Anti-breaking foil device, 9μm~20μm copper foil post-processing anti-breaking foil method, post-processing machine

Abstract

The invention discloses an anti-breaking foil device, a post-processing anti-breaking foil method for 9 μm to 20 μm copper foil, and a post-processing machine; it belongs to the technical field of electrolytic copper foil for power batteries of new energy vehicles; its technical points include: the thickness gauge component Include at least 4 thickness gauges, of which at least 2 thickness gauges are set on the left side of the copper foil, and at least 2 thickness gauges are set on the right side of the copper foil; the two thickness gauges distributed on one side of the copper foil are used for It is used to measure the copper foil thickness of the edge and the adjacent edge area; the thickness gauge assembly and the rotation angle sensor are connected to the control system; the control system is connected with the post-processing drive motor assembly; the thickness gauge assembly is arranged in the Between the reel and the first treatment tank. Using the anti-broken foil device, 9μm-20μm copper foil post-treatment anti-break foil method, and post-processing machine of the present application can maximize production efficiency on the premise of ensuring the post-processing safety of 9-20μm copper foil.

Description

technical field [0001] The invention relates to the field of electrolytic copper foil for power batteries of new energy vehicles, and more specifically relates to an anti-breakage foil device, a post-processing anti-breakage foil method for 9 μm to 20 μm copper foil, and a post-processing machine. Background technique [0002] The applicant first applied for "2020101128474 A single machine for anti-broken foil post-processing, production process, control method, and control system", which provided a control method for the anti-broken foil device of the post-processing machine. There is a features such as figure 1 Shown: There are 7 abnormal cross-sections in a certain area (the distance between the cross-sections is less than L), and after the third cross-section, the running speed of the copper foil decreases to V 3 , regardless of the V of the following 4 abnormal sections 适应 is how much, the copper foil has been in accordance with V 3 The speed advances, that is, it ha...

Problems solved by technology

[0003] From the above, it can be known that the scheme proposed in the previous application for "a post-processing single machine, production process, control method, and control system for anti-broken foil" tends to be conservative. , at operating speed V 1 , V 2 It is also possible, however, to run at speeds from V 3 Accelerate to V 1 , V 2 , there will be a short acceleration process, which is not conducive to the safety of copper foil
