[0002] The magnetic suspension circulation line adopts cable-free magnetic suspension control technology, making simple, flexible, high-speed and efficient multi-motor movement a reality. It can not only ensure high-precision control throughout the whole process, but also can be synchronously or asynchronously positioned and moved at high speed at any position. At the same time, the mover seat on the circulation line often needs to control multiple pairs of workpieces or material trays, such as clamping and positioning.

[0003] For example, Chinese patent publication number CN115159131A discloses a magnetic levitation conveying system and its carrier assembly, which relates to the field of magnetic levitation conveying, including a magnetic levitation track and a carrier assembly, wherein the magnetic levitation track has a suspension conveying channel, and the carrier assembly is arranged in the suspension conveying channel; the carrier assembly includes a first mover and a second mover arranged staggered in the vertical direction, the first mover is provided with a supporting member, the edge of the supporting member protrudes to the outside of the contour of the first mover, the second mover is provided with a pressing member, the edge of the pressing member protrudes to the outside of the contour of the second mover; the lower surface of the edge of the pressing member has a pressing part, and the upper surface of the supporting member has a supporting part for carrying materials. The materials are clamped and positioned by the pressing part and the supporting part, and the overall carrier assembly structure is simple and reliable, and can cooperate with the pre-positioning mechanism, which is conducive to the smooth transfer of materials and can transport materials quickly and accurately.

[0004] This application uses a support plate and a press plate to limit the raw materials during the conveying process, but the press plate will inevitably block the raw materials, thereby affecting the comprehensive processing of the raw materials by external equipment. Subsequently, the direction of the raw materials needs to be adjusted to expose the blocked area, and then the blocked area can be processed. The overall processing procedure is complicated and inefficient, and there are certain limitations in use.

[0005] Therefore, it is necessary to provide a dynamic magnetic circulation conveying device to solve the above technical problems. Summary of the invention

[0006] The object of the present invention is to provide a dynamic magnetic circulation conveying device to solve the problems raised in the above background technology.

[0007] In order to achieve the above purpose, a dynamic magnetic circulation conveying device is designed, which can limit the position of raw materials during transportation and automatically avoid them during processing, so that comprehensive processing can be achieved without adjusting the direction of the raw materials.

[0008] Based on the above ideas, the present invention provides the following technical solutions: a dynamic magnetic circulation conveying device, including a magnetic levitation circulation line, the magnetic levitation circulation line includes a track and a plurality of mover seats sliding along the track, a base is fixedly installed on one side of the mover seat, a rotating assembly corresponding to the position of the top surface of an adjacent mover seat is arranged on the base, and a plurality of wedge blocks corresponding to the position of the rotating assembly are fixedly installed on the track; when the mover seat moves along the track, the rotating assembly separates from the wedge block so that the rotating assembly partially overlaps with the top surface of the adjacent mover seat, and when the mover seat stops on the track, the rotating assembly contacts the wedge block so that the rotating assembly and the top surface of the adjacent mover seat are staggered.

[0009] As a further solution of the present invention: the distance between two adjacent wedge blocks is equal to the single movement stroke of the mover seat, so that the rotating component can contact several wedge blocks in sequence when moving with the mover seat.

[0011] As a further solution of the present invention: the first spring enables the push rod to have a tendency to slide downward based on the base. When the push rod is retracted into the base, the pressure plate can be rotated to a vertical state with the base through the pull rope and the circular shaft.

[0012] As a further solution of the present invention: the two sides of the wedge block are symmetrical and have a vertex position, the vertex position is located in the middle of the wedge block, and the vertex position corresponds to the stop position of the mover seat.

The number of the second springs is several and they are arranged in a circular array along the inner wall of the round head.

[0016] As a further solution of the present invention: the short rod and the round shaft are on the same horizontal line based on the base, and the length of the support rod is adapted to that of the pressure plate.

[0017] As a further solution of the present invention: the pull rope enables the circular shaft to drive the pressure plate to rotate at an angle greater than 90 degrees through the first fork, and enables the short rod to drive the support rod to rotate at an angle greater than 90 degrees through the second fork.

DETAILED DESCRIPTION

[0031] Embodiment 1:

[0032] See also Figures 1 to 4 The embodiment of the present invention provides a dynamic magnetic circulation conveying device, which is mainly convenient for processing raw materials on a mover seat 3. The device includes a magnetic suspension circulation line 1, which includes a track 2 and a plurality of mover seats 3 sliding along the track 2. The magnetic suspension circulation line 1 shown in this embodiment is partial, and in actual use it can be a linear reciprocating type or a circular reciprocating type. Among them, the magnetic suspension circulation line 1, the track 2 and the mover seat 3 are all existing mature technologies and will not be described in detail here.

