．． The clamper is used to press down the upper surface of the circuit board 1 placed on the circuit board 1, but the intermediate clamper is movable in case it collides with the component A protruding from the circuit board 1.

55 and 56ij, cylinders 057 installed on the movable frame 33.34 to operate the above-mentioned clampers 51 and 52, respectively, transport the circuit board 1 sent out from the board receiving frame 43°4.4 to the next process. - The width of the chain conveyor can be adjusted to match the width of the circuit board 10. Next, the operation of the above embodiment will be explained with reference to (a), (b), (c), and (b) of FIG. 4.

First, in the preparation work, as shown in FIG.
and 34.

When the positioning cylinders 29 and 30 are operated, their pistons move forward and press the plates 39 and 40, respectively, thereby positioning the plates 39 and 40 and fixing the shafts 35 and 36. Also, loosen the setscrew 38 of one movable frame 34 and remove the frame 34.
is in a movable state, and one board support frame 4 is placed in a movable state.
3 as a reference, move the other board support frame 44 together with the movable frame 34 to match the width of the circuit board 1, and then move the movable frame 34 to the axis 35°36 with the setscrew 38.
Fix K. Then, by operating the cylinders 47 and 48 provided on the movable frame 33 and 34 and moving the pistons forward, as shown in FIG.
Both board support frames 43 and 44 are respectively moved to the movable frame 33.
34 and slide away from both stepped portions 45 and 46.
The distance between the circuit board 1 and the circuit board 1 is made somewhat wider than the width of the circuit board 1.

On the other hand, the carrier 2, which supports the circuit board 1 from four directions by support pieces, is conveyed by the conveyor 12 in the direction of the arrow, stopped by a stopper 13, and positioned by a stopper 14 for positioning. , and both substrate receiving frames 43 .
The circuit board 1 supported by the carrier 2 moves up the tilting part 25 in which the parts 44 and 44 are held apart, and the stepped parts 45 and 46
Correspond to around 0.

Therefore, as shown in FIG. 4B, the pistons of the positioning cylinders 29 and 30 are moved back to free the shafts 35 and 36.

Next, the movable frames 33, . When both board receiving frames 43, 44 are returned to their original positions using cylinders 47, 48 provided at the step 45.
The interval 46 becomes the width of the circuit board 10, and the periphery of the circuit board 1 rests on the stepped portions 45 and 46. At this time, if there is a positional deviation between both 1 and 45.46, the shaft 35.
36 is free, so the board receiving frame 43.44 and the movable frame 33.34 slide to absorb this.

When this positional deviation is corrected, the clamper 41 is activated by the cylinder 42 [2], the shaft 35 is fixed, and the board receiving frame 43 is
．． 44 mag is immovable.

Further, the clampers 51 and 52 are rotated by the cylinders 55 and 56, respectively, and the circuit board 1 on the stepped portions 45 and 46 is clamped by the hooks 1151a and 52&. On the other hand, the cylinder 18 lowers the pushing member 15°16, presses down the lever pressurizing part, rotates the holding shaft 4°5, and retreats the supporting pieces 6.7 outward, thereby supporting the circuit board 1. To cancel.

Therefore, the slanting portion 25 is moved to the carrier 2 by the cylinder 24.
Then, the tilting portion 25 is lowered by the cylinder 27 provided on the main body base 19.

At this point, the pushing members 15 and 16 mentioned above rise, and the holding shaft 4
．． 5 returns to the original position.

On the other hand, when the tilting part 25 descends as described above, the clamping of the circuit board 1 by the clampers 51 and 52 is released, and the clamping of the shaft 35 by the clamper 41 is released. ), the pistons of the positioning cylinders 29 and 30 move forward again to the positioning plate 39.
．． 40 and fixing the shafts 35 and 36, the circuit board 1 placed on the steps 45 and 46 of the board receiving frame 43 and 44 is aligned with the transport position of the delivery chain conveyor 57.

The rear side of the circuit board 1 is pushed by the pushers 22 of the advancing pusher cylinder 23 and delivered onto the delivery chain conveyor 57, and after delivery, the cylinder 23 returns to its original position.

Thereafter, the transfer unit 25 horizontally slides diagonally to the left and returns to the original position #, thereby completing the process of receiving the circuit board 1 from the carrier 2 and the process of delivering it to the delivery conveyor 57. As shown in FIG. The space between the stepped portions 45 and 46 can be adjusted according to the width dimension of the circuit board 1, and the circuit board 1 when held in the carrier 2 is A pair of board receiving frames 43 and 44 configured to automatically adjust the positional deviation between the two frames 43 and 44, and a clamper that is provided on the frames 43 and 44 and is capable of freely clamping the circuit board 1 placed on the stepped portions 45 and 46. 51.52, a bushing cylinder 23 for feeding out the circuit board 1 placed on the above-mentioned step fils 45.46, and a cylinder 23 for conveying the sent out circuit board 1 and adjusting its width to match the width of the circuit board 1. It is composed of two possible chain conveyors 57 and 1.

Therefore, it is possible to absorb the positional deviation between the circuit board 1 supported by the carrier 2 and the board receiving frame 43, 44, so that the circuit board 1 can be reliably taken out without damaging the carrier 2. In addition, the board support frame 4
3, 44 step part 45.

46 and the width of the chain conveyor 57 for delivery can be adjusted according to the width dimension of the circuit board 1, so that the circuit board 1 after being taken out from the carrier 2 can be delivered to the chain conveyor 57 with accurate positional accuracy. This makes it possible to adapt to automation. Furthermore, since the circuit board 1 is placed on the step portions 45 and 46 of the board support frame 43 and 44, it can be applied to a circuit board 1 inserted with circuit components protruding from the periphery.
