Description

Technical Field

[0002] FPCB is short for Flexible Printed Circuit Board, also known as FPCB or FPC for short. It is a flexible printed circuit board, which is a printed circuit board with patterns made of a flexible substrate, composed of an insulating substrate and a conductive layer, and there may be an adhesive between the insulating substrate and the conductive layer.

[0003] For example, in the patent of a nozzle for FPCB flexible printed circuit board with the publication number CN201921984907.0, by vertically arranging the nozzle body and the nozzle fixing seat, it is convenient to adsorb the FPCB board. Through the first adsorption hole and the second adsorption hole set to adsorb the FPCB board, stable adsorption of the FPCB board can be achieved without offset, the adsorption and grasping are very stable, making the connection between the FPCB board and the adsorption hole firmer, convenient to use, and saving human resources.

[0004] In the above technical solution, when the adsorption hole contacts the flexible printed circuit board, since components are provided at some positions on the surface of some flexible printed circuit boards, the local surface is uneven. When the traditional vacuum nozzle is used for adsorption, it is necessary to avoid the uneven places of the flexible circuit board, which may cause uneven force and lead to curling of the flexible circuit board when it is put down, affecting the normal use of the flexible circuit board. At the same time, the adsorption hole is not provided with a buffer structure, and it is easy to damage the flexible printed circuit board during the adsorption process.

[0005] Therefore, it is necessary to design a nozzle for FPCB flexible printed circuit board to solve the above problems. Summary of the Utility Model
