Description

Technical Field

[0001] This invention relates to the field of electronic motherboard testing technology, and in particular to an automated testing device for electronic motherboards. Background Technology

[0002] With the rapid development of the electronics and information industry, the production volume and complexity of electronic motherboards, as core components of various computing devices and smart terminals, are constantly increasing. During the motherboard manufacturing process, rigorous performance and interface testing must be conducted to ensure product quality and stability.

[0003] Traditional motherboard testing relies heavily on manual operation or semi-automated equipment, resulting in low testing efficiency, long changeover and debugging times, high skill requirements for operators, and poor compatibility with different product models. Especially when facing the trend of multi-variety, small-batch production, existing equipment struggles to quickly adjust testing fixtures and interface positions, and frequent screw fixing and manual calibration severely restrict production line efficiency. Furthermore, when testing external interfaces, even minor alignment deviations can easily lead to interface damage or test failure. Therefore, the industry urgently needs a highly flexible automated testing device capable of rapid changeover, automated operation, and adaptive correction. We propose an automated testing device for electronic motherboards. Summary of the Invention

[0004] In order to overcome the technical problems existing in the prior art, the present invention provides an automated testing device for electronic motherboards.

[0005] To solve the above-mentioned technical problems, the present invention provides the following technical solution: including a base plate, and a lower detection mechanism, an upper detection mechanism and a cooperating detection mechanism are provided on the upper side of the base plate;

[0006] The upper detection mechanism includes a main mounting frame. A mating groove is provided on the upper side of the main mounting frame. A mating frame is movably installed inside the mating groove. A positioning groove is provided on the inner side of the mating frame. A network card mounting frame, a graphics card mounting frame, a fixed mounting frame, a memory module mounting frame, and a power supply mating assembly are respectively arranged inside the positioning groove. A constraint cover plate is snapped into the mating groove. A mounting hole and a limiting groove are provided on the lower side of the mating frame corresponding to the positions of the network card mounting frame, graphics card mounting frame, fixed mounting frame, and memory module mounting frame. A limiting block is snapped into the limiting groove. A magnetic block is fixedly provided on the side of the limiting block. A locking pin is through the lower side of the limiting block.

[0007] The mating detection mechanism includes a movable frame and a module frame. The module frame has a card block, a first connecting frame, a second connecting frame, an audio interface group, a display interface group, and a USB interface group on its side. The first connecting frame and the second connecting frame have mating holes on their sides. A constraint rod is movably installed inside the mating hole.

The first connecting frame and the second connecting frame have a first slot and a second slot on their sides, and a first trigger rod and a second trigger rod are provided on their sides.

[0008] Furthermore, the lower detection mechanism includes a sample motherboard, on the side of which are respectively provided a CPU slot, a memory slot, an external slot, a graphics card slot, a network card slot, a solid-state slot, and a power supply slot, forming a computer motherboard. A stage is movably provided on the upper side of the base plate, and the sample motherboard can be constrained and mounted on the upper side of the stage. Cylinders are symmetrically fixed on the upper side of the base plate corresponding to the two sides of the stage. A first slide rail is symmetrically fixedly connected to the lower side of the stage and is slidably mounted on the upper side of the base plate.

[0009] Furthermore, the main mounting bracket is located on the upper side of the platform. A first electric push rod is vertically fixed on the upper side of the base plate, and the output end of the first electric push rod is connected to the side of the main mounting bracket. A guide rod penetrating the main mounting bracket is vertically fixed on the upper side of the base plate. The network card mounting bracket, graphics card mounting bracket, fixed mounting bracket, and memory module mounting bracket are aluminum alloy brackets of different shapes made of aluminum alloy, and iron blocks are provided on both sides. The constraint cover plates are respectively attached to the upper side of the mating bracket, network card mounting bracket, graphics card mounting bracket, fixed mounting bracket, memory module mounting bracket, and power supply mating group for constraint.

[0010] Furthermore, the two sides of the constraint cover are fitted with locking groups, which are fixedly installed on the lower side of the main mounting bracket. The sides of the network card mounting bracket, graphics card mounting bracket, fixed mounting bracket, and memory module mounting bracket are respectively fixedly installed with network card detection boards, graphics card detection boards, solid-state detection groups, and memory detection boards. The network card detection boards, graphics card detection boards, solid-state detection groups, and memory detection boards are respectively engaged with the network card slot, graphics card slot, solid-state slot, and memory module slot. The upper side of the memory module mounting bracket is fitted with a CPU mounting bracket, and the side of the CPU mounting bracket is fixedly installed with a CPU detection group.

