Description

Technical field:

[0001] The utility model relates to the technical field of intelligent transmission systems, in particular to a magnetic suspension transmission device capable of performing transmission and charging simultaneously. Background technology:

[0002] Production lines and conveyor belts require transmission systems. Earlier transmission systems, such as belts and screws, are no longer able to meet modern industrial needs. To address this, some industries are now using magnetic levitation transmission systems. In a magnetic levitation transmission system, a mover module runs on a stator track, propelled by electromagnetic force for high-speed and accurate movement. For example, see Chinese Utility Model Patent No. 202322746727.1, which discloses a "planar annular magnetic levitation conveyor line." The applicant has been dedicated to the production and research and development of magnetic levitation transmission systems and has filed corresponding patent applications. See Patent No. 202323139809.6, entitled "A Circular Track Transmission System," and Patent No. 202323144537.9, entitled "A Transmission Track Structure."

[0003] In existing magnetic levitation transmission devices or linear motor transmission systems, the mover module serves not only as a carrier for material transport but, in some industries, also carries electric equipment to perform tasks at designated workstations. This necessitates the mover module's own power supply. This capability can only be achieved through internal energy storage batteries or direct external power supply. However, considering the operating speed, accuracy, and range of the mover module, direct power supply via wires is impractical. Using carbon brushes for power supply presents the following challenges: Mover modules typically operate in open environments, where dust and other foreign matter are unavoidable. Using carbon brushes for power supply, due to direct contact, can be susceptible to interference from dust and other foreign matter, leading to poor contact and even sparks, which can seriously impact safety. If the mover module is powered by its own energy storage battery, the battery's capacity is limited and requires charging. During charging, the electric equipment on the mover module becomes inoperable. If the battery remains on track, it can affect the normal operation of other mover modules. It would be too troublesome to remove the entire actuator module for charging.

[0004] In view of the above problems, the inventors of the present utility model have proposed the following technical solutions through continuous improvements. Utility model content:

[0005] The technical problem to be solved by the present invention is to overcome the deficiencies of the prior art and provide a double-layer magnetic levitation transmission device, which can realize the simultaneous transmission and charging operations of multiple mover carriers through the magnetic levitation transmission track and magnetic levitation charging track distributed above and below.

[0006] In order to solve the above technical problems, the present invention adopts the following technical solutions: a double-layer magnetic levitation transmission device, which includes: a magnetic levitation transmission track, a magnetic levitation charging track, a left lifting device, a right lifting device and a mover carrier; the magnetic levitation transmission track is formed by splicing a mutually independent main track segment and a left track segment and a right track segment located on both sides of the main track segment, and a stator unit for generating magnetic force is respectively provided in the main track segment, the left track segment and the right track segment; the mover carrier includes: a mover base, an energy storage unit installed on the mover base and a mover magnet, and the magnetic force generated by the stator unit and the mover magnet are connected The magnetic levitation charging track is equal in length to the main track segment and is arranged parallel to and below the main track segment. A stator unit for generating magnetic force is arranged in the magnetic levitation charging track. The left lifting device and the right lifting device are respectively located vertically at the left and right ends of the main track segment. The left track segment and the right track segment are respectively fixedly mounted on the left lifting device and the right lifting device. The left track segment and the right track segment are driven to rise and fall by the left lifting device and the right lifting device, thereby realizing the splicing of the left track segment and the right track segment with the main track segment and the magnetic levitation charging track respectively.

[0007] Furthermore, in the above technical solution, the left lifting device and the right lifting device respectively have a left lifting platform and a right lifting platform that can be lifted and lowered in the Y-axis direction, and the left track segment and the right track segment are respectively fixedly installed on the left lifting platform and the right lifting platform.

[0008] Furthermore, in the above technical solution, the left lifting device includes: a vertically set lifting track, a longitudinal movement seat cooperating with the lifting track, and a longitudinal movement drive motor driving the longitudinal movement seat to move along the lifting track, and the left lifting platform is horizontally fixed on the longitudinal movement seat.

[0009] Furthermore, in the above technical solution, the lifting rail and the longitudinal drive motor are fixedly installed on the vertical plate or the column, and a sensing element for positioning is provided between the vertical seat and the vertical plate.

[0010] Furthermore, in the above technical solution, a structure in which a slide rail and a slide sleeve cooperate is adopted between the lifting track and the longitudinal movement seat.

