Detailed implementation manners

[0043] To make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention. Apparently, the described embodiments are some, but not all, of the embodiments of the present invention. Usually, the components of the embodiments of the present invention described and illustrated herein can be arranged and designed in various different configurations.

[0044] Accordingly, the following detailed description of the embodiments of the present invention provided in the accompanying drawings is not intended to limit the scope of the claimed invention, but merely represents selected embodiments of the present invention. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts fall within the scope of protection of the present invention.

[0045] It should be noted that like reference numerals and letters denote like items in the following drawings. Therefore, once an item is defined in one drawing, it does not require further definition and explanation in subsequent drawings.

[0046] The terms "first", "second", "third", etc. are only used for descriptive distinction and should not be construed as indicating or implying relative importance.

[0047] In addition, terms such as "parallel" and "perpendicular" do not require the components to be absolutely parallel or perpendicular, but may be slightly inclined. For example, "parallel" only means that its direction is more parallel relative to "perpendicular", and does not mean that the structure must be completely parallel, but may be slightly inclined.

[0048] In the description of the present invention, it should also be noted that unless otherwise clearly specified and limited, the terms "arranged", "installed", and "connected" should be understood in a broad sense. For example, it may be a fixed connection, a detachable connection, or an integral connection; it may be directly connected, or indirectly connected through an intermediate medium, and may be the communication inside two components. For those of ordinary skill in the art, the specific meanings of the above terms in the present invention can be understood according to specific situations.

[0049] To overcome the deficiencies in the prior art, please refer to Figures 1-3 , this embodiment provides a device for detecting the structural strength of a microcrystalline glass panel. The device for detecting the structural strength of a microcrystalline glass panel includes: a driving mechanism 100, an impact head 200, a test bench 300, a first container 400, and a second container 500.

[0050] The test bench 300 is used for installing the microcrystalline glass panel 2000 to be tested.

[0051] The driving mechanism 100 is in transmission cooperation with the impact head 200 so that the impact head 200 can periodically impact the microcrystalline glass panel 2000 to be tested installed on the test bench 300, thereby detecting the structural strength of the microcrystalline glass panel 2000 to be tested by using the impact head 200.

[0052] The impact head 200 has an internal flow channel 210. The first container 400 is used for containing a hot fluid medium, and the second container 500 is used for containing a cold fluid medium. The hot fluid medium and the cold fluid medium can be selected as gas media or can also use liquid media.

[0053] Both the first container 400 and the second container 500 are communicated with the internal flow channel 210 through a switch control mechanism 600.

[0054] The switch control mechanism 600 is used to alternately communicate one of the first container 400 and the second container 500 with the internal flow channel 210.

[0055] When the switch control mechanism 600 communicates the first container 400 with the internal flow channel 210, the hot fluid medium in the first container 400 enters the internal flow channel 210, and the hot fluid medium heats the impact head 200, so that the impact head 200 has a higher temperature when hitting the microcrystalline glass panel 2000 to be tested.

[0056] When the switch control mechanism 600 communicates the second container 500 with the internal flow channel 210, the cold fluid medium in the second container 500 enters the internal flow channel 210, and the cold fluid medium cools the impact head 200, so that the impact head 200 has a lower temperature when hitting the microcrystalline glass panel 2000 to be tested.

[0057] Through the above design, the temperature of the impact head 200 can be adjusted. In this way, it is possible to simulate the impact on the microcrystalline glass panel 2000 to be tested by using a "hotter object" and the impact on the microcrystalline glass panel 2000 to be tested by using a "colder object", so as to simulate the scenarios in which the microcrystalline glass panel 2000 to be tested is impacted by high-temperature objects and low-temperature objects during the actual application process, which can more truly reflect the actual structural strength of the microcrystalline glass panel 2000 when in actual use.

[0058] Generally speaking, the microcrystalline glass panel structural strength detection device provided in this embodiment can perform targeted testing on the structural strength of the microcrystalline glass panel according to the application scenarios in the actual use process. The test process has a higher degree of fit with the actual application scenarios, which helps to improve the credibility of the test results and makes the test results more valuable for reference.

[0059] It can be understood that the impact head 200 is also provided with a discharge port 211 for discharging the medium in the internal flow channel 210. The medium that has undergone heat exchange with the impact head 200 can be recycled through the discharge port 211, or the medium that has undergone heat exchange with the impact head 200 can be directly discarded through the discharge port 211, and specific selection can be made flexibly according to actual needs.

