Description

Technical Field

[0001] The present invention relates to the technical field of memory bar testing, and in particular to a computer memory bar aging testing device and method. Background Art

[0002] The aging test of computer memory can be performed in the following ways:Memory stress test: Use some specialized memory testing software, such as Memtest86+, Prime95, etc., to stress test the memory. These software will check the possibility of memory problems by continuously reading and writing memory. During the test, it will monitor whether there are any errors.Memory stability test: Use software such as OCCT, AIDA64, etc. to perform memory stability test. These software will test the memory for a long time to detect whether the memory can run stably for a long time. During the test, continuous reading and writing operations will be performed to verify the stability of the memory.Temperature test: High temperature environment will have a certain impact on the memory module, so the aging test of the memory can be performed by increasing the ambient temperature. Temperature control equipment, such as a thermostat or heater, can be used to increase the ambient temperature to a certain extent. Run the computer under such conditions and perform memory tests to simulate the working state of the memory in a high temperature environment. No matter which test method is used, please make sure to back up important data and follow the instructions for use of the test software. In addition, the aging test will generate additional load on the memory and may generate higher temperatures. Overheating and damage to the hardware should be avoided.

However, during the hot air heating process, it is necessary to ensure the cleanliness of the air and eliminate moisture in the air. If the moisture in the air is high, the moisture in the air will enter the memory stick and the slot, resulting in poor contact between the memory stick and the slot, causing damage to the memory stick, affecting the service life of the memory stick, and causing unnecessary losses.

[0026] Reference Figure 1 , Figure 3 , Figure 5-Figure 7 The zeolite ring 21 is installed on the inner wall of the intake pipe 15 and is used to absorb moisture in the air. The zeolite ring 21 heats the air after absorbing water. The outer wall of the rotating shaft 18 is fixedly connected with a scraper guide plate 26. The top of the scraper guide plate 26 is slidably connected to the bottom of the zeolite ring 21. The bottom of the scraper guide plate 26 is fixedly connected with a conducting pipe 27.

At the same time, the outer wall of the lifting plate 30 is provided with holes for drainage, and the size of the holes is smaller than the hole size of the filter 16.

