Referring to FIG1 , an embodiment of the present invention provides a winding device, including a gluing device and a winding device. Referring to FIG1 and FIG2 , the gluing device is used to attach the second adhesive tape B to the passing pole piece material strip A. The gluing device is also used to cut the passing pole piece material strip A, and attach the first adhesive tape C to the two cut ends a formed by cutting the pole piece material strip A, so as to avoid the burrs of the cut ends a being exposed.

The pole piece strip A attached with the second tape B and the first tape C enters the winding device, which winds the pole piece strip A to form the battery cell 100. The pole piece strip A is then cut between the two cut ends a of the pole piece strip A (at this time, the two cut ends a of the pole piece strip A are still wrapped by the first tape C), so that the battery cell 100 is separated from the upstream pole piece strip A. The battery cell 100 is flattened in the subsequent process. The second adhesive tape B is located at the corner F of the innermost circle of the electrode strip A of the battery cell 100, so that the second adhesive tape B is used to protect the corner F of the innermost circle of the electrode strip A of the battery cell 100, avoiding wrinkles or cracks on the electrode strip A at the corner F; and the cut ends a of the innermost and outermost circles of the electrode strip A of the battery cell 100 are wrapped by the first adhesive tape C, so as to avoid the burrs of the cut ends a from being exposed, thereby greatly improving the safety of the battery cell 100.

It is understandable that, referring to FIG2 , the winding device winds four layers of tapes, including a layer of diaphragm D, the above-mentioned electrode tape A, another layer of diaphragm D and the electrode E, to form the battery cell 100. Of course, in other embodiments, the battery cell 100 may also include other tapes, which are not limited here.

As shown in FIG3 , in an embodiment of the present application, the gluing device includes a first clamping assembly 10, a second clamping assembly 20, a cutting assembly 30 and a first gluing assembly 40. The first clamping assembly 10 and the second clamping assembly 20 are arranged at intervals along the first direction X1, and are used for the pole piece strip A to pass through in sequence. The first clamping assembly 10 and the second clamping assembly 20 can both controllably clamp or release the pole piece strip A passing through. In other words, the pole piece strip A is conveyed along the first direction X1 and passes through the first clamping assembly 10 and the second clamping assembly 20 in sequence. The cutting assembly 30 can be controlled to move in or out between the first clamping assembly 10 and the second clamping assembly 20 along the second direction X2 to cut off the pole piece strip A passing between the first clamping assembly 10 and the second clamping assembly 20, and the pole piece strip A is cut to form two cut ends a. It should be noted that, for the convenience of description, the position where the cutting assembly 30 enters between the first clamping assembly 10 and the second clamping assembly 20 along the second direction X2 is named the first gluing position b1.

The first adhesive component 40 has an adsorption end for adsorbing the first adhesive tape C. The adsorption end of the first adhesive component 40 is opposite to the two cut ends a of the pole piece tape A in the third direction X3. The adsorption end of the first adhesive component 40 can be controlled to approach or move away from the two cut ends a of the pole piece tape A along the third direction X3 to adhere the first adhesive tape C to the two cut ends a of the pole piece tape A. The above-mentioned first direction X1, second direction X2 and third direction X3 intersect each other. Preferably, the first direction X1, second direction X2 and third direction X3 are perpendicular to each other. In actual use, the first direction X1 is the conveying direction of the pole piece tape A (that is, the longitudinal direction of the pole piece tape A), the second direction X2 is the width direction of the pole piece tape A, and the third direction X3 is the direction perpendicular to the pole piece tape A.

When the above-mentioned gluing device is actually used, first, the first clamping component 10 and the second clamping component 20 both clamp the pole piece strip A passing through. Then, the cutting component 30 moves along the second direction X2 until it enters the first gluing position b1 between the first clamping component 10 and the second clamping component 20. At this time, the cutting component 30 cuts off the pole piece strip A passing through the first gluing position b1, and two cut ends a are formed at the place where the pole piece strip A is cut. Then, the cutting component 30 moves in the opposite direction along the second direction X2 until it exits between the first clamping component 10 and the second clamping component 20, thereby avoiding the cutting component 30 from interfering with the subsequent gluing action of the first gluing component 40 between the first clamping component 10 and the second clamping component 20. Then, the adsorption end of the first adhesive component 40 moves along the third direction X3 toward the cut end a of the pole piece strip A, until the adsorption end of the first adhesive component 40 sticks the first tape C to the two cut ends a of the pole piece strip A, so that the two cut ends a of the pole piece strip A are reconnected through the first tape C, that is, the two cut ends a of the pole piece strip A are wrapped by the first tape C. Then, the adsorption end of the first adhesive component 40 stops adsorbing the first tape C, and moves away from the two cut ends a of the pole piece strip A along the third direction X3. Finally, the first clamping component 10 and the second clamping component 20 release the pole piece strip A, so that the pole piece strip A continues to be transported downstream to the winding device. The winding device winds the pole piece strip A with the first tape C attached to form the battery cell 100, and then cuts it at the position between the two cut ends a of the pole piece strip A, so that the battery cell 100 is separated from the pole piece strip A upstream thereof. At this time, the cut ends a of the electrode strips A at the innermost and outermost circles of the battery cell 100 are still wrapped by the first adhesive tape C, thereby greatly improving the safety of the battery cell 100 .

