Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention mainly relates to a method of irradiating light which is useful for repairing relatively small dents in an automobile body without using a conventional sheet metal coating technique, and to implement this method. Irradiating device that can perform the irradiation.

[0002]

2. Description of the Related Art Conventionally, dents and wounds of automobile bodies, regardless of their size, are all repaired by so-called sheet metal and painting processes. However, since the method requires sheet metal technology and coating technology, there is a problem that the cost increases.

[0003] Further, in the repair by sheet metal and painting processes, since the entire paint color changes due to burnout or fading depending on the period of use of the car, the repair location is
It was extremely difficult to paint according to the surrounding paint color.
Therefore, if dents can be repaired without the need for repainting,
It can be said that both labor and cost are greatly advantageous.

[0004] In view of these points, minor dent scratches
Techniques for repairing without the need for repainting were developed and used in practice. In this technique, a bar-shaped tool dedicated to restoration is applied to the back surface of the dent portion of the automobile body, and the dent is pushed out from the back surface to the front surface to restore the dent. Extruding the entire dent to be flush with the surface requires considerable skill and requires criteria to determine if the dent has been restored flush with the original surface.

[0005] Therefore, in the above-mentioned repair technique, in order to determine whether the dent has returned to the same surface as the original surface, one or two dents, for example, such as a fluorescent lamp straight tube, are provided at the dent repair location. The repair technician irradiates the light of the linear light source of the same width, repairs it while observing the reflection of the light from the light source, and determines whether the dent has been restored to the same surface as the surrounding surface. However, they are working.

[0006] However, the inventor of the present invention determines whether or not the dent is in the same order as the original surface by the restoration while observing only the reflection of light from one or two linear light sources having the same width. When the same person looks at the naked eye while performing the restoration work, it is easy for an illusion to occur due to fatigue of the eyes and the like, and it is difficult to make an accurate determination.

[0007]

SUMMARY OF THE INVENTION In view of the foregoing, the present invention makes it possible not only to prevent the visual illusion from occurring in the above-mentioned dent repair, but also to easily determine the delicate repair condition visually. It is an object of the present invention to provide a method for irradiating light, and an apparatus for irradiating light.

[0008]

SUMMARY OF THE INVENTION The object of the present invention, which has been made to solve the above-mentioned problems, is to provide an irradiation method comprising a linear light source and another linear light source which is parallel to the light source and has a narrower light irradiation width. The method is characterized in that the light of the shape light source is applied to the concave surface to be repaired.

An apparatus for realizing the above-described irradiation method of the present invention comprises two fluorescent lamps in which the light irradiation width of one fluorescent lamp is formed narrower than that of the other on the front surface of the substrate. Are detachably provided and provided in parallel. Here, the substrate is attached to the support base so as to be movable up and down, up and down, and left and right, and is attached to the support base so that the irradiation angle of light can be freely changed.

[0010]

Next, an embodiment of the present invention will be described with reference to the drawings. FIG. 1 is a perspective view from the front side of an example of the irradiation apparatus of the present invention, FIG. 2 is a perspective view from the back of an example of a support base in the apparatus of FIG. 1, and FIG. 3 is a front view schematically showing reflection of light. FIG. 4 is an enlarged cross-sectional view of the fluorescent lamp apparatus.

In FIG. 1 and FIG. 2, reference numeral 1 denotes a plate-shaped substrate which is formed in a rectangular shape when viewed from the front, and here, the front is formed in black. Reference numerals 2 and 3 denote fluorescent lamp fixtures mounted on the front surface of the substrate 1 in a vertically and parallel arrangement, and upper and lower sockets.

c, reflecting surfaces 2d and 3d disposed in the protective tube, and straight tube fluorescent tubes 2e and 3e mounted on sockets 2a and 2b respectively in front of the reflecting surfaces 2d and 3d in each tube. Is formed from.

