Description

Technical Field

[0001] Embodiments of the present application relate to the field of battery technology, and in particular to a battery cell carrier, a battery cell packaging device, and a battery production line. Background Art

[0002] A battery cell includes an electrode assembly and a tab. Taking a soft-pack battery cell as an example, the electrode assembly is encapsulated in a soft-pack shell, and the tab extends out of the soft-pack shell. In the actual production process, if the tab has been welded to the electrode assembly but the encapsulation has not been completed, the tab may sag under the action of gravity, affecting subsequent processes. Utility Model Content

[0003] In view of this, the embodiments of the present application hope to provide a battery cell carrier, a battery cell packaging device and a battery production line that can reduce the probability of tab droop during the production process of battery cells.

[0004] A first aspect of an embodiment of the present application provides a battery cell carrier, comprising: a support plate for supporting a battery cell; and at least one tab support block movably connected to the support plate to switch between a supporting state and an avoidance state by moving relative to the support plate, wherein in the supporting state, the tab support block supports the tab of the battery cell, and in the avoidance state, the tab support block avoids the tab.

[0005] The battery cell carrier of the embodiment of the present application is provided with a tab support block, so that the tab can be supported during the production process of the battery cell, the probability of sagging during the actual production process can be reduced, and the production efficiency and yield rate of the battery cell can be improved.

[0006] Furthermore, in the present embodiment, the tab support block can switch between a supporting state and an avoiding state. Thus, when it is necessary to perform processes such as packaging that require exposing the tab, it is only necessary to adjust the tab support block to the avoiding state without transferring it to other carriers, which helps to further improve the production efficiency of battery cells.

[0007] In some embodiments, the support plate has at least one accommodating groove, and the accommodating groove forms at least one opening on at least one side end surface of the support plate along a first direction. The tab support block is slidably disposed in the accommodating groove along the first direction, and the first direction intersects with the height direction.

[0008] In this embodiment, the tab support block is received in the receiving groove in the avoidance state, so that the tab can be better avoided, which is convenient for performing operations such as packaging and helps to reduce the volume of the battery cell carrier.

[0009] In some embodiments, there are multiple tab support blocks, and the multiple tab support blocks are configured to be able to switch between the supporting state and the avoiding state synchronously.

[0010] In this embodiment, a plurality of tab support blocks can be switched synchronously between a supporting state and an avoiding state, which helps to quickly adjust the state of each tab support block and further improve production efficiency.

[0011] In some embodiments, the battery cell carrier includes: a base, which is arranged on the bottom side of the support plate, and the support plate is movably connected to the base; a transmission assembly, which transmission connects the pole lug support block to the support plate, so that when the support plate moves relative to the base, it can drive the pole lug support block to move relative to the support plate.

[0012] It can be understood that in the process of performing packaging and other processes, it is usually necessary to apply a force to the battery cell, and the force will be transmitted to the support plate. In the present embodiment, the support plate can move relative to the base, and when the support plate moves relative to the base, it can drive the pole lug support block to move relative to the support plate. This means that in the actual execution of the above process, as the force is applied, the pole lug support block can automatically switch between the supporting state and the avoiding state, thereby eliminating the need to configure a separate control mechanism, power mechanism, etc. for the battery cell carrier to control the pole lug support block to adjust its state, thereby simplifying the structure of the battery cell carrier, reducing costs, and improving the operation efficiency and ease of use of the battery cell carrier.

[0013] In some embodiments, there are multiple tab support blocks, and the transmission assembly is configured to drive the multiple tab support blocks to move synchronously.

[0014] In this embodiment, in addition to realizing the synchronous movement of the pole lug support block and the support plate, the transmission assembly also realizes the synchronous movement between multiple pole lug support blocks. This can further simplify the structure of the battery cell carrier, reduce costs, and improve the movement efficiency and ease of use of the battery cell carrier.

[0015] In some embodiments, the base and the support plate are slidably matched in the height direction, and the battery cell carrier includes: an elastic reset member, which is arranged between the base and the support plate, and the elastic reset member is compressed to generate an elastic force when the support plate moves toward the base, and the elastic force is used to drive the support plate to move away from the base for reset.

[0016] In this embodiment, the elastic reset member can provide elastic force to drive the support plate to reset to the initial position. In this way, after the relevant process is completed, the support plate can be quickly reset, so that the transmission assembly drives the tab support block to quickly move from the avoidance state to the support state, thereby further reducing the suspension time of the tab and reducing the risk of the tab sagging. On the other hand, the elastic reset member also helps to keep the support plate in the initial position during the transportation of the battery cell, that is, to keep the tab support block in the support state.

[0017] In some embodiments, the tab support block and the support plate slide together along a first direction, the first direction intersects with the height direction, and the transmission assembly includes at least one connecting rod, one end of the connecting rod is rotatably connected to the base, and the other end is rotatably connected to the tab support block.

[0018] In this embodiment, a connecting rod is used to realize the transmission between the support plate and the tab support block, so that the structure of the transmission component can be simplified and the cost can be reduced.

[0019] In some embodiments, the transmission assembly further includes: a guide member extending along the first direction; a sliding member slidingly cooperates with the guide member along the first direction, and the tab support block is fixedly connected to the sliding member.

[0020] In this embodiment, a guide member is provided in the transmission assembly to guide the movement of the tab support block relative to the support plate, thereby improving the stability and accuracy of the tab support block sliding between the supporting state and the avoiding state, thereby improving the supporting and avoiding effects.

[0021] In some embodiments, the guide member is a rod-shaped structure, the sliding member includes a mounting seat and a linear bearing mounted on the mounting seat, the tab support block is fixedly connected to the mounting seat, and the linear bearing is slidably connected to the guide member.

[0022] In this embodiment, the sliding cooperation between the lug support block and the guide member is achieved by means of a sliding connection between a linear bearing and a rod-shaped guide member. The advantages of the linear bearing are low cost and high motion accuracy. In this way, the sliding accuracy of the lug support block between the supporting state and the avoiding state can be further improved, thereby improving the supporting and avoiding effects.

[0023] In some embodiments, the transmission assembly also includes at least one limit member, which is arranged on at least one side of the mounting seat along the second direction, and the limit member is slidably matched with the mounting seat, the second direction intersects with the first direction, and the first direction and the second direction are both perpendicular to the height direction.

