Description

Technical Field

[0001] The present invention relates to the technical field of motherboard testing, and in particular to an online rapid testing device and method for a microcomputer motherboard. Background Art

[0002] The microcomputer motherboard is one of the most basic and important components in a microcomputer. Usually, the motherboard is a rectangular circuit board on which the main circuit systems and a large number of integrated circuits that make up the computer are installed. The motherboard is not only a platform for the work of various parts in the microcomputer, but also responsible for connecting various components closely together to achieve data transmission and communication. Providing sockets for the main processor, memory sticks and various function cards so that they can be plugged into the motherboard and work normally is also one of the functions of the motherboard. Therefore, plug-in and unplug testing of the sockets on the motherboard is also an important part of the motherboard test by the microcomputer motherboard online test device. The online fast test of the motherboard mainly relies on professional computer hardware and software monitoring software. When testing the sockets on the motherboard, it mainly relies on sensor technology, data transmission technology and data analysis technology.

[0003] A motherboard testing device is disclosed in the patent with announcement number CN112858882A. A supporting frame is added to the rack to support the motherboard, and a fixing component is added to fix the motherboard on the supporting frame, so that the motherboard is not easily displaced during the plug-in test. When the interface on the side wall of the motherboard needs to be plugged in and out, the driving motor is driven to rotate the rotating column, thereby causing the supporting frame to flip over until the angle detection module monitors that the supporting frame is perpendicular to the base. The angle detection module will control the driving motor to stop working and the supporting frame stops flipping. At this time, the driving test component performs a plug-in test on the interface to be tested on the side wall of the motherboard. In this way, the motherboard can be easily flipped at an angle, so that the plug can be inserted into the interface on the side wall of the motherboard for plug-in and plug-out testing.

[0004] However, the prior art still has the following defects: when using the fixing assembly to fix the motherboard on the support bracket, it is necessary to manually pull the fixing blocks with threads connected all around to fix them with the help of the force of the spring, and it is necessary to manually turn the fastening bolts to adjust the position of the fixed moving rod. The operator needs to perform manual operations such as turning multiple times during use, and the same operations need to be performed for different motherboards. When multiple motherboards need to be tested, the operator needs to follow up in real time throughout the process, which requires a large amount of manpower and is more troublesome to operate. Summary of the invention

[0005] In view of the problem in the prior art that when fixing the motherboard on the support bracket through a fixing component, manual operations such as pulling the fixing block or tightening the bolts are required, and the same steps still need to be performed after the motherboard test is completed, a microcomputer motherboard online rapid testing device is proposed.

[0006] The purpose is: by setting a driving component to drive the adjusting component to rotate, thereby driving the clamping component to clamp the mainboard on the storage table. After the test is completed, not only can the clamping plate be moved away from the mainboard, but the mainboard can also be lifted up, which is convenient for replacing the mainboard; and the driving component can drive the linkage component to move, thereby driving the storage table to flip over, so as to test the side plug-in slot of the mainboard on the storage table.

[0008] Furthermore, the adjustment assembly includes a bent rod fixedly mounted on the test bench, a protrusion rotatably mounted on the end of the bent rod, a toothed plate fixedly mounted on one side of the protrusion, a straight rod rotatably mounted on the test bench, and a toothed disc fixedly mounted on the top of the straight rod.

[0009] Furthermore, three groups of tooth blocks are installed in a circumferential array on the tooth plate, and a group of tooth grooves are opened on the tooth disc, and the tooth grooves on the tooth disc are meshed with the tooth blocks on the tooth plate accordingly.

[0010] Further, the driving assembly includes a mounting groove provided inside the test bench, a rectangular hole provided on the test bench, the rectangular hole and the mounting groove being interpenetrating and communicating with each other, a driving motor installed inside the mounting groove, a first bevel gear fixedly installed at an output end of the driving motor, a second bevel gear movably installed in the rectangular hole, the second bevel gear being meshed and connected with the linkage assembly, and a third bevel gear movably installed at the top of the mounting groove; The straight rod passes through the test bench and extends into the mounting groove, and the top of the third bevel gear is fixedly connected to the bottom of the straight rod.

[0011] Further, the linkage assembly includes an L-plate fixedly mounted on one side of the test bench, a connecting rod penetrating the L-plate, a fourth bevel gear and a movable member respectively connected to both ends of the connecting rod, a rack movably connected to the movable member, a transmission wheel meshed with the rack, a connecting rod is mounted on a side of the transmission wheel away from the fourth bevel gear, and the transmission wheel is connected to the movable assembly through the connecting rod; A limiting piece is installed at one end of the connecting rod close to the transmission wheel, and one end of the rack is installed above the transmission wheel through the limiting piece and meshes with the transmission wheel.

