Description

Technical Field

[0001] The present application relates to the technical field of battery production and preparation, and in particular to a film rolling mechanism and a laminating machine. Background Art

[0002] In some lithium battery stacking processes, the positive electrode sheets, separators and negative electrode sheets need to be stacked, and then the positive electrode sheets, separators and negative electrode sheets are wound or stacked according to the process requirements to obtain a battery cell roll. After winding or stacking a battery cell roll, the separator needs to be cut so that the manufactured battery cell can be moved away. However, since the separator material is relatively soft, its free end is easily entangled on the guide assembly after being cut, resulting in the external film material traction mechanism being unable to traction the free end of the separator when stacking or winding the next battery cell, requiring manual intervention, which reduces the production efficiency of the battery cell. Utility Model Content

[0003] To this end, the present application provides a film rolling mechanism and a laminating machine to solve the above-mentioned technical problems.

The stacking machine includes a guide assembly, and the guide assembly is provided with a first gap for allowing a film material to pass through so as to guide the film material; the film-stretching mechanism includes a clamping member, and when the film material needs to be cut, the clamping member is used to fix at least part of the film material from one side of the guide assembly close to the film material cutting position to the film material cutting position.

[0005] A second aspect of the present application provides a laminating machine, which includes the aforementioned film-stretching mechanism.

[0006] In the present application, the film-pulling mechanism includes a clamping member, and when the film material needs to be cut, the clamping member is used to fix at least part of the film material from the side of the guide assembly close to the film material cutting position to the film material cutting position, thereby preventing the free end of the film material from being wound around the guide assembly after the film material is cut. In the subsequent production and preparation process, the external film material traction mechanism does not require manual intervention when traction of the film material, thereby saving labor costs and improving the degree of production automation and production efficiency.

[0017] like Figure 1 and Figure 2 As shown, in some embodiments, the laminating machine 100 includes a guiding assembly 10 and a film-sliding mechanism 20 . The guiding assembly 10 is provided with a first gap 11 for allowing the film material 30 to pass through so as to guide the film material 30 .

[0018] In some embodiments, Figure 3 As shown, the guide assembly 10 includes two first guide rollers 110, which are arranged side by side at the same height position, and there is a first gap 11 between the two first guide rollers 110. The two first guide rollers 110 may not be rotatable. In other embodiments, at least one of the two first guide rollers 110 may be rotatable.

[0019] In some embodiments, Figure 2 and Figure 3 As shown, the film-sliding mechanism 20 is applied to the stacking machine 100, and the film-sliding mechanism 20 includes a clamping member 200. When the film material 30 needs to be cut, the clamping member 200 is used to fix at least part of the film material 30 from the side of the guide assembly 10 close to the film material cutting position A to the film material cutting position A.

[0020] In the present application, the film-pulling mechanism 20 includes a clamping member 200. When the film material 30 needs to be cut, the clamping member 200 is used to fix the guide component 10 close to the film material cutting position A to at least a portion of the film material 30 at the film material cutting position A, thereby preventing the free end 31 of the film material from being wound onto the guide component 10 after the film material 30 is cut. In the subsequent production and preparation process, the external film material pulling mechanism does not require manual intervention when pulling the film material 30, thereby saving labor costs and improving the degree of production automation and production efficiency.

[0021] The membrane material 30 may be, but is not limited to, a single-layer PE (polyethylene) membrane, a composite membrane of PP (polypropylene) + PE + PP, and the like.

[0022] In some embodiments, Figure 1 As shown, the laminating machine 100 further includes an unwinding mechanism 40 , and the unwinding mechanism 40 is used to pull out the rolled film material 30 .

[0023] In some embodiments, Figure 2 As shown, the unwinding mechanism 40 includes at least one group of unwinding rollers 41 and second guide rollers 42. A third gap 43 is provided between each group of unwinding rollers 41 and the second guide rollers 42. The third gap 43 is for the film material 30 to pass through. The unwinding rollers 41 are rotatable, and the second guide rollers 42 are not rotatable. The unwinding rollers 41 rotate and cooperate with the second guide rollers 42 to continuously pull out the rolled film material 30 through friction.

