Description

Technical field:

[0001] The utility model relates to the technical field of intelligent transmission systems, and in particular to a charging device for a mover carrier used in magnetic levitation transmission, thereby enabling the mover to complete charging operations while in operation. 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 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 set workstations. At this time, the mover module itself needs to have power supply capabilities. 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 operating speed, operating accuracy and operating distance of the mover module, it is unrealistic to directly use wires to supply power. 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 is too troublesome to remove the entire mover module for charging.

[0027] The utility model is a charging device for a moving carrier used in magnetic levitation transmission. Figures 1 to 6 As shown, the utility model includes: a magnetic levitation charging track 2, a current collector 7, a sliding contact charging device 8 and a mover carrier 9.

[0028] The drive between the mover carrier 9 and the magnetic levitation charging track 2 in this utility model is electromagnetic. Specifically, magnetic stator units are evenly distributed along the track of the magnetic levitation charging track 2. Hall elements are positioned adjacent to each set of stator units to determine the direction of motion of the mover carrier 9. Under the influence of an external power source, the stator units generate electromagnetic force, which interacts with the magnets within the mover carrier 9 to propel the mover carrier 9 along the track, 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 can be made to the existing patent literature in the background art, and this utility model will not be elaborated upon.

[0029] The mover carrier 9 comprises 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 located below the base 91. The energy storage unit 92 is typically 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 enable remote control of the electric component 93. In this way, the mover carrier 9 can be used as a mobile workstation, running to a designated location and performing related operations.

[0030] To ensure stable operation of the mover carrier 9 on the magnetic levitation charging track 2, a track-type mating structure is employed between the mover carrier 9 and the magnetic levitation charging track 2. Slide rail sleeves 911 are symmetrically positioned on either side of the base 91 of the mover carrier 9. The magnetic levitation charging track 2 is equipped with two parallel guide rails 201 of identical specifications. The slide rail sleeves 911 nest with the guide rails 201, allowing them to slide along the guide rails 201. Of course, the slide rail sleeves 911 can also utilize guide wheels.

[0031] The sliding contact charging device 8 is arranged parallel to the side of the magnetic levitation charging track 2, and has a conductive bar 80 that provides charging power. When the movable carrier 9 runs on the magnetic levitation charging track 2, the energy storage unit 92 is connected to the conductive bar 80 through the collector 7 by sliding contact to charge the energy storage unit 92.

[0032] The sliding contact charging device 8 comprises a conductive strip 80, a conductive slot 81, a conductive slot fixing seat 82, and a fixing plate 83. The fixing plate 83 is a fixed support component, positioned vertically and parallel to the side of the magnetic levitation charging track 2. Two parallel conductive slots 81 are fixed to the inner side of the fixing plate 83 via the conductive slot fixing seats 82. The conductive slot fixing seats 82 utilize a clamping structure, with multiple conductive slot fixing seats 82 securing the entire conductive slot 81 to the fixing plate 83.

[0033] The conductive slot 81 is typically made of ceramic or other insulating materials and has a V-shaped or similar groove. The conductive strip 80 is fixed in the conductive slot 81. The conductive strip 80 is typically made of copper. The conductive strips 80 in the two conductive slots 81 serve as the positive and negative electrodes of the power supply, respectively, and are connected to an external power supply via wires 84, thereby forming charging electrodes.

[0034] See Figures 7 to 10 As shown, the current collector 7 includes: a substrate 71 and two groups 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, and the connecting plate 72 can be fixed with 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.

[0035] The conductive sliding contact unit 70 includes a conductive brush 73 connected to the base plate 71 via an elastically movable linkage mechanism. The energy storage unit 92 is electrically connected to the conductive brush 73 via a wire. This elastically movable linkage mechanism prevents undesirable conditions such as jitter and displacement during operation, ensuring stable contact between the conductive brush 73 and the conductive strip 80 in the sliding contact charging device 8.

[0036] Specifically, two conductive sliding contact units 70 are arranged horizontally and parallel to the outer side of the base plate 71. Each conductive sliding contact unit 70 includes a conductive brush 73, a connecting pin 74, a swing arm 75, and a connecting base 76. The connecting base 76 is fixed to the outer side of the base plate 71 via a connecting bolt 77. The connecting bolt 77 also serves as a component for connecting to the connecting plate 72. The connecting plate 72 is fixed to the base plate 71 through the engagement of the nut and the connecting bolt 77.

[0037] A pair of lugs are formed on one side of the connecting base 76. The swing arm 75 is elastically pivoted between the two lugs of the connecting base 76, enabling swinging along the pivot point 750. A limit plate 752 is provided at one end of the swing arm 75, and the other end is connected to the connecting pin 74. This limit plate 752 is used to limit the swing range of the swing arm 75. A wire locating ring 753 is also provided on the outer side of the limit plate 752. The charging cable connecting the energy storage unit 92 and the conductive brush 73 passes through the wire locating ring 753 to ensure the charging cable is properly positioned.

[0038] A compression spring 751 is disposed between the swing arm 75 and the connection base 76. This spring 751 applies a certain elastic force to the swing arm 75, thereby causing the end connected to the connection pin 74 to move toward the sliding contact charging device 8. The compression spring 751 is installed by providing a receiving groove on the inner side of the connection base 76 and in the middle of the swing arm 75, respectively, which can accommodate the two ends of the compression spring 751. The receiving grooves restrain the two ends of the compression spring 751.

[0039] A pin hole 754 is formed on one end of the swing arm 75 that is slidably connected to the connecting pin 74 , and the upper end of the pin hole 754 is a wedge-shaped groove 755 .

[0040] A compression spring 741 is sleeved onto the connecting pin 74. One end of the connecting pin 74 is formed with a limiting end cap 742, and the other end is provided with a pivoting portion 743 that connects to the conductive brush 73. The limiting end cap 742 is wedge-shaped and fits into the groove 755. The connecting pin 74 and the pin hole 754 form a sliding axial hole fit. Under the elastic force of the compression spring 741, the limiting end cap 742 is pressed tightly into the groove 755. Furthermore, the wedge-shaped nesting fit between the limiting end cap 742 and the groove 755 ensures that the connecting pin 74 will quickly return to its original position even if it rotates along its axis.

[0041] The conductive brush 73 is typically a carbon brush and is fixed to a brush holder 731. The brush holder 731 has a pivot point 730 that pivots with the pivot portion 743 and a connection slot 732 for connecting the charging cable. The charging cable connecting the energy storage unit 92 and the conductive brush 73 is ultimately connected to the connection slot 732, completing the entire charging circuit.

[0042] The present invention achieves stable conductive contact through the current 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 operation, ensuring stable connection between the conductive brush 73 and the conductive bar 80 in the sliding contact charging device 8.

[0043] When the mover carrier 9 in the present invention is charged, the mover carrier 9 is connected to the current collector 7 to achieve 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 the charging wire to achieve sliding contact with the conductive bar 80, thereby charging the energy storage unit 92.

[0044] 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.
