[0032] The embodiments of the present invention are described in detail below, and examples of the embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements having the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and cannot be understood as limiting the present invention.

[0033] In the description of the present invention, it should be understood that descriptions involving orientation, such as up, down, front, back, left, right, etc., indicating orientations or positional relationships, are based on the orientations or positional relationships shown in the accompanying drawings, and are only for the convenience of describing the present invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as a limitation on the present invention.

[0034] In the description of the utility model, if there is a description of first and second, it is only for the purpose of distinguishing the technical features, and cannot be understood as indicating or implying the relative importance or implicitly indicating the number of the indicated technical features or implicitly indicating the order of the indicated technical features.

[0035] In the description of the present invention, unless otherwise clearly defined, terms such as setting, installing, connecting, etc. should be understood in a broad sense, and technicians in the relevant technical field can reasonably determine the specific meanings of the above terms in the present invention based on the specific content of the technical solution.

[0036] The following is combined with Figure 1-5 This application is described in further detail.

[0037] The embodiment of the utility model provides a battery cell tail glue sticking device, referring to Figure 1 and Figure 2 , including a base plate 100 and a glue supply mechanism, a moving mechanism and a transmission mechanism arranged in sequence along the transmission direction of the tape 200. The base plate 100 is arranged vertically, and the glue supply mechanism, the moving mechanism and the transmission mechanism are all arranged on the base plate 100. The glue supply mechanism is used to provide the tape 200 to the battery cell, the moving mechanism provides kinetic energy for the transmission of the tape 200, and the transmission mechanism is used to adhere the tape 200 to the battery cell. When the tape 200 needs to be pasted, the tape 200 of the glue supply mechanism is driven by the moving mechanism to move to the transmission mechanism, and the tape 200 is adhered to the battery cell through the transmission mechanism, thereby realizing the pasting of the tape 200.

[0038] It is understandable that in some embodiments of the present invention, reference Figure 1 and Figure 2 The glue supply mechanism includes a winding wheel 310 and a cache component. The winding wheel 310 is arranged on one side of the bottom plate 100. The winding wheel 310 is used to wind the adhesive tape 200. The cache component can pull the adhesive tape 200 on the winding wheel 310 to drive the winding wheel 310 to rotate, thereby caching the adhesive tape 200.

[0039] Specifically, refer to Figure 2 and Figure 3The cache assembly includes a first cylinder 321, a slider 322, a first slide rail 323, a transmission wheel 324, and two first tension wheels 325. The first slide rail 323 is vertically arranged on the bottom plate 100, and the slider 322 slides with the first slide rail 323. The cylinder seat of the first cylinder 321 is arranged on the bottom plate 100 and is located below the first slide rail 323. The piston rod of the first cylinder 321 is connected to the slider 322, so that the first cylinder 321 can drive the slider 322 to slide relative to the first slide rail 323. The two first tension wheels 325 are rotatably arranged on the bottom plate 100 and are located on both sides of the first slide rail 323. The first tension wheels 325 correspond to the bottom position of the first slide rail 323. The transmission wheel 324 is rotatably arranged on the slider 322. The adhesive tape 200 passes through one of the first tension wheels 325, the transmission wheel 324 and the other first tension wheel 325 in sequence, so that the adhesive tape 200 on the two first tension wheels 325 is respectively connected to the winding wheel 310 and the moving mechanism, so that the slider 322 is driven by the first cylinder 321 to slide relative to the first slide rail 323 to drive the transmission wheel 324 to rise, so that the transmission wheel 324 and the two first tension wheels 325 are staggered in the horizontal direction, so that the transmission wheel 324 and the two first tension wheels 325 can cooperate to apply tension to the adhesive tape 200 to increase the friction between the adhesive tape 200 and the transmission wheel 324; and because the moving mechanism exerts tension on the adhesive tape on one of the first tension wheels 325 When the first and second tension wheels 325 are in contact with each other, the first and second tension wheels 325 are in contact with each other, and the first and second tension wheels 325 are in contact with each other, so that the adhesive tape 200 of the adhesive tape 200 is gradually increased.

[0040] In some related technologies, the adhesive tape 200 of the winding wheel 310 is directly connected to the moving mechanism, and the moving mechanism cannot directly pull the winding wheel 310 to rotate through the adhesive tape 200. Therefore, it is necessary to set an active motor on the winding wheel 310 to drive the winding wheel 310 through the active motor to achieve the function of supplying adhesive. However, setting an active motor on the winding wheel 310 increases the equipment cost and is not conducive to mass production. In this embodiment, referring to Figure 1 and Figure 2By providing a buffer component to replace the active motor, the equipment cost is saved and the tension of the tape 200 is increased, making the transmission of the tape 200 more accurate.

