As used herein, the term "and / or" includes any and all combinations of one or more of the associated listed items.

[0058] In order to more clearly understand the embodiments of the present disclosure, the following describes the embodiments of the present disclosure in detail with reference to the accompanying drawings 1-13.

[0059] As shown in FIGS. 1-4, the present disclosure provides a clamp 1 for clamping a cylindrical battery 2, the clamp 1 comprising a first clamping portion 11 and a second clamping portion 12; wherein the first clamping portion 11 comprises a first cylinder 111 and a second cylinder 112 arranged at intervals along a first direction X; the second clamping portion 12 is arranged at intervals with the first clamping portion 11 along a second direction Y, the first clamping portion 11 and the second clamping portion 12 form a receiving portion 13 for accommodating the cylindrical battery 2 therebetween, the second direction Y is perpendicular to the first direction X; and the distance between the first clamping portion 11 and the second clamping portion 12 along the second direction Y is variable to adjust the size of the receiving portion 13.

[0060] The first clamping portion 11 comprises a first cylinder 111 and a second cylinder 112 arranged at intervals along a first direction X, wherein the first cylinder 111 and the second cylinder 112 can be a complete cylinder or a half cylinder. When the first cylinder 111 and the second cylinder 112 are complete cylinders, they can be fixed cylinders or cylinders rotatable about their own axes, and the present disclosure does not limit this. When the first cylinder 111 and the second cylinder 112 are half cylinders, the half of the cylinder should be arranged towards the second clamping portion 12 to form the receiving portion 13. It should be noted that the first cylinder 111 and the second cylinder 112 can be the same structure of the above-mentioned structures, or a combination of different structures of the above-mentioned structures.

[0061] The first direction X is a direction parallel to the axis line connecting the first cylinder 111 and the second cylinder 112. The second direction Y is perpendicular to the first direction X, that is, the second direction Y can be any direction in a plane perpendicular to the first direction X.

[0062] By arranging the first cylinder 111 and the second cylinder 112 at intervals along the first direction X, part of the accommodation portion 13 can be formed between the two cylinders. Firstly, when the cylindrical battery 2 is accommodated in the accommodation portion 13, the cylindrical battery 2 is in linear contact with the outer surfaces of the first cylinder 111 and the second cylinder 112 respectively, which can reduce the contact area and reduce the abrasion when the cylindrical battery 2 needs to be rotated. Secondly, when the diameter of the cylindrical battery 2 changes, the cylindrical battery 2 is only different in the position of the contact line with the outer surfaces of the two cylinders, and can still be accommodated between the first cylinder 111 and the second cylinder 112. Thirdly, when the cylindrical battery 2 is accommodated between the first cylinder 111 and the second cylinder 112, the cylindrical battery 2 can be arranged centrally between the two cylinders under the guidance of the outer surfaces of the two cylinders, so that the positioning accuracy of the cylindrical battery 2 is improved.

[0063] In some embodiments, the second clamping portion 12 can also be composed of two cylinders arranged at intervals along the first direction X to form an accommodation portion 13 for accommodating the cylindrical battery 2 between the four cylinders. Similarly, at this time, the two cylinders can be complete cylinders or half cylinders, and can be fixed complete cylinders or rotatable complete cylinders, which are not limited in the present disclosure. In other embodiments, the second clamping portion 12 can also be a baffle extending along the first direction X, and the cross section of the baffle can be circular, square or irregular.

[0064] The distance between the first clamping portion 11 and the second clamping portion 12 along the second direction Y can be changed. Specifically, one of the first clamping portion 11 and the second clamping portion 12 can move along the second direction Y, or both the first clamping portion 11 and the second clamping portion 12 can move along the second direction Y. In addition, the change of the distance between the first clamping portion 11 and the second clamping portion 12 along the second direction Y can be realized by a guide rail and slider mechanism, or by a connecting rod mechanism or a gear and rack mechanism, which are not limited in the embodiments of the present disclosure.

