Description

Technical Field

[0001] The utility model relates to the technical field of conveying equipment, and particularly relates to a magnetic drive conveying system. Background Art

[0002] In the related art, a conveying system includes a mover and a stator conveying line formed by splicing a plurality of stators. The coils in the stator conveying line are periodically electrified to generate a traveling magnetic field, which enables the mover to float on the stator conveying line without any supporting components and drives the mover to move along a preset planned route, thereby realizing the transportation of objects.

[0003] The stator conveying line may include multiple sub-line bodies, and among them, there are height differences in some sub-line bodies. Therefore, a lifting mechanism is provided in the conveying system to lift the mover on one of the sub-line bodies and transfer it to another sub-line body.

[0004] However, sometimes the running directions of the sub-line bodies on the opposite sides of the lifting mechanism are not the same. Therefore, the workpiece carried on the mover cannot meet the process requirements of this sub-line body after lifting, and the workpiece on the mover needs to be reversed before lifting to adapt to the process requirements of the sub-line body after lifting. However, the process of reversing the workpiece on the mover before lifting will reduce the conveying efficiency. Summary of the Utility Model

[0020] In one possible implementation, the transfer assembly includes a second driving source and a driving plate drivingly connected to the second driving source, and the second driving source drives the driving plate to move in a horizontal direction to drive the mover module to transfer from the lifting member to the second stator.

The terms used in the description of this specification are only for the purpose of describing specific embodiments and are not intended to limit the present utility model. The term "and / or" used herein includes any and all combinations of one or more of the related listed items.

[0042] Please refer to Figure 1 and Figure 2 , an embodiment of the present application provides a magnetic drive conveying system 1, including a mover module 10, a stator conveying line 20, and a lifting mechanism 50.

[0043] The mover module 10 serves as a load-bearing component for stably carrying and transporting products. The stator conveying line 20 includes at least two conveying lines at different horizontal levels. The conveying lines are magnetically coupled to the mover module 10 and are used to drive the mover module 10 to move. The lifting mechanism 50 is used to lift and transport the mover module 10 located on one of the conveying lines to another conveying line.

[0044] It can be understood that the transportation directions of multiple conveying lines may be the same or different. In the existing mover, the permanent magnets are arranged only in one direction. When the transportation directions of the two conveying lines on opposite sides of the lifting mechanism 50 are different, it is necessary to guide the mover to rotate to change the movement direction of the mover so that the mover can be magnetically coupled to the next sub-line body, and such an operation is rather troublesome.

[0045] The mover module 10 of the present application includes a mover base 110 and a permanent magnet assembly 120 disposed on the mover base 110. Please refer to Figures 5 to 6, the permanent magnet assembly 120 includes a first permanent magnet array 121 arranged along the first direction X-X and a second permanent magnet array 122 arranged along the second direction Y-Y, and the first direction X-X and the second direction Y-Y are arranged at an angle. Exemplarily, the first direction X-X and the second direction Y-Y are perpendicular to each other. With such an arrangement, when the transport directions of two conveyor lines on opposite sides of the lifting mechanism 50 are different, for example, when the transport directions of the two conveyor lines are perpendicular to each other, among them, the first permanent magnet array 121 can be magnetically coupled with one of the conveyor lines, and when the lifting mechanism 50 lifts and transfers the mover module 10 to the other conveyor line, the second permanent magnet array 122 of the mover module 10 can be magnetically coupled with the other conveyor line. Thus, the lifting mechanism 50 only needs to lift the mover module 10 from one conveyor line to the other conveyor line, and the mover module 10 can be transported. That is, whether the mover module 10 runs to the lifting mechanism 50 relying on the first permanent magnet array 121 or the mover module 10 runs to the lifting mechanism 50 relying on the second permanent magnet array 122, the lifting mechanism 50 can cooperate with the mover module 10 to run the mover module 10 to the other conveyor line.