[0012] Furthermore, the movable assembly includes an arc-shaped hole penetrating the arc-shaped guide rail, a slider slidably mounted on the arc-shaped guide rail, a vertical rod penetrating the arc-shaped hole and fixedly connected to the slider, and a horizontal rod fixed to the top of the vertical rod and a connecting block fixed to the bottom thereof; The other end of the cross bar is fixedly connected to the storage table through a mounting piece, and the connecting block is fixedly connected to the connecting rod.

[0013] Furthermore, the top of the support rod passes through the storage platform 14 and is fixedly mounted with a storage plate.

[0014] Another object of the present invention is to provide a method for online rapid testing of a microcomputer motherboard, the purpose of which is: during the rapid testing process, the motherboard is clamped and fixed by a clamping assembly, the linkage assembly is driven to move by starting the driving assembly, thereby driving the movable assembly to move in a trajectory, and the motherboard is flipped over, thereby testing the side plug-in slots of the motherboard. After the test is completed, the clamping assembly is unlocked by the adjusting assembly and the motherboard is lifted up, without the need for manual operations such as tightening bolts, and the use is more convenient.

[0015] To achieve the above object, the present invention provides the following technical solution: a microcomputer motherboard online rapid testing method, comprising the following steps: S1, when the mainboard is transmitted through the conveyor belt, the gripping arm grabs the mainboard and places it on the placement plate, so that the placement plate presses the clamping assembly downward, thereby driving the clamping plates on both sides to move toward the middle. At this time, the mainboard is clamped and fixed by the clamping plates, and the adjusting assembly drives the clamping assembly to reset under the action of the driving assembly; S2, when testing the upper surface of the motherboard, the test group drives the sensing group to move up, down, left, and right, so that the motherboards at different positions can be subjected to sensing tests; S3, when testing the side surface of the mainboard, the driving component drives the linkage component to be linked, so that the movable component can be guided on the arc guide rail, thereby realizing the guided rotation of the storage table. When the rotation angle of the storage table reaches 90 degrees, a sensing signal is sent out, and the test group that receives the signal drives the sensing group to perform a mobile test; S4, after the test is completed, the driving component continues to drive the linkage component, causing the movable component to rotate in the opposite direction along the arc guide rail, thereby driving the storage table to reset. At this time, the adjustment component that has rotated one circle can unlock the clamping component, drive the clamping plate away from the main board and lift the main board upwards, and use the grab arm to grab the main board again and place it on the next conveyor belt.

[0016] Furthermore, starting the driving component in S3 includes driving the linkage component and the adjustment component in sequence. A sensor is provided on the storage table. When the storage table moves to ninety degrees, the test group triggers the switch after receiving the signal, thereby realizing the up, down, left and right movement of the sensor group.

[0017] Compared with the prior art, the present invention has the following beneficial effects: 1. The clamping assembly can not only automatically fix the mainboard without manual twisting, but also lift the mainboard upward while moving the clamping plates on both sides away from the mainboard to cancel the fixation, thereby facilitating the replacement of the mainboard.

[0018] 2. Through the set driving assembly and linkage assembly, the movable assembly can be driven to rotate on the arc guide rail, thereby driving the storage table to rotate, realizing the angle adjustment of the mainboard, thereby completing the plug-in slot test on the side of the mainboard.

[0019] 3. By setting up an adjusting component for use in conjunction, the adjusting component can be synchronously driven to rotate when the driving component is started, thereby driving the clamping component to start. Since the adjusting component has extensibility, the linkage component has completed its movement when the clamping component is started, and the storage table has been reset at this time, so that the start of the clamping component does not affect the operation of the storage plate.

[0022] In order to make the above-mentioned objects, features and advantages of the present invention more obvious and easy to understand, the specific implementation methods of the present invention are described in detail below in conjunction with the accompanying drawings.

