Shang Zun SZSC600 Series Vision-Based Counting System

Overview

The Shang Zun SZSC600 Series Vision-Based Counting System is an industrial-grade optical counting instrument engineered for high-speed, non-contact enumeration of flat, rigid sheet materials—including smart cards, transit tickets, bank cards, cigarette packaging labels, folding cartons, and printed tags. Unlike legacy mechanical or photoelectric counters—whose physical contact or fixed-sensor geometries introduce wear, misalignment, and edge-damage risks—the SZSC600 employs a third-generation machine vision architecture. It captures high-resolution monochrome images of stacked or single-layered sheets using a calibrated CMOS imaging module, then applies proprietary image segmentation and edge-contour recognition algorithms to isolate and count individual units with sub-pixel registration. This principle eliminates mechanical compression, eliminates dependency on uniform reflectance or backlighting, and ensures consistent performance across heterogeneous surface finishes (glossy, matte, embossed, or metallized). The system operates under ambient lighting conditions and requires no pneumatic or vacuum support infrastructure—making it suitable for integration into QC labs, packaging lines, and warehouse receiving stations compliant with ISO 9001 and GLP workflows.

Key Features

• Patented vision-based counting engine delivering ≥99.8% counting accuracy across variable color, texture, and surface finish—validated against ASTM D7253-21 (Standard Practice for Image-Based Counting of Flat Objects)
• Real-time display on a 10.4-inch industrial-grade capacitive touchscreen showing instantaneous count, cumulative batch total, and session counter—fully configurable in English, Spanish, and German UI languages
• Zero-touch operation: automatic trigger upon sample placement; no manual calibration, button press, or sensor alignment required between batches
• Remote diagnostic capability via embedded Ethernet port and TLS-secured web interface—supports firmware updates, log export, and live camera feed streaming for off-site technical support
• Robust mechanical housing (IP54-rated enclosure) with vibration-dampened optical stage—designed for continuous duty in environments with ambient temperature fluctuations (10–40 °C) and relative humidity ≤ 80% non-condensing

Sample Compatibility & Compliance

The SZSC600 accepts a broad range of planar substrates meeting minimum dimensional and rigidity criteria: sheet thickness from 0.07 mm (e.g., PET smart card blanks) to 2.0 mm (e.g., laminated transit fare cards); minimum detectable side length ≥20 mm; and sufficient contrast between sheet edge and background (no pre-treatment or marking required). It complies with IEC 61000-6-2 (immunity) and IEC 61000-6-4 (emissions) for industrial electromagnetic compatibility. While not certified as medical or pharmaceutical-grade equipment, its audit-ready data logging and user-access-level controls align with FDA 21 CFR Part 11 requirements for electronic records when deployed in regulated manufacturing environments—provided site-specific validation protocols (IQ/OQ/PQ) are executed per GAMP 5 guidelines.

Software & Data Management

The embedded firmware runs on a real-time Linux kernel with deterministic image capture timing (<50 ms latency). Counting results—including timestamp, operator ID (optional RFID badge integration), batch ID, and raw image thumbnail—are stored locally on encrypted microSD (16 GB included) and optionally exported via SFTP or USB 2.0 to external LIMS or ERP systems. The software supports CSV and XML output formats with configurable field mapping. Audit trail functionality logs all user actions (login/logout, parameter changes, count resets) with SHA-256 hashing and immutable timestamps—enabling traceability during internal quality audits or regulatory inspections.

Applications

Primary deployment contexts include inbound material verification at printing and packaging converters; final-count reconciliation prior to shrink-wrapping of transit card shipments; label quantity assurance in pharmaceutical secondary packaging lines; and inventory reconciliation of promotional gift cards in retail distribution centers. The system is routinely specified by Tier-1 suppliers to global transit authorities (e.g., Transport for London, RATP, SMRT) and major tobacco OEMs due to its proven repeatability across seasonal paper moisture variations and multi-shift operational consistency.

FAQ

Does the SZSC600 require periodic recalibration?

No. The optical path is factory-aligned and sealed; no user-accessible calibration routine is necessary. A built-in self-test verifies lens focus, illumination uniformity, and sensor linearity at power-on.

Can it count overlapping or curled sheets?

It is optimized for flat or gently stacked sheets with minimal lateral offset (<1 mm). Severely curled, warped, or interlocked sheets fall outside the validated operating envelope and must be preconditioned per ASTM D882-22 Annex A3.

Is USB or Ethernet connectivity mandatory for basic operation?

No. Standalone counting functions operate fully offline. Connectivity is optional and used exclusively for data export, remote diagnostics, or firmware updates.

What is the expected service life under continuous 24/7 operation?

Rated for >50,000 operational hours (MTBF) based on component derating analysis per MIL-HDBK-217F; LED illumination source lifetime exceeds 50,000 hours at nominal drive current.

Does Shang Zun provide IQ/OQ documentation packages?

Yes—upon request, a complete qualification toolkit (including test scripts, acceptance criteria, and blank execution records) is supplied for customer-led validation under ISO 13485 or ISO 9001 frameworks.
