Description

Technical Field

[0001] This application relates to the field of magnetic drive conveying devices, and more particularly to a magnetic drive conveying system. Background Technology

[0002] In existing transportation systems, the conveyor system includes a conveyor line, a controller, and a mover. The conveyor line and the mover are magnetically coupled to achieve the movement of the mover. The controller controls the conveyor line to change the movement state of the mover. Typically, the conveyor line includes multiple stators connected in series by cables, and the stators and controller communicate via cables. When a cable fails, communication between the controller and the stators ceases, causing the conveyor system to malfunction. During cable repair, the conveyor system needs to be shut down, resulting in wasted time. Utility Model Content

[0003] This application provides a magnetic drive conveyor system designed to reduce the impact of cable faults between the controller and the conveyor line on the magnetic drive conveyor system.

[0004] This application provides a magnetic drive conveying system, which includes a stator module, a controller, and a cable group. The cable group connects at least the stator module and the controller to enable electrical communication between them. The cable group includes a main cable and a redundant cable. The stator module includes a first switch module for selecting the main cable and the redundant cable, and / or the controller includes a second switch module for selecting the main cable and the redundant cable.

[0005] In the magnetic drive conveyor system of this application embodiment, the cable group connects at least the stator module and the controller. The cable group includes a main cable and redundant cables. The main cable connects the controller to all stator modules, enabling information transmission between the controller and stator modules in the magnetic drive conveyor system and ensuring the integrity of information transmission. The redundant cables connect stator modules to each other or between the controller and stator modules. Furthermore, at least one of the stator modules and the controller is equipped with a switch module for selecting between the main cable and the redundant cables. With this configuration, when the main cable between the controller and the stator module fails, the switch module can disconnect the faulty cable while simultaneously selecting the redundant cables to ensure information transmission between the stator module and the controller, thus maintaining the normal operation of the magnetic drive conveyor system and avoiding downtime due to main cable failure. Moreover, since the switch module selects the redundant cables and disconnects the faulty main cable, the magnetic drive conveyor system can continue to operate normally without downtime, and the faulty cable can be repaired, thus avoiding reduced process efficiency due to maintenance time and minimizing wasted time. Therefore, the solution in this application can reduce the impact of cable faults between the controller and the conveyor line on the magnetic drive conveyor system.

[0006] In some embodiments of this application, when the stator module includes the first switch module, the first switch module has a first position and a second position. When the first switch module is in the first position, the main cable is turned on, and when the first switch module is in the second position, the redundant cable is turned on.

[0007] The first switch module is a mechanical switch with multiple contacts. The actuator, main cable, and redundant cable in the stator module are each connected to a corresponding contact. By adjusting the position of the conductive element, the first switch module can activate the corresponding contact, thereby enabling selective conduction between the actuator, the main cable, and the redundant cable.

[0008] In some embodiments of this application, when the controller includes a second switch module, the second switch module has a third position and a fourth position. When the second switch module is in the third position, the main cable is turned on, and when the second switch module is in the fourth position, the redundant cable is turned on.

[0009] The second switch module is a mechanical switch with multiple contacts. The control unit, main cable, and redundant cable in the controller are each connected to a corresponding contact. By adjusting the position of the conductive components, the second switch module can activate the corresponding contact, thereby enabling selective connection between the control unit, the main cable, and the redundant cable.

[0010] In some embodiments of this application, the main cable and the redundant cable are connected in series between the stator module and the controller; the main cable includes a first sub-cable and a second sub-cable, the first sub-cable being used to connect two adjacent stator modules, and the second sub-cable being used to connect the stator module and the controller; the redundant cable includes a third sub-cable and a fourth sub-cable, the third sub-cable being used to connect two adjacent stator modules, and the fourth sub-cable being used to connect the stator module and the controller.

