Description

Technical Field

[0001] The present invention relates to the technical field of magnetizing equipment, and in particular to a magnetizing system and a magnetizing method thereof. Background Art

[0002] Magnetic materials are widely used in motors, instruments, audio equipment, magnetic machinery and other fields. Before magnetic materials are assembled into devices with certain functions, they need to be magnetized in a magnetizer to have magnetism.

[0003] When magnetizing in the prior art magnetizer, the magnetic material to be magnetized is first placed into the magnetizing hole of the magnetizer, and then magnetization is started. Although the device can make the magnetic material magnetic, the design of the structure needs to facilitate the frequent placement and removal of the magnetic material in the magnetizing hole, so there is a gap between the magnetic material and the magnetizing hole. In addition, the shape and position tolerances and dimensional tolerances between the surfaces of the magnetic material and the inner wall of the magnetizing hole cannot be eliminated, which ultimately leads to uneven magnetization effects of the same magnetizing hole on the same workpiece. According to tests, the extreme difference in magnetic flux density at different sections of the same workpiece after magnetization will be more than 30mt.

[0004] See patent documents: (CN203070866U-a magnetizing machine, CN213459286U-a radial magnetizing system, CN205829410U-a permanent magnet rotor low harmonic magnetizing device).

[0005] Therefore, in order to solve the problem of uneven magnetization effect of traditional magnetizers, a new magnetization system is needed. Summary of the invention

[0006] The object of the present invention is to provide a magnetizing system and a magnetizing method thereof, which have the characteristics of uniform magnetizing effect.

[0007] To achieve the above object, the present invention provides the following technical solutions: The present invention provides a magnetizing system, including a magnetizing core and an electromagnetic coil, and also provided with a driving mechanism, wherein the magnetizing core includes a winding cavity for arranging the electromagnetic coil, and two magnetizing heads arranged at intervals for magnetizing an object to be magnetized, the electromagnetic coil is wound around the magnetizing core located in the winding cavity, the electromagnetic coil is used to provide a directional magnetic field when energized and to form two different magnetic poles at the output ends of the two magnetizing heads respectively; the driving mechanism is used to move and rotate the object to be magnetized so as to abut against the output ends of the two magnetizing heads for magnetization.

[0008] Preferably, a connecting portion is provided between the two magnetizing heads of the magnetizing core and the winding cavity, and the two connecting portions form a bending area close to each other.

[0009] Preferably, the cross section of the magnetized core forms an inner cavity approximately in the shape of a "convex" character, the winding cavity is arranged at the tail of the inner cavity, and the magnetizing head is arranged at the head of the inner cavity.

[0010] Preferably, the electromagnetic coil wound in the winding chamber is wound with at least two turns.

[0011] Preferably, the magnetizing head and the surface of the object to be magnetized match each other.

[0012] Preferably, the driving mechanism is any one of a cylinder or a screw transmission mechanism.

[0013] Preferably, the driving mechanism comprises a driving end in contact with the object to be magnetized, and a contact surface of the driving end matches a surface of the object to be magnetized.

[0014] A magnetization method is applied to the above magnetization system, and the method comprises the following steps: S1, placing the object to be magnetized between the driving mechanism and the magnetizing head of the magnetizing core; S2, by controlling the driving mechanism, bringing one side of the object to be magnetized into contact with the magnetizing head, and energizing the electromagnetic coil wound around the magnetizing core to form a directional magnetic field, thereby magnetizing one side of the object to be magnetized; S3, resetting the object to be magnetized by the driving mechanism, and adjusting the object to be magnetized so that the lower side abuts against the magnetizing head again to complete magnetization; S4, looping steps S1 to S3 in sequence until the magnetization of each surface of the object to be magnetized is completed.

[0015] In summary, the beneficial effects of the present invention are: 1. Compared with the traditional enclosed magnetizing device, the present invention is designed with a winding cavity for winding an electromagnetic coil and two magnetizing heads for magnetizing the object to be magnetized. The electromagnetic coil forms a directional magnetic field when energized, and two different magnetic poles are formed on the two magnetizing heads respectively. The driving mechanism presses each surface of the object to be magnetized against the magnetizing head in turn to magnetize each section, effectively avoiding the shape and position tolerance between the magnetizing head and the object to be magnetized, and the size tolerance of the object to be magnetized itself, so that each section of the object to be magnetized has a uniform magnetic flux density.

[0016] 2. Compared with the limited position of the traditional magnetizing device, which can only wind one or two turns of coil on each adjacent magnetizing head, by designing a large-capacity winding cavity in the magnetizing core, it can accommodate the winding of more turns of coil, provide higher magnetizing intensity, and improve magnetizing efficiency.

[0017] The beneficial effects of the remaining additional technical features of the present invention will be described in the specific implementation section of this specification. BRIEF DESCRIPTION OF THE DRAWINGS

[0020] To make the purpose, technical solution and advantages of the present invention clearer, the technical solution of the present invention will be described in detail below. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other implementation methods obtained by ordinary technicians in this field without creative work belong to the scope of protection of the present invention.

