Abstract
Description
Technical Field
[0001] This invention relates to the field of magnetization equipment technology, and more specifically, to a magnetization mechanism for magnets. Background Technology
[0002] In the production and application of permanent magnet materials, magnetization is one of the key technological steps. Currently, the most common method for magnetization in industry is batch stacking magnetization, where multiple magnets are stacked together and fed into the magnetization equipment for magnetization. However, this method has significant drawbacks in practice: because the magnets possess strong magnetism after magnetization, adjacent magnets tend to adhere tightly to each other due to magnetic force, making them difficult to separate. This adhesion not only increases the difficulty of manual or mechanical separation but also easily causes scratches on the magnet surface, damages magnetic properties, and can even hinder subsequent automated assembly processes, seriously affecting production efficiency and product quality.
[0003] In view of this, the applicant hereby submits this application after studying the existing technology. Summary of the Invention

Obviously, the described embodiments are only a part of the embodiments of the present invention, not all of them. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without inventive effort are within the scope of protection of the present invention. Therefore, the following detailed description of the embodiments of the present invention provided in the accompanying drawings is not intended to limit the scope of the claimed invention, but merely represents selected embodiments of the invention. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without inventive effort are within the scope of protection of the present invention.
[0018] like Figure 1-4 As shown, the present invention provides a magnetizing mechanism for magnets, mainly comprising a transmission component and a magnetizing box 2. The transmission component includes a ring-shaped transmission chain 1, a drive component for driving the transmission chain 1 to rotate, and tooling parts 3 evenly spaced around the transmission chain 1. The tooling parts 3 are used to individually carry the magnets to be magnetized; one side of the transmission chain 1 passes through the interior of the magnetizing box 2 in a straight section, allowing the magnet to complete the magnetization process as it passes through this area. The magnetizing box is an existing technology, and different tooling structures are used for different magnets, which will not be elaborated here. A loading area 4 is provided on the side of the transmission chain 1 near the inlet end 23 of the magnetizing box 2, and a unloading area 5 is provided on the side near the outlet end 24 of the magnetizing box 2. The entire mechanism drives the transmission chain 1 to circulate along a closed-loop path via the drive component, causing each tooling part 3 to sequentially pass through the loading area 4, the magnetizing box 2, and the unloading area 5, thereby achieving automatic loading, magnetization, and unloading of the magnets.
[0019] The drive assembly includes a support base 6, transmission gears 7, and a drive motor 8. Two transmission gears 7 mesh with the two ends of the transmission chain 1 and are rotatably connected to the corresponding support bases 6 via bearings. The drive motor 8 is fixedly mounted on one of the support bases 6, and its output shaft is connected to the axle of the corresponding transmission gear 7 via a reducer, thereby driving the transmission gear 7 to rotate and thus driving the entire transmission chain 1 to circulate in a predetermined direction.
[0020] Preferably, to ensure the tension of the transmission chain 1 during long-term operation, this mechanism also includes two sets of tensioning components, located on both sides of the magnetizing box 2. The tensioning components include an adjusting plate 9, a connecting shaft 10, and a tensioning wheel 11. The tensioning wheel 11 is rotatably connected to the connecting shaft 10 via rolling bearings. The connecting shaft 10 is slidably installed in the elongated adjusting hole of the adjusting plate 9 and fixed in position by a locking nut or set screw. The tensioning wheel 11 engages with the non-working side link of the transmission chain 1, applying a downward clamping force. When the transmission chain 1 becomes loose due to long-term operation, the operator loosens the locking mechanism and moves the connecting shaft 10 along the adjusting hole, causing the tensioning wheel 11 to advance towards the transmission chain 1 until the chain regains appropriate tension, and then re-locks it. This structure ensures that the transmission chain 1 maintains constant tension during high-speed or continuous operation, avoiding slippage, misalignment, or positioning deviation of the tooling 3 caused by loosening.
[0021] Preferably, the transmission chain 1 is arranged in a longitudinal loop, forming a closed-loop running path in the vertical plane. The straight section of its upward segment passes through the magnetizing box 2, and the downward segment passes through the bottom of the magnetizing box 2. This layout arranges the main moving parts of the equipment along the height direction, significantly reducing the projected area in the horizontal direction. It is suitable for space-constrained automated production line environments and facilitates compact docking with other process equipment.
[0022] Preferably, a feeding rack 12 is fixed on one side of the inlet end 23 of the magnetizing box 2, and a feeding trough 13 is provided on the feeding rack 12. The opening of the feeding trough 13 faces the running trajectory of the tooling component 3 of the transmission chain 1, so that the external feeding mechanism can send the magnet to be magnetized along the feeding trough 13 to the positioning area of the tooling component 3. The two side walls of the feeding trough 13 provide lateral restraint for the magnet to prevent it from deflecting or tipping over during the pushing process, ensuring that the magnet falls accurately into the designated position of the tooling component 3.
[0023] Preferably, a feeding rack 14 is fixedly provided on one side of the outlet end 24 of the magnetizing box 2, and a feeding groove 15 is provided on the feeding rack 14. The magnet passes through the feeding groove 15, which facilitates positioning by the external feeding mechanism.
[0024] Furthermore, to improve the feeding accuracy, this mechanism also includes a calibration component. The calibration component includes a gripper cylinder 16 and two grippers 17, with the two grippers 17 respectively mounted on the two output ends of the gripper cylinder 16. Through slots 18 are provided on both sides of the feeding trough 15. The gripper cylinder 16 is supported by a bracket below the feeding frame 14. When the magnet passes through the feeding trough 15, the gripper cylinder 16 drives the two grippers 17 to pass through the through slots 18 from both sides of the feeding frame 14 and extend into the feeding trough 15. The inner surfaces of the two grippers 17 move towards each other, applying clamping force to the left and right sides of the magnet, pushing it to the central symmetrical position of the feeding trough 15. After calibration, the gripper cylinder 16 retracts, and the grippers 17 exit the feeding trough 15, providing standard picking coordinates for external feeding mechanisms (such as a three-axis robot), avoiding gripping failure or collisions with equipment due to magnet misalignment.
[0025] The transmission chain 1 includes a connector 19, which connects the chain shaft 20 of the transmission chain 1 to the tooling component 3, and the connector 19 has an L-shaped structure. Specifically, the transmission chain 1 is composed of multiple standard roller chain links hinged together in sequence; the specific structure is not described in detail here. The two ends of the chain shaft 20 protrude beyond the outer chain plate. A vertical section of each of the two L-shaped connectors 19 is fitted onto the two protruding ends of the chain shaft 20 and fixed by nuts or snap rings. The horizontal section extends outward perpendicular to the running direction of the transmission chain 1 and is provided with mounting holes or positioning pins for fixing the tooling component 3. The tooling component 3 is a rectangular block structure, and its upper surface has grooves or positioning bosses that match the shape of the magnet, ensuring that the magnet maintains a stable posture during transmission and magnetization. This cantilevered connection structure keeps the tooling component 3 away from the chain body, making it easier for the feeding mechanism to approach the magnet from above or the side, while avoiding interference from the chain movement to the magnet.
[0026] In addition, a loading detection unit 21 and a unloading detection unit 22 are respectively provided in the loading area 4 and the unloading area 5. The loading detection unit 21 is a photoelectric sensor or proximity switch, installed near the loading rack 12. Its detection beam or sensing area covers the position of the magnet when the tooling 3 passes through the loading area 4. When the tooling 3 arrives at the loading area 4, if the sensor does not detect the presence of the magnet, it is determined that the loading has failed. The control system suspends the chain operation or issues an alarm signal to prevent the unloaded tooling 3 from entering the magnetization box 2, thus avoiding energy waste or equipment malfunction. The unloading detection unit 22 is also a photoelectric sensor or vision recognition module, installed at the exit of the unloading rack 14. It is used to detect whether the magnet is discharged and cooperates with the external unloading mechanism to discharge the magnet, providing real-time feedback on the station status.
[0027] Throughout the operation, since each magnet is supported by an independent tooling 3 and adjacent tooling 3 are spaced apart, the magnets do not have physical contact with each other during the magnetization process. Therefore, after magnetization, they will not attract each other due to magnetic force, which makes it easier for subsequent robotic arms or conveying devices to accurately grasp them and effectively solves the separation difficulties caused by traditional stacking magnetization methods. Meanwhile, the longitudinally circulating transmission chain 1 significantly reduces the horizontal footprint of the equipment, improving space utilization; the loading trough 13 and unloading trough 15 provide guiding and positioning functions, working with the correction component to center and clamp the unloading magnets; the tensioning component, through the cooperation of the adjustable connecting shaft 10 and the tensioning wheel 11, achieves precise adjustment of the tension of the transmission chain 1, ensuring that the chain maintains stable tension during continuous operation; the loading detection unit 21 and the unloading detection unit 22 constitute a dual monitoring mechanism, judging the status of the tooling 3 in real time, preventing no-load magnetization or abnormal retention, and improving the reliability and safety of system operation; the modular design of the L-shaped connector 19 and the tooling 3 facilitates quick replacement of tooling of different specifications, adapting to the magnetization needs of magnets of various sizes, and improving the versatility of the equipment.
[0028] In summary, this invention, through structural innovation and functional integration, solves the core technical challenge of separating magnets after magnetization, achieving a complete closed-loop process encompassing isolated magnetization, automatic loading and unloading, precise positioning, and process monitoring. The connections between its components are clearly defined, the operational logic is clear, and the technical solution is concrete and implementable. Those skilled in the art can manufacture and operate this mechanism based on the invention's content, demonstrating outstanding practicality and industrial application value.

Various modifications and variations can be made to the invention by those skilled in the art. Any modifications, equivalent substitutions, or improvements made within the spirit and principles of the invention should be included within the scope of protection of the invention.
