DETAILED DESCRIPTION

[0047] In order to make the purpose, technical solution and advantages of the present application more clearly understood, the present application is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present application and are not used to limit the present application.

[0048] See also Figures 1 to 3 , a magnetic drive conveying system 100 provided in an embodiment of the present application, the magnetic drive conveying system 100 includes a stator module 10, a mover module 20, a first detection component 30 and a second detection component 40, a plurality of stator modules 10 can be sequentially spliced ​​to form a stator conveying line, the mover module 20 can be magnetically coupled with the stator module 10, so that the stator conveying line can drive the mover module 20 to move along the conveying direction of the magnetic drive conveying system 100, the first detection component 30 and the second detection component 40 can both detect the position of the mover module 20, when one of the first detection component 30 and the second detection component 40 cannot be used due to adverse factors such as installation error and damage, the position of the mover module 20 can also be detected by the other of the first detection component 30 and the second detection component 40, which can improve the movement accuracy of the mover module 20.

[0049] Specifically, the stator module 10 can include a stator base 1, a stator body 2 and an armature winding 3. The stator base 1 serves as a supporting component for supporting the magnetic drive conveying system 100. The material of the stator base 1 can be a metal material, including but not limited to stainless steel and aluminum, etc. Of course, the stator base 1 can also have some parts made of metal and some parts made of plastic, rubber and other materials. The embodiment of the present application does not limit this. For example, the parts of the stator base 1 that play a supporting role are made of metal.

[0050] The stator body 2 can be arranged on the top of the stator base 1, and the stator body 2 can be extended along the conveying direction, the armature winding 3 can be arranged on the stator body 2, and the armature winding 3 can also be extended along the conveying direction, and the armature winding 3 and the stator base 1 are spaced apart, so that there can be an installation space between the armature winding 3 and the stator base 1 to reasonably place the mover module 20.

[0051] By magnetically coupling the mover module 20 with the armature winding 3 , when the armature winding 3 is energized, the armature winding 3 can drive the mover module 20 to move in the conveying direction, so that the mover module 20 can be controlled to stop or move by controlling the on and off of the armature winding 3 .

[0052] The first detection assembly 30 can be arranged between the armature winding 3 and the stator base 1, or it can be said that the first detection assembly 30 is arranged in the installation space, and the space can be reasonably used to install the first detection assembly 30, so that the structure of the magnetic drive conveying system 100 is more compact. The first detection assembly 30 can include a first sensing structure 301 and a first reading member 302, one of which can be arranged on the stator base 1, and the other of which can be arranged on the mover module 20. When the armature winding 3 drives the mover module 20 to move along the conveying direction, the first reading member 302 can be used in conjunction with the first sensing structure 301 to detect the position of the mover module 20, which can improve the movement accuracy of the mover module 20.

[0053] Optionally, the first sensing structure 301 can be a magnetic sensor, and the first reading member 302 can be a magnetic scale. The first sensing structure 301 is set on the moving module 20, and the first reading member 302 is set on the stator base 1. When the moving module 20 moves along the conveying direction, the first sensing structure 301 moves with the moving module 20, and when the first sensing structure 301 passes through the corresponding reading point on the first reading member 302, a corresponding electrical signal can be generated. After the electrical signal is processed, the position of the moving module 20 can be detected. It should be noted that the first sensing structure 301 can also be set on the stator base 1, and the first reading member 302 can be set on the moving module 20. When the moving module 20 moves along the conveying direction, the first reading member 302 moves with the moving module 20, and when the first reading member 302 passes through the first sensing structure 301, a corresponding electrical signal can also be generated, thereby detecting the position of the moving module 20.

[0054] The second detection assembly 40 can also be arranged between the armature winding 3 and the stator base 1, that is, the second detection assembly 40 is arranged in the installation space, and the second detection assembly 40 is arranged at a distance from the first detection assembly 30. By arranging the first detection assembly 30 and the second detection assembly 40 at different positions, it is possible to prevent the installation error at the same place from affecting the detection accuracy of the first detection assembly 30 and the second detection assembly 40. The second detection assembly 40 can include a second sensing structure 401 and a second reader 402, one of which can be arranged on the stator body 2, and the other of which can be arranged on the mover module 20. When the armature winding 3 drives the mover module 20 to move along the conveying direction, the second reader 402 can be used in conjunction with the second sensing structure 401 to detect the position of the mover module 20, which can improve the movement accuracy of the mover module 20.