[0024] In this embodiment, a limit member is provided on at least one side of the mounting seat along the second direction, which helps to maintain the balance of the mounting seat, thereby further improving the stability of the sliding member sliding along the first direction, and further improving the stability of the pole ear support block sliding between the supporting state and the avoidance state, thereby reducing shaking.

[0025] In some embodiments, the support plate has a receiving groove, and the receiving groove forms openings on the opposite side end surfaces of the support plate along the first direction. The number of the pole lug support blocks is two, and the pole lug support blocks are located in the receiving groove. The two pole lug support blocks can extend out of the receiving groove through the two openings respectively. The number of the sliding members is two, and the two pole lug support blocks are respectively fixedly connected to the two sliding members, each of the sliding members is rotatably connected to at least one of the connecting rods, and the two sliding members are both slidably matched with the guide member along the first direction.

[0026] In this embodiment, the battery cell carrier includes two tab support blocks, so that the tabs on the opposite sides of the battery cell along the first direction can be supported simultaneously. The two tab support blocks slide with the same guide member through two sliding members, so that the tab support blocks and the support plate can be linked and the two tab support blocks can move synchronously at a relatively low cost. This structure is relatively small and compact, which helps to miniaturize the battery cell carrier and improve its versatility.

[0027] In some embodiments, the sliding member and the guiding member are both disposed in the receiving groove, the receiving groove forms a mounting opening on the bottom surface of the support plate, and a protruding structure is formed at the bottom of the sliding member, the protruding structure extends out of the receiving groove through the mounting opening and is connected to the connecting rod.

[0028] In this embodiment, the guide member and the sliding member are installed in the receiving groove of the support plate, so as to further improve the compactness of the battery cell carrier structure, facilitate the miniaturization of the battery cell carrier, and improve its versatility.

[0029] In some embodiments, the battery cell carrier includes a mounting plate, which is arranged between the support plate and the base, and the mounting plate has a mounting groove, the top side of the mounting groove is open, and the protruding structure extends into the mounting groove; the transmission assembly also includes a limit member, which is arranged in the mounting groove, and the protruding structure is provided with one limit member on each of the opposite sides along the second direction, and the limit member is slidably matched with the protruding structure, the second direction intersects with the first direction, and the first direction and the second direction are both perpendicular to the height direction.

[0030] In this embodiment, a stopper is provided on each of the two opposite sides of the protruding structure along the second direction, which helps to further improve the sliding stability of the sliding member and reduce the shaking of the tab support block during movement. Furthermore, in this embodiment, the stopper and the protruding structure are provided in the mounting groove of the mounting plate, which helps to protect the protruding structure and the stopper and improve the service life of the battery cell carrier.

[0031] In some embodiments, the limiting member includes at least one follower bearing, and the outer ring of the follower bearing is slidably matched with the protruding structure. In the case where the limiting member includes a plurality of the follower bearings, the plurality of the follower bearings are distributed along the first direction.

[0032] In this embodiment, the position-limiting member includes at least one follower bearing, so that the position-limiting member can have better power transmission and impact resistance performance, thereby improving the sliding accuracy and stability of the sliding member. Further, in an embodiment where the position-limiting member includes multiple follower bearings, the multiple follower bearings are distributed along the first direction, that is, distributed along the sliding direction of the sliding member, so that it is helpful to limit the sliding member during the entire sliding process.

[0033] In some embodiments, the battery cell carrier includes: a pressing plate disposed on the top side of the support plate, wherein the pressing plate can move relative to the support plate in a height direction to clamp the battery cell between the pressing plate and the support plate.

[0034] In this embodiment, a pressure plate is added to the battery cell carrier, and the pressure plate and the support plate can clamp the battery cell, which can improve the position stability of the battery cell during the execution of processes such as packaging and improve the yield rate.

[0035] In some embodiments, the battery cell carrier includes: a connecting shaft extending along the height direction; a connecting member, the pressure plate is connected to the connecting shaft through the connecting member, one of the connecting member and the support plate is fixedly connected to the connecting shaft, and the other is slidingly matched with the connecting shaft along the height direction, one end of the pressure plate is rotatably connected to the connecting member and the rotation axis is perpendicular to the height direction.

[0036] In this embodiment, the pressing plate is slidably matched with the support plate along the height direction with the aid of a connecting piece and a connecting shaft. One end of the pressing plate is rotatably connected to the connecting piece and the rotation axis is perpendicular to the height direction. In this way, during actual use, when the battery cell needs to be placed on the support plate or removed from the support plate, the pressing plate can be operated to rotate in the direction away from the support plate, thereby exposing the support plate and facilitating the battery cell removal and placement operations.

[0037] A second aspect of an embodiment of the present application provides a battery cell packaging device, the battery cell packaging device comprising:

[0038] The battery cell carrier described in the first aspect of the embodiment of the present application; a conveying mechanism for conveying the battery cell carrier; and a packaging mechanism, arranged on the top side of the conveying mechanism, the packaging mechanism can apply a downward pressure force in the height direction to the battery cell placed on the battery cell carrier to encapsulate the battery cell.

[0039] In the battery cell packaging equipment of this embodiment, the battery cell carrier is provided with a tab support block, so that the tab of the battery cell can be supported during the conveying process of the conveying mechanism, reducing the probability of sagging, and improving the production efficiency and yield rate of the battery cell. Further, in this embodiment, the tab support block has a supporting state for supporting the tab and a avoiding state for avoiding the tab, so that in the packaging process, it is only necessary to adjust the tab support block to the avoiding state, without transferring it to other carriers, which helps to further improve the production efficiency of the battery cell.

It may be contact with essentially no interaction force between the two contacting parties, or it may be contact with interaction force between the two contacting parties.

[0057] In the embodiment of the present application, the battery cell may be a secondary battery. A secondary battery refers to a battery cell that can be continuously used by activating active materials by charging after the battery cell is discharged.

[0058] The battery cell can be a lithium ion battery, a sodium ion battery, a sodium lithium ion battery, a lithium metal battery, a sodium metal battery, a lithium sulfur battery, a magnesium ion battery, a nickel hydrogen battery, a nickel cadmium battery, a lead storage battery, etc., which is not limited in the embodiments of the present application.

[0059] A battery cell generally includes an electrode assembly. The electrode assembly includes a positive electrode, a negative electrode, and a separator, which is arranged between the negative electrode and the positive electrode. During the charge and discharge process of the battery cell, active ions (such as lithium ions) are embedded and released back and forth between the positive electrode and the negative electrode. The separator is arranged between the positive electrode and the negative electrode to prevent the positive and negative electrodes from short-circuiting, while allowing active ions to pass through.

[0060] The electrode assembly may be a wound structure, a laminated structure, or a mixed structure of a wound structure and a laminated structure.

[0061] In some embodiments, the electrode assembly is a wound structure, wherein the positive electrode sheet and the negative electrode sheet are wound into a wound structure.

[0062] In some embodiments, the electrode assembly is a laminate structure.

[0063] As an example, a plurality of positive electrode sheets and a plurality of negative electrode sheets may be provided respectively, and the plurality of positive electrode sheets and the plurality of negative electrode sheets may be alternately stacked.

[0064] As an example, a plurality of positive electrode sheets may be provided, and the negative electrode sheet may be folded to form a plurality of stacked folded segments, with a positive electrode sheet being sandwiched between adjacent folded segments.

[0065] As an example, both the positive electrode sheet and the negative electrode sheet are folded to form a plurality of folded sections that are stacked.

[0066] As an example, a plurality of separators may be provided, each of which is provided between any adjacent positive electrode sheets or negative electrode sheets.

[0067] As an example, the separator may be disposed continuously, and may be disposed between any adjacent positive electrode sheets or negative electrode sheets by folding or winding.

[0068] In some embodiments, the shape of the electrode assembly can be cylindrical, flat, or polygonal.

[0069] In some embodiments, the battery cell includes a tab that can conduct current from the electrode assembly. The tab includes a positive tab and a negative tab.

[0070] In some embodiments, the battery cell includes a shell. The shell can be a steel shell, an aluminum shell, a plastic shell (such as polypropylene), a composite metal shell (such as a copper-aluminum composite shell) or an aluminum-plastic film. In some embodiments, the shell can be a sealed structure or a non-sealed structure. As an example, when the shell is a non-sealed structure, the shell plays a role in protecting the electrode assembly, and a sealing bag is also included between the shell and the electrode assembly, and the sealing bag is used to encapsulate the electrode assembly and the electrolyte. Specifically, the sealing bag can be a bag-shaped insulating member or an aluminum-plastic film. When the shell is a sealed structure, it is used to encapsulate components such as the electrode assembly and the electrolyte.

[0071] Taking soft-pack batteries as an example, the outer shell is usually an aluminum-plastic film or other flexible composite films, the electrode assembly is encapsulated in the outer shell, and the tabs extend from the outer shell.

[0072] In the actual production process of battery cells, the tabs are first welded to the electrode assembly, and then subsequent processes such as packaging are carried out. Before the tab welding is completed but the packaging is not completed, the tab may sag due to its own gravity and other reasons, thus affecting the execution of subsequent processes. Especially for soft-pack cells, the tabs are relatively long and have a high probability of sagging, which seriously affects the production efficiency and yield rate of battery cells.

[0073] In view of the above problems, a battery cell carrier according to an embodiment of the present application is proposed. The battery cell carrier is mainly used to carry battery cells when the battery cells are transported between various workstations on a production line and when performing related processes.

[0074] Specifically, the battery cell carrier of the embodiment of the present application includes a support plate and at least one tab support block. The support plate is used to support the battery cell, and the at least one tab support block is movably connected to the support plate to switch between a support state and an avoidance state by moving relative to the support plate, wherein in the support state, the tab support block supports the tab of the battery cell, and in the avoidance state, the tab support block avoids the tab.

[0075] The battery cell carrier of the embodiment of the present application is provided with a tab support block, so that the tab can be supported during the production process of the battery cell, reducing the probability of sagging or interference with other structures during the actual production process, thereby improving the production efficiency and yield rate of the battery cell.

[0076] Furthermore, in the present embodiment, the tab support block can switch between a supporting state and an avoiding state. Thus, when it is necessary to perform processes such as packaging that require exposing the tab, it is only necessary to adjust the tab support block to the avoiding state without transferring it to other carriers, which helps to further improve the production efficiency of battery cells.

[0077] Reference Figure 1-Figure 5 The battery cell carrier of the embodiment of the present application includes a support plate 1 and at least one tab support block 2. The support plate 1 is used to support the battery cell, and the at least one tab support block 2 is movably connected to the support plate 1 to switch between a supporting state and an avoidance state by moving relative to the support plate 1, wherein in the supporting state, the tab support block 2 supports the tab of the battery cell, and in the avoidance state, the tab support block 2 avoids the tab.

[0078] The specific structure of the support plate 1 is not limited, as long as it can support the battery cell. As an example, the shape and size of the support plate 1 can be substantially the same as the outer shell of the battery cell.

[0079] The tab support block 2 is connected to the support plate 1 so that it can form a support on the bottom side of the tab, thereby reducing the probability of the tab sagging under its own gravity.

[0080] The specific structure of the tab support block 2 is not limited, as long as it can effectively support the tab.

[0081] The specific number and location of the tab support blocks 2 are not limited, and those skilled in the art can determine the specific number according to the location and number of tabs of the battery cell that need to be supported. In this embodiment, one tab support block 2 can support one tab, or one tab support block 2 can support multiple tabs at the same time, or multiple tab support blocks 2 can jointly support one tab.

[0082] Taking the most common soft-pack battery cell in the art in which a tab is disposed on each of two opposite sides of the shell as an example, the number of tab support blocks 2 can be at least two, which are disposed on two opposite sides of the support plate 1 along the first direction, so as to simultaneously support two tabs of the soft-pack battery cell. The first direction here intersects with the height direction, and as an example, the first direction is perpendicular to the height direction.

[0083] The tab support block 2 is movably connected to the support plate 1, so that the tab support block 2 can switch between the support state and the avoidance state by moving relative to the support plate 1. Specifically, in the support state, the tab support block 2 moves to the bottom side of the tab and contacts the tab. In the avoidance state, the tab support block 2 can move to other positions (such as inside the support plate 1, the bottom of the support plate 1, etc.), or be removed from the support plate 1.

[0084] The specific manner in which the tab support block 2 is movably connected to the support plate 1 is not limited, such as a sliding connection, a rotating connection, etc.

