[0035] A frame 1, wherein two support panels arranged on the left and right are connected to the upper surface of the frame 1, wherein at least one of the support panels is a movable support panel 3, and the movable support panel 3 is connected to the frame 1 rotatably or vertically movably through a connecting mechanism;

[0036] An elastic support body 6, at least one set of the elastic support body 6 is provided, the elastic support body 6 is fixed on the frame 1 under the movable support panel 3, and the top of the elastic support body 6 is in contact with the movable support panel 3;

[0037] The detection mechanism is connected to the frame 1 below the movable support panel 3, and the detection mechanism is turned on when the movable support panel 3 is close to the frame 1.

[0038] In actual use, when there is no silicon steel coil 8 on the silicon steel coil storage device, the movable support panel 3 is in a tilted state under the action of the elastic support body 6, and the detection mechanism is not connected; when there is a silicon steel coil 8 on the silicon steel coil storage device, the silicon steel coil 8 presses down the movable supporting panel 3, and contacts and connects with the detection mechanism, and then sends out information that there is a coil.

[0039] In specific applications, the two support panels connected to the upper surface of the frame 1 may be one movable support panel 3 and one fixed support panel 2, or both movable support panels. When multiple sets of elastic support bodies 6 are provided, the multiple sets of elastic support bodies 6 are fixed on the frame 1 under the movable support panels 3 at intervals, and the top of each set of elastic support bodies 6 is in contact with the movable support panel 3.

[0040] The detection mechanism in this embodiment can be installed at a position of the frame 1 where the detection mechanism can be connected when the movable support panel 3 is pressed down.

[0041] The technical solution adopted in the present invention can convert the information of whether there is a coil on the storage device into information of whether the movable support panel is pressed down, thereby providing support for the subsequent automatic unloading function of the coil from the winder, thereby greatly improving the automation and intelligence of the logistics warehousing of silicon steel coils.

[0044] In actual use, when the silicon steel coil 8 is placed on the frame 1, on the one hand, since the inner sides of the two rectangular plates are tilted inward and downward, the silicon steel coil 8 can be in safe and stable contact with the two rectangular plates and is not easy to roll off; on the other hand, due to the arrangement of multiple vertical plates 10, the strength of the frame 1 is guaranteed, greatly enhancing safety.

[0045] Embodiment three:

[0046] Reference Figure 1 and Figure 3 A silicon steel coil storage device with a material detection mechanism is shown, based on the second embodiment, each of the vertical plates 10 is a rectangular plate, and an isosceles triangle groove is arranged on the top; the two rectangular plates in the top plate 11 are respectively connected to the two sides of the isosceles triangle; a rectangular plate in the top plate 11 is connected to the detection mechanism, and a plurality of sets of elastic support bodies 6 are evenly and evenly connected, and the rectangular plate is connected to the movable support panel 3 through a connecting mechanism so that it can rotate or move up and down.

[0047] In actual use, the top of the vertical plate 10 adopts an isosceles triangle groove. When the silicon steel coil 8 is placed on the frame 1, the center of gravity of the silicon steel coil 8 can be completely placed on the center line of the frame 1, and rollover accidents are not likely to occur. Not only is the safety enhanced, but the silicon steel coil storage device is also not easily damaged. When the rectangular plate on which the detection mechanism is set is rotatably connected to the movable support panel 3, when there is no silicon steel coil 8 on the silicon steel coil storage device, under the action of the elastic support body 6, one side of the movable support panel 3 is connected to the connection mechanism, and the other side is tilted to ensure that the detection mechanism is not connected; when there is a silicon steel coil 8 on the silicon steel coil storage device, under the action of the silicon steel coil 8, the tilted side of the movable support panel 3 rotates downward around the connection mechanism until it is pressed down, so that it is connected to the detection mechanism set on the frame 1 and sends information. When the rectangular plate on which the detection mechanism is set is connected in a manner that it can be moved up and down with the movable support panel 3, when there is no silicon steel coil 8 on the silicon steel coil storage device, under the action of the elastic support body 6 and the connection mechanism, the movable support panel 3 is propped up and parallel to the top plate of the frame 1, ensuring that the detection mechanism is not connected; when there is silicon steel coil 8 on the silicon steel coil storage device, under the action of the silicon steel coil, the movable support panel 3 moves downward in a horizontal direction until it is pressed down, so that it is connected to the detection mechanism set on the frame 1 and sends out information.

[0048] Embodiment 4:

[0052] In actual use, a signal is sent only when the metal plate 7 is close to the proximity switch 5. In this solution, the metal plate 7 is connected to the movable support panel 3 accordingly, and the proximity switch 5 is triggered by tilting or pressing down the movable support panel 3, which is simple, convenient, and has a low implementation cost.

