Water for inspection is stored in the water storage tank 6. A water leakage hole 47 is provided on the partition plate 7. A spray mechanism is arranged at the top of the inspection box 1. The spray mechanism comprises a nozzle 5. A plurality of nozzles 5 are arranged, and the plurality of nozzles 5 are evenly distributed at the inner top of the inspection box 1. A first water spray nozzle 5 is fixedly connected to the outer side of the top of the inspection box 1. Pump 3, the water outlet end of the first water pump 3 is connected to all the nozzles 5 through the pipe body, the water inlet end of the first water pump 3 is connected to the pumping pipe 4, the end of the pumping pipe 4 is connected to the inner bottom of the water storage tank 6, when the automobile LED lamp enters the detection box 1, the first water pump 3 pumps out the water in the water storage tank 6 through the pumping pipe 4, and then sprays the lamp body through the distributed nozzles 5 to detect whether the finished lamp body has water, and the sprayed water flows back to the water storage tank 6 through the leakage hole 47 on the partition plate 7, and then is pumped away through the pumping pipe 4 for recycling;

[0036] The detection box 1 is provided with a lamp pushing mechanism, which includes a first electric telescopic rod 2, one end of the first electric telescopic rod 2 is vertically connected to a telescopic connecting rod 24 through a rod body, the bottom end of the telescopic connecting rod 24 is fixedly connected to the detection box 1 through a cross plate, a first spring 25 is connected between the telescopic end and the fixed end of the telescopic connecting rod 24, the telescopic end of the first electric telescopic rod 2 is fixedly connected to a pushing plate 48, the pushing plate 48 is embedded in the side wall of the detection box 1, a shading mechanism is cooperatively provided between the pushing plate 48 and the detection box 1, the shading mechanism includes a connecting tube 11, the connecting tube 11 is fixedly connected to the outer wall of the detection box 1 near the pushing plate 48, an elastic corrugated telescopic tube 10 is connected between the inner wall of the connecting tube 11 and the pushing plate 48, and the elastic corrugated telescopic tube 10 is The black light-proof tube body is used to shield the position where the push plate 48 is connected to the detection box 1 to prevent the push plate 48 from moving away from the side wall of the detection box 1, causing the position to open and allow light to pass through. A light shielding plate 8 is fitted at the port of the connecting tube 11. The light shielding plate 8 is used to ensure that no external light passes through the position where the push plate 48 is located. The telescopic end of the first electric telescopic rod 2 passes through the light shielding plate 8, and a second spring 9 is connected between the telescopic end of the first electric telescopic rod 2 and the light shielding plate 8. The second spring 9 is stretchable. When the first electric telescopic rod 2 is extended, the push plate 48 moves laterally toward the inside of the detection box 1. During the movement, the light shielding plate 8 contacts the port of the connecting tube 11 and slides relative to the telescopic end of the first electric telescopic rod 2. The second spring 9 is stretched during this process. , generating a rebound force to ensure that the shading plate 8 fits the port of the connecting tube 11 to maintain the shielding; the bottom end of the pushing plate 48 is fixedly connected to a roller 49 through a bracket, and the roller 49 is on the partition plate 7. The partition plate 7 is movably connected to an inclined guide plate 50 through a rebound hinge. There are multiple inclined guide plates 50 distributed at equal intervals, and the connecting ends of the inclined guide plates 50 are spliced ​​on the end surface of the partition plate 7, and the rebound hinges are distributed on one side of the connecting end of the inclined guide plate 50, close to the position of the roller 49, that is, the inclined guide plate 50 can only rotate counterclockwise and cannot rotate clockwise. When the first electric telescopic rod 2 starts to extend, the pushing plate 48 moves horizontally into the detection box 1. During the horizontal movement, the roller 49 passes through the inclined guide plate 50 at each position in turn. When passing, the roller 49 rolls and rises along the inclined guide plate 50, and because the first electric telescopic rod 2 starts to extend, the pushing plate 48 moves horizontally into the detection box 1. During the horizontal movement, the roller 49 passes through the inclined guide plate 50 at each position in turn. When passing, the roller 49 rolls and rises along the inclined guide plate 50. An electric telescopic rod 2 is connected to the detection box 1 through a telescopic connecting rod 24 and a first spring 25, so the roller 49 drives the push plate 48 and the first electric telescopic rod 2 to rise together. When the roller 49 is separated from the inclined guide plate 50, it falls downward, that is, it bumps up and down. A lamp clamping mechanism is movably arranged on the push plate 48, and the lamp clamping mechanism includes a clamping plate 21. A through hole 12 is opened on the push plate 48, and the clamping plate 21 is connected with the through hole 12. A driving motor 22 is fixedly connected to one side of the bottom end of the push plate 48, and a rotating arm 23 is fixedly connected to the main shaft end of the driving motor 22. The end of the rotating arm 23 is fixedly connected to the clamping plate 21. A plurality of lamp fitting grooves 16 are opened on the clamping plate 21. The inner contour of the lamp fitting groove 16 is the same as the contour of the lamp, which is convenient for the lamp to be clamped.Each lamp fitting groove 16 is provided with a clamping mechanism, and the clamping mechanism includes a second electric telescopic rod 17, and the second electric telescopic rod 17 is a waterproof electric telescopic rod, and the model is DDTG13. The second electric telescopic rod 17 is fixedly connected in pairs at the upper and lower sides of the lamp fitting groove 16, and the telescopic end of the second electric telescopic rod 17 penetrates into the lamp fitting groove 16, and the telescopic end of the second electric telescopic rod 17 is fixedly connected with a clamping block 18. When the lamp is fitted in the lamp fitting groove 16, the paired second electric telescopic rod 17 is started to extend, so that the two clamping blocks 18 clamp the lamp and fix it in the lamp fitting groove 16. The lamp fitting groove 16 is also provided with an electric pole 13, and the electric pole 13 slides through the clamping plate 21, one end of which is in the lamp fitting groove 16, and the other end is on the outside of the clamping plate 21, and the electric pole 13 is connected to the clamping plate 21. A third spring 14 is connected between the plates 21, and the end of the power pole 13 outside the clamping plate 21 is connected with an electric wire, which passes through the sunshade 8 and is connected to an external power supply. The distribution position of the power pole 13 corresponds to the power connection position on the detection lamp, and the inner wall of the lamp fitting groove 16 is connected with a rubber convex ring 15 with the same contour shape as the detection lamp, and there is a concave-convex body on the rubber convex ring 15 that matches the concave-convex position of the edge of the detection lamp. When the lamp to be detected is fitted into the lamp fitting groove 16, the lamp contacts the rubber convex ring 15, and the power connection position on the detection lamp just touches the corresponding power pole 13, so that power is turned on, so as to light up the detection lamp, and the rubber convex ring 15 ensures that the space where the power pole 13 is located is sealed close to the inner side of the detection box 1, so as to prevent rainwater from entering the space where the power pole 13 is located during the rain detection process;

