Description

Technical Field

[0001] This utility model belongs to the field of automotive controller testing technology, and in particular relates to an online testing device for automotive controllers. Background Technology

[0002] In the manufacturing process of automotive controllers, pre-shipment performance simulation testing is a crucial step in ensuring product quality and reliability. Traditional testing methods generally rely on manual operation: operators need to manually move the automotive controller under test to the designated testing station, position and clamp it on the workbench. After positioning, operators must manually connect the connectors on the testing equipment to the corresponding interfaces on the side of the controller to establish electrical connection before the testing program can be started. This highly manual testing process has significant limitations.

[0003] First, the entire process involves multiple manual handling, positioning, clamping, and insertion operations. The steps are cumbersome, labor-intensive, and time-consuming, directly hindering testing efficiency and failing to meet the demands of modern production lines for high capacity and rapid turnaround. Second, in the critical connector mating stage, manual operation is highly prone to incomplete insertion, poor contact, or even misalignment. Such poor mating can not only force the testing process to be interrupted, requiring manual intervention for troubleshooting and re-insertion, wasting valuable time, but more seriously, it can directly lead to unstable or interrupted test signal transmission, resulting in incorrect test results or failure to complete the test, affecting the accuracy of the test and the determination of product pass rate.

[0004] Therefore, there is an urgent need for an online testing device for automotive controllers that can achieve automated delivery and precise docking of connectors. Utility Model Content

[0014] Furthermore, the carrier includes a carrier plate for carrying the vehicle controller, and the carrier plate is provided with positioning blocks for positioning the vehicle controller.

[0015] Furthermore, the positioning mechanism includes a positioning baffle, which is located at the end of the roller assembly away from the test port. The positioning baffle is higher than the top of the power roller of the roller assembly. A positioning notch is provided on one side of the carrier plate. The positioning baffle and the positioning notch cooperate to block the side of the carrier plate.

[0016] Furthermore, the positioning mechanism also includes a positioning pin assembly. The carrier plate is provided with a positioning hole.

[0035] See appendix Figure 1 To be continued Figure 7 The figure shows a specific embodiment of the online testing device for automotive controllers provided by this utility model.

[0036] See appendix Figure 1 and attached Figure 3 The online testing equipment for automotive controllers includes:

[0037] Outer cover 1, with a test port 110 on the side of outer cover 1, and a platform 2 inside outer cover 1;

[0038] A roller conveyor assembly 3 is mounted on platform 2 and connected to test port 110. A carrier 4 is movably placed on roller conveyor assembly 3. The carrier 4 is used to carry and position the vehicle controller. Roller conveyor assembly 3 is used to transport the carrier 4 through test port 110 into outer cover 1.

[0039] A positioning mechanism 5 is located near the roller assembly 3. The positioning mechanism 5 is used to position the carrier 4 on the test position of the roller assembly 3.

[0040] The side-insertion assembly 6 and CCD assembly 7 are located on the side of the roller assembly 3. The CCD assembly 7 is used for visual positioning of the vehicle controller, and the side-insertion assembly 6 is used for side-insertion to the connector on the side of the vehicle controller for testing.

