  • Publication number: 20230420406
    Abstract: One embodiment of the present invention discloses an intelligent dispensing adjustment system and the method thereof. The system can dynamically detect the fluid dispensing amount of a fluid dispensing unit via a calculating unit having an intelligent dispensing mechanism and keeps monitoring the dispensing situation of the fluid material so as to automatically adjust the fluid dispensing amount of the fluid dispensing unit. The system can adjust the fluid dispensing amount of the fluid dispensing unit by obtaining the information of the state of previously dispensing the fluid material via a closed loop, which can solve the problems, of prior art, that the defects of products may be incurred because the state of the fluid material is hard to control (e.g., the fluid material is insufficient or overflows).

  • Publication number: 20230405629
    Abstract: The present invention provides a dispensing adjustment system, which includes an optical measuring unit, a calculating unit and a glue dispensing control unit. The optical measuring unit measures a glue to obtain a Nth 3D glue signal or a Nth 2D glue signal. The calculating unit receives the Nth 3D glue signal or the Nth 2D glue signal to obtain the volume or the weight of the glue, and compares the volume or the weight of the glue with a default glue value. 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 for the glue dispensing control unit to adjust the glue supplied thereby according to the Nth glue dispensing adjustment signal. The invention can solve the problem that the glue is insufficient or overflows in order to improve the bonding quality.
