The technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the drawings in the embodiments of the present application, and it is obvious that the described embodiments are only a part of the embodiments of the present application, and not all of the embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present application.

Referring to fig. 1-10, the present application discloses an encapsulating apparatus for encapsulating a battery cell 10, comprising: an unwinding mechanism 100 for releasing the adhesive tape 1; the traction mechanism 200 is arranged at the downstream of the unwinding mechanism 100 and can pull out the adhesive tape 1 in the unwinding mechanism 100; the battery cell supporting mechanism 300 is arranged downstream of the unwinding mechanism 100 and upstream of the traction mechanism 200 and is used for supporting the battery cell 10; the turnover mechanism 400 is arranged outside the cell support mechanism 300, and is capable of extracting the cell 10 on the cell support mechanism 300 and driving the cell 10 to turn over; the pulling mechanism 200 pulls out the adhesive tape 1 from the unwinding mechanism 100, and pulls the adhesive tape 1 through the cell support mechanism 300, so that the adhesive tape 1 is conveniently stuck to the surface of the cell 10 on the cell support mechanism 300; after the adhesive tape 1 coats the upper surface 11 of the battery cell 10, the turnover mechanism 400 extracts the battery cell 10 and drives the battery cell 10 to rotate, so that the side surface 12 of the battery cell 10 adjacent to the upper surface 11 is close to the adhesive tape 1 … …

With specific reference to fig. 1 and 2, a material roll formed by the adhesive tape 1 is wound on an unwinding shaft of the unwinding mechanism 100; when the traction mechanism 200 pulls the adhesive tape 1, the free end of the adhesive tape 1 is pulled, and the adhesive tape 1 is pulled towards the battery cell supporting mechanism 300; at the same time, the unwinding shaft rotates to release the adhesive tape 1, so that the pulling mechanism 200 pulls the adhesive tape 1 through the electric core supporting mechanism 300. The battery cell 10 to be encapsulated is placed on the battery cell supporting mechanism 300, the upper surface 11 of the battery cell 10 faces the adhesive surface of the adhesive tape 1, and the traction mechanism 200 pulls out the adhesive tape 1, so that the adhesive surface of the adhesive tape 1 is attached to the upper surface 11 of the battery cell 10. Subsequently, the turnover mechanism 400 extracts the battery cell 10 and drives the battery cell 10 to rotate, so that the side surface 12 of the battery cell 10 adjacent to the upper surface 11 is close to the adhesive surface of the adhesive tape 1, so that the adhesive tape 1 covers the side surface 12 of the battery cell 10. Then, the turnover mechanism 400 can further drive the battery cell 10 to rotate, so that the battery cell 10 abuts against the side surface 12 and the lower surface 13 opposite to the upper surface 11 is close to the adhesive surface of the adhesive tape 1, so that the adhesive tape 1 covers the lower surface 13 … … of the battery cell 10, thereby realizing multi-surface encapsulation of the battery cell 10.

Wherein, for making things convenient for drive mechanism 200 to pull sticky tape 1 through electric core supporting mechanism 300, draw sticky tape 1 in-process, drive mechanism 200 can be in electric core supporting mechanism 300 top, in order to avoid electric core supporting mechanism 300, finally pull sticky tape 1 to the position that waits to encapsulate with electric core 10 and correspond. After the adhesive tape 1 is in place, the traction mechanism 200 can descend to attach the adhesive tape 1 to the battery cell 10; alternatively, after the adhesive tape 1 is in place, the cell support mechanism 300 may be lifted, so that the cell 10 is attached to the adhesive tape 1.

In order to ensure that the adhesive tape 1 is stably attached to the surface of the battery cell 10, the encapsulation device provided by the application further comprises a smoothing mechanism 700; the smoothing mechanism 700 includes: a smoothing member 710 disposed above the cell support mechanism 300; a smoothing driving assembly 720 connected with the smoothing member 710; wherein, the flattening drive assembly 720 can drive the flattening piece 710 to approach the cell support mechanism 300 to flatten the adhesive tape 1 on the cell 10.

Specifically, in an initial state, the smoothing member 710 faces the battery cell 10 to be encapsulated supported by the battery cell support mechanism 300 and hangs above the battery cell 10, and after the traction mechanism 200 pulls the adhesive tape 1 to an initial position of the battery cell 10 to be encapsulated, the smoothing drive assembly 720 drives the smoothing member 710 to descend and abut against the battery cell 10, so as to press the adhesive tape 1 on the surface of the battery cell 10. Before the turning mechanism 400 acts, the smoothing driving assembly 720 drives the smoothing member 710 to ascend and keep away from the battery cell 10, so that the turning mechanism 400 drives the battery cell 10 to turn over.