In this way, the gluing device of the present application sets the cutting component 30 to be able to move along the second direction X2 to enter or exit the first gluing position b1 between the first clamping component 10 and the second clamping component 20. When the cutting component 30 moves along the second direction X2 to enter the first gluing position b1, it can cut off the pole piece strip A passing through the first gluing position b1. When the cutting component 30 moves along the second direction X2 to exit the first gluing position b1, it can avoid the subsequent gluing action of the first gluing component 40 at the first gluing position b1. Therefore, compared with the prior art in which the cutting component is controlled to avoid along the first direction X1 to approach the first clamping component 10, the avoidance action of the cutting component 30 of the present application does not need to occupy the space between the first clamping component 10 and the second clamping component 20, thereby overcoming the problem of greater difficulty in spatial layout due to the small distance between the position where the second tape B is attached to the pole piece strip A and the position where the first tape C is attached.

Specifically in the embodiment, the gluing device also includes a mounting plate 90, and the first clamping component 10, the second clamping component 20, the cutting component 30 and the first gluing component 40 are all arranged on the mounting plate 90, so as to realize the integrated installation of various components, which is beneficial to improve space utilization.

Please refer to Figures 4 and 5. Specifically in the embodiment, the cutting assembly 30 includes a transfer seat 31, a first cutter 32 and a second cutter 33. The transfer seat 31 is movably connected to the mounting plate 90 along the second direction X2. The first cutter 32 and the second cutter 33 are arranged on the transfer seat 31 relative to each other in the third direction X3, and can be controlled to approach or move away from each other along the third direction X3. When the transfer seat 31 moves into the first gluing position b1 along the second direction X2, the pole piece strip A passing through the first gluing position b1 can enter between the first cutter 32 and the second cutter 33. In this way, when it is necessary to cut the pole piece strip A, the transfer seat 31 is controlled to move along the second direction X2 into the first gluing position b1 located between the first clamping assembly 10 and the second clamping assembly 20. At this time, the pole piece strip A passing through the first gluing position b1 enters between the first cutter 32 and the second cutter 33. Then, the first cutter 32 and the second cutter 33 are controlled to approach each other first and then move away from each other, so as to cut the pole piece strip A between the first cutter 32 and the second cutter 33. Then, the transfer carrier 31 is controlled to move along the second direction X2 to exit the first gluing position b1 between the first clamping assembly 10 and the second clamping assembly 20, so as to avoid the subsequent gluing action of the first gluing assembly 40 at the first gluing position b1.

Furthermore, the transfer seat 31 has a notch 317. When the transfer seat 31 moves along the second direction X2 to enter the first gluing position b1, the pole piece strip A passing through the first gluing position b1 passes through the notch 317 and enters between the first cutter 32 and the second cutter 33. In this way, the notch 317 on the transfer seat 31 prevents the transfer seat 31 from blocking the pole piece strip A from entering the space between the first cutter 32 and the second cutter 33.

Optionally, the transfer seat 31 includes a first side plate 311, a second side plate 315 and a third side plate 313. The first side plate 311 and the second side plate 315 are arranged at intervals along the third direction X3, and the third side plate 313 is fixedly connected between the first side plate 311 and the second side plate 315, and is located at the same end of the first side plate 311 and the second side plate 315 in the second direction X2. The above-mentioned notch 317 is formed between an end of the first side plate 311 away from the third side plate 313 and an end of the second side plate 315 away from the third side plate 313. The first cutter 32 is arranged on the side of the first side plate 311 facing the second side plate 315, and the second cutter 33 is arranged on the side of the second side plate 315 facing the first side plate 311.

Furthermore, the cutting assembly 30 further includes a first cutting drive member 34 and a first pressing plate 35. The first cutting drive member 34 is mounted on the first side plate 311 of the transfer seat 31, and the first pressing plate 35 is movably connected to the side of the first side plate 311 toward the second side plate 315 along the third direction X3. The driving end of the first cutting drive member 34 is connected to the first pressing plate 35 so that the first cutting drive member 34 can drive the first pressing plate 35 to move along the third direction X3. The first cutter 32 is mounted on the first pressing plate 35 to move along the third direction X3 with the first pressing plate 35.

The cutting assembly 30 also includes a moving seat 36, a second pressing plate 37, an elastic member 38 and a second cutting drive member 39. The second cutting drive member 39 is mounted on the second side plate 315 of the transfer seat 31, and the moving seat 36 is movably connected to the second side plate 315 along the third direction X3 toward the side of the first side plate 311. The driving end of the second cutting drive member 39 is connected to the moving seat 36 so that the second cutting drive member 39 can drive the moving seat 36 to move along the third direction X3. The second cutter 33 is mounted on the moving seat 36 to follow the moving seat 36 to approach or move away from the first cutter 32 along the third direction X3. The second pressing plate 37 is movably connected to the side of the moving seat 36 toward the first side plate 311 along the third direction X3. The elastic member 38 abuts between the moving seat 36 and the second pressing plate 37 to provide a preload force that allows the second pressing plate 37 to have a movement tendency close to the first pressing plate 35.

In this way, when the pole piece material strip A passing through the first gluing position b1 enters the space between the first cutter 32 and the second cutter 33, the first cutting drive member 34 drives the first pressing plate 35 to move toward the second pressing plate 37, thereby driving the first cutter 32 to move toward the second cutter 33; at the same time, the second cutting drive member 39 drives the moving seat 36 to move toward the first pressing plate 35, thereby driving the second pressing plate 37 to move toward the first pressing plate 35, and driving the second cutter 33 to move toward the first cutter 32. In the process of the first pressing plate 35 and the moving seat 36 approaching each other, the first pressing plate 35 and the second pressing plate 37 first press the pole piece material strip A passing by. As the moving seat 36 continues to move, the elastic member 38 is further compressed, and the first cutter 32 and the second cutter 33 continue to approach each other until the first cutter 32 and the second cutter 33 cut the pole piece material strip A passing by. Finally, the first cutting drive member 34 drives the first pressing plate 35 to move away from the second pressing plate 37, and the second cutting drive member 39 drives the movable seat 36 to move away from the first pressing plate 35 until returning to the initial position. Optionally, the first cutting drive member 34 and the second cutting drive member 39 can be cylinders, and the elastic member 38 can be a spring.

Optionally, the first pressing plate 35 may be installed on the first side plate 311 of the transfer base 31 via a first guide rod 391 , so that the first guiding rod 391 is used to guide the movement of the first pressing plate 35 relative to the first side plate 311 along the third direction X3 .

The movable seat 36 can be installed on the second side plate 315 of the transfer seat 31 through the second guide rod 392, so that the second guide rod 392 is used to guide the movement of the movable seat 36 relative to the second side plate 315 along the third direction X3.

The second pressing plate 37 can be installed on the moving seat 36 via the third guide rod 393 , so that the third guide rod 393 is used to guide the movement of the second pressing plate 37 relative to the moving seat 36 along the third direction X3 .

Specifically in the embodiment, the cutting assembly 30 further includes a translation drive member 13 mounted on the mounting plate 90. The driving end of the translation drive member 13 is connected to the transfer seat 31, so that the translation drive member 13 can drive the transfer seat 31 to move along the second direction X2. It should be noted that the translation drive member 13 can adopt a linear drive module, such as a ball screw module, an electric cylinder module or a cylinder, as long as it can drive the cutting assembly 30 to move along the second direction X2 to complete the cutting and avoidance actions, and is not limited here.

It should be noted that the cutting assembly 30 is not limited to the above structure. In other embodiments, the cutting assembly 30 may also adopt other cutting structures, such as a scissor-type cutting structure, as long as it can cut the electrode strip A when moving along the second direction X2 into the first gluing position b1, which is not limited here.

Please refer to Figures 3 and 6. In the embodiment of the present application, the first clamping assembly 10 includes a mounting seat 12 disposed on the mounting plate 90 and two clamping portions 11 disposed on the mounting seat 12 at intervals along the third direction X3. The two clamping portions 11 can be controlled to move closer to or farther from each other to clamp or loosen the pole piece strip A passing between the two clamping portions 11. In this way, when the pole piece strip A needs to be clamped, the two clamping portions 11 are controlled to move closer to each other along the third direction X3 until the two clamping portions 11 clamp the pole piece strip A between them.

Furthermore, each clamping portion 11 includes a clamping block 110 and a support plate 112. The clamping block 110 is movably connected to the mounting seat 12 along the third direction X3, and the support plate 112 is fixedly connected to the clamping block 110. The support plate 112 extends longitudinally from the clamping block 110 to the first gluing position b1. In this way, when it is necessary to clamp the pole piece strip A, the two clamping blocks 110 approach each other along the first direction X1 until the pole piece strip A is clamped. At this time, the pole piece strip A located between the clamping block 110 and the first gluing position b1 is supported and fixed between the two support plates 112, so that the corresponding cut end a formed after the pole piece strip A is cut does not produce a large droop, thereby facilitating the first gluing assembly 40 to stick the first tape C on the two cut ends a.

Furthermore, the third direction X3 is the up-down direction, and the length dimension of the support plate 112 located below the pole piece strip A in the first direction X1 is greater than the length dimension of the support plate 112 located above the pole piece strip A in the first direction X1. In this way, the support plate 112 located below the pole piece strip A is lengthened, so that the support plate 112 can support a longer pole piece strip A, further ensuring that the corresponding cut end a of the pole piece strip A does not sag significantly.

Specifically in the embodiment, at least one of the first clamping assembly 10 and the second clamping assembly 20 can be controlled to move closer to or away from the other. Preferably, the mounting seat 12 of the first clamping assembly 10 can be controlled to move closer to or away from the second clamping assembly 20 along the first direction X1. The second clamping assembly 20 is fixedly mounted on the mounting plate 90. In this way, when it is necessary to apply the first tape C, first, the first clamping assembly 10 and the second clamping assembly 20 both clamp the pole piece strip A passing through. After the cutting assembly 30 cuts the pole piece strip A, the mounting seat 12 of the first clamping assembly 10 moves away from the second clamping assembly 20 along the first direction X1, thereby driving the two cut ends a of the pole piece strip A to separate from each other by a certain distance. After the first adhesive assembly 40 sticks the first tape C to the two cut ends a of the pole piece strip A, the first clamping assembly 10 and the second clamping assembly 20 both release the pole piece strip A. Then, the mounting seat 12 of the first clamping assembly 10 moves a certain distance along the first direction X1 to approach the second clamping assembly 20 to prepare for the next clamping of the pole piece strip.

Optionally, the mounting seat 12 is mounted on the mounting plate 90 via a guide structure such as a slide rail and a slider, so that the guide structure is used to guide the movement of the mounting seat 12 relative to the mounting plate 90 along the first direction X1.

