Abstract

PROBLEM TO BE SOLVED: To automatically recover a flexible printed circuit board after separation, by pressing the back of a flexible printed circuit board through the holes for isolation of a pallet, separating the board from the pallet, and holding the back of the board. SOLUTION: By the descending of a pin board 25, tips of positioning pins are inserted into holes of a pallet 2, and press pins 23 do not enter the holes of the pallet 2. By driving a cylinder 32 of a separation unit 8, a retaining board 40 of a transfer unit 9 is made to ascent, a sponge 39 is made to abut against an FPC mounting surface of the pallet 2, and the pin board 25 is made to descend. The press pins 23 push the FPC, which is separated from the pallet 2. The FPC mounted on the retaining board 40 is drawn out to the vacuum suction head side with an actuator 37. The FPC is sucked and held by a vacuum suction head fixed on the suction board. Therefore the flexible printed circuit board is automatically recovered with high working efficiency.

(Operation) Next, the operation of the above-described embodiment will be described. As shown in FIG. 2, the pallet 2 on which the FPC 1 is mounted and fixed is carried into the separating and conveying device by the carrying-in conveyor 5. The loaded pallet 2 is
The tip of the rod 17a of the cylinder 17 is moved by raising the rod of the cylinder 17 of the charging device arranged in the center of the carry-in conveyor 5 shown in FIG. 3 and moving the rodless cylinder 15 forward (to the right in FIG. 3). It is pushed by and is put into the reversing unit 6.

Then, the pallet 2 is inserted into the groove c provided in the side plates 18a and 18b of the reversing unit 6 shown in FIG. 4, and is pushed to the end point of the groove c. Further, by driving the rotary actuator 20, the pallet is inverted by 180 ° (in the direction of arrow A in FIG. 4).
By this reversal, the pallet 2 in which the FPC 1 is temporarily fixed with the adhesive is placed with the placing surface of the FPC 1 downward. The inverted pallet 2 moves up the rod 17a of the cylinder 17 in the discharging device having the same structure as the charging device shown in FIG. The sheet is discharged from the reversing unit 6 toward the carry-out conveyor 7.

Pallet 2 discharged from the reversing unit 6
Is conveyed to the bottom of the separation unit 8 by the discharge conveyor 7, and the forward movement is stopped by the protruding operation of the stop pin 35 attached to the rod of the stopper cylinder 34 of the separation unit 8 shown in FIGS.

Then, the operation of separating the FPC 1 from the pallet 2 is started. At this time, the support member 36 of the transfer unit 9
Is positioned directly below the pallet 2 by driving the actuator 37. In order to separate the FPC 1 from the pallet 2, first, the first step driving of the two-step cylinder 30 is executed to lower the pinboard 25. This pin board 2
In descending position 5, the tip end of the tapered shape of the two or more positioning pins 24 fixed to the pin board 25 becomes 2 of the pallet 2.
The pressing pin 23, which is shorter than the positioning pin 24, is inserted into the holes 3 of the pallet 2 or more, but does not enter the hole 3 of the pallet 2. Thereby, the pin board 2 of the pallet 2 by the positioning pin 24
The positioning with respect to 5 is made.

Next, the cylinder 32 of the separation unit 8 is driven to raise the support plate 40 of the transfer unit 9, and the sponge 39 attached to this support plate 40 is used as the FP of the pallet 2.
Touch the C1 mounting surface. And 2 step cylinder 3
The driving of the second process of 0 is executed to further lower the pinboard 25.

Then, the pressing pin 23 presses the FPC 1 and the FPC 1 is separated from the pallet 2. At this time, since the cylinder 32 is provided on the cylinder base 33 connected to the moving plate 26 via the connecting rod 31, the cylinder 32 descends in conjunction with the driving of the two-step cylinder 30, so that the supporting plate 40 Also descends.

When the pin board 25 is raised by the two-step cylinder 30 and the support plate 40 is lowered by the cylinder 32, the F separated from the pallet 2 is removed.
The PC 1 is delivered on the sponge 39 attached to the support plate 40 with the mounting surface of the electric component facing down. The pallet 2 from which the FPC 1 has been separated moves on the discharge conveyor 7 and is discharged by raising the stop pin 35 attached to the rod of the stopper cylinder 34 of the separation unit 8.

The FPC 1 separated from the pallet 2 and placed on the support plate 40 is the actuator 3 of the transfer unit 9.
7 pulls out from under the separation unit 8 to the vacuum suction head 10 side. At this time, the vacuum suction head 10 is driven by the actuator 11 to pull out the support plate 40.
It is located right above. Then, the suction board 46 is lowered by driving the cylinder 47, and the FPC 1 is moved by the vacuum suction pad 45 attached to the suction board 46.
Is held by suction.

After that, the suction board 46 is raised by the cylinder 47. Then, the actuator 11 is driven to move the vacuum suction head 10 onto the collection box 49. Here, the vacuum suction of the FPC 1 by the vacuum suction head 10 is released, and the FPC 1 is dropped into the recovery box 49,
FPC1 can be collected.

(Effects) As described above, since the surface of the FPC1 on which the electrical components are mounted is down, that is, the back surface of the FPC1 on which the electrical components are not attached is up, the FPC1 and the pad 2 are separated. Since the back surface can be suction-held by the vacuum suction head 10, the FPC 1 can be automatically collected by holding the vacuum suction head 10 on the actuator 11.

Further, since the positioning pin 24 positions the pallet 2 with respect to the pin board 25 immediately before the FPC 1 is separated from the pallet 2, the pressing pin 23 is used.
The FPC 1 can be separated without damaging the FPC 1.

Further, when the FPC 1 is separated from the pallet 2, the support plate 40 having the sponge 39 attached thereto is applied to the FPC 1, and the support plate 40 is also lowered in conjunction with the lowering of the pin board 25, which is impossible for the FPC 1. The smooth separation operation of the FPC 1 can be performed without applying any force.
