Maintenance

5.4.1 Take effective measures to reduce/ avoid malfunction

(1)

Reinforce daily maintenance

(2)

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.

(3)

Requirements for operator

(4)

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.

(5)

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.

(6)

Operator should be concentrated.

(7)

Observation-- to see whether there is abnormal situation, such as peel-box doesn’t work, plastic

tape is broken etc.

(8)

Listening-- whether have strange sound, such as noise from placement head, sound of loss

component, strange noise of conveyor etc.

(9)

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.

(10)

The most easily appeared problem during work are placement wrong components and

placement misaligned. Supply below measures for ref.

(11)

It needs to check whether the components’ package is matched with related feeder. If not,

please correct them.

(12)

As to tape reel feeder, when ran out of one reel, operator must check whether newly changed

tape reel is correct or not.

(13)

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.

(14)

Operator must check the first finished PCB of each file. If any problem, please find solutions

such as revise program to solve it.

(15)

To check the placement position misaligned or not, component loss problem in regular work.

Find reason in time and solve it.

(16)

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.

5.4.2 Maintenance of device

Check below points daily

(1)

Please check below before turn on the machine

a. Temperature and humidity: temperature range 20℃～26℃, humidity range 45～70％.

b. Working environment: please keep air fresh to avoid corrosive air in.

c. Make sure there’s no obstacle on dual rails or the whole working area.

d. Make sure camera lens is clean, no dirty things.

e. Make sure no obstacles around the head nozzles.

f. Please check whether nozzle is dirty or out of shape and adopt relevant cleaning measure or

change new nozzle.

g. Please check whether feeders are well installed, and keep feeders clean.

h. Please check whether the air hose is well connected with machine.

(2)

Please check listed below after turn on the machine.

Error tips will show on the monitor if the machine work abnormality.

a. Check the monitor screen whether display normally after system starting working. Check

emergency switch whether could work normal.

b. Check the placement head whether could return to the original place.

c. Whether have abnormal noise when placement head move.

d. Check negative pressure whether in normal range or not.

e.by the way checking PCB’s transmission on dual rails to know whether sensor is still work fine.

Check below points monthly

a. X, Y axis--please make sure no abnormal noise when placement head move.

b. X, Y motor--please make sure motors working well, no abnormal heating appearance.

c. Nozzle--please check nozzle whether up down flexibly, not bent, check the suck surface whether

level.

d. Air hose--check the air hose and connector, make sure hose is fine without broken, abrasion or

air-leak etc.

e. Negative pressure--check all nozzles’ negative pressure. If abnormal, please clean nozzles.

f. Positive pressure--check whether they’re normal.

g. Optical axis--please check whether it is covered dusk. Please keep it clean and lubricated.

h. Operation button--check each button to make sure they are well-worked

i. Connector--check if well-connected of the air connector and air hose.
