[0002] Magnets are widely used in the field of industrial electronic products, and are used in electronics, power machinery, medical equipment, toys, packaging, hardware machinery, aerospace and other fields. The more common ones are permanent magnet motors, speakers, magnetic separators, computer disk drives, magnetic resonance imaging equipment and instruments, etc. However, before the material is subjected to magnetic detection or assembled into a device with a certain function, it needs to be magnetized in a magnetizer to have magnetism. The production of magnets includes powder making, molding, curing, grinding, coating, magnetizing, etc. The magnets are processed and used to magnetize the magnetic material or increase the magnetism of the magnets with insufficient magnetism. Generally, the magnetic object to be magnetized is placed in the magnetic field formed by the coil through which direct current passes. Neodymium iron boron magnets are the most powerful permanent magnets in contemporary times. They not only have the advantages of high remanence, high coercivity, high magnetic energy product, and high cost performance, but are also easy to process into various sizes. They are particularly suitable for electronic products with various performances, miniaturization, and lightness. However, neodymium iron boron magnets are magnetized when they leave the factory. After magnetization, the magnets need to be arranged and packaged. During packaging, the magnets cannot touch each other, otherwise they will be attracted and difficult to separate. Gaskets are needed to separate adjacent magnets. Therefore, in actual operation, the magnets and gaskets are often arranged at intervals before magnetization. However, the current arrangement and sorting are all manual operations. The magnetized NdFeB magnets are magnetic and thus adsorbed together, making the loading and unloading process time-consuming and labor-intensive, affecting processing efficiency, time-consuming and labor-intensive, and not conducive to large-scale production.

DETAILED DESCRIPTION

[0020] The following is a further detailed description of the implementation of the utility model in conjunction with the accompanying drawings and examples. The following examples are used to illustrate the utility model, but cannot be used to limit the scope of the utility model. All other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0021] Combination Figure 1 , Figure 2 and Figure 3As shown, a magnetizing device for NdFeB magnets includes a workbench 1, on which a feeding mechanism 2, a labeling mechanism 3, a magnetizing chamber 4 and a feeding mechanism 5 are arranged; the feeding mechanism 2 is used to arrange the unmagnetized NdFeB magnets in a straight line; the labeling mechanism 3 is used to mark the positive and negative poles of the magnets on the unmagnetized NdFeB magnets; the magnetizing chamber 4 is used to magnetize the unmagnetized NdFeB magnets with the positive and negative poles marked; the feeding mechanism 5 is used to arrange the magnetized NdFeB magnets in a certain number for easy storage. Specifically, the magnetizing device for NdFeB magnets is well designed, and through the coordinated work of various mechanisms, the magnetizing process of the magnets can be efficiently completed. First, the main task of the feeding mechanism 2 is to arrange the unmagnetized NdFeB magnets in a straight line for subsequent processing operations. This may require the use of a robotic arm, a conveyor belt or other automated equipment to ensure that the magnets move in a predetermined direction and sequence. Next, the function of the labeling mechanism 3 is to mark the positive and negative poles on the magnet. This helps to correctly apply the magnetic field to the corresponding poles of the magnet in the subsequent magnetization process. Labeling can be achieved by printing equipment, pasting machinery or laser engraving, etc., to ensure that each magnet is accurately marked with positive and negative poles. Then, the magnetization chamber 4 is the core part of the device, which is responsible for magnetizing the magnets marked with positive and negative poles. The magnetization chamber 4 may contain a strong magnetic field generating device, such as an electromagnet or a permanent magnet, and a system for accurately controlling the direction and intensity of the magnetic field. During the magnetization process, it is necessary to ensure that the positive and negative poles of the magnet match the magnetic field direction of the magnetization chamber 4 to achieve the best magnetization effect. Finally, the task of the unloading mechanism 5 is to arrange the magnetized magnets in a certain number for easy storage. This may require the use of equipment such as conveyor belts, robotic arms or automatic stacking machines to arrange the magnetized magnets in a preset quantity and order for subsequent use or storage. The design of the entire magnetization device not only improves production efficiency, but also ensures the accuracy and consistency of the magnetization process. At the same time, the use of automated equipment reduces the complexity and error rate of manual operations and improves production safety. This device has important application value for enterprises that mass-produce NdFeB magnets.

