Maintenance Of Pick And Place Machine - Industrial News

I. Take effective measures to reduce /avoid malfunction

1. Reinforce daily maintenance

Pick and place 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

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.

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.

It needs to check whether the components package is matched with related feeder.
As to tape reel feeder, when ran out of one reel, operator must check whether newly changed tape reel is correct or not.
After programming, operator must double check the component number, placement position, and angle are correct for each placement step.
Operator must check the first finished PCB of each file. If any problem, please find solutions such as revise program to solve it.
To check the placement position misaligned or not, component loss problem in regular work. Find reason in time and solve it.
Set pre-welding detection station (manual or AOI)

In sum, SMT 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.

II. Device Maintenance

Arrange regular inspection and maintenance system.

1. Daily Inspection

Items

Items check before power on

① Temperature& Moisture: Temperature 20℃～26℃, humidity 45~70%

② Indoor environment: Air clean without aggregate air.

③ No clutters within the placement area and keep rails clean.

④ No spots on cameras and keep lens clean.

⑤ No obstacles around the head nozzles

⑥ Checking if nozzles are dirty, distorted; If so, please clean or change the nozzle.

⑦ Checking if feeders are correctly installed in stacks and confirm no clutters on stack.

⑧ Checking the connection of air connector and air hose

⑨ Checking air pressure.

Items check after power on

① Checking if the monitor display normally after system start up.

② Checking if emergency button can work normally or not.

③ Checking if placement head can move back to the origin.

④ Checking if there's abnormal noise while placement head move.

⑤ Checking all nozzles vacuum pressure.

⑥ Checking if PCB moving on rails smoothly or not; Sensor workable or not.

⑦ Checking if the board has been well fixed by magnetic bar and pins.

2. Monthly Inspection

Items	Detailed Inspection
X/Y axis	Make sure no abnormal noise while placement head moving.
X/Y motor	Make sure X/Y motors no overheating.
Nozzle	Checking if all nozzles are good without bend and nozzle surface is horizontal.
Air hose	Checking the connection between air hose and machine, keep sure the hose in good situation without wearing or air leaking.
Step motor	Checking if any dirty on step motor, synchronous belt, Synchronous wheel. Make sure the Z-axis motor can up, down and rotate smoothly.
Z-axis motor	Checking if the placement head can go up and down smoothly. Use your finger to push the nozzle to check if it moves smoothly. Let each nozzle head up and down beyond the normal range.
Vacuum pressure	Checking all nozzles' vacuum pressure. If abnormal, please clean nozzles.
Positive pressure	Checking if the positive pressure normal.
Optical axis	Checking whether it is covered dusk. Please keep it clean and lubricated.
Operation button	Checking each button to make sure they are well-worked.
Connector	Checking if well-connected the air hose and air connector.
PCB clamp block	check their wear pattern.
