Abstract
Description
Technical Field
[0001] The present application relates to the technical field of adhesive testing, and in particular to a preparation tool for an adhesion test sample. Background Art
[0002] The main function of adhesives is to firmly bond two interfaces together. They are widely used in industries such as electronic packaging, building materials, aerospace, automobile manufacturing, and medical and health care. Adhesives are generally composed of resins, curing agents, coupling agents, toughening agents, diluents, and other small amounts of additives. The most important indicator parameter of adhesives is bonding performance, that is, the bonding strength of the adhesive at the bonding interface, or the degree of firmness. At present, the method for measuring the bonding strength of adhesives mainly uses the thrust shear test method to measure the bonding strength of adhesives on a certain substrate interface.
[0003] According to the national standard GB / T7124-2008 "Determination of tensile shear strength of adhesives", in general, the substrate 1 and substrate 2 are closely contacted with the adhesive at the adhesive position through an A-shaped clamp, but this process cannot determine the thickness of the adhesive layer. In addition, in the national standard GB / T7124-2008 "Determination of tensile shear strength of adhesives", specific requirements are made for the length and width of the adhesive. The width of the adhesive can be determined by controlling the width of the substrate, while the length of the adhesive is difficult to control, which inevitably reduces the measurement accuracy of the adhesive.

A second slide groove 211 is arranged on the bottom surface of the limit block 21. The second slide groove 211 extends along the first direction. Optionally, the second slide groove 211 passes through the limit block 21 along the first direction. The support plate 22 is located in the second slide groove 211. The support plate 22 is connected to the groove wall of the second slide groove 211 to maintain the position between the support plate 22 and the limit block 21 stable. The second substrate 200 is installed in the second slide groove 211 and is located between the support plate 22 and the bottom of the second slide groove 211; the support plate 22 has a second extension portion 221 on one side along the first direction, and the second extension portion 221 is located outside the second slide groove 211.

[0047] In this embodiment, the first direction, the second direction and the third direction are perpendicular to each other, wherein the second direction is the thickness direction of the height limiting block 11 and / or the position limiting block 21. Figure 1For example, the x-axis direction can be used as the first direction, the y-axis direction can be used as the second direction, and the z-axis direction can be used as the third direction. The side where the first extension portion 120 of the first tooling 10 is located faces the side where the second extension portion 221 of the second tooling 20 is located. After the first substrate 100 and the second substrate 200 are installed on the first tooling 10 and the second tooling 20 respectively, the first substrate 100 contacts the height limit block 11, and the second substrate 200 contacts the position limit block 21. It should be noted that the first substrate 100 can also be installed on the second tooling 20, and the second substrate 200 can be installed on the first tooling 10, and the present embodiment is not limited to this.
[0048] In this embodiment, the first tooling 10 is used in conjunction with the second tooling 20 to respectively install the first substrate 100 and the second substrate 200, and the first substrate 100 is pressed by the pressing plate 12, and the second substrate 200 is pressed by the supporting plate 22, which can effectively prevent the first substrate 100 and the second substrate 200 from warping or sinking, so that the first substrate 100 can fit tightly with the second substrate 200, thereby improving the bonding effect of the adhesive; the adhesive is filled between the first substrate 100 and the second substrate 200 to obtain an adhesion test sample to test the adhesion of the adhesive, wherein the width of the adhesive can be accurately defined by the width of the first substrate 100 and the second substrate 200, the length of the adhesive can be accurately defined by the distance between the height limit block 11 and the limit block 21, and the thickness of the adhesive can be accurately defined by the thickness of the height limit block 11 and the limit block 21, thereby achieving controllable adjustment of the length, width and thickness of the adhesive, reducing the influence of the structural defects of the adhesive filling layer on the test results, and improving the accuracy of the adhesive test results.
[0049] In one embodiment, referring to Figure 4 and Figure 8 , the length of the first extension portion 120 along the first direction is recorded as the first length, and the length of the second extension portion 221 along the second direction is recorded as the second length, the first length is equal to or substantially equal to the second length, when in use, the first extension portion 120 can be in contact with the limit block 21, and the second extension portion 221 can be in contact with the height limit block 11, so as to achieve precise alignment of the first tooling 10 and the second tooling 20, after the first substrate 100 and the second substrate 200 are installed, the first substrate 100 and the second substrate 200 are fully pressed together by the pressing plate 12 and the supporting plate 22 respectively to prevent warping or depression.
