[0038] The principle of a four-speed manipulator transmission mechanism:
[0039] The motor seat, the upper main body and the connecting plate constitute the movable pulley structure of the upper speed lever;
[0040] The motor seat is used as a fixed point, and the driving motor provides the moving pulley structure with forward power, and pulls the upper active belt to move through the active pulley and the upper transition wheel, thereby driving the upper main body to move forward;
[0041] While the upper active belt drives the upper main body to move forward, the upper passive belt and the upper passive wheel are driven, so that the upper passive belt drives the connecting plate to move forward synchronously. At this time, the connecting plate produces a double speed displacement relative to the motor seat;
[0042] The connecting plate, the lower body and the bottom plate constitute the movable pulley structure of the lower speed lever;
[0043] When the connecting plate moves forward on the upper body, it provides power to the lower movable pulley structure, and pulls the lower body relative to the connecting plate through the lower transition wheel and the lower active belt to produce the same displacement in the same direction;
[0044] While the lower active belt drives the lower main body to move forward, the lower passive belt and the lower passive wheel are also driven to move, thereby driving the bottom plate to move forward. At this time, the bottom plate produces a double-speed displacement relative to the connecting plate. Similarly, the bottom plate produces a quadruple-speed displacement relative to the motor base, that is, the end picker can transport products at four times the speed, thereby improving work efficiency.
[0045] The beneficial effects of the four-speed manipulator transmission mechanism of the present invention are:
[0046] 1. Two sets of speed rod structures are used to form a four-speed structure, which provides four times the stroke in a limited space, effectively increasing the stroke length and movement speed;
[0047] 2. It provides the feasibility of high travel in a small space and improves work efficiency.