[0011] Furthermore, the limiting block extends into the positioning groove to constrain the lower side of the network card mounting bracket, graphics card mounting bracket, fixed mounting bracket, and memory module mounting bracket. The limiting block is a rectangular block with two protrusions on the side, and the magnetic block is a magnetic block that attracts the iron blocks at both ends of the network card mounting bracket, graphics card mounting bracket, fixed mounting bracket, and memory module mounting bracket. The locking pin thread is installed inside the mounting hole.

[0012] Furthermore, the movable frame is disposed on the side of the external slot, and a second electric push rod is fixedly connected to the side of the movable frame and the second electric push rod is fixedly disposed on the upper side of the base plate. A second slide rail is symmetrically fixedly disposed on the lower side of the movable frame and the second slide rail is slidably mounted on the upper side of the base plate. The module frame is fixedly mounted on the upper side of the movable frame by screws and fits snugly. The side of the module frame is provided with slots at equal intervals, and the card block is snapped into the inside of the slot.

The constraint rod is fixedly installed on the side of the card block. The diameter of the mating hole is larger than the diameter of the constraint rod. The support spring is movably sleeved on the side of the constraint rod. An elastic ring is movably sleeved on the side of the constraint rod and is movably installed on the wall of the mating hole.

[0014] Furthermore, the first slot and the second slot are adjacent and staggered, and the first trigger rod and the second trigger rod are respectively fixedly installed on the side of the module frame corresponding to the first slot and the second slot. The protrusions of the first trigger rod and the second trigger rod are staggered to correspond to the first slot and the second slot.

[0015] Compared with the prior art, the beneficial effects that this invention can achieve are:

[0016] 1. This invention achieves a high degree of automation and flexibility in electronic motherboard testing by setting up an upper testing mechanism and a cooperating testing mechanism, significantly improving testing efficiency and reducing reliance on manpower and operational difficulty. By setting a cooperating frame with a multi-functional positioning slot in the upper testing mechanism, and fixing important testing modules such as network card testing boards and graphics card testing boards on it through magnetic attraction and limiting blocks, the entire testing fixture forms a module that can be quickly disassembled and replaced as a whole. When changing product models, the operator only needs to move the locking group to remove the entire cooperating frame along with all the testing modules on it and replace it with another pre-assembled module, without the need for tedious screw disassembly and reassembly and position calibration of individual components.

[0017] 2. By setting up an upper detection mechanism, this invention, based on modular design, allows complex component positioning and installation work to be completed in advance by a specialist in an offline state and saved as a backup module. When changing production, on-site operators only need to perform simple pull-out and insertion actions to complete the entire changeover process without needing to master complex debugging and positioning knowledge. This allows ordinary workers who have undergone simple training to start operating the equipment, effectively solving the pain point of a shortage of professional testing personnel and reducing labor costs.

[0018] 3. This invention achieves adaptive correction of interface insertion by setting up a detection mechanism. Specifically, the detection mechanism has a floating connection structure. Through the floating structure composed of constraint rods, support springs, and elastic rings, the connector mounting bracket can make a slight floating displacement when subjected to lateral pressure. At the same time, by utilizing the cooperation of the staggered first trigger rods and second trigger rods with the first slots and second slots, the connector mounting bracket is guided to make adaptive adjustments to its left and right positions in stages. This structure can effectively compensate for the assembly tolerances and positioning errors between the device and the motherboard, ensuring that USB, audio, and other interfaces can be successfully connected even with slight misalignment during the insertion process. This avoids interface damage caused by forced insertion and removal, and improves the reliability and safety of the detection process.

[0019] 4. This invention integrates functions such as automated loading and unloading, automatic power supply, and automatic insertion and detection. Automatic loading and unloading is achieved by driving the platform to slide out with a cylinder, and the upper detection mechanism is driven to press down by an electric push rod to achieve synchronous insertion and detection of all onboard interfaces. With the automatic advancement of the side interface detection mechanism, the process from clamping to testing is automated, which greatly reduces manual intervention, meets the needs of large-scale and efficient production, and reduces on-site labor costs.

[0033] To make the technical means, creative features, and achieved objectives and effects of this invention easier to understand, the invention is further described below with reference to specific embodiments. However, the following embodiments are merely preferred embodiments of this invention and not all of them. Other embodiments obtained by those skilled in the art based on the embodiments described herein without creative effort are all within the protection scope of this invention. Unless otherwise specified, the experimental methods in the following embodiments are conventional methods, and the materials and reagents used in the following embodiments are commercially available unless otherwise specified.

[0034] Example: Figures 1 to 12As shown, an automated testing device for electronic motherboards includes a base plate 1, which is a rectangular plate made of fiberglass and can be used in conjunction with an assembly line for overall component movement. A lower testing mechanism 2, an upper testing mechanism 3, and a cooperating testing mechanism 4 are arranged on the upper side of the base plate 1. The lower testing mechanism 2 enables automated loading and unloading of the electronic motherboards to be tested, while the upper testing mechanism 3 enables automatic testing of the electronic motherboards. This allows for modular design of the testing components, with each component capable of quick replacement and position adjustment. Anyone can quickly operate the device with minimal training. The cooperating testing mechanism 4 also automatically tests the electronic motherboards to be tested, and can adaptively correct the position when the interface is plugged in.

[0035] like Figures 1 to 3 As shown, the lower testing mechanism 2 includes a sample motherboard 21, which is a common computer motherboard. The sample motherboard 21 has a CPU socket 211, a memory slot 212, an external slot 213, a graphics card slot 214, a network card slot 215, a solid-state drive slot 216, and a power supply slot 217 on its side. These components, when used with the sample motherboard 21, form a computer motherboard. All components are standard. A stage 22 is movably mounted on the upper side of the base plate 1. The sample motherboard 21 can be fixedly mounted on the upper side of the stage 22, allowing for automated loading and unloading with a subsequent robotic arm. The stages 22 are symmetrically positioned on the upper side of the base plate 1 corresponding to the two sides of the stage 22. A cylinder 23 is fixedly installed and is fixed to the side of the stage 22 via a connecting rectangular block. A first slide rail 24 is symmetrically fixedly connected to the lower side of the stage 22 and is slidably installed on the upper side of the base plate 1. The first slide rail 24 consists of a slider and a slide rail, which can constrain the stage 22. Specifically, the cylinder 23 pushes the stage 22, which is constrained by the first slide rail 24 and slides out. At this time, the entire sample motherboard 21 can be snapped into place on the upper side of the stage 22 by a robot arm. Then the cylinder 23 pulls the stage 22 back to its original position, and the detection position can be determined.

