Description

Technical Field

[0001] This utility model relates to the field of vehicle lamp assembly technology, and in particular to a tooling for assembling vehicle lamp lens modules. Background Technology

[0002] The headlight lens module is a key component of the vehicle lighting system. It mainly consists of lenses and other related parts, used to focus and adjust light to improve lighting effect and driving safety. Headlight lens modules can be divided into single-beam lenses and bi-beam lenses according to the type of lens. Single-beam lenses are mainly used for low beam or high beam lighting, while bi-beam lenses can switch between low beam and high beam through mechanisms such as solenoid valves. A suitable lens can effectively reduce glare to other road users and reduce the risk of traffic accidents.

[0003] A search revealed that Chinese patent CN213004881U discloses an assembly fixture for assembling automotive headlight lens modules. The existing method for assembling automotive headlight lenses primarily involves manual gluing. This method is not only labor-intensive, but also prone to causing lenses to slip and break after worker fatigue. Furthermore, it cannot accurately assemble lenses of different diameters, and the glue cannot dry quickly after application, severely reducing production efficiency. Therefore, this fixture can clamp and fix lenses of different sizes, facilitate glue application and assembly, and automatically compress and dry the lenses after gluing.

[0004] The aforementioned assembly fixtures facilitate lens clamping and drying after adhesive application. However, after clamping the lens with the fixtures, the lens is usually directly coated with adhesive for assembly, which makes it difficult to clean the lens surface. Dust in the air can easily adhere to the lens surface during the clamping process, resulting in dust and dirt on the lens. If contaminants are not effectively removed, they may affect the fit between the lens and other components of the module during assembly, leading to abnormal light scattering, refraction, or reflection, thereby reducing the overall quality of the product.

[0032] 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.

[0033] As attached Figure 1-7 As shown, one embodiment of this utility model is provided: a tooling for assembling a vehicle headlight lens module, including a processing table 1, a mounting bracket 2 fixedly connected to the upper surface of the processing table 1, a hydraulic cylinder 3 fixedly installed in the middle of the mounting bracket 2, a pressure plate 4 fixedly connected to the output end of the hydraulic cylinder 3, and a cleaning component provided on the upper surface of the processing table 1.

[0034] The cleaning assembly includes two fixed plates 5, which are fixedly connected to the upper surface of the processing table 1. The two fixed plates 5 are located on one side of the mounting frame 2. A first stepper motor 6 is fixedly installed on one side of one of the fixed plates 5. A lead screw 7 is fixedly connected to the output end of the first stepper motor 6. The lead screw 7 is rotatably connected between the two fixed plates 5. A fixing rod 8 is fixedly connected between the two fixed plates 5. The lead screw 7 facilitates the movement of the connecting block 9, and the fixing rod 8 limits the movement of the connecting block 9.

[0035] As attached Figure 1 As shown, the lead screw 7 is positioned above the fixed rod 8. The lead screw 7 is threadedly connected to a connecting block 9, which is slidably connected to the outside of the fixed rod 8. A stud 11 is rotatably connected to one side of the connecting block 9, and a throttle 10 is fixedly connected to one end of the stud 11. The stud 11 allows for adjustment of the height position of the mounting rod 14 by rotating the throttle 10.

[0036] As attached Figure 3 As shown, a groove 12 is provided on one side of the connecting block 9 to facilitate the sliding of the slider 13, thereby limiting the mounting rod 14.

[0037] As attached Figure 4 As shown, a slider 13 is slidably connected inside the slide groove 12. A mounting rod 14 is fixedly connected to one side of the slider 13. A mounting sleeve 15 is slidably connected to the outside of the mounting rod 14. A threaded hole 16 is opened on the upper surface of the mounting sleeve 15. A bolt 17 is threaded inside the threaded hole 16. Multiple microfiber thick cloth strips 18 are provided on the lower surface of the mounting sleeve 15. The mounting rod 14 facilitates the installation of the mounting sleeve 15, while the threaded hole 16 facilitates the installation of the bolt 17, thereby fixing the mounting sleeve 15. The microfiber thick cloth strips 18 help to clean dust from the lens surface.

[0038] As attached Figure 2 As shown, a clamping assembly is provided on the lower surface of the processing table 1. The clamping assembly includes a gear 19, which is rotatably connected to the lower surface of the processing table 1. Two sliding grooves 20 are provided on the lower surface of the processing table 1, and two connecting grooves 25 are provided inside the processing table 1. When the gear 19 rotates, it facilitates the simultaneous movement of the two racks 22. The connecting grooves 25 are used for the movement of the connecting frame 23.

[0039] As attached Figure 7 As shown, a sliding block 21 is slidably connected inside the sliding groove 20. A rack 22 is fixedly connected to the lower surface of the sliding block 21. The two racks 22 are meshed with the gear 19. A connecting frame 23 is fixedly connected to one side of the rack 22. The connecting frame 23 is slidably connected inside the connecting groove 25. A clamping block 24 is fixedly connected to one side of the connecting frame 23. The connecting frame 23 is used to connect the clamping block 24 and the rack 22, so that the rack 22 moves and drives the clamping block 24 to move.

[0040] As attached Figure 2 As shown, a second stepper motor 26 is fixedly installed on the lower surface of the processing table 1. A screw 27 is fixedly connected to the output end of the second stepper motor 26. A moving block 28 is connected to the external thread of the screw 27. The moving block 28 is fixedly connected to the lower surface of one of the connecting frames 23. The screw 27 can easily drive the moving block 28 to move, thereby driving one of the connecting frames 23 to move through the moving block 28.

[0041] Working principle: When clamping is required before lens assembly, the lens is placed between two clamping blocks 24. Then, the second stepper motor 26 is turned on, and its output end drives the screw 27 to rotate, causing the screw 27 to move the moving block 28. When the moving block 28 moves, it drives one of the connecting frames 23 to move, causing the connecting frame 23 to drive the rack 22 to move. At this time, the sliding block 21 slides inside the sliding groove 20. When the rack 22 moves, it meshes with the gear 19, causing the gear 19 to rotate. The gear 19 meshes with both racks 22, thereby driving the other rack 22 to move. The other rack 22 drives the other connecting frame 23 to slide inside the connecting groove 25, so that the two connecting frames 23 drive the clamping blocks 24 to move closer to each other, clamping and fixing the lens.

[0042] When cleaning the lens surface is required, first adjust the height of the microfiber thick cloth strip 18 according to the height of the lens. Turn the handle 10 to drive the stud 11 to rotate. The stud 11 drives the mounting rod 14 to move downward. At this time, the slider 13 slides inside the slide groove 12. When the microfiber thick cloth strip 18 is indirectly moved to the height of the lens surface, the first step motor 6 is turned on. When the lead screw 7 is rotated, the lead screw 7 drives the connecting block 9 to move. At this time, the connecting block 9 slides outside the fixed rod 8, thereby driving the mounting rod 14 to move through the connection of the slider 13. This, in turn, drives the mounting sleeve 15 and multiple microfiber thick cloth strips 18 to move laterally. When the microfiber thick cloth strip 18 moves to the lens surface, it is in close contact with the lens at an appropriate height. Thus, the dust and lint on the lens surface are brushed away by the microfiber thick cloth strip 18, improving the cleanliness of the lens surface.

[0043] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
