Description

Technical Field

[0001] The utility model relates to the technical field of battery manufacturing equipment, in particular to a roll changing device and a winding device. Background Art

[0002] In the actual production process of batteries, the positive electrode tape, the separator tape and the negative electrode tape are first wound into a battery cell by winding, and then the battery cell is transported to the assembly line for assembly. Generally, the electrode is provided by unwinding the material roll, so when a electrode roll is about to run out, it needs to be replaced with a new electrode roll. During the replacement process, it is necessary to splice the tape, that is, use tape to bond the unwound electrode tape (i.e., the working electrode) with the new electrode tape (i.e., the spare tape) unwound from the newly replaced electrode roll (i.e., the spare tape).

[0003] In the case of a narrow pole piece tape, such as the pole piece tape of a button-type battery cell, in order to ensure the firmness of the tape connection, tape needs to be pasted on both sides of the working tape and the spare tape. However, when the tape is connected by pasting tape on both sides, the pole piece tape and the tape are prone to position deviation, and the tapes pasted on both sides are not completely aligned with each other, resulting in the adhesive surface of the tape being exposed. During the tape feeding process, the exposed adhesive surface is prone to adhesion to components such as the roller, which has an adverse effect on the performance of the pole piece tape. Utility Model Content

[0044] See also Figures 1 to 4 An embodiment of the utility model provides a roll changing device, including a first unwinding assembly 10a, a second unwinding assembly 10b, a glue applying assembly (not shown) and a glue rolling assembly 30.

[0045] The first unwinding assembly 10a is loaded with a material roll and can drive the material roll to unwind and output a material tape. The second unwinding assembly 10b is also loaded with a material roll and can drive the material roll to unwind and output a material tape. When the first unwinding assembly 10a is used for unwinding, the material roll on the first unwinding assembly 10a is the working material roll A, and the material tape that the first unwinding assembly 10a drives the working material roll A on it to unwind and output is the working material tape a1. At this time, the material roll on the second unwinding assembly 10b is the spare material roll B, and the material tape on the spare material roll B is the spare material tape a2. When the working material roll A on the first unwinding assembly 10a is about to be unwound, it is necessary to switch the state of unwinding by the first unwinding assembly 10a to the state of unwinding by the second unwinding assembly 10b (i.e., changing the roll). After the roll change is completed, the material roll on the second unwinding assembly 10b is the working material roll A, and the material roll replaced on the first unwinding assembly 10a is the spare material roll B.

[0046] When the second unwinding assembly 10b is used for unwinding, the material roll on the second unwinding assembly 10b is the working material roll A, and the material strip unwound by the second unwinding assembly 10b driving the working material roll A thereon is the working material strip a1. At this time, the material roll on the first unwinding assembly 10a is the spare material roll B, and the material strip on the spare material roll B is the spare material strip a2. When the working material roll A on the second unwinding assembly 10b is about to be unwound, it is necessary to switch the state of unwinding by the second unwinding assembly 10b to the state of unwinding by the first unwinding assembly 10a (i.e., changing the roll). After the roll change is completed, the material roll on the first unwinding assembly 10a is the working material roll A, and the material roll replaced on the second unwinding assembly 10b is the spare material roll B.

[0047] The glue sticking component is arranged downstream of the first unwinding component 10a and the second unwinding component 10b, and has a glue absorbing surface a4 for absorbing the adhesive tape a3. It can be understood that one side of the adhesive tape a3 is a glue-attached surface, and the other side is a non-glue-attached surface. When the adhesive tape a3 is adsorbed on the glue absorbing surface a4, the non-glue-attached surface of the adhesive tape a3 fits with the glue absorbing surface a4. The glue sticking component is used to clamp and cut the passing working tape a1 and spare tape a2, and to stick the downstream cut end a11 of the working tape a1 and the upstream cut end a21 of the spare tape a2 to the adhesive tape a3 on the glue absorbing surface a4. The adhesive absorbing surface a4 is provided with a blowing hole a41 (see Figure 5 The glue rolling assembly 30 has a roller 31, and the glue rolling assembly 30 can controllably drive the roller 31 to abut against the glue absorbing surface a4 and roll along the glue absorbing surface a4, so as to roll the edge of the blown adhesive tape a3 to the side of the working material tape a1 and the spare material tape a2 away from the glue absorbing surface a4, so that the adhesive tape a3 is wrapped around the downstream cut end a11 of the working material tape a1 and the upstream cut end a21 of the spare material tape a2, so that the working material tape a1 and the spare material tape a2 are connected through the adhesive tape a3.

[0048] It should be noted that the upstream and downstream in this article are relative to the conveying direction of the working material tape a1 and the spare material tape a2, that is, the position that the working material tape a1 and the spare material tape a2 reach first during the conveying process is the upstream, and the position that they reach later is the downstream. After the working material tape a1 is cut by the adhesive component, the cut working material tape a1 forms two cut ends, of which the cut end located downstream of the cutting position is the downstream cut end a11 of the working material tape a1, and the cut end located upstream of the cutting position is the upstream cut end of the working material tape a1. Similarly, after the spare material tape a2 is cut by the adhesive component, the cut spare material tape a2 forms two cut ends, of which the cut end located downstream of the cutting position is the downstream cut end of the spare material tape a2, and the cut end located upstream of the cutting position is the upstream cut end a21 of the spare material tape a2.

