Description

Technical Field

[0001] This application relates to the field of battery winding equipment technology, and in particular to a winding device and a cell winding equipment. Background Technology

[0002] In the process of manufacturing battery cells using winding needles, battery cell winding equipment typically incorporates a roll-changing device to improve production efficiency and prevent downtime. This device holds a spare roll and a working roll. Once the working roll is unwound, the spare roll takes over, allowing for unwinding without interrupting equipment operation and maximizing battery cell manufacturing efficiency. However, the complex structure of these roll-changing devices in related technologies results in high costs. Utility Model Content

[0003] This application discloses a winding device and a cell winding equipment, which enables the winding device to have a simple structure and low cost.

[0004] To achieve the above objectives, in a first aspect, this application discloses a roll-changing device, comprising:

[0005] Unwinding mechanism;

[0006] A cutting and adsorption mechanism, located downstream of the unwinding mechanism; and,

[0007] The tape receiving mechanism includes a motion mechanism, a mounting base, an adsorption component, and a first rotary drive. The mounting base is disposed on the motion mechanism. The adsorption component is rotatably mounted on the mounting base about a first axis. The adsorption component has at least two adsorption surfaces with different orientations. The first rotary drive is disposed on the mounting base and connected to the adsorption component.

[0008] The adsorption assembly is driven to rotate around the first axis by a first rotary drive, so that one of the at least two adsorption surfaces faces the starting end of the spare material roll. Then, a motion mechanism pulls the starting end of the spare material roll to the cutting adsorption mechanism, thus unwinding the spare material roll. Alternatively, the adsorption assembly can be driven to continue rotating around the first axis by the first rotary drive, so that the other adsorption surface faces the starting end of the spare material roll. Then, a motion mechanism moves this adsorption surface closer to the starting end of the spare material roll, so that the starting end of the spare material roll and the downstream cut end of the working material roll are joined together by the tape on the adsorption surface, thus achieving the tape splicing function. In other words, each of the at least two adsorption surfaces of the same adsorption assembly can perform a different function; that is, the same adsorption assembly integrates at least two functions. Therefore, the structure of the roll-changing device can be simplified to a certain extent, reducing its cost.

[0009] Optionally, the adsorption component includes:

[0010] A rotating shaft, rotatably mounted on the mounting base about the first axis, the first rotation drive member being connected to the rotating shaft; and...

[0011] At least two adsorption elements are provided on the rotating shaft, and at least two adsorption surfaces correspond one-to-one with at least two adsorption elements. Each adsorption element has an adsorption surface formed on it.

[0012] Since the rotating shaft is rotatably mounted on the mounting base about the first axis, and the first rotating drive is connected to the rotating shaft, the first rotating drive can drive the rotating shaft to rotate about the first axis.

[0013] When the rotating shaft rotates around the first axis, since at least two adsorption elements are disposed on the rotating shaft, at least two adsorption elements can be driven to rotate around the first axis. When at least two adsorption elements rotate around the first axis, since at least two adsorption surfaces correspond one-to-one with at least two adsorption elements, and each adsorption surface is formed on the corresponding adsorption element, at least two adsorption surfaces can be driven to rotate around the first axis, thereby achieving the purpose of adjusting the orientation of the adsorption surfaces.

[0014] Since at least two adsorption surfaces correspond one-to-one with at least two adsorption elements, and each adsorption surface is formed on the corresponding adsorption element, the at least two adsorption surfaces can be made independent, thereby avoiding the situation where the at least two adsorption surfaces affect each other.

[0015] Optionally, the adsorption component includes:

[0016] A rotating shaft is rotatably mounted on the mounting base about the first axis, the first rotating drive is connected to the rotating shaft, and the rotating shaft is provided with at least two adsorption surfaces.

[0017] Optionally, at least two of the adsorption elements are distributed around the first axis, and the adsorption surface is located on the side of the corresponding adsorption element opposite to the first axis.

[0018] By positioning the adsorption surface on the side of the corresponding adsorption element away from the first axis, the adsorption surface can be located on the outside of the adsorption element. This avoids interference between the adsorption element and the adsorption surface, allowing for more reliable and stable adsorption.

[0019] In addition, by distributing at least two adsorption elements around the first axis, the adsorption surfaces on at least two adsorption elements can rotate around the first axis during the rotation of the rotating shaft around the first axis, thereby allowing for very flexible adjustment of the orientation of the adsorption surfaces.

[0020] Optionally, the at least two adsorption elements include:

[0021] First adsorption element; and,

[0022] The second adsorption element is arranged adjacent to the first adsorption element and the second adsorption element in the circumferential direction along the rotation axis.

[0023] Optionally, the first rotary drive is used to drive the adsorption assembly to rotate around the first axis, so that the adsorption surface of the first adsorption member faces the spare roll and the adsorption surface of the second adsorption member faces the cutting and adsorption mechanism, respectively.

[0024] When the adsorption surface of the first adsorption element faces the spare material roll, it is convenient to pick up the starting end of the spare material roll at the spare material roll through the adsorption surface of the first adsorption element and pull the starting end to the cutting adsorption mechanism. When the adsorption surface of the second adsorption element faces the cutting adsorption mechanism, it is convenient to adhere the tape on the adsorption surface of the second adsorption element to the starting end of the spare material roll and the material strip of the working material roll located at the cutting adsorption mechanism.

[0025] Optionally, the at least two adsorption elements further include:

[0026] The third adsorption element, wherein the first rotary drive element is further configured to drive the adsorption assembly to rotate about the first axis, so that the adsorption surface of the third adsorption element faces the cutting adsorption mechanism.

[0027] Optionally, the at least two adsorption elements further include:

[0028] A fourth adsorption element is disposed opposite to the first adsorption element, and the second adsorption element is disposed opposite to the third adsorption element. The fourth adsorption element and the third adsorption element are disposed adjacent to each other along the circumferential direction of the rotation axis.

[0029] Optionally, the first rotary drive is further configured to drive the adsorption assembly to rotate around the first axis so that the adsorption surface of the fourth adsorption member faces the working material roll, and the motion mechanism is further configured to drive the adsorption assembly to move so as to adhere the tape on the fourth adsorption member to the remaining tape in the working material roll.

[0030] Optionally, the strapping mechanism further includes:

[0031] A first driving assembly, comprising at least two adsorption elements including a fourth adsorption element, wherein the first driving assembly is connected to the fourth adsorption element.

[0032] Optionally, the first driving component is used to drive the fourth adsorption element to slide.

[0033] When the tape receiving mechanism also includes a first drive assembly, in addition to driving the fourth adsorption member to move toward the working roll via the motion mechanism, the fourth adsorption member can also be driven to slide toward the working roll along the first radial direction of the rotating shaft via the first drive assembly. Therefore, on the one hand, the efficiency of the fourth adsorption member moving toward the working roll can be improved, and on the other hand, the rotating shaft can be made to be farther away from the first unwinding shaft along the first radial direction, thereby avoiding interference between the rotating shaft and the first unwinding shaft or other components in the roll changing device.

