Description

Technical Field

[0001] The present invention relates to the technical field of microcrystalline glass detection, and in particular to a device for detecting the structural strength of a microcrystalline glass panel. Background Art

[0002] The structural strength of the glass-ceramic panel is directly related to its quality. In order to ensure that the structural strength of the glass-ceramic panel meets the use requirements, the structural strength of the glass-ceramic panel needs to be tested.

[0003] Currently, a common testing method involves using an impact mechanism to impact a glass-ceramic panel a preset number of times to assess its structural strength. This method ignores the actual use scenarios of glass-ceramic panels, and the resulting assessment results lack credibility.

[0004] In view of this, this application is hereby filed. Summary of the Invention

[0039] The beneficial effects of the technical solutions of the embodiments of the present invention include:

[0040] The microcrystalline glass panel structural strength detection device provided by the embodiment of the present invention can realize the adjustment of the impact head temperature. In this way, it is possible to simulate the use of a "hotter object" to impact the microcrystalline glass panel to be tested, as well as the use of a "colder object" to impact the microcrystalline glass panel to be tested, thereby simulating the scenario in which the microcrystalline glass panel to be tested is impacted by high-temperature objects and low-temperature objects during actual application.

DETAILED DESCRIPTION

[0063] To make the objectives, technical solutions, and advantages of the embodiments of the present invention more clear, the technical solutions of the embodiments of the present invention will be clearly and completely described below in conjunction with the accompanying drawings of the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Generally, the components of the embodiments of the present invention described and shown in the drawings herein can be arranged and designed in various different configurations.

[0064] Therefore, 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 invention as claimed, but rather merely represents selected embodiments of the present invention. All other embodiments derived by persons of ordinary skill in the art based on the embodiments of the present invention without creative effort shall fall within the scope of protection of the present invention.

[0065] It should be noted that similar reference numerals and letters denote similar items in the following drawings, and therefore, once an item is defined in one drawing, it does not require further definition or explanation in subsequent drawings.

[0066] The terms "first", "second", "third", etc. are only used for distinction and description and should not be understood as indicating or implying relative importance.

[0067] Furthermore, the terms "parallel" and "perpendicular" do not necessarily mean that the components must be absolutely parallel or perpendicular, but rather that they can be slightly tilted. For example, "parallel" simply means that the direction is more parallel than "perpendicular," not that the structure must be completely parallel, but rather that it can be slightly tilted.

[0068] In the description of the present invention, it should also be noted that, unless otherwise expressly specified or limited, the terms "disposed," "installed," and "connected" should be understood broadly. For example, they may refer to fixed connections, detachable connections, or integral connections; they may refer to direct connections, indirect connections through an intermediate medium, or internal connections between two components. Those skilled in the art will understand the specific meanings of the above terms in the present invention based on the specific circumstances.

[0069] In order to overcome the shortcomings of the existing technology, please refer to Figure 1-Figure 3 This embodiment provides a device for detecting the structural strength of a glass-ceramic panel. The device includes a driving mechanism 100 , an impact head 200 , a test bench 300 , a first container 400 , and a second container 500 .

[0070] The test bench 300 is used to install the glass-ceramic panel 2000 to be tested.

[0071] The driving mechanism 100 cooperates with the impact head 200 to enable the impact head 200 to periodically strike the glass-ceramic panel 2000 to be tested mounted on the test bench 300 , thereby using the impact head 200 to detect the structural strength of the glass-ceramic panel 2000 to be tested.

[0072] The impact head 200 has an internal flow channel 210. The first container 400 is used to contain a hot fluid medium, and the second container 500 is used to contain a cold fluid medium. The hot fluid medium and the cold fluid medium can be selected as gaseous medium or liquid medium.

[0073] The first container 400 and the second container 500 are both in communication with the internal flow channel 210 via the switch control mechanism 600 .

[0074] The switch control mechanism 600 is used to alternately connect one of the first container 400 and the second container 500 to the internal flow channel 210 .

[0075] When the switch control mechanism 600 connects 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 it impacts the micro-ceramic glass panel 2000 to be tested.

[0076] When the switch control mechanism 600 connects 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 impacting the microcrystalline glass panel 2000 to be tested.

