Detailed Implementation

[0036] 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. In the description of this application, "multiple" means at least two, such as two, three, etc., unless otherwise explicitly specified.

[0037] In this application, unless otherwise expressly specified and limited, the terms "connection," "fixed," etc., should be interpreted broadly. For example, "connection" can be a fixed connection, a detachable connection, or an integral part; it can be a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium; it can be the internal communication of two components or the interaction between two components, unless otherwise expressly limited. Those skilled in the art can understand the specific meaning of the above terms in this application according to the specific circumstances.

[0038] In the process of creating this application, it was found that current conveyor lines composed of stator modules and mover modules generally achieve a movable connection between the mover module and the stator module by having the mover module straddle the base of the stator module. This arrangement requires the mover module to be larger than the base of the stator module, and clearance must be left for installation and mating. This results in a large mating dimension between the mover module and the stator module, which is detrimental to the miniaturization and flexibility of the conveyor line. At the same time, current stator modules do not consider ventilation and cooling for the electronic components mounted on the base, making it difficult to effectively cool the existing stator modules, affecting the use of the electronic components, causing heat loss, and thus reducing the service life of the stator module. To solve the problems of insufficient heat dissipation and large mating dimensions of stator modules in related technologies, this application proposes a stator module and a conveyor line.

[0039] Please refer to Figures 1 to 3. The stator module 100 in this embodiment includes a base 1, an armature winding 2, and a circuit board 3.

[0040] The base 1 and armature winding 2 both extend along a first direction A. The armature winding 2 is connected to the base 1 and at least partially protrudes from the base 1 along a second direction B, which intersects with the first direction A. A heat dissipation channel 11 is formed inside the base 1, and a vent 12 communicating with the heat dissipation channel 11 is formed on the base 1. The circuit board 3 is located inside the heat dissipation channel 11 and is electrically connected to the armature winding 2.

[0041] In the above structure, the base 1 is used to support the armature winding 2 and the circuit board 3. The circuit board 3 and the armature winding 2 are electrically connected. The circuit board 3 is used to control the periodic energization of the armature winding 2 so that the armature winding 2 generates a changing magnetic field. In the embodiments of this application, the armature winding 2 is used to match the mover module 200. Therefore, the changing magnetic field is used to magnetically cooperate with the permanent magnet array on the mover module 200 and realize the driving of the mover module 200.

[0042] It is understood that the first direction A mentioned above corresponds to the conveying direction of the stator module 100, that is, the direction in which the stator module 100 conveys the mover module 200. By connecting the armature winding 2 to the base 1 and at least partially protruding from the base 1 along the second direction B intersecting with the first direction A, it is convenient for the mover module 200 to be directly matched and installed with the armature winding 2. This means that the mover module 200 does not need to be installed with the entire base 1, but only with the armature winding 2, thereby reducing the overall fit size between the mover module 200 and the base 1. At the same time, since a heat dissipation channel 11 is formed inside the base 1, and a vent 12 communicating with the heat dissipation channel 11 is formed on the base 1, the heat dissipation channel 11 is connected to the outside, which facilitates heat dissipation for the circuit board 3 located in the heat dissipation channel 11, solving the problem of slow heat dissipation of the stator module 100.

[0043] Furthermore, the base 1 includes a first base body 13 and a second base body 14, with the armature winding 2 connected to the first base body 13; the second base body 14 is located below the first base body 13 and connected to the first base body 13, the second base body 14 protrudes relative to the first base body 13, and the second base body 14 and the armature winding 2 protrude from the same side of the first base body 13; heat dissipation channels 11 are provided on the first base body 13 and / or the second base body 14, and ventilation openings 12 are provided on the first base body 13 and / or the second base body 14.

[0044] It is understood that the base 1 has a first base body 13 and a second base body 14 arranged sequentially in the vertical direction. The second base body 14 protrudes from one side relative to the first base body 13, and the protruding side of the second base body 14 is the same side as the protruding side of the armature winding 2 installed to the first base body 13. Therefore, an installation space is formed between the two protrusions of the second base body 14 and the armature winding 2, which facilitates the assembly of the mover module 200 and the armature winding 2. At this time, the mover module 200 is installed along one side of the base 1 without having to span to both sides of the base 1, thereby better reducing the installation size of the base 1 and the mover module 200, so as to achieve the purpose of miniaturization of the stator module 100 and the mover module 200.

