The appearance of this phrase in various places in the specification does not necessarily refer to the same embodiment, nor is it a mutually exclusive, independent, or alternative embodiment to other embodiments. It will be explicitly and implicitly understood by those skilled in the art that the embodiments described in this invention can be combined with other embodiments.
[0027] To enable those skilled in the art to better understand the present invention, the technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings.
[0028] like Figure 1-8 As shown, a vehicle-mounted head-up display (HUD) testing device includes a controller 100, a first testing device 200, and a second testing device 300. The first and second testing devices 200 are electrically connected to the controller 100. The first testing device 200 is used to perform stray light testing on the HUD product, and the second testing device 300 is used to perform high-temperature resistance and strong light resistance testing on the HUD product. In actual testing, the first and second testing devices 200 can work simultaneously without standby, thus improving testing efficiency; and the testing order of the first and second testing devices 200 is not important.
[0029] like Figure 2As shown, the first testing device 200 includes a windshield fixing device 1, an arched light source assembly 2, a light source driving device 3, a material handling robot 4, and a testing robot 5, all electrically connected to the controller 100. The windshield fixing device 1 is used to install the windshield and can drive the windshield to rotate and swing. Because the tilt angle of windshields varies among different vehicle models, the windshield fixing device 1 drives the windshield to rotate and swing, thereby changing its tilt angle and simulating the windshields of different vehicle models. The arched light source assembly 2 is fitted around the windshield fixing device 1 and is used to emit light onto the vehicle windshield of the windshield fixing device 1. The light source driving device 3 is connected to the arched light source assembly 2 and drives it to rotate and swing. By driving the arched light source assembly 2 to rotate and swing, the angle of the light irradiated onto the windshield by the arched light source assembly 2 changes, thus forming stray light. The end effector of the pick-and-place robot 4 is equipped with a first product gripper 6 for mounting the product to be tested. The product to be tested on the first product gripper 6 can be electrically connected to the controller 100. The pick-and-place robot 4 can drive the first product gripper 6 to move, so that the product to be tested on the first product gripper 6 can project an image onto the windshield on the windshield fixing device 1. The end effector of the testing robot 5 is equipped with a binocular camera 7. The testing robot 5 can drive the binocular camera 7 to move, so that the binocular camera 7 can capture the projected image on the windshield.
[0030] Before testing, the windshield is installed onto the windshield fixing device 1, and the product to be tested is installed onto the first product fixture 6. The product to be tested is electrically connected to the controller 100 via a wiring harness. Then, the loading and unloading robot 4 drives the first product fixture 6 to the projection position on the windshield, and then controls the arched light source assembly 2 and the product to be tested to work. The arched light source assembly 2 illuminates the windshield, and the product to be tested projects a projected image onto the windshield. At the same time, the light source driving device 3 drives the arched light source assembly 2 to rotate and swing, simulating light illumination from different angles. The testing robot 5 drives the binocular camera 7 to move, enabling the binocular camera 7 to capture the projected image on the windshield. The binocular camera 7 feeds back the captured image to the controller 100 in real time. The controller 100 compares the images to determine whether the projected image is normal, thereby analyzing the impact of stray light on the product to be tested and fulfilling the testing requirements. This automotive HUD testing equipment can complete the stray light test of the product to be tested without installing the HUD in the vehicle, reducing the testing time cycle and testing cost, and improving the testing efficiency of HUD products.
[0031] like Figure 3As shown, the second testing device 300 includes a baking oven 8 and a solar simulator 9, both electrically connected to the controller 100. The baking oven 8 contains a second product fixture 10, which is used to mount the product to be tested. The product to be tested on the second product fixture 10 can be electrically connected to the controller 100, allowing the controller 100 to control the operation of the product on the second product fixture 10 and acquire various parameters of the product during operation, including but not limited to voltage and current signals. The upper surface of the baking oven 8 is provided with a transparent contoured glass 11, which is aligned with the second product fixture 10. The contoured glass 11 can capture the area of the HUD projection position of a car after installation, thus enabling the product to be tested to simulate vehicle installation and improve testing accuracy. The light outlet of the solar simulator 9 is located directly above the contoured glass 11. The solar simulator 9 and the baking oven 8 are electrically connected to the controller 100. The light emitted by the solar simulator 9 can pass through the contoured glass 11 and illuminate the product to be tested on the second product fixture 10. The solar simulator 9 is used to emit simulated sunlight, thereby enabling the testing of the product's resistance to strong light indoors. Any existing solar simulator 9 can be used, and its specific structure is not limited in this invention.
[0032] In the specific testing process, the product under test is installed on the second product fixture 10 and electrically connected to the controller 100 via a wiring harness. The controller 100 then controls the operation of the baking oven 8 and the solar simulator 9. The baking oven 8 heats the product under test on the second product fixture 10, and the light emitted by the solar simulator 9 passes through the contoured glass 11 and shines onto the product under test. The controller 100 can then control the operation of the product under test. Because the product under test is electrically connected to the controller 100, the controller 100 can obtain various parameter information such as the voltage and current of the product under test, indicating whether it has started working or is operating. This allows the controller to determine whether the product under test is working and whether the parameters during operation are normal, thus completing the testing process for the product's high-temperature resistance and strong light resistance. This automotive HUD testing equipment can simultaneously test the high-temperature resistance and strong light resistance of the product under test without the need for transportation or multiple product clamping, improving testing efficiency.
