Description

Technical Field

[0001] This utility model relates to the field of electronic device testing, and more specifically, to an electronic device life testing device. Background Technology

[0002] In the manufacturing process of electronic products, due to the complex processing and extensive use of components, both processing defects and component defects can be categorized into obvious defects and potential defects. Obvious defects refer to those that cause the product to malfunction, such as short circuits / open circuits. Potential defects allow the product to be used temporarily, but the defects will quickly become apparent during use, causing the product to malfunction. Potential defects cannot be detected by conventional inspection methods and are instead eliminated using aging methods. Aging testing involves continuously applying environmental stress to components at a certain ambient temperature for an extended period of time. Environmental stress screening includes not only high-temperature stress but also many other stresses, such as temperature cycling and random vibration. Through the combined effect of electrothermal stress, various physical and chemical reactions within the components are accelerated, causing various potential defects hidden within the components to be exposed early, thereby achieving the goal of eliminating products that fail early. In the prior art, a device for testing the aging of automotive electronic components, with application number 202322728864.2, relates to the field of electronic component aging testing technology. It includes a base with a groove formed on the outer surface of the base. Telescopic springs are fixedly installed at the four corners of the lower inner surface of the groove. A drive motor assembly is fixedly installed in the center of the lower inner surface of the groove. A telescopic rod is rotatably mounted on the surface of the drive motor assembly via a bearing. A first ring plate is rotatably mounted on the outer sleeve surface of the telescopic rod via a bearing. Compared with existing ordinary automotive electronic component aging testing devices, this device generates vibration force through shaking, avoiding collision-type friction, reducing wear, and extending service life. Furthermore, the shaking mechanism at the center, in conjunction with the telescopic springs at the four corners, ensures more comprehensive vibration force transmission, avoiding excessive vibration in the center and weak vibration at the edges, thus improving the accuracy of vibration testing.

[0003] The applicant's research revealed certain shortcomings in the aforementioned solution. During operation, the device uses rubber pads to secure electronic components. These rubber pads are continuously exposed to high temperatures. Due to the inherent properties of the rubber material, they may harden, crack, and lose elasticity after a period of use under high temperatures, affecting the device's securing effect. Furthermore, the device does not allow for easy disassembly and replacement of the rubber pads, potentially reducing its effectiveness. Addressing these issues has become a pressing problem for those skilled in the art. Utility Model Content

[0004] To overcome the above shortcomings, this utility model provides an electronic device life testing device, which aims to improve the device's operation. When the device fixes the electronic device with a rubber pad, the rubber pad is continuously exposed to high temperatures. Due to the characteristics of the rubber pad itself, it may harden, crack, and lose elasticity after a period of use under high temperature conditions, thus affecting the device's fixing effect. Furthermore, the device is not convenient for disassembling and replacing the rubber pad, which may reduce the device's fixing effect.

[0005] This utility model is implemented as follows: an electronic device life testing device includes a housing, a heater installed on the inner wall of the housing, a vibration mechanism installed on the inner wall of the housing, a position adjustment mechanism installed inside the vibration mechanism, an installation mechanism installed on one side of the position adjustment mechanism, and a limit mechanism detachably installed on one side of the installation mechanism.

[0006] In a preferred embodiment of this utility model, the vibration mechanism includes a mounting plate, which is mounted on the inner wall of the housing. An elastic body is mounted on the upper end of the mounting plate, and a placement plate is mounted on the other end of the elastic body. An electromagnetic vibrator is mounted on the bottom end of the placement plate, and a slider is mounted on one side of the placement plate. A sliding groove is provided on the inner side of the housing to cooperate with the slider.

[0007] In a preferred embodiment of this utility model, a placement pad is installed on the upper end of the placement plate, and a slider is slidably connected in the groove to improve the stability of the placement plate when it moves. The placement plate is vibrated by an electromagnetic vibrator in conjunction with an elastic body, so that the electronic devices placed on the placement pad can be subjected to vibration testing.