[0024] In some embodiments, Figure 1 As shown, the stacking machine 100 further includes a film material pulling mechanism 50 and a film material cutting mechanism 60 . The film material cutting mechanism 60 is used to cut the film material 30 , and the film material pulling mechanism 50 is used to pull the film material 30 extending from the guide assembly 10 to the battery cell stacking position.

[0025] In some embodiments, Figure 2 As shown, when the film material 30 needs to be cut, the film-sliding mechanism 20 is located at a preset position, and at the preset position, the film-sliding mechanism 20 is closer to the film-cutting position A than the guiding assembly 10 .

[0026] Therefore, it is more convenient for the film-sliding mechanism 20 to fix the guiding assembly 10 close to the film-cutting position A to at least a portion of the film 30 at the film-cutting position A.

[0027] In some embodiments, Figure 2 and Figure 3 As shown, the film-pulling mechanism 20 includes a clamping drive 22 , which is connected to a clamping member 200 . The clamping member 200 is provided with a second gap 21 , and the second gap 21 allows the film material 30 to pass therethrough. The clamping drive 22 drives the clamping member 200 to change the gap width of the second gap 21 .

[0028] The radial direction of the second gap 21 may be the thickness direction B of the film material.

[0029] Since the clamping driving member 22 drives the clamping member 200 to change the gap width of the second gap 21, when the film material 30 needs to be unwound, the clamping driving member 22 drives the clamping member 200 to increase the gap width of the second gap 21, so that the film material 30 can pass through the clamping member 200 without friction. Therefore, it can be avoided that the film material 30 is damaged or dust and foreign matter are increased due to friction between the film material 30 and the clamping member 200, which affects the quality of the battery cell.

[0030] In some embodiments, Figure 2 and Figure 3 As shown, the clamping member 200 includes a first film-smoothing plate 23 and a second film-smoothing plate 24 that are arranged opposite to each other. The first film-smoothing plate 23 and the second film-smoothing plate 24 are respectively connected to the clamping driving member 22. The clamping driving member 22 drives the first film-smoothing plate 23 and the second film-smoothing plate 24 to move toward each other, which can reduce the gap width of the second gap 21 and fix at least part of the film material 30. The clamping driving member 22 also drives the first film-smoothing plate 23 and the second film-smoothing plate 24 to move away from each other, which can increase the gap width of the second gap 21, so that the film material 30 passes through the second gap 21 without friction.

[0031] Thus, by fixing the guide assembly 10 from one side of the film material cutting position A to at least a portion of the film material 30 where the film material 30 is cut by clamping the first film-smoothing plate 23 and the second film-smoothing plate 24 relative to each other, a whole section of the film material 30 can be clamped. Compared with the method of clamping the opposite sides of the film material 30, the clamping area is larger and more stable, and the film material 30 is located between the two planes of the first film-smoothing plate 23 and the second film-smoothing plate 24, so the film material 30 will not be scratched.

[0032] The first film-smoothing plate 23 and the second film-smoothing plate 24 move toward each other to fix at least a portion of the film 30 of the guide assembly 10 close to the film-cutting position A to the film-cutting position A in a clamping manner.

[0033] In some embodiments, Figure 3 As shown, the first film stroking plate 23 includes a first sub-plate 2301 and a second sub-plate 2302, wherein the first sub-plate 2301 is connected to the clamping driving member 22, and the second sub-plate 2302 is connected to the first sub-plate 2301. The length of the second sub-plate 2302 is less than the length of the first sub-plate 2301, and the width of the second sub-plate 2302 is greater than the width of the first sub-plate 2301, wherein the length side of the second sub-plate 2302 is parallel to the width side of the film material 30.

