Description

Technical Field

[0001] This application relates to the field of degaussing technology, and particularly to an automated degaussing tooling device and system. Background Art

[0002] The degaussing process means that magnetized materials are affected by external energy such as heating and impact, and the magnetic moment directions of the magnetic domains therein become inconsistent, and the magnetism will weaken or disappear. Commonly used degaussing methods include thermal demagnetization, alternating current demagnetization, etc. The so-called alternating current demagnetization means that the workpiece to be degaussed is placed in an alternating current magnetic field, and the intensity of the alternating current magnetic field is gradually weakened until it disappears, and the workpiece material is then degaussed.

[0003] Existing degaussing devices achieve degaussing by manually moving the workpiece to be degaussed or changing the induction distance between the main and secondary coil electromagnets, so that the induced current gradually decreases until the induced current is zero. This manually operated degaussing method has many uncontrollable factors. For example, different operators have different operation methods due to factors such as movement speed and movement trajectory, and it is difficult for the same operator to achieve consistent degaussing effects at different times. Therefore, the controllability of the degaussing effect in the whole process is poor, and it is difficult to ensure the stability and consistency of degaussing, etc.

[0004] Therefore, for R & D personnel in this field, it is urgent to develop an automated degaussing tooling device and system with better degaussing effect. Utility Model Content

[0040] Refer to Figure 1 As shown, this embodiment provides an automated degaussing tooling device, which includes a tooling main body 1, a degaussing unit 2, a control unit 3, and a driving unit 4; the tooling main body 1 includes a tooling base 12 and a vertical guide rail 11 vertically fixed to the tooling base 12; the degaussing unit 2 includes a main coil 21 and an auxiliary coil 22 adapted to the main coil, and the auxiliary coil 22 moves along the vertical guide rail 11, and the movement includes up and down sliding and rotational movement along a vertical plane parallel to the vertical guide rail; Combined Figure 4 As shown, the auxiliary coil 22 is connected to the degaussing coil 5 of the workpiece 6 to be degaussed; the control unit 3 is connected to the driving unit 4 and is used to output a control signal to the driving unit 4 according to the optimal degaussing current change curve of the workpiece 6 to be degaussed, and the driving unit 4 is used to drive the movement of the auxiliary coil 22 on the tooling main body 1 according to the control signal.

[0041] It should be noted that, combined Figure 5 、 Figure 6 As shown, the optimal degaussing current change curve of the workpiece 6 to be degaussed in this embodiment is calculated based on the self-attributes of the workpiece to be degaussed, and the optimal current change curve of the workpiece to be degaussed is collected by the acquisition module 31 of the control unit 3; the calculation module 32 of the control unit 3 adjusts the current size in real time by controlling the relative distance between the main and auxiliary coils according to the optimal current change curve and the self-attributes of the main and auxiliary coils, and finally generates a current change curve consistent with the optimal degaussing current curve of the workpiece 6 to be degaussed. The movement trajectory and movement speed of the auxiliary coil are calculated according to this current change curve, and the movement trajectory curve and movement speed information are preset into the computer software, and the corresponding movement control instructions are sent to the stepping motor of the driving unit 4 through the control module, and the movement curve is adjusted and the acceleration and deceleration are controlled by calculating the real-time position information of the auxiliary coil, so as to complete the control of the movement of the auxiliary coil and achieve an automated closed-loop control to achieve the best degaussing effect.

[0042] As Figure 1 shown, a slider 13 is provided on the vertical guide rail 11 of the tooling main body 1, a suspension shaft for hanging the auxiliary coil 22 extends horizontally from the slider 13, and a rotating structure 14 is provided on the suspension shaft. The rotating structure 14 is connected to the auxiliary coil. After the main and auxiliary coils are separated by a certain distance, the axis of the auxiliary coil is rotated 90 degrees through the rotating structure to reduce the mutual inductance between the coils. This direction is perpendicular to the plane formed by XY, so that the induced current gradually tends to zero, and finally the degaussing effect is achieved. Further, upper limit members 15 and lower limit members 16 are respectively provided at both ends of the vertical guide rail 11 to avoid problems such as tripping and collision, and enhance the use stability of this tooling device.

[0043] As a preferred embodiment, the main coil 21 can be separately fixed beside the tooling main body 1, and the separation or overlapping cooperation between the secondary coil and the main coil is realized by the forward and reverse rotation of the stepping motor of the driving unit.

[0044] Using the technical solution of this embodiment, briefly describe the principle of demagnetization of the automatic demagnetization tooling device in this embodiment as follows:

[0045] First, connect the secondary coil 22 of the demagnetization unit to the demagnetization coil 5 of the workpiece 6 to be demagnetized, and apply alternating current to the automatic demagnetization tooling device. After the secondary coil 22 is initially located within the main coil 21 for 10 - 20 seconds, at this time, an induced current is generated in the secondary coil 22 and transmitted to the demagnetization coil 5 wound around the workpiece to be demagnetized. At this time, a relatively large magnetic field is generated in the demagnetization coil 5, making the magnetism of the workpiece 6 to be demagnetized reach saturation; then, the control unit 3 outputs a control signal according to the optimal demagnetization current change curve of the workpiece 6 to be demagnetized to control the movement of the stepping motor of the driving unit 4, and procedurally drives the secondary coil 22 to move upward along the vertical guide rail 11 of the tooling main body 1, so that a relative position change relationship is formed between the secondary coil 22 and the main coil 21, thereby generating a changing mutual inductance current in the secondary coil 22. After the main and secondary coils are separated by a certain distance, the axis of the secondary coil can be further rotated by 90 degrees through the rotating structure 14 to make the induced current gradually tend to zero, achieving a demagnetization effect of final stable control, and having the technical effects of strong demagnetization stability, consistency, and controllability.

[0046] As another embodiment, as Figure 2 shown, to better achieve the demagnetization effect of the tooling device and at the same time make the device have the advantage of more convenient use, a plurality of moving wheels 120 are symmetrically arranged at the bottom of the tooling base 12. By horizontally pushing the device, the movement of the moving wheels also facilitates the secondary coil to move a certain distance away from the main coil in the horizontal direction, further ensuring the thoroughness of the demagnetization effect. Of course, the mechanical control movement can also be realized by applying the power of the driving unit to the moving wheels.

[0047] As another embodiment, as Figure 3 shown, to achieve a better demagnetization effect, a horizontal guide rail can be further provided on the tooling base 12, and a connecting block 19 adapted to the horizontal guide rail is provided at one end of the vertical guide rail 11 close to the tooling base. Further, front limit members 17 and rear limit members 18 are respectively provided at both ends of the horizontal guide rail to avoid problems such as lateral disengagement and collision, and enhance the use stability of the tooling device.

[0048] As another embodiment, on the other hand, the embodiment of the present application provides an automatic demagnetization system, which includes a demagnetization coil and a workpiece to be demagnetized, and also includes the automatic demagnetization tooling device described in any of the above embodiments.
