[0002] In the production process of lithium batteries, the positive electrode sheet, the separator and the negative electrode sheet are usually wound into an electric core. After the ear tabs are welded at specific positions on the electrode sheets, the ear tabs enter the winding device together with the electrode sheets for winding.

[0003] Generally, ear tab material rolls are used to provide ear tabs. After one ear tab material roll is used up, the next ear tab material roll needs to be replaced. In the prior art, the replacement of ear tab material rolls is usually carried out manually. The manual roll-changing method not only requires the machine to stop, reducing the production efficiency, but also consumes labor and increases the production cost of the electric core.

[0036] In the description of this specification, the description of the term "as an alternative embodiment" means that the specific features, structures, materials or characteristics described in connection with this embodiment or example are included in at least one alternative embodiment or alternative example of the present utility model. In this specification, the schematic expression of the above terms does not necessarily refer to the same embodiment or example. Moreover, the specific features, structures, materials or characteristics described can be combined in a suitable manner in any one or more embodiments or examples.

[0037] Combined Figure 1 and Figure 2 As shown, this embodiment provides an automatic tab rewinding device, including a mounting plate 10 and a tab reel assembly 20, a third clamping member 30, a cutting assembly 40, and a tab encapsulation assembly 50 provided on the mounting plate 10, wherein:

[0038] The tab material tray assembly 20 includes a first unwinding assembly 21 and a second unwinding assembly 22 for outputting the tab material strip, the first unwinding assembly 21 includes a first tab material tray 211 and a first clamping member 212, the first clamping member 212 is used to clamp the tab material strip 1 output by the first tab material tray 211, the second unwinding assembly 22 includes a second tab material tray 221 and a second clamping member 222, the second clamping member 222 is used to clamp the tab material strip 1 output by the second tab material tray 221, and the first unwinding assembly 21 and the second unwinding assembly 22 can be arranged along a first direction (i.e. Figure 1 The first clamping member 212 and the second clamping member 222 are moved in the y-axis direction so that the first clamping member 212 and the second clamping member 222 can be aligned with the third clamping member 30 respectively;

[0039] The third clamping member 30 is arranged along the second direction (ie Figure 1 The third clamping member 30 is used to clamp the tab strip 1 output from the first clamping member 212, or the third clamping member 30 is used to clamp the tab strip 1 output from the second clamping member 222;

[0040] The cutting assembly 40 is used to cut the tab strip 1 clamped between the first clamping member 212 and the third clamping member 30, or the cutting assembly 40 is used to cut the tab strip 1 clamped between the second clamping member 222 and the third clamping member 30;

[0041] The tab rubber-coated assembly 50 is used to connect the tab material strip 1 clamped by the third clamping member 30 with the tab material strip 1 clamped by the first clamping member 212 , or the tab rubber-coated assembly 50 is used to connect the tab material strip 1 clamped by the third clamping member 30 with the tab material strip 1 clamped by the second clamping member 222 .

[0042] Therefore, if the tab material strip 1 output by the first unwinding assembly 21 is used as the working material strip, and the tab material strip 1 output by the second unwinding assembly 22 is used as the spare material strip, when the tab material strip 1 is output by the first unwinding assembly 21, the first clamping member 212 is aligned with the third clamping member 30 (e.g. Figure 1 As shown), the tab material strip 1 unwound from the first tab material tray 211 is transported downstream through the first clamping member 212. When the first tab material tray 211 is used up and needs to be rewound, the first clamping member 212 and the third clamping member 30 clamp the tab material strip 1 output from the first tab material tray 211, and the cutting assembly 40 moves between the first clamping member 212 and the third clamping member 30 to cut the tab material strip 1 between the first clamping member 212 and the third clamping member 30. Subsequently, the cutting assembly 40 returns to its original position to avoid it; the second unwinding assembly 22 moves along the first direction to align the second clamping member 222 with the third clamping member 30, so that the end of the tab material strip 1 clamped by the second clamping member 222 is aligned with the end of the tab material strip 1 clamped by the third clamping member 30 (as shown in FIG. Figure 2As shown, subsequently, the tab encapsulation assembly 50 moves between the second clamping member 222 and the third clamping member 30. The tab encapsulation assembly 50 connects the tab strip 1 clamped by the third clamping member 30 with the tab strip 1 clamped by the second clamping member 222, completing the splicing of the tab strip 1. Finally, the tab encapsulation assembly 50 returns to its original position, the second clamping member 222 and the third clamping member 30 release the tab strip 1, and the tab strip 1 continues to be conveyed downstream, completing the roll change of the tab strip. During the process of the second tab reel 221 conveying the tab strip 1, the first tab reel 211 can be replaced manually or mechanically, with the first tab 211 serving as a spare strip. When the second tab reel 221 needs to be replaced after being used up, the above operation can be repeated to complete the roll change of the tab strip. The specific operation process will not be elaborated here.

