AI Technical Summary

Technical Problem

When existing robotic arms are used to stack transformer cores, the sharp ends of silicon steel sheets can easily scratch the stacked sheets. Furthermore, the robotic arms have poor adaptability and adjustability to cores of different sizes, resulting in a decrease in the quality of the stacked product and a high cost.

Method used

The design incorporates a sliding rail, bracket, sheet transfer assembly, sheet pick-and-place crossbar, sheet catcher assembly, and sheet stacker. It utilizes a magnetic chuck to stably grip silicon steel sheets and uses an arc-shaped catcher to catch the sharp ends. Combined with a dual-station collaborative design, it efficiently sorts and stacks E-type and I-type sheets, and is highly adjustable.

Benefits of technology

This avoids the sharp ends of silicon steel sheets scratching the bottom sheet, improves the efficiency and accuracy of lamination, ensures the quality of the iron core, and enhances the equipment's adaptability and adjustability to iron cores of different specifications.

Abstract

The invention belongs to the technical field of transformer iron core lamination processing, and particularly relates to automatic lamination equipment for transformer iron cores, which comprises two sliding rails, the two sliding rails are parallel to each other and are fixed at the top of a support, two parallel sheet moving assemblies are slidably connected onto the sliding rails, and two ends of a cross beam of each sheet moving assembly are fixedly connected with linear motors. The two linear motors are slidably connected to the corresponding sliding rails, a pneumatic cylinder is fixedly connected to the cross beam, and the extending end of a piston rod of the pneumatic cylinder is fixedly connected with the fixing plate. The silicon steel sheets at the bottom can be prevented from being scratched when the sharp end parts of the silicon steel sheets droop when the silicon steel sheets are stacked, and the quality of an iron core is improved; e-shaped sheets and I-shaped sheets can be efficiently sorted and stacked; deformation, slippage or scattering of the sheets can be effectively prevented in the transferring and placing process, and the lamination uniformity is improved; and moreover, the suitability of stacking iron cores with different specifications is enhanced.