[0008] In a preferred embodiment of this utility model, the position adjustment mechanism includes a second mounting plate. The mounting plate has a groove, and the second mounting plate is installed at the inner end of the groove. A motor is installed on one side of the second mounting plate, and a lead screw is rotatably installed on the other side of the second mounting plate. The lead screw is driven by the motor, and a moving plate is threaded onto the lead screw. A guide block is installed on one side of the moving plate, and a guide groove is provided on the inner wall of the groove in cooperation with the guide block. The guide block is slidably connected in the guide groove to improve the stability of the moving plate when it moves. Two sets of grooves and position adjustment mechanisms are provided and symmetrically arranged. The moving plate is moved by the motor driving the lead screw.

[0009] In a preferred embodiment of this utility model, the installation mechanism includes an installation block mounted on one side of the movable plate. The installation block is provided with an installation groove, a connecting groove, and a slot. A threaded rod is rotatably mounted inside the installation groove, and a movable sleeve is threaded onto the outer wall of the threaded rod. The movable sleeve slides through the installation groove and the slot. The limiting mechanism includes a limiting elastic plate. A connecting plate is mounted on one side of the limiting elastic plate. The shape and size of the connecting plate are matched with the connecting groove. An insert plate is mounted on the upper end of the connecting plate. The slot is matched with the shape and size of the insert plate. A fixing groove is provided on one side of the insert plate to match the movable sleeve. When the limiting mechanism is installed, the limiting elastic plate is connected to the connecting groove. The connecting plate and insert plate are initially fixed by inserting them into the side of the connecting groove and slot. The insertion of the connecting plate and insert plate together ensures strong installation stability. The rotation of the threaded rod causes the moving sleeve to move and fix the insert plate in the fixing groove, thus completing the installation of the limiting elastic plate. When using the limiting elastic plate, to avoid damage to electronic components, the elastic plate is generally made of rubber, silicone, or fluororubber. Due to the nature of the elastic plate material itself, it will be affected by high temperatures. When the limiting elastic plate has been used for a certain period of time and is affected by high temperatures, it may soften, deform, wear severely, and reduce the limiting effect and elasticity. In this case, the limiting mechanism can be disassembled and replaced. After replacement, it can be easily and quickly reinstalled.

[0010] In a preferred embodiment of this utility model, an auxiliary rod is installed at one end of the movable sleeve, and an auxiliary groove is provided in the inner end of the mounting groove in cooperation with the auxiliary rod. The auxiliary rod is slidably connected in the auxiliary groove to improve the stability of the movable sleeve when it moves.

[0011] In a preferred embodiment of this utility model, a second mounting block is mounted on the upper end of the mounting block. The second mounting block has a mounting cavity that is connected to the mounting groove. A rod is rotatably mounted inside the second mounting block. A worm gear is mounted on one end of the rod. A worm wheel is fixedly sleeved on the outer wall of the threaded rod. The worm wheel and the worm gear are meshed. Rotation of the rod causes the worm gear to drive the worm wheel to rotate, thereby causing the threaded rod to rotate. At the same time, the self-locking property of the worm gear prevents the threaded rod from rotating in the opposite direction, thus enhancing the installation stability of the limiting mechanism.

[0012] In a preferred embodiment of this utility model, the rod rotates through one end of the second mounting block, and an external support is mounted on one end of the rod.

[0013] In a preferred embodiment of this utility model, a temperature sensor is provided at the inner end of the box, and an air inlet pipe and an air vent valve are connected to one side of the box. The air inlet pipe is equipped with a valve, and the box is heated by a heater to perform high-temperature testing on electronic devices.

[0014] In a preferred embodiment of this utility model, a frame is sealed and hinged to one side of the box body, a handle is installed on one side of the frame body, and an observation window is provided on the inner wall of the frame body.

