[0002] Magnet tiles are typically made of magnetic materials such as ferrite and neodymium iron boron, and are key components in permanent magnet motors that generate magnetic fields.

[0003] Defects are inevitable during the production of magnetic tiles. Compared to qualified magnetic tiles, defective tiles significantly reduce their magnetic and mechanical properties, thus greatly affecting the lifespan and operating efficiency of permanent magnet motors. Therefore, detecting and eliminating defective magnetic tiles is the primary task in ensuring the quality of magnetic tile products during production.

[0004] In existing technologies, the detection method for defects in magnetic tiles typically involves manually striking the tile with a metal block to generate sound, and then using human auditory experience to determine the presence of internal defects by judging the crispness or dullness of the sound. However, manual inspection is not only inefficient, but also prone to misjudgment, thus affecting product quality. Utility Model Content

[0033] To enable those skilled in the art to better understand the present invention, the technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of the present invention, and not all of them. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without creative effort are within the scope of protection of the present invention.

[0034] In this document, the term "embodiment" means that a particular feature, structure, or characteristic described in connection with an embodiment may be included in at least one embodiment of the present invention. The appearance of this phrase in various places throughout the specification does not necessarily refer to the same embodiment, nor is it a separate or alternative embodiment mutually exclusive with other embodiments. It will be explicitly and implicitly understood by those skilled in the art that the embodiments described herein can be combined with other embodiments.

[0035] Please see Figures 1-4 The present invention provides a first aspect of a magnetic tile heating device, comprising: a power mechanism 1, an oscillation mechanism 2 connected to the power mechanism 1, an arrangement mechanism 3 connected to the oscillation mechanism 2, a heating mechanism 4 disposed on the arrangement mechanism 3, and a feeding mechanism 5 connected to the arrangement mechanism 3.

[0036] In some embodiments, the power mechanism 1 is a part for generating power and transmitting it to subsequent components or actuators. An exemplary first power mechanism 1 may include a motor 11, which may convert electrical energy into mechanical energy based on the principle of electromagnetic induction.

[0037] In some embodiments, the oscillation mechanism 2 is a part used to oscillate the magnetic tiles, so that the magnetic tiles can enter the arrangement mechanism 3 in a certain state. The specific oscillation process will be further described below.

[0038] Furthermore, the oscillation mechanism 2 includes a driving wheel 21, a driven wheel 22 driven by the driving wheel 21, a rotating shaft 23 connected to the driven wheel 22, a cam 24 connected to the rotating shaft 23, and an oscillating hopper 25 adapted to the cam 24. In some embodiments, the driving wheel 21 is a wheel that actively provides power in the mechanical transmission system. It can be connected to the output shaft of the motor 11, and then the power is transmitted to the driven wheel 22 via a belt through the drive motor 11. The driven wheel 22 is a wheel that passively receives power in the mechanical transmission system. It is driven to rotate by the friction of the belt.

[0039] In some embodiments, one end of the rotating shaft 23 is connected to the driven wheel 22, and the other end is connected to the cam 24. When the driven wheel 22 is driven to rotate, it will drive the rotating shaft 23 and the cam 24 to rotate synchronously. In some embodiments, the cam 24 is a disc-shaped component that rotates around a fixed axis and has a variable diameter. The cam 24 is adapted to the vibrating hopper 25 for vibrating the magnetic tiles in the vibrating hopper 25.

[0040] In some embodiments, the vibrating hopper 25 is used to vibrate the magnetic tiles to adjust their state. Further, the vibrating hopper 25 includes a storage bin 251, a sliding plate 252 disposed on the storage bin 251, a sliding seat 253 slidably connected to the sliding plate 252, and a vibrating plate 254 connected to the sliding plate 252. The storage bin 251 is a funnel-shaped structure that is narrow at the top and wide at the bottom, used to accommodate the magnetic tiles. The sliding plate 252 is disposed at the bottom of the storage bin 251. In some embodiments, the magnetic tiles in the storage bin 251 can be vibrated by raising and lowering the sliding plate 252 to adjust the shape of the magnetic tiles, for example, so that the magnetic tiles enter the arranging mechanism 3 in a vertical state.

[0041] Furthermore, the sliding plate 252 is provided with a through hole, and the sliding seat 253 has a structure with a columnar connector. The columnar connector on the sliding seat 253 can be slidably connected to the through hole of the sliding plate 252, so that the sliding plate 252 can only move up and down in the direction set by the columnar connector of the sliding seat 253. In some embodiments, the vibrating plate 254 has a beveled structure. The vibrating plate 254 is adapted to the cam 24 for raising and lowering the storage bin 251 to vibrate the magnetic tiles in the storage bin 251. Specifically, after the beveled structure of the vibrating plate 254 abuts against the cam 24… First, the higher end of the inclined side of the vibrating plate 254 abuts against the cam 24. Then, as the cam 24 rotates, it abuts against the higher end to the lower end of the inclined side of the vibrating plate 254 in sequence. During the abutment process, the vibrating plate 254 will continue to rise under the action of the cam 24. After the cam 24 separates from the vibrating plate 254, the sliding plate 252 will slide down along the columnar connector of the sliding seat 253 to the initial position until it abuts against the cam 24 again and then rises again. Thus, the cam 24 rotates to make the sliding plate 252 rise and fall, thereby vibrating the magnetic tiles in the storage bin 251 to adjust the shape of the magnetic tiles.

