DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS A first embodiment of the present invention will be described with reference to the drawings. FIG. 1 is a perspective view showing a first embodiment of the present invention, and FIG. 2 is a plan view of FIG.
The electronic component positioning device 1 has a long side direction X and a short side direction Y
And a relatively thick base metal plate 3 and a relatively thin positioning metal plate 2 having a plurality of portions for positioning the package P for electronic components on the base metal plate 3. . That is, the base metal plate 3 and the positioning metal plate 2 constitute a frame.

In this embodiment, the base metal plate 3 has a thickness of 1 mm.
The positioning metal plate 2 is made of about 0.3 mm thick stainless steel (for example, SUS-304). The positioning metal plate 2 has a plurality of portions for positioning the electronic component package P, and each portion includes a positioning portion 21 formed in a planar concave shape for fixing and mounting the electronic component to be positioned, It is composed of two elastic arms 22, 22 that extend in a direction away from each other from both ends of the positioning portion and are curved and approach each other, and a pressing portion 23 that connects the tips of the extended elastic arms 22, 22. The package p is surrounded by these components. The pressing portion 2 is provided at the center of the pressing portion 23.
3 is provided with an insertion hole 23a to be used when moving 3. Further, the pressing portion 23 is formed with slope portions 24, 24 that are in contact with the two corners of the electronic component package P. Both ends of the slopes 24, 24 need to be outside the corners P1, P1 of the package P, and the width is gradually reduced toward the central portion where the insertion hole 23a is located. .

The distance between the surface where the electronic component positioning portion 21 and the pressing portion 23 face each other (more precisely, the distance between the inclined portion formed on the pressing portion and the portion expected to come into contact with the package at the time of pressing and fixing). Is set to be smaller than the dimension in the direction in which the electronic components to be installed are sandwiched (the long side direction X in this embodiment) in a normal state. Thereby, the elastic force of the elastic arms 22 and 22 acts as a force for pressing (clamping) the electronic components to be installed. The adjustment of the pressing force may be set by the size, material selection, thickness, etc. of the elastic arm. The processing of these parts can be easily performed by using a press processing or a photo etching technique.

In this embodiment, the thickness of the positioning metal plate 2 is 0.3 mm. Depending on the material used, it is necessary to select a thickness or the like for making the elastic force (pressing force) of the elastic arm appropriate. There is.

In this embodiment, at least part or all of the elastic arm 22 may be thinned. With such a configuration, the distortion of the elastic arm that is deformed when the package P is installed on the positioning device or when the package P is taken out is easily converged at the elastic arm portion, so that the deformation distortion reaches another plate body region. Suppression and reliable positioning.

When taking out the package P, the pressing portion 23 is moved again by the movable bowl G in the direction of the arrow X1, the space between the positioning portion and the pressing portion is expanded, and the package P is taken out.

In the above embodiment, the base metal plate 3
Is composed of a single metal plate, but may be composed of a lower base metal plate on a flat plate and an upper base metal plate provided with a through recess at a mounting position of an electronic component to be mounted. .
Auxiliary positioning of the electronic component is performed in the penetrating concave portion of the upper base metal plate, which facilitates positioning. The thickness of the base metal plate and the positioning metal plate may be determined according to the height of the electronic component to be installed, and by changing the thickness of the upper metal plate, The thickness can be easily controlled.

A second embodiment of the present invention will be described with reference to the drawings. FIG. 3 is a plan view showing a second embodiment of the present invention. Although the basic configuration is similar to the above-described embodiment, in this embodiment, the positioning metal plate 5 is welded or fixed to the base metal plate 3 by screws. Outside the pressing portion 53, an operation regulation slope portion 55 extending from the positioning portion 51 is formed, and the corner portions 54a on both sides of the pressing portion 53 are configured to be gradually centered. The pressing direction is regulated so that the pressing portion 53 is centered by the operation regulating slope portion 55 and the pressing operation is correctly performed toward the positioning portion 51. Further, since the positioning metal plate is not formed integrally with the metal plate body, it can be replaced when it is partially damaged, deformed or aged. In addition, 54 is a slope portion.

Further, as shown in FIG.
2, a plurality of bent portions 52a may be provided to reduce the adverse effect of deformation of the elastic arm. Further, the above-mentioned thin processing may be used together.

[0021]

According to the first aspect, after extending in the direction away from both ends of the electronic component positioning portion for installing the electronic component, at least two elastic arms approaching each other, and connecting and pressing these elastic arms. Since the electronic component sometimes has a pressing portion in contact with a part of the electronic component, the pressing of the mounted electronic component by the pressing portion can be performed uniformly and stably. Further, since the elastic arm has no open end, there is almost no possibility that the elastic function is changed or lost due to deformation of the shape.

Further, the pressing portion is formed with two slopes formed by gradually decreasing the width toward the center portion, and the two corners of the electronic component are pressed and positioned and fixed by the slope. With this configuration, the electronic component is reliably positioned at a predetermined position even in a direction orthogonal to the pressing direction. The same positioning device can be applied even when the external sizes of the electronic components are slightly different.

Therefore, the positioning is performed accurately, for example, the mounting position of the electronic component element on the electronic component (package) does not shift, and a highly reliable assembly can be realized.
