Description

Technical Field

[0001] The invention relates to the technical field of computer accessory detection, in particular to factory detection equipment for slot-type memory and hard disk. Background Art

[0002] When slot-type memory sticks and slot-installed hard drives are manufactured and shipped out of the factory, sampling and testing are required. Usually, an external slot connected to the motherboard is used to directly insert the memory stick and hard drive for testing. The testing is performed by simulating normal startup through a virtual machine. However, scratches are easily left on the copper feet when plugging and unplugging, which damages the freshness of the copper feet.

[0003] The testing equipment currently used has the following disadvantages:

[0004] 1. The detection equipment currently used still needs to be plugged in and out, and lacks a connection structure that can avoid leaving scratches, which is not conducive to further triggering and connecting;

[0005] 2. The testing mechanism is exposed and lacks protective auxiliary structures;

[0006] 3. Lack of auxiliary deceleration mechanism to limit release protection. Summary of the invention

[0007] In view of this, the present invention provides a factory inspection device for slot-type memory and hard disk, which has a transparent steel glass shield, providing a protective auxiliary structure. When the transparent steel glass shield moves backward, it can drive the trigger block to move backward. When the transparent steel glass shield closes the connection assembly plate, the trigger block contacts the external power button to trigger the power on for inspection.

[0011] Optionally, four groups of guide rods B offset from the guide rods A are fixedly arranged on the inner wall below the two ends of the memory detector; two groups of connecting frames A are slidingly arranged outside the two groups of guide rods A, and springs are sleeved on the outer sides of the guide rods A between the two groups of connecting frames A; micro-contacts A are slidingly arranged on adjacent surfaces of the connecting frames A on both sides in cooperation with the springs, and circuits are arranged outside the micro-contacts A to connect the built-in mainboard of the detection chassis; a trigger is slidingly arranged outside the guide rods B, and a spring is sleeved on the lower outer side of the guide rods B.

[0012] Optionally, both ends of the connecting frame A are set as turning structures, and the top of the turning structure is set as a slope; the bottom inner corners of the trigger are set as slope structures, and the adjacent surfaces of the triggers on both sides are integrally provided with a downward-turning L-shaped structure, forcing the triggers on both sides to move closer when the trigger descends.

[0013] Optionally, a guide structure with three slopes is integrally provided on the inner side of the top of the insertion-assisting device; guide wheels arranged in bidirectional directions, horizontally and vertically, are rotatably provided on both sides and in the middle of the insertion-assisting device.

[0014] Optionally, the upper and lower ends of the trigger frame are integrally provided with outward-bending trapezoidal feet; guide rods C are fixedly provided at the upper and lower ends between the inner walls on both sides of the hard disk detector, two groups of connecting frames B are slidably provided outside the two groups of guide rods C, and springs are provided outside the guide rods C between the connecting frames B on both sides; micro contacts B are slidably provided on adjacent surfaces of the connecting frames B on both sides in cooperation with the springs, and circuits are provided outside the micro contacts B to connect the built-in mainboard of the detection chassis.

[0015] Optionally, trapezoidal protrusions are integrally provided on the outer sides of the upper and lower ends of the connecting frame B, and when the trapezoidal legs move backwards, they can contact the connecting frame B to force the connecting frames B on both sides to move closer.

[0016] Optionally, a self-locking pull rod is slidably arranged above the front end of the auxiliary guide seat, and a U-shaped block is fixedly arranged at the rear end of the self-locking pull rod; the outer sleeve of the self-locking pull rod is provided with a spring for pushing the U-shaped block backwards.

[0017] The beneficial effects are as follows:

[0018] 1. The present invention is provided with a micro contact A and a micro contact B, providing a connection structure that can avoid leaving scratches, and automatically locks the hard disk and the memory stick by using elastic force. It is flexible and convenient when installing and disassembling, and it saves effort. The micro contact A and the micro contact B are both made of soft metal with round heads, which can avoid wearing the copper feet. If a fault occurs, they can be maintained separately to ensure that the memory stick and the hard disk are not damaged after the inspection.

