Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of fluorescent detection spraying equipment, in particular to a developer spraying equipment for fluorescent penetration detection. BACKGROUND

[0002] Fluorescent penetrant is a detection method that after the surface of the detected part is coated with fluorescent agent, the surface fluorescent agent is cleaned, the crevice of the part penetrates the fluorescent agent, and then the developer is coated, which will directly show the crevice under ultraviolet irradiation. It is mainly used for checking non-porous materials such as metal, plastic, ceramic and glass. Generally, it includes cleaning the part or preparing the surface to be checked, applying fluorescent penetrant to the product, and allowing it to remain during the process of "wetting" the part surface, removing excess penetrant, applying developer to "print" the penetrant on the part surface, and checking the part under ultraviolet light to find signs of cracks or other surface discontinuities.

[0003] In the prior art, the publication number "CN114839198B" discloses an automatic fluorescent penetration detection line spraying and cleaning device and use method. The multi-layer spoke spraying plate will be positioned outside the corresponding spoke under the contact action of the turning assembly and each spoke. After the pipe frame turns one circle, each spoke outer circle on the hub will be accurately positioned with a spoke spraying plate. The inner and outer positioned spoke spraying plates can accurately spray each spoke, reduce the situation that the whole straight spray material is easily sprayed out from the spoke gap, reduce the waste of spray material, and can be applied to multiple links of fluorescent liquid spraying, fluorescent liquid cleaning, developer spraying and overall cleaning in fluorescent detection, reduce the construction cost of the detection line, improve the overall detection efficiency, and solve the problem that the existing developer spraying equipment is very inconvenient for production line detection of different specifications of hubs and has low detection efficiency.

[0004] However, the prior art still has great deficiencies, such as:

[0005] At present, in order to save fluorescent agent and developer, the traditional soaking type is replaced by spraying. For tubular or planar inclined surface parts, uniform spraying can be achieved. When spraying on square pipes and circular pipes, the clamping assembly in the spraying equipment is used to clamp and fix the pipes. Since the clamping assembly in the traditional spraying equipment can only fix the inner wall or the outer wall of the pipe, the position of the pipe that is blocked by the clamping assembly cannot be sprayed, which affects the detection of the pipe. In addition, dust from the outside will fall on the pipe during spraying. Although it can be removed by cleaning, dust from the outside will still fall on the pipe during position fixing. If these dusts are not cleaned before spraying, it will affect the developing effect of the developer and the detection of the pipe. SUMMARY

[0070] Working principle:

[0071] When spraying the inner wall of the pipeline, when the inner wall of the pipeline needs to be sprayed, the two ends of the pipeline are clamped between the clamping assemblies, and then the motor is started to drive the gear to rotate, the limit column 9 on the moving frame 7 is limited in the arc-shaped slot on the gear 12, and the pipeline is clamped and fixed by the four clamping blocks 8.

[0072] The installation plate 16 is horizontally moved by driving the push rod, and the stability of the installation plate 16 during movement is guaranteed by limiting the limiting plate 15, the position of the installation plate 16 is adjusted, and the position of the gear three 18 is adjusted, when the gear three 18 is engaged with the gear four 21 on the threaded rod one 19, the threaded rod one 19 is driven to rotate by the rotation of the gear three 18, when the gear three 18 is engaged with the gear four 21 on the threaded rod two 20, the threaded rod two 20 is driven to rotate by the rotation of the gear three 18, and the position of the gear three 18 is adjusted to facilitate spraying the developer on the inner and outer walls of the pipeline.

[0073] The installation cylinder 22 is driven to rotate by the rotation of the threaded rod one 19, and the installation cylinder 22 can move horizontally during rotation through the threaded installation between the installation cylinder 22 and the vertical plate 2, the installation cylinder 22 directly enters the inner wall of the pipeline through the through slot, the gas is filled into the exhaust tank 24 by starting the air pump one 25, the gas in the exhaust tank 24 enters the exhaust passage 26 through the connecting pipe, and the gas in the exhaust passage 26 finally blows into the inner wall of the pipeline through the outlet, the dust in the inner wall of the pipeline is cleaned by blowing in the gas, then the developer in the storage tank one 23 enters the liquid discharge passage 27 through the connecting pipe, the developer in the liquid discharge passage 27 is directly sprayed on the inner wall of the pipeline through the spray head one 28, the storage tank on the installation cylinder 22 rotates with the installation cylinder 22, so that the developer in the storage tank does not precipitate, and the rotation of the installation cylinder 22 can make the spraying effect of the spray head one 28 better, and the dust in the inner wall of the pipeline is cleaned before spraying, which improves the spraying effect of the developer;

[0074] When the outside wall of the pipe needs to be sprayed, the four clamping blocks 8 are inserted into the inner wall of the pipe, and then the moving frame 7 is moved outward by rotating the gear two 12 driven by the motor, and the pipe is fixed in position by the four clamping blocks 8;

[0075] The rotation of the threaded rod two 20 drives the tooth column 32 to rotate, which in turn drives the gear five 31 to rotate through the meshing of the tooth column 32 and the gear five 31. The rotation of the gear five 31 drives the rotating block 29 to rotate, which in turn drives the clamped pipe on the rotating block 29 to rotate. At the same time, the threaded rod two 20 drives the fixed frame 30 to move horizontally when it rotates. The storage tank two 33 on the fixed frame 30 drives the storage tank two 33 to input the developing agent in the storage tank two 33 into the liquid outlet pipe 35 through the pump body 34, and finally sprays the outside wall of the pipe through the nozzle two. The rotation of the clamped pipe improves the effect of developing agent spraying;

[0076] Starting the air pump two 36 fills the gas into the pipe one 37, part of the gas in the pipe one 37 enters the annular pipe 38, and through the gas outlet pipe 39 on the annular pipe 38, it directly blows to the outer wall of the pipe, so as to clean the dust on the outer wall of the pipe and ensure the cleanliness of the pipe when spraying the developing agent;

[0077] Part of the gas in the pipe one 37 enters the pipe two 40, and the gas in the pipe two 40 enters the push cylinder 44. When the pressure in the push cylinder 44 reaches a certain value, it will be directly discharged from the exhaust pipe of the push cylinder 44. The push block 46 in the push cylinder 44 will quickly rise through the elastic performance of the spring 45, and when it rises, it will drive the top rod 47 to extend into the rotating cylinder 41. The rotating cylinder 41 rotates through the rotating block 42 at the inner bottom of the storage tank two 33, and through the threaded connection of the top rod 47 and the rotating cylinder 41, it drives the rotating cylinder 41 to rotate. The rotating cylinder 41 drives the stirring blade 43 to rotate when it rotates, and the stirring blade 43 stirs the developing agent in the storage tank two to avoid the phenomenon of developing agent precipitation in the storage tank two.

[0078] Although embodiments of the present application have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made therein without departing from the principles and spirit of the application, the scope of which is defined by the appended claims and their equivalents.
