Abstract
Description
Technical Field
[0001] The present disclosure relates to the technical field of detection equipment, and in particular to a tensile test device and a test system. Background Art
[0002] In cover glass manufacturing and related industries, electronic universal testing machine is an important mechanical properties testing tool. It uses automatic control technology to achieve tensile, compression, bending, shear and other mechanical properties testing of various materials.
[0003] In the prior art, the viscosity test of the cover glass film 700 is usually carried out using a tensile testing machine, such as Figure 1 As shown, it includes a test platform 100, a control panel 200, a product clamping fixture 300, a film clamping fixture 400, and a screw transmission device 500. A glass sample 600 with a film 700 is placed in the product clamping fixture 300 for fixing, and then the other end of the film 700 is connected to the film clamping fixture 400, and is also effectively clamped. The screw transmission device 500 is controlled by the control panel 200 to drive the film clamping fixture 400 to move, so as to simulate the peeling or bonding process in actual use. At the same time, the control panel 200 collects the stress data acting on the film 700 in real time, and then calculates the viscosity of the film 700. However, for glass samples that are longer than the conventional design range and are relatively thin, after being clamped with the product clamping fixture 300, due to space limitations, interference with the film clamping fixture 400 may occur, and the structure that only relies on the bottom product clamping fixture 300 to fix may cause the glass sample to undergo non-negligible deformation during the force-bearing process, which will not only affect the accuracy of the film viscosity measurement results, but may even cause the glass to break in severe cases.

[0032] Example 1
[0033] In order to solve the problems existing in the prior art, the present disclosure provides a tensile test device, such as Figure 2 As shown, it includes a device body 1 and a first clamping device 2, the first clamping device 2 is arranged at the bottom of the device body 1, and is used to clamp one end of the carrier to be detected; a second clamping device 3, the second clamping device 3 is located above the first clamping device 2, and is used to clamp the other end of the carrier to be detected, and the second clamping device 3 is slidably connected to the device body 1 along a first direction; a third clamping device 4, the third clamping device 4 is slidably connected to the device body 1 along a second direction, and is used to clamp the product to be detected connected to the carrier to be detected; and a first driving device, the first driving device is arranged on the device body 1 and connected to the third clamping device 4, and is used to drive the third clamping device 4 to move along the second direction; wherein the first direction and the second direction are respectively parallel to the vertical direction, and the first direction and the second direction are non-collinearly staggered.
[0034] The device body 1 can serve as the basic support structure of the entire tensile test device, bearing the weight of all other components and devices, and ensuring the stability and rigidity of the entire system during the test. The tensile detection device provided in the embodiment of the present disclosure can drive the third clamping device 4 through the first driving device to clamp the product to be detected connected to the carrier to be detected to stretch or move along the second direction parallel to the vertical direction, so as to perform mechanical performance tests such as bonding strength, tensile strength or load capacity. Among them, the carrier to be detected can be a glass substrate, and the product to be detected can be a composite film. The viscosity of the adhesive layer of the composite film can be tested by the tensile detection device.
[0035] The tension detection device provided in the embodiment of the present disclosure clamps the two ends of the carrier to be detected by the first clamping device 2 and the second clamping device 3 respectively, so as to ensure that the carrier to be detected is stably stressed during the tension test, and avoid the problem that only one end of a long and thin carrier to be detected is fixed, resulting in deformation of the other end during the tension test, which in turn leads to inaccurate detection results and may even cause the carrier to be detected to break and injure people.
[0036] The second clamping device 3 can slide relative to the device body 1 along the first direction parallel to the vertical direction, so that the tensile test device can be used to fix the carrier to be tested of various sizes. The first direction and the second direction are arranged in a non-collinear offset manner, so that the movement direction of the third clamping device 4 and the main setting direction of the carrier to be tested form a non-collinear offset arrangement. When clamping the product to be tested, its movement trajectory and action direction can avoid the area that directly conflicts with the carrier to be tested. It can avoid that when measuring a large-sized carrier to be tested, the movement distance of the third clamping device 4 is reduced, resulting in a lack of experimental data, resulting in inaccurate test results, and may even cause the third clamping device 4 to interfere with the fixed carrier to be tested during the movement in the vertical direction, thereby causing the carrier to be tested to be damaged and injure people.
[0037] In some embodiments, the projections of the first clamping device 2 and the second clamping device 3 on the horizontal plane are staggered, and the clamping direction of the first clamping device 2 and the clamping direction of the second clamping device 3 are located in the same vertical plane; the projection of the third clamping device 4 on the horizontal plane is located outside the connecting line of the projections of the first clamping device 2 and the second clamping device 3 on the horizontal plane.