[0085] During normal transportation, or when performing a process that does not require exposing the tabs, the tab support block 2 can be in a supporting state to support the tabs. When performing a process such as packaging that requires exposing the tabs, the tab support block 2 can be adjusted to an evasive state.

[0086] The battery cell carrier of the embodiment of the present application is provided with a tab support block 2, so that the tab can be supported during the production process of the battery cell, reducing the probability of sagging or interference with other structures during the actual production process, thereby improving the production efficiency and yield rate of the battery cell.

[0087] Furthermore, in the present embodiment, the tab support block 2 can switch between a supporting state and an avoiding state. Thus, when it is necessary to perform processes such as packaging that require exposing the tab, it is only necessary to adjust the tab support block 2 to the avoiding state without transferring it to other carriers, which helps to further improve the production efficiency of battery cells.

[0088] In some embodiments, reference Figure 2-Figure 4 The support plate 1 has at least one receiving groove 11, and the receiving groove 11 forms at least one opening 11a on at least one side end surface of the support plate 1 along the first direction. The tab support block 2 is slidably arranged in the receiving groove 11 along the first direction, and the first direction intersects with the height direction.

[0089] As an example, the first direction is perpendicular to the height direction.

[0090] The support plate 1 may have only one accommodating groove 11 or may have multiple accommodating grooves 11 at the same time. One accommodating groove 11 may accommodate only one tab support block 2 or may accommodate multiple tab support blocks 2 at the same time.

[0091] For one accommodating groove 11 , at least one opening 11 a may be formed only on one end surface of the support plate 1 along the first direction, or at least one opening 11 a may be formed on two opposite end surfaces of the support plate 1 along the first direction.

[0092] Still taking the most common soft-pack battery cell in the field with a pole ear arranged on each opposite side of the shell as an example, the accommodating groove 11 can form an opening 11a on each of the opposite side end surfaces of the support plate 1 along the first direction, and at least two pole ear support blocks 2 are slidably arranged in the accommodating groove 11. In the supporting state, at least two pole ear support blocks 2 extend from the accommodating groove 11 through the openings 11a on the opposite side end surfaces of the support plate 1, thereby supporting the two pole ears.

[0093] In this embodiment, the tab support block 2 can be accommodated in the receiving groove 11 in the avoidance state, so as to better avoid the tab, facilitate packaging and other operations, and help reduce the volume of the battery cell carrier.

[0094] In some embodiments, there are multiple tab support blocks 2 , and the multiple tab support blocks 2 are configured to be able to switch between a supporting state and an avoiding state synchronously.

[0095] In this embodiment, the synchronous switching of multiple tab support blocks 2 between the supporting state and the avoiding state specifically means that when any tab support block 2 switches to the supporting state, the other tab support blocks 2 also switch to the supporting state, and vice versa.

[0096] As an example, a suitable transmission structure can be used to connect multiple tab support blocks 2, so that multiple tab support blocks 2 can act synchronously, thereby realizing synchronous switching between the support state and the avoidance state. Alternatively, multiple tab support blocks 2 can be connected to corresponding drive mechanisms respectively, and each drive mechanism can be interlocked to realize synchronous switching between the support state and the avoidance state.

[0097] In this embodiment, a plurality of tab support blocks 2 can be switched synchronously between a supporting state and an avoiding state, which helps to quickly adjust the state of each tab support block 2 and further improve production efficiency.

[0098] In some embodiments, reference Figure 3 and Figure 4 The battery cell carrier includes: a base 3, which is arranged on the bottom side of the support plate 1, and the support plate 1 is movably connected to the base 3; a transmission component 4, which transmission connects the pole lug support block 2 to the support plate 1, so that when the support plate 1 moves relative to the base 3, it can drive the pole lug support block 2 to move relative to the support plate 1.

[0099] The specific structure of the base 3 is not limited. The base 3 and the support plate 1 can be connected by means of a slide rail, a sliding shaft, an elastic support structure, etc., so that the support plate 1 can move relative to the base 3 in the height direction. Figure 2 and Figure 3 The base 3 may include a top plate 31, a support shaft 32 and a bottom plate 33. The support shaft 32 supports the top plate 31 on the top side of the bottom plate 33 so that the battery cell can be supported at a suitable height.

[0100] The specific movable connection between the support plate 1 and the base 3 is not limited, for example, it can be a sliding connection, a rotating connection, etc.

[0101] The specific structure of the transmission assembly 4 is not limited, such as a connecting rod transmission structure, a gear transmission structure, a gear-rack transmission structure, etc., as long as it can achieve the desired transmission effect.

[0102] It can be understood that in the process of performing packaging and other processes, it is usually necessary to apply a force to the battery cell, and this force will be transmitted to the support plate 1. In the present embodiment, the support plate 1 can move relative to the base 3, and when the support plate 1 moves relative to the base 3, it can drive the pole lug support block 2 to move relative to the support plate 1. This means that in the actual execution of the above process, as the force is applied, the pole lug support block 2 can automatically switch between the supporting state and the avoiding state, thereby eliminating the need to configure a separate control mechanism, power mechanism, etc. for the battery cell carrier to control the pole lug support block 2 to adjust its state, thereby simplifying the structure of the battery cell carrier, reducing costs, and improving the operation efficiency and ease of use of the battery cell carrier.

[0103] In some embodiments, there are multiple tab support blocks 2 , and the transmission assembly 4 is configured to drive the multiple tab support blocks 2 to move synchronously.

[0104] As an example, the transmission assembly 4 may include multiple sub-parts, which respectively drive and connect the multiple tab support blocks 2 with the support plate 1, thereby achieving synchronous movement of the multiple tab support blocks 2. Alternatively, the transmission assembly 4 may include multiple sub-parts, some of which rotatably connect a part of the tab support blocks 2 with the pressure plate 7 and / or the support plate 1, and other sub-parts drive and connect the multiple tab support blocks 2 to each other, thereby achieving synchronous movement of the multiple tab support blocks 2.

[0105] In this embodiment, in addition to realizing the synchronous movement of the pole lug support block 2 and the support plate 1, the transmission assembly 4 also realizes the synchronous movement between multiple pole lug support blocks 2. This can further simplify the structure of the battery cell carrier, reduce costs, and improve the movement efficiency and ease of use of the battery cell carrier.

