Armrest Console Lid and Center Console Wrapping Inspection
Armrest console lid and center console wrapping inspection: for wrinkles, delamination, skipped stitches, stains and scratches on armrest console lids, elbow pillow upper cover plates and center console wrapped parts, low-angle and side lighting highlight stitch lines and undulation; AI judges and marks defect positions, outputs OK/NG and supports data traceability.
Application Overview
Appearance inspection of edges and stitching on wrapped armrest console lids and center consoles
It inspects wrapping wrinkles, delamination, stains, scratches and stitch quality on armrest console lid / center console wrapped parts; the three-dimensional wrapped surface is imaged from multiple angles, and AI judges the defects and marks their positions.
Armrest console lids and center console wrapped parts are interior trim components that are relatively small but have many curved transitions; wrapping is most prone to problems at edges and corners (wrinkles, delamination, skipped stitches), and these are high-frequency touch areas for users with high appearance requirements.
This station addresses the appearance of these small three-dimensional wrapped parts, focusing on wrapping quality at edges and corners, stitch integrity, and surface stains and scratches; contour fit is also compared.
Inspection is carried out after the wrapping process step, imaging one part at a time; additional illumination at corners highlights defects, adjusted according to the part type.
inspection Targets
What This Station Actually Has to Judge
| inspection item | Description |
|---|---|
| Wrapping Wrinkles | Wrinkles and indentations at ridge lines / corners |
| Layer separation | Corner blistering, delamination |
| Stitch Quality | Skipped stitches, broken thread, uneven stitch pitch |
| stain | Oil Stains, Fingerprints |
| scratch | Surface Scuff |
| Contour Fit | Wrapped edge fits the profile surface |
| damage | Holes, Missing Corners |
Why Inspect
Problems with manual visual inspection at this step
The armrest console lid / center console are high-frequency touch areas, where wrapping wrinkles, delamination and skipped stitches at edges and corners most affect perceived quality; these small parts also have many corners, and manual visual inspection is prone to fatigue and missed judgement.
Stitch-line defects are fine in form and hard to capture with fixed thresholds, so the stitch line must be handled as a feature recognition task rather than simple grayscale segmentation.
- Ridgelines and corners are most prone to wrapping defects
- High-touch areas have high appearance requirements
- Skipped stitches are fine; thresholds are hard to write
- Small parts with many corners; manual labor misses them easily
How Inspect
Stations and Inspection Chain
- 01 Load and secure the wrapped part
- 02 Main view images the main surface
- 03 Add low-angle light at corners
- 04 Seam feature recognition
- 05 AI segmentation of wrinkle delamination
- 06 Classify and judge the defect grade
- 07 Outputs OK/NG at the marked position
- 08 Interlocking rejection/sorting
- 09 Image and data archiving
How to Inspect
For small three-dimensional wrapped parts, multi-angle imaging with a main view plus corner fill lighting is used; low-angle light highlights wrinkles and delamination, and stitching is recognized as a linear feature; this is an imaging method that combines curved surfaces and linear features.
Technology Architecture
Optical imaging layer · algorithm layer · vision software layer · automation control layer
The product is not a single "camera inspection" but a four-layer coordinated system: the optics layer determines whether a defect can be imaged, the algorithm layer determines whether it can be resolved, the software layer handles judgement and recording, and the automation layer handles integration with the production line.
First Layer: Optical Imaging Layer
Dark materials lower the brightness of both the defect and the background, and simply increasing gain does not improve the signal-to-noise ratio. The usual approach is to use low-angle light to highlight surface relief, use polarization to suppress highlights, or adopt a morphology imaging method that is insensitive to color, and to carry out dedicated illumination validation for that leather.
Layer 2: Algorithm layer
Stitching run and skipped stitches are judged with contour and gray-level analysis, and seam offset is measured with sub-pixel methods; defects with variable morphology such as wrinkles, delamination and stains are left to AI classification and segmentation.
Third Layer: Vision Software Layer
Unified management of product recipes, capture parameters, algorithm invocation, inspection results, defect classification, image traceability and report statistics.
The Fourth Layer: Automation Control Layer
Integrate with locating fixtures, loading and unloading mechanisms, sorting mechanisms and PLC/MES data systems to complete triggering, sorting and data return.

Item Deployment
Ten steps from sample analysis to delivery
- 01 Product sample analysis: confirm workpiece dimensions, material, color, stitch type and wrapping structure
- 02 Defect standard confirmation: define what counts as OK and what counts as NG, and build a defect sample set
- 03 Inspection requirements confirmed item by item: wrinkles, delamination, skipped stitches, stains, scratches and seam offset
- 04 Vision testing and illumination experiments: focus on validating imaging of stitching and dark leather surfaces
- 05 Station and shooting angle planning: determine viewing angles from the workpiece curvature and seam direction
- 06 AI model training: build a defect recognition model using actual samples
- 07 Inspection zone division and acceptance criteria definition: stitching, edges, and corners are set as separate zones
- 08 Master sample baseline setup and parameter tuning
- 09 Complete machine joint debugging and trial run: integrate acquisition, the software platform and inspection logic, and tally over-rejection and escape
- 10 On-site validation and delivery: continuous running tests according to the actual production cycle time and quality standards, acceptance, training and maintenance
Information to Prepare
Recommended to prepare: the physical product, product photos, 3D/CAD data of the product, product dimensions, material and color, inspection area, defect samples (OK samples and NG samples), the minimum defect size to be detected, production cycle time and daily output, the current manual inspection method, and whether inspection data traceability is required. The more complete the information, the easier it is to accurately plan the imaging method, number of cameras, and AI inspection model.
