[0020] Specifically, such as Figure 1-Figure 3 as well as Figure 5 As shown, the lower end of the storage plate 2 is provided with two groups of symmetrically distributed first guide blocks 16, and the upper end of the fixing base 1 is provided with first guide grooves 5 at positions corresponding to the two groups of the first guide blocks 16; In this embodiment, the second guide block 20 slides inside the first guide groove 5 to assist the storage plate 2 in moving.

[0021] Specifically, such as Figure 1 and Figure 5 As shown, a clamping assembly is provided on one side wall of the storage plate 2 for clamping the lamp body 19 , and the clamping assembly includes a placement plate 4 connected to the side wall of the storage plate 2 ; A clearance groove 22 is formed at the center of a side wall of the storage plate 2 facing the illuminometer probe 3. A third transmission screw 23 is rotatably provided inside the clearance groove 22. A second motor 12 is installed at the upper end of the storage plate 2 at a position corresponding to the third transmission screw 23. One end of the third transmission screw 23 passes through the storage plate 2 and is connected to the output end of the second motor 12. A third slider 24 is slidably disposed inside the clearance groove 22 , and the third slider 24 is screwed to the third transmission screw 23 , and one end of the third slider 24 away from the third transmission screw 23 passes through the clearance groove 22 and is connected to the abutment block 18 ; In this embodiment: the third transmission screw 23 is driven to rotate by the second motor 12, and then the third slider 24 is driven to move up and down along the clearance groove 22. When the third slider 24 moves, it drives the supporting block 18 to move relative to the placement plate 4, thereby clamping the lamp body 19 on the placement plate 4.

[0022] Specifically, such as Figure 9 As shown, the side walls of the abutting block 18 are each provided with a second receiving groove 34, and an extrusion plate 36 is provided inside each of the second receiving grooves 34. A second return spring 35 is provided between the end of each extrusion plate 36 and the inner side wall of the corresponding second receiving groove 34, and the extrusion plate 36 is elastically connected to the abutting block 18 through the second return spring 35; In this embodiment, when the supporting block 18 moves toward the lamp body 19 driven by the third slider 24, the elastically arranged extrusion plate 36 will first contact the side wall of the lamp body 19 and squeeze the lamp body 19 downward to achieve the limiting fixation of the lamp body 19.

[0023] Specifically, such as Figure 12-13 As shown, a fourth receiving groove 41 is formed at the upper end of the placement plate 4 at a position corresponding to the position of the lamp body 19. Two groups of cleaning plates 28 are slidably arranged inside the fourth receiving groove 41. Multiple groups of spaced-apart third return springs 42 are provided between the lower ends of the two groups of cleaning plates 28 and the inner bottom end of the fourth receiving groove 41. The two groups of cleaning plates 28 are elastically connected to the placement plate 4 via the multiple groups of third return springs 42. A fourth air bag 43 is provided between the lower end of the two groups of cleaning plates 28 and the inner bottom end of the fourth receiving groove 41; A first airbag 25 is provided between the lower end of the third slider 24 and the inner bottom end of the clearance groove 22. A first exhaust pipe 26 is provided between the first airbag 25 and the two groups of the fourth airbags 43. The first airbag 25 is connected to the two groups of the fourth airbags 43 through the first exhaust pipe 26. In this embodiment: when the supporting block 18 moves downward, it drives the third slider 24 to compress the first airbag 25. The gas inside the first airbag 25 is discharged to the inside of the fourth airbag 43 through the first exhaust pipe 26. The fourth airbag 43 expands and pushes the cleaning plate 28 out from the inside of the fourth receiving groove 41. When the cleaning plate 28 is extended, the surface of the lamp body 19 can be cleaned to prevent dust from adhering to the surface of the lamp body 19 and affecting the photometric test of the lamp body 19.

[0024] Specifically, such as Figure 7-Figure 8 as well as Figure 10-11 As shown, a connecting plate 29 is installed at the upper end of the placement plate 4 at a position corresponding to the cleaning plate 28. A limiting groove 30 is provided on the side wall of the connecting plate 29 facing the cleaning plate 28. A scraper 33 is slidably provided inside the limiting groove 30. The scraper 33 is located directly above the cleaning plate 28. A first return spring 32 is provided between a side wall of the scraper 33 and the inner top of the limiting groove 30 , and the scraper 33 is elastically connected to the connecting plate 29 via the first return spring 32 ; A second air bag 31 is provided between the other side wall of the scraper 33 and the inner bottom end of the limiting groove 30; A third receiving groove 37 is formed on the side wall of the storage plate 2 at a position corresponding to the abutting block 18. A trigger block 38 is disposed inside the third receiving groove 37. A third airbag 39 is disposed between an end of the trigger block 38 and the inner side wall of the third receiving groove 37. A second exhaust duct 40 is formed between the third airbag 39 and the corresponding second airbag 31. When the third slider 24 is pressed down on the first airbag 25 by the supporting block 18, the supporting block 18 will squeeze the trigger block 38 at the same time. When the trigger block 38 is squeezed, the third airbag 39 is compressed. At this time, the gas inside the third airbag 39 is discharged to the inside of the second airbag 31 through the second exhaust pipe 40. The second airbag 31 expands and pushes the elastically arranged scraper 33 to move up to the upper end of the cleaning plate 28. When the cleaning plate 28 finishes cleaning the surface of the lamp body 19, the supporting block 18 moves up. At this time, the first airbag 25 is no longer compressed, and the elastically arranged cleaning plate 28 is reset. The swept dust falls to the surface of the placement plate 4. When the cleaning plate 28 is reset, the supporting block 18 is staggered with the trigger block 38. At this time, the third airbag 39 is no longer compressed. Under the action of the first reset spring 32, the scraper 33 slides along the surface of the placement plate 4 to sweep away the dust that falls on the surface of the placement plate 4.

