Description

Technical Field

[0001] The present invention relates to the technical field of memory bar plug-in and pull-out testing, and in particular to a server mainboard memory bar plug-in and pull-out testing system. Background Art

[0002] The memory stick is one of the important components in the computer, responsible for storing the operating system and application runtime data. It is a place where the computer temporarily stores data, and the data will be lost when the computer is shut down or restarted. Its main function is to provide fast read and write storage space for the CPU. The memory stick can significantly affect the performance and response speed of the computer. The memory stick is usually installed in the memory slot of the motherboard. The memory slot can be divided into two types according to the different clamping methods, one is a single-sided clamp and the other is a double-sided clamp. The double-sided clamp is easy to realize automatic plugging and unplugging, but the plug-in and unplugging test of the memory slot with a single-sided clamp is difficult to perform. The memory stick plug-in and unplugging test system in the prior art is mainly used for the memory slot with a double-sided clamp. At the same time, only after one server motherboard is tested and removed, can the next server motherboard be clamped and then tested, and the test efficiency is low. Summary of the invention

[0003] In view of the above technical problems, the technical solution adopted by the present invention is: a server motherboard memory bar plug-in test system, comprising a main device, the main device comprising a bottom plate, a stand fixedly mounted on the bottom plate, the main device being used to place a server motherboard to be plugged and tested, a plug-in device and two lifting devices being arranged on the main device, the plug-in device comprising a connecting frame, the connecting frame being fixedly mounted on the stand, the plug-in device being used to perform a plug-in test on the server motherboard, the lifting device comprising a base, the base being fixedly mounted on the bottom plate, a server motherboard being placed on the main device, the server motherboard comprising a motherboard;

[0004] The plug-in and pull-out device comprises a plug-in motor fixedly mounted on the connecting frame, an alarm is provided on the plug-in motor, a plug-in gear is fixedly mounted on the motor shaft of the plug-in motor, a plug-in rack is slidably mounted in the connecting frame, the plug-in rack is meshed with the plug-in gear, a plug-in seat is fixedly mounted on the plug-in seat, a rotating pull-out frame is rotatably mounted on the plug-in seat, a connecting side plate is rotatably mounted on the rotating pull-out frame, a lower plate is fixedly mounted on the connecting side plate, a top plate is fixedly mounted on the rotating pull-out frame, a memory bar is fixedly mounted on the connecting side plate, a slide groove is provided on the rotating pull-out frame, a triangular plate is rotatably mounted on the connecting side plate, a cross-sliding column is fixedly mounted on the triangular plate, the cross-sliding column slides in the slide groove, an inner connecting rod is rotatably mounted on the cross-sliding column, a cylinder is rotatably mounted on the triangular plate, a rotating head is fixedly mounted on the top of the cylinder, an opening plate is rotatably mounted on the rotating head, the opening plate and the inner connecting rod are rotatably mounted, a limiting column is fixedly mounted on the connecting side plate, a limiting groove is arranged on the opening plate, and the limiting column slides in the limiting groove.

[0005] Furthermore, a limit plate is fixedly installed below the plug-in seat, so that the rotating pull-out frame can only rotate in one direction around the plug-in seat.

[0006] When the server motherboard is located under the memory stick, the rotation of the plug-in motor drives the plug-in gear to rotate, thereby driving the plug-in rack and the plug-in seat to descend along the connecting frame. When the memory stick enters the memory slot, the memory stick will contact the inclined surface of the single-side card block, causing the single-side card block to rotate outward relative to the memory slot. At the same time, the memory stick will compress the card strip spring piece, and finally the memory stick will reach under the single-side card block and the card strip spring piece. The single-side card block and the card strip spring piece will jam the memory stick. At this time, the single-side card block needs to be rotated outward to pull out the memory stick. The weight of the cylinder side on the rotating pull-out frame is greater than the weight on the other side, and the limit plate prevents the rotating pull-out frame from being flipped counterclockwise.

