When the combination of technical solutions is contradictory or cannot be implemented, it should be considered that such combination of technical solutions does not exist and is not within the scope of protection claimed by this application.

[0029] like Figure 1 As shown, the first aspect of this application provides a conveying system 100, which includes a stator module 110 and a mover module 120.

[0030] The stator module 110 includes a base 111 and a stator body 112 disposed on the base 111. The base 111 supports the stator body 112, the mover module 120, and the workpiece to be transported. The connection between the stator body 112 and the base 111 can be by snap-fit, screw connection, etc. The base 111 can be installed on an installation platform or the ground to reliably support the mover module 120, making the transport of the mover module 120 more stable. Typically, the mover module 120 is positioned above the base 111.

[0031] The mover module 120 includes a support member 121 and a mover body 122 connected to the support member 121. The support member 121 is used to support the workpiece. The support member 121 and the mover module 120 can be formed separately or integrally. When the support member 121 and the mover module 120 are integrally formed, the mover module 120 has better integrity and does not require additional assembly. When the support member 121 and the mover module 120 are formed separately, different specifications of the support member 121 and the mover module 120 can be flexibly matched, thereby making the mover module 120 more adaptable and easier to maintain.

[0032] The moving body 122 is slidably disposed on the stator body 112, and the moving body 122 is magnetically coupled to the stator body 112. The stator body 112 drives the moving body 122 to slide by magnetic driving force. The moving body 122 may or may not be in contact with the stator body 112 when sliding. The magnetic driving force generated by the stator body 112 can not only drive the moving body 122 to move, but also drive the moving body 122 to levitate. When the vertically upward magnetic driving force is less than the weight of the moving module 120 and the workpiece, the moving body 122 and the stator body 112 are in contact. When the vertically upward magnetic driving force is greater than the weight of the moving module 120 and the workpiece, the moving body 122 and the stator body 112 are not in contact.

[0033] The support member 121 is provided with a clearance hole 121a. When the workpiece is placed on the support member 121, the bottom of the workpiece can be exposed through the clearance hole 121a, so that the bottom of the workpiece can be processed from below the support member 121. Of course, the size of the clearance hole 121a needs to be smaller than the size of the bottom of the workpiece to prevent the workpiece from falling out of the clearance hole 121a.

[0034] In summary, the carrier 121 of this embodiment is provided with a clearance hole 121a, eliminating the need for workpiece flipping during processing, thereby saving steps and improving production efficiency. Furthermore, workpiece flipping requires clamping equipment; the conveying system 100 of this embodiment does not require workpiece flipping during processing, thus eliminating the need for clamping equipment, saving costs, and reducing the space occupied by clamping equipment, improving space utilization. Finally, the clearance hole 121a on the carrier 121 also reduces the weight of the carrier 121, allowing for the transport of heavier workpieces while ensuring the carrier 121 reaches a preset strength, thereby improving the transport efficiency of the conveying system 100.

[0035] like Figure 1 As shown, in some embodiments, the shape of the vertical projection of the clearance hole 121a is a parallelogram, circle, rhombus, trapezoid, etc. Regular shapes such as parallelograms, circles, rhombuses, and trapezoids are relatively easier to process. Of course, the shape of the vertical projection of the clearance hole 121a can also be irregular, as long as it meets the requirements of the processing operation. Optionally, the shape of the vertical projection of the clearance hole 121a can be approximately the same as the bottom shape of the workpiece, so that the clearance hole 121a can expose as much of the bottom of the workpiece as possible, thereby facilitating the processing operation.

