[0047] To enable those skilled in the art to better understand the technical solutions in this application, the technical solutions in the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments.

[0048] In the description of the embodiments of this application, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of indicated technical features. Therefore, a feature defined as "first" or "second" may explicitly or implicitly include at least one of that feature. In the description of this application, "multiple" means at least two, such as two, three, etc., unless otherwise explicitly specified.

[0049] In this application, unless otherwise expressly specified and limited, the terms "installation," "connection," "joining," and "fixing," etc., should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a mechanical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components, unless otherwise expressly limited.

Furthermore, "above," "over," and "on top" of the second feature can mean that the first feature is directly above or diagonally above the second feature, or simply that the first feature is at a higher horizontal level than the second feature. "Below," "below," and "under" the second feature can mean that the first feature is directly below or diagonally below the second feature, or simply that the first feature is at a lower horizontal level than the second feature.

[0051] In a logistics warehousing system, shelving is an important component used to store goods.

[0052] In related technologies, shelving consists of multiple uprights and multiple beams, which are arranged vertically and staggered to form multiple storage locations. After the shelving is installed, workers need to inspect and calibrate each storage location sequentially to ensure that the beam surfaces of the same storage location are on the same horizontal plane.

[0053] However, due to the large number of storage locations and the limited space within them, workers' efficiency in inspecting the locations is low. Similarly, the transfer station, as a transit device for goods entering the shelving, also needs to connect with the inbound and outbound equipment, and it also requires testing and calibration after installation.

[0054] To address the aforementioned problems, this application provides an image recognition-based detection device and a transport box and shelf detection system. The solutions provided by this application will be described in detail below with reference to the accompanying drawings.

[0055] Figure 1 This is a schematic diagram of the structure of a detection device for applied image recognition provided in an embodiment of this application; Figure 2 yes Figure 1 A top view of a detection device for image recognition applications.

[0056] Reference Figure 1 and Figure 2 As shown, in a first aspect, embodiments of this application provide a detection device using image recognition, including a base frame 100, a controller, and an image acquisition component 200. The controller is housed within an electrical box 400, which is mounted on the base frame 100.

[0057] The electrical box 400 also contains electrical components such as a power supply and a charging module. The power supply provides power to the controller and the image acquisition component 200, and the charging module is used to charge the power supply. These are all existing technologies and will not be described in detail here.

[0058] The image acquisition component 200 is mounted on the base frame 100 and is electrically connected to the controller. The controller acquires images of the detection markers located at the storage location or transfer platform through the image acquisition component 200 and determines whether there are any abnormalities at the storage location or transfer platform based on the shape of the images. Specifically, when the shape of the image received by the controller is the same as the shape of the image set at the storage location or transfer platform, it indicates that the storage location or transfer platform is normal; otherwise, it indicates that the storage location or transfer platform has tilted or deformed, or other abnormalities. Compared with manual measurement and inspection methods, this device greatly improves inspection efficiency.

[0059] For example, the detection mark can be a QR code or other graphic. It is understood that when the image acquisition component 200 acquires an image of the detection mark located at the storage location, the controller determines whether there is an anomaly at the storage location; when the image acquisition component 200 acquires an image of the detection mark located at the transfer platform, the controller determines whether there is an anomaly at the transfer platform.

[0060] The controller can be configured as a PLC control module. The image acquisition component 200 can be configured as an image acquisition device, barcode scanner, or camera. The image acquisition component 200 can be adapted according to the type of detection mark added to the shelf, which will not be described in detail here.

[0061] When the storage location is functioning normally, the base frame 100 is parallel to the bottom of the storage location, and the image captured by the image acquisition component 200 on the base frame 100 has the same shape as the image set on the storage location. When the storage location is abnormal, the bottom of the storage location may deform or tilt, and the base frame 100 and the bottom of the storage location may no longer remain parallel. In this case, the shape of the image captured by the image acquisition component 200 will be different from the shape of the image on the storage location. Therefore, the controller can determine whether there is an abnormality in the storage location based on whether the shape of the image captured by the image acquisition component 200 is the same as the shape of the image on the storage location.

[0062] In some examples, the image acquisition component 200 is positioned at the center of the base frame 100 to facilitate the acquisition of images located at the storage location.