[0022] Combination Figure 2 , Figure 3 and Figure 4As shown, the feeding mechanism 2 includes a vibration plate 2a installed on the workbench 1, a conveying trough 2b is provided at the outlet of the vibration plate 2a, a cylinder 2c is installed at one end of the conveying trough 2b, and the output end of the cylinder 2c is consistent with the transmission direction of the conveying trough 2b. Specifically, the design of the known feeding mechanism 2 includes a vibration plate 2a, a conveying trough 2b and a cylinder 2c. This design helps to efficiently and accurately transport the unmagnetized NdFeB magnets from the vibration plate 2a to the subsequent processing links. The vibration plate 2a is a commonly used automatic feeding device, which uses the vibration principle to arrange the scattered magnets neatly and feed them into the conveying trough 2b one by one. The vibration plate 2a has the function of adjusting the amplitude and vibration frequency to adapt to magnets of different shapes and sizes, ensuring that they can enter the conveying trough 2b stably and orderly. The conveying trough 2b is a guide structure, which is designed so that the magnets coming out of the vibration plate 2a can be transmitted in a predetermined direction. A cylinder 2c is installed at one end of the conveying trough 2b, and the output end of the cylinder 2c is consistent with the transmission direction of the conveying trough 2b. The cylinder 2c is a pneumatic actuator that can quickly extend or retract after receiving a control signal, thereby pushing the magnet to move in the conveying slot 2b. The addition of the cylinder 2c makes the entire feeding process more flexible and controllable. By precisely controlling the movement of the cylinder 2c, it can be ensured that each magnet can be accurately pushed to the specified position, ready for subsequent labeling, magnetization and other operations. The design of this feeding mechanism 2 not only improves production efficiency, but also reduces the difficulty and error rate of manual operation. At the same time, due to the use of automated equipment, it can also reduce labor costs to a certain extent and improve the economic benefits of the enterprise.

[0023] Combination Figure 2 , Figure 3 and Figure 4As shown, the labeling mechanism 3 includes a mounting frame 3a installed above the conveying trough 2b, a servo motor 3b is arranged on the top of the mounting frame 3a, and a marker 3c is fixedly connected to the output end of the servo motor 3b, and the tip of the marker 3c is directly opposite to the midline position of the conveying trough 2b. Specifically, the design of the labeling mechanism 3 is very sophisticated, which can ensure that the positive and negative poles are accurately marked on the unmagnetized NdFeB magnet. Specifically, this mechanism includes several key parts such as the mounting frame 3a, the servo motor 3b and the marker 3c. The mounting frame 3a is firmly mounted above the conveying trough 2b, providing a stable support platform for the servo motor 3b and the marker 3c. Such a design ensures the stability and accuracy of the entire labeling process. The servo motor 3b is fixed on the top of the mounting frame 3a as a power source. The servo motor 3b has the characteristics of high precision and high response speed, and can quickly and accurately drive the marker 3c to act after receiving the command of the control system. The marker pen 3c is fixedly connected to the output end of the servo motor 3b in some way, so that the rotational motion of the servo motor 3b can be converted into the linear motion of the marker pen 3c. The tip of the marker pen 3c is accurately aligned with the center line position of the conveying slot 2b, which means that when the magnet moves in the conveying slot 2b, the marker pen 3c can mark the positive and negative poles in the correct position. During the labeling process, when the unmagnetized NdFeB magnet is transmitted to the bottom of the marker pen 3c, the servo motor 3b will drive the marker pen to quickly and accurately mark the positive and negative poles on the magnet. This process is automated, which not only improves production efficiency, but also greatly reduces the possibility of human error. In general, the design of this labeling mechanism 3 is simple and efficient, which can ensure that each NdFeB magnet is correctly marked with positive and negative poles, providing important guarantees for the subsequent magnetization process.