[0034] Optionally, the first driving component includes:

[0035] A lead screw, which extends axially along the rotating shaft and is rotatably mounted within the rotating shaft;

[0036] A second rotary drive component is disposed on the mounting base and connected to the lead screw;

[0037] A transmission nut, which is sleeved on the lead screw and slidably disposed along the axial direction of the rotation axis, and a fourth adsorption member, which is slidably disposed;

[0038] A connecting rod, one end of which is hinged to the transmission nut and the other end of which is hinged to the fourth adsorption element.

[0039] Since the lead screw extends axially along the rotating shaft and is rotatably installed inside the rotating shaft, the transmission nut is sleeved on the lead screw and slidably set along the rotating shaft, and one end of the connecting rod is hinged to the transmission nut and the other end is hinged to the fourth adsorption component, the lead screw, transmission nut and connecting rod can make full use of the space inside the rotating shaft, thereby making the structure of the entire first drive assembly more compact and more suitable for small space scenarios.

[0040] Optionally, the lead screw includes a first section and a second section connected to each other, wherein the thread direction of the first section is opposite to that of the thread direction of the second section;

[0041] The transmission nut includes a first transmission nut and a second transmission nut, wherein the first transmission nut is sleeved on the first segment and the second transmission nut is sleeved on the second segment;

[0042] The connecting rod includes a first connecting rod and a second connecting rod. One end of the first connecting rod is hinged to the first transmission nut and the other end is hinged to the fourth adsorption member. One end of the second connecting rod is hinged to the second transmission nut and the other end is hinged to the fourth adsorption member.

[0043] Because the thread direction of the first section is opposite to that of the second section, the first transmission nut is fitted onto the first section, and the second transmission nut is fitted onto the second section. One end of the first connecting rod is hinged to the first transmission nut, and the other end is hinged to the fourth adsorption component. One end of the second connecting rod is hinged to the second transmission nut, and the other end is hinged to the fourth adsorption component. Therefore, when the screw starts to rotate, the first transmission nut and the second transmission nut can simultaneously move closer or further away along the extension direction of the screw. This allows the first and second connecting rods to simultaneously push the fourth adsorption component to slide along the first radial direction of the rotation axis. On the one hand, this allows the fourth adsorption component to slide faster along the first radial direction of the rotation axis. On the other hand, the combined support of the first and second connecting rods makes the fourth adsorption component slide more smoothly along the first radial direction of the rotation axis.

[0044] Optionally, the fourth adsorption element is a flexible adsorption element.

[0045] When the fourth adsorption element is a flexible adsorption element, as the fourth adsorption element moves toward the direction of the working material roll, when the tape comes into contact with the working material roll, even if the working material roll has a certain thickness, as the fourth adsorption element continues to move toward the working material roll, the fourth adsorption element can undergo flexible deformation, thereby allowing the tape to also come into contact with the material cylinder, thus achieving the purpose of adhering and receiving the working material roll onto the material cylinder.

[0046] Optionally, the roll changing device further includes:

[0047] A tape preparation assembly is used to provide tape to at least two of the adsorption surfaces respectively.

[0048] Since the adhesive preparation assembly can provide adhesive tape to at least two adsorption surfaces, that is, it can provide adhesive tape to the adsorption surfaces of the first adsorption element, the second adsorption element, the fourth adsorption element, and the third adsorption element, the adhesive preparation assembly automatically prepares adhesive on the adsorption surfaces of the first adsorption element, the second adsorption element, the fourth adsorption element, and the third adsorption element respectively. Therefore, it is not necessary to manually prepare adhesive on the adsorption surfaces and the third adsorption element separately, resulting in a higher degree of automation.

[0049] Optionally, the cutting and adsorption mechanism includes:

[0050] The first roll-changing adsorption assembly includes a first driving member and a fifth adsorption member. The fifth adsorption member is disposed on the first driving member. A first roll-changing adsorption surface and a second roll-changing adsorption surface are formed on the fifth adsorption member. An avoidance gap is formed between the first roll-changing adsorption surface and the second roll-changing adsorption surface.

[0051] The second roll-changing adsorption assembly includes a second driving member and a sixth adsorption member. The sixth adsorption member is disposed on the second driving member. A third roll-changing adsorption surface and a fourth roll-changing adsorption surface are formed on the sixth adsorption member. The first roll-changing adsorption surface and the third roll-changing adsorption surface are opposite to each other along a first direction. The second roll-changing adsorption surface and the fourth roll-changing adsorption surface are opposite to each other along the first direction.

[0052] A cutting assembly, comprising a third driving member and a cutter, the cutter being connected to the third driving member, and a through slit being formed between the third roll-changing adsorption surface and the fourth roll-changing adsorption surface, penetrating the sixth adsorption member along the first direction.

[0053] Optionally, the first driving member is used to drive the fifth adsorption member to move closer to or away from the sixth adsorption member along the first direction, the second driving member is used to drive the sixth adsorption member to move closer to or away from the fifth adsorption member along the first direction, and the third driving member is used to drive the cutter to pass through the through-slit to the avoidance slit along the first direction.

[0054] By creating a clearance gap between the first and second roll-changing adsorption surfaces, on the one hand, the cutter can be prevented from directly colliding with the fifth adsorption element, which could damage the fifth adsorption element or the cutter. On the other hand, the clearance gap also facilitates the cutter's passage through the material strip, thus ensuring a smoother cutting of the material strip.

[0055] By forming a through-slit between the third and fourth roll-changing adsorption surfaces, penetrating the sixth adsorption member along the first direction, and causing the third drive member to drive the cutter through the through-slit to the clearance slot along the first direction, the through-slit guides the cutter, resulting in higher cutting accuracy. Furthermore, when the cutter is located within the through-slit, the sixth adsorption member protects the cutter from external damage, thus mitigating the risk of the cutter scratching the user.

[0056] Optionally, the unwinding mechanism is used to convey the strip in the working roll downstream through the cutting and adsorption mechanism, and to carry spare rolls;

[0057] The cutting and adsorption mechanism is used to cut the strip of the passing work roll and adsorb the downstream cut end of the strip. The motion mechanism is used to drive one of the at least two adsorption surfaces to move toward the spare roll to adsorb the starting end of the spare roll. The motion mechanism is also used to drive the adsorption surface to pull the starting end to the cutting and adsorption mechanism. The cutting and adsorption mechanism is also used to adsorb the starting end.

[0058] Optionally, the first rotary drive is further configured to drive the adsorption assembly to rotate around the first axis so that another of the at least two adsorption surfaces faces the cutting adsorption mechanism, and the motion mechanism is further configured to drive the other adsorption surface to move closer to the cutting adsorption mechanism so as to adhere the tape on the other adsorption surface to the starting end and the downstream cut end.

