[0039] In order to understand the embodiments of the present application more clearly, the following Figures 1 to 8 The embodiments of the present application are described in detail.

[0040] like Figures 1 to 8 As shown, the present application provides a correction device 1 for correcting the deviation of a battery 2. A tab 21 is provided at one end of the battery 2. The correction device 1 includes a limiting assembly 11 and a clamping assembly 12. The limiting assembly 11 includes a first limiting portion 111 and a second limiting portion 112 spaced apart along a first direction X, with a limiting portion 113 formed between the first limiting portion 111 and the second limiting portion 112 to accommodate the tab 21. The clamping assembly 12 clamps the tab 21 along a second direction Y to correct the rotation of the battery 2. The second direction Y is perpendicular to the first direction X.

[0041] The limiting assembly 11 includes a first limiting portion 111 and a second limiting portion 112 spaced apart along the first direction X, that is, the first limiting portion 111 and the second limiting portion 112 are respectively located on both sides of the tab 21 along the first direction X, thereby limiting the movement of the tab 21 along the first direction X.

[0042] In some embodiments, the shape of the ends of the first limiting portion 111 and the second limiting portion 112 near the tab 21 corresponds to the shape of the tab 21 to ensure that the accommodation space of the formed limiting portion 113 is consistent with the shape of the tab 21, thereby ensuring the limiting effect. In other embodiments, the ends of the first limiting portion 111 and the second limiting portion 112 are provided with extensions extending along the extension direction of the tab 21, and the limiting portion 113 is formed between the two extensions. The tab 21 is accommodated between the extensions to increase the space of the limiting portion 113 along the extension direction of the tab, increase the contact area between the limiting portion 113 and the tab 21, and improve the limiting effect.

[0043] In some embodiments, the clamping assembly 12 may be a mechanical clamp that, driven by the second drive assembly 162, clamps or releases the tab 21 in the second direction Y. Specifically, the clamping assembly includes a first clamping jaw and a second clamping jaw spaced apart along the second direction, and at least one of the first clamping jaw and the second clamping jaw can move along the second direction Y to clamp or release the tab 21. Similarly, the shapes of the ends of the first clamping jaw and the second clamping jaw near the tab 21 correspond to the shape of the tab 21 along the second direction to ensure that the tab 21 can be clamped in the clamping assembly.

[0044] By setting the limit component 11, the movement of the tab 21 in the first direction X can be limited, and then the tab 21 can be clamped from the second direction Y by the clamping component 12 so that the tab 21 can be corrected. At the same time, the battery 2 rotates and corrects along with the tab 21, completing the correction of the tab 21 and the battery 2.

[0045] like Figure 1 、 3 As shown in Figures 5 and 5, in some embodiments, the correcting device 1 further includes a first base 13 and a second base 14 spaced apart along the first direction X, the first limiting portion 111 and the clamping assembly 12 are arranged on the first base 13, and the second limiting portion 112 is arranged on the second base 14.

[0046] The first base 13 and the second base 14 are components fixedly connected to the frame or the bottom surface. The shapes and materials of the first base 13 and the second base 14 are not limited in this embodiment of the application, that is, any shape and material are acceptable.

[0047] The provision of the first base and the second base makes it easier to control the movement of the limiting assembly 11 and the clamping assembly 12 .

[0048] like Figure 1 、 3 As shown in Figure 5, in some embodiments, the correcting device 1 further includes a mounting member 15, and the first limiting portion 111 and the clamping assembly 12 are arranged on the first base 13 through the mounting member 15, and the mounting member 15 can move along the first direction X relative to the first base 13.

[0049] The first position-limiting portion 111 and the clamping assembly 12 are disposed on the first base 13 via a mounting member 15. Specifically, one side of the mounting member 15 is connected to the first position-limiting portion 111 and the clamping assembly 12, and the other side is movably connected to the first base 13. The connection between the mounting member 15 and the first position-limiting portion 111 can be a detachable connection method such as bolts or a clamping connection, or a non-detachable connection method such as welding or bonding. Similarly, the connection between the mounting member 15 and the clamping assembly 12 can be a detachable connection method such as bolts or a clamping connection, or a non-detachable connection method such as welding or bonding.

[0050] The movable connection between the mounting member 15 and the first base 13 can be achieved using a guide rail and slider mechanism or a rack and pinion mechanism. For example, in some embodiments, one of the mounting member 15 and the first base 13 is provided with a guide rail extending along the first direction X, while the other is provided with a slider corresponding to the guide rail. The movement of the slider on the guide rail enables the mounting member 15 to move relative to the first base 13 along the first direction X.