[0077] Through the above design, the temperature of the impact head 200 can be adjusted. In this way, it is possible to simulate the use of a "hotter object" to impact the microcrystalline glass panel 2000 to be tested, as well as the use of a "colder object" to impact the microcrystalline glass panel 2000 to be tested, thereby simulating the scenario in which the microcrystalline glass panel 2000 to be tested is impacted by high-temperature objects and low-temperature objects during actual application. This can more realistically reflect the actual structural strength of the microcrystalline glass panel 2000 to be tested in actual use.

[0078] In general, 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 actual use. The test process is more consistent with the actual application scenarios, which helps to improve the credibility of the test results and make the test results more valuable for reference.

[0079] It can be understood that the impact head 200 is also provided with an outlet 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 recovered through the outlet 211, or the medium that has undergone heat exchange with the impact head 200 can be directly discarded through the outlet 211. The specific selection can be flexibly made according to actual needs.

[0080] In this embodiment, please combine Figure 4-Figure 6 The driving mechanism 100 includes: a first slide rail 110, a driver 111, a second slide rail 120, a first slider 121, a first rotating wheel 122, a third slide rail 130, a second slider 131, a second rotating wheel 132 and a driving shaft 140.

[0081] The power output shaft of the driver 111 is coaxially fixedly connected to the drive shaft 140. The driver 111 can be a motor equipped with a reducer, but is not limited thereto.

[0082] The first slide rail 110 is arranged perpendicular to the drive shaft 140. The driver 111 is slidably fitted to the first slide rail 110 along the length direction of the first slide rail 110. The driver 111 is fixedly fitted to the first slide rail 110 along the axial direction of the drive shaft 140.

[0083] The second slide rail 120 is spaced apart from the first slide rail 110 and is arranged parallel to the first slide rail 110. The first slider 121 slides and fits with the second slide rail 120 along the length of the second slide rail 120. The first slider 121 is fixedly fitted to the second slide rail 120 along the axial direction of the drive shaft 140. The first rotating wheel 122 is coaxially and fixedly connected to the drive shaft 140. The first slider 121 defines a circular through hole for mounting the first rotating wheel 122. The first rotating wheel 122 rotatably fits within the circular through hole of the first slider 121. The first rotating wheel 122 is fixedly fitted to the first slider 121 along the axial direction of the drive shaft 140.

[0084] The third slide rail 130 is spaced apart from the second slide rail 120. The third slide rail 130 is arranged perpendicular to the drive shaft 140 and the first slide rail 110. The third slide rail 130 is located on the side of the second slide rail 120 away from the first slide rail 110. Along the length direction of the third slide rail 130, the second slider 131 is slidably fitted with the third slide rail 130. Along the axial direction of the drive shaft 140, the second slider 131 is fixedly fitted with the third slide rail 130. The central axis of the second rotating wheel 132 is arranged parallel to the rotation axis of the drive shaft 140, and the second rotating wheel 132 is eccentrically fixedly connected to the drive shaft 140. The second slider 131 is provided with a circular through hole for mounting the second rotating wheel 132. The second rotating wheel 132 is rotatably fitted in the circular through hole of the second slider 131. Along the axial direction of the drive shaft 140, the second rotating wheel 132 is fixedly fitted with the second slider 131.

[0085] Correspondingly, the device for detecting the structural strength of a glass-ceramic panel further includes: a first cylinder 710 , a first piston 720 , a first stopper rod 730 , a second cylinder 810 , a second piston 820 and a second stopper rod 830 .

[0086] The first cylinder 710 is fixedly connected to one end of the second slide rail 120 and is disposed along the length direction of the second slide rail 120 . One end of the first cylinder 710 away from the first slider 121 is closed by a sealing plate.

[0087] The first piston 720 is slidably fitted in the first cylinder 710 , and the first piston 720 and the first cylinder 710 are slidably sealed.

[0088] The first plug rod 730 is fixedly connected between the first piston 720 and the first slider 121. The first plug rod 730 is arranged along the length direction of the second slide rail 120. Along the length direction of the second slide rail 120, the first plug rod 730 is slidably fitted in the second slide rail 120.

[0089] A first inlet pipe 740 and a first outlet pipe 750 are provided at one end of the first cylinder 710 away from the first slider 121. The first inlet pipe 740 is in communication with the first container 400, and the first outlet pipe 750 is used to communicate with the switch control mechanism 600. Both the first inlet pipe 740 and the first outlet pipe 750 are provided with a one-way structure. Under the action of the one-way structure, the first inlet pipe 740 can only deliver the medium into the first cylinder 710, and the first outlet pipe 750 can only discharge the medium in the first cylinder 710. The first inlet pipe 740 is in communication with the first container 400.