[0023] Example 1, reference Figure 1-Figure 4, which is the first embodiment of the present invention, provides an online rapid testing device for a microcomputer motherboard, comprising a test bench 1, a gripping arm 11 movably mounted at the corners of both sides of the test bench 1, a test group 12 fixedly mounted on one side of the test bench 1, a sensing group 13 mounted on the test group 12, a storage table 14 movably mounted at the center above the test bench 1, and also comprising a clamping assembly 2 mounted inside the storage table 14, an adjusting assembly 3 movably mounted on the test bench 1, an arc guide rail 4 fixedly mounted on both sides of the test bench 1, the two arc guide rails 4 are respectively located on both sides of the storage table 14, a linkage assembly 5 movably mounted on one side of the test bench 1, the linkage assembly 5 is located on one side of the arc guide rail 4 close to the storage table 14, and a driving assembly 6 arranged on the test bench 1, the driving assembly 6 is transmission-connected to the linkage assembly 5; the clamping assembly 2 comprises an installation cavity 201 opened inside the storage table 14, an active groove 202 symmetrically opened above the storage table 14 and communicating with the installation cavity 201, and a sliding bar symmetrically and movably mounted in the installation cavity 201 21, a telescopic rod 22 fixedly mounted on one side of the slide bar 21, a spring 23 sleeved on the telescopic rod 22, two ends of the spring 23 respectively connected to the inner wall of the installation cavity 201 and the slide bar 21, a push rod 24 mounted on the other side of the slide bar 21, a fitting block 25 fixedly mounted on the other end of the push rod 24 away from the slide bar 21, a support rod 26 installed in the center of the storage table 14, a round table 27 fixedly arranged near the bottom of the support rod 26, the round table 27 is located between the two fitting blocks 25 and fits with the fitting blocks 25 For use in conjunction with the above; it also includes a clamping plate 141 symmetrically and movably installed above the storage table 14, the clamping component 2 is fixedly connected to the clamping plate 141, and the clamping component 2 drives the clamping plate 141 to move on the upper surface of the storage table 14; the storage table 14 is located in an I-shaped shape, and the adjustment component 3 is located at the bottom of the support rod 26; a movable component 41 is movably installed on the arc guide rail 4, and the arc guide rail 4 is fixedly connected to the storage table 14 through the movable component 41, and the other end of the movable component 41 is fixedly connected to the linkage component 5.

[0024] Specifically, before testing the mainboard, the mainboard is placed in the center of the storage table 14 using the gripping arm 11 in advance, and the telescopic rod 22 and the spring 23 are no longer limited by pressing the support rod 26 and the round table 27 downward. The slide bar 21 is driven to move under the action of the elastic force of the spring 23, thereby driving the two clamping plates 141 to move relative to each other, thereby achieving the limiting and fixing effect on the mainboard, and avoiding the mainboard from losing the limit and moving or even detaching during the test. The linkage component 5 and the adjustment component 3 are driven to start at the same time by starting the driving component 6. Because the movable component 41 is installed on the arc track 4, and the two ends are fixedly connected to the linkage component 5 and the storage table 14 respectively, after the linkage component 5 is started, it can drive the movable component 41 to rotate on the arc track 4, thereby driving the storage table 14 to rotate along the same trajectory, thereby realizing the test of the plug-in slot on the side of the mainboard. Because the adjustment component 3 is located at the bottom of the support rod 26 and the storage table 14 is I-shaped, the rotating storage table 14 will not be limited by the adjustment component 3.

[0025] Reference Fig. 9 The adjustment assembly 3 includes a bent rod 31 fixedly mounted on the test bench 1, a protrusion 32 rotatably mounted on the end of the bent rod 31, a toothed plate 33 fixedly mounted on one side of the protrusion 32, a straight rod 34 rotatably mounted on the test bench 1, and a toothed disc 35 fixedly mounted on the top of the straight rod 34.

[0026] Specifically, when the driving assembly 6 is started, it can drive the toothed disc 35 to rotate, thereby driving the toothed plate 33 and the protrusion 32 to rotate. When the protrusion of the protrusion 32 rotates to the bottom of the support rod 26, it pushes the support rod 26 upward, thereby starting the clamping assembly 2 so that the clamping plate 141 is away from the main board and can lift the main board upward, making it convenient to take the main board later.

[0027] Reference Fig. 9 Three groups of tooth blocks are installed on the tooth plate 33 in an array circumference, and a group of tooth grooves are opened on the tooth disc 35. The tooth grooves on the tooth disc 35 mesh with the tooth blocks on the tooth plate 33 accordingly.

[0028] Specifically, since the tooth plate 33 array has three groups of tooth blocks, and the tooth disc 35 is provided with a group of matching tooth grooves, when the drive component 6 is started, it drives the tooth disc 35 to rotate. After the tooth disc 35 rotates one circle, the tooth groove reaches the tooth block on the tooth plate 33 and drives the tooth plate 33 to rotate after engagement. After disengagement, the tooth plate 33 no longer rotates. Therefore, a certain delay is required after the drive component 6 is started before the tooth plate 33 can be started to rotate, and it also takes a certain amount of time for the protrusion 32 to rotate to the bottom of the support rod 26. Therefore, during this time, the linkage component 5 can complete the repeated movement of the storage table 14, thereby avoiding the situation where the clamping component 2 is triggered to start while the storage table 14 is rotating, thereby preventing the main board from falling off.

