[0052] As described in the background of this application, when manufacturing battery cells using a winding process, tape needs to be bonded to the surface of the electrode. This tape is typically provided by a tape preparation device. In related art, after unwinding the tape from the old roll, the tape preparation device typically requires multiple drive components to complete the preparation of the tape unwound from the new roll.

[0053] However, not only do multiple driving members lead to an increase in manufacturing costs, but controlling the multiple driving members to drive also leads to an increase in control difficulty.

[0054] Example 1

[0055] In view of the above-mentioned problems, the present application provides a material preparation device to solve the problem in the related art that multiple driving parts lead to increased manufacturing costs and increased control difficulty.

[0056] The technical solution of this application will be further described below with reference to specific embodiments and drawings:

[0057] like Figure 1 As shown, the material preparation device 100 includes an unwinding mechanism and a material preparation mechanism, wherein the unwinding mechanism includes a first unwinding shaft 1 and a second unwinding shaft 2 that are spaced apart, and the first unwinding shaft 1 and the second unwinding shaft 2 are both used to install the material roll 3.

[0058] like Figure 1 and Figure 2 As shown, the material preparation mechanism includes a driving component 4, a first material clamping component 5, a second material clamping component 6 and a material pulling component 7, wherein the driving component 4 includes a driving member 41, and the driving member 41 is used to drive the first material clamping component 5 and the second material clamping component 6 to move, so that the first material clamping component 5 passes through the first material preparation position and the first material pulling position, and the second material clamping component 6 passes through the second material preparation position and the second material pulling position.

[0059] The first clamping assembly 5 located at the first material preparation position is used to clamp the material strip 31 unwound from the material roll 3 on the first unwinding shaft 1. The first clamping assembly 5 located at the first material pulling position allows the material pulling assembly 7 to pull the material strip 31 clamped by it. The second clamping assembly 6 located at the second material preparation position is used to clamp the material strip 31 unwound from the material roll 3 on the second unwinding shaft 2. The second clamping assembly 6 located at the second material pulling position allows the material pulling assembly 7 to pull the material strip 31 clamped by it.

[0060] In the present application, when the material preparation device 100 is applied to the battery cell winding process, the first unwinding shaft 1 and the second unwinding shaft 2 are both used to install the material roll 3 of the tape, that is, the material strip 31 unwound from the material roll 3 is the tape. In the first case, the material roll 3 on the first unwinding shaft 1 has been unwound, and a new material roll 3 is installed on the second unwinding shaft 2. When preparing materials in this case, since the driving member 41 is used to drive the second clamping assembly 6 to move so that the second clamping assembly 6 passes through the second material preparation position and the second material pulling position, and since the second clamping assembly 6 located at the second material preparation position is used to clamp the material strip 31 unwound from the material roll 3 on the second unwinding shaft 2, the second clamping assembly 6 located at the second material pulling position is for the pulling assembly 7 to pull the material strip 31 clamped by itself. Therefore, during the material preparation process, the second clamping assembly 6 can be driven to the second material preparation position by the driving member 41 so that the second clamping assembly 6 clamps the tape unwound from the material roll 3 on the second unwinding shaft 2. Subsequently, the second clamping assembly 6 can be driven to the second pulling position by the driving member 41, so that the pulling assembly 7 can pull the adhesive tape clamped by the second clamping assembly 6, thereby completing the preparation of a new adhesive tape. Therefore, in this case, the preparation device 100 can complete the preparation of a new adhesive tape by driving a single driving member 41.

[0061] In the second case, the tape roll on the second unwinding shaft 2 has been unwound, and a new tape roll is mounted on the first unwinding shaft 1. The preparation process in this case is the same as that in the first case and will not be repeated here. Therefore, in this case, the preparation device 100 can also complete the preparation of a new tape by driving a single driving member 41.

[0062] In summary, since the preparation device 100 in this application can complete the preparation of new tape by driving a driving member 41, this application can reduce the number of driving members 41, thereby reducing manufacturing costs. At the same time, since it is easier to control one driving member 41 for driving, it can also reduce the control difficulty.