Specifically in the embodiment, the first clamping assembly 10 further includes a translation driver 13 and two clamping drivers 14. The translation driver 13 is mounted on the mounting plate 90 and connected to the mounting seat 12, so that the translation driver 13 can drive the mounting seat 12 to move relative to the mounting plate 90 along the first direction X1. The two clamping drivers 14 are both mounted on the mounting seat 12 and are respectively connected to the two clamping blocks 110, so that the two clamping drivers 14 respectively drive the two clamping blocks 110 to move closer to or away from each other, thereby clamping or loosening the pole piece strip A.

It should be noted that the structure of the second clamping assembly 20 is similar to that of the first clamping assembly 10 , so it will not be described in detail here.

Please continue to refer to FIG. 3. In the embodiment of the present application, the gluing device further includes a first glue preparation component 50 for providing the first adhesive tape C. The first gluing component 40 can be moved to a first position d1 and a second position d2 along the first direction X1. When the first gluing component 40 moves to the first position d1 along the first direction X1, the adsorption end of the first gluing component 40 is opposite to the first adhesive tape C provided by the first glue preparation component 50 in the third direction X3, so that when the adsorption end of the first gluing component 40 moves along the third direction X3, it can absorb the first adhesive tape C provided by the first glue preparation component 50. When the first gluing component 40 moves to the second position d2 along the first direction X1, the adsorption end of the first gluing component 40 is opposite to the two cut ends a of the pole piece material strip A in the third direction X3, so that when the adsorption end of the first gluing component 40 moves along the third direction X3, it can stick the adsorbed first adhesive tape C to the two cut ends a of the pole piece material strip A.

Specifically in the embodiment, the first adhesive component 40 includes a first moving seat, a first driving structure 41 (see FIG. 10 ) and a first adsorption plate 42 (see FIG. 10 ). The first moving seat is movably connected to the mounting plate 90 along the first direction X1. The first driving structure 41 is mounted on the first moving seat, and the first adsorption plate 42 is mounted on the driving end of the first driving structure 41, so that the first driving structure 41 can drive the first adsorption plate 42 to move along the third direction X3. The first adsorption plate 42 serves as the adsorption end of the above-mentioned first adhesive component 40, and can controllably adsorb or release the first adhesive tape C.

In this way, when there is no first adhesive tape C on the first adsorption plate 42, the first moving seat is controlled to move relative to the mounting plate 90 along the first direction X1 until the first adsorption plate 42 reaches the first position d1, so that the first adsorption plate 42 and the first adhesive tape C provided by the first adhesive preparation component 50 are opposite to each other in the third direction X3. At this time, the first driving structure 41 drives the first adsorption plate 42 to approach the first adhesive preparation component 50 along the third direction X3 until the first adsorption plate 42 contacts the first adhesive tape C provided on the first adhesive preparation component 50. Then, the first adsorption plate 42 adsorbs the first adhesive tape C. Then, the first driving structure 41 drives the first adsorption plate 42 to move away from the first adhesive preparation component 50 along the third direction X3 until it returns to the initial position.

When it is necessary to stick the first adhesive tape C on the first adsorption plate 42 to the pole piece material strip A, the first moving seat is controlled to move relative to the mounting plate 90 along the first direction X1 until the first adsorption plate 42 reaches the second position d2, so that the first adsorption plate 42 and the two cut ends a of the pole piece material strip A (i.e., the first gluing position b1) are opposite in the third direction X3. Then, the first driving structure 41 drives the first adsorption plate 42 to approach the pole piece material strip A along the third direction X3 until the first adhesive tape C is stuck to the two cut ends a of the pole piece material strip A. Then, the first adsorption plate 42 stops adsorbing the first adhesive tape C, and under the driving action of the first driving structure 41, moves away from the pole piece material strip A along the third direction X3 until it returns to the initial position.

Furthermore, the first driving structure 41 can also drive the first adsorption plate 42 to move along the second direction X2, so as to adjust the position of the first adsorption plate 42 in the second direction X2. In this way, the first adsorption plate 42 is driven by the first driving structure 41 to adjust its position along the second direction X2, ensuring that the first adsorption plate 42 can accurately absorb the first adhesive tape C provided by the first adhesive preparation component 50 during adhesive preparation, and the first adsorption plate 42 can accurately adhere the first adhesive tape C to the two cut ends a of the pole piece strip A during adhesive application.

It should be noted that the first driving structure 41 can adopt relatively mature existing technologies, as long as it can drive the first adsorption plate 42 to move along the second direction X2 and the third direction X3, and is not limited here.

Please refer to FIG. 3 again. In the embodiment of the present application, the number of the first glue assembly 40 and the first glue preparation assembly 50 are both set to two. One of the first glue assemblies 40 and the first glue preparation assembly 50 is a first group, and the other first glue assembly 40 and the other first glue preparation assembly 50 are a second group. The first group is arranged on one side of the pole piece strip A in the third direction X3, and the second group is arranged on the other side of the pole piece strip A in the third direction X3. In this way, the first glue preparation assembly 50 in the first group is used to provide the first tape C for the adsorption end of the first glue assembly 40 in the first group; the first glue preparation assembly 50 in the second group is used to provide the first tape C for the adsorption end of the first glue assembly 40 in the second group. The first adhesive tape C is pasted from one side of the pole piece strip A to the two cut ends a using the adsorption end of the first adhesive component 40 in the first group; at the same time, the first adhesive tape C is pasted from the other side of the pole piece strip A to the two cut ends a using the adsorption end of the first adhesive component 40 in the second group, thereby ensuring that the two cut ends a of the pole piece strip A are completely wrapped.

In an embodiment of the present application, the gluing device further includes a second gluing component 60, and the second gluing component 60 has an adsorption end for adsorbing the second adhesive tape B, and the adsorption end of the second gluing component 60 is opposite to the pole piece material strip A passing through in the third direction X3. For the convenience of description, the gluing position of the adsorption end of the second gluing component 60 is named as the second gluing position b2. The second gluing position b2 is located on the side of the first clamping component 10 away from the second clamping component 20. The adsorption end of the second gluing component 60 can be controlled to approach or move away from the second gluing position b2 along the third direction X3, so as to adhere the second adhesive tape B to the pole piece material strip A passing through the second gluing position b2. In this way, after the winding device winds the pole piece strip A with the second adhesive tape B attached thereto into the battery cell 100, the second adhesive tape B is located at the corner F of the pole piece strip A of the innermost circle of the battery cell 100, thereby protecting the corner F of the pole piece strip A of the innermost circle of the battery cell 100, avoiding wrinkles or cracks on the surface of the pole piece strip A at the corner F, and improving the safety of the battery cell 100.

Specifically in the embodiment, the glue sticking device also includes a third glue sticking component 70, and the third glue sticking component 70, the second glue sticking component 60 and the first glue sticking component 40 are sequentially arranged on the mounting plate 90 at intervals along the first direction X1. The third glue sticking component 70 has an adsorption end for adsorbing the second adhesive tape B. The adsorption end of the third glue sticking component 70 is opposite to the pole piece material strip A passing through in the third direction X3. For the convenience of description, the glue sticking position of the adsorption end of the third glue sticking component 70 is named as the third glue sticking position b3. The third glue sticking position b3 is located on the side of the second glue sticking position b2 away from the first clamping component 10. The adsorption end of the third glue sticking component 70 can be controlled to approach or move away from the third glue sticking position b3 along the third direction X3, so as to stick the second adhesive tape B to the pole piece material strip A passing through the third glue sticking position b3.

In this way, the second glue component 60 and the third glue component 70 are used to stick two second tapes B onto the pole piece strip A passing through the second glue position b2 and the third glue position b3, so that after the section of pole piece strip A is wound to form the battery cell 100, the two second tapes B stuck by the second glue component 60 and the third glue component 70 are respectively located at the two corners F of the pole piece strip A of the innermost circle of the battery cell 100, thereby protecting the two corners F of the pole piece strip A of the innermost circle of the battery cell 100, which is beneficial to improving the safety of the battery cell 100.

Specifically in the embodiment, the glue application device further includes a second glue preparation component 80, which is used to provide a second adhesive tape B to the second glue application component 60 and the third glue application component 70. The second glue application component 60 and the third glue application component 70 can move relative to the second glue preparation component 80 in the first direction X1 to a glue preparation state and a glue application state.

When in the glue preparation state, the suction end of the second glue component 60 or the third glue component 70 is opposite to the second adhesive tape B provided by the second glue preparation component 80 in the third direction X3, so that when the suction end of the second glue component 60 or the third glue component 70 moves along the third direction X3, it can absorb the second adhesive tape B provided by the second glue preparation component 80. When in the glue application state, the suction end of the second glue component 60 is opposite to the second glue application position b2 in the third direction X3, so that when the suction end of the second glue component 60 moves along the third direction X3, it can stick the sucked second adhesive tape B to the pole piece material strip A passing through the second glue application position b2; at the same time, the suction end of the third glue component 70 is opposite to the third glue application position b3 in the third direction X3, so that when the suction end of the third glue component 70 moves along the third direction X3, it can stick the sucked second adhesive tape B to the pole piece material strip A passing through the third glue application position b3.

Thus, in actual use, when there is no second adhesive tape B on the second adhesive component 60, the second adhesive component 60 and the second adhesive preparation component 80 are controlled to move relative to each other in the first direction X1 until the adsorption end of the second adhesive component 60 and the second adhesive tape B provided by the second adhesive preparation component 80 are opposite to each other in the third direction X3. At this time, the adsorption end of the second adhesive component 60 first approaches and then moves away from the second adhesive preparation component 80 along the third direction X3, and absorbs the second adhesive tape B provided by the second adhesive preparation component 80. Similarly, when there is no second adhesive tape B on the third adhesive component 70, the third adhesive component 70 and the second adhesive preparation component 80 are controlled to move relative to each other in the first direction X1 until the adsorption end of the third adhesive component 70 and the second adhesive tape B provided by the second adhesive preparation component 80 are opposite to each other in the third direction X3. At this time, the adsorption end of the third adhesive component 70 first approaches and then moves away from the second adhesive preparation component 80 along the third direction X3, and absorbs the second adhesive tape B provided by the second adhesive preparation component 80.

