Description

DETAILED DESCRIPTION OF THE INVENTION A. Object of the Invention 1) Industrial application field The present invention relates to a work information display device for allowing a worker to visually recognize work information on work performed under a magnifying glass.

Such a work information display device can be used for assembling, inspection, function confirmation, experiments, or the like of devices assembled by fine components such as electronic devices.

2) Prior art In the work of soldering and wiring fine parts, for example, electronic elements to a circuit, the confirmation of the circuit, the pin arrangement of the elements, and the like are performed while referring to the drawings in which they are described. There are many.

On the other hand, in the check after assembling the circuit,
A signal output to a pin of an element is detected by a probe in contact with the pin, and is displayed on a tester or a synchrocorp for examination.

Next, an example of the prior art for performing these fine operations will be described with reference to FIG.

In FIG. 3, a ring-shaped support frame 02 is supported by an arm 01 supported by a stand (not shown), and a ring-shaped fluorescent lamp 03 for illumination is supported on a lower surface of the support frame 02. I have. A magnifying mirror 04 is supported inside the ring of the ring-shaped support frame 02. Then, for example, when performing an inspection work, the worker 05 contacts the probe 07 with the pin 06a of the element while looking at the work portion 06 below the magnifying glass 04. The detection signal detected by the probe 07 is subjected to amplification, waveform shaping, and the like in the signal processing circuit 08, and is displayed on the display unit 09. Therefore, the worker 05 works while looking at the work unit 06 and the display unit 09 alternately.

3) Problems to be Solved by the Invention By the way, at the time of the above-mentioned inspection, since a portion to which the probe is applied is fine, the probe is displaced while reading a detection signal or a detection value, and no signal is output or, in some cases, a horizontal signal is output. Contact with a power supply line running through the device, and the element may be burned out due to a short circuit or the like. Also, when assembling an electronic circuit, soldering and wrapping are performed while checking the connection information of the elements, but it is not possible to check both the drawing and the element showing the information at the same time. There is.

The present invention has been made in view of the above circumstances, and an object of the present invention is to make it possible to simultaneously visually recognize a work portion and information related to the work when performing a fine work while looking at the work portion through a magnifying glass.

B. Configuration of the Invention 1) Means for Solving the Problems In order to solve the above problems, the work information display device of the present invention includes a magnifying glass supported by a ring-shaped support frame and a magnifying glass below the magnifying glass. An information light projecting device for projecting the work information display light on the work to be performed onto the upper surface of the magnifying glass, wherein the work information display light emitted from the information light projecting device is
It is characterized in that it is configured to be deflected upward on the upper surface of the magnifying mirror.

The configuration in which the work information display light is diverted upward on the upper surface of the magnifier may be a configuration in which the work information display light is reflected on the upper surface or a configuration in which the work information display light is diffracted upward.

2) Operation In the work information display device of the present invention having the above-described features, when the worker works while looking at the work portion below from above the magnifying glass, the worker is turned upward on the upper surface of the magnifying glass. The work information display light can be visually recognized simultaneously with the work part.

3) Example Hereinafter, an example of the work information display device of the present invention will be described with reference to the drawings.

FIG. 1 is an explanatory view of a use state of the embodiment, and FIG. 2 is an enlarged side sectional view of a main part of the embodiment.

1 and 2, a ring-shaped support frame 2 is provided by an arm 1 supported by a stand (not shown).
Are supported, and a ring-shaped fluorescent lamp 3 for illumination is supported on the lower surface of the support frame 2. A magnifying mirror 4 is supported inside the ring of the ring-shaped support frame 2.
The magnifying mirror 4 is constituted by a convex lens having a flat upper surface. The worker 5 works while looking at the work portion 6 below the magnifying glass 4. And, for example, in the inspection work,
When the probe 7 is brought into contact with the probe 6a, the detection signal detected by the probe 7 is amplified and waveform-shaped by the signal processing circuit 8, and is displayed on the CRT display 9 as work information.

The CRT display 9 is housed inside a display housing case 10 fixed to the arm 1,
On the front surface of the CRT display 9, a convex lens 11 is arranged. Note that the convex lens 11 can be omitted. The CRT display 9, the display storage case 10, and the convex lens 11 constitute an information projection device K. The work information display light L displayed on the CRT display 9 and emitted from the information light projecting device K is configured to be projected on the flat upper surface of the magnifying mirror 4. The flat upper surface of the magnifying mirror 4 is provided with a reflective coating on a portion where the information display light L is incident, so that a part of the work information display light L incident thereon is reflected upward. Is configured. The reflection coating is not a total reflection coating but a partial reflection coating, and is configured to transmit a part of incident light. Further, the reflection coating can be applied to the entire surface of the magnifying mirror 4 instead of a part of the upper surface.

 Next, the operation of the above embodiment will be described.

The worker 5 works while looking at the lower working portion 6 from above the magnifying glass 4 when working in the working section 6. that time,
The work information display light L projected on the flat upper surface of the magnifying mirror 4 from the information light device K is reflected upward and heads toward the worker 5. Therefore, the worker 5 can perform the work while simultaneously viewing the work section 6 and the work information display light L.

As described above, the embodiments of the present invention have been described in detail. However, the present invention is not limited to the above embodiments, and various design changes are made within the scope of the present invention described in the appended claims. It is possible.

For example, instead of forming the upper surface of the magnifying glass on a flat surface, the magnifying glass may be formed on a spherical surface. In such a case, an image considering distortion of an image due to the spherical surface may be displayed on a CRT display. Instead of using a CRT display, the information projection device K uses various displays such as a liquid crystal display having a light source disposed on the back, a plasma display, a light-emitting diode display, an electro-chemical display, or an electro-luminescent display. It is also possible to configure. Further, the work information display light L emitted from the information light projecting device K may be diffracted upward instead of being reflected upward on the upper surface of the magnifying glass. Furthermore, the present invention can be applied not only to electronic components but also to assembly of precision mechanical components and the like.

C. Effects of the Invention Since the work information display device of the present invention is configured such that the work information display light emitted from the information light projecting device is turned upward on the magnifying glass upper surface, When performing a fine work while looking at the work portion through a mirror, the work portion and information on the work can be visually recognized simultaneously.
