[0065] In order to understand the embodiments of the present application more clearly, the following Figures 1 to 13 The embodiments of the present application are described in detail.

[0066] like Figures 1 to 4 As shown, on the one hand, the present application provides a clamp 1 for clamping a cylindrical battery 2, and the clamp 1 includes a first clamping portion 11 and a second clamping portion 12; wherein, the first clamping portion 11 includes a first cylinder 111 and a second cylinder 112 spaced apart along a first direction X; the second clamping portion 12 is spaced apart from the first clamping portion 11 along a second direction Y, and a receiving portion 13 for receiving the cylindrical battery 2 is formed between the first clamping portion 11 and the second clamping portion 12, and 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.

[0067] The first clamping portion 11 includes a first cylinder 111 and a second cylinder 112 spaced apart along a first direction X, wherein the first cylinder 111 and the second cylinder 112 can be complete cylinders or semi-cylinders. When the first cylinder 111 and the second cylinder 112 are complete cylinders, both can be fixed cylinders or cylinders that can rotate around their own axes, and this application does not impose any restrictions on this. When the first cylinder 111 and the second cylinder 112 are semi-cylinders, half of the cylinder should be arranged toward the second clamping portion 12 to form a receiving portion 13. It should be noted that the first cylinder 111 and the second cylinder 112 can be the same structure among the above-mentioned structures, or a combination of different structures among the above-mentioned structures.

[0068] The first direction X is parallel to the axis 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.

[0069] By arranging the first cylinder 111 and the second cylinder 112 at intervals along the first direction X, a portion of the accommodating portion 13 can be formed between the two cylinders. First, when the cylindrical battery 2 is accommodated in the accommodating portion 13, it makes line contact with the outer surfaces of the first cylinder 111 and the second cylinder 112, respectively. This reduces the contact area and reduces wear when the cylindrical battery 2 needs to rotate. Second, when the diameter of the cylindrical battery 2 changes, the cylindrical battery 2 can still be accommodated between the first cylinder 111 and the second cylinder 112, with only the position of the contact line with the outer surfaces of the two cylinders changing. Third, when the cylindrical battery 2 is accommodated between the first cylinder 111 and the second cylinder 112, it can be centered between the two cylinders under the guidance of the outer surfaces of the two cylinders, thereby improving the positioning accuracy of the cylindrical battery 2.

[0070] In some embodiments, the second clamping portion 12 may also be composed of two cylinders spaced apart along the first direction X, so as to form a receiving portion 13 for accommodating the cylindrical battery 2 between the four cylinders. Similarly, the two cylinders may be complete cylinders or semi-cylinders, and may be fixed complete cylinders or rotatable complete cylinders, and this application does not impose any restrictions on this. In other embodiments, the second clamping portion 12 may also be a baffle extending along the first direction X, and the cross-section of the baffle may be circular, square, or irregular.

[0071] The distance between the first clamping portion 11 and the second clamping portion 12 along the second direction Y is variable. Specifically, one of the first clamping portion 11 and the second clamping portion 12 may be movable along the second direction Y, or both the first clamping portion 11 and the second clamping portion 12 may be movable along the second direction Y. In addition, the distance between the first clamping portion 11 and the second clamping portion 12 along the second direction Y may be changed by a guide rail slider mechanism, or by a connecting rod mechanism or a rack and pinion mechanism, and this is not limited in the embodiments of the present application.

[0072] 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 loosened, and can accommodate cylindrical batteries 2 of different diameters. For example, when the distance between the first clamping portion 11 and the second clamping portion 12 along the second direction Y increases, the cylindrical battery 2 can be loosened, thereby facilitating the placement and rotation of the cylindrical battery 2, while also allowing the clamping of cylindrical batteries 2 with larger diameters. Conversely, when the distance between the first clamping portion 11 and the second clamping portion 12 along the second direction Y decreases, the cylindrical battery 2 can be clamped, thereby securing the cylindrical battery 2, while also allowing the clamping of cylindrical batteries 2 with smaller diameters.