[0041] It is understandable that in some embodiments of the present invention, reference Figure 1 and Figure 4 The moving mechanism includes a clamping assembly and a driving assembly. The clamping assembly can be located at a first position and a second position. When the clamping assembly is located at the first position, the clamping assembly can clamp the end of the tape 200. The driving assembly can drive the clamping assembly to move to the second position, thereby transferring the tape 200 to the transmission mechanism. In this embodiment, the first position and the second position are distributed along the horizontal direction of the bottom plate 100.

[0042] It is understandable that in some embodiments of the present invention, reference Figure 1 and Figure 4 The clamping assembly includes a lower pressing block 411, an upper pressing block 412 and a second cylinder 413. The lower pressing block 411 is horizontally connected to the bottom plate 100. The second cylinder 413 is connected to the bottom plate 100 and is located above the lower pressing block 411. The upper pressing block 412 is fixedly connected to the piston rod of the second cylinder 413. The second cylinder 413 is used to drive the upper pressing block 412 to press against the lower pressing block 411. The adhesive tape 200 is inserted between the upper pressing block 412 and the lower pressing block 411. In some embodiments, the upper pressing plate is provided with a serration 4121, and the serration 4121 is used to abut against the adhesive tape 200. Since the end surface of the adhesive tape 200 close to the upper pressing block 412 is an adhesive surface, the contact area between the upper pressing block 412 and the adhesive tape 200 can be reduced by the serration 4121, thereby reducing the impact on the adhesive surface.

[0043] It is understandable that in some embodiments of the present invention, reference Figure 1 and Figure 5The driving assembly includes a second slide rail 421, a first slide plate 422, a first motor 423, a first synchronous belt 424, a first synchronous wheel 425, a screw 426 and a connecting block. The second slide rail 421 is horizontally arranged on the base plate 100, and the first slide plate 422 slides with the second slide rail 421. The clamping assembly is arranged on the first slide plate 422 so that the first slide plate 422 can drive the clamping assembly to move relative to the first slide rail 323. The first motor 423 is arranged on the base plate 100, and the screw 426 is rotatably arranged on the base plate 100 along the length direction of the second slide rail 421. The first synchronous wheel 425 is fixedly connected to one end of the screw 426, and the first synchronous belt 424 is arranged between the output end of the first motor 423 and the first synchronous wheel 425. One end of the connecting block is connected to the first slide plate 422, and the other end is penetrated by a screw hole, and the screw hole is threadedly matched with the screw 426. When it is necessary to drive the clamping assembly to move, the first synchronous belt 424 is driven to rotate by the first motor 423, thereby driving the screw 426 to rotate, and then the connecting block is moved along the length direction of the screw 426 through the screw hole and the screw 426. The first slide plate 422 slides relative to the second slide rail 421, thereby driving the clamping assembly to move.

[0044] It is understandable that in some embodiments of the present invention, reference Figure 1 , Figure 4 and Figure 6 The transmission mechanism includes a positioning component and an adsorption roller 520. The positioning component is located at the second position, and the positioning component can drive the tape 200 to abut against the adsorption roller 520. The adsorption roller 520 is hollow, and a plurality of through holes 521 are provided on the periphery of the adsorption roller 520. The through holes 521 are connected to the interior of the adsorption roller 520. The interior of the adsorption roller 520 is in a negative pressure state, so that when the clamping component moves the tape 200 to the second position, the positioning component can abut against the tape 200, and make the tape 200 abut against the adsorption roller 520, so that the tape 200 is positioned between the positioning component and the adsorption roller 520, and the negative pressure inside the adsorption roller 520 sucks air into the through holes 521, so that the tape 200 can adhere to the adsorption roller 520, and then the adsorption roller 520 is moved to the battery cell to paste the tape 200.