[0036] like Figures 3 to 8As shown, the upper detection mechanism 3 includes a main mounting frame 31 mounted on the upper side of the stage 22. The main mounting frame 31 is rectangular, and its side has an L-shaped groove corresponding to the sample main board 21. A mating groove 311 is provided on the upper side of the main mounting frame 31. The mating groove 311 is an L-shaped groove, forming a step shape on the upper side of the main mounting frame 31. A first electric push rod 32 is vertically fixed on the upper side of the base plate 1, corresponding to both sides of the main mounting frame 31, and the output end of the first electric push rod 32 is connected to the side of the main mounting frame 31. A guide rod 321 is symmetrically and vertically fixed on the upper side of the base plate 1, corresponding to the first electric push rod 32, and the guide rod 321 passes through the main mounting frame 31. The guide rod 321 is a cylindrical rod. The slot 311 houses a mating bracket 312, which is a hollow "L"-shaped bracket made of aluminum alloy. A positioning slot 313, a rectangular slot, can be provided inside the mating bracket 312 for quick positioning of subsequent components. Inside the positioning slot 313, a network card mounting bracket 341, a graphics card mounting bracket 351, a fixed mounting bracket 361, a memory module mounting bracket 371, and a power supply assembly 39 are respectively constrained. The network card mounting bracket 341, graphics card mounting bracket 351, fixed mounting bracket 361, and memory module mounting bracket 371 are aluminum alloy brackets of different shapes with iron blocks on both sides. The power supply assembly 39 consists of an aluminum alloy bracket and a power connector assembly. The device can be connected to the power supply slot 217 to supply power to various components of the sample motherboard 21. A constraint cover 33 is snapped into the mating slot 311 and is attached to the upper side of the mating frame 312, network card mounting frame 341, graphics card mounting frame 351, fixed mounting frame 361, memory module mounting frame 371, and power supply mating group 39 for constraint. Locking groups 331 are snapped into and fixedly installed on the lower side of the main mounting frame 31 on both sides of the constraint cover 33. The locking groups 331 adopt an existing rotating lever structure, and the lever can be snapped into the upper side of the constraint cover 33 for positioning and constraint. This applies to the network card mounting frame 341, graphics card mounting frame 351, and fixed mounting frame. The sides of the memory module mounting bracket 361 and the memory module mounting bracket 371 are respectively fixedly mounted with a network card detection board 34, a graphics card detection board 35, a solid-state detection group 36, and a memory detection board 37. The network card detection board 34, the graphics card detection board 35, the solid-state detection group 36, and the memory detection board 37 are respectively snapped into the network card slot 215, the graphics card slot 214, the solid-state slot 216, and the memory module slot 212 to run the detection program. A CPU mounting bracket 381 is snapped into the upper side of the memory module mounting bracket 371. The CPU mounting bracket 381 is a rectangular bracket. A CPU detection group 38 is fixedly mounted on the side of the CPU mounting bracket 381. The CPU detection group 38 can snap into the CPU slot 211 for detection.Specifically, depending on the motherboard, by moving the locking group 331 to open it, the network card detection plate 34 can be directly pulled out of the mating slot 311. At the same time, the CPU detection group 38 can be pulled out from the side of the memory module mounting bracket 371. Then, the network card mounting bracket 341, graphics card mounting bracket 351, fixed mounting bracket 361, and memory module mounting bracket 371, along with their side-mounted network card detection plates 34, graphics card detection plates 35, solid-state detection group 36, and memory detection plates 37, can be pulled out one by one. The mating bracket 312 can then be removed from the mating slot 311. Finally, a mating bracket 312 with different positioning slots 313 can be installed in the mating slot 311. 1. Inside, directly according to the position of the new positioning slot 313, constrain the installation of the network card mounting bracket 341, graphics card mounting bracket 351, fixed mounting bracket 361 and memory module mounting bracket 371, and quickly adjust the positions of the network card detection board 34, graphics card detection board 35, solid-state detection group 36 and memory detection board 37 without frequent screw fixing. After installing the power supply matching group 39 and CPU detection group 38 in the corresponding positions, the network card detection board 34 is snapped into the matching slot 311 to constrain the upper side of the matching bracket 312. It can be quickly constrained and fixed by the locking group 331 to quickly fix it. This effectively saves the changeover time of automated testing.

[0037] Furthermore, mounting holes 314 are provided on the lower side of the mating bracket 312 at the positions of the positioning grooves 313 corresponding to the network card mounting bracket 341, graphics card mounting bracket 351, fixed mounting bracket 361, and memory module mounting bracket 371. The mounting holes 314 are cylindrical threaded grooves. On the lower side of the mating bracket 312, corresponding to the positions of the network card detection plate 34, limit grooves 315 are symmetrically provided. The limit grooves 315 are rectangular grooves. Limit blocks 316 are engaged and installed inside the limit grooves 315, with a portion of the limit blocks 316 extending into the positions of the positioning grooves 313. The limit blocks 316 are rectangular blocks. This allows for the engagement of the network card mounting bracket 341, graphics card mounting bracket 351, and fixed mounting bracket. The lower sides of mounting brackets 361 and 371 are constrained. A limiting block 316 is a rectangular block with two protrusions on its side. A magnetic block 317 is fixedly installed through the side of the limiting block 316. The magnetic block 317 is a magnetic block that can attract the iron blocks at both ends of the network card mounting bracket 341, graphics card mounting bracket 351, fixed mounting bracket 361, and 371. A locking pin 318 is threaded through the lower side of the limiting block 316 and installed inside the mounting hole 314. The locking pin 318 is a countersunk screw. Specifically, the mounting hole 314 and the limiting block can be quickly drilled on the lower side of the existing mounting bracket 312 using a drill press. After operating slot 315, the limiting block 316 is positioned and installed inside the limiting slot 315. The limiting block 316 is then locked in place on the lower side of the mating bracket 312 by the locking pin 318. Similarly, after pulling the network card detection plate 34 out of the mating slot 311, when the mating bracket 312 is pulled out of the mating slot 311, the network card mounting bracket 341, graphics card mounting bracket 351, fixed mounting bracket 361, and memory module mounting bracket 371 can be more quickly removed by linking their side network card detection plate 34, graphics card detection plate 35, solid-state detection group 36, and memory detection plate 37. The corresponding network card mounting bracket 341 and graphics card mounting bracket 351 can then be removed more quickly by connecting them to the front end. Mounting bracket 351, fixed mounting bracket 361, and memory module mounting bracket 371 are magnetically attached and installed inside the positioning slot 313. Simultaneously, they are limited by the limiting block 316 and magnetically attached and fixed. This allows the mating bracket 312, along with the network card mounting bracket 341, graphics card mounting bracket 351, fixed mounting bracket 361, and memory module mounting bracket 371, to be quickly replaced inside the mating slot 311, further accelerating the changeover operation. Multiple sets of mating brackets 312 with positioning slots 313 at different positions can be set up, and corresponding components can be pre-installed inside their positioning slots 313 for backup. This allows for quick operation during changeover, enabling anyone to start operating without professional personnel.