[0051] By providing the mounting member 15, when the mounting member 15 moves relative to the first base 13 along the first direction X, the first limiting portion 111 and the clamping assembly 12 can move synchronously along the first direction X, thereby reducing the deviation caused by the relative movement between the first limiting portion 111 and the clamping assembly 12 and ensuring production accuracy.

[0052] like Figures 1 to 6 As mentioned, in some embodiments, the correction device 1 further includes a driving assembly 16 , which includes a first driving member 161 and a second driving member 162 , wherein the first driving member 161 is drivingly connected to the mounting member 15 ; and the second driving member 162 is drivingly connected to the clamping assembly 12 .

[0053] The first driving member 161 can be an electric cylinder, a pneumatic cylinder, a hydraulic rod or other components, or a cam structure. The second driving member 162 can also be an electric cylinder, a pneumatic cylinder, a hydraulic rod or other components, or a cam structure. It should be noted that the first driving member 161 and the second driving member 162 can be the same driving member, which can simultaneously drive the mounting member 15 and the clamping assembly 12; or they can be different driving members, which can drive the mounting member 15 and the clamping assembly 12 respectively. When the first driving member 161 and the second driving member 162 are different driving members, they can be the same type of driving members or different types of driving members.

[0054] By providing the first driving member 161, the mounting member 15 can be moved along the first direction X, thereby enabling the first limiting portion 111 and the clamping assembly 12 to approach or move away from the tab 21 along the first direction X, thereby limiting the movement of the tab 21 along the first direction X. By providing the second driving member 162, the clamping assembly 12 can be driven to complete the clamping and loosening of the tab 21 in the second direction Y, thereby achieving the correction of the tab 21 and the battery 2.

[0055] like Figures 1 to 6 As shown, in some embodiments, the first limiting portion 111 can move along the first direction X relative to the mounting member 15; and / or the second limiting portion 112 can move along the first direction X relative to the second base 14.

[0056] That is, in some embodiments, the first limiting portion 111 or the second limiting portion 112 can be moved along the first direction, thereby changing the size of the limiting portion 113 along the first direction X, thereby adapting to tabs 21 of different thicknesses and improving the compatibility of the correcting device 1. In other embodiments, both the first limiting portion 111 and the second limiting portion 112 can be moved along the first direction. In this case, not only the size of the limiting portion 113 along the first direction X can be changed, but also the position of the limiting portion 113 in the first direction X can be changed, further improving the compatibility of the correcting device 1.

[0057] The movable connection between the first limiting portion 111 and the mounting member 15 can be realized by a guide rail and slider mechanism or a gear rack mechanism. Similarly, the movable connection between the second limiting portion 112 and the second base 14 can be realized by a guide rail and slider mechanism or a gear rack mechanism.

[0058] By arranging the first limiting portion 111 and / or the second limiting member 112 to be movable along the first direction X, the size of the limiting portion 113 can be changed to adapt to tabs 21 of different thicknesses, thereby improving the compatibility of the correction device 1 .

[0059] In some embodiments, the correction device 1 further includes an elastic component, which is disposed between the first limiting portion 111 and the mounting member 15 .

[0060] The elastic component can be a component made of an elastic material such as rubber, or a spring. The elastic component can be detachably clamped between two opposing surfaces of the first limiting portion 111 and the mounting member 15. Specifically, a recessed portion can be provided on two opposing surfaces of the first limiting portion 111 and / or the mounting member 15, and the elastic component can be placed in the recessed portion. In this case, it should be noted that the length of the elastic component should be greater than the depth of the recessed portion to ensure that the elastic component can be compressed and provide a buffering effect. Of course, the elastic component can also be directly fixedly installed on two opposing surfaces of the first limiting portion 111 and / or the mounting member 15.

[0061] By providing the elastic component, when the first limiting portion 111 approaches the tab 21 along the first direction X, it can buffer the tab 21 and prevent the first limiting portion 111 and the second limiting portion 112 from damaging the tab 21 .

[0062] like Figures 1 to 6 As shown, in some embodiments, the correcting device 1 further includes a fixing assembly 18, which includes a first fixing portion 181 and a second fixing portion 182 spaced apart along the first direction X, and a receiving portion 183 for receiving the battery 2 is formed between the first fixing portion 181 and the second fixing portion 182; and the distance between the first fixing portion 181 and the second fixing portion 182 along the first direction X is variable to adjust the size of the receiving portion 183.

