Description

Technical Field

[0001] This application relates to the field of motherboard testing, and more specifically, to a motherboard FCT testing device. Background Technology

[0002] FCT, also known as functional testing, refers to a testing method that uses FCT testing equipment to provide a simulated operating environment for the test target board, causing it to work in various design states, thereby obtaining parameters for each state to verify the functionality. Server motherboards and PC motherboards also need to be tested using FCT testing equipment during the manufacturing process to determine whether the product is in good condition.

[0003] In related technologies, the FCT testing equipment includes a testing body, on which a testing platform and a clamping fixture are mounted. The testing platform is horizontally positioned and opposite the clamping fixture, which is located directly above it. Multiple pressure rods are mounted on the bottom surface of the clamping fixture. The clamping fixture is raised and lowered onto the testing body via a lifting mechanism. When performing functional testing on the motherboard, the motherboard is placed on the testing platform, and the pressure rods are lowered using the lifting mechanism until they clamp the motherboard onto the platform. At this point, the testing platform is powered on to test the motherboard's functionality. After the test is completed, the pressure rods are raised again using the lifting mechanism to remove the tested motherboard. This process is repeated for subsequent motherboards. When a defective product is detected, it is removed and placed in a designated defective product area for centralized processing.

[0004] The motherboard transportation and placement in the above process are all done manually by workers. During the testing process, there may be positional errors when the motherboard is placed on the test bench, and the clamping force of the pressure bar on the test bench may decrease after the equipment has been used for a long time, resulting in poor contact between the motherboard and the test bench. This can cause "false damage" during the motherboard functional test, and a qualified product may be judged as a defective product, resulting in product waste. Summary of the Invention

[0005] This application provides a motherboard FCT testing device to at least solve the problem of accidental damage and product waste that is easily caused during motherboard functional testing in related technologies.

[0006] According to one embodiment of this application, a motherboard FCT testing device is provided, comprising: a first conveying device; a first testing body through which the first conveying device passes; a second conveying device; a second testing body through which the second conveying device passes; a good product conveying device; and a transition mechanism located at the intersection of the conveying end of the first conveying device, the conveying beginning of the second conveying device, and the conveying beginning of the good product conveying device, and conveying the motherboard conveyed by the first conveying device to the second conveying device or the good product conveying device according to the test results.

[0007] In one exemplary embodiment, there is a height difference between the first conveying device and the second conveying device. The transition mechanism includes a transition platform that is rotatable and liftable, and has a first position flush with the first conveying device, a second position flush with the second conveying device, and a flipped position at a height between the first and second positions and tilted.

[0008] In an exemplary embodiment, the transition platform includes a first side and a second side disposed opposite to each other, the first side being closer to the first conveying device than the second side. When the transition platform is flipped, the height of the first side is higher than the height of the second side. The transition mechanism also includes a stop assembly located on the second side. When the transition platform is flipped, the main board abuts against the stop assembly to be fully supported on the transition platform.

[0009] In one exemplary embodiment, the stop assembly includes: a base disposed on a transition platform; a telescopic rod movably extending longitudinally within the base, wherein when the transition platform is in a flipped position, the telescopic rod extends out of the base and is located on the movement path of the main board to stop the main board; and an elastic member abutting against the telescopic rod and providing elastic force for the telescopic rod to extend out of the base.

[0010] In one exemplary embodiment, the stop assembly further includes a limiting frame located on the good product conveying device. When the transition platform is in the first position, the limiting frame is located on the movement path of the telescopic rod and limits the telescopic rod within the base to avoid the conveying of the motherboard.

[0011] In one exemplary embodiment, the transition platform includes an upper platform and a lower platform, the lower platform being located below the upper platform, the motherboard being supported on the upper platform, and the second side of the lower platform having an extension extending directly below the upper platform, with a stop assembly located at the extension.

[0012] In one exemplary embodiment, the transition mechanism further includes: a transition drive member; a first rod body, which is drivenly connected to the transition drive member; a second rod body, which is threadedly engaged with the first rod body and connected to the transition platform, wherein when the transition drive member drives the first rod body to rotate, it causes the second rod body to move axially, and the second rod body causes the transition platform to rise and fall; and a limiting member, which engages with the second rod body and prevents the second rod body from rotating.

[0013] In one exemplary embodiment, the second rod is rotatably connected to the transition platform, and the rotation axis of the transition platform relative to the second rod is not parallel to the axis of the second rod. The transition mechanism further includes: a fixed plate; a slider slidably disposed on the fixed plate; and a support rod connected to the slider and the transition platform, wherein the support rod causes the transition platform to rotate when the slider moves.

[0014] In an exemplary embodiment, the transition mechanism further includes a transmission member connected to and moving synchronously with the second rod. The slider has a first inclined surface located on the movement path of the transmission member. When the second rod moves axially, the transmission member presses against the first inclined surface to push the slider to move. The slider drives the transition platform to flip via the support rod, and the transition platform switches from the first position to the flipped position.

[0015] In one exemplary embodiment, the slider further includes a second inclined surface. The first and second inclined surfaces are located on opposite sides of the slider, and the first and second inclined surfaces have opposite inclination directions. When the transition platform switches from the flip position to the second position, the transmission member abuts against the second inclined surface, the slider moves in the opposite direction, and drives the transition platform to return to horizontal.