[0015] The beneficial effects of this utility model are as follows: The electronic device lifespan testing device obtained through the above design, in use, uses a motor-driven lead screw to move a movable plate, thereby fixing the electronic device with two sets of limiting elastic plates. An electromagnetic vibrator, in conjunction with an elastic body, vibrates the placement plate, causing the electronic device placed on the placement pad to undergo vibration testing. A heater heats the chamber, conducting high-temperature testing on the electronic device. When the limiting elastic plates soften, deform, or become severely worn due to high temperatures after a certain period of use, resulting in reduced limiting effect and decreased elasticity, the limiting elastic plates need to be disassembled and replaced. Rotating the rod with an external holder causes the worm gear to drive the worm wheel, which in turn rotates the threaded rod, causing the movable sleeve to move and no longer fix the insert plate in the fixing slot. The connecting plate and insert plate are then pulled out of the connecting slot and slot, replaced, and reinstalled, ensuring the device's fixing effect. This device can detect high temperature and vibration of electronic devices, and can effectively fix the electronic devices during the test. At the same time, the installation mechanism can quickly and easily disassemble and install the limiting mechanism, saving time during operation and ensuring the fixation effect.

Obviously, the described embodiments are only some embodiments of this utility model, not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

[0020] Please see Figures 1-4 The present invention provides a technical solution: an electronic device life test device, including a housing 100, a heater 120 installed on the inner wall of the housing 100, a vibration mechanism 200 installed on the inner wall of the housing 100, a position adjustment mechanism 300 installed on the inner side of the vibration mechanism 200, an installation mechanism 400 installed on one side of the position adjustment mechanism 300, and a limit mechanism 500 detachably installed on one side of the installation mechanism 400.

[0021] In some specific implementations, the vibration mechanism 200 includes a mounting plate 210, which is mounted on the inner wall of the housing 100. An elastic body 220 is mounted on the upper end of the mounting plate 210, and a placement plate 230 is mounted on the other end of the elastic body 220. An electromagnetic vibrator 250 is mounted on the bottom end of the placement plate 230, and a slider 240 is mounted on one side of the placement plate 230. A groove is provided on the inner side of the housing 100 to cooperate with the slider 240.

[0022] In some specific implementations, a placement pad 260 is installed on the upper end of the placement plate 230, and a slider 240 is slidably connected in the groove to improve the stability of the placement plate 230 when it moves. The placement plate 230 is vibrated by an electromagnetic vibrator 250 in conjunction with an elastic body 220, so that the electronic devices placed on the placement pad 260 can be subjected to vibration testing.

[0023] In some specific implementations, the position adjustment mechanism 300 includes a second mounting plate 310, a placement plate 230 with a groove 231, the second mounting plate 310 being installed inside the groove 231, a motor 320 being installed on one side of the second mounting plate 310, and a lead screw 330 being rotatably installed on the other side of the second mounting plate 310. The lead screw 330 is driven by the motor 320, and a moving plate 340 is threaded onto the lead screw 330. A guide block 350 is installed on one side of the moving plate 340, and a guide groove is provided on the inner wall of the groove 231 in conjunction with the guide block 350. The guide block 350 is slidably connected in the guide groove to improve the stability of the moving plate 340 during movement. Two sets of grooves 231 and position adjustment mechanisms 300 are provided and symmetrically arranged. The moving plate 340 is moved by the motor 320 driving the lead screw 330.

[0024] In some specific implementations, the installation mechanism 400 includes an installation block 410, which is installed on one side of the movable plate 340. The installation block 410 is provided with an installation groove 411, a connecting groove 412, and a slot 413. A threaded rod 420 is rotatably installed inside the installation groove 411, and a movable sleeve 430 is threadedly installed on the outer wall of the threaded rod 420. The movable sleeve 430 slides through the installation groove 411 and the slot 413. The limiting mechanism 500 includes a limiting elastic plate 510, with a connecting plate 520 installed on one side of the limiting elastic plate 510.

