Description

Technical Field

[0001] The utility model relates to the technical field of batteries, in particular to a battery core coating device. Background Art

[0002] like Figure 4 As shown, it is a single cell c, specifically a square shell cell. Figure 3a is the insulating film a of the single cell c, Figure 3b The bottom support plate b of the single cell c. Specifically, the insulating film a and the bottom support plate b together constitute a coating film body, which is used to coat the single cell c to insulate it. The insulating film a includes a large surface a1, a side surface a2, and a bottom surface a3, wherein the large surface a1 corresponds to the large surface c1 of the cell, the side surface a2 corresponds to the side surface c2 of the cell, and the bottom surface a3 corresponds to the bottom surface c3 of the cell. When in use, the bottom support plate b is set on the bottom surface a3 to strengthen the structural strength of the bottom surface a3. The existing coating film body needs to be processed separately before being put into use in the cell coating equipment, resulting in low production efficiency and difficulty in adapting to production needs.

DETAILED DESCRIPTION

[0043] In order to better understand and implement, the technical solutions in the embodiments of the present application will be clearly and completely described in the following with reference to the drawings in the embodiments of the present application.

[0044] In the description of the present application, it should be pointed out that the terms "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer" and the like indicate the orientation or positional relationship shown in the drawings, and are only for the purpose of facilitating the description of the present application and simplifying the description, and do not indicate or imply that the devices or elements referred to must have a particular orientation, be constructed and operated in a particular orientation, therefore it cannot be understood as a limitation on the present application.

[0045] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which the present application belongs. The terms used in the specification of the present application are only for the purpose of describing the specific embodiments of the present application, and are not intended to limit the present application.

[0046] Please refer to Figures 1 to 34, a battery cell coating equipment, including a flipping mechanism 1, a reflow line 2, a feeding mechanism 31, a first transfer mechanism 32, a silo 4, a fourth transfer mechanism 5, a packaging mechanism and a gluing mechanism 02, wherein the flipping mechanism 1, the reflow line 2, the feeding mechanism 31, the first transfer mechanism 32, the silo 4, the fourth transfer mechanism 5, the packaging mechanism and the gluing mechanism 02 are all installed on the frame 01; the feeding mechanism 31 is used to transfer the battery cell to the flipping mechanism 1; the first transfer mechanism 32 is used to transfer the battery cell flipped at the flipping mechanism 1 to the reflow line 2; the silo 4 is used to accommodate the coating film body; the fourth transfer mechanism 5 is used to transfer the coating film body to the first packaging point of the reflow line 2, and coat the coating film body to the large surface c1 and the bottom surface c3 of the battery cell; the packaging mechanism is arranged near the first packaging point, and is used to coat and fix the coating film body to the single battery cell c; the gluing mechanism 02 is arranged along the reflow line 2 and is on the downstream side of the packaging mechanism. In this embodiment, Figure 4 Shown and Figure 5 As shown, the individual cells c to be coated are placed horizontally. To facilitate coating of the individual cells c, the cell coating equipment needs to flip the individual cells c during use. That is, when coated, the bottom portion a3 of the individual cells c is positioned upward along the longitudinal direction Z. This action is achieved by the flipping mechanism 1. The individual cells c are then automatically coated and unloaded on the reflow line 2 using the packaging mechanism. The coordination of these mechanisms enables automated coating of the individual cells c, which is beneficial for improving coating efficiency.

[0047] like Figure 1 、 Figures 5 to 7 As shown, the flip mechanism 1 includes a fixed transfer plate 10 and a movable transfer plate 11. The fixed transfer plate 10 is fixed relative to the return line 2. The movable transfer plate 11 is adjustably mounted on the fixed transfer plate 10. The movable transfer plate 11 can move relative to the fixed transfer plate 10 along a first direction X. A flip assembly 13 and a first driving member 12 are rotatably mounted on the fixed transfer plate 10. The first driving member 12 is used to drive the flip assembly 13 to rotate. The single cell c is fixed to the flip assembly 13. Specifically, as shown in FIG. Figure 5 As shown, the movable plate 11 is slidably connected to the fixed plate 10 via a slide rail and slider assembly. The fixed plate 10 is provided with a cylinder for driving the movable plate 11 to move relative to the fixed plate 10.

[0048] like Figures 5 to 7As shown, the flip assembly 13 includes a flip seat 131 rotatably mounted on the movable plate 11, and the flip seat 131 is provided with a first reference block 132 and a second reference block 134, as well as a first positioning block 133 and a second positioning block 135; the first positioning block 133 is arranged opposite to the first reference block 132, and the first positioning block 133 can approach or move away from the first reference block 132 along the first direction X, the second positioning block 135 is arranged opposite to the second reference block 134, and the second positioning block 135 can approach or move away from the second reference block 134 along the second direction Y; the first direction X is perpendicular to the second direction Y, and the second direction Y is parallel to the rotation axis of the flip seat 131; the single battery cell c is in a space defined by the first reference block 132, the second reference block 134, the first positioning block 133 and the second positioning block 135. More specifically, two supports 14 are provided on the movable plate 11, spaced apart in the second direction Y. The flip seat 131 is rotatably mounted on the supports 14 via bearings. Specifically, the flip seat 131 is rotatably mounted on the movable plate 11 via the supports 14. The first drive member 12 is a motor, mounted on one of the supports 14, with its output shaft drivingly connected to the flip seat 131 to drive its rotation. In this embodiment, the first drive member 12 drives the flip seat 131 to rotate 90 degrees, so that the bottom surface c3 of the battery cell faces upward along the longitudinal direction Z.