[0045] To further enhance heat dissipation, the stator module 100 also includes a fan (not shown in the figure). The fan is located within the heat dissipation channel 11. Multiple vents 12 are formed on the base 1, including air inlets 121 and exhaust outlets 122. The fan directs airflow into the heat dissipation channel 11 through the air inlets 121 and exhausts it through the exhaust outlets 122. Thus, when the fan is located within the heat dissipation channel 11, its operation accelerates the airflow within the channel, allowing low-temperature air from the environment to enter through the air inlets 121, thereby dissipating heat from the electronic components inside the channel. The heated air is then exhausted through the exhaust outlets 122. This cycle effectively enhances the heat dissipation effect within the channel 11, cooling the circuit board 3 and providing a suitable temperature environment for its operation. In the embodiments of this application, the type of fan is not limited; it can be a centrifugal fan or an axial fan, as long as it achieves the desired airflow effect.

[0046] Furthermore, the shape of the air inlet 121 can be varied, including circular, rectangular, or other special shapes. In the embodiments of this application, the air inlet 121 includes multiple grids arranged sequentially, which provides a larger ventilation area, facilitates manufacturing and installation, and allows the size and number of grids to be adjusted as needed to adapt to different equipment requirements and achieve the corresponding heat dissipation effect.

[0047] In some embodiments, the circuit board 3 is located downstream of the fan along the airflow direction. It is worth noting that the airflow direction refers to the direction in which air flows in from the air inlet 121, is driven by the fan to flow through the heat dissipation channel 11, and then flows out along the exhaust port 122. Therefore, when the circuit board 3 is located downstream of the fan, the low-temperature air flowing in from the outside is driven by the fan, and the flow speed is accelerated. The high-speed flowing gas can carry away the heat in the heat dissipation channel 11, thereby effectively cooling the circuit board 3.

[0048] To further enhance the heat dissipation effect of the fan on the circuit board 3, the fan has an air inlet and an air outlet. Along the airflow direction, the air inlet is located downstream of the air inlet 121, and the air outlet is also downstream of the air inlet. The circuit board 3 is located downstream of the air outlet, with its surface facing the air outlet. It is understood that the circuit board 3 is typically a thin plate structure, and the surface of the circuit board 3 can specifically refer to the surface on the circuit board 3 used to place circuit components or the surface opposite to the placement of circuit components. Since the surface on the circuit board 3 used to place circuit components or the surface opposite to the placement of circuit components has a larger surface area than the remaining surface area, designing the surface of the circuit board 3 to face the air outlet increases the surface area of ​​the circuit board 3 directly opposite the fan's air outlet, thereby improving the heat dissipation effect of the circuit board 3.

[0049] Furthermore, the fan's outlet can be positioned directly facing the surface of the circuit board 3 where circuit components are placed. In this way, the low-temperature airflow flowing in from the inlet 121 enters along the fan's inlet and flows out from the fan's outlet after being accelerated by the fan. During this process, the accelerated flow of low-temperature airflow can directly contact the circuit components and exchange heat with the surface of the circuit board 3 more quickly, thereby reducing the temperature of the surface of the circuit board 3 and achieving a better heat dissipation effect.