[0080] During the process of the first cylinder body 710 and the second cylinder body 810 transporting the medium, the temporary storage mechanism 900 is used to temporarily store the transported medium, facilitating the switch control mechanism 600 to separately transport the medium in the two temporary storage mechanisms 900 to the impact head 200 as needed, so as to improve flexibility and reduce the requirements for the working coordination of the first cylinder body 710 and the second cylinder body 810.

[0081] In addition, when the switch control mechanism 600 connects the temporary storage mechanism 900 and the impact head 200, the temporary storage mechanism 900 can use the elastic force provided by the first elastic member 930 to send the medium therein into the impact head 200, and the force of the temporary storage mechanism 900 to transport the medium can be adjusted by adjusting the elastic force of the first elastic member 930, which is simple and convenient.

[0082] In this embodiment, please combine Figure 8 The impact head 200 is provided with a matching blind hole 220 , and the end of the drive shaft 140 is fitted into the matching blind hole 220 .

[0083] The drive shaft 140 is rotatably fitted in the matching blind hole 220 along the circumferential direction of the drive shaft 140. The drive shaft 140 is slidably fitted in the matching blind hole 220 along the axial direction of the drive shaft 140.

[0084] The impact head 200 is restricted from rotating by the limiting frame 230 , that is, the impact head 200 cannot rotate relative to the limiting frame 230 . The impact head 200 is slidably engaged with the limiting frame 230 along the axial direction of the driving shaft 140 .

[0085] The driving shaft 140 is rotatably sleeved with a matching ring 141 . A second elastic member 142 abuts against the matching ring 141 and the impact head 200 . The second elastic member 142 is used to push the impact head 200 toward the side where the test bench 300 is located.

[0086] The internal flow channel 210 is located on the side of the matching blind hole 220 away from the driver 111 and is spaced apart from the matching blind hole 220 . The internal flow channel 210 is located at one end of the impact head 200 close to the test bench 300 , and is arranged close to the end face of the impact head 200 .

[0087] A mounting hole is provided on the end face of the impact head 200 away from the driver 111 . The mounting hole extends along the axial direction of the drive shaft 140 , penetrates into the internal flow channel 210 and further penetrates into the inner wall of the end of the matching blind hole 220 away from the driver 111 .

[0088] An impact terminal 240 is provided in the mounting hole. The diameter of the impact terminal 240 is adapted to the aperture of the mounting hole. The impact terminal 240 slides into the mounting hole of the impact head 200, and the outer wall of the impact terminal 240 fits with the hole wall of the mounting hole.

[0089] One end of the impact terminal 240 extends into the mating blind hole 220, and the other end of the impact terminal 240 extends outside the impact head 200. There is a sliding seal between the impact terminal 240 and the hole wall of the mounting hole of the impact head 200. That is to say, the medium in the internal flow channel 210 will not enter the mating blind hole 220 nor flow out outside the impact head 200. A part of the impact terminal 240 is located in the internal flow channel 210, and the impact terminal 240 can exchange heat with the medium in the internal flow channel 210.

[0090] Among them, the impact terminal 240 is made of a heat-conducting material.

[0091] A partition 243 is fixedly installed in the mating blind hole 220. The partition 243 is arranged perpendicular to the central axis of the drive shaft 140. The partition 243 is located at the end of the mating blind hole 220 away from the driver 111, and the partition 243 is arranged at an interval from the drive shaft 140.

[0092] A stopper 241 is fixedly connected to the end of the impact terminal 240 close to the mating blind hole 220. The outer diameter of the stopper 241 is larger than the mounting hole. A third elastic member 242 is abutted between the partition 243 and the stopper 241. The third elastic member 242 continuously provides a thrust to the impact terminal 240 to promote the movement of the impact terminal 240 outside the impact head 200.

[0093] Among them, the elastic forces of the second elastic member 142 and the third elastic member 242 are related to the magnitude of the impact force when the impact terminal 240 impacts the microcrystalline glass panel 2000 to be tested. The elastic forces of the second elastic member 142 and the third elastic member 242 can be adjusted according to actual needs to achieve the purpose of adjusting the impact force.

[0094] Please combine Figure 9 , and the inner side wall of the mating blind hole 220 is provided with a first guiding groove 250 and a second guiding groove 260.

