DETAILED DESCRIPTION

[0062] In order to make the purpose, technical solution and advantages of the embodiments of the present application clearer, the technical solution in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are part of the embodiments of the present application, rather than all the embodiments. The components of the embodiments of the present application described and shown in the drawings here can be arranged and designed in various different configurations.

[0063] Therefore, the following detailed description of the embodiments of the present application provided in the accompanying drawings is not intended to limit the scope of the present application for which protection is sought, but merely represents selected embodiments of the present application. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in the field without creative work are within the scope of protection of the present application.

[0064] It should be noted that, in the absence of conflict, the embodiments and features in the embodiments of the present application may be combined with each other.

[0065] It should be noted that similar reference numerals and letters denote similar items in the following drawings, and therefore, once an item is defined in one drawing, further definition and explanation thereof is not required in subsequent drawings.

[0066] In the description of the embodiments of the present application, it should be noted that the indicated orientation or positional relationship is based on the orientation or positional relationship shown in the accompanying drawings, or the orientation or positional relationship in which the product of the application is usually placed when in use, or the orientation or positional relationship commonly understood by those skilled in the art, which is only for the convenience of describing the present application and simplifying the description, and does not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as a limitation on the present application. In addition, the terms "first", "second", "third", etc. are only used to distinguish the description and cannot be understood as indicating or implying relative importance.

[0067] At present, from the perspective of market development, the application of power batteries is becoming more and more extensive. Power batteries are not only used in energy storage power systems such as hydropower, thermal power, wind power and solar power stations, but also widely used in electric vehicles such as electric bicycles, electric motorcycles, electric cars, as well as military equipment and aerospace and other fields. With the continuous expansion of the application field of power batteries, the market demand is also constantly expanding.

[0068] The battery mentioned in the embodiments of the present application refers to a single physical module including one or more battery cells to provide higher voltage and capacity. For example, the battery mentioned in the present application may include a battery module or a battery pack. The battery generally includes a box for encapsulating one or more battery cells. The box can prevent liquid or other foreign matter from affecting the charging or discharging of the battery cells.

[0069] The battery cell includes an end cap assembly, a shell, an electrode assembly and an insulating member. The electrode assembly is composed of a positive electrode sheet, a negative electrode sheet and a separator. The battery cell mainly relies on the movement of metal ions between the positive electrode sheet and the negative electrode sheet to work. The positive electrode sheet includes a positive electrode collector and a positive electrode active material layer. The positive electrode active material layer is coated on the surface of the positive electrode collector. The positive electrode collector not coated with the positive electrode active material layer protrudes from the positive electrode collector coated with the positive electrode active material layer. The positive electrode collector not coated with the positive electrode active material layer serves as a positive electrode ear. Taking lithium-ion batteries as an example, the material of the positive electrode collector can be aluminum, and the positive electrode active material can be lithium cobalt oxide, lithium iron phosphate, ternary lithium or lithium manganese oxide. The negative electrode sheet includes a negative electrode collector and a negative electrode active material layer. The negative electrode active material layer is coated on the surface of the negative electrode collector. The negative electrode collector not coated with the negative electrode active material layer protrudes from the negative electrode collector coated with the negative electrode active material layer. The negative electrode collector not coated with the negative electrode active material layer serves as a negative electrode ear. The material of the negative electrode current collector may be copper, and the negative electrode active material may be carbon or silicon, etc. In order to ensure that a large current can pass without melting, the number of positive electrode ears is multiple and stacked together, and the number of negative electrode ears is multiple and stacked together. The material of the isolation film may be PP (polypropylene) or PE (polyethylene), etc. In addition, the electrode assembly may be a winding structure or a laminated structure, and the embodiments of the present application are not limited thereto.

[0070] The shell has an opening, and the end cap assembly is used to seal the opening of the shell. The shell and the end cap assembly together form a storage space for accommodating the electrode assembly and the insulating member. The insulating member is wrapped around the periphery of the electrode assembly and connected to the end cap assembly. The insulating member can insulate and isolate the electrode assembly and the shell. The end cap assembly and the insulating member can be welded, bonded, etc. The insulating member needs to be positioned before being connected to the end cap assembly so that the insulating member and the end cap assembly have a more accurate relative position relationship when connected. For example, the distance between the edge of the insulating member and the edge of the end cap assembly needs to be controlled within a preset range so that the insulating member and the end cap assembly have a better position relationship for easy connection, thereby forming a high-quality connection relationship. However, in the related art, the manufacturing equipment of the battery cell positions the insulating member by cooperating with the positioning pin and the positioning hole on the insulating member. After the positioning pin is inserted into the positioning hole, due to the clearance between the positioning hole and the positioning pin, the insulating member can be offset along any radial direction of the positioning hole, which reduces the positioning accuracy of the insulating member, thereby resulting in a more reasonable relative position relationship between the insulating member and the end cap assembly, thereby resulting in a reduction in the connection quality between the insulating member and the end cap assembly.

[0071] Based on the above considerations, in order to alleviate the problem of low connection quality between the insulating part and the end cover assembly caused by the low positioning accuracy of the insulating part by the manufacturing equipment of the battery cell, an embodiment of the present application provides a positioning device, the positioning device includes a positioning platform and a positioning mechanism, the positioning platform is used to support the insulating part, and the positioning mechanism is configured to abut against at least one edge of the insulating part to position the insulating part.

[0072] By positioning the insulating part by abutting the positioning mechanism against at least one edge of the insulating part, the positioning accuracy can be improved, so that when the insulating part is transferred to the next workstation to cooperate with other parts, the insulating part and the other parts have a better relative position relationship, which is beneficial to improve the connection quality between other parts and the insulating part.

