[0021] The following will be combined with the drawings in the embodiments of the present application to clearly and completely describe the technical solutions in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of this application.

[0022] After the battery cell is wound, an insulating sheet needs to be placed on its side to protect the battery cell.

[0023] See also Figure 1-3 The present application discloses a clipping device for clipping an insulating sheet 10 onto a battery cell 20, which includes: a first carrier 100 for receiving the insulating sheet 10; a flipping mechanism 200, which is arranged on one side of the first carrier 100 and can extract the insulating sheet 10 in the first carrier 100 and flip the insulating sheet 10 from a flat state to a vertical state; a second carrier 300 for receiving the battery cell 20; a transport mechanism 400, which can move between the flipping mechanism 200 and the second carrier 300 to facilitate the transfer of the insulating sheet 10 to the battery cell 20.

[0024] In a specific embodiment, the battery cell 20 is a square battery cell formed by winding, and the insulating sheet 10 is used to cover the winding end of the battery cell 20. It should be explained that the battery cell 20 is formed by folding a continuous substrate and inserting the positive and negative electrodes, and its winding end is the end where multiple layers of substrate and electrode sheets are exposed. Since the substrate and electrode sheets are exposed layer by layer, the winding end is easily compressed and folded. Therefore, when the battery cell 20 is loaded, its winding end should not contact with various mechanisms. For example, when the battery cell 20 is placed on the second carrier 300, its winding end cannot contact the second carrier 300, but will be on the side of the battery cell 20.

[0025] In summary, the position of the battery cell 20 to be buckled with the insulating sheet 10 (that is, the winding end of the battery cell 20 ) is usually the vertically arranged side surface of the battery cell 20 after the battery cell 20 is loaded.

[0026] Specifically, the loading device (not shown) inputs the insulating sheets 10 one by one into the first carrier 100; at this time, in order to conveniently define the position of the insulating sheet 10, the insulating sheet 10 is laid flat on the first carrier 100, so that the flipping mechanism 200 can accurately take the insulating sheet 10 from the first carrier 100. The flipping mechanism 200 flips one insulating sheet 10 at a time, 90° each time, so that the insulating sheet 10 is flipped from the flat state to the vertical state. The transport mechanism 400 directly extracts the insulating sheet 10 in the vertical state, so that the insulating sheet 10 is directly opposite to the vertically arranged side of the battery cell 20, which is convenient for buckling.

[0027] In order to define the position of the insulating sheet 10, the upper part of the first carrier 100 is recessed to form a groove 110 capable of accommodating the insulating sheet 10. When the insulating sheet 10 is loaded, it is placed in the groove 110, and the side wall of the groove 110 can define the position of the insulating sheet 10, so as to ensure that the insulating sheet 10 placed in the first carrier 100 has a uniform position, so that the flipping mechanism 200 can take the insulating sheet 10 at this position every time.

[0028] Furthermore, in order to facilitate the flap mechanism 200 to take out the insulating sheet 10 from the first carrier 100, a notch 120 is provided on one side of the first carrier 100 close to the flap mechanism 200. Specifically, the notch 120 is provided on one side of the groove 110; after the insulating sheet 10 is placed in the groove 110, it is placed on the notch 120, and a projection exists in the notch 120. In this way, when extracting the insulating sheet 10, the flap mechanism 200 can extend into the notch 120 to directly extract the sheet-shaped insulating sheet 10.

[0029] The flap mechanism 200 includes: a flap extraction member 210 for extracting the insulating sheet 10; a flap driving assembly 220, which is connected to the flap extraction member 210 and can drive the flap extraction member 210 to rotate so that the insulating sheet 10 extracted by the flap extraction member 210 is flipped from a flat state to a vertical state.

[0030] The flap extractor 210 may be a handling member such as a clamping claw or a suction cup, and may obtain the insulating sheet 10 .

[0031] In one embodiment, the flap driving assembly 220 may be a robot, and the flap extractor 210 is disposed at the movable end of the robot. The robot can realize the three-dimensional movement of the flap extractor 210, so that the flap extractor 210 can extract the insulating sheet 10 from the first carrier 100, and at the same time, the flap extractor 210 and the insulating sheet 10 thereon can be turned over, and the flap extractor 210 and the insulating sheet 10 thereon can be driven to transfer to the battery cell 20.

