Detailed Implementation

[0029] The following detailed, non-limiting description of the technical solution of the present invention, in conjunction with preferred embodiments and accompanying drawings, is provided. Obviously, the described embodiments are merely some, not all, of the embodiments of the present invention. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without inventive effort are within the scope of protection of the present invention.

[0030] Please see Figure 1-8 The present invention provides a technical solution: a servo-driven DIMM automatic insertion and removal module, which is installed on a testing table. Specifically, it includes a support frame 1, which is a hollow convex shape. The two sides of the support frame 1 are fixedly installed on the upper ends of the testing table by bolts. The top of the support frame 1 is fixedly connected to a control board 2 by a rod. The control board 2 is used for monitoring the sensing data and intelligently executing the module insertion and removal process.

[0031] See Figure 1The module includes a servo drive component 3, used to drive the clamped memory module to move up and down during the insertion and removal process; the output end of the servo drive component 3 is connected to a first downward component 6, used for the first stage of downward movement and the final upward movement; a support frame 1 is located directly below the servo drive component 3 and a fixing component 5 is installed, which serves as a connection and support during the insertion and removal process; a second downward component 8 is arranged between the fixing component 5 and the first downward component 6, which is used for the second stage of downward movement and the initial upward movement; several sets of claw components 7 are rotatably connected inside the fixing component 5 to assist in the stable insertion and removal of the memory module, with two claw components 7 arranged opposite each other on both sides of the fixing component 5; a clamping component 9 is arranged below the second downward component 8 to clamp the memory module; a testing platform is located directly below several memory modules and has corresponding insertion and removal slots 10 for testing the performance of the memory modules after insertion and power-on; through the above component arrangement, the module can realize the performance testing of multiple sets of memory modules after insertion.

[0032] Further, see Figure 1 The servo drive assembly 3 includes a drive motor 31, a gearbox 32, a drive shaft 33, and a nut block 34. The drive motor 31 is mounted on the lower side of the support frame 1. The gearbox 32 contains multiple meshing gears. The output end of the drive motor 31 is connected to the input end of the gearbox 32, and the output end of the gearbox 32 is connected to the drive shaft 33. The drive motor 31 is electrically connected to the control board 2 via wires. After the drive motor 31 is powered on, its output end controls the drive shaft 33 to rotate in both directions through the gearbox 32, thereby driving the first lowering assembly 6 and the second lowering assembly 8 to move down and up. The speed of the up and down movement is determined by the output power of the drive motor 31. In addition, the drive shaft 33 is rotatably connected to the nut block 34. The nut block 34 is longitudinally locked, and moves up and down synchronously when the drive shaft 33 rotates.

[0033] Furthermore, the fixing component 5 includes a locking block 51, a multi-shaped frame 52, a sliding groove 53, a fixing shaft 54, and a sensing elastic element 55. The locking block 51 adopts an L-shaped design and is fixedly connected to the lower surface of the support frame 1 by bolts. The locking block 51 is fixed to the top two ends of the multi-shaped frame 52 respectively. The fixing shaft 54 ​​passes through and is fixed to the inward sides of the multi-shaped frame 52 respectively. The sensing elastic element 55 is set on the outer surface of the fixing shaft 54. The sliding groove 53 is opened at the bottom of both sides of the multi-shaped frame 52 to synchronously guide the rotation of the claw assembly 7 and synchronize with the insertion and removal action of the memory module. The fixing component 5 remains fixed in the automatic insertion and removal action of the memory module of the whole module, thus ensuring the stability of the overall action and connection state in advance.

[0034] The sensing elastic element 55 includes a spring and a strain gauge fixedly connected to the bottom of the spring. The strain gauge is embedded in the frame of the multi-type frame 52 at the bottom of the spring. Specifically, the spring is wound around the outer surface of the fixed shaft 54 ​​to bear the pressure generated during the insertion process. The spring deformation is positively correlated with the pressure. The strain gauge is located below the spring and senses the spring deformation through the pressure it bears. The deformation causes a change in the resistance value of the strain gauge. The change in resistance is converted into an electrical signal and transmitted to the control board 2. Under the action of the control board 2, the force data is output. It should also be noted that the strain gauge can also be replaced by a strain gauge structure, which will not be elaborated here.

