DETAILED DESCRIPTION OF THE EMBODIMENTS
[0016] The following description is used to disclose the present utility model so that those skilled in the art can implement the present utility model. The preferred embodiments in the following description are only examples, and those skilled in the art can think of other obvious variations.
[0017] As Figures 1-4 shown, a label information recognition device includes a mounting frame 3, a second fixing frame 4, a motion camera 5 and two strip light sources 6. One end of the second fixing frame 4 is mounted on the top end of the mounting frame 3, and the other end of the second fixing frame 4 is connected to the motion camera 5. The strip light sources 6 are located below the motion camera 5. A first fixing frame 2 is provided on one side of the mounting frame 3. A first driving motor 7 and a ball screw 9 are respectively provided inside the first fixing frame 2. The movable end of the ball screw 9 is connected to the side surface of the mounting frame 3. Both ends of the ball screw 9 are mounted with fixing blocks 8 through bearings. The two fixing blocks 8 are mounted inside the first fixing frame 2. One end of the ball screw 9 is connected to the movable end of the first driving motor 7. By controlling the first driving motor 7 to be powered on and work, the first driving motor 7 controls the ball screw 9 to rotate. When the ball screw 9 rotates, the nut therein moves on the screw rod, which is convenient for the nut to drive the mounting frame 3 to move along the horizontal direction, and further controls the motion camera 5 to move synchronously along the horizontal direction, facilitating the motion camera to identify the label content with a longer length.
[0018] A long strip plate 1 is mounted at the bottom end of the mounting frame 3. One ends of the two strip light sources 6 are respectively mounted at both ends of the long strip plate 1. The long strip plate 1 can fix the positions of the two strip light sources 6. After the two strip light sources 6 are powered on, they generate light for illuminating the label, facilitating the motion camera 5 to identify the content on the label in a dim light environment.
[0019] A wire winding and unwinding shaft 12 is provided inside the second fixing frame 4. The side surface of the wire winding and unwinding shaft 12 is connected to a second driving motor 16. The bottom of the second driving motor 16 is mounted inside the second fixing frame 4 through a motor bracket. A guide shaft 15 corresponding to the position of the motion camera 5 is provided inside the second fixing frame 4. Both ends of the guide shaft 15 are mounted on two symmetric side surfaces inside the second fixing frame 4 through bearings. A rope 14 is wound around the surface of the wire winding and unwinding shaft 12. One end of the rope 14 slides along the surface of the guide shaft 15 and is connected to the top of the outer shell of the motion camera 5. When adjusting the motion camera 5 along the vertical direction, only need to control the second driving motor 16 to be powered on and work. The second driving motor 16 controls the wire winding and unwinding shaft 12 to rotate clockwise. During the rotation of the wire winding and unwinding shaft 12, the rope 14 is released from its surface. The motion camera 5 moves downward under its own gravity while tightening the rope 14. The descending height of the motion camera 5 is determined by the length of the rope 14 released, which is used to adjust the height position of the motion camera 5. The guide shaft 15 plays a guiding role for the rope 14, improving the smoothness of the rope 14 during the winding or unwinding process.
[0020] A fixing plate 13 is installed inside the second fixing bracket 4. A plurality of sleeves 10 are installed through the surface of the fixing plate 13. A sliding rod 11 is slidably installed inside the sleeve 10. The bottom end of the sliding rod 11 is installed on the top of the action camera 5. There are two sleeves 10, and the sleeves 10 are arranged symmetrically. The fixing plate 13 is used to fix the positions of the sleeves 10. The sliding rod 11 allows the sleeves 10 to slide inside it, playing a role in limiting the movement of the action camera 5, preventing the action camera 5 from horizontally shifting during movement, and improving the stability of the action camera 5 during vertical movement.
