[0021] In order to explain the technical content, structural features, purposes and effects of the technical scheme in detail, the following will be described in detail in combination with specific embodiments and the accompanying drawings.

[0022] Please refer to Figures 1 to 3 In this embodiment, a shelf for laser feature recognition includes a shelf body 1, a feature plate 2, and an identification feature stick assembly 3. The shelf body 1 has a warehouse body inside, which is used for the robot body (not shown in the figure) to enter and dock with the shelf body 1, so that the robot body moves together with the shelf body 1, and then the goods on the shelf body 1 are transported. The bottom of the shelf body 1 is provided with walking wheels 14 to facilitate the movement of the shelf body 1.

[0023] In this embodiment, the shelf body 1 includes a back plate 11, a top plate 12, and a wheel bracket 13. The back plate 11 is vertically fixed with the top plate 12. The wheel bracket 13 is fixedly installed on the inner side of the back plate 11. The wheel bracket 13 is located at the middle position of the bottom of the back plate 11 and extends forward, so that the wheel bracket 13 and the back plate 11 are fixedly perpendicular to each other.

[0025] In this embodiment, specifically, the first feature plate 21 is fixedly installed on the right side of the top plate 12 and vertically downward, and the second feature plate 22 is fixedly installed on the left side of the top plate 12 and vertically downward. The first feature plate 21 and the second feature plate 22 are symmetrically distributed on the left and right sides.

[0026] The warehouse body is enclosed by the top plate 12 and the back plate 11, and the robot body is connected with the shelf body 1 through the front opening of the warehouse body, so that the connection and movement of the robot body and the shelf body 1 are realized, and the structure is simple and convenient to use. Meanwhile, the two feature plates 2 are symmetrically arranged on the left and right sides of the top plate 12, so that the two feature plates 2 are arranged on the left and right sides of the warehouse body, and the lateral position of the warehouse body is calibrated, so that the lateral position of the warehouse body is detected and aligned by the robot radar.

[0027] In combination Figure 4 In the embodiment, the identification feature rod assembly 3 includes an identification feature rod 32, which is arranged at the front end of the warehouse body and located between the two feature plates 2. In the initial state, the identification feature rod 32 is vertically suspended, and when the robot body enters the warehouse body, the radar on the robot body first detects the identification feature rod 32 to determine the central axis position of the front opening of the warehouse body, and then detects the positions of the two feature plates 2 to align the lateral positions of the robot body and the warehouse body, so that the positions of the robot body and the front end of the warehouse body are calibrated and aligned. After the robot position is calibrated, the robot body moves towards the warehouse body, and when the robot body touches the identification feature rod 32, the identification feature rod 32 rotates towards the inside of the warehouse body when the robot body continues to move inward, so as to avoid blocking the forward movement of the robot body.

[0028] In the embodiment, preferably, the end of the identification feature rod 32 is provided with a wheel groove 32a, and a roller 33 is rotatably installed in the wheel groove 32a through a shaft 32b. When the roller 33 touches the upper surface of the robot body, the roller 33 will roll towards the front direction of the robot body. The main function of the roller 33 is to reduce the friction of the identification feature rod 32 on the upper surface of the robot body and prevent scratching the upper surface.

[0029] In the embodiment, in order to facilitate the installation of the identification feature rod 32, the identification feature rod assembly 3 further includes a feature rod support 31 and a hinged support 34, the feature rod support 31 is fixedly installed on the top plate 12, the hinged support 34 is fixedly installed on the feature rod support 31, the top end of the identification feature rod 32 is rotatably installed on the hinged support 34, and the bottom end of the identification feature rod 32 passes through the installation groove 12a on the top plate 12 and is vertically suspended. Through the above arrangement, the feature rod support 31 is fixed with the top plate 12, and the identification feature rod 32 is rotatably connected with the hinged support 34 on the feature rod support 31, so as to facilitate the disassembly and installation of the identification feature rod 32.

[0030] In the embodiment, the characteristic rod support 31 is preferably a convex structure, and the fixing holes 31b are arranged on the wing plates 31a on both sides of the characteristic rod support 31, and the through holes are arranged on the top plate 12. In the assembly, the fixing holes 31b on the wing plates 31a on both sides of the characteristic rod support 31 are aligned with the through holes on the top plate 12, the bolt is penetrated through the fixing holes 31b and the through holes and is locked and fixed by the nut, so as to realize the fixation of the characteristic rod support 31, thereby facilitating the overall disassembly and assembly of the characteristic rod assembly 3.
