DETAILED DESCRIPTION

[0065] To make the objectives, technical solutions, and advantages of the embodiments of the present application more clear, the technical solutions in the embodiments of the present application will be clearly and completely described below in conjunction with the accompanying drawings of the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments. Generally, the components of the embodiments of the present application described and shown in the drawings herein can be arranged and designed in various different configurations.

[0066] 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 protection, but merely represents selected embodiments of the present application. All other embodiments obtained by persons of ordinary skill in the art based on the embodiments in the present application without creative work are within the scope of protection of the present application.

[0067] It should be noted that, unless there is any conflict, the embodiments and features in the embodiments of this application can be combined with each other.

[0068] 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, it does not need to be further defined or explained in subsequent drawings.

[0069] In the description of the embodiments of the present application, it should be noted that the indicated orientations or positional relationships are based on the orientations or positional relationships shown in the accompanying drawings, or are the orientations or positional relationships in which the product of the application is conventionally placed when in use, or are the orientations or positional relationships conventionally understood by those skilled in the art. These are merely for the convenience of describing the present application and simplifying the description, and are not intended to indicate or imply that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation. Therefore, they should not be construed as limiting the present application. In addition, the terms "first," "second," "third," etc. are used only to distinguish descriptions and should not be construed as indicating or implying relative importance.

[0070] Currently, market developments indicate that power batteries are becoming increasingly widely used. They are not only used in energy storage systems such as hydropower, thermal, wind, and solar power plants, but are also widely used in electric vehicles like electric bicycles, electric motorcycles, and electric vehicles, as well as in military equipment and aerospace. As power battery applications continue to expand, market demand is also growing.

[0071] The battery referred to in the embodiments of this application refers to a single physical module that includes one or more battery cells to provide higher voltage and capacity. For example, the battery referred to in this application may include a battery module or a battery pack. A battery generally includes a casing for enclosing one or more battery cells. The casing can reduce the risk of liquids or other foreign matter affecting the charging or discharging of the battery cells.

[0072] A battery cell includes an end cap assembly, a casing, an electrode assembly, and an insulator. The electrode assembly consists of a positive electrode sheet, a negative electrode sheet, and a separator. A battery cell primarily operates by the movement of metal ions between the positive and negative electrode sheets. The positive electrode sheet includes a positive current collector and a positive active material layer. The positive active material layer is coated on the surface of the positive electrode collector. The uncoated positive electrode collector protrudes from the coated positive electrode collector, and the uncoated positive electrode collector serves as the positive tab. For lithium-ion batteries, for example, the positive electrode current collector can be made of aluminum, and the positive active material can be lithium cobalt oxide, lithium iron phosphate, ternary lithium, or lithium manganese oxide. The negative electrode sheet includes a negative current collector and a negative active material layer. The negative active material layer is coated on the surface of the negative electrode collector. The uncoated negative electrode collector protrudes from the coated negative electrode collector, and the uncoated negative electrode collector serves as the negative tab. The negative electrode current collector can be made of copper, and the negative electrode active material can be carbon or silicon, among others. To ensure that high currents can pass without fusing, multiple positive electrode tabs are stacked together, and multiple negative electrode tabs are stacked together. The separator can be made of materials such as PP (polypropylene) or PE (polyethylene). Furthermore, the electrode assembly can be a wound or laminated structure, although the embodiments of the present application are not limited thereto.

[0073] The housing has an opening, and the end cap assembly is used to seal the opening of the housing. The housing and the end cap assembly together form a space for accommodating the electrode assembly and the insulating member. The insulating member wraps around the periphery of the electrode assembly and is connected to the end cap assembly. The insulating member can insulate and isolate the electrode assembly from the housing. The end cap assembly and the insulating member can be welded, bonded, or otherwise bonded. The insulating member needs to be positioned before being connected to the end cap assembly to ensure a relatively accurate relative positional relationship between the insulating member and the end cap assembly 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 to ensure a good positional relationship between the insulating member and the end cap assembly for easy connection, thereby forming a high-quality connection relationship. However, in the related art, the manufacturing equipment for battery cells positions the insulating member by aligning a locating pin with a locating hole on the insulating member. After the locating pin is inserted into the locating hole, the locating hole and the locating pin have a clearance fit, allowing the insulating member to deviate in any radial direction of the locating hole, reducing the positioning accuracy of the insulating member. As a result, a relatively reasonable relative positional relationship between the insulating member and the end cap assembly cannot be formed, resulting in a reduced connection quality between the insulating member and the end cap assembly.

