Description

Technical Field

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

[0002] Metal thin films are ultra-thin layers made of metal or metal alloys, typically ranging in thickness from a few nanometers to several microns. During the manufacturing process, metal thin films can be subject to a range of issues, including wear and tear and material quality. Therefore, sampling is necessary to ensure product quality. Sampling is used to estimate and infer overall sample characteristics based on analysis and research results from individual sample units.

[0003] According to Chinese patent document CN208239107U, a thin film sampling device is disclosed, comprising a cutting plate and a knife holder. A film clamping device is provided around the cutting plate. The knife holder is mounted on the cutting plate, and a guide rail is provided on the knife holder. A plurality of retaining members are mounted on the guide rail, and the retaining members can slide along the guide rail. A first cutter is mounted on the retaining member, and the first cutter is arranged perpendicular to the guide rail. A second cutter is also mounted on the knife holder, and the second cutter is mounted on both sides of the first cutter and perpendicular to the first cutter. The above patent document has a film clamping device around the cutting plate to facilitate the fixation of the film and ensure that the film is fully spread on the cutting plate. The second cutter on the knife holder can be adjusted in position, suitable for cutting strips of different specifications. However, the above document has the following defects during implementation:

[0004] In the above-mentioned literature, the film is cut into strips by directly contacting the cutter with the work plate. After the cutter contacts or hits the work plate multiple times, the cutting edge of the cutter will become blunt and the work plate will become uneven, resulting in uneven edges of the sample and the presence of microscopic gaps, which greatly reduces the qualified rate of the cut samples. In addition, the above-mentioned literature adopts manual flattening on the work plate, which will result in incomplete flattening of the film and cause cutting errors. Utility Model Content

[0024] In order to make the technical means, creative features, objectives and effects achieved by the present invention easier to understand, the present invention is further described below in conjunction with specific implementation methods.

[0025] like Figure 1 As shown, a metal film sampling device comprises a bottom tray 1, the front and rear ends of the bottom tray 1 are symmetrically fixedly connected with a fixing plate 2, the upper ends of the four fixing plates 2 are fixedly connected with a support rod 3, the outer surfaces of the four support rods 3 are slidably connected to a cover frame 5, the four corners of the cover frame 5 are provided with sliding holes 10 communicating with the lower end, the inner surfaces of the four sliding holes 10 are fixedly connected with magnetic rings, and the four magnetic rings are slidably connected to the outer surfaces of the support rods 3 on the same side, the inner surface of the cover frame 5 is fixedly connected with a sliding rod assembly 7, the middle part of the left end and the middle part of the right end of the cover frame 5 are fixedly connected with a tension frame 6, a plurality of cutters 9 are fixedly connected to the middle of the bottom wall of the inner surface of the bottom tray 1, the front side wall and the rear side wall of the inner surface of the bottom tray 1 are fixedly connected with a sliding bracket assembly 4, and the middle part of the upper end frame of the bottom tray 1 is fixedly connected with a rolling device 8.

[0026] The support rod 3 is made of iron metal;

[0027] The magnetic ring can slide relative to the support rod 3, and the magnetic ring and the support rod 3 can provide a force to fix the sliding rod assembly 7 and ensure that the sliding rod assembly 7 is in a stable state;

[0028] During the implementation of this solution, the metal film is first placed on the rolling device 8, and then the sliding rod assembly 7 is moved downward to spread the metal film. The rolling device 8 is then rotated to make the metal film contact and cut with the cutter 9 to sample the precise metal film.

[0029] Specifically, in order to achieve the purpose of spreading the metal film by the sliding rod assembly 7, as shown in FIG. Figure 2As shown, in this solution, the sliding rod assembly 7 includes two sliding rails 71, and the ends of the two sliding rails 71 that are away from each other are fixedly connected to the inner surface of the cover frame 5 on the same side, and the ends of the two sliding rails 71 that are close to each other are slidably connected to two sliders 72, and the ends of the four sliders 72 close to the middle of the inner frame of the cover frame 5 are magnetically connected to magnetic blocks 75, and magnetic bars 74 are rotatably connected between the two magnetic blocks 75 on the left and the two magnetic blocks 75 on the right, and springs 73 are fixedly connected between the opposite surfaces of the two magnetic blocks 75 at the front and the opposite surfaces of the two magnetic blocks 75 at the back.

[0030] Since the spring 73 is fixed on the magnetic block 75, the two magnetic bars 74 are initially squeezed together by the elastic force. After the sliding bar assembly 7 moves downward and contacts the rolling device 8, it is subjected to an upward supporting force. The two magnetic bars 74 roll away from each other along the surface of the rolling device 8, flattening the metal film on the surface of the rolling device 8. When the two magnetic bars 74 are both stuck in the rolling device 8, the magnetic force between the slider 2 72 and the magnetic block 75 disappears and separates, allowing the magnetic block 75 and the magnetic bar 74 to be fixed on the rolling device 8.