[0027] In the present invention, when in use, first open the box cover 2 and insert the memory stick into the slot 4. When inserting, the push plate 5 slides downward through the memory stick, and the connecting plate 8 moves downward through the push rod 6. At this time, the connecting plate 8 will drive the piston plate 10 to slide downward along the inner wall of the piston groove 11, so that the temperature sensing airbag 12 is compressed, and at the same time, the test computer 14 is started to perform an aging test on the memory stick using the test software; Then the box cover 2 can be closed, the driving motor 17 can be started to rotate the rotating shaft 18, thereby driving the fan blades 19 to rotate, and the heating network 20 can be started at the same time so that the outside air is sucked into the air inlet pipe 15 through the filter network 16 under the action of the fan blades 19. The air entering the air inlet pipe 15 will pass through the zeolite ring 21, and the zeolite ring 21 will absorb the moisture in the air. At the same time, the zeolite ring 21 will heat up after absorbing the moisture, and the air will be preliminarily heated. Then the air will be heated again through the heating network 20. The heated air will be transmitted to the blowing plate 24 through the connecting pipe 25 and blown out by the blowing plate 24. In this process, due to the rotation of the rotating shaft 18 The rotating plate 22 will be driven to rotate, and then the rotating rod 23 will be driven to rotate, so that the blowing plate 24 will slide along the inner wall of the test box 1 in a circular manner, so that the blowing plate 24 will blow air to the test board 3 and the memory bar for heating, and simulate the ambient temperature to perform an aging test on the memory bar, thereby ensuring the uniformity of the temperature of all memory bars and the test board 3, thereby ensuring the accuracy of the aging test on the memory bar, and preventing moisture in the air from entering the test box 1 and adhering to the connection between the memory bar and the slot 4, causing poor contact between the memory bar and the slot 4, thereby providing good protection for the memory bar and ensuring the service life of the memory bar, thereby ensuring the efficiency and quality of the aging test on the memory bar; At the same time, as the water absorbed by the zeolite ring 21 slowly extends out of the zeolite ring 21 and adheres to the bottom of the zeolite ring 21, due to the rotation of the rotating shaft 18, the scraper guide plate 26 will scrape the water at the bottom of the zeolite ring 21 and guide it into the guide pipe 27, and then into the water storage barrel 28. At the same time, due to the setting of the reciprocating wire 33, the lifting plate 30 will slide up and down cyclically under the action of the limit frame 31. In the process of the lifting plate 30 sliding up and down, the connecting ring 29 will slide up and down along the inner wall of the water storage barrel 28. When the lifting plate 30 slides upward, the connecting ring 29 will slide upward along the water storage barrel 28, and the water in the water storage barrel 28 will be squeezed into the lifting plate 30 through the connecting ring 29. The lifting plate 30 sprays the filter 16 to flush the filter 16, and at the same time, the cleaning frame 32 driven by the rotating shaft 18 fully cleans the filter 16, thereby improving the cleanliness of the filter 16 and preventing the filter 16 from being blocked and affecting the air intake efficiency. When the memory stick is subjected to a temperature aging test, when the temperature of the memory stick and the slot 4 is higher than a threshold value, the temperature-sensing airbag 12 will absorb the temperature of the memory stick and the slot 4, causing the temperature-sensing airbag 12 to expand, pushing the piston plate 10 to slide upward, and then pushing the push plate 5 upward through the connecting plate 8 via the push rod 6, pushing the memory stick out of the slot 4, and cleaning and cooling the slot 4, thereby providing good protection for the memory stick and preventing the memory stick from being burned or the slot 4 due to a high temperature during the temperature aging test, thereby causing unnecessary trouble and loss.

[0028] like Figure 1 , Figure 7 , Figure 8 A sliding rod 34 is slidably connected to the side wall of the intake pipe 15. One end of the sliding rod 34 extending to the inner wall of the intake pipe 15 is fixedly connected to a semicircular ball 35. A return spring 36 is sleeved on the sliding rod 34, and the return spring 36 is located between the inner wall of the intake pipe 15 and the semicircular ball 35.

[0029] The outer wall of the intake pipe 15 is fixedly connected to a piston assembly 37, and the sliding rod 34 extends to one end of the outer wall of the intake pipe 15 and is fixedly connected to a piston plate in the piston assembly 37. An air intake port 38 is provided on the side wall of the intake pipe 15, and the air intake port 38 is located below the zeolite ring 21. An air intake pipe 39 is connected between the piston cylinder on the piston assembly 37 and the air intake port 38.

[0030] An expansion airbag 40 is fixedly connected to the outer wall of the air intake pipe 15, a first movable hose 41 is connected between the expansion airbag 40 and the piston cylinder on the piston assembly 37, a nozzle 44 is provided on the inner wall of the test box 1, a second movable hose 42 is connected between the nozzle 44 and the expansion airbag 40, and a pressure relief valve 43 is installed on the second movable hose 42.

[0031] One-way valves are installed on both the intake pipe 39 and the first movable hose 41; the one-way valve on the intake pipe 39 allows gas to enter the piston cylinder of the piston assembly 37 only through the intake pipe 39; the one-way valve on the first movable hose 41 allows gas to enter the first movable hose 41 only through the piston cylinder of the piston assembly 37.

[0032] When the scraper plate 26 rotates periodically to scrape off the moisture attached to the zeolite ring 21, when it rotates to the hemisphere 35, the push sliding rod 34 moves, thereby driving the piston plate in the piston assembly 37 to move. Under the action of the return spring 36, it moves back and forth, and the air at the bottom of the zeolite ring 21 is sucked into the expansion airbag 40 for storage through the suction pipe 39 and the first movable hose 41. Since the air humidity at the bottom of the zeolite ring 21 is relatively high, the air sucked in is also high-humidity gas.

