Description

Technical Field

[0001] This application relates to the field of microcrystalline glass analysis technology, and more specifically, to a microcrystalline glass sheet structure stability analysis system. Background Technology

[0002] Microcrystalline glass has a wide range of applications, and for different application scenarios, microcrystalline glass sheets with corresponding properties need to be matched.

[0003] The actual performance of glass-ceramics is related to its composition, processing shape, volume / area size, and processing technology. Therefore, for different application scenarios, it is necessary to conduct performance tests on the corresponding glass-ceramics sheets to ensure that they meet the usage requirements.

[0004] Sudden temperature changes are one of the main factors affecting the structural stability of glass-ceramic sheets. To ensure the structural stability of glass-ceramic sheets under different temperature changes, it is often necessary to conduct stability tests on the corresponding glass-ceramic sheets in advance. Currently, the common method is to repeatedly heat and cool the glass-ceramic sheets to test their structural stability after temperature changes. However, the testing efficiency of existing testing equipment is low, and the process is cumbersome. Summary of the Invention

[0005] The purpose of this application is to provide a structural stability analysis system for microcrystalline glass sheets, which can efficiently perform alternating heating and cooling operations on the microcrystalline glass sheets under test, is simple and convenient, and can detect the structural stability of the microcrystalline glass sheets under test under different temperature changes.

[0006] The embodiments of this application are implemented as follows:

[0007] A system for analyzing the structural stability of microcrystalline glass sheets includes: a sample stage, a guide rail, a motion seat, a reference ring, a mating wheel, a control module, a cold medium supply module, a hot medium supply module, and a drive assembly.

[0008] The sample stage is used to mount the microcrystalline glass substrate to be tested. The guide rail is perpendicular to the sample stage, and the motion seat is slidably fitted onto the guide rail. The motion seat is equipped with an extension arm, which slides along a direction perpendicular to the guide rail. An impact head is mounted on the side of the motion seat closest to the sample stage.

[0009] The reference ring is fixedly positioned at a distance from the sample stage. The central axis of the reference ring is parallel to the surface of the sample stage.

[0010] The mating wheel has an external gear ring, and the reference ring has an internal gear ring. The mating wheel meshes with the reference ring.

[0011] A disc is provided on the side wall of the mating wheel. The disc is coaxial with the mating wheel and rotates to engage with the mating wheel. The extension arm is fixedly connected to the disc.

[0012] Both the cold medium supply module and the hot medium supply module work in conjunction with the control module.

[0013] The drive assembly drives the mating wheel to move circumferentially along the reference ring, enabling the mating wheel to roll along the internal gear ring of the reference ring. This drives the motion seat to move closer to and away from the sample stage, thereby causing the impact head to periodically impact the glass-ceramic substrate under test. The mating wheel also drives the control module, which in turn controls the cold medium supply module and the hot medium supply module to alternately supply media to the glass-ceramic substrate under test, thus causing temperature changes in the substrate.

[0014] Furthermore, the cold medium supply module includes: a cold medium storage device, a cold medium supply pipe, and a cold medium delivery pipe, with the cold medium supply pipe connected to the cold medium storage device.

[0015] The heat medium supply module includes a heat medium storage device, a heat medium supply pipe, and a heat medium delivery pipe, with the heat medium storage device connected to the heat medium supply pipe.

[0016] The mating wheel includes a base, a first baffle, a second baffle, and an outer ring. The base is cylindrical, and both the first and second baffles are circular plates with the same diameter. The diameter of the base is smaller than the diameters of the first and second baffles. The first and second baffles are coaxially fixed to the two end faces of the base.

[0017] The outer ring is disposed around the periphery of the first and second baffles, and rotates to fit with the first and second baffles, forming a rotatable seal. The inner ring wall of the outer ring, the outer wall of the base, the first baffle, and the second baffle together form a guide cavity. The outer gear ring of the mating wheel is disposed on the outer ring.

