[0035] Various exemplary embodiments of the present invention will now be described in detail with reference to the accompanying drawings. It should be noted that unless otherwise specifically stated, the relative arrangements of components and steps, numerical expressions and numerical values ​​set forth in these embodiments do not limit the scope of the present invention.

[0036] The following description of at least one exemplary embodiment is merely illustrative in nature and is in no way intended to limit the present invention, its application, or uses.

[0037] Technologies, methods, and equipment known to ordinary technicians in the relevant art may not be discussed in detail, but where appropriate, the technologies, methods, and equipment should be considered part of the specification.

[0038] In all examples shown and discussed herein, any specific values ​​should be interpreted as merely exemplary and not limiting. Therefore, other examples of the exemplary embodiments may have different values.

[0039] It should be noted that like reference numerals and letters refer to like items in the following figures, and therefore, once an item is defined in one figure, it need not be further discussed in subsequent figures.

[0040] The following first describes in detail the deviation correction device according to an embodiment of the utility model with reference to the accompanying drawings.

[0041] like Figures 1 to 5 As shown, the correction device according to the embodiment of the present invention includes: a correction wheel 10 and a driving unit 20.

[0042] Specifically, the outer circumferential surface of the correcting wheel 10 is suitable for cooperating with the outer circumferential surface of the cylindrical battery 200. The outer circumferential surface of the correcting wheel 10 is provided with a recessed portion 11, which is suitable for accommodating electrolyte. The driving unit 20 is connected to the correcting wheel 10, and the driving unit 20 is suitable for driving the correcting wheel 10 to rotate around its own axis, so that the correcting wheel 10 drives the cylindrical battery 200 to rotate.

[0043] In other words, if Figures 1 to 5 As shown, the correcting device according to an embodiment of the present invention is primarily used to drive a cylindrical battery 200 to rotate about its own axis to adjust the orientation of the tabs on the ends of the cylindrical battery 200, thereby correcting the cylindrical battery 200. The correcting device primarily comprises a correcting wheel 10 and a drive unit 20. One end of the correcting wheel 10 is connected to the output end of the drive unit 20, enabling the drive unit 20 to drive the correcting wheel 10. When correcting the cylindrical battery 200, the axis of the correcting wheel 10 is parallel to the axis of the cylindrical battery 200. The cylindrical battery 200 can freely rotate about its own axis at a set position. The outer circumference of the correcting wheel 10 contacts and engages with the outer circumference of the cylindrical battery 200. When the drive unit 20 drives the correcting wheel 10 to rotate, the correcting wheel 10 can drive the cylindrical battery 200 to rotate about its axis to a desired angle, thereby correcting the cylindrical battery 200.

[0044] In related art, after injecting electrolyte into a cylindrical battery 200, some residual electrolyte may remain on the outer circumference of the battery. During the battery correction operation, this residual electrolyte may remain between the outer circumference of the correction wheel 10 and the outer circumference of the cylindrical battery 200. If there is too much electrolyte between the correction wheel 10 and the cylindrical battery 200, it may cause slippage between the correction wheel 10 and the cylindrical battery 200, making it difficult to adjust the tabs on the cylindrical battery 200 to the desired orientation.

[0045] Based on this, Figures 1 to 4As shown, the deflection correction device of an embodiment of the present invention is provided with one or more recessed portions 11 on the outer circumference of the deflection correction wheel 10. When the deflection correction wheel 10 is pressed against the outer circumference of the cylindrical battery 200, the residual electrolyte on the outer circumference of the cylindrical battery 200 is squeezed into these recessed portions 11. These recessed portions 11 can temporarily store the electrolyte, ensuring close contact between the cylindrical battery 200 and the deflection correction wheel 10, effectively preventing slippage, and thus ensuring the accuracy and efficiency of the deflection correction operation.

[0046] Therefore, according to the correction device provided in this embodiment, a recessed portion 11 suitable for accommodating electrolyte is provided on the outer peripheral surface of the correction wheel 10, so that when the outer peripheral surface of the correction wheel 10 contacts the outer peripheral surface of the cylindrical battery 200, the residual electrolyte on the outer peripheral surface of the cylindrical battery 200 will be squeezed into the recessed portion 11, thereby effectively avoiding the interference of the electrolyte on the correction process, ensuring that the correction wheel 10 and the cylindrical battery 200 can maintain stable and close contact, effectively avoiding slipping, and significantly improving the accuracy and efficiency of the correction operation.

[0047] In some embodiments of the present invention, the recessed portion 11 is formed as a groove extending along the circumference of the correcting wheel 10 .