[0033] When the pressure in the inflatable airbag 40 reaches the value set by the pressure relief valve 43, the pressure relief valve 43 automatically opens, and a high-humidity airflow is ejected through the nozzle 44 toward the computer memory stick, cooperating with the gas heated by the heating network 20 to test the performance of the memory stick in a high temperature and high humidity environment.

[0034] That is to say, the rotating scraper plate 26 not only has the function of scraping off the moisture of the zeolite ring 21, but also cooperates with the piston assembly 37 to test the performance under high temperature and high humidity environment.

[0035] Furthermore, the absorption of moisture in the air not only improves the heating effect of the heating network 20, but also extracts moisture from the air, thereby preparing for the subsequent operation of the piston assembly 37 to test the performance in a high temperature and high humidity environment.

[0036] At the same time, Figure 1 A dust storage tank 45 is provided in the test box 1, and fine dust is contained in the dust storage tank 45. A filling port is provided on the dust storage tank 45 for easy filling of dust. The dust storage tank 45 is located at the bottom of the second movable hose 42, and the top of the dust storage tank 45 is connected to the second movable hose 42.

[0037] When the high-humidity airflow passes through the second movable hose 42, since the second movable hose 42 is connected to the top of the dust storage tank 45, in this process, since the gas flow rate in the second movable hose 42 is much higher than the gas in the dust storage tank 45, in fact, the gas in the dust storage tank 45 is in a stationary state. At this time, the flow rate in the second movable hose 42 is fast, and the pressure will become smaller, forming a negative pressure. Therefore, part of the dust in the dust storage tank 45 will enter the second movable hose 42, and then be ejected from the nozzle 44 along with the airflow, simulating the performance of the memory stick in a harsh environment.

[0038] Under the action of the pressure relief valve 43, the second movable hose 42 periodically transports gas. When no gas is transported in the second movable hose 42, the pressure between the second movable hose 42 and the dust storage tank 45 will be the same. At this time, the dust in the dust storage tank 45 will be in a static state. Therefore, the dust storage tank 45 is arranged below the second movable hose 42. When the nozzle 44 does not spray, the dust in the dust storage tank 45 will not enter the second movable hose 42, thereby ensuring that the dust is as dry as possible.

[0039] like Figure 9-13 A disturbance shaft 48 is rotatably arranged on the inner wall of the test box 1 , a guide plate 46 is fixedly connected to the disturbance shaft 48 , and a disturbance groove 47 is arranged at the top and the bottom of the guide plate 46 .

[0040] A guide plate 46 is provided at the air outlet of each nozzle 44 , and when the guide plate 46 is in a horizontal state, it is flush with the center of the nozzle 44 .

[0041] One end of the disturbance shaft 48 is fixedly connected to an adjustment cylinder 49, and electromagnetic coils 50 are provided on both sides of the adjustment cylinder 49. An adjustment ball 51 is also provided in the adjustment cylinder 49. Counterweight sleeves 52 are slid inside both ends of the adjustment cylinder 49, and an adjustment spring 53 is connected between the counterweight sleeve 52 and the adjustment cylinder 49. A second adjustment electrode contact 55 is provided on one side of the counterweight sleeve 52. The inner walls at both ends of the adjustment cylinder 49 are also correspondingly provided with first adjustment electrode contacts 54, and the first adjustment electrode contacts 54 can contact the second adjustment electrode contacts 55 on the same side.

[0042] The adjustment ball 51 is a metal ball.

[0043] The bottom of the expansion airbag 40 is connected to a control cylinder 56 , in which a first control electrode contact piece 57 is slidably connected. A second control electrode contact piece 59 is provided at the bottom of the control cylinder 56 , and a control tension spring 58 is connected between the first control electrode contact piece 57 and the top of the control cylinder 56 .

