Device and method for real-time calculation and display of weight of copper foil

Abstract

The invention discloses a device and a method for real-time calculation and display of weight of a copper foil. The device includes a central processor, a clock module, a current sensor for collectingthe output current of a rectifier, an analog-to-digital conversion module, a coder for collecting the rotation speed of a cathode roller, a storage module, a communication module, an operation display screen, a terminal and a power supply; the coder is connected with a rotating shaft of the cathode roller; the current sensor is connected with the current output end of the rectifier; the current sensor is connected with the central processor through the analog-to-digital conversion module; the operation display screen and the central processor are connected; the central processor is respectively connected with the analog-to-digital conversion module and the coder, the central processor is connected with the storage module, and the storage module is connected with the terminal through the communication module. The device in real time calculates the actual weight and error of the copper foil, by comparison with the expected standard weight of the copper foil, the problem of the actual weight of the copper foil is promptly found out, and the scrap rate of the copper foil is reduced.

Description

technical field [0001] The invention relates to the technical field of electrolytic copper foil, in particular to a device and method for calculating and displaying the weight of copper foil in real time. Background technique [0002] The foil machine mainly includes an anode tank, a cathode roll, a motor that drives the cathode roll to rotate, a cathode roll conductive device, a winding mechanism, and a foil machine control system that controls the normal operation of the foil machine. During the production process of electrolytic copper foil raw foil, the AC power is rectified into direct current by a rectifier, and the output end of the rectifier is connected to the foil machine to provide electric energy for the electrolytic copper foil. Under the control of the control system of the foil machine, the motor drives the cathode roll to rotate slowly, and copper foil with a certain thickness is deposited on the surface of the cathode roll out of the electrolysis area.

AI Technical Summary

Problems solved by technology

The output current of the rectifier does not match the speed of the cathode roller, which will cause unqualified quality and weight

However, in the existing foil machine, the quality and weight of copper foil cannot be effectively supervised, and the problems of copper foil weight and weight cannot be found in time. In serious cases, a large number of scraps will be caused, which seriously affects the normal production