[0007] When the cylinder is not in operation, it can be compressed to a certain extent. When the memory stick needs to be pulled out, the plug-in motor reverses to drive the plug-in gear to rotate, thereby driving the plug-in rack and the plug-in seat to rise. At this time, the memory stick is stuck by the single-side block and the card strip shrapnel and cannot rise. When the plug-in seat rises, it first drives the rotating puller to rise. The rotating puller rotates relative to the connecting side plate. At this time, the top plate is separated from the lower plate, and the cross slide column slides in the slide groove, driving the triangular plate to rotate. At the same time, the opening plate is driven by the inner connecting rod to slide along the limit column through the limit groove, and the limit column drives the opening plate through the limit groove. When the memory stick is pulled out of the memory slot, the cylinder actively extends to reset the opening plate, and at the same time, the rotating pull-out frame rotates relative to the connecting side plate, so that the top plate contacts the lower plate again, so that the rotating pull-out frame and the lower plate return to a parallel state.

[0008] The torque of the plug-in motor is constant. When the memory stick cannot be pulled out or inserted, the plug-in motor will stop working and sound an alarm through the alarm set thereon.

[0009] Furthermore, the main device includes an outer plate and an inner plate fixedly mounted on the base plate, an outer slide rail fixedly mounted on the outer plate, an inner slide rail fixedly mounted on the inner plate, a screw motor fixedly mounted on the base plate, a screw rotatably mounted on the base plate, and the screw and the motor shaft of the screw motor fixedly mounted.

[0010] Furthermore, a lifting plate mechanism is provided on the inner slide rail, and the lifting plate mechanism includes an inner slide block slidably mounted on the inner slide rail, a fixed plate is fixedly mounted on the inner slide block, an outer slide sleeve is fixedly mounted on the fixed plate, an inner threaded frame is fixedly mounted on the outer slide sleeve, a lower connecting block is fixedly mounted on the inner threaded frame, the inner threaded frame and the lead screw form a threaded transmission, a lifting column is slidably mounted in the outer sleeve, a lifting plate is fixedly mounted on the lifting column, an outer limit strip and a top limit strip are fixedly mounted on the lifting plate, a side sliding column is slidably mounted on the lifting plate, a movable clamping block is fixedly mounted on the side sliding column, a side spring is provided between the movable clamping block and the lifting plate, a rotating roller is rotatably mounted on the movable clamping block, and a pushing block is fixedly mounted below the lifting plate.

[0011] Furthermore, a translation plate mechanism is arranged on the outer slide rail, and the translation plate mechanism includes an outer slide block slidably mounted on the outer slide rail, a translation placement plate is fixedly mounted on the outer slide block, an outer limit bar and a front limit bar are fixedly mounted on the translation placement plate, a limit slide column is slidably mounted on the translation placement plate, a movable limit bar is fixedly mounted on the limit slide column, a slide column spring is arranged between the movable limit bar and the translation placement plate, an opening roller is rotatably mounted on the movable limit bar, and an upper connecting block is fixedly mounted below the translation placement plate.

[0012] Furthermore, a synchronization mechanism is arranged on the outer plate, and the synchronization mechanism comprises four transmission wheels rotatably mounted on the outer plate, a transmission belt is wound around the transmission wheels, a lower connecting block is fixedly mounted on the transmission belt, and an upper connecting block is fixedly mounted on the transmission belt.

[0013] Furthermore, an opening shell is fixedly mounted on the outer plate, and an inclined bar is arranged inside the opening shell. When the rotating roller or the opening roller reaches the opening shell, the rotating roller or the opening roller rolls along the inclined bar.

[0014] The rotation of the screw motor drives the screw to rotate, thereby driving the internal thread frame, the outer sleeve, the fixed plate and the inner slider to slide along the inner slide rail, thereby driving the lifting plate to move. At the same time, the lower connecting block drives the transmission belt to move, and the transmission belt drives the outer slider, the upper connecting block and the translation plate to slide along the outer slide rail. The moving directions of the lifting plate and the translation plate are always opposite.

[0015] When the server motherboard on the lifting and placing plate is tested, the next server motherboard to be tested is placed on the translation placing plate, and the motherboard is inserted into the outer limit bar and the front limit bar. At this time, the opening roller is stretched open by the oblique bar, and the slide column spring is in a compressed state. When the translation placing plate leaves the opening shell, the opening roller slides out along the oblique bar, and the slide column spring is reset, so that the movable limit bar and the limit slide column slide along the translation placing plate, and the motherboard is clamped by the movable limit bar, the outer limit bar and the front limit bar. Similarly, the motherboard on the lifting and placing plate is clamped by the outer limit bar, the top limit bar and the movable clamping block, and the clamping is released when the lifting and placing plate reaches the opening shell.

