Description

Technical Field

[0001] This utility model relates to the field of H1 bulb technology, specifically to a sealing detection device for automotive H1 bulbs. Background Technology

[0002] In automotive lighting systems, H1 bulbs are commonly used lighting components, and their sealing performance is crucial. Poorly sealed H1 bulbs are susceptible to the intrusion of external moisture, dust, and other impurities during use, which can lead to filament short circuits, reduced luminous efficiency, or even bulb damage, seriously affecting the safety of nighttime driving and the lifespan of the lighting system.

[0003] Currently, traditional methods for testing the seal of automotive H1 bulbs mainly include immersion testing and smear testing. Immersion testing involves submerging the H1 bulb in water and observing the formation of bubbles to determine its seal performance. However, this method is not only inefficient but also prone to secondary contamination of the H1 bulb and struggles to accurately detect minute leaks. Smear testing involves applying a specific testing liquid to the seal of the H1 bulb and observing changes in the liquid to assess the seal. This method is cumbersome, its results are highly susceptible to human error, and its accuracy is difficult to guarantee.

[0004] With the rapid development of the automotive industry, higher requirements have been placed on the accuracy and efficiency of H1 bulb sealing inspection. In order to quickly and accurately detect the sealing performance of H1 bulbs, overcome the shortcomings of traditional inspection methods, and improve inspection efficiency and accuracy, we propose an automotive H1 bulb sealing inspection device.

[0014] This invention provides a sealing detection device for automotive H1 bulbs. Compared with the prior art, it has the following advantages:

[0015] The vehicle H1 bulb sealing detection device intermittently rotates the rotating disk through a motor. When the rotating disk is stationary, the H1 bulb remains stationary. At this time, a group of H1 bulbs are located directly below the detection cover.

Detailed Embodiment

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0024] Please see Figure 1-6 This utility model provides a technical solution: a sealing test device for automotive H1 bulbs, including a workbench 1, a rotating cylinder 12 rotatably passing through the top of the workbench 1, a rotating disk 2 fixedly connected to the top of the rotating cylinder 12, a number of placement plates 3 fixedly connected to the top of the rotating disk 2, a drive assembly for intermittently rotating the rotating disk 2, a test assembly for sealing test of H1 bulbs, and a screening assembly for rejecting H1 bulbs with unqualified sealing performance.

[0025] The detection assembly includes a first support frame 5, which is fixedly connected to the top of the workbench 1. A top plate 25 is fixedly connected to the top of the first support frame 5. A lifting cylinder 7 is fixedly installed on the top of the top plate 25. A first slider 23 is fixedly connected to the side of the first support frame 5 near the lifting cylinder 7. A first slide rail 24 is slidably sleeved on the outside of the first slider 23. A first mounting frame 26 is fixedly connected to the side of the first slide rail 24 away from the first slider 23. A detection cover 8 is fixedly installed at the bottom of the first mounting frame 26. The output end of the lifting cylinder 7 is fixedly connected to the first mounting frame 26.

[0026] The detection cover 8 is provided with a connection port, a sealing rubber gasket is fixedly connected to the bottom of the detection cover 8, and a pressure sensor is fixedly installed on the inner wall of the detection cover 8.

[0027] In use, the H1 bulb is placed in the placement cavity on the placement plate 3. The drive assembly drives the rotating disk 2 to rotate intermittently. When the rotating disk 2 is stationary, the placement plate 3 remains stationary, and the H1 bulb remains stationary. At this time, a set of H1 bulbs is located directly below the detection cover 8. The lifting cylinder 7 is activated to move the first mounting bracket 26 downward, which in turn moves the detection cover 8 downward, causing the sealing rubber pad at the bottom of the detection cover 8 to press the H1 bulb tightly. Then, a certain amount of gas is injected into the detection cover 8 through the connection port and maintained for a period of time. During this period, the air pressure sensor detects the air pressure inside the detection cover 8. If the air pressure in the detection cover 8 remains unchanged, the sealing performance of this H1 bulb is qualified. If the air pressure in the detection cover 8 decreases, the sealing performance of this H1 bulb is unqualified and it will be rejected by the screening assembly. After the test is completed, the lifting cylinder 7 drives the detection cover 8 to rise, the rotating disk 2 rotates, and moves the next set of H1 bulbs to below the detection cover 8.

[0028] The screening assembly includes a second support frame 6, which is fixedly connected to the top of the workbench 1. A connecting frame 21 is provided on the rear side of the second support frame 6. A movable cylinder 20 is fixedly installed on the connecting frame 21. A second mounting frame 22 is fixedly connected to the output end of the movable cylinder 20. A gripper cylinder 19 is fixedly installed at the bottom of the second mounting frame 22. A connecting mechanism is installed on the connecting frame 21 to make the gripper cylinder 19 and the detection cover 8 move up and down synchronously.

