How to read the barcode under the EVA film of photovoltaic module lamination?
So in this issue, Xiao Ming will share the performance of Akusense intelligent code readers on site to address the problem of film coating code reading in the manufacturing process of solar cells and modules in the photovoltaic industry~In the production of photovoltaic modules, in order to carry out production control and detection traceability, it is necessary to label the data of each battery module and conduct full process data collection and traceability. And there are also various difficulties in reading codes, such as film distortion, high reflectivity recognition, code quality, ultra small code recognition, large-area recognition, etc., which require the use of professional industrial code reading technology to solve.

Testing requirements
At the photovoltaic module laminating preparation station, it is necessary to identify the barcode at the bottom of the module and upload it to MES
Difficulty analysis:
1. There may be some deviation in the position of the barcode, which has certain requirements for the field of view
2. The surface of the barcode is covered with a layer of EVA film, which is opaque before lamination, resulting in unclear barcode
solution
RCD-AI100-HF06RD
🔹 Compact size, solving the problem of small space installation
🔹 The software operation configuration is simple and easy to use
In terms of automatic parameter configuration, in order to facilitate and ensure that factory workers at each workstation can quickly and easily configure the intelligent code reader system, Meiji has made great design and optimization investment in the automatic parameter tuning algorithm, making equipment debugging easier
🔹 Accurate identification decoding algorithm
The decoding algorithm is the core of barcode recognition. In terms of decoding methods, improvements are focused on the application of photovoltaics: on the one hand, multi-core processing and intelligent search algorithms are introduced in code finding and positioning, greatly reducing the code finding time; Introducing ultra-high resolution imaging restoration algorithm technology to address barcode recognition difficulties caused by frosted materials, aiming to restore barcodes as much as possible to ensure readability
