Technical Field
[0001] This invention relates to magnet assembly technology, and in particular to a device for assembling toroidal magnetic materials. Background Technology
[0002] Magnets are a fundamental electronic and electrical component widely used worldwide, primarily in computers, mobile phones, televisions, communications, toys, audio equipment, automation equipment, and MRI. Currently, neodymium iron boron magnets are widely used as high-performance permanent magnets. In the production and processing of electronic products, diaphragms (microphone, headphone, speaker, etc.), and electroacoustic equipment, some equipment requires magnets that are not conventionally rectangular or circular. Depending on the product processing requirements, magnets need to be assembled into a shape and size suitable for the equipment, or a Helbeck array may be used to arrange and combine different magnets according to their required polarities. Existing ring-shaped composite magnets require overcoming the repulsive forces between magnets during assembly, resulting in low efficiency and poor positioning accuracy in the pressing and bonding processes, which cannot meet the needs of mass production. Summary of the Invention
[0003] The purpose of this invention is to provide a ring-shaped magnetic material assembly device to solve the problem of low assembly efficiency in existing ring-shaped composite magnet assemblies.
[0004] To address the aforementioned problems, this invention provides a ring-shaped magnetic material assembly device. The device comprises a cabinet with an inlet and an outlet, and a conveyor belt corresponding to the inlet and outlet installed inside the cabinet. The device is characterized by further comprising multiple pressing assemblies located on both sides of the conveyor belt inside the cabinet, and a robotic arm on the upper side of the conveyor belt for transferring a magnet carrier between the conveyor belt and the pressing assemblies. The magnet carrier has multiple radially arranged grooves, and a central circular groove communicating with the inner end of each groove. Magnets to be assembled are filled into the grooves and can move along the grooves to the central circular groove. The support plate of the pressing assemblies has a positioning groove at its center for placing the magnet carrier. The support plate also has multiple pushing rods corresponding to each groove on the magnet carrier. When each pushing rod moves synchronously inward within its corresponding groove, it pushes the magnet in the groove towards the center of the magnet carrier and presses it into a ring-shaped magnet.
[0005] The annular magnetic material assembly equipment provided by this invention also has the following technical features:
[0006] Furthermore, the lower side of the support plate is provided with a drive disk that drives each of the push rods to move synchronously. The central axis of the drive disk coincides with the central axis of the magnet carrier. The drive disk is provided with a drive groove, and the push rod is provided with a lever that extends downward into the drive groove. When the drive disk reciprocates, it can drive each of the push rods to move synchronously back and forth in the groove.
[0007] Furthermore, a rotary cylinder for driving the drive disk to reciprocate is also installed on the lower side of the drive disk.
[0008] Furthermore, the support plate is also provided with a first slide rail corresponding to each of the push rods, a first slider is installed on the first slide rail, the push rod is installed on the first slider, and the first slider is provided with a lever that extends downward into the drive groove.
[0009] Furthermore, a second slide rail is also installed on the first slider, and a second slider is installed on the second slide rail. The push rod is installed on the second slider. The first slider is also provided with a vertical plate corresponding to the outer end of the second slide rail, and a buffer spring is installed between the vertical plate and the second slider.
[0010] Furthermore, the end of the push rod is provided with an arc-shaped groove that matches the outer contour of the magnetic block.
[0011] Furthermore, the magnet carrier is cylindrical, and the groove is provided on the upper surface of the magnet carrier; clamping and positioning parts are also symmetrically provided on the side of the magnet carrier.
[0012] Furthermore, the magnet carrier is also provided with vertical vent holes corresponding to the docking points of adjacent magnetic blocks after each magnetic block is pressed and assembled.
[0013] Furthermore, a pressure-holding bracket is also installed inside the cabinet, which is parallel to the conveyor belt. The pressure-holding bracket is located on the upper side of the pressing assembly. A pressure-holding cylinder corresponding to each pressing assembly is installed on the pressure-holding bracket. The telescopic rod end of the pressure-holding cylinder faces downward and is equipped with a pressure-holding cover plate. The bottom of the pressure-holding cover plate is provided with radial protrusions corresponding to the sliding groove of the magnet carrier. The inner ends of the plurality of radial protrusions form circular grooves that are adapted to the outer contour of the annular magnet.
[0014] Furthermore, the pressure-holding cover plate is also provided with an exhaust hole.
