Both ends of the rotating shaft extend through the inside of the protective cover to the outside and are coaxially fixed with gears. A fixing rod is fixed to the outside of the gears. A spring is fixed to the outside of the fixing rod. One end of the spring is fixedly connected to the lower part of the outside of the protective cover. A cover plate is fixed between the two fixing rods. A movable groove is opened on the outside of both side plates. A rack is slidably connected to the inside of the movable groove. A baffle is fixed to one side of the rack.
[0006] As a preferred embodiment of this invention, the groove includes two horizontal sections and one V-shaped section.
[0007] As a preferred embodiment of this invention, the position of the first movable base is higher than that of the movable plate.

[0014] 2. In this automotive LED module production and testing device, when the LED module moves to the testing area, the first or second movable base pushes the rack along the movable groove via a baffle. The rack drives the gear to rotate, and the gear lowers the cover plate and compresses the spring via a fixed rod, causing the cover plate to close with the protective cover, blocking the strong light from the LED module. When the first or second movable base disengages from the baffle, the cover plate automatically rises under the push of the spring. Through the above process, the problem of the strong light emitted by the LED module during long-term operation easily damaging the eye health of the workers is solved. Attached Figure Description

Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.
[0023] Please see Figures 1 to 4This utility model provides a technical solution: an automotive LED module production and testing device, comprising two supports 1, two side plates 2 fixed between the two supports 1, a sliding groove 3 on the outer side of each side plate 2, a transmission belt 4 on the opposite side of each side plate 2, four transmission wheels 5 frictionally driven on the inner side of the transmission belt 4, one side of each of the four transmission wheels 5 being rotatably connected to the outer side of the side plate 2, a transmission shaft 6 coaxially fixed between the two opposite transmission wheels 5, a first movable base 7 and a movable plate 8 slidably connected between the two side plates 2, a connecting rod 9 slidably connected inside the movable plate 8, sliding rods 10 fixed on both sides of the connecting rod 9, the outer side of the sliding rod 10 being slidably connected to the inner side of the sliding groove 3, a second movable base 11 fixed on the top surface of the connecting rod 9, a motor 12 fixed on the outer side of one of the side plates 2, the output end of the motor 12 being coaxially fixedly connected to one end of the rotating shaft of one of the transmission wheels 5, a protective cover 13 fixed between the two side plates 2, an illuminance meter 21 fixed on the inner side of the protective cover 13, and the protective cover 13... A rotating shaft 14 is rotatably connected to the inner side of the protective cover 13. Both ends of the rotating shaft 14 extend through the inner side of the protective cover 13 to the outside and are coaxially fixed with gears 15. A fixing rod 16 is fixed to the outside of the gears 15, and a spring 22 is fixed to the outside of the fixing rod 16. One end of the spring 22 is fixedly connected to the lower part of the outer side of the protective cover 13. A cover plate 17 is fixed between the two fixing rods 16. Movable grooves 18 are opened on the outer sides of the two side plates 2. A rack 19 is slidably connected to the inner side of the movable groove 18. A rack 19 is fixed on one side of the rack 19. The baffle 20 and the slide 3 include two horizontal sections and one V-shaped section. The position of the first movable base 7 is higher than that of the movable plate 8. The bottom surface of the first movable base 7 is fixedly connected to the top surface of the two transmission belts 4. The top surface of the movable plate 8 is fixedly connected to the bottom surface of the two transmission belts 4. The height of the second movable base 11 is the same as that of the first movable base 7. The cover plate 17 has an arc-shaped structure. The center of the cover plate 17 coincides with the center of the gear 15. The top surface of the rack 19 meshes with the outer circumference of the gear 15.
[0024] While the LED module on the first movable base 7 is being tested by the illuminance meter 21, the operator fixes the next LED module on the second movable base 11 and turns on the power. This allows the testing of the previous LED module and the fixing and power-on of the next LED module to proceed simultaneously, thereby accelerating production efficiency. After the previous LED module is tested, the motor 12 drives the transmission belt 4 to rotate via the transmission wheel 5. The transmission belt 4 drives the first movable base 7 and the movable plate 8 to move towards the center. During this process, the sliding rod 10 on the connecting rod 9 moves along the slide groove 3. When the sliding rod enters the V-shaped section, the sliding rod 10 drives the connecting rod 9 and the second movable base 11 to gradually move downwards, thus offsetting them from the first movable base 7 in height. When the sliding rod passes the lowest point of the V-shaped section, the sliding rod 10 drives the connecting rod 9 and the second movable base 11 to gradually move upwards, thus aligning the second movable base 11 with the first movable base 7 in height. Afterwards, the second movable base 11 moves to the testing position. The first movable base 7 moves to the workstation. Through the above process, the testing of the previous LED module and the fixing and power-on of the next LED module can be carried out simultaneously, thereby speeding up production efficiency and solving the problem of low work efficiency caused by the need for manual power-on and handheld illuminance meters to test the light output, luminous efficacy, color temperature, and color rendering index of LED modules. When the LED module moves to the testing position, the first movable base 7 or the second movable base 11 pushes the rack 19 along the movable groove 18 through the baffle 20. The rack 19 drives the gear 15 to rotate. The gear 15 lowers the cover plate 17 and compresses the spring 22 through the fixing rod 16, so that the cover plate 17 and the protective cover 13 are closed, blocking the strong light of the LED module. When the first movable base 7 or the second movable base 11 is separated from the baffle 20, the cover plate 17 is automatically raised under the push of the spring 22. Through the above process, the problem that the strong light emitted by the LED module during long-term operation can easily damage the eye health of the workers is solved.
[0025] The specific usage and function of this embodiment: When the LED module on the first movable base 7 is being tested by the illuminance meter 21, the operator fixes the next LED module on the second movable base 11 and turns on the power, so that the testing of the previous LED module and the fixing and power-on of the next LED module can be carried out simultaneously, thereby accelerating production efficiency. After the testing of the previous LED module is completed, the motor 12 drives the transmission belt 4 to rotate through the transmission wheel 5. The transmission belt 4 drives the first movable base 7 and the movable plate 8 to move towards the center. During this process, the slide rod 10 on the connecting rod 9 moves along the slide groove 3. When the slide bar enters the V-shaped section, the slide bar 10 drives the connecting rod 9 and the second moving base 11 to gradually move downward, thus offsetting them in height from the first moving base 7. After the slide bar passes the lowest point of the V-shaped section, the slide bar 10 drives the connecting rod 9 and the second moving base 11 to gradually move upward, thus aligning the second moving base 11 with the first moving base 7 in height. Then, the second moving base 11 moves to the inspection point, and the first moving base 7 moves to the workstation. Through the above process, the inspection of the previous LED module and the fixing and power-on of the next LED module can be carried out simultaneously, thereby speeding up production efficiency.
[0026] When the LED module moves to the detection area, the first movable base 7 or the second movable base 11 pushes the rack 19 along the movable groove 18 through the baffle 20. The rack 19 drives the gear 15 to rotate. The gear 15 lowers the cover plate 17 and compresses the spring 22 through the fixed rod 16, so that the cover plate 17 and the protective cover 13 are closed, blocking the strong light of the LED module. When the first movable base 7 or the second movable base 11 is separated from the baffle 20, the cover plate 17 is automatically raised under the push of the spring 22.
[0027] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
