Abstract

An automatic weighing and sorting apparatus for battery electrode sheets is provided. The automatic weighing and sorting apparatus includes a conveying device, a weighing device, and a sorting device. The conveying device is configured to transfer a number of battery electrode sheets to the weighing device. The weighing device is configured to get a weight of each of the number of battery electrode sheets. The sorting device is configured to sort the number of battery electrode sheets based on the weight of each of the number of battery electrode sheets.

First claim

What is claimed is:

1 . An apparatus useful for automatically weighing and sorting battery electrode sheets comprising:
a weighing device configured to measure a weight of each of a plurality of battery electrode sheets; a conveying device configured to transfer the plurality of battery electrode sheets to the weighing device; and assorting device configured to sort the plurality of battery electrode sheets based on the weight of each of the plurality of battery electrode sheets measured by the weighing device.

2 . The apparatus of claim 1 , wherein the sorting device comprises a microporous suction cup and an automatic control device; the microporous suction cup is configured to grip each of the plurality of battery electrode sheets using suction or at least a partial vacuum from the weighing device, and the automatic control device is configured to sort the plurality of battery electrode sheets into different sorting stations based on the weight measured by the weighing device.

3 . The apparatus of claim 1 , further comprising a suction device, wherein the suction device is configured to grip the plurality of battery electrode sheets and place the plurality of battery electrode sheets on the conveying device.

4 . The apparatus of claim 1 , wherein a weighing surface of the weighing device is at a lower altitude than a conveying surface of the conveying device.

5 . The apparatus of claim 4 , wherein a height difference between the weight surface and the conveying surface ranges from about 1 mm to about 10 mm.

6 . The apparatus of claim 1 , wherein the weighing device is spaced from the conveying device.

7 . The apparatus of claim 6 , wherein a distance between the weighing device and the conveying device ranges from about 1 mm to about 2 mm.

8 . The apparatus of claim 1 , wherein the conveying device comprises a first guide rail and a second guide rail perpendicular to the first guide rail.

9 . The apparatus of claim 8 , wherein a height of the conveying surface on the second guide rail tends to decrease along a conveying direction.

10 . The apparatus of claim 9 , wherein a slope angle between the transfer surface on the second guide rail and a horizontal plane ranges from about 150° to about 170°.

11 . The apparatus of claim 8 , wherein the second guide rail comprises a first end and a second end, the first end of the second guide rail is connected to the first guide rail, and the weighing device is located at the second end of the second guide rail and spaced from the second end of the second guide rail.

12 . The apparatus of claim 1 , wherein the sorting device comprises a column guide, a bracket, a microporous suction cup, a rotation device, and an automatic control device configured to sort the plurality of battery electrode sheets into different sorting stations based on the weight measured by the weighing device; a first end of the column guide is connected to and driven by the rotation device; the bracket is connected to a second end of the column guide, and capable of rotating with rotation of the column guide.

13 . The apparatus of claim 12 , wherein the bracket comprises a third end and a fourth end, the third end of the bracket is connected to the column guide, and the fourth end of the bracket is suspended above the weighing device.

14 . The apparatus of claim 13 , wherein the microporous suction cup is located on the fourth end of the bracket.

15 . The apparatus of claim 13 , wherein the plurality of sorting stations surround the rotation device.

16 . The apparatus of claim 15 , wherein a carrying surface of each of the sorting stations is at a lower altitude than a weighing surface of the weighing device.

17 . The apparatus of claim 15 , wherein the plurality of sorting station are integrated with the rotation device and capable of rotating with the rotation device.
