RoboNova does not allow operator fault in the cleaning of mass-produced parts and always extracts products according to the cleanliness criteria. RoboNova reduces operation costs and it provides more products with less labor & people. These machines, which are suitable for working 24/7, operate in a fully automatic and faultless manner in accordance with the desired cleanliness criteria.
In addition to our industry-specific solutions, we are able to work with our customers to create special processes for RoboNova. We will meet our customers with optimum machine design with washing tests and chemical selection. RoboNova’s cleaning process consists of the following process steps. The cleaning process is created with various variations of these process steps.
Pre-wash: In order to increase the life of the ultrasonic cleaning bath, it is often added to the cleaning process for cleaning of very dirty and / or oily parts. The pre-wash operation is performed by ultrasonic power or by turbulence.
Ultrasonic cleaning: The dirt on the part is removed from the surface by the cavitation effect generated by the ultrasonic sound waves sent to the liquid and by the help of the correct cleaning agent. The biggest advantage of ultrasonic cleaning systems is that it easily removes dirt from cracks and holes that are difficult to reach.
Rinsing: Most of the cleaning agents used must be removed by rinsing after the cleaning step. The rinsing quality can be increased and the duration can be reduced by the circulation or ultrasonic system.
Passivation: It is the process of protecting the cleaned parts against oxidation and corrosion. High iron contented parts should be subjected to passivation after cleaning.
Hot air dryer: For fast packing and stacking, the parts are dryed with hot air. If parts are not dried, contamination is easier due to external factors.
Vacuum dryer: If parts are desired to dry quickly or completely and the parts have water-bearing indentations and outputs, vacuum dryer added to the system. It is also preferred if a high cleaning criterion is expected from the product coming out of the machine.
We have different solutions for the transport of the cleaning basket in accordance with the weight of the basket;
Transport systems: In the transfer of the cleaning baskets to the next treatment tank, the ball screw or rack mechanisms operating with the PLC controlled fully automatic servo motor can be added to the washing line. For low weight baskets, it is also possible to transport with PLC controlled pneumatic systems.
Some of the options we offer to our customers for higher quality material cleaning are as follows;
Filtration: The parts leave the pollution on the tank during the cleaning process. Solid particles in the tank are can be removed from the tank by filtration system. This increases the service life and cleaning quality of the solution. Thanks to the cartridge type filters we use, the filter cassette can be cleaned periodically.
Oil seperator: During the cleaning of the oily parts, the surface of the solution is covered with an oil layer. If this layer is not removed from the solution, the target parts are re-contaminated when they are transferred from tank. In order to prevent this, the oil layer on the surface of the solution is transferred to seperation tank and the oil is separated from the solution by various methods.
Steam suction system: The steam from the hot tanks is absorbed from the upper part of the tank without spreading to the environment and transferred to the ventilation system. Thus, the amount of chemical vapor released into the factory environment is minimized. The steam suction fan in the ceiling of the machine is available as standard.
Automatic filling and discharging system: Water filling and draining system can be controlled by PLC with electric valves or solenoid valves. With this additive, when the amount of liquid in the tank is reduced, the machine will continue to process by filling water without stopping.
Automatic chemical dosing system: During the preparation of the solution, the cleaning agent can be added to the tank automatically. In this way, process errors that can occur due to different agent ratios are prevented. Working together with the automatic filling system, the same ratio of chemical is added to the tank at every water addition.