[0049] The above-mentioned roll changing device is explained by taking the first unwinding component 10a unwinding and outputting the working material tape a1 and the second unwinding component 10b unwinding and outputting the spare material tape a2 as an example. When the working material roll A on the first unwinding component 10a is about to be unwound and needs to be changed, first, the glue sticking component clamps the passing working material tape a1 and the spare material tape a2, and cuts the working material tape a1 and the spare material tape a2; then, the downstream cut end a11 of the working material tape a1 and the upstream cut end a21 of the spare material tape a2 are pasted to the tape a3 on the glue suction surface a4; at this time, at least one side edge of the tape a3 is not covered by the working material tape a1 and the spare material tape a2; then, the air blowing hole a41 on the glue suction surface a4 is used to blow the uncovered edge of the tape a3 away from the glue suction surface a4. At the same time, the glue rolling assembly 30 drives the roller 31 to roll along the glue absorbing surface a4 until the edge of the blown tape a3 is rolled to the side of the downstream cut end a11 of the working tape a1 and the upstream cut end a21 of the spare tape a2 away from the glue absorbing surface a4; at this time, the tape a3 wraps the downstream cut end a11 of the working tape a1 and the upstream cut end a21 of the spare tape a2, so that the downstream cut end a11 of the working tape a1 and the upstream cut end a21 of the spare tape a2 are connected by the tape a3; finally, the glue absorbing surface a4 stops adsorbing the tape a3, and the second unwinding assembly 10b replaces the first unwinding assembly 10a to unwind and output the tape downstream, that is, the material roll on the second unwinding assembly 10b serves as the working material roll A, and the second unwinding assembly 10b drives the material roll thereon to unwind and output the tape as the working material tape a1. At this time, the new material roll can be replaced on the first unwinding component 10a, and the new material roll on the first unwinding component 10a is used as the spare material roll B. The spare material tape a2 on the spare material roll B is pulled to the downstream of the glue application component to prepare for the next roll change.

[0050] In this way, the roll-changing device in the present application uses the blowing holes a41 on the glue suction surface a4 to blow up the edge of the tape a3, and then uses the roller 31 of the glue rolling assembly 30 to roll the blown edge of the tape a3 to the downstream cut end a11 of the working material tape a1 and the upstream cut end a21 of the spare material tape a2 away from the glue suction surface a4, thereby using the tape a3 to wrap the downstream cut end a11 of the working material tape a1 and the upstream cut end a21 of the spare material tape a2, so that the adhesive surface of the tape a3 is adhered to the downstream cut end a11 of the working material tape a1 and the upstream cut end a21 of the spare material tape a2, avoiding the adhesive surface of the tape a3 from being exposed and sticking to components such as rollers during the subsequent tape feeding process, thereby avoiding adverse effects on the performance of the tape.

[0051] See also Figure 5Specifically in the embodiment, the adhesive absorption surface a4 has an adsorption area and a blowing area. The blowing area is located on opposite sides of the adsorption area. The adsorption area is provided with a plurality of adsorption holes a42 for adsorbing the adhesive tape a3. The blowing area is provided with a plurality of blowing holes a41, so that the edges of the adhesive tape a3 covering the blowing area are blown up by each of the blowing holes a41. In this way, in actual use, the negative pressure generated by each of the adsorption holes a42 is used to adsorb and fix the adhesive tape a3 on the adhesive absorption surface a4, and at this time, the edges of the adhesive tape a3 on opposite sides respectively cover the blowing areas on opposite sides of the adsorption area. When the downstream cut end a11 of the working tape a1 and the upstream cut end a21 of the spare tape a2 are pasted to the tape a3 on the adhesive absorption surface a4, the downstream cut end a11 of the working tape a1 and the upstream cut end a21 of the spare tape a2 cover the area of ​​the tape a3 corresponding to the adsorption area, and the edges of the tape a3 corresponding to the blowing area are not covered by the downstream cut end a11 of the working tape a1 and the upstream cut end a21 of the spare tape a2, so that the blowing area is not covered by the downstream cut end a11 of the working tape a1 and the upstream cut end a21 of the spare tape a2. When blowing air, the blowing holes a41 in the area can blow the opposite side edges of the adhesive tape a3 away from the adhesive absorption surface a4, so that when the roller 31 of the adhesive rolling assembly 30 rolls along the adhesive absorption surface a4, the opposite side edges of the adhesive tape a3 can be rolled to the side of the downstream cut end a11 of the working material tape a1 and the upstream cut end a21 of the spare material tape a2 away from the adhesive absorption surface a4, that is, the adhesive tape a3 wraps the downstream cut end a11 of the working material tape a1 and the upstream cut end a21 of the spare material tape a2.

[0052] It should be noted that it is not limited to rolling the opposite side edges of the tape a3 to the side of the downstream cut end a11 of the working tape a1 and the upstream cut end a21 of the spare tape a2 away from the glue absorption surface a4, but only one side edge of the tape a3 can be rolled to the side of the downstream cut end a11 of the working tape a1 and the upstream cut end a21 of the spare tape a2 away from the glue absorption surface a4. For example, when the downstream cut end a11 of the working material tape a1 and the upstream cut end a21 of the spare material tape a2 are pasted to the tape a3 on the glue absorption surface a4, only one side edge of the tape a3 is not covered by the downstream cut end a11 of the working material tape a1 and the upstream cut end a21 of the spare material tape a2. Therefore, only the blowing hole a41 corresponding to the uncovered side edge of the tape a3 needs to be blown to blow up the uncovered side edge of the tape a3, so that the roller 31 of the glue rolling assembly 30 can roll the blown side edge of the tape a3 to the side of the downstream cut end a11 of the working material tape a1 and the upstream cut end a21 of the spare material tape a2 away from the glue absorption surface a4.

[0053] It should also be noted that in the embodiment where only one side edge of the adhesive tape a3 needs to be rolled, a blowing area may be provided only on one side of the adsorption area, so as to use the blowing area to blow up one side edge of the adhesive tape.