[0044] When the pressure in the inflatable airbag 40 reaches a certain level, the nozzle 44 sprays air, and the airflow blows the corresponding guide plate 46. At the same time, under the action of the pressure in the inflatable airbag 40, the air pressure pushes the first control electrode contact 57 downward, and the first control electrode contact 57 contacts the second control electrode contact 59, and the control circuit is turned on. At this time, Fig.11 , the electromagnetic coil 50 on the left side of the regulating cylinder 49 is energized to generate electromagnetic ejection. Under the action of the electromagnetic ejection force, the regulating ball 51 is ejected to the right and ejected to the right side of the regulating cylinder 49. At this time, under the action of the gravity of the regulating ball 51, the right side of the regulating cylinder 49 tilts downward, and the guide plate 46 rotates, driving the side of the guide plate 46 close to the nozzle 44 to move upward. At this time, under the action of the guide plate 46, most of the gas ejected from the nozzle 44 flows downward; At the same time, when the adjusting ball 51 is ejected to the right side of the adjusting cylinder 49, squeezing the counterweight sleeve 52 on the right side, the first adjusting electrode contact piece 54 on the same side contacts with the second adjusting electrode contact piece 55 on the same side, and the electromagnetic control circuit is turned on, so that the electromagnetic coil 50 on the left side is in an open circuit state. Similarly, when the adjusting ball 51 is on the left side, the electromagnetic coil 50 on the right side is in an open circuit state. That is to say, due to the existence of the adjusting ball 51, each time the first control electrode contact piece 57 contacts with the second control electrode contact piece 59, only one side of the electromagnetic coil 50 on both sides of the adjusting cylinder 49 will be energized, and the electromagnetic coil 50 on the same side as the adjusting ball 51 will be energized. That is to say, the electromagnetic coils 50 on both sides will be alternately energized under the action of the adjusting ball 51 to generate electromagnetic force; that is to say, when the inflatable airbag 40 makes the nozzle 44 spray next time, the adjusting ball 51 will be ejected to the left side of the adjusting cylinder 49 again. At this time, Fig.11 The left side of the regulating cylinder 49 tilts downward, thereby causing the guide plate 46 to move downward on the side close to the nozzle 44, and most of the gas ejected from the nozzle 44 flows upward.

[0045] Furthermore, each time the inflated airbag 40 makes the nozzle 44 spray air, the airflow sometimes flows upward and sometimes flows downward under the action of the guide plate 46, so a turbulent flow is formed in the test box 1. Under the action of the turbulent flow, the sprayed hot air flow, humid air flow, and air flow containing dust will be randomly disturbed with the air flow, and act on the computer memory stick from all aspects, thereby avoiding acting in the same direction for a long time and ensuring a comprehensive test.

[0046] That is to say, by expanding the gas in the airbag 40, the direction of the guide plate 46 can be controlled synchronously through the adjusting tube 49, thereby changing the direction of the airflow; and the adjusting ball 51 not only controls the direction in which the adjusting tube 49 tilts, but also automatically cuts off the power to the electromagnetic coil 50 on the other side, thereby preventing the electromagnetic coils 50 on both sides from being energized at the same time, thereby creating resistance to the ejection of the adjusting ball 51.

[0047] like Fig.10 The shapes of the spoiler grooves 47 on each guide plate 46 are different. Some are inclined to the left, some are inclined to the right, some are larger at the top and smaller at the bottom and inclined to one side, etc., thereby ensuring that when the airflow passes through the surface of the guide plate 46, it will be blown in different directions under the action of the spoiler grooves 47 of different shapes, further achieving the spoiler effect.

[0048] Under the action of the control tension spring 58, the first control electrode contact piece 57 and the second control electrode contact piece 59 are in a separated state. They will only contact when the pressure reaches a set value, and will separate again when the pressure drops.

