The identification device 2000 includes a transport assembly 10, a gripper assembly 200, a camera assembly 300, a processor (not shown), and a handling assembly 400, wherein the transport assembly 10 is the same as the transport assembly 10 of the automatic identification device 100 for carrying and transporting vials. Specifically, the conveying assembly 10 may include a plurality of supporting rollers arranged adjacently, and may be formed by a V-shaped belt, as long as the conveying of the medicine bottles is achieved, and is not limited herein. The holding component 200 is disposed at the terminal end 103 of the conveying component 10 for holding the medicine bottle after the direction recognition and adjustment, where the terminal end 103 refers to a position of the conveying component 10 closest to the holding component 200. The clamping assembly 200 comprises two symmetrically arranged first clamping members 60, and in a vertical direction (not shown) away from the conveying assembly 10, the two first clamping members 60 are arranged above the terminal end 103; in the direction perpendicular to the traveling direction X of the conveying assembly 10, i.e., the illustrated direction Z, two first clamping members 60 are respectively disposed on two sides of the terminal end 103, and the reserved distance therebetween is greater than the width of the conveying assembly 10. When the clamping action takes place, first clamping piece 60 can be along deviating from the vertical direction of conveying assembly 10 and perpendicular to conveying assembly 10's advancing direction X emergence removal, according to the size adjustment self position of waiting to discern the medicine bottle, guarantees that the center pin homoenergetic of waiting to discern the medicine bottle of different specifications can be held up to same height.

The camera module 300 includes a camera (not shown) and a supporting plate 3010, and the camera is fixedly disposed on the supporting plate 3010. In addition, a processor coupled to the camera assembly 300 is further disposed in the identification device 2000 for processing the captured image and identifying the specification parameters of the medicine bottle according to the captured image.

Through the manner, when the two first clamping pieces 60 clamp the medicine bottles to be identified, the positions of the first clamping pieces 60 can be adaptively adjusted according to the sizes of the medicine bottles in the vertical direction away from the conveying assembly 10 and the advancing direction X perpendicular to the conveying assembly 10, so that the central axes of the clamped medicine bottles with different sizes can be lifted to the same height, namely the height of the central axis of each medicine bottle relative to the terminal end of the conveying assembly is kept consistent; in addition, when the medicine bottles clamped by the first clamping piece 60 move to the shooting range of the camera, the position of the camera is fixed, so that the distance and the angle of the central axis of each medicine bottle relative to the camera can be kept consistent, namely, the processor can acquire the collected images at the same shooting distance and shooting angle, and the success rate and the efficiency of the medicine bottle specification identification process are improved.

Please continue to refer to fig. 7 and 8. In a specific implementation scenario, each first clamp 60 has a first surface 601 disposed opposite to the other first clamp 60, where the first surface 601 refers to a clamping surface 6011 and a bearing surface 6012 that are connected to each other in a direction perpendicular to the traveling direction X.

In the direction toward the conveying assembly 10, the interval between the clamping surfaces 6011 of the two first clamping members 60 gradually increases, and the interval between the two bearing surfaces 6012 gradually decreases, in other words, the bearing surfaces 6012 and the clamping surfaces 6011 form a V-shaped structure, each surface is tangent to the surface of the medicine bottle during the clamping process, and for the medicine bottles with different diameters, the medicine bottles can be supported to the position corresponding to the same central axis under the limiting action of the bearing surfaces 6012 and the clamping surfaces 6011. Through the above embodiment, the medicine bottle is clamped by the first clamping members 60 which are symmetrically arranged, so that the position of the central axis of the medicine bottle is kept unchanged relative to the first clamping members 60 in each clamping process.
