Description

Technical Field

[0001] This utility model relates to the field of neodymium iron boron processing technology, and in particular to a neodymium iron boron magnetizing and pushing mechanism. Background Technology

[0002] In the production process of NdFeB magnetic materials, magnetization is a crucial step, and its quality directly affects the magnetic properties and performance of the final product. Traditional magnetization equipment typically uses manual or semi-automatic methods for material arrangement and conveying, which suffers from low efficiency, inaccurate material arrangement, and easy material adsorption. Especially when magnetizing multiple NdFeB materials continuously, mutual adsorption can easily occur due to the close proximity of the materials, affecting the uniformity of magnetization and product consistency.

[0003] Furthermore, in actual production, to prevent NdFeB magnets from adsorbing during the magnetization process, non-magnetic spacers are usually inserted between them to ensure that each magnet can complete the magnetization process independently. However, existing feeding mechanisms often struggle to achieve an orderly staggered arrangement of NdFeB magnets and spacers, complicating subsequent magnetization processes and reducing automation levels and production efficiency. Utility Model Content

A magnetizing device is provided near one end of the conveyor belt, and a pushing component is installed on the conveyor belt section near the magnetizing device. The pushing component can arrange the NdFeB and spacers into a single straight line in an alternating manner, so that the NdFeB and spacers can smoothly enter the magnetizing device for processing.

[0014] This utility model provides a neodymium iron boron magnetizing and pushing mechanism, which, compared with the prior art, has the following advantages:

[0015] 1. This utility model uses cylinders two and three to drive pusher plates one and two downwards, respectively. Combined with real-time detection of the positions of NdFeB and spacers by sensors, it achieves precise blocking and pushing of materials. This structure ensures that the NdFeB and spacers enter the linear conveying area limited by guide rods in sequence and are arranged alternately according to a set order, effectively avoiding adsorption of NdFeB due to proximity during magnetization, thereby improving the stability of the magnetization operation and product quality.

[0016] 2. This utility model achieves flexible guidance and precise positioning of NdFeB iron boron and partitions entering the conveying channel by setting a linkage structure of a fixing block, spring, and inclined plate inside the limiting plate. The inclined plate can automatically tilt outward under the action of the spring, and guide the material accurately into the preset straight conveying path in conjunction with the guide rod, ensuring orderly conveying of both and further improving the discharge accuracy and the reliability of equipment operation.

[0028] The following detailed description, in conjunction with the accompanying drawings, outlines some embodiments of the present invention. Unless otherwise specified, the following embodiments and features can be combined with each other.

[0029] Please refer to Figures 1-8 This utility model provides a neodymium iron boron magnetizing and pushing mechanism, including a conveyor belt 1, on which two sets of symmetrically arranged limiting plates 2 are provided. The limiting plates 2 are detachably fixed to the frame of the conveyor belt 1 by bolts, thereby forming a channel for material conveying between the two sets of limiting plates 2.

[0030] A middle plate 3 is provided in the middle of the conveying channel. The middle plate 3 is connected and fixed to the limiting plate 2 by a screw, dividing the conveying channel into two independent areas, which are used to separately convey neodymium iron boron material and spacers.

[0031] Furthermore, a certain gap is left between the bottom of the limiting plate 2 and the middle plate 3 and the upper surface of the conveyor belt 1 to reduce friction and facilitate cleaning and maintenance.

[0032] To improve the smoothness of the feeding process, a slant bar 6 is provided at the feeding end of the limit plate 2 to guide the material into the conveying channel.

[0033] A magnetizing device is installed near one end of the conveyor belt 1 to magnetize the arranged neodymium iron borons. A pushing assembly is installed above the conveyor belt 1 at this end. The pushing assembly can arrange the neodymium iron borons and spacers in a set order and organize them into a straight line so that they enter the magnetizing device for processing in sequence.

[0034] The core components of the magnetization device include one or more magnetic pole heads made of highly permeable magnetic material and a magnetization coil wound around them. When current passes through the magnetization coil, a high-intensity transient magnetic field is formed between the magnetic pole heads. The direction of this magnetic field is aligned with the axis of the neodymium iron boron magnet to be magnetized. During the magnetization process, the neodymium iron boron magnets, which have been arranged in a straight line and interlaced with spacers, are transported to a designated position below the magnetization device. The control system then triggers the magnetization coil to be energized, instantly generating a strong magnetic field that saturates the neodymium iron boron magnets, thereby obtaining the desired magnetic properties.

[0035] Specifically, the feeding assembly includes a bracket 8, which is fixed to the conveyor belt 1. A cylinder 9 is mounted on the bracket 8, with its piston end connected to a mounting base. Cylinders 10 and 11 are sequentially mounted on the mounting base. The piston end of cylinder 10 is connected to push plate 12, and the piston end of cylinder 11 is connected to push plate 13. Push plate 12 and push plate 13 are located in two areas of the conveying channel, with a certain gap between them to achieve step-by-step pushing and precise discharge of the NdFeB and spacers.

[0036] In order to achieve real-time monitoring of material position, sensors 17 are installed on the inner walls of the symmetrically arranged limit plates 2 to collect material arrival signals and thus control the timing of the pushing action.

[0037] In addition, an installation groove 4 is provided on the lower side of the limiting plate 2, and a fixing block 14 is installed in the groove. An inclined plate surface 15 is connected to one side of the fixing block 14 by a hinge, and a spring 16 is provided between the inclined plate surface 15 and the fixing block 14 to make the inclined plate surface 15 tilt outward and protrude to achieve flexible flow guidance.

[0038] A guide rod 5 is also provided on the inner side of the limiting plate 2, one end of which contacts the inclined plate surface 15 to guide the material into the conveying area along a preset path. The inclined plate surface 15 extends into the conveying channel through the mounting groove 4 to achieve effective guidance of the material.

[0039] Furthermore, the middle plate 3 is provided with a pointed tip 7 at one end near the discharge end. This structural design helps the material to transfer smoothly and improves the overall smoothness and stability of the operation.

[0040] In summary, the working principle of the neodymium iron boron magnetizing and pushing mechanism of this utility model embodiment is as follows: the neodymium iron boron magnet and the spacer enter two independent areas of the conveying channel from the feed port respectively. Under the guidance of the limiting plate 2 and the middle plate 3, they are conveyed forward along their respective paths. The sensor 17 installed on the inner wall of the limiting plate 2 detects the position signals of the neodymium iron boron and the spacer in real time and feeds back the positioning information to the control system, providing a basis for the next pushing action. The control system controls the cylinder 2 10 and cylinder 3 11 to move in sequence according to the signal of the sensor 17, driving the push plate 1 12 and push plate 2 13 to block or push the material downward, so that it enters the straight conveying area defined by the guide rod 5 in sequence, realizing the orderly staggered arrangement of neodymium iron boron and spacer. The inclined plate surface 15 set at the lower part of the limiting plate 2 cooperates with the spring 16 and the guide rod 5 to ensure that the material enters the designated conveying path stably.

[0041] The above are merely preferred embodiments of this utility model and are not intended to limit the scope of this utility model. Various modifications and variations can be made to this utility model by those skilled in the art. Any modifications, equivalent substitutions, or improvements made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
