Idler wheel forming manufacturing equipment, manufacturing method and micro element manufactured by same

Abstract

The invention relates to idler wheel forming manufacturing equipment, a manufacturing method and a micro element manufactured by the same. The idler wheel forming manufacturing equipment comprises CNCspecial manufacturing equipment with a secondary arc column-- double-knife tower forming design, which is matched with a relevant manufacturing method, so as to manufacture a micro size resistance and current inductor with the IEEE specification within the 0402-4518 specification range by a precise mechanical cutting metal process, and the micro size resistance and current inductor comprises a metal part and an insulating part. The manufacturing method is realized in such a way that a metal strip tightly clings to and is fixed on a lower shaft plane of a first tension rolling shaft along the shaft diameter direction, a main power shaft drives the metal strip to move to the lower shaft plane of the first tension rolling shaft, a forming milling cutter cuts the tension plane of the lower plane of a running metal strip so that a groove is formed at the middle section of the tension plane of the metal strip along the track direction, then, insulants are coated and filled in the groove, and the metal strip which was filled with the insulants is cut, thus the micro size resistance and current inductor without a package is formed.

Description

technical field [0001] The present invention relates to a roller forming manufacturing equipment, a manufacturing method and the produced micro-devices, including a secondary arc alignment-double turret forming center manufacturing equipment, a manufacturing method for manufacturing micro-resistance current sensors, and The micro-sized micro-resistance current sensor made by it. Background technique [0002] Micro-resistor current sensor (Current Sense) may be called "current sense resistor", which is a current sensing electronic component with low resistance as low as 0.0001Ω, which can be used to monitor the working potential in various circuit designs, such as as a battery Charging reminder at low potential, or monitoring operating current or voltage as a circuit protection component is particularly important in the application of energy-saving electronic design. [0003] The micro-resistor current sensor can be made by metal technology, which can be directly made of met...

AI Technical Summary

Problems solved by technology

The size can reach 0201 specifications, but the physical combination state of the metal has changed, and the metal properties are poor. Therefore, as the ambient temperature rises, the resistance value of the micro-resistance current sensor formed by this process will also increase significantly. Therefore, this Although this method can make the components miniaturized, it has the disadvantage of large monitoring errors. There are many doubts when it is used in portable mobile electronic devices, especially high unit price products.
