Embodiment Construction

[0042] First, a first embodiment of the present invention will be described.

[0043] figure 1 A perspective view showing a stack assembly 105 of the battery cell 100 used in the first embodiment. The stack assembly 105 used in the battery unit 100 is formed by constraining a plurality of stacked cells 103 with two end plates 101 and four constraining parts 102 . The weight of each single cell 103 is about 1 kg, and the stack assembly 105 uses a dozen to several tens of single cells 103 , so the battery unit 100 weighs several tens of kg. The stacked assembly 105 is formed by pressing both sides of the stacked cells 103 with the end plates 101 and combining the four constraining parts 102 .

Abstract

In order to provide an assembly palette for a secondary battery that can support plural types of secondary batteries, an assembly palette (200) for a secondary battery is used for a secondary battery having end plates (101) disposed on both ends of battery cells (103) that are lined up and a lower case (110) disposed on the bottom. This assembly palette (200) has a main positioning pin (201) and an auxiliary positioning pin (202) which determine the position of the end plates (101), seating face pins (203) that support the secondary battery stack assembly (105), and a base (210). The main positioning pin (201) is affixed to the base (210), and the auxiliary positioning pin (202) is held movably in the base (210).

Description

technical field [0001] The present invention relates to a technique for commonizing a tray in an assembly process of a secondary battery, especially when manufacturing various types of battery packs in which end plates hold side portions of stacked modules of secondary batteries on a production line. Background technique [0002] In recent years, in view of the international situation and environmental issues, various hybrid vehicles, electric vehicles, and other vehicles equipped with large-capacity secondary batteries have been sold. In addition, it is believed that this trend will continue in the future, and it is predicted that the types of vehicles equipped with secondary batteries with larger capacities will increase. Therefore, it is necessary to have various sizes of the secondary battery, and the tray for holding the secondary battery on the production line for assembling the secondary battery also needs to cope with this situation. [0003] Since the availability ...