[0046] Furthermore, by arranging the first permanent magnet array 121 and the second permanent magnet array 122 at an angle in the mover module 10, when the mover module 10 runs to the lifting mechanism 50 relying on the first permanent magnet array 121, the workpiece carried by the mover module 10 may have a first placement form (the placement form can be, for example, the placement direction, placement position, workpiece type, etc.). When the mover module 10 runs to the lifting mechanism 50 relying on the second permanent magnet array 122, the workpiece carried by the mover module 10 may have a second placement form. That is, the lifting mechanism 50 can cooperate with the mover module 10 carrying different workpiece forms to transport the mover module 10 to the corresponding conveyor line, thereby improving the transportation diversity; and since the first permanent magnet array 121 and the second permanent magnet array 122 of the mover module 10 can be flexibly magnetically coupled with different conveyor lines, without additionally setting an actuator to reverse the workpiece on the mover module 10, the workpiece placement form can be changed relying on the structural characteristics of the mover module 10 itself, and the change of the workpiece placement form before and after lifting can be completed, thereby improving the conversion efficiency.

[0047] The conveyor line includes a plurality of sub-line bodies spliced together and a commutation module 40. It can be understood that the extension directions of multiple sub-line bodies may be the same or different. When the transport directions of two adjacent sub-line bodies are different, the commutation module 40 connects the two sub-line bodies so that the mover module 10 can be commuted from one sub-line body to the other sub-line body.

[0048] Please refer to Figure 3, in some embodiments, the commutation module 40 has a commutation winding 410 and a stop structure 420. The commutation winding 410 can be selectively magnetically coupled to the first permanent magnet array 121 and the second permanent magnet array 122. Among them, the commutation winding 410 may include a coil substrate 411, and a first commutation winding 412 and a second commutation winding 413 disposed on the coil substrate 411. The first commutation winding 412 extends along the first direction X-X, and the second commutation winding 413 extends along the second direction Y-Y. The first commutation winding 412 is magnetically coupled to the first permanent magnet array 121 to drive the mover module 10 to move along the first direction X-X, and the second commutation winding 413 is magnetically coupled to the second permanent magnet array 122 to drive the mover module 10 to move along the second direction Y-Y. The related driving principle has been disclosed and will not be elaborated in this application.

[0049] Please refer to Figure 5 and Figure 6 , the mover base 110 is provided with a first limiting portion 112 extending along the first direction X-X and a second limiting portion 113 extending along the second direction Y-Y. Among them, the first limiting portion 112 and the second limiting portion 113 are in limiting cooperation with the stop structure 420 to improve the stability of the mover module 10 moving along the first direction X-X or the second direction Y-Y. The first limiting portion 112 and the second limiting portion 113 can provide a larger contact area, thereby enhancing the stability of the mover module 10 during limiting. In some embodiments, the first limiting portion 112 and the second limiting portion 113 can be directly integrated on the mover base 110, which can simplify the assembly process of the mover base 110.

[0050] Please refer to Figure 3 , the stop structure 420 includes a first limiting component 421 and a second limiting component 422. The first limiting component 421 and the second limiting component 422 are spaced apart and disposed on the peripheral side of the coil substrate 411. The first limiting component 421 and the first limiting portion 112 are used to limit the movement of the mover module 10 in the first direction X-X, and the second limiting component 422 is used to limit the movement of the mover module 10 in the second direction Y-Y. With such a setting, when the first limiting component 421 acts, the movement of the mover module 10 in the second direction Y-Y is restricted, so that it can only move in the first direction X-X. When the second limiting component 422 acts, the movement of the mover module 10 in the first direction X-X is restricted, so that it can only move in the second direction Y-Y, improving the stability of the mover module 10 moving along the first direction X-X or the second direction Y-Y.

[0051] Please continue to refer to Figure 6, in some embodiments, the first limiting component 421 includes a first power source 4211 and a first baffle 4212 drivingly connected to the first power source 4211. The second limiting component 422 includes a second power source 4221 and a second baffle 4222 drivingly connected to the second power source 4221. Among them, there are two first baffles 4212, which are spaced apart in the second direction Y-Y and extend in the first direction X-X. There are two second baffles 4222, which are spaced apart in the first direction X-X and extend in the second direction Y-Y. In some embodiments, the first power source 4211 drives the first baffle 4212 to perform lifting operations in the height direction, and the second power source 4221 drives the second baffle 4222 to perform lifting operations in the height direction. In this way, when the first baffle 4212 or the second baffle 4222 rises, the mover module 10 can be restricted.