[0106] In some embodiments, reference Figure 3 The support plate 1 and the base 3 slide together in the height direction. The battery cell carrier includes an elastic reset member 5, which is arranged between the base 3 and the support plate 1. The elastic reset member 5 is compressed when the support plate 1 moves toward the base 3 to generate an elastic force. The elastic force is used to drive the support plate 1 to move away from the base 3 and thus reset to the initial position.

[0107] The specific implementation method of the sliding cooperation between the support plate 1 and the base 3 is not limited.

[0108] The specific structure of the elastic return member 5 is not limited. As an example, the elastic return member 5 may include at least one spring and / or at least one elastic gasket.

[0109] In this embodiment, the support plate 1 can have an initial position (the initial position can be understood as the position of the support plate 1 when not subjected to external force), and the support plate 1 can slide from the initial position along the height direction toward the base 3 under the action of external force. At this time, the elastic return member 5 is compressed to generate an elastic force. After the external force is removed, the support plate 1 can return to the initial position under the elastic force provided by the elastic return member 5.

[0110] Furthermore, in this embodiment, when the support plate 1 is in the initial position, the tab support block 2 can be in the supporting position, and when the support plate 1 slides from the initial position toward the base 3, the transmission assembly 4 drives the support plate 1 to move from the supporting state to the avoiding state.

[0111] In this embodiment, in the relevant process, after the battery cell is subjected to a force in the height direction, the tab support block 2 will be able to automatically move to an evasive state, thereby improving production efficiency.

[0112] Furthermore, the elastic reset member 5 can provide elastic force to drive the support plate 1 to reset, so that after the relevant process is completed, the support plate 1 can be quickly reset, so that the transmission assembly 4 drives the tab support block 2 to quickly move from the avoidance state to the support state, thereby further reducing the suspension time of the tab and reducing the risk of the tab sagging. On the other hand, the elastic reset member 5 also helps to keep the support plate 1 in the initial position during the transportation of the battery cell, that is, to keep the tab support block 2 in the support state.

[0113] In some embodiments, reference Figure 4 The tab support block 2 and the support plate 1 slide together along a first direction, and the first direction intersects with the height direction. The transmission assembly 4 includes at least one connecting rod 41, one end of the connecting rod 41 is rotatably connected to the base 3, and the other end is rotatably connected to the tab support block 2.

[0114] As an example, the first direction is perpendicular to the height direction.

[0115] The specific structure of the connecting rod 41 is not limited. As an example, the connecting rod 41 may be a non-bendable one-piece rod-shaped structure, or the connecting rod 41 may include a plurality of sub-rods rotatably connected to each other. Those skilled in the art may determine the specific structure based on actual usage requirements.

[0116] The rotational connection between the connecting rod 41 and the base 3 specifically means that the connecting rod 41 is connected to the base 3 and can rotate relative to the base 3, and the same is true for the rotational connection between the connecting rod 41 and the tab support block 2. The specific implementation method of the rotational connection between the connecting rod 41 and the above components is not limited, such as direct connection or indirect connection achieved by other intermediate structures.

[0117] Each tab support block 2 may be rotatably connected to only one connecting rod 41 , or may be rotatably connected to multiple connecting rods 41 at the same time, and there is no limitation to this.

[0118] The supporting plate 1 mentioned above includes the receiving groove 11 , and the receiving groove 11 forms an opening 11 a on at least one side end surface of the supporting plate 1 along the first direction.

[0119] Reference Figure 4 The connecting rod 41 can be set as an integral rod-shaped structure that cannot be bent. The connecting rod 41 is inclined from the end close to the base 3 to the end close to the tab support block 2 toward the direction of the opening 11a pointing to the inside of the receiving groove 11. In this way, when the support plate 1 moves toward the base 3, the connecting rod 41 will rotate in the direction of the opening 11a pointing to the receiving groove 11, thereby driving the tab support block 2 to move into the receiving groove 11. When the support plate 1 moves away from the base 3, the connecting rod 41 rotates in the direction of the opening 11a, thereby driving the tab support block 2 to slide out of the receiving groove 11.

[0120] In this embodiment, the connecting rod 41 is used to realize the transmission between the support plate 1 and the tab support block 2, so that the structure of the transmission component 4 can be simplified and the cost can be reduced.

[0121] Of course, in some other embodiments, structures such as gears, racks, pulleys, etc. can also be used to realize the transmission between the support plate 1 and the tab support block 2.

[0122] In some embodiments, still referring to Figure 4 The transmission assembly 4 further includes: a guide member 42 connected to the support plate 1 and extending along the first direction; a sliding member 43 slidingly matched with the guide member 42 along the first direction, and the tab support block 2 is fixedly connected to the sliding member 43.

[0123] In this embodiment, the guide member 42 is used to guide the movement of the sliding member 43 along the first direction, that is, to guide the movement of the tab support block 2 along the first direction.

[0124] The specific structure of the guide member 42 is not limited, for example, it can be a rod-shaped structure or a track structure, etc.

[0125] The specific positional relationship and connection method between the guide member 42 and the support plate 1 are not limited. Taking the support plate 1 having the receiving groove 11 as an example, the guide member 42 can be arranged in the receiving groove 11, or can be arranged on the bottom side of the support plate 1 or in other directions.

[0126] The specific structure of the sliding member 43 is not limited, as long as it can achieve sliding cooperation with the guide member 42 along the first direction. Taking the guide member 42 as a rod-shaped structure as an example, the sliding member 43 can have a through hole along the first direction, and the guide member 42 is inserted into the through hole. Taking the guide member 42 as a track structure as an example, the sliding member 43 can have a structure such as a pulley.

[0127] In this embodiment, a guide member 42 is provided in the transmission assembly 4 to guide the movement of the tab support block 2 relative to the support plate 1, thereby improving the stability and accuracy of the tab support block 2 sliding between the supporting state and the avoiding state, thereby improving the supporting and avoiding effects.

[0128] In some embodiments, the guide member 42 is a rod-shaped structure, the sliding member 43 includes a mounting seat 431 and a linear bearing 432 mounted on the mounting seat 431 , the tab support block 2 is fixedly connected to the mounting seat 431 , and the linear bearing 432 is slidably connected to the guide member 42 .

