Technical Field

[0001] The utility model relates to the technical field of material handling, and in particular to a material rack device adapted for a latent AMR. Background Art

[0002] The Autonomous Mobile Robot (AMR) is a type of robot widely used in the logistics and warehousing industries. It can autonomously navigate and perform material handling tasks. A lurking AMR is characterized by its ability to "lurk" beneath material racks or pallets, lifting and moving them to designated locations via its lifting mechanism. This design allows the AMR to move efficiently within a warehouse or production line without the need for specialized traction or pushing equipment, significantly improving logistics efficiency and flexibility while reducing the need for manual handling and associated costs. In smart manufacturing and smart logistics systems, lurking AMRs are a key component in achieving automation and intelligence.

[0003] Currently, customers typically manufacture various types of racks based on their original requirements. However, the selection process for potential AMRs requires consideration of factors such as length, width, height, weight, and center of gravity, with the minimum value for a single variable being chosen. For example, if the length just meets the selection criteria, other parameters may fall far below the AMR's design parameters, resulting in handling waste.

[0004] With respect to the above technical problems, the existing technology has not yet proposed an effective solution. Utility Model Content

[0005] The main purpose of the utility model is to provide a material rack device suitable for a latent AMR, so as to solve the technical problem in the prior art that the material rack size is limited and causes waste in transportation.

[0010] Furthermore, the support part includes a plurality of first support rods, which are vertically arranged and spaced apart along the circumference of the bottom frame structure. The plurality of first support rods are connected to the outer periphery of the bottom frame structure, and the multi-layer material racks are spaced apart along the height direction of the first support rods.

[0011] Furthermore, the partition portion includes a plurality of second support rods, and a plurality of second support rods are connected between two adjacent first support rods, one end of the second support rod is connected to a first support rod, and the other end of the second support rod is connected to another first support rod.

It should be understood that the terms used in this way are interchangeable where appropriate, so that the embodiments of the present application described herein can, for example, be implemented in an order other than those illustrated or described herein.

[0030] Now, exemplary embodiments according to the present application will be described in more detail with reference to the accompanying drawings. However, these exemplary embodiments can be implemented in a variety of different forms and should not be interpreted as being limited to the embodiments described herein. It should be understood that these embodiments are provided to make the disclosure of this application thorough and complete, and to fully convey the concepts of these exemplary embodiments to those of ordinary skill in the art. In the accompanying drawings, for the sake of clarity, the thickness of layers and regions may be exaggerated, and the same reference numerals are used to represent the same devices, and thus their descriptions will be omitted.

[0031] Combine Figures 1 to 2 As shown, according to a specific embodiment of the present utility model, a material rack device adapted for a latent AMR is provided.

[0032] Specifically, if Figure 1 、 Figure 2 As shown, a material rack device suitable for a latent AMR includes: a support portion 10, the bottom of the support portion 10 has a receiving space for receiving an AMR tray 100; a partition portion 20, the partition portion 20 is spaced apart along the height direction of the support portion 10 to separate the support portion 10 into multiple layers of material racks 30; wherein the length of at least one side of the support portion 10 is a, 1305.5mm≤a≤1306.5mm.

[0033] In this embodiment, the support part 10 is divided into multiple layers of racks 30 by setting the partition part 20 along the height direction of the support part 10, which can increase the cargo carrying capacity of the rack device, so as to make full use of the vertical handling capacity of the AMR and achieve higher space utilization. By setting the precise size design of the side length a, the rack device can be adapted to the size of the AMR pallet, ensuring that the rack device can be stably placed on the AMR, reducing displacement or shaking during transportation, and improving the working efficiency of the overall system.

[0034] Furthermore, at least one side of the support portion 10 has a width b, where 1205.5 mm ≤ a ≤ 1206.5 mm. Precise control of width b helps reduce lateral sway during handling, especially when the AMR makes an emergency stop, accelerates, or turns. This improves handling safety and reduces the risk of tipping.

[0035] Furthermore, the height of the support portion 10 is defined as c, where 1263.5 mm ≤ a ≤ 1264.5 mm. This precise setting of height c ensures that the rack matches the physical limits of the potential AMR's top, preventing racks from being placed on the AMR or causing instability during handling due to excessive height. Strict control of height c also considers the AMR's maximum load height, preventing it from exceeding its design parameters and ensuring safe handling.

