Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to an apparatus for manufacturing small electronic devices, and in particular to a manufacturing apparatus for manufacturing small electronic devices, and in particular, for manufacturing a flexible printed electrical wiring board (referred to as a flexible printed circuit board), The present invention relates to a device for connecting a large number of parallel conducting wires (referred to as ``terminal'') to each other in unison.

Generally, the width of each conductor at the connection between both plates is Q, 6
~ o, ssw, and the conductor wires can be easily matched based on the hole or external shape, making it easy to mechanize in the case of mass production. However, with the miniaturization and high density of electronic devices in recent years, the number of conducting wires accommodated on one flexible board has reached several tens of percent, and the inside of the conducting wire has become thinner (about L4 = α1 -). The current situation is that the conductive wires on both boards do not match accurately using the hole reference or the outer shape reference, and the operator currently uses a magnifying key etc. to align the positions and perform tack welding.

When attaching both ends of a long 7-lexiple board to their respective predetermined positions on the printed circuit board, the relative posture of both ends of the board is different from when the board is placed flat, so the positions on the printed circuit board can be adjusted from the magazine case to the position on the printed circuit board in one process. Since it is almost impossible to do this, it is usually done manually by each individual, which is extremely inefficient.

SUMMARY OF THE INVENTION An object of the present invention is to provide an apparatus for taking out a long flexible board in a flat state from a magazine, feeding it in a predetermined posture and position onto a printed circuit board, and connecting the board.

Holding position, that is, X Y #' Table device is sent in a flat state.

One of the holding devices moves and rotates in a predetermined direction to match the relative posture between both ends of the flexible substrate with the relative posture on the printed circuit board. The XYI-table device is detected at each @ by the Senna device, and the XY0 table device is moved and adjusted until the images match. If the images match, the second set of holding arms of the robot receives the flexible board, places it on the printed circuit board, and connects it by welding.

By interposing the XY0 table device in the middle, it becomes possible to take out the flexible substrate from the magazine in a flat state and connect it to the printed circuit board in a predetermined posture, resulting in a significantly high efficiency.