[0036] like Figure 1 As shown, in some embodiments, the ratio of the projected area of ​​the clearance hole 121a in the vertical direction to the projected area of ​​the support member 121 in the vertical direction is greater than or equal to 0.4 and less than or equal to 0.9. This makes the size of the clearance hole 121a suitable, allowing sufficient area to be exposed on the bottom of the workpiece for easy processing, while also ensuring the structural strength of the support member 121 so that it can support workpieces of common weight. Furthermore, the contact area between the workpiece and the support member 121 is suitable, preventing the workpiece from sliding on the support member 121. If the ratio of the projected area of ​​the clearance hole 121a in the vertical direction to the projected area of ​​the support member 121 in the vertical direction is less than 0.4, the exposed area of ​​the bottom of the workpiece will be small, which will restrict processing. If the ratio of the projected area of ​​the clearance hole 121a in the vertical direction to the projected area of ​​the support member 121 in the vertical direction is greater than 0.9, the structural strength of the support member 121 will be low, the weight of the workpiece that it can support will be limited, and the contact area between the support member 121 and the workpiece will be small, resulting in poor stability.

[0037] like Figure 1As shown, in some embodiments, the number of clearance holes 121a is one. A single clearance hole 121a is relatively easy to manufacture, and having a single clearance hole 121a allows for an increase in its size, thereby increasing the exposed area of ​​the workpiece bottom and reducing obstruction of the workpiece bottom. Of course, without affecting manufacturing, the number of clearance holes 121a can be multiple, thereby improving the structural strength of the support member 121.

[0038] like Figure 1 As shown, in some embodiments, the center point of the clearance hole 121a coincides with the center point of the support member 121, that is, the clearance hole 121a is located at the center of the support member 121. When the workpiece is placed on the support member 121, the workpiece is also approximately located at the center of the support member 121, thereby making the force on the support member 121 more uniform. When the support member 121 is a parallelogram, the center of the support member 121 is the intersection of the two diagonals; when the support member 121 is a circle, the center of the support member 121 is the center of the circle.

[0039] like Figure 2 As shown, in some embodiments, the conveying system 100 further includes an actuator 140, which is disposed below the carrier 121 corresponding to the clearance hole 121a. The actuator 140 can pass through the clearance hole 121a to process the bottom of the workpiece. The actuator 140 can be a component such as a robotic arm, and the processing method can be welding, drilling, etc., which are not limited here. When the actuator 140 is processing the bottom of the workpiece, the carrier 121 can stop moving, which helps to improve processing accuracy. The carrier 121 can also remain moving, in which case the actuator 140 can move synchronously with the carrier 121 to reduce the dwell time of the carrier 121 while ensuring processing accuracy and improving transportation efficiency. Alternatively, the actuator 140 can remain stationary, thereby using the relative movement between the workpiece and the actuator 140 to process the workpiece, for example, the actuator 140 can weld the workpiece while it is moving.

[0040] The conveying system 100 of this application embodiment can be used as an assembly line. The number of actuators 140 can be one or more. The processing technology of multiple actuators 140 can be different. When there are multiple actuators 140, the mover body 122 can carry the workpiece through multiple different actuators 140 to process the bottom of the workpiece in a variety of different ways in sequence.

[0041] like Figure 3 As shown, in some embodiments, the stator body 112 includes a vertically arranged armature winding 1121, which includes a plurality of coils arranged in phase sequence. By periodically energizing the armature winding 1121, the magnetic field around the armature winding 1121 can be changed.

[0042] The mover body 122 includes a connecting portion 1221 and two permanent magnet arrays 1222 connected to the connecting portion 1221. The two permanent magnet arrays 1222 are spaced apart. The permanent magnet arrays 1222 generate a constant magnetic field around the mover body 122. When the energizing direction and / or magnitude of the energizing current in the armature winding 1121 changes, a changing magnetic field can be generated around the armature winding 1121. This changing magnetic field interacts with the constant magnetic field, driving the mover body 122 to move relative to the stator body 112. Thus, the mover body 122 can move without being energized, reducing wiring complexity. It should be noted that the mover body 122 is not limited to using permanent magnet arrays 1222 to cooperate with the stator body 112. The mover body 122 can also use coils, etc., to achieve movement of the mover body 122 relative to the stator body 112 through the cooperation of the changing magnetic field around the mover body 122 and the changing magnetic field around the stator body 112. This is not a limitation.

