Abstract

A stacking apparatus which is to be disposed downstream of a conveyer that conveys a plurality of electrode bodies and stacks the electrode bodies, the stacking apparatus comprising: a mounting plate disposed obliquely with respect to the electrode bodies conveyed by the conveyer, and on which the electrode bodies are stacked; a first wall section that is erected on the mounting plate and extends along the conveyance direction of the electrode bodies; and an insulating section forming means for forming an insulating section composed of an insulating material on side surfaces of the electrode bodies stacked on the mounting plate.

First claim

What is claimed is:

1 . A stacking apparatus which is to be disposed downstream of a conveyer that conveys a plurality of electrode bodies and stacks the electrode bodies, the stacking apparatus comprising:
a mounting plate disposed obliquely with respect to a conveyance direction in which the electrode bodies are conveyed by the conveyer, and on which the electrode bodies are stacked; a first wall section that is erected on the mounting plate and extends along the conveyance direction of the electrode bodies; and an insulating section forming means for forming an insulating section composed of an insulating material on side surfaces of the electrode bodies stacked on the mounting plate, wherein the insulating section forming means comprises:
an unwinding means for unwinding a film coated with an insulating material along the side surfaces of the electrode bodies; and
a winding means for winding up the film after transferring the insulating material onto the side surfaces of the electrode bodies.

2 . The stacking apparatus according to claim 1 , which further comprises a curing means for curing the insulating material.

3 . An electrode body production line that conveys and stacks a plurality of electrode bodies, comprising:
a conveyer that conveys the electrode bodies; and a plurality of the stacking apparatuses according to claim 2 , wherein the electrode body production line is configured to switch the stacking apparatuses such that, when a predetermined number of the electrode bodies are stacked on one of the stacking apparatuses, the electrode bodies are stacked on another one the lamination apparatuses.

4 . The stacking apparatus according to claim 1 , wherein each of the electrode bodies comprises a first negative electrode layer, a first solid electrolyte layer, a positive electrode layer, a second solid electrolyte layer, and a second negative electrode layer,
wherein each of the electrode bodies has a current collector that is formed of copper at its end portion in a stacking direction of the first negative electrode layer, the positive electrode layer and the second negative electrode layer.

5 . An electrode body production line that conveys and stacks a plurality of electrode bodies, comprising:
a conveyer that conveys the electrode bodies; and a plurality of the stacking apparatuses according to claim 4 , wherein the electrode body production line is configured to switch the stacking apparatuses such that, when a predetermined number of the electrode bodies are stacked on one of the stacking apparatuses, the electrode bodies are stacked on another one the lamination apparatuses.

6 . An electrode body production line that conveys and stacks a plurality of electrode bodies, comprising:
a conveyer that conveys the electrode bodies; and a plurality of the stacking apparatuses according to claim 1 , wherein the electrode body production line is configured to switch the stacking apparatuses such that, when a predetermined number of the electrode bodies are stacked on one of the stacking apparatuses, the electrode bodies are stacked on another one the lamination apparatuses.
