Description

Technical Field

[0001] The present application relates to the technical field of ultra-low temperature glass plate detection, and in particular to a multifunctional ultra-low temperature glass plate performance detection device. Background Art

[0002] Ultra-low temperature glass plates are generally used as observation windows, and are mostly used in aerospace, low-temperature storage and refrigeration equipment and other fields. For example, when quartz glass is used, the ultra-low temperature glass plates will be subjected to hot and cold cycles. For example, when the ultra-low temperature glass plates are used as spacecraft observation windows, they will experience temperature changes from the earth's shadow area to the direct sunlight area. The temperature experienced by the ultra-low temperature glass plates will gradually change. Therefore, the hot and cold cycle test of the ultra-low temperature glass plates is of great significance. It can simulate actual use conditions, evaluate the impact of temperature changes on performance, and ensure the safety and reliability of the product. The current hot and cold cycle test equipment has two ways to achieve hot and cold cycles. The first is to switch the product between two chambers with different temperatures. The temperature experienced by the product changes drastically. The second is The product is placed in a chamber, and then refrigeration and heating equipment are used to gradually change the temperature in the chamber, so that the temperature that the product contacts gradually changes alternately. Because the temperature experienced by the ultra-low temperature glass plate when used as a spacecraft observation window is gradually alternating, it is more appropriate to use the second method when conducting hot and cold cycle experiments on the ultra-low temperature glass plate. However, the second method uses a direct offset method to convert hot and cold when implementing the hot and cold cycle. For example, when changing from low temperature to high temperature, heating equipment will be used to heat the temperature in the test chamber to high temperature.

DETAILED DESCRIPTION

[0024] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention.

Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0025] Example 1

[0026] A multifunctional ultra-low temperature glass plate performance detection device, such as Figure 1-Figure 4 As shown, it includes a base frame 1, a detection chamber 2, a through pipe 1 3 and a through pipe 2 4; the detection chamber 2 is fixedly connected to the base frame 1, and a temperature sensor is arranged on the detection chamber 2; three placement slots 201 are opened on the detection chamber 2; three through holes 202 are opened on the detection chamber 2; each through hole 202 is connected to a corresponding placement slot 201; a plurality of through pipes 1 3 are equidistantly penetrated on the upper part of the detection chamber 2; a plurality of through pipes 2 4 are equidistantly penetrated on the lower part of the detection chamber 2;

[0027] It also includes a cylinder 1 5, a pressure plate 6, a camera 7, a cylinder 2 8, a partition 1 9, and a partition 2 10; two cylinders 1 5 are fixedly connected to the base frame 1; the telescopic ends of all cylinders 1 5 are fixedly connected to the pressure plate 6; three limit grooves 601 are provided on the pressure plate 6; three observation holes 602 are provided on the detection chamber 2; each observation hole 602 is respectively connected to the corresponding limit groove 601; three cameras 7 are fixedly connected to the pressure plate 6, and the cameras 7 are directly opposite to the observation holes 602; two cylinders 2 8 are fixedly connected to the base frame 1; the telescopic ends of all cylinders 2 8 are fixedly connected to the partition 1 9; the partition 1 9 is located between the through pipe 1 3 and the through pipe 2 4; the partition 1 9 is slidably connected to the detection chamber 2; the right end of the partition 1 9 is connected to the partition 2 10; the partition 2 10 is located in the detection chamber 2, and the partition 2 10 is in contact with the inner wall of the detection chamber 2.

[0028] In order to facilitate observation of the internal conditions of the ultra-low temperature glass plate 11 , an illumination lamp is provided on the side of each camera 7 .

[0029] In order to facilitate the placement of the ultra-low temperature glass plate 11, the edge of the placement groove 201 is beveled.

[0030] In order to facilitate the installation on the ultra-low temperature glass plate 11, the edge of the limiting groove 601 is beveled.

[0031] It also includes a cylinder three 12 and a baffle 13; three cylinders three 12 are fixedly connected to the base frame 1; each cylinder three 12 is fixedly connected to a baffle 13 at its telescopic end; each baffle 13 is slidably connected to the detection chamber 2.