[0049] Reference Figure 1-Figure 8A computer memory bar aging test method comprises the following steps: Step 1: Open the box cover 2 and insert the memory stick into the slot 4; When in use, first open the box cover 2 and insert the memory stick into the slot 4. When inserting, the push plate 5 slides downward through the memory stick, and the connecting plate 8 moves downward through the push rod 6. At this time, the connecting plate 8 will drive the piston plate 10 to slide downward along the inner wall of the piston groove 11, so that the temperature sensing airbag 12 is compressed, and at the same time, the test computer 14 is started to perform an aging test on the memory stick using the test software; Step 2: Start the heating net 20 and the driving motor 17 to introduce hot air into the test box 1 to heat the memory stick; The box cover 2 is closed, and the driving motor 17 is started to rotate the rotating shaft 18, thereby driving the fan blades 19 to rotate. At the same time, the heating network 20 is started so that the outside air is sucked into the air inlet pipe 15 through the filter network 16 under the action of the fan blades 19. The air entering the air inlet pipe 15 will pass through the zeolite ring 21, and the zeolite ring 21 will absorb the moisture in the air. At the same time, the zeolite ring 21 will heat up after absorbing the moisture, and the air will be preliminarily heated. Then the air will be heated again through the heating network 20. The heated air will be transmitted to the blowing plate 24 through the connecting pipe 25 and blown out by the blowing plate 24. In this process, the rotation of the rotating shaft 18 will The rotating plate 22 is driven to rotate, and then the rotating rod 23 is driven to rotate, so that the blowing plate 24 slides cyclically along the inner wall of the test box 1, so that the blowing plate 24 blows air to the test board 3 and the memory bar for heating, and simulates the ambient temperature to perform an aging test on the memory bar, thereby ensuring the uniformity of the temperature of all memory bars and the test board 3, thereby ensuring the accuracy of the aging test on the memory bar, and preventing moisture in the air from entering the test box 1 and adhering to the connection between the memory bar and the slot 4, causing the memory bar and the slot 4 to have a poor contact, thereby providing good protection for the memory bar and ensuring the service life of the memory bar, thereby ensuring the efficiency and quality of the aging test on the memory bar; At the same time, as the water absorbed by the zeolite ring 21 slowly extends out of the zeolite ring 21 and adheres to the bottom of the zeolite ring 21, due to the rotation of the rotating shaft 18, the scraper guide plate 26 will scrape the water at the bottom of the zeolite ring 21 and guide it into the guide pipe 27, and then into the water storage barrel 28. At the same time, due to the setting of the reciprocating wire 33, the lifting plate 30 will slide up and down cyclically under the action of the limit frame 31. In the process of the lifting plate 30 sliding up and down, the connecting ring 29 will slide up and down along the inner wall of the water storage barrel 28. When the lifting plate 30 slides upward, the connecting ring 29 will slide upward along the water storage barrel 28, and the water in the water storage barrel 28 will be squeezed into the lifting plate 30 through the connecting ring 29. The lifting plate 30 sprays the filter 16 to flush the filter 16, and at the same time, the cleaning frame 32 driven by the rotating shaft 18 fully cleans the filter 16, thereby improving the cleanliness of the filter 16 and preventing the filter 16 from being blocked and affecting the air intake efficiency. When the temperature of the memory stick is subjected to a temperature aging test, when the temperature of the memory stick and the slot 4 is higher than a threshold value, the temperature-sensing airbag 12 will absorb the temperature of the memory stick and the slot 4, causing the temperature-sensing airbag 12 to expand, pushing the piston plate 10 to slide upward, and then pushing the push plate 5 upward through the connecting plate 8 via the push rod 6, pushing the memory stick out of the slot 4, and cleaning and cooling the slot 4, thereby providing good protection for the memory stick, and preventing the memory stick from being burned due to a high temperature during the temperature aging test, thereby causing unnecessary trouble and loss; Step 3: During the heating process, the performance of the memory stick is tested by using the test computer 14; Step 4: After the test is completed, open the box cover 2 and take out the memory stick.
