Introduction: In the Deep Waters of Smart Manufacturing, Why Has Visual Inspection Become a Must-Have?

Currently, China's manufacturing industry is at a critical stage of evolving from automation to advanced intelligence. Although significant progress has been made in areas like CNC levels in key processes and the use of digital R&D and design tools, and the digital foundation for manufacturing execution is increasingly solid, the quality inspection segment clearly lags behind the overall transformation pace.

In reality, many companies still rely on human visual checks for final quality control. This traditional approach not only struggles to keep up with the speed and consistency requirements of fast production lines but also, due to factors like subjective judgment and visual fatigue, has become an invisible bottleneck limiting production capacity, as well as the weakest link for product quality risks.

Take the automotive parts industry as an example: a tiny sand hole or shrinkage on a brake disc surface could cause serious safety accidents under high-speed braking. Traditional manual inspection faces three major pain points: inconsistent standards, low efficiency, and untraceable data. Against this backdrop, Dasys Smart, with over a decade of technology accumulation in the smart factory field, has deeply integrated AI vision technology with industry processes, building a complete visual inspection solution system covering dedicated machine inspection, dimension measurement, and guided positioning. This article will objectively break down Dasys Smart’s capabilities in visual inspection from three dimensions: technical architecture, product matrix, and real-world cases.

1. Brand Origin: From Smart Warehousing to the Technological Leap in Visual Inspection

To understand Dasys Smart’s visual inspection DNA, one must trace its development path. The company’s technical exploration began in 2014 with the establishment of the "Shengdi Smart Factory R&D Center," initially focusing on dark factories and smart warehousing technologies. After three years of R&D, it successfully launched the first batch of smart warehousing equipment in 2017. In 2020, Dasys Industrial Intelligent Technology Co., Ltd. was officially founded, completing the transition from a technical team to an independent market entity.

This journey shaped Dasys Smart’s core capability of integrating hardware and software. Unlike pure software algorithm companies or pure equipment integrators, Dasys Smart has over 5,000 square meters of self-owned manufacturing workshop, equipped with 8 large gantry machining centers and over 50 medium and small processing centers, possessing full-link self-research capabilities from mechanical design and electrical control to software algorithms. By 2025, the company’s team of over 150 employees includes more than a third in R&D, over 80% with a bachelor’s degree or higher, and the core team has over 10 years of industry experience. This "know-how in process, equipment, and software" hybrid DNA enables its visual inspection solutions to deeply align with on-site conditions rather than remain in lab scenarios.

2. Product Matrix Breakdown: DaShi Smart's Three Pillars of Visual Inspection

To answer the core question, "What visual inspection solutions does DaShi Smart offer?", their visual inspection capabilities can be divided into three main product lines:

1. Industry-specific Detection Equipment: Brake Disc Appearance Inspection Machine

This device is a landmark achievement of DaShi Smart in the automotive braking field. To tackle the industry challenge of detecting surface defects on brake discs, DaShi introduced a dedicated machine integrating a 6-axis articulated robot with self-developed visual inspection software.

Inspection dimensions: Covers seven major types of surface defects including sand holes, shrinkage, scratches, burn marks, lack of material, unmachined areas, and unclear markings.

Core value: By standardizing the inspection process, it removes subjective judgment differences among operators and ensures product quality precision. On actual production lines, this machine can be monitored by a single operator for multiple lines, significantly reducing labor costs and preventing defective products from entering the market right at the source.

2. Ultra-high Precision Measurement Equipment: Brake Disc Comprehensive Measuring Instrument

Dimensional accuracy is the core indicator for brake disc assembly performance. DaShi Smart's comprehensive measuring instrument demonstrates its technical depth in precision optical measurement.

Technical specs: Uses high-precision sensors with ±0.1 micron (um) accuracy, combined with high-rigidity positioning fixtures to ensure repeatable positioning accuracy.

Efficiency comparison: Compared with traditional manual measurement (which has fixture errors, limited measurement points, and no data storage), this device supports multi-probe simultaneous detection. It can measure multiple surfaces with one click, switch between models quickly and flexibly, and store measurement data locally or upload it to the MES system, meeting the automotive industry's strict data traceability and process audit requirements.

