Cognex In-Sight Micro 1400 Smart cameras for battery detection

P&g Duracell China Co., LTD in order to ensure the absolute standard of product appearance, the production speed is more than 1200 per minute. 24 Cognex In-Sight Micro 1400 smart cameras were selected for product quality inspection, including battery label position detection, battery label print quality detection, positive battery defect detection (flash detection, photocell detection, over-wrapped edge, under-wrapped edge, stain detection, battery type identification), battery negative electrode defect detection (flash detection, photocell detection, misalignment measurement, over-wrapped edge, under-wrapped edge, stain detection, battery type identification), the detection speed of each battery is below 50ms, detection accuracy is more than 99.7%, ISM1400 perfectly qualified for all detection requirements, won the customer's praise. Cognex became the only smart camera brand designated by the company.

Duracell's photocells move at a speed of 1200 per minute on the production line. When the sensor switch detects the passing of each photocell, the PLC's high-speed counter will send trigger signals to the label position detection camera and the print detection camera at the front end to start the detection. After the detection of these two cameras, the labeled battery is heat-sealed to the next step of positive and negative battery defect detection. Among them, multi-color point light source is used for label position detection and print detection, and multi-color coaxial light source is used for positive and negative electrode defect detection. 4 cameras are equipped with 4 IO modules for product type switching and results output. The detection time of each position is adjusted within 50ms, the unqualified battery will be eliminated by the elimination mechanism, and the qualified product will flow into the packaging link after the test.

In recent years, Duracell Company will upgrade the product inspection technology in the production line every year, and almost all the functions required by customers can be realized through the image processing software platform of Cognex smart cameras, which makes customers' satisfaction with Cognex smart cameras continue to rise, and the competitiveness of Cognex products is also proud of other similar products.
