Abstract

A standing device for letting a battery cell stand includes: a pressure regulating apparatus; a standing cavity; a charging cavity, connected to a first end of the standing cavity, the charging cavity being connected to the pressure regulating apparatus; a conveying apparatus, penetratingly disposed in the standing cavity and the charging cavity and configured to convey the battery cell; and a charging cavity sealing gate, disposed between the charging cavity and the standing cavity, the charging cavity sealing gate being configured to be opened when the pressure in the charging cavity rises to the pressure in the standing cavity, so that the battery cell is conveyed to the standing cavity.

First claim

What is claimed is:

1. A standing device for letting a battery cell stand, comprising:
a pressure regulating apparatus;
a standing cavity;
a charging cavity, connected to a first end of the standing cavity, the charging cavity being connected to the pressure regulating apparatus;
a conveying apparatus, penetratingly disposed in the standing cavity and the charging cavity and configured to convey the battery cell; and
a charging cavity sealing gate, disposed between the charging cavity and the standing cavity, the charging cavity sealing gate being configured to be opened when the pressure in the charging cavity rises to the pressure in the standing cavity, so that the battery cell is conveyed to the standing cavity.

2. The standing device according to claim 1 ,
wherein the charging cavity sealing gate is configured to be closed after the battery cell is conveyed to the standing cavity, and the charging cavity is configured to be depressurized after the charging cavity sealing gate is closed;
the standing device further comprising:
a charging sealing cover, the charging sealing cover being disposed at an end of the charging cavity away from the standing cavity, and the charging sealing cover being configured to be opened after the pressure in the charging cavity is reduced, so as to put in the battery cell.

3. The standing device according to claim 1 , further comprising:
a discharging cavity, connected to a second end of the standing cavity, the discharging cavity being connected to the pressure regulating apparatus; and
a discharging cavity sealing gate, disposed between the standing cavity and the discharging cavity, the discharging cavity sealing gate being configured to be opened when the pressure in the discharging cavity rises to the pressure in the standing cavity, so as to convey the battery cell to the discharging cavity.

4. The standing device according to claim 3 ,
wherein the discharging cavity sealing gate is configured to be closed after the battery cell is conveyed to the discharging cavity, and the discharging cavity is configured to be depressurized after the discharging cavity sealing gate is closed;
the standing device further comprising:
a discharging sealing cover, the discharging sealing cover being disposed at an end of the discharging cavity away from the standing cavity, and the discharging sealing cover being configured to be opened after the pressure in the discharging cavity is reduced, so as to remove the battery cell.

5. The standing device according to claim 3 , further comprising:
a pressure recovery apparatus, the pressure recovery apparatus being in communication with the charging cavity and the discharging cavity respectively, so as to recover high pressure from one of the charging cavity and the discharging cavity to the other one.

6. The standing device according to claim 1 , wherein the charging cavity sealing gate comprises:
a gate body, the gate body being connected to the charging cavity and the standing cavity respectively, and the gate body being provided with a first opening in communication with the charging cavity and the standing cavity; and
a gate plate, movably disposed on the gate body and corresponding to the first opening, and configured to open or close the first opening.

7. The standing device according to claim 6 , wherein the conveying apparatus comprises a first sub-conveying apparatus and a second sub-conveying apparatus, and the first sub-conveying apparatus and the second sub-conveying apparatus are threaded in the charging cavity and the standing cavity respectively, wherein the first sub-conveying apparatus and the second sub-conveying apparatus are disposed at an interval to avoid the gate plate.

8. The standing device according to claim 1 , wherein the volume of the standing cavity is 1-20 times the volume of the charging cavity.

9. The standing device according to claim 1 , wherein the standing cavity is a segmented structure.

10. The standing device according to claim 1 , wherein the charging cavity and the standing cavity are cylindrical.

11. The standing device according to claim 1 , further comprising:
a tray clamp, disposed on the conveying apparatus and configured to place the battery cell.

12. The standing device according to claim 11 , wherein the tray clamp comprises:
a liquid injection mechanism, a liquid discharge port of the liquid injection mechanism being configured to align with a liquid injection port of the battery cell, so as to inject an electrolyte into the battery cell; and
a liquid injection clamp, the liquid injection clamp being configured to clamp the battery cell.

13. The standing device according to claim 12 , wherein an end of the liquid discharge port close to the liquid injection port is provided with a sealing member.
