Description

Technical Field

[0001] This utility model relates to the field of magnet assembly technology, specifically to a magnetic plate assembly fixture, a magnetic plate processing system, and a magnetic levitation device. Background Technology

[0002] In the field of precision manufacturing of magnetic levitation movers, the high-precision installation of magnet arrays is the core link to ensure the performance of the mover. Currently, the process requires fixing multiple permanent magnets, such as neodymium iron boron magnets, at a preset interval on a non-magnetic mounting plate, such as an aluminum alloy or carbon fiber plate, to form a regular magnetic field distribution. However, the installation offset problem caused by the strong magnetic force between the magnets has become a key bottleneck restricting production efficiency and product precision.

[0003] During the assembly process, the attractive or repulsive forces between adjacent magnetic poles can reach tens of Newtons, which can cause the magnets to deviate from their designed positions. In conventional processing, when the magnets are arranged with their N poles in the same direction, the repulsive force between adjacent magnets may cause them to shift laterally by more than 0.3 mm. Magnetic levitation systems typically require the magnet spacing error to be less than ±0.02 mm. This deviation not only disrupts the uniformity of the magnetic field but also causes abnormal vibrations or positioning deviations when the mover is levitated.

[0004] Existing processes require overcoming installation errors by measuring the position of each magnet individually using a visual inspection system, such as an industrial camera, after the magnets are pasted or riveted. A secondary correction is then performed using mechanical clamps or electromagnetic devices. This step requires additional production time, and the aforementioned adjustments can easily introduce new errors. Therefore, there is an urgent need to develop a method or device that can dynamically resist the magnetic forces between magnets during assembly, achieving precise one-time positioning of the magnets and avoiding subsequent correction processes. Summary of the Invention

[0005] Therefore, the technical problem to be solved by this utility model is to overcome the difficulty in positioning the magnet during the processing of magnetic plates in the prior art, and to provide a magnetic plate assembly fixture, a magnetic plate processing system and a magnetic levitation device.

[0006] To solve the above-mentioned technical problems, this utility model provides a magnetic plate assembly fixture, comprising: a carrying mechanism, the carrying mechanism including a base plate, a surrounding plate, and a plurality of blocking blocks, the surrounding plate being arranged around the edge of the base plate and protruding from the base plate, the surrounding plate enclosing a first installation space on the base plate, the mounting plate of the magnet to be connected being embedded in the first installation space, the plurality of blocking blocks being arranged around the surrounding plate and protruding from the surrounding plate, the blocking blocks enclosing a second installation space on the surrounding plate; and at least one partitioning mechanism, the partitioning mechanism including a frame and a plurality of partition strips, the frame being embedded in the second installation space and supported by the surrounding plate, the plurality of partition strips being spaced apart along a first direction to separate a plurality of magnet installation spaces in the frame, the magnet to be connected being embedded in the magnet installation space and connected to the mounting plate.

[0007] In one embodiment of this utility model, the enclosure is provided with at least one first connecting hole, and the frame is provided with at least one second connecting hole. The first connecting hole and the second connecting hole are provided in a one-to-one correspondence. The connector can pass through the first connecting hole and the second connecting hole so that the frame and the enclosure are detachably connected.

[0008] In one embodiment of the present invention, a corner clearance groove is provided at the corner of the enclosure panel. The corner clearance groove is connected to the first installation space and is recessed in a direction away from the first installation space to accommodate the corner of the mounting plate.

[0009] In one embodiment of the present invention, the enclosure further includes a transfer groove, which is disposed on opposite sides of the enclosure and recessed inward from the edge of the enclosure.

[0010] In one embodiment of the present invention, the enclosure is further provided with at least one mounting plate connection hole, which is located on the inner sidewall of the enclosure to be detachably connected to the mounting plate via a connector.

