[0029] As shown in Figure 1 The embodiment of the present application provides a vehicle lamp light detection device, which comprises a light shape detection mechanism 10, a lifting mechanism 20, a vehicle lamp supporting mechanism 30 and a transportation mechanism 40. The light shape detection mechanism 10 is arranged on the lifting mechanism 20, the lifting mechanism 20 can drive the light shape detection mechanism 10 to move up and down, the vehicle lamp supporting mechanism 30 is arranged on the transportation mechanism 40, and the transportation mechanism 40 can drive the vehicle lamp supporting mechanism 30 to move to the position directly below the light shape detection mechanism 10.
[0030] In work, the vehicle lamp to be detected is placed on the vehicle lamp supporting mechanism 30, and the vehicle lamp supporting mechanism 30 and the vehicle lamp are transported to the position directly below the light shape detection mechanism 10 by the transportation mechanism 40, so that the vehicle lamp does not need to be manually carried to the position directly below the light shape detection mechanism 10, thereby reducing the labor intensity of workers and improving the detection efficiency. The distance between the vehicle lamp and the light shape detection mechanism 10 required for light shape detection of different types of vehicle lamps is often different, the light shape detection mechanism 10 is driven to move up and down by the lifting mechanism 20, so as to adjust the distance between the light shape detection mechanism 10 and the vehicle lamp, thereby meeting the light shape detection requirements of different types of vehicle lamps. In addition, compared with manually carrying the vehicle lamp to the position directly below the light shape detection mechanism 10, the vehicle lamp supporting mechanism 30 and the vehicle lamp are transported to the position directly below the light shape detection mechanism 10 by the transportation mechanism 40, so as to improve the positioning accuracy of the vehicle lamp supporting mechanism 30 and the vehicle lamp, thereby improving the accuracy of light shape detection. When the detection is completed, the vehicle lamp after detection can be sent out of the area directly below the light shape detection mechanism 10 by the transportation mechanism 40, without manual carrying of the vehicle lamp.
[0031] In one embodiment, as Figure 3As shown, the light form detection mechanism 10 comprises a dark box 11, an imaging lens 12, a projection plate 13 and a detection camera 14. The dark box 11 is driven by a lifting mechanism 20. The bottom of the dark box 11 is provided with a first opening 111. The imaging lens 12 is arranged at the bottom of the dark box 11 and covers the first opening 111. The projection plate 13 is arranged at the top of the dark box 11. The detection camera 14 is arranged in the dark box 11 and is used to detect the light form of the light projected on the projection plate 13 through the imaging lens 12. In operation, first, the vehicle lamp supporting mechanism 30 on which the vehicle lamp is placed is transported to the position directly below the dark box 11 by the transportation mechanism 40. Then, the vehicle lamp is turned on. The light emitted by the vehicle lamp enters the dark box 11 through the imaging lens 12 and is projected on the projection plate 13, thereby presenting the light form of the light. The detection camera 14 captures the light form on the projection plate 13. Then, whether the light form is qualified can be determined by a visual algorithm. By introducing the light of the vehicle lamp into the dark box 11, a light-shielded environment for light form detection can be provided, thereby improving the accuracy of light form detection and avoiding the interference of external light and external sundries in the light form detection. When it is necessary to adjust the distance between the light form detection mechanism 10 and the vehicle lamp, the dark box 11 is moved up and down by the lifting mechanism 20. The dark box 11 drives the imaging lens 12, the projection plate 13 and the detection camera 14 to move up and down together.
[0032] In one embodiment, as shown in Figure 3 The inner wall of the dark box 11 is provided with a lens fixing profile 15 corresponding to the position of the first opening 111. The imaging lens 12 is arranged at the top of the lens fixing profile 15. The shape of the imaging lens 12 can be square. The lens fixing profile 15 is in the shape of a square frame and can stably support the four peripheral edges of the imaging lens 12.
[0033] In one embodiment, as shown in Figure 3 The top of the dark box 11 is provided with a second opening 112. The projection plate 13 covers the second opening 112. The projection plate 13 plays a role in presenting the light form and covers the second opening 112 as a part of the housing of the dark box 11, thereby cooperating with the dark box 11 to create a light-shielded environment. Compared with the case that the top of the dark box 11 is closed and the projection plate 13 is arranged inside the dark box 11, such an arrangement can simplify the structure of the light form detection mechanism 10, save materials and reduce production cost.
[0034] In one embodiment, as shown in Figure 3 The inner wall of the dark box 11 is provided with a projection plate supporting rib 16 corresponding to the position of the second opening 112. The projection plate 13 is arranged at the top of the projection plate supporting rib 16. Specifically, the projection plate 13 can be fixed on the projection plate supporting rib 16 by screws.
[0035] In one embodiment, the imaging lens 12 is a Fresnel lens. A Fresnel lens, also known as a threaded lens, functions to focus light, converging the light emitted from the vehicle headlights onto the projection panel 13 to simulate a light effect from 25 meters away. Compared to a typical convex lens, a Fresnel lens has stronger light-gathering capabilities and is also thinner and lighter.
[0036] In one embodiment, combined Figure 3 and Figure 4 As shown, the vehicle headlight detection device also includes an adjustment assembly 17 for mounting the detection camera 14. The adjustment assembly 17 includes a movable adjustment plate 171 and a threaded fastener (not shown). The movable adjustment plate 171 has a slotted hole 1711, and the peripheral side of the dark box 11 has a threaded hole (not shown). The threaded fastener passes through the slotted hole 1711 and is threaded into the threaded hole. When installing the movable adjustment plate 171, the slotted hole 1711 of the movable adjustment plate 171 is aligned with the threaded hole of the dark box 11, and then the threaded fastener is used to pass through the slotted hole 1711 and be threaded into the threaded hole, thereby fixing the movable adjustment plate 171 to the inner wall of the dark box 11. When it is necessary to adjust the position of the detection camera 14 mounted on the movable adjustment plate 171, loosen the threaded fasteners. The movable adjustment plate 171 can then be moved along the length of the strip hole 1711, thereby adjusting the position of the detection camera 14. After adjustment, retighten the threaded fasteners to fix the movable adjustment plate 171 to the inner wall of the dark box 11. The adjustable position of the detection camera 14 helps improve detection accuracy and meets the light pattern detection requirements of different types of vehicle lights. Specifically, the strip hole 1711 extends vertically, allowing for vertical adjustment of the detection camera 14's position, thereby adjusting the distance between the detection camera 14 and the projection plate 13.
[0037] In one embodiment, such as Figure 4 As shown, the adjustment assembly 17 also includes a rotating adjustment member 172, which is hinged to the movable adjustment plate 171. The detection camera 14 is mounted on the rotating adjustment member 172. When it is necessary to adjust the position of the detection camera 14 mounted on the adjustment assembly 17, the threaded fastener is loosened, and then the movable adjustment plate 171 can be moved along the length direction of the slot 1711. The movable adjustment plate 171 drives the rotating adjustment member 172 and the detection camera 14 to move together, thereby adjusting the position of the detection camera 14. After adjustment, the threaded fastener is tightened to fix the movable adjustment plate 171 to the inner wall of the dark box 11. When it is necessary to adjust the angle of the detection camera 14, the rotating adjustment member 172 is rotated relative to the movable adjustment plate 171. The rotating adjustment member 172 drives the detection camera 14 to rotate, thereby adjusting the angle of the detection camera 14. The adjustable angle of the detection camera 14 is beneficial to improving the accuracy of detection and meeting the light pattern detection requirements of different types of vehicle lights.