[0019] 2. A transparent steel glass shield is provided to provide a protective auxiliary structure. When the transparent steel glass shield moves backward, it can drive the trigger block to move backward. When the transparent steel glass shield is closed and connected to the assembly plate, the trigger block contacts the external power button to trigger the power on and perform the test. After the test is completed or when the hard disk and memory stick are to be removed, the transparent steel glass shield is pulled back forward, and the trigger block will contact the external power button again to trigger the shutdown, ensuring that the hard disk and memory stick cannot be removed during the test, providing an anti-accidental touch function.

[0020] 3. A damper is set to provide an auxiliary deceleration mechanism for limiting the release of protection. When the transparent steel glass shutter is closed, the piston rod will also be stretched. When the piston rod is extended, air is pumped through the damper, and the air directly opens the one-way plate to move backward for replenishment. The resistance in this process is extremely small. When the transparent steel glass shutter is opened, the one-way plate is hindered by the reverse thrust and closed by air pressure to form a one-way valve. The air can only be discharged outward through the speed limiting hole, thereby achieving a deceleration effect, extending the opening time of the transparent steel glass shutter, and ensuring that the shutdown is completed after the transparent steel glass shutter is opened.

[0032] In order to make the purpose, scheme and advantages of the technical solution of the present invention clearer, the technical solution of the embodiment of the present invention will be clearly and completely described below in conjunction with the drawings of specific embodiments of the present invention.

[0033] Embodiment 1:

[0034] Please refer to the attached figure in the instruction manual. Figures 1 to 9 As shown:

[0035] The present invention proposes a factory inspection device for slot-type memory and hard disk, comprising: an inspection chassis 1, two groups of top slide bars 101 are fixedly arranged on both sides of the top of the inspection chassis 1, and a transparent steel glass shielding plate 102 is slidably arranged between the top slide bars 101; a damper 3 is fixedly arranged at the left front corner of the top of the inspection chassis 1; a connecting assembly plate 4 is fixedly arranged in the middle of the top rear side of the inspection chassis 1, a memory detector 5 is fixedly arranged on the top left side of the connecting assembly plate 4, a hard disk detector 7 is fixedly arranged on the top right rear end of the connecting assembly plate 4, and a hard disk detector 7 is fixedly arranged on the top right rear end of the connecting assembly plate 4. An auxiliary guide seat 8 is fixedly set at the front end of the side, and the hard disk detector 7 is aligned with the auxiliary guide seat 8; the memory detector 5 is a U-shaped structure with three sides fixed and wrapped, and two groups of guide rods A501 are fixedly set at the inner walls at both ends of the memory detector 5; a cushion block 701 is fixedly set in the middle of the inner wall facing forward in the hard disk detector 7; four groups of spring rods 702 are fixedly set on the upper and lower sides of the inner wall facing forward in the hard disk detector 7, and a trigger frame 703 is slidably set outside the spring rod 702, the spring rod 702 passes through the trigger frame 703 and is sleeved with a spring, and a limit plate is fixedly set at the front end of the trigger frame 703.

[0036] Among them, an external power button 2 is fixedly set on the top of the detection chassis 1. The external power button 2 adopts a spring-loaded mechanical button, and the button is set in a semicircular shape; a trigger block 103 is fixedly set at the lower part of the inner part of the transparent steel glass shield 102, and the trigger block 103 can contact the external power button 2 when the transparent steel glass shield 102 moves.

[0037] Among them, the front end of the damper 3 is an open structure, and six groups of inner spacers 301 are integrally arranged on both sides of the inside of the damper 3; a one-way plate 302 is rotatably arranged in the interval of the inner spacers 301, and the front end of the one-way plate 302 fits the inner spacers 301; a speed limiting hole 303 is opened in the middle of the inner spacers 301, and the speed limiting hole 303 is vertically aligned with the center position of the one-way plate 302; the rear end of the damper 3 is fixedly connected to the piston rod 304, and the telescopic end of the piston rod 304 is fixedly connected to the left rear end of the transparent steel glass shielding plate 102.

[0038] Among them, four groups of guide rods B502 offset from the guide rod A501 are fixedly arranged on the inner wall below the two ends of the memory detector 5; two groups of connecting frames A503 are slidably arranged outside the two groups of guide rods A501, and the outer side of the guide rod A501 between the two groups of connecting frames A503 is sleeved with springs; micro contacts A504 are slidably arranged on adjacent surfaces of the connecting frames A503 on both sides in cooperation with the springs, and a circuit is arranged outside the micro contact A504 to connect the built-in mainboard of the detection chassis 1; a trigger 505 is slidably arranged outside the guide rod B502, and a spring is sleeved on the lower outer side of the guide rod B502.

