[0038] In order to more clearly illustrate the technical solutions in the embodiments of the present application or related technologies, the following will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present application. Obviously, the described embodiments are only a part of the embodiments of the present application, rather than all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present application.

[0039] In related technologies, some magnetic drive conveyor lines are provided with connection stators, and the connection stators can be connected to the stators on the conveyor line, so as to facilitate the transfer of workpieces on the loading line to the conveyor line. However, during the process of the connection stator picking up and feeding materials, the conveyor line will be in a disconnected state, resulting in a reduction in the conveying efficiency of the conveyor line.

[0040] In view of the above situation, please refer to Figures 1 - 3 , the present application proposes a transportation device 1, including a first conveyor line 10, a first connection module 20 and a second connection module 30. Workpieces are transported or processed on the first conveyor line 10. The first connection module 20 can be used to transfer external workpieces to the first conveyor line 10, and the second connection module 30 can be used to ensure the conveying continuity of the conveyor line.

[0041] like Figures 3 - 4 As shown, the first conveyor line 10 includes a stator assembly 11 and a mover assembly 12. The mover assembly 12 is magnetically coupled to the stator assembly 11 to drive the mover assembly 12 to slide relative to the stator assembly 11. The first conveyor line 10 can be a magnetic power conveyor line formed by splicing multiple stator assemblies 11. The permanent magnet on the mover assembly 12 and the armature winding on the stator assembly 11 drive the mover assembly 12 to slide by current excitation. The first conveyor line 10 may include multiple mover assemblies 12, which can be used to transport workpieces, and multiple mover assemblies 12 can carry workpieces to move on the stator assembly 11.

[0042] like Figures 3 - 6 As shown, the first conveyor line 10 has an avoidance space 13; the first docking module 20 includes a first docking stator 21 and a first track 22, the extension direction of the first track 22 is perpendicular to the conveying direction of the first conveyor line 10, and the first docking stator 21 is slidably connected to the first track 22 along the extension direction of the first track 22, so that the first docking stator 21 can slide in and out of the avoidance space 13; the second docking module 30 includes a second docking stator 31 and a second track 32, the extension direction of the second track 32 is perpendicular to the conveying direction of the first conveyor line 10 and the extension direction of the first track 22, and the second docking stator 31 is slidably connected to the second track 32 along the extension direction of the second track 32 to enter and exit the avoidance space 13.

[0043] The avoidance space 13 is used to accommodate the first docking stator 21 or the second docking stator 31, so that the first docking stator 21 or the second docking stator 31 is docked with the stator assembly 11 at the avoidance space 13, and after the stator assembly 11 is docked with the first docking stator 21 or the second docking stator 31, the mover assembly 12 can also be magnetically coupled with the first docking stator 21 and the second docking stator 31, so that the mover assembly 12 can smoothly perform the conveying work on the first conveyor line 10. The first conveyor line 10, the first track 22, and the second track 32 are arranged perpendicularly in each other in the extension direction, so as to prevent the first docking stator 21 and the second docking stator 31 from having position interference during the sliding docking process.

[0044] It should be noted that if Figure 5 As shown, when the first docking stator 21 is docked with the stator assembly 11, the second docking stator 31 slides along the second track 32 to leave the avoidance space 13, the first docking stator 21 slides into the avoidance space 13, and docks with the stator assembly 11, the first conveyor line 10 is in a complete line state, and at least one movable subassembly 12 on the stator assembly 11 slides to the first docking stator 21; then as shown Figure 6As shown, the first connecting stator 21 can carry the rotor assembly 12 and slide along the first track 22 away from the avoidance space 13, so as to facilitate the loading or unloading operation of the rotor assembly 12 on the first connecting stator 21, that is, to play the role of transporting workpieces. At the same time, the second connecting stator 31 slides along the second track 32 into the avoidance space 13 and is connected to the stator assembly 11, so that the first conveyor line 10 is again in the state of a complete line body, ensuring the conveying continuity of the first conveyor line 10, avoiding the situation of long-term disconnection of the first conveyor line 10, and improving the conveying efficiency of the first conveyor line 10.

