[0020] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

[0021] Reference Figure 1-4 , a super-thin graphite paper uniform scraper, comprising a base plate 1, a spring clip 2 is installed on one side of the top of the base plate 1, a graphite paper 3 is placed on the top of the base plate 1 and fixed by the spring clip 2, ear plates 4 are installed on both sides of the rear end of the base plate 1 by screws, and a rodless cylinder 5 is installed between the two ear plates 4, the rodless cylinder 5 includes a slide seat 6 that slides on the outside of its cylinder barrel, a ball slider 7 is connected to the front side of the slide seat 6, a cantilever 8 is fixed to the top of the ball slider 7, and one end of the cantilever 8 is connected to a guide block 9, guide holes are opened on both sides of the top of the guide block 9, and a guide rod 10 is slid through the guide hole, the bottom ends of the two guide rods 10 are commonly connected to a lower connecting block 11, a knife edge ruler 12 is provided below the lower connecting block 11, a compression spring 13 is installed in the middle position between the lower connecting block 11 and the guide block 9, the tops of the two guide rods 10 are commonly connected to an upper connecting block 14, and an adjusting screw 15 is installed through a thread in the middle of the upper connecting block 14;

[0022] The technical solution adopted above is as shown in the attached figure. The spring clip 2 cooperates with the base plate 1 in the form of a dovetail clip. By placing the graphite paper 3 flat on the base plate 1 and clamping one end with the spring clip 2, it is prevented from sliding when applying glue. By applying special glue on the blade of the knife edge 12 in advance, and making the knife edge of the knife edge 12 fit with the surface of the graphite paper 3, the knife edge 12 is initially located at the leftmost side of the graphite paper 3, and then starting the rodless cylinder 5 to drive the ball slider 7 to slide to the right. The ball slider 7 drives the knife edge 12 to move to the right together through the cantilever 8, and the glue is evenly coated on the surface of the graphite paper 3. The lower connecting block 11, the guide rod 10, the guide block 9, and the upper The function of the connecting block 14 and the adjusting screw 15 is that by screwing the adjusting screw 15 downward, the bottom end of the adjusting screw 15 abuts against the upper surface of the guide block 9, and the position of the guide block 9 remains unchanged. As the adjusting screw 15 continues to be screwed downward, the upper connecting block 14 will be prompted to move upward relative to the guide block 9. The movement of the upper connecting block 14 will drive the lower connecting block 11 to move upward together through the guide rod 10 and squeeze the compression spring 13. At this time, the vertical height of the blade 12 can be adjusted to facilitate its blade to fit the surface of the graphite paper. Conversely, by screwing the adjusting screw 15 upward, the blade 12 will be adjusted to move downward due to the elastic reset effect of the compression spring 13.

[0023] A ball bearing rail 16 is installed on the top of the base plate 1, and the ball bearing slider 7 is slidably connected to the ball bearing rail 16;

[0024] The technical solution adopted above facilitates the stable planar movement of the ball slider 7 through the ball slide rail 16 .

[0025] The rear end of the lower connecting block 11 is connected to a connecting rod 17, and a positioning block 18 is provided on the side of the connecting rod 17. The positioning block 18 and the connecting rod 17 are connected by a butterfly screw 21. The bottom end of the positioning block 18 is fixedly connected to a tool holder 19. The two ends of the tool holder 19 are connected to a tool clamp 20. The tool clamp 20 is fixedly connected to the blade ruler 12 with screws;

[0026] The technical solution adopted above adopts a butterfly screw 21 to connect the lower connecting block 11 and the tool holder 19, so as to facilitate the overall disassembly of the tool holder 19 together with the blade ruler 12 for cleaning.

[0027] A spring limiting groove 22 is provided at the middle of the top of the lower connecting block 11 and the middle of the bottom of the guide block 9. The two ends of the compression spring 13 are respectively inserted into the spring limiting grooves 22 at the upper and lower positions;

[0028] The technical solution adopted above adopts the spring limiting groove 22 to conveniently limit the two ends of the compression spring 13 so that it is not easy to run out from between the lower connecting block 11 and the guide block 9, or other structures that limit the position of the compression spring 13 can be adopted.

[0029] One end of the cantilever 8 is connected to the guide block 9 by two hand-tightened screws 24. A pin 25 is installed in the middle of the rear end of the lower connecting block 11. A composite bushing is provided at the top of the connecting rod 17, and the connecting rod 17 is sleeved on the outside of the pin 25 through the composite bushing.

[0030] In the technical solution adopted above, the cantilever 8 and the guide block 9 are connected by a hand-tightened screw 24, which facilitates the overall installation and disassembly of the guide block 9. The connecting rod 17 and the lower connecting block 11 are connected by a composite bushing and a pin 25, which can enable the blade 12 to adjust the angle radially, and cooperate with the action of the compression spring 13 to ensure that the blade of the blade 12 is in full contact with the graphite paper 3, thereby ensuring uniform glue coating.

[0031] A groove 23 is formed on the other side of the top of the bottom plate 1, and the surface of the groove 23 is lower than the plane of the graphite paper 3.

[0032] In the technical solution adopted above, when the blade 12 moves from left to right to apply glue, excess glue will be scraped to the inside of the groove 23.

[0033] Working principle:

[0034] The specific operating steps of the device are as follows: ① The gap between the blade ruler 12 and the graphite paper 3 can be adjusted by rotating the adjusting screw 15. Since the top structure of the tool holder 19 and the guide block 9 are connected by a shaft and a sleeve, it can ensure that the blade ruler 12 and the graphite paper 3 are in full contact. The angle can be adjusted at any time along the surface of the graphite paper 3. This mechanism can adjust the blade ruler 12 to just contact the graphite paper 3.

[0035] ② Lift the adjusting screw 15 to lift the blade 12 as a whole, and remove the blade 12 from the butterfly screw 21. After removal, apply special glue on the blade of the blade 12.

[0036] ③ Place a 0.2mm rectangular graphite paper 3 vertically on the base plate 1 and clamp it with a spring clip 2 to prevent the graphite paper 3 from moving;

[0037] ④ Move the blade ruler 12 to the leftmost starting position through the rodless cylinder 5;

[0038] ⑤. Lift the adjusting screw 15 and reconnect the glued blade 12 to the connecting rod 17 through the butterfly screw 21. Gently lower the blade 12 so that the blade of the blade 12 is completely in contact with the graphite paper 3.

[0039] ⑥. Press the cylinder switch, and the cylinder will slowly move to the right at a certain speed. At this time, the glue on the blade 12 will be evenly coated on the graphite paper 3 according to a fixed thickness.

[0040] ⑦. Remove the graphite paper 3, place it horizontally on the bottom plate 1, clamp it with the spring clip 2, and repeat the above steps.

[0041] ⑧. After gluing is completed, the seed crystal is attached to the graphite paper 3 and the excess graphite paper 3 is cut according to the outer circle of the seed crystal.

[0042] The above is only a preferred specific implementation method of the present invention, but the protection scope of the present invention is not limited to this. Any technician familiar with the technical field within the technical scope disclosed by the present invention can make equivalent replacements or changes based on the technical solution and utility model concept of the present invention, which should be covered by the protection scope of the present invention.
