CONSTITUTION:When an electronic component 2 is disposed on a positioning base 1 in a case where X-direction and Y-direction pawls 6, 8 are not completely crossed perpendicularly, a Y-direction movable base 7 is moved toward the base 1, the pawl 8 which is not oscillated is engaged with a Y-direction lead terminal 3 of the component 2, and the component 2 is positioned in a Y direction. Then, an X-direction movable base 4 is moved toward the base 4 in synchronization with the movement of the base 7, and the pawl 6 is engaged with an X-direction lead terminal 3 of the component 2. In this case, the pawl 6 is oscillated to follow the engaging movement of the pawl 8 to position the component 2 in an X direction. Even if the X-direction and the Y-directions are not completely crossed perpendicularly and a gap is generated between the pawl 6 and the terminal 3 of the component 2, the pawl 6 is oscillated to bury the gap to properly position it.

(Problem to be Solved by the Invention) The conventional electronic component positioning device is configured as described above, and in order to position the electronic component (2) with high precision,
The six motion directions of direction types (6) and (8), in other words, the X direction and the Y direction must be surely perpendicular to each other, and it takes a lot of time to make adjustments to make them perpendicular.

The present invention has been made in view of the above points, and an object of the present invention is to provide an electronic component positioning device that has a simple configuration and can significantly shorten adjustment time.

(Means for Solving the Problems) In order to achieve the above-mentioned object, the present invention provides an electronic component equipped with a large number of lead terminals arranged on a positioning stand;
A plurality of movable bases are provided on both sides of the positioning base and a plurality of movable bases that sandwich the positioning base and are arranged to be reciprocally movable in orthogonal directions perpendicular to the both sides, and the positioning claws of the movable base are connected to the electronic components on the positioning base. In devices that are positioned by engaging with lead terminals, a support is attached to a movable base in one of the above-mentioned both directions and orthogonal directions, and a positioning claw is reciprocated at the tip of the support that is oriented toward the positioning base. It is characterized by being pivoted so that it can swing freely in the direction of movement.

[Effect]

According to the present invention, a support is attached to a movable stage in either the bilateral direction or the orthogonal direction, and the positioning claw is swung in the reciprocating direction at the tip of the support that is directed toward the positioning base. Since it is rotatably supported on the shaft, the swingable positioning claw can absorb errors that occur during adjustment, and the X-
The adjustment time for orthogonality in the Y direction can be significantly shortened.

(Example) Hereinafter, the present invention will be described in detail based on an example shown in FIG. 1. In the figure, (S) is a rotating shaft rotatably inserted into the hole at the tip of the elastic body (5) This rotating shaft (9) is equipped with a flat X-direction type (6) that operates in the same manner as the conventional example.
), and this X-direction type (6) is attached to the rotation axis (9
) in the Y direction, in other words, it swings in the X direction in a reciprocating manner. Therefore, (lO) is the spring placed between this X-direction mold (6) and the tip of the elastic body,
This spring (10) functions to hold the X-direction type (6) in the state shown in FIG. is the same as

Therefore, when the moving directions of the X-direction wind (6) and the Y-direction wind (8) are not completely orthogonal, the electronic component (2)
is placed on the positioning table (1) by the parts supply device, the moving table (7) in the Y direction moves to the positioning table (1).

That is, the X-direction lead terminal (3) of the electronic component (2) is attached to the long side engagement surface of the X-direction wind (6).
If all of the lead terminals (3) in the X direction do not engage, the X direction wind (6) swings to engage the engagement surface with all the lead terminals (3) in the X direction, and if they are arranged completely orthogonally. Positioning is done in the same way.

However, according to the present invention, when the X-Y directions are not completely orthogonal, the X-direction wind (6) and the electronic component (2)
Even if a gap may occur between the lead terminals (3) in the X direction, the X direction wind (6) swings to fill the gap and position it properly, so This makes it possible to significantly shorten the adjustment time.

Although the directional wind (6) is shown in a structure that can swing freely, Y
The directional wind (8) may be configured to be swingable. However, if the X-direction wind (6), (6) is configured to be swingable, the Y-direction wind (8), (81) can be changed to the Y-direction wind (8),
When configuring (8) to be swingable, use the X direction wind (6)
, (6) must be constructed so that they do not oscillate.
