[0043] During the process of placing the iron piece 81, first, the transport cylinder 11 drives the lifting cylinder 12 and the demagnetization cylinder 13 to move to the top of the storage plate 4. At this time, the demagnetization plate 3 is sleeved on the magnetic suction plate 2, and the lifting cylinder 12 and the demagnetization cylinder 13 respectively drive the demagnetization plate 3 and the magnetic suction plate 2 to move downward along the coaxial vertical direction, and the demagnetization plate 3 and the magnetic suction plate 2 move downward the same distance to ensure that the demagnetization plate 3 remains sleeved on the magnetic suction plate 2, and the demagnetization plate 3 and the magnetic suction plate 2 remain relatively still. The demagnetization plate 3 and the magnetic suction plate 2 move downward to the position of absorbing the iron piece 81 and then stop. After the magnetic suction plate 2 absorbs the iron piece 81, the lifting cylinder 12 and the demagnetization cylinder 13 respectively drive the demagnetization plate 3 and the magnetic suction plate 2 to move upward along the coaxial vertical direction. At this time, the demagnetization plate 3 and the magnetic suction plate 2 still remain relatively still, and then, The transport cylinder 11 drives the lifting cylinder 12 and the demagnetization cylinder 13 to move to the top of the fixture 5, then, the lifting cylinder 12 and the demagnetization cylinder 13 respectively drive the demagnetization plate 3 and the magnetic plate 2 to move downward along the coaxial vertical direction, the demagnetization plate 3 and the magnetic plate 2 move downward the same distance, and the iron piece 81 is placed on the magnetic assembly 82 on the fixture 5, then, the demagnetization cylinder 13 drives the magnetic plate 2 to move upward in the vertical direction, the magnetic plate 2 no longer generates suction on the iron piece 81, the lifting cylinder 12 and the demagnetization plate 3 remain stationary, the demagnetization plate 3 is evenly pressed on the iron piece 81, the iron piece 81 is accurately and steadily placed on the top of the magnetic assembly 82, the iron piece 81 is placed, and the automated placement of the iron piece 81 greatly reduces the workload of the workers, and also significantly improves the production efficiency of the product.

[0044] As a preferred solution, the magnetic attraction plate 2 is provided with a connecting protrusion 21, and the demagnetization plate 3 is provided with a connecting groove 31, and the connecting groove 31 is sleeved on the connecting protrusion 21. The connecting groove 31 reduces the thickness of the demagnetization plate 3, and the magnetic attraction plate 2 is closer to the iron piece 81, making it easier for the magnetic attraction plate 2 to attract the iron piece 81. Furthermore, the top surface shape of the connecting protrusion 21 and the bottom surface shape of the connecting groove 31 are the same as the shape of the iron piece 81. The magnetic attraction plate 2 can not only apply force to the iron piece 81 more evenly, but also improve the stability of attracting the iron piece 81, thereby ensuring that the placement position of the iron piece 81 is accurate and improving product quality.

[0045] In addition to the magnetic attraction method, there are many other ways for the magnetic attraction plate 2 to attract the iron piece 81, which are not limited here. As a preferred embodiment, a groove 23 is provided at the bottom of the connecting protrusion 21, and a magnet with a polarity opposite to the magnetic component 82 placed on the fixture 5 is installed in the groove 23. The magnet attracts the iron piece 81 and does not repel the magnetic component 82. In addition to placing the magnet, the magnetic attraction plate 2 can also be energized so that the magnetic attraction plate 2 has a magnetic property with a polarity opposite to that of the magnetic component 82, and then attracts the iron piece 81. The method for the magnetic attraction plate 2 to generate magnetic force is also not limited here.

