Vision sensor inspects small features
A vision sensor Checker 232 inspects small features over a wide area, providing reliable inspection results on the fastest production lines, operating at up to 1,500 parts/min.
Doosan's priority is to ensure that each machine is assembled using the right parts and should the need arise, to guarantee that replacement parts used are the right ones.
To ensure each part is identifiable individually, characters containing unique information are engraved on its surface, for example on the body of an engine block.
These codes directly marked on the surface of each part then need to be verified, read and recorded.
Doosan had tried vision sensors before but it was vision technology from Cognex proved to be the only solution capable of 100% accuracy.
The use of vision to identify each part in assembly and feed the information to the company information system is vital to guarantee the production process.
* 100% part traceability in engine assembly - engine assembly involves many components such as engine block, cylinder head, crank shaft, cam shaft, connecting rod with often similar characteristics, making it difficult to distinguish between them.
Doosan Infracore has invested in vision enabling accurate character recognition of information directly marked on the surface of a part.
The acquired data is then logged in the company information system ensuring traceability of the part through the entire production process.
* Easy installation - easy to install and to configure, the Cognex DVT530 vision system ensured the OCR or optical character recognition, reading characters and transferring the data accurately to the destination.
Reliability and accuracy of reading plays the most important role in the production process.
Previous vision sensors proved inaccurate thus yielding unreliable results.
Cognex vision proved capable of providing 100% readability even in difficult reading environments.
The vision system offers the following advantages.
* Automation of the entire production process from robot part picking to assembly.
* Record kept for each part.
* Correct part assembly guaranteed.
* Provides high ROI.
* Ease of use.
