This printed circuit plate washing apparatus is used for effectively washing the openings of printed circuit plates, eliminating a cleaning water after etching printed circuit plates or nameplates, degreasing aluminum plates before printing and number plates before painting and washing iron, plastic or glass plates. For these purposes, said apparatus is divided into three sections (or chambers) such as a bring-in chamber, a washing chamber, and a wash-out/finishing chamber. Further, this washing line of said apparatus is so composed that a plate to be washed may be elevated in slope with a certain fixed angle for the level line from said bring-in chamber toward said wash-out/finishing chamber, thereby a washing water being overflown to said washing chamber and to said bring-in chamber in this order through respective partition plate. And a carrying means is provided in every chamber by means of belt, chain or wire net. Said partition plate located between said bring-in chamber and said washing chamber is provided with an insertion port which is sealed by rubber-oriented elastic means. Therefore, said plate to be washed can be directly brought into a washing solution in said washing solution in said washing chamber. Besides, said washing chamber is provided with an ultrasonic wave transmitter.
An ultrasonic waves washing apparatus comprising a washing/treatment tank divided into three sections such as a bring-in chamber, a washing chamber, and a wash-out/finishing chamber, said washing-out/finishing chamber being elevated in smooth slope with a certain fixed angle from said bring-in chamber to effect smooth washing treatment, thereby causing washing water contained in said wash-out/finishing chamber to be overflown into said washing chamber and said bring-in chamber in this order through partition walls, carry means such as belts, chains or wire nets mounted in each of said three chambers, an insertion port sealed by rubber-oriented elastic means, composed at a partition wall between said bring-in chamber and said washing chamber, said articles to be washed being directly inserted into a washing water contained in said washing chamber from said bring-in chamber through said insertion port, and an ultrasonic wave transmitter means mounted in said washing chamber.
