Background

The lithium battery lamination technology is a lithium battery manufacturing technology which separates positive and negative electrode plates by a lamination device through a diaphragm and sequentially laminates the positive and negative electrode plates into a battery core.

Wherein, the theory of operation of current lithium cell electricity core preparation does: the diaphragm assembly is used for pulling out the diaphragm, the lamination device folds the diaphragm into a Z shape through the reciprocating motion of the lamination table, then the positive and negative pole pieces are alternately placed between the folding diaphragms through the transfer device, in the process of alternately laminating the diaphragm and the positive and negative pole pieces, the diaphragm and the positive and negative pole pieces are repeatedly pulled out or pressed by the thin pressing plate, so that the diaphragm is folded and the positive and negative pole pieces are separated, and the process is repeated for multiple times to finally form the battery cell.

However, the existing lamination device has a complex structure, and only one group of pressure plates are provided, so that the pressure plates can be drawn out only at the two lamination positions of the positive and negative pole pieces, and then the pressure plates are tightly pressed and released to the positive pole piece or the negative pole piece on the diaphragm. In other words, in the whole lamination processing process, the knife drawing action can only be completed at the lamination position, but the knife drawing action takes a certain time, so that the lamination efficiency is low, the productivity is difficult to improve, and the production cost is high.

The first pressure plate 68 and the second pressure plate 69 have a first retracted pressing position and a first extended avoiding position, and when the first pressure plate 68 and the second pressure plate 69 are located at the first retracted pressing position, the first pressure plate 68 and the second pressure plate 69 are relatively retracted and pressed against the material carried by the lamination table 40; when the first and

Of course, the number of the third and

The operation of the lamination device 100 of the present application will be described in detail with reference to the accompanying drawings:

firstly, the translation driving mechanism 20 drives the translation seat 30 to drive the lamination table 40 to move to the second lamination position (of course, it is also possible to select the translation driving mechanism 20 to drive the translation seat 30 to move to the first lamination position to start the operation), the lifting driving mechanism 50 drives the lamination table 40 to vertically move to the required lamination height position, the first pressing mechanism 60 and the second pressing mechanism 70 are both located in an avoiding state, that is, the first pressing plate 68 and the second pressing plate 69 are located at the first unfolding avoiding position, and the third pressing plate 78 and the fourth pressing plate 79 are located at the second unfolding avoiding position. The linear actuator 81 drives the lifting plate 82 to drive the vacancy-filling support plate 83 to move upwards until the vacancy-filling support plate 83 is filled in the corresponding avoiding groove 41, so as to fill the position of the process vacancy of the lamination table 40 and ensure that the whole lamination table 40 is supported.

Then, the first rotating driver 62 drives the first rotating member 641 to rotate, so that the first pressing plate 68 and the second pressing plate 69 move from the first expanded avoiding position to the first collapsed pressing position; meanwhile, the second rotating driver 72 drives the second rotating member 741 to rotate, so that the third pressure plate 78 and the fourth pressure plate 79 move from the second expanded avoiding position to the second retracted pressing position, and the first pressure plate 68 and the second pressure plate 69, and the third pressure plate 78 and the fourth pressure plate 79 are all pressed on the first layer of diaphragm on the lamination table 40.

Then, the negative pole piece is transferred and released on the diaphragm of the first layer by an external transfer device. The second rotating driver 72 drives the second rotating member 741 to rotate, so that the third pressure plate 78 and the fourth pressure plate 79 move from the second retracted pressing position to the second extended avoiding position, and then move to the second retracted pressing position, that is, the third pressure plate 78 and the fourth pressure plate 79 are drawn out and press the negative electrode plate, and the external transfer device retracts.

When the translation driving mechanism 20 drives the translation base 30 to drive the lamination table 40 to the first lamination position, the separator is folded in a Z shape to cover the negative electrode plate received by the lamination table 40 last time, and then the positive electrode plate is released on the separator by the transfer device. The first rotating driver 62 drives the first rotating member 641 to rotate, so that the first pressing plate 68 and the second pressing plate 69 move from the first expanded avoiding position to the first retracted pressing position, that is, the first pressing plate 68 and the second pressing plate 69 press the positive electrode plate, and the external transfer device retracts.

Then, the translation driving mechanism 20 drives the translation seat 30 to drive the lamination table 40 to move from the first lamination position to the second lamination position, and in the process that the lamination table 40 moves from the first lamination position to the second lamination position, the lifting driving mechanism 50 drives the lamination table 40 to descend by a set height (a distance between a negative electrode sheet and a layer of diaphragm), so as to ensure that the height position of the lamination table 40 when receiving a positive electrode sheet is unchanged, and simultaneously the second rotating driver 72 drives the second rotating member 741 to rotate, so that the third pressure plate 78 and the fourth pressure plate 79 move from the second retracted pressing position to the second extended avoiding position, and the third pressure plate 78 and the fourth pressure plate 79 are withdrawn to wait for pressing a next received negative electrode sheet.

When the translation driving mechanism 20 drives the translation base 30 to drive the lamination table 40 to the second lamination position, the separator is folded in a Z shape to cover the positive electrode sheet received by the lamination table 40 last time, and then the negative electrode sheet is released on the separator by the transfer device. The second rotating driver 72 drives the second rotating member 741 to rotate, so that the third pressing plate 78 and the fourth pressing plate 79 move from the second unfolding avoiding position to the second folding pressing position, that is, the third pressing plate 78 and the fourth pressing plate 79 press the negative electrode plate, and the external transfer device retracts.
