Defect detection
Detect missing features, contamination, damage, surface anomalies or assembly defects where the visual contrast is measurable and repeatable.

Machine vision & automated quality control
Develop and integrate camera-based inspection systems that verify products during production: presence, orientation, dimensions, labels, codes, surface defects, assembly condition and other measurable visual criteria.
Turn visual quality checks into a controlled production process
Manual inspection can be effective for low-volume work, but it becomes difficult to keep consistent as production speed, product variety and documentation requirements increase.
A machine-vision project should start with the defect or characteristic that must be detected, not with the camera model. Techsmart defines the inspection objective, evaluates product presentation and lighting, selects suitable optics and image-processing methods, and integrates the result with the PLC, HMI, reject mechanism and production data.
Inspection capabilities
Measurement & position
Check dimensions, alignment, orientation, spacing and part position against defined tolerances.
OCR & code verification
Read printed text, dates, serial numbers, barcodes and 2D codes and compare them with production requirements.
Label & packaging inspection
Confirm label presence, position, print quality, correct code and packaging configuration before release.
Traceability
Associate inspection results with product IDs, batches, timestamps or line data where the production architecture supports it.
PLC / reject integration
Trigger inspection, exchange results with PLCs and control reject gates, stops, alarms or rework handling.
How the system is engineered
01
Define the defect
Samples, tolerances, defect limits, line speed, product variation and pass/fail criteria.
02
Prove the image
Lighting, optics, camera position, triggering and image contrast are evaluated before full integration.
03
Integrate controls
Inspection logic, PLC handshakes, HMI status, reject control, alarms and data interfaces.
04
Validate production
Test good and defective samples, tune thresholds, confirm reject timing and document the system.
Quality control needs repeatability
Vision systems are most successful when the product presentation is controlled. Changes in lighting, background, reflections, vibration, position or product variants can affect image quality. These factors must be considered as part of the machine design.
For existing lines, the integration may include new guarding, triggers, encoders, fixtures, reject devices, PLC logic, HMI screens or traceability links.
Useful information for an initial review
- Photos/video of the product and line
- Good and defective samples
- Line speed and cycle time
- Defect sizes and tolerances
- Available installation space
- PLC/control platform
- Required result handling or reject method
Need a feasibility review?
Send product photos, defect examples and line information. The first question is whether the required feature can be imaged reliably in production conditions.
