Claims

[Scope of utility model registration request]

It has multiple arms, and a vacuum suction part is attached to the tip of the arm to take out and place the workpiece by vacuum suction and vacuum break.The arm rotates and moves up and down to attract, move, and place the workpiece. In a rotary pick-and-place unit, the fixed shaft at the center of arm rotation has a first through hole and a second through hole for evacuation, and a vacuum break at the top and bottom of the arm, as well as during rotation and movement. The first through hole and the second through hole provided in the central fixed shaft are connected to the vacuum groove on the outer surface of the fixed shaft, and the second through hole is connected to the vacuum groove on the outer surface of the fixed shaft. The vacuum groove extending downward from the hole is configured to be switched and connected to the vacuum breaking groove along the outer periphery extending from the third through hole, and the through hole provided in the bearing rotates around the fixed shaft around the fixed shaft. The air supply arm is connected to the vacuum part attached to the tip of each arm, and the air supply arm connected to the bearing, and the tube provided inside the slide shaft are connected to the first through hole when the arm rotates and moves up and down due to the rotation of the motor and the cam. The arm located at the position connected to the second through hole and the vacuum groove position supplies suction air to the vacuum part, and when the arm position is at the third through hole position and the vacuum break groove is at the lowest end, the groove A rotating pick-and-place unit characterized by being configured to automatically switch from vacuum suction to vacuum break to perform workpiece suction, movement, and placement operations.
