[0002] Traditional production line equipment relies on belt conveyors and robotic arms to pick up materials and move them from one process module to another for processing. This results in a complex production line layout and low capacity. Summary of the Invention

[0003] This invention aims to at least solve one of the technical problems existing in the prior art. To this end, this invention proposes a magnetic levitation processing device that can simplify production line layout.

[0004] According to an embodiment of the present invention, a magnetic levitation processing equipment has two perpendicular vertical directions, a first horizontal direction, and a second horizontal direction. The magnetic levitation processing equipment includes a frame, a magnetic levitation conveying device, and multiple process modules. The magnetic levitation conveying device includes a stator platform and several moving platforms. The stator platform is connected to the frame and can generate an electromagnetic field. The upper side of the stator platform has a levitation surface. Under the action of the electromagnetic field, each moving platform can levitate above the levitation surface and can reciprocate in the vertical direction, the first horizontal direction, and the second horizontal direction. The moving platforms are used to carry materials. The multiple process modules are all connected to the frame and distributed along the periphery of the levitation surface.

This helps to simplify the production line layout of the magnetic levitation processing equipment and improve material conveying efficiency and production capacity. Furthermore, since the materials are always positioned on the moving platform, there is no need to set up a robotic arm to handle the materials, which helps to improve the processing accuracy of the process modules in processing the materials.

In this specification, the illustrative expressions of the above terms do not necessarily refer to the same embodiment or example. Furthermore, the specific features, structures, materials, or characteristics described may be combined in any suitable manner in one or more embodiments or examples.

[0025] Please see Figures 1 to 3 This application provides a magnetic levitation processing equipment 10. The magnetic levitation processing equipment 10 may have two perpendicular vertical directions Z, a first horizontal direction X and a second horizontal direction Y. The magnetic levitation processing equipment 10 includes a frame 110, a magnetic levitation conveying device 130 and multiple process modules 150.

[0026] The magnetic levitation conveying device 130 includes a stator platform 131 and several moving platforms 133. The stator platform 131 is connected to the frame 110 and can generate an electromagnetic field. The upper side of the stator platform 131 has a suspension surface 1310. Under the action of the electromagnetic field, each moving platform 133 can be suspended above the suspension surface 1310 and can reciprocate along the vertical direction Z, along the first horizontal direction X, and along the second horizontal direction Y. The moving platforms 133 are used to carry materials 30, so that the moving platforms 133 can move flexibly in multiple directions above the suspension surface 1310 to transport the materials 30 to various positions on the suspension surface 1310.

[0027] Multiple process modules 150 are connected to the frame 110 and distributed along the periphery of the suspension surface 1310. The moving platform 133 can sequentially transfer the material 30 to each process module 150 under the drive of the electromagnetic field. Thus, the magnetic levitation conveyor 130 can connect to each process module 150. The moving platform 133 can directly transfer the material 30 to each process module 150 for processing. There is no need to set up a conveyor belt for transporting the material 30 and a robot for handling the material 30 between two adjacent process modules 150. This helps to simplify the production line layout of the magnetic levitation processing equipment 10 and can also improve the material 30 conveying efficiency and production capacity. Furthermore, since the material 30 is always positioned on the moving platform 133, there is no need to set up a robot to handle the material 30, which helps to improve the processing accuracy of the process module 150 in processing the material 30.

[0028] In some embodiments, the moving stage 133 may have a first axis.

[0029] The first axis can be parallel to the vertical direction Z. The moving platform 133 can rotate around the first axis under the action of the electromagnetic field, so that the moving platform 133 and the material 30 can be rotated on the horizontal plane to adjust the placement posture of the material 30 on the horizontal plane. This makes it easier for the subsequent process module 150 to perform more precise processing on the material 30, and there is no need to set up an additional mechanism to move the material 30. This helps to further simplify the production line layout of the magnetic levitation processing equipment 10 and improve the material 30 conveying efficiency and capacity.

[0030] As an example, the upper side of the moving platform 133 may have a bearing surface for bearing material 30. The first axis may intersect with the bearing surface.

[0031] In some embodiments, the moving stage 133 may have a second axis.

