DETAILED DESCRIPTION

[0041] In order to make the purpose, 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 in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are 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 here can be arranged and designed in various different configurations.

[0042] 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 claimed for protection, but merely represents selected embodiments of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0043] 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, further definition and explanation thereof is not required in subsequent drawings.

[0044] The terms “first”, “second”, etc. are only used for distinguishing descriptions and should not be understood as indicating or implying relative importance.

[0045] In addition, the terms "parallel", "vertical", etc. do not mean that the components must be absolutely parallel or vertical, but can be slightly tilted. For example, "parallel" only means that its direction is more parallel than "vertical", and does not mean that the structure must be completely parallel, but can be slightly tilted.

[0046] In the description of the present invention, it is also necessary to explain that, unless otherwise clearly specified and limited, the terms "setting", "installation" and "connection" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a direct connection, or an indirect connection through an intermediate medium, or it can be a communication between the two elements. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0047] The inventor of the present application has found that in the traditional testing of the mechanical impact resistance of microcrystalline glass panels, an impact device is usually used to directly impact the microcrystalline glass panel for a preset number of times to determine whether the mechanical impact resistance of the microcrystalline glass panel meets the requirements. However, when the microcrystalline glass panel is used in an induction cooker, this testing method is greatly different from the actual use of the induction cooker, and its test results are easily different from the actual use, which directly reduces the reference value of the test results.

[0048] Among them, the mechanical impact faced by the induction cooker is not a simple impact in many cases. The induction cooker is used for cooking during use. For example, when the user is cooking, if the user accidentally uses a large force to cook, it will cause the spatula to hit the wok with a large initial force, and the mechanical impact is transmitted to the microcrystalline glass panel through the pot body. What is special is that when the spatula hits the pot body, the user can receive somatosensory feedback of the impact force. When the user realizes that the force is too large (especially users with rich cooking experience), the user will subconsciously reduce the force. In other words, during the cooking process, even if the microcrystalline glass panel is subjected to an initial strong impact, after being subjected to the force, the impact strength changes from strong to weak during the entire impact process.

[0049] In addition, during the cooking process, the spatula will not separate directly from the pot body after hitting the pot body, but will stir-fry along the pot body. That is, after the spatula hits the pot body, it will move a certain distance along the pot body with a certain force.

[0050] These are the differences between the use of induction cookers and traditional mechanical impact tests. These will cause the traditional testing methods to be unable to accurately reflect actual usage, resulting in reduced reference value of the test results.

[0051] In the actual production process, in order to ensure that the micro-ceramic glass panels can meet the use requirements of the induction cooker, when the traditional mechanical impact test is adopted, it is usually tested with a higher standard. Although this can ensure that qualified micro-ceramic glass panels can meet the use requirements of the induction cooker, the improvement of the standard will lead to an erroneous increase in the failure rate of micro-ceramic glass panels. There is a situation where micro-ceramic glass panels that actually meet the use requirements of the induction cooker are judged as unqualified, which will cause waste of micro-ceramic glass panels.

[0052] To overcome the above defects, please refer to Figure 1-Figure 4 , this embodiment provides a system for testing the mechanical impact resistance of a microcrystalline glass panel.

[0053] The microcrystalline glass panel mechanical impact resistance testing system comprises: a base 100 , an impact head 200 , a connecting member 300 , an elastic member 400 and a first piston 500 .

[0054] The base body 100 is provided with a medium cavity 110 , an impact cavity 120 and a storage cavity 130 .

[0055] The impact cavity 120 is connected to the medium cavity 110. In this embodiment, the impact cavity 120 is coaxially arranged with the medium cavity 110. The impact cavity 120 penetrates to the surface of the substrate 100. Both the medium cavity 110 and the impact cavity 120 are spaced apart from the receiving cavity 130.

[0056] The first piston 500 is slidably fitted in the medium chamber 110 and is slidably sealed with the inner wall of the medium chamber 110. The connecting member 300 is slidably fitted in the impact chamber 120 and is slidably sealed with the inner wall of the impact chamber 120.

[0057] The side wall of the impact chamber 120 is provided with a first flow channel 121 and a second flow channel 122 . The first flow channel 121 is communicated with the medium chamber 110 , and the second flow channel 122 is communicated with the receiving chamber 130 .

[0058] The connecting member 300 is provided with a connecting flow channel 310. The connecting member 300 has a first sliding point and a second sliding point.

[0059] When the connecting member 300 is located at the first sliding point, the first flow channel 121 and the second flow channel 122 are both offset from the connecting flow channel 310 , and the connection between the first flow channel 121 and the second flow channel 122 is blocked by the connecting member 300 .