[0073] The positioning device disclosed in the embodiment of the present application can be used for positioning insulating parts but is not limited to it. It can also be used in battery cell manufacturing equipment to produce battery cells.

[0074] For the convenience of description, the following embodiments take the positioning mechanism used in manufacturing a battery cell as an example to illustrate the relevant structure.

[0075] An embodiment of the present application provides a battery cell manufacturing device, which includes a positioning device and a clamping mechanism (not shown in the figure). The clamping mechanism is arranged downstream of the positioning device, and the clamping mechanism is used to clamp an insulating member positioned on the positioning device.

[0076] It should be noted that the "downstream" mentioned in the embodiments of the present application refers to the order of production, and downstream means the production order is later, and does not limit the spatial position between the components. It can be understood that the clamping mechanism is arranged downstream of the positioning device, which means that the insulating part is first positioned by the positioning device and then clamped to the next station by the clamping mechanism.

[0077] like Figure 1 , Figure 2 As shown, in some embodiments, the positioning device 100 is used to position the insulating member 200 ( Figure 6 As shown in the figure, the insulating member 200 is used to wrap the outer surface of the workpiece, and the positioning device 100 includes a positioning platform 10 and a positioning mechanism 20, the positioning platform 10 is used to support the insulating member 200, and the positioning mechanism 20 is configured to abut against at least one edge of the insulating member 200 to position the insulating member 200.

[0078] Depending on the application scenario of the positioning device 100, the workpiece may be different. For example, the workpiece may refer to an electrode assembly, and the insulating member 200 is wrapped around the outer surface of the electrode assembly to insulate and isolate the electrode assembly and the shell, and the insulating member 200 is connected to the end cap assembly. For another example, the workpiece may be a shell, and the insulating member 200 is wrapped around the outer surface of the shell. When the positioning device 100 is used to manufacture a battery, the workpiece may also be a battery box, and the insulating member 200 is wrapped around the outer surface of the box.

[0079] The positioning platform 10 is used to support the insulating member 200. The positioning platform 10 may bear part or all of the weight of the insulation. The positioning platform 10 has a supporting surface 11, and the supporting surface 11 is used to place the insulating member 200, so that the positioning platform 10 supports the insulating member 200.

[0080] The positioning mechanism 20 is used to abut against at least one edge of the insulating member 200, so that by positioning the edge of the insulating member 200, after the insulating member 200 positioned by the positioning device 100 is clamped to the next station by the clamping mechanism, the insulating member 200 has a good matching relationship with other components located at the next station. Exemplarily, when the insulating member 200 is wrapped around the outer surface of the electrode assembly, the insulating member 200 positioned by the positioning device 100 is transferred to the next station by the clamping mechanism, and then the insulating member 200 is wrapped around the outer surface of the electrode assembly at the next station and connected to the end cap assembly. Therefore, by abutting against at least one edge of the insulating member 200 by the positioning mechanism 20, the insulating member 200 can form a reasonable positional relationship with the end cap assembly after being transferred to the next station, which facilitates the connection between the end cap assembly and the insulating member 200, and is conducive to improving the connection quality between the end cap assembly and the insulating member 200.

[0081] By positioning the insulating part 200 by having the positioning mechanism 20 abut against at least one edge of the insulating part 200, the positioning accuracy can be improved, so that when the insulating part 200 is transferred to the next workstation to cooperate with other parts, the insulating part 200 and the other parts have a better relative position relationship, which is beneficial to improving the connection quality between the other parts and the insulating part 200.

[0082] The positioning mechanism 20 may be against one edge of the insulating member 200 to position the insulating member 200. In other implementations, the positioning mechanism 20 may also be against multiple edges of the insulating member 200 to position the insulating member 200, so that multiple edges of the insulating member 200 have good positioning accuracy, so that when the insulating member 200 is transferred to the next station to cooperate with other components, the insulating member 200 and other components have a good relative position relationship, which is conducive to improving the connection quality of other components and the insulating member 200. Multiple refers to two or more.

[0083] In some embodiments, the positioning mechanism 20 is configured to abut against two opposite edges of the insulating member 200 to position the insulating member 200 .

[0084] By positioning the insulating part 200 by having the positioning mechanism 20 abut against two opposite edges of the insulating part 200, the positioning accuracy can be improved, so that when the insulating part 200 is transferred to the next workstation to cooperate with other parts, the insulating part 200 and the other parts have a better relative position relationship, which is beneficial to improving the connection quality between other parts and the insulating part 200.

[0085] like Figure 2 , Figure 3 , Figure 4 As shown, in some embodiments, the positioning mechanism 20 includes a first abutting portion 21, a second abutting portion 22 and an adjusting component 23. The first abutting portion 21 and the second abutting portion 22 are relatively arranged along the first direction Y, and the first abutting portion 21 and the second abutting portion 22 are configured to abut against two opposite edges of the insulating member 200 respectively. The first abutting portion 21 and the second abutting portion 22 are connected to the adjusting component 23, and the adjusting component 23 is configured to adjust the distance between the first abutting portion 21 and the second abutting portion 22.

[0086] The adjustment component 23 is used to adjust the distance between the first abutting portion 21 and the second abutting portion 22 along the first direction Y. Figure 2 As shown, in some embodiments, the first abutting portion 21 and the second abutting portion 22 are respectively located on opposite sides of the positioning platform 10 along the first direction Y, and the first abutting portion 21 and the second abutting portion 22 do not overlap when viewed along the direction X perpendicular to the support surface. In other embodiments, when viewed along the direction X perpendicular to the support surface, the first abutting portion 21 may overlap with the positioning platform 10, and the second abutting portion 22 may overlap with the positioning platform 10.

