Description

Technical Field

[0001] This utility model relates to the field of neodymium iron boron magnet processing feeding technology, specifically a neodymium iron boron magnet grinding processing feeding mechanism. Background Technology

[0002] Neodymium iron boron (NdFeB) materials are widely used in the field of magnetic materials. However, NdFeB magnets require high planar quality to ensure the stability and uniformity of the magnetic field they form. Therefore, NdFeB magnets require surface grinding during the manufacturing process.

[0003] In the grinding process of neodymium iron boron magnets, the efficiency, precision and stability of the feeding process directly affect the overall production rhythm and product quality. The neodymium iron boron magnet sheets to be processed must be accurately and orderly transported to the grinding station.

[0004] Currently, the feeding of neodymium iron boron magnets in the market mostly relies on manual operation. Manual feeding requires operators to place the magnetic sheets one by one onto the conveyor table or grinding station. This method is not only labor-intensive and frequent, but also has a limited feeding speed, making it difficult to match the continuous processing rhythm of the grinding equipment. Often, the grinding station is left idle due to untimely manual replenishment, which slows down the overall production efficiency. At the same time, manual placement of magnetic sheets is easily affected by operating techniques and visual judgment errors, which can cause the magnetic sheets to shift on the conveyor table or station. This can lead to insufficient processing dimensional accuracy, increased scrap rate, and in severe cases, even damage to the grinding equipment due to magnetic sheet misalignment and collision.

[0005] Neodymium iron boron (NdFeB) magnetic sheets are a widely used structure for NdFeB magnets, particularly in mass production.

[0006] Therefore, we proposed a feeding mechanism for grinding neodymium iron boron magnets to solve the problems mentioned above. Utility Model Content

[0007] The purpose of this invention is to provide a feeding mechanism for grinding neodymium iron boron magnets, in order to solve the problems mentioned in the background art. The existing feeding mechanisms have limited feeding speed, which is difficult to match the continuous processing rhythm of the grinding equipment. The grinding station is often idle due to untimely manual replenishment, which slows down the overall production efficiency. Furthermore, it is easy to cause the magnetic sheet to shift on the conveyor table or station, which leads to insufficient processing dimensional accuracy and increased scrap rate. In severe cases, the magnetic sheet may even collide with the grinding equipment, causing equipment damage.

[0008] This utility model provides the following technical solution: a feeding mechanism for grinding neodymium iron boron magnets, including a belt conveyor table one, a feeding assembly installed on the belt conveyor table one, the feeding assembly including base piles on both sides of the belt conveyor table, a feeding seat fixed on the base piles, a storage box installed on the feeding seat, a plurality of neodymium iron boron magnet sheets placed in the storage box, a belt conveyor table two installed on the end side of the belt conveyor table one, and a flipping assembly provided between the belt conveyor table one and the belt conveyor table two.

[0009] Preferably, the feeding seat has a cavity, a feeding port on the top surface, and a discharge port on the bottom surface, with a guide plate connected to the bottom surface of the discharge port.

[0010] Preferably, a feeding frame is slidably connected inside the cavity. The feeding frame is hollow, with its top surface matching the feeding port and its bottom surface matching the discharge port.

[0011] Preferably, electric push rods are symmetrically fixed on both sides of the feeding seat, a connecting block is fixed to the output end of the electric push rod, a connecting rod is fixed to the side wall of the connecting block, the connecting rod is fixedly connected to the feeding frame, and arc-shaped grooves are opened on both sides of the feeding seat, and the connecting rod is slidably connected to the arc-shaped grooves.

[0012] Preferably, the flipping assembly includes a base, two bases are symmetrically arranged, one of the bases has a fixing plate fixed to its side wall, a motor is fixed to the fixing plate, a rotating rod is fixed to the output end of the motor, a sleeve is fixedly sleeved on the outer ring of the rotating rod, and a material distribution plate is fixedly sleeved on both sides of the sleeve, and multiple feeding slots are opened in the material distribution plate.

[0013] Preferably, multiple feed troughs are arranged in a circumferential array, and one side of the feed trough is aligned with the conveying surfaces of belt conveyor platform one and belt conveyor platform two.

[0014] This utility model has the following beneficial effects: 1. This mechanism can improve the feeding efficiency of NdFeB magnetic sheets, eliminating the need for manual placement of NdFeB magnetic sheets one by one. Through batch storage and automatic continuous feeding, it reduces the frequency of manual operation, avoids station idling due to untimely manual replenishment, and allows the feeding rhythm to be precisely matched with the grinding cycle, effectively improving the overall production efficiency.

