An autonomous mobile robot (AMR) walking track and walking shelf

Abstract

This utility model proposes an autonomous mobile robot (AMR) walking track and walking rack, which solves the problems of existing track-type racks requiring separate assembly of frames adapted to their wheels and complex rack assembly when dealing with AMR transportation operations. The main solution includes: a track plate, the center of which has a groove recessed downward along its track to form two symmetrical roller surfaces on both sides of the track plate. The two roller surfaces are set flat, and the groove passes through both ends of the track plate in the track direction. Its bottom surface is flat for attaching external barcodes. The side of the groove that connects to the two roller surfaces is an outwardly inclined slope. Each roller surface is continuously bent on the side opposite to the slope and has a hole at the end of the bend for bolt fixing to the external rack beam.

Description

Technical Field

[0001] This utility model relates to the field of AMR equipment technology, and in particular to an autonomous mobile robot (AMR) walking track. Background Technology

[0002] AMR (Autonomous Mobile Robot) is an industrial robot used to lift and transport materials such as pallets, navigating autonomously by reading QR codes and sensing obstacles. These robots are widely used in warehouses, distribution centers, and production facilities to meet the needs of intelligent warehouse transportation operations.

[0003] Currently, most existing shelving layers in smart warehouses are rail-based structures (such as four-way vehicle rail frames). However, for AMRs, a separate frame corresponding to its wheels is required, and the frame structure must meet its reversing range requirements. This approach is obviously more complex for the overall shelving assembly. Therefore, we propose an autonomous mobile robot (AMR) walking track to solve the above problems. Utility Model Content

[0004] The technical problem to be solved by this utility model is to overcome the defects of the existing technology. This utility model proposes an autonomous mobile robot (AMR) walking track, which replaces the traditional track frame with an M-shaped track plate structure. The frame assembly process is simpler and the AMR walking and reversing is more stable.

[0005] To solve the above-mentioned technical problems, the technical solution adopted by this utility model is: an AMR walking track, including: a track plate, the center of the track plate having a groove recessed downward along its track to form two symmetrical roller surfaces on both sides of the track plate, the two roller surfaces being set flat, the groove being through to both ends of the track plate in the track direction, the bottom surface of which is flat for attaching external barcodes, the side of the groove connecting to the two roller surfaces being an outwardly inclined slope, each roller surface being continuously bent on the side opposite to the slope and having a hole at the end of the bend for bolt fixing to the external shelf beam.

[0006] Furthermore, the groove depth is 40mm-50mm, with the bottom surface of the groove as the plane, and the outward inclination angle of the inclined surface is 100°-120°.

[0007] Furthermore, one end of the roller surface is bent inward at 90° twice to form an M-shaped structure, and the end of the bend is flush with the bottom surface of the groove.

[0008] Furthermore, each concave, outward tilt, and bend on the track plate is chamfered.

[0009] Furthermore, the width of each roller surface is 140mm-160mm.

[0010] Furthermore, the width of the bottom surface of the groove is not less than 50mm.

[0011] Furthermore, the track slab is made of Q235 stainless steel.

[0012] A mobile shelving unit, comprising any of the AMR mobile tracks described above.

[0013] Furthermore, the traveling rack includes AMR traveling tracks of various lengths, and the track plates in each traveling track are molded as a single piece.

[0014] Compared with the prior art, the beneficial effects of this utility model include: the two parallel roller surfaces can meet the driving requirements of the bottom walking wheels and reversing wheels of the AMR. During the walking and reversing process, the two wheels roll and contact the roller surfaces. Similarly, for the scanning and positioning of the bottom of the AMR, codes can be manually affixed to the bottom surface of the groove, and the AMR can be identified and positioned synchronously during the driving process. As for the installation and positioning of the track plate, it is easier to install by making holes at the outer bent end and fixing it to the external shelf beam with bolts at the holes. The installed track plate has a high flatness, which is more conducive to the positioning accuracy requirements during the driving process of the AMR. Attached Figure Description

[0020] It is readily understood that, based on the technical solution of this utility model, those skilled in the art can propose various interchangeable structural methods and implementations without altering the essential spirit of this utility model. Therefore, the following detailed embodiments and accompanying drawings are merely illustrative descriptions of the technical solution of this utility model and should not be considered as the entirety of this utility model or as limitations or restrictions on the technical solution of this utility model.

[0021] According to one embodiment of the present invention, in conjunction with Figures 1-3 As shown.

[0022] Regarding the overall structure, such as Figure 1 As shown, in this embodiment, an autonomous mobile robot (AMR) walking track includes: a track plate 1, the center of which has a groove 2 recessed downward along its track to form two symmetrical roller surfaces 3 on both sides of the track plate 1. The two roller surfaces 3 are set flat, and the groove 2 passes through both ends of the track plate 1 in the track direction. Its bottom surface is flat for attaching external barcodes. The side of the groove 2 that connects to the two roller surfaces 3 is an outwardly inclined slope 4. Each roller surface 3 is continuously bent on the side opposite to the inclined slope 4 and has a hole at the end of the bend for bolting to an external shelf beam.

[0023] Two parallel roller surfaces 3 can meet the travel requirements of the AMR's bottom traveling wheels and reversing wheels. During the travel and reversing process, the two wheels roll in contact with the roller surfaces 3. Similarly, for the scanning and positioning of the AMR's bottom, codes can be manually affixed to the bottom surface of the groove 2, and the AMR can be identified and positioned synchronously during travel. As for the installation and positioning of the track plate 1, it is installed by making holes at the outer bent end and fixing it to the external shelf beam with bolts at the holes. The installation method is simpler, and the installed track plate 1 has a high flatness, which is more conducive to the positioning accuracy requirements during AMR travel.

[0024] Furthermore, the groove 2 has a depth of 40mm-50mm, with the bottom surface of the groove 2 as the plane, and the outward inclination angle of the inclined surface 4 is 100°-120°. The roller surface 3 is bent at one end by two consecutive 90° inward bends to form an M-shaped structure, with the end of the bend flush with the bottom surface of the groove 2. Each concave, outward inclination, and bend on the track plate 1 is chamfered.

[0025] Furthermore, regarding other structural details of the M-shaped track plate 1, the width of each roller surface 3 is 140mm-160mm. The bottom width of the groove 2 is not less than 50mm. The track plate 1 is made of Q235 steel.

[0026] Similarly, a mobile shelving system incorporating the aforementioned AMR (Automatic Ranging) tracks is also within the scope of protection of this utility model. Furthermore, in some embodiments, the mobile shelving system includes AMR tracks of various lengths, with each track's track plate 1 being integrally molded. The integrally molded track plate 1 has higher structural rigidity and stronger load-bearing capacity.

[0027] The technical scope of this utility model is not limited to the content described above. Those skilled in the art can make various modifications and variations to the above embodiments without departing from the technical concept of this utility model, and all such modifications and variations should fall within the protection scope of this utility model.
