In addition, "first", "second", "third", and "fourth" are only used for descriptive purposes and cannot be understood as indicating or implying relative importance.

[0035] In the description of the present invention, it is also necessary to explain that, unless otherwise clearly specified and limited, the terms "set", "install", "connect", and "connect" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection, it can be a mechanical connection, it can be an electrical connection, it can be a direct connection, it can be connected through an intermediate medium, and it can be the internal communication of two components. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0036] like Figures 1 to 6 As shown, the optical measuring device for a welcome light of the present invention is used to measure a welcome light 10 to detect the lighting effect of the welcome light 10; the optical measuring device for a welcome light specifically comprises a frame 20, a measuring lens 30 installed at the upper inner end of the frame 20, a manipulator 40 disposed at one side of the frame 20, and a plurality of placement brackets 50 disposed at one side of the frame 20. For ease of use, the placement brackets 50 and the manipulators 40 are placed at the same side of the frame 20. The placement brackets 50 are used to place the welcome light 10 to be measured.

[0037] When testing the lighting effect of the welcome lamp 10, the manipulator 40 clamps the welcome lamp 10 placed on the bracket 50 and moves it into the rack 20. The manipulator 40 swings the welcome lamp 10 to simulate the lighting angle when installed on a real vehicle, and directs the light emitted by the welcome lamp 10 vertically or obliquely toward the bottom inner side of the rack 20 for display. The measuring lens 30 shoots the light emitted by the welcome lamp 10 downward for optical measurement, thereby realizing the measurement of the lighting effect of the welcome lamp 10.

[0038] A further improvement to the above scheme is that a reflective plate 21 is fixedly provided at the bottom inner side of the frame 20, and the welcome light 10 emits light toward the reflective plate 21. The reflective plate 21 is used to simulate the ground or floor in actual applications, thereby improving the measurement accuracy of the lighting effect of the welcome light 10.

[0039] A further improvement to the above solution is that a lifting assembly 31 is connected to one side of the measuring lens 30, and the lifting assembly 31 drives the measuring lens 30 to swing and lift. The measuring lens 30 is lifted and lowered for better focusing and better shooting.

[0040] In addition, a screw rod 60 is fixedly provided at the inner upper end of the frame 20, a nut (not shown in the figure) is sleeved on the outer side of the screw rod 60, and a driving motor 61 is provided at one end of the screw rod 60; a connecting plate 32 is provided at the upper end of the lifting assembly 31, and the upper end of the connecting plate 32 is fixedly connected to the nut, and the driving motor 61 drives the nut to move back and forth along the screw rod 60, thereby driving the lifting assembly 31 and the measuring lens 30 to move back and forth along the screw rod 60 to adjust the position. Further, a slide rail 62 is provided on the side of the screw rod 60 and arranged parallel to it, and a slider (not shown in the figure) is fixedly provided on the upper end of the connecting plate 32, and the slider is slidably connected to the slide rail 62 to ensure that the lifting assembly 31 and the measuring lens 30 can ensure linear movement.

[0041] A further improvement to the above scheme is that a clamping arm 41 is provided at one end of the manipulator 40, and a conductive member 42 is provided on the inner side of the clamping arm 41. The clamping arm 41 clamps the welcome light 10 to facilitate the manipulator 40 to move the welcome light 10 into the frame 20. During this process, the conductive member 42 contacts the welcome light 10 and is energized, causing the welcome light 10 to emit light.

[0042] A further improvement to the above scheme is that an electric control box 70 and a display are provided on the side of the frame 20. The electric control box 70 is electrically connected to the manipulator 40 and the measuring lens 30, and controls the motion trajectory of the manipulator 40 and the shooting of the measuring lens 30 by outputting relevant control instructions. The display is electrically connected to the manipulator 40 and the measuring lens 30 to display their working conditions.

[0043] A further improvement to the above scheme is that a support platform 80 is provided on the side of the frame 20, a turntable 81 is provided on the support platform 80, a drive-connected electric-controlled rotating platform 82 is provided at the lower end of the turntable 81, a U-shaped support frame 83 is provided at the lower end of the support platform 80, the electric-controlled rotating platform 82 is placed on the support frame 83, the placement bracket 50 is fixed on the turntable 81, and the electric-controlled rotating platform 82 drives the turntable 81 to rotate to move the placement bracket 50 to a specified position, so that the manipulator 40 can clamp the welcome light 10 on the placement bracket 50, increase the rotation speed during the test, and increase the test speed. Further, multiple placement brackets 50 are distributed in a circular array on the upper end surface of the turntable 81, and sufficient spacing is ensured between adjacent placement brackets 50 to avoid interference that affects the manipulator 40 clamping the welcome light 10. The placement bracket 50 includes a support plate 51 and a support column 52 fixed to the lower end of the support plate 51. The welcome lamp 10 is placed on the upper end surface of the support plate 51. The lower end of the support column 52 is fixedly connected to the turntable 81. The support column 52 props up the support plate 51 to a certain height to facilitate the robot 40 to clamp it.

[0044] A further improvement to the above solution is that the frame 20 includes a plurality of aluminum profiles 22 connected end to end for easy installation, and casters 23 are provided at the lower end of the frame 20 for easy movement.

[0045] The working principle of the welcome light optical measurement device involved in the present invention is as follows:

[0046] S1. By manual or mechanical feeding, the unfinished test welcome light 10 is placed on the bracket 50;

[0047] S2. The manipulator 40 grabs the welcome light 10, the welcome light 10 moves to the inside of the rack 20, the conductive member 42 is energized for the welcome light 10, the welcome light 10 emits light and projects an image onto the reflector 21;

[0048] S3. The measuring lens 30 is moved to the top of the projected image by the screw 60, and the swing arm is adjusted to drive the measuring lens 30 to adjust the angle and align it with the projected image;

[0049] S4. The measuring lens 30 captures the projected image and transmits it to the information processor. The optical parameters of the projected image are analyzed by the comparison software to complete the optical measurement and thus realize the test of the lighting effect of the welcome lamp 10.

[0050] Compared with the prior art, the optical measuring device for a welcome light of the present invention is used to measure the lighting performance of a welcome light 10, simulate the lighting scene of the welcome light 10, and improve the accuracy of optical measurement. Specifically, a frame 20 is provided, and a measuring lens 30 is provided at the inner upper end of the frame 20, and a manipulator 40 is provided on the side of the frame 20. The manipulator 40 clamps the welcome light 10 and energizes the welcome light 10 through a conductive member 42. The welcome light 10 emits light and hits the bottom of the measuring lens 30, and the measuring lens takes a picture to test the lighting performance of the welcome light 10. The manipulator 40 can simulate the lighting effects of the welcome light 10 at various angles, and measuring optical parameters through the measuring lens 30 helps to improve the accuracy of the lighting performance test of the welcome light 10. In addition, a reflector 21 is provided at the bottom of the frame 20 to better ensure the lighting effect of the welcome light 10.