[0063] Regarding the type of the material tape 31, in the embodiment of the present application, the material tape 31 can also be an insulating tape, a heat dissipation tape, or a marking tape, etc., depending on the application scenario of the material preparation device 100. That is, the material roll 3 can be an insulating tape roll, a heat dissipation tape roll, or a marking tape roll, etc. The type of the material tape 31 is relatively flexible and can be determined specifically according to the application scenario of the material preparation device 100.

[0064] Regarding the driving member 41, in the embodiment of the present application, the driving member 41 can be an electric cylinder, a pneumatic cylinder or a hydraulic cylinder. The type of the driving member 41 can be selected flexibly. Specifically, it can be selected according to actual needs. The embodiment of the present application does not make any specific restrictions on this.

[0065] For the first clamping component 5, the second clamping component 6 and the pulling component 7, in the embodiment of the present application, the structural settings of the first clamping component 5, the second clamping component 6 and the pulling component 7 are relatively flexible. Specifically, they can be set according to actual needs, and the embodiment of the present application does not make specific limitations on this.

[0066] Furthermore, if Figure 1 As shown, the direction in which the first unwinding shaft 1 and the second unwinding shaft 2 are spaced apart is a first direction (eg Figure 1 In the Y direction), the first clamping component 5 and the second clamping component 6 are spaced apart in the first direction.

[0067] The direction perpendicular to the first direction is the second direction (e.g. Figure 1 The driving member 41 is used to drive the first clamping assembly 5 and the second clamping assembly 6 to move along the second direction.

[0068] In this arrangement, on the one hand, since the first unwinding shaft 1 and the second unwinding shaft 2 are spaced apart in the first direction, the first clamping component 5 and the second clamping component 6 are spaced apart in the first direction. This allows the layout of the clamping component to correspond to the layout of the unwinding shaft, making it convenient for the clamping component to accurately clamp the material strip 31 unwound from the material roll 3 on the corresponding unwinding shaft, which is beneficial to improving the accuracy and stability of clamping.

[0069] On the other hand, the driving member 41 drives the first clamping assembly 5 and the second clamping assembly 6 to move in a second direction perpendicular to the first direction. This makes the driving direction clear and avoids the confusion and uncertainty that may be caused by driving in multiple directions at the same time. At the same time, moving in a single direction can simplify the drive control and improve the accuracy and reliability of the movement. In addition, the second direction is perpendicular to the first direction, which is also conducive to reducing the space occupied by the clamping assembly in the first direction and facilitating the arrangement of the clamping assembly in the first direction.

[0070] In other embodiments, the angle between the second direction and the first direction can be an acute angle or an obtuse angle, that is, between the second direction and the first direction. In this case, the angle between the second direction and the first direction can be any value, which is conducive to facilitating the setting between the second direction and the first direction.

[0071] Furthermore, if Figure 1 As shown, the driving assembly 4 also includes a transmission structure 42, which is transmission-connected between the first clamping assembly 5 and the second clamping assembly 6 and the driving member 41. The driving member 41 is used to drive the first clamping assembly 5 and the second clamping assembly 6 to move in opposite directions through the transmission structure 42.

[0072] The driving member 41 drives the first clamping component 5 and the second clamping component 6 to move in opposite directions through the transmission structure 42, so that when one clamping component is performing a pulling operation at the pulling position, the other clamping component can simultaneously perform a preparing operation at the preparing position, thereby achieving continuous operation, helping to reduce waiting time, greatly shortening the preparation cycle, and improving the overall preparation efficiency.

[0073] In other embodiments, the driving member 41 can also drive the first clamping component 5 and the second clamping component 6 to move in the same direction. In this case, the two clamping components will be located at the preparation position or the pulling position at the same time. At the same time, there is no need to set up a transmission structure 42. The driving member 41 can directly drive the two clamping components to move, which is conducive to simplifying the structural composition of the driving component 4 and facilitating the processing and manufacturing of the driving component 4.

