[0039] The present invention also provides a steel stacking method, which uses a steel stacking system. The steel stacking system includes an electromagnetic holding device of the above structure. The steel stacking method includes the following steps:

[0040] S101, during the coding process, the steel row moves to the bottom of the electromagnetic holding device, and the magnetic tongue body 2-2-3-1 extends downward toward the outside of the magnetic guide plate body 2-2-1;

[0041] S102, the feeding device 9 lifts the steel row until it contacts the working surface of the electromagnetic chuck body 2-1, and at the same time, the steel pushes the magnetic tongue body 2-2-3-1 that it contacts upward;

[0043] like Figure 6As shown, in the above step S101, during the coding process, the steel row runs to the bottom of the electromagnetic holding device. The steel row is formed by a plurality of steels arranged side by side. All the steels in the steel row are in a parallel state. The length direction of the steel is parallel to the width direction of the electromagnetic suction cup body 2-1. The electromagnetic suction cup body 2-1 is in a horizontal state.

The working surface of the electromagnetic suction cup body 2-1 is the bottom surface of the electromagnetic suction cup body 2-1, and the magnetic tongue body 2-2-3-1 extends toward the bottom of the magnetic guide plate body 2-2-1.

[0044] like Figure 7 As shown, in the above step S102, the feeding device 9 lifts the steel row and moves it upward until the steel contacts the working surface of the electromagnetic chuck body 2-1, and the steel contacts the magnetic tongue body 2-2-3-1. The steel applies upward pressure to the contacted magnetic tongue body 2-2-3-1, and pushes the magnetic tongue body 2-2-3-1 into the interior of the magnetic plate body 2-2-1. Each steel of the steel row contacts the continuous multiple magnetic tongue bodies 2-2-3-1 on the magnetic plate assembly, and the continuous multiple magnetic tongue bodies 2-2-3-1 on each magnetic plate assembly that contact the steel are multiple magnetic tongue bodies 2-2-3-1 arranged sequentially and continuously along the length direction of the magnetic plate body 2-2-1. The continuous multiple magnetic tongue bodies 2-2-3-1 automatically form a group of fixed steel row arrangements on the upper surface of the steel.

[0045] like Figure 7 As shown, in the above step S103, after the electromagnetic holding device is powered on, it holds the steel section and the magnetic tongue assembly fixes the original arrangement shape of the steel section. After reaching the discharge position, the electromagnetic holding device is powered off, the steel section is separated from the electromagnetic holding device, and each active magnetic tongue assembly 2-2-3 is restored to its original state under the action of the elastic element 2-2-3-3.

[0046] The present invention also provides a steel stacking method, which uses a steel stacking system. The steel stacking system includes an electromagnetic holding device of the above structure. The steel stacking method includes the following steps:

[0047] S201, during the reverse code process, the steel row moves to the front and upper part of the electromagnetic holding device, and at the same time, the electromagnetic chuck assembly 2 turns 180 degrees, so that the working surface of the electromagnetic chuck body 2-1 faces upward, and the magnetic tongue body 2-2-3-1 extends upward toward the outside of the magnetic guide plate body 2-2-1;

[0048] S202, the electromagnetic holding device moves forward and enters under the row of steel sections, and the loading device 9 descends to place the row of steel sections on the working surface of the electromagnetic chuck body 2-1, and at the same time, the magnetic tongue body 2-2-3-1 that the steel sections contact moves downward;

[0050] S204, the electromagnetic suction cup assembly 2 is turned over 180 degrees again, so that the steel row is under the electromagnetic suction cup assembly 2, and the reverse code suction is completed.

[0051] like Figure 8 and Fig. 9 As shown, in the above step S201, during the reverse code process, the feeding device 9 lifts the steel row to the front and upper part of the electromagnetic holding device, and at the same time the electromagnetic suction cup assembly 2 flips 180° counterclockwise, and the electromagnetic suction cup body 2-1 is in a horizontal state. At this time, the length direction and width direction of the electromagnetic suction cup body 2-1 are both horizontal directions, the working surface of the electromagnetic suction cup body 2-1 is the top surface of the electromagnetic suction cup body 2-1, and the magnetic tongue body 2-2-3-1 extends toward the top of the magnetic guide plate body 2-2-1.

[0052] like Fig.10 As shown, in the above step S202, the feeding device 9 descends, and the steel row falls on the working surface of the electromagnetic chuck body 2-1. At the same time, under the action of the gravity of the steel, the movable magnetic tongue assembly in contact with the lower surface of the steel is pressed into the magnetic plate body 2-2-1 until the steel contacts the working surface of the electromagnetic chuck body 2-1. Multiple groups of movable magnetic tongue assemblies 2-2-3 automatically form a group of arrangement forms for holding the steel row on the lower surface of the steel. After the electromagnetic holding device is powered on, the electromagnetic holding device holds the steel row and the magnetic tongue assembly fixes the original arrangement shape of the steel.

[0053] like Fig.11 As shown, in the above step S204, the electromagnetic chuck assembly 2 turns 180° clockwise, and the steel row changes its spatial posture, which meets the technical requirements of the steel stacking holding state in the reverse stack. After reaching the discharge position, the electromagnetic holding device is powered off, the steel is separated from the electromagnetic holding device, and each active magnetic tongue component 2-2-3 is restored to its original state under the action of the elastic element 2-2-3-3.