[0021] In the description of the present invention, it is necessary to understand that the directions or positional relationships indicated by terms such as “upper”, “lower”, “front”, “back”, “left”, “right”, “inside” and “outside” are based on the directions or positional relationships shown in the accompanying drawings and are only for the convenience of describing the present invention. They do not indicate or imply that the device or element referred to must have a specific direction, be constructed and operated in a specific direction. Therefore, they cannot be understood as limitations on the present invention.

[0022] In the present invention, unless otherwise clearly defined and specified, the terms "installed", "connected", "connected", "fixed" and the like should be understood in a broad sense, for example, they can be fixedly connected, detachably connected, or integrated; they can be mechanically connected, electrically connected, or able to communicate with each other; they can be directly connected, or indirectly connected through an intermediate medium, unless otherwise clearly defined. For those of ordinary skill in the art, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0023] Combination Figure 1 , Figure 2 As shown, the present invention provides a magnetizing system and a magnetizing method thereof, the system comprising a magnetizing core 1, an electromagnetic coil 2 and a driving mechanism 3, the magnetizing core 1 comprising a winding cavity 101 for arranging the electromagnetic coil 2, and two magnetizing heads 102 arranged at intervals for magnetizing an object 4 to be magnetized, the electromagnetic coil 2 is wound on the magnetizing core 1 located in the winding cavity 101, the electromagnetic coil 2 is energized to form a directional magnetic field, and different N-pole and S-pole magnetic poles are formed on the two magnetizing heads 102 respectively.

[0024] The driving mechanism 3 can be any one of a cylinder type or a screw drive type. The driving mechanism 3 is used to reciprocate the object 4 to be magnetized, move the object 4 to be magnetized so that a section of its surface abuts against the magnetizing head 102, and after magnetization is completed in the section, it can be reset and rotated to the next section. The magnetizing head 102 abuts against the surface of the object 4 to be magnetized and is limited at the same time during each magnetization, eliminating the problems of shape and position tolerance and dimensional tolerance, thereby unifying the uniformity of the magnetic flux density of the object 4 to be magnetized.

[0025] Furthermore, a connecting portion 103 is included between the two magnetizing heads 102 of the magnetizing core 1 and the winding cavity 101. The two connecting portions 103 form a bending area 1031 close to each other, shortening the distance between the electromagnetic coil 2 in the winding cavity 101 and the magnetizing head 102, providing a higher magnetic field strength, thereby having a better magnetizing effect and magnetizing efficiency, and shortening the magnetizing time each time.

[0026] Furthermore, the cross-section of the magnetized core 1 forms an inner cavity 104 that is approximately in the shape of a "convex" character, the winding cavity 101 is arranged at the tail of the inner cavity 104, and the magnetizing head 102 is arranged at the head of the inner cavity 104. Compared with the traditional structure in which each magnetizing head 102 can only accommodate one turn of the electromagnetic coil 2, this structure can accommodate more turns of the electromagnetic coil 2, at least two turns or more of the electromagnetic coil 2, thereby providing a stronger and more stable magnetic field strength.

[0027] Furthermore, the magnetizing head 102 matches the surface of the object 4 to be magnetized; the driving mechanism 3 includes a driving end 301 in contact with the object 4 to be magnetized, and the contact surface of the driving end 301 matches the surface of the object 4 to be magnetized, so as to make the abutment between the object 4 to be magnetized and the magnetizing head 102 tighter, further eliminate tolerance, and have a more uniform magnetization effect.

[0028] Combination Figure 3As shown, specifically, the magnetization method of the magnetization system applied to the above-mentioned magnetization system includes the following steps: placing an object 4 to be magnetized between a driving mechanism 3 and a magnetization head 102 of a magnetization core 1; by controlling the driving mechanism 3, one side of the object 4 to be magnetized is brought into contact with the magnetization head 102, and then the electromagnetic coil 2 wound on the magnetization core 1 is energized to form a directional magnetic field, and an N pole and an S pole are formed on the two magnetization heads 102 respectively, when the object 4 to be magnetized is in close contact with the N-pole magnetization head 102, the close contact area forms an S-pole magnetic pole; when the object 4 to be magnetized is in close contact with the S-pole magnetization head 102, the close contact area forms an N-pole magnetic pole, thereby realizing magnetization of a section of one side of the object 4 to be magnetized, so that The object 4 to be magnetized is reset by the driving mechanism 3, and the object 4 to be magnetized is adjusted to the next area where the object 4 needs to be charged, and the magnetization head 102 is abutted again to complete the magnetization. The above steps are repeated in sequence as needed to complete the magnetization of each surface of the object 4 to be magnetized. This method avoids the magnetization gap between the object 4 to be magnetized and the magnetization head 102 by abutting the object 4 to be magnetized and the shape and position tolerance between the magnetization head 102 and the object 4 to be magnetized, as well as the dimensional tolerance of the object 4 to be magnetized in the process itself, so that the object 4 to be magnetized and the magnetization head 102 are fixed each time during magnetization, and has the characteristic of uniform magnetization effect.

[0029] The above is only a specific embodiment of the present invention, but the protection scope of the present invention is not limited thereto. Any person skilled in the art can easily think of changes or substitutions within the technical scope disclosed by the present invention, which should be included in the protection scope of the present invention. Therefore, the protection scope of the present invention should be based on the protection scope of the claims.