[0087] The adjusting component 23 can drive one of the first abutting portion 21 and the second abutting portion 22 to move in the first direction Y toward or away from the other, thereby adjusting the distance between the first abutting portion 21 and the second abutting portion 22 along the first direction Y. The adjusting component 23 can also drive the first abutting portion 21 and the second abutting portion 22 to move toward or away from each other in the first direction Y, thereby adjusting the distance between the first abutting portion 21 and the second abutting portion 22.

[0088] In the embodiment where the adjustment component 23 drives the first abutting portion 21 and the second abutting portion 22 to move closer to or farther from each other in the first direction Y, the first abutting portion 21 and the second abutting portion 22 can be synchronously driven to move closer to or farther from each other by one adjustment component 23, which can simplify the structure of the positioning mechanism 20 and reduce the manufacturing cost. Alternatively, the first abutting portion 21 and the second abutting portion 22 can be driven to move along the first direction Y by two adjustment components 23, respectively, so that the first abutting portion 21 and the second abutting portion 22 move closer to or farther from each other, so that the movement of the first abutting portion 21 and the second abutting portion 22 can be independently controlled, making the positioning method of the positioning mechanism 20 more flexible.

[0089] The first abutting portion 21 has a first abutting surface 211 facing the second abutting portion 22, and the second abutting portion 22 has a second abutting surface 221 facing the first abutting portion 21. The two edges of the insulating member 200 along the first direction Y are defined as the first edge 210 ( Figure 6 ) and a second edge 220 ( Figure 6 ). The first abutting surface 211 is used to abut against the first edge 210, and the second abutting surface 221 is used to abut against the second edge 220. In the case where the first abutting surface 211 abuts against the first edge 210 and the first abutting surface 211 is parallel to the first edge 210, and the second abutting surface 221 abuts against the second edge 220 and the second abutting surface 221 is parallel to the second edge 220, it can be considered that the positioning mechanism 20 completes the positioning of the insulating member 200. In the embodiment where the first abutting portion 21 and the second abutting portion 22 are respectively arranged on two opposite sides of the positioning platform 10, when the first abutting portion 21 and the second abutting portion 22 respectively abut against two opposite edges of the insulating member 200, the first abutting portion 21 can abut against the edge of the positioning platform 10, or the first abutting portion 21 can also have a distance from the edge of the positioning platform 10, and the second abutting portion 22 can abut against the edge of the positioning platform 10, or the second abutting portion 22 can also have a distance from the edge of the positioning platform 10.

[0090] It should be noted that the positioning mechanism 20 can position the insulating part 200 by placing the insulating part 200 between the first abutment portion 21 and the second abutment portion 22 after the distance between the first abutment portion 21 and the second abutment portion 22 is adjusted, and adjusting the first abutment surface 211 to abut against the first edge 210 and the first abutment surface 211 to be parallel to the first edge 210, and adjusting the second abutment surface 221 to abut against the second edge 220 and the second abutment surface 221 to be parallel to the second edge 220.

[0091] The positioning mechanism 20 may also position the insulating member 200 by first placing the insulating member 200 to be positioned on the positioning platform 10, and placing the insulating member 200 between the first abutting portion 21 and the second abutting portion 22 along the first direction Y, and the adjusting component 23 adjusts the distance between the first abutting portion 21 and the second abutting portion 22, so that the distance between the first abutting portion 21 and the second abutting portion 22 gradually decreases. During the adjustment process, the first abutting surface 211 gradually approaches the first edge 210, and the second abutting surface 221 gradually approaches the second edge 220, until the first abutting surface 211 abuts against and is parallel to the first edge 210 and the second abutting surface 221 is parallel to the second edge 220. During this process, the first abutting portion 21 and the second abutting portion 22 continuously adjust the position of the insulating member 200 until the first abutting surface 211 abuts against and is parallel to the first edge 210 and the second abutting surface 221 is parallel to the second edge 220, thereby completing the positioning of the insulating member 200.

[0092] By having the first abutting portion 21 and the second abutting portion 22 abut against two opposite edges of the insulating member 200 respectively, the positioning accuracy can be improved, and the adjusting component 23 can adjust the distance between the first abutting portion 21 and the second abutting portion 22 so that the positioning mechanism 20 can position insulating members 200 of different sizes, with a wider range of applications.

[0093] Please continue to refer to Figure 2 , Figure 3 , Figure 4 In some embodiments, the adjustment component 23 includes a first connecting seat 231, a second connecting seat 232 and a driving member 233, the first connecting seat 231 connects the first abutting portion 21 and the driving member 233, the second connecting seat 232 connects the second abutting portion 22 and the driving member 233, and the driving member 233 is configured to drive at least one of the first connecting seat 231 and the second connecting seat 232 to move along the first direction Y to adjust the distance between the first abutting portion 21 and the second abutting portion 22.

[0094] The first abutting portion 21 and the driving member 233 are indirectly connected through the first connecting seat 231, and the second abutting portion 22 and the driving member 233 are indirectly connected through the second connecting seat 232. The adjusting component 23 may include a driving member 233, and the first connecting seat 231 and the second connecting seat 232 are both connected to the driving member 233. The driving member 233 synchronously drives the first connecting seat 231 and the second connecting seat 232, which can simplify the structure of the adjusting component 23, thereby simplifying the structure of the positioning mechanism 20 and reducing the manufacturing cost. The adjusting component 23 may include two driving members 233, and the two driving members 233 are respectively connected to the first connecting seat 231 and the second connecting seat 232. The two driving members 233 drive the first connecting seat 231 and the second connecting seat 232, respectively, so that the movement of the first connecting seat 231 and the second connecting seat 232 can be independently controlled, thereby independently controlling the movement of the first abutting portion 21 and the second abutting portion 22, so that the positioning method of the positioning mechanism 20 is more flexible.