[0060] When the connecting member 300 is located at the second sliding point, both the first flow channel 121 and the second flow channel 122 are connected to the connecting flow channel 310 , and the first flow channel 121 and the second flow channel 122 are connected through the connecting member 300 .

[0061] The medium chamber 110 is used to contain a liquid medium.

[0062] The elastic member 400 abuts between the first piston 500 and the connecting member 300 , and the impact chamber 120 is provided with an anti-slip mechanism 123 for preventing the connecting member 300 from slipping out.

[0063] In the initial state, the connecting member 300 is located at the first sliding point, and the connecting channel 310 is located on the side of the first channel 121 and the second channel 122 away from the medium cavity 110. The impact head 200 is installed at one end of the connecting member 300 away from the medium cavity 110. Under the elastic force of the elastic member 400, the impact head 200 fully extends out of the base 100.

[0064] During the test, the driving mechanism can be used to drive the base 100, so that the impact head 200 can mechanically impact the surface of the microcrystalline glass panel to be tested. After the impact head 200 contacts the surface of the microcrystalline glass panel to be tested, as the base 100 further approaches the microcrystalline glass panel to be tested, the impact head 200 will be pushed into the impact cavity 120 by the microcrystalline glass panel to be tested. Since the medium cavity 110 contains a liquid medium, the first piston 500 will not move, and the elastic member 400 will be elastically compressed. In this process, the impact force gradually increases, and the connecting member 300 is pushed from the first sliding point to the second sliding point.

[0065] As the substrate 100 continues to approach the microcrystalline glass panel to be tested, when the connector 300 is pushed to the second sliding point, the first flow channel 121 and the second flow channel 122 are connected through the connecting flow channel 310 of the connector 300. Figure 5 As shown, at this time, the liquid medium in the medium cavity 110 can enter the receiving cavity 130 through the first flow channel 121, the connecting flow channel 310 and the second flow channel 122. In this way, the first piston 500 can move along the medium cavity 110 toward the end away from the impact cavity 120, so that the first piston 500 can "retreat" relative to the microcrystalline glass panel to be tested. In this process, the impact force on the microcrystalline glass panel to be tested can be reduced to a certain extent, realizing the simulation of "retracting force", such as Figure 6 shown.

[0066] When the liquid medium cannot further enter the storage chamber 130 (for example, the storage chamber 130 is already filled), the first piston 500 cannot continue to "retreat". At this time, the base 100 can continue to be driven to translate relative to the surface of the microcrystalline glass panel to be tested according to the force after "retraction", thereby simulating the frying action.

[0067] Through the above design, the microcrystalline glass panel anti-mechanical impact performance testing system can more accurately restore the impact conditions of the microcrystalline glass panel to be tested during the use of the induction cooker, thereby ensuring the credibility of the test results.

[0068] On this basis, when the driving mechanism is used to drive the base 100 to make the impact head 200 impact the microcrystalline glass panel to be tested, even if the driving mechanism accidentally controls the impact head 200 to impact the microcrystalline glass panel to be tested with a force greater than the preset force, during the impact process, when the connecting member 300 switches to the second sliding point, the impact force can be reduced through the "force reduction" process to avoid direct damage to the microcrystalline glass panel to be tested due to excessive impact force, thereby improving the protection effect of the detection process on the microcrystalline glass panel to be tested and avoiding accidental damage to the detection object.

[0069] In general, the microcrystalline glass panel mechanical impact resistance test system provided in this embodiment can more accurately simulate the mechanical impact of the microcrystalline glass panel of the induction cooker product during actual use, and facilitates the detection of the specific application effect of the microcrystalline glass panel in the induction cooker product that is more in line with the actual use, so as to more accurately judge whether the microcrystalline glass panel meets the application standards in the induction cooker product, and more accurately screen the microcrystalline glass panel suitable for the induction cooker product while ensuring the quality requirements of the microcrystalline glass panel. In this way, the detection accuracy of the microcrystalline glass panel to be tested can be effectively improved, so that the actual use performance of the microcrystalline glass panel to be tested can be more accurately evaluated, so as to accurately match the use of the microcrystalline glass panel to be tested, and avoid unnecessary waste of the microcrystalline glass panel to be tested.

[0070] It can be understood that the microcrystalline glass panel anti-mechanical impact performance test system can also be provided with an installation platform according to actual needs, and the installation platform is used to install the microcrystalline glass panel to be tested. The driving mechanism can adopt a mechanical arm, but is not limited thereto. In order to facilitate the detection, other components can also be provided according to actual needs, which will not be repeated here.

[0071] In this embodiment, the cross-sections of the medium cavity 110 , the impact cavity 120 and the storage cavity 130 are all circular. The connecting member 300 is cylindrical, and the outer wall of the connecting member 300 is in contact with the inner wall of the impact cavity 120 .

[0072] The elastic member 400 may be a spring, but is not limited thereto.

[0073] The impact chamber 120 is provided with a balance hole 125 communicating with the external atmosphere, so as to balance the air pressure at the elastic member 400 in the impact chamber 120 during the impact process.

[0074] Furthermore, an adjustment cylinder 320 , an adjustment rod 330 and a rotating member 340 are further provided at one end of the connecting member 300 close to the medium cavity 110 .

[0075] The rotating member 340 is located on a side of the adjusting cylinder 320 close to the medium cavity 110 . The adjusting cylinder 320 has an internal thread, and the adjusting rod 330 has an external thread. The adjusting rod 330 and the adjusting cylinder 320 are threadedly matched. The rotating member 340 is fixedly connected to the adjusting rod 330 .

[0076] The elastic member 400 is in contact with the first piston 500 and the rotating member 340. The regulating cylinder 320 is in contact with one end of the connecting member 300 close to the medium cavity 110.

[0077] With this design, the distance between the rotating member 340 and the first piston 500 in the initial state can be adjusted by rotating the rotating member 340, thereby changing the elastic force of the elastic member 400 in the initial state, so that the impact force of the impact head 200 when impacting the microcrystalline glass panel to be tested can be regulated.

[0078] Optionally, abutment member 350 may be further provided on one side of the rotating member 340 close to the elastic member 400; the abutment member 350 is slidably matched with the impact chamber 120 along the axial direction of the impact chamber 120; and the abutment member 350 is fixedly matched with the impact chamber 120 along the circumferential direction of the impact chamber 120. The rotating member 340 is rotatably matched with the abutment member 350, and a driver may be built in the abutment member 350 to drive the rotating member 340 to adjust the impact force. The elastic member 400 abuts between the abutment member 350 and the first piston 500.

[0079] In this embodiment, a stopper 111 is provided at one end of the medium cavity 110 close to the impact cavity 120 to prevent the first piston 500 from leaving the medium cavity 110. In the initial state, the first piston 500 is attached to the stopper 111. The liquid medium is located on the side of the first piston 500 away from the impact cavity 120.

[0080] The inner wall of the impact chamber 120 at one end close to the medium chamber 110 is also provided with a clearance groove 124, which continuously extends in a ring shape along the circumference of the impact chamber 120, and extends in the axial direction of the impact chamber 120. The anti-slipping mechanism 123 is an anti-slipping ring, which is arranged around one end of the adjustment cylinder 320 close to the rotating member 340, and the outer diameter of the anti-slipping mechanism 123 is adapted to the clearance groove 124, and the anti-slipping mechanism 123 is slidably fitted in the clearance groove 124. The adjustment cylinder 320 is fixedly connected to the connecting member 300, and during the detection process, the connecting member 300 will never completely enter the clearance groove 124. The impact head 200 is detachably connected to the connection head, so that the impact head 200 of a required type can be replaced as needed.

[0081] Furthermore, a second piston 131 and a control cylinder 132 are also disposed in the receiving chamber 130 .

[0082] The second piston 131 is slidably fitted in the receiving chamber 130 and is slidably sealed with the inner wall of the receiving chamber 130 .

[0083] The second flow channel 122 is located at one end surface of the receiving chamber 130. An extension hole 133 is provided at one end of the receiving chamber 130 away from the second flow channel 122, and the extension hole 133 penetrates to the surface of the base 100. The control cylinder 132 is located at a side of the second piston 131 away from the second flow channel 122. The extension hole 133 has an internal thread, and the control cylinder 132 has an external thread. The control cylinder 132 is threadedly matched with the extension hole 133 and extends into the receiving chamber 130.

[0084] With this design, the length of the control cylinder 132 extending into the receiving chamber 130 can be changed by rotating the control cylinder 132, thereby adjusting the space in which the second piston 131 can slide along the receiving chamber 130. In this way, when the liquid medium enters the receiving chamber 130, the second piston 131 can at most move to abut against the control cylinder 132. When the second piston 131 abuts against the control cylinder 132, the liquid medium can no longer enter the receiving chamber 130 from the medium chamber 110, and the "force collection" end point is reached.

