Abstract

A secondary battery cell module-type activation tray for transferring and charging a plurality of battery cells in a manufacturing process of a secondary battery, including a plurality of module trays that are embedded from one side opened to accommodate a plurality of battery cells in a plurality of rows to another side opposite thereto, the battery cells being disposed in a respective module tray, and each of the module trays has a structure that can be coupled or separated as extended in one direction or multiple directions in a plan view.

First claim

The invention claimed is:

1. A secondary battery cell module-type activation tray for transferring and charging a plurality of battery cells in a manufacturing process of a secondary battery, the activation tray comprising:
a first module tray recessed from one surface opened to accommodate a plurality of the battery cells in a plurality of rows to another surface opposite thereto;
a second module tray recessed from the one surface to accommodate a plurality of the battery cells in a plurality of rows to another surface opposite thereto; and
a third module tray recessed from the one surface opened to accommodate a plurality of the battery cells in a plurality of rows to another surface opposite thereto,
wherein each of the battery cells are disposed within a respective one of the module trays,
wherein the first module tray, the second module tray, and the third module tray extend in one direction or multiple directions on a plane so as to be engageable or detachable with each other,
wherein each of the first module tray, the second module tray and the third module tray comprises a first sidewall, a second sidewall, a third sidewall, and a fourth sidewall formed along an outer periphery of a tray bottom plate, and each of the first module tray, the second module tray and the third module tray is assembled through the respective first sidewall, the second sidewall, the third side wall and the fourth sidewall, and
wherein each first sidewall forms a groove having a concave shape extending outwardly, and each third sidewall forms a protrusion having a convex shape extending outwardly, to thereby form a slide fastening structure in which adjacent module trays are engageable and separable.

2. A secondary battery cell module-type activation tray for transferring and charging a plurality of battery cells in a manufacturing process of a secondary battery, the activation tray comprising:
a first module tray recessed from one surface opened to accommodate a plurality of the battery cells in a plurality of rows to another surface opposite thereto;
a second module tray recessed from the one surface to accommodate a plurality of the battery cells in a plurality of rows to another surface opposite thereto; and
a third module tray recessed from the one surface opened to accommodate a plurality of the battery cells in a plurality of rows to another surface opposite thereto,
wherein each of the battery cells are disposed within a respective one of the module trays,
wherein the first module tray, the second module tray, and the third module tray extend in one direction or multiple directions on a plane so as to be engageable or detachable with each other,
wherein each of the first module tray, the second module tray and the third module tray comprises a first sidewall, a second sidewall, a third sidewall, and a fourth sidewall formed along an outer periphery of a tray bottom plate, and each of the first module tray, the second module tray and the third module tray is assembled through the respective first sidewall, the second sidewall, the third side wall and the fourth sidewall, and
wherein each first sidewall forms a protrusion having a convex shape extending outwardly, and each third sidewall forms a groove having a concave shape extending outwardly, to thereby form a slide fastening structure in which adjacent module trays are engageable and separable.
