Description

Technical Field

[0001] This invention relates to the field of magnetic drive transportation technology, and more specifically, to a magnetic drive transportation system. Background Technology

[0002] Currently, workpiece processing often requires multiple steps to be carried out sequentially. To avoid increasing production costs and reducing efficiency due to manual handling and transfer of workpieces, existing technologies typically employ automated transportation systems. However, the transportation method is usually conveyor belt transport, which generates significant vibration and dust pollution during transport. This can easily cause structural damage to the workpieces to be processed, pollute the environment, threaten the health of operators, and also results in poor transportation efficiency, reducing product processing and production efficiency. Summary of the Invention

[0003] This invention provides a magnetic drive transportation system to solve the problems of existing technologies that use conveyor belts to transport workpieces, which are prone to damage and have low transportation efficiency.

[0004] To address the above problems, the present invention provides a magnetic drive transportation system, the magnetic drive transportation system comprising:

[0005] The first conveyor line includes a first track stator, which has a material receiving position;

[0006] The second conveyor line is located above the first conveyor line and includes multiple second rail stators and multiple conversion stators. Each conversion stator is connected to two second rail stators at both ends. The first rail stator, the second rail stator and the conversion stator are all equipped with armature windings.

[0007] The moving module has a permanent magnet. When the permanent magnet is coupled to the corresponding armature winding, the moving module moves along the first or second conveyor line.

[0008] The lifting unit includes a connecting rail stator and a lifting mechanism. The lifting mechanism is used to drive the connecting rail stator to move between the first conveyor line and the second conveyor line. The connecting rail stator is used to dock with the first rail stator and the second rail stator.

[0009] Furthermore, the magnetic drive transport system also includes a pallet structure, which is fixedly connected to the moving module and is used to carry the workpiece to be processed.

[0010] Furthermore, the magnetic drive transport system also includes an outer casing and a controller. The interior of the outer casing is divided into a first working area and a second working area. The first conveyor line, the second conveyor line, the moving module, and the pallet structure are all located in the first working area. The controller is located in the second working area and is electrically connected to the first and second conveyor lines.

[0011] Furthermore, the pallet structure includes a base plate and multiple baffles. The base plate is connected to the moving sub-module, and the multiple baffles are fixedly arranged around the side of the base plate away from the moving sub-module. Multiple limiting holes are spaced apart on the base plate. The limiting holes are used to fix the workpiece to be processed onto the pallet structure with fasteners.

[0012] Furthermore, the moving part module includes a moving part body, multiple legs, multiple limit bearings, and multiple rollers. The multiple legs and multiple rollers are located on the side of the moving part body away from the pallet structure. One end of each leg is connected to the moving part body, and the other end is fitted with a limit bearing. Each leg and the corresponding limit bearing are coaxially arranged. The multiple rollers are used to support the moving part body to move along the first conveyor line or the second conveyor line.

[0013] Furthermore, the magnetic drive transport system also includes a first track support, a first conveyor line is set on the first track support, and first limiting grooves are provided on both sides along the conveying direction of the moving sub-module. At least part of the limiting bearing is located in the first limiting groove, and the outer peripheral surface of the limiting bearing is in contact with the inner wall of the first limiting groove.

[0014] Furthermore, the magnetic drive transport system also includes a second track support, a second conveyor line is set on the second track support, and second limiting grooves are provided on both sides along the conveying direction of the moving sub-module. At least part of the limiting bearing is located in the second limiting groove, and the outer peripheral surface of the limiting bearing is in contact with the inner wall of the second limiting groove.

[0015] Furthermore, the pallet structure also includes a sensing device and a transmitting device, both of which are mounted on the base plate. The sensing device is used to sense when the workpiece to be processed is placed on the pallet structure, and the transmitting device is used to receive the radio waves emitted by the sensing device and transmit signals to the controller.

[0016] Furthermore, the tray structure also includes an energy storage device and multiple positioning blocks. The energy storage device and multiple positioning blocks are both mounted on the base plate, with the multiple positioning blocks arranged around the energy storage device. The energy storage device is used to power the sensing device and the transmitting device.

[0017] Furthermore, multiple positioning blocks are in contact with the energy storage device.