[0055] Optionally, the second sensing structure 401 can also be a magnetic sensor, and the second reading element 402 can also be a magnetic scale. The second sensing structure 401 is set on the mover module 20, and the second reading element 402 is set on the stator body 2. The principle of the second sensing structure 401 and the second reading element 402 are used in conjunction with each other, which is the same as the principle of the first sensing structure 301 and the first reading element 302, and will not be repeated here. It should be noted that the setting positions of the second sensing structure 401 and the second reading element 402 can also be interchanged.

[0056] When the first sensing structure 301 and the first reading element 302 cannot be used due to installation errors, damages and other adverse factors, the position of the moving sub-module 20 can be detected by using the second sensing structure 401 and the second reading element 402 in combination. Similarly, when the second sensing structure 401 and the second reading element 402 cannot be used, the position of the moving sub-module 20 can be detected by using the first sensing structure 301 and the first reading element 302. Therefore, the position of the moving sub-module 20 can be detected by setting the first detection component 30 and the second detection component 40. When one of the first detection component 30 and the second detection component 40 cannot be used due to installation errors, damages and other adverse factors, the position of the moving sub-module 20 can also be detected by using the other of the first detection component 30 and the second detection component 40, thereby improving the movement accuracy of the moving sub-module 20.

[0057] See also Figure 1 and Figure 4 In some embodiments, the stator base 1 can include a first base 11 and a second base 12, and the first base 11 can be provided with one of a first sensing structure 301 and a first reading member 302, and the other of the first sensing structure 301 and the first reading member 302 can be arranged on the movable module 20, and the second base 12 can be arranged on the side of the first base 11, and the top of the second base 12 is higher than the top of the first base 11, and the stator body 2 can be provided on the second base 12, and a gap cavity can be provided between the stator body 2 and the first base 11 along a direction perpendicular to the coupling surface of the armature winding 3, and a second sensing structure 401 and a second reading member 402 can be embedded in the interior of the stator body 2, and the other of the second sensing structure 401 and the second reading member 402 can be arranged on the movable module 20 and located at the gap cavity.

[0058] Optionally, the stator base 1 can include a bottom plate, and the shape of the bottom plate can be circular, rectangular, square, polygonal, etc. The specific shape of the bottom plate is not limited. The following takes the bottom plate as a rectangle as an example for explanation. The first base 11 can be arranged on the bottom plate, and the first base 11 is extended along the conveying direction. The first base 11 encloses a frame structure on the bottom plate. The second base 12 can also be arranged on the bottom plate, and the second base 12 is located in the frame structure enclosed by the first base 11. The top of the second base 12 can extend out of the frame structure, so that the top of the second base 12 is higher than the top of the first base 11.

[0059] The stator body 2 can be fixed to the top end of the second base 12, and the stator body 2 can also be extended along the conveying direction, and the stator body 2 can be located above the first base 11, so that a gap cavity can be formed between the stator body 2 and the first base 11, and an armature winding 3 can be provided on the stator body 2, and the armature winding 3 is extended along the extension direction of the stator body 2, and the coupling surface of the armature winding 3 can be arranged parallel to the top surface of the first base 11, so that there can be a gap between the armature winding 3 and the first base 11.

[0060] When the armature winding 3 drives the mover module 20 to move along the conveying direction, the first base 11 will not interfere with the movement of the mover module 20, and during the movement of the mover module 20, the mover module 20 can always be arranged relative to a part of the first base 11. By arranging one of the first sensing structure 301 and the first reading member 302 on the first base 11, and arranging the other of the first sensing structure 301 and the first reading member 302 on the mover module 20, during the movement of the mover module 20, the first sensing structure 301 and the first reading member 302 can always cooperate with each other to detect the position of the mover module 20, thereby improving the accuracy of position detection.

