Description

DETAILED DESCRIPTION OF THE INVENTION Field of the Invention The present invention relates to a component clamping device in, for example, a device for automatically inserting electronic components (hereinafter referred to as components) into a printed circuit board.

Conventional parts holding devices are shown in Figures 4, 5, and 6.
As shown in Fig. 7.

The first example shown in FIGS. 4 and 5 is an insertion guide 9 that can be opened and closed and is made up of two movable members 7 and 8.
The two lead wires 1a of the component 1 are guided through the two tapered guide holes 10 formed by the two lead wires 1a and inserted into the printed circuit board 6. That is, the two lead wires 1a of the component 1 fed and transferred to the insertion guide 9 are held between them, and the component 1 is brought close to a predetermined position on the printed circuit board 6, and then the pusher 11 is lowered to insert the component 1 into the hole of the printed circuit board 6. When the two lead wires 1a led out below the printed circuit board 6 are cut and clinched by an insertion and clinch device (not shown), the movable members 7 and 8 of the insertion guide 9 simultaneously rise while opening.

Further, FIGS. 6 and 7 are a second example. Chuck the part 1 with the gripping claw 12 and insert it into the insertion guide 13.
The lead wire 1a is guided through the tapered guide groove 14 formed by the hole 1 of the printed circuit board 6.
5.

However, in the first example, although the insertion pitch becomes slightly smaller when inserting parts sequentially from one side, a large insertion pitch is required between the inserted parts, and furthermore, it is impossible to insert parts with three legs.

Further, in the second example, the insertion pitch is large due to the thickness of the gripping claws 12, and insertion of a three-legged component is also impossible as in the first example.

There is no clamping device that has the above-mentioned drawbacks and satisfies the conditions arising from the automatic insertion of all components and the order of insertion that are currently commonly used.

OBJECTS OF THE INVENTION The object of the present invention is to eliminate the above-mentioned drawbacks, and to enable a component holding device to insert a component with a small pitch between the inserted components, and also to insert a three-legged component.

The first and second slide shafts 16 and 17 rotate in the same manner with respect to the center of the component 1, and can be slid up and down separately.

The first slide shaft 16 is provided with a cam surface 20 for sliding a roller 31 provided on a swing block 29 in order to cause the pusher 18 and the clamping portion 19 to escape in the direction in which the lead wires 1a are lined up.

The second slide shaft 17 includes a stopper block 21 for setting the reference position of the clamping part 19, a spring 22 fixed to the upper part of a piston 25 that assists the clamping claw _19-1 of the clamping part 19 in escape, and A fulcrum pin 23 is attached that serves as the center point of the swing of the swing block 29.
