Description

Technical Field

[0001] This invention relates to the field of graphics card testing technology, specifically to a graphics card data output interface synchronous testing system and testing equipment. Background Technology

[0002] In the field of modern computer hardware, the graphics card, as a core component of graphics processing, plays a crucial role in the performance of its data output interface. The graphics card's data output interface is responsible for transmitting processed image and video data to external devices such as monitors and projectors, directly impacting the user's visual experience. With the rapid development of technology, graphics card performance has continuously improved, and data output interfaces have become increasingly diversified, with HDMI and DP interfaces being widely used. To ensure the quality and performance of the graphics card's data output interface, an efficient and accurate synchronous testing system and equipment are needed. This not only ensures that the graphics card's performance indicators meet standards before leaving the factory but also allows for quick and accurate location of interface faults in after-sales repair scenarios. By synchronously testing the graphics card's data output interface, issues such as unstable signal transmission and compatibility problems can be detected in a timely manner, preventing problems such as abnormal image display and poor device connection caused by interface failures. This ensures the stable operation of the computer system, improves user satisfaction with graphics card products, and promotes the healthy development of the graphics card industry.

[0003] However, traditional graphics card data output interface testing technologies have many drawbacks. First, they are inefficient. Traditional methods mostly rely on manual operation. From connecting the testing equipment to reading the test data, each step needs to be completed manually. For graphics cards with multiple data output interfaces, the testing process is time-consuming and cannot meet the rapid testing needs of large-scale production, thus limiting production efficiency. Second, the testing accuracy is low. Manual testing is greatly affected by factors such as the experience and fatigue of the testers, which can easily lead to misjudgments. For example, when judging the stability of interface signal transmission, manual observation may not be able to accurately detect subtle signal fluctuations, thus missing potential interface problems. Third, they have poor compatibility. Traditional testing equipment is often designed for specific models or types of graphics card data output interfaces. It lacks sufficient adaptability to the new models and specifications of interfaces that are constantly emerging in the market, and cannot achieve universal testing of multiple interfaces, increasing testing costs and complexity. These shortcomings not only affect the production efficiency and product quality of graphics card manufacturers, but may also lead to defective graphics cards entering the market, causing a bad user experience and hindering the further development of the graphics card industry. To solve the above problems, we propose a synchronous testing system and testing equipment for graphics card data output interfaces. Summary of the Invention

The telescopic end of the telescopic rod is connected to the connector, and the inner side of the connector is connected to the detection pen. A moving mechanism is connected to the bottom of the fixed platform.

[0009] Preferably, the top of the fixing base is tilted at 45°, and the fixing inclined plate is tilted at 45° and perpendicular to the inclined surface of the fixing base.

[0010] Preferably, the bottom of the detection pen is perpendicular to the fixed platform, and the top of the detection pen is equipped with a circuit meter.

The movable threaded sleeve extends to the top of the placement plate, and the top of the movable threaded sleeve is connected to two sets of limiting plates. The inner side of the limiting plate is connected to a buckle.

[0014] A graphics card data output interface synchronization detection system includes:

[0015] The testing pen, a connector in the testing structure, is used to contact the graphics card data output interface to obtain electrical parameters;

[0016] The circuit connection board is located at the bottom of the mounting base and is equipped with HDMI and DP ports to enable electrical connection between the graphics card interface and the external detection circuit.

[0017] The first drive motor is installed on the left side of the mounting shell of the moving structure. It is used to drive the moving lead screw to rotate, thereby moving the placement board and graphics card horizontally on the fixed platform.

[0018] The second drive motor is connected to the front of the placement plate and is used to drive the bidirectional lead screw inside the placement plate to rotate, thereby adjusting the position of the graphics card on the placement plate.

[0019] The electric adjustment base, as part of the adjustment structure, is connected to the fixed base on the inside. It is used to precisely adjust its own height according to the feedback signal from the infrared detector head, thereby driving the detection structure to make fine adjustments in the vertical direction.

[0020] An infrared detector head is installed on the front of the electric adjustment base to monitor the position of the graphics card under test in real time and to send a position signal back to the electric adjustment base;

[0021] The processor coordinates the work of various components, controls the operation of drive motors, detects structural movements, and determines whether there are performance problems with the graphics card data output interface based on the electrical parameters obtained by the detection pen, and determines the type of problem if a problem exists.

[0022] The processor is used to compare the electrical parameters acquired by the detection pen with the pre-stored standard parameter models of various graphics card data output interfaces. Based on the comparison results, it determines whether there are performance problems with the graphics card data output interface and, if there are problems, determines the type of problem, such as unstable signal transmission or interface compatibility issues.