[0063] In some embodiments, the first fixing portion 182 and the second fixing portion 182 may be baffles extending along the second direction, and the battery 2 may be clamped and fixed in the accommodating portion 183 by the baffles, thereby fixing the battery 2.

[0064] In other embodiments, when the battery 2 is a cylindrical battery, the first fixing portion 181 and / or the second fixing portion 182 may be a component formed by a first cylinder and a second cylinder spaced apart along the second direction Y, wherein the first cylinder and the second cylinder may be complete cylinders or semi-cylinders. When the first cylinder and the second cylinder are complete cylinders, they may be fixed cylinders or cylinders that can rotate about their own axes, and this application does not impose any restrictions on this. When the first cylinder and the second cylinder are semi-cylinders, half of the cylinder should be arranged toward the other fixing portion to form the accommodating portion 183. It should be noted that the first cylinder and the second cylinder may be the same structure among the above-mentioned structures, or a combination of different structures among the above-mentioned structures. When one of the first fixing portion 181 and the second fixing portion 182 is a component formed by the first cylinder and the second cylinder, the other may also be the baffle structure described above.

[0065] The distance between the first fixing portion 181 and the second fixing portion 182 along the first direction X is variable. Specifically, one of the first fixing portion 181 and the second fixing portion 182 may be movable along the first direction X, or both the first fixing portion 181 and the second fixing portion 182 may be movable along the first direction X. In addition, the distance between the first fixing portion 181 and the second fixing portion 182 along the first direction X may be changed by a guide rail and slider mechanism, or by a connecting rod mechanism or a rack and pinion mechanism, and this is not limited in this embodiment of the present application.

[0066] By providing a fixing assembly 181, the battery 2 can be fixed in the correction device 1. In addition, by changing the distance between the first fixing portion 181 and the second fixing portion 182 along the first direction X, the battery 2 can be clamped and loosened. For example, when the battery 1 needs to be corrected, the distance between the first fixing portion 181 and the second fixing portion 182 along the first direction X becomes larger, thereby loosening the battery 2, allowing the battery 2 to rotate along the tab 2, and completing the correction of the battery 2 and the tab 21. After the correction is completed, the distance between the first fixing portion 181 and the second fixing portion 182 along the first direction X becomes smaller, which can achieve clamping of the battery 2, fix the battery 2, prevent the battery 2 from shifting after correction, and ensure the correction accuracy.

[0067] like Figure 2 、 4As shown in FIG6 , in some embodiments, the correction device 1 further includes a driving assembly 16 , and the driving assembly 16 further includes a third driving member 163 , and the third driving member 163 is drivingly connected to the first fixing portion 181 and / or the second fixing portion 182 .

[0068] Similarly, the third driving member 163 may also be an electric cylinder, a pneumatic cylinder, a hydraulic rod or other components, or may be a cam mechanism.

[0069] The third driving member 163 is drivingly connected to the first fixing portion 181 and / or the second fixing portion 182. That is, in some embodiments, the third driving member 163 is drivingly connected to one of the first fixing portion 181 and the second fixing portion 182, and the battery 2 is clamped and released by moving the first fixing portion 181 or the second fixing portion 182. In other embodiments, the third driving member 163 is drivingly connected to both the first fixing portion 181 and the second fixing portion 182, and the battery 2 is clamped and released by moving the first fixing portion 181 and the second fixing portion 182 closer to or farther away from each other, which results in faster clamping and release speeds.

[0070] like Figures 1 to 6 As shown, in some embodiments, the fixing assembly 18 further includes a mounting portion 184, the second fixing portion 182 is fixedly connected to the mounting portion 184, the first fixing portion 181 can move relative to the mounting portion 184 along the first direction X, and the third driving member 163 is drivingly connected to the first fixing portion 181.

[0071] The fixed connection between the second fixing portion 182 and the mounting portion 184 may be a detachable connection method such as threaded connection, snap connection, etc., or a non-detachable connection method such as welding, bonding, etc.

[0072] The movable connection between the first fixing portion 181 and the mounting portion 184 can be a guide rail slider connection method or a gear rack connection method.

[0073] The installation portion 184 can be provided to facilitate adjustment of the distance between the first fixing portion 181 and the second fixing portion 182 along the first direction X.