[0065] By changing the distance between the first clamping portion 11 and the second clamping portion 12 along the second direction Y, the cylindrical battery 2 can be clamped and released, and cylindrical batteries 2 of different diameters can be accommodated. For example, when the distance between the first clamping portion 11 and the second clamping portion 12 along the second direction Y is increased, the cylindrical battery 2 can be released, which facilitates the taking, placing and rotating of the cylindrical battery 2, and a cylindrical battery 2 of a larger diameter can be clamped. When the distance between the first clamping portion 11 and the second clamping portion 12 along the second direction Y is decreased, the cylindrical battery 2 can be clamped, which fixes the cylindrical battery 2, and a cylindrical battery 2 of a smaller diameter can be clamped.

[0066] In one aspect, the cylindrical battery 2 is clamped and accommodated in the accommodating portion 13 by setting the first clamping portion 11 and the second clamping portion 12, so that the clamping and fixing of the cylindrical battery 2 are realized, and the rotation or movement of the cylindrical battery 2 can be prevented, and the positioning accuracy is ensured. On the other hand, by adjusting the size of the accommodating portion 13, the clamping and loosening of the cylindrical battery 2 can be realized, and the fixing of the cylindrical battery 2 with different diameters can be realized, and the compatibility of the clamp 1 is improved.

[0067] As shown in FIG. 1, in some embodiments, the first cylinder 111 and / or the second cylinder 112 is a roller that can rotate along its own axis.

[0068] The first cylinder 111 and / or the second cylinder 112 is a roller that can rotate along its own axis, that is, in some embodiments, one of the first cylinder 111 and the second cylinder 112 is a roller that can rotate along its own axis; and in other embodiments, both the first cylinder 111 and the second cylinder 112 are rollers that can rotate along their own axes.

[0069] By setting the first cylinder 111 and / or the second cylinder 112 as a roller that can rotate along its own axis, when the cylindrical battery 2 rotates around its own axis, the friction between the cylindrical battery 2 and the first cylinder 111 and the second cylinder 112 can be reduced, and the wear and damage of the cylindrical battery 2 can be prevented.

[0070] As shown in FIGS. 1 to 4, in some embodiments, the second clamping portion 112 is a baffle extending in the first direction X.

[0071] It should be noted that the cross section of the baffle can be a regular shape such as a circle or a square, or can be an irregular shape, and the present disclosure does not limit this.

[0072] By setting the second clamping portion 112 as a baffle extending in the first direction X, the structure of the clamp 1 is simple and easy to produce and manufacture.

[0073] As shown in FIGS. 1 to 4, in some embodiments, the clamp 1 further comprises a mounting portion 14, the second clamping portion 12 is fixedly connected with the mounting portion 14, and the first clamping portion 11 is movable relative to the mounting portion 13 in the second direction Y to adjust the size of the accommodating portion 13.

[0074] The fixed connection between the second clamping portion 12 and the mounting portion 14 can adopt a detachable connection mode such as threaded connection or clamping, or can adopt a non-detachable connection mode such as welding or bonding.

[0075] The movable connection between the first clamping portion 11 and the mounting portion 13 can adopt a connection mode of a guide rail and a sliding block, or can adopt a connection mode of a gear and a rack.

[0076] By setting the mounting portion 13, it is easy to realize the adjustment of the distance between the first clamping portion 11 and the second clamping portion 12 along the second direction Y.

[0077] As shown in FIGS. 1, 2 and 4, in some embodiments, the clamp 1 further comprises a connecting assembly 15, the connecting assembly 15 comprising a first connecting piece 151 and a second connecting piece 152, the first connecting piece 151 being connected with the first clamping portion 11, the second connecting piece 152 being connected with the mounting portion 13, and the first connecting piece 151 and the second connecting piece 152 being movably connected.

[0078] The connection between the first connecting piece 151 and the first clamping portion 11 can adopt a detachable connection mode such as threaded connection, clamping, etc., or a non-detachable connection mode such as welding, bonding, etc. Similarly, the connection between the second connecting piece 152 and the mounting portion 13 can adopt a detachable connection mode such as threaded connection, clamping, etc., or a non-detachable connection mode such as welding, bonding, etc.

[0079] The movable connection between the first connecting piece 151 and the second connecting piece 152 can adopt a connection mode of guide rail and sliding block, or a connection mode of gear and rack. For example, in some embodiments, one of the first connecting piece 151 and the second connecting piece 152 is provided as a guide rail extending along the second direction Y, and the other is provided as a sliding block adapted to the guide rail, and the movable connection between the first connecting piece 151 and the second connecting piece 152 is realized through the guide rail and sliding block mechanism.

