It should be understood that this disclosure can have various variations in different embodiments without departing from the scope of this disclosure, and the descriptions and drawings therein are illustrative in nature and not intended to limit this disclosure.

Nothing in this specification should be construed as requiring a specific three-dimensional orientation of the structure to fall within the scope of this disclosure.

[0044] See Figure 1 This illustration shows a perspective view of a motherboard testing apparatus 100 according to the present disclosure in an operational state. In this exemplary embodiment, the motherboard testing apparatus 100 is described using a motherboard 200 adapted to an M.2 solid-state drive as an example. It will be readily understood by those skilled in the art that various modifications, additions, substitutions, deletions, or other changes may be made to the following specific embodiments to apply the relevant designs of the present disclosure to the insertion and removal testing of other types of motherboards 200, and these changes remain within the scope of the principles of the motherboard testing apparatus 100 according to the present disclosure.

[0045] like Figure 1 As shown, in one embodiment of this disclosure, the motherboard testing apparatus 100 is used to automatically insert and remove test accessories 300 onto a motherboard 200 to be tested. The motherboard testing apparatus 100 includes a frame 110, an adapter mechanism 120, and a drive mechanism 130. (See also...) Figures 2 to 16 , Figure 2 and Figure 3The diagrams show two different perspectives of the motherboard testing device 100 in another working state. Figures 4 to 6 The diagrams show representative steps in the insertion process of the adapter card 123 and the first connector 210.

Figure 11 China representatively shows Figure 7 An enlarged schematic diagram of part A in the diagram; Figure 12 China representatively shows Figure 10 An enlarged schematic diagram of part B in the diagram; Figure 13 China representatively shows Figure 1 A magnified view of a portion of the image; Figure 14 and Figure 15 The diagrams show partial exploded views of the adjustment mechanism 140 from two different perspectives, respectively. Figure 16 China representatively shows Figure 15 An enlarged schematic diagram of part C in the figure. The structure, connection method, and functional relationship of each major component of the motherboard testing device 100 proposed in this disclosure will be described in detail below with reference to the above-mentioned figures.

[0046] like Figures 1 to 6As shown, in one embodiment of this disclosure, the frame 110 includes a base plate 111 for supporting the motherboard 200. The adapter mechanism 120 is disposed above the base plate 111 and includes a fixed block 121, a movable block 122, and an adapter tool holder 123. The movable block 122 is rotatably connected to the lower part of the fixed block 121 via a horizontally arranged pivot 124. One end of the adapter tool holder 123 is connected to the movable block 122, and the other end of the adapter tool holder 123 is provided with a first connecting portion 1231 (e.g., a gold finger), which is used to detachably fix the test accessory 300. A reset elastic element 125 is provided between the fixed block 121 and the movable block 122 to keep the adapter tool holder 123 in an inclined state under normal conditions. The drive mechanism 130 is used to drive the fixed block 121 to rise and fall. Accordingly, this disclosure utilizes the drive mechanism 130 to drive the fixing block 121 downwards, causing the other end of the tilted adapter card 123 to contact the first connector 210 of the motherboard 200. Continuing to drive the fixing block 121 downwards, the adapter card 123 rotates, causing the first connecting part 1231 to engage with the first connector 210. Through this structural design, this disclosure enables automatic insertion and removal of the adapter card 123 from the motherboard 200 under test, thereby achieving connection and disconnection between the test accessory 300 on the adapter card 123 and the motherboard 200. This reduces the user's workload, improves the testing efficiency of the motherboard 200, and avoids operational errors caused by manual operation, ensuring the accuracy of test results.

[0047] Specifically, the socket 211 of the first connector 210 of the motherboard 200 has a specific tilt angle, and it needs to be inserted at an angle during the insertion and removal process. The assembled test accessory 300 is roughly horizontal. In this regard, the present disclosure utilizes the design of the adapter card 123 to maintain a tilted state under normal conditions, so that the first connecting part 1231 can automatically adapt to the tilted structure of the socket 211 of the first connector 210 during the insertion of the first connecting part 1231 into the first connector 210.

