[0033] 700, Dual In-line Memory Module Under Test; 710, Channel. Detailed Implementation

[0034] The present invention will be further described below with reference to the accompanying drawings and specific embodiments, so that those skilled in the art can better understand and implement the present invention. However, the embodiments are not intended to limit the present invention.

[0035] Reference Figures 1-4 As shown, this utility model embodiment provides a device for detecting leakage of dual in-line memory modules, including a connecting frame 100, an air intake sealing mechanism 200, a clamping mechanism 300, at least two positioning mechanisms 400, a straightening mechanism 500, and a reset mechanism 600.

[0036] The connecting frame 100 includes a base 110 and a plurality of support legs 120 connected to the bottom of the base 110;

[0037] The air intake sealing mechanism 200 includes a first sealing element 210; the first sealing element 210 is provided with an air intake hole 211 that penetrates its thickness, and the air intake hole 211 communicates with the channel 710 on the dual in-line memory module 700 to be tested;

[0038] The clamping mechanism 300 and the air intake sealing mechanism 200 are symmetrically connected at both ends of the base 110; the clamping mechanism 300 includes a clamping power unit 310 and a second sealing member 320 connected to the output end of the clamping power unit 310; the clamping power unit 310 drives the second sealing member 320 to move in the X direction to seal the dual in-line memory module 700 under test between the first sealing member 210 and the second sealing member 320, where the X direction is the extension direction of the dual in-line memory module 700 under test;

[0039] At least two positioning mechanisms 400 are spaced apart between the air intake sealing mechanism 200 and the clamping mechanism 300; the positioning mechanism 400 is connected to the base 110; the top of the positioning mechanism 400 is provided with a positioning groove 410 for placing the dual in-line memory module 700 to be tested; the positioning groove 410 is an L-shaped groove; the top of the positioning groove 410 and the side facing the alignment mechanism 500 (described below) are provided with openings;

[0040] Along the Y-direction, the alignment mechanism 500 and the positioning mechanism 400 are respectively located on both sides of the dual in-line memory module 700 to be tested; the Y-direction is the width direction of the dual in-line memory module 700 to be tested; the alignment mechanism 500 includes an alignment component 510 that moves along the Y-direction. The alignment mechanism 500 also includes an alignment cylinder 520, the output end of which is connected to the alignment component 510 to drive the alignment component 510 to translate in the Y-direction;

[0041] The reset mechanism 600 is connected to the base 110 to drive the dual in-line memory module 700 under test to move and reset in the X direction.

[0042] Specifically, in this embodiment, the dual in-line memory module 700 to be tested is placed on the positioning mechanism 400 (i.e., the loading position). Then, the alignment mechanism 500 corrects the dual in-line memory module 700 to ensure that the channel 710 of the dual in-line memory module 700 is aligned with the air inlet 211. Then, the clamping power unit 310 drives the second seal 320 to move towards the air inlet sealing mechanism 200, so that the dual in-line memory module 700 to be tested is sealed between the first seal 210 and the second seal 320. Thus, the air inlet sealing mechanism 200 applies high-pressure gas to the channel 710 of the dual in-line memory module 700 to detect leaks. After the test is completed, the clamping mechanism 300 moves in the reverse direction, and then the reset mechanism 600 drives the dual in-line memory module 700 to be tested back to the loading position. Therefore, this application can perform automated testing of the dual in-line memory module 700 under test, with high testing accuracy and reduced misjudgment; it eliminates the need for manual testing, reducing labor costs and improving efficiency.

[0043] Furthermore, the reset mechanism 600 is located between the two positioning mechanisms 400; the aligning component 510 is provided with a clearance groove 511 for avoiding the reset mechanism 600.

[0044] Specifically, since the dual in-line memory module 700 under test has a thin-walled, elongated plate-like structure, it is prone to deformation and displacement during movement. In this embodiment, the reset mechanism 600 is located between the two positioning mechanisms 400. Thus, when the reset mechanism 600 moves the dual in-line memory module 700 under test for translational reset, both ends of the dual in-line memory module 700 under test are supported by the positioning mechanisms 400, preventing deformation and displacement of the dual in-line memory module 700 under test during the resetting process.

[0045] Further, the reset mechanism 600 includes a material pulling component 610 and a clamping component 620 slidably connected to the top of the material pulling component 610; the material pulling component 610 is connected to the base 110, and the output end of the material pulling component 610 is connected to the clamping component 620; the clamping component 620 is used to clamp the dual in-line memory module 700 to be tested; the material pulling component 610 drives the clamping component 620 to translate, so that the dual in-line memory module 700 to be tested is reset. In some embodiments, the material pulling component 610 includes a cylinder.

[0046] Specifically, in this embodiment, the clamping component 620 clamps the dual in-line memory module 700 to be tested, and then the pulling component 610 drives the clamping component 620 and the dual in-line memory module 700 to be tested to translate, thereby resetting the dual in-line memory module 700 to be tested; the structure is simple and the cost is low.