[0090] The second cylinder 810 is fixedly connected to one end of the third slide rail 130 and is arranged along the length direction of the third slide rail 130 . One end of the second cylinder 810 away from the second slider 131 is closed by a sealing plate.

[0091] The second piston 820 is slidably fitted in the second cylinder 810 , and the second piston 820 and the second cylinder 810 are slidably sealed.

[0092] The second plug rod 830 is fixedly connected between the second piston 820 and the second slider 131. The second plug rod 830 is arranged along the length direction of the third slide rail 130. Along the length direction of the third slide rail 130, the second plug rod 830 is slidably fitted in the third slide rail 130.

[0093] A second inlet pipe 840 and a second outlet pipe 850 are provided at the end of the second cylinder 810 away from the second slider 131. The second inlet pipe 840 communicates with the second container 500, while the second outlet pipe 850 is used to communicate with the switch control mechanism 600. Both the second inlet pipe 840 and the second outlet pipe 850 are configured with a one-way structure. Due to this one-way structure, the second inlet pipe 840 can only deliver the medium into the second cylinder 810, and the second outlet pipe 850 can only discharge the medium from the second cylinder 810. The second inlet pipe 840 communicates with the second container 500.

[0094] The one-way structure may be a one-way valve or a one-way valve, but is not limited thereto.

[0095] With the above design, when the driver 111 drives the drive shaft 140, the driver 111 reciprocates along the first slide rail 110, the first slider 121 reciprocates along the second slide rail 120, and the second slider 131 reciprocates along the third slide rail 130. In this way, the first slider 121 can drive the first piston 720, and the second slider 131 can drive the second piston 820, thereby transporting the medium in the first container 400 and the second container 500, thereby achieving temperature regulation of the impact head 200.

[0096] Furthermore, a temporary storage mechanism 900 is provided between the first outlet tube 750 and the switch control mechanism 600, and between the second outlet tube 850 and the switch control mechanism 600. Figure 7 The temporary storage mechanism 900 includes: a storage cylinder 910 , a third piston 920 and a first elastic member 930 .

[0097] Both ends of the storage barrel 910 are sealed by sealing plates. One end of the storage barrel 910 is provided with an inlet 911 and an outlet 912. Both inlet 911 and outlet 912 are provided with a one-way structure. Due to the one-way structure, the inlet 911 can only deliver the medium into the storage barrel 910, and the outlet 912 can only discharge the medium in the storage barrel 910.

[0098] The third piston 920 is slidably fitted within the storage barrel 910. The first elastic member 930 is disposed on a side of the third piston 920 away from the inlet 911 and the outlet 912. The first elastic member 930 abuts between the third piston 920 and the end of the storage barrel 910. The first elastic member 930 continuously applies a thrust to the third piston 920 toward the side where the inlet 911 and the outlet 912 are located, thereby promoting the movement of the third piston 920 toward the side where the inlet 911 and the outlet 912 are located.

[0099] The inlet 911 is used to communicate with the first outlet pipe 750 / the second outlet pipe 850, and the outlet 912 is used to communicate with the switch control mechanism 600. In this embodiment, there are two temporary storage mechanisms 900. The inlet 911 of one temporary storage mechanism 900 is connected to the first outlet pipe 750, and the outlet 912 is connected to the switch control mechanism 600. The inlet 911 of the other temporary storage mechanism 900 is connected to the second outlet pipe 850, and the outlet 912 is connected to the switch control mechanism 600.

[0100] During the process of the first cylinder 710 and the second cylinder 810 conveying the medium, the temporary storage mechanism 900 is used to temporarily store the conveyed medium, so that the switch control mechanism 600 can separately convey the medium in the two temporary storage mechanisms 900 to the impact head 200 as needed, thereby improving flexibility and reducing the requirements for the working coordination of the first cylinder 710 and the second cylinder 810.

[0101] 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.

[0102] 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 .

[0103] 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.

[0104] 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 .

[0105] 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.

[0106] 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 .

[0107] 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 .

[0108] 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.