[0016] Furthermore, the lifting device includes a front rotating rod and a rear rotating rod rotatably mounted on the base, a lifting top seat is rotatably mounted on the front rotating rod, the lifting top seat is rotatably mounted on the rear rotating rod, a slide rod is rotatably mounted on the base, a limited slide groove is arranged on the slide rod, an inner rod is rotatably mounted on the lifting top seat, a sliding column is fixedly mounted on the inner rod, and the sliding column slides in the limited slide groove.

[0017] Under normal circumstances, due to the heavy weight of the lifting top seat, the lifting top seat presses down the rear rotating rod and the front rotating rod, and the sliding column can slide in the limiting slide groove, and the lowest point position of the lifting top seat is limited by the limiting slide groove. When the lifting plate moves with the pushing block, when the pushing block contacts the lifting top seat, it will push the lifting top seat, and the lifting top seat rises while rotating relative to the base through the front rotating rod and the rear rotating rod. The lifting top seat drives the lifting plate and the lifting column to rise along the outer sliding sleeve. Similarly, when the pushing block leaves the lifting top seat, the lifting top seat falls and resets under the action of its own gravity. After the lifting top seat leaves the bottom of the lifting plate, the lifting plate descends along the outer sliding sleeve through the lifting column under the action of gravity.

[0018] When the lifting and placing plate with the inspected server motherboard moves toward the open shell and leaves the top of the lifting top seat, the lifting and placing plate descends. At this time, the translation placing plate with the server motherboard to be inspected passes over the lifting and placing plate and arrives under the vertical frame. When the lifting and placing plate arrives at the lifting top seat next to the open shell, the lifting and placing plate is raised by the lifting top seat to remove the inspected server motherboard. After the server motherboard on the translation placing plate is inspected, the lifting and placing plate is made to reach under the vertical frame again in the same way, and the translation placing plate arrives next to the open shell.

[0019] Furthermore, the server mainboard comprises a mainboard, a memory slot is fixedly mounted on the mainboard, a plurality of single-sided card blocks are rotatably mounted on the memory slot, and a plurality of card strip springs are arranged on the memory slot.

[0020] Compared with the prior art, the present invention has the following beneficial effects: (1) The plug-in and pull-out device provided in the present invention can automatically perform multiple plug-in and pull-out tests on the memory slot on the server motherboard. At the same time, during the rising process, the locking of the memory stick by the single-side card block is first released by opening the plate, and then one end of the memory stick is first pulled out. After being pulled out to a certain angle, the other end of the memory stick is separated from the card strip spring to realize the pulling out of the memory stick. The plug-in and pull-out effect is good, and the plug-in and pull-out test of the memory slot with a single-side card clamp can be realized; (2) The main device provided in the present invention can realize the position switching of the lifting placement plate and the translation placement plate, and the two placement plates move synchronously. When the lifting placement plate and the server motherboard thereon are under the stand for plug-in and pull-out test, the translation placement plate is located at the open shell, and the next server motherboard to be tested is placed, which saves the test time and improves the test efficiency; (3) The two lifting devices provided in the present invention enable the lifting placement plate to automatically rise when it is under the stand and at the open shell, and when the lifting placement plate is in other positions, it is located under the translation placement plate, so that the two placement plates can interchange positions without interference.

DETAILED DESCRIPTION

[0035] The specific implementation of the present invention will be further described below in conjunction with the accompanying drawings.

[0037] like Figure 2-Figure 4 As shown, the plug-in device includes a plug-in motor 202 fixedly mounted on a connecting frame 201, an alarm is arranged on the plug-in motor 202, a plug-in gear 203 is fixedly mounted on the motor shaft of the plug-in motor 202, a plug-in rack 204 is slidably mounted in the connecting frame 201, the plug-in rack 204 is meshed with the plug-in gear 203, a plug-in seat 205 is fixedly mounted on the plug-in rack 204, a rotating pull-out frame 206 is rotatably mounted on the plug-in seat 205, a connecting side plate 209 is rotatably mounted on the rotating pull-out frame 206, a lower plate 207 is fixedly mounted on the connecting side plate 209, a top plate 219 is fixedly mounted on the rotating pull-out frame 206, and a memory module 219 is fixedly mounted on the connecting side plate 209. 208, a slide groove 210 is provided on the rotating pull-out frame 206, a triangular plate 211 is rotatably installed on the connecting side plate 209, a horizontal sliding column 213 is fixedly installed on the triangular plate 211, the horizontal sliding column 213 slides in the slide groove 210, an inner connecting rod 212 is rotatably installed on the horizontal sliding column 213, a cylinder 214 is rotatably installed on the triangular plate 211, a rotating head 215 is fixedly installed on the top of the cylinder 214, an opening plate 216 is rotatably installed on the rotating head 215, the opening plate 216 is rotatably installed with the inner connecting rod 212, a limiting column 217 is fixedly installed on the connecting side plate 209, a limiting groove 218 is provided on the opening plate 216, and the limiting column 217 slides in the limiting groove 218.