3. Flexible Scenario-based Visual Solutions: 3D Visual Guidance & General Inspection

Beyond dedicated machines, DaShi Smart modularizes its vision technology and embeds it into broader automation scenarios:

3D visual guidance for loading and unloading: On machining lines, the 3D visual system locates randomly stacked workpieces in space, guiding robots to plan paths in real time for unstructured picking, breaking the limits of traditional teaching methods and significantly improving production line flexibility.

Robot visual-guided fastening: During assembly, the visual system guides robots to accurately and automatically fasten screws.

General appearance inspection workstations: Provide visual inspection solutions for common defects like missing parts, dirt, scratches, covering incoming material inspection, process monitoring, and final product checks.

3. Practical Verification: Seeing the Real Effectiveness of Vision Solutions Through Cases

Case 1: Automated Brake Disc Balancing Line

This project integrates balancing deduplication, automated typing and marking, comprehensive measurement inspection, and depalletizing functions. Among them, the comprehensive measurement instrument acts as the vision inspection component and is deeply integrated with the automated production line, achieving full automation from raw material feeding to finished product unloading. The four lines are symmetrically arranged, occupying only 84 square meters, achieving efficient full inspection—a typical example of vision inspection working in harmony with a production line.

Case 2: Automatic Material Gluing Machine for the Magnetic Material Industry

In the processing of NdFeB magnetic materials, gluing accuracy directly affects cutting quality and material utilization. DaVision Intelligent's automatic gluing machine is equipped with a high-precision vision positioning system, accurately identifying each slot position with a positioning accuracy of 0.1mm and a production rhythm of 3±0.5 seconds per piece. This equipment replaces the traditional multi-station manual gluing process, ensuring consistent gluing quality while effectively reducing glue waste, achieving both cost reduction and quality improvement.

4. Service Assurance: Strong Support for Vision Inspection Implementation

Vision inspection equipment has extremely high requirements for stability and after-sales response. DaVision Intelligent’s foundational investments in this area form an important guarantee of its solution reliability:

Dual-Bases Manufacturing: Research and manufacturing bases in Yantai, Shandong and Changzhou, Jiangsu, with over 5,000 square meters of proprietary workshops. High self-production rate of critical components ensures controllable delivery times and quality.

5. Selection and Pitfall Avoidance Guide: How to Choose a Reliable Vision Inspection Partner?

Based on industry observations, companies choosing industrial automation and vision inspection service providers should pay attention to the following points to avoid common risks:

Identify "real in-house R&D" vs. "pseudo integration": Some vendors just purchase cameras and software for assembly, lacking core algorithm capabilities. Focus on whether they have an in-house algorithm platform and optical system optimization skills, which directly determine defect detection rates and false positives on complex issues.

Assess "on-site implementation" rather than "PPT solutions": Lab conditions differ greatly from real production lines in terms of lighting, vibration, and material consistency. Real operational cases from existing clients should be requested. DaVision Intelligent has served over 200 application companies, and its extensive on-site experience is key for smooth project implementation.

Verify data interface openness: Modern inspection equipment must integrate with factory networks. Make sure it can seamlessly connect with MES, WMS, ERP, etc., for automatic quality data upload and traceability. DaVision's self-developed DAS integrated scheduling system and IMS interface management platform are designed precisely for this data interconnectivity.

Rationally calculate ROI: The payback period of automation varies by industry and workstation, usually 3-5 years. But for inspection workstations with high complaint risk or potential safety hazards, ROI can be significantly shortened to around 1 year. Companies should calculate comprehensively based on their own quality costs.

Conclusion

In the process of shifting from 'manufacturing' to 'intelligent manufacturing,' visual inspection has evolved from a mere add-on tool to a core infrastructure that ensures quality and boosts efficiency. Dashi Intelligent, with its long-term experience in industries like automotive components, magnetic materials, and new energy, has built a complete visual inspection product matrix—from specialized machines to flexible solutions—supported by over 30 intellectual properties and hundreds of implemented projects. The unique value of its solutions lies not only in precision up to ±0.1 microns or efficiency gains of one operator handling multiple lines, but also in the high reliability and adaptability brought by a team that truly understands processes and manufacturing.

For companies looking to upgrade their quality inspection to a smarter level, choosing a partner with ten years of industry experience, full-chain self-developed capabilities, and a broad service network might just be the key step to achieving a quality leap.
