Abstract
A device for pressing at least one first joining partner against at least one second joining partner when joining battery cells and cell connectors during battery assembly. The device has several pneumatic pistons that are designed to form a shared gas volume during operation, and hold-down devices that are designed to be pressed simultaneously against the at least one first joining partner by the pneumatic pistons.
Claims15
A presser device for pressing at least one first joining partner against at least one second joining partner when joining battery cells and cell connectors during battery module assembly, comprising:
- a plurality of pneumatic pistons configured to form a shared gas volume during operation;
- and
- a plurality of hold-down devices configured to be pressed simultaneously against the at least one first joining partner by the plurality of pneumatic pistons.
A method for pressing at least one first joining partner against at least one second joining partner when joining battery cells with cell connectors as part of battery module assembly, the method comprising:
- pressing the at least one first joining partner against the at least one second joining partner with a plurality of hold-down devices,
- wherein the hold-down devices of the plurality of hold-down devices are each moved by pneumatic pistons which are supplied with a same pressure via a common pressure source.