[0018] The substrate has through holes that pass through it, and these through holes are arranged radially along the substrate. Along the axial direction of the substrate, the through holes extend to both end faces of the substrate.

[0019] The control module includes: a control block and a control tongue.

[0020] The control block is fixedly connected to the inner ring wall of the outer ring body. The first baffle and the second baffle are both in contact with the control block. The outer side wall of the base body is also in contact with the control block. The control block extends in an arc shape along the circumference of the outer ring body.

[0021] The control tongue slides within the mating through hole, with its outer wall fitting against the inner wall of the through hole. The control tongue has a first end and a second end opposite to each other.

[0022] A first flow channel for communicating with the guide cavity is provided on one side of the first end, and a second flow channel for communicating with the guide cavity is provided on the side of the first end away from the first flow channel. Both the first flow channel and the second flow channel extend into the interior of the control tongue, and the other ends of the first flow channel and the second flow channel extend to the side wall of the control tongue near the first baffle.

[0023] A third flow channel for communicating with the guide cavity is provided on one side of the second end, and a fourth flow channel for communicating with the guide cavity is provided on the side of the second end away from the third flow channel. Both the third and fourth flow channels extend into the interior of the control tongue, and the other ends of the third and fourth flow channels extend to the side wall of the control tongue near the second baffle.

[0024] The first baffle has a first opening for communicating with the first flow channel and a second opening for communicating with the second flow channel. The second baffle has a third opening for communicating with the third flow channel and a fourth opening for communicating with the fourth flow channel.

[0025] Disc body: includes a first turntable and a second turntable. The first turntable is fitted onto the side of the first baffle away from the base, and the second turntable is fitted onto the side of the second baffle away from the base. Both the first and second turntables are fixedly connected to the extension arm.

[0026] The first turntable has a first annular groove and a second annular groove on the side near the first baffle. A first opening communicates with the first annular groove, and a second opening communicates with the second annular groove. A cold medium supply pipe communicates with the first annular groove, and a hot medium delivery pipe communicates with the second annular groove.

[0027] The second turntable has a third annular groove and a fourth annular groove on the side near the second baffle. The third opening communicates with the third annular groove, and the fourth opening communicates with the fourth annular groove. The hot medium supply pipe communicates with the third annular groove, and the cold medium delivery pipe communicates with the fourth annular groove.

[0028] Both the hot medium delivery tube and the cold medium delivery tube extend to the sample stage at the other end.

[0029] At least one of the first baffle and the second baffle is in transmission engagement with the drive assembly.

[0030] The outer ring has a first rotation stop, a second rotation stop, a third rotation stop, and a fourth rotation stop.

[0031] When the outer ring is at the first rotation stop point, the first end is in contact with the outer ring, the second end is in the mating through hole, one end of the control block is in contact with the first end, and the other end of the control block is just separated from the edge of the second end of the mating through hole.

[0032] When the outer ring is at the second rotation stop point, one end of the control block pushes the first end into the mating through hole, and the second end fits against the outer ring.

[0033] When the outer ring is at the third rotation stop point, the second end is in contact with the outer ring, the first end is in the mating through hole, one end of the control block is in contact with the second end, and the other end of the control block is just separated from the edge of the first end of the mating through hole.

[0034] When the outer ring is at the fourth rotation stop, one end of the control block pushes the second end into the mating through hole, and the first end fits against the outer ring.

[0035] Furthermore, both the first and second ends have wedge-shaped portions on their end faces. The front end of the control block is wedge-shaped along the rotation direction of the outer ring.

[0036] Furthermore, the extension arm is arranged radially along the first and second turntables.

[0037] Furthermore, the outlet ends of both the hot medium delivery pipe and the cold medium delivery pipe extend to the surface of the sample stage.

[0038] Furthermore, the sample stage has an inner cavity, through which both the hot medium delivery pipe and the cold medium delivery pipe are connected.

[0039] The sample stage is also equipped with an output pipe for discharging the medium from the inner cavity.

[0040] Furthermore, the side of the sample stage used to mount the microcrystalline glass substrate to be tested is made of a thermally conductive material.

