Description

Technical Field

[0001] The utility model belongs to the technical field of magnet processing, and in particular relates to a pre-magnetization device for processing neodymium iron boron magnets. Background Art

[0002] NdFeB is a kind of magnet. It is different from the magnets we usually see. It has strong magnetic properties, so it is called the "king of magnets". NdFeB magnetic materials are alloys of neodymium, iron oxide, etc., with extremely high magnetic energy product and intrinsic coercive force, and at the same time have the advantages of high energy density, which makes NdFeB permanent magnet materials widely used in modern industry and electronic technology. The application of NdFeB permanent magnet materials has made electroacoustic motors, instruments and meters, magnetization equipment, etc. have miniaturization, lightness, and thinness improvements. NdFeB is divided into bonded NdFeB and sintered NdFeB. Bonded NdFeB is magnetic in all directions and corrosion-resistant; sintered NdFeB is easy to corrode, so the surface needs to be coated, generally with zinc, nickel, epoxy resin, etc. Sintered NdFeB is generally divided into axial magnetization and radial magnetization, and the magnetization direction is determined according to the working surface required for production.

[0003] The traditional magnetizing process is: code the NdFeB products one by one. The inkjet printer is an independent inkjet printer and needs to be transferred. It is necessary to manually identify the NS pole identification direction of the product, and arrange them one by one. The identification direction must be consistent. Then design a tooling, put the stacked and arranged products into the tooling one by one (or wrap them with paper) and then magnetize them. Put the tooling containing the products into the magnetizer for saturation magnetization. There are gaps when the products are stacked and arranged, and collisions will occur during magnetization, which is easy to cause edge knocking and affect product quality. The magnetizing power supply is set in the magnetizing coil, and the pulse magnetic field is used for magnetization. The original magnetizing power supply needs to charge the capacitor, and then pulse discharge magnetization, which will be more power-consuming. The existing magnetizing technology has low production efficiency, manual operation is more prone to errors and omissions, and the identification direction is easy to be wrong. It is not only time-consuming and labor-intensive, but also inefficient. Utility Model Content

DETAILED DESCRIPTION

[0022] 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.

[0023] Combination Figure 1 , Figure 2 , Figure 3 and Figure 4As shown, a pre-magnetization device for processing NdFeB magnets includes a workbench 1, a conveying trough 2 is arranged on the workbench 1, and a blank feeding mechanism 3, a spacer feeding mechanism 4 and a sorting mechanism 5 are arranged on the conveying trough 2; the blank feeding mechanism 3 is used to place the NdFeB blank on the conveying trough 2 along the travel direction of the conveying trough 2; the spacer feeding mechanism 4 is used to place the spacer between two adjacent NdFeB blanks on the conveying trough 2; the sorting mechanism 5 is used to sort the NdFeB blanks and spacers on the conveying trough 2 to form a whole; when the NdFeB blank needs to be magnetized, the blank feeding mechanism 3 places the NdFeB blank on the conveying trough 2 along the travel direction of the conveying trough 2, and at the same time, the spacer feeding mechanism 4 places the spacer between two adjacent NdFeB blanks on the conveying trough 2, and at this time, the sorting mechanism 5 sorts the NdFeB blanks and spacers on the conveying trough 2 into a whole, and after the sorting is completed, it is transported to the next process through the conveying trough 2. Specifically, the design of the pre-magnetization device for NdFeB magnet processing is very clever, and it can efficiently complete the preparatory work before pre-magnetization of NdFeB blanks. The workbench 1 serves as the foundation and support of the entire device, and the workbench 1 provides a stable working environment. Its design should take into account the stability of the overall structure and the convenience of operation. The conveying trough 2 is located on the workbench 1, which is used to carry and guide the NdFeB blanks and spacers. Its design should ensure that the blanks and spacers can move smoothly and accurately along the predetermined path. The blank feeding mechanism 3 is responsible for placing the NdFeB blanks on the conveying trough 2 according to the predetermined spacing and direction. It may use a mechanical arm, a vibrating plate or other automated feeding methods to improve production efficiency and reduce manual intervention. The spacer feeding mechanism 4 is responsible for placing spacers between adjacent NdFeB blanks. The role of the spacer may be to maintain the spacing between the blanks to prevent adhesion or mutual interference during the subsequent magnetization process. The sorting mechanism 5 works after the blanks and spacers are placed, and its main function is to sort them into a compact and orderly whole. This helps to ensure that each blank is evenly and effectively affected by the magnetic field during the subsequent magnetization process. The entire workflow is very smooth: the blank feeding mechanism 3 first places the blank on the conveying trough 2, and then the spacer feeding mechanism 4 places spacers between adjacent blanks, and then the sorting mechanism 5 sorts them to form a whole. Finally, the sorted blanks and spacers are transported to the next process, namely the magnetization process, through the conveying trough 2. The design of this pre-magnetization device fully considers the requirements of production efficiency and product quality. Through automation and precise control, it realizes efficient and accurate processing of NdFeB blanks, laying a solid foundation for the subsequent magnetization process.

