Abstract
Description
Technical Field
[0001] This utility model relates to the field of domain controller testing technology, and specifically to a domain controller test line. Background Technology
[0002] With the rapid development of automotive intelligence, electrification, and connectivity, the importance of domain controllers as core components of automotive electronic systems is becoming increasingly prominent. Domain controllers integrate multiple functional modules and are responsible for processing and coordinating various complex automotive electronic systems, such as autonomous driving, smart cockpit, and power control. They can achieve centralized control and management of various vehicle subsystems, improving the vehicle's intelligence level and safety. Therefore, the performance and quality requirements for domain controllers are becoming increasingly stringent.
[0003] In existing technologies, the feeding of test lines is generally done manually or by feeding conveyors. Manual feeding is inefficient, while feeding conveyors lack an effective buffering mechanism, which leads to unstable material supply and affects testing efficiency. In addition, traditional test lines often lack a dedicated inspection process for pins, making it impossible to detect defects such as missing, worn, or broken pins in a timely manner. These hidden problems may cause malfunctions during product use, leading to abnormalities in automotive electronic systems and posing safety hazards to users. Utility Model Content
[0004] The purpose of this invention is to provide a domain controller test line that can achieve continuous and stable feeding, high detection reliability, and high detection efficiency.
[0005] A domain controller test line includes a test loading buffer, an FCT test device, and a finished pin detection device.
[0006] The test feeding buffer device includes a first machine, on which several parallel buffer return lines and a vision inspection mechanism are installed. The vision inspection mechanism is suspended above the buffer return lines and can move horizontally along the conveying direction perpendicular to the buffer return lines.
[0007] The FCT testing equipment includes a second machine, on which a loading and unloading conveying mechanism and several testing devices are installed. The loading and unloading conveying mechanism is used to move the domain controller on the buffer return line to the testing devices for functional testing, and to move the domain controller that has completed the test to the finished PIN pin testing equipment.
[0008] The finished PIN pin testing equipment includes a feeding conveyor line, a finished product handling device, a PIN pin testing device, and an unloading conveyor line. The finished product handling device is used to move the domain controllers on the feeding conveyor line to the PIN pin testing device, and to move the domain controllers that have been tested by the PIN pin testing device to the unloading conveyor line.
[0009] In the above scheme, the test loading buffer device is used to load and buffer domain controllers. The buffer return line can buffer multiple domain controllers. The vision inspection mechanism provides precise positioning for the FCT test equipment to pick up the materials. When all the domain controllers on a buffer return line are picked up, the vision inspection mechanism will move along the conveying direction perpendicular to the buffer return line to the adjacent buffer return line to achieve continuous and stable material supply. The loading and unloading conveying mechanism will transport the domain controllers to the test device for functional testing. It will also place the qualified domain controllers after the test on the loading conveyor line of the finished product PIN inspection device. The loading conveyor line will transport the domain controllers to the handling position of the finished product handling device. The finished product handling device will then transport the domain controllers to the PIN inspection device. The PIN inspection device is used to detect whether the PINs of the domain controllers are defective. After the inspection is completed, the qualified domain controllers will be transported to the unloading conveyor line for unloading. Performing functional testing on the domain controllers and then defect detection on the PINs ensures the reliability of the domain controllers and improves the level of product quality control. The entire test line has a high degree of automation and greatly improves the testing efficiency.
[0010] Furthermore, the buffer return line includes a support frame, a drive assembly, a rotating shaft, and a conveyor belt. The drive assembly is installed at one end of the support frame, and two rotating shafts are respectively installed at both ends of the support frame. One of the rotating shafts is connected to the drive assembly. The conveyor belt is wound around the rotating shaft, and multiple limiting plates are provided on the conveyor belt.