[0041] See appendix Figure 2 and attached Figure 3In the above embodiment, the outer cover 1 has a test port 110 and a human-machine interface 120 on two opposite sides, and maintenance windows on the other two opposite sides, so that the side insertion components 6 inside the outer cover 1 can be replaced through the maintenance windows to suit different test items. In this embodiment, the roller conveyor assembly 3 at the test port 110 is connected to the production line. The tester positions the car controller onto the carrier 4, and then places the carrier 4 onto the roller conveyor assembly 3. The roller conveyor assembly 3 transports the carrier 4 through the test port 110 into the outer casing 1 until it reaches the corresponding test position, at which point the roller conveyor assembly 3 stops transporting. Then, the positioning mechanism 5 positions and fixes the carrier 4 on the roller conveyor assembly 3. The CCD component 7 performs visual positioning of the car controller from the side of the roller conveyor assembly 3. The side insertion component 6 fine-tunes itself based on the visual positioning result of the CCD component 7 before being inserted into the connector on the side of the car controller for functional testing. Finally, the side insertion component 6 leaves the connector on the side of the car controller, the positioning mechanism 5 releases the positioning of the carrier 4, and the roller conveyor assembly 3 reverses its transport, conveying the carrier 4 through the test port 110 to outside the outer casing 1. The tester removes the car controller from the carrier 4, thus completing one test operation. In this embodiment, the roller conveyor assembly 3 has a CCD component 7 and a side insertion component 6 on both sides. This embodiment automates the entire process of vehicle controller operation, from transportation and precise positioning to automatic docking testing, significantly improving testing efficiency, avoiding positioning and docking errors caused by excessive manual intervention, and ensuring the reliability of test connections and the accuracy of results.

[0042] See appendix Figure 4 In the above embodiment, the roller conveyor assembly 3 includes two parallel side fixing plates 310 and a plurality of powered rollers 320 disposed between the two side fixing plates 310, as well as a geared motor 330 that is driveably connected to the powered rollers 320. In this embodiment, the roller conveyor assembly 3 realizes stable and controllable bidirectional transmission of the carrier 4 inside the equipment, which is convenient for automated assembly line integration.

[0043] See appendix Figure 4 In the above embodiment, a plurality of guide wheels 340 are arranged along the length of the side fixing plate 310 for guiding the carrier 4 when it comes into contact with the side of the carrier 4. In the embodiment, when the side of the carrier 4 contacts the guide wheel 340 during the transport of the carrier 4 by the power roller 320, the carrier 4 can automatically correct its deviation, so that the carrier 4 can move smoothly along the predetermined path and prevent deviation from causing positioning difficulties.

[0044] See appendix Figure 5In the above embodiment, the carrier 4 includes a carrier plate 410 for supporting the vehicle controller, and a positioning block 420 for positioning the vehicle controller is provided on the carrier plate 410. In the embodiment, the positioning block 420 is disposed at the four corners of the carrier plate 410 to achieve rapid and accurate pre-positioning of the vehicle controller on the carrier 4, so that when the positioning mechanism 5 positions the carrier 4, the vehicle controller is also in a synchronously positioned and fixed state. In the embodiment, handles 430 are also provided at both ends of the carrier plate 410 to facilitate the test personnel to move the carrier 4.

[0045] See appendix Figure 4 In the above embodiment, the positioning mechanism 5 includes a positioning baffle 510, which is located at the end of the roller assembly 3 away from the test port 110. The positioning baffle 510 is higher than the top of the power roller 320 of the roller assembly 3. A positioning notch 411 is provided on one side of the carrier plate 410. The positioning baffle 510 and the positioning notch 411 cooperate to block the side of the carrier plate 410. In the embodiment, when the carrier 4 is transported to the test position at the end of the roller assembly 3, away from the power roller 320 and guide wheel 340 on the roller assembly 3, the positioning baffle 510, which is higher than the top of the power roller 320, can perform coarse positioning by blocking the side of the carrier 4, ensuring that the carrier 4 reaches the predetermined test position.

[0046] See appendix Figure 4 In the above embodiment, the positioning mechanism 5 further includes a positioning pin assembly 520. The carrier plate 410 has positioning holes 412. When the carrier plate 410 is transported to the test position by the roller conveyor assembly 3, the positioning pin assembly 520 is lifted and inserted into the positioning holes 412. In this embodiment, when the carrier 4 reaches the test position at the end of the roller conveyor assembly 3, after the positioning baffle 510 performs coarse positioning by blocking the carrier 4 from the side, the positioning pin assembly 520 is lifted and inserted into the positioning holes 412 of the carrier plate 410, achieving fine positioning of the carrier 4. To ensure accurate positioning and reliable fixation, the platform 2 is provided with at least two positioning pin assemblies 520, and the carrier 4 is also simultaneously provided with at least two positioning holes 412, laying the foundation for subsequent high-precision visual positioning and automatic insertion / removal.

