Description

Technical Field

[0002] In the automotive industry, the importance of headlights is self-evident, as their performance directly affects vehicle safety and user experience. Headlights, serving as the primary illumination tool for nighttime driving and a warning device for various driving signals, encompass multiple types including headlights, taillights, and turn signals. The quality of the light distribution performance of automotive headlights has a significant impact on the safety of the vehicle and its occupants. Therefore, after headlight assembly, rigorous illumination testing must be conducted to ensure that the light type and position conform to the preset range.

[0003] Currently, traditional automotive headlight dimming processes generally rely on manual operation. For example, at the headlight dimming inspection station during vehicle assembly line testing at the OEM, specialized personnel are required to manually adjust the initial position of the low beam headlights to ensure that the main optical axis of the low beam headlights is in the set position. Due to manufacturing errors in the vehicle body and headlight assembly errors, the main optical axis of the low beam headlights is prone to shift. In this case, it is necessary to manually adjust the main optical axis of the low beam headlights according to the offset between the main optical axis of the low beam headlights on the light meter screen and the set value, first using an electric screwdriver for coarse adjustment, and then using a manual Phillips screwdriver for fine adjustment. This process is extremely tedious, requires a high level of skill from the dimming personnel, consumes a lot of manpower and time, and is labor-intensive, seriously affecting production efficiency.

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.

For example, "connection" can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium; it can be a connection within two components. For those skilled in the art, the specific meaning of the above terms in this utility model can be understood according to the specific circumstances.

[0028] This utility model provides, for example Figures 1 to 5 The illustrated automotive headlight dimming testing device includes:

[0029] The base 1 has a frame 2 connected to its top. A front door 3 is slidably connected to the front end of the frame 2, and a rear door 4 is slidably connected to the rear end. Both ends of the frame 2 are equipped with lifting cylinders 5, and the piston rods of the two sets of lifting cylinders 5 are respectively connected to the front door 3 and the rear door 4.

[0030] A movable slide table 6 is slidably connected to a slide rail provided inside the base 1. The movable slide table 6 is provided with two sets of dimming components for clamping and dimming the vehicle lights. The dimming components include a clamping platform 7 and a clamping cylinder 8. The clamping platform 7 is connected to the base 1 and the clamping cylinder 8 is provided on the clamping platform 7 for clamping the vehicle lights. Two sets of dimming motors 9 for dimming the vehicle lights are provided on one side of the clamping platform 7.

[0031] The dark box 10 has two sets, both of which are mounted on the frame 2, and is used to allow the left and right vehicle headlight beams to enter the dark box 10.

[0032] The piston rod of the clamping cylinder 8 is connected to a clamping plate 11. The clamping plate 11 cooperates with the fixing plate 12 on the clamping platform 7 to clamp the vehicle light. A screwdriver 13 is connected to the output shaft of the dimming motor 9.

[0033] The frame 2 is equipped with an X-axis servo lead screw linear module 14, and a mounting bracket is connected to the X-axis moving slide of the X-axis servo lead screw linear module 14. The mounting bracket is equipped with a Z-axis servo lead screw linear module 15, and the dark box 10 is connected to the Z-axis moving slide of the Z-axis servo lead screw linear module 15.

[0034] The bottom of the dark box 10 is equipped with a lens and a CCD camera is installed inside the dark box 10. The CCD camera can clearly capture key information such as the light intensity distribution, illumination angle, and cutoff line of the light beam, so as to realize high-precision imaging and data acquisition of the vehicle headlight beam.

[0035] The base 1 is provided with a Y-axis servo lead screw linear module 16, and one end of the movable slide 6 is connected to the Y-axis movable slide of the Y-axis servo lead screw linear module 16.

[0036] The frame 2 is equipped with a control panel 17, and the front end of the base 1 is equipped with several cooling fans 18. The cooling fans 18 use forced convection to quickly exhaust the hot air inside the base 1 and introduce external cold air, maintaining the internal temperature of the base 1 within a reasonable range, ensuring that each component operates within the rated operating temperature range, and avoiding performance degradation caused by overheating.

[0037] The base 1 is provided with several feet 19 and casters 20 at its bottom. The feet 19 can be used to fix the equipment and ensure the stability of the testing process, while the casters 20 facilitate the movement and position adjustment of the equipment, making it convenient to move the equipment between different production sites or workstations.

