Description

Technical Field

[0001] This utility model relates to the field of magnet production equipment, specifically to a neodymium iron boron magnet magnetizing device. Background Technology

[0002] Neodymium iron boron (NdFeB) permanent magnets are widely used in motors, medical devices, and other fields due to their excellent magnetic properties. Magnetization, a key process in NdFeB magnet manufacturing, directly determines the magnet's remanence and coercivity. In existing continuous magnetization devices for NdFeB magnets, materials are sequentially fed side-by-side into a magnetization coil, which then magnetizes the materials. After magnetization, the magnets are arranged in a straight line side-by-side under magnetic attraction and then manually packaged. Since NdFeB magnets are typically packaged and sold in fixed quantities, manual packaging requires counting and then cutting the corresponding number of magnets, resulting in a large workload and low packaging efficiency. Utility Model Content

Detailed Implementation

[0020] The present invention will be further described in detail below with reference to the accompanying drawings and through embodiments. The following embodiments are explanations of the present invention, but the present invention is not limited to the following embodiments.

[0021] See Figures 1-5 This embodiment provides a neodymium iron boron magnet magnetizing device, which includes a feeding mechanism 1, a magnetizing mechanism 2, and a discharging mechanism 3. The feeding mechanism 1 is located on the left side of the magnetizing mechanism 2 and feeds the material 5 into the magnetizing mechanism 2 in a left-right parallel manner. A magnetic field is formed inside the magnetizing mechanism 2. The discharging mechanism 3 is located on the right side of the magnetizing mechanism 2 and is used to cut a fixed amount of material 5.

[0022] This invention uses a feeding mechanism 1 to place materials 5 side by side and drive them to move from left to right. The materials 5 enter the magnetization mechanism 2 and are magnetized under the influence of the magnetic field within the magnetization mechanism 2, making the materials 5 magnetic and causing adjacent materials 5 to magnetically attract each other. The materials 5 are output from the right side of the magnetization mechanism 2 into the unloading mechanism 3, which cuts a fixed amount of materials 5 for output, thereby solving the problem of needing to count manually, reducing the workload of manual packaging, and improving the efficiency of magnetic packaging.

[0023] See Figures 2-4 The feeding mechanism 3 includes a support platform 31, a cutting plate 32, and a first cylinder 33. The support platform 31 is elongated and is located on the right side of the magnetizing mechanism 2. A fixed frame 34 is provided on the upper side of the support platform 31. A movable plate 35 is provided between the fixed frame 34 and the support platform 31. The cutting plate 32 is fixed vertically on the lower side of the movable plate 35. The first cylinder 33 is provided on the fixed frame 34 and drives the movable plate 35 to move up and down.

[0024] The material 5 output from the magnetization mechanism 2 moves side by side to the support platform 31. The support platform 31 supports the material 5. When the material 5 on the right side of the cutting plate 32 reaches the required quantity, the first cylinder 33 is activated to drive the movable plate 35 to move downward, and at the same time, it drives the cutting plate 32 to move downward. The cutting plate 32 inserts between two adjacent materials 5 to separate them. At this time, the worker takes away the material 5 on the right side of the cutting plate 32 for packaging, thereby achieving the purpose of quantitatively cutting the material 5.

[0025] See Figure 3 A push switch 36 for controlling the operation of the first cylinder 33 is provided on the right end of the support platform 31.

[0026] In this invention, the first cylinder 33 is a single-acting cylinder with a built-in spring. When the press switch 36 is closed, the air source is activated to fill the first cylinder 33 with air, which drives the movable plate 35 to move downward. When the press switch 36 is opened, the air source is closed, and the first cylinder 33 can be reset under the action of the spring, which drives the movable plate 35 to move upward, thereby achieving the purpose of controlling the reciprocating motion of the first cylinder 33 by pressing the switch 36.