[0035] In summary, the sensing elastic element 55 is connected to the control board 2 via signal transmission to transmit the force data of the sensing elastic element 55 and monitor whether its movement is balanced and stable.

[0036] Further, see Figure 1 and Figure 6 The first downward moving component 6 is used for the first stage of the insertion process. The first downward moving component 6 includes a downward moving rod 61, a first downward moving frame 62, a vibration sensor 63, and a pressing rod 64. The downward moving rod 61 is fixedly connected to the bottom surface of the nut block 34 at its top through a plate. The surface of the downward moving rod 61 is slidably connected to the top of the multi-type frame 52. For example, a sleeve is installed at the position where the top of the multi-type frame 52 is slidably connected to the downward moving rod 61 to facilitate the downward sliding of the downward moving rod 61. The bottom of the downward moving rod 61 is fixedly connected to the first downward moving frame 62. Wedge-shaped protrusions are fixedly connected to both sides of the first downward moving frame 62 to control the position of the claw assembly 7. The middle part of the first downward moving frame 62 is fixedly installed with the vibration sensor 63. The vibration sensor 63 is signal-connected to the control board 2 to monitor the force and vibration of the memory module during insertion. The lower surface of the vibration sensor 63 is fixed to the pressing rod 64 to determine the position of the first stage of the insertion process.

[0037] Further, see Figure 2 , Figures 6-8 The second downward moving component 8 is used to perform the second stage insertion process to complete the insertion process between the memory module and the insertion slot block 10. The second downward moving component 8 includes a second downward moving frame 81, a displacement plate 82, a central pressing post 83 and a central pressing bead 84. The second downward moving frame 81 is connected through the fixed shaft 54, and the sensing elastic element 55 is supported and connected to the second downward moving frame 81. The displacement plate 82 is fixed above one side of the second downward moving frame 81 to assist in displacement monitoring. The central pressing post 83 is located directly below the pressing rod 64. The central pressing post 83 is fixedly installed in the lower middle of the second downward moving frame 81. The upper surface of the central pressing post 83 and the lower surface of the pressing rod 64 are respectively provided with positive and negative poles. When the central pressing post 83 contacts the pressing rod 64, the contact state can be indicated by the circuit signal.

[0038] In addition, the second lower moving frame 81 is provided with side pressure columns on both sides of the lower part of the central pressure column 83. As can be seen in the figure, the central pressure bead 84 is installed at the bottom of the central pressure column 83, and the bottom of the side pressure columns on both sides is also provided with side pressure beads. The central pressure bead 84 and the side pressure beads are matched with the clamping assembly 9, so that the clamping assembly 9 has a certain floating performance when driving the memory module to be inserted.

[0039] Among them, the upper two sides of the second lower moving frame 81 are respectively provided with active limiting surfaces 85, which are used to guide the opening of the claw assembly 7 in the second stage of the insertion process.

[0040] See Figure 3 The pawl assembly 7 includes a pawl holder 71, a roller 72, a sliding roller 73, and a pawl 74. The top of the pawl assembly 7 has an annular groove, which is connected to the second lower moving frame 81 via a rod. The roller 72 is slidably supported inside the sliding groove 53. The pawl 74 is fixedly connected to the bottom of the pawl holder 71. The roller 72 is connected to the crank rod end extending from the pawl holder 71 via a central shaft bearing. The surfaces of the roller 72 are in contact with the outer walls of both sides of the second lower moving frame 81. The structural design of the pawl assembly 7 is a disclosed technology and will not be described in detail here. In addition, the top of the pawl holder 71 has a passive limiting surface 75 that cooperates with the active limiting surface 85 to realize the change of the position and angle of the pawl 74.

[0041] See Figure 4 and Figure 5 The clamping assembly 9 includes a floating block 91, a central pressing groove 92, a side pressing groove 93, and a locking block 94. The locking blocks 94 are respectively installed on both sides of the floating block 91. The locking blocks 94 are used to stably clamp the memory module. The central pressing groove 92 is set to correspond to the central pressing bead 84. The side pressing groove 93 is set to match the side pressing bead, that is, it is set in a hemispherical shape, which facilitates positioning and locking. The central pressing groove 92 does not have this setting. The clamping assembly 9 has a certain floating gap when pressing down the memory module, which reduces the damage rate of the memory module pins during insertion.

