ABSTRACT

An Automatic dispensing machine is an automated equipment that realizes glue positioning, quantification, and timed coating through a high-precision control system. Compared with traditional dispensers, its core feature lies in the precise control of glue output and motion trajectory, which is suitable for small glue dots and complex path operation needs, such as precision instrument assembly, LED chip dispensing, and other scenarios. In order to better optimize the performance of the automatic dispensing system and improve the accuracy and stability of dispensing, finite element analysis theory is used to simulate the physical phenomena, such as glue flow and pressure distribution, in the dispensing process. The influence of the needle inner diameter is more sensitive when the inner diameter is smaller. Longer needles significantly reduce dispensing efficiency due to increased flow resistance.