[0043] The armature winding 1121 can extend out of the stator body 112, which is beneficial for both the magnetic coupling of the armature winding 1121 with the permanent magnet array 1222 and the heat dissipation of the armature winding 1121.

[0044] The two permanent magnet arrays 1222 and the connecting portion 1221 together define a vertically downward-facing groove 122a. The armature winding 1121 is disposed within the groove 122a. Thus, the mover module 120 can be directly attached to and detached from the stator module 110, facilitating the addition or removal of the mover module 120 or its maintenance. For example, when the number of mover modules 120 needs to be increased, the additional mover modules 120 can be directly placed on the stator module 110; when the number of mover modules 120 needs to be reduced, the excess mover modules 120 can be directly removed from the stator module 110. Furthermore, the vertical arrangement of the armature winding 1121 and the permanent magnet array 1222 minimizes the horizontal area occupied by the stator body 112 and the mover body 122, thereby reducing the horizontal dimensions of the conveyor system 100.

[0045] like Figure 3 As shown, in some embodiments, the mover body 122 is disposed on one side of the carrier 121 in the width direction KK, and the stator body 112 is disposed corresponding to the mover body 122. The width direction KK is perpendicular to the conveying direction SS of the mover module 120 and parallel to the horizontal plane. That is, the mover body 122 is disposed on one side of the carrier 121, which makes the structure of the stator module 110 simpler, smaller in size, and lower in cost.

[0046] Alternatively, there may be two mover bodies 122 and two stator bodies 112. The two mover bodies 122 are respectively disposed on both sides of the support member 121 in the width direction KK, and the two stator bodies 112 are respectively disposed corresponding to the two mover bodies 122. That is, the mover bodies 122 are disposed on both sides of the support member 121, so that the force on both sides of the support member 121 is more uniform and the driving force can be increased to transport heavy workpieces.

[0047] In some embodiments, the carrier 121 includes a bottom surface, a top surface, and a side surface connecting the bottom surface and the top surface, and the movable body 122 is connected to the side surface of the carrier 121. Thus, the movable body 122 is disposed on the side of the carrier 121 rather than at the bottom, thereby reserving space at the bottom of the carrier 121 to facilitate the arrangement of the actuator 140. Furthermore, the movable body 122 can be located away from the clearance hole 121a, thereby reducing the probability of the movable body 122 obstructing the clearance hole 121a, which is beneficial for the actuator 140 to process the workpiece.

[0048] like Figure 3 As shown, in some embodiments, the conveying system 100 further includes a support structure 130, which is disposed on the stator body 112. The support structure 130 abuts against the carrier member 121 to support the carrier member 121 in the vertical direction, and the carrier member 121 is slidably disposed on the support structure 130. By providing the support structure 130, the overall load-bearing capacity of the conveying system 100 can be improved. Moreover, since the support structure 130 is disposed on the stator body 112, it does not increase the weight of the mover body 122, thereby making the conveying system 100 more suitable for conveying heavier workpieces. In addition, since the conveying system 100 bears the load through the support structure 130 and the carrier member 121, the interaction force between the stator body 112 and the mover body 122 can be reduced, thereby improving the service life of the stator body 112 and the mover body 122. Furthermore, the levitation force of the stator body 112 on the mover body 122 can be reduced, thereby reducing energy consumption. Furthermore, by bearing the load through the support structure 130 and the bearing member 121, the stator body 112 and the mover body 122 can be spaced apart, thereby avoiding friction between the stator body 112 and the mover body 122, reducing wear between the stator body 112 and the mover body 122, and extending the service life of the stator body 112 and the mover body 122.