[0074] Based on the above considerations, in order to alleviate the problem of low connection quality between the insulating part and the end cover assembly due to 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, which 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.

[0075] 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 improving the connection quality between the other parts and the insulating part.

[0076] The positioning device disclosed in the embodiment of the present application can be used for, but is not limited to, positioning insulating members, and can also be used in battery cell manufacturing equipment to produce battery cells.

[0077] For the convenience of description, the following embodiments take the positioning mechanism used in manufacturing battery cells as an example to illustrate the relevant structures.

[0078] 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 is used to clamp an insulating member positioned on the positioning device.

[0079] It should be noted that the term "downstream" in the embodiments of this application refers to the order of production, meaning it comes later in the production sequence, and does not define the spatial position of components. It is understood that the clamping mechanism being located downstream of the positioning device means that the insulating component is first positioned by the positioning device and then clamped to the next station by the clamping mechanism.

[0080] As shown in Figures 1 and 2, in some embodiments, the positioning device 100 is used to position an insulating member 200 (shown in Figure 6), and the insulating member 200 is used to wrap the outer surface of the workpiece. 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.

[0081] Depending on the application scenario of the positioning device 100, the workpiece can vary. For example, the workpiece can be an electrode assembly, with the insulating member 200 wrapped around the outer surface of the electrode assembly to insulate and separate the electrode assembly from the housing, and the insulating member 200 is connected to the end cap assembly. Another example is a housing, with the insulating member 200 wrapped around the outer surface of the housing. When the positioning device 100 is used in battery manufacturing, the workpiece can also be a battery casing, with the insulating member 200 wrapped around the outer surface of the casing.

[0082] The positioning platform 10 is used to support the insulating member 200. The positioning platform 10 can bear part or all of the weight of the insulating member. The positioning platform 10 has a support surface 11, and the support surface 11 is used to place the insulating member 200 so that the positioning platform 10 supports the insulating member 200.

[0083] 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 better matching relationship with other components located at the next station. For example, 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. At the next station, the insulating member 200 is wrapped around the outer surface of the electrode assembly 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 beneficial to improving the connection quality between the end cap assembly and the insulating member 200.

[0084] 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 components, the insulating part 200 and the other components have a better relative position relationship, which is beneficial to improving the connection quality between the other components and the insulating part 200.

[0085] The positioning mechanism 20 may abut against one edge of the insulating member 200 to position the insulating member 200. In other implementations, the positioning mechanism 20 may abut against multiple edges of the insulating member 200 to position the insulating member 200. This allows the multiple edges of the insulating member 200 to have good positioning accuracy. This ensures that when the insulating member 200 is transferred to the next workstation to mate with other components, the insulating member 200 and the other components have a good relative positional relationship, thereby improving the connection quality between the other components and the insulating member 200. "Multiple" refers to two or more.

[0086] 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 .

[0087] By positioning the insulating part 200 by having the positioning mechanism 20 press 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 components, the insulating part 200 and the other components have a better relative position relationship, which is beneficial to improving the connection quality between other components and the insulating part 200.

[0088] As shown in Figures 2, 3, and 4, 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 arranged relatively to each other along the first direction Y. 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.

[0089] The adjustment assembly 23 is used to adjust the distance between the first abutting portion 21 and the second abutting portion 22 along the first direction Y. As shown in FIG2 , in some embodiments, the first abutting portion 21 and the second abutting portion 22 are located on opposite sides of the positioning platform 10 along the first direction Y. When viewed along the direction X perpendicular to the support surface, the first abutting portion 21 and the second abutting portion 22 do not overlap. 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.

[0090] The adjustment 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 adjustment 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.

[0091] In the embodiment where the adjustment assembly 23 drives the first abutting portion 21 and the second abutting portion 22 to move closer to or further away from each other in the first direction Y, a single adjustment assembly 23 can be used to synchronously drive the first abutting portion 21 and the second abutting portion 22 to move closer to or further away from each other, thereby simplifying the structure of the positioning mechanism 20 and reducing manufacturing costs. Alternatively, two adjustment assemblies 23 can be used to separately drive the first abutting portion 21 and the second abutting portion 22 to move along the first direction Y so that the first abutting portion 21 and the second abutting portion 22 move closer to or further away from each other. In this way, 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.