[0050] Referring to Figure 2, the base 1 has a bottom surface 1a and a first side surface 1b connected to the bottom surface 1a. Both the bottom surface 1a and the first side surface 1b extend along a first direction A. An air inlet 121 is disposed on the bottom surface 1a and / or the first side surface 1b. In the embodiments of this application, the number of air inlets 121 is not limited; it can be single or multiple. A single air inlet 121 is located on either the bottom surface 1a or the first side surface 1b of the base 1. Multiple air inlets 121 can be disposed on the bottom surface 1a and the first side surface 1b of the base 1, respectively. Different settings of the number and position of the air inlets 121 result in different placement positions of the circuit board 3 and the fan. For example, when a single air inlet 121 is located on the bottom surface 1a of the base 1, the fan is positioned close to the bottom surface 1a of the base 1, and the circuit board 3... The air inlet 121 is located near the bottom surface 1a of the base 1, downstream of the fan along the airflow direction. When a single air inlet 121 is located on the first side surface 1b of the base 1, with the fan positioned close to the first side surface 1b and the circuit board 3 also located near the first side surface 1b of the base 1, downstream of the fan along the airflow direction, the number of air inlets 121 increases, allowing for more effective airflow entry and heat exchange with the interior of the base 1, resulting in superior cooling performance. Therefore, the position and number of air inlets 121 can be flexibly set according to actual needs to adapt to different application scenarios. The placement of the circuit board 3 and the fan is variable, providing space for the arrangement of other components inside the base 1 and facilitating efficient use of space within the base 1.

[0051] Based on this, the base 1 also has a second side 1c connected to the bottom surface 1a. The first side 1b and the second side 1c are located on opposite sides of the base 1 along the second direction B, and the second side 1c extends along the first direction A. The exhaust port 122 is disposed on the first side 1b and / or the second side 1c. It can be understood that the ventilation port 12 also includes an exhaust port 122. The air inlet 121 and the exhaust port 122 are connected through the heat dissipation channel 11, so as to realize the effect of air being introduced into the air inlet 121 and air being discharged from the exhaust port 122, forming a unidirectional airflow within the base 1. This facilitates the guidance of airflow, allowing the airflow to cool the devices located within the heat dissipation channel 11 according to the set heat dissipation channel 11.

[0052] Referring to Figure 1, to achieve better ventilation, the exhaust port 122 extends along the first direction A and penetrates the base 1. In the embodiment of this application, the exhaust port 122 penetrates the base 1 to communicate with the heat dissipation channel 11, and the exhaust port 122 extends along the first direction A to form a larger air guiding area, so that the airflow in the base 1 can be discharged through the exhaust port 122 to achieve a better ventilation effect.

[0053] Based on the above embodiments, the armature winding 2 is positioned corresponding to the exhaust port 122, and at least a portion of the armature winding 2 is located downstream of the exhaust port 122 along the airflow direction. It is understood that during the operation of the stator module 100, the armature winding 2 generates current, and the thermal effect of this current causes the temperature of some components of the armature winding 2 to rise, thus adversely affecting the operation of the armature winding 2. In this embodiment, the armature winding 2 is positioned corresponding to the exhaust port 122. Therefore, the low-temperature air entering from the air inlet 121 can pass through the heat dissipation channel 11, be driven by the fan, and then be discharged from the exhaust port 122 via the heat dissipation channel 11, thus blowing air to cool the corresponding armature winding 2, removing the heat from the armature winding 2, achieving a cooling effect on the armature winding 2, and thereby avoiding the adverse effects of the current thermal effect within the armature winding 2.

[0054] Further, referring to Figure 1, a portion of the armature winding 2 passes through the exhaust port 122 and is located within the heat dissipation channel 11. It is understood that the extension of a portion of the armature winding 2 into the heat dissipation channel 11 increases the contact area between the armature winding 2 and the heat dissipation channel 11, thereby increasing the contact area between the armature winding 2 and the flowing air, achieving better heat dissipation, and effectively reducing the heat on the surface of the armature winding 2.