[0033] Furthermore, a base 4 is fixedly installed on one side of the mover seat 3, and a rotating assembly 5 corresponding to the position of the top surface of the adjacent mover seat 3 is arranged on the base 4; at the same time, a wedge block 6 corresponding to the position of the rotating assembly 5 is fixedly installed on the track 2. When the mover seat 3 moves along the track 2, the rotating assembly 5 is separated from the wedge block 6 so that the rotating assembly 5 can be rotated to a state of partial overlap with the top surface of the adjacent mover seat 3; when the mover seat 3 moves to its position along the track 2 and stops, the rotating assembly 5 contacts the wedge block 6 so that the rotating assembly 5 is staggered from the top surface of the adjacent mover seat 3. In this way, the raw material on the mover seat 3 is limited when the mover seat 3 moves, and the raw material on the mover seat 3 is avoided when the mover seat 3 stops, which is convenient for nearby processing equipment or manipulators to approach for processing.

[0034] It should be noted that there are a plurality of wedge blocks 6, and the spacing between two adjacent wedge blocks 6 is equal to the single movement stroke of the movable seat 3, so that each time the movable seat 3 moves, the rotating assembly 5 can correspond to the next wedge block 6. Correspondingly, the movable seat 3 is provided with an avoidance opening 301 for the wedge block 6 to pass through.

[0035] It should also be noted that in this embodiment, the base 4 is placed on the left side of the mover seat 3, which corresponds to the sliding mode of the mover seat 3 from left to right. When the mover seat 3 is from right to left, the base 4 can be placed on the right side of the mover seat 3. The movement of the mover seat 3 is arranged in this way, so that even if the raw material is offset to the left or right on the mover seat 3, it can be blocked by the side wall of the base 4 to prevent it from falling. At the same time, the raw material in this embodiment can be a tray for holding workpieces, or it can be the workpiece itself, which can be freely selected according to actual needs and is not limited in this embodiment.

[0036] Reference Figure 3 to Figure 4 In this embodiment, preferably: the rotating assembly 5 includes a top rod 501 that is slidably matched with the base 4 and a round shaft 505 that is rotatably matched with the base 4. A first spring 504 is fixedly installed between the end of the top rod 501 and the base 4. The first spring 504 makes the top rod 501 have a tendency to slide downward relative to the base 4. A pull rope 503 that is fixedly connected to the top rod 501 is fixedly wound on the outer surface of the round shaft 505. A pressure plate 502 for realizing the position limitation of the raw material is also fixedly sleeved on the outer surface of the round shaft 505. The first spring 504 makes the top rod 501 in a state after being lowered in the initial state. At this time, the pull rope 503 is pulled so that the round shaft 505 drives the pressure plate 502 to be in a vertical state with the base 4.

[0037] In the above structure, the push rod 501 corresponds to the position of the wedge block 6, and can be lifted up by the wedge block 6 when it is close to the wedge block 6; when the push rod 501 is separated from the wedge block 6, the push rod 501 can automatically descend under the action of the first spring 504.

[0038] In order to realize the rotation of the pressing plate 502 driven by the circular shaft 505, a torsion spring (not shown in the figure) is sleeved on the outer surface of the circular shaft 505. The torsion spring makes the circular shaft 505 drive the pressing plate 502 to rotate to a vertical state. Figure 3 When the top rod 501 rises and the pull rope 503 is released, the torsion spring can drive the pressing plate 502 to rotate in the opposite direction through the circular shaft 505, and the pressing plate 502 and the base 4 are turned to a vertical state.

[0039] Reference Figure 2 and Figure 3 In this embodiment, it is preferred that: the two sides of the wedge block 6 are symmetrical and have a vertex position, the vertex position is located in the middle of the wedge block 6, and the vertex position corresponds to the stop position of the mover seat 3; when the push rod 501 moves along the wedge block 6, the push rod 501 has a movement process of first rising and then falling.

[0040] In this embodiment, the wedge block 6 is an arc-shaped protrusion. In actual use, the wedge block 6 can also be replaced with a triangle or an isosceles trapezoid, as long as the push rod 501 has a process of first rising and then falling, and does not affect the positioning of the raw material.