[0015] 2. This mechanism can improve the positioning accuracy of the feeding. From the moment the NdFeB magnetic sheet falls into the feeding frame to the moment it slides into the belt conveyor table, the multi-structure adaptation design avoids the NdFeB magnetic sheet from shifting position, reducing the problems of insufficient processing dimensional accuracy and increased scrap rate caused by positioning deviation. At the same time, it reduces the risk of damage to the grinding equipment caused by the NdFeB magnetic sheet shifting.

[0016] 3. This mechanism ensures the stability and seamlessness of the feeding process, effectively preventing NdFeB magnetic sheets from falling out of the storage box prematurely, avoiding accumulation and jamming of NdFeB magnetic sheets in the cavity, eliminating the need for manual cleaning, ensuring orderly connection between material receiving and unloading processes, reducing extra workload, improving the overall stability of the feeding process, and achieving dynamic balance between feeding and processing. It flexibly adjusts the feeding rhythm according to the actual grinding processing time, preventing idle workstations due to slow feeding and magnetic sheet accumulation due to excessive feeding, allowing for efficient connection between processing and feeding processes, and further optimizing the production process.

[0017] 4. This mechanism can solve the problem of flipping efficiency during double-sided grinding of NdFeB magnetic sheets. It eliminates the need for manual removal, flipping, and repositioning of magnetic sheets, enabling simultaneous transfer and flipping of magnetic sheets from conveyor belt one to conveyor belt two. It can also continuously complete the flipping of multiple magnetic sheets, eliminating process interruptions caused by manual flipping, significantly improving double-sided processing efficiency, and reducing labor costs.

[0018] 5. This mechanism can reduce the risk of damage during the flipping process of NdFeB magnetic sheets. The NdFeB magnetic sheets are flipped without contact and with multiple protective designs to avoid edge breakage and surface scratches caused by improper manual handling or magnetic sheets falling. It also reduces damage caused by collisions between magnetic sheets and conveyor surfaces and workstations, effectively reducing the scrap rate and ensuring the quality of magnetic sheet processing.

[0019] 6. This mechanism can guarantee the positioning accuracy of NdFeB magnetic sheets after flipping, ensuring that the NdFeB magnetic sheets maintain a precise position before and after flipping, ensuring a unified reference for double-sided grinding, avoiding problems such as asymmetrical processing dimensions and substandard accuracy caused by flipping positioning deviations, and further improving the processing accuracy of double-sided grinding of NdFeB magnetic sheets.

[0028] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0029] Example 1: This embodiment aims to address the problems of low efficiency and easy positioning deviations in manual loading during the processing of NdFeB magnets. Please refer to [link to relevant documentation]. Figure 1 - Figure 7 The feeding mechanism for grinding neodymium iron boron magnets includes a belt conveyor table 1, a feeding assembly 3 installed on the belt conveyor table 1, the feeding assembly 3 includes base piles 31 on both sides of the belt conveyor table, a feeding seat 32 fixed on the base piles 31, a storage box 33 installed on the feeding seat 32, and multiple neodymium iron boron magnet sheets 4 placed in the storage box 33.

[0030] The feeding seat 32 has a cavity 34, a feeding port 35 on the top surface of the feeding seat 32, and a discharge port 36 on the bottom surface of the feeding seat 32. The bottom surface of the discharge port 36 is connected to a guide plate 37. A feeding frame 38 is slidably connected in the cavity 34. The feeding frame 38 is hollow. The top surface of the feeding frame 38 is adapted to the feeding port 35, and the bottom surface of the feeding frame 38 is adapted to the discharge port 36. The feeding port 35 on the top surface of the feeding seat 32 is precisely aligned with the bottom opening of the storage box 33, and the size of the feeding port 35 is slightly larger than the size of a single neodymium iron boron magnetic sheet 4, ensuring that the magnetic sheet can fall smoothly into the cavity 34, while avoiding multiple magnetic sheets from getting stuck in the feeding port 35 at the same time. The discharge port 36 on the bottom surface is connected to the top of the guide plate 37 below. The size of the discharge port 36 is perfectly matched with the bottom size of the feeding frame 38, ensuring that the magnetic sheets in the feeding frame 38 can fall completely into the guide plate 37 without any residue or risk of falling off.

[0031] Electric push rods 39 are symmetrically fixed on both sides of the feeding seat 32. A connecting block 310 is fixed at the output end of the electric push rod 39. A connecting rod 311 is fixed on the side wall of the connecting block 310. The connecting rod 311 is fixedly connected to the feeding frame 38. Arc grooves 312 are opened on both sides of the feeding seat 32. The connecting rod 311 is slidably connected to the arc groove 312.

