Description

TECHNICAL FIELD

[0001] The utility model relates to the technical field of magnetic drive, especially relates to a mover module and magnetic drive conveying line. BACKGROUND

[0002] The magnetic drive conveying line is a multi-mover intelligent conveying system based on the principle of linear motor, which is mainly composed of electromagnetic coupling movers and stators. Each mover does not need to drag a cable and can be independently controlled, which can adapt to the beat of different production stations and improve the flexibility of the production line.

[0003] In the related art, the mover of the magnetic drive line is in an I shape, and is guided by the side edges on both sides of the mover. Since the mover and the stator are guided by surface contact, if the distance between the side edge of the mover and the guiding surface of the stator is too small, the mover may be stuck when turning on the arc segment of the magnetic drive conveying line, and if the distance between the side edge of the mover and the guiding surface of the stator is too large, the mover may sway left and right when moving on the straight line segment of the magnetic drive conveying line. SUMMARY

[0004] The utility model aims at at least solving one of the technical problems existing in the prior art. To this end, the utility model provides a mover module, which can improve the stability of the mover module on the straight line segment and the smoothness of turning on the arc segment.

[0010] The mover module according to the utility model has at least the following beneficial effects:

[0011] In this embodiment, since the first guide wheel protrudes from the first sidewall, it can abut against the extension portion more effectively than the first sidewall. This reduces frictional resistance during the movement of the moving module. Furthermore, the first guide wheels on both sides of the moving module abut against the supporting members on both sides, preventing swaying and shaking during movement on straight sections and improving the stability of the moving module's transport. Additionally, because the contact area between the first guide wheel and the supporting member is small, the moving module can smoothly achieve turning in arc sections. Moreover, by using wear-resistant materials such as plastic or metal to make the first guide wheel, wear is significantly reduced, thereby improving the transport stability of the magnetic drive conveyor line.

[0012] According to some embodiments of the present invention, each of the first sidewalls is provided with at least one first mounting groove, and the first guide wheel is mounted in the first mounting groove.

[0046] The magnetic drive conveyor line is a multi-mover intelligent conveying system based on the principle of linear motors. The system mainly consists of electromagnetically coupled movers and stators. Each mover does not require a drag cable, can be independently controlled, and can adapt to the cycle time of different production stations, improving the flexibility of the production line.

[0047] In related technologies, the mover of the magnetic drive line is I-shaped and guided by the sides of the mover. Since the mover and stator are guided by surface contact, if the distance between the side of the mover and the guide surface of the stator is too small, it will easily cause jamming when turning in the arc section of the magnetic drive line. If the distance between the side of the mover and the guide surface of the stator is too large, it will easily cause the mover to sway left and right when moving on the straight section of the magnetic drive line.

[0048] To address the aforementioned problems, the first aspect of this application proposes a moving part module 10. This moving part module 10 also adopts an I-shaped structure and has good small-load conveying capacity. Specifically, the moving part module 10 includes a first main body 100 and a second main body 200. The first main body 100 has a first main body portion 110 for carrying the workpiece, such as... Figure 1 As shown, the first main body 110 is a flat plate structure. The top surface of the plate is used to abut against the workpiece. The top surface of the first main body 110 can be equipped with a magnetic attraction fixing mechanism, a negative pressure adsorption mechanism, a snap-fit ​​fixing mechanism, a bolt fixing mechanism, etc. After the workpiece is placed on the bottom surface of the first main body 110, it can be fixedly connected to prevent it from falling off during the conveying process. In some low-speed and gentle conveying conditions, the workpiece can also be placed directly on the first main body 110 without fixing, so as to improve the loading and unloading efficiency.

[0049] The second main body 200 includes a second main body portion 210, which is also a flat plate structure and is arranged parallel to the first main body portion 110. The first main body portion 110 and the second main body portion 210 are connected by a support structure, which is arranged vertically and has its two ends connected to the first main body portion 110 and the second main body portion 210, respectively.

[0050] It should be understood that the support structure can be an integrally formed structure, independently of the first main body 110 and the second main body 210. During the assembly of the mover module 10, the support structure is first connected to either the first main body 110 or the second main body 210, and then connected to the other to form an I-shaped mover module 10. Alternatively, the support structure can also be part of the first main body 100 or the second main body 200. For example, the first main body 100 may also include a first support portion 120, which protrudes from the bottom surface of the first main body 110. During the assembly of the mover module 10, the first support portion 120 is connected to the second main body 210 to form an I-shaped main structure of the mover module 10. It is understood that the support structure can also be part of the second main body 200.

[0051] In such Figure 1 and Figure 2 In the illustrated embodiment, the support structure is defined by a first main body 100 and a second main body 200. For example, the first main body 100 further includes a first support portion 120, which protrudes from the bottom surface of the first main body 110. The second main body 200 also includes a second support portion 220, which protrudes from the top surface of the second main body 210. When the first main body 100 and the second main body 200 are connected, the first support portion 120 and the second support portion 220 are mated together, thereby forming a complete support structure.

[0052] The second main body 210 is configured such that both side walls along the moving direction of the moving module 10 are first side walls 211, that is, the second main body 210 along the moving direction of the moving module 10 are first side walls 211. Figure 7 The two opposite sidewalls in the left-right direction shown are the first sidewalls 211. The moving part module 10 also includes at least one first guide wheel 300. The first guide wheel 300 is connected to the second main body 210, and the first guide wheel 300 is at least partially protruding from the first sidewall 211.

[0053] It should be noted that the first guide wheel 300 can be as follows: Figure 1 , Figure 2 and Figure 7 The first guide wheel 300 is installed in a slot on the first sidewall 211, as shown. Specifically, each first sidewall 211 has at least one first mounting slot 212, in which the first guide wheel 300 is installed. It is understood that one or more first guide wheels 300 can be installed in one first mounting slot 212. Each first sidewall 211 can have one or more first mounting slots 212.

[0054] In other embodiments (not shown in the figures), the first guide wheel 300 may also be directly connected to the second main body 210. For example, the first guide wheel 300 is disposed on the top surface of the second main body 210, and the first guide wheel 300 is partially protruding from the first sidewall 211.

[0055] To facilitate understanding of the moving principle and posture of the I-shaped moving module 10, the structure of the magnetic drive conveyor line of the second aspect embodiment of this application will be described in conjunction with the above description.

[0056] The magnetic drive conveyor line includes a conveyor module 20, such as Figure 3 As shown, the conveying module 20 can be linear, curved, wavy, etc., and can be arranged between the loading and unloading positions to complete the reciprocating conveying of the moving module 10 from a single loading position to a single unloading position. Alternatively, multiple loading or unloading positions can be arranged along the conveying line of the conveying module 20 to complete the material conveying along a linear path. In other embodiments, such as Figure 5 As shown, the magnetic drive conveyor line also includes a branch module 30, which can dock with at least three conveyor modules 20, thereby diverting the mover module 10 on one of the conveyor modules 20 to other conveyor modules 20, or merging the mover modules 10 on two of the conveyor modules 20 into the remaining conveyor modules 20.

[0057] The conveying module 20 includes a frame 21 and two parallel support members 22. Each support member 22 includes an extension 23 and an abutment 24.Figure 3 and Figure 4 As shown, the extension 23 is arranged vertically, with its lower end connected to the frame 21 and its upper end connected to the abutment 24. The abutment 24 is arranged horizontally, with two abutment 24 extending towards each other. A first guide groove is defined between the two abutment 24. The width of the first guide groove is smaller than the width of the first main body 110 of the moving module 10. Thus, when the moving module 10 is installed on the conveying module 20, the bottom surface of the first main body 110 abuts against the top surface of the abutment 24, and the second main body 210 is suspended between the extensions 23 on both sides. It can be understood that a magnetic plate 400 is connected to the bottom surface of the second main body 210, and a coil winding 25 is laid on the frame 21. There is a certain gap between the magnetic plate 400 and the frame 21, and they do not directly contact each other, so that when the magnetic plate 400 and the coil winding 25 are electromagnetically coupled, the moving module 10 is driven to move on the conveying module 20.

[0058] Understandably, in related technologies, the moving module moves and is guided by the first sidewall of the second main body abutting against the inner wall of the extension. This can easily lead to problems such as jamming or swaying. In this embodiment, since the first guide wheel 300 protrudes from the first sidewall 211, it is better than the first sidewall 211 abutting against the extension 23. On the one hand, this helps reduce the frictional resistance when the moving module 10 moves. On the other hand, the first guide wheels 300 on both sides of the moving module 10 abut against the support members 22 on both sides, which can prevent swaying when moving in a straight line and improve the stability of the moving module 10. In addition, since the contact area between the first guide wheel 300 and the support member 22 is small, the moving module 10 can smoothly achieve turning in an arc segment. Furthermore, by using wear-resistant materials such as plastic and metal to make the first guide wheel 300, the wear of the first guide wheel 300 can be greatly reduced, thereby improving the conveying stability of the magnetic drive conveyor line.

[0059] In related technologies, the structure of the mover module includes slider type and roller type. The slider type mover module can only pass through the straight section of the conveyor module, lacking flexibility. The roller type mover module relies on the roller for load bearing, resulting in greater wear on the roller. In the embodiment of this application, the mover module 10 uses a first main body 110 abutting with the abutting part 24 to bear the load, and a first guide wheel 300 abutting with the extension part 23 for movement guidance. This improves the flexibility of the mover module 10 while reducing the wear rate of the first guide wheel 300.