[0080] By setting the first connecting piece 151 and the second connecting piece 152, the movable connection of the first clamping portion 11 and the mounting portion 14 can be realized, and further the adjustment of the distance between the first clamping portion 11 and the second clamping portion 12 can be realized.

[0081] As shown in FIGS. 1 to 4, in some embodiments, the connecting assembly 15 further comprises an elastic piece 153, the elastic piece 153 being arranged between the first connecting piece 151 and the second connecting piece 152.

[0082] The elastic piece 153 can be a component made of elastic material such as rubber, or can be a spring. The elastic piece 153 can be detachably clamped between the two opposite surfaces of the first connecting piece 151 and the second connecting piece 152. Specifically, as shown in FIG. 5, recesses can be provided on the two opposite surfaces of the first connecting piece 151 and / or the second connecting piece 152, and the elastic piece 153 is arranged in the recesses. At this time, it should be noted that the length of the elastic piece 153 should be greater than the recess depth of the recesses, so as to ensure that the elastic piece can be compressed to play a buffering role. Of course, the elastic piece 153 can also be directly fixed on the two opposite surfaces of the first connecting piece 151 and / or the second connecting piece 152.

[0083] By setting the elastic member 153, when the first clamping part 11 and the second clamping part 12 clamp and fix the cylindrical battery 2, the elastic member 153 can play a buffering role, preventing the clamping force from being too large and damaging the cylindrical battery 2.

[0084] As shown in FIGS. 1-4, in some embodiments, the first connecting piece 151 includes a shaft part 1511 extending along the second direction Y, the second connecting piece 152 includes a hole part 1521, and the shaft part 1511 is disposed through the hole part 1521; the elastic member 153 is sleeved on the shaft part 1511, and one end of the elastic member 153 abuts against the first connecting piece 151 and the other end abuts against the second connecting piece 152.

[0085] The cross-sectional shape of the shaft part 1511 can be a regular shape such as a circle or a square, or an irregular shape. The hole part 1521 is in a shape corresponding to the shaft part 1511, so as to ensure that the hole part 1521 can be disposed on the shaft part 1511 and can move along the shaft part 1511.

[0086] The elastic member 153 can be a component made of an elastic material such as rubber, or can be a spring. By sleeving the elastic member 153 on the shaft part 1511, the elastic member 153 can be fixed, and can also move along the direction in which the elastic member 153 extends when compressed or stretched, preventing the elastic member 153 from coming out of the first connecting piece 151 and the second connecting piece 152.

[0087] One end of the elastic member 153 abuts against the first connecting piece 151 and the other end abuts against the second connecting piece 152, that is, the elastic member 153 is always in a compressed state. On the one hand, when it is necessary to increase the accommodating part 13, the first connecting piece 151 moves away from the second clamping part 12 along the second direction Y, at which time the elastic member 153 is compressed; when it is necessary to reduce the accommodating part 13, the first connecting piece 151 can return to the clamping position under the action of the elastic force of the elastic member 153 by removing the external force, which is convenient to operate and can reduce the external driving force. On the other hand, the elastic member 153 is always in a compressed state, which can provide a clamping force to ensure that the cylindrical battery 2 can be clamped and fixed between the first clamping part 11 and the second clamping part 12 under the action of the elastic force.

[0088] As shown in FIGS. 1 and 2, in some embodiments, the end of the first connecting piece 151 close to the cylindrical battery 2 is an abutting part 1512, and the abutting part 1512 is made of a magnetic material, and / or a magnetic member 16 is disposed between the first cylindrical body 111 and the second cylindrical body 112.

[0089] That is, in some embodiments, as shown in FIGS. 1-3, the abutting portion 1512 is made of a magnetic material to magnetically attract and fix the upper portion of the cylindrical battery 2. In other embodiments, as shown in FIGS. 1 and 3, a magnetic member 16 is arranged between the first cylinder 111 and the second cylinder 112 to magnetically attract and fix the middle portion of the cylindrical battery 2. In still other embodiments, as shown in FIGS. 1 and 3, the abutting portion 1512 is made of a magnetic material and a magnetic member 16 is arranged between the first cylinder 111 and the second cylinder 112 to magnetically attract and fix the upper portion and the middle portion of the cylindrical battery 2.

