Description

Technical Field

[0001] This utility model relates to the field of aging equipment technology, specifically to a high-temperature aging equipment for crystal oscillators. Background Technology

[0002] Aging tests are a common quality control method in engineering, designed to eliminate potentially failing products by simulating extreme operating conditions, thereby improving the reliability of the entire system. In actual production, due to various uncertainties such as materials, processes, and environment, even products from the same batch can have varying reliability of their internal components. To ensure high quality and reliability of the final product delivered to the user, manufacturers typically conduct aging tests on components before assembly and packaging. This process involves applying stresses such as current, voltage, and temperature to components over a specific period to accelerate the exposure of potential defects, effectively eliminating defective or substandard products and ensuring the reliability of the final product.

[0003] The currently used high-temperature aging equipment has a significant problem when heating and testing crystal oscillators: if some crystal oscillators are damaged during the test, some will produce a burnt smell. When testing the next batch of crystal oscillators, if the aging equipment is turned on directly, the residual burnt smell inside the equipment will drift into the operating environment with the airflow, affecting the testing environment. At the same time, because the equipment may have residual heat from the previous test or uneven heat distribution, turning on the equipment will cause the heat to dissipate rapidly, requiring a longer time to reheat the equipment to the required testing temperature. This not only increases energy consumption but also significantly reduces the overall efficiency of crystal oscillator aging tests. Utility Model Content

[0004] This invention provides a high-temperature aging device for crystal oscillators. By incorporating a storage component and a processing mechanism, the air is processed and stored for reuse, thereby improving testing efficiency.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a high-temperature aging equipment for crystal oscillators, comprising an aging chamber, a storage component, a processing mechanism, an extraction pump, and a test board;

[0006] The test board is assembled inside the old refining chamber;

[0007] The air inlet of the processing mechanism is connected to the aging chamber, and the processing mechanism circulates the processed gas into the interior of the aging chamber through a pump and storage device.

[0008] When the extraction pump is used, the aging chamber is closed, and the gas inside the aging chamber is processed by the processing mechanism. If there is a blockage in the processing mechanism, the gas flow path is switched and the blocked parts are self-cleaned.

[0009] Preferably, the storage component includes a storage box, an exhaust pipe, and a valve. The air inlet of the storage box is connected to the exhaust port of the extraction pump via a pipeline, and the storage box is connected to the aging tank via the exhaust pipe.

[0010] Preferably, the processing mechanism includes a box body, an auxiliary pipe, a filter plate, and an activated carbon filter. The bottom of the box body is connected to the aging chamber. The filter plate is slidably fitted inside the box body and has filter holes. The filter plate is connected to a removal component so that when the filter holes are blocked, the filter plate moves toward the removal component to remove impurities inside the filter holes. The activated carbon filter is installed at the top of the box body. The auxiliary pipe connects the middle and top of the box body so that when the filter plate moves toward the removal component, it unblocks the auxiliary pipe and discharges gas into the upper part of the removal component.

[0011] Preferably, the removal component includes a filter screen, a guide rod, a spring, and a removal tube. The filter screen is installed inside the housing, and the removal tube is installed on the filter screen and corresponding to the filter holes. One end of the guide rod is fixedly connected to the filter screen, and the other end slides through the filter holes. The spring is movably sleeved on the outer periphery of the guide rod, with one end connected to the filter screen and the other end connected to the filter plate.

[0012] Preferably, the auxiliary pipeline has an internal impurity adhesive attachment.

[0013] Preferably, the impurity adhesive attachment includes a rotating shaft and a rotating plate, the rotating plate is installed on the outer periphery of the rotating shaft, the rotating shaft is rotatably disposed inside the auxiliary pipe, and the rotating plate is coated with an adhesive layer.

[0014] The beneficial effects of this utility model are as follows:

[0015] 1. The filter plate's filter holes intercept impurities generated by crystal oscillator damage, while the activated carbon filter adsorbs odor molecules and volatile organic compounds, effectively eliminating burnt odors, preventing pollution of the operating environment, and improving working conditions for testing personnel. The adhesive layer of the rotating plate inside the auxiliary pipeline captures impurities, and combined with centrifugal force, further improves purification accuracy, ensuring clean exhaust gas.