[0092] 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 (shown in FIG6 ) and the second edge 220 (shown in FIG6 ). 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. When the first abutting surface 211 abuts against the first edge 210 and is parallel to the first edge 210, and when the second abutting surface 221 abuts against the second edge 220 and is parallel to the second edge 220, it can be considered that the positioning mechanism 20 has completed the positioning of the insulating member 200. In an embodiment where the first abutment portion 21 and the second abutment portion 22 are respectively arranged on opposite sides of the positioning platform 10, when the first abutment portion 21 and the second abutment portion 22 respectively abut against two opposite edges of the insulating member 200, the first abutment portion 21 can abut against the edge of the positioning platform 10, and the first abutment portion 21 can also be at a distance from the edge of the positioning platform 10, and the second abutment portion 22 can abut against the edge of the positioning platform 10, and the second abutment portion 22 can also be at a distance from the edge of the positioning platform 10.

[0093] It should be noted that the positioning mechanism 20 can position the insulating part 200 by placing the insulating part 200 between the first abutting part 21 and the second abutting part 22 after the distance between the first abutting part 21 and the second abutting part 22 is adjusted, and adjusting the first abutting surface 211 to abut against the first edge 210 and the first abutting surface 211 to be parallel to the first edge 210, and adjusting the second abutting surface 221 to abut against the second edge 220 and the second abutting surface 221 to be parallel to the second edge 220.

[0094] The positioning mechanism 20 can also position the insulating part 200 by first placing the insulating part 200 to be positioned on the positioning platform 10, and placing the insulating part 200 between the first abutting portion 21 and the second abutting portion 22 along the first direction Y. 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 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 part 200 until the first abutting surface 211 abuts 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 part 200.

[0095] 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. 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 applicability.

[0096] Please continue to refer to Figures 2, 3, and 4. In some embodiments, the adjustment assembly 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, and the second connecting seat 232 connects the second abutting portion 22 and the driving member 233. 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.

[0097] The first abutment 21 and the driving member 233 are indirectly connected through the first connecting seat 231, and the second abutment 22 and the driving member 233 are indirectly connected through the second connecting seat 232. The adjustment 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 adjustment component 23, thereby simplifying the structure of the positioning mechanism 20 and reducing manufacturing costs. The adjustment component 23 may include two driving members 233, the two driving members 233 respectively connect the first connecting seat 231 and the second connecting seat 232, and the two driving members 233 respectively drive the first connecting seat 231 and the second connecting seat 232, 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 abutment 21 and the second abutment 22, making the positioning method of the positioning mechanism 20 more flexible.

[0098] The first connecting base 231 and the second connecting base 232 may have various structures. As shown in FIG3 and FIG4 , the first connecting base 231 and the second connecting base 232 are both rod-shaped structures extending along the first direction Y. In other embodiments, the first connecting base 231 and the second connecting base 232 may also be L-shaped. The structures of the first connecting base 231 and the second connecting base 232 may be the same or different.

[0099] The provision of the first connecting seat 231 and the second connecting seat 232 facilitates the transmission of 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 .

[0100] In other embodiments, the adjustment assembly 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 .

[0101] 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 relatively 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.

[0102] The first connecting base 231 and the second connecting base 232 are connected to the first output end and the second output end of the driving member 233 respectively. The driving member 233 can synchronously drive the first connecting base 231 and the second connecting base 232.

[0103] 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.

[0104] 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 .

[0105] In some embodiments, the driving member 233 is a bidirectional cylinder.

[0106] 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.

[0107] 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.

[0108] In other embodiments, the driving member 233 may also be a one-way cylinder, a screw motor, etc.

[0109] As shown in FIG. 2 , 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 .

[0110] When the distance between the first abutting portion 21 and the second abutting portion 22 is closest, as viewed along the direction X perpendicular to the support surface, the first connecting seat 231 and the positioning platform 10 overlap, and the second supporting seat and the positioning platform 10 overlap. When the distance between the first abutting portion 21 and the second abutting portion 22 is farthest, as viewed along the direction X perpendicular to the support surface, 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.

[0111] The first connecting seat 231 and the second connecting seat 232 are both located on the side of the positioning platform 10 away from the supporting surface 11 , which reduces the risk of interference between the adjustment component 23 and the insulating member 200 and helps to improve positioning accuracy.

[0112] In some embodiments, the driving member 233 is also located on the side of the positioning platform 10 away from the support 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.

[0113] As shown in FIG3 and FIG4 , 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.

[0114] 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.

