Description

Technical Field

[0001] This utility model relates to the field of neodymium iron boron strong magnet production technology, specifically a storage device for neodymium iron boron strong magnet production. Background Technology

[0002] Neodymium magnets, also known as neodymium iron boron magnets, are tetragonal crystals formed from neodymium, iron, and boron. These magnets are the second strongest permanent magnets in terms of magnetic properties after holmium magnets at absolute zero, and are also the most commonly used rare-earth magnets. Neodymium iron boron magnets are widely used in electronic products such as hard drives, mobile phones, headphones, and battery-powered tools. Neodymium iron boron permanent magnets need to be stored for a period of time during processing, during which time they are prone to oxidation. Therefore, storage devices are required to store neodymium iron boron magnets.

[0003] Patent document CN217599206U discloses a storage device for the production of neodymium iron boron (NdFeB) strong magnets, including a box. A base is fixedly installed at the bottom of the inner cavity of the box. A movable groove is formed inside the base, and a movable block is slidably connected inside the movable groove. An adjusting plate is fixedly installed on the top of the movable block. The adjusting plate is connected to the base via a rod. A vertical plate is fixedly installed at the inner end of the adjusting plate, and the two vertical plates are symmetrically arranged and used in conjunction. A bottom plate is placed between the two vertical plates. This invention, by assembling the two vertical plates, allows adjustment according to the size of the NdFeB strong magnets placed inside. Furthermore, the addition of a limiting post in the middle allows for selective installation to store and fix annular NdFeB strong magnets, preventing them from collapsing and causing damage after being placed inside the box. This device can neatly place NdFeB strong magnets of different shapes, thereby effectively improving storage efficiency. However, the existing technology still has shortcomings:

[0004] In existing technologies, when there are a large number of NdFeB magnets, they need to be stacked. However, when stacked, it is not convenient to limit and fix the top. At the same time, stacking multiple NdFeB permanent magnets together can easily crush them. Furthermore, it is inconvenient to remove NdFeB magnets from the box, as the ones that were first placed at the bottom are prone to falling off when being removed. This makes the device inconvenient to use and reduces its practicality.

[0005] The information disclosed in this background section is intended only to enhance the understanding of the overall background of this utility model and should not be construed as an admission or in any way implying that the information constitutes prior art known to those skilled in the art.

[0006] The technical problem to be solved by this utility model is to overcome the above-mentioned defects and provide a storage device for the production of neodymium iron boron strong magnets.

[0007] To solve the above-mentioned technical problems, the technical solution provided by this utility model is: a storage device for the production of neodymium iron boron strong magnets, comprising:

[0008] The housing has an electromagnet installed at the rear end of its inner wall;

[0009] A partition structure is provided inside the box body. The partition structure includes multiple vertical plates arranged at equal intervals.

[0011] The pressure structure is located on the upper part of the box body. The pressure structure includes a rectangular groove formed at the upper part of both ends of the inner wall of the box body. A screw is rotatably inserted into both ends of the inner wall of the rectangular groove at one end. The top end of the screw extends to the top of the box body and is fixedly connected to a turntable at the end. A limit block is slidably connected in the rectangular groove. One end of the limit block is threadedly connected to the screw. A pressure plate is fixedly connected between the two limit blocks. A second guide rod is fixedly connected to the top of the inner wall of the pressure plate. There are multiple second guide rods, which are equally spaced. A third spring is sleeved on the outside of the second guide rod. A pressure rod is slidably connected to the second guide rod and passes through the bottom of the pressure plate.

[0012] Furthermore, the bottom two ends of the inner wall of the box are provided with sliding grooves, and the bottom two ends of the vertical plate are fixedly connected with sliders, which are slidably connected in the sliding grooves.

[0013] Furthermore, the positioning structure includes:

[0014] A cavity is formed inside the slider and located at the front end of the box body. A movable plate is slidably connected to the inner wall of the cavity.

[0015] The pressing sleeve rod is inserted into the upper front end of the inner wall of the cavity, and the pressing sleeve rod is fixedly connected to one end of the movable plate;

[0020] Furthermore, ventilation frames are installed at both ends of the housing, and filters are installed inside the ventilation frames.