[0073] On the one hand, by providing the first clamping portion 11 and the second clamping portion 12, the cylindrical battery 2 is clamped and accommodated within the accommodating portion 13, thereby clamping and securing the cylindrical battery 2, preventing the cylindrical battery 2 from rotating or moving, and ensuring positioning accuracy. On the other hand, by adjusting the size of the accommodating portion 13, the cylindrical battery 2 can be clamped and released, and cylindrical batteries 2 of different diameters can be secured, thereby improving the compatibility of the clamp 1.

[0074] like Figure 1 As shown, in some embodiments, the first cylinder 111 and / or the second cylinder 112 is a roller that can rotate along its own axis.

[0075] 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; while in other embodiments, the first cylinder 111 and the second cylinder 112 are both rollers that can rotate along their own axis.

[0076] By configuring the first cylinder 111 and / or the second cylinder 112 as rollers that can rotate along their own axes, when the cylindrical battery 2 rotates around its own axis, the friction between it and the first cylinder 111 and the second cylinder 112 can be reduced, thereby preventing wear and damage to the cylindrical battery 2.

[0077] like Figures 1 to 4 As shown, in some embodiments, the second clamping portion 112 is a baffle extending along the first direction X.

[0078] It should be noted that the cross-section of the baffle can be a regular shape such as a circle or a square, or an irregular shape, and this application does not impose any restrictions on this.

[0079] By configuring the second clamping portion 112 as a baffle extending along the first direction X, the structure of the clamp 1 is simplified and easy to manufacture.

[0080] like Figures 1 to 4As shown, in some embodiments, the clamp 1 further includes a mounting portion 14 , the second clamping portion 12 is fixedly connected to the mounting portion 14 , and the first clamping portion 11 can move relative to the mounting portion 13 along the second direction Y to adjust the size of the accommodating portion 13 .

[0081] The fixed connection between the second clamping portion 12 and the mounting portion 14 may be a detachable connection method such as threaded connection, clip connection, etc., or a non-detachable connection method such as welding, bonding, etc.

[0082] The movable connection between the first clamping portion 11 and the mounting portion 13 can be a guide rail and slider connection method, or a gear rack connection method.

[0083] By providing the mounting portion 13 , it is easy to adjust the distance between the first clamping portion 11 and the second clamping portion 12 along the second direction Y.

[0084] like Figure 1 、 2 As shown in Figures 4 and 5, in some embodiments, the clamp 1 further includes a connecting assembly 15, the connecting assembly 15 includes a first connecting member 151 and a second connecting member 152, the first connecting member 151 is connected to the first clamping portion 11, the second connecting member 152 is connected to the mounting portion 13, and the first connecting member 151 and the second connecting member 152 are movably connected.

[0085] The connection between the first connecting member 151 and the first clamping portion 11 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 152 and the mounting portion 13 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.

[0086] The movable connection between the first connecting member 151 and the second connecting member 152 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 151 and the second connecting member 152 is configured as a guide rail extending along the second direction Y, and the other is configured as a slider adapted to the guide rail, and the movable connection between the first connecting member 151 and the second connecting member 152 is achieved by using a guide rail and slider mechanism.

[0087] By providing the first connecting member 151 and the second connecting member 152 , the first clamping portion 11 and the mounting portion 14 can be movably connected, thereby achieving adjustment of the distance between the first clamping portion 11 and the second clamping portion 12 .

[0088] like Figures 1 to 4As shown, in some embodiments, the connecting assembly 15 further includes an elastic member 153 , which is disposed between the first connecting member 151 and the second connecting member 152 .

[0089] The elastic member 153 can be a member made of elastic material such as rubber, or a spring. The elastic member 153 can be detachably clamped between the two opposite surfaces of the first connecting member 151 and the second connecting member 152. Specifically, Figure 5 As shown, recessed portions can be provided on two opposing surfaces of the first connecting member 151 and / or the second connecting member 152, and the elastic member 153 can be placed in the recessed portions. It should be noted that the length of the elastic member 153 should be greater than the depth of the recessed portions to ensure that the elastic member can be compressed and provide a buffering effect. Alternatively, the elastic member 153 can be directly fixedly provided on two opposing surfaces of the first connecting member 151 and / or the second connecting member 152.

