Detailed Description
Referring to fig. 1, the utility model provides a foil coating effect detection device, which comprises a detection platform 1 and a detection mechanism; wherein:
the detection platform 1 is horizontally arranged, and a fixing piece for fixing a sample is arranged on the detection platform 1. The detection platform 1 is also provided with a vertically arranged support column 2, the support column 2 is provided with a vertically arranged linear guide rail, and the linear guide rail is provided with a lockable sliding block 8 in a sliding fit manner.
The detection mechanism is arranged on the slide block 8, the distance between the detection mechanism and the detection platform 1 is adjustable, and the detection mechanism comprises a rotating roller 3 which is provided with solvent and used for wiping a sample and a motor 9 used for driving the rotating roller 3 to rotate.
In the specific embodiment, the fixing member comprises a first pressing rod 5, a first connecting plate 4, a second pressing rod 7 and a second connecting plate 6, the first connecting plate 4 is fixed on the detection platform 1, and the end of the first pressing rod 5 is rotatably connected with the first connecting plate 4 through a first rotating shaft. The second connecting plate 6 is fixed on the detection platform 1 and is parallel and opposite to the first connecting plate 4, the second pressing rod 7 is parallel to the first pressing rod 5, and the end part of the second pressing rod is rotatably connected with the second connecting plate 6 through a second rotating shaft.
The utility model discloses the theory of operation: firstly, sampling, namely preparing a foil material to be subjected to solvent-resistant wiping, cutting the foil material into a shape capable of being placed on a detection platform 1, and ensuring that a first pressure lever 5 and a second pressure lever 7 can be pressed on the foil material; then, checking the equipment tool, mainly observing whether the rotating roller 3 in the equipment tool is good, and ensuring whether a solvent exists on the rotating roller 3, if not, adding the solvent; after the preparation work is ready, a sample is placed on the detection platform 1, the first pressure lever 5 and the second pressure lever 7 are adjusted to enable the foil to be flatly fixed on the platform, and the height of the rotating roller 3 is adjusted downwards to enable the foil to be at the testing height; and then adjusting the time of the rotating roller 3 needing to rotate or the number of turns of the rotating roller 3 needing to rotate, turning on a rotating switch, starting to rotate, and after the rotation is finished, upward adjusting the rotating roller 3 and observing the condition of the foil. If no exposed foil is present on the carbon-coated foil, this sample is said to be able to withstand solvent wiping under the test conditions, whereas if exposed foil is present on the carbon-coated aluminum foil, this sample is said to have poor solvent wiping resistance.
The utility model discloses can also quantify the solvent-fast performance of wiping, can contrast the rank of solvent-fast wiping of two kinds of samples to a certain extent. Since the rotating roller 3 is determined by adjusting the time or the number of turns, the time or the number of turns is divided into a plurality of small units, for example, the time can be divided into 5s as a unit, the test condition is observed after every 5s until the foil leakage condition occurs, the total time is recorded, and the number of turns can be operated in the same way. Therefore, the solvent-resistant wiping can be characterized as specific time or number of turns, relevant data can be better provided in research and development and production, and the state of the carbon-coated layer can be better observed, so that the carbon-coated aluminum foil with better carbon-coated state can be developed.
