Abstract
Description
Technical Field
[0001] This utility model belongs to the field of magnetic drive conveying technology, specifically relating to a moving module and a magnetic drive conveying device. Background Technology
[0002] Magnetic drive conveyors utilize the driving force of a magnetic field on a magnetic object. By controlling the distribution and intensity of the magnetic field, precise positioning and transport of the object are achieved. They mainly include a stator module, a mover module, a guide rail system, a control system, and a power supply system.
[0003] In related technologies, the moving module and the guide rail system work together, and with the cooperation of the stator module, the moving module can slide along the guide rail system. However, during the sliding process of the moving module along the guide rail system, there is a risk of derailment. Utility Model Content
[0004] The purpose of this application is to provide a moving module and a magnetic drive conveying device to solve the above-mentioned technical problems existing in the prior art.
[0005] This application is implemented as follows:
[0006] In a first aspect, embodiments of this application provide a moving submodule, including a frame and a first roller and a limiting structure mounted on the frame; the first roller is used to roll with a guide rail, the limiting structure is spaced apart from the first roller, and an installation gap adapted to the guide rail is formed between the first roller and the limiting structure; when the guide rail is installed in the installation gap, the limiting structure can limit the movement of the moving submodule to prevent it from disengaging from the guide rail along the width direction, and when the first roller rolls with the guide rail, there is an active gap between the limiting structure and the guide rail.
[0007] Secondly, embodiments of this application provide a magnetic drive conveying device, including the moving module provided in the first aspect embodiment.
[0008] The technical solution provided in this application can achieve the following beneficial effects:
[0009] In this application, by setting a first roller and a limiting structure, an installation gap adapted to the guide rail is limited between the two. The first roller rolls in cooperation with the guide rail, reducing the friction between the moving sub-module and the guide rail, thus ensuring that the moving sub-module can slide smoothly along the guide rail's direction. Furthermore, with the first roller rolling in cooperation with the guide rail, there is a play between the limiting structure and the guide rail. During normal movement of the moving sub-module, the limiting structure will not contact the guide rail, and will not affect the movement of the moving sub-module. When the first roller separates from the guide rail and the moving sub-module tends to detach from the guide rail, as the gap between the first roller and the guide rail increases, the limiting structure on the other side of the guide rail comes into contact with the guide rail. The limiting structure engages with the guide rail, preventing the gap between the first roller and the guide rail from increasing further, thereby preventing the moving sub-module from detaching from the guide rail.

The elements and arrangements described in the specific examples below are only for concise expression of the present invention and are merely examples, not intended to limit the present invention.
[0021] To make the objectives, technical solutions, and advantages of this utility model clearer, the technical solutions of this utility model will be described in detail below. Obviously, the described embodiments are only a part of the embodiments of this utility model, and not all of them. Based on the embodiments of this utility model, all other implementation methods obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.
[0022] The terms "first," "second," etc., used in the specification and claims of this application are used to distinguish similar objects and are not used to describe a specific order or sequence. It should be understood that such data can be interchanged where appropriate so that embodiments of this application can be implemented in orders other than those illustrated or described herein, and the objects distinguished by "first," "second," etc., are generally of the same class and are not limited in number; for example, a first object can be one or more.
[0023] This application provides a moving sub-module for use in a magnetic drive conveying device. In actual use, multiple stator modules 30 are spliced together along a preset path of the moving sub-module 10, and a guide rail 20 is installed on the spliced stator modules 30. The moving sub-module 10 moves and cooperates with the guide rail 20 to move and convey materials on the guide rail 20.
[0024] refer to Figures 1 to 4 as well as Figure 6As shown, the moving submodule 10 provided in this embodiment includes a frame 100, a first roller 200 mounted on the frame 100, and a limiting structure 300. The frame 100 is the basic structure of the moving submodule 10, serving as the mounting base for the first roller 200 and the limiting structure 300. The first roller 200 is used for rolling engagement with the guide rail 20. The limiting structure 300 is spaced apart from the first roller 200, and an installation gap 400 adapted to the guide rail 20 is formed between the first roller 200 and the limiting structure 300.
[0025] With the guide rail 20 installed at the installation gap 400, the guide rail 20 has a first roller 200 and a limiting structure 300 on each side. The first roller 200 is used for rolling engagement with the guide rail 20, and the first roller 200 can roll on the guide rail 20 along the guiding direction of the guide rail 20 to change the position of the moving sub-module 10 on the guide rail 20. The limiting structure 300 can limit engagement with the guide rail 20 to prevent the moving sub-module 10 from disengaging from the guide rail 20 along the width direction of the guide rail 20. The first roller 200 and the limiting structure 300 cannot contact the guide rail 20 simultaneously. When the first roller 200 is in rolling engagement with the guide rail 20, there is an active gap 500 between the limiting structure 300 and the guide rail 20. Figure 5 and Figure 7 As shown, the limiting structure 300 will not contact the guide rail 20 and will not affect the normal movement of the moving sub-module 10.
