[0004] In the prior art including the above-mentioned patent, in the development of PC board, spraying nanometer coating on the surface of PC board can make PC board not only smoother, but also prevent liquid from sticking to the surface of PC board. However, during the manufacturing process of nanometer coating of PC board, the nanometer coating may not be uniformly coated on the outer wall of PC board, but the nanometer coating cannot be observed by naked eye, which makes the user unable to observe whether the coating is uniform or not or the place where the coating is unstable. UTILITY MODEL CONTENTS

[0005] The utility model aims at providing a kind of nanometer coating scratch resistance testing device of hardening PC board to solve the problems raised in the above background.

[0006] To achieve the above object, the utility model provides the following technical scheme: a kind of nanometer coating scratch resistance testing device of hardening PC board, including body, the top of the inner wall of the body is equipped with cylinder, the output end of the cylinder is equipped with connecting rod, one end of the connecting rod is connected with connecting plate, the bottom of the connecting plate is connected with bottom plate, the outer wall of the bottom plate is connected with mounting rod, the outer wall of the mounting rod is provided with linkage block, one end of the mounting rod is connected with scraper, the outer wall of the linkage block is equipped with sliding slot, the bottom of the outer wall of the connecting plate is equipped with linkage rod, one end of the linkage rod is connected with connecting rod mechanism, the outer wall of the connecting rod mechanism is equipped with pump housing.

[0007] Further, one end of the connecting rod mechanism is movably connected with plunger valve assembly, the bottom of the inner wall of the pump housing is provided with rubber one-way valve, the bottom of the outer wall of the pump housing is connected with water tank, the outer wall of the pump housing is connected with water pipe, one end of the water pipe is provided with spray head.

[0008] Further, the bottom of the body inner wall is provided with a placing table, and the outer wall of the placing table is provided with a plate.

[0009] Further, the three-dimensional view of the linkage block is in the shape of a cylinder, and the diameter of the outer wall of the linkage block is matched with the diameter of the sliding groove.

[0010] Further, one end of the connecting rod mechanism is connected with a linkage rod, and the other end of the connecting rod mechanism is movably connected with a plunger valve assembly.

[0011] Further, one end of the connecting rod is connected with the output end of the air cylinder, and the other end of the connecting rod is connected with the outer wall of the connecting plate.

[0012] Compared with the prior art, the nano coating scratch resistance testing device for the hardened PC plate has the following advantages:

[0013] Through the driving action of the air cylinder, the connecting rod mechanism and the plunger valve assembly are cooperatively worked, so that water is pumped into the water tank and sprayed onto the surface of the plate through the spray head. This design allows the tester to judge the uniformity of the nano coating by observing the distribution and behavior of the water flow on the surface of the plate without directly contacting the plate. If the coating is uniform and dense, the water droplets will drop from the surface of the plate. If the coating is uneven or has defects, the water droplets may be retained or form a water film on the surface of the plate. This method provides an intuitive, fast and non-destructive testing method, which is helpful for evaluating the quality of the nano coating.

[0014] The scraper driven by the air cylinder reciprocates on the surface of the plate to simulate the scratching situation that may be encountered in actual use, so as to test the scratch resistance of the nano coating. The movement of the scraper is controlled by the air cylinder, which can accurately control the intensity and frequency of the scratching to simulate different intensity of scratching. By observing the scratches, coating peeling or other damage on the surface of the plate after scratching, the wear resistance and protection effect of the nano coating can be evaluated. This testing method provides quantitative and qualitative evaluation for the scratch resistance of the coating, which is helpful for optimizing the coating material and process.

[0026] In this embodiment, plunger valve assembly 13 is movably connected to one end of connecting rod mechanism 11, rubber check valve 14 is arranged on the bottom of the inner wall of pump shell 12, water tank 15 is connected to the bottom of the outer wall of pump shell 12, water pipe 16 is connected to the outer wall of pump shell 12, and spray head 17 is arranged on one end of water pipe 16.

[0027] In this embodiment, placing table 18 is installed on the bottom of the inner wall of machine body 1, and board 19 is arranged on the outer wall of placing table 18.

[0028] In this embodiment, the three-dimensional view of the linkage block 7 is cylindrical, and the diameter of the outer wall of the linkage block 7 is adapted to the diameter of the slide groove 9. When the mounting rod 6 moves, the linkage block 7 installed on its outer wall slides along the inner wall of the slide groove 9.

[0029] In this embodiment, one end of the linkage mechanism 11 is connected to the linkage rod 10, and the other end of the linkage mechanism 11 is movably connected to the plunger valve assembly 13. When the linkage rod 10 moves, it will drive the linkage mechanism 11 to move. When the linkage mechanism 11 moves, it will drive the plunger valve assembly 13 and the rubber check valve 14 to cooperate with each other to pump water into the inner wall of the water tank 15.

[0030] In this embodiment, one end of the connecting rod 3 is connected to the output end of the cylinder 2, and the other end of the connecting rod 3 is connected to the outer wall of the connecting plate 4. After the cylinder 2 is started, its output end will drive the connecting rod 3 to move, and the connecting rod 3 will drive the connecting plate 4 to move when it moves.

[0031] Working principle: When in use, the user first places the board 19 on the outer wall of the placement platform 18, and then starts the cylinder 2. After the cylinder 2 is started, its output end will drive the connecting rod 3 to move. When the connecting rod 3 moves, it will drive the connecting plate 4 to move. When the connecting plate 4 moves, it will drive the base plate 5 to move. When the base plate 5 moves, it will drive the mounting rod 6 to slide.

When the scraper 8 scrapes, the nano-coating on the outer wall of the board 19 can be tested.

[0032] Secondly, when the connecting plate 4 moves, it will drive the linkage rod 10 to move. When the linkage rod 10 moves, it will drive the linkage mechanism 11 to move.

The water will be discharged through the water pipe 16 connected to the pump housing 12 and sprayed onto the outer wall of the plate 19 through the nozzle 17 connected to one end of the water pipe 16. If the nano-coating on the outer wall of the plate 19 is uniform and does not fall off after being scraped by the scraper 8, then the water will drip from the outer wall of the plate 19. If the nano-coating is not uniform, the water droplets will stay on the outer wall of the plate 19. The user can judge whether the nano-coating is uniform and tightly applied by the state of the water. At this point, the practical work is completed.

[0033] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description. Thus, it is intended that all variations falling within the meaning and scope of equivalents of the claims be included within this invention. No reference numerals in the claims should be construed as limiting the scope of the claims.