[0039] Among them, both ends of the connecting frame A503 are set as turning structures, and the top of the turning structure is set as an inclined surface; the bottom inner corners of the trigger 505 are set as inclined surfaces, and the adjacent surfaces of the triggers 505 on both sides are integrally provided with an L-shaped structure that turns downward. When the trigger 505 descends, it forces the triggers 505 on both sides to move closer.

[0040] A guide structure with three slopes is integrally arranged on the inner side of the top of the insertion aid device 6 ; guide wheels 601 arranged in both horizontal and vertical directions are rotatably arranged on both sides and in the middle of the insertion aid device 6 .

[0041] Among them, the upper and lower ends of the trigger frame 703 are integrally provided with outward-bending trapezoidal legs 704; guide rods C705 are fixedly provided at the upper and lower ends between the inner walls on both sides of the hard disk detector 7, and two groups of connecting frames B706 are slidably provided outside the two groups of guide rods C705, and springs are provided on the outer sleeves of the guide rods C705 between the connecting frames B706 on both sides; micro contacts B707 are slidably provided on the adjacent surfaces of the connecting frames B706 on both sides in cooperation with the springs, and circuits are provided outside the micro contacts B707 to connect the built-in mainboard of the detection chassis 1.

[0042] Among them, trapezoidal protrusions are integrally provided on the outer sides of the upper and lower ends of the connecting frame B706. When the trapezoidal support legs 704 move backwards, they can contact the connecting frame B706 and force the connecting frames B706 on both sides to move closer.

[0043] Among them, a self-locking pull rod 801 is slidably arranged above the front end of the auxiliary guide seat 8, and a U-shaped block 802 is fixedly arranged at the rear end of the self-locking pull rod 801; the outer sleeve of the self-locking pull rod 801 is provided with a spring for pushing the U-shaped block 802 backwards, and the spring adopts a high-force spring to ensure that the elasticity is greater than the sum of the external springs of the spring rod 702, ensuring that the four groups of spring rods 702 can be compressed.

[0044] like Figure 1-8 As shown, when testing the memory stick, the memory stick is directly inserted from the top of the memory detector 5, and the guide wheel 601 in the insertion aid device 6 assists in guiding so that the memory stick moves downward smoothly;

[0045] Manually press down the memory stick. When the memory stick contacts the L-shaped structure outside the trigger 505, the trigger 505 is driven down as a whole, and then the trigger 505 is used to approach the connecting frame A503. At this time, the spring outside the guide rod B502 provides a certain reaction force. When the trigger 505 is lowered to completely wrap the connecting frame A503, the connecting frame A503 and the trigger 505 are no longer fitted with an inclined surface, but with a flat surface. Figure 8The trigger 505 is stuck with the weight of the memory stick, and the two sets of connection frames A503 are moved closer, pushing the micro contacts A504 to contact the copper pins of the memory stick. Each set of micro contacts A504 will adaptively connect to different copper pins and help stabilize the memory stick. On the contrary, after the memory stick is removed, the connection frame A503 and the trigger 505 will automatically reset through the spring.

[0046] The micro contact A504 uses soft metal with a round head to avoid wearing the copper feet and leaving marks.

[0047] Embodiment 2:

[0048] On the basis of Example 1, Figure 7 and Fig. 9 As shown, when testing the hard disk, first pull open the self-locking lever 801, then place the slot-type hard disk into the auxiliary guide seat 8, with the copper feet of the slot-type hard disk facing the hard disk detector 7, release the self-locking lever 801, and the spring outside the self-locking lever 801 pushes the hard disk into the hard disk detector 7;

[0049] The hard disk detector 7 contacts the trigger frame 703 and presses the trigger frame 703 backwards, and then uses the trapezoidal legs 704 to force the connection frames B706 on both sides to move closer, and uses the micro-contact B707 to adaptively contact the copper legs of the hard disk to achieve connection;

[0050] This method is mainly applicable to mobile hard disks of M2.0 and above models, and can be adaptively adjusted when detecting other hard disks.