[0054] See also Figure 4 and Figure 7 Specifically, in the embodiment, the rubber rolling assembly 30 includes a rubber rolling driving member 32, a moving seat 33, a floating seat 34 and a buffer member 36. The moving seat 33 is installed at the driving end of the rubber rolling driving member 32, so that the rubber rolling driving member 32 can drive the moving seat 33 to move. The floating seat 34 is movably connected to the moving seat 33. The roller 31 is rotatably connected to the floating seat 34, so that the roller 31 can float relative to the moving seat 33 along with the floating seat 34. The moving seat 33 can controllably drive the roller 31 to press against the rubber suction surface a4, and roll along the rubber suction surface a4 until the blown edge of the adhesive tape a3 is rolled to the side of the downstream cut end a11 of the working material tape a1 and the upstream cut end a21 of the spare material tape a2 away from the rubber suction surface a4. The buffer member 36 is abutted between the moving seat 33 and the floating seat 34, so that the floating seat 34 can overcome the elastic force of the buffer member 36 and float relative to the moving seat 33. Thus, when rolling is required, first, the moving seat 33 is controlled to move toward the adhesive absorbing surface a4, so that the roller 31 is pressed against the adhesive absorbing surface a4. At this time, under the action of the pressing force applied by the adhesive absorbing surface a4 to the roller 31, the floating seat 34 floats toward the moving seat 33 to a certain extent, so that the buffer 36 is further compressed, and the buffer 36 plays a buffering role to prevent the roller 31 from having a hard impact with the adhesive absorbing surface a4.

[0055] Specifically in the embodiment, one end of the floating seat 34 is rotatably connected to the moving seat 33, and the roller 31 is rotatably connected to the other end of the floating seat 34, so that under the action of the pressure applied by the adhesive suction surface a4 to the roller 31, the floating seat 34 rotates a certain angle toward the moving seat 33 to further compress the buffer 36, so that the buffer 36 plays a buffering role to prevent the roller 31 from having a hard impact with the adhesive suction surface a4. Optionally, the buffer 36 can be a spring or a cylinder.

[0056] It should be noted that the elastic floating of the floating seat 34 is not limited to the method of rotating the floating seat 34 relative to the moving seat 33. In other embodiments, the floating seat 34 can also be arranged to be movable relative to the moving seat 33 to achieve the elastic floating of the floating seat 34, which is not limited here.

[0057] See also Figures 4 to 6In the embodiment of the present application, the glue sticking assembly includes an adsorption mechanism 21 and a glue sticking mechanism 22. The adsorption mechanism 21 and the glue sticking mechanism 22 are arranged at intervals along the first direction X1, and a tape splicing channel (not marked in the figure) is formed between the two for the working material tape a1 and the spare material tape a2 to pass through. The working material tape a1 and the spare material tape a2 pass through the tape splicing channel approximately along the third direction X3, and the third direction X3 is perpendicular to the first direction X1. In other words, the working material tape a1 unwound and output by one of the first unwinding assembly 10a and the second unwinding assembly 10b passes through the tape splicing channel approximately along the third direction X3, and is further transported downstream. The material roll on the other of the first unwinding assembly 10a and the second unwinding assembly 10b is a spare material roll B, and the spare material tape a2 on the spare material roll B is pulled through the tape splicing channel approximately along the third direction X3 to prepare for subsequent roll replacement. The suction mechanism 21 and the glue sticking mechanism 22 can be controlled to move closer to or farther from each other along the first direction X1 to clamp or release the working material tape a1 and the spare material tape a2 passing through the tape connection channel. The above-mentioned glue suction surface a4 is located on the glue sticking mechanism 22, and the glue sticking mechanism 22 is used to cut the clamped working material tape a1 and the spare material tape a2. The suction mechanism 21 is used to suction the downstream cut end a11 of the working material tape a1 and the upstream cut end a21 of the spare material tape a2, and stick the suctioned downstream cut end a11 of the working material tape a1 and the upstream cut end a21 of the spare material tape a2 to the adhesive tape a3 on the suction surface a4.

[0058] See also Figure 4 and Figure 7 Optionally, the glue rolling driving member 32 can drive the moving seat 33 to move along the second direction X2, so as to drive the roller 31 to enter or exit between the adsorption mechanism 21 and the glue sticking mechanism 22 along the second direction X2. The second direction X2 is perpendicular to the first direction X1 and the third direction X3. In this way, when glue rolling is required, the glue rolling driving member 32 drives the moving seat 33 to move along the second direction X2 until the roller 31 is located between the adsorption mechanism 21 and the glue sticking mechanism 22, and at this time, the roller 31 abuts against the glue suction surface a4 of the glue sticking mechanism 22. When the roller 31 contacts the adhesive suction surface a4, the edge of the adhesive tape a3 on the adhesive suction surface a4 is blown by the blowing hole a41, and the adhesive rolling driving member 32 drives the roller 31 to move along the second direction X2, so that the roller 31 rolls along the adhesive suction surface a4 until the edge of the adhesive tape a3 that is blown up is rolled to the side of the downstream cut end a11 of the working material tape a1 and the upstream cut end a21 of the spare material tape a2 away from the adhesive suction surface a4. It should be noted that in other embodiments, when the roller 31 enters between the adsorption mechanism 21 and the adhesive pasting mechanism 22 along the second direction X2, there is still a certain distance between the roller 31 and the adhesive suction surface a4 on the adhesive pasting mechanism 22 in the first direction X, and the adhesive pasting mechanism 22 needs to be controlled to move close to the adsorption mechanism 21 along the first direction X1 so that the roller 31 can be pressed against the adhesive suction surface a4.

