LION TEC’s Photovoltaic Insulating Adhesive Inkjet Printing Equipment: Delivering Process Innovation for PV Manufacturing
Recently, a complete set of photovoltaic insulating adhesive inkjet printing equipment developed by LION TEC has finished comprehensive commissioning and quality inspection. The fully assembled unit has been safely loaded and shipped to a long-term partner’s production line. This advanced industrial inkjet solution is designed to drive comprehensive upgrades for the client’s solar cell insulation manufacturing processes, helping the photovoltaic enterprise cut operational costs, boost overall production efficiency and achieve eco-friendly, low-carbon production goals across the board. As the photovoltaic industry accelerates its shift toward high-efficiency, energy-saving and sustainable manufacturing, traditional production techniques are gradually struggling to meet the increasingly stringent requirements of modern PV cell fabrication, making innovative printing and coating technologies more indispensable than ever.
The core highlight of LION TEC’s solution lies in replacing the conventional green oil thermal curing process with state-of-the-art UV inkjet printing technology, which brings revolutionary improvements to every link of the insulation production workflow. First and foremost, this equipment drastically raises the utilization rate of insulating materials. Adopting mature drop-on-demand piezoelectric inkjet technology, the system precisely controls ink droplet output according to actual production needs. The stable material utilization rate can reach over 95%, a remarkable improvement compared with traditional green oil coating methods. Conventional green oil coating is plagued by excessive material overflow and severe waste, which not only pushes up the recurring procurement cost of consumables but also creates heavy burdens related to waste collection, treatment and environmental disposal. By eliminating such unnecessary waste, LION TEC’s inkjet printing equipment effectively lightens enterprises’ dual pressure of cost control and waste management.
Secondly, the new UV inkjet solution greatly shortens the overall production cycle. Different from the traditional green oil process that relies on prolonged high-temperature baking, this equipment leverages instant UV light curing technology. It completely removes the time-consuming procedures of heating up, maintaining high temperature and natural cooling. Statistically, the total cycle of the entire production process is reduced by 30% to 50%. For large-scale photovoltaic production lines, this time saving translates directly into a dramatic leap in daily output and line capacity, enabling manufacturers to fulfill large order demands more efficiently and gain a stronger competitive edge in the fast-growing PV market.
In terms of printing accuracy and energy consumption, LION TEC’s photovoltaic insulating adhesive inkjet printing equipment also shows outstanding advantages. The device is equipped with high-precision motion control systems and sophisticated ink path management modules, ensuring that the graphic printing accuracy far exceeds the standard of traditional thermal curing processes. It can deliver uniform and precise insulating adhesive coating on the back of back-contact solar cells, accurately covering positive grid lines, negative grid lines and designated insulation areas, which effectively guarantees the insulation performance and operational stability of finished solar cells. Meanwhile, the whole production process operates under low-temperature UV curing conditions, with no high-power heating devices required. This design slashes the overall energy consumption of the production line significantly, perfectly matching the energy-saving renovation demands of modern photovoltaic factories and aligning with the global trend of energy conservation.
Furthermore, the full UV inkjet system achieves zero Volatile Organic Compounds (VOC) emissions, standing out as a typical green manufacturing technology. Traditional green oil thermal curing processes generate large amounts of harmful exhaust gas, forcing PV manufacturers to invest heavily in exhaust gas treatment facilities and go through complicated environmental approval procedures. In contrast, LION TEC’s UV inkjet solution produces no harmful volatile substances during operation. It helps enterprises get rid of environmental pollution risks and cumbersome compliance work, fully complying with the green manufacturing standards and carbon neutrality development goals of the new energy photovoltaic sector.
