Referring to fig. 1 and 2, the embodiment provides a battery separator flattening device 100, which includes a plurality of upper rollers 110 and a plurality of lower rollers 120 connected in a transmission manner, the upper rollers 110 and the lower rollers 120 are arranged in parallel, a surface of the upper rollers 110 and a surface of the lower rollers 120 are used for threading a battery separator 103, two ends of the upper rollers 110 are respectively provided with a flattening assembly 130, the flattening assembly 130 is located between the upper rollers 110 and the lower rollers 120, the flattening assembly 130 includes a supporting body 132, and the supporting body 132 is used for supporting two side edges of the battery separator 103.
Specifically, the battery separator flattening device 100 is disposed at the extraction tank, and as an example, the upper roller 110 may be located above the liquid level of the extraction liquid, and the lower roller 120 may be located below the liquid level of the extraction liquid, so as to facilitate the stretching extraction of the battery separator 103. The battery diaphragm 103 is driven to stretch and move forward when the upper roller 110 and the lower roller 120 rotate by the tension of the surface of the upper roller 110 and the surface of the lower roller 120 on the battery diaphragm 103.
In the asynchronous stretching production process of the wet-process diaphragm, the diaphragm enters an extraction tank after being stretched transversely, and the thickness of the position clamped by the chain clamp is usually much thicker than that of the battery diaphragm 103 stretched in the middle due to the chain clamp at the edge part. At this time, the supporting body 132 can provide a larger tension force to the two side edges of the battery diaphragm 103, so that the battery diaphragm 103 is stressed and flattened, and wrinkling and curling phenomena after entering the extraction tank are avoided.
The embodiment of the utility model provides a battery diaphragm exhibition paper-back edition is put 100, through transmission connection and parallel arrangement's last roller 110 and lower roller 120, when battery diaphragm 103 in last roller 110 surface and lower roller 120 surface threading, make the tensile force of the different positions department of battery diaphragm 103 tend to unanimity, promote battery diaphragm 103's stability. Through the flattening assemblies 130 arranged at the two ends of the upper roller 110 and between the upper roller 110 and the lower roller 120 and the supporting bodies 132, when the battery diaphragm 103 is threaded on the surface of the upper roller 110 and the surface of the lower roller 120, the supporting bodies 132 can support the two side edges of the battery diaphragm 103, so that the problem that the battery diaphragm 103 is wrinkled due to insufficient tension on the two sides of the battery diaphragm 103 is solved. In addition, the additional tensioning effect of the supporting body 132 on the battery diaphragm 103 enables the edges of the two sides of the battery diaphragm 103 to be smoother, avoids the wrinkling and curling phenomena, and is beneficial to improving the production quality of the battery diaphragm 103.

Illustratively, when the tension is excessive, the ellipsoidal support can be rotated so that the surface of the ellipsoidal support with a shorter axial length is supported by the battery separator 103; when the tension is too small, the ellipsoidal support body can be rotated to support the surface of the ellipsoidal support body with a longer axial length and the battery diaphragm 103, so that the requirements of different tensions are met, and the phenomena of wrinkling and curling in the production process of the battery diaphragm 103 are better eliminated.
As shown in fig. 3, the flattening assembly 130 further includes a position adjusting turntable 133 and a screw rod 134 which are in transmission connection, and a slider 135 arranged on the screw rod 134, and the ellipsoidal support body is connected with the slider 135 through a connecting rod 136, wherein the extending direction of the screw rod 134 is consistent with the extending direction of the upper roller 110.
Specifically, the position adjustment dial 133 drives the screw rod 134 to rotate, and when the screw rod 134 rotates, the slider 135 arranged on the screw rod 134 moves along the screw rod 134, and the specific movement form is the same as that of the linear guide. At this time, the ellipsoidal support body connected to the slider 135 through the connecting rod 136 can rotate following the slider 135. The connecting rods 136 can be arranged in pairs and can be clamped at two opposite sides of the ellipsoidal support body, so that the ellipsoidal support body can be driven by the connecting rods 136 to move synchronously along with the sliding block 135. By adopting the above form, in the actual production process, the position of the ellipsoidal support body can be adjusted according to the battery diaphragm 103 with different specifications, so that the ellipsoidal support body corresponds to the two side edges of the battery diaphragm 103, the operation is convenient, and the adjustment difficulty is reduced.

In addition, the angle adjusting turntable 137 and the position adjusting turntable 133 do not interfere with each other, and the connecting rods 136 can be arranged in pairs and can be clamped at two opposite sides of the ellipsoidal support body, and gaps are formed at the clamping positions of the connecting rods 136 and the ellipsoidal support body, so that the ellipsoidal support body can be driven to move together, and the rotational degree of freedom cannot be limited. Thus, the state of the ellipsoidal support can be adjusted as needed.
When the tension at the edges of the two sides of the battery diaphragm 103 is insufficient as shown in fig. 4, the rotation angle of the ellipsoidal support can be adjusted so that the long axis of the ellipsoidal support is perpendicular to the plane of the battery diaphragm 103, thereby increasing the tension. When the tension is too high, an adjustment can be made in the form of fig. 5 or 6 to achieve the desired tension. The specific adjustment range is that the major axis of the ellipsoidal support is perpendicular to the plane of the battery separator 103 (where the maximum tension is provided) and the minor axis of the ellipsoidal support is perpendicular to the plane of the battery separator 103 (where the minimum tension is provided). And particularly, flexible adjustment can be performed according to the actual production condition. The tensile force of the ellipsoidal support body for lifting the battery diaphragm 103 can also avoid the phenomenon that the upper roller 110 or the lower roller 120 slips due to insufficient tensile force, thereby being beneficial to improving the stability during production and improving the production quality.
Alternatively, as shown in fig. 3, a scale (not shown in fig. 3) is provided on the position adjustment dial 133 for indicating the moving displacement of the slider 135.

Specifically, when the ellipsoidal support body has an ellipsoidal structure, an ellipsoidal equation x is satisfied2/a2+y2/b2+ z2/c2 is 1, where a and b are the equatorial radii (along the x and y axes), c is the polar radius (along the z axis), a, b and c are all normal numbers, and a > b > c. In actual manufacturing, the battery separator 103 may not be of a standard ellipsoidal structure but may be of an ellipsoidal-like structure due to the influence of manufacturing accuracy and the like, and may also prevent the problem of wrinkling and curling of the battery separator.
Optionally, the ellipsoidal support comprises a drum-shaped roller or a roller with an elliptical cross-section.
Specifically, the waist drum type roller is a roller with a larger central diameter and smaller diameters at two ends, and can be regarded as a roller formed by cutting off two ends of an ellipsoid. Similarly, the cross section of the roller can be elliptical, so long as the roller can effectively support the two side edges of the battery diaphragm 103 and adjust the tension.
Optionally, the ellipsoidal support is a stainless steel material. For example, grade 304 stainless steel can be used, which can play a role in rust prevention, corrosion resistance and the like, so that the ellipsoidal support body is more stable in use.