[0090] The abutting portion 1512 is made of a magnetic material, that is, the abutting portion 1512 can be a permanent magnet or an electromagnet. Similarly, the magnetic member 16 can also be a permanent magnet or an electromagnet. Preferably, the abutting portion 1512 is made of an electromagnet and the magnetic member 16 is an electromagnet. When it is necessary to fix the cylindrical battery 2, the abutting portion 1512 and the magnetic member 16 are powered to have magnetism to attract and fix the cylindrical battery 2. When it is necessary to rotate or loosen the cylindrical battery 2, the abutting portion 1512 and the magnetic member 16 are powered off to lose magnetism, which facilitates switching between different states of the cylindrical battery 2.

[0091] In some embodiments, when the cylindrical battery 2 is made of a magnetic material such as iron, the abutting portion 1512 made of a magnetic material can magnetically attract and fix the cylindrical battery 2 on the abutting portion 1512, which ensures the fixing accuracy of the cylindrical battery 2. In other embodiments, when the first connecting member 151 is also made of a magnetic material, the abutting portion 1512 can be fixed on the first connecting member 151 by magnetic attraction, which facilitates replacement of the abutting portion 1512 to adapt to cylindrical batteries 2 of different diameters.

[0092] As shown in FIGS. 1-3, in some embodiments, the surface of the abutting portion 1512 close to the cylindrical battery 2 is a circular arc surface corresponding to the outer surface of the cylindrical battery 2. The circular arc surface can prevent the cylindrical battery 2 from interfering with the first connecting member 151.

[0093] As shown in FIGS. 1-3, in some embodiments, the clamp 1 includes a plurality of first clamping portions 11 arranged at intervals along the first direction X, and a plurality of accommodating portions 13 are formed between the plurality of first clamping portions 11 and the second clamping portion 12.

[0094] The plurality of first clamping portions 11 can form a plurality of accommodating portions 13 on the clamp 1, which can simultaneously clamp and fix a plurality of cylindrical batteries 2, thereby improving production efficiency.

[0095] As shown in FIGS. 6-8, another aspect of the present disclosure provides a conveying line, which includes the above-described clamp 1 and a driving device 3. The driving device 3 is drivingly connected with the first clamping portion 11 and / or the second clamping portion 12 to adjust the size of the accommodating portion 13.

[0096] The driving device 3 can be an electric cylinder, a pneumatic cylinder, a hydraulic cylinder, etc., and the present disclosure does not limit the same. The driving device 3 is drivingly connected with the first clamping part 11 and / or the second clamping part 12, that is, in some embodiments, the driving device 3 is drivingly connected with one of the first clamping part 11 and the second clamping part 12, so as to adjust the accommodation part 13; and in other embodiments, the driving device 3 is drivingly connected with both the first clamping part 11 and the second clamping part 12, and drives both to move away from each other, so as to adjust the accommodation part 13, with a fast adjustment speed.

[0097] By arranging the above clamping jig 1 and the driving device 3, when the cylindrical battery 2 is conveyed on the conveying line, the cylindrical battery 2 can be clamped and fixed to prevent rotation or movement of the cylindrical battery 2, and the positioning accuracy is ensured; and the size of the accommodation part 13 can be adjusted by the driving device 3, so as to clamp and release the cylindrical battery 2.

[0098] As shown in FIGS. 6-8, in some embodiments, the driving device 3 includes a protruding part 31 and a guide assembly 32. The protruding part 31 is arranged on the first clamping part 11 and / or the second clamping part 12. The guide assembly 32 includes a guide part 321 extending along the first direction X. The guide part 321 abuts against the protruding part 31, and the height of the guide part 321 protruding towards the protruding part 31 along the first direction X gradually increases first and then gradually decreases.

[0099] The protruding part 31 is arranged on the first clamping part 11 and / or the second clamping part 12, that is, in some embodiments, the protruding part 31 is arranged on the first clamping part 11 or the second clamping part 12, and the movement of the first clamping part 11 or the second clamping part 12 is driven to adjust the accommodation part 13; and in other embodiments, the first clamping part 11 and the second clamping part 12 are both provided with the protruding part 31, and the movement of the first clamping part 11 and the second clamping part 12 is driven to adjust the accommodation part 13, with a faster adjustment speed.

