Online detection method and system for continuous vacuum coating of stainless steel coil

Abstract

The invention provides an online detection method and system for continuous vacuum coating of a stainless steel coil. The method comprises the following steps that a to-be-machined stainless steel coil is uncoiled to form a continuously-conveyed stainless steel band; the stainless steel band is conveyed into the coating chamber for vacuum coating; the coated stainless steel band is conveyed out ofthe coating chamber and rolled to form a finished stainless steel roll; when the stainless steel band is conveyed out from the coating chamber to the winding chamber, an LAB detector is used for detecting the color value of the surface of the transmitted stainless steel band in real time, the detection result is fed back to the master control system, the master control system judges whether the film layer on the surface of the steel band meets the set requirement or not according to the LAB value, and if not, the master control system adjusts the coating parameters in the coating chamber according to the LAB value. The method is used for controlling the color of the stainless steel surface film layer to be stable and uniform in the continuous film coating process of the continuous stainless steel coilvacuum film coating device, control is reliable, and the obtained whole coilof stainless steel surface film layer is good in color stability and uniformity.

Description

technical field [0001] The invention relates to the field of stainless steel vacuum coating, in particular to an online detection method and system for continuous vacuum coating of stainless steel coils. Background technique [0002] The existing stainless steel coil vacuum coating production line is mainly aimed at the production mode of single stainless steel plate, which requires a lot of manpower to hang and take out the plate. Since the existing production method is single-sheet production, vacuum extraction, heating, and color plating are required for each production; due to repeated vacuum extraction, it will have a great impact on the performance of the same batch of products produced , cannot guarantee the stability of product color, film layer, and various properties. [0003] In addition, the existing stainless steel coil vacuum coating technology wastes a lot of manpower and material resources in the production process, the production efficiency is low, the prod...

Problems solved by technology

Since the existing production method is single-sheet production, vacuum extraction, heating, and color plating are required for each production; due to repeated vacuum extraction, it will have a great impact on the performance of the same batch of products produced , cannot guarantee the stability of product color, film layer and various properties

[0003] In addition, the existing stainless steel coil vacuum coating technology wastes a lot of manpower and material resources in the production process, the production efficiency is low, the product quality is unstable, and it is impossible to truly achieve mass production.

The existing production method consumes a lot of target materials and electric energy, the utilization rate of materials is low, the production cost is high, and the product quality is unstable
