The invention discloses a Voice Coil Motor (VCM) magnetic sheet assembly device. The device comprises a bench, a feed system, a feeding system, a carrying system and a control system, wherein a feeding hole is arranged on the bench, the feed system which is used for feeding a magnetic sheet to the feeding hole is arranged at the position of the inside of the bench, which corresponds to the magnetic sheet installation position, the feeding system which is used for automatically assembling the magnetic sheet fed by the feed system to motors to be assembled is arranged at the position of the upper portion of the bench, which corresponds to the feeding hole, the carrying system which is used for fixing the motors to be assembled is arranged at the position of the lower portion of the bench, which corresponds to the feeding device, and the control system is used for controlling the working of the feed system, the feeding system and the carrying system. The feeding system which moves vertically is matched with a magnetic sheet feed system, magnets sheets which are required to be assembled are assembled to the carrying system for fixing the motors to be assembled one time, the carrying system is set to move along an X axis and a Y axis, a plurality of motor fixing groove for fixing motors to be assembled are fixedly arranged on a fixture carrier, a plurality of motors can be assembled continuously, and the production efficiency and the pass percentage are improved.
