Medical patches are products applying Chinese herbal paste on paper reels and then are bonded with cloth. On average, the use of medical patches per capita is 3 pieces per person per month, and monthly demand is approximately 60 million pieces. The research and development of medical patches is now combined with high technologies to enhance their efficacy, but no automatic removable compact roller systems are in existence, compact roller is installed on the walls of a coater. If this roller has bad surface, the viscosity quality of the product may be influenced. Based on the above, a multi-axis replacement system is under development, this plan intends to develop a highly accurate and stable automatic removable compact roller systems using LabVIEW as the primary graphical controlling software, and in combination with motor-movement adapter. The system is highly precise and stable. The roller can be replaced very quickly. The goal is to improve the yield and output.