When it is necessary to attach the second adhesive tape B to the pole piece material strip A, the second adhesive component 60 and the third adhesive component 70 are controlled to move relative to the second adhesive component 80 in the first direction X1, until the adsorption ends of the second adhesive component 60 and the third adhesive component 70 are misaligned with the second adhesive component 80 in the third direction X3, and the adsorption end of the second adhesive component 60 is opposite to the second adhesive position b2 in the third direction X3, and the adsorption end of the third adhesive component 70 is opposite to the third adhesive position b3 in the third direction X3. At this time, the adsorption end of the second adhesive component 60 moves along the third direction X3 first close to and then away from the second adhesive position b2, and the adsorbed second adhesive tape B is attached to the pole piece material strip A passing through the second adhesive position b2, and the adsorption end of the third adhesive component 70 moves along the third direction X3 first close to and then away from the third adhesive position b3, and the adsorption second adhesive tape B is attached to the pole piece material strip A passing through the third adhesive position b3.

Thus, compared with the solution in the prior art that each glue assembly needs to be equipped with a standby glue assembly, in the present application, the second glue assembly 60 and the third glue assembly 70 are respectively moved relative to the second standby glue assembly 80 in the first direction X1 to achieve state switching, thereby achieving the second standby glue assembly 80 to provide the second adhesive tape B to the second glue assembly 60 and the third glue assembly 70 respectively, and also achieving the second standby glue assembly 80 to avoid the glue action of the second glue assembly 60 and the third glue assembly 70 to the pole piece material strip A, thereby reducing the number of standby glue assemblies, simplifying the structure of the glue device, improving space utilization, and reducing the difficulty of spatial layout of each component.

In some embodiments, the second adhesive component 60 is movably connected to the mounting plate 90 along the first direction X1, and the third adhesive component 70 is also movably connected to the mounting plate 90 along the first direction X1. The second adhesive preparation component 80 is fixedly mounted on the mounting plate 90. That is, the second adhesive component 60 is movable relative to the mounting plate 90 along the first direction X1, the third adhesive component 70 is also movable relative to the mounting plate 90 along the first direction X1, and the second adhesive preparation component 80 is fixed relative to the mounting plate 90, so that the second adhesive component 60 and the third adhesive component 70 can move relative to the second adhesive preparation component 80 along the first direction X1, thereby realizing switching between the adhesive preparation state and the adhesive state.

Of course, the switching between the glue preparation state and the glue application state is not limited to the method of using the second glue application component 60 and the third glue application component 70 to move along the first direction X1 and the second glue preparation component 80 to be fixed. In other embodiments, the second glue application component 60 and the third glue application component 70 are both fixedly mounted on the mounting plate 90, and the second glue preparation component 80 is movably connected to the mounting plate 90 along the first direction X1. In this way, by moving the second glue preparation component 80 relative to the mounting plate 90 along the first direction X1, the second glue application component 60 and the third glue application component 70 and the second glue preparation component 80 generate relative movement in the first direction X1, thereby realizing the switching between the glue preparation state and the glue application state.

For ease of understanding, this article takes the solution in which the second adhesive component 60 and the third adhesive component 70 are movable relative to the mounting plate 90 along the first direction X1 and the second adhesive component 80 is fixed relative to the mounting plate 90 as an example for explanation.

Please refer to FIGS. 7 to 9 , specifically in the embodiment, the glue sticking device further includes a second moving seat 73 and a driving unit 93 (see FIG. 8 ). The second moving seat 73 is arranged on the mounting plate 90, and the driving unit 93 is also mounted on the mounting plate 90 and connected to the second moving seat 73, so that the driving unit 93 can drive the second moving seat 73 to move relative to the mounting plate 90 along the first direction X1. The second glue sticking assembly 60 and the third glue sticking assembly 70 are both mounted on the second moving seat 73 to move relative to the mounting plate 90 along the first direction X1 with the second moving seat 73, so as to realize the second glue sticking assembly 60 and the third glue sticking assembly 70 to move relative to the second glue preparation assembly 80 along the first direction X1, thereby realizing the switching between the glue preparation state and the glue sticking state.

In this way, when there is no second adhesive tape B on the second adhesive component 60, the driving unit 93 drives the second moving seat 73 to move along the first direction X1 until the second adhesive component 60 follows the second moving seat 73 to move to the second adhesive preparation component 80, so that the suction end of the second adhesive component 60 and the second adhesive tape B provided by the second adhesive preparation component 80 are opposite to each other in the third direction X3. At this time, the suction end of the second adhesive component 60 absorbs the second adhesive tape B provided by the second adhesive preparation component 80 along the third direction X3.

When there is no second adhesive tape B on the third adhesive component 70, the driving unit 93 drives the second moving seat 73 to move along the first direction X1 until the third adhesive component 70 follows the second moving seat 73 to move to the second adhesive preparation component 80, so that the suction end of the third adhesive component 70 and the second adhesive tape B provided by the second adhesive preparation component 80 are opposite to each other in the third direction X3. At this time, the suction end of the third adhesive component 70 absorbs the second adhesive tape B provided by the second adhesive preparation component 80 along the third direction X3.

When it is necessary to glue the pole piece strip A, the driving unit 93 drives the second moving seat 73 to move along the first direction X1 (at this time, the second glue component 60 and the third glue component 70 move along the first direction X1 with the second moving seat 73) until the adsorption ends of the second glue component 60 and the third glue component 70 are misaligned with the second glue preparation component 80 in the third direction X3, and the adsorption end of the second glue component 60 is opposite to the second glue position b2 in the third direction X3. At this time, the adsorption end of the second glue component 60 adheres the second tape B to the pole piece strip A passing through the second glue position b2 along the third direction X3; at the same time, the adsorption end of the third glue component 70 is opposite to the third glue position b3 in the third direction X3. At this time, the adsorption end of the third glue component 70 adheres the second tape B to the pole piece strip A passing through the third glue position b3 along the third direction X3.