[0049] Furthermore, a supporting bar 136 is provided on the flip seat 131. The supporting bar 136 extends along the first direction X. The first reference block 132 is located at one end of the supporting bar 136, and the first positioning block 133 is located at the other end of the supporting bar 136. Correspondingly, the second positioning block 135 is located on one side of the supporting bar 136 in the second direction Y, and the second reference block 134 is located on the other side of the supporting bar 136 in the second direction Y. During use, the single cell c is placed on the supporting bar 136, and a supporting force is provided for the single cell c in the longitudinal direction Z before the single cell c is flipped. That is, after the single cell c is transferred to the flip mechanism 1 by the loading mechanism 31, it is first placed on the supporting bar 136, and finally the positioning block and the reference block cooperate to position and fix the single cell c.

[0050] Specifically, if Figure 6 and Figure 7 As shown, the first positioning block 133 and the second positioning block 135 are both driven by a cylinder mounted on the flip base 131. The first reference block 132 is fixedly mounted on the support bar 136, and the second reference block 134 is fixedly mounted on the flip base 131. Optionally, the support bar 136, the positioning blocks, and the reference blocks are provided in two sets, spaced apart along the second direction Y. This allows processing of two single cells c at a time, improving efficiency.

[0051] The second reference block 134 and / or the second positioning block 135 are provided with positioning grooves into which the single cell c is snapped. The positioning grooves are used to secure the single cell c to prevent it from being separated from the support bar 136, i.e., the flipping mechanism 1, during flipping.

[0052] In some embodiments, as Figure 8 As shown, the first reference block 132 is adjustably arranged on the flip seat 131, and the first reference block 132 can move along the second direction Y. Specifically, the first reference block 132 is slidably connected to the flip seat 131 through a slide rail slider assembly, and the first reference block 132 is driven by a cylinder to move along the second direction Y. It should be noted that, in this embodiment, the bottom surface c3 of the battery cell is attached to the first reference block 132. In this way, when the single battery cell c is flipped to the point where the bottom surface c3 of the battery cell is facing upward along the longitudinal direction Z, the first reference block 132 can be detached from the bottom surface c3 of the battery cell by moving along the second direction Y, thereby creating a space adjustment member for the first transfer mechanism 32 to grab the single battery cell c. It is also worth noting that, in this embodiment, the movable transport plate 11 is driven by a linear module to move relative to the fixed transport plate 10.

[0053] like Figure 9 As shown, in this embodiment, the coating equipment further includes a hot melt mechanism 8, a second transfer mechanism 6, and a third transfer mechanism 7. The second transfer mechanism 6 is used to transfer the insulating film a to the hot melt mechanism 8, and the third transfer mechanism 7 is used to transfer the bottom plate b to the hot melt mechanism 8. The insulating film a and the bottom plate b are heat-fused in the hot melt mechanism 8 to form a coating film body. The fourth transfer mechanism 5 is used to transfer the coating film body from the hot melt mechanism 8 to the first packaging point of the reflow line 2. The battery cell coating equipment herein can heat-fuse the insulating film a and the bottom plate b to form a coating film body, and can effectively improve production efficiency by coordinating with the production rhythm of the reflow line 2 and other mechanisms.

[0054] like Figure 9 and Figure 10 As shown, the second transfer mechanism 6 includes a main adsorption plate 61 and an auxiliary adsorption plate 62. The main adsorption plate 61 and the auxiliary adsorption plate 62 are used to grab the insulating film a. The main adsorption plate 61 is rotatably connected to the auxiliary adsorption plate 62. A second driving member 64 is provided on the main adsorption plate 61. The second driving member 64 is used to drive the auxiliary adsorption plate 62 to rotate relative to the main adsorption plate 61. By rotatably connecting the main adsorption plate 61 and the auxiliary adsorption plate 62, single-sheet grabbing can be achieved in the process of grabbing the insulating film a from the silo 4. Specifically, during use, the main adsorption plate 61 and the auxiliary adsorption plate 62 are first placed in a state parallel to each other. After grabbing the insulating film a, in the process of lifting it upward along the longitudinal direction Z, the auxiliary adsorption plate 62 is driven to rotate relative to the main adsorption plate 61 by the second driving member 64, thereby breaking the vacuum adsorption force between the grabbed insulating film a and the adjacent insulating film a, thereby achieving precise grabbing of a single insulating film a at a time.

[0055] In some embodiments, both the main adsorption plate 61 and the auxiliary adsorption plate 62 may be provided with a first negative pressure hole, which is externally connected to a negative pressure generator to generate negative pressure. In other embodiments, the main adsorption plate 61 and the auxiliary adsorption plate 62 may also be provided with a first suction cup 60, which is externally connected to a negative pressure generator to generate negative pressure.

