Description

Technical field:

[0001] The present invention relates to the technical field of intelligent transmission systems, and in particular to a magnetic suspension transmission system and a charging and discharging method thereof. Background technology:

[0002] Transmission systems are required on production lines and item conveyor lines. The early transmission systems such as belt transmission and screw transmission can no longer meet the needs of modern industry. In response to this, magnetic levitation transmission systems are currently being used in some industries. In the magnetic levitation transmission system, the mover module runs on the stator track, and the electromagnetic force drives the mover module to run at high speed and accurately. For example, see the Chinese utility model patent with patent number: 202322746727.1, which discloses "a planar annular magnetic levitation conveyor line". The applicant has been committed to the production and development of magnetic levitation transmission systems and has filed corresponding patent applications. See patent number: 202323139809.6, title: A utility model patent for an annular track transmission system; patent number: 202323144537.9, title: A utility model patent for a transmission track structure.

[0003] In the existing magnetic levitation transmission system or linear motor transmission system, the mover module is not only used as a carrier for material transmission. In some industries, the mover module is also equipped with electric equipment to perform corresponding operations at the set workstation. At this time, the mover module itself needs to have power supply capability. To achieve the power supply capability of the mover module itself, it can only be achieved through its own energy storage battery or direct external power supply. However, considering the running speed, running accuracy and running distance of the mover module, it is unrealistic to directly use wire power supply. If the carbon brush sliding contact is used for power supply, the following problems will arise: the mover module is usually transmitted and operated in an open environment, and its working space will inevitably have foreign matter such as dust. When the carbon brush sliding contact is used for power supply, it is directly contacted. It may be interfered by foreign matter such as dust in the working space, resulting in poor contact, or even sparks and other factors that seriously affect safety. If the mover module is powered by its own energy storage battery, the energy storage battery has limited power and needs to be charged. During charging, the electric equipment on the mover module cannot work. If it is still kept on the track, it will 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 have proposed the following technical solutions through continuous improvements. Summary of the invention:

[0005] The first technical problem to be solved by the present invention is to overcome the deficiencies of the prior art and provide a magnetic levitation transmission system.

When the movable carrier runs on the magnetic levitation charging track, the energy storage unit is connected to the conductive strip by sliding contact through the collector to charge the energy storage unit.

[0008] Furthermore, in the above technical solution, guide rails of the same specifications are arranged on the magnetic levitation transmission track and the magnetic levitation charging track; and a guide seat or guide wheel matching the guide rails is arranged at the lower end of the mover base.

[0009] The main track segment is installed on the transverse movement module, and the transverse movement module includes: a transverse movement track vertically distributed with the main track segment, a transverse movement seat matched with the transverse movement track, and a transverse movement drive motor driving the transverse movement seat to move along the transverse movement track. The main track segment is fixed on the transverse movement seat to realize movement in the Z-axis direction.

[0010] Furthermore, in the above technical solution, two sets of parallel main track segments are installed on the transverse movement module.

[0011] Furthermore, in the above technical solution, the left lifting device includes: a vertically set lifting track, a longitudinal shift seat cooperating with the lifting track, and a longitudinal drive motor driving the longitudinal shift seat to move along the lifting track, and the left lifting platform is horizontally fixed on the longitudinal shift seat.

[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 collector includes: a substrate and two groups of conductive sliding contact units installed on the substrate, the substrate is connected to the mover base through a connecting plate, the conductive sliding contact unit has a conductive brush connected to the substrate through an elastic movable connecting rod mechanism, and the energy storage unit is connected to the conductive brush through a wire.

[0014] Furthermore, in the above technical solution, the sliding contact charging device includes: two parallel conductive strips, a conductive slot and a conductive slot fixing seat corresponding to the two groups of conductive sliding contact units, the conductive strip is fixed in the conductive slot and is connected to an external power supply, and the conductive slot is fixed to a fixed plate through a conductive slot fixing seat; the conductive brush is elastically pressed in the conductive slot and is in conductive contact with the conductive strip.

