DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a board supply device used for supplying stacked printed boards to a mounting machine.

[0002]

2. Description of the Related Art A conventional substrate supply apparatus will be described below.

As shown in FIG. 5, substrates 2 directly stacked on a main body 11 are sucked one by one by a suction drive unit 6 by a suction unit 13 of an arm 12 which moves up and down in a direction indicated by an arrow A under a negative pressure. After being moved onto the substrate transfer surface 7 and the negative pressure of the suction unit 13 is released, the substrate is placed on the substrate transfer surface 7. With the above series of operations, the substrate 2 is supplied to the mounting line one by one.

[0004]

However, the above-mentioned conventional construction requires a series of operations of suction, ascending, releasing, descending, and there is a problem that there is a limit in shortening the supply tact per one sheet. Since the substrate 2 must be lifted by negative pressure suction, it is necessary to set the position of the suction portion 13 in the surface of the substrate 2, and when the shape of the substrate 2 changes when switching the substrate 2, the suction of the suction portion 13 is performed. There was a problem that the position had to be adjusted manually.

An object of the present invention is to solve the above-mentioned conventional problems, and an object of the present invention is to provide a substrate supply apparatus which shortens a substrate supply tact and does not require adjustment at the time of substrate switching.

[0006]

In order to achieve this object, a substrate supply apparatus according to the present invention is capable of being stretched upward.
Elastic body that has almost the same thickness as the substrate before being stretched
And a guide that can hold a plurality of the elastic bodies and move back and forth.
And a plurality of bases on which the guide plates are stacked.
The plurality of elastic bodies are disposed before and after a plate, and
And a plurality of elastic bodies are held in contact with the end faces of
The guide plate is stretched upward and the end face of the substrate is
A substrate separation unit for separating simultaneously at equal intervals of one by one the substrate by moving in a direction to push the, movable in the right and left
Holding the substrate enters the gap of the separated substrate
And shaped rack plate comb, a lift driving unit for lifting the rack plate to the substrate transport surface, before the substrate to the substrate transport surface
Comprising the substrate pusher for feeding a serial rack plate
And

[0007]

In this configuration, the elastic bodies are stretched upward while sandwiching the plurality of substrates from both sides with the elastic bodies extending in the stacking direction of the stacked substrates, and the respective substrates are separated one by one and the separated state is maintained. Then, the comb-shaped rack plate is pushed into the gap between the substrates and removed from the elastic body.

[0008]

An embodiment of the present invention will be described below with reference to the drawings.

[0009] As shown in FIG.
Board separating part 3 which can move in the direction sandwiching the elastic body 4 from both sides, a rack plate 5 which can move in a direction orthogonal to the moving direction of the board separating part 3, and the rack plate in the direction shown by the arrow B. It comprises a lifting drive unit 6 that raises and lowers and raises the substrate 2 on the same plane as the substrate transport surface 7, and a substrate push-out unit 8 that can move the substrate 2 of the rack plate 5 into the substrate transport surface 7 in a direction indicated by an arrow C. I have.

As shown in FIGS. 2 and 3, an elastic body 4 such as a leaf spring coated with rubber 9 and a side plate 10 are provided in the substrate separating section 3 so as to be in contact with the substrate 2. Are stretched in the direction indicated by the arrow D, whereby the substrates 2 are separated one by one. At this time, the guide plates 10 are moved from both sides of the substrate 2 in the direction indicated by the arrow E.
Is held down by the elastic body 4.

Then, after the rack plate 5 is pushed into the separated gap of each substrate 2, the substrate separation unit 3 is separated from the substrate 2, and the substrate 2 is moved together with the rack plate 5 by the lifting drive unit 6 on the transfer surface 7. Then, the substrates 2 are fed one by one to the substrate transfer surface 7 by the substrate push-out unit 8.

FIG. 4 shows a flowchart of this series of operations. As described above, according to the present embodiment, the substrate separating section 3 that can move the stacked substrates 2 from both sides in the direction of being sandwiched by the elastic members 4, and the elastic members 4 are stretched to separate the substrates 2 one by one. By providing the rack plate 5 to be pushed into the gap, the stacked substrates 2 can be separated without sucking the substrate 2 by the negative pressure, the supply tact of the substrate 2 can be shortened, and when the substrate 2 is switched, Adjustment of the suction position is unnecessary, and the tact time for switching the substrate 2 can be reduced.

[0013]

As is apparent from the above description of the embodiment, the present invention provides a substrate separating section for holding a plurality of stacked substrates by an elastic body and separating the substrates one by one at equal intervals. A rack plate that enters and holds a gap between the substrates, a lifting drive unit that lifts the rack plate to the substrate transfer surface, and a substrate pushing unit that sends the substrate from the rack plate to the substrate transfer surface, provides a substrate supply tact. An excellent substrate supply apparatus which can be shortened and does not require adjustment at the time of substrate switching can be realized.
