5.2. Maintenance
5.2.1.Take effective measures to reduce/ avoid malfunction
1. reinforce daily maintenance
P&P machine is that high-accuracy device which requires a clean working environment with
constant temperature and humidity, so it’s necessary to have a routine maintenance.
2. Requirements for operator
(1)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.
(2)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.
(3)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.
3.Formulate 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 need 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 component’s 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)In sum,P&P machine’s running speed and placement accuracy still has limit. People’s 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.