[0032] In another embodiment, specific reference is made to Figure 1-3The flap driving assembly 220 includes: a first flap driving member 221, which is connected to the flap extracting member 210 and can drive the flap extracting member 210 to approach or move away from the first supporting platform 100 in a horizontal direction; a second flap driving member 222, which is connected to the flap extracting member 210 and can drive the flap extracting member 210 to approach or move away from the first supporting platform 100 in a vertical direction; and a third flap driving member 223, which is connected to the flap extracting member 210 and can drive the flap extracting member 210 to rotate.

[0033] The flap extractor 210 can be arranged at the output end of the third flap driver 223, the main body of the third flap driver 223 is arranged at the output end of the first flap driver 221, and the main body of the first flap driver 221 is arranged at the output end of the second flap driver 222. At this time, after an insulating sheet 10 is placed on the first carrier 100, the first flap driver 221 can drive the flap extractor 210 to approach the first carrier 100, so that the flap extractor 210 can approach to extract the insulating sheet 10; after the flap extractor 210 takes the insulating sheet 10, the second flap driver 222 can drive the flap extractor 210 to carry the insulating sheet 10 up, so that the insulating sheet 10 is away from the first carrier 100, leaving space for the insulating sheet 10 to flip; then, the third flap driver 223 drives the flap extractor 210 to rotate, driving the insulating sheet 10 to be flipped from the flat state to the vertical state.

[0034] Of course, the installation methods of the first flap driving member 221, the second flap driving member 222 and the third flap driving member 223 can be interchanged, and all can realize the driving of the flap extracting member 210. The specific installation method is not limited in this application.

[0035] The first flap driving member 221 and the second flap driving member 222 may be linear driving members such as air cylinders and electric cylinders, while the third flap driving member 223 may be a motor.

[0036] The transport mechanism 400 includes: a transport extractor 410 for extracting the insulating sheet 10 ; and a transport drive assembly 420 , which is connected to the transport extractor 410 and can drive the transport extractor 410 to move between the flipping mechanism 200 and the second carrier 300 .

[0037] The transport and extraction member 410 may be a transport member such as a clamp, a suction cup, etc., and can obtain the insulating sheet 10 .

[0038] In a specific embodiment, referring to Figure 1 The flap extractor 210 and the transport extractor 410 are both clamps. The flap extractor 210 can clamp the first side 11 of the insulating sheet 10, while the transport extractor 410 can clamp the second side 12 and the third side 13 of the insulating sheet 10 after it is flipped to a vertical state. Figure 4The first side 11 of the insulating sheet 10 is the side of the insulating sheet 10 facing the flipping mechanism 200 after being placed on the first carrier 100; the second side 12 and the third side 13 are arranged opposite to each other and are connected to the first side 11. After the flipping mechanism 200 flips the insulating sheet 10, the second side 12 and the third side 13 are flipped from being arranged opposite to each other horizontally to being arranged opposite to each other vertically, and the transport and extraction member 410 can clamp the vertical insulating sheet 10.

[0039] More specifically, the transport and extraction member 410 includes: a first clamping plate 411 and a second clamping plate ( Figure 1 In the embodiment, the second clamping plate is blocked by the first clamping plate 411), which can cooperate to realize the extraction of the insulating sheet 10; the clamping driving member 413 can drive the first clamping plate 411 and the second clamping plate to move relative to each other.

[0040] In one embodiment, the first clamping plate 411 and the second clamping plate can be arranged opposite to each other in the vertical direction. When clamping the vertical insulating sheet 10, the clamping driving member 413 is actuated to drive the first clamping plate 411 to move toward the second side 12 and the second clamping plate to move toward the third side 13, and finally clamp the insulating sheet 10.

[0041] In another embodiment, referring to Figure 4 It can be seen that the middle of the insulating sheet 10 is sunken to form a buckle groove 14; at this time, the first clamping plate 411 and the second clamping plate can be set to at least partially extend into the buckle groove 14; when the clamping driving member 413 drives the first clamping plate 411 and the second clamping plate to move back to back, the first clamping plate 411 and the second clamping plate extending into the buckle groove 14 can press against both sides of the buckle groove 14, thereby extracting the insulating sheet 10. At this time, the first clamping plate 411 and the second clamping plate can press against both sides of the buckle groove 14 in the vertical direction, and can also press against both sides of the buckle groove 14 in the horizontal direction, and both can realize the extraction of the insulating sheet 10.

