Features of Automatic Photovoltaic Junction Box Welding Machine

In the photovoltaic module encapsulation process, the automatic junction box welding machine connects the "heart" of the photovoltaic module (the current generated by the solar cells) to the "external interface" (junction box). ChinTiyan New Energy's PV junction box automatic welding machine, through the deep integration of multi-axis cooperative control and adaptive welding technology, has elevated welding positioning accuracy to ±0.15mm and stabilized the welding yield above 99.95%, setting a new technical benchmark for highly reliable connections in PV modules.

Technological Breakthroughs:

•Intelligent Temperature Control System

Utilizes infrared real-time monitoring and PID closed-loop control to achieve precise welding temperature fluctuation within ±3°C.

Innovative adaptive cooling rate regulation technology effectively suppresses intergranular corrosion at solder joints.

•Multi-Process Compatible Platform

Supports intelligent switching between resistance welding and laser welding modes, fully adapting to junction boxes of different specifications.

Proprietary dynamic compensation mechanism for welding gun pressure ensures consistent welding for busbars with thicknesses of 0.3-0.5mm.

•AI Quality Inspection System

Integrates deep learning algorithms to accurately identify 12 types of defects in real-time, including cold soldering, over-soldering, and misalignment.

Solder joint lifespan prediction model based on big data analysis enables early warning of potential failure risks.

Performance Verification:
•Test data from the latest double-glass module production line shows:

•Single-station welding cycle time reduced to 12 seconds per box.

•Solder joint pull force stability improved to 98.5%.

•Component return rate due to welding issues reduced to 0.002%.

Innovative Advantages:

•Modular design enables rapid production line deployment (<4 hours).

•Supports bidirectional data exchange with MES/ERP systems.

•Reserved 5G Industrial IoT interfaces lay the foundation for smart factory construction.

The equipment will introduce quantum sensing technology to achieve non-destructive testing of the microstructure of solder joints, advancing PV module connection technology towards the "zero-defect" goal，providing crucial technical support for enhancing module reliability.
