At the same time, the third slider 407 drives the clamping arm 411 to move. When the clamping arm 411 moves to the appropriate position, it clamps the electronic module. Then, the console 2 is operated to start the first motor 401 and the second motor. 402. According to the test command set on the console 2, the first motor 401 drives the first lead screw 403 to rotate, and the first lead screw 403 drives the first slider 405 to move linearly. At the same time, the second motor 402 drives the second lead screw 404 to rotate, and the second lead screw 404 drives the second slider 406 to move linearly. At this time, one end of the electronic module is in contact with the strain gauge 409. The test command set on the console 2 controls the pressure on the contact surface between the electronic module and the strain gauge 409. By measuring the resistance change of the strain gauge 409, the strain of the electronic module is calculated and the test data is viewed on the integrated display screen of the console 2. At this time, the stress test of the electronic module is completed.

[0027] Furthermore, one end of the first motor 401 is fixedly connected to the first lead screw 403, and one end of the second motor 402 is fixedly connected to the second lead screw 404. Through the setting of the first motor 401, the first motor 401 drives the first lead screw 403 to rotate, thereby causing the first lead screw 403 to drive the first slider 405 to move linearly.

[0028] Furthermore, one end of the first slider 405 is fitted inside the base 1, and one end of the second slider 406 is fitted inside the base 1. By setting the first slider 405 so that one end of the first slider 405 is fitted inside the base 1, the first slider 405 moves more stably.

[0029] Furthermore, the clamping arm 411 is installed on one side of the surface of the second slider 406, and the rotating shaft 414 passes through the second slider 406 and is fixedly connected to the third motor 408. Through the setting of the clamping arm 411, the clamping arm 411 can clamp the electronic module and can be adjusted according to different models of electronic modules.

[0030] Furthermore, two sets of the first motor 401 and two sets of the second motor 402 are provided. The second motor 402 drives the second lead screw 404 to rotate, thereby causing the second lead screw 404 to drive the second slider 406 to move linearly.

[0031] Furthermore, the early warning mechanism 5 includes a mounting plate 501, a first warning light 502 mounted on one side of the surface of the control console 2, a second warning light 503 mounted on one side of the surface of the control console 2, an alarm 504 mounted on one side of the surface of the control console 2, a groove 505 formed on one side of the surface of the mounting plate 501, a pressure plate 506 fixedly connected to one side of the surface of the mounting plate 501, a temperature sensor 507 mounted on one side of the surface of the mounting plate 501, a connecting pipe 508 mounted on one side of the surface of the temperature sensor 507, and a through hole 509 formed inside the connecting pipe 508. Through the arrangement of the mounting plate 501, the first warning light 502, the second warning light 503, the alarm 504, the groove 505, the pressure plate 506, the temperature sensor 507, the connecting pipe 508, and the through hole 509, during testing, the temperature warning range of the strain gauge 409 is first set through the control console 2. The probe at one end of the temperature sensor 507 passes through the connecting pipe 508 and contacts the strain gauge 409. Then, the temperature sensor 507 feeds back the monitored data to the control console 2. When the set temperature range is exceeded... When the temperature drops below the set range, the first warning light 502, which is electrically connected to the control panel 2, illuminates and triggers an alarm via the alarm 504. When the temperature drops below the set range, the second warning light 503, also electrically connected to the control panel 2, illuminates and triggers an alarm via the alarm 504. At this time, the temperature of the strain gauge 409 is detected to prevent the resistance value of the strain gauge 409 from affecting the accuracy of the test. When other data of the strain gauge 409 needs to be monitored, the mounting plate 501 can be removed from one side of the surface of the second slider 406 by pressing down on the pressure plate 506. Then, the temperature sensor 507 is unscrewed from the connecting tube 508, and the replacement device is reinstalled inside the second slider 406 and connected to the control panel 2. At this time, the strain gauge 409 can be monitored as needed. Due to the groove 505, when the mounting plate 501 is installed, one end of the mounting plate 501 can be fitted into the groove 505, thus limiting one end of the mounting plate 501. Due to the through hole 509, the temperature sensor 507 can pass its probe through the through hole 509 and the second slider 406 to contact the strain gauge 409.

[0032] Furthermore, one side of the surface of the temperature sensor 507 is threadedly connected to the connecting pipe 508, and one end of the temperature sensor 507 passes through the through hole 509. The through hole 509 allows the probe at one end of the temperature sensor 507 to pass through the through hole 509 and the second slider 406 to contact the strain gauge 409.

[0033] Working principle: When the testing device is in use or idle, firstly, pull up the handle 305 to lift the second dust cover 302. The second dust cover 302 moves under the force of the handle 305. Then, the first dust cover 301 and the second dust cover 302 are closed, so that the first sealing strip 304 and the second sealing strip 306 are tightly fitted. Next, the first dust cover 301 and the second dust cover 302 are locked together by the latch lock 307, thereby fixing the first dust cover 301 and the second dust cover 302. At this time, the testing device is covered by the first dust cover 301 and the second dust cover 302 for dust protection. The setting of the round shaft 303 allows the second dust cover 302 to be installed on one side of the surface of the base 1, and the second dust cover 302 is supported by the handle 305. The device is movable under force. Through the tempered glass 308, the testing process can be observed during use. For strain testing, the electronic module is first placed on one side of the second slider 406 surface. Then, the third motor 408 is started via the control console 2. The third motor 408 drives the rotating shaft 414, which in turn drives the second moving block 413. The second moving block 413 then drives the first moving block 412, which in turn drives the shaft 410. The shaft 410 then drives the third slider 407 to slide inside the second slider 406. Simultaneously, the third slider 407 drives the clamping arm 411. When the clamping arm 411 reaches the appropriate position, it clamps the electronic module. Afterwards, the control console is operated. 2. Start the first motor 401 and the second motor 402. Following the test commands set on the control console 2, the first motor 401 drives the first lead screw 403 to rotate, which in turn drives the first slider 405 to move linearly. Simultaneously, the second motor 402 drives the second lead screw 404 to rotate, which in turn drives the second slider 406 to move linearly. At this point, one end of the electronic module contacts the strain gauge 409. The test commands set on the control console 2 control the pressure at the contact surface between the electronic module and the strain gauge 409. By measuring the resistance change of the strain gauge 409, the strain of the electronic module is calculated, and the test data is viewed on the integrated display screen of the control console 2. This completes the stress test of the electronic module. During the test, the temperature preset of the strain gauge 409 is first set on the control console 2. In the alarm zone, the probe of one end of the temperature sensor 507 passes through the connecting tube 508 and contacts the strain gauge 409. The temperature sensor 507 then feeds back the monitored data to the control console 2. When the temperature exceeds the set temperature range, the first warning light 502, electrically connected to the control console 2, illuminates and an alarm 504 is triggered. When the temperature falls below the set temperature range, the second warning light 503, also electrically connected to the control console 2, illuminates and an alarm 504 is triggered. At this time, the temperature of the strain gauge 409 is detected to prevent the resistance value of the strain gauge 409 from affecting the accuracy of the test. When it is necessary to monitor other data of the strain gauge 409, the mounting plate 501 can be removed from one side of the surface of the second slider 406 by pressing down the pressure plate 506. Then, the temperature sensor 507 can be unscrewed from the connecting tube 508.The replaced equipment is then reinstalled inside the second slider 406 and connected to the control console 2. At this point, the strain gauge 409 can be monitored as needed. Due to the groove 505, one end of the mounting plate 501 can be fitted into the groove 505 during installation, thus limiting the position of one end of the mounting plate 501. The through hole 509 allows the temperature sensor 507 to pass its probe through the through hole 509 and contact the strain gauge 409 with the second slider 406.
