Winding machine: As the name suggests, a winding machine is a machine that winds a linear object onto a specific workpiece. Most electrical products need to be wound with enameled copper wire to form an inductance coil, and a winding machine is needed. For example: various motors, fluorescent lamp ballasts, transformers of various sizes, televisions. Mid-periphery and inductive coils for radios, line-output automatic winding machine transformers (high voltage packages), electronic igniter winding machines, high-voltage coils on mosquito killers, speakers, earphones, microphone voice coils, various electric welding machines, etc. Can't give an example one by one, all the coils inside need to be wound with a winding machine. In the textile industry, cotton yarns, man-made winding machine fiber threads, etc. are used to wind various yarn groups suitable for textile machines, and these need to be wound with a winding machine.
Foil coil winding machine is the key equipment for winding low voltage foil coil. Tension control and foil tape correction are the key technologies of foil coil winding machines. The foil ribbon tension of the existing domestic or imported foil coil winding machine is generated by mechanical friction, and its tension is not stable enough, which will cause unevenness of the winding coil tightness, inconsistent DC resistance between the coils, and excessive coil outer diameter. Poor defects. Domestic manufacturers have developed a new type of digital foil winding machine, which uses a DC motor to generate the tension of the foil. Its characteristics are that the tension adjustment is convenient, accurate, and stable. The tension remains the same throughout the winding process to ensure the coil Winding quality. In particular, its tension adjustment range is wide, and it is more suitable for winding thinner foil strips without causing damage to the foil strip ends. In addition, the tension motor is in the power generation state when it is under tension, and the generated electric energy can be fed back to the winding motor or the grid. The friction energy consumption of the frictionless braking tension mode is significant in energy saving. Moreover, the control system will automatically calculate the diameter of the coil on the uncoiler to adjust the output torque of the motor at any time to ensure a constant tension throughout the winding process, which plays a key role in ensuring the quality of the coil. At the same time, the equipment's deviation adjustment system adopts photoelectric analog sensor to detect the edge of the foil tape without contact, and the servo motor is used to dynamically correct the deviation. The system has high precision, fast response, high reliability and high accuracy of deviation adjustment. According to the available information, the equipment technology is already at the world's leading level. The greater the capacity of the transformers used today, the greater the impact on the power grid, and the requirements for their safety are getting higher and higher. The manufacturing quality performance of the transformer requires not only reliable electrical performance, but also more reliable mechanical stability and short-circuit resistance. Most electrical products need to use enameled copper wire (referred to as enameled wire) to be wound into an inductance coil, and a winding machine is needed. For example: various motors, fluorescent lamp ballasts, transformers of various sizes, televisions. The mid-periphery and inductive coils used in the radio, the line output transformer (high-voltage package), the high-voltage coil on the electronic igniter, the mosquito killer, the horn, the earphone, the voice coil of the microphone, the various electric welding machines, etc. can not be cited one by one. All coils need to be wound with a winding machine. In the textile industry, cotton yarn, man-made fiber thread, etc. are used to wind all kinds of yarn balls suitable for textile machines, and these need to be wound with a winding machine.
From the perspective of transformer winding structure design, not all coils can be produced by vertical winding machines. Such as layer structure, multi-spiral structure coil. If this kind of coil is wound by an ordinary horizontal winding machine, it is wound without any pressure in the axial direction, and the gap between the line segments is very large, like a compression spring. The diameter of the coil becomes larger after being compressed, and there is a gap between the coil and the paper tube, which will cause the axial instability of the coil, and the coil may be damaged if there is an axial electromotive force. Therefore, horizontal winding machines with axial and radial compression are widely used in the production of large transformer coils. As the transformer performance requirements are getting higher and higher, the production of general small and medium-sized transformers has gradually begun to use compact horizontal winding machines.
