[0029] It should be noted that the swing cylinder 2 used above is an existing device that can be purchased. The working principle of the swing cylinder is mainly to drive the output shaft to make reciprocating rotational motion within a certain angle range through compressed air. Specifically: Composition and structure: The swing cylinder is usually composed of a cylinder body, a stator, a rotor and blades. The stator and the cylinder body are fixed together, and the blades are connected to the rotor (i.e., the output shaft). There are two air ports on the cylinder body. By controlling the on-off state of these two air ports, the blades can be driven to drive the rotor to rotate. Working process: When compressed air is introduced from air port A and air port B is exhausted at the same time, the compressed gas pushes the blades and drives the rotor to rotate counterclockwise; conversely, when compressed air is introduced from air port B and air port A is exhausted, the rotor rotates clockwise. Application: The swing cylinder is widely used in occasions where objects need to be transferred, turned over, sorted, clamped, etc.
