Visual inspection works best when it fits into the production process. Cameras capture each part, inspection software checks the image, and the result returns to the workstation for the next action. Industrial computer solutions commonly support this connection between image capture, inspection, and production equipment.

Sihovision develops fanless industrial Mini PCs for machine vision applications in electronics assembly, precision manufacturing, and automated production lines. Installed inside a machine enclosure or control cabinet, it connects compatible cameras, runs the selected vision software, and makes inspection results available to operators and connected device.

1. Application Background

High throughput production environments deploy automated optical inspection to detect surface irregularities, foreign debris, and incorrect mechanical tolerances. Visual inspection stations operate adjacent to robotic arms, stamping machinery, and high speed sorters where space inside control enclosures is strictly constrained.

Edge vision installations face severe plant floor challenges that disrupt typical hardware. Electrical equipment cycling creates voltage ripples, while unconditioned workshop environments expose computing gear to extreme seasonal temperature variations. Vision engineers require resilient, compact compute engines tailored for specific high demand operational tasks:

• High speed surface defect detection on continuous metal stamping lines
• Component placement and solder joint verification on electronics assembly benches
• Real time automated optical code reading and packaging label alignment
• Multi camera robotic pick and place positioning in dynamic sorting cells

2. Solution Implementation

Sihovision's industrial Mini PC serves as the local computing unit within a machine vision inspection station. It can be installed near the camera assembly or inside the machine's control cabinet, depending on the equipment layout.

The system connects compatible cameras, peripheral devices, and the factory network through its available interfaces. Image acquisition and inspection software run locally, allowing production staff to review results at the workstation.

• Intel Core i3-12100 processor with 16GB DDR5 memory: Supports image acquisition, inspection software, and routine data processing.
• Dual Ethernet ports (1Gbps + 2.5Gbps): Provide network connections for compatible vision devices and factory communication.
• 3 × USB 3.0 and 3 × USB 2.0 ports: Accommodate compatible USB cameras, input devices, and inspection accessories.
• DC 9–36V power input: Supports industrial power connections with electrical protection features.
• Fanless design and -20°C to 70°C operating temperature: Suit industrial equipment installations within the specified environmental conditions.

During operation, a sensor detects a product entering the inspection area. The connected camera captures an image and sends it to the industrial computer. Inspection software then analyzes the image according to the configured quality requirements. Results can be displayed on an external monitor or shared with connected production systems.

For installations requiring several cameras, system integrators can configure the available USB and Ethernet connections according to the camera models, image resolution, and inspection workload. Camera compatibility, processing speed, and software requirements are evaluated during system integration to match the production application.

3. Project Benefits

After integrating a fanless industrial computer into the inspection equipment, manufacturers can organize image acquisition, inspection processing, and production communication within a compact local system.

With suitable software and system adoption, the proposed setup can offer:

• Simplified equipment integration: Multiple USB and Ethernet interfaces provide connection options for cameras and other inspection equipment.
• Flexible installation: A compact enclosure fits machine-side computing stations and industrial control cabinets.
• Reduced maintenance requirements: Fanless construction eliminates the need for a cooling fan and related fan maintenance.
• Local inspection processing: Images and inspection results can be processed directly at the production station.
• Production quality traceability: Compatible software can store inspection records for product review and quality management.

The deployment should therefore define what operators see, which records are retained, and how rejected parts are handled. This keeps the project focused on everyday production tasks rather than unnecessary hardware specifications.

4. Customer Testimonials

"We bought this Mini PC for a camera inspection setup at our factory. It was easy to install, and we had no trouble connecting our cameras and getting the software running. It's compact, quiet, and doesn't take up much space in the cabinet. So far, it's been working well for what we need."

“We wanted a small computer for the inspection cabinet, and this setup suited the space. The USB and network connections were useful for our camera and equipment wiring.”

Sihovision-built industrial box PC offers a practical platform for bringing machine vision into an inspection station. Its processor, memory, USB connections, dual Ethernet ports, and wide voltage input provide a basis for connecting compatible devices and running the selected inspection software.

Automated optical verification remains essential for manufacturers striving to eliminate defect escape rates in modern high speed manufacturing environments. Deploying suitable edge vision computing hardware ensures image processing tasks occur with maximum deterministic speed directly at the inspection station.