[0047] Furthermore, the clamping component 620 includes a gripper cylinder 621 and two clamping blocks 622; the gripper cylinder 621 is connected to the material pulling component 610, and the two output ends of the gripper cylinder 621 are respectively connected to the two clamping blocks 622; the gripper cylinder 621 drives the two clamping blocks 622 to open and close in the width direction of the dual in-line memory module 700 to be tested, so as to clamp the dual in-line memory module 700 to be tested.

[0048] Specifically, this application uses two clamping blocks 622 to clamp the dual in-line memory module 700 under test, which can provide appropriate clamping force and facilitate quick clamping.

[0049] Furthermore, L-shaped grooves are provided on the opposing sides of the two clamping blocks 622.

[0050] Specifically, in this embodiment, the dual in-line memory module 700 under test can be limited by an L-shaped slot to prevent the dual in-line memory module 700 under test from shifting during the reset process.

[0051] Furthermore, the reset mechanism 600 also includes a first sensor 630 for monitoring whether the dual in-line memory module 700 under test has been reset. In some embodiments, the first sensor 630 is a photoelectric sensor, which includes a main body end 632 and a trigger end 631; the main body end 632 is connected to the base 110, and the trigger end 631 is connected to one side of the clamping member 620. By contacting the main body end 632 with the trigger end 631, the travel distance of the clamping member 620 is monitored, thereby determining whether the dual in-line memory module 700 under test has been reset.

[0052] Specifically, the first sensor 630 in this embodiment can determine whether the dual in-line memory module 700 under test has completed its reset, thereby achieving automation. In some embodiments, this application also includes a control unit, which is connected to the sensor, the clamping component 620, the pulling component 610, and the robot arm for the next process. When the control unit receives a reset notification from the sensor, the control unit controls the pulling component 610 to stop moving the clamping component 620; controls the clamping component 620 to open the two clamping blocks 622 to release the dual in-line memory module 700 under test; and controls the robot arm to move to grab the dual in-line memory module 700 under test and transport it to the next process.

[0053] Furthermore, the positioning mechanism 400 also includes a material sensor 420; the material sensor 420 is located on one side of a positioning mechanism 400 and is used to monitor whether a dual in-line memory module 700 to be tested is placed on the positioning mechanism 400.

[0054] Specifically, this embodiment can identify whether a dual in-line memory module 700 to be tested is placed on the positioning mechanism 400, thereby facilitating subsequent work.

[0055] Furthermore, the tightening mechanism 300 also includes a tightening sealing block 330, one end of which is connected to the output end of the tightening power unit 310 and the other end is connected to the second sealing member 320; at the end of the tightening sealing block 330 that abuts with the second sealing member 320, at least two arc-shaped connecting protrusions 331 are provided; the at least two arc-shaped connecting protrusions 331 are evenly distributed circumferentially; the second sealing member 320 is sandwiched in the at least two arc-shaped connecting protrusions 331.

[0056] Specifically, in this embodiment, the second seal 320 is clamped by at least two arc-shaped connecting protrusions 331. Since the second seal 320 is an elastic seal, the connection is stable and reliable, and the first seal 210 is easy to install and remove quickly.

[0057] Furthermore, the intake sealing mechanism 200 includes an intake body 220 and a sealing connector 230; a first seal 210 is connected to the intake body 220; the intake body 220 is provided with an intake channel 221, one end of the intake channel 221 is located on the side wall of the intake body 220, and the other end is connected to the intake hole 211; one end of the sealing connector 230 is connected to the intake body 220, and the other end is provided with a groove 231, and the first seal 210 is installed in the groove 231.

[0058] Furthermore, in the air intake channel 221, one end located on the side wall of the air intake body 220 is connected to the leak detector; a valve body 240 is provided at the connection position.

[0059] Specifically, in this embodiment, the valve body 240 controls the opening and closing of the leak detector and the air intake sealing mechanism 200.

[0060] The specific testing process is as follows:

[0061] After the material sensor 420 detects the presence of material, the alignment cylinder 520 aligns the dual-in-line memory module 700 to be tested; the clamping power unit 310 extends to clamp the dual-in-line memory module 700 to be tested; the test begins, the valve body 240 opens, and high-pressure gas enters the air inlet channel 221, air inlet 211 and channel 710 sequentially from the leak detector to perform pressure holding and leakage detection. After the test is completed, the clamping power unit 310 retracts, the gripper cylinder 621 clamps the dual-in-line memory module 700 to be tested, and the material pulling component 610 pulls the product back to the loading position.

[0062] Obviously, the above embodiments are merely illustrative examples for clear explanation and are not intended to limit the implementation. Those skilled in the art will recognize that other variations or modifications can be made based on the above description. It is neither necessary nor possible to exhaustively list all possible implementations here. However, obvious variations or modifications derived therefrom are still within the protection scope of this invention.
