Abstract

PURPOSE:To enable a board held by a clamp to be easily turned around without detaching it from the clamp. CONSTITUTION:A clamp 20 and a stopper 30 are supported at a gate-shaped frame 12 supported on the board 11 of a base 10. The clamp 20 is screwed down to a block, 13 fastened to the frame 12, wherein the bent part 23a of one of pressing pieces 23 of a pinching member 21 is fastened to the block 13 by a machine screw, and the clamp 20 is set rotatable to such an extent, that it is capable of holding the pinched board at an optional position. Therefore, the clamp 20 is turned, whereby the pinched board can be easily reversed.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a substrate holder used for mounting electronic components on a substrate.

[0002]

2. Description of the Related Art As a substrate holder used when mounting electronic components on a substrate,
It is general that a clamp for clamping a substrate is fixed to a base. Therefore, for example, when an element such as a resistor is mounted on the substrate, first, the substrate is sandwiched and held by the clamp so that one surface side faces upward, and the lead wire of the element penetrates through the substrate. Next, it is necessary to once remove the board from the clamp, hold the board in the clamp so that the other surface side of the board faces upward, and solder lead wires to the board.

As described above, in the conventional substrate holder, when it is necessary to perform processing on both sides of the substrate, the substrate has to be clamped and removed many times, resulting in poor workability. There was a point.

SUMMARY OF THE INVENTION Therefore, an object of the present invention is to provide a substrate holder which can be easily inverted without removing the substrate once held in the clamp.

[0005]

In order to solve the above-mentioned problems, the present invention provides a clamp for holding a substrate, and a base for rotatably supporting the clamp so that the held substrate is reversed at the same position. And a holding means for holding the clamp at a position where the front surface and the back surface of the sandwiched substrate face upward, respectively.

Further, the base may be provided with a stopper for restricting the rotation angle of the clamp.

[0007]

In the substrate holder configured as described above, when the clamp is rotated while sandwiching the substrate, the holding means holds the substrate in a position in which the front surface or the back surface of the substrate faces upward. Further, in the case where the stopper is provided, the clamp does not rotate more than necessary.

[0008]

EXAMPLES Examples will be described below with reference to the drawings. As shown in FIG. 1, the substrate holder 1 of the present invention includes a base 10, a clamp 20, and a stopper 30.

As shown in FIG. 1, the base 10 includes a substrate 11 and a gate-shaped frame 1 supported on the substrate 11.
A block 13 for mounting the clamp 20 is fixed to the frame 12 at the upper side surface of the center thereof.

The clamp 20, as shown in FIG.
A pair of sandwiching members 21 having a pressing piece 23 at the rear end of the sandwiching piece 22, a support piece 24 formed in the middle of the pressing piece 23.
The holding member 21 is openably and closably connected by a shaft 25 passing through the portion, and the holding member 21 is biased in a closing direction by a coiled spring (not shown) passing through the shaft 25.

This clamp 20 has one holding member 21.
The tip of the pressing piece 23 is bent inward, and the bent portion 23 a is fixed to the block 13 with a screw 26. The screwed clamp 20 is not completely fixed to the block 13, but is rotatably attached to such an extent that it can be held at an arbitrary position by an appropriate tightening force of the screw 26. Therefore, in the substrate holder 1, the screw 26 itself for attaching the clamp 20 to the block 13 also serves as the holding means described in the claims.

The stopper 30 is supported by the frame 12 on the side of the block 13, and the tip end of the pressing piece 23 of the other sandwiching member 21 which is not supported by the block 13 at the upper and lower ends thereof. An abutting portion 31 is formed which abuts on the clamp 20 to regulate the clamp 20 so that the clamp 20 is rotated only in a range of 180 degrees up and down.

The substrate holder 1 configured as described above is
As shown in FIGS. 3A and 4A, after pressing the pressing pieces 23 in a state where the holding pieces 22 are horizontal to separate the holding pieces 22 from each other, the board is inserted between the holding pieces 22. When the pressing piece 23 is released, the substrate is clamped by the clamping member 21 and held in a horizontal state.

In this state, after performing a predetermined work such as inserting the lead wire of the element into the through hole,
As shown in FIGS. 3B and 4B, when the clamp 20 is rotated, the pressing piece 23 abuts the abutting portion 31, so that the clamp 20 rotates 180 degrees and stops. At this time, the board sandwiched by the clamps 20 is just inverted, and the work of soldering the lead wires can be performed immediately.

In the substrate holder 1, the clamp 20 as described above is used, but the clamp 20 is not particularly limited to this, and any plate-like member such as a substrate can be clamped. Anything may be used as long as it is used.

Further, in the substrate holder 1, the screw 26 for attaching the clamp 20 is clamped as described above.
However, the present invention is not limited to this, and a clamp such as a latch may be used as the holding means to hold the clamp 20 at a predetermined position.

If the stopper 30 is provided,
Although it is preferable because the unnecessary movement of the clamp 20 can be regulated, the stopper 30 is not always necessary, and the form thereof does not matter as long as it performs the same function.

[0018]

As described above, according to the substrate holder of the present invention, the clamp for sandwiching the substrate is rotatably attached to the base so that the sandwiched substrate is reversed at the same position, and the clamp is fixed by the holding means. Since the clamps are held in position 1, the clamped substrate can be easily flipped by simply rotating the clamp, and even when it is necessary to process on both sides of the substrate, the clamped substrate can be clamped as many times as in the past. Or
There is no need to remove it, improving workability.

Particularly, in the case where the stopper is provided,
Workability is further improved because unnecessary rotation of the clamp can be restricted.
