[0026] The following will be combined with the drawings in the embodiments of the present application to clearly and completely describe the technical solutions in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of this application.

[0027] See also Figure 1-Figure 10 The present application discloses a rubber coating device for coating a battery cell 10, which includes: a reeling mechanism 100, for releasing the adhesive tape 1; a traction mechanism 200, arranged downstream of the reeling mechanism 100, capable of pulling out the adhesive tape 1 in the reeling mechanism 100; a battery cell supporting mechanism 300, arranged downstream of the reeling mechanism 100 and upstream of the traction mechanism 200, for supporting the battery cell 10; a flipping mechanism 400, arranged outside the battery cell supporting mechanism 300, capable of extracting the battery cell supporting mechanism The battery cell 10 on the structure 300 is pulled out by the pulling mechanism 200, and the battery cell 10 is turned over; wherein, the traction mechanism 200 pulls out the adhesive tape 1 from the unwinding mechanism 100, and pulls the adhesive tape 1 through the battery cell supporting mechanism 300, so that the adhesive tape 1 is attached to the surface of the battery cell 10 on the battery cell supporting mechanism 300; after the adhesive tape 1 covers the upper surface 11 of the battery cell 10, the turning 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...

[0028] Specific reference Figure 1 and Figure 2, the material roll formed by the adhesive tape 1 is wound on the unwinding shaft of the unwinding mechanism 100; when the traction mechanism 200 pulls the adhesive tape 1, it pulls the free end of the adhesive tape 1 and pulls the adhesive tape 1 toward the battery cell support mechanism 300; at the same time, the unwinding shaft rotates to release the adhesive tape 1, so that the traction mechanism 200 can pull the adhesive tape 1 through the battery cell support mechanism 300. The battery cell 10 to be encapsulated is placed on the battery cell support mechanism 300, and the upper surface 11 of the battery cell 10 faces the adhesive surface of the adhesive tape 1. The traction mechanism 200 pulls out the adhesive tape 1 and makes the adhesive surface of the adhesive tape 1 stick to the upper surface 11 of the battery cell 10. Subsequently, the flipping 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 can cover the side surface 12 of the battery cell 10. Afterwards, the flipping mechanism 400 can continue to drive the battery cell 10 to rotate, so that the battery cell 10 is adjacent to the side surface 12 and the lower surface 13 opposite to the upper surface 11 is close to the adhesive surface of the tape 1, so that the tape 1 can cover the lower surface 13 of the battery cell 10...thereby, multiple layers of adhesive coating of the battery cell 10 are achieved.

[0029] In order to facilitate the traction mechanism 200 to pull the tape 1 through the battery cell support mechanism 300, during the process of pulling the tape 1, the traction mechanism 200 will be above the battery cell support mechanism 300 to avoid the battery cell support mechanism 300, and finally pull the tape 1 to the position corresponding to the battery cell 10 to be encapsulated. After the tape 1 is in place, the traction mechanism 200 can be lowered to attach the tape 1 to the battery cell 10; or, after the tape 1 is in place, the battery cell support mechanism 300 can be raised to attach the battery cell 10 to the tape 1.

[0030] In order to ensure that the tape 1 is stably adhered to the surface of the battery cell 10, the adhesive coating device provided in the present application also includes a smoothing mechanism 700; the smoothing mechanism 700 includes: a smoothing piece 710, which is arranged above the battery cell support mechanism 300; a smoothing drive assembly 720, which is connected to the smoothing piece 710; wherein the smoothing drive assembly 720 can drive the smoothing piece 710 to be close to the battery cell support mechanism 300 to smooth the tape 1 on the battery cell 10.

[0031] Specifically, in the initial state, the smoothing member 710 is facing the battery cell 10 to be coated supported by the battery cell support mechanism 300 and suspended above the battery cell 10. After the traction mechanism 200 pulls the adhesive tape 1 to the initial position of the battery cell 10 to be coated, the smoothing drive assembly 720 drives the smoothing member 710 to descend and abut against the battery cell 10, thereby pressing the adhesive tape 1 against the surface of the battery cell 10. Before the flipping mechanism 400 is activated, the smoothing drive assembly 720 drives the smoothing member 710 to rise and move away from the battery cell 10, so that the flipping mechanism 400 can drive the battery cell 10 to flip over.