[0041] Furthermore, the drive components include: a driver, a drive ring, and a connector.

[0042] The drive ring is mounted on the reference ring and rotatably fitted to the reference ring. The drive ring is driven by the driver.

[0043] At least one of the first baffle and the second baffle is fixedly connected to the drive ring by a connector.

[0044] The beneficial effects of the technical solutions in this application include:

[0045] The microcrystalline glass substrate structural stability analysis system provided in this application requires only a single power input from the driver to achieve alternating delivery of hot and cold media. This allows for the heating and cooling of the microcrystalline glass substrate on the sample stage using the hot and cold media, simulating a scenario of rapid temperature change. During this process, the moving seat performs an impact test on the microcrystalline glass substrate using an impact head. If cracks or fragments appear in the microcrystalline glass substrate, it indicates that the structural strength of the microcrystalline glass substrate is insufficient.

[0046] Meanwhile, since the control block can act as both a suction and discharge medium, neither the cold medium supply module nor the hot medium supply module needs to be equipped with an additional power source for transporting the medium, making it more environmentally friendly. The structure of the cold medium supply module and the hot medium supply module is also more streamlined.

[0047] Overall, the microcrystalline glass substrate structural stability analysis system provided in this application embodiment can efficiently perform alternating heating and cooling operations on the microcrystalline glass substrate under test, which is simple and convenient, and can detect the structural stability of the microcrystalline glass substrate under test under different temperature changes.

[0071] The technical solutions of this application will be described by way of example through some embodiments below.

[0072] See Figures 1-9 This application provides a structural stability analysis system for microcrystalline glass sheets, used to detect the structural stability of microcrystalline glass sheets under conditions of rapid temperature changes.

[0073] The microcrystalline glass sheet structure stability analysis system includes: a frame (not shown in the figure), a sample stage 100, a guide rail 110, a motion seat 120, a reference ring 200, a mating wheel 300, a control module, a cold medium supply module, and a hot medium supply module.

[0074] The sample stage 100 is fixedly installed on the frame. In this embodiment, the sample stage 100 is horizontally positioned. The sample stage 100 is used to mount the microcrystalline glass substrate to be tested.

[0075] The guide rail 110 is arranged perpendicular to the sample stage 100. In this embodiment, the guide rail 110 is arranged in the vertical direction and located above the sample stage 100.

[0076] The motion seat 120 is fitted to the guide rail 110. Along the length of the guide rail 110, the motion seat 120 is slidably fitted to the guide rail 110, and along the direction perpendicular to the guide rail 110, the motion seat 120 is fixedly fitted to the guide rail 110.

[0077] The motion seat 120 is fitted with an extension arm 130, which, in this embodiment, is perpendicular to the guide rail 110. The extension arm 130 slides along the motion seat 120 in a direction perpendicular to the guide rail 110, i.e., along the length of the extension arm 130. An impact head 140 is mounted on the side of the motion seat 120 near the sample stage 100. The impact head 140 is perpendicular to the sample stage 100 and is used to impact the microcrystalline glass substrate to be tested, which is mounted on the sample stage 100, to detect the structural stability of the microcrystalline glass substrate.

[0078] In this embodiment, along the length of the guide rail 110, the impact head 140 is slidably fitted onto the motion seat 120, and an elastic element abuts between the impact head 140 and the motion seat 120. When the impact head 140 impacts the microcrystalline glass substrate to be tested, the elastic element can be elastically compressed, thereby allowing the impact head 140 to approach the motion seat 120. The impact force of the impact head 140 on the microcrystalline glass substrate to be tested can be adjusted by adjusting the elastic coefficient of the elastic element.

[0079] The reference ring 200 is fixedly installed on the frame, and is spaced apart from the sample stage 100. The central axis of the reference ring 200 is parallel to the surface of the sample stage 100.

