In the intricate world of precision fastening, the humble washer-fastener assembly (a screw combined with a pre-assembled washer) plays a crucial role. Whether ensuring proper load distribution, preventing loosening, or acting as a seal, the integrity of this bonded pair is paramount.

In today's demanding manufacturing landscape, ensuring the absolute precision and integrity of components like rivet caps is non-negotiable. Even minor defects – a minuscule scratch, a hair's breadth dimensional deviation, or a slight shape irregularity – can cascade into catastrophic product failures, costly recalls, and irreparable brand damage. The relentless pressure for perfection demands solutions beyond traditional manual inspection. Enter the Rivet Cap Optical Sorting Machine: an automated sentinel harnessing the power of light and artificial intelligence to safeguard quality at microscopic levels.

Unitecho’s fully automatic visual screening machines entail variable upfront costs depending on configurations. However, their long-term efficiency and precision often outweigh traditional manual methods, making them ideal for large-scale, high-accuracy manufacturing environments. By strategically selecting models and leveraging technological advancements, businesses can achieve significant cost savings while enhancing product quality.

​Unitecho has achieved a major breakthrough in optical sorting technology, securing two national patents. According to the China National Intellectual Property Administration, the patents include the "Multi-Functional Optical Sorting Workstation" (Authorization No. CN222402392U) and the "Optical Image Sorting Machine with Automatic Material Centering Structure" (Authorization No. CN222402365U), filed in April and May 2024, respectively.

AI vision inspection systems typically require an operating temperature range of 20°C–30°C. High temperatures may cause overheating of electronic components and increased sensor noise, while low temperatures can lead to lubricant solidification or component frost. High-precision devices often require temperature compensation technology or additional cooling systems

​In an era of precision and innovation, the optical sorting machine stands as a beacon of technological advancement. Harnessing the power of cutting-edge optics, these machines redefine the standards of accuracy and productivity in various industries. The art of design meets science as these devices seamlessly integrate sophisticated algorithms with sleek and compact designs.

Automated Optical Screening Device for Six-Sided Flange Bolts The state-of-the-art equipment employs a vibratory feeder to sequentially place bolts onto an inspection platform. Utilizing advanced industrial CCD cameras with high resolution, the system captures a 360-degree image of each bolt for comprehensive examination.

A combination of shims and screws is inspected using an Optical Sorting Machine, a sophisticated piece of equipment designed for high-speed image analysis. High-speed cameras capture clear images of both components, which are then transmitted to a computer system for meticulous processing.

​In the realm of precision engineering, screws and nuts play a pivotal role. However, despite their importance, manufacturing imperfections can sometimes affect their visual appearance. Here's an overview of some common defects that may be observed:

​In today's fast-paced manufacturing environments, the efficiency of tight screw detection and sorting is paramount. Screw sorters, specifically designed for this purpose, have revolutionized the process by significantly boosting productivity and accuracy in the assembly line.
