Description

Technical Field

[0001] The present invention relates to the technical field of motherboard testing devices, and particularly to a serial high-order hard disk architecture (SATA) interface function testing device for a motherboard. Background Art

[0002] The main content of the SATA interface function test for a motherboard is to connect to the SATA interface and detect whether there is memory. There are relevant records in the prior art. The prior art, 200410051258.0, a serial high-order hard disk architecture (SATA) interface function testing device for a motherboard, is used to test the SATA interface function of the motherboard. The serial high-order hard disk architecture interface function testing device includes a flash memory chip with a certain storage capacity, a detection chip connected to the flash memory chip for converting flash memory signals into IDE signals, and a signal conversion chip connected to the detection chip for converting IDE signals into SATA signals. During the test, the motherboard receives the SATA signals sent by the SATA interface function testing device and identifies that the SATA interface function testing device has a certain storage capacity according to the information of the signals, thereby completing the detection of the SATA interface function of the motherboard.

[0003] This prior art provides a mature detection idea and a feasible direction for actual operation. However, during the factory production process, more modifications are required to adapt to large-scale detection. In reality, a manipulator is used in cooperation with a CDD industrial camera to implement the connector plugging and unplugging process through an algorithm, but this method is costly. Especially during large-scale production, a batch of manipulators is extremely expensive.

[0004] During the R & D process, engineers use a lifting structure to drive a batch of plugs to be inserted into the SATA interfaces of the motherboard for testing. According to actual production needs, multiple motherboards can be detected at a time, with high efficiency and low cost. Each motherboard has multiple SATA interfaces. After the plug is inserted into the SATA interface and then pulled out, a relatively large force is required, and a pressing operation is needed to release the buckle. The action is relatively complex. The motherboard is light in weight, and it is not easy to pull out the existing plugs, so adjustments are required.

[0005] Selecting to use a manipulator in cooperation can achieve a fast loading and unloading process. However, the cost is high, the single test volume is limited by the working efficiency of the manipulator, and the SATA interface connection and disconnection processes are also relatively complex, affecting the test efficiency. Summary of the Invention

[0006] The purpose of the present invention is to provide a serial high-order hard disk architecture (SATA) interface function testing device for a motherboard to solve the problems raised in the above background art.

[0013] Further, the testing device further includes a touch limiting structure, which includes a touch member and a positioning frame. The touch member is arranged on the top surface of the mold and is located on one side of the receiving groove. The touch member includes a column, a slider, a rack, an interference block, a limiting block, a mounting sleeve, a rotating shaft, a semi-positioning structure, and a touch rod. The column is arranged on one side of the receiving groove, and a through groove is formed at the top of the column. The slider is slidably arranged in the through groove. The rotating shaft is rotatably arranged on the slider. The semi-positioning structure is arranged on one side of the column. The semi-positioning structure includes a mounting block, a semi-positioning rod, and a third spring. A hemispherical hole is formed on the side surface of the rotating shaft. The mounting block is arranged on the side surface of the column above the rotating shaft, and a mounting hole is formed at the bottom of the mounting block.

When the upper rod is arranged vertically upward, the bottom end of the semi-positioning rod is located in the hemispherical hole, the interference block supports on the teeth of the rack, and the positioning rod is located above the positioning hole. When the upper rod is arranged vertically downward, the bottom end of the semi-positioning rod disengages from the hemispherical hole, the mounting sleeve rotates 180°, the interference block disengages from the cooperation with the teeth of the rack, the slider descends, the cross bar descends, and the positioning rod is inserted into the positioning hole.

The cylinder drives the lifting frame to descend, and the lifting pipe assembly descends and inserts into the SATA interface. The elastic force of the first spring pushes the connector into the SATA interface, and the test terminal conducts a test. After the test is completed, the lifting frame is still pushed to descend, and then the sliding rod abuts against the main board. On the one hand, the sliding rod presses the buckle on the side of the connector to unlock the buckle. On the other hand, it realizes abutting against the main board, and finally the limiting ball is located in the limiting hole. Finally, the cylinder drives the lifting frame to rise, the connector disengages from the SATA interface, and the mold slides downward to complete the detection. The operation is convenient and the cost is low. BRIEF DESCRIPTION OF THE DRAWINGS

Detailed implementation mode

[0027] The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0028] Embodiment 1:

[0029] The present invention provides a serial high - order hard disk architecture SATA interface function test device for a motherboard as shown in the accompanying drawings, including a test terminal 1, a bracket 2, and a connector 3. The connector 3 is connected to the test terminal 1 through a data cable 4. The test terminal 1 is arranged on the bracket 2. The test terminal 1 can detect the quality of the corresponding SATA interface of the motherboard, which is the principle of the prior art. The test device further includes a mold 5, a cylinder 6, a lifting frame 7, a conveying device 8, a bottom bracket 9, and a lifting pipe assembly 10, wherein:

[0030] The molds 5 are arranged on the conveying rollers of the conveying device 8 at equal intervals. Multiple rows of receiving grooves for placing main boards are provided on the molds 5. The receiving grooves in each row are staggered along the conveying direction of the conveying device. During actual production, a manipulator can be used in cooperation with a CDD camera to grab the mold 5 onto the conveying roller. The position of the mold 5 is relatively fixed, and multiple main boards can be set on the mold at one time. Of course, the position can also be marked on the conveying roller and manually transported. The meaning of the staggering of the receiving grooves is that the SATA interfaces on the main boards arranged in the receiving grooves are staggered when viewed in the conveying direction of the conveying device. More precisely, the purpose of this staggering method is that in subsequent work, each set of lifting tube assemblies is correspondingly arranged with each receiving groove, and each lifting tube assembly is correspondingly provided with a touch limiting structure, and the touch limiting structure does not interfere with other lifting tube assemblies;

[0031] The lifting frame 7 is arranged on the bracket 2 in a liftable manner;

[0032] The cylinder 6 is arranged on the bracket 2, and the piston rod is fixedly connected to the lifting frame 7;

[0033] The bottom bracket 9 is arranged on both sides of the conveying device 8 and is located directly below the lifting frame 7;

[0034] The lifting tube assembly 10 includes a pipe fitting 11, a first spring 12, a second spring 13, a mounting block 14, a sliding rod 15, and a touch rod 16. The pipe fitting 11 is fixedly arranged at the bottom of the lifting frame 7. The mounting block 14 is arranged on the inner side surface of the inner cavity of the pipe fitting 11. The sliding rod 15 is arranged in the through hole of the mounting block 14 in a vertically slidable manner. A connecting block 17 is arranged on the side surface of the joint 3. The connecting block 17 is arranged on the sliding rod 15 in a vertically slidable manner. The first spring 12 and the second spring 13 are respectively sleeved on the sliding rod 15 above the connecting block 17 and on the sliding rod 15 below the connecting block 17. The elastic coefficient of the first spring 12 is greater than that of the second spring 13. A chute 18 is opened on one side of the pipe fitting 11. The touch rod 16 is fixedly connected to one side of the top end of the sliding rod 15 and passes through the chute 18. Each receiving groove is correspondingly provided with a lifting tube assembly. When the sliding rod 15 descends, it can press the buckle 19 of the joint 3. A limiting hole 20 is opened on the outer side surface of the connecting block 17, and a limiting ball 21 is arranged on the side surface of the pipe fitting 11. The limiting ball 21 can be received in the limiting hole 20.

[0035] Working principle of the lifting tube assembly 10:

[0036] When the mold 5 is under the lifting frame 7, the air cylinder 6 is opened at this time, the lifting frame 7 descends, the pipe fitting 11 descends, and the connector 3 first contacts the SATA interface of the main board. At the initial stage when the connector 3 is first connected to the SATA interface, the resistance is the greatest. At this time, as the lifting frame 7 continues to descend and the connector 3 abuts against the SATA interface in the early stage, the first spring 12 is compressed. At this time, the elastic force of the first spring 12 continuously increases and finally breaks through the resistance at the initial stage of the docking between the connector 3 and the SATA interface. The connector 3 enters the SATA interface, and the resistance is greatly reduced. At this time, the elastic force of the first spring 12 is too large. The provided second spring 13 can bear this part of the elastic force, reduce the driving force of the connector 3 sliding in the SATA interface, and avoid damaging the SATA interface. After the connector completes the connection with the SATA interface, the test terminal 1 starts to work for testing and records the test results.

[0037] After the test is completed, considering the problems that the buckle 19 needs to be unfastened, the resistance between the connector 3 and the SATA interface is relatively large, and the weight of the main board itself is insufficient, the limiting ball 21 and the limiting hole 20 are provided in this embodiment. First, after the test is completed, the air cylinder 6 continues to descend. At this time, both the first spring 12 and the second spring 13 are compressed, and the pipe fitting 11 descends, and the slide bar 15 descends. Finally, the limiting ball 21 is stuck in the limiting hole 20, and the pipe fitting 11 and the slide bar 15 stop descending. At this time, the descended slide bar 15 presses the buckle to achieve the purpose of unlocking. At the same time, the bottom of the slide bar 15 abuts against the main board to apply pressure. It is worth reminding that the trigger rod 16 can abut against the top of the chute 18 to achieve the purpose of restricting the position of the slide bar 15. After the slide bar 15 unlocks the buckle 19, it then descends, solving the problem of relatively large resistance at the initial stage of unlocking between the connector 3 and the SATA interface. After the limiting ball 21 and the limiting hole 20 are connected, the pipe fitting 11 can drive the connector 3 to lift and lower. In this state, the air cylinder 6 retracts, the lifting frame 7 rises, the connector 3 is completely separated from the SATA interface, and the mold 5 can then run to the next step.

[0038] Embodiment 2:

[0039] During actual production, Embodiment 1 can basically achieve detection, but there are the following problems

[0040] 1. The mold 5 needs to be positioned on the conveying device 8.

[0041] 2. After each test is completed, the limiting ball 21 is located in the limiting hole 20. When testing next time, it is necessary to push the pipe fitting 11 to separate the limiting ball 21 from the limiting hole 20.

[0042] To solve the above problems, this embodiment further includes a touch limit structure. The touch limit structure includes a touch member 22 and a positioning frame 23. The touch member 22 is arranged on the top surface of the mold 5 and is located on one side of the receiving groove. The touch member 22 includes a column 24, a slider 25, a rack 26, an interference block 27, a limit block 28, a mounting sleeve 29, a rotating shaft 30, a semi-positioning structure 31 and a touch rod 32. The column 24 is arranged on one side of the receiving groove, and a through groove 33 is opened at the top of the column 24. The slider 25 is slidably arranged in the through groove 33. The rotating shaft 30 is rotatably arranged on the slider 25. The semi-positioning structure 31 is arranged on one side of the column 24. The semi-positioning structure 31 includes a mounting block 34, a semi-positioning rod 35 and a third spring 36. A hemispherical hole 37 is opened on the side surface of the rotating shaft 30. The mounting block 34 is arranged on the side surface of the column 24 above the rotating shaft 30, and a mounting hole 38 is opened at the bottom of the mounting block 34. The semi-positioning rod 35 is slidably arranged in the mounting hole 38. The third spring 36 is arranged in a compressed state on the bottom surface of the mounting hole 38 and abuts against the top of the semi-positioning rod 35. The bottom end of the semi-positioning rod 35 is hemispherical and is slidably arranged in the hemispherical hole 37. The other end of the rotating shaft 30 is fixedly provided with a mounting sleeve 29. The touch rod 32 includes an upper rod 39 fixedly arranged on the side surface of the mounting sleeve 29 and a lower rod 40 symmetrically arranged with the upper rod 39 on the other side of the mounting sleeve 29. A counterweight ball 41 is arranged in the middle of the upper rod 39. An arc-shaped hook member 42 is arranged at the bottom of the lower rod 40. The rack 26 is arranged on both sides of the through groove 33 and avoids the slider 25. The teeth of the rack 26 are structured such that the upper side is a right-angled side and the lower side is an inclined surface. One end of the interference block 27 is rotatably arranged on the side surface of the rotating shaft 30, and an avoidance notch 43 is opened at the upper part of the outer end of the interference block 27. The limit block 28 is arranged on the side surface of the rotating shaft 30 and interferes with the lower part of the inner end of the interference block 27. The positioning frame 23 includes a cross bar 44 and a positioning rod 45. A positioning hole 46 is opened on the bottom bracket 9. A cross bar 44 is arranged between the sliders 25 of each row of touch members 22 and a cross bar 44 is arranged on the outer side surface of the outermost slider 25. The positioning rod 45 is arranged downward on the side surface of the cross bar 44 on the outer side surface of the outermost slider 25, and the positioning rod 45 is inserted into the positioning hole 46. When the upper rod 39 is arranged vertically upward, the bottom end of the semi-positioning rod 35 is located in the hemispherical hole 37, the interference block 27 supports on the teeth of the rack 26, and the positioning rod 45 is located above the positioning hole 46. When the upper rod 39 is arranged vertically downward, the bottom end of the semi-positioning rod 35 disengages from the hemispherical hole 37, the mounting sleeve 29 rotates 180°, the interference block 27 disengages from the engagement with the teeth of the rack 26, the slider 25 descends, the cross bar 44 descends, and the positioning rod 45 is inserted into the positioning hole 46.