[0018] Furthermore, the magnetic drive transport system also includes an operating table and a robotic arm. The operating table has a first working position and a second working position. The first working position is used to place the workpiece to be processed, and the second working position is used to place the processed workpiece. The robotic arm is located between the operating table and the first conveyor line and is used to grab the workpiece to be processed from the first working position and place it at the receiving position.

[0019] Furthermore, the lifting unit also includes a drive motor and a connecting slider. The drive motor is located in the second working area and is electrically connected to the lifting mechanism. It is used to drive the connecting rail stator to move back and forth along the height direction of the lifting mechanism. One side of the connecting slider is connected to the lifting mechanism, and the other side of the connecting slider is connected to the connecting rail stator.

[0020] Furthermore, the lifting mechanism includes a frame, a movable pulley block, a fixed pulley block, and a conveyor belt. The frame is located at the end of the first conveyor line and / or the second conveyor line and is fixedly connected to the outer casing. The movable pulley block is located at one end of the frame near the first conveyor line, and the fixed pulley block is located at the other end of the frame. The conveyor belt passes around the movable pulley block, the frame, and the fixed pulley block in sequence, and one side of the connecting slider is connected to the conveyor belt.

[0021] By applying the technical solution of this invention, a first conveyor line and a second conveyor line are set up to avoid mutual interference between different processes, realize zoned processing, and ensure the processing quality of the workpiece in each process. The second conveyor line is located above the first conveyor line, which optimizes the spatial layout of the device and improves the utilization rate of its longitudinal space. The two ends of each conversion stator are connected to two second track stators respectively, which can form multiple transport lines, increase the processing points, meet different processing needs, increase the number of workpieces that can be processed at the same time, and provide waiting processing positions, thereby improving the processing efficiency and applicability of the magnetic drive transport system. The lifting part is set up to realize the flexible movement of the workpiece between the first conveyor line and the second conveyor line. Through the setting of permanent magnets and armature windings, magnetic drive transport of the mover module on the first track stator, the second track stator and the conversion stator is realized, which improves the transport efficiency and stability, reduces vibration and dust generation during transport, ensures the integrity of the workpiece structure, and improves the workpiece transport efficiency.

[0053] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. The following description of at least one exemplary embodiment is merely illustrative and is in no way intended to limit the present invention or its application or use. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0054] like Figures 1 to 8 As shown, an embodiment of the present invention provides a magnetic drive transportation system, which includes:

[0055] The first conveyor line 10 includes a first track stator 11, which has a receiving position.

[0056] The second conveyor line 20 is located above the first conveyor line 10 and includes multiple second rail stators 21 and multiple changeover stators 22. Each changeover stator 22 is connected to two second rail stators 21 at both ends. The first rail stator 11, the second rail stator 21 and the changeover stator 22 are all provided with armature windings 81.

[0057] The moving module 30 has a permanent magnet 82. When the permanent magnet 82 is coupled with the corresponding armature winding 81, the moving module 30 moves along the first conveyor line 10 or the second conveyor line 20.

[0058] The lifting unit 40 includes a connecting rail stator 41 and a lifting mechanism 42. The lifting mechanism 42 is used to drive the connecting rail stator 41 to move between the first conveyor line 10 and the second conveyor line 20. The connecting rail stator 41 is used to dock with the first rail stator 11 and the second rail stator 21.

[0059] In this embodiment, by setting up the first conveyor line 10 and the second conveyor line 20, the mutual influence between different processes is avoided, and zoned processing is realized, ensuring the processing quality of the workpiece in each process. The second conveyor line 20 is located above the first conveyor line 10, which optimizes the spatial layout of the device and improves the utilization rate of its longitudinal space. Each conversion stator 22 is connected to two second track stators 21 at both ends, forming multiple transport lines, increasing the number of processing points, meeting different processing needs, increasing the number of workpieces that can be processed at the same time, and providing a waiting position, thereby improving the processing efficiency and applicability of the magnetic drive transport system. Moreover, by setting up the lifting part 40, the workpiece can move flexibly between the first conveyor line 10 and the second conveyor line 20. By setting up the permanent magnet 82 and the armature winding 81, the magnetic drive transport of the mover module 30 on the first track stator 11, the second track stator 21 and the conversion stator 22 is realized, improving the transport efficiency and stability, reducing vibration and dust generation during transport, ensuring the integrity of the workpiece structure, and improving the workpiece transport efficiency.

