[0036] In order to clearly understand the technical solution of the present application, a NdFeB edge grinding tool provided by the present application will be described in detail below with reference to specific embodiments and drawings.

[0037] The terms used in the following examples are only for the purpose of describing specific embodiments and are not intended to limit the present application. As used in the specification and claims of this application, the singular expressions "a," "an," "above," "the," and "this" are intended to include expressions such as "one or more," unless the context clearly indicates otherwise. It should also be understood that in the following examples of this application, "at least one," "one or more" refer to one, two, or more than two.

[0038] References to "one embodiment" or "some embodiments" in this specification mean that a particular feature, structure, or characteristic described in conjunction with that embodiment is included in one or more embodiments of the present application. Thus, phrases such as "one embodiment," "some embodiments," "in other embodiments," and "in other embodiments" appearing in various places in this specification do not necessarily refer to the same embodiment, but rather mean "one or more, but not all, embodiments," unless otherwise specifically emphasized. The terms "including," "comprising," "having," and variations thereof mean "including but not limited to," unless otherwise specifically emphasized.

[0039] Example 1: This example provides a NdFeB edge grinding tool, referring to Figure 2 , which shows a schematic diagram of the three-dimensional structure of the NdFeB edge grinding tool. As can be seen from the figure, the NdFeB edge grinding tool includes a vibration plate 1, which is used to hold NdFeB magnets. The vibration plate 1 is connected to the transport mechanism to transport the material (i.e., NdFeB magnets) to the transport mechanism. The transport mechanism is arranged on a transport bracket 2, and the transport bracket 2 is fixed to the base 5 to provide support and operation basis for the transport mechanism. The transfer chamber 3 is connected to the transport mechanism to receive the NdFeB magnets transported by the transport mechanism. The support frame 4 supports the transfer chamber 3 and is connected to the grinding mechanism at the same time, so that the grinding mechanism is in the corresponding working position to realize the grinding process of the NdFeB magnets.

[0040] Through the above-mentioned connection relationship, the various components of the present invention form a coordinated system on the base 5 to sequentially realize functions such as material transmission, transfer and polishing.

[0041] Specifically, further combined Figure 2 and Figure 3 The schematic diagram of the appearance structure of the vibration disk 1 is shown in the figure. It can be seen from the figure that the vibration disk 1 includes a disk body 7, which is connected to the material guide track 6. By combining with the vibration motor on the disk body 7, the neodymium iron boron magnet in the disk body 7 is transported to the material guide track 6. The material guide track 6 is arranged in a serpentine shape in the vibration disk 1, and its end is connected to the top outlet of the vibration disk 1 to guide the material to move along a specific path and be transported to the top outlet of the vibration disk 1. The baffle 8 is installed on the material guide track 6 to assist in controlling the movement of the neodymium iron boron magnet in the material guide track 6, ensuring that the neodymium iron boron magnet is output from the top outlet of the vibration disk 1 along a predetermined trajectory, so that the neodymium iron boron magnet can be smoothly delivered to the transportation mechanism.

[0042] Specifically, further combined Figure 2 and Figure 4 ,in, Figure 4The figure shows the installation structure of the transport mechanism and the transport bracket 2. As can be seen from the figure, the transport mechanism includes a steering gear 12. The transport bracket 2 serves as a basic support structure and provides an installation and bearing platform for other components. The steering gear 12 is fixedly installed at one end of the transport bracket 2 and serves as a power source to provide power for the operation of the conveyor belt 11. The power output end of the steering gear 12 is connected to one end of the closed loop conveyor belt 11 through a transmission connection. The other end of the conveyor belt 11 is wrapped around the roller 9. The feeding end of the conveyor belt 11 is opposite to the top outlet of the vibrating disk 1. The roller 9 is installed at the other end of the transport bracket 2 and is rotatably connected to the flange 10. The flange 10 is firmly fixed to the transport bracket 2 to ensure the stability and precision of the roller 9 during rotation. During operation, the steering gear 12 drives the conveyor belt 11 to move, and the conveyor belt 11 drives the roller 9 to rotate synchronously, realizing functions such as the transmission of neodymium iron boron magnets.

