Low-latency trigger syncGood vs. Defective
Multi-grade supportAnti-Duplicate
Single count per item4-Stage Synchronized Inspection Workflow
From sensor entry to mechanical sorting, every microsecond is timed to ensure flawless product separation.
1. Sensor Detection
An optical proximity sensor identifies when an apple reaches the inspection zone and commands the conveyor sequence.
2. Optical Capture
The camera captures high-resolution imagery under controlled lighting to eliminate glare and shadows.
3. AI Classification
YOLOX isolates the fruit and ResNet18 classifies surface defects, rot, blemishes, and grading metrics in real time.
4. Microcontroller Action
The classification result triggers an Arduino-controlled diverter gate or pneumatic solenoid for automated sorting.
Commercial Hardware & Intelligence Capabilities
Turnkey engineering encompassing mechanical conveyance, camera rig enclosures, embedded logic, and deep learning.
Conveyor-Belt Design & Integration
Custom fabrication of motorized conveyor chassis, variable-speed motor drives, guide rails, and food-safe belts.
Camera & Sensor-Zone Setup
Calibrated industrial optics, shadow-free uniform illumination, and photoelectric triggers for precise optical timing.
Apple Detection & AI Quality Classification
Deep convolutional neural network trained on thousands of samples to differentiate surface scabs, rot, and prime grades.
Microcontroller & Hardware Control
Low-latency firmware handling motor start/stop cycles, sensor interrupts, reject solenoid actuation, and serial telemetry.
Anti-Duplicate Object Tracking
Algorithmic tracking preventing identical fruit from duplicate classification during conveyor micro-vibrations or pauses.
End-to-End Assembly & Commissioning
Full validation covering mechanical alignment, electrical schematics, software integration, and batch throughput testing.
Where Machine Vision Sorting Adds Value
Customizable for fruit packaging lines, agricultural aggregators, packhouses, and food processing lines.
Apple Packhouse Automation
Automated high-throughput sorting of incoming harvest into premium, commercial, and juice/process grades.
Food Processing & Canning
Inline visual reject of bruised or decaying fruit before entering peeling, slicing, or puree processing lines.
Custom Produce Adaptation
Models, cameras, and mechanical chutes can be tailored for citrus, tomatoes, avocados, and stone fruits.
R&D & Automation Testbeds
Compact laboratory and demonstration conveyors for universities, mechatronics R&D, and robotics testing.
AI Inspection and Conveyor Control
The commercial system combines machine vision with line control. A YOLOX detection stage locates an apple in the camera frame, after which a ResNet18 classifier evaluates the isolated fruit as good or defective. Object tracking prevents the same apple from being repeatedly processed while it remains visible on the conveyor.
The controller interface is designed to send the classification result to the automation hardware. In the implemented configuration, the control output uses a serial connection to an Arduino-compatible controller, allowing the mechanical workflow to respond to the inspection result. Camera position, sensor zone, conveyor sequence, classification model, and reject mechanism can be configured for the required fruit and line layout.
Commercial Configuration Options
Inspection Configuration
Fruit type, acceptable-defect criteria, camera placement, lighting, conveyor size, and inspection sequence can be specified for the production workflow.
Automation Integration
Elexnova can scope the sensor, controller, actuator, data display, and reporting requirements for a complete automated inspection system.
Commercial Solution Details & Adaptation
Is this available as a commercial automation solution?
Yes. Elexnova handles the conveyor fabrication, optical sensors, camera enclosure, microcontroller programming, AI classification pipeline, integration, and on-site testing as a turnkey commercial solution.
Can the system be adapted for another fruit or product?
Yes. A custom solution can be configured with a tailored camera rig, custom-trained classification model, sensor arrangement, conveyor geometry, and sorting actuator for items like citrus, tomatoes, avocados, and packaged goods.