In an embodiment, the smoothing member 710 may be a pressing block larger than the surface of the battery cell 10; in this manner, when the flattening driving assembly 720 drives the flattening member 710 against the battery cell 10, the flattening member 710 can directly flatten the adhesive tape 1 on the entire surface of the battery cell 10.

In yet another embodiment, referring to fig. 3, the smoothing member 710 may be a pressure roller; at this time, the flattening driving assembly 720 may drive the flattening member 710 to press the adhesive tape 1 against the battery cell 10 to press the adhesive tape 1 onto the surface of the battery cell 10, and may also drive the flattening member 710 to move along the surface of the battery cell 10 to flatten the adhesive tape 1 on the surface of the battery cell 10.

Specifically, the smoothing drive assembly 720 includes: a first smoothing driving assembly 721 connected to the smoothing member 710 and capable of driving the smoothing member 710 to approach or separate from the cell supporting mechanism 300; the second flattening driving assembly 722 is connected with the flattening piece 710 and can drive the flattening piece 710 to move along the surface of the battery cell 10; wherein the smoothing member 710 may be disposed at an output end of the first smoothing driving assembly 721, and a main body of the first smoothing driving assembly 721 is disposed at an output end of the second smoothing driving assembly 722; alternatively, the smoothing member 710 may be provided at the output of the second smoothing drive assembly 722, and the main body of the second smoothing drive assembly 722 may be provided at the output of the first smoothing drive assembly 721.

In this embodiment, first smoothing drive assembly 721 may drive smoothing member 710 in a vertical direction, while second smoothing drive assembly 722 may drive smoothing member 710 in a horizontal direction. Thus, after the traction mechanism 200 pulls the tape 1 to the position, the first smoothing driving component 721 drives the smoothing component 710 to press down, and presses the tape 1 against the upper surface 11 of the battery cell. At this time, the smoothing member 710 is pressed against the initial position of the battery cell 10 to be encapsulated. Subsequently, the second leveling drive assembly 722 drives the leveling member 710 to move along the upper surface 11 toward the side surface 12, so as to gradually level the adhesive tape 1 on the surface of the battery cell 10.

Through smoothing piece 710 and setting up to the compression roller, when the drive is smoothed piece 710 and is followed electric core 10 surface motion, the compression roller can rely on the roller rotation, smooths, compresses tightly sticky tape 1 in the stationary motion. Further, by arranging the smoothing member 710 to move along the surface of the battery cell 10, the adhesive tape 1 and the battery cell 1 can be better attached.

The leveling drive assembly 720, or the first leveling drive assembly 721 and the second leveling drive assembly 722 may adopt drive members such as an electric cylinder and a linear module.

The pulling mechanism 200 includes: the first traction assembly 210 and the second traction assembly 220 are arranged at intervals along the width direction of the adhesive tape 1, and can respectively extract one end of the adhesive tape 1; and the traction driving assembly 230 is connected with the first traction assembly 210 and the second traction assembly 220 and can drive the first traction assembly 210 and the second traction assembly 220 to approach the unwinding mechanism 100 to extract the adhesive tape 1 and pull the adhesive tape 1 towards the cell support mechanism 300.

The first pulling assembly 210 and the second pulling assembly 220 can adopt a gripping jaw, a suction cup or other extracting member, and can extract the free end of the adhesive tape 1, so that the first pulling assembly 210 and the second pulling assembly 220 carry the adhesive tape 1 to move forwards under the driving of the pulling driving assembly 230.

In an embodiment, the traction drive assembly 230 may only include the first traction drive assembly 231, and the first traction assembly 210 and the second traction assembly 220 are both disposed at an output end of the first traction drive assembly 231 and can be driven by the first traction drive assembly 231 to move between the unwinding mechanism 100 and the cell support mechanism 300. The first traction drive assembly 231 may employ a drive member such as an electric cylinder, a linear module, or the like.

In this embodiment, the first traction driving assembly 231 is configured to drive the first traction assembly 210 and the second traction assembly 220 to pull the adhesive tape 1 out of the unwinding mechanism 100, and pull the adhesive tape 1 to an initial position directly facing the battery cell 10 to be encapsulated; at this time, the adhesive tape 1 is located above the battery cell 10; the leveling drive assembly 720 drives the leveling member 710 against the battery cell 10, pressing the adhesive tape 1 onto the battery cell 10.

