Description

Technical Field

[0001] The present invention relates to the technical field of charging and demagnetizing equipment, in particular to an intelligent charging and demagnetizing device for nano two-phase magnetic materials. Background Art

[0002] Magnetization is the process of magnetizing a magnetic material or increasing the magnetism of a magnet with insufficient magnetism. Generally, the magnetic object to be magnetized is placed in a magnetic field formed by a coil with direct current passing through it. Demagnetization, also known as magnetic cleaning or demagnetization, refers to the process of restoring a magnet to a neutral state. Static, dynamic, and thermal demagnetization are commonly used in industry to achieve demagnetization. Magnetic nanomaterials are a type of magnetic material with broad application prospects in the fields of mechanics, electronics, optics, magnetism, chemistry, and biology. Patent application publication number CN104465019A discloses an intelligent charging and demagnetization device for nano two-phase magnetic materials. The device uses a steady DC magnetic field for magnetization and an AC commutation demagnetization method for demagnetization. The device detects the surface remanence of the material using a magnetic field detector and transmits it to a detection and control system, achieving intelligent conversion between AC demagnetization and DC excitation functions for the two-phase magnetic material. Finally, based on a zero-crossing detection circuit, the device achieves charging and demagnetization of the two-phase magnetic material at zero time. The intelligent charging and demagnetization device for nano two-phase magnetic materials provided by this patent does not take into account the high temperature caused by long-term power supply to the coil. In some production lines with a high degree of automation, the long-term high temperature state of the coil will affect the physical properties and charging and demagnetization effect of the coil, thereby reducing the charging and demagnetization efficiency of the device.

[0018] The technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

[0019] Examples of the embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements having the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are intended to be used to explain the present invention, but are not to be construed as limiting the present invention. Example 1

[0020] See also Figure 1-2 The present invention provides a technical solution: an intelligent charging and demagnetization device for nano two-phase magnetic materials, comprising a conveyor body 1, an electric control cabinet 2, an isolation box 4, and a charging and demagnetization mechanism 5. The top of the conveyor body 1 is rotatably connected to a conveyor belt, and the left side of the conveyor body 1 is fixedly connected to a DC motor. The DC motor of the conveyor body 1 is rotatably connected to the transmission belt through a roller, and the servo motor is electrically connected to the electric control cabinet 2 through a wire. The top of the conveying platform 1 is fixedly connected to a front detection mechanism 3, which includes a laser ranging sensor 31. The laser ranging sensor 31 is fixedly connected to the front of the conveying platform 1. The top of the conveying platform 1 is fixedly connected to a Hall sensor array 32. The Hall sensor array 32 is located on the front of the plastic shell 41. The laser ranging sensor 31 and the Hall sensor array 32 are electrically connected to the electric control cabinet 2 through wires. The isolation box 4 includes a plastic shell 41, which is fixedly connected to the top of the conveying platform 1. A temperature sensor is embedded in the plastic shell 41. A semiconductor refrigerator 42 is fixedly connected to the top of the plastic shell 41. The cooling end of the semiconductor refrigerator 42 is located inside the plastic shell 41. The front of the plastic shell 41 is connected to an air inlet plate 43, and the front of the air inlet plate 43 is connected to a blower. The semiconductor refrigerator 42 and the air inlet plate 43 are electrically connected to the electric control cabinet 2 through wires. The charging and demagnetizing mechanism 5 includes a C-shaped coil group 51 , and the right side of the isolation box 4 is connected to a two-way cooling mechanism 6 .

[0021] During use, before the device is started, the object to be magnetized or demagnetized is placed on the conveyor belt of the conveying platform 1, and then the device is started through the electric control cabinet 2. The conveyor belt of the conveying platform 1 drives the object to move backward. During this process, the laser ranging sensor 31 monitors the distance from the object to the laser ranging sensor 31 in real time and then determines the position of the object. When the object passes the bottom of the Hall sensor array 32, the Hall sensor array 32 transmits the detected object magnetic field strength data back to the electric control cabinet 2. When the object moves near the isolation box 4, the electric control cabinet 2 controls the charging and demagnetization mechanism 5 to magnetize or demagnetize. During this process, the semiconductor refrigerator 42 and the air inlet plate 43 are started under the control of the electric control cabinet 2. The air inlet plate 43 draws cold air from the outside into the plastic shell 41. After the cold air from the outside enters the plastic shell 41, it absorbs the heat generated by the C-shaped coil group 51 when it is energized and heated. At the same time, the cooling end of the semiconductor refrigerator 42 cools the air that absorbs heat inside the plastic shell 41, thereby maintaining the temperature inside the plastic shell 41 stable within a normal range. Example 2