[0031] Specifically, in order to achieve the purpose of separating the slider 2 72 from the magnetic block 75, as shown in Figure 4, the sliding bracket assembly 4 includes two slide rails 1 45, the ends of the two slide rails 1 45 away from each other are fixedly connected to the inner surface of the bottom tray 1 on the same side, and the ends of the two slide rails 1 45 close to each other are slidably connected to two slide blocks 1 44, and the ends of the four slide blocks 1 44 close to the middle of the inner frame of the bottom tray 1 are fixedly connected to the arc supporting rod 43, and the upper ends of the four arc supporting rods 43 are fixedly connected to the arc tray 41, and the middle parts of the four arc supporting rods 43 are rotatably connected to the rotating plate 46, and the ends of the two front rotating plates 46 and the two rear rotating plates 46 away from the arc supporting rod 43 are rotatably connected to the rotating shaft 47 together, and the ends of the front rotating shaft 47 and the rear rotating shaft 47 close to each other are rotatably connected to the rocking rod 42;

[0032] By rotating the rocker 42 to adjust the length of the rotating plate 46 to extend and retract, and thus to adjust the horizontal position of the arc support rods 43, the arc tray 41 is moved to the appropriate position, and the metal film is placed on the surface of the rolling device 8. When the magnetic rod 74 is vertically translated and contacts the surface of the rolling device 8, the magnetic rod 74 rolls outward along the surface of the rolling device 8 to spread the metal film flat. When the magnetic rod 74 is vertically translated to the height of the arc tray 41, the magnetic rod 74 receives an upward support force from the arc tray 41, the magnetic block 75 separates from the slider 2 72, and the magnetic rod 74 is engaged with the rolling device 8. Then, the rocker 42 is rotated to adjust the arc support rods 43 to move away from each other.

[0033] Specifically, in order to achieve the purpose of fixing the metal film on the rolling device 8, as shown in FIG. Figure 4 As shown, the rolling device 8 includes two fixed supports 84, the lower ends of the two fixed supports 84 are fixedly connected to the front end and the rear end of the bottom tray 1 respectively, and the upper ends of the two fixed supports 84 are jointly rotatably connected to a mounting shaft, the front end of the mounting shaft is fixedly connected to a rocker 83, and the middle part of the outer surface of the rocker 83 is fixedly connected to a rolling cylinder 81, and two symmetrically distributed concave cylindrical grooves 82 are provided on the upper left part and the upper right part of the outer surface of the rolling cylinder 81, and a plurality of vertical concave circular grooves 85 are provided in a vertical linear array on the outer surface of the rolling cylinder 81.

[0034] The radii of the two magnetic bars 74, the radii of the two concave cylindrical grooves 82, and the inner diameters of the four arc trays 41 are all the same;

[0035] The arc tray 41 moves to the place where the two circles of the concave cylindrical groove 82 overlap;

[0036] When the slider 2 72 is separated from the magnetic block 75, the magnetic bar 74 is stuck in the groove of the concave cylindrical groove 82. The metal film is clamped and fixed by the magnetic bar 74.

[0037] Specifically, in order to achieve the purpose of metal film sampling, such as Figure 4 and Figure 5 As shown, the number of the plurality of vertical concave circular grooves 85 and the number of the plurality of cutters 9 are the same and cooperate with each other. The rocker 83 is rotated to adjust the rolling of the rolling cylinder 81. The vertical concave circular grooves 85 are not in direct contact with the cutter 9. The cutter 9 directly cuts the metal film to complete the sampling.

[0038] The working principle of the present invention is as follows: first, the rocking rod 42 is rotated to translate the arc supporting rod 43, and it is moved to the position where the arc of the arc tray 41 overlaps with the circle of the concave cylindrical groove 82, and the metal film is placed on the surface of the rolling cylinder 81. The tension frame 6 is pulled to adjust the height of the magnetic rod 74. After contacting the surface of the rolling cylinder 81, the metal film is rolled and flattened so that it is stuck in the concave cylindrical groove 82. The rocking rod 42 is rotated to move the two adjacent arc supporting rods 43 away, and the rocking rod 83 is rotated to adjust the rolling cylinder 81 to make the cutter 9 cut the metal film to complete the sampling. Then the tension frame 6 is pulled upwards. When the slider 2 72 is parallel to the magnetic block 75, the magnetic force again absorbs the magnetic block 75, thereby driving the magnetic rod 74 to return to the sliding rod assembly 7 until it moves to the top of the support rod 3, and the sampling product of the metal film can be removed.

[0039] The above shows and describes the basic principles, main features and advantages of the present invention. Those skilled in the art should understand that the present invention is not limited to the above embodiments. The above embodiments and descriptions are merely illustrative of the principles of the present invention.