[0043] The tab automatic roll change device provided in this embodiment can achieve the automatic roll change of the tab strip, not only saving labor costs, but also shortening the downtime, improving the production efficiency of the battery cell, increasing the operating rate of the tab roll change device, and reducing the production cost.

[0044] Based on the above embodiment, as an alternative embodiment, in combination with Figure 3 As shown, the tab reel assembly 20 further includes a tab reel transverse movement assembly 23 and a connecting seat. The connecting seat includes a first connecting seat 24 and a second connecting seat 25. The tab reel transverse movement assembly 23 is arranged on the mounting plate 10. The first unwinding assembly 21 and the second unwinding assembly 22 are symmetrically arranged on the first connecting seat 24 and the second connecting seat 25 along the third direction (i.e., Figure 1 the z-axis direction in ). The first connecting seat 24 and the second connecting seat 25 connect the first unwinding assembly 21 and the second unwinding assembly 22, and the first connecting seat 24 and the second connecting seat 25 are connected to the tab reel transverse movement assembly 23. The first unwinding assembly 21 and the second unwinding assembly 22 are connected together with the tab transverse movement reel assembly 23 through the first connecting seat 24 and the second connecting seat 25. The tab transverse movement reel assembly 23 is used to drive the first unwinding assembly 21 and the second unwinding assembly 22 to move along the first direction, enabling the first clamping member 212 and the second clamping member 222 to be alternately aligned with the third clamping member 30. Thus, the first unwinding assembly 21 and the second unwinding assembly 22 are symmetrically arranged on the first connecting seat 24 and the second connecting seat 25 along the third direction, which can save space and reduce the floor area of the tab automatic roll change device. By driving the first unwinding assembly 21 and the second unwinding assembly 22 to move along the first direction through the tab reel transverse movement assembly 23, it is more convenient for the first clamping member 212 and the second clamping member 222 to be alternately aligned with the third clamping member 30.

[0045] Based on the above embodiment, as an alternative embodiment, in combination with Figure 6As shown in the figure, the tab stock tray transverse movement assembly 23 includes a transverse movement mounting base 231. The transverse movement mounting base 231 is arranged on the mounting plate 10. A first slide rail 232 and a tab stock tray transverse movement driving member 233 are arranged on the transverse movement mounting base 231. The first slide rail 232 extends along a first direction. A first slide plate 234 is slidably connected to the first slide rail 232. The tab stock tray transverse movement driving member 233 can be connected to the first slide plate 234 through a coupling and a lead screw. A first connection seat 24 and a second connection seat 25 are both arranged on the first slide plate 234. The tab stock tray transverse movement driving member 233 can drive the first slide plate 234 to move along the first slide rail 232, so that the first connection seat 24 and the second connection seat 25 connected to the first slide plate 234 move along the first direction, so as to drive the first unwinding assembly 21 and the second unwinding assembly 22 to move along the first direction. As an alternative embodiment, the tab stock tray transverse movement driving member can be a motor.

[0046] On the basis of the above embodiment, as an alternative embodiment, in combination with Figure 4 and Figure 5As shown in the figure, the first unwinding assembly 21 further includes a first substrate 213, a first clamping drive member 214, and a first tab strip buffer member 215. The first substrate 213 is arranged parallel to the mounting plate 10. The first substrate 213 includes a first surface and a second surface arranged opposite to each other in the first direction. The first tab reel 211 and the first tab strip buffer member 215 are both arranged on the first surface, and the first clamping drive member 214 is arranged on the second surface. The first clamping drive member 214 is connected to the first clamping member 212. A first avoidance groove a is formed in the first substrate 213. The first clamping member 212 passes through the first substrate 213 through the first avoidance groove a and extends to the first surface to clamp the tab strip 1 output from the first tab strip buffer member 215. The first clamping drive member 214 can drive the first clamping member 212 to move in the first avoidance groove a in the second direction, so that when the first unwinding assembly 21 moves in the first direction, the first clamping member 212 can avoid the cutting assembly 40 to prevent interference between the two. When connecting the tab strip 1 clamped by the third clamping member 30 and the tab strip 1 clamped by the first clamping member 212, the first clamping member 212 can send the tab strip 1 it clamps to the gluing position, facilitating the connection of the tab strip 1. Thus, by arranging the first tab reel 211 and the first tab strip buffer member 215 on the first surface, the first clamping drive member 214 on the second surface, and the first clamping member 212 can extend to the first surface, it can be avoided that the first clamping member 212 interferes with the first tab strip buffer member 215 when moving in the second direction, and the layout of the first unwinding assembly 21 is more reasonable and compact. Among them, the first tab strip buffer member 215 includes a plurality of tab guide rollers to facilitate the running and conveying of the tab strip 1 output from the first tab reel 211. A second slide rail 216 is arranged on the second surface. The first clamping member 212 is slidably connected to the second slide rail 216. The second slide rail 216 extends in the second direction. The first clamping drive member 214 can drive the first clamping member 212 to move in the first avoidance groove a along the second slide rail 216. A feeding drive member 217 is further arranged on the second surface. The feeding drive member 217 is connected to the first tab reel 211. The feeding drive member 217 is used to drive the first tab reel 211 to unwind the tab strip 1. As an optional implementation manner, the first clamping drive member 214 can be a cylinder, and the feeding drive member 217 can be a motor.

[0047] Based on the above embodiments, as an alternative embodiment, the second unwinding assembly 22 further includes a second substrate, a second clamping driving member, and a second tab strip buffer member. The second substrate is arranged in parallel with the mounting plate 10. The second substrate includes a third surface and a fourth surface arranged opposite to each other in the first direction. The third surface is arranged opposite to the first surface. Both the second tab reel 221 and the second tab strip buffer member are arranged on the third surface, and the second clamping driving member is arranged on the fourth surface. The second clamping driving member is connected to the second clamping member 222. A second avoidance groove is formed on the second substrate. The second clamping member 222 passes through the second substrate through the second avoidance groove and extends to the third surface to clamp the tab strip 1 output from the second tab strip buffer member. The second clamping driving member can drive the second clamping member 222 to move in the second avoidance groove along the second direction. When the second unwinding assembly 22 moves along the first direction, the second clamping member 222 can avoid the cutting assembly 40 to prevent interference between the two. When connecting the tab strip 1 clamped by the third clamping member 30 and the tab strip 1 clamped by the second clamping member 222, the second clamping member 222 can send the tab strip 1 it clamps to the gluing position to facilitate connecting the tab strip 1. Thus, by arranging the third surface opposite to the first surface, the second clamping member 222 and the first clamping member 221 can be arranged opposite to each other when clamping the tab strip 1, which is beneficial to shortening the moving distance of the first unwinding assembly 21 or the second unwinding assembly 22 along the first direction and improving the efficiency of roll change. In this embodiment, the specific structure of the second unwinding assembly 22 is the same as that of the first unwinding assembly 21, and the specific structure of the second unwinding assembly 22 will not be elaborated here.

[0048] Based on the above embodiments, as an alternative embodiment, in combination with Figure 11 As shown, the third clamping member 30 is provided with a mounting hole 31. The third clamping member 30 is mounted on the mounting plate 10 through the mounting hole 31. The third clamping member 30 can be a pneumatic claw, and the third clamping member 30 can clamp or release the tab strip 1 that the tab strip 1 can pass through.

[0049] Based on the above embodiments, as an alternative embodiment, in combination with Figure 8As shown, the cutting assembly 40 includes a cutter base 41, a first cutter 42, a second cutter 43, a first pressing block 44, and a connecting block 45 disposed on the cutter base 41. The first cutter 42 is fixedly disposed on the cutter base 41. The connecting block 45 connects the second cutter 43 and the first pressing block 44. The connecting block 45 is movable along a third direction to drive the second cutter 43 and the first pressing block 44 to approach or depart from the first cutter 42 simultaneously, so that the second cutter 43 and the first cutter 42 cooperate to cut the tab strip 1 clamped by the first clamping member 212 and the third clamping member 30, or cut the tab strip 1 clamped by the second clamping member 222 and the third clamping member 30. When the second cutter 43 and the first cutter 42 cut the tab strip 1, the first pressing block 44 cooperates with the first cutter 42 to be able to press the tab strip 1, prevent the movement of the tab strip 1, and avoid the curling phenomenon at the end of the tab strip 1. Among them, the first pressing block 44 is disposed at the bottom of the cutter base 41, the first pressing block 44 can be disposed opposite to the first cutter 42, the second cutter 43 is disposed on the side of the cutter base 41, and the sides of the second cutter 43 and the first cutter 42 can cut the tab strip 1. A first elastic member 46 is disposed between the connecting block 45 and the first pressing block 44. One end of the first elastic member 46 is connected to the first pressing block 44, and the other end of the first elastic member 46 is connected to the connecting block 45. When the first pressing block 44 and the first cutter 42 cooperate to press the tab strip 1, the first elastic member 46 can generate an elastic force to provide a buffering force for the tab strip 1 pressed between the first pressing block 44 and the first cutter 42, and avoid damaging the tab strip 1.

