Automotive Gasket Inspection

Vision sensors ensure products are error-free and meet strict quality standards

Companies in a wide range of industries including heavy manufacturing, food and beverage, automotive, electronics, logistics, and transportation rely on vision sensors to perform simple pass/fail inspections that help ensure products and packaging are error-free and meet strict quality standards. By using vision sensors at key process points, defects can be caught earlier in the manufacturing process and equipment problems can be identified more quickly.

How to Solve an Inspection

The first step in any sensor application is to locate, or fixture, the object or feature of interest within the camera’s FOV. Pattern-matching and edge tools do this, detecting even challenging part features such as clear objects, printed text, and rough dimensions which photoelectric sensors cannot. Once the sensor has a reference, it uses pattern, pixel count, brightness, contrast, and edge tools to perform an inspection. The data is compared to the inspection’s specifications, tolerances, or thresholds to make a decision, which is communicated as a binary data output.

By reducing defects and increasing yield, machine vision sensors can help manufacturers streamline their operations and increase profitability. With an array of vision tools and the possibility to perform multiple inspections per target, vision sensors can cut down on cycle time and improve product quality downstream.
