Description

Technical Field

[0001] The utility model relates to a circuit board transfer device, in particular to a power unit of a transfer device that actuates to make a rotating shaft rotate, so that a rotating part can generate a rotating actuation and drive a connecting rod to move up and down. A support seat and a suction module located at the bottom side of the connecting rod also move in the vertical direction. The power unit composed of a motor can accurately control the rotation angle and then adjust the suction module to a predetermined height. Furthermore, the suction module has a vacuum suction attachment that can be attached to the surface of the circuit board. By controlling the vacuum attraction force, the force for grasping and releasing the circuit board can be accurately adjusted, and problems such as circuit board breakage or dropping during the transfer process will not occur. Background Art

[0002] A transfer machine is a tool used to transfer and stack objects, and can also perform operations such as displacing and stacking large plates to achieve the purpose of transferring the plates to the next processing station for processing.

[0003] Furthermore, transfer machines are often used in the transfer processing operations of circuit boards. During the process, the transfer machine often needs to adjust the transfer height according to the specifications, manufacturing processes, and workstation positions of the circuit boards. Conventionally, the transfer machine often adjusts the height of the clamping jaws for clamping the circuit board by telescoping two overlapping sleeves. However, this structure has two disadvantages: First, it is not easy to make a positioning structure for the two telescopic sleeves, that is, it is impossible to adjust the clamping jaws to a predetermined height. Second, it is not easy to control the clamping force when the clamping jaws clamp both sides of the circuit board. If the clamping is too tight, the circuit board may be damaged; on the contrary, if the clamping is too loose, the circuit board may fall during the transfer process. Based on the above-mentioned various disadvantages of the conventional transfer machine, those in this industry are expected to conduct research and improvement. Summary of the Utility Model