[0063] Reference Figure 1 and Figure 2 As shown, exemplarily, the base frame 100 may be formed by connecting profiles to simulate a cargo pallet. The base frame 100 provides mounting locations for other components and can be used to connect to a mobile carrier. For example, the base frame 100 can be connected to the forks of a stacker crane.

[0064] In some examples, the detection device further includes a ranging component 500, which is mounted on the base frame 100 and electrically connected to the controller. The ranging component 500 measures the distance between itself and the shelf or transfer station. The controller determines whether there is an anomaly at the shelf location or transfer station based on the measurement results from the ranging component 500 and the image acquisition results from the image acquisition component 200. In some examples, the controller can determine whether there is an anomaly based on either the result from the ranging component 500 or the result from the image acquisition component 200, or it can make a combined judgment based on both results.

[0065] Specifically, the ranging component 500 includes a first ranging unit (not specifically shown in the figure), which measures the distance between itself and the beam of the shelf. For example, there are at least two sets of first ranging units, each connected to the base frame 100, and at least two sets of first ranging units are spaced apart. The first ranging unit measures the distance between itself and the beam of the shelf. The controller is electrically connected to all the first ranging units, and determines the location of the corresponding shelf based on the distance values ​​measured by all the first ranging units. It is understood that multiple first ranging units can detect multiple distance values. The controller calculates the vertical distance between the corresponding ranging component and the beam based on the distance value measured by each ranging component, then compares and calculates the multiple vertical distance values ​​to ultimately determine whether the location is tilted, twisted, or otherwise compromised. Similarly, this ranging component can be used to detect abnormalities at the handover station.

[0066] In some examples, the first ranging unit is mounted on the base frame 100, and its emitted first ranging signal is directed perpendicularly to the crossbeam of the rack location or the crossbeam of the transfer platform. In this case, the measured value of the first ranging unit is the vertical distance between the first ranging unit and the crossbeam. In other examples, the first ranging unit is mounted at an angle on the base frame 100, and its emitted first ranging signal is directed at an angle to the crossbeam. In this case, the controller calculates the vertical distance between the first ranging unit and the crossbeam based on the angle between the first ranging signal and the crossbeam, and the measured value of the first ranging unit. It should be noted that the vertical distance referred to here is the vertical distance between the first ranging unit and the upper crossbeam of the rack location, or the vertical distance between the first ranging unit and the lower crossbeam of the rack location, or the vertical distance between the first ranging unit and the transfer platform.

[0067] In some examples, there are two or four sets of first ranging units. When there are two sets of first ranging units, both sets are installed on the base frame 100 and are located on the same straight line. The two sets of first ranging units measure their own distance from the cargo location or the handover platform to determine the status of the cargo location or the handover platform.

[0068] When there are four first ranging units, the distribution of the four sets of first ranging units can be rectangular, with the four sets of first ranging units respectively set at the four vertices of the rectangular outline.

[0069] In some examples, the first ranging unit includes one or more first ranging modules. When the first ranging unit includes multiple first ranging modules, all the first ranging modules are arranged side by side on the base frame 100, and all the first ranging modules are connected to the controller.

[0070] In some examples, the ranging component further includes a second ranging unit mounted on the base frame 100. This second ranging unit horizontally emits a second measurement signal to measure the distance between itself and the uprights of the storage location. The controller can determine whether any abnormalities, such as deformation, have occurred in the uprights of the storage location based on the distance data detected by the second ranging unit. It should be noted that the second ranging unit operates on the same principle as the first ranging unit described above, which will be understood by those skilled in the art and will not be elaborated upon further here.

[0071] For example, two or four sets of second ranging units are provided. When two sets of second ranging units are provided, the two sets of second ranging units are arranged on the same straight line. When four sets of second ranging units are provided, the four sets of second ranging units are distributed in a rectangle, and the four sets of second ranging units are respectively arranged at the four vertices of the rectangular outline. In addition, each second ranging unit may include multiple second ranging modules, all of which are arranged side by side on the base frame 100, and all of the second ranging modules are electrically connected to the controller.

[0072] For example, the first ranging module and the second ranging module can be laser ranging sensors. The controller controlling the laser ranging sensor to measure the distance is a prior art in this field and will not be described in detail here.

[0073] In some examples, the base frame 100 also includes a first automatic adjustment component and / or a second automatic adjustment component, the first automatic adjustment component being used to adjust the distance between two adjacent first ranging units, and the second automatic adjustment component being used to adjust the distance between two second ranging units.

