Description

TECHNICAL FIELD

[0001] The utility model relates to intelligent transmission system technical field, especially a magnetic suspension transmission device that can transmit and charge simultaneously. BACKGROUND

[0002] Transmission systems are needed in production lines and article conveying lines. Early transmission systems such as belt transmission and screw rod transmission cannot meet the needs of modern industry. In view of this, magnetic suspension transmission devices are now used in some industries. In a magnetic suspension transmission system, the mover module runs on the stator track and is pushed by electromagnetic force to run at high speed and accurately. For example, see Chinese Utility Model Patent No. 202322746727.1, which discloses a "planar ring-shaped magnetic suspension conveying line". The applicant has been committed to the production and research of magnetic suspension transmission devices and has filed corresponding patent applications. See Utility Model Patent No. 202323139809.6, entitled "Ring Track Transmission System"; Utility Model Patent No. 202323144537.9, entitled "Transmission Track Structure".

[0003] In existing magnetic suspension transmission devices or linear motor transmission systems, the mover module is not only used as a carrier for material transmission, but also carries electric equipment in some industries to perform corresponding operations at set stations. At this time, the mover module itself needs to have power supply capability. To achieve this, the mover module can only be powered by a self-contained energy storage battery or directly by external power supply. However, considering the running speed, running accuracy and running distance of the mover module, direct wire power supply is not practical. If carbon brush slip contact power supply is used, the following problems may arise: the mover module usually runs in an open environment, and its working space is inevitably contaminated with dust and other foreign matter. When carbon brush slip contact power supply is used, direct contact power supply may be affected by dust and other foreign matter in the working space, causing poor contact and even sparking, which seriously affects safety. If the mover module is powered by a self-contained energy storage battery, the energy storage battery has limited capacity and needs to be charged. When charging, the electric equipment on the mover module cannot work, and if it is left on the track, it will affect the normal operation of other mover modules. If the entire mover module is removed for charging, it is too troublesome.

[0039] The utility model is a kind of magnetic suspension transmission device, see Figures 1 to 3 As shown in the figure, the utility model includes: magnetic suspension transmission track 1, magnetic suspension charging track 2, left lifting device 5, right lifting device 6, current collector 7, slide contact charging device 8 and mover carrier 9.

[0040] The magnetic suspension transmission track 1 and the magnetic suspension charging track 2 are arranged in parallel, the magnetic suspension transmission track 1 is located at the upper side, and the magnetic suspension charging track 2 is located at the lower side. The left lifting device 5 and the right lifting device 6 are respectively located at the left and right sides of the magnetic suspension transmission track 1 and the magnetic suspension charging track 2. The mover carrier 9 runs on the tracks of the magnetic suspension transmission track 1 and the magnetic suspension charging track 2 to realize transmission or charging. Meanwhile, the mover carrier 9 is switched between the magnetic suspension transmission track 1 and the magnetic suspension charging track 2 through the left lifting device 5 and the right lifting device 6. The slide contact charging device 8 is parallel to the side of the magnetic suspension charging track 2. When the mover carrier 9 runs on the track of the magnetic suspension charging track 2, the mover carrier 9 can realize the conductive connection between the slide contact charging device 8 through the current collector 7, so as to realize the charging of the mover carrier 9.

[0041] The electromagnetic force driving is adopted between the mover carrier 9 and the magnetic suspension transmission track 1 and the magnetic suspension charging track 2 in the utility model, that is, the stator units for generating magnetic force are uniformly distributed in the tracks of the magnetic suspension transmission track 1 and the magnetic suspension charging track 2, and the Hall element is arranged at the side of each group of stator units to determine the running direction of the mover carrier 9. The stator units generate electromagnetic force under the action of external power source, and the electromagnetic force acts on the magnet in the mover carrier 9 to push the mover carrier 9 to run on the track, so as to realize the running of the mover carrier 9 pushed by the electromagnetic force. The magnetic suspension driving principle and structure are the same as those of the prior art, for example, the existing patent literature in the background art can be referred to, and the utility model will not be described here.

