Description

Technical Field

[0001] This invention relates to the field of lithium battery processing, and in particular to a multi-station cell positioning fixture and cell production line. Background Technology

[0002] After the formation and capacity testing stages in lithium battery manufacturing, the cells experience slight displacement within the formation and capacity testing fixtures. The entire cell assembly is then transferred from the formation fixture to the capacity testing fixture or a water-cooled unloading assembly by an overhead crane. If the cells shift position, it can lead to decreased stability and yield of downstream equipment, and even damage to the cells. Therefore, secondary positioning of the cell assembly is necessary. Positioning methods include horizontal double-sided clamping positioning, vertical bottom-support positioning, and air bag body clamping positioning to ensure the stability and accuracy of cell unloading. Existing cell fixtures generally suffer from low positioning accuracy, complex positioning structures, limited cell capacity, and high equipment costs when performing horizontal, vertical, and air bag positioning, affecting the quality of subsequent cell processing. Furthermore, existing technologies are cumbersome to operate in practice, with slow response times, severely impacting production efficiency and profitability.

The battery cell air bag clamping module 8 is used to drive the first air bag clamping component 83 and the second air bag clamping component 84 to move in the opposite direction through the air bag clamping drive cylinder 82 so as to use the first air bag clamping block 831 and the second air bag clamping block 841 to clamp the battery cell air bag. In specific implementation of this invention, when it is necessary to adjust the vertical support height of the battery cell, the transmission worm in the worm gear assembly 3 is rotated by the lifting adjustment handwheel 4. The transmission worm drives the transmission worm wheel to rotate, and the transmission worm wheel drives the lead screw in the lifting lead screw nut pair 2 to rotate. The lead screw drives the battery cell support plate 74 in the battery cell horizontal clamping module 7 to move vertically through the nut in the lifting lead screw nut pair 2, thereby realizing the adjustment and positioning of the battery cell in the vertical direction. It has the characteristics of simple structure and convenient operation. In actual implementation, it can reduce equipment costs, improve positioning accuracy and positioning efficiency, and improve processing quality and processing efficiency.When horizontal clamping and positioning of battery cells is required, the battery cell horizontal clamping module 7 clamps and positions two rows of battery cells horizontally through the first battery cell clamping and positioning component 71 and the second battery cell clamping and positioning component 72. This allows for simultaneous positioning of multiple battery cells, improving production efficiency. In this embodiment, this multi-station battery cell positioning fixture can simultaneously position 96 battery cells, significantly improving work efficiency. Furthermore, the airbag clamping drive cylinder in the battery cell airbag clamping module 8 drives the first airbag clamping component and the second airbag clamping component to move synchronously in opposite directions. This allows multiple first airbag clamping blocks 831 and multiple second airbag clamping blocks 841 to simultaneously clamp and position multiple battery cell airbags, resulting in fast response and high clamping and positioning efficiency, further enhancing production efficiency.
