Description

Technical Field

[0001] The invention belongs to the technical field of battery production equipment, and in particular relates to a battery core packaging machine. Background Art

[0002] Please see Figures 1 to 4 , the battery cell 10 refers to an electrochemical unit containing positive and negative electrodes. In a specific square aluminum shell lithium battery, the battery cell 10 includes a rectangular battery cell body 11 formed by stacking cathode and anode electrode sheets and a diaphragm, and a rectangular top cover 12 with positive and negative poles for external electrical connection flexibly connected through cathode ears and anode ears. Generally, the bare battery cell 10 cannot be directly placed into the aluminum shell of the battery. Usually, it is necessary to coat the exposed surface of the battery cell 10 body with an insulating film 13 and insulating glue to make the battery cell 10 a tight package so that the electrode sheets and diaphragms are not damaged by the shell edge when they are subsequently placed in the shell, and the creepage distance of any point on the insulating film 13 and insulating glue on the surface of the battery cell 10 to the battery cell body 11 is ≧4mm, that is, the battery cell 10 has insulating properties to the aluminum shell.

[0003] The cell assembling process is to relatively flip and overlap the two cell bodies 11 of the incoming cell 10 together with the two insulating films 13 around the top cover 12 .

[0004] After the battery cells are assembled, they need to be packaged, which includes film folding, bottom glue sticking, side glue sticking and glue wrapping.

[0005] The folding film is to fold the insulating film 13 extending from the bottom surface of the two large surfaces of the battery cell 10 along the bending line 13a to the bottom surface of the battery cell and overlap them. Figure 1 shown.

[0006] The insulating film is not prepared with glue. In order to prevent the insulating film on both sides of the bottom surface of the battery cell from loosening, it is necessary to use a bottom glue strip 14 to stick the overlap 13b of the insulating film, which is called bottom glue. Figure 2 shown.

[0007] Since the insulating film does not wrap around the two sides of the battery cell, after the bottom glue is applied, two side adhesive tape strips 15 need to be applied on the two sides of the battery cell, which is called side adhesive. Figure 3 shown.

[0008] After the side glue is applied, the two side glue strips 15 extending from the bottom surface on the two large surfaces and two side surfaces of the battery cell need to be pushed down and overlapped on the insulating film on the bottom surface of the battery cell, which is called glue encapsulation. Figure 4 shown.

[0009] In order to realize efficient automated packaging of battery cells, it is necessary to develop an automated battery cell packaging machine. Summary of the invention

[0015] The transfer device is located between the film folding and transferring device and the flipping and transferring device, and is used to transfer the battery cell from the film folding and transferring device to the flipping and transferring device;

[0016] The flipping and transferring device is used to transfer the battery cell after the bottom glue is applied to the side glue application device, and at the same time flip the battery cell from a vertical posture to a horizontal posture. The flipping and transferring device has a flippable side glue application fixture for clamping the battery cell;

[0017] The side glue sticking holding device is used to hold the bottom surface of the battery cell before and during the side glue sticking process, and assist the side glue sticking fixture in clamping and positioning the battery cell;

[0018] The side adhesive sticking device is used to stick the two side adhesive tape strips to the two side surfaces of the battery cell respectively, and fold and stick them to the insulating films on the two large surfaces of the battery cell at the same time;

[0019] The side glue-to-encapsulation transfer device spans the flipping and transferring device and the encapsulation transfer device, and is used to transfer the battery cell after side glue-on to the encapsulation transfer device;

[0020] The glue coating transfer device is used to transfer the battery cell after side glue is attached to a position close to the glue coating device, and the glue coating transfer device is provided with a glue coating clamp for clamping the battery cell;