[0011] Typically, a conveyor line includes multiple stator modules, and these modules need to exchange information. For example, commands issued by the controller need to be transmitted to each stator module via cable groups. Based on these requirements, the main cable includes a first sub-cable and a second sub-cable. The first sub-cable connects two adjacent stator modules, and the second sub-cable connects the stator module to the controller. Similarly, redundant cables include a third sub-cable and a fourth sub-cable. The third sub-cable connects two adjacent stator modules, and the fourth sub-cable connects the stator module to the controller.

[0012] In some embodiments of this application, the stator module has a first communication receiving end, a first communication transmitting end, a second communication receiving end, and a second communication transmitting end; the controller has a third communication receiving end, a third communication transmitting end, a fourth communication receiving end, and a fourth communication transmitting end; the two ends of the first sub-cable are respectively connected to the first communication transmitting end of the stator module and the first communication receiving end of an adjacent stator module; the two ends of the second sub-cable are respectively connected to the third communication transmitting end of the controller and the first communication receiving end of the stator module, and / or, the two ends of the second sub-cable are respectively connected to the first communication transmitting end of the stator module and the third communication receiving end of the controller.

[0013] When the controller's third communication transmitter and the stator module's first communication receiver are connected at both ends of the second sub-cable, control commands issued by the controller are transmitted through the third communication transmitter and then transmitted to the stator module via the second sub-cable. The stator module then transmits the control commands to the adjacent stator module via the first communication transmitter, the first sub-cable, and the first communication receiver of the adjacent stator module. When the controller's third communication receiver is connected at both ends of the second sub-cable, the controller can receive feedback signals from the stator module via the second sub-cable to obtain the current status information of the stator module. When the controller's third communication transmitter and the first communication receiver of one stator module are connected at both ends of one second sub-cable, and the first communication transmitter and the third communication receiver of another stator module are connected at both ends of the other second sub-cable, the controller can not only issue control commands to the stator module via the second sub-cable but also receive feedback signals from the stator module via the second sub-cable.

[0014] In some embodiments of this application, the two ends of the third sub-cable are respectively connected to the second communication transmitter of the stator module and the second communication receiver of the adjacent stator module; the two ends of the fourth sub-cable are respectively connected to the fourth communication transmitter of the controller and the second communication receiver of the stator module, and / or, the two ends of the fourth sub-cable are respectively connected to the second communication transmitter of the stator module and the fourth communication receiver of the controller.

[0015] When the controller's fourth communication transmitter and the stator module's second communication receiver are connected at both ends of the fourth sub-cable, control commands issued by the controller are transmitted through the fourth communication transmitter and then transmitted to the stator module via the fourth sub-cable. The stator module then transmits the control commands to the adjacent stator module via the second communication transmitter, the third sub-cable, and the second communication receiver of the adjacent stator module. When the controller's fourth communication receiver is connected at both ends of the fourth sub-cable, the controller can receive feedback signals from the stator module via the fourth sub-cable to obtain the current status information of the stator module. When the controller's fourth communication transmitter and the second communication receiver of one stator module are connected at both ends of one fourth sub-cable, and the controller's fourth communication receiver is connected at both ends of another stator module, the controller can not only issue control commands via the fourth sub-cable but also receive feedback signals from the stator module via the fourth sub-cable.

[0016] In some embodiments of this application, the stator module further includes a fault detection module, which is used to detect the continuity of the first sub-cable, the second sub-cable, the third sub-cable, and the fourth sub-cable.

[0017] When the fault detection module detects a fault in the corresponding cable, it can issue a warning signal, such as an audible signal or a visual signal, to alert the user so that the user can intervene in a timely manner and troubleshoot the fault.

[0018] In some embodiments of this application, the magnetic drive conveying system further includes a main power supply and a redundant power supply. The main power supply forms a first current loop that flows through the controller or the stator module. The redundant power supply forms a second current loop that flows through the controller or the stator module.