[0024] Combination Figure 1 , Figure 3 , Figure 5 and Figure 6As shown, the arranging mechanism 5 includes a mounting frame 51 mounted on the conveying trough 2, a first cylinder 52 is arranged on the mounting frame 51, and a flattening plate 53 is fixedly connected to the output end of the first cylinder 52. Specifically, the arranging mechanism 5 plays a vital role in the pre-magnetization device. It is responsible for arranging the NdFeB blanks and the spacers into a compact and orderly whole to ensure that each blank can be evenly and effectively affected by the magnetic field during the subsequent magnetization process. The arranging mechanism 5 is mainly composed of a mounting frame 51, a first cylinder 52 and a flattening plate 53. The mounting frame 51 is the basis of the arranging mechanism 5. It is firmly mounted on the conveying trough 2 and is used to support and fix other components. The design of the mounting frame 51 should take into account the stability of the overall structure and the convenience of operation to ensure that the arranging mechanism 5 can operate smoothly and accurately. The first cylinder 52 is the power source of the arranging mechanism 5, which is mounted on the mounting frame 51. By controlling the extension and contraction of the first cylinder 52, the flattening plate 53 can be driven to move up and down or forward and backward. The selection of the first cylinder 52 should be determined according to actual needs and working environment to ensure that it has sufficient driving force and stability. The flattening plate 53 is a key component of the sorting mechanism 5, which is fixedly connected to the output end of the first cylinder 52. When the first cylinder 52 drives the flattening plate 53 to move, the flattening plate 53 can sort and compact the NdFeB blanks and spacers on the conveying trough 2. The design of the flattening plate 53 should take into account the contact area and friction with the blanks and spacers to ensure that the sorting effect is good and does not damage the material. In actual work, when the NdFeB blanks and spacers are placed on the conveying trough 2, the sorting mechanism 5 starts to work. The first cylinder 52 drives the flattening plate 53 to move downward to compact and sort the blanks and spacers. The design of the flattening plate 53 should ensure that it can cover the width of the entire conveying trough 2 to achieve uniform sorting of all blanks and spacers. After the sorting is completed, the first cylinder 52 drives the flattening plate 53 back to the initial position and waits for the next working cycle. Through this design, the finishing mechanism 5 can achieve efficient and accurate finishing of the NdFeB blank and the spacer, providing a good foundation for the subsequent magnetization process. At the same time, since the first cylinder 52 is used as the power source, the finishing mechanism 5 has a high degree of automation and reliability, which can reduce manual intervention and improve production efficiency.