[0060] The lifting unit 40 has two parts, which are respectively set at both ends of the first conveyor line 10 and / or the second conveyor line 20. This ensures that the force on the workpiece is symmetrical when it moves between the first conveyor line 10 and the second conveyor line 20, avoiding workpiece tilting or unstable transportation, and further improving transportation efficiency and stability.

[0061] like Figure 5 As shown, the magnetic drive transport system also includes a pallet structure 50, which is fixedly connected to the moving sub-module 30. The pallet structure 50 is used to carry the workpiece to be processed.

[0062] In this embodiment, by fixing the pallet structure 50 to the moving submodule 30, the pallet structure 50 can move synchronously with the moving submodule 30 on the magnetic drive track, thereby achieving the overall carrying and conveying of the workpiece to be processed. Compared with the traditional conveyor belt method that relies on the friction between the conveyor belt and the workpiece for transmission, in this solution, the workpiece is directly placed on the pallet structure 50 and moves as a whole with the moving submodule 30, avoiding relative sliding between the workpiece and the conveyor belt, reducing vibration and impact during transportation, and reducing the mechanical stress on the structure of the workpiece to be processed. This reduces the risk of deformation, loosening, or damage to the workpiece during transportation, and improves the stability and safety of the transportation process. Moreover, the pallet structure 50 provides a relatively closed and stable carrying platform for the workpiece to be processed, and can be adapted to the specific shape of the workpiece to achieve workpiece limiting and positioning. This maintains the stability of the workpiece and avoids displacement or tipping during transportation, thereby improving the alignment accuracy and processing quality of subsequent processing steps and enhancing the consistency of overall production.

[0063] Furthermore, since the pallet structure 50 and the moving module 30 can form an integrated transportation unit, independent drive and precise control of a single workstation can be achieved, enabling each pallet structure 50 to operate independently according to a preset path and speed. This improves the system's scheduling flexibility and transportation efficiency, avoids the cycle time limitation problem caused by the overall operation of traditional conveyor belts, and improves the efficiency of product processing and production.

[0064] like Figure 1 and Figure 3 As shown, the magnetic drive transport system also includes an outer casing 61 and a controller 62. The interior of the outer casing 61 is divided into a first working area 611 and a second working area 612. The first conveyor line 10, the second conveyor line 20, the moving module 30 and the pallet structure 50 are all located in the first working area 611. The controller 62 is located in the second working area 612 and is electrically connected to the first conveyor line 10 and the second conveyor line 20.

[0065] In this embodiment, by setting up the outer casing 61 and arranging the first conveyor line 10, the second conveyor line 20, the moving module 30, and the tray structure 50 within the first working area 611, the magnetic drive transport component and the workpiece carrying component are placed in a relatively enclosed spatial environment. This structurally isolates and protects the transport process, preventing external dust from entering the transport area and reducing the outward diffusion of dust that may be generated during transport, thereby improving the cleanliness of the production environment and reducing the risk of environmental pollution. Furthermore, by placing the controller 62 in the second working area 612 and electrically connecting the controller 62 to the first conveyor line 10 and the second conveyor line 20, spatial separation of the control system and the transport actuator is achieved. This reduces the impact of vibration, electromagnetic interference, and dust generated during transport on the controller 62, thereby improving the stability and reliability of the control system, extending the service life of electrical components, reducing the failure rate, and improving the overall safety of the system.

[0066] like Figure 5 As shown, the pallet structure 50 includes a base plate 51 and multiple baffles 52. The base plate 51 is connected to the moving sub-module 30. The multiple baffles 52 are fixedly arranged around the side of the base plate 51 away from the moving sub-module. Multiple limiting holes 53 are spaced apart on the base plate 51. The limiting holes 53 are used to fix the workpiece to be processed onto the pallet structure 50 by fasteners.

[0067] In this embodiment, by setting a base plate 51 and connecting it to the moving sub-module 30, the base plate 51, as a supporting foundation, moves synchronously with the moving sub-module 30, providing a stable and rigid support platform for the workpiece to be processed. Compared with the flexible bearing method of traditional conveyor belts, the base plate 51 can reduce the vibration and displacement caused by the elastic deformation of the belt, improve the stability of the workpiece during transportation, and reduce the impact generated during transportation. Moreover, multiple baffles 52 are fixedly arranged around the side of the base plate 51 away from the moving sub-module 30, forming a confining space from a structural perspective, which can play a circumferential restraint role on the workpiece to be processed. Thus, even during the start-stop or acceleration / deceleration conditions during transportation, the baffles 52 can prevent the workpiece from sliding laterally or tipping over, thereby improving the safety of the transportation process and reducing the risk of damage caused by workpiece displacement.

