Description

Printed circuit board loading device {APPARATUS FOR CARRYING OF PRINTED CIRCUIT BOARD}

The present invention relates to a printed circuit board loading apparatus.

Printed Circuit Board (PCB) serves to easily connect various electronic device elements according to a certain standard, and is widely used in all electronic products from home appliances to advanced communication devices. It can be classified into a PCB, a PCB for a package, and the like.

In such a printed circuit board, a thin plate such as copper is attached to one side of a phenol resin insulating plate or an epoxy resin insulating plate, and then etched according to the wiring pattern of the circuit (hereinafter referred to as “pattern”) to configure the necessary circuit and to assemble the parts. It is formed by drilling a hole for attachment and mounting, and may be classified into a single-sided board, a double-sided board, a multi-layer board, etc. according to the number of wiring circuit surfaces.

Printed circuit boards are used in high-precision products because the more the number of layers of the board is, the better the component tension is. When such a printed circuit board is completed, it is put in a box by size and transferred to an inspection process or a final assembly process.

As such, frequent movement between processes is required when manufacturing a printed circuit board product, which causes physical impact and friction on the printed circuit board, which may be a major cause of poor handling of the printed circuit board.

Recently, in order to reduce the handling defect rate of printed circuit boards, a method of automatically loading printed circuit boards in a loading facility using a separate loading device has been applied.
