[0044] As described in the background of this application, in related art, winding equipment typically includes a turntable, a winding needle mounted on the turntable, and several auxiliary mechanisms. The winding needle typically passes through a winding station and a non-winding station as it rotates with the turntable. The winding needle winds the battery cells at the winding station and performs finishing, gluing, or unloading at the non-winding station. Auxiliary mechanisms include a diaphragm cutting assembly, which includes a cutter that is used to cut the diaphragm after the cell is wound.

[0045] Some winding equipment requires different winding processes for battery cells. For each winding process, the cutter needs to cut the separator at different locations between the winding and non-winding stations. In related art, manual adjustments to the cutter's position for cutting the separator assembly are often employed to meet the requirements of different winding processes. However, this method is labor-intensive and time-consuming, which can lead to reduced production efficiency.

[0046] In view of the above-mentioned problems, the present application provides a winding device to solve the problem of manually changing the position of the cutter in the related art.

[0047] The technical solution of this application will be further described below with reference to specific embodiments and drawings:

[0048] like Figure 1 As shown, the winding apparatus includes a rotating member 1, a winding needle 2, and a slit tape assembly 3. The rotating member 1 is rotatably mounted, with its rotational axis being a first rotational axis. The winding needle 2 is rotatably mounted on the rotating member 1, offset from the first rotational axis. As the winding needle 2 rotates with the rotating member 1 about the first rotational axis, it passes through a winding station 4 and a non-winding station. The winding needle 2 is used to wind the tape 5 while in the winding station 4. The arrangement direction between the winding station 4 and the non-winding station is a first direction.

[0049] like Figure 1 and Figure 2 As shown, the cutting strip assembly 3 includes a cutter 31, a cutting drive 32 and a shift drive 33. The shift drive 33 is used to drive the cutter 31 to move in a first direction (such as Figure 2 The cutting drive member 32 is used to drive the cutter 31 at the preset position to move in a second direction (such as the X direction) different from the first direction. Figure 2 The cutter 31 moves in the Y direction in the middle of the material strip 5 so that the cutter 31 cuts the material strip 5.

[0050] In the present application, when the winding device is used to wind battery cells, the material strip 5 can be a diaphragm or an electrode, and the winding needle 2 rotates with the rotating member 1 to the winding station 4 to wind the battery cells, that is, to wind the diaphragm and the electrode. Since the cutting strip assembly 3 in the winding device includes a cutter 31, a cutting drive 32, and a position-shifting drive 33, and since the position-shifting drive 33 is used to drive the cutter 31 to move in a first direction so that the cutter 31 is located at a preset position, the cutting drive 32 is used to drive the cutter 31 located at the preset position to move in a second direction different from the first direction so that the cutter 31 cuts the material strip 5. Therefore, depending on the different winding processes, the cutter 31 can be driven to move along the arrangement direction between the winding station 4 and the non-winding station by the shifting drive 33, and the cutter 31 can be driven to the preset position corresponding to the different winding processes. In this way, after the winding needle 2 has wound the battery cell, the cutter 31 located at the corresponding preset position is driven to move along the second direction by the cutting drive 32, so that the cutter 31 can cut the material strip to form a battery cell.

[0051] According to the above, the present application can drive the cutter 31 to move along the arrangement direction between the winding station 4 and the non-winding station through the position-changing drive member 33 according to the different winding processes, and can drive the cutter 31 to the preset position corresponding to the corresponding winding process. It has strong compatibility and high automation performance. In this way, there is no need to manually change the position of the cutting tape assembly 3 to change the position of the cutter 31, which is conducive to reducing labor intensity and time consumption. There is no need for manual tedious operations, which avoids delays caused by manual operations and thus helps to improve production efficiency.

[0052] Regarding the structure of the rotating part 1, in the embodiment of the present application, the rotating part 1 can be a rotating disk, a rotating frame, a rotating rod, etc. The structural setting of the rotating part 1 is relatively flexible. Specifically, it can be set according to actual needs. The embodiment of the present application does not make specific limitations on this.

[0053] For non-winding stations, in the embodiment of the present application, Figure 1 As shown, the non-winding station may include a blanking station 6; or, as shown Figure 1 As shown, the non-winding station can include a gluing station 7 and a blanking station 6; alternatively, the non-winding station can include a gluing and blanking station, i.e., gluing and blanking are performed at the same station. The configuration of the non-winding station is relatively flexible and can be specifically configured according to actual needs. This embodiment of the present application does not specifically limit this.

[0054] Regarding the number of winding needles 2, in the embodiment of the present application, one, two, or three winding needles 2 can be provided. When multiple winding needles 2 are provided, each winding needle 2 must be located at a different workstation at the same time. The number of winding needles 2 is flexible and can be set according to actual needs. This embodiment of the present application does not impose any specific restrictions on this.

[0055] Regarding the type of the material tape 5, in the embodiment of the present application, the material tape 5 can also be an insulating tape, a heat dissipation tape, or a marking tape, etc., depending on the application scenario of the winding device. The type of the material tape 5 is relatively flexible and can be determined specifically according to the application scenario of the winding device.

[0056] As for the types of the cutting drive 32 and the transposition drive 33, in the embodiment of the present application, the cutting drive 32 and the transposition drive 33 can be any one of an electric cylinder, a pneumatic cylinder and a hydraulic cylinder. The type selection of the two is relatively flexible. Specifically, it can be selected according to actual needs. The embodiment of the present application does not make specific restrictions on this.

[0057] Furthermore, the cutter 31 is provided on a transposition drive 33, which is provided on a cutting drive 32, and the cutting drive 32 is configured to drive the cutter 31 to move in the second direction via the transposition drive 33. Alternatively, the cutter 31 is provided on the cutting drive 32, which is provided on the transposition drive 33, and the transposition drive 33 is configured to drive the cutter 31 to move in the first direction via the cutting drive 32.

[0058] With this arrangement, the cutter 31, the cutting drive member 32 and the transposition drive member 33 are driven and connected in sequence. In this way, there is no need to perform complex transmission settings among the cutter 31, the cutting drive member 32 and the transposition drive member 33 to a certain extent, which is conducive to simplifying the transmission settings among the cutter 31, the cutting drive member 32 and the transposition drive member 33, and is conducive to facilitating the settings among the cutter 31, the cutting drive member 32 and the transposition drive member 33.

[0059] In a preferred embodiment, Figure 2 As shown, the cutter 31 is arranged on the transposition drive 33 , and the transposition drive 33 is arranged on the cutting drive 32 .

[0060] With such an arrangement, the cutter 31, the cutting drive 32 and the shifting drive 33 can form a nested structure to a certain extent, which is conducive to making the structure of the entire cutting tape assembly 3 more compact, helping to reduce the space occupied by the cutting tape assembly 3, and thus helping to enhance the flexibility of the setting of the cutting tape assembly 3.

[0061] In other embodiments, the cutter 31 is provided on the cutting drive 32 and also on the transposition drive 33, and the cutting drive 32 and the transposition drive 33 are provided independently of each other. In this arrangement, the cutting drive 32 and the transposition drive 33 only need to drive the cutter 31, which helps reduce the weight of the cutting drive 32 and the transposition drive 33, thereby facilitating the driving of the cutter 31 by the cutting drive 32 and the transposition drive 33.

[0062] Furthermore, if Figure 2As shown, the cutting strip assembly 3 further includes a movable member 34, and the cutter 31 moves along a first direction (such as Figure 2 The X direction in the figure) is slidably arranged on the movable member 34, the shift drive member 33 is used to drive the cutter 31 to move along the first direction on the movable member 34, and the cutting drive member 32 is used to drive the movable member 34 to move along the second direction (such as Figure 2 The cutter 31 moves in the second direction.

