BL18 Screw Fastening Machine Video Guide: 19 Step-by-Step Tutorials

BL18 Screw Fastening Machine — Written Step-by-Step Guide

The same 19 videos as text, grouped into the four phases an operator actually works through. Use this section at the machine when you do not want to scrub a video.

Phase 1 — Get it running (Steps 1–3 = Part 0–2)

1. Power and language — Switch the main breaker on, then use the pendant menu to set the interface to English (or 中文). Press reset to clear the alarm that appears after a language change — this is normal, not a fault.
2. Know the two fixtures — The machine fastens on one fixture while the other is loaded. Fixture 1 and Fixture 2 each carry their own coordinate set, so a cabinet type is a program, not a re-teach.
3. Understand the coordinate screen — X/Y/Z positions are written and confirmed on the pendant; the yellow cursor marks the parameter being edited. Nothing is saved until you confirm the coordinate.

Phase 2 — Teach the cabinet (Steps 4–8 = Part 3–7)

1. Clear the red default parameters — Factory defaults arrive marked in red and some servo options are missing. Delete the red set and restore the defaults before teaching anything.
2. Record every screw hole — Move the head to each screw hole on Fixture 1 and store the coordinate. This is the step that decides whether the rest of the program is right — one missed hole is one cabinet with a loose screw.
3. Set the Z-axis fastening height — Approach at medium speed, bring the bit to the hole centre, then set the height so the screw seats without the panel flexing (steps 6 and 7 do this twice — once as a setting, once as a single-step test).
4. Test on a real cabinet — Run the program on an LED module cabinet before production. Confirm every screw is seated and that the cabinet is clamped flat.

Phase 3 — Run and recover (Steps 9–13 = Part 8–12)

1. Learn the cycle — Fixture seated, module orientation checked, obstacles cleared, fasten, unload — the machine repeats this cycle, so anything that breaks it is either the program or the screw path.
2. Feeder stopped? Step 11 — Open the lid, look at the track for a jam, adjust the track height and restart. Do not change parameters before checking the track.
3. Screw blown in tilted? Step 12 — Lower the nozzle to adjust the position using Preview Trajectory, then check the cylinder actions against the indicator lights.
4. Worn nozzle? Step 13 — Replace the nozzle, raise it clear for safety, then re-align the camera red cursor before running.

Phase 4 — Setup, calibration and maintenance (Steps 14–19 = Part 13–18)

1. Remove interference before a job — Step 14 shows which parts must come off to avoid a collision — and where they go back.
2. Calibrate the camera — Step 15 is the full calibration; do it after any nozzle change, any camera work, or if screws start landing consistently off-centre.
3. Set torque and detection — Step 16 sets fastening torque, detection thresholds and safety parameters. Torque is a setting, not a feel — this is what makes every screw identical.
4. Program the second fixture — Step 17 switches left/right and gives each fixture its positions, which is what allows two different cabinets at once.
5. Pickup height and first driven screw — Step 18 sets pickup height so the screw is held properly, then drives one screw before automatic run.
6. Daily and weekly routine — Step 19 covers operation, finishing a partly assembled cabinet from a later position, and the lubrication and wipe-down that keeps the head accurate.

What each video covers

• 1. Machine overview and how to switch the interface language. Watch first if the teach pendant is not in your language: switching EN/中文, clearing the alarm with the reset key, and the menu layout you will use for every job.
• 2. LED display cabinet assembly machine — screw fastening automation overview. What the machine does on a real cabinet, and how the two fixtures relate to one fastening head.
• 3. Power-on sequence, screen basics and coordinate system. Where the main switch is, what the start screen shows, and how the X/Y/Z coordinates are written and confirmed.
• 4. parameter defaults and servo configuration. What the red default parameters mean, why some servo options are missing, and how to restore the factory defaults.
• 5. Recording screw-hole coordinates on Fixture 1. Teaching the screw positions on the first fixture, one hole at a time, and confirming each stored coordinate.
• 6. Setting the Z-axis fastening height. How to bring the head down to the cabinet, set the fastening height at medium speed, and check the bit sits in the screw hole centre.
• 7. Z-axis height and single-step fastening test. The same height procedure repeated with the single-step test, plus the points to watch before you trust a program.
• 8. Screw assembly test on an LED module cabinet. Running the program on a real module cabinet to confirm every screw is seated before production.
• 9. How a full machine cycle works. The workflow cycle: Fixture 1 recognised by the machine, module orientation checked, obstacles cleared, fastening, unload.
• 10. Screw feeder and air supply system. The feeder, the air inlet and the branch that feeds the fastening head — what has to be connected before the first run.
• 11. Screw feeder jam fix. The single most common stoppage: open the lid, check the track, adjust the height, clear the jam and restart.
• 12. Nozzle adjustment when a screw is blown in tilted. Preview trajectory, bring the nozzle down, correct the position, and the cylinder actions to check with the indicator lights.
• 13. Nozzle replacement and camera cursor. Replacing a worn nozzle, lifting it clear, then aligning the camera red cursor so pickup lands in the right place.
• 14. Setup and safety checks. Removing the interfering parts before a job so the head cannot collide, and where each part has to go back.
• 15. Vision camera calibration. The full camera calibration: screen reflection check, then the distance calibration that keeps ±0.02mm repeatable.
• 16. Torque, detection and safety parameters. Setting fastening torque, the detection thresholds and the safety parameters, then confirming them on a test screw.
• 17. Programming a dual-fixture machine. Switching between left and right fixtures, the three fixture parameters, and how each fixture gets its own positions.
• 18. Pickup height and screw driving test. Setting the pickup height so the screw is held properly, then driving one screw and starting automatic run.
• 19. Operation and maintenance. Daily operation, finishing a partly completed cabinet from a later position, and the lubrication and wipe-down routine.
