Description

Technical Field

[0001] The utility model relates to the technical field of testing equipment, in particular to a tensile testing machine for detecting the tensile strength of adhesive glue. Background Technique

[0002] A tensile testing machine is a testing device used to measure the tensile strength of an object. After the production of photovoltaic edge sealant, through the test of the tensile testing machine, the tensile strength of the tape can be evaluated to ensure that it meets the product quality standards. The application of this device not only improves the production quality of photovoltaic edge sealant, but also reduces the product rejection rate and production cost.

[0003] When conducting a tensile test, certain operation steps need to be followed. First, prepare the tensile testing machine and the photovoltaic edge sealant sample to be tested. Then, fix the sample on the fixture of the tensile testing machine and set appropriate test parameters, such as tensile speed, test temperature, etc. Next, start the tensile testing machine for testing, observe the stretching process of the sample, and record relevant data.

[0004] However, when clamping the existing photovoltaic edge sealant, the pressure of the fixture will cause a weak area to form at the part where the test specimen contacts the fixture. During the tensile test, the specimen breaks at the weak area, resulting in the defect of inaccurate test results.

[0005] Based on this, the utility model designs a tensile testing machine for detecting the tensile strength of adhesive glue to solve the above problems. Content of the Utility Model

[0006] The purpose of the utility model is to provide a tensile testing machine for detecting the tensile strength of adhesive glue to solve the above technical problems.

[0007] To achieve the above purpose, the utility model provides the following technical solutions: including an installation platform, a clamping device, and a sample preparation device; a fixing frame is fixedly arranged on the installation platform, and an installation frame is slidably arranged on the fixing frame; two clamping devices are provided, and the two clamping devices are respectively fixedly arranged on the installation platform and the installation frame; the sample preparation device is fixedly arranged on the two clamping devices; the sample preparation device includes an upper module, a separation block, and a lower module. An injection hole is opened on the upper module, and a sealing block is inserted on the injection hole; the upper module and the lower module are respectively fixedly arranged on the two clamping devices, and two separation blocks are provided. The two separation blocks are respectively inserted on the upper module and the lower module; when the two separation blocks are in contact with each other, the upper module, the two separation blocks, and the lower module form an inner cavity, and the injection hole is communicated with the inner cavity.

[0008] By adopting the above technical solution, the sample preparation device for making samples is installed on the clamping device, so that when the clamping device clamps, it presses on the upper module and the lower module, reducing the influence of the clamping device on the sample, and by removing the separation block, the support for the part estimated to be damaged on the sample is reduced, so as to improve the accuracy of the data measured in the tensile test.

[0009] Preferably, the upper module and the lower module are provided with insertion slots, the separation block is fixedly provided with insertion blocks, and the insertion blocks are inserted into the insertion slots; the separation block is provided with a relief hole and a connection hole, and a fixing bolt is threadedly connected to the connection hole; when the two separation blocks are pressed against each other, the two fixing bolts respectively pass through the relief holes and then press against the other separation block.

[0010] By adopting the above technical solution, when preparing the sample of the photovoltaic edge sealant, the state of the inner cavity is stable, so that the production effect of the sample is improved, which is beneficial to improving the accuracy of the tensile test.

[0011] Preferably, a handle is fixedly provided on the separation block.

[0012] By adopting the above technical solution, when removing the separation block from the upper module and the lower module, it is easier to operate by holding the handle.

[0013] Preferably, a demoulding aid is placed on the surface of the separation block close to the inner cavity.

[0014] By adopting the above technical solution, when removing the two separation blocks from the upper module and the lower module before testing, it is avoided that the separation block damages the solidified photovoltaic edge sealant sample, destroys the surface of the sample and interferes with the test result, affecting the accuracy of the test.

[0015] Preferably, a convex block is fixedly provided in the inner cavity, there are a plurality of convex blocks, and the plurality of convex blocks are evenly distributed on the upper module and the lower module respectively.