[0032] The second axis can be parallel to the first horizontal direction X. The moving platform 133 can rotate around the second axis under the action of the electromagnetic field, thereby flexibly adjusting the angle between the moving platform 133 and the suspension surface 1310, and flexibly adjusting the angle between the material 30 and the suspension surface 1310. This facilitates more precise processing of the material 30 by the subsequent process module 150, and eliminates the need for additional mechanisms to move the material 30. This helps to further simplify the production line layout of the magnetic levitation processing equipment 10 and improve the material 30 conveying efficiency and capacity.

[0033] In some embodiments, the moving stage 133 may have a third axis.

[0034] The third axis can be parallel to the second horizontal direction Y. The moving platform 133 can rotate around the third axis under the action of the electromagnetic field, thereby flexibly adjusting the angle between the moving platform 133 and the suspension surface 1310, and flexibly adjusting the angle between the material 30 and the suspension surface 1310. This facilitates more precise processing of the material 30 by the subsequent process module 150, and eliminates the need for additional mechanisms to move the material 30. This helps to further simplify the production line layout of the magnetic levitation processing equipment 10 and improve the material 30 conveying efficiency and capacity.

[0035] Please see Figures 2 to 4 In some embodiments, the mover stage 133 may include a mover 1330 and a vacuum adsorption carrier 1350.

[0036] In this configuration, the mover 1330 is suspended above the suspension surface 1310 under the influence of an electromagnetic field. The vacuum adsorption carrier 1350 is located above the mover 1330 and connected to it. The vacuum adsorption carrier 1350 is used to carry the material 30. Thus, by setting the vacuum adsorption carrier 1350 on the mover 1330, the material 30 can be stably adsorbed and fixed, which helps to avoid the material 30 from shifting or falling during the movement of the mover platform 133, improves the stability of the material 30 conveying, and helps to ensure the accuracy of subsequent process treatment.

[0037] As an example, the magnetic levitation conveying device 130 may include a magnetic levitation device and a vacuum adsorption carrier 1350. The magnetic levitation device may include a stator platform 131, multiple movers 1330, and a controller. The controller can communicate with the movers 1330 and control the movers 1330 to move and rotate on the levitation surface 1310. The specific working principle of the magnetic levitation device can refer to the prior art, and will not be repeated in this embodiment. The magnetic levitation device can be any known magnetic levitation device that can achieve the purpose of this embodiment. For example, the magnetic levitation device can be a 6-dimensional magnetic levitation device of model M4-09. The upper side of the vacuum adsorption carrier 1350 may have the bearing surface shown in the example above.

[0038] It should be noted that, based on the principles and technologies of existing magnetic levitation devices, those skilled in the art can easily realize the motion of the moving platform 133 around one or any combination of the first axis, the second axis, and the third axis, and the control principle will not be elaborated here.

[0039] In some embodiments, the suspension surface 1310 may have a loading station 1312 and a unloading station 1314, and the multiple process modules 150 may include a first vacuuming module 151 and a first vacuum breaking module 153.

[0040] The first vacuum module 151 is located at the loading station 1312 and connected to the frame 110. The first vacuum breaking module 153 is located at the unloading station 1314 and connected to the frame 110. The remaining process modules 150 are located between the loading station 1312 and the unloading station 1314. The moving platform 133 can move to the loading station 1312 for loading. The first vacuum module 151 extracts the gas from the vacuum adsorption carrier 1350 to create a negative pressure in the vacuum adsorption carrier 1350, which can adsorb and position the material 30 to avoid it from being moved by the moving platform 133. During the process, if the material 30 deviates or falls, the stability of the material 30 conveying is improved, which helps to ensure the accuracy of subsequent processing. The moving platform 133 then sequentially transfers the material 30 to each process module 150 between the loading station 1312 and the unloading station 1314 for processing. The moving platform 133 then transfers the processed material 30 to the unloading station 1314. The first vacuum breaking module 153 can break the vacuum of the vacuum adsorption carrier 1350, and the adsorption force of the vacuum adsorption carrier 1350 on the material 30 disappears, which facilitates the unloading of the material 30.

[0041] In some embodiments, the vacuum adsorption carrier 1350 may include a carrier body 1352 and a control valve 1354.