[0025] Combination Figure 1 , Figure 3 , Figure 5 and Figure 6As shown, the finishing mechanism 5 also includes a second cylinder 54 relatively arranged on both sides of the conveying trough 2, and the output end of the second cylinder 54 is fixedly connected with a fixed clamping plate 55. Specifically, the design of the finishing mechanism 5 further reflects its efficiency and accuracy. In addition to the first cylinder 52 and the flattening plate 53 mentioned above, the newly added second cylinder 54 and the fixed clamping plate 55 provide additional stability and accuracy for the finishing process. The second cylinder 54 is relatively arranged on both sides of the conveying trough 2, which means that there are second cylinders 54 on both sides of the blank and the spacer to provide power. This design helps to ensure symmetry and balance during the finishing process, and avoid poor finishing effect or material damage due to uneven unilateral force. The fixed clamping plate 55 is fixedly connected to the output end of the second cylinder 54, and when the second cylinder 54 is extended and retracted, the fixed clamping plate 55 will move accordingly. The function of the fixed clamping plate 55 is to clamp and position the NdFeB blank and the spacer from both sides during the finishing process to prevent them from being displaced or tilted during the finishing process. During the sorting process, the first cylinder 52 drives the leveling plate 53 to move downward to perform preliminary compaction and sorting of the blanks and spacers. At the same time, the second cylinder 54 drives the fixed clamping plate 55 to clamp the materials from both sides to ensure that they remain in the correct position and spacing. This dual action not only improves the accuracy of sorting, but also helps prevent the material from moving or deforming in subsequent processes. Through this design, the sorting mechanism 5 can more accurately control the position and spacing of the NdFeB blanks and spacers, providing a more stable and reliable foundation for the subsequent magnetization process. At the same time, since the second cylinder 54 is used as the power source, the operation of the sorting mechanism 5 is more automated and efficient, which helps to improve the overall production efficiency.

[0026] Combination Figure 1 , Figure 2 , Figure 3 and Figure 4As shown, the blank feeding mechanism 3 includes a first vibration disk 31 installed on the workbench 1, and the output end of the first vibration disk 31 is connected to a first guide rail 32, which is vertical and fixedly connected to the conveying trough 2. Specifically, the design of the blank feeding mechanism 3 plays a vital role in the automation and efficient operation of the entire pre-magnetization device. The blank feeding mechanism 3 includes a first vibration disk 31 and a first guide rail 32, and these two components work together to realize the automatic feeding and accurate positioning of the NdFeB blank. The first vibration disk 31 is a commonly used automatic feeding device, which arranges the materials in order and conveys them to the designated position through vibration. Here, the first vibration disk 31 is installed on the workbench 1, which is responsible for sorting and conveying the NdFeB blanks. There are special tracks and vibration mechanisms inside the first vibration disk 31, which can be adjusted according to the shape and size of the blank to ensure that the blank can smoothly enter the next process. The first guide rail 32 is vertical and fixedly connected to the conveying trough 2, and its main function is to accurately guide the blank output from the first vibration disk 31 to the conveying trough 2. The design of the first guide rail 32 should ensure that the blank can slide smoothly and prevent it from tilting or falling during the transmission process. By accurately controlling the angle and length of the first guide rail 32, it can be ensured that the blank can accurately reach the predetermined position, laying the foundation for the smooth progress of the subsequent process. In the actual operation process, the first vibration plate 31 will vibrate continuously, arranging the NdFeB blanks in an orderly manner and conveying them to the entrance of the first guide rail 32. Then, the blank slides along the first guide rail 32 onto the conveying trough 2, and the conveying trough 2 conveys it to the next process. The entire loading process does not require manual intervention, which greatly improves production efficiency and automation. In addition, this design also has high flexibility. Since the first vibration plate 31 and the first guide rail 32 can be adjusted according to the shape and size of the blank, the loading mechanism can adapt to NdFeB blanks of different specifications, improving the versatility of the equipment. In general, the blank feeding mechanism 3 realizes automatic feeding and accurate positioning of the NdFeB blanks through the synergistic effect of the first vibration plate 31 and the first guide rail 32, providing a strong guarantee for the automation and efficient operation of the entire pre-magnetization device.