[0029] Reference Figure 4 The top of the support rod 26 passes through the storage platform 14 and a storage plate 28 is fixedly installed on the top.

[0030] Specifically, after the mainboard is placed on the storage plate 28, the mainboard drives the storage plate 28 to move downward, thereby pushing the support rod 26 downward, which can trigger the clamping assembly 2 to start, thereby driving the clamping plates 141 on both sides to approach each other until the mainboard is clamped and fixed.

[0031] Reference Figure 1-Figure 7 The driving component 6 includes a mounting groove 101 opened inside the test bench 1, a rectangular hole 102 opened on the test bench 1, the rectangular hole 102 is connected to the mounting groove 101, a driving motor 61 installed inside the mounting groove 101, a first bevel gear 62 fixedly installed at the output end of the driving motor 61, a second bevel gear 63 movably installed in the rectangular hole 102, the second bevel gear 63 is meshed and connected with the linkage component 5, and a third bevel gear 64 movably installed at the top of the mounting groove 101; the straight rod 34 penetrates the test bench 1 and extends into the mounting groove 101, and the top of the third bevel gear 64 is fixedly connected to the bottom of the straight rod 34.

[0032] Specifically, by starting the driving motor 61, the first bevel gear 62 is driven to rotate, thereby driving the second bevel gear 63 and the third bevel gear 64 to rotate respectively. The rotating second bevel gear 63 can drive the linkage assembly 5 to start, thereby realizing the rotation of the storage table 14. The top of the rotating third bevel gear 64 is fixedly connected to the straight rod 34 to start the adjustment assembly 3.

[0033] Example 2, reference Figure 1-Figure 10 , which is the second embodiment of the present invention. This embodiment is different from the first embodiment in that: the linkage assembly 5 includes an L-plate 51 fixedly installed on one side of the test bench 1, a connecting rod 52 penetrating the L-plate 51, a fourth bevel gear 53 and a movable member 54 respectively connected to both ends of the connecting rod 52, a rack 55 movably connected to the movable member 54, a transmission wheel 56 meshing with the rack 55, a connecting rod 57 is installed on the side of the transmission wheel 56 away from the fourth bevel gear 53, and the transmission wheel 56 is connected to the movable assembly 41 through the connecting rod 57; a limiting member 571 is installed at one end of the connecting rod 57 close to the transmission wheel 56, and one end of the rack 55 is installed above the transmission wheel 56 through the limiting member 571 and meshes with the transmission wheel 56.

[0034] Specifically, when the driving assembly 6 is started, it drives the fourth bevel gear 53 to rotate, thereby driving the connecting rod 52 to rotate, and under the action of the movable part 54, drives the rack 55 to rotate. Because one end of the rack 55 is limited above the transmission wheel 56 and meshes with the transmission wheel 56, it drives the transmission wheel 56 to reciprocate, which limits the rotation of the transmission wheel 56 and prevents the transmission wheel 56 from rotating in the opposite direction due to external force. Because the transmission wheel 56 is connected to the movable assembly 41 through the connecting rod 57, it can drive the movable assembly 41 to reciprocate in the same direction.

[0035] Reference Figure 8 The movable component 41 includes an arc hole 401 passing through the arc guide rail 4, a slider 411 slidably installed on the arc guide rail 4, a vertical rod 412 passing through the arc hole 401 and fixedly connected to the slider 411, a cross bar 413 fixed to the top of the vertical rod 412 and a connecting block 414 at the bottom; the other end of the cross bar 413 is fixedly connected to the storage table 14 through a mounting piece, and the connecting block 414 is fixedly connected to the connecting rod 57.

[0036] Specifically, because the connecting block 414 is connected to the transmission wheel 56 through the connecting rod 57, the connecting block 414 and the vertical rod 412 are driven to rotate when the transmission wheel 56 rotates. Because the vertical rod 412 and the slider 411 are fixedly connected, the slider 411 can be driven to move back and forth in the same direction on the arc guide rail 4, thereby driving the storage table 14 to rotate under the connection of the cross bar 413. When the storage table 14 rotates to 90 degrees, the test group 12 is triggered by the induction system to drive the induction group 13 to test the side of the mainboard on the storage table 14. The rest of the structure is the same as that of Example 1.

