[0034] The working principle of this utility model is as follows:

[0035] like Figures 1 to 6 As shown, before use, the partition 13 is inserted into the insertion hole formed by the first opening slot 110 and the second opening slot 113, and the two guide plates 12 are respectively attached to the outer walls of the left and right sides of the partition 13. The upper end surface of the partition 13 is flush with the upper end surface of the first box cover 111 and the second box cover 112. The upper end surface of the glass plate 51 is flush with the upper end surface of the fixing plate 11 to avoid the support block 41 being interfered with by movement.

[0036] According to the testing requirements, a glass plate with a corresponding light transmittance (e.g., 91.5% light transmittance) is used as a carrier (hereinafter referred to as the carrier). The carrier is first disinfected with alcohol and wiped clean with a lint-free cloth. Then, the carrier is placed horizontally on the support plate 116. A varnish sample is dripped onto the carrier, avoiding the baffle 31. The carrier is then pushed into the feed hole 22. Simultaneously, the lower end of the baffle 31 adheres to the upper end of the carrier. As the carrier is pushed further in, the lower end of the smear rod 3 adheres to the carrier, and a smoothing operation is performed on the varnish sample. The varnish sample then spreads evenly on the carrier until... The carrier enters the hot drying chamber completely through the feed inlet 22, and the carrier moves to the upper surface of the support block 41. That is, the carrier leaves the feed inlet 22 and is supported and placed by the support block 41. Since there is a guide block 12 extending out inside the chamber, after the carrier enters the hot drying chamber, an auxiliary tool (not shown) needs to be inserted into the feed inlet 22 to push the carrier further in a certain distance. It is advisable that the auxiliary tool has a distance scale line (not shown) so as to push the carrier to the position between the two guide blocks 12, so as to effectively avoid the situation of movement interference between the carrier and the guide block 12 when it is pushed to move in the subsequent process.

[0037] Then, take the cover 32, insert the limiting boss 321 into the positioning slot 115, so that the cover 32 covers the outside of the feed hole 22, to achieve the purpose of closing the feed hole 22; combined with the thickness of the varnish sample film and its related characteristics, the preset irradiation time is started, at this time, the heat lamp 2 is turned on to start heating, and the varnish film is dried by sunlight (normal condition is in the range of 20-40 minutes), then the heat lamp 2 is turned off.

[0038] Then, start the exhaust fan 21, pull the pull block 24 out of the cover plate 23, open the air supplement port 117, and at the same time of air pressure balance, the cold air from the outside can also enter, mix the temperature of the hot air, speed up the air cooling, and also cool the carrier, if necessary, the cover 32 can also be opened at this time to improve the air flow; after cooling for 6-8 minutes, pull the pull plate 114 to pull out the partition plate 13 from the box, cover the cover plate 23, and at this time the exhaust fan 21 is not closed, the cold air will also enter from the observation hole 118 and the insertion position of the partition plate 13 and flow to the hot drying grid, the hot air will not flow to the direction of the observation grid, that is, at this time the hot air will not move and adhere to the second box cover 112 to form water mist, which helps to clearly observe the sample transmittance.

[0039] Subsequently, the driving motor 4 is started, the connecting rod 40 is driven to push the supporting block 41 horizontally to the observation grid, and finally moves to the position of the groove 50, with the black paint layer 501 as the background color for observation, and the second box cover 112 is made of transparent PVC material, at this time, the staff can start visual detection of the transmittance of the varnish sample from multiple angles outside the observation grid, and also can reach in the observation grid 118 to flip or translate the carrier; under the premise that the carrier is not hot, the carrier can be held at this time, and the driving motor 4 is started to move the supporting block 41 back, so that the transmittance of the varnish sample can be completely observed without obstruction in the background of the black paint layer, compared with the transmittance of the carrier, the clear and impurity-free is qualified.

[0040] When the ambient light is relatively dark, the illuminating lamp 5 is turned on to supplement the brightness required for visual detection, which effectively ensures the accuracy and efficiency of the detection.

[0041] In addition, when two or more varnish samples need to be detected, one varnish sample is dropped on the carrier corresponding to the position between the two adjacent baffles 31, and then the above-mentioned related steps are operated, here, it needs to be explained that since the film of the sample will diffuse after being heated, the thickness of the baffle 31 needs to be greater than the displacement amount of the film layer, but combined with the characteristics of the thin film layer, the thickness size is set to prevent the sample from mixing; if a small part of the varnish sample has a large displacement after spreading, under the premise of reasonably setting the number of baffles 31, in order to avoid mixing between the samples, such varnish samples are preferably detected separately.

[0042] The storage cabinet 10 is provided for placing the varnish samples. In order to prevent the samples from falling out, a door plate (not shown) capable of being opened and closed is arranged at the position of the storage cabinet 10. The vehicle body 1 is convenient for moving between the warehouse and the detection room, so as to facilitate the movement of detection. Meanwhile, the power supply should be ensured to provide heating, accelerated cooling and lighting.
