Description

Technical Field

[0001] The utility model relates to the technical field of lithium batteries, in particular to a glue preparation device and a glue pasting device. Background Art

[0002] In the production and manufacturing process of lithium batteries, it is necessary to perform a glue pasting process on the processed electrode sheets of the battery cells to prevent the cut electrode sheets from generating burrs that pierce the separator and affect the quality of the battery cells. Among them, in order to improve the glue pasting efficiency and the flatness of the glued paper, a glue pasting device is usually used to automatically paste glue on the battery cells.

[0003] However, for the glue pasting devices in the prior art, the length compatibility range of the glued paper is relatively small and cannot be adjusted according to the actual required glue pasting length, resulting in that a glue pasting device can only perform the glue pasting of the electrode sheets of a small number of specifications of lithium batteries, which brings great difficulties to the battery cell type change.

[0004] Therefore, the present application provides a new glue preparation device and a glue pasting device for the above problems. Summary of the Utility Model

[0005] The purpose of the utility model is to provide a glue preparation device to at least alleviate the technical problem that the length compatibility range of the glued paper of the glue pasting device in the prior art is relatively small.

[0006] The purpose of the utility model is also to provide a glue pasting device to further alleviate the technical problem that the length compatibility range of the glued paper of the glue pasting device in the prior art is relatively small.

[0007] Based on the above first purpose, the utility model provides a glue preparation device, which includes a glue preparation mechanism and a glue pressing mechanism;

[0008] The glue preparation mechanism includes a glue preparation roller provided with vacuum adsorption holes and a first rotation driving component capable of driving the glue preparation roller to rotate;

[0009] The glue pressing mechanism includes a glue pressing member, a glue pressing frame rotatably connected to the roller shaft of the glue preparation roller, and a second rotation driving component capable of driving the glue pressing frame to rotate relative to the roller shaft of the glue preparation roller. The glue pressing member is connected to the glue pressing frame and can move towards or away from the roller surface of the glue preparation roller. When the glue pressing member moves towards the roller surface of the glue preparation roller, it can contact the roller surface of the glue preparation roller. When the glue pressing member moves away from the roller surface of the glue preparation roller, there is a gap between the glue pressing member and the roller surface of the glue preparation roller.

[0010] Further, the glue preparation device further includes a glue preparation frame, and the glue preparation roller is rotatably connected to the glue preparation frame;

[0011] The first rotation drive assembly includes a first rotation motor and a first transmission unit. The first rotation motor is installed on the glue preparation rack, and the first rotation motor is drivingly connected to the glue preparation roller through the first transmission unit;

[0012] The second rotation drive assembly includes a second rotation motor and a second transmission unit. The second rotation motor is installed on the glue preparation rack, and the second rotation motor is drivingly connected to the glue pressing rack through the second transmission unit.

[0013] Further, the glue pressing mechanism further includes a glue pressing cylinder. The cylinder barrel of the glue pressing cylinder is installed on the glue pressing rack. The glue pressing member is connected to the piston rod of the glue pressing cylinder. The piston rod expands and contracts relative to the cylinder barrel, and can drive the glue pressing member to move towards or away from the roller surface of the glue preparation roller.

[0014] Adopting the above technical solution, the glue preparation device of the present utility model has at least the following beneficial effects:

[0015] When the glue preparation device is in use, first, the head end of the adhesive tape is set on the roller surface of the glue preparation roller. The second rotation drive assembly drives the glue pressing rack to rotate, so as to drive the glue pressing member to rotate to the head end of the adhesive tape. Then, the glue pressing member moves towards the roller surface of the glue preparation roller to contact the roller surface of the glue preparation roller, so as to press and fix the head end of the adhesive tape between the roller surface of the glue preparation roller and the glue pressing member; thereafter, the first rotation drive assembly drives the glue preparation roller to rotate a certain angle in the first direction, and at the same time, the second rotation drive assembly drives the glue pressing rack to rotate synchronously in the first direction relative to the roller shaft of the glue preparation roller. Thus, on the basis that the head end of the adhesive tape is pressed and fixed between the roller surface of the glue preparation roller and the glue pressing member, the adhesive tape can rotate in the first direction along with the roller surface of the glue preparation roller, so as to pull the adhesive tape a certain length. Cooperating with the vacuum suction holes on the glue preparation roller, the adhesive tape is adsorbed on the roller surface of the glue preparation roller, and the glue preparation of a certain length of the adhesive tape is completed.