[0015] Furthermore, in the above technical solution, the conductive sliding contact unit includes: a conductive brush, a connecting pin, a swing arm and a connecting seat, the swing arm is elastically pivoted to the connecting seat, the swing end of the swing arm is connected to the connecting pin through a sliding fit in the shaft hole, and a compression spring is sleeved on the connecting pin; the conductive brush is pivoted to the end of the connecting pin.

[0016] In order to solve the above-mentioned second technical problem, the present invention adopts the following technical solutions: a charging and discharging method of a magnetic levitation transmission system, wherein the charging and discharging method is as follows: the mover carrier generates magnetic force through the stator unit and acts on the mover magnet, runs along the magnetic levitation transmission track, realizes the transmission of the mover carrier, and discharges through the energy storage unit during the passage process to power the electrical equipment carried on the mover carrier; when charging, first, the mover carrier runs to the left track segment position, and descends to the position flush with the magnetic levitation charging track through the left lifting device; secondly, the energy storage unit on the mover carrier is connected to the conductive strip sliding contact through the collector to realize charging of the energy storage unit; then, while charging or after charging is completed, the mover carrier runs in the direction of the right track segment under the drive of the magnetic levitation charging track until it runs to the right track segment that has already descended with the right lifting device; finally, the energy storage unit is disconnected from the collector, and the mover carrier rises with the right track segment under the drive of the right lifting device, so that the right track segment is spliced ​​with the main track segment again.

[0017] After adopting the above technical solution, the present invention has the following beneficial effects compared with the prior art:

[0018] 1. In the magnetic levitation transmission system of the present invention, a magnetic levitation charging track is arranged parallel to the magnetic levitation transmission track used for transmission. The mover carrier realizes displacement transmission through the magnetic levitation transmission 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 system.

[0019] 2. The magnetic levitation charging track of the present invention 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, which prevents the sliding contact charging device from contacting foreign matter such as dust in the open space during the charging operation, reduces charging interference, and improves charging safety.

[0020] 3. The mover carrier in the present invention has its own energy storage unit, which directly powers the relevant electric equipment on the mover carrier, further improving the use function of the present invention, and can be applied in more work scenarios and has a wider range of uses.

[0040] The present invention is a magnetic suspension transmission system. Figures 1 to 3 As shown, the present invention includes: a magnetic suspension transmission track 1, a magnetic suspension charging track 2, a left lifting device 5, a right lifting device 6, a current collector 7, a sliding contact charging device 8 and a mover carrier 9.

[0041] 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. The sliding contact charging device 8 is located parallel to the side of 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 achieve conductive connection with the sliding contact charging device 8 through the collector 7, thereby realizing the charging of the mover carrier 9.

[0042] The drive between the mover carrier 9 and the magnetic suspension transmission track 1 and the magnetic suspension charging track 2 in the present invention is driven by electromagnetic force, that is, stator units that generate magnetic force are evenly distributed in the tracks of the magnetic suspension transmission track 1 and the magnetic suspension charging track 2, and Hall elements are set beside each group of stator units to determine the running direction of the mover carrier 9. The stator unit generates electromagnetic force under the action of an external power supply, and acts with the magnet in the mover carrier 9 to push the mover carrier 9 to run on the track, realizing the operation of the mover carrier 9 driven by electromagnetic force. The principle and structure of the magnetic suspension drive are the same as those of the prior art. For example, the existing patent documents in the background technology can be referred to, and the present invention will not repeat them.

[0043] Combination Figure 4 As shown, the magnetic suspension transmission track 1 is formed by splicing the main track segment 10, which is independent of each other, and the left track segment 3 and the right track segment 4 located on both sides of the main track segment 10. That is, the main track segment 10, the left track segment 3 and the right track segment 4 are stator tracks that are independently completed, and each track segment is respectively provided with a stator unit for generating magnetic force and a related Hall element. In this way, the mover carrier 9 can operate independently on the main track segment 10, the left track segment 3 and the right track segment 4.