[0068] In addition, multiple limiting holes 53 are provided at intervals on the base plate 51, and the workpiece to be processed is fixed on the pallet structure 50 by fasteners. This can further eliminate the relative displacement between the workpiece and the pallet structure 50 during transportation, reduce vibration transmission and impact, and improve the overall transportation stability.

[0069] like Figure 5 and Figure 6 As shown, the moving part module 30 includes a moving part body 31, multiple support legs 32, multiple limit bearings 33, and multiple rolling wheels 34. The multiple support legs 32 and multiple rolling wheels 34 are located on the side of the moving part body 31 away from the pallet structure 50. One end of each support leg 32 is connected to the moving part body 31, and the other end is fitted with a limit bearing 33. Each support leg 32 and the corresponding limit bearing 33 are coaxially arranged. The multiple rolling wheels 34 are used to support the moving part body 31 to move along the first conveyor line 10 or the second conveyor line 20.

[0070] In this embodiment, multiple rolling wheels 34 are provided on the side of the moving body 31 away from the pallet structure 50. Compared with the traditional sliding friction or belt friction drive method, when the moving body 31 moves along the first conveyor line 10 or the second conveyor line 20, the motion resistance and friction loss are reduced, the vibration and noise during operation are reduced, and the motion stability and transmission efficiency are improved, thereby improving the overall transportation efficiency and extending the service life of the system. Moreover, by providing multiple support legs 32 on the moving body 31, and fitting a limiting bearing 33 at the end of each support leg 32, with the support leg 32 and the limiting bearing 33 coaxially arranged, the limiting bearing 33 can play a lateral guiding and limiting role. During the operation of the moving module 30, the limiting bearing 33 can provide lateral constraint on the moving body 31, preventing it from swaying or shifting laterally in high-speed or variable-speed operation, thereby ensuring that the moving module 30 runs stably along the predetermined trajectory and improving positioning accuracy and path repeatability accuracy.

[0071] Furthermore, the distributed arrangement of multiple support legs 32 and multiple limiting bearings 33 enables the moving submodule 30 to form a multi-point support and multi-point limiting structure in both the longitudinal and transverse directions, enhancing the overall structural rigidity and stress balance. Even under conditions of bearing heavy workpieces or frequent start-stop operations, it can effectively distribute the load, reduce the phenomenon of single-point stress concentration, reduce structural deformation and wear, and improve the reliability and safety of system operation.

[0072] like Figure 7 As shown, the magnetic drive transport system also includes a first track support 71, a first conveyor line 10 is disposed on the first track support 71, and first limiting grooves 711 are provided on both sides along the conveying direction of the moving sub-module. At least part of the limiting bearing 33 is located in the first limiting groove 711, and the outer peripheral surface of the limiting bearing 33 is in contact with the inner sidewall of the first limiting groove 711.

[0073] In this embodiment, by setting a first limiting groove 711 on the first track support 71 that matches the running direction of the moving sub-module 30, and by embedding the limiting bearing 33 in the first limiting groove 711 to form a mating relationship, the moving sub-module 30 is subjected to lateral guiding constraints from the side wall of the first limiting groove 711 during the conveying process. This can limit the displacement of the moving sub-module 30 in the lateral direction and prevent the moving sub-module 30 from swaying or deviating during high-speed operation or frequent start-stop states. This ensures that it runs stably and accurately along the first conveying line 10, and improves the straightness and repeatability of the conveying path.

[0074] like Figure 8 As shown, the magnetic drive transport system also includes a second track support 72, a second conveyor line 20 is disposed on the second track support 72, and a second limiting groove 721 is provided on both sides along the conveying direction of the moving sub-module. At least part of the limiting bearing 33 is located in the second limiting groove 721, and the outer peripheral surface of the limiting bearing 33 is in contact with the inner wall of the second limiting groove 721.

