How Vision3D Safeguards Dimensional Accuracy for Zhijie V9 from Prototype Trial to Mass Production
Recently, LUXEED V9, the first panoramic intelligent flagship MPV under HIMA (Harmony Intelligent Mobility Alliance), officially opened pre-orders, with orders exceeding 22,500 within 72 hours amid soaring market popularity.
Behind its outstanding market performance lies the extreme safety standards set by LUXEED V9 for vehicle body structural integrity.
Notably, the rear floor of the LUXEED V9 integrates up to 78 separate individual components from conventional structures into a single integrated piece, cutting component weight by over 15%. Nearly one hundred welding points are eliminated, drastically boosting the overall rigidity and force transmission continuity of the rear structure. Deformation of the passenger compartment during collisions is significantly reduced, delivering the same level of safety protection for third-row passengers as those in the front row.
Achieving both lighter vehicle weight and superior crash protection, the LUXEED V9 realizes dual advancements in lightweight design and passive safety performance.
Yet there is an unavoidable hurdle for die castings moving from prototype trial to mass production: how to verify and control dimensional accuracy.
The rear floor features complex structures and drastically varying wall thicknesses. During the filling and solidification of aluminum alloy, not only internal quality must pass inspection, but precise external dimensions also determine seamless assembly with the vehicle body.
Such castings boast denser metallurgy, thinner wall sections and more integrated structures, yet they come with tighter tolerance margins. Distant structural features are hard to access for measurement, and intricate complex features cannot be fully captured by conventional inspection methods. If dimensional deviations slip through undetected into subsequent processes, they may trigger assembly interference and uneven gap & flush, impairing overall vehicle quality and safety performance.
Therefore, deploying high-precision full-dimensional measurement solutions is critical to guaranteeing the quality of the LUXEED V9 rear floor.
Rapidly validate process feasibility at the prototype stage
Shorten iteration cycles
Consistently maintain dimensional consistency after mass production launch
Vision3D’s Automated 3D Inspection Solution for Integrated Die-Cast Rear Floors
has been deeply embedded into the trial-manufacturing
and production system of the LUXEED V9 rear floor.
- High Precision
This solution adopts the PowerScan 5M330 Pro structured-light scanner with a single-frame measurement accuracy of 0.02 mm. It captures millions of point clouds in a single scan to cover all features including position tolerance of machined holes, profile tolerance of blanks and wall thickness uniformity, enabling efficient full-dimensional inspection with high precision.
- High Efficiency
No marking or spray coating required; one-click startup. Equipped with servo-driven rotary table and multi-angle trajectory planning for robotic arms, delivering full coverage without blind zones at the bottom. Supported by 10-Gigabit fiber transmission and GPU parallel computing, each single-frame scan takes less than 0.2 seconds, enabling rapid full inspection of mass-produced parts.
- Data Visualization
A visual inspection report is automatically generated once scanning finishes. Contour color difference diagrams, wall thickness analysis and dimensional feature evaluation allow process engineers to quickly judge filling uniformity and dimensional stability. Forward feedback of defects can be realized to optimize die-casting parameters, drastically shortening the prototype iteration cycle.
The implementation of this inspection verification system is backed by Vision3D’s profound technological accumulation in automated 3D measurement.
Specializing in independent R&D and industrial application of high-precision structured-light 3D measurement technology, Vision3D stands as a key domestic player in automated 3D inspection for integrated die-casting. Its core product portfolio includes structured-light 3D scanners, automated inspection stations and matched metrology software, serving numerous leading OEMs and auto component suppliers.
LUXEED V9 has completed the whole verification process from scratch. Vision3D’s structured-light measurement solution will shift its focus from prototype validation to mass production quality control, continuously undertaking full-dimensional inspection tasks and providing traceable dimensional data infrastructure to underpin LUXEED V9’s safety commitments.