[0016] In one exemplary embodiment, the transition mechanism further includes a reset member that abuts against the slider and provides the slider with a reset force that drives the transition platform back to a horizontal position.

[0017] In one exemplary embodiment, the transmission member includes a first segment and a second segment connected in sequence, the first segment being connected to the side of the second rod and extending radially, and the second segment extending axially along the second rod.

[0018] In one exemplary embodiment, the fixing plate has a groove, at least a portion of the slider is accommodated in the groove, the bottom surface of the groove has a dovetail groove, the width of the opening of the dovetail groove is smaller than the width of the bottom, and the slider has a protrusion adapted to the shape of the dovetail groove, the protrusion being located within the dovetail groove.

[0019] In one exemplary embodiment, the support rod has a clearance groove for accommodating a second rod, the clearance groove extending axially along the support rod, and the second rod passing through the clearance groove.

[0020] In one exemplary embodiment, the transition mechanism further includes: a fixed plate; a slider slidably disposed on the fixed plate; a support rod connected to the slider and the transition platform, wherein the support rod causes the transition platform to rotate when the slider moves; and a drive mechanism connected to the slider and driving the slider to move.

[0021] In one exemplary embodiment, the transition mechanism further includes a sensor located on the transition platform and capable of sensing the state of the motherboard on the transition platform to control the operation of the transition mechanism.

[0022] In one exemplary embodiment, the motherboard FCT testing equipment further includes a pushing mechanism, and the pushing mechanism and the second conveying device are located on opposite sides of the transition mechanism, respectively.

[0023] In one exemplary embodiment, the pushing mechanism includes a pushing drive and a pushing plate. The pushing plate is driven to move by the pushing drive, and the pushing plate pushes the main board on the transition mechanism to the second conveying device.

[0024] In an exemplary embodiment, the first conveying device and / or the second conveying device include an input section, an intermediate section and an output section that are sequentially connected along the conveying direction. The intermediate section passes through the first test body or the second test body and is vertically movable. When the motherboard is conveyed to the test position of the first test body or the second test body, the intermediate section descends to place the motherboard in the first test body or the second test body.

[0025] In an exemplary embodiment, the first test body and / or the second test body includes: a housing having a cavity with a channel on the side of the cavity, through which a first conveying device or a second conveying device passes; a test platform located inside the cavity and below the first conveying device or the second conveying device; and a lifting mechanism movably disposed above the test platform and capable of moving up and down to test the motherboard.

[0026] In one exemplary embodiment, the lifting mechanism includes: a lifting drive member, the output shaft of which extends into the cavity; a pressure plate located directly above the test platform and drivenly connected to the output shaft of the lifting drive member; a pressure rod located at the bottom of the pressure plate; a guide rod passing through the housing, with its two ends connected to the lifting drive member and the pressure plate, respectively; and a shock absorber sleeved on the guide rod, with its two ends abutting against the housing and the lifting drive member, respectively.

[0027] In one exemplary embodiment, the motherboard FCT testing equipment further includes: a reversing conveyor located at the conveying end of the second conveyor; a scrap conveyor; and a test-pending conveyor, which are connected to the reversing conveyor. The reversing conveyor can convey the motherboard to the scrap conveyor or the test-pending conveyor based on the test results of the second test unit.

[0028] This application incorporates a second conveying device and a second testing machine. The second conveying device, working in conjunction with the second testing machine, can re-verify defective products after the first testing machine's inspection, thus avoiding product waste due to testing errors. Simultaneously, this embodiment also includes a transition mechanism. This transition mechanism can transport the motherboard, after testing by the first testing machine, to the second conveying device for verification or to a good-product conveying mechanism as a qualified product for subsequent transport, based on the test results. Specifically, the motherboard to be tested is conveyed or placed on the first conveying device, which then transports it to the first testing machine for testing. After testing, the motherboard is transported by the first conveying device to the transition mechanism. Based on the test results of the first testing machine, if the test result is qualified, the first conveying device directly transports the motherboard to the good-product conveying mechanism. If the test result is unqualified, the transition mechanism transports the motherboard to the second conveying device, which then transports it to the second testing machine for verification testing. After testing, the motherboard is transported by the second conveying device to the subsequent production line. The above settings improve the problem of "false positives" during motherboard function testing caused by prolonged use of the equipment, which would mistake qualified products for defective ones and result in product waste. This helps to improve testing efficiency and accuracy. Attached Figure Description

[0038] The embodiments of this application will be described in detail below with reference to the accompanying drawings and examples.

[0039] It should be noted that the terms "first," "second," etc., in the specification, claims, and drawings of this application are used to distinguish similar objects and are not necessarily used to describe a specific order or sequence.

[0040] To address the problem of accidental damage and product waste during motherboard functional testing in related technologies, this application provides a motherboard FCT testing device.

[0041] like Figures 1 to 7 The motherboard FCT testing equipment shown includes a first conveying device 10, a first testing body 20, a second conveying device 30, a second testing body 40, a good product conveying device 50, and a transition mechanism 60. The first conveying device 10 passes through the first testing body 20; the second conveying device 30 passes through the second testing body 40; the transition mechanism 60 is located at the intersection of the conveying end of the first conveying device 10, the conveying beginning of the second conveying device 30, and the conveying beginning of the good product conveying device 50, and conveys the motherboard conveyed by the first conveying device 10 to the second conveying device 30 or the good product conveying device 50 according to the test results.