[0042] As shown in the combination Figure 4 The magnetic suspension transmission track 1 is formed by splicing the main track section 10 and the left track section 3 and the right track section 4 located at the two sides of the main track section 10. That is, the main track section 10, the left track section 3 and the right track section 4 are mutually independent stator tracks, and the stator units for generating magnetic force and the related Hall elements are arranged in each track section. In this way, the mover carrier 9 can independently run in the main track section 10, the left track section 3 and the right track section 4.

[0043] As shown in the combination Figure 4 The mover carrier 9 includes a mover base 91, an energy storage unit 92 mounted on the mover base 91, an electric component 93, a control circuit 94 and a mover magnet (not shown in the figure) located below the base 91. The energy storage unit 92 usually adopts a rechargeable battery pack, which is used to supply power to the electric component 93 and the control circuit 94. The electric component 93 is a motor and the like for work, 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, which runs to the specified position and performs related work.

[0044] As shown in the combination Figure 2As shown, the magnetic suspension charging track 2 is equal in length to the main track section 10, and is arranged in parallel below the main track section 10, so as to facilitate the splicing of the left track section 3, the right track section 4, the magnetic suspension charging track 2 and the main track section 10.

[0045] In combination Figure 4 , Figure 13 As shown, in order to realize the stable operation of the mover carrier 9 on the tracks of the magnetic suspension transmission track 1 and the magnetic suspension charging track 2, a track type matching structure is adopted between the mover carrier 9 and the magnetic suspension transmission track 1 and the magnetic suspension charging track 2. Two slide rail sleeves 911 are symmetrically arranged on both sides of the base 91 of the mover carrier 9, and two parallel guide rails 101, 201 of the same specification are arranged on the magnetic suspension transmission track 1 and the magnetic suspension charging track 2. The slide rail sleeve 911 is nested with the guide rail 101, 201, so that the slide rail sleeve 911 can slide along the guide rail 101, 201. Of course, the slide rail sleeve 911 can also adopt a guide wheel.

[0046] The left lifting device 5 and the right lifting device 6 are the same in structure, and are symmetrically distributed on the left and right sides of the main track 1 and the magnetic suspension charging track 2. The left lifting device 5 will be described below.

[0047] The left lifting device 5 comprises a vertical lifting track 51, a longitudinal moving seat 52 matched with the lifting track 51, and a longitudinal moving drive motor 53 driving the longitudinal moving seat 52 to move along the lifting track 51. The lifting track 51 and the longitudinal moving drive motor 53 are fixedly installed on a vertical plate 510 or a vertical column. The left lifting platform 50 is horizontally fixed on the longitudinal moving seat 52. The lifting track 51 and the longitudinal moving seat 52 adopt a structure of slide rail and slide sleeve matching. The longitudinal moving drive motor 53 can drive the longitudinal moving seat 52 to vertically move by adopting a screw drive mechanism, a belt drive mechanism, a chain drive mechanism, etc. The left track section 3 is fixedly installed on the horizontal left lifting platform 50, and moves up and down through the left lifting platform 50, so as to realize the splicing of the left track section 3 with the main track section 10 and the magnetic suspension charging track 2.

[0048] In addition, in order to realize the positioning of the vertical movement of the longitudinal moving seat 52, an inductive element 54 or a positioning element can be added to ensure the accurate positioning of the left track section 3 with the main track section 10 and the magnetic suspension charging track 2. The left track section 3 and the right track section 4 are respectively fixedly installed on the left lifting platform 50 and the right lifting platform 60, and are lifted by the left lifting device 5 and the right lifting device 6, so as to realize the splicing of the left track section 3 and the right track section 4 with the main track section 10 and the magnetic suspension charging track 2 respectively. The right lifting device 6 is the same in structure as the left lifting device 5, and will not be described here.

[0049] 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.

[0050] 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.

[0051] 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.

[0052] 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.

