[0032] See also Figure 1-Figure 3 In one embodiment of the present application, a winding device 100 is provided, which can realize the winding of a material strip 300. Specifically, the material strip 300 wound by the winding device 100 is a foil material strip coated with slurry for preparing lithium batteries. It should be understood that in some other embodiments, the type of the material strip 300 wound by the winding device 100 is not limited. For example, in some embodiments, the material strip 300 can also be a diaphragm material strip for preparing lithium batteries.

[0033] The winding device 100 includes a winding shaft 10, which is used to carry a barrel 400, and the barrel 400 is used to wind up the material strip 300. When winding up the material strip 300, the empty barrel 400 is carried on the winding shaft 10, and the winding shaft 10 drives the barrel 400 to rotate or the barrel 400 rotates relative to the winding shaft 10, and the material strip 300 can be wound onto the barrel 400, and the barrel 400 and the material strip 300 wound thereon together form a roll 200.

[0034] As described in the background technology, during the winding process of the existing foil material strip coated with slurry, due to various reasons, such as unreasonable tension taper setting, air being drawn in during high-speed winding, etc., the strip winding will be misaligned and poorly contrasted. When the strip winding is misaligned and poorly aligned, the strip will be misaligned in the width direction, that is, the strip will be larger in the width direction, which will cause the pole pieces to be scrapped in batches, resulting in waste of slurry and foil.

[0035] Further reading Figure 1 and Figure 2The winding device 100 further includes a detection mechanism 20, which includes a driving assembly 21 and a sensor 22, and the sensor 22 is connected to the driving assembly 21. The driving assembly 21 can drive the sensor 22 to reciprocate along the axial direction X of the winding shaft 10, so that the sensor 22 can detect the edges of the two ends of the rolled material roll 200 in the axial direction X.

[0036] According to the above configuration, during the winding process of the material strip 300, the control driving component 21 drives the sensor 22 to reciprocate in the axial direction X of the winding shaft 10. During the reciprocating movement of the sensor 22 in the axial direction X of the winding shaft 10, the sensor 22 can detect the two end edges of the material roll 200 in the axial direction X of the winding shaft 10. The position of the sensor 22 when detecting one side edge of the material roll 200 in the axial direction X is defined as the first position A, and the position of the sensor 22 when detecting the other side edge of the material roll 200 in the axial direction X is defined as the second position B. The distance between the first position A and the second position B is the actual width of the material roll 200 formed by winding. When the actual width exceeds the preset width range, the device can be controlled to stop or an alarm signal can be issued to avoid the situation where the dislocation of the wound material strip 300 is too large and causes batch scrapping, thereby reducing material waste and saving resources.

[0037] It should be noted that the above-mentioned preset width is a preset width value. Generally, when the material strip 300 is not wound onto the barrel 400, the width of the material strip 300 is L, and the allowable misalignment is ±a, then the preset width can be set to L+2a. It should also be noted that the actual width of the roll 200 will change during the winding process, and the control drive assembly 21 drives the sensor 22 to move and scan the roll 200 in real time, so that the actual width of the roll 200 can be detected in real time.

[0038] In some embodiments, the winding device 100 further includes a controller (not shown in the figure), and the sensor 22 is electrically connected to the controller. When the sensor 22 detects the edges of the two ends of the roll 200 in the axial direction X, the controller can know the position of the sensor 22, and obtain the actual width of the roll 200 according to the distance between the first position A and the second position B, and send a signal according to the relationship between the actual width and the preset width, such as sending an alarm signal to alarm or sending a stop signal to control the device to stop.

[0039] In some embodiments, the detection mechanism 20 includes a sensor 22, and the driving assembly 21 can drive the sensor 22 to reciprocate along the axial direction X of the reel 10 to detect the edges of the two ends of the material roll 200 in the axial direction X. When the material strip 300 is reeled, the driving assembly 21 can drive the sensor 22 to reciprocate in the axial direction X, from one end of the material roll 200 to the other end, to detect the two ends of the material roll 200 in real time. In this way, one sensor 22 can detect the two ends of the material roll 200, and the structure is simple.

[0040] It should be noted here that Figure 2 FIG. 4 illustrates the situation where the sensor 22 moves to the first position A, the second position B, and the intermediate position between the first position A and the second position B. FIG.

[0041] In some other embodiments, the detection mechanism 20 includes two sensors 22, and the driving assembly 21 can drive the two sensors 22 to reciprocate along the axial direction X of the winding shaft 10, so that one sensor 22 can detect the edge of one end of the material roll 200 in the axial direction X, and the other sensor 22 can detect the edge of the other end of the material roll 200 in the axial direction X. When the material strip 300 is wound, the driving assembly 21 can drive the two sensors 22 to reciprocate in the axial direction X, at which time one sensor 22 reciprocates at one end of the material roll 200, and the other sensor 22 reciprocates at the other end of the material roll 200, and the two sensors 22 cooperate to detect the two end edges of the material roll 200 in real time. Compared with the case where only one sensor 22 is provided, the travel of each sensor 22 can be reduced, thereby improving the detection efficiency.

[0042] Further, the driving assembly 21 includes a first driving assembly and a second driving assembly, one sensor 22 is drivingly connected to the first driving assembly, and another sensor 22 is drivingly connected to the second driving assembly. The first driving assembly and the second driving assembly respectively drive the sensors 22 connected thereto to reciprocate in the axial direction X of the winding shaft 10.

[0043] In some embodiments, the driving assembly 21 includes a first driving member and a transmission member, and the transmission member is transmission-connected between the first driving member and the sensor 22. It is conceivable that in other embodiments, the driving assembly 21 may also include only the first driving member, and omit the transmission member.

[0044] Specifically, the first driving member can be a motor or a cylinder, etc., and the specific setting mode of the first driving member is not limited. Meanwhile, the transmission member can be a gear transmission, a belt transmission, or a screw nut transmission, etc., and the specific setting mode of the transmission member is also not limited.

[0045] Optionally, the sensor 22 is a photoelectric sensor or an image sensor. Of course, in other embodiments, the type of the sensor 22 is not limited.

[0046] In some embodiments, see Figure 1 and Figure 3The winding device 100 further includes a rotating frame 30, and the winding device 100 includes two winding shafts 10 and two detection mechanisms 20, and the winding shafts 10 and the detection mechanisms 20 are both installed on the rotating frame 30. The rotating frame 30 can rotate around its own axis to drive the two winding shafts 10 to rotate, so that one of them is at the working station C and the other is at the roll changing station D. The winding shafts 10 and the detection mechanisms 20 are arranged in a one-to-one correspondence, and the detection mechanisms 20 can rotate synchronously with the winding shafts 10.

[0047] When the reel 10 is at the operation station C, the material tape 300 can be wound onto the barrel 400 carried by the reel 10; when the reel 10 is at the roll changing station D, the material roll 200 on the reel 10 can be replaced. That is, the operation station C is a station where the barrel 400 can be normally rewound, and the roll changing station D is a station where the material roll 200 is removed after the normal rewinding work is completed to install a spare barrel 400.

[0048] With the above arrangement, after the material roll 200 on the reel 10 at the work station C is finished, the rotating frame 30 drives the two reel 10 to rotate. The finished material roll 200 moves from the work station C to the reel changing station D, and the barrel 400 at the reel changing station D moves from the reel changing station D to the work station C. In this way, the reeling device 100 realizes the reel changing of the material roll 200 at the work station C, which can improve the work efficiency.

[0049] It should be noted here that since each winding shaft 10 is provided with a corresponding detection mechanism 20, when the winding shaft 10 is in the working station C, the sensor 22 of the corresponding detection mechanism 20 can detect the edges of both ends of the material roll 200 wound thereon, which makes the detection convenient.

[0050] Continue reading Figure 2 The detection mechanism 20 also includes a mounting seat 23, which is connected to the rotating frame 30. The driving component 21 is installed on the mounting seat 23, and the driving component 21 can drive the sensor 22 to reciprocate along the axial direction X of the winding shaft 10 relative to the mounting seat 23.

[0051] In some specific embodiments, the rotating frame 30 drives the two winding shafts 10 to rotate 180° to realize the switching of the winding shafts 10 between the working station C and the roll changing station D. That is, in the initial state, one winding shaft 10 is located at the working station C, and the other winding shaft 10 is located at the roll changing station D. After the rotating frame 30 rotates 180°, one winding shaft 10 can be located at the station where the other winding shaft 10 is located. It can be imagined that in other specific embodiments, the rotation angle of the rotating frame 30 is not limited, such as the rotation angle of the winding shaft 10 driven by the rotating frame 30 can be slightly less than 180° or slightly greater than 180°.