[0061] Similarly, by embedding one of the second sensing structure 401 and the second reading element 402 inside the stator body 2, and setting the other of the second sensing structure 401 and the second reading element 402 on the movable module 20 and located in the gap cavity, the second sensing structure 401 and the second reading element 402 can always cooperate with each other during the movement of the movable module 20 to detect the position of the movable module 20, thereby improving the accuracy of position detection, and making full use of the space between the stator body 2 and the first base 11 to set the second detection component 40, thereby improving space utilization.

[0062] See also Figures 1 to 5 In some embodiments, the stator module can further include a guide rail member 4, which can be arranged on the first base 11, and the guide rail member 4 can be extended along the conveying direction. The movable module 20 can include a sliding member 201, and the sliding member 201 slides with the guide rail member 4, and the first reading member 302 is arranged on the first base 11, and the second reading member 402 is arranged on the stator body 2, and the first reading member 302 and the second reading member 402 are respectively located on opposite sides of the guide rail member 4.

[0063] Optionally, the top surface of the first base 11 can form a flat supporting surface, the guide rail member 4 can be fixed to the supporting surface, and the guide rail member 4 is located between the first base 11 and the armature winding 3, the sliding member 201 can be set at the bottom of the movable module 20, and the sliding member 201 and the guide rail member 4 slide together to guide the movable module 20 to move along the conveying direction, so that the movable module 20 moves more smoothly and can prevent the movable module 20 from shaking.

[0064] By setting the first reading member 302 on the first base 11, further, the circumferential side of the first base 11 is provided with a positioning groove, and the first reading member 302 is fixedly set in the positioning groove, thereby avoiding the occupation of additional space and improving the installation accuracy of the first reading member 302, and improving the space utilization rate, the second reading member 402 is set on the stator body 2, and the first reading member 302 and the second reading member 402 are respectively located on the opposite sides of the guide member 4, so that the first reading member 302 and the second reading member 402 can detect the position of the moving submodule 20 from two different angles. This double detection method can verify each other, reduce errors, improve the overall position detection accuracy, and prevent the installation error at the same place from causing adverse effects on the first reading member 302 and the second reading member 402 at the same time. And the first reading member 302 and the second reading member 402 are distributed on both sides of the guide member 4, which can more effectively utilize the space, prevent excessive concentration of components on one side of the guide member 4, and make the magnetic drive conveying system 100 more compact.

[0065] See also Figures 3 to 5 In some embodiments, the first sensing structure 301 and the second sensing structure 401 are both arranged on the movable module 20, and the first sensing structure 301 and the second sensing structure 401 can be respectively arranged on opposite sides of the guide rail member 4, or the first sensing structure 301 and the second sensing structure 401 are arranged on the same side of the guide rail member 4.

[0066] Optionally, when the first sensing structure 301 and the second sensing structure 401 are respectively arranged on opposite sides of the guide rail member 4, the first sensing structure 301 and the second sensing structure 401 can respectively obtain position information from different sides of the guide rail member 4, which can improve the accuracy of position detection, and in a space with a complex structure or limited space, the first sensing structure 301 and the second sensing structure 401 are distributed on both sides of the guide rail member 4, which can adaptively improve space utilization. When the first sensing structure 301 and the second sensing structure 401 are arranged on the same side of the guide rail member 4, the installation process of the first sensing structure 301 and the second sensing structure 401 can be simplified, and the installation difficulty can be reduced.

[0069] To be more clear, one end of the connecting wire is inserted into the wiring port of the driver 5, and the connecting wire extends along the outer side surface of the first base 11 to the socket 112. The connecting wire passes through the socket 112 and then extends into the connecting cavity 121. The other end of the connecting wire is inserted into the wiring terminal 31 of the armature winding 3, so that the driver 5 on the first base 11 can be electrically connected to the armature winding 3 on the stator body 2. Setting the driver 5 on the first base 11 can reasonably utilize the space and prevent the driver 5 and the armature winding 3 from being concentrated on the second base 12.

