[Industrial application field]

The present invention relates to a gravity chute type component supply device that separates and supplies portions with burrs on the front and rear ends of IC components, etc. housed in a stake, one by one.This invention is an improvement to specifically prevent separation defects due to component burrs. It is related to.

[Conventional technology]

A plurality of electronic components such as DIP type ICs are housed in a rod-shaped stay. Such a stake is attached to an electronic component insertion device or the like, and IC components are taken out one by one and inserted onto a printed circuit board. In such an electronic component insertion device, a gravity chute having a continuously inclined guide surface is provided on the stake containing the IC component, and the IC component is inserted through a separation means installed in the gravity chute.
Supplied separately. Conventional means of separation are
A stopper that can be opened and closed is provided at the front end of a plurality of ICs arranged continuously along the guide surface of the gravity chute, and when this stopper is opened, it presses and holds the second IC from the front on the guide surface. It has a holding means for This presser means allows the second
By opening the stopper while pressing and fixing the IC, only the frontmost IC is sent out along the gravity chute.

[Problem that the invention attempts to solve]

In the conventional IC component separation and supply device mentioned above,
Adjacent ICs overlap each other due to burrs generated at the front and rear ends of the IC component made of a molded body, causing 1
The burrs in front and behind the second IC overlap on the burr at the rear end of the second IC, and when holding down the second IC, the first IC is also held down through the burr, so even if the stopper is opened, the IC will separate and fall. In some cases, smooth supply of parts could not be achieved due to this. In order to solve this problem, as disclosed in Japanese Utility Model Publication No. 56-2672, it is known that a step is provided downstream from the guide surface on the bottom of the first part to separate the burrs. ing. However, even with this method, if the burrs are overlapped and entangled with each other, the weight of the first part alone will not separate the tangled burrs, and it is not possible to reliably separate and supply the burrs. There were also cases where there was no such thing.

In view of the above-mentioned shortcomings of the prior art, the present invention has developed a gravity chute type that can reliably take out and smoothly supply various parts with burrs one by one without causing separation failure due to overlapping of burrs of adjacent parts. The purpose is to provide a parts separation and supply device.

[Means for solving problems]

In order to achieve this objective, the present invention continuously arranges a plurality of parts with burrs in the front and rear directions along an inclined guide surface in a line in the front and back direction, and a part supplying part is provided at the front end of the part row. In a gravity chute type component separation and supply device comprising a stopper that can be opened and closed, and a holding means for pressing and holding the second component from the front on the guide surface when the stopper is opened, the second component A projection is formed by forming recesses on the front and rear sides of the guide surface below the stopping position of the component and in front of the pressing position of the holding means, and the recess on the rear side is the third The structural feature is that the length extends below the stopping position of the part and is at least longer than the length of the part.

[Effect]

If the second component located on the projection of the guide surface is pressed from above at the position of the recess, the front end of the second component will engage with the front end of the recess and the front end of the component will be lifted, and the first component will be lifted up. The rear end face of the part and the front end face of the second part will be misaligned in the vertical direction, and the orientation of the first and second parts will change, causing the parts with overlapping burrs to bend. Even in parts that are overlapped in a state where the burrs are entangled with each other, the engagement between the burrs is released.

