[0002] With the rapid development of automotive electronics technology, in-vehicle screens are becoming increasingly common in vehicles. However, traditional in-vehicle screen electrical testing equipment has many shortcomings in terms of accuracy and stability. For example, in automated testing, the test probes often fail to make complete contact with the test points on the screen, leading to distorted test data; if manual placement is used, testing efficiency is significantly reduced. Therefore, developing a high-precision, high-stability in-vehicle screen electrical testing device is particularly urgent. Summary of the Invention

[0003] The technical problem solved by this invention is to provide a high-precision method for electrical testing of vehicle-mounted screens that improves the success rate of electrical testing.

[0004] The technical solution adopted by this invention to solve its technical problem is: a high-precision vehicle-mounted screen electrical measurement method, the steps of which are:

[0005] S100: The vehicle screen is transported to the loading platform, and the first positioning camera performs coarse positioning of the vehicle screen on the loading platform.

[0006] S200: The transport component picks up the vehicle screen based on the positioning result of the first coarse positioning camera and transports the screen to the second positioning camera at the electrical testing station.

[0007] S300: The second positioning camera performs the first fine positioning of the vehicle screen. The first transport mechanism adjusts the position of the vehicle screen according to the first fine positioning result and places the adjusted vehicle screen into the fixture on the electrical testing platform.

[0008] S400: The fixture on the electrical test bench moves the vehicle screen to below the third positioning camera. The third positioning camera positions the FPC test end of the vehicle screen. The electrical test crimping assembly on one side of the fixture adjusts the UVW position of the electrical test crimping assembly according to the positioning result of the third positioning camera.

[0009] S500: Electrical test crimping assembly is used to test the vehicle screen in the fixture.

[0010] Furthermore, the electrical testing station includes an electrical testing component and an electrical testing component driving mechanism that drives the electrical testing component to move horizontally. The electrical testing component includes the fixture and a UVW adjustment platform located on one side of the fixture. The electrical testing crimping component is mounted on the UVW adjustment platform.

[0011] The second positioning camera is located at the front end of the electrical testing platform, and the third positioning camera is located in the middle of the electrical testing platform.

[0013] Furthermore: the vehicle screen is located in the fixture, the FPC end of the vehicle screen is located on the first bottom pin template, the first drive cylinder drives the pressure head mounting bracket to move above the first bottom pin template, and the pressure head is aligned with the FPC end of the vehicle screen;

[0014] The pressure head drive mechanism drives the pressure head to move up and down, lowering it to contact the first bottom pin template, and pressing the FPC end of the vehicle screen. This ensures that both the pressure head and the test pins on the first bottom pin template are in contact with the FPC end of the vehicle screen, and performs electrical performance testing.

[0015] Furthermore, the electrical testing and crimping assembly includes a second bottom pin template for supporting the product FPC end. A rotating upper pressure head is provided at one end of the second bottom pin template. The rotating upper pressure head is hinged to one end of the second bottom pin template. A spring is installed at the hinge end of the rotating upper pressure head and the second bottom pin template. When no external force is applied, the rotating upper pressure head is in a spring-up state. A first pressure block and a first rotary motor for driving the first pressure block to rotate are provided on one side of the rotating upper pressure head. When the first rotary motor drives the first pressure block to rotate, the first pressure block drives the upper pressure head to rotate and press down.

[0016] The other end of the second bottom needle template is provided with a clamping member. The bottom of the clamping member is hinged to the second bottom needle template by a spring. The upper part of the clamping member includes a clamping end and an opening end. When no external force is applied, the clamping end applies pressure towards the second bottom needle template. A second pressure block and a second drive cylinder for driving the second pressure block to move up and down are provided on one side of the clamping member.

[0018] After the test is completed, the second drive cylinder moves the second pressure block to move up and down. The second pressure block presses down on the opening end of the clamping part, causing the clamping end to move away from the second bottom needle template. The rotating upper pressure head is released and returns to the vertical state.

[0019] Furthermore, the lens of the third positioning camera is set downwards, while the lens of the second positioning camera is set upwards.

[0020] Furthermore, it also includes a transport frame, on which an XYZ drive module is provided. The drive end of the XYZ drive module is provided with a fourth rotary motor, and the drive end of the fourth rotary motor is provided with the transport component.

[0035] To make the above-mentioned objects, features and advantages of the present invention more apparent and understandable, the specific embodiments of the present invention will be described in detail below with reference to the accompanying drawings.

[0036] like Figure 1 As shown in the figure, an embodiment of this application discloses a high-precision method for electrical testing of vehicle-mounted screens, the steps of which are as follows:

[0037] S100: The vehicle screen is transported to the loading platform 1, and the first positioning camera 8 performs coarse positioning on the vehicle screen on the loading platform 1.

[0038] S200: The transport component 7 picks up the vehicle screen according to the positioning result of the first coarse positioning camera and transports the screen to the second positioning camera 9 at the electrical test station 3;

[0039] S300: The second positioning camera 9 performs the first fine positioning of the vehicle screen. The first transport mechanism adjusts the position of the vehicle screen according to the first fine positioning result and places the adjusted vehicle screen into the fixture 303 on the electrical testing platform 3.

[0040] S400: The fixture 303 on the electrical test bench 3 moves the vehicle screen to below the third positioning camera 10. The third positioning camera 10 positions the FPC test end of the vehicle screen. The electrical test crimping assembly on one side of the fixture 303 adjusts the UVW position of the electrical test crimping assembly according to the positioning result of the third positioning camera 10.

[0041] S500: The electrical testing crimping assembly tests the vehicle screen in fixture 303.

[0042] Specifically, in the above method, in step S100, the first positioning camera 8 can quickly capture the approximate position of the vehicle screen, providing basic data for subsequent precise handling. In step S200, the handling component 7 accurately picks up and handles the vehicle screen based on the data from the first positioning camera 8. In step S300, the second positioning camera 9 further precisely adjusts the position of the vehicle screen to ensure that it is accurately placed in the fixture 303. During the placement of the vehicle screen into the electrical testing component 302, some accuracy loss may occur due to minor vibrations. Therefore, in step S400, the third positioning camera 10 can precisely position the FPC test end of the vehicle screen. Based on the data from the third positioning camera 10, the electrical testing crimping component adjusts the UVW position to ensure precise alignment of the test probes and test points. Finally, in step S500, the electrical testing crimping component begins testing the vehicle screen. The high-precision positioning in the preceding steps ensures the accuracy and stability of the test results throughout the entire testing process. This method not only improves the accuracy of testing but also significantly enhances testing efficiency, providing strong technical support for automotive screen manufacturers. In actual production testing, the electrical test success rate of this device can reach 99.5%.

[0043] In this embodiment, the electrical testing platform 3 includes an electrical testing component 302 and an electrical testing component driving mechanism 301 that drives the electrical testing component 302 to move horizontally. The electrical testing component 302 includes the fixture 303 and a UVW adjustment platform 305 located on one side of the fixture 303. The electrical testing crimping component is mounted on the UVW adjustment platform 305. The second positioning camera 9 is located at the front end of the electrical testing platform 3, and the third positioning camera 10 is located in the middle of the electrical testing platform 3.

[0044] Specifically, when the vehicle screen moves to a position below the third camera, the third precision positioning camera performs a final, precise positioning of the vehicle screen. After positioning, the UVW adjustment platform 305 begins operation, making minor three-dimensional adjustments to the electrical testing crimping assembly based on data feedback from the third positioning camera 10. This ensures that the test probes on the electrical testing crimping assembly are accurately aligned with the test points of the FPC on the vehicle screen. After the UVW adjustment platform 305 completes its adjustments, the electrical testing crimping assembly begins operation to perform electrical performance testing on the vehicle screen under test. During the test, the electrical testing assembly 302 collects and analyzes the test data to evaluate whether the performance of the vehicle screen meets the expected standards.

[0045] In this structure, since electrical tests are required for different vehicle screens, the product fixture 303 needs to be disassembled and replaced frequently. In this structure, the electrical testing crimping assembly is adjusted to adapt to the position of the product. This method allows the fixture 303 and the crimping head 308 in the electrical testing crimping assembly to be disassembled when changing the test product, without the need to disassemble and adjust the UVW adjustment platform 305.

[0046] Specifically, electrical testing crimping assemblies can take many forms; the following are two specific structural forms:

[0047] The first embodiment is as follows: the electrical testing crimping assembly includes a first bottom pin template 306 for supporting the product FPC end, a crimping head 308 mounting bracket 307 is provided above the first bottom pin template 306, the crimping head 308 mounting bracket 307 is provided with a crimping head 308 and a crimping head drive mechanism 309 for driving the crimping head 308 to move up and down, and a first drive cylinder 310 is provided on the UVW adjustment platform 305 for driving the crimping head 308 mounting bracket 307 to move horizontally.

[0048] It should be explained that when changing the testing product, the first bottom needle template 306 and the pressure head 308 must be replaced simultaneously.

[0049] Specifically, during the test, the vehicle screen is located in the fixture 303, the FPC end of the vehicle screen is located on the first bottom pin template 306, the first drive cylinder 310 drives the pressure head 308 mounting bracket 307 to move above the first bottom pin template 306, and the pressure head 308 is aligned with the FPC end of the vehicle screen.

[0050] The pressure head drive mechanism 309 drives the pressure head 308 to move up and down, lowering the pressure head 308 to contact the first bottom pin template 306, and pressing the FPC end of the vehicle screen, so that the test pins on the pressure head 308 and the first bottom pin template 306 are in contact with the FPC end of the vehicle screen for electrical performance testing.

[0051] The second embodiment is as follows: The electrical testing and crimping assembly includes a second bottom pin template 311 for supporting the product FPC end. One end of the second bottom pin template 311 is provided with a rotating upper pressure head 312308. The rotating upper pressure head 312308 is hinged to one end of the second bottom pin template. A spring is installed at the hinge end of the rotating upper pressure head 312308 and the second bottom pin template. When no external force is applied, the rotating upper pressure head 312308 is in a spring-up state. A first pressure block 313 and a first rotary motor 314 for driving the first pressure block 313 to rotate are provided on one side of the rotating upper pressure head 312308. When the first rotary motor 314 drives the first pressure block 313 to rotate, the first pressure block 313 drives the upper pressure head 308 to rotate and press down.

