Application background

As market competition becomes increasingly fierce, companies are constantly improving production technology and processes while also striving to improve management levels and refinement. As an advanced and mature automatic identification technology, barcode has been widely used in the tracking and management of production plans, raw materials, finished products, processing processes and product quality in the production process of manufacturing enterprises. Especially for consumer electronics products, consumers’ requirements for product quality are increasing day by day, resulting in the electronics manufacturing industry having increasingly higher requirements for product quality traceability.

Applications

A domestic high-tech electroacoustic technology company uses direct parts marking (DPM) to monitor and trace product quality during the production of professional electroacoustic components and electroacoustic assemblies. In view of the characteristics of the production process, work stations and components, it has relatively high requirements for barcode reading equipment, as follows:

1. Barcodes are small in size and high in density. Two-dimensional barcodes are mostly used, which requires equipment with high-density reading performance and the ability to quickly and accurately read two-dimensional codes;
2. Serial communication mode is mostly used, triggered by sensors or serial port commands;
3. The barcode position is relatively fixed, but there may be horizontal or vertical offsets.
4. The code reader is usually fixed on the conveyor line between various workstations or integrated into the equipment. It is required to be small in size and easy to install and fix.

Application configuration solution HM41 series fixed reader

Fixedly installed on various workstations and testing machines of the production line, it is used to automatically read DPM QR codes on components.
The HM41 series fixed reader adopts the world’s leading image scanning engine, which can read accurate two-dimensional barcodes in all directions. For DPM applications of components, it has the following advantages:

1. The reading range is large, and the barcode can still be read when the barcode position is partially offset;
2. Barcode recognition accuracy is high and can read ultra-small DPM codes (2D 4mil) of components;
3. Small size and compact design, easy to be fixed on the production line or integrated into the equipment (49mm×43.5mm×25.5mm);
4. Optional USB or serial port communication, supports multiple triggering methods (automatic induction, constant light, external trigger or switch trigger, serial port command trigger).

Customer benefits

1. Use HM41 fixed reader to replace traditional manual code reading to improve automation level, improve production efficiency and save labor costs.
2. Compared with other foreign brands of the same type, it has more cost-effective advantages.
3. Provide on-site support, provide customized function customization, and enjoy professional and high-quality services.
