Description

Technical Field

[0001] This utility model relates to magnet assembly technology, and in particular to a lifting and rotating mechanism for magnet assembly. Background Technology

[0002] Magnets are widely used basic electronic and electrical components, primarily found 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 shapes. Depending on the product processing requirements, magnets need to be assembled into a shape and size suitable for the specific equipment.

[0003] For example, the magnetic ring assembly disclosed in the Chinese utility model patent document "CN202222384665.X A magnetic component and a magnetic ring assembly having the magnetic component" has multiple fan-shaped magnetic blocks arranged in a ring structure. When assembling such a ring-shaped combined magnet, multiple fan-shaped magnetic blocks need to be placed on an assembly table in a ring according to a preset position to form a ring. The assembly table needs to be rotated during the placement of each fan-shaped magnetic block, resulting in poor reliability of the existing structure. The poor positioning accuracy during the rotation of the assembly table leads to inaccurate placement of the magnetic blocks. Utility Model Content

[0004] The purpose of this utility model is to provide a lifting and rotating mechanism for assembling magnets, which solves the problems of poor reliability and poor positioning accuracy of existing rotating mechanisms for assembling magnets.

[0005] To address the aforementioned problems, this utility model provides a lifting and rotating mechanism for assembling magnets, comprising a rotating disk mounted on a support platform. The rotating disk has a central mounting hole, within which a downwardly extending support shaft is installed. The support shaft is mounted on the support platform. A first motor connected to the support shaft and used to drive the rotating disk to rotate is mounted on the lower side of the support platform. Multiple rotatable material carriers are evenly distributed along the edge of the rotating disk. Each material carrier has an annular material loading groove on its upper side and a central rotating shaft on its lower side. The lower end of the central rotating shaft passes downward through the rotating disk and is fitted with a locking block. A rotating assembly located below the rotating disk and corresponding to the locking block, is also mounted on the support platform to drive the material carriers to rotate. The rotating assembly includes a second motor capable of vertical lifting. The output shaft of the second motor faces upward and is fitted with a lifting connecting block. When the second motor rises, the lifting connecting block engages with the locking block, allowing the second motor to drive the material carriers to rotate via the locking block.

[0006] The lifting and rotating mechanism for assembling magnets provided by this utility model also has the following technical features:

[0007] Furthermore, the rotating assembly also includes a base plate and a top plate. Two lifting cylinders are mounted on the base plate. The extension rods of the lifting cylinders face upward and the top plate is mounted at their ends. The second motor is mounted on the top plate.

[0008] Furthermore, the second motor is installed on the lower side of the top plate with its output shaft facing upward. The top plate has a central hole corresponding to the output shaft of the second motor. The lifting connecting block can rotate within the central hole with the output shaft of the second motor and its upper end extends upward out of the top plate.

[0009] Furthermore, the base plate is also equipped with limiting plates located on both sides of the top plate, and the top of the limiting plates is provided with a baffle extending toward the center of the top plate and located on the upper side of the top plate.

[0010] Furthermore, the lower side of the snap-fit ​​block is provided with two snap-fit ​​holes, and the top of the lifting connecting block is provided with a snap-fit ​​pin corresponding to the snap-fit ​​holes. When the lifting connecting block moves upward, the snap-fit ​​pin is inserted into the snap-fit ​​hole.

[0011] Furthermore, a positioning plate is also installed on the side of the lifting connecting block, and a position detection sensor corresponding to the positioning plate is installed on the top plate to detect the position of the positioning plate.

[0012] This utility model has the following beneficial effects: The lifting and rotating mechanism for magnet assembly of this application allows the rotating disk to rotate a predetermined angle on the support platform under the drive of the first motor, so that the material carrier on the rotating disk is sequentially positioned at the corresponding process positions, such as... Figure 1 , Figure 2 As shown, the rotating disk positions each material carrier sequentially on the upper side of the rotating assembly. Multiple rotating assemblies are mounted on the support platform, each corresponding to a material carrier at a specific process position. After the second motor of the rotating assembly rises, the lifting connecting block on the motor output shaft engages with the locking block of the material carrier. Thus, the second motor can drive the material carrier to rotate at a preset angle, facilitating the sequential placement of the magnetic blocks to be assembled into the material slots on the material carrier. This lifting and rotating mechanism for magnetic assembly has a reasonable layout, reliable rotation, and can accurately control the rotation angle of the rotating disk and the material carrier, enabling convenient, efficient, and accurate loading of the magnetic blocks to be assembled onto the material carrier.

[0020] 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 in the embodiments of the present invention can be combined with each other.