[0027] As material 5 moves continuously to the right under the action of feeding mechanism 1, the rightmost material 5 presses against the push switch 36, causing the push switch 36 to close and activate the first cylinder 33. The first cylinder 33 drives the cutting plate 32 to move downwards to cut a fixed amount of material 5. After the cut material 5 is removed from the support platform 31, the push switch 36 resets, and the first cylinder 33 resets to drive the cutting plate 32 to move upwards, ensuring that the material 5 on the support platform 31 can continue to move to the right. Since the position of the push switch 36 is fixed, the amount of material 5 cut by the cutting plate 32 each time can remain constant after the position of the cutting plate 32 is fixed, thus achieving the purpose of continuously and quantitatively cutting material 5.

[0028] See Figure 3 The lower side of the movable plate 35 is provided with a sliding groove 37, and the cutting plate 32 is slidably disposed in the sliding groove 37. A hand-tightening bolt 38 is provided in the sliding groove 37, and the hand-tightening bolt 38 is threadedly connected to the cutting plate 32.

[0029] By turning the hand-tightening bolt 38, the cutting plate 32 is moved left and right, thereby adjusting and fixing its left and right position. This allows for adjustment of the amount of material 5 cut each time according to different packaging needs, thus improving the applicability of this utility model.

[0030] See Figure 4 A second cylinder 39 is fixed to the right side of the cutting plate 32. The second cylinder 39 pushes the material 5 forward. An inclined guide plate 40 is provided on the front side of the support platform 31.

[0031] In this invention, the second cylinder 39 is also a single-acting cylinder with a built-in spring. When the material 5 drives the pressing switch 36 to close, the air source is activated to inflate the first cylinder 33 and the second cylinder 39. By pre-setting the front and rear positions of the second cylinder 39, the first cylinder 33 drives the cutting plate 32 to insert into the material 5. At the same time, the second cylinder 39 moves to the rear side of the material 5. Then, the second cylinder 39 pushes the material 5 forward and rolls it down along the guide plate 40 to the lower end of the guide plate 40, thus realizing the automatic feeding of the material 5 and improving the packaging efficiency of the material 5.

[0032] See Figure 4 The cutting plate 32 has a limiting member 41 fixed on its left side, and the lower side of the limiting member 41 has a limiting groove 42 that matches the shape of the material 5.

[0033] Because the magnetized materials 5 have a magnetic attraction, when the second cylinder 39 pushes the material 5 on the right side of the cutting plate 32 forward, the material 5 on the left side of the cutting plate 32 will deflect forward due to the magnetic attraction, which may cause the material 5 on the left side of the cutting plate 32 to fall off the support table 31. Therefore, in this utility model, by setting a limiting member 41 on the left side of the cutting plate 32, when the cutting plate 32 is inserted downward into the adjacent material 5, the limiting member 41 can cover the material 5 on the left side of the cutting plate 32, and the material 5 is located in the limiting groove 42 and cannot move forward, thereby preventing the material 5 on the left side of the cutting plate 32 from deflecting forward and falling off the support table 31.

[0034] See Figure 1 , Figure 2 , Figure 5 The feeding mechanism 1 includes a vibratory plate 11, a guide member 12, and a third cylinder 13. The guide member 12 is provided with a guide hole 14 that is inclined and gradually decreases in width. The upper end of the guide hole 14 is connected to the outlet of the vibratory plate 11. The lower end of the guide hole 14 is provided with a horizontal track 15. The track 15 passes through the magnetization mechanism 2 and is connected to the support platform 31. A push rod 16 is fixed on the telescopic rod of the third cylinder 13. The push rod 16 is located on the left side of the track 15.

[0035] Material 5 is placed in batches into vibratory feeder 11. Under the action of vibratory feeder 11, material 5 is placed horizontally into the upper end of guide hole 14, improving the convenience of batch feeding. Material 5 is converted into a vertical state under its own weight and the action of guide hole 14 and output from the lower end of guide hole 14 and placed on track 15. Then, under the reciprocating pushing action of third cylinder 13, adjacent materials 5 are brought together left and right and moved to the right, realizing the conveying function of feeding mechanism 1 for material 5.

[0036] The above description in this specification is merely illustrative of the present invention. Those skilled in the art to which this invention pertains may make various modifications or additions to the described specific embodiments or use similar methods to replace them, as long as they do not depart from the content of this specification or exceed the scope defined in the claims, all of which shall fall within the protection scope of this invention.