[0023] A method for synchronous detection of a graphics card data output interface, comprising:

[0024] S1. Initial Preparations:

[0025] The graphics card to be tested is placed on the placement plate and secured by the coordinated action of the movable threaded sleeve, the limiting plate, and the clips. The second drive motor is activated, which drives the bidirectional lead screw to rotate, causing the movable threaded sleeve to move and adjust the spacing of the limiting plate to accommodate graphics cards of different sizes. The clips further securely fix the graphics card, ensuring its stable position during the testing process.

[0026] S2. Coarse Position Adjustment:

[0027] The first drive motor is activated, which drives the moving lead screw to rotate, causing the movable sleeve to move along the lead screw within the mounting housing, thus moving the placement board and graphics card horizontally on the fixed platform. This process achieves initial adjustment of the graphics card's position, roughly aligning it with the area where the detection structure is located, preparing for subsequent precise adjustments.

[0028] S3. Precise adjustment of detection position:

[0029] The adjustment mechanism begins operation, with the infrared detector monitoring the graphics card's position in real time and sending signals back to the motorized adjustment base. Based on this feedback signal and with the assistance of the adjustment rod, the motorized adjustment base precisely adjusts its height, causing the detection structure on the fixed base and inclined plate to make minor vertical adjustments. This process ensures the detection structure is accurately aligned with the graphics card's data output interface, improving the precision of the detection position.

[0030] S4. Inspection and docking:

[0031] The telescopic rod in the detection structure extends according to the detection requirements, pushing the detection pen closer to the graphics card data output interface. The connector allows for minor adjustments to the position of the detection pen to better accommodate differences in interface shape and location. Due to the specific tilt angle design of the fixed ramp, the detection pen is accurately inserted into the interface at a suitable angle, with its bottom end perpendicular to the fixed platform to ensure vertical insertion.

[0032] S5. Electrical Connections and Testing:

[0033] After the test pen is inserted into the interface, it connects to the external testing circuit via the HDMI or DP port on the circuit board. For example, when testing the HDMI interface of a graphics card, the signal is transmitted through the test pen to the HDMI port and connected to the testing circuit to test the electrical performance of the graphics card interface, such as signal transmission stability and resolution support. The test data is displayed in real time through the circuit table on the top of the test pen.

[0034] S6. Multi-interface detection and position adjustment:

[0035] If the graphics card has multiple data output interfaces, after completing the test of one interface, the first drive motor is restarted to move the placement board and graphics card so that the next interface is aligned with the test structure. Steps 4 and 5 are repeated to achieve synchronous or step-by-step testing of multiple data output interfaces of the graphics card, ensuring comprehensive testing of the graphics card interface performance.

[0036] Compared with the prior art, the present invention provides a graphics card data output interface synchronization detection system and detection device, which has the following beneficial effects:

[0037] 1. Precise and efficient detection and positioning: This device monitors the graphics card position in real time through an infrared detector in the adjustment structure. The electric adjustment base automatically and precisely adjusts its height based on feedback signals. Combined with the horizontal position adjustment of the adjustment rod, it can quickly and accurately align the detection structure with the graphics card data output interface. This automated and precise positioning method greatly improves detection efficiency, reduces misjudgments caused by inaccurate positioning, and ensures that each detection is performed in the optimal position. Compared with the traditional manual positioning method, it greatly improves the accuracy and stability of detection, laying a solid foundation for obtaining reliable detection data.

[0038] 2. High compatibility and adaptability: This device, through the combination of a bidirectional lead screw, a movable sleeve, and a second drive motor inside the placement plate, can flexibly adjust the position of the graphics card on the placement plate according to the size of different graphics cards. Regardless of the width of the graphics card, the second drive motor can be activated to drive the bidirectional lead screw to rotate, causing the movable sleeve to move, thereby changing the distance between the limit plates and stabilizing the graphics card. At the same time, the adjustment structure can precisely adjust and connect the data output interface at different positions and angles, eliminating the need for frequent replacement of testing equipment or complex manual adjustments for different graphics cards. This significantly improves the versatility and efficiency of the equipment, while traditional equipment, due to limited compatibility, often cannot meet diverse testing needs.

[0039] 3. Comprehensive and Stable Testing Performance: This device, with its rich array of interfaces on the circuit board, such as HDMI and DP ports, can comprehensively test common data output interface types of graphics cards, covering the electrical performance testing of various interfaces. This ensures a holistic performance evaluation of the graphics card. Furthermore, the coordinated operation of the telescopic rod, connectors, and testing pen in the testing structure guarantees a stable connection to the graphics card interface during testing. The telescopic rod precisely controls the position of the testing pen, the connectors allow for fine-tuning of the pen to better adapt to interface differences, and the design of the testing pen's bottom being perpendicular to the fixed platform further enhances connection stability, effectively reducing the impact of external interference on the test results, and providing more comprehensive, stable, and reliable testing results.