[0056] In this embodiment, the main adsorption plate 61 and the auxiliary adsorption plate 62 are rotatably connected via a hinge 63. A second driving member 64 is preferably a cylinder, one end of which is hinged to the main adsorption plate 61 and the other end is hinged to the auxiliary adsorption plate 62. The second driving member 64 is located on the back side of the main adsorption plate 61 and the auxiliary adsorption plate 62. The back side of the main adsorption plate 61 and the auxiliary adsorption plate 62 is the side that faces away from the insulating film a during operation.

[0057] like Figure 3a As shown, the insulating film a includes two large portions a1, and the two large portions a1 are symmetrically arranged about the bottom portion a3. Based on this, in this embodiment, as shown in FIG. Figure 10 As shown, there are two main adsorption plates 61. The two main adsorption plates 61 are used to correspond to the two large surface areas a1.

[0058] Furthermore, the second transfer mechanism 6 also includes an integrated plate 65 and a mold-removing pressing plate 67. The main adsorption plate 61 is fixedly assembled to the integrated plate 65, and the integrated plate 65 is adjustably arranged relative to the hot melt mechanism 8. The mold-removing pressing plate 67 is located between the two main adsorption plates 61, and the mold-removing pressing plate 67 can abut against or detach from the insulating film a. In this embodiment, the main adsorption plate 61 is fixedly assembled to the integrated plate 65 through a connecting column 68. A third driving member 662 is configured on the integrated plate 65. Preferably, the third driving member 662 is a cylinder, which is fixedly mounted on the integrated plate 65, and the mold-removing pressing plate 67 is mounted on the telescopic end of the third driving member 662 and is driven by the third driving member 662. During use, when the second transfer mechanism 6 grabs the insulating film a to the hot melt mechanism 8, the third driving member 662 acts on the mold-removing pressing plate 67 to press the insulating film a to the hot melt mechanism 8 to ensure that the insulating film a is smoothly detached from the first suction cup 60.

[0059] like Figure 1 、 Figure 9 and Figure 10 As shown, a first support beam 011 is mounted on the frame 01. The second transfer mechanism 6 and the third transfer mechanism 7 are both mounted on the first support beam 011 via linear modules, enabling movement in the second direction Y. In this embodiment, the silo 4 is located on one side of the first support beam 011 along the first direction X, and the hot melt mechanism 8 is positioned adjacent to the silo 4. This arrangement facilitates rapid heat-melting of the insulating film a and the bottom support plate b at the hot melt mechanism 8 to form a coated film.

[0060] In this embodiment, the second transfer mechanism 6 further includes a first linear module 66. The third driving member 662 is mounted on the first linear module 66 via an adapter plate 661 and is driven by the first linear module 66 to enable the third driving member 662, i.e., the integrated plate 65, to move in the longitudinal direction Z. The first linear module 66 is driven by the linear module mounted on the first support beam 011 to move in the second direction Y.

[0061] The third transfer mechanism 7 includes a hot melt press plate 71, which is used to transfer the bottom support plate b to the hot melt mechanism 8. The hot melt press plate 71 can extend to the area between the two main adsorption plates 61 and drive the bottom support plate b close to or away from the insulating film a on the main adsorption plate 61. During use, the second transfer mechanism 6 cooperates with the third transfer mechanism 7. Specifically, the second transfer mechanism 6 fixes the insulating film a to the hot melt mechanism 8, and the third transfer mechanism 7 transfers the bottom support plate b to between the two main adsorption plates 61 through the hot melt pressure plate 71 to correspond to the bottom surface a3, and presses the bottom support plate b tightly to the bottom surface a3. At this time, the hot melt mechanism 8 acts on the insulating film a and the bottom support plate b to hot-melt the two into one to form a coating film body. Then the hot melt pressure plate 71 is separated from the bottom support plate b, and the molding plate 67 is taken to press the bottom support plate b of the coating film body. The first suction cup 60 is separated from the insulating film a that is separated from the coating film body along the longitudinal Z-upward direction, and finally the molding plate 67 is taken to separate from the coating film body along the longitudinal Z-upward direction.

[0062] In this embodiment, a second suction cup 711 is disposed on the hot melt pressing plate 71 . The second suction cup 711 is externally connected to a negative pressure generator for generating negative pressure to grasp the bottom support plate b.

[0063] like Figure 11 As shown, the third transfer mechanism 7 also includes a second linear module 72, which is driven by a linear module arranged on the first support beam 011 to move in the second direction Y. The second linear module 72 is equipped with a transition profile 73, which is driven by the second linear module 72 to move in the longitudinal direction Z. The transition profile 73 is provided with an extension plate 74, which is extended in the second direction Y. The extension plate 74 is provided with a fourth drive member 75. The hot melt pressure plate 71 is installed on the extension plate 74 through the fourth drive member 75 and is driven by the fourth drive member 75 to move in the longitudinal direction Z. The extension plate 74 here creates conditions for the hot melt pressure plate 71 to extend between the two main adsorption plates 61. Specifically, through the structural design of the extension plate 74, the hot melt pressure plate 71 deviates from the main structure of the third transfer mechanism 7 in the second direction Y. In this way, the interference between the second transfer mechanism 6 and the third transfer mechanism 7 can be effectively avoided during the cooperation process.