[0090] By providing the elastic member 153 , when the first clamping portion 11 and the second clamping portion 12 clamp and fix the cylindrical battery 2 , a buffering effect can be played, thereby preventing the cylindrical battery 2 from being damaged by excessive clamping force.

[0091] like Figures 1 to 4 As shown, in some embodiments, the first connecting member 151 includes an axis portion 1511 extending along the second direction Y, and the second connecting member 152 includes a hole portion 1521, and the axis portion 1511 is arranged through the hole portion 1521; the elastic member 153 is sleeved on the axis portion 1511, and one end of the elastic member 153 abuts against the first connecting member 151, and the other end abuts against the second connecting member 152.

[0092] The cross-sectional shape of the shaft portion 1511 can be a regular shape such as a circle or a square, or an irregular shape. The hole portion 1521 is a shape corresponding to the shaft portion 1511 to ensure that the hole portion 1521 can be penetrated on the shaft portion 1511 and can move along the shaft portion 1511.

[0093] The elastic member 153 can be made of an elastic material such as rubber, or a spring. Sleeving the elastic member 153 on the shaft 1511 not only secures the elastic member 153 but also allows the elastic member 153 to move along the direction of the shaft 1511 when compressed or stretched, thereby preventing the elastic member 153 from falling out from between the first connecting member 151 and the second connecting member 152.

[0094] One end of the elastic member 153 abuts the first connecting member 151, and the other end abuts the second connecting member 152, that is, the elastic member 153 is always in a compressed state. On the one hand, when the accommodating portion 13 needs to be enlarged, the first connecting member 151 is moved away from the second clamping portion 12 along the second direction Y, and the elastic member 153 is compressed at this time; when the accommodating portion 13 needs to be reduced, the external force only needs to be removed, and the first connecting member 151 can be restored to the clamping position under the action of the elastic force of the elastic member 153, which is convenient to operate and can reduce external driving force. On the other hand, the elastic member 153 is always in a compressed state to provide clamping force, ensuring that the cylindrical battery 2 can be clamped and fixed between the first clamping portion 11 and the second clamping portion 12 under the action of the elastic force.

[0095] like Figure 1 and Figure 2 As shown, in some embodiments, the end of the first connecting member 151 close to the cylindrical battery 2 is an abutment portion 1512, and the abutment portion 1512 is made of a magnetic material, and / or a magnetic member 16 is provided between the first cylinder 111 and the second cylinder 112.

[0096] That is, in some embodiments, as Figures 1 to 3 As shown, the abutment portion 1512 is made of magnetic material to magnetically fix the upper portion of the cylindrical battery 2. In other embodiments, such as Figure 1 and Figure 3 As shown, a magnetic member 16 is provided between the first cylinder 111 and the second cylinder 112 to magnetically fix the middle portion of the cylindrical battery 2. In some further embodiments, as Figure 1 and Figure 3 As shown, the abutting portion 1512 is made of magnetic material and a magnetic member 16 is provided between the first cylinder 111 and the second cylinder 112 to magnetically fix the upper and middle parts of the cylindrical battery 2 .

[0097] The abutment portion 1512 is made of a magnetic material, that is, the abutment 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 abutment portion 1512 is made of an electromagnet and the magnetic member 16 is an electromagnet. When fixing is required, the abutment portion 1512 and the magnetic member 16 are energized to make them magnetic and thereby adsorb and fix the cylindrical battery 2. When the cylindrical battery 2 needs to be rotated or released, the abutment portion 1512 and the magnetic member 16 only need to be de-energized to lose the magnetic force, thereby facilitating the switching of the cylindrical battery 2 between different states.