[0016] 2. The storage tank is connected to the aging chamber via an exhaust pipe and a valve. During testing breaks or material changes, the purified high-temperature gas is stored in the storage tank to prevent heat loss with the exhaust. When restarting, the stored high-temperature gas is directly returned to the chamber, reducing heat loss, shortening the heating time, and improving testing efficiency.

[0017] 3. When the filter plate is clogged, the gas pressure difference pushes the filter plate to move, automatically opening the auxiliary pipeline and diverting the gas flow to avoid shutdown due to blockage. The auxiliary pipeline is designed in parallel with the main path to form a redundant purification channel, ensuring that the test process is not interrupted. When the filter plate moves, the removal tube is inserted into the filter hole to push out impurities for subsequent reuse. Attached Figure Description

[0024] The technical solution of this utility model will now be clearly and completely described with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, and 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 protection scope of this utility model.

[0025] according to Figures 1-4 As shown, a high-temperature aging equipment for crystal oscillators includes an aging chamber 1, a storage unit 2, a processing mechanism 3, an extraction pump 4, and a test board 5.

[0026] Test board 5 is assembled inside the old refining box 1;

[0027] The air inlet of the processing mechanism 3 is connected to the aging chamber 1. The processing mechanism 3 circulates the processed gas into the interior of the aging chamber 1 through the extraction pump 4 and the storage device 2.

[0028] When the extraction pump 4 extracts, the aging tank 1 is closed, and the gas inside the aging tank 1 is processed by the processing mechanism 3. If the gas becomes blocked in the processing mechanism 3, the gas flow path is switched and the blocked parts are self-cleaned.

[0029] It should be noted that the door of the old refurbishing chamber 1 is not opened, forming a closed space. After the extraction pump 4 is started, the internal gas is drawn into the processing mechanism 3. After filtration and purification, it is reintroduced into the chamber through the storage device 2 to achieve gas circulation. When the processing mechanism 3 is blocked by impurities, the gas flow resistance increases, triggering the backup path and activating the self-cleaning mechanism to maintain continuous system operation. This purifies the gas inside the chamber, removes odors and impurities caused by crystal oscillator damage, improves the testing environment, recycles hot gas, reduces heat loss, shortens heating time, reduces energy consumption, and improves testing efficiency.

[0030] In a specific embodiment, the storage device 2 includes a storage box 21, an exhaust pipe 22 and a valve 23. The air inlet of the storage box 21 is connected to the exhaust port of the extraction pump 4 through a pipeline, and the storage box 21 is connected to the aging box 1 through the exhaust pipe 22.

[0031] It should be noted that before the crystal oscillator is moved in or out, the extraction pump 4 discharges the processed gas into the storage box 21. When the box is closed, the storage box 21 temporarily stores the high-temperature gas. The high-temperature gas stored is returned to the aging box 1 through the exhaust pipe 22 by the valve 23 to replenish the heat in the box, reduce the heat loss during the test interval, and reduce the time to reach the required temperature again.

[0032] In a specific embodiment, the processing mechanism 3 includes a box body 31, an auxiliary pipe 32, a filter plate 33, and an activated carbon filter screen 34. The bottom of the box body 31 is connected to the aging chamber 1. The filter plate 33 is slidably sleeved inside the box body 31. The filter plate 33 has filter holes 331. The filter plate 33 is connected to a removal component so that when the filter holes 331 are blocked, the filter plate 33 moves toward the removal component to remove impurities inside the filter holes 331. The activated carbon filter screen 34 is installed at the top inside the box body 31. The auxiliary pipe 32 connects the middle and top of the box body 31 so that when the filter plate 33 moves toward the removal component, it releases the blockage of the auxiliary pipe 32 and discharges the gas into the upper part of the removal component.

[0033] It should be noted that the gas enters from the bottom of the box 31 and first passes through the filter holes 331 of the filter plate 33 to filter particulate impurities (smoke generated by crystal oscillator damage, and impurities in the smoke). The filtered gas rises and is adsorbed by activated carbon to remove odors and harmful gases. When the filter holes 331 are blocked by impurities, the gas pressure pushes the filter plate 33 to move towards the removal component, opening the auxiliary pipe 32. The gas then flows directly to the activated carbon filter screen 34 through the auxiliary pipe, avoiding interruption of the process.

