[0035] The storage box 211 and the tension spring 216 are provided to facilitate the collection of the batteries with the plastic film cut off. When cutting, the right end of the battery will stick to the left side of the baffle 217. After the plastic film of the battery is cut off, the battery will fall onto the top of the buffer pad 212 through the shielding of the baffle 217 to buffer and prevent the battery from being damaged. Then the battery will be stored in the storage box 211. When the plastic film battery needs to be processed later, the storage box 211 can be directly pulled out of the slot 213 to take it out, which is very practical.

[0036] Meanwhile, the contents not described in detail in this specification belong to the prior art known to those skilled in the art, and the model parameters of each electrical appliance are not specifically limited, and conventional equipment can be used.

When the right side of the battery is attached to the left side of the baffle 217, it is also located at the infrared sensor 23 13, the infrared sensor 2313 will feed back information to the control module 2312, and then the control module 2312 will close the lower conveyor belt 232 and the upper conveyor belt 233, and at the same time start the cylinder 2311 to drive the cutter 237 to descend and cut the plastic film on the outside of the battery. After cutting, the control module 2312 controls the cylinder 2311 to reset the cutter 237, and at the same time starts the lower conveyor belt 232 and the upper conveyor belt 233 to drive the battery to continue to move to the right for the next cutting. At this time, the cut battery will fall to the top of the buffer pad 212 through the shielding of the baffle 217 for buffering to prevent the battery from being damaged. Then the battery will be stored in the storage box 211. When the plastic film battery needs to be processed subsequently, the storage box 211 can be directly pulled out of the slot 213 to take it out for subsequent processing.