[0016] The above-mentioned technical solution of this utility model has the following advantages compared with the prior art:

[0017] The magnetic plate assembly fixture, magnetic plate processing system, and magnetic levitation device described in this utility model use a carrying mechanism to fix and limit the mounting plate on which the magnets to be connected, and then a blocking mechanism to stop and limit the connection position of the magnets on the mounting plate. This ensures the relative fixation of the magnets' positions on the mounting plate, thereby achieving a high-precision connection between the magnets and the mounting plate. Compared with current processing technologies, this application uses a hard limiting structure to fundamentally avoid the possibility of displacement of the magnets under magnetic influence. At the same time, the high degree of cooperation between the blocking mechanism and the carrying mechanism simplifies the magnetic plate assembly process, thus possessing significant advantages such as flexibility, strong compatibility, ease of operation, and high positioning accuracy.

Detailed Implementation

[0023] The present invention will be further described below with reference to the accompanying drawings and specific embodiments, so that those skilled in the art can better understand and implement the present invention. However, the embodiments are not intended to limit the present invention.

[0024] Example 1:

[0025] This embodiment provides a magnetic plate assembly fixture to assist in the assembly of magnetic plates. In the prior art, a magnetic plate includes a mounting plate 300 and multiple magnets. The multiple magnets are evenly spaced and attached to each other along the length of the magnetic plate. Specifically, before assembly, the magnets need to be coated with an accelerator and an adhesive. Then, the magnets are attached to the corresponding positions on the magnetic plate, and the assembly is completed after the adhesive has stabilized. During the waiting period for the adhesive to stabilize, adjacent magnets will have mutual attraction or repulsion forces due to magnetism, resulting in a shift in the actual installation position of the magnets.

[0026] In view of the above problems, the magnetic plate assembly fixture provided in this application includes:

[0027] The receiving mechanism 100 includes a base plate 110, a surrounding plate 120, and a plurality of retaining blocks 130. The surrounding plate 120 is arranged around the edge of the base plate 110 and protrudes from the base plate 110. The surrounding plate 120 encloses a first installation space on the base plate 110, in which the mounting plate 300 to be connected to the magnet can be embedded. The plurality of retaining blocks 130 are arranged around the surrounding plate 120 and protrude from the surrounding plate 120. The enclosure 120 forms a second installation space; at least one partition mechanism 200: one partition mechanism 200 includes a frame 210 and a plurality of partition strips 220, the frame 210 is embedded in the second installation space and supported by the enclosure 120, the plurality of partition strips 220 are spaced apart along a first direction X to separate a plurality of magnet installation spaces 230 in the frame 210, the magnet to be connected can be embedded in the magnet installation space 230 and connected to the mounting plate 300.

[0028] It should be noted that, for ease of description, in this embodiment, the length direction of the base plate 110 in the magnetic plate assembly fixture is defined as the first direction X, the width direction of the base plate 110 is defined as the second direction Y, and the thickness direction of the base plate 110 is defined as the third direction Z. The first direction X, the second direction Y, and the third direction Z are arranged perpendicularly to each other, and the first direction X and the second direction Y are located in the same plane.

[0029] See Figure 1 and Figure 2As shown, in this embodiment, the base plate 110 is used to support the mounting plate 300. It is preferably a rectangular structure. The surrounding plate 120 is arranged around the edge of the base plate 110. Furthermore, in this embodiment, the surrounding plate 120 surrounds two sides in the width direction (second direction Y) and one side in the length direction (first direction X) of the base plate 110, so as to provide an opening on one side in the length direction (first direction X) of the base plate 110, thereby facilitating the insertion or removal of the mounting plate 300.

[0030] Furthermore, the enclosure 120 is also provided with at least one mounting plate connection hole 124, which is located on the inner sidewall of the enclosure 120, so as to be detachably connected to the mounting plate 300 by means of a connector. Specifically, in this embodiment, the mounting plate connection hole 124 can be connected to the mounting plate 300 by means of bolts or other connectors to further improve the stability of the installation and assembly position.

[0031] Furthermore, in this embodiment, the corner of the enclosure 120 is provided with a corner clearance groove 121. The corner clearance groove 121 communicates with the first mounting space and is recessed in a direction away from the first mounting space to accommodate the corner of the mounting plate 300. Specifically, the corner clearance groove 121 in this embodiment is preferably an arc-shaped groove structure, and the corner of the mounting plate 300 can pass through the corner clearance groove 121, thereby preventing the mounting plate 300 from colliding and being damaged by the enclosure 120 during assembly.

[0032] Furthermore, to facilitate cooperation with external transfer equipment, the enclosure 120 in this embodiment also includes transfer grooves 122, which are disposed on opposite sides of the enclosure 120 and recessed inward from the edge of the enclosure 120. The external transfer equipment is preferably a robotic arm, which includes clamping plates that can be embedded in the two transfer grooves 122, thereby forming a stable clamping structure for the load-bearing mechanism 100.

[0033] In this embodiment, the enclosure block 130 protrudes from the enclosure plate 120 in the third direction Z to limit the position of the partition mechanism 200. Specifically, in this embodiment, the enclosure block 130 covers the four corners of the partition mechanism 200, thereby fixing the partition mechanism 200 from multiple directions. This utility model does not impose specific limitations on the specific number, shape, and placement of the enclosure blocks 130.

[0034] See Figure 1 and Figure 3As shown, in this embodiment, the frame 210 is preferably a rectangular structure that matches the shape of the second installation space. It includes two assembly parts 211 and two connecting parts 212. The two assembly parts 211 are spaced apart along a first direction X, and the two connecting parts 212 are spaced apart and connected to the two ends of the assembly parts 211 along a second direction Y. Each connecting part 212 is connected to both ends of the two assembly parts 211. Specifically, the assembly parts 211 in this embodiment are provided with at least one second connecting hole 213, and the surrounding plate 120 is provided with a first connecting hole 123. The first connecting hole 123 and the second connecting hole 213 are provided in a one-to-one correspondence. The connector can pass through the first connecting hole 123 and the second connecting hole 213 so that the frame 210 and the surrounding plate 120 can be detachably connected. Similarly, the connector is preferably a bolt.

[0035] Furthermore, the assembly part 211 is connected to the enclosure plate 120, and each of the connecting parts 212 is provided with multiple fixing parts 214. The fixing parts 214 of two connecting parts 212 are arranged one-to-one, and the multiple partition bars 220 are respectively fixedly connected to the corresponding fixed parts 214. In this embodiment, the partition bars 220 and the frame 210 are fixedly connected and are actually integrally set to facilitate the production and processing of the partition mechanism 200. In different embodiments, the frame 210 and the partition bars 220 can also be set as a detachable structure to facilitate the adjustment of the size of the magnet installation space 230, thereby further improving the flexibility of the partition mechanism 200.

[0036] In actual production, the size of the magnets and the connection interval can be adaptively adjusted according to actual usage requirements. Therefore, the magnetic plate assembly fixture in this embodiment includes multiple partition mechanisms 200. The size of the magnet installation space 230 in different partition mechanisms 200 is different. Based on this, when different specifications of magnetic plates need to be processed, the assembly of different magnetic plates can be achieved by directly replacing the partition mechanism 200.

[0037] Example 2:

[0038] This embodiment provides a magnetic plate processing system, which includes the magnetic plate assembly fixture described above.

[0039] Example 3:

[0040] This embodiment provides a magnetic levitation device that is compatible with the magnetic plate assembly fixture described in Embodiment 1 and is processed using the magnetic plate assembly fixture.

[0041] In summary, the magnetic plate assembly fixture, magnetic plate processing system, and magnetic levitation device described in this utility model use a carrying mechanism 100 to fix and limit the mounting plate 300 to be connected to the magnet, and then a blocking mechanism 200 to stop and limit the connection position of the magnet on the mounting plate 300. This ensures the relative fixation of the position between the magnet and the mounting plate 300, thereby achieving a high-precision connection between the magnet and the mounting plate 300. Compared with current processing technologies, this application uses a hard limiting structure to fundamentally avoid the possibility of displacement of the magnet under magnetic action. At the same time, the high degree of fit between the blocking mechanism 200 and the carrying mechanism 100 simplifies the magnetic plate assembly process, thus possessing significant advantages such as flexibility, strong compatibility, ease of operation, and high positioning accuracy.

[0042] Obviously, the above embodiments are merely illustrative examples for clear explanation and are not intended to limit the implementation. Those skilled in the art will recognize that other variations or modifications can be made based on the above description. It is neither necessary nor possible to exhaustively list all possible implementations here. However, obvious variations or modifications derived therefrom are still within the protection scope of this invention.
