Description

Technical Field

[0001] The utility model belongs to the technical field of visual detection of air tightness of automobile lamps, and in particular relates to a visual detection device for air tightness of automobile lamps. Background Art

[0002] A test method in which compressed air (or ammonia, Freon, helium, halogen gas, etc.) is pressed into a container, and the pressure difference between the gas inside and outside the container is used to check for leaks. An airtightness test requires an airtightness tester, which is a device specially used for sealing test of cavity mechanical products. There are many ways to test the airtightness of automotive lamps. Generally, the lamps are pressed together and then inflated to determine the airtightness of the automotive lamps.

[0003] The existing method of testing the air tightness of lamps is to inject compressed air into the air holes of the lamps, and then submerge the lamps into water to observe the bubbles around the lamps for judgment. However, the air pipe is connected in advance before the lamps are submerged in water, and then the external clamp is manually picked up and the lamp is pressed into the water. When pressed into the water, the air pipe and the clamp may be entangled with each other, making the testing operation inconvenient. At the same time, the entangled air pipe may loosen at the air holes of the lamps, affecting the testing effect.

[0004] To this end, we propose an intuitive detection device for air tightness of automobile lamps to solve the above problems. Utility Model Content

A flip assembly is provided on the connecting shaft on one side of the mounting plate 3, which flips the mounting plate 3 as the mounting plate 3 moves. The lamp is installed on the mounting plate 3 through the clamping assembly through the provided mounting plate 3, the driving assembly, the clamping assembly and the flipping assembly. Then, as the driving assembly drives the mounting plate 3 to move downward, at the same time, as the mounting plate 3 moves, the flipping assembly on one side of the connecting shaft is made to rotate the mounting plate 3 180 degrees, and the part of the lamp to be inspected is downward, so that the lamp is submerged as a whole in water, and then the air pipe is passed through the connecting groove 4 to connect with the air hole on one side of the lamp, and air is injected into the water through the air pipe. By observing whether there are bubbles in the water, the air tightness of the lamp is detected.

[0023] Reference Figure 2The driving assembly includes a lead screw 11 and a guide rod 12. The lead screw 11 is rotatably connected to one side of the mounting frame 2, and the guide rod 12 is fixedly connected to the other side of the mounting frame 2. One connecting block 10 is threadedly sleeved on the lead screw 11, and the other connecting block 10 is slidably sleeved on the guide rod 12. The top surface of the mounting frame 2 is equipped with a motor 5 connected to the lead screw 11. The lead screw 11 is driven to rotate by the motor 5. Due to the rotation of the lead screw 11, the connecting blocks 10 at both ends of the mounting plate 3 will synchronously lower the mounting plate 3, thereby moving the lamp installed on the mounting plate 3 into the water tank 1.

[0024] Reference Figure 3 A movable groove is provided on one side of the top surface of the mounting plate 3, and the clamping assembly includes a fixed plate 7 and a movable plate 8. The fixed plate 7 is fixedly connected to the top surface of the mounting plate 3, and the movable plate 8 is slidably installed in the movable groove. A threaded rod 13 threadedly sleeved with the movable plate 8 is rotatably connected in the movable groove. The air hole of the lamp is placed in the connecting groove 4, and then one side of the lamp is close to the fixed plate 7. The movable plate 8 is moved closer to the side of the fixed plate 7 by twisting the threaded rod 13, and the lamp is clamped and fixed by the fixed plate 7 and the movable plate 8.

[0025] Reference Figure 4-Figure 5 The flip assembly includes a gear 9, which is fixedly connected to a connecting shaft on one side of the mounting plate 3. A rack 14 meshing with the gear 9 is provided on the inner wall of one side of the water tank 1. As the mounting plate 3 descends, the gear 9 on the connecting shaft on one side of the mounting plate 3 meshes with the rack 14. When the mounting plate 3 descends synchronously, the mounting plate 3 is flipped over, with the side of the lamp to be inspected facing downward.

[0026] Reference Figure 5 The inner wall of the water tank 1 is fixedly connected with a connecting plate 15 , and the rack 14 is slidably sleeved on the connecting plate 15 , so that the rack 14 slides on the connecting plate 15 and increases the extension length of the rack 14 .

[0027] Reference Figure 5 The upper and lower ends of the rack 14 are fixedly connected with a push plate 16 that abuts against the gear 9. As the gear 9 engages with the rack 14, after the mounting plate 3 rotates 180 degrees, the gear 9 abuts against the push plate 16 at the bottom of the rack 14. As the mounting plate 3 continues to descend, the gear 9 pushes the rack 14 downward, keeping the mounting plate 3 180 degrees from flipping over again, so that the lamp can be steadily submerged in the water.

[0028] Working principle:

[0029] The side of the lamp with the air hole is directed toward the connecting groove 4 of the mounting plate 3, and one side of the lamp is pressed against the fixing plate 7. Then, the threaded rod 13 is screwed to make the movable plate 8 approach the lamp, so as to fix the lamp. Then, the lead screw 11 is driven by the motor 5 to move the mounting plate 3 to the bottom of the water tank 1. As the mounting plate 3 moves, the gear 9 on one side of the mounting plate 3 meshes with the rack 14, and the mounting plate 3 is flipped 180 degrees, with the side of the lamp to be tested facing downward. As the mounting plate 3 continues to move, the gear 9 abuts against the push plate 16 at the bottom of the rack 14, pushing the rack 14 to slide along the connecting plate 15, keeping the mounting plate 3 at 180 degrees. After the lamp is submerged in the water, it is installed in the air hole of the lamp through the connecting groove 4 through an external air pipe and compressed air is injected. Whether there are bubbles in the water of the lamp is detected through the observation window 6 on one side of the water tank 1.

[0030] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes within the technical scope disclosed by the present invention according to the technical scheme and the utility model concept of the present invention, which should be covered by the protection scope of the present invention.