[0109] 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. The impact terminal 240 forms a sliding seal with the wall of the mounting hole of the impact head 200. In other words, the medium in the internal flow channel 210 does not enter the mating blind hole 220, nor does it flow out of the impact head 200. A portion of the impact terminal 240 is located within the internal flow channel 210, enabling heat exchange between the impact terminal 240 and the medium in the internal flow channel 210.

[0110] The impact terminal 240 is made of a heat-conducting material.

[0111] A partition 243 is fixedly installed in the matching 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 matching blind hole 220 away from the driver 111 . The partition 243 is spaced apart from the drive shaft 140 .

[0112] A stopper 241 is fixedly connected to one 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 thrust to the impact terminal 240 to promote the impact terminal 240 to move outside the impact head 200.

[0113] Among them, the elastic force of the second elastic member 142 and the third elastic member 242 is related to the magnitude of the impact force when the impact terminal 240 hits the microcrystalline glass panel 2000 to be tested. The elastic force 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.

[0114] Please combine Figure 9 A first guide groove 250 and a second guide groove 260 are formed on the inner side wall of the blind hole 220 .

[0115] The first guide groove 250 extends spirally along the inner side wall of the matching blind hole 220 , and the second guide groove 260 extends axially along the matching blind hole 220 . The first guide groove 250 and the second guide groove 260 are sequentially distributed along the circumference of the matching blind hole 220 .

[0116] The first guide groove 250 and the second guide groove 260 are connected at one end close to the driver 111 , and the first guide groove 250 and the second guide groove 260 are connected at one end away from the driver 111 .

[0117] A mating block 143 is fixedly provided on the side wall of the end of the driving shaft 140, and the mating block 143 is used to slide and fit in the first guide groove 250 and the second guide groove 260, so that when the driving shaft 140 rotates, the impact head 200 can reciprocate along the axial direction of the driving shaft 140, so that the impact terminal 240 can periodically impact the microcrystalline glass panel 2000 to be tested installed on the test bench 300.

[0118] In this embodiment, a third guide groove 270 is further provided between the first guide groove 250 and the second guide groove 260. The third guide groove 270 extends along the circumference of the mating blind hole 220. The third guide groove 270 is located at one end of the first guide groove 250 and the second guide groove 260 away from the driver 111. The end of the first guide groove 250 away from the driver 111 and the end of the second guide groove 260 away from the driver 111 are respectively connected to the two ends of the third guide groove 270.

[0119] The first guide groove 250 , the third guide groove 270 and the second guide groove 260 together constitute a set of guide groove bodies.

[0120] There are at least two groups of guide grooves, which are sequentially arranged along the circumference of the matching blind holes 220. In this embodiment, there are two groups of guide grooves.

[0121] Specifically, one end of the first guide groove 250 of one group of guide grooves close to the driver 111 is connected to the other end of the second guide groove 260 of the other group of guide grooves close to the driver 111 .

[0122] For all guide grooves, the third guide groove 270 of at least one is located on the side of the third guide groove 270 of the other that is away from the driver 111. In the two groups of guide grooves in this embodiment, the third guide grooves 270 of one group are located on the side of the third guide grooves 270 of the other group that is away from the driver 111. In other words, the distance from the third guide grooves 270 of one group to the driver 111 is greater than the distance from the third guide grooves 270 of the other group to the driver 111.

[0123] In this embodiment, along the circumference of the drive shaft 140 , the central angles corresponding to the spans of the first guide groove 250 and the third guide groove 270 are the same.

[0124] Furthermore, the switch control mechanism 600 includes: a reference member 610 , a matching arm 620 , a first pipe 630 , a second pipe 640 and a third pipe 650 .

[0125] The reference member 610 is fixedly mounted on the limiting frame 230 . The reference member 610 is annular and is disposed outside the driving shaft 140 . The driving shaft 140 can rotate relative to the reference member 610 .

[0126] The engagement arm 620 is fixedly connected to the impact head 200 . The engagement arm 620 is disposed along the axial direction of the driving shaft 140 . The engagement arm 620 is in contact with the reference piece 610 and is slidably engaged with the reference piece 610 .

[0127] The first pipe 630 and the second pipe 640 are embedded in the reference part 610, and one end of the first pipe 630 and the second pipe 640 both penetrate the fitting surface of the reference part 610 and the matching arm 620, and the other end of the first pipe 630 and the second pipe 640 extend outside the reference part 610.

