Technical Field
[0001] This utility model relates to the fields of materials science and engineering technology, and in particular to a composite plate anti-corrosion salt spray testing device. Background Technology
[0002] Composite panels are widely used in aerospace, shipbuilding, and construction, and their corrosion resistance is crucial. Salt spray testing is a common method for evaluating the corrosion resistance of materials. However, traditional salt spray testing devices suffer from problems such as uneven salt spray distribution, insufficient temperature and humidity control accuracy, and low automation, making it difficult to meet the precise testing needs of composite panels in complex corrosive environments. With the improvement of industrial corrosion protection standards, there is an urgent need for a salt spray testing device that can simulate real corrosion scenarios, achieve precise parameter control, and be highly efficient and stable, so as to accurately evaluate the corrosion resistance of composite panels and provide a reliable basis for their application in harsh environments.
[0003] In existing technologies, composite plates need to be pre-cleaned before salt spray testing. However, this is usually done manually. Manual cleaning is inefficient, uneven pressure can leave scratches, and dust and impurities may cause deviations in salt spray test results. Furthermore, when performing detection and positioning after pre-cleaning, traditional devices rely on manual placement of the composite plate, which can easily lead to tilting and uneven test areas, resulting in deviations in test data.
[0004] To address this, a salt spray testing device for composite board corrosion resistance is proposed. Utility Model Content

[0015] Compared with the prior art, the beneficial effects of this utility model are:
[0016] 1. This application, by setting up a pre-cleaning mechanism, can automatically adjust the thickness of the laminated board by driving the cleaning roller with a servo motor. It realizes an automated pre-cleaning process of front-end cleaning and back-end drying through the cooperation of the liquid storage tank and the atomizing nozzle, thereby eliminating the need for manual operation, improving cleaning efficiency, and the uniform pressure of the cleaning roller can avoid scratches. Through the segmented treatment of atomized spraying and drying, the dust and impurities residue is reduced, which solves the problems of low efficiency, uneven pressure and impurity residue caused by manual wiping and deviation of test results, and ensures the accuracy of salt spray test.

[0025] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0026] Please see Figure 1-6 The present invention provides the following technical solution:
[0027] A composite panel anti-corrosion salt spray test device includes a salt spray chamber 1, a pre-cleaning mechanism 2 movably connected to the left side of the salt spray chamber 1, a positioning mechanism 3 movably connected to the bottom of the inner side of the salt spray chamber 1, a salt spray spray test device 4 movably connected to the right side of the inner side of the salt spray chamber 1, a movable door 5 rotatably connected to the front side of the salt spray chamber 1, and a positioning magnetic suction 6 fixedly connected to the inner side of the movable door 5.
[0028] The pre-cleaning mechanism 2 includes a cleaning box 21 fixedly connected to the left side of the salt spray chamber 1. A liquid storage tank 22 is fixedly connected to the top of the cleaning box 21. A liquid pump 23 is movably connected to the front of the liquid storage tank 22. An infusion tube 24 is movably connected to the front of the liquid pump 23. An atomizing nozzle 25 is fixedly connected to the outside of the infusion tube 24. The atomizing nozzle 25 is located at the top and bottom of the inner side of the cleaning box 21. A cleaning component 26 is movably connected to the inner side of the cleaning box 21.
[0029] In this embodiment: Before conducting the anti-corrosion salt spray test on the composite board, the surface of the composite board needs to be wiped clean to prevent dust or other impurities on the surface from affecting the salt spray test results. One end of the composite board to be tested is placed inside the cleaning box 21. The cleaning component 26 drives multiple sets of cleaning rollers 26b to adapt to the thickness of the composite board and conveys the composite board to the inside of the salt spray chamber 1. During this process, the liquid storage tanks 22 at the top and bottom of the cleaning box 21 draw internal cleaning liquid through the external liquid pump 23, which is then transmitted to the atomizing nozzle 25 through the liquid delivery pipe 24 and sprayed onto the surface of the front cleaning roller 26b, so that the front cleaning roller 26b is in a wiping and cleaning state, while the rear cleaning roller 26b remains dry. When the cleaning rollers 26b are conveyed in conjunction, the composite board is first wiped clean and then wiped dry, thereby achieving automatic pre-cleaning.
[0030] Specifically, such as Figure 1 , Figure 2 , Figure 5 As shown, the positioning mechanism 3 includes a feed inlet 31 located inside the salt spray chamber 1. The feed inlet 31 is located on the right side of the cleaning box 21. A guide inclined seat 32 is fixedly connected to the left side inside the salt spray chamber 1. A positioning plate 33 is rotatably connected to the top of the guide inclined seat 32.
