In the electronics manufacturing industry, the placement machine is a commonly used device for accurately mounting electronic components on the PCB.
In order to ensure the normal operation of the placement machine and prolong its service life, regular maintenance is essential. The following are some methods
and techniques for placement machine maintenance to ensure its efficient and stable work.
1. Regular cleaning: Regular cleaning is a key step in maintaining the placement machine
First, turn off the placement machine and disconnect the power. Use stencil wiping paper and non-corrosive cleaning agent to gently wipe the surface of the machine,
especially the surface of the X/Y cantilever magnetic track, the grating ruler, and the PCB processing area. At the same time, make sure to clean the dust and debris inside
the machine, and use a vacuum cleaner to clean the residual materials on the track and jacking platform.
2. Lubricating parts
placement machine is a kind of high-precision equipment. In order to ensure its normal operation and prolong its service life, regular lubrication is a crucial maintenance task.
When choosing a suitable lubricant, it is necessary to ensure that the lubricant has good anti-wear and high temperature resistance properties to adapt to the working environment
of the placement machine. Common lubricants include grease and oil, and appropriate lubricants can also be used according to the placement machine manufacturer's
recommendations. The oiling of the conveying guideway is smeared, and the slider of the X/Y cantilever is oiled. After the oiling process is completed, the equipment needs to carry
out the test of "permanent operation of the cantilever". The recommended duration is about 30 minutes. It should be noted that excessive lubrication should be avoided, so as not to cause unnecessary failures.
3. Check the track light barrier sensor
The light barrier sensor on the track of the placement machine plays an important role in the accurate positioning and detection of the PCB. Regularly check the working condition
of these parts to ensure they are clean and properly aligned. If damaged or invalid parts are found, replace them in time.
4. Calibration and adjustment
The accuracy and stability of the placement machine requires regular calibration (ACT, MAPPING board) using a unique jig. Carry out regular calibration and calibration according
to the manufacturer's instructions. These include the calibration of the patch head (ACT) and the calibration of the X/Y axis cantilever (MAPPING). ACT feeds back the overall mounting
accuracy of the placement head, and MAPPING feeds back the slider accuracy of the X/Y axis (mounting influence characteristics: in a certain axis direction, the overall offset). In order
to ensure the authenticity of the calibration process, it should be carried out by professionals to ensure the placement accuracy and stability of the placement machine.
5. Check the power supply and electrical connections
Regularly check the reliability of the electrical connection of the placement machine to ensure the stability and safety of the equipment. Check whether the power supply line is
damaged or exposed copper, loose, and check whether the electrical connection is firm. If any problems are found, repair or replace them in time.
6. Update software and firmware
The software and firmware of the pick and place machine are the key to its proper operation. Regularly update software and firmware versions to ensure that the software functions of the
machine are more perfect and there are fewer BUGs. In addition, it is necessary to regularly back up the mounter data (MA) to the server to prevent data loss. In addition, when the system
is abnormal, it can also solve the abnormality by quickly restoring the data of the placement machine.
7. Training operators
In addition to regular maintenance work, training operators is also an important part of maintaining the normal operation of placement machines. Make sure the operator is familiar
with the correct operation of the placement machine and the handling of common faults to reduce unnecessary machine damage and downtime.
In short, the maintenance of placement machine is the key to ensure its efficient and stable work. By regularly cleaning, lubricating, calibrating and adjusting, checking power
and electrical connections, updating software and firmware, and training operators, you can prolong the service life of placement machines and improve production efficiency.