[0042] This embodiment includes a second conveying device 30 and a second testing machine 40. The second conveying device 30 works in conjunction with the second testing machine 40 to re-verify defective products after testing by the first testing machine 20, thus avoiding product waste due to testing errors. Simultaneously, this embodiment also includes a transition mechanism 60, which can transport the motherboard tested by the first testing machine 20 to the second conveying device 30 for re-verification or to the good product conveying mechanism as a qualified product for subsequent transport, based on the test results. Specifically, the motherboard to be tested is conveyed or placed on the first conveyor device 10. The first conveyor device 10 conveys the motherboard to the first testing unit 20 for testing. After the test, it is conveyed out by the first conveyor device 10 to the transition mechanism 60. Based on the test results of the first testing unit 20, if the test result is qualified, the first conveyor device 10 directly conveys it to the good product conveyor device 50 through the transition mechanism 60. If the test result is unqualified, the transition mechanism 60 conveys the motherboard to the second conveyor device 30. The second conveyor device 30 conveys it to the second testing unit 40 for verification testing. After the test, it is conveyed out through the second conveyor device 30 to the subsequent production line. This setup improves the problem of "false positives" during motherboard functional testing after long-term use of the equipment, where qualified products are judged as defective products, resulting in product waste. It helps to improve testing efficiency and accuracy.

[0043] In this embodiment, there is a height difference between the first conveying device 10 and the second conveying device 30; more specifically, the height of the first conveying device 10 is higher than the height of the second conveying device 30. Based on this, the transition mechanism 60 of this embodiment includes a transition platform 61. The transition platform 61 is rotatable and height-adjustable, and has a first position flush with the first conveying device 10, a second position flush with the second conveying device 30, and a tilted position at a height between the first and second positions. Thus, when the motherboard is conveyed from the first conveying device 10 to the second conveying device 30, the transition platform 61 is initially in the first position, at which point the motherboard can be partially conveyed onto the transition platform 61. Then, the transition platform 61 switches to the tilted position. It should be noted that this tilting position is not a horizontal to vertical tilt, but rather a tilting angle, so that the transition platform 61 is in a tilted state. The purpose of this arrangement is to allow the motherboard to slide completely onto the transition platform 61 under gravity, avoiding interference between the motherboard and the first conveying device 10 during descent if the motherboard remains partially on the first conveying device 10, thus ensuring the safety of the motherboard. When the transition platform 61 is in the flip position, the motherboard is completely on the transition platform 61 and descends with the transition platform 61. When the motherboard switches to the second position, the motherboard descends to a position flush with the second conveyor device 30, and the motherboard can be conveyed onto the second conveyor device 30 for verification testing.

[0044] like Figure 1 As shown, in this embodiment, the good product conveying device 50 and the first conveying device 10 are aligned and coaxially arranged, forming a straight conveyor line. The second conveying device 30 is located on one side of this conveyor line and its height is reduced. In this embodiment, the first conveying device 10, the good product conveying device 50, and the second conveying device 30 are arranged in a T-shape, and the transition mechanism 60 is located at the intersection of the T-shape, thus serving as a transfer mechanism for the main board. Of course, the specific arrangement of the first conveying device 10, the second conveying device 30, and the good product conveying device 50 can be adjusted as needed, and the height of the second conveying device 30 can also be adjusted as needed.

[0045] The transition platform 61 in this embodiment includes a first side and a second side arranged opposite to each other. The first side is closer to the first conveying device 10 than the second side. The first side is the side closer to the first conveying device 10, while the second side is the side closer to the good product conveying device 50. Thus, along the conveying direction, the good product motherboard will first pass through the first side and then through the second side, thereby being conveyed onto the good product conveying device 50. When the transition platform 61 is flipped, the height of the first side is higher than the height of the second side. To ensure the safety of motherboard conveying, this embodiment adopts the method of raising the height of the first side and lowering the height of the second side to achieve the flipping of the transition platform 61. In this way, the motherboard can safely slide onto the transition platform 61, avoiding damage caused by the motherboard being supported on only one side.

[0046] To ensure that the motherboard can be smoothly transported directly from the first conveying device 10 to the good product conveying device 50, this embodiment adopts a setting where the distance between the two sides of the transition platform 61 along the direction from the first conveying device 10 to the transition platform 61 is less than the length of the motherboard in that direction. That is, the interval between the first conveying device 10 and the good product conveying device 50 is less than the length of the motherboard on that side. In this way, when the motherboard is directly transported from the first conveying device 10 to the good product conveying device 50 via the transition platform 61, at least one side of the motherboard will cooperate with either the first conveying device 10 or the good product conveying device 50, so that the motherboard will inevitably be driven and transported by at least one of the first conveying device 10 and the good product conveying device 50, thereby achieving smooth transport.