[0037] Example 3, reference Figure 1-Figure 10 , as the third embodiment of the present invention, provides: a microcomputer motherboard online rapid testing method, comprising the following steps, S1, when placing the mainboard, the gripping arm 11 places the mainboard on the placement plate 28, so that the placement plate 28 presses the clamping assembly 2 downward, thereby driving the clamping plates 141 on both sides to move toward the middle. At this time, the mainboard is clamped and fixed by the clamping plates 141, and the adjusting assembly 3 drives the clamping assembly 2 to reset under the action of the driving assembly 6.

[0038] S2, when testing the upper surface of the mainboard, the testing group 12 drives the sensing group 13 to move up, down, left, and right, so that the sensing test can be performed on the mainboards at different positions.

[0039] S3, when testing the side surface of the mainboard, the driving component 6 drives the linkage component 5 to be linked, so that the movable component 41 can perform guiding activities on the arc guide rail 4, thereby realizing the guided rotation of the storage table 14. When the rotation angle of the storage table 14 reaches ninety degrees, a sensing signal is sent out, and the test group 12 that receives the signal drives the sensing group 13 to perform a mobile test.

[0040] S4, after the test is completed, the driving component 6 continues to drive the linkage component 5, so that the movable component 41 rotates in the opposite direction along the arc guide rail 4, thereby driving the storage table 14 to reset. At this time, the adjustment component 3 that has rotated one circle can unlock the clamping component 2, drive the clamping plate 141 away from the main board and lift the main board upward, making it convenient to use the grab arm 11 to pick up the main board.

[0041] S5, starting the driving component 6 in S3 includes driving the linkage component 5 and the adjustment component 3 in sequence. A sensor is set on the storage table 14. When the storage table 14 moves to ninety degrees, the test group 12 triggers the switch after receiving the signal, thereby realizing the up, down, left and right movement of the sensing group 13.

[0042] In summary, the working principle of the present invention is as follows: the motherboard transported from the conveyor belt is placed on the storage plate 28 in the middle of the storage table 14 by the grab arm 11 in advance, and the motherboard drives the storage plate 28 to descend, and in the process of descending, the support rod 26 and the round table 27 are pushed downward, at this time, the fitting blocks 25 on both sides are no longer limited by the round table 27, and the telescopic rod 22 and the slide bar 21 are driven to move under the action of the spring 23, so that the clamping plates 141 on both sides move relatively to clamp the motherboard, and after being fixed, the test group 12 is passed through the belt After the motion sensing group 13 moves, the upper surface of the mainboard is tested. When the side surface of the mainboard is tested, the first bevel gear 62 is driven to rotate by starting the driving motor 61, thereby driving the second bevel gear 63 to rotate, and the fourth bevel gear 53 is driven to rotate under the action of gear meshing, and the rack 55 is driven to rotate under the action of the connecting rod 52 and the movable part 54, thereby driving the transmission wheel 56 located at the bottom of the rack 55 and meshing with the rack 55 to reciprocate. Because the two ends of the connecting rod 57 are respectively connected to the transmission wheel 56 and the connecting rod 57, The block 414 can drive the connecting block 414 to rotate, thereby driving the vertical rod 412 and the slider 411 to rotate on the arc guide rail 4, so as to realize the rotation of the storage platform 14. When the storage platform 14 rotates to ninety degrees, the sensor on the storage platform 14 sends out a sensing signal. The test group 12 that receives the signal continues to drive the sensing group 13 to test the main board on the storage platform 14. After the test is completed, the drive motor 61 is started again ... The rod 412 and the slider 411 rotate in opposite directions on the arc guide rail 4, thereby resetting the storage table 14. The second bevel gear 63 that rotates at the same time also drives the third bevel gear 64 to rotate, driving the straight rod 34 and the toothed disc 35 to rotate. The tooth grooves on the toothed disc 35 cooperate with the 33 tooth blocks on the toothed plate to indirectly push the support rod 26 upward, so that the clamping plates 141 on both sides are away from the main board and the main board is lifted upward. At this time, the grab arm 11 picks up the main board and places it on the next conveyor belt.

[0043] It should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention rather than to limit it. Although the present invention has been described in detail with reference to the preferred embodiments, those skilled in the art should understand that the technical solutions of the present invention may be modified or replaced by equivalents without departing from the spirit and scope of the technical solutions of the present invention, which should all be included in the scope of the claims of the present invention.