[0059] Optionally, the rubber rolling drive member 32 includes a first rubber rolling cylinder 321 and a second rubber rolling cylinder 322 installed at the driving end of the first rubber rolling cylinder 321. The above-mentioned moving seat 33 is installed at the driving end of the second rubber rolling cylinder 322, and the first rubber rolling cylinder 321 and the second rubber rolling cylinder 322 are both used to drive the moving seat 33 to move along the second direction X2, thereby driving the roller 31 to move along the second direction X2. In this way, when the driving end of the first rubber rolling cylinder 321 is extended, the moving seat 33 drives the roller 31 to enter the position between the adsorption mechanism 21 and the glue sticking mechanism 22. When the driving end of the second rubber rolling cylinder 322 is extended, the moving seat 33 drives the roller 31 to roll along the glue suction surface a4 to complete the rubber rolling. When the driving ends of the first rubber rolling cylinder 321 and the second rubber rolling cylinder 322 are retracted, the roller 31 withdraws from the position between the adsorption mechanism 21 and the glue sticking mechanism 22. Of course, the glue rolling driving member 32 may also adopt other linear driving modules, as long as it can drive the roller 31 to complete glue rolling, and no limitation is made here.

[0060] Please continue to see Figure 4 As shown, the roll changing device further includes a first winding member 60a and a second winding member 60b. The first winding member 60a and the second winding member 60b are both arranged downstream of the tape splicing passage and are respectively located on opposite sides of the working tape a1 passing through the tape splicing passage. The first winding member 60a and the second winding member 60b can be selectively connected to the spare tape a2 passing through the tape splicing passage so as to be able to wind up the downstream cut end of the spare tape a2 after the spare tape a2 is cut.

[0061] When the material roll on the first unwinding assembly 10a is the working material roll A, and the material roll on the second unwinding assembly 10b is the standby material roll B, the first unwinding assembly 10a drives the working material roll A thereon to unwind and output the working material tape a1 downstream, and the working material tape a1 passes through the tape splicing channel roughly along the third direction X3 and then continues to be transported downstream. At this time, the standby material tape a2 on the standby material roll B is pulled through the tape splicing channel and then fixed on the second winding member 60b, in preparation for the subsequent roll change.

[0062] When the material roll on the second unwinding assembly 10b is the working material roll A, and the material roll on the first unwinding assembly 10a is the standby material roll B, the second unwinding assembly 10b drives the working material roll A thereon to unwind and output the working material tape a1 downstream, and the working material tape a1 passes through the tape splicing channel roughly along the third direction X3 and then continues to be transported downstream. At this time, the standby material tape a2 on the standby material roll B is pulled through the tape splicing channel and then fixed on the first winding member 60a, in preparation for the subsequent roll change.

[0063] See also Figures 4 to 6Specifically, in the embodiment, the glue sticking mechanism 22 includes a rotating seat 225, a first adsorption seat 221, a second adsorption seat 222, a cutter 223 and a glue sticking seat 224. The first adsorption seat 221 and the second adsorption seat 222 are arranged on the same side of the rotating seat 225, and the cutter 223 is arranged on the rotating seat 225 and is located between the first adsorption seat 221 and the second adsorption seat 222. The glue sticking seat 224 is arranged on the other side of the rotating seat 225, and the above-mentioned glue suction surface a4 is located on the glue sticking seat 224. The rotating seat 225 can be controlled to rotate to the first state or the second state, and the rotating seat 225 and the adsorption mechanism 21 can be controlled to approach or move away from each other along the first direction X1.

[0064] When the rotating seat 225 rotates to the first state, the first adsorption seat 221 and the second adsorption seat 222 face the adsorption mechanism 21. At this time, if the rotating seat 225 and the adsorption mechanism 21 approach each other along the first direction X1, the first adsorption seat 221 and the second adsorption seat 222 can clamp the working material belt a1 and the spare material belt a2 passing through the belt connecting channel together with the adsorption mechanism 21, so that the cutter 223 can cut off the clamped working material belt a1 and the spare material belt a2.

[0065] When the rotating seat 225 rotates to the second state, the glue absorbing surface a4 of the glue sticking seat 224 faces the adsorption mechanism 21. At this time, if the rotating seat 225 and the adsorption mechanism 21 approach each other along the first direction X1, the adsorption mechanism 21 can abut against the glue absorbing surface a4 of the glue sticking seat 224, so that the downstream cut end a11 of the working material tape a1 and the upstream cut end a21 of the spare material tape a2 adsorbed by the adsorption mechanism 21 are adhered to the tape a3 on the glue absorbing surface a4 of the glue sticking seat 224.

[0066] Furthermore, the glue sticking mechanism 22 further includes a first elastic member C1 (see Figure 6 ) and the second elastic member C2 (see Figure 6). Both the first adsorption seat 221 and the second adsorption seat 222 are movably connected to the rotating seat 225. The first elastic member C1 abuts between the first adsorption seat 221 and the rotating seat 225, and is used to provide a pre-tightening force that makes the first adsorption seat 221 have a tendency to move away from the rotating seat 225. The second elastic member C2 abuts between the second adsorption seat 222 and the rotating seat 225, and is used to provide a pre-tightening force that makes the second adsorption seat 222 have a tendency to move away from the rotating seat 225. In this way, when the rotating seat 225 rotates to the first state, the rotating seat 225 and the adsorption mechanism 21 are controlled to approach each other along the first direction X1, so that the first adsorption seat 221 and the second adsorption seat 222 press the passing working material belt a1 and the spare material belt a2 onto the adsorption mechanism 21. As the rotating seat 225 and the adsorption mechanism 21 continue to approach each other along the first direction X1, the first elastic member C1 and the second elastic member C2 are further compressed, so that the cutter 223 extends from between the first adsorption seat 221 and the second adsorption seat 222 to cut off the clamped working tape a1 and spare tape a2. Optionally, the first elastic member C1 and the second elastic member C2 can be springs.

