Description

Technical Field

[0001] This utility model relates to the field of transmission equipment technology, and more specifically, to a conveying system. Background Technology

[0002] In the fields of modern transportation and industrial automation, moving-magnet permanent magnet linear motors are receiving increasing attention as a novel transportation technology. Transportation systems using moving-magnet permanent magnet linear motors consist of a fixed stator and a moving rotor. The interaction between the stator and rotor causes the rotor to move linearly. For example, the rotor includes a permanent magnet that generates a constant magnetic field. The stator includes coils; when current flows through the coils, according to Ampere's law, the coils generate a magnetic field. This magnetic field interacts with the magnetic field of the permanent magnet, causing the rotor of the motor to move linearly.

[0003] However, in practical applications, each coil module usually needs to be paired with a corresponding controller to control the current flowing through the coil module. When there are many coil modules, the cost and size of the transportation system will be relatively large. Utility Model Content

[0033] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments.

[0036] like Figures 1 to 3As shown, embodiments of this application provide a conveying system. Some embodiments of the conveying system of this application include: a first linear stator 10 and a second linear stator 20; the first linear stator 10 includes a first stator body 11, a first controller, and a plurality of first coil modules 12. The first stator body 11 extends along a preset line, and the plurality of first coil modules 12 are disposed on the first stator body 11 along the preset line. The first controller is disposed on the first stator body 11, and the plurality of first coil modules 12 are all electrically connected to the first controller; the second linear stator 20 includes a second stator body 21, a second controller, and a second coil module 22. The second controller and the second coil module 22 are both disposed on the second stator body 21, and the second controller is electrically connected to the second coil module 22; wherein, the first linear stator 10 and the second linear stator 20 are spliced ​​together.

[0037] Applying the technical solution of this embodiment, the conveying system includes a first linear stator 10 and a second linear stator 20 spliced ​​together, making the conveying system detachable for easy transportation and storage; the first linear stator 10 includes a first stator body 11, a first controller, and a plurality of first coil modules 12. The first stator body 11 extends along a preset line, and the plurality of first coil modules 12 are arranged on the first stator body 11 along the preset line. The preset line can be a curve, a straight line, or a combination of curves and straight lines, so that the mover 30 cooperating with the conveying system can move along a preset path, making the movement path more flexible; the second linear stator 20 includes a second stator body 21, a second controller, and a second coil module 22, the second controller and the first... Both coil modules 22 are mounted on the second stator body 21. The second controller is electrically connected to the second coil module 22 to control the energizing current of the second coil module 22. The first linear stator 10 and the second linear stator 20 are spliced ​​together to realize the installation of the conveying system. The first controller is mounted on the first stator body 11, and multiple first coil modules 12 are electrically connected to the first controller. Compared to a one-to-one correspondence between the controller and the coil module, using the first controller to electrically control the energizing current of multiple first coil modules 12 reduces the number of controllers, thereby reducing controller cascading and communication overhead. Simultaneously, it allows for miniaturization of the conveying system and controls its manufacturing cost. Therefore, the technical solution of this embodiment effectively solves the problems of high cost and large size in related technologies for transportation systems.

[0038] It is understood that, in this embodiment, multiple first coil modules 12 are electrically connected to a first controller, enabling a single first controller to control the power on / off of multiple first coil modules 12. Compared to related technologies, where each coil module is electrically connected to a controller, and the controllers are cascaded to control the power on / off of each coil, this embodiment avoids the cascading of multiple controllers. This reduces the number of connecting cables and communication optical fibers, resulting in lower costs and cleaner wiring. Furthermore, it reduces the communication load during signal transmission from multiple controllers, improving communication efficiency. In this embodiment, the first linear stator 10 includes multiple first coil modules 12, allowing the first linear stator 10 to have a longer conveying distance and increasing the versatility of the conveying system layout.

[0039] The conveying system of this application embodiment reduces the overall communication load of the conveying system by setting a first linear stator 10 and a second linear stator 20, enabling the conveying system to respond more quickly to relevant power on / off commands; when used in conjunction with an external PLC or other execution structure, it can reduce the command response time and thus improve processing efficiency.

[0040] It should be noted that the preset lines can be curves, straight lines, or a combination of curves and straight lines. In some embodiments, the preset lines can be composed entirely of curves, or entirely of straight lines, or a combination of curves and straight lines, thereby giving the preset curves a variety of shapes.

[0041] It should be noted that "multiple first coil modules 12 are all electrically connected to the first controller" means that multiple first coil modules 12 are all connected to the first controller for both signal and power supply; "the second controller is electrically connected to the second coil module 22" means that the second controller is connected to the second coil module 22 for both signal and power supply. As for the first controller and the second controller, they can be connected in series or connected to an external upper-level control device respectively.

