[0070] In order to make the objects, technical solutions and advantages of the embodiments of the present application clearer, the technical solutions in the embodiments of the present application will be described clearly below with reference to the drawings in the embodiments of the present application. Obviously, the described embodiments are only some but not all of the embodiments of the present application. Based on the embodiments in the present application, all other embodiments obtained by a person of ordinary skill in the art without creative work fall within the protection scope of the present application.

[0071] Unless otherwise defined, all technical and scientific terms used in the present application have the same meaning as commonly understood by one of ordinary skill in the art to which the present application belongs; the terms used in the specification of the present application are only for the purpose of describing the specific embodiments and are not intended to limit the present application; the terms "include" and "have" and any variations thereof in the specification and claims of the present application and the above description of drawings are intended to cover non-exclusive inclusion. The terms "first", "second" and the like in the specification and claims of the present application and the above description of drawings are used to distinguish different objects, and are not intended to describe a particular order or primary and secondary relationship.

[0072] In the present application, the phrase "embodiment" means that the specific features, structures or characteristics described in connection with the embodiment can be included in at least one embodiment of the present application. The phrase appears at various places in the specification does not necessarily refer to the same embodiment, nor is it mutually exclusive or alternative to other embodiments.

[0073] In the description of the present application, it should be noted that unless otherwise explicitly specified and limited, the terms "mount", "connect", "connection", "attach" should be understood broadly, for example, can be fixedly connected, can be detachably connected, or integrally connected; can be directly connected, or indirectly connected through an intermediate medium; can be internal communication of two elements. For a person of ordinary skill in the art, the specific meaning of the above terms in the present application can be understood according to the specific circumstances.

[0074] The term "and / or", as used in this application, is merely an association relationship between associated objects, which means that there can be three relationships, for example, A and / or B, which can represent the three cases of A alone, A and B together, and B alone. In addition, the character " / " in this application generally represents an "or" relationship between the front and rear associated objects.

[0075] In the embodiments of the present application, the same reference signs represent the same components, and for the sake of brevity, detailed descriptions of the same components are omitted in different embodiments. It should be understood that the thickness, length, width and other dimensions of various components in the embodiments of the present application shown in the drawings, as well as the overall thickness, length, width and other dimensions of the integrated device, are only exemplary and should not constitute any limitation on the present application.

[0076] "Multiple" appearing in the present application means two or more (including two).

[0077] In the present application, the battery cell can include a lithium ion secondary battery cell, a lithium ion primary battery cell, a lithium-sulfur battery cell, a sodium lithium ion battery cell, a sodium ion battery cell, or a magnesium ion battery cell, etc. The present application embodiments are not limited thereto. The battery cell can be in the shape of a cylinder, a flat body, a cuboid, or other shapes, etc. The present application embodiments are also not limited thereto.

[0078] After the battery cell is completed, it is usually necessary to apply a thermal insulation pad to the outer surface of the battery cell, which serves as a barrier to the spread of thermal runaway of the battery cell and provides cushioning, support, and insulation, etc. In some cases, in the process of applying the thermal insulation pad, the battery cell needs to be grabbed by a mechanical hand or other handling mechanism and placed on a conveying line. After the conveying line conveys the battery cell to the application station, the operator or the mechanical hand applies the thermal insulation pad to the battery cell, and then the conveying line continues to convey the battery cell. The mechanical hand grabs the battery cell from the conveying line and places it in a receiving tray.

[0079] In the above-mentioned application process, the battery cell needs to be grabbed and placed twice by the mechanical hand, and each grabbing and placing takes a long time, resulting in low operation efficiency of the battery cell.

[0080] In view of this, the present application provides a conveying device which utilizes an inverted tooling to walk on a first magnetic levitation track, and the guide structure on the frame body guides the upward and / or downward movement of the inverted tooling, thereby realizing the grabbing or placing of the battery cell. In this way, the use of the handling mechanism can be reduced, and the operation efficiency of the battery cell can be improved.

[0081] The technical solutions described in the embodiments of the present application are applicable to various processes that require processing of the outer surface of the battery cell, such as applying a thermal insulation pad to the outer surface of the battery cell, or performing OCV testing on the battery cell, etc.

