Preferably, the scrap racks 5 are provided in two configurations, one located outside each of the two raw material racks 6 at the edge. When a core sheet on a raw material rack 6 fails inspection, the robot 2 moves the scrap core sheet to the scrap rack 5.

[0040] In order to improve the versatility of the transformer core pre-stacking device, it is preferred that at least two of the scrap rack 5, the raw material rack 6 and the workbench 7 are components with the same structure. Specifically, the raw material rack 6 and the workbench 7 have the same structure, the scrap rack 5 and the raw material rack 6 have the same structure, and the scrap rack 5 and the workbench 7 have the same structure.

Specifically, the bracket 1 is provided with a slide rail for the manipulator to slide back and forth, guiding the manipulator 2. Preferably, each manipulator 2 is equipped with multiple suction cups 3 to effectively grasp core sheets with a large area and extremely thin thickness. Specifically, the core sheets are single silicon steel sheets.

[0048] Based on the above solutions, the transformer core pre-stacking device also includes a visual recognition and measurement device for identifying the length and width of the core sheets. Specifically, the visual recognition and measurement device can effectively identify the width of the silicon steel sheets in millimeters to accurately determine the number of silicon steel sheets and complete the product pre-stacking.

[0053] Four-level pre-stacked core sheets: wide sheets are divided into two types: Ah1 + Ah2, and narrow sheets are divided into two types: Ak1 + Ak2.

[0054] When stacking the pieces formally, the wide and narrow pieces are stacked together, and by exchanging their positions, six (sixth level) or four (fourth level) peaks are stacked. When pre-stacking, the wide and narrow pieces need to be pre-stacked separately.

[0055]

[0056] When pre-stacking in multiple levels, each sheet type has a different width, but products of the same level have the same length.

[0057] Silicon steel sheets of different shapes that need to be pre-stacked are placed on the corresponding raw material racks through the set workbench 7. The sheets are selected according to the pre-stacking requirements through the visual recognition and measuring device. A robot 2 with multiple suction cups 3 is used to grab a single silicon steel sheet with a large area and extremely thin thickness and place it on the workbench 7. The stacking order and number of sheets are determined according to the design requirements, and they are pre-stacked one by one. After the specified pre-stacking height is completed, the sheets are moved out of the working area along the track from one side of the equipment to the next process.
