Description

Technical Field

[0001] This invention belongs to the technical field of lithium battery manufacturing equipment, and particularly relates to a cell pack insulating sheet device. Background Technology

[0002] A battery cell refers to an electrochemical unit containing positive and negative electrodes. For a specific example of a square aluminum-cased lithium battery, please refer to... Figure 1 The battery cell 20 includes a cuboid battery cell body 21 formed by stacking a cathode plate, an anode plate and a diaphragm, a top cover 22, a cathode tab 231 and an anode tab 232. The cathode tab 231 and the anode tab 232 are flexibly connected between the battery cell body 21 and the top cover 22. The top cover 22 also includes a plastic inner support 221 fixed thereunder for isolating the cathode and anode tabs from the top cover 22. Viewed in an upright position with the top cover facing upwards and the electrolyte inlet facing forward, the cell body 21 includes a right large surface 211, a left large surface (not shown in the figure), a rear side surface 212, a front side surface (not shown in the figure), a top surface 213, and a bottom surface (not shown in the figure). The top cover 22 can move left, right, up, and down relative to the cell body 21. Generally, the bare cell 20 cannot be directly placed into the aluminum casing of the battery. Usually, it is necessary to cover the five exposed surfaces of the cell body 21 with insulating materials to make the cell 20 a tight package so that the electrode plates and separator are not damaged by the casing edge when it is subsequently inserted into the casing. This also ensures that the creepage distance of any point on the insulating material on the surface of the cell 20 to the cell body 21 is ≥4mm, so that the cell 20 has insulation properties to the aluminum casing.

[0003] Please refer to Figure 2 The insulating element 10 is a thin insulating sheet, including a rectangular base plate 13 located in the middle and rectangular first insulating sheet 11 and rectangular second insulating sheet 12 located on both sides of the base plate 13 and bendable relative to the base plate 13 and itself. The first insulating sheet 11 and the second insulating sheet 12 are generally a single unit. The base plate 13, the first insulating sheet 11 and the second insulating sheet 12 are made of polyethylene terephthalate (PET). The base plate 13 is generally 0.1~0.2mm thick, and the first insulating sheet 11 and the second insulating sheet 12 are generally 0.05~0.08mm thick. The base plate 13, the first insulating sheet 11 and the second insulating sheet 12 are fused together to form the insulating element 10.

[0004] The first insulating sheet 11 is also provided with a first longitudinal bending line 111 for bending relative to the base plate 13 at the junction with the base plate 13, and two first transverse bending lines 112 for bending itself, which are perpendicular to the first longitudinal bending line 111 at both ends and are at a distance equal to the length of the battery cell 20. The part outside the two first transverse bending lines 112 is called the first insulating sheet side wing 113. Similarly, the second insulating sheet 12 is provided with a second longitudinal bending line 121 for bending relative to the base plate 13 at the junction with the base plate 13, and two second transverse bending lines 122 for bending itself, which are perpendicular to the second longitudinal bending line 121 at both ends and are at a distance equal to the length of the battery cell 20. The part outside the two second transverse bending lines 122 is called the second insulating sheet side wing 123.

[0005] Lay the insulating component 10 flat, then align the bottom surface of the battery cell 20 (not shown in the figure) with the bottom support plate 13 of the insulating component 10 upright. Flip the first insulating sheet 11 and the second insulating sheet 12 and attach them to the battery cell body 21. Then, weld the first insulating sheet 11 and the second insulating sheet 12 to the plastic inner support 221 of the battery cell top cover 22.

[0006] Folding involves folding the first insulating sheet 11 along the bending line 111 and the second insulating sheet 12 along the second longitudinal bending line 121 onto the left large surface (not shown in the figure) and right large surface 211 of the cell body 21. The cell after folding is as follows: Figure 3 As shown.

[0007] The folding process involves taking two first insulating sheet side wings 113 and two second insulating sheet side wings 123 of the first insulating sheet 11 extending from the left large surface (not shown) and right large surface 211 of the battery cell body 21, which are the rear side surface 211 and front side surface (not shown) of the battery cell body 21, respectively, and folding them along the first transverse bending line 112 and the second transverse bending line 122 onto the rear side surface 211 and front side surface (not shown) of the battery cell body 21, and overlapping them to form an insulating sheet overlap area 14. The folded battery cell is as follows: Figure 4 As shown.

[0008] Therefore, it is necessary to develop an automated device for packaging insulating sheets into battery cells. Summary of the Invention

The flipping driven shaft support is fixed on the flipping support. A flipping plate pad is provided on the front side of the flipping plate facing away from the cell carrier plate. A flipping plate support column is also provided on the back side of the flipping plate facing the cell carrier plate.

[0014] Furthermore, the flipping unit also includes a flipping adjustment slide block and a flipping adjustment locking component. The slide rail of the flipping adjustment slide block and the flipping adjustment locking component are both fixed to the cell carrier plate.

[0016] Furthermore, the folded palm includes multiple folded fingers, and the flap and the flap pad are provided with through grooves through which the multiple folded fingers of the folded palm pass.

[0017] The beneficial effects of this invention are as follows: The battery cell insulation sheet wrapping device of this solution places the battery cell with its top surface facing upwards on the battery cell positioning cavity, and the battery cell holding mechanism presses the battery cell down from the top cover of the battery. A flipping mechanism is located on the left and right sides of the battery cell positioning cavity, and can be flipped to contact the left and right large surfaces of the battery cell. The first insulating sheet of the flipped insulating component is attached to the left large surface of the battery cell body, and the second insulating sheet is attached to the right large surface of the battery cell body.

After flipping, the folding mechanism extends from the edge of the flipping mechanism to fold the side wings of the first insulating sheet to the front and rear sides of the battery cell body, and fold the side wings of the second insulating sheet to the front and rear sides of the battery cell body. The battery cell insulation sheet wrapping device of this invention fixes the folding mechanism to the flipping mechanism, allowing direct folding of the side wings of the insulating sheet to the side of the battery cell after flipping and attaching the insulating sheet to the large surface. This makes operation simple and the insulation sheet wrapping efficiency high. Attached Figure Description