[0040] 4. Flexible and convenient operation and mobility: This device solves these problems through the rational design of the moving mechanism and the overall structure. The moving mechanism consists of a mounting shell, a moving lead screw, a moving sleeve, and a first drive motor, which can easily move the placement plate and graphics card on the fixed platform. In actual testing, the position of the graphics card can be flexibly adjusted according to different testing processes and requirements to achieve rapid testing of different interfaces. Moreover, the entire device has a compact structure, and the moving mechanism gives the device a certain degree of mobility, making it easy to use in different sites or testing environments. Operators can easily move the device to a suitable position for testing, greatly improving the convenience of operation and the applicability of the equipment. In contrast, traditional devices are limited in their application in different scenarios due to their complex operation and inconvenient movement. Attached Figure Description

[0051] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0052] Please see Figure 1-9A graphics card data output interface synchronous detection system and detection equipment, including a fixed platform 1 and a detection mechanism 5, is characterized in that: two sets of adjustment structures 2 are connected to the left side of the top of the fixed platform 1, the adjustment structure 2 includes an adjustment rod 201, an electric adjustment seat 202, and an infrared detector 203. The electric adjustment seat 202 is connected to the outer side of the two sets of adjustment rods 201, the infrared detector 203 is connected to the front of the electric adjustment seat 202, the fixed seat 4 is connected to the inner side of the electric adjustment seat 202, the fixed inclined plate 401 is connected to the top of the fixed seat 4, and three sets of detection structures 5 are connected to the inner side of the fixed inclined plate 401. The three sets of detection structures 5 include a telescopic rod 501, a connector 502, and a detection pen 503. The telescopic end of the telescopic rod 501 is connected to the connector 502, the inner side of the connector 502 is connected to the detection pen 503, and a moving mechanism 6 is connected to the bottom of the fixed platform 1.

[0053] The top of the fixed platform 1 is provided with multiple sets of preset sockets 101, which penetrate the fixed platform 1.

[0054] Furthermore, the top of the fixed platform 1 is provided with a through groove, and the top of the movable sleeve 603 extends into the groove and to the top of the platform. The placement plate 7 is connected to the top of the movable sleeve 603. The groove provides a precise moving track for the movable sleeve 603, ensuring its smooth movement on the fixed platform 1, thereby ensuring that the placement plate 7 can accurately follow the movement, closely cooperating with the movement detection function of the entire device.

[0055] Furthermore, a circuit connection board 3 is connected to the bottom of the mounting base 4. An HDMI port 301 is connected to the left side of the right-side plane of the circuit connection board 3, and three sets of DP ports 302 are equidistantly connected to the right side of the right-side plane of the circuit connection board 3. The circuit connection board 3 connected to the bottom of the mounting base 4, along with its HDMI port 301 and DP port 302, works in conjunction with the detection structure 5 and the graphics card to be tested placed on the placement plate 7. The detection pen 503 connects to the graphics card's data output interface and then connects to an external detection circuit via the ports on the circuit connection board 3 to detect the graphics card's data output interface.

[0056] Furthermore, the top of the mounting base 4 is tilted at 45°, and the inclined plate 401 is tilted at 45° and perpendicular to the inclined surface of the mounting base 4. This tilt angle design is linked to the placement position of the graphics card on the detection structure 5 and the placement plate 7. The detection structure 5 is installed inside the inclined plate 401. When the graphics card is placed on the placement plate 7 and moves to the detection position, the angle between the detection pen 503 and the graphics card data output interface is optimized due to the tilt angle of the mounting base and the inclined plate.

[0057] Furthermore, the bottom of the testing pen 503 is perpendicular to the fixed platform 1, and a circuit meter is installed on the top of the testing pen 503. This arrangement is closely linked to the structure and process of the entire testing system. The testing pen 503 is installed inside the fixed inclined plate 401 via a telescopic rod 501 and a connector 502. When the placement plate 7 moves the graphics card to the testing position, the testing pen 503, perpendicular to the fixed platform 1, can accurately insert into the graphics card's data output interface, displaying the testing data through the top circuit meter.

[0058] Furthermore, the moving structure includes a mounting housing 601, a moving lead screw 602, a moving sleeve 603, and a first drive motor 604. The moving lead screw 602 is connected inside the mounting housing 601, and the moving sleeve 603 is connected to the outside of the moving lead screw 602 via a threaded structure. The first drive motor 604 is connected to the left side of the mounting housing 601. The moving structure, including the mounting housing 601, the moving lead screw 602, the moving sleeve 603, and the first drive motor 604, forms a linkage with the fixed platform 1, the placement plate 7, and other structures. The first drive motor 604 drives the moving lead screw 602 to rotate, causing the moving sleeve 603 to move along the lead screw inside the mounting housing 601, thereby moving the placement plate 7 on the fixed platform 1. This adjusts the position of the graphics card placed on the placement plate 7 to cooperate with the detection structure 5 for detection.

