Description

Technical Field

[0001] This invention relates to the field of automation equipment technology, and more specifically to a testing device for dashcam cameras. Background Technology

[0002] A dashcam is an instrument used to record video and audio information while a vehicle is in motion. After installation, it records video and audio of the entire driving process, providing evidence in case of traffic accidents. For those who enjoy road trips, it can also be used to record the process of overcoming challenging obstacles. It records video while driving, simultaneously capturing time, speed, and location—essentially a "black box."

[0003] Figure 1 , Figure 2 A dashcam is shown, featuring a main camera S1 on its front end and a telephoto lens S2 and a wide-angle lens S3 on its rear end. Before leaving the factory, the dashcam undergoes various tests on its main camera S1, telephoto lens S2, and wide-angle lens S3, including white card testing (to check for dead pixels, dirt, color reproduction, etc.), black card testing (to check for bright spots, noise, etc.), and resolution testing (to evaluate the lens's resolving power), to ensure that each camera can capture clear and stable images.

[0004] Currently, most dashcam camera testing in the industry relies on manual operation. Operators need to manually place the dashcam at different test stations, perform various tests, and rely on visual observation of the screen or images for judgment. This manual testing method has significant drawbacks: First, the testing efficiency is low, with manual handling and switching of test items being time-consuming. Second, the consistency of test results is difficult to guarantee, as misjudgments or omissions are easily caused by operator fatigue, differences in experience, or subjective judgment, affecting the stability of product quality. Therefore, it is necessary to design a device capable of automatically testing dashcam cameras. Summary of the Invention

The terms "first," "second," etc., in the specification, claims, or foregoing drawings are used to distinguish different objects, not to describe a particular order.

[0019] In this invention, the reference to "embodiment" means that a specific feature, structure, or characteristic described in connection with an embodiment may be included in at least one embodiment of the invention. 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.

[0020] 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.

[0021] like Figure 1-14 As shown, a dashcam camera testing device includes a machine base 100 and a controller 200. The machine base 100 has multiple testing stations and a protective cover 300 covering each testing station. The protective cover 300 has multiple openable and closable protective doors 301. Opening the protective doors 301 facilitates equipment inspection, debugging, and maintenance; closing the protective doors 301 creates a sealed space within the protective cover 300 for testing the dashcam camera. The protective cover 300 has loading / unloading ports 302 and a shielding door mechanism 400. The loading / unloading ports 302 are used for manual or robotic loading / unloading of the dashcam, and the shielding door mechanism 400 is used to open or close the loading / unloading ports 302.

[0022] When loading and unloading are required, the loading / unloading port 302 is opened via the shielding door mechanism 400. During testing, the loading / unloading port 302 is sealed via the shielding door mechanism 400, thus creating a sealed space inside the protective cover 300 to facilitate testing of the dashcam's camera. Specifically, as follows... Figure 6 As shown, the shielding door mechanism 400 includes an opening / closing cylinder 401, which is fixed to the protective cover 300. A sealing door 402 is connected to the output end of the opening / closing cylinder 401. The opening / closing cylinder 401 can drive the sealing door 402 to move up and down, thereby opening or blocking the feed inlet / outlet 302. In this embodiment, there are two opening / closing cylinders 401, symmetrically distributed on the left and right sides of the sealing door 402. Protective light curtains 500 are also installed on the protective cover 300 on both sides of the feed inlet / outlet 302 to detect whether any objects or personnel are blocking the doorway, providing safety protection.

[0023] The controller 200 includes a display screen 201 and control buttons 202 mounted on the protective cover 300. The display screen 201 can be used to display various operating parameters of the equipment and can also be used for debugging and setting the equipment. The control buttons 202 can be used to control the start and stop of the equipment.