[0098] In some embodiments, when the cylindrical battery 2 is made of a magnetic material such as iron, the abutting portion 1512 can be magnetically fixed to the abutting portion 1512 by setting it to a magnetic material, thereby ensuring 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 to the first connecting member 151 by magnetic attraction, which facilitates the replacement of the abutting portion 1512 to accommodate cylindrical batteries 2 of different diameters.

[0099] like Figures 1 to 3 As shown, in some embodiments, the surface of the abutting portion 1512 close to the cylindrical battery 2 is an arc-shaped surface corresponding to the outer surface of the cylindrical battery 2. By setting the arc-shaped surface, interference between the cylindrical battery 2 and the first connecting member 151 can be prevented.

[0100] like Figures 1 to 3 As shown, in some embodiments, the clamp 1 includes a plurality of first clamping portions 11 spaced apart 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 portions 12 .

[0101] By providing a plurality of first clamping portions 11 , a plurality of receiving portions 13 can be formed on the fixture 1 , thereby simultaneously clamping and fixing a plurality of cylindrical batteries 2 , thereby improving production efficiency.

[0102] like Figures 6 to 8 As shown, the present application provides a conveyor line on the other hand, comprising: the above-mentioned clamp 1 and a driving device 3, the driving device 3 is driven and connected to the first clamping part 11 and / or the second clamping part 12 to adjust the size of the accommodating part 13.

[0103] The driving device 3 can be a motor, or an electric cylinder, a pneumatic cylinder, a hydraulic rod, etc., and the embodiments of the present application do not limit this. The driving device 3 is driven and connected to the first clamping portion 11 and / or the second clamping portion 12. That is, in some embodiments, the driving device 3 is driven and connected to one of the first clamping portion 11 and the second clamping portion 12, thereby adjusting the accommodating portion 13; while in other embodiments, the driving device 3 is driven and connected to both the first clamping portion 11 and the second clamping portion 12, driving the two to move relative to or away from each other, thereby adjusting the accommodating portion 13, and the adjustment speed is fast.

[0104] By providing the above-mentioned clamp 1 and driving device 3, when conveying cylindrical batteries 2 on the conveyor line, the cylindrical batteries 2 can be clamped and fixed to prevent the cylindrical batteries 2 from rotating or moving, thereby ensuring positioning accuracy; and the size of the accommodating portion 13 can be adjusted by the driving device 3 to achieve clamping and loosening of the cylindrical batteries 2.

[0105] like Figures 6 to 8As shown, in some embodiments, the driving device 3 includes a protrusion 31 and a guide assembly 32, the protrusion 31 is arranged on the first clamping portion 11 and / or the second clamping portion 12; the guide assembly 32 includes a guide portion 321 extending along the first direction X, the guide portion 321 abuts against the protrusion 31, and the height of the guide portion 321 protruding toward the protrusion 31 along the first direction X first gradually increases and then gradually decreases.

[0106] The protrusion 31 is provided on the first clamping portion 11 and / or the second clamping portion 12, that is, in some embodiments, the protrusion 31 is provided on the first clamping portion 11 or the second clamping portion 12, and the adjustment of the accommodating portion 13 is achieved by driving the movement of the first clamping portion 11 or the second clamping portion 12; in other embodiments, the protrusion 31 is provided on both the first clamping portion 11 and the second clamping portion 12, and the adjustment of the accommodating portion 13 is achieved by driving the movement of the first clamping portion 11 and the second clamping portion 12, and the adjustment speed is faster.

[0107] like Figure 8 As shown, the height of the guide portion 321 protruding toward the protrusion 31 along the first direction X first gradually increases and then gradually decreases. That is, the width of the guide portion 321 along the second direction Y first gradually increases and then gradually decreases along the first direction X. In other words, the guide portion 321 has a structure that is wide in the middle and narrow at both sides along the first direction X. Specifically, when the protrusion 31 passes through the guide portion 321 along the first direction X, the protrusion 31 moves along the second direction Y under the guidance of the guide portion 321, causing the first clamping portion 11 and / or the second clamping portion 12 to move in the second direction Y.

