The device and method for collecting the working currents have the advantage of monitoring the working currents in real time.

Description

technical field [0001] The invention relates to the technical field of working current collection, in particular, to a working current collection device and method. Background technique [0002] With the continuous development and innovation of electronic technology, TFT-LCD (Thin Film Transistor-Liquid Crystal Display, liquid crystal display) is widely used in various electronic products, and the main component of TFT-LCD display is TFT-LCD glass substrate. [0003] The grinding process in the post-processing production process of TFT-LCD (liquid crystal display) glass substrate is mainly to grind the edge of the glass substrate and the chamfering of the four corners. The grinding quality of the glass substrate has a great influence on the later packaging, transportation and deep processing. huge influence. The grinding wheel motor is driven and controlled by a frequency converter, and its working performance directly affects the quality of the product. If the working per...
