Industrial lenses play a core perception role in the entire process of automobile manufacturing. They drive the intelligent upgrade of quality control, automated assembly, safety testing and other links through high-precision imaging and intelligent analysis technology. The following are its main application scenarios and technical solutions:
1. Precision inspection of core components
-Engine and power system
Internal defect inspection of cylinder block/crankcase:
Use ultra-fine industrial endoscopes (such as Microvision Optoelectronics K series) to penetrate the cavity to detect casting pores, slag inclusions and microcracks (accuracy up to 0.01mm), and the 360° rotating lens is combined with a six-color LED light source to solve the interference of metal reflection.
Turbocharger flow channel inspection:
High-resolution lenses observe the internal surface roughness to ensure turbine efficiency, and the single inspection time is shortened by 75% compared with traditional disassembly.
Gearbox and transmission parts
Gear burr identification:
Dual telecentric lenses (0.5X-1X) are combined with 3D vision technology to quantify burr size (length/height tolerance ±0.01mm) to avoid assembly jams.
Oil channel foreign body inspection:
Endoscopes with a diameter of ≤3.9mm penetrate the seal, and the AI-DIR module automatically marks 6 types of defects such as oil leakage and piston wear, with a false alarm rate of <0.3%.
2. Car body manufacturing and assembly
-Welding quality monitoring
Weld point defect identification:
A megapixel industrial camera with a low-distortion fixed-focus lens (distortion < 0.03%) can capture cold welding, over-welding and welding deviation in real time, with a detection speed of thousands of points per minute.
Laser welding process imaging:
Anti-glare coated lenses monitor weld penetration to ensure structural strength, with a missed detection rate of < 0.1%.
-Coating and sealing process
Glue path continuity detection:
360° full-view monitoring, dynamic identification of glue breakage, offset and glue width deviation (compatible with black and white glue), with a maximum beat of 0.5m/second.
Coating uniformity analysis:
Line scan lenses (line frequency > 80kHz) scan the body surface to detect defects such as orange peel and sagging, and grade and evaluate with deep learning algorithms.
3. Appearance and safety component quality inspection
-Full-dimensional inspection of automotive glass
Surface profile measurement:
Coordinate measuring machine (CMM) combined with laser triangulation, with an accuracy of ±0.01mm, ensures the fit of the windshield.
Stress and edge defect identification:
Polarized light technology detects residual stress, and high-power microscope lens detects microcracks to prevent the risk of spontaneous rupture.
Transmittance and haze control:
Special optical lenses quantify the proportion of scattered light to ensure that the clarity of vision meets traffic safety standards.
-Body surface defect screening
Scratch/dent detection:
3D vision technology (such as structured light scanning) reconstructs surface morphology and identifies defects ≥0.1mm.
Coating layer uniformity evaluation:
Multispectral lens analyzes coating thickness and color difference to ensure appearance consistency.
4. Intelligent auxiliary system
-Robot guidance and positioning
Disordered grasping of parts:
M12 micro lens (diameter ≤12mm) equipped with AGV car, 3D visual positioning accuracy ±0.5mm, adapt to reflective and oily environment.
Precision assembly calibration:
Telecentric lens (depth of field ≥30mm) guides the alignment of engine cylinder head and crankshaft, assembly error <0.01mm.
-Production traceability and code recognition
DPM code reading: High-resolution fixed-focus lens (200 lp/mm) identifies the direct marking code (DPM) of parts, complex font recognition rate >99%
5.Solutions and technological breakthroughs
6.Selection core parameter guide
Accuracy adaptation:
Detecting 0.01mm defects requires a lens resolution of ≥140 lp/mm (corresponding to a 10M pixel camera).
Environmental tolerance:
Nano-oleophobic coating is used for oily scenes, and IP54 protection level is required for dusty environments.
Dynamic performance:
For high-speed assembly lines, large aperture fixed focus lenses (F2.8) are preferred to reduce motion blur