[0095] The first connection base 231 and the second connection base 232 have various structures, such as Figure 3 , Figure 4 As shown, the first connection seat 231 and the second connection seat 232 are both rod-shaped structures extending along the first direction Y. In other embodiments, the first connection seat 231 and the second connection seat 232 may also be L-shaped. The structures of the first connection seat 231 and the second connection seat 232 may be the same or different.

[0096] The provision of the first connecting seat 231 and the second connecting seat 232 facilitates the transmission of the power of the driving member 233 to the first abutting portion 21 and the second abutting portion 22 to adjust the distance between the first abutting portion 21 and the second abutting portion 22 .

[0097] In some other embodiments, the adjustment component 23 may not be provided with the first connecting seat 231 and the second connecting seat 232 , and the first abutting portion 21 and the second abutting portion 22 are both connected to the driving member 233 .

[0098] In some embodiments, the driving member 233 has a first output end (not shown in the figure) and a second output end (not shown in the figure) arranged opposite to each other, the first connecting seat 231 is connected to the first output end, and the second connecting seat 232 is connected to the second output end, and the driving member 233 is configured to drive the first connecting seat 231 and the second connecting seat 232 to move in opposite directions.

[0099] The first connection base 231 and the second connection base 232 are respectively connected to the first output end and the second output end of the driving member 233 , and the driving member 233 can synchronously drive the first connection base 231 and the second connection base 232 .

[0100] There are many ways to arrange the first output end and the second output end, such as the first output end and the second output end are arranged opposite to each other along the first direction Y, the first output end and the second output end overlap in the first direction Y, etc.

[0101] The driving member 233 drives the first connecting seat 231 and the second connecting seat 232 to move in opposite directions, which can improve the efficiency of adjusting the distance between the first abutting portion 21 and the second abutting portion 22 .

[0102] In some embodiments, the driving member 233 is a bidirectional cylinder.

[0103] The bidirectional cylinder has two piston rods arranged opposite to each other along the first direction Y, and the two piston rods respectively form a first output end and a second output end of the driving member 233 .

[0104] The bidirectional cylinder has two output ends, and can synchronously drive the first connecting seat 231 and the second connecting seat 232, with high driving efficiency.

[0105] In other embodiments, the driving member 233 may also be a one-way cylinder, a screw motor, etc.

[0106] like Figure 2 As shown, in some embodiments, the positioning platform 10 has a support surface 11 for supporting the insulating member 200 ; the first connecting seat 231 and the second connecting seat 232 are both located on a side of the positioning platform 10 away from the support surface 11 .

[0107] When the distance between the first abutting portion 21 and the second abutting portion 22 is the shortest, the first connecting seat 231 and the positioning platform 10 overlap, and the second supporting seat and the positioning platform 10 overlap when viewed along the direction X perpendicular to the supporting surface. When the distance between the first abutting portion 21 and the second abutting portion 22 is the farthest, the first connecting seat 231 and the positioning platform 10 may or may not overlap, and the second supporting seat and the positioning platform 10 may or may not overlap when viewed along the direction X perpendicular to the supporting surface.

[0108] The first connection seat 231 and the second connection seat 232 are both located on the side of the positioning platform 10 away from the support surface 11, which reduces the risk of interference between the adjustment component 23 and the insulating member 200 and is conducive to improving the positioning accuracy.

[0109] In some embodiments, the driving member 233 is also located on the side of the positioning platform 10 away from the supporting surface 11 to facilitate driving the first connecting seat 231 and the second connecting seat 232 and reduce the risk of interference with the insulating member 200, which is conducive to improving positioning accuracy.

[0110] like Figure 3 , Figure 4As shown, in some embodiments, the first abutting portion 21 is adjustably disposed on the first connecting seat 231 along the first direction Y; and / or the second abutting portion 22 is adjustably disposed on the second connecting seat 232 along the first direction Y.

[0111] The first abutting portion 21 can move on the first connecting seat 231 along the first direction Y to adjust the position of the first abutting portion 21 on the first connecting seat 231. The second connecting portion can move on the second connecting seat 232 along the first direction Y to adjust the position of the second abutting portion 22 on the second connecting seat 232.

[0112] Only the first abutting portion 21 may be adjustably disposed on the first connection seat 231 along the first direction Y. Only the second abutting portion 22 may be adjustably disposed on the second connection seat 232 along the first direction Y. Alternatively, the first abutting portion 21 may be adjustably disposed on the first connection seat 231 along the first direction Y, and the second abutting portion 22 may be adjustably disposed on the second connection seat 232 along the first direction Y. Figure 3 , Figure 4 2 shows a situation in which the first abutting portion 21 is adjustably disposed on the first connecting seat 231 along the first direction Y and the second abutting portion 22 is adjustably disposed on the second connecting seat 232 along the first direction Y.

[0113] The first abutment portion 21 is adjustably arranged on the first connecting seat 231 along the first direction Y; and / or the second abutment portion 22 is adjustably arranged on the second connecting seat 232 along the first direction Y, which can increase the adjustment range of the distance between the first abutment portion 21 and the second abutment portion 22, so that the positioning mechanism 20 can position more insulating parts 200 of different sizes, making the positioning device 100 more versatile.

[0114] There are many ways to realize that the first abutting portion 21 is adjustably disposed on the first connecting seat 231 along the first direction Y and the second abutting portion 22 is adjustably disposed on the second connecting seat 232 along the first direction Y.