[0128] At the mating surface between the reference member 610 and the engagement arm 620 , the ends of the first pipe 630 and the second pipe 640 are spaced apart along the axial direction of the drive shaft 140 .

[0129] The end of the first pipe 630 away from the bonding surface is used to communicate with the outlet 912 of the temporary storage mechanism 900 connected to the first container 400, and the end of the second pipe 640 away from the bonding surface is used to communicate with the outlet 912 of the temporary storage mechanism 900 connected to the second container 500.

[0130] The third conduit 650 is mounted on the engagement arm 620 , and the end of the third conduit 650 extends through the mating surface between the engagement arm 620 and the reference member 610 . The end of the third conduit 650 away from the mating surface is in communication with the internal flow channel 210 .

[0131] The working principle of the microcrystalline glass panel structure strength detection device is as follows: when the driver 111 drives the driving shaft 140 to rotate, for example, the driving mechanism 100 is in Figure 4-Figure 6 The state shown is the starting state, and the rotation direction of the drive shaft 140 is Figure 4-Figure 6 The direction of rotation is clockwise from the viewing angle shown. Figure 4-Figure 6 In the state shown, the mating block 143 of the drive shaft 140 is located Figure 9The P1 position in FIG. 1 indicates that the mating block 143 is located in the guide groove body corresponding to the third guide groove 270 closer to the driver 111, and is located at the end of the first guide groove 250 of the guide groove body closer to the driver 111. At this time, the third pipe 650 is located on the side of the first pipe 630 and the second pipe 640 away from the driver 111, and the mating arm 620 closes the end of the first pipe 630 and the second pipe 640 located on the fitting surface. In this state, the second cylinder 810 of the temporary storage mechanism 900 connected to the second container 500 stores the cold medium corresponding to the second container 500, and the amount of stored cold medium is the same as the amount absorbed / released once by the second cylinder 810. The temporary storage mechanism 900 connected to the first container 400 is empty and does not store any medium.

[0132] As the drive shaft 140 continues to rotate, the mating block 143 of the drive shaft 140 moves along the first guide groove 250 and moves toward the end of the first guide groove 250 away from the driver 111. Therefore, under the action of the mating block 143 and the first guide groove 250, the impact head 200 moves along the axial direction of the drive shaft 140 toward the side where the driver 111 is located, and the second elastic member 142 is compressed.

[0133] During this process, due to the cooperation between the second rotating wheel 132 and the driving shaft 140, the driving shaft 140 will move along the length direction of the first slide rail 110, and the second slider 131 will also move along the third slide rail 130. Figure 4-Figure 6 Taking the perspective shown as an example, the drive shaft 140 moves to the right, thereby driving the driver 111 to move to the right along the first slide rail 110, driving the first rotating wheel 122 to move to the right, driving the first slider 121 to move to the right along the second slide rail 120, and driving the second rotating wheel 132 to move to the right, driving 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 draw the hot medium in the first container 400 into the first cylinder 710, and the second slider 131 can pull the second piston 820 to draw the cold medium in the second container 500 into the second cylinder 810.

[0134] When the drive shaft 140 rotates 90°, the drive mechanism 100 enters Figure 10-12 At this time, the first slider 121 moves to the rightmost dead point, and the amount of medium absorbed in the first cylinder 710 reaches the maximum. The second slider 131 moves to the middle of the sliding stroke. The matching block 143 of the drive shaft 140 is located at Figure 9At position P2, the third pipe 650 moves to the second pipe 640 and connects to it. The end of the third pipe 650 located on the contact surface is sealed by the mating arm 620. In this state, the temporary storage mechanism 900, which is connected to the second container 500, begins to supply 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, cooling the impact terminal 240.

[0135] As the drive shaft 140 continues to rotate, the engaging block 143 moves along the third guide groove 270 toward the second guide groove 260, while the axial position of the impact head 200 on the drive shaft 140 remains unchanged. The second slider 131 further moves upward along the third slide rail 130, and the drive shaft 140 drives the first slider 121 and the driver 111 to move leftward. During this process, the temporary storage mechanism 900 connected to the second container 500 continues to transport cold medium to the third pipeline 650 through the second pipe 640. The second piston 820 continues to draw cold medium from the second container 500 into the second cylinder 810, while the first piston 720 begins to push the hot medium in the first cylinder 710 into the temporary storage mechanism 900 connected to it.

