Specification

Instructions of each module

●  Circulating box packing and warehouse delivering module

For circulating box moving out from the warehouse, loading and unloading transformers, delivering to the working position, empty circulating box placement, and management of the unqualified products circulation box, moving the circulating box into the warehouse and stacking. 

●  Loading and unloading test waiting/ tested transformer module

Use high-freedom robot for loading and unloading the transformers firmly and in high position accuracy. With bar code scan, individually choosing from the circulating box and put into the pallet and individually placement of each transformer after the test.

● Test waiting/tested transformer pallet and delivering module

   For transformer positioning and delivering to each work station

● Appearance inspection module

   For appearance inspection according to the standards

● Withstand voltage and insulation test module

   For insulation resistant and withstand voltage test in the working frequency according the standards

● Error test module

   For secondary coil-to-coil resistant, error calibration and magnetic saturation test

● Tested transformers marking module

Marking of the tested transformer with  un-qualify or qualify mark by the test result.
