Research and Application of Variable Working Conditions Control Method for QR Code Scanner in Ultra-High Speed Packaging Machine

To address the issue of low accuracy in reading small box QR codes during the variable working conditions of ultra-high speed cigarette packaging machines, a variable working conditions control method for QR code scanners has been designed. This method adjusts the scanning parameters of the QR code scanner based on the machine's speed and the acquired QR code images, adapting to the real-time changes in equipment speed and working conditions. Fundamentally, it enhances the effectiveness and stability of the QR code scanner's information retrieval, improving the stability of the precise association system for QR code information. Results show that the reading accuracy can reach 99.99%, which is an increase of 3.94 percentage points compared to traditional parsing control methods. This technology can provide support for enhancing the stable operation of the QR code association system in ultra-high speed cigarette packaging machines.
