The implementation principle of the lamination system of the main transformer of the embodiment of the application is as follows: in use, each transport assembly 41 first adsorbs a plurality of silicon steel sheets 7 stacked on the corresponding raw material table 2 and places them on the corresponding positioning table 5, while each group of silicon steel sheets 7 is placed on the corresponding longitudinal conveyor belt 621 or transverse conveyor belt 612. Then, the longitudinal conveyor belt 621 and the transverse conveyor belt 612 both transport the corresponding silicon steel sheet 7 to one end of the self, and make the silicon steel sheet 7 located at the end of one end of the self abut against the corresponding longitudinal abutting frame 622 or the transverse abutting frame 611, and the subsequent silicon steel sheet 7 abuts against the previous silicon steel sheet 7, so that each silicon steel sheet 7 is positioned in the length direction of the longitudinal conveyor belt 621 or the transverse conveyor belt 612.

In this process, the longitudinal positioning frame 623 is driven by the corresponding longitudinal driving element 624 to move in a direction approaching the corresponding longitudinal abutting frame 622, and the silicon steel sheet 7 on the longitudinal positioning frame 623 is clamped and positioned. Meanwhile, the middle positioning frame 93 is driven by the linkage assembly 92 and the positioning piece 91, and the end positioning frame is moved towards the direction close to the silicon steel sheet 7 on the corresponding transverse conveyor belt 612 under the action of the end driving piece 642, so as to clamp the silicon steel sheet 7. After the clamping is completed, the longitudinal positioning frame 623, the end positioning frame and the middle positioning frame 93 return to the initial positions.

Then, the stacking mechanism 3 adsorbs and places the positioned silicon steel sheet 7 on the stacking table 1, meanwhile, in the stacking process of the stacking mechanism 3, the transportation assembly 41 transports the silicon steel sheet 7 on the raw material table 2 to the positioning table 5, and the positioning mechanism 6 and the positioning avoidance mechanism 9 on the positioning table 5 continuously position the silicon steel sheet 7, so that the efficiency of positioning the silicon steel sheet 7 is improved.

The foregoing are all preferred embodiments of the present application, and are not intended to limit the scope of the present application in any way, therefore: all equivalent changes in structure, shape and principle of this application should be covered in the protection scope of this application.
