/ What Are Boli's Core Technologies?
Daily dispensing machine maintenance is not complicated — three things: clean, check, record
. Five minutes of basic care at each shift change prevents most sudden failures.Cleaning: the needle is the worst-hit area. Dried adhesive forms hard deposits inside and outside the needle, causing uneven flow or full blockage. After use, wipe the needle exterior with a lint-free cloth and alcohol; before the next use, dispense a small amount to clear residue inside. Glue splashes on the table and rails should also be cleaned promptly — once dried they are hard and sticky, doubling cleaning difficulty. Checking: confirm the pressure gauge reads steady, the axes run without abnormal noise, and the camera view is clean.
2. Scheduled Maintenance: Service Intervals for Key Parts
Screws and rails are the core of the transmission system — re-grease every 1-2 months

Fluctuating glue volume usually means bubbles in the adhesive or a half-blocked needle. Dispense and observe; if it stays unstable, replace the needle. Off-position dots: first check that the workpiece sits square and Mark points are unobstructed, then check whether rails need grease.
Low pressure is usually falling compressor output or a leaking hose fitting — trace the air line. But two signals demand an immediate stop and a call to the vendor: metallic knocking from a motion axis (possible screw or bearing damage) and massive noise or black frames in the camera image (vision module failure). Continuing to run may cause worse knock-on damage.4. Boli's After-Sales Support SystemBoli Automation provides unlimited remote after-sales and training support for all equipment
. Day-to-day issues can be diagnosed by video call with engineers — 90% of problems are solved without an on-site visit. Hardware faults are replaced outright to keep lines running. We recommend keeping a maintenance log per machine recording service dates and replaced parts; Boli's after-sales team sends reminders for key service milestones.
The core of dispensing machine maintenance is '
clean diligently, lubricate precisely, stop on anomalies'. Five minutes of daily cleaning prevents
5. Summary
the majority of failures; key-part service intervals run monthly to quarterly. On metallic noise or vision anomalies, stop immediately — small problems become overhauls. With Boli's unlimited remote after-sales, both routine care and fault handling have a professional safety net.
