However, for thickness gauges (Song Huaxiong, Zhang Yun, Song Lan, et al. Laser online thickness measurement vibration analysis and precision optimization [J]. Semiconductor Optoelectronics, 2021, 42(1):6), the different thickness gauges There is also a large difference in accuracy; thickness gauges with higher accuracy tend to be more expensive
Each foil machine is equipped with a high-precision thickness gauge, which is a heavy economic burden

The invention discloses a method and a system for measuring the longitudinal scale uniformity of an electrolytic copper foil, and a crude foil engine, and belongs to the technical field of new energy automobile power battery electrolytic copper foils. The device is technically characterized by comprising a liquid inlet copper ion concentration sensor, a liquid inlet flow sensor, a liquid outlet copper ion concentration sensor, a liquid outlet flow sensor, a controller and a display screen. According to the electrolytic copper foil longitudinal scale uniformity measurement method and system and the crude foil engine, a thickness gauge can be replaced to a certain extent; meanwhile, based on the scheme of the invention, the surface density difference of the copper foil under any longitudinal scale can be reflected, and the quality measurement and control of the index of the surface density difference of a copper foil production enterprise are facilitated.
Description
technical field [0001] The invention relates to the field of electrolytic copper foils for power batteries of new energy vehicles, and more particularly, to a method, a system and a raw foil machine for measuring the uniformity of longitudinal dimensions of electrolytic copper foils. Background technique [0002] The uniformity index of electrolytic copper foil is one of its product quality control indicators. The research on the uniformity of copper foil has always been the focus of various manufacturers. [0003] The applicant conducted a search on "copper foil, thickness and uniformity" in HIMMPAT and CNKI, and the main research results are as follows: [0004] Document 1: CN111763963B discloses a copper foil thickness uniformity treatment method and a copper foil surface treatment method. In this paper, the copper foil is divided into N parts horizontally, and the thickness is measured by a thickness gauge. Copper plated. [0005] Document 2: CN111304699B discloses an...
