With the arrival of the 5G era, the PCB industry has ushered in a golden era and developed rapidly.Electronic products on the PCB quality requirements are also getting higher and higher.
Printed circuit board (PCB), also known as the "mother of electronic products", plays an important role in supporting and interconnection in electronic products, and can reflect the development speed and technical level of the electronic information industry in a country or region to a certain extent.In the current PCB production line, the traditional manual detection method of PCB has disadvantages such as low efficiency, missed detection, misjudgment and uneven quality, and defect automatic detection has become an inevitable trend of industrial development.
Application of AI in all links of PCB
In this issue, Akusense will share the application plan of a recent project —— of minzhi on OCR recognition in the PCB industry.
1. The product is PCB board, so the characters on the PCB board should be identified, the serial number is bound to the detection result of the hole inspection machine, sorted to the mechanical arm for good / bad classification, and product traceability
2. Product size is 600mm * 600mm
3. Speed needs to reach 2 seconds / slice
☆ Scheme Highlights ☆
1. High detection efficiency
The scheme is compatible with all kinds of PCB boards, with CT<100ms and="" the="" accuracy="" rate="" of="">99%, greatly meeting the needs of customers. Products from sampling inspection to full inspection, effectively solving the demand of product traceability.
2. Fool-type operation
All the hardware modules are integrated, and most of the operation process is simplified. The operator can let the equipment run without technical background and simple operation, without opening the third-party camera setting software, simple operation can make the equipment run, namely immediately, and the identification results are visualized.
3. Fast response speed
From customer demand proposal to product deployment, the whole process is completed within 7 days
4. Low power consumption
The scheme adopts a visual controller, which is 90% less power consumption than the industrial control machine, achieving low-carbon production
☆ customer revenue ☆
After the project is delivered on the ground, the quality jump from sampling inspection to full inspection is realized, and then the optimization of the production structure is completed, which greatly reduces the uncertainty and cost pressure brought by manpower. The specific income performance is as follows:
1. Reduce manpower input
Optimized personnel allocation, customers from sampling inspection to full inspection, the original multiple station personnel adjustment to the review area of 1-2 people
2. Reduce risks
All the produced PCB boards are recorded, and the ability of different batches of PCB boards has the product traceability, which is conducive to the process optimization in the later stage.
3. High efficiency of model replacement later stage
If the later customer needs to replace the PCB board or replace the character serial number, only a small amount of data for model training, you can quickly complete the transformation of the production line.