It should be noted that the driving unit 93 may be a linear module, such as a screw module, an electric cylinder, etc., as long as it can drive the second moving seat 73 to move relative to the mounting plate 90 along the first direction X1, and no limitation is made here.

Optionally, a slide rail is provided on the mounting plate 90, and the slide rail extends longitudinally along the first direction X1. A slider is provided on the second motion seat 73, and the slider is slidably matched with the slide rail. In this way, the movement of the slider along the slide rail guides the movement of the second motion seat 73 along the first direction X1.

Further, the mounting plate 90 includes a front side, a back side opposite to the front side, and a strip-shaped avoidance groove 91 running through the front side and the back side, and the strip-shaped avoidance groove 91 extends longitudinally along the first direction X1. The second adhesive component 60, the third adhesive component 70, the second motion seat 73, and the second adhesive component 80 are all arranged on the front side of the mounting plate 90, and the driving unit 93 is arranged on the back side of the mounting plate 90. The driving end of the driving unit 93 passes through the strip-shaped avoidance groove 91 and is connected to the second motion seat 73, so that the driving unit 93 can drive the second motion seat 73 to move along the first direction X1. In this way, the driving unit 93 is arranged on the back side of the mounting plate 90, thereby saving space on the front side of the mounting plate 90, and reducing the difficulty of spatial arrangement of the second adhesive component 60, the third adhesive component 70, the second motion seat 73, and the second adhesive component 80. It can be understood that the first adhesive component 40, the first adhesive component 50, the first clamping component 10, and the second clamping component 20 are also arranged on the front side of the mounting plate 90.

Specifically in the embodiment, the number of the second adhesive assembly 60, the third adhesive assembly 70, the second moving seat 73 and the second adhesive assembly 80 are all two. One second adhesive assembly 60, one third adhesive assembly 70, one second moving seat 73 and one second adhesive assembly 80 are the first group, and another second adhesive assembly 60, another third adhesive assembly 70, another second moving seat 73 and another second adhesive assembly 80 are the second group. The first group is arranged on one side of the pole piece strip A in the third direction X3, and the second group is arranged on the other side of the pole piece strip A in the third direction X3.

In this way, the second adhesive tape B is adhered to the pole piece strip A passing through the second adhesive tape position b2 from both sides of the pole piece strip A using the second adhesive tape component 60 in the first group and the second adhesive tape component 60 in the second group; the second adhesive tape B is adhered to the pole piece strip A passing through the third adhesive tape position b3 from both sides of the pole piece strip A using the third adhesive tape component 70 in the first group and the third adhesive tape component 70 in the second group, thereby ensuring that the second adhesive tape B is adhered to both side surfaces of each corner F of the pole piece strip A of the innermost circle of the battery cell 100, thereby further improving the safety of the battery cell 100.

Further, the second moving seats 73 in the first group and the second moving seats 73 in the second group are fixedly connected by a connecting frame 94 (see FIG. 8 ), so that the two second moving seats 73 can move synchronously. In this way, when the driving unit 93 drives one of the second moving seats 73 to move along the first direction X1, the other second moving seat 73 also moves synchronously along the first direction X1, so that the two second glue sticking assemblies 60 and the two third glue sticking assemblies 70 move synchronously along the first direction X1, thereby realizing the switching between the glue preparation state and the glue sticking state, so as to complete the glue preparation and glue sticking.

It should be noted that using one driving unit 93 to drive the two second moving seats 73 to move is beneficial to simplifying the structure of the glue sticking device and reducing the cost of the glue sticking device.

Furthermore, two strip-shaped avoidance grooves 91 are provided on the mounting plate 90, and the two strip-shaped avoidance grooves 91 are respectively opposite to the two second motion seats 73. The connecting frame 94 is located on the back of the mounting plate 90, and one end of the connecting frame 94 passes through one of the strip-shaped avoidance grooves 91 and is fixedly connected to the corresponding second motion seat 73; the other end of the connecting frame 94 passes through another strip-shaped avoidance groove 91 and is fixedly connected to another corresponding second motion seat 73, thereby realizing the fixed connection of the two second motion seats 73. Moreover, when the driving unit 93 drives one of the second motion seats 73 to move along the first direction X1, the two second motion seats 73 and the connecting frame 94 connected between the two second motion seats 73 move together along the first direction X1, and in this process, the two strip-shaped avoidance grooves 91 play a role in avoiding the movement of the connecting frame 94 along the first direction X1.

In the embodiment of the present application, the second adhesive component 60 includes a second driving structure 61 and a second adsorption plate 62. The second driving structure 61 is mounted on the second moving seat 73, and the second adsorption plate 62 is mounted at the driving end of the second driving structure 61, so that the second driving structure 61 can drive the second adsorption plate 62 to move along the third direction X3. The second adsorption plate 62 serves as the adsorption end of the second adhesive component 60, and can controllably adsorb or release the second adhesive tape B.

In this way, when there is no second adhesive tape B on the second adsorption plate 62, the driving unit 93 drives the second moving seat 73 to move along the first direction X1 until the second adsorption plate 62 and the second adhesive tape B provided by the second adhesive preparation component 80 are opposite to each other in the third direction X3. At this time, the second driving structure 61 drives the second adsorption plate 62 to move close to the second adhesive preparation component 80 along the third direction X3 until the second adsorption plate 62 contacts the second adhesive tape B provided on the second adhesive preparation component 80. Then, the second adsorption plate 62 adsorbs the second adhesive tape B. Then, the second driving structure 61 drives the second adsorption plate 62 away from the second adhesive preparation component 80 along the third direction X3 until it returns to the initial position.

