Description

[0002] During the production process of square aluminum shell battery cells, a layer of insulating film will be coated on the surface of the square aluminum shell battery cells. During the process of coating the insulating film by the film laminating machine, the insulating film skirt located on the side plate of the square aluminum shell battery cells needs to be rolled and folded flat. However, when the existing roller folding device uses the rubber roller to flatten, it will adjust the spacing position of the upper and lower sets of rubber rollers according to the size of the current model of square aluminum shell battery cells. The adjusted rubber rollers are fixedly installed, so the spacing between the upper and lower sets of rubber rollers is fixed. This makes it easy for the skirt to not fit tightly during rolling, causing the skirt to curl up. Therefore, a square aluminum shell battery cell film folding device is designed.

DETAILED DESCRIPTION

[0018] The technical solutions in the embodiments of the utility model will be clearly and completely described below in conjunction with the drawings in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, rather than all of the embodiments; based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the utility model.

[0019] Embodiment 1, by Figure 1-Figure 4 The utility model includes a mounting plate 1, one side of the mounting plate 1 is symmetrically connected to a guide rail 2, the upper and lower sides of the two guide rails 2 are slidably connected to sliders 3, an upper pressure roller frame 4 is connected between the two groups of sliders 3 at the upper part, a lower pressure roller frame 5 is connected between the two groups of sliders 3 at the lower part, the upper pressure roller frame 4 and the lower pressure roller frame 5 are rotatably connected to the upper pressure roller 6 and the lower pressure roller 7 inside, respectively, one side of the upper pressure roller frame 4 is symmetrically connected to an upper fixed rod 8, one side of the lower pressure roller frame 5 is symmetrically connected to a lower fixed rod 9, one end of the upper fixed rod 8 and the lower fixed rod 9 both extend through to one side of the mounting plate 1.

[0020] A support plate 10 is connected to the lower part of one side of the mounting plate 1, and a support plate 11 is symmetrically connected to the upper end of the support plate 10. An upper rotating shaft 12 and a lower rotating shaft 13 are rotatably connected between the two support plates 11. Upper gears 14 are fixedly sleeved on both sides of the outer end of the upper rotating shaft 12, and lower gears 15 are fixedly sleeved on both sides of the outer end of the lower rotating shaft 13. The upper gears 14 and the lower gears 15 on both sides are meshed with each other.

[0021] One end of the upper gears 14 on both sides is connected to an upper connecting plate 16, one end of the two upper connecting plates 16 is connected to an upper U-shaped plate 17, both ends of the inner side of the upper U-shaped plate 17 are rotatably connected to upper connecting rods 18, and the two upper connecting rods 18 are rotatably connected to the two upper fixed rods 8 respectively, and one end of the lower gears 15 on both sides is connected to a lower connecting plate 19, one end of the two lower connecting plates 19 is connected to a lower U-shaped plate 20, and both ends of the inner side of the lower U-shaped plate 20 are rotatably connected to lower connecting rods 21, and the two lower connecting rods 21 are rotatably connected to the two lower fixed rods 9 respectively;

[0022] Springs 22 are connected between the upper connecting plates 16 and the lower connecting plates 19 on both sides, and the inner sides of the upper connecting plates 16 on both sides are connected with transverse plates 23, and the inner sides of the lower connecting plates 19 on both sides are connected with baffles 30. The middle part of the upper end of the transverse plate 23 is threadedly connected with an adjusting screw 24, and the lower end of the adjusting screw 24 abuts against the baffle 30. The upper end of the adjusting screw 24 is connected with a handle 25, and the upper part of the adjusting screw 24 is threadedly sleeved with a locking nut 26;

[0023] By adjusting the position of the screw rod 24 by moving it up and down, the size of the opening between the upper connecting plate 16 and the lower connecting plate 19 can be adjusted, that is, the spacing between the upper pressing roller 6 and the lower pressing roller 7 can be adjusted, so that it can be suitable for the folding of battery cells of different sizes. With the tension of the spring 22, the upper pressing roller 6 and the lower pressing roller 7 can always keep in contact with the upper and lower end surfaces of the battery cell, so that the folding of the battery cell fits tightly; in addition, the meshing between the upper gear 14 and the lower gear 15 makes the upper connecting plate 16 and the lower connecting plate 19 move synchronously when the size of the opening changes, that is, the upper pressing roller 6 and the lower pressing roller 7 move synchronously;

[0024] The support plate 10 is externally connected to a housing 27 , the upper end of the housing 27 is rotatably connected to a cover plate 28 , and one side of the upper end of the cover plate 28 is connected to a handle 29 for conveniently opening the cover plate 28 and rotating and adjusting the adjusting screw 24 .

[0025] Working principle: First, the distance between the upper pressing roller 6 and the lower pressing roller 7 is adjusted according to the size of the battery cell. During the adjustment, the adjusting screw 24 is driven to rotate by rotating the handle 25, thereby causing the adjusting screw 24 to move upward or downward;

[0026] When the adjusting screw 24 moves upward, under the pulling force of the spring 22, the upper connecting plate 16 and the lower connecting plate 19 approach each other, thereby driving the upper pressure roller 6 and the lower pressure roller 7 to approach each other; when the adjusting screw 24 moves downward, the lower end of the adjusting screw 24 can abut against the baffle 30, and as the adjusting screw 24 continues to move downward, the upper connecting plate 16 and the lower connecting plate 19 move away from each other, thereby driving the upper pressure roller 6 and the lower pressure roller 7 to move away from each other, so that the distance between the upper pressure roller 6 and the lower pressure roller 7 can be adjusted;

[0027] In addition, the spacing between the upper pressing roller 6 and the lower pressing roller 7 of the device should preferably be adjusted to be smaller than the size of the battery cell to be processed. In this way, when the battery cell is fed between the upper pressing roller 6 and the lower pressing roller 7, the upper pressing roller 6 and the lower pressing roller 7 are pushed to move in the upper and lower directions by the push of the battery cell. Under the linkage of the upper connecting rod 18 and the lower connecting rod 21, the upper connecting plate 16 drives the upper gear 14, and the lower connecting plate 19 drives the lower gear 15 to mesh with each other, and the formed opening is opened. Due to the action force of the spring 22, the upper connecting plate 16 and the lower connecting plate 19 have a pulling force to approach each other. In this way, the upper pressing roller 6 and the lower pressing roller 7 have a clamping force to approach each other, so that they can fit with the upper and lower end surfaces of the battery cell. Under the extrusion force between the upper pressing roller 6 and the lower pressing roller 7, the contact between the folded edge and the roller is flat, ensuring that the battery cell insulating film is tightly fitted when folding.

[0028] Compared with the traditional method of fixing the distance between the upper and lower pressing rollers, the upper and lower pressing rollers cannot automatically adapt to the size of the battery cell, and thus cannot flatten the folded edge. In this device, the upper pressing roller 6 and the lower pressing roller 7 can approach each other under the tension of the spring 22 when the folded edge is flattened, that is, the upper and lower distances between the upper pressing roller 6 and the lower pressing roller 7 can be adaptively adjusted to adapt to the size of the battery cell, thereby flattening the folded edge of the insulating film on the battery cell.
