Description

[0001] This application is a divisional application of the application filed on October 8, 2023, with application number 202311288436.0 and invention name “An airtightness testing system for intelligent manufacturing of automotive headlights”. Technical Field

[0002] The present invention relates to the technical field of new energy vehicles, and in particular to an airtightness testing system for intelligent manufacturing of automobile lamps. Background Art

[0003] With the rapid development of my country's new energy field, the use of new energy vehicles is becoming more and more widespread. In the production process of new energy vehicles, the processing of headlights accounts for a certain proportion. Most headlights are placed outside and are easily invaded by rain. Therefore, the air tightness requirements of headlights are relatively high. In the manufacturing process of headlights, it is usually necessary to conduct air tightness tests on them. However, the existing air tightness test system has the following problems when used:

[0004] For the air tightness test of car lights, the existing technologies are mostly divided into two types. One is to directly use inflation pressurization equipment and pressure measuring equipment for testing, and the other is to put the car lights into water for pressure testing. These two methods, on the one hand, need to clamp and fix the car lights, and the clamping method makes the car lights subject to greater pressure, and some tiny leaks at the joints are easily compressed. At this time, it is undoubtedly inaccurate to perform a pressure test. At the same time, using pressure measuring equipment in conjunction with pressurization equipment, even if there is a leak, it is not convenient to know where the leak is, which affects the subsequent repair. On the other hand, if the car lights are directly placed in water, a large amount of water will enter the inside of the car lights with leaks, which may seriously cause the car lights to be scrapped, wasting resources and inconvenient to perform convenient and stable air tightness tests on the car lights.

[0005] In view of the above problems, it is urgent to carry out innovative design based on the original airtightness test system. Summary of the invention

In the traditional technology, one part is tested by pressurizing and measuring pressure, and the other part is directly placing the lamp in water for testing. There are problems of high testing cost and easy damage to the lamp during the testing process. On the other hand, the present invention can conveniently test lamps of different specifications, with simple operation and high practicality, while reducing costs and improving economic benefits.

When the first gear ring 22 and the second gear ring 23 rotate, the elastic expansion and contraction of the track rod 27 allows the track rod 27 to always be in contact with the periphery of the lamp, and then the position of the nozzle 31 is synchronously adjusted with the adjustment component 33, so that the liquid sprayed by the nozzle 31 is evenly sprayed on the sealing part of the lamp. With the inflator and observation mirror 231, the airtightness of the lamp can be observed conveniently and accurately by observing the bubbles. ;

[0036] Working principle: When using the airtightness test system for intelligent manufacturing of automotive lamps, Figure 1-8 In the embodiment, the comparison lamp is first placed between the left first support plate 3 and the standard fixing head 12, and the lamp is located in the first gear ring 22, so that the lampshade is facing the standard fixing head 12, and the handle 201 is lifted upward, and the handle 201 is positioned and slid vertically in the base 1 through the positioning sleeve 202, so that the bevel teeth at the end of the handle 201 are engaged with the bevel teeth at the bottom of the first screw 8, and the handle 201 is rotated, and the handle 201 drives the first screw 8 to rotate, which can drive the first piston plate 9 to move in the oil chamber 7. The oil in the oil chamber 7 is squeezed into the standard inner support seat 10 through the pipeline, and the oil squeezes the standard fixing head 12, so that the standard fixing head 12 moves outward, and then the standard fixing head 12 contacts the headlight, and cooperates with the outer fixing head 5 to fix the headlight. At the same time, since the lampshade of most headlights is an arc-shaped structure, when the oil continues to enter the standard inner support seat 10, multiple standard fixing heads 12 are continuously squeezed by force, so that multiple standard fixing heads 12 can contact the arc surface of the headlight, thereby improving the clamping The stability of the standard fixing head 12 is ensured. At the same time, when the standard fixing head 12 moves, the first rack 181 can be driven to move. The first rack 181 drives the second rack 182 to move in the opposite direction through the first gear roller 183, and then drives the test fixing head 15 and the suction cup 16 to move outward through the second rack 182, and adjusts the position of the suction cup 16. Then, the headlight to be tested is placed opposite to the right side of the support seat 6. Since the initial position of the suction cup 16 is closer than the initial position of the standard fixing head 12, the suction cup 16 is only in contact with the headlight cover at this time, and then the suction cup 16 is evacuated by the vacuum pump 17, so that multiple suction cups 16 adsorb the headlight cover on the arc track, and the right side outer fixing head 5 is cooperated to fix the headlight to be tested. Then, the pipe on the air pump 2 is connected to the air inlet of the headlight to be tested, which is convenient for subsequent inflation, and changes the two-side extrusion fixation in the traditional equipment to avoid the situation where the minor leakage points are squeezed and sealed. After the test is completed, it is only necessary to take out the headlight to be tested, and there is no need to take out the left headlight;

[0037] Next, the handle 201 is slid downward so that the bevel gear at the end of the handle 201 meshes with the bevel gear at the end of the second screw 20. The handle 201 is rotated to drive the left and right second screws 20 to rotate, which can drive the left and right movable seats 21 to slide in opposite directions in the movable groove 19, thereby driving the first gear ring 22 and the second gear ring 23 to slide in opposite directions, so that the first gear ring 22 and the second gear ring 23 move to the test position of the comparison lamp and the lamp to be tested, and the transmission gear 24 is driven by the motor to rotate, and the transmission gear 2 4 drives the first gear ring 22 and the second gear ring 23 to rotate. When the first gear ring 22 rotates, the bottom roller of the track rod 27 contacts the outer side of the contrast lamp. Through the elastic expansion and contraction of the track rod 27, the end of the track rod 27 can always contact the contrast lamp detection position during the rotation process. The contraction of the track rod 27 squeezes the oil in the regulating oil chamber 3305, so that the oil in the regulating oil chamber 3305 passes through the left sealing ring 3304, the auxiliary oil pipe 3303 and the main oil pipe 3302. The oil delivery chamber 3306 on the left side of the adjustment seat 3301 is entered. The left oil delivery chamber 3306 drives the left adjustment rack 3308 to move through the second piston plate 3309. The left adjustment rack 3308 drives the right adjustment rack 3308 to move in the opposite direction through the second gear roller 3307, so that the oil in the right oil delivery chamber 3306 has space to enter. At this time, the mounting rod 30 is forced to move upward under the elastic tension of the fourth spring 29, driving the spray head 31 to move upward. This process can make the spray head 31 move upward. The head 31 moves synchronously with the track rod 27, so that the joint between the nozzle 31 and the lamp always maintains a constant position, so that the liquid sprayed by the nozzle 31 is evenly sprayed on the joint of the lamp. With the rotation of the first gear ring 22 and the second gear ring 23, the joint of the lamp is evenly sprayed with liquid. The joint is visually observed with the observation mirror 231. If bubbles are seen, it means that the air tightness of the lamp is poor. After the test is completed, the handle 201 is rotated in the reverse direction to remove the tested lamp and install a new lamp.