When it is necessary to stick the second adhesive tape B on the second adsorption plate 62 to the pole piece material strip A, the driving unit 93 drives the second moving seat 73 to move along the first direction X1 until the second adsorption plate 62 reaches a position opposite to the second gluing position b2 in the third direction X3. Then, the second driving structure 61 drives the second adsorption plate 62 to approach the pole piece material strip A passing through the second gluing position b2 along the third direction X3 until the second adsorption plate 62 sticks the second adhesive tape B to the pole piece material strip A passing through the second gluing position b2. Then, the second adsorption plate 62 releases the adsorption of the second adhesive tape B, and moves away from the pole piece material strip A along the third direction X3 under the driving action of the second driving structure 61 until it returns to the initial position.

Furthermore, the second driving structure 61 can also drive the second adsorption plate 62 to move along the second direction X2, so as to adjust the position of the second adsorption plate 62 in the second direction X2. In this way, the second adsorption plate 62 is driven by the second driving structure 61 to adjust its position along the second direction X2, ensuring that the second adsorption plate 62 can accurately absorb the second adhesive tape B on the second adhesive preparation component 80 during adhesive preparation, and the second adsorption plate 62 can accurately stick the second adhesive tape B to the pole piece strip A passing through the second adhesive application position b2 during adhesive application.

It should be noted that the second driving structure 61 can adopt relatively mature existing technologies, as long as it can drive the second adsorption plate 62 to move along the second direction X2 and along the third direction X3, and no limitation is made here.

In the embodiment of the present application, the third adhesive component 70 includes a third driving structure 71 and a third adsorption plate 72. The third driving structure 71 is mounted on the second moving seat 73, and the third adsorption plate 72 is mounted at the driving end of the third driving structure 71, so that the third driving structure 71 can drive the third adsorption plate 72 to move along the third direction X3. The third adsorption plate 72 serves as the adsorption end of the third adhesive component 70, and can controllably adsorb or release the second adhesive tape B.

In this way, when there is no second adhesive tape B on the third adsorption plate 72, the driving unit 93 drives the second moving seat 73 to move along the first direction X1 until the third adsorption plate 72 and the second adhesive tape B provided by the second adhesive preparation component 80 are opposite to each other in the third direction X3. At this time, the third driving structure 71 drives the third adsorption plate 72 to approach the second adhesive preparation component 80 along the third direction X3 until the third adsorption plate 72 contacts the second adhesive tape B provided on the second adhesive preparation component 80. Then, the third adsorption plate 72 adsorbs the second adhesive tape B. Then, the third driving structure 71 drives the third adsorption plate 72 to move away from the second adhesive preparation component 80 along the third direction X3 until it returns to the initial position.

When it is necessary to stick the second adhesive tape B on the third adsorption plate 72 to the pole piece material strip A, the driving unit 93 drives the second moving seat 73 to move along the first direction X1 until the third adsorption plate 72 reaches a position opposite to the third gluing position b3 in the third direction X3. Then, the third driving structure 71 drives the third adsorption plate 72 to approach the pole piece material strip A passing through the third gluing position b3 along the third direction X3 until the second adhesive tape B is stuck to the pole piece material strip A passing through the third gluing position b3. Then, the third adsorption plate 72 releases the adsorption of the second adhesive tape B, and moves away from the pole piece material strip A along the third direction X3 under the driving action of the third driving structure 71 until it returns to the initial position.

Furthermore, the third driving structure 71 can also drive the third adsorption plate 72 to move along the second direction X2, so as to adjust the position of the third adsorption plate 72 in the second direction X2. In this way, the third adsorption plate 72 is driven by the third driving structure 71 to adjust its position along the second direction X2, ensuring that the third adsorption plate 72 can accurately absorb the second adhesive tape B on the second adhesive preparation component 80 during adhesive preparation, and the third adsorption plate 72 can accurately adhere the second adhesive tape B to the pole piece strip A passing through the third adhesive application position b3 during adhesive application.

It should be noted that the third driving structure 71 can adopt relatively mature existing technologies, as long as it can drive the third adsorption plate 72 to move along the second direction X2 and the third direction X3, and is not limited here.

Please refer to FIG. 10 . In the embodiment of the present application, in the first direction X1, the first driving structure 41 is located on the side of the first adsorption plate 42 away from the second adsorption plate 62, and the second driving structure 61 is located on the side of the second adsorption plate 62 away from the first adsorption plate 42. In this way, when the first adhesive component 40 adheres the first adhesive tape C to the two cut ends a of the pole piece material strip A, the first driving structure 41 will not interfere with the second adhesive component 60; when the second adhesive component 60 adheres the second adhesive tape B to the pole piece material strip A, the second driving structure 61 will not interfere with the first adhesive component 40, thereby improving space utilization and reducing the difficulty of spatial layout of various components.

Furthermore, in the first direction X1, the third driving structure 71 is located on the side of the third adsorption plate 72 away from the second adsorption plate 62, which is beneficial to improving space utilization and facilitating the spatial layout of the third driving structure 71 and the second driving structure 61.