[0015] Furthermore, a connecting plate is installed at the end of the telescopic rod of the pressure-holding cylinder, and an elastic mounting plate is installed on the lower side of the connecting plate.

[0016] Furthermore, the lower side of the pressing assembly is provided with a push cylinder perpendicular to the conveyor belt, the push cylinder being used to push the pressing assembly toward the conveyor belt and away from the pressure-holding bracket.
[0017] The present invention has the following beneficial effects: In the process of assembling magnetic blocks into a ring magnet, the magnetic blocks are first filled into the grooves on the magnet carrier, and glue is applied to the side of each magnetic block. Then, the magnet carrier filled with magnetic blocks is placed on the conveyor belt through the feed port on the cabinet. The magnet carrier enters the cabinet with the conveyor belt and moves to the preset position. Then, the robot moves the magnet carrier on the conveyor belt to the positioning groove in the center of the support plate of the pressing assembly. Then, the pressing rods of the pressing assembly move synchronously and extend into the grooves, pushing each magnetic block towards the center of the magnet carrier. When each magnetic block moves to the central circular groove on the magnet carrier, the two sides of the adjacent magnetic blocks are spliced together to form a ring magnet. This allows for fast and efficient magnet assembly, meeting the needs of mass production. When the pressing assembly pushes and combines the magnetic blocks, the magnetic block position is accurate, and the finished product has good consistency. Attached Figure Description

[0029] The present invention will be described in detail below with reference to the accompanying drawings and embodiments. It should be noted that, unless otherwise specified, the embodiments and features described in the embodiments of the present invention can be combined with each other.
[0030] like Figures 1 to 11In the embodiment of the annular magnetic material assembly equipment of the present invention shown, the cabinet 10 of the annular magnetic material assembly equipment is provided with an inlet 101 and an outlet. A conveyor belt 20 corresponding to the inlet 101 and the outlet is installed inside the cabinet 10. Multiple sets of pressing components 30 located on both sides of the conveyor belt 20 are also provided inside the cabinet 10. A robotic arm 40 is also provided on the upper side of the conveyor belt 20. The robotic arm 40 is used to transfer a magnet carrier 50 between the conveyor belt 20 and the pressing components 30. The magnet carrier 50 is provided with multiple radially arranged sliding grooves 51. The center of the device 50 is provided with a central circular groove 52 that communicates with the inner end of each slide 51. The magnetic block 61 to be assembled is filled in the slide 51 and can move along the slide 51 to the central circular groove 52. The center of the support plate 31 of the pressing assembly 30 is provided with a positioning groove for placing the magnet carrier 50. The support plate 31 is also provided with a plurality of push rods 32 that correspond to each slide 51 on the magnet carrier 50. When each push rod 32 moves inward synchronously in the corresponding slide 51, it pushes the magnetic block 61 in the slide 51 toward the center of the magnet carrier 50 and presses it into a ring magnet 60. Specifically, in the process of assembling the magnetic blocks 61 into the ring magnet 60, the magnetic blocks 61 are first filled into the grooves 51 on the magnet carrier 50, and glue is applied to the side of each magnetic block 61. Then, the magnet carrier 50 filled with magnetic blocks 61 is placed on the conveyor belt 20 through the feed port 101 on the cabinet 10. After the magnet carrier 50 enters the cabinet 10 with the conveyor belt 20 and moves to the preset position, the robot arm 40 transfers the magnet carrier 50 on the conveyor belt 20 to the support plate 3 of the pressing assembly 30. The magnetic blocks 61 are positioned in the center of the positioning groove; then, each push rod 32 of the pressing assembly 30 moves synchronously into each slide groove 51 and pushes each magnetic block 61 toward the center of the magnet carrier 50. When each magnetic block 61 moves to the center circular groove 52 on the magnet carrier 50, the two sides of the adjacent magnetic blocks 61 are spliced together to form a ring magnet 60. This allows for rapid and efficient magnet assembly, meeting the needs of mass production. When the pressing assembly pushes and combines the magnetic blocks, the magnetic block positions are accurately positioned, and the finished products have good consistency.
[0031] In one embodiment of this application, preferably, the lower side of the support plate 31 is also provided with a drive disk 33 for driving each push rod 32 to move synchronously. The central axis of the drive disk 33 coincides with the central axis of the magnet carrier 50. The drive disk 33 is provided with a drive groove 331, and the push rod 32 is provided with a lever 321 that extends downward into the drive groove 331. When the drive disk 33 reciprocates, it can drive each push rod 32 to move synchronously in the slide groove 51.