[0036] Figure 2 This is a planar structural diagram of the base frame structure 11 relative to the AMR pallet. The support portion 10 includes the base frame structure 11, which includes multiple load-bearing bars. The distance d between the base frame structure 11 and the AMR pallet 100 is, where 24.5mm≤d≤25.5mm. The precise setting of distance d takes into account the positioning accuracy and motion errors of the AMR during handling, ensuring that the rack base frame structure 11 can be stably placed on the AMR pallet and maintain a good connection even during the AMR's movement, avoiding displacement or shaking caused by excessive gaps. This spacing is compatible with the motion errors of the AMR during positioning, thereby maximizing the tilt lever arm and increasing the tipping angle during acceleration and deceleration.

[0037] In some optional embodiments, a QR code is pasted on the central connecting plate of the bottom frame structure 11, which can be used by the AMR to read the QR code during the positioning process to improve the positioning accuracy.

[0038] Furthermore, the support portion 10 includes a plurality of first support rods 12, which are vertically arranged and spaced apart along the circumference of the bottom frame structure 11. The plurality of first support rods 12 are connected to the outer periphery of the bottom frame structure 11, and the multi-layer material racks 30 are spaced apart along the height direction of the first support rods 12 to improve the overall stability and reliability.

[0039] In this embodiment, four first support rods 12 are provided. In other embodiments, the number of the first support rods 12 is not limited thereto, and may also be five, six, or the like.

[0040] Furthermore, the partition portion 20 includes a plurality of second support rods 21, and a plurality of second support rods 21 are connected between two adjacent first support rods 12, one end of the second support rod 21 is connected to a first support rod 12, and the other end of the second support rod 21 is connected to another first support rod 12. The plurality of second support rods 21 are arranged horizontally at intervals to separate the support portion 10 into multiple layers of material racks 30, and each layer of material racks 30 is connected to each layer of second support rods 21. This arrangement improves the carrying capacity of the material rack device.

[0041] Furthermore, each layer of the material racks 30 is constructed from aluminum alloy, and each rack 30 is equipped with a flow bar 31. Aluminum alloy has a good strength-to-weight ratio, significantly reducing the weight of the racks compared to other metals such as steel. Due to the limited load capacity of the AMR, the lightweight design of the racks increases its payload and allows for the handling of more cargo. The flow bar 31 is an inclined guide rail, along which cargo slides under the influence of gravity. This reduces manual labor during the unloading phase and improves the efficiency of loading and unloading cargo. The use of the flow bar is particularly suitable for frequent loading and unloading of bins or parts.

[0042] Furthermore, the material of the support portion 10 is set to be aluminum alloy, so that the structure of the material rack device is light and the handling efficiency is improved.

[0043] Furthermore, two directional wheels 50 are connected to the bottom of the first support rod 12 to facilitate the fixation of the device and prevent slippage.

[0044] Furthermore, two universal wheels 40 are connected to the bottom of the first support rod 12 to improve the flexibility of the entire device.

[0045] From the above description, it can be seen that the above embodiments of the present invention achieve the following technical effects:

[0046] (1) Design multi-layer racks, using specific dimensions (such as 1306*1206*1264mm) and a load capacity of 400KG to optimize the handling efficiency of potential AMRs.

[0047] (2) Use 2 fixed wheels and 2 universal wheels to improve flexibility when not in transport mode.

[0048] (3) Using 32mm diameter aluminum profiles as the main frame reduces the overall weight of the rack and helps improve handling efficiency.

[0049] (4) The three-layer material rack uses aluminum alloy and smooth strip structure to reduce the burden of manual material placement and improve work efficiency.

[0050] (5) Consider the running speed and acceleration parameters of the latent AMR (1.5m / s and 1m / s 2 ) to ensure stability in an emergency stop and avoid overturning.

[0051] (6) The base plate adopts a frame structure, and the distance between the load-bearing bar and the lifting plate is 25mm, which not only ensures compatibility but also improves the tilting force arm to maintain a higher overturning angle during acceleration and deceleration.

[0052] (7) The central connecting plate of the bottom frame structure 11 is designed to be used for pasting QR codes, thereby improving the AMR positioning accuracy and further improving the handling efficiency.

[0053] For ease of description, spatially relative terms such as "above", "above", "on the upper surface of", "above", etc. may be used herein to describe the spatial positional relationship of a device or feature to other devices or features as shown in the figures. It should be understood that spatially relative terms are intended to include different orientations of the device in use or operation in addition to the orientation described in the figures. For example, if the device in the drawings is inverted, the device described as "above other devices or structures" or "above other devices or structures" will be positioned as "below other devices or structures" or "below other devices or structures". Thus, the exemplary term "above" can include both "above" and "below". The device can also be positioned in other different ways (rotated 90 degrees or in other orientations), and the spatially relative descriptions used here are interpreted accordingly.