[0115] For example, Figure 3 , Figure 4 As shown, the first connecting seat 231 is provided with a first slide groove 2311, and the first slide groove 2311 penetrates the first connecting seat 231 along the direction X perpendicular to the supporting surface. The second connecting seat 232 is provided with a second slide groove 2321, and the second slide groove 2321 penetrates the second connecting seat 232 along the direction X perpendicular to the supporting surface. The first slide groove 2311 and the second slide groove 2321 both extend along the first direction Y. The positioning mechanism 20 further includes a first slider 234, a second slider 235, a first locking member (not shown in the figure), and a second locking member (not shown in the figure).

[0116] The first abutting portion 21 is connected to the first slider 234. The first abutting portion 21 can be connected to the first slider 234 in a detachable connection manner such as bolts and screws. The first abutting portion 21 can also be connected to the first slider 234 in a non-detachable connection manner such as welding and bonding. The first locking member passes through the first slide groove 2311 and is connected to the first slider 234. The first locking member is used to lock the first slider 234 to the first connecting seat 231 or release the first slider 234 from the first connecting seat 231. When the first locking member locks the first slider 234 to the first connecting seat 231, the first slider 234 is fixed relative to the first connecting seat 231. When the first locking member releases the first slider 234 from the first connecting seat 231, the first slider 234 can move relative to the first connecting seat 231 along the first direction Y, thereby adjusting the position of the first abutting portion 21 in the first connecting seat 231.

[0117] The second abutting portion 22 is connected to the second slider 235. The second abutting portion 22 can be connected to the second slider 235 in a detachable connection manner such as bolts and screws. The second abutting portion 22 can also be connected to the second slider 235 in a non-detachable connection manner such as welding and bonding. The second locking member passes through the second slide groove 2321 and is connected to the second slider 235. The second locking member is used to lock the second slider 235 to the second connection seat 232 or release the second slider 235 from the second connection seat 232. When the second locking member locks the second slider 235 to the second connection seat 232, the second slider 235 is fixed relative to the second connection seat 232. When the second locking member releases the second slider 235 from the second connection seat 232, the second slider 235 can move relative to the second connection seat 232 along the first direction Y, thereby adjusting the position of the second abutting portion 22 in the second connection seat 232.

[0118] The number of the first chute 2311 and the second chute 2321 can be one or more. Figure 3 , Figure 4 As shown, there are two first slide grooves 2311, which are arranged at intervals along the second direction Z, and there are two second slide grooves 2321, which are arranged at intervals along the second direction Z. The first direction Y is perpendicular to the second direction Z, and the direction X perpendicular to the support surface, the first direction Y, and the second direction Z are perpendicular to each other.

[0119] In the embodiment where the number of first slide grooves 2311 is multiple, the positioning mechanism 20 may include multiple first locking members, the first locking members and the first slide grooves 2311 are arranged in a one-to-one correspondence, and the first locking members pass through the corresponding first slide grooves 2311 and are connected to the first slider 234. In the embodiment where the number of second slide grooves 2321 is multiple, the positioning mechanism 20 may include multiple second locking members, the second locking members and the second slide grooves 2321 are arranged in a one-to-one correspondence, and the second locking members pass through the corresponding second slide grooves 2321 and are connected to the second slider 235.

[0120] The first locking member may be a bolt, a screw, etc. The second locking member may be a bolt, a screw, etc. The first locking member and the second locking member may be the same or different.

[0121] like Figure 3 , Figure 4 , Figure 5 As shown, in some embodiments, the first abutment portion 21 is provided with a first avoidance gap 212 for avoiding the clamping mechanism; and / or, the second abutment portion 22 is provided with a second avoidance gap 222 for avoiding the clamping mechanism, and the clamping mechanism is used to clamp the insulating part 200 placed on the positioning platform 10.

[0122] When the first abutting portion 21 and the second abutting portion 22 respectively abut against two opposite edges of the insulating member 200, the first avoidance notch 212 and the second avoidance notch 222 can expose a portion of the edge of the insulating member 200, so that the clamping mechanism can clamp the exposed edge of the insulating member 200 from the first avoidance notch 212 and the second avoidance notch 222, thereby transferring the insulating member 200. Figure 6 As shown, the insulating member 200 is placed on the positioning platform 10, and a portion of an edge (first edge 210) of the insulating member 200 located in the first direction Y is exposed from the first avoidance gap 212, and a portion of another edge of the insulating member 200 located in the first direction Y is exposed from the second avoidance gap 222.

[0123] Only the first abutting portion 21 may be provided with the first avoidance notch 212. Only the second abutting portion 22 may be provided with the second avoidance notch 222. Alternatively, the first abutting portion 21 may be provided with the first avoidance notch 212, and the second abutting portion 22 may be provided with the second avoidance notch 222. Figure 3 , Figure 4 , Figure 5 2 shows a situation where the first abutting portion 21 is provided with a first avoidance notch 212 and the second abutting portion 22 is provided with a second avoidance notch 222 .

[0124] The provision of the first avoidance notch 212 and the second avoidance notch 222 facilitates the clamping mechanism to clamp the insulating member 200 positioned by the positioning device 100 .

[0125] In some embodiments, the number of the first avoidance gap 212 may be one, and the number of the second avoidance gap 222 may be one.

[0126] In some other embodiments, the first abutting portion 21 is provided with a plurality of first avoidance gaps 212 at intervals; and / or the second abutting portion 22 is provided with a plurality of second avoidance gaps 222 at intervals.

