From the perspective of after-sales maintenance, these Hanwha accessories are the most prone to damage

1. Feeder: It has the highest usage rate and is also the one most prone to problems

To be honest, Feida can be said to be the most "demanding" component in a surface mount technology (SMT) placement machine.

A production line may change the material tape dozens of times a day. Feida has to constantly feed materials, withdraw the tape, position it, and precisely pick up the parts in coordination with the suction nozzle. Just think about it. With such frequent operations and sometimes the operators' improper techniques, problems will naturally arise over time.

Common faults

• The spring is fatigued and the material push is unstable
• The tape gets stuck and the feeding is not smooth
• The gears of some models of Feida wear out quickly

After-sales experience

Many of the returned flying motors are not due to quality issues, but rather the result of long-term lack of maintenance and violent operation. For instance, if workers directly "throw the flying conveyor" or "forcefully pull the material tape", it would be strange if it didn't break.

A small tip

Regularly clean the gears and check the tension of the push belt spring. Don't wait until the Feida "can't move" to think of getting it repaired.

Suction nozzle

Two. Nozzle: A small item with many problems

Don't be fooled by the small size of the suction nozzle; the accuracy of the patch placement depends on it. But it is also one of the components that are most prone to "damage" throughout the entire surface mount process.

Why?

• The suction nozzle needs to rotate frequently, move up and down, and also bear components of different weights
• Sometimes insufficient suction is due to a clogged suction nozzle, and sometimes misalignment is actually caused by worn suction nozzles

Common Questions

• The suction nozzle is damaged (especially for small materials below 0402)
• Poor vacuum, unstable suction
• The outer ring of the suction nozzle is chipped, causing the mounting position to shift

The teasing of the after-sales repairman

"Some factories use suction nozzles just like using pencil tips - they only replace them when they break, which results in a sharp increase in the defect rate of the entire line's mounting." "

A small tip

• The suction nozzle should be inspected and cleaned regularly after being used for a period of time, especially for those used to suck small materials.
• The suction nozzles wear out a lot. You can keep some commonly used models in the warehouse. Don't wait until they break down to call someone to repair them.

Iii. Motor/Servo Drive (Motor/Servo) : "Paralyzed" as soon as a problem occurs

When it comes to parts with high maintenance costs, motors and servo systems are undoubtedly the top choices.

The features of these accessories are:

• It has a relatively long lifespan in itself, but when problems occur, the impact is extremely significant
• Once the machine breaks down, it won't work and the production line must be shut down for repair
• The maintenance cycle is relatively long and the cost is not low either

Common faults

• The motor is making abnormal noises and shaking
• Encoder malfunction
• Driver board aging and overheating alarm

After-sales experience summary

Eighty percent of the problems with motors are related to unstable voltage and poor heat dissipation. Many factory buildings have outdated equipment and non-standard power distribution. An unstable voltage may burn out the servo system.

A small tip

• When installing voltage stabilizers or UPS on the equipment, especially during the hot summer period, special attention should be paid to the heat dissipation system
• If you notice shaking or abnormal speed, stop the machine immediately to check. Don't delay

Belt and synchronous pulley

Four. Belts and synchronous pulleys: They age over time. Don't neglect this

You might think that belts are "cheap and durable", but the front-line maintenance personnel will tell you: "If the belt breaks once, there won't be any output for half a day."

Main issues

• After long-term use, it ages, cracks and loosens
• It does not match the synchronous wheel and is prone to slipping
• Occasionally, there may be a "missing teeth" phenomenon, causing the components to be misaligned

Such problems do not pop up all at once but gradually affect accuracy and stability, and eventually lead to a decline in the overall line efficiency.

A small tip

• The tightness of the belt should be checked regularly. If there is any abnormal noise, deflection or wear, it should be replaced
• Maintain the synchronous pulley to prevent too much dust from getting stuck and affecting the transmission

V. Sensor: Invisible, yet influencing everything

The last "invisible killer" that many people overlook - sensors.

The photoelectric sensing, position sensing and vacuum sensing inside the surface mount technology (SMT) machine all rely on them. Once a sensor malfunctions, various inexplicable malfunctions will occur, such as:

• The error message is inaccurate
• Feida was clearly installed but the police were called
• The suction nozzle grabbed the component system but considered it "not sucked".

Common after-sales scenarios

The customer insisted that there was a problem with the software, but after checking for a long time, it turned out that the position sensor was covered with dust.

A small tip

• Regularly clean the sensor head, especially the areas near the feeder and the suction nozzle. If the alarm is frequent but there is no obvious fault in the system, the sensor should be inspected first.
