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

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 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.

2 . The battery cell activation tray of claim 1 , wherein the elastic members 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 elastic members are a tensile spring.

4 . The battery cell activation tray of claim 1 , wherein the elastic members have one end mounted on an outer peripheral portion of the supporting portion, and the other end opposite the one end mounted on the outer peripheral portion of the jig located at an outermost position.

5 . The battery cell activation tray of claim 1 , wherein two or more elastic members are mounted at separate locations.

6 . The battery cell activation tray of claim 5 , wherein the elastic members are mounted at the outer peripheral portion of the jig at the same height from the upper surface of the base plate.

7 . The battery cell activation tray of claim 1 , wherein the elastic members are detachably mounted on the outer peripheral portion of the jig.

8 . The battery cell activation tray of claim 7 , wherein the outer peripheral portion of the jig to which the elastic member is mounted has a hook-shaped fixing portion with a circular structure having one open portion formed to which the elastic members are fixed.

9 . The battery cell activation tray of claim 1 ,
wherein an indented-shape groove parallel to an arrangement direction of the jigs is formed on the upper surface of the base plate, and 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.

10 . The battery cell activation tray of claim 9 , wherein the jig transferring portion is a roller mounted on the lower end portion of the jig corresponding to the indented-shape groove.

11 . The battery cell activation tray of claim 9 , 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.

12 . The battery cell activation tray of claim 11 , wherein a protrusion height of the guide is 10% to 90% relative to a depth of the indented-shape groove.

13 . 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.

14 . 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.

15 . 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.