[0032] Specifically, after the robot arm 40 transfers the magnet carrier 50 on the conveyor belt 20 to the pressing assembly 30, the magnet carrier 50, filled with the magnetic blocks 61 to be assembled, is located in the positioning groove at the center of the support plate 31. The drive disc 33 rotates under the drive of the drive unit and drives each push rod 32 to move synchronously towards the center of the pressing assembly 30. Each push rod 32 extends into the corresponding slide groove 51 and pushes the magnetic blocks 61 in the slide groove 51 towards the center of the magnet carrier 50. When the magnetic blocks 61 move to the inner end of the slide groove 51, the adjacent magnetic blocks 61 dock with each other to form a ring magnet, thereby quickly and reliably completing the assembly of the ring magnet. After the magnet assembly is completed, the drive disc 33 rotates in the opposite direction under the drive of the drive unit and drives each push rod 32 to move synchronously towards the outside of the pressing assembly 30 and detach from the magnet carrier 50. After the magnet assembly is completed, the robot arm 40 transfers the magnet carrier to the conveyor belt 20, and the magnet carrier is transferred to the next process through the discharge port on the cabinet 10 via the conveyor belt 20. like Figure 2 As shown, this application has multiple pressing components 30. The robot arm 40 can transfer the magnet carrier between the conveyor belt 20 and each pressing component 30 according to the control requirements, thereby enabling efficient material transfer and magnet assembly.
[0033] In one embodiment of this application, preferably, a rotary cylinder 34 is also installed on the lower side of the drive disk 33 to drive the drive disk 33 to reciprocate, thereby driving the drive disk 33 to reciprocate.
[0034] In one embodiment of this application, preferably, the support plate 31 is further provided with a first slide rail 311 corresponding to each push rod 32, a first slider 312 is installed on the first slide rail 311, the push rod 32 is installed on the first slider 312, and the first slider 312 is provided with a lever 321 extending downward into the drive groove 331; specifically, the support plate 31 is provided with a through hole corresponding to the movement trajectory of the lever 321, and the lever 321 passes downward through the support plate 31 and then inserts into the drive groove 331 on the drive disc 33; by setting the first slide rail and the first slider, the push rod can reliably and stably slide in reciprocating motion.
[0035] In one embodiment of this application, preferably, a second slide rail 313 is also installed on the first slider 312, a second slider 314 is installed on the second slide rail 313, and a push rod 32 is installed on the second slider 314; the first slider 312 is also provided with a vertical plate 315 corresponding to the outer end of the second slide rail 313, and a buffer spring 316 is installed between the vertical plate 315 and the second slider 314; by setting the second slide rail, the second slider, and the buffer spring, the impact is reduced when the end of the push rod 32 abuts against the magnetic block 61, the damage to the magnetic block is reduced, and it can be ensured that each push rod 32 reliably presses the magnetic block 61, thereby improving the reliability of the pressing assembly.
[0036] In one embodiment of this application, preferably, the end of the push rod 32 is provided with an arc-shaped groove that matches the outer contour of the magnetic block 61; specifically, each magnetic block 61 is fan-shaped, and after each magnetic block 61 moves toward the center of the magnet carrier 50 and docks, it forms a ring-shaped annular magnet 60. The arc-shaped groove at the end of the push rod 32 matches the outer contour of the magnetic block 61, which can reliably push the magnetic block 61 to move toward the center of the magnet carrier 50 in the slide groove 51, preventing the magnetic block 61 from flipping over during the movement.