[0115] Only the first abutting portion 21 may be adjustably disposed on the first connecting seat 231 along the first direction Y. Alternatively, only the second abutting portion 22 may be adjustably disposed on the second connecting seat 232 along the first direction Y. Alternatively, the first abutting portion 21 may be adjustably disposed on the first connecting seat 231 along the first direction Y, and the second abutting portion 22 may be adjustably disposed on the second connecting seat 232 along the first direction Y. Figures 3 and 4 illustrate 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.

[0116] 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.

[0117] There are many ways to achieve the first abutting portion 21 being adjustably disposed on the first connecting seat 231 along the first direction Y and the second abutting portion 22 being adjustably disposed on the second connecting seat 232 along the first direction Y.

[0118] For example, as shown in Figures 3 and 4, the first connecting seat 231 is provided with a first slide groove 2311, which extends through the first connecting seat 231 along a direction X perpendicular to the support surface. The second connecting seat 232 is provided with a second slide groove 2321, which extends through the second connecting seat 232 along a direction X perpendicular to the support 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), and a second locking member (not shown).

[0119] 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 by a detachable connection method such as bolts or screws. The first abutting portion 21 can also be connected to the first slider 234 by a non-detachable connection method such as welding or bonding. The first locking member passes through the first sliding 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 position of the first slider 234 relative to the first connecting seat 231 is fixed. 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.

[0120] 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 by a detachable connection method such as bolts or screws. The second abutting portion 22 can also be connected to the second slider 235 by a non-detachable connection method such as welding or 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 connecting seat 232 or release the second slider 235 from the second connecting seat 232. When the second locking member locks the second slider 235 to the second connecting seat 232, the second slider 235 is fixed in position relative to the second connecting seat 232. When the second locking member releases the second slider 235 from the second connecting seat 232, the second slider 235 can move relative to the second connecting seat 232 along the first direction Y, thereby adjusting the position of the second abutting portion 22 in the second connecting seat 232.

[0121] The number of the first chute 2311 and the second chute 2321 can be one or more. As shown in Figures 3 and 4, there are two first chute 2311, which are spaced apart along the second direction Z. There are two second chute 2321, which are spaced apart 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.

[0122] In an embodiment where there are multiple first chute slots 2311, the positioning mechanism 20 may include multiple first locking members, each of which corresponds to the first chute slots 2311. The first locking members pass through the corresponding first chute slots 2311 and are connected to the first slider 234. In an embodiment where there are multiple second chute slots 2321, the positioning mechanism 20 may include multiple second locking members, each of which corresponds to the second chute slots 2321. The second locking members pass through the corresponding second chute slots 2321 and are connected to the second slider 235.

[0123] The first locking member can be a bolt, a screw, etc. The second locking member can be a bolt, a screw, etc. The first locking member and the second locking member can be the same or different.

[0124] As shown in Figures 3, 4 and 5, in some embodiments, the first abutting portion 21 is provided with a first avoidance gap 212 for avoiding the clamping mechanism; and / or, the second abutting 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.

[0125] 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 portions of the edge of the insulating member 200, allowing the clamping mechanism to transfer the insulating member 200 by clamping the exposed edges of the insulating member 200 from the first avoidance notch 212 and the second avoidance notch 222. As shown in FIG6 , the insulating member 200 is placed on the positioning platform 10, with a portion of one edge (first edge 210) of the insulating member 200 in the first direction Y exposed from the first avoidance notch 212, and a portion of the other edge of the insulating member 200 in the first direction Y exposed from the second avoidance notch 222.

[0126] Only the first abutting portion 21 may be provided with the first avoidance notch 212. Alternatively, only the second abutting portion 22 may be provided with the second avoidance notch 222. Alternatively, both the first abutting portion 21 and the second abutting portion 22 may be provided with the first avoidance notch 212 and the second abutting portion 22 may be provided with the second avoidance notch 222. Figures 3, 4, and 5 illustrate the case where both the first abutting portion 21 and the second abutting portion 22 are provided with the first avoidance notch 212 and the second abutting portion 22 are provided with the second avoidance notch 222.

[0127] 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 .

[0128] 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.

[0129] In 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.

[0130] 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.

[0131] The second abutting portion 22 may be 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.

[0132] 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. Figures 3, 4, and 5 illustrate a case where 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.

[0133] By providing a plurality of first avoidance notches 212 and / or a plurality of second avoidance notches 222 , it is possible to enable a plurality of clamping mechanisms to jointly clamp the insulating member 200 , thereby improving the clamping stability.

