[0029] As Figures 1 to 5As shown, this embodiment of a battery cell insulation sheet conveying device includes a roller assembly 1, support members 2, and a conveying channel 3. The support members 2 are wound around the roller assembly 1, and several support members 2 are arranged parallel to and spaced apart along the axial direction of the roller assembly 1, thereby expanding the coverage area of ​​the support members 2. Each support member 2 is independently arranged and does not affect others. When the material belt 10 enters the conveying channel 3, the support members 2 are located below the material belt 10, thereby supporting the material belt and driving it forward. The roller assembly 1 includes rollers 1a to 1f, and the support members are sequentially wound around rollers 1a to 1f, so that the rotation of the rollers can drive the support members to move. Rollers 1a, 1b, and 1c are located on the same plane and parallel to the conveying channel 3. Specifically, rollers 1a, 1b, and 1c are located on a horizontal plane to facilitate cutting processing. A gap 20 is provided between rollers 1b and 1c, and the gap 20 is positioned corresponding to the cutting element 4. When the cutting element 4 is cutting, it is avoided by the gap 20. The cutting element 4 can be an existing tool such as a strip cutter or a transverse reciprocating cutter. Roller 1d is positioned below the gap 20, so that the second support section 22 between rollers 1b and 1d and the third support section 23 between rollers 1c and 1d are located below the conveying channel 3 and the gap 20, and the cutting element 4 will not cut into the second and third support sections when it descends. The support member 2 between rollers 1a and 1b forms a first support section 21, and the support member 2 between rollers 1c and 1e forms a fourth support section 24. The first support section 21 and the second support section 22 are located on both sides of the gap. When the cutting member 4 cuts the material strip 10 at the gap 20 position, the front material strip 101 is driven forward by the fourth support section 24, and the rear material strip 102 is conveyed forward by the first support section 21, so that both parts of the material strip can continue to move forward without compression. In this embodiment, roller 1a is the driving wheel, providing driving force, and the other rollers are driven wheels. In the above technical solution, the material strip 10 enters through the inlet end 31 of the conveying channel 3 and moves to the cutting member 4 for cutting. There are many examples of cutting devices for the cutting member 4 in the prior art, which will not be described in detail here. After being cut by the cutting component 4, the front strip 101 is driven forward by the fourth support section 24, and the rear strip 102 is driven forward by the first support section 21. Finally, they are collected after passing through the fourth support section 24. Through the above technical solution, collision and squeezing of the front and rear strips at the cutting position can be avoided, reducing the risk of deformation of the cutting edge.

The first support section 21 is provided with the rolling assembly 5 above, and the rolling assembly 5 is arranged upstream of the cutting member. The conveying channel 3 is arranged between the first support section 21 and the rolling assembly 5. The material belt 10 is pressed by the rolling assembly 5 from above, so that it can move forward in cooperation with the support. The rolling assembly includes a front roller 51 and a rear roller 52. The front roller 51 is arranged above the roller 1a, so that the material belt moves more smoothly. The front roller 51 and the rear roller 52 are connected by a connecting plate 53 at both ends. The connecting plate 53 is connected with a lifting cylinder 54. The lifting cylinder 54 drives the connecting plate 53 to rise or fall. The front roller and the rear roller can be synchronously lifted by the connecting plate 53 driven by the lifting cylinder 54, so that they can be adjusted according to the material belt of different thicknesses. In the embodiment, the support 2 is in a strip shape, and is made of elastic material, such as rubber, which has elasticity and certain anti-skid performance.
