Embodiment 1

[0083] Embodiment 1: A detection device for penetration points and pinholes of electrolytic copper foil, including an atomization system (1) and copper foil (2).

[0084] Atomization system (1) includes: atomization system frame, top guide roller (1-1), top drive roller (1-2), bottom guide roller (1-3), bottom drive roller (1-4), shell body (1-5); top guide roller (1-1), top drive roller (1-2), bottom guide roller (1-3), bottom drive roller (1-4), and housing (1-5 ) are fixed on the atomization system frame;

[0085] The top guide roller (1-1), the top drive roller (1-2), the bottom guide roller (1-3), and the bottom drive roller (1-4) are arranged horizontally;

[0086] The housing includes: an upper plate (1-5-1), a lower plate (1-5-2), and a side wall plate (1-5-3), and an opening (1-5-4 ); the shell can be cuboid or cylinder;

[0087] Also includes: a first mobile spray system (1-6), a second mobile spray system (1-7), the first mobile spray system (1-6) includes: sever...

Embodiment 2

[0120] Embodiment 2: The bottom guide roller (1-3) and the bottom drive roller (1-4) in embodiment 1, the copper foil passes through the bottom guide roller (1-3) and the bottom drive roller (1-4). Squeeze, so that the dilute sulfuric acid solution can enter the penetration point and pinhole more fully after being squeezed.

[0121] However, the first embodiment has the following differences. When the equipment is running for a long time, the bottom of the atomization system (1), especially the bottom guide roller (1-3) and the bottom driving roller (1-4) will Agglomerated solution. The purpose of the second embodiment is to solve the above problems.

[0122] The difference from Embodiment 1 is that: the bottom guide roller (1-3), the bottom driving roller (1-4) are cancelled. The lower plate of the shell of the atomization system (1) is provided with an L-shaped plate body (1-8), and a third telescopic power mechanism (1-9) is fixed on the vertical part of the L-shaped plat...

Embodiment 3

[0125] Embodiment three: on the basis of embodiment two, further improvement. Bottom guide rollers (1-3) and bottom drive rollers (1-4) are set under the casing (1-5), that is, the copper foil is initially removed through rubber blocks (1-10) and vertical supports (3) After moisture, then through the bottom guide roller (1-3) and the bottom driving roller (1-4) to make the copper foil run from vertical to horizontal, so that the dilute sulfuric acid solution can enter the penetration point and pinhole; finally in The lower surface of the lower plate of the housing is equipped with a fourth telescopic power mechanism, the other end of the fourth telescopic power mechanism is connected with a compression plate, and the surface of the compression plate is provided with a number of compression rubber blocks at intervals. The width of the rubber block is the same as that of copper. The foils are the same width.

[0126] The way of the third embodiment is that after the copper foil...

Abstract

The invention relates to a detection device for penetration points and pinholes of electrolytic copper foil. The detection device comprises an atomization system (1) and the copper foil (2). The atomization system (1) comprises an atomization system frame, a top guide roll (1-1), a top driving roll (1-2) and a shell (1-5), and the copper foil passes through the top guide roll (1-1) and the top driving roll (1-2) to run vertically instead of horizontally. The atomization system (1) further comprises a first moving spraying system (1-6) and a second moving spraying system (1-7), and a dilute sulphuric acid solution is sprayed to the smooth surface of the copper foil through the first moving spraying system (1-6) and the second moving spraying system (1-7). By adopting the device provided bythe invention, the dilute sulphuric acid can be automatically smeared on the whole surface of the copper foil during detection of the penetration points and pinholes of the copper foil.

Description

technical field [0001] The invention relates to the technical field of electrolytic copper foil, in particular to a detection device for penetration points and pinholes of electrolytic copper foil. Background technique [0002] CN102798638A discloses a method for detecting penetration points and pinholes of electrolytic copper foil, which includes the following steps: (1), sample processing: select a wide water tank as the detection water tank, and trim the copper foil to be tested into one without wrinkles and creases. For the sample, the size of the sample is required to be placed flat in the detection tank; (2), prepare the penetrant: dissolve the dye in alcohol at a concentration of 0.5g / L-5g / L, and fill it into the detection tank; (3) Rough inspection: take the sample and put it into a test tank filled with permeate liquid facing down, leave it for 0.5 minutes to 2 minutes, observe the color points of the permeated rough surface to judge the number and position of perme...
