DETAILED DESCRIPTION

[0033] The following describes in detail embodiments of the present invention, examples of which are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements having the same or similar functions. The embodiments described in the embodiments are intended to explain the present invention and are not to be construed as limiting the present invention.

[0034] References in this specification to "one embodiment," "an example," or "an example" mean that a particular feature, structure, or characteristic described in connection with the embodiment itself can be included in at least one embodiment disclosed herein. The appearance of the phrase "in one embodiment" in various places in the specification does not necessarily refer to the same embodiment.

[0035] A shelf robot usually includes an actuator, a power supply and lifting assembly arranged vertically, and a guide rail structure arranged horizontally. The actuator is used to pick up and place goods or boxes, the power supply and lifting assembly can drive the actuator to move up and down, and the power supply and lifting assembly can slide along the horizontal guide rail, thereby transporting the actuator to each storage location on each layer of the shelf. The actuator can take out the goods or boxes in the storage location and deliver the goods or boxes when it is in the shipping position (for example, when it is handed over to a transport cart or temporary shelf on the ground).

[0036] In existing racking robots, busbars are typically installed on transverse guide rails to provide power to the power supply and actuator components during operation. These rails maintain an electrical connection between the electrodes on the power supply and actuator components, ensuring uninterrupted power supply. However, busbars carry significant material and maintenance costs, particularly when used on large racks with high shelf heights.

[0037] In order to solve the above technical problems, as one aspect of the present invention, a power supply lifting component for a shelf robot is provided, such as Figure 1 、 Figure 4 、 Figure 5 As shown, the power supply lifting assembly includes a vertical rod 100, a lifting seat 200 and a driving module 300. The driving module 300 includes a motor 310 and a lifting mechanism 320. The lifting seat 200 is movably arranged on the vertical rod 100 and connected to the lifting mechanism 320. The motor 310 is used to drive the lifting mechanism 320 to drive the lifting seat 200 to move along the vertical rod 100. The power supply lifting assembly also includes a battery holder 400. The battery holder 400 is detachably provided with a battery 1, and the battery holder 400 electrically connects the electrodes of the battery 1 to the power input end of the motor 310.

The execution component is arranged on the lifting seat 200, and the walking component 700 drives the entire power supply lifting component to move in the horizontal direction, and the driving module 300 drives the lifting seat 200 to drive the execution component to move up and down, so as to realize the transfer of the execution component to different storage locations at different heights for the operation of picking up and placing goods and material boxes. The execution component and the walking component 700 can also be powered by the battery 1 in the battery holder 400.

[0039] The power supply lifting assembly provided by the present invention includes a battery holder 400, in which a detachable battery 1 is provided. The battery 1 can be electrically connected to the motor 310 through the battery holder 400, so that the battery 1 provided on the power supply lifting assembly and capable of moving with the power supply lifting assembly is used to supply power to power modules such as the motor 310, thereby eliminating the need to arrange expensive conductive structures such as busbars on the transverse guide rail 710, thereby reducing the material cost of manufacturing the shelf robot.

[0040] Moreover, when the battery 1 has power supply efficiency problems due to its lifespan or is damaged, the battery 1 can be directly removed from the battery holder 400 for replacement. Compared with the solution in the prior art that requires the entire busbar to be inspected, the maintenance cost of the shelf robot can be effectively reduced and the maintenance efficiency of the shelf robot can be improved.

[0043] As an optional embodiment of the present invention, Figure 2 As shown, the power supply compartment 410 includes a plurality of battery boxes 411, and the plurality of battery boxes 411 are distributed along the length direction of the vertical rod 100, and the power supply contacts are arranged in the battery boxes 411, that is, the power supply compartment 410 can accommodate a plurality of batteries 1 at the same time, so as to connect different numbers of batteries in series to achieve the change of the power supply voltage, thereby improving the adaptability of the shelf robot to the power requirements of different power modules.

[0044] As an optional embodiment of the present invention, Figure 2 As shown, the battery holder 400 further includes a battery bracket 430 .

The charging contacts 520 can contact the contacts of the charging seat 20 fixed on a fixed structure such as a shelf 10, and supply power to the battery seat 400 through the charging connector 530 and the charging line. Therefore, the power supply lifting component can be docked at the position of the charging seat 20 for charging during non-working hours, thereby maintaining the battery power, thereby ensuring the stability of power supply to the relevant power modules on the power supply lifting component.

[0048] As an optional embodiment of the present invention, Figure 3 As shown, the charging bracket 510 includes a vertical plate 511, a side plate 512 and a flat plate 513.

The charging connector 530 is located on the other side of the flat plate 513 and the end of the charging connector 530 passes through the wire through hole and is electrically connected to the charging contact 520.

[0049] As an optional embodiment of the present invention, Figure 1 、 Figure 2 As shown, the power supply lifting assembly also includes a support base 600 and at least one support wheel 610. The support base 600 is fixedly connected to the end of the vertical pole 100. The motor 310 and the battery holder 400 are both fixedly set on the support base 600. The support wheel 610 is set on the side of the support base 600 away from the vertical pole 100.

[0050] In an embodiment of the present utility model, a support base 600 is provided at the bottom of the power supply lifting component. The support base 600 is in rolling contact with the ground through the support wheels 610, so that the power supply lifting component can be supported by the ground, reducing the gravity load applied by the power supply lifting component to the shelf, and ensuring the overall stability of the storage system.

[0051] As an optional embodiment of the present invention, Figure 1 、 Figure 2 As shown, the battery holder 430 is fixedly mounted on the support base 600 .

[0052] As an optional embodiment of the present invention, the driving module 300 can be a pulley transmission structure. Specifically, the motor 310 is a rotating motor, and the lifting mechanism 320 includes a driving wheel, a driven wheel and a transmission belt. The driving wheel and the driven wheel are arranged at intervals along the length direction of the vertical rod 100. The transmission belt is wound around the driving wheel and the driven wheel. The lifting seat 200 is fixedly connected to the transmission belt. The motor 310 can drive the driving wheel to rotate so that the transmission belt drives the lifting seat 200 to move along the vertical rod 100.

[0053] Alternatively, the driving module 300 may also be a screw transmission structure, and the motor 310 is also a rotary motor 310 , which can drive the vertically arranged screw to rotate, thereby driving the lifting seat 200 threadably connected to the screw to feed along the vertical rod 100 .

[0058] Moreover, when the battery 1 has power supply efficiency problems due to its lifespan or is damaged, the battery 1 can be directly removed from the battery holder 400 for replacement.