[0059] Furthermore, the top end of the movable sleeve 603 extends into the groove of the fixed platform 1 and to the top of the fixed platform 1. The output end of the first drive motor 604 extends into the interior of the mounting housing 601 and connects to one end of the movable lead screw 602. This connection method allows the first drive motor 604 to effectively drive the movable lead screw 602, thereby moving the movable sleeve 603 within the groove of the fixed platform 1, ultimately achieving the movement of the placement plate 7.

[0060] Furthermore, the top of the movable sleeve 603 is connected to a placement plate 7, and the interior of the placement plate 7 is connected to a bidirectional lead screw 701. Two sets of movable sleeves 702 are installed on the outside of the bidirectional lead screw 701 through a threaded structure. The front of the placement plate 7 is connected to a second drive motor 703, and the output end of the second drive motor 703 extends into the interior of the placement plate 7 and is fixedly connected to one end of the bidirectional lead screw 701. The placement plate 7 connected to the top of the movable sleeve 603, the bidirectional lead screw 701 inside, the movable sleeves 702, and the second drive motor 703 connected to the front of the placement plate 7 form a linkage with the graphics card placed on the placement plate 7. The second drive motor 703 drives the bidirectional lead screw 701 to rotate, causing two sets of movable sleeves 702 to move on the bidirectional lead screw 701, thereby adjusting the position of the graphics card placed on the placement plate 7. This works in conjunction with the detection structure 5 to complete the detection. The movable sleeves 702 extend to the top of the placement plate 7, and two sets of limiting plates 704 are connected to the top of the movable sleeves 702. The inner side of the limiting plates 704 is connected to the buckles 705. The movable sleeves 702 extend to the top of the placement plate 7, and the two sets of limiting plates 704 connected to the top and the buckles 705 on their inner sides are linked with the graphics card placed on the placement plate 7. When the movable sleeves 702 move on the bidirectional lead screw 701, they drive the limiting plates 704 and the buckles 705 to move, thereby fixing and adjusting the position of the graphics card on the placement plate 7, and working with the detection structure 5 to detect the data output interface of the graphics card.

[0061] A graphics card data output interface synchronization detection system includes:

[0062] The detection pen 503 and the connector 502 connected in the detection structure 5 are used to contact the graphics card data output interface to obtain electrical parameters.

[0063] The circuit connection board 3 is located at the bottom of the mounting base 4, and is equipped with HDMI port 301, DP port 302, etc., to realize the electrical connection between the graphics card interface and the external detection circuit.

[0064] The first drive motor 604 is installed on the left side of the mounting shell 601 of the movable structure 6 and is used to drive the movable lead screw 602 to rotate, thereby driving the placement plate 7 and the graphics card to move horizontally on the fixed platform 1.

[0065] The second drive motor 703 is connected to the front of the placement plate 7 and is used to drive the bidirectional lead screw 701 inside the placement plate 7 to rotate and adjust the position of the graphics card on the placement plate 7.

[0066] The electric adjustment base 202, as part of the adjustment structure 2, is connected to the fixed base 4 on its inner side. It is used to precisely adjust its own height according to the feedback signal of the infrared detector head 203, thereby driving the detection structure 5 to make fine adjustments in the vertical direction.

[0067] Infrared probe 203 is installed on the front of electric adjustment base 202 to monitor the position of the graphics card under test in real time and to feed back the position signal to electric adjustment base 202.

[0068] The processor coordinates the work of various components, controls the operation of the drive motor, detects structural movements, and determines whether there are performance problems with the graphics card data output interface based on the electrical parameters obtained by the detection pen 503, and determines the type of problem if a problem exists.

[0069] The processor is used to compare the electrical parameters obtained by the detection pen 503 with the pre-stored standard parameter models of various graphics card data output interfaces. Based on the comparison results, it determines whether there are performance problems with the graphics card data output interface and, if there are problems, determines the type of problem, such as unstable signal transmission or interface compatibility issues.

[0070] A method for synchronous detection of a graphics card data output interface, comprising:

[0071] S1. Initial Preparations:

[0072] The graphics card to be tested is placed on the placement plate 7 and secured by the coordinated action of the movable threaded sleeve 702, the limiting plate 704, and the clip 705. The second drive motor 703 is started, which drives the bidirectional lead screw 701 to rotate, causing the movable threaded sleeve 702 to move and adjust the spacing of the limiting plate 704 to accommodate graphics cards of different sizes. The clip 705 further secures the graphics card, ensuring its stable position during the testing process.