[0016] When the length of the adhesive tape to be prepared is relatively long, the adhesive tape can be fed in multiple times according to the length of the prepared adhesive tape. Specifically, after pulling the adhesive tape a certain length in the first direction, the tape preparation roller and the tape pressing frame stop rotating, and the tape pressing member moves away from the roller surface of the tape preparation roller to have a gap with the roller surface of the tape preparation roller. Then, the tape pressing frame is driven to rotate in the second direction by the second rotation driving component to drive the tape pressing member to rotate in the reverse direction to the original position. Then, the tape pressing member moves closer to the roller surface of the tape preparation roller to contact the roller surface of the tape preparation roller, so as to press and fix the middle part of the adhesive tape between the roller surface of the tape preparation roller and the tape pressing member. After that, the first rotation driving component continues to drive the tape preparation roller to rotate a certain angle in the first direction, and at the same time, the second rotation driving component drives the tape pressing frame to rotate synchronously in the first direction relative to the roller shaft of the tape preparation roller. Thus, on the basis that the middle part of the adhesive tape is pressed and fixed between the roller surface of the tape preparation roller and the tape pressing member, the adhesive tape can continue to rotate in the first direction along with the roller surface of the tape preparation roller to pull the adhesive tape a certain length again, and the preparation of the adhesive tape of a certain length is completed for the second time (the second direction is opposite to the first direction).

[0017] Among them, the above steps can be cycled multiple times according to the length of the adhesive tape to be prepared until the adhesive tape is prepared to the required length.

[0018] With such a setting, the tape preparation device can feed the adhesive tape in multiple times according to the length of the adhesive tape to be prepared, realize the preparation of adhesive tapes of any length, greatly improve the compatible range of the tape pasting of the tape pasting device, can be compatible with the tape pasting length requirements of a very large range of clients, reduce the trouble of conversion and modification, improve the compatible ability of the equipment and the product competitiveness, alleviate the technical problem that the compatible range of the length of the adhesive tape pasted by the tape pasting device in the existing technology is relatively small, and reduce the pulling tension of the adhesive tape by feeding the adhesive tape in multiple times, thereby reducing the deformation of the adhesive tape.

[0019] Based on the above second object, the present utility model provides a tape pasting device, which includes a mounting plate and the tape preparation device as described above, and the tape preparation device is arranged on the mounting plate.

[0020] Further, the tape pasting device further includes a unwind reel, a tape opening device for pulling the adhesive tape on the unwind reel, and a tape cutting device for cutting the adhesive tape. The unwind reel, the tape opening device and the tape cutting device are all arranged on the mounting plate;

[0021] The adhesive tape on the unwind reel can reach the tape preparation roller of the tape preparation device after passing through the tape opening device and the tape cutting device in sequence.

[0022] Further, the tape cutting device includes a tape cutting frame and a tape cutting mechanism arranged on the tape cutting frame;

The rubber cutting cylinder is installed on the rubber cutting frame, and the rubber cutting cylinder is drivingly connected to the rubber cutting blade, and can drive the rubber cutting blade to approach or move away from the adhesive tape.

[0024] Further, the rubber cutting device further includes a pressing mechanism disposed on the rubber cutting frame;

[0025] The pressing mechanism includes a first pressing plate, a second pressing plate, and a pressing cylinder installed on the rubber cutting frame. The first pressing plate is disposed on the rubber cutting frame. The pressing cylinder is drivingly connected to the second pressing plate, and the pressing cylinder can drive the second pressing plate to move in a direction approaching or moving away from the first pressing plate. When the second pressing plate moves in a direction approaching the first pressing plate, it can contact the first pressing plate. When the second pressing plate moves in a direction away from the first pressing plate, a gap for the adhesive tape to pass through can be formed between the second pressing plate and the first pressing plate.

[0026] Further, the tape sticking device further includes a translation device capable of driving the adhesive tape preparation device to move in a direction approaching or moving away from the rubber cutting blade.

