Description

Technical Field

[0001] The utility model relates to the technical field of battery manufacturing equipment, in particular to a winding arm mechanism, a winding device and a slitting machine. Background Art

[0002] In the battery manufacturing process, the incoming separator material needs to be cut and the multiple strips formed by cutting need to be rolled up separately using a winding assembly. Figure 1 As shown, in the prior art, the winding device includes a plurality of winding arm mechanisms arranged side by side, each winding arm mechanism winding a sub-material strip. The winding arm mechanism uses a motor to drive the winding shaft to rotate, thereby driving the barrel on the winding shaft to rotate, and then winding the sub-material strip onto the barrel (the sub-material strip wound on the barrel forms a roll).

[0003] Since the axial directions of the output shaft of the motor and the winding shaft are consistent, the motor needs to occupy the space between the two adjacent winding arm mechanisms. On the one hand, this will result in the spacing between the two adjacent winding arm mechanisms not being too narrow, which in turn makes it impossible to wind up sub-material strips with smaller widths, such as being unable to wind up sub-material strips with a width of less than 65mm. On the other hand, since the space between the two adjacent winding arm mechanisms is narrow, only motors with smaller power can be used, resulting in the motor providing a smaller torque, which is unable to meet the winding requirements of sub-material strips with larger widths, such as being unable to meet the winding requirements of sub-material strips with a width of more than 350mm. Utility Model Content

On the one hand, this will result in the spacing between the two adjacent winding arm mechanisms not being too narrow, which in turn will lead to the inability to meet the winding needs of sub-material strips with smaller widths; on the other hand, due to the narrow space between the two adjacent winding arm mechanisms, only motors with smaller power can be used, resulting in the motor providing a smaller torque, which is unable to meet the winding needs of sub-material strips with larger widths.

[0032] In addition, the terms "first" and "second" are used for descriptive purposes only and should not be understood as indicating or implying relative importance or implicitly indicating the number of the indicated technical features. Therefore, the features defined as "first" and "second" may explicitly or implicitly include at least one of the features. In the description of the present utility model, the meaning of "plurality" is at least two, such as two, three, etc., unless otherwise clearly and specifically defined.

[0033] In the present invention, unless otherwise clearly specified and limited, the terms "installed", "connected", "connected", "fixed" and the like should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium, it can be the internal connection of two elements or the interaction relationship between two elements, unless otherwise clearly defined. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0035] It should be noted that when an element is referred to as being "fixed to" or "disposed on" another element, it may be directly on the other element or there may be a central element. When an element is considered to be "connected to" another element, it may be directly connected to the other element or there may be a central element at the same time.

[0036] See also Figure 2 and Figure 3 The utility model provides a slitting machine in one embodiment, including a slitting device and a winding device 1, wherein the slitting device is used to slit a material strip and form a plurality of sub-material strips. The winding device 1 includes a plurality of winding arm mechanisms 10 (see Figure 3 ), each winding arm mechanism 10 is arranged at intervals along a first direction X1, and the first direction X1 is consistent with the width direction of each sub-material strip. Each winding arm mechanism 10 is used to wind up a corresponding sub-material strip. It should be noted that the material strip can be a diaphragm. Of course, in other embodiments, it can also be other material strips that need to be cut, which is not limited here.

[0037] It should be noted that the roll A formed by the reeling arm mechanism 10 reeling up the sub-material strip is located between two adjacent reeling arm mechanisms 10, that is, the space between the two adjacent reeling arm mechanisms 10 is used to accommodate the roll A. Therefore, the smaller the minimum value of the adjustable spacing between the two adjacent reeling arm mechanisms 10, the smaller the width of the roll A that can be accommodated between the two adjacent reeling arm mechanisms 10, that is, the smaller the width of the reel that can be reeled up. In other words, the smaller the minimum value of the adjustable spacing between the two adjacent reeling arm mechanisms 10, the smaller the width of the sub-material strip that can be reeled up can be accommodated, making the reeling device 1 more compatible.

