Description

DETAILED DESCRIPTION OF THE INVENTION (Field of Industrial Application) The present invention relates to a printed circuit board feeding device that supplies stacked printed circuit boards one by one.

(Prior art) When processing a printed circuit board, for example to form a cut groove on the surface of a printed circuit board, it is necessary to feed the printed circuit board one by one to the processing machine. A conventional printed circuit board feeding device includes a carriage 102 having a suction cup 101 at the lower end, as shown in FIG.
using the suction cup 101 to suck the topmost printed circuit board 103 out of the stacked printed circuit boards 103, and in this state move the carriage 102 slightly upward and then move it in the direction of the arrow to remove the printed circuit board 103. Suction cup 1 in supply position
01, then return the carriage 102 in the direction of the arrow i, and repeat the same operation, thereby feeding the laminated printed circuit boards 103 one by one to the processing machine side. It is.

(Problem to be Solved by the Invention) However, conventionally, the laminated printed circuit boards 103 are
When supplying sheets one by one, it is necessary to move the carriage 102 back and forth between the stacked printed circuit boards 103 side and the printed circuit board supply side, and it is also necessary to repeatedly suck the printed circuit boards 103 with the suction cup 101 and release the suction. Therefore, it was difficult to supply the printed circuit boards 103 one by one at high speed. Further, the mechanism for reciprocating the carriage 102 and the device for suctioning and releasing the suction of the suction cup 101 are very complicated, and the manufacturing cost is also high.

In view of the above problems, the present invention has a simple structure and is capable of supplying printed circuit boards one by one at high speed.

(Means for Solving the Problem) The technical means of the present invention for solving this technical problem is that in a printed circuit board feeding device that feeds stacked printed circuit boards 4 one by one in the delivery direction, a drive shaft is provided. A pressure roller 9 is freely rotatably held around 44, and a kicker member 10 is disposed close to the pressure roller 9 and has a tip end protruding from the outer peripheral surface of the pressure roller 9,
The pressure roller 9 is pressed against the upper surface of the end portion of the stacked printed circuit boards 4 on the opposite side to the feeding direction by a spring 59, and the kicker member 10 is pressed against the top surface of the end portion of the stacked printed circuit boards 4 on the opposite side to the feeding direction. A pair of printed circuit boards 4 are rotatably driven around the drive shaft 44 so as to kick out the opposite end face in the delivery direction, and on the delivery side of the stacked printed circuit boards 4, a pair of printed circuit boards 4 sandwiched between the printed circuit boards 4 kicked out by the kicker member 10 are provided. A pair of clamping rollers 15 and 16 are provided, and the pair of clamping rollers 15 and 16 are driven to rotate in opposite directions so as to feed out the sandwiched printed circuit board 4 in the delivery direction.

(Function) The pressing roller 9 is pressed against the upper surface of the end of the printed circuit board 4 on the lifter 1 on the side opposite to the feeding direction by the biasing force of the spring 59. In this state, when a drive signal is input to the motor 50, the kicker member 10 rotates once in the direction of the arrow around the drive shaft 44 every time the drive signal is input, and the kicker member 10 rotates once in the direction indicated by the arrow.
The end surface of the uppermost printed circuit board 4 on the lid 1 on the side opposite to the delivery direction X is kicked out one by one in the delivery direction. At this time, when the tip of the kicker member 10 reaches the downward position A while rotating in the direction of the arrow, the tip of the kicker member 10
Since the kicker member 10 makes contact with the end face of the printed circuit board 4 and then rotates toward the rear position B, the printed circuit board 4 can be kicked out in the delivery direction while lifting one end side of the printed circuit board 4 by kicking out the kicker member 10. Then, as shown in FIG. 11, the printed circuit board 4
The side in the sending direction contacts the front outer circumferential surface of the lower holding roller 16, and rides on the outer circumferential surface of the roller I6.

At this time, even if the uppermost printed circuit board 4 and the lower printed circuit board 4 try to move in the delivery direction, the brush 81 prevents the lower printed circuit board 4 from moving.

Then, as the holding roller 16 rotates in the direction of arrow d, the end portion of the uppermost printed circuit board 4 in the feeding direction is sandwiched between the holding rollers 15 and 16.

In this case, the position where the kicker member 10 starts kicking the printed circuit board 4 is the lower position A, and at this position A, the amount of movement in the delivery direction X is the largest, and decreases toward the front position B. On the other hand, the position where the printed circuit board 4 rides on the clamping roller 16 is the front outer circumferential surface of the clamping roller 16, and as the clamping roller 6 rotates in the direction of arrow d, the amount of movement in the feeding direction X gradually increases. They have a growing relationship. Therefore, as shown in FIG.
) By kicking out the base i4, the printed circuit board 4 is moved largely in the feeding direction The printed circuit board 4 can be quickly floated, and as a result, together with the kicking of the printed circuit board 4 by the kicker member 10, the entire printed circuit board 4 can be smoothly floated relative to the lower printed circuit board 4. Moreover, since the upper side of the nipping roller 16 moves a large amount in the feeding direction X, the end of the printed circuit board 4 on the feeding direction
The printed circuit board 4 is sent out in the sending direction X between 5.16 and 16.

Therefore, the printed circuit board 4 can be sent out at high speed while being reliably suspended from the lower printed circuit board 4.

Note that when kicking out the printed circuit board 4 with the kicker member 10, the kicker member 10 receives resistance from the printed circuit board 4 against rotation in the direction indicated by the arrow, but this resistance is caused by rotation in the direction indicated by the arrow relative to the gear 48. As a result, the gear 48 receives a force from the gear 49 that rotates around the gear 49 in the direction of the arrow a, which causes the swinging member 8 to the pressure roller 9 to rotate around the support shaft 43. The roller 9 swings in the direction of the arrow a using the swinging force as a fulcrum, and the pressure roller 9 can be pressed downward toward the printed circuit board 4 more strongly. Therefore, when kicking out the printed circuit board 4, the pressing roller 9 does not become floating from the printed circuit board 4, and the smooth and reliable kicking out of the printed circuit board 4 by the kicker member 10 is not impaired.

(Example) Hereinafter, the present invention will be explained according to the illustrated example.