[0016] By adopting the above technical solution, when performing a tensile test after the photovoltaic edge sealant solidifies in the inner cavity, the convex blocks play a limiting role on the photovoltaic edge sealant located between the upper module and the lower module, preventing the test sample from falling off between the upper module and the lower module during the tensile test.

[0017] In summary, the present application has the following beneficial technical effects: By manufacturing a tensile specimen in a specimen preparation device and fixing the specimen preparation device on a clamping device, and then removing two separation blocks from the upper module and the lower module respectively, the initial tension applied to the tensile specimen during installation is reduced; at the same time, by clamping the upper module and the lower module for tensile testing, the influence of the clamping device on the tensile specimen when directly clamping the tensile specimen is eliminated, which has the advantage of improving the test accuracy.

[0026] The following further elaborates on the present application Figures 1-4 for further detailed description.

[0027] A tensile testing machine for detecting the tensile strength of an adhesive includes a mounting table 1, a clamping device 2, and a sample preparation device 3.

[0028] A fixing frame 4 is fixedly arranged on the mounting table 1, and a mounting frame 5 is slidably arranged on the fixing frame 4; there are two clamping devices 2, and the two clamping devices 2 are respectively fixedly arranged on the mounting table 1 and the mounting frame 5; the sample preparation device 3 is fixedly arranged on the two clamping devices 2.

[0030] There are two separating blocks 7, and the two separating blocks 7 are respectively inserted into the upper module 6 and the lower module 8: insertion slots 11 are formed in the upper module 6 and the lower module 8, and an insertion block 12 is fixedly arranged on the separating block 7, and the insertion block 12 is inserted into the insertion slot 11.

[0031] A relief hole 13 and a connection hole 14 are formed in the separating block 7, and a fixing bolt 15 is threadedly connected to the connection hole 14; when the two separating blocks 7 are pressed against each other, the two fixing bolts 15 respectively pass through the relief hole 13 and then press against the other separating block 7. A handle 16 is fixedly arranged on the separating block 7.

[0032] When the two separating blocks 7 are in contact with each other, an inner cavity 17 is formed by the upper module 6, the two separating blocks 7, and the lower module 8; the injection hole 9 communicates with the inner cavity 17; a convex block 18 is fixedly arranged in the inner cavity 17, and there are four convex blocks 18, and the four convex blocks 18 are evenly distributed on the upper module 6 and the lower module 8 respectively; a demolding aid 19 is placed on the surface of the separating block 7 close to the inner cavity 17.

[0033] The implementation principle of this embodiment is as follows: before the tensile test, a demolding aid 19 is placed on the side of the two separation blocks 7 close to the inner cavity 17, and then the two separation blocks 7 are respectively plugged and set on the upper module 6 and the lower module 8, and the two separation blocks 7 are fixed together after passing through the clearance holes 13 by fixing bolts 15; then the liquid photovoltaic edge sealing glue is filled into the space of the inner cavity 17 through the injection hole 9, and the sealing block 10 is set on the injection hole 9 to close the inner cavity 17; after waiting for the photovoltaic edge sealing glue to solidify to form a tensile specimen 20, it is installed on the mounting table 1 The clamping device 2 is used to first fix the lower module 8, and then the position of the mounting frame 5 is adjusted so that the clamping device 2 installed on the mounting frame 5 clamps the upper module 6, so that the sample preparation device 3 is fixed on the tensile testing machine; then the fixing bolt 15 is unscrewed from the connecting hole 14 to disconnect the two separation blocks 7 from each other, and the two separation blocks 7 are disconnected away from each other by pulling the handle 16 by hand, so that the solidified photovoltaic edge sealing adhesive tensile specimen 20 is separated from the contact with the fixed component, and then the demolding aid 19 is removed from the exposed photovoltaic edge sealing adhesive tensile specimen 20, and the tensile test can be carried out.