[0037] A detachable first glass window 26 is connected to the side of the detection box 1 away from the push plate 48. The first glass window 26 is light-transmissive. A first brightness sensor 27 aligned with the push plate 48 is installed on the outside of the first glass window 26. The sensing end of the first brightness sensor 27 is aligned with the first glass window 26 and is located in the installation space of the first glass window 26. The space is closed around to avoid the influence of external light. The first brightness sensor 27 is also externally connected to a related feedback host. When the lamp to be detected moves horizontally in the detection box 1 with the clamping plate 21 and performs rain detection, the powered lamp irradiates the first glass window 26, and the first brightness sensor 27 detects the brightness. When a part of the lamp is separated due to bumps during the detection process, causing water to enter, so that the lamp cannot light up normally, the brightness detected by the first brightness sensor 27 is lower than the set value, and feedback will be generated;

[0038] A surface wiping mechanism is provided on one side of the top of the detection box 1 close to the first electric telescopic rod 2, and the surface wiping mechanism includes a connecting cross plate 51, and a third electric telescopic rod 28 is vertically fixedly connected to the connecting cross plate 51, and the telescopic end of the third electric telescopic rod 28 vertically penetrates the connecting cross plate 51, and the telescopic end of the third electric telescopic rod 28 is horizontally fixedly connected to a lifting plate 31, and a plurality of grooves 44 are provided on the lifting plate 31, and the grooves 44 are matched with the lamps to be detected, so as to facilitate the insertion of the lamps, and an absorbent cotton pad 32 is fitted and connected to the inner side of each groove 44, and holes are distributed on the absorbent cotton pad 32, and an air cavity 34 is also provided in the lifting plate 31, and one end of the lifting plate 31 is fixedly connected to a hot air blower 36, and the model of the hot air blower 36 is HAM-G3B-11, and the hot air The air outlet end of the machine 36 is connected to the air cavity 34, and the bottom of the air cavity 34 is evenly provided with first air holes 35. The bottom of the lifting plate 31 is circumferentially provided with a plurality of second air holes 33 connected to the groove 44. A sleeve 29 is fixedly connected to one side of the bottom of the connecting cross plate 51, and a brightness sensing switch 30 is installed inside the sleeve 29. The third electric telescopic rod 28 and the hot air blower 36 are both electrically connected to the brightness sensing switch 30. A laser lamp 19 corresponding to the sleeve 29 is fixedly connected to the outer wall of the clamping plate 21, and a start switch button is provided on the laser lamp 19. The laser lamp 19 is at the same position as one of the second electric telescopic rods 17, and the telescopic end of the second electric telescopic rod 17 at this position is fixedly connected with a top block 20 aligned with the start switch button of the laser lamp 19.