[0095] The first guiding groove 250 extends spirally along the inner side wall of the mating blind hole 220, and the second guiding groove 260 extends along the axial direction of the mating blind hole 220. The first guiding groove 250 and the second guiding groove 260 are distributed in sequence along the circumferential direction of the mating blind hole 220.

[0096] The ends of the first guiding groove 250 and the second guiding groove 260 close to the driver 111 are communicated with each other, and the ends of the first guiding groove 250 and the second guiding groove 260 away from the driver 111 are communicated with each other.

[0097] A mating block 143 is fixedly arranged on the side wall at the end of the drive shaft 140. The mating block 143 is used for slidingly mating in the first guiding groove 250 and the second guiding groove 260, so that during the rotation of the drive shaft 140, the impact head 200 can perform a reciprocating motion along the axial direction of the drive shaft 140, thereby enabling the impact terminal 240 to periodically impact the microcrystalline glass panel 2000 to be tested mounted on the test bench 300.

[0098] In this embodiment, a third guiding groove 270 is further arranged between the first guiding groove 250 and the second guiding groove 260. The third guiding groove 270 extends along the circumferential direction of the mating blind hole 220. The third guiding groove 270 is located at the end of the first guiding groove 250 and the second guiding groove 260 away from the driver 111. The end of the first guiding groove 250 away from the driver 111 and the end of the second guiding groove 260 away from the driver 111 are respectively communicated with both ends of the third guiding groove 270.

[0099] The first guiding groove 250, the third guiding groove 270 and the second guiding groove 260 together form a set of guiding groove bodies.

[0100] There are at least two sets of guiding groove bodies, and the guiding groove bodies are arranged in sequence along the circumferential direction of the mating blind hole 220. In this embodiment, there are two sets of guiding groove bodies.

[0101] For these two sets of guiding groove bodies, their heads and tails are connected. Specifically, the end of the first guiding groove 250 of one set of guiding groove bodies close to the driver 111 is communicated with the end of the second guiding groove 260 of the other set of guiding groove bodies close to the driver 111.

[0102] For all the guiding groove bodies, at least one of the third guiding grooves 270 is located on the side of the other third guiding groove 270 away from the driver 111. In the two sets of guiding groove bodies in this embodiment, the third guiding groove 270 of one set of guiding groove bodies is located on the side of the third guiding groove 270 of the other set of guiding groove bodies away from the driver 111. That is to say, the distance from the third guiding groove 270 of one set of guiding groove bodies to the driver 111 is greater than the distance from the third guiding groove 270 of the other set of guiding groove bodies to the driver 111.

[0103] In this embodiment, along the circumferential direction of the drive shaft 140, the central angle degrees corresponding to the spans of the first guiding groove 250 and the third guiding groove 270 are the same.

[0104] Furthermore, the switch control mechanism 600 includes: a reference member 610, a mating arm 620, a first pipe 630, a second pipe 640 and a third pipe 650.

[0105] The reference member 610 is fixedly installed on the limiting frame 230. The reference member 610 is annular, and the reference member 610 is disposed around the drive shaft 140. The drive shaft 140 can rotate relative to the reference member 610.

[0106] The mating arm 620 is fixedly connected to the impact head 200. The mating arm 620 is arranged along the axial direction of the drive shaft 140. The mating arm 620 is in contact with the reference member 610 and slidably mates with the reference member 610.

[0107] The first pipe 630 and the second pipe 640 are embedded in the reference member 610. One end of each of the first pipe 630 and the second pipe 640 penetrates through to the mating surface of the reference member 610 and the mating arm 620, and the other ends of the first pipe 630 and the second pipe 640 extend outside the reference member 610.

[0108] At the mating surface of the reference member 610 and the mating arm 620, the ends of the first pipe 630 and the second pipe 640 are arranged at intervals along the axial direction of the drive shaft 140.

[0109] One end of the first pipe 630 away from the mating surface is used to communicate with the outlet 912 of the temporary storage mechanism 900 that communicates with the first container 400, and one end of the second pipe 640 away from the mating surface is used to communicate with the outlet 912 of the temporary storage mechanism 900 that communicates with the second container 500.

[0110] The third pipe 650 is installed on the mating arm 620. The end of the third pipe 650 penetrates through to the mating surface of the mating arm 620 and the reference member 610. One end of the third pipe 650 away from the mating surface is used to communicate with the internal flow channel 210.

