JPS63120041A - Pallet with automatic assembling sticky elastic body - Google Patents

Abstract

PURPOSE:To make a set part positively holdable to a pallet even if the pallet receives a mechanical vibration and an electric shock, by attaching a sticky elastic body to an inner bottom part of the pallet. CONSTITUTION:A pallet 1 is one that is made of plastic and pressed in with each metal guide 5 and a sticky elastic body 3 is attached to its inner bottom part 2, while a position of each metal guide 5a is situated in a lower state than each sticky elastic body 3a. A part 4 is set to the pallet 1 vertically with each guide 5 of the pallet 1 and vertical load W of less than C is added to the sticky elastic body 3 via the part 4 whereby they can be stuck fast with proper adhesion of the elastic body 3 and the part 4. Therefore, the part 4 set to the pallet 1 is attachable without entailing any falling, scattering and deformation, breakage.

Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to a pallet used in automatic assembly of small and lightweight parts such as watches, cameras, and various mechatronic products.

[Summary of the invention]

With conventional automatic assembly pallets, the parts to be set engage freely with the guides of the pallet and are stacked, or the parts to be set engage with the guides of the pallet and the external parts are press-fitted into the pallet. Two mounting structures are used that are stacked.

In the former case, parts fall off and scatter from the pallet due to vibrations and shocks received when the pallet is transported on a line such as a chain or belt. The latter had the problem of deformation and breakage when the parts were press-fitted into the pallet, but with the present invention, the set parts are held freely in the guide of the pallet, and the parts are stacked and worn with appropriate adhesion. By being mounted on a pallet, it is resistant to vibration and shock and prevents damage to parts.
This is a pallet with an adhesive elastic material that makes it possible to advantageously improve the direct line rate of automatic assembly and the yield of parts.

[Conventional technology]

In conventional automatic assembly pallets, the parts to be set freely engage the guides of the pallet and are stacked, or the parts to be placed engage the guides of the pallet and the external parts are press-fitted into the pallet. A pallet structure is known for two installations in which they are stacked one on top of the other.

[Problem that the invention seeks to solve]

Conventional automatic assembly pallets have problems with parts deforming, breaking, falling off, and scattering, which increases assembly costs. Therefore, this invention uses an adhesive elastic material on the inner bottom of a pallet for automatic assembly, so that the parts to be set can be stacked and attached to the pallet with appropriate adhesiveness while being free to guide the pallet. This is a pallet with adhesive elastic material that enables an inexpensive automatic assembly pallet with good properties and a high yield of parts.

[Means for solving problems]

In order to solve the above-mentioned problems, the present invention has been developed as shown in FIG. The parts 4 are attached to the adhesive elastic body 3 with appropriate adhesive force, and form a means for stacking and attaching the parts 4 to the pallet 1.
It was possible to install the parts 4 set in the parts 4 without falling off, scattering, deforming, or damaging them.

[Effect]

The pallet with an adhesive elastic body configured as described above has a first
By adhering the adhesive elastic body 3 and the component 4 shown in the figure, the second
As shown in the figure, the parts 6 are press-fitted by freely engaging the guides 5 of a conventional pallet (parts 4 that are stacked while freely engaging the guides 5 of aluminum or stacked pallets). It is possible to obtain the same or more reliable holding force for the parts 4 than for the stacked parts 4.

〔Example〕

Embodiments of the present invention will be described below based on the drawings. In FIG. 3, the pallet 1 of the present invention is made of plastic with a metal guide 5 press-fitted and an adhesive elastic body 3 attached to the inner bottom 2 of the pallet 1, and the position of the metal guide 5a is higher than the adhesive elastic body 3a. The structure is in a low position. Place the component 4 on the pallet 1 perpendicularly to the guide 5 of the pallet 1, and apply a vertical load W of C or less to the adhesive elastic body 3 via the component 4.
Can be attached with moderate adhesive strength.

In the above embodiment, even if the pallet 1 being transferred on a line such as a chain or belt during automatic assembly is subjected to mechanical vibration or electrical shock, the parts 4 being placed are securely held on the pallet 1. It made it possible to exist.

〔Effect of the invention〕

As explained above, this invention has a simple structure in which an adhesive elastic body is attached to the inner bottom of a conventional automatic assembly pallet, and is inexpensive, easy to assemble, has a high yield of parts, and has the effect of reducing assembly costs. There is.