[0045] It is understandable that in some embodiments of the present invention, reference Figure 2 and Figure 6The positioning assembly includes a second slide plate 511, a third cylinder 512 and abutment block 513. The second slide plate 511 is slidably matched with the second slide rail 421. The third cylinder 512 is arranged on the second slide plate 511. The abutment block 513 is fixedly connected to the piston rod of the third cylinder 512. The third cylinder 512 can drive the abutment block 513 to rise and fall, so as to make the tape 200 abut against the adsorption roller 520. When it is necessary to glue different battery cells, it is necessary to determine the size of the tape 200 according to the size of the different battery cells, so as to slide the second slide plate 511 relative to the second slide rail 421 to drive the abutment block 513 to move, thereby changing the distance between the first position and the second position, so that the distance between the two is consistent with the required length of the tape 200. Correspondingly, when the clamping assembly moves the tape 200 to the second position, the upper pressure plate is separated from the lower pressure plate to loosen the tape 200. At this time, the abutment block 513 is driven by the third cylinder 512 to abut against the tape 200, so that the tape 200 abuts against the adsorption roller 520, and then the negative pressure inside the adsorption roller 520 sucks air into the through hole 521, so that the tape 200 can adhere to the adsorption roller 520, and then the adsorption roller 520 is moved to the battery cell to paste the tape 200, so that the relative position of the tape 200 and the adsorption roller 520 is fixed by the positioning of the abutment block 513 and the adsorption force of the adsorption roller 520, so as to reduce the misalignment of the tape 200 when it adheres to the battery cell, or even the situation where it cannot adhere to the battery cell.

[0046] It is understandable that in some embodiments of the present invention, reference Figure 4 and Figure 6 A contact disc 5131 is provided at one end of the abutment block 513, and the axial direction of the contact disc 5131 is distributed along the length direction of the second slide rail 421, so that the bottom of the contact disc 5131 contacts the tape 200 in a point contact manner. Since the tape 200 is close to the upper end surface as an adhesive surface, the point contact between the contact disc 5131 and the tape 200 can reduce the contact area between the upper abutment block 513 and the tape 200, thereby reducing the impact on the adhesive surface.

[0047] It is understandable that in some embodiments of the present invention, reference Figure 5The transmission mechanism is provided with a rotating assembly, and the rotating assembly is used to rotate the adsorption roller 520 to the battery cell. Specifically, the rotating assembly includes a second motor 531, a connecting rod 532 and a fixing frame 533. The second motor 531 is fixedly connected to the bottom of the bottom plate 100, and the connecting rod 532 is fixedly connected to the output shaft of the second motor 531. The connecting rod 532 is distributed along the length direction of the second slide rail 421. One side of the fixing frame 533 is fixedly connected to the connecting rod 532. The adsorption roller 520 is rotatably arranged on the fixing frame 533. When the adhesive tape 200 abuts against the adsorption roller 520, the connecting rod 532 is driven to rotate by the second motor 531, thereby driving the fixing frame 533 to rotate along the axial direction of the connecting rod 532, and then the adsorption roller 520 is rotated along the axial direction of the connecting rod 532, so as to drive the adhesive tape 200 to the battery cell for pasting.

[0048] It is understandable that in some embodiments of the present invention, reference Figure 5 The rotating assembly also includes a third motor 534, a second synchronous wheel 535, and a second synchronous belt 536. The third motor 534 is fixedly arranged on the fixed frame 533, the second synchronous wheel 535 is fixedly arranged on one end of the adsorption roller 520, and the second synchronous belt 536 is arranged between the output shaft of the third motor 534 and the second synchronous wheel 535. When the tape 200 abuts against the adsorption roller 520, the tape 200 is located above the adsorption roller 520, and when the tape 200 adheres to the battery cell, it needs to adhere from above the battery cell, so that the adsorption roller 520 needs to be rotated, so the third motor 534 drives the second synchronous wheel 535 to rotate through the second synchronous belt 536, thereby driving the adsorption roller 520 to rotate to the required angle, so that the tape 200 adheres to the battery cell.

[0049] It is understandable that in some embodiments of the present invention, reference Figure 1 and Figure 4 The cell tail glue sticking device includes a cutting mechanism, which is movably arranged on the driving assembly. When the tape 200 abuts against the adsorption roller 520, the cutting mechanism can be moved to the first position by the driving assembly to cut the tape 200. Specifically, the cutting mechanism includes a fourth cylinder 610 and a cutter 620. The fourth cylinder 610 is fixedly arranged on the first slide plate 422 and is located on the side of the first cylinder 321 close to the third cylinder 512. The fourth cylinder 610 can drive the cutter 620 to rise and fall, so as to cut the tape 200. When the third cylinder 512 drives the abutment block 513 to abut against the tape 200 to abut the adsorption roller 520, the cutting mechanism is moved to the first position by the driving assembly, so that the cutter 620 is driven down by the fourth cylinder 610 to cut the tape 200, so that the length of the tape 200 after cutting is the distance between the first position and the second position, that is, the length of the tape 200 after cutting corresponds to the size of the cell.