[0111] The working principle of the machinable glass panel structure strength detection device is as follows: During the process of the driver 111 driving the drive shaft 140 to rotate, for example, taking the drive mechanism 100 in the Figures 4-6 shown state as the starting state, the rotation direction of the drive shaft 140 is Figures 4-6 the clockwise rotation direction in the shown perspective. At the Figures 4-6 shown state, the mating block 143 of the drive shaft 140 is located at Figure 9At the P1 position in it, that is, the mating block 143 is located in the guiding groove body corresponding to the third guiding groove 270 closer to the driver 111, and is located at one end of the first guiding groove 250 of the guiding groove body closer to the driver 111. At this time, the third pipeline 650 is located on the side away from the driver 111 of both the first pipeline 630 and the second pipeline 640, and the mating arm 620 closes one end of the first pipeline 630 and the second pipeline 640 located on the mating surface. In this state, the second cylinder body 810 of the temporary storage mechanism 900 communicated with the second container 500 stores the cold medium corresponding to the second container 500, and the amount of the stored cold medium is the same as the amount of one suction / release of the second cylinder body 810, and the temporary storage mechanism 900 communicated with the first container 400 is empty and does not store any medium.

[0112] As the drive shaft 140 continues to rotate, the mating block 143 of the drive shaft 140 moves along the first guiding groove 250 and moves toward one end of the first guiding groove 250 away from the driver 111. Therefore, under the action of the mating block 143 and the first guiding groove 250, the impact head 200 moves axially along the drive shaft 140 toward the side where the driver 111 is located, and the second elastic member 142 is compressed.

[0113] In this process, due to the mating relationship between the second runner 132 and the drive shaft 140, the drive shaft 140 will move along the length direction of the first slide rail 110, and at the same time, the second slider 131 will also move along the third slide rail 130 to Figures 4-6 Taking the perspective shown as an example, the drive shaft 140 will move to the right. Therefore, it can drive the driver 111 to move to the right along the first slide rail 110, drive the first runner 122 to move to the right, drive the first slider 121 to move to the right along the second slide rail 120, drive the second runner 132 to move to the right, and drive the second slider 131 to move to the right along the third slide rail 130. In this way, the first slider 121 can pull the first piston 720 to suck the hot medium in the first container 400 into the first cylinder body 710, and the second slider 131 can pull the second piston 820 to suck the cold medium in the second container 500 into the second cylinder body 810.

[0114] When the drive shaft 140 rotates 90°, the drive mechanism 100 enters Figures 10-12 the state shown. At this time, the first slider 121 moves to the rightmost stop point, and the suction amount of the medium in the first cylinder body 710 reaches the maximum. The second slider 131 moves to the middle of the sliding stroke. The mating block 143 of the drive shaft 140 is located at Figure 9At the P2 position in it, the third pipe 650 moves to the second pipe 640 and communicates with the second pipe 640. One end of the third pipe 650 located at the fitting surface is closed by the fitting arm 620. In this state, the temporary storage mechanism 900 communicating with the second container 500 starts to convey the cold medium to the third pipe 650 through the second pipe 640. The cold medium enters the internal flow channel 210 through the third pipe 650 to cool the impact terminal 240.

[0115] When the drive shaft 140 continues to rotate, the fitting block 143 will move along the third guiding groove 270 towards the second guiding groove 260, and the axial position of the impact head 200 on the drive shaft 140 remains unchanged. The second slider 131 will further move upward along the third slide rail 130, and the drive shaft 140 will drive the first slider 121 and the driver 111 to move leftward. During this process, the temporary storage mechanism 900 communicating with the second container 500 continuously starts to convey the cold medium to the third pipe 650 through the second pipe 640. The second piston 820 continues to suck the cold medium in the second container 500 into the second cylinder body 810, and the first piston 720 will start to push the hot medium in the first cylinder body 710 into the temporary storage mechanism 900 communicating therewith.

[0116] When the drive shaft 140 rotates another 90°, the drive mechanism 100 enters Figures 13-15 the state shown. At this time, the second slider 131 moves to the uppermost stop point, and the suction amount of the medium in the second cylinder body 810 reaches the maximum. The first slider 121 moves to the middle of the sliding stroke, and a part of the hot medium in the first cylinder body 710 is pushed into the temporary storage mechanism 900 communicating therewith. In this state, the fitting block 143 is located at Figure 9 the P3 position in it.