[0052] In some structural forms, the first baffle 4212 and the second baffle 4222 can be respectively located on the four peripheral sides of the coil substrate 411. Among them, the first power source 4211 and the second power source 4221 can be fixed on the four peripheral sides of the coil substrate 411, while the first baffle 4212 is fixed on the drive shaft of the first power source 4211, and the second baffle 4222 is fixed on the drive shaft of the second power source 4221. The first power source 4211 and the second power source 4221 can be cylinders, lead screws, linear motors, etc., and this application does not make limitations in this regard.

[0053] In some embodiments, the mover base 110 includes a base portion 111, a first limiting portion 112 and a second limiting portion 113 are connected to the bottom of the base portion 111, and the first limiting portion 112 and the second limiting portion 113 alternately surround the four peripheral sides of the guiding component 130. In this example, the base portion 111, the first limiting portion 112 and the second limiting portion 113 can be an integral structure. In this way, the installation operation of the mover base 110 can be simplified, and the stability of the first limiting portion 112 and the second limiting portion 113 can be improved. Among them, the base portion 111 is used to carry products and install the permanent magnet component 120. The specific structure of the base portion 111 in the embodiments of the present application is not limited. For example, the base portion 111 can be a cuboid structure or a cylindrical structure. In addition, the materials used for the mover base 110 in the embodiments of the present application are not specifically limited. For example, the mover base 110 can use aluminum materials, stainless steel metal materials or carbon fiber composite materials, etc. Exemplarily, when the mover base 110 uses aluminum materials, the aluminum materials can be attracted by the magnetic field generated by the stator coil on the stator conveyor line 20 after the stator conveyor line 20 is energized, so that the mover module 10 can be stably conveyed by the stator conveyor line 20.

[0054] Please refer to Figure 4, in some embodiments, the magnetic drive conveying system 1 includes a first sub-line body 210a, a second sub-line body 210b, a third sub-line body 210c, and a fourth sub-line body 210d. Among them, the first sub-line body 210a and the second sub-line body 210b extend at intervals in the same transportation direction, and the third sub-line body 210c and the fourth sub-line body 210d extend side by side in another transportation direction. Among them, the commutation module 40 is connected between the first sub-line body 210a, the second sub-line body 210b, and the third sub-line body 210c, and the commutation module 40 is connected between the third sub-line body 210c and the fourth sub-line body 210d. The third sub-line body 210c and the fourth sub-line body 210d are both connected with a lifting mechanism 50. The placement form of the workpiece carried by the mover module 10 in the third sub-line body 210c is different from the placement form of the workpiece carried by the mover module 10 in the fourth sub-line body 210d. The mover module 10 is driven by the commutation module 40 to rotate. By switching the permanent magnet array coupled between the mover module 10 and the sub-line body, the movement direction of the mover module 10 is changed, and thus the placement form of the workpiece is changed, so that the lifting mechanism 50 can convey the mover modules 10 in different placement forms to the next sub-line body. That is to say, in the magnetic drive conveying system 1 in the embodiments of the present application, the movement direction of the mover module 10 is changed by setting the commutation module 40, thereby changing the placement form of the workpiece, avoiding the use of an external actuator to process the workpiece, and thus improving the conveying efficiency.

[0055] Regarding how the lifting mechanism 50 lifts and transfers the mover module 10 located on one of the conveying lines to another conveying line, the present application will introduce this in detail below.

[0056] The conveying line includes a feeding conveying line 20a and a discharging conveying line 20b. The feeding conveying line 20a includes a first stator 20a1, and the discharging conveying line 20b includes a second stator 20b1. Both the first stator 20a1 and the second stator 20b1 can be magnetically coupled with the mover module 10. The mover module 10 can move relative to the first stator 20a1 in the first direction X-X and be positioned at the first stator 20a1. The lifting mechanism 50 includes a lifting drive assembly 510, a plurality of lifting members 520, and a transfer assembly 530. The lifting member 520 can support the mover module 10 positioned at the first stator 20a1, and the lifting drive assembly 510 can drive the lifting member 520 to lift in the height direction. Among them, the lifting member 520 has a lifting initial position and a lifting target position. The first stator 20a1 is arranged at the lifting initial position, and the second stator 20b1 is arranged at the lifting target position. There is a height difference between the lifting initial position and the lifting target position; the transfer assembly 530 transfers the mover module 10 located on the lifting member 520 to the second stator 20b1.

