How it works

From component card to packed box

BRIZ counts, extracts and packs electronic components. Cards carrying the components are loaded onto the infeed board, from where an electric axis transfers them to the extraction position, where a punch knocks the components out of the card.

The extracted parts drop onto a sliding plate above the packaging box, where they are counted by a camera connected to a PC running software developed in OpenCV. The PLC compares the number of parts detected by the camera with the expected number to verify that no part is stuck or badly extracted - if the count is correct, the sliding plate opens and the parts are gently lowered into the box, while the box conveyor moves back and forth to ensure they are stacked evenly.

As soon as the required number of parts has accumulated in the box, it is conveyed to the position for inserting protective papers and placing the lid. After the lid is placed, the finished box is conveyed onward, ready for shipping.

Control

Interface and control logic

The entire counting, extraction and packing process is controlled by a PLC, which coordinates the infeed magazines, the counting system and the box conveying system.

Physical control station

  • Infeed board for component cards
  • Magazines for boxes and lids
  • Pushbuttons for machine control

Functionality

  • Tracking the number of counted and extracted parts
  • Monitoring the fill level of the box and lid magazines
  • Signaling when box packaging is complete
Installed equipment and features

Technical details

Camera count check

A camera on a PC with OpenCV software counts the extracted parts, and the PLC compares this count to detect a stuck or badly extracted part before it reaches the box.

Separate magazines

Dedicated infeed magazines for boxes and lids allow the machine to run autonomously for longer.

Protective paper insertion

Before the box is closed, the system automatically inserts protective papers over the packed components.