[0041] When in use, the raw material is placed on the mover seat 3 and fits with the side wall of the base 4 corresponding to the mover seat 3. At this time, the top rod 501 corresponds to the vertex position of the wedge block 6. The top rod 501 is in an ascending state relative to the base 4 and the first spring 504 is squeezed, and the pull rope 503 is released so that the round shaft 505 can drive the pressing plate 502 to rotate to a vertical state with the base 4. Then the magnetic suspension circulation line 1 drives the mover seat 3 and the raw material to move along the track 2, and the top rod 501 moves along the wedge block 6 and begins to descend under the action of the first spring 504 until it is completely separated from the wedge block 6. At this time, the pull rope 503 is stretched so that the round shaft 505 can drive the pressing plate 502 to rotate to a vertical state with the base 4, and the bottom surface of the pressing plate 502 fits with the top surface of the raw material.

[0042] It should be noted that in the above initial state, not all the mover seats 3 are loading materials. Usually, one mover seat 3 is loading materials and another mover seat 3 is unloading materials, while the remaining mover seats 3 are in the workpiece processing state.

[0043] In summary, through the cooperation of the pressure plate 502, the top rod 501, the pull rope 503 and the wedge block 6, the pressure plate 502 can be turned horizontally to limit the raw material to prevent the raw material from falling from the mover seat 3, and can also be turned vertically to stagger with the raw material so that the top surface of the raw material can be fully exposed, which is convenient for external equipment to carry out comprehensive processing without interference with the pressure plate 502. The processing process can be simplified and the work efficiency can be improved without adjusting the direction of the raw material. The overall structure is simple, and the base 4 can be used for the placement of the top rod 501 and the pressure plate 502 and other structures, and can also be used for the initial positioning of the raw material in the initial state, and can also provide support for the raw material when the mover seat 3 moves, which is more practical.

[0044] Embodiment 2:

[0045] See also Figures 1 to 8 On the basis of the first embodiment, in order to improve the overall applicability, the pressing plate 502 and the base 4 are improved: the end of the pull rope 503 away from the top rod 501 has a first fork 5031 and a second fork 5032, the first fork 5031 is fixedly wound outside the round shaft 505, and the side wall of the base 4 away from the pressing plate 502 is provided with a limiter assembly 7 fixedly connected to the second fork 5032, and the limiter assembly 7 and the end of the pressing plate 502 are both provided with a buffer assembly 8. The limiter assembly 7 and the pressing plate 502 are rotated in the opposite direction through the pull rope 503, and the buffer assembly 8 is directly in contact with the raw material.

[0046] In this embodiment, the pull rope 503 makes the circular shaft 505 drive the pressing plate 502 to an angle greater than 90 degrees. Of course, the pressing plate 502 can still be rotated to a vertical state with the base 4, and the pressing plate 502 can be further deflected toward the top surface of the mover seat 3 on the basis of being rotated to a vertical state with the base 4. When the pull rope 503 drives the pressing plate 502 to rotate through the circular shaft 505, it can also drive the limit assembly 7 to rotate, and the limit assembly 7 and the pressing plate 502 rotate in opposite directions. When the pressing plate 502 and the limit assembly 7 rotate, both can drive the buffer assembly 8 to move. At the same time, the pull rope 503 drives the limit assembly 7 to rotate at an angle greater than 90 degrees, which is the same as the working process of the pressing plate 502.

[0047] Reference Figure 5 and Figure 7 In this embodiment, preferably, the limiting assembly 7 includes a short rod 701 rotatably mounted on the base 4, and a support rod 702 for accommodating the buffer assembly 8 is fixedly mounted inside the short rod 701. The second fork 5032 is fixedly wound on the outer surface of the short rod 701, and the winding direction of the second fork 5032 based on the short rod 701 is opposite to the winding direction of the first fork 5031 based on the round shaft 505, so that the pull rope 503 passes through the first fork 5031 and the second fork 5032 when moving, so that the rotation directions of the round shaft 505 and the short rod 701 are opposite.

[0048] Furthermore, the side wall of the base 4 may be provided with a groove for accommodating the short rod 701, the support rod 702 and the buffer assembly 8 on one side. The groove prevents the short rod 701, the support rod 702 and the buffer assembly 8 on one side from being exposed, thereby facilitating the placement of the raw material on the mover seat 3 and the fitting with the base 4 in the initial state.

[0049] Reference Figure 6 and Figure 7 In this embodiment, preferably: the buffer assembly 8 includes a U-shaped round head 801, the end of the pressing plate 502 and the end of the support rod 702 are elastically connected to the round head 801 through the second spring 802, the round head 801 has a certain length along the axial direction of the short rod 701, and the number of the second springs 802 on the round head 801 is several, and the several second springs 802 are arranged in a ring array based on the inside of the round head 801, so that different areas of the round head 801 can squeeze the second spring 802 when contacting the raw material. At the same time, a cushion layer can be added to the outer surface of the round head 801 to reduce damage to the raw material.

