The modular pole piece cutting device 100 further comprises a pole tab guiding assembly 8, the pole tab guiding assembly 8 is mounted on the mounting base 1, the pole tab guiding assembly 8 is located at one end of the pole piece guiding assembly 7, the pole tab guiding assembly 8 comprises a first guiding piece 81 and a second guiding piece 82, the first guiding piece 81 is mounted on the connecting plate 13, the second guiding piece 82 is mounted on the supporting plate 122, a pole tab channel 80 is formed between the first guiding piece 81 and the second guiding piece 82, and the inlet width of the pole tab channel 80 is larger than the outlet width of the pole tab channel 80. The tab guide assembly 8 is used to guide the tabs on the pole pieces during the tape-moving process of the pole pieces, so as to prevent the tabs from being folded when passing through the modular pole piece cutting device 100.
Preferably, the modular pole piece cutting device 100 further comprises a second driving unit, the second driving unit comprises a connecting seat, a sliding seat and a driving mechanism, the connecting seat is provided with a guide rail, the sliding seat is slidably connected with the guide rail, the mounting seat 1 is fixedly mounted on the sliding seat, and the driving mechanism drives the sliding seat to slide along the guide rail. Through setting up the second drive unit for modularization pole piece cutting device 100 can link with the coiling head of electricity core winder, and cooperate the coiling head of electricity core winder to carry out the book system of electric core.
The following describes the cutting process of the modular pole piece cutting apparatus 100:
when modularization pole piece cutting device 100 is in non-cutting state (initial state), the body of rod of cylinder is in the withdrawal state, and at this moment, cutter holder 2 is in the lifting state, and second cutter 4 is kept away from to first cutter 3. Meanwhile, the limit plate 62 of the pressing unit 6 is adjacent to the second connection block 22 of the cutter holder 2, so that the second connection block 22 drives the pressing plate 63 to be lifted together through the limit plate 62 and the second guide post 61, the pressing plate 63 is far away from the support plate 122, and the first spring 64 is compressed.
When modular pole piece cutting apparatus 100 is in a non-cutting state, a pole piece enters modular pole piece cutting apparatus 100 from pole piece passage 70 of pole piece guide assembly 7 and passes out of modular pole piece cutting apparatus 100 between pressure plate 63 and support plate 122.
When the pole piece is required to be cut, the rod body of the air cylinder extends out, and the cutter base 2 is driven to move downwards, so that the first cutter 3 on the cutter base 2 moves towards the second cutter 4, and the pole piece is cut. While the first cutter 3 moves toward the second cutter 4, the pressing plate 63 moves toward the supporting plate 122 by the elastic force of the first spring 64 as the cutter holder 2 moves downward. Since the moving distance of the pressing plate 63 moving to the supporting plate 122 is less than the moving distance of the cutting edge of the first cutting knife 3 moving to the cutting edge of the second cutting knife 4, the pressing plate 63 will move to the supporting plate 122 first under the elastic force of the first spring 64, and press the pole piece in cooperation with the supporting plate 122 under the elastic force of the first spring 64. At this time, the cutting edge of the first cutter 3 does not reach the cutting edge of the second cutter 4, so the cylinder continues to drive the cutter holder 2 to move downwards until the cutting edge of the first cutter 3 is matched with the cutting edge 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. And in the process that the first cutter 3 moves back to the second cutter 4, the cutting edge of the first cutter 3 is firstly separated from being matched with the cutting edge of the second cutter 4, and at the moment, the pole piece is still pressed by the pressing plate 63 and the supporting plate 122. With the continuous lifting of the cutter holder 2, the second connecting block 22 of the cutter holder 2 contacts the limiting plate 62 of the pressing unit 6, so that the pressing plate 63 is driven by the second guide post 61 to be lifted together, the pressing plate 63 is far away from the supporting plate 122, the pressing of the pole piece is released, and the first spring 64 is compressed. When the cylinder reset is complete, the modular pole piece cutting apparatus 100 is in an initial state.
It can be seen that above-mentioned structural design for compress tightly between unit 6 and the cutter holder 2 can enough carry out the linkage, again can the mutual independent motion, thereby effectively prevent to compress tightly the in-process at the pole piece and excessively extrude the pole piece, avoid the pole piece impaired, guaranteed the quality of the electric core of coiling.