[0080] The central axis of the mating wheel 300 is parallel to the central axis of the reference ring 200. The mating wheel 300 has an external gear ring, and the reference ring 200 has an internal gear ring. The mating wheel 300 meshes with the reference ring 200. When the mating wheel 300 moves along the circumference of the reference ring 200, it will rotate synchronously under the action of the external and internal gear rings.

[0081] The mating wheel 300 has a disc on its side wall, which is coaxial with the mating wheel 300 and rotates to engage with the mating wheel 300. The extension arm 130 is fixedly connected to the disc.

[0082] Both the cold medium supply module and the hot medium supply module work in conjunction with the control module.

[0083] The drive assembly drives the mating wheel 300 to move circumferentially along the reference ring 200, enabling the mating wheel 300 to roll along the internal gear ring of the reference ring 200. This drives the motion seat 120 to move closer to and away from the sample stage 100, thereby causing the impact head 140 to periodically impact the microcrystalline glass substrate under test. The mating wheel 300 also drives the control module, which controls the cold medium supply module and the hot medium supply module to alternately supply medium to the microcrystalline glass substrate under test, thereby causing the temperature of the microcrystalline glass substrate under test to change.

[0084] Specifically, the cold medium supply module includes: a cold medium storage device (not shown in the figure), a cold medium supply pipe 610, and a cold medium delivery pipe 620, with the cold medium supply pipe 610 connected to the cold medium storage device.

[0085] The heat medium supply module includes: a heat medium storage device (not shown in the figure), a heat medium supply pipe 630, and a heat medium delivery pipe 640. The heat medium storage device is connected to the heat medium supply pipe 630.

[0086] The mating wheel 300 includes: a base 310, a first baffle 320, a second baffle 330, and an outer ring 340.

[0087] The base 310 is cylindrical, and the first baffle 320 and the second baffle 330 are both circular plates with the same diameter. The diameter of the base 310 is smaller than the diameters of the first baffle 320 and the second baffle 330. The first baffle 320 and the second baffle 330 are coaxially fixed to the two end faces of the base 310.

[0088] The outer ring 340 is disposed around the periphery of the first baffle 320 and the second baffle 330. The outer ring 340 is rotatably fitted with the first baffle 320 and the second baffle 330, and the outer ring 340 is rotatably sealed with the first baffle 320 and the second baffle 330.

[0089] The inner ring wall of the outer ring body 340, the outer ring wall of the base body 310, the side wall of the first baffle 320 near the second baffle 330, and the side wall of the second baffle 330 near the first baffle 320 together form a flow guiding cavity. The flow guiding cavity is annular.

[0090] The outer gear ring of the mating wheel 300 is located on the outer ring wall of the outer ring body 340.

[0091] The base 310 has a through hole 311 extending through it, and the through hole 311 is arranged radially along the base 310. Along the axial direction of the base 310, the through hole 311 extends to both end faces of the base 310. That is to say, the through hole 311 effectively divides the base 310 into two symmetrical parts of the same size.

[0092] In this embodiment, the cross-section of the cavity that mates with the through hole 311 is rectangular.

[0093] The control module includes: control block 400 and control tongue 500.

[0094] The control block 400 is fixedly connected to the inner ring wall of the outer ring body 340, and extends in an arc shape along the circumference of the outer ring body 340. Specifically, the sidewall of the control block 400 closest to the base 310 is in contact with the outer wall of the base 310, the sidewall of the control block 400 closest to the first baffle 320 is in contact with the first baffle 320, and the sidewall of the control block 400 closest to the second baffle 330 is in contact with the second baffle 330. In other words, the control block 400 is actually fan-shaped.

[0095] When the outer ring 340 rotates relative to the first baffle 320 and the second baffle 330, the control block 400 rotates together with the outer ring 340, that is, the control block 400 slides relative to the surfaces of the base 310, the first baffle 320, and the second baffle 330. During the relative sliding process, there is a sliding seal between the control block 400 and the base 310, between the control block 400 and the first baffle 320, and between the control block 400 and the second baffle 330.

