るものである。DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a liquid coating device used when applying a 7lux liquid to a printed circuit board on which electronic parts are fixed, for example, and which prevents an increase in flow resistance in a coating liquid supply path and uses ultrasonic waves. The aim is to always achieve stable atomization using an atomizer.

霧化不能になりやすい。In the conventional apparatus of this kind, fine particles of liquid are generated in a container by an ultrasonic atomizer, and these particles are transported by the entire airflow and ejected from an opening at the top of the container to be deposited on the object to be coated. In addition, the liquid is supplied from the tank to the atomizing surface through a pipe and a passage within the ultrasonic atomizer via a shut-off valve, depending on the head pressure. In this case, if the alcohol component as a solvent in the flux liquid, which is a mixed liquid of flux solids and alcohol, evaporates, it becomes extremely sticky and may cause a decrease in the amount of liquid supplied due to partial contraction of the supply passage. Atomization tends to become impossible due to increased vibration load due to adhesion to the atomization surface of the tip of the ultrasonic atomizer.

This is because when the device is stopped, the alcohol component in the flux liquid gradually evaporates and releases from the thin film of 7lux liquid that remains on the atomizing surface of the ultrasonic atomizer and the passage that is open to the atmosphere, causing the above problem. was occurring.

音波振動する。First, the electrode plate 6 and the rear metal body 7 of the plurality of ultrasonic atomizers 1
When high frequency power is applied from an oscillator (not shown) between the electrode plate 6 and the electrostrictive vibrator '6, a current flows from the electrode plate 6 to the front metal 2 and rear metal 7 on the ground side. At this time, the electrostrictive vibrator 6 is displaced in the thickness direction and vibrates ultrasonically at a frequency set at 30 to 45 K[lz]. As the vibrations propagate to the front metal 2, the atomization surface 4 vibrates ultrasonically with an amplitude of 10 to 20 microns.

。Next, open the delivery path for the 7 lux liquid 21 of the cock 19, and pump the 7 lux liquid 21 in the tank 20 to the pressure difference or pump 2.
When the atomizing surface 4 is guided through the pipe 18 by the drive of the
It is atomized to a particle size of . □The fine particles of the flux liquid 21 generated in the container 12 are carried upward by the air flow and are ejected from the transport in opening 13, and hit the printed board 22 and adhere thereto.

回転又はポンプ２６の駆動を断てばよい。When stopping the coating operation, use an ultrasonic atomizer 1° blower 17. While the pump 27 continues to drive, turn on the three-way cock 1.
9, the delivery of the 7lux liquid 21 is cut off, and the cleaning liquid 23 is
t-supply. As a result, the flux liquid 21 is pushed out in the order of the pipe 18 and the passage 3 of the ultrasonic atomizer 1, and the supply of the cleaning liquid 23 is stopped when the 7lux liquid 21 disappears on the atomization surface 4. This can be done by cutting off the rotation of the three-way cock 19 or the drive of the pump 26.

り効果的に排出できる。Further, even after the atomization surface 4 has been cleaned, the cleaning liquid is supplied for a certain period of time and the ultrasonic atomizer 1 is driven, so that fine particles of the cleaning liquid are scattered into the container 12 and the flux liquid 21ζ adheres to the wall surface of the container 12. The liquid also increases in fluidity and flows down to the bottom and is discharged into the lower tank 16. In this case, if the blower 17 is stopped and the container 12
The cleaning liquid 23 does not spray out through the upper openings 1 and 3, making it sanitary and safe, and the 7lux liquid 21 in the container 12 can be discharged more effectively.

給ができる。また。(1) By ensuring that the cleaning liquid 23 is supplied when the device is stopped, a series of supply passages and atomization surface 4 are created.
No flux liquid 21 remains. Therefore, upon restart, the resistance of the passage does not increase, and the flux liquid 21 can be stably supplied in a constant quantity. Also.
霧化面４にもフラックス液２１の粘着物がたい積せず常

２６ｆ、用いる場合は、このポンプ２５内部も洗浄され
安定した供給が維持される。Sticky matter of the flux liquid 21 does not accumulate on the atomization surface 4, and the device can always be started in a stable atomization state. If the Mayu pump 26f is used, the inside of this pump 25 is also cleaned to maintain stable supply.
舜） 洗浄液２３を供給してつる間も超音波霧化器１を

体の初期性能を長く維持でき、また掃除の必要もない。Shun) While supplying the cleaning liquid 23, the ultrasonic atomizer 1 is driven to atomize it, thereby removing the flux liquid 21 adhering to the entire atomization surface 4 and the inner wall of the container 12, thereby improving the initial performance of the entire device. It can be maintained for a long time and does not require cleaning.
（３） 洗浄液２３を供給している間、送風機１７を

壁にふれて流下し下部タンク１６に排出される。(3) While the cleaning liquid 23 is being supplied, by stopping the blower 17, the fine particles of the cleaning liquid 23 are removed from the container 12.
It does not spout out from the upper opening 13, but instead fills the container 12, touches the inner wall, flows down, and is discharged into the lower tank 16.
従って室内に洗浄液２３の微粒子が放散されず安全且つ
衛生的である。また容器１２内壁はぼ全面にわたって付
着したフラックスを除去できる。Therefore, fine particles of the cleaning liquid 23 are not dispersed into the room, making it safe and sanitary. Furthermore, the flux adhering to almost the entire inner wall of the container 12 can be removed.
以上のように本発明によれば超音波霧化器が塗布液体で
汚れ１次回の運転に支障をきたすことがなくなる。As described above, according to the present invention, the ultrasonic atomizer is not contaminated with the coating liquid and does not interfere with the first operation.