[0027] Combination Figure 1 , Figure 2 , Figure 3 and Figure 4As shown, the spacer feeding mechanism 4 includes a second vibration disk 41 installed on the workbench 1, and the output end of the second vibration disk 41 is connected to a second guide rail 42, and the second guide rail 42 is arranged in parallel with the first guide rail 32 and is fixedly connected to the conveying trough 2. Specifically, the design of the spacer feeding mechanism 4 plays a key role in the pre-magnetization device, ensuring that the spacers can be accurately and efficiently placed between adjacent NdFeB blanks. The spacer feeding mechanism 4 mainly includes a second vibration disk 41 and a second guide rail 42. The coordinated work of these two components enables the spacer feeding process to be automated and precisely controlled. The second vibration disk 41 is similar to the first vibration disk 31 in the blank feeding mechanism 3, and the second vibration disk 41 is responsible for sorting and conveying the spacers. Spacers are usually used to form intervals between NdFeB blanks to prevent adhesion or mutual interference during the subsequent magnetization process. The internal structural design of the second vibration disk 41 can adapt to the shape and size of the spacers, ensuring that the spacers can be output in an orderly manner. The second guide rail 42 is arranged in parallel with the first guide rail 32 and is also fixedly connected to the conveying trough 2. This parallel arrangement ensures that the spacer and the blank can be conveyed to the conveying trough 2 in the same direction, which is convenient for subsequent sorting and positioning. The design of the second guide rail 42 should take into account the size and weight of the spacer to ensure that it can slide smoothly to the predetermined position. During the actual operation, the second vibration plate 41 will vibrate continuously, arranging the spacers in an orderly manner and conveying them to the entrance of the second guide rail 42. Then, the spacer slides along the second guide rail 42 and is accurately placed between adjacent NdFeB blanks. Due to the fixed connection between the second guide rail 42 and the conveying trough 2, the spacer can accurately reach the predetermined position, which provides a guarantee for the smooth progress of subsequent processes. In addition, the automated design of the spacer feeding mechanism 4 reduces the need for manual intervention and improves production efficiency. At the same time, due to the precise control of the second vibration plate 41 and the second guide rail 42, the feeding process of the spacer is more accurate and reliable, reducing the error caused by human factors. In general, the spacer feeding mechanism 4 realizes automatic feeding and precise positioning of the spacers through the coordinated action of the second vibrating plate 41 and the second guide rail 42, providing strong support for the automation and efficient operation of the entire pre-magnetization device.

[0028] Combination Figure 1 , Figure 2 , Figure 3 and Figure 4As shown, an electric push rod 6 is provided at one end of the conveying trough 2, and the output direction of the output end of the electric push rod 6 is consistent with the conveying direction of the conveying trough 2. Specifically, in the pre-magnetization device, the setting of the electric push rod 6 is an important link, which enhances the functionality and automation of the entire device. The electric push rod 6 is installed at one end of the conveying trough 2, and the output direction of its output end is consistent with the conveying direction of the conveying trough 2. The electric push rod 6 is a device that converts electrical energy into mechanical energy, and the push rod is driven by the internal motor to perform telescopic movement. Here, the main function of the electric push rod 6 is to push or pull the NdFeB blank and the spacer assembly at the end of the conveying trough 2 so that it can smoothly enter the next process or equipment. When the NdFeB blank and the spacer are sorted by the sorting mechanism 5, a neat assembly is formed and moves forward along the conveying trough 2. When this assembly reaches the end of the conveying trough 2, the electric push rod 6 starts to work. The push rod extends, and its output end contacts the rear end of the assembly and applies a thrust. This thrust enables the assembly to overcome possible friction and resistance, smoothly leave the conveying trough 2 and enter the next process. The use of the electric push rod 6 not only improves production efficiency and reduces the need for manual intervention, but also ensures that the NdFeB blank and the spacer assembly can accurately and smoothly transition to the next process. This helps to reduce production delays and quality problems caused by improper operation or equipment failure. In addition, the electric push rod 6 can also be precisely controlled as needed. By adjusting the telescopic speed and strength of the electric push rod 6, effective pushing of NdFeB blanks and spacer assemblies of different specifications and weights can be achieved. This flexibility enables the pre-magnetization device to adapt to different production needs and improves the versatility and reliability of the equipment. In summary, the electric push rod 6 plays a role of promotion and transition in the pre-magnetization device, improves production efficiency and quality, reduces labor costs, and is an important part of the automation and efficient operation of the pre-magnetization device.

