Retired battery recycling and classifying treatment device and method

The invention relates to a retired battery recycling and classifying treatment device and method, and belongs to the technical field of battery recycling. Comprising a feeding mechanism, a detecting mechanism, a classifying mechanism, a code printing mechanism, a collecting mechanism and a recycling mechanism, the feeding mechanism is used for feeding retired batteries, the detecting mechanism is used for detecting the appearance of the fed batteries and dividing the fed batteries into usable batteries and scrapped batteries, and the classifying mechanism is used for carrying out charging and discharging tests on the usable batteries in the detecting mechanism; according to the charging and discharging time ratio of the batteries, the batteries are divided into recycled batteries and waste batteries, the code printing mechanism carries out grading and code printing on the recycled batteries according to the charging and discharging time ratio of the recycled batteries, the collecting mechanism collects the sc