[0024] The machine tool 100 is equipped with a transport module 1 connected to a controller 200. A product fixture 2 is located at the output end of the transport module 1, used to mount the dashcam to be tested. The machine tool 100 is equipped with a main camera testing component and a secondary camera testing component, located on the left and right sides of the transport module 1, respectively. The main camera testing component includes a main camera white card testing mechanism 3, a main camera black card testing mechanism 4, and a main camera resolution testing mechanism 5, arranged sequentially along the movement direction of the transport module 1. The secondary camera testing component includes a wide-angle resolution testing mechanism 6, a telephoto black card testing mechanism 7, a telephoto wide-angle white card testing mechanism 8, a telephoto resolution testing mechanism 9, and a wide-angle black card testing mechanism 10, arranged sequentially along the movement direction of the transport module 1. The transport module 1 can transport the product fixture 2 to the processing positions of the loading / unloading port 302, the main camera white card testing mechanism 3, the main camera black card testing mechanism 4, the main camera resolution testing mechanism 5, the wide-angle resolution testing mechanism 6, the telephoto black card testing mechanism 7, the telephoto wide-angle white card testing mechanism 8, the telephoto resolution testing mechanism 9, and the wide-angle black card testing mechanism 10, respectively.

[0025] Initially, the product fixture 2 is located at the loading / unloading port 302, which is open. A person or a robot uses the loading / unloading port 302 to install the dashcam onto the product fixture 2, establishing a communication connection between the dashcam and the equipment controller 200. During testing, the loading / unloading port 302 is first closed by the shielded door machine. Then, the transport module 1 drives the product fixture 2, carrying the dashcam, to the testing positions of the main camera white card testing mechanism 3, the main camera black card testing mechanism 4, and the main camera resolution testing mechanism 5. The main camera white card testing mechanism 3 performs white card and infrared tests on the main camera of the dashcam on the product fixture 2. The main camera black card testing mechanism 4 performs black card tests on the main camera of the dashcam on the product fixture 2. Finally, the main camera resolution testing mechanism 5 performs resolution tests on the main camera of the dashcam on the product fixture 2. After the main camera of the dash cam completes testing, the transport module 1 resets, and the drive product fixture 2 transports the dash cam to the testing positions of the wide-angle resolution testing mechanism 6, the telephoto black card testing mechanism 7, the telephoto wide-angle white card testing mechanism 8, the telephoto resolution testing mechanism 9, and the wide-angle black card testing mechanism 10. The wide-angle resolution testing mechanism 6 tests the resolution of the dash cam's wide-angle lens, the telephoto black card testing mechanism 7 tests the telephoto lens of the dash cam with a black card, the telephoto wide-angle white card testing mechanism 8 tests the telephoto and wide-angle lenses of the dash cam with white cards, the telephoto resolution testing mechanism 9 tests the resolution of the telephoto lens of the dash cam, and the wide-angle black card testing mechanism 10 tests the wide-angle lens of the dash cam with a black card. Once all tests are completed, the product fixture 2, driven by the transport module 1, moves the tested dashcam to the loading / unloading port 302. Then, the shielding door mechanism 400 opens the loading / unloading port 302, and the tested dashcam is removed from the product fixture 2 by manual labor or a robotic arm, completing one round of testing.

[0026] like Figure 7 As shown, the conveying module 1 includes a conveying motor 11 and a conveying lead screw module 12. The output end of the conveying motor 11 is connected to the conveying lead screw module 12, and a conveying slider 13 is connected to the output end of the conveying lead screw module 12. The product fixture 2 is fixedly mounted on the conveying slider 13. By controlling the forward and reverse rotation of the conveying motor 11, the product fixture 2 can be driven to move linearly back and forth along the conveying lead screw module 12, so that the product fixture 2 can be accurately stopped at the test positions of the loading / unloading port 302, the main camera white card test mechanism 3, the main camera black card test mechanism 4, the main camera resolution test mechanism 5, the wide-angle resolution test mechanism 6, the telephoto black card test mechanism 7, the telephoto wide-angle white card test mechanism 8, the telephoto resolution test mechanism 9, and the wide-angle black card test mechanism 10.

[0027] like Figure 8-9As shown, the product fixture 2 includes a fixture fixing base 21, which is connected to the output end of the conveying screw module 12. A rotary swing module 22 is mounted on the fixture fixing base 21, and a fixture mounting block 23 is mounted on the output end of the rotary swing module 22. The rotary swing module 22 can drive the fixture mounting block 23 to rotate and swing. The fixture mounting block 23 is rotatably and limitably connected to the fixture fixing base 21. A product placement groove 231 is provided on the fixture mounting block 23, and a product clamping module 24 is provided at a corresponding position on the fixture mounting block 23 corresponding to the product placement groove 231. The product clamping module 24 is connected to the product placement groove 231.

