The composite pole piece cutting machine comprises a composite device 810, a relay device 820 and a cutting device 830, wherein the composite device 810 is used for compounding pole pieces and a diaphragm to form a material belt 900, the relay device 820 is located at the downstream of a conveying path of the composite device 810, the relay device 820 comprises a first cache module and a second cache module which are sequentially arranged, the first cache module is used for releasing or caching the material belt 900, the second cache module is used for caching the material belt 900 when the first cache module releases the material belt 900, the second cache module is used for releasing the material belt 900 when the first cache module caches the material belt 900, the cutting device 830 is located at the downstream of the conveying path of the relay device 820, and the cutting device 830 comprises a cutting module which is used for cutting the material belt 900.
It can be understood that, the manufacturing of the battery cells needs to go through multiple process flows, so the material tape 900 may contact with various structures during conveying, the structures may apply an acting force to the material tape 900, in order to ensure the normal conveying of the material tape 900, the acting force applied to the material tape 900 by the downstream conveying structure needs to overcome the resultant force of the acting forces applied to the material tape 900 by the upstream structures, and the acting force applied to the material tape 900 by the downstream conveying structure also needs to provide a tension for the whole section of the material tape 900.
For example, in a pole piece composite cutting process, the strip 900 is first formed by lamination and then fed downstream for cutting to form a composite pole piece.
As the transport distance of the strip of material 900 increases, the length of the strip of material 900 increases, and the number of structures that apply force to the strip of material 900 increases, the downstream transport structures will need to provide more force to meet the tension requirements of the strip of material 900 and overcome the resultant force of the upstream structures on the strip of material 900.
On one hand, because the resultant force of the acting forces of the various structures on the material belt 900 may fluctuate, the downstream conveying structure is difficult to accurately realize stress balance, and the requirement for the output performance of the downstream conveying structure is increased along with the increasing tension requirement of the conveying distance. This may cause the downstream strip of material 900 to experience quality problems such as insufficient tensioning of the strip of material 900, arching of the strip of material 900, etc., resulting in poor cut quality of the strip of material 900.
On the other hand, the tape 900 needs to be relatively stationary with the cutting module when cutting, and the tape 900 needs to be repeatedly started and stopped during the conveying process, so that the conveying speed and the positioning accuracy of the tape 900 are reduced, and the cutting quality of the tape 900 is also deteriorated.
According to the composite pole piece cutting machine provided by the application, the processing speed and the cutting quality of the material belt 900 can be improved.
Specifically, on the one hand, the first buffer module buffers the upstream fed material tape 900 through a buffer action, and when the first buffer module buffers the material tape 900, the second buffer module actively releases the material tape 900 downstream, because the first buffer module receives the material tape 900 from the upstream at this time, and the second buffer module releases the material tape 900 that has been previously buffered in the relay device 820, the material tape 900 released by the relay device 820 and the material tape 900 received by the relay device 820 from the upstream are isolated from each other in terms of stress, and the cutting device 830 does not need to overcome the acting force of the composite device 810 on the material tape 900 when receiving the material tape 900, nor needs to provide tension for the material tape 900 upstream of the relay device 820, which is beneficial to improving the conveying precision of the material tape 900, and further improving the cutting quality.
On the other hand, when the compound device 810 continuously feeds the tape 900, and the second buffer module switches from releasing the tape 900 to buffering the tape 900, the tape 900 downstream of the relay device 820 is in a temporary stationary state, and the cutting device 830 cuts the tape 900 when the tape is stationary. The material belt 900 does not need to be repeatedly started and stopped, so that the positioning error generated when the material belt 900 is repeatedly started and stopped is avoided, and the processing speed and the cutting quality of the material belt 900 are further improved.
The first cache module and the second cache module may implement the functions of caching and releasing in various ways.
According to some embodiments of the present application, relay device 820 includes a plurality of rollers 110, the first buffer module includes a first buffer roller 210, the first buffer roller 210 is located between two rollers 110, the second buffer module includes a second buffer roller 310, and the second buffer roller 310 is located between two rollers 110. The first buffer roller 210 can be close to or away from the roller 110 to release or buffer the strip of material 900, and the second buffer roller 310 can be close to or away from the roller 110 to release or buffer the strip of material 900.
At this time, the first buffer module realizes buffer storage and release through the linear reciprocating motion of the first buffer roller 210, and the second buffer module realizes buffer storage and release through the linear reciprocating motion of the second buffer roller 310.
In some embodiments, the first buffer module includes a first guide rail and a first slider, the first slider is mounted on the first guide rail, the first buffer roller 210 is mounted on the first slider, the second buffer module includes a second guide rail and a second slider, the second slider is mounted on the second guide rail, and the second buffer roller 310 is mounted on the second slider. The first guide rail and the second guide rail can ensure that the first buffer roller 210 and the second buffer roller 310 move smoothly.

It can be understood that, since the thicknesses of the material tape 900 at various positions are not completely consistent, when the cutter 420 is excessively close to or far from the material tape 900, the force of the cutter 420 on the material tape 900 may exceed or fall below a design range, which affects the cutting effect, and may even cause the cutter 420 to accidentally collide with the structure of the material tape 900, at which time the third sliding table 450 can compensate for the situation that the cutter 420 is far from or close to the material tape 900, so as to control the force within a proper range.
In some embodiments, this is accomplished by the first resilient member 640, and the first resilient member 640 is configured to apply a force to the cutter mount 410 in a direction toward the strip of material 900.

The cutting module further includes a limiting member 470, and the limiting member 470 limits the stroke of the third sliding table 450 on the third sliding base, so as to prevent the third sliding table 450 from separating from the third sliding base.
