Dispensing adjustment system and method thereof

A dispensing adjustment method, comprising:

• obtaining a Nth 3D glue signal or a Nth 2D glue signal:
• conveying a Nth substrate to a position under a glue dispensing unit by a conveying unit, wherein N is a constant;
• dispensing a glue to a target position of the Nth substrate by the glue dispensing unit;
• measuring the glue to obtain a Nth 3D glue signal or a Nth 2D glue signal by an optical measuring unit;
• obtaining a Nth glue dispensing adjustment signal:
• performing a calculation according to the Nth 3D glue signal or the Nth 2D glue signal by a calculating unit to obtain a volume or a weight of the glue at the target position of the Nth substrate and comparing the volume or the weight of the glue with a default glue value by the calculating unit, wherein if the volume or the weight of the glue fails to conform to the default glue value, the calculating unit transmits a Nth glue dispensing adjustment signal to a glue dispensing control unit;
• and
• dispensing the glue to a N+1th substrate:
• conveying the Nth substrate to leave from the position under the glue dispensing unit and conveying a N+1th substrate to the position under the glue dispensing unit, adjusting the glue supplied by the glue dispensing control unit according to the Nth glue dispensing adjustment signal and provided the glue for the glue dispensing unit, and dispensing the glue supplied by the glue dispensing control unit to a target position of the N+1th substrate by the glue dispensing unit and then returning to a step of obtaining the Nth 3D glue signal.