[0034] Therefore, the first sub-plate 2301 mainly plays a connecting role, and the second sub-plate 2302 mainly plays a fixing role of the membrane material 30 .

[0035] In some embodiments, Figure 3As shown, the second film stroking plate 24 includes a third sub-plate 2401 and a fourth sub-plate 2402, the third sub-plate 2401 is connected to the clamping drive member 22, and the fourth sub-plate 2402 is connected to the third sub-plate 2401. The length of the fourth sub-plate 2402 is less than the length of the third sub-plate 2401, and the width of the fourth sub-plate 2402 is greater than the width of the third sub-plate 2401, wherein the length side of the fourth sub-plate 2402 is parallel to the width side of the film material 30.

[0036] Therefore, the third sub-plate 2401 mainly plays a connecting role, and the fourth sub-plate 2402 mainly plays a fixing role of the membrane material 30 .

[0037] In some embodiments, when the film-smoothing mechanism 20 is located at the preset position, the first film-smoothing plate 23 and the second film-smoothing plate 24 are closer to the film-cutting position A than the guide assembly 10 is closer to the film-cutting position A.

[0038] In some other embodiments, the clamping member 200 includes a first mechanical gripper (not labeled) and a second mechanical gripper (not labeled) arranged opposite to each other. When the film material 30 needs to be cut, the clamping driving member 22 drives the first mechanical gripper and the second mechanical gripper to respectively clamp the two opposite sides of the film material 30 from the side of the guide assembly 10 close to the film material cutting position A to the cutting position of the film material 30. When the film material 30 needs to be unwound, the clamping driving member 22 drives the first mechanical gripper and the second mechanical gripper to release the gripper, so that the film material 30 passes through the film-winding mechanism 20 without friction.

[0039] In some embodiments, Figure 3-Figure 5 As shown, the clamping driving member 22 includes a first mounting member 221, a second mounting member 222, a first elastic member 223 and a second elastic member 224. One end of the first film plate 23 and the second film plate 24 are respectively connected to the first mounting member 221. The other ends of the first film plate 23 and the second film plate 24 are respectively connected to the second mounting member 222. The first elastic member 223 and the second elastic member 224 are used to provide elastic force to push the first film plate 23 close to the second film plate 24 to reduce the gap width of the second gap 21 when it is necessary to cut the film material 30.

[0040] In some embodiments, Figure 3-Figure 5 As shown, the first elastic member 223 abuts between the first diaphragm plate 23 and the first mounting member 221 , and the second elastic member 224 abuts between the first diaphragm plate 23 and the second mounting member 222 .

[0041] Since the clamping driving member 22 includes the first mounting member 221, the second mounting member 222, the first elastic member 223 and the second elastic member 224, and the first diaphragm plate 23 and the second diaphragm plate 24 are arranged opposite to each other, the first elastic member 223 abuts between the first diaphragm plate 23 and the first mounting member 221, and the second elastic member 224 abuts between the first diaphragm plate 23 and the first mounting member 221, it is convenient to realize that the gap width of the second gap 21 between the first diaphragm plate 23 and the second diaphragm plate 24 is variable.

[0042] When the film material 30 needs to be cut, the first elastic member 223 and the second elastic member 224 are in a compressed state, so elastic force can be provided to push the first film-smoothing plate 23 toward the second film-smoothing plate 24 to reduce the gap width of the second gap 21 .

[0043] In some embodiments, the first elastic member 223 and the second elastic member 224 may be springs. In other embodiments, the first elastic member 223 and the second elastic member 224 may also be other elastic objects.

[0044] In some embodiments, Figure 4 and Figure 5 As shown, the clamping drive member 22 further includes a third elastic member 225 and a fourth elastic member 226. The third elastic member 225 and the fourth elastic member 226 are used to provide elastic force to push the second film-smoothing plate 24 close to the first film-smoothing plate 23 to reduce the gap width of the second gap 21 when the film material 30 needs to be cut.

