The placing head is a critical component of the Fuji NXT placement machine. Due to improper operations, crashes frequently occur, leading to significant maintenance costs. To help mitigate these issues, we have compiled several methods from years of experience to reduce the likelihood of such incidents.
01 / Misplaced Scrap Boxes
Issue: First-generation scrap boxes lack sensors. If not placed correctly after removal, they can cause crashes.
Solution: For first-generation boxes, ensure correct placement. Second-generation boxes have sensors to avoid such issues. Additionally, modifying the scrap box to reduce its height can minimize collision chances.
02 / Tape Feed Collision
Issue: Tapes sticking out or being pulled quickly from feeders can cause the tape to lift and hit the placing head.
Solution: Regularly train and emphasize proper handling to operators. Implementing strict operational protocols can mitigate this risk.
03 / Incorrect Feeder Handling During Production
Issue: Handling feeders while the machine is running can cause the placing head to collide with tapes and feeders.
Solution: Ensure the machine is stopped before handling feeders. Adjust the height of feeder cover caps to avoid collision risks, especially with M6 and certain versions of M3 modules.
04 /Nozzle changing Issues
Issue: When nozzles get stuck during line changeovers, improper checking can damage the placing head.
Solution: Carefully check and maintain nozzle seats regularly. Software improvements in newer versions help mitigate this risk.
05 /Storing Unused Feeders on Empty Slots
Issue: Incorrectly placed feeders on empty slots can collide with the placing head during operations.
Solution: Ensure correct placement and adjustment of feeder cover caps to prevent collisions.
06 /Dropping the Placing Head During Line Changes
Issue: Mishandling the placing head can cause it to fall and crash.
Solution: Handle with care and ensure proper grip during line changes to avoid such accidents.
07 /Track Collision During Head Change
Issue: The placing head can collide with the track if not handled properly during head changes.
Solution: Adjust the track to its maximum width in newer versions (V4.42 and later) and handle with appropriate force to avoid collisions.
08 /Improper Maintenance and Installation
Issue: Incorrectly fixed placing heads or using adhesive tapes on sensors can cause loosening and collisions during movement.
Solution: Train technicians to avoid using adhesive tapes and ensure proper fixation of placing heads.
09 /Tools Left Inside the Machine After Repair
Issue: Tools or screws left inside the machine can cause collisions.
Solution: Always double-check and remove any tools or screws after repairs to prevent such incidents.
10 /Dropping Large Components
Issue: Heavy components or specialized nozzles can fall and cause crashes.
Solution: Pay close attention to program settings and select the appropriate nozzles to avoid such collisions.
