With the transformation of the global energy structure and the improvement of environmental protection awareness, the photovoltaic industry, as an important pillar of sustainable development, has become increasingly prominent in the global energy market. China is a big country in the photovoltaic industry and occupies an important position in the global market. Upstream silicon wafer manufacturing, midstream cell chip manufacturing and downstream formation manufacturing have a global market share of more than 70%. Under the guidance of the dual carbon target, renewable energy represented by photovoltaic energy continues to be optimistic. With the continuous upgrading of technology, the accuracy requirements for production processes and related equipment continue to increase. Improving the production efficiency and product quality of the photovoltaic industry and reducing production costs are the core tasks to promote the development of the industry.
As a supplier of R & D, production, sales and application in the sensor field for many years, Hua Yifeng is committed to finding suitable sensor solutions for photovoltaic industry applications. In the photovoltaic cell production and module production scenario, help industry enterprises to accelerate the transformation to intelligent manufacturing upgrade.
Whether the silicon wafer is detected or not
In the production process of photovoltaic cells, because of its physical characteristics, the traditional inductive proximity switch can not be detected. At the same time, before the silicon wafer is not velvet, it has high brightness, high reflective characteristics, after the velvet, it also absorb light, which makes the conventional photoelectric sensor to a certain extent can not be stable detection. Therefore, the capacitive sensor has become the "ideal choice" to complete the detection task in the production equipment of photovoltaic cells ".
Huayifeng flat capacitive proximity sensor CSF series can not only effectively save installation space due to its flat shape design, but also can stably and effectively detect the position and spacing of the silicon wafer, so as to realize the detection of the silicon wafer, thus ensuring the stable transmission of the silicon wafer in the production process and improving the production efficiency.
Silicon wafer single and double sheet detection
The thickness of photovoltaic silicon wafer is thin (generally only 0.18mm), the material is brittle and easy to break. The USDB series of Huayifeng ultrasonic single and double sheet detection sensors adopts non-contact detection, which can simply, stably and reliably output the single and double sheet state of the silicon wafer without damaging the silicon wafer.
Silicon wafer flower basket detection
The silicon wafer flower basket is a device used to carry monocrystalline silicon wafers and polycrystalline silicon wafers and complete the conversion, cleaning and drying processes of silicon wafers. The effective detection of the flower basket is very important for the next action, such as the automatic loading of silicon wafers in the flower basket to the graphite boat after etching. Huayi Fengfang photoelectric sensor LS200 series can realize accurate positioning and detection of flower baskets loaded with silicon wafers.
silicon wafer grab recognition
In the full-automatic plug-in machine equipment, it is very important to identify the effective grasping of silicon wafers. Hua Yifeng cylindrical capacitive proximity sensor CS series can stably and reliably detect the grasping of silicon wafers.
Trigger basket lifting mechanism
Hua Yifeng cylindrical capacitive proximity sensor CS series, after detecting the silicon wafer at the tongue position, sends a signal to trigger the flower basket lifting structure to move up, completes the insertion of the silicon wafer, and realizes the flower basket lifting structure to move up in the silicon wafer production.
Regional security protection
In the photovoltaic production process, in order to prevent injuries caused by personnel entering the working area of the equipment by mistake when the manipulator grabs the silicon wafer, the H2EL and H2TL series of Huayifeng safety light curtain sensors and the SDS series of safety door lock switches have reliable safety, can be selected and used according to user requirements, and can effectively achieve regional safety protection.
Realize automatic loading and unloading
Huayifeng obstacle avoidance laser scanner RLD-B series is installed on AGV, thus realizing automatic handling and automatic loading and unloading in silicon wafer production.
The photovoltaic industry has entered the fast lane of development under the dual drive of industry needs and favorable policies. As an enterprise in the photovoltaic equipment industry chain, Hua Yifeng will comply with the trend of technological development and continue to introduce new equipment products adapted to the industry and the market, which will comprehensively help promote technological innovation in the photovoltaic industry. it has made positive contributions to the realization of sustainable development and environmental protection.