[0083] As shown in Figures 1-4 The present application provides a conveying device 100, which comprises a magnetic driving conveying mechanism 1 and a hanging tool 2. The magnetic driving conveying mechanism 1 comprises a frame body 11, a first magnetic levitation track 12 and a first magnetic levitation mover 13. The first magnetic levitation track 12 is arranged on the frame body 11, and the first magnetic levitation mover 13 is configured to move along the first magnetic levitation track 12 under the driving of magnetic force. The hanging tool 2 comprises a following assembly 21 and a grabbing assembly 22. The following assembly 21 comprises a first part 211 and a second part 212 which are movably connected. The first part 211 is connected to the first magnetic levitation mover 13, and the grabbing assembly 22 is connected to the second part 212 and is used for grabbing and placing a battery monomer 200. The frame body 11 is provided with a guide structure 14 which is arranged side by side with the first magnetic levitation track 12 and is located below the first magnetic levitation track 12. The second part 212 is in sliding or rolling cooperation with the guide structure 14. The guide structure 14 comprises a height adjusting section 141 and a working section 142 which are connected. The maximum distance between the height adjusting section 141 and the first magnetic levitation track 12 is greater than the maximum distance between the working section 142 and the first magnetic levitation track 12. The second part 212 drives the grabbing assembly 22 to rise and / or fall under the limitation of the height adjusting section 141, so as to adjust the height of the grabbing assembly 22. The working section 142 is used for target operation on the battery monomer 200.

[0084] For example, the first magnetic levitation track 12 is provided with a multi-phase armature winding. By injecting alternating currents with different phases into the multi-phase armature winding, a moving magnetic field (also known as a traveling wave magnetic field) with a controllable moving direction can be generated in the track direction. The first magnetic levitation mover 13 is provided with an excitation magnet (such as an array of permanent magnets). The moving magnetic field interacts with the magnetic field generated by the excitation magnet to generate a continuous electromagnetic thrust on the mover based on the principle of electromagnetic induction, thereby driving the first magnetic levitation mover 13 to move in suspension without contact along the track. By adjusting the phase and frequency of the current input to the winding, the moving direction and speed of the generated traveling wave magnetic field are changed, thereby controlling the direction of the electromagnetic thrust acting on the first magnetic levitation mover 13, and realizing the precise control of acceleration, constant speed and braking of the first magnetic levitation mover 13.

[0085] The first magnetic levitation track 12 of the present embodiment can be linear or have a curved section.

[0086] The first part 211 and the second part 212 of the embodiment can be movably connected, which can be in the form of sliding connection, or rolling connection, or other forms. The direction of the movable connection between the two can be along the vertical direction, or along other directions.

[0087] For example, the guide structure 14 can be a guide rail structure, and the second part 212 is provided with a rotatable clamping groove structure, which is in sliding fit with the guide rail structure to realize the walking of the clamping groove structure on the height adjustment section 141.

[0088] The height adjustment section 141 of the embodiment can be an inclined straight section, or a curved section.

[0089] Optionally, the extension direction of the working section 142 is parallel to the horizontal direction.

[0090] The target operation of the embodiment can be the lamination operation of the battery monomer 200 and the heat insulation pad, or the OCV test of the battery monomer 200.

[0091] In a specific embodiment, the height adjustment section 141 includes an ascending sub-section, the ascending sub-section is connected with the working section 142, the following assembly 21 follows the guide structure 14 to walk, the grabbing assembly 22 grabs the battery monomer 200 in the area of the ascending sub-section, and follows the ascending sub-section to ascend, and after entering the working section 142, the operator or the mechanical hand carries out the lamination process of the battery monomer 200 and the heat insulation pad.

[0092] In a specific embodiment, the height adjustment section 141 includes a descending sub-section, the descending sub-section is connected with the working section 142, the following assembly 21 follows the guide structure 14 to walk in the working section 142, the operator or the mechanical hand carries out the lamination process of the battery monomer 200 and the heat insulation pad, and then enters the descending sub-section, follows the descending sub-section to descend, and the grabbing assembly 22 places the battery monomer 200 in the area of the descending sub-section.

[0093] In a specific embodiment, when the height adjustment section 141 includes both the ascending sub-section and the descending sub-section, the guide structure 14 can be used only for the grabbing assembly 22 to grab the battery monomer, or only for the grabbing assembly 22 to place the battery monomer, or for the grabbing assembly 22 to grab and place the battery monomer, for example, to place at the descending sub-section and to grab at the ascending sub-section.

[0094] The conveying device 100 of the embodiment utilizes the inverted tooling 2 to walk on the first magnetic suspension track 12, and the guide structure 14 on the frame body 11 guides the inverted tooling 2 to ascend and / or descend, which is used for the grabbing of the battery monomer 200 before the target operation, or the placing of the battery monomer 200 after the target operation, so as to reduce the use of the carrying mechanism and improve the efficiency of the target operation of the battery monomer 200.

[0095] And, the guide structure 14 on the frame 11 is used to realize the lifting and / or lowering of the grabbing assembly 22, which is extremely convenient and reliable in use.

[0096] In some embodiments, the height adjustment section 141 comprises an adjustment sub-section 143 and a buffer sub-section 145, the second part 212 drives the grabbing assembly 22 to rise or fall under the limit of the adjustment sub-section 143, one end of the adjustment sub-section 143 in the length direction is connected with the working section 142, the other end of the adjustment sub-section 143 in the length direction is connected with the buffer sub-section 145, the buffer sub-section 145 is farther away from the first magnetic levitation track 12 than the working section 142, and the grabbing assembly 22 is configured to grab and / or place the battery monomer 200 at the buffer sub-section 145.