[0034] In a specific embodiment, the removal component includes a filter screen 35, a guide rod 36, a spring 37, and a removal tube 38. The filter screen 35 is installed inside the housing 31, and the removal tube 38 is installed on the filter screen 35 and is correspondingly arranged with the filter hole 331. One end of the guide rod 36 is fixedly connected to the filter screen 35, and the other end slides through the filter hole 331. The spring 37 is movably sleeved on the outer periphery of the guide rod 36, with one end connected to the filter screen 35 and the other end connected to the filter plate 33.

[0035] It should be noted that when the filter plate 33 moves backward due to blockage, the spring 37 is compressed, the filter plate 33 moves along the guide rod 36 toward the filter screen 35, the removal tube 38 is inserted into the filter hole 331 to push out the internal impurities, after the blockage is cleared, the spring 37 rebounds, the filter plate 33 resets, and the main path filtration is restored.

[0036] In a specific embodiment, the auxiliary pipe 32 is provided with an impurity adhesive attachment, which includes a rotating shaft 6 and a rotating plate 7. The rotating plate 7 is installed on the outer periphery of the rotating shaft 6, and the rotating shaft 6 is rotatably disposed inside the auxiliary pipe 32. An adhesive layer is coated on the rotating plate 7.

[0037] When the gas passes through the auxiliary pipe 32, it pushes the rotating plate 7 to rotate around the rotating shaft 6. The impurities ejected from the filter hole 331 pass through the rotating plate 7 and are adhered by the adhesive layer.

[0038] The working principle includes the following steps:

[0039] Crystal loading: Place the crystal oscillator on the test board 5 inside the aging chamber 1 and close the door of the aging chamber 1. At this time, the valve 23 of the storage component 2 is closed, the storage box 21 does not store gas, and the filter plate 33 of the processing mechanism 3 is in the initial position under the action of the spring 37, blocking the auxiliary pipe 32. The gas only flows through the filter hole 331 of the filter plate 33.

[0040] Drive gas circulation: Start the extraction pump 4, and the suction force generated by it will draw the high-temperature gas in the aging chamber 1 into the processing mechanism 3 from the bottom of the box 31. The gas first passes through the filter holes 331 of the filter plate 33 to intercept impurities generated during crystal oscillator testing (such as burnt debris, metal particles, etc.). The filter plate 33 is connected to the filter screen 35 through the guide rod 36 and can slide along the guide rod 36. The filtered gas continues to rise and passes through the activated carbon filter screen 34 at the top of the box 31. The adsorption characteristics of activated carbon are used to remove odor molecules in the gas, thereby purifying the gas. The purified gas is discharged into the storage box 21 by the extraction pump 4. At this time, the valve 23 is opened, and the high-temperature gas in the storage box 21 returns to the aging chamber 1 through the exhaust pipe 22, forming a closed loop circulation.

[0041] Blockage handling and path switching: When the filter hole 331 is blocked by impurities, the resistance of the gas through the main path increases, resulting in a pressure difference before and after the filter plate 33. The pressure difference pushes the filter plate 33 to compress the spring 37 and move it along the guide rod 36 towards the filter screen 35, thus relieving the blockage of the auxiliary pipe 32. The gas is then diverted from the auxiliary pipe 32 to flow directly to the activated carbon filter screen 34, ensuring that the purification process is not interrupted.

[0042] When the filter plate 33 moves, the removal tube 38 corresponding to the filter hole 331 is inserted into the filter hole 331. Through mechanical pushing, the impurities in the hole are removed. The impurities fall to the filter screen 35 and are intercepted and collected. When the impurities are removed and the pressure difference decreases, the spring 37 pushes the filter plate 33 to reset, closes the auxiliary pipe 32, and restores the main path filtration.

[0043] When the gas passes through the auxiliary pipe 32, it pushes the rotating plate 7 to rotate around the rotating shaft 6. The adhesive layer (such as silicone or adhesive) on the surface of the rotating plate 7 captures impurities in the gas, further improving the filtration effect.

[0044] The above description is merely a specific embodiment of this utility model, but the protection scope of this utility model is not limited thereto. Any variations or substitutions that can be easily conceived by those skilled in the art within the technical scope disclosed in this utility model should be included within the protection scope of this utility model. Therefore, the protection scope of this utility model should be determined by the scope of the claims.