[0074] In some examples, the base frame 100 includes at least one frame assembly 120, to which the electrical box 400 is connected, and the first ranging unit, the second ranging unit, and the image acquisition component 200 are respectively connected to the frame assembly 120.

[0075] In other examples, the base frame 100 includes a mounting base 110 and at least two frame assemblies 120. The at least two frame assemblies 120 are arranged opposite each other on both sides of the mounting base 110, the electrical box 400 is mounted on the mounting base 110, and the image acquisition assembly 200 is mounted on the mounting base 110. For example... Figure 2 As shown, the horizontal cross-section of the base frame 100 is rectangular, and the two frame groups 120 are respectively set on the two opposite side walls of the base frame 100.

[0076] In some examples, the rack assembly 120 includes a first rack 121, a second rack 122, and a first telescopic assembly 123. The first rack 121 is fixedly connected to the side wall of the fixed base 110, and the first rack 121 is connected to the second rack 122 via the first telescopic assembly 123, with the first rack 121 and the second rack 122 arranged perpendicularly to each other. Specifically, one end of the first rack 121 can be welded perpendicularly to the side wall of the fixed base 110, or it can be fixed thereto by locking bolts. The other end of the first rack 121 is fixed to one end of the first telescopic assembly 123, and the other end of the first telescopic assembly 123 is fixed to the second rack 122. The first telescopic assembly 123 controls the distance between the second rack 122 and the fixed base 110, thereby changing the overall width to simulate pallets of different widths placed in the storage location. In other examples, the fixed base 110 can be directly fixed to the first rack 121.

[0077] For example, a first ranging unit is disposed on a first frame 121, and a first telescopic component 123 is configured as the aforementioned first automatic adjustment component. The first telescopic component 123 extends and retracts, thereby adjusting the position of the first ranging unit and changing the distance between two adjacent first ranging units. A second ranging unit may be disposed at the end of a second frame 122.

[0078] In some examples, a second automatic adjustment component (not shown in the figure) is provided at the end of the second frame 122. Multiple second ranging units are arranged vertically at intervals on the second automatic adjustment component. The second automatic adjustment component can adjust the distance between two adjacent second ranging units, thereby changing the measurement position of the second ranging unit relative to the storage location column and improving the accuracy of the storage location status determination. Exemplarily, the second automatic adjustment component can be a telescopic component, such as an electric cylinder component, which is prior art and will not be described further here.

[0079] Additionally, the second frame 122 can also be configured as a telescopic member, with both ends extendable to change its overall length, simulating the placement of pallets of different lengths in the storage location or handover platform. It should be noted that the pallet width can be referenced... Figure 1 As shown in the y-direction, the length of the tray can be referenced. Figure 1 As shown in the x-direction. It is understood that both the first and second ranging units can be mounted on the second frame 122, for example, both can be mounted at the ends of the second frame. It is also understood that technicians can adjust the specific positions of the first and second ranging units as needed.

[0080] In other examples, the first telescopic assembly 123 includes a connecting frame 1231 and a first drive assembly 1232. One end of the first frame 121 is fixedly connected to the fixed base 110, and the other end is slidably connected to the connecting frame 1231 via a guide rail. The connecting frame 1231 is welded to the second frame 122. The first drive assembly 1232 is mounted on the connecting frame 1231 and drives the first frame 121 to move relative to the connecting frame 1231, thereby changing the distance between the second frame 122 and the fixed base 110. Exemplarily, the first telescopic assembly 123 can be a pneumatic cylinder, a hydraulic cylinder, or an electric cylinder, or it can be a motor-driven rack and pinion assembly or a motor-driven lead screw and nut assembly.

[0081] In this embodiment, the first telescopic component 123 is configured as a motor-driven rack and pinion assembly. This rack and pinion assembly includes a drive motor 311, a drive gear, and a rack (not shown in the figure). The rack is fixedly connected to the first frame 121, the drive motor 311 is fixedly mounted on the connecting frame 1231, and the gear is fixedly mounted on the output end of the drive motor 311, meshing with the rack. When the drive motor 311 rotates, it can drive the connecting frame 1231 to move via the gear and rack, thereby causing the second frame 122 to move relative to the fixed base 110.