[0011] In the above scheme, the support frame is installed on the first machine platform to provide support. The drive component can drive one of the rotating shafts to rotate, and the conveyor belt can drive the other rotating shaft to rotate synchronously, thereby realizing the cyclic operation of the conveyor belt. The domain controller is placed on the conveyor belt. As the conveyor belt runs, the domain controller will move along the conveyor belt's transport direction. Multiple limit plates are set on the conveyor belt to position and limit the domain controllers. Multiple domain controllers can be buffered on the conveyor belt. During testing, the conveyor belt can sequentially transport the domain controllers to the transport position, ensuring the continuous operation of the test line and improving the overall testing efficiency.
[0012] Furthermore, the visual inspection mechanism includes a linear module, a connecting component, and an inspection camera. The linear module is mounted on the upper frame of the first machine tool, the connecting component is connected to the linear module, and the inspection camera is mounted on the connecting component.
[0013] In the above scheme, the linear module moves horizontally along the direction perpendicular to the buffer return line, which can drive the connected components and the detection camera to move synchronously. The detection camera can capture information such as the overall appearance, position and attitude of the domain controller, providing accurate positioning information for the subsequent loading and unloading mechanism, so as to accurately move the domain controller to the testing device. The detection camera has a large field of view, which can ensure that the entire domain controller is captured, providing accurate positioning reference for the loading and unloading mechanism, thereby improving the accuracy and reliability of functional testing.
[0014] Furthermore, the loading and unloading handling mechanism includes a handling robot, a rotating connecting bracket, and vacuum adsorption components. The rotating connecting bracket is connected to the drive end of the handling robot, and several vacuum adsorption components are installed on the rotating connecting bracket.
[0015] In the above scheme, the rotating connecting bracket is connected to the drive end of the handling robot. When the drive end of the handling robot moves, the rotating connecting bracket will move and rotate with it. The rotating connecting bracket can rotate at a certain angle, thereby adjusting the position and orientation of the vacuum adsorption component to meet the picking and placing requirements of the domain controller in different positions and postures, which greatly improves the flexibility and adaptability of handling.
[0016] Furthermore, the testing device includes a mounting base plate and a tooling mating mechanism and a tooling positioning mechanism mounted on the mounting base plate. The tooling positioning mechanism is used to fix the domain controller. The tooling mating mechanism includes a push cylinder, a probe mounting plate, and several probe assemblies. The probe mounting plate is connected to the push cylinder, and several probe assemblies are mounted on the probe mounting plate. The probe assemblies are used to insert into the interface on the domain controller for functional testing.
[0017] In the above scheme, the loading and unloading conveying mechanism places the domain controller on the tooling positioning mechanism. The tooling positioning mechanism can accurately fix the domain controller, ensuring the accuracy of its position and orientation. The push cylinder can push the probe mounting plate to move towards the domain controller. As the probe mounting plate moves, the probe assembly gradually approaches the interface on the domain controller. When the probe mounting plate moves to the appropriate position, the probe assembly will accurately insert into the corresponding interface on the domain controller. The test signals from the multimeter and other devices on the equipment are transmitted to the internal circuit of the domain controller through the probe assembly, realizing the functional testing of the domain controller.
[0018] Furthermore, the tooling positioning mechanism includes a positioning base plate, several sets of elastic positioning components, limiting components, and lateral clamping components. The elastic positioning components and limiting components are used to limit the displacement of the domain controller in the length direction, and the lateral clamping components are used to limit the displacement of the domain controller in the width direction.
[0019] In the above scheme, when the domain controller is placed on the positioning base plate, the domain controller will squeeze the elastic positioning component, and the elastic positioning component will generate a reverse elastic force. This elastic force acts on the domain controller and cooperates with the limiting component to keep the domain controller stable in the length direction and prevent it from sliding or shaking arbitrarily in the length direction. The lateral clamping component fixes the domain controller in the width direction to prevent it from being displaced in the width direction. This can reduce the test error caused by the change of the domain controller position, thereby improving the accuracy of the test results.
[0020] Furthermore, the finished product handling device includes a Y-axis module, an X-axis module, and a Z-axis module. One end of the Y-axis module is adjacent to the feeding conveyor line. The X-axis module is connected to the Y-axis module, and the Z-axis module is connected to the X-axis module. A second rotary material handling mechanism is installed on the Z-axis module.