[0050] On the basis of the above embodiment, as an alternative embodiment, the cutting assembly 40 further includes a guide rod 451, a floating joint 452, and a cutting driving member 47 disposed on the cutter base 41. One end of the connecting block 45 is connected to the guide rod 451. The guide rod 451 can be slidably connected to the cutter base 41 through a linear bearing. The guide rod 451 extends along the third direction. The other end of the connecting block 45 is connected to the cutting driving member 47 through the floating joint 452. The cutting driving member 47 drives the guide rod 451 to move relative to the cutter base 41 along the third direction by driving the floating joint 452 and the connecting block 45, so as to drive the connecting block 45 and the second cutter 43 and the first pressing block 44 disposed on the connecting block 45 to move along the third direction to approach or depart from the first cutter 42 fixedly disposed on the cutter base 41. Thus, with the above structure of the cutting assembly 40, the second cutter 43 and the first pressing block 44 can move more stably along the third direction, which is beneficial to improving the cutting quality of the tab strip 1. As an alternative embodiment, the cutting driving member 47 can be a cylinder.

[0051] Based on the above embodiments, as an alternative embodiment, the cutting assembly 40 further includes a cutting movement driving member 48. The cutting movement driving member 48 is connected to the cutter holder 41. The cutting movement driving member 48 is used to drive the cutter holder 41 to move in the first direction. Thus, the cutting movement driving member 48 can drive the cutter holder 41 to reach between the first clamping member 212 and the third clamping member 30 to cut the tab strip 1 clamped by the first clamping member 212 and the third clamping member 30, or drive the cutter holder 41 to reach between the second clamping member 222 and the third clamping member 30 to cut the tab strip 1 clamped by the second clamping member 222 and the third clamping member 30. The cutting movement driving member 48 can also drive the cutter holder 41 away from the tab strip 1 to avoid interfering with the running of the tab strip 1. Specifically, the cutting assembly 40 further includes a cutting mounting seat. A second slide rail and the cutting movement driving member 48 are arranged on the cutting mounting seat. The second slide rail extends in the first direction. The second slide plate is slidably connected to the second slide rail. The cutting movement driving member 48 is connected to the second slide plate. The cutter holder 41 is arranged on the second slide plate. The cutting movement driving member 48 can drive the second slide plate to move along the second slide rail, so that the cutter holder 41 moves in the first direction to drive each component on the cutter holder 41 to move in the first direction. As an alternative embodiment, the cutting movement driving member 48 can be a cylinder.

[0052] Based on the above embodiments, as an alternative embodiment, in combination Figure 7 As shown, the cutting assembly 40 and the tab pasting assembly 50 are respectively arranged on opposite sides of the mounting plate 10. Thus, the cutting assembly 40 and the tab pasting assembly 50 can move independently in the first direction, and they do not interfere with each other during the movement, which is beneficial to improving the efficiency of automatic tab roll change.

[0053] Based on the above embodiments, as an alternative embodiment, in combination Figure 9As shown, the tab glue-packing assembly 50 includes a glue-applying base 51, a tab glue-applying platform 52, a glue-rolling wheel 53, and a second pressing block 54 disposed on the glue-applying base 51. The tab glue-applying platform 52 is used to carry the end of the tab strip 1 clamped by the third clamping member 30 and the end of the tab strip 1 clamped by the first clamping member 212. The second pressing block 54 is used to fix the end of the tab strip 1 clamped by the third clamping member 30 and the end of the tab strip 1 clamped by the first clamping member 212 on the tab glue-applying platform 52. The glue-rolling wheel 53 can roll back and forth between the end of the tab strip 1 clamped by the third clamping member 30 and the end of the tab strip 1 clamped by the first clamping member 212 to connect the end of the tab strip 1 clamped by the third clamping member 30 and the end of the tab strip 1 clamped by the first clamping member 212 with adhesive tape. Alternatively, the tab glue-applying platform 52 is used to carry the end of the tab strip 1 clamped by the third clamping member 30 and the end of the tab strip 1 clamped by the second clamping member 222. The second pressing block 54 is used to fix the end of the tab strip 1 clamped by the third clamping member 30 and the end of the tab strip 1 clamped by the second clamping member 222 on the tab glue-applying platform 52. The glue-rolling wheel 53 can roll back and forth between the end of the tab strip 1 clamped by the third clamping member 30 and the end of the tab strip 1 clamped by the second clamping member 222 to connect the end of the tab strip 1 clamped by the third clamping member 30 and the end of the tab strip 1 clamped by the second clamping member 222 with adhesive tape. Thus, by pressing the ends of the two tab strips 1 against the tab glue-applying platform 52 with the second pressing block 54, the movement of the ends of the tab strip 1 can be avoided, which may affect the quality of glue application. By rolling the glue-rolling wheel 52 back and forth between the ends of the two tab strips 1, better connection of the two tab strips 1 can be ensured, and the stability of their connection can be guaranteed.

