Description

Sheet feeding guide device for wide-width pole piece

Technical Field

The utility model belongs to the technical field of lithium cell production technique and specifically relates to a piece guider goes into of broad width pole piece is related to.

Background

With the wider application of power batteries, the innovation of the power batteries also presents the trend of multi-dimensional development, and the capacity of a single battery in partial fields has higher requirements. Increasing the size of the cell is certainly the simplest and fastest way to increase capacity. Wherein increasing the height of the cell means that the width of the cell's pole pieces increases.

Compared with the common pole piece, the wide pole piece is more easily folded in the winding preparation process of the battery. Particularly, the pole piece of the existing winding equipment is easy to be damaged by curling, bending and the like due to self weight in the suspension process of the pole piece entering the winding needle. In view of the above, there is a need to provide a guiding device for guiding a wide pole piece.

SUMMERY OF THE UTILITY MODEL

The utility model discloses a solve above-mentioned problem and provide a piece guider goes into of broad width pole piece, including cylinder, connecting block and the board of blowing, the connecting block with the board of blowing is connected, the cylinder drive the connecting block removes, drives the board of blowing rotates, it is equipped with the gas hole on the board to blow, the gas hole is located the one end of board of blowing, gas hole and air pump intercommunication.

As a preferable technical scheme, the end part of the air blowing plate is provided with an inclined plane, and the air blowing holes are uniformly arranged on the inclined plane and the outer surface close to the inclined plane.

As a preferable technical solution, the blowing device is further provided with a rotating shaft, and the blowing plate rotates with the rotating shaft as an axis.

As a preferred technical scheme, a rotating block is arranged on the air blowing plate, the rotating block is arranged at one end, far away from the air blowing hole, of the air blowing plate, the rotating shaft is arranged on the rotating block, and the connecting block is connected with the rotating block.

The beneficial effects of the utility model reside in that: above-mentioned income piece guider of broad width pole piece blows the pole piece before rolling up the pole piece, makes the pole piece receive the thrust of its direction of motion of a perpendicular to, avoids taking place to curl owing to the dead weight of pole piece, buckle the scheduling problem and destroy the pole piece, can combine two kinds of devices of direction and blowing to a device simultaneously for the structure of equipment is compacter, and the volume of equipment reduces, reduces the area of equipment, and enables the production time and reduces.

fig. 2 is a schematic working diagram of the sheet-feeding guide device for wide-width pole pieces according to the present invention.

Detailed Description

The invention will be further elucidated with reference to the accompanying drawings:

please refer to fig. 1 and fig. 2, a sheet feeding guide device for a wide-width pole piece, which includes a rotating shaft 4, a cylinder 3, a connecting block 2 and a blowing plate 1, wherein the connecting block 2 is connected to the blowing plate 1, the rotating shaft 4 is disposed in the blowing plate 1, the cylinder 3 drives the connecting block 2 to move, so as to drive the blowing plate 1 to rotate around the rotating shaft 4, the blowing plate 1 is provided with a blowing hole 11, an inclined plane 12 is disposed at an end of the blowing plate 11, the blowing hole 11 is uniformly disposed on the inclined plane 12 and on an outer surface close to the inclined plane 12, the blowing hole 11 is communicated with an air pump, so that the blowing plate 1 can blow out stable air pressure when rotating at different angles, so that the pole piece a is subjected to stable thrust perpendicular to a moving direction of the pole piece a, and the pole piece a is prevented from being bent.

Referring to fig. 2, the air blowing plate 1 is provided with a rotating block 13, the rotating block 13 is disposed at one end of the air blowing plate 1 far from the air blowing hole 11, the rotating shaft 4 is disposed on the rotating block 13, the connecting block 2 is connected to the rotating block 13, and the air cylinder 3 is driven to push the rotating block 13 to rotate around the rotating shaft 4 through the connecting block 2, so as to drive one end of the air blowing plate 1, where the air blowing hole 11 is disposed, to approach the pole piece a. Meanwhile, the angle of the blowing plate 1 can be adjusted according to the actual angle required by the pole piece a to be fed into the winding shaft b, and the angle can be obtained by adjusting the holding angle between the rotating shaft 4 and the connecting block 2 or adjusting the relative angle between the blowing block 1 and the rotating shaft 4.

When the winding shaft b drives the pole piece a to be wound to form the battery core, the pole piece a needs to be stably conveyed to the winding shaft b, the air cylinder 3 is driven to drive the blowing plate 1 to rotate in the state, the end part of the blowing plate 1, which is provided with the blowing hole 11, moves towards the pole piece a, the end part is overlapped with a path of the pole piece a for sheet feeding, the blowing hole 11 is connected with the air pump, the blowing hole 11 continuously outputs airflow to provide thrust for the pole piece a when the pole piece a is suspended, the pole piece 5 bends outwards under the action of the thrust, the pole piece a is prevented from sagging or curling inwards due to dead weight, and the pole piece a is ensured to be wound by the winding shaft b according to a set route. When the winding shaft b is not wound, the air cylinder 3 is reset, so that the air blowing plate 1 is retracted, and the interference with the work of other mechanisms is prevented.
