Description

Technical Field

[0001] This application belongs to the field of intelligent driving testing technology, and specifically relates to a motherboard testing device and method for an intelligent driving controller for automobiles. Background Technology

[0002] With the continuous development of the automotive industry, the functions of the vehicle's electronic control unit (ECU), which serves as the brain of the vehicle, are constantly being deepened, playing a significant role in ensuring the normal and safe operation of the car. The controller of an intelligent driving vehicle is its "decision and execution center," responsible for receiving data from the perception layer, making decisions and planning, and driving the actuators to complete driving actions.

[0003] Currently, the testing of intelligent driving controller motherboards is carried out using specialized testing equipment. However, during the testing process, the testing head is always exposed to the outside, causing dust to accumulate on it. When too much dust accumulates, it affects the testing accuracy and requires frequent cleaning by staff, making it inconvenient to use. Summary of the Invention

[0004] To address the above problems, the present invention provides a motherboard testing device for an automotive intelligent driving controller, comprising: A conveying device for transporting the motherboard; A protective cover is fixed above the conveying device; The detection component is vertically and retractably disposed inside the protective cover, and includes a mounting plate and a plurality of detection heads disposed at the bottom of the mounting plate; A drive unit, mounted on the protective cover, is used to drive the detection component to move up and down; Two baffle mechanisms are respectively and vertically mounted on both sides of the protective cover along the conveying direction; and A mechanical linkage mechanism is connected between the detection component and the two baffle mechanisms; The mechanical linkage mechanism is configured to synchronously transmit the lifting motion generated by the driving device driving the detection component to the two baffle mechanisms, so that the detection component and the two baffle mechanisms perform synchronous lifting motion in the same direction.

[0005] Furthermore, the protective cover has vertical grooves on both sides, and the baffle mechanism includes a sliding member slidably disposed in the groove and a baffle connected to the sliding member.

[0006] Furthermore, the detection component also includes a connecting plate connected to the mounting plate; the mechanical linkage mechanism includes extensions fixed to the left and right sides of the connecting plate, and engaging portions fixed to the sliding parts of the two baffle mechanisms and cooperating with the extensions; the extensions and the engaging portions engage with each other to transmit motion.

[0007] Furthermore, the extension is a second rectangular plate, and the engaging part is a clamping plate with a slot, wherein the second rectangular plate is slidably inserted into the slot of the clamping plate.

[0008] Furthermore, the driving device includes a motor, a worm gear driven by the motor, a worm wheel meshing with the worm gear, and a threaded rod coaxially fixed and vertically arranged with the worm wheel; the threaded rod is connected to the detection component in a transmission manner.

[0009] Furthermore, the detection assembly also includes a connecting plate, and the threaded rod is threadedly connected to the connecting plate.

[0010] Furthermore, the device also includes a guide rod vertically fixed inside the protective cover, and the detection component is slidably connected to the guide rod.

[0011] Furthermore, the device also includes two side guards, which are located on the left and right sides of the mounting plate, respectively. Each side guard is connected to the mounting plate via a sliding pair, allowing the side guard to float vertically relative to the mounting plate. Even further, the sliding pair includes a vertical groove formed on the inner wall of the side guard and a slider fixed to the side of the mounting plate, the slider being slidably disposed within the groove.

[0012] Furthermore, the conveying device is provided with multiple sets of limiting blocks for positioning the motherboard. Furthermore, a flexible support plate is provided between several adjacent sets of limiting blocks, and the top surface of the support plate has a notch.

[0013] Furthermore, an observation window is provided on the side wall of the protective cover.

[0014] The present invention also provides a method for testing the motherboard of an automotive intelligent driving controller using the testing apparatus described in any of the above claims, comprising the following steps: The drive device is controlled to operate, driving the detection component and the two baffle mechanisms to descend synchronously, so that the baffle mechanisms close the two sides of the protective cover and the detection head contacts the motherboard for detection; After the test is completed, the drive device is controlled to run in reverse, driving the detection component and the two baffle mechanisms to rise synchronously, so that the baffle mechanisms open the two sides of the protective cover; Control the transmission device to transmit the motherboard.

[0015] Compared with the prior art, the present invention has the following advantages: This invention utilizes a mechanical linkage mechanism connecting the detection component and the baffle mechanism. This allows a single drive unit to simultaneously and in the same direction drive the baffle mechanisms on both sides to rise and fall while simultaneously raising and lowering the detection component. When the detection component descends for detection, the baffle mechanisms simultaneously descend to close the protective cover on both sides, forming a relatively sealed dustproof space. After detection, both mechanisms rise simultaneously to open the channel for mainboard transfer. This ingenious device achieves automatic coordination of the detection and dustproof sealing actions through simple mechanical linkage, perfectly matching the intermittent conveying rhythm of the production line. This significantly reduces the time the detection head is exposed to a dusty environment, effectively lowering the risk of dust contamination and maintenance frequency, and improving detection accuracy and automation level.

[0020] To make the objectives, technical solutions, and advantages of the embodiments of this application clearer, the technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0021] like Figures 1 to 7 As shown, the motherboard testing device for an intelligent driving controller of an automobile according to an embodiment of the present invention includes a base plate 1 and a conveying device 3. Several sets of support columns 2 are evenly installed on the front and rear side walls of the conveying device 3, and the support columns 2 are fixedly connected to the base plate 1. Several sets of limiting blocks 4 are evenly installed on the conveying device 3, and every four sets of limiting blocks 4 form a station for accommodating the motherboard 5. The motherboard 5 is placed inside each set of limiting blocks 4. A support plate 12 is installed between every four sets of limiting blocks 4. The support plate 12 is made of a soft material and can move with the conveying device 3. Its top surface has symmetrically opened recesses 13 for easy removal of the motherboard 5.