[0059] Secondly, this application discloses a battery cell winding device, including the winding device described in any of the first aspects above.

[0060] Because the winding device has a simple structure and low cost, when the battery cell winding equipment includes a winding device, the structure of the battery cell winding equipment can be simplified and the cost can be reduced.

[0061] Compared with the prior art, the beneficial effects of this application are as follows:

[0062] In this application, a first rotary drive unit drives the adsorption assembly to rotate around a first axis, so that one of the at least two adsorption surfaces faces the starting end of the spare material roll. Then, a motion mechanism drives this adsorption surface to pull the starting end of the spare material roll to the cutting adsorption mechanism, thus realizing the function of unwinding the spare material roll. Furthermore, the first rotary drive unit drives the adsorption assembly to continue rotating around the first axis, so that the other adsorption surface of the at least two adsorption surfaces faces the starting end of the spare material roll. Then, a motion mechanism drives this adsorption surface to move closer to the starting end of the spare material roll, so that the starting end of the spare material roll and the material roll of the working material roll are spliced ​​together by the adhesive tape on the adsorption surface, thus realizing the function of splicing tape. That is, each of the at least two adsorption surfaces of the same adsorption assembly can perform different functions. In other words, the same adsorption assembly integrates at least two functions, thus simplifying the structure of the roll-changing device to a certain extent and reducing its cost.

[0086] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

These terms are primarily for the purpose of better describing this application and its embodiments, and are not intended to limit the indicated device, element, or component to having a specific orientation, or to be constructed and operated in a specific orientation.

[0088] Furthermore, in addition to indicating location or positional relationship, some of the aforementioned terms may also have other meanings. For example, the term "above" may also be used in some cases to indicate a certain dependency or connection relationship. Those skilled in the art can understand the specific meaning of these terms in this application based on the specific circumstances.

Unless otherwise stated, "at least two" means two or more.

[0091] Before explaining the technical solution of this application, the background technology of this application shall be explained first.

[0092] In the process of manufacturing battery cells using winding needles, battery cell winding equipment typically incorporates a winding changer to improve production efficiency and prevent downtime. This changer holds a spare roll and a working roll. Once the working roll is unwound, the changer allows the spare roll to take over, ensuring continuous equipment operation and improving production efficiency. However, the complex structure of these changing devices in related technologies leads to high costs. Therefore, this application provides a winding changer and a battery cell winding machine to address these issues.

[0093] The technical solution of this application will be described below with reference to specific embodiments and accompanying drawings.

[0094] Figure 1 This is a schematic diagram of the structure of a strapping mechanism 100 provided in one embodiment of this application. Figure 2 yes Figure 1 The schematic diagram of the connecting mechanism 100 without omitting the motion mechanism 1 is as follows: Figure 3A yes Figure 2 A schematic diagram of the connecting mechanism 100 from another perspective. Figure 4 yes Figure 1 The schematic diagram of the tape-connecting mechanism 100 applied to the roll-changing device 200.

[0095] See Figure 1 , Figure 2 and Figure 3AThe roll changing device 200 includes an unwinding mechanism 201, a cutting and adsorption mechanism 202, and a tape receiving mechanism 100. The cutting and adsorption mechanism 202 is located downstream of the unwinding mechanism 201. The tape receiving mechanism 100 includes a motion mechanism 1, a mounting base 2, an adsorption assembly 3, and a first rotary drive 4. The mounting base 2 is disposed on the motion mechanism 1. The adsorption assembly 3 is rotatably mounted on the mounting base 2 around a first axis O. At least two adsorption surfaces 31 are formed on the adsorption assembly 3, and the at least two adsorption surfaces 31 can independently adsorb. The at least two adsorption surfaces 31 have different orientations. The first rotary drive 4 is disposed on the mounting base 2 and connected to the adsorption assembly 3.

[0096] The motion mechanism 1 is used to drive the mounting base 2 to move, thereby driving the adsorption assembly 3 to move between the cutting adsorption mechanism 202 and the unwinding mechanism 201. The first rotary drive 4 is used to drive the adsorption assembly 3 to rotate around the first axis O, thereby changing the orientation of the adsorption surface 31.

[0097] In this embodiment, since the mounting base 2 is disposed on the motion mechanism 1, and the adsorption component 3 is rotatably mounted on the mounting base 2 around the first axis O, when the motion mechanism 1 drives the mounting base 2 to move, it can drive the adsorption component 3 to move between the cutting adsorption mechanism 202 and the unwinding mechanism 201. Since the adsorption component 3 is rotatably mounted on the mounting base 2 around the first axis O, and the first rotary drive 4 is disposed on the mounting base 2 and connected to the adsorption component 3, the first rotary drive 4 can drive the adsorption component 3 to rotate around the first axis O.

[0098] Since at least two adsorption surfaces 31 are formed on the adsorption component 3, and the orientations of the at least two adsorption surfaces 31 are different, the orientation of the adsorption surfaces 31 can be changed when the adsorption component 3 rotates around the first axis O.

[0099] Based on this, see Figure 4 , Figure 4 yes Figure 1 The diagram shows the structure of the tape-connecting mechanism 100 when applied to the roll-changing device 200. When the tape-connecting mechanism 100 is applied to the roll-changing device 200, the unwinding mechanism 201 can be used to convey the tape E in the working roll A downstream via the cutting and adsorption mechanism 202, and to carry the spare roll. Specifically, the unwinding mechanism 201 may include a first unwinding shaft 2011 and a second unwinding shaft 2012. The first unwinding shaft 2011 can carry the working roll A and convey the tape E in the working roll A downstream via the cutting and adsorption mechanism 202, while the second unwinding shaft 2012 can carry the spare roll B.

[0100] In this way, when the strip in the working material roll A is about to be unwound and the spare material roll B needs to take over the unwinding of the working material roll A, firstly, the cutting and adsorption mechanism 202 can cut off the strip E of the working material roll A and adsorb the downstream cut end of the strip E. Then, the first rotary drive 4 can drive the adsorption assembly 3 to rotate around the first axis O, so that one of the at least two adsorption surfaces 31 faces the starting end of the spare material roll B. Next, the motion mechanism 1 can drive the adsorption surface 31 to move closer to the spare material roll B to adsorb the starting end of the spare material roll B. The motion mechanism 1 is also used to drive the adsorption surface 31 to pull the starting end of the spare material roll B to the cutting and adsorption mechanism 202. When the starting end of the spare material roll B is pulled to the cutting and adsorption mechanism 202, the cutting and adsorption mechanism 202 can adsorb the starting end of the spare material roll B.