[0032] In one embodiment, the smoothing member 710 may be a pressing block larger than the surface of the battery cell 10 ; thus, when the smoothing driving assembly 720 drives the smoothing member 710 against the battery cell 10 , the smoothing member 710 may directly press the tape 1 flat on the entire surface of the battery cell 10 .

[0033] In another embodiment, referring to Figure 3 , the smoothing member 710 can be a pressure roller; at this time, the smoothing drive assembly 720 can drive the smoothing member 710 to press against the battery cell 10 to press the tape 1 onto the surface of the battery cell 10, and can also drive the smoothing member 710 to move along the surface of the battery cell 10 to smooth the tape 1 on the surface of the battery cell 10.

[0034] Specifically, the smoothing drive component 720 includes: a first smoothing drive component 721, which is connected to the smoothing member 710 and can drive the smoothing member 710 to move closer to or away from the battery cell support mechanism 300; a second smoothing drive component 722, which is connected to the smoothing member 710 and can drive the smoothing member 710 to move along the surface of the battery cell 10; wherein the smoothing member 710 can be arranged at the output end of the first smoothing drive component 721, and the main body of the first smoothing drive component 721 is arranged at the output end of the second smoothing drive component 722; or, the smoothing member 710 can be arranged at the output end of the second smoothing drive component 722, and the main body of the second smoothing drive component 722 is arranged at the output end of the first smoothing drive component 721.

[0035] In this embodiment, the first smoothing drive component 721 can drive the smoothing member 710 to move in the vertical direction, and the second smoothing drive component 722 can drive the smoothing member 710 to move in the horizontal direction. In this way, after the traction mechanism 200 pulls the tape 1 into place, the first smoothing drive component 721 first drives the smoothing member 710 to press down, pressing the tape 1 against the upper surface 11 of the battery cell. At this time, the smoothing member 710 is against the initial position of the battery cell 10 to be encapsulated. Subsequently, the second smoothing drive component 722 drives the smoothing member 710 to move along the upper surface 11 toward the side surface 12, so as to gradually smooth the tape 1 on the surface of the battery cell 10.

[0036] By setting the smoothing member 710 as a pressure roller, when the smoothing member 710 is driven to move along the surface of the battery cell 10, the pressure roller can rely on the self-rotation of the roller to smooth and press the tape 1 while moving smoothly. Furthermore, by setting the smoothing member 710 to move along the surface of the battery cell 10, the tape 1 and the battery cell 10 can be better fitted.

[0037] The smoothing drive assembly 720, or the first smoothing drive assembly 721 and the second smoothing drive assembly 722 may adopt drive components such as electric cylinders and linear modules.

[0038] The traction mechanism 200 includes: a first traction component 210 and a second traction component 220, which are arranged at intervals along the width direction of the tape 1 and can respectively extract one end of the tape 1; a traction drive component 230, which connects the first traction component 210 and the second traction component 220, and can drive the first traction component 210 and the second traction component 220 to approach the unwinding mechanism 100 to extract the tape 1, and pull the tape 1 toward the battery cell support mechanism 300.

[0039] Among them, the first traction component 210 and the second traction component 220 can use extraction components such as clamps and suction cups to extract the free end of the tape 1, and then be driven by the traction drive component 230 to make the first traction component 210 and the second traction component 220 move forward with the tape 1.

[0040] In one embodiment, the traction drive assembly 230 may include only the first traction drive assembly 231. The first traction assembly 210 and the second traction assembly 220 are both disposed at the output end of the first traction drive assembly 231 and can move between the unwinding mechanism 100 and the battery cell support mechanism 300 under the drive of the first traction drive assembly 231. The first traction drive assembly 231 may use a driving member such as an electric cylinder or a linear module.

[0041] In this embodiment, the first traction drive component 231 is used to drive the first traction component 210 and the second traction component 220 to pull out the tape 1 from the unwinding mechanism 100, and pull the tape 1 to the initial position facing the battery cell 10 to be wrapped with adhesive; at this time, the tape 1 is above the battery cell 10; the smoothing drive component 720 drives the smoothing member 710 to press against the battery cell 10, pressing the tape 1 onto the battery cell 10.