[0027] Further, the translation device includes a translation motor and a linear module both installed on the mounting plate. The extending direction of the linear module is perpendicular to the moving direction of the rubber cutting blade;

[0028] The translation motor is drivingly connected to the linear module, and the adhesive tape preparation frame of the adhesive tape preparation device is connected to the slider of the linear module.

[0029] Further, the tape opening device includes a tape opening plate disposed on the mounting plate, a tape opening slide rail disposed on the tape opening plate, a tape opening slide seat disposed on the tape opening slide rail, and a tape opening cylinder installed on the tape opening plate and drivingly connected to the tape opening slide seat.

[0034] Wherein, the rubber pasting device further includes a lifting drive assembly installed on the mounting plate and capable of driving the rubber preparation device to move in a direction close to or away from the pole piece.

[0062] Embodiment 1

[0063] Please refer to Figure 7 and Figure 8 As shown in and, this embodiment provides a glue preparation device 1, which includes a glue preparation mechanism and a glue pressing mechanism; the glue preparation mechanism includes a glue preparation roller 11 provided with vacuum adsorption holes and a first rotation driving component 12 capable of driving the rotation of the glue preparation roller 11; the glue pressing mechanism includes a glue pressing member 13, a glue pressing frame 14 rotatably connected to the roller shaft of the glue preparation roller 11, and a second rotation driving component 15 capable of driving the rotation of the glue pressing frame 14 relative to the roller shaft of the glue preparation roller 11. The glue pressing member 13 is connected to the glue pressing frame 14 and can move towards or away from the roller surface of the glue preparation roller 11. When the glue pressing member 13 moves towards the roller surface of the glue preparation roller 11, it can contact the roller surface of the glue preparation roller 11, and when the glue pressing member 13 moves away from the roller surface of the glue preparation roller 11, there will be a gap between it and the roller surface of the glue preparation roller 11.

[0064] It should be noted that this glue preparation device 1 is applied to a gluing device and is used to reserve glue paper for gluing the pole piece for later use.

[0065] When the glue preparation device 1 is in use, first, the leading end of the adhesive tape is set on the roller surface of the glue preparation roller 11. The second rotation driving component 15 drives the glue pressing frame 14 to rotate, so as to drive the glue pressing member 13 to rotate to the leading end of the adhesive tape. Then, the glue pressing member 13 moves towards the roller surface of the glue preparation roller 11 to contact the roller surface of the glue preparation roller 11, thereby pressing and fixing the leading end of the adhesive tape between the roller surface of the glue preparation roller 11 and the glue pressing member 13. After that, the first rotation driving component 12 drives the glue preparation roller 11 to rotate a certain angle in the first direction, and at the same time, the second rotation driving component 15 drives the glue pressing frame 14 to rotate synchronously in the first direction relative to the roller shaft of the glue preparation roller 11. Thus, on the basis that the leading end of the adhesive tape is pressed and fixed between the roller surface of the glue preparation roller 11 and the glue pressing member 13, the adhesive tape can rotate in the first direction along with the roller surface of the glue preparation roller 11 to pull the adhesive tape a certain length, and cooperate with the vacuum suction holes on the glue preparation roller 11 to adsorb the adhesive tape on the roller surface of the glue preparation roller 11, completing the glue preparation of a certain length of the adhesive tape.

[0066] When the length of the adhesive tape to be prepared with glue is relatively long, the adhesive tape can be pressed and fed in multiple times according to the length of the glue preparation. Specifically, after pulling the adhesive tape a certain length in the first direction, the glue preparation roller 11 and the glue pressing frame 14 stop rotating, and the glue pressing member 13 moves away from the roller surface of the glue preparation roller 11 to have a gap with the roller surface of the glue preparation roller 11. Then, the second rotation driving component 15 drives the glue pressing frame 14 to rotate in the second direction to drive the glue pressing member 13 to rotate reversely to the original position. Then, the glue pressing member 13 moves towards the roller surface of the glue preparation roller 11 to contact the roller surface of the glue preparation roller 11, thereby pressing and fixing the middle part of the adhesive tape between the roller surface of the glue preparation roller 11 and the glue pressing member 13. After that, the first rotation driving component 12 continues to drive the glue preparation roller 11 to rotate a certain angle in the first direction, and at the same time, the second rotation driving component 15 drives the glue pressing frame 14 to rotate synchronously in the first direction relative to the roller shaft of the glue preparation roller 11. Thus, on the basis that the middle part of the adhesive tape is pressed and fixed between the roller surface of the glue preparation roller 11 and the glue pressing member 13, the adhesive tape can continue to rotate in the first direction along with the roller surface of the glue preparation roller 11 to pull the adhesive tape a certain length again, and the glue preparation of a certain length of the adhesive tape is completed for the second time (the second direction is opposite to the first direction).