In yet another embodiment, referring to fig. 4, the traction drive assembly 230 may include only a first traction drive assembly 231 and a second traction drive assembly 232; the first traction driving assembly 231 is connected with and drives the first traction assembly 210 and the second traction assembly 220 to move between the unwinding mechanism 100 and the cell supporting mechanism 300 along the horizontal direction, so as to facilitate the traction of the adhesive tape 1 to a position to be encapsulated; the second traction drive assembly 232 is connected with and drives the first traction assembly 210 and the second traction assembly 220 to move in the vertical direction, so as to apply the adhesive tape 1 to the surface of the battery cell 10. Wherein the first traction assembly 210 and the second traction assembly 220 may be provided at the output of the first traction drive assembly 231, while the body of the first traction drive assembly 231 is provided at the output of the second traction drive assembly 232; alternatively, the first traction assembly 210 and the second traction assembly 220 may be provided at the output of the second traction drive assembly 232, with the body of the second traction drive assembly 232 being provided at the output of the first traction drive assembly 231.

In this embodiment, the first traction driving assembly 231 is configured to drive the first traction assembly 210 and the second traction assembly 220 to pull the adhesive tape 1 out of the unwinding mechanism 100, and pull the adhesive tape 1 to an initial position directly facing the battery cell 10 to be encapsulated; at this time, the adhesive tape 1 is located above the battery cell 10; subsequently, the second traction drive assembly 232 drives the first traction assembly 210 and the second traction assembly 220 to pull the adhesive tape 1 towards the cell upper surface 11, so that the adhesive tape 1 is stuck on the cell 10; subsequently, the smoothing driving assembly 720 drives the smoothing member 710 against the battery cell 10 to better smooth the adhesive tape 1 along the surface of the battery cell 10.

By arranging the second traction driving assembly 232, the adhesive tape 1 can be pre-attached to the battery cell 1 after the adhesive tape 1 is pulled out; therefore, the condition that the leveling member 710 presses down the suspended adhesive tape 1 to pull the adhesive tape 1 out of the first traction assembly 210 and the second traction assembly 220, thereby causing the free end of the adhesive tape 1 to deform, can be avoided.

The first traction drive assembly 231 and the second traction drive assembly 232 may adopt drive members such as an electric cylinder and a linear module.

It is easy to understand, sticky tape 1 has certain width, in order to avoid sticky tape 1 to buckle or distort, before sticky tape 1 is pasted on electric core 10, can follow its width direction, and tensile sticky tape 1 once guarantees that sticky tape 1 expandes completely, and then improves the effect of rubberizing. To this end, the traction mechanism 200 further includes a pre-tensioning assembly 240, and the pre-tensioning assembly 240 connects the first traction assembly 210 and the second traction assembly 220 and is capable of driving the first traction assembly 210 and the second traction assembly 220 toward or away from each other.

Specifically, the pre-tensioning assembly 240 includes: the pre-stretching guide 241 extends along the width direction of the adhesive tape 1, and the first traction assembly 210 and/or the second traction assembly 220 are/is connected with the pre-stretching guide 241 in a sliding way; a pre-tensioning drive 242 capable of driving the first traction assembly 210 and the second traction assembly 220 to move relative to each other; wherein, after the first pulling member 210 and the second pulling member 220 clamp the adhesive tape 1, the pre-stretching driving element 242 can drive the first pulling member 210 and/or the second pulling member 220 to move away from each other along the pre-stretching guide 241, thereby stretching the adhesive tape 1.

With particular reference to fig. 4, at least one of the first pulling member 210 and the second pulling member 220 is slidably connected to the pre-tensioning guide 241 and can be driven by the pre-tensioning driving element 242 to move away from the other pulling member to stretch the adhesive tape 1. In order to reduce the movement stroke of the pulling assembly and speed up the stretching action, the first pulling assembly 210 and the second pulling assembly 220 may be slidably connected to the pre-stretching guide 241; the pre-tensioning driving element 242 may be provided in two parts, which are respectively connected to the first traction assembly 210 and the second traction assembly 220 to drive the relative movement therebetween; in this way, after the first pulling assembly 210 and the second pulling assembly 220 extract the adhesive tape 1 and before the adhesive tape 1 is attached to the battery cell 10, the two pre-stretching driving members 242 are operated to drive the corresponding clamping jaws 110 away from each other, so as to stretch the adhesive tape 1, and the adhesive tape 1 is completely unfolded. Alternatively, the pretensioning drive member 242 may be a pneumatic claw, with the first traction assembly 210 and the second traction assembly 220 each being disposed at an output end of the pneumatic claw; in this way, after the first traction assembly 210 and the second traction assembly 220 extract the adhesive tape 1 and before the adhesive tape 1 is attached to the battery cell 10, the pre-stretching driving member 242 can simultaneously drive the first traction assembly 210 and the second traction assembly 220 to move away from each other, so as to stretch the adhesive tape 1.

