[0029] Based on the above technical scheme, the adhesion performance test tool of the present application is installed on the test equipment through the first connecting piece 1 and the second connecting piece 6, wherein the first connecting piece 1 is used to apply a load. Since the first connecting piece 1 is connected with the second test plate 4 and the first test plate 3 and the second test plate 4 are adhered, the connection position of the second test plate 4 and the first connecting piece 1 will start to tear under the driving of the first connecting piece 1, so as to form a gap between the first test plate 3 and the second test plate 4, simulate the actual use scenario, and the load applied by the first connecting piece 1 is fed back to the test equipment for simulation analysis, so as to realize the purpose of adhesion performance evaluation. At the same time, since the first mounting piece 2 and the second mounting piece 5 define the plug-in space 8 located on the side, the first test plate 3 and the second test plate 4 can be directly inserted into the mounting space 7 from the side, so as to facilitate the test.

[0030] In some embodiments of the present application, as shown in Figures 1-5 The first connecting piece 1 includes a plug-in block 11 and a pressing rod 12. The plug-in block 11 is used to connect the test equipment. One end of the pressing rod 12 is connected to the lower part of the plug-in block 11, and the other end of the pressing rod 12 extends into the mounting space 7. The plug-in block 11 is provided with a plug-in hole for connecting the test equipment. The test equipment applies a load to the plug-in block 11 and transmits the load to the second test plate 4 through the pressing rod 12, so that a gap is generated between the first test plate 3 and the second test plate 4. The use of this split structure can more simply and conveniently realize the replacement of the pressing rod 12, and the adhesion performance test of test plates of different sizes can be realized by changing the pressing rod 12 of different sizes.

[0031] Specifically, as shown in Figures 1-5 The first connecting piece 1 further includes a pressing block 13 connected to one end of the pressing rod 12 close to the second test plate 4, and the pressing block 13 is connected to the mounting space 7. The pressing block 13 and the pressing rod 12 can be used in pairs. By replacing the pressing block 13, the adhesion performance test of test plates of different sizes can be simulated.

[0032] In some embodiments of the present application, as shown in Figures 1-6As shown, the first mounting member 2 comprises a first base 21, a pressing block 22, a first fastener 23 and a second fastener 24, the first base 21 is mounted on the second mounting member 5 through the first fastener 23, the pressing block 22 is mounted on the first base 21 through the second fastener 24, the first base 21 and the second mounting member 5 define the mounting space 7 and the plug-in space 8, and the pressing block 22 is pressed above the mounting space 7. The first fastener 23 can simply and firmly mount the first base 21 and the second mounting member 5 together, the second fastener 24 can simply and firmly mount the first base 21 and the pressing block 22 together, the first base 21 is arranged above the second mounting member 5 to form a gap with the second mounting member 5 to realize the plug-in installation of the test board, and the pressing block 22 presses the test board to fix the test board in the mounting space 7, avoids the shaking of the test board caused by the loose installation, and makes the test data more accurate.

[0033] Specifically, as shown in Figure 4 , Figure 6 The first mounting member 2 further comprises an elastic member 25, the elastic member 25 is sleeved on the outside of the second fastener 24, and the elastic member 25 is in a compressed state when the second fastener 24 mounts the pressing block 22 on the first base 21. The pressing block 22 can press the test board in the mounting space 7, the second fastener 24 fixes the pressing block 22 on the first base 21, when it is needed to replace the test board, the second fastener 24 needs to be loosened, and the pressing block 22 needs to be removed before replacement, which is relatively troublesome, therefore, the replacement step can be simplified through the elastic member 25, because the elastic member 25 is in a compressed state after the installation of the second fastener 24, therefore, after the second fastener 24 is loosened, the elastic member 25 releases the elastic force to restore the natural state, thereby lifting the pressing block 22, and the replacement of the test board is more convenient.

[0034] Specifically, as shown in Figures 1-5 and Figure 7As shown, the second mounting member 5 includes a second base 51, a mounting seat 52, a third fastener 53 and a fourth fastener 54, the second base 51 is mounted to the second connecting member 6 by the third fastener 53, the mounting seat 52 is mounted to the second base 51 by the fourth fastener 54, the mounting space 7 is defined between the mounting seat 52 and the first base 21, and the first base 21, the mounting seat 52 and the second base 51 together define the plug-in space 8. The second mounting member 5 also adopts a split mounting manner, making it more convenient to replace each part structure, the third fastener 53 can conveniently and firmly mount the second base 51 and the second connecting member 6 together, the fourth fastener 54 can conveniently and firmly mount the mounting seat 52 and the second base 51 together, the second base 51 is the main structure connecting the first base 21 and the second connecting member 6, and the mounting seat 52 is the main structure accommodating the test plate, the test plate is inserted into the mounting seat 52 through the plug-in space 8, and the test plate is pressed by the pressing block 22, so that the test can be reliably performed.

