AI Technical Summary

Technical Problem

In the laboratory, during the assembly process of stacked batteries, traditional turnover boxes cause difficulty in fixing the extreme ears, easy to squeeze and deform, and poor sealing, easy to be invaded by moisture, affecting battery performance.

Method used

A stacked core storage device is designed, including a box body with an opening facing upwards. There are notches passing through the electrode outlet on both sides of the box body. A plurality of teeth are provided on the inner side of the notch. The tooth part is clamped with spacers for isolating the upper and lower stacked cores. The end plate of the cover is connected to the outer wall of the box body to form a sealing structure.

Benefits of technology

Through this device, the pole ears of the stacked core can be accommodated in the notch and sealed by the end plate, avoiding the extrusion deformation of the pole ears during transportation, improving sealing properties, preventing moisture intrusion, and ensuring the normal progress of battery assembly and stable performance.

Abstract

The utility model discloses a stacked core storage device which comprises a box body with an upward opening and a cover body covering the opening of the box body, two first opposite sides of the box body are provided with notches for tabs to penetrate out, and the inner sides of the notches are provided with a plurality of tooth parts; an isolation piece for isolating the upper and lower laminated cores is clamped on the tooth part; the cover body comprises a top cover and end plates fixed on two first opposite sides of the top cover, and the end plates are clamped on the outer wall of the box body. According to the stacked core storage device provided by the utility model, the notches are formed in the two sides of the box body, and the end plates clamped on the outer wall of the box body are arranged at the two ends of the top cover, so that the tabs of the stacked cores can be accommodated in the notches and are sealed through the end plates, the tabs are prevented from being extruded when the stacked cores are transferred, and the convenience of short circuit measurement is improved; and the box body with the wedge-shaped structure and the cover body with the blunt structure increase the sealing performance of the device, so that the influence of water on the energy of the battery is avoided to a great extent.
