DETAILED DESCRIPTION

[0019] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0020] Example 1 An adjustable diffuser plate detection tooling, such as Figure 1-Figure 8 As shown, it includes a detection cabinet 10, a mounting frame 1, a lampshade 2 and an LED lamp 3; two mounting frames 1 are welded in the detection cabinet 10, and the two mounting frames 1 are symmetrically arranged; an exhaust pipe is arranged on the upper part of the detection cabinet 10; a lampshade 2 is fixedly connected between the two mounting frames 1; ten LED lamps 3 are installed in the lampshade 2; It also includes a mounting frame 2 4, a receiving platform 5, a cylinder 1 6, a rubber suction cup 7, an air pipe 1 8 and a light sensor 9; a mounting frame 2 4 is fixedly connected between two mounting frames 1, and the mounting frame 2 4 is located below the lampshade 2; two receiving platforms 5 are welded on the mounting frame 2 4 at equal intervals; a cylinder 1 6 is fixedly connected to each of the two mounting frames 1; a rubber suction cup 7 is fixedly connected to the telescopic ends of the two cylinders 1 6; five air pipes 1 8 are fixedly connected to the mounting frame 2 4; each air pipe 1 8 is respectively provided with three bronchi; and a number of light sensors 9 are fixedly connected to the mounting frame 2 4.

[0021] In order to prevent damage to the diffusion plate, the lower side of the lampshade 2 is made of rubber material.

[0022] It also includes a cylinder 21, a mounting plate 22 and a partition 23; two cylinders 21 are fixedly connected to the lower side of the mounting frame 24; the telescopic ends of all cylinders 21 are fixedly connected to the mounting plate 22; six partitions 23 are fixedly connected to the mounting plate 22 at equal intervals; each air pipe 8 is respectively located between two adjacent partitions 23; and each two light sensors 9 are respectively arranged between two adjacent partitions 23.

[0023] It also includes a second trachea 24; a second trachea 24 is respectively arranged on the left and right of each trachea 8; each second trachea 24 is fixedly connected to the mounting frame 2 4; and each second trachea 24 is respectively arranged with five bronchi.

[0024] The first step: open the door of the detection cabinet 10, place the diffuser plate on the two receiving platforms 5, and then close the door of the detection cabinet 10. The front side of the selected diffuser plate is flush with the front side of the receiving platform 5, and the back side of the diffuser plate is flush with the back side of the receiving platform 5. Control cylinder 1 6 to drive the rubber suction cup 7 to move downward, so that the rubber suction cup 7 contacts and adsorbs the diffuser plate, and then control cylinder 1 6 to drive the rubber suction cup 7 to move upward, so that the upper side of the diffuser plate is against the lower side of the lampshade 2, and the LED lamp 3 is powered on. The light emitted by the LED lamp 3 passes through the diffuser plate and shines on the light sensor 9. In this way, the light transmittance of the diffuser plate during normal use is tested.

[0025] Step 2: Connect the air pipe 8 to an external steam pump, and control the steam pump to discharge water vapor through the air pipe 8. The water vapor rises and contacts the diffuser plate, thus forming a layer of water film on the diffuser plate, simulating the actual environment, such as when used in a bathroom, the diffuser plate encounters water vapor condensation to form a water film; after the water film is formed, stop the steam input, and then power on the LED lamp 3. The light emitted by the LED lamp 3 passes through the diffuser plate and shines on the light sensor 9. The light sensor 9 tests the light transmittance of the diffuser plate in the presence of water film. The test results are compared with the light transmittance of the diffuser plate in normal use to obtain the effect of the water film on the light transmittance of the diffuser plate. The diffusers of different materials and surface treatments react differently to the water film. Testing the effect of the water film on the light transmittance of the diffuser plate can help evaluate which materials or treatment methods are more resistant to the influence of the water film, so as to select a more suitable one. Materials suitable for high humidity environments; the time for water vapor to be discharged through the air pipe 8 can be adjusted, thereby controlling the thickness of the water film on the diffuser plate to test the light transmittance of the diffuser plate under conditions of water film of different thicknesses; in order to test the light transmittance of the diffuser plate under conditions of water film of different thicknesses at one time to improve the test efficiency; the air cylinder 21 is controlled to drive the mounting plate 22 and the six partitions 23 to move upward, so that the six partitions 23 are in contact with the diffuser plate, and the six partitions 23 divide the diffuser plate into five areas, each of which is respectively provided with an air pipe 8 and two light sensors 9 under it, and the time for each air pipe 8 to pass water vapor is adjusted and controlled so that the thickness of the water film formed in each area of ​​each diffuser plate is different, and then the LED lamp 3 is powered on, and a diffuser plate is used to test the light transmittance of the diffuser plate under conditions of water film of different thicknesses at one time.

