A Comprehensive Guide to the Top Ten Common Faults and Solutions of Samsung Surface Mount Technology (Practical Edition)

Components fail to be sucked up or fall off after being sucked up. Flying parts and lost parts occur from time to time.

Check if the suction nozzle is clogged or damaged. It can be disassembled and cleaned with alcohol.

Check if the negative pressure is normal. Sometimes, problems with the vacuum generator can also affect the suction force.

If the suction nozzle returns to normal after replacement, it is basically due to aging or damage of the suction nozzle.

Regularly maintain the suction nozzle and replace the aged parts on time. When the suction force is unstable, first check the vacuum system and sensor.

The machine prompts errors such as "Recognition failed" and "Component positioning error".

Check if there is any dust or stains on the lens and gently wipe it with lens paper.

Whether the light brightness is appropriate or not, the reflective element sometimes needs to adjust the lighting Angle.

Check whether the component image library in the mounting program is correct and whether the components have been updated but the parameters have not been changed.

Before starting up every day, check the visual system, maintain the lens and lighting, and adjust the image template in a timely manner according to the BOM.

Material jamming, inability to deliver, skipping steps, misalignment, etc.

Check if the Feida itself has any mechanical damage and if the retaining rings and gears are worn.

Clean the feeder track. Sometimes, the accumulation of dust and impurities can cause feeding to be stuck.

Check if the lock position of Feida is tightly fastened. Looseness will affect the accuracy of feeding.

Feida needs regular maintenance. When changing the material tape, handle it gently and avoid pulling it hard.

The mounting position is offset, and the deviation varies for different boards.

First, check the fixture and guide rail to see if they are loose.

Check whether there is any recognition deviation in the MARK points identified on the PCB.

If it is a multi-segment board or a double track, it is necessary to check whether the track synchronization is consistent.

For friends who often run multiple panel assemblies, it is recommended to do MARK calibration and fixture adjustment once a week.

While pasting, it suddenly stopped and reported an error. After restarting, it could resume.

Take a look at the error codes. Most of them are communication failures or sensor abnormalities.

Focus on inspecting the I/O modules and control systems, especially the cable connection points.

Excessively high or low temperature and humidity can also cause abnormalities. Don't ignore the workshop environment.

Regularly carry out system maintenance, wipe the connection line interfaces with alcohol, and do a good job in anti-static and temperature and humidity control.

The large deviation of the mounting position affects the welding quality.

Check if it is a mechanical coordinate deviation and inspect the mechanical origin.

Check whether the bottom of the machine is placed flat and if there is any vibration.

Check whether the placement height setting is correct, especially for components of different thicknesses.

Recalibrate the coordinate system. The key is not to skip the steps of startup calibration, and do not neglect shock and tilt prevention either.

During operation, the noise becomes abnormal, like a "creaking" or "whistling" sound.

Check if the mechanical guide rails are short of oil.

Check whether the bearings and drive belts are worn.

Check the rotating parts of the fan and motor.

Lubricate the guide rails and lead screws at least once a month. Check for any abnormal sounds immediately; otherwise, serious problems may occur.

The operating system lags, the touch screen response is slow, and sometimes it freezes.

Check whether the memory and hard disk of the industrial control computer are full.

Check for viruses or program conflicts.

Check if the voltage is stable and if there is any problem with the UPS power supply.

The system should clean up junk files and temporary files every six months. Don't store the hard disk too full.

When the Feida is plugged in, the system either fails to recognize it or recognizes it incorrectly.

Check whether the Feida label chip is loose or damaged.

Check if the feida trough is dirty or oxidized.

Replace it with a normal Feida and test it to see if it's a problem with the Feida itself.

When plugging or unplugging the Feida, do it gently and avoid violent operation. Feida chips have electrostatic protection requirements. Pay attention to discharge.

It often reports "abnormal vacuum" or "low negative pressure".

Check whether the negative pressure generator is damaged.

Check whether the suction nozzle and the suction pipe are leaking.

Check if the vacuum sensor is functioning properly.

Regularly test the negative pressure value. If there is a problem, replace the sensor and pipeline first and observe the response.