[0064] Optionally, the fourth driving member 75 is a cylinder, which cooperates with the second linear module 72 to quickly and accurately adjust the position of the hot melt pressing plate 71 in the longitudinal direction Z.

[0065] like Figure 12 As shown, the hot melt mechanism 8 includes a hot melt platform 82 and a third linear module 81 arranged on the frame 01. The hot melt platform 82 is arranged on the third linear module 81 and is driven by the third linear module 81 to move along the second direction Y to adjust the spatial position of the hot melt platform 82 relative to the third transfer mechanism 7 and the fourth transfer mechanism 5 in the second direction Y, so as to facilitate the hot melt formation of the coating film body and the fourth transfer mechanism 5 to grab the coating film body from the hot melt mechanism 8.

[0066] The shape of the hot melt platform 82 is adapted to the shape of the coating film body. A hot fuse 822 is configured on the hot melt platform 82 at a position corresponding to the bottom portion a3 or the bottom support plate b, which is used to heat the bottom support plate b and the insulating film a to hot-melt the two into one.

[0067] The hot melt platform 82 is provided with a third suction cup 821 , which is used to absorb and fix the insulating film a.

[0068] like Figures 13 to 18 As shown, the silo 4 includes a first silo portion 41, a second silo portion 42, a first lifting portion 43, and a second lifting portion 44, wherein: a plurality of insulating films a are stacked in the first silo portion 41, and a plurality of bottom support plates b are stacked in the second silo portion 42; the first lifting portion 43 is arranged corresponding to the first silo portion 41, and is used to lift the insulating films a close to the second transfer mechanism 6; the second lifting portion 44 is arranged corresponding to the second silo portion 42, and is used to lift the bottom support plates b close to the third transfer mechanism 7. In this embodiment, the silo 4 and the lifting portion are both mounted on the frame 01. This arrangement allows the insulating films a and bottom support plates b to be hot-melted in real time to form a coating film body during the production process, and then immediately put into the production of the coating of the single battery cell c. In other words, the battery cell coating equipment can integrate the two working processes of coating film body processing and single battery cell c coating, and rationally match the two to ensure the production rhythm, thereby achieving the purpose of improving work efficiency.

[0069] like Figure 16 As shown, the first storage portion 41 includes a first base plate 410, on which a first lifting plate 411 is stacked. A plurality of first retaining posts 4101 are disposed around the first base plate 410. The first lifting plate 411 is located within the area defined by the plurality of first retaining posts 4101. Several insulating films a are stacked on the first lifting plate 411. The first lifting portion 43 acts on the first lifting plate 411, causing the first lifting plate 411 and the insulating films a to move synchronously toward the second transfer mechanism 6. In this embodiment, four first retaining posts 4101 are arranged in a ring around the first lifting plate 411 to limit the position of the insulating films a on the first lifting plate 411.

[0070] Furthermore, the first bottom plate 410 is provided with positioning pins 412 extending in the longitudinal direction Z. The positioning pins 412 penetrate the first lifting plate 411 and penetrate the plurality of insulating films a on the first lifting plate 411. The positioning pins 412 are used to further position the insulating films a, ensuring that the insulating films a on the first lifting plate 411 are neatly stacked and easily grasped by the second transfer mechanism 6.

[0071] In this embodiment, a first stopper 41011 is provided on the first stopper column 4101. The orthographic projection of the first stopper 41011 on the first lifting plate 411 is at least partially within the range of the insulating film a. The first stopper 41011 is capable of breaking the vacuum of the insulating film a adjacent to the topmost insulating film a during the process of the topmost insulating film a being removed from the first chamber portion 41, thereby ensuring that only a single insulating film a is captured at a time. More importantly, when the first lifting portion 43 acts on the first lifting plate 411 to move upward in the longitudinal direction Z, the first lifting plate 411 is limited in position.

[0072] Furthermore, the first stopper 41011 is slidably connected to the corresponding first stopper column 4101, and a first damping member 41012 is provided between the first stopper 41011 and the corresponding first stopper column 4101 to provide a damping force for the first stopper 41011 in the process of approaching the second transfer mechanism 6 along the longitudinal direction Z. Figure 16 As shown, the first damping member 41012 is optionally a spring. The first damping member 41012 is pressed between the first stopper 41011 and the first stopper post. The first stopper 41011 is slidably connected to the first stopper post via a slide rail and slider assembly. The first damping member 41012 can provide a buffer when the first lifting plate 411 strikes the first stopper 41011, preventing hard contact.

[0073] The first base plate 410 is provided with a second stopper 4102, which is equipped with a brush 41021. The orthographic projection of the brush 41021 on the first lifting plate 411 is at least partially within the range of the insulating film a. The brush 41021 prevents the lower insulating film a from adhering to the upper insulating film a and following it out of the first chamber 41 as the upper insulating film a is removed from the first chamber 41. Specifically, when the lower insulating film a passes by the brush 41021, it is blocked by the brush 41021 and falls back into the first chamber 41.

