Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to an electronic component push-up pin mechanism for pushing up an electronic component that does not have a lead wire and is housed in a cartridge.

Recently, electronic components have become smaller, and chip capacitors (also called multilayer capacitors) are becoming more and more compact.

) and other small electronic components that do not have a Riet wire are becoming widely used.

This type of electronic component has extremely small external dimensions; for example, a chip capacitor is 3.2 rrrm (horizontal) Xl, 6
Since it is about m (length) Xo, 6 +++ m (thickness), =
It is extremely inefficient to manually attach each individual piece to a printed circuit board like other electronic parts.

For this reason, as shown in FIG. 1, electronic components 4 are stored in a stacked state in a cartridge 3 that is supported upright between a magazine upper plate 1 and a magazine lower plate 2, and these electronic components 4 are supported. The present applicant has previously proposed a mechanism in which the electronic components 4 are fed one by one to a transfer suction plate by pushing up the stopper 5 with an electronic component push-up pin 6.

In this case, the electronic component push-up pin 6 is easily bent due to the load during pushing up, and the mounting position must be changed in response to changes in the position of the cartridge 3, so the structure allows for easy removal and replacement of the push-up pin 6. It is desirable that

In view of the above points, the present invention aims to provide an electronic component push-up pin mechanism in which the electronic component push-up pin can be easily removed and replaced.

Embodiments of the electronic component push-up pin mechanism according to the present invention will be described below with reference to the drawings.

In FIGS. 2 and 3, the base 10 of the device main body includes:
A fixed guide plate mount 11 is fixed, and a movable guide plate mount 12 is provided so as to be movable up and down with respect to the base 10.

A movable guide plate 13 for fixing the electronic component push-up pin 6 is fixedly supported on the movable guide plate mount 12 .

A screw hole 1 is provided at the push-up pin mounting position of the movable guide plate 13.
4 is formed, and a removal screw pin 15 is screwed into the screw hole 14.

A through hole 16 is formed in the center of the removal screw pin 15, and a driver groove 1γ is formed in the lower end surface, and the removal screw pin 15 is screwed into the driver groove 1γ.

On the other hand, in the middle of the push-up pin 6, there is a screw pin 1 for removal.
With a retaining ring 18 having an outer diameter smaller than 5 fixed and a compression spring 19 provided so as to come into contact with this retaining ring 18, the push-up pin 6 is inserted into the through hole 16 of the removal screw pin 15, and the retaining ring 20, it is attached to the removal screw pin 15 so as to be slidable downward.

The push-up pin 6 is guided vertically by a fixed guide plate 21 fixed to the fixed guide plate mount 11.
It moves up and down in response to the elevation of the movable guide plate mount 12.

Further, the tip of the push-up pin 6 comes into contact with a stopper inside the cartridge 3 supported by the magazine 31 when the magazine 31 is placed on the magazine mounting table 30.

In the above configuration, the movable guide plate mount 12 normally moves up by the thickness of the electronic component in one operation, and the tip of the push-up pin 6 also rises accordingly, pushing up the plug in the cartridge 3.

In this case, since the push-up pin 6 is not directly fixed to the movable guide plate 13 and is only urged upward by the compression spring 19, the push-up pin 6, the stopper, and the electronic components are protected from the impact that is applied when pushing up. Can be absorbed.

In addition, if the push-up pin 6 is bent due to some kind of load, the push-up pin 6 must be replaced, but in this case, the retaining ring 20 is removed and the removal screw pin 15 is inserted into its driver groove 1γ. After removing it with a screwdriver or the like, it can be easily removed by pulling out the push-up pin 6 downward.

In the above embodiment, the screw pin 15 for removal is provided with a driver groove 1γ, but a cross groove, a square recess, etc. may be formed so that attachment and removal can be performed using a tool or jig other than a driver.

As explained above, according to the electronic component push-up pin mechanism of the present invention, the electronic component push-up pin is inserted through and attached to the removal screw pin having a larger outer diameter than the retaining ring. Easy to remove and replace.
