Abstract

The application provides a glue removing device based on a battery module, which comprises a rough glue removing mechanism, a fine glue removing mechanism and a driving mechanism, wherein in the discharging process of the battery module, battery discharging energy which is originally dissipated in a heat form is directly converted into glue removing mechanical energy, so that the energy recycling in the production process is realized, in the discharging process of the battery module, the physical process of reducing the motor rotating speed due to gradual falling of the voltage of a battery along with the reduction of an SOC (system on chip) is utilized, the process requirements of high-rotating-speed rough glue removing by the driving motor and low-rotating-speed fine glue removing by the driving motor are naturally matched, the process switching is realized without expensive servo systems, force sensors or complex algorithms in the process, the transition from rough glue removing to fine glue removing can be spontaneously realized, and the power switching between the rough glue removing mechanism and the fine glue removing mechanism is realized by utilizing the centrifugal force of a flyweight, and the process is realized by adopting pure mechanical, so that the reliability is strong.
