Description

Technical Field

[0001] The invention relates to the technical field of magnetizing NdFeB magnetic sheets, in particular to automatic magnetizing equipment. Background Art

[0002] Neodymium iron boron magnets have the advantages of high remanence, high coercivity, high magnetic energy product, and high cost-effectiveness. They are also easy to process into various sizes, making them particularly suitable for electronic products with various performance requirements, miniaturization, and lightweightness. However, neodymium iron boron magnets need to be magnetized before they can be put into use. High-end products have very high magnetic performance requirements, requiring 100% magnetization to reach saturation, and no weak magnetic flakes are allowed. Existing magnetization technology mainly feeds materials to trays through a vibrating plate, then manually places multiple trays into the coil for pre-magnetization. After magnetization, the materials are removed, manually stacked neatly, and then sent back into the magnetization coil for saturation magnetization. However, during the manual stacking process, especially when stacking small neodymium iron boron magnets, stacking errors or improper placement of the coils are prone to occur, resulting in weak magnetization. Therefore, manual stacking and magnetization is not only inefficient but also prone to weak magnetization. In addition, most of the existing automatic magnetizing equipment directly loads the material on the vibration plate, but the small magnets are relatively light in weight, which will lead to insufficient loading capacity of the vibration plate and are easily affected by external air flow vibration and other interferences. Direct docking with the magnetizer will seriously affect the loading efficiency; the magnetization process is mostly single-coil single magnetization, or single-coil repeated magnetization, and the high current in the magnetization process will cause high heat and high loss, which is not suitable for frequent use; single-coil single magnetization cannot guarantee the magnetization saturation rate, and although the single-coil repeated magnetization reduces the generation of weak magnetism to a certain extent, the edge position magnets cannot avoid insufficient magnetization during magnetization, and it cannot be guaranteed that 100% magnetization reaches saturation; although magnetizing the magnets one by one can ensure that the magnetization saturation rate reaches 100%, the magnetization efficiency is very low and the economy is not high; therefore, there is an urgent need for an automatic magnetization equipment that can ensure the magnetization saturation rate.

[0003] The patent document (China Patent Publication No.: CN114464393A) discloses a fully automatic magnetizing device for special-shaped magnets. When magnetizing small NdFeB magnets, it adopts a two-step magnetization method. The principle of the two-step magnetization is to first use permanent magnets for magnetic guidance to pre-magnetize and then use magnetization coils for saturation magnetization. However, this method only performs saturation magnetization once. During continuous operation, if the material is arranged close to the ends of the magnetization coil during magnetization, the magnetization will still be unsaturated. Summary of the Invention

[0032] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments 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 any creative efforts shall fall within the scope of protection of the present invention.

[0033] See Figure 1 As shown, an automatic magnetizing device includes a first magnetizing device 1, the discharge end of the first magnetizing device 1 is connected to the feed end of the dividing device 2, and the discharge end of the dividing device 2 is connected to the feed end of the second magnetizing device 3. The dividing device 2 is used to collect magnetized materials with a length less than or equal to the saturation magnetization length of the second magnetizing device 3 from the discharge end of the first magnetizing device 1, and transport the collected magnetized materials to the second magnetizing device 3 for saturation magnetization.

[0034] After the material is magnetized once by the first magnetizing device 1, the material at both ends may be insufficiently magnetized. At this time, the material at both ends can be transported to the second magnetizing device 3 respectively through the material dividing device 2. Try not to let the material be placed at both ends of the second magnetizing device 3, but place it in the optimal magnetizing section of the second magnetizing device to ensure that the material that is not fully magnetized at both ends or cannot be saturated magnetized after one magnetization can be re-saturated magnetized.

[0035] The saturation magnetization length of the second magnetizing device 3 is generally shorter than the length of its optimal magnetization region, and the length of the optimal magnetization region is shorter than the length of the second magnetizing coil.