[0021] Furthermore, a sealed door is provided on the front side of the enclosure.

[0022] The advantages of this invention compared to existing technologies are as follows: The partition structure divides the housing into multiple storage areas, allowing for the vertical storage of neodymium iron boron (NdFeB) magnets.

Detailed Implementation

[0030] Exemplary embodiments will now be described in detail, examples of which are illustrated in the accompanying drawings. When the following description relates to the drawings, unless otherwise indicated, the same numerals in different drawings denote the same or similar elements. The embodiments described in the following exemplary embodiments do not represent all embodiments consistent with this disclosure. Rather, they are merely examples of apparatuses consistent with some aspects of this disclosure as detailed in the appended claims.

[0031] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the scope of protection of the present utility model.

[0032] like Figures 1 to 6 As shown, this embodiment proposes a storage device for the production of neodymium iron boron strong magnets, including a box 1. An electromagnet 2 is installed on the rear end of the inner wall of the box 1. The surface of the electromagnet 2 is provided with soft rubber for cushioning to prevent the neodymium iron boron strong magnet from breaking due to collision. When the electromagnet 2 is energized, it generates magnetism. Due to the principle of like poles repulsion, the neodymium iron boron strong magnet is pushed out, which makes it easy to take out the stored neodymium iron boron strong magnet.

[0033] The box 1 has a partition structure 3 inside, which includes multiple vertical plates 33 arranged at equal intervals. The bottom ends of the inner wall of the box 1 are provided with sliding grooves 31. The bottom ends of the vertical plates 33 are fixedly connected with sliders 32, which are slidably connected in the sliding grooves 31. The top of the vertical plates 33 is provided with multiple limiting grooves 34. The bottom of the inner wall of the limiting grooves 34 is fixedly connected with springs 35, and the top of the limiting grooves 34 is slidably connected with limiting rods 36. The limiting rods 36 are located above the springs 35, and the top of the limiting rods 36 is fixedly connected with a partition sleeve 37, which is slidably connected to the top of the outer side of the vertical plates 33. The setting of the limiting grooves 34 and the limiting rods 36 facilitates the limiting and guiding of the movement of the partition sleeves 37. The vertical plates 33 clamp and limit the two sides of the vertically placed neodymium iron boron strong magnet.

[0034] The front end of the partition structure 3 is provided with a positioning structure 4. The positioning structure 4 includes a cavity 41 opened inside the slider 32. The cavity 41 is located at the front end of the box body 1. A movable plate is slidably connected to the inner wall of the cavity 41. A slide rod is fixedly connected to the middle of the inner wall of the cavity 41, and the movable plate is slidably connected to the slide rod. A pressing sleeve 42 is inserted through the upper part of the front end of the inner wall of the cavity 41 and is fixedly connected to one end of the movable plate. A snap-fit ​​sleeve 43 is inserted through the lower part of the front end of the inner wall of the cavity 41 and is fixedly connected to the other end of the movable plate. Guide inner rods 44 are fixedly connected to both ends of the inner wall of the cavity 41. The pressing sleeve 42 is slidably connected to the guide inner rod 44, and the snap-fit ​​sleeve 43 is slidably connected to the guide inner rod 44. The sliding rod and the guide inner rod are connected to each other. The design of guide rod 44 facilitates the limiting and guiding of the movement of the movable plate, pressing sleeve rod 42, and locking sleeve rod 43. A spring 45 is sleeved on the outside of guide rod 44. A positioning groove 46 is opened at the front end of the inner wall of the sliding groove 31. There are multiple positioning grooves 46, which are equally spaced. By pressing the pressing sleeve rod 42, the movable plate slides on the guide rod 44 and squeezes the spring 45. At this time, the locking sleeve rod 43 disengages from the positioning groove 46. Then, the vertical plate 33 is moved left and right in the sliding groove 31 to a suitable position. After releasing the pressing sleeve rod 42, the locking sleeve rod 43 is driven to lock into the positioning groove 46 at the corresponding position under the elastic action of the spring 45. This makes the box 1 divided into multiple storage areas for the separate vertical storage of neodymium iron boron strong magnets.