[0019] By using a main power supply and a redundant power supply, it's beneficial to prevent the magnetic drive conveyor system from malfunctioning due to power supply failures. When the main power supply fails, the redundant power supply can still power the stator module and controller to ensure the magnetic drive conveyor system operates normally; conversely, when the redundant power supply fails, the main power supply can still power the stator module and controller to ensure the magnetic drive conveyor system operates normally. This way, when repairing a faulty power supply, the magnetic drive conveyor system can maintain normal operation without needing to be shut down.

[0020] In some embodiments of this application, the magnetic drive conveying system further includes a mover, which is slidably connected to the stator module; the magnetic field generated by the mover interacts with the magnetic field generated by the stator module to drive the mover to move.

[0021] Therefore, by utilizing the movement of the mover, material can be transported. For example, multiple stator modules can be arranged in a preset manner to define the movement trajectory of the mover. As the mover moves along the trajectory, the material can be transported to the target location.

[0022] In some embodiments of this application, the stator module is a connecting stator module, the connecting stator module includes the first switch module and / or the controller includes the second switch module, and the main cable and the redundant cable connect the connecting stator module and the controller.

[0023] In this embodiment, the magnetic drive conveyor system includes a main cable and a redundant cable between the stator module and the controller. This configuration ensures that if one cable between the controller and the stator module fails, the other cable can still transmit signals normally, guaranteeing interaction between the controller and the stator module. This reduces the impact of cable failures between the controller and the stator module on the magnetic drive conveyor system.

[0024] In some embodiments of this application, the stator module includes: a linear stator module; a connecting stator module, which is connected to the linear stator module via the cable group; the linear stator module includes a first switch module and / or the controller includes a second switch module, and the main cable and the redundant cable connect the linear stator module and the controller.

[0025] In this embodiment, the magnetic drive conveyor system includes a main cable and a redundant cable between the linear stator module and the controller. This configuration ensures that if one cable between the controller and the linear stator module fails, the other cable can still transmit signals normally, guaranteeing that the controller can interact with the linear stator module. This reduces the impact of cable failures between the controller and the linear stator module on the magnetic drive conveyor system. Attached Figure Description

Detailed Implementation

[0038] To make the objectives, technical solutions, and advantages of this application clearer, the following detailed description is provided in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative and not intended to limit the scope of this application.

[0039] This application provides a magnetic drive conveyor system that can reduce the impact of cable faults between the controller and the conveyor line on the magnetic drive conveyor system.

[0040] Please refer to Figures 1 to 5 As shown in the figure, this application embodiment provides a magnetic drive conveying system, which includes a stator module 10, a controller 20, and a cable group. The cable group connects at least the stator module 10 and the controller 20 to enable conduction between the stator module 10 and the controller 20. The cable group includes a main cable 31 and a redundant cable 32. The stator module 10 includes a first switch module 11, which is used to select the main cable 31 and the redundant cable 32. And / or, the controller 20 includes a second switch module 21, which is used to select the main cable 31 and the redundant cable 32.

[0041] Specifically, the conveyor line of the magnetic drive conveyor system is mainly composed of multiple stator modules 10, which can be arranged in a preset direction to construct the running trajectory of the mover.

[0042] The controller 20 is used to send control commands to the stator module 10, such as commands to control whether the stator module 10 is energized. In some cases, the controller 20 is also used to receive feedback signals from the stator module 10, so that the controller 20 can adjust the control commands in real time according to the current state information fed back by the stator module 10, thereby forming a closed-loop control.

[0043] The cable group connects at least the stator module 10 and the controller 20. The cable group includes a main cable 31 and a redundant cable 32. The main cable 31 connects the controller 20 to all stator modules 10, enabling information transmission between the controller 20 and the stator modules 10 in the magnetic drive conveyor system, ensuring the integrity of information transmission. The redundant cable 32 connects stator modules 10 to each other, or between the controller 20 and the stator modules 10. It is understood that when a portion of the main cable 31 (such as the main cable 31 between two adjacent stator modules 10, or the main cable 31 between the stator module 10 and the controller 20) experiences a fault such as breakage or damage, the redundant cable 32 remains conductive to maintain information transmission between the stator modules 10 and the controller 20, thus ensuring the normal operation of the magnetic drive conveyor system. Even when replacing or repairing the main cable 31, the magnetic drive conveyor system can still maintain normal operation, avoiding time wasted due to system downtime caused by maintenance. The cable group in this embodiment is used to realize information transmission between the stator module 10 and the controller 20. This embodiment does not limit the specific type of the cable group. For example, the cable group can be an optical fiber, a data cable, etc.