[0100] As shown in FIG. 8, the height of the guide part 321 protruding towards the protruding part 31 along the first direction X gradually increases first and then gradually decreases, that is, the width of the guide part 321 in the second direction Y along the first direction X gradually increases first and then gradually decreases, that is, the guide part 321 has a structure of wide in the middle and narrow on both sides. Specifically, when the protruding part 31 passes through the guide part 321 along the first direction X, the protruding part 31 moves along the second direction Y under the guidance of the guide part 321, so that the first clamping part 11 and / or the second clamping part 12 move in the second direction Y.

[0101] By setting the guide portion 321 to gradually increase in height first and then gradually decrease in height in the direction of the convex portion 31 in the first direction X, when the convex portion 31 passes through the guide portion 321 in the first direction X, the receiving portion 13 first increases to loosen the cylindrical battery 2 and then decreases to clamp the cylindrical battery 2, thereby achieving the taking and placing of the cylindrical battery 2.

[0102] As shown in FIG. 7, in some embodiments, the convex portion 31 is a roller that can rotate around its own axis.

[0103] By setting the convex portion 31 as a roller that can rotate around its own axis, when the convex portion 31 moves along the guide portion 321, it is in a rolling movement, which reduces the friction between the convex portion 31 and the guide portion 321 and improves the service life of the driving device 3.

[0104] As shown in FIGS. 9 to 13, in another aspect of the present disclosure, a correction system is provided for the correction of the tab 21 of the cylindrical battery 2, which includes the clamp 1, a correction assembly 4, and a driving assembly 5. The correction assembly 4 includes a correction wheel 41 that can rotate around its own axis, and the correction wheel 41 is arranged corresponding to the first clamping portion 11. The driving assembly 5 includes a first driving portion 51 and a second driving portion 52. The first driving portion 51 is drivingly connected with the correction assembly 4 to drive the correction wheel 41 to move closer to or farther away from the cylindrical battery 2. The second driving portion 52 is drivingly connected with the correction wheel 41.

[0105] The second driving portion 52 is drivingly connected with the correction wheel 41, and the second driving portion 52 can be a motor that drives the correction wheel 41 to rotate around its own axis.

[0106] The first driving portion 51 is drivingly connected with the correction assembly 4, and the first driving portion 51 can be a cam mechanism, or an electric cylinder, a pneumatic cylinder, a hydraulic rod, etc. When correcting, the first driving portion 51 drives the correction wheel 41 to move closer to the cylindrical battery 2, so that the cylindrical battery 2 is clamped between the correction wheel 41 and the first clamping portion 11, thereby enabling the correction wheel 41 to drive the cylindrical battery 2 to rotate, completing the correction of the tab 21.

[0107] By setting the correction wheel 41, when the correction wheel 41 rotates around its own axis, it can drive the cylindrical battery 2 to rotate, and in turn drive the tab 21 of the cylindrical battery 2 to rotate, thereby achieving the adjustment of the angle of the tab 21 and correcting the angle of the tab 21.

[0108] As shown in FIGS. 9 to 12, in some embodiments, the correction system further includes a pushing assembly 7, which includes a pushing portion 71. The driving assembly 5 includes a third driving portion 53 that is drivingly connected with the pushing portion 71 to drive the pushing portion 71 to move closer to or farther away from the tab 21.

[0109] The third driving part 53 can be a cam mechanism, or an electric cylinder, a pneumatic cylinder, a hydraulic rod, etc. It should be noted that the first driving part 51, the second driving part 52 and the third driving part 53 can be the same driving component, and simultaneously drive the deviation correction wheel 41, the deviation correction assembly 4 and the pushing part 71; or can be different driving components, and respectively drive the deviation correction wheel 41, the deviation correction assembly 4 and the pushing part 71. When the first driving part 51, the second driving part 52 and the third driving part 53 are different driving components, they can be the same type of driving component or different types of driving components.

[0110] In some embodiments, the tab 21 can be inclined to the axial direction of the cylindrical battery 2, which affects the accuracy of the tab 21 deviation correction. The pushing part 71 can be used to correct the inclined tab 21, thereby improving the quality of the deviation correction.