[0063] The cutter 31 is slidably arranged on the movable part 34 along the first direction. In this way, when the shift drive part 33 drives the cutter 31 to move, the stability of the cutter 31 in the first direction can be enhanced through the guidance of the movable part 34, which is conducive to reducing the position error of the cutter 31 caused by shaking or irregular movement.

[0064] In the embodiment of the present application, the cutter 31 can be slidably set on the movable part 34 through any sliding matching structure such as a guide rail and a slider, a slider and a sliding groove, a sliding groove and a guide rail. The sliding matching structure between the cutter 31 and the movable part 34 is relatively flexible. Specifically, it can be set according to actual needs. The embodiment of the present application does not make specific limitations on this.

[0065] Further, if Figure 2 As shown, the cutting tape assembly 3 further includes a fixed seat 35, the movable member 34 is slidably arranged on the fixed seat 35 along the second direction, and the cutting drive member 32 is used to drive the movable member 34 on the fixed seat 35 along the second direction (such as Figure 2 Y direction in the image.

[0066] The movable member 34 is slidably arranged on the fixed seat 35 along the second direction. In this way, when the cutting drive member 32 drives the cutter 31 to move through the movable member 34, the fixed seat 35 guides the movable member 34 along the second direction, which can enhance the stability of the cutter 31 in the second direction, and is conducive to reducing cutting errors caused by shaking or irregular movement.

[0067] In the embodiment of the present application, the movable part 34 can be slidably set on the fixed seat 35 through any sliding matching structure such as a guide rail and a slider, a slider and a sliding groove, a sliding groove and a guide rail. The sliding matching structure between the movable part 34 and the fixed seat 35 is relatively flexible. Specifically, it can be set according to actual needs. The embodiment of the present application does not make specific limitations on this.

[0068] For the transmission member between the transposition drive member 33 and the cutter 31, further, as Figure 2 As shown, the shift drive member 33 and the cutter 31 are connected to each other via a belt drive mechanism 36 .

[0069] With such an arrangement, on the one hand, the belt drive mechanism 36 can provide relatively smooth power transmission, so that the cutter 31 moves more smoothly and steadily between the winding station 4 and the non-winding station, which helps to ensure that the cutter 31 accurately reaches the preset position, reduces the position deviation caused by unstable transmission, and thus helps to improve the cutting accuracy.

[0070] Secondly, the belt drive mechanism 36 generally produces relatively little noise, which can improve the working environment, reduce interference with operators, and improve work efficiency. At the same time, the belt drive mechanism 36 takes up relatively little space, which is conducive to achieving a compact design of the cutting belt assembly 3.

[0071] Thirdly, the belt drive mechanism 36 can make the cutter 31 have a wider range of motion, which helps to meet the requirements of cutting diaphragms in different winding processes.

[0072] In addition, it should be noted that since the belt transmission mechanism 36 is a prior art, the specific structure of the belt transmission mechanism 36 will not be described in detail in the embodiment of the present application.

[0073] In other embodiments, the transposition drive member 33 and the cutter 31 may be connected to each other via a screw-nut mechanism or a rack-and-pinion mechanism, or the transposition drive member 33 and the cutter 31 may be directly connected. The arrangement of the transmission member between the transposition drive member 33 and the cutter 31 is relatively flexible and can be specifically arranged according to actual needs.

[0074] For the transmission member between the cutting drive member 32 and the movable member 34, further, as Figure 2 As shown, the cutting drive member 32 has a second rotation axis, and the cutting drive member 32 is provided with an insertion portion 37 that is arranged offset from the second rotation axis.

[0075] The movable member 34 is provided with a transmission member 38, and the transmission member 38 is provided with a waist-shaped hole 381 or a waist-shaped groove for inserting the insertion portion 37. The length direction of the waist-shaped hole 381 or the waist-shaped groove is respectively aligned with the second direction (such as Figure 2 The Y direction in the figure) and the extension direction of the second rotation axis (such as Figure 2 The X direction in the figure is perpendicular to the X direction in the figure.

