[0002] The bottle mouth option steering linkage mechanism is a mechanical device used to control the opening and closing of the bottle mouth and realize the automatic steering of the bottle mouth. This mechanism usually consists of multiple parts, including a drive device, a steering device, and a bottle mouth device.

[0003] Alternatively, when the movement of the robotic gripper needs to be controlled, due to the constraints of the actual structural space, some specific routes need to be completed to avoid collision and motion interference of the robot.

[0004] Nowadays, when controlling the movement or linkage of the robot in the X-axis and Y-axis directions on a plane, some designs use a separate motor drive for the X-axis and a separate motor drive for the Y-axis. This undoubtedly increases the cost and requires a controller to accurately control the linkage of the X-axis and Y-axis, which is costly and prone to errors.

[0005] In mechanical design, what needs to be solved is how to design the linkage mechanism based on the avoidance route requirements of the "U"-shaped route. Utility Model Content

[0014] Optionally, the longitudinal moving assembly includes a longitudinal slider and a longitudinal slide rail, two pairs of the longitudinal slider and the longitudinal slide rail are provided and are parallel to each other, and the transverse slider and the longitudinal slider are fixed by an intermediate plate.

[0033] The rotating arm 4 and the rotating shaft of the motor 3 are fixed. The motor 3 adopts a servo motor 3. The driving mode of the motor 3 is to rotate 180 degrees forward and backward in a reciprocating cycle. It can be seen that the rotating arm 4 cooperates with the roller member 5 to complete the action, and the other end of the lateral moving component 7 is fixed with a steering manipulator 9. This scheme realizes that the steering manipulator 9 moves in the path of the "U"-shaped path groove 22. Combined with Figure 2 As described, the bottle mouth option (bottle mouth workpiece) is moved from the track 13 to a suitable position. Through this solution, the steering robot 9 can pick up the workpiece, and then move the workpiece away to avoid the slide rail and put it into another slide rail in the vertical direction.
