Abstract: Aiming at the fact that the transformer′s inner core is stacked manually and problems that the production efficiency is low, the quality of product is uneven, a set of automatic silicon steel sheet lamination machine was designed. Aluminum profile was used as a frame of the device. The xyz coordinate was used as the movement mode. Stepper motors driving the synchronous belt and screw slide were used as the drive mode. Vacuum suction was used as the catch mode. TC55 controller was applied to control the lamination process. Structure optimization and vibration test were carried out to find the frequency of vibration resulting from loose base. The effective value of vibration acceleration and lamination accuracy was compared. The results indicate that structure optimization can reduce vibration resulting from loose base and meet accuracy requirement.