The pre-stretching guide 241 may be a guide member such as a guide rail or a guide rod, and the pre-stretching driving element 242 may be a linear driving member such as an air cylinder or an electric cylinder.

In the encapsulation process, when the battery cell 10 is turned over by using the turning mechanism 400, the turning mechanism 400 needs to clamp the first end and/or the second end of the battery cell 10. The so-called first end portion and second end portion are two ends of the battery cell 10 corresponding to the width direction of the adhesive tape 1; for example, referring to fig. 1, a vertically upward surface of the battery cell 1 in the drawing is an upper surface 11; the vertically downward surface opposite to the upper surface 11 is a lower surface 13; a side surface 12 horizontally left adjacent to both the upper surface 11 and the lower surface 13; and the first end portion and the second end portion are front and rear ends which are perpendicular to the paper surface and abut on the upper surface 11, the side surface 12 and the lower surface 13. Since the adhesive tape 1 is gradually stuck to the upper surface 11, and further to the side surface 12 and the lower surface 13 from right to left; when the encapsulation of the upper surface 11 is finished, the turnover mechanism 400 clamps the first end and/or the second end of the battery cell 10, and turns over the battery cell 10 so that the side surface 12 faces the adhesive tape 1, and at this time, the turnover mechanism 400 does not affect the encapsulation of the side surface 12.

Specifically, turnover mechanism 400 includes: the cell 10 can be extracted by turning over the extraction member 410; and a reverse driving member 420 connected to the reverse extraction member 410 and capable of driving the reverse extraction member 410 to rotate.

Wherein, the turning extraction part 410 can adopt extraction components such as a sucker, a clamp and the like; the tumble drive 420 may employ a rotary drive member such as a motor.

After the encapsulation of the upper surface 11 is finished, the cell 10 on the cell supporting mechanism 300 is extracted by the turnover extracting element 410, and the turnover driving element 420 further drives the turnover extracting element 410 to drive the cell 10 to rotate.

In an embodiment, a portion of the first end and/or the second end of the battery cell 10 protrudes out of the battery cell supporting mechanism 300, and at this time, the turning and extracting element 410 does not need to avoid a position, and can directly extract the protruding portion of the battery cell 10. However, during encapsulation, the whole battery cell 10 should be supported on the battery cell support mechanism 300, so that when the flattening member 710 flattens the adhesive tape 1, the battery cell 10 is stable in position, and the adhesive tape 1 can be firmly pressed and flattened on the battery cell 10. For this purpose, referring to fig. 5, the turnover mechanism 400 further includes a turnover avoiding driving assembly 430, which is connected to the turnover extracting member 410 and can drive the turnover extracting member 410 to move closer to or away from the cell supporting mechanism 300.

The overturning extraction component 410 is arranged at the output end of the overturning driving component 420, and the main body of the overturning driving component 420 is arranged at the output end of the overturning avoiding driving component 430; alternatively, the reverse extraction element 410 is disposed at the output end of the reverse avoiding driving element 430, and the main body of the reverse avoiding driving element 430 is disposed at the output end of the reverse driving element 420.

At this time, the turning extracting element 410 may be disposed at the output end of the turning driving element 420, and the main body of the turning driving element 420 is disposed at the output end of the turning avoiding driving assembly 430; alternatively, the roll-over extractor 410 may be disposed at the output of the roll-over avoiding driving assembly 430, and the body of the roll-over avoiding driving assembly 430 is disposed at the output of the roll-over driver 420. The driving assembly 430 may be a driving member of a cylinder, an electric cylinder, or a linear module.

Specifically, the battery cell 10 is integrally supported on the battery cell support mechanism 300, and when the battery cell is not turned over, the turning extraction member 410 is away from the battery cell support mechanism 300, so as to facilitate loading and unloading of the battery cell 10 and coating of the adhesive tape 1. After the encapsulation of the upper surface 11 is finished, the overturning and avoiding driving assembly 430 drives the overturning and extracting member 410 to approach the cell supporting mechanism 300, so that the overturning and extracting member 410 extracts the cell 10; after the cell 10 is extracted by the turning extraction element 410, the turning driving element 420 further drives the turning extraction element 410 to rotate the cell 10. After the turning is finished, the cell 10 is released by the turning extraction component 410, and the turning avoidance driving component 430 drives the turning extraction component 410 to be away from the cell support mechanism 300, so as to facilitate the continuous encapsulation and blanking of the cell 10.