[0054] On the basis of the above embodiment, as an alternative embodiment, a glue-wheel frame 55 is further disposed on the glue-applying base 51. The glue-wheel frame 55 is L-shaped. The glue-rolling wheel 53 is disposed on the glue-wheel frame 55 through a connecting arm. A second elastic member (not shown in the figure) is disposed between the glue-wheel frame 55 and the connecting arm. One end of the second elastic member abuts against the inner wall of the glue-wheel frame 55, and the other end of the second elastic member abuts against the connecting arm. The second elastic member can provide elastic force for the glue-rolling wheel 53 through the connecting arm, so that the glue-rolling wheel 53 can be fixed within the glue-wheel frame 55.

[0055] Based on the above embodiments, as an alternative embodiment, the tab encapsulation assembly 50 further includes a glue rolling driving member 56 and a second pressing block driving member 57 disposed on the glue sticking base 51. The glue rolling driving member 56 is connected to the glue rolling wheel 53 through a glue wheel frame 55. The glue rolling driving member 56 is configured to drive the glue rolling wheel 53 to move in a first direction, so that the glue rolling wheel drives the adhesive tape to bond the ends of the two tab strips 1, thereby connecting the two tab strips 1 together through the adhesive tape. The second pressing block driving member 57 is connected to the second pressing block 54. The second pressing block driving member 54 is configured to drive the second pressing block 54 to move in a third direction, so that the second pressing block 54 approaches or departs from the tab glue sticking platform 51. Thus, when the second pressing block 54 approaches the tab glue sticking platform 51, the ends of the two tab strips 1 can be pressed against the tab glue sticking platform 51. As an alternative embodiment, both the glue rolling driving member 56 and the second pressing block driving member 57 can be cylinders.

[0056] Based on the above embodiments, as an alternative embodiment, the tab encapsulation assembly 50 further includes a glue sticking movement driving member 58. The glue sticking movement driving member 58 is connected to the glue sticking base 51. The glue sticking movement driving member 58 is configured to drive the glue sticking base 51 to move in a first direction, so that the tab glue sticking platform 52 approaches or departs from the glue sticking position. Thus, when glue needs to be stuck between the ends of the two tab strips 1, the tab glue sticking platform 52 is moved between the ends of the two tab strips 1 for glue sticking. After the glue sticking between the ends of the two tab strips 1 is completed, the glue sticking base 1 is moved away from the tab strips 1 to avoid interfering with the tape running of the tab strips 1.

[0057] Based on the above embodiments, as an alternative embodiment, the tab encapsulation assembly 50 further includes a glue sticking mounting base. A third slide rail and a glue sticking movement driving member 58 are disposed on the glue sticking mounting base. The third slide rail extends in the first direction. The glue sticking base 51 is slidably connected to the third slide rail. The glue sticking movement driving member 58 is connected to the glue sticking base 51. The glue sticking movement driving member 58 can drive the glue sticking base 51 to move along the third slide rail, so that the glue sticking base 51 moves in the first direction to drive each component on the glue sticking base 51 to move in the first direction. As an alternative embodiment, the glue sticking movement driving member 58 can be a cylinder.

[0058] Based on the above embodiments, as an alternative embodiment, in combination Figure 10As shown in the figure, the tab sticking platform 52 includes an adsorption area 521 and auxiliary areas 522 arranged on both sides of the adsorption area 521. The adsorption area 521 and the two auxiliary areas 522 are arranged along the second direction. The adsorption area 521 adsorbs the adhesive tape through negative pressure, and the auxiliary areas 522 blow up the adhesive tape through positive pressure, so that the adhesive tape wraps around the ends of the two tab tapes 1. The auxiliary areas 522 can assist the glue rolling wheel 53 to bond the adhesive tape to the ends of the two tab tapes 1. A plurality of through holes are provided in both the adsorption area 521 and the auxiliary areas 522. Thus, the tab sticking platform with the above structure can better bond the ends of the two tab tapes 1 and improve the stability of the connection between the two tab tapes 1.
