Description

DETAILED DESCRIPTION OF THE INVENTION [Industrial Application Field] The present invention relates to an optical cleaning device using a mercury lamp or the like that emits light having a cleaning effect such as in the ultraviolet spectrum.

[Prior Art] Conventionally, optical cleaning devices using low-pressure mercury lamps that emit light in the ultraviolet line spectrum of 253.7 nm and 184.9 nm have been used for sterilizing and cleaning various objects to be cleaned. There is.

In conventional optical cleaning apparatuses, the object to be cleaned is placed directly under a mercury lamp, and the entire object to be cleaned is irradiated with ultraviolet rays to perform cleaning.

[Problem to be solved by the invention] Conventional optical cleaning equipment has a structure that cleans the entire object to be cleaned by irradiating ultraviolet rays, so even if local cleaning is not possible and cleaning of a part is necessary, the entire object can be cleaned. Cleaning was not possible efficiently. In particular, it is not possible to efficiently partially clean three-dimensional objects or complex structures, and the cleaning effect is low because the ultraviolet rays are dispersed over the entire area.

The present invention has been made in view of the above-mentioned shortcomings of the prior art, and it is an object of the present invention to provide a light cleaning device that enables local cleaning and improves the cleaning effect by concentrating cleaning ultraviolet rays and irradiating them locally onto the object to be cleaned. purpose.

[Means for Solving the Problems] In order to achieve the above object, a light cleaning device according to the present invention includes a light source that emits light in a spectrum that has a cleaning effect;
A light guide means for guiding the light from the light source to the object to be cleaned is provided.

[Operations] Light from a light source having a cleaning effect is guided to the part of the object to be cleaned by a light guiding means consisting of an optical system such as a mirror lens and/or an optical fiber.

[Embodiment] FIG. 1 is a basic configuration diagram of an embodiment of a light cleaning device according to the present invention. A low-pressure mercury lamp 1 that emits ultraviolet rays is mounted inside a reflector (shape) 2.

This mercury lamp 1 has a cleaning effect of 253.7 na.
and a lamp that emits an ultraviolet line spectrum of 184.9 nm. 1 g of ultraviolet light of 4.9 nm has a particularly ozone generating effect, and this ozone cleans the object to be cleaned (not shown) together with the ultraviolet light of 253.7 nm. Reflector 2
A mirror 3 that reflects ultraviolet rays is disposed below. This mirror 3 may be, for example, a dichroic mirror that transmits visible light and efficiently reflects ultraviolet light. The end of the optical fiber 4 is placed at the position where the reflected light is focused by the mirror 3. This optical fiber 4 may be one or more, and is arranged up to the position of the object to be cleaned.

1g4.9nm emitted from mercury lamp 1 and 25
The ultraviolet rays having a spectrum of 3.7 nm are reflected by the mirror 3 and are focused and incident on the end of the optical fiber 4. The incident ultraviolet rays propagate within the optical fiber 4 and reach the object to be cleaned (
(not shown) is guided to a position to be cleaned, and is emitted from the end as shown by arrow A to irradiate the cleaning area. The cleaning portion of the object to be cleaned is, for example, a bonding surface of members to be bonded when used for bonding work, and ultraviolet rays are locally concentrated and irradiated onto the bonding surface from the end of the optical fiber 4. Other three-dimensional members and members with complicated shapes can also be locally cleaned in the same manner.

FIG. 2 is a schematic basic configuration diagram of another embodiment of the optical cleaning device according to the present invention. In this embodiment, a mercury lamp 1 and a reflector 2 are provided within a chamber 5. A condensing lens 6 is provided in the ultraviolet extraction part of the chamber 5. The end of the tip fiber 4 is placed at the position where the ultraviolet rays are focused by the condenser lens 6. The optical fiber 4 is arranged up to the position of the object to be cleaned (not shown) in the same way as in the embodiment shown in FIG. The chamber 5 is provided with an ozone derivation lower,
Appropriate means such as a flexible tube connected to the lead-out lower is disposed together with the optical fiber 4 up to the position of the object to be cleaned, as shown by the dashed line.

The chamber 5 is further equipped with an air supply means (not shown) such as a fan for sending out ozone in the chamber from a discharge lower.

When the mercury lamp 1 is turned on, ozone is generated in the chamber 5 by the action of 1 g of 4.9 nm ultraviolet light. The generated ozone is discharged from the outlet lower and guided to the position of the object to be cleaned by means such as a flexible tube, and as shown by arrow B, the cleaning section is sprayed and cleaned.

The condenser lens 6 mainly transmits ultraviolet rays of 253.7 nm and does not transmit ultraviolet rays of 111i4.9r+m. The 253.7 na ultraviolet light transmitted through the condenser lens 6 is focused and enters the optical fiber 4, and as in the embodiment shown in FIG.
It is guided to the position of the object to be cleaned, and the cleaning part is irradiated as shown by arrow A, and together with ozone as shown by arrow B, the cleaning part is intensively cleaned locally.

FIG. 3 is a schematic configuration diagram of yet another embodiment of the present invention. In this embodiment, the mercury lamp 8 has a long rod tube shape, and a reflecting plate 9 is provided along the upper longitudinal direction. A quartz cylindrical lens 10 is provided in the lower longitudinal direction of the mercury lamp 8.

The end portions of a large number of optical fibers 11 are continuously disposed along the cylindrical lens 1O at a condensing position below the cylindrical lens 1O.

The ultraviolet rays emitted from the mercury lamp 8 are focused by the cylindrical lens 10, enter the optical fiber 11, and are guided to the cleaning section of the object to clean the private parts of the object as in the previous embodiment.

It becomes possible to clean locally, and it is possible to locally clean the inside of a three-dimensional object or a complex structure. Furthermore, since the light from the mercury lamp is condensed and irradiated in a concentrated manner onto the cleaning area, ultraviolet rays can be effectively used for the cleaning action, increasing the intensity of ultraviolet ray irradiation on the cleaning area, resulting in a large cleaning effect.