[0021] In the above scheme, the Y-axis module can move the X-axis module and the Z-axis module to the top of the domain controller finished product on the feeding conveyor line. The Z-axis module can drive the second rotary picking mechanism to lift and lower to pick up the domain controller. After picking up the material, the X-axis module, Y-axis module, Z-axis module and the second rotary picking mechanism cooperate to place the finished product on the PIN needle detection device.
[0022] Furthermore, the second rotary material handling mechanism includes a rotary drive, a hollow rotary slide, a mounting bracket, and vacuum suction cups. The rotary drive is connected to the Z-axis module, the hollow rotary slide is connected to the output end of the rotary drive, the mounting bracket is connected to the hollow rotary slide, and several vacuum suction cups are adjustablely mounted on the mounting bracket.
[0023] In the above scheme, the Z-axis module can control the second rotary material handling mechanism to rise and fall to a suitable height. The output end of the rotary drive unit transmits power to the hollow rotary slide connected to it, which can drive the hollow rotary slide to rotate around its own central axis, thereby driving the mounting bracket and the vacuum suction cups and adsorbed domain controllers to rotate together. This allows for flexible picking and placing of domain controllers and adjustment of domain controllers to a suitable angle for subsequent testing. Since the vacuum suction cups are adjustablely mounted on the mounting bracket, the operator can pre-adjust the position and spacing of each vacuum suction cup according to factors such as the size, shape, and center of gravity of the domain controller to ensure stable and reliable gripping of the domain controller.
[0024] Furthermore, the PIN detection device includes a horizontal conveying assembly and a visual positioning assembly, a line scan detection assembly, and a power-on plugging assembly arranged sequentially along the conveying direction of the horizontal conveying assembly. The visual positioning assembly is used to take pictures and locate the domain controller. The line scan detection assembly is used to detect whether there are defects in the PIN pins on the domain controller. The power-on plugging assembly is used to perform power-on detection by plugging the PIN pins of the power-on interface.
[0025] In the above scheme, the horizontal conveying component sequentially transports the domain controller to the front of the vision positioning component, the line scan detection component, and the power-on mating component. The vision positioning component photographs and positions the PIN pins of the domain controller, providing accurate positioning data for the line scan detection component and the power-on mating component. The line scan detection component can determine whether the PIN pins of the domain controller are missing, worn, or broken, and locates and outputs the defects. After the power-on mating component plugs in the PIN pins, it applies a certain voltage or current to the PIN pins to detect their electrical performance. After the detection is completed, the finished product handling device transports the qualified domain controller to the unloading conveyor line.
[0026] Furthermore, the line scan detection assembly includes a support base, a rotation adjustment drive, a mounting plate, and a line scan camera. The rotation adjustment drive is mounted on the support base, the mounting plate is connected to the rotation adjustment drive, and the line scan assembly is mounted on the mounting plate.
[0027] In the above solution, the rotary adjustment drive can precisely control the rotation angle of the mounting plate, thereby adjusting the angle of the line scan camera mounted on the mounting plate so that it is aligned with the PIN pin to be detected, greatly improving the accuracy and precision of the detection.
[0028] This utility model discloses a domain controller assembly line that offers the advantages of continuous and stable feeding, high testing reliability, and high testing efficiency. A test feeding buffer device is used to buffer domain controllers, and the buffer return line can buffer multiple domain controllers. A vision inspection mechanism provides precise positioning for the FCT testing equipment to pick up the controllers. Once all domain controllers on one buffer return line have been picked up, the vision inspection mechanism moves along a direction perpendicular to the buffer return line to an adjacent buffer return line, achieving continuous and stable feeding.
