Abstract

PURPOSE:To insert three lead wires into the hole of a carrier tape without interruption by installing three conical holes whose inlets are larger than the pitch of the lead wires and whose outlets are smaller than a pushing-in hole, dividing a guide into two segments at arbitrary positions of the holes, and making the guide capable of opening and shutting. CONSTITUTION:Three lead wires of a semiconductor device 1 are inserted into a guide 3 in which three conical hole parts are formed. The inlet of the hole is larger than the pitch of the lead wires, and the outlet is smaller than the insertion hole 4 of a carrier tape 2. The guide 3 is made capable of opening and shutting by dividing the guide into two segments at the conical hole parts. After the three lead wires of the semiconductor device 1 are inserted into the three conical hole parts of the guide 3, and the lead wires are fitted in the insertion hole 4 of the carrier tape 2, the guide 3 is divided and released. Thereby the three lead wires can be inserted into the insertion hole of the carrier tape without interruption.

Description

DETAILED DESCRIPTION OF THE INVENTION Field of Industrial Application The present invention relates to a guide for inserting lead wires into a jig or the like of a semiconductor device having three lead wires such as a semiconductor laser, that is, a lead wire current supply means. This invention relates to a regulating device.

BACKGROUND OF THE INVENTION Conventional semiconductor devices, such as semiconductor lasers and other semiconductor devices with three lead wires, require manual insertion of the semiconductor device into the carrier tape during the assembly process onto the carrier tape. It was an insertion. Therefore, there was no particular need for an insertion lead regulating device or the like.

Problems to be Solved by the Invention When automatically directly inserting the semiconductor device into the carrier tape, there is a problem in that if the leads are bent, the lead tips cannot be inserted into the holes in the carrier tape.

In order to solve this problem, the present invention provides a method for regulating and inserting a lead using a lead wire regulating device having a conical hole.

Means for Solving the Problems The present invention provides a guide for inserting three lead wires,
The guide is provided with three conical holes whose width is larger than the pitch of the lead wires and whose exit is smaller than the insertion hole of the board, and the guide is divided into two by the conical holes and can be opened. It is.

According to the present invention, after inserting the three lead wires of the semiconductor device into the three conical holes of the guide, at the stage when the three lead wires have entered the insertion holes of the board, the guide is inserted. By dividing and opening, the three lead wires of the semiconductor device can be inserted into the insertion holes of the substrate without any trouble.

Embodiment FIGS. 1(a), (b), and (C) show the configuration of an embodiment of the present invention, and the process of its use (a), (b), and (C").
), in which (a) shows the semiconductor device before insertion, (b) shows it during insertion, and (C) shows three conical holes opened and the lead wire inserted into the insertion hole of the board. Indicates fully inserted state.

In FIG. 1, 1 is a semiconductor device, 2 is a carrier tape as a substrate, and 3 is a lead wire regulating device.

The three lead wires of the semiconductor device 1 are connected to a lead wire regulating device 3.
The end of the lead wire is inserted into the carrier tape hole 4.

Thereafter, as shown in FIG. 1(C), the conical hole is opened and the lead wire is completely inserted. The lead wire is squeezed by the conical hole during insertion, but returns to its original state due to springback after insertion.

FIGS. 2(a) and 2(b) are a plan view and a sectional view for explaining the operation of the lead wire regulating device of the present invention.

When inserting the semiconductor device 1 into the carrier tape 2, by inserting the lead wire regulating device 3 having a conical hole in the front, even if the lead wires of the semiconductor device are slightly bent outward or inward, When the lead wire tip enters the opening of the lead wire regulating device, it slides on the slope of the conical hole, passes through the exit, and is inserted into the carrier tape hole 4.

Of course, the width of the lead wire regulating device is wider than the lead pitch of the semiconductor device (and it goes without saying that the exit is smaller than the insertion hole 4 of the carrier tape).

The three conical holes are divided into two at arbitrary positions, and after the lead tip enters the carrier tape hole, it is sufficient to open both sides.

As described in detail, according to the present invention, lead insertion of semiconductor devices, which had previously been done manually, can now be performed using an automatic machine, thereby significantly improving productivity.

Further, even if the lead is slightly deformed, the lead wire regulating device can facilitate insertion.