Further, in order to stably overturn the battery cell 10, the encapsulation device provided by the application includes two sets of turnover mechanisms 400, and two sets of turnover mechanisms 400 are arranged on two sides of the battery cell supporting mechanism 300 along the width direction of the adhesive tape 1, and can extract two ends of the battery cell 10, so as to drive the battery cell 10 to rotate stably.

For example, the inverted extraction member 410 may employ a jig; when extracting electric core 10, two sets of anchor clamps can clip the first end and the second end of electric core 10 respectively, and then rotate electric core 10 steadily. Alternatively, the two sets of the turning extractors 410 may also be matched to form a fixture, for example, the turning extractors 410 may be clamping plates, and the two clamping plates are disposed on two sides of the cell supporting mechanism 300, opposite to the first end and the second end of the cell 10; when needing rotatory electric core 10, the upset is kept away two splint relative motion of position drive assembly 430 drive for one of them splint support the first end of electric core 10, and another splint support the second end of electric core 10, and then the cooperation is carried electric core 10, so that upset driving piece 420 further drives upset extraction piece 410, drives electric core 10 and rotates.

Further, the encapsulation apparatus provided by the present application further comprises a lifting mechanism 390; the lifting mechanism 390 is connected to the cell support mechanism 300, and after the cell 10 is extracted by the turnover mechanism 400, the lifting mechanism 390 can drive the cell support mechanism 300 to descend, so that the cell 10 is separated from the cell support mechanism 300 and turned over; or, the lifting mechanism 390 is connected to the turning mechanism 400, and after the cell 10 is extracted by the turning mechanism 400, the lifting mechanism 390 can drive the turning mechanism 400 to ascend, so that the cell 10 is separated from the cell supporting mechanism 300 and turned over.

It is easy to understand that, on the electric core supporting mechanism 300 is arranged in to electric core 10, during the upset, the space of electric core 10 motion needs to be left, and mutual interference between electric core 10 and electric core supporting mechanism 300 is avoided. At this time, the lifting mechanism 390 is provided, the driving turnover mechanism 400 drives the battery cell 10 to ascend, or the driving battery cell supporting mechanism 300 descends, or the driving turnover mechanism 400 drives the battery cell supporting mechanism 300 to descend while driving the battery cell 10 to ascend, so that the battery cell 10 is separated from the battery cell supporting mechanism 300, and a space for the battery cell 10 to overturn exists between the battery cell 10 and the battery cell supporting mechanism 300.

At this time, the lifting mechanism 390 may adopt a driving member such as an electric cylinder or a linear module, and may drive the turnover mechanism 400 or the cell support mechanism 300 connected thereto to move in the vertical direction.

In addition, when the whole bearing of electric core 10 is on electric core supporting mechanism 300, for conveniently overturning extraction piece 410 to extract electric core 109 from electric core supporting mechanism 300, referring to fig. 6 to 8, electric core supporting mechanism 300 includes: the supporting platform 310 is used for supporting the middle part of the battery cell 10; the first platform 320 is arranged on one side of the support platform 310 and can support a first part of the battery cell 10; the second platform 330 is arranged on the other side of the supporting platform 310 and can support a second part of the battery cell 10; a platform driving assembly 340 connected to the first platform 320 and the second platform 330 and capable of driving the first platform 320 and the second platform 330 to move in a vertical direction; the platform driving assembly 340 can drive the first platform 320 and the second platform 330 to ascend until the surfaces of the first platform 320 and the second platform 330, which are used for supporting the battery cell 10, are coplanar with the surfaces of the supporting platform 310, which are used for supporting the battery cell 10, so that the first platform 320, the second platform 330 and the supporting platform 310 cooperate to support the whole battery cell 10; the platform driving assembly 340 can also drive the first platform 320 and the second platform 330 to descend, so that the first portion and the second portion of the battery cell 10 lose support.

Specifically, for the cell support mechanism 300, the support platform 310 is relatively fixed, and can hold the cell 10 all the time; meanwhile, because the supporting platform 310 holds the middle part of the battery cell 10, after the two ends of the battery cell 10 are separated from the supports of the first platform 320 and the second platform 330, the two ends can be held by the supporting platform 310 and cannot fall off.

The first portion and the second portion of the battery cell 10 are portions at two ends of the battery cell 10, corresponding to the first end and the second end of the battery cell 10.

