The invention discloses a disassembling device of a circuit board with components and parts and a disassembling method of the disassembling device. The disassembling device comprises a shell, a feeding
gate valve, an air outlet, an air inlet, a
soldering tin liquid discharging valve, a discharging
gate valve, a rotary separating cylinder, a vibration separating screen, an
electric heating device, a spring device, a
soldering tin liquid containing tank, a transmission shaft, a
vibration motor and a transmission motor, wherein the feeding
gate valve, the air outlet, the air inlet, the
soldering tin liquid discharging valve and the discharging gate valve are arranged on the shell, the rotary separating cylinder, the vibration separating screen, the
electric heating device, the spring device, the soldering tin liquid containing tank and the transmission shaft are arranged inside the shell, and the
vibration motor and the transmission motor are arranged outside the shell. A method integrating
electric heating and hot
air heating is used for controlling
internal temperature to be distributed evenly, a mode integrating the rotary separating cylinder, a baffle and the vibration separating screen is used for providing required disassembling force and forward power for the circuit board, and therefore it is guaranteed that soldering tin liquid and the components and parts efficiently fall off from the circuit board and are smoothly discharged. The disassembling device and the disassembling method achieve an even
heating temperature field, automatic and
continuous feeding and discharging and cyclic utilization of hot air, the whole
processing procedure is closed and cycled, and secondary
pollution will not be produced.