[0045] In summary, the first connecting stator 21 and the second connecting stator 31 are alternately connected to the stator assembly 11 in a cycle. When one connecting stator is taking and delivering materials, the other connecting stator can be supplemented to the avoidance space 13 on the first conveyor line 10, that is, the other connecting stator can still be connected to the stator assembly 11, thereby ensuring the conveying continuity of the first conveyor line 10 and improving the conveying efficiency.

[0046] In some embodiments, as Figure 5 and Figure 7 shown, a positioning member 25 is provided on the first track 22, and a baffle 26 is provided on the first connecting stator 21. When the first connecting stator 21 slides along the first track 22 to a specified position, the baffle 26 on the first connecting stator 21 contacts the positioning member 25 on the first track 22, thereby preventing the first connecting stator 21 from continuing to slide on the first track 22, so that the first connecting stator 21 can stably stay at the specified position, and the positioning member 25 can also have a buffering effect to more stably make the first connecting stator 21 stay at the specified position. Herein, the specified position of the first connecting stator 21 means that when the first connecting stator 21 stays at this position, the rotor assembly 12 on the first connecting stator 21 can smoothly pick up the workpieces to be transported and processed.

[0047] Please refer to Figures 6 - 7 , in some embodiments of the present application, a first slide rail 23 is provided on one of the first track 22 and the first connecting stator 21, and a first slide groove 24 is provided on the other of the first track 22 and the first connecting stator 21, and at least part of the first slide rail 23 is received in the first slide groove 24.

[0048] It is easy to understand that taking the first slide rail 23 being provided on the first track 22 and the first sliding groove 24 being provided on the first connecting stator 21 as an example, the first connecting module 20 further includes a first driving member connected to the first connecting stator 21. The first driving member drives the first connecting stator 21 to slide on the first slide rail 23. The first driving member provides the power for the movement of the first connecting stator 21. The cooperation between the first slide rail 23 and the first sliding groove 24 provides movement guidance and limit for the first connecting stator 21, preventing the first connecting stator 21 from being misaligned during sliding.

[0049] Please refer to Figure 6 and Figure 8 , in some embodiments, a second slide rail 33 is provided on one of the second track 32 and the second connecting stator 31, and a second sliding groove 34 is provided on the other of the second track 32 and the second connecting stator 31. At least a part of the second slide rail 33 is received in the second sliding groove 34.

[0050] Similarly, taking the second slide rail 33 being provided on the second track 32 and the second sliding groove 34 being provided on the second connecting stator 31 as an example, the second connecting module 30 further includes a second driving member connected to the second connecting stator 31. The second driving member drives the second connecting stator 31 to slide on the second slide rail 33. The second driving member provides the power for the movement of the second connecting stator 31. The cooperation between the second slide rail 33 and the second sliding groove 34 provides movement guidance and limit for the second connecting stator 31, preventing the second connecting stator 31 from being misaligned during sliding.

[0051] Please refer to Figure 6 , in some embodiments of the present application, the first track 22 extends in the vertical direction, and the second track 32 extends in the horizontal direction, so as to reduce the position interference between the first connecting stator 21 and the second connecting stator 31 during the sliding connection process.

[0052] As Figures 3 - 6 shown, the mover assembly 12 is vertically located below the stator assembly 11. The transportation device 1 further includes a second conveying line 40. The second conveying line 40 is arranged at an interval from the first conveying line 10, and the second conveying line 40 is located below the first conveying line 10. The second conveying line 40 includes a transporting member 41. The transporting member 41 is used to carry and transport workpieces. The first track 22 extends from the first conveying line 10 to the second conveying line 40.

[0053] Specifically, the first connecting stator 21 can carry at least one rotor assembly 12 and slide along the first track 22, that is, the rotor assembly 12 gradually approaches the second conveyor line 40 until the first connecting stator 21 slides to a position where the rotor assembly 12 is close to the transport member 41, so as to facilitate the transfer of the workpiece on the transport member 41 to the rotor assembly 12. Subsequently, the first connecting stator 21 can carry the rotor assembly 12 and the transferred workpiece and slide together until the first connecting stator 21 is connected to the stator assembly 11 again. That is to say, the first connecting stator 21 can convey the workpiece at a lower position to a higher position, thereby completing a transfer of the workpiece from the second conveyor line 40 to the first conveyor line 10, so that the first conveyor line 10 can form an overhead conveyor line, facilitating the transportation and processing of the workpiece at a high altitude.

