Process analysis of constant linear speed of lithium battery winding

Lithium battery winding constant speed technology and control solutions. In the future, my country will invest 100 billion yuan to support the development of the new energy automobile industry, which will further promote the progress of the battery winding industry. This article will analyze what is the process of battery winding constant linear speed, important skills and difficulties, system performance requirements and solutions. 1. Preface Do you know? The mobile phone batteries, laptop batteries, camera batteries, DV batteries, and electric vehicle batteries we use are all processed by lithium battery winding machines. There are mainly three types of lithium battery winding machines: square semi-automatic winding machine, square automatic winding machine, and circular automatic winding machine. Here, the square automatic winding machine is first analyzed. Second, the professional vision of battery winding, led by electric vehicles, has become a key support object during the 12th Five-Year Plan period. In 2010, the central financial department and various local financial departments clarified the dual impact measures of heavy subsidies and government support. According to the preliminary plan, my country will invest 100 billion yuan to support the development of the new energy automobile industry in the future. Some ministries are taking the lead in formulating relevant policies to support new energy vehicles. The 'Twelfth Five-Year Plan for Electric Vehicle Technology Development' led by the Ministry of Science and Technology has been formulated and will be officially announced next year at the latest. According to the plan, automobile miniaturization and electrification are two important directions for my country's future automobile development. By 2015, the number of electric vehicles in my country will reach 1 million, and the battery capacity will reach about 1 billion watt-hours. Therefore, my country plans to promote the development of the electric vehicle industry chain, making power lithium-ion batteries, motors, and electronic controls the center of the future. The development of the new energy automobile industry will inevitably bring about the rapid development of battery processing and manufacturing, which will bring huge development opportunities to battery processing equipment companies, and at the same time, to a large extent, it will propose higher standards for existing battery processing equipment. Requirements. Third, battery winding constant speed technology The important technical difficulty of lithium battery winding equipment is how to control the tension of the diaphragm and the electrode plate and the constant speed winding. The quality of the plate tension control directly determines the processing quality of the battery. The tension also directly affects the balance and processing power of the battery winding process. And the tension control is directly controlled. When the battery is wound, if the linear speed of the electrode is stable, the tension will be a stable value. If the linear speed jumps, the tension will jump. The constant speed control of the battery pole piece is particularly prominent in the square, because the shape of the roll type needle is very special, so the center distance between the roller needle and the volume of each point of the periphery is different, and it is an irregular shape, so in order to complete Constant linear speed, the speed at which the needle must rotate, can ensure that the arc at each point is at the same speed this week.