[0038] The movable slide table 6 is equipped with several detection sockets 21, and the front end of the base 1 is equipped with two sets of control switches 22 for controlling the lifting and lowering of the front door 3. When manual feeding is required, the lifting cylinder 5 set at the front door 3 can be controlled by the control switch 22 to drive the front door 3 to rise and open the front end of the frame 2, making it convenient for manual feeding. Thus, automated and manual feeding can be achieved through the front door 3 and the rear door 4.

[0039] When the vehicle headlight dimming detection equipment needs to detect the dimming of the headlights, the control panel 17 controls one of the lifting cylinders 5 to work. The piston rod of the lifting cylinder 5 pushes the rear door 4 upward. At this time, the Y-axis servo screw linear module 16 works, driving the moving slide 6 to move out of the frame 2. At this time, the clamped headlight can be placed in the designated area of ​​the clamping platform 7 on the moving slide 6 by an externally set robotic arm. The position sensor built into the clamping cylinder 8 monitors the status of the piston rod in real time. When the system issues a clamping command, the solenoid valve in the cylinder switches the air path, and the compressed air pushes the piston rod to extend, driving the clamping plate 11 to move smoothly along the preset guide rail towards the fixed plate 12, firmly clamping and fixing the headlight on the clamping platform 7. At the same time, the photoelectric sensor on the clamping platform 7 confirms the headlight's position information and feeds the signal back to the control system in the control panel 17. The control system restarts the Y-axis servo screw linear module 16 to work, moves the moving slide 6 into the frame 2, and lowers the opened rear door 4 through the lifting cylinder 5, closing the rear end of the frame 2.

[0040] The control system, based on its built-in dimming algorithm and combined with pre-recorded headlight model parameters and standard dimming data, calculates the required adjustment parameters according to the deviation between the current headlight state and the preset dimming standard. For example, if a deviation in the headlight's main optical axis angle is detected, the system will accurately calculate parameters such as the angle compensation value, rotation direction, and torque magnitude. Subsequently, the control system sends a control command to the dimming motor 9. The output shaft of the dimming motor 9 is securely connected to the screwdriver 13 via a coupling. Since headlights typically use a spiral adjustment screw, the rotation of the screwdriver 13 will cause the adjustment screw to move forward or backward along the axial direction. When the adjustment screw is screwed in, it will push the connected lamp body bracket or lens assembly, causing the headlight's illumination angle to deflect upward or in a certain direction. Conversely, when the adjustment screw is screwed out, under the action of the internal spring of the headlight, the headlight components move in the opposite direction, and the illumination angle changes accordingly. Thus, driven by the motor, the screwdriver 13 operates the headlight's adjustment screw with precise torque and speed, achieving automated and precise dimming of the headlight's angle and position.

[0041] After dimming is completed, the X-axis servo lead screw linear module 14 and the Z-axis servo lead screw linear module 15 in the frame 2 work together. Driven by the servo motor, the rotational motion is converted into linear motion through the lead screw nut pair, which drives the moving slide 6 to move smoothly along the X and Z axes. The X-axis servo lead screw linear module 14 can drive the mounting bracket to move along the X-axis, while the Z-axis servo lead screw linear module 15 realizes the precise lifting and lowering of the dark box 10 in the Z-axis direction through the Z-axis moving slide 6. The two work together to make the dark box 10 accurately aligned with the direction of the vehicle headlight beam, ensuring that the left and right vehicle headlight beams can accurately enter the dark box 10.

[0042] The aspherical lens at the bottom of the dark chamber 10 focuses the incoming light beam with high precision, eliminating aberrations and ensuring the beam is uniformly projected onto the photosensitive surface of the internal CCD camera. The CCD camera captures the beam image information and converts it into an electrical signal. After the analog signal is converted into a digital signal by the A / D conversion module, it is transmitted to the equipment's control system. The control system uses image recognition algorithms to extract and analyze key parameters such as the beam's intensity distribution, illumination angle, and cutoff line, and compares them with preset standard beam parameters in multiple dimensions to accurately determine whether the headlight's light distribution performance meets the requirements. If the test results show that the headlight's light distribution performance meets the preset standard, the control system controls the audible and visual alarm to issue a qualified prompt signal, and simultaneously displays a qualified mark on the control panel 17 display screen on the surface of the frame 2. If the test results do not meet the requirements, the dimming motor 9 is controlled again to perform targeted secondary or multiple dimming operations. After each dimming, the equipment repeats the beam detection process until the headlight's light distribution performance reaches the preset standard. Throughout the entire testing process, operators can view the testing progress, detailed test data, and dimming process records in real time through the control panel 17, facilitating comprehensive monitoring and management of the equipment.

[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.
