3.5.1.3 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.
②As to tape reel feeder, when ran out of one reel, operator must check whether newly changed
tape reel is correct or not.
③After 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.
⑤To check the placement position misaligned or not, component loss problem in regular work.
Find reason in time and solve it.
⑥Set 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.
3.5.2 Maintenance
Arrange regular inspection and maintenance system.
3.5.2.1 Daily Inspection
Items check
before
power on
①Temperature& Moisture: Temperature 20℃～26℃, humidity
45~70%
②Indoor environment: Air clean without aggregate air.
③No clutters within the placement area and keep rails clean.
④No spots on cameras and keep lens clean.
⑤No obstacles around the head nozzles
⑥Checking if nozzles are dirty, distorted; If so, please clean or
change the nozzle.
⑦Checking if feeders are correctly installed in stacks and confirm
no clutters on stack.
⑧Checking the connection of air connector and air hose
⑨Checking air pressure.
①Checking if the monitor display normally after system start up.
②Checking if emergency button can work normally or not.
③Checking if placement head can move back to the origin.
④Checking if there’s abnormal noise while placement head move.
⑤Checking all nozzles vacuum pressure.
⑥Checking if PCB moving on rails smoothly or not; Sensor