[0076] With such arrangement, when the cutting drive member 32 drives the insertion portion 37 to rotate around the second rotation axis, the insertion portion 37 will move in the waist-shaped hole 381 or the waist-shaped groove along the length direction of the waist-shaped hole 381 or the waist-shaped groove, so that the movable member 34 can be driven to move in the second direction through the cooperation between the insertion portion 37 and the inner side wall of the waist-shaped hole 381 or the waist-shaped groove, and then the cutter 31 can be driven to move in the second direction, that is, the rotational action can be converted into a direct action along the second direction through the cooperation between the insertion portion 37 and the waist-shaped hole 381 or the waist-shaped groove. Compared with the cutting drive member 32 driving the movable member 34 to move in the second direction by direct action along the second direction, this is conducive to reducing the space occupied by the cutting belt assembly 3 in the second direction, facilitating the arrangement of the cutting belt assembly 3 in the second direction, and also facilitating the rotational action output by the cutting drive member 32 to drive the movable member 34 to move in a direct motion.

[0077] In the embodiment of the present application, the insertion portion 37 can be a cam follower or a boss. The structural setting of the insertion portion 37 is relatively flexible. Specifically, it can be set according to actual needs. The embodiment of the present application does not make specific limitations on this.

[0078] Regarding the arrangement between the transmission member 38 and the movable member 34, in the embodiment of the present application, the transmission member 38 and the movable member 34 can be integrally formed or separately formed and then connected. The arrangement between the transmission member 38 and the movable member 34 is relatively flexible and can be specifically arranged according to actual needs. This embodiment of the present application does not specifically limit this.

[0079] In other embodiments, the cutting drive member 32 and the movable member 34 may be connected to each other via a screw-nut mechanism or a rack-and-pinion mechanism, or they may be directly connected to each other. The arrangement of the transmission member between the cutting drive member 32 and the movable member 34 is relatively flexible and can be specifically arranged according to actual needs.

[0080] Further, if Figure 2 As shown, a rotating disk 39 is provided on the cutting drive member 32 , the central axis of the rotating disk 39 is colinear with the second rotation axis, and the inserting portion 37 is provided on the rotating disk 39 .

[0081] Since the rotating disk 39 usually has a relatively uniform mass distribution, the center of gravity of the rotating disk 39 is relatively stable during the rotation process, and the rotating disk 39 can provide stable rotation. Through the rotating disk 39, it is helpful to drive the movable part 34 to move stably along the second direction, and then it is helpful to drive the cutter 31 to move stably along the second direction, which is helpful to improve the cutting accuracy.

[0082] In other embodiments, the cutting drive member 32 and the inserting portion 37 may be connected via a connecting rod. This configuration can simplify the connection structure between the cutting drive member 32 and the inserting portion 37, thereby facilitating the processing of the connection structure.

[0083] Regarding the above-mentioned preset position of the cutter 31, further, the preset position includes a first preset position and a second preset position, the first preset position is located at the winding station 4 ( Figure 1 As shown), the second preset position is located between the winding station 4 and the non-winding station ( Figure 3 As shown), the shift drive 33 is used to drive the cutter 31 to switch between the first preset position and the second preset position.

[0084] So set up, such as Figure 1 As shown, in the winding process where the material strip 5 does not pass through the center seam of the winding needle 2, the cutting knife 31 is driven to be located at the first preset position, which is conducive to facilitating the cutting of the material strip 5 in the winding process. Figure 3 As shown, during the winding process where the material strip 5 passes through the center seam of the winding needle 2, the cutter 31 is driven to the second preset position, which facilitates cutting of the material strip 5 during the winding process. At the same time, the preset position of the cutter 31 is switched by the shifting drive 33, which not only helps to reduce the labor intensity and time consumption of switching the preset positions, and improve production efficiency, but also facilitates the position switching of the cutter 31.