[0074] like Figure 16 and Figure 17As shown, the first lifting portion 43 includes a first driving mechanism 432 and a first driving head 435. The first driving head 435 is provided with a first clamping portion 436. The first lifting plate 411 is provided with a second clamping portion 41111 that cooperates with the first clamping portion 436. The first driving mechanism 432 is used to drive the first driving head 435 so that the first clamping portion 436 abuts against or disengages from the second clamping portion 41111. In this embodiment, the first driving mechanism 432 is mounted on the frame 01 through the first mounting plate 431, and a plurality of first driving heads 435 are integrated on the first push plate 434. Accordingly, the first base plate 410 is provided on the frame 01 and is located above the first lifting portion 43. Figure 17 As shown, the first lifting plate 411 is provided with a drive column 4111, which extends downward along the longitudinal direction Z through the first base plate 410. The multiple drive columns 4111 are arranged in a one-to-one correspondence with the multiple first drive heads 435. Preferably, the first driving mechanism 432 is a screw stepper motor, and the first push plate 434 is provided with a first guide rod 433, which extends through the first mounting plate 431 and is slidably connected thereto. The first guide rod 433 extends along the longitudinal direction Z. During use, the first driving mechanism 432 drives the first push plate 434 to move upward along the longitudinal direction Z. During this process, the first drive head 435 approaches the drive column 4111 in the longitudinal direction Z until the first clamping portion 436 is clamped to the second clamping portion 41111. Then, the first driving mechanism 432 continues to function, realizing continuous upward movement of the first lifting plate 411 in the longitudinal direction Z.

[0075] In this embodiment, the first clamping portion 436 is a protruding structure, and the second clamping portion 41111 is a recessed structure adapted to the shape of the first clamping portion 436. This arrangement can ensure the structural stability of the first lifting plate 411 when it moves along the longitudinal direction Z.

[0076] like Figure 18 As shown, the second storage unit 42 includes a second bottom plate 420 and a second lifting plate 421. The second bottom plate 420 is provided with a guide post 422, which is provided with a guide groove 4221. The second lifting plate 421 is slidably embedded in the guide groove 4221. The bottom support plate b is stacked on the second lifting plate 421, and the second lifting portion 44 acts on the second lifting plate 421, so that it can slide along the guide groove 4221 to approach the third transfer mechanism 7. In this embodiment, the second bottom plate 420 is disposed on the frame 01 and above the second lifting portion 44. The second bottom plate 420 is provided with a driving hole 4201, through which the second lifting portion 44 acts on the second lifting plate 421. The guide groove 4221 here is used to guide the movement of the second lifting plate 421 in the longitudinal direction Z to ensure its structural stability.

[0077] Furthermore, a limit plate 423 is slidably mounted on the guide post 422 via a slide rail and slider assembly. The limit plate 423 at least partially extends into the guide slot 4221 and is located along the upward motion path of the second lifting plate 421 in the longitudinal direction Z. A second damping member 424 is disposed between the limit plate 423 and the guide post 422 to provide a damping force as the limit plate 423 approaches the third transfer mechanism 7 in the longitudinal direction Z. The limit plate 423 prevents the second lifting plate 421 from disengaging from the guide slot 4221 in the longitudinal direction Z. The second damping member 424 provides a buffering force for the second lifting plate 421 when the second lifting plate 421 abuts the limit plate 423, preventing hard contact between the second lifting plate 421 and the limit plate 423. Preferably, the second damping member 424 is a spring.

[0078] like Figure 18 As shown, the second lifting portion 44 includes a second mounting plate 440, a second driving mechanism 441, and a second push plate 443. The second mounting plate 440 is assembled to the frame 01, and the second push plate 443 is slidably mounted on the second mounting plate 440 via a second guide rod 442. The second driving mechanism 441 is provided on the second mounting plate 440 and is used to drive the second push plate 443 toward or away from the second lifting plate 421 along the longitudinal direction Z. The second driving mechanism 441 is a screw stepping motor.

[0079] like Figure 14 and Figure 15 As shown, the silo 4 also includes a guide plate 45 and a drawer plate 46. The first lifting portion 43 and the second lifting portion 44 are located below the drawer plate 46. The first bin portion 41 and the second bin portion 42 are mounted on the drawer plate 46, and the drawer plate 46 is slidably connected to the guide plate 45. Specifically, the drawer plate 46 and the guide plate 45 are slidably connected via a slide rail and slider assembly. In this embodiment, the first bottom plate 410 and the second bottom plate 420 are both mounted to the frame 01 via a sliding connection structure between the drawer plate 46 and the guide plate 45, and the guide plate 45 is mounted to the frame 01. The drawer plate 46 can move relative to the guide plate 45 in a first direction X. This makes it convenient for workers to pull out the first bin portion 41 and the second bin portion 42 to replenish the insulating film a and the bottom support plate b during operation.

[0080] Optionally, there may be two or more drawer panels 46 , and two adjacent drawer panels 46 are also slidably connected via a slide rail and slider assembly to increase the pulling stroke of the first bin portion 41 and the second bin portion 42 in the first direction X.

[0081] In this embodiment, the first and second compartments 41, 42 are both mounted on a carrier plate 47. The drawer panels 46 and guide rails 45 are provided with two sliding connection structures spaced apart from each other, with the carrier plate 47 spanning between the two sliding connection structures. It should be noted that the carrier plate 47 is provided with holes to allow the first and second lifting portions 43, 44 to pass through the carrier plate 47 and reach the first and second compartments 41, 42, respectively, during operation.