[0031] Specifically, such as Figure 1 , Figure 2 , Figure 5 As shown, limit plates 34 are fixedly connected to both sides of the top of the guide inclined seat 32, and baffle 35 is fixedly connected to the right side of the top of the positioning plate 33. Clamping plate 36 is slidably connected to the inner side of the baffle 35 and is located inside the limit plate 34.
[0032] Specifically, such as Figure 1 , Figure 2 , Figure 5 As shown, a connecting rod 37 is rotatably connected to the top of the clamping plate 36, a linkage block 38 is rotatably connected to the outside of the connecting rod 37, an electronic telescopic rod 39 is fixedly connected to the bottom of the linkage block 38, and the electronic telescopic rod 39 is fixedly connected to the bottom of the baffle 35.
[0033] In this embodiment: the composite plate enters the salt spray chamber 1 through the inlet and is blocked by the outer limiting plate 34 to prevent it from moving outward. Due to its own weight and the transmission inertia of the cleaning roller 26b, the composite plate slides down the inclined surface of the guide seat 32. When it slides to the baffle 35 at the bottom of the top positioning plate 33 of the guide seat 32, the composite plate is stopped. At this time, the electronic telescopic rod 39 at the top of the baffle 35 is activated to correct the composite plate. The electronic telescopic rod 39 extends, driving the outer linkage block 38 to extend. When the linkage block 38 extends, its outer connecting rod 37 will rotate according to the extension distance and pull the clamping plate 36, which is normally attached to the inner wall of the limiting plate 34, to move inward, so that it is separated from the inner wall of the limiting plate 34. The two sets of clamping plates 36 move inward at the same time, pushing the composite plate to the center position and fixing it to prevent it from tilting.
[0034] Specifically, such as Figure 3 , Figure 4 , Figure 6 As shown, the cleaning assembly 26 includes a motor bearing seat 26a slidably connected to the inside of the cleaning box 21, a cleaning roller 26b rotatably connected to the inside of the motor bearing seat 26a, and a linkage rod 26c fixedly connected to the outside of the motor bearing seat 26a. The linkage rod 26c is slidably connected to the front of the cleaning box 21.
[0035] Specifically, such as Figure 3 , Figure 4 , Figure 6 As shown, a pull rod 26d is rotatably connected to the outer side of the linkage rod 26c, and a rotating block 26e is rotatably connected to the outer side of the pull rod 26d. A servo motor 26f is fixedly connected to the front side of the cleaning box 21, and the rotating block 26e is fixedly connected to the output end of the servo motor 26f.
[0036] In this embodiment: by activating the servo motor 26f on the outside of the cleaning box 21, the rotating block 26e at its output end rotates accordingly. When the rotating block 26e rotates, the two sets of pull rods 26d connected to the outside rotate around the axis, pulling the linkage rod 26c connected to the other end. The linkage rod 26c is connected to the motor bearing seat 26a on the inside of the cleaning box 21. The inside of the motor bearing seat 26a is equipped with multiple sets of cleaning rollers 26b with soft cleaning materials similar to wiping cotton on the outside. The rotation of the rotating block 26e drives the multiple sets of cleaning rollers 26b supported by the upper and lower motor bearing seats 26a on the inside of the cleaning box 21 to move inward at the same time, fitting the composite board part inside the cleaning box 21, and completing the adjustment to adapt to the thickness of the composite board to be tested.
[0037] Specifically, such as Figure 6 As shown, both sides of the positioning plate 33 are fixedly connected with linkage gears 7, and both sides of the inner side of the salt spray box 1 are fixedly connected with drive motors 8.
[0038] Specifically, such as Figure 6 As shown, the output end of the drive motor 8 is fixedly connected to the drive residual tooth 9, which is movably connected to the outside of the linkage gear 7.
[0039] In this embodiment: by starting the drive motor 8 on the inner wall of the salt spray chamber 1, the output end of the drive motor 8 drives the drive residual tooth 9 to rotate. Half of the drive residual tooth 9 has a toothed surface and the other half has a toothless surface. There is a drive residual tooth 9 on each of the linkage gears 7 on the outer side of both ends of the rotating shaft of the positioning plate 33. When the toothed surface of the drive residual tooth 9 contacts the linkage gear 7, the two are in a meshing state, realizing meshing transmission and driving the linkage gear 7 to rotate. When the toothless surface is in contact, the two are in a disconnected state, and the linkage gear 7 stops rotating. The connection states of the two sets of drive residual teeth 9 and linkage gear 7 are opposite. When one side is adjusted upward to the limit angle, the other side can mesh at the limit angle, causing it to descend and reset. In this way, a small-amplitude adjustment can be achieved in the salt spray chamber 1.