[0029] The loading and unloading conveying mechanism transports the domain controllers to the testing device for functional testing. After the test, the qualified domain controllers are placed on the loading conveyor line of the finished product PIN inspection equipment. The loading conveyor line transports the domain controllers to the handling position of the finished product handling device, which then transports them to the PIN inspection device. The PIN inspection device is used to detect whether the PINs of the domain controllers are defective. After the inspection, the qualified domain controllers are transported to the unloading conveyor line for unloading. Performing functional testing on the domain controllers and then defect detection on the PINs ensures the reliability of the domain controllers, improves the level of product quality control, and the entire testing line has a high degree of automation.

[0041] The present invention provides a domain controller test line in further detail below with reference to specific embodiments and accompanying drawings.
[0042] like Figure 1 As shown, in a preferred embodiment, a domain controller test line of the present invention includes a test loading buffer device 100, an FCT test device 200, and a finished PIN pin detection device 300. The test loading buffer device 100 includes a first machine base 1, on which a plurality of parallel buffer return lines 2 and a vision inspection mechanism 3 are installed. The vision inspection mechanism 3 is suspended above the buffer return lines 2 and can move horizontally along the conveying direction perpendicular to the buffer return lines 2.
[0043] The FCT testing equipment 200 includes a second machine base 4, on which a loading and unloading conveying mechanism 5 and several testing devices 6 are installed. The loading and unloading conveying mechanism 5 is used to move the domain controller on the buffer return line 2 to the testing device 6 for functional testing, and to move the domain controller that has completed the test to the finished PIN pin testing equipment 300.
[0044] The finished PIN pin testing equipment 300 includes a feeding conveyor line 7, a finished product handling device 8, a PIN pin testing device 9, and an unloading conveyor line 10. The finished product handling device 8 is used to transport the domain controllers on the feeding conveyor line 7 to the PIN pin testing device 9, and to transport the domain controllers that have been tested by the PIN pin testing device 9 to the unloading conveyor line 10.
[0045] The test feeding buffer device 100 is used to feed and buffer domain controllers. The buffer return line 2 can buffer multiple domain controllers. The vision inspection mechanism 3 provides precise positioning for the FCT test device 200 to pick up the material. When all the domain controllers on a buffer return line 2 have been picked up, the vision inspection mechanism 3 will move along the conveying direction perpendicular to the buffer return line 2 to the adjacent buffer return line 2 to achieve continuous and stable material supply.
[0046] The loading and unloading conveying mechanism 5 transports the domain controller to the testing device 6 for functional testing. After the test, the qualified domain controller is placed on the loading conveyor line 7 of the finished product PIN inspection equipment 300. The loading conveyor line 7 transports the domain controller to the handling position of the finished product handling device 8. The finished product handling device 8 then transports the domain controller to the PIN inspection device 9. The PIN inspection device 9 is used to detect whether the PINs of the domain controller are defective. After the inspection is completed, the qualified domain controller is transported to the unloading conveyor line 10 for unloading via the finished product handling device 8. Performing functional testing on the domain controller and then defect detection on the PINs ensures the reliability of the domain controller performance, improves the product quality control level, and the entire testing line has a high degree of automation, which greatly improves the testing efficiency.
[0047] like Figure 2 As shown, in some embodiments, the buffer return line 2 includes a support frame 21, a drive assembly 22, a rotating shaft 23, and a conveyor belt 24. The drive assembly 22 is installed at one end of the support frame 21, and two rotating shafts 23 are respectively installed at both ends of the support frame 21. One of the rotating shafts 23 is connected to the drive assembly 22. The conveyor belt 24 is wound around the rotating shaft 23 and has multiple limiting plates 25. The support frame 21 is installed on the first machine base 1 to provide support. The drive assembly 22 can drive one of the rotating shafts 23 to rotate, and the conveyor belt 24 can drive the other rotating shaft 23 to rotate synchronously, thereby realizing the cyclic operation of the conveyor belt 24. The domain controller is placed on the conveyor belt 24. As the conveyor belt 24 rotates, the domain controller will move along the conveying direction of the conveyor belt 24. The multiple limiting plates 25 on the conveyor belt 24 are used to position and limit the domain controllers. Multiple domain controllers can be buffered on the conveyor belt 24. During testing, the conveyor belt 24 can sequentially transport the domain controllers to the transport position to ensure the continuous operation of the test line and improve the overall testing efficiency.