[0038] like Figure 4As shown, the second clamping device 3 is located above the first clamping device 2 in terms of spatial layout, but the positions of the two on the horizontal plane do not overlap, so that a large-sized carrier to be tested can be clamped along its diagonal direction, ensuring the stability of the carrier to be tested during the test. The clamping directions of the first clamping device 2 and the second clamping device 3 are both located in the same vertical plane, ensuring that the carrier to be tested can be arranged and stably clamped in the vertical direction, ensuring that when the carrier to be tested is subjected to tension, its force direction is consistent with the vertical direction, so that the mechanical properties of the carrier to be tested in the vertical direction can be accurately evaluated.
[0039] The projection of the third clamping device 4 on the horizontal plane is located outside the projection connection line of the first clamping device 2 and the second clamping device 3, that is, the third clamping device 4 is not directly located on the extension line of the connection line between the first clamping device 2 and the second clamping device 3, but is located in a relatively independent and sideways position. This allows the third clamping device 4 to independently clamp and apply tension to the product to be tested without interfering with the first clamping device 2 and the second clamping device 3, thereby avoiding interference between the clamping devices and causing inaccurate measurement results.
[0040] In some embodiments, the projections of the first clamping device 2 and the second clamping device 3 on the horizontal plane overlap, so that the carrier to be tested clamped by them can be set in the vertical direction and stably clamped, ensuring that the carrier to be tested will not shake or slip during the tensile test, thereby greatly improving the reliability of the test results.
[0041] In some embodiments, the device body 1 includes a bracket 101 arranged along the vertical direction, and the bracket 101 has a first surface 102 and a second surface 103 parallel to the vertical direction and connected in sequence; the third clamping device 4 is located on the first surface 102 and is slidably connected to the bracket 101, and the second clamping device 3 is located on the second surface 103 and is slidably connected to the bracket 101.
[0042] The bracket 101 serves as a stable foundation for supporting the second clamping device 3 and the third clamping device 4. The bracket 101 may be a rectangular column structure, and its length direction is arranged along the vertical direction, such as Figure 2 As shown, the first surface 102 and the second surface 103 are two adjacent surfaces that are perpendicular to each other. The two clamping devices can be installed on the two surfaces respectively by the arrangement of the first surface 102 and the second surface 103 of the bracket 101, thereby ensuring that they are sufficiently spaced in the horizontal direction. This not only avoids potential interference problems, but also helps to improve the stability and reliability of the entire device.
[0043] In some embodiments, the second clamping device 3 and the third clamping device 4 can be arranged on the same surface with intervals in the horizontal direction. By rationally planning the positions on the plane, it is ensured that the two clamping devices are sufficiently spaced in the horizontal direction to avoid interference during operation.
[0044] In some embodiments, the tensile testing device further includes a second driving device (not shown in the figure), which is disposed on the bracket 101 and connected to the second clamping device 3, and is used to drive the second clamping device 3 to move along the first direction. The height of the second clamping device 3 is precisely adjusted by the second driving device to adapt to different sizes of carriers to be tested, ensuring that the forces on both ends of the carrier to be tested are balanced and stable, thereby improving the accuracy and reliability of tensile measurement.
[0045] In some embodiments, the bracket 101 is provided with a first screw transmission mechanism 105 and a second screw transmission mechanism 106 at the positions of the first surface 102 and the second surface 103, respectively. The first screw transmission mechanism 105 is connected to the third clamping device 4, and the third clamping device 4 can move up and down along the second direction through the first screw transmission mechanism 105; the second screw transmission mechanism 106 is connected to the second clamping device 3, and the second clamping device 3 can move up and down along the first direction through the second screw transmission mechanism 106. Both the first drive device and the second drive device can be servo motors, which can drive the third clamping device 4 and the second clamping device 3 to move up and down in the vertical direction. Through the coordinated use of the drive device and the screw transmission mechanism, highly automated control can be achieved, which is conducive to improving the overall test efficiency and ensuring the reliability of the data. Among them, the first screw transmission mechanism 105, the second screw transmission mechanism 106, the first drive device, and the second drive device can all adopt existing structures, and the specific details are not repeated.
[0046] In some embodiments, the first clamping device 2 has a first clamping opening vertically upwardly arranged for accommodating one end of the carrier to be detected; the second clamping device 3 has a second clamping opening vertically downwardly arranged for accommodating the other end of the carrier to be detected; the third clamping device 4 has a third clamping opening arranged along the horizontal direction and toward the second surface 103 for accommodating one end of the product to be detected.
[0047] like Figure 3 As shown, the first clamping device 2 is provided with a first clamping opening facing upward vertically, which is used to accommodate one end of the carrier to be detected, so as to ensure that the one end of the carrier to be detected can be stably and firmly clamped from bottom to top during the test. The second clamping device 3 is also provided with a second clamping opening facing downward in the vertical direction, which is used to accommodate the other end of the carrier to be detected, so as to ensure that the other side of the carrier is firmly clamped from top to bottom.