[0011] Furthermore, in the above technical solution, the lifting and longitudinal movement drive motor adopts a screw drive mechanism, a belt drive mechanism, or a chain drive mechanism to drive the longitudinal movement seat to move vertically.

[0012] Furthermore, in the above technical solution, the right lifting device and the left lifting device have the same structure, and the right lifting device and the left lifting device are symmetrically distributed at the left and right ends of the main track section.

[0013] Furthermore, in the above technical solution, the main track segment is installed on the transverse movement module, and the main track segment is moved in the Z-axis direction through the transverse movement module.

[0014] Furthermore, in the above technical solution, the transverse movement module includes: a transverse movement track distributed perpendicularly to the main track segment, a transverse movement seat cooperating with the transverse movement track, and a transverse movement drive motor driving the transverse movement seat to run along the transverse movement track. Two sets of parallel main track segments are installed on the transverse movement module to realize position switching in the Z-axis direction.

[0015] After adopting the above technical solution, the present invention has the following beneficial effects compared with the existing technology: the present invention is provided with a magnetic levitation charging track parallel to the magnetic levitation transmission floating track used for transmission, and the mover carrier realizes displacement transmission through the magnetic levitation transmission floating track. When the mover carrier needs to be charged, it is switched to the magnetic levitation charging track through the left and right lifting devices. In this way, it does not affect the normal operation of the upper magnetic levitation transmission track, and can complete the charging operation of the mover carrier that lacks power, thereby further improving the working efficiency of the magnetic levitation transmission device.

[0016] The utility model can realize charging of the mover carrier while it is moving through the magnetic suspension transmission floating track, and realize the return of the mover carrier without affecting other mover carriers that are in operation.

[0017] 3. The magnetic levitation charging track of the utility model is located below the magnetic levitation transmission floating track. In this way, when the equipment is installed, the magnetic levitation charging track can be installed relatively closed inside the equipment shell. The entire charging operation is in a relatively closed space, reducing charging interference and improving charging safety.

[0026] Figure 8 It is a three-dimensional diagram of the utility model in use. Specific implementation method:

[0027] The utility model is a double-layer magnetic suspension transmission device. Figures 1 to 3 As shown, the utility model includes: a magnetic levitation transmission track 1, a magnetic levitation charging track 2, a left lifting device 5, a right lifting device 6 and a mover carrier 9.

[0028] The magnetic levitation transmission track 1 and the magnetic levitation charging track 2 are arranged in parallel up and down, with the magnetic levitation transmission track 1 located at the top and the magnetic levitation charging track 2 located at the bottom. The left lifting device 5 and the right lifting device 6 are located on the left and right sides of the magnetic levitation transmission track 1 and the magnetic levitation charging track 2, respectively. The mover carrier 9 runs on the tracks of the magnetic levitation transmission track 1 and the magnetic levitation charging track 2 to achieve transmission or charging. At the same time, the left lifting device 5 and the right lifting device 6 are used to switch between the magnetic levitation transmission track 1 and the magnetic levitation charging track 2. When the mover carrier 9 runs on the track of the magnetic levitation charging track 2, the mover carrier 9 can be connected to an external power supply to complete charging.

[0029] The drive between the mover carrier 9 and the magnetic levitation transmission track 1 and the magnetic levitation charging track 2 in this utility model is electromagnetic. Specifically, magnetic stator units are evenly distributed along the tracks of the magnetic levitation transmission track 1 and the magnetic levitation charging track 2. Hall elements are positioned adjacent to each set of stator units to determine the direction of movement of the mover carrier 9. Under the action of an external power source, the stator units generate electromagnetic force, which interacts with the magnets in the mover carrier 9 to propel the mover carrier 9 along the tracks, achieving electromagnetic propulsion of the mover carrier 9. The principle and structure of this magnetic levitation drive are identical to those of the prior art. For example, reference may be made to the existing patent literature in the background art, and this utility model will not be elaborated upon.

[0030] Combine Figure 4As shown, the magnetic levitation transmission track 1 is composed of a mutually independent main track segment 10 and two flanking left and right track segments 3 and 4. Specifically, the main track segment 10, the left track segment 3, and the right track segment 4 form independently constructed stator tracks, each containing a stator unit for generating magnetic force and associated Hall effect elements. This allows the mover carrier 9 to operate independently on the main track segment 10, the left track segment 3, and the right track segment 4.