[0054] In some embodiments, as Figure 9 shown, the transport member 41 includes a bearing portion 411 and a limiting portion 412. The limiting portion 412 is arranged on the periphery of the bearing portion 411. The limiting portion 412 and the bearing portion 411 together form a receiving space for accommodating the workpiece. The bearing portion 411 provides support for the workpiece, and the limiting portion 412 limits the workpiece. Additionally, as Figure 1 shown, the transport device 1 further includes a frame body 61 and a base 62. The first conveyor line 10 is arranged on the frame body 61, and the second conveyor line 40 is arranged on the base 62. The first conveyor line 10 is located at the top of the frame body 61. The frame body 61 and the base 62 can be placed on the ground and fixedly connected to the ground to improve the overall stability of the transport device 1, and at the same time, it is also convenient for workers or manipulators to place the workpiece on the second conveyor line 40. The first conveyor line 10 and the second conveyor line 40 can be straight conveyor lines or circular conveyor lines.

[0055] Furthermore, please refer to Figure 9 , in some embodiments of the present application, the second conveyor line 40 further includes a third track 42. The transmission mode between the transport member 41 and the third track 42 is at least one of friction transmission, magnetic adsorption transmission, and fixed contact transmission. It can be understood that the transmission between the transport member 41 and the third track 42 can be carried out only in one of the above three transmission modes, or multiple transmission modes can be combined with each other for joint transmission.

[0056] It should be noted that the transport member 41 and the third track 42 can be driven by a variety of transmission methods, so that the transport member 41 can be used in different types of transmission lines. For example, taking the case where the transport member 41 and the third track 42 are driven by friction, the third track 42 may include a motor and a synchronous belt, a friction block may be provided on the transport member 41, the motor is used to drive the synchronous belt to move, and the friction block on the transport member 41 and the synchronous belt are frictionally matched, so that the movement of the synchronous belt can drive the movement of the friction block, and then drive the transport member 41 to move. For another example, taking the case where the transport member 41 and the third track 42 are driven by magnetic adsorption, a permanent magnet may be provided on the transport member 41, and the third track 42 may include a traveling magnetic field, the permanent magnet and the wave crest of the traveling magnetic field are coupled with each other, and the movement of the wave crest of the traveling magnetic field can generate an electromagnetic thrust, so that the permanent magnet on the transport member 41 drives the transport member 41 to move; or, the third track 42 may also include a three-phase AC coil, the three-phase AC coil is energized and coupled with the permanent magnet under current excitation to generate a driving force, thereby driving the transport member 41 to move. For another example, taking the example of fixed contact transmission between the transport member 41 and the third track 42, the third track 42 may include a rotating disk and a conveying block, and a plurality of conveying blocks are arranged in rotational symmetry about the axis of the rotating disk, and the rotating disk rotates around the axis, thereby driving the movement of the conveying block; a shift fork is arranged on the transport member 41, and when the shift fork runs to the friction disk, the rotation of the friction disk causes the conveying block to abut against the shift fork, and the shift fork moves with the rotation of the conveying block, thereby driving the movement of the transport member 41. For another example, taking the example of fixed contact transmission between the transport member 41 and the third track 42, the third track 42 may include a motor and a rack, and a tooth groove or a gear may be arranged on the transport member 41, and the motor is used to drive the rack to move, and the tooth groove or the gear on the transport member 41 cooperates with the rack, so that the rack can drive the transport member 41 to move; or, the third track 42 may also include a motor and a card slot, and a buckle may be arranged on the transport member 41, and the buckle is inserted into the card slot, and the card slot is driven to move by the motor, thereby moving the transport member 41.

