What Is Special About a Dispensing Machine's Frame Structure

1. Why a Vision Dispensing Machine Needs Compressed AirThe dispensing drive comes from。pneumatic power— the piston inside the glue valve is pushed by compressed air, and air pressure sets flow rate and speedVision positioning system: place workpieces freely — the machine photographs and recognizes the LOGO groove contour and auto-corrects; slight tilting never misses the mark; quick changeover across models。
. The valve's closing suck-back also relies on air. Beyond the dispensing valve, fixture cylinders and cleaning air-blasts need supply too. So the compressor is not optional — it is a required peripheral. Learn more
2. Three Core Compressor Selection ParametersFirst, discharge pressure0.4-0.6MPa. The machine's standard working pressure is0.7-0.8MPa0.4-0.6MPa
; the compressor's rated discharge should reach0.7-0.8MPaWhat Is the Motion Control Card in a Vision Dispensing Machine?。
, leaving headroom for line loss and fluctuation. Below 0.4MPa gives weak, intermittent dispensing; above 0.8MPa can damage valve seals.Second, air volume. A single machine consumes about 30-50L/min; a small compressor rated above 100L/min suffices. With several machines sharing supply, add per machine plus 30% headroom. Learn more。
Third, air cleanliness
. Compressed air must be free of water and oil, or it corrodes valve internals and contaminates adhesive. Always fit an
oil-water separator and drying filter
3. Silent Oil-Free Compressors Are the First ChoiceWorkshops care about noise: traditional piston compressors run 75-85 dB, wearing on operators over long shifts. Silent oil-free compressors stay below 60 dB and deliver oil-free air — no extra oil filter needed. Boli recommends pairing machines with silent oil-free scroll compressors: a 150L/min unit costs about 2,000-4,000 RMB and comfortably supports 1-2 dispensing machines. If your plant has a central air station, just add a precision filter at the machine — no separate compressor needed.4. Air Line Connection Notes
5. Summary
Use PU pneumatic hose of 8mm ID between compressor and machine. Beyond 5 meters of run, step up to 10mm to avoid pressure droop. Install apressure-regulating valve
