Description

Technical Field

[0001] This invention relates to the field of charging and demagnetizing equipment technology, specifically to an intelligent charging and demagnetizing device for nano-two-phase magnetic materials. Background Technology

[0002] Magnetization is the process of magnetizing magnetic materials or increasing the magnetism of a magnet that is not magnetic enough. Generally, the magnetizable object is placed in the magnetic field formed by a coil through which a direct current passes. Demagnetization, also known as magnetic cleaning or demagnetization, refers to the process of restoring a magnet to a magnetically neutral state. In industry, demagnetization is commonly achieved by three methods: static, dynamic, and thermal. 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 CN104465019A discloses an intelligent charging and demagnetizing device for nano-two-phase magnetic materials. It uses a constant DC magnetic field for charging and an AC commutation demagnetizing method for demagnetizing. The device detects the residual magnetism on the surface of the material through a magnetic field detector and transmits the data to the detection and control system, thereby realizing the intelligent switching between AC demagnetization and DC excitation functions for the two-phase magnetic material. Finally, based on the zero-crossing detection circuit, it realizes the charging and demagnetizing of the two-phase magnetic material at the zero point. The intelligent charging and demagnetizing device for nano-two-phase magnetic materials provided by this patent does not take into account the high temperature caused by the long-term energization of the coil. In some highly automated production lines, the long-term high temperature of the coil will affect the physical properties of the coil and the charging and demagnetizing effect, thereby reducing the charging and demagnetizing efficiency of the device.

[0012] This invention provides an intelligent charging and demagnetizing device for nano-two-phase magnetic materials. It has the following beneficial effects: 1. This intelligent charging and demagnetizing device for nano-two-phase magnetic materials, by setting up a pre-measuring mechanism, uses a Hall sensor array to detect the magnetic field strength of the object to be charged or demagnetized. By using the Hall sensor array in conjunction with the charging and demagnetizing mechanism, the magnetic field strength applied to the object is precisely controlled by adjusting the magnitude of the current and the position of the coil.

[0013] 2.

[0018] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments.

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

[0020] Please see Figure 1-2 The present invention provides a technical solution: an intelligent charging and demagnetizing device for nano-two-phase magnetic materials, including a conveyor body 1, an electrical control cabinet 2, an isolation box 4, and a charging and demagnetizing mechanism 5. A conveyor belt is rotatably connected to the top of the conveyor body 1, and a DC motor is fixedly connected to the left side of the conveyor body 1. The DC motor of the conveyor body 1 is rotatably connected to the transmission belt through rollers, and a servo motor is electrically connected to the electrical control cabinet 2 through wires. A front measuring mechanism 3 is fixedly connected to the top of the conveyor body 1. The front measuring mechanism 3 includes a laser rangefinder 31, which is fixedly connected to the front of the conveyor body 1. A Hall sensor array 32 is fixedly connected to the top of the conveyor body 1, located on the front of the molded housing 41. Both the laser rangefinder 31 and the Hall sensor array 32 are electrically connected to the electrical control cabinet 2 via wires. The isolation box 4 includes a molded shell 41, which is fixedly connected to the top of the conveyor body 1. A temperature sensor is embedded inside the molded shell 41. A semiconductor cooler 42 is fixedly connected to the top of the molded shell 41. The cooling end of the semiconductor cooler 42 is located inside the molded shell 41. An air inlet plate 43 is connected to the front of the molded shell 41. A blower is connected to the front of the air inlet plate 43. The semiconductor cooler 42 and the air inlet plate 43 are both electrically connected to the electrical 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 bidirectional cooling mechanism 6.

[0021] During use, before starting the device, the object to be magnetized or demagnetized is placed on the conveyor belt of the conveyor platform 1. Then, the device is started through the electrical control cabinet 2. The conveyor belt of the conveyor platform 1 moves the object backward. During this process, the laser rangefinder 31 monitors the distance between the object and the laser rangefinder 31 in real time to determine the object's position. When the object passes the bottom of the Hall sensor array 32, the Hall sensor array 32 transmits the detected magnetic field strength data of the object back to the electrical control cabinet 2. When the object moves to the vicinity of the isolation box 4, the electrical control cabinet 2 controls the magnetization or demagnetization mechanism 5 to magnetize or demagnetize. During this process, the semiconductor cooler 42 and the air inlet plate 43 are started under the control of the electrical control cabinet 2. The air inlet plate 43 draws cold air from the outside into the molded shell 41. After the cold air enters the molded shell 41, it absorbs the heat generated by the C-shaped coil group 51. At the same time, the cooling end of the semiconductor cooler 42 cools the air inside the molded shell 41 that has absorbed heat, thereby maintaining the temperature inside the molded shell 41 within the normal range. Example 2