[0028] During testing, a person or a robotic arm places the dashcam into the product mounting slot 231, and the product clamping module 24 clamps the dashcam, fixing it within the slot 231 to prevent displacement during testing. Then, the transport module 1 drives the fixture fixing base 21, carrying the fixture mounting block 23 and the dashcam, to each testing station. When testing the dashcam's main camera, the rotation and swing module 22 drives the fixture mounting block 23 to rotate and swing, aligning the dashcam's main camera with the main camera test component within the product mounting slot 231. After testing the main camera, the rotation and swing module 22 drives the fixture mounting block 23 to rotate and swing in the opposite direction, aligning the wide-angle and telephoto lenses with the secondary camera test component within the product mounting slot 231. The telephoto and wide-angle lenses are then tested.

[0029] During testing, the fixture mounting block 23 is used to directly support and secure the dash cam. Multiple product limiting blocks 25 are fixedly mounted on the upper surface of the fixture mounting block 23 using screws. These product limiting blocks 25 together form a product placement groove 231 that matches the shape of the dash cam under test. In other embodiments, the product placement groove 231 may also be a slot formed on the upper surface of the fixture mounting block 23.

[0030] The product clamping module 24 includes a clamping cylinder 241, which is fixedly connected to the fixture mounting block 23. A product clamping block 242 is provided on the output end of the clamping cylinder 241. The clamping cylinder 241 can drive the product clamping block 242 to extend into or out of the product placement slot 231. A material receiving sensor 26 is provided inside the product placement slot 231 to detect whether there is a product inside. During processing, when the vehicle recorder is placed in the product placement slot 231, the material receiving sensor 26 detects the vehicle recorder and sends a feedback signal. This then controls the clamping cylinder 241 to move, driving the product clamping block 242 into the product placement slot 231. The product clamping block 242 presses the vehicle recorder against the product limiting block 25 on the opposite side, thus fixing the vehicle recorder within the product placement slot 231.

[0031] In this embodiment, the rotating swing module 22 includes a rotating swing motor 221, which is fixed on the clamp mounting base 21. The output end of the rotating swing motor 221 is connected to a rotary table 222, and the output flange of the rotary table 222 is fixedly connected to the clamp mounting block 23. When it is necessary to drive the clamp mounting block 23 to rotate and swing, the rotating swing motor 221 is controlled to work, driving the rotary table 222 to rotate. The rotary table 222 will drive the clamp mounting block 23 and the dashcam to rotate and swing, thereby adjusting the orientation angle of the dashcam.

[0032] To achieve precise control over different test angles, the fixture mounting block 23 is rotatably connected to the fixture fixing base 21 via a rotating shaft 27 on the side away from the rotary swing motor 221. A sensing lever 28 is fixedly mounted on the rotating shaft 27. Two position sensors 29 are mounted on the fixture fixing base 21 along the rotation path of the sensing lever 28 via an adjustable mounting bracket. The positions of these two position sensors 29 can be adjusted according to the required swing angle for the test. When the rotary swing motor 221 drives the fixture mounting block 23 to rotate, the sensing lever 28 rotates accordingly. When it triggers one of the position sensors 29, it indicates that the fixture mounting block 23 has rotated to the predetermined angle, and the control system then stops the rotary swing motor 221, thus ensuring the accuracy of the angle.

[0033] If different types of dashcams need to be tested, the position of the position sensor 29 on the clamp mounting base 21 can be adjusted, allowing the clamp mounting block 23 to rotate and swing at different angles. The position sensor 29 adopts an adjustable structure design, enabling the product clamp 2 to adapt to various dashcam products of different models and sizes, thus improving versatility.

[0034] In addition, to facilitate on-site debugging and observation, swing indicator marks 211 are engraved on the fixture fixing base 21, and a swing pointer 210 is provided at the corresponding position on the fixture mounting block 23. Debugging personnel can quickly set and calibrate the initial position and swing angle of the product fixture 2 by observing the alignment of the pointer with the marks.

