The fully automatic flow test bench is loaded by a robot. There are drawers for 4 pallets (2 pallets for each EDM machine. 1 pallet for loading and 1 pallet for unloading). The Sonplas machine is located between two EDM machines.
The nozzles are automatically loaded from the pallets and positioned in front of the camera which checks the data matrix code. Thereafter, the blanks are loaded onto the respective EDM machine shuttle. The eroded nozzles are removed from the shuttles and are taken to the rotary table. If needed, the nozzles can be turned by a turning station.
The rotary table includes a blow out station and a measurement station. The measured nozzles are loaded back into the respective pallet for unloading. Reject parts are dropped into scrap boxes or two suspect rails.
Production results are stored in a database. The test plans, in which the different parameters are stored, are also located in the database and can be edited by the user.
All flow test results are being sent to the respective EDM machine for production quality optimization.