[0101] Next, the first rotary drive 4 can drive the adsorption assembly 3 to rotate again around the first axis O, so that another adsorption surface 31 of the at least two adsorption surfaces 31 faces the cutting adsorption mechanism 202. Finally, the motion mechanism 1 can drive the adsorption surface 31 to move closer to the cutting adsorption mechanism 202, so as to adhere the tape C on the adsorption surface 31 to the starting end and the downstream cut end of the spare material roll B located at the cutting adsorption mechanism 202, thereby splicing the starting end of the spare material roll B and the material strip of the working material roll A through the tape C, so as to achieve the purpose of continuing to unwind by replacing the working material roll A with the spare material roll B.

[0102] As can be seen, by driving the adsorption assembly 3 to rotate around the first axis O via the first rotary drive 4, one of the at least two adsorption surfaces 31 faces the starting end of the spare material roll B. Then, the motion mechanism 1 drives the adsorption surface 31 to pull the starting end of the spare material roll B to the cutting adsorption mechanism 202, thus realizing the function of unwinding the spare material roll B. In addition, by driving the adsorption assembly 3 to continue rotating around the first axis O via the first rotary drive 4, the other adsorption surface 31 faces the starting end of the spare material roll B. Then, the motion mechanism 1 drives the adsorption surface 31 to move closer to the starting end of the spare material roll B, so that the starting end of the spare material roll B and the downstream cut end of the working material roll A are spliced ​​together by the adhesive tape C on the adsorption surface 31, thus realizing the function of tape splicing. That is, each of the at least two adsorption surfaces 31 of the same adsorption component 3 can perform different functions. In other words, the same adsorption component 3 integrates at least two functions. Therefore, the structure of the roll changing device 200 can be simplified to a certain extent, and the cost of the roll changing device 200 can be reduced.

[0103] In some embodiments, see Figure 3A and Figure 5 , Figure 5 yes Figure 3AThe attached conveyor mechanism 100 is shown in a structural schematic diagram from another perspective. The adsorption assembly 3 includes a rotating shaft 32 and at least two adsorption elements 33. The rotating shaft 32 is rotatably mounted on the mounting base 2 around the first axis O. The first rotation drive 4 is connected to the rotating shaft 32. At least two adsorption elements 33 are disposed on the rotating shaft 32. At least two adsorption surfaces 31 correspond one-to-one with at least two adsorption elements 33. Each adsorption element 33 has an adsorption surface 31 formed on it.

[0104] Since the rotating shaft 32 is rotatably mounted on the mounting base 2 around the first axis O, and the first rotating drive 4 is connected to the rotating shaft 32, the first rotating drive 4 can drive the rotating shaft 32 to rotate around the first axis O.

[0105] When the rotating shaft 32 rotates around the first axis O, since at least two adsorption elements 33 are disposed on the rotating shaft 32, the at least two adsorption elements 33 can be driven to rotate around the first axis O. When the at least two adsorption elements 33 rotate around the first axis O, since at least two adsorption surfaces 31 correspond one-to-one with the at least two adsorption elements 33, and each adsorption surface 31 is formed on the corresponding adsorption element 33, the at least two adsorption surfaces 31 can be driven to rotate around the first axis O, thereby achieving the purpose of adjusting the orientation of the adsorption surfaces 31.

[0106] Since at least two adsorption surfaces 31 correspond one-to-one with at least two adsorption elements 33, and each adsorption surface 31 is formed on the corresponding adsorption element 33, the at least two adsorption surfaces 31 can be made independent, thereby avoiding the situation where the at least two adsorption surfaces 31 affect each other.

[0107] The aforementioned adsorption element 33 can be a plate-like structure or other shapes, and this embodiment does not limit it.

[0108] The aforementioned adsorption surface 31 can be formed by at least two adsorption holes provided on the adsorption member 33. Of course, the adsorption surface 31 can also be formed in other ways, as long as it can play an adsorption role. This embodiment does not limit this.

[0109] In some embodiments, see Figure 3A and Figure 5 The adsorption component 3 includes a rotating shaft 32, which is rotatably mounted on the mounting base 2 around a first axis O. A first rotation drive 4 is connected to the rotating shaft 32, and at least two adsorption surfaces 31 are provided on the rotating shaft 32.

[0110] When the rotating shaft 32 is provided with at least two adsorption surfaces 31, the adsorption surfaces 31 can be directly formed on the rotating shaft 32. In this way, there is no need to provide additional parts to form the adsorption surfaces 31, thereby simplifying the structure of the adsorption assembly 3 and reducing the cost of the adsorption assembly 3.

[0111] There are multiple ways to implement the first rotary drive component 4 described above. In one possible implementation, see [link to relevant documentation]. Figure 3A The first rotary drive component 4 may include a motor, a drive pulley, a timing belt, and a driven pulley. The driven pulley is sleeved on the rotary shaft 32, the drive pulley is connected to the output shaft of the motor, and the timing belt is sleeved on the drive pulley and the driven pulley. In this way, when the output shaft of the motor starts to rotate, it can drive the drive pulley to rotate, and then drive the driven pulley to rotate through the timing belt. When the driven pulley starts to rotate, it can achieve the purpose of driving the rotary shaft 32 to rotate around the first axis O.

[0112] Of course, in other embodiments, the first rotary drive 4 may also be other possible structures, as long as it can achieve the purpose of driving the rotary shaft 32 to rotate around the first axis O. This embodiment does not limit the first rotary drive 4.

[0113] In some embodiments, see Figure 3A and Figure 5 At least two adsorption elements 33 are distributed around the first axis O, and each adsorption surface 31 is arranged radially toward the rotation axis 32. The adsorption surface 31 is located on the side of the corresponding adsorption element 33 away from the first axis O.

[0114] By positioning the adsorption surface 31 on the side of the corresponding adsorption element 33 away from the first axis O, the adsorption surface 31 can be positioned on the outside of the adsorption element 33. This avoids interference between the adsorption element 33 and the adsorption operation of the adsorption surface 31, allowing the adsorption surface 31 to adsorb more firmly and stably.

[0115] In addition, by distributing at least two adsorption elements 33 around the first axis O, the adsorption surfaces 31 on at least two adsorption elements 33 can rotate around the first axis O during the rotation of the rotating shaft 32 around the first axis O, thereby allowing for very flexible adjustment of the orientation of the adsorption surfaces 31.

[0116] In some embodiments, see Figure 2 , Figure 3A and Figure 3B , Figure 3B yes Figure 3A A schematic diagram of a portion of the intermediate belt mechanism 100 from another perspective shows at least two adsorption elements 33, including a first adsorption element 332, a second adsorption element 333, a third adsorption element 334, and a fourth adsorption element 331. The first adsorption element 332 and the second adsorption element 333 are arranged adjacent to each other circumferentially along the rotation axis 32, and the fourth adsorption element 331 and the third adsorption element 334 are arranged adjacent to each other circumferentially along the rotation axis 32. The first adsorption element 332 and the fourth adsorption element 331 are arranged along the first radial direction of the rotation axis 32. Figure 2The second adsorption member 333 and the third adsorption member 334 are arranged relative to each other along the second radial direction of the rotation axis 32 (in the X-axis direction). Figure 2 The first radial direction and the second radial direction are set relative to each other (in the Z-axis direction).

[0117] Because the first adsorption element 332 and the fourth adsorption element 331 are along the first radial direction of the rotation axis 32 ( Figure 2 The second adsorption member 333 and the third adsorption member 334 are arranged relative to each other along the second radial direction of the rotation axis 32 (in the X-axis direction). Figure 2 The two adsorbents are arranged relative to each other in the Z-axis direction. The first radial direction and the second radial direction are perpendicular to each other. Therefore, every 90° rotation of the rotating shaft 32 around the first axis O can change the orientation of the adsorption surface 31 of the first adsorbent 332, the adsorption surface 31 of the second adsorbent 333, the adsorption surface 31 of the fourth adsorbent 331, and the adsorption surface 31 of the third adsorbent 334 by 90° respectively. On the one hand, it can make at least two adsorbents 33 more regularly distributed, which is convenient for processing. On the other hand, it can also make motion control simpler.

[0118] See Figure 3B and Figure 4 The first rotary drive 4 is used to drive the adsorption assembly 3 to rotate around the first axis O, so that the adsorption surface 31 of the first adsorption member 332 faces the spare material roll B and the adsorption surface 31 of the second adsorption member 333 faces the cutting adsorption mechanism 202 respectively.

[0119] When the adsorption surface 31 of the first adsorption member 332 faces the spare material roll B, it is convenient to pick up the starting end of the spare material roll B at the spare material roll B through the adsorption surface 31 of the first adsorption member 332 and pull the starting end to the cutting adsorption mechanism 202. When the adsorption surface 31 of the second adsorption member 333 faces the cutting adsorption mechanism 202, it is convenient to adhere the tape C on the adsorption surface 31 of the second adsorption member 333 to the starting end of the spare material roll B and the material strip of the working material roll A located at the cutting adsorption mechanism 202.

[0120] Considering that the first adsorption element 332 is mainly used to adsorb the starting end of the spare material roll B, requiring strong suction, while the second adsorption element 333, the third adsorption element 334, and the fourth adsorption element 331 are mainly used to adsorb the tape C, and the adsorption force can be smaller, based on this, see... Figure 3B The first adsorption element 332 can be adsorbed by a suction cup, and the second adsorption element 333, the third adsorption element 334 and the fourth adsorption element 331 can be adsorbed by adsorption holes. In this way, the cost can be reduced as much as possible while meeting the functional requirements.

[0121] In some embodiments, see Figure 2 and Figure 3AThe attaching mechanism 100 further includes a first driving assembly 5, which is connected to a fourth adsorption member 331 among at least two adsorption members 33. The first driving assembly 5 is used to drive the fourth adsorption member 331 to slide. Specifically, the first driving assembly 5 can drive the fourth adsorption member 331 along a first radial direction of the rotation axis 32. Figure 2 (In the X-axis direction) reciprocating sliding.

[0122] Since the first driving assembly 5 is connected to the fourth adsorption member 331 of at least two adsorption members 33, the first driving assembly 5 can drive the fourth adsorption member 331 along the first radial direction of the rotation axis 32. Figure 2 It slides back and forth along the X-axis. In this way, when tape C is adsorbed on the adsorption surface 31 of the fourth adsorption element 331, see... Figure 4 and Figure 6 , Figure 6 This is a schematic diagram of the structure when tape C is adhered to the work roll A. When it is necessary to adhere tape C on the adsorption surface 31 of the fourth adsorption member 331 to the work roll A, so that the remaining tape in the work roll A can be adhered to the material cylinder D for storage, firstly, the first rotary drive member 4 can drive the rotary shaft 32 to rotate around the first axis O, so that the adsorption surface 31 of the fourth adsorption member 331 faces the work roll A. Then, the motion mechanism 1 can drive the fourth adsorption member 331 to move towards the work roll A. At the same time, the first drive assembly 5 can drive the fourth adsorption member 331 along the first radial direction of the rotary shaft 32 ( Figure 2 Slide the tape C on the adsorption surface 31 of the fourth adsorption element 331 towards the working material roll A in the X-axis direction. In this way, the tape C on the adsorption surface 31 of the fourth adsorption element 331 can be adhered to the working material roll A and the material cylinder D. This allows the remaining tape in the working material roll A to be adhered to the material cylinder D for storage.

[0123] It can be seen that when the tape receiving mechanism 100 also includes the first driving component 5, in addition to driving the fourth adsorption member 331 to move towards the working material roll A through the motion mechanism 1, the first driving component 5 can also drive the fourth adsorption member 331 along the first radial direction of the rotation axis 32. Figure 2 The fourth adsorption member 331 slides towards the working material roll A in the X-axis direction. Therefore, on the one hand, it can improve the efficiency of the fourth adsorption member 331 moving towards the working material roll A. On the other hand, it can also make the rotating shaft 32 farther away from the first unwinding shaft 2011 along the first radial direction, thereby avoiding interference between the rotating shaft 32 and the first unwinding shaft 2011 or other components in the winding device 200.

[0124] The first drive component 5 can be implemented in various ways. In one possible implementation, the first drive component 5 can be a cylinder. Of course, the first drive component 5 can also be other possible structures. For example, in another possible implementation, see [link to relevant documentation]. Figure 5 and Figure 7 , Figure 7 yes Figure 5 The schematic diagram of the connecting mechanism 100, omitting the fourth adsorption element 331, shows that the first driving assembly 5 includes a lead screw 51, a second rotary driving element 52, a transmission nut 53, and a connecting rod 54. The lead screw 51 is located along the axial direction of the rotation shaft 32. Figure 5 The first rotating member 52 is rotatably mounted within the rotating shaft 32 (extending in the Y-axis direction). The second rotating drive member 52 is disposed on the mounting base 2 and connected to the lead screw 51. The transmission nut 53 is sleeved on the lead screw 51 and slidably disposed along the axial direction of the rotating shaft 32. The fourth adsorption member 331 is slidably disposed. Specifically, the fourth adsorption member 331 can be slidably disposed along the first radial direction of the rotating shaft 32 (…). Figure 5 The connecting rod 54 is slidably set in the X-axis direction, with one end hinged to the transmission nut 53 and the other end hinged to the fourth adsorption member 331.

[0125] Because the lead screw 51 is along the axial direction of the rotation axis 32 ( Figure 5 The second rotary drive 52 is rotatably mounted in the rotating shaft 32 (extending in the Y-axis direction). The second rotary drive 52 is disposed in the mounting base 2 and connected to the lead screw 51. Therefore, the second rotary drive 52 can drive the lead screw 51 to rotate.

