Description

Technical Field

[0001] The utility model relates to the technical field of material rack transportation, in particular to a power supply device for a mobile material rack. Background Art

[0002] As factories have more and more demands for automated equipment, the racks in many factories are no longer moved manually, but are moved and transported by AGV (Automatic Guided Vehicle) or other conveyor lines. For AGV, AGV generally transfers racks by lifting and clamping.

[0003] However, in the process of transporting mobile racks, the size of the racks is often larger than the AGV, and it is difficult to effectively protect the racks through the AGV itself. Therefore, corresponding protective equipment (such as anti-collision strips / sensors, etc.) is usually installed on the racks. There are also some racks with special functions, such as installing conveyor lines on the racks to transport materials, or installing alarm lights on the racks, etc. In these scenarios, the racks need to be powered. Therefore, existing racks are usually equipped with batteries, which power the electrical equipment on the racks. The number of batteries corresponds to the number of racks. When charging or replacing batteries for a large number of racks, the operation is more cumbersome. Utility Model Content

[0044] See also Figure 1 The utility model provides a power supply device for a mobile material rack, which includes a material rack end body 1 and an equipment end body 2 that are snap-connected; a power supply block 25 is elastically provided at the top of the equipment end body 2, and a snap-in groove is provided at the bottom end of the material rack end body 1; the power supply block 25 is slidably connected to the snap-in groove; and the top of the power supply block 25 abuts against the end face of the snap-in groove to make an electrical connection.

[0045] like Figures 5 to 7 As shown, in one embodiment, the rack end body 1 is installed on the rack; the equipment end body 2 is installed on the AGV, and the AGV supplies power to the equipment end body 2. When the rack needs to be transported, the AGV moves to the bottom of the rack and lifts the rack. During this process, the power supply block 25 slides directionally in the snap-in groove until the top of the power supply block 25 abuts against the end surface of the snap-in groove to complete the electrical connection. Of course, after the rack end body 1 and the equipment end body 2 are electrically connected, the AGV can continue to lift the rack. The rack end body 1 and the equipment end body 2 have simple and compact structures and can be installed on the rack and AGV respectively, which is highly practical.

[0046] The power supply block 25 is elastically connected to the device end body 2. When the rack end body 1 and the device end body 2 are snapped together, it can effectively ensure that the top of the power supply block 25 is fully in contact with the end face of the snap-in slot, thereby enhancing the stability of the electrical connection between the rack end body 1 and the device end body 2, and realizing power supply to the rack during movement. The power supply block 25 can be used to electrically connect to the snap-in slot, and can also be snapped into the snap-in slot to limit the rack end body 1, thereby enhancing the connection stability between the rack end body 1 and the device end body 2.

[0047] The equipment end body 2 is electrically connected to the AGV, and the AGV provides the power required by the equipment end body 2 and the rack end body 1, and directly charges the AGV. One AGV can be responsible for the transportation of multiple racks, so there is no need to install batteries on each rack, which optimizes the power supply method for the racks, reduces the problem of a large number of rechargeable batteries required under the condition of transporting a large number of racks, simplifies the number of rechargeable batteries required, and makes the operation simpler.

[0048] See also Figure 2 The device end body 2 includes a device end mounting plate 24, a power supply block 25, a spring 26 and a back plate 27; one end of the spring 26 is connected to the power supply block 25, and the other end is connected to the back plate 27; a through slot 241 is provided in the device end mounting plate 24; and the side of the power supply block 25 is slidably connected to the through slot 241. Specifically, the back plate 27 is connected to the top of the AGV by bolts; the mounting plate 24 is an insulating plate, such as bakelite; and the power supply block 25 is a conductive member, such as copper. The lead wires of the power supply block 25 are electrically connected to the AGV, and the power supply block 25 is powered by the material rack after abutting against the end face of the clamping slot, so that the AGV can power the material rack during movement, and realize power supply to equipment such as anti-collision strips, sensors, conveyor lines or alarm lights on the material rack. The setting of the spring 26 enables the top of the power supply block 25 to fully abut against the end face of the snap-in groove after the rack end body 1 and the device end body 2 are docked, thereby improving the stability of the electrical connection between the two, ensuring continuous power supply to the rack, and maintaining the normal operation of multiple functional devices on the rack. The through groove 241 guides the sliding of the power supply block 25 to ensure that the power supply block 25 is only lifted and lowered in the vertical direction, thereby improving the docking accuracy between the power supply block 25 and the snap-in groove. Optionally, the rack end body 1 and the device end body 2 can be docked and fixed by a snap-on structure, or by a pneumatic clamping mechanism, as long as the connection strength and detachable connection between the rack end body 1 and the device end body 2 can be guaranteed.