[0029] The connecting mechanism includes a transmission frame 18, which is fixedly connected to the rear side of the connecting frame 21. The end of the transmission frame 18 away from the connecting frame 21 is fixedly connected to the first mounting frame 26. A second slider 27 is fixedly connected to the side of the second support frame 6 near the connecting frame 21. A second slide rail 28 is slidably sleeved on the outside of the second slider 27. The side of the second slide rail 28 away from the second slider 27 is fixedly connected to the connecting frame 21.

[0030] Under the action of the transmission frame 18, the gripper cylinder 19 and the detection cover 8 move up and down synchronously. The air pressure sensor sends a signal to control the moving cylinder 20. When the tested H1 bulb is qualified, the moving cylinder 20 does not start. When the tested H1 bulb is unqualified, the moving cylinder 20 starts and drives the gripper cylinder 19 to move above the placement plate 3. As the rotating disk 2 rotates, the unqualified H1 bulb moves below the gripper cylinder 19. The gripper cylinder 19 descends with the detection cover 8 and picks up the unqualified H1 bulb. Then the moving cylinder 20 drives the gripper cylinder 19 to reset. The gripper cylinder 19 releases the unqualified H1 bulb, thereby eliminating the unqualified H1 bulb.

[0031] The drive assembly includes a rotating plate 14, which is fixedly sleeved on the outside of the rotating cylinder 12. A partition plate 11 is fixedly connected to the inner wall of the worktable 1. A motor 10 is fixedly installed at the bottom of the partition plate 11. A drive plate 15 is fixedly connected to the output end of the motor 10. A locking block 16 and a drive pin 17 are fixedly connected to the top of the drive plate 15. Several sets of locking grooves 9 corresponding to the locking blocks 16 are spaced apart on the rotating plate 14. Several sets of drive grooves 29 corresponding to the drive pins 17 are spaced apart on the rotating plate 14.

[0032] The motor 10 drives the drive plate 15 to rotate, which in turn drives the locking block 16 and the drive pin 17 to rotate. When the locking block 16 is in the locking groove 9, the rotating plate 14 does not rotate. Each time the drive pin 17 is engaged in the drive groove 29, it will drive the rotating plate 14 to rotate by a certain angle, so that the rotating disk 2 rotates by a certain angle, thereby realizing the intermittent rotation of the rotating disk 2.

[0033] A connecting cylinder 13 is fixedly connected to the top of the partition plate 11, and a rotating cylinder 12 is rotatably sleeved on the outside of the connecting cylinder 13. A mounting plate 4 is fixedly connected to the top of the connecting cylinder 13. It is used to install air pumps, control boxes, etc.

[0034] Working principle: When in use, the H1 bulb is placed in the placement cavity on the placement plate 3. The motor 10 drives the drive plate 15 to rotate, which in turn drives the locking block 16 and the drive pin 17 to rotate. When the locking block 16 is in the locking groove 9, the rotating plate 14 does not rotate. Each time the drive pin 17 is engaged in the drive groove 29, it will drive the rotating plate 14 to rotate by a certain angle, so that the rotating disk 2 rotates by a certain angle, thereby realizing the intermittent rotation of the rotating disk 2. When the rotating disk 2 is stationary and the placement plate 3 remains stationary, the H1 bulbs remain stationary. At this time, a set of H1 bulbs is located directly below the detection cover 8. The lifting cylinder 7 is activated to move the first mounting bracket 26 downward, which in turn moves the detection cover 8 downward, causing the sealing rubber pad at the bottom of the detection cover 8 to press the H1 bulbs tightly. Then, a certain amount of gas is injected into the detection cover 8 through the connection port and maintained for a period of time. During this period, the air pressure sensor detects the air pressure inside the detection cover 8. If the air pressure in the detection cover 8 remains unchanged, the sealing performance of this H1 bulb is qualified. If the air pressure in the detection cover 8 decreases, the sealing performance of this H1 bulb is unqualified. After the test is completed, the lifting cylinder 7 moves the detection cover 8 upward, the rotating disk 2 rotates, and moves the next set of H1 bulbs to below the detection cover 8. Under the action of the transmission frame 18, the gripper cylinder 19 and the detection cover 8 move up and down synchronously. The air pressure sensor sends a signal to control the moving cylinder 20. When the tested H1 bulb is qualified, the moving cylinder 20 does not start. When the tested H1 bulb is unqualified, the moving cylinder 20 starts and drives the gripper cylinder 19 to move above the placement plate 3. As the rotating disk 2 rotates, the unqualified H1 bulb moves below the gripper cylinder 19. The gripper cylinder 19 descends with the detection cover 8 and picks up the unqualified H1 bulb. Then the moving cylinder 20 drives the gripper cylinder 19 to reset. The gripper cylinder 19 releases the unqualified H1 bulb, thereby removing the unqualified H1 bulb.