[0042] The carrier body 1352 can be located above and connected to the mover 1330. The upper side of the carrier body 1352 can have an adsorption surface 1356 for carrying material 30. When the mover platform 133 is at the loading station 1312, material 30 can be placed on the adsorption surface 1356. The carrier body 1352 can be provided with a suction channel 1358, one end of which penetrates the adsorption surface 1356. A control valve 1354 is connected to the carrier body 1352 and is used to open or close the other end of the suction channel 1358. When the mover platform 133 is at the loading station 1312, the first vacuum module 151 can open the control valve 1354 to connect the suction channel 1358, allowing the first vacuum module 151 to extract material from the suction channel 1358. The gas creates a negative pressure in the suction channel 1358, which allows the material 30 to be adsorbed onto the adsorption surface 1356. When the moving carrier 133 is at the unloading station 1314, the first vacuum breaking module 153 can open the control valve 1354, allowing external gas to enter the suction channel 1358 through the control valve 1354, thereby breaking the vacuum in the suction channel 1358. The adsorption force of the vacuum adsorption carrier 1350 on the material 30 disappears, making it easier to unload the material 30.

[0043] As an example, control valve 1354 can be a one-way valve, which can close the end of suction channel 1358 away from adsorption surface 1356. When the moving stage 133 is in the loading position 1312, the connector of the first vacuum module 151 can push against the one-way valve to open the one-way valve and connect the suction channel 1358, so that the first vacuum module 151 can extract gas from the suction channel 1358. When the first vacuum module 151 disengages from the one-way valve, the one-way valve closes the end of suction channel 1358 away from adsorption surface 1356, so that the suction channel 1358 is in a negative pressure state, thereby stably adsorbing material 30. When the moving stage 133 is in the unloading position 1314, the first vacuum breaking module 153 can push against the one-way valve to open the one-way valve, allowing external gas to enter the suction channel 1358, thereby breaking the vacuum in the suction channel 1358.

[0044] Understandably, the adsorption surface can refer to the bearing surface in the above example. The first axis can intersect with the adsorption surface 1356. When the moving stage 133 rotates around the second or third axis, the included angle between the adsorption surface 1356 and the suspension surface 1310 can be adjusted.

[0045] Please see Figures 1 to 3 In some embodiments, the multiple process modules 150 may include a first detection module 155, a first marking module 157, and a second detection module 159.

[0046] The first marking module 157 is located downstream of the first detection module 155, and the second detection module 159 is located downstream of the first marking module 157. The first detection module 155 is used to detect the placement position of the material 30 on the moving platform 133. The first marking module 157 is used to form a first mark on the upper side of the material 30. The second detection module 159 is used to detect the first mark. Thus, the moving platform 133 can sequentially transfer the material 30 to the first detection module 155, the first marking module 157, and the second detection module 159 to perform single-sided marking and detection on the material 30. During this process, the material 30 is always placed on the moving platform 133, and there is no need to move the material 30. This helps to improve the marking accuracy and the material 30 conveying efficiency and capacity.

[0047] When the first detection module 155 detects that the placement position of the material 30 on the moving platform 133 does not match the preset position, the moving platform 133 can move or rotate to drive the material 30 to move or rotate synchronously. This allows for overall adjustment of the posture of the moving platform 133 and the material 30, enabling subsequent process modules 150 to process the material 30 more accurately. Alternatively, the first detection module 155 can detect the placement position of the material 30 on the moving platform 133 and use the current placement position of the material 30 as the target position. Subsequent process modules 150 can then use the target position of the material 30 as a reference for processing the material 30.

[0048] When the second detection module 159 detects a defect in the first identifier, the controller can mark the moving platform 133 carrying the defective material 30 as the target platform. The target platform can still continue to move the material 30 on the suspension surface 1310 according to the original transfer route. The other process modules 150 located downstream of the second detection module 159 no longer need to process the material 30 on the target platform, which helps to reduce the energy consumption of the magnetic levitation processing equipment 10 and can further increase the production capacity.

[0049] As an example, the first marking module 157 can use a laser engraving machine or other marking devices. The first detection module 155 can use a CCD camera or other vision inspection devices. The second detection module 159 can be flexibly configured according to the first identifier. For example, the first identifier can include characters and barcodes. The second detection module 159 can include a CCD camera and a barcode scanning device. The CCD camera is used to detect characters, such as whether the characters are clear or whether there are any missing characters. For example, the characters can include material model, production batch, company name, etc. The barcode scanning device can be used to detect barcodes, such as whether the barcode can be scanned normally, the barcode level, etc.

[0050] In some embodiments, the plurality of process modules 150 may further include a flipping module 161, a third detection module 163, a second marking module 165, and a fourth detection module 167.