[0044] Combination 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.

[0045] Combination Figure 2 As shown, the magnetic levitation charging track 2 is of the same length as the main track segment 10 and is arranged parallel to and below the main track segment 10 , so as 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 .

[0046] Combination Figure 4 , Fig.13As shown, in order to achieve stable operation of the mover carrier 9 on the tracks of 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 and 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, and two parallel guide rails 101 and 201 of the same specifications are arranged on the magnetic levitation transmission track 1 and the magnetic levitation charging track 2. The slide rail sleeves 911 are nested with the guide rails 101 and 201, so that the slide rail sleeves 911 can slide along the guide rails 101 and 201. Of course, the slide rail sleeves 911 can also use guide wheels.

[0047] 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 suspension charging track 2. The left lifting device 5 is used for explanation below.

[0048] The left lifting device 5 includes: a vertically set lifting track 51, a longitudinal shift seat 52 matched with the lifting track 51, and a longitudinal shift drive motor 53 that drives the longitudinal shift seat 52 to run along the lifting track 51. The lifting track 51 and the longitudinal shift 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 shift seat 52. A structure in which a slide rail and a slide sleeve cooperate is adopted between the lifting track 51 and the longitudinal shift seat 52. The longitudinal shift drive motor 53 can use a screw drive mechanism, a belt drive mechanism, a chain drive mechanism, etc. to drive the longitudinal shift 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.

[0049] In addition, in order to realize the positioning of the vertical movement of the longitudinal displacement seat 52, an induction element 54 or a positioning element can be added to ensure the 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, and the left track segment 3 and the right track segment 4 are lifted and lowered by the left lifting device 5 and the right lifting device 6, so as to realize the splicing of the left track segment 3 and the right track segment 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, which will not be described here.

[0050] From the above, it can be seen that in the present invention, the magnetic suspension charging track 2 is located below the magnetic suspension transmission track 1, so that while ensuring the normal operation of the upper magnetic suspension transmission track 1, the charging operation of the power-deficient mover carrier 9 can be completed, further improving the working efficiency of the magnetic suspension transmission system. For example, when it is found that a mover carrier 9 running on the magnetic suspension transmission track 1 is insufficient in 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 suspension charging track 2, and then the mover carrier 9 is pushed to the magnetic suspension charging track 2 for charging, and after the charging is completed. After rising through the right lifting device 4, it returns to the magnetic suspension transmission track 1 and continues to operate. At the same time, the magnetic suspension charging track 2 is located below the magnetic suspension transmission floating track 1, so that when the equipment is installed, the magnetic suspension charging track 2 can be relatively closed and installed inside the equipment housing, and the entire charging operation is in a relatively closed space, reducing charging interference and improving charging safety.

[0051] The structure described above realizes the normal operation and charging operation of the mover carrier 9 in the present invention. However, in certain specific periods, a certain section of the main track section 10 may fail and need maintenance. At this time, the entire system must be stopped, causing the entire system to be unable to operate. In addition, in some operation 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 subsequent mover carriers 9, and avoidance is required at this time. For this reason, the present invention is provided with a transverse movement module 11.

[0052] 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 vertically distributed along the horizontal plane with the main track segment 10, a transverse seat 112 matched with the transverse track 111, and a transverse drive motor 113 driving the transverse seat 112 to run along the transverse track 111.

[0053] The transverse track 111 is fixedly mounted on the transverse fixing plate 110, and the positioning of the entire transverse module 11 in the entire system is achieved through the transverse fixing plate 110. The main track segment 10 is fixed on the transverse seat 112 to achieve overall movement in the horizontal direction. In this embodiment, the main track segment 10 is installed on two parallel transverse tracks 111, and the transverse seat 112 and the transverse track 111 are usually matched with a slide rail and a slide 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 track segment 10 from the original magnetic levitation transmission track 1.