[0029] Combination Figure 1 , Figure 3 , Figure 5 and Figure 6As shown, the conveying trough 2 also includes a marking mechanism 7 for marking the sorted NdFeB blanks. Specifically, adding a marking mechanism 7 to the conveying trough 2 of the pre-magnetizing device is an innovative design, which can not only improve the traceability of the production process, but also help to improve product quality and production efficiency. The main function of the marking mechanism 7 is to mark the sorted NdFeB blanks. These marks can include information such as production batch, date, serial number, etc., which helps to track and manage products during the production process. Through marking, the company can accurately understand the production situation of each blank, including its raw material source, processing time, process parameters, etc., which is crucial for subsequent quality control and traceability. The marking mechanism 7 can be designed in various forms to meet different production needs. For example, it can use an inkjet printer or a laser marking machine to print information directly on the surface of the blank. These devices have the advantages of high precision, high speed, low consumables, etc., and can meet the needs of large-scale and high-efficiency production. In addition, the marking mechanism 7 can also be integrated with the control system of the pre-magnetizing device to achieve automatic marking. Through programming and sensors, the control system can automatically identify the location and quantity of the blanks, and control the marking mechanism 7 to mark at the correct time and location. This automated marking method not only improves production efficiency, but also reduces human errors and interventions. The application of the marking mechanism 7 can also bring other potential benefits to enterprises. For example, through marking information, enterprises can more easily analyze problems and bottlenecks in the production process, thereby optimizing production processes and improving production efficiency. In addition, for blanks that require customization or special processing, marking information can also help workers quickly identify and process them, thereby improving production flexibility. In summary, the marking mechanism 7 is a very practical functional component in the pre-magnetization device, which can not only improve product traceability, but also help improve production efficiency and product quality. With the development of industrial automation and informatization, marking mechanisms will be widely used in more fields.

[0030] Combination Figure 1 , Figure 3 , Figure 5 and Figure 6As shown, the marking mechanism 7 includes a fixed frame 71 installed above the conveying trough 2, a servo motor 72 is installed on the fixed frame 71, and a marking machine 73 is fixedly connected to the output end of the servo motor 72. Specifically, the detailed design of the marking mechanism 7 reflects a high degree of automation and precision, which are essential for ensuring the accurate marking of the NdFeB blanks and improving production efficiency. First, the fixed frame 71 is installed above the conveying trough 2 as the basis of the entire marking mechanism 7. Its main function is to stably support the servo motor 72 and the marking machine 73 to ensure that they do not shake or move during operation. The fixed frame 71 is usually made of strong and durable materials to withstand the load and vibration during operation. The servo motor 72 is the core component of the marking mechanism 7 and is installed on the fixed frame 71. It is a motor that can accurately control position and speed, and has the characteristics of fast response and high-precision positioning. By accurately adjusting the servo motor 72 through the control system, the precise movement of the marking machine 73 in three-dimensional space can be achieved, thereby ensuring that each NdFeB blank can be accurately marked. The marking machine 73 is a component that actually performs the marking task and is fixedly connected to the output end of the servo motor 72. When the servo motor 72 receives the command from the control system, it drives the marking machine 73 to move according to the preset path and speed, and marks the NdFeB blank at the specified position. The marking machine 73 can adopt a variety of technologies, such as laser marking, inkjet marking, etc., and selects a suitable marking method according to specific needs and scenarios. The workflow of the entire marking mechanism 7 is as follows: when the NdFeB blank is transported to the specified position, the control system sends an instruction to the servo motor 72, and the servo motor 72 drives the marking machine 73 to move to the corresponding position. Then, the marking machine 73 marks the blank according to the preset marking content and format. After the marking is completed, the servo motor 72 and the marking machine 73 will return to the initial position and wait for the next marking task. This design not only improves the accuracy and efficiency of the marking, but also reduces the need for manual intervention, making the entire pre-magnetization device more automated. At the same time, by accurately controlling the movement of the servo motor 72 and the marking parameters of the marking machine 73, it is also possible to achieve flexible and accurate marking of NdFeB blanks of different specifications and materials. In summary, the marking mechanism 7 achieves automatic and accurate marking of NdFeB blanks through the coordinated work of the fixing frame 71, the servo motor 72 and the marking machine 73, thereby improving production efficiency and product quality.
