After the adhesive 6 is applied to one ceramic package 2 and a predetermined time elapses before being applied to the other ceramic package 2, the adhesive 6 is applied to the upper surface 98a of the adjustment base 92. That is, the primary coating means 15 and the secondary coating means 18
Means that the adhesive 6 is released at every predetermined time even at the longest.

Since the adhesive 6 is released every predetermined time even at the longest time, it is possible to prevent the adhesive 6 in the syringe barrel 84 from hardening. Therefore, the adhesive 6 hardens, and the injection barrel 84
It is possible to prevent the inside of the needle 89 and the inside of the tubular portion 88 from being closed. Therefore, the adhesive 6 can be reliably applied to the electrodes 5 of the ceramic package 2 by a predetermined amount, and the yield of the crystal resonator can be prevented from lowering.

When releasing the adhesive 6, the adhesive 6
The upper surface 98a for coating the electrode is located on the same plane as the electrode 5. Therefore, when the adhesive 6 is released, it can be applied in the same manner as when it is applied to the electrode 5. Therefore, the adhesive 6

Therefore, from the bottom dead center, the first micrometer head 93 is operated to raise the adjustment base 92 by the height T1 of the electrode 5, and the second micrometer head 94 is operated to properly set the spindle 105. Since the electrode 5 and the upper surface 98a are flush with each other, the tip surface 105a of the spindle 105 is more appropriate than the electrode 5 by the distance T2.
It is set to a position that is raised by 2 minutes. And spindle 1
The tip 89a of 05 is brought into contact with the needle tip 89a to position the injection cylinder 84, whereby the distance between the needle tip 89a and the upper surface 98a can be set to the appropriate distance T2.

Thus, the first micrometer head 9
3 and the second micrometer head 94 can be operated so that the height of the tip surface 105a from the upper surface 98a of the spindle 105 can be easily set to an appropriate interval T2. In addition, the needle tip 89
By positioning a by contacting a with the tip surface 105a and positioning the injection cylinder 84, the distance between the needle tip 89a and the upper surface 98a is
The appropriate interval T2 can be easily achieved. Therefore, the position of the injection cylinder 84 can be easily adjusted, and the time required for the preparatory work can be reliably suppressed.

Furthermore, the protruding and retracting directions of the spindles 102 and 105 are orthogonal to the upper surface 98a. Therefore, when the spindle 102 is raised by the height T1 of the electrode 5 and the spindle 105 is raised by an appropriate interval T2, the electrode 5 and the upper surface 98a are flush with each other, so that the tip surface 105a is more appropriate than the electrode 5. It is set at a position raised by the interval T2.

Therefore, the spindle 102 is raised by the height T1 of the electrode 5 and the spindle 105 is moved to an appropriate interval T.
By raising by 2 minutes, the distance between the needle tip 89a and the upper surface 98a can be easily set to the appropriate distance T2. Therefore, the position of the syringe barrel 84 can be adjusted more easily,
The time required for the preparatory work can be suppressed even more reliably.

As described above, according to the present invention as set forth in claim 1, the application means releases the adhesive at every predetermined time at the longest. Therefore, it is possible to prevent the adhesive in the application unit from being cured. Therefore, the adhesive can be reliably applied to the package by a predetermined amount, and the reduction in the yield of the crystal unit can be prevented.

According to the second aspect of the present invention, the coating means releases the adhesive at every predetermined time at the longest. Therefore, it is possible to prevent the adhesive in the application unit from being cured. Therefore, the adhesive can be reliably applied to the package by a predetermined amount, and the reduction in the yield of the crystal unit can be prevented.

According to the third aspect of the present invention, since the flat surface is located on the same plane as the electrodes of the package, the distance between the coating means and the flat surface is equal to the distance between the coating means and the electrode. For this reason, the application means can apply the adhesive when applying to the flat surface in the same manner as when applying to the electrode.

Therefore, since it can be applied to the flat surface in the same manner as when applying to the package, it is possible to reliably prevent the adhesive from being hardened in the applying means. Therefore, the adhesive can be more reliably applied to the package by a predetermined amount, and the reduction in the yield of the crystal unit can be more surely prevented.

According to the fourth aspect of the present invention, by operating the first micrometer head, the flat surface can be easily located on the same plane as the electrodes of the package. Therefore, the application means can apply the same when applying to the flat surface as when applying to the electrode. Therefore, the adhesive can be more surely applied to the package by a predetermined amount, and the decrease in the yield of the crystal unit can be more surely prevented.

The present invention according to claim 5 is from the bottom dead center,
When the first micrometer head is operated to raise the base body by the height of the electrodes of the package, and the second micrometer head is operated to raise the spindle of the micrometer head by an appropriate interval for applying the adhesive. Since the end surface of the spindle is flush with the base body, the end surface of the spindle is set at a position higher than the electrodes of the package by a distance suitable for applying the adhesive.

Therefore, by positioning the coating means by bringing the tip of the coating means into contact with the end surface of the spindle, the spacing between the coating means and the flat surface can be surely set to an appropriate distance.

In this way, by operating the first micrometer head and the second micrometer head, the height of the end surface of the spindle from the electrode of the package can be easily adjusted to an appropriate interval for applying the adhesive. it can.

Therefore, in addition to the fact that the adhesive can be surely applied to the package by a predetermined amount and the yield of the crystal resonator can be prevented from lowering, the position of the applying means can be easily adjusted and the time required for the preparatory work can be surely done. Can be suppressed.