[0052] Further reading Figure 3 The winding device 100 also includes a pressing and cutting mechanism 40, which includes a cutter 41 and a pressure roller 42. The pressure roller 42 can press the material strip 300 on the barrel 400 at the roll changing station D onto the barrel 400 on the winding shaft 10 at the working station C. The cutter 41 can cut the material strip 300, and the cut material strip 300 can be connected to the barrel 400 at the working station C.

[0053] With the above arrangement, after the material roll 200 on the reel 10 at the work station C is finished, the rotating frame 30 drives the two reel 10 to rotate. The finished material roll 200 moves from the work station C to the reel changing station D, and the barrel 400 at the reel changing station D moves from the reel changing station D to the work station C. The pressing roller 42 can press the material strip 300 on the barrel 400 at the reel changing station D that has finished the work on the spare barrel 400 at the work station C. At this time, the material strip 300 is pressed by the combined action of the barrel 400 and the pressing roller 42, and the cutter 41 cuts off the pressed material strip 300. In addition, the cut material strip 300 is connected to the spare barrel 400. Specifically, the barrel 400 is provided with double-sided tape, and the material strip 300 is attached to the barrel 400 by the double-sided tape. Then, the material roll 200 at the roll changing station D is removed and a new spare material barrel 400 is installed. When the material roll 200 at the operation station C is completed again, the above steps are repeated to achieve the next roll change. In this way, the winding device 100 realizes the automatic roll change of the material roll 200 at the operation station C, thereby improving the work efficiency.

[0054] Furthermore, the winding device 100 further includes a frame 70 , and the rotating frame 30 and the pressing and cutting mechanism 40 are both installed on the frame 70 .

[0055] The winding device 100 further includes a swing arm 50, which is mounted on the frame 70, and a pressing and cutting mechanism 40 is mounted on the swing arm 50. The swing arm 50 can drive the pressing and cutting mechanism 40 to swing, so that the pressing and cutting mechanism 40 moves between the third position and the fourth position. When the pressing and cutting mechanism 40 is in the third position, the pressing and cutting mechanism 40 can press and cut the material strip 300. When the pressing and cutting mechanism 40 is in the fourth position, the pressing and cutting mechanism 40 allows the rotating frame 30 to rotate. That is, the third position is a cutting position where the pressing and cutting mechanism 40 presses and cuts the material strip 300, and the fourth position is an avoidance position. When the pressing and cutting mechanism 40 is in the fourth position, it will not interfere with the rotation of the rotating frame 30 and will not interfere with the normal winding of the material strip 300.

[0056] The pressing and cutting mechanism 40 further includes a second driving member, which is disposed on the swing arm 50, and the cutter 41 is connected to the second driving member, and the second driving member is used to drive the cutter 41 to move so as to cut the material strip 300. Specifically, when the swing arm 50 drives the pressing and cutting mechanism 40 to move to the third position, the second driving member drives the cutter 41 to rotate so as to extend and cut the material strip 300, so as to cut the material strip 300.

[0057] Continue reading Figure 3 The pressing and cutting mechanism 40 further includes a third driving member 43 and a connecting rod 44. The third driving member 43 is disposed on the swing arm 50. The pressing roller 42 is connected to the connecting rod 44. The third driving member 43 is used to drive the connecting rod 44 to move, thereby driving the pressing roller 42 to move, so as to press and hold the material strip 300. Specifically, when the swing arm 50 drives the pressing and cutting mechanism 40 to move to the third position, the third driving member 43 drives the connecting rod 44 to move, so as to drive the pressing roller 42 to press and hold the material strip 300.

[0058] Continue reading Figure 1 The winding device 100 further includes a traction mechanism 60 mounted on the frame 70, and the traction mechanism 60 is used to traction and support the material belt 300 so that the material belt 300 is wound onto the barrel 400. The setting of the traction mechanism 60 can traction the material belt 300 and prevent the material belt 300 from loosening, so as to facilitate the winding, cutting and rewinding of the material belt 300.

[0059] 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.

[0060] 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. Therefore, the protection scope of the utility model patent shall be based on the attached claims.