[0033] The controller 100 can be an existing control device, and the controller 100 has a preset control program integrated in it, such as a PLC control system, etc. This utility model does not limit this.
[0034] like Figure 4As shown, the light source driving device 3 includes a first fixed base 31, on which a drive motor 32 is mounted. A hollow rotating platform 33 is mounted on the output end of the drive motor 32, and the output end of the hollow rotating platform 33 is connected to the arched light source assembly 2. In specific testing, the drive motor 32 drives the hollow rotating platform 33 to work, which in turn drives the arched light source assembly 2 to rotate and swing, thereby simulating the needs of light irradiation at different angles.
[0035] In this embodiment, there are two light source driving devices 3, and the two light source driving devices 3 are symmetrically distributed on both sides of the arched light source assembly 2. Each light source driving device 3 is connected to one end of the arched light source assembly 2.
[0036] like Figure 4-5 As shown, the arched light source assembly 2 includes an arched frame 201, with both ends of the arched frame 201 fixedly connected to the output ends of the corresponding hollow rotating platform 33. An LED bead 202 and an arched light guide 203 are mounted on the arched frame 201, with the arched light guide 203 surrounding the LED bead 202. During operation, the light emitted by the LED bead 202 illuminates the arched light guide 203 and diffuses outward through it, resulting in uniform light emission from the entire arched light source assembly 2 to meet testing requirements. The arched light guide 203 can be made of semi-transparent acrylic material.
[0037] To ensure that the arched light source assembly 2 can rotate and swing smoothly, counterweights 204 are installed at both ends of the arched frame 201. By installing counterweights 204, the weight on both sides of the arched frame 201 is relatively balanced, ensuring that the drive motor 32 can swing the arched light source assembly 2 smoothly when it rotates and swings, thus improving the stability of the transmission.
[0038] like Figure 6 As shown, the windshield fixing device 1 includes a second fixing base 101, on which a windshield fixing frame 102 and an angle adjustment component are mounted. The windshield fixing frame 102 has multiple windshield clamps 103 for holding the windshield. One end of the windshield fixing frame 102 is hinged to the second fixing base 101. The output end of the angle adjustment component is connected to the windshield fixing frame 102, and the angle adjustment component drives the windshield fixing frame 102 to rotate and swing on the second fixing base 101. During testing, the windshield is installed onto the windshield clamps 103 on the windshield fixing frame 102, and the windshield is fixed in place by the multiple clamps 103 before testing. In actual testing, the angle adjustment component can drive the windshield fixing frame 102 to rotate and swing, thereby changing the tilt angle of the windshield to meet the testing requirements of different vehicle models and improve the versatility of the equipment.
[0039] Specifically, the angle adjustment assembly includes an adjustment motor 104 and an adjustment screw 105. The adjustment motor 104 is fixedly mounted on the second fixed base 101. One end of the adjustment screw 105 is hinged to the windshield mounting bracket 102. A worm gear assembly 106 is mounted on the second fixed base 101. The output end of the adjustment motor 104 is connected to the worm gear assembly 106, and the adjustment screw 105 is connected to the output end of the worm gear assembly 106. The adjustment motor 104 can drive the adjustment screw 105 to slide on the second fixed base 101 through the worm gear assembly 106. When it is necessary to adjust the tilt angle of the windshield, the adjustment motor 104 can drive the worm gear assembly 106 to move, thereby causing the adjustment screw 105 to slide on the second fixed base 101. The sliding of the adjustment screw 105 can push or pull the windshield mounting bracket 102 to rotate and swing along the hinge end, thereby achieving the purpose of adjusting the tilt angle of the windshield.
[0040] In this embodiment, there are two angle adjustment components, and the two angle adjustment components are symmetrically distributed along the center line of the windshield fixing frame 102. The two angle adjustment components allow the windshield fixing frame 102 to be subjected to force from both sides simultaneously, improving the stability of the adjustment.
[0041] To enhance operational safety, the first testing device 200 also includes a protective frame 12. The protective frame 12 is fitted around the material handling robot 4, the testing robot 5, and the windshield fixing device 1, and a protective net 13 is provided on the protective frame 12. By setting up the protective frame 12 and the protective net 13, personnel are prevented from entering the equipment testing area during the testing process, thereby improving the safety of the test.
[0042] To facilitate the loading and unloading of products by the robotic arm 4, a loading and unloading port 14 is provided on the protective frame 12. The robotic arm 4 can drive the first product clamp 6 to move back and forth between the windshield fixing device 1 and the loading and unloading port 14. When it is necessary to load material, the robotic arm 4 can drive the first product clamp 6 to move to the loading and unloading port 14 so that the operator can perform loading and unloading operations on the first product clamp 6. During testing, the robotic arm 4 can move the first product clamp 6 with the product to be tested to the corresponding position on the windshield fixing device 1. The image of the product on the first product clamp 6 is projected onto the windshield on the windshield fixing device 1 to meet the testing requirements.