The irradiation device L of the present invention is a mask 3f made of an appropriate light-shielding material to shield light from the front side to the rear side of the protective tube 3c of the device 3 among the devices 2 and 3.
And the width of the light irradiation surface is formed to be narrower than that of the device 2. Light-shielding materials include light-shielding paints and
Select an appropriate one from the list and the board. Further, the width of the light irradiation surface that is not shielded by the mask 3f may be variable. To make the mask variable, the mask 3f may be provided in two parts on the circumference of the protective tube 3c, and this may be rotated and moved along the tube 3.

Reference numeral 4 denotes a support base for the substrate 1 provided with fluorescent lamps 2 and 3 as irradiation means on the front surface. In this embodiment, a tripod for a camera is used. Here, 4a has three legs
A base block having an upper end of 4b openably and closably mounted and supporting a column 4c at the center so as to be able to move up and down. The support base 4 is formed of this block 4a and a platform 4d provided at the upper end of the column 4c. Have been. 4e is an auxiliary link for connecting the leg 4b and the support 4c.

A camera platform 4d is provided at the upper end of a column 4c with a camera platform base d1 provided so as to be pivotable and fixable in a plane, and a bracket d2 provided in front of the base d1 so as to be pivotable and fixable in a vertical plane. ,
A top block d3 is provided at the upper end of the bracket d2 so as to be pivotable and fixable with respect to a horizontal axis. The rear surface of the substrate 1 is applied to the front surface of the top block d3, and is detachably mounted by mounting bolts d4. ing. In addition,
d11, d21, and d31 are operation knobs or operation levers for allowing and fixing the operations of the above-described camera platform constituent members d1 to d3d;
Is an operation handle for moving the column 4c up and down, and constitutes an example of the irradiation apparatus L of the present invention. In the present invention, the configuration of the camera platform 4d is an example, and any structure other than the above may be used as long as the substrate 1 can be freely changed in all directions and fixed.

The above-described irradiation apparatus L of the present invention is used in the following manner as an example. First, the device L of the present invention is disposed so as to face a dent portion of an automobile body,
In addition, the fluorescent lamp fixtures 2 and 3 are directed parallel to the recessed body surface by adjusting the support base 4.

In this state, when only the fluorescent lamp of the appliance 2 among the appliances 2 and 3 is turned on, as shown schematically in FIG. The reflection mL of the illumination light looks thicker than the body surface B having no surface.

Therefore, the above-mentioned bar-shaped tool is repaired by applying the dent D to the back side and extruding the dent D so as to restore the dent D to the front side of the body. Dent D
Is pushed out to the front side, does the reflected image mL of the light of the device 2 that has been reflected thickly become less different from the portion B without dents as schematically shown by the dotted line in FIG. ,
Disappears. If the difference disappears, the restoration is complete.

However, in practice, the reflected light mL of the device 2 reflected on the body surface B is not so clear in its outline, so that the portion where the dent D is repaired is completely different from the body surface B without dent. It is not easy even for a fairly skilled technician to determine whether a person has become the same.
In addition, since the same reflection mL is continuously observed during the restoration work so far, it is more difficult to discriminate subtle differences due to eye fatigue, familiarity, and the like.

Therefore, in the present invention, the other appliance 3 is turned on (the appliance 2 is turned off), the light is irradiated to the above-mentioned restored dent D, and the reflection smL of the light is observed. At this time, the reflected smL reflects a small difference even if there is a small difference between the portion B having no dent and the portion where the dent D has been restored due to its narrow width. Therefore,
The technician performs the final adjustment repair of the dent repair by the rod-shaped tool while irradiating the narrow illuminating light to the dent D under repair and observing it.

As a result, it is possible to quickly and extremely accurately perform dent repair of an automobile body, which has conventionally been difficult to determine whether there is a delicate or minute difference between a repair surface and a non-dent portion. Is now possible.

In addition, the apparatus used for this purpose only needs to add one irradiation light source with a reduced light irradiation width to the conventional apparatus, so that the apparatus itself can be easily manufactured and provided at low cost. It is extremely large that it contributes to the spread of dent repair technology of the body which does not perform sheet metal and painting.