[0042] In this embodiment, further, the first clamping plate 411 and the second clamping plate may both include a first protrusion 414, a second protrusion 415 and a third protrusion 416. When the first clamping plate 411 and the second clamping plate clamp the vertically arranged insulating sheet 10, the third protrusion 416 of the two will extend into the buckle groove 14, and the first protrusion 414 abuts against the second side 12 of the insulating sheet 10, and the second protrusion abuts against the third side 13, thereby better clamping the insulating sheet 10 and supporting the insulating sheet 10, so as to limit the position state of the insulating sheet 10 after being extracted by the transport extraction member 410, and prevent the insulating sheet 10 from being skewed or displaced during the transport process.

[0043] For the transport and extraction member 410 , in order to realize the transport of the insulating sheet 10 , its actions include: approaching the first loading platform 100 and extracting the vertically arranged insulating sheet 10 ; moving from the first loading platform 100 to the second loading platform 300 ; approaching the second loading platform 300 and transporting the insulating sheet 10 to the battery cell 10 .

[0044] To this end, in one embodiment, the transport drive assembly 420 can be a robot, and the transport extraction member 410 is arranged at the movable end of the robot. The robot can realize the three-dimensional movement of the transport extraction member 410, thereby realizing the extraction and transfer of the insulating sheet 10.

[0045] In another embodiment, the transport driving assembly 420 includes: a first transport driving member 421, which is connected to the transport extracting member 410 and can drive the transport extracting member 410 to move in the vertical direction; and a second transport driving member 422, which is connected to the transport extracting member 410 and can drive the transport extracting member 410 to move in the horizontal direction.

[0046] In this embodiment, the transport and extraction member 410 can be arranged at the output end of the first transport driving member 421, and the main body of the first transport driving member 421 can be arranged at the output end of the second transport driving member 422. Alternatively, the transport and extraction member 410 can be arranged at the output end of the second transport driving member 422, and the main body of the second transport driving member 422 can be arranged at the output end of the first transport driving member 421. Both can realize driving the transport and extraction member 410 to move in the vertical direction and the horizontal direction. Among them, the first transport driving member 421 and the second transport driving member 422 can adopt driving components such as electric cylinders and linear modules.

[0047] Specifically, the transport and extraction member 410 is arranged above the flap mechanism 200 and the second carrying platform 300; when extracting the insulating sheet 10, the second transport driving member 422 first drives the transport and extraction member 410 to move above the flap mechanism 200, and the first transport driving member 421 then drives the transport and extraction member 410 to descend, so that the transport and extraction member 410 can clamp the insulating sheet 10; after the transport and extraction member 410 obtains the insulating sheet 10, the flap mechanism 200 releases the insulating sheet 10, so that the first transport driving member 421 can drive the transport and extraction member 410 to rise and move away from the flap mechanism 200 for avoidance; at the same time, the second transport driving member 422 drives the transport and extraction member 410 to move toward the second carrying platform 300; after the transport and extraction member 410 and the insulating sheet 10 it carries move to above the second carrying platform 300, the first transport driving member 421 drives the transport and extraction member 410 to descend again, so that the transport and extraction member 410 can deliver the vertically arranged insulating sheet 10 to the position facing the battery cell 20.

[0048] It can be understood that after the transport and extraction member 410 extracts the insulating sheet 10, the second transport driving member 422 first drives the transport and extraction member 410 to send the insulating sheet 10 to the top of the second carrier 300; the first transport driving member 421 then drives the transport and extraction member 410 to descend, and sends the insulating sheet 10 to the side facing the battery cell 20. In this process, when the insulating sheet 10 is sent to the battery cell 20, it is difficult to ensure that the insulating sheet 10 fits the winding end of the battery cell 20 exactly. In order to buckle the insulating sheet 10 onto the battery cell 20, in one embodiment, a driving mechanism (not shown) can be provided, connected to the second carrier 300, and capable of driving the second carrier 300 to translate, so as to drive the battery cell 20 on the second carrier 300 to move toward the insulating sheet 10, so that the insulating sheet 10 is passively buckled onto the battery cell 20.

