 after feeding.

[0135] The unloading area 21 refers to the area on the conveyor line 2 corresponding to the cell separation device 1, where the cells 7 are unloaded from the cups 8. The buffer area 22 refers to the area on the conveyor line 2 used to buffer the cups 8. By setting up the buffer area 22, the correct number of cups 8 can be conveyed to the unloading area 21. The return area 23 is the area on the conveyor line where the unloaded cups 8 are returned to their designated location, facilitating the collection and storage of the cups 8 or the continued handling of new cells 7.

[0136] Specifically, after the cup 8 is fed to the conveyor line 2, it is first conveyed to the buffer area 22 on the conveyor line 2. When the number of cups 8 on the buffer area 22 reaches a predetermined number (the same as the number of the first holding member 111 on the cell separation device 1), the pushing device 2 pushes the cups 8 on the buffer area 22 onto the first holding member 111 on the unloading area 21. After the cell 7 is unloaded from the cup 8 in the unloading area 21, the unloaded cup 8 is finally conveyed to the subsequent station through the return area 23.

[0137] like Figures 6 to 9 As shown, in some embodiments, the cell feeding system further includes a protective device 9, which includes a protective member 91 disposed along the second direction Y on the side of the buffer area 22 away from the feeding area 21. The protective member 91 extends along the third direction Z to prevent the cup 8 from falling from the feeding area 21.

[0138] The protective component 91 is disposed along the second direction Y on the side of the buffer area 22 away from the unloading area 21. By setting the protective component 91, when the cup 8 flows into the buffer area 22, the protective component 91 can protect the cup 8 and prevent the cup 8 from falling off the edge of the buffer area 22 when it flows into the buffer area 22 along the third direction Z, thus ensuring the smooth unloading of the battery cell 7.

[0139] In some embodiments, the material protector 91 is provided with a clearance notch to ensure that the pusher 32 can pass through the clearance notch through the material protector 91 and push the cup 8 to move along the second direction Y, thereby pushing the cup 8 from the buffer area 21 into the first holding member 111 of the unloading area 21, thus completing the separation of the battery cell 7 and the cup 8.

[0140] In other embodiments, such as Figure 6As shown, the material protection device 9 further comprises a material protection mounting 92, and the material protection piece 91 is movably arranged on the material protection mounting 92 along the first direction X to avoid the pushing piece 32.

[0141] The material protection piece 91 is movably arranged on the material protection mounting 92 along the first direction X. Specifically, the movable connection between the material protection piece 91 and the material protection mounting 92 can be realized by a guide rail and slider mechanism or by a lead screw, and the present application embodiments do not limit this. For example, in some embodiments, a guide rail extending along the first direction X is arranged on one of the material protection piece 91 and the material protection mounting 92, and a slider is arranged on the other one, and the movement of the slider on the guide rail realizes the movement of the material protection piece 91 relative to the material protection mounting 92 along the first direction X.

[0142] By movably arranging the material protection piece 91 on the material protection mounting 91 along the first direction X, before pushing, the material protection piece 91 can be moved along the first direction X to approach the buffer area 22 on the conveying line 2, so that when the cup holder 8 flows into the buffer area 22, the material protection piece 91 can protect the cup holder 8 from falling off the edge of the buffer area 22 when the cup holder 8 flows into the buffer area 22 along the third direction Z. When pushing, the material protection piece 33 can be moved away from the buffer area 22 on the conveying line 2 along the first direction X to avoid the pushing piece 32, so that the pushing piece 32 can move along the second direction Y to push the cup holder from the buffer area 21 to the first holding piece 111 of the discharging area 21 to complete the separation of the battery cell 7 and the cup holder 8.

[0143] As shown in Figure 6 and 8 In some embodiments, one end of the material protection mounting 92 is connected with the pushing piece 32, and the other end is connected with the material protection piece 91. Specifically, the connection between the material protection mounting 92 and the pushing piece 32 can be a detachable connection mode such as bolt connection or clamping, or a non-detachable connection mode such as welding or bonding, and the present application embodiments do not limit this.

