Multi-beam eccentricity jig — a camera measures and judges all 24 beams of a bar sensor in turn

A long linear stage on a workbench steps the camera from beam to beam along a bar-type multi-beam sensor and photographs each light spot. LinkVion measures each spot's width, eccentricity and size, judges every beam and the whole product OK or NG, and shows the result table, per-beam review and event log on one screen.

Example setup

This is an example setup, not a customer installation. The camera images are synthetic and the moving axis is simulated by a script. The sensor model names on the screen are made-up sample text. The values are not for real inspection decisions.

24beams — 59 mm pitch, photographed in turn
5rules per beam — width measured on X and Y, eccentricity X and Y, size range
3 NGin the demo run — beams 7, 15 and 20, product NG
1screen (1600×1140) — image, table, review, controls, charts

Running it

From start to verdict, the carriage on the same beam as the screen

The jig is computer-rendered, and the monitor shows a recording of the run screen with the same sample running in LinkVion. The camera carriage follows the position values logged during the recording, so it sits over beam N while the screen measures beam N. It recreates the screen of a real inspection jig built in 2015, now in LinkVion.

Example setup

Start → beams 1 to 24 at 2 s each (the measured window lights red) → NG on 7, 15 and 20 → complete, 3 NG → return home → row 7 opened for review. Top left shows the monitor's axis strip and per-beam review close up · 59 s

The jig is computer-rendered for illustration. The two meters show the voltage and current (simulated) from the recording. In the English video a camera-sync wait is fast-forwarded (marked on screen) so it shares the Korean video's timeline. You cannot run it on this page.

On the screen

One inspection run

  • Vision inspection (spot width, eccentricity, size)
  • Per-beam and product judgment
  • Axis stepping by script
  • Per-model limits (recipes)
  • Result table, per-beam review, charts
  • Run report and event log
  • Korean and English screens
Step and shoot
A script moves the camera by the beam pitch (59 mm), waits for the read time and takes the picture. On real equipment this is where the target position goes to the motion controller and the script waits for in-position.
Measuring the spot
Along horizontal and vertical lines through the reference point the spot's half-maximum width and centre are measured, giving width, eccentricity (Offset X and Y) and size. Pixel values are converted to mm with the pixel pitch.
Judgment
A beam is OK when both widths are measured, the eccentricity is within the limit and the size is within range. The product is OK only when every beam is. In the demo run beam 7 (eccentricity) and beams 15 and 20 (size) are NG.
Records
The result table, per-beam review and event log stay on the screen, and each run writes a one-line summary report (CSV). Beam count, pitch and limits per sensor model are switched by recipe.

Limits

What this case does not show

  • Not real equipment. The jig is computer-rendered, with a recording of the same sample running in the product laid over the monitor. The carriage follows the position values logged during the recording.
  • The 24 camera images are synthetic and the axis is simulated by a script. Do not use it as is for inspection decisions.
  • Names on the screen, such as sensor model names, are made-up examples.
  • There is no live version on this page, only the video. The sample needs the vision inspection feature to run.