[0096] The control tongue 500 is fitted into the mating through hole 311. Along the length of the mating through hole 311, the control tongue 500 slides within it. Along the circumference of the mating through hole 311, the control tongue 500 is fixedly fitted into it. The main body of the control tongue 500 has a rectangular cross-section, and the outer wall of the control tongue 500 is in contact with and slides to seal the inner wall of the mating through hole 311.

[0097] The control tongue 500 has a first end 510 and a second end 520. The shape of the end face of both the first end 510 and the second end 520 is adapted to the inner ring wall of the outer ring body 340 so that when either the first end 510 or the second end 520 is in contact with the inner ring wall of the outer ring body 340, the flow guide cavity can be cut off.

[0098] Apart from the side wall of the first end 510 near the first baffle 320 and the side wall of the first end 510 near the second baffle 330, a first flow channel 511 for communicating with the flow guide cavity is provided on one side wall of the first end 510, and a second flow channel 512 for communicating with the flow guide cavity is provided on the side of the first end 510 away from the first flow channel 511.

[0099] Both the first flow channel 511 and the second flow channel 512 extend into the interior of the control tongue 500 and extend along the length of the control tongue 500. The other ends of the first flow channel 511 and the second flow channel 512 extend to the side wall of the control tongue 500 near the first baffle 320. Both the first flow channel 511 and the second flow channel 512 form an opening on the side wall of the control tongue 500 near the first baffle 320.

[0100] Apart from the side wall of the second end 520 near the first baffle 320 and the side wall of the second baffle 330, a third flow channel 521 for communicating with the flow guide cavity is provided on one side of the second end 520, and a fourth flow channel 522 for communicating with the flow guide cavity is provided on the side of the second end 520 away from the third flow channel 521.

[0101] Both the third flow channel 521 and the fourth flow channel 522 extend into the interior of the control tongue 500 and extend along the length of the control tongue 500. The other ends of the third flow channel 521 and the fourth flow channel 522 extend to the side wall of the control tongue 500 near the second baffle 330. Both the third flow channel 521 and the fourth flow channel 522 form an opening on the side wall of the control tongue 500 near the first baffle 320.

[0102] The first baffle 320 has a first opening 321 for communicating with the first flow channel 511 and a second opening 322 for communicating with the second flow channel 512. The second baffle 330 has a third opening 331 for communicating with the third flow channel 521 and a fourth opening 332 for communicating with the fourth flow channel 522.

[0103] The disk body includes the first turntable 710 and the second turntable 720.

[0104] The first turntable 710 is rotatably fitted to the side of the first baffle 320 away from the base 310, and the first turntable 710 and the first baffle 320 are coaxially arranged. The second turntable 720 is rotatably fitted to the side of the second baffle 330 away from the base 310, and the second turntable 720 and the second baffle 330 are coaxially arranged.

[0105] The first turntable 710 and the second turntable 720 are both fixedly connected to the extension arm 130. In this embodiment, the extension arm 130 is arranged radially along the first turntable 710 and the second turntable 720.

[0106] The first turntable 710 has a first annular groove 711 and a second annular groove 712 on the side near the first baffle 320. The first annular groove 711 and the second annular groove 712 are both coaxially arranged with the first turntable 710, and the inner diameter of the first annular groove 711 is larger than the outer diameter of the second annular groove 712.

[0107] The first opening 321 is connected to the first annular groove 711, and the second opening 322 is connected to the second annular groove 712. When the first turntable 710 rotates relative to the first baffle 320, the first opening 321 and the first annular groove 711 remain connected, and the second opening 322 and the second annular groove 712 remain connected.

[0108] The cold medium supply pipe 610 is connected to the side of the first turntable 710 away from the first baffle 320, and the cold medium supply pipe 610 is connected to the first annular groove 711.

[0109] The heat medium delivery pipe 640 is connected to the side of the first turntable 710 away from the first baffle 320, and the heat medium delivery pipe 640 is connected to the second annular groove 712.