[0055] Furthermore, referring to Figure 3, in the embodiments of this application, the heat dissipation channel 11 can be set in various ways. The form of the heat dissipation channel 11 can be flexibly set according to needs. For example, when the heat dissipation channel 11 is located in the first base 13, the air inlet 121 is located on the first side 1b, and the exhaust outlet 122 is located on the second side 1c. In this case, the circuit board 3 is vertically arranged in the heat dissipation channel 11 within the first base 13, and the fan is located between the air inlet 121 and the circuit board 3. The airflow flows sequentially through the air inlet 121, the fan, the circuit board 3, the exhaust outlet 122, and the armature winding 2, achieving cooling and heat dissipation for the circuit board 3 and the armature winding 2. Furthermore, since the circuit board 3 is placed vertically, it does not increase the lateral space of the base 1, facilitating the assembly of the armature winding 2 and the mover module 200, reducing the lateral dimensions of their assembly, so as to achieve the desired effect for the stator module 100 and the mover module 200. For example, when the heat dissipation channel 11 is located inside the second base 14, the air inlet 121 is located on the bottom surface 1a of the base 1, and the exhaust outlet 122 is located on the second side surface 1c, the heat dissipation channel 11 is also connected to the first base 13 to achieve the connection between the air inlet 121 and the exhaust outlet 122. The circuit board 3 is placed horizontally in the second base 14, and the fan is located between the air inlet 121 and the circuit board 3. The airflow flows through the air inlet 121, the fan, the circuit board 3, the exhaust outlet 122, the armature winding 2 and other devices in sequence, which can achieve the cooling and heat dissipation of the circuit board 3 and the armature winding 2. Furthermore, the circuit board 3 is placed horizontally inside the second base 14, which will not affect the matching of the mover module 200 and the armature winding 2. Since the length of the heat dissipation channel 11 is longer at this time, the airflow can pass through various components inside the base 1 to dissipate heat and cool down each component, thus its heat dissipation effect is better.

[0056] Referring to Figure 4, the base 1 also includes a guide rail 15. The guide rail 15 extends along the first direction A of the stator module 100 and is mounted above the second base 14. The armature winding 2 is located above the guide rail 15 and spaced apart from it. In actual installation, one side of the mover module 200 is open to match the armature winding 2. The bottom of the mover module 200 has rollers that match the guide rail 15 on the base 1, facilitating the sliding of the mover module 200 along the guide rail 15 on the base 1. This provides a more precise guiding effect and also facilitates the movement of the mover module 200.

[0057] Referring to Figures 1, 3, and 4, in some embodiments, the stator module 100 further includes a connector 4 and a cable (not shown). The connector 4 is connected to the base 1; the cable is used for electrical connection with the connector 4. The base 1 has a receiving groove 16 for accommodating the cable, extending along a first direction A of the stator module 100. It is understood that the connector 4 is electrically connected to the circuit board 3, and the base 1 has a hole corresponding to the connector 4, allowing the connector 4 to be exposed at the base 1 for insertion with the cable. Furthermore, the receiving groove 16 at the base 1 can accommodate the cable, facilitating cable retraction and providing protection and a certain aesthetic effect. In addition, the cable includes power lines and signal lines.

[0058] Further, referring to Figures 1 to 5, the base 1 has a bottom surface 1a, a first side surface 1b connected to the bottom surface 1a, and a second side surface 1c opposite to the first side surface 1b along the second direction B. Both the first side surface 1b and the second side surface 1c extend along the first direction A of the stator module 100. Referring to the stator module 100 extending along the arc on the upper side of Figure 4, the first side surface 1b has a socket, and the plug-in 4 is provided corresponding to the socket. The socket is the cavity for the plug-in 4 to communicate with the external space. The plug-in 4 is provided through the socket so that the plug on the plug-in 4 is exposed on the base 1, thereby allowing the plug-in 4 to communicate with external cables through the socket. The plug-in 4 is provided on the side where the first side surface 1b of the base 1 is located, and the receiving groove 16 is provided on the first side surface 1b; or, the second side surface 1c has a socket, and the plug-in 4 is provided corresponding to the socket. The plug-in 4 is provided on the side where the second side surface 1c of the base 1 is located, and the receiving groove 16 is provided on the second side surface 1c. Specifically, the connector 4 and the receiving groove 16 are located on the same side of the base 1. This arrangement facilitates the cable being contained within the receiving groove 16 after it is plugged into the connector 4. On the one hand, since the connector 4 and the receiving groove 16 are located on the first side 1b and / or the second side 1c, which are the two sides connected to the bottom surface 1a, and the first side 1b and the second side 1c extend along the first direction A of the stator module 100, the cable can be directly extended along the first direction A of the stator module 100. The setting of the receiving groove 16 facilitates the cable to be routed along the first direction A of the stator module 100 to connect to the next connector. On the other hand, the receiving groove 16 can form a semi-enclosed state for the cable, thereby providing a certain degree of protection for the cable.