[0108] By setting the guide portion 321 to a structure in which the height of the protrusion 31 along the first direction X gradually increases and then gradually decreases, when the protrusion 31 passes through the guide portion 321 along the first direction X, the accommodating portion 13 first increases to loosen the cylindrical battery 2 and then decreases to clamp the cylindrical battery 2, thereby realizing the taking and placing of the cylindrical battery 2.

[0109] like Figure 7 As shown, in some embodiments, the protrusion 31 is a roller that can rotate around its own axis.

[0110] The protrusion 31 is configured as a roller that can rotate around its own axis. When the protrusion 31 moves along the guide portion 321 , it moves in a rolling manner, which reduces the friction between the protrusion 31 and the guide portion 321 and increases the service life of the driving device 3 .

[0111] like Figures 9 to 13As shown, on the other hand, the present application provides a correction system for correcting the tab 21 of a cylindrical battery 2. The correction system includes: a clamp 1, a correction component 4 and a drive component 5. The correction component 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 part 11; the drive component 5 includes a first drive part 51 and a second drive part 52. The first drive part 51 is driven and connected to the correction component 4 to drive the correction wheel 41 to approach or move away from the cylindrical battery 2; the second drive part 52 is driven and connected to the correction wheel 41.

[0112] The second driving part 52 is drivingly connected to the deflection correcting wheel 41 . The second driving part 52 may be a motor, which drives the deflection correcting wheel 41 to rotate around its own axis.

[0113] The first driving unit 51 is drivably connected to the deflection correction assembly 4. The first driving unit 51 can be a cam mechanism, an electric cylinder, a pneumatic cylinder, a hydraulic rod, or other components. During deflection correction, the first driving unit 51 drives the deflection correction wheel 41 toward the cylindrical battery 2, clamping the cylindrical battery 2 between the deflection correction wheel 41 and the first clamping unit 11. The deflection correction wheel 41 then drives the cylindrical battery 2 to rotate, correcting the deflection of the tab 21.

[0114] By providing the correcting wheel 41 , the correcting wheel 41 can drive the cylindrical battery 2 to rotate when rotating around its own axis, and further drive the tab 21 of the cylindrical battery 2 to rotate, thereby adjusting the angle of the tab 21 and correcting the angle of the tab 21 .

[0115] like Figures 9 to 12 As shown, in some embodiments, the correction system further includes a pushing component 7, the pushing component 7 includes a pushing portion 71, and the driving component 5 includes a third driving portion 53 drivingly connected to the pushing portion 71 to drive the pushing portion 71 to approach or move away from the pole ear 21.

[0116] The third drive unit 53 can be a cam mechanism, or it can be an electric cylinder, a pneumatic cylinder, a hydraulic rod, or other component. It should be noted that the first drive unit 51, the second drive unit 52, and the third drive unit 53 can be the same drive component, simultaneously driving the correcting wheel 41, the correcting assembly 4, and the pusher 71; or they can be different drive components, driving the correcting wheel 41, the correcting assembly 4, and the pusher 71 respectively. When the first drive unit 51, the second drive unit 52, and the third drive unit 53 are different drive components, they can be the same type or different types.

[0117] In some embodiments, the tab 21 may be tilted toward the axis of the cylindrical battery 2 , which affects the accuracy of the tab 21 correction. By providing the pushing portion 71 , the tilted tab 21 can be straightened to improve the correction quality.

[0118] like Figure 9and Figure 10 As shown, in some embodiments, the end of the pushing portion 71 close to the tab 21 is arc-shaped.

[0119] The end of the pushing portion 71 close to the tab 21 is set to be arc-shaped, which can reduce the pressure between the end 72 and the tab 21 when pushing the tab 21, thereby preventing the tab 21 from being damaged.