[0035] like Figure 10As shown, the main camera white card testing mechanism 3 includes a horizontal push module 31, which is fixed on the machine base 100. The horizontal push module 31 can be any existing linear drive device such as a cylinder, electric cylinder, or motor screw structure, and the present invention does not limit this. A first mounting bracket 32 ​​is connected to the output end of the horizontal push module 31, and a hemispherical light source 33 is mounted on the first mounting bracket 32. The horizontal push module 31 can drive the hemispherical light source 33 to be mounted on the periphery of the main camera of the dashcam on the product fixture 2. The side wall of the hemispherical light source 33 near the product fixture 2 is a concave hemispherical shape, and the inner side wall of the hemispherical surface is coated with an infrared reflective coating. In order to ensure smooth movement and accurate positioning, a horizontal push guide rail 34 is provided on the machine base 100, and the bottom of the first mounting bracket 32 ​​is slidably engaged with the horizontal push guide rail 34. Meanwhile, buffer limiters 35 are provided on both the front and rear sides of the movement path of the first mounting frame 32. The buffer limiters 35 are fixedly installed on the machine base 100. The horizontal push module 31 can drive the first mounting frame 32 to move forward or backward and abut against the corresponding buffer limiters 35 respectively, so as to achieve buffering and precise positioning at the end of the stroke.

[0036] During testing, after the transport module 1 transports the product fixture 2 and the dashcam to the main camera white card testing station, the rotary table 222 is first driven to rotate by the rotary swing motor 221. The rotary table 222 drives the fixture mounting block 23 and the dashcam to rotate and swing until the dashcam's main camera is aligned with the center of the hemispherical light source 33. Then, the horizontal push module 31 drives the first mounting bracket 32 ​​and the hemispherical light source 33 to move towards the product fixture 2 until the opening end of the hemispherical light source 33 covers the dashcam's main camera. During the white card test, the hemispherical light source 33 is lit up to form a uniform bright field on its inner wall. The dashcam's main camera captures and analyzes the image to achieve the white card test of the dashcam's main camera. During the infrared test, the hemispherical light source 33 is turned off to put the camera in a dark environment, and then the dashcam's main camera is triggered to emit infrared light. Infrared light is reflected back to the camera after it shines on the infrared reflective coating on the inner wall of the hemispherical light source 33. The camera captures the reflected infrared signal and performs image analysis to evaluate its infrared performance.

[0037] like Figure 11-12As shown, the main camera resolution testing mechanism 5 includes a second mounting bracket 51, which is fixed on the machine base 100. A main camera repeater lens 52 is mounted on the second mounting bracket 51, and the optical axis of the main camera repeater lens 52 can be aligned with the main camera of the dashcam on the product fixture 2. A main camera resolution light source is provided on the side of the second mounting bracket 51 away from the transport module 1. The main camera resolution light source includes a light source fixing bracket 53, and a light-emitting component 54 (such as a uniform backlight panel and a resolution test chart) is provided inside the light source fixing bracket 53. During testing, the transport module 1 can drive the product fixture 2 to transport the dashcam to the position corresponding to the main camera resolution testing mechanism 5, and the dashcam on the product fixture 2 can be aligned with the main camera repeater lens 52. During testing, the main camera of the dashcam focuses on the test chart on the light-emitting component 54 through the main camera repeater lens 52, and after acquiring the image, its resolution is calculated by analysis software. This realizes the testing process for the main camera resolution of the dashcam.

[0038] To accommodate the testing needs of different products, a horizontal slide rail 55 is provided on the machine 100, and the bottom of the light source mounting bracket 53 is slidably connected to the horizontal slide rail 55. A limit locking block 56 is provided on the light source mounting bracket 53, and an adjusting screw 57 is screwed onto the limit locking block 56. Tightening the adjusting screw 57 causes the limit locking block 56 to press firmly against the horizontal slide rail 55, thereby fixing the position of the light source mounting bracket 53; loosening the adjusting screw 57 allows the light source mounting bracket 53 to move along the horizontal slide rail 55. By adjusting the movement of the light source mounting bracket 53 on the horizontal slide rail 55, the distance between the light-emitting component 54 and the main camera repeater lens 52 can be changed, thus making it suitable for the camera testing needs of different dashcams and improving the versatility of the equipment.