[0035] More specifically, as shown in the figure, Figures 1-6 The pressing block 22 is arranged at the middle of the first base 21, the mounting seat 52 is correspondingly arranged below the pressing block 22, the pressing block 22 is provided with a first through hole 221 penetrating from top to bottom, the first base 21 is provided with a second through hole 211 penetrating from top to bottom at a corresponding position, the mounting seat 52 is provided with a fourth through hole 521 penetrating from top to bottom at a corresponding position, and the second base 51 is provided with a fifth through hole 511 penetrating from top to bottom at a corresponding position. The first connecting member 1 sequentially passes through the first through hole 221 and the second through hole 211 and extends into the mounting space 7. First of all, it needs to be pointed out that in order to ensure that the test tool can simply and effectively separate the first test plate 3 and the second test plate 4 to test the bonding performance of the two, the first test plate 3 located at the upper part of the second test plate 4 is provided with a third through hole 31 penetrating from top to bottom, so that the first connecting member 1 can be connected to the second test plate 4 below to generate a force to separate the first test plate 3 and the second test plate 4. In order to make the simulation scene closer to the real situation and make the simulation result more accurate, the first connecting member 1 is connected to the middle position of the second test plate 4 in the present application, and the first connecting member 1 can be directly connected above the second test plate 4 through the first through hole 221, the second through hole 211 and the third through hole 31. When the first connecting member 1 applies a load, the second test plate 4 will be torn down with the first test plate 3, so the fourth through hole 521 and the fifth through hole 511 need to be arranged on the mounting seat 52 and the second base 51 together, so that the second test plate 4 has a space to move downward, so that the test can be smoothly carried out.

[0036] More specifically, as shown in the figure, Figure 5 ,Figure 7 As shown in the figure, the mounting seat 52 is provided with a guide limiting block 522, the mounting seat 52 has a first side wall 523, a second side wall 524 and a third side wall 525 for forming the mounting space 7, the first side wall 523 and the third side wall 525 are oppositely arranged, the second side wall 524 is arranged opposite to the plug-in space 8, and the guide limiting block 522 is arranged on the first side wall 523 and / or the third side wall 525. The guide limiting block 522 has two main functions, one is to provide guidance for the insertion of the test board, and the other is to provide limiting for the test board after insertion. The guide limiting block 522 can gradually reduce the transverse dimension of the side of the mounting space 7 close to the plug-in space 8, thereby playing a guiding role in the process of inserting the test board, making it easier to enter the limiting part of the guide limiting block 522, and the limiting part can limit the fixed position of the test board to a smaller range, so that the connection position of the first connecting piece 1 and the second test board 4 is more accurate, preventing test problems caused by inaccurate connection position. Preferably, the gap between the limiting surface of the guide limiting block 522 and the test board is 0.1mm-0.5mm, which can well meet the purpose of accurate connection position.

[0037] In some embodiments of the present application, as shown in the figure, Figures 1-7 As shown in the figure, the first mounting piece 2 and the second mounting piece 5 have a cutout surface 9, and the distance between the cutout surface 9 and the center of the mounting space 7 is less than the distance between the other side walls of the first mounting piece 2 and the second mounting piece 5 and the center of the mounting space 7. The distance between the cutout surface 9 and the center of the mounting space 7 is closer, and when the size of the test board is small, the test board will only leave a small part outside after being inserted into place. If the length of the plug-in space 8 is not reduced by the cutout surface 9, it will be difficult to take out the test board, and more structures need to be disassembled to replace the test board, so the arrangement of the cutout surface 9 can effectively improve the test efficiency.

[0038] In some embodiments of the present application, as shown in the figure, Figure 1 、 Figure 3 、 Figure 5 、 Figure 6 As shown in the figure, the cutout surface 9 is provided with a grabbing space 10 extending towards the mounting space 7, and the grabbing space 10 communicates with the plug-in space 8. Since the size of the plug-in space 8 may be small, it is difficult for the experimenter to insert his fingers into the plug-in space 8 to take out the test board, so a grabbing space 10 can be opened inwardly in the cutout surface 9, which can facilitate the experimenter to operate and improve the test efficiency.

[0039] In summary, the bonding performance test tool of the present application is installed on a test device through the first connecting member 1 and the second connecting member 6, wherein the first connecting member 1 is used to apply a load, the installation space 7 can be used to place two test plates bonded together, the first connecting member 1 is connected with one of the test plates, under the driving of the first connecting member 1, the connection position of the two test plates will start to tear and form a gap, to simulate the actual use scenario, and the load applied by the first connecting member 1 is fed back to the test device for simulation analysis, to achieve the purpose of bonding performance evaluation, and at the same time, since the first mounting member 2 and the second mounting member 5 define the plug-in space 8 located on the side, the test plate can be directly inserted into the installation space 7 from the side, so that the test is facilitated.

[0040] The above is only the preferred embodiment of the present application, and it should be pointed out that those skilled in the art can make several improvements and substitutions without departing from the technical principles of the present application, and these improvements and substitutions should also be considered as the protection scope of the present application.