[0055] In actual use, the movable support panel 3 adopts a phenolic laminated plate. The phenolic laminated plate is an insulating material with suitable strength and rigidity. When it contacts the silicon steel coil 8, it will not damage the coil and will not generate metal debris, thereby avoiding the influence of metal debris generated during use due to the use of metal plates on the performance of the subsequent transformer core.

[0056] Embodiment six:

[0057] Reference Figure 1 and Figure 2 A silicon steel coil storage device with a material detection mechanism is shown. Based on the first or third embodiment, the elastic support body 6 includes a compression spring, a shell and a contact head; the shell is fixed to the lower surface of the frame 1; the compression spring is arranged in the shell; the bottom end of the compression spring contacts the bottom surface of the shell, and the top end of the compression spring is connected to the contact head, which extends to the upper surface of the movable support panel 3 and contacts the lower surface of the movable support panel 3.

[0058] In actual use, the function of the elastic support body 6 is that when there is no silicon steel coil 8 placed on the silicon steel coil storage device, the compression spring is in a free state, and the movable support panel 3 is tilted up under the support of the contact head, so that the metal plate 7 set on the movable support panel 3 cannot contact the proximity switch 5; when the silicon steel coil 8 is placed on the silicon steel coil storage device, the compression spring is compressed, and the movable support panel 3 is pressed down, so that the metal plate 7 set on the movable support panel 3 contacts the proximity switch 5, and the proximity switch 5 sends a signal.

[0059] The elastic support body 6 and the detection mechanism in this embodiment are arranged at different positions of the frame 1 under the movable support panel 3 .

[0060] The adoption of this technical solution can simply and conveniently realize the detection of whether there is silicon steel coil on the storage device and the sending of signals.

[0061] Embodiment seven:

[0063] In actual use, when the rectangular plate on which the detection mechanism is set is rotatably connected to the movable support panel 3 through the movable hinge 4, when there is no silicon steel coil 8 on the silicon steel coil storage device, one side of the movable support panel 3 is connected to the movable hinge 4, and under the action of the elastic support body 6, the other side is tilted up to ensure that the detection mechanism is not connected; when there is silicon steel coil 8 on the silicon steel coil storage device, under the action of the silicon steel coil 8, the tilted side of the movable support panel 3 rotates downward around the movable hinge 4 until it is pressed down, so that it is simply and conveniently connected to the detection mechanism set on the frame 1 and sends out information that there is a coil.

[0064] In specific applications, the elastic pin in the prior art can also be used to replace the elastic support body.

[0065] Embodiment eight:

[0066] A silicon steel coil storage device with a material detection mechanism. Based on the first embodiment, the connection mechanism includes a guide post and a guide sleeve; the guide post is connected to the movable support panel 3, the guide sleeve is connected to the frame 1, and the guide sleeve is sleeved on the guide post.

[0067] In actual use, a guide sleeve is provided on the rectangular plate where the detection mechanism is set, and a guide column is provided on the movable support panel 3. With the cooperation of the guide sleeve and the guide column, the frame 1 and the movable support panel 3 can be connected to move up and down. When there is no silicon steel coil 8 on the silicon steel coil storage device, the movable support panel 3 is spaced from the top plate of the frame 1 under the action of the elastic support body 6 and the guide column and sleeve structure, so as to ensure that the detection mechanism is not connected; when there is silicon steel coil 8 on the silicon steel coil storage device, under the action of the silicon steel coil 8, the movable support panel 3 moves downward until it is pressed down and is simply and conveniently connected to the detection mechanism set on the frame 1 and sends out information that there is a coil.

[0070] In actual use, the lower spring steel plate is fixed on the frame 1, and there is a certain distance between the lower spring steel plate and the proximity switch 5 connected to the frame 1. When the silicon steel coil 8 is not placed on the storage device, the spring steel plate is in an open state, and the upper spring steel plate is tilted, so that the upper spring steel plate cannot contact the proximity switch 5; when the silicon steel coil is placed on the storage device, the upper spring steel plate is pressed down, and finally the upper spring steel plate is close to the proximity switch 5 until it is connected, and the proximity switch 5 sends a signal.

[0071] The upper spring steel plate and the lower spring steel plate in this embodiment are arranged at an angle of 10-20°, which, on the one hand, avoids the angle being too small, causing the upper spring steel plate to accidentally contact the proximity switch 5 and send out an error message, and on the other hand, avoids the angle being too large, causing resistance when the silicon steel coil is placed on the rack 1 and causing an accident.

[0072] The movable support panel 3 and the elastic support body 6 are of an integrated structure, so that the structure of the present invention is simpler while ensuring that its functions can be achieved.