[0129] The specific structure of the mounting seat 431 is not limited. As an example, the mounting seat 431 can be a block structure and have a through hole. The through hole passes through the mounting seat 431 along the first direction. The linear bearing 432 is installed in the through hole, and the guide member 42 can be passed through the inner ring of the linear bearing 432.

[0130] In this embodiment, the sliding cooperation between the lug support block 2 and the guide member 42 is achieved by means of a sliding connection between the linear bearing 432 and the rod-shaped guide member 42. The advantage of the linear bearing 432 is that it has low cost and high movement accuracy. In this way, the sliding accuracy of the lug support block 2 between the supporting state and the avoiding state can be further improved, thereby improving the supporting and avoiding effects.

[0131] In some embodiments, reference Figure 4 and Figure 5 The transmission assembly 4 also includes at least one limit member 44, which is arranged on at least one side of the mounting seat 431 along the second direction. The limit member 44 slides with the mounting seat 431. The second direction intersects with the first direction, and the first direction and the second direction are both perpendicular to the height direction.

[0132] As an example, the first direction, the second direction and the height direction are perpendicular to each other. Of course, the first direction and the second direction may also only intersect but not be perpendicular.

[0133] The specific structure of the limiting member 44 is not limited. As an example, the limiting member 44 can be a pulley structure, a bearing structure, etc., as long as it can achieve sliding cooperation with the mounting seat 431.

[0134] In this embodiment, a limit member 44 is provided on at least one side of the mounting seat 431 along the second direction, which helps to maintain the balance of the mounting seat 431, thereby further improving the stability of the sliding member 43 sliding along the first direction, and further improving the stability of the pole ear support block 2 sliding between the supporting state and the avoidance state, thereby reducing shaking.

[0135] In some embodiments, reference Figure 3 and Figure 4 The support plate 1 has a receiving groove 11, and the receiving groove 11 forms openings 11a on the opposite side end surfaces of the support plate 1 along the first direction. There are two tab support blocks 2, and the tab support blocks 2 are located in the receiving groove 11, and the two tab support blocks 2 can extend out of the receiving groove 11 through the two openings 11a respectively. There are two sliding members 43, and the two tab support blocks 2 are fixedly connected to the two sliding members 43 respectively, and each sliding member 43 is rotatably connected to at least one connecting rod 41, and the two sliding members 43 are both slidably matched with the guide member 42 along the first direction.

[0136] Taking the guide member 42 as a rod-shaped structure and the sliding member 43 including a mounting seat 431 and a linear bearing 432 as an example, the guide member 42 can pass through the inner rings of the two linear bearings 432 in sequence, thereby achieving sliding cooperation between the guide member 42 and the two sliding members 43 along the first direction.

[0137] In this embodiment, the battery cell carrier includes two tab support blocks 2, so that the tabs on the opposite sides of the battery cell along the first direction can be supported simultaneously. The two tab support blocks 2 slide with the same guide member 42 through two sliding members 43, so that the linkage between the tab support blocks 2 and the support plate 1 and the synchronous movement of the two tab support blocks 2 can be achieved at a relatively low cost, and this structure is relatively small and compact, which helps to achieve the miniaturization of the battery cell carrier and improve its versatility.

[0138] In some embodiments, reference Figure 4 The sliding member 43 and the guiding member 42 are both arranged in the receiving groove 11. The receiving groove 11 forms a mounting opening 11b on the bottom surface of the supporting plate 1. The bottom of the sliding member 43 forms a protruding structure 43a. The protruding structure 43a extends out of the receiving groove 11 through the mounting opening 11b and is connected to the connecting rod 41.

[0139] Taking the sliding member 43 including the mounting seat 431 and the linear bearing 432 as an example, the protruding structure 43a is formed at the bottom of the mounting seat 431. Since the mounting seat 431 will slide along the first direction during actual use, the mounting opening 11b can be configured as a strip hole or a waist hole extending along the first direction to allow the protruding structure 43a to slide therein.

[0140] The specific method of connecting the protruding structure 43a and the connecting rod 41 is not limited. As an example, the protruding structure 43a and the ends of the connecting rod 41 may have pin holes, and the protruding structure 43a and the connecting rod 41 may be rotatably connected by means of a rotating pin.

[0141] In this embodiment, the guide member 42 and the sliding member 43 are installed in the receiving groove 11 of the support plate 1, so as to further improve the compactness of the battery cell carrier structure, facilitate the miniaturization of the battery cell carrier, and improve its versatility.

[0142] In some embodiments, reference Figure 3 and Figure 5 The battery cell carrier includes a mounting plate 6, which is disposed between the support plate 1 and the base 3. The mounting plate 6 has a mounting groove 61, the top side of the mounting groove 61 is open, and the protruding structure 43a extends into the mounting groove 61. The transmission assembly 4 also includes a limiter 44, which is disposed in the mounting groove 61. A limiter 44 is disposed on each of the two opposite sides of the protruding structure 43a along the second direction, and the limiter 44 is slidably matched with the protruding structure 43a. The second direction intersects with the first square, and the first direction and the second direction are both perpendicular to the height direction.

[0143] As an example, the first direction, the second direction, and the third direction are perpendicular to each other.

[0144] The top surface of the mounting plate 6 can be arranged in close contact with the bottom surface of the support plate 1. Of course, the top surface of the mounting plate 6 can also be spaced apart from the bottom surface of the support plate 1. As mentioned above, in some embodiments, the battery cell carrier includes an elastic reset member 5 disposed between the support plate 1 and the base 3. In this embodiment, the elastic reset member 5 can be specifically disposed between the mounting plate 6 and the base 3. The mounting plate 6 can be pressed against the support plate 1 by the elastic force provided by the elastic reset member 5, or the mounting plate 6 can be fixedly connected to the support plate 1.

[0145] In this embodiment, a stopper 44 is provided on opposite sides of the protruding structure 43a along the second direction, which helps to further improve the sliding stability of the sliding member 43 and reduce the shaking of the tab support block 2 during movement. Furthermore, in this embodiment, the stopper 44 and the protruding structure 43a are provided in the mounting groove 61 of the mounting plate 6, which helps to protect the protruding structure 43a and the stopper 44 and improve the service life of the battery cell carrier.

[0146] Of course, in some other embodiments, the mounting plate 6 may not be provided, and the limiting member 44 may be provided in the receiving groove 11 and slidably cooperate with the partial structure of the mounting seat 431 located in the receiving groove 11 .

