Technical Field
[0001] This utility model relates to the field of magnetic steel detection technology, and in particular to a detection and arrangement device for irregularly shaped magnetic steel arc surfaces. Background Technology
[0002] Neodymium iron boron magnets are tetragonal crystals formed from neodymium, iron, and boron. They are an important permanent magnet material with excellent properties such as high energy product, high coercivity, and high remanence, and are widely used in fields such as electronic medical devices and aerospace.
[0003] With the continuous advancement of technology, the application requirements for neodymium iron boron (NdFeB) magnets are becoming increasingly stringent. The shapes of NdFeB magnets are now designed in a variety of forms, including squares, fan shapes, circles, tile shapes, and irregular shapes. To meet the high-quality requirements of customers, the surface appearance of these NdFeB magnets must pass a full inspection by inspectors before shipment. A qualified appearance must be free of defects such as chipped edges, cracks, and missing corners. For certain complex-shaped magnets, the full inspection involves inspectors visually identifying the irregular outline and then using hand tools to rearrange the irregularly arranged magnets on a flat surface, ensuring that the curved surfaces of the magnets are all facing upwards. However, visual identification by inspectors is inefficient, difficult, and cannot guarantee completely correct arrangement, posing a risk of missed inspections. Repeated inspections are necessary, making the arrangement and inspection process time-consuming and labor-intensive, which does not meet daily inspection needs.
[0004] Therefore, it is necessary to develop a detection and arrangement device for irregularly shaped magnetic steel arc surfaces to solve the above problems. Utility Model Content

[0016] The present invention achieves the following technical advantages over the prior art: This utility model discloses an irregularly shaped magnet arc surface inspection and arrangement device. Through the contoured slots arranged on a fixture plate, the arc surface of the irregularly shaped magnet to be inspected is inserted downwards into the contoured slots. Then, after being flipped by a baffle on the fixture plate, with the fixture plate on top and the baffle on the bottom, the fixture plate is vertically removed.

Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0022] To make the above-mentioned objectives, features and advantages of this utility model more apparent and understandable, the utility model will be further described in detail below with reference to the accompanying drawings and specific embodiments.
[0023] This utility model provides a detection and arrangement device for irregularly shaped magnetic steel arc surfaces, such as... Figures 1 to 7 As shown, the fixture includes a jig plate 1 and a baffle plate 2. The jig plate 1 has multiple contoured slots 11 for embedding irregularly shaped magnets 3, each slot 11 being formed by an inward indentation of the surface of the jig plate 1. The irregularly shaped magnet 3 includes two or more arc-shaped surfaces 31 to be inspected, wherein one end of two arc-shaped surfaces 31 is connected to form an embedding end 33, and the other end of the two arc-shaped surfaces 31 extends away from the embedding end 33 with a gradually increasing distance between them. The contoured slot 11 has two arc-shaped inner sidewalls 111 extending along its length. Furthermore, the two arc-shaped inner sidewalls 111 are adapted to or conformally set to the two arc-shaped surfaces 31 to be inspected; in the first state, the two arc-shaped surfaces 31 to be inspected of the irregular magnet 3 can be adapted to fit and fit with the arc-shaped inner sidewalls 111 of the conformal groove 11 and the embedded end 33 is located in the conformal groove 11; in the second state, the baffle 2 can be engaged with the side of the fixture plate 1 where the conformal groove 11 is arranged to support the inverted irregular magnet 3. Under the support of the baffle 2, all irregular magnets 3 can be dislodged from the conformal groove 11 on the fixture plate 1.
[0024] In some embodiments, such as Figure 6 and Figure 7 As shown, the irregularly shaped magnet 3 also includes a support plane 32, and the other ends of the two arc-shaped surfaces 31 to be inspected are respectively connected to the two ends of the support plane 32; in the first state, the support plane 32 is arranged parallel to the surface of the fixture plate 1; in the second state, the surface of the baffle 2 abuts against the support plane 32 to support the irregularly shaped magnet 3.
[0025] In some embodiments, such as Figure 2 As shown, the arc-shaped surface 31 to be inspected is a concave surface, and the arc-shaped inner sidewall 111 of the contoured groove 11 is a convex surface, and the convex surface can fit and conform to the concave surface.