[0043] like Figure 3 As shown, the baking oven 8 is equipped with an opening and closing door 15. One end of the opening and closing door 15 is hinged to the baking oven 8, and the other end is detachably connected to the baking oven 8. Opening the opening and closing door 15 facilitates the loading and unloading of products on the second product fixture 10; closing the opening and closing door 15 makes the baking oven 8 form a closed box, which facilitates the heating of the products to be tested to meet the testing requirements.
[0044] The baking oven 8 is equipped with a lifting and adjusting mechanism. The second product clamp 10 is connected to the output end of the lifting and adjusting mechanism. The lifting and adjusting mechanism is used to drive the second product clamp 10 to move up and down within the baking oven 8, thereby aligning the product to be tested on the second product clamp 10 with the contoured glass 11 or the opening and closing door 15. When the second product clamp 10 is aligned with the contoured glass 11, the light emitted by the solar simulator 9 can illuminate the product to be tested on the second product clamp 10. When the second product clamp 10 is aligned with the opening and closing door 15, it is convenient to open the opening and closing door 15 to load and unload the product to be tested on the second product clamp 10. By setting up a lifting and adjusting mechanism, it is convenient to load and unload the product to be tested on the second product clamp 10, thus improving the convenience of testing.
[0045] like Figure 8 As shown, the lifting and adjusting assembly includes a third fixed base 16, an adjusting handwheel 17, and a reducer 18. The third fixed base 16 is fixedly installed inside the baking oven 8 with screws. The reducer 18 is fixedly installed on the third fixed base 16. The adjusting handwheel 17 is connected to the input end of the reducer 18. A lifting screw 19 is installed on the output end of the reducer 18. The lifting screw 19 and the adjusting handwheel 17 are rotatably limited to the third fixed base 16. A lifting slider 20 is sleeved on the lifting screw 19, and the lifting slider 20 is slidably connected to the lifting screw 19. The second product fixture 10 is fixedly installed on the lifting slider 20. When lifting and adjusting is required, the reducer 18 is driven to work by rotating the adjusting handwheel 17. The reducer 18 drives the lifting screw 19 to rotate, thereby driving the lifting slider 20 to slide up and down on the lifting screw 19, driving the second product fixture 10 to move up and down, thus achieving the purpose of aligning the product to be tested on the second product fixture 10 with the contoured glass 11 or the opening and closing door 15.
[0046] To limit and guide the lifting movement of the second product fixture 10, four guide rods 21 are installed on the third fixed base 16, with the four guide rods 21 distributed at the four corner positions of the third fixed base 16. Guide sleeves 22 are respectively provided on the second product fixture 10 at corresponding positions to the guide rods 21. The guide rods 21 pass through the corresponding guide sleeves 22, and the guide rods 21 and guide sleeves 22 are in sliding engagement. During the rotation of the adjusting handwheel 17, the lifting slider 20 moves up and down, driving the second product fixture 10 to move. The second product fixture 10 then causes the guide sleeves 22 to slide on the corresponding guide rods 21. The cooperation of the guide rods 21 and guide sleeves 22 limits and guides the lifting movement of the second product fixture 10, improving the stability and accuracy of the adjustment.
[0047] In other embodiments, the number of guide rods 21 can also be any other number, and this utility model does not limit this.
[0048] like Figure 3As shown, in order to facilitate the installation of the solar simulator 9, a mounting bracket 23 is provided on one side of the machine, and the solar simulator 9 is fixedly installed on the mounting bracket 23; by setting the mounting bracket 23, the solar simulator 9 can be installed above the baking oven 8, so that the solar simulator 9 can be fixed directly above the contour glass 11.
[0049] The lower end of the mounting bracket 23 is provided with multiple flexible feet 24. The flexible feet 24 can be made of flexible materials such as rubber. By installing the flexible feet 24, the mounting bracket 23 can be placed stably on the ground or tabletop. At the same time, it increases the friction between the mounting bracket 23 and the ground, prevents sliding and displacement, and improves the stability of use.
[0050] To facilitate the movement and handling of the baking oven 8, multiple casters 25 are installed at the bottom of the baking oven 8. The casters 25 allow the machine to be easily moved, thus facilitating the handling or relocation of the baking oven 8.
[0051] This automotive HUD testing equipment can test the stray light, high temperature resistance, and strong light resistance of HUD products. Compared with manual judgment, it can improve the accuracy of testing and ensure product quality. Moreover, it does not require on-vehicle testing, which improves testing efficiency and reduces testing costs. By driving the windshield to rotate and swing through the windshield fixing device 1, the tilt angle of the windshield can be changed, allowing it to simulate the windshields of different car models, meeting the testing needs of various common car models on the market, and improving the versatility of the equipment.
[0052] The above-described specific embodiments are preferred embodiments of this utility model, and are not intended to limit the specific scope of this utility model. The scope of this utility model includes but is not limited to the specific embodiments described above. All equivalent changes made in accordance with this utility model are within the protection scope of this utility model.
