。Oscillators are used in many electronic industries such as information equipment, communication equipment, watches, and calculators. In addition to single crystals such as quartz, lithium tantalate, and lithium niobate, the research and development of electroconductive ceramics is progressing, and various materials are now being used for the vibrating elements. The present invention relates to a method for assembling these vibrators, and is particularly effective for vibrators for wristwatches, which are required to be compact and inexpensive.

。The adhesive (3) fixes the supporting member and the tuning fork-shaped vibrating piece (1), and at the same time electrically connects it to the excitation electrode (not shown) formed on the tuning fork-shaped vibrating piece (1) (hereinafter simply referred to as the vibrating piece). It is normal for it to also serve as In the prior art, the vibrator shown in FIG. 1 was assembled by the following method. First, solder is applied in advance to the electrodes formed on the support portion of the vibrating element (1). Further, solder is also applied to the support portions of the two support members (2). If the distance between the vibrating element (1) and the supporting member (2) is narrow, it may be possible to attach the vibrating element to either the vibrating element (1) or the supporting member (2), but generally they are attached to both.

In the present invention, the object has been achieved by batching operations that were conventionally performed side by side. The present invention will be explained in detail with reference to FIGS. 2 to 5.

定量供給ができる。FIG. 4 is a perspective view of the upper surface of the airtight terminal p with solder applied thereto. In the present invention, it was decided to use solder spatter and attach it to the upper surface of the glass (6) between the two lead wires (2). As shown in Fig. 4, twist solder is applied to the upper surface of the airtight terminal set as shown in Fig. 2.
Since I used a dispenser that can adjust the amount of solder dispensed,
Quantity supply is possible.

ておいても完成振動子がショートするようなことはない
。When the state shown in FIG. 5 is established, the vibrating piece (1) that was attached to the jig will slide down between the two support members and ride on the adhered solder. When hot air is blown onto the twisted solder in this state, the solder melts, and due to the surface tension and wettability of the solder, it sticks to the electrodes formed on the supporting member and the vibrating piece, and the solder between the two supporting members separates. Therefore, even if the bending half opening is initially attached across two supporting members, there will be no short circuit in the completed vibrator.
熱風の発生源を固定しておき、キャリアを置く部分を移

たる部分を制限したい場合には、熱風の吹き出し口を絞

場合は吹き出し口をキャリアの移動方向に細長くしてや
ればよい。If the source of the hot air is fixed and the part where the carrier is placed is movable (for example, a belt conveyor), continuous soldering can be performed, which is very efficient. If you want to limit the area that hot air hits, you can narrow down the hot air outlet or provide a shielding plate, and if you want to blow hot air for a long time, you can make the outlet elongated in the direction of movement of the carrier.

前記５つの工程で振動子を組立る方法である。To summarize the configuration of the present invention explained above, 1. Set the airtight terminal on the carrier. 2. Set the vibrating piece on the jig. This is a method of assembling a vibrator through the above five steps of setting the jig and step 3 of the carrier, step 5 of applying hot air.
本発明では、ねり半田を使用し、半田の表面張力と濡れ
性を最大限利用している。In the present invention, twisted solder is used to maximize the surface tension and wettability of the solder.
本発明によれば、振動片及び支持部材への半田付が不要
であり、半田付（支持部材と振動片の固着）も自動化で
き、組立工数を大巾に削減することができた。According to the present invention, there is no need to solder the vibrating element and the supporting member, and the soldering (fixing the supporting member and the vibrating element) can also be automated, thereby greatly reducing the number of assembly steps.