[0057] Specifically, the mover module 10 moves from the feeding conveyor line 20a to the first stator 20a1. After the mover module 10 moves into place, the first stator 20a1 is powered off, and the mover module 10 stops moving and is positioned at the first stator 20a1. At this time, the lifting member 520 located at the initial lifting position is at the lower end of the mover module 10. The lifting drive assembly 510 drives the lifting member 520 to rise to the target lifting position. When the lifting member 520 supports the mover module 10 and rises to the preset target lifting position, the mover module 10 is on one side of the second stator 20b1. The transfer assembly 530 transports the mover module 10 on the lifting member 520 to the second stator 20b1, and the mover module 10 is magnetically coupled to the second stator 20b1 and can operate on the discharging conveyor line 20b.

[0058] Multiple discharging conveyor lines 20b can be provided, and the heights of each discharging conveyor line 20b are different. Correspondingly, the lifting member 520 can have multiple target lifting positions, and each target lifting position matches one discharging conveyor line 20b. That is, there is a height difference between the target lifting positions, and each target lifting position corresponds to a lifting height. Among them, the initial lifting position is directly below all the target lifting positions, and the lifting member 520 can lift and transfer the mover module 10 on the feeding conveyor line 20a to different discharging conveyor lines 20b according to the preset settings.

[0059] There can be multiple groups of the lifting members 520, and each group includes two lifting members 520. The lifting drive assembly 510 drives the two lifting members 520 in the same group to rise synchronously. For the two lifting members 520 in the same group, in the second direction Y - Y, the two lifting members 520 are spaced apart, and the two lifting members 520 support the first limiting portion 112 or the second limiting portion 113 of the mover module 10. The two lifting members 520 can keep the mover module 10 horizontal. When the lifting drive assembly 510 works, the two lifting members 520 drive the mover module 10 to rise. The first limiting portion 112 and the second limiting portion 113 of the present application can be used not only for commutation but also for abutting against the lifting member 520 during lifting. The first limiting portion 112 and the second limiting portion 113 not only abut against the lifting member 520 during lifting but also can be used for commutation. In this way, multiple functions are integrated into a single component, avoiding the use of multiple dedicated components, thereby simplifying the structural design of the mover module 10, reducing redundant design, and saving material costs and processing costs. In addition, the volume of the overall equipment can be made smaller, improving the compactness and adaptability of the equipment.

[0060] In some embodiments, the lifting drive assembly 510 includes a power source and a transmission mechanism. The power source can output power, and the power is transmitted to the lifting member 520 through the transmission mechanism, so that the lifting member 520 can be lifted vertically. The power source can be a motor. The transmission mechanism can include a synchronous belt transmission mechanism, a chain transmission mechanism, or a crawler transmission mechanism, so that the lifting member 520 has a large lifting stroke. The lifting member 520 is fixedly connected to the synchronous belt, chain, or crawler. The lifting mechanism 50 using the synchronous belt transmission mechanism is used as an example for description.

[0061] See also Figure 2 The lifting drive assembly 510 includes a first motor 511, a reducer 512, a first transmission shaft 513, a second transmission shaft 514, a third transmission shaft 515, a fourth transmission shaft 516 and a fifth transmission shaft 517. The first motor 511 has a motor shaft extending in the height direction, the reducer 512 is fixedly connected to the motor shaft, and is provided with two drive shafts, which are respectively extended in the first direction XX and the second direction YY, wherein the first transmission shaft 513 is transmission-connected to one of the drive shafts and is extended in the first direction XX, and the second transmission shaft 514 is transmission-connected to the other drive shaft and is extended in the second direction YY. The third transmission shaft 515 is arranged on the frame 60 and extends in the first direction XX. The third transmission shaft 515 and the first transmission shaft 513 are spaced apart in the height direction. The first transmission shaft 513 and the third transmission shaft 515 are both provided with a first synchronous wheel 5111, and the first synchronous wheel 5111 is provided with a first synchronous belt 5112. The lifting member 520 is fixedly connected to the first synchronous belt 5112. When the reducer 512 drives the first transmission shaft 513 to move, the first transmission shaft 513, the third transmission shaft 515, the first synchronous wheel 5111 and the first synchronous belt 5112 work together to drive the lifting member 520 to rise and fall in the height direction.