[0048] As described above, the steps for inserting the adapter card 123 into the first connector 210 of the motherboard 200 include: (See below) Figure 4 The adapter card 123 is normally tilted at a certain angle (e.g., α as described below). Driven by the drive mechanism 130, the adapter card 123 descends vertically and slowly approaches the first connector 210; see reference Figure 5After descending to a certain distance, the first connecting part 1231 of the adapter card 123 rests on the interface at the socket 211 of the first connector 210. At this time, one end of the first connecting part 1231 of the adapter card 123 is blocked from further descent. As the drive mechanism 130 continues to drive the descent (for example, driving the fixed block 121 to descend), the adapter card 123 and the movable block 122 rotate upward relative to the fixed block 121 about the pivot 124, and the first connecting part 1231 translates along the interface and enters the socket 211; see reference Figure 6 After descending to the designated position (for example, when the bottom end of the limiting part 1133 contacts the base plate 111), the adapter card 123 completes the insertion of the first connecting part 1231 into the socket 211 of the first connector 210 and stops rotating, thus completing one insertion process.

[0049] like Figure 4 As shown, in one embodiment of this disclosure, the reset elastic element 125 can be a torsion spring, which is sleeved on the rotating shaft 124, with its two ends abutting against the fixed block 121 and the movable block 122, respectively. In other embodiments of this disclosure, the reset elastic element 125 can also adopt other elastic structures, such as a spring sheet or a leaf spring, and is not limited to this embodiment.

[0050] like Figure 4 As shown, in one embodiment of this disclosure, the adapter mechanism 120 may further include an adjusting bolt 126. The adjusting bolt 126 passes through a threaded hole in the fixed block 121, and is spaced apart from the rotating shaft 124. The lower end of the adjusting bolt 126 extends out of the fixed block 121 and abuts against the top of the movable block 122. Accordingly, the tilt angle of the adapter tool holder 123 in its normal state can be adjusted by adjusting the adjusting bolt 126. For example, taking the adjusting bolt 126 as being located on the side of the rotating shaft 124 away from the first connecting portion 1231, when it is necessary to reduce the tilt angle of the adapter tool holder 123 in its normal state, the adjusting bolt 126 can be rotated to move it further toward the movable block 122. During this process, the movable block 122 further presses against the reset elastic member 125. When it is necessary to increase the tilt angle of the adapter tool card 123 under normal conditions, the adjusting bolt 126 can be rotated in the opposite direction to move it away from the movable block 122, and the reset elastic element 125 will be released, thereby causing the reset elastic element 125 to push against the movable block 122 and drive the adapter tool card 123 to rotate.

[0051] It should be noted that the so-called "normal state" can be understood as the state when the adapter card 123, which holds the test accessory 300, is not in contact with the first connector 210. In other words, at this time, the tilt angle of the adapter card 123 is only affected by the action of the reset elastic element 125 and the gravity of the adapter card 123 and the test accessory 300. Based on this, as Figure 5As shown, the angle between the adapter card 123, which is in a tilted state under normal conditions, and the horizontal plane is α. α can be derived using the formula cosα = L2 / L1, where L1 is the length of the adapter card 123 from the pivot 124 to the first connecting part 1231 in its extension direction, and L2 is the horizontal distance between the pivot 124 and the entrance of the socket 211, which is also the horizontal distance between the pivot 124 and the end of the adapter card 123 (i.e., the first connecting part 1231). Since L2 = L1 - L3, α can be derived using the formula cosα = (L1 - L3) / L1, where L3 is the distance the first connecting part 1231 slides within the socket 211 of the first connector 210.

[0052] like Figures 7 to 12 As shown, in one embodiment of this disclosure, the adapter card 123 may be provided with a second connector 1232 and a damping knob 1233 arranged at intervals. The second connector 1232 is electrically connected to the first connecting portion 1231 of the adapter card 123, and the second connector 1232 is used for the second connecting portion (e.g., gold fingers) of the test accessory 300 to be inserted. The damping knob 1233 is adjustablely connected to the adapter card 123 and is used to lock or release the test accessory 300 so that it can be inserted and removed by the second connector 1232. In addition, a spring terminal may be provided in the socket of the second connector 1232. The push-pull action is at a certain angle to the horizontal plane. For example, the test accessory 300 of the M.2 solid-state drive can be inserted in an inclined direction and slide a certain distance, and then pressed down by the joint to a horizontal state, thereby making better contact between the second connecting portion of the M.2 solid-state drive and the second connector 1232 of the adapter card 123. Through the above structural design, this disclosure can realize the electrical connection between the test accessory 300 and the first connecting part 1231, and at the same time realize the locking or unlocking of the test accessory 300 on the adapter card 123, ensuring the stability of the test accessory 300 during the insertion and removal process between the adapter card 123 and the motherboard 200.