[0067] Furthermore, the adhesive laminating mechanism 22 further includes a movable seat 229, a rotating shaft 226, a telescopic member 228 and an adapter block 227. The movable seat 229 can be controlled to approach or move away from the adsorption mechanism 21 along the first direction X1. The rotating shaft 226 is rotatably connected to the movable seat 229, and the rotating seat 225 and the adapter block 227 are both mounted on the rotating shaft 226. One end of the telescopic member 228 is hinged to the adapter block 227, and the other end of the telescopic member 228 is hinged to the movable seat 229. The telescopic member 228 can be controlled to drive the rotating shaft 226 to rotate through the adapter block 227 in a self-expanding manner, so that the rotating shaft 226 drives the rotating seat 225 to rotate to the above-mentioned first state or second state. In this way, in actual use, when the telescopic member 228 is extended, the shaft 226 is driven to rotate through the adapter block 227 until the shaft 226 drives the rotating seat 225 to rotate to the first state, at which time the first adsorption seat 221 and the second adsorption seat 222 on the rotating seat 225 face the adsorption mechanism 21; when the telescopic member 228 is contracted, the shaft 226 is driven to rotate in the opposite direction through the adapter block 227 until the shaft 226 drives the rotating seat 225 to rotate to the second state, at which time the adhesive surface a4 of the adhesive seat 224 on the rotating seat 225 faces the adsorption mechanism 21.

[0068] Furthermore, the glue sticking mechanism 22 further includes a first driving member 220, and the above-mentioned moving seat 229 is installed at the driving end of the first driving member 220, so that the first driving member 220 can drive the moving seat 229 to approach or move away from the adsorption mechanism 21 along the first direction X1. In this way, the first driving member 220 drives the moving seat 229 to approach or move away from the adsorption mechanism 21 along the first direction X1, thereby driving the first adsorption seat 221 and the second adsorption seat 222 to approach or move away from the adsorption mechanism 21, or driving the glue sticking seat 224 to approach or move away from the adsorption mechanism 21. Optionally, the first driving member 220 can be a cylinder.

[0069] See also Figure 4 and Figure 8 In the embodiment of the present application, the adsorption mechanism 21 includes a second driving member 214, a mounting seat 213, a third adsorption seat 211 and a fourth adsorption seat 212. The mounting seat 213 is installed at the driving end of the second driving member 214, so that the second driving member 214 can drive the mounting seat 213 to approach or move away from the gluing mechanism 22 along the first direction X1. The third adsorption seat 211 and the fourth adsorption seat 212 are both installed on the side of the mounting seat 213 facing the gluing mechanism 22, so that when the second driving member 214 drives the mounting seat 213 to move along the first direction X1, it can drive the third adsorption seat 211 and the fourth adsorption seat 212 to approach or move away from the gluing mechanism 22. The third adsorption seat 211 is located on the downstream side of the fourth adsorption seat 212, that is, the working material belt a1 passes through the fourth adsorption seat 212 and then passes through the third adsorption seat 211. When the rotating seat 225 rotates to the first state, the first adsorption seat 221 and the third adsorption seat 211 are opposite to each other along the first direction X1, and the second adsorption seat 222 and the fourth adsorption seat 212 are opposite to each other along the first direction X1, so that the first adsorption seat 221 and the third adsorption seat 211 can clamp the downstream cut end a11 of the working material tape a1 and the downstream cut end of the spare material tape a2, and the second adsorption seat 222 and the fourth adsorption seat 212 can clamp the upstream cut end of the working material tape a1 and the upstream cut end a21 of the spare material tape a2. When the rotating seat 225 rotates to the second state, the adhesive suction surface a4 of the adhesive sticking seat 224 and the third adsorption seat 211 and the fourth adsorption seat 212 are opposite to each other along the first direction X1, so that the third adsorption seat 211 and the fourth adsorption seat 212 can stick the downstream cut end a11 of the working material tape a1 and the upstream cut end a21 of the spare material tape a2, which are respectively adsorbed, to the adhesive tape a3 on the adhesive suction surface a4 of the adhesive sticking seat 224.

[0070] In this way, when the first unwinding assembly 10a unwinds and outputs the working tape a1 (i.e., the working tape a1 is located on the side of the spare tape a2 close to the adsorption mechanism 21 in the tape connection channel, and the spare tape a2 is located on the side of the working tape a1 close to the gluing mechanism 22), when the tape needs to be changed:

[0071] First, the mounting seat 213 and the moving seat 229 are controlled to approach each other along the first direction X1, so that the first adsorption seat 221 and the third adsorption seat 211 clamp the passing working material belt a1 and the spare material belt a2, and the second adsorption seat 222 and the fourth adsorption seat 212 also clamp the passing working material belt a1 and the spare material belt a2. As the mounting seat 213 and the moving seat 229 continue to approach along the first direction X1, the first adsorption seat 221 and the second adsorption seat 222 further compress the first elastic member C1 and the second elastic member C2 respectively, so that the cutter 223 protrudes from between the first adsorption seat 221 and the second adsorption seat 222 and cuts off the passing working material belt a1 and the spare material belt a2. At this time, the first adsorption seat 221 adsorbs the downstream cut end of the spare material belt a2, the second adsorption seat 222 adsorbs the upstream cut end a21 of the spare material belt a2, the third adsorption seat 211 adsorbs the downstream cut end a11 of the working material belt a1, and the fourth adsorption seat 212 adsorbs the upstream cut end of the working material belt a1.

[0072] Then, the mounting seat 213 and the movable seat 229 are controlled to move away from each other along the first direction X1, so that the first adsorption seat 221 and the third adsorption seat 211 respectively drive the downstream cut end of the spare material belt a2 to separate from the downstream cut end a11 of the working material belt a1, and at the same time, the second adsorption seat 222 and the fourth adsorption seat 212 respectively drive the upstream cut end a21 of the spare material belt a2 to separate from the upstream cut end of the working material belt a1.

