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 board.

[Conventional technology]

2. Description of the Related Art Conventionally, a machine called a terminal fitting transfer device has been used to efficiently assemble terminal fittings to a socket board. This consists of a flat transfer plate having a plurality of insertion holes with a pitch that is an integral multiple of the pitch of the assembly hole into which the terminal fitting is inserted and assembled on the socket board, and a bottomed cylinder that houses the transfer plate. It consists of a shaped box, a tilting mechanism that repeatedly tilts the box vertically and backwards, and a lateral vibration mechanism that swings the box horizontally.

In this conventional technology, when a large number of terminal fittings are placed in a box housing a transfer plate, the terminal fittings roll or slide on the transfer plate which is tilted and vibrates in the left and right directions due to the tilting mechanism and the lateral vibration mechanism. While falling, the terminals are fitted into the fitting holes formed on the transfer plate one after another with the terminals 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, for example, if the terminal fitting was not inserted into the insertion hole with the initial downward slope, it will be converted to the backward downward slope. It gets stuck while rolling backwards on the slope.

[Problem to be solved by the invention]

However, even in 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 with only the tilting mechanism (tilting mechanism) and the lateral vibration (lateral vibration mechanism), and therefore will not move inside the insertion hole. It's about becoming something you don't fit 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, the upper surface is formed with a pitch that is an integral multiple of the pitch between the mounting holes 9 formed on the socket board 7 into which the terminal fittings 8 are inserted and assembled, and the terminal fittings 8
A transfer plate 1 having a plurality of insertion holes 6 facing in the same direction, a box body 2 in which the transfer plate 1 is stored with its upper surface facing upward, and a box body 2 that can be folded forward and downward. In a transfer device comprising a tilting mechanism 3 that alternately and repeatedly tilts slowly, and a lateral vibration mechanism 4 that vibrates the box 2 in the left-right direction,
A vertical vibration mechanism 5 is provided to violently vibrate the box body 2 in the vertical direction.

[Effect]

When many terminal fittings 8 are placed in the box 2 housing the transfer plate 1 of the device of the present invention, the terminal fittings 8 roll on the upper surface of the transfer plate 1 which is tilted forward or backward by the tilting mechanism 3. Alternatively, as they slide down, they fit one after another into the insertion holes 6 formed on the upper surface of the transfer plate 1, which is vibrated from side to side by the lateral vibration mechanism 4.

In the device of the present invention, in addition to the above-mentioned horizontal vibration mechanism 4, the vertical vibration mechanism 5 is provided, so that the terminal metal fitting 8 is extremely lightweight, and even if the terminal metal fitting 8 is very humid, such as during the rainy season, the terminal metal fitting 8 Even in the case where the terminal fitting 8 is attached to the transfer plate 1, the terminal fitting 8 is detached from the transfer plate 1 due to the severe vibration in the vertical direction in addition to the horizontal vibration. Then, as it rolls and slides on the slope, it is inserted into the insertion hole 6 of the transfer plate 1, 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. Arranged boxes and containers 24
(See Figure 7). As a result, the terminal side of the terminal fitting 8 is connected to the socket board 7 assembly hole 9.
fit inside. Next, the box body 2 is removed, and the terminal fitting 8 fitted into the assembling hole 9 is press-fitted into the assembling hole 9 by pressing the socket side thereof. This allows multiple
It manufactures IC sockets.

〔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, and the vibration is 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. This is what I did.

The transverse vibration mechanism 4 has a vertical axis 1 transmitted from an electric motor.
0 rotational motion is converted into reciprocating motion via the eccentric shaft 11 and transmitted to the horizontal shaft 12, and the box body 2
I'm telling you. The 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, but may be constructed of any generally used mechanism that performs reciprocating motion.

A tilting mechanism 3 for tilting the box body 2 includes a bearing 1 fixed to the box body 2, and a crankshaft 17 that moves up and down.
This has been achieved by so-called general means connected to 8.

FIG. 2 shows another embodiment. In this embodiment, the longitudinal vibration mechanism 5 is an iron core (magnet).
15 and an electromagnetic coil 16 surrounding the iron core 15, and these integral parts are attached to the box body 2. When a current is passed through this electromagnetic coil 16, the iron core 1
5 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 a longitudinal vibration mechanism 5 consisting of an iron core (magnet) 15 and an electromagnetic coil 16 is attached to a support base 19 that supports a guide shaft 9. In this case, not only the box body 2 but also other members are subjected to longitudinal vibration.

FIG. 4 shows yet another embodiment. This uses air pressure, and has a piston device attached to the 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 space below the cylinder 21, so the piston 20
When the nozzle 22 moves upward, air is supplied to the upper space of the cylinder 21, so the piston 20 moves downward.

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

Note that the terminal fitting 8 and the socket board 7 referred to in the present invention are not limited to the shapes shown in the figures in the above embodiments; for example, the terminal fitting 8 may have a shape as shown in FIG. This also includes the following.

〔Effect of the invention〕

As described above, the present invention applies severe vertical vibrations to the transfer plate 1, so even if the terminal fitting 8 is lightweight and easily adheres to the transfer plate 1 due to moisture, the vertical vibrations can be applied to the transfer plate 1. As a result, the attachment to the transfer plate 1 is removed, and the transfer plate 1 is easily inserted into the insertion hole 6. This increases the efficiency and reliability of work and exhibits excellent effects such as increasing productivity.