[0050] It is understandable that in some embodiments of the present invention, reference Figure 1 and Figure 2 The suction roller 520 is provided with a pressure sensor 522, which is disposed on the bottom plate 100. The pressure sensor 522 is used to monitor the negative pressure value inside the suction roller 520. When the suction roller 520 rotates along its own axis, the negative pressure value inside the suction roller 520 is continuously monitored by the pressure sensor 522 to ensure that the suction roller 520 applies a suction force to the adhesive tape 200, thereby reducing the situation where the adhesive tape 200 uses its own gravity to separate from the suction roller 520. In some embodiments, the pressure sensor 522 is provided with a display 5221, which is used for the user to read parameters such as the negative pressure value.

[0051] It is understandable that in some embodiments of the present invention, reference Figure 2 and Figure 3 The cell finishing glue sticking device includes a detection component, which is arranged on the bottom plate 100. The detection component is used to detect whether the length of the tape 200 driven by the moving mechanism corresponds to the length required by the cell. Specifically, the detection component includes two second tension wheels 710, an infrared sensor and a sensor sheet 730. The tape 200 passes through the two second tension wheels 710 in sequence, and the two second tension wheels 710 cooperate to provide tension for the tape 200, thereby increasing the friction between the two. One of the second tension wheels 710 is fixedly sleeved with a sensing sheet 730, so that when the adhesive tape 200 moves, the adhesive tape 200 utilizes the friction between the second tension wheel 710 to drive the second tension wheel 710 to rotate, and then drives the sensing sheet 730 to rotate. A plurality of sensing ports are provided on the sensing sheet 730, and the plurality of sensing ports are spaced apart along the circumference of the sensing sheet 730. The infrared sensor is used in conjunction with the sensing sheet 730. When the second tension wheel 710 rotates, the sensing sheet 730 blocks the signal transmitted from the output end of the infrared sensor 720 to the receiving end. When the sensing sheet 730 rotates to the position of the sensing port and the infrared sensor, the receiving end of the infrared sensor receives the signal, thereby utilizing the infrared sensor 720 to sense the number of times the receiving end receives the signal, and in conjunction with the circumference of the second tension wheel 710, the moving length of the adhesive tape 200, that is, the distance moved by the moving mechanism, that is, the distance between the first position and the second position, can be calculated, so that the size of the adhesive tape 200 can be more accurate.

[0052] The implementation principle of the utility model is as follows: when it is necessary to glue the battery cell, the second slide plate 511 slides relative to the second slide rail 421 to drive the contact block 513 to move, so that the distance between the first position and the second position is determined according to the size of the battery cell, that is, the required length of the tape 200 is determined, so that the first cylinder 321 drives the slider 322 to slide relative to the first slide rail 323 to drive the transmission wheel 324 to rise, so that the tape 200 drives the winding wheel 310 to rotate; when the slider 322 moves to the top of the first slide rail 323, there is a large amount of tape 200 cached between the transmission wheel 324 and the first tension wheel 325, at this time, the second cylinder 413 drives the upper pressing block 412 to press the lower pressing block 411 to clamp the tape 200, so that the first synchronous belt 424 is driven to rotate by the first motor 423, thereby driving the screw rod 426 to rotate, and then the screw hole and the screw 426 thread cooperate to make the screw rod 426 rotate. The connecting block moves along the length direction of the screw rod 426, so that the first slide plate 422 slides relative to the second slide rail 421, thereby driving the tape 200 to move to the second position, and then the upper pressure plate is separated from the lower pressure plate to release the tape 200. At this time, the abutting block 513 is driven by the third cylinder 512 to abut against the tape 200, so that the tape 200 abuts against the adsorption roller 520, and then the tape 200 is adsorbed by the negative pressure inside the adsorption roller 520, and then the second motor 531 drives the connecting rod 532 to rotate, thereby driving the fixing frame 533 to rotate along the axial direction of the connecting rod 532, and then the adsorption roller 520 rotates along the axial direction of the connecting rod 532 to drive the tape 200 to the battery cell, and the third motor 534 is used to drive the second synchronous wheel 535 to rotate through the second synchronous belt 536, thereby driving the adsorption roller 520 to rotate to the angle required by the battery cell, so that the tape 200 can adhere to the battery cell. By positioning the abutment block 513 and the adsorption force of the adsorption roller 520 on the tape 200, the relative position of the tape 200 and the adsorption roller 520 is fixed, so that the position where the tape 200 adheres to the battery cell is more precise, reducing the misalignment of the tape 200 when adhering to the battery cell, or even the situation where the tape 200 cannot adhere to the battery cell.

[0053] The above are all preferred embodiments of the present application, and the protection scope of the present application is not limited thereto. Therefore, any equivalent changes made according to the structure, shape, and principle of the present application should be included in the protection scope of the present application.
