[0005] (2) low solidification energy efficiency: need to maintain 1.5 hours above heat curing process in 70 DEG C constant temperature environment, rely on high energy consumption constant temperature equipment and the production efficiency is limited;

[0006] (3) interface bonding defect: solidified finished product lacks independent adhesion characteristic, must realize the combination with test surface by means of external adhesive, increases the interface failure risk;

[0010] (2) rheological control is insufficient: when operating on non-horizontal surface, material produces sagging, dripping phenomenon under the action of gravity, leads to the abnormal structure of non-uniform " stalactite " after solidification;

[0011] (3) weak process controllability: lack accurate thickness control mechanism, coating thickness deviation exceeds ± 30%, seriously influence the standardization of stress measurement and data comparability;

[0012] (4) limited in field application: large size component or fixed device need to rely on fixed heating equipment, cannot realize the instant coating-solidification integrated operation of outdoor scene.

[0013] The prior art system has technical faults in complex spatial surface treatment: it cannot guarantee uniform coating quality of multi-plane and special-shaped surfaces, and it is difficult to realize low energy consumption and high efficiency of on-site curing treatment. Especially in response to special working conditions such as inclined surface (30°-90°) and inverted surface, there are systematic defects such as uneven coating thickness, structural distortion and insufficient adhesion, which seriously restrict the popularization and application of stress luminescence measurement technology in the field of engineering monitoring.

[0034] like Figure 1 As shown, a multi-planar rapid coating and curing device for stress luminescent materials includes a detachable curing structure 1, which consists of two L-shaped frames and a top plate 12. The two L-shaped frames 11 and the top plate 12 are detachably connected to form a rectangular space by snap fasteners 5. The snap fasteners 5 are high-strength plastic snap fasteners, and the connection method is a keyboard switch structure to achieve rapid assembly and disassembly.

[0035] A high-temperature resistant flexible silicone sealing ring is embedded at the bottom edge of the L-shaped frame that contacts the surface to be coated. The sealing ring forms an airtight contact with the surface to be coated, preventing material leakage. Furthermore, both the L-shaped frame 11 and the top plate 12 are made of polytetrafluoroethylene (PTFE), a material with extremely weak adhesion to PDMS, which significantly reduces the difficulty of demolding and the risk of film damage.

[0036] Heating elements are provided on the outer surface of the top plate 12, which are in direct contact with the outer surface of the top plate 12 to achieve rapid heating and improve curing efficiency. Furthermore, the top plate 12 has replacement modules of different thicknesses. By replacing the top plate 12 with modules of different thicknesses, the coating thickness can be adjusted, enabling precise control of the cured layer thickness and meeting the needs of different stress measurement scenarios.

[0037] An injection structure 2 is connected to the surface of the L-shaped frame 11. The injection structure 2 includes a syringe 21 and a needle tube 22. The syringe 21 and the needle tube 22 cooperate to ensure controllable injection flow. An injection hole 3 is provided through the surface of the L-shaped frame 11. A single-valve check valve 4 is provided inside the injection hole 3. One end of the needle tube 22 is connected to the injection hole 3, and the other end is connected to the output end of the needle tube 22. The single-valve check valve 4 is made of rigid silicone, allowing material to flow in unidirectionally without flowing out. The valve automatically closes after the syringe 21 is withdrawn to prevent material leakage.

[0038] The device is also equipped with a demolding auxiliary structure, which includes a blade that scrapes into the top plate 12 at a 15° angle to achieve material separation.

[0039] Working principle:

[0040] Equipment preparation: Select an L-shaped frame suitable for the coating area and a top plate 12 of corresponding thickness, assemble them into a complete frame using plastic clips 5, and confirm that the sealing ring is installed in place;

[0041] Surface fixation: Place the assembled device on the target surface to be coated, ensuring that the sealing ring is in full contact with the surface to form an effective seal;

[0042] Preheating: Activate the heating element 12 on the top plate to preheat the device to 45-50℃, creating suitable conditions for subsequent material injection and curing;

[0043] Material preparation: Shake the stress-luminescent material thoroughly to ensure uniform distribution of components, and then introduce the material into syringe 21;

[0044] Injection operation: Insert the syringe 21 needle 22 into the injection hole on the side of the device, and slowly and evenly inject the material until the inner cavity of the frame is filled;

[0045] Pull-out sealing: After injection is completed, pull out syringe 21 vertically. At this time, the single-valve check valve 4 will automatically close to prevent material backflow.

[0046] Heat curing: Adjust the temperature of the heating element to 65-70℃ and maintain it for 30-45 minutes to ensure the material is completely cured;

[0047] Demolding: After curing, first remove the plastic clips 5, carefully separate the two L-shaped frames, and then use a blade to slowly scrape into the surface of the top plate 12 at a 15° angle to separate the material from the top plate 12, thereby ensuring that the strong adhesion between the cured layer and the surface to be tested is not affected.

[0048] Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of this utility model and not to limit it. Although the utility model has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can still be made to the technical solution of this utility model, and these modifications or equivalent substitutions cannot cause the modified technical solution to deviate from the spirit and scope of the technical solution of this utility model.
