technical field

The utility model relates to the technical field of automation equipment, in particular to an adjustable automatic FPC bonding machine.

Background technique

The FPC board is a flexible printed circuit board (Flexible Printed Circuit). Because it is soft and inconvenient to process, it is generally necessary to paste the FPC board on a relatively rigid carrier board first, and then perform subsequent processing. The traditional method generally uses manual work. Sticking the FPC board on the surface of the carrier board, in the actual processing process, the work efficiency is low and the production cost is high.

The disadvantages are: ① It is disclosed that the carrier board is transported through the belt conveyor line, and the FPC board is grabbed by the four-axis manipulator. Due to the different specifications and sizes of the FPC boards, the specifications and sizes of the carrier boards are also different, which cannot be well applied to FPC boards of various specifications and The carrier board has poor versatility; ② it is disclosed that the FPC board is directly mounted on the carrier board, there is no suction between the FPC board and the carrier board, or it is bonded by setting an adhesive between the FPC board and the carrier board, so that There will be problems such as the difficulty of peeling off the FPC board from the carrier board in the later stage, adhesive residue, etc., or the FPC board can be fixed by setting a unique structure on the carrier board, which will increase the design and processing cost.