[0120] like Figures 9 to 12 As shown, in some embodiments, the correction system further includes a detection device 6 arranged corresponding to the pole tab 21 for detecting the pole tab 21, and the detection device 6 is located upstream of the pushing component 7 in the conveying direction.

[0121] In some embodiments, the detection device 6 is a fiber optic detection mechanism that can detect the position of the tab 21 to improve the correction effect of the correction system. In other embodiments, the detection device 6 can also be an image detection mechanism that can determine the position and angle of the tab 21 by taking a picture of the tab 21.

[0122] In the conveying direction, the detection device 6 is located upstream of the pushing assembly 7 , that is, during the conveying process, the cylindrical battery 2 is first inspected by the detection device 6 and then pushed by the pushing mechanism 7 to push the tab 21 .

[0123] By setting up the detection device 6, the position of the tab can be detected to ensure that the cylindrical battery 2 rotates to the position corresponding to the tab 21 and the pushing portion 71, and at this time the pushing portion 71 can push the tab 21 away from the axis of the cylindrical battery 2 in the radial direction of the cylindrical battery 2 to improve the correction effect.

[0124] like Figure 9 As shown, in some embodiments, the correcting assembly 4 includes a base 42 , the correcting wheel 41 is movably disposed on the base 42 , and the first driving unit 51 drives the correcting wheel 41 to move relative to the base 42 .

[0125] By providing the base 42 and fixing the base 42 , the first driving unit 51 drives the correcting wheel 41 to move so that the correcting wheel 41 can be moved closer to or away from the cylindrical battery 2 .

[0126] like Figure 13 As shown, in some embodiments, the correction system includes: the above-mentioned conveying line and two correction components 4, and the pushing component 7 is arranged between the two correction components 4 along the conveying direction.

[0127] The pushing component 7 is set between the two correcting components 4. After the cylindrical battery 2 is corrected once, the inclined tab 21 can be pushed to the correct position by the pushing component 7, and then the second correction is performed by the correcting component 4, which can improve the correction accuracy.

[0128] Specifically, such as Figures 1 to 13 As shown, during loading, the protrusion 31 passes through the guide portion 321 along the first direction X and drives the first clamping portion 11 away from the second clamping portion 12. The accommodating portion 13 is enlarged so that the cylindrical battery 2 can be placed therein. The protrusion 31 continues to pass through the guide portion 321 along the first direction X. The first clamping portion 11 is driven by the elastic force of the elastic member 13 to approach the second clamping portion 12, thereby clamping the cylindrical battery 2 and completing the loading of the cylindrical battery 2.

[0129] During the correction, the second drive unit 52 drives the correction wheel 41 to rotate. At the same time, the first drive unit 51 drives the correction wheel 41 to approach the cylindrical battery 2, so that the cylindrical battery 2 is clamped between the correction wheel 41 and the first clamping part 11, thereby causing the correction wheel 41 to drive the cylindrical battery 2 to rotate. Subsequently, the detection device 6 detects the position of the tab, so that the cylindrical battery 2 stops rotating after the tab 21 rotates to the position corresponding to the push unit 71, completing the first correction of the tab 21. At this time, the push unit 71 can push the tab 21 away from the axis of the cylindrical battery 2 in the radial direction of the cylindrical battery 2, preventing the tab 21 from tilting toward the axis of the cylindrical battery 2. Finally, the correction wheel 41 drives the cylindrical battery 2 to rotate again, so that the tab 41 returns to the correct angle under the action of centrifugal force, completing the second correction of the tab 21.

[0130] During unloading, the protrusion 31 passes through the guide portion 321 along the first direction X and drives the first clamping portion 11 away from the second clamping portion 12 . The accommodating portion 13 first expands and releases the cylindrical battery 2 , completing unloading of the cylindrical battery 2 .

[0131] The technical features of the above-mentioned embodiments can be combined arbitrarily. 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.

[0132] The above-described embodiments merely represent several implementations of the present invention. 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. Therefore, the scope of protection of the present utility model patent shall be determined by the appended claims.