[0026] In some embodiments, such as Figure 2 As shown, the cross-sectional shape of the contoured slot 11 is the same as that of the irregularly shaped magnet 3, and the contoured slot 11 is configured to allow the irregularly shaped magnet 3 to freely embed into or freely dislodge from the contoured slot 11. Here, the cross-section of the contoured slot 11 and the cross-section of the irregularly shaped magnet 3 both refer to the cross-section along the vertical direction.
[0027] In some embodiments, such as Figure 2 As shown, a connecting part 13 is provided between two adjacent contoured slots 11. The top of the connecting part 13 is higher than the contoured slot 11 and the top of the connecting part 13 has an arc-shaped structure.
[0028] In some embodiments, such as Figure 1 As shown, multiple contoured slots 11 are arranged at equal intervals on the fixture plate 1.
[0029] In some embodiments, both the fixture plate 1 and the baffle 2 are 3D printed using photosensitive resin.
[0030] In some embodiments, such as Figure 7 As shown, the depth dimension of the contoured groove 11 is equal to the height dimension of the support plane 32 of the irregular magnet 3 from the embedded end 33, so that the irregular magnet 3 can move freely without hindrance during the arrangement process.
[0031] In some embodiments, such as Figure 1 and Figure 5 As shown, the fixture plate 1 is provided with a recess 12, and the baffle 2 is provided with a protrusion 21, which can be adapted to be inserted into the recess 12; or the fixture plate 1 is provided with a protrusion 21, and the baffle 2 is provided with a recess 12, which can be adapted to be inserted into the recess 12.
[0032] In some embodiments, such as Figure 1 and Figure 5 As shown, recessed handholds 4 are provided at both ends of the fixture plate 1 and the baffle 2.
[0033] In use, the inspector first places irregularly shaped magnets 3 on the upper part of the jig plate 1 with the contoured groove 11. By tilting the jig plate 1, the irregularly shaped magnets 3 move repeatedly on the surface of the jig plate 1. Most of the irregularly shaped magnets 3 freely enter the groove. After entering, the irregularly shaped magnets 3 are in a state where both arc surfaces face down. When the coverage rate is about 80%, the inspector removes the irregularly shaped magnets 3 that have not entered the surface. Then, the flipping operation is performed with the jig plate 1 at the bottom and the baffle 2 at the top. The baffle 2 is combined with the jig plate 1. During positioning, the concave part 12 of the jig plate 1 and the convex part 21 of the baffle 2 cooperate. After combination, the outer contours of the baffle 2 and the jig plate 1 are aligned. Observing that there is no obvious gap between the two plates indicates that there are no impurities or residual magnets. Otherwise, it will affect the flipping operation. The inspectors flip the two assembled plates 180 degrees simultaneously, with fixture plate 1 on top and baffle plate 2 on the bottom. Then, fixture plate 1 is removed vertically, and the irregularly shaped magnets 3 will fall neatly into the inspection area of baffle plate 2. At this time, all the double arc surfaces of the irregularly shaped magnets 3 are placed facing upwards, which makes it convenient for inspectors to perform a full inspection of the arc surface appearance and screen out unqualified products with chipped edges, cracks, missing corners, etc.
[0034] Inspectors use fixture plate 1 to neatly arrange irregularly shaped magnets 3. The operation is simple, and after arrangement, the irregularly shaped magnets 3 have a consistent posture. Inspection is then carried out using baffle 2, which covers the inspection area filled with neatly arranged magnets, allowing for full inspection of the curved surfaces of the magnets and significantly improving the efficiency of the arrangement and inspection of irregularly shaped magnets 3. This method of arrangement and inspection is simple, effective, and low-cost, making it easy to implement and suitable for batch use of irregularly shaped magnets 3.
[0035] This utility model uses specific examples to illustrate its principles and implementation methods. The above description of the embodiments is only for the purpose of helping to understand the method and core idea of this utility model. At the same time, for those skilled in the art, there will be changes in the specific implementation methods and application scope based on the idea of this utility model. In summary, the content of this specification should not be construed as a limitation of this utility model.
