“SAM” module, and Signature
Technologies “SamView™” software
package can be used to perform non-contact measurement of the dimensions of
specific features on manufactured parts including internal dimensions at very
high speeds. Common applications include connector internals and terminal
The illustrated method can perform the same type of test
every stroke of the machine so that each part can be individually verified as
having the proper internal geometry.
|The system works by passing a laser beam through the formed
part, and aligning the beam so that it is 50% blocked when the internal
feature dimension is at nominal. The SAM™
module captures the beam information, and performs a Go/No-Go evaluation
as the part passes by the measurement station.
Low pressure air is used to keep the optics clean and part
tracking is available to enable the rejection or sorting of
non-compliant parts without stopping the process.
system can "time" the measurement so that the part is
"scanned" as it passes the sensor during the feed progression
as illustrated in the Graph.
The measurement can be absolute, or comparative depending on the
Multiple sensors can be used in cases where there are several
different features to measure, or where multiple measurements are required. The SAM™
module can handle inputs in groups of 8 up to 56 total points.
Technologies can supply a wide variety of solutions to various
manufacturing process problems dealing with measurement, verification of
properties, tool condition, and machine health. We can also “close the loop” by performing process
adjustments in response to specific variations in force, location, or shape of
the work piece, as well as more simple controls which can track and reject
specific parts which don’t meet specific quality criteria.