[0110] The second turntable 720 has a third annular groove 721 and a fourth annular groove 722 on the side near the second baffle 330. Both the third annular groove 721 and the fourth annular groove 722 are coaxially arranged with the second turntable 720, and the inner diameter of the third annular groove 721 is larger than the outer diameter of the fourth annular groove 722.

[0111] The third opening 331 is connected to the third annular groove 721, and the fourth opening 332 is connected to the fourth annular groove 722. When the second turntable 720 rotates relative to the second baffle 330, the third opening 331 and the third annular groove 721 remain connected, and the fourth opening 332 and the fourth annular groove 722 remain connected.

[0114] The other ends of both the hot medium delivery pipe 640 and the cold medium delivery pipe 620 extend to the sample stage 100.

[0115] At least one of the first baffle 320 and the second baffle 330 is in transmission engagement with the drive assembly.

[0116] Specifically, the drive components include: a driver (not shown in the figure), a drive ring 800, and a connector 810.

[0117] A drive ring 800 is disposed around a reference ring 200, and the drive ring 800 and the reference ring 200 are coaxially arranged. The drive ring 800 is rotatably fitted with the outer ring wall of the reference ring 200. The drive ring 800 is driven by a driver so that the drive ring 800 can rotate relative to the reference ring 200.

[0118] At least one of the first baffle 320 and the second baffle 330 is fixedly connected to the drive ring 800 by the connector 810.

[0119] In this embodiment, the connector 810 is located on the side of the drive ring 800 near the first baffle 320. One end of the connector 810 is fixedly connected to the drive ring 800, and the other end of the connector 810 is fixedly connected to the side of the first baffle 320 away from the second baffle 330. The outer ring body 340 is spaced apart from the connector 810, and the end of the connector 810 near the first baffle 320 is spaced apart from the first turntable 710. The connector 810 is located on the side of the extension arm 130 near the first baffle 320.

[0120] In this embodiment, both the first end 510 and the second end 520 have wedge-shaped portions on their end faces. When the drive assembly drives the mating wheel 300 to move circumferentially along the reference ring 200, the outer ring body 340 will rotate relative to the first baffle 320 and the second baffle 330. Along the rotation direction of the outer ring body 340, the front end of the control block 400 (hereinafter referred to as the "front end") is wedge-shaped.

[0121] In this embodiment, the inner diameter of the reference ring 200 is twice the outer diameter of the mating wheel 300 (outer diameter of the outer ring body 340), but it is not limited to this. The size ratio between the two can be flexibly set according to actual needs, and this application does not make specific limitations.

[0122] During operation, the outer ring body 340 has a first rotation stop, a second rotation stop, a third rotation stop, and a fourth rotation stop.

[0123] When the outer ring 340 is at the first rotation dead point: the mating wheel 300 is located at the highest position of the inner ring wall of the reference ring 200, such as... Figure 1 As shown, at this time, the distance between the motion seat 120 and the sample stage 100 is also the farthest. In this state, the first end 510 of the control tongue 500 is in contact with the outer ring body 340, and the control tongue 500 uses the first end 510 to break the guide cavity. The second end 520 is located in the mating through hole 311. The front end of the control block 400 contacts and fits with the side of the first end 510 where the second flow channel 512 is opened. The other end of the control block 400 is just separated from the edge of the second end 520 of the mating through hole 311, as shown. Figure 8 As shown.

[0124] For example, we take the state when the outer ring 340 is at the first rotation stop as the starting state. When the drive ring 800 drives the mating wheel 300 along the circumference of the reference ring 200 via the connector 810... Figure 1 When moving clockwise in the view shown, the outer ring 340 will move along... Figure 1As shown in the view, the rotation is counterclockwise. During this process, the control block 400 pushes the first end 510 and pushes the first end 510 into the mating through hole 311. After the drive ring 800 rotates a certain angle, the outer ring body 340 enters the second rotation stop point.