[0042] In some embodiments, the arrangement mechanism 3 is a part used to arrange the magnetic tiles so that the magnetic tiles can be heated uniformly in a vertical shape. Those skilled in the art will understand that in this embodiment, the magnetic tiles are tile-shaped arc structures.

[0043] Furthermore, the arrangement mechanism 3 includes: an arrangement cylinder 31, a material distribution head 32 disposed in the arrangement cylinder 31, a material distribution column 33 connected to the material distribution head 32, and a quartz sleeve 34 sleeved on the outer periphery of the arrangement cylinder 31. In some embodiments, the arrangement cylinder 31 is a hollow structure, and one end of the material distribution head 32 is conical. The arrangement cylinder 31 and the material distribution head 32 cooperate to arrange the magnetic tiles. The specific arrangement process will be further described below.

[0044] In some embodiments, the distributing head 32 is disposed within the hollow structure of the arranging cylinder 31. The gap between the distributing head 32 and the arranging cylinder 31 is annular, and this gap is adapted to the structure of the magnetic tile. This allows the magnetic tile to enter the gap between the distributing head 32 and the arranging cylinder 31 only when it is in a vertical position, through the adaptation of the arc-shaped tile to the annular gap, thereby vertically arranging the magnetic tile in the gap between the distributing head 32 and the arranging cylinder 31. On the other hand, the conical design of the distributing head 32 allows the magnetic tile to continuously change direction during oscillation until it enters the gap between the distributing head 32 and the arranging cylinder 31 in a vertical position.

[0045] In some embodiments, the material distribution column 33 is connected to the material distribution head 32 and is used to receive the magnetic tiles after the material distribution head 32 and the arranging cylinder 31 are arranged and to perform secondary arrangement. Further, the material distribution column 33 is columnar and has an arc-shaped tile-shaped groove on its outer periphery. The arc-shaped tile-shaped groove on the material distribution column 33 is adapted to the magnetic tiles so that the magnetic tiles after the material distribution head 32 and the arranging cylinder 31 are arranged can only pass through the arc-shaped tile-shaped groove on the material distribution column 33.

[0046] Furthermore, the material distribution column 33 is also connected to the power mechanism 1, so that the motor 11 drives the material distribution column 33 and the material distribution head 32 to rotate. Thus, the rotation of the material distribution column 33 allows the magnetic tiles in the gap between the material distribution head 32 and the arrangement cylinder 31 to enter the arc-shaped tile-shaped groove on the material distribution column 33 for secondary arrangement. Also, the rotation of the material distribution head 32 causes the magnetic tiles to continuously change direction during the oscillation process.

[0047] In some embodiments, the heating mechanism 4 is a part used to heat the magnetic tiles. Further, the heating mechanism 4 includes a heating wire 41 wound around the outer periphery of the arrangement cylinder 31. The heating wire 41 is wound around a quartz sleeve 34, and the position of the quartz sleeve 34 is adapted to the position of the material distribution column 33. Thus, the heating wire 41 uses the thermal effect of electric current to convert electrical energy into heat energy to heat the magnetic tiles arranged in the arrangement mechanism 3. On the other hand, the quartz sleeve 34 conducts heat evenly, making the magnetic tiles more evenly heated and improving the heating effect, so as to facilitate subsequent internal defect detection.

[0048] In some embodiments, the feeding mechanism 5 is a part for conveying magnetic tiles. In some embodiments, the feeding mechanism 5 includes: a feeding electromagnet 51 and a conductive slip ring 52 connected to the feeding electromagnet 51. In some embodiments, the feeding electromagnet 51 is disposed in the distributing column 33. The feeding electromagnet 51 is used to control the feeding speed of the magnetic tiles in the arc-shaped groove of the distributing column 33. For example, the feeding can be stopped by the feeding electromagnet 51 adsorbing the magnetic tiles in the arc-shaped groove of the distributing column 33, and the feeding speed of the magnetic tiles can be adjusted by stopping the adsorption of the magnetic tiles in the arc-shaped groove of the distributing column 33 by the feeding electromagnet 51.

[0049] In some embodiments, the conductive slip ring 52 is a precision electromechanical component capable of transmitting power, electrical signals, and data signals between rotating and stationary components, thereby supplying power to the feeding electromagnet 51 located in the feeding column 33 through the conductive slip ring 52.

[0050] The second aspect of this utility model provides a magnetic tile defect detection line, including the magnetic tile heating device described in Embodiment 1.

[0051] In some embodiments, after the magnetic tile is heated by the magnetic tile heating device, the temperature distribution characteristics of the magnetic tile can be obtained by an infrared thermal imager. When an uneven temperature distribution of the magnetic tile is detected, it can be determined that the magnetic tile has a defect. For example, if the temperature of a certain part of the magnetic tile is significantly higher than that of other parts, it can be determined that there is a defect there.

[0052] Finally, it should be noted that the embodiments disclosed in this utility model are merely preferred embodiments of this utility model and are only used to illustrate the technical solutions of this utility model, not to limit it. Although this utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the spirit and scope of the technical solutions of the various embodiments of this utility model.
