Lamp image furnaces reflect the emitted light from a lamp on a mirror and irradiate it onto the workpiece for heat treatment.Compared to other heating furnaces, the lamp image furnace is more energy efficient and can process quickly. Because it has the advantage of not contaminating materials, it is widely used in various industrial applications.

By the way, in the past, there were many systems in which a single elliptical mirror was used to focus the light on the object to be processed, but in this method, the elliptical mirror was used to focus the light on the object to be processed, in order to facilitate the loading and unloading of the object. Since it does not completely surround objects, the light inevitably diffuses to the outside. Furthermore, since the light emitting part of the lamp is not a perfect point but has a size, even if this light emitting part is placed at the first focal point of the mirror, it cannot be completely focused on the workpiece placed at the second focal point. There is a problem in that the light usage efficiency is not high because it does not emit any light and also heats the processing table. Furthermore, it has been difficult to observe the object to be processed by, for example, measuring the temperature of the object during the heat treatment.

〔考案の目的〕[Purpose of invention]

Therefore, the present invention efficiently focuses the emitted light from the lamp on the object to be treated, resulting in high energy usage efficiency.
In addition, the purpose is to provide a lamp image furnace that allows the observation of the workpiece by measuring the temperature of the workpiece during heat treatment, and also allows easy loading and unloading of the workpiece. It is something to do.

A support plate 12 is arranged on the substrate 11, and a rail 13 is attached to the support plate 12. A slide shifter 14 is fixed to the lower surface of the first mirror 2 via a cooling plate 9, and this slide shifter 14 slidably straddles the rail 13. The first mirror 2 is a spherical mirror whose aluminum alloy surface is plated with gold to have a high reflectance of infrared rays, and an observation hole 21 is bored in the center thereof. A receiving frame 16 is mounted on the first mirror 2, and a transparent processing stage plate 1 on which a processing object 10, which is an alumina capacitor for electronic parts, for example, is placed is fitted into the receiving frame 16. Therefore, the slide shifter 14 serves as a movable holding stand that holds the processing stage plate 1 and the first mirror 2 integrally. This processing stage plate 1 is made of a transparent material such as quartz glass, transparent magnesia, or saphire.When the processing temperature is about 800°C or less, quartz glass is used, when the processing temperature is about 1500°C or less, saphire is used, and when the processing temperature is about 1500°C or less, it is made of sapphire.
If the damage is below that level, it is best to use transparent magnesia. The portion on which the object to be processed 10 is placed is located at the center of the spherical surface of the first mirror 2. Immediately below the observation hole 21, a half mirror 3 consisting of an infrared reflective filter is placed at an angle of 45 degrees, through which visible light, which is the main radiation component of the lamp 7, is transmitted. The radiation component from the object to be processed 10 is reflected at right angles, and a radiation thermometer 4 made of a silicon detection element is placed in the optical path. This silicon detection element has a wavelength
It has the property of detecting infrared light centered on 0.9 μm light.

A spherical mirror 5 made of aluminum alloy and plated with gold is fixed to the upper surface of the spacer 15 erected on the substrate 11, and on top of this spherical mirror 5 is an elliptical mirror 6 made of Pyrex glass plated with gold. Although they are arranged in series, the first focal point of the elliptical mirror 6 and the center of the spherical mirror 5 coincide. The spherical mirror 5 and the elliptical mirror 6 constitute a second mirror, which surrounds the processing stage plate 1 from above. The processing stage plate 1 is located at the second focal point of the elliptical mirror 6. A lamp 7 made of a halogen incandescent bulb with a rating of 100V and 1000W is held by a holder 17 and inserted into the elliptical mirror 6.
1 is located at the first focus of the elliptical mirror 6 and at the center of the spherical mirror 5. Therefore,
The emitted light from the lamp 7 is reflected by the elliptical mirror 6 and condensed onto the workpiece 10 located at the second focal point, and the light incident on the spherical mirror 5 returns to the light emitting section 71 located at the center and returns to the elliptical mirror 6. The light is reflected and focused on the object 10 to be processed. 1500℃ if lamp 7 is the above-mentioned incandescent bulb
However, when heating the object 10 to a temperature higher than this temperature, it is better to use a discharge lamp instead of an incandescent lamp. It is located at the center of the spherical mirror 5.

Then, the slide shifter 14 is moved to take out the processing stage plate 1 from the second mirror consisting of the spherical mirror 5 and the elliptical mirror 6, and the thin plate of the alumina capacitor, which is the object to be processed 10, is placed on the processing stage plate 10. , move the slide shifter 14 again to return the processing stage plate 1 to the predetermined position within the second mirror. When the lamp 7 is turned on, the emitted light is directed toward the object to be processed 10 and heats it. At this time, since the processing stage plate 1 is surrounded by the second mirror, the light is not diffused to the outside and all the light is focused on the object to be processed 10. Since the processing stage plate 1 is transparent, the light directed toward the processing stage plate 1 passes through it, is reflected by the first mirror 2, and is focused on the object to be processed 10 again, so the light utilization efficiency is very high. expensive. Furthermore, since the processing stage plate 1 is transparent, infrared rays emitted from the object to be processed 10 pass through it, and the temperature can be measured by the thermometer 4 to observe the state of the object to be processed 10. . Then, when the processing is completed, the slide shifter 14 is moved to take out the processing stage plate 1 from the second mirror and the workpiece 10 is carried out, but since the workpiece 10 can be carried in and carried out by moving the slide shifter 14, Although the processing stage plate 1 is surrounded by the second mirror, it has the advantage of being easy to handle.

[Effects of the invention] As explained above, in the lamp image furnace of the invention, since the transparent processing stage plate is surrounded by the second mirror from above, the light is not diffused to the outside, and By placing a concave first mirror in the holder, the emitted light that did not hit the object to be processed can pass through the transparent processing stage plate again and be heated from below, so that the emitted light from the lamp does not reach the object to be processed. It is efficiently oriented, has high energy usage efficiency, and can be used to observe the workpiece by measuring the temperature of the workpiece during heat treatment, and it is also easy to put in and take out the workpiece. Can be used as a lamp image furnace.