[0144] By connecting the material protection mounting 92 with the pushing piece 32, that is, by mounting the material protection device 9 in the pushing device 3 without the need for additional mounting components to fixedly mount the material protection device 9, the structure of the battery cell discharging system can be more compact.

[0145] As shown in Figure 1 and Figure 2 In some embodiments, the battery cell discharging system further comprises a material blocking device 4 arranged upstream of the pushing device 3 to control the number of cup holders 8 entering the buffer area 22.

[0146] The blocking device 4 can cut off the passage between the upstream of the conveying line 2 and the buffer area 22, thereby controlling the number of the cup carriers entering the buffer area 22. Specifically, in some embodiments, the blocking device 4 comprises a blocking member and a driving member in driving connection with the blocking member, the driving member being configured to drive the blocking member to extend into or exit from the conveying line 2, thereby blocking or releasing the cup carriers 8. For example, when it is required to block the cup carriers 8 from entering the buffer area 22, the driving member drives the blocking member to extend into the conveying line 2, thereby blocking the cup carriers 8 in the conveying line 2 from moving further. When it is required to release the cup carriers 8 to enter the buffer area 22, the driving member drives the blocking member to retract, thereby releasing the cup carriers 8 in the conveying line 2.

[0147] By providing the blocking device 4, the number of the cup carriers 8 entering the buffer area 22 can be accurately controlled, thereby ensuring that the number of the cup carriers 8 pushed by the pushing device 3 into the battery cell separating device 1 corresponds to the number of the holding and taking assemblies 11 in the battery cell separating device 1, and ensuring the orderly progress of the battery cell 7 unloading process.

[0148] As shown in FIGS. Figure 1 , 4 and Figures 19 to 21 , in some embodiments, the battery cell unloading system further comprises a transferring device 5 arranged downstream of the guiding assembly 13 and configured to transfer the battery cells 7 on the second holding and taking member 112.

[0149] The transferring device 5 refers to a component configured to transfer the battery cells 7 on the second holding and taking member 112. Specifically, the transferring device 5 can be a robot, which is configured to take away the battery cells 7 on the second holding and taking member 112 by mechanical grippers or suction members.

[0150] By providing the transferring device 5, the battery cells 7 separated from the cup carriers 8 can be transferred and carried, so as to be processed or collected and stored subsequently.

[0151] As shown in FIGS. Figure 1 , 4 and Figures 19 to 21 , in some embodiments, the transferring device 5 is arranged on the side of the conveying line 2 away from the battery cell separating device 1 along the second direction Y, and the transferring device 5 comprises a transferring mounting member 51 and a third holding and taking member 52. A plurality of third holding and taking members 52 are arranged at intervals along a third direction Z, so as to receive the battery cells 7 on the second holding and taking member 112.

[0152] The transferring device 5 is arranged on the side of the conveying line 2 away from the battery cell separating device 1 along the second direction Y, that is, the transferring device 5 and the battery cell separating device 1 are arranged on the two sides of the conveying line 2 along the second direction Y, respectively.

[0153] Similarly, the third gripper 52 can be a mechanical claw, which opens and closes multiple movable claws to grasp and release the battery cell 7. The third gripper 52 can also be an adsorption device, which uses adsorption force to hold and fix the battery cell 7. It should be noted that in this case, the adsorption device can be a negative pressure device, which uses the generated negative pressure to hold and fix the battery cell 7. When the battery cell is made of magnetic materials such as iron, the adsorption device can also be a magnetic device, which uses the magnetic force generated by an electromagnet or a permanent magnet to hold and fix the battery cell 7.

[0154] In some embodiments, the number of third holding members 52 is the same as the number of second holding members 112, and the spacing between each third holding member 52 along the third direction Z is also the same as the spacing between each second holding member 112 along the third direction Z, so as to ensure that each second holding member 112 has a corresponding third holding member 52, so that all the cells 7 in the cell separation device 1 can be transferred in one transfer process of the transfer device 5, thereby improving production efficiency.