[0046] As a preferred solution, a reset device 7 is also included. The top surface of the workbench 6 is provided with the reset device 7. The material storage plate 4 and the fixture 5 are installed on the reset device 7. The reset device 7 is used to reset the material storage plate 4 and the fixture 5 to a position where the two are parallel. Since placing the iron piece 81 on the top of the magnetic assembly 82 is only a procedure in the processing of the Halbach magnetic assembly 8, there may be other devices before and after the device for placing the iron piece 81 of the Halbach magnetic assembly 8. In order to connect the processing flow before and after, the initial positions of the material storage plate 4 and the fixture 5 may not be parallel. The workbench 6 is provided with a reset device 7 to reset the material storage plate 4 and the fixture 5 to a position where the two are parallel, so as to facilitate the mobile device 1 to transfer the iron piece 81, and transfer the iron piece 81 from the material storage plate 4 to the top of the magnetic assembly 82 on the fixture 5.

[0047] As a preferred solution, the reset device 7 includes a rotary cylinder 71 and a feeding cylinder 72. The rotary cylinder 71 drives the material storage plate 4 to rotate in the plane of the reset device 7, and the feeding cylinder 72 drives the fixture 5 to move laterally in the plane of the reset device 7. The rotary cylinder 71 drives the material storage plate 4 to rotate at any angle in the plane, and the feeding cylinder 72 drives the fixture 5 to move laterally in the plane. Regardless of the initial positions of the material storage plate 4 and the fixture 5, the material storage plate 4 rotates through the rotary cylinder 71, and the fixture 5 moves laterally through the feeding cylinder 72. The material storage plate 4 and the fixture 5 must be in a parallel state. Rotation and lateral translation are only a preferred reset motion mode, which is not limited here.

[0048] As a preferred solution, the magnetic attraction plate 2 is provided with a plurality of connection protrusions 21, and the demagnetization plate 3 is provided with a plurality of connection grooves 31 sleeved with the plurality of connection protrusions 21. The storage plate 4 is provided with a plurality of card slots 41 corresponding to the plurality of connection protrusions 21 one by one, and the card slots 41 are used to place iron pieces 81. The device can carry multiple iron pieces 81 at the same time, thereby improving production efficiency.

[0049] The slot 41 is provided with a hole 42, and a magnet is provided in the hole 42. The iron piece 81 is placed in the slot 41, and the magnet attracts the iron piece 81. On the one hand, it is ensured that the iron piece 81 is less difficult to operate during the placement process, and the iron piece 81 is sucked into the slot 41 under the action of the magnet during the placement. On the other hand, it is ensured that during the transportation process of the iron piece 81, the iron piece 81 added in the slot 41 will not have the risk of falling due to the vibration and inertia of the device.

[0050] As a preferred solution, it also includes a buffer structure 9, which includes a fixed plate 91, a spring 92 and a linear guide rail 93. The fixed plate 93 is fixedly connected to the lifting cylinder 12. A protrusion 911 is provided on the fixed plate 91, and a linear guide rail 93 is provided under the protrusion 911. The linear guide rail 93 slides in the vertical direction of the plane of the fixed plate 91. The spring 92 is clamped between the protrusion 911 and the linear guide rail 93, and the demagnetization plate 3 is fixedly connected to the linear guide rail. The lifting cylinder 12 and the demagnetization cylinder 13 respectively drive the demagnetization plate 3 and the magnetic attraction plate 2 to move downward along the coaxial vertical direction. The demagnetization plate 3 is subjected to a vertical upward supporting force at the moment it contacts the iron piece 81. Under the action of the supporting force, the demagnetization plate 3 drives the linear guide rail 93 to slide upward a short distance, and the spring 92 between the linear guide rail 93 and the fixed plate 91 is compressed. Under the dual action of the linear guide rail 93 and the spring 92, the supporting force of the iron piece 81 is slowly released, thereby preventing the demagnetization plate 3 from pressing the iron piece 81 hard and damaging the iron piece 81 or the magnetic component 82.

[0051] The above description is only a preferred embodiment of the present utility model and is not a limitation on the design of the present case. Any equivalent changes made based on the key design of the present case shall fall within the protection scope of the present case.