[0073] In some embodiments, the detection accuracy of the first sub-reading point is the same as the detection accuracy of the second sub-reading point, so that when one of the first reading member 302 and the second reading member 402 is damaged, using the other of the first reading member 302 and the second reading member 402 to continue to detect the position of the movable module 20 will not affect the detection accuracy, and because the detection accuracy of the first reading point and the second reading point is the same, when the first reading member 302 and the second reading member 402 need to be replaced, replacement parts with the same accuracy can be selected without worrying about accuracy mismatch issues.

[0074] In some other embodiments, the detection accuracy of the second sub-reading point is greater than that of the first sub-reading point. Since the armature winding 3 and the second reading member 402 are both arranged on the stator body 2, the installation of the stator body 2 is difficult and installation errors are prone to occur. By setting a second sub-reading point with higher detection accuracy, the influence of installation errors on position detection can be reduced, thereby improving the detection accuracy.

[0075] See also Figures 3 to 5In some embodiments, the mover module 20 can include a mover body 202 and a permanent magnet array 203. The mover body 202 can be provided with a receiving groove 2021. The receiving groove 2021 passes through both ends of the mover body 202 along the conveying direction. The armature winding 3 is passed through the receiving groove 2021, and the permanent magnet array 203 can be arranged on the inner wall of the receiving groove 2021, and the permanent magnet array 203 can be magnetically coupled with the armature winding 3, so that the armature winding 3 can drive the mover body 202 to move along the conveying direction.

[0076] Specifically, when the mover body 202 is arranged on the armature winding 3, a first accommodating space 101 can be provided between the mover body 202 and the first base 11, and a second accommodating space 102 can be provided between the mover body 202 and the stator body 2. One of the first sensing structure 301 and the first reading member 302 can be provided on the mover body 202 and located in the first accommodating space 101. One of the second sensing structure 401 and the second reading member 402 can also be provided on the mover body 202 and located in the second accommodating space 102, so that the gap space can be fully utilized to set the first detection component 30 and the second detection component 40, so that the magnetic drive conveying system 100 is more compact as a whole and can save space.

[0077] Optionally, the first sensing structure 301 can be arranged on the bottom surface of the movable body 202 and located in the first accommodating space 101 , and the second sensing structure 401 can be arranged on the side of the movable body 202 and located in the second accommodating space 102 .

[0078] See also Figure 5 In some embodiments, a mounting portion 2022 can be provided on the mover body 202 , the mounting portion 2022 is extended toward the stator base 1 , and one of the first sensing structure 301 and the first reading member 302 is disposed on the mounting portion 2022 .

[0079] Optionally, a mounting portion 2022 can be provided on the bottom surface of the mover body 202, and the mounting portion 2022 protrudes toward the first base 11 relative to the bottom surface of the mover body 202, and the mounting portion 2022 has a mounting surface arranged toward the first base 11, and one of the first sensing structure 301 and the first reading element 302 can be arranged on the mounting surface, which can facilitate the installation of the first detection component 30.

[0080] See also Figure 2 and Figure 6 In some embodiments, the armature winding 3 can include a first winding 32, and the first winding 32 can include a linear winding 321 and an arc winding 322 arranged along the conveying direction, and the linear winding 321 and the arc winding 322 are integrally formed.

[0081] Optionally, the linear winding 321 and the arc winding 322 are integrally formed, which can prevent errors from occurring when the linear winding 321 and the arc winding 322 are spliced, so that the mover module 20 can move from the linear winding 321 to the arc winding 322 more smoothly, preventing the mover module 20 from shaking, and can also increase the detection accuracy of the first detection component 30 and the second detection component 40. After the linear winding 321 and the arc winding 322 are integrally formed, the steps of splicing the linear winding 321 and the arc winding 322 are reduced, and the magnetic drive conveying system 100 is also more convenient to install. The integral forming referred to in this embodiment can refer to the linear winding 321 and the arc winding 322 being printed together on the same circuit board, or the linear winding 321 and the arc winding 322 being wound together on the same stator tooth.

[0082] See also Figure 2 and Figure 7 In some embodiments, the armature winding 3 can include a second winding 33, a first protrusion 3221 is provided at one end of the arc winding 322 away from the linear winding 321, a second protrusion 331 is provided at one end of the second winding 33, and the first protrusion 3221 can be overlapped with the second protrusion 331.

