Abstract
The invention discloses a bidirectional cutting main roller driving method based on an energy storage mechanism in the field of multi-line bidirectional cutting solar silicone wafer cutting. When a main roller starts to slow down, the rotating movement of a main shaft of the main roller is converted into the linear movement of a compression spring through an electromagnetic clutch, the compression process is the process of converting the rotating energy into the potential energy of the spring, after the main roller rotates backwards, the compressed spring reacts on the main shaft of the main roller through a transmission system, and the potential energy of the spring is converted into the rotating energy. By means of a spring accumulator, the kinetic energy of the main roller is converted into the potential energy of the spring in the slow-down process, and therefore the output torque of a driving motor is reduced; in the speed-up process, the potential energy of the spring is converted into the kinetic energy of the main roller, and therefore the output torque of a servo motor is reduced; in the speed-up and slow-down processes, the electric energy consumption is greatly reduced, and the running time of the speed-up and slow-down stages is remarkably shortened.
