DESCRIPTION OF THE AUTOMATED PROCESS:

The operator loads the galvanic blisters into the input tray, then the robot removes these parts and places them on the carousel, where the surface roughness is checked, as well as the hole in the parts. The second robot then puts them into the customer’s blisters, which the operator inserts into the input tray for the customer’s blisters. Once the blisters are ready, they are stacked in a column and moved to an output conveyor, from which the columns are removed by the operator. 
The machine is designed for one worker, who performs tasks according to the operating manual. The process is controlled by the SIMATIC S7-1500 control system.

According to customer requirements, the processing machine is equipped with product inspection:

  • Checking the surface of the sealing surface – the machine must sort out pieces with defects exceeding the customer specification of Ra 1.6 and Rzmax 10. 
  • Inspection of the entire inside of the product using a camera to detect defects and damage.

Example of defects on the inside of the products:
