The invention discloses a
viscous material filling method which comprises the following steps: a wire breaking stage: after filling is finished, a filling needle stays for a first set time T1, then an ejector pin descends to
cut off an outlet of the filling needle, a sealing sleeve ascends to be separated from a container, and meanwhile, the filling needle and the ejector pin ascend to a set position below an inlet of the container and stays for a set time T2. The filling needle stays for the first set time, and the
viscous material at the outlet of the filling needle can continuously flow into the container, so that the accuracy of the filling quantity is improved, and the
wire drawing is reduced. The ejector pin descends to
cut off an outlet of the filling needle, materials in the filling needle are
cut off, the sealing sleeve ascends to damage the vacuum environment in the container, meanwhile, the filling needle and the ejector pin ascend, and the good wire breaking effect can be achieved through the combination of the three means that the ejector pin descends to
cut off the outlet of the filling needle. The filling needle and the ejector pin ascend to set positions and stay for set duration, so that some very fine drawn wires can be automatically disconnected under the action of gravity, and the situation that laminar flow wind outside a container blows away the fine drawn wires and attaches the fine drawn wires to an inlet of the container, and consequently products are unqualified is avoided.