[0074] like Figures 1 to 6 As shown, in some embodiments, the fixing assembly 18 also includes a connecting assembly 185, the connecting assembly 185 includes a first connecting member 1851 and a second connecting member 1852, the first connecting member 1851 is connected to the first fixing portion 182, the second connecting member 1852 is connected to the mounting portion 184, and the first connecting member 1851 can move along the first direction X relative to the second connecting member 1852.

[0075] The connection between the first connecting member 1851 and the first fixing portion 182 can be a detachable connection method such as a threaded connection or a clamping connection, or a non-detachable connection method such as welding or bonding. Similarly, the connection between the second connecting member 1852 and the mounting portion 184 can be a detachable connection method such as a threaded connection or a clamping connection, or a non-detachable connection method such as welding or bonding.

[0076] The movable connection between the first connecting member 1851 and the second connecting member 1852 can be achieved by using a guide rail and slider connection method, or a gear rack connection method. For example, in some embodiments, one of the first connecting member 1851 and the second connecting member 1852 is configured as a guide rail extending along the first direction X, and the other is configured as a slider adapted to the guide rail, and the movable connection between the first connecting member 1851 and the second connecting member 1852 is achieved by the guide rail and slider mechanism.

[0077] By providing the first connecting member 1851 and the second connecting member 1852 , a movable connection between the first fixing portion 181 and the mounting portion 184 can be achieved, thereby achieving adjustment of the distance between the first fixing portion 181 and the second fixing portion 182 .

[0078] like Figures 1 to 6 As shown, in some embodiments, the connecting assembly 185 further includes an elastic member 1853 , which is disposed between the first connecting member 1851 and the second connecting member 1852 .

[0079] The elastic member 1853 can be a component made of an elastic material such as rubber, or a spring. The elastic member 1853 can be detachably clamped between two opposing surfaces of the first connecting member 1851 and the second connecting member 1852. Specifically, a recessed portion can be provided on two opposing surfaces of the first connecting member 1851 and / or the second connecting member 1852, and the elastic member 1853 can be placed in the recessed portion. In this case, it should be noted that the length of the elastic member 1853 should be greater than the depth of the recessed portion to ensure that the elastic member can be compressed and play a buffering role. Of course, the elastic member 1853 can also be directly fixedly provided on two opposing surfaces of the first connecting member 1851 and / or the second connecting member 1852.

[0080] The elastic member 1853 can play a buffering role when the first fixing portion 181 and the second fixing portion 182 clamp and fix the battery 2 , thereby preventing the battery 2 from being damaged by excessive clamping force.

[0081] In some embodiments, the first connecting member 1851 includes an axis extending along the second direction Y, and the second connecting member 1852 includes a hole portion, and the axis is arranged through the hole portion; the elastic member 1853 is sleeved on the axis portion, and one end of the elastic member 1853 abuts against the first connecting member 1851, and the other end abuts against the second connecting member 1852.

[0082] The cross-sectional shape of the shaft portion can be a regular shape such as a circle or a square, or an irregular shape. The hole portion has a shape corresponding to the shaft portion to ensure that the hole portion can be passed through the shaft portion and can move along the shaft portion.

[0083] The elastic member 1853 can be made of an elastic material such as rubber, or a spring. Sleeving the elastic member 1853 on the shaft not only secures the elastic member 1853 but also allows the elastic member 1853 to move along the direction of the shaft when compressed or stretched, thereby preventing the elastic member 1853 from falling out from between the first connecting member 1851 and the second connecting member 1852.

[0084] One end of the elastic member 1853 abuts the first connecting member 1851, and the other end abuts the second connecting member 1852, meaning that the elastic member 1853 is always in a compressed state. On the one hand, when the accommodating portion 183 needs to be enlarged, the first connecting member 1851 moves away from the second fixing portion 182 along the first direction X, and the elastic member 1853 is compressed. When the accommodating portion 183 needs to be reduced, the external force is simply removed, and the first connecting member 1851 returns to the clamped position under the elastic force of the elastic member 1853. This facilitates operation and reduces external driving force. On the other hand, the elastic member 1853's constant compression provides a clamping force, ensuring that the battery 2 can be clamped and fixed between the first fixing portion 181 and the second fixing portion 182 under the action of the elastic force.

[0085] like Figure 2 、 4 As shown in FIG6 , in some embodiments, the third driving member 163 is a pushing portion provided on the mounting member 15 , and the pushing portion is provided corresponding to the first fixing portion 181 to push the first fixing portion 181 to move along the first direction X.

[0086] The third driving member 163 is set as a pushing part on the mounting member 15. When the battery 1 needs to be corrected, the mounting member 15 moves along the first direction X toward the direction close to the battery 2, driving the first limiting portion 111, the clamping assembly 12 and the third driving member 163 to approach the battery 2 along the first direction X until the third driving member 163 abuts against the first fixing portion 181 and drives the first fixing portion 181 to move, so that the first fixing portion 181 moves away from the second fixing portion 182 along the first direction, that is, the distance between the first fixing portion 181 and the second fixing portion 182 along the first direction X becomes larger, thereby achieving the release of the battery 2. At the same time, the first limiting portion 111 and the second limiting portion 112 limit the tab 2, and the clamping assembly 12 clamps the tab 21 from the second direction Y so that the tab 21 can be corrected, and the battery 2 rotates and corrects along with the tab 21, completing the correction of the tab 21 and the battery 2. After the correction is completed, the mounting member 15 moves along the first direction X away from the battery 2, driving the first limiting portion 111, the clamping assembly 12 and the third driving member 163 to move along the first direction X away from the battery 2. At this time, the first fixing portion 181 moves along the first direction X toward the second fixing portion 182 under the elastic force of the elastic member 1853, so that the distance between the two becomes smaller. The fixing assembly 18 can clamp and fix the battery 2 under the action of the elastic force, thereby preventing the battery 2 from deflecting after correction and ensuring the correction accuracy.

[0087] Setting the third driving member 163 as the pushing part on the mounting member 15 can, on the one hand, realize the synchronous movement of the first limiting part 111, the clamping assembly 12 and the third driving member 163, thereby improving the correction accuracy; on the other hand, it can reduce the number of driving assemblies 16 and simplify the structure of the correction device 1.

[0088] like Figure 2 As shown, in some embodiments, the pushing portion is provided with an avoidance portion 1631 to avoid the battery 2 .

[0089] The shape of the avoidance portion 1631 is consistent with the outer surface of the battery 2. By providing the avoidance portion, the battery 2 can be avoided to prevent the battery 2 from being damaged during the correction process.

[0090] like Figures 1 to 6 As shown, in some embodiments, the correcting device 1 includes a plurality of clamping components 12 , a limiting component 11 and a fixing component 18 spaced apart along the second direction Y.

[0091] By providing a plurality of clamping assemblies 12 , limiting assemblies 11 and fixing assemblies 18 , a plurality of correction positions can be formed on the correction device 1 , thereby correcting the deviation of a plurality of batteries 2 at the same time, thereby improving production efficiency.

[0092] Specifically, such as Figures 1 to 6As shown, during correction, the mounting member 15 is driven by the first driving member 161 to move along the first direction X toward the direction close to the battery 2, thereby driving the first limiting portion 111, the clamping assembly 12 and the third driving member 163 to approach the battery 2 along the first direction X, until the pushing portion abuts against the first fixing portion 181 and drives the first fixing portion 181 to move, so that the distance between the first fixing portion 181 and the second fixing portion 182 along the first direction X becomes larger, thereby achieving the release of the battery 2. At the same time, the first limiting portion 111 and the second limiting portion 112 limit the tab 2, and the clamping assembly 12 is driven by the second driving member 162 to clamp the tab 21 from the second direction Y so that the tab 21 can be corrected, and the battery 2 rotates and corrects along with the tab 21, completing the correction of the tab 21 and the battery 2.

[0093] After the correction is completed, the mounting member 15 moves along the first direction X away from the battery 2 under the drive of the first driving member 161, thereby driving the first limiting portion 111, the clamping assembly 12 and the third driving member 163 to move away from the battery 2 along the first direction X. At this time, the first fixing portion 181 approaches the second fixing portion 182 along the first direction X under the elastic force of the elastic member 1853, so that the distance between the first fixing portion 181 and the second fixing portion 182 becomes smaller. The fixing assembly 18 can clamp and fix the battery 2 under the action of the elastic force, thereby preventing the battery 2 from deflecting after correction and ensuring the correction accuracy.

In order to make the description concise, not all possible combinations of the technical features in the above-mentioned embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

While the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the utility model patent. It should be noted that a person skilled in the art would be able to make various modifications and improvements without departing from the concept of the present invention, and these modifications and improvements fall within the scope of protection of the present invention.
