While the pressing plate 63 moves toward the support plate 122 under the elastic force of the first spring 64 as the cutter holder 2 moves downward during the movement of the first cutter 3 toward the second cutter 4. Since the moving distance of the pressing plate 63 to the supporting plate 122 is smaller than the moving distance of the cutting edge of the first cutter 3 to the cutting edge of the second cutter 4, the pressing plate 63 will move to the supporting plate 122 under the action of the elastic force of the first spring 64, and the pressing plate is pressed by the supporting plate 122 under the action of the elastic force of the first spring 64. At this time, the blade of the first cutter 3 has not reached the blade of the second cutter 4, and therefore, the cylinder continues to drive the cutter seat 2 to move downward until the blade of the first cutter 3 cooperates with the blade of the second cutter 4 to cut off the pole piece.
When the pole piece is cut off, the cylinder retracts and resets and drives the cutter holder 2 to lift, so that the first cutter 3 on the cutter holder 2 moves back to the second cutter 4. During the movement of the first cutter 3 away from the second cutter 4, the cutting edge of the first cutter 3 is disengaged from the cutting edge of the second cutter 4, and at this time, the pole piece is still pressed by the pressing plate 63 and the supporting plate 122. Along with the continuous lifting of the cutter holder 2, the second connecting block 22 of the cutter holder 2 is contacted with the limiting plate 62 of the compressing unit 6, so that the pressing plate 63 is driven to be lifted together by the second guide post 61, the pressing plate 63 is far away from the supporting plate 122, the compression of the pole piece is relieved, and the first spring 64 is compressed. When the cylinder reset is completed, the modular pole piece cutting device 100 is in an initial state.
Therefore, the above structural design can realize linkage and mutual independent movement between the pressing unit 6 and the cutter seat 2, so that excessive pole piece extrusion in the pole piece pressing process is effectively prevented, the pole piece is prevented from being damaged, and the quality of the wound battery cell is ensured.
Square power cell winder:
The square power battery cell winding machine comprises the modularized pole piece cutting device in the modularized pole piece cutting device embodiment, so that the cutting quality of the pole piece can be effectively improved, the pole piece is prevented from moving in the cutting process, excessive burrs and overlarge edges of the cut pole piece are avoided, in addition, the damage of the pole piece caused by excessive extrusion can be avoided, and the quality of the wound battery cell is ensured.
Finally, it should be emphasized that the foregoing description is merely illustrative of the preferred embodiments of the invention, and that various changes and modifications can be made by those skilled in the art without departing from the spirit and principles of the invention, and any such modifications, equivalents, improvements, etc. are intended to be included within the scope of the invention.