[0043] Specifically, further combined Figure 2 and Figure 5-6 ,in, Figure 5 The figure shows the assembly structure of the transfer chamber 3 and the transport mechanism. Figure 6 What is shown is a schematic diagram of a separate three-dimensional structure of the transfer chamber 3. As can be seen from the figure, a transfer chamber 3 is provided on one side of the discharge end of the conveyor belt 11, and the discharge end of the conveyor belt 11 is docked with the channel 14 of the transfer chamber 3. The conveyor belt 11 is responsible for transporting the NdFeB magnet to the entrance of the channel 14 of the transfer chamber 3 to realize the transfer of materials. The channel 14 is a special-shaped structure, which is specially adapted for NdFeB magnet products to ensure the adaptability and stability of material transmission. The transfer chamber 3 is mounted on the support frame 4, which provides a stable support for the transfer chamber 3 to ensure that it remains stable during operation. The two first grooves 13 are respectively arranged on the left and right sides of one end of the transfer chamber 3, and the grinding port 15 is arranged on the corresponding first groove 13, providing a working interface for the grinding mechanism, so that the grinding mechanism can accurately grind the material in the transfer chamber 3 through the grinding port 15. This layout design helps to optimize space utilization and operational convenience, ensuring the efficient conduct of the grinding work.

[0044] Specific, combined Figure 2 and Figure 7-8 ,in, Figure 7 The diagram shows the installation structure of the grinding mechanism. Figure 8The diagrams depict a three-dimensional structure of the grinding mechanism. As can be seen from the two figures above, the grinding mechanism includes a movable base 17, a guide slot 18 formed on a support frame 4, and two movable bases 17 slidably connected within the guide slot 18, allowing the movable bases 17 to move along the guide slot 18. The two movable bases 17 are each threadedly connected to a lead screw 19, with the threads on the lead screw 19 corresponding to the two movable bases 17 rotating in opposite directions. The lead screw 19 is rotatably connected to a base 20, which is embedded in the guide slot 18. When the lead screw 19 is rotated by a rotary motor 22, the two movable bases 17 move relative to or away from each other, achieving position adjustment. A first hinged base 23 is rotatably connected to a second hinged base 25. The first hinged base 23 is fixedly connected to the output shaft of a swing motor 24 on the movable base 17, and the first hinged base 23 is fixedly connected to the swing motor 24. When the swing motor 24 is in operation, the rotational connection between the two hinged bases drives the grinding motor 21 and the grinding wheel 16 to swing, achieving flexible adjustment of the grinding angle. The grinding motor 21 drives the grinding wheel 16 to rotate, and grinds the material at the grinding opening 15 on the transfer chamber 3.

[0045] The present invention's workflow is generally as follows: First, the vibration motor within the vibrating plate 1 moves the NdFeB magnets along the serpentine guide track 6, with the baffle 8 assisting in controlling their trajectory. The magnets are then output from the top outlet of the vibrating plate 1 to the conveyor belt 11. Then, the servo 12 drives the conveyor belt 11, rotating the roller 9 and feeding the NdFeB magnets from the discharge end of the conveyor belt 11 through the shaped channel 14 (compatible with the NdFeB magnets) in the transfer chamber 3, which is securely supported by the support frame 4. Finally, the lead screw 19 rotates, driving the two movable seats 17 to move relative to or away from each other within the chute 18 to adjust their position. The swing motor 24, rotatably connected via the first and second hinged seats 23 and 25, drives the grinding motor 21 and grinding wheel 16 to swing, adjusting the grinding angle. The grinding motor 21 drives the grinding wheel 16 to rotate, precisely grinding the NdFeB magnets through the grinding opening 15 in the first groove 13 of the transfer chamber 3.

[0046] The present invention drives the two movable seats 17 to move along the slide groove 18 through the screw 19, and the swing motor 24 adjusts the angle between the grinding motor 21 and the grinding wheel 16 through the hinge seat. The grinding wheel 16 grinds the neodymium iron boron magnet in the transfer cavity 3 through the grinding port 15. The base 20 ensures the stability of the system, forming a flexible and precise grinding system. Compared with the existing technology, the problem of how to adjust the angle of the grinding wheel 16 is solved.