[0049] Furthermore, a limiting groove 242 is provided in the through groove 241; the bottom end of the limiting groove 242 is connected to the bottom end of the through groove 241; a limiting block 251 is provided on the side of the power supply block 25; and the limiting block 251 is slidably connected to the limiting groove 242. Specifically, the limiting groove 242 is an open groove, and the opening direction is toward the back plate 27, so that when the clamping groove presses down the power supply block 25, the power supply block 25 has enough space to fall, which can effectively avoid the situation of crushing the power supply block 25 and improve the service life of the power supply block 25. In addition, the top of the limiting groove 242 is not connected to the top of the through groove 241, so that the maximum rising stroke of the limiting block 251 can be limited. When the rack end body 1 and the equipment end body 2 are separated, that is, the equipment end body 2 is not working, the power supply block 25 is reset by the elastic force of the spring 26 and automatically rises to the top position of the limit groove 242. The limit groove 242 limits the rise of the power supply block 25 to prevent the power supply block 25 from falling out of the through groove 241 due to the elastic force, thereby effectively ensuring the stability of the docking between the power supply block 25 and the card slot.

[0050] like Figure 3 As shown, a clamping boss 243 is provided at the bottom end of the mounting plate 24, and a wiring groove is provided in the clamping boss 243. The clamping boss 243 is clamped with the groove provided on the AGV to realize the rapid positioning and installation of the two, thereby improving the installation flexibility of the two. In one embodiment, the wiring groove is slidably connected to the lead wire of the power supply block 25. When the power supply block 25 is raised or lowered, the lead wire slides in the wiring groove, and the wiring groove plays a role in positioning and guiding the lead wire.

[0051] Secondly, a strong magnetic block 23 is provided at the top of the equipment-end mounting plate 24. The strong magnetic block 23 effectively enhances the stability of the connection between the rack-end main body 1 and the equipment-end main body 2, so that the power supply device will not be disconnected between the two main bodies and cause power loss when passing through some bumpy or bumpy sections. Compared with the snap-on structure, the magnetic connection method is more durable and simple. Optionally, the strong magnetic block 23 is an electromagnet, which is electrically connected to the AGV. The characteristics of the electromagnet generating magnetism when it is electrified and losing magnetism when it is powered off further enhance the flexibility of the detachable connection between the rack-end main body 1 and the equipment-end main body 2.

[0052] In addition, the equipment end body 2 also includes a rack detection sensor. The rack detection sensor can be an existing sensor such as a pressure sensor, a laser sensor, an ultrasonic sensor or a grating, as long as the rack detection sensor can detect the rack after the rack end body 1 and the equipment end body 2 are docked. The rack detection sensor transmits the detection signal to the control center of the AGV, and the AGV then supplies power to the equipment end body 2, so that the equipment end body 2 only consumes power when working, and does not consume power when idle, effectively extending the working time of the AGV.

[0053] like Figure 4As shown, the rack end body 1 includes a rack end mounting plate 11 and a conductive block 13; a snap-in groove is provided at the bottom end of the rack end mounting plate 11; a conductive block 13 is provided on the end face of the snap-in groove; and the top of the power supply block 25 can abut against the conductive block 13 to make an electrical connection. The conductive block 13 is electrically connected to the functional equipment of the rack, and the rack is powered by the conductive block 13. The conductive block 13 is provided on the end face of the snap-in groove, which can effectively avoid the situation where the conductive block 13 is damaged by collision and better protect the conductive block 13. The limiting and guiding function of the snap-in groove improves the docking accuracy of the conductive block 13 and the power supply block 25, and the connection stability between the two is ensured by the action of the spring 26.

[0054] Furthermore, the rack end body 1 further includes a reflective plate 12; a reflective sensor 21 is provided on the equipment end body 2; and the reflective plate 12 and the reflective sensor 21 are arranged opposite to each other. In this embodiment, the rack end body 1 further includes a connecting plate 22, and the reflective sensor 21 is installed on the equipment end mounting plate 24 through the connecting plate 22. Compared with the pressure sensor, the effective cooperation between the reflective plate 12 and the reflective sensor 21 can avoid the situation where the conductive block 13 is accidentally touched and energized with the AGV, thereby improving the sensitivity of the equipment end body 2 and extending the working time of the AGV.

[0055] Secondly, the conductive block 13 includes a positive conductive block and a negative conductive block; the positive conductive block and the negative conductive block are arranged in a pair of clamping grooves in a one-to-one correspondence; the power supply block 25 includes a positive power supply block and a negative power supply block; the positive power supply block and the negative power supply block are arranged in a one-to-one correspondence on both sides of the top of the device end body 2; the positive conductive block is electrically connected after abutting against the positive power supply block, and the negative conductive block is electrically connected after abutting against the negative power supply block. While meeting the power supply requirements, the setting of a pair of power supply blocks 25 further enhances the docking accuracy and connection strength with the rack end body 1. Moreover, even if one power supply block 25 is accidentally touched, since the other power supply block 25 is still open-circuited, no circuit loss will occur, and the occurrence of accidental touch power consumption can be effectively avoided. The power supply device is in a power-off state when idle, which also ensures the safety of the power supply device in an idle state.

[0056] It should be understood that the above description of the specific embodiments of the utility model is only for illustrating the technical route and features of the utility model, and its purpose is to enable those skilled in the art to understand the content of the utility model and implement it accordingly, but the utility model is not limited to the above specific implementation methods.