[0048] In this embodiment, both ends of the conveyor belt 24 have position sensors to sense the domain controller. The sensors can be mounted on the support frame 21. The specific loading process of the buffer return line 2 is as follows: a person or robot puts material on one end of the conveyor belt 24. When the sensor detects the domain controller, the conveyor belt 24 will move forward one product position. Then, material is put on until the conveyor belt 24 is full. At this time, the position sensors at both ends will detect that there are products. After one conveyor belt 24 is full, another conveyor belt 24 is put on until all conveyor belts 24 are full. During the material handling process, after the loading and unloading mechanism 5 removes a product, the conveyor belt 24 will move forward one product position to ensure the continuity of material handling. When the products on one conveyor belt 24 are all removed, material can continue to be put on the conveyor belt 24. Material handling and material loading do not interfere with each other and can be carried out simultaneously, which greatly improves the continuity of product loading.
[0049] like Figure 3 As shown, in some embodiments, the visual inspection mechanism 3 includes a linear module 31, a connecting component 32, and an inspection camera 33. The linear module 31 is mounted on the upper frame 101 of the first machine tool 1, the connecting component 32 is connected to the linear module 31, and the inspection camera 33 is mounted on the connecting component 32. The linear module 31 moves horizontally along a direction perpendicular to the feed direction of the buffer return line 2, which can drive the connected component 32 and the inspection camera 33 to move synchronously. The inspection camera 33 can capture information such as the overall appearance, position, and attitude of the domain controller, providing accurate positioning information for the subsequent loading and unloading mechanism 5, so as to accurately transport the domain controller to the testing device 6. The inspection camera 33 can be a panoramic camera, which has a large field of view and can ensure that the entire domain controller is captured, providing accurate positioning reference for the loading and unloading mechanism 5, thereby improving the accuracy and reliability of functional testing.
[0050] like Figure 4 As shown, in some embodiments, the loading and unloading conveying mechanism 5 includes a conveying robot 51, a rotating connecting bracket 52, and vacuum suction components 53. The rotating connecting bracket 52 is connected to the drive end of the conveying robot 51, and several vacuum suction components 53 are mounted on the rotating connecting bracket 52. Since the rotating connecting bracket 52 is connected to the drive end of the conveying robot 51, when the drive end of the conveying robot 51 moves, the rotating connecting bracket 52 moves and rotates along with it. The rotating connecting bracket 52 can rotate at a certain angle, thereby adjusting the position and orientation of the vacuum suction components 53 to adapt to the picking and placing requirements of domain controllers in different positions and postures, greatly improving the flexibility and adaptability of the conveying process.
[0051] like Figure 5As shown, in some embodiments, the test device 6 includes a mounting base plate 61 and a tooling mating mechanism 62 and a tooling positioning mechanism 63 mounted on the mounting base plate 61. The tooling positioning mechanism 63 is used to fix the domain controller. The tooling mating mechanism 62 includes a push cylinder 621, a probe mounting plate 933622 and a plurality of probe assemblies 623. The probe mounting plate 933622 is connected to the push cylinder 621. The plurality of probe assemblies 623 are mounted on the probe mounting plate 933622. The probe assemblies 623 are used to insert into the interface on the domain controller for functional testing. The loading and unloading conveying mechanism 5 places the domain controller on the tooling positioning mechanism 63. The tooling positioning mechanism 63 can accurately fix the domain controller, ensuring the accuracy of its position and orientation. The push cylinder 621 can push the probe mounting plate 933622 towards the domain controller. As the probe mounting plate 933622 moves, the probe assembly 623 gradually approaches the interface on the domain controller. When the probe mounting plate 933622 moves to the appropriate position, the probe assembly 623 will accurately insert into the corresponding interface on the domain controller. The test signals from the multimeter and other devices on the equipment are transmitted to the internal circuit of the domain controller through the probe assembly 623 to realize the functional testing of the domain controller.