[0032] In this embodiment: In the grinding process of neodymium iron boron magnetic sheet 4, the magnetic sheet needs to be transported to the grinding station for processing via belt conveyor table 1. There are two grinding processes in this solution, corresponding to belt conveyor table 1 and belt conveyor table 2 respectively. However, since the core innovation of this technical solution focuses on the feeding structure, the grinding process is only mentioned as necessary and will not be described in detail. The specific feeding operation process is as follows: First, place the multiple neodymium iron boron magnetic sheets 4 to be processed into the storage box 33 in a regular posture. The bottom of the storage box 33 is precisely aligned with the feeding port 35 of the feeding seat 32. The neodymium iron boron magnetic sheets 4 can fall naturally by their own gravity or fall into the cavity 34 inside the feeding seat 32 with a slight auxiliary push, and finally enter the hollow feeding frame 38. When it is necessary to feed magnetic sheets to the subsequent grinding process, start the electric push rods 39 symmetrically installed on both sides of the feeding seat 32. The output end of the electric push rod 39 will drive the connecting block 310 fixed thereto to move in a straight line. The connecting block 310 further pulls the connected connecting rod 311 to move synchronously. Since the connecting rod 311 and the arc groove 312 opened on both sides of the feeding seat 32 form a sliding fit, during the process of the connecting rod 311 moving along the trajectory of the arc groove 312, it will drive the feeding frame 38 to achieve precise position adjustment in the cavity 34. In the initial state, the top surface of the feeding frame 38 is completely aligned with the feeding port 35 to ensure that the neodymium iron boron magnetic sheet 4 can fall stably into the frame. After the neodymium iron boron magnetic sheet 4 smoothly enters the feeding frame 38, the electric push rod 39 drives the feeding frame 38 to move, so that its bottom surface gradually aligns with the discharge port 36 of the feeding seat 32. At this time, the neodymium iron boron magnetic sheet 4 in the feeding frame 38 will fall into the guide plate 37 connected below through the discharge port 36.

[0033] It should be noted that the specifications of the feeding frame 38 and the feeding base 32 can be customized according to actual processing requirements. During the feeding process, the side wall of the feeding frame 38 will effectively resist the neodymium iron boron magnetic sheets 4 to be fed in the storage box 33. This design can prevent the magnetic sheets in the storage box 33 from falling off in advance during the feeding process, thereby ensuring the orderly connection of the neodymium iron boron magnetic sheet 4 receiving and unloading process and greatly improving the stability of the receiving and unloading process. Subsequently, the neodymium iron boron magnetic sheet 4 is smoothly guided by the guide plate 37 onto the conveyor surface of the belt conveyor table 1. Finally, the belt conveyor table 1 transports the magnetic sheet to the next processing step at a uniform speed and with a stable posture, completing a single automatic feeding process. The entire feeding process requires no manual intervention. The feeding rhythm can be flexibly adjusted by controlling the start and stop frequency of the electric push rod 39. At the same time, the structural compatibility design of the feeding frame 38 with the feeding port 35 and the discharge port 36 can effectively prevent deviation during the conveying of the magnetic sheet, further improving the stability and efficiency of the feeding. In addition, the feeding process can be precisely coordinated and controlled according to the actual time consumption of grinding. By matching the grinding cycle, it ensures that after the previous magnetic sheet is ground, the subsequent magnetic sheets to be processed can be promptly conveyed to fill the gap. This avoids the impact of station idling on efficiency and prevents magnetic sheets from accumulating on the conveyor table or grinding station due to excessive feeding, thus achieving efficient connection and dynamic balance between processing and feeding.

[0034] Example 2: This embodiment aims to address the problems of time-consuming manual flipping operations, easy damage to the magnetic sheet, and poor positioning accuracy during double-sided grinding of NdFeB magnetic sheets. This embodiment is an improvement upon Embodiment 1. For details, please refer to [link to Embodiment 1]. Figure 1 - Figure 3 Belt conveyor 1 is equipped with belt conveyor 2 on its end side. Belt conveyor 1 serves as the initial conveying carrier. Its main function is to receive the neodymium iron boron magnetic sheets 4 to be processed from the feeding component 3 and to smoothly transport the neodymium iron boron magnetic sheets 4 to the flipping component 5 or the corresponding grinding station. The belts of belt conveyor 1 and belt conveyor 2 are made of wear-resistant and non-slip material to ensure that the magnetic sheets are not easy to slip or deviate during the conveying process. The belt running speed can be adjusted according to the grinding process rhythm to achieve precise matching with the feeding frequency of the feeding component 3.