[0042] In another embodiment, referring to Figure 4 , the traction drive assembly 230 may only include a first traction drive assembly 231 and a second traction drive assembly 232; the first traction drive assembly 231 connects and drives the first traction assembly 210 and the second traction drive assembly 220 to move in the horizontal direction between the unwinding mechanism 100 and the battery cell support mechanism 300, so as to pull the tape 1 to the position to be coated; the second traction drive assembly 232 connects and drives the first traction assembly 210 and the second traction assembly 220 to move in the vertical direction, so as to stick the tape 1 to the surface of the battery cell 10. Among them, the first traction assembly 210 and the second traction assembly 220 may be arranged at the output end of the first traction drive assembly 231, and the main body of the first traction drive assembly 231 is arranged at the output end of the second traction drive assembly 232; or the first traction assembly 210 and the second traction assembly 220 may be arranged at the output end of the second traction drive assembly 232, and the main body of the second traction drive assembly 232 is arranged at the output end of the first traction drive assembly 231.

[0043] In this embodiment, the first traction drive component 231 is used to drive the first traction component 210 and the second traction component 220 to pull out the tape 1 from the unwinding mechanism 100, and pull the tape 1 to the initial position facing the battery cell 10 to be wrapped with glue; at this time, the tape 1 is above the battery cell 10; then, the second traction drive component 232 drives the first traction component 210 and the second traction component 220 to pull the tape 1 toward the upper surface 11 of the battery cell, so that the tape 1 sticks to the battery cell 10; then, the smoothing drive component 720 drives the smoothing member 710 to press against the battery cell 10 to better smooth the tape 1 along the surface of the battery cell 10.

[0044] By setting up the second traction drive component 232, the tape 1 can be pre-attached to the battery cell 10 after the tape 1 is pulled out; in this way, it can be avoided that the smoothing member 710 presses down the suspended tape 1, causing the tape 1 to be pulled out of the first traction component 210 and the second traction component 220, thereby causing the free end of the tape 1 to be deformed.

[0045] The first traction drive assembly 231 and the second traction drive assembly 232 may adopt drive components such as electric cylinders and linear modules.

[0046] It is easy to understand that the tape 1 has a certain width. To prevent the tape 1 from being folded or twisted, the tape 1 can be stretched along its width direction before being attached to the battery cell 10 to ensure that the tape 1 is fully unfolded, thereby improving the effect of the adhesive application. To this end, the traction mechanism 200 also includes a pre-stretching component 240, which connects the first traction component 210 and the second traction component 220 and can drive the first traction component 210 and the second traction component 220 to move closer to each other or away from each other.

[0047] Specifically, the pre-stretching component 240 includes: a pre-stretching guide 241, which is extended along the width direction of the tape 1, and the first traction component 210 and / or the second traction component 220 are slidably connected to the pre-stretching guide 241; a pre-stretching driving component 242, which can drive the first traction component 210 and the second traction component 220 to move relative to each other; wherein, after the first traction component 210 and the second traction component 220 clamp the tape 1, the pre-stretching driving component 242 can drive the first traction component 210 and / or the second traction component 220 away from each other along the pre-stretching guide 241, thereby stretching the tape 1.

[0048] Specific reference Figure 4At least one of the first traction assembly 210 and the second traction assembly 220 is slidably connected to the pre-stretching guide 241, and can be driven away from the other traction assembly by the pre-stretching driving member 242 to stretch the tape 1. In order to reduce the movement stroke of the traction assembly and speed up the stretching action, the first traction assembly 210 and the second traction assembly 220 can be slidably connected to the pre-stretching guide 241; and two pre-stretching driving members 242 can be provided, which are respectively connected to the first traction assembly 210 and the second traction assembly 220 to drive the relative movement of the two; in this way, after the first traction assembly 210 and the second traction assembly 220 extract the tape 1 and before the tape 1 is attached to the battery cell 10, the two pre-stretching driving members 242 are actuated to drive their respective corresponding jaws 110 away from the other jaw 110, thereby stretching the tape 1 so that the tape 1 is fully unfolded. Alternatively, the pre-stretching driving member 242 can adopt an air claw, and the first traction component 210 and the second traction component 220 are respectively arranged on an output end of the air claw; in this way, after the first traction component 210 and the second traction component 220 extract the tape 1 and before the tape 1 is attached to the battery cell 10, the pre-stretching driving member 242 can simultaneously drive the first traction component 210 and the second traction component 220 to move in opposite directions, thereby stretching the tape 1.

