The workflow of surface printing equipment Positioning calibration The object is transported to the printing station by a conveyor belt/robotic arm, and a visual sensor (CCD/laser) scans the surface contour to generate 3D coordinate data. The control system calculates the printing path and adjusts the relative position between the printing head and the object (X/Y/Z axis linkage). Printing Execution Transfer printing process: After dipping the adhesive head into ink, press the curved surface and use elastic deformation to adhere to the surface to complete transfer printing (suitable for small areas, high precision). Inkjet process: The piezoelectric nozzle sprays UV ink according to a preset trajectory, and with the help of a rotating shaft, achieves 360 ° full circle printing (with a speed of up to 300 pieces/hour). Curing and Testing UV/LED curing system (wavelength 365-405nm) instantly dries ink to prevent sagging. Automatic detection equipment (such as colorimeter) verifies printing quality, and defective products are automatically removed by .
