For non-contact dispensing in automated industrial production processes LIQUIDYN developed and offers a series of electro-pneumaticly actuated micro dispensing valves, which have been proven in many applications. These valves are equipped with a high dynamic actuator system, which enables switching times of less then one millisecond. During conception of these valves high attention was given to standardised interfaces, For this reason the electro-pneumatic switching valve, which operates on a 24V DC-power supply, (a voltage which is available in most industrial SPS-process controls) is utilized for the actuator system. Furtheron the micro dispensing system is designed for simple operation and even cleaning and maintenance of the fluidic components can be performed by the customer.
By sacrificing a piezo-electrical actuator system in favour of an electro-pneumatical drive system, the following advantages result:
– Inactive state, normaly closed (NC)
– High safety (low voltage in the handling area)
– Simple maintenance by the customer
– Simple nozzle change (within seconds)
– No readjustment after cleaning/nozzle change
– High reliability, low failure rate
– Insensitive to environmental conditions (shock and moisture)
– High life time
– Low cost control technique
– Low cost maintenance
Examples for Application:
Saving of an additional cleaning process after soldering, through optimising the amount of soldering flux.
Selective bonding of electronic components
Application of instant glue in a 0.4 mm wide groove
Application of electricly-conductive silver-adhesive
Joining of shaft and hub with an anaerobic-adhesive
Defined deposition of amount of silicon-oil on medical components