[0049] The pre-stretching guide member 241 may be a guide member such as a guide rail or a guide rod, and the pre-stretching drive member 242 may be a linear drive member such as a cylinder or an electric cylinder.

[0050] During the encapsulation process, when the flipping mechanism 400 is used to flip the battery cell 10, the flipping mechanism 400 needs to clamp the first end and / or the second end of the battery cell 10. The so-called first end and second end are the two ends of the battery cell 10 corresponding to the width direction of the tape 1; for example, Figure 1 In the figure, the side of the battery cell 10 that is vertically upward is the upper surface 11; the side that is arranged opposite to the upper surface 11 and vertically downward is the lower surface 13; the side that is adjacent to the upper surface 11 and the lower surface 13 and horizontally facing left is the side surface 12; and the first end and the second end are the front and rear ends that are perpendicular to the paper and adjacent to the upper surface 11, the side surface 12 and the lower surface 13. As the tape 1 gradually adheres to the upper surface 11 from right to left, and then adheres to the side surface 12 and the lower surface 13; the upper surface 11 is coated with glue, the flipping mechanism 400 clamps the first end and / or the second end of the battery cell 10, and flips the battery cell 10 so that the side surface 12 faces the tape 1. At this time, the flipping mechanism 400 will not affect the glue coating of the side surface 12.

[0051] Specifically, the flip mechanism 400 includes: a flip extraction member 410 capable of extracting the battery cell 10 ; and a flip driving member 420 connected to the flip extraction member 410 and capable of driving the flip extraction member 410 to rotate.

[0052] The flipping extraction member 410 may be an extraction member such as a suction cup or a clamp; and the flipping driving member 420 may be a rotation driving member such as a motor.

[0053] After the upper surface 11 is coated with glue, the flip extraction member 410 extracts the battery cell 10 on the battery cell support mechanism 300, and the flip driving member 420 further drives the flip extraction member 410 to drive the battery cell 10 to rotate.

[0054] In one embodiment, the first end and / or the second end of the battery cell 10 partially protrudes from the battery cell support mechanism 300. At this time, the flip extraction member 410 does not need to avoid the position and can directly extract the protruding part of the battery cell 10. However, when encapsulating, the battery cell 10 should be supported on the battery cell support mechanism 300 as a whole, so that when the smoothing member 710 smoothes the tape 1, the position of the battery cell 10 is stable and the tape 1 can be firmly pressed and smoothed on the battery cell 10. For this reason, refer to Figure 5 The flip mechanism 400 also includes a flip avoidance driving assembly 430 , which is connected to the flip extraction member 410 and can drive the flip extraction member 410 to move closer to or away from the battery cell supporting mechanism 300 .

[0055] Among them, the flip extraction member 410 is arranged at the output end of the flip driving member 420, and the main body of the flip driving member 420 is arranged at the output end of the flip avoidance driving component 430; or, the flip extraction member 410 is arranged at the output end of the flip avoidance driving component 430, and the main body of the flip avoidance driving component 430 is arranged at the output end of the flip driving member 420.

[0056] At this time, the flip extractor 410 can be arranged at the output end of the flip drive 420, and the main body of the flip drive 420 is arranged at the output end of the flip avoidance drive assembly 430; or, the flip extractor 410 can be arranged at the output end of the flip avoidance drive assembly 430, and the main body of the flip avoidance drive assembly 430 is arranged at the output end of the flip drive 420. The flip avoidance drive assembly 430 can adopt a driving component of a cylinder, an electric cylinder, or a linear module.

[0057] Specifically, the battery cell 10 is supported as a whole on the battery cell support mechanism 300. When not turned over, the flip extraction member 410 is away from the battery cell support mechanism 300 to facilitate loading and unloading of the battery cell 10 and the wrapping of the tape 1. After the upper surface 11 is coated with glue, the flip avoidance drive assembly 430 drives the flip extraction member 410 to approach the battery cell support mechanism 300 to facilitate the flip extraction member 410 to extract the battery cell 10; after the flip extraction member 410 extracts the battery cell 10, the flip drive member 420 further drives the flip extraction member 410 to rotate the battery cell 10. After the flip is completed, the flip extraction member 410 releases the battery cell 10, and the flip avoidance drive assembly 430 drives the flip extraction member 410 away from the battery cell support mechanism 300 to facilitate the continued coating and unloading of the battery cell 10.