[0047] In order to ensure that the NdFeB magnet can move smoothly in the transfer chamber 3 and facilitate the grinding operation of the NdFeB magnet by the grinding wheel 16, the present invention is optimized as follows: Figure 9, a schematic diagram of the installation structure of the auxiliary mechanism is shown. As can be seen from the figure, the auxiliary mechanism includes a support arm 30, which is fixedly connected to the base 5 to provide a support base for other components. The auxiliary motor 26 is installed on the support arm 30, and its output shaft is connected to one end of the belt to provide power for the transmission. The other end of the belt is connected to the push wheel 29, and the push wheel 29 is driven by the belt. A second groove 27 is provided on the transfer chamber 3, and a through hole 28 is located at the second groove 27 (as shown in FIG. Figure 6 A push wheel 29 is positioned on one side of the corresponding second groove 27 and is rotationally connected to the support frame 4. The push wheel 29 is configured to contact and mate with the NdFeB magnet. During operation, the auxiliary motor 26 rotates, driving the push wheel 29 via a belt. This push wheel 29 propels the NdFeB magnet within the transfer chamber 3, passing through the subsequent grinding opening 15 for engagement with the grinding wheel 16 for grinding.

[0048] As an optimization solution of this embodiment, refer to Figure 10 , showing a schematic diagram of the installation structure of the first guide plate 31 and the second guide plate 32. As can be seen from the figure, the NdFeB edging tooling also includes the first guide plate 31 and the second guide plate 32. The first guide plate 31 is connected to the baffle 8; the second guide plate 32 is connected to the plate 7, organically integrating the plate 7 with the transport mechanism. Both the first guide plate 31 and the second guide plate 32 are positioned above the conveyor belt 11, guiding and regulating the movement of the NdFeB magnets above the conveyor belt 11, preventing them from shifting or shaking during transport, significantly improving the stability and reliability of the conveyor process.

[0049] Example 2: When processing NdFeB magnets, in addition to grinding the edges of the top of the NdFeB magnets, it is also necessary to polish both sides of the top and the left and right sides of the NdFeB magnets. For this purpose, the NdFeB edge grinding tool also includes a polishing mechanism, such as Figure 11 The figure shows a schematic diagram of the assembly structure of the polishing mechanism. As can be seen from the figure, the polishing mechanism is connected to the upper portion of the transport mechanism and is used to polish the top and left and right sides of the NdFeB magnet. The specific structure of the polishing mechanism is as follows.

[0050] Combine Figure 11-12 ,in, Figure 12The three-dimensional structure of the polishing mechanism is shown in the figures. As can be seen from the two figures above, the polishing mechanism includes a hanger 33. The bottom of the hanger 33 is fixed to the first guide plate 31 (or the second guide plate 32), and the top of the hanger 33 is fixed to the support plate 34. The hanger 33 serves as a bridge connecting the support plate 34 with the first guide plate 31 or the second guide plate 32, providing a suspension or support base for the entire polishing mechanism. The support plate 34 serves as the main mounting platform, and a limit rod 44 is connected to the support plate 34. The magnet 39 is slidably connected to the support plate 34, allowing the magnet 39 to move on the surface of the support plate 34. The magnet 39 is slidably mounted on the limit rod 44, allowing it to slide along the limit rod 44. The ends of the second spring 36 are respectively fixed to the magnet 39 and the limit rod 44, providing an elastic restoring force for the magnet 39. The first electromagnet 41 is mounted on the support plate 34, providing magnetic control for the magnet 39 and influencing its movement through magnetic force. A limit frame 37 is fixed beneath the support plate 34. A push block 38 is slidably connected to the limit frame 37, allowing the push block 38 to slide vertically within the limit frame 37. A first spring 35 is positioned near the limit frame 37, with its ends fixedly connected to the limit frame 37 and the push block 38, respectively, providing an elastic return force for the push block 38. A scraper 43 is fixed to the magnet 39, and a wedge 40 is fixed to the push block 38. The upward and downward movement of the push block 38 drives the wedge 40, which then engages with the socket 42 on the scraper 43. A second electromagnet (not shown) is located at the bottom of the push block 38.