[0042] like Figures 3 to 5As shown, the first stator body 11 includes a first housing 111. The first controller includes a control board 43 and a connector 44 disposed within the first housing 111. The control board 43 is the core control component of the conveying system. Its main function is to manage and control the current supply of the first coil module 12 to achieve precise motion control of the mover 30. The control board 43 can process signals from an external control system (such as a PLC) and convert them into control commands suitable for the coil module, thereby realizing automated and intelligent control of the system. The connector 44 provides a signal and power transmission path, enabling effective electrical connection between multiple control modules and between the control board 43 and the external control system. Multiple first coil modules 12 are mounted on the first housing 111 and extend outward from the first housing 111. The control board 43 includes multiple control modules, which are connected one-to-one with the multiple first coil modules 12. Two control modules are electrically connected through the connector 44. In related technologies, since the controller and coil module are set up accordingly and multiple controllers are connected in series, a large number of wires are needed to connect multiple controllers. In this embodiment, the number of controllers is reduced, which also reduces the amount of wires used. The two control modules can be connected by bonding wires or by copper foil on the PCB board.

[0043] It is understood that in this embodiment, multiple first coil modules 12 are fixedly installed to the first housing 111. Compared with the scheme of sequentially splicing multiple stators along the conveying direction in related technologies, this embodiment can reduce the splicing error generated during the splicing of multiple stators. By fixing multiple first coil modules 12 to the first housing 111, a longer conveying length can be achieved by setting only a single first linear stator 10. Furthermore, by reducing the number of stators, the splicing error of the stators is reduced, so that the conveying system has higher setting accuracy during setting, thereby improving the conveying accuracy of the mover 30.

[0044] like Figures 3 to 5As shown, the control board 43 has a first connection terminal 13 and a second connection terminal 14. Multiple control modules include a first control module 41 and at least one second control module 42. The first connection terminal 13 and the second connection terminal 14 are disposed on the first control module 41, and at least one second control module 42 is electrically connected to the first control module 41. Specifically, the first connection terminal 13 and the second connection terminal 14 serve as the main input or output ports of the control board 43. Their main function is to receive power and control signals from external structures, then distribute the power to each coil module, and simultaneously transmit the control signals to the first control module 41 for further processing and distribution; or, to transmit the power and control signals from the first control module 41 to other structures (e.g., the next-stage linear stator). Multiple second control modules 42 are used. By setting the first control module 41 as a relay station for control information, and then directly transmitting the control information to multiple second control modules 42 through the first control module 41, compared to a scheme where multiple control modules are cascaded and control information is transmitted sequentially, this embodiment reduces the number of cascades and avoids the accumulation of time delays.

[0045] like Figure 3 as well as Figure 4 As shown, the first connection terminal 13 includes an electrical input terminal 131 and a signal input terminal 132, the second connection terminal 14 includes an electrical output terminal 141 and a signal output terminal 142, and the first linear stator 10 also includes a second insertion interface 112 disposed on the first housing 111. The electrical input terminal 131, the signal input terminal 132, the electrical output terminal 141 and the signal output terminal 142 are all disposed at the second insertion interface 112. Electrical input terminal 131, signal input terminal 132, electrical output terminal 141, and signal output terminal 142 each have different functions. Electrical input terminal 131 is an interface for receiving power, typically connected to the main power line of the power supply box, or connected to the electrical output terminal 141 of the upstream control module. Signal input terminal 132 is mainly used to receive signals containing instructions for operating the coil module (e.g., the first coil module 12), such as the energizing sequence, current magnitude, and frequency. Electrical output terminal 141 is an interface for supplying power to downstream structures. Signal output terminal 142 is used to send control signals to downstream structures, containing instructions for operating the coil module (e.g., the first coil module 12). In this way, electrical input terminal 131, signal input terminal 132, electrical output terminal 141, and signal output terminal 142 are all integrated into a single connector, allowing operators to connect or disconnect multiple terminals with a single plug-in / plug-out operation.

[0046] In addition, such as Figure 5As shown, in other embodiments, the first linear stator 10 further includes a plurality of first connectors disposed on the first housing 111, with the electrical input terminal 131, signal input terminal 132, electrical output terminal 141, and signal output terminal 142 each corresponding to one of the first connectors. This arrangement facilitates maintenance by allowing personnel to perform separate testing and maintenance on the electrical input terminal 131, signal input terminal 132, electrical output terminal 141, and signal output terminal 142.

[0047] like Figure 1 As shown, the first coil module 12 is a first arc-shaped structure, and the arc of the first arc-shaped structure is greater than 0 and less than or equal to 90°. The arc of the first arc-shaped structure can be 15°, 30°, 45°, 60°, 75° or 90°. In this way, transmission paths with different degrees of curvature required by the user can be spliced ​​together by using first arc-shaped structures with different arcs, thereby improving the user experience.