[0045] In some embodiments, the third elastic member 225 abuts between the second diaphragm plate 24 and the first mounting member 221 , and the fourth elastic member 226 abuts between the second diaphragm plate 24 and the second mounting member 222 .

[0046] The clamping driving member 22 includes a first mounting member 221, a second mounting member 222, a first elastic member 223, a second elastic member 224, a third elastic member 225 and a fourth elastic member 226, and the first diaphragm plate 23 and the second diaphragm plate 24 are arranged opposite to each other, the first elastic member 223 abuts between the first diaphragm plate 23 and the first mounting member 221, the second elastic member 224 abuts between the first diaphragm plate 23 and the first mounting member 221, and the third elastic member 225 abuts between the second diaphragm plate 24 and the first mounting member 221. The fourth elastic member 226 abuts between the second membrane plate 24 and the second mounting member 222, so that the first membrane plate 23 and the second membrane plate 24 can clamp and fix the guide assembly 10 to at least part of the membrane 30 from one side of the membrane cutting position A to the cutting position of the membrane 30, while the second gap 21 between the first membrane plate 23 and the second membrane plate 24 can be larger, so as to better ensure that the membrane 30 passes through the second gap 21 between the first membrane plate 23 and the second membrane plate 24 without friction.

[0047] In some embodiments, the third elastic member 225 and the fourth elastic member 226 may be springs. In other embodiments, the third elastic member 225 and the fourth elastic member 226 may also be other elastic objects.

[0048] In some embodiments, Figure 2 and Figure 3 As shown, the film stroking mechanism 20 further includes a supporting member 25 , and the supporting member 25 is used to increase the gap width of the second gap 21 .

[0049] In some embodiments, the support member 25 is located on the same side of the first membrane plate 23 and the second membrane plate 24. When the first membrane plate 23 and the second membrane plate 24 move toward the side close to the support member 25, the support member 25 is inserted between the first membrane plate 23 and the second membrane plate 24 to increase the gap width of the second gap 21.

[0050] Therefore, the film material 30 can pass through the second gap 21 between the first diaphragm plate 23 and the second diaphragm plate 24 without friction.

[0051] The size of the supporting member 25 can be set according to actual needs, so that the gap width of the second gap 21 is increased to a required size.

[0052] The shape of the supporting member 25 may be, but is not limited to, a block, a strip, a column, etc.

[0053] In some embodiments, Figure 4 and Figure 5 As shown, the clamping drive member 22 further includes a first guide member 227 and a second guide member 228. The first diaphragm plate 23 and the second diaphragm plate 24 are respectively provided with corresponding first through holes 231 and second through holes 241. The first guide member 227 is inserted into the first through holes 231 and the second through holes 241, and both ends are fixed to opposite sides of the first mounting member 221. The first diaphragm plate 23 and the second diaphragm plate 24 are also respectively provided with corresponding third through holes 232 and fourth through holes 242. The second guide member 228 is inserted into the third through holes 232 and the fourth through holes 242, and both ends are fixed to opposite sides of the second mounting member 222. The first diaphragm plate 23 and the second diaphragm plate 24 can both move relative to the first guide member 227 and the second guide member 228.

[0054] Since the supporting force of the first elastic member 223, the second elastic member 224, the third elastic member 225 and the fourth elastic member 226 on the first diaphragm plate 23 and the second diaphragm plate 24 is limited, the supporting force on the first diaphragm plate 23 and the second diaphragm plate 24 can be strengthened by providing the first guide member 227 and the second guide member 228. At the same time, when the size of the second gap 21 between the first diaphragm plate 23 and the second diaphragm plate 24 changes, the first diaphragm plate 23 and the second diaphragm plate 24 can be guided to avoid the position deviation of the first diaphragm plate 23 and the second diaphragm plate 24.