[0125] When the outer ring 340 is at the second rotation stop: the front end of the control block 400 pushes the first end 510 into the mating through hole 311, and at the same time, the second end 520 is pushed out of the mating through hole 311, so that the second end 520 fits against the outer ring 340. In this state, the second end 520 breaks the flow guide cavity. Figure 9 As shown. At this time, since the first end 510 is pushed into the mating through hole 311, the openings of the first flow channel 511 and the second flow channel 512 are closed. Since the second end 520 extends out, the third flow channel 521 and the fourth flow channel 522 are connected to the guide cavity.

[0126] As the drive ring 800 continues to drive the mating wheel 300 to move, the distance between the front end and the second end 520 of the control block 400 gradually decreases, while the distance between the other end (rear end) of the control block 400 and the second end 520 gradually increases. Since the second end 520 breaks the flow guide cavity, the medium between the front end and the second end 520 of the control block 400 and the medium between the rear end and the second end 520 of the control block 400 are isolated from each other and do not interfere with each other.

[0127] When the drive ring 800 continues to drive the mating wheel 300, the control block 400 acts like a piston, drawing the hot medium from the hot medium supply pipe 630 and the hot medium storage into the area between the rear end and the second end 520 of the control block 400 through the third flow channel 521. At the same time, the medium (cold medium) originally between the front end and the second end 520 of the control block 400 can be transported to the cold medium delivery pipe 620 through the fourth flow channel 522, thereby transporting the cold medium to the sample stage 100 for temperature regulation of the microcrystalline glass substrate to be tested.

[0128] As the drive ring 800 continues to drive the mating wheel 300, the outer ring body 340 will enter the third rotation dead point.

[0129] When the outer ring 340 is at the third rotation stop: in the height direction, the mating wheel 300 is located at the middle position of the inner ring wall of the reference ring 200, such as... Figure 10 As shown, at this point, the distance between the motion seat 120 and the sample stage 100 becomes closer. In this state,

[0130] The second end 520 of the control tongue 500 is fitted to the outer ring body 340, the first end 510 is located inside the mating through hole 311, the front end of the control block 400 contacts and fits against the side of the second end 520 where the fourth flow channel 522 is opened, and the other end of the control block 400 is just separated from the edge of the second end 520 where the mating through hole 311 is located. Figure 11 As shown. That is to say, at this time, the control block 400 has just discharged almost all of the cold medium between the front end and the second end 520 of the control block 400, while the intake of the hot medium between the rear end and the second end 520 of the control block 400 is also close to the maximum.

[0131] At this time, if the outer ring body 340 continues to rotate, the front end of the control block 400 will push the second end 520 into the mating through hole 311.

[0132] As the drive ring 800 continues to drive the mating wheel 300 to move, the outer ring body 340 will enter the fourth rotation dead point.

[0133] When the outer ring body 340 is at the fourth rotation stop point: the front end of the control block 400 pushes the second end 520 into the mating through hole 311, and the first end 510 is pushed out again, so that the first end 510 is once again in contact with the inner ring wall of the outer ring body 340, as... Figure 12 As shown.

[0134] In this state, the first end 510 breaks the flow guide cavity. At this time, since the second end 520 is pushed into the mating through hole 311, the openings of the third flow channel 521 and the fourth flow channel 522 are closed. Since the first end 510 extends out, the first flow channel 511 and the second flow channel 512 are connected to the flow guide cavity.

[0135] When the drive ring 800 continues to drive the mating wheel 300 to move, the distance between the front end of the control block 400 and the first end 510 will gradually decrease, and the distance between the other end (rear end) of the control block 400 and the first end 510 will gradually increase. Since the first end 510 breaks the flow channel, the medium between the front end of the control block 400 and the first end 510 and the medium between the rear end of the control block 400 and the first end 510 are isolated from each other and do not interfere with each other.

[0136] When the drive ring 800 continues to drive the mating wheel 300 to move, the control block 400 will continue to act like a piston. It can draw the cold medium from the cold medium supply pipe 610 and the cold medium storage into the area between the rear end and the first end 510 of the control block 400 through the first flow channel 511. At the same time, it can transport the medium (hot medium) originally between the front end and the first end 510 of the control block 400 to the hot medium delivery pipe 640 through the second flow channel 512, and then transport the hot medium to the sample stage 100 for temperature adjustment of the microcrystalline glass substrate to be tested.

