Machine Vision Test & Inspection Solutions

Machine Vision Test & Inspection Solutions integrate vision inspection, functional test, electrical test, automation, test software and production data into a complete automated test system. onTAP is not positioned as a camera distributor, vision algorithm company or general AOI equipment vendor. Machine vision is treated as a test resource inside automated test systems and integrated with electrical test, functional test, communication, load simulation and production automation.

Customer Challenges

  • Manual visual inspection can be insufficient when consistency, efficiency, data recording or automation is required.
  • Standalone vision equipment judges images, while integrated test systems also verify electrical performance, device function, communication, load/sensor response and visual output.
  • Vision inspection results depend not only on the camera, but also on lens, lighting, fixture, positioning, trigger, background and test flow.
  • Vision results need to enter the unified test flow for pass/fail, reporting, traceability and production actions.

Solution Approach

  • Treat vision processing as one test step inside test software rather than as isolated equipment.
  • Build a system link across test software, vision controller/PC, camera + lighting, fixture/positioning, DUT and electrical/functional test resources.
  • Select inspection tasks such as geometric/position inspection, appearance defects, LED color/brightness and LCD display status based on the object.
  • In the FCT sequence, trigger DUT functions, activate LED or display states, use camera capture and image analysis for judgment, then continue electrical or functional testing.
  • Correlate vision results with product ID, test data, reports and traceability records.

Deliverables

  • Machine vision test software integration
  • Engineering integration of camera, lighting, fixture, trigger and test sequence
  • LED / indicator functional-state visual verification flow
  • LCD / display basic defect inspection flow
  • Dimension, position, appearance and color-difference inspection flow
  • Integration of vision results with FCT, electrical test, reports and traceability
  • On-site commissioning, operator training and maintenance documentation

Business Value

  • Turns visual inspection from operator judgment into a repeatable, recordable automated step inside the test flow.
  • Combines vision results with electrical test, functional test, communication and load simulation into unified results.
  • Supports non-contact judgment of dimension, position, color, brightness and appearance.
  • Connects vision inspection to production data, reports and traceability through test software.