[0085] like Figure 1 As shown, the winding device further includes a roller assembly 8 located upstream of the cutter 31 in the transmission direction of the material strip 5, as shown in FIG. Figure 1 and Figure 4 As shown, the roller assembly 8 includes a pressure roller 81 and a pressure roller driving member 82. The pressure roller driving member 82 is used to drive the pressure roller 81 to move close to the winding needle 2, so that the pressure roller 81 and the winding needle 2 can jointly press the material strip 5 located therebetween.

[0086] When the material strip 5 does not pass through the center seam of the winding needle 2, the material strip 5 may become loose or deflected. Therefore, in this case, the pressure roller 81 is driven by the pressure roller driving member 82 to move close to the winding needle 2, so that the pressure roller 81 and the winding needle 2 jointly press the material strip 5 located therebetween. This can effectively prevent the material strip 5 from becoming loose or deflected, ensure that the material strip 5 is always in a tensioned state, and is conducive to improving the quality and efficiency of winding.

[0087] Further, if Figure 4 As shown, the supporting roller assembly 8 further includes a first movable support 83 and a second movable support 84 . The first movable support 83 is transmission-connected to the pressure roller driving member 82 , and the pressure roller 81 is disposed on the second movable support 84 .

[0088] The length direction of the pressure roller 81 (as shown in the right Figure 4The X direction in the right direction) and the driving direction of the roller drive 82 (such as the right Figure 4 The direction perpendicular to the length direction of the pressure roller 81 and the driving direction of the pressure roller driving member 82 is the third direction (such as the right Figure 4 The second movable support 84 is movably provided on the first movable support 83 along the third direction.

[0089] Because the length of the pressure roller 81 extends in the same direction as the axial direction of the winding needle 2, and the driving direction of the pressure roller driver 82 is perpendicular to the axial direction of the winding needle 2, a third direction perpendicular to the length of the pressure roller 81 and the driving direction of the pressure roller driver 82 extends in the same direction as the radial direction of the winding needle 2. Thus, the second movable support 84 is movably mounted on the first movable support 83 along the third direction, thereby enabling the radial position of the pressure roller 81 to be adjusted in accordance with the radial dimensions of the winding needle 2, so that the pressure roller 81 and the winding needle 2 can jointly compress the material strip 5 located therebetween. This facilitates enhancing the adaptability of the support roller assembly 8 to winding needles 2 of varying radial dimensions, thereby enhancing the applicability of the support roller assembly 8.

[0090] Furthermore, if Figure 5 As shown, a guide groove 831 is provided on the first movable support 83 , and the second movable support 84 is movably provided in the guide groove 831 along the third direction.

[0091] The guide groove 831 provides a clear movement path for the second movable support 84, making its movement in the third direction more precise. This ensures that the pressure roller 81 always moves in the predetermined direction when moving toward or away from the winding needle 2, avoiding deviation or shaking, and improving the precision and stability of the pressure roller 81's movement.

[0092] For the roller assembly 8, further, as Figure 4 As shown, the supporting roller assembly 8 further includes a fixed support 85 , the pressure roller driving member 82 is disposed on the fixed support 85 , and an elastic member 86 is disposed between the fixed support 85 and the first movable support 83 .

[0093] With such an arrangement, on the one hand, when the pressure roller 81 moves close to the winding needle 2 and presses the material strip 5, the elastic member 86 can play a buffering role, avoiding rigid collision between the pressure roller 81 and the winding needle 2, reducing the impact and damage to the pressure roller 81, the winding needle 2 and other related components, and extending the service life of the equipment.

[0094] On the other hand, the elastic member 86 can automatically adjust the pressing force between the pressure roller 81 and the winding needle 2 according to the thickness and winding state of the material strip 5, so as to ensure that the appropriate pressing force can be maintained under different circumstances, thereby improving the quality and stability of the winding.

[0095] As for the elastic member 86, in the embodiment of the present application, the elastic member 86 can be a spring or an elastic rubber block, etc. The type of the elastic member 86 can be selected flexibly. Specifically, it can be selected according to actual usage requirements. The embodiment of the present application does not make any specific restrictions on this.