[0038] like Figure 2-Figure 4 As shown, a limit plate 220 is fixedly installed below the plug socket 205 so that the rotating pull frame 206 can only rotate in one direction around the plug socket 205 .

[0039] When the server motherboard is located below the memory stick 208, the plug-in motor 202 rotates to drive the plug-in gear 203 to rotate, thereby driving the plug-in rack 204 and the plug-in seat 205 to descend along the connecting frame 201. When the memory stick 208 enters the memory slot 402, the memory stick 208 will contact the inclined surface of the single-side clamping block 403, so that the single-side clamping block 403 rotates outward relative to the memory slot 402. At the same time, the memory stick 208 will compress the clamping strip spring piece 404. Finally, the memory stick 208 arrives below the single-side clamping block 403 and the clamping strip spring piece 404. The single-side clamping block 403 and the clamping strip spring piece 404 will clamp the memory stick 208. At this time, the single-side clamping block 403 needs to be rotated outward to pull out the memory stick 208. The weight of the cylinder 214 side on the rotating pull-out frame 206 is greater than the weight of the other side. The limit plate 220 prevents the rotating pull-out frame 206 from being flipped counterclockwise.

[0040] The cylinder 214 can be compressed to a certain extent when it is not in operation. When the memory stick 208 needs to be pulled out, the plug-in motor 202 is reversed to drive the plug-in gear 203 to rotate, thereby driving the plug-in rack 204 and the plug-in seat 205 to rise. At this time, since the memory stick 208 is stuck by the single-side block 403 and the card strip spring 404 and cannot rise, when the plug-in seat 205 rises, it first drives the rotating pull-out frame 206 to rise, and the rotating pull-out frame 206 rotates relative to the connecting side plate 209. At this time, the top plate 219 is separated from the lower plate 207, and the horizontal sliding column 213 slides in the sliding groove 210, driving the triangular plate 211 to rotate, and at the same time, the opening plate 216 is driven by the inner connecting rod 212 to slide along the limiting column 217 through the limiting groove 218, and the limiting column 217 engages the opening plate 216 through the limiting groove 218. The limit is performed, and the outward movement of the opening plate 216 will drive the single-sided block 403 to rotate relative to the memory slot 402, so that the single-sided block 403 no longer blocks the memory stick 208. During the outward movement of the opening plate 216, the cylinder 214 is compressed, and then the plug-in seat 205 continues to rise, so that the memory stick 208 is pulled out first near the single-sided block 403. At this time, the connecting side plate 209 and the memory stick 208 are in an inclined state, and then the memory stick 208 is pulled out from the card strip shrapnel 404. When the memory stick 208 leaves the memory slot 402, the cylinder 214 actively extends to reset the opening plate 216. At the same time, the rotating pull-out frame 206 rotates relative to the connecting side plate 209, so that the top plate 219 contacts the lower plate 207 again, so that the rotating pull-out frame 206 and the lower plate 207 return to a parallel state.

[0041] The torque of the plug-in motor 202 is constant. When the memory stick 208 cannot be pulled out or inserted, the plug-in motor 202 stops working and an alarm is sounded through the alarm arranged thereon.

[0046] like Figure 5-Figure 8As shown, an opening shell 109 is fixedly mounted on the outer plate 103 , and an inclined bar 110 is arranged inside the opening shell 109 . When the rotating roller 117 or the opening roller 135 reaches the opening shell 109 , the rotating roller 117 or the opening roller 135 rolls along the inclined bar 110 .