[0073] S2. Coarse Position Adjustment:

[0074] The first drive motor 604 is activated, which drives the moving lead screw 602 to rotate, causing the moving sleeve 603 to move along the lead screw within the mounting housing 601, thereby moving the placement plate 7 and the graphics card horizontally on the fixed platform 1. This process achieves preliminary adjustment of the graphics card's position, roughly aligning it with the area where the detection structure 5 is located, preparing for subsequent precise adjustments.

[0075] S3. Precise adjustment of detection position:

[0076] Adjustment structure 2 begins operation, with infrared detector 203 monitoring the graphics card's position in real time and feeding back the signal to the electric adjustment base 202. Based on the feedback signal and with the assistance of adjustment rod 201, the electric adjustment base 202 precisely adjusts its height, causing the detection structure 5 on the fixed base 4 and fixed inclined plate 401 to make minor adjustments in the vertical direction. This process ensures that the detection structure 5 is accurately aligned with the graphics card's data output interface, improving the accuracy of the detection position.

[0077] S4. Inspection and docking:

[0078] The telescopic rod 501 in the detection structure 5 extends according to the detection requirements, pushing the detection pen 503 closer to the graphics card data output interface. The connector 502 makes a small adjustment to the position of the detection pen 503 to better adapt to the differences in interface shape and position. Due to the specific tilt angle design of the fixed inclined plate 401, the detection pen 503 is accurately inserted into the interface at a suitable angle, and the bottom end is perpendicular to the fixed platform 1 to ensure the verticality of the insertion.

[0079] S5. Electrical Connections and Testing:

[0080] After the test pen 503 is inserted into the interface, it connects to the external testing circuit through the HDMI port 301 or DP port 302 on the circuit connection board 3. For example, when testing the HDMI interface of a graphics card, the signal is transmitted through the test pen 503 to the HDMI port 301 and connected to the testing circuit to test the electrical performance of the graphics card interface, such as signal transmission stability, resolution support, and other parameters. The test data is displayed in real time through the circuit table on the top of the test pen 503.

[0081] S6. Multi-interface detection and position adjustment:

[0082] If the graphics card has multiple data output interfaces, after completing the test of one interface, the first drive motor 604 is started again to move the placement plate 7 and the graphics card, so that the next interface is aligned with the test structure 5. Steps 4 and 5 are repeated to achieve synchronous or step-by-step testing of multiple data output interfaces of the graphics card, ensuring comprehensive testing of the graphics card interface performance.

[0083] Structural Description:

[0084] Fixed Platform: The fixed platform is the basic support structure of the graphics card data output interface synchronous detection system and detection equipment, providing a stable placement surface for the entire device. Its top space is rationally laid out, with an adjustment structure connected to the left side for installing and positioning adjustment components; multiple sets of preset sockets run through the fixed platform, which can be used for wiring, auxiliary fixing of other components, etc., enhancing the functionality and expandability of the equipment; the bottom connects to the moving mechanism, providing a connection base for the movement of the equipment and serving as a crucial support for the coordinated operation of all components of the entire detection equipment.

[0085] Pre-set sockets: Pre-set sockets are hole-like structures located on the top of the fixed platform and extending through it. Their function is to provide a channel for the rational arrangement of internal wiring, avoiding interference or safety hazards caused by exposed wiring. Simultaneously, they can also serve as auxiliary fixing points for other components. By inserting specific fasteners, relevant components can be securely installed on the fixed platform, increasing the flexibility and scalability of the equipment structure and meeting the needs of component installation and wiring planning under different testing requirements.

[0086] Adjustment Structure: The adjustment structure is an adjustable component installed on the top left side of the fixed platform, mainly composed of an adjustment rod, an electric adjustment base, and an infrared detector head. It plays a crucial role in position adjustment and detection position sensing within the entire detection system. Through coordinated control of its various components, it achieves precise docking between the detection structure and the data output interface of the graphics card under test, improving the accuracy and adaptability of the detection.

[0087] Adjustment rod: The adjustment rod is a support and position adjustment component in the adjustment structure, connecting the fixed platform and the electric adjustment base. Its outer side is connected to the electric adjustment base, allowing adjustment of the horizontal position of the electric adjustment base within a certain range. This provides support for the initial horizontal positioning of the detection structure, enabling the detection structure to be flexibly adjusted according to the positional differences of different graphics card data output interfaces, thus enhancing the equipment's adaptability to different graphics cards.

[0088] Electric Adjustment Mount: The electric adjustment mount is the core adjustment component of the adjustment structure. It connects to the fixed base on the inside and the infrared detector head on the front. Based on the adjustment rod, it can precisely control its own height, thereby driving the fixed base and the detection structure mounted on it to make fine adjustments in the vertical direction. By receiving signals from the infrared detector head, the electric adjustment mount can automatically adjust its height to ensure that the detection structure is accurately aligned with the graphics card's data output interface, improving the accuracy of the detection position.

