SEALANT COATING DEVICE AND DISPENSING METHOD THEREOF

摘要

The present invention provides a sealant coating device having a sealant receiving chamber and a nozzle formed on a lower portion of the sealant receiving chamber. The sealant coating device further has a heating device, and the heating device is installed around the sealant receiving chamber for heating a sealant material filled in the sealant receiving chamber. The present invention further provides a dispensing method of the sealant coating device, which has the following steps of: obtaining time during the sealant material stays in the sealant receiving chamber; calculating a target temperature of the sealant material according to the obtained time and a desired sealant viscosity value; heating the sealant material to the target temperature. The advantages of the present invention are to use the heating device to lower the sealant viscosity based on the characteristic of the sealant viscosity varied with the temperature. In a case that the sealant material stays in the sealant receiving chamber a period of time to cause the raise of the sealant viscosity, the heating device can be automatically started to lower the actual sealant viscosity to constantly keep in the desired sealant viscosity.
