Abstract

Feeder assemblies are used to present the taped and reeled surface mount components to an automatic placement machine, such as the Fuji CP 3. By encoding feeder assemblies with an identification, the chance for loading errors would be reduced and maintenance and performance tracking would be improved.

FEEDER ASSEMBLY IDENTIFICATION

by Timothy J. Mennitt

   Feeder assemblies are used to present the taped and reeled surface mount components to an automatic placement machine, such as the Fuji CP 3. By encoding feeder assemblies with an identification, the chance for loading errors would be reduced and maintenance and performance tracking would be improved.

  The current design of many placement machines, uses a barcoding scheme to identify both the slot and the reeled component part number. There is a barcode on the slot (see figure 1) as well as on the reel. The process of loading the parts reels onto the machine follows these four steps.

1) Read the barcode on the reel into the machine.
2) The machine responds with the slot location for that particular part number.
3) Verify by reading the barcoded slot number.
4) Insert the reel/feeder assembly into that slot. There are two problems with that methodology.

  1) If the slot location is in between two already filled locations, it is virtually impossible to wand in the slot location (see figure 1). This can happen when replacing a reel or when setting up out of sequence.

  2) There is no confirmation that the correct feeder is placed in the correct slot location. The system depends on the operator to place the feeder in the wanded in slot. Operators can still make these mistakes.
