Reasons and Countermeasures for Material Overflow During SMT Soldering Production

Many users of SMT surface mount machines have noticed that during the production process of SMT surface mounting, there is a phenomenon of material spillage. This not only leads to material waste but also affects production efficiency.

Below, Yinsaite will discuss in depth the reasons for material spillage in SMT surface mount machines and propose corresponding solutions for the causes and countermeasures of material spillage in SMT surface mount machines. Interested friends, come and have a look!

Nozzle issue: If the nozzle becomes deformed, clogged or damaged, it will result in insufficient air pressure, preventing it from properly suctioning the components.

Solution: Regularly clean and inspect the suction nozzle, replace the damaged suction nozzles in time, and ensure that the suction nozzle is in good condition.

Identification system issues: Poor vision, lens contamination, and improper light source settings can all affect the identification outcome.

Solution: Keep the surface of the recognition system clean, regularly adjust the intensity and grayscale of the light source, and ensure that the recognition system can accurately identify the components.

Inaccurate material extraction position and improper material extraction height: Solution: Adjust the material extraction position to ensure it is at the center of the component, and set an appropriate material extraction height to prevent deviation and incorrect extraction.

Vacuum pressure issue: Insufficient air pressure or blockage of the vacuum channel can lead to failure in material extraction.

Solution: Regularly inspect the gas pressure pipeline, repair any leaking sections, and ensure stable gas pressure and compliance with equipment requirements.

Program issue: The component parameters set in the edited program are incorrect. They do not match the dimensions and brightness of the incoming materials, resulting in the program failing the identification and being discarded.

Solution: Adjust the component parameters and search for the optimal parameter settings for the components.

The problem with the incoming materials: The materials are irregular in shape, and they are defective products such as those with oxide on the pins.

Solution: The IQC should conduct incoming material inspections and contact the component suppliers.

Feeder problem: The position of the feeder is deformed, resulting in poor feeding: the bevel gear is damaged, the material belt hole is not properly clamped, there is interference from foreign objects, the spring is aging, there is an electrical fault, and the feeder fails to take in materials or takes in materials improperly, causing material throwing. The feeder is damaged. Solution: Adjust the position of the feeder, clean the feeder platform, and replace the damaged components or the feeder.

In conclusion, the solution to the material dispensing problem of SMT surface mounters requires addressing it from multiple aspects. By conducting regular maintenance and inspections of the equipment, strengthening incoming material testing and communication with suppliers, and optimizing program settings, we can effectively reduce the dispensing rate, increase production efficiency, and lower production costs.