[0038] Please also see Figure 4 and Figure 5In the embodiment of the present application, the winding arm mechanism 10 includes a mounting seat 11, a winding arm 12, a winding shaft 13, a driving motor 14 and a transmission assembly (not shown). One end of the winding arm 12 is arranged on the mounting seat 11, and the winding shaft 13 is rotatably connected to the other end of the winding arm 12. The driving motor 14 is mounted on the mounting seat 11, and the output shaft of the driving motor 14 is perpendicular to the winding shaft 13, and the first direction X1 is parallel to the winding shaft 13. The transmission assembly is connected between the output shaft of the driving motor 14 and the winding shaft 13, so that the output shaft of the driving motor 14 can drive the winding shaft 13 to rotate through the transmission assembly, thereby enabling the winding shaft 13 to achieve the winding of the sub-material strip. It should be noted that since the output shaft of the driving motor 14 is perpendicular to the winding shaft 13, the transmission assembly needs to realize right-angle transmission, that is, the rotational motion of the output shaft of the driving motor 14 is converted into the rotational motion of the winding shaft 13 perpendicular thereto.

[0039] In the above winding device 1, the axial direction of the output shaft of the driving motor 14 is the length direction of the driving motor 14. Since the output shaft of the driving motor 14 is perpendicular to the winding shaft 13, that is, the length direction of the driving motor 14 is perpendicular to the winding shaft 13. Each winding arm mechanism 10 is arranged at intervals along the first direction X1 parallel to the axial direction of the winding shaft 13. Since the length direction of the driving motor 14 is perpendicular to the winding shaft 13, the driving motor 14 does not occupy the space on both sides of the winding arm mechanism 10 in the first direction X1, that is, the driving motor 14 does not occupy the space between two adjacent winding arm mechanisms 10. On the one hand, each winding arm mechanism 10 can be as close as possible, so that the winding shaft 13 can wind up a sub-material strip with a smaller width; on the other hand, the installation space of the driving motor 14 is not limited by the narrow space between the two adjacent winding arm mechanisms 10, and a driving motor 14 with a larger power can be installed, so that a larger torque can be output to drive the winding shaft 13 to wind up a sub-material strip with a wider width, which greatly expands the compatibility of the winding device 1.

[0040] Figure 1 In the prior art, only a small motor of 100W can be used, which can only meet the requirements of winding sub-strips with a width of 65mm to 250mm. However, the drive motor 14 in the winding device 1 of the present application can use a large motor of 400W, which can meet the requirements of winding sub-strips with a width of 46mm to 400mm. In other words, compared with the prior art, the winding device 1 in the present application can wind sub-strips with a wider range of widths and stronger compatibility.

[0041] It should be noted that the drive motor 14 has a torque monitoring function, so that the power output can be adjusted according to the torque change to ensure that the tension of the sub-strip can remain stable during the winding process, which is beneficial to improving the winding quality.

[0042] It should also be noted that the term "perpendicular" in this article should be understood as allowing a certain error, as long as it is roughly perpendicular. The term "parallel" in this article should be understood as allowing a certain error, as long as it is roughly parallel.

[0043] Specifically in the embodiment, the winding device 1 also includes a base 20 (see Figure 3 ), the mounting seat 11 of each winding arm mechanism 10 is arranged on the base 20, and each mounting seat 11 can be controlled to move along the first direction X1 relative to the base 20. In this way, by controlling each mounting seat 11 to move along the first direction X1 relative to the base 20, the spacing between each winding arm 12 can be adjusted to wind up the sub-material strips with different widths.

[0044] It should be noted that each mounting seat 11 is equipped with a linear drive member, which is used to drive the corresponding mounting seat 11 to move relative to the base 20 along the first direction X1, so as to adjust the spacing between each winding arm 12. The linear drive member can be a linear drive module such as an electric cylinder or a linear motor, as long as it can achieve that each mounting seat 11 can move independently relative to the base 20 along the first direction X1, and is not limited here.

[0045] In an embodiment of the present application, the transmission assembly includes a right-angle transmission unit 151, a parallel transmission unit 153, and a rotating shaft 152 rotatably connected to the mounting seat 11. The rotating shaft 152 is perpendicular to the output shaft of the driving motor 14 and parallel to the winding shaft 13, that is, the axial direction of the rotating shaft 152 is parallel to the first direction X1. The right-angle transmission unit 151 is transmission-connected between the output shaft of the driving motor 14 and the rotating shaft 152, and is used to transmit the rotational motion of the output shaft of the driving motor 14 to the rotating shaft 152 at a right angle. The parallel transmission unit 153 is transmission-connected between the rotating shaft 152 and the winding shaft 13, and is used to transmit the rotational motion of the rotating shaft 152 to the winding shaft 13 in parallel.