〔Example〕

The drawing is a configuration diagram of an embodiment of the IC component separation and supply device according to the present invention. An inclined guide surface 2 constituting a gravity chute is fixed onto a main body frame member 1 of an electronic component insertion device. In front of this guide surface 2 (below)
An external guide member 3 is connected to the external guide member 3 for leading out the IC components taken out one by one. At the rear (above) of the guide surface 2, a stake 4 containing a plurality of IC components 5 is continuously attached to the guide surface 2. A stopper 6 that can be opened and closed in the vertical direction is provided at the front end of the guide surface 2 for supplying IC components. This stopper 6 is driven to open and close by a solenoid 7.
The figure shows a state in which the stopper 6 is opened upward. The actuator 8 of the solenoid 7 is connected to the stopper 6 by a pin 10 via a link 9. The stopper 6 is rotatably mounted around a pivot 12, and
The tip of the component is locked with the tip 6a bent into a letter shape. One end of a lever 11 is further pivotally connected to the link 9 by the same pin 10. The lever 11 is attached to the same pivot 12 as the stopper 6, and the other end engages with a locking piece 14 of a lever 13 for holding down parts.
A holding member 15 for pressing the IC component from above is fixed to the component holding lever 13. A spring 16 is engaged with the component holding lever 13, and always urges the holding member 15 toward the component. Stoppa 6
A protrusion 17 located forward of the holding member 15 is formed on the guide surface 2 on the lower surface of the second IC component 5b adjacent to the frontmost IC component 5b when the IC component 5a is closed. This protrusion 17 is located forward of the presser member 15. When forming the protrusion 17, the protrusion 17 is formed by cutting at least the rear side of the protrusion position on the guide surface 2, leaving the protrusion 17 and forming the recess 18. The recess 18 behind this protrusion 17 is made longer than the length of the IC component, and the third IC
The size is such that a part of the component 5c can enter.
If the direction of the first component and the second component is not changed or the amount of positional deviation is insufficient, a recess 18 may be formed in front of the protrusion 17 so that the first component can fit into the recess 18 in front. By entering the parts, the amount of change in orientation and positional shift of the parts increases, making it easier to separate them. Further, by forming gentle slopes at the front and rear of the protrusion 17, it is possible to prevent the feeding of the parts due to gravity from being obstructed.

When the solenoid 7 is driven and the actuator 8 is pulled up as shown by the arrow, the stopper 6 is rotated around the pivot 12 as shown by the arrow and pulled up via the rod 9, and the tip 6a is opened. As a result, the first IC component 5a slides down along the guide surface 2. At this time, the lever 11 rotates around the shaft 12, and its rear end descends as shown by the arrow. Therefore, the pressing member 15 presses the second IC component 5b via the lever 13 by the spring 16 and holds it fixedly on the guide surface 2. At this time, the front of the second IC component 5b is lifted by the action of the protrusion 17. Therefore, the burr A of the first IC component 5a
The burrs B of the second IC component 5b are bent and shifted in the vertical direction, and the burrs do not overlap with each other. Therefore, the first IC component 5a is smoothly sent out without causing separation failure due to the burrs getting caught. Also, the second IC component 5b
As for the third IC component 5c, by providing the recess 18 at the rear of the second IC component as in this embodiment, the rear end of the second IC component 5b is similar to that of the third IC component 5c. When moving from the position, it falls into the recess 18 of the guide surface 2, and the third IC
It stops at a position lower than part 5c. Therefore, the burr B' of the second IC component 5b and the burr C of the third IC component 5c are also vertically displaced. Therefore, when the solenoid 7 is released and the stopper 6 is lowered and closed by the operation opposite to the above, and at the same time the rear end of the lever 11 is raised to lift the presser member 15, the second IC component 5b moves smoothly to the first position. In addition, by releasing the engagement between the burrs of the first and second IC components in advance in this way, poor separation due to burrs can be more reliably prevented.

[Effect of idea]

As explained above, in the component separation and supply device according to the present invention, a projection is provided on the guide surface at the bottom of the second component, and the second component is pressed and held from above behind the projection. The rear end surface of the second component and the front end surface of the second component are bent to shift their positions, and the contact engagement between the burrs is released. Therefore, the first part can be smoothly sent out without causing separation failure. Furthermore, if the side surfaces of the protrusions are formed into gentle slopes as in this embodiment, the parts can be moved smoothly. In addition, since a recess is formed behind the protrusion so that a part of the third part can enter, the engagement between the burrs of the second and third parts is simultaneously released, preventing separation failure due to the burr. It is even more reliably prevented.
