Abstract

The invention discloses a precision control device of a vacuum laser welding machine for preparing sodium-sulfur batteries. The sealing performance of the sodium-sulfur batteries welded by the device can be improved, safety of the batteries is ensured, and safety use of the sodium-sulfur batteries is guaranteed. The technical scheme includes that the device comprises a rotary bracket, a positioning sleeve, a coupling transmission mechanism, a rotating block, a fixing sleeve, a hinge locking mechanism, a slewing mechanism, an ejector mechanism and a control transmission mechanism, a plurality of batteries are sequentially placed into a battery cavity in a vacuum box, the rotating block of the coupling transmission mechanism is inserted into a fixing sleeve matching groove for the batteries in an aligned manner through motors of the slewing mechanism and the control transmission mechanism so that the batteries are completely coupled with an end cap, the slewing mechanism drives the batteries to rotate at a uniform speed, the end cap is fixed by the positioning sleeve, and a battery housing is pushed at a position at which the battery housing is matched with the end cap to be welded with the end cap so that a welding track position is fixed.

Description

technical field [0001] The invention relates to a welding precision control technology, in particular to a precision control device for a vacuum laser welding machine used for preparing sodium-sulfur batteries. Background technique [0002] Sodium-sulfur batteries are based on β(β″)-Al 2 o 3 Ceramics are the electrolyte and diaphragm, sulfur and metal sodium are the positive and negative electrodes, and it is a fully sealed secondary battery that is all solid at room temperature. [0003] Beginning in the late 1980s and early 1990s, foreign countries focused on the development of sodium-sulfur batteries as applications in fixed occasions (such as power station energy storage), and more and more showed their superiority, such as the joint development of Japan's Tokyo Electric Power Company (TEPCO) and NGK Sodium-sulfur batteries are used as energy storage batteries, and their application targets are aimed at power station load leveling (that is, they play the role of peak s...
