Feeders
Tape feeder: for parts on reel tapes. Specified by the tape width, like 8mm, 12mm,
16mm, 24mm etc.
We supply 3 types of tape feeders:
1. PX feeder. fastest and highest cost, easy to set up and use.
2. SX feeder(obsolete). We invented the very low cost SX feeder in 2009. A puncher is installed
on the machine head. The puncher comes down to press on the tape and pulls
the tape forward. Computer vision is used to find the part on the tape
before it is picked up. Weights are used to peel the tape. The weights
have to be moved up manually from time to time. We do not offer SX feeders
anymore on new production machines.

3. SX-2 feeder. Our innovation is faster than imitations. The SX-2 feeder is the second
generation of our low cost SX feeder. With the SX-2 feeder, the tape is
advanced at the same time that the part is picked up. Computer vision is
used to find the part on the tape as needed. The tape is peeled automatically.
No weights are necessary anymore. SX-2 feeders are faster and works better
for small parts than SX feeders.

Vibration feeder: for parts packed in tubes. It is also called tube feeder.
|
Tray feeder: for parts packed in trays. No special feeder is necessary, just a fixture to hold the tray.

Up looking video camera
|
Up looking video cameras are used to align the picked up part before it is placed on the PCB. The view field of a video camera is fixed, and is suitable for a limited range of part sizes. If a video camera's view field is good for small parts, like 0402 , 0603, it will not be good for big parts. It probably can see only a small portion of a big IC. Additional up looking video cameras have to be used to cover different sized parts.