[0039] To improve the accuracy of adjustment, an indicator scale 58 is provided next to the transverse slide rail 55 on the machine tool 100, and a pointer 59 is fixed on the light source mounting bracket 53, with the pointer 59 pointing to the indicator scale 58. By checking the alignment between the pointer 59 and the indicator scale 58, the position of the main camera resolution light source can be accurately located to meet the testing requirements of different product models.

[0040] like Figure 11As shown, the main camera black card testing mechanism 4 is integrated on the second mounting bracket 51 of the main camera resolution testing mechanism 5. The main camera black card testing mechanism 4 includes a main camera black card testing drive component 41 (such as a cylinder or electric push rod), which is fixed to the second mounting bracket 51. A main camera test black card 42 is connected to the output end of the main camera black card testing drive component 41. During the test, when the transport module 1 drives the product fixture 2 to transport the dashcam to the position corresponding to the main camera black card testing mechanism 4, the main camera black card testing drive component 41 drives the main camera test black card 42 to extend, making it closely adhere to or very close to the main camera lens of the dashcam on the product fixture 2, creating a completely dark environment. The dashcam's main camera acquires images in this environment to detect bright spots and noise, thus realizing the black card testing process for the main camera.

[0041] like Figure 13 As shown, the wide-angle resolution testing mechanism 6 includes a third mounting frame 61, which is connected to the machine base 100. A wide-angle repeater lens 62 is provided on the third mounting frame 61. The transport module 1 can drive the dashcam on the product fixture 2 to connect with the wide-angle repeater lens 62. A wide-angle resolution light source 63 is provided on the side of the third mounting frame 61 away from the transport module 1. The wide-angle lens of the dashcam on the product fixture 2 can capture the wide-angle resolution light source 63 through the wide-angle repeater lens 62. During the testing process, after the main camera of the dash cam is tested, the rotating swing module 22 drives the fixture mounting block 23 to rotate and swing the dash cam, so that the wide-angle lens and telephoto lens of the dash cam on the fixture mounting block 23 are aligned with the secondary camera test component. Then, the transport module 1 drives the product fixture 2 to move the dash cam to the test position of the wide-angle resolution testing mechanism 6, so that the wide-angle lens of the dash cam on the product fixture 2 is aligned with the wide-angle repeater lens 62. The wide-angle lens of the dash cam focuses on the test chart on the wide-angle resolution light source 63 through the wide-angle repeater lens 62, and after the image is acquired, its resolution is calculated by the analysis software to complete the resolution test process of the wide-angle lens of the dash cam.

[0042] In this embodiment, the structure of the wide-angle resolution light source 63 is the same as that of the main camera resolution light source, so its specific structure will not be described in detail here.

[0043] The third mounting bracket 61 is equipped with a repeater mounting plate 64, on which a wide-angle repeater 62 is mounted. The repeater mounting plate 64 has multiple elongated through holes 65 on its left and right sides. The repeater mounting plate 64 is fixedly connected to the third mounting bracket 61 by connecting screws. During installation, the connecting screws pass through the elongated through holes 65 and are tightened onto the third mounting bracket 61, thus securing the repeater mounting plate 64 to the third mounting bracket 61. The repeater mounting plate 64 has adjusting blocks 66 on its upper and lower sides, each with a repeater adjusting screw 67. One end of the repeater adjusting screw 67 abuts against the side wall of the repeater mounting plate 64. By rotating the repeater adjusting screw 67, the installation position and height of the repeater mounting plate 64 can be adjusted, thereby adjusting the installation position of the wide-angle repeater 62 to meet the testing requirements of different products.

[0044] During adjustment, first loosen the connecting screws between the repeater mounting plate 64 and the third mounting bracket 61, then rotate the repeater adjustment screw 67. To raise the wide-angle repeater 6, tighten the repeater adjustment screw 67 below the repeater mounting plate 64 and loosen the repeater adjustment screw 67 above the repeater mounting plate 64. The repeater adjustment screw 67 below the repeater mounting plate 64 will push the repeater mounting plate 64 upwards. After adjusting to the appropriate position, retighten the repeater adjustment screw 67 and the connecting screws. Conversely, to lower the wide-angle repeater 6, loosen the repeater adjustment screw 67 below the repeater mounting plate 64 and tighten the repeater adjustment screw 67 above the repeater mounting plate 64, causing the repeater adjustment screw 67 above the repeater mounting plate 64 to push the repeater mounting plate 64 downwards.