[0038] like Figures 9 to 12As shown, the detection mechanism 4 includes a movable frame 41 disposed on the side of the external slot 213. The movable frame 41 is an "L"-shaped frame. A second electric push rod 42 is fixedly connected to the side of the movable frame 41 and is fixedly disposed on the upper side of the base plate 1. A second slide rail 421 is symmetrically fixedly disposed on the lower side of the movable frame 41 and is slidably mounted on the upper side of the base plate 1. The second slide rail 421 consists of a slider and a slide rail. A module frame 43 is attached to the upper side of the movable frame 41 and is locked to the side of the movable frame 41 by screws. The module frame 43 is an "L"-shaped frame. A slot 431 is equidistantly provided on the side of the module frame 43. 1 is a rectangular slot. A locking block 46, L-shaped, is installed inside the slot 431. A first connecting bracket 44 and a second connecting bracket 45 are respectively provided on the sides of the locking block 46. The first connecting bracket 44 and the second connecting bracket 45 are U-shaped brackets of different specifications. An audio interface group 441 and a display interface group 442 are respectively provided on the side of the first connecting bracket 44. A USB interface group 451 is respectively provided on the side of the second connecting bracket 45. The audio interface group 441, the display interface group 442, and the USB interface group 451 are fixedly installed on the sides of the first connecting bracket 44 and the second connecting bracket 45 with screws, and can be connected to various plugs on the side of the external slot 213. The second connecting bracket 44 and the side of the second connecting bracket 45 are symmetrically provided with through-holes 47 corresponding to the position of the locking block 46. The through-holes 47 are U-shaped cylindrical grooves. A constraint rod 471 is symmetrically and fixedly installed through the side of the locking block 46 and is movably disposed inside the through-holes 47. The constraint rod 471 is a T-shaped round rod. The diameter of the through-hole 47 is larger than the diameter of the constraint rod 471. A support spring 472 is movably sleeved on the side of the constraint rod 471 and is fixedly connected between the wall of the through-hole 47 and the side of the locking block 46. An elastic ring 473 is movably sleeved on the side of the constraint rod 471 and is movably installed on the wall of the through-hole 47. The inner side is a ring block of elastic material with a protrusion. A first slot 48 is opened on one side of the first connecting frame 44 and the second connecting frame 45, and a second slot 49 is opened on the other side of the first connecting frame 44 and the second connecting frame 45. The first slot 48 and the second slot 49 are adjacent and staggered. The first slot 48 and the second slot 49 are trapezoidal slots. A first trigger rod 481 and a second trigger rod 491 are fixedly installed on the side of the module frame 43 corresponding to the positions of the first slot 48 and the second slot 49, respectively. The first trigger rod 481 and the second trigger rod 491 are "L" shaped rectangular rods. The protrusions of the first trigger rod 481 and the second trigger rod 491 are staggered to correspond to the first slot 48 and the second slot 49.Specifically, removing the screws on the side of the module frame 43 allows for the replacement of the entire side component of the module frame 43. Additionally, the locking block 46 can be modularly installed and removed within the slot 431 to allow for the replacement of different first connecting brackets 44 and second connecting brackets 45 and their side components, adapting to different circuit boards. When the second electric push rod 42 pushes the module frame 43 so that the audio interface group 441, display interface group 442, and USB interface group 451 are engaged with the external slot 213, their displacements do not perfectly align. At this point, the first connecting bracket 44 and second connecting bracket 45 are compressed and pushed, the constraint rod 471 is constrained and guided within the mating hole 47, and the support spring 472 is deformed by compression. Firstly, the first trigger rod... When the first connecting bracket 44 or the second connecting bracket 45 is pressed against the side, the second trigger rod 491 is movably positioned inside the second slot 49, allowing the first connecting bracket 44 and the second connecting bracket 45 to shift to the right as a whole. Then, when the second trigger rod 491 is pressed against the side of the first connecting bracket 44 or the second connecting bracket 45, the first trigger rod 481 is movably positioned inside the first slot 48, allowing the first connecting bracket 44 and the second connecting bracket 45 to shift to the left as a whole. During this shift, the elastic ring 473 is compressed and deformed, ensuring that the audio interface group 441, the display interface group 442, and the USB interface group 451 are properly engaged with the external slot 213, preventing misalignment and failure to engage.

