Intelligent Weighing Cabinet

Intelligent Weighing Cabinet

Intelligent Weighing Cabinet is a high-precision material management solution developed by HYVODA for scenarios requiring “accurate weight measurement of materials, traceable inventory changes, and strict control of material usage”. It integrates one-compartment-one-scale high-precision weighing technology, intelligent data acquisition, and multi-modal access control to realize “automatic weight detection of materials, real-time inventory update, and full-process data traceability”—addressing core pain points of traditional material management such as “inaccurate manual weighing”, “cumbersome paper-based weight recording”, “difficulty in tracking material consumption”, and “high error rate in inventory counting”.

This product supports centralized management via a computer-based background and can automatically record key data (material weight, operator, operation time) for each access event. Each storage compartment is equipped with an independent weighing sensor, ensuring that even micro-weight changes (e.g., ±0.2g) of materials can be detected. It is an essential equipment for industries including electronics manufacturing, chemical engineering, pharmaceuticals, food processing, and scientific research to achieve refined material management and comply with quality control standards.

Features

  1. One-Compartment-One-Scale Design for High-Precision Weighing
    Each storage compartment is equipped with an independent high-sensitivity weighing sensor (strain gauge type), enabling dedicated weight measurement for a single type of material. The weighing system offers an accuracy of ±0.2g and a weight range of 0.1g-30kg (customizable for different compartments), meeting the measurement needs of both micro-materials (e.g., 0.5g electronic chips) and medium-weight materials (e.g., 20kg chemical reagents). This design eliminates cross-interference between materials in adjacent compartments (e.g., vibration from opening one compartment does not affect the weighing result of another) and ensures a weighing accuracy rate of ≥99.9%—far exceeding the 85% accuracy of manual weighing with a portable scale.
  2. Automatic Inventory Check & Weight-Based Access Judgment
    After the cabinet door is closed, the system automatically initiates an inventory check by collecting real-time weight data from all compartments. It compares the current weight with the last recorded weight to judge whether materials have been taken out or returned:

 

  • If the current weight is lower than the baseline: The system calculates the difference as the “taken-out weight” and records it as a “material retrieval event”.
  • If the current weight is higher than the baseline: The difference is recorded as the “returned weight” and marked as a “material return event”.
    The entire inventory process for 20+ compartments is completed within 15 seconds, and an electronic inventory report is generated immediately—replacing the time-consuming manual weighing and counting process (which takes 30-60 minutes for the same number of materials).

 

  1. Multi-Modal Identity Verification & Compartment-Level Permission Control
    Fitted with an Android industrial computer and a 10.1-inch touchscreen, the cabinet supports face recognition, fingerprint/vein recognition, and IC card recognition to ensure only authorized personnel can access specific compartments:

 

  • Face Recognition: Suitable for clean environments (e.g., pharmaceutical workshops) with a recognition rate of ≥99% and response time ≤1s.
  • Fingerprint/Vein Recognition: Ideal for industrial scenes where hands may be slightly dusty (e.g., electronics factories), with a false rejection rate of ≤0.01%.
  • IC Card Recognition: Compatible with employee ID cards, enabling quick access for shift workers (no need for biometric verification).

 

Permissions can be assigned at the compartment level: for example, only laboratory technicians can access compartments storing high-precision chemical reagents (weighing range 0.1g-500g), while general operators are limited to compartments with common materials (weighing range 1kg-10kg). This prevents unauthorized access to sensitive or high-value materials.

 

  1. Real-Time Weight Monitoring & Intelligent Early Warning
    The cabinet continuously monitors the weight of materials in each compartment and synchronizes data to the remote management background in real time, with two core early warning mechanisms:

 

  • Low Inventory Warning: When the material weight in a compartment falls below the preset safety threshold (e.g., 100g for a certain adhesive), the system triggers a visual alert (flashing yellow LED on the compartment door) and sends a restock reminder to the administrator (via email or background pop-up).
  • Abnormal Weight Change Warning: If the weight changes abnormally (e.g., a sudden drop of 50% in 1 minute, indicating possible spillage or theft), the system locks the corresponding compartment and records the event (time, operator, weight change) for traceability. For toxic or hazardous materials, the system can also link to an external alarm system (e.g., audible siren) to enhance safety.

 

  1. Data Traceability & Weight-Based Consumption Analysis
    The system automatically stores all weight-related data for at least 6 months, including:

 

  • Access Records: Operator, compartment number, operation time, before/after weight, and material type.
  • Inventory History: Daily/weekly weight changes of each material, showing consumption trends (e.g., 500g of a certain resistor used per week).
  • Abnormal Logs: Records of over-retrieval, weight anomalies, and unauthorized access attempts.

 

Users can export reports in Excel/PDF format (e.g., “Monthly Material Consumption Report”) to analyze material usage efficiency (e.g., identifying over-consumption of a certain component) and optimize procurement plans—reducing material waste by over 25% compared to traditional management.

 

  1. Rugged Structure & Emergency Protection

 

  • Corrosion-Resistant Material: The cabinet body is made of 1.2-1.5mm thick cold-rolled steel with an electrostatic spray coating, and the weighing platform in each compartment uses 304 stainless steel (optional) to resist corrosion from chemical reagents or moisture—suitable for harsh environments (e.g., chemical labs).
  • Shock-Absorbing Design: Each weighing sensor is equipped with a shock-absorbing gasket to reduce the impact of material placement on weighing accuracy (e.g., placing a 10kg reagent bottle without causing sensor damage).
  • Power Failure Protection: A built-in backup battery (optional) maintains the operation of core components (sensors, control system) for ≥2 hours after a power outage, ensuring weight data is not lost and compartments can be unlocked to retrieve urgently needed materials.

Applications

  1. Electronics Manufacturing
    Suitable for storing and managing small electronic components (e.g., resistors, capacitors, microchips) in SMT production lines. The ±0.2g accuracy ensures accurate counting of tiny components (e.g., 0.1g chips), and real-time inventory updates prevent production line downtime caused by material shortages. Typical customer: A semiconductor component factory in East China (uses 30+ cabinets to manage 500+ types of components).
  2. Chemical & Pharmaceutical Industry
    Applied in chemical labs or pharmaceutical workshops to store reagents, catalysts, or pharmaceutical raw materials (e.g., 10g antibiotic powders, 500g chemical solvents). The corrosion-resistant stainless steel weighing platform and sealed compartments (optional) prevent material contamination, and weight-based inventory ensures compliance with GMP (Good Manufacturing Practice) standards. Typical customer: A Grade-A pharmaceutical manufacturer in North China.
  3. Food Processing
    Used in food factories to manage small-batch additives (e.g., food coloring, preservatives) or high-value ingredients (e.g., 200g truffle powder). The high-precision weighing prevents overuse of additives (ensuring food safety) and reduces waste of expensive ingredients. Typical use case: A high-end bakery reduces additive usage errors to zero after adoption.
  4. Scientific Research Laboratories
    Suitable for university or enterprise R&D labs to store experimental materials (e.g., nanomaterials, biological reagents, precision alloys). The accurate weight recording supports reproducibility of experiments (e.g., ensuring 5g of a certain reagent is used in each test), and abnormal weight warnings prevent unauthorized removal of sensitive materials. Typical customer: A material science lab at Zhejiang University.
  5. Automotive Parts Workshops
    For managing small high-value auto parts (e.g., precision bearings, sensor components) or consumables (e.g., special lubricants).