[0053] As above, taking an M.2 SSD as an example, the steps for fixing an M.2 SSD to the adapter card 123 include: (See attached instructions) Figure 7 First, turn on the damping knobs 1, 2, 3, and 3; see below. Figure 8 and Figure 11 Insert the second connector of the M.2 SSD into the second connector 1232 of the adapter card 123. At this time, the spring terminals inside the second connector 1232 activate, and the M.2 SSD is in a tilted-up position. (See attached image) Figure 9 Press the M.2 SSD flat; see below. Figure 10 and Figure 12 Turn off damping knob 1233 and use it to lock the M.2 SSD. The disassembly process of the M.2 SSD can be deduced by reversing the above steps, and will not be repeated here.

[0054] like Figures 1 to 3 As shown, in one embodiment of this disclosure, the frame 110 may further include a guide post 112 and a lifting plate 113. The guide post 112 is disposed on the base plate 111. The lifting plate 113 is disposed above the base plate 111 and slidably sleeved on the guide post 112. Based on this, a fixing block 121 can be connected to the lifting plate 113, and a drive mechanism 130 is used to drive the lifting plate 113 to rise and fall. Accordingly, when the drive mechanism 130 drives the lifting plate 113 to rise and fall, it can also drive the adapter tool card 123 to rise and fall.

[0055] like Figures 1 to 3 As shown, based on the structural design of the rack 110 including the lifting plate 113, in one embodiment of this disclosure, the lifting plate 113 may be provided with an adjustment mechanism 140, and the fixing block 121 is connected to the adjustment mechanism 140. The adjustment mechanism 140 is used to adjust the relative position of the fixing block 121 and the lifting plate 113. Through the above structural design, this disclosure can use the adjustment mechanism 140 to realize the position adjustment of the adapter card 123, thereby making the insertion and removal during the testing process more accurate and adaptable to the insertion and removal requirements of different types of motherboards 200.

[0056] like Figures 13 to 15 As shown, based on the structural design of the frame 110 including the adjustment mechanism 140, in one embodiment of this disclosure, the adjustment mechanism 140 may include a fixed base 141, a first slide block 142, a second slide block 143, and a third slide block 144. The fixed base 141 is disposed on the lifting plate 113 and has a first slide rail 1411 extending along a first horizontal direction (e.g., direction D1 shown in the figure). The first slide block 142 is slidably disposed on the first slide rail 1411 and has a second slide rail 1421 extending along a second horizontal direction perpendicular to the first horizontal direction (e.g., direction D2 shown in the figure). The second slide block 143 is slidably disposed on the second slide rail 1421 and has a third slide rail extending in a vertical direction. The third slide block 144 is slidably disposed on the third slide rail and is connected to a fixing block 121, for example, the third slide block 144 is connected to the fixing block 121 via a connecting arm 145. Through the above structural design, this disclosure enables the time limit adjustment mechanism 140 to adjust the three-way position of the adapter card 123, namely, the XYZ-axis adjustment.

[0057] For example, the adjusting mechanism 140 can specifically adopt a "lead screw" translational adjusting structure. Specifically, the following explanation uses the adjusting structure in the first horizontal direction of the adjusting mechanism 140 as an example, specifically the sliding fit structure between the fixed seat 141 and the first sliding block 142: Figure 14 and Figure 15As shown, a first slide rail 1411 is provided on the base, and the first slide rail 1411 is provided with a slide groove 1412, with the groove opening facing the first slide block 142. A lead screw 1413 is provided on the fixed base 141, extending along a first horizontal direction and passing through the first slide rail 1411, with a portion of the lead screw 1413 located in the slide groove 1412. A slide groove 1426 is provided on the side of the first slide block 1422 facing the base, and a slider 1422 is provided at the bottom of the slide groove 1426, with a threaded hole 1423 passing through along the first horizontal direction. The first slide rail 1411 and the slide groove 1426 are slidably engaged, with the slider 1422 located in the slide groove 1412 and the lead screw 1413 passing through the threaded hole 1423. Based on this, one end of the lead screw 1413 can extend out of the fixed base 141 and be equipped with corresponding operating components (such as handwheels, knobs, etc.) for convenient turning by the user. When the lead screw 1413 rotates in the forward or reverse direction, the slider 1422 is constrained by the first slide block 142 and the groove wall of the slide groove 1412 and cannot rotate. The slider 1422 (i.e., the first slide block 142) is translated along the first horizontal direction through the cooperation of the lead screw 1413 and the thread hole 1423. In addition, the sliding cooperation structure between the first slide block 142 and the second slide block 143 along the second horizontal direction and the sliding cooperation structure between the second slide block 143 and the third slide block 144 along the vertical direction can adopt similar structures as described above, which will not be described in detail here. In other embodiments of this disclosure, other translation adjustment structure designs can also be adopted to achieve translation adjustment of the adjustment mechanism 140 in any direction, and are not limited to this embodiment.

[0058] like Figure 16 As shown, in one embodiment of this disclosure, a locking groove 1424 may be provided on the side surface of the first slide block 142 facing the fixed base 141. The locking groove 1424 extends along a first horizontal direction and is spaced apart from the slide groove 1426. Based on this, the first slide block 142 is provided with a locking bolt 1425, which is arranged perpendicular to the first horizontal direction (e.g., a second horizontal direction), and one end of the stud of the locking bolt 1425 extends into the locking groove 1424. Therefore, when adjustment in the first horizontal direction is required, the locking bolt 1425 can be loosened. After adjustment to the appropriate position, the locking bolt 1425 can be tightened so that one end of the stud presses against the side wall of the locking groove 1424 near the slide groove 1426. This causes a slight deformation or displacement of the corresponding part of the slide groove 1426 towards the first slide rail 1411, thereby increasing the friction between that side wall of the slide groove 1426 and the side wall of the first slide rail 1411, achieving locking in the first horizontal direction. Furthermore, the locking structure between the first slide block 142 and the second slide block 143 in the second horizontal direction, and the locking structure between the second slide block 143 and the third slide block 144 in the vertical direction, can each adopt similar structures as described above, and will not be elaborated upon here.

[0059] like Figure 3 As shown, based on the structural design of the frame 110 including the lifting plate 113, in one embodiment of this disclosure, the adjusting mechanism 140 can be disposed on the top surface of the lifting plate 113, and the connecting mechanism 120 can be located below the lifting plate 113. Furthermore, the lifting plate 113 can be provided with an opening 1131, and the third sliding seat can be connected to the fixing block 121 via a connecting arm 145 passing through the opening 1131. Through the above structural design, this disclosure arranges the adjusting mechanism 140 and the connecting mechanism 120 above and below the lifting plate 113 respectively, thereby facilitating the arrangement of the two mechanisms and improving the structural rationality of the device.

[0060] like Figures 1 to 3 As shown, based on the structural design of the frame 110 including a lifting plate 113 and guide columns 112, in one embodiment of this disclosure, the lifting plate 113 can be rectangular. Furthermore, there can be at least four guide columns 112, each passing through one of the four corners of the lifting plate 113. Through this structural design, this disclosure optimizes the guiding effect of the guide columns 112 on the lifting motion of the lifting plate 113, thereby improving the stability of the device.

[0061] like Figures 1 to 3 As shown, based on the structural design of the frame 110 including the lifting plate 113 and the guide column 112, in one embodiment of this disclosure, the lifting plate 113 can be sleeved on the guide column 112 via the linear bearing 1132.

[0062] like Figures 1 to 3 As shown, based on the structural design of the frame 110 including the lifting plate 113, in one embodiment of this disclosure, the bottom surface of the lifting plate 113 may be provided with a plurality of limiting portions 1133. These limiting portions 1133 are arranged at intervals along the periphery of the bottom surface of the lifting plate 113, and the height of the plurality of limiting portions 1133 is equal. Accordingly, the limiting portions 1133 can realize the lower limit of the lifting plate 113's lifting and lowering, avoiding excessive descent of the lifting plate 113 and damage to the main board 200.