[0062] One end of the second transmission shaft 514 away from the speed reducer 512 is fixed with a first bevel gear. The fourth transmission shaft 516 is arranged to extend in the first direction X-X, and one end thereof is fixed with a second bevel gear that mates with the first bevel gear. The fifth transmission shaft 517 is arranged on the frame 60 and extends in the first direction X-X. The fifth transmission shaft 517 and the fourth transmission shaft 516 are arranged at intervals in the height direction. Both the fifth transmission shaft 517 and the fourth transmission shaft 516 are sleeved with second synchronous pulleys 5113, and a second synchronous belt 5114 is sleeved on the second synchronous pulleys 5113. The lifting member 520 is fixedly connected to the second synchronous belt 5114. When the speed reducer 512 drives the second transmission shaft 514 to move, under the cooperation of the first bevel gear and the second bevel gear, the fourth transmission shaft 516 is driven to rotate, and the fourth transmission shaft 516, the fifth transmission shaft 517, the second synchronous pulleys 5113 and the second synchronous belt 5114 act together to drive the lifting member 520 to move up and down in the height direction.

[0063] To facilitate the stable lifting of the mover module 10, two, three or more first synchronous belts 5112 and second synchronous belts 5114 can be provided, and the lifting member 520 is fixed to multiple synchronous belts, thereby improving the stability of lifting.

[0064] In some alternative structures, the transmission mechanism can include a chain transmission mechanism or a crawler transmission mechanism, that is, the first synchronous pulley 5111 and the second synchronous pulley 5113 are connected by a chain or a crawler, and the lifting member 520 is fixed to the chain or the crawler.

[0065] For a synchronous belt transmission mechanism, a chain transmission mechanism or a crawler transmission mechanism, multiple lifting members 520 can be fixed to the synchronous belt, the chain or the crawler, and the distance between two adjacent lifting members 520 can be equal to the first height difference. When the lifting member 520 stops rising, the lifting member 520 corresponds to the lifting target position or the lifting initial position.

[0066] In some embodiments, please refer to Figure 1 and Figure 2 , the lifting member 520 includes a substrate 521, a first roller 522 and a second roller 523. The substrate 521 is arranged to extend in the first direction X-X, and the substrate 521 is fixedly connected to the synchronous belt. The first roller 522 is rotatably installed on the substrate 521. A plurality of first rollers 522 are provided and arranged to extend in the first direction X-X. The first limiting portion 112 or the second limiting portion 113 of the mover module 10 is placed on the first roller 522. The second roller 523 is arranged on the substrate 521. The lifting mechanism 50 further includes a limiting guide rail 540 arranged on the frame 60. The limiting guide rail 540 extends in the vertical direction, and the second roller 523 can be slidably matched with the limiting guide rail 540, so as to ensure the horizontality and stability of the movement of the mover module 10, and reduce or avoid the adverse effect of unstable movement caused by the deformation of the synchronous belt.

[0067] Please refer to Figure 2 Figure 2 , the transfer assembly 530 includes a second driving source 531 and a driving plate 532 drivingly connected to the second driving source 531. The second driving source 531 drives the driving plate 532 to move in the horizontal direction, so as to drive the mover module 10 to be transferred from the lifting member 520 to the second stator 20b1. The second driving source 531 can be a motor, a lead screw, a cylinder, etc. The second driving source 531 drives the driving plate 532 to move in the horizontal direction, and the driving plate 532 drives the mover module 10 to move in the horizontal direction. Since the mover module 10 is supported by the first roller 522 on the lifting member 520, the mover module 10 can drive the first roller 522 to rotate while moving in the horizontal direction, improving the stability of the transfer of the mover module 10 and avoiding wear caused by friction between the mover module 10 and the lifting member 520.

[0068] In some embodiments, a first sensor is provided on the frame 60. The first sensor is disposed at the end point of the stroke of the first stator 20a1. The first sensor is used to sense the distance between the mover module 10 and the first sensor, so as to facilitate the controller to control the start and stop of the mover module 10 by controlling the first stator 20a1. A second sensor is also provided on the frame 60. There are multiple second sensors, and one second sensor can be provided at each lifting target position. The first sensor and the second sensor can be photoelectric sensors.