[0127] The first abutting portion 21 may be the only portion where a plurality of first avoidance notches 212 are provided at intervals. The plurality of first avoidance notches 212 are arranged along the second direction Z at intervals.

[0128] The second abutting portion 22 may be the only portion that is provided with a plurality of second avoidance notches 222 at intervals. The plurality of second avoidance notches 222 are arranged along the second direction Z at intervals.

[0129] The first abutting portion 21 may be provided with a plurality of first avoidance notches 212 at intervals, and the second abutting portion 22 may be provided with a plurality of second avoidance notches 222 at intervals. Figure 3 , Figure 4 , Figure 5 FIG. 2 shows a situation in which two first avoidance notches 212 are provided at intervals along the second direction Z on the first abutting portion 21 , and two second avoidance notches 222 are provided at intervals along the second direction Z on the second abutting portion 22 .

[0130] By providing a plurality of first avoidance notches 212 and / or a plurality of second avoidance notches 222 , a plurality of clamping mechanisms can be used to clamp the insulating member 200 together, thereby improving the clamping stability.

[0131] like Figure 7-Figure 10 As shown, in some embodiments, along the first direction Y, a first limiting portion 236 is provided on the surface of the first abutment portion 21 facing the second abutment portion 22, and the first limiting portion 236 is configured to limit the movement of the edge of the insulating member 200 abutting against the first abutment portion 21 in a direction away from the positioning platform 10; and / or, along the first direction Y, a second limiting portion 237 is provided on the surface of the second abutment portion 22 facing the first abutment portion 21, and the second limiting portion 237 is configured to limit the movement of the edge of the insulating member 200 abutting against the second abutment portion 22 in a direction away from the positioning platform 10.

[0132] The surface of the first abutting portion 21 facing the second abutting portion 22 in the first direction Y is the first abutting surface 211. The first limiting portion 236 protrudes from the first abutting surface 211 in a direction close to the second abutting portion 22. The first abutting portion 21 and the first limiting portion 236 can form a T-shape or an L-shape. In the direction X perpendicular to the supporting surface, the first limiting portion 236 has a first limiting surface facing the supporting surface 11, and the first limiting surface is used to abut against the insulating member 200 to limit the insulating member 200 from moving in a direction away from the positioning platform 10. Figure 7 , Fig. 9 FIG. 2 shows a situation where the first abutting portion 21 and the first limiting portion 236 form an L-shaped structure.

[0133] The number of the first limiting portions 236 may be one or more. In the embodiment where the number of the first limiting portions 236 is more than one, the multiple first limiting portions 236 are arranged at intervals along the second direction Z. Exemplarily, in the embodiment where the first abutting portion 21 is provided with the first avoidance notch 212, the first limiting portions 236 are respectively provided on both sides of each first avoidance notch 212 along the second direction Z, and at least two first limiting portions 236 may be provided on the first abutting portion 21 provided with the first avoidance notch 212.

[0134] The surface of the second abutting portion 22 facing the first abutting portion 21 in the first direction Y is a second abutting surface 221. The second limiting portion 237 protrudes from the second abutting surface 221 in a direction close to the first abutting portion 21. The second abutting portion 22 and the second limiting portion 237 can form a T-shape or an L-shape. In the direction X perpendicular to the supporting surface, the second limiting portion 237 has a second limiting surface 2371 facing the supporting surface 11, and the second limiting surface 2371 is used to abut against the insulating member 200 to limit the insulating member 200 from moving in a direction away from the positioning platform 10. Figure 8 , Fig.10 FIG. 2 shows a situation where the second abutting portion 22 and the second limiting portion 237 form an L-shaped structure.

[0135] The number of the second limiting portions 237 may be one or more. In the embodiment where the number of the second limiting portions 237 is more than one, the plurality of second limiting portions 237 are arranged at intervals along the second direction Z. For example, in the embodiment where the second abutting portion 22 is provided with a second avoidance notch 222, each second avoidance notch 222 is provided with a second limiting portion 237 on both sides along the second direction Z, respectively, and then at least two second limiting portions 237 may be provided on the second abutting portion 22 provided with the second avoidance notch 222.

[0136] Only the surface of the first abutting portion 21 facing the second abutting portion 22 may be provided with the first limiting portion 236. Only the surface of the second abutting portion 22 facing the first abutting portion 21 may be provided with the second limiting portion 237. Alternatively, the surface of the first abutting portion 21 facing the second abutting portion 22 may be provided with the first limiting portion 236, and the surface of the second abutting portion 22 facing the first abutting portion 21 may be provided with the second limiting portion 237. Figure 2 , Figure 4 2 shows a situation where the first stopper 236 is provided on the surface of the first abutting portion 21 facing the second abutting portion 22 , and the second stopper 237 is provided on the surface of the second abutting portion 22 facing the first abutting portion 21 .

[0137] The first limiting portion 236 and / or the second limiting portion 237 are provided to limit the insulating member 200 , so as to reduce the risk of the insulating member 200 being separated from the first abutting portion 21 and the second abutting portion 22 , thereby improving the stability of the positioning.

[0138] like Fig.11 , Fig.12 As shown, in some embodiments, the positioning device 100 also includes a rotating seat 30 and a correcting mechanism 40, the positioning platform 10 and the positioning mechanism 20 are connected to the rotating seat 30, the rotating seat 30 is connected to the correcting mechanism 40, and the correcting mechanism 40 is configured to drive the rotating seat 30 to rotate.

[0139] The positioning platform 10 and the positioning mechanism 20 are both mounted on the rotating seat 30. The deviation correction mechanism 40 can be a servo motor, a motor, etc.