[0057] See also Figure 10 In some embodiments of the present application, the mover assembly 12 includes a mover body 121 and a clamp 122. The mover body 121 is magnetically coupled to the stator assembly 11. The clamp 122 is located on the side of the mover body 121 away from the stator assembly 11 and is connected to the mover body 121. When the first docking stator 21 carries the mover assembly 12 close to the second conveyor line 40, the clamp 122 on the mover body 121 can clamp the workpiece on the transport member 41, so that the workpiece is transferred from the transport member 41 to the first conveyor line 10. Among them, the clamp 122 can provide a clamping force for the transportation of the workpiece to ensure the transportation stability of the workpiece.

[0058] Further, such as Figure 10As shown, the fixture 122 includes a first clamp 1221 and a second clamp 1222. Both the first clamp 1221 and the second clamp 1222 are slidably connected to the mover body 121. A transmission member 123 is provided on the mover body 121. The transmission member 123 is located between the first clamp 1221 and the second clamp 1222. The transmission member 123 is used to drive the first clamp 1221 and the second clamp 1222 to slide on the mover body 121.

[0059] Specifically, a clamping space 1223 for accommodating the workpiece is formed by enclosing between the first clamp 1221 and the second clamp 1222. The transmission member 123 can drive the first clamp 1221 and the second clamp 1222 to move relative to each other. When the first clamp 1221 and the second clamp 1222 move away from each other, the clamping space 1223 becomes larger, and the workpiece can smoothly enter the clamping space 1223. When the first clamp 1221 and the second clamp 1222 move towards each other, the clamping space 1223 shrinks, and the first clamp 1221 and the second clamp 1222 will abut against the side surface of the workpiece to clamp the workpiece. Wherein, blocking portions can be provided at the bottoms of both the first clamp 1221 and the second clamp 1222. After the first clamp 1221 and the second clamp 1222 clamp the workpiece, the blocking portions at the bottoms of the first clamp 1221 and the second clamp 1222 can contact the bottom of the workpiece, thereby preventing the workpiece from falling off from the clamping space 1223.

[0060] Furthermore, as Figure 10 shown, the transmission member 123 is a transmission gear. The transmission gear is rotatably connected to the mover body 121. Transmission racks 124 are provided on both the first clamp 1221 and the second clamp 1222. The transmission gear rotates, and the transmission gear meshes with the transmission racks 124 to drive the transmission racks 124 to move, thereby causing the first clamp 1221 and the second clamp 1222 to slide towards or away from each other.

[0061] In some embodiments of the present application, the mover assembly 12 further includes a roller (not shown in the figure). The roller is connected to the mover body 121. The roller is in rolling connection with the stator assembly 11. The mover body 121 and the stator assembly 11 are magnetically coupled to drive the mover assembly 12 to slide relative to the stator assembly 11.

[0062] Specifically, the stator assembly 11 includes an armature winding and a guide rail. A permanent magnet is provided on the mover body 121. The permanent magnet and the fixture 122 are respectively located on opposite sides of the mover body 121. The permanent magnet faces the armature winding. The roller is arranged on the periphery of the mover body 121 and is in rolling connection with the guide rail. The armature winding and the permanent magnet are magnetically coupled and drive the mover body 121 to move on the stator assembly 11, and at the same time can drive the roller to roll on the guide rail.

[0063] Please refer to Figure 2, in some embodiments of the present application, the transportation device 1 further includes a support frame 50, which is disposed adjacent to the first conveyor line 10, and both the first track 22 and the second track 32 are fixedly connected to the support frame 50. It is easy to understand that the support frame 50 can provide a setting basis and an installation space for the first track 22 and the second track 32.

[0064] It should be noted that the support frame 50 has a hollow area extending vertically. The first conveyor line 10 passes through the hollow area. The first connection stator 21 can slide up and down in the hollow area. When the second connection stator 31 is connected to the stator assembly 11, it is located in the hollow area. When the second connection stator 31 is disconnected from the stator assembly 11, it can slide out of the hollow area, thereby improving the protection of the support frame 50 for the first connection module 20 and the second connection module 30.
