Dispensing applications for mobile phone back covers: How do five-axis dispenser and piezoelectric jet valve apply adhesive to mobile phone cases?
The key to dispensing adhesive onto the back cover of a mobile phone lies in addressing the precision challenges posed by 3D curved surfaces and ultra-narrow bezels. Traditional three-axis dispensing equipment struggles to meet these requirements, while the combination of a five-axis dispensing machine and a piezoelectric jet valve is the mainstream solution to this problem. Simply put, the advantages of this system are: five-axis linkage allows the dispensing head to “point and shoot,” the piezoelectric jet valve ensures the adhesive reaches the target area “fast and accurately,” and the vision system ensures the entire process is “flawless.” Core Feature 1: Five-Axis Dispensing Machine – Achieving Precise Trajectory on 3D Curved Surfaces The five-axis dispensing machine adds an A-axis (flip) and a C-axis (rotation) to the existing X, Y, and Z linear axes, enabling the dispensing valve to always be perpendicular to the workpiece’s cross-section or maintain the optima...