[0045] like Figure 13 As shown, the telephoto lens testing mechanism 7 is integrated onto the third mounting bracket 61 of the wide-angle resolution testing mechanism 6. The telephoto lens testing mechanism 7 includes a telephoto lens testing drive component 71 (such as a cylinder or electric push rod), which is fixed to the third mounting bracket 61. A telephoto lens testing black card 72 is connected to the output end of the telephoto lens testing drive component 71. During testing, when the transport module 1 drives the product fixture 2 to transport the dashcam to the position corresponding to the telephoto lens testing mechanism 7, the telephoto lens testing drive component 71 drives the telephoto lens testing black card 72 to extend, making it closely adhere to or very close to the telephoto lens of the dashcam on the product fixture 2, creating a completely dark environment. The dashcam's telephoto lens acquires images in this environment to detect bright spots and noise, thus realizing the telephoto lens black card testing process.

[0046] like Figure 14As shown, the telephoto resolution testing mechanism 9 includes a fourth mounting bracket 91, which is connected to the machine tool 100. A push cylinder 92 is provided on the fourth mounting bracket 91, and a telephoto repeater lens 93 is provided on the output end of the push cylinder 92. The transport module 1 can drive the dashcam on the product fixture 2 to align with the telephoto resolution testing mechanism 9. The push cylinder 92 can drive the telephoto repeater lens 93 to connect with the telephoto lens of the dashcam on the product fixture 2. A telephoto resolution light source 94 is provided on the side of the fourth mounting bracket 91 away from the transport module 1. The telephoto lens of the dashcam on the product fixture 2 can capture the telephoto resolution light source 94 through the telephoto repeater lens 93.

[0047] During the test, when the transport module 1 drives the product fixture 2 to move the dashcam to the test position of the telephoto resolution testing mechanism 9, the cylinder 92 is pushed to extend the telephoto repeater 93, so that the telephoto lens of the dashcam on the product fixture 2 is aligned and connected with the telephoto repeater 93. The telephoto lens of the dashcam focuses on the test chart on the telephoto resolution light source 94 through the telephoto repeater 93, and after the image is acquired, its resolution is calculated by the analysis software to complete the resolution test process of the dashcam's telephoto lens.

[0048] In this embodiment, the structure of the telephoto resolution light source 94 is the same as that of the main camera resolution light source, so its specific structure will not be described in detail here.

[0049] like Figure 14 As shown, the telephoto and wide-angle white card testing mechanism 8 includes a push cylinder 81 connected to a fourth mounting bracket 91. A white light source 82 is mounted on the output end of the push cylinder 81. The transport module 1 drives the wide-angle and telephoto lenses of the dashcam on the product fixture 2 to align with the white light source 82. The push cylinder 81 drives the white light source 82 to move closer to or further away from the transport module 1. The telephoto and wide-angle white card testing mechanism 8 is used to perform white card testing on the telephoto and wide-angle lenses of the dashcam on the product fixture 2. In actual testing, after the transport module 1 drives the product fixture 2 to align the wide-angle lens of the dashcam with the white light source 82, the push cylinder 81 works to extend the white light source 82, connecting the wide-angle lens of the dashcam with the white light source 82. Then, the white light source 82 is lit, and the wide-angle lens of the dashcam captures and analyzes the image to achieve the white card testing of the wide-angle lens of the dashcam. After the test is completed, the push cylinder 81 drives the white light source 82 to retract, causing the wide-angle lens of the dashcam to detach from the white light source 82. Then, the transport module 1, driven by the product fixture 2, moves the dashcam to another workstation. The white card test process for the telephoto lens is the same as that for the wide-angle lens, and will not be repeated in this article.

