Background

The existing production technology of the transformer silicon steel sheet iron core roughly comprises the following modes:

firstly, silicon steel sheets are cut and stacked through a transverse shearing line, the transverse shearing line of the silicon steel sheets generally comprises a feeding device, a feeding channel, a punching device, a V-shaped shearing device, a collecting device and a control center, wherein the feeding device, the punching device, the V-shaped shearing device and the shearing device are sequentially arranged on the feeding channel, and the silicon steel sheets are manually transported to a stacking working place after being cut through the transverse shearing line and are manually stacked into an iron core;

silicon steel sheets are cut and stacked through a transverse shearing line, manually conveyed to a stacking working place, manually sorted (the silicon steel sheets are stacked in order), loaded into a preset station of automatic stacking equipment, and stacked into an iron core through the automatic stacking equipment.

For example, patent CN110415961A discloses a transformer silicon steel sheet stacking system, which relates to the technical field of transformer silicon steel sheet manufacturing equipment. It includes the closed assembly device body, has a closed assembly support on the closed assembly device body, has 2 at least groups on the closed assembly support and just positioner, 2 at least groups smart positioner, 1 at least closed assembly platform devices to and 2 at least groups sucking disc handling device, sucking disc handling device sets up sucking disc handling device including outside handling device and closed assembly handling device, just positioner, smart positioner top, sets up closed assembly platform device between the smart positioner, closed assembly handling device establishes the top at corresponding smart positioner and closed assembly platform device. When the silicon steel sheets are stacked, corresponding spacing adjustment and position fine positioning can be carried out according to silicon steel sheet iron cores of different specifications, the utilization rate is high, the arrangement of the silicon steel sheets in advance is not needed, and the stacking efficiency is high.

In the process of stacking the silicon steel sheets, the silicon steel sheet iron core is of a herringbone structure formed by three transversely distributed silicon steel sheets and two longitudinally distributed silicon steel sheets, and when stacking, the three transversely distributed silicon steel sheets need to be moved to the stacking position first, and then the two longitudinally distributed silicon steel sheets need to be moved to the stacking position (or the two longitudinally distributed silicon steel sheets are moved first, and then the three transversely distributed silicon steel sheets are moved), that is, the time of two steps of actions is needed to complete the stacking of the silicon steel sheet iron core every time, and the stacking efficiency is not high. Therefore, in order to improve the stacking efficiency, an idea is proposed that the suction cup simultaneously picks five silicon steel sheets at different positions to stack the silicon steel sheets, and the idea only needs one step of action to realize stacking, so that the stacking efficiency can be greatly improved. In order to realize the above assumption, when a worker implements the specific implementation, the worker finds that the positions of the silicon steel sheets need to be precisely positioned before the silicon steel sheets are stacked, and the existing precise positioning device can only independently and precisely position two silicon steel sheets distributed transversely or three silicon steel sheets distributed longitudinally, and cannot simultaneously and precisely position the silicon steel sheets at five different positions.
