Detailed Explanation of Fault Diagnosis and Maintenance Steps for Hanwha Chip Mounter feeders

Having worked in the SMT industry for a long time, everyone knows that the Feeder of the surface mount technology (SMT) placement machine is no small player. Although it is just a component responsible for "feeding materials", if it malfunctions, the entire production line will be like a truck with a throat stuck, unable to move smoothly anywhere.

Especially for Hanwha's surface mount technology (SMT) machines, there are many types of Feida and they have a high degree of automation. However, once a problem occurs, it can be a bit difficult to troubleshoot. So, what are the common faults of Hanwha's surface mount technology (SMT) machine feeder? How to check step by step and how to fix it?

We won't go through textbook-style explanations. Instead, we'll go through a practical process so that you can apply what you've seen and do on the spot.

Let's first quickly review the functions of Feida:

In simple terms, it is the "feeder" of the surface mount technology (SMT) machine.

There are so many small components on the PCB board. To attach them one by one quickly and accurately, it relies on Feida to precisely deliver the materials under the suction nozzle. If a feeder makes a slight mistake, the suction nozzle may be crooked, fail to suck, or even suck wrongly.

Several common faults of the feeder in a surface mount technology (SMT) placement machine

Let's first take a look at what the most common faults of the feeder on the production line are:

1. No material flow/The feeding is not smooth

   One of the most common problems. If the Feida motor does not move, gets stuck with materials, the spring ages, or even has foreign objects on the guide rail, it can all lead to "inability to push".

2. Over-feeding/feeding position skipping

   If the material belt jumps over several positions at once, it is mostly due to the slippage of the feeder gear or the malfunction of the photoelectric sensor.

3. The material tape breaks or gets stuck

   This is related to tension control. Sometimes the Feida tensioner is too tight, or the quality of the material tape itself is poor.

4. Report Feida error codes (such as E1, E3, E5, etc.)

   This type of malfunction is usually caused by the system detecting abnormal signals, such as poor power contact, inaccurate encoder feedback, or even improper insertion of the feeder slot.

Next, let's get to the point. How to check step by step if there's a problem

1. Step 1: Check the prompt and lock the range

   Hanwha's surface mount technology (SMT) machine will directly report an Error, such as "Feeder Error E1" or "Feeder not detected". At this point, the first step is to check the content of the error report to initially determine which feeder has a problem. Is it a mechanical jamming? Or is there a signal loss?

2. Step 2: Physical inspection of the Feida body

   Disassemble the faulty feeder and visually inspect it to see if there is any deformation, breakage or any debris blocking the feeding port. Sometimes it's just a small piece of paper stuck in the gear.

3. Step 3: Inspect the feida interface and contact points

   Most Hanwha Feida models use electric feida, and the metal contacts at the bottom of the feida are the key. If the contact is poor, it will lead to abnormal recognition or failure. You can gently wipe the contacts with an eraser and then insert them back to try.

4. Step 4: On-machine test

   After checking that there are no issues, reinsert the feeder and jog the "feeding" function on the machine to observe if the material flows smoothly. If the material leakage is still incorrect, you can proceed to the next step - module-level maintenance.

Feida maintenance tips and practical suggestions

When repairing a flying motor, in fact, it is often not a "major overhaul", but rather a partial adjustment and replacement.

1. Replace small parts such as springs, pressure plates and gears

   Many problems with Hanwha Feida lie in these vulnerable parts. Generally, manufacturers have separate repair kits, and you can solve the problem by replacing them yourself.

2. Pay attention to lubrication and cleaning

   After long-term use, the track of the Feida will accumulate dust and the resistance will increase. Gently wipe the tracks and gears with an alcohol cotton cloth. Add some lubricating oil if necessary, but don't use too much to prevent it from overflowing.

3. Standardized maintenance procedures

   If it is a batch delivery issue, it is recommended to establish a small process, such as unified maintenance, cleaning, and number management every week. This will be more efficient and also facilitate subsequent troubleshooting.

Apart from maintenance, procurement is also very important

Many small factories, in order to save costs, like to purchase "third-party Feida", but the result is poor stability, frequent breakdowns and frequent repairs. Over time, they are actually more expensive than the original ones.

It is recommended to either choose reliable third-party manufacturers (with a good reputation) or directly use original factory parts. Moreover, Feida is a "frequently used component". When buying a second-hand one, be sure to pay attention to the maintenance record. Don't be tempted by low prices and end up in a trap.

Only by understanding Feida can the production line not fail

The Feida of Hanwha's surface mount technology (SMT) machine is neither too big nor too small. Once it goes on strike, the overall production efficiency drops.

So, rather than waiting for it to break down before repairing, it's better to maintain it more often and conduct regular inspections on a regular basis. Once you master the basic troubleshooting methods, many problems can actually be solved within five minutes, and there's no need to wait for an engineer to come.

If you are an operator, an engineer, or even a boss, remember this: Although Feida is small, its role is significant. Don't let it become a "weak link in the production line".

If you find this article practical, you are also welcome to save it, share it or show it to your colleagues in the workshop. Maybe one day it will come in handy for "putting out a fire"!