[0054] Of course, in order not to affect normal operation, two sets of parallel main track segments 10 are installed on the transverse module 11, and these two sets of parallel main track segments 10 can be switched through the transverse module 11 to achieve docking with the magnetic suspension transmission track 1. In this way, when the current main track segment 10 fails, or the mover carrier 9 needs to operate at this position, another main track segment 10 can be switched through the transverse module 11, thereby ensuring that the entire system can continue to operate.

[0055] For the sake of explanation, 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 2 The horizontal direction in the figure is the Z axis. The mover carrier 9 moves along the magnetic suspension transmission track 1 or the magnetic suspension charging track 2 along the X axis. The left lifting device 5 and the right lifting device 6 can drive the mover carrier 9 to move along the Y axis. The main track segment 10 is fixed on the transverse shift seat 112 to achieve movement of the entire main track segment 10 along the Z axis.

[0056] See Figures 8 to 13 As shown, the sliding contact charging device 8 is arranged in parallel on the side of the magnetic suspension charging track 2, and has a conductive bar 80 that provides charging power. When the movable carrier 9 runs on the magnetic suspension charging track 2, the energy storage unit 92 is connected to the conductive bar 80 by sliding contact through the collector 7 to charge the energy storage unit 92. Specifically, the sliding contact charging device 8 includes: a conductive bar 80, a conductive slot 81, a conductive slot fixing seat 82, and a fixing plate 83. The fixing plate 83 is a fixed bearing component, which is arranged in parallel on the side of the magnetic suspension charging track 2 in a vertical state. Two parallel conductive slots 81 are fixed to the inner side of the fixing plate 83 through the conductive slot fixing seat 82. The conductive slot fixing seat 82 adopts a clamping fixing structure, and the entire conductive slot 81 is fixed on the fixing plate 83 through a plurality of conductive slot fixing seats 82. The conductive slot 81 is usually made of ceramic or other insulating materials, and has a V-shaped or similar groove, and the conductive bar 80 is fixed in the conductive slot 81. The conductive bar 80 is usually made of copper. The conductive strips 80 in the two conductive slots 81 serve as positive and negative electrodes of a power source, respectively, and are connected to an external power source via a wire 84, thereby forming charging electrodes.

[0057] See Figures 13 to 17As shown, the current collector 7 includes: a substrate 71 and two groups of conductive sliding contact units 70 installed on the substrate 71. The substrate 71 is connected to the mover base 91 through a connecting plate 72, and the connecting plate 72 can be fixed by screws. Of course, in order to achieve quick matching, the connecting plate 72 can be connected by snap-in connection, strong magnetic adsorption, etc. After the mover carrier 9 is transported to the magnetic levitation charging track 2, the connection between the mover carrier 9 and the current collector 7 is realized 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 a wire, waiting for the charging operation.

[0058] The conductive sliding contact unit 70 has a conductive brush 73 connected to the substrate 71 through an elastic movable link mechanism, and the energy storage unit 92 is connected to the conductive brush 73 through a wire. The elastic movable link mechanism can overcome the occurrence of adverse conditions such as jumping and displacement deviation during the operation process, ensuring that the conductive brush 73 is stably connected to the conductive strip 80 in the sliding contact charging device 8.

[0059] Specifically, 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 by a connecting bolt 77, and the connecting bolt 77 is also a component connected to the connecting plate 72, and the connecting plate 72 is fixed to the substrate 71 through the cooperation of the nut and the connecting bolt 77.