[0126] When the lead screw 51 starts to rotate, since the transmission nut 53 is sleeved on the lead screw 51 and slidably disposed along the axial direction of the rotation shaft 32, the lead screw 51 can drive the transmission nut 53 to slide along the axial direction of the rotation shaft 32 when it starts to rotate. Since one end of the connecting rod 54 is hinged to the transmission nut 53 and the other end is hinged to the fourth adsorption member 331, and since the fourth adsorption member 331 is along the first radial direction of the rotation shaft 32 (… Figure 5 The drive nut 53 is slidably positioned along the X-axis direction, so when the drive nut 53 slides along the axial direction of the rotating shaft 32, the connecting rod 54 can drive the fourth adsorption member 331 along the first radial direction of the rotating shaft 32. Figure 5 Sliding along the X-axis can thus drive the fourth adsorption element 331 along the first radial direction of the rotation axis 32. Figure 2 The purpose is to slide the material roll A closer to the workpiece in the X-axis direction.

[0127] Among them, due to the axial direction of the lead screw 51 along the rotation axis 32 ( Figure 5The screw 51 extends along the Y-axis and is rotatably mounted inside the rotating shaft 32. The transmission nut 53 is sleeved on the lead screw 51 and slidably arranged along the axial direction of the rotating shaft 32. One end of the connecting rod 54 is hinged to the transmission nut 53 and the other end is hinged to the fourth adsorption member 331. Therefore, the lead screw 51, transmission nut 53 and connecting rod 54 can make full use of the space inside the rotating shaft 32, so that the structure of the entire first drive assembly 5 is more compact and more suitable for small space scenarios.

[0128] There are several ways in which the second rotary drive 52 is connected to the lead screw 51. In one possible implementation, see [link to relevant documentation]. Figure 5 A drive wheel can be fitted onto the output shaft of the second rotary drive 52, and a driven wheel can be fitted onto the lead screw 51. A synchronous belt is fitted onto the drive wheel and the driven wheel. In this way, when the output shaft of the second rotary drive 52 starts to rotate, it can drive the drive wheel to rotate. When the drive wheel starts to rotate, it can drive the driven wheel to rotate through the synchronous belt, thereby achieving the purpose of driving the lead screw 51 to rotate.

[0129] In some embodiments, see Figure 7 The lead screw 51 includes a first section 511 and a second section 512 connected to each other. The thread direction of the first section 511 is opposite to that of the thread direction of the second section 512.

[0130] The transmission nut 53 includes a first transmission nut 531 and a second transmission nut 532. The first transmission nut 531 is sleeved on the first segment 511, and the second transmission nut 532 is sleeved on the second segment 512.

[0131] The connecting rod 54 includes a first connecting rod 541 and a second connecting rod 542. One end of the first connecting rod 541 is hinged to the first transmission nut 531 and the other end is hinged to the fourth adsorption member 331. One end of the second connecting rod 542 is hinged to the second transmission nut 532 and the other end is hinged to the fourth adsorption member 331.

[0132] Since the thread direction of the first segment 511 is opposite to that of the second segment 512, the first transmission nut 531 is fitted onto the first segment 511, and the second transmission nut 532 is fitted onto the second segment 512. One end of the first connecting rod 541 is hinged to the first transmission nut 531, and the other end is hinged to the fourth suction member 331. One end of the second connecting rod 542 is hinged to the second transmission nut 532, and the other end is hinged to the fourth suction member 331. Therefore, when the lead screw 51 starts to rotate, the first transmission nut 531 and the second transmission nut 532 can be connected. The two transmission nuts 532 move closer or further away from each other along the extension direction of the lead screw 51, thereby enabling the first connecting rod 541 and the second connecting rod 542 to simultaneously push the fourth adsorption member 331 to slide along the first radial direction of the rotating shaft 32. On the one hand, this allows the fourth adsorption member 331 to slide faster along the first radial direction of the rotating shaft 32. On the other hand, the combined support of the first connecting rod 541 and the second connecting rod 542 makes the fourth adsorption member 331 slide more smoothly along the first radial direction of the rotating shaft 32.

[0133] The second rotary drive component 52 can be a motor or any other possible structure, as long as it can drive the lead screw 51 to rotate. This embodiment does not limit this.

[0134] See Figure 4 and Figure 6 Considering that when the tape C is bonded to the working material roll A and the material cylinder D via the adsorption surface 31 on the fourth adsorption member 331, the working material roll A has a certain thickness, which causes the tape C to be unable to abut against the material cylinder D under the support of the working material roll A. Consequently, the tape C cannot be simultaneously bonded to both the working material roll A and the material cylinder D, making it impossible for the working material roll A to be stored in the material cylinder D. To avoid this situation, in some embodiments, see... Figure 5 The fourth adsorption element 331 is a flexible adsorption element.

[0135] When the fourth adsorption member 331 is a flexible adsorption member, as the fourth adsorption member 331 moves toward the direction of the working material roll A, when the tape C comes into contact with the working material roll A, even if the working material roll A has a certain thickness, as the fourth adsorption member 331 continues to move toward the direction of the working material roll A, the fourth adsorption member 331 can undergo flexible deformation, thereby allowing the tape C to also come into contact with the material cylinder D, thus achieving the purpose of adhering and receiving the working material roll A onto the material cylinder D.

[0136] Specifically, when the fourth adsorption element 331 is a flexible adsorption element, the fourth adsorption element 331 can be a sponge or a flexible element of any other material. This embodiment does not limit this.

[0137] In some embodiments, see Figure 1 , Figure 3A and Figure 8 , Figure 8 yes Figure 1 The schematic diagram of the connecting mechanism is shown after omitting part of the motion mechanism 1. The motion mechanism 1 includes a first translation component 11, a second translation component 12 and a third translation component 13. The second translation component 12 is disposed on the first translation component 11, the third translation component 13 is disposed on the second translation component 12, and the mounting base 2 is disposed on the third translation component 13.

[0138] The first translation component 11 is used to drive the second translation component 12 along the first direction ( Figure 1 The second translation component 12 is used to drive the third translation component 13 along the second direction (X-axis direction) for translation. Figure 1 The third translation component 13 is used to drive the mounting base 2 along the third direction (Z-axis direction) for translation. Figure 1 The third direction is translated along the Y-axis, and the third direction is parallel to the first axis O, with the first direction, the second direction, and the third direction being mutually perpendicular to each other.

[0139] Because the first translation component 11 is used to drive the second translation component 12 along the first direction ( Figure 1 The second translation component 12 is used to drive the third translation component 13 along the second direction (X-axis direction) for translation. Figure 1 The third translation component 13 is used to drive the mounting base 2 along the third direction (Z-axis direction) for translation. Figure 1 The mounting base 2 is positioned on the third translation component 13. Since the third direction is parallel to the first axis O and the first direction, the second direction, and the third direction are mutually perpendicular, the mounting base 2 can have at least six degrees of freedom through the combined action of the first translation component 11, the second translation component 12, and the third translation component 13. This allows for very flexible movement of the adsorption component 3 between at least two workstations.

