In the measurement process of conventional thermometer manufacturing, in order to properly combine a thermometer material Eo filled with mercury as shown in FIG. 1 with a scale plate, that is, a dial S as shown in FIG. They relied on manual labor as described below.

Once upon a time, thermometer material E shown in Figure 1.

After placing the silver tank part H in a constant temperature bath at 37°C for several minutes, the worker manually marks the surface of the glass outer tube corresponding to the position of the tip of the mercury column at that time. do.

Furthermore, it is placed in a constant temperature bath at 41°C, and then marked with markings in the same manner.

FIG. 3 shows the thermometer material E1 after marking.

Furthermore, the worker measures the distance between the marked lines L1 and L2 at 37°C and 41°C, respectively, using a ruler, and selects various types of dials S whose display scales match the distance between 37°C and 41°C. select one of the dials S, and select this dial S from the line L1.
．． Align it with L2 and attach it to the thermometer material E1.

In such a manual manufacturing process, errors caused by the operator are large and affect the accuracy in the final inspection.

For example, line L1. There is a risk of an error in the position of L2, an error in measuring the distance between the marked lines L1 and L2 at 37° C. and 41° C., and a mistake in selection of the dial S.

Therefore, there was a strong hope that accuracy could be improved by making the work free from errors due to individual differences or mistakes.

Since it was an old manual process, there was a limit to productivity, and improvements in this respect were slow.

Hereinafter, one embodiment of the present invention shown in FIG. 4 will be described.

In Fig. 4, 1 is a conveyor line that conveys the thermometer material, 2 is a loading machine that sets the thermometer material on the conveyor line 1, and 3a and 3b are image pickup devices, etc. that measure and detect the position of the tip of the mercury column of the thermometer material. electronic detection device using

A computer controls the marking devices 5a, 5b and the sorting machine 8.

Next, the operation of the thermometer manufacturing auxiliary device according to the present invention configured as described above will be explained.

1. First, a thermometer element t as shown in FIG. 1 is set on a conveyor line 1 by a loading machine 2.

Although not shown, the conveyor line 1 is equipped with a chuck for gripping the body temperature meter material E.

is fixed to a chuck in the vertical direction and is transferred by the Con-Align 1.

The thermometer material is transferred by a conveyor line 1 and first enters a thermostat 6 at 37°C.

When moving the thermometer inside the thermostatic chamber 6, it is necessary to allow sufficient time for the mercury column of the thermometer T to reach 37°C.

Once the thermometer material leaves the constant temperature bath 6, it is rotated about the vertical direction by the rotating device 4a.

This is so that the mercury column can be detected by the electronic detection device 3a.

The computer 9 constantly checks whether the water column of the thermometer material can be measured through the physical detection device 3a, and when the thermometer material is rotated to a position where it can be placed on the mouth side, it issues a command to the rotating device 4a to stop rotating. Outputs a signal to stop rotation.

At this point, the computer takes in data such as image data of the thermometer material captured by the electronic detection device, analyzes the data, measures the position of the tip of the mercury column of the thermometer material, and stores it.

Next, the thermometer material is transferred to the marking device 5a by the conveyor line 1. At this time, the thermometer material is marked on the surface of the glass outer tube corresponding to the tip position of the mercury column stored in the computer 9. A signal is output to the device 5a to make it ink out.

The thermometer material that has been stamped at 37℃ is on conveyor line 1.
After this, sorting is carried out in front 1 of table 8, where exactly the same operation as that performed during marking at 37°C is carried out using electronic detection device 3b, rotation device 4b, and marking This is done using device 5b.

After marking 41'C, the thermometer materials are transferred to the sorting table 8 by the conveyor line 1.

At this point, the computer 9 has detected the electronic detection device 3a,
Based on the detection of step 3b, the difference in the position of the tip of the mercury column at 37°C and 41°C on the thermometer material is calculated, and the sorting is done in which block among the multiple blocks corresponding to the dial classification (based on the scale interval) towards the table 8. Determine whether it belongs.

When the thermometer material reaches the sorting table 8, the computer outputs a signal to the sorting table 8, and the sorting gate of the block to which the thermometer material belongs, which was previously determined, is opened.

Since this block and dial classification correspond, automatic measurement and dial combination can be performed.

The thermometer material with the dials assembled in this way is inserted into the thermometer material in alignment with the marking lines, and the necessary finishing treatments are performed to complete the thermometer.

A large number of thermometer materials are set and transported at appropriate intervals on the conveyor line, which not only enables efficient measurement and dial combinations, but also allows for sorting without the help of workers. As a result, the accuracy of the thermometer is improved because there are no errors due to individual differences or mistakes.

In this way, the work of assembling the thermometer material and the dial plate is made uniform, making it possible to manufacture a thermometer with higher accuracy than in the conventional manual work.

Productivity is also improved because the meter button and dial can be automatically combined without the intervention of the operator.

Note that the present invention is not limited to the embodiments described above and shown in the drawings, and can be modified in various ways without changing the gist thereof.

For example, the temperature standard only needs to be able to select the type of dial, so if there are two different values within the measurement range of a thermometer, 37℃, 4℃, etc.
There is absolutely no problem with values other than 1°C.

(Of course, the greater the difference between the two values, the better the determination accuracy will be.

)Also, the marking is simply for positioning when installing the dial, so even if it is at one of the temperature reference positions, one point corresponding to the other arbitrarily set temperature (this In this case, the mercury column heights for both of the two temperature standards are detected and then marked off).

As described above, according to the present invention, the thermometer manufacturing auxiliary device greatly improves the work process of thermometer measurement and temperature plate combination in the manufacture of thermometers, and as a result, allows high-precision thermometers to be manufactured with high productivity. can be provided.