[0096] Telescopic rod: The telescopic rod is a position adjustment component in the testing structure, with its telescopic end connected to a connector. During testing, the telescopic rod extends or retracts according to testing requirements, pushing the testing pen closer to or further away from the graphics card data output interface. This ensures the testing pen can be accurately inserted into the interface, achieving a good electrical connection and providing a foundation for acquiring testing data.

[0097] Connector: The connector is the part that connects the telescopic rod and the test pen, installed on the inside of the telescopic rod's telescopic end between the telescopic rod and the test pen. It not only serves a connecting function but also allows for minor adjustments to the test pen's position to better accommodate slight differences in the shape and location of the graphics card's data output interface, improving the accuracy of the test pen's connection to the interface and ensuring smooth testing.

[0098] Test pen: The test pen is the component in the testing structure that directly contacts the graphics card's data output interface and acquires test data. Its bottom is perpendicular to the fixed platform, and its top is equipped with a circuit meter. When the test pen is inserted into the graphics card's data output interface, it acquires various parameters of the interface through electrical connection and displays the test data in real time through the top circuit meter. It is a key component for testing the performance of the graphics card's data output interface.

[0099] The moving structure is a movable component installed at the bottom of the fixed platform, consisting of a mounting shell, a moving lead screw, a moving sleeve, and a first drive motor. It provides horizontal movement power for the graphics card to be tested, which is placed on the placement plate. By controlling the coordinated work of each component, it achieves precise movement of the placement plate and graphics card on the fixed platform, meeting the needs of different testing positions and improving testing efficiency and comprehensiveness.

[0100] Mounting Housing: The mounting housing is the outer shell component of the mobile structure, housing the moving lead screw and connecting to the first drive motor on the left side. It provides protection and mounting space for the moving lead screw and the first drive motor, while also serving as the connection carrier between the entire mobile structure and the bottom of the fixed platform, ensuring the mobile structure is securely mounted on the fixed platform and guaranteeing its stability during operation.

[0101] Moving lead screw: The moving lead screw is the transmission component in the moving structure. It is installed inside the mounting housing and connected to the moving sleeve on the outside via a threaded structure. One end is connected to the output end of the first drive motor. When the first drive motor starts, it drives the moving lead screw to rotate, causing the moving sleeve to move on its outside through threaded transmission. This provides power for the horizontal movement of the placement board and graphics card, achieving precise position adjustment.

[0102] The moving sleeve is a key component in the moving structure that enables horizontal movement. Its top extends into the groove of the fixed platform and to the top, connecting with the placement plate. Driven by the moving lead screw, it moves along the direction of the lead screw within the groove of the fixed platform, thereby causing the placement plate and the graphics card placed on it to move horizontally on the fixed platform, providing support for adjusting the detection position of the graphics card.

[0103] First drive motor: The first drive motor is the power source for the moving structure. It is installed on the left side of the mounting housing, and its output end extends into the housing and is fixedly connected to one end of the moving lead screw.

[0104] Placement Plate: The placement plate is a supporting component connected to the top of the moving sleeve. It internally connects to a bidirectional lead screw and externally to a second drive motor. It is used to place the graphics card under test, providing a stable placement surface. Simultaneously, through its internal structure and in coordination with the second drive motor, it can adjust the position of the graphics card on the placement plate according to different graphics card sizes, improving the device's compatibility with graphics cards of different specifications.

[0105] Bidirectional lead screw: The bidirectional lead screw is a transmission component inside the placement plate. Two sets of movable threaded sleeves are installed on its outer side via a threaded structure, and one end is fixedly connected to the output end of the second drive motor. When the second drive motor starts, it drives the bidirectional lead screw to rotate, causing the two sets of movable threaded sleeves to move along the thread direction on its outer side. This adjusts the distance between the two sets of movable threaded sleeves, thereby adjusting the position of the graphics card placed on the placement plate to accommodate graphics cards of different widths.

[0106] Movable Sleeve: The movable sleeve is a removable component installed on the outside of the bidirectional lead screw, extending to the top of the mounting plate, with its top end connected to a limiting plate. Driven by the bidirectional lead screw, the movable sleeve moves along the lead screw, thereby moving the limiting plate. By adjusting the position of the movable sleeve, the distance between the limiting plates can be changed to accommodate the fixing requirements of graphics cards of different sizes, ensuring the stability of the graphics card on the mounting plate.

[0107] Second drive motor: The second drive motor is the power component connected to the front of the mounting plate. Its output end extends into the mounting plate and is fixedly connected to one end of the bidirectional lead screw. It provides power for the rotation of the bidirectional lead screw.