[0026] Step 3: After testing the transmittance, connect the air pipe 24 to an external air pump, and control the air pump to discharge hot air through the air pipe 24. The hot air rises and contacts the water film, causing the water film to evaporate and dissipate. The speed at which water films of different thicknesses dissipate is manually observed. Designers can use these data to select or develop diffusion plate materials suitable for specific environmental conditions to ensure that the product can quickly remove the water film during use and maintain good optical properties.

[0027] In addition, after the water film dissipates, the light transmittance of the diffuser plate is tested again, and the test results are compared with the previous results to determine whether the light transmittance of the diffuser plate changes after soaking and drying. If the change is obvious, it means that the material of the diffuser plate is unqualified and there are problems such as water absorption expansion and deformation.

[0028] The diffuser plate is used in environments containing corrosive liquids, such as chemical plants, sewage treatment facilities or offshore platforms. When used in these environments, the diffuser plate needs to have corrosion resistance. In order to test the corrosion resistance of the diffuser plate, the steam pump can also be controlled to discharge the corrosive vapor through the air pipe 8. The corrosive vapor rises and contacts the diffuser plate, so that the diffuser plate contacts the corrosive water vapor. The concentration of the corrosive water vapor sprayed from each air pipe 8 is different. The diffuser plate is then dried and the transmittance is tested. The test results are compared with the previous results to detect the corrosion resistance of the diffuser plate under different concentrations of corrosive water vapor. The light sensor 9 has corrosion resistance, which can prevent the corrosive vapor from contacting the light sensor 9 and causing damage to the light sensor 9.

[0029] The exhaust pipe on the upper part of the detection cabinet 10 is connected to the external exhaust gas treatment equipment. The corrosive steam used for detection is discharged into the external exhaust gas treatment equipment through the exhaust pipe on the upper part of the detection cabinet 10 for treatment, and then discharged into the atmosphere to avoid polluting the atmosphere.

[0030] Example 2 On the basis of Example 1, Figure 4-Figure 6 As shown, it also includes a mounting plate 2 31 and a high-light-transmittance glass 32; a mounting plate 2 31 is respectively arranged in front of and behind each light quantity sensor 9; each mounting plate 2 31 is welded to the mounting frame 2 4; a high-light-transmittance glass 32 is fixedly connected between every two mounting plates 2 31, and the high-light-transmittance glass 32 is located above the light quantity sensor 9, and the high-light-transmittance glass 32 is arranged to be inclined, and the right part of the high-light-transmittance glass 32 is lower than the left part; the right side of each high-light-transmittance glass 32 is in contact with the partition 1 23.

[0031] In order to dry the high light transmittance glass 32 , a bronchial tube of the air pipe 24 is arranged under each high light transmittance glass 32 .

[0032] In the second step of Example 1: after a thicker water film is formed on the diffuser plate, water droplets will drip downwards, and the water droplets will affect the test after dripping onto the light sensor 9; therefore, an inclined high-light-transmittance glass 32 is provided above the light sensor 9, and the right part of the high-light-transmittance glass 32 is lower than the left part. The dripping water droplets are blocked by the high-light-transmittance glass 32, and then flow to the right and flow away from above the light sensor 9, thereby preventing the water droplets from affecting the test results.

[0033] After the water drops flow on the high-light-transmittance glass 32, some tiny water droplets will remain. It is necessary to wait until the water droplets are dry before testing can be carried out, which takes a long time. In order to speed up the test, the air pump is controlled to pass hot air into the air pipe 24 below the high-light-transmittance glass 32, so that the hot air passes under the high-light-transmittance glass 32, and then the hot air contacts the high-light-transmittance glass 32 to heat the high-light-transmittance glass 32. The heat is then transferred to the remaining tiny water droplets, causing the tiny water droplets to evaporate quickly. After evaporation, testing can be carried out, thereby speeding up the test.

