Weighing Material Cabinet Design – Small Compartment Cabinet

Weighing Material Cabinet (Small Compartment Version) is a specialized storage and weighing solution developed by HYVODA for “small-sized, micro-quantity materials”—such as electronic components (resistors, capacitors), precision hardware (mini screws, washers), laboratory reagents (micro-scale powders), and medical consumables (small syringes, test strips). It integrates high-density small-compartment layout, ultra-precise micro-weight sensors, and intelligent inventory management to address core pain points of traditional small-material management: “disordered storage leading to loss”, “inaccurate manual weighing of micro-materials”, “time-consuming inventory counting of small batches”, and “difficulty in tracing tiny high-value items”.

Unlike the large-compartment version designed for heavy/bulky materials, this small-compartment model features a compact, multi-grid structure (up to 51 compartments in a single main-sub cabinet combination) with miniaturized weighing units. It focuses on “space-saving, precision measurement, and traceability of small items”, making it an essential tool for electronics manufacturing, precision engineering, scientific research laboratories, and medical device industries to achieve refined management of micro-scale materials.

Features

High-Density Small-Compartment Layout for Space Efficiency
The cabinet adopts a “main cabinet + sub-cabinet” modular design optimized for small-material storage:

Standard Configuration: Main cabinet (21 compartments) + sub-cabinet (30 compartments), totaling 51 independent small storage spaces—far more than the large-compartment version (max. 34 compartments) of the same cabinet width.
Miniature Compartment Size: Single compartment dimensions are customized for small items (standard: 229mm (W) × 360mm (D) × 150mm (H)), fitting micro-materials like 5mm mini screws (in batches of 100+) or 10ml reagent vials (6-8 per compartment) without wasting space.
Vertical Space Utilization: Compartments are arranged in 5-7 layers (vs. 3-4 layers for large-compartment cabinets), maximizing vertical space and reducing floor area occupation by over 35% compared to traditional small-material storage drawers.

Ultra-Precise Micro-Weight Sensing for Tiny Materials
Each small compartment is equipped with a dedicated micro-load weighing sensor (rated load: 8KG) and a ultra-thin stainless steel weighing platform (thickness: 1.5mm), tailored to detect subtle weight changes of micro-materials:

Weighing Accuracy: ±0.1g (for loads ≤1KG) and ±0.5g (for loads >1KG)—accurate enough to track the removal of a single 0.5g resistor or a 2g batch of powder reagents.
Low Minimum Weighing Threshold: The sensor can detect materials as light as 0.05g, avoiding “no-weight recognition” issues for ultra-light items (e.g., 0.1g electronic chips) that ordinary weighing cabinets miss.
Anti-Interference Design: A shielded wire connection between sensors and the control system prevents electromagnetic interference (common in electronics workshops) from affecting weighing precision, ensuring a stable accuracy rate of ≥99.9%.

Small-Material-Specific Safety & Accessibility Design
To address the risk of loss or damage to tiny materials, the cabinet incorporates targeted design details:

Anti-Drop Compartment Edges: Each compartment’s inner edge is raised by 5mm to prevent small items (e.g., mini washers) from sliding out when the door is opened or the cabinet is slightly vibrated.
Transparent Mini-Door Panels: Each compartment uses a 3mm-thick tempered glass door (narrower than large-compartment doors) to allow visual inspection of material stock without opening—reducing the chance of tiny items falling during frequent door operations.
Embedded Label Slots: A small label slot (20mm × 50mm) on each door enables clear marking of material types (e.g., “M2 Stainless Steel Screws”)—avoiding confusion between visually similar small items (e.g., resistors of different ohm values).

Intelligent Micro-Inventory Management & Early Warning
The system is optimized for batch management of small materials, with functions tailored to micro-quantity tracking:

Automatic Batch Inventory: After door closure, the cabinet completes inventory of 51 compartments within 25 seconds by comparing real-time weights with baseline data. It calculates the number of small items (e.g., “Compartment 12: 50pcs × 0.5g = 25g total weight”) and generates a “small-material quantity report”.
Low-Stock Warning for Micro-Batches: When the quantity of a small material falls below the safety threshold (e.g., 10pcs of a certain capacitor), the system triggers a blue LED flash on the compartment and sends a restock alert (e.g., “Replenish Compartment 8: Capacitors <10pcs”)—preventing production delays caused by running out of tiny but critical components.
Abnormal Micro-Weight Alert: If the weight changes by less than 0.1g (indicating possible “micro-theft” of a single chip) or fluctuates repeatedly (suggesting material spillage), the system locks the compartment and logs the event for traceability.

Compact & Durable Structure for High-Frequency Use
Despite its small compartments, the cabinet maintains structural durability to withstand high-frequency access (common in small-material management):

Reinforced Compartment Dividers: Uses 1.0mm-thick cold-rolled steel dividers (instead of plastic) to avoid deformation from frequent opening/closing of small doors or accidental impacts (e.g., knocking the cabinet with a toolbox).
Miniature Heavy-Duty Hinges: Each small door is fitted with a mini stainless steel hinge (load capacity: 2KG) to prevent sagging—even with 100+ daily openings (typical in electronics assembly lines).
Dust-Resistant Seals: A thin silicone seal around each door edge prevents dust accumulation on small materials (e.g., precision chips) that are sensitive to contamination—extending material service life by 20%.

Multi-Modal Identification Adapted to Small-Material Scenarios
The cabinet supports face recognition, fingerprint/vein recognition, and IC card recognition—with features optimized for environments where small-material management is critical:

Fast Recognition Speed: Face/IC card recognition takes ≤0.8s, minimizing waiting time for operators retrieving small materials in high-frequency assembly scenarios (e.g., SMT production lines with 100+ daily material accesses).
Gloved-Hand Compatible: Fingerprint recognition supports light glove use (common in cleanrooms for electronic components), avoiding the need to remove gloves and reducing contamination risks for sensitive small materials.