[0063] like Figures 1 to 3As shown, based on the structural design of the frame 110 including the lifting plate 113 and the guide column 112, in one embodiment of this disclosure, the frame 110 may further include a top plate 114, which is disposed above the lifting plate 113 and connected to the top of the guide column 112. Furthermore, the drive mechanism 130 can be a telescopic cylinder, the telescopic rod 132 including a cylinder body 131 and a telescopic rod 132. The cylinder body 131 is disposed on the top plate 114, one end of the telescopic cylinder is connected to the cylinder body 131, and the other end passes through the top plate 114 and is connected to the lifting plate 113 via a floating joint 133. Through the above structural design, this disclosure utilizes the top plate 114 to arrange the drive mechanism 130, which is beneficial to improving the structural rationality. Simultaneously, this disclosure utilizes the floating joint 133 to connect the lifting plate 113 and the telescopic rod 132, enabling the lifting plate 113 (i.e., the adapter tool card 123) to have a certain degree of floating freedom relative to the telescopic rod 132 during the lifting process, improving the adaptability during the automatic insertion and removal process of the lifting drive.

[0064] Based on the structural design of the drive mechanism 130 as a telescopic cylinder, in one embodiment of this disclosure, the telescopic cylinder may be provided with a detection element such as a magnetic switch. Accordingly, when it descends to the lower limit position, for example when the bottom end of the limit part 1133 contacts the base plate 111, the magnetic switch receives a signal and notifies the test system that subsequent tests can be performed.

[0065] In one embodiment of this disclosure, the motherboard testing apparatus 100 may include at least two adapter mechanisms 120. For example, five adapter mechanisms 120 may be simultaneously provided on the lifting plate 113. Accordingly, when the drive mechanism 130 drives the lifting plate 113 to descend, it can simultaneously drive the five adapter mechanisms 120 to descend synchronously, thereby realizing the synchronous automatic insertion and removal testing of multiple test accessories 300 at five interface positions (e.g., the first connector 210) of the motherboard 200. Of course, the five interface positions for synchronous insertion and removal may all belong to the same motherboard 200, or they may belong to at least two different motherboards 200. This allows for the synchronous automatic insertion and removal testing of multiple interface positions of a single motherboard 200, or the synchronous automatic insertion and removal testing of multiple motherboards 200. Through the above structural design, this disclosure can achieve batch testing and further improve testing efficiency.

[0066] It should be noted that the motherboard test apparatus 100 shown in the accompanying drawings and described in this specification is merely a few examples of many test apparatuses capable of employing the principles of this disclosure. It should be clearly understood that the principles of this disclosure are by no means limited to any detail or component of the motherboard test apparatus 100 shown in the accompanying drawings or described in this specification.

[0067] In summary, the motherboard testing device 100 proposed in this disclosure includes a frame 110, a transfer mechanism 120, and a drive mechanism 130. The frame 110 supports the base plate 111 of the motherboard 200 via a base plate 111. The transfer mechanism 120 includes a fixed block 121, a movable block 122, and a transfer tool holder 123. The movable block 122 is rotatably connected to the lower part of the fixed block 121 via a horizontally arranged pivot 124. One end of the transfer tool holder 123 is connected to the movable block 122, and the other end is provided with a first connecting part 1231. The transfer tool holder 123 is used to detachably fix the test accessory 300. A reset elastic element 125 is provided between the fixed block 121 and the movable block 122 so that the transfer tool holder 123 remains in an inclined state under normal conditions. The drive mechanism 130 is used to drive the fixed block 121 to rise and fall. Accordingly, this disclosure can drive the fixing block 121 to descend, causing the other end of the tilted adapter card 123 to contact the first connector 210 of the motherboard 200. Continuing to drive the fixing block 121 to descend, the adapter card 123 rotates, causing the first connecting part 1231 to engage with the first connector 210. Through this structural design, this disclosure enables automatic insertion and removal of the adapter card 123 and the motherboard 200 under test, thereby achieving connection and disconnection between the test accessory 300 on the adapter card 123 and the motherboard 200. This reduces the user's workload, improves the testing efficiency of the motherboard 200, and avoids operational errors caused by manual operation, ensuring the accuracy of test results.
