The CTS-1000
is designed as a flexible platform used to integrate a variety
of different process modules and handling equipment. Although
designed primarily for electronic components, this versatile system
can be configured for a wide range of applications that require
the automated manipulation of parts.
The CTS-1000
can be equipped with load and/or unload handlers such as:
- Auer boats
- Jedec and
other tray types
- Custom
magazines or cassettes
- Tube handlers
- Bowl feeders
- Tape and
Reel
Process modules
which can be integrated, include, for example:
- Vision
Alignment Systems
- Lead scanning/inspection
systems
- Component
inverters/rotators
- Component
lead trim and form presses
- Component
marking systems
- Component
test equipment
In the typical
application described here, the system is configured for component
trim and form and vision inspection operations. This system has
two handlers, a trim and form press, a vision alignment and inspection
system, positioning shuttle slides, a transfer robot and a part
inverter.

- Lead Scanning
to Tray Cassette Handler
A cassette
of full Auer boats is loaded into the Auer Cassette Handler. Boats
are unloaded from the cassette (top to bottom or bottom to top
- sequence is customer selectable, depending on process requirements).
The shuttle
picks a boat from the cassette and moves it to the wait position
sensor. If the sensor detects a boat, the shuttle will proceed
to position the boat at the pickup point; if not, the shuttle
returns to pick the boat from the next slot in the cassette.
The transfer
arm robot picks the component from the Auer boat, and transports
it to the Vision Alignment station. The part orientation is corrected
before it is placed in the Trim and Form press. After the trim
and form operation, the transfer arm robot transfers the component
from the press to the Lead Scanner for full inspection.
Good components
are then transferred to the Tray Cassette Handler. Rejected components
can be reprocessed through trim, form and inspection or transferred
to a reject tray. When the Auer boat is empty, the shuttle returns
the empty boat to the cassette. The handler then indexes the next
boat into position, and the process is repeated until all the
components have been processed through Vision alignment, Trim
and Form and Lead Scanning operations and have been transferred
to trays in the Tray Cassette Handler.
A cassette
of empty trays is loaded in the Tray Cassette Handler. The shuttle
moves the top or bottom (customer selectable) tray to the loading
position on the shuttle slide rails. A hard stop ensures precise
location of the tray.
The transfer
arm robot places the processed parts into the trays. When each
tray is full, it is reloaded into the tray cassette by the shuttle.
When all trays in the cassette have been filled, the cassette
is easily and quickly removed from the handler.
In some cases,
it is necessary to invert the components prior to or after Trim
and Form. In this case, the transfer arm robot places the part
on the inverter, and the inverter flips the part through 180°.
The transfer arm then re-picks the part and continues its sequence.
The transfer
arm can also rotate the part through 360°, if it is necessary
to change part orientation, e.g. when placing into output trays.