In one embodiment, the inverted extractor 410 is a jig. After the battery cell upper surface 11 is coated with the adhesive, the platform driving assembly 340 drives the first platform 320 and the second platform 330 to descend, so that the first portion and the second portion of the battery cell 10 are separated from the first platform 320 and the second platform 330, so that the clamp can be inserted between the battery cell 10 and the battery cell supporting mechanism 300. At this time, one of the clamping plates of the clamp faces the upper surface 11 of the battery cell 10, and the other clamping plate is inserted between the battery cell 10 and the cell support mechanism 300 and faces the lower surface 13 of the battery cell 10, and the two clamping plates move toward each other to clamp the battery cell 10. After the battery cell 10 is turned over, the turning and extracting component 410 releases the battery cell 10, so that the battery cell 10 returns to the supporting platform 310, and at this time, the platform driving component 340 can drive the first platform 320 and the second platform 330 to ascend to support the whole battery cell 10, thereby facilitating encapsulation of a new surface.

It is easily conceived that the platform driving assembly 340 may simultaneously connect the first platform 320 and the second platform 330 to simultaneously drive the first platform 320 and the second platform 330 to move in the vertical direction, support the battery cell 10, or release the support of the end of the battery cell 10. Alternatively, the platform driving assembly 340 may employ two sets of driving members, which are respectively connected to the first platform 320 and the second platform 330, to respectively drive the first platform 320 and the second platform 330 to move in the vertical direction according to the extraction requirement of the turnover extracting member 410.

The platform driving assembly 340 may adopt a driving member such as an air cylinder, an electric cylinder, etc.

To define the moving direction of the first platform 320 and the second platform 330 and ensure that the platform driving assembly 340 can also return the first platform 320 and the second platform 330 to the initial position after driving the first platform 320 and the second platform 330 away from the initial position, in one embodiment, a guiding member, such as a guide rod or a guide rail, may be further provided; the first platform 320 and the second platform 330 are slidably disposed on the guide.

In another embodiment, the support platform 310 has a convex portion on a side thereof adjacent to the first platform 320, the first platform 320 has a concave portion at a position corresponding to the convex portion, and the convex portion extends into the concave portion; when the platform driving assembly 340 drives the first platform 320 to move along the vertical direction, the concave portion moves along the convex portion, and the movement direction of the first platform 320 is defined by the cooperation of the concave portion and the convex portion.

With particular reference to fig. 6 and 8, the support platform 310 and the first platform 320 have a thickness such that when the male portion is inserted into the female portion, the support platform 310 and the first platform 320 have multiple sides that fit against each other. In this way, when the platform driving assembly 340 drives the first platform 320 to move in the vertical direction, the convex portion and the concave portion are guided to each other, so that the first platform 320 can only move in the extending direction of the thickness of the convex portion, that is, in the vertical direction, thereby ensuring the stability of the movement of the first platform 320.

Similarly, one side of the support platform 310 close to the second platform 330 has a convex portion, the second platform 330 has a concave portion at a position corresponding to the convex portion, and the convex portion extends into the concave portion; when the platform driving assembly 340 drives the second platform 330 to move along the vertical direction, the concave portion moves along the convex portion, and the movement direction of the second platform 330 is defined by the cooperation of the concave portion and the convex portion.

The guiding engagement of the support platform 310 and the second platform 330 is similar to the guiding engagement of the support platform 310 and the first platform 320, and is not described in detail herein.

Further, the cell support mechanism 300 further includes a bottom plate 370: the bottom plate 370 is fixedly disposed opposite to the support platform 310; the bottom plate 370 has a protruding catch portion thereon; the first platform 320 and the second platform 330 have recessed card slot portions on their sides facing the backplane board 370; the platform driving assembly 340 drives the first platform 320 and the second platform 330 to descend, so that the card slot portion gradually approaches the card slot portion, and the card slot portion sinks into the card slot portion, thereby further limiting the positions of the first platform 320 and the second platform 330.

By providing the base plate 370, it is possible to define the moving path of the first platform 320 and the second platform 330, the platform driving assembly 340 drives the first platform 320 and the second platform 330 to descend, and finally, the first platform 320 and the second platform 330 will abut against the base plate 370, and the base plate 370 blocks the first platform 320 and the second platform 330, so that they cannot descend further. In addition, the movement directions of the first platform 320 and the second platform 330 can be further limited by the clamping block part and the clamping groove part which are in inserted connection and matched, so that the stability of the movement of the first platform 320 and the second platform 330 along the vertical direction is ensured, and the stable operation of the equipment is ensured.

