Cognex DataMan 100 code reader is used for rough surface inspection of automotive workpieces

 BorgWarner encountered challenges when performing code reading operations at the production site. The workpiece is first laser coded on the back, and then code reading and testing is performed after the coding is completed. The detection location is often limited by space, and the installation location is very small. Because there is a certain degree of danger in on-site operations, manual scanning cannot be used. In addition, there is a skylight above the workshop. Especially between 14:00 and 15:00, the sunlight will shine directly on the surface of the workpiece through the skylight, causing extremely serious reflection on the surface of the workpiece.
The surface of the workpiece to be coded is very rough. When light hits the workpiece, it will form light reflections in different directions on the surface. When using an ordinary code reader to capture the image, the QR code will be reflective or blurred, making it impossible to successfully decode it. This results in inaccurate workpiece tracking, which can lead to serious production quality issues.
The DataMan code reader provides personalized solutions to customer needs.
At the site, the operating procedure of the code reader is: when the workpiece travels to the laser coding position, first turn the workpiece over, turn the rough side of the workpiece upward, and perform laser marking. code, and then perform QR code detection; when the QR code cannot be scanned, the judgment information will be transmitted to the PLC through the serial port, an alarm will be issued, and the operator at the next station will be prompted that there is a problem with the workpiece and needs to be inspected; scan After the code is successfully coded, the QR code content information is transmitted to the PLC, which is edited and saved in the industrial computer software to achieve traceability.
The operating procedure of the assembly machine is: first, install the four sealing rings on the clutch and check whether they are in place and whether there are defects; the Cognex camera at this station checks whether the four sealing rings and the circlip are installed in place, and then release the machine. Go to the laser coding station; turn the workpiece over at the laser coding station, and start coding after flipping it into place; after coding is completed, send it to the DataMan 100 code reader station for code reading detection, and transmit the success information to the PLC Process and save; move the workpiece to the next station, and manually detect the polarization degree of the workpiece when it rotates; after passing the inspection, it is oiled and soaked in the oil tank to allow the lubricating oil to completely enter the inside of the workpiece; then the workpiece is taken out and processed at high speed Rotate to remove excess lubricating oil; then package and seal the workpiece, and the assembly of the workpiece is completed.
Since the workpiece moves continuously on the assembly line, there is only a pause at the processing station. In addition, the surface of the workpiece is very rough, and the printed QR code will be deformed, blurred, and damaged after polishing, resulting in reading failure. Faced with many difficulties, the DataMan 100 code reader easily overcame various challenges, accurately read the content of the QR code, and connected to the PLC through the 232 serial port, ensuring the traceability of the workpiece, greatly improving production efficiency and product quality.
The outstanding performance of Cognex products successfully solved the problem
. In addition, BorgWarner's protection of employees is very good. Because the red glare generated by the exposed use of the code reader is relatively harmful to employees' eyes, the technicians specially made a light-shielding cover for protection during installation. This not only meets the customer's safety needs, but also blocks the influence of external light. Ensure the success rate of code reading.
Based on the powerful 2DMax+ decoding algorithm, the DataMan 100 code reader can accurately read QR code information in any environment and low-quality QR codes without changing the processing technology, saving enterprises a lot of time and costs. In addition, the DataMan 100 code reader has a small size and is very suitable for installation in small spaces. It does not occupy an assembly line station and saves space costs. The DataMan 100 code reader also provides USB, 232 serial port and Ethernet communication methods. It is suitable for all communication equipment on the market and has very good compatibility, making it convenient for enterprises to obtain barcode information.
The outstanding performance of the DataMan 100 code reader successfully solved BorgWarner's detection problems and gained the recognition and trust of the enterprise. BorgWarner said that as production increases in the future, it will increase investment in visual systems and code reading equipment. The company's on-site inspection equipment will continue to use Cognex's vision systems and code reading products.
