The traditional manual iron core stacking method is labor-intensive and has low production efficiency, while the existing stacking production line is linearly distributed, occupies a large space and is difficult to ensure the consistency of stacking quality. Therefore, the development of a double-station iron core automatic stacking production line with high automation, high efficiency and stable quality has important practical significance and broad market prospects.

The two stations have the same structure and are arranged in a mirror image, and each station includes a yoke column feeding device, a yoke column pre-positioning area, a three-column feeding device, a three-column pre-positioning area, a core stacking position and a stacking center. The yoke column feeding device, the yoke column pre-positioning area, the core stacking position, the three-column pre-positioning area and the three-column feeding device are arranged in a U-shaped structure.

After the material tray is transported inwards, the three-column loading mechanism 31 is turned by the rotating platform 18, so that the three-column material tray is horizontally perpendicular to the yoke column material tray; after the loading is completed, the yoke column loading lifting mechanism 12 and the three-column loading lifting mechanism 17 are started to lift the material tray upward, so that the sheet material docks with the slicing mechanism (yoke column slicing mechanism 14, three-column slicing mechanism 19), and the slicing mechanism magnetically suspends multiple sheets of material, completing the yoke column and three-column slicing; when grabbing materials, the yoke column grabbing device 2 and the three-column grabbing device 8 are respectively moved horizontally to the top of the sheet splitting mechanism through their motion modules, and the corresponding grabbing arm moves downward to grab the sheet of the sheet splitting mechanism, and then moves horizontally to the pre-positioning mechanism, and the grabbing arm puts the sheet downward, and the yoke column double pre-positioning device 3 and the three-column double pre-positioning device 6 position the sheet to prepare for the next step; when stacking, the yoke column stacking device and the three-column stacking device operate interactively through the linear motor. First, the grabbing arm of the yoke column stacking device grabs the sheet of the yoke column pre-positioning device downward, and the two pairs of grabbing arms automatically adjust the width, and at the same time move horizontally to the double-station finished product output device to place the yoke column sheet on the stacking table. Then, the grabbing arm of the three-column stacking device grabs the sheet of the three-column pre-positioning device downward, and the grabbing arm automatically adjusts the width, and at the same time moves horizontally to the double-station finished product output device to place the three-column sheet on the stacking table to complete the iron core stacking.