[0117] Among them, the temporary storage mechanism 900 communicating with the second container 500 needs to discharge all the cold medium in the second cylinder body 810 before the fitting block 143 reaches P3, which can be specifically achieved by adjusting the elastic force of the first elastic member 930, the inner diameter of the discharge port 912, the inner diameter of the second pipe 640, the inner diameter of the third pipe 650, the inner diameter of the internal flow channel 210, the inner diameter of the discharge port 211, and is not limited thereto.

[0118] That is to say, when the mating block 143 reaches P3, all the cold medium in the temporary storage mechanism 900 communicated with the second container 500 has been discharged, and the impact terminal 240 is fully cooled by the cold medium. At the same time, since the mating block 143 can move along the second guiding groove 260, under the elastic force of the second elastic member 142, the impact head 200 moves axially along the driving shaft 140 to reset. The impact head 200 carries the impact terminal 240 to impact the microcrystalline glass panel 2000 to be tested installed on the test bench 300, and the impact terminal 240 is in a low-temperature state during the impact, realizing the simulation of low-temperature impact. The third pipe 650 is disconnected from the second pipe 640 again, and the mating block 143 moves to Figure 9 the P4 position in

[0119] When the driving shaft 140 continues to rotate, the mating block 143 enters the first guiding groove 250 of another set of guiding groove bodies and moves along the first guiding groove 250. During this process, the first slider 121 continues to push the hot medium in the first cylinder 710 into the temporary storage mechanism 900 communicated therewith, and the second slider 131 begins to push the cold medium in the second cylinder 810 into the temporary storage mechanism 900 communicated therewith.

[0120] When the driving shaft 140 rotates another 90°, the driving mechanism 100 enters Figures 16-18 the state shown in. At this time, the first slider 121 pushes all the hot medium in the first cylinder 710 into the temporary storage mechanism 900 communicated therewith, the second slider 131 pushes a part of the cold medium in the second cylinder 810 into the temporary storage mechanism 900 communicated therewith, and the mating block 143 is located at Figure 9 the P5 position in. The third pipe 650 moves to the first pipe 630 and communicates with the first pipe 630, and the second pipe 640 is closed by the mating arm 620. Although the third pipe 650 will be briefly communicated with the second pipe 640 before moving to the teeth of the first pipe 630, since the communication time is short, not too much cold medium will enter the third pipe body and there will be no obvious influence. At this time, the impact head 200 moves axially along the driver 111 again and moves away from the test bench 300.

[0121] When the mating block 143 reaches Figure 9 the P5 position in, the temporary storage mechanism 900 communicated with the first container 400 starts to convey the hot medium to the third pipe 650 through the first pipe 630, and the hot medium enters the internal flow channel 210 to heat the impact terminal 240.

[0122] When the driving shaft 140 continues to rotate, the first slider 121 starts to suck the hot medium in the first container 400 into the first cylinder 710 by using the first piston 720 again, and the second slider 131 continues to push the cold medium in the second cylinder 810 into the temporary storage mechanism 900 communicated therewith.

[0123] After the drive shaft 140 rotates another 90°, the drive mechanism 100 returns to the Figures 4-6 state shown, and the mating block 143 reaches the Figure 9 P6 position in. The temporary storage mechanism 900 communicated with the first container 400 needs to discharge all the heat medium in the first cylinder 710 before the mating block 143 reaches P6.

[0124] The mating block 143 can return to the P1 position along the second guiding groove 260, and the impact head 200 can carry the impact terminal 240 again to impact the microcrystalline glass panel 2000 to be tested installed on the test bench 300, realizing the simulation of high-temperature impact.

[0125] Based on the above process, if the drive shaft 140 continues to rotate, a cycle can be achieved to realize hot and cold alternating impacts.

[0126] Furthermore, the test bench 300 is slidably fitted to the fourth slide rail 310, and the fourth slide rail 310 is arranged parallel to the second slide rail 120. The limit frame 230 is fixedly connected to the test bench 300. With this design, during the test, the limit frame 230 and the test bench 300 will move along with the movement of the drive shaft 140 to ensure that the impact terminal 240 continuously impacts the same position of the microcrystalline glass panel 2000 to be tested.

[0127] In summary, the microcrystalline glass panel structural strength detection device provided by the embodiment of the present invention can perform targeted tests on the structural strength of the microcrystalline glass panel according to the application scenarios in the actual use process. The test process has a higher degree of fit with the actual application scenario, which helps to improve the credibility of the test results and makes the test results more valuable for reference.