[0043] Working principle of the touch limit structure:

[0044] The conveying device 8 drives the mold 5 to move forward. At this time, the upper rod 39 is vertically upward. The upper rod 39 on one side of each receiving groove can only contact the touch rod 16 above the receiving groove correspondingly. After the upper rod 39 in the front row contacts the touch rod 16 in the front row, the advancing mold 5 drives the upper rod 39 to rotate. Driven by the counterweight ball 41, the upper rod 39 rotates downward by 180°. The bottom end of the semi-positioning rod 35 disengages from the hemispherical hole 37. At this time, the interference block 27 rotates by 180°, the positioning rod 45 rotates by 180°. The interference block 27 disengages from the teeth of the rack 26. Under gravity, the slider 25 descends. The arc-shaped hook 42 of the lower rod 40 hangs on the touch rod 16. When the slider 25 descends, it drives the touch rod 16 to descend, the limiting ball 21 and the limiting hole 20 are disengaged. Finally, the positioning rod 45 is inserted into the positioning hole 46, while restricting the mold 5 from moving forward, the joint 3 is lowered, waiting for the joint 3 to be inserted into the SATA interface for detection.

[0045] After the detection is completed, the cylinder 6 drives the lifting frame 7 to rise, the pipe fitting 11 rises, the limiting ball 21 is stuck into the limiting hole 20, the pipe fitting 11 continues to rise, driving the lower rod 40 to rise, and then the positioning rod 45 disengages from the positioning hole 46. The conveying device 8 drives the mold 5 to move forward. On the one hand, the touch rod member 32 will not contact other touch rods 16. On the other hand, the arc-shaped hook 42 can be disengaged from the touch rod 16. Under its own weight, the positioning rod 45 abuts against the bottom bracket 9. The positioning holes 46 are arranged staggeredly to prevent the positioning rod 45 from being inserted into other positioning holes 46 during the forward movement.

[0046] Embodiment 3:

[0047] According to the solution of Embodiment 2, after the upper rod 39 in the front row contacts the touch rod 16, the actions that occur need time to complete. To achieve this action, a ring structure 47 is provided at the top of the upper rod 39 of the touch rod member 32 at the frontmost side, and the middle part of the side of the ring structure 47 contacts the touch rod 16.

[0048] Finally, it should be noted that the above are only the preferred embodiments of the present invention and are not used to limit the present invention. Although the present invention has been described in detail with reference to the foregoing embodiments, for those skilled in the art, they can still modify the technical solutions described in the foregoing embodiments, or perform equivalent replacements for some of the technical features. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