[0034] Example 3 On the basis of Example 2, Figure 7-Figure 8 As shown, it also includes a cylinder three 41, a U-shaped baffle plate 42 and a U-shaped baffle frame 45; a cylinder three 41 is fixedly connected to the opposite sides of the two mounting frames 1 respectively; a U-shaped baffle plate 42 is fixedly connected to the telescopic ends of the two cylinders three 41 respectively; a U-shaped baffle frame 45 is welded to each of the two U-shaped baffle plates 42 through an L-shaped plate; each U-shaped baffle frame 45 is slidably connected to a receiving platform 5 respectively.

[0035] It also includes a partition plate 2 43 ; six partition plates 2 43 are welded to the lower side of the U-shaped baffle plate 42 ; the partition plate 2 43 cooperates with the partition plate 1 23 .

[0036] In order to prevent the diffusion plate from being damaged, the second partition plate 43 is made of rubber material.

[0037] The front and rear parts of the baffles formed by the two U-shaped baffles 42 are respectively provided with five air outlet slots 44 .

[0038] After long-term use, lamps will age and have poor seals. Corrosive vapors will enter the lamps from the poor seals and then come into contact with the side of the diffuser facing the lamp. The side of the diffuser facing the lamp may be affected by the corrosive vapor, which in turn affects the light transmittance. In order to test the corrosion resistance of the side of the diffuser facing the lamp, the control cylinder 1 6 drives the rubber suction cup 7 and the diffuser plate to move downward, so that the diffuser plate is placed on the two receiving platforms 5 again, the front side of the diffuser plate is flush with the front side of the receiving platform 5, and the back side of the diffuser plate is flush with the back side of the receiving platform 5. Then the control cylinder 21 drives the mounting plate 1 22 and the six partitions 1 23 to move upward, so that the six partitions 1 23 come into contact with the diffuser plate, and the six partitions 1 23 The lower side of the diffuser plate is divided into five areas, and then, the two cylinders 3 41 are controlled to drive the two U-shaped baffles 42 and the U-shaped baffle frames 45 to move toward each other, so that the two U-shaped baffles 42 contact each other, and the two U-shaped baffle frames 45 contact each other, and the U-shaped baffle frames 45 are fitted with the lower side of the diffuser plate, and the lower side of the diffuser plate is isolated by the U-shaped baffle frames 45 to prevent the lower side of the diffuser plate from contacting with corrosive vapor. The partition 2 43 moves with the U-shaped baffle 42. After moving, the lower side of the partition 2 43 contacts the diffuser plate, and the front and rear of the partition 2 43 are in contact with the partition 1 23 and the U-shaped baffle frame 45. In this way, the partition 2 43 divides the upper side of the diffuser plate into multiple areas, and controls the steam pump to discharge the corrosive vapor through the air pipe 1 8, and the discharged corrosive vapor After the corrosive steam hits the lower side of the U-shaped baffle 45, it diffuses along the lower side of the U-shaped baffle 45 to the front and rear thereof, and then diffuses to the space formed by the U-shaped baffle 42, the partition 2 43 and the upper side of the diffusion plate, that is, contacts the upper side of the diffusion plate, so that the upper side of the diffusion plate contacts the corrosive steam. The U-shaped baffle 45 prevents the corrosive steam from contacting the middle part of the lower side of the diffusion plate, that is, the light-transmitting area, to prevent affecting the detection of the upper side of the diffusion plate; the concentration of the corrosive water vapor sprayed from each air pipe 1 8 is different, so that each area on the upper side of each diffusion plate contacts with corrosive water vapor of different concentrations; the excess corrosive water vapor in each area will be discharged through the air outlet groove 44, and the position of the air outlet groove 44 is higher than the lower end of the partition 2 43 and lower than the lower end of the diffusion plate. The upper side of the diffuser plate is thus prevented from mixing corrosive water vapor in a certain area into an adjacent area, causing changes in the concentration of corrosive water vapor in the adjacent area and affecting the test results; after the upper side of the diffuser plate reacts with the corrosive water vapor for a period of time, the air pipe 24 is connected to an external air pump, and the air pump is controlled to discharge hot air through the air pipe 24. The hot air is also diffused to the space formed by the U-shaped baffle 42, the partition 2 43 and the upper side of the diffuser plate to dry the diffuser plate, and then, the two cylinders 3 41 are controlled to drive the two U-shaped baffles 42 to move back to back and reset, and finally, the transmittance test is performed, and the test results are compared with the previous results, so as to detect the corrosion resistance of the side of the diffuser plate facing the lamp under different concentrations of corrosive water vapor.