[0044] The following example illustrates the connection relationship between the main cable 31 and the redundant cable 32:

[0045] In some embodiments, reference Figures 1 to 4 The main cable 31 includes both the portion connecting the stator module 10 and the controller 20 (the second sub-cable 312 mentioned below) and the portion connecting two adjacent stator modules 10 (the first sub-cable 311 mentioned below); the redundant cable 32 includes both the portion connecting the stator module 10 and the controller 20 (the fourth sub-cable 322 mentioned below) and the portion connecting two adjacent stator modules 10 (the third sub-cable 321 mentioned below).

[0046] Additionally, when the controller 20 is connected in series with the stator module 10, the redundant cable 32 can be installed only between the controller 20 and one of the stator modules 10 (see reference). Figure 4 It can also be set between the controller 20 and the two stator modules 10 simultaneously (see reference). Figure 1 ).

[0047] In another example, refer to Figure 2 , Figure 3 The main cable 31 includes both the part connecting the stator module 10 and the controller 20 (i.e., the second sub-cable 312) and the part connecting two adjacent stator modules 10 (the first sub-cable 311 mentioned below). The redundant cable 32 may only include the part connecting the stator module 10 and the controller 20 (i.e., the fourth sub-cable 322).

[0048] Additionally, when the controller 20 is connected in series with the stator module 10, the redundant cable 32 can be installed only between the controller 20 and one of the stator modules 10 (see reference). Figure 3 It can also be set between the controller 20 and the two stator modules 10 simultaneously (see reference). Figure 2 The stator module 10 includes a first switch module 11, and / or the controller 20 includes a second switch module 21. That is, a switch module for selecting the main cable 31 and the redundant cable 32 can be located in the stator module 10 (see reference). Figure 5 It can also be set in controller 20 (see reference). Figure 1 Alternatively, both the stator module 10 and the controller 20 are equipped with a switch module for selecting the main cable 31 and the redundant cable 32.

[0049] The first switch module 11 and the second switch module 21 can be either mechanical switches or analog switches. A mechanical switch is a switching device that uses mechanical operation to open or close a circuit. An analog switch is an electronic component based on analog circuit principles, controlling the on / off state and connection of analog signals by changing its internal resistance or conduction state. Analog switches can be implemented using components such as transistors and MOSFETs (metal-oxide-semiconductor field-effect transistors).

[0050] In the magnetic drive conveying system of this embodiment, the cable group connects at least the stator module 10 and the controller 20. The cable group includes a main cable 31 and redundant cables 32. The main cable 31 connects the controller 20 to all stator modules 10, enabling information transmission between the controller 20 and the stator modules 10 in the magnetic drive conveying system, ensuring the integrity of information transmission. The redundant cables 32 connect stator modules 10 to each other or between the controller 20 and the stator modules 10. Furthermore, at least one of the stator modules 10 and the controller 20 is equipped with a switch module for selecting between the main cable 31 and the redundant cables 32. With this configuration, when the main cable 31 between the controller 20 and the stator modules 10 fails, the switch module can disconnect the faulty cable while simultaneously selecting the redundant cables 32 to ensure information transmission between the stator modules 10 and the controller 20, thus maintaining the normal operation of the magnetic drive conveying system and preventing downtime due to a main cable 31 failure. Furthermore, since the switch module selects the redundant cable 32 and disconnects the faulty main cable 31, the faulty cable can be repaired while ensuring that the magnetic drive conveyor system can still operate normally without shutdown. This avoids the problem of reduced process efficiency due to maintenance time and reduces wasted time. Therefore, the solution in this application can reduce the impact of cable faults between the controller 20 and the conveyor line on the magnetic drive conveyor system.