[0051] In combination with the above-mentioned connection relationship, the working principle of the polishing mechanism is as follows: when the NdFeB magnet moves to the bottom of the push block 38 and the second electromagnet is energized, due to the adsorption of the second electromagnet, the NdFeB magnet contacts the bottom of the limit frame 37 and forces the bottom of the push block 38 to be flush with the bottom of the limit frame 37. After the wedge block 40 moves upward, it disengages from the socket 42. The second spring 36 pulls the magnet 39 and the scraper 43 to slide backward. The two scrapers 43 polish the top two sides and the left and right sides of the NdFeB magnet while moving. When the second electromagnet is powered off, the NdFeB magnet loses contact with the bottom of the limit frame 37, and the polished NdFeB magnet falls back onto the conveyor belt 11. The push block 38 moves downward and returns to its original position under the pull of the first spring 35. At this time, the first electromagnet 41 is energized, and the first electromagnet 41 attracts the magnet 39 to move forward and return to its original position. The second spring 36 is stretched and deformed, and the scraper 43 slides over the slope of the wedge block 40 to re-connect the wedge block 40 with the socket 42 of the scraper 43 (the scraper 43 needs to rely on the elastic force of the first spring 35 when sliding over the wedge block 40).

[0052] The present invention has the following beneficial effects by setting up a polishing mechanism: through the coordinated control of the second electromagnet, the first electromagnet 41 and the spring, the automatic polishing of the top two sides and the left and right sides of the NdFeB magnet is achieved, reducing manual intervention and greatly improving the efficiency of the polishing operation. The magnetic adsorption and release of the electromagnet are used to accurately control the movement of the magnet 39, the scraper 43 and the push block 38. Combined with the elastic reset force of the spring, the polishing action is ensured to be stable and repeatable, and the consistency of the polishing quality is guaranteed. The two scrapers 43 can polish the top two sides and the left and right sides of the NdFeB magnet at the same time during the movement process, completing the processing of multiple parts in one operation, and improving the polishing efficiency and uniformity. The plug-in adaptation of the wedge block 40 and the scraper 43 socket 42, as well as the sliding design of the magnet 39 along the limit rod 44 and the bearing plate 34, make the mechanism move smoothly and coordinated during the polishing and reset process, and use the spring elastic force to achieve automatic adaptation of the scraper 43 and the wedge block 40, optimizing the workflow. The hanger 33 connects the bearing plate 34 with the guide plate, integrating the polishing mechanism into the transport mechanism, resulting in a compact structure and high space utilization, which facilitates the layout and operation of the entire equipment.

[0053] Example 3: When polishing the top and left and right sides of the NdFeB magnet, a large amount of debris will be generated. At this time, the debris on the surface of the NdFeB magnet needs to be blown away in time. For this purpose, the NdFeB edge grinding tool also includes a dust removal mechanism, such as Figure 13-14 As shown, Figure 13 The diagram shows the assembly structure of the chip removal mechanism. Figure 14 The diagram below shows a schematic diagram of the chip removal mechanism. It is connected to the polishing mechanism and is used to remove debris from the surface of the NdFeB magnet. The chip removal mechanism consists of a transmission unit, a swing unit, and a reciprocating unit. The detailed structure of the chip removal mechanism is as follows.

[0054] refer to Figure 14-15 ,in, Figure 15 The three-dimensional structural diagram of the transmission unit is shown. As can be seen from the figure, the transmission unit includes a chain belt 45, which is wrapped around the first support shaft 46 and the second support shaft 47 to form a transmission structure. The first support shaft 46 and the second support shaft 47 are fixedly connected to the bearing plate 34, serving as support components for the chain belt 45, so that the chain belt 45 can run stably between the two shafts to achieve the transmission function. The chain belt 45 and the first support shaft 46 and the second support shaft 47 are wrapped around to form a transmission connection relationship, ensuring that the chain belt 45 maintains a stable transmission path during operation. The side end of the chain belt 45 is fixed to the magnet 39 on the adjacent side by a connecting rod 48. A swing unit is connected to the transmission unit, and the specific structure of the swing unit is as follows.

