Furthermore, the terms "first" and "second" are used only for descriptive purposes and are not intended to have a special meaning.
The technical scheme of the invention is further explained by the specific implementation mode in combination with the attached drawings.
As shown in fig. 1, the present embodiment discloses a coating thickness detection apparatus, which includes a setting module 1, a detection module 3, an identification module 2, and an infrared thermal imaging projection module 4. The coating thickness detection device is mainly used for detecting the thickness of a coating in real time.
In particular, the setting module 1 is used to set the standard thickness of the coating, the detection zone 7 and the extension length. The detection module 3 is used to detect the coating thickness at selected detection points within the detection zone 7. The identification module 2 is in communication connection with the detection module 3, the identification module 2 can compare the coating thickness of the detection points with the standard thickness, so that the area where the detection points with the coating thickness smaller than the standard thickness are located is divided into unqualified areas 9, and the average thickness of the detection points in the unqualified areas 9 is calculated. The infrared thermal imaging projection module 4 is in communication connection with the identification module 2. When the infrared thermal imaging projection module 4 is over against the coating, the thickness of the coating can be rapidly detected, the boundary range of the unqualified area 9 of the coating and the average thickness corresponding to the coating of the unqualified area 9 are displayed on the surface of the coating, the real-time monitoring and visual detection of the thickness of the coating are realized, the detection workload is reduced, and the detection efficiency is improved.
As shown in fig. 2, the coating thickness detection method adopted by the coating thickness detection apparatus of the present embodiment is as follows:
s1: the standard thickness of the coating, the detection region 7 and the extension length are set in the setting module 1.
S2: the infrared thermal imaging projection module 4 faces the detection area 7, and a plurality of detection points are selected in the detection area 7.
S3: the coating thickness at each inspection point is detected by the detection module 3 and transmitted to the identification module 2, which compares the coating thickness with a standard thickness.
If the thickness of the coating is smaller than the standard thickness, the corresponding detection point is an unreached punctuation point; and dividing the expansion area by taking the unreached punctuations as the center of a circle and the expansion length as the radius.
S4: the steps S2 to S3 are repeated in the extension area until all the unreachable dots in the detection area 7 are detected.
S5: dividing the area where the unqualified punctuation is located into unqualified areas 9, calculating the average thickness of the unqualified punctuation in the unqualified areas 9 by the identification module 2, and transmitting the boundary value of the unqualified areas 9 and the corresponding average thickness to the infrared thermal imaging projection module 4 so as to project the boundary of the unqualified areas 9 and the corresponding average thickness on the surface of the coating.
According to the coating thickness detection method, the boundary of the unqualified area 9 and the corresponding average thickness of the unqualified area are projected to the surface of the coating through the infrared thermal imaging projection module 4, so that the visualization of the coating thickness is realized, and detection personnel can rapidly and intuitively determine the unqualified area 9 of the coating and the corresponding average thickness of the coating. The coating thickness detection method can be used for monitoring the coating thickness in real time, so that the phenomenon that a wet film card is frequently used for measurement in the construction process or an electromagnetic film thickness meter is frequently used for contact measurement after construction is avoided, the inspection workload is reduced, and the inspection efficiency is improved.
The standard thickness of this example is a range value. For example, the standard thickness may be 10mm to 15 mm. And when the coating thickness corresponding to the detection point does not fall into the standard thickness, the detection point is determined as an unreached punctuation point. At the moment, the detection point is taken as a circle, the extension length is taken as a radius to divide an extension area, and the detection point is reselected in the extension area to carry out coating thickness detection. And so on until the boundaries of all the defective areas 9 within the detection area 7 are obtained.
It should be noted that, when the corresponding extension area is divided for each substandard point, if the ranges of multiple extension areas overlap, only a single detection needs to be performed on the overlapping area, so as to avoid repeated detection, and improve the detection efficiency. In addition, when the extension area is divided, the boundary of the extension area cannot exceed the boundary of the detection area 7.