[0047] The rotation of the screw motor 104 drives the screw 108 to rotate, thereby driving the internal thread frame 122, the outer sleeve 124, the fixed plate 125 and the inner slider 126 to slide along the inner slide rail 106, thereby driving the lifting and placing plate 111 to move, and at the same time the lower connecting block 123 drives the transmission belt 120 to move, and the transmission belt 120 will drive the outer slider 118, the upper connecting block 119 and the translation placing plate 129 to slide along the outer slide rail 107, and the moving directions of the lifting and placing plate 111 and the translation placing plate 129 are always opposite.

[0048] When the server motherboard on the lifting and placing plate 111 is tested, the next server motherboard to be tested is placed on the translation placing plate 129, and the motherboard 401 is inserted into the outer limit bar 130 and the front limit bar 131. At this time, the opening roller 135 is stretched open by the inclined bar 110, and the slide spring 134 is in a compressed state. When the translation placing plate 129 leaves the opening shell 109, the opening roller 135 slides out along the inclined bar 110, and the slide spring 134 is reset, so that the movable limit bar 132 and the limit slide 133 slide along the translation placing plate 129, and the motherboard 401 is clamped by the movable limit bar 132, the outer limit bar 130 and the front limit bar 131. Similarly, the motherboard 401 on the lifting and placing plate 111 is clamped by the outer limit bar 112, the top limit bar 113 and the movable clamping block 114, and is released when the lifting and placing plate 111 reaches the opening shell 109.

[0050] Under normal conditions, due to the heavy weight of the lifting top seat 304, the lifting top seat 304 presses down the rear rotating rod 303 and the front rotating rod 302, and the sliding column 307 can slide in the limiting slide groove 308, and the lowest point position of the lifting top seat 304 is limited by the limiting slide groove 308. When the lifting placement plate 111 moves with the pushing block 128, when the pushing block 128 contacts the lifting top seat 304, it will push the lifting top seat 304, and the lifting top seat 304 is lifted by the front rotating rod 302 and The rear rotating rod 303 rises while rotating relative to the base 301, and the lifting top seat 304 drives the lifting plate 111 and the lifting column 127 to rise along the outer sliding sleeve 124. Similarly, when the pushing block 128 leaves the lifting top seat 304, the lifting top seat 304 falls and resets under the action of its own gravity. After the lifting top seat 304 leaves under the lifting plate 111, the lifting plate 111 descends along the outer sliding sleeve 124 through the lifting column 127 under the action of gravity.

[0051] When the lifting and placing plate 111 moves with the inspected server motherboard toward the open shell 109 and leaves the lifting top seat 304, the lifting and placing plate 111 descends. At this time, the translation placing plate 129 passes through the lifting and placing plate 111 with the server motherboard to be inspected and arrives under the stand 102. When the lifting and placing plate 111 arrives at the lifting top seat 304 next to the open shell 109, the lifting and placing plate 111 is lifted up by the lifting top seat 304 to remove the inspected server motherboard. After the server motherboard on the translation placing plate 129 is inspected, the lifting and placing plate 111 is made to reach the bottom of the stand 102 again in the same way, and the translation placing plate 129 arrives next to the open shell 109.

[0052] like Figure 11-13 As shown, the server motherboard includes a motherboard 401 , a memory slot 402 is fixedly mounted on the motherboard 401 , a plurality of single-sided card blocks 403 are rotatably mounted on the memory slot 402 , and a plurality of card strip springs 404 are arranged on the memory slot 402 .

