Description

Battery core combining and packaging machine

Technical Field

The invention belongs to the technical field of battery production equipment, and particularly relates to a battery core combining and packaging machine.

Background

Referring to fig. 1 to 7, a battery cell 10 refers to an electrochemical cell including a positive electrode and a negative electrode, and in a specific square aluminum-shell lithium battery, the battery cell 10 includes a rectangular parallelepiped battery cell body 11 formed by stacking a negative electrode plate, a positive electrode plate and a separator, and a rectangular parallelepiped top cover 12 with positive and negative electrode posts for external electrical connection, which is flexibly connected through a cathode tab and a positive electrode tab. The bare cell 10 cannot be directly put into the aluminum shell of the battery generally, and the exposed surface of the body of the cell 10 is generally required to be coated with an insulating film 13 and an insulating adhesive, so that the cell 10 becomes a tight package, a pole piece and a diaphragm are not wound and damaged by the shell edge when the cell is subsequently put into the shell, and the creepage distance between any point of the insulating film 13 and the insulating adhesive on the surface of the cell 10 and the cell body 11 is equal to or greater than 4mm, even if the cell 10 has insulating performance on the aluminum shell.

The battery core with the film after the soft connection welding comprises two battery core bodies 11 and a top cover 12, wherein each cathode lug 11a and each anode lug 11b of the two battery core bodies 11 are welded on a cathode column and an anode column of the top cover 12. An insulating film 13 is respectively clamped between one large surface of each of the two cell bodies 11 and the top cover 12, the two cell bodies 11 are separated and spread on two sides of the top cover 12, one large surface of each of the two cell bodies 11 is respectively pressed on one insulating film 13, the two insulating films 13 are retracted to the round angle position of the cell body 11 in the width direction of the cell body 11, the two insulating films 13 are higher than the height of the cell body 11 by about 3mm in the height direction of the cell body 11, the thickness of one cell body 11 is increased by 3mm, and each of the two insulating films 13 is pre-pressed with a transverse through bending line 13a which is easy to bend at the alignment position of the bottom surfaces of the two cell bodies 11. After welding, the two battery cell bodies and the insulating film 13 are turned around the top cover 12 relatively and overlapped by core combination, and the battery cells after core combination are shown in fig. 3. The carrying and core closing requirements of the battery cell 10 with the film are as follows: the relative positions and the bonding relationship of the two cell bodies 11 and the insulating film 13 cannot be changed, and the cathode tab 11a, the anode tab 11b, and the insulating film 13 cannot be twisted and pushed.

After the battery core is combined, packaging operation is needed, wherein the packaging operation comprises film folding, base adhesive sticking, side adhesive sticking and rubber coating.

The folding film is formed by folding the insulating films 13 extending out of the two sides of the battery cell 10 along the bending line 13a to the bottom surface of the battery cell to overlap, and the battery cell after folding is shown in fig. 4.

The insulating film is not provided with glue, and in order to prevent the insulating films on both sides of the bottom surface of the battery cell from loosening, the lap seam 13b of the insulating film needs to be stuck by the base tape strip 14, which is called as base glue sticking, and the battery cell after the base glue sticking is shown in fig. 5.

Since the insulating film is not wrapped on the two sides of the battery cell, after the primer is attached, two side adhesive tapes 15 are attached to the two sides of the battery cell, which is called as side adhesive, and the battery cell after the side adhesive 15 is attached is shown in fig. 6.

After the side glue is attached, two side tape strips 15 extending out of the bottom surface on two large surfaces and two side surfaces of the battery cell are required to be pushed down and lapped on an insulating film on the bottom surface of the battery cell, so that the battery cell is called as a glue coating, and the battery cell after the glue coating is shown in fig. 7.

After encapsulation, the quality of the cell core, the folding film, the base adhesive, the side adhesive and the encapsulation needs to be checked, and appearance detection is needed to be carried out on the packaged cell core, so that the cell core with unqualified appearance of the packaged cell core is removed.

After appearance detection, insulation property of the battery cell package needs to be ensured, and then the insulation resistance value of the packaged battery cell needs to be measured, and the battery cells with unqualified insulation resistance values in the packaged battery cells which are qualified after appearance detection are removed.

In order to realize high-efficiency automatic packaging operation of the battery cells, it is necessary to develop an automatic battery cell combination and packaging machine.
