Common Issues and Solutions for Pneumatic SMT Feeders
As the demand for SMT machines continues to rise, particularly those produced by Samsung, pneumatic feeders have gained popularity in the assembly process. To assist operators and technicians, YEETAI has compiled a list of common problems with pneumatic feeders along with their solutions for learning and reference.
1. Error Message: Index Error
Solution: This issue is often caused by the cylinder not resetting within the designated delay. Check if the material is properly wound on the tape and manually rotate the tape gear to see if it is jammed.
2. Error Message: Yellow Feeder Light
Solution: This indicates that the sensor is unable to detect the block. Adjust the cylinder stroke screw or inspect the sensor to ensure it is functioning properly.
3. Error Message: Open Error (Cylinder Not Moving)
Solution: This fault may stem from the cylinder failing to operate. Check sequentially for issues with the push pin, the solenoid valve wiring, the control board, the solenoid valve, the cylinder, and the air supply lines.
4. Error Message: Open Error (Cylinder Moves Slightly)
Solution: Replace the sensor to resolve this issue.
5. Error Message: Green Feeder Light, But No Operation
Solution: Inspect the push pin for integrity and check the control board for any faults.
6. Error Message: Feed Gear Not Turning or Slow Response
Solution: Examine the feed gear for any obstructions, ensure the cylinder is securely fixed, and verify normal air pressure. Check if the pressure cover is moving freely and ensure the cylinder operates smoothly. Adjust the cylinder stroke if necessary, clean and lubricate the pressure cover, and replace the cylinder if it feels jammed.
7. Error Message: Light Not Illuminating
Solution: Inspect the control board, reseat or replace connections, and check the switch for good contact.
8. Error Message: Frequent Tape Jamming
Solution: Check for foreign objects in the white gear and manually turn it to check for jamming.
9. Error Message: Gear Moves Back When Pushed
Solution: Adjust the stroke screw of the gear to rectify this.
10. Error Message: Component Profile Center Offset
Solution: If the small roller at the base of the feeder is deformed from impact, repair it using the appropriate tools.