[0067] Among them, the above steps can be cycled multiple times according to the length of the adhesive tape to be prepared with glue until the required length of the adhesive tape is prepared.

[0068] With such a setting, the glue preparation device 1 can press and feed the adhesive tape in multiple times according to the length of the adhesive tape to be prepared with glue, realize the glue preparation of any length, greatly improve the glue pasting compatibility range of the glue pasting device, can be compatible with the glue pasting length requirements of a very large range of clients, reduce the trouble of model change and transformation, improve the compatibility ability of the equipment and the product competitiveness, alleviate the technical problem that the length compatibility range of the adhesive tape pasted by the glue pasting device in the existing technology is relatively small, and by pressing and feeding the adhesive tape in multiple times, reduce the pulling tension of the adhesive tape, thereby reducing the deformation of the adhesive tape.

[0069] Preferably, please refer toFigure 7 and Figure 8 In this embodiment, the glue preparation device 1 further includes a glue preparation rack, and the glue preparation roller 11 is rotatably connected to the glue preparation rack; the first rotation drive assembly 12 includes a first rotation motor and a first transmission unit. The first rotation motor is installed on the glue preparation rack, and the first rotation motor is drivingly connected to the glue preparation roller 11 through the first transmission unit; the second rotation drive assembly 15 includes a second rotation motor and a second transmission unit. The second rotation motor is installed on the glue preparation rack, and the second rotation motor is drivingly connected to the glue pressing rack 14 through the second transmission unit.

[0070] Optionally, the first transmission unit and the second transmission unit may be structures such as chain drive, belt drive, or gear drive.

[0071] Preferably, please refer to Figure 7 and Figure 8 In this embodiment, the glue pressing mechanism further includes a glue pressing cylinder 16. The cylinder barrel of the glue pressing cylinder 16 is installed on the glue pressing rack 14, and the glue pressing member 13 is connected to the piston rod of the glue pressing cylinder 16. The piston rod expands and contracts relative to the cylinder barrel, and can drive the glue pressing member 13 to move closer to or away from the roller surface of the glue preparation roller 11.

[0072] Embodiment Two

[0073] Embodiment Two provides a glue sticking device. The glue sticking device includes the glue preparation device 1 of Embodiment One. The technical features of the glue preparation device 1 disclosed in Embodiment One are also applicable to this embodiment, and the technical features of the glue preparation device 1 already disclosed in Embodiment One will not be described repeatedly. The implementation manner of the glue sticking device will be further described in detail below with reference to the drawings.

[0074] Please refer to Figure 1 The glue sticking device provided in this embodiment includes a mounting plate 2 and the above-mentioned glue preparation device 1, and the glue preparation device 1 is arranged on the mounting plate 2.

[0075] Preferably, the glue sticking device further includes a reel 3, a glue opening device 4 for pulling out the glue paper on the reel 3, and a glue cutting device 5 for cutting the glue paper. The reel 3, the glue opening device 4, and the glue cutting device 5 are all arranged on the mounting plate 2; the glue paper on the reel 3 can reach the glue preparation roller 11 of the glue preparation device 1 after passing through the glue opening device 4 and the glue cutting device 5 in sequence.

[0076] That is, on the mounting plate 2, along the conveying direction of the glue paper, the reel 3, the glue opening device 4, the glue cutting device 5, and the glue preparation device 1 are arranged in sequence.

[0077] With such a setting, in this glue sticking device, after the glue paper roll is placed on the reel 3, the glue opening device 4 pulls out the glue paper on the reel 3 for caching and standby, reducing the pulling tension during glue preparation, alleviating the deformation of the adhesive tape, and the pulled glue paper reaches the glue preparation roller 11 of the glue preparation device 1 after passing through the glue cutting device 5.