[0051] In some embodiments of this application, when the stator module 10 includes a first switch module 11, the first switch module 11 has a first position and a second position. When the first switch module 11 is in the first position, the main cable 31 is turned on, and when the first switch module 11 is in the second position, the redundant cable 32 is turned on.

[0052] For example, the first switch module 11 is a mechanical switch with multiple contacts. The actuator (e.g., excitation coil), main cable 31, and redundant cable 32 in the stator module 10 are each connected to a corresponding contact. By adjusting the position of the switch conductive element, the first switch module 11 can activate the corresponding contact, thereby enabling selective activation of the actuator with either the main cable 31 or the redundant cable 32. For example, when the switch conductive element is in the first position, the actuator is activated with the main cable 31, and the controller 20 and the stator module 10 transmit signals through the main cable 31. When the switch conductive element of the first switch module 11 is in the second position, the actuator is activated with the redundant cable 32, and the controller 20 and the stator module 10 transmit signals through the redundant cable 32. In some embodiments, the first switch module 11 is in a first position to enable the main cable 31 to conduct. When the stator module 10 sends information to the controller 20 (i.e., the stator module 10 acts as the transmitter and the controller 20 acts as the receiver), if the information sent by the stator module 10 cannot be received by the controller 20, the main cable 31 may be damaged. In this case, the first switch module 11 switches from the first position to the second position to enable the redundant cable 32, thereby achieving signal transmission. Similarly, when one of two adjacent stator modules 10 sends information to the other but the other cannot receive it, the stator module 10 sending the information switches the first switch module 11 from the first position to the second position to enable the redundant cable 32 and achieve information transmission.

[0053] In some embodiments of this application, when the controller 20 includes a second switch module 21, the second switch module 21 has a third position and a fourth position. When the second switch module 21 is in the third position, the main cable 31 is connected, and when the second switch module 21 is in the fourth position, the redundant cable 32 is connected.

[0054] For example, the second switch module 21 is a mechanical switch with multiple contacts. The control unit, main cable 31, and redundant cable 32 in the controller 20 are each connected to a corresponding contact. By adjusting the position of the switch conductive element, the second switch module 21 can activate the corresponding contact, thereby enabling selective activation of the control unit with either the main cable 31 or the redundant cable 32. For instance, when the switch conductive element of the second switch module 21 is in the third position, the control unit is activated with the main cable 31, and the controller 20 transmits signals to the stator module 10 via the main cable 31. When the switch conductive element of the second switch module 21 is in the fourth position, the control unit is activated with the redundant cable, and the controller 20 transmits signals to the stator module 10 via the redundant cable 32. In some embodiments, the second switch module 21 is in the third position to enable the main cable 31 to conduct. When the controller 20 sends information to the stator module 10, that is, the controller 20 acts as the transmitter and the stator module 10 acts as the receiver, if the information sent by the controller 20 cannot be received by the stator module 10, the main cable 31 may be damaged. At this time, the second switch module 21 switches from the third position to the fourth position to enable the redundant cable 32 to conduct, thereby realizing signal transmission.

[0055] Please refer to Figure 1 , Figure 2 As shown, in some embodiments of this application, the main cable 31 and the redundant cable 32 are connected in series between the stator module 10 and the controller 20. The main cable 31 includes a first sub-cable 311 and a second sub-cable 312. The first sub-cable 311 is used to connect two adjacent stator modules 10, and the second sub-cable 312 is used to connect the stator module 10 and the controller 20. The redundant cable 32 includes a third sub-cable 321 and a fourth sub-cable 322. The third sub-cable 321 is used to connect two adjacent stator modules 10, and the fourth sub-cable 322 is used to connect the stator module 10 and the controller 20.

