How to establish a maintenance and repair system for Hanwha's surface mount technology (SMT) placement machines?

To be honest, no matter how stable the performance and high the efficiency of Hanwha's surface mount technology (SMT) machines are, if there is no reliable maintenance and upkeep system, problems will keep recurring like a "cold" after a year or two of use, affecting the production rhythm and causing both distress and cost.

Then what should we do? In fact, establishing a practical, efficient and easy-to-implement maintenance and repair system is not complicated. As long as your thinking is clear, the system is in place and the personnel keep up, you can basically make the equipment "less prone to illness and less downtime". Today, let's talk about how to gradually set up the maintenance and upkeep system for Hanwha's surface mount technology (SMT) placement machines.

Many factories have a common problem: equipment is not repaired until it breaks down, and problems are dealt with only when they arise.

It sounds like it saves labor and costs, but in fact, it's "saving a little money but losing a lot". For high-speed equipment like surface mount technology (SMT) placement machines, with precise components and high operational intensity, the most feared thing is getting sick from overwork. So the first step - establish a preventive maintenance awareness!

That is to say, it is not about repairing only when problems arise, but rather maintaining it periodically and in a planned manner, such as:

• Wipe the suction nozzle and check the tightness of the feeder every day.
• Clean the tracks and lubricate the X/Y axis slides every week.
• Check the airway system and camera focal length every month.
• Test the performance of vacuum pumps, motors, etc. every quarter.

Discovering minor problems in advance can prevent the equipment from suddenly "breaking down".

When it comes to maintenance and repair, the most dreaded thing is that no one is in charge and the management is unclear. You need to have a "checklist" system, clearly stating the maintenance content, frequency, time and person in charge.

For example:

In this way, if any problem occurs, it can be traced quickly. Who is responsible, at which stage, and at which time are all clear and transparent.

A good maintenance system should be "three-level classification with clear division of labor" :

1. First-level maintenance: Handled by the operator themselves

For instance, if the suction nozzle is clogged, the feeder is loose, or there is dust on the track, none of these require mechanical repair. The operator can handle them on the spot by themselves.

2. Secondary maintenance: Equipment engineers get involved

For instance, issues such as abnormal XYZ axes, image recognition offset, and unstable air pressure, which involve hardware parameter adjustment or software calibration, require experienced technicians to operate.

3. Level 3 maintenance: Manufacturer support or professional outsourcing

For instance, major issues such as main control board failure, software system crash, and spindle motor burnout should be handled by Hanwha's original factory or authorized service personnel.

This division of labor can not only enhance efficiency but also reduce the risk of human error.

Some components of the surface mount technology (SMT) machine are high-frequency wear parts, such as nozzles, belts, air pipes, photoelectric sensors, and Feida springs. It is best to keep a batch of inventory on site.

You can make a "Key Accessories Inventory list" following the following ideas:

• Which ones are frequently replaced?
• What is the normal lifespan?
• Is the price cheap and easy to buy?
• Are there any domestic alternative parts available for selection?

If you prepare it in advance, you can deal with it immediately when there is a problem with the equipment, without wasting time or delaying the delivery.

Many devices break down. It's not a problem with the devices themselves, but because people don't know how to use or maintain them.

Therefore, the factory must conduct regular technical training to ensure that both operators and mechanics are aware of

• How should a surface mount technology (SMT) placement machine be maintained?
• When should it be reported for repair?
• In what situations can one handle things by oneself and in what situations should one not act randomly?

At the same time, records should be made for each maintenance and repair, clearly stating the time, problem, handling process and the person handling it. Don't be afraid of the trouble. These data are very useful for analyzing problems and optimizing maintenance strategies in the later stage.

In addition to regular maintenance, it is recommended to conduct a monthly equipment inspection and a "comprehensive physical examination" once a year.

Inspection can be led by the equipment supervisor or the technical department, with random checks on the operating status of the equipment.

For annual inspection, it is recommended to cooperate with Hanwha's original factory or service provider to conduct in-depth maintenance such as complete machine testing, motherboard inspection, and electrical system inspection.

This is just like a person having a regular physical examination. It's best if there are no problems, and if there are, they should be detected early.

The final sentence summary: The surface mount technology (SMT) machine is not "repaired when broken", but "run after being well maintained". Hanwha's surface mount technology (SMT) machines are so advanced. If we can establish a complete maintenance and upkeep system, it will not only reduce the failure rate but also extend the service life and improve production efficiency.

Don't wait until the machine "throws a tantrum" to panic. From today on, establish a maintenance system, improve it step by step and stick to it. You will find that the equipment is even more worry-free than people!