Together with the clip, it firmly fixes the graphics card on the placement plate, ensuring the stability of the graphics card's position during testing.

[0109] Clips: Clips are fixing components installed inside the limiting plate, working in conjunction with the limiting plate. When the graphics card is placed on the placement plate, after adjusting the movable screw sleeve to make the limiting plate fit against both sides of the graphics card, the clips further securely fix the graphics card to the inside of the limiting plate, preventing the graphics card from shifting due to equipment vibration or minor displacement during the testing process. This ensures good contact between the graphics card and the testing structure during the testing process, improving the accuracy and reliability of the testing results.

[0110] Working principle;

[0111] Through the linkage of the fixed platform 1 and the adjustment structure 2, precise adjustment of the detection position and environment is achieved. The fixed platform 1, as the basic support structure of the entire device, provides a stable installation and operating platform for other components. The two sets of adjustment structures 2 connected to its top left side include an adjustment rod 201, an electric adjustment base 202, and an infrared detector 203. The adjustment rod 201 can adjust the position of the electric adjustment base 202 within a certain range according to actual detection needs, achieving preliminary positioning of the detection structure's horizontal position. The electric adjustment base 202 can precisely control its own height, thereby driving the fixed base 4 and the detection structure 5 to make fine adjustments in the vertical direction. The infrared detector 203 monitors the position information of the graphics card under test in real time. When the graphics card is placed on the placement plate 7 and moves with it, the infrared detector 203 senses the change in the graphics card's position and feeds the signal back to the electric adjustment base 202. The electric adjustment base 202 automatically adjusts its height based on feedback signals, ensuring that the detection structure 5 is accurately aligned with the data output interface of the graphics card. This ensures that the detection work is performed in the optimal position, improving detection accuracy. Through the linkage between the electric adjustment base 202, the fixed base 4, and the detection structure 5, the detection angle and position can be flexibly adjusted to adapt to the detection needs of different graphics cards. The inner side of the electric adjustment base 202 is connected to the fixed base 4, and three sets of detection structures 5 are installed on the inner side of the fixed inclined plate 401 at the top of the fixed base 4. When the electric adjustment base 202 is adjusted in position under the coordinated action of the adjustment rod 201 and the infrared detector 203, the fixed base 4 and the detection structure 5 move accordingly. Due to the specific tilt angle design of the fixed inclined plate 401 and the fixed base 4, the top of the fixed base 4 is tilted at 45°, and the fixed inclined plate 401 is tilted at 45° and perpendicular to the inclined surface of the fixed base 4. During the movement, the detection structure 5 can be aligned with the data output interface of the graphics card at a suitable angle. For example, to address the differences in the position and angle of the data output interfaces of different graphics card models, the electric adjustment seat 202 can be used to ensure a good connection between the testing pen 503 and the interface, avoiding poor contact or damage to the interface due to improper angles. This ensures smooth testing and improves the equipment's adaptability to different graphics cards. The coordinated operation of the telescopic rod 501, connector 502, and testing pen 503 in the testing structure 5 achieves accurate testing of the graphics card data output interface. The telescopic end of the telescopic rod 501 is connected to the connector 502, and the testing pen 503 is connected to the inside of the connector 502. During testing, the telescopic rod 501 extends and retracts according to testing requirements. When the testing structure 5 is aligned with the graphics card data output interface on the fixed inclined plate 401, the telescopic rod 501 extends, pushing the testing pen 503 closer to the interface. The design of the bottom of the testing pen 503 being perpendicular to the fixed platform 1 ensures accurate insertion into the interface.The test pen 503 has a circuit meter on its top. When the test pen 503 is inserted into the interface, the circuit meter displays the test data in real time. Through the electrical connection between the test pen 503 and the interface, various parameters of the graphics card data output interface are obtained, enabling accurate testing of the interface. Through the linkage between the fixed platform 1 and the moving mechanism 6, the position of the graphics card under test can be flexibly moved, achieving a comprehensive testing effect. The moving mechanism 6 connected to the bottom of the fixed platform 1 includes a mounting shell 601, a moving screw 602, a moving sleeve 603, and a first drive motor 604. The first drive motor 604 is installed on the left side of the mounting shell 601, and its output end extends into the mounting shell 601 and connects to one end of the moving screw 602. When the first drive motor 604 is started, it drives the moving screw 602 to rotate, and the moving sleeve 603 moves on the outside of the moving screw 602 through a threaded structure. The top of the moving sleeve 603 extends into the groove of the fixed platform 1 and to the top of the fixed platform 1, and the top of the moving sleeve 603 is connected to the placement plate 7. This allows the graphics card placed on the placement plate 7 to move horizontally on the fixed platform 1. By controlling the rotation direction and speed of the first