[0022] See also Figure 1-6 Based on the first embodiment, the present invention provides a technical solution: the charging and demagnetizing mechanism 5 includes: The C-shaped coil assembly 51 includes a hollow iron core 511 having a hollow C-shaped cross section. The hollow iron core 511 is filled with coolant and is rotatably connected to the interior of the plastic housing 41. The coupling sleeve 52 is fixedly connected to the left side of the hollow core 511; The control motor 53 is fixedly connected to the left side of the plastic housing 41, and the motor shaft of the control motor 53 is fixedly connected to the left side of the coupling sleeve 52. The control motor 53 is electrically connected to the electric control cabinet 2 through a wire; The dispensing box 54 is connected to the right side of the hollow iron core 511. The dispensing box 54 includes a box body 541. The left side of the box body 541 is connected to the right side of the hollow iron core 511. A heat dissipation hole plate 542 is inserted into the box body 541. The heat dissipation hole plate 542 is made of copper alloy and has a rectangular through hole on the top. The bottom of the box body 541 is connected to the top of the circulation pump 55 through a metal pipe. The circulation pump 55 is connected to the right side of the hollow iron core 511 , the top of the circulation pump 55 is connected to the bottom of the distribution box 54 , and the circulation pump 55 is electrically connected to the electric control cabinet 2 through a wire.

[0023] During use, in Example 1, when the object moves near the isolation box 4, the control motor 53 rotates under the control of the electric control cabinet 2. At the same time, the electric control cabinet 2 combines the magnetic field strength data fed back by the Hall sensor array 32 to pass the corresponding DC current to the coil group 512. If the magnetization process is being carried out, the coupling sleeve 52 controls the hollow iron core 511 to gradually adjust the relative angle between the hollow iron core 511 and the surface of the object to maintain the relative stability of the positional relationship between the coil group 512 and the surface of the object, thereby realizing the magnetization process. If the demagnetization process is being carried out, the electric control cabinet 2 combines the feedback data of the Hall sensor array 32 to pass the corresponding DC current to the coil group 512, and controls the coupling sleeve 52 to rotate at a certain speed and direction at a uniform speed, thereby forming an alternating magnetic field with periodic changes in direction, thereby realizing the demagnetization of the object. During the charging and demagnetization process, the circulating pump 55 is started under the control of the electric control cabinet 2, so that the coolant inside the hollow iron core 511 can circulate. The coolant absorbs part of the heat transferred by the coil group 512 and circulates to the inside of the box body 541, and transfers the heat to the heat dissipation hole plate 542. The heat dissipation hole plate 542 dissipates the heat to the inside of the two-way cooling mechanism 6. After the heat is dissipated, the coolant is discharged into the circulating pump 55 again for subsequent circulation. Example 3

[0024] See also Figure 1-8, on the basis of embodiment 1 and embodiment 2, the present invention provides a technical solution: the bidirectional cooling mechanism 6 includes an air dispersion pipe 61, the front of the air dispersion pipe 61 is connected with a rectangular through hole, the left side of the air dispersion pipe 61 is fixedly connected to the right side of the shaping shell 41, and the right side of the shaping shell 41 is rotatably connected with an exhaust shaft ring 62, the exhaust shaft ring 62 is made of copper alloy, the exhaust shaft ring 62 includes an outer shaft ring 621, the outer shaft ring 621 is rotatably connected to the right side of the shaping shell 41, the outer shaft ring 621 is fixedly connected to an iron core fixing plate 622, the inner part of the iron core fixing plate 622 is fixedly connected to the outer surface of the right side of the hollow iron core 511, the front and back sides of the iron core fixing plate 622 are fixedly connected to rectangular blades 623, the right side of the iron core fixing plate 622 is fixedly connected to an eccentric plate, and the eccentric plate is fixedly connected to the metal tube at the bottom of the box body 541; The right side of the eccentric tube of the core fixing plate 622 is fixedly connected with an air suction fan 63 . The air suction fan 63 is made of polymer, and the deflection angle of the blades on the surface of the air suction fan 63 is opposite to that of the rectangular blades 623 .

[0025] During use, in the process of Example 1, the exhaust shaft ring 62 rotates together with the hollow iron core 511, and the rectangular blades 623 suck the air inside the shaping shell 41 into the air duct 61 during the rotation. At the same time, the air intake fan 63 rotates together with the exhaust shaft ring 62, and the external cold air is sucked into the air duct 61. Since the eccentric plate also rotates together, the hot air sucked out of the shaping shell 41 and the cold air sucked in by the air intake fan 63 are mixed. The mixed air absorbs the heat emitted by the heat dissipation hole plate 542 at the same time, and the hot air is discharged from the through hole of the air duct 61 under the combined action of the rotation of the eccentric plate and the increased fluidity of the gas after absorbing heat, thereby taking away excess heat.

Any technician familiar with the technical field, within the technical scope disclosed by the present invention, who makes equivalent replacements or changes based on the technical solution and inventive concept of the present invention, should be covered by the scope of protection of the present invention.