[0134] As shown in Figures 7 to 10, in some embodiments, along the first direction Y, a first limiting portion 236 is provided on the surface of the first abutting portion 21 facing the second abutting 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 abutting 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 abutting portion 22 facing the first abutting 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 abutting portion 22 in a direction away from the positioning platform 10.

[0135] The surface of the first abutting portion 21 facing the second abutting portion 22 in the first direction Y is a 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. Along the direction X perpendicular to the support surface, the first limiting portion 236 has a first limiting surface facing the support surface 11, and the first limiting surface is used to abut against the insulating member 200 to limit the movement of the insulating member 200 in a direction away from the positioning platform 10. Figures 7 and 9 show the situation where the first abutting portion 21 and the first limiting portion 236 form an L-shaped structure.

[0136] The number of first limiting portions 236 can be one or more. In an embodiment in which there are multiple first limiting portions 236, the multiple first limiting portions 236 are spaced apart along the second direction Z. For example, in an embodiment in which the first abutting portion 21 is provided with first avoidance notches 212, a first limiting portion 236 is provided on both sides of each first avoidance notch 212 along the second direction Z. Thus, at least two first limiting portions 236 can be provided on the first abutting portion 21 provided with the first avoidance notches 212.

[0137] 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. Along the direction X perpendicular to the support surface, the second limiting portion 237 has a second limiting surface 2371 facing the support surface 11. The second limiting surface 2371 is used to abut against the insulating member 200 to limit the movement of the insulating member 200 in a direction away from the positioning platform 10. Figures 8 and 10 show the situation where the second abutting portion 22 and the second limiting portion 237 form an L-shaped structure.

[0138] The number of second limiting portions 237 can be one or more. In an embodiment in which there are multiple second limiting portions 237, the multiple second limiting portions 237 are spaced apart along the second direction Z. For example, in an embodiment in which the second abutting portion 22 is provided with second avoidance notches 222, a second limiting portion 237 is provided on both sides of each second avoidance notch 222 along the second direction Z. Thus, at least two second limiting portions 237 can be provided on the second abutting portion 22 provided with the second avoidance notches 222.

[0139] The first limiting portion 236 may be provided only on the surface of the first abutting portion 21 facing the second abutting portion 22. The second limiting portion 237 may be provided only on the surface of the second abutting portion 22 facing the first abutting portion 21. Alternatively, the first limiting portion 236 may be provided on the surface of the first abutting portion 21 facing the second abutting portion 22, and the second limiting portion 237 may be provided on the surface of the second abutting portion 22 facing the first abutting portion 21. Figures 2 and 4 illustrate a case where the first limiting portion 236 is provided on the surface of the first abutting portion 21 facing the second abutting portion 22, and the second limiting portion 237 is provided on the surface of the second abutting portion 22 facing the first abutting portion 21.

[0140] The first limiting portion 236 and / or the second limiting portion 237 limit the insulating member 200 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.

[0141] As shown in Figures 11 and 12, 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. The correcting mechanism 40 is configured to drive the rotating seat 30 to rotate.

[0142] The positioning platform 10 and the positioning mechanism 20 are both mounted on the rotating base 30. The deviation correction mechanism 40 can be a servo motor, a motor, etc.

[0143] 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 of the insulating member 200 and the workpiece.

[0144] In some embodiments, the rotation axis of the rotating base 30 is perpendicular to the support surface 11 of the positioning platform 10 , and the support surface 11 is used to support the insulating member 200 .

[0145] It can be understood that the extending direction of the rotation axis of the rotating base 30 is parallel to the direction of the treatment support surface 11 .

[0146] The rotation axis of the rotating seat 30 is perpendicular to the support surface 11 of the positioning platform 10. The correction driving rotating seat 30 can effectively 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 of the insulating part 200 and other components.

[0147] As shown in Figure 12, in some embodiments, the positioning device 100 further includes a support member 50, which is located on the side of the positioning platform 10 facing 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 assembly 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 support members 50 can be one or more. In the embodiment where the number of 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, thereby improving the stability of the support members 50 supporting the positioning platform 10. Exemplarily, the number of support members 50 is four, and the four support members 50 are respectively located at the four corners of the rectangle.

[0148] In some embodiments, the positioning device 100 further includes a base 60, to which the deflection correction mechanism 40 is mounted. The base 60 can be located on the side of the rotating base 30 facing away from the positioning platform 10. In embodiments where 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 can be located above the rotating base 30. The provision of the base 60 facilitates the installation of the deflection correction mechanism 40.