[0155] like Figures 19 to 21 As shown, in some embodiments, the plurality of third holding members 52 are spaced at adjustable intervals along the third direction Z.

[0156] Multiple third holding components 52 are spaced at adjustable intervals along the third direction Z, meaning the distance between two adjacent third holding components 52 can be adjusted. On the one hand, this can be used to adapt to different specifications of the battery cell separation device 1, improving the practicality of the battery cell unloading system; on the other hand, the spacing between the battery cells can be readjusted during the transfer of the battery cells 7 to meet different usage scenarios.

[0157] like Figures 19 to 21 As shown, in some embodiments, the third holding member 52 is a magnetic adsorption member, and the transfer device 5 further includes a second demagnetizing component 53, which is movable along the second direction Z to separate the battery cell 7 from the third holding member 53. The third holding member 52 is a magnetic adsorption member, meaning that the third holding member 52 uses the magnetic force generated by an electromagnet or permanent magnet to adsorb and fix the battery cell 7. Similarly, in some embodiments, the third holding member 53 may include a receiving portion and a magnetic portion (not shown in the figure) disposed within the receiving portion. By providing a receiving portion to accommodate and fix the magnetic portion, the magnetic portion can be fixed in the third holding member 52, thereby generating a magnetic adsorption force to adsorb and fix the battery cell. In some embodiments, the magnetic portion of the third holding member 52 does not directly contact the battery cell 7 to reduce the magnetic force provided by the magnetic portion, reduce the adsorption of metal dust, prevent metal dust from damaging the surface of the battery cell 7, and improve the production quality of the battery cell 7.

[0158] Similarly, the structure of the second demagnetizing component 53 can be the same as that of the first demagnetizing component 14, and will not be described again in this embodiment.

[0159] By setting the second demagnetization assembly 53, when it is needed to separate the battery cell 7 from the transfer device 5 and place it into the next station or tray, the battery cell 7 can be easily separated from the transfer device 5 by the second demagnetization assembly 53.

[0160] As shown in Figure 20 and Figure 21 , in some embodiments, the transfer device 5 further comprises a rack 54, and the transfer mount 51 is rotatably arranged on the rack 54 to adjust the posture of the battery cell 7.

[0161] The transfer mount 51 is rotatably arranged on the rack 54, specifically, the transfer mount 51 can be arranged on the rack 54 through a rotating shaft to realize the rotation of the transfer mount 51 relative to the rack 54.

[0162] By rotatably arranging the transfer mount 51 on the rack 54, when the transfer mount 51 rotates relative to the rack 54, the third gripper 52 on the transfer mount 51 can also rotate relative to the rack 54, so that the posture of the battery cell 7 on the third gripper 52 can be adjusted. For example, when the transfer mount 51 rotates 90° relative to the rack 54, the battery cell 7 on the third gripper 52 can be adjusted from a vertical state to a horizontal state, thereby facilitating the horizontal storage of the battery cell 7 in the tray. Compared with vertical storage, horizontal storage can lower the center of gravity of the battery cell 7, prevent the battery cell 7 from overturning during storage, and improve the stability and safety of the battery cell 7 during storage.

[0163] As shown in Figure 17 and 18 , in some embodiments, the battery cell separation device 1 further comprises a demagnetization driving part 16 arranged corresponding to the transfer device 5 along the second direction Y, and the demagnetization driving part 16 is used to drive the push rod 142 to move along the second direction Y to push the battery cell 7 from the second gripper 112 into the third gripper 52.

[0164] The demagnetization driving part 16 is arranged corresponding to the transfer device 5 along the second direction Y, that is, the demagnetization driving part 16 and the transfer device 5 are respectively arranged on both sides of the conveying line 2 along the second direction Y.