[0035] The upper part of the housing 1 is provided with a pressing structure 5. The pressing structure 5 includes rectangular grooves 51 opened at both ends of the inner wall of the housing 1. Screws 52 are rotatably inserted into both ends of the inner wall of one end of the rectangular groove 51. The top of the screws 52 extends to the top of the housing 1 and is fixedly connected to a turntable 53 at the end. The turntable 53 is provided with a locking pin structure. Specifically, a locking screw is threaded onto the turntable 53. Several locking grooves are opened on the side of the housing 1 near the turntable 53 to cooperate with the locking screw. The locking grooves are circumferentially distributed. After adjustment, the locking screw is screwed into the locking groove to prevent the turntable 53 from rotating accidentally, thus improving the stability of use. Limit blocks are slidably connected in the rectangular grooves 51. One end of the limit block is threaded onto the screw 52. A pressure plate 54 is fixedly connected between the two end limit blocks. A guide inner rod 55 is fixedly connected to the top. There are multiple guide inner rods 55, which are equally spaced. A spring 56 is sleeved on the outside of the guide inner rod 55. A pressing rod 57 is slidably connected to the guide inner rod 55. The pressing rod 57 is inserted into the bottom of the pressure plate 54. The top of the pressing rod 57 is provided with a limiting ring, which is fixedly connected to the bottom of the spring 56. The rotating turntable 53 drives the screw 52 to rotate. The screw 52 drives the limiting block to slide up and down in the rectangular groove 51, thereby driving the pressure plate 54 to move downward. At this time, the pressing rod 57 that comes into contact with the placed neodymium iron boron strong magnet slides upward on the guide inner rod 55 and squeezes the spring 56. The pressing rods 57 that do not come into contact with the neodymium iron boron strong magnet limit its surroundings. This allows for the vertical placement and storage of neodymium iron boron strong magnets of different shapes and sizes, which is convenient for placement.

[0036] Ventilation frames 6 are installed at both ends of the housing 1. Filter screens 61 are installed inside the ventilation frames 6. The ventilation frames 6 can enhance the ventilation effect inside the housing 1, and the filter screens 61 can block dust and impurities in the air.

[0037] The front of the enclosure 1 is equipped with a sealing door 7, which can seal the inside of the enclosure 1 after a neodymium iron boron strong magnet is placed inside.

[0038] In practical implementation, this utility model is used by first pressing the pressing sleeve 42 to drive the movable plate to slide on the guide inner rod 44 and squeeze the spring 45. At this time, the locking sleeve 43 disengages from the positioning groove 46. Then, the vertical plate 33 is moved left and right in the sliding groove 31 to a suitable position. After that, the pressing sleeve 42 is released, and under the elastic action of the spring 45, the locking sleeve 43 is driven to lock into the positioning groove 46 at the corresponding position, thereby dividing the box 1 into multiple storage areas. Then, the neodymium iron boron strong magnets are stored vertically separately. The vertical plate 33 is used to clamp and limit the neodymium iron boron strong magnets on both sides. Then, the rotating turntable 53 drives the screw 52 to rotate. The screw 52 drives the limiting block to slide up and down in the rectangular groove 51, thereby driving the pressure plate 54 to move downward. At this time, the pressing rod 57 that contacts the placed neodymium iron boron strong magnet slides upward on the guide inner rod 55 and squeezes the spring 56. The pressure rod 57, which does not come into contact with the NdFeB strong magnet, limits its surrounding area. Simultaneously, when the pressure plate 54 moves down to the top of the separating sleeve 37, the gradual downward movement of the pressure plate 54 causes the separating sleeve 37 to move downward within the limiting groove 34 via the limiting rod 36, compressing the spring 35. This allows for the vertical placement and storage of NdFeB strong magnets of different shapes and sizes, facilitating placement and retrieval. The NdFeB strong magnets are stably positioned when the electromagnet is not energized. When it is necessary to remove the NdFeB strong magnet, the reverse rotating turntable 53 drives the screw 52 to rotate, which in turn moves the pressure plate 54 upward. When the electromagnet 2 is energized, it generates magnetism, and the NdFeB strong magnet is pushed out due to the principle of like poles repulsion. This allows the device to classify and place NdFeB strong magnets, while facilitating the retrieval of any placed NdFeB strong magnet, thus improving the device's practicality.