[0036] Those skilled in the art will appreciate that the length of the magnetized material collected by the material dividing device 2 after the first magnetization is shorter than the length of the second magnetization coil in the second magnetization device 3. This can increase the saturation rate of magnetization and improve magnetization efficiency by eliminating the need to use the same magnetization device for repeated magnetization.

[0037] According to the above working principle, some preferred embodiments or implementation structures are provided. Figure 5 As shown, the first magnetizing device 1 includes a first magnetizing coil 11, a first supporting mechanism 12 and a conveying track 13. The first magnetizing coil 11 is connected to the first supporting mechanism 12. The conveying track 13 has at least two first grooves 131. One end of the conveying track 13 is provided with a discharge track 14 of a vibrating disk. The discharge track 14 of the vibrating disk has a notch 141 corresponding to the first groove 131 at one end close to the conveying track 13. The width and position of the notch 141 match the width and position of the first groove 131. A first pushing device 5 is provided on the side of the notch 141 away from the first groove 131. The first pushing device 5 is used to push the material from the notch 141 into the first groove 131; the other end of the conveying track 13 passes through the first magnetizing coil 11 and is located below the material dividing device 2. In this way, when the material is output from the discharge track 14 of the vibrating disk and reaches the gap 141, the first pushing device 5 pushes the material into the first groove 131, which can redirect the conveyed material and increase the amount of material entering the first magnetizing coil 11 at one time, thereby improving the efficiency of material loading.

[0038] Preferably, see Figure 2 and Figure 5 As shown, the first pusher 5 comprises a first telescopic cylinder 51 and a first push block 52. The first push block 52 is connected to the telescopic end of the first telescopic cylinder 51, while the fixed end of the first telescopic cylinder 51 is connected to one side of the notch 141. The amount of material entering the first magnetizing coil can be calculated by counting the number of times the piston of the first telescopic cylinder 51 extends. The first telescopic cylinder 51 can be a pneumatic cylinder. By controlling the extension of the telescopic end of the first telescopic cylinder 51, i.e., its piston, the first push block 52 is driven to push the material from the notch 141 into the first groove 131.

[0039] Those skilled in the art should be able to imagine that the first telescopic cylinder 51 can also adopt a piston cylinder structure such as an electric cylinder, a hydraulic cylinder, etc., and the first pushing device 5 can also adopt a pushing structure such as a linear module.

[0040] See Figure 5 As shown, first cover plates 17 are provided at both ends of the conveying track 13. The first cover plates 17 are used to limit the passage of materials, allowing the materials to pass through in order and preventing the materials from rolling.

[0041] A first pressing plate 15 is provided above the first groove 131 and is disposed within the first magnetizing coil 11. The first pressing plate 15 is connected to a first automatic pressing mechanism 16, which is used to push the first pressing plate 15 to press the material within the first groove 131. Thus, when the material within the first groove 131 enters the first magnetizing coil 11, the first automatic pressing mechanism 16 drives the first pressing plate 15 to press the material within the first groove 131, thereby preventing the material from splashing during magnetization and preventing the front and rear materials within the first magnetizing coil 11 from affecting the magnetization.

[0042] Preferably, the first automatic pressing mechanism 16 includes a fifth telescopic cylinder 161, which is connected to the end of the first supporting mechanism 12. This can make the overall structure of the automatic magnetizing device simpler and more compact. The fifth telescopic cylinder 161 is preferably a cylinder structure, which has a fast action and high energy utilization rate.

[0043] Those skilled in the art should be able to imagine that the fifth telescopic cylinder 161 can also adopt a piston cylinder structure such as an electric cylinder, a hydraulic cylinder, etc., and the first automatic pressing mechanism 16 can also adopt a material pressing structure such as a linear module.

[0044] See Figure 3As shown, the second magnetizing device 3 includes a second magnetizing coil 31, a second supporting mechanism 32 and an automatic conveyor belt 33. One end of the automatic conveyor belt 33 is arranged below the other end of the conveying track 13, and the other end of the automatic conveyor belt 33 passes through the second magnetizing coil 31. The second magnetizing coil 31 is supported on one side of the other end of the conveying track 13 by the second supporting mechanism 32. The material dividing device 2 includes a second telescopic cylinder 21, a second top block 22 and a material receiving box 23. The second telescopic cylinder 21 is arranged on one side of one end of the automatic conveyor belt 33, and the second top block 22 is connected to the telescopic end of the second telescopic cylinder 21. The second top block 22 has a first protrusion 221 corresponding to the position and size of the first groove 131. The material receiving box 23 has a second groove 231 corresponding to the position and size of the first groove 131. The material receiving box 23 is connected to the automatic conveyor belt 33. Those skilled in the art should be able to imagine that there can be multiple material receiving boxes 23, evenly distributed on the automatic conveyor belt 33. When the material to be secondary magnetized is output from the conveyor track 13 and reaches the top of the receiving box 23, when the material extending above the second groove 231 is equal to the length of the second groove 231, the second telescopic cylinder 21 is controlled to drive the second top block 22 to cut the material and press it into the second groove 231. The material is then conveyed to the second magnetizing coil 31 via the automatic conveyor belt 33 to complete the secondary magnetization. During the secondary magnetization, the length of the second groove 231 is generally set to be less than the length of the second magnetizing coil 31. This ensures that the magnetization saturation rate of the material in the second groove 231 is guaranteed during magnetization. The automatic conveyor belt 33 can be driven by a drive motor 330 to drive the belt and the receiving box 23 to run on the guide rail 331. The position of the receiving box 23 is detected by a position sensor, and the motor speed is controlled to realize automatic conveyance of the receiving box and automatically match the speed of the first magnetization of the material.

[0045] Those skilled in the art should be able to imagine that the material dividing device 2 here can also adopt various structural forms, such as multi-degree-of-freedom robot control, or a vacuum suction cup that sucks a certain amount of material and then feeds it back to the second magnetizing device, but that will increase the cost.

[0046] A second pressing plate 34 is provided above the second groove 231 and is disposed within the second magnetizing coil 31. The second pressing plate 34 is connected to a second automatic clamping mechanism 35, which is used to push the second pressing plate 34 to compress the material within the second groove 231. This is also done to prevent any impact on the magnetized material. The second automatic clamping mechanism 35 includes a sixth telescopic cylinder 351, which is connected to the end of the second support mechanism 32. This allows for a simpler and more compact overall structure for the automatic magnetizing equipment. The sixth telescopic cylinder 351 is preferably a pneumatic cylinder structure, which allows for quick movement and high energy efficiency.

[0047] Those skilled in the art should be able to imagine that the sixth telescopic cylinder 351 can also adopt a piston cylinder structure such as an electric cylinder, a hydraulic cylinder, etc., and the second automatic pressing mechanism 35 can also adopt a material pressing structure such as a linear module.

[0048] A second cover plate 24 is disposed above the material receiving box 23 and below the second top block 22. A through slot 241 is provided on the second cover plate 24, matching the position and size of the first protrusion 221. The second cover plate 24 serves to limit the material as it is conveyed forward. The through slot 241 facilitates the passage of the second top block 22 on the second pressing plate 34. The second top block 22 matches the size of the second groove 231, pressing the material into the second groove of the material receiving box 23.

[0049] The discharge end of the second magnetizing device 3 is connected to a discharge device 4 , which is used to collect the material output from the second magnetizing device 3 .

[0050] Preferably, see Figure 4 As shown, the unloading device 4 includes a bracket 41, a third top block 42, and a collection box 43 (see Figure 1 As shown), the first linear module 44 and the second linear module 45, the lower end surface of the third top block 42 is provided with a plurality of third grooves 421, and the third top block 42 is arranged above the receiving box 23, the upper end surface of the third top block 42 is connected to the sliding end of the first linear module 44, the fixed end of the first linear module 44 is connected to the sliding end of the second linear module 45, and the fixed end of the second linear module 45 is connected to one side of the bracket 41, and the upper end surface of the bracket 41 is provided with a plurality of second protrusions 411 corresponding to the size and position of the third grooves 421, and the bracket 41 is arranged on the other end side of the automatic conveyor belt 33, refer to Figure 1 The material collecting box 43 is shown to be arranged on one side of the bracket 41 ; preferably, a material guide plate 46 is provided between the material collecting box 43 and the upper end surface of the bracket 41 ; the material guide plate 46 is connected to the bracket 41 .

[0051] See Figure 1 and Figure 3 As shown, after the material has completed the second magnetization, it is transported to the top of the collecting box 43 through the automatic conveyor belt 33, and the first linear module 44 and the second linear module 45 are controlled to drive the third top block 42 to absorb the magnetized material from the receiving box 23, and then push the material to pass through the second protrusion 411 for scraping, and then fall into the collecting box 43. Under the action of the automatic conveyor belt 33, the receiving box 23 continues to return to the bottom of the conveying track to complete the next round of material receiving operation.

[0052] See Figure 4As shown, the first linear module 44 includes a third telescopic cylinder 441, and the second linear module 45 includes a fourth telescopic cylinder 451. Preferably, the third telescopic cylinder 441 and the fourth telescopic cylinder 451 are pneumatic cylinder structures. Those skilled in the art will appreciate that the first linear module 44 and the second linear module may also utilize a ball screw linear module, a screw jacking structure, or a rack and pinion linear module. The telescopic cylinders are preferably pneumatic cylinder structures, as this minimizes the impact on the movement of the magnetized material. Of course, other structures contemplated by those skilled in the art may also be employed.

[0053] For specific usage, see Figures 1 to 5 As shown, the double-coil automatic magnetizing equipment of the present invention continuously and neatly loads small and disorderly NdFeB magnets through the vibrating disk in the loading device until it is pushed by the first telescopic cylinder 51 arranged perpendicular to the discharge direction of the vibrating disk in the conveying track 13, and the magnets are redirected from single-strip loading on the vibrating disk to multiple-strip loading in the conveying track 13 through the conveying track 13, and are continuously pushed by the first telescopic cylinder 51 to the conveying track 13 in the first magnetizing device. The first telescopic cylinder 51 pushes the counting. When the number of magnets in the first magnetizing coil reaches the specified number, the front and rear fifth telescopic cylinders 161 drive the first pressing plate 15 to press the magnet downward, and then the first magnetizing coil is instantly discharged to magnetize the magnet. After the discharge is completed, the fifth telescopic cylinder 161 drives the first pressing plate 15 to retract, and the first telescopic cylinder 51 continues to push the magnet forward to the second groove 231 of the receiving box 23. When the length of the magnet reaches the length of the multiple-segment groove in the second groove 231, the second telescopic cylinder 21 drives the cutting head downward to cut off the continuous After the cutting is completed, the second telescopic cylinder 21 retracts, and the receiving box 23 is driven by the belt driven by the driving motor to reach the inside of the second magnetizing coil 31. Because the length of the receiving box 23 is less than the length of the second magnetizing coil 31, the receiving box 23 can completely enter the middle of the second magnetizing coil 31. At this time, the front and rear sixth telescopic cylinders 351 drive the second pressing plate 34 to press the magnet in the second groove 231 downward, and the second magnetizing coil 31 is instantly discharged for secondary magnetization of the magnet. After the discharge is completed, the sixth telescopic cylinder 35 1 retracts, the receiving box 23 carries the secondary magnetized magnet to the unloading position, and then the third telescopic cylinder 441 above the unloading position drives the third top block 42 to absorb the magnetized magnet downward and retract. After absorption, the receiving box 23 returns to the starting position to start the next cycle. At this time, the fourth telescopic cylinder 451 pushes the third telescopic cylinder 441 forward to pass through the second protrusion 411. The second protrusion 411 scrapes the magnet off the third top block 42 and buffers it into the collecting box 43 through the guide plate 46, completing the collection of the magnetized magnet.