[0039] Working principle:

[0040] Before testing: First, at the assembly line station, multiple sets of mating frames 312 are placed. The network card mounting frame 341, graphics card mounting frame 351, fixed mounting frame 361, and memory module mounting frame 371, along with their side network card detection plates 34, graphics card detection plates 35, solid-state detection plates 36, and memory detection plates 37, are installed inside the corresponding positioning slots 313. At this time, the iron blocks at both ends of the network card mounting frame 341, graphics card mounting frame 351, fixed mounting frame 361, and memory module mounting frame 371 are attracted by the magnetic blocks 317 and constrained by the lower side of the limiting blocks 316. Together with the mating frames 312, they can form a complete spare part. Multiple sets of spare parts are placed at the station with clear markings for subsequent use with different models of sample motherboards 21.

[0041] The second step involves moving the locking assembly 331 to disengage it from the side of the constraint cover 33. Then, the network card detection plate 34 is pulled out of the mating slot 311. Simultaneously, the CPU detection assembly 38 can be pulled out of the side of the memory detection plate 37. The power supply mating assembly 39 remains in its original position. At this point, the mating bracket 312 can be pulled out of the mating slot 311, along with the network card mounting bracket 341, graphics card mounting bracket 351, fixed mounting bracket 361, and memory module mounting bracket 371 on the side of the mating bracket 312, and all their side components. The spare mating bracket 312 prepared at the front end is then installed inside the mating slot 311. The network card detection plate 34 is then locked inside the mating slot 311. Finally, the CPU detection assembly 38 is snapped into the side of the memory detection plate 37 to complete the replacement process. This replacement operation requires minimal manual intervention and only requires simple training for anyone to operate it.

[0042] During testing: First, the base plate 1 moves with the production line. When it reaches the loading position, the cylinder 23 pushes the stage 22 out of the upper position of the base plate 1. At this time, the sample main board 21 and its side parts can be placed on the upper position of the stage 22 by the robot arm and constrained. Then the cylinder 23 pulls the stage 22 back to its original position and testing can be carried out.

[0043] The second step involves connecting the upper end. The base plate 1 continues to move along the production line. At this time, the first electric push rod 32 pulls the main mounting bracket 31 downwards, allowing the power supply assembly 39 to engage with the power supply slot 217 to complete power supply. The network card detection board 34, graphics card detection board 35, solid-state detection group 36, memory detection board 37, and CPU detection group 38 are respectively engaged with the network card slot 215, graphics card slot 214, solid-state slot 216, memory slot 212, and CPU slot 211, allowing the detection program to run.

[0044] The third step involves side connection. Synchronously, the second electric push rod 42 pushes the movable frame 41, causing the module frame 43 to move closer to the external slot 213. At this point, the audio interface group 441, display interface group 442, and USB interface group 451 can engage with their corresponding external slot 213 interfaces, and the detection program runs. When there is a deviation between the audio interface group 441, display interface group 442, and USB interface group 451 and the external slot 213, the first connecting frame 44 and the second connecting frame 45 are pushed and compressed, deforming the support spring 472. Simultaneously, the first trigger rod 481 first compresses the first connecting frame 44 and the second connecting frame 45 to the left, and then the second trigger rod 491 compresses the first connecting frame 44 and the second connecting frame 45 to the left, ensuring that the audio interface group 441, display interface group 442, and USB interface group 451 can be aligned with the outside of the external slot 213. This allows for automated sample motherboard 21 operation except during production changes.

[0045] The module frame 43 can be replaced by removing the screws on the side of the module frame 43. The slot 431 on the side of the module frame 43 can be repositioned. Different audio interface groups 441, display interface groups 442 and USB interface groups 451 can be installed into the corresponding slot 431 through the card block 46 to complete the interface adaptation of the sample motherboard 21 of different specifications.

[0046] The embodiments of the present invention have been described in detail above with reference to the accompanying drawings. However, the present invention is not limited thereto. Various changes can be made within the scope of knowledge possessed by those skilled in the art without departing from the spirit of the present invention.