[0048] like Figure 1 As shown, the first stator body 11 has a second arc-shaped structure, with an arc angle greater than 30° and less than or equal to 270°. Specifically, this allows the first stator body 11 to accommodate multiple first coil modules 12, while also adapting to different installation spaces in the conveying system. The arc angle of the first arc-shaped structure can be 30°, 60°, 90°, 120°, 150°, 180°, 210°, 240°, or 270°.

[0049] like Figure 1 As shown, the thickness of the first coil module 12 is greater than or equal to 7.2 mm and less than or equal to 9.4 mm. Specifically, the first coil module 12, meeting the above requirements, provides sufficient thickness to accommodate the coils stacked within the coil module, while also preventing the first coil module 12 from becoming excessively thick. Figures 1 to 4 As shown, the thickness of the first coil module 12 can be 7.2mm, 7.8mm, 8mm, 8.5mm or 9.4mm.

[0050] like Figure 1As shown, the first coil module 12 has an inner edge and an outer edge. The inner edge is a first arc structure, and the outer edge is a second arc structure. The first and second arc structures are concentrically arranged. The diameter a of the outer edge is greater than or equal to 508 mm and less than or equal to 622 mm, and the diameter b of the inner edge is greater than or equal to 414 mm and less than or equal to 506 mm. This arrangement ensures that the first coil module 12 has sufficient width to support the mover 30 and generate sufficient pushing force on the mover 30. The diameter a of the outer edge can be 508 mm, 525 mm, 550 mm, 565 mm, 600 mm, or 622 mm, and the diameter b of the inner edge can be 414 mm, 437 mm, 450 mm, 460 mm, 488 mm, or 506 mm.

[0051] like Figure 2 as well as Figure 3 As shown, the first stator body 11 also includes a second housing 113 spliced ​​with the first housing 111. The first linear stator 10 also includes a fan structure disposed within the second housing 113. The first housing 111 has an air inlet 114 and an air outlet 115. The fan structure is disposed corresponding to the air inlet 114 to dissipate heat from the control board 43. Specifically, in this embodiment, the fan structure can be an axial fan. The fan structure is disposed corresponding to the air inlet 114 to blow air into the cavity of the first housing 111 to dissipate heat from the control board 43, and can also dissipate heat from the first coil module 12 through the air outlet 115.

[0052] Furthermore, in this embodiment, the multiple first coil modules 12 have the same shape and are all arc-shaped structures. This configuration enables the mass production of the first linear stator 10, thereby reducing its production cost.

[0053] In addition, such as Figure 8As shown, the first coil module 12 includes a first coil layer 123 and a second coil layer 124 stacked together. The first coil layer 123 includes a plurality of first coils, which include a first U-phase coil 1231, a first V-phase coil 1232 and a first W-phase coil 1233 alternately arranged along a preset line extension direction. The second coil layer 124 includes a plurality of second coils, which include a second U-phase coil 1241, a second V-phase coil 1242 and a second W-phase coil 1243 alternately arranged along a preset line extension direction. The first coils and second coils are staggered in the direction from the first coil layer 123 to the second coil layer 124, and the phase of one first coil is different from the phase of the two adjacent second coils. The phrases "alternating arrangement of the first U-phase coil 1231, the first V-phase coil 1232, and the first W-phase coil 1233" and "alternating arrangement of the second U-phase coil 1241, the second V-phase coil 1242, and the second W-phase coil 1243" do not imply that the U-phase coils, V-phase coils, and W-phase coils are arranged in this order. Rather, the alternating order can be changed as needed. In short, the phases of a coil and its two adjacent coils on the same layer are not the same (the phases of these three coils are also different from each other). For example, in this embodiment, such as... Figure 4 As shown, the first coil layer 123 cycles in sequence with the V phase, U phase, and W phase, and the second coil layer 124 cycles in sequence with the U phase, W phase, and V phase. This forms a coil winding consisting of the second U phase coil 1241, the first V phase coil 1232, and the second W phase coil 1243, and a coil winding consisting of the first U phase coil 1231, the second V phase coil 1242, and the first W phase coil 1233. This reduces the cogging force of the mover 30.

[0054] like Figure 9 As shown, in some embodiments, the first coil module 12 includes a first body 121, at least one end of the first body 121 is provided with a first protrusion 122, and the second coil module 22 includes a second body 221, at least one end of the second body 221 is provided with a second protrusion 125, and the first protrusion 122 and the second protrusion 125 are stacked along the height direction. Specifically, the first coil module 12 is provided with a first coil, the second coil module 22 is provided with a second coil, the first protrusion 122 is also provided with a first coil, and the second protrusion 125 is also provided with a second coil. In this way, the first coil in the first protrusion 122 and the second coil in the second protrusion 125 are spliced ​​together, thereby making the mover 30 pass more smoothly between the first coil module 12 and the second coil module 22.