[0047] At the same time, such as Figure 3 , Figure 4 and Figure 7As shown, the transition mechanism 60 also includes a stop component 62, located on the second side. The main function of the stop component 62 is to stop the motherboard when the transition platform 61 is flipped, preventing the motherboard from slipping off the tilted transition platform 61 and ensuring that the motherboard is stably supported on the transition platform 61. Specifically, when the transition platform 61 is flipped, it changes from a horizontal state to a tilted state, and the tilt angle increases over time. At this time, the motherboard slides from the first side to the second side of the transition platform 61 until one side of the motherboard abuts against the stop component 62. At this point, the motherboard is fully supported on the transition platform 61, and even if the transition platform 61 continues to flip, the motherboard will not continue to slide.

[0048] In this embodiment, the stop assembly 62 is a telescopic assembly. Specifically, the stop assembly 62 includes a base 621, a telescopic rod 622, and an elastic element 623. The base 621 is fixedly mounted on the transition platform 61 and adopts an upright sleeve structure. The telescopic rod 622 is movably and longitudinally inserted into the base 621, allowing it to extend and retract relative to the base 621. The elastic element 623 can be a spring, housed within the base 621 and abutting against the telescopic rod 622. The elastic element 623 provides the telescopic rod 622 with the elastic force to extend out of the base 621. Thus, when the transition platform 61 is in the flipped position, the telescopic rod 622 automatically extends under the action of the elastic element 623, moving into the movement path of the main board and stopping the main board, thereby providing a stopping and limiting function for the main board. Of course, in addition to the telescopic component mentioned above, the stop assembly 62 can also adopt other structural forms, such as a rotating rod. The rod can rotate, and when a stop is needed, the rod rotates to a vertical position to stop the main board. When not needed, it can be rotated and retracted.

[0049] In this embodiment, the stop assembly 62 itself does not have a motor or other driving components. Therefore, in order to prevent the telescopic rod 622 from extending arbitrarily and affecting the conveying of the main board to the good product conveying device 50, the stop assembly 62 in this embodiment also includes a limiting frame 624 located on the good product conveying device 50. The limiting frame 624 is located at the conveying head end of the good product conveying device 50, that is, the end that docks with the transition platform 61. In this embodiment, the limiting frame 624 adopts an L-shaped plate structure, which includes a horizontal plate and a vertical plate. The vertical plate is connected to the frame of the good product conveying device 50, while the horizontal plate extends laterally toward the transition platform 61 and extends above the telescopic rod 622 and is not higher than the height of the conveyor belt. Thus, when the transition platform 61 is in the first position, the limiting frame 624 is located on the movement path of the telescopic rod 622. The horizontal plate of the limiting frame 624 stops the telescopic rod 622, thereby limiting the telescopic rod 622 within the base 621. This ensures that the extension distance of the telescopic rod 622 is very small, preventing it from extending onto the conveyor belt and thus avoiding obstruction of the motherboard's transport, without affecting the normal transport of the motherboard. When the transition platform 61 flips, since the limiting frame 624 remains stationary, it no longer limits or stops the telescopic rod 622 as the platform flips. The telescopic rod 622 can then gradually extend out of the base 621 to stop the motherboard. Of course, in addition to the above method, the telescopic rod 622 can also be driven by components such as motors or cylinders to achieve the same stopping and obstruction of the motherboard.

[0050] like Figure 3 and Figure 4 As shown, in this embodiment, the transition platform 61 includes an upper platform 611 and a lower platform 612. The lower platform 612 is located below the upper platform 611, and the two are connected as a whole by a connecting column. The motherboard is supported on the upper platform 611, which is also the main part for conveying the motherboard. The upper platform 611 and the lower platform 612 are not the same size; the lower platform 612 is larger than the upper platform 611. This results in the lower platform 612 having an extension section extending directly below the upper platform 611 on its second side. The stop component 62 is located on the extension section. Thus, when the telescopic rod 622 extends a small distance or does not extend at all, the telescopic rod 622 will not exceed the height of the upper platform 611. This allows the transition mechanism 60 to be inactive when the motherboard is conveyed from the first conveying device 10 to the good product conveying device 50. Driven by the first conveying device 10 and the good product conveying device 50, the motherboard can easily cross the transition platform 61 without being affected by components such as the stop component 62, ensuring smooth conveying. This design takes into account that most motherboards are good products. Therefore, when the first test unit 20 is good, the transition mechanism 60 does not need to operate, thus quickly transporting the motherboard. The transition platform 61 only needs to operate when the motherboard fails the test, which can speed up the overall work efficiency.

[0051] In this embodiment, the transition mechanism 60 further includes a lifting component and a tilting component. Both the lifting component and the tilting component are connected to the lower platform 612 of the transition platform 61. The lifting component drives the transition platform 61 to move up and down, while the tilting component drives the transition platform 61 to tilt. The two components can be structurally independent, and their movement can be synchronously controlled by a control program. Alternatively, they can be driven in a coordinated manner, where movement of one component can drive movement of the other component, thus enabling one drive to achieve the movement of both components and achieving synchronous lifting and tilting of the transition platform 61. This embodiment adopts the second method described above.