[0048] The first clamping device 2 and the second clamping device 3 are used in conjunction to enable the carrier to be detected to be fixed in the vertical direction. The third clamping device 4 is provided with a third clamping opening facing the second surface 103 of the bracket 101 in the horizontal direction, which is used to accommodate and clamp one end of the product to be detected connected to the carrier to be detected, so as to achieve that the force direction of the product to be detected is consistent with the tensile direction of the carrier to be detected, so as to accurately simulate the force state in the actual application scenario. For example, the glass sample is fixed in the vertical direction by the first clamping device 2 and the second clamping device 3, and the film is used as the product to be detected, and one end of the film is bonded to the surface of the fixed glass sample. By utilizing the flexibility of the film material itself, the other end of the film can be extended into the third clamping opening provided by the third clamping device 4 in the horizontal direction toward the surface of the glass sample, and is effectively clamped and fixed, so as to achieve the synchronous force state of the film in the vertical direction. After the device is started, when the third clamping device 4 moves upward in the vertical direction, since both ends of the film are fixed, the direction in which it is stretched always remains consistent with the vertical direction. This can be closer to the load conditions in actual applications, making the obtained data more practical and meaningful for reference, and improving the accuracy of the test results.
[0049] The first clamping device 2, the second clamping device 3 and the third clamping device 4 disclosed in this embodiment can adopt existing mechanisms capable of clamping and fixing. For example, a mechanical self-locking clamping device can lock the clamping parts with each other by rotating, sliding, etc., so as to fix the object to be measured. The specific structure is not described in detail.
[0050] In some embodiments, the tensile testing device also includes: a connecting portion 5, the connecting portion 5 includes a first end and a second end arranged opposite to each other, the first end is slidably connected to the bracket 101 along the vertical direction, the second end is an end of the connecting portion 5 extending toward the first surface 102 and protruding from the first surface 102, the second clamping device 3 is connected to the second end; the first clamping device 2 and the third clamping device 4 are arranged on the same side of the bracket 101.
[0051] like Figure 4 As shown, the connecting portion 5 may be a plate structure, and the connecting portion 5 has a first end and a second end opposite to each other in the horizontal direction. The first end is connected to the bracket 101 by sliding in the vertical direction, so that the entire connecting portion 5 can move up and down to meet the needs of different height positions. The second clamping device 3 is fixedly connected to the second end of the connecting portion 5, so the second clamping device 3 is indirectly connected to the bracket 101 through the connecting portion 5, and its own height is adjusted as the connecting portion 5 slides in the vertical direction.
[0052] The second end of the connecting portion 5 extends toward the first surface 102 of the bracket 101 and protrudes from the first surface 102, so that the second clamping device 3 is located in the space outside the first surface 102 of the bracket 101. Thus, the second clamping device 3 and the third clamping device 4 can be located on the same side of the bracket 101, but the two are staggered in the horizontal direction, that is, they do not overlap or are not on the same vertical line, so as to avoid interference between the third clamping device 4 and the second clamping device 3. At the same time, the first clamping device 2 and the third clamping device 4 are also arranged on the same side of the bracket 101. Thus, whether it is the first clamping device 2 and the second clamping device 3 used to fix the two ends of the carrier to be tested, or the third clamping device 4 used to fix the end of the product to be tested bonded to the carrier, they can be conveniently operated simultaneously on the same side, ensuring the consistency of the direction of the tension applied to the carrier and the product, thereby effectively improving the accuracy and stability during the tension test.
[0053] In some embodiments, the device body 1 also includes a support platform 104, which is connected to the bottom of the bracket 101. The support platform 104 is provided with a slide groove (not shown in the figure) on the surface of the bracket 101, and the length direction of the slide groove is parallel to the first surface 102. The first clamping device 2 is slidably connected in the slide groove; a first limiting structure, the first limiting structure is respectively connected to the support platform 104 and the first clamping device 2, and is used to limit the displacement of the first clamping device 2 in the slide groove.
[0054] The support platform 104 is connected to the bottom of the bracket 101, and is used to support the bracket 101 and provide additional stability and load-bearing capacity. By keeping the length direction of the slide slot parallel to the first surface 102 of the bracket 101, the first clamping device 2 will always keep its motion trajectory parallel to the first surface 102 when moving in the slide slot, so as to adapt to different sizes and thicknesses of the carriers to be tested. In particular, for small and thick samples, when one end of the sample does not need to be fixed by the second clamping device 3, the first clamping device 2 can effectively clamp the carrier at different positions in the slide slot, and cooperate with the third clamping device 4 to perform accurate tensile tests.