[0078] After the leading end of the adhesive tape passes through the tape cutting device 5 and is set on the roller surface of the adhesive tape preparation roller 11, the second rotary drive assembly 15 drives the adhesive tape pressing frame 14 to rotate, so as to drive the adhesive tape pressing member 13 to rotate to the tape cutting device 5. Then, the adhesive tape pressing member 13 moves towards the roller surface of the adhesive tape preparation roller 11 to contact the roller surface of the adhesive tape preparation roller 11, so as to press and fix the leading end of the adhesive tape between the roller surface of the adhesive tape preparation roller 11 and the adhesive tape pressing member 13. After that, the first rotary drive assembly 12 drives the adhesive tape preparation roller 11 to rotate a certain angle in the first direction, and at the same time, the second rotary drive assembly 15 drives the adhesive tape pressing frame 14 to rotate synchronously in the first direction relative to the roller shaft of the adhesive tape preparation roller 11, so that the adhesive tape rotates in the first direction along with the roller surface of the adhesive tape preparation roller 11, so as to pull the adhesive tape by a certain length, and the preparation of the adhesive tape with a certain length is completed.

[0079] When the length of the adhesive tape to be prepared is relatively long, the adhesive tape can be pressed and fed in multiple times according to the preparation length until the adhesive tape with the required length is prepared. Specifically, after pulling the adhesive tape by a certain length in the first direction, the adhesive tape preparation roller 11 and the adhesive tape pressing frame 14 stop rotating, and the adhesive tape pressing member 13 moves away from the roller surface of the adhesive tape preparation roller 11 to have a gap with the roller surface of the adhesive tape preparation roller 11. Then, the second rotary drive assembly 15 drives the adhesive tape pressing frame 14 to rotate in the second direction, so as to drive the adhesive tape pressing member 13 to rotate reversely to the tape cutting device 5. Then, the adhesive tape pressing member 13 moves towards the roller surface of the adhesive tape preparation roller 11 to contact the roller surface of the adhesive tape preparation roller 11, so as to press and fix the middle part of the adhesive tape between the roller surface of the adhesive tape preparation roller 11 and the adhesive tape pressing member 13. After that, the first rotary drive assembly 12 continues to drive the adhesive tape preparation roller 11 to rotate a certain angle in the first direction, and at the same time, the second rotary drive assembly 15 drives the adhesive tape pressing frame 14 to rotate synchronously in the first direction relative to the roller shaft of the adhesive tape preparation roller 11, so that on the basis that the middle part of the adhesive tape is pressed and fixed between the roller surface of the adhesive tape preparation roller 11 and the adhesive tape pressing member 13, the adhesive tape can continue to rotate in the first direction along with the roller surface of the adhesive tape preparation roller 11, so as to pull the adhesive tape by a certain length again, and the preparation of the adhesive tape with a certain length is completed for the second time. Among them, the above steps can be cycled multiple times according to the length of the adhesive tape to be prepared until the adhesive tape with the required length is prepared.

[0080] At this time, the trailing end of the adhesive tape is located at the tape cutting device 5, and the trailing end of the adhesive tape can be cut off by the tape cutting device 5, and the preparation of the adhesive tape with the required length is completed.

[0081] In summary, the adhesive tape pasting device can realize the preparation of adhesive tapes with any length, greatly improving the pasting compatibility range of the pasting device, and further alleviating the technical problem of the relatively small length compatibility range of the adhesive tapes pasted by the pasting device in the prior art.

[0082] Preferably, please refer to Figure 4 and Figure 5, in this embodiment, the rubber cutting device 5 includes a rubber cutting frame 51, and a pressing and fixing mechanism and a rubber cutting mechanism both arranged on the rubber cutting frame 51; the pressing and fixing mechanism includes a first pressing plate 52, a second pressing plate 54, and a pressing cylinder 53 installed on the rubber cutting frame 51. The first pressing plate 52 is arranged on the rubber cutting frame 51, the pressing cylinder 53 is drivingly connected to the second pressing plate 54, and the pressing cylinder 53 can drive the second pressing plate 54 to move in a direction close to or away from the first pressing plate 52. When the second pressing plate 54 moves in a direction close to the first pressing plate 52, it can contact the first pressing plate 52, and when the second pressing plate 54 moves in a direction away from the first pressing plate 52, a gap for the adhesive tape to pass through can be formed between the second pressing plate 54 and the first pressing plate 52; the rubber cutting mechanism includes a rubber cutting cylinder 55 and a rubber cutting blade 56. The rubber cutting cylinder 55 is installed on the rubber cutting frame 51, and the rubber cutting cylinder 55 is drivingly connected to the rubber cutting blade 56 and can drive the rubber cutting blade 56 to approach or move away from the adhesive tape.

[0083] With such a setting, after the adhesive tape roll is placed on the unwinding disc 3, the unwinding device 4 pulls the adhesive tape on the unwinding disc 3, and the pulled adhesive tape passes through the gap between the first pressing plate 52 and the second pressing plate 54 in the rubber cutting device 5 and then reaches the glue preparation roller 11 of the glue preparation device 1.

[0084] Among them, when the adhesive tape is conveyed along with the rotation of the glue preparation roller 11, there is a gap between the first pressing plate 52 and the second pressing plate 54 to facilitate the conveyance of the adhesive tape; when the adhesive tape needs to be cut, first, the pressing cylinder 53 drives the second pressing plate 54 to move in a direction close to the first pressing plate 52 so that the second pressing plate 54 contacts the first pressing plate 52, thereby pressing the adhesive tape between the second pressing plate 54 and the first pressing plate 52 to facilitate the cutting of the adhesive tape. Then, the rubber cutting cylinder 55 drives the rubber cutting blade 56 to approach the adhesive tape to cut the adhesive tape.

[0085] Preferably, please refer to Figure 6 , in this embodiment, the pasting device further includes a translation device 6 capable of driving the glue preparation device 1 to move in a direction close to or away from the rubber cutting blade 56.

[0086] With such a setting, before the rubber cutting blade 56 cuts the adhesive tape, first, the translation device 6 drives the glue preparation device 1 to move in a direction away from the rubber cutting blade 56 so that there is a certain distance between the glue preparation device 1 and the rubber cutting blade 56, preventing damage to the glue preparation roller 11 when the rubber cutting blade 56 cuts the adhesive tape.

[0087] Preferably, please refer to Figure 7 and Figure 9 , in this embodiment, the translation device 6 includes a translation motor 61 and a linear module 62 both installed on the mounting plate 2. The extending direction of the linear module 62 is perpendicular to the moving direction of the rubber cutting blade 56; the translation motor 61 is drivingly connected to the linear module 62, and the glue preparation frame of the glue preparation device 1 is connected to the slider of the linear module 62.

[0088] With such a setting, the translation motor 61 drives the linear module 62 to move, causing the glue preparation rack of the glue preparation device 1 to slide along the extension direction of the linear module 62. As a result, the glue preparation roller 11 moves relative to the cutting blade 56 in a direction perpendicular to the moving direction of the cutting blade 56. Please refer to Figure 10 , so that in the vertical direction, there is a gap between the highest point of the glue preparation roller 11 and the cutting blade 56, with a lateral gap a, to prevent the cutting blade 56 from damaging the glue preparation roller 11 when cutting the adhesive tape.

[0089] Preferably, please refer to Figure 3 , in this embodiment, the glue opening device 4 includes a glue opening plate 41 provided on the mounting plate 2, a glue opening slide rail 42 provided on the glue opening plate 41, a glue opening slide seat 43 provided on the glue opening slide rail 42, and a glue opening cylinder 44 mounted on the glue opening plate 41 and drivingly connected to the glue opening slide seat 43. A glue opening moving roller 45 is provided on the glue opening slide seat 43, and a plurality of glue opening fixed rollers 46 are provided on the glue opening plate 41. The plurality of glue opening fixed rollers 46 are distributed on both sides of the glue opening slide rail 42. The glue opening cylinder 44 can drive the glue opening slide seat 43 to slide along the glue opening slide rail 42 to drive the glue opening moving roller 45 to slide relative to the glue opening fixed rollers 46, achieving the purpose of opening the adhesive tape on the unwinding reel 3.

