AI Technical Summary

Technical Problem

Existing secondary battery recycling devices lack a pre-detection unit, and the cutting trajectory relies on complex multi-axis coordination, which poses safety hazards and cutting deviations, leading to frequent shutdowns for calibration. This makes it difficult to meet the requirements of high reliability and low operation and maintenance costs for large-scale battery recycling.

Method used

A secondary battery cell material separation and recycling device was designed, integrating a temperature measurement zone, a voltage detection zone, an insulation resistance detection zone, and a tab support cutting zone. It uses an infrared thermometer, a voltage detection probe, and an insulation resistance detection probe for pre-detection, and a composite linkage cutting mechanism driven by a single-axis stepper motor to achieve cutting, eliminating multi-axis linkage errors.

Benefits of technology

It achieves triple detection of batteries before cutting, identifies and rejects unqualified batteries, avoids safety hazards, improves cutting quality, reduces downtime for calibration, lowers operation and maintenance costs, and meets the continuous and stable operation requirements of large-scale battery recycling.

Abstract

This invention relates to a secondary battery cell material separation and recycling device, belonging to the field of cell material separation technology. It includes a workbench with a temporary storage rack mounted on top. A guiding component is located on one side of the temporary storage rack. An infrared thermometer is located on the side of a first upright. Voltage and resistance detection probes are located on the sides of the second and third uprights, respectively. A laser cutting gun for cutting electrode tab supports is located on the side of a fourth upright. A conveyor frame is located on the outer side of the rear of the temporary storage rack, and a conveyor belt is installed inside the conveyor frame. A transfer component and a transfer frame are sequentially located on the side of the conveyor frame. This invention effectively eliminates potential hazards by integrating a pre-heat measurement and electrical performance testing unit. Furthermore, the coordinated structure of a linkage shaft, linkage plate, transmission shaft, and transmission plate achieves a trapezoidal cutting trajectory, effectively avoiding multi-axis misalignment, ensuring a precise and stable cutting trajectory, significantly reducing downtime for calibration, and improving the safety and efficiency of secondary battery recycling.