[0053] The working principle of the server motherboard memory bar plug-in and pull-out test system disclosed in the present invention is as follows: when the lifting and placing plate 111 is located at the opening shell 109, the inclined bar 110 opens the movable clamping block 114 by rotating the roller 117, and the motherboard 401 is placed in the outer limit bar 112 and the top limit bar 113. When the lifting and placing plate 111 leaves the opening shell 109, the movable clamping block 114 clamps the motherboard 401 under the action of the side spring 116, and the screw motor 104 rotates. The screw rod 108 is driven to rotate, thereby driving the internal thread frame 122, the outer sliding sleeve 124, the fixed plate 125 and the inner slider 126 to slide along the inner slide rail 106, thereby driving the lifting and placing plate 111 to move. At the same time, the lower connecting block 123 drives the transmission belt 120 to move. The transmission belt 120 will drive the outer slider 118, the upper connecting block 119 and the translation placing plate 129 to slide along the outer slide rail 107. The movement direction of the lifting and placing plate 111 is opposite to that of the translation placing plate 129. When the lifting and placing plate 111 moves to the bottom of the connecting frame 201, the motherboard 401 is located below the memory bar 208. The plug-in motor 202 rotates to drive the plug-in gear 203 to rotate, thereby driving the plug-in rack 204 and the plug-in seat 205 to descend along the connecting frame 201. When the memory bar 208 enters the memory slot 402, the memory bar 208 will contact the inclined surface of the single-side card block 403, so that the single-side card block 403 rotates outward relative to the memory slot 402. When the memory stick 208 is pulled out, the weight of the cylinder 214 on the rotating pull-out frame 206 is greater than the weight of the other side, and the limit plate 220 prevents the rotating pull-out frame 206 from being flipped counterclockwise.When the cylinder 214 is not in operation, it can be compressed to a certain extent. When the memory stick 208 needs to be pulled out, the plug-in motor 202 is reversed to drive the plug-in gear 203 to rotate, thereby driving the plug-in rack 204 and the plug-in seat 205 to rise. At this time, since the memory stick 208 is stuck by the single-side block 403 and the card strip spring 404 and cannot rise, when the plug-in seat 205 rises, it first drives the rotating pull frame 206 to rise, and the rotating pull frame 206 rotates relative to the connecting side plate 209. At this time, the top plate 219 is separated from the lower plate 207, and the horizontal sliding column 213 slides in the sliding groove 210, driving the triangular plate 211 to rotate, and at the same time, the opening plate 216 is driven by the inner connecting rod 212 to pass through the limit groove 218 along the As the limiting column 217 slides, the limiting column 217 limits the opening plate 216 through the limiting groove 218. The outward movement of the opening plate 216 will drive the single-side block 403 to rotate relative to the memory slot 402, so that the single-side block 403 no longer blocks the memory stick 208. During the outward movement of the opening plate 216, the cylinder 214 is compressed, and then the plug-in seat 205 continues to rise, so that the memory stick 208 is pulled out first near the single-side block 403. At this time, the connecting side plate 209 and the memory stick 208 are in an inclined state, and then the memory stick 208 is pulled out from the card strip shrapnel 404. When the memory stick 208 leaves the memory slot 402, the cylinder 214 actively extends, so that the opening plate 216 is reset, and at the same time When the memory stick 208 is pulled out or inserted, the plugging motor 202 stops working and alarms through the alarm device arranged thereon. Under normal circumstances, due to the large weight of the lifting top seat 304, the lifting top seat 304 presses down the rear rotating rod 303 and the front rotating rod 302, and the sliding column 307 can slide in the limiting slide groove 308, and the lifting top seat 308 is limited by the limiting slide groove 308. 4, when the lifting plate 111 moves with the pushing block 128, when the pushing block 128 contacts the lifting top seat 304, it will push the lifting top seat 304, and the lifting top seat 304 will rise while rotating relative to the base 301 through the front rotating rod 302 and the rear rotating rod 303, and the lifting top seat 304 drives the lifting plate 111 and the lifting column 127 to rise along the outer sliding sleeve 124. Similarly, when the pushing block 128 leaves the lifting top seat 304, the lifting top seat 304 falls and resets under the action of its own gravity. After the lifting top seat 304 leaves the bottom of the lifting plate 111, the lifting plate 111 falls along the outer sliding sleeve 124 through the lifting column 127 under the action of gravity.When the lifting and placing plate 111 moves with the server motherboard that has been inspected toward the open shell 109 and leaves the lifting top seat 304, the lifting and placing plate 111 descends. At this time, the translation placing plate 129 passes through the lifting and placing plate 111 with the server motherboard to be inspected and arrives under the stand 102. When the lifting and placing plate 111 arrives at the lifting top seat 304 next to the open shell 109, the lifting and placing plate 111 is driven to rise by the lifting top seat 304. At this time, the movable clamp 114 opens, the server motherboard that has been inspected is removed, and the next server motherboard to be inspected is put in. After the server motherboard on the translation placing plate 129 is inspected, the lifting and placing plate 111 is made to reach the bottom of the stand 102 again in the same way, and the translation placing plate 129 arrives next to the open shell 109, the server motherboard that has been inspected on the translation placing plate 129 is removed, and the next server motherboard to be inspected is put in.