[0048] That is to say, if Figure 1 and Figure 4 As shown, the recessed portion 11 is configured as a groove, which can extend along the circumference of the correcting wheel 10 to form an arc groove that is not a closed-loop structure, or form an annular groove with a closed-loop structure, so as to facilitate the recessed portion 11 to accommodate electrolyte at different positions of the circumference of the correcting wheel 10, thereby reducing the accumulation of electrolyte between the outer peripheral surface of the correcting wheel 10 and the outer peripheral surface of the cylindrical battery 200, and thus effectively avoiding the interference of the electrolyte on the correction process, which can further improve the stability and accuracy of the correction operation.

[0049] According to one embodiment of the present invention, the recessed portion 11 is formed as an annular groove surrounding the outer circumference of the deviation correcting wheel 10 .

[0050] In other words, if Figure 1 and Figure 4 As shown, the recessed portion 11 can be a groove provided on the outer peripheral surface of the correcting wheel 10, and the groove can extend along the circumference of the correcting wheel 10 to form an annular groove, so that the recessed portion 11 can accommodate electrolyte at any position of the circumference of the correcting wheel 10, which can further reduce the accumulation of electrolyte between the outer peripheral surface of the correcting wheel 10 and the outer peripheral surface of the cylindrical battery 200, thereby effectively avoiding the interference of the electrolyte on the correction process, and further improving the stability and accuracy of the correction operation.

[0051] In some embodiments of the present invention, the outer peripheral surface of the correcting wheel 10 is provided with a plurality of recessed portions 11, wherein at least some of the recessed portions 11 are distributed along the axial direction of the correcting wheel 10, and / or at least some of the plurality of recessed portions 11 are distributed along the circumferential direction of the correcting wheel 10.

[0052] Specifically, if Figure 1 and Figure 4 As shown, the outer peripheral surface of the correcting wheel 10 may have two or more recessed portions 11. For example, when the recessed portion 11 is an arc-shaped groove extending along the circumference of the correcting wheel 10, the distribution of the plurality of recessed portions 11 includes but is not limited to the following situations:

[0053] Case 1: Multiple recessed portions 11 may be distributed along the circumference of the correcting wheel 10;

[0054] Case 2: Multiple recessed portions 11 may be distributed along the axial direction of the correcting wheel 10;

[0055] Case 3: A portion of the recessed portions 11 may be distributed along the circumference of the correcting wheel 10 , and another portion of the recessed portions 11 may be distributed along the axial direction of the correcting wheel 10 .

[0056] When the recessed portion 11 is formed as an annular groove surrounding the outer circumference of the correcting wheel 10 , a plurality of recessed portions 11 may be distributed along the axial direction of the correcting wheel 10 .

[0057] Therefore, according to the correction device of the present invention, the multiple recessed portions 11 can accommodate electrolyte at different positions, which is beneficial to reducing the accumulation of electrolyte between the outer peripheral surface of the correction wheel 10 and the outer peripheral surface of the cylindrical battery 200, thereby effectively avoiding the interference of the electrolyte on the correction process.

[0058] According to one embodiment of the present invention, a plurality of recessed portions 11 are spaced apart and distributed along the axial direction of the correcting wheel 10 .

[0059] That is to say, multiple recesses 11 can be distributed at intervals along the axial direction of the correction wheel 10. The axially distributed recesses 11 can more effectively capture and accommodate residual electrolyte on the outer peripheral surface of the battery, reduce the impact of the electrolyte on the contact surface between the correction wheel 10 and the battery, and improve the stability and accuracy of the correction operation.

[0060] In some embodiments of the present invention, the dimension of the recessed portion 11 in the axial direction of the correcting wheel 10 is smaller than half the dimension of the outer peripheral surface of the correcting wheel 10 in the axial direction of the correcting wheel 10 .

[0061] In this embodiment, the dimensions of all axial recesses 11 of the correcting wheel 10 are less than half the axial dimension of the outer circumference of the correcting wheel 10. This ensures sufficient contact area between the correcting wheel 10 and the cylindrical battery 200, effectively preventing slippage and ensuring the stability and accuracy of the correction. Furthermore, this design facilitates more even force distribution between the correcting wheel 10 and the battery, reducing battery damage or wear on the correcting wheel 10 caused by uneven contact.

[0062] According to one embodiment of the present invention, the correction device includes one or more correction wheels 10, and the driving unit 20 is suitable for driving the one or more correction wheels 10 to rotate. The correction device also includes: a base 30, the driving unit 20 is arranged on the base 30, and the correction wheel 10 is rotatably arranged on the base 30 around its own axis.

[0063] In other words, the correction device according to the embodiment of the present invention mainly includes one or more correction wheels 10, a drive unit 20 and a base 30, wherein the base 30 can provide an installation position for the correction wheel 10 and the drive unit 20, and each correction wheel 10 is fixedly connected with a connecting shaft, and the connecting shaft is rotatably connected to the base 30 around the axis of the corresponding correction wheel 10.