[0149] As shown in FIG. 13 , in some embodiments, the positioning device 100 further includes a positioning pin 70 . The positioning pin 70 is disposed on the positioning platform 10 . The positioning pin 70 is configured to cooperate with a positioning hole on the insulating member 200 .

[0150] Positioning pins 70 are mounted on the positioning platform 10 and protrude from the support surface 11. Positioning pins 70 engage with positioning holes in the insulating member 200. Once the positioning pins 70 are inserted into the holes, the insulating member 200 is positioned on the positioning platform 10. After the insulating member 200 is positioned on the positioning platform 10, the positioning mechanism 20 is used to position the two opposing edges of the insulating member 200.

[0151] The number of the positioning pins 70 can be one or more. The positioning pins 70 can be arranged in a one-to-one correspondence with the positioning holes on the insulating member 200.

[0152] The positioning pins 70 can engage with the positioning holes on the insulating member 200 to position the insulating member 200 on the positioning platform 10, thereby improving the accuracy of the placement of the insulating member 200 on the positioning platform 10. In conjunction with the positioning mechanism 20, the positioning accuracy of the insulating member 200 can be further improved. When the insulating member 200 is transferred to the next workstation to mate with other components, the insulating member 200 and the other components maintain a good relative positional relationship, thereby improving the connection quality between the other components and the insulating member 200.

[0153] 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 is used to clamp the insulating member 200 positioned on the positioning device 100 .

[0154] 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 welded to the end cap assembly.

[0155] The positioning device 100 positions the insulating part 200 by positioning it against two opposite edges of the insulating part 200, which can improve the positioning accuracy. Therefore, 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 improving the connection quality between other components and the insulating part 200.

[0156] As shown in FIG14 , the embodiment of the present application further provides a method for positioning an insulating member 200 . The method for positioning the insulating member 200 includes:

[0157] S100, placing the insulating member 200 on the positioning platform 10;

[0158] S200 , positioning the insulating member 200 by having the positioning mechanism 20 abut against at least one edge of the insulating member 200 .

[0159] The insulating member 200 may be placed on the positioning platform 10 first, and then the positioning mechanism 20 is pressed 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.

[0160] Alternatively, the position of the positioning mechanism 20 may be adjusted first, and then the insulating member 200 may be placed on the positioning platform 10 and the position of the insulating member 200 may be adjusted until the positioning mechanism 20 abuts against at least one edge of the insulating member 200. For example, the insulating member 200 may be placed on the positioning platform 10 and the position of the insulating member 200 may be adjusted until the positioning mechanism 20 abuts against two opposite edges of the insulating member 200, thereby positioning the insulating member 200, i.e., first executing S200 and then executing S100.

[0161] 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 components, the insulating part 200 and the other components have a better relative position relationship, which is beneficial to improving the connection quality between the other components and the insulating part 200.

[0162] In some embodiments, before placing the insulating member 200 on the positioning platform 10 , the positioning method of the insulating member 200 further includes:

[0163] 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, which is used to provide the insulating member 200 .

[0164] The feeding device is a device for providing the insulating member 200. In some embodiments, the feeding device may include a feeding cabin in which the insulating member 200 is stored.

[0165] 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 the error of the insulating part 200 to be too large during the placement of the insulating part 200 on the positioning platform 10. 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.

[0166] 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 more accurately on the positioning platform 10.

[0167] In some embodiments, placing the insulating member 200 on the positioning platform 10 includes:

[0168] The insulating member 200 provided by the feeding device is placed on the positioning platform 10 through the transfer mechanism.

[0169] The transfer mechanism can be a robot, a conveyor belt, etc.

[0170] Placing the insulating member 200 provided by the feeding device on the positioning platform 10 by means of a transfer mechanism can save labor costs and improve production efficiency.

[0171] 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:

[0172] 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 an assembly device for assembling the insulating member 200 with a workpiece.

[0173] The assembly device is located downstream of the positioning device 100 and provides the next station for the insulating member 200. For example, during the process of manufacturing a battery cell, the assembly device can be a station for wrapping the insulating member 200 around the outer surface of the electrode assembly, or a station for welding the insulating member 200 to the end cap assembly.

[0174] 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.

[0175] 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 between 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 improving the connection quality between other components and the insulating part 200.

[0176] 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:

[0177] The insulating member 200 on the positioning platform 10 is transferred to an assembling device through a clamping mechanism. The assembling device is used to assemble the insulating member 200 with a workpiece.

[0178] Transferring the insulating member 200 on the positioning platform 10 to the assembly device through the clamping mechanism can save labor costs and improve production efficiency.