[0032] The first step: connect the through pipe 1 3 to the external heating system, and connect the through pipe 2 4 to the external refrigeration system; the external loading robot places the ultra-low temperature glass plate 11 on the placement groove 201, and the ultra-low temperature glass plate 11 contacts the internal environment of the detection chamber 2 through the through hole 202, and controls the external refrigeration system to pass liquid nitrogen cold air into the detection chamber 2 through the through pipe 2 4, so that the ambient temperature in the detection chamber 2 becomes the lowest tolerance temperature of the ultra-low temperature glass plate 11, such as about -196°C. The ambient temperature in the detection chamber 2 is monitored by the temperature sensor arranged on the upper side of the detection chamber 2, and then the cylinder 1 5 is controlled to drive the pressing plate 6 and the camera 7 to move downward, so that the upper part of the ultra-low temperature glass plate 11 is sleeved in the limiting groove 601 on the pressing plate 6, so that the ultra-low temperature glass plate 11 is fixed, and at the same time, the camera 7 is located directly above the ultra-low temperature glass plate 11 to observe the state of the ultra-low temperature glass plate 11.

[0033] Step 2: Let it stand for a while, so that the lower side of the ultra-low temperature glass plate 11 can stand in this low temperature environment for a certain period of time; then control the cylinder 28 to drive the partition 19 and the partition 210 to move to the right, and move to the right of the partition 210 to be located at the through hole 202. After moving, the lower side of the ultra-low temperature glass plate 11 contacts the space formed by the detection chamber 2, the upper side of the partition 19 and the left side of the partition 210. During the movement, the external refrigeration system is controlled to suck the cold air originally located in this space back into the refrigeration system through the through pipe 24. The pushing effect of the partition 210 can assist the cold air to return to the refrigeration system. During the movement, the external heating system is controlled to move to the detection chamber 2 and the upper side of the partition 9 through the through pipe 3. High-temperature hot air is injected into the space formed by the side and the left side of the partition 2 10, so that the ambient temperature in the space formed by the detection chamber 2, the partition 1 9 and the partition 2 10 gradually rises to the highest tolerance temperature of the ultra-low temperature glass plate 11, such as about 1000°C, so that the lower side of the ultra-low temperature glass plate 11 is allowed to stand for a certain period of time in this high-temperature environment; through the separation effect of the upper side of the partition 1 9 and the partition 2 10, the space where the lower side of the ultra-low temperature glass plate 11 is located becomes smaller, and the smaller the space, the faster the temperature rises, thus accelerating the temperature rise speed of the environment where the lower side of the ultra-low temperature glass plate 11 is located; then, the control cylinder 2 8 drives the partition 1 9 and the partition 2 10 to move to the left and reset, so that the partition 2 10 is in the position of On the left side of the through hole 202, during the movement, the external heating system is controlled to draw the hot air in the space composed of the detection chamber 2, the upper side of the partition 1 9 and the left side of the partition 2 10 back into the heating system through the through pipe 1 3. The pushing effect of the partition 2 10 can assist the hot air to return to the heating system. At the same time, the external refrigeration system passes the cold air pushed back previously into the detection chamber 2 through the through pipe 2 4, so that the environment contacted by the ultra-low temperature glass is changed to the lowest tolerance temperature of the ultra-low temperature glass plate 11 again, so that the lower side of the ultra-low temperature glass plate 11 is allowed to stand for a certain period of time in this low temperature environment again; repeat the above actions, so that the ultra-low temperature glass plate 11 undergoes multiple hot and cold cycle tests. During the hot and cold cycle test process, In the process, the state of the ultra-low temperature glass plate 11 is observed by the camera 7 to see whether there are cracks, so as to evaluate the state of the ultra-low temperature glass plate 11 under multiple temperature changes to ensure its reliability and safety in long-term use. If there are cracks, it means that the performance of the ultra-low temperature glass plate 11 is unqualified, and if there are no cracks, it is qualified; when the ambient temperature contacted by the ultra-low temperature glass plate 11 changes from low temperature to high temperature, the cold air on the lower side of the ultra-low temperature glass plate 11 is first pushed back into the refrigeration system, and then hot air is passed to heat the lower side of the ultra-low temperature glass plate 11. In this way, the introduced hot air will not be cooled by the original cold air, so that the lower side of the ultra-low temperature glass plate 11 can be quickly heated, reducing time consumption;When the ambient temperature of the ultra-low temperature glass plate 11 changes from high temperature to low temperature, the hot air on the lower side of the ultra-low temperature glass plate 11 is first pushed back into the heating system, and then the cold air is passed to cool the lower side of the ultra-low temperature glass plate 11. In this way, the cold air passed in will not be heated by the original hot air, so that the lower side of the ultra-low temperature glass plate 11 can be cooled quickly, reducing the time consumption; at the same time, by pushing the hot air and the cold air back to the corresponding heating system and the refrigeration system for reuse during the hot and cold cycle test, it is also beneficial to save energy. ;