[0050] like Figure 14As shown, the wide-angle black card testing mechanism 10 includes a wide-angle black card mounting base 101, which is connected to the fourth mounting bracket 91. A wide-angle test black card 102 is mounted on the mounting base 101. The transport module 1 can drive the wide-angle lens of the dashcam on the product fixture 2 to align with the wide-angle test black card 102. During testing, the motion module can drive the product fixture 2 to move the dashcam to the corresponding position in the wide-angle black card testing mechanism 10 until the wide-angle lens of the dashcam is aligned with the wide-angle test black card 102. The wide-angle test black card 102 in front of the wide-angle lens creates a completely dark environment. The wide-angle lens of the dashcam captures images in this environment to detect bright spots and noise, thus realizing the black card testing process for the wide-angle lens.

[0051] The workflow of this dashcam camera testing equipment is as follows: Initially, the product fixture 2 is positioned at the loading / unloading port 302. A manual or robotic arm installs the vehicle recorder into the product placement slot, establishing a communication connection between the recorder and the controller 200. Then, the shielding door mechanism 400 closes the loading / unloading port 302, creating a sealed space within the protective cover 300 to reduce interference from external light. During testing, the transport module 1 drives the product fixture 2, carrying the vehicle recorder, to various testing stations for testing.

[0052] During testing, the main camera is tested first. The rotating swing module 22 drives the fixture mounting block 23 to rotate and swing the dashcam, aligning the dashcam's main camera with the main camera test component. Then, the transport module 1 drives the product fixture 2 to sequentially transport the dashcam to the main camera white card test mechanism 3, the main camera black card test mechanism 4, and the main camera resolution test mechanism 5, completing the main camera testing process.

[0053] After the main camera's resolution test is completed, the rotating swing module 22 drives the fixture mounting block 23 to rotate and swing the dashcam in the opposite direction, resetting the dashcam to its initial position and aligning the wide-angle and telephoto lenses of the dashcam with the secondary camera test components. Then, the transport module 1 drives the product fixture 2 to sequentially transport the dashcam to the wide-angle resolution test mechanism 6, the telephoto black card test mechanism 7, the telephoto wide-angle white card test mechanism 8, the telephoto resolution test mechanism 9, and the wide-angle black card test mechanism 10. These mechanisms complete the testing process for the dashcam's telephoto and wide-angle lenses.

[0054] After the wide-angle black card testing mechanism 10 completes the test, the product fixture 2, driven by the transport module 1, moves the dashcam to the loading / unloading port 302. The loading / unloading port 302 is then opened by the shielding door mechanism 400, and the tested dashcam is removed from the product fixture 2 by a person or a robotic arm. This completes the testing process for one dashcam. The above actions are repeated to achieve continuous testing.

[0055] This dashcam camera testing equipment has the following beneficial effects: 1. By setting up transport modules and product fixtures, the vehicle recorder can be automatically transported to various test stations, realizing an automated testing process, which greatly reduces manual operation time and costs, and improves testing efficiency by 3-5 times compared to manual operation.

[0056] 2. By setting up main camera test components and secondary camera test components, white card tests, black card tests, and resolution tests are conducted on the main camera, telephoto lens, and wide-angle lens respectively. The test items are comprehensive, which can ensure that the image quality of each lens meets the factory standards.

[0057] 3. The design of the protective cover and protective light grid improves the safety of the equipment, prevents external light from interfering with test results, and facilitates maintenance and repair. The shielded door mechanism can effectively control the opening and closing of the loading and unloading ports, avoiding external interference during the testing process.

[0058] 4. The main camera white card testing mechanism uses a hemispherical light source with an infrared reflective coating, providing a uniform lighting environment to ensure the accuracy of white card testing. In the main camera resolution testing mechanism, the main camera resolution light source is adjustable in position and precisely positioned using pointers and scale markings to adapt to different testing needs and improve testing accuracy.

[0059] 5. The product fixture adopts a rotating swing module, which can adjust the angle of the dashcam to ensure accurate alignment of each lens with the testing mechanism, thus ensuring the reliability of the test. The product clamping module can firmly fix the product and prevent displacement during the test.

[0060] 6. The secondary camera test component integrates multiple test mechanisms, has a compact structure, and achieves multi-item testing within a limited space, reducing the equipment's footprint.