[0025] Specifically, such as Figure 3-Figure 4 As shown, a second chute 7 is formed on the upper end surface of the fixed base 1 away from the storage plate 2. A second transmission screw 15 is rotatably provided inside the second chute 7. A first motor 11 is installed at a position on the side wall of the fixed base 1 corresponding to the position of the second transmission screw 15, and one end of the second transmission screw 15 passes through the fixed base 1 and is connected to the output end of the first motor 11. A first slider 17 is slidably provided inside the second chute 7. The first slider 17 is screwed to the second transmission screw 15. A fixing plate 9 is provided at the upper end of the second transmission screw 15. Two groups of symmetrically distributed first guide blocks 16 are installed at the lower end of the fixing plate 9. A second guide groove 8 is formed at the upper end of the fixing base 1 at the positions corresponding to the two groups of first guide blocks 16. An automatic telescopic rod 10 is provided at the upper end of the fixing plate 9, and the illuminometer probe 3 is connected to the output end of the automatic telescopic rod 10; In this embodiment, the second transmission screw 15 is driven to rotate by the first motor 11, thereby driving the fixed plate 9 to move along the second chute 7. When the second chute 7 moves, the illuminance meter probe 3 on the second chute 7 can test the lamp body 19 of any width, and the setting of the automatic telescopic rod 10 can lift the height of the illuminance meter probe 3 to adapt to the lamp body 19 of any height.

[0026] This solution is specifically as follows: the lamp body 19 is placed on the placement plate 4, and then the second motor 12 is started. The second motor 12 drives the third transmission screw 23 to rotate, thereby driving the third slider 24 to move up and down along the clearance groove 22. When the third slider 24 moves, it drives the abutting block 18 to move relative to the placement plate 4. When the abutting block 18 is driven by the third slider 24 and moves toward the lamp body 19, the elastically arranged squeezing plate 36 will first contact the side wall of the lamp body 19 and squeeze the lamp body 19 downward to achieve the limited fixation of the lamp body 19; When the abutting block 18 moves downward, it drives the third slider 24 to compress the first airbag 25. The gas inside the first airbag 25 is discharged into the fourth airbag 43 through the first exhaust pipe 26. The fourth airbag 43 expands, pushing the cleaning plate 28 out of the fourth receiving groove 41. When the cleaning plate 28 is extended, it can clean the surface of the lamp body 19 to prevent dust from adhering to the surface of the lamp body 19 and affecting the photometric test of the lamp body 19. When the abutting block 18 drives the third slider 24 to press the first airbag 25 downward, the abutting block 18 will squeeze the trigger block 38 at the same time. When the trigger block 38 is squeezed, the third airbag 39 is compressed. At this time, the gas inside the third airbag 39 is discharged into the second airbag 31 through the second exhaust pipe 40. The second airbag 31 expands and pushes the elastic scraper 33 to move up to the upper end of the cleaning plate 28. When the cleaning plate 28 finishes cleaning the surface of the lamp body 19, the abutting block 18 moves up. At this time, the first airbag 25 is no longer compressed, and the elastic cleaning plate 28 is reset. The swept dust falls onto the surface of the placement plate 4. When the cleaning plate 28 is reset, the abutting block 18 and the trigger block 38 are staggered. At this time, the third airbag 39 is no longer compressed. Under the action of the first return spring 32, the scraper 33 slides along the surface of the placement plate 4 to sweep away the dust that falls onto the surface of the placement plate 4. Finally, start the lamp body 19, and then start the illuminometer probe 3. The brightness of the lamp body 19 is collected through the illuminometer probe 3. The position of the illuminometer probe 3 relative to the lamp body 19 can be adjusted through the cooperation of the first motor 11 and the automatic telescopic rod 10 to collect the brightness of the light at any position of the lamp body 19, or the third motor 13 can be started to adjust the brightness of the light at any distance between the lamp body 19 and the illuminometer probe 3.
