How to auto sync the translation keys of with custom multilingual module



I have already the custom multilingual module to be implemented.

For that I used the translation JavaScript. When any screen On Ready() script is executed and keys is added into database.

Also I checked the role here from JavaScript. so for only specific role user script runs. otherwise for other user script not run and keys not created.

Issue :

Sometime the permitted role user is not visited the screen log time. So keys are not created. 

Requirement :

I want to automate this auto sync more.

How I can read the all screen keys values and add into database without visiting the screens?