[0140] The first translation component 11 may include a motor and a lead screw and nut mechanism. The lead screw of the lead screw and nut mechanism extends along the first direction. The motor is connected to the lead screw of the lead screw and nut mechanism. The second translation component 12 is disposed on the nut of the lead screw and nut mechanism. In this way, by driving the lead screw to rotate by the motor, the purpose of driving the second translation component 12 to translate along the first direction can be achieved.

[0141] Of course, the first translation component 11 described above can also have other possible structures, as long as it can achieve the purpose of driving the second translation component 12 to translate along the first direction. This embodiment does not limit this.

[0142] The structures of the second translation component 12 and the third translation component 13 can be the same as those of the first translation component 11. For details, please refer to the description of the first translation component 11 in the above embodiments. This embodiment will not repeat the description here.

[0143] One embodiment of this application also provides a roll changing device 200, see [link to previous document]. Figure 4 The roll changing device 200 includes a tape receiving mechanism 100.

[0144] The structure of the tape-connecting mechanism 100 can be the same as that of any of the tape-connecting mechanisms 100 described in the above embodiments, and can bring the same or similar beneficial effects. For details, please refer to the description of the tape-connecting mechanism 100 in the above embodiments. This embodiment will not repeat the description here.

[0145] In this embodiment, since each adsorption surface 31 of the at least two adsorption surfaces 31 of the same adsorption component 3 can perform different functions, in other words, the same adsorption component 3 integrates at least two functions. Therefore, the structure of the roll changing device 200 can be simplified to a certain extent, and the cost of the roll changing device 200 can be reduced.

[0146] In some embodiments, see Figure 3A and Figure 4 The rewinding device 200 also includes an unwinding mechanism 201 and a cutting and adsorption mechanism 202. The unwinding mechanism 201 includes a first unwinding shaft 2011 and a second unwinding shaft 2012. The first unwinding shaft 2011 is used to carry one of the working roll A and the spare roll B. Figure 4 The middle unwinding shaft 2012 is used to carry the other one of the working coil A and the spare coil B. Figure 4 (Middle-load spare material roll B).

[0147] The adsorption component 3 includes at least two adsorption elements 33, both of which are disposed on the rotating shaft 32. At least two adsorption surfaces 31 correspond one-to-one with the at least two adsorption elements 33. Each adsorption element 33 has an adsorption surface 31 formed on it. The at least two adsorption elements 33 include a first adsorption element 332, a second adsorption element 333, a fourth adsorption element 331, and a third adsorption element 334.

[0148] The first rotary drive 4 is used to drive the adsorption assembly 3 to rotate around the first axis O, so that the first adsorption member 332 faces the starting end of the spare roll B, the second adsorption member 333 and the third adsorption member 334 face the cutting adsorption mechanism 202, and the fourth adsorption member 331 faces the working roll A.

[0149] The motion mechanism 1 is used to drive the adsorption assembly 3 to move between the starting end of the spare material roll B, the cutting adsorption mechanism 202, and the working material roll A.

[0150] In this embodiment, when the strip in working roll A is almost unwound and it is necessary for spare roll B to take over from working roll A to continue unwinding, thus completing the roll change function, see [reference needed]. Figure 4 and Figure 9 , Figure 9 This is a schematic diagram of a roll-changing process provided in an embodiment of this application. First, the cutting and adsorption mechanism 202 can cut the strip E of the working roll A and adsorb the strip E located downstream of the cutting and adsorption mechanism 202. Figure 9 In state a), the first rotary drive 4 can drive the adsorption assembly 3 to rotate around the first axis O (if the adsorption surface 31 of the first adsorption member 332 faces the starting end of the spare material roll B in the initial state, then no rotation is required), so that the adsorption surface 31 of the first adsorption member 332 faces the starting end of the spare material roll B. The first adsorption member 332 is used to adsorb the starting end of the spare material roll B. Then, when the motion mechanism 1 drives the adsorption assembly 3 to move between the starting end of the spare material roll B and the cutting adsorption mechanism 202, the starting end of the spare material roll B can be pulled to the cutting adsorption mechanism 202 through the first adsorption member 332. Figure 9 In state b), the cutting and adsorption mechanism 202 is used to adsorb the starting end of the spare material roll B.

[0151] Then, the first rotary drive 4 can drive the first axis O of the adsorption assembly 3 to rotate, so that the adsorption surface 31 of the second adsorption member 333 faces the starting end of the spare material roll B and the material strip E of the working material roll A. Then, the motion mechanism 1 can drive the adsorption assembly 3 to move, so as to bond the adhesive tape C on the adsorption surface 31 of the second adsorption member 333 to the starting end of the spare material roll B and the material strip of the working material roll A, so that the starting end of the spare material roll B and the material strip of the working material roll A are bonded together by the adhesive tape C to achieve the function of tape splicing. Figure 9 (middle c state).

[0152] Next, the motion mechanism 1 can drive the adsorption component 3 to move, so that the adsorption component 3 moves to the other side of the material belt E along the thickness direction of the material belt E. Figure 9 (Left side of the middle material belt E), the adsorption surface 31 of the third adsorption element 334 faces the cutting adsorption mechanism 202 ( Figure 9 In the middle d state), the motion mechanism 1 can drive the adsorption component 3 to move, so as to stick the tape C on the third adsorption component 334 to the starting end of the spare material roll B and the material strip E of the working material roll A. At this point, the tape C can be stuck to both sides of the material strip E along the thickness direction. Figure 9 (middle e state).

[0153] Finally, with the adsorption surface 31 of the fourth adsorption member 331 facing the work roll A, the motion mechanism 1 can drive the adsorption assembly 3 to move closer to the work roll A, so as to adhere the tape C on the adsorption surface 31 of the fourth adsorption member 331 to the remaining tape E of the work roll A, thereby achieving the purpose of adhering the remaining tape E in the work roll A to the material cylinder D for storage. Figure 9 (middle f state).

[0154] As can be seen, when the first rotary drive 4 can drive the first axis O of the adsorption assembly 3 to rotate, and the motion mechanism 1 can drive the adsorption assembly 3 to move between the starting end of the spare material roll B, the cutting adsorption mechanism 202 and the working material roll A, in addition to realizing the function of connecting the tape, it can also realize the function of adhering the remaining material tape E in the working material roll A to the material cylinder D for storage, making the function more diversified.

[0155] In some embodiments, see Figure 4 The roll changing device 200 also includes a glue preparation assembly 203, which is used to provide adhesive tape C to the at least two adsorption surfaces respectively. Specifically, adhesive tape C can be provided to the adsorption surface 31 of the first adsorption member 332, the adsorption surface 31 of the second adsorption member 333, the adsorption surface 31 of the fourth adsorption member 331, and the adsorption surface 31 of the third adsorption member 334 respectively.