[0082] In some examples, the first telescopic assembly 123 further includes a second drive assembly 1233, and the second frame 122 has at least two. At least two second frames 122 are slidably connected to the connecting frame 1231, and are arranged opposite to each other. The second drive assembly 1233 is disposed on the connecting frame 1231, and drives all second frames 122 to extend or retract simultaneously, changing the overall length to simulate the placement of pallets of different lengths in goods.

[0083] For example, the second drive component 1233 can also be a pneumatic cylinder, a hydraulic cylinder, or an electric cylinder, or it can be a motor-driven gear and rack assembly or a motor-driven lead screw and nut assembly. Figure 2 As shown, this embodiment of the application has two second frames 122, and the second drive assembly 1233 is also configured as a motor-driven gear and rack assembly. Each second frame 122 slides on the connecting frame 1231 via a guide rail, and one end of each second frame 122 is fixedly connected to a rack. The drive motor 311 is mounted on the connecting frame 1231, and the drive motor 311 drives the two second frames 122 to extend or retract simultaneously via the gear and rack.

[0084] Figure 3 yes Figure 1 Side view of the cargo location detection device.

[0085] Reference Figure 3 As shown, in some examples, the pallet detection device further includes a fork clamping assembly 300. Exemplarily, the fork clamping assembly 300 includes a clamping drive assembly 310 and at least one set of clamping parts 320. The clamping drive assembly 310 is mounted on the lower surface of the base frame 100, and at least one set of clamping parts 320 are fitted onto the clamping drive assembly 310. The clamping drive assembly 310 drives all clamping parts 320 to clamp onto the forks. Exemplarily, the clamping drive assembly 310 includes a drive motor 311 and a transmission screw 312. The drive motor 311 is fixedly mounted on the lower surface of the base frame 100, and the output end of the drive motor 311 is fixedly connected to the end of the transmission screw 312 via a coupling. The transmission screw 312 has threads in opposite directions spaced apart, and each thread segment is fitted with a clamping part 320. When the drive motor 311 drives the transmission screw 312 to rotate, adjacent clamping parts 320 move relative to each other and are ultimately clamped onto the forks.

[0086] Figure 4 This is a schematic diagram of a transport box for a testing device provided in one embodiment of this application.

[0087] Secondly, referring to Figure 4 As shown in the figure, this application embodiment also provides a transport box for storing the detection device for image recognition application described in the first aspect. The transport box for the detection device includes a box body 600 and a conical sleeve structure 700.

[0088] When the detection device is not in use, its base frame is connected to the interior of the housing 600 via a conical sleeve structure 700. The ranging component 500 of the detection device performs ranging calibration based on the bottom of the housing 600. Specifically, the ranging component 500 may shift in position due to collisions or vibrations, resulting in measurement errors. The bottom surface inside the housing is flat. When the detection device is placed inside the housing 600, because the detection device is positioned, the distance between the ranging component and the bottom or side surface of the housing 600 is fixed. The ranging component 500 uses the bottom or side surface inside the housing 600 as a reference surface for ranging calibration, thereby ensuring the detection accuracy of the detection device.

[0089] For example, the cone-sleeve structure 700 includes a cone and a sleeve. The cone is fixedly disposed on the lower surface of the base of the detection device, and the sleeve is fixedly disposed on the bottom surface inside the housing 600. The cone can be fitted into the sleeve. When the cone is fitted into the sleeve, the detection device is fully positioned.

[0090] Thirdly, embodiments of this application provide a rack inspection system, including a stacker crane and the image recognition-based inspection device described in the first aspect. The stacker crane sequentially places the location inspection device at each location on the rack to detect whether any abnormalities exist in the locations on the rack. Compared to the manual measurement method in the prior art, this rack inspection system greatly improves the efficiency of rack inspection and calibration. Furthermore, since this rack inspection system includes the location inspection device from any of the above-described technical solutions, it possesses all the beneficial effects of the location inspection device from any of the above-described technical solutions, which will not be elaborated further here.

[0091] It is readily understood that, based on the several embodiments provided in this application, those skilled in the art can combine, split, or reorganize the embodiments of this application to obtain other embodiments, none of which exceed the protection scope of this application.

[0092] The above detailed embodiments further illustrate the purpose, technical solution, and beneficial effects of the embodiments of this application.