[0147] In some embodiments, reference Figure 5 The limiting member 44 includes at least one follower bearing 441, and the outer ring of the follower bearing 441 is slidably matched with the protruding structure 43a. In the case where the limiting member 44 includes multiple follower bearings 441, the multiple follower bearings 441 are distributed along the first direction.

[0148] The specific structure of the follower bearing 441 can refer to the relevant technology in the field, and will not be repeated here. As an example, the follower bearing 441 can specifically include an inner ring, an outer ring, a rolling element and a cage, the cage can be fixedly connected to the inner wall of the mounting groove 61, and the outer ring is slidably matched with the outer surface of the protruding structure 43a.

[0149] In this embodiment, the position-limiting member 44 includes at least one follower bearing 441, so that the position-limiting member 44 can have better power transmission and impact resistance performance, thereby improving the sliding accuracy and stability of the sliding member 43. Further, in the embodiment where the position-limiting member 44 includes multiple follower bearings 441, the multiple follower bearings 441 are distributed along the first direction, that is, distributed along the sliding direction of the sliding member 43, so that it is helpful to limit the sliding member 43 during the entire sliding process.

[0150] In some embodiments, reference Figure 2 and Figure 3The battery cell carrier includes a pressing plate 7 which is disposed on the top side of the support plate 1 and slides with the support plate 1 in the height direction so that the battery cell can be clamped between the pressing plate 7 and the support plate 1 .

[0151] The specific structure of the pressing plate 7 is not limited, and the specific way of sliding cooperation with the support plate 1 in the height direction is not limited. The pressing plate 7 can be configured to slide toward the support plate 1 under its own gravity, or it can be configured to have a certain damping so that it can only slide toward the support plate 1 when it is acted upon by an external force (such as when it is pressed downward by the packaging mechanism), and there is no limitation on this.

[0152] In some of the embodiments described above, the support plate 1 and the base 3 slide together in the height direction. In this embodiment, taking the packaging process as an example, the packaging mechanism first contacts the pressure plate 7, causing the pressure plate 7 to slide toward the support plate 1 to clamp the battery cell, and then, the pressure plate 7, the battery cell and the support plate 1 will move toward the base 3 together under the downward pressure.

[0153] In this embodiment, a pressing plate 7 is added to the battery cell carrier. The pressing plate 7 and the supporting plate 1 can clamp the battery cell, which can improve the position stability of the battery cell during the execution of processes such as packaging and improve the yield rate.

[0154] In some embodiments, still referring to Figure 2 and Figure 3 The battery cell carrier includes: a connecting shaft 8 extending in the height direction. A connecting member 9, a pressing plate 7 is connected to the connecting shaft 8 through the connecting member 9, one of the connecting member 9 and the supporting plate 1 is fixedly connected to the connecting shaft 8, and the other is slidably matched with the connecting shaft 8 in the height direction, and one end of the pressing plate 7 is rotatably connected to the connecting member 9 and the rotation axis is perpendicular to the height direction.

[0155] In this embodiment, the specific number of connecting shafts 8 is not limited, and can be one, two, three, etc. Those skilled in the art can make specific settings according to actual usage requirements to ensure smooth sliding of the pressure plate 7 and / or the support plate 1 as much as possible.

[0156] The connection between the connecting shaft 8 and the pressing plate 7 and / or the supporting plate 1 may be a direct connection or an indirect connection achieved through an intermediate structure. For example, in some embodiments described above, the battery cell carrier includes a mounting plate 6. In such an embodiment, the connecting shaft 8 may be connected to the mounting plate 6, thereby achieving an indirect connection with the supporting plate 1.

[0157] In the embodiment where the tab support block 2 is disposed on one side of the support plate 1 along the first direction, the connecting shaft 8 may be disposed on one side of the pressure plate 7 and the support plate 1 along the second direction so as to avoid the tab support block 2 .

[0158] When there are multiple connecting shafts 8, the multiple connecting shafts 8 can be arranged on the same side of the pressure plate 7 and the support plate 1, for example, on one side along the second direction, or the multiple connecting shafts 8 can be respectively arranged on different sides of the pressure plate 7 and the support plate 1, for example, on opposite sides of the pressure plate 7 and the support plate 1 along the second direction.

[0159] In some embodiments, the connecting shaft 8 may have an elastic portion. When the pressing plate 7 slides toward the support plate 1, the elastic portion is compressed to generate an elastic force. The elastic force is used to drive the pressing plate 7 to move in a direction away from the support plate 1. In this way, during actual use, when the relevant process is completed, the pressing plate 7 and the support plate 1 can automatically pop open under the elastic force provided by the elastic portion to release the battery cell.

[0160] The specific structure of the connecting member 9 is not limited. In the case where there are multiple connecting shafts 8, the connecting members 9 can be arranged one-to-one with the connecting shafts 8, or one connecting member 9 can be connected to multiple connecting shafts 8.

[0161] In this embodiment, the pressing plate 7 is slidably matched with the support plate 1 along the height direction by means of the connecting member 9 and the connecting shaft 8. One end of the pressing plate 7 is rotatably connected to the connecting member 9 and the rotation axis is perpendicular to the height direction. In this way, in actual use, when the battery cell needs to be placed on the support plate 1 or removed from the support plate 1, the pressing plate 7 can be operated to rotate in the direction away from the support plate 1, thereby exposing the support plate 1, which is convenient for performing the battery cell removal operation.

[0162] The battery cell carrier involved in one or more of the above embodiments will be described in more detail and detail below in conjunction with a specific embodiment.

[0163] Reference Figure 1-Figure 5 The battery cell carrier of this embodiment includes a support plate 1 and two tab support blocks 2. The two tab support blocks 2 are arranged on opposite sides of the support plate 1 along a first direction, and the first direction is perpendicular to the height direction.

[0164] The tab support block 2 has a supporting state for supporting the tab and a avoiding state for avoiding the tab. The tab support block 2 is movably connected to the support plate 1, so as to switch between the supporting state and the avoiding state by moving relative to the support plate 1.

[0165] Specifically, the support plate 1 has a receiving groove 11, and the receiving groove 11 forms an opening 11a on both opposite sides of the support plate 1 along the first direction. In the supporting state, the pole lug support block 2 is located in the receiving groove 11. In the avoiding state, the two pole lug support blocks 2 extend from the receiving groove 11 respectively through the above two openings 11a.

