Description

DETAILED DESCRIPTION OF THE INVENTION Field of Industrial Application The present invention relates to a pallet device that enables automatic machine assembly of products. The present invention relates to a two-layer parent-child pallet device that can accommodate the following.

Conventional structure and its problems Traditionally, in the manufacturing process of calculators, calculators were produced in a mixed manner, and even when considering automatic assembly of calculators,
There were so many different models that it was difficult for even a child to keep up with changing pallet setups, and since common pallet equipment was not available, pallets were hindering the automation of assembly. In addition, the model discrimination is also done manually, and there is a lot of work loss when the person selects each time, making it unsuitable for continuous automatic childbirth.

Purpose of the Invention The present invention solves the above-mentioned conventional drawbacks, and is a pallet device in which a common parent pallet is provided and child pallets are exchanged depending on the model.
At one end of the line, child pallets are stored in a stocker for each model, and can be automatically replaced depending on the model, and the main pallet is always the same board, making it compatible with many models. This provides a possible two-layer parent-child pallet device.

Structure of the Invention The present invention includes a two-layer pallet in the form of a plate, and the upper child pallet regulates the lower surface and outer peripheral edge of a substantially thin plate-shaped object placed on the main body of the child pallet. It is provided with a holding part, has a positionable guide hole that allows the attachment and detachment of the child pallet, and is provided with a through hole for identifying the model that extends from the child pallet to the parent pallet, On the other hand, the parent pallet has a memory pin for model switching, has a notch in the parent pallet body to enable positioning of the parent pallet, and is also equipped with a position adjustment pin when combined with a child pallet. As a result, it is possible to realize an optimal pallet device that enables automation in the assembly process of substantially thin plate-shaped parts such as calculators.

DESCRIPTION OF EMBODIMENTS An embodiment of the present invention will be described below with reference to FIGS. 1 to 4.

In the figure, 1 is the calculator main body, 2 is the parent palette, 3 is the memory pin, 4 is the child palette, 5 is the positioning pin installed on the parent palette 2, 6 is the guide hole on the child palette 4, 7 is a notch in the main body of the parent pallet 2, and 8 is a through hole provided on the child pallet 4 for model identification. Reference numeral 9 denotes a through hole for model identification, which is partially provided on the parent pallet 2 through the child pallet 4.

The operation of the pallet device constructed as described above will be explained below.

At the start of assembly of the calculator body 1, when a switching signal is given to the memory pin 3 on the parent pallet 2, the signal is automatically read from there and transferred to the child pallet 4 of the line.
The child pallet 4 is carried out from the stocker for
As shown in the figure, position adjustment pin 5 on parent pallet 2
The pallets are loaded through the guide holes 6 of the secondary pallets 4. Next, the calculator body 1 is placed on the child pallet 4 by a robot (not shown). The parent pallet 2 is also the substrate to be transported, and the parent pallet 2
Self-regulation is performed using the notch 7.
The model of the calculator 1 can be determined by having a plurality of holes 8 made in the stacked child pallets 4 and detecting the holes with a reflective phototube. When changing the model, a signal is similarly applied to the memory pin 3 on the parent pallet 2, and another child pallet 4 is taken out from the stocker and replaced, allowing the pallets to be sequentially changed on the automated line.

As described above, according to this embodiment, the child palette 4
Even if it is manufactured for multiple models, the parent pallet can be used in the same shape, and it is possible to automatically take out and load the pallet, as well as pallet transport, position adjustment, memory operation, and model identification. It has added value and can provide an optimal pallet device for use in assembling parts such as ultra-thin plates for calculators and the like.

Effects of the Invention As described above, the pallet device of the present invention has a plate-shaped two-layer pallet, and the child pallet that holds the object to be attached is manufactured according to the model, and the parent pallet that serves as the substrate is common. You can deal with this. Moreover, since the child pallets are loaded through the positioning pins of the parent pallet, there is no fear of misalignment, and manufacturing is possible at low cost and easily. In addition, the parent and child pallets have through-holes for model identification, making it possible to automatically distinguish between multiple patterns based on combinations of the presence and absence of holes.The pallet has a simple structure that can accommodate multiple models and is suitable for automation. It is ideal as a device.