[0052] like Figure 4 As shown, the lifting assembly in this embodiment includes a transition drive component 63, a first rod 64, a second rod 65, and a limiting component 66. The transition drive component 63 can be a motor or similar component. The first rod 64 is driven and connected to the transition drive component 63, while the second rod 65 is threadedly engaged with the first rod 64 and connected to the transition platform 61. Thus, when the transition platform 61 needs to be raised or lowered, the transition drive component 63 drives the first rod 64 to rotate, and the first rod 64, through its threaded structure, drives the second rod 65 to move axially, thereby raising or lowering the transition platform 61. The limiting member 66 cooperates with the second rod 65 and prevents the second rod 65 from rotating, thereby preventing the second rod 65 from rotating and allowing the second rod 65 to move only axially. The cooperation method between the limiting member 66 and the second rod 65 can be set as needed. For example, a protrusion can be provided on the limiting member 66 and a groove extending vertically can be provided on the second rod 65. The protrusion is located in the groove to guide and limit the second rod 65. Alternatively, a non-circular second rod 65 can be used, and a part of the limiting member 66 can be sleeved on the outside of the second rod 65 to prevent the second rod 65 from rotating.

[0053] It should be noted that the second rod 65 and the transition platform 61 in this embodiment are not fixedly connected, but are rotatably connected, or more specifically, hinged. Furthermore, the rotation axis of the transition platform 61 relative to the second rod 65 is not parallel to the axis of the second rod 65, but is perpendicular to it. In this way, the second rod 65 can only drive the transition platform 61 to rise and fall, but will not drive the transition platform 61 to rotate.

[0054] The flipping assembly of this embodiment includes a fixed plate 67, a slider 68, and a support rod 69. The fixed plate 67 is arranged horizontally, the slider 68 is slidably arranged on the fixed plate 67, and the two ends of the support rod 69 are respectively connected to the bottom of the second side of the lower platform 612 of the transition platform 61 and the slider 68. In this way, in conjunction with the hinged connection between the second rod 65 and the transition platform 61, the slider 68 can drive the transition platform 61 to flip around the hinge point through the support rod 69 when it moves.

[0055] The transition mechanism 60 in this embodiment also includes a transmission member 610, which is configured to connect the lifting assembly and the tilting assembly. Specifically, the transmission member 610 is connected to the side of the second rod 65 and moves up and down synchronously with the second rod 65. The slider 68 is a wedge-shaped block with a first inclined surface 681, which is located on the movement path of the transmission member 610. When the second rod 65 moves axially downward, the transmission member 610 contacts and presses the first inclined surface 681. Under the action of the first inclined surface 681, the slider 68 is pushed to move away from the second rod 65. The movement of the slider 68, in turn, drives the transition platform 61 to tilt via the support rod 69. In this way, the transition platform 61 tilts while descending, switching the transition platform 61 from the first position to the tilted position.

[0056] Accordingly, the slider 68 also includes a second inclined surface 682. The first inclined surface 681 and the second inclined surface 682 are located on opposite sides of the slider 68. In this embodiment, the first inclined surface 681 is disposed on the upper side of the slider 68 near the end of the second rod 65, and the second inclined surface 682 is disposed on the lower side of the slider 68 near the end of the second rod 65. The inclination directions of the first inclined surface 681 and the second inclined surface 682 are opposite. Thus, when the transition platform 61 has moved to the flipped position, and the second rod 65 continues to move axially downward, the transmission component 610 no longer contacts the first inclined surface 681. The tip of the transmission component 610, located between the first inclined surface 681 and the second inclined surface 682, abuts against the side of the transmission component 610. At this time, the transition platform 61 only has lifting and lowering motion and will not continue to flip. Then, the transmission component 610 continues to move downward and abuts against the second inclined surface 682. At this time, due to the action of the second inclined surface 682, the slider 68 moves in the opposite direction and moves towards the second rod 65. The movement of the slider 68 drives the transition platform 61 to flip in the opposite direction through the support rod 69, so that the transition platform 61 gradually returns to a horizontal state, realizing the transition platform 61 switching from the flipped position to the second position.

[0057] In this embodiment, the transition mechanism 60 further includes a reset member 620, which can be a spring or other component. One end of the reset member 620 abuts against the fixed plate 67, and the other end abuts against the slider 68, thereby providing a reset force to the slider 68 to move towards the second rod 65. This ensures that the slider 68, driven by the reset member 620, always has a tendency to move the transition platform 61 back to a horizontal position. This ensures that one end of the slider 68 always remains in contact with the transmission member 610, guaranteeing a tight fit between them, and ensuring a tight fit between the transmission member 610 and the first inclined surface 681 and the second inclined surface 682.

[0058] In this embodiment, the transmission component 610 includes a first segment 6101 and a second segment 6102 connected by sequential bending. The first segment 6101 and the second segment 6102 form an L-shaped structure. The first segment 6101 is connected to the side of the second rod 65 and extends radially along the second rod 65. The second segment 6102 is connected to the end of the first segment 6101 away from the second rod 65 and extends axially along the second rod 65. The top end of the second segment 6102 is flush with the end of the first segment 6101. Thus, the second segment 6102 is the part that mates with the slider 68. The side of the second segment 6102 abuts against the first inclined surface 681, the second inclined surface 682, and the tip between them, thereby driving the flipping component. The length of the second segment 6102 can be appropriately set during the design to change the time when the transition platform 61 is in the flipping position.