[0034] Step 3: Control cylinder 2 8 to drive partition 1 9 and partition 2 10 to move to the left and reset, so that partition 2 10 is located on the left side of the through hole 202, and then control cylinder 1 5 to drive the pressing plate 6 and the camera 7 to move up, so that the upper part of the ultra-low temperature glass plate 11 is separated from the limiting groove 601 on the pressing plate 6, and then control cylinder 3 12 to drive baffle 13 to move to the left, so that the baffle 13 is located below the ultra-low temperature glass plate 11, and the through hole 202 is blocked by the baffle 13 to prevent the cold air or hot air in the detection chamber 2 from being lost, and then the external loading robot can remove the ultra-low temperature glass plate 11; when a new batch of ultra-low temperature glass plates 11 are subsequently tested, the ultra-low temperature glass plates 11 are placed in the placement groove 201, and then the cylinder 3 12 is controlled to drive the baffle 13 to move to the right and reset.

[0035] Example 2

[0036] On the basis of Example 1, Figure 4-Figure 5 As shown, it also includes an airbag 21, a scraper 22, a straight spring 23, a mounting plate 1 24, a cylinder 4 25 and a mounting plate 2 26; three airbags 21 are arranged in the partition 2 10; three scrapers 22 are slidably connected in the partition 2 10; the upper side of each airbag 21 is respectively in contact with a scraper 22; three mounting plates 1 24 are slidably connected in the partition 2 10; each mounting plate 1 24 is in contact with an airbag 21; two straight springs 23 are respectively fixed to each mounting plate 1 24; all the straight springs 23 are fixed to the partition 2 10; three cylinders 4 25 are fixed to the base frame 1; all the telescopic ends of the cylinders 4 25 are slidably connected to the detection chamber 2; each telescopic end of the cylinder 4 25 is respectively fixed to a mounting plate 2 26; each mounting plate 2 26 is directly opposite to the corresponding mounting plate 1 24.

[0037] In order to prevent the ultra-low temperature glass plate 11 from being scratched, the upper portion of the scraper 22 is configured to be arc-shaped.

[0038] In the second step of Example 1: observe the condition of the ultra-low temperature glass plate 11 through the camera 7 to see if there are any cracks. During the test, the ultra-low temperature glass plate 11 may produce extremely fine cracks, and some may not even produce cracks, but have accumulated relatively high internal stress and are about to produce cracks. The above situations are not convenient for observation by the camera 7; therefore, when the control cylinder 2 8 drives the partition 1 9 and the partition 2 10 to move to perform the secondary temperature switching process, take the conversion from low temperature to high temperature as an example, that is, the control cylinder 2 8 drives the partition 1 9 and the partition 2 10 to move to the right, when the partition 2 10 moves to the inner left side of the through hole 202, it stops first, and then the control cylinder 4 25 drives the mounting plate 2 26 to move to the left, so that the mounting plate 2 26 contacts the mounting plate 1 24, and then drives the mounting plate 1 24 to move to the left to compress the straight spring 23 and the airbag 21, and the airbag 21 is set to tend to When the airbag 21 is deformed upward and compressed, it bulges upward to lift the scraper 22, so that the scraper 22 moves up and contacts the ultra-low temperature glass plate 11. The scraper 22 applies a certain pressure to the ultra-low temperature glass plate 11, and then controls the partition 2 10 to move to the right. During the movement, the control cylinder 4 25 drives the mounting plate 2 26 to move to the right synchronously, so that the scraper 22 is always in contact with the ultra-low temperature glass plate 11, that is, the scraper 22 slides on the lower side of the ultra-low temperature glass plate 11. The friction between the scraper 22 and the ultra-low temperature glass plate 11 will promote the generation of cracks and expand the small cracks, thereby facilitating the observation of the camera 7; when the partition 2 10 moves to the inner right side of the through hole 202, the control cylinder 4 25 drives the mounting plate 2 26 to move to the right, so that the mounting plate 26 is separated from the mounting plate 1 24, thereby separating the scraper 22 from the ultra-low temperature glass plate 11.

