North Intelligence’s cell loading and unloading solution丨Helping equipment in the photovoltaic industry reduce costs and increase efficiency

As the cost of solar photovoltaic power generation decreases year by year, while the cost of traditional natural gas, coal and nuclear energy increases year by year, the cost competitiveness of global solar photovoltaic power generation + energy storage increases year by year; at the same time, as global temperatures continue to rise, in order to achieve the goal of reducing carbon emissions Goal, photovoltaic energy, as a renewable clean energy, has become a global investment hotspot.

While the domestic photovoltaic industry chain has achieved considerable development, it is also facing the pressure of reducing costs and increasing efficiency. Therefore, the photovoltaic industry is accelerating its transformation to automation, digitalization, and intelligent upgrading. An excellent overall solution for motion control can greatly improve the production efficiency of the photovoltaic industry, and is more efficient and energy-saving than traditional equipment.

The flower basket conveying system is an important process link in the production of photovoltaic silicon wafers. It is widely used in: texturing/etching automatic unloading, texturing cleaning loading, diffusion quartz boat loading and unloading, automatic basket changer loading, silk screen Scenarios such as printing and loading, automatic etching, graphite boat loading and unloading, and silicon wafer counting. In order to ensure the increasing production capacity and quality requirements, it has become a new trend in the industry to add and modify visual crack & debris detection in such institutions, and to combine dual production lines.

Current system pain points

1. The wiring of the traditional servo pulse control method is complicated, the operation of multi-axis setting parameters is cumbersome, the assembly and maintenance costs are relatively large, and the terminal delivery wiring is prone to errors;
2. Photovoltaic silicon wafers are fragile, and the fragmentation rate of silicon wafer transportation and flower basket handling is high;
3. Rising demand for production capacity.

North Intelligence’s 15-year advanced motion control algorithm and mature function library have been transplanted across the board to easily realize complex motion control, continuous interpolation, industry process algorithms, etc.; launched “control + servo + stepping” for photovoltaic silicon wafer conveying and loading and unloading systems EtherCAT bus motion control solution: can greatly reduce manpower input, reduce development difficulty, improve the operation efficiency of the whole machine, and provide strong support for the intelligent upgrade of solar photovoltaic equipment enterprises.

Solution advantage

1 provincial debugging
The EtherCAT communication method is adopted, the wiring is convenient, and the efficiency of assembly and delivery is greatly improved. The servo is free from debugging, which saves debugging time. The integrated debugging software is simple and easy to use, and the time-efficiency ratio is optimized.
2 save cost
Silicon wafer conveying, pick-and-place materials, and flower basket conveying all adopt BIC’s special control mode, which can effectively reduce the fragmentation rate of silicon wafers, reduce the downtime for debris cleaning, and reduce the overall operating cost.
3 High efficiency
Using the optimization method of North Intelligence, the equipment can achieve a transmission speed of 1500 pieces per hour.
4 High stability
With the software redundancy design and modular design adopted by the equipment mechanism, the stability of the equipment is greatly enhanced, and the loss caused by downtime due to failure is minimized.
5. Universal Codesys development platform
The sustainable codesys platform helps equipment manufacturers to quickly develop and deliver, multi-subroutine, multi-task template framework. Multiple programming languages ​​are reproducible, easy to use, and technology transfer costs zero.
