Description

Technical Field

[0001] This application relates to the field of visual recognition technology, and in particular to a visual recognition element and a material handling system. Background Technology

[0002] When loading and unloading materials on automated CNC machining equipment or EDM equipment, vision recognition blocks are often used as a positioning reference for automated guided forklifts (AGTs) to facilitate the ADT's positioning relative to the CNC machining equipment or EDM equipment for loading and unloading. Vision recognition blocks are generally cuboid in structure. The processing environment of the equipment is prone to oil mist. As the oil mist gradually accumulates on the surface of the vision recognition block, it not only causes glare but also obscures the markings. As a result, the reflective camera cannot recognize the markings on the vision recognition block, leading to inaccurate positioning and affecting material processing efficiency. Utility Model Content

[0003] To address the aforementioned problems, this utility model provides a visual recognition element and a material handling system.

[0004] This utility model provides a visual recognition element for use as a positioning reference for a feeding device and engineering equipment, including:

[0005] The substrate has two mutually obliquely intersecting bottom surfaces, a first top surface, and a second top surface;

[0006] A recognition part for visual recognition of a camera used in a feeding device, the recognition part protruding from at least one of the first top surface and the second top surface, and the top of the recognition part forming a recognition surface parallel to the horizontal plane for visual recognition of a camera used in a feeding device.

[0007] In one embodiment, the identification portion includes a first identification segment and a second identification segment that are perpendicular to each other. The second identification segment is connected to the end of the first identification segment. The first identification segment and the second identification segment protrude from at least one of the first top surface and the second top surface. The top surfaces of the first identification segment and the second identification segment together form the identification surface.

[0008] In one embodiment, the second identification segment protrudes from the first top surface, and the first identification segment protrudes from the intersection of the first top surface and the second top surface.

[0009] In one embodiment, the first identification segment and the second identification segment protrude from the first top surface.

[0010] In one embodiment, the first identification segment and the second identification segment protrude from the first top surface and the second top surface.

[0011] In one embodiment, the angle α formed by the first top surface and the bottom surface is in the range of 10°≤α≤60°, and the angle β formed by the second top surface and the bottom surface is in the range of 15°≤β≤70°.

[0012] In one embodiment, the included angle α is smaller than the included angle β.

[0013] In one embodiment, the identification portion includes two third identification segments that intersect in an X-shape. The two third identification segments protrude from at least one of the first top surface and the second top surface, and the top surfaces of the two third identification segments together form the identification surface.

[0014] In one embodiment, the identification part is a ring structure.

[0015] In one embodiment, the substrate has an assembly hole that passes through the first top surface and the bottom surface.

[0016] Another embodiment of this application provides a material handling system, including a loading device, an engineering device, and a visual recognition element provided in the foregoing embodiments. The loading device is equipped with a camera, and the loading device uses the camera to perform visual recognition on the visual recognition element to locate the relative positions of the loading device and the engineering device.

[0017] The beneficial effects of this utility model are as follows: the first and second top surfaces can not only prevent oil accumulation, but also the oblique intersection of the first and second top surfaces with the bottom surface can reduce light reflection onto the camera lens, thereby improving the accuracy and precision of recognition. The distance difference between the recognition surface and the first and second top surfaces can further avoid recognition errors and further improve the accuracy of recognition.

[0033] Please refer to Figure 1-9 This illustration shows a visual recognition element provided in an embodiment of the present invention, used as a positioning reference for a feeding device and engineering equipment, comprising:

[0034] The substrate 1 has a bottom surface 10, a first top surface 11, and a second top surface 12 that are obliquely intersecting each other;

[0035] The recognition part 2 is used for visual recognition by a camera of a loading device. The recognition part 2 protrudes from at least one of the first top surface 11 and the second top surface 12, and the top of the recognition part 2 forms a recognition surface 20 for visual recognition by a camera of a loading device that is parallel to the horizontal plane.

[0036] In this embodiment, the bottom surface 10 is parallel to the horizontal plane, and the bottom surface 10 is oblique to the first top surface 11 and the second top surface 12. When oil mist is deposited in the working environment, the oil will slide off the first top surface 11 and the second top surface 12 under the action of gravity, reducing the light reflection into the lens and affecting the accuracy of recognition. In addition, the light shining on the first top surface 11 and the second top surface 12 will be reflected in other directions, avoiding the situation where the brightness of the area is too high, causing the camera to be unable to recognize the recognition surface. The identification unit 2 protrudes from at least one of the first top surface 11 and the second top surface 12. On the one hand, the identification surface 20 forms a distance difference with the first top surface 11 and the second top surface 12. Due to the depth of field, the first top surface 11 and the second top surface 12 that do not need to be identified are blurred, which can avoid identification errors. On the other hand, due to light reflection, the identification surface 20 is a bright area, while the first top surface 11 and the second top surface 12 are dark areas. The camera can better identify the identification surface 20, further improving the accuracy and precision of identification. This facilitates more accurate positioning of the loading equipment relative to the engineering equipment, increases the speed of loading and unloading, and improves the efficiency of material processing and transportation.

