Reliably Verify 2D Data Matrix Codes

Posted in 2D Datamatrix Reading, Automotive, Cognex, Featured, Flaw Detection, Inspection

The industry now has standards to reliably verify 2D Data Matrix codes. What metrics and methods can you use to assess a mark’s overall quality? By Carl W. Gerst III, Cognex Corporation, Senior Director & Business Unit Manager, ID Products INTRODUCTION Conventional bar codes (such as Universal Product Codes, or UPCs) have gained wide acceptance in applications ranging from checkout and inventory control in retail sales to tracking printed-circuit-board serial numbers in electronics manufacturing. To increase the character content and to store the information in smaller spaces, companies have developed two-dimensional alternatives. One of these, called Data Matrix, adopted as a standard, places square or round cells in a rectangular pattern. Its borders consist of two adjacent solid sides (the “L”) with the opposite sides made up of equally spaced dots. This symbology allows users to store information such...

Verify & Monitor Direct Part Markings

Posted in 2D Datamatrix Reading, Automotive, Cognex, Featured, Flaw Detection, Inspection, Part Identification, Video

The Challenge: The customer wanted to read and verify 2D datamatrix codes that have been laser marked and / or dot peened onto the surface onto machined surfaces. The laser marked codes were not too much of a problem as there are no wear parts on the laser marking system. However, the stylus on the dot peen marker wore and as a result the quality of the code deteriorated. All codes marker need to meet at least a grade C on the AIM-DPM standard. Zero defect assemblies are crucial in the process so every code needs to be successfully read, therefore the code quality must meet the standards. When poor quality code is identified an alarm needs to be triggered to prompt the operator to remove it from the line so that the stylus can be replaced and the...

Saw tooth blade inspection

Posted in Back Lighting, Featured, Flaw Detection, Lighting, Other, Precision Measurement

The Challenge To check saw teeth have been formed correctly, this needs to happen while the blade is moving at a rate of 6m/min. Defects are typically malformed teeth and material cracks. Our Solution We manged to detect all the defects on the saw blades. Additionally, if five appeared consecutively (indicating that there was a problem in the formation tools) the line was stopped. All results are displayed to the operator for analysis, to help determine where the fault...

Windscreen boss position on glass

Posted in Automotive, Featured, Object Location, Precision Measurement, Robotic Guidance

The Challenge: To ensure the position of a boss on a windscreen is positioned correctly. The system needs to detect the pitch and yaw of the boss which is mounted directly on the windscreen. The boss is the mounting point for the rear view mirror and in car microphone, so its critical that it is positioned correctly.  A tolerance of 0.2mm was needed for its position with an angular tolerance of +/- 2 degrees. Our Solution: The positional data of each boss was relayed to the PLC and screenshot of the results was displayed on the screen next to the production line. The accuracy required was achieved with the machine vision inspection system and it saved a lot of time by eliminating the need for manual / operator inspection. The data obtained from each inspection was also tagged to the job to...

Fuse Box Assembly Check

Posted in Automotive, Colour Inspection, Featured, Inspection, Object Location, Presence/Absence

The Challenge: The machine vision system needs to be able to identify which fuses has been used in the fuse box and ensure they are all in the correct place. This needs to happen on the fly while the box is moving on a conveyor at a rate of 5m/min. The system needs to be able to connect to the network and recognise which job is being broadcast so it can ensure the configuration is correct for each instance. Our Solution: A high resolution colour vision camera was installed which detects the fuse types on the basis of their colour. The detected fuses are compared against the expected configuration and incorrectly inserted fuses are highlighted on the operator interface screen. The re-worked fusebox is placed back up-stream and rechecked by the vision...

Spray Bottle Cap Inspection

Posted in Back Lighting, Featured, Flaw Detection, Inspection, Object Location, Other, Presence/Absence

The Challenge: The bottles are being produced at a rate of  60  per minute and travel at 100mm/second. Each bottle needs to be checked to ensure that the applicator has been attached correctly, that the lever is in the right position, and that it is not damaged in any way. Our Solution: The turnkey solution managed to check for the presence of the applicator using a contrast tool, a measurement tool ensured that the position of the lever was correct, and a mixture of various other tools ensured that there were no defects. If a defective bottle was detected, the camera triggered a reject station in order to remove it from the production...

Gasket Impurity Inspection

Posted in Automotive, Featured, Flaw Detection, Inspection, Presence/Absence

The Challenge: Moulded Gaskets travel down a conveyor at rates of up to 10 per second. Each one needs to be checked for any impurities that may have been included during the moulding process. Various different sized gaskets can travel down the same conveyor, so the vision system needs to be able to detect which size it is, and assign the tool checks accordingly. Our Solution: A self-contained turnkey vision system checks all the gaskets to ensure they do not contain any impurities. Any that fail the inspection are rejected from the conveyor and the information is relayed on to operators for them to perform the corrective actions. This helped improved the factory automation on site and reduced human operator...