[0085] Furthermore, the base body 100 is further provided with an annular inner cavity 140 , which is arranged around the impact cavity 120 and spaced apart from the impact cavity 120 . Specifically, the annular inner cavity 140 is arranged outside the receiving groove, and the annular inner cavity 140 is arranged corresponding to the elastic member 400 .

[0086] The inner wall of the impact cavity 120 is provided with a connecting gap connected to the give way groove 124 of the annular inner cavity 140. The connecting gap extends along the length direction of the annular inner cavity 140. An isolating member 141 is accommodated in the connecting gap. The isolating member 141 closes the connecting gap. The isolating member 141 is made of heat conductive material.

[0087] The end surface of the receiving chamber 130 having the second flow channel 122 is also provided with a third flow channel 134, the third flow channel 134 is connected to the end of the annular inner chamber 140 close to the impact head 200, and a one-way mechanism 135 is provided in the third flow channel 134 to prevent the liquid medium from flowing back to the receiving chamber 130. The one-way mechanism 135 can be a one-way valve, but is not limited thereto.

[0088] The inner wall of the annular inner cavity 140 is also provided with a reflux hole 142, which is located at one end of the annular inner cavity 140 away from the impact head 200 and communicates with the medium cavity 110 through a reflux channel 143. The first flow channel 121 and the reflux channel 143 are both communicated with one end of the medium cavity 110 away from the impact cavity 120.

[0089] The microcrystalline glass panel anti-mechanical impact performance testing system further includes: a reflux push rod 600. The outer diameter of the reflux push rod 600 is smaller than the inner diameter of the control cylinder 132.

[0090] The reflux push rod 600 is used to pass through the extension hole 133 and the control cylinder 132 to push the second piston 131 so as to send the liquid medium in the receiving chamber 130 into the annular inner chamber 140 .

[0091] Among them, the liquid medium is a heat conducting medium.

[0092] After an impact is completed, the driving mechanism drives the base 100 away from the microcrystalline glass panel to be tested, and the impact head 200 is separated from the microcrystalline glass panel to be tested. Under the action of the elastic member 400, the impact head 200 re-extends out of the base 100, and the anti-slip mechanism 123 abuts against the end of the yielding groove 124 close to the impact head 200. At this time, the connecting member 300 is in the first sliding point, and the first flow channel 121 and the second flow channel 122 are not connected. The reflux push rod 600 can be used to push the second piston 131 to return the second piston 131 to the end of the storage chamber 130 away from the extension hole 133 to achieve reset. At the same time, the liquid medium in the storage chamber 130 is pushed into the annular inner cavity 140 by the third flow channel 134, and the excess liquid medium returns to the medium cavity 110 through the reflux hole 142 and the reflux channel 143 to achieve the return of the liquid medium.

[0093] Through this design, during the repeated impact process, the liquid medium continuously enters the storage chamber 130 from the medium chamber 110, and then returns to the medium chamber 110 from the storage chamber 130 through the annular inner chamber 140, thereby realizing the internal circulation of the liquid medium. In this process, the liquid medium in the annular inner chamber 140 can absorb the heat in the give way groove 124 through the isolation member 141, thereby realizing the cooling of the elastic member 400, so that the elastic member 400 is always kept in a suitable temperature range, ensuring the stability of the elastic coefficient of the elastic member 400, and facilitating the precise control of the impact force.

[0094] Optionally, along the axial direction of the reflux push rod 600, the reflux push rod 600 is slidably matched with the control cylinder 132. Along the circumferential direction of the reflux push rod 600, the reflux push rod 600 is fixedly matched with the control cylinder 132. The position of the control cylinder 132 can be adjusted by driving the reflux push rod 600 to rotate, thereby adjusting the amount of liquid medium that can be contained in the storage chamber 130, so as to achieve the purpose of changing the amplitude of the "retracting force".

[0095] Further, the reflux channel 143 includes: a reflux pipe. The reflux pipe is located outside the base 100. One end of the reflux pipe is connected to the reflux hole 142, and the other end is connected to the medium cavity 110. The reflux pipe is made of a heat-conducting material. In this way, when the driving mechanism drives the base 100 to move, there will be airflow around the reflux channel 143 to achieve cooling of the liquid medium in the reflux channel 143, thereby ensuring the cooling effect of the liquid medium on the elastic member 400.

[0096] Furthermore, the balancing hole 125 is opened on the side wall of the impact cavity 120 at one end close to the medium cavity 110 , and the balancing hole 125 penetrates to the surface of the substrate 100 .