[0074] Furthermore, if Figure 3 As shown, the transmission structure 42 is a belt transmission structure, and the transmission structure 42 includes a belt 421, a belt 422 along the second direction (such as Figure 3 The driving wheel 422 and the driven wheel 423 are spaced apart (in the X direction in FIG), and the belt 421 is sleeved on the outer sides of the driving wheel 422 and the driven wheel 423.

[0075] In the first direction (such as Figure 3 In the Y direction), the belt 421 includes two belt segments respectively located on both sides of the driving wheel 422 and the driven wheel 423, and the first clamping component 5 and the second clamping component 6 are respectively connected to the two belt segments.

[0076] With such an arrangement, firstly, the belt transmission structure facilitates the driving member 41 to drive the first clamping assembly 5 and the second clamping assembly 6 to move in opposite directions.

[0077] Secondly, since the belt drive structure is compact and occupies little space, the positions of the driving wheel 422, the driven wheel 423 and the belt 421 can be flexibly arranged according to the overall layout requirements of the material preparation device 100, making the space utilization of the material preparation device 100 more efficient.

[0078] Again, the contact between the belt 421 and the driving wheel 422 and the driven wheel 423 is relatively soft, which can achieve smooth transmission. This stability can ensure that the first clamping assembly 5 and the second clamping assembly 6 will not experience severe vibration or impact during movement, thereby improving the accuracy and stability of clamping.

[0079] Finally, the belt drive structure is lower in cost than other transmission methods and can effectively reduce manufacturing costs.

[0080] In other implementations, the transmission structure 42 can also be a gear rack structure, and the transmission structure 42 includes a gear and two racks respectively arranged on both sides of the radial direction of the gear, and the two racks are engaged with the gear, and the first clamping component 5 and the second clamping component 6 are respectively connected to the two racks.

[0081] Such arrangement, on the one hand, facilitates the driving member 41 to drive the first clamping assembly 5 and the second clamping assembly 6 to move in opposite directions through the gear rack structure.

[0082] On the other hand, the rack and pinion structure enables precise linear motion control. The rotational motion of the gear is converted into linear movement of the clamping assembly through meshing with the rack. Its high transmission accuracy can ensure accurate position control of the first clamping assembly 5 and the second clamping assembly 6 in the second direction, thereby improving the accuracy of the material preparation process.

[0083] In a preferred embodiment, the belt transmission structure is a synchronous belt transmission structure.

[0084] Such an arrangement can achieve strictly synchronous reverse movement of the two clamping components, ensure the precise coordination of the movements of the two clamping components, and help improve the efficiency and quality of material preparation.

[0085] In other embodiments, the belt transmission structure may also be a V-belt transmission structure or a poly-V-belt transmission structure. The structural setting of the belt transmission structure is relatively flexible and can be specifically set according to actual needs.

[0086] For the drive assembly 4, further, as Figure 1 and Figure 4 As shown, the driving assembly 4 further includes a driving structure 43 for driving the first clamping assembly 5 and the second clamping assembly 6 to move along a first direction so that the first clamping assembly 5 and the second clamping assembly 6 alternately dock with the pulling assembly 7 .

[0087] With such an arrangement, the driving structure 43 can ensure that the pulling component 7 and the first clamping component 5 and the second clamping component 6 can be accurately docked in the first direction, thereby helping to ensure the stability and accuracy of the pulling process and helping to reduce the occurrence of uneven pulling or damage of the material strip 31.

[0088] In other embodiments, when the material pulling assembly 7 is movably arranged in the first direction, the driving structure 43 may not be provided, and the material pulling assembly 7 can be alternately docked with the first material clamping assembly 5 and the second material clamping assembly 6 by moving the material pulling assembly 7 in the first direction. Such an arrangement is conducive to simplifying the structural composition of the driving assembly 4 and facilitating the processing and manufacturing of the driving assembly 4.

[0089] Of course, in other embodiments, when the material pulling component 7 is movably arranged in the first direction, a driving structure 43 may also be provided, so as to help improve the docking efficiency between the material clamping component and the material pulling component 7.