[0021] like Figures 1 to 2 In the embodiment of the magnet assembly lifting and rotating mechanism of this utility model shown, the magnet assembly lifting and rotating mechanism includes a rotating disk 20 mounted on a support platform 10. The rotating disk 20 has a mounting hole 201 at its center, and a downwardly extending support shaft (not shown in the figure) is installed in the mounting hole 201. The support shaft is mounted on the support platform 10 and is rotatable. A first motor (not shown in the figure) connected to the support shaft and used to drive the support shaft and the rotating disk 20 to rotate is mounted on the lower side of the support platform 10. Multiple rotatable material carriers 30 are evenly distributed along the edge of the rotating disk 20. The upper side of the material carrier 30... The loading platform 30 is provided with an annular loading trough. A central rotating shaft 31 is provided on the lower side of the loading platform 30. The lower end of the central rotating shaft 31 passes downward through the rotating disk 20 and is equipped with a locking block 32. A rotating component 40 is also installed on the support platform 10, located on the lower side of the rotating disk 20 and corresponding to the locking block 32, for driving the loading platform 30 to rotate. The rotating component 40 includes a second motor 41 that can be raised and lowered. The output shaft of the second motor 41 faces upward and is equipped with a lifting connecting block 42. When the second motor 41 rises, the lifting connecting block 42 engages with the locking block 32. The second motor 41 can drive the loading platform 30 to rotate a preset angle through the locking block 32. Specifically, the loading platform 30 rotates by an angle corresponding to one sector magnetic block each time, thereby sequentially filling each sector magnetic block into the loading trough.

[0022] The lifting and rotating mechanism for magnet assembly in the above embodiments of this application allows the rotating disk to rotate a predetermined angle on the support platform under the drive of a first motor, so that the material carrier on the rotating disk is sequentially positioned at the corresponding process positions, such as... Figure 1 , Figure 2 As shown, the rotating disk positions each material carrier sequentially on the upper side of the rotating assembly. Multiple rotating assemblies are mounted on the support platform, each corresponding to a material carrier at a specific process position. After the second motor of the rotating assembly rises, the lifting connecting block on the motor output shaft engages with the locking block of the material carrier. Thus, the second motor can drive the material carrier to rotate at a preset angle, facilitating the sequential placement of the magnetic blocks to be assembled into the material slots on the material carrier. This lifting and rotating mechanism for magnetic assembly has a reasonable layout, reliable rotation, and can accurately control the rotation angle of the rotating disk and the material carrier, enabling convenient, efficient, and accurate loading of the magnetic blocks to be assembled onto the material carrier.

[0023] In one embodiment of this application, preferably, as shown below, Figure 3 , Figure 4 As shown, the rotating assembly 40 also includes a base plate 43 and a top plate 44. Two lifting cylinders 46 are installed on the base plate 43. The telescopic rods of the lifting cylinders 46 face upward and the top plate 44 is installed at their ends. A second motor 41 is installed on the top plate 44. When the telescopic rods of the lifting cylinders 46 extend upward, the second motor 41 moves upward with the top plate 44 and the lifting connecting block 42 engages with the locking block 32. When the telescopic rods of the lifting cylinders 46 retract upward, the second motor 41 moves downward with the top plate 44, causing the lifting connecting block 42 to separate from the locking block 32. The loading platform 30 can rotate with the rotating disk 20 without being affected by the rotating assembly 40.

[0024] In one embodiment of this application, preferably, the second motor 41 is mounted on the lower side of the top plate 44 with its output shaft facing upwards. The top plate 44 has a central hole corresponding to the output shaft of the second motor 41. The lifting connecting block 42 can rotate within the central hole with the output shaft of the second motor 41, and the upper end of the lifting connecting block 42 extends upwards out of the top plate 44. Figure 5 As shown, the housing of the second motor 41 is provided with a mounting hole 411 for connection and fixation with the top plate 44, making it convenient to connect the second motor 41 to the top plate 44.

[0025] In one embodiment of this application, preferably, a limiting plate 45 located on both sides of the top plate 44 is also installed on the bottom plate 43. The top of the limiting plate 45 is provided with a baffle 451 extending toward the center of the top plate 44 and located on the upper side of the top plate 44 to limit the rising height of the top plate 44, so that the lifting connecting block 42 and the snap-fit ​​block 32 are reliably snapped together.

[0026] In one embodiment of this application, preferably, the lower side of the snap-fit ​​block 32 is provided with two snap-fit ​​holes 321, and the top of the lifting connecting block 42 is provided with a snap pin 421 corresponding to the snap-fit ​​holes 321. When the lifting connecting block 42 moves upward with the top plate 44, the snap pin 421 is inserted into the snap-fit ​​hole 321, so that the snap-fit ​​block 32 can rotate with the lifting connecting block 42.

[0027] In one embodiment of this application, preferably, a positioning piece 422 is also installed on the side of the lifting connecting block 42, and a position detection sensor 441 corresponding to the positioning piece 422 is installed on the top plate 44 to detect the position of the positioning piece 422.

[0028] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model, and not to limit it. Although this utility model 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. Such 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 this utility model.