[0140] The correction mechanism 40 drives the rotating seat 30 to rotate, thereby driving the positioning platform 10 and the positioning mechanism 20 to rotate, and can adjust the relative positions of the positioning platform 10 and the positioning mechanism 20 and other structures, which is beneficial to improving the matching accuracy between the insulating member 200 and the workpiece.

[0141] In some embodiments, the rotation axis of the rotating seat 30 is perpendicular to the supporting surface 11 of the positioning platform 10 , and the supporting surface 11 is used to support the insulating member 200 .

[0142] It can be understood that the extending direction of the rotation axis of the rotating seat 30 is parallel to the direction of the treatment support surface 11 .

[0143] The rotation axis of the rotating seat 30 is perpendicular to the supporting surface 11 of the positioning platform 10. The deviation correction driving rotating seat 30 can effectively adjust the relative positions of the positioning platform 10 and the positioning mechanism 20 with other structures, which is beneficial to improve the matching accuracy of the insulating member 200 and other components.

[0144] like Fig.12 As shown, in some embodiments, the positioning device 100 also includes a support member 50, and the support member 50 is located on the side of the positioning platform 10 away from the support surface 11. The support member 50 is supported between the rotating seat 30 and the positioning platform 10 so that the rotating seat 30 and the positioning platform 10 are arranged relative to each other along the direction X perpendicular to the support surface. In the embodiment where the adjustment component 23 includes a first connecting seat 231 and a second connecting seat 232, the first connecting seat 231 and the second connecting seat 232 are located between the positioning platform 10 and the rotating seat 30. The number of the support members 50 can be one or more. In the embodiment where the number of the support members 50 is multiple, the multiple support members 50 are arranged at intervals so that the positioning platform 10 is subjected to a more uniform force, so as to improve the stability of the support members 50 supporting the positioning platform 10. Exemplarily, the number of the support members 50 is four, and the four support members 50 are respectively located at the four corners of the rectangle.

[0145] In some embodiments, the positioning device 100 further includes a base 60, and the correction mechanism 40 is installed on the base 60. The base 60 can be located on the side of the rotating base 30 away from the positioning platform 10. In an embodiment in which the direction X perpendicular to the support surface is the up-down direction, the rotating base 30 can be located above the base 60, and the positioning platform 10 is located above the rotating base 30. The arrangement of the base 60 facilitates the installation of the correction mechanism 40.

[0146] like Fig.13 As shown, in some embodiments, the positioning device 100 further includes a positioning pin 70 , which is disposed on the positioning platform 10 , and the positioning pin 70 is configured to cooperate with a positioning hole on the insulating member 200 .

[0147] The positioning pin 70 is disposed on the positioning platform 10 and protrudes from the support surface 11. The positioning pin 70 cooperates with the positioning hole on the insulating member 200, and the positioning pin 70 is inserted into the positioning hole, and then the insulating member 200 is placed on the positioning platform 10. After the insulating member 200 is placed on the positioning platform 10, the two opposite edges of the insulating member 200 are positioned by the positioning mechanism 20.

[0148] The number of the positioning pins 70 may be one or more. The positioning pins 70 may be arranged in a one-to-one correspondence with the positioning holes on the insulating member 200 .

[0149] The positioning pin 70 can cooperate with the positioning hole on the insulating member 200, so as to position the insulating member 200 on the positioning platform 10, and improve the accuracy of placing the insulating member 200 on the positioning platform 10. Cooperating with the positioning mechanism 20 can further improve the positioning accuracy of the insulating member 200, so that when the insulating member 200 is transferred to the next station to cooperate with other components, the insulating member 200 and other components have a good relative position relationship, which is conducive to improving the connection quality between other components and the insulating member 200.

[0150] An embodiment of the present application also provides a battery cell manufacturing device, a clamping mechanism and a positioning device 100 provided in any of the above embodiments, wherein the clamping mechanism is arranged downstream of the positioning device 100 , and the clamping mechanism is used to clamp the insulating member 200 positioned on the positioning device 100 .

[0151] The clamping mechanism is located downstream of the positioning device 100. The clamping mechanism clamps the insulating member 200 positioned by the positioning mechanism 20 of the positioning device 100 and moves it to the next station, where the insulating member 200 is wrapped around the outer surface of the electrode assembly and the insulating member 200 is welded to the end cap assembly.

[0152] The positioning device 100 can improve the positioning accuracy by positioning the insulating part 200 against two opposite edges of the insulating part 200, so that when the clamping mechanism clamps the insulating part 200 and moves it to the next workstation to cooperate with other components (such as the end cover assembly), the insulating part 200 and the other components have a better relative position relationship, which is beneficial to improve the connection quality between other components and the insulating part 200.

[0153] like Fig.14 As shown, the embodiment of the present application further provides a method for positioning an insulating member 200, and the method for positioning the insulating member 200 includes:

[0154] S100, placing the insulating member 200 on the positioning platform 10;

[0155] S200 , positioning the insulating member 200 by abutting the positioning mechanism 20 against at least one edge of the insulating member 200 .

[0156] The insulating member 200 may be placed on the positioning platform 10 first, and then the positioning mechanism 20 abuts against at least one edge of the insulating member 200 to achieve positioning of the insulating member 200, that is, S100 is performed first, and then S200 is performed.

[0157] It is also possible to first adjust the position of the positioning mechanism 20, then place the insulating member 200 on the positioning platform 10 and adjust the position of the insulating member 200 until the positioning mechanism 20 abuts against at least one edge of the insulating member 200. For example, the insulating member 200 is placed on the positioning platform 10 and the position of the insulating member 200 is adjusted until the positioning mechanism 20 abuts against two opposite edges of the insulating member 200, thereby positioning the insulating member 200, that is, first execute S200 and then execute S100.

