[0002] The suction heads of chip components play a crucial role in the operation of SMT (Surface Mount Technology) pick-and-place machines. They are the most complex and core parts of the program application and components on the pick-and-place machine. Similar to a person's hand, they are responsible for completing the "pick-up - move - position - place" operation of components from the tape to the PCB circuit board. Some of the existing suction heads for chip components adopt the method that the suction port of the suction head is a horizontal round opening to achieve the suction of chip components. The limiting effect on the chip components during suction is poor, and the chip components are prone to rotation during the transfer process, which may affect the subsequent chip placement accuracy of the chip components.

[0006] Further, the rotation prevention mechanism further includes a baffle, and the baffle is fixedly connected to the rear end of the lower surface of the fixed seat. A rib groove is provided between the baffle and the arc-shaped seat to provide longitudinal limitation for chip components.

[0007] Further, a first reinforcing cylinder is fixedly connected to the upper end of the outer surface of the air cylinder, a second reinforcing cylinder is fixedly connected to the middle of the outer surface of the air cylinder, and a third reinforcing cylinder is fixedly connected to the lower end of the outer surface of the air cylinder, effectively improving the firmness of the suction head.