[0042] It should be noted that, in order to cooperate with the up and down movement of the displacement plate 82, a displacement detection component 4 is provided on the side of the support frame 1 near the displacement plate 82. The displacement detection component 4 includes a sensing side plate 41 and a ranging sensing block 42 installed on the sensing side plate 41. The number of ranging sensing blocks 42 can be set to a certain number. A certain number of slots can be opened on the displacement plate 82. The ranging sensing block 42 determines the moving position of the displacement plate 82 by whether infrared light is received and checks it against the insertion and removal status to ensure the accuracy of the position movement. If an inconsistency occurs, a back-end alarm operation is performed to replace and correct the module, improve the accuracy of use, and ensure the effectiveness of memory module insertion and removal.

[0043] The process for automatic insertion and removal of the servo-driven DIMM module in this implementation is as follows:

[0044] The control board 2 and the sensing side plate 41 are connected to the control back end. Then, the servo drive component 3 is started through the back end. Its output end drives the downward moving rod 61 to move down through the nut block 34. During the first stage of the insertion process, the downward moving rod 61 drives the first downward moving frame 62 and the wedge-shaped protrusions on both sides to move down. The roller 72 contacts the surface of the wedge-shaped protrusion and drives the claw assembly 7 to open outward by a certain distance. The sliding groove 53 limits the movement of the claw assembly 7. During the movement, the pressing rod 64 contacts the middle pressing column 83. This is the position movement that occurs in the first stage of the insertion process and is determined as the first displacement distance. When the pressing rod 64 contacts the middle pressing column 83, the positive and negative poles set between them are connected. The first displacement distance is determined by the time period from the start time of the servo drive component 3 to the power-on state time point combined with the movement rate.

[0045] After completing the first stage of the insertion process, the servo drive component 3 remains in the start state, continuously driving the second lowering component 8 and the clamping component 9 to move down until the memory module is inserted into the insertion slot block 10, thus completing the second stage of the insertion process; conversely, the memory module removal process is completed.

[0046] During the second-stage insertion process, the vibration sensor 63 monitors the vibration data of this stage. When the memory module is not inserted into the insertion slot 10, the clamping component 9 has a certain floating range, so vibration data within the preset amplitude range will be established.

[0047] Record the number of times the vibration data measured by the vibration sensor 63 in this stage is not within the preset amplitude range, calculate the ratio of this number of acquisitions to the total number of acquisitions set in this stage, and record it as the actual over-amplitude frequency β. Establish a reasonable over-amplitude frequency β0. When β < β0, it indicates that the module floats normally during the second stage insertion process. When β ≥ β0, it indicates that the module floats abnormally during the second stage insertion process. Anomaly detection should be performed at the back end to find the cause.

[0048] Specifically, when performing anomaly detection, when retrieving the force data of two sensing elastic elements 55 in the same group, a time-force value curve is established based on the two sets of force data to obtain force curve L1 and force curve L2. At the same time, a reasonable force curve L0 is added. The reasonable force curve L0 is a reasonable change curve state diagram of the sensing elastic element 55 under the same parameter settings.

[0049] When a floating anomaly occurs, the force curve L1 and the force curve L2 are first fitted and compared. When the fitting degree between the force curve L1 and the force curve L2 is low, it indicates that the supporting force applied by the sensing elastic element 55 on both sides of the same group is unbalanced, which can easily lead to unstable insertion of memory modules. Therefore, the backend directly alarms and suspends the performance testing process of the module.

[0050] When the fitting degree between the force curves L1 and L2 is high, it indicates that there is a loosening problem between the module components. By comparing the fitting of the two sets of force curves with the reasonable force curve, the cause of loosening can be investigated. When the fitting degree is high, the connection between each component should be checked for stability. When the fitting degree is low, the sensing elastic element 55 should be replaced first. In addition, the detection results of the displacement detection component 4 can be used for verification. The above detection is repeated to investigate the specific cause. Fault self-check and alarm are completed under the design of the module itself to ensure the insertion stability and safety of the memory module during the insertion and removal process.

[0052] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention, and not to limit them. Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features, and these modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the spirit and scope of the technical solutions of the embodiments of the present invention.
