Description

Technical Field

[0001] The present invention relates to the field of lithium battery production, and in particular to a lithium battery packaging production line. Background Art

[0002] Lithium battery is a rechargeable battery that uses lithium ions as charge carriers. During discharge, lithium ions move from the negative electrode to the positive electrode, and vice versa during charging. Lithium batteries have the advantages of high energy density, long cycle life and low self-discharge rate, so they are widely used in portable electronic devices, electric vehicles, energy storage systems and other fields. Cylindrical lithium batteries are the most common. The existing cylindrical lithium battery production line production process includes slurry preparation, coating, drying, winding / stacking, battery cell assembly, liquid injection, formation, packaging, etc. The produced lithium batteries are finally packaged and shipped. The existing lithium battery packaging line will test the battery before packaging. The testing process is not only inefficient, but also requires a lot of manpower. Secondly, users often require different voltages according to their needs. The traditional method is to manually group the batteries after a single battery film is applied. The purpose of the grouping is to combine multiple batteries together and then weld the pins.

[0036] Resistance detection principle:

[0037] First, the controller 16 is used to start the control moving motor 317, and the moving motor 317 controls the gear 315 on the fixed plate 311 to rotate. During the rotation of the gear 315, the rack 314 is driven to move. At this time, the moving seat 312 drives the detection mechanism 32 to the upper part of the battery. At this time, the detection mechanism 32 obtains the detection instruction through the controller 16 and starts the detection.

[0040] Grouping principle:

[0041] After the detection mechanism 32 completes the detection, the batteries with different internal resistances are placed on the second conveyor line 4 respectively. During the conveying process of the second conveyor line 4, when the battery is in the corresponding grouping slot 504, the grouping electric cylinder 501 corresponding to the grouping slot 504 is started, and the battery is pushed into the grouping slot 504 by the push plate 502, so that the different internal resistance classification is realized. In order to facilitate the subsequent battery film coating, the horizontally placed battery needs to be changed to a vertical placement. The principle method of adjustment is: the controller 16 controls the sliding cylinder 508 inside the protective shell 506 to start, and the sliding cylinder 508 drives the slider 507 to move as a whole. When the whole moves, the telescopic rod 512 drives the receiving plate 5 13 reaches the end of the battery grouping slot 504 to be received.

[0048] Arrangement process:

[0049] After the first glue spraying is completed, the self-propelled device 1140 moves to the designated area according to the operation requirements, and then, under the action of the second lifting electric cylinder 1144 and the second telescopic electric cylinder 1145, the battery is first passed through the clamping column of the finger cylinder 1149, and then the flip motor 1147 is started, so that the finger cylinder 1149 turns the positive and negative poles of the specified battery, and then places it on the upper part of the adjacent battery after the turn, so that the batteries to be contacted are exactly one positive and one negative, and the positive and the negative are the ends of the battery, which is convenient for subsequent welding of the pins, and after the turn, it is placed on the upper part of the adjacent battery. , so that the batteries that are in contact with each other are exactly one positive and one negative. Taking two layers and two columns as an example, the upper and lower layers are composed of two batteries, and one end of each layer is the positive and negative electrodes of the two batteries in the layer. The main purpose of the rotating mechanism 114 is to adjust the order and number of grouping according to needs. After the grouping is completed, it is necessary to spray glue between the two layers so that the two layers will stick together. This step is mainly carried out by spraying glue through the clamping part of the finger cylinder 1149, which is equivalent to secondary glue spraying. After completion, it is clamped and transported to the sixth conveyor line 12 by the finger cylinder 1149 for welding pins. The specific number of layers and columns of the grouping can be set according to actual conditions.

[0050] The fifth conveying plate 10 is tilted to ensure that the positive poles of the batteries falling into the grouping cavity 110 are all located on one side, which will not cause confusion during the grouping process. An intermittent electric cylinder 19 is also provided at one end of the fifth conveying plate 10. A slide plate 20 is fixed at the output end of the intermittent electric cylinder 19, and the slide plate 20 is in contact with the fifth conveying plate 10.
