Embodiment Construction
[0013] The technical solutions of the present invention will be further described below in conjunction with the accompanying drawings and specific embodiments.
[0014] see figure 1 Shown is a soft copper foil cleaning production line, which is used for cleaning the soft copper foil products after heat treatment, so as to perform annealing treatment after cleaning. The cleaning production line includes the following parts from front to back:
[0015] Unwinding device 1, used for unwinding soft copper foil products for subsequent cleaning;
[0016] The degreasing and cleaning system 2 is used for degreasing and cleaning the soft copper foil products after unwinding. In the degreasing and cleaning system 2, the pH value of the degreasing treatment solution is greater than or equal to 12;
[0017] Anti-sticking agent system 3 is used to apply anti-sticking agent on the soft copper foil product after degreasing and cleaning, so as to avoid sticking during subsequent annealing tr...

Abstract
The invention discloses a soft copper foil cleaning production line which is used for cleaning rolled soft copper foil products. The cleaning production line sequentially comprises an unwinding device, a degreasing and cleaning system, an anti-sticking agent painting system and a winding device from front to back; the unwinding device is used for unwinding the soft copper foil products; the degreasing and cleaning system is used for degreasing and cleaning the unwound soft copper foil products; the anti-sticking agent painting system is used for painting anti-sticking agents on the degreased and cleaned soft copper foil products; and the winding device is used for winding the soft copper foil products painted by the anti-sticking agents. Compared with a traditional cleaning production line, the soft copper foil cleaning production line is simplified, the production line path is greatly shortened, and the phenomenon that the copper foil products are broken due to the too long cleaning production line is effectively avoided.
Description
technical field [0001] The invention relates to a cleaning production line of soft copper foil. Background technique [0002] Before the finished soft copper foil rolling is completed and the copper foil product is annealed, it is generally necessary to clean the finished copper foil to eliminate the winding tension of the rolling mill and solve the problems of broken strips and annealed strips. The traditional cleaning production line includes unwinding - degreasing cleaning - pickling cleaning - brush box cleaning - passivation treatment - drying treatment - anti-adhesive coating - winding and other processes. The length of the production line is about 30m, and there are more than ten intermediate rollers. The tension range is 0-10KN, and it is very easy to break the belt. For soft copper foil products, such as rolled copper foil products for lithium batteries, the thickness of the copper foil is 0.035mm-0.05mm, the tensile strength is greater than 140MPa, and the grain...