[0049] like Figure 3As shown, in some embodiments, the support structure 130 includes an adapter 131 and a roller 132. The adapter 131 is disposed on the stator body 112, and the roller 132 is disposed on the adapter 131. The connection between the adapter 131 and the stator body 112 can be by screwing, snap-fit, or other methods, and the connection between the roller 132 and the adapter 131 can be by screwing, snap-fit, or other methods, which are not limited here. The roller 132 is rolled relative to the bearing member 121, thereby reducing the resistance when the bearing member 121 moves.

[0050] Roller component 132 is typically difficult to directly fix to the stator body 112. By providing an adapter 131, roller component 132 can be fixed to the stator body 112 through the adapter 131, resulting in a better fixing effect. Moreover, after the adapter 131 is connected to the carrier component 121, the component formed by the adapter 131 and the carrier component 121 has higher strength and is less prone to deformation. By providing the adapter 131, the strength of the stator module 110 can be increased, allowing the stator module 110 to bear heavier weights. Furthermore, because the adapter 131 and the carrier component 121 are less prone to deformation, roller component 132 is less likely to deform or shift along with the adapter 131, thereby maintaining a suitable coupling gap between the stator body 112 and the mover body 122 and minimizing friction and collision between them.

[0051] like Figure 4 As shown, in some embodiments, the bottom surface of the support member 121 is provided with a protrusion 1211, and the support structure 130 abuts against and slides on the protrusion 1211. For example, the protrusion 1211 can be used to abut against the roller member 132. The protrusion 1211 can act as a reinforcing rib, thereby improving the structural strength of the support member 121 and enabling the support member 121 to bear heavier workpieces. Optionally, there are two protrusions 1211, which are spaced apart and close to the two opposite edges of the clearance hole 121a, so that the distance between the two protrusions 1211 is relatively small, that is, the two stress-bearing parts of the support member 121 are relatively close, which helps to improve the stress strength of the support member 121 and makes the support member 121 less prone to deformation.

[0052] In some embodiments, the bottom surface of the support member 121 is provided with a groove, and the support structure 130 abuts against the bottom wall of the groove and is slidably disposed in the groove. For example, the groove can be used to abut against the roller member 132. The groove can serve as a guide, thereby making it difficult for the support member 121 to move in the width direction KK. Optionally, there are two grooves, which are spaced apart and are respectively close to the two opposite edges of the clearance hole 121a, so that the distance between the two grooves is relatively small, that is, the two stress-bearing parts of the support member 121 are relatively close, which helps to improve the stress strength of the support member 121 and makes the support member 121 less prone to deformation.

[0053] like Figure 4 As shown, in some embodiments, there are two bases 111 and two stator bodies 112. The two stators are respectively disposed on the two bases 111, and the two bases 111 are spaced apart, so that space can be reserved between the two bases 111 to facilitate the arrangement of the actuator 140.

[0054] like Figure 5 As shown, in some embodiments, the conveying system 100 further includes a support structure 130, which includes a connector 131 and a roller 132. The roller 132 is disposed on the mover body 122, and the connector 131 is disposed on the stator body 112. The mover body 122 is rotatably disposed relative to the stator body 112. Exemplarily, the roller 132 is rotatably disposed on the connector 131, in which case the connector 131 can bear the roller 132 and distribute the pressure on the roller 132. Optionally, the connector 131 can also function as a guide rail to limit the movement trajectory of the roller 132.

[0055] In this embodiment, the roller component 132 is disposed on the moving body 122. The length of the moving body 122 in the conveying direction SS is usually less than the length of the stator body 112 in the conveying direction SS. Even if there are multiple moving bodies 122, the total length of the multiple moving bodies 122 in the conveying direction SS is still usually less than the length of the stator body 112 in the conveying direction SS. That is, the roller component 132 does not need to cover the stator body 112, thereby reducing the number of roller components 132 and reducing costs.

[0056] The above description is merely a preferred embodiment of this application and does not limit the patent scope of this application. Any equivalent structural transformations made based on the concept of this application and the contents of the specification and drawings of this application, or direct / indirect applications in other related technical fields, are included within the patent protection scope of this application.