[0055] In some embodiments, Figure 2 and Figure 3 As shown, the film-stretching mechanism 20 also includes a frame 26, and the guide assembly 10 is installed on the frame 26. The film-stretching mechanism 20 also includes a displacement driving member 260, and the displacement driving member 260 is installed on the frame 26. The displacement driving member 260 is connected to the clamping driving member 22, and the displacement driving member 260 drives the clamping driving member 22 to drive the first film-stretching plate 23 and the second film-stretching plate 24 to move toward the film material cutting position A side or away from the film material cutting position A side.

[0056] Therefore, the first film-smoothing plate 23 and the second film-smoothing plate 24 can not only move toward or away from each other, but also move toward the film material cutting position A or away from the film material cutting position A.

[0057] In some embodiments, the frame 26 includes a first support member 261 and a second support member 262, the first support member 261 and the second support member 262 are arranged opposite to each other, and the guide assembly 10 is connected between the first support member 261 and the second support member 262. The displacement driving member 260 includes a first displacement driving member 2601 and a second displacement driving member 2602, the first displacement driving member 2601 is arranged on the first support member 261, and the second displacement driving member 2602 is arranged on the second support member 262, the first mounting member 221 is connected to the first displacement driving member 2601, and the second mounting member 222 is connected to the second displacement driving member 2602, and the first displacement driving member 2601 and the second displacement driving member 2602 drive the first mounting member 221 and the second mounting member 222 to drive the first film smoothing plate 23 and the second film smoothing plate 24 to move toward the film material cutting position A side or away from the film material cutting position A side.

[0058] Therefore, when the film material 30 needs to be cut, but the first film-smoothing plate 23 and the second film-smoothing plate 24 are not at the preset position, the first film-smoothing plate 23 and the second film-smoothing plate 24 can be moved to the preset position.

[0059] Among them, the first displacement driving member 2601 and the second displacement driving member 2602 are also used to drive the first mounting member 221 and the second mounting member 222 to drive the first film-straightening plate 23 and the second film-straightening plate 24 to move to a position where the supporting member 25 can be inserted between the first film-straightening plate 23 and the second film-straightening plate 24 when the film material 30 needs to be unrolled, thereby increasing the second gap 21 between the first film-straightening plate 23 and the second film-straightening plate 24.

[0060] Among them, the first displacement driving member 2601 and the second displacement driving member 2602 can be, but are not limited to, displacement driving members such as air cylinders and motors.

[0061] In some embodiments, as Figure 3 shown, a fifth through hole 2610 is provided on the first support member 261, a sixth through hole 2620 is provided on the second support member 262, and the fifth through hole 2610 and the sixth through hole 2620 are arranged opposite to each other. The first displacement driving member 2601 is disposed on a side of the first support member 261 away from the second support member 262, and the first mounting member 221 is inserted through the fifth through hole 2610 and can move in the fifth through hole 2610. The second displacement driving member 2602 is disposed on a side of the second support member 262 away from the first support member 261, and the second mounting member 222 is inserted through the sixth through hole 2620 and can move in the sixth through hole 2620.

[0062] Thus, the first displacement driving member 2601 is disposed on a side of the first support member 261 away from the second support member 262, and the second displacement driving member 2602 is disposed on a side of the second support member 262 away from the first support member 261, which can avoid occupying the space on the side of the first support member 261 close to the second support member 262 and the side of the second support member 262 close to the first support member 261. Thus, it is more convenient to arrange and set the unrolling mechanism 40 and the like between the first support member 261 and the second support member 262.

[0063] In some embodiments, as Figure 3 shown in Figure 4 and Figure 3 shown in Figure 5 and

[0064] shown, the first mounting member 221 is provided with a first opening 2211, and the second mounting member 222 is provided with a second opening 2221. The first opening 2211 and the second opening 2221 are arranged opposite to each other. One end of the first film-straightening plate 23 and the second film-straightening plate 24 is located in the first opening 2211, and the other end of the first film-straightening plate 23 and the second film-straightening plate 24 is located in the second opening 2221.