[0047] See appendix Figure 4 In the above embodiment, the positioning mechanism 5 further includes a height limiting block 530, which includes a vertical segment and a horizontal segment located at the top of the vertical segment. The vertical segment is fixed to the platform 2, and the horizontal segment is placed on the upper end of the carrier plate 410. In this embodiment, the horizontal and vertical segments of the height limiting block 530 form a figure-7 shape, which limits the height of the carrier 4 on the upper surface of its carrier plate 410 after the carrier 4 arrives at the test position, ensuring the stability of the carrier 4 in the vertical direction, preventing the carrier 4 from tilting or shaking during the test, and ensuring positioning reliability.

[0048] See appendix Figure 4In the above embodiment, a position sensor 8 is provided on the platform 2, and the position sensor 8 is located at the end of the roller conveyor assembly 3 away from the test port 110. In this embodiment, the position sensor 8 is located at the end of the roller conveyor assembly 3 to automatically detect whether the carrier 4 has been transported to the predetermined test position, which facilitates triggering subsequent positioning, visual positioning, and testing actions, improving the continuity and reliability of the automated process. In this embodiment, the position sensor 8 can be a fiber optic sensor. Optionally, a position sensor 8 can also be installed at the test port 110 to achieve a feeding detection effect.

[0049] See appendix Figure 6 In the above embodiment, the CCD component 7 includes a bracket 710, a horizontal slide 720 mounted on the bracket 710, and a vertical slide 730 mounted on the horizontal slide 720. A CCD module 740 is mounted on the vertical slide 730, and the CCD module 740 faces the side of the roller assembly 3. In this embodiment, the CCD module 740 achieves horizontal and vertical movement on the bracket 710 through the horizontal slide 720 and the vertical slide 730, enabling it to quickly and accurately move to the optimal viewing angle to visually locate the car controller on the side of the roller assembly 3 and obtain precise coordinate information to guide the side insertion.

[0050] See appendix Figure 7 In the above embodiments, the side-insertion assembly 6 includes a three-axis fine-tuning assembly 610 and a side-insertion connector 620 mounted on the three-axis fine-tuning assembly 610. In these embodiments, the three-axis fine-tuning assembly 610 enables precise position adjustment of the side-insertion connector 620 in the X / Y / Z directions, allowing it to be accurately aligned and reliably inserted into the connector on the side of the controller based on the visual positioning result of the CCD module 740, ensuring stable electrical connection and avoiding the risk of improper manual insertion. Specifically, after coarse positioning by the positioning baffle 510 and fine positioning by the positioning pin assembly 520, the CCD module 740 performs visual recognition, and the three-axis fine-tuning assembly 610 fine-tunes the side-insertion connector 620 before it is inserted into the vehicle controller for testing.

[0051] In summary, this embodiment provides an online testing device for automotive controllers. It achieves automated transport of the automotive controller by setting up a roller conveyor assembly 3, high-precision positioning by setting up a positioning mechanism 5 and a CCD assembly 7, and automated and reliable docking by setting up a side insertion assembly 6. It also achieves automatic correction of the carrier 4 by setting up guide wheels 340, coarse positioning of the carrier 4 by setting up a positioning baffle 510 in conjunction with a positioning notch 411, fine positioning of the carrier 4 by setting up a positioning pin assembly 520 in conjunction with a positioning hole 412, and automatic detection of whether the carrier 4 has been transported to the predetermined testing position by setting up a position sensor 8. This embodiment can achieve automated transport, high-precision positioning, and automatic and reliable docking of the automotive controller, improving the efficiency, stability, and reliability of the test results in the automotive controller testing process, while reducing labor costs and the risk of operational errors.