[0075] In this embodiment, by placing the second conveyor line 20 on the second track support 72, the second conveyor line 20 obtains stable support, improving its overall rigidity and resistance to deformation. During the operation of the moving submodule 30 carrying the workpiece, the second track support 72 can provide a stable support foundation for the moving submodule 30, avoiding vibration or deformation caused by insufficient rigidity of the track structure, thereby ensuring the smoothness of the transportation process.

[0076] Furthermore, by setting second limiting grooves 721 on both sides of the second conveyor line 20 and embedding the limiting bearings 33 therein to form a rolling contact fit, the moving sub-module 30 can also obtain lateral guidance and limiting constraints when running on the second conveyor line 20. This can prevent the moving sub-module 30 from shifting or swinging in the lateral direction, and ensure that the moving sub-module 30 runs accurately along the predetermined trajectory, thereby improving the path accuracy and repeatability of the moving sub-module 30 on the second conveyor line 20.

[0077] like Figure 5 As shown, the pallet structure 50 also includes a sensing device 54 and a transmitting device 55. Both the sensing device 54 and the transmitting device 55 are disposed on the base plate 51. The sensing device 54 is used to sense that the workpiece to be processed is placed on the pallet structure 50, and the transmitting device 55 is used to receive the radio waves emitted by the sensing device 54 and transmit signals to the controller 62.

[0078] In this embodiment, by setting a sensing device 54 on the pallet structure 50, the placement status of the workpiece to be processed can be detected in real time, realizing automatic identification of whether the workpiece is correctly loaded. This can avoid the occurrence of empty operation or missing workpieces, thereby reducing ineffective transportation and improving the operating efficiency of the production line. Moreover, by setting a transmitting device 55, which receives the radio waves emitted by the sensing device 54 and sends a signal to the controller 62, a wireless communication channel is established between the pallet structure 50 and the controller 62, realizing the real-time transmission of workpiece status information. This avoids the need to lay complex cables for connection between moving parts, reduces wiring difficulty and failure risk, and improves the simplicity and reliability of the overall system structure.

[0079] In addition, by monitoring and providing feedback on the loading status of the workpiece in real time, a signal can be sent in a timely manner when abnormal situations occur, such as the workpiece not being placed in place or falling off, and the controller 62 can take corresponding control measures, thereby reducing the risk of damage to the workpiece caused by abnormal operation and improving the safety of system operation.

[0080] like Figure 5 As shown, the tray structure 50 also includes an energy storage device 56 and multiple positioning blocks 57. The energy storage device 56 and multiple positioning blocks 57 are both disposed on the base plate 51. The multiple positioning blocks 57 are arranged around the energy storage device 56. The energy storage device 56 is used to supply power to the sensing device 54 and the transmitting device 55.

[0081] In this embodiment, by setting an independent energy storage device 56 on the tray structure 50 to provide power to the sensing device 54 and the transmitting device 55, the tray structure 50 forms a relatively independent power supply unit. This eliminates the need for complex cables or sliding conductive devices between the moving submodule 30 and the external control system, thus avoiding wire wear, poor contact, or electrical faults caused by reciprocating motion, improving the reliability and stability of system operation, and simplifying the overall wiring structure while reducing maintenance costs. Furthermore, multiple positioning blocks 57 are arranged around the energy storage device 56, providing a stable limiting and support structure for the energy storage device 56 on the base plate 51. During the operation and start-up / stop of the moving submodule 30, even with vibration or acceleration / deceleration impacts, the positioning blocks 57 can fix and protect the energy storage device 56, preventing displacement or loosening, thereby improving the safety and durability of the power supply system.

[0082] In addition, the power storage device 56 and the positioning block 57 are both set on the base plate 51, so that the power supply component and the detection and communication component are integrated into a single structure. The structure is compact, occupies little space, does not affect the load-bearing function of the tray structure 50, and maintains a reasonable distribution of the overall center of gravity, which can improve the balance and stability of the moving submodule 30 during operation.

[0083] like Figure 5 As shown, multiple positioning blocks 57 are in contact with the energy storage device 56.

[0084] In this embodiment, by making multiple positioning blocks 57 form an abutting relationship with the energy storage device 56, the energy storage device 56 is directly supported and restricted by the positioning blocks 57 in multiple circumferential directions. In this way, even if there are acceleration and deceleration impacts or micro-vibrations during the operation of the moving submodule 30, the positioning blocks 57 can generate a stable constraint force on the energy storage device 56 through the abutting method, preventing the energy storage device 56 from shaking or displacing on the base plate 51, and improving the installation stability of the energy storage device 56.