[0039] When the empty clamping plate 21 needs to be placed on the car LED headlight for testing, the drive motor 22 is started, and the drive motor 22 drives the clamping plate 21 to rotate counterclockwise to a horizontal position through the rotating arm 23. At this time, the laser light 19 on the clamping plate 21 is aligned with the sleeve 29. Since no lamp is installed at this time, the second electric telescopic rod 17 is not extended, so the laser light 19 is not started to light up, so that the third electric telescopic rod 28 and the hot air blower 36 will not be triggered to start. When the lamp to be tested is placed in the lamp fitting groove 16, the drive motor 22 is controlled to drive the clamping plate 21 back to the horizontal position. The second electric telescopic rod 17 is operated to extend during the rotation, and the lamp is fixed and clamped by the clamping block 18. At this time, the corresponding second electric telescopic rod 17 drives the top block 20 to contact the start switch button on the laser lamp 19, and the laser lamp 19 emits a laser. It should be noted here that the position of the laser lamp 19 is not aligned with the first brightness sensor 27, that is, it will not affect the detection of the first brightness sensor 27. When the clamped car headlights still maintain the corresponding brightness after the rain and bump test, the drive motor 22 is controlled to drive the clamping plate 21 counterclockwise. When the second electric telescopic rod 17 is rotated to a horizontal position, that is, rotated out of the detection box 1, since the second electric telescopic rod 17 is still in an extended state at this time, the lamp is clamped by the clamping block 18, so the laser lamp 19 is still lit. Therefore, when the clamping plate 21 is rotated out and rotated to a horizontal position, the lit laser lamp 19 is aligned with the sleeve 29, and the light emitted enters the sleeve 29, and the brightness sensor switch 30 in the sleeve 29 is induced, so that the third electric telescopic rod 28 and the hot air blower 36 are started, and the third electric telescopic rod 28 is extended, so that the lifting plate 31 is lowered, and the lifting plate 31 is lowered to The mounting plate 21 is in a horizontal position, and the groove 44 on the lifting plate 31 is butted with the lamp housing placed on the mounting plate 21. The absorbent cotton pad 32 inside the groove 44 is convenient for absorbing water stains on the surface of the lamp housing. At the same time, the hot air blower 36 generates a hot air flow and passes into the air cavity 34. The hot air flow entering the air cavity 34 acts on the absorbent cotton pad 32 through the first air hole 35, which is convenient for drying the absorbent cotton pad 32, so that the moisture can be discharged from the second air hole 33 with the air flow, thereby completing the removal of moisture from the surface of the lamp housing to avoid affecting the observation of whether water has entered the lamp.

[0040] Removable second glass windows 42 are installed on both sides of the water tank 6. The second glass windows 42 on both sides are aligned horizontally. The second glass windows 42 can transmit light. A lighting lamp 43 is connected to the second glass window 42 on one side of the water tank 6. A second brightness sensor 41 is connected to the second glass window 42 on the other side of the water tank 6. A water inlet pipe 38 is fixedly connected to the outer side of the bottom of the water tank 6. The water inlet pipe 38 is connected to an external water source. A second water pump 37 electrically connected to the second brightness sensor 41 is installed on the water inlet pipe 38. The second brightness sensor 41 and the second water pump 37 are electrically connected through a delay circuit. A spherical body 39 connected to the water inlet pipe 38 is fixedly connected to the inner bottom of the water tank 6. Spray holes 40 are evenly opened on the spherical body 39. A drain pipe 45 is installed on one side of the bottom of the water tank 6. An electric valve 46 electrically connected to the second brightness sensor 41 is connected to the drain pipe 45.

[0041] The irradiation lamp 43 always emits light, which passes through the paired second glass windows 42 and the water in the water tank 6, and then relies on the second brightness sensor 41 to detect its brightness. When the water circulating in the water tank 6 becomes turbid to a certain extent, the brightness sensed by the second brightness sensor 41 will be lower than the corresponding value, so that the second brightness sensor 41 generates a signal feedback, so that the electric valve 46 opens, which facilitates the drainage pipe 45 to drain the water in the water tank 6. Then, after a certain period of time, the water in the water tank 6 is basically drained. At this time, the second water pump 37 is started, so that the external water source enters the spherical body 39 through the water inlet pipe 38, and then relies on the spray holes 40 on the spherical body 39 to spray out. Since the spray holes 40 are evenly distributed on the spherical body 39, they can be flushed in all directions and angles to facilitate cleaning of the inner wall of the water tank 6. When the turbidity of the water discharged from the drainage pipe 45 is reduced to a usable level, the electric valve 46 is closed, so that the water sprayed from the spray holes 40 remains in the water tank 6 for water storage.