[0051] The flipping module 161 is located downstream of the second detection module 159, the third detection module 163 is located downstream of the flipping module 161, the second marking module 165 is located downstream of the flipping module 161, and the fourth detection module 167 is located downstream of the second marking module 165. The flipping module 161 is used to flip the material 30, the second marking module 165 is used to form a second mark on the upper side of the material 30, and the fourth detection module 167 is used to detect the second mark. Thus, the moving stage 133 can transfer the material 30 after single-sided processing to the flipping mechanism. The flipping mechanism can flip the material 30. For example, the flipping mechanism can flip the material 30 180° so that the side of the material 30 with the first mark is facing down and the side of the material 30 facing away from the first mark is facing up. The moving platform 133 then sequentially transfers the material 30 to the third detection module 163, the second marking module 165, and the fourth detection module 167, where the side of the material 30 facing away from the first mark is marked and inspected again. During the entire cycle of the moving platform 133 transferring the material 30, the material 30 only needs to be flipped once by the flipping mechanism to mark both the top and bottom sides of the material 30. This eliminates the need for multiple handling of the material 30, which helps improve the marking accuracy and increases the material 30 conveying efficiency and production capacity.

[0052] As an example, the flipping mechanism may include a flipping component and a material transfer component. The suspended surface 1310 may also have a first station and a second station. The flipping component is connected to the frame 110 and is located at the first station. The material transfer component is connected to the frame 110 and is movable between the first station and the second station. When the moving platform 133 moves to the first station, the flipping component grabs the material 30 on the moving platform 133 and flips the material 30, for example, flipping the material 30 180°. At this time, the unloaded moving platform 133 moves to the second station. The material transfer component moves to the first station, grabs the material 30 on the flipping component, moves it to the second station, and places the material 30 on the unloaded moving platform 133.

[0053] The second marking module 165 can be a laser engraving machine or other marking devices. The detection method of the third detection module 163 can refer to the detection method of the first detection module 155 in the above embodiment, and the detection method of the fourth detection module 167 can refer to the detection method of the second detection module 159 in the above embodiment, and will not be described again.

[0054] In some embodiments, the plurality of process modules 150 may further include a second vacuum pumping module and a second vacuum breaking module.

[0055] The second vacuum breaking module can be connected to the frame 110 and located between the second detection module 159 and the flipping module 161. The second vacuum breaking module is used to break the vacuum in the vacuum adsorption carrier 1350 so that the flipping module 161 can flip the material 30. The second vacuum extraction module can be located between the flipping module 161 and the fourth detection module 167. The second vacuum extraction module is used to extract the gas in the vacuum adsorption carrier 1350 so that the vacuum adsorption carrier 1350 generates negative pressure to adsorb and position the material 30, so as to avoid the material 30 from shifting or falling during the movement of the moving platform 133, thereby improving the stability of the material 30 conveying and helping to ensure the accuracy of subsequent processing.

[0056] The structure and vacuuming method of the second vacuuming module can be the same as those of the first vacuuming module 151 in the above embodiment, and the vacuum breaking method of the second vacuum breaking module can be the same as those of the first vacuum breaking module 153 in the above embodiment, and will not be described again.

[0057] In some embodiments, the number of first marking modules 157 can be multiple. Thus, by increasing the number of first marking modules 157, each first marking module 157 can correspond to one moving stage 133, allowing multiple first marking modules 157 to mark multiple materials 30, thereby improving production capacity. Similarly, the number of second marking modules 165 can be multiple. Thus, by increasing the number of second marking modules 165, each second marking module 165 can correspond to one moving stage 133, allowing multiple second marking modules 165 to mark multiple materials 30, further improving production capacity.

[0058] The number of first marking modules 157 is A, and the number of second marking modules 165 is B, satisfying that A > B. Since the first marking modules 157 are located upstream of the magnetic levitation processing equipment 10, by setting more first marking modules 157, more materials 30 can be processed in multiple first marking modules 157, thereby providing more materials 30 processed by the first marking modules 157 to the downstream process modules 150. This helps to avoid the situation where the subsequent process modules 150 have no materials 30 to process, making the overall production process more compact and further improving the production capacity.

[0059] As an example, the number of first marking modules 157 can be three, four, five, six, seven, eight, nine or other numbers, and the number of second marking modules 165 can be two, three, four, five, six, seven, eight or other numbers.

[0060] In some embodiments, the first detection module 155 and the plurality of first marking modules 157 are all located on one side of the stator platform 131 along the second horizontal direction Y, and the second detection module 159, the flipping module 161, the third detection module 163, the plurality of second marking modules 165 and the fourth detection module 167 are all located on the other side of the stator platform 131 along the second horizontal direction Y. This allows for better utilization of the space on the opposite sides of the stator platform 131 in the second horizontal direction Y, enabling a more reasonable layout of each process module 150. This helps to shorten the length of the magnetic levitation processing equipment 10 in the first horizontal direction X and reduces the floor space occupied by the magnetic levitation processing equipment 10 in the first horizontal direction X.

[0061] The first detection module 155 and multiple first marking modules 157 are sequentially distributed along the first horizontal direction X, resulting in a more regular distribution of the first detection module 155 and multiple first marking modules 157. Furthermore, it eliminates the need to set the edge of the suspended surface 1310 in a complex shape along the second horizontal direction Y, reducing the manufacturing difficulty of the stator platform 131. Similarly, the second detection module 159, the flipping module 161, the third detection module 163, multiple second marking modules 165, and the fourth detection module 167 are sequentially distributed along the first horizontal direction X, resulting in a more regular distribution of the second detection module 159, the flipping module 161, the third detection module 163, multiple second marking modules 165, and the fourth detection module 167. This also eliminates the need to set the other edge of the suspended surface 1310 in a complex shape along the second horizontal direction Y, further reducing the manufacturing difficulty of the stator platform 131.

[0062] In some embodiments, the number of moving platforms 133 is C, and the number of process modules 150 is D, satisfying C≥D. When C=D, each process module 150 can correspond to one moving platform 133 when each moving platform 133 is transferring material 30, which helps to avoid the situation where the process module 150 waits for the moving platform 133 for a long time. When C>D, it helps to further reduce the waiting time of the process module 150 and further improve the production capacity of the magnetic levitation processing equipment 10.

[0063] As an example, the number of moving stage 133 can be 19, and the number of process modules 150 can be 18, 17, 16, 15, 14 or other numbers.

[0064] As another example, the number of moving stage 133 can be 24, and the number of process modules 150 can be 23, 22, 21, 20, 19 or other numbers.

[0065] Please see Figure 1 , Figure 2 and Figure 5In some embodiments, the magnetic levitation processing equipment 10 may also include a loading and unloading device 170 and a transferring device 190. The loading and unloading device 170 may include a loading conveying mechanism 171 and a unloading conveying mechanism 173.

[0066] Along the first horizontal direction X, the material transfer device 190 is located between the loading / unloading device 170 and the stator platform 131. The material transfer device 190 can transfer materials 30 between the loading / unloading device 170 and the moving platform 133. For example, the material transfer device 190 can transfer the material 30 to be processed to the moving platform 133, and the material transfer device 190 can transfer the processed material 30 to the loading / unloading device 170, thus eliminating the need for manual loading / unloading on the moving platform 133, which helps to further improve production capacity.

[0067] In some embodiments, the loading and unloading device 170 may include a loading conveying mechanism 171 and a unloading conveying mechanism 173, the transferring device 190 may include a first transferring mechanism 191 and a second transferring mechanism 193, and the suspended surface 1310 has a loading station 1312 and a unloading station 1314.

[0068] The loading station 1312 and the unloading station 1314 are both located on the side of the suspension surface 1310 along the first horizontal direction X, close to the transfer device 190. The loading conveyor mechanism 171 and the unloading conveyor mechanism 173 are both connected to the frame 110, and the first transfer mechanism 191 and the second transfer mechanism 193 are both connected to the frame 110. The first material transfer mechanism 191 can transfer material 30 between the loading station 1312 and the loading conveyor mechanism 171, and the second material transfer mechanism 193 can transfer material 30 between the unloading station 1314 and the unloading conveyor mechanism 173. Thus, the loading conveyor mechanism 171 can transport the material 30 to be processed, and the first material transfer mechanism 191 can transfer the material 30 to be processed onto the moving platform 133 of the loading station 1312 to realize the loading of the moving platform 133; while the unloading conveyor mechanism 173 can transport the processed material 30, and the first material transfer mechanism 191 can transfer the material 30 carried on the moving platform 133 of the unloading station 1314 to the unloading conveyor mechanism 173 to realize the unloading of the moving platform 133. Thus, the material 30 can be transferred between the loading / unloading module and the magnetic levitation conveyor device 130 through the first material transfer mechanism 191 and the second material transfer mechanism 193 without manual operation, which helps to further improve production capacity.