[0064] In one example, the correction device includes a plurality of correction wheels 10, which are distributed at intervals along the radial direction of the correction wheel 10, and the driving unit 20 includes a plurality of motors, the number and position of the motors and the correction wheels 10 correspond one to one, the motors are fixedly connected to the base 30, and the output end of the motor is fixedly connected to the connecting shaft on the corresponding correction wheel 10 through a coupling, so that the motor can drive the corresponding correction wheel 10 to rotate one by one, so that the correction device can correct multiple cylindrical batteries 200 at the same time, thereby improving the correction efficiency.

[0065] In another example, the correction device includes a correction wheel 10, and the driving unit 20 includes a motor, which is fixedly connected to the base 30. The output end of the motor is fixedly connected to the connecting shaft on the correction wheel 10 through a coupling, so that the motor can drive the correction wheel 10 to rotate, and the structure is simple.

[0066] In some embodiments of the present invention, the deviation-correcting device further includes: a cleaning component 40 , which is disposed on the base 30 and is suitable for cleaning the outer peripheral surface of the deviation-correcting wheel 10 .

[0067] During operation, some dust (eg, dust and other particulate matter) may gradually accumulate on the surface of the correcting wheel 10. If not cleaned in time, the dust may scratch the battery surface and affect the battery quality and performance.

[0068] Based on this, Figures 1 to 3As shown, the correcting device is provided with a cleaning assembly 40 , which may correspond to the number and position of the correcting wheels 10 , and the cleaning assembly 40 is mounted on the base 30 , and the cleaning assembly 40 may be located on the side of the correcting wheel 10 away from the cylindrical battery 200 .

[0069] In this embodiment, the correction device is equipped with a cleaning assembly 40 to clean the outer circumference of the correction wheel 10, including not only the surface in direct contact with the cylindrical battery 200 but also the walls of the recess 11. The cleaning assembly 40 removes dust adhering to the outer circumference of the correction wheel 10, ensuring the cleanliness of the contact surface between the correction wheel 10 and the battery. This cleaning mechanism significantly reduces the risk of scratches on the battery surface caused by particulate matter, thereby enhancing the safety and reliability of the correction process.

[0070] In an embodiment, the cleaning assembly 40 can be provided to clean the outer peripheral surface of the correcting wheel 10 (ie, the surface of the correcting wheel 10 in contact with the cylindrical battery 200 and the wall surface of the recessed portion 11 ).

[0071] In one example, the cleaning assembly 40 removes dust adhering to the outer circumference of the correcting wheel 10, ensuring the cleanliness of the contact surface between the correcting wheel 10 and the battery. This cleaning mechanism significantly reduces the risk of scratches on the battery surface caused by particulate matter, thereby enhancing the safety and reliability of the correction process.

[0072] In another example, the cleaning component 40 can remove the electrolyte and dust contained in the groove portion, thereby ensuring that the groove portion continues to store the electrolyte when the correction wheel 10 contacts the cylindrical battery 200, thereby ensuring close contact between the battery and the correction wheel 10 and ensuring the reliability of the correction process.

[0073] According to one embodiment of the present invention, the cleaning component 40 includes: a brush 41 and a negative pressure adsorption tube 42. The brush 41 is provided on the base 30. The brush 41 is suitable for cleaning the outer peripheral surface of the correcting wheel 10 when the correcting wheel 10 rotates. The negative pressure adsorption tube 42 is provided on the base 30. The negative pressure adsorption tube 42 is located on the side of the correcting wheel 10 close to the brush 41. The negative pressure adsorption tube 42 is suitable for adsorbing dust and / or electrolyte.

[0074] That is to say, if Figure 3 and Figure 5 As shown, the cleaning assembly 40 primarily includes a brush 41 and a negative pressure adsorption tube 42. The brush 41 can be positioned on the side of the correcting wheel 10 away from the cylindrical battery 200. The brush 41 can be fixed to the base 30, and the bristles of the brush 41 can contact the outer circumference of the correcting wheel 10. As the correcting wheel 10 rotates, the bristles can effectively remove dust and electrolyte from the outer circumference. This design eliminates the need for an additional drive mechanism, making the cleaning assembly 40 more simple in structure.

[0075] The negative pressure adsorption tube 42 can be arranged on the same side of the correction wheel 10 as the brush 41, with the first end of the negative pressure adsorption tube 42 facing the outer peripheral surface of the correction wheel 10. When in use, the second end of the negative pressure adsorption tube 42 can be connected to a negative pressure generator (for example, a vacuum cleaner), so that the dust and electrolyte brushed off by the brush 41 can be adsorbed through the second end of the negative pressure adsorption tube 42, and the dust and electrolyte on the outer peripheral surface of the correction wheel 10 can be adsorbed.

