[Industrial application field]

This invention allows the table surface to be moved left and right, up and down, and also allows for symmetrical objects to be mounted. This invention relates to a movable heating table that can be heated.

0002

[Conventional technology]

FIG. 2 is a block diagram of a movable heating table showing a conventional example. Traditionally, this The movable table for heating the seeds is, for example, the table on which the sample 1 is mounted, as shown in Figure 2. a heater 7 that heats the table 2, and a temperature that measures the temperature of the table 2. A temperature controller that inputs the output values of the measuring device 8 and the temperature measuring device 8 and controls the heating degree of the heater. It is equipped with a control section 5.

0003 Next, the operation of this heating movable table will be explained. First, the sample you want to heat. Place food 1 on table 2. Next, an arbitrary temperature is set in the temperature controller 5. warm The heater 7 is heated by the temperature controller 5 supplying current to the heater 7. Canada The heat from the heater 7 is transferred to the table 2, and the sample 1 is heated. Also, it is connected to table 2. The temperature of the table 2 is measured by a temperature measuring device 8 connected to the table 2. This measured The results are fed back to the temperature controller 5. The temperature controller 5 returns the temperature from the temperature measuring device 8. The output to the heater 7 is such that there is no difference between the returned result and the arbitrary temperature set above. A force current is applied to heat the table 2. Then repeat the previous series of actions. By doing so, the temperature of the table 2 can be maintained at the desired temperature set in the temperature controller 5. It will be done. As a result, the temperature of sample 1 can also be maintained at the temperature set in temperature controller 5. It was thought that it would be possible.

[Problem that the idea aims to solve]

With this conventional movable heating table, the temperature of the table is controlled. There was a problem in that the temperature of the sample surface could not be accurately controlled. Also, thermal properties In order to control the surfaces of several samples with different temperatures to the same temperature, it is necessary to The trouble of having to change the temperature of the table for each sample in consideration of physical properties There was a time.

[0005] The purpose of this invention is to solve this problem without changing the temperature setting for each sample. By providing a movable heating table that can heat the sample to the desired temperature. be.

[0006]

[Means to solve the problem]

The movable heating table of this invention irradiates heat rays onto the sample placed on the table surface. Enter the light source to detect the surface temperature of the sample, a thermometer to detect the surface temperature of the sample, and the measured values of this thermometer. and a temperature control section that adjusts the amount of heat rays from the light source.

【Example】

Next, the present invention will be explained with reference to the drawings.

[0008] FIG. 1 is a block diagram of a movable heating table showing an embodiment of the present invention. this The movable heating table has a light source lamp that irradiates the sample 1 with infrared rays, as shown in Figure 1. 3, a surface thermometer 4 for measuring the surface temperature of the sample 1 to be heated, and a surface thermometer 4. Input the output of , compare the set temperature with the output value, and output the difference signal. The output current of the control unit 5a and the temperature control unit 5a is input to the light source lamp 3. A light amount adjuster 6 is provided to adjust the amount of light.

[0009] Next, the operation of this heating movable table will be explained. First, the temperature control section 5 Set the desired temperature at a. Next, the light source lamp 3 is turned on and the sample 1 is heated. The surface thermometer measures the temperature of the surface of sample 1, and the measurement results are sequentially sent to the temperature control section. 5a. The temperature controller 5 receives the input measurement results and the set desired temperature. If the input measurement result is smaller than the set arbitrary temperature, the light source lamp is A signal is output to the light intensity adjuster 6 to increase the light intensity of the lamp 3, and the input result is set. A light amount adjuster 6 is configured to reduce the amount of light from the light source 3 if the temperature is higher than a predetermined arbitrary temperature. Outputs a signal to. Then, the light amount controller 6 controls the light source lamp 3 according to the input signal. Adjust the light intensity. By repeating these operations in this way, the surface of sample 1 is The temperature of the surface is kept constant at an arbitrary temperature set in the temperature controller 5.

[Effect of the idea]

As explained above, the movable heating table of the present invention heats the sample surface with hot wire. , the temperature of the sample surface is measured and the result is fed back to the temperature control section for control. It is possible to accurately control the temperature of the material surface and to consider the thermal properties even for samples with different thermal properties. This has the effect of being able to control the temperature of the sample surface without worrying.