[0083] Optionally, the end face of the arc winding 322 away from the linear winding 321 can protrude out of the first protrusion 3221 along the conveying direction, and one end face of the second winding 33 can also protrude out of the second protrusion 331 along the conveying direction. By overlapping the first protrusion 3221 and the second protrusion 331, the arc winding 322 can be connected to the second winding 33, which can reduce the difficulty of connecting the arc winding 322 and the second winding 33.

[0084] Optionally, the first protrusion 3221 is a square structure, the shape of the second protrusion 331 is the same as that of the first protrusion 3221, and the first protrusion 3221 and the second protrusion 331 are staggered in a direction perpendicular to the magnetic coupling surface of the armature winding 3, which can facilitate the overlap of the first protrusion 3221 and the second protrusion 331.

[0085] In some embodiments, a first coil can be provided inside the first protrusion 3221, and a second coil can be provided inside the second protrusion 331. When the first protrusion 3221 and the second protrusion 331 are overlapped, the first coil can be stacked with the second coil, so that there is still a magnetic field at the joint between the arc winding 322 and the second winding 33. When the movable module 20 moves to the joint between the arc winding 322 and the second winding 33, there is still a magnetic driving force to drive the movable module 20 to move along the conveying direction, thereby stably driving the movable module 20 to move and also improving the accuracy of position detection.

[0086] See also Figure 2In some embodiments, the second winding 33 can be in a straight line shape, and the length of the second winding 33 is greater than the length of the straight winding 321 .

[0087] Optionally, the armature winding 3 can include two first windings 32 and two second windings 33, the two ends of a first winding 32 are respectively connected to a second winding 33, and the two ends of a second winding 33 are also respectively connected to a first winding 32, so that the two first windings 32 and the two second windings 33 can form a circular conveying line, which can facilitate the circular conveying of the mover module 20, and the length of the second winding 33 is greater than the length of the linear winding 321, which can increase the conveying distance of the armature winding 3 and can convey more components.

[0088] See also Figure 6 In some embodiments, an arc winding 322 can be respectively provided at two opposite ends of the linear winding 321, and the two arc windings 322 can be bent and extended in the same direction.

[0089] Optionally, the first winding 32 can include a linear winding 321 and two arc-shaped windings 322, and the two arc-shaped windings 322 are located at opposite ends of the linear winding 321, and the two arc-shaped windings 322 are bent and extended in the same direction. When the linear winding 321 and the two arc-shaped windings 322 are integrally formed, a C-shaped first winding 32 can be formed. After the movable module 20 passes through the first winding 32, the movement direction of the movable module 20 can be changed, so that the movable module 20 moves in the opposite direction. This structural form of the first winding 32 can be used to assemble a circulating conveyor line.

[0090] In some other embodiments, the two arc windings 322 can be bent and extended in opposite directions. When the straight winding 321 and the two arc windings 322 are integrally formed, a first S-shaped winding 32 can be formed. After the movable module 20 passes through the first winding 32, the movement direction of the movable module 20 remains unchanged. To be more clear, the movement direction of the movable module 20 entering the first winding 32 is the same as the movement direction of the movable module 20 leaving the first winding 32. However, the conveying line body formed by the first winding 32 can form a corner structure, and the processing equipment can be installed at the corner to facilitate the processing of the workpiece conveyed to the first winding 32.

[0091] In some embodiments, the second reading member 402 is disposed on the stator body 2 , and the second reading member 402 includes a straight reading segment and an arc-shaped reading segment, and the straight reading segment and the arc-shaped reading segment are integrally formed and connected.

[0092] Optionally, the straight reading segment can be arranged relative to the straight line winding 321, and the arc-shaped reading segment can be arranged relative to the arc-shaped winding 322, and the extension direction of the second reading member 402 is the same as the extension direction of the first winding 32. The straight line reading segment and the arc-shaped reading segment are arranged as one piece, which can reduce the splicing steps of the straight line reading segment and the arc-shaped reading segment, and can increase the installation accuracy of the straight line reading segment and the arc-shaped reading, thereby increasing the accuracy of the second reading member 402 in detecting the position of the actuator module 20.
