1. Non-contact Optical Measurement to Solve Complex Hollow Feature Inspection of Laptop Shielding Steel Sheets

The metal shielding steel sheet is a core electromagnetic shielding component of laptops. It is thin and lightweight with numerous hollow holes and intricate structures, making it a long-standing difficult inspection item for laptop components.

Chongqing Wanwei automatic 2.5D vision measuring instrument adopts non-contact optical measurement. No physical contact with workpieces is required, fundamentally avoiding deformation and surface scratches of thin shielding steel sheets caused by compression. Equipped with a high-definition optical imaging system, the equipment can accurately capture tiny hollow features on steel sheets and efficiently complete high-precision measurement of critical dimensions including aperture size, hole positional tolerance and outline contour.

Accurate control of hollow dimensions and positional tolerances effectively eliminates assembly defects such as steel sheet misalignment, poor fitting and excessive assembly gaps, fully guaranteeing assembly accuracy of laptop components and overall product quality.

2. Batch Inspection with Tooling Positioning for Large-scale Quality Control of Laptop Middle Frames

As the core structural component of laptops, middle frames require continuous large-batch inspection during mass production. The Chongqing Wanwei 2.5D vision measuring instrument can be matched with dedicated positioning tooling to quickly fix workpieces and automatically calibrate inspection datums, realizing standardized automatic batch inspection.

The equipment can automatically collect key parameters in batches, such as X/Y axis spacing, assembly buckle dimensions and positioning hole features of middle frames, covering all critical dimensional measurements required for laptop middle frame assembly. It supports automatic export of inspection reports. All original inspection data is completely stored and accessible at any time without manual re-entry, greatly reducing labor costs for quality inspection. Complete inspection data facilitates product quality traceability and production process optimization, perfectly adapting to large-scale mass inspection scenarios in laptop manufacturing plants.

3. Flexible Optional Modules: One Machine for Multiple Purposes to Meet Full-scenario Precision Inspection of 3C Products

To satisfy diversified inspection demands for laptop components and various 3C electronic products, Chongqing Wanwei WV Series Automatic 2.5D Vision Measuring Instrument supports customized optional functional modules for flexible expansion, allowing one machine to handle multiple precision inspection scenarios: ✅ Optional Touch Probe: Accurately measure soft and special-shaped workpieces to expand the measurable workpiece range; ✅ Optional Laser Measuring Head: High-precision detection of height, step difference and flatness, compensating the weaknesses of two-dimensional optical measurement; ✅ Optional Coaxial Light Lens: Suitable for inspection of high-gloss reflective workpieces and tiny parts to improve imaging clarity under complex conditions; ✅ Optional Navigation Lens: Wide-angle global positioning, enabling quick switching between multiple measuring points and shortening the cycle time of batch inspection.

Based on multi-sensor composite measurement technology, this 2.5D vision measuring instrument can not only inspect laptop shielding steel sheets and middle frames, but also measure tiny components such as precision mobile phone accessories, precision stamping hardware and electronic connectors, delivering outstanding cost performance.
