Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a parts assembling apparatus used for assembling parts such as push switches having an O-ring.

[0002]

2. Description of the Related Art Conventionally, when assembling a push switch, the O-ring has been incorporated into the switch body manually. The O-ring is generally installed by inserting it into a small-diameter portion inside the flange portion that is larger than the inner diameter of the O-ring. Such work is troublesome because the O-ring is an elastic body such as rubber and the portion where the O-ring is incorporated is tight. Therefore, O
Assembly work of the ring has a great influence on the cost of the product, and it has been expected that the work efficiency is improved. One way to improve work efficiency is to use a jig for assembling even in manual work. For example, there is a method in which a large number of O-rings are fitted into a jig having a trumpet shape, and the O-ring is transferred from the jig to the switch body side while the switch body is applied to the tip side of the jig.

[0003]

The manual work using such a jig has the following problems. a. Even if you use a jig, the assembly work itself is a manual work,
It is necessary to attach an O-ring to the jig as a preparatory work for assembly, and work efficiency is poor. b. Since the O-ring has flexibility, it is difficult to spread the O-ring and transfer it, and the work efficiency is still poor. c. The O-ring transferred on the jig is twisted, and the O-ring is mounted on the component side while being twisted. If the twist generated in the O-ring is significant, the O-ring itself may be damaged and there is a risk of reducing the reliability of the parts.

Therefore, an object of the present invention is to provide a parts assembling apparatus which improves the efficiency of the parts assembling work and improves the reliability.

[0005]

The component assembling apparatus of the present invention, as illustrated in FIG. 1, is a pin (10) which is inserted into an O-ring (7) to be incorporated into a component and whose inner diameter is expanded.
And a supply nozzle (O-ring supply nozzle 21) having a continuous diameter in the tapered portion (106) of the pin, the pin is attached to and detached from the supply nozzle, and the O on the supply nozzle side received from the pin is provided. An O-ring supply nozzle mechanism that transfers the ring to the component (push button switch 6) side, and an O-ring expansion mechanism (3) that pushes up the O-ring on the pin from the tapered portion to the supply nozzle side.
And an O-ring dropping mechanism (23) for dropping the O-ring on the supply nozzle into the component.

[0006] The pin may be of any form as long as it holds the O-ring and expands it.
In addition to the insertion portion having a diameter slightly larger than the inner diameter of the ring, the insertion portion is also provided with a tapered portion continuously expanding in diameter.

The pin is attached to and detached from the supply nozzle by an O-ring supply nozzle mechanism. A pin stand (32) is provided as an auxiliary means for attachment / detachment.

Further, in order to automate the processing of the parts to be mounted by the O-ring and the mounted parts, an auxiliary means is required, and the present invention provides a parts pallet for aligning the parts and the parts pallet. And a positioning mechanism for positioning at a predetermined position.

In order to realize the automated processing of mounting the O-ring on the component, it is necessary to optimize the supply of the O-ring. Therefore, the present invention includes an O-ring pallet that aligns the O-rings and a positioning mechanism that positions the O-ring pallet at a predetermined position.

[0010]

After the supply nozzle mechanism holds the pin in the supply nozzle, the pin is inserted into the O-ring to hold the O-ring on the pin. The O-ring is pushed up on the pin by the O-ring expanding mechanism to be expanded and transferred to the supply nozzle side. In this state, the pin is removed from the supply nord mechanism, and the O-ring is transferred to the component side together with the supply nozzle. Then, the O-ring is dropped onto the component side by the O-ring dropping mechanism and attached to the component.

The pin is a jig for holding the O-ring and expanding the O-ring. The pin has an insertion portion having a diameter slightly larger than the inner diameter of the O-ring, and the diameter is continuously expanded to the insertion portion. It is provided with a taper portion. With such a pin, the O-ring inserted in the insertion part
By pushing up the taper portion, the inner diameter can be expanded.

The pins are placed on the pin rest. Pin is O
This is a jig for expanding the ring, and after holding and expanding the O-ring, it is not necessary until the next mounting, and it is stored in a pin mounting table at a predetermined position and made to stand by.

A parts pallet is installed as a means for aligning the parts, and the positioning is performed by a positioning mechanism. This contributes to the automation of the processing of the component mounted on the O-ring and the mounted component, and the processing accuracy is improved.

An O-ring pallet is installed as a means for aligning the O-rings, and its positioning is processed by a positioning mechanism. The automatic processing of mounting the O-ring on the part is realized, and the supply of the O-ring is optimized.