[0059] Furthermore, the stator module 100 also includes a cover 17, which is located on one side of the slot of the receiving groove 16 and covers the slot. The cover 17 is connected to the base 1 and is positioned away from the connector 4. In the embodiments of this application, the cover 17 is detachably installed at the slot of the receiving groove 16. When the cable is being routed and plugged in, the cover 17 is in a detached state, which facilitates the cable routing and plugging. When the cable is plugged in, the cover 17 is in an installed state and covers the slot of the receiving groove 16, which cooperates with the slot of the receiving groove 16 to form a bundle cavity, avoiding the potential hazards of accidental breakage and leakage caused by large areas of exposed cables. It is used to accommodate and protect the cables. From an aesthetic point of view, the cables are covered by the cover 17, which avoids messy cable connection and makes the overall appearance beautiful and pleasing to the eye.

[0060] Referring to Figure 4, the stator module 100 also includes a sensor array 300, which is connected to the first base 13. The first base 13 has a top surface on the side opposite to the second base 14, and the sensor array 300 is located on the top surface, extending along a first direction A. Therefore, in the above structure, the first base 13 is used to support the sensor array 300, and the circuit board 3 is electrically connected to the corresponding sensor array 300. The circuit board 3 reads the position sensed by the sensor array 300 to realize the positioning function of the mover module 200.

[0061] Referring to Figures 4 and 5, the stator module 100 is an arc-shaped stator module 100A, with its first direction A along an arc; or, the stator module 100 is a linear stator module 100B, with its first direction A along a straight line. In practice, the shape of the stator module 100 can be varied. In the technical solution of this application, the stator module 100 is an arc-shaped stator module 100A and / or a linear stator module 100B. The first direction A of the arc-shaped stator module 100A is an arc, thus enabling a reversing function. The first direction A of the linear stator module 100B is a straight line. The arc-shaped stator module 100A and the linear stator module 100B can be installed together. The stator modules 100 of different shapes cooperate to form different conveying states to meet different needs. This application does not limit the combination state of the arc-shaped stator module 100A and the arc-shaped stator module.

[0062] Referring to Figure 4, this application also proposes a conveyor line 1000, which includes a stator module 100. The specific structure of the stator module 100 is as described in the above embodiments. Since the conveyor line 1000 adopts all the technical solutions of all the above embodiments, it has at least all the beneficial effects brought about by the technical solutions of the above embodiments, which will not be repeated here.

[0063] The conveyor line 1000 also includes a mover module 200; the mover module 200 is slidably connected to the base 1 along the first direction A of the stator module 100. The mover module 200 is provided with a permanent magnet array 5, which magnetically engages with the armature winding 2 to drive the mover module 200 to move relative to the stator module 100. This conveyor line 1000 drives the movement of the mover module 200 by employing the magnetic engagement between the permanent magnet array 5 and the armature winding 2. The magnitude of the magnetic force can be controlled by energizing the armature winding 2 and controlling the current with the circuit board 3, thereby precisely controlling the movement of the mover module 200 and enabling the transport and operation of large-capacity, high-efficiency, and long-term round-trip transportation of workpieces or materials.

[0064] In some embodiments, the stator module 100 includes a connector 4 connected to the base 1. In this embodiment, the connector 4 serves to connect to an external power source and / or signal source. The connector 4 may have multiple power interfaces, one of which allows the power cord of an external power source to be plugged in to power the armature winding 2, sensor array 300, and circuit board 3. The other power interfaces allow power cords to be plugged in to connect to the circuit board 3 connected to the connector 4 on adjacent bases 1. When multiple stator modules are provided, since the circuit boards 3 in each stator module are connected in series through the connector 4, only one connector 4 on one base 1 needs to be plugged into an external power source to power all the stator modules 100 as a whole.