The shape and size of the slot 413 are matched with the insert plate 530. A fixing groove 531 is provided on one side of the insert plate 530 to match the movable sleeve 430. When the limiting mechanism 500 is installed, the limiting elastic plate... The 510 is initially fixed by inserting the connecting plate 520 and the insert plate 530 into the side of the connecting groove 412 and the slot 413. The insertion of the connecting plate 520 and the insert plate 530 ensures strong installation stability. The rotation of the threaded rod 420 causes the moving sleeve 430 to move and fix the insert plate 530 in conjunction with the fixing groove 531, thus completing the installation of the limiting elastic plate 510. When using the limiting elastic plate 510, to avoid damage to electronic components, it is generally made of rubber, silicone, or fluororubber. Due to the nature of the elastic plate material, it is affected by high temperatures. When the limiting elastic plate 510 is used for a certain period of time and is affected by high temperatures, it softens, deforms, wears severely, and the limiting effect and elasticity decrease. In this case, the limiting mechanism 500 can be disassembled and replaced. After replacement, it can be easily and quickly reinstalled.

[0025] In some specific implementations, an auxiliary rod 440 is installed at one end of the movable sleeve 430, and an auxiliary groove is provided in the inner end of the mounting groove 411 to cooperate with the auxiliary rod 440. The auxiliary rod 440 is slidably connected in the auxiliary groove to improve the stability of the movable sleeve 430 when it moves.

[0026] In some specific implementations, a second mounting block 490 is mounted on the upper end of the mounting block 410. The second mounting block 490 is provided with a mounting cavity and the mounting cavity is connected to the mounting groove 411. A rod 460 is rotatably mounted inside the second mounting block 490. A worm 470 is mounted on one end of the rod 460. A worm wheel 450 is fixedly sleeved on the outer wall of the threaded rod 420. The worm wheel 450 and the worm 470 are meshed. The rotation of the rod 460 causes the worm 470 to drive the worm wheel 450 to rotate, which in turn causes the threaded rod 420 to rotate. At the same time, the self-locking property of the worm 470 prevents the threaded rod 420 from rotating in the opposite direction, thereby enhancing the installation stability of the limiting mechanism 500.

[0027] In some specific implementations, the rod 460 rotates through one end of the second mounting block 490, and an external support 480 is mounted on one end of the rod 460.

[0028] In some specific implementation schemes, a temperature sensor 150 is provided inside the enclosure 100, and an air inlet pipe 130 and an air vent valve 140 are connected to one side of the enclosure 100. The air inlet pipe 130 is equipped with a valve 131, and the inside of the enclosure 100 is heated by a heater 120 to perform high-temperature testing on electronic devices.

[0029] In some specific implementations, a frame 110 is sealed and hinged to one side of the housing 100, a handle 112 is installed on one side of the frame 110, and an observation window 111 is provided on the inner wall of the frame 110.

[0030] Working principle: During use, the motor 320 drives the lead screw 330 to move the moving plate 340, thereby fixing the electronic components with two sets of limiting elastic plates 510. The electromagnetic vibrator 250, in conjunction with the elastic body 220, vibrates the placement plate 230, causing the electronic components placed on the placement pad 260 to undergo vibration testing. The heater 120 heats the inside of the housing 100 to conduct high-temperature testing on the electronic components. When the limiting elastic plates 510 are used for a certain period of time and subjected to high temperatures, they soften. When deformation, wear, and severe wear reduce the limiting effect and elasticity, the limiting elastic plate 510 needs to be disassembled and replaced. By rotating the rod 460 through the external holding 480, the worm 470 drives the worm wheel 450 to rotate, causing the threaded rod 420 to rotate, which in turn causes the moving sleeve 430 to move and no longer cooperate with the fixing groove 531 to fix the insert plate 530. The connecting plate 520 and the insert plate 530 are then pulled out from the connecting groove 412 and the slot 413, replaced, and reinstalled to ensure the fixing effect of the device.

[0031] The above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Various modifications and variations can be made to this utility model by those skilled in the art. Any modifications, equivalent substitutions, or improvements made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