[0082] like Figure 9 、 Figures 19 to 21 As shown, the fourth transport mechanism 5 includes a fixed plate 53 and a fifth drive member 54. A flipping and grabbing portion 55 is rotatably mounted on the fixed plate 53. The flipping and grabbing portion 55 is arranged corresponding to the large surface a1 of the insulating film a. The flipping and grabbing portion 55 is used to grab the insulating film a on the hot melt mechanism 8. The fifth drive member 54 is used to drive the flipping and grabbing portion 55 to flip so that the large surface a1 is attached to the large surface c1 of the battery cell. As mentioned above, after the single battery cell c is flipped by the flipping mechanism 1, the bottom surface c3 of the single battery cell c on the return line 2 faces upward. Here, the fourth transport mechanism 5 grabs the film body of the coating to the return line 2 and places the film body above the bottom surface c3 of the battery cell. At this time, the fifth drive member 54 drives the flipping and grabbing portion 55 to make the large surface a1 correspondingly attached to the large surface c1 of the battery cell.

[0083] Preferably, the fifth driving member 54 is a motor, which is mounted on the fixing plate 53 and is transmission-connected to the flipping and grabbing portion 55 .

[0084] In this embodiment, the flipping and grasping portion 55 includes a negative pressure plate 551 rotatably mounted on the fixed plate 53, and the negative pressure plate 551 is provided with a second negative pressure hole for adsorbing the coating membrane body. Furthermore, a film pressing block 552 and a mounting frame 553 are provided on the negative pressure plate 551, and a plane rotary clamping cylinder 5531 is provided on the mounting frame 553. The plane rotary clamping cylinder 5531 corresponds to the four vertex corners of the coating membrane body and is used to grasp the four vertex corner areas of the coating membrane body. The plane rotary clamping cylinder 5531 clamping the coating mold body is a prior art and will not be described in detail here. The film pressing block 552 here is used to press the coating mold body to the large surface c1 of the battery cell during the process of the coating membrane body being attached to the large surface c1 of the battery cell.

[0085] In another embodiment, the film pressing block 552 and the mounting frame 553 may also be equipped with a negative pressure structure to grasp and fix the film body by negative pressure adsorption. It should be noted that in this embodiment, the mounting frame 553 is no longer equipped with a flat rotary clamping cylinder 5531.

[0086] like Figure 20 and Figure 21As shown, two fixed plates 53 are included in the embodiment, corresponding to two turnover gripping parts 55, the two fixed plates 53 are fixedly installed on a large plate 57, a buffer plate 56 is adjustably arranged on the large plate 57, and a first buffer spring is arranged between the buffer plate 56 and the large plate 57. The buffer plate 56 is between the two turnover gripping parts 55 and corresponds to the bottom surface part a3. In use, the buffer plate 56 is used to press and fit the bottom surface part a3, that is, the bottom supporting plate b area of the film mold, to the bottom surface c3 of the battery cell, and prevent the fourth transfer mechanism 5 from hard contact with the monomer battery cell c in the process.

[0087] As shown in Figure 9 and Figure 19 , the fourth transfer mechanism 5 further includes a fourth linear module 51, and the large plate 57 is installed on the fourth linear module 51 through an extension frame 52 and is driven by the fourth linear module 51 to move along the longitudinal direction Z. A second support beam 012 is arranged on the rack 01, and the fourth linear module 51 is installed on the second support beam 012 through a linear module and is driven by the linear module to move along the first direction X to approach or move away from the return flow line 2.

[0088] As shown in Figures 22 to 25 , a clamp 21 is arranged on the return flow line 2, the clamp 21 includes a supporting plate 210, two clamping jaws 212 are slidingly assembled on the supporting plate 210, and the clamp 21 further includes a driving part arranged on the supporting plate 210, the driving part acts on the two clamping jaws 212 to make them approach or move away from each other, and the monomer battery cell c is between the two clamping jaws 212. Specifically, as shown in Figure 24 and Figure 25 , the clamping jaw 212 includes a longitudinal plate 2121 slidingly connected with the supporting plate 210, a pressing block 2122 is arranged on the longitudinal plate 2121, a relief groove 21221 is arranged on the pressing block 2122, extends along the longitudinal direction Z and penetrates through the pressing block 2122, and when the monomer battery is clamped in the clamp 21, the relief groove 21221 is communicated to the side surface c2 of the battery cell. The relief groove 21221 here facilitates the later gluing of the film mold.

[0089] The driving part includes a driving plate 213 slidingly arranged on the supporting plate 210, the driving plate 213 is provided with a driving inclined groove 2131, and the longitudinal plate 2121 is slidingly embedded in the driving inclined groove 2131. As shown in Figure 25 , when the driving plate 213 moves along the first direction X, the driving inclined groove 2131 acts on the longitudinal plate 2121 to make it move along the second direction Y. In the embodiment, the included angle between the driving inclined groove 2131 and the first direction X is an acute angle.

[0090] Preferably, a limiting block 2101 is arranged on the supporting plate 210, and a locking spring 214 is arranged between the limiting block 2101 and the driving plate 213, so that the clamp 21 always has a tendency to keep the locking state.

[0091] In this embodiment, the longitudinal plate 2121 and the driving plate 213 are both slidably connected to the supporting plate 210 via a slide rail and slider assembly.

[0092] like Figure 23 and Figure 24 As shown, a reference plate 211 is provided on the support plate 210, the reference plate 211 is located between two clamping jaws 212, and the driving unit is located between the reference plate 211 and the support plate 210. When in use, the single cell c is placed on the reference plate 211, specifically, the top cover c4 abuts against the reference plate 211.

[0093] The drive plate 213 is provided with an unlocking block 2132, and the return line 2 is provided with a first unlocking plate 22. The first unlocking plate 22 is driven toward or away from the unlocking block 2132 by the unlocking cylinder 221. During use, when unlocking is required, the unlocking cylinder 221 drives the first unlocking plate 22 to abut against the unlocking block 2132, thereby moving the drive plate 213 in the first direction X, compressing the locking spring 214, and unlocking the clamp 21.

[0094] like Figure 22 、 Figure 23 、 Figure 26 and Figure 27 As shown, a long-side hot melt assembly 23 is provided at the first packaging point on the reflow line 2. The long-side hot melt assembly 23 includes a first fixed plate 232 provided on the side of the fixture 21. A first movable plate 233 is adjustably provided on the first fixed plate 232. The first movable plate 233 is provided with a long-side hot melt block 231. The first movable plate 233 can move closer to or away from the fixture 21 along the first direction X relative to the first fixed plate 232. During use, after the fourth transfer mechanism 5 wraps the coating film body on the large surface c1 of the battery cell, the first movable plate 233 moves toward the fixture 21, that is, the single battery cell c, so that the long-side hot melt block 231 abuts against the large surface a1, so that the large surface a1 is hot-melted and connected to the large surface c1 or the top cover c4 of the battery cell.

[0095] In this embodiment, the first movable plate 233 and the first fixed plate 232 are slidably connected by a slide rail and slider assembly. There may be two or more first movable plates 233, and two adjacent first movable plates 233 are also slidably connected by the slide rail and slider assembly to increase the movement range of the long-side hot melt block 231 in the first direction X. The first movable plate 233 is driven by a cylinder.

[0096] like Figure 22 、 Figure 23 、 Figures 28 to 31As shown, a short-side hot melt assembly 24 is also provided downstream of the first packaging point on the reflow line 2, for hot-melting and fixing the side portion a2 to the side c2 of the battery cell. Specifically, the short-side hot melt assembly 24 includes a column 241 provided on the frame 01, with a top plate 242 provided at the top of the column 241. The top plate 242 is provided with an auxiliary fixture 245. When the clamp 21 is in the unlocked state, the auxiliary fixture 245 is used to clamp the single battery cell c on the clamp 21; the column 241 is provided with a side film pressing mechanism, which acts on the side portion a2 to make it adhere to the side c2 of the battery cell; and the column 241 is adjustable with a short-side hot melt block 246, which is used to hot-melt the side portion a2 to the side c2 of the battery cell.

[0097] The side pressing mechanism includes a first mounting block 244, which is fixedly mounted to the column 241. Two clamping plates 2441 are adjustably provided on the first mounting block 244. The two clamping plates 2441 can move closer to or farther from each other, and both clamping plates 2441 can move closer to or farther from the clamp 21 along the first direction X. The clamping plates 2441 correspond to the side surface c2 of the battery cell, and a notch 24411 is provided on the clamping plates 2441 to avoid the pressing block 2122. Figure 23 and Figure 31 As shown, when in use, the clamp 2441 moves along the first direction X toward the clamp 21. During this process, the pressure plate acts on the side portion a2 to bend it toward the side c2 of the battery cell. Then the two clamps 2441 approach each other along the second direction Y to press the side portion a2 tightly to the side c2 of the battery cell. At this time, the short side hot melt block 246 acts on the side c2 of the battery cell to hot-melt the side portion a2 to the side c2 of the battery cell. It should be noted that the two side pressing mechanisms are symmetrically arranged about the clamp 21 to complete the pressing and fitting of a total of four side portions a2 of the side c2 of the two battery cells. It should be noted that during this process, the clamp 21 is in an unlocked state, and the single battery cell c is fixed by the auxiliary fixture 245. The auxiliary fixture 245 here acts on the large surface c1 of the battery cell.

[0098] Specifically, if Figure 31 As shown, the side film pressing mechanism also includes a transition plate 2442, which is driven by a cylinder arranged on the first mounting block 244 to move along the first direction X, and the two clamping plates 2441 are slidably installed on the transition plate 2442 through a slide rail slider assembly, and the two clamping plates 2441 are driven by a cylinder installed on the transition plate 2442 to move closer to or away from each other along the second direction Y.

[0099] like Figure 23 、 Figure 28 and Figure 29As shown, the column 241 is equipped with a second mounting block 243, which is located below the first mounting block 244. The second mounting block 243 is provided with a second unlocking plate 2431 and a short side heat-melting block 246. More specifically, as shown in FIG. Figure 29 As shown, the short side heat melting block 246 is adjustably set on the second mounting block 243 in the first direction X and the second direction Y respectively through the slide rail slider assembly and the cylinder. There are two short side heat melting blocks 246, corresponding to the side c2 of the battery cell. A second unlocking plate 2431 is set between the two short side heat melting blocks 246. The second unlocking plate 2431 is driven by the cylinder set on the second mounting block 243 to cooperate with the unlocking block 2132 to unlock the clamp 21.