[0022] Please see Figure 1-6 Based on Embodiment 1, the present invention provides a technical solution: the charging / demagnetizing mechanism 5 includes: C-shaped coil assembly 51, including hollow iron core 511, hollow iron core 511 has a hollow C-shaped cross-section, hollow iron core 511 is filled with coolant, and hollow iron core 511 is rotatably connected to the inside of plastic shell 41. The coupling sleeve 52 is fixedly connected to the left side of the hollow iron core 511; The control motor 53 is fixedly connected to the left side of the plastic housing 41. 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 electrical control cabinet 2 through wires. The radiator box 54 is connected to the right side of the hollow iron core 511. The radiator 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 plate 542 is inserted inside the box body 541. The heat dissipation plate 542 is made of copper alloy. A rectangular through hole is opened on the top of the heat dissipation plate 542. The bottom of the box body 541 is connected to the top of the circulation pump 55 through a metal pipe. The circulating pump 55 is connected to the right side of the hollow iron core 511. The top of the circulating pump 55 is connected to the bottom of the dispersing box 54. The circulating pump 55 is electrically connected to the electrical control cabinet 2 through a wire.

[0023] In use, in Example 1, when the object moves to the vicinity of the isolation box 4, the control motor 53 rotates under the control of the electrical control cabinet 2. At the same time, the electrical control cabinet 2, in conjunction with the magnetic field strength data fed back by the Hall sensor array 32, supplies a corresponding DC current to the coil group 512. If it is a magnetization process, the connecting sleeve 52 controls the hollow iron core 511 to gradually adjust the relative angle between the hollow iron core 511 and the object surface to maintain the relative stability of the positional relationship between the coil group 512 and the object surface, thereby realizing the magnetization process. If it is a demagnetization process, the electrical control cabinet 2, in conjunction with the feedback data from the Hall sensor array 32, supplies a corresponding DC current to the coil group 512 while controlling the connecting sleeve 52 to rotate at a certain speed and direction at a uniform speed, thereby forming an alternating magnetic field with periodically changing direction, thereby realizing the demagnetization of the object. During the charging and demagnetizing process, the circulating pump 55 is started under the control of the electrical 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 541, transferring the heat to the heat dissipation plate 542, which then dissipates the heat to the inside of the bidirectional cooling mechanism 6. After dissipating the heat, the coolant is discharged back into the circulating pump 55 for subsequent circulation. Example 3

[0024] Please see Figure 1-8Based on Embodiment 1 and Embodiment 2, the present invention provides a technical solution: the bidirectional cooling mechanism 6 includes a diffuser 61, the diffuser 61 has a rectangular through hole on its front side, the diffuser 61 is fixedly connected to the right side of the plastic shell 41 on its left side, the plastic shell 41 is rotatably connected to an exhaust shaft ring 62 on its right side, 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 plastic shell 41, an iron core fixing plate 622 is fixedly connected inside the outer shaft ring 621, the iron core fixing plate 622 is fixedly connected to the outer surface of the right side of the hollow iron core 511, rectangular blades 623 are fixedly connected to both the front and back sides of the iron core fixing plate 622, an eccentric plate is fixedly connected to the right side of the iron core fixing plate 622, and the eccentric plate is fixedly connected to the metal tube at the bottom of the box 541; An air intake fan 63 is fixedly connected to the right side of the eccentric tube of the iron core fixing plate 622. The air intake fan 63 is made of polymer, and the deflection angle of the blades on the surface of the air intake fan 63 is opposite to that of the rectangular blades 623.

[0025] In use, during the process of Embodiment 1, the exhaust shaft ring 62 and the hollow iron core 511 rotate together. During the rotation, the rectangular blades 623 draw the air inside the plastic shell 41 into the diffuser 61. At the same time, the intake fan 63 and the exhaust shaft ring 62 rotate together, drawing in external cold air into the diffuser 61. Since the eccentric plate also rotates together, it promotes the mixing of the hot air drawn out of the plastic shell 41 with the cold air drawn in by the intake fan 63. The mixed air absorbs the heat dissipation plate 542 and, under the combined action of the rotation of the eccentric plate and the increased flowability of the gas after heat absorption, the hot air is discharged from the through hole of the diffuser 61, thereby carrying away excess heat.

[0026] The above description is only a preferred embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in the present invention, based on the technical solution and inventive concept of the present invention, should be covered within the scope of protection of the present invention.