[0059] like Figure 4 , Figure 5 and Figure 6 As shown, in this embodiment, the fixing plate 67 has a transversely opened slide groove 671, at least a portion of the slider 68 is accommodated in the slide groove 671, so that the slider 68 can move along the slide groove 671, and a portion of the reset member 620 is also accommodated in the slide groove 671. In this embodiment, a dovetail groove 672 is also provided on the bottom surface of the slide groove 671. The width of the opening of the dovetail groove 672 is smaller than the width of the bottom, that is, a structure that is narrower at the top and wider at the bottom. Correspondingly, the slider 68 has a protrusion 683 that matches the shape of the dovetail groove 672. The protrusion 683 is located inside the dovetail groove 672, and both the slide groove 671 and the dovetail groove 672 are connected to the outer side of the fixing plate 67 near the second rod 65. In this way, during installation, the slider 68 can be slid into the slide groove 671 from the side of the fixing plate 67, and the protrusion 683 also slides into the dovetail groove 672. Through the cooperation of the protrusion 683 and the dovetail groove 672, the slider 68 can only slide laterally and cannot move up and down, thereby ensuring the reliability of the movement of the slider 68 and thus ensuring the reliability of the flipping of the transition platform 61. Of course, a limiting structure can also be set separately to limit the movement of the slider 68.

[0060] In this embodiment, the support rod 69 is located at the middle of the second side of the transition platform 61, and the second rod 65 is also hinged to the center of the transition platform 61. Therefore, there will be some interference between the support rod and the second rod 65. To avoid this situation, this embodiment provides a clearance groove 691 on the support rod 69. The clearance groove 691 extends along the axial direction of the support rod 69 and is used to avoid the second rod 65. The second rod 65 passes through the clearance groove 691. In this way, when the support rod 69 moves, the second rod 65 can move relative to it within the clearance groove 691, thereby achieving clearance between the support rod 69 and the second rod 65. Of course, the support rod 69 can also avoid the position of the second rod 65, and the number can also be set according to needs. For example, one or more support rods 69 can be set on both sides of the second rod 65, in which case the clearance groove 691 does not need to be provided.

[0061] Besides the method described in this embodiment of associating the tilting mechanism with the lifting mechanism 23, the lifting component and the tilting component can also be set independently. For example, the lifting component is the same as described above, and the tilting component, in addition to the fixed plate 67, slider 68, and support rod 69, also includes a drive mechanism. The drive mechanism is driven and connected to the slider 68, and drives the slider 68 to move. The drive mechanism and the transition drive component 63 can be associated through a control program to unify the control of their actions, thereby achieving the effect of simultaneous lifting and tilting.

[0062] In this embodiment, the transition mechanism 60 further includes a sensor 630, which is located on the upper platform 611 of the transition platform 61 and can sense the status of the motherboard on the transition platform 61 to control the operation of the transition mechanism 60. When the sensor 630 detects that the motherboard has reached the middle of the transition platform 61, the sensor 630 can send an action command to the transition drive 63 through the controller, and the lifting component and the flipping component can then operate.

[0063] The overall operation process of the transition mechanism 60 in this embodiment is as follows:

[0064] Initially, the transition mechanism 60 remains in the first position. If the first test unit 20 tests the motherboard and it is found to be a qualified product, the transition mechanism 60 remains in the first position.

[0065] If the mainboard tested by the first testing unit 20 is found to be defective, it needs to be transported to the second conveying device 30. The sensor 630 of the transition mechanism 60 senses the position of the mainboard. When the mainboard is sensed, it indicates that it has reached the middle of the transition platform 61. The transition drive 63 then activates, driving the first rod 64 to rotate. The first rod 64 drives the second rod 65 to move downwards, and the second rod 65 drives the entire transition platform 61 to move downwards. Simultaneously, the second rod 65 drives the transmission component 610 to move downwards. The transmission component 610 contacts and presses against the first inclined surface 681, pushing the slider 68 away from the second rod 65. The slider 68 drives the support rod 69 to move, causing the entire transition platform 61 to flip. As the transition platform 61 flips, the telescopic rod 622 gradually extends out of the base 621 and moves onto the mainboard's movement path. Under the influence of gravity, the mainboard slides down to the second side of the transition platform 61 and abuts against the telescopic rod 622. The transition platform 61 then switches from the first position to the flipped position. Then, with the movement of the transition drive 63, the transition platform 61 continues to descend. The transmission component 610 separates from the first inclined surface 681 and abuts against the tip of the slider 68. Subsequently, the transmission component 610 contacts and presses against the second inclined surface 682. Under the push of the reset component 620, the slider 68 moves towards the second rod 65. The movement of the slider 68 drives the support rod 69 to move in the opposite direction. The support rod 69 drives the transition platform 61 to flip in the opposite direction, so that the transition platform 61 gradually returns to a horizontal state. As the transition platform 61 descends to a position flush with the second conveying device 30, the transition platform 61 also returns to a horizontal state, thus switching from the flipped position to the second position. The motherboard can then be conveyed to the second conveying device 30 for testing again by the second test unit 40. After the motherboard exits the transition platform 61, the transition platform 61 resets as a whole, returning to the first position to await the next action. The reset process is the reverse of the above process and will not be described in detail here.

[0066] It should be noted that the specific structure of the transition mechanism 60 is not limited to the above-described configuration in this embodiment; it can also be implemented by using a common reversing mechanism to switch the conveying direction.

