Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to a terminal fitting transfer device for fitting terminal fittings together into a socket substrate.

[Conventional technology]

BACKGROUND ART Conventionally, a machine called a terminal fitting transfer device has been used to efficiently assemble terminal fittings onto a socket board. This is a socket board.

A flat transfer plate having a plurality of insertion holes formed at a pitch that is an integral multiple of the pitch of the assembly holes into which the terminal fittings are inserted and assembled, a bottomed cylindrical box housing the transfer plate, and the It consists of a tilting mechanism that repeatedly tilts the box body forward and backward and downward, and a lateral vibration mechanism that causes the box body to oscillate from side to side.

In this prior art, when a large number of terminal fittings are placed inside a box housing a transfer board, the terminal fittings become...

While rolling or sliding on a transfer plate that is tilted and vibrates in left and right directions by a tilting mechanism and a lateral vibration mechanism, the terminals are fitted one after another into the insertion holes formed on the transfer plate while facing in the same direction.

In addition, since the transfer plate is set to be tilted alternately in both front and rear directions by the tilting mechanism,9 for example, if the terminal fitting was not inserted into the insertion hole with the initial downward slope, it is converted to the backward downward slope. It gets stuck while rolling backwards on the slope.

[Problem to be solved by the invention]

However, even with such conventional technology.

There are problems to be solved. This is because if the terminal fitting is particularly lightweight and the humidity is high, the terminal fitting will stick to the transfer plate and will not move only with the tilting mechanism and the lateral vibrations caused by the lateral vibration mechanism, so that it will not fit into the insertion hole. The problem is that it becomes difficult to get into.

The present invention was devised in view of these problems, and provides a terminal fitting transfer device in which the terminal fitting is lightweight, and the terminal fitting can easily fit into the insertion hole without being affected by moisture even in a humid environment. The purpose is to provide.

[Means to solve the problem]

Therefore, a plurality of holes are formed on the upper surface at a pitch that is an integral multiple of the pitch between the mounting holes 9 formed on the socket board 7 and into which the terminal fittings 8 are fitted and assembled, and into which the terminal fittings 8 are fitted facing in the same direction. A transfer plate 1 having a fitting hole 6, a box body 2 in which the transfer plate 1 is stored with the top surface facing up, and a tilting mechanism 3 that slowly tilts the box body 2 alternately and repeatedly downward from the front and downward from the rear. and a horizontal vibration mechanism 4 that vibrates the box 2 in the left-right direction, and a longitudinal vibration mechanism 5 that vibrates the box 2 violently in the vertical direction.

[Effect]

When many terminal fittings 8 are placed in the box 2 housing the transfer plate l of the device of the present invention, the terminal fittings 8 roll or slide on the upper surface of the transfer plate l which is tilted forward or backward by the tilting mechanism 3. At the same time, the insertion hole 6 formed in the upper surface of the transfer plate 1 vibrates from side to side by the lateral vibration mechanism 4.
They fit inside one after another.

In the device of the present invention, in addition to the above-mentioned lateral vibration mechanism 4,
Since the vertical vibration mechanism 5 is provided, even if the terminal fitting 8 is extremely lightweight and there is high humidity such as during the rainy season, the terminal fitting 8 may stick to the transfer board l. ,
In addition to horizontal vibrations, intense vertical vibrations cause
The terminal fitting 8 is removed from the transfer plate 1. Then, as it rolls and slides on the slope, it is inserted into the insertion hole 6 of the transfer plate l, which is swung laterally to the left and right (see FIG. 5).

Incidentally, the transfer plate 1 (see FIG. 6) with the terminal fittings 8 fitted into all the fitting holes 6 is taken out from the box body 2, and a plurality of socket boards 7 corresponding to the number of the terminal fittings 8 are removed. The two are combined with the aligned boxes 24 (see FIG. 7). As a result, the terminal side of the terminal fitting 8 is fitted into the socket board 7 assembly tag 9. Next, the first box 2 is removed and the terminal fitting 8 fitted into the first assembling hole 9 is press-fitted into the assembling hole 9 by pressing the socket side thereof. In this way, a plurality of IC sockets can be manufactured at one time.

〔Example〕

An example is shown in FIG. The longitudinal vibration device in this embodiment is composed of a motor 13 and an unbalanced wheel attached to its rotating shaft, which is attached to the box body 2.

The motor 13 vibrates slightly due to the action of the unbalanced wheel 14.

The minute vibrations are transmitted to the box body 2 to cause the transfer plate 1 housed in the box body 2 to vibrate slightly in the vertical direction.

The transverse vibration mechanism 4 converts the rotational motion of the vertical shaft 10 transmitted from the electric motor into a reciprocating motion via the eccentric shaft 11, transmits it to the horizontal shaft 12, and transmits it to the nine-box body 2. Box body 2
is attached to the guide shaft 23 so as to be slidable in the left and right directions. Note that the lateral vibration mechanism 4 is not limited to the mechanism shown in this embodiment.

It is constructed from any commonly used reciprocating mechanism.

A tilting mechanism 3 for tilting the box 2 connects a crankshaft 17 that moves up and down to a bearing 18 fixed to the box 2.

This has been achieved by what is called a boat fishing method.

FIG. 2 shows another embodiment. In this embodiment, the longitudinal vibration mechanism 5 is composed of an iron core (magnet) 15 and an electromagnetic coil 16 surrounding the iron core 15, and these are integrally attached to the box body 2. When a current is passed through the electromagnetic coil 16, the iron core 15 and the electromagnetic coil 16 cause relative vertical vibration. When this vertical movement is transmitted to the box body 2, the transfer plate 1 vibrates vertically.

FIG. 3 shows another embodiment, in which the iron core (magnet) 15
and a longitudinal vibration mechanism 5 consisting of an electromagnetic coil 16.

It is attached to a support stand 19 that supports the guide shaft 9.

This is intended to cause longitudinal vibration not only in the two-box body 2 but also in other members.

FIG. 4 shows yet another embodiment.

This uses air pressure and has a piston device assembled into a single box body 2. The piston 20 within the cylinder 21 is moved up and down by air pressure, and vibrations generated by the up and down movement are transmitted to the box 2, thereby causing the transfer plate 1 to vibrate. Air is supplied into the cylinder 21 from a nozzle 22 that moves up and down continuously. When the nozzle 22 descends, air is supplied to the upper space of the cylinder 2I, so when the piston 20 moves upward and the 5 nozzle 22 ascends, air is supplied to the upper space of the cylinder 21. 20 is the one that is displaced downward.

In addition, mechanisms for applying vertical vibration to the box body 2 can be achieved by various commonly used mechanical and electrical means (for example, a mechanism that uses the elasticity of a leaf spring). etc. is one of them). The present invention is characterized in that vertical vibration is applied to the 1-box body 2, and the longitudinal vibration mechanism 5 as a means for applying @1 vibration includes all such commonly used means.

Note that the terminal fitting 8 and socket M plate 7 referred to in the present invention are as follows:
The present invention is not limited to the shape shown in the figures in the above-mentioned embodiments; for example, the terminal fitting 8 may have a shape as shown in FIG. 8.

〔Effect of the invention〕

In this way, the present invention applies severe vertical vibrations to the transfer plate 1, so that the transfer plate 1 is lightweight and moist.
Even if the terminal metal fitting 8 easily adheres to the transfer plate 1, its vertical vibration causes it to come loose from the transfer plate 1 and is easily inserted into the insertion hole 6. This increases the efficiency and reliability of one task, and has the excellent effect of increasing productivity.