[0046] In some embodiments, the right-angle transmission unit 151 includes an active magnetic wheel 1512 and a driven magnetic wheel 1514. The active magnetic wheel 1512 is coaxially mounted on the output shaft of the drive motor 14 so that it can rotate synchronously with the output shaft of the drive motor 14. The driven magnetic wheel 1514 is coaxially mounted on the rotating shaft 152 so that it can rotate synchronously with the rotating shaft 152. A magnetic transmission is formed between the active magnetic wheel 1512 and the driven magnetic wheel 1514, so that when the active magnetic wheel 1512 rotates following the output shaft of the drive motor 14, it can drive the driven magnetic wheel 1514 to rotate, and the driven magnetic wheel 1514 then drives the rotating shaft 152 to rotate, and the rotating shaft 152 then drives the winding shaft 13 to rotate through the parallel transmission unit 153. In this way, the active magnetic wheel 1512 and the driven magnetic wheel 1514 are used to realize the right-angle transmission between the output shaft of the drive motor 14 and the rotating shaft 152, and the transmission method of the active magnetic wheel 1512 and the driven magnetic wheel 1514 is a non-contact transmission method, which has the advantages of strong power transmission capability, no wear, no dust, no noise, good dynamic balance, high position control accuracy, maintenance-free, and replacement-free.

[0047] It should be noted that the right-angle transmission unit 151 is not limited to the non-contact magnetic transmission method. In other embodiments, the right-angle transmission unit 151 can also adopt a contact transmission method of a worm gear and a worm. Specifically, the right-angle transmission unit 151 includes a worm and a worm wheel. The worm is coaxially mounted on the output shaft of the drive motor 14, so that the worm can rotate with the output shaft of the drive motor 14. The worm wheel is coaxially mounted on the rotating shaft 152, so that the worm wheel and the rotating shaft 152 can rotate synchronously. The worm is meshed with the worm wheel, so that when the worm rotates with the output shaft of the drive motor 14, the worm wheel can drive the worm wheel to rotate, and the worm wheel then drives the rotating shaft 152 to rotate, so that the rotating shaft 152 drives the winding shaft 13 to rotate through the parallel transmission unit 153. In other words, the right-angle transmission between the output shaft of the drive motor 14 and the rotating shaft 152 is realized by using the worm and the worm wheel.

[0048] In some other embodiments, the right-angle transmission unit 151 includes a driving bevel gear and a driven bevel gear. The driving bevel gear is coaxially mounted on the output shaft of the driving motor 14, so that the driving bevel gear can rotate together with the output shaft of the driving motor 14. The driven bevel gear is coaxially mounted on the rotating shaft 152, so that the driven bevel gear and the rotating shaft 152 can rotate synchronously. The driving bevel gear is meshed with the driven bevel gear, so that the driving bevel gear can drive the driven bevel gear to rotate when the output shaft of the driving motor 14 rotates, and the driven bevel gear then drives the rotating shaft 152 to rotate, and the rotating shaft 152 then drives the winding shaft 13 to rotate through the parallel transmission unit 153. In other words, the driving bevel gear and the driven bevel gear are used to realize the right-angle transmission between the output shaft of the driving motor 14 and the rotating shaft 152.

[0049] Specifically in the embodiment, the parallel transmission unit 153 includes a driving wheel (not shown), a driven wheel (not shown) and a transmission belt 1533. The driving wheel is coaxially mounted on the rotating shaft 152, so that the driving wheel can rotate together with the rotating shaft 152. The driven wheel is coaxially mounted on the winding shaft 13, so that the driven wheel and the winding shaft 13 can rotate synchronously. The transmission belt 1533 is sleeved between the driving wheel and the driven wheel, so that when the driving wheel rotates with the rotating shaft 152, the driven wheel can drive the driven wheel to rotate through the transmission belt 1533, and the driven wheel then drives the winding shaft 13 to rotate. In other words, the parallel transmission between the rotating shaft 152 and the winding shaft 13 is realized by using the driving wheel, the transmission belt 1533 and the driven wheel.

