Description

Technical Field

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

[0002] The tab is a metal conductor that leads the positive and negative electrodes in the lithium battery cell. It is composed of a film and a metal strip. The film is applied by a coating device used in conjunction with a coating machine, and mainly serves as an insulator. The traditional coating roller uses an open material box. The coating roller is immersed in the slurry, and then the scraper mechanism is used to scrape off the excess slurry on the surface of the coating roller. Finally, the glue is applied to the foil tab through the coating roller.

[0003] For example, Chinese patent CN204307779U discloses a gluing device for lithium-ion battery diaphragms, which forms convex strips extending in the length direction of the gluing roller at intervals on the outer circumference of the gluing roller. When the diaphragm moves, the gluing roller is driven to rotate, and the convex strips adhered with glue in the gluing tank of the gluing roller rotate to the upper end to coat the diaphragm, thereby forming a strip-shaped gluing layer with intervals on the diaphragm, and then the diaphragm is glued at intervals. However, this gluing method is prone to a problem: when the gluing roller is immersed in the glue tank, the slurry on the convex strips is easily thrown off to other positions / equipment of the diaphragm during the rotation of the equipment, causing equipment pollution. Therefore, many coating mechanisms will scrape off the excess slurry on the glue coating roller by adding a scraper structure. However, as in the case of the prior art, even if a scraper is added in front of the convex strip, the two end faces of the convex strip will also be stained with glue, and the glue at the end face position is often difficult to be scraped off by the scraper. Therefore, when the glue roller rotates at a high speed to apply glue, it is also easy to throw off the material, thereby causing pollution to the foil and making it inconvenient for subsequent cleaning.

[0027] refer to Figure 1-6 The utility model provides a lithium battery tab glue coating device, comprising a frame 1, a glue coating roller 2, a glue delivery roller 3, a first driving mechanism 10, a second driving mechanism 11 and a slurry tank 4, wherein both ends of the glue coating roller 2 and the glue delivery roller 3 are connected to the frame 1; during operation, the glue coating roller 2 and the glue delivery roller 3 abut against each other; thereby, the slurry is transferred from the glue delivery roller 3 to the glue coating roller 2, and then the glue coating roller 2 prints the slurry onto the foil tab; the first driving mechanism 10 and the second driving mechanism 11 are both fixed on the frame 1, and the first driving mechanism 10 and the second driving mechanism 11 can respectively drive the glue coating roller 2 and the glue delivery roller 3 to rotate relative to the frame 1; the glue delivery roller 3 is located between the glue coating roller 2 and the slurry tank 4; the slurry tank 4 is arranged along the length direction of the glue delivery roller 3 and is located below the glue delivery roller 3, and at least a part of the glue delivery roller 3 is located in the slurry tank 4.

[0028] refer to Figure 1-6 The specific working process of the lithium battery tab glue coating equipment provided by the utility model is as follows:

[0029] During operation, the glue coating roller 2 and the glue delivery roller 3 are in contact with each other, and the glue delivery roller 3 is partially immersed in the slurry tank 4, and then the first driving mechanism 10 and the second driving mechanism 11 respectively drive the glue coating roller 2 and the glue delivery roller 3 to rotate; during the rotation of the glue delivery roller 3, the slurry is transferred to the glue coating roller 2, and then the glue coating roller 2 prints the slurry on the pole ear. Compared with the traditional method of directly immersing the glue coating disc 21 into the glue tank for gluing, the utility model introduces the glue delivery roller 3 to transfer the slurry, so that the surface of the glue coating roller 2 is not prone to slurry dripping, and when the glue coating roller 2 rotates at a high speed, there will be no material throwing, which can effectively prevent the slurry from contaminating the equipment and causing cleaning difficulties. Therefore, compared with the traditional gluing work, the pole ear gluing equipment provided by the utility model has a better gluing effect, less pollution to the equipment during the gluing process, and is more convenient for later cleaning and maintenance.

[0030] In a further preferred embodiment, a scraper (not shown) is further provided on one side of the glue coating roller 2. The scraper is arranged above the glue transfer roller 3 at intervals, and the scraper is arranged along the length direction of the glue coating roller 2.

During operation, the glue delivery discs 31 transfer the slurry to the glue coating discs 21 for gluing. By setting a plurality of glue coating discs 21, it is possible to achieve gluing of the tabs at intervals without gluing the entire surface; the number of the glue delivery discs 31 corresponds to the glue coating discs 21; in addition, the number of the glue coating discs 21 can also be freely disassembled and set according to the specifications required in the actual process.

[0032] refer to Figure 1 and 6 In this embodiment, the width of the glue delivery disk 31 is smaller than the width of the glue coating disk 21, so that after the glue delivery disk 31 transfers the slurry to the glue coating disk 21, the slurry will not remain on the end surface of the glue coating disk 21, thereby further avoiding the situation of material being thrown off during the rotation of the glue coating roller 2. Figure 6 The disk surface 210 of the glue coating disk 21 refers to the side where the slurry is printed on the foil, and the end surface 211 refers to the two side surfaces of the disk surface; similarly, the disk surface of the glue transfer disk 31 refers to the side where the slurry is transferred to the disk surface of the glue coating disk 21.

The swing mechanism 5 includes a swing arm 50, a swing arm shaft 51 and an adjustment component. The swing arm shaft 51 and the adjustment component are all fixed to the frame 1. The adjustment component can drive the swing arm 50 to swing relative to the swing arm shaft 51; the end of the swing arm 50 away from the swing arm shaft 51 is connected to the glue delivery roller 3, and the adjustment component can drive the glue delivery roller 3 to approach or move away from the glue coating roller 2 through the swing arm 50. The gap between the glue delivery roller 3 and the glue coating roller 2 can be conveniently controlled by adjusting the swing arm 50; when the glue delivery roller 3 needs to be disassembled, the swing arm 50 can be used to control the glue delivery roller 3 to move away from the glue coating roller 2, so that there is enough space for movement between the two rollers. In addition, the swing arm 50 is also provided with a quick-release assembly, that is, the swing arm 50 is provided with a connecting block 501, and the connecting block is hinged to the swing arm 50 (it can also be detachably connected to the swing arm 50), refer to Figure 1 and 2 The glue delivery roller 3 can be quickly removed from the swing arm 50 through the movable connection block 501, which facilitates the removal and installation of the glue delivery roller 3.

In this embodiment, a nut is connected between the screw rod 53 and the first control part 52, that is, the screw rod 53 and the nut are connected by a thread. At this time, the screw rod 53 can be rotated clockwise or counterclockwise by the first control part 52 to make the screw rod 53 move forward and backward (the forward and backward here refers to the movement toward the swing arm 50 as the front, and the movement toward the first control part 52 as the back), and the swing arm 50 is driven to move through the pull rod 55 during the forward and backward movement of the screw rod 53, thereby adjusting the gap between the glue delivery roller 3 and the glue coating roller 2.

The two adjustment blocks 63 are provided with inclined surfaces, and the slurry tank 4 is connected to the adjustment blocks 63 through the fixing member 64. Then, when the two adjustment blocks 63 are close to each other, the slurry tank 4 moves to the high point of the inclined surface, thereby raising the slurry tank 4; and when the two adjustment blocks 63 are away from each other, the slurry tank 4 moves to the low point of the inclined surface, thereby lowering the height of the slurry tank 4; taking the central axis of the fixing member 64 as an example, the end of the two adjustment blocks 63 close to the central axis is the low point of the inclined surface, and the end away from the central axis is the high point of the inclined surface. Similarly, the second control part 61 can also be operated manually, so as to achieve a more accurate fine-tuning effect.