[0060] A pair of ear plates are formed on one side of the connection seat 76, and the swing arm 75 is elastically pivoted between the two ear plates of the connection seat 76 to achieve swinging along the pivot position 750. A limit plate 752 is provided at one end of the swing arm 75, and the other end is used to connect with the connection pin 74. The limit plate 752 is used to limit the swing amplitude of the swing arm 75, and a wire positioning ring 753 is provided on the outer side of the limit plate 752. The charging connection line for connecting the energy storage unit 92 and the conductive brush 73 passes through the wire positioning ring 753 to achieve the positioning of the charging connection line.

[0061] A compression spring 751 is provided between the swing arm 75 and the connection seat 76, and a certain elastic force is applied to the swing arm 75 by the compression spring 751, thereby driving the end connected to the connection pin 74 to have a tendency to move toward the sliding contact charging device 8. The compression spring 751 is installed in such a way that accommodating grooves that can cooperate with the two ends of the compression spring 751 are respectively provided on the inner side of the connection seat 76 and in the middle of the swing arm 75, and the two ends of the compression spring 751 are limited by the accommodating grooves.

[0062] One end of the swing arm 75 that is slidably connected to 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 .

[0063] A compression spring 741 is sleeved on the connecting pin 74. A limiting end cap 742 is formed at one end of the connecting pin 74, and a pivoting portion 743 connected to the conductive brush 73 is provided at the other end. The limiting end cap 742 is in a wedge shape that matches the groove 755, and the connecting pin 74 and the pin hole 754 are in a shaft hole sliding fit. Under the elastic force of the compression spring 741, the limiting end cap 742 is pressed tightly in the groove 755. At the same time, since the limiting end cap 742 and the groove 755 are in a wedge-shaped nested fit, the connecting pin 74 can be kept in a quick reset even if it rotates along its axis.

[0064] The conductive brush 73 is usually a carbon brush, and is fixed on a brush holder 731. The brush holder 731 has a pivoting position 730 pivotally connected with the pivoting portion 743, and a wiring slot 732 for connecting a charging connection line. The charging connection line for connecting the energy storage unit 92 and the conductive brush 73 will eventually be connected to the wiring slot 732 to realize the conduction of the entire charging circuit.

[0065] The present invention achieves stable conductive contact through the collector 7, so that the energy storage unit 92 is connected to the conductive brush 73 through the wire, and can overcome adverse conditions such as jumping and displacement deviation during the operation process, ensuring stable conductive contact between the conductive brush 73 and the conductive bar 80 in the sliding contact charging device 8.

[0066] As described above, the charging and discharging method of the magnetic suspension transmission system adopted by the present invention is as follows: the mover carrier generates magnetic force through the stator unit and the action of the mover magnet, runs along the magnetic suspension transmission track, realizes the transmission of the mover carrier, and during the passing process, discharges through the energy storage unit to power the electrical equipment carried on the mover carrier; when charging, first, the mover carrier 9 runs to the position of the left track section 3, and descends to the position flush with the magnetic suspension charging track 2 through the left lifting device 5;

[0067] Secondly, the mover carrier 9 is connected to the current collector 7 to realize synchronous operation of the mover carrier 9 and the current collector 7, and the energy storage unit 92 is connected to the conductive brush 73 of the current collector 7 through a charging wire to realize sliding contact with the conductive strip 80, thereby charging the energy storage unit 92;

[0068] Then, while charging or after charging is completed, the mover carrier 9 is driven by the magnetic suspension charging track 2 to move toward the right track segment 4 until it moves to the right track segment 4 that has already been lowered along with the right lifting device 6;

[0069] Finally, the current collector 7 is separated from the mover carrier 9 to disconnect the circuit between the energy storage unit 92 and the current collector 7. Driven by the right lifting device 6, the mover carrier 9 rises along with the right track segment 4, so that the right track segment 4 is reconnected with the main track segment 10. The mover carrier 9 that has completed charging returns to the magnetic levitation transmission track 1 again to perform corresponding transmission operation.

[0070] See Fig.18 As shown, this is a three-dimensional diagram of the present invention in use.
