Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a component supply device, and more particularly to a component supply device capable of reliably taking out one of the leading electronic components sent in a line on a linear vibration feeder by vacuum suction. Regarding

[0002]

2. Description of the Related Art Generally, a vibrating bowl feeder is widely used for feeding electronic components stored in a hopper to a place of use. The electronic components stored in the vibrating bowl feeder are randomly sent from the inner side to the outer side by vibrating action along the spiral track. A linear vibrating feeder is connected to the outlet side of the vibrating bowl feeder, and electronic parts can be fed to a supply place apart from the vibrating bowl feeder.

[0003]

However, on the terminal side of the component supply device which automatically supplies electronic components and the like by using the above-mentioned vibrating bowl feeder, the electronic components which are vibrated and transported in a row are provided. One must be picked up surely and mounted on a necessary place such as a circuit board. Therefore, conventionally, one of the electronic components is separated by using a slide shutter that moves in a direction orthogonal to the transport direction of the electronic component, but the position of the leading electronic component is not uniform and the electronic component There was a problem that one could not be picked up reliably. SUMMARY OF THE INVENTION Therefore, an object of the present invention is to solve the problems of the above-mentioned conventional techniques and provide a component supply device capable of reliably taking out one of electronic components that are vibrated and transported in a row. is there.

[0004]

In order to achieve the above object, the present invention provides a linear vibration feeder for vibrating and transporting electronic components along a linear guide groove, and an exit side of the linear vibration feeder. A pair of gate claws that are openably and closably provided to open and close the guide groove with the claw tips, and the claw tips of the pair of gate claws are pushed open to invade and a group of electronic components on the linear vibration feeder Is provided with a suction head capable of sucking one of the heads of the above and a drive device for linearly reciprocating the suction head with a predetermined stroke.

[0005]

According to the present invention, a group of electronic components that are vibrated and transported in a line on the linear vibration feeder are a pair of gates.
After being stopped by the tip of the toenail, the suction head, which moves linearly in a reciprocating stroke, adsorbs and holds one of the leading electronic components, and immediately after that, the gate nail removes the remaining electronic components. It enters the top and temporarily stops the progress of electronic parts.

[0006]

Embodiments of the present invention will be described below with reference to the accompanying drawings. In FIG. 1, reference numeral 1 indicates a vibrating bowl feeder for vibrating and transporting randomly stocked electronic components.
The da 1 has a spiral track 2 for vibrating and transporting electronic components from the inside to the outside. The lower surface of the vibrating bowl feeder 2 is provided with a vibration generating device for imparting transportable vibration to the vibrating bowl feeder. This vibration generating device is known per se and is composed of a plurality of vibrating plate springs that support an electromagnet that generates electromagnetic vibrations and a bowl, and that converts them into rotational vibrations that are transportable, and a controller. On the outlet side of the truck 2, a pair of guide pins 3 and 3 are installed in parallel with each other with a minute gap. This guide pin 3,3
A linear vibration feeder 4 is installed at the exit end of the. The linear vibration feeder 4 has a feeder main body 5, and a pair of long holding plates 6, 6 are provided in parallel on the upper surface of the feeder main body 5 with a space therebetween. , 6, a linear guide groove 7 is formed, and the guide groove 7 is
It is formed by two rails 8, 8. As is well known, a vibrating device 10 including a vibrating electromagnet and a leaf spring is provided below the feeder main body 5, and when the electromagnet is excited, electronic components 11 on the rails 8 and 8 are mounted. Can be fed in the direction of arrow A by vibrating action.

A pair of L-shaped gate claws 12A. 12B is rotatable around the pivot pins 13A and 13B. Block 1
It is pivotally attached to 4A and 14B. These gate claws 12A and 12B are spring-biased in a closing direction by springs 15A and 15B in a direction in which their mutual toes can be attracted. On the other hand, on the outlet side of the linear vibration feeder 4, a suction head 16 for vacuum-sucking one of the most advanced electronic components 11 of the electronic components grouped in a line is arranged. Carriage 2 through bracket 18
It is stuck at 0.

The carriage 20 can be moved back and forth along a guide rail 21 by a predetermined stroke. On the carriage 20, a hook plate 22
Is fixed, and the tip of the piston rod of the drive piston cylinder device 23 is attached to the hook plate 22. Incidentally, a vacuum suction hose 24 is connected to the suction head 16 and the tip thereof is connected to a vacuum suction source.

Since the present invention is constructed in this way,
When the vibrating bowl feeder 1 is driven, a large number of electronic components 11 in the bowl are vibrated and transported from the inside to the outside along the track track 2 due to the transporting vibration action. The electronic component 11 exiting the exit side of the track truck 2 is
The legs are dropped between the guide pins 3 and 3 and are sent downstream in an upright posture. After that, the electronic component 11 moves to the guide groove 7 between the rails 8 of the linear vibration feeder 4 and is sent to the downstream side.

During this time, the electronic component 11 has its lower leg portion attracted by the permanent magnet 25 as shown in FIG. 2, and the vertical posture is maintained. In this way, the leading electronic component 11a of the electronic component group sent in a line in the upright posture is stopped at the tip of the gate claws 12A and 12B and placed in a standby state.

Next, the piston rod of the piston drive device 23 is retracted, and the carriage 20 is moved along the rail 21 along the arrow B along with this. Then, the suction head 16 is moved toward the gate claw 12, and the suction head 16 is moved to the gate claws 12A and 12B as shown in FIG.
The toe is pushed open to enter, and the leading electronic component 11a is sucked and held. After that, the piston rod of the piston cylinder device 23 moves in the opposite direction, and the suction head 16 moves backward while sucking and holding the leading electronic component 11a. Then, the electronic component 11 held by the suction head 16 in the retracted position
Drop a.

[0012]

As is apparent from the above description, according to the present invention, one of the electronic components can be sucked and held by the suction head which can be opened by pushing the gate claws open. It is possible to reliably take out one of a group of electronic components that are vibrated and transported above.