[0024] Combination Figure 1 , Figure 2 and Figure 3As shown, the magnetizing chamber 4 is a semi-cylindrical cover arranged above the conveying trough 2b. Specifically, the magnetizing chamber 4 is designed to be semi-cylindrical and is covered above the conveying trough 2b. This structure is not only conducive to the concentration and stability of the magnetic field, but also provides a good environment for the magnetizing process of the magnet. The semi-cylindrical magnetizing chamber 4 can effectively confine the magnetic field in a smaller space, making the magnetic field intensity higher and more uniform. This is crucial for the magnetizing process of the NdFeB magnet, because a uniform magnetic field can ensure that the magnet is uniformly magnetized, thereby improving the magnetic properties of the magnet. In addition, the magnetizing chamber 4 is covered above the conveying trough 2b, which can ensure that during the magnetizing process, the magnet can stably move in the conveying trough 2b without being disturbed or offset by the magnetic field. This design not only improves the accuracy of magnetization, but also ensures the continuity of the production process. In addition, the magnetizing chamber 4 may also be equipped with a magnetic field generating device (such as an electromagnet or a permanent magnet) and a control system for generating and controlling the magnetic field. These devices are usually integrated in the magnetizing chamber 4 to ensure that the magnetic field can accurately act on the magnet and achieve an efficient magnetizing process. In general, the design of the semi-cylindrical magnetizing chamber 4, which is covered above the conveying trough 2b, not only takes into account the uniformity and stability of the magnetic field, but also ensures the stability and continuity of the magnet during the magnetizing process. It is a very practical and efficient magnetizing device structure.

[0025] Combination Figure 2 , Figure 3 and Figure 4As shown, the unloading mechanism 5 includes an electric push rod 5a and a unloading trough 5b arranged perpendicularly to the outlet of the magnetizing chamber 4, and the pushing direction of the output end of the electric push rod 5a is consistent with the discharging direction of the unloading trough 5b. Specifically, the design of the unloading mechanism 5 fully considers the arrangement and storage requirements of the NdFeB magnets after magnetization. Through the coordinated use of the electric push rod 5a and the unloading trough 5b, the mechanism can efficiently arrange and arrange the magnetized magnets according to a certain number, which is convenient for subsequent storage or further processing. The electric push rod 5a is arranged perpendicularly to the outlet of the magnetizing chamber 4, and the pushing direction of its output end is consistent with the discharging direction of the unloading trough 5b. This design ensures that when the magnetized magnets are removed from the outlet of the magnetizing chamber 4, the electric push rod 5a can accurately push them into the unloading trough 5b. The electric push rod 5a has the ability to accurately control the pushing distance and speed, so the number and interval of the pushed magnets can be adjusted as needed. The design of the unloading trough 5b also takes into account the neat arrangement and convenient storage of the magnets. The inside of the trough body may be provided with a slide rail or a guide structure to ensure that the magnet can maintain a stable arrangement state in the trough. At the same time, the discharge port of the feed trough 5b can be docked with a storage container or a conveyor belt and other equipment to realize the automatic storage or transportation of the magnet. Through the operation of the feed mechanism 5, the magnetized NdFeB magnets can be neatly arranged in the feed trough 5b according to a predetermined quantity and order, which greatly improves production efficiency and product quality. At the same time, this automated feed method also reduces the complexity and error rate of manual operation, saving labor costs for the enterprise. In general, the design of the feed mechanism 5 is both practical and efficient, and provides a perfect finishing link for the magnetization production line of NdFeB magnets.

