[0017] The embodiments of the present invention are described in detail below. Examples of the embodiments are shown in the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain the present invention, but should not be construed as limiting the present invention.

[0018] Please see Figures 1-4 ,in, Figure 1 This is a schematic diagram of the visual positioning structure for positioning vials according to this utility model. Figure 2 This is a side view of the visual positioning structure for vial positioning according to this utility model. Figure 3 This is the utility model Figure 2 AA-line sectional view, Figure 4 This is the utility model Figure 3 A schematic diagram of the structure at point B.

[0019] This utility model provides a visual positioning structure for vial positioning, including a camera 1, a fixed shell 2, a fixed ring 3, a ring light 4, a fixing component, and an adjustment mechanism. The adjustment mechanism includes a fixed shaft 5, a motor 6, a lead screw 7, two limit blocks 8, and a sleeve 9. The fixing component includes a locking block 10, a limit piece 11, and a fixed rail 12. The aforementioned solution solves the problem that traditional vial positioning relies heavily on mechanical clamps or manual operation, and is easily affected by mechanical deviations, vial deformation, or placement posture, resulting in low positioning accuracy.

[0020] In this specific embodiment, the fixing shell 2 is bolted to the camera 1 and covers the outside of the camera 1. The fixing ring 3 is located outside the camera 1. The ring light 4 is bolted to the fixing ring 3 and is located below the fixing ring 3. The fixing component is located on one side of the fixing shell 2. The adjusting mechanism is located below the fixing component. The distance between the ring light 4 and the camera 1 is adjusted by the adjusting component. The ring light 4 illuminates the vial. The camera 1 captures the image of the vial mouth. The image processing algorithm is used to extract the edge of the vial mouth and fit the center coordinates. Finally, the coordinate data is transmitted to the host computer through a communication protocol to achieve precise positioning control of automated equipment (such as robotic arms and filling equipment).

[0021] The fixed shaft 5 is bolted to the fixed ring 3 and is located on one side of the fixed ring 3. One end of the sleeve 9 is fixedly connected to the fixed assembly, and the other end of the sleeve 9 is slidably connected to the fixed shaft 5 and covers the surface of the fixed shaft 5. The motor 6 is fixedly connected to the sleeve 9 and is located inside the upper end of the sleeve 9. One end of the lead screw 7 is fixedly connected to the output end of the motor 6, and the other end of the lead screw 7 is threadedly connected to the fixed shaft 5 and is located below the motor 6. The motor 6 drives the lead screw 7 to rotate, and the fixed shaft 5 moves on the surface of the lead screw 7, so that the lengths of the fixed shaft 5 and the sleeve 9 change accordingly to control the distance between the ring light 4 and the camera 1.

[0022] Secondly, grooves are provided on both sides of the fixed shaft 5, and two limiting blocks 8 are fixedly connected to the sleeve 9 and respectively set inside the corresponding grooves. The limiting blocks 8 move inside the grooves. When the motor 6 drives the lead screw 7 to rotate properly, the limiting blocks 8 are locked inside the grooves to prevent the fixed shaft 5 from rotating and to prevent the fixed shaft 5 from disengaging from the sleeve 9.

[0023] Secondly, the fixed rail 12 is fixedly connected to the fixed shell 2 and is located on one side of the fixed shell 2. One end of the locking block 10 is fixedly connected to the fixed shaft 5, and the other end of the locking block 10 is slidably connected to the fixed rail 12 and is located inside the sliding rail. During installation, the locking block 10 is inserted into the interior of the fixed rail 12, and the locking block 10 and the fixed rail 12 are fixed by bolts.

[0024] In addition, the limiting piece 11 is slidably connected to the fixed rail 12 and is located below the fixed rail 12. The setting of the limiting piece 11 restricts the position of the locking block 10, which improves the accuracy of the installation of the fixed shell 2.

[0025] When using this utility model, the motor 6 drives the lead screw 7 to rotate, and the fixed shaft 5 moves on the surface of the lead screw 7, so that the lengths of the fixed shaft 5 and the sleeve 9 change accordingly to control the distance between the ring light 4 and the camera 1. The ring light 4 illuminates the vial, and the camera 1 captures the image of the vial mouth. The image processing algorithm is used to extract the edge of the vial mouth and fit the center coordinates. Finally, the coordinate data is transmitted to the host computer through a communication protocol to realize the precise positioning control of automated equipment (such as robotic arms and filling equipment).

[0026] The above-disclosed embodiments are merely one or more preferred embodiments of this application and should not be construed as limiting the scope of this application. Those skilled in the art can understand that all or part of the processes for implementing the above embodiments and equivalent changes made in accordance with the claims of this application still fall within the scope of this application.