[0052] It should be noted that the principle of using probe component 623 to perform functional testing with multimeters and other devices is basically the same as that of existing FCT testing technology, and will not be described in detail here.
[0053] like Figure 6 As shown, in some embodiments, the tooling positioning mechanism 63 includes a positioning base plate 631, several sets of elastic positioning components 632, limiting components 633, and a lateral clamping component 634. The elastic positioning components 632 and limiting components 633 are used to limit the displacement of the domain controller in the length direction, and the lateral clamping component 634 is used to limit the displacement of the domain controller in the width direction. When the domain controller is placed on the positioning base plate 631, the domain controller will squeeze the elastic positioning components 632, and the elastic positioning components 632 will generate a reverse elastic force. This elastic force acts on the domain controller and cooperates with the limiting components 633 to keep the domain controller stable in the length direction and prevent it from sliding or shaking arbitrarily in the length direction. The lateral clamping component 634 fixes the domain controller in the width direction and prevents it from displacing in the width direction. This can reduce the test error caused by the change of the domain controller position, thereby improving the accuracy of the test results.
[0054] In this embodiment, the elastic positioning component 632 includes a positioning block 6321, a linear guide rail 6322, a sliding connecting block 6323, and a spring 6324. The positioning block 6321 is connected to the sliding connecting block 6323, and the sliding connecting block 6323 is slidably disposed on the linear guide rail 6322. The linear guide rail 6322 is mounted on the positioning base plate 631. At the same time, the sliding connecting block 6323 is connected to the spring 6324, and one end of the spring 6324 is fixed on the positioning base plate 631. When the domain controller is placed, the positioning block 6321 is squeezed, and the spring 6324 is compressed, so that the domain controller can be placed between the limiting component 633 and the elastic positioning component 632.
[0055] In this embodiment, the lateral clamping component 634 can be a clamping plate driven by a cylinder. The cylinder pushes the clamping plate closer to the domain controller, and the clamping plate tightly clamps both sides of the domain controller.
[0056] like Figure 7 As shown, in some embodiments, the finished product handling device 8 includes a Y-axis module 81, an X-axis module 82, and a Z-axis module 83. One end of the Y-axis module 81 is adjacent to the feeding conveyor line 7. The X-axis module 82 is connected to the Y-axis module 81, and the Z-axis module 83 is connected to the X-axis module 82. A second rotary picking mechanism 84 is installed on the Z-axis module 83. The Y-axis module 81 can move the X-axis module 82 and the Z-axis module 83 to a position above the finished domain controller on the feeding conveyor line 7. The Z-axis module 83 can drive the second rotary picking mechanism 84 to lift and lower to pick up the domain controller. After picking up the material, the X-axis module 82, the Y-axis module 81, the Z-axis module 83, and the second rotary picking mechanism 84 cooperate to place the finished product on the PIN needle detection device 9.
[0057] like Figure 7 As shown, in some embodiments, the second rotary material handling mechanism 84 includes a rotary drive 841, a hollow rotary slide 842, a mounting bracket 843, and vacuum suction cups 844. The rotary drive 841 is connected to the Z-axis module 83, the hollow rotary slide is connected to the output end of the rotary drive 841, and the mounting bracket 843 is connected to the hollow rotary slide 842. Several vacuum suction cups 844 are adjustablely mounted on the mounting bracket 843. The Z-axis module 83 can control the second rotary material handling mechanism 84 to rise and fall to a suitable height. The output end of the rotary drive 841 transmits power to the hollow rotary slide 842 connected to it, which drives the hollow rotary slide 842 to rotate around its own central axis. This causes the mounting bracket 843, the vacuum suction cups 844 mounted on it, and the adsorbed domain controller to rotate together, allowing for flexible picking and placing of the domain controller and adjustment of the domain controller to a suitable angle for subsequent detection.