[0056] Typically, the conveyor line includes multiple stator modules 10. Different stator modules 10 need to exchange information; for example, commands issued by the controller 20 need to be transmitted to each stator module via cable groups. Based on these usage requirements, the main cable 31 includes a first sub-cable 311 and a second sub-cable 312. The first sub-cable 311 connects two adjacent stator modules 10, and the second sub-cable 312 connects the stator module 10 to the controller 20. In some embodiments, when there are multiple stator modules 10, the number of first sub-cables 311 can be multiple, with each pair of adjacent stator modules 10 connected by a first sub-cable 311.

[0057] Similarly, the redundant cable 32 includes a third sub-cable 321 and a fourth sub-cable 322. The third sub-cable 321 is used to connect two adjacent stator modules 10, and the fourth sub-cable 322 is used to connect the stator module 10 and the controller 20. In some embodiments, when there are multiple stator modules 10, the number of third sub-cables 321 can be multiple, and each pair of adjacent stator modules 10 is connected through a third sub-cable 321.

[0058] In some embodiments of this application, a single controller 20 is capable of both issuing control commands and receiving feedback signals from the stator module 10. Please refer to [reference needed]. Figure 2 , Figure 3 The number of second sub-cables 312 can be two, and the number of fourth sub-cables 322 can be one (a fourth sub-cable 322 is provided between the controller 20 and one of the stator modules 10) or two (a fourth sub-cable 322 is provided between the controller 20 and both stator modules 10).

[0059] Please refer to Figure 1 As shown, in some embodiments of this application, the stator module 10 has a first communication receiver V1, a first communication transmitter V2, a second communication receiver V3, and a second communication transmitter V4, and the controller 20 has a third communication receiver V5, a third communication transmitter V6, a fourth communication receiver V7, and a fourth communication transmitter V8.

[0060] like Figure 1 As shown, in one embodiment, the two ends of the first sub-cable 311 are respectively connected to the first communication transmitter V2 of the stator module 10 and the first communication receiver V1 of the adjacent stator module 10, the two ends of the second sub-cable 312 are respectively connected to the third communication transmitter V6 of the controller 20 and the first communication receiver V1 of the stator module 10, and / or, the two ends of the second sub-cable 312 are respectively connected to the first communication transmitter V2 of the stator module 10 and the third communication receiver V5 of the controller 20.

[0061] When the third communication transmitter V6 of the controller 20 and the first communication receiver V1 of the stator module 10 are connected at both ends of the second sub-cable 312, the control command issued by the controller 20 is sent through the third communication transmitter V6 and transmitted to the stator module 10 through the second sub-cable 312. The stator module 10 then transmits the control command to the adjacent stator module 10 through the first communication transmitter V2, the first sub-cable 311 and the first communication receiver V1 of the adjacent stator module 10.

[0062] When the first communication transmitter V2 of the stator module 10 and the third communication receiver V5 of the controller 20 are connected at both ends of the second sub-cable 312, the controller 20 can receive feedback signals from the stator module 10 through the second sub-cable 312 to obtain the current status information of the stator module 10.

[0063] When one end of a second sub-cable 312 is connected to the third communication transmitter V6 of the controller 20 and the first communication receiver V1 of one of the stator modules 10, and the other end of a second sub-cable 312 is connected to the first communication transmitter V2 of another stator module 10 and the third communication receiver V5 of the controller 20, the controller 20 can not only send control commands to the stator module 10 through the second sub-cable 312, but also receive feedback signals from the stator module 10 through the second sub-cable 312.

[0064] like Figure 1 As shown, in one embodiment, the two ends of the third sub-cable 321 are respectively connected to the second communication transmitter V4 of the stator module 10 and the second communication receiver V3 of the adjacent stator module 10, the two ends of the fourth sub-cable 322 are respectively connected to the fourth communication transmitter V8 of the controller 20 and the second communication receiver V3 of the stator module 10, and / or, the two ends of the fourth sub-cable 322 are respectively connected to the second communication transmitter V4 of the stator module 10 and the fourth communication receiver V7 of the controller 20.