[0037] In one embodiment, the identification part 2 includes a first identification segment 21 and a second identification segment 22 that are perpendicular to each other. The second identification segment 22 is connected to the end of the first identification segment 21. The first identification segment 21 and the second identification segment 22 protrude from at least one of the first top surface 11 and the second top surface 12. The top surfaces of the first identification segment 21 and the second identification segment 22 together form the identification surface 20.

[0038] In one embodiment, the first identification segment 21 and the second identification segment 22, which are perpendicular to each other, form a T-shape or an L-shape.

[0039] like Figure 1-7As shown, in this embodiment, the first recognition segment 21 and the second recognition segment 22, which are perpendicular to each other, form an L-shape. The top surfaces of the first recognition segment 21 and the second recognition segment 22 together form the recognition surface 20, which can increase the recognition area and further improve the recognition effect and accuracy.

[0040] In one embodiment, the second identification segment 22 protrudes from the first top surface 11, and the first identification segment 21 protrudes from the intersection of the first top surface 11 and the second top surface 12.

[0041] like Figure 1-3 As shown, in this embodiment, the distance difference between the recognition surface 20 and the first top surface 11 and the second top surface 12 can be increased, so that the recognition surface 20 is a bright area and the first top surface 11 and the second top surface 12 are dark areas, and the camera can better recognize the recognition surface 20, further improving the accuracy and precision of recognition.

[0042] like Figure 6-7 As shown, in one embodiment, the first identification segment 21 and the second identification segment 22 protrude from the first top surface 11.

[0043] In one embodiment, the first identification segment 21 and the second identification segment 22 protrude from the first top surface 11 and the second top surface 12.

[0044] like Figure 4-5 As shown, in this embodiment, the distance difference between the recognition surface 20 and the first top surface 11 and the second top surface 12 can be increased, thereby improving the accuracy and precision of the recognition.

[0045] In one embodiment, the included angle α formed by the first top surface 11 and the bottom surface 10 is in the range of 10°≤α≤60°, and the included angle β formed by the second top surface 12 and the bottom surface 10 is in the range of 15°≤β≤70°.

[0046] like Figure 3 , Figure 5 and Figure 7 As shown, the first top surface 11 forms an angle α with the bottom surface 10, and the second top surface 12 forms an angle β with the bottom surface 10. By controlling the angles α and β, the deposition of oil mist can be reduced, thus affecting the accuracy of identification.

[0047] In one embodiment, the angle α formed by the first top surface 11 and the bottom surface 10 is in the range of 10°≤α≤30°, and the angle β formed by the second top surface 12 and the bottom surface 10 is in the range of 15°≤β≤40°. The angles α and β within this range can reduce the deposition of oil mist, save processing materials for visual recognition elements, and make processing more convenient.

[0048] In one embodiment, the included angle α is smaller than the included angle β.

[0049] In this embodiment, the included angle α is smaller than the included angle β, so that the first top surface 11 and the second top surface 12 are dark areas of different brightness, making the recognition surface 20 easier to recognize and improving the accuracy and precision of recognition.

[0050] like Figure 8 As shown, in one embodiment, the identification unit 2 includes two third identification segments 23 that intersect in an X shape. The two third identification segments 23 protrude from at least one of the first top surface 11 and the second top surface 12. The top surfaces of the two third identification segments 23 together form an identification surface 20, which can increase the identification area and further improve the identification effect and accuracy.

[0051] like Figure 9 As shown, in one embodiment, the recognition unit 2 has a ring structure, which can increase the recognition area and further improve the recognition effect and accuracy.

[0052] In one embodiment, the substrate 1 has an assembly hole 3 that passes through the first top surface 11 and the bottom surface 10.

[0053] like Figure 1-2 , Figure 4 , Figure 6 and Figure 8-9 As shown, the visual recognition element can be mounted on the engineering equipment or on the ground near the engineering equipment through the mounting hole 3.

[0054] Another embodiment of this application also provides a material handling system, including a feeding device, an engineering device, and a visual recognition element provided in the foregoing embodiments. The feeding device is equipped with a camera, and the feeding device uses the camera to perform visual recognition on the visual recognition element to locate the relative positions of the feeding device and the engineering device.

[0055] In one embodiment, a visual recognition element is disposed on the engineering equipment, and the feeding equipment uses a camera to visually recognize the visual recognition element to locate the relative position of the feeding equipment and the engineering equipment.

[0056] In this embodiment, the visual recognition element is fixedly mounted on the ground near the engineering equipment. The loading equipment uses a camera to visually recognize the visual recognition element to locate the relative position of the loading equipment and the engineering equipment. This facilitates more accurate positioning of the loading equipment relative to the engineering equipment, increases the loading and unloading speed, and improves the efficiency of material processing and transportation.