[0073] Then, the second winding member 60b winds up the downstream cut end of the spare material tape a2 (at this time, the first adsorption seat 221 stops adsorbing the downstream cut end of the spare material tape a2), and the first unwinding component 10a winds up the upstream cut end of the working material tape a1 (at this time, the fourth adsorption seat 212 stops adsorbing the upstream cut end of the working material tape a1).

[0074] Then, the mounting seat 213 and the movable seat 229 are controlled to approach each other along the first direction X1 until the first adsorption seat 221 and the third adsorption seat 211 jointly clamp the downstream cut end a11 of the working material strip a1, and the second adsorption seat 222 and the fourth adsorption seat 212 jointly clamp the upstream cut end a21 of the spare material strip a2.

[0075] Then, the fourth adsorption seat 212 adsorbs the upstream cut end a21 of the spare material tape a2, the second adsorption seat 222 stops adsorbing the upstream cut end a21 of the spare material tape a2, and controls the mounting seat 213 and the movable seat 229 to move away from each other along the first direction X1, so that the third adsorption seat 211 adsorbs the downstream cut end a11 of the working material tape a1, and the fourth adsorption seat 212 adsorbs the upstream cut end a21 of the spare material tape a2.

[0076] Then, the telescopic member 228 drives the rotating shaft 226 to rotate through the adapter block 227 until the rotating shaft 226 drives the rotating seat 225 to rotate from the first state to the second state. At this time, the adhesive absorption surface a4 of the adhesive sticking seat 224 faces the third adsorption seat 211 and the fourth adsorption seat 212.

[0077] Then, the mounting seat 213 and the movable seat 229 are controlled to approach each other along the first direction X1 until the third adsorption seat 211 sticks the downstream cut end a11 of the working material tape a1 to the tape a3 on the adhesive absorption surface a4, and at the same time, the fourth adsorption seat 212 sticks the upstream cut end a21 of the spare material tape a2 to the tape a3 on the adhesive absorption surface a4.

[0078] Then, the third adsorption seat 211 stops adsorbing the downstream cut end a11 of the working material tape a1, and the fourth adsorption seat 212 stops adsorbing the upstream cut end a21 of the spare material tape a2, and controls the mounting seat 213 and the movable seat 229 to move away from each other along the first direction X1, so that the downstream cut end a11 of the working material tape a1, the upstream cut end a21 of the spare material tape a2 and the tape a3 follow the glue sticking seat 224 along the first direction X1 away from the adsorption mechanism 21.

[0079] Then, the blowing holes a41 on the adhesive absorption surface a4 blow air to blow the uncovered edge of the adhesive tape a3 away from the adhesive absorption surface a4. The control motion seat 33 drives the roller 31 to move along the second direction X2 to between the adsorption mechanism 21 and the adhesive application mechanism 22, so that the roller 31 is pressed against the adhesive absorption surface a4. The control motion seat 33 rolls along the adhesive absorption surface a4 until the edge of the adhesive tape a3 blown up by the blowing holes a41 is rolled to the side of the downstream cut end a11 of the working material tape a1 and the upstream cut end a21 of the spare material tape a2 away from the adhesive absorption surface a4.

[0080] Finally, the control moving seat 33 drives the roller 31 to withdraw from the position between the adsorption mechanism 21 and the glue sticking mechanism 22 along the second direction X2, and each adsorption hole a42 on the glue absorption surface a4 stops adsorbing the tape a3. At this time, the spare material roll B on the second unwinding component 10b serves as the working material roll A, and the second unwinding component 10b drives the material roll on it to unwind the output tape downstream as the working material tape a1. The newly replaced material roll on the first unwinding component 10a serves as the spare material roll B, and the spare material tape a2 on the spare material roll B is pulled through the tape connection channel and then fixed on the first winding member 60a to prepare for the next roll change. It should be noted that the roll changing step of the roll changing device of the present application is not limited to this. The above description is only used as an implementation method. As long as the switching between the working material tape and the spare material tape can be achieved, it is not limited here.

[0081] See also Figure 4As shown, in the embodiment of the present application, the roll changing device further includes a first roller 70a, a second roller 70b, a first movable plate 50a and a second movable plate 50b. The first roller 70a and the second roller 70b are arranged upstream and downstream of the above-mentioned belt splicing channel. Each first roller 70a is installed on the first movable plate 50a, and each second roller 70b is installed on the second movable plate 50b. The first movable plate 50a and the second movable plate 50b can be controlled to approach or move away from each other along the first direction X1, so as to drive the working material belt a1 and the spare material belt a2 passing through the belt splicing channel to approach or move away from each other through each first roller 70a and each second roller 70b. In this way, when it is necessary to change the roll, first control the first movable seat 229 and the second movable seat 229 to approach each other along the first direction X1, so that each first roller 70a and each second roller 70b drive the working material belt a1 and the spare material belt a2 passing through the belt connecting channel to approach each other, so that the working material belt a1 and the spare material belt a2 passing through the belt connecting channel are close enough to each other, so as to facilitate the subsequent clamping, cutting, gluing and rolling of the working material belt a1 and the spare material belt a2 by the adsorption mechanism 21, the gluing mechanism 22 and the glue rolling assembly 30.