[0065] When the fourth communication transmitter V8 of the controller 20 and the second communication receiver V3 of the stator module 10 are connected at both ends of the fourth sub-cable 322, the control command issued by the controller 20 is sent through the fourth communication transmitter V8 and transmitted to the stator module 10 through the fourth sub-cable 322. The stator module 10 then transmits the control command to the adjacent stator module 10 through the second communication transmitter V4, the third sub-cable 321 and the second communication receiver V3 of the adjacent stator module 10.

[0066] When the second communication transmitter V4 of the stator module 10 and the fourth communication receiver V7 of the controller 20 are connected at both ends of the fourth sub-cable 322, the controller 20 can receive feedback signals from the stator module 10 through the fourth sub-cable 322 to obtain the current status information of the stator module 10.

[0067] When one end of a fourth sub-cable 322 is connected to the fourth communication transmitter V8 of the controller 20 and the second communication receiver V3 of one of the stator modules 10, and the other end of a fourth sub-cable 322 is connected to the second communication transmitter V4 of another stator module 10 and the fourth communication receiver V7 of the controller 20, the controller 20 can not only send control commands through the fourth sub-cable 322, but also receive feedback signals from the stator module 10 through the fourth sub-cable 322.

[0068] In some embodiments of this application, the stator module 10 further includes a fault detection module, which is used to detect the continuity of the first sub-cable 311, the second sub-cable 312, the third sub-cable 321, and the fourth sub-cable 322.

[0069] When the fault detection module detects a fault in the corresponding cable, the first switch module 11 or the second switch module 21 can automatically switch positions to ensure the normal operation of the magnetic drive conveyor system. Furthermore, the fault detection module can issue warning signals, such as audible or visual signals, to alert the user and allow for timely intervention and troubleshooting.

[0070] The fault detection module can also be electrically connected to the controller 20. The controller 20 can be configured to control the first switch module to select the main cable 31 and the redundant cable 32 based on the detection results of the fault detection module. Thus, when a fault is detected in the first sub-cable 311 and / or the second sub-cable 312, the redundant cable 32 can be selected; when a fault is detected in the third sub-cable 321 and / or the fourth sub-cable 322, the main cable 31 can be selected. This ensures that the magnetic drive conveyor system operates normally without being affected by cable faults.

[0071] Furthermore, the fault detection module can be a current detection sensor. The current detection sensor can determine whether the first sub-cable 311, second sub-cable 312, third sub-cable 321, and fourth sub-cable 322 are in normal or abnormal condition based on the magnitude of the current. When any cable exhibits an abnormal state, a fault can be identified. Specifically, there can be multiple fault detection modules, with each of the first sub-cable 311, second sub-cable 312, third sub-cable 321, and fourth sub-cable 322 equipped with a current detection sensor. This allows for comprehensive fault detection across all sub-cables.

[0072] Please refer to Figure 6As shown, in some embodiments of this application, the magnetic drive conveying system further includes a power supply unit 40. The power supply unit 40 is electrically connected to the controller 20 and the stator module 10 via a cable 41 to supply power to the controller 20 and the stator module 10. In some embodiments, the power supply unit 40 includes a main power supply 401 and a redundant power supply 402. The main power supply 401 forms a first current loop that flows through the controller 20 and the stator module 10, and the redundant power supply 402 forms a second current loop that flows through the controller 20 and the stator module 10.

[0073] The main power supply 401 and the redundant power supply 402 can simultaneously power the stator module 10 and the controller 20, or they can power the stator module 10 and the controller 20 individually. By using the main power supply 401 and the redundant power supply 402, it is also beneficial to avoid the magnetic drive conveyor system malfunctioning due to power supply failure. That is, when the main power supply 401 fails, the redundant power supply 402 can still power the stator module 10 and the controller 20 to ensure the normal operation of the magnetic drive conveyor system; conversely, when the redundant power supply 402 fails, the main power supply 401 can still power the stator module 10 and the controller 20 to ensure the normal operation of the magnetic drive conveyor system. Thus, when repairing a faulty power supply, the magnetic drive conveyor system can maintain normal operation without needing to stop running.