The extended length of this embodiment is 1cm to 2 cm. For example, the extended length is 1cm, 1.2cm, 1.5cm, 2cm, or the like. The specific value of the extension length can be set according to the actual detection situation.
In the present embodiment, the same detection region 7 includes a qualified region and a rejected region 9, and when the boundary value of the rejected region 9 is obtained, the other regions in the detection region 7 are qualified regions. The infrared thermal imaging projection module 4 of the coating thickness detection apparatus may also display the average thickness of the coating in the acceptable area within the acceptable area.
Since the qualified area in the detection area 7 is relatively large, in order to improve the accuracy of the average thickness of the coating in the qualified area, step S1 further includes: the detection area 7 is divided into a plurality of unit areas 8. As shown in fig. 3, one detection area 7 may be divided into four equal unit areas 8, and a certain number and distribution of detection points may be selected in each unit area 8 to increase the accuracy of projection. Of course, two, three, or five or more unit regions 8 may be adaptively provided according to the specific area of the detection region 7.
Specifically, step S5 further includes: and dividing the part of each unit area 8, from which the unqualified area 9 is removed, into qualified areas, calculating the average thickness of detection points in each qualified area by the identification module 2, and transmitting the boundary value and the corresponding average thickness of each qualified area to the infrared thermal imaging projection module 4 so as to project the boundary and the corresponding average thickness of each qualified area on the surface of the coating.
Continuing with FIG. 2, step S5 is followed by step S6: defective areas 9 are marked on the coating and the spraying is continued in the defective areas 9. Step S7 is also included after step S6: steps S2 to S6 are repeated until the coating thickness at all the inspection points in the inspection area 7 is equal to the standard thickness. The defective region 9 is re-sprayed and inspected through steps S6 and S7 until the coating thickness in the inspection region 7 reaches the standard thickness.
The method for detecting the thickness of the coating can be used for detecting the thickness of a wet film in the construction process or the thickness of a dry film after construction.
In the construction process, the coating thickness detection device is used for construction assistance, the standard thickness, the detection area 7 and the extension length of the wet film can be set in the coating thickness detection device, and the wet film detection is carried out according to the coating thickness detection method. And after multiple coating thickness tests, the coating thickness of the wet film meets the standard thickness. And after the construction is finished, the coating thickness detection device is used for verifying the coating quality, and the coating thickness detection of the dry film is finished by a coating thickness detection method. The coating is prevented from being too thin to meet the use requirement, or the coating is too thick, coating is wasted, and the cost is increased.
The detection module 3 of this embodiment includes a laser unit and an infrared detector, the laser unit is used for emitting laser to the coating, and the infrared detector can obtain the thickness of the coating according to the temperature change of the coating irradiated by the laser. The thickness of the coating is measured by the detection module 3 through a photothermal method, the coating does not need to be contacted, and the surface quality of the coating is prevented from being damaged. The coating thickness detection device of the embodiment replaces the functions of a wet film card and an electromagnetic film thickness meter, and reduces the labor intensity of detection personnel.
As shown in fig. 1, the coating thickness detection apparatus further includes a housing 5, and the setting module 1, the detection module 3, the identification module 2, and the infrared thermal imaging projection module 4 are all installed in the housing 5. The housing 5 may be a protective casing of the coating thickness detection apparatus. An independent power supply is mounted in the housing 5. The independent power supply can be a battery to ensure that the coating thickness detection device is a portable detection device, so that the operation limitation of power supply is reduced, and the use scene of the coating thickness detection device is favorably expanded. Further, the independent power supply is a lithium battery so as to prolong the service time of the coating thickness detection device.
As shown in fig. 1, a handle 6 or a mounting seat extends from the outer edge of the housing 5, so that the coating thickness detection device can be handheld, and the coating thickness detection device can be conveniently and quickly aligned to any detection area 7 by an inspector. Or the coating thickness detection device is placed on the working platform or the mechanical arm through the mounting seat, so that the intelligent detection of the coating thickness detection device is realized.