[0026] During the movement of the moving sub-module 10 along the guide rail 20, if the first roller 200 separates from the guide rail 20 and the moving sub-module 10 tends to detach from the guide rail 20, the distance between the first roller 200 and the guide rail 20 will gradually increase. At the same time, the distance between the limiting structure 300 on the other side of the guide rail 20 and the guide rail 20 will gradually decrease until the limiting structure 300 contacts the guide rail 20. The two limit each other and prevent the distance between the first roller 200 and the guide rail 20 from continuing to increase, thereby preventing the moving sub-module 10 from detaching from the guide rail 20.
[0027] The first roller 200 and the limiting structure 300 are located on both sides of the guide rail 20. When the moving submodule 10 wants to shift to one side of the guide rail 20, the structure on the other side of the guide rail 20 will engage with the guide rail 20 to limit its movement, thereby preventing the moving submodule 10 from detaching from the guide rail 20. In actual use, when the moving submodule 10 is overspeeding, overloaded, or subjected to excessive centrifugal force, the moving submodule 10 is at risk of derailment.
[0028] In the magnetic drive conveyor, there is an attractive force between the moving module 10 and the stator module 30 below the guide rail 20. Under the attraction of this force, the first roller 200 of the moving module 10 is stably attached to the guide rail 20. During subsequent use of the moving module 10, even if the moving module 10 tends to derail and the first roller 200 separates from the guide rail 20, the limiting structure 300, in cooperation with the guide rail 20, prevents the first roller 200 from further separating from the guide rail 20. The attractive force between the moving module 10 and the stator module 30 can then drive the first roller 200 to approach the guide rail 20 again and attach to it.
[0029] The part of the moving module 10 that is in contact with the stator module 30 is located on the same side of the guide rail 20 as the first roller 200. With this arrangement, the first roller 200 can be attached to the guide rail 20 under the adsorption of the stator module 30.
[0030] In the embodiments provided in this application, by improving the structure of the moving sub-module 10 and setting a limiting structure 300 on the frame 100, the moving sub-module 10 and the guide rail 20 are limited and matched, preventing the moving sub-module 10 from derailing, without the need to improve the existing guide rail 20 structure.
[0031] In some embodiments, if the width of the mounting gap 400 differs significantly from the width of the guide rail 20, the guide rail 20 can be directly installed into the mounting gap 400 during the assembly of the moving sub-module 10 and the guide rail 20. During the installation of the guide rail 20, it does not need to contact the first roller 200 or the limiting structure 300, making assembly more convenient. The position of the first roller 200 is adjusted by the adsorption force between the moving sub-module 10 and the stator module 30.
[0032] In other embodiments, the width of the mounting gap 400 is not significantly different from the width of the guide rail 20. During the installation of the guide rail 20, it is easy for the guide rail 20 to come into contact with the first roller 200 and the limiting structure 300. During assembly, attention must be paid to the position of the guide rail 20 to avoid excessive force applied after it has contacted the first roller 200 or the limiting structure 300, which could lead to excessive interaction forces between the guide rail 20 and the first roller 200 or the limiting structure 300. Simultaneously, because the width of the mounting gap 400 is small, the movement gap 500 between the limiting structure 300 and the guide rail 20 will not be too large, resulting in a better limiting effect of the limiting structure 300.
[0033] After the limiting structure 300 contacts the guide rail 20, the moving submodule 10 continues to move on the guide rail 20. In some embodiments, the friction between the limiting structure 300 and the guide rail 20 can be reduced by decreasing the contact area between them, thereby mitigating the impact of friction on the movement of the moving submodule 10.
[0034] In some embodiments of this application, the moving module 10 further includes a rotating shaft, and a limiting structure 300 is coaxially sleeved on the rotating shaft. The limiting structure 300 is connected to the frame 100 through the rotating shaft. The limiting structure 300 can rotate around the axis of the rotating shaft, and the axis of the rotating shaft is parallel to the rotation axis of the first roller 200. After the limiting structure 300 contacts the guide rail 20, the limiting structure 300 rotates while moving along the guide rail 20, thereby converting the sliding friction between it and the guide rail 20 into rolling friction, greatly reducing the friction between the limiting structure 300 and the guide rail 20.
[0035] The limiting structure 300 can be rotatably connected to the rotating shaft, and the rotating shaft can be fixedly connected to the frame 100; alternatively, the limiting structure 300 can be fixedly connected to the rotating shaft, and the rotating shaft can be rotatably connected to the frame 100. This application does not limit the distance connection relationship between the limiting structure 300 and the rotating shaft.
[0036] In some preferred embodiments of this application, the limiting structure 300 is detachably connected to the frame 100. The detachable limiting structure 300 allows for more flexible installation and use. The limiting structure 300 can be installed in advance, or it can be installed after the first roller 200 has engaged with the guide rail 20.
[0037] In some specific embodiments, the first roller 200 is pre-installed on the frame 100, and then the frame 100 is installed onto the guide rail 20. Since only the frame 100 is provided, when adjusting the relative position of the first roller 200 and the guide rail 20, there is no need to pay extra attention to the position of the limiting structure 300, which can improve the ease of installation of the frame 100. After the first roller 200 is attached to the guide rail 20, the limiting structure 300 is then installed onto the frame 100, completing the assembly of the moving submodule 10 and the guide rail 20.
[0038] Because there is a play 500 between the limiting structure 300 and the guide rail 20 when the first roller 200 is in rolling contact with the guide rail 20, it is unlikely that the limiting structure 300 and the guide rail 20 will touch during the subsequent assembly of the limiting structure 300. Assemblers can confirm by feel whether the limiting structure 300 and the guide rail 20 are touching, thus determining whether the dimensions of the limiting structure 300 are appropriate. If no contact occurs, it means that the limiting structure 300 and the guide rail 20 are not in contact, and there is the expected play 500 between them. If contact occurs, it means that the limiting structure 300 and the guide rail 20 are in contact. Assemblers can further observe whether there is a play 500 between the limiting structure 300 and the guide rail 20 to avoid the disappearance of the expected play 500 due to dimensional errors in the limiting structure 300.
[0039] Preferably, when the guide rail 20 is installed in the installation gap 400 and the first roller 200 is in rolling engagement with the guide rail 20, the width of the movable gap 500 between the limiting structure 300 and the guide rail 20 is between 0.5mm and 1mm. The width of the movable gap 500 should not be too wide. A wider gap results in a greater separation distance between the first roller 200 and the guide rail 20, making it difficult for the first roller 200 to reset subsequently, or increasing the difficulty of resetting the first roller 200, which will affect the normal movement of the moving sub-module 10 on the guide rail 20. The width of the movable gap 500 should also not be too narrow. If the movable gap 500 is too narrow, during the movement of the moving sub-module 10, even if the first roller 200 is not separated from the guide rail 20, the limiting structure 300 may easily touch the guide rail 20, increasing the resistance experienced by the moving sub-module 10.
[0040] When the limiting structure 300 and the frame 100 are detachably connected, multiple limiting structures 300 of different sizes can be prepared in advance. According to the width of the actual compatible guide rail 20, the appropriate size of the limiting structure 300 can be selected to ensure that the size of the movable gap 500 between the limiting structure 300 and the guide rail 20 is maintained between 0.5mm and 1mm.
[0041] In some specific embodiments, the limiting structure 300 can be threadedly connected to the frame 100 via a nut. The frame 100 is provided with a through hole, through which part of the limiting structure 300 passes. The nut is threaded onto the part of the limiting structure 300 that passes through the through hole. By loosening and tightening the nut, the limiting structure 300 can be disassembled and installed.
[0042] The peripheral sidewall of the limiting structure 300 is a working surface 310, which is used for contact with the guide rail 20. When the limiting structure 300 and the guide rail 20 are in a limiting engagement, the working surface 310 and the guide rail 20 are in contact with each other. In some embodiments, refer to... Figure 2 As shown, the working surface 310 can be a cylindrical sidewall structure with a smooth surface without grooves. The guide rail 20 can contact any position of the working surface 310 to achieve a limiting fit between the two.
[0043] In other embodiments, reference is made to Figure 7 As shown, the working surface 310 is provided with a limiting groove 320. When the limiting structure 300 is in a limiting engagement with the guide rail 20 along the width direction of the guide rail 20, the guide rail 20 is engaged with the limiting groove 320. The limiting groove 320 provides limiting on both the upper and lower sides of the guide rail 20, restricting the position of the limiting structure 300 and the guide rail 20 in the direction of gravity, thereby improving the stability of the limiting engagement between the limiting structure 300 and the guide rail 20.
[0044] refer to Figure 1As shown in some embodiments of this application, the frame 100 includes a cantilever section 110 and a connecting section 120 connected in sequence. The cantilever section 110 is suspended above the guide rail 20, and a limiting structure 300 is installed on the cantilever section 110. The cantilever section 110 is above the guide rail 20, which facilitates the installation of the limiting structure 300. Simultaneously, the position sensor 800 of the moving submodule 10 can also be installed on the cantilever section 110. The position sensor 800 cooperates with the position sensor receiving part on the stator module 30 to provide feedback on the position signal of the moving submodule 10.
