Description

Technical Field

[0001] The utility model relates to the technical field of NdFeB processing, in particular to an inclined separation device for magnetic steel. Background Art

[0002] Neodymium iron boron magnets are currently the most powerful permanent magnets with hard and brittle properties. After magnetization, magnets are widely used in many industries, such as industrial and household appliances such as generators, digital cameras, mobile phones, magnetic equipment, and other scenarios. Among them, for special-shaped magnets, the shapes need to be arranged neatly according to the polar design before magnetization to ensure polar consistency, and then magnetized in batches. Currently, manual tweezers are mostly used to identify special-shaped features and arrange them.

DETAILED DESCRIPTION

[0024] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0025] The purpose of the utility model is to provide an inclined sorting device for magnetic steel to solve the problems existing in the prior art, make the sorting simple and effective, reduce the cost, and meet the needs of mass production of magnetic steel.

[0026] In order to make the above-mentioned objects, features and advantages of the present invention more obvious and easy to understand, the present invention is further described in detail below with reference to the accompanying drawings and specific implementation methods.

[0027] like Figure 1-Figure 5 As shown, this embodiment provides an inclined sorting device for magnetic steel, including an operating table 1, an inclined jig 2, a sorting jig 3 and a storage box 5. The operating table 1 includes a first platform 11 and a second platform 12. The storage box 5 is placed on the first platform 11. The storage box 5 is used to hold the magnetic steel 4 sorted by the sorting jig 3. The second platform 12 is located above the first platform 11. The inclined jig 2 is installed on the upper end of the second platform 12, and the sorting jig 3 is installed on the upper end of the inclined jig 2, so that the sorting jig 3 is also tilted to ensure that the magnetic steel 4 can slide down. The lower end surface of the sorting jig 3 is aligned with the upper end of the inclined jig 2. A sliding gap is formed between the surfaces, and the storage box 5 is located below the end of the sliding gap, so that the screened magnetic steel 4 falls into the storage box 5 through the sliding gap. A plurality of sorting holes are provided on the sorting jig 3, so that multiple magnetic steels 4 can be sorted at the same time, so that the magnetic steel 4 with the C angle on top (i.e., the first magnetic steel 41) can be confined in the sorting hole, and the magnetic steel 4 with the C angle on the bottom (i.e., the second magnetic steel 42) can fall into the sliding gap through the sorting hole and slide into the storage box 5 through the sliding gap, so as to facilitate cyclic sorting, improve collection efficiency and collection accuracy, and the overall structure is simple and the cost is low.

[0028] Specifically, a plurality of columns are installed on the upper end surface of the first platform 11, and the corners of the lower end surface of the second platform 12 are respectively connected to the upper ends of the columns, so that there is a distance between the first platform 11 and the second platform 12, and the distance between the first platform 11 and the second platform 12 is greater than the height of the storage box 5, thereby allowing the storage box 5 to move smoothly.

[0029] The first end of the first platform 11 extends out of the second platform 12 , and the storage box 5 is placed close to the first end of the first platform 11 , so that the storage box 5 can smoothly receive the magnet 4 that falls through the sliding gap.

[0030] The tilting jig 2 includes an inclined plate 21 and a support portion 22. The lower end of the support portion 22 is mounted on the upper end surface of the second platform 12. The upper end of the support portion 22 is fixed to one end of the lower end surface of the inclined plate 21. The other end of the inclined plate 21 is mounted on the second platform 12. Then, one end of the inclined plate 21 is raised by the support portion 22 so that the inclined plate 21 can be tilted. The angle between the inclined plate 21 and the second platform 12 is an acute angle, preferably 15°-25°, which facilitates the magnetic steel 4 to slide down due to gravity and ensures the normal progress of the screening process.

[0031] A first baffle 25 is installed on each side of the upper end surface of the inclined plate 21. The two first baffles 25 can be detachably connected to the two sides of the lower end surface of the sorting jig 3, thereby realizing the connection between the inclined plate 21 and the sorting jig 3. A first groove 23 is formed between the two first baffles 25 and the upper surface of the inclined plate 21, and a sliding gap is formed between the first groove 23 and the lower end surface of the sorting jig 3; each first baffle 25 is provided with a second baffle 26 at the position corresponding to the lowest end of the inclined plate 21, and one side of each second baffle 26 abuts against the lowest end of the sorting jig 3, and then the sorting jig 3 is limited by the second baffle 26 to prevent the sorting jig 3 from shaking back and forth when the magnetic steel 4 is manually moved, thereby reducing the sorting efficiency.

[0032] The upper surface of the sorting fixture 3 is also provided with an installation mark 34 to remind the inspector of the installation direction during installation.

[0033] A second groove 33 is provided on each side of the lower end surface of the sorting jig 3 , and the two first baffles 25 are respectively embedded in the two second grooves 33 to achieve a detachable connection between the sorting jig 3 and the inclined plate 21 .

[0034] The support portion 22 is provided with a third groove 24 , and a bolt passes through the third groove 24 to achieve connection between the support portion 22 and the second platform 12 .

[0035] Each sorting hole includes a first hole 31 and a second hole 32 that are connected internally, and the first hole 31 is located at the upper end of the second hole 32. The shape of the first hole 31 is consistent with the shape of the magnetic steel 4 with the C angle at the bottom, so that the magnetic steel 4 can more conveniently enter the first hole 31 when moving above the sorting fixture 3. The second hole 32 is a rectangular hole, and the rectangular hole can allow the magnetic steel 4 with the C angle at the bottom to pass through, and then when the magnetic steel 4 with the C angle at the bottom reaches the position of the first hole 31, it can fall through the first hole 31 to the second hole 31. The magnets 4 are then collected in the second cavity 32 through the sliding gap and finally collected in the storage box 5 for cyclic sorting. A third baffle 311 is provided at the transition between the first cavity 31 and the second cavity 32. This baffle 311 blocks the magnets 4 with the C-angle facing upward. When the magnets 4 with the C-angle facing upward reach the first cavity 31, the third baffle 311 blocks them, preventing them from entering the second cavity 32, thereby completing the screening of the two orientations of the magnets 4. During the screening process, the magnets 4 entering the first cavity 31 have a height difference due to their different orientations, such as with the C-angle facing upward or downward, which facilitates sorting by the third baffle 311. The magnets 4 with the C-angle facing downward are lower than the third baffle 311, allowing them to enter the second cavity 32 smoothly under the action of gravity. However, the magnets 4 with the C-angle facing upward are confined within the first cavity 31 by the third baffle 311 and cannot enter the second cavity 32.

[0036] The second hole 32 is provided so that the second magnet 42 (i.e., the magnet 4 with the C angle at the bottom) entering the second hole 32 can continue to slide freely into the sliding gap under the action of gravity. The length and width dimensions of the second hole 32 are designed to be larger than the diagonal dimensions of the corresponding magnet 4 to prevent the magnet 4 from flipping over in the second hole 32 and causing jamming.

[0037] The sorting holes on the sorting fixture 3 are arranged in an array.

[0038] The sorting jig 3 is made of photosensitive resin material through 3D printing, with high precision and fine surface, and will not damage or scratch the surface coating of the magnetic steel 4 when it contacts the magnetic steel 4.

[0039] The method of using this embodiment is:

[0040] The inspector first places the magnets 4 on the top of the sorting jig 3. By repeatedly moving the magnets 4, the sorting jig 3 restricts the magnets 4 with the C angle at the top (i.e., the first magnet 41) to remain in the first hole 31, and the magnets 4 with the C angle at the bottom (i.e., the second magnet 42) are sorted out and enter the second hole 32. Due to the tilt of the tilting jig 2, the sorting jig 3 is also in an angled state. At this time, the magnets 4 that slide out of the second hole 32 slide back into the recovery box 5 through the sliding gap under the action of gravity. The above sorting operation can be repeated to complete the tilted sorting operation of the magnets 4. The inspector repeatedly moves the magnets 4 to fill the first hole 31 of the sorting jig 3 with the magnets 4 with the C angle at the top. The magnets 4 are neatly arranged and have a consistent posture, which ensures the correctness of the sorting. Then, the multiple sorting jigs 3 filled with magnets 4 are magnetized as a whole to meet the batch magnetization operation of the magnets 4.

[0041] The present invention uses specific examples to illustrate the principles and implementation methods of the present invention. The above examples are only intended to help understand the method and core concept of the present invention. At the same time, those skilled in the art will find that the specific implementation methods and application scopes may vary based on the concept of the present invention. In summary, the contents of this specification should not be construed as limiting the present invention.