[0165] By arranging the demagnetization driving part 16 to push the push rod 142 to move along the second direction Y, the push block 141 and the battery cell 7 are abutted, so that the battery cell 7 is separated from the second gripper 112 and pushed into the third gripper 52.

[0166] In some embodiments, the demagnetization driving part 16 further comprises a driving source and a driving part arranged with the driving source, the driving part is arranged to extend along the third direction Z, when the driving source drives the driving part to move, the driving part extending along the third direction can simultaneously abut against multiple push rods 142 of the first demagnetization assembly 14 to simultaneously complete the discharging of the multiple second holding pieces 112 on the battery cell 7. At this time, the driving part can be an electric cylinder, a pneumatic cylinder, a hydraulic cylinder or the like, and the embodiments of the present application do not limit this.

[0167] As shown in Figure 1 and Figure 22 In some embodiments, the battery cell discharging system further comprises a feeding device 6, the feeding device 6 comprises a feeding port 61, a discharging port 62 and a cup conveying assembly 63. Wherein, the discharging port 62 is arranged in communication with the conveying line 2; the cup conveying assembly 63 is in communication with the feeding port 61 and the discharging port 62.

[0168] By arranging the feeding device 6, the cup 8 can be conveyed from the feeding port 61 to the discharging port 62, and finally fed into the conveying line 2, so as to complete the subsequent battery cell 7 discharging process.

[0169] As shown in Figure 22 In some embodiments, the conveying assembly 63 comprises a feeding turntable 631, a discharging turntable 632, a transition turntable 633 and a monitoring and identifying part 634. Wherein, the feeding turntable 631 is arranged corresponding to the feeding port 61; the discharging turntable 632 is arranged corresponding to the discharging port 62; the transition turntable 633 is arranged between the feeding turntable 631 and the discharging turntable 632; the monitoring and identifying part 634 is arranged on one side of the transition turntable 633, and is used for monitoring and / or identifying the battery cell 7 and the cup 8.

[0170] In some embodiments, the monitoring and identifying part 634 can be a CCD image recognition device, which is used for monitoring the appearance quality of the battery cell 7 and the cup 8. In other embodiments, the monitoring and identifying part 634 can also be a code scanning device, which is used for identifying the two-dimensional code on the cup 8 and the battery cell 7 to obtain the information of the cup 8 and the battery cell 7.

[0171] Specifically, when the cup 8 is fed, the cup 8 first reaches the feeding turntable 631, and then is conveyed to the transition turntable 632 through the feeding turntable 631, and the cup 8 and the battery cell 7 are detected and identified on the transition turntable 632 to ensure the quality of the battery cell 2 and the cup 8 entering the conveying line 2.

[0172] As shown in Figure 22 In some embodiments, the conveying assembly 63 further comprises a rejection turntable 635 arranged on one side of the discharging turntable 632 to reject unqualified battery cells 7 and cups 8.

[0173] Specifically, when the monitoring and identifying member 634 identifies that the battery cell 7 or the cup 8 has a quality problem or its two-dimensional code identification is incorrect, the rejection carousel 635 will transfer the cup 8 from the unloading carousel 632 to the rejection carousel 635, and finally reject the cup 8 from the feeding device 6.

[0174] As shown in FIG. 6, in some embodiments, the feeding assembly 63 further comprises a rejection member 636 arranged between the unloading carousel 632 and the rejection carousel 635, and the rejection member 636 is movable towards the rejection carousel 635 to push the unqualified battery cell 7 and cup 8 from the unloading carousel 632 to the rejection carousel 635. Figure 22 By arranging the rejection member 636, when the monitoring and identifying member 634 identifies that the battery cell 7 or the cup 8 has a quality problem or its two-dimensional code identification is incorrect, the rejection member 636 will push the cup 8 from the unloading carousel 632 to the rejection carousel 635, thereby completing the rejection of unqualified products and ensuring the production quality of the battery cell 7.