[0050] Furthermore, in order to allow the support rod 702 and the pressing plate 502 to rotate simultaneously so that the two round heads 801 can contact the raw material at the same time, Figure 8As shown, the position of the short rod 701 is improved: the short rod 701 and the round shaft 505 are on the same horizontal line based on the base 4, and the size of the support rod 702 is adapted to the size of the pressing plate 502, and then when the first fork 5031 drives the round shaft 505 to rotate and the second fork 5032 drives the short rod 701 to rotate, the two pressing heads can finally contact the raw material synchronously. The position adjustment design of the support rod 702 can also ensure the stable rotation of the support rod 702, and avoid interference with the rotation of the support rod 702 after the raw material is attached to the bottom plate.

[0051] It should be noted that the support rod 702 based on the short rod 701 with the buffer assembly 8 and the pressure plate 502 based on the round shaft 505 with the buffer assembly 8 are completely the same in structure, except for the placement position and movement direction.

[0052] When in use, the pressing plate 502, the top rod 501 and the wedge block 6 can drive the pressing plate 502 to switch back and forth between the vertical state and the upright state based on the base 4. The working process and effect of this part are the same as those in the first embodiment, and will not be repeated here. The difference is that when the top rod 501 shrinks into the base 4 under the action of the wedge block 6 to release the pull rope 503, the first fork 5031 and the second fork 5032 respectively rotate the round shaft 505 and the short rod 701, and finally the pressing plate 502 and the support rod 702 rotate in the opposite direction, the support rod 702 drives the round head 801 to press the raw material on the same side of the moving sub-seat 3, and the pressing plate 502 drives the round head 801 to press the raw material on the adjacent moving sub-seat 3; the two round heads 801 can synchronously contact the raw material on the moving sub-seat 3, and when contacting the raw material, the round head 801 squeezes the second spring 802.

[0053] In the first embodiment, the height of the raw material based on the movable seat 3 must be equal to the distance between the top surface of the movable seat 3 and the bottom surface of the pressing plate 502. If the height of the raw material is lower, the pressing plate 502 cannot contact the raw material and cannot play a limiting role. There are certain limitations in use.

[0054] Compared with the first embodiment, through the coordination of the support rod 702, the round head 801, the second spring 802 and the pressure plate 502, the vertical state of the pressure plate 502 is kept staggered, and the angle when the pressure plate 502 and the support rod 702 rotate toward the mover seat 3 can be greater than 90 degrees, so that it can be used for raw materials with lower heights, further expanding the applicability of the device; at the same time, the round head 801 cooperates with the second spring 802 to effectively reduce the damage to the raw material and ensure the processing yield rate. The overall solution is combined with the setting of the pressure plate 502 and the pull rope 503, and the round head 801 is formed on both sides of the raw material to further improve the limiting effect on the raw material, and the effect is better when it is applicable to the circular reciprocating magnetic suspension circulation line 1, avoiding the deviation and falling off of the raw material when the mover seat 3 passes through the bend, and the overall applicability is stronger.

[0055] Embodiment three:

[0056] See also Figures 1 to 10 On the basis of the second embodiment, in order to ensure the positioning of the raw material on the mover seat 3, the base 4 and the push rod 501 are improved: at this time, a transmission component 9 fixedly connected to the pressure plate 502 is arranged inside the base 4, and a moving component 10 for pushing the raw material is arranged between the push rod 501, the base 4 and the transmission component 9.

[0057] When the push rod 501 contacts the wedge block 6 and shrinks into the base 4, on the one hand, it drives the pull rope 503 to move, and on the other hand, the moving assembly 10 moves through the transmission assembly 9, pushing the raw material on the mover seat 3 to ensure that its position relative to the mover seat 3 is constant.

[0058] Reference Fig. 9 and Fig.10 In this embodiment, preferably, the transmission assembly 9 includes a first rack 902 fixedly connected to the top rod 501 and a second rack 903 slidably matched with the base 4, and the first rack 902 and the second rack 903 are jointly connected to each other by a gear 901 rotatably matched with the base 4. The first rack 902, the second rack 903 and the gear 901 are all arranged in the cavity where the top rod 501 is arranged, and also share a cavity with the first spring 504 and the pull rope 503, but are staggered from the first spring 504 and the pull rope 503.