[0037] In one embodiment of this application, preferably, the magnet carrier 50 is cylindrical, and a groove 51 is disposed on the upper surface of the magnet carrier 50; clamping and positioning portions 53 are also symmetrically provided on the side of the magnet carrier 50. Preferably, the magnet carrier 50 is also provided with vertical vent holes 54 corresponding to the mating points of adjacent magnet blocks 61 after each magnet block 61 is pressed and assembled. Specifically, when magnet blocks 61 are filled into the groove 51 on the magnet carrier 50, such as Figure 9 As shown, an auxiliary cover plate 55 is also used. The auxiliary cover plate 55 has multiple magnetic block mounting holes 551 that correspond to each slide groove 51. The shape of the magnetic block mounting holes 551 is adapted to the shape of the magnetic block 61, so that the magnetic blocks can be filled quickly and accurately. When assembling the magnetic blocks, the auxiliary cover plate 55 is first fastened to the upper side of the magnet carrier 50. Then, the magnetic blocks 61 are filled into the slide groove 51 through the magnetic block mounting holes 551 by a robot or manually. After each magnetic block 61 is filled into the corresponding slide groove 51, the auxiliary cover plate 55 is removed. Then, glue is applied to the side of each magnetic block 61. Then, the magnet carrier 20 after filling the magnetic blocks 61 is transferred to the conveyor belt 20 through the inlet 101 of the cabinet 10, thus starting the automated pressing and assembly.
[0038] In one embodiment of this application, preferably, a pressure-holding bracket 70 is also installed inside the cabinet 10, which is parallel to the conveyor belt 20. The pressure-holding bracket 70 is located on the upper side of the pressing assembly 30. A pressure-holding cylinder 71 corresponding to each pressing assembly 30 is installed on the pressure-holding bracket 70. The telescopic rod end of the pressure-holding cylinder 71 faces downward and is equipped with a pressure-holding cover plate 72. The bottom of the pressure-holding cover plate 72 is provided with radial protrusions 721 corresponding to the sliding groove 51 of the magnet carrier 50. The inner ends of the plurality of radial protrusions 721 form circular grooves 722 that are adapted to the outer contour of the annular magnet 60. Preferably, the pressure-holding cover plate 72 is also provided with an exhaust hole 723. Specifically, in one embodiment of this application, the pressing rod 32 of the pressing assembly 30 pushes the magnetic block 61 in the groove 51 of the magnet carrier 50 inward to press it into an annular magnet 60. The sides of adjacent magnetic blocks 61 are bonded together by the adhesive. At this time, the pressure holding cover 72 moves downward under the action of the pressure holding cylinder and presses the pressure holding cover 72 onto the upper side of the magnet carrier 50. The pressing rod 32 and the pressure holding cover 72 work together to press the annular magnet 60 for a predetermined time, so that the adhesive firmly bonds the magnetic block 61. After the pressing is completed, the pressing rod 32 and the pressure holding cover 72 are simultaneously removed from the magnet carrier 50. Then, the robot arm 40 transfers the magnet carrier 50 that has completed the pressing operation to the conveyor belt, thereby making the pressing assembly reliable, firm and efficient.
[0039] In one embodiment of this application, preferably, a connecting plate 73 is also installed at the end of the telescopic rod of the pressure-holding cylinder 71, and an elastic mounting plate 74 is installed on the lower side of the connecting plate 73. The pressure-holding cover plate 72 is installed on the lower side of the elastic mounting plate 74. A guide rod 731 and a buffer spring 732 are provided between the connecting plate 73 and the elastic mounting plate 74, thereby preventing the pressure-holding cover plate 72 from colliding with and impacting the magnet carrier 50 and the annular magnet 60 when it moves downward, and reliably pressing the annular magnet 60, thereby improving the reliability of the pressing assembly.
[0040] In one embodiment of this application, preferably, a pushing cylinder 35 for the vertical conveyor belt 20 is also provided on the lower side of the pressing assembly 30. The pushing cylinder 35 is used to push the pressing assembly 30 toward the conveyor belt 20 and away from the pressure holding bracket 70. Specifically, when the magnet carrier 50 is not placed on the pressing assembly 30, the pressing assembly 50 is located between the conveyor belt 20 and the pressure holding bracket 70, thereby facilitating the robot arm 40 to transfer the magnet carrier 50 to the pressing assembly 30. After the robot arm 40 transfers the magnet carrier 50 to the pressing assembly 30, the pushing cylinder 35 moves the pressing assembly 30 to the lower side of the pressure holding bracket 70, so that the magnet carrier 50 is aligned with the pressure holding cover plate 72, thereby facilitating the pressure holding cover plate 72 to move from top to bottom for pressing operations. After the pressing operations are completed, the pushing cylinder 35 is used to push the pressing assembly 30 toward the conveyor belt 20 and away from the pressure holding bracket 70, thereby facilitating the removal and placement of the magnet carrier.
[0041] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention, and not to limit them; although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features; and these modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the spirit and scope of the technical solutions of the embodiments of the present invention.