[0055] refer to Figure 14 、 16 ,in, Figure 16 The diagram shows a three-dimensional structural diagram of the swing unit. As can be seen from the figure, the swing unit includes a suspension frame 55, which is fixedly connected to the support plate 34 and serves as the supporting base for the linkage unit, providing mounting support for other components. A transmission gear 52 is rotatably connected to the suspension frame 55 and meshes with the chain belt 45, deriving power from the chain belt 45. A pin 53 fixed to the suspension frame 55 is rotatably connected to the swing arm 49. The pin 53 is fixedly connected to the center of the sector gear 54, allowing the sector gear 54 and the swing arm 49 to swing about the pin 53. An eccentric shaft 50 is mounted on the transmission gear 52, which slidably engages a guide slot 51 on the swing arm 49. The swing of the swing arm 49 is constrained by the guide slot 51 and the eccentric shaft 50, ensuring that the swing arm 49 moves along a specific trajectory. A reciprocating motion unit is also rotatably connected to the swing unit. The specific structure of the reciprocating motion unit is as follows.

[0056] refer to Figure 14 、 17 ,in, Figure 17 The three-dimensional structural diagram of the reciprocating moving unit is shown. As can be seen from the figure, the reciprocating moving unit includes a slide rail 56, which is fixedly connected to the suspension frame 55 and serves as a basic support structure, providing a foundation for the installation and movement guidance of other components. The tooth plate 57 is slidably connected to the slide rail 56, and the tooth plate 57 is meshed with the fan gear 54. The linear motion of the tooth plate 57 is achieved through the transmission of the fan gear 54; at the same time, the swing gear 58 is rotatably connected to the bottom of the tooth plate 57 and can move back and forth with the movement of the tooth plate 57. The rack 59 in the slide rail 56 is meshed with the swing gear 58. The electric nozzle 60 is fixedly connected to the corresponding swing gear 58. The spray angle or position is adjusted by the swing of the swing gear 58 to achieve precise operation.

[0057] Combined with the above-mentioned connection relationship, the working principle of the chip removal mechanism is as follows: when the scraper 43 moves, it drives the chain belt 45 to rotate, and the rotating chain belt 45 engages the transmission gear 52 and the eccentric shaft 50 to rotate; the rotating eccentric shaft 50 cooperates with the guide groove 51, and the continuously rotating eccentric shaft 50 can make the swing arm 49 and the fan gear 54 swing continuously left and right; when the fan gear 54 swings left and right, it engages the linkage gear plate 57 and moves back and forth along the slide rail 56; the swinging gear 58 that moves back and forth continuously engages and links with the rack 59, so that the swinging gear 58 and the electric nozzle 60 swing left and right accordingly when they move back and forth continuously.

[0058] By providing a chip removal mechanism, the present invention achieves the following beneficial effects: The chain belt 45 is fixed to the scraper 43 in the transmission unit. The movement of the scraper 43 during operation of the polishing mechanism automatically drives the chain belt 45, eliminating the need for an additional power source and achieving energy conservation and high efficiency. The swing unit, through the coordination of the transmission gear 52, the eccentric shaft 50, and the guide groove 51, converts the rotation of the chain belt 45 into the left and right swinging of the swing arm 49 and the sector gear 54. This results in a sophisticated structural design and stable transmission. The reciprocating unit reciprocates the toothed plate 57 along the slide rail 56. Combined with the meshing linkage of the swing gear 58 and the rack 59, it drives the electric nozzle 60 to both reciprocate and swing left and right, achieving multi-angle and multi-position cleaning, ensuring comprehensive removal of debris from the surface of the NdFeB magnet. The various units (transmission, swing, and reciprocating) work closely together, with the suspension frame 55 and slide rail 56 providing stable support. The overall structure is compact, operation is reliable, and the continuity and stability of the chip removal operation are guaranteed.