[0055] In order to ensure that the first clamping device 2 firmly clamps the carrier to be tested at the set position without accidental movement, so as to avoid equipment damage or affect the test accuracy, the tensile test device provided in the embodiment of the present disclosure also includes a first limiting structure (not shown in the figure), which is respectively connected to the support table 104 and the first clamping device 2 through the first limiting structure, and is used to limit the position of the first clamping device 2 in the slide slot, so that the magnitude and direction of the tension applied to the carrier to be tested can be accurately controlled to improve the accuracy of the test results. The first limiting structure can adopt an existing structure, for example, an adjustable stopper is set in the slide slot, and the position of the stopper is changed by adjusting methods such as threads or positioning pins, and the first clamping device 2 stops moving when it hits the stopper, or a solenoid valve is used to control the extension length of the hydraulic cylinder or cylinder piston rod, so that the first clamping device 2 connected to the piston rod can be accurately locked at multiple preset positions. The specific structure of the first limiting structure is not limited.
[0056] In some embodiments, the tensile testing device also includes a rotating part (not shown in the figure), the third clamping device 4 is slidingly connected to the bracket 101 through the rotating part, and the third clamping device 4 is rotatably connected to the rotating part, and the direction of the third clamping opening can be rotated from a horizontal direction to a vertical downward direction through the rotating part.
[0057] The rotating part can be composed of two parts: the first part can be a guide rail or slide system slidably connected to the bracket 101, or it can be an end directly connected to the first screw transmission mechanism 105, so that the third clamping device 4 can achieve smooth and accurate up and down movement adjustment in the vertical direction; the second part can be a rotating mechanism rotatably connected to the third clamping device 4, which can adopt mechanical structures such as a rotating shaft, a hinge or a universal joint. Through this rotating mechanism, the originally horizontally arranged third clamping opening can be transformed into a vertical downward direction.
[0058] The design of the rotating part greatly improves the functionality and adaptability of the tensile test device, especially when dealing with small and thick samples, without the need to replace equipment or rearrange the experimental space. The operator only needs to adjust the rotating part to move the first clamping device 2 in the slide to just below the third clamping device 4, and then convert the originally horizontally placed third clamping opening to vertically downward to perform the test at the position corresponding to the first clamping opening. And by adding the rotation function, the tensile test device can cover more types of mechanical performance test scenarios, such as evaluating the bonding strength of materials at different angles, shear resistance, and mechanical response under various complex stress states.
[0059] In some embodiments, the tensile testing device further includes: a second limiting structure (not shown in the figure), the second limiting structure is connected to the rotating part and the third clamping device 4, and is used to limit the rotation angle of the third clamping device 4.
[0060] By setting the second limiting structure, the third clamping device 4 can be flexibly adjusted and maintain a stable angle, so that the tensile test device is suitable for more types of test requirements, and helps to provide consistent and reliable test data, reduce errors caused by changes in the clamping angle, and further improve the accuracy of the entire experimental results. The second limiting structure can adopt an existing structure, for example, it can be designed as a stop pin with elastic deformation ability. When the third clamping device 4 is rotated to a specific angle, the stop pin is embedded in a pre-designed groove under the action of a spring force to prevent further rotation, and can return to its original position after the spring force is released to release the locked state. No specific limitation is made.
[0061] In some embodiments, in order to enhance the automatic control and data acquisition capabilities of the tensile test device, an embedded control panel may be provided inside the support table 104. The control panel is electrically connected to the first drive device, and can accurately control the parameters such as the start, stop and running speed of the first drive device through a preset control program or a manual operation interface, thereby ensuring the refined management of the tension applied by the third clamping device 4 to the product to be tested. The tensile test device may also be provided with a tensile measurement sensor connected to the first drive device, which can monitor and record the change of the tensile force applied to the sample to be tested in real time. The tensile measurement sensor is communicatively connected to the control panel, so that the tensile measurement sensor can transmit the tensile information collected in real time to the control panel for display and processing. Therefore, the operator can not only intuitively observe the current tensile value through the control panel, but also set different tensile loading modes according to the actual test requirements, and judge the mechanical performance indicators of the product to be tested according to the feedback tensile data.
[0062] The tensile testing device provided in the embodiment of the present disclosure ensures that the carrier to be tested can withstand tension in a precise vertical direction through the cooperation of the first clamping device 2 and the second clamping device 3 in the vertical direction, so that the mechanical properties in the vertical direction, such as bonding strength, tensile strength, etc., can be accurately measured; the third clamping device 4 is staggered with the projections of the first clamping device 2 and the second clamping device 3 on the horizontal plane, so that it can independently clamp and load tension on the product to be tested, avoiding mutual influence of the movement of other clamping devices, and improving the accuracy of the test data. The tensile testing device of the embodiment of the present disclosure not only improves the measurement accuracy and adaptability, but also has good stability, safety and convenience, providing strong technical support for mechanical property testing.