[0082] Furthermore, the adsorption mechanism 21 is arranged on the first movable plate 50a, and the gluing mechanism 22 is arranged on the second movable plate 50b, so that when the first movable plate 50a and the second movable plate 50b approach each other along the first direction X1, the adsorption mechanism 21 and the gluing mechanism 22 can be driven to approach each other by a certain distance, which is beneficial to reducing the movement stroke when the adsorption mechanism 21 and the gluing mechanism 22 clamp, cut and glue the working material strip a1 and the spare material strip a2. On the one hand, a first driving member 220 and a second driving member 214 with smaller specifications can be used, which is beneficial to reducing the cost of the device while reserving more installation space for other components and reducing the difficulty of spatial layout of each component; on the other hand, it is beneficial to save the time required for the roll changing process and improve the roll changing efficiency.

[0083] Further, the roll changing device also includes a mounting plate 40, a third driving member 51 and a fourth driving member 52. The first moving plate 50a and the second moving plate 50b are both mounted on the mounting plate 40 through guide rails, so that the first moving plate 50a and the second moving plate 50b can be close to or away from each other along the first direction X1 relative to the mounting plate 40. The third driving member 51 is arranged on the mounting plate 40, and the driving end of the third driving member 51 is connected to the first moving plate 50a, so that the third driving member 51 can drive the first moving plate 50a to approach or move away from the second moving plate 50b along the first direction X1. The fourth driving member 52 is arranged on the mounting plate 40, and the driving end of the fourth driving member 52 is connected to the second moving plate 50b, so that the fourth driving member 52 can drive the second moving plate 50b to approach or move away from the first moving plate 50a along the first direction X1. Optionally, the third driving member 51 and the fourth driving member 52 can be cylinders.

[0084] Specifically in the embodiment, the roll changing device also includes a first clamping assembly 80 and a second clamping assembly 90. The first clamping assembly 80 is arranged on the downstream side of the tape connection channel. The second clamping assembly 90 is arranged on the upstream side of the tape connection channel. The first clamping assembly 80 is used to clamp the passing working tape a1, so as to prevent the downstream cut end a11 of the working tape a1 from being separated from the first adsorption seat 221 or the third adsorption seat 211 due to factors such as the tape tension after the working tape a1 is cut. The second clamping assembly 90 is used to clamp the passing spare tape a2, so as to prevent the upstream cut end a21 of the spare tape a2 from being separated from the second adsorption seat 222 or the fourth adsorption seat 212 due to factors such as the tape tension after the spare tape a2 is cut.

[0085] See also Figure 4 and Fig. 9Specifically, in the embodiment, the first clamping assembly 80 includes a moving driving member 83, a clamping driving member 84, a first clamping plate 81 and a second clamping plate 82. The moving driving member 83 is mounted on the mounting plate 40, and the clamping driving member 84 is mounted at the driving end of the moving driving member 83, so that the moving driving member 83 can drive the clamping driving member 84 to move along the second direction X2. The first clamping plate 81 and the second clamping plate 82 are mounted at the driving end of the clamping driving member 84, and the clamping driving member 84 can drive the first clamping plate 81 and the second clamping plate 82 to clamp or release each other. When the first moving plate 50a and the second moving plate 50b approach each other along the first direction X1 and drive the working material belt a1 and the spare material belt a2 passing through the belt connection channel to approach each other, the working material belt a1 is opposite to the space between the first clamping plate 81 and the second clamping plate 82 in the second direction X2 (i.e., the width direction of the working material belt a1), so that when the moving driving member 83 drives the first clamping plate 81 and the second clamping plate 82 to move close to the working material belt a1 along the second direction X2, the working material belt a1 can enter between the first clamping plate 81 and the second clamping plate 82. After the working material belt a1 enters the space between the first clamping plate 81 and the second clamping plate 82, the clamping driving member 84 drives the first clamping plate 81 and the second clamping plate 82 to approach each other and clamp the working material belt a1. Optionally, the moving driving member 83 can be a cylinder, and the clamping driving member 84 can be a clamping claw cylinder 941.

[0086] Furthermore, the first clamping plate 81 is used to clamp the working material strip a1 with its clamping surface facing the adhesive laminating mechanism 22, and the second clamping plate 82 is used to clamp the working material strip a1 with its clamping surface facing the adsorption mechanism 21. The first clamping plate 81 has a first pressing portion a5 (see Figure 4 ). When the rotating seat 225 rotates to the second state, the moving seat 229 can drive the glue sticking seat 224 to move along the first direction X1 toward the adsorption mechanism 21 to the downstream end of the glue suction surface a4 and abut against the first pressing portion a5, so that the first pressing portion a5 presses the working material strip a1 against the glue suction surface a4 to prevent the working material strip a1 from being separated from the glue suction surface a4 during the rolling process of the roller 31 of the glue rolling assembly 30.

[0087] See also Figure 4 and Fig.10 Specifically, in the embodiment, the second clamping assembly 90 includes a driving portion 93 and a clamping portion 94. The driving portion 93 is mounted on the first movable plate 50a, and the clamping portion 94 is connected to the driving end of the driving portion 93. The roll changing device also includes a limit plate 53 (see Figure 4), the driving part 93 is used to drive the clamping part 94 to move along the first direction X1 until it abuts against the limiting plate 53, so that the clamping part 94 and the spare material strip a2 are opposite to each other in the second direction X2 (i.e., the width direction of the spare material strip a2). The driving part 93 is also used to drive the clamping part 94 to move close to the spare material strip a2 along the second direction X2 until the clamping part 94 clamps the spare material strip a2. In this way, when it is necessary to clamp the spare material strip a2, the driving part 93 drives the clamping part 94 to move along the first direction X1 toward the limiting plate 53 until it abuts against the limiting plate 53. At this time, the clamping part 94 is opposite to the spare material strip a2 in the second direction X2. Then, the driving part 93 drives the clamping part 94 to move close to the spare material strip a2 along the second direction X2 until the clamping part 94 clamps the spare material strip a2.