[0031] Combine Figure 4 As shown, the mover carrier 9 includes: a mover base 91, an energy storage unit 92 installed on the mover base 91, an electric component 93, a control circuit 94, and a mover magnet located below the base 91 (not shown). The energy storage unit 92 usually adopts a rechargeable battery pack, which is used to power the electric component 93 and the control circuit 94. The electric component 93 is a working motor and other components, and the control circuit 94 can be a control circuit with a built-in communication module to realize remote control of the electric component 93. In this way, the mover carrier 9 can be used as a mobile workstation, and after running to the designated position, it can perform related operations.

[0032] Combine Figure 2 As shown, the magnetic levitation charging track 2 is the same length as the main track segment 10, and is arranged parallel to the bottom of the main track segment 10. This is to facilitate the splicing and combination of the left track segment 3, the right track segment 4, the magnetic levitation charging track 2 and the main track segment 10.

[0033] Combine Figure 4 As shown, to ensure stable operation of the mover carrier 9 on the magnetic levitation transmission track 1 and the magnetic levitation charging track 2, a track-type matching structure is adopted between the mover carrier 9, the magnetic levitation transmission track 1 and the magnetic levitation charging track 2. Slide rail sleeves 911 are symmetrically arranged on both sides of the base 91 of the mover carrier 9. Two parallel guide rails 101 of the same specifications are provided on each of the magnetic levitation transmission track 1 and the magnetic levitation charging track 2. The slide rail sleeves 911 nest with the guide rails 101, allowing the slide rail sleeves 911 to slide along the guide rails 101. Of course, the slide rail sleeves 911 can also be equipped with guide wheels.

[0034] The left lifting device 5 and the right lifting device 6 have the same structure and are symmetrically distributed on the left and right sides of the main track 1 and the magnetic levitation charging track 2. The left lifting device 5 is described below.

[0035] The left lifting device 5 includes: a vertically established lifting rail 51, a longitudinal movement seat 52 cooperating with the lifting rail 51, and a longitudinal movement drive motor 53 that drives the longitudinal movement seat 52 to run along the lifting rail 51. The lifting rail 51 and the longitudinal movement drive motor 53 are fixedly mounted on the vertical plate 510 or the column. The left lifting platform 50 is horizontally fixed on the longitudinal movement seat 52. A structure of sliding rails and sliding sleeves is adopted between the lifting rail 51 and the longitudinal movement seat 52. The longitudinal movement drive motor 53 can use a screw drive mechanism, a belt drive mechanism, a chain drive mechanism, etc. to drive the longitudinal movement seat 52 to run vertically. The left track segment 3 is fixedly mounted on the horizontal left lifting platform 50, and the left lifting platform 50 moves up and down to realize the splicing of the left track segment 3 with the main track segment 10 and the magnetic levitation charging track 2.

[0036] In addition, to achieve vertical positioning of the longitudinal displacement seat 52, an induction element 54 or a positioning element can be added to ensure accurate alignment of the left track segment 3 with the main track segment 10 and the magnetic levitation charging track 2. The left track segment 3 and the right track segment 4 are fixedly mounted on the left lifting platform 50 and the right lifting platform 60, respectively. The left and right track segments 3 and 4 are raised and lowered by the left and right lifting devices 5 and 6, respectively, to achieve splicing of the left and right track segments 3 and 4 with the main track segment 10 and the magnetic levitation charging track 2, respectively. The right lifting device 6 has the same structure as the left lifting device 5 and will not be described in detail here.

[0037] From the above description, it can be seen that in the present invention, the magnetic levitation charging track 2 is located below the magnetic levitation transmission track 1. This ensures the normal operation of the upper magnetic levitation transmission track 1 while completing the charging operation of the power-deficient mover carrier 9, further improving the working efficiency of the magnetic levitation transmission device. For example, when it is found that a mover carrier 9 running on the magnetic levitation transmission track 1 is running low on power and needs to be charged, the mover carrier 9 is moved to the left track segment 3, and then the left lifting device 5 is lowered to separate the left track segment 3 from the main track segment 10 and spliced with the magnetic levitation charging track 2. Then, the mover carrier 9 is pushed onto the magnetic levitation charging track 2 for charging. After charging is completed, it is raised by the right lifting device 4 and returns to the magnetic levitation transmission track 1 to continue the operation. At the same time, the magnetic levitation charging track 2 is located below the magnetic levitation transmission floating track 1. In this way, when the equipment is installed, the magnetic levitation charging track 2 can be relatively closed and installed inside the equipment shell. The entire charging operation is in a relatively closed space, reducing charging interference and improving charging safety.