The buffer sub-section 145 is connected with the working section 142 through the adjustment sub-section 143, and the adjustment sub-section 143 plays a role of transition connection to drive the grabbing assembly 22 to rise or fall.

[0098] The extension direction of the buffer sub-section 145 in the embodiment for grabbing the battery monomer 200 can be determined according to the arrangement of the mechanism for feeding, and the extension direction of the buffer sub-section 145 for placing the battery monomer 200 can be determined according to the arrangement of the mechanism for receiving. When the buffer sub-section 145 is used for both grabbing and placing the battery monomer 200, the extension direction of the buffer sub-section 145 is determined according to the arrangement of the mechanism for feeding and the mechanism for receiving respectively.

[0099] Optionally, the extension direction of the buffer sub-section 145 is parallel to the horizontal direction.

[0100] In a specific embodiment, the grabbing assembly 22 grabs the battery monomer 200 at the buffer sub-section 145 and rises following the adjustment sub-section 143, and then the operator or the mechanical hand carries out the process of attaching the battery monomer 200 and the heat insulation pad in the working section 142.

[0104] In some embodiments, the number of adjustment sub-sections 143 is two, one end of the buffer sub-section 145 in the length direction is connected to one of the adjustment sub-sections 143, and the other end of the buffer sub-section 145 in the length direction is connected to the other adjustment sub-section 143, one of the two adjustment sub-sections 143 is used to drive the grabbing assembly 22 to ascend, and the other is used to drive the grabbing assembly 22 to descend.

[0106] For example, the two adjustment sub-sections 143 are both straight sections, and the slopes of the inclinations thereof can be the same or different.

[0107] Two adjustment sub-sections 143 are arranged, one is used to drive the grabbing assembly 22 to ascend, and the other is used to drive the grabbing assembly 22 to descend, facilitating the loop movement of the inverted tooling 2.

[0108] In some embodiments, the first magnetic levitation track 12 and the guide structure 14 are respectively arranged in a loop, the inverted tooling 2 is configured to move in a loop following the first magnetic levitation track 12 and the guide structure 14, the number of height adjustment sections 141 is two, and the two height adjustment sections 141 are connected through two working sections 142, one of the height adjustment sections 141 is used for the grabbing assembly 22 to grab the battery cell 200, and the other height adjustment section 141 is used for the grabbing assembly 22 to place the battery cell 200.

[0109] The first magnetic levitation track 12 and the guide structure 14 of the embodiment are respectively arranged in a closed loop. Two height adjustment sections 141 are connected by two working sections 142, that is, one height adjustment section 141, one working section 142, another height adjustment section 141, and another working section 142 are sequentially connected to form a closed loop of the guide structure 14.

[0110] In the working state, two working sections 142 of the embodiment are used for target operation of the battery monomer 200.

[0111] In a specific embodiment, after the inverted tooling 2 grabs the battery monomer 200 from the buffer sub-section 145 of one of the height adjustment sections 141, it enters one of the working sections 142 to perform target operation on the battery monomer 200, and then enters the other height adjustment section 141 to place the battery monomer 200 at the buffer sub-section 145 of the other height adjustment section 141. The inverted tooling 2 then enters the other working section 142 and finally returns to one of the height adjustment sections 141 to grab the battery monomer 200 again, and the cycle is repeated. Whether the inverted tooling 2 adopts a clockwise or counterclockwise winding mode needs to be determined according to the actual working conditions.

[0112] The first magnetic levitation track 12 and the guide structure 14 are respectively arranged in a loop, and the inverted tooling 2 walks in a loop, so that multiple inverted toolings 2 can be operated simultaneously to perform target operation on the battery monomer 200, greatly improving the operation efficiency. In addition, the two height adjustment sections 141 are arranged at intervals, facilitating the arrangement of the feeding mechanism 3 and the receiving mechanism 5 at the two height adjustment sections 141.

[0114] In this way, the extension direction of the buffer sub-section 145 is perpendicular to the height direction of the conveying device 100, so that the height of the grabbing assembly 22 at the buffer sub-section 145 remains unchanged, facilitating the grabbing or placing of the battery monomer 200. The extension direction of the working section 142 is perpendicular to the height direction of the conveying device 100, and the height of the working section 142 remains unchanged, so that the optional area range for target operation is larger. The extension direction of the first magnetic levitation track 12 is perpendicular to the height direction of the conveying device 100, so that the first magnetic levitation track 12 extends in the horizontal direction, reducing the difficulty of arranging the first magnetic levitation track 12.
