Problems solved by technology

Since the glue filling machine uses a cylindrical rotating rod to inject glue, due to the limitation of its inherent mechanical structure, the gap between the base that can rotate the cylindrical rotating rod and the cylindrical rotating rod is very small. Large, and the gap accuracy is difficult to control, which also affects the uniformity of the injected glue

Abstract

The invention is concerned with the glue filling machine and the glue filling method for the light-emitting diode, it includes: the engine block (-) with the blanking hole (-) under the storing hole (-); the piston gear (-) connecting with the power source (-); the storing hole (-) attaches with the piston gear (-) where the opening on the side of the engine block that connects with the flow entering hole; there-into the flute (-) and the canal (-) below are in the valve board (-)on the side of the engine block; the valve board controls the operation by moving to the storing hole (-) of the flute (-) that than detaches with the canal leading the connection between the valve board (-) and the flute (-); or moving backwards to detach the storing hole (-) with the flute (-) of the valve board (-) that leads the connection between the canal (-) and the blanking hole (-). The invention insures the equality of the LED glue filling partly and improves its quality and its productivity.

Description

Technical field [0001] The invention relates to the technical field of electromechanical integration, in particular to a method for uniformly pouring glue on LEDs, and a corresponding glue pouring machine using the method.