[0042] A method for testing the quality of finished automotive LED lamps, the specific steps are as follows:

[0043] The first step is to start the drive motor 22, and the drive motor 22 drives the clamping plate 21 to rotate counterclockwise to a horizontal position through the rotating arm 23, and put the automobile lamp to be tested into the lamp fitting groove 16, and the lamp contacts the rubber convex ring 15, and the power connection position on the detection lamp just touches the corresponding power connection post 13, so that the power is turned on, so as to facilitate the detection of the lamp lighting, and the rubber convex ring 15 ensures that the space where the power connection post 13 is located is sealed close to the inner side of the detection box 1, and then the drive motor 22 is controlled to drive the clamping plate 21 to rotate, and during the rotation process, the paired second electric telescopic rods 17 are operated to extend, and the lamp is fixed and clamped by the clamping block 18, and one of the second electric telescopic rods 17 drives the connected top block 20 to touch the start switch button on the laser lamp 19, and the laser lamp 19 emits laser;

[0044] The second step is to start the first water pump 3. The first water pump 3 pumps out the water in the water tank 6 through the pumping pipe 4, and then sprays the lamp body through the distributed nozzles 5. At the same time, the first electric telescopic rod 2 is started. The first electric telescopic rod 2 is extended, so that the push plate 48 moves horizontally into the detection box 1. During the horizontal movement, the roller 49 passes through the inclined guide plate 50 at each position in turn. When passing, the roller 49 rolls and rises along the inclined guide plate 50. Since the first electric telescopic rod 2 is connected to the detection box 1 through the telescopic connecting rod 24 and the first spring 25, the roller 49 drives the push plate 48 and the first electric telescopic rod 2 to rise together. When the roller 49 is separated from the inclined guide plate 50, it falls downward, that is, it bumps up and down, thereby simulating the impact of the bumps on the car headlights during the driving process of the vehicle, and the water sprayed by the nozzle 5 simulates rainwater, and a water spraying experiment is carried out on the bumpy headlights to detect whether the parts connection position of the lamp will be separated under the bumpy condition, resulting in water entering;

[0045] Step 3: The powered lamp is irradiated towards the first glass window 26 during the moving process, and the first brightness sensor 27 detects the brightness. If a part of the lamp is separated due to the bump during the detection process, causing water to enter, so that the lamp cannot light up normally, the brightness detected by the first brightness sensor 27 is lower than the set value, and feedback is generated, which means that there is a problem in the detection process of the car headlights;

[0046] Step 4. After the clamped automobile headlight has been tested for rain and bumps, firstly, the first electric telescopic rod 2 is controlled to shrink and reset, and then the driving motor 22 is controlled to drive the clamping plate 21 to rotate counterclockwise to a horizontal position, that is, to rotate out of the test box 1. At this time, since the second electric telescopic rod 17 is still in an extended state and the lamp is clamped by the clamping block 18, the laser lamp 19 is still lit. Therefore, when the clamping plate 21 is rotated out and rotated to a horizontal position, the lit laser lamp 19 is aligned with the sleeve 29, and the light emitted is projected into the sleeve 29, and the brightness sensor switch 30 in the sleeve 29 generates an induction, so that the third electric telescopic rod 28 and the hot air blower 36 are started, and the third electric telescopic rod 28 is extended, so that The lifting plate 31 is lowered, and the lifting plate 31 is lowered to the clamping plate 21 in a horizontal position, and the groove 44 on the lifting plate 31 is docked with the lamp housing placed on the clamping plate 21, and the absorbent cotton pad 32 inside the groove 44 is convenient for absorbing water stains on the surface of the lamp housing. At the same time, the hot air blower 36 generates a hot air flow and passes into the air cavity 34. The hot air flow entering the air cavity 34 acts on the absorbent cotton pad 32 through the first air hole 35, which is convenient for drying the absorbent cotton pad 32, so that the moisture can be discharged from the second air hole 33 with the air flow, thereby completing the removal of moisture on the surface of the lamp housing to avoid affecting the observation of whether water has entered the lamp. Then the lamp is taken out to observe whether water has entered the lamp, and the detection is completed.
