　　In the future, China will invest 100 billion yuan to support the development of the new energy vehicle industry, and new energy vehicles will further promote the progress of the battery winding industry. This article will introduce what is the battery winding constant linear speed process, the main technical difficulties, and system performance requirements and solutions.

　　I. Introduction

　　do you know? The mobile phone batteries, laptop batteries, camera batteries, DV machine batteries, electric vehicle batteries, etc. we use are all manufactured by LR41 battery winding machines. There are three main types of LR41 battery winding machines: square semi-automatic winding machines, square fully automatic winding machines, and circular fully automatic winding machines. Here we mainly introduce the square fully automatic winding machines.

　　2. Prospects of battery winding industry

　　New energy vehicles, led by electric vehicles, have become a key support target during the 12th Five-Year Plan period. In 2010, the central government and local governments announced dual stimulus measures of heavy subsidies and government support. According to preliminary plans, China will invest 100 billion yuan in the future to support the development of the new energy vehicle industry. At the same time, many ministries and commissions are taking the lead in formulating relevant policies to support the development of new energy vehicles. The "Twelfth Five-Year Special Plan for the Development of Electric Vehicle Technology" 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", miniaturization and vehicle electrification are the two major directions for the future development of China's automobiles. In 2015, the number of electric vehicles in China is planned to reach 1 million, and the power battery production capacity will reach approximately 10 billion watt hours. To this end, my country plans to promote the development of the electric vehicle industry chain, with power batteries, motors, and electronic controls becoming the core of future development.

　　The development of the new energy automobile industry is bound to bring about the take-off of the battery production and manufacturing industry, which will bring significant development opportunities to battery production equipment companies. At the same time, it will also put forward higher requirements for existing battery production equipment to a large extent. .

　　3. Introduction to battery winding constant linear speed process

　　The main technical difficulty of LR41 battery winding equipment is how to control the tension of the diaphragm and pole pieces and constant linear speed winding. The quality of pole piece tension control directly determines the production quality of the battery, and the quality of the tension affects the balance of the battery winding process. Safety and production efficiency also have a direct impact. The tension control is directly controlled by the constant linear speed of the pole pieces during battery winding. If the linear speed of the pole pieces is constant during winding, then the tension will be a constant value. If the linear speed jumps, the tension will also A jump will occur.

　　The control of the constant linear speed of the pole piece is particularly prominent on square batteries. Due to the special shape of the rolling needle, the distance between each point on the periphery of the rolling needle and the center of the rolling needle is different. It is an irregular shape, so in order to To achieve constant linear speed, the winding needle must rotate at a changing speed to ensure that the linear speed at every point on the arc in this circle is the same.
