High-speed detection device and method for defects of positive electrode and negative electrode of cylindrical battery

The invention provides a cylindrical battery positive and negative electrode defect high-speed detection device and method. The device comprises a detection disc, a high-speed visual detection device, a removal disc, a first arc-shaped limiting device, a magnetic attraction type notch, a removal device, a recovery disc, a discharging disc, a second arc-shaped limiting device and an industrial personal computer. Meanwhile, pictures of the positive end face and the negative end face of the battery on the detection disc are collected and transmitted to the industrial personal computer, the industrial personal computer splices the pictures of the positive end face and the negative end face of the battery into one picture and then inputs the picture into a battery defect detection network model, and defects of the positive electrode and the negative electrode of the battery are positioned and classified at the same time; and if it is recognized that defects exist, the industrial personal computer controls the remo