[0100] like Figure 28 and Figure 30 As shown, the auxiliary fixture 245 includes a finger cylinder 2451 and an auxiliary claw 2452 provided on the top plate 242 . The two auxiliary claws 2452 are driven by the finger cylinder 2451 to move closer to or away from each other.

[0101] In this embodiment, the long-side hot-melt assembly 23 , the short-side hot-melt assembly 24 and the side film pressing mechanism together constitute the aforementioned packaging mechanism.

[0102] like Figures 32 to 34 As shown, the gluing mechanism 02 includes a glue supply component 022 and a glue supply component 021. The glue supply component 022 provides a glue paper segment 024 for the glue supply component 021. The glue paper segment 024 includes a top segment 0241 and a side segment 0242 that are connected to each other. The glue supply component 021 includes a top glue head 0214 and a side glue head 0213. The top glue head 0214 is used to grab the top segment 0241 to fit the top segment 0241 to the bottom surface c3 of the battery cell. The side glue head 0213 is used to grab the side segment 0242 to fit the side segment 0242 to the side surface c2 of the battery cell. The side glue head 0213 can be flipped relative to the top glue head 0214. In this embodiment, after the coating film body on the single cell c is processed by the long-side hot melt block 231 and the short-side hot melt block 246, it needs to be further fixed to improve its firmness. The single cell c follows the fixture 21 and is transported to the gluing mechanism 02 through the reflow line 2. First, the top segment 0241 is glued to the bottom surface c3 of the cell, that is, the bottom support plate b of the coating film body, through the top glue head 0214. Then, the side glue head 0213 is flipped relative to the top glue head 0214 to glue the side segment 0242 to the side c2 of the cell to complete the gluing.

[0103] In this embodiment, a third negative pressure hole is provided on both the top glue head 0214 and the side glue head 0213 . The third negative pressure hole is connected to a negative pressure generator to generate negative pressure for adsorbing and grabbing the adhesive paper segment 024 .

[0104] Furthermore, the top adhesive head 0214 is configured with a first working plane 02140, and the side adhesive head 0213 is configured with a second working plane 02130. Third negative pressure holes are provided within the first and second working planes 02140 and 02130, and the second working plane 02130 is not higher than the first working plane 02140. This arrangement ensures that after the side adhesive head 0213 is flipped over, the adhesive tape section 024 does not wrinkle at the transition between the bottom surface c3 and the side surface c2 of the battery cell.

[0105] like Figure 32 and Figure 33 As shown, the adhesive application assembly 021 further includes a frame plate 023 and an adjustment plate 0212. The adjustment plate 0212 is slidably mounted on the frame plate 023. The side adhesive head 0213 is rotatably mounted on the end of the adjustment plate 0212 away from the frame plate 023. The adjustment plate 0212 is provided with a sixth driving member 0211 for driving the side adhesive head 0213 to rotate. Optionally, the sixth driving member 0211 is a cylinder, one end of which is hinged to the adjustment plate 0212 and the other end of which is hinged to the side adhesive head 0213.

[0106] In this embodiment, a hinge plate 0215 is fixedly mounted on the side rubber head 0213 , and the hinge plate 0215 is rotatably connected to the adjustment plate 0212 via a pin 0216 .

[0107] In this embodiment, the adjustment plate 0212 is slidably mounted on the frame 023 via a slide rail and slider assembly. Specifically, the adjustment plate 0212 can move relative to the frame 023 to move closer to or further from the side surface c2 of the battery cell. Furthermore, the gluing mechanism 02 also includes a third support beam 025 and a fifth linear module 026. The third support beam 025 is mounted on the frame 01, and the fifth linear module 026 is mounted on the third support beam 025. The frame 023 is mounted on the fifth linear module 026 and driven by it to move in the longitudinal direction Z.

[0108] The top rubber head 0214 is slidably installed on the adjustment plate 0212 through the slide rail slider assembly. The adjustment plate 0212 is provided with a second stopper 02142 , and a second buffer spring 02141 is pressed between the top rubber head 0214 and the second stopper 02142 .

[0109] During use, the fifth linear module 026 drives the frame plate 023, namely the top rubber head 0214, and the side rubber head 0213 downward along the longitudinal direction Z, approaching the bottom surface c3 of the battery cell, until the top rubber head 0214 affixes the top segment 0241 to the bottom surface c3 of the battery cell, namely the bottom support plate b. During this process, the second buffer spring 02141 is compressed to provide a buffering effect. Subsequently, the sixth driving member 0211 acts on the side rubber head 0213, causing it to tilt downward 90 degrees. During this process, the adjustment plate 0212 continues to slowly move downward along the longitudinal direction Z and toward the side surface c2 of the battery cell, tightly affixing the side segment 0242 to the side surface c2 of the battery cell, namely the side portion a2. This continued slow downward movement of the adjustment plate 0212 ensures that no wrinkles are formed at the transition between the top segment 0241 and the side segment 0242.