[0055] like Figure 6As shown, in some embodiments, the first coil module 12 includes a first body 121, at least one end of the first body 121 is provided with a first protrusion 122, wherein the end of the first body 121 opposite to the first protrusion 122 is also provided with a second protrusion 125, the second protrusion 125 and the first protrusion 122 are spaced apart along the height direction, for two adjacent first coil modules 12, the first protrusion 122 of one first coil module 12 and the second protrusion 125 of the other first coil module 12 are stacked along the height direction. Specifically, the first coil is provided in the first coil module 12, and the first coil is also provided in both the first protrusion 122 and the second protrusion 125, so that the first coil in the first protrusion 122 and the first coil in the second protrusion 125 are spliced ​​together, thereby making the mover 30 move more smoothly in the first linear stator 10.

[0056] More specifically, the surface of the first body 121 away from the second protrusion 125 and the surface of the first protrusion 122 away from the second protrusion 125 are flush, and the surface of the first body 121 away from the first protrusion 122 and the surface of the second protrusion 125 away from the first protrusion 122 are also flush. In this way, the first body 121, the first protrusion 122 and the other first body 121, or the first body 121, the second protrusion 125 and the other first body 121, all have flat surfaces, which facilitates the smooth movement of the mover 30.

[0057] like Figure 7 As shown, in some embodiments, the first coil module 12 includes a first body 121, at least one end of the first body 121 is provided with a first protrusion 122, and for two adjacent first coil modules 12, the two first protrusions 122 are stacked along the height direction. The first coil module 12 is provided with a first coil, and the first protrusion 122 is also provided with a first coil. In this way, the first coils of the stacked first protrusions 122 can be spliced ​​together, thereby making the mover 30 move more smoothly when passing through the two first coil modules 12.

[0058] like Figure 2 as well as Figure 3 As shown, in some embodiments, the conveying system further includes a mover 30, which includes a permanent magnet array 31 for coupling with a first coil module 12 or a second coil module 22 to move the mover 30 along the extension direction of the conveying system. The permanent magnet array 31 enables the mover 30 to be electromagnetically coupled to a linear stator, thereby generating a driving force between the mover 30 and the linear stator to move the mover 30.

[0059] Furthermore, the first coil module 12 of the conveying system is a first plate-shaped structure, and the permanent magnet array 31 has a first permanent magnet array. The surface of the first plate-shaped structure facing the first permanent magnet array forms a first coupling surface, which is located within a preset vertical plane, thus making the lateral dimension of the conveying system smaller. Alternatively, the first coil module 12 of the conveying system can be a second plate-shaped structure, and the permanent magnet array 31 has a second permanent magnet array. The surface of the second plate-shaped structure facing the second permanent magnet array forms a second coupling surface, which is located within a preset lateral plane, thus making the vertical dimension of the conveying system smaller. These different forms of conveying systems can adapt to different customer needs and accommodate different installation spaces.

[0060] In the description of this utility model, it should be understood that "multiple" means two or more. Directional terms such as "front, back, up, down, left, right," "horizontal, vertical, perpendicular, horizontal," and "top, bottom" indicate directions or positional relationships based on the directions or positional relationships shown in the accompanying drawings. These terms are used solely for the convenience of describing this utility model and simplifying the description. Unless otherwise stated, these directional terms do not indicate or imply that the device or element referred to must have a specific orientation or be constructed and operated in a specific orientation, and therefore should not be construed as limiting the scope of protection of this utility model. The directional terms "inner" and "outer" refer to the inner or outer contours relative to the outline of each component itself.

[0061] For ease of description, spatial relative terms such as "above," "on top of," "on the upper surface of," "above," etc., are used herein to describe the spatial positional relationship of a device or feature as shown in the figures to other devices or features. It should be understood that spatial relative terms are intended to encompass different orientations in use or operation beyond the orientation of the device as described in the figures. For example, if the device in the figures were inverted, a device described as "above" or "on top of" other devices or structures would subsequently be positioned as "below" or "under" other devices or structures. Thus, the exemplary term "above" can include both "above" and "below." The device may also be positioned in other different ways (rotated 90 degrees or in other orientations), and the spatial relative descriptions used herein will be interpreted accordingly.

[0062] Furthermore, it should be noted that the use of terms such as "first" and "second" to define components is merely for the purpose of distinguishing the corresponding components. Unless otherwise stated, the above terms have no special meaning and therefore cannot be construed as limiting the scope of protection of this utility model.

[0063] The above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Various modifications and variations can be made to this utility model by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