[0097] The impact chamber 120 is located at the bottom of the base 100, that is, the impact chamber 120 is arranged downward. The side of the connecting member 300 close to the medium chamber 110 contains a liquid heat-conducting medium. Specifically, the abutment member 350 is slidably fitted in the clearance groove 124 and is slidably sealed with the inner wall of the clearance groove 124. The liquid heat-conducting medium is located on the side of the abutment member 350 away from the rotating member 340. During the impact process, the liquid level of the liquid heat-conducting medium is always located below the balance hole 125, that is, when the abutment member 350 moves upward to the closest distance to the first piston 500, after the liquid level of the liquid heat-conducting medium stabilizes, the liquid level of the liquid heat-conducting medium is still located below the balance hole 125.

[0098] With this design, during the impact process, the abutment member 350 can push / lift the liquid heat-conducting medium upward, so that the liquid heat-conducting medium can better absorb the heat of the elastic member 400 near the end of the first piston 500, thereby improving the cooling effect on the elastic member 400. The heat absorbed by the liquid heat-conducting medium is transferred by the isolation member 141 to the liquid medium in the annular inner cavity 140 to achieve heat dissipation.

[0099] In order to prevent the liquid heat-conducting medium from being accidentally thrown out of the balance hole 125 when the abutment member 350 pushes up / lifts the liquid heat-conducting medium, a ventilation mechanism 700 is disposed in the balance hole 125. Figure 7 shown.

[0100] The ventilation mechanism 700 includes a ventilation cylinder 710 , a first blocking bar 720 , a second blocking bar 730 , a sealing plate 740 , a connecting column 750 and a reference plate 760 .

[0101] The cross section of the inner space of the vent cylinder 710 is rectangular.

[0102] The first stopper 720 is disposed on the top wall of the ventilator 710 and extends along the width direction of the ventilator 710, and the second stopper 730 is disposed on the bottom wall of the ventilator 710 and extends along the width direction of the ventilator 710. The lengths of the first stopper 720 and the second stopper 730 are both the same as the width of the ventilator 710. Along the axial direction of the ventilator 710, the second stopper 730 is located on a side of the first stopper 720 away from the impact chamber 120.

[0103] The width of the sealing plate 740 is the same as the width of the ventilator 710. The sealing plate 740 is arranged between the first baffle bar 720 and the second baffle bar 730. The top end of the sealing plate 740 is in contact with the first baffle bar 720 (the side of the top end of the sealing plate 740 away from the second baffle bar 730 is in contact with the side of the first baffle bar 720 close to the second baffle bar 730), and the bottom end of the sealing plate 740 is in contact with the second baffle bar 730 (the side of the bottom end of the sealing plate 740 away from the first baffle bar 720 is in contact with the side of the second baffle bar 730 close to the first baffle bar 720).

[0104] The reference plate 760 is arranged perpendicular to the axial direction of the ventilator 710 and is located on the side of the second stop bar 730 away from the first stop bar 720. The reference plate 760 is connected to the top wall / bottom wall of the ventilator 710 by an elastic glue point 770. The reference plate 760 is connected to the sealing plate 740 by a connecting column 750. The connecting column 750 is made of elastic material. In a natural state, the reference plate 760 is arranged perpendicular to the axis of the ventilator 710. Since the reference plate 760 is connected to the ventilator 710 by the elastic glue point 770, the reference plate 760 can be deflected relative to the ventilator 710.

[0105] When the abutment member 350 moves toward the first piston 500, the air in the impact chamber 120 is discharged through the ventilation mechanism 700. In this process, the air pushes the sealing plate 740 open, and the bottom end of the sealing plate 740 is blocked by the second stopper 730. The top end of the sealing plate 740 is separated from the first sealing bar and opened. Under the action of the connecting column 750, the reference plate 760 is deflected to the side away from the second stopper 730. Figure 8 In this way, the upwardly moving liquid heat-conducting medium can be effectively prevented from flowing out of the vent cylinder 710 .

[0106] When the abutment member 350 moves toward the side where the impact head 200 is located, the external air enters the impact chamber 120 through the ventilation mechanism 700. In this process, the air pushes the sealing plate 740 away, the top of the sealing plate 740 is blocked by the first stop bar 720, and the bottom of the sealing plate 740 is separated from the second sealing bar and opened. Under the action of the connecting column 750, the reference plate 760 deflects toward the side close to the second stop bar 730. Fig. 9 In this way, the liquid heat-conducting medium dripping from top to bottom can be effectively prevented from flowing out of the vent cylinder 710 .

[0107] This can effectively reduce the loss of liquid heat transfer medium.

[0108] Optionally, the connecting flow channel 310 extends along the axial direction of the impact chamber 120 .