[0074] In one embodiment, a third switch module is provided between the main power supply 401, the redundant power supply 402 and the controller 20. The third switch module has a fifth position and a sixth position. When the third switch module is in the fifth position, it connects the main power supply 401 and the controller 20. When the third switch is in the sixth position, it connects the redundant power supply 402 and the controller 20.

[0075] In one embodiment, a third switch module is provided between the main power supply 401, the redundant power supply 402 and the stator module 10. The third switch module has a fifth position and a sixth position. When the third switch module is in the fifth position, it connects the main power supply 401 and the stator module 10. When the third switch is in the sixth position, it connects the redundant power supply 402 and the stator module 10.

[0076] In one embodiment, a first on / off switch is provided between one of the controller 20 and the stator module 10 and the main power supply 401, and a second on / off switch is provided between the other of the controller 20 and the stator module 10 and the redundant power supply 402. By controlling the first and second on / off switches, the main power supply 401 and the redundant power supply 402 can be powered on or off.

[0077] In some embodiments of this application, the magnetic drive conveying system further includes a mover (not shown in the figure), which is slidably connected to the stator module 10. The magnetic field generated by the mover interacts with the magnetic field generated by the stator module 10, thereby driving the mover to move. Thus, the movement of the mover can be used to convey materials. For example, multiple stator modules 10 can be arranged in a preset manner to define the movement trajectory of the mover. As the mover moves along the movement trajectory, the material can be conveyed to the target position.

[0078] like Figure 7 As shown, in some embodiments of this application, the stator module 10 is connected to the stator module 10b. That is, in this embodiment, the connected stator module 10b includes a first switch module 11 and / or the controller 20 includes a second switch module 21, and the main cable 31 and the redundant cable 32 connect the connected stator module 10b and the controller 20.

[0079] It is understandable that the connecting stator module 10b moves back and forth in a certain direction to connect with different conductors, thereby realizing the transport of the mover across conductors. Since the movement of the connecting stator module 10b may cause cable damage during its movement, the magnetic drive transport system in this embodiment provides a main cable 31 and a redundant cable 32 between the connecting stator module 10b and the controller 20. This configuration ensures that if one cable between the controller 20 and the connecting stator module 10b fails, the other cable can still transmit signals normally, guaranteeing that the controller 20 can interact with the connecting stator module 10b. This reduces the impact of cable failures between the controller 20 and the connecting stator module 10b on the magnetic drive transport system. It should be noted that in this embodiment, one end of the controller 20 is connected to the connecting stator module 10b to better control the connecting stator module 10b.

[0080] like Figure 8 As shown, in some embodiments of this application, the stator module 10 includes a linear stator module 10a and a connecting stator module 10b, which are connected to the linear stator module 10a via a cable assembly. The linear stator module 10a includes a first switch module 11 and / or the controller 20 includes a second switch module 21. A main cable 31 and a redundant cable 32 connect the linear stator module 10a and the controller 20.

[0081] Linear stator module 10a refers to a stator module that guides the mover to move along a straight path. Multiple linear stator modules 10a can be arranged to form a conveyor line.

[0082] The connecting stator module 10b refers to a stator module capable of carrying a mover and transferring the mover between different conveyor lines. The connecting stator module 10b moves back and forth in a certain direction to connect with different lines, thereby realizing the transport of the mover across the lines.

[0083] In this embodiment, the magnetic drive conveying system includes a main cable 31 and a redundant cable 32 between the linear stator module 10a and the controller 20. This configuration ensures that if one cable between the controller 20 and the linear stator module 10a fails, the other cable can still transmit signals normally, guaranteeing that the controller 20 can interact with the linear stator module 10a. This reduces the impact of cable failures between the controller 20 and the linear stator module 10a on the magnetic drive conveying system.