[0069] Furthermore, since the loading and unloading device 170 integrates the loading conveyor mechanism 171 and the unloading conveyor mechanism 173, and both the loading conveyor mechanism 171 and the unloading conveyor mechanism 173 are arranged on one side of the stator platform 131 along the first horizontal direction X, the loading conveyor mechanism 171 and the unloading conveyor mechanism 173 are closer together, so that loading and unloading can be realized on the same side of the stator platform 131 along the first horizontal direction X. This helps to avoid the situation where the overall production line of the magnetic levitation processing equipment 10 is too long due to the long distance between loading and unloading, and helps to reduce the footprint of the magnetic levitation processing equipment 10. In addition, since the loading conveyor mechanism 171 and the unloading conveyor mechanism 173 are both arranged on one side of the stator platform 131 along the first horizontal direction X, the first transfer mechanism 191 and the second transfer mechanism 193 can be concentrated between the loading and unloading device 170 and the stator platform 131, which helps to make the overall layout of the magnetic levitation processing equipment 10 more compact.

[0070] Both the first material transfer mechanism 191 and the second material transfer mechanism 193 can be robotic arms or other mechanisms capable of handling materials 30. Both the loading conveyor mechanism 171 and the unloading conveyor mechanism 173 can be belt conveyors, roller conveyors, or other mechanisms capable of conveying materials 30. The conveying directions of the loading conveyor mechanism 171 and the unloading conveyor mechanism 173 can be parallel or intersecting, depending on the actual situation. For example, the loading conveyor mechanism 171 and the unloading conveyor mechanism 173 can convey materials 30 along the first horizontal direction X, and their conveying directions are opposite.

[0071] In some embodiments, the transfer device 190 may further include a first temporary storage stage.

[0072] The first temporary storage platform may have one or more first storage positions, each of which can hold one material 30. One of the first transfer mechanisms 191 can transfer the material 30 on the feeding conveyor 171 to the first storage position, and the other first transfer mechanism 191 can transfer the material 30 in the first storage position to the moving platform 133, which helps to improve the feeding efficiency.

[0073] As an example, the material transfer device 190 may further include a first detector connected to the frame 110, with one first detector corresponding to each first storage position. The first detector is used to detect the placement position of the material 30 at the first storage position. The first temporary storage platform may be an XYR alignment platform. When the first detector detects a deviation between the placement position of the material 30 at the first storage position and a preset position, the XYR alignment platform can correct the placement position of the material 30 at the first storage position. The first detector may be a CCD camera or other vision inspection device.

[0074] In some embodiments, the transfer device 190 may further include a second temporary storage stage.

[0075] The second temporary storage platform may have one or more second storage positions, each of which can hold one material 30. One of the second transfer mechanisms 193 can transfer the material 30 carried by the moving platform 133 to the second storage position, and the other second transfer mechanism 193 can transfer the material 30 carried by the second storage position to the unloading conveyor mechanism 173, which helps to improve the unloading efficiency.

[0076] As an example, the material transfer device 190 may also include a second detector connected to the frame 110, with one second detector corresponding to each second storage position. The second detector is used to detect the placement position of the material 30 in the second storage position. The second temporary storage platform may be an XYR alignment platform. When the second detector detects a deviation between the placement position of the material 30 in the second storage position and a preset position, the XYR alignment platform can correct the placement position of the material 30 in the second storage position. The second detector may be a CCD camera or other vision inspection device.

[0077] In some embodiments, the loading and unloading device 170 may further include a defective product conveying mechanism 175.

[0078] Among them, the defective product conveying mechanism 175 is connected to the frame 110, and the second material transfer mechanism 193 can also transfer the material 30 of the unloading station 1314 to the defective product conveying mechanism 175, thereby enabling the separate conveying of good material 30 and defective material 30, eliminating the need for subsequent manual selection of good material 30 and defective material 30, thus simplifying the production process; and since the defective product conveying mechanism 175 is also integrated into the loading and unloading device 170, and the defective product conveying mechanism 175 is also arranged on one side of the stator platform 131 along the first horizontal direction X, the defective material 30 can be concentrated in the defective product conveying mechanism 175 for unloading, eliminating the need to set up a defective product conveying mechanism 175 in each process module 150, which helps to further simplify the production line layout of the magnetic levitation processing equipment 10.