[0076] In this embodiment, taking into account the viscous properties of the electrolyte, the cleaning process first uses a brush 41 for physical cleaning, and then removes dust through a negative pressure adsorption tube 42. This two-step cleaning mechanism can effectively remove the electrolyte and dust adhering to the outer peripheral surface of the correction wheel 10, thereby ensuring the cleaning effect of the cleaning component 40, and can effectively prevent the electrolyte and dust brushed off by the wall brush 41 from being redeposited on the surface of the correction wheel 10 or diffused into the environment, thereby improving the cleaning efficiency.

[0077] In some embodiments of the present invention, the brush 41 is disposed on the inner side of the negative pressure adsorption tube 42 , and a portion of the deviation-correcting wheel 10 extends into the negative pressure adsorption tube 42 and fits against the brush 41 .

[0078] Specifically, if Figure 3 and Figure 5 As shown, the brush 41 is fixedly mounted on the inside of the negative pressure adsorption tube 42. To ensure that the bristles of the brush 41 can effectively contact the correcting wheel 10, the area of ​​the correcting wheel 10 near the brush 41 is designed to extend into the interior of the negative pressure adsorption tube 42 and maintain close contact with the bristles of the brush 41. This configuration enables the negative pressure adsorption tube 42 to quickly absorb dust and electrolyte removed by the brush 41, effectively preventing these contaminants from redepositing on the surface of the correcting wheel 10 or dispersing into the surrounding environment, thereby improving cleaning efficiency.

[0079] like Figure 6 and Figure 7 As shown, an embodiment of the present invention further provides a correction device 100, including the correction device described in any of the above embodiments. Since the correction device according to the embodiment of the present invention has the above technical effects, the correction device 100 according to the embodiment of the present invention also has corresponding technical effects, which will not be described in detail in this embodiment.

[0080] like Figure 6 and Figure 7As shown, in some embodiments of the present invention, the correction device 100 also includes a mounting platform 50, a conveying device 60, a driving device 70 and a detection device 80, wherein the mounting platform 50 and the conveying device 60 are distributed along a first direction, and the correction device is movably arranged on the mounting platform 50 along the first direction through a slider and rail mechanism, and the driving device 70 can be a cylinder, and the driving device 70 is fixedly connected to the mounting platform 50, and the output end of the driving device 70 is fixedly connected to the correction device, so that the correction device can be driven to move along the first direction by the driving device 70, so that the correction wheel 10 can approach or move away from the cylindrical battery 200 on the conveying device 60.

[0081] like Figure 6 and Figure 7 As shown, the conveying device 60 is provided with a plurality of battery placement positions suitable for accommodating cylindrical batteries 200 on the side close to the correction wheel 10, and the conveying device 60 is provided with two support shafts 61 rotatable around their own axes on the side close to the correction wheel 10. The outer circumferences of the two support shafts 61 can be in contact with the outer circumferences of the cylindrical batteries 200. The conveying device 60 can control its movement through a conveyor belt and can transport the cylindrical batteries 200 to the correction station. The detection device 80 can be a CCD visual detection element or other element such as an optical fiber sensor. The detection device 80 is fixedly mounted on the mounting platform 50 and is located above the conveying device 60. The detection device 80 can detect whether the tabs at the upper end of the cylindrical battery 200 are facing in the correct direction.

[0082] like Figure 6 and Figure 7 As shown, when the correction device 100 according to the embodiment of the present invention is in use, the conveying device 60 conveys the cylindrical battery 200 to the correction station. At this time, the cylindrical battery 200 corresponds to the position of the correction wheel 10 and the detection device 80. The cylindrical battery 200 and the correction wheel 10 are spaced apart in the first direction, and the tab end of the cylindrical battery 200 faces the detection device 80; the detection device 80 can detect the tab direction of the cylindrical battery 200 at the correction station. If the tab direction needs to be adjusted, the driving device 70 drives the correction wheel 10 close to the cylindrical battery 200. Battery 200, so that the outer circumferential surface of the correcting wheel 10 is in close contact with the outer circumferential surface of the cylindrical battery 200, and the radial position of the cylindrical battery 200 can be limited by cooperating with the support shaft 61 on the conveying device 60, and then the correcting wheel 10 is driven to rotate by the driving unit 20, and the rotation of the correcting wheel 10 drives the cylindrical battery 200 to rotate. During the rotation of the battery, the direction of the battery tab is detected by the detection device 80 until the direction of the tab is correct and the correcting wheel 10 stops rotating. Finally, the driving unit 20 drives the correcting device away from the cylindrical battery 200.
