12.1.2 Requirements for operator
● Operator should get a basic operator training, which should cover fully all the skills and knowledge needed to safely
operate the type of pick and place machine.
● Operating strictly against equipment's instruction. Don’t use machine with problems. Stop the machine once malfunction
appears and contact with the after-sales service staff, restart to work after problem solved.
● Operator should be concentrated.
Observation-- to see whether there is abnormal situation, such as peel-box doesn’t work, plastic tape is broken etc.
Listening-- whether have strange sound, such as noise from placement head, sound of loss component, strange noise of
conveyor etc.
Handwork-- solve some small problems in time, such as install feeder, correction placement position etc. If the main
machine body or circuit problem, please consult after-sales staff. Formulate measures to reduce/ avoid big problem.
12.1.3 Formulate the measures to reduce/avoid big problem
The most easily appeared problem during work are placement wrong components and placement misaligned. Supply below
measures for ref.
①
It needs to check whether the components package is matched with related feeder. If not, please correct them.
②
As to tape reel feeder, when ran out of one reel, operator must check whether newly changed tape reel is correct or not.
③
After import the SMD file or edit chip list manually, please recheck each components No., nozzle rotation angle and
placement position to make sure correct.
④
Operator must check the first finished PCB of each file. If any problem, please find solutions such as revise program to
solve it.
⑤
To check the placement position misaligned or not, component loss problem in regular work. Find reason in time and
solve it.
⑥
Set pre-welding detection station (manual or AOI)
In sum, P&P machine's running speed and placement accuracy still has limit. Peoples work is important to run machine on
its proper role. So, it’s necessary to comply with effective measures to keep machine normal work, its placement quality and
efficiency.