[0079] As an example, as in the example above, the second transfer mechanism 193 can transfer the material 30 carried by the marked target platform to the defective product conveying mechanism 175, while the material 30 carried by the unmarked moving platform 133 is the good product material 30, and the second transfer mechanism 193 can transfer the material 30 carried by the unmarked moving platform 133 to the unloading conveying mechanism 173. Understandably, when the second transfer mechanism 193 removes the material 30 carried by the target platform, the controller can clear the mark on the target platform, helping to avoid the inability to distinguish between good and defective material 30.

[0080] The conveying directions of the defective product conveying mechanism 175, the loading conveying mechanism 171, and the unloading conveying mechanism 173 can be parallel, intersect each other, or two of the three can be parallel. For example, the defective product conveying mechanism 175 can convey along the first horizontal direction X, and the conveying direction of the defective product conveying mechanism 175 is the same as the conveying direction of the unloading conveying mechanism 173.

[0081] In some embodiments, along the second horizontal direction Y, the defective product conveying mechanism 175 may be located on the side of the unloading conveying mechanism 173 away from the loading conveying mechanism 171.

[0082] In some embodiments, the loading and unloading device 170 may further include a pallet conveying mechanism 177 and a third material transfer mechanism 179.

[0083] The pallet conveying mechanism 177 and the third transfer mechanism 179 are both connected to the frame 110. The pallet conveying mechanism 177 is used to convey empty pallets, and the loading conveying mechanism 171 is used to convey pallets containing material 30. The third transfer mechanism 179 can transfer empty pallets on the loading conveying mechanism 171 or the pallet conveying mechanism 177 to the unloading conveying mechanism 173 or the defective product conveying mechanism 175. This allows the pallet conveying mechanism 177 to replenish empty pallets, which helps to avoid the situation where the material 30 in the pallet on the loading conveying mechanism 171 has not been completely transported by the first transfer mechanism 191, and there is no pallet on the unloading conveying mechanism 173 or the defective product conveying mechanism 175 to hold the material 30 when the second transfer mechanism 193 is unloading.

[0084] The conveying directions of the pallet conveyor 177, the defective product conveyor 175, the loading conveyor 171, and the unloading conveyor 173 can be parallel, intersect in pairs, or have three of them parallel. For example, the pallet conveyor 177 can convey along the first horizontal direction X, and the conveying direction of the pallet conveyor 177 is the same as the conveying direction of the loading conveyor 171.

[0085] In some embodiments, along the second horizontal direction Y, the pallet conveying mechanism 177 is disposed between the loading conveying mechanism 171 and the unloading conveying mechanism 173.

[0086] In the magnetic levitation processing equipment 10 provided in this application embodiment, the upper side of the stator platform 131 has a suspension surface 1310. Multiple process modules 150 are connected to the frame 110 and distributed along the periphery of the suspension surface 1310. Under the action of the electromagnetic field generated by the stator platform 131, each movable carrier 133 can levitate above the suspension surface 1310 and can reciprocate along the vertical direction Z, along the first horizontal direction X, and along the second horizontal direction Y. The movable carrier 133 is used to carry the material 30. Driven by the electromagnetic field, the movable carrier 133 can sequentially transfer the material 30 to each process module 150, thereby enabling the magnetic levitation conveying device 130 to function. It can connect to various process modules 150. The moving platform 133 can move flexibly in multiple directions above the suspension surface 1310. The moving platform 133 can directly transfer the material 30 to each process module 150 for processing. There is no need to set up a conveyor belt for transporting the material 30 and a robot for handling the material 30 between two adjacent process modules 150. This helps to simplify the production line layout of the magnetic levitation processing equipment 10 and can also improve the material 30 conveying efficiency and capacity. Furthermore, since the material 30 is always positioned on the moving platform 133, there is no need to set up a robot to handle the material 30, which helps to improve the processing accuracy of the process module 150 in processing the material 30.

[0087] The embodiments of the present invention have been described in detail above with reference to the accompanying drawings. However, the present invention is not limited to the above embodiments, and various changes can be made within the scope of knowledge possessed by those skilled in the art without departing from the spirit of the present invention. Furthermore, the embodiments of the present invention and the features thereof can be combined with each other unless otherwise specified.