Further, the cell support mechanism 300 further includes a fixing assembly 360, and the fixing assembly 360 is disposed outside the support platform 310 and can define the position of the cell 10.

It is easy to understand that after the battery cells 10 are loaded, the position where each battery cell 10 is inserted into the battery cell supporting mechanism 300 needs to be ensured to be fixed, so as to ensure the accuracy of encapsulation. At this moment, fixed subassembly 360 can adopt the fixed block, and the fixed block encloses and establishes into the semi-enclosed frame that only can the holding electricity core 10, and then prescribes a limit to the position of electricity core 10. Alternatively, the fixing assembly 360 may also employ a suction cup, which can suck the battery cell 10 and further define the position of the battery cell 10. Alternatively, the fixing assembly 360 may employ a clamp, and after the battery cell 10 is inserted into the battery cell supporting mechanism 300, the clamp clamps the battery cell 10, so as to define the position of the battery cell 10.

Still alternatively, the fixing member 360 includes: a fixing member 361 fixedly disposed at one side of the support platform 310; a movable member 362 disposed at the other side of the supporting platform 310 opposite to the fixed member 361; and a fixed driving member 363 coupled to the movable member 362 and capable of driving the movable member 362 toward or away from the fixed member 361.

After the battery cell 10 is placed in the battery cell support mechanism 300, the fixed driving member 363 drives the movable member 362 to abut against the battery cell 10, and finally, the battery cell 10 is pressed between the fixed member 361 and the movable member 362. At this time, the fixing member 361 is equivalent to the reference position, and when one side of the battery cell 10 abuts against the fixing member 361, the battery cell 10 is ensured to be at the fixed position in the battery cell supporting mechanism 300.

Further, a flexible member 364 is disposed on one surface of the fixed member 361 and/or the movable member 362 abutting against the battery cell 10.

Specifically, the flexible member 364 may be made of a flexible material such as polyurethane, rubber, etc. By pressing the flexible member 364 against the battery cell 10, the battery cell 10 can be prevented from being damaged by pressure when the fixed member 361 or the movable member 362 made of a rigid material continuously presses against the battery cell 10. Meanwhile, because the flexible piece 364 has a certain deformation amount, when the fixed driving piece 363 continuously drives the movable piece 362 to press the electric core 10 to compress the electric core 10, the flexible piece 364 is compressed, thereby compensating for the redundant stroke output by the fixed driving piece 363; meanwhile, the flexible member 364 has elastic restoring force and can act on the battery cell 10 in a reverse direction, so as to ensure that the fixing member 361 and the movable member 362 compress the battery cell 10.

Further, the encapsulation device further comprises a translation mechanism 380; the translation mechanism 380 is connected to the cell supporting mechanism 300 and can drive the cell supporting mechanism 300 to approach or be away from the turnover mechanism 400, so as to facilitate loading and unloading of the cell 10 on the cell supporting mechanism 300.

It is easy to understand that, in order to facilitate encapsulation, the traction mechanism 200 pulls the adhesive tape 1, and when the adhesive tape 1 is pulled through the cell support mechanism 300, the adhesive tape 1 is not far away from the cell 10 supported by the cell support mechanism 300, that is, the cell support mechanism 300 is not far away from the traction mechanism 200, the unwinding mechanism 100 and the turnover mechanism 400; in this case, the charging of the battery cell 10 to be encapsulated and the discharging of the battery cell after encapsulation are both inconvenient and easily interfered by other mechanisms. For this reason, set up translation mechanism 380, when unloading on electric core 10, drive electric core supporting mechanism 300 and keep away from the rubber coating station for unwinding mechanism 100, drive mechanism 200 and tilting mechanism 400 are kept away from to electric core supporting mechanism 300, and then are convenient for taking out and putting into of electric core 10.

Wherein, translation mechanism 380 can adopt driving members such as electric jar, sharp module, and translation mechanism 380 is located to electric core supporting mechanism 300's output, and translation mechanism 380 can drive electric core supporting mechanism 300 horizontal motion to make electric core supporting mechanism 300 be close to or keep away from the rubber coating station.

It should be noted that the "encapsulation station" is a position where the battery cell 10 is encapsulated. In the above, the cell support mechanism 300 is located at the encapsulation station; at this time, the cell support mechanism 300 is located downstream of the unwinding mechanism 100, and the turnover mechanism 400 is disposed outside the cell support mechanism 300 and directly opposite to the first end and/or the second end of the cell 10; the traction mechanism 200 pulls the adhesive tape 1 to the encapsulation station, and the adhesive surface of the adhesive tape 1 is opposite to the battery cell 10.