[0053] Of course, in order not to affect the normal operation, the transverse module 11 is provided with two groups of parallel main track sections 10, and the two groups of parallel main track sections 10 can be switched by the transverse module 11 to realize the butt joint with the maglev transmission track 1. In this way, when the current main track section 10 fails or the mover carrier 9 needs to work at this position, another main track section 10 can be switched by the transverse module 11, so as to ensure that the whole system can continue to operate.

[0054] For the convenience of description, as shown in Figure 1 , Figure 2 in the specific embodiment, Figure 1 the lateral direction is the X axis, the longitudinal direction is the Y axis, Figure 2 the lateral direction is the Z axis. The mover carrier 9 moves along the maglev transmission track 1 or the maglev charging track 2 to realize movement along the X axis. The left lifting device 5 and the right lifting device 6 can drive the mover carrier 9 to realize movement along the Y axis. The main track section 10 is fixed on the transverse seat 112 to realize movement of the whole main track section 10 along the Z axis.

[0055] As shown in Figures 8 to 13 , the slide charging device 8 is arranged in parallel beside the maglev charging track 2, which has a conductive strip 80 for providing charging power. When the mover carrier 9 moves on the maglev charging track 2, the energy storage unit 92 is charged by the collector 7 and the conductive strip 80. Specifically, the slide charging device 8 includes a conductive strip 80, a conductive groove 81, a conductive groove fixing seat 82, and a fixing plate 83. The fixing plate 83 is a fixed bearing part, which is arranged in parallel beside the maglev charging track 2 in a vertical state. Two parallel conductive grooves 81 are fixed inside the fixing plate 83 by the conductive groove fixing seat 82. The conductive groove fixing seat 82 adopts a clamping fixing structure, and the whole conductive groove 81 is fixed on the fixing plate 83 by a plurality of conductive groove fixing seats 82. The conductive groove 81 is usually made of ceramic or other insulating materials, which has a V-shaped or similar groove, and the conductive strip 80 is fixed in the conductive groove 81. The conductive strip 80 is usually made of copper strip. The conductive strips 80 in the two conductive grooves 81 respectively serve as the positive and negative poles of the power supply, and are connected to the external power supply by wires 84, thereby forming a charging electrode.

[0056] As shown in Figures 13 to 17As shown, the current collector 7 includes a substrate 71 and two sets of conductive sliding contact units 70 mounted on the substrate 71. The substrate 71 is connected to the mover base 91 through a connecting plate 72, which can be fixed by screws. Of course, in order to achieve quick fitting, the connecting plate 72 can be connected by clamping, strong magnetic adsorption, etc. When the mover carrier 9 is transported to the magnetic levitation charging track 2, the mover carrier 9 is connected to the current collector 7 through the connecting plate 72, and the charging connection line of the energy storage unit 92 in the mover carrier 9 is connected to the conductive brushes of the two conductive sliding contact units 70 through wires, and the charging operation is waited.

[0057] The conductive sliding contact unit 70 has a conductive brush 73 connected to the substrate 71 through an elastic movable linkage mechanism, and the energy storage unit 92 is connected to the conductive brush 73 through wires. The elastic movable linkage mechanism can overcome the adverse conditions such as jumping and displacement deviation during operation, and ensure that the conductive brush 73 is stably connected to the conductive strip 80 in the sliding contact charging device 8.

[0058] Specifically, the two conductive sliding contact units 70 are horizontally and parallelly arranged on the outer side of the substrate 71, and each conductive sliding contact unit 70 includes a conductive brush 73, a connecting pin 74, a swing arm 75 and a connecting seat 76. The connecting seat 76 is fixed to the outer side of the substrate 71 through connecting bolts 77, and the connecting bolts 77 are also used as components connected to the connecting plate 72, and the connecting plate 72 is fixed to the substrate 71 through the cooperation of the nuts and the connecting bolts 77.

