In today’s fast-paced electronics manufacturing industry, the production process of electronic products is also increasingly complex and refined. In this process, the accurate identification and effective traceability of each component is particularly important. Whether it is a component component or a package module, electronic products need to undergo rigorous testing before assembling the finished product, including functional testing, size and appearance detection. How to replace manual testing, ensure test efficiency and yield, provide mass test fixtures or automation equipment, sensor solutions play an important role.

PXI-5122 Taking the mobile phone shell as an example, the bar code on it not only carries the identity information of the product, but also is an important basis for quality control and process management. To this end, manufacturers usually integrate barcode readers on the device to achieve automated sorting and flow control. For the components that pass the inspection, the system will mark it as “OK” and send it to the next production process; Components that fail the test are labeled “NG” and sent to a dedicated repair or treatment area.

Today, we bring to you the application case sharing of LOI DCR 55 in the electronics industry to efficiently detect the barcode of the mobile phone shell.

Application background and difficulties

− The customer produces test fixture equipment, which is used to press the upper and lower shell of the mobile phone tablet, and scan the bar code on the shell for input and tracking.

− The bar code type is CODE128, the resolution is 0.35mm, the detection distance is about 130mm, and the host communicates with the RS232 serial port.

− The bar code background may reflect light. The bar code reader must be installed on a movable support to adjust the Angle and height. In an industrial environment, the bar code reader may be subjected to electromagnetic interference.
