Cognex DM302X code reader solution

Scanning object: Door body foam line    
Scanning code attributes:   One-dimensional
code scanning Difficulty: barcode size is very small, door body length is variable
Solution: Cognex DM302X code reader
New effect: automatic code reading rate 99.5%, saving Interpretation of labor costs
: The hardware configuration uses Cognex DM302X code reader , COMPUTAR 25mm lens (since the reading distance varies within the range of 350~600mm, the built-in 10mm liquid lens is not applicable), Cognex large Particle LED light source (coupled with the camera, the code reader can smoothly read the small barcode at the bottom of the door within a certain depth of field), network cables and IO cables, as well as the electric control box and IO controller. Software debugging uses the English version of Dataman5.3.

After using the hardware configured above, through debugging, the effective reading distance can be controlled to 350~500mm, and the depth of field change can be within 150mm. Engineers from Samsung Electronics said, "This way, barcodes that we thought could not be read before can be easily read. We were pleasantly surprised to find that the code reading rate suddenly increased to 95%. When producing the Nagato body, the code reader was Move 200mm backward, and when producing a short door body, the code reader is reset again, so that the code reading rate can reach 99.5%. It not only meets the code reading needs of Samsung Electronics, but also improves the automation rate of the production line. For example, automatic reading The barcode is transmitted to the automatic weighing equipment of the position through the electric control box and IO controller, and then the automatic weighing equipment automatically calls up the SPEC parameters corresponding to the detailed section model through the barcode, and compares the weighing results with the SPEC. If it is within the upper and lower limits, it will be deemed qualified.

[Summary] By applying the Cognex DM302X code reader, inspection positions that originally required manual operation have been automated, saving one employee and personnel costs