[0026] Combination Figure 3 , Figure 4 and Figure 5As shown, the unloading mechanism 5 also includes an adjustable limiting mechanism 6 arranged away from the exit of the magnetizing chamber 4, and the limiting mechanism 6 is used to limit the length of the NdFeB magnet after magnetization. Specifically, the adjustable limiting mechanism 6 added to the unloading mechanism 5 is a very clever and practical design, which is mainly used to limit the length of the NdFeB magnet after magnetization, ensuring that the magnet can reach the predetermined quantity and length requirements when it is stored or further processed. The limiting mechanism 6 is usually arranged away from the exit of the magnetizing chamber 4, that is, at a suitable position of the unloading trough 5b. This design can ensure that after the magnet passes through the magnetizing chamber 4 and completes magnetization, and then is pushed by the electric push rod 5a, when it finally reaches the limiting mechanism 6, its length can be accurately controlled. The design of the limiting mechanism 6 is adjustable, which means that the operator can adjust the position or limiting force of the limiting mechanism 6 according to actual needs to adapt to the processing requirements of magnets of different lengths or quantities. This flexibility makes the entire unloading mechanism 5 more versatile and efficient. In actual work, when the magnetized NdFeB magnet is pushed to the limit mechanism 6, the limit mechanism 6 will play its role and limit the continued movement of the magnet, thereby ensuring that the length of the magnet meets the preset requirements. Subsequently, the electric push rod 5a starts to push the NdFeB magnet of a certain length into the feeding trough 5b, and the operator can easily remove the sorted magnets for subsequent storage or processing operations. In general, the addition of the adjustable limit mechanism 6 not only enhances the practicality and flexibility of the feeding mechanism 5, but also improves the automation and work efficiency of the entire magnetization production line.

[0027] Combination Figure 3 , Figure 4 and Figure 5As shown, the limiting mechanism 6 includes a limiting block 6a installed on the workbench 1, a slider 6a1 is provided at the bottom of the limiting block 6a, a chute 1a is provided on the workbench 1, and the slider 6a1 is slidably connected with the chute 1a. Specifically, the design of the limiting mechanism 6 is detailed and practical, mainly including a limiting block 6a installed on the workbench 1, and a sliding connection between the slider 6a1 at the bottom of the limiting block 6a and the chute 1a on the workbench. This design enables the limiting mechanism 6 to flexibly adjust the position to adapt to NdFeB magnets of different lengths. As a component that directly limits the length of the magnet, the accuracy and stability of the position of the limiting block 6a are crucial. By installing the limiting block 6a on the workbench 1, its stability during the working process can be ensured. At the same time, the shape and size of the limiting block 6a are also carefully designed to ensure that it can effectively limit the movement of the magnet. The sliding connection between the slider 6a1 and the chute 1a is the key to the position adjustment of the limiting mechanism 6. The slider 6a1 is designed at the bottom of the limit block 6a so that it can slide smoothly along the slide 1a. The slide 1a is set on the workbench 1, and its length and position are reasonably planned according to the size and layout of the workbench 1 to meet the needs of the limit mechanism 6 at different positions. In actual use, the operator can adjust its position by sliding the limit block 6a as needed. When it is necessary to process magnets of different lengths, it is only necessary to slide the limit block 6a to the corresponding position to achieve accurate control of the length of the magnet. This design not only improves work efficiency, but also reduces the difficulty of operation, making the entire magnetization process more convenient and efficient. In general, this design of the limit mechanism 6 with a sliding connection not only ensures the realization of the limit function, but also provides flexible adjustment capabilities, which brings great convenience and benefits to the magnetization production line of NdFeB magnets.

[0028] Combination Figure 3 , Figure 4 and Figure 5As shown, the slider 6a1 is provided with a fixing bolt 6a2. Specifically, the fixing bolt 6a2 is provided on the slider 6a1, which is an important design detail, and it greatly enhances the stability and practicality of the limit mechanism 6. The function of the fixing bolt 6a2 is that when the limit block 6a slides to a suitable position in the slide slot 1a through the slider 6a1, the limit block 6a can be fixed at the current position by tightening the fixing bolt 6a2. In this way, even if vibration or impact occurs during the magnetization process, the limit block 6a will not be easily displaced, thereby ensuring the accuracy and stability of the magnet length limitation. The design of the fixing bolt 6a2 also takes into account the convenience of operation. It is usually located in an easily accessible position of the slider 6a1 and is equipped with a suitable operating handle or knob, so that the operator can easily tighten or loosen the bolt to achieve rapid fixation and adjustment of the limit block 6a. In addition, the material and manufacturing process of the fixing bolt 6a2 are also carefully selected to ensure that it has sufficient strength and durability, and can maintain stable performance during long-term use. In general, by arranging the fixing bolt 6a2 on the slider 6a1, not only the stability and reliability of the limiting mechanism 6 are improved, but also the entire magnetization process is made more efficient and safer. This design detail fully reflects the ingenuity and practicality of the device design.