[0058] Furthermore, in order to stably flip the battery cell 10, the encapsulation device provided in the present application includes two sets of flipping mechanisms 400, which are relatively arranged on both sides of the battery cell support mechanism 300 along the width direction of the tape 1, and can extract the two ends of the battery cell 10 to facilitate the stable rotation of the battery cell 10.

[0059] For example, the flip extraction member 410 may be a clamp; when extracting the battery cell 10, the two groups of clamps can clamp the first end and the second end of the battery cell 10 respectively, thereby stably rotating the battery cell 10. Alternatively, the two groups of flip extraction members 410 may also cooperate to form a clamp, for example, the flip extraction member 410 may be a clamp, and the two clamps are arranged on both sides of the battery cell support mechanism 300 relative to the first end and the second end of the battery cell 10; when the battery cell 10 needs to be rotated, the flip avoidance drive assembly 430 drives the two clamps to move relative to each other, so that one of the clamps is against the first end of the battery cell 10, and the other clamp is against the second end of the battery cell 10, thereby cooperating to clamp the battery cell 10, so that the flip drive member 420 further drives the flip extraction member 410 and drives the battery cell 10 to rotate.

[0060] Furthermore, the encapsulation device provided in the present application also includes a lifting mechanism 390; the lifting mechanism 390 is connected to the battery cell supporting mechanism 300, and after the flipping mechanism 400 extracts the battery cell 10, the lifting mechanism 390 can drive the battery cell supporting mechanism 300 to descend, so that the battery cell 10 can be separated from the battery cell supporting mechanism 300 and flipped; or, the lifting mechanism 390 is connected to the flipping mechanism 400, and after the flipping mechanism 400 extracts the battery cell 10, the lifting mechanism 390 can drive the flipping mechanism 400 to rise, so that the battery cell 10 can be separated from the battery cell supporting mechanism 300 and flipped.

[0061] It is easy to understand that the battery cell 10 is placed on the battery cell support mechanism 300. When flipping, it is necessary to leave space for the battery cell 10 to move to avoid interference between the battery cell 10 and the battery cell support mechanism 300. At this time, a lifting mechanism 390 is set to drive the flipping mechanism 400 to rise with the battery cell 10, or drive the battery cell support mechanism 300 to descend, or, while driving the flipping mechanism 400 to rise with the battery cell 10, it also drives the battery cell support mechanism 300 to descend, so that the battery cell 10 is separated from the battery cell support mechanism 300, and there is space between the battery cell 10 and the battery cell support mechanism 300 for the battery cell 10 to flip.

[0062] At this time, the lifting mechanism 390 can use driving components such as electric cylinders and linear modules, which can drive the flipping mechanism 400 or the battery cell supporting mechanism 300 connected thereto to move in the vertical direction.

[0063] In addition, when the battery cell 10 is supported on the battery cell support mechanism 300 as a whole, in order to facilitate the flipping of the extraction member 410 to extract the battery cell 10 from the battery cell support mechanism 300, refer to Figures 6 to 8 The cell support mechanism 300 includes: a support platform 310 for supporting the middle part of the cell 10; a first platform 320, which is arranged on one side of the support platform 310 and can support the first part of the cell 10; a second platform 330, which is arranged on the other side of the support platform 310 and can support the second part of the cell 10; a platform driving component 340, which connects the first platform 320 and the second platform 330 and can drive the first platform 320 and the second platform 330 to move in a vertical direction; wherein the platform driving component 340 can drive the first platform 320 and the second platform 330 to rise until the surfaces of the first platform 320 and the second platform 330 for supporting the cell 10 are coplanar with the surface of the support platform 310 for supporting the cell 10, so that the first platform 320, the second platform 330 and the support platform 310 cooperate to support the entire cell 10; the platform driving component 340 can also drive the first platform 320 and the second platform 330 to descend, so that the first part and the second part of the cell 10 lose support.

[0064] Specifically, for the battery cell support mechanism 300, its support platform 310 is relatively fixed and can always support the battery cell 10; at the same time, since the support platform 310 supports the middle part of the battery cell 10, after the two ends of the battery cell 10 are separated from the support of the first platform 320 and the second platform 330, they can still be supported by the support platform 310 and will not fall.