[0040] Working principle: Before conducting the salt spray test on the composite panel, the surface of the composite panel needs to be wiped clean to avoid dust or other impurities adhering to the surface, which could lead to deviations in the final salt spray test results. After placing one end of the composite panel to be tested inside the cleaning box 21, the servo motor 26f located on the outside of the cleaning box 21 is started, causing the rotating block 26e located at the output end of the servo motor 26f to rotate. During the rotation of the rotating block 26e, the two sets of pull rods 26d rotatably connected to the outside of the rotating block 26e will rotate axially and pull the linkage rod 26c rotatably connected to the other end. The linkage rod 26c is connected to the motor bearing seat 26a inside the cleaning box 21, and the inner side of the motor bearing seat 26a is equipped with multiple sets of externally flexible... The cleaning rollers 26b, made of a similar material to a scrubbing cotton, are used to achieve the following: The rotation of the rotating block 26e drives multiple sets of cleaning rollers 26b, supported by the upper and lower motor bearing seats 26a inside the cleaning box 21, to move inward simultaneously. They then conform to the portion of the composite board located inside the cleaning box 21, thus adapting to the thickness of the composite board to be tested. The motor and gear set inside the motor bearing seat 26a then drive the entire cleaning roller 26b, along with the composite board, into the salt spray chamber 1. During this process, the liquid storage tanks 22 located at the top and bottom of the cleaning box 21 draw out the cleaning liquid through the external pump 23. This liquid is then transported through the infusion pipe 24 and sprayed onto the surface of the front cleaning rollers 26b after reaching the atomizing nozzle 25. This causes the front cleaning rollers to... Cleaning roller 26b is in a wiping and cleaning state, while the rear cleaning roller 26b remains dry. When the composite board is transferred through cleaning roller 26b, it will be wiped and cleaned first, and then wiped and dried, thus achieving an automatic pre-cleaning effect. This eliminates the need for manual cleaning, which results in poor cleaning effect and long preparation time, and avoids dust and impurities affecting the overall test results. When the composite board is transferred to the tail end, it will enter the salt spray chamber 1 through the inlet and be blocked by the limit plate 34 on the outside. Due to its gravity and the transmission inertia of cleaning roller 26b, it will slide down the inclined angle of guide seat 32 and stop when it slides to the baffle 35 at the bottom end of the top positioning plate 33 of guide seat 32. The composite plate is corrected by activating the electronic telescopic rod 39 at the top of the baffle 35. As the electronic telescopic rod 39 extends, the linkage block 38 located outside the electronic telescopic rod 39 extends as well. During the extension of the linkage block 38, its outer connecting rod 37 rotates according to the extension distance, pulling the clamping plate 36, which is normally attached to the inner wall of the limiting plate 34 and rotatably connected to its other end, inward and disengaging from the inner wall of the limiting plate 34. The composite plate is pushed to the center position and fixed by the simultaneous inward movement of the two clamping plates 36, preventing it from tilting. After the positioning is completed and the clamping plates 36 disengage from the limiting plate 34, the drive motor 8 on the inner wall of the salt spray chamber 1 can be activated, causing the output end of the drive motor 8 to drive the residual tooth 9 to rotate. The residual tooth 9 has one toothed surface and one toothless surface.Furthermore, a linkage gear 7 is located on each of the outer sides of the rotating shaft at both ends of the positioning plate 33. When the tooth surface of the driving residual tooth 9 contacts the linkage gear 7, it is in a meshing state, engaging and driving the gear to rotate. When there is no tooth surface contact, it is in a disconnected state and stops rotating. The connection states of the driving residual teeth 9 and the linkage gear 7 are opposite. When one side is adjusted upward to the limit angle, the other side can mesh at the limit angle to lower and reset it. This allows for small-scale adjustment within the salt spray chamber 1. After the pre-cleaning, positioning, and adjustment are completed, the system is tested using the salt spray test equipment 4 and observed through the movable door 5. Any problems in the overall process are corrected in a timely manner. In summary, this achieves the salt spray test for corrosion resistance of the composite board.
[0041] The above are merely preferred embodiments of the present utility model and are not intended to limit the present utility model. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