[0022] like Figure 2 and Figure 3 As shown, a protective cover 9 is installed at the upper center of the conveying device 3. Vertical grooves 7 are provided at both ends of the protective cover 9. Rectangular plates 6 (i.e., sliding elements) are slidably connected inside both sets of grooves 7. A baffle 8 is installed on the top of the rectangular plates 6, thus forming a liftable baffle mechanism. Rectangular plates 4 23 are installed on the inner walls of the front and rear ends of the conveying device 3 inside the protective cover 9. A driving device 11 is installed on the rectangular plate 4 23 at the front end of the protective cover 9, and a guide rod 20 is installed on the rectangular plate 4 23 at the rear end of the protective cover 9. The other end of the guide rod 20 is fixedly connected to the inner top of the protective cover 9.

[0023] like Figure 5As shown, the drive device 11 includes a motor 111, a threaded rod 112, a worm gear 113, and a worm wheel 114. The motor 111 is fixedly connected to the front outer wall of the protective cover 9, and its output end passes through and is rotatably connected to the interior of the protective cover 9. The worm gear 113 is mounted on the output end of the motor 111. The threaded rod 112 is rotatably connected to the top of the rectangular plate 23 located at the front end of the protective cover 9. The worm wheel 114 is mounted on the threaded rod 112 and meshes with the outer surface of the worm gear 113. In addition, the threaded rod 112 is threadedly connected to the mounting plate 16 through a connecting plate 19, thereby realizing the lifting and lowering of the mounting plate 16.

[0024] like Figure 4 As shown, a control device 10 is installed on the top of the protective cover 9. The control device 10 is electrically connected to a wire 21, which is located inside the protective cover 9. The other end of the wire 21 is electrically connected to a mounting plate 16. Several sets of detection heads 22 are evenly installed on the bottom of the mounting plate 16, and the detection heads 22 are aligned with the main board 5 below. Connecting plates 19 are fixedly installed at both ends of the mounting plate 16. One set of connecting plates 19 is slidably connected to the guide rod 20, and the other set of connecting plates 19 is threadedly connected to the threaded rod 112 of the drive device 11. Specifically, the connecting plate 19 has an internal threaded hole, and the threaded rod 112 is screwed into the internal threaded hole. Therefore, when the motor 111 drives the worm gear 114 and the threaded rod 112 to rotate through the worm gear 113, it can drive the connecting plate 19 and the entire detection assembly to rise and fall along the guide rod 20. In addition, the control device 10 (which can be a common PLC controller) can control the detection heads 22 to detect the main board 5, and can also control the motor 111 to start.

[0025] like Figure 5 and Figure 6 As shown, rectangular plates 17 (i.e., side guards) are also provided on the left and right sides of the mounting plate 16 as side guards. Vertical grooves 24 are provided at both the front and rear ends of the inner walls of the two sets of rectangular plates 17. Rectangular blocks 25, acting as sliders, are installed at the four corners of the mounting plate 16. The four sets of rectangular blocks 25 are slidably disposed within their respective grooves 24, thus forming a sliding pair. In the non-detection state, under the influence of gravity, the rectangular plates 17 rest on top of the rectangular blocks 25. When the mounting plate 16 descends, the rectangular plates 17 first contact the supporting plate 12 and stop. As the mounting plate 16 continues to descend, the rectangular blocks 25 slide relative to each other along the grooves 24, allowing the detection head 22 to extend and detect the main board 5. Simultaneously, the rectangular plates 17 cover the two edges of the main board 5, forming a secondary dustproof layer.

[0026] like Figure 7As shown, rectangular plates 15 (i.e., second rectangular plates) are fixedly installed as extensions on both the left and right sides of the connecting plate 19. Rectangular clamping plates 14, serving as engaging parts, are installed on the opposing sides of the two sets of rectangular plates 16. The rectangular plates 15 are inserted into the slots of the rectangular clamping plates 14, thus forming the mechanical linkage mechanism. When the connecting plate 19 rises and falls, the rectangular plates 16 and the baffle 8 are directly driven to rise and fall synchronously and in the same direction along the slide groove 7 through the insertion and engagement of the rectangular plates 15 and the rectangular clamping plates 14.

[0027] The rear end of the protective cover 9 has an observation window 18 for easy observation of the operation of the internal equipment.

[0028] The working principle of this invention is as follows: After the conveying device 3 delivers a motherboard 5 to the testing station below the protective cover 9 and pauses, the motor 111 of the control drive device 11 starts. The motor 111 drives the threaded rod 112 to rotate via the worm gear 113 and worm wheel 114, driving the connecting plate 19, mounting plate 16, and testing head 22 to descend as a whole. Simultaneously, through the linkage between the rectangular plate 2 15 and the rectangular clamping plate 14, the rectangular plates 1 6 and baffles 8 on both sides descend synchronously. The baffles 8 descend until they are close to the support plate 12, forming a relatively sealed space together with the protective cover 9. At the same time, the rectangular plate 3 17 first contacts the support plate 12, and then the testing head 22 contacts the motherboard 5 for testing. After the test is completed, the motor 111 reverses, driving the testing components and the baffle mechanism to rise synchronously. The baffles 8 rise to open the channels on both sides of the protective cover 9, and then the conveying device 3 starts, sending out the tested motherboard and sending in the next motherboard to be tested, repeating the cycle. The entire process achieves automatic and synchronous execution of detection and sealing / dustproof actions, effectively ensuring that the detection head 22 is in a closed environment during non-transfer periods, greatly reducing dust pollution.

[0029] Although this application has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features; and these modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the spirit and scope of the technical solutions of the embodiments of this application.
