Description

Technical Field

[0001] The utility model relates to the technical field of sampling devices, in particular to a novel thin film sampling device. Background Art

[0002] When performing performance tests on thin films, a sampling device is required to obtain samples. Our company's patent application number 202020625846.5 discloses a film sampling device, which includes a frame, a first cutting device, a second cutting device, a working plate and a pressure rod. The pressure rod can fix the film on the working plate. The first cutting device can slide left and right along the frame to cut the film into long strips, and the second cutting device can slide back and forth along the frame to further cut the obtained long strip film into samples. In actual use, it is found that the edges of the long strip films cut by the first cutting device are neat, the two sides are parallel and without defects, and the qualified rate of the cut samples will not decrease after long-term use. However, when the second cutting device further cuts the obtained long strip film into several samples that meet the standards, the middle part of the long strip film is far away from the two ends. When it is cut by the second cutter, the side facing the second cutter is easy to roll up or down, so that the second cutter sometimes finds it difficult to cut into the long strip film. After the long strip film is cut, the edge of this end is not smooth. In severe cases, one or more serrations will appear, causing the sample to be scrapped. Utility Model Content

The main body of the transverse cutting knife is a rectangular thin plate with a triangular notch on the thin plate. The two sides of the notch are provided with cutting edges. The plurality of transverse cutting knives are respectively located in a plurality of lower transverse channels 45 and extend upward from the lower transverse channels 45 to above the upper surface of the workbench 4. The upper surface of the workbench 4 is located within the range where the cutting edges of the transverse cutting knives are located (preferably located at the junction of the cutting edges on the two sides of the triangular notch). It also includes a pressing plate 5 detachably connected to the workbench 4, and a plurality of upper transverse channels 51 are provided on the pressing plate 5. When the pressing plate 5 is installed on the workbench 4, the upper transverse channels 51 are used to accommodate the upper part of the transverse cutting knife. When in use, combined with Figure 1As shown, first, the longitudinal cutting device 1 is moved to one end of the workbench 4 and outside the fixed slot 46, the transverse cutting device 3 is completely pushed in so that the transverse cutter is outside the longitudinal channel 411 at the outermost side, then the film to be cut is placed on the workbench 4, the two ends of the film to be cut cover the fixed slot 46, then the pressing rod 2 is placed in the fixed slot 46, then the film to be cut is pulled tight and flat by hand so that the film to be cut is parallel to the upper surface of the workbench 4, at this time, the bottom surface of the two ends is in contact with the top surface of the convex plate 41, and the bottom surface of the middle part is away from the upper surface of the workbench 4, then the pressing rod 2 is fixed with the workbench 4, then the longitudinal cutting device 1 is pulled to move to the other end of the workbench 4, the longitudinal cutter cuts the film (the part higher than the tip of the longitudinal cutter, almost all the part between the two fixed slots 46) into a long strip, then the pressing rod 2 is unfixed with the workbench 4, then the pressing plate 5 is pressed on the upper surface of the long strip film, and the upper transverse channel 51 is aligned with the lower transverse channel 45, then the pressing plate 5 is fixed with the workbench 4, at this time, the pressing plate 5 presses the long strip film on the upper surface of the workbench 4, then the transverse cutting device 3 is pulled, the transverse cutter cuts each long strip film into several sections to obtain a test sample, then the pressing plate 5 is removed, and the test sample can be collected. Because the long strip film on both sides of the transverse channel is pressed tight, the side of the long strip film facing the transverse cutter is not easy to roll up upward or downward, so the second cutter is easy to cut into the long strip film, and the edge of the long strip film is relatively smooth after being cut, and it will not be scrapped.