[0166] The battery cell carrier also includes a base 3 and a transmission assembly 4. The base 3 is arranged on the bottom side of the support plate 1. The support plate 1 and the base 3 are slidably matched in the height direction. The transmission assembly 4 transmits and connects the tab support block 2 to the support plate 1. The support plate 1 has an initial position. In the initial position, the support plate 1 and the base 3 form a gap and the tab support block 2 is in a supporting state. When the support plate 1 moves from the initial position toward the base 3, the transmission assembly 4 drives the tab support block 2 to move from the supporting state to the avoiding state.

[0167] The transmission assembly 4 specifically includes two connecting rods 41, two sliding members 43 and a guide member 42. The guide member 42 and the two sliding members 43 are both arranged in the receiving groove 11, the guide member 42 extends along the first direction, the sliding member 43 and the guide member 42 slide together along the first direction, the two tab support blocks 2 are respectively fixedly connected to the two sliding members 43, one end of the connecting rod 41 is rotatably connected to the base 3, and the other end is slidably connected to the sliding member 43, so as to realize the transmission connection between the tab support block 2 and the support plate 1.

[0168] The sliding member 43 specifically includes a mounting seat 431 and a linear bearing 432 mounted on the mounting seat 431 . The guide member 42 is a rod-shaped structure and is passed through the inner ring of the linear bearing 432 . The tab support block 2 is fixedly connected to the mounting seat 431 .

[0169] The battery cell carrier further includes a mounting plate 6, which is disposed on the bottom side of the support plate 1 and is disposed in close contact with the support plate 1. The mounting plate 6 has a mounting groove 61, the top side of which is open, the receiving groove 11 forms a mounting opening 11b on the bottom surface of the support plate 1, the bottom of the sliding member 43 (mounting seat 431) has a protruding structure 43a, the protruding structure 43a extends into the mounting groove 61 through the mounting opening 11b, and the connecting rod 41 is connected to the protruding structure 43a.

[0170] The transmission assembly 4 also includes a limit member 44 arranged in the installation groove 61, and a limit member 44 is arranged on the opposite sides of the protruding structure 43a of each sliding member 43 along the second direction. Each limit member 44 includes a plurality of follower bearings 441 distributed along the first direction, and the outer ring of the follower bearing 441 is slidably matched with the protruding structure 43a of the sliding member 43 along the first direction.

[0171] The battery cell carrier also includes an elastic reset member 5, which is arranged between the mounting plate 6 and the base 3. When the support plate 1 and the mounting plate 6 move toward the base 3, the elastic reset member 5 is compressed to generate an elastic force, which is used to drive the support plate 1 and the mounting plate 6 to move in a direction away from the base 3 so as to reset to the initial position.

[0172] The battery cell carrier further includes a pressing plate 7 , which is arranged to slide on the supporting plate 1 along the height direction.

[0173] Specifically, the battery cell carrier includes at least one connecting shaft 8 extending in the height direction, and a connecting member 9, the connecting member 9 is connected to the connecting shaft 8, one of the connecting member 9 and the support plate 1 is fixedly connected to the connecting shaft 8, and the other is slidably matched with the connecting shaft 8 in the height direction.

[0174] One end of the pressing plate 7 is rotatably connected to the connecting member 9 and the rotation axis is perpendicular to the height direction, so that the pressing plate 7 can rotate away from the supporting plate 1 to provide operating space for taking and placing the battery cells.

[0175] The specific usage of the battery cell carrier of this embodiment will be introduced below by taking the packaging of a battery cell as an example.

[0176] First, the pressing plate 7 is rotated away from the supporting plate 1 , the battery cell is placed on the supporting plate 1 , and then the pressing plate 7 is rotated toward the supporting plate 1 .

[0177] Then, the battery cell carrier is transported to the packaging mechanism. During the transportation process, the support plate 1 is in the initial position and the tab support block 2 is in a supporting state.

[0178] Next, the packaging mechanism is controlled to apply a downward pressure, and the packaging mechanism first contacts the pressing plate 7, pressing the pressing plate 7 downward so that the battery cell is clamped between the pressing plate 7 and the support plate 1, and then the packaging mechanism continues to apply a downward pressure, and the pressing plate 7, the battery cell and the support plate 1 move toward the base 3 together. During this process, the tab support block 2 moves from a supporting state to an evasive state. After the support plate 1 moves to the bottom, the tab support block 2 moves to an evasive state, and the tab is exposed. At this time, the packaging can be completed by continuing to control the packaging mechanism to apply a downward pressure.

[0179] After packaging is completed, the packaging mechanism is retracted, and the support plate 1 rebounds to the initial position under the action of the elastic reset member 5, and the tab support block 2 returns to the supporting state and can continue to be transported to the next station for subsequent processing.

[0180] An embodiment of the present application also provides a battery cell packaging device, comprising: a battery cell carrier as described in any of the above embodiments, a conveying mechanism for conveying the battery cell carrier, and a packaging mechanism, arranged on the top side of the conveying mechanism, for packaging battery cells, the packaging mechanism being capable of applying a downward pressure force in the height direction to the battery cells placed in the battery cell carrier to encapsulate the battery cells.

[0181] In this embodiment, the specific structural forms of the conveying mechanism and the packaging mechanism are not limited. As an example, the conveying mechanism can be a conveyor belt, a conveyor vehicle, a conveyor track, etc. The packaging mechanism can include a downward pressure electric cylinder and a head, and the downward pressure electric cylinder can drive the head to move toward the battery cell carrier in the height direction, thereby applying a downward pressure force to the battery cell placed in the battery cell carrier.

[0182] In the battery cell packaging equipment of this embodiment, the battery cell carrier is provided with a tab support block 2, so that the tab of the battery cell can be supported during the conveying process of the conveying mechanism, reducing the probability of sagging, and improving the production efficiency and yield rate of the battery cell. Further, in this embodiment, the tab support block 2 has a supporting state for supporting the tab and a avoiding state for avoiding the tab, so that in the packaging process, it is only necessary to adjust the tab support block 2 to the avoiding state, and there is no need to transfer it to other carriers to complete it, which helps to further improve the production efficiency of the battery cell.
