Challenges in Hole Detection

Hole Detection

In the production of paper, films and even sheet metal strips, the quality of the endless materials must be continuously checked. Failure to detect holes or cracks in time can lead to serious consequences, such as impaired product quality, damage to the machine, but also safety risks.

Solution
  • Retro-reflex sensors for transparent objects
  • Ultrasonic distance sensors
  • 2D/3D profile sensors

Quality Control of Objects in Holes

The quality control of objects in holes ensures that, for example, a thread is present inside a sleeve to ensure the quality standard in further process steps.

Solution
  • Reflex sensors with background suppression
  • Triangulation laser distance sensors

Detection of Objects with Holes

The detection of perforated objects, such as perforated sheets, grid boxes or printed circuit boards, poses a particular challenge for sensors. Sensors with an inadequately sized detection area could perceive the non-continuous surface of the object as interruptions or errors and thus generate erroneous signals.

Solution
  • Retro-reflex sensors with light band
  • Ultrasonic distance sensors

Measurement of Holes

When industrially manufacturing components or other objects, such as body parts, holes must be drilled. Before the parts can be joined together, it must be ensured that the holes have the exact dimensions so that the screws fit perfectly into the holes.

Solution
  • Vision systems
  • Smart cameras

Look Through a Hole

A major challenge in industrial production environments is the limited space for installing sensors. In conveyor lines, for example, the sensors look at the conveyor belt through holes in the side walls to detect passing objects.

Solution
  • universal retro-reflex sensors
  • Fiber-optic sensors
  • Energetic reflex sensors

Application Areas of Hole Detection

Presence Check for Screws and Nuts

Challenge: 
After the robot-controlled screwing process of body parts, it must be ensured that all screws and nuts are correctly installed in order to ensure the quality of the assembled body parts and to immediately detect faulty screws.

Solution:

Measuring the Indentation Diameter

Challenge:
To ensure the quality of the punching process in the automotive industry, it is necessary to precisely measure the diameter of the resulting indentations. Incorrect or inaccurate measurement can lead to quality issues and increased waste.

Solution:

Hole Inspection of Battery Covers

Challenge: 
When manufacturing battery covers, one challenge is precisely monitoring the punched holes. Fiber-optic sensors enable reliable and fast identification, ensuring quality for further processing.

Solution:
