Description

[0001]
BACKGROUND OF THE INVENTION
The present invention relates to an apparatus for loading various electronic components in a case that accommodates the electronic components.
[0002]
[Prior art]
As shown in FIGS. 1 and 2, the photo interrupter, which is a representative example of a cased electronic component composed of an electronic component and a case for accommodating the electronic component, includes two accommodating portions 1a, In 1b, a light emitting element 2 having at least a pair of lead terminals 2 'and a light receiving element 3 having at least a pair of lead terminals 3' are loaded facing each other (for example, JP, 7-94775, A, etc.).
[0003]
By the way, a plurality of light emitting elements 2 and light receiving elements 3 used in the photo interrupter having this structure are manufactured by lead frames A and B as shown in FIG.
[0004]
Therefore, conventionally, when assembling the photo interrupter, one of the light emitting element 2 and the light receiving element 3 manufactured by the lead frames A and B is separated from the lead frames A and B, and then this one light emitting element. 2 and the light receiving element 3 are changed in the downward direction, and then loaded into the housing portions 1a and 1b in the case 1 in the upward posture.
[0005]
[Problems to be solved by the invention]
Conventionally, in this assembly, when the light emitting element 2 and the light receiving element 3 are separated from the respective lead frames A and B, the portions of the lead terminals 2 'and 3' in the light emitting element 2 and the light receiving element 3 are clamped. In this state, the downward direction change and the loading into the case 1 are performed, so that there is a high possibility that the lead terminals 2 'and 3' in the light emitting element 2 and the light receiving element 3 are bent and deformed. In addition, there is a problem in that the structure of the apparatus is complicated, remarkably large and expensive.
[0006]
As described above, the present invention provides an apparatus in which the above-described problem does not occur when an electronic component separated from a lead frame is accommodated in a case after the direction is changed in the upside down direction. It is a technical issue.
[0007]
[Means for Solving the Problems]
In order to achieve this technical problem, claim 1 of the present invention provides:

Is provided. "
It was configured as follows.
[0008]
Further, claim 2 of the present invention provides
“A case for housing each electronic component is disposed between a location where the electronic component in the first lead frame is separated from the first lead frame and a location where the electronic component in the second lead frame is separated from the second lead frame. A first tunnel configured to allow the electronic component to pass therethrough is provided between the case and the first lead frame so as to be curved in a substantially semicircular shape upward, and at one end of both ends of the first tunnel. While the downward opening is located at a position directly above the electronic component to be separated from the first lead frame, a nozzle is provided below the nozzle so as to blow air into the downward opening of the one end. And a second tunnel configured to allow the electronic component to pass between the second lead frame and the second lead frame. The downward opening at one end of the two tunnels is located at a position directly above the electronic component to be separated from the second lead frame, and air is blown into the downward opening at the one end below this Provide a nozzle. "
It was configured as follows.
[0009]
[Operation and effect of the invention]
In this configuration, the electronic component cut off from the lead frame is blown into the downward opening at one end of the tunnel by the air jetted from the nozzle below it, and is directed in the upside down direction when passing through the tunnel by the air flow. Converted and loaded into the case from the downward opening at the other end of the tunnel.
[0010]
In other words, according to the present invention, the electronic component separated from the lead frame can be loaded in the case after changing the direction in the opposite direction without clamping the lead terminal portion of the electronic component. It is possible to greatly reduce the occurrence of bending deformation in the lead terminals of the components, and the structure of the device is remarkably simplified, and the miniaturization and the cost reduction can be reliably achieved.
[0011]
In particular, when configured as in claim 2, two electronic components can be loaded into one case at a time, so that the present invention can be applied to assembling the above-described photointerrupter with a great effect. Is demonstrated.
