About This Product
■How to transport baskets in line batch cleaning equipment
A feature of line batch type cleaning equipment is that the work to be cleaned is placed in a basket and then cleaned and dried. It is common to incorporate multiple processes such as spray cleaning, ultrasonic cleaning, and vacuum drying, and a combination of rack and pinion and servo motors is used to transport the baskets.
By controlling the raising, lowering, and traversing of the basket with a servo motor, it is possible to easily stop it at any position, so it is possible to restore the basket without any trouble when setting it up after replacing parts.
■Mechanism and benefits of vacuum drying in line batch cleaning equipment
Vacuum drying lowers the boiling point of water and evaporates water by reducing the pressure in the tank in which the work is set. When using a metal cleaning machine, note that since it uses the workpiece's own heat, it is necessary to raise the temperature of the workpiece in advance, so hot air drying (heat exchange) is installed in the previous process. is common.
For workpieces to be cleaned made of sheet metal that do not retain heat easily, in addition to vacuum drying, it is necessary to consider a heating method that transfers heat even in a vacuum. An advantage of vacuum drying is that it can easily dry shapes that are difficult to dry, such as blind holes and tapped holes.
■Advantages and disadvantages of immersion cleaning in line batch type cleaning equipment
It is difficult to ensure the cleanability of complex-shaped workpieces by spray cleaning alone, but it may be possible to overcome this problem by immersing the workpiece in the cleaning solution or rotating the basket. It will increase. Furthermore, by combining ultrasonic cleaning, it is effective even on minute dirt, making it possible to further improve cleanliness.
The disadvantage is that it takes time to clean, usually 2 to 3 minutes per process. In addition, in order to eliminate overlap between workpieces and ensure even cleaning, it is necessary to devise measures for the equipment, such as rotating the basket.
■Types and selection of ultrasonic waves in line batch type cleaning machines
Line batch cleaning mainly consists of ultrasonic cleaning. Ultrasonic waves are installed in each process such as rough cleaning, final cleaning, and rinsing to clean parts. When using ultrasonic waves, it is necessary to set the frequency and transmission method according to the target work. When using electrolyzed ionized water as a cleaning solution, ultrasonic performance becomes particularly important, so careful selection is required.
