[0037] The pushing structure includes a push plate 26, which is fixedly installed above the fixed block 24. The push plate 26 is inclined. A slide bar 28 is arranged above the push plate 26. The slide bar 28 slides through the turntable 7. A mounting block 27 is arranged above the turntable 7. The lower end of the mounting block 27 is inclined. The mounting block 27 and the slide bar 28 are in contact and fit. The mounting block 27 and the fixed frame 5 are fixedly connected.

[0038] Specifically, a movable groove 30 is opened on the side of the fixed block 24, and a No. 3 spring 31 and a positioning block 29 are movably installed in the movable groove 30 from the inside to the outside. The positioning block 29 slides through the mounting frame 23 and extends to the outside of the mounting frame 23. A push block 32 is hinged on the top of the workbench 1, and the push block 32 is in contact with the positioning block 29.

[0039] Working principle: The insulating material 3 is installed above the supporting plate 2. The hydraulic cylinder 4 can drive the insulating material 3 to move intermittently above the workbench 1 through the supporting plate 2. The iron core is placed on the workbench 1. The iron core is located below the suction cup 10. Under the action of the support frame 8, the electric push rod 9 is connected to the external power supply. The electric push rod 9 drives the fixed frame 5 to rise and fall inside the support frame 8. When the fixed frame 5 moves downward, it drives the suction cup 10 to move synchronously. The suction cup 10 contacts the uppermost iron core and adsorbs the iron core.

[0040] Specifically, when the fixing frame 5 moves downward, it can drive the fixing block 24 to move synchronously. When the suction cup 10 stops moving, the fixing block 24 drives the adjusting plate 13 to move downward. Since the shaft 17 and the pipe 11 are fixedly connected, when the adjusting plate 13 approaches the shaft 17, the angle between the two sets of connecting rods 16 gradually increases. At this time, the slider 15 slides on the outer surface of the rod 14, and the No. 1 spring 18 is deformed by the force, thereby driving the piston plate 12 to move inside the pipe 11 toward the direction of the shaft 17. When the piston plate 12 moves, it can extract the air between the suction cup 10 and the iron core, so that the connection between the suction cup 10 and the iron core is tighter, which is conducive to increasing the stability of the suction cup 10 when picking up the iron core.

[0041] When the adjustment plate 13 moves to a certain position, the No. 2 spring 21 pushes the limit block 19 out from the inside of the groove 20, so that the limit block 19 can pass through the pipe 11, thereby facilitating the fixing of the adjustment plate 13 and the pipe 11 together, so that the suction cup 10 will not separate from the iron core when it moves upward.

[0042] Furthermore, when the suction cup 10 moves upward to a certain position, the motor 6 drives the turntable 7 to rotate under the action of the fixed frame 5, thereby driving the suction cup 10 to rotate around the motor 6. During this process, the slide bar 28 contacts the mounting block 27. Since the lower end surface of the mounting block 27 is inclined, the mounting block 27 can push the slide bar 28 to move downward. At this time, the slide bar 28 drives the fixed block 24 to rotate ninety degrees around the rotating shaft 25 through the push plate 26. At this time, the suction cup 10 drives the iron core to rotate from a horizontal state to a vertical state.

[0043] At the same time, the No. 3 spring 31 pushes the positioning block 29 out from the inside of the movable groove 30, so that the positioning block 29 can pass through the mounting frame 23, thereby maintaining the vertical state of the iron core. When the iron core moves to the top of the insulating material 3, the fixing frame 5 drives the iron core to move downward, and the suction cup 10 inserts the iron core between two adjacent groups of insulating materials 3. During this process, the pipe 11 is in contact with the adjusting block 22. The adjacent sides of the two groups of adjusting blocks 22 are funnel-shaped, which can increase the stability of the pipe 11, so that the iron core will not shake when inserted, and the adjusting block 22 can push the limit block 19 into the inside of the groove 20, so that the adjusting plate 13 and the pipe 11 can be movably connected. Under the action of the No. 1 spring 18, the piston plate 12 and the adjusting plate 13 move away from each other. At this time, the air inside the pipe 11 is pushed between the suction cup 10 and the iron core, so that the iron core can be separated from the suction cup 10.

[0044] After separation, the suction cup 10 moves upward to a certain position, and the turntable 7 drives the suction cup 10 to rotate. During rotation, the push block 32 contacts the positioning block 29 and pushes the positioning block 29 into the movable groove 30. At this time, under the action of gravity, the suction cup 10 can fall under the mounting frame 23, so that the suction cup 10 can adsorb and pick up the iron core again.

[0045] It should be noted that there are two groups of suction cups 10. When one group of suction cups 10 is taking the iron core, the other group of suction cups 10 can insert the taken iron core between the insulating materials 3, which is beneficial to improve the efficiency of the iron core lamination.