[0039] In addition, in the process of pushing the hot air and cold air for the test back and forth to the heating system and the refrigeration system through the partition 2 10, the upper side of the partition 2 10 is always in contact with the upper side of the detection chamber 2, and there is a certain gap between the lower side of the ultra-low temperature glass plate 11 and the upper side of the detection chamber 2. The partition 2 10 cannot push out the hot air or cold air in the space formed by the lower side of the ultra-low temperature glass plate 11 and the through hole 202, resulting in residual hot air or cold air and the test cold air or hot air being mixed, resulting in a slower temperature change rate; therefore, when the scraper 22 slides on the lower side of the ultra-low temperature glass plate 11, the scraper 22 can also assist in pushing out the hot air or cold air in the space formed by the lower side of the ultra-low temperature glass plate 11 and the through hole 202, effectively reducing the mixing of residual hot air or cold air and the test cold air or hot air, resulting in a slower temperature change rate.

[0040] Example 3

[0041] On the basis of Example 2, Figure 6 As shown, in order to facilitate the cleaning of debris, the lower bottom plate of the detection chamber 2 is detachable.

[0042] It also includes a spring telescopic rod 41 and a convex rod 42; a plurality of spring telescopic rods 41 are fixedly connected at equal distances in the partition 1 9; the telescopic ends of all spring telescopic rods 41 are fixedly connected to the partition 2 10; a plurality of convex rods 42 are fixedly connected to the partition 2 10; a plurality of grooves 203 are opened at equal distances on the left side of the detection chamber 2; each convex rod 42 is directly opposite to the corresponding groove 203.

[0043] In order to facilitate the insertion of the protruding rod 42 into the groove 203, the left end of the protruding rod 42 is configured to be arc-shaped.

[0044] Hot and cold cycles will cause fatigue accumulation of ultra-low temperature glass, resulting in a decrease in the strength of ultra-low temperature glass. The impact test after hot and cold cycles can be used to evaluate the strength of ultra-low temperature glass after hot and cold cycles. Therefore, after the ultra-low temperature glass has undergone multiple hot and cold cycles, the control cylinder 28 drives the partition 1 9 and the partition 2 10 to move until the partition 2 10 is directly below the ultra-low temperature glass, and then the control cylinder 4 25 quickly drives the mounting plate 2 26 to move to the left, so that the mounting plate 26 collides with the mounting plate 1 24, and then drives the mounting plate 1 24 to move to the left to compress the straight spring 23 and the airbag 21. The airbag 21 is set to tend to deform upward. After the airbag 21 is compressed, it bulges upward to lift the scraper 22, so that the scraper 22 moves up and hits the ultra-low temperature glass. Plate 11, after reciprocating and hitting the ultra-low temperature glass plate 11 for many times, stop, and observe the state of the ultra-low temperature glass plate 11 through the camera 7. If the ultra-low temperature glass plate 11 cracks after the impact, it means that the strength is unqualified, otherwise it is qualified; after the ultra-low temperature glass is hit, there will be very small cracks, some even have no cracks, but have accumulated high internal stress, and are about to crack. The above situations are not convenient for the camera 7 to observe; at this time, the action in Example 2 can be repeated, and the scraper 22 is allowed to slide on the lower side of the ultra-low temperature glass plate 11 while applying a certain pressure to the ultra-low temperature glass plate 11. The scraper 22 and the ultra-low temperature glass plate 11 generate friction, which promotes the generation of cracks and causes the small cracks to expand, thereby facilitating the observation of the camera 7.

[0045] After the glass plate cracks, small debris may be generated, and the debris will fall on the bottom of the detection chamber 2 and the partition 9. The debris needs to be cleaned up later to avoid debris accumulation and affect subsequent tests. For the debris on the partition 9, the control cylinder 28 drives the partition 9, the partition 10, the spring telescopic rod 41, and the protruding rod 42 to move to the left, so that the protruding rod 42 is against the groove 203, and then the control cylinder 28 continues to drive the partition 9 and the spring telescopic rod 41 to move. Due to the resistance of the detection chamber 2, the protruding rod 42 and the partition 10 no longer move to the left, so that the partition 9 and the partition 10 move relative to each other, and the spring telescopic rod 41 is stretched. When the right side of the partition 9 is flush with the left side of the detection chamber 2, the debris on the partition 9 will lose the support of the partition 9 and fall to the bottom of the detection chamber 2. For the debris at the bottom of the detection chamber 2, the bottom of the detection chamber 2 can be manually disassembled for cleaning.

[0046] Finally, it should be noted that the above is only a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, it is still possible for those skilled in the art to modify the technical solutions described in the aforementioned embodiments or to make equivalent substitutions for some of the technical features therein.