drive motor 604, the position of the placement plate 7 and the graphics card can be precisely adjusted, allowing different data output interfaces of the graphics card to be aligned sequentially with the detection structure 5. This enables synchronous or step-by-step detection of multiple data output interfaces of the graphics card, improving detection efficiency and comprehensiveness. Through the linkage between the moving sleeve 603 in the moving mechanism 6 and the placement plate 7, the effect of stable support and precise movement of the graphics card under test is achieved. The top of the moving sleeve 603 is connected to the placement plate 7, providing stable support and movement power for the placement plate 7. When the moving sleeve 603 moves within the groove of the fixed platform 1 under the drive of the moving screw 602, the placement plate 7 moves smoothly accordingly. The stability of the placement plate 7 is crucial for the detection results; it ensures that the graphics card placed on it will not shake or shift during movement, guaranteeing that the detection pen 503 maintains good contact with the graphics card's data output interface at all times. Meanwhile, the precise movement control of the movable sleeve 603 on the placement plate 7 allows the graphics card to be accurately moved under the detection structure 5, achieving precise alignment at the detection position and providing strong support for the smooth progress of the detection work. Through the linkage between the placement plate 7 and its internal bidirectional lead screw 701, movable sleeves 702, and second drive motor 703, the placement position can be flexibly adjusted according to different graphics card sizes, improving equipment compatibility. The placement plate 7 is internally connected to the bidirectional lead screw 701, and two sets of movable sleeves 702 are installed on the outside of the bidirectional lead screw 701 via a threaded structure. The front of the placement plate 7 is connected to the second drive motor 703, and the output end of the second drive motor 703 extends into the placement plate 7 and is fixedly connected to one end of the bidirectional lead screw 701. When dealing with graphics cards of different sizes, the second drive motor 703 is activated, driving the bidirectional lead screw 701 to rotate. The rotation of the bidirectional lead screw 701 causes the two sets of movable sleeves 702 to move along the threaded direction on their outer sides, thereby changing the distance between the two sets of movable sleeves 702.The movable threaded sleeve 702 extends to the top of the placement plate 7. By adjusting the position of the movable threaded sleeve 702, it can accommodate the placement requirements of graphics cards of different widths, stably placing the graphics card on the placement plate 7. This improves the compatibility of the equipment with graphics cards of various specifications, ensuring that graphics cards of different sizes can be accurately positioned and fixed on the placement plate 7 for subsequent testing. Through the linkage of the movable threaded sleeve 702 with the limiting plate 704 and the clip 705, the graphics card under test is firmly fixed, ensuring the stability of the test. The top of the movable threaded sleeve 702 is connected to two sets of limiting plates 704, and the clip 705 is connected to the inner side of the limiting plate 704. When the movable threaded sleeve 702 is adjusted under the action of the bidirectional screw 701, the limiting plate 704 and the clip 705 move accordingly. After the graphics card is placed on the placement plate 7, by adjusting the position of the movable threaded sleeve 702, the limiting plate 704 is made to fit against the sides of the graphics card, and the clip 705 further securely fixes the graphics card to the inner side of the limiting plate 704. The limiting plate 704 restricts the lateral movement of the graphics card, preventing it from sliding left and right on the placement plate 7. The clip 705 provides stronger fixing force, preventing the graphics card from shifting due to equipment vibration or minor displacement during the testing process. This tight fixing method ensures the stability of the graphics card throughout the testing process, allowing the testing pen 503 to maintain good contact with the graphics card's data output interface, ensuring the accuracy and reliability of the test data and improving the quality of the test results. Through the linkage between the circuit connection plate 3, the testing structure 5, and the graphics card's data output interface, the electrical performance of the graphics card's data output interface is tested. The bottom of the mounting base 4 is connected to the circuit connection plate 3. The left side of the right-side plane of the circuit connection plate 3 is connected to the HDMI port 301, and the right side is equidistantly connected to three sets of DP ports 302. After the test pen 503 in the test structure 5 is inserted into the graphics card data output interface, it connects to the external test circuit through the corresponding port on the circuit connection board 3. When the test pen 503 is connected to the graphics card's HDMI interface, the signal is transmitted through the test pen 503 to the HDMI port 301 on the circuit connection board 3, and then connected to the external test circuit to test the electrical performance of the graphics card's HDMI interface, such as signal transmission stability and resolution support. The DP interface is tested in a similar manner. The circuit connection board 3 integrates test circuits for various common graphics card data output interfaces, enabling the device to perform unified testing on different types of interfaces, improving the integration and efficiency of the testing, while also ensuring the stability and accuracy of the test signal transmission, providing a foundation for a comprehensive and accurate evaluation of the graphics card's data output interface performance.