The encapsulating device further comprises a cutting mechanism 500 which is arranged at the downstream of the unreeling mechanism 100 and at the upstream of the cell supporting mechanism 300; the cutting mechanism 500 includes: a cutting member 510 and a cutting drive member 520, the cutting drive member 520 being connected to the cutting member 510 and being capable of driving the cutting member 510 to move toward the adhesive tape 1 so that the cutting member 510 cuts the adhesive tape 1.

Referring to fig. 9, in a specific embodiment, the traction mechanism 200 pulls the adhesive tape 1 to a position where the battery cell 10 is to be pasted with adhesive, and the leveling mechanism 700 gradually levels the adhesive tape 1 on the upper surface 11; after the encapsulation of the upper surface 11 is finished, the turnover mechanism 400 extracts the battery cell 10 and drives the battery cell 10 to rotate until the side surface 12 of the battery cell gradually approaches the adhesive tape 1; after the encapsulation of the side surface 12 is finished, the turnover mechanism 400 continues to rotate the battery cell 10 until the lower surface 13 of the battery cell gradually approaches the adhesive tape 1; the turnover mechanism 400 releases the battery cell 10, so that the battery cell 10 returns to the battery cell support mechanism 300, so that the flattening mechanism 700 gradually flattens the adhesive tape 1 on the lower surface 13. Before the adhesive tape 1 completely covers the lower surface 13, the cutting driving member 520 drives the cutting member 510 to cut the adhesive tape 1, so that the leveling mechanism 700 levels the cut tail of the adhesive tape 1 on the lower surface 13, thereby completing three-sided encapsulation of the battery cell 10.

The cutting member 510 may be a serrated knife longer than the width of the adhesive tape 1, and when the cutting member is not used, the serrated knife is disposed opposite to the non-adhesive surface of the adhesive tape 1, and when the cutting member is used for cutting, the cutting driving member 520 drives the serrated knife to move towards the adhesive tape 1, so as to directly cut the adhesive tape 1. Or, the cutting member 510 may be a common cutter, when not cutting, the cutter is disposed on one side of the adhesive tape 1 in the width direction, the blade is aligned with the adhesive tape 1, and when cutting, the cutting driving member 520 drives the cutter to move from one side of the adhesive tape 1 to the other side along the width direction of the adhesive tape 1, so as to cut the adhesive tape 1.

Further, the encapsulation device further comprises an auxiliary cutting mechanism 600; supplementary mechanism 600 that cuts includes: the first auxiliary assembly 610 is arranged at the downstream of the unwinding mechanism 100 and at the upstream of the cutting mechanism 500 and can fix the corresponding adhesive tape 1; and/or the second auxiliary assembly 620 is disposed downstream of the cutting mechanism 500 and upstream of the cell support mechanism 300, and can fix the corresponding adhesive tape 1.

The cutting driving member 520 may be a driving member such as an air cylinder or an electric cylinder.

As will be readily understood, when cutting the adhesive tape 1 by the cutting mechanism 500, it is necessary to ensure that the adhesive tape 1 is tensioned so that the cutting member 510 can stably cut the adhesive tape 1 by the driving of the cutting driving member 520. Thus, providing the auxiliary cutting mechanism 600 near (upstream and/or downstream of) the cutting mechanism 500 enables fixing the adhesive tape 1 before cutting, so that the adhesive tape 1 is kept in a stable state for easy cutting.

Referring to fig. 9 and 10, in particular, each of the first auxiliary component 610 and the second auxiliary component 620 may include: the adhesive tape 1 penetrates through the space between the first rubber pressing plate 611 and the second rubber pressing plate 612; and a glue pressing driving part 613, capable of driving the first glue pressing plate 611 and the second glue pressing plate 612 to move relatively, so as to press the adhesive tape 1 therebetween; after the adhesive tape 1 passes through the first auxiliary component 610 and the second auxiliary component 620, the adhesive tape is extracted by the traction mechanism 200 and pulled through the electric core supporting mechanism 300; before the cutting mechanism 500 cuts the adhesive tape 1, the adhesive pressing driving piece 613 can drive the first adhesive pressing plate 810 and the second adhesive pressing plate 820 to move in opposite directions and compress the adhesive tape 1, so as to tension the adhesive tape 1, thereby facilitating cutting.

By providing the first auxiliary member 610 and the second auxiliary member 620, the adhesive tape 1 near the cutting mechanism 500 can be better defined, facilitating cutting.
