Description

TECHNICAL FIELD

[0002] FPCB is the full name of Flexible Printed Circuit Board, and is also called FPCB or FPC. It is a kind of printed circuit board with patterns made of flexible substrate. It is composed of insulating substrate and conductive layer, and there can be adhesive between the insulating substrate and the conductive layer.

[0003] At present, the alignment method of FPCB circuit board is manual alignment. The so-called alignment is to realize the circuit alignment of a large FPCB and another small FPCB. At present, most of them adopt manual alignment method. The specific steps are as follows: first, fix the large FPCB on the fixed table through the fixing needle or fixing pin (usually three), and then connect the small FPCB with one of the fixing needles or fixing pins for alignment by manual method, so as to realize the accurate alignment of the large FPCB and the small FPCB. Since the fixing needle or fixing pin is thin and sharp, the fingers will be pricked by the fixing needle or fixing pin every time the small FPCB is pressed on the large FPCB by the fixing needle or fixing pin. Moreover, the uneven pressure of manual operation can easily cause the difference of the alignment tightness of the large FPCB and the small FPCB, which will affect the product efficiency and yield in actual production process. In addition, since the small FPCB is small in size and light in weight, it is difficult to achieve accurate grabbing and positioning. It is easy to cause displacement when grabbing the small FPCB, which affects the accuracy of positioning. In view of this, we provide a FPCB soft circuit board suction nozzle.

[0004] The prior art discloses a FPCB soft circuit board suction nozzle, which comprises a suction nozzle fixing disc and a suction nozzle fixing seat, one end of the suction nozzle fixing seat is connected with a circuit board suction nozzle, the circuit board suction nozzle comprises a suction nozzle fixing head and a suction nozzle body, a vacuum pipeline is arranged at the center of the suction nozzle fixing disc, a gas passage connecting pipe is arranged at the top of the vacuum pipeline, a gas passage connecting valve is arranged on the gas passage connecting pipe, a first air pipe is arranged in the suction nozzle fixing seat, a vacuum control valve rod is arranged at the connection position of the vacuum pipeline and the first air pipe, and a second air pipe is connected with a first suction hole and a second suction hole.

[0005] Although the above patent can realize stable adsorption of the FPCB plate without deviation, the adsorption and grabbing are very stable, the connection between the FPCB plate and the suction hole is more firm, and the use is convenient and saves human resources, the suction nozzle cannot be replaced, and then the problem that the suction nozzle cannot be adsorbed due to the shape of the suction nozzle not matching the production of other types of plates.