[0111] As shown in FIGS. 9 and 10, in some embodiments, the end of the pushing part 71 close to the tab 21 is a circular arc.

[0112] The end of the pushing part 71 close to the tab 21 is set to be a circular arc, which can reduce the pressure between the end 72 and the tab 21 when pushing the tab 21, thereby preventing damage to the tab 21.

[0113] As shown in FIGS. 9 to 12, in some embodiments, the deviation correction system further comprises a detection device 6 corresponding to the tab 21, which is used to detect the tab 21, and the detection device 6 is located upstream of the pushing assembly 7 in the conveying direction.

[0114] In some embodiments, the detection device 6 is an optical fiber detection mechanism, which can detect the position of the tab 21 to improve the deviation correction effect of the deviation correction system. In other embodiments, the detection device 6 can also be an image detection mechanism, which can determine the position and angle of the tab 21 by taking a photo of the tab 21.

[0115] The detection device 6 is located upstream of the pushing assembly 7 in the conveying direction, that is, the cylindrical battery 2 first passes through the detection of the detection device 6 and then passes through the pushing mechanism 7 to push the tab 21 during the conveying process.

[0116] The detection device 6 can detect the position of the tab, ensure that the cylindrical battery 2 rotates to the position corresponding to the tab 21 and the pushing part 71, and at this time the pushing part 71 can push the tab 21 away from the axis of the cylindrical battery 2 from the radial direction of the cylindrical battery 2, thereby improving the deviation correction effect.

[0117] As shown in FIG. 9, in some embodiments, the deviation correction assembly 4 comprises a base 42, and the deviation correction wheel 41 is movably arranged on the base 42, and the first driving part 51 drives the deviation correction wheel 41 to move relative to the base 42.

[0118] By setting the base 42, the base 42 is fixed, and the deviation correction wheel 41 is driven to move by the first driving part 51, so that the deviation correction wheel 41 is close to or away from the cylindrical battery 2.

[0119] As shown in Fig. 13, in some embodiments, the deviation correction system comprises the conveying line and two deviation correction assemblies 4, and the pushing assembly 7 is arranged between the two deviation correction assemblies 4.

[0120] By arranging the pushing assembly 7 between the two deviation correction assemblies 4, the inclined tab 21 can be pushed to the correct position by the pushing assembly 7 after the cylindrical battery 2 is deviated once, and then the second deviation correction is performed by the deviation correction assembly 4, so that the deviation correction accuracy can be improved.

[0121] Specifically, as shown in Figs. 1 to 13, when feeding, the convex part 31 passes through the guide part 321 along the first direction X, thereby driving the first clamping part 11 to move away from the second clamping part 12, the accommodating part 13 is enlarged to put in the cylindrical battery 2, the convex part 31 continues to pass through the guide part 321 along the first direction X, and the first clamping part 11 is driven to move close to the second clamping part 12 by the elastic force of the elastic part 13, so as to clamp the cylindrical battery 2, thereby completing the feeding of the cylindrical battery 2.

[0122] When deviation correction, the second driving part 52 drives the deviation correction wheel 41 to rotate, and at the same time, the first driving part 51 drives the deviation correction wheel 41 to move close to the cylindrical battery 2, so that the cylindrical battery 2 is clamped between the deviation correction wheel 41 and the first clamping part 11, thereby driving the deviation correction wheel 41 to rotate the cylindrical battery 2. Then, the detection device 6 detects the position of the tab, so that the cylindrical battery 2 stops rotating after rotating to the position where the tab 21 corresponds to the pushing part 71, thereby completing the first deviation correction of the tab 21, and at this time, the pushing part 71 can push the tab 21 away from the axis of the cylindrical battery 2 in the radial direction of the cylindrical battery 2, so as to avoid the tab 21 from tilting towards the axis of the cylindrical battery 2. Finally, the deviation correction wheel 41 drives the cylindrical battery 2 to rotate again, thereby making the tab 41 restore to the correct angle under the action of centrifugal force, thereby completing the second deviation correction of the tab 21.

[0123] When discharging, the convex part 31 passes through the guide part 321 along the first direction X, thereby driving the first clamping part 11 to move away from the second clamping part 12, and the accommodating part 13 is first enlarged to release the cylindrical battery 2, thereby completing the discharging of the cylindrical battery 2.