[0065] The first part and the second part of the battery cell 10 correspond to the first end and the second end of the battery cell 10 and are located at both ends of the battery cell 10 .

[0066] In a specific embodiment, the flipping extractor 410 is a clamp. After the upper surface 11 of the battery cell is coated with glue, the platform driving assembly 340 drives the first platform 320 and the second platform 330 to descend, so that the first part and the second part 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 support mechanism 300. At this time, one clamp of the clamp faces the upper surface 11 of the battery cell 10, and the other clamp is inserted between the battery cell 10 and the battery cell support mechanism 300 and faces the lower surface 13 of the battery cell 10. The two clamps move toward each other and then clamp the battery cell 10. After the battery cell 10 is turned over, the flipping extractor 410 releases the battery cell 10, so that the battery cell 10 returns to the support platform 310. At this time, the platform driving assembly 340 can drive the first platform 320 and the second platform 330 to rise to support the entire battery cell 10, so as to facilitate the new side to be coated with glue.

[0067] It is easy to imagine that the platform driving assembly 340 can 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 to support the battery cell 10 or release the support for the end of the battery cell 10. Alternatively, the platform driving assembly 340 can use two sets of driving members, 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 needs of the flip extraction member 410.

[0068] The platform driving assembly 340 may adopt driving components such as a pneumatic cylinder and an electric cylinder.

[0069] In order to limit the movement direction of the first platform 320 and the second platform 330 and ensure that the platform driving assembly 340 can 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 guide member may be further provided, such as a guide rod or a guide rail provided in a vertical direction; the first platform 320 and the second platform 330 are slidably provided on the guide member.

[0070] In another embodiment, the support platform 310 has a raised portion on one side close to the first platform 320, and the first platform 320 has a concave portion at a position corresponding to the raised portion, and the raised portion extends into the concave portion; when the platform driving assembly 340 drives the first platform 320 to move in a vertical direction, the concave portion moves along the raised portion, and the movement direction of the first platform 320 is limited by the cooperation of the two.

[0071] Specific reference Figure 6 and Figure 8 The support platform 310 and the first platform 320 have a certain thickness. When the protrusion is inserted into the concave part, the support platform 310 and the first platform 320 have multiple surfaces that abut against each other. In this way, when the platform driving assembly 340 drives the first platform 320 to move in the vertical direction, the protrusion and the concave part guide each other, so that the first platform 320 can only move in the extension direction of the thickness of the protrusion, that is, in the vertical direction, thereby ensuring the stability of the movement of the first platform 320.

[0072] Similarly, the support platform 310 has a raised portion on one side close to the second platform 330, and the second platform 330 has a concave portion at a position corresponding to the raised portion, and the raised portion extends into the concave portion; when the platform driving assembly 340 drives the second platform 330 to move in a vertical direction, the concave portion moves along the raised portion, and the movement direction of the second platform 330 is limited by the cooperation of the two.

[0073] The guiding cooperation manner of the supporting platform 310 and the second platform 330 is similar to the guiding cooperation manner of the supporting platform 310 and the first platform 320 , and will not be described in detail here.

[0074] Furthermore, the battery cell support mechanism 300 also includes a base plate 370: the base plate 370 is fixedly arranged relative to the support platform 310; the base plate 370 has a protruding block portion; the first platform 320 and the second platform 330 have a recessed slot portion facing the base plate 370; the platform driving component 340 drives the first platform 320 and the second platform 330 to descend, so that the slot portion gradually approaches the block portion, and the block portion sinks into the slot portion, which can further limit the position of the first platform 320 and the second platform 330.

[0075] By setting the bottom plate 370, the movement paths of the first platform 320 and the second platform 330 can be limited. The platform driving assembly 340 drives the first platform 320 and the second platform 330 to descend. Finally, the first platform 320 and the second platform 330 will abut against the bottom plate 370, and the bottom 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 plug-in matching block part and the card slot part, ensuring the stability of the first platform 320 and the second platform 330 in the vertical direction, and ensuring the stable operation of the equipment.

[0076] Furthermore, the battery cell supporting mechanism 300 further includes a fixing assembly 360 , which is disposed outside the supporting platform 310 and can limit the position of the battery cell 10 .