[0060] In some embodiments, the magnetic drive conveyor line further includes a branch module 30, which interfaces with at least three conveyor modules 20 to enable the mover module 10 to change direction, split flow, or merge flow on the magnetic drive conveyor line. Figure 5Taking the branch line module 30 as an example, the branch line module 30 is provided with a first branching channel 31, a second branching channel 32, and a merging channel 33. One end of the first branching channel 31 and the second branching channel 32 intersects with the merging channel 33, and the other end extends in different directions. The branch line module 30 also includes a guide member 34. The first end of the guide member 34 is disposed between the first branching channel 31 and the second branching channel 32, and the other end extends to the intersection of the channels. The guide member 34 can be driven to rotate with the first end as the rotation center so that one of the first branching channel 31 and the second branching channel 32 communicates with the merging channel 33.

[0061] In related technologies, when the moving module 10 moves onto the turnout module, the guide member directly abuts against the support structure of the moving module, thereby guiding the moving module to move. However, this guiding method causes significant wear on the support structure. Therefore, in some embodiments of this application, a second guide wheel 350 is designed on the support structure. When the moving module 10 moves onto the turnout module 30, the second guide wheel 350 abuts against the guide member 34 to achieve guiding and steering.

[0062] Specifically, such as Figure 2 and Figure 4 As shown, the first main body 110 and the second main body 210 are connected by a support structure. The support structure has a mounting cavity extending through its width. The moving part module 10 also includes a second guide wheel 350, which is disposed in the mounting cavity and at least partially protrudes from the side wall of the support structure. It should be noted that in this embodiment, both sides of the second guide wheel 350 protrude from the side walls of the support structure in the thickness direction.

[0063] Understandably, the second guide wheel 350 replaces the support structure and contacts the guide member 34. While reducing frictional resistance and facilitating the movement of the moving module 10, it also improves the durability of the support structure and avoids the reduction in the service life of the moving module 10 due to excessive wear of the support structure.

[0064] Furthermore, the support structure can be formed by connecting the first main body 100 and the second main body 200. Specifically, the first main body 100 includes a first main body portion 110 and a first support portion 120 protruding from the bottom surface of the first main body portion 110, and the second main body 200 includes a second main body portion 210 and a second support portion 220 protruding from the top surface of the second main body portion 210. The first support portion 120 and the second support portion 220 are joined to form the support structure. The first support portion 120 is provided with a second mounting groove 121, and the second support portion 220 is provided with a third mounting groove 221. The second mounting groove 121 and the third mounting groove 221 are correspondingly arranged and connected, thereby forming a mounting cavity for accommodating the second guide wheel 350.

[0065] likeFigure 6 As shown, a limiting groove 111 is provided on the bottom surface of the first main body 110, and the second mounting groove 121 communicates with the limiting groove 111. The bottom of the limiting groove 111 is provided with a first positioning protrusion 112, such as... Figure 2 and Figure 6 As shown, the first positioning protrusion 112 is an annular protrusion, and the second guide wheel 350 includes a through hole. The first positioning protrusion 112 is inserted into one end of the through hole, thereby playing a positioning role. The bottom of the third mounting groove 221 is provided with a second positioning protrusion 222, which is inserted into the other end of the through hole, playing a positioning role on the other side. Furthermore, the first positioning protrusion 112 and the second positioning protrusion 222 can also serve as the rotation shaft of the second guide wheel 350.

[0066] Based on the foregoing, the sidewalls of the second main body 210 on both sides along the moving direction of the moving sub-module 10 are designated as first sidewalls 211, and the sidewalls at both ends of the second main body 210 along the moving direction of the moving sub-module 10 are designated as second sidewalls 213, that is, as follows Figure 7 The sidewall shown in the front-rear direction is the second sidewall 213. It can be understood that the first sidewall 211 and the second sidewall 213 are alternately arranged along the circumference of the second main body 210. Each second sidewall 213 smoothly transitions to the adjacent first sidewall 211, thereby avoiding collision damage caused by stress concentration when the moving part module 10 moves forward or backward.

[0067] Furthermore, a guide surface 214 is also provided on the first side wall 211, which is used to reduce the intensity of collisions during the movement of the moving module 10. The moving module 10 can pass smoothly when it faces the arc segment of the conveying module 20 by using inclined or curved surfaces for abutment guidance.

[0068] Specifically, such as Figure 7 As shown, the moving module 10 is configured with a central axis, which is set along the moving direction of the moving module 10. The second sidewall 213 is provided with a guide surface 214, and the distance from the guide surface 214 to the central axis gradually decreases along the moving direction of the moving module 10. It should be noted that since the moving module 10 can move forward or backward, two guide surfaces 214 are provided on the second sidewall 213. It can be understood that the guide surface 214 can be an inclined surface or a curved surface.

[0069] The second aspect of this application also provides a magnetic drive conveyor line, which includes at least a conveyor module 20. In other embodiments, the magnetic drive conveyor line also includes a branch module 30.

[0070] The embodiments of the present invention have been described in detail above with reference to the accompanying drawings. However, the present invention is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of the present invention. Furthermore, the embodiments of the present invention and the features thereof can be combined with each other unless otherwise specified.
