Feeding device suitable for flexible printed circuit boards

The present invention relates to a receiving device, and more particularly to a receiving device suitable for a flexible printed circuit board.

Referring to FIG. 1 , a general receiving device 1 is used for connecting front and rear ends of two rolls of flexible printed circuit boards. The receiving device 1 includes a platform 11 , a feeding roller 12 pivoted below the platform 12 , and a plurality of feeding rollers 12 . A guiding roller 13 pivotally disposed on the platform 11 is disposed on the platform 11 and disposed on the platform 11 at a distance from the first pressing member 14 of the platform 11 and the first pressing member 14 The second pressing member 15 and a top frame 16 disposed on the platform 11 for placing the tape roll. The platform 11 is formed with a groove 111 extending in a direction parallel to the feed roller 12 and the rotation axis of the guide rollers 13.

Referring to FIG. 1 and FIG. 2, the operation of the receiving device 1 is: a roll of a flexible printed circuit board 21 is sleeved on the feeding roller 12, and the feeding roller 12 and the guiding rollers 13 are used. Rotating so that the flexible printed circuit board 21 passes through the platform 11 in a direction A perpendicular to the slit 111. At this time, the first pressing member 14 and the second pressing member 15 are located on the flexible printed circuit board 21. Above, until the flexible printed circuit board 21 completely leaves the feeding roller 12, and the front and rear of the flexible printed circuit board 21 The ends are respectively located on both sides of the slot 111. At this time, the second pressing member 15 presses and fixes the flexible printed circuit board 21 downward as shown in FIG.

Referring to Figures 1 and 3, another volume of flexible printed circuit is followed. The plate 22 is sleeved on the feeding roller 12, and then the flexible printed circuit board 22 is transported according to the above steps until the front end of the flexible printed circuit board 22 passes through the slot 111 in the book feeding direction A. At this time, the flexible printed circuit The front and rear ends of the plates 21, 22 are vertically overlapped above the slit 111 as shown in FIG. 3, and the first pressing member 14 is pressed down to fix the flexible printed circuit board 22.