[0067] like Figure 3 As shown, in this embodiment, the motherboard FCT testing equipment further includes a pushing mechanism 100. The pushing mechanism 100 and the second conveying device 30 are located on opposite sides of the transition mechanism 60, and the pushing mechanism 100 and the second conveying device 30 are on the same plane. Thus, when the transition platform 61 is in the second position, the pushing mechanism 100 can operate to push the motherboard from the transition platform 61 onto the second conveying device 30. Alternatively, the motherboard can be conveyed through the cooperation between the transition platform 61 itself and the second conveying device 30.

[0068] The pushing mechanism 100 in this embodiment includes a pushing drive and a pushing plate. The pushing drive can be a cylinder or other components. The pushing plate is driven to connect with the pushing drive. When the transition platform 61 is in the second position, the pushing drive is activated, driving the pushing plate to move closer to the main board. The pushing plate can then push the main board on the transition platform 61 to the second conveying device 30, and the second conveying device 30 can then perform subsequent conveying.

[0069] In this embodiment, the first conveying device 10, the second conveying device 30, and the good product conveying device 50 all adopt a conveyor belt structure. Each device includes a mounting frame and a conveyor belt, with the conveyor belt mounted on the mounting frame. Along the horizontal direction perpendicular to the conveying direction, the conveyor belts are spaced apart on both sides of the mounting frame, forming gaps between them. The opposite sides of the main board are supported on the conveyor belts on both sides. This ensures the conveying and support of the main board while allowing the bottom center of the main board to be hollowed out, reducing contact between the conveyor belt and the main board, minimizing wear on the main board during conveyor belt movement, and reducing the impact of the conveyor belt on the main board.

[0070] The cooperation between the first conveying device 10 and the first testing body 20 in this embodiment is the same as the cooperation between the second conveying device 30 and the second testing body 40. Based on this, the structures of the first conveying device 10 and the second conveying device 30 in this embodiment are the same. Similarly, the structures of the first testing body 20 and the second testing body 40 are also the same. Of course, they can also be configured with different structural forms.

[0071] Taking the first conveying device 10 and the first testing body 20 as examples, such as Figure 1 As shown, the first conveying device 10 includes an input section 11, an intermediate section 12, and an output section 13 sequentially connected along the conveying direction. The input section 11 and output section 13 only need to be aligned with the intermediate section 12 to achieve motherboard conveying; they do not necessarily need to be connected together. Both the input section 11 and output section 13 are located outside the first testing unit 20, while the intermediate section 12 is installed inside the first testing unit 20. Furthermore, the intermediate section 12 is designed to be height-adjustable. Thus, when the motherboard is conveyed to the testing position inside the first testing unit 20 via the intermediate section 12 of the first conveying device 10, the intermediate section 12 can be lowered, thereby placing the motherboard on the testing table 22 of the first testing unit 20, enabling the first testing unit 20 to perform testing. The height adjustment of the intermediate section 12 can be achieved by using a lifting cylinder or similar method.

[0072] like Figure 2As shown, in this embodiment, the first test body 20 includes a housing 21, a test platform 22, and a lifting mechanism 23. The housing 21 has a cavity 211, with a channel 212 opened on the side of the cavity 211. Channels 212 are also opened on opposite sides of the cavity 211, allowing the middle section 12 of the first conveying device 10 to pass through the channel 212 and thus through the housing 21, enabling the transport of the motherboard. The test platform 22 is located inside the cavity 211 and below the first conveying device 10. The upper surface of the test platform 22 serves as the test surface, on which the motherboard is placed. When the middle section 12 transports the motherboard to a position directly above the test platform 22, the middle section 12 descends to place the motherboard onto the test platform 22 for testing. After testing, the middle section 12 rises to reconnect the motherboard with the conveyor belt for further transport. The lifting mechanism 23 is movably positioned above the test platform 22, allowing it to move up and down to perform testing on the motherboard.

[0073] The lifting mechanism 23 in this embodiment includes a lifting drive component 231, a pressure plate 232, a pressure rod 233, a guide rod 234, and a shock absorber 235. The lifting drive component 231 can be a cylinder, with its cylinder body fixedly mounted on the outer upper surface of the housing 21. The output shaft passes through the upper part of the housing 21 and extends into the cavity 211, located above the test platform 22. The pressure plate 232 is located directly above the test platform 22 inside the housing 21 and is driven by the output shaft of the lifting drive component 231. The lifting drive component 231 can drive the pressure plate 232 to move up and down. The pressure rod 233 is located at the bottom of the pressure plate 232 and can be used to test the main board. The number of pressure rods 233 can be set as needed; this embodiment has multiple pressure rods 233. A guide rod 234 passes through the housing 21. Both ends of the guide rod 234 are connected to the cylinder of the lifting drive 231 and the pressure plate 232, respectively. The guide rod 234 guides the up-and-down movement of the pressure plate 232, ensuring the reliability of its movement. A shock absorber 235 is located on the outer upper surface of the housing 21. The shock absorber 235 can be a spring, which is sleeved on the guide rod 234. Both ends of the shock absorber 235 abut against the housing 21 and the output shaft of the lifting drive 231, respectively. When the output shaft moves up and down, it compresses the shock absorber 235, thus providing shock absorption. To facilitate the abutment of the shock absorber 235, this embodiment provides a radially extending connecting rod on the top side of the output shaft, with the top of the shock absorber 235 abutting against the connecting rod. In this embodiment, there are two guide rods 234 and two shock absorbers 235, and the two guide rods 234 are located on opposite sides of the lifting drive component 231, thereby ensuring force balance.

