Abstract

The present disclosure provides a battery cell activation tray which is an activation tray configured to accommodate battery cells during an activation process of the battery cells and has a structure including a base plate having a plate-type structure in which a plurality of battery cells are located on an upper surface thereof and a supporting portion of a partition wall structure protruding at one end in an upper surface direction, a plurality of jigs located on the upper surface of the base plate and separated from each other at a predetermined interval, and one or more elastic members mounted on the jigs to adjust separation distances between the jigs by elasticity, at both of opposite outer peripheral portions.

First claim

The invention claimed is:

1. A battery cell activation tray which is an activation tray configured to accommodate battery cells during an activation process of the battery cells, comprising:
a base plate having a plate-type structure in which a plurality of battery cells are located on an upper surface thereof and a supporting portion of a partition wall structure protruding at a first end of the base plate in an upper surface direction;
a plurality of jigs located on the upper surface of the base plate and separated from each other at a predetermined interval; and
a first elastic member mounted on a first side of the jigs to adjust separation distances between the jigs by elasticity; and
a second elastic member mounted on a second side of the jigs opposite the first side to adjust the separation distances between the jigs by elasticity,
wherein an indented-shape groove parallel to a stacking direction of the jigs is formed on the upper surface of the base plate along a substantially entire length of the base plate,
wherein a jig transferring portion for transferring the jigs along the indented-shape groove is formed at a lower end of the jig corresponding to the indented-shape groove in a state in which at least a part of the lower end of the jig is seated in the indented-shape groove, and
wherein at least one of the first elastic member and the second elastic member has a first end mounted on an outer peripheral portion of the supporting portion, and a second end opposite the first end of the at least one of the first elastic member and the second elastic member mounted on an outer peripheral portion of the jig located at a second end of the base plate opposite the first end of the base plate.

2. The battery cell activation tray of claim 1 , wherein the first elastic member and the second elastic member apply an attraction force to the jigs to close the separation distance between the jigs.

3. The battery cell activation tray of claim 1 , wherein the first elastic member and the second elastic member are tensile springs.

4. The battery cell activation tray of claim 1 , wherein the first elastic member and the second elastic member are provided in plurality such that two or more of the first elastic members and two or more of the second elastic members are mounted at separate locations.

5. The battery cell activation tray of claim 4 , wherein the first elastic members-and the second elastic members are mounted at the outer peripheral portion of the jigs at the same height from the upper surface of the base plate.

6. The battery cell activation tray of claim 1 , wherein the first elastic member and the second elastic member are detachably mounted on the outer peripheral portion of the jigs.

7. The battery cell activation tray of claim 6 , wherein the outer peripheral portion of the jig at the second end of the base plate has a hook-shaped fixing portion with a circular structure having one open portion formed to which the at least one of the first elastic member and the second elastic member is fixed.

8. The battery cell activation tray of claim 1 , wherein the jig transferring portion is a roller mounted on the lower end portion of the jig corresponding to the indented-shape groove.

9. The battery cell activation tray of claim 1 , wherein the jig transferring portion is a guide protruding from the lower end of the jig corresponding to the indented-shape groove to be inserted into the indented-shape groove.

10. The battery cell activation tray of claim 9 , wherein a protrusion height of the guide is 10% to 90% relative to a depth of the indented-shape groove.

11. The battery cell activation tray of claim 1 , wherein the battery cell includes positive and negative electrode terminals having one side protruding to the outer peripheral portion, and the positive and negative electrode terminals are accommodated and arranged in the upper surface direction opposite the base plate.

12. The battery cell activation tray of claim 1 , wherein a height of the jig corresponding to a protruding direction of the supporting portion is 50% to 100% relative to a length of the battery cell corresponding to the height of the jig.

13. The battery cell activation tray of claim 1 , wherein a width of the jig perpendicular to the protruding direction of the supporting portion is 110% to 150% relative to a width of the battery cell corresponding to the width of the jig.