[0077] It is easy to understand that after the battery cells 10 are loaded, it is necessary to ensure that the positions of the battery cells 10 placed in the battery cell support mechanism 300 remain constant, so as to ensure the accuracy of the rubber encapsulation. At this time, the fixing component 360 can adopt a fixing block, and the fixing block is surrounded by a semi-enclosed frame that can only accommodate the battery cell 10, thereby limiting the position of the battery cell 10. Alternatively, the fixing component 360 can also adopt a suction cup that can absorb the battery cell 10 and thereby limit the position of the battery cell 10. Alternatively, the fixing component 360 can adopt a clamp, and after the battery cell 10 is placed in the battery cell support mechanism 300, the clamp clamps the battery cell 10 and thereby limits the position of the battery cell 10.

[0078] Alternatively, the fixed component 360 includes: a fixed part 361, which is fixedly set on one side of the support platform 310; a movable part 362, which is set on the other side of the support platform 310 relative to the fixed part 361; and a fixed driving part 363, which is connected to the movable part 362 and can drive the movable part 362 to approach or move away from the fixed part 361.

[0079] 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 presses the battery cell 10 between the fixed member 361 and the movable member 362. At this time, the fixed member 361 is equivalent to the reference position, and when one side of the battery cell 10 abuts against the fixed member 361, it can ensure that the battery cell 10 is in a fixed position in the battery cell support mechanism 300.

[0080] Furthermore, a flexible member 364 is provided on one side of the fixing member 361 and / or the movable member 362 that abuts against the battery cell 10 .

[0081] Specifically, the flexible member 364 can be made of flexible materials such as polyurethane and rubber. By pressing the battery cell 10 with the flexible member 364, it is possible to avoid the battery cell 10 being damaged when the fixed member 361 or the movable member 362 made of rigid material continuously presses against the battery cell 10. At the same time, since the flexible member 364 has a certain deformation amount, when the fixed driving member 363 continuously drives the movable member 362 to press against the battery cell 10 to compress the battery cell 10, the flexible member 364 is compressed, thereby compensating for the excess stroke output by the fixed driving member 363; at the same time, the flexible member 364 has an elastic restoring force, which can act in the opposite direction on the battery cell 10 to ensure that the fixed member 361 and the movable member 362 compress the battery cell 10.

[0082] Furthermore, the encapsulation device also includes a translation mechanism 380 ; the translation mechanism 380 is connected to the battery cell support mechanism 300 and can drive the battery cell support mechanism 300 to approach or move away from the flip mechanism 400 to facilitate loading and unloading of the battery cells 10 on the battery cell support mechanism 300 .

[0083] It is easy to understand that, in order to facilitate the rubber coating, the traction mechanism 200 pulls the tape 1. When the tape 1 is pulled through the battery cell support mechanism 300, the tape 1 will not be far away from the battery cell 10 supported on the battery cell support mechanism 300, that is, the battery cell support mechanism 300 will not be too far away from the traction mechanism 200, the unwinding mechanism 100 and the flipping mechanism 400; in this case, the loading of the battery cell 10 to be coated with rubber and the unloading of the battery cell after the rubber coating are inconvenient and are easily interfered by other mechanisms. For this reason, a translation mechanism 380 is set to drive the battery cell support mechanism 300 away from the rubber coating station when loading and unloading the battery cell 10, so that the battery cell support mechanism 300 is away from the unwinding mechanism 100, the traction mechanism 200 and the flipping mechanism 400, thereby facilitating the removal and placement of the battery cell 10.

[0084] Among them, the translation mechanism 380 can adopt driving components such as electric cylinders and linear modules. The battery cell support mechanism 300 is arranged at the output end of the translation mechanism 380. The translation mechanism 380 can drive the battery cell support mechanism 300 to move horizontally so that the battery cell support mechanism 300 is close to or away from the encapsulation station.

[0085] It should be noted that the "glue encapsulation station" is the position where the battery cell 10 is glued. In the above text, the position where the battery cell support mechanism 300 is located is all in the glue encapsulation station; at this time, the battery cell support mechanism 300 is downstream of the unwinding mechanism 100, and the flip mechanism 400 is arranged outside the battery cell support mechanism 300, facing the first end and / or the second end of the battery cell 10; the traction mechanism 200 pulls the tape 1 to the glue encapsulation station, and the glue surface of the tape 1 faces the battery cell 10.

