Analysis of Screws

The challenge for K|Lens

The quality control and sorting of screws presents manufacturers with a number of complex challenges that can have a negative impact on efficiency and product quality. These challenges highlight the need for an automated and efficient inspection solution that enables precise and reliable quality control of screws.
Multiple sources of error

There may be incorrect screw types, foreign objects such as stones, wood or metal parts as well as defective parts in a production batch. This high variance in the errors that occur requires comprehensive quality control with many different requirements.

Specialized inspection stations with separation

The use of numerous specialized inspection stations with different hardware and software leads to a high level of effort during setup and retrofitting. The test stations rely on the exact separation and positioning of the screws. This easily leads to blockages and misclassifications, especially in the case of defective or non-standard parts.

Inefficient inspection processes

Conventional inspection methods often lead to a high proportion of good parts being incorrectly rejected, which increases production costs. To reduce this pseudo scrap while maintaining quality, multiple inspection passes are often necessary, which increases production time and the risk of damage to the screws.

The solution from K|Lens

Our K|Lens light field sensor, paired with our proprietary Multiview AI, sorts parts on a conveyor belt with exceptional efficiency. The camera captures images in sync with the belt movement and inspects each batch for defective parts and foreign objects. Our system reliably identifies non-conforming parts with rotation-invariant defects and can be adapted to new types with minimal training.

System used

Our batchSORTING system specializes in the sorting of mass-produced small parts of low component value and is therefore the ideal basis for screw inspection.

Specific design of the components / structure / extensions

Highly innovative sensor technology

Our Light Field Lens HighRes provides precise image data, adapted to the width of the test strip and resolution required for defect detection.

UI

A customized graphical user interface (GUI) visualizes incorrect bolt types, foreign parts and all specified defects. This enables operators to check the inspection results intuitively and efficiently.

Robust evaluations with multi-view AI

Customized data curation and Multiview AI training provide a reliable Multiview AI model to analyze the screws. Our AI models are specially trained to detect and differentiate between certain types of defects. The AI analyzes all screws in the image area simultaneously and reliably, even with closely positioned components.

API

The entire inspection system is seamlessly integrated into existing production lines without affecting the production flow. The use of APIs means that data is transferred and processed in real time, enabling an immediate response to detected defects.

Customer Benefits and ROI

Cost savings and ROI

Reduction in process costs

Automated control is faster and more efficient than manual control by employees and requires fewer personnel. This significantly reduces process costs.

Low pseudo rejects

The AI-supported analysis minimizes false alarms and reduces the proportion of incorrectly rejected good parts. This leads to considerable cost savings by reducing material waste and rework.

No retrofitting

The system is flexible and can be used for different types of screws without complex retrofitting. This saves time and costs during production changeovers.

Optimization of production processes

The detailed inspection data allows manufacturing processes to be optimized. This increases efficiency and reduces production costs.

Defense against warranty costs

The retention of inspection data reduces the costs of traceability and warranties.

Increased productivity and throughput

High throughput

Compared to conventional individual inspection of each screw, the system enables up to a 20-fold increase in throughput. This leads to a significant acceleration of the production process.

Inline capability

The system can be seamlessly integrated into existing production lines, enabling continuous and automated quality control. This enables 100% control of the products during the production process.

Improved efficiency and productivity

Reliable detection of defects

The K|Lens light field sensor and multi-view AI enable precise detection of incorrect screw types, foreign objects and rotationally symmetrical defects. This ensures high product quality and minimizes the risk of defects in end products. As screws are often used in fully automated processes and even small errors can lead to downtime, you can ensure customer satisfaction with reliable quality control.

No clogging of feeders

AI-supported analysis can analyze the screws while they are still on the conveyor belt. This eliminates the need for separation, which can lead to blockages.

Flexibility and adaptability

One system for all screw types

The system can be adapted to new screw types with minimal training. This enables flexible and efficient quality control for changing production requirements.

User-friendly GUI

The customized graphical user interface (GUI) visualizes all specified defects. This allows operators to check inspection results intuitively and efficiently.

Seamless integration

API integration

The entire inspection system is smoothly integrated into existing production lines without affecting the production flow. Through the use of APIs, data transfer and processing takes place in real time, enabling an immediate response to detected defects.
