How to quickly adjust the tension and feeding accuracy of Hanwha Feida? Practical tips for SMT engineers

The tension and feeding accuracy of the feeder of the surface mount technology (SMT) placement machine directly affect the quality of the placement and the efficiency of the production line. As an SMT engineer, mastering the skills of quickly adjusting the tension and feeding accuracy of the feeder can enable you to easily handle various production challenges. Especially for Hanwha Feida, although its performance is stable, actual adjustment still requires some skills. Today, I'll share some practical tips with you to help you debug quickly and avoid making mistakes.

Let's talk about "tension" first. The tension of the feeder refers to the force with which the material tape is pulled tight inside the feeder. When the tension is appropriate, the material tape can be carried steadily and the components can be placed correctly. The tension is incorrect. If the tape is too loose, it will deviate; if it is too tight, it will jam the material, seriously affecting the efficiency of surface mount technology (SMT) placement.

"Feeding accuracy" refers to the precision of the position where the material tape reaches the surface mount head. Only with precision can the surface mount head accurately grasp the components and ensure that the placement position is not deviated.

Therefore, tension and feeding accuracy form a "golden pair", neither of which can be lacking.

1. Observe the state of the material tape
   First, check if the material tape is loose or pulled too tightly. Under normal circumstances, the material tape should be smooth without bulges or pull marks.
2. Adjust the spring tension
   The tension of Hanwha SM series Feida is mainly controlled by springs. Generally, there is an adjusting screw on the side of the Feida. Tightening it clockwise increases the tension, while releasing it counterclockwise decreases it.
3. Tip: After each adjustment, manually pull the material belt to feel the force, ensuring it can be pulled without slipping.
4. Test the feeding belt
   After adjusting the tension, test the feeding belt on the machine to observe whether the feeding is smooth and if there is any material jamming.
5. Fine-tuning confirmation
   If there is any deviation or unsmooth feeding, fine-tune the spring tension according to the situation until the best state is achieved.

1. Check whether the Feida is installed properly
   When inserting the Feida chip mounter, it should be in place with a "click" sound. If it is not inserted tightly, the feeding position will be inaccurate.
2. Adjust the positioning stop plate of the Feida
   The function of the baffle is to ensure that the components remain in the correct position during feeding. Feed the material slowly in manual mode and observe whether the position of the components has shifted. If there is a deviation, adjust the position of the baffle.
3. Adjust the meshing of the feeding gear
   If the feeding gears do not mesh tightly, discontinuous feeding or belt jumping may occur. When adjusting, make sure that the gear meshes well with the material belt, but do not make it too tight to avoid damaging the material belt.
4. Use Feida test tools
   Hanwha Feida is equipped with a test bench. First, the feeding accuracy is tested on the test bench to rule out problems with the Feida itself, and then it is tested on the machine.

• The material tape has deviated
  Most likely, the tension is too loose or the baffle is not adjusted properly. Readjust the spring tension and the position of the baffle.
• "Card material"
  If the tension is too tight or the material tape is not clean, clean the feeder and appropriately relax the tension.
• The feeding is not continuous
  Check the gear meshing and confirm that the Feida is inserted in place.

• Prepare several springs and alternate the use of springs with different elastic forces to find the most suitable tension.
• Regularly clean the feeder to ensure the unobstructed feeding path.
• When operating, handle with care to avoid deformation of the feeder, which may cause inaccurate feeding.
• Conduct more tests, especially when changing the material belt or new feida. Be sure to confirm the status on the test bench first.

The tension and feeding accuracy adjustment of Hanwha Feida may seem like minor matters, but when properly adjusted, it can significantly enhance the efficiency of surface mount technology (SMT) placement and reduce downtime due to malfunctions. By mastering these practical skills, as an SMT engineer, you will definitely be able to solve problems more quickly and make production run more steadily and smoothly
