Description

The present invention relates to an electronic component handler used to sort out electronic components such as ICs according to their quality, for example.

FIG. 1 is a front view of a conventional example. This electronic component handler 1 is provided with one vertically oriented loading chute 2. A sorting chute 3 is swingably connected to the terminal end of the charging chute 2, that is, the lower end in the figure, with the upper end thereof as the center. The terminal end of the sorting chute 3 is selectively turned to the starting ends of the three take-out chutes 4 provided on the lower side thereof. The electronic component handler 1 swings the sorting chute 3 to move the electronic component from the loading chute 2 to the sorting chute 3.
The desired take-out chute 4 can be guided via the. However, in such a conventional electronic component handler 1, when the swing angle of the sorting chute 3 is increased, the electronic component is caught at the connecting portion between the charging chute 2 and the sorting chute 3, and the angle is limited. For this reason, the selection chute 3 has no choice but to be long, and there is a problem that the size is increased.

An object of the present invention is to solve the above technical problems and to provide an electronic component handler that can be downsized.

Hereinafter, embodiments of the present invention will be described in detail with reference to the drawings. FIG. 2 is a front view of an embodiment of the present invention. The electronic component handler 5 includes one charging chute 6 extending in the vertical direction, a selection chute 7 connectable to the end of the charging chute 6, and two selection chutes 7 selectively connected to the end of the selection chute 7. Equipped with ejection chutes 8 and 9. One take-out chute 9 is on the same axis as the throw-in chute 6,
The other ejection chute 8 extends horizontally or substantially horizontally. In this embodiment, non-defective products of the electronic parts from the charging chute 6 are fed to one ejection chute 9, and defective products are fed to the other ejection chute 8.

A guide groove 11 for guiding the electronic component 10 is formed in the loading chute 6 in the longitudinal direction (vertical direction in FIG. 2), and the selection chute 7 and the ejection chutes 8 and 9 similarly have the guide grooves 12 ,. 13 and 14 are formed respectively. These guide grooves 11,1
2, 13 and 14 are formed so as to conform to the shape of the electronic component 10, and are of a cubic shape, in which a large number of lead wires are juxtaposed in a line at the center of one surface of the electronic component of this embodiment. Parts 10
In this case, these guide grooves 11 to 14 are formed in an inverted T shape. In the injection device 16 as a feeding means extending in the same axial direction as the other take-out chute 8, the sorting chute 7 is angularly displaced and connected to the other take-out chute 8, that is, as shown in FIG. In this state, the electronic components in the sorting chute 7 are fed to the other ejection chute 8 by injecting air.

The sorting chute 7 is supported by a disc-shaped support 15 capable of angular displacement, and is angularly displaced integrally with the support 15. The support 15 is angularly displaced about 90 degrees around the center 0 of the sorting chute 7 as indicated by arrows 22 and 23. The peripheral edge of the support body 15 and both ends of the selection chute 7 are in sliding contact with the main body 24 of the electronic component handler 5, and the main body 24 is only the part facing the input chute 6, the ejection chutes 8, 9 and the feeding means 16. An opening is formed in the input chute 6
The electronic component 10 fed from the inside to the sorting chute 7 is fed to either the ejection chute 8 or 9 from the opening. As shown in FIG. 2 a, the sorting chute 7 is normally located at a position where its axis coincides with the axis of the charging chute 6, that is, at a position where the axis extends in the vertical direction. When 10 is fed, it is angularly displaced to a position where its axis extends horizontally as shown in Figure 2b.

An opening / closing means 17 for opening / closing the connection with the sorting chute 7 is provided in the passage 25 of the electronic component above and adjacent to the starting end of the one ejection chute 9. The opening / closing means 17 is driven to expand and contract in the horizontal direction (left and right direction in FIG. 2) by a drive cylinder 18 so that one of the take-out chute 9 and the sorting chute 7 is moved.
Opens and closes the connection with. In the opening / closing means 17, the axes of the charging chute 6, the selection chute 7 and the one ejection chute 9 coincide with each other, and the electronic parts that are non-defective are the selection chute 7.
Only when it is fed into the inside, the withdrawal from the passage 25 of the electronic component is made, and the sorting chute 7 and one ejection chute 9 are connected. As a result, the non-defective electronic component in the sorting chute 7 reaches the inside of the one ejection chute 9 by its own weight.
In other cases, the opening / closing means 17 shuts off the passage 25 of the electronic component, which may cause the electronic component in the sorting chute 7 to be caught in the passage 25 when the sorting chute 7 is angularly displaced. It is prevented.

As shown in FIG. 2A, a photo sensor 19 is provided near the starting end of the sorting chute 7 to detect whether or not the electronic component 10 has passed through the sorting chute 7, and the pickup chutes 8 and 9 are also the same. Photo sensors 20 and 21 are provided respectively. Further, control means (not shown) for controlling the operations of the support body 15, the feeding means 16, and the opening / closing means 17 based on the outputs of these photosensors 19, 20, 21 are provided.

Next, the operation of the electronic component handler 5 thus configured will be described. When the photo sensor 19 detects that the electronic component 10 has been fed from the charging chute 6 to the sorting chute 7 as shown in FIG. 2A, if the electronic component 10 is a good product, the opening / closing means The electronic component 10 is withdrawn from the passage 25 of the electronic component 10, and the non-defective electronic component 10 is thereby fed to the one ejection chute 9. When the electronic component 10 fed from the charging chute 6 to the sorting chute 7 is defective, the support 15 is angularly displaced in the direction of the arrow 22 to the state shown in FIG. Is ejected, so that the defective product in the sorting chute 7 is fed to the other ejection chute 8. After the photo sensor 20 detects that the electronic component 10 has been fed to the other ejection chute 8, the ejection of air from the ejection device 16 is stopped and the sorting chute 7 is returned to the original state shown in FIG. 2a. Return to the state. After the photosensors 19, 20, 21 detect that the electronic component 10 has passed through the chute in this way, the angular displacement of the sorting chute 7 and the operation of the opening / closing means 17 are performed, so that the electronic component 10 is caught as in the conventional case. Never.

As described above, according to the present invention, the sorting chute is supported by the support capable of angular displacement, and by the angular displacement of the support, the selection chute and the ejection chute are connected, and one ejection chute is the same vertical as the charging chute. On the axis, an opening / closing means for opening and closing the connection with the selection chute is provided in the vicinity of the start end of the one extraction chute, and the other extraction chute extends in the horizontal or substantially horizontal direction. Since the feeding means for feeding the electronic components in the sorting chute in a state of being connected to the sorting chute is provided, it is not necessary to lengthen the sorting chute as in the conventional case, and the electronic component handler can be miniaturized. It will be possible.

In particular, one take-out chute is provided on the same vertical line as the throw-in chute, the other take-out chute extends horizontally, and the other take-out chute is connected to feed the electronic parts in the sorting chute. Since the means is provided, the electronic parts are moved to the take-out chute side provided on the same vertical line as the throw-in chute by its own weight, and the electronic parts are moved to the take-out chute positioned in the horizontal direction by the feeding means. By doing so, it is possible to obtain a practical electronic part handler in which the electronic parts can be smoothly moved from the selection chute to the ejection chute in both directions by a structure without waste.