[0065] Preferably, the multiple power interfaces can be configured with different voltage levels to adapt to different working environments. For example, the voltage of the external power supply can be changed to generate magnetic fields of different intensities in the armature winding 2. The movement speed of the mover module 200 varies under different magnetic field intensities, thereby controlling the movement speed of the mover module 200. Similarly, the connector 4 can be provided with multiple signal interfaces, one of which is for the signal line of an external signal source to be plugged in, so as to realize signal transmission between the external signal source and the controller or between controllers. Further, the power line can be a cable, wire, etc., and the signal line can be an optical fiber. The power line and signal line can be set separately or combined into a single optical-electric hybrid cable. Correspondingly, the power interface and signal interface can be set separately or combined into a single hybrid interface to realize power supply and signal transmission functions separately or simultaneously.

[0066] The conveyor line 1000 includes multiple stator modules 100, which are connected sequentially. Each stator module 100 includes an arc-shaped stator module 100A and a linear stator module 100B connected to each other. The connector 4 of the arc-shaped stator module 100A is located inside the conveyor line 1000, and the connector 4 of the linear stator module 100B is located outside the conveyor line 1000. Specifically, the multiple stator modules 100 are connected sequentially to form a closed conveyor line 1000, which has corresponding inner and outer sides. The arc-shaped stator module 100A has an arc-shaped base 1, and the linear stator module 100B has a linear base 1. For the arc-shaped base 1, its connector 4 is located inside the conveyor line 1000, and for the linear stator module 100B, its connector 4 is located outside the conveyor line 1000.

[0067] Referring to Figure 4, in some embodiments, when the connector 4 of the arc-shaped base 1 is located inside the arc-shaped base 1, a wire passage 18 is formed on the base 1 of the linear stator module 100B, penetrating the inner and outer sides of the base 1. The connector 4 of the arc-shaped stator module 100A is electrically connected to the connector 4 of the linear stator module 100B after passing through the wire passage 18 with a cable in sequence. The cable passage 18 extends through the linear base 1, and a first cable passage hole 181 and a second cable passage hole 182 are formed on the inner and outer sides of the linear base 1, respectively. One end of the cable is connected to the connector 4 at the arc-shaped base 1, and the other end passes through the first cable passage hole 181, through the cable passage 18, and out through the second cable passage hole 182. It then passes through the receiving groove 16 to the connector 4 at the linear base 1 and connects with the connector 4 at the linear base 1 to form an electrical connection between the arc-shaped base 1 and the linear base 1. The cable passage 18 facilitates cable routing and has a simple circuit without unnecessary winding. The cable does not need to be routed around the top or bottom of the stator module 100 for connection, avoiding the cable from obstructing the movement of the mover module 200 or increasing the risk of collision. On the one hand, it can shorten the cable length and reduce costs; on the other hand, due to the simple circuit, it is easy to achieve quick plugging or disassembly.

[0068] It should be noted that the cross-sectional dimensions of the cable passage 18 should not be designed to be too small or too large. The specific dimensions can be designed according to the number and thickness of the cables to be passed through, as long as the cables can pass through without being excessively bent. Preferably, the cable passage 18 is integrally formed inside the base 1 during the casting process, without the need for subsequent separate excavation or installation, which facilitates the overall manufacturing and installation of the stator module 100.

[0069] In some other embodiments, the connector 4 of the arc-shaped base 1 is located on the outside of the arc-shaped base 1. In this case, there is no need to use the cable passage 18. Instead, after the cable is connected to the connector 4 of the arc-shaped base 1, it is connected to the connector 4 of the straight base 1 along the transport direction of the stator module 100. The wiring is simple and can realize quick plugging and unplugging.