[0045] In some embodiments, the first roller 200 is also mounted on the cantilever section 110. Both the first roller 200 and the limiting structure 300 are mounted on the cantilever section 110, which facilitates determining the size of the mounting gap 400 between the first roller 200 and the limiting structure 300.
[0046] The connecting section 120 is used for magnetic engagement with the stator module 30 corresponding to the guide rail 20. A portion of the connecting section 120 is bent to form a bent portion 121, see reference. Figures 1 to 4 As shown, the bent connecting section 120 has higher structural strength and can withstand greater pressure. Furthermore, the bent connecting section 120, together with the cantilever section 110, forms an installation space for the first roller 200, making installation of the first roller 200 easier. The bent connecting section 120 also makes it easier to attach to the stator module 30.
[0047] refer to Figures 1 to 4 As shown, the moving module 10 also includes a magnetic plate 600 and a second roller 700. Both the magnetic plate 600 and the second roller 700 are mounted on the frame 100. With the guide rail 20 installed at the mounting gap 400, the magnetic plate 600, the second roller 700, and the first roller 200 are all located on the same side of the guide rail 20. There is an attractive force between the magnetic plate 600 and the stator module 30, causing the moving module 10 and the stator module 30 to move closer together, thus bringing the first roller 200 into contact with the guide rail 20. Furthermore, the first roller 200 and the second roller 700 are located at opposite ends of the magnetic plate 600. The first roller 200 guides the guide rail 20, and the second roller 700 guides the stator module 30. The first roller 200 and the second roller 700, located at opposite ends of the magnetic plate 600, balance the relative positions of the moving module 10, the guide rail 20, and the stator module 30.
[0048] In the case where the frame 100 includes a cantilever section 110 and a connecting section 120, the magnetic plate 600 and the second roller 700 are installed on the connecting section 120 to facilitate cooperation with the stator module 30, and the first roller 200 is installed on the cantilever section 110.
[0049] In some specific implementations, the number of first rollers 200 and second rollers 700 can be greater than one. Two first rollers 200 are arranged side by side, and two second rollers 700 are arranged side by side, which improves the stability of the cooperation between the moving module 10 and the guide rail 20 and the stator module 30.
[0050] The magnetic plate 600 includes a permanent magnet 610 and a magnetically conductive block 620 arranged in an overlapping manner, as shown in the reference. Figure 1 and Figure 2 As shown, the magnetic guide block 620 is located between the permanent magnet 610 and the frame 100. The permanent magnet 610 interacts with the magnetic field generated by the stator module 30, generating a driving force. Furthermore, there is an attractive force between the permanent magnet 610 and the stator module 30, causing the mover module 10 to adhere to the guide rail 20. The magnetic guide block 620 can guide and concentrate the magnetic field generated by the permanent magnet 610, allowing it to be more effectively transmitted to the stator windings, thereby improving the efficiency and performance of the motor.
[0051] refer to Figures 1 to 4 As shown, the circumferential sidewall of the first roller 200 is provided with a clamping groove 210, which is used to clamp the guide rail 20, thereby improving the stability of the fit between the first roller 200 and the guide rail 20.
[0052] Some embodiments of this application also provide a magnetic drive conveying device, see reference. Figure 8 As shown, the system includes the stator module 30 provided in any of the above embodiments. In addition, it includes a mounting bracket 40, a guide rail 20, and a moving module 10. Multiple stator modules 30 are assembled and installed onto the mounting bracket 40 along a preset movement path of the moving module 10. The guide rail 20 is mounted above the stator modules 30, and the moving module 10 is guided and engaged with the guide rail 20. When the stator module 30 is powered on, it drives the moving module 10 to move its position on the guide rail 20.
[0053] The guide rail 20 has a first roller 200 and a limiting structure 300 on each side of the same moving sub-module 10. The limiting structure 300 is used to prevent the moving sub-module 10 from detaching from the guide rail 20.
[0054] It should be noted that, in this document, the terms "comprising," "including," or any other variations thereof are intended to cover non-exclusive inclusion, such that a process, method, article, or apparatus that comprises a list of elements includes not only those elements but also other elements not expressly listed, or elements inherent to such a process, method, article, or apparatus. Unless otherwise specified, an element defined by the phrase "comprising one..." does not exclude the presence of other identical elements in the process, method, article, or apparatus that includes that element.
[0055] The above description is only a specific embodiment of this utility model, but the protection scope of this utility model is not limited thereto. Any changes or substitutions that can be easily conceived by those skilled in the art within the technical scope disclosed in this utility model should be included within the protection scope of this utility model.