[0059] Furthermore, the first rack 902 and the second rack 903 move in opposite directions through the gear 901, and a notch can be provided at the top of the top rod 501 to avoid the movement of the second rack 903. The second rack 903 is rotationally matched with the moving assembly 10, that is, when the second rack 903 moves, the moving assembly 10 is rotatable relative to the second rack 903.

[0060] Reference Fig. 9 and Fig.10 In this embodiment, preferably: the moving assembly 10 includes two connecting rods 1001 rotatably mounted on the second rack 903 and the top rod 501 respectively, and the ends of the two connecting rods 1001 are rotatably mounted with a rotating shaft 1002. The outer surface of the rotating shaft 1002 is movably sleeved with a base 1003, and the outer surface of the base 1003 is elastically connected with a sleeve 1004 that can contact the raw material through a third spring 1005. A telescopic rod 1006 is fixedly mounted between the sleeve 1004 and the base 4, and the telescopic rod 1006 allows the sleeve 1004 to reciprocate only in the horizontal direction.

[0061] In the above structure, the two connecting rods 1001 are hinged with the rotating shaft 1002, so that when the second rack 903 and the top rod 501 approach each other, the two connecting rods 1001 also approach each other. At this time, the rotating shaft 1002 can move away from the base 4 and drive the base 1003 and the sleeve 1004 to move synchronously under the action of the telescopic rod 1006.

[0062] A sliding groove is provided on the surface of the base 4 away from the top rod 501 for the sliding of the two connecting rods 1001 . The sliding groove is connected to the cavity where the top rod 501 is placed, but will not affect the placement of the second rack 903 and the gear 901 .

[0063] It should be noted that the height position of the rotating shaft 1002 based on the base 4 is adapted to the height position of the top surface of the movable seat 3, so that when the rotating shaft 1002 drives the base 1003 and the sleeve 1004 to translate, the sleeve 1004 can smoothly reach the top surface of the movable seat 3, and it can be in contact with the top surface of the movable seat 3, or it can be slightly higher than the top surface of the movable seat 3.

[0064] When in use, the pressure plate 502, the top rod 501 and the wedge block 6 and other structures can drive the pressure plate 502 to switch back and forth between the vertical state and the upright state based on the base 4. The support rod 702, the round head 801 and the pressure plate 502 and other structures make the angle of the pressure plate 502 and the support rod 702 when they rotate toward the mover seat 3 is greater than 90 degrees, which can be suitable for use with raw materials of lower height. The working process and effect of this part are the same as those in Example 2 and will not be repeated here. The difference is that: when the top rod 501 shrinks into the base 4 under the action of the wedge block 6, on the one hand, the pull rope 503 is released, and on the other hand, the first rack 902 is driven to rise and the second rack 903 is driven to descend through the gear 901, and on the other hand, the lower connecting rod 1001 of the rotation cooperation is driven to rise, and when the second rack 903 descends, the upper connecting rod 1001 of the rotation cooperation can be driven to descend; under the action of the telescopic rod 1006, the rotating shaft 1002 can drive the base 1003 and the sleeve 1004 to approach the raw material on the top surface of the adjacent movable sub-seat 3. After contacting the raw material, the sleeve 1004 can move toward the base 1003 and squeeze the third spring 1005, and finally the raw material is limited between the sleeve 1004 and the adjacent base 4.

[0065] In the second embodiment, the two round heads 801 can be used to effectively limit the raw material in the up and down directions. However, when the mover seat 3 moves rapidly along the track 2, the raw material may be offset to the left and right directions based on the mover seat 3, resulting in errors in the subsequent processing of external equipment, which may cause damage to the raw material and has certain limitations in use.

[0066] Compared with the second embodiment, through the coordination of the structures such as the top rod 501, the connecting rod 1001, the sleeve 1004 and the base 1003, when the pressing plate 502 and the supporting rod 702 release the limitation of the raw material in the vertical direction, the sleeve 1004 can move horizontally to push the raw material so that it is located between the sleeve 1004 and the base 4, thereby realizing effective limitation of the raw material in the vertical direction and the left and right direction, avoiding errors in the processing after the subsequent external equipment is lowered, thereby avoiding damage to the raw material and ensuring the yield rate. The overall solution is combined with the movement of the top rod 501, which is conducive to the stable processing of the raw material, and will not affect the transportation of the raw material by the magnetic suspension circulation line 1. The coordination setting with the round heads 801 on both sides makes the overall limitation effect better and meets more needs in actual use.