[0074] like Figure 1As shown, in this embodiment, the motherboard FCT testing equipment also includes a reversing conveyor 70, a scrap conveyor 80, and a test-pending conveyor 90. Similar to the aforementioned first conveyor 10, the reversing conveyor 70, scrap conveyor 80, and test-pending conveyor 90 also employ a conveyor belt structure. The reversing conveyor 70 is located at the end of the second conveyor 30, while both the scrap conveyor 80 and the test-pending conveyor 90 are connected to the reversing conveyor 70, and all three are located on the same plane. The reversing conveyor 70 can change the conveying direction of the motherboard. During conveying, the reversing conveyor 70 can convey the motherboard to the scrap conveyor 80 or the test-pending conveyor 90 based on the test results of the second testing unit 40. If the result of the second test unit 40 is qualified, the motherboard needs to be further manually verified. The reversing conveyor 70 will transport the motherboard to the inspection product conveyor 90 for subsequent manual verification. If the result of the second test unit 40 is unqualified, the motherboard is scrap. The reversing conveyor 70 will transport the motherboard to the scrap conveyor 80 for subsequent recycling.

[0075] The overall usage process of the motherboard FCT testing equipment in this embodiment is as follows:

[0076] When performing functional testing on the motherboard to be tested, the motherboard to be tested is first placed on the input section 11 of the first conveying device 10, and transported from the input section 11 to the intermediate section 12. After entering the housing 21 of the first test machine 20 and being directly above the test platform 22, the first conveying device 10 and the good product conveying device 50 stop synchronously. Then, the intermediate section 12 is lowered by the lifting cylinder until the bottom of the motherboard is placed on the test platform 22. At this time, the lifting drive component 231 is activated, and the driving pressure rod 233 is lowered to clamp the motherboard on the test platform 22. The power supply on the test platform 22 is then turned on to perform the motherboard functional test.

[0077] After the test is completed, the pressure bar 233 rises, and then the middle section 12 rises and resets. Then the first conveying device 10 and the good product conveying device 50 start synchronously. The motherboard after the test is completed is conveyed from the middle section 12 to the output section 13. The next motherboard to be tested enters the casing 21 of the first test body 20. The above steps are repeated to perform functional tests on the motherboards one by one.

[0078] After testing, the motherboard moves to the output section 13 and reaches the transition mechanism 60. If the motherboard test result is qualified, it is directly conveyed from the top surface of the transition platform 61 to the good product conveyor 50 for good product discharge. If the motherboard test result is unqualified, the motherboard moves to the top surface of the transition platform 61. When the sensor detects that the motherboard has moved to the middle of the transition platform 61, the transition drive 63 is activated. The transition drive 63 drives the first rod 64 to rotate. Under the limit of the limit member 66, the second rod 65 is driven to descend, thereby realizing the descent of the transition platform 61.

[0079] During the descent of the second rod 65, the bottom end of the transmission component 610 abuts against the first inclined surface 681. As the second rod 65 descends, the transmission component 610 descends accordingly, thereby driving the slider 68 to slide to the left through the first inclined surface 681, causing the support rod 69 to rotate, which in turn drives the transition platform 61 to rotate, so that the transition platform 61 rotates and descends at the same time. At this time, the reset component 620 is in a compressed state. At the same time, the main board slides towards the telescopic rod 622 until the main board abuts against the telescopic rod 622, and is able to descend the main board to pass through the gap between the first conveying device 10 and the good product conveying device 50.

[0080] Then, as the second rod 65 continues to descend, the transmission component 610 also continues to descend until the right end of the slider 68 abuts against the left side wall of the transmission component 610, placing the main board below the first conveying device 10 and the good product conveying device 50. The vertical length of the transmission component 610 can be set according to actual conditions. When the right end of the slider 68 abuts against the top of the left side wall of the transmission component 610, the transition platform 61 reaches the flip position.

[0081] As the second rod 65 continues to descend, the top surface of the transmission component 610 abuts against the second inclined surface 682, and the reset component 620 gradually extends until the slider 68 is reset to its initial state. At the same time, it also drives the transition platform 61 to return to a horizontal state. At this time, the top surface of the transition platform 61 is flush with the conveying surface of the second conveying device 30.

[0082] At this point, the pusher drive is activated, causing the pusher plate to move forward, thereby pushing the main board onto the second conveyor device 30. The main board is then conveyed by the second conveyor device 30 to the second testing machine 40 for verification testing. After verification testing, it moves to the output section 13 of the second conveyor device 30, and then to the reversing conveyor device 70. If the verification result is unqualified, the reversing conveyor device 70 moves towards the scrap conveyor device 80, and the main board is conveyed to the scrap area through the scrap conveyor device 80. If the verification result is qualified, the reversing conveyor device 70 moves towards the inspection-ready conveyor device 90, and the inspection-ready conveyor device 90 conveys the main board to the manual area for further verification.
