How to Maintain a Dispensing Machine?
2026-08-06After a vision dispensing machine arrives,acceptance is the key step that protects equipment quality. This article walks through the acceptance process and standards — fromunpacking checks, precision tests and stability verification to software function checks
— all in one place.
1. Four Checks at Unboxing
Confirm four things on arrival:Packaging check
— is the wooden crate intact, any visible impact marks? Photograph damage before opening;Parts inventory
— check items against the contract and packing list: power cable, air hose, needle set, tool kit, manual, software USB;Appearance check
— any scratches or deformation on the body; any rust on screws and rails;Power-on test— connect power and air; confirm the machine self-checks and all axes home. Only then proceed to formal acceptance. Learn more。
installation and commissioning
2. Dispensing Precision AcceptancePrecision is the core acceptance metric.
Method: prepare test products, program and dispense per the normal process, then randomly measure 10 dispense positions with a 2D measuring projector or microscope and compare against targets. Standard: positioning accuracy ±0.5mm, repeatability ±0.02mm. Demand adjustment or replacement if out of spec.
3. Stability Verification Method98%-99.5%。
A single precision pass proves little — stability is what counts. Method: dispense 100 consecutive pieces and count yield. Standard: yield ≥98%, with attention to first-to-last variation and temperature effects. A fully warmed Boli standard machine should pass 100 consecutive pieces
| at ≥98% yield | 4. Software Function Checklist |
|---|---|
| Check Item | Acceptance Standard |
| Vision recognition | Camera images are sharp; feature points recognized accurately; offsets within 3mm auto-compensated |
| Path teaching | Supports point, line, arc and CAD import; path editing smooth without lag |
| Parameter adjustment | Pressure, speed, valve-open time adjustable in real time and effective immediately |
| Program management | Create/copy/delete/rename programs; program switching works |
| Data saving | Dispensing path screenshots can be saved and exported, with traceable query |

5. Common Acceptance PitfallsFour common traps at acceptance:
Testing only one perfect sample— a flawless demo part hides the truth; test with real production materials, not hand-picked ones;
Skipping long-run testing— signing off after a few pieces, only to see precision drift after half a day; run at least 100 consecutive pieces;
Ignoring the parts list— discovering a missing air hose or needle set after sign-off; tick every item against the packing list;maintenance and care。
6. Summary
Not arranging training— the machine arrives and nobody can run it; schedule operator training on acceptance day. Learn moreAcceptance is not a formality — it is the final safety lock on your purchase. Two things matter:
