NANO SEIMITSU CO., LTD.
Nano Seimitsu world class sorting machines / visual inspection!
Also manufacture and sales of shafts and fastener parts as well!

Appearance sorting machine

Combining advanced image processing and automation technologies, DECSYS visual inspection equipment

Cost advantage (reduction of inspectors) by automating visual inspection, and efficiency improvement by assigning inspectors to different tasks, It also contributes to stabilization of quality and improvement of productivity by eliminating human errors caused by loss of concentration and oversights.

Semi-automatic inspection system SA-C series

Anyone can perform quantitative testing by simply inserting a workpiece!

Learning and optimization of inspection criteria thresholds Easily improves inspection quality by comparing product images with good models. Operators only need to manually insert workpieces. Only the inspection is automated, which reduces costs while eliminating human defect outflow and enabling quantitative inspection. Quantitative inspection is now possible.

Just by putting the workpiece into the inspection unit, Anyone can perform quantitative inspection


No operator visual inspection training required. Camera inspection ensures consistent quality.

Stable detection of "flaws" that are difficult to detect even by visual inspection


Highly accurate inspections can be performed by the multiple imager. (Patented technology)

On a table-top machine that does not require a PLC, Low cost due to semi-automatic operation


No technical knowledge is required to use this system. Motor and lighting control with dedicated software

DECSYS' Only One Technology! Multiple Imager

Automatic sorting machine for appearance of all shaft circumference and both end faces

The industry's best in image processing technology, capable of detecting defects as small as 0.2 mm

DECSYS, the only company that combines image processing and automation technologies, DECSYS is a one-of-a-kind company that combines image processing and automation technologies.

Detects defects such as foreign matter, dirt, scratches, and dents at the level of 0.2 mm square minimum.

Linear visual inspection system

Stable detection of scratches and dents on metal, plastic molding and rubber products

High-speed inspection of linearly conveyed products with up to 5 cameras (1 top camera and 4 side cameras)! Dirt, scratches, and dents are detected without omission.

Applicable to various products such as metal parts, resin molded products, and rubber products.

Ideal for top or side full-surface inspection (Number of cameras: up to 5 cameras)

Because a fixed quantity can be inspected automatically, One person can perform multiple operations with other equipment. Multiple operations are also possible.

Manufacturing IoT Solutions

AI Image Automated Inspection Package

With AI image inspection using Toshiba's unique good quality learning method, Automation of inspection and improvement of inspection accuracy in a short period of time

This solution automates the inspection process at manufacturing sites using AI image inspection technology based on the Good Product Learning method. Good product learning based on Toshiba's proprietary threshold optimization method enables the system to reduce false
positives while preventing defective products from being missed. It reduces the number of workers in the inspection process and contributes to the realization of a new style of manufacturing site in the with-corona era.

Challenges in AI learning methods


Large numbers of good and bad products Collecting and learning from teacher data is time-consuming

Creating a good model and Adjustment of accuracy Highly specialized skills are required

 

Issues in Inspection Equipment


Installation and maintenance on existing lines Installation and maintenance on existing lines is difficult to install and maintain on existing lines

Only good images are used as teacher data Learning with a short period of time and a small number of images

 1 

Reducing False Positives Toshiba's unique good learning method

Unique threshold optimization method for Prevents false positives and Defective products are prevented from being missed

Specialized image input and parameter setting Can be performed on-screen without specialized skills

 2 

Intuitive on-screen Create good models

Creation of good models and verification of accuracy, Verification of inspection results, etc. Easy-to-use GUI provided as standard

No dedicated inspection equipment, so it can be installed in a limited space and requires no maintenance.

 3 

Easily retrofitted to existing lines Easily introduced

No modification of existing lines is required. No modification of the existing line is required, and commercially available equipment such as cameras and lighting can be retrofitted for immediate installation.

Image inspection for on-site use based on Toshiba's technology and know-how

 

Functions provided / Form of provision

● Learning Tools

Good model is created by inputting training images and setting parameters on the screen.

● Good/failure judgment engine

Compares the good model with the image to be inspected to determine whether the product is good or bad.

● Image preprocessing

Performs pre-processing such as position correction of the image to be inspected

● Camera I/F

Receives images to be inspected taken from the camera and passes them to image preprocessing.

● Judgment result display screen

This screen displays real-time and historical results of the good/fail judgment.

The software package for the above functions is available as a subscription-type annual license. Hardware other than software, such as cameras and lighting, is not included in the package. (Individual quotation)

Good learning method / Application examples

Toshiba's unique good learning method

◆ Compare product images with a model of good products learned and optimized for inspection criteria thresholds.

Statistical learning of acceptable threshold values for good products based on variations in images of good products, and judging products that deviate from the threshold as defective.

◆ Threshold optimization method to reduce false positives (*Patent pending)

Detects areas prone to false positives and iteratively trains to optimize the threshold of the good model to prevent false positives from occurring in those areas

Application Examples

◆ Welding inspection at an automotive parts manufacturer

Applied to the inspection of welding, which is considered difficult to inspect without skilled workers due to the variability in workmanship, even for good products.

◆ Automation of visual inspection by inspectors

Automates visual inspections in the inspection process, where inspectors used to perform visual inspections and defect corrections, reducing inspection workload while maintaining inspection quality.