[0050] In the embodiment of the present application, the drive motor 14 is located on one side of the winding arm 12 in the second direction X2, and the second direction X2 is parallel to the output shaft of the drive motor 14 and perpendicular to the winding shaft 13. In this way, the drive motor 14 is arranged in the space on one side of the winding arm 12 in the second direction X2, so that the drive motor 14 is prevented from occupying the space on both sides of the winding arm 12 in the first direction X1, that is, the drive motor 14 is prevented from occupying the space between two adjacent winding arms 12. On the one hand, each winding arm mechanism 10 can be as close as possible, so that a sub-material strip with a smaller width can be wound; on the other hand, the drive motor 14 is not limited by the narrow space between two adjacent winding arm mechanisms 10, and a more powerful drive motor 14 can be installed, so that a greater torque can be output to drive the winding shaft 13 to wind up a wider sub-material strip, which greatly expands the compatibility of the winding device 1.

[0051] Specifically in the embodiment, the end of the winding arm 12 away from the winding shaft 13 is rotatably connected to the mounting seat 11 around a rotation axis. The rotation axis is colinear with the axis of the rotating shaft 152, so as to avoid affecting the transmission of the transmission assembly when the winding arm 12 rotates relative to the mounting seat 11. The winding arm mechanism 10 also includes a swing drive member 16 mounted on the mounting seat 11, and the swing drive member 16 is connected to the winding arm 12 to drive the winding arm 12 to rotate around the rotation axis. Specifically, the end of the winding arm 12 away from the winding shaft 13 is mounted on the rotating shaft 152 through a bearing, so that the rotation of the winding arm 12 and the rotation of the rotating shaft 152 are not affected by each other. Of course, other methods can also be used to install the winding arm 12 and the rotating shaft 152, as long as it is ensured that the two do not affect each other and the rotation axis is colinear with the axis of the rotating shaft 152, which is not limited here.

[0052] Furthermore, the winding device 1 also includes a winding roller 30 for winding a plurality of sub-strips, and each winding arm 12 drives the winding shaft 13 thereon to press against the winding roller 30, and the winding roller 30 applies a pressing force to the material roll A wound on the winding shaft 13. Under the action of the pressing force, the material roll A wound on the winding shaft 13 is more compact. In order to ensure that the compactness of the material roll A is consistent, as the diameter of the material roll A wound on the winding shaft 13 gradually increases, the swing drive member 16 drives the winding arm 12 to rotate, so that the winding arm 12 drives the winding shaft 13 thereon to swing in a direction away from the winding roller 30, thereby ensuring that the pressing force applied by the winding roller 30 on the material roll A remains stable. Optionally, the swing drive member 16 can be a cylinder.

[0053] Specifically in the embodiment, the swing driving member 16 and the driving motor 14 are located on the same side of the winding arm 12 in the second direction X2, and the second direction X2 is parallel to the axial direction of the driving motor 14. In this way, the swing driving member 16 and the driving motor 14 are arranged using the space on one side of the winding arm 12 in the second direction X2. On the one hand, the installation space for arranging the swing driving member 16 and the driving motor 14 is increased, so that a larger swing driving member 16 and a higher-power driving motor 14 can be installed; on the other hand, the swing driving member 16 and the driving motor 14 are prevented from occupying the space on both sides of the winding arm 12 in the first direction X1, that is, the swing driving member 16 and the driving motor 14 are prevented from occupying the narrow space between two adjacent winding arms 12.

[0054] The technical features of the above-described embodiments may be arbitrarily combined. To make the description concise, not all possible combinations of the technical features in the above-described 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.

[0055] The above-mentioned embodiments only express several implementation methods of the utility model, and the description is relatively specific and detailed, but it cannot be understood as limiting the scope of the utility model patent. It should be pointed out that for ordinary technicians in this field, several modifications and improvements can be made without departing from the concept of the utility model, which all belong to the protection scope of the utility model.
