1. When the advancing / retreating means is arranged so that the advancing / retreating shaft provided in the advancing / retreating means moves up and down and the vacuum pump is activated to adsorb the uppermost component in the component supply unit to the tip of the adsorption nozzle, Is lowered from the atmospheric pressure, the advancing / retreating axis rises, and the suction nozzle connected to the advancing / retreating axis picks up one component, takes it out from the component supply unit, and rises to stand by in the air. On the other hand, when the component is removed from the suction nozzle, the pressure of the hollow portion of the advance / retreat means is released to the atmosphere through the opening of the suction nozzle, and the advance / retreat axis is lowered by its own weight. Then, the tip of the suction nozzle comes into contact with the uppermost part surface in the component supply unit, the suction nozzle opening is shut off to the atmosphere, and the suction nozzle picks up the component and automatically takes it out from the component supply unit as described above. Wait at the required height position.
2. As described above, since the advancing / retracting shaft provided in the advancing / retreating unit automatically moves up / down simply by attaching / detaching the component adsorbed to the suction nozzle opening, a changeover valve, a valve changeover switch, compressed air or electricity is used. Since an actuator and control software are not required, the structure is simplified and an inexpensive pickup device can be provided.
3. Since the structure is simple, maintenance, inspection and repair are easy, and the operating cost is low.
4. If the vacuum pressure and the opening area of the suction nozzle are appropriately selected, the force to remove the component from the suction nozzle can be reduced, so that the component can be removed from the suction nozzle with one hand and then moved to the assembly site. Since the other hand can perform other work, the work efficiency is improved and the productivity is improved.

The operation of the above configuration will be described.
First, a component supply unit 8 in which a plurality of components 9 are stacked and placed at a required position facing the opening of the suction nozzle 4 by grasping the advance / retreat shaft 3 or the suction nozzle 4 by hand and raising the advance / retreat shaft 3 upward. When the hand is released from the gripping advance / retreat shaft 3 or the suction nozzle 4, the advance / retreat shaft 3 and the suction nozzle 4 are lowered by its own weight, and the opening of the suction nozzle 4 is placed on the uppermost part surface of the thin plate-like part 9. The lowering operation is stopped upon contact.

Next, when a vacuum pump start switch (not shown) is turned on, the vacuum pump 7 sucks and exhausts air from the hollow portion 2 of the advance / retreat means 1 and the hollow portion 4a of the suction nozzle 4 through the hollow passages 5 and 6. As a result, the pressure in the hollow portion 2 of the advancing / retreating unit 1 and the hollow portion 4a of the suction nozzle 4 is reduced to be lower than the atmospheric pressure, and the thin plate-like component 9 is adsorbed by the opening of the suction nozzle 4 and pushed to the atmospheric pressure. The advancing / retracting shaft 3 is raised and abuts against a stopper (not shown) to stop the raising operation.
As a result, the component 9 is held by the suction nozzle 4 and stands by at an aerial position at a required height.

In this way, the component 9 that is automatically taken out from the component supply unit 8 and stands by in the air is manually removed from the suction nozzle 4 and carried to a required site and assembled to the counterpart site.
At this time, when the component 9 is separated from the opening of the suction nozzle 4, the pressure in the hollow passages 5 and 6, the hollow portion 2 of the advance / retreat means 1 and the hollow portion 4 a of the suction nozzle 4 is released from the reduced pressure to the atmosphere, The advancing / retracting shaft 3 and the suction nozzle 4 are lowered, and the opening of the suction nozzle 4 is brought into contact with the uppermost part surface of the thin plate-like component 9, and the thin plate-like component 9 is sucked by the opening of the suction nozzle 4 as described above. At the same time, the advancing / retracting shaft 3 pushed to the atmospheric pressure automatically rises and comes into contact with a stopper (not shown) to stop the raising operation, and the component 9 stands by at an aerial position at a required height.

The feature of the present invention is that the advancing / retracting means 1 is disposed so that the advancing / retracting shaft 3 moves horizontally, and the coil spring 15 is disposed in the hollow portion 2 to automatically advance the advancing / retreating shaft 3. .
A second embodiment of the component pickup apparatus according to the present invention will be described with reference to FIG.

First, a component supply in which a plurality of components 9 are stacked and placed at a required position facing the opening of the suction nozzle 4 by grasping the advance / retreat shaft 3 or the suction nozzle 4 by hand and retracting the advance / retreat shaft 3 to the left. After the portion 8 is disposed, when the hand is released from the gripped advance / retreat shaft 3 or the suction nozzle 4, the advance / retreat shaft 3 advances to the right by the elastic force of the coil spring 15, and the opening of the suction nozzle 4 is a thin plate-like component. The advancing operation is stopped by abutting against the top part surface 9.

Next, when a vacuum pump start switch (not shown) is turned on, the vacuum pump 7 sucks and exhausts air from the hollow portion 2 of the advance / retreat means 1 and the hollow portion 4a of the suction nozzle 4 through the hollow passages 5 and 6. As a result, the pressure in the hollow portion 2 of the advance / retreat means 1 and the hollow portion 4a of the suction nozzle 4 is reduced to be lower than the atmospheric pressure, and the thin plate-like component 9 is adsorbed by the opening portion of the suction nozzle 4 and receives the atmospheric pressure. Thus, the coil spring 15 is compressed without being able to resist the retreating force of the retreating / retreating shaft 3, and the retreating shaft 3 retreats and comes into contact with a stopper (not shown) to stop the retreating operation.
As a result, one component 9 is taken out from the component supply unit 8 and stands by at an aerial position at a required height.

In this way, the component 9 that is automatically taken out from the component supply unit 8 and stands by in the air is manually removed from the suction nozzle 4 and carried to a required site and assembled to the counterpart site.
At this time, when the component 9 is separated from the opening portion of the suction nozzle 4, the pressure in the hollow portions 5 and 6, the hollow portion 2 of the advance / retreat means 1 and the hollow portion of the suction nozzle 4 is released from the reduced pressure to the atmosphere, and the coil spring 15 When the advancing / retreating shaft 3 and the suction nozzle 4 are moved forward by the elastic force and the opening of the suction nozzle 4 comes into contact with the top surface of the thin plate-like component 9, the thin plate-like component 9 is opened to the suction nozzle 4 as described above. The advancing / retracting shaft 3 that is attracted to and pushed by the atmospheric pressure automatically retracts and abuts against a stopper (not shown) to stop the retreating operation, so that one component 9 is taken out from the component supply unit 8 and is at a required aerial position. stand by.

  In the part assembling process, it is used as an apparatus for taking out thin plate-like parts stacked in multiple layers.