[0156] Since the adhesive preparation assembly 203 can provide adhesive tape C to at least two adsorption surfaces 31, that is, it can provide adhesive tape C to the adsorption surfaces 31 of the first adsorption member 332, the second adsorption member 333, the fourth adsorption member 331, and the third adsorption member 334, the adhesive preparation assembly 203 automatically prepares adhesive on the adsorption surfaces 31 of the first adsorption member 332, the second adsorption member 333, the fourth adsorption member 331, and the third adsorption member 334 respectively. Therefore, there is no need to manually prepare adhesive on the adsorption surfaces 31 and the third adsorption member 334 respectively, resulting in a higher degree of automation.

[0157] The adhesive preparation assembly 203 can be a robotic arm or any structure capable of preparing adhesive on the adsorption surface 31 of the first adsorption member 332, the adsorption surface 31 of the second adsorption member 333, the adsorption surface 31 of the fourth adsorption member 331, and the adsorption surface 31 of the third adsorption member 334. This embodiment does not limit this.

[0158] In some embodiments, see Figure 4 and Figure 10 , Figure 10 yes Figure 4A schematic diagram of the structure of the second roll-changing adsorption assembly 2022 is shown. The cutting adsorption mechanism 202 includes a first roll-changing adsorption assembly 2021, a second roll-changing adsorption assembly 2022, and a cutting assembly 2023. The first roll-changing adsorption assembly 2021 includes a first driving member 20211 and a fifth adsorption member 20212. The fifth adsorption member 20212 is disposed on the first driving member 20211. The fifth adsorption member 20212 has a first roll-changing adsorption surface 20212a and a second roll-changing adsorption surface 20212b that can be independently adsorbed. An avoidance slit 20212c is formed between the first roll-changing adsorption surface 20212a and the second roll-changing adsorption surface 20212b.

[0159] The second roll-changing adsorption assembly 2022 includes a second driving member 20221 and a sixth adsorption member 20222. The sixth adsorption member 20222 is disposed on the second driving member 20221. The sixth adsorption member 20222 has independently adsorption surfaces 20222a and 20222b, which are third roll-changing adsorption surfaces 20222a and 20222b respectively. The first roll-changing adsorption surface 20212a and the third roll-changing adsorption surface 20222a are along a first direction (…). Figure 4 The second roll-changing adsorption surface 20212b and the fourth roll-changing adsorption surface 20222b are opposite each other along the first direction (in the X-axis direction).

[0160] The cutting assembly 2023 includes a third driving member 20231 and a cutter 20232. The third driving member 20231 is disposed on the sixth adsorption member 20222, and the cutter 20232 is connected to the third driving member 20231. A through slit 20222c is formed between the third roll-changing adsorption surface 20222a and the fourth roll-changing adsorption surface 20222b, which penetrates the sixth adsorption member 20222 along the first direction.

[0161] The first driving member 20211 is used to drive the fifth adsorption member 20212 to move closer to or further away from the sixth adsorption member 20222 along the first direction. The second driving member 20221 is used to drive the sixth adsorption member 20222 to move closer to or further away from the fifth adsorption member 20212 along the first direction. The third driving member 20231 is used to drive the cutter 20232 to pass through the through-slit 20222c to the avoidance slit 20212c along the first direction.

[0162] In this embodiment, since the first driving member 20211 can drive the fifth adsorption member 20212 to move closer to or further away from the sixth adsorption member 20222 along the first direction, and the second driving member 20221 can drive the sixth adsorption member 20222 to move closer to or further away from the fifth adsorption member 20212 along the first direction, the material strip E can be clamped between the sixth adsorption member 20222 and the fifth adsorption member 20212.

[0163] When the tape E is clamped between the sixth adsorption member 20222 and the fifth adsorption member 20212, on the one hand, it facilitates the adsorption of tape E by the first rewind adsorption surface 20212a, the second rewind adsorption surface 20212b, the third rewind adsorption surface 20222a, and the fourth rewind adsorption surface 20222b respectively. On the other hand, the sixth adsorption member 20222 and the fifth adsorption member 20212 can also fix tape E so that the cutter 20232 can smoothly cut tape E.

[0164] By forming a clearance slit 20212c between the first roll-changing adsorption surface 20212a and the second roll-changing adsorption surface 20212b, on the one hand, it can prevent the cutter 20232 from directly colliding with the fifth adsorption element 20212, thus avoiding damage to the fifth adsorption element 20212 or the cutter 20232. On the other hand, the clearance slit 20212c also facilitates the cutter 20232 passing through the material strip E, thereby better ensuring that the material strip E can be cut smoothly.

[0165] By forming a through-slit 20222c extending through the sixth adsorption member 20222 in a first direction between the third and fourth adsorption surfaces 20222a and 20222b, and by driving the cutter 20232 through the through-slit 20222c to the clearance slit 20212c in the first direction via the third drive member 20231, the through-slit 20222c guides the cutter 20232, resulting in higher operating accuracy. Furthermore, when the cutter 20232 is located within the through-slit 20222c, the sixth adsorption member 20222 protects the cutter 20232 from scratches, thus mitigating the risk of the cutter 20232 injuring the user.

[0166] It is worth noting that, since the fifth adsorption element 20212 has a first rewind adsorption surface 20212a and a second rewind adsorption surface 20212b that can be independently adsorbed, the first rewind adsorption surface 20212a can be used to adsorb the material strip E, and the second rewind adsorption surface 20212b can be used to adsorb the starting end of the spare material roll B. That is, the first rewind adsorption surface 20212a and the second rewind adsorption surface 20212b can independently adsorb different material strips E, thereby making the functions of the fifth adsorption element 20212 more diverse.

[0167] The sixth adsorption element 20222 has a third roll-changing adsorption surface 20222a and a fourth roll-changing adsorption surface 20222b that can be independently adsorbed. These can bring the same or similar beneficial effects as the fifth adsorption element 20212 having a first roll-changing adsorption surface 20212a and a second roll-changing adsorption surface 20212b that can be independently adsorbed. For details, please refer to the description in the above embodiments. This embodiment will not be repeated here.

[0168] It should be noted that the first driving component 20211 can be a lead screw and nut mechanism or a cylinder, as long as it can achieve the purpose of driving the fifth adsorption component 20212 to move closer to or further away from the sixth adsorption component 20222 along the first direction. This embodiment does not limit the first driving component 20211.

[0169] The structures of the second driving component 20221 and the third driving component 20231 described above may be the same as or similar to the structure of the first driving component 20211 described above. For details, please refer to the description in the above embodiments. This embodiment will not be repeated here.

[0171] The structure of the roll changing device 200 can be the same as that of any of the roll changing devices 200 described in the above embodiments, and can bring the same or similar beneficial effects. For details, please refer to the description of the roll changing device 200 in the above embodiments. This embodiment will not repeat the description here.

[0172] In this embodiment, since the winding device 200 has a simple structure and low cost, when the battery cell winding equipment 300 includes the winding device 200, the structure of the battery cell winding equipment 300 can be made simple and the cost can be kept low.
