[0025] An embodiment of the present invention discloses an automatic connection device for a multifunctional electromagnet.

[0026] Embodiment 1

[0027] The present invention provides an automatic connection device for a multifunctional electromagnet as shown in Figures 1-3 Figure, which includes an electromagnet 1 and a support block 2 fixedly arranged on the top of the electromagnet 1. A plurality of connecting plates 3 arranged in a circumferentially symmetric manner are provided on the outer wall of the support block 2. A cross bar 4 is fixedly arranged inside the connecting plate 3. A positioning rod 5 is rotatably sleeved on the rod wall of the cross bar 4. A torsion spring 10 is sleeved on the rod wall of the cross bar 4. Two ends of the torsion spring 10 are respectively fixedly connected with the cross bar 4 and the positioning rod 5. An adjusting component is arranged on the rod wall of the positioning rod 5;

[0028] An upper end of the outer wall of the support block 2 is provided with a groove. A motor 6 is fixedly arranged on the inner wall of the groove. A driving groove is provided at a lower end outside the support block 2. A driving screw 7 is rotatably arranged inside the driving groove. An output shaft of the motor 6 penetrates into the driving groove and is fixedly connected with the driving screw 7. A slide plate 8 is threadedly sleeved on the rod wall of the driving screw 7. One end of the slide plate 8 is slidably arranged inside the driving groove. The other end of the slide plate 8 is fixedly sleeved with a ring plate 9. The ring plate 9 covers the outside of a plurality of positioning rods 5.

[0029] Before the electromagnet adsorbs and transfers materials, the electromagnet 1 moves to the surface of the materials and contacts the materials. Subsequently, the motor 6 is started, so that the driving screw 7 rotates to drive the slide plate 8 to slide inside the operation groove, so that the slide plate 8 drives the ring plate 9 to move downward. During the movement of the ring plate 9, the ring plate 9 pushes a plurality of positioning rods 5, so that the positioning rods 5 rotate along the cross bar 4 to twist the torsion spring 10. At this time, the plurality of positioning rods 5 rotate simultaneously to push the materials, so that the electromagnet 1 can move to the center of the materials during the movement of the materials. Then the electromagnet 1 is started to adsorb the materials, thereby completing the connection between the electromagnet 1 and the materials.

[0030] Embodiment 2

[0031] Example 2 On the basis of Example 1, in order to be able to adjust the pushing length of the positioning rod 5 according to the size of the material, as Figure 1 shown, the adjusting assembly includes a sleeve 11. A thread 16 is provided on the rod wall of the positioning rod 5. The sleeve 11 is threadedly sleeved on the outside of the positioning rod 5, and the sleeve 11 is an internally threaded tube.

[0032] Before adsorbing the material, the sleeve 11 can be rotated so that the sleeve 11 rotates forward along the positioning rod 5, thereby increasing the pushing range of the positioning rod 5.

[0033] Example 3

[0034] Example 3 On the basis of Example 1, in order to be able to control the operation of the motor 6 after the electromagnet 1 contacts the material, as Figures 1-2 shown, a groove is provided at the bottom of the electromagnet 1. A first contact piece 12 is slidably provided on the inner wall of the groove. A second contact piece 13 is fixedly provided at the top of the inner wall of the groove. Two symmetrically arranged springs 14 are fixedly provided between the first contact piece 12 and the second contact piece 13. The first contact piece 12 and the second contact piece 13 are cooperatively arranged. A controller 15 is fixedly provided at the upper end of the outer wall of the support block 2. The controller 15 is cooperatively arranged with the second contact piece 13 and the motor 6.

[0035] When the electromagnet 1 moves to the surface of the material and contacts the material, the first contact piece 12 is squeezed by the material to squeeze the spring 14. At this time, the first contact piece 12 contacts the second contact piece 13. Subsequently, the controller 15 receives the contact signal between the first contact piece 12 and the second contact piece 13 and controls the motor 6 to start. Subsequently, the motor 6 operates so that the annular plate 9 is stably driven, and a plurality of positioning rods 5 are pushed to complete the pushing of the material.

[0036] Only some exemplary embodiments of the present invention have been described by way of illustration above. Undoubtedly, for those of ordinary skill in the art, without departing from the spirit and scope of the present invention, the described embodiments can be modified in various different ways. Therefore, the above drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