[0175] Specifically, as shown in FIG. 6, during feeding, one end of the battery cell 7 is inserted into the cup 8, the cup 8 enters the feeding device 6 from the feeding port 61, first reaches the feeding carousel 631, and then is conveyed to the transition carousel 632 by the feeding carousel 631. The monitoring and identifying member 634 detects and identifies the cup 8 and the battery cell 7 on the transition carousel 632. When the monitoring and identifying member 634 detects that the cup 8 or the battery cell 7 is unqualified, the rejection member 636 will push the cup 8 from the unloading carousel 632 to the rejection carousel 635, thereby completing the rejection of unqualified products; and when the monitoring is qualified, the cup 8 and the battery cell 7 are conveyed from the unloading carousel 632 to the conveying line 2 through the discharge port, thereby completing the feeding of the cup 8 and the battery cell 7.

[0176] Figures 1 to 22 Subsequently, the cup 8 is conveyed to the buffer area 22 of the conveying line 2, and when the number of cups 8 on the buffer area 22 reaches a preset value (consistent with the number of the first holding member 111), the blocking device 4 extends into the conveying line 2 to block the subsequent cups 8 from being continuously conveyed.

[0177] Subsequently, the blocking member 91 moves away from the buffer area 22 along the first direction X, and the pushing member 32 moves towards the battery cell separating device 1 along the second direction Y, thereby pushing the cup 8 on the buffer area 22 into the battery cell separating device 1 of the feeding area 21, and the cup 8 is held and fixed on the first holding member 111.

[0178] Subsequently, the blocking member 91 moves away from the buffer area 22 along the first direction X, and the pushing member 32 moves towards the battery cell separating device 1 along the second direction Y, thereby pushing the cup 8 on the buffer area 22 into the battery cell separating device 1 of the feeding area 21, and the cup 8 is held and fixed on the first holding member 111.

[0179] ​Subsequently, the cell separating device 1 moves along the third direction Z, at this time, the protrusion 122 gradually approaches the first holding piece 111 along the first direction X under the guidance of the guide groove 131, so that the ejector 121 extends into the cup 8, the cell 7 in the cup 8 is ejected and adsorbed and fixed on the second holding piece 112. Subsequently, the guide groove 131 guides the protrusion 122 to gradually move away from the first holding piece 111 along the first direction X, so that the ejector 121 exits the cup 8. The cup 8 flows back into the conveying line 2 under the action of the backflow area 23.

[0180] When the cell separating device 1 moves to the position corresponding to the transfer device 5 along the third direction Z, the demagnetization driving part 16 pushes the push rod 142 to compress the elastic piece 143 to push the push block 141 to gradually approach the cell 7 along the second direction Y and abut against the cell 7. When the pushing force of the push block 141 is greater than the adsorption force of the second holding piece 112, the cell 7 is separated from the second holding piece 112 and pushed onto the third holding piece 52, and the transfer of the cell 7 from the cell separating device 1 to the transfer device 5 is completed. Subsequently, the demagnetization driving part 16 retreats, and the push rod 142 returns to the initial position under the elastic force of the elastic piece 143.

[0181] Finally, the transfer mounting part 51 of the transfer device 5 rotates 90° relative to the frame 54, adjusts the cell 7 from the vertical state to the horizontal state, and finally releases the cell 7 under the action of the second demagnetization assembly 53 and places the cell 7 horizontally into the tray. Thus, the whole process of separating the cell 7 from the cup 8 is completed.

[0182] The technical features of the above-described embodiments can be combined in any manner. To make the description concise, all possible combinations of the technical features in the above-described embodiments are not described, but as long as the combinations of the technical features do not contradict each other, they should be considered within the scope of the present disclosure.

[0183] The above-described embodiments only express several implementation manners of the present application, and the description is relatively specific and detailed, but it should not be understood as a limitation on the scope of the present application. It should be pointed out that for ordinary skilled persons in the art, without departing from the concept of the present application, a number of modifications and improvements can be made, which are all within the protection scope of the present application.