[0051] Embodiment 3:

[0052] On the basis of Example 1, during detection, the transparent steel glass shield 102 is pushed backward, and the transparent steel glass shield 102 is used to drive the trigger block 103 to move backward. When the transparent steel glass shield 102 is closed and connected to the assembly plate 4, the trigger block 103 contacts the external power button 2 to trigger the power on, and then the detection is performed;

[0053] During the test, the hard disk and memory stick are protected by the transparent steel glass shield 102, and the hard disk and memory stick cannot be directly removed. When the test is completed or the hard disk and memory stick are to be removed, the transparent steel glass shield 102 must be pulled back, and the trigger block 103 will contact the external power button 2 again to trigger shutdown, ensuring that the hard disk and memory stick cannot be removed during the test process, achieving the effect of preventing accidental touch;

[0054] When the steel glass shutter 102 is closed, the piston rod 304 is also stretched. When the piston rod 304 is stretched, air is sucked through the damper 3, and the air directly opens the one-way plate 302 to move backward for replenishment. The resistance in this process is extremely small. On the contrary, when the steel glass shutter 102 is opened, the one-way plate 302 is hindered by the reverse thrust and is closed by the air pressure to form a one-way valve. The air can only be discharged outward through the speed limiting hole 303, thereby achieving a deceleration effect, extending the opening time of the steel glass shutter 102, and ensuring that the shutdown is completed after the steel glass shutter 102 is opened.

[0055] Specific usage and function of this embodiment: In the present invention, during detection, the memory stick is directly inserted from the top of the memory detector 5, and the guide wheel 601 in the insertion aid device 6 assists in guiding so that the memory stick moves downward smoothly;

[0056] The memory stick is pressed down. When the memory stick contacts the L-shaped structure outside the trigger 505, the trigger 505 is driven down as a whole, and then the trigger 505 is used to approach the connecting frame A503. At this time, the spring outside the guide rod B502 provides a certain reaction force. When the trigger 505 is lowered to completely wrap the connecting frame A503, the connecting frame A503 and the trigger 505 are no longer fitted with an inclined surface, but with a flat surface. Figure 8 The trigger 505 is stuck with the weight of the memory stick, and at the same time, the two sets of connecting frames A503 are close to each other, pushing the micro contacts A504 to contact each set of copper pins of the memory stick. Each set of micro contacts A504 will adaptively connect to different copper pins and help stabilize the memory stick.

[0057] On the contrary, after the memory module is removed, the connection frame A503 and the trigger 505 will automatically reset through the spring;

[0058] When testing the hard disk, first pull open the self-locking lever 801, then place the slot-type hard disk into the auxiliary guide seat 8, with the copper feet of the slot-type hard disk facing the hard disk detector 7, release the self-locking lever 801, and the spring outside the self-locking lever 801 pushes the hard disk into the hard disk detector 7;

[0059] The hard disk detector 7 contacts the trigger frame 703 and squeezes the trigger frame 703 backward, and then uses the trapezoidal legs 704 to force the connection frames B706 on both sides to move closer, and uses the micro-contact B707 to adaptively contact the copper feet of the hard disk to achieve connection; the micro-contact B707 and the micro-contact A504 are made of soft metal with round heads to avoid wearing the copper feet;

[0060] The handle is used to push the transparent steel glass shield 102 backward, and the transparent steel glass shield 102 drives the trigger block 103 to move backward. When the transparent steel glass shield 102 is closed and connected to the assembly plate 4, the trigger block 103 contacts the external power button 2 to trigger the power on and perform the test. During this period, the hard disk and the memory stick cannot be directly removed. When the test is completed or the hard disk and the memory stick are to be removed, the transparent steel glass shield 102 is pulled back forward, and the trigger block 103 contacts the external power button 2 again to trigger the power off, thereby ensuring that the hard disk and the memory stick cannot be removed during the test.

[0061] When the steel-transmitting glass shutter 102 is closed, the piston rod 304 will also be stretched. When the piston rod 304 is extended, air is sucked through the damper 3, and the air directly opens the one-way plate 302 to move backward for replenishment. The resistance in this process is extremely small. On the contrary, when the steel-transmitting glass shutter 102 is opened, the one-way plate 302 is hindered by the reverse thrust and is closed by the air pressure to form a one-way valve. The air can only be discharged outward through the speed limiting hole 303, thereby achieving a deceleration effect, extending the opening time of the steel-transmitting glass shutter 102, and ensuring that the shutdown is completed after the steel-transmitting glass shutter 102 is opened.