[0052] The other end of the second bottom needle template 311 is provided with a clamping member 315. The bottom of the clamping member 315 is hinged to the second bottom needle template 311 by a spring. The upper part of the clamping member 315 includes a clamping end and an opening end. When no external force is applied, the clamping end applies pressure to the second bottom needle template 311. A second pressing block 316 and a second driving cylinder 317 that drives the second pressing block 316 to move up and down are provided on one side of the clamping member 315. When the second pressing block 316 presses down on the opening end, the clamping end moves away from the second bottom needle template 311.

[0053] Specifically, during testing, the vehicle screen is located in the product fixture 303, and the FPC end of the vehicle screen is located on the second bottom pin template 311. The first rotary motor 314 drives the first pressure block 313 to rotate, and the first pressure block 313 drives the rotating upper pressure head 312308 to rotate and press down, pressing the rotating upper pressure head 312308 into contact with the second bottom pin template 311. The test pins on the rotating upper pressure head 312308 and the second bottom pin template 311311 contact the FPC end of the vehicle screen to perform electrical performance testing.

[0054] After the test is completed, the second drive cylinder 317 moves the second pressure block 316 to move up and down. The second pressure block 316 presses down on the opening end of the clamping member 315, causing the clamping end to move away from the second bottom needle template 311. The rotating upper pressure head 312308 is released and returns to the vertical state, so that the vehicle screen can be removed smoothly.

[0055] Both of the above-mentioned test structures can effectively crimp the FPC end of the vehicle screen, ensuring the accuracy and stability of electrical performance testing. In practical applications, the appropriate test structure can be selected based on the specific size and shape of the vehicle screen, as well as the testing requirements.

[0056] In this embodiment, the lens of the third positioning camera 10 is set downwards, and the lens of the second positioning camera 9 is set upwards.

[0057] Specifically, during operation, the transport component 7 moves the vehicle screen above the second positioning camera 9, allowing the second positioning camera 9 to take a picture of the vehicle screen from below and perform a second positioning of the vehicle screen. After the vehicle screen is on the fixture 303, it moves to the area below the third positioning camera 10 under the action of the fixture 303, allowing the third positioning camera 10 to take a picture of the vehicle screen from above and perform a third positioning of the vehicle screen.

[0058] The aforementioned arrangement of the second positioning camera 9 and the third positioning camera 10 not only ensures positioning accuracy but also significantly improves positioning efficiency. The second positioning camera 9 is located at the front end of the electrical testing platform 3, with its lens facing upwards, facilitating a second precise positioning immediately after the vehicle-mounted screen is moved onto the platform 3, providing a foundation for subsequent operations. The third positioning camera 10 is located in the middle of the electrical testing platform 3, with its lens facing downwards, enabling final precise positioning when the vehicle-mounted screen is placed in the fixture 303 and moved beneath it, ensuring perfect alignment between the test probe and the test point. This coordinated positioning method not only simplifies the positioning process but also reduces positioning errors, further improving the accuracy and stability of the test.

[0059] In this embodiment, a transport frame 4 is also included. An XYZ drive module 5 is provided on the transport frame 4. A fourth rotary motor 6 is provided at the drive end of the XYZ drive module 5. The transport component 7 is provided at the drive end of the fourth rotary motor 6. The first positioning camera 8 is provided on one side of the transport component 7. This enables the transport component 7 to rotate and adjust the product and transport the vehicle screen to the electrical testing platform 3.

[0060] Specifically, driven by the XYZ drive module 5, the transport component 7 can make precise displacement adjustments in the X, Y, and Z directions, ensuring that the vehicle-mounted screen can be accurately transported to the predetermined position at the electrical testing platform 3. Simultaneously, the fourth rotary motor 6 enables the transport component 7 to rotate, further improving the flexibility and accuracy of the transport process.

[0061] In this embodiment, the transport component 7 includes a suction cup mounting bracket 701, on which a plurality of suction nozzle units 702 are provided.

[0062] Specifically, the suction cup mounting bracket 701 can be provided with multiple waist-shaped grooves, and the suction nozzle unit 702 is installed in the waist-shaped grooves by fasteners. The suction nozzle unit 702 can be adjusted according to the shape and size of different vehicle screens to ensure that it can firmly attach to the vehicle screen and avoid slipping or damage during transportation.

[0063] In this embodiment, the feeding platform 1 includes a feeding conveyor line, and a baffle plate 2 is provided at the end of the feeding conveyor line.

[0064] Specifically, when the vehicle screen moves to the end of the feeding conveyor line, the baffle 2 will prevent the vehicle screen from moving forward. At this time, the first handling component 7 will move the vehicle screen from the feeding conveyor line to the electrical testing station 3 for testing.

[0065] The specific embodiments described above further illustrate the purpose, technical solution, and beneficial effects of the present invention. It should be understood that the above descriptions are merely specific embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