[0035] A flipping assembly 5 is provided between belt conveyor 1 and belt conveyor 2. The flipping assembly 5 includes a base 51, and two bases 51 are symmetrically arranged. A fixing plate 52 is fixed to the side wall of one of the bases 51. A motor 53 is fixed on the fixing plate 52. A rotating rod 54 is fixed to the output end of the motor 53. A sleeve 55 is fixedly sleeved on the outer ring of the rotating rod 54. A material distribution plate 56 is fixedly sleeved on both sides of the sleeve 55. Multiple feeding slots 57 are opened in the material distribution plate 56.

[0036] Multiple feed troughs 57 are arranged in a circumferential array, with one side of each feed trough 57 aligned with the conveying surfaces of belt conveyor 1 and belt conveyor 2. The depth and width of each feed trough 57 are matched to the thickness and width of the neodymium iron boron magnetic sheet 4 to ensure that the magnetic sheet can be fully embedded in the trough, and the edges of the trough opening are rounded to avoid scratching the magnetic sheet.

[0037] In this embodiment: after the NdFeB magnetic sheet 4 is processed at the grinding station corresponding to the belt conveyor table 1, it will move to its end with the conveying action of the belt conveyor table 1, and then gradually enter the feeding groove 57 of the material distribution plate 56 in the flipping assembly 5. Since the groove opening on one side of the feeding groove 57 is designed to be on the same straight plane as the conveying surface of the belt conveyor table 1, the NdFeB magnetic sheet 4 can slide smoothly into the feeding groove 57 along the conveying direction, effectively avoiding the problem of NdFeB magnetic sheet 4 getting stuck or colliding due to groove misalignment, and ensuring the stability of the posture of the NdFeB magnetic sheet 4 when entering the feeding groove 57.

[0038] At this time, the drive motor 53 on the fixed plate 52 in the flipping assembly 5 is started. The output end of the motor 53 will drive the rotating rod 54, which is fixed on the same axis, to rotate at a constant speed. The rotating rod 54 further drives the sleeve 55, which is fixedly sleeved on the outer ring, to rotate synchronously. The material distribution plate 56, which is symmetrically installed on both sides of the sleeve 55, will move in a circular motion with the sleeve 55. The multiple feeding slots 57, which are arranged in a circular array inside the material distribution plate 56, will receive the processed magnetic sheets conveyed from the end of the belt conveyor table 1 in sequence as the material distribution plate 56 rotates, so as to realize continuous material receiving operation. When the feed trough 57 containing the neodymium iron boron magnetic sheet 4 rotates to the 180-degree position with the distribution plate 56, the overall orientation of the feed trough 57 will be flipped, and the magnetic sheet processing surface that was originally facing upwards will turn downwards. At the same time, the other side of the feed trough 57 is exactly aligned with the conveying surface of the belt conveyor table 2. As the distribution plate 56 continues to rotate at a constant speed, the flipped neodymium iron boron magnetic sheet 4 will slide smoothly from the feed trough 57 onto the conveying surface of the belt conveyor table 2 under the combined action of its own gravity and the rotational inertia of the distribution plate 56. This completes the automatic flipping and cross-conveyor transfer of the magnetic sheet. Subsequently, the belt conveyor 2 will accurately transport the flipped NdFeB magnetic sheet 4 to its corresponding grinding station so that the unprocessed other side of the NdFeB magnetic sheet 4 can be ground. The entire flipping and transfer process is completely synchronized with the conveying rhythm of the NdFeB magnetic sheet 4 on the conveyor, without any additional stops or waiting. The multiple feed slots 57 distributed in a circular array on the distribution plate 56 can continuously and alternately receive, flip, and transport magnetic sheets, realizing continuous and uninterrupted flipping operations. This design not only eliminates the time cost of manual flipping and greatly improves processing efficiency, but also ensures the positional accuracy of the magnetic sheet before and after flipping through the straight alignment structure of the feed groove 57 and the conveying surface, effectively avoiding subsequent processing deviations caused by positional offset. At the same time, the uniform rotation of the distribution plate 56 and the matching design of the feed groove 57 make the flipping process of the neodymium iron boron magnetic sheet 4 short and with small shaking amplitude. While quickly completing the flipping operation, it minimizes the damage to the magnetic sheet caused by collision and vibration, further ensuring the processing quality of the magnetic sheet.