[0038] The structure described above enables the normal operation and charging of the mover carrier 9 in the present invention. However, at certain times, a section of the main track segment 10 may malfunction and require maintenance. In this case, the entire system must be stopped, causing the entire system to be unable to operate. In addition, in some operating scenarios, the mover carrier 9 may need to stop at a certain position to operate. At this time, the stopped mover carrier 9 will affect the normal operation of other mover carriers 9, and avoidance is required. For this purpose, the present invention is provided with a transverse movement module 11.

[0039] See Figure 5 、 Figure 6 、 Figure 7 As shown, a certain main track segment 10 in the present invention can be installed on a transverse module 11. The transverse module 11 includes: a transverse track 111 distributed perpendicularly along the horizontal plane with the main track segment 10, a transverse seat 112 cooperating with the transverse track 111, and a transverse drive motor 113 driving the transverse seat 112 to move along the transverse track 111.

[0040] The transverse rail 111 is fixedly mounted on a transverse fixing plate 110, and the transverse fixing plate 110 is used to realize the positioning of the entire transverse module 11 in the entire system. The main rail segment 10 is fixed on a transverse seat 112 to realize overall movement in the horizontal direction. In this embodiment, the main rail segment 10 is mounted on two parallel transverse rails 111, and the transverse seat 112 and the transverse rail 111 are usually matched with a slide rail and a sliding sleeve. The transverse drive motor 113 can use a screw drive mechanism, a belt drive mechanism, a chain drive mechanism, etc. to drive the transverse seat 112 to move horizontally, thereby realizing the separation of the main rail segment 10 from the original magnetic levitation transmission track 1.

[0041] Of course, to ensure normal operation is not affected, the transverse module 11 is equipped with two sets of parallel main track segments 10. These two sets of parallel main track segments 10 can be switched through the transverse module 11 to achieve docking with the magnetic levitation transmission track 1. In this way, if the current main track segment 10 fails or the mover carrier 9 needs to operate at that location, the transverse module 11 can be used to switch to another main track segment 10, thus ensuring the continuous operation of the entire system.

[0042] For ease of explanation, combined Figure 1 、 Figure 2 As shown, in this specific embodiment, Figure 1 The horizontal direction is the X axis, and the vertical direction is the Y axis. Figure 2The horizontal direction in the figure is the Z-axis. The movable carrier 9 moves along the magnetic levitation transmission track 1 or the magnetic levitation charging track 2 along the X-axis. The left and right lifting devices 5 and 6 can drive the movable carrier 9 to move along the Y-axis. The main track segment 10 is fixed to the transverse movement seat 112, enabling movement of the entire main track segment 10 along the Z-axis.

[0043] In the present invention, when the mover carrier 9 is performing charging operation on the magnetic suspension charging track 2, Figure 1 、 Figure 3 As shown, it can be charged using a sliding contact method, that is, charging is achieved by connecting the current collector 7 and the sliding contact charging device 8. During installation, the sliding contact charging device 8 is placed parallel to the side of the magnetic levitation charging track 2. When the mover carrier 9 runs on the magnetic levitation charging track 2, the energy storage unit 92 is connected to the conductive strips in the sliding contact charging device 8 through the current collector 7, charging the energy storage unit 92. Of course, direct charging can also be performed using a charging cable.

[0044] See Figure 8 This is a three-dimensional view of the present invention in use. In actual use, the present invention is mounted on a machine base 11a. The magnetic levitation transmission track 1, magnetic levitation charging track 2, left lifting device 5, and right lifting device 6 are assembled using profiles to form a magnetic levitation transmission unit 1a. Several magnetic levitation transmission units 1a can be combined to form a magnetic levitation transmission line.

[0045] Of course, the above description is only a specific embodiment of the present invention and is not intended to limit the scope of implementation of the present invention. Any equivalent changes or modifications made based on the structure, features and principles described in the scope of the patent application of the present invention should be included in the scope of the patent application of the present invention.