[0090] In other embodiments, the first clamping assembly 5, the second clamping assembly 6, and the pulling assembly 7 are all fixedly arranged in the first direction. In this case, when the pulling assembly 7 performs the pulling operation, it is not necessary to dock with the first clamping assembly 5 and the second clamping assembly 6. This arrangement not only helps to simplify the structure of the driving assembly 4 and facilitates the processing and manufacturing of the driving assembly 4, but also facilitates the arrangement of the pulling assembly 7.

[0091] Furthermore, if Figure 1 、 Figure 2 and Figure 3 As shown, the material preparation device 100 also includes a mounting base 8, a movable seat 9 arranged on the mounting base 8 and guided along the first direction, the driving member 41 and the transmission structure 42 are both arranged on the movable seat 9, the first material clamping component 5 and the second material clamping component 6 are both guided on the movable seat 9 along the second direction, the first material clamping component 5 or the second material clamping component 6 is transmission-connected to the driving structure 43, and the first material clamping component 5 and the second material clamping component 6 are used to realize movement along the first direction through the movable seat 9.

[0092] In this arrangement, the first clamping assembly 5 and the second clamping assembly 6 are moved in the first direction by the movable seat 9, so that the movement of the two clamping assemblies is more coordinated and consistent. In this way, during the material preparation process, this coordinated movement can improve the overall efficiency and stability of the device and ensure the smooth progress of the material preparation operation.

[0093] In other embodiments, the first clamping assembly 5 and the second clamping assembly 6 can also be guided along the first direction and arranged on the mounting base 8. In this way, there is no need to set the movable seat 9, which is conducive to simplifying the structure of the material preparation device 100, reducing manufacturing costs, and facilitating processing and manufacturing.

[0094] Furthermore, if Figure 1 、 Figure 3 and Figure 4 As shown, the driving structure 43 includes a guide recess 431 and a guide portion 432 inserted in the guide recess 431. The guide portion 432 is arranged on the first clamping component 5, and the guide recess 431 is arranged on the mounting base 8. The guide portion 432 and the guide recess 431 are guided and matched along the guiding direction of the guide recess 431.

[0095] like Figure 5 As shown, the guide recess 431 includes an inclined guide section 4311, and the guiding direction of the inclined guide section 4311 (as shown in FIG. Figure 5 A direction in the second direction (such as Figure 5The X direction in the figure) gradually moves toward the first direction (such as Figure 5 Y direction in the tilt setting.

[0096] In this way, for example, when the material roll 3 on the first unwinding shaft 1 is unwound and a new material roll 3 is installed on the second unwinding shaft 2, first, as shown in FIG. Figure 1 As shown, the first clamping assembly 5 is located at the first material pulling position and docked with the material pulling assembly 7, and the second clamping assembly 6 is located at the second material preparation position and clamps the material strip 31 unwound from the material roll 3 on the second unwinding shaft 2.

[0097] Then, the driving member 41 drives the first clamping assembly 5 along the positive direction of the second direction (eg Figure 1 X1 direction in the figure) and drives the second clamping assembly 6 to move in the opposite direction of the second direction (such as Figure 1 During this movement, the guide portion 432 on the first clamping assembly 5 also moves within the inclined guide section 4311 along the guiding direction of the inclined guide section 4311. Thus, the movable seat 9 can be driven to move along the first direction through the guiding cooperation between the inclined guide section 4311 and the guide portion 432.

[0098] like Figure 6 As shown, when the first clamping component 5 moves to the first preparation position, the second clamping component 6 moves to the second pulling position, and the second clamping component 6 docks with the pulling component 7 in the first direction so that the pulling component 7 can pull the material strip 31 clamped thereon to complete the preparation.

[0099] From the above description, it can be seen that setting the driving structure 43 as a guide recess 431 and a guide portion 432 can not only realize the transmission connection between the driving structure 43 and the first clamping component 5, but also when the driving member 41 drives the two clamping components to move in the second direction, the driving structure 43 can also drive the two clamping components to move in the first direction, that is, the two clamping components can move in the first direction and the second direction at the same time, which is conducive to further improving the efficiency of material preparation and further shortening the material preparation cycle.

