Defect and Damage Detection Sensor

Defect and damage detection remains a crucial aspect of modern manufacturing. Identifying problems helps ensure high quality products and prevents financial/reputational damages to the brand.

However, defect and damage detection aren't without their challenges. A good solution must be fast enough to keep up with production and robust enough to work on thousands of different products of varying sizes, types, and designs. This is particularly true when inspecting bulk packages (such as products placed inside boxes for transport).

Furthermore, damage can sometimes affect date and lot coding, which makes traceability nearly impossible. Fortunately, KEYENCE has the solution—defect and damage detection sensors.

How Defect and Damage Detection Sensors Work

KEYENCE has many different types of defect detection sensors. Each has its own unique operating principles, and choosing the right one depends on the application.

For example, CL-3000 Series confocal laser displacement sensors are often used to measure rotor runout in the automotive industry. These sensors transmit light at varying focal distances and measure distance according to the reflected wavelengths. They’re commonly selected for their compact size and stable measurements.

LJ-X8000 2D/3D Laser Profilers are used to find defects like chips, burrs or missing components. They’re also used to confirm product shape and size. These defect detection sensors rely on laser triangulation to measure the distance between the sensor head and the target object.

Lastly, 2D optical micrometers can inspect the dimensions and runout of products by emitting laser light from one end of the device to the other. The passing object creates a shadow that's detected by the receiving element. This shadow is then used to derive measurements of a target object and detect possible defects or damage during production.

Applications of Defect and Damage Detection Sensors

The applications of defect detection sensors are very industry-dependent, as different industries have different defects associated with their products.

For example, defects in the food industry are often related to product size. Hamburger patties often have fixed cook times in fast food establishments. Thicker patties won't cook properly, and thinner patties will burn. LJ-X8000 2D/3D Laser Profilers can check hamburger patty shape and size during production to ensure there aren’t any issues.

Product inspection isn't just related to the food industry. Defect detection sensors can be used for inline inspection for all products across numerous industries.

Benefits of Using Defect and Damage Detection Sensors

Using non-contact defect detection sensors brings multiple benefits, particularly in fast-paced production environments. They can quickly assess the conditions of the target object without touching the material being inspected, which enhances the overall effectiveness of your production process and results in a more reliable product.

Furthermore, these products reduce downtime and lower the costs for scraps and rework. Thus, implementing KEYENCE products brings many benefits to the production process, all of which improve the overall quality of your products and ensure compliance with the standards within the industry in which you operate.