[0085] like Figure 2 As shown, the magnetic drive transport system also includes an operating table 63 and a robotic arm 64. The operating table 63 has a first working position 631 and a second working position 632. The first working position 631 is used to place the workpiece to be processed, and the second working position 632 is used to place the processed workpiece. The robotic arm 64 is located between the operating table 63 and the first conveyor line 10 and is used to grab the workpiece to be processed from the first working position 631 and place it at the receiving position.

[0086] In this embodiment, by setting a first working position 631 on the operating table 63 for placing the workpiece to be processed and a second working position 632 for placing the processed workpiece, the workpiece to be processed and the processed workpiece are placed separately in space. This avoids mixing of workpieces, improves the management standardization and orderliness of the production site, and reduces the risk of processing errors caused by misplacement or confusion of workpieces. Moreover, by setting the robotic arm 64 between the operating table 63 and the first conveyor line 10, the robotic arm 64 can grab the workpiece to be processed from the first working position 631 and place it at the receiving position, realizing the automatic transfer of workpieces from the manual placement area to the magnetic drive transport system. Compared with the traditional manual handling method, the solution in this application can reduce the degree of human intervention, reduce labor intensity, improve operational safety, and avoid workpiece collisions or drops caused by unstable manual operation, thereby improving the stability and reliability of the workpiece transfer process.

[0087] Furthermore, by dividing the work between the first workstation 631 and the second workstation 632, the operating table 63 can perform both loading and unloading functions, forming a relatively integrated loading and unloading platform. This can shorten the flow path of workpieces between different processes and improve production cycle time. At the same time, the robotic arm 64 can be coordinated with the magnetic drive transportation system to achieve continuous and cycle-based operations, thereby improving overall production efficiency.

[0088] like Figure 4 As shown, the lifting part 40 also includes a drive motor 43 and a connecting slider. The drive motor 43 is located in the second working area 612. The drive motor 43 is electrically connected to the lifting mechanism 42 and is used to drive the connecting rail stator 41 to move back and forth along the height direction of the lifting mechanism 42. One side of the connecting slider is connected to the lifting mechanism 42, and the other side of the connecting slider is connected to the connecting rail stator 41.

[0089] In this embodiment, by placing the drive motor 43 in the second working area 612 and electrically connecting it to the lifting mechanism 42, the drive motor 43 drives the connecting rail stator 41 to reciprocate along the height direction of the lifting mechanism 42. This allows the connecting rail stator 41 to automatically adjust between different height positions, realizing the conveying of workpieces between the first conveyor line 10 and the second conveyor line 20. This allows for dynamic adjustment according to actual needs, improving the docking accuracy between different conveyor lines and ensuring a smooth transition of the moving module 30 during cross-line operation. Moreover, the drive motor 43 enables electronic control, making the lifting process of the connecting rail stator 41 controllable, adjustable, and highly repeatable. This facilitates automated control and programmed operation, avoiding errors caused by manual adjustment and improving the overall consistency and reliability of the system. Simultaneously, placing the drive motor 43 in the second working area 612 isolates the power control components from the transport mechanism in the first working area 611, reducing the adverse effects of dust, vibration, and electromagnetic interference on the drive motor 43 and its electrical components, and improving the service life and operational safety of the electrical system.

[0090] Furthermore, by setting a connecting slider, one side of the connecting slider is connected to the lifting mechanism 42, and the other side is connected to the connecting rail stator 41, so that the connecting rail stator 41 can obtain stable guidance and support during the lifting process. The connecting slider can also slide smoothly on the lifting mechanism 42, reducing swaying or tilting, ensuring the stability of the connecting rail stator 41 during the lifting process, thereby improving the smoothness of operation of the moving module 30 when crossing the connecting area.

[0091] like Figure 4 As shown, the lifting mechanism 42 includes a frame 421, a movable pulley block 422, a fixed pulley block 423, and a conveyor belt 424. The frame 421 is located at the end of the first conveyor line 10 and / or the second conveyor line 20, and is fixedly connected to the outer shell 61. The movable pulley block 422 is located at one end of the frame 421 near the first conveyor line 10, and the fixed pulley block 423 is located at the other end of the frame 421. The conveyor belt 424 passes around the movable pulley block 422, the frame 421, and the fixed pulley block 423 in sequence, and one side of the connecting slider is connected to the conveyor belt 424.

[0092] In this embodiment, by setting a frame 421 as the support structure for the lifting mechanism 42, and positioning the frame 421 at the end of the first conveyor line 10 and / or the second conveyor line 20, and fixing it to the outer casing 61, the lifting mechanism 42 forms a stable installation foundation. This enhances the overall rigidity and vibration resistance, preventing swaying or deviation during lifting, thereby improving the stability and positioning accuracy of the connecting track stator 41 during lifting. Simultaneously, by setting movable pulley blocks 422 and fixed pulley blocks 423 at both ends of the frame 421, and having the conveyor belt 424 sequentially pass around the movable pulley blocks 422, the frame 421, and the fixed pulley blocks 423, a transmission structure is formed where pulleys and the belt cooperate. This disperses the transmission load, reduces the phenomenon of concentrated force at a single point, and improves the load-bearing capacity and smooth operation of the lifting mechanism 42.

[0093] Furthermore, by connecting one side of the connecting slider to the conveyor belt 424, when the drive motor 43 drives the conveyor belt 424, it can synchronously drive the connecting slider and the connecting track stator 41 to move along the height direction. Since the track drive has the characteristics of smooth transmission, low noise and low impact, it can reduce the vibration during the lifting process, thereby ensuring that the moving module 30 can smoothly transition when crossing different conveyor lines, and improving the continuity and reliability of the overall system operation.

[0094] like Figure 2 As shown, the magnetic drive transport system also includes an air purifier 65, which is installed on the housing 61 and used to purify the air in the second working area 612. The air purifier 65 can absorb and remove dust generated during transport, preventing environmental pollution and threats to the health of operators.

[0095] It should be noted that the terminology used herein is for the purpose of describing particular embodiments only and is not intended to limit the exemplary embodiments according to this application. As used herein, the singular form is intended to include the plural form as well, unless the context clearly indicates otherwise. Furthermore, it should be understood that when the terms "comprising" and / or "including" are used in this specification, they indicate the presence of features, steps, operations, devices, components, and / or combinations thereof.

[0096] Unless otherwise specifically stated, the relative arrangement, numerical expressions, and values ​​of the components and steps set forth in these embodiments do not limit the scope of the invention. It should also be understood that, for ease of description, the dimensions of the various parts shown in the drawings are not drawn to actual scale. Techniques, methods, and devices known to those skilled in the art may not be discussed in detail, but where appropriate, such techniques, methods, and devices should be considered part of the specification. In all examples shown and discussed herein, any specific values ​​should be interpreted as merely exemplary and not as limitations. Therefore, other examples of exemplary embodiments may have different values. It should be noted that similar reference numerals and letters in the following figures denote similar items; therefore, once an item is defined in one figure, it need not be further discussed in subsequent figures.

[0097] In the description of this invention, it should be understood that the orientation or positional relationship indicated by directional terms such as "front, back, up, down, left, right", "horizontal, vertical, horizontal" and "top, bottom" is generally based on the orientation or positional relationship shown in the accompanying drawings, and is only for the convenience of describing this invention and simplifying the description. Unless otherwise stated, these directional terms do not indicate or imply that the device or element referred to must have a specific orientation or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation on the scope of protection of this invention; the directional terms "inner" and "outer" refer to the inner and outer contours relative to the outline of each component itself.

[0098] For ease of description, spatial relative terms such as "above," "on top of," "on the upper surface of," "above," etc., are used herein to describe the spatial positional relationship of a device or feature as shown in the figures to other devices or features. It should be understood that spatial relative terms are intended to encompass different orientations in use or operation beyond the orientation of the device as described in the figures. For example, if the device in the figures were inverted, a device described as "above" or "on top of" other devices or structures would subsequently be positioned as "below" or "under" other devices or structures. Thus, the exemplary term "above" can include both "above" and "below." The device may also be positioned in other different ways (rotated 90 degrees or in other orientations), and the spatial relative descriptions used herein will be interpreted accordingly.

[0099] Furthermore, it should be noted that the use of terms such as "first" and "second" to define components is merely for the purpose of distinguishing the corresponding components. Unless otherwise stated, the above terms have no special meaning and therefore should not be construed as limiting the scope of protection of this invention.