[0158] By positioning the insulating part 200 by having the positioning mechanism 20 abut against at least one edge of the insulating part 200, the positioning accuracy can be improved, so that when the insulating part 200 is transferred to the next workstation to cooperate with other parts, the insulating part 200 and the other parts have a better relative position relationship, which is beneficial to improving the connection quality between the other parts and the insulating part 200.

[0159] In some embodiments, before placing the insulating member 200 on the positioning platform 10, the positioning method of the insulating member 200 further includes:

[0160] S300 , the positioning platform 10 and the positioning mechanism 20 are rotated by the deviation correction mechanism 40 to adjust the relative positions between the positioning platform 10 and the positioning mechanism 20 and the feeding device, where the feeding device is used to provide the insulating member 200 .

[0161] The feeding device is a device for providing the insulating member 200. In some embodiments, the feeding device may include a feeding cabin, and the insulating member 200 is stored in the feeding cabin.

[0162] Due to assembly errors of the equipment, errors caused by frequent use of the equipment, etc., the positioning platform 10 and the positioning mechanism 20 may be deflected by a certain angle relative to the feeding device. This deflection error may cause excessive error in the process of placing the insulating part 200 on the positioning platform 10, and the insulating part 200 cannot be placed on the positioning platform 10, or even after the insulating part 200 is placed on the positioning platform 10, the positioning mechanism 20 cannot correct the error.

[0163] Therefore, before placing the insulating part 200 on the positioning platform 10, the positioning platform 10 and the positioning mechanism 20 are rotated by the correction mechanism 40 to adjust the relative positions between the positioning platform 10 and the positioning mechanism 20 and the feeding device, so that the insulating part 200 provided by the feeding device can be placed on the positioning platform 10 more accurately.

[0164] In some embodiments, placing the insulating member 200 on the positioning platform 10 includes:

[0165] The insulating member 200 provided by the feeding device is placed on the positioning platform 10 through the transfer mechanism.

[0166] The transfer mechanism can be a robot, a conveyor belt, etc.

[0167] Placing the insulating member 200 provided by the feeding device on the positioning platform 10 through the transfer mechanism can save labor costs and improve production efficiency.

[0168] In some embodiments, after the positioning mechanism 20 abuts against at least one edge of the insulating member 200, the positioning method of the insulating member 200 further includes:

[0169] S400 , the positioning platform 10 and the positioning mechanism 20 are rotated by the deviation correction mechanism 40 to adjust the relative positions between the positioning platform 10 and the positioning mechanism 20 and the assembling device, and the assembling device is used to assemble the insulating member 200 with the workpiece.

[0170] The assembly device is located downstream of the positioning device 100, providing the next station for the insulating member 200. For example, in the process of manufacturing a battery cell, the assembly device can be a station for wrapping the insulating member 200 on the outer surface of the electrode assembly, or a station for welding the insulating member 200 and the end cap assembly.

[0171] Due to assembly errors of the equipment, errors caused by frequent use of the equipment, etc., the positioning platform 10 and the positioning mechanism 20 may be deflected by a certain angle relative to the assembly device. This deflection error may cause the insulating part 200 to be unable to be transferred to the assembly device or there may still be a large error between the insulating part 200 and the workpiece after it is transferred to the assembly device.

[0172] Therefore, after the positioning mechanism 20 is pressed against at least one edge of the insulating part 200, the positioning platform 10 and the positioning mechanism 20 are rotated by the correction mechanism 40 to adjust the relative positions of the positioning platform 10 and the positioning mechanism 20 and the assembly device, so that when the insulating part 200 is transferred to the next workstation to cooperate with other components, the insulating part 200 and the other components have a better relative position relationship, which is beneficial to improve the connection quality between other components and the insulating part 200.

[0173] In some embodiments, after the positioning mechanism 20 abuts against at least one edge of the insulating member 200, the positioning method of the insulating member 200 further includes:

[0174] The insulating member 200 on the positioning platform 10 is transferred to an assembling device through a clamping mechanism, and the assembling device is used to assemble the insulating member 200 with a workpiece.

[0175] The insulating member 200 on the positioning platform 10 is transferred to the assembly device by the clamping mechanism, which can save labor costs and improve production efficiency.

The positioning platform 10 is connected to the rotating seat 30 through a support member 50, and the support member 50 enables the positioning platform 10 and the rotating seat 30 to be arranged relatively spaced in the direction X perpendicular to the support surface.

[0177] The positioning mechanism 20 includes a first abutting portion 21, a second abutting portion 22, a first connecting seat 231, a second connecting seat 232, a driving member 233, a first slider 234, a second slider 235, a first limiting portion 236, and a second limiting portion 237. The first abutting portion 21 and the second abutting portion 22 are arranged on two sides of the positioning platform 10 that are arranged opposite to each other along the first direction Y. The first connecting seat 231 is connected to the first output end of the driving member 233, and the first abutting portion 21 is connected to the first connecting seat 231 through the first slider 234. The first slider 234 is adjustably arranged along the first direction Y with respect to the first connecting seat 231, so that the first abutting portion 21 can be adjusted relative to the first connecting seat 231 along the first direction Y. The second connection seat 232 is connected to the second output end of the driving member 233, and the second abutting portion 22 is connected to the second connection seat 232 through a second slider 235. The second slider 235 is adjustably arranged with respect to the second connection seat 232 along the first direction Y, so that the position of the second abutting portion 22 relative to the second connection seat 232 is adjustable along the first direction Y. The first connection seat 231, the second connection seat 232 and the driving member 233 are arranged between the positioning platform 10 and the rotating seat 30.