[0088] Further, the driving part 93 includes a first cylinder 931, a first mounting block 932, a second cylinder 933 and a second mounting block 934. The first cylinder 931 is mounted on the first movable plate 50a, the first mounting block 932 is mounted on the driving end of the first cylinder 931, and the first cylinder 931 is used to drive the first mounting block 932 to move along the first direction X1. The second cylinder 933 is mounted on the first mounting block 932, the second mounting block 934 is mounted on the driving end of the second cylinder 933, and the second cylinder 933 is used to drive the second mounting block 934 to move along the second direction X2. The clamping part 94 is mounted on the second mounting block 934 to move along the first direction X1 and the second direction X2 with the second mounting block 934. Optionally, the clamping part 94 includes a clamping claw cylinder 941 and a third clamping plate 91 and a fourth clamping plate 92 mounted on the driving end of the clamping claw cylinder 941. The clamping jaw cylinder 941 is used to drive the third clamping plate 91 and the fourth clamping plate 92 to clamp or release.

[0089] Thus, when the material roll on the first unwinding assembly 10a is the working material roll A and the material roll on the second unwinding assembly 10b is the spare material roll B, the driving end of the first cylinder 931 extends out, thereby driving the second mounting block 934 to abut against the limit plate 53 on the second movable plate 50b, so that the space between the third clamping plate 91 and the fourth clamping plate 92 is opposite to the spare material strip a2 in the second direction X2; then, the driving end of the second cylinder 933 extends out, thereby driving the third clamping plate 91 and the fourth clamping plate 92 to approach the spare material strip a2 along the second direction X2 through the second mounting block 934, until the spare material strip a2 enters between the third clamping plate 91 and the fourth clamping plate 92. Then, the clamping claw cylinder 941 drives the third clamping plate 91 and the fourth clamping plate 92 to clamp the spare material strip a2.

[0090] When the material roll on the first unwinding component 10a is the spare material roll B and the material roll on the second unwinding component 10b is the working material roll A, the driving end of the first cylinder 931 does not extend. At this time, the space between the third clamping plate 91 and the fourth clamping plate 92 is already opposite to the spare material tape a2 in the second direction X2. The driving end of the second cylinder 933 extends to allow the spare material tape a2 to enter between the third clamping plate 91 and the fourth clamping plate 92, thereby enabling the clamping cylinder 941 to drive the third clamping plate 91 and the fourth clamping plate 92 to clamp the spare material tape a2.

[0091] That is, when the roll on the first unwinding assembly 10a is the spare roll B and the roll on the second unwinding assembly 10b is the working roll A, the first cylinder 931 and the limit plate 53 do not work. When the roll on the first unwinding assembly 10a is the working roll A and the roll on the second unwinding assembly 10b is the spare roll B, the first cylinder 931 and the limit plate 53 can adjust the positions of the third clamping plate 91 and the fourth clamping plate 92 in the first direction X1, so that the third clamping plate 91 and the fourth clamping plate 92 can accurately clamp the spare material tape a2 passing by.

[0092] It should be noted that, during the process of changing the rolls when the roll on the first unwinding assembly 10a is the working roll A and the roll on the second unwinding assembly 10b is the spare roll B, after the third clamping plate 91 and the fourth clamping plate 92 clamp the spare material tape a2 passing by, the second movable plate 50b can drive the third clamping plate 91 and the fourth clamping plate 92 to move through the limiting plate 53 when moving close to the first movable plate 50a along the first direction X1, thereby adjusting the position of the spare material tape a2 clamped by the third clamping plate 91 and the fourth clamping plate 92. In other words, the limiting plate 53 can also play a role in adjusting the position of the spare material tape a2.

[0093] Furthermore, the third clamping plate 91 is used to clamp the spare material tape a2 with its clamping surface facing the glue sticking mechanism 22, and the fourth clamping plate 92 is used to clamp the spare material tape a2 with its clamping surface facing the adsorption mechanism 21. The downstream end of the third clamping plate 91 has a second pressing portion a6. When the rotating seat 225 rotates to the second state, the moving seat 229 can drive the glue sticking seat 224 to move along the first direction X1 toward the adsorption mechanism 21 to the upstream end of the glue suction surface a4 to abut against the second pressing portion a6, so that the second pressing portion a6 presses the spare material tape a2 against the glue suction surface a4, preventing the spare material tape a2 from detaching from the glue suction surface a4 during the rolling process of the roller 31 of the glue rolling assembly 30.

[0094] It should be noted that the driving portion 93 of the second clamping assembly 90 is not limited to being installed on the first movable plate 50a. In other embodiments, the driving portion 93 of the second clamping assembly 90 can also be installed on the second movable plate 50b. In this case, the limit plate 53 is installed on the first movable plate 50a. As long as it can accurately clamp or release the spare material strip a2, no limitation is made here.

[0095] Based on the above-mentioned roll changing device, the utility model also provides a winding device. The winding device includes a winding device and a roll changing device as described in any of the above embodiments. The winding device is arranged downstream of the roll changing device, and is used to wind the working material strip a1 to form a battery cell. It should be noted that the working material strip and the spare material strip in this article can be a pole piece material strip. Of course, in other embodiments, the working material strip and the spare material strip can also be other types of material strips, which are not limited here.

[0096] The technical features of the above-described embodiments may be arbitrarily combined. To make the description concise, not all possible combinations of the technical features in the above-described embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0097] The above-mentioned embodiments only express several implementation methods of the utility model, and the description is relatively specific and detailed, but it cannot be understood as limiting the scope of the utility model patent. It should be pointed out that for ordinary technicians in this field, several modifications and improvements can be made without departing from the concept of the utility model, which all belong to the protection scope of the utility model. Therefore, the protection scope of the utility model patent shall be based on the attached claims.