[0136] When the drive shaft 140 rotates another 90°, the drive mechanism 100 enters Figure 13-15 At this time, the second slider 131 moves to the uppermost dead point, and the absorption amount of the medium in the second cylinder 810 reaches the maximum. The first slider 121 moves to the middle of the sliding stroke, and a part of the heat medium in the first cylinder 710 is pushed into the temporary storage mechanism 900 connected thereto. In this state, the matching block 143 is located Figure 9 The P3 position in .

[0137] Among them, the temporary storage mechanism 900 connected to the second container 500 needs to discharge all the cold medium in the second cylinder 810 before the matching block 143 reaches P3. This can be achieved by adjusting the elastic force of the first elastic member 930, the inner diameter of the guide 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, and the inner diameter of the discharge port 211, and is not limited to this.

[0138] That is to say, when the matching block 143 reaches P3, the cold medium in the temporary storage mechanism 900 connected to the second container 500 has been completely discharged, and the impact terminal 240 is fully cooled by the cold medium. At the same time, since the matching block 143 can move along the second guide groove 260, under the elastic force of the second elastic member 142, the impact head 200 is reset along the axial movement of the drive shaft 140, and 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 matching block 143 moves to Figure 9 The P4 position in .

[0139] As the drive shaft 140 continues to rotate, the mating block 143 enters the first guide groove 250 of another set of guide groove bodies and moves along the first guide 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 connected thereto, and the second slider 131 begins to push the cold medium in the second cylinder 810 into the temporary storage mechanism 900 connected thereto.

[0140] When the drive shaft 140 rotates another 90°, the drive mechanism 100 enters Figure 16-18 At this time, the first slider 121 pushes all the hot medium in the first cylinder 710 into the temporary storage mechanism 900 connected thereto, and the second slider 131 pushes part of the cold medium in the second cylinder 810 into the temporary storage mechanism 900 connected thereto, and the matching block 143 is located at Figure 9 At position P5, the third pipe 650 moves to the first pipe 630 and connects with it, while the second pipe 640 is sealed by the engagement arm 620. Although the third pipe 650 briefly connects with the second pipe 640 before reaching the teeth of the first pipe 630, this brief connection prevents significant cold medium from entering the third pipe, resulting in no significant impact. At this point, the impact head 200 resumes its axial movement along the driver 111 and away from the test bench 300.

[0141] When the matching block 143 reaches Figure 9 After reaching the P5 position in the middle, the temporary storage mechanism 900 connected to the first container 400 starts to transport the heat medium to the third pipe 650 through the first pipe 630 , and the heat medium enters the internal flow channel 210 to heat the impact terminal 240 .

[0142] When the driving shaft 140 continues to rotate, the first slider 121 starts to use the first piston 720 to suck the hot medium in the first container 400 into the first cylinder 710 again, and the second slider 131 continues to push the cold medium in the second cylinder 810 into the temporary storage mechanism 900 connected thereto.

[0143] When the drive shaft 140 rotates another 90°, the drive mechanism 100 returns to Figure 4-Figure 6 As shown, the mating block 143 reaches Figure 9 The temporary storage mechanism 900 connected to the first container 400 needs to discharge all the heat medium in the first cylinder 710 before the matching block 143 reaches P6.

[0144] The matching block 143 can return to the P1 position along the second guide groove 260 , and the impact head 200 can once again carry the impact terminal 240 to impact the micro-ceramic glass panel 2000 to be tested installed on the test bench 300 , thereby simulating a high-temperature impact.

[0145] Based on the above process, the drive shaft 140 continues to rotate to realize circulation and achieve alternating hot and cold impact.

[0146] Furthermore, the test table 300 is slidably engaged with the fourth slide rail 310, which is arranged parallel to the second slide rail 120. The limit frame 230 is fixedly connected to the test table 300. Through this design, during the test process, the limit frame 230 and the test table 300 will move with the movement of the drive shaft 140, ensuring that the impact terminal 240 continuously performs the impact test on the same position of the micro-ceramic glass panel 2000 to be tested.

[0147] To sum up, the microcrystalline glass panel structural strength detection device provided by the embodiment of the present invention can perform targeted testing on the structural strength of the microcrystalline glass panel according to the application scenarios in actual use. The test process is more consistent with the actual application scenarios, which helps to improve the credibility of the test results and make the test results more valuable for reference.

Those skilled in the art will readily appreciate that various modifications and variations of the present invention are possible.