[0058] Since the vacuum suction cups 844 are adjustablely mounted on the mounting bracket 843, the operator can pre-adjust the position and spacing of each vacuum suction cup 844 according to factors such as the size, shape and center of gravity of the domain controller to ensure stable and reliable gripping of the domain controller.
[0059] like Figure 8 As shown, in some embodiments, the PIN detection device 9 includes a horizontal conveying assembly 91 and a visual positioning assembly 92, a line scan detection assembly 93, and a power-on plugging assembly 94 arranged sequentially along the conveying direction of the horizontal conveying assembly 91. The visual positioning assembly 92 is used to take pictures and locate the domain controller, the line scan detection assembly 93 is used to detect whether there are defects in the PIN pins on the domain controller, and the power-on plugging assembly 94 is used to perform power-on detection by plugging the PIN pins of the power-on interface. The horizontal conveyor assembly 91 sequentially transports the domain controller to the front of the vision positioning assembly 92, the line scan detection assembly 93, and the power-on mating assembly 94. The vision positioning assembly 92 photographs and positions the PIN pins of the domain controller, providing accurate positioning data for the line scan detection assembly 93 and the power-on mating assembly 94. The line scan detection assembly 93 can determine whether the PIN pins of the domain controller are missing, worn, or broken, and locates and outputs the defects. After the power-on mating assembly 94 connects to the PIN pins, it applies a certain voltage or current to the PIN pins to test their electrical performance. After the test is completed, the finished product handling device 8 transports the qualified domain controller to the unloading conveyor line 10.
[0060] like Figure 8 As shown, in some embodiments, the line scan detection assembly 93 includes a support base 931, a rotation adjustment drive 932, a mounting plate 933, and a line scan camera 934. The rotation adjustment drive 932 is mounted on the support base 931, and the mounting plate 933 is kinetically connected to the rotation adjustment drive 932. The line scan assembly is mounted on the mounting plate 933. The rotation adjustment drive 932 can precisely control the rotation angle of the mounting plate 933, thereby adjusting the angle of the line scan camera 934 mounted on the mounting plate 933 so that it is aligned with the PIN pin to be detected. The line scan camera 934, being a 3D line scan camera, greatly improves the accuracy and precision of detection.
[0061] In the above embodiments, the specific steps and procedures for the line scan detection component 93 to detect the PIN pins are as follows:
[0062] Step 1, Laser Irradiation: The laser emits a laser beam that irradiates the surface of the PIN pin, creating speckle patterns.
[0063] Step 2, Image Capture: The camera captures speckle images.
[0064] Step 3: Data Processing: Use computer vision algorithms to process and calculate the image to obtain the three-dimensional coordinate information of the needle.
[0065] Fourth, defect detection: By calculating the height information of the PIN pins, it is determined whether they are missing, worn or broken, and the defects are located and output.
[0066] This invention relates to the working principle and process of a domain controller test line. Multiple domain controllers are cached on a cache return line 2. A vision inspection mechanism 3 suspended above the cache return line 2 takes pictures and positions the domain controllers, providing accurate position information for the subsequent material handling by the FCT testing equipment 200. Based on the positioning information provided by the vision inspection mechanism 3, the loading and unloading conveying mechanism 5 transports the domain controllers on the cache return line 2 to the testing device 6 on the second machine 4. The testing device 6 performs functional tests on the domain controllers. After the tests are completed, the loading and unloading conveying mechanism 5 transports the qualified domain controllers to the loading conveyor line 7 of the finished product PIN pin testing equipment 300. The loading conveyor line 7 transports the domain controllers to an operable position of the finished product handling device 8. Then, the finished product handling device 8 transports the domain controllers to the PIN pin testing device 9. The PIN pin testing device 9 performs defect detection on the PIN pins of the domain controllers. After the detection is qualified, the finished product handling device 8 transports the domain controllers to the unloading conveyor line 10, completing the entire testing process.