[0090] Preferably, please refer to Figure 1 and Figure 2 , in this embodiment, the tape sticking device further includes a clamping device and a shearing device 7 capable of cutting the pole piece; the clamping device includes a first clamping mechanism 81 and a second clamping mechanism 82 both capable of clamping the pole piece. The shearing device 7 is arranged between the first clamping mechanism 81 and the second clamping mechanism 82, and the first clamping mechanism 81 can move in a direction close to or away from the second clamping mechanism 82; after the pole piece is clamped between the first clamping mechanism 81 and the second clamping mechanism 82, the pole piece is parallel to the tangent of the roller surface of the glue preparation roller 11; wherein, the tape sticking device further includes a lifting drive assembly 9 mounted on the mounting plate 2 and capable of driving the glue preparation device 1 to move in a direction close to or away from the pole piece.

[0091] With such a setting, after the pole piece is transferred to the tape sticking device, the pole piece is held by the first clamping mechanism 81 and the second clamping mechanism 82. At this time, the first clamping mechanism 81 clamps the position of the pole piece close to the front end, and the second clamping mechanism 82 clamps the position of the pole piece close to the rear end. The pole piece is cut by the shearing device 7. At this time, the pole piece is cut into two sections, one section is clamped by the first clamping mechanism 81, and the other section is clamped by the second clamping mechanism 82. It should be noted that burrs will be generated after the pole piece is cut, and the burrs are likely to pierce the diaphragm and affect the quality of the battery cell. Therefore, the two cut sections of the pole piece need to be separated by a certain distance and connected with an adhesive tape. Therefore, the tape sticking device in this embodiment drives one section of the pole piece to move away from the second clamping mechanism 82 through the first clamping mechanism 81, so that the two sections of the pole piece are separated by a certain distance.

[0092] At this time, the first rotation drive assembly 12 drives the glue preparation roller 11 to rotate, so that the adhesive tape on the glue preparation roller 11 rotates to a position corresponding to the pole piece. Then, the lifting drive assembly 9 drives the glue preparation device 1 to move towards the pole piece, so that the glue preparation roller 11 contacts the pole piece. Thus, the adhesive tape on the glue preparation roller 11 adheres to the pole piece. And during the transmission of the pole piece, the first rotation drive assembly 12 drives the glue preparation roller 11 to rotate, so that the rotation direction of the glue preparation roller 11 is the same as the transmission direction of the pole piece, and the rotation linear velocity of the glue preparation roller 11 is the same as the transmission of the pole piece. Thus, the adhesive tape is quickly pasted onto the pole piece.

[0093] Among them, the movement of the glue preparation device 1 towards or away from the pole piece is independently controlled by the lifting drive assembly 9, which can conveniently adjust the position of pasting glue and the force during pasting glue arbitrarily. The pasting position is accurate, and the number of bubbles during pasting glue is small, greatly improving the pasting effect and enhancing the quality of the battery cell. In addition, during the transmission of the pole piece, the glue preparation roller 11 is driven to rotate actively by the first rotation drive assembly 12, which can realize the high-speed chasing pasting function, improve the pasting efficiency, and well solve the defects in the prior art such as poor quality of pasting glue on the pole piece, easy stretching and deformation of the pole piece, and affecting the battery quality.

[0094] Optionally, the lifting drive assembly 9 is a lifting drive cylinder or a lifting drive module, etc. Its specific structure is not limited here as long as it can realize driving the glue preparation device 1 to move linearly.

[0095] Preferably, please refer to Figure 1 , in this embodiment, the unwinding reel 3, the glue opening device 4, the glue cutting device 5 and the glue preparation device 1 together form a pasting unit. The pasting equipment includes two pasting units, and the two pasting units are symmetrically arranged on both sides of the pole piece.

[0096] Such a setting realizes the pasting of the adhesive tape on the pole piece in opposite directions, making the number of bubbles during pasting glue less and the pasting effect more ideal.

[0097] The pasting equipment of this embodiment has the advantages of the glue preparation device 1 in Embodiment 1. These advantages have been described in detail in Embodiment 1 and will not be repeated here.

[0098] Finally, it should be noted that: the above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit it; although the present invention has been described in detail with reference to the foregoing embodiments, those of ordinary skill in the art should understand that: they can still modify the technical solutions described in the foregoing embodiments, or perform equivalent replacements on some or all of the technical features; and these modifications or replacements do not make the essence of the corresponding technical solutions deviate from the scope of the technical solutions of the various embodiments of the present invention.
