Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Application of the Invention] The present invention relates to an assembly device for assembling objects to be assembled to a large number of assembly positions arranged in a row.

[Background of the invention]

For example, a connector formed by connecting connector blocks to both ends of a wire is used to electrically connect two printed wiring boards.

The connector is, for example, formed in a plurality of holes formed in a row at predetermined intervals in the connector block.

Insert the terminal hardware connected to the end of the wire in a separate process in advance (or insert the terminal hardware into the hole of the connector block in advance, insert the end of the wire into it, and then
It is formed by crimping the terminal hardware and the electric wire. (Hereinafter, a type in which a terminal metal fitting is inserted will be explained as an example.

) The connector, especially the connector block, corresponds to the miniaturization of electronic devices.
Miniaturization is progressing, such as forming six holes in a row for insertion of ~2m terminal metal fittings.

As described above, when the distance between the holes in the connector block into which the metal terminals are inserted becomes smaller, there is a limit to the miniaturization of the handling means for handling the metal terminals when attempting to automate the insertion of the metal terminals.

It becomes difficult to insert multiple pieces at the same time. For this purpose, the connector block is held by a holding means that is index movable in the direction in which the holes are arranged, and the terminal hardware is connected to one end of the wire.

The terminals are supported by insertion means that is movable in the axial direction, and are inserted into the holes of the connector block one by one. At this time, the terminal hardware is required to be completely inserted into the hole of the connector block, but if the terminal hardware is held by the insertion means, the terminal hardware cannot be completely inserted into the connector block. I can't. Further, when the electric wire connected to the terminal metal object is held by the insertion means, the position of the tip of the terminal metal object is not determined due to the effect of deformation of the electric wire, and the success rate of insertion decreases. For this reason.

This method has drawbacks such as a longer time for inserting the terminal hardware into the connector block and a lack of reliability in one operation.

Also, out of multiple holes in the connector block.

When making a connector without inserting a terminal metal object, the connector block must be moved by skipping that hole position.

[Purpose of the invention]

SUMMARY OF THE INVENTION An object of the present invention is to provide an assembly device which eliminates the above-mentioned drawbacks of the prior art and allows a plurality of terminal hardware to be inserted simultaneously and reliably into predetermined holes of a connector block.

[Summary of the invention]

The present invention achieves the above object.

a base movable in parallel to a plane orthogonal to the direction in which the holes of the connector block are arranged, and at least one or more pieces supported on the base so as to be movable in the direction in which the holes are arranged, each of which is arranged perpendicularly to the direction in which the holes are arranged; A pair of assembly units each having a plurality of clamp units each having at least one pair of holding means that can be individually opened and closed are arranged so as to face each other across the connector block, and are inserted into the hole of the connector block. Divide the terminal hardware that should be used into two sets alternately in the direction of arrangement.
Each set is held by the holding unit of the pair of bases.
By simultaneously inserting each set of terminal hardware into the connector block, the required number of terminal hardware can be assembled to the connector block in two insertion operations.

No unreasonable force is applied to e or V bars 26 (L to 26C).

In this way, the required number of terminal hardware can be inserted in two insertion operations.

In addition, the levers 15α+ 26a, i5C, 26c of the clamp units A, C in the above disaster example are based on the sizes of the clamp units A, B, C and the terminal hardware 74 (Z).
Depending on the relationship with the insertion interval of ~74f, it can be bent into a dogleg shape, as shown in FIG. 6, for example.

In addition, as shown in FIGS. 7(a) and 7(b), the lever 15

The relative positional relationship of B, C, and terminal hardware 74α, 74C to 74f is as shown in FIG. In other words.

Clamp unit A on the assembly unit 70A side is not used and operates idly. What is the insertion process?

Since this step is almost the same as the step shown in FIG. 5, only the differences will be explained.

First, when moving from (/1) in FIG. 5, the cylinder 60 of the assembly unit 70B operates and the stopper 64
protrudes between clamp units A and H. Then,
As shown in FIG. 9(a), the distance between the clamp units A and B is widened by 640 minutes of the stopper. In this - state, when the insertion process progresses as shown in Fig. 5, the terminal hardware 74 held on the 1 assembly unit 70B side
α, 74d, and 74f are holes 71α* 71d of the connector block 71, respectively.

71J'.

Next, the insertion process shown in (g) to (s) in Figure 5 proceeds.
When the insertion is completed in the same manner as in FIG. 5 (j), the state will be as shown in FIG. 9 (b). That is, the terminal hardware 74c and 74g held on the side of the first assembly unit 70A are inserted into the holes 71C and 74t of the connector block 71, respectively.
The terminal hardware 74A is not inserted into the terminal.

In this way, by using 64 stoppers, at least one of the holes 71a to 71f of the connector block 71 is
You can leave any number of positions vacant.

〔Effect of the invention〕

As described above, according to the present invention, the terminal metal objects to be inserted into the connector block are divided into two sets alternately according to their arrangement, and the required number of terminal metal objects are inserted into the connector block by two insertion operations. Therefore, even terminal metal objects with a small insertion pitch can be inserted efficiently.
Work efficiency can be greatly improved. Also.

Processes from parts processing to assembly can be effectively linked. Furthermore, the insertion position of the terminal metal object can be changed arbitrarily, which has an extremely large practical effect.
