PRE-TREATMENT , SURFACE PREPARATION , DEGREASING & CLEANING
Thanks to the modular concept of the UCMSmartLine , multi-chamber immersion cleaning systems can be individually designed for a wide range of applications . The electrical and control system is already integrated in each module .
HEPA filters can be installed on the top of the housing , depending on the length of the system . As a rule , two flow boxes are used ; which creates a cleanroom atmosphere from the last rinsing station to the unloading station . The UCMSmartLine can also be connected to a cleanroom .
Designed for maximum process reliability as standard
Inside the system , the parts are conveyed by a standard automatic transport system with servo drive . This enables the transport speed to be adapted according to the parts being cleaned . As a result , the parts are handled extremely gently during processing . In addition to preventing damage and scratches on sensitive workpieces , it also prevents components from rising to the surface . If desired , speeds can be increased in most sections of the line to ensure a higher throughput . A further advantage of the servo drive is the part-specific lift-out from the last rinsing tank for pre-drying the parts . This helps prevent stains from forming during the subsequent drying process .
The standard version of the system has a static transport rack made of stainless steel that is designed for a maximum batch weight of 20 kg . In addition , transport racks that can be rotated along the longitudinal axis are available for bulk items requiring increased part agitation . Another type of transport rack can be rotated along the vertical axis at 200 rpm during wet processes and up to 1,000 rpm during the dry process . These racks are used , among other things , to clean microlenses in optics .
Up to nine cleaning and rinsing steps can be integrated into the cleaning system and variably equipped for use with single , dual and multi-frequency ultrasonics .
If higher throughputs are required , the system can be fitted with a second automatic transport system .
The spill-over tank developed by UCM also guarantees consistently good cleaning results in line with demands : In all of the cleaning and rinsing tanks , the media are introduced from below and pumped to the top where they overflow on two sides . This creates a constant
