Height based glue dispensing head closed loop control method and system

The invention provides a height based glue dispensing head closed loop control method which comprises the following steps: location calibration, coordinate transformation relationship establishment, to-be-dispensed area scanning, coordinate transformation and closed loop feedback. The invention further relates to a height based glue dispensing head closed loop control system. According to the height based glue dispensing head closed loop control method, a range unit is adopted to calibrate to establish a height compensation transformational relation of a glue dispensing head, the range unit and an image acquisition device are utilized to collect data in real time during the glue dispensing process so as to form real-time feedback of the glue dispensing head position and realize precise control of the glue dispensing head. The height based glue dispensing head closed loop control method is skillful in concept and rigorous in logic and can be popularized and applied in the automatic gluedispensing filed. 本发明提供基