Specifically, the pivot shaft 1733 is arranged horizontally, thereby being able to adjust the pitch angle of the camera.
[0039] In one embodiment, as shown in Figure 1 and Figure 2 The lifting mechanism 20 comprises a rotating column 21, a linear moving member 22 and a driver 23, the rotating column 21 extending along the vertical direction, the linear moving member 22 being threadedly sleeved on the rotating column 21 and being fixed to the light shape detection mechanism 10, the moving end of the driver 23 being connected to the rotating column 21, the driver 23 being able to drive the rotating column 21 to rotate, thereby driving the linear moving member 22 to move up and down. When it is needed to adjust the distance between the light shape detection mechanism 10 and the vehicle lamp, the driver 23 is started, the driver 23 drives the rotating column 21 to rotate around its axis, thereby driving the linear moving member 22 to move up and down along the rotating column 21, the linear moving member 22 further driving the light shape detection mechanism 10 to move up and down, thereby realizing the adjustment of the distance between the light shape detection mechanism 10 and the vehicle lamp. Specifically, the linear moving member 22 is fixed to the outer wall of the dark box 11 of the light shape detection mechanism 10. Specifically, the driver 23 can be a servo motor, the rotating column 21 can be a ball screw, and the linear moving member 22 can be a nut.

Through the sliding fit of the first sliding block 26 and the first sliding rail 25, the light form detection mechanism 10 can be stably moved along the vertical direction, and the position deviation of the light form detection mechanism 10 in the horizontal direction is avoided, so that the accuracy of light form detection is improved. Specifically, the first sliding block 26 is fixedly connected to the outer wall of the dark box 11 of the light form detection mechanism 10. Specifically, the number of the first sliding rail 25 is two, the two first sliding rails 25 are located on opposite sides of the rotating column 21 respectively, and the number of the first sliding block 26 corresponds to two, the two first sliding blocks 26 are in sliding fit with the two first sliding rails 25 respectively, which can improve the moving stability of the light form detection mechanism 10.

The linear module 41 has the advantages of high positioning accuracy, can realize accurate positioning of the vehicle lamp supporting mechanism 30, and improves the detection accuracy. The linear module 41 also has the advantages of simple structure, stable movement and low noise. By horizontally arranging the linear module 41, the vehicle lamp supporting mechanism 30 and the vehicle lamp can be stably transported to the position directly below the light form detection mechanism 10 in the horizontal direction. Specifically, the linear module 41 can be a synchronous belt driven linear module 41, or a screw driven linear module 41.
