Referring to fig. 1 and 4, the pole piece combining device provided by the embodiment of the present application comprises a combining assembly and a guide assembly, wherein the combining assembly comprises a first combining roller 110 and a second combining roller 120 which are arranged at intervals, the guide assembly is located at the upstream of the combining assembly along the conveying direction of the diaphragm, the guide assembly comprises a first guide roller 210 and a second guide roller 220, the first guide roller 210 is located to enable a first diaphragm 510 passing through the first guide roller 210 to pass through the first combining roller 110 at a wrap angle smaller than 1 °, and the second guide roller 220 is located to enable a second diaphragm 520 passing through the second guide roller 220 to pass through the second combining roller 120 at a wrap angle smaller than 1 °.
First, the technical problems of the prior art will be further explained.
It will be appreciated that during compounding, the first membrane 510, the second membrane 520, and the pole piece 530 are fed into the compounding zone between the first compounding roller 110 and the second compounding roller 120 and form a composite tape 540 in the compounding zone.
When the first membrane 510 contacts the first composite roll 110, the first membrane 510 will adhere to the surface of the first composite roll 110 and will be transported forward following the rotation of the first composite roll 110, and when the second membrane 520 contacts the second composite roll 120, the second membrane 520 will adhere to the surface of the second composite roll 120 and will be transported forward following the rotation of the second composite roll 120. Due to the speed difference between the first and second composite rolls 110 and 120, the feeding speed of the first and second membranes 510 and 520 and the feeding speed of the composite strip 540 are difficult to be kept consistent.
Assuming that the feeding speed of the first membrane 510 is greater than the feeding speed of the composite tape 540, the larger the wrap angle, the more likely it is to cause the first membrane 510 to wrinkle.
According to the pole piece compounding device provided by the embodiment of the application, the guide assembly is arranged at the upstream of the compounding assembly, the first diaphragm 510 passes through the first guide roller 210 and goes to the compounding area between the first compounding roller 110 and the second compounding roller 120, the second diaphragm 520 passes through the second guide roller 220 and goes to the compounding area, the first guide roller 210 and the second guide roller 220 are arranged to change the angle of the first diaphragm 510 and the second diaphragm 520 sent into the compounding assembly, so that the first diaphragm 510 passes through the first compounding roller 110 at a wrap angle smaller than 1 degree, the second diaphragm 520 passes through the second compounding roller 120 at a wrap angle smaller than 1 degree, the influence of the rotating speed of the first compounding roller 110 and the second compounding roller 120 on pole piece compounding is reduced, and the compounding quality of the pole piece compounding device can be improved.
Taking the first membrane 510 as an example, the wrap angle should be understood as the angle between the position where the first membrane 510 starts to contact the first composite roll 110 and the position where the first membrane 510 is compounded, and referring to fig. 1, in an idealized design, the line connecting the centers of the circles of the first composite roll 110 and the second composite roll 120 passes through the position where the first membrane 510 is compounded.

At this time, the feeding speed of the first diaphragm 510 is not influenced by the rotating speed of the first compound roller 110, and the feeding speed of the second diaphragm 520 is not influenced by the rotating speed of the second compound roller 120, so that the influence of the rotating speeds of the first compound roller 110 and the second compound roller 120 on pole piece compounding can be reduced to the maximum extent.