[0070] Correspondingly, the multiple stator modules 100 include a first arc-shaped stator module 100A and a second arc-shaped stator module 100A connected to each other. The connector 4 of the first arc-shaped stator module 100A is located inside the conveyor line 1000, and the connector 4 of the second arc-shaped stator module 100A is located inside the conveyor line 1000. The connector 4 of the first arc-shaped stator module 100A is electrically connected to the connector 4 of the second arc-shaped stator module 100A via a cable. In the above embodiment, the connectors 4 of the first arc-shaped stator module 100A and the second arc-shaped stator module 100A are both located inside the conveyor line 1000. Therefore, the cable can be directly plugged into the connectors 4 of the first arc-shaped stator module 100A and the second arc-shaped stator. With this configuration, the cable does not need to go around the top or bottom of the stator module 100 for connection, avoiding the cable from obstructing the movement of the mover module 200 or increasing the risk of collision. In addition, the cable length is designed to be shorter and the cost is lower.

[0071] In addition, each stator module 100 includes two connectors 4, and the two connectors 4 of each stator module 100 are electrically connected to the connectors 4 of the two adjacent stator modules 100 via cables. For example, in the closed conveyor line 1000 formed by multiple stator modules 100, each stator module 100 is connected to other stator modules 100 on both sides. Therefore, in order to ensure the electrical connection of the circuit boards 3 between stator modules 100, each stator module 100 needs to be provided with two connectors 4, which are electrically connected to the connectors 4 of the two adjacent stator modules 100 via cables, so as to realize the control of the entire line.

[0072] Referring to Figure 4, in some other embodiments, the conveyor line 1000 further includes a sensor array 300 and a sensing element 400. The sensor array 300 is connected to the base 1 of the stator module 100 and extends along a first direction A. The sensing element 400 is connected to the mover module 200 and is disposed opposite to the sensor array 300 in a third direction C, wherein the first direction A, the second direction B, and the third direction C are perpendicular to each other. Specifically, each base 1 has a top surface and a bottom surface 1a, and the sensor array 300 is disposed on the top surface of the base 1 along the extension direction of the stator module 100. The conveyor line 1000 includes multiple stator modules 100, and the sensor array 300 is disposed on each of the multiple bases 1. Specifically, the sensor array 300 is located at the first base 13; the sensing element 400 is disposed on the mover module 200, and the sensing element 400 is located on the side of the sensor array 300 facing away from the bottom surface 1a, and is relatively spaced from the sensor array 300 in the vertical direction of the stator; and each base 1 is provided with a circuit board 3, which is electrically connected to the corresponding sensor array 300.

[0073] Therefore, in the above structure, the first base 13 is used to support the sensor array 300, and the circuit board 3 is electrically connected to the corresponding sensor array 300. The circuit board 3 reads the position of the sensing element 400 sensed by the sensor array 300 to realize the positioning function of the moving module 200. The sensor array 300 and the sensing element 400 work together to control the position and movement of the moving module 200, realizing the precise conveying of workpieces or materials. The conveyor line 1000 uses a circular line driven by magnetic force to convey workpieces, which has a large carrying capacity and high energy efficiency, and is suitable for the transportation of workpieces or materials that move back and forth for a long time.

[0074] Furthermore, when multiple stator modules 100 are sequentially connected to form an annular conveyor line 1000, by placing the sensor array 300 on the top surface of the base 1, compared to surrounding the radial outer side of the annular conveyor line 1000, the sensor array 300 is easier to install and does not need to expand and occupy the radial space of the annular conveyor line 1000. The dimensions of the armature winding 2 and the mover module 200 in the radial direction can be designed to be smaller, thereby reducing the radial space occupied by the annular conveyor line 1000, improving space utilization, and reducing costs.

[0075] In some embodiments, the conveyor line 1000 includes multiple stator modules 100, which are sequentially connected to form a accommodating area 500 for placing an actuator. The multiple stator modules 100 are sequentially connected to enclose the accommodating area 500, which can be used to place the actuator. Placing the actuator within the accommodating area 500 does not occupy the radial space of the closed conveyor line 1000, thereby increasing space utilization and reducing the space occupied by the conveyor line 1000, facilitating miniaturization and weight reduction of the conveyor line 1000. Furthermore, the actuator includes robotic arms, gripping mechanisms, etc., which are not limited herein and can be used according to actual conditions.

[0076] The above description is merely a preferred embodiment of this application and is not intended to limit this application. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of this application should be included within the protection scope of this application.