[0100] Regarding the guide portion 432, in the embodiment of the present application, the guide portion 432 can be a cam follower or a guide rod, etc. The structural setting of the guide portion 432 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.

[0101] In other embodiments, the driving structure 43 may further include a guide rod and a guide cylinder sleeved on the guide rod, the guide rod is arranged on the mounting base 8, the guide cylinder is arranged on the first clamping component 5, and the angle between the length direction of the guide rod and the second direction may be an acute angle or an obtuse angle.

[0102] With such arrangement, the driving structure 43 can not only drive the two clamping assemblies to move along the first direction, but also the driving structure 43 can share a portion of the force borne by the clamping assemblies, thereby improving the bearing capacity of the entire structure.

[0103] In other embodiments, the driving structure 43 may also be a handle provided on the movable seat 9, so that the movable seat 9 can be manually driven to move along the first direction by the handle. Such a configuration can simplify the structure of the driving structure 43 and facilitate the processing of the driving structure 43.

[0104] Furthermore, if Figure 5 As shown, the guide recess 431 further includes two straight guide segments 4312, which are connected to both ends of the guide direction of the inclined guide segment 4311. The guide direction of the straight guide segment 4312 is along the second direction (such as Figure 5 The X direction in FIG.

[0105] With such arrangement, when the clamping assembly is located at the material preparation position and the material pulling position, the guide portion 432 can be located in the straight guide section 4312, and since the guide portion 432 can be stably maintained at a certain position on the straight guide section 4312, the straight guide section 4312 is used to facilitate the clamping assembly to be stably maintained at the material preparation position and the material pulling position.

[0106] Furthermore, if Figure 3 and Figure 4 As shown, the guide recess 431 is a guide groove.

[0107] With such a configuration, since the guide groove is relatively easy to process and can be formed on the corresponding component by conventional processing methods such as milling and cutting, it is beneficial to reduce the manufacturing difficulty and cost of the guide recess 431 and improve production efficiency.

[0108] In other embodiments, the guide recess 431 may also be a guide hole.

[0109] With such arrangement, the guide hole can not only guide the guide portion 432 , but also reduce the weight of the mounting base 8 to a certain extent, which is beneficial to the lightweight design of the mounting base 8 .

[0110] Example 2

[0111] The present application also provides a winding machine, such as Figure 7 As shown, the winding machine includes a material preparation device 100, which has the same structure as any of the material preparation devices 100 in the above embodiments and can bring the same or similar beneficial effects. For details, please refer to the description in the above embodiments, and this embodiment will not be repeated here.

[0112] In the present application, since the preparation device 100 can complete the preparation of new tape by driving a driving member 41, the present application can reduce the number of driving members 41, thereby reducing manufacturing costs. At the same time, since it is easier to control one driving member 41 for driving, the control difficulty can also be reduced.

[0113] Furthermore, the first unwinding shaft 1 and the second unwinding shaft 2 are both used to install the material roll 3 for unwinding the tape. The winding machine also includes a gluing device, which is used to stick the tape pulled by the pulling component 7 on the base material of the battery cell.

[0114] With such arrangement, the adhesive tape sticking device can automatically stick the adhesive tape pulled by the pulling assembly 7 onto the base material of the battery cell, thereby reducing the time and labor intensity of manual operation and further improving production efficiency.

[0115] Regarding the structure of the gluing device, in the embodiment of the present application, the structural setting of the gluing device is relatively flexible. Specifically, it can be set according to actual needs, and the embodiment of the present application does not make specific limitations on this.

[0116] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present application, rather than to limit them. Although the present application has been described in detail with reference to the aforementioned embodiments, those skilled in the art should understand that they can still modify the technical solutions described in the aforementioned embodiments, or make equivalent replacements for some or all of the technical features therein. These modifications or replacements do not deviate the essence of the corresponding technical solutions from the scope of the technical solutions of the embodiments of the present application.