[0086] The rubber coating device also includes a cutting mechanism 500, which is arranged downstream of the unwinding mechanism 100 and upstream of the battery cell supporting mechanism 300; the cutting mechanism 500 includes: a cutting piece 510 and a cutting drive piece 520, the cutting drive piece 520 is connected to the cutting piece 510, and can drive the cutting piece 510 to move toward the tape 1, so that the cutting piece 510 cuts the tape 1.

[0087] Reference Fig. 9 In a specific embodiment, the traction mechanism 200 pulls the tape 1 to the position where the battery cell 10 is to be glued, and the smoothing mechanism 700 gradually smoothes the tape 1 on the upper surface 11; after the glue coating of the upper surface 11 is completed, the flipping 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 tape 1; after the glue coating of the side surface 12 is completed, the flipping mechanism 400 continues to rotate the battery cell 10 until the lower surface 13 of the battery cell gradually approaches the tape 1; the flipping mechanism 400 releases the battery cell 10, so that the battery cell 10 returns to the battery cell support mechanism 300, so that the smoothing mechanism 700 gradually smoothes the tape 1 on the lower surface 13. Before the tape 1 completely covers the lower surface 13, the cutting drive member 520 drives the cutting member 510 to cut the tape 1, so that the smoothing mechanism 700 smoothes the cut tail of the tape 1 on the lower surface 13, thereby completing the glue coating of the battery cell 10 on three sides.

[0088] The cutting member 510 may be a serrated knife longer than the width of the tape 1. When not cutting, the serrated knife is arranged relative to the non-adhesive surface of the tape 1. When cutting, the cutting drive 520 drives the serrated knife to move toward the tape 1 to directly cut the tape 1. Alternatively, the cutting member 510 may be an ordinary cutter. When not cutting, the cutter is arranged at one side in the width direction of the tape 1, with the blade facing the tape 1. When cutting, the cutting drive 520 drives the cutter to move along the width direction of the tape 1 from one side of the tape 1 to the other side, thereby cutting the tape 1.

[0089] Furthermore, the rubber coating device also includes an auxiliary cutting mechanism 600; the auxiliary cutting mechanism 600 includes: a first auxiliary component 610, which is arranged downstream of the unwinding mechanism 100 and upstream of the cutting mechanism 500, and can fix its corresponding tape 1; and / or, a second auxiliary component 620, which is arranged downstream of the cutting mechanism 500 and upstream of the battery cell supporting mechanism 300, and can fix its corresponding tape 1.

[0090] The cutting drive member 520 may be a drive member such as a cylinder or an electric cylinder.

[0091] It is easy to understand that when the cutting mechanism 500 cuts the tape 1, it is necessary to ensure that the tape 1 is tensioned so that the cutting member 510 can stably cut the tape 1 under the drive of the cutting drive member 520. Therefore, an auxiliary cutting mechanism 600 is provided near the cutting mechanism 500 (upstream and / or downstream) to fix the tape 1 before cutting, so that the tape 1 remains in a stable state and is convenient for cutting.

[0092] Reference Fig. 9 and Fig.10 Specifically, the first auxiliary component 610 and the second auxiliary component 620 may include: a first glue pressing plate 611 and a second glue pressing plate 612, between which the tape 1 passes; and a glue pressing driving member 613, which can drive the first glue pressing plate 611 and the second glue pressing plate 612 to move relative to each other to compress the tape 1 therebetween; wherein, after the tape 1 passes through the first auxiliary component 610 and the second auxiliary component 620, it is extracted by the traction mechanism 200 and pulled through the battery cell support mechanism 300; before the cutting mechanism 500 cuts off the tape 1, the glue pressing driving member 613 can drive the first glue pressing plate 810 and the second glue pressing plate 820 to move toward each other, compress the tape 1, and then tension the tape 1 to facilitate cutting.

[0093] By providing the first auxiliary component 610 and the second auxiliary component 620, the adhesive tape 1 near the cutting mechanism 500 can be better limited to facilitate cutting.

[0094] In addition, the terms "include" and "have" and any variations thereof are intended to cover non-exclusive inclusions. For example, a process, method, system, product or apparatus comprising a series of steps or components is not limited to the listed steps or components, but may optionally include steps or components not listed, or may optionally include other steps or components inherent to these processes, methods, products or apparatuses.