[0065] In some embodiments, Figure 3 and Figure 4 As shown, the first mounting member 221 further includes a first connecting portion 2212, which is disposed in the fifth through hole 2610, one end of the first connecting portion 2212 is connected to the first displacement driving member 2601, and the other end of the first connecting portion 2212 is connected to the first opening 2211. Figure 3 and Figure 5 As shown, the second mounting member 222 further includes a second connecting portion 2222 , which passes through the sixth through hole 2620 , one end of the second connecting portion 2222 is connected to the second displacement driving member 2602 , and the other end of the second connecting portion 2222 is connected to the second opening portion 2221 .

[0066] In some embodiments, Figure 2 and Figure 3 As shown, the film-smoothing mechanism 20 further includes a third mounting member 27, the two ends of which are respectively connected to the first support member 261 and the second support member 262, and the supporting member 25 is disposed on one side of the third mounting member 27 facing the first film-smoothing plate 23 and the second film-smoothing plate 24. The guiding assembly 10 is closer to the film material cutting position A than the third mounting member 27.

[0067] Thus, when it is necessary to cut the film material 30, under the drive of the first displacement driving member 2601 and the second displacement driving member 2602, the first film smoothing plate 23 and the second film smoothing plate 24 connected by the supporting member 25 move toward the film material cutting position A. At least under the action of the first elastic member 223 and the second elastic member 224, the second gap 21 between the first film smoothing plate 23 and the second film smoothing plate 24 gradually decreases, and then the film material 30 can be smoothed in the process of moving toward the film material cutting position A.

[0068] In some embodiments, the sum of the thicknesses of the first membrane plate 23 and the second membrane plate 24 is smaller than the gap width of the first gap 11 of the guide assembly 10. When the first displacement drive member 2601 and the second displacement drive member 2602 drive the first mounting member 221 and the second mounting member 222 to move the first membrane plate 23 and the second membrane plate 24 toward the film material cutting position A, at least part of the structure of the first membrane plate 23 and the second membrane plate 24 is closer to the film material cutting position A than the side of the guide assembly close to the cutting position of the film material 30.

[0069] Therefore, the first film-smoothing plate 23 and the second film-smoothing plate 24 can pass through the first gap 11 of the guide assembly 10, making it easier for the first film-smoothing plate 23 and the second film-smoothing plate 24 to fix at least part of the film 30 on the side of the guide assembly 10 close to the film cutting position A to the film cutting position A.

[0070] In some embodiments, the first displacement driving member 2601 and the second displacement driving member 2602 drive the first mounting member 221 and the second mounting member 222 to drive the first membrane plate 23 and the second membrane plate 24 to a preset position, where the side of the first membrane plate 23 and the second membrane plate 24 close to the film material cutting position A is 2 to 20 mm away from the side of the guide assembly 10 close to the cutting position of the film material 30.

[0071] When the side of the first film-smoothing plate 23 and the second film-smoothing plate 24 close to the film cutting position A is 10 to 20 mm away from the side of the guide assembly 10 close to the cutting position of the film 30 , the free end 31 of the cut film can be better prevented from winding around the guide assembly 10 .

[0072] In some embodiments, the film material cutting position A is 15 mm away from the first film smoothing plate 23 and the second film smoothing plate 24 near the film material cutting position A. Thus, the film material pulling mechanism 50 can pull the film material 30 conveniently during the next lamination.

[0073] In other embodiments, the distance between the film material cutting position A and the first film-smoothing plate 23 and the second film-smoothing plate 24 close to the film material cutting position A may also be other values.

[0074] The above is an implementation method of the embodiment of the present application. It should be pointed out that for ordinary technicians in this technical field, several improvements and modifications can be made without departing from the principles of the embodiment of the present application. These improvements and modifications are also considered to be within the scope of protection of the present application.