[0137] When the drive ring 800 continues to drive the mating wheel 300 to move, causing the mating wheel 300 to move to the lowest position of the inner ring wall of the reference ring 200, as... Figure 13 As shown, at this time, the distance between the motion seat 120 and the sample stage 100 is the closest. The motion seat 120 impacts the microcrystalline glass plate to be tested, which is mounted on the sample stage 100, through the impact head 140, in order to detect the structural stability of the microcrystalline glass plate to be tested.

[0138] In this state, the outer ring 340 returns to its state at the first rotation dead center, as shown below. Figure 8 As shown, when the drive ring 800 continues to drive the mating wheel 300 to move, the outer ring body 340 will move sequentially between the first rotation stop point, the second rotation stop point, the third rotation stop point and the fourth rotation stop point, as described above.

[0139] And so on, as the drive ring 800 continues to drive the mating wheel 300 to move until... Figure 14 In the aforementioned state, the outer ring 340 returns to the state it was in at the third rotation dead center.

[0140] With the above design, only a single power input from the driver is needed to achieve the alternating delivery of hot and cold media. This allows for the heating and cooling of the microcrystalline glass substrate under test on the sample stage 100 using the hot and cold media, simulating a scenario of rapid temperature change. During this process, the motion seat 120 performs an impact test on the microcrystalline glass substrate under test via the impact head 140. If cracks or fragments appear on the microcrystalline glass substrate under test, it indicates that the structural strength of the microcrystalline glass substrate under test is insufficient.

[0141] Meanwhile, since the control block 400 can function as both a medium intake and a medium exhaust, neither the cold medium supply module nor the hot medium supply module needs to be equipped with an additional power source for transporting the medium, making it more environmentally friendly. The structure of the cold medium supply module and the hot medium supply module is also more streamlined.

[0142] It should be noted that the outlet ends of both the heat transfer pipe 640 and the cold transfer pipe 620 can extend to the surface of the sample stage 100, so that the heat and cold media can directly contact the microcrystalline glass substrate to be tested on the sample stage 100, thereby achieving temperature regulation of the microcrystalline glass substrate to be tested.

[0143] Alternatively, the sample stage 100 can be provided with an inner cavity (not shown in the figure). In this case, both the heat transfer medium pipe 640 and the cold transfer medium pipe 620 are connected to the inner cavity of the sample stage 100. Correspondingly, the sample stage 100 is also provided with an output pipe (not shown in the figure) for discharging the medium from the inner cavity. In this way, the temperature of the microcrystalline glass substrate under test can be adjusted by sending the heat transfer medium and cold transfer medium into the inner cavity of the sample stage 100 and then conducting heat through the sample stage 100. To improve the heat transfer efficiency, the side of the sample stage 100 used to mount the microcrystalline glass substrate under test can be made of a thermally conductive material to improve the heat transfer between the medium and the microcrystalline glass substrate under test.

[0144] The above methods can be flexibly selected according to actual needs. The specific type of medium can also be flexibly selected according to the actual situation.

[0145] Another point to note is that the number of times the impact head 140 is subjected to heating and cooling treatments on the microcrystalline glass substrate between two impacts can be adjusted by changing the ratio between the outer diameter of the outer ring 340 and the inner diameter of the reference ring 200, thereby simulating different temperature changes.

[0146] In summary, the microcrystalline glass substrate structural stability analysis system provided in this application embodiment can efficiently perform alternating heating and cooling operations on the microcrystalline glass substrate under test, which is simple and convenient, and can detect the structural stability of the microcrystalline glass substrate under test under different temperature changes.

[0147] The above description is merely a preferred embodiment of this application and is not intended to limit this application. Various modifications and variations can be made to this application by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this application should be included within the protection scope of this application.