[0059] One side of the connecting seat 76 is formed with a pair of ear plates, and the swing arm 75 is elastically pivoted between the two ear plates of the connecting seat 76 to realize swinging along the pivoting position 750. One end of the swing arm 75 is provided with a limiting plate 752, and the other end is used to connect with the connecting pin 74. The limiting plate 752 is used to limit the swinging amplitude of the swing arm 75, and a wire positioning ring 753 is arranged outside the limiting plate 752 to pass the charging connection line connecting the energy storage unit 92 and the conductive brush 73, so as to realize the positioning of the charging connection line.

[0060] A compression spring 751 is arranged between the swing arm 75 and the connecting seat 76, and a certain elastic force is applied to the swing arm 75 through the compression spring 751, so that the end connected with the connecting pin 74 has a tendency to run to the sliding contact charging device 8. The compression spring 751 is installed in the following manner: a receiving groove capable of cooperating with both ends of the compression spring 751 is arranged in the inner side of the connecting seat 76 and the middle of the swing arm 75, and both ends of the compression spring 751 are limited through the receiving grooves.

[0061] One end of the swing arm 75 connected with the connecting pin 74 is formed with a pin hole 754, and the upper end of the pin hole 754 is a wedge-shaped groove 755.

[0062] The connecting pin 74 is sleeved with a compression spring 741. One end of the connecting pin 74 is formed with a limiting end cap 742, and the other end is provided with a pivoting part 743 connected with the conductive brush 73. The limiting end cap 742 is wedge-shaped and matched with the groove 755, and the connecting pin 74 is in sliding fit with the pin hole 754. Under the elastic force of the compression spring 741, the limiting end cap 742 is pressed in the groove 755, and since the limiting end cap 742 and the groove 755 are in wedge-shaped nested fit, the connecting pin 74 can be quickly reset even if it rotates along the axis.

[0063] The conductive brush 73 is generally a carbon brush, and the conductive brush 73 is fixed on the brush holder 731. The brush holder 731 has a pivoting part 743 and a wiring slot 732 for connecting the charging connection line. The charging connection line for connecting the energy storage unit 92 and the conductive brush 73 is finally connected to the wiring slot 732, so that the entire charging circuit is turned on.

[0064] The utility model discloses a current collector 7 realizes stable conductive contact, thereby making the energy storage unit 92 be connected with the conductive brush 73 through the wire, and can overcome the bad situation such as jumping and displacement deviation in the operation process, and ensure that the conductive brush 73 is stably connected with the conductive strip 80 in the slide contact charging device 8.

[0065] Through the above, the charging and discharging method of the mover carrier 9 in the utility model is: the mover carrier is driven by the magnetic force of the stator unit and the mover magnet, and runs along the magnetic suspension transmission track, realizes the transmission of the mover carrier, and in the process, the energy storage unit is discharged to supply power for the electrical equipment carried on the mover carrier. When charging, first, the mover carrier 9 runs to the left track section 3 position, and is lowered to the same level position with the magnetic suspension charging track 2 through the left lifting device 5;

[0066] Secondly, the mover carrier 9 is connected with the current collector 7, the synchronous operation of the mover carrier 9 and the current collector 7 is realized, the conductive brush 73 of the current collector 7 is connected with the energy storage unit 92 through the charging wire, the slide contact connection with the conductive strip 80 is realized, and the energy storage unit 92 is charged.

[0067] Then, the mover carrier 9 runs to the right track section 4 direction under the drive of the magnetic suspension charging track 2 at the same time or after the charging is completed, and runs to the right track section 4 on which the right lifting device 6 has been lowered.

[0068] Finally, the current collector 7 is separated from the mover carrier 9, the circuit between the energy storage unit 92 and the current collector 7 is disconnected, the mover carrier 9 is lifted along the right track section 4 under the driving of the right lifting device 6, the right track section 4 is spliced with the main track section 10 again, the charged mover carrier 9 returns to the magnetic levitation transmission track 1 again, corresponding transmission operation is carried out, and the energy storage unit 92 supplies power for the self-provided electric component 93 during the transmission operation, so that the energy storage unit 92 is realized.
