Robots in the photovoltaic industry

Time:2012-03-27 14:00

   With the continuous rise of the solar photovoltaic power generation industry, the robot industry has brought great opportunities for development and a bright future. In order to increase productivity, increase flexibility, and reduce costs, major top solar manufacturers have all chosen robot manufacturing technology.


   Nowadays, the use of flexible automated robotics technology has penetrated the entire manufacturing process of the solar photovoltaic industry. From the initial polysilicon ingots to the rapid processing of wafers, and to the final assembly of battery panels and battery modules, flexible automated robot technology has appeared everywhere in the entire process flow. For many start-up solar manufacturing companies, robot suppliers can not only provide them with excellent production equipment, but also can bring them a wealth of production experience and knowledge.


   At present, some large-scale solar energy manufacturing companies in China have adopted robot manufacturing technology in three major production processes of wafer growth, wafer manufacturing, and module packaging in solar cell production.


   In the solar wafer manufacturing process, the wafer needs to undergo a series of chemical treatments. The key to the success of chemical processing is the ability to achieve flexible transfer of wafers between several devices. This process cannot be completed without the assistance of high-speed robots. For production enterprises with a wafer production volume of one million wafers per week, if we use manual operation instead of robots in production, it is impossible to reach the current production capacity and it is impossible to achieve this. Ensure the continuity of production. If wafer processing actually uses manual processing, the production situation cannot be imagined. Very thin solar wafers are very fragile and easily damaged. If it is actually handled manually, the breakage rate will be quite high. Flexible robot technology can be used to solve this problem. At present, the flexible robot technology in the robot production process uses the Bernoulli clamp technology. Bernoulli Clamp Technology is based on the Bernoulli effect, which uses a high-speed air flow to suspend the wafers on a clamp to form a non-contact wafer processing pattern.


   In the solar cell manufacturing process, various large-scale photovoltaic companies have selected a large number of robots of various structures. Among them, the structure is compact, the speed is fast, and three axes and four axes are used in large quantities. They can handle hundreds of wafers per minute. Moreover, with the help of visual technology, the system not only realizes visual guidance, but also realizes real-time monitoring of product quality at the same time. It can easily detect cracks, gaps and other quality problems at any time.


   In the panel assembly process, large-scale photovoltaic enterprise factories have also selected a large number of industrial robots. The robots used in the panel assembly process are mostly large-scale heavy-duty robots. The reason why heavy-duty robots are chosen in the panel assembly process is that the panels themselves typically weigh 30 to 35 pounds. However, the actual production will be affected by the end effect, and the weight will be greatly increased. Therefore, the panel assembly process Must use heavy-duty robots. Due to the complexity of the assembly process of the panel assembly line, there are usually a number of robots working cooperatively, for example, some robots are used for the packaging and fixing of the panel; some are used for the assembly of glass and panels, and different purposes use different types of robots. .


   In the panel assembly process, the flexibility of the robot technology is utilized to achieve timely fine-tuning of the production process. For example, in order to adapt to changes in the solar cell module edge washers, when the head of the robot needs to be modified, the robot program can be simply adjusted by appropriately adjusting it.


   Robotic flexible manufacturing technology is particularly important for the development of emerging industries such as solar power that are just starting up and are yet to be improved. Many technologies and products look perfect during the test and development phase. However, once they are actually transferred to mass production, problems and defects will continue to be exposed. At this time, robot manufacturers and senior robot integrators have become the company's most powerful helpers.


   With the development of society, robots have gradually penetrated into all aspects of industrial production, whether they are used to replace old production models or used in the production and use of emerging product lines. Although some production tasks can indeed choose not to use robots, there are many production tasks that can only be accomplished by robots. In particular, the production tasks that require high speed, flexibility, etc. are even more inseparable from the help of robots. Now.