[0049] Alternatively, after the transport and extraction member 410 extracts the insulating sheet 10, the second transport driving member 422 first drives the transport and extraction member 410 to send the insulating sheet 10 to the top of the second supporting platform 300, and the first transport driving member 421 then drives the transport and extraction member 410 to descend, and sends the insulating sheet 10 to the side facing the battery cell 20; then, the second transport driving member 422 further drives the transport and extraction member 410 to move horizontally, so that the transport and extraction member 410 pushes the insulating sheet 10 toward the battery cell 20, and finally actively buckles the insulating sheet 10 on the battery cell 20.

[0050] Alternatively, the transport mechanism 400 further includes a buckle drive assembly 430, which is connected to the transport extraction member 410; after the transport drive assembly 420 drives the transport extraction member 410 to reach the battery cell 20, the insulating sheet 10 is facing the winding end of the battery cell 20, and the buckle drive assembly 430 starts and drives the transport extraction member 410 to move toward the battery cell 20, so as to buckle the insulating sheet 10 directly on the battery cell 20. Specifically, after the transport extraction member 410 extracts the insulating sheet 10, the second transport drive member 422 first drives the transport extraction member 410 to send the insulating sheet 10 to the top of the second carrier 300, and the first transport drive member 421 then drives the transport extraction member 410 to descend, and sends the insulating sheet 10 to the side facing the battery cell 20; then, the buckle drive assembly 430 drives the transport extraction member 410 to move toward the battery cell 20, and finally buckles the insulating sheet 10 on the battery cell 20.

[0051] The buckle drive assembly 430 includes a buckle drive member 431 and a buckle guide member 432. Figure 1 The buckle guide 432 extends in the horizontal direction, the transport and extraction member 410 is slidably arranged on the buckle guide 432, and the buckle driving member 431 is connected to the transport and extraction member 410 and can drive the transport and extraction member 410 to move along the buckle guide 432. At the same time, the main body of the buckle driving assembly 430 is arranged at the output end of the transport driving assembly 420.

[0052] The clip driving member 431 may be a driving member such as a cylinder or an electric cylinder; the clip guiding member 432 may be a guiding member such as a guide rail or a guide rod.

[0053] It is easy to understand that when clipping, the position of the battery cell 20 needs to be relatively fixed, so that the conveying mechanism 400 can transfer the insulating sheet 10 to the side opposite to the side of the battery cell 20 to be clipped. To this end, the clipping device also includes a battery cell fixing mechanism 600, which is arranged on one side of the second carrier 300; the battery cell fixing mechanism 600 includes: a fixing member 610 and a fixing driving member 620, and the fixing driving member 620 is connected to the fixing member 610 and can drive the fixing member 610 to approach or move away from the second carrier 300.

[0054] The fixing member 610 may be a member such as a pressure block or a pressure plate that can press against the battery cell 20; the fixing driving member 620 may be a driving member such as a cylinder or an electric cylinder. Figure 1 In the initial state, the fixing member 610 is suspended above the second supporting platform 300; after the battery cell 20 to be clipped is placed on the second supporting platform 300, the fixing driving member 620 drives the fixing member 610 to descend, so that the fixing member 610 presses against the upper surface of the battery cell 20, thereby fixing the position of the battery cell 20 and preventing the battery cell 20 from moving.

[0055] Furthermore, in order to prevent the fixing member 610 from damaging the surface of the battery cell 20 when pressing the battery cell 20, a flexible member 630 is provided on the side of the fixing member 610 close to the second supporting platform 300; when the fixed driving member 620 drives the fixing member 610 to continuously press the battery cell 20, the flexible member 630 is compressed.

[0056] Specifically, the flexible member 630 can be made of flexible materials such as polyurethane and rubber. By pressing the battery cell 20 with the flexible member 630, it is possible to avoid the battery cell 20 being damaged when the fixed member 610 made of a rigid material continuously presses against the battery cell 20. Since the flexible member 630 has a certain deformation amount, when the fixed driving member 620 continuously drives the fixed member 610 to press against the battery cell 20 to compress the battery cell 20, the flexible member 630 is compressed, thereby compensating for the excess stroke output by the fixed driving member 620; at the same time, the flexible member 630 has an elastic restoring force, which can act in the opposite direction on the battery cell 20 to ensure that the fixed member 610 compresses the battery cell 20.

[0057] It should be added that after the insulating sheet 10 is buckled onto the battery cell 20 , the insulating sheet 10 needs to be fixed. At this time, a gluing device (not shown) is provided to gluing the insulating sheet 10 so as to attach the insulating sheet 10 to the battery cell 20 .

[0058] In one embodiment, after the transport mechanism 400 buckles the insulating sheet 10 onto the battery cell 20 , the transport mechanism 400 does not release the insulating sheet 10 temporarily, and the gluing device sticks the tape to the insulating sheet 10 exposed outside the transport mechanism 400 to fix the insulating sheet 10 to the battery cell 20 .

[0059] In a specific embodiment, the transport mechanism 400 uses a clamp, and its first clamp 411 and second clamp part extend into the buckle groove 14 to extract the insulating sheet 10; at this time, the insulating sheet 10 exposed outside the transport mechanism 400 includes three sections, namely a section outside the first clamp 411, a section between the first clamp 411 and the second clamp, and a section outside the second clamp; because the buckle groove 14 is not large, the section of the insulating sheet 10 between the first clamp 411 and the second clamp is relatively narrow; that is, if the tape is only attached to the section of the insulating sheet 10 between the first clamp 411 and the second clamp, the insulating sheet 10 cannot be fixed. Similarly, if the tape is only attached to a section outside the first clamp 411 or a section outside the second clamp, the tape cannot be fixed. If multiple sets of tapes are to be attached, work efficiency will be affected.

[0060] To this end, the clip device also includes a fixing mechanism 500, which is arranged on one side of the second supporting platform 300; the fixing mechanism 500 includes: a fixing piece 510 and a fixing driving piece 520; the fixing driving piece 520 is connected to the fixing piece 510 and can drive the fixing piece 510 to approach or move away from the second supporting platform 300; wherein, after the conveying mechanism 400 conveys the insulating sheet 10 to the battery cell 20, the fixing driving piece 520 drives the fixing piece 510 to move toward the second supporting platform 300, so that the fixing piece 510 presses the insulating sheet 10 on the battery cell 20.

[0061] The fixed piece 510 can be a member such as a pressure plate or a pressure block that can be used to hold the insulating sheet 10. Since the insulating sheet 10 buckled on the side of the battery cell 20 is in a vertical state, the fixed piece 510 also has a side extending in the vertical direction, which can hold the insulating sheet 10. More specifically, the fixed piece 510 includes two pressure plates ( Figure 1 In the embodiment of the present invention, one of the pressing plates is blocked by the other pressing plate, the two clamping plates of the conveying mechanism 400 press against the buckle groove 14, and press the insulating sheet 10 against the battery cell 20, and the two pressing plates of the fixed sheet member 510 correspond to a section of the insulating sheet 10 outside the first clamping plate 411 and a section of the insulating sheet 10 outside the second clamping plate respectively; the fixed sheet driving member 520 drives the fixed sheet member 510 to move toward the second carrier 300, so that the two pressing plates can press the two ends of the insulating sheet 10 exposed outside the conveying mechanism 400, and then fix the insulating sheet 10. Subsequently, the conveying mechanism 400 can loosen the insulating sheet 10 so that the middle section of the insulating sheet 10 is exposed to the outside for gluing.

[0062] It should be added that the wound square battery cell has two winding ends.

[0063] In one embodiment, the buckling device provided in the present application can transport the insulating sheets 10 rotated to a vertical state one by one through the transport mechanism 400, so that after one insulating sheet 10 is buckled onto one winding end of the battery cell 20, the transport mechanism 400 returns to transport another insulating sheet 10, and then buckles the other insulating sheet 10 onto the other winding end of the battery cell 20.

[0064] In order to improve work efficiency, in another embodiment, the transport mechanism 400 may include two groups of transport and extraction components 410, each of which can receive an insulating sheet 10 that has been flipped to a vertical state, and the transport drive component 420 can drive the two groups of transport and extraction components 410 to move toward the second supporting platform 300 to simultaneously transport the two insulating sheets 10 to the battery cell 20.

[0065] At this time, the clip driving member 431 can be an air gripper, and the two groups of transport and extraction members 410 are respectively arranged on one output end of the air gripper. At the same time, the transport driving assembly 420 includes two groups of clip guides 432, and the two groups of clip guides 432 are extended and arranged to point to each other; the two groups of transport and extraction members 410 are respectively slidably connected to one group of clip guides 432; the clip driving member 431 can drive the two groups of transport and extraction members 410 to move closer to or away from each other along their corresponding clip guides 432.

[0066] Specifically, after the insulating sheet 10 is obtained, the two groups of transport and extraction members 410 are at positions away from each other. When the transport driving assembly 420 drives the transport and extraction members 410 to the side of the insulating sheet 10 facing the battery cell 20, the two groups of transport and extraction members 410 are just outside the two winding ends of the battery cell 20. The buckle driving member 431 is started to drive the two groups of transport and extraction members 410 to approach each other, so that the two groups of transport and extraction members 410 are close to their corresponding winding ends, so that the two insulating sheets 10 are buckled on the two winding ends of the battery cell 20 at the same time.

[0067] At this time, the battery cell fixing mechanism 600 is provided with two groups, each corresponding to a winding end of the battery cell 20. After the insulating sheet 10 is buckled onto the winding end by the conveying mechanism 400, the fixing driving member 620 drives the fixing member 610 to move toward its corresponding winding end to press the insulating sheet 10 onto the battery cell 20, and then the conveying mechanism 400 releases the insulating sheet 10 to facilitate the gluing device to fix the insulating sheet 10.

[0068] It should also be added that the insulating sheet 10 has a front side and a back side, the front side is sunken, and after being attached to the winding end of the battery cell 20, it has side edges that can rest on the upper and lower surfaces of the battery cell 20; and the back side is partially sunken to form a buckle groove 14. When the transport mechanism 400 extracts the insulating sheet 10, its clamping plate is close to the back side of the insulating sheet 10.

[0069] At this time, the clip device can also be provided with two first carriers 100, each of which can receive an insulating sheet 10; one of the first carriers 100 receives the insulating sheet 10 facing upward, and the other first carrier 100 receives the insulating sheet 10 facing upward. Figure 1 , a first carrier 100 on the right receives the insulating sheet 10 with the front side facing upward, and a first carrier 100 on the left receives the insulating sheet 10 with the reverse side facing upward; in this way, when the insulating sheets 10 are flipped over, when the flipping mechanism 200 receives the insulating sheet 10 on the right, it rotates 90° counterclockwise so that the front side of the insulating sheet 10 faces the other insulating sheet 10; and when the flipping mechanism 200 receives the insulating sheet 10 on the left, it rotates 90° counterclockwise so that the front side of the insulating sheet 10 faces the other insulating sheet 10; at this time, the flipping mechanism 200 can flip the same angle each time; thus, the front sides of the two insulating sheets 10 face each other, and after the transport mechanism 400 takes the two insulating sheets 10, it can directly move them to the battery cell 20, and make the front sides of the two insulating sheets 10 face their corresponding winding ends.

[0070] Furthermore, in order to facilitate the flipping mechanism 200 to flip the insulating sheets in the two first load platforms 100 , the flipping mechanism 200 also includes a translation drive assembly 230 , which is connected to the flipping extractor 210 and can drive the flipping extractor 210 to move between the two first load platforms 100 .

[0071] In addition, the terms "include" and "have" and any variations thereof are intended to cover non-exclusive inclusions. For example, a process, method, system, product or apparatus comprising a series of steps or components is not limited to the listed steps or components, but may optionally include steps or components not listed, or may optionally include other steps or components inherent to these processes, methods, products or apparatuses.

[0072] The above description is only an embodiment of the present application and does not limit the patent scope of the present application. Any equivalent structure or equivalent process transformation made using the contents of the present application specification and drawings, or directly or indirectly used in other related technical fields, are also included in the patent protection scope of the present application.