[0050] In one embodiment, the first length and the second length are both greater than 12.25 mm, and the widths of the first chute 111 and the second chute 211 are both greater than 24.75 mm, wherein the widths of the first chute 111 and the second chute 211 are the distances between the two groove walls on opposite sides thereof along the third direction. Further, the first length and the second length are both 12.25 mm to 12.75 mm, and the second length is 12.25 mm to 12.75 mm, for example, the first length and the second length can be set to 12.5 mm or other suitable values; the widths of the first chute 111 and the second chute 211 are greater than 25 mm, for example, the widths of the first chute 111 and the second chute 211 can be set to 27 mm or other suitable values.
[0051] In one embodiment, referring to Fig.10 , the distance between the bottom of the first chute 111 and the bottom surface of the height limiting block 11 is recorded as the bottom thickness of the chute, the overall height of the limit block 21 along the second direction is taken as the second thickness, and the bottom thickness of the chute is less than or equal to the second thickness, so that the first extension 120 can contact the limit block 21. When in use, the bottom surface of the limit block 21 is coplanar with the bottom surface of the height limiting block 11. When the second thickness of the limit block 21 is relatively small, the first extension 120 may be located above the limit block 21 along the second direction, so that the first extension 120 cannot contact the limit block 21, which will reduce the pressing effect on the first substrate 100. By controlling the bottom thickness of the chute and the second thickness, the alignment effect of the limit block 21 and the height limiting block 11 can be ensured, and the pressing effect of the first substrate 100 and the second substrate 200 can be ensured.
[0052] The thickness of the adhesive filled in the first substrate 100 and the second substrate 200 is the distance between the bottom of the first chute 111 and the bottom of the second chute 211 along the second direction. Optionally, the height of the height limit block 11 along the second direction is recorded as the first thickness, the depth of the first chute 111 is the same as the depth of the second chute 211, the first thickness is equal to the second thickness, the distance between the pressing plate 12 and the bottom of the first chute 111 is substantially equal to the thickness of the first substrate 100, and the distance between the supporting plate 22 and the bottom of the second chute 211 is substantially equal to the thickness of the second substrate 200, so that the top surface of the pressing plate 12 is substantially coplanar with the top surface of the limiting block 21, so that the preparation tooling of this embodiment is more compact. At this time, the thickness of the adhesive is the first thickness or the second thickness minus the thickness of the first substrate 100, the second substrate 200, the pressing plate 12 and the supporting plate 22.
[0053] In one embodiment, referring to Figure 3 and Figure 7, the distance between the pressing plate 12 and the bottom of the first chute 111 is greater than or equal to the thickness of the first substrate 100, and the distance between the two chute walls on the opposite sides of the first chute 111 is greater than or equal to the width of the first substrate 100, so as to provide sufficient installation space for the first substrate 100. The distance between the supporting plate 22 and the bottom of the second chute 211 is greater than or equal to the thickness of the second substrate 200, and the distance between the two chute walls on the opposite sides of the second chute 211 is greater than or equal to the width of the second substrate 200, so as to provide sufficient installation space for the second substrate 200. Among them, the two chute walls of the first chute 111 and the two chute walls of the second chute 211 are relatively distributed along the third direction, and the width of the first substrate 100 and the width of the second substrate 200 are both their widths along the third direction.
[0054] In one embodiment, the pressure plate 12 includes a first pressure plate 121 and a second pressure plate 122. The first slide groove 111 has a first groove wall and a second groove wall on two opposite sides along the third direction. The first pressure plate 121 is connected to the first groove wall, and the second pressure plate 122 is connected to the second groove wall. Optionally, the first pressure plate 121 can be detachably fixedly connected to the first groove wall, and the second pressure plate 122 can also be detachably fixedly connected to the second groove wall.
[0055] Further, refer to Figure 3 The first pressing plate 121 and the second pressing plate 122 are spaced apart along the third direction to facilitate installation of the first substrate 100 and observation of the installation of the first substrate 100. Optionally, the spacing distance between the first pressing plate 121 and the second pressing plate 122 along the third direction is recorded as a first distance, and the first distance is greater than 3 mm, for example, the first distance can be set to 3 mm, 5 mm or other suitable distances.
[0056] In one embodiment, referring to Figure 7 , a through slot 212 extending along the first direction is provided on the top surface of the limit block 21, and the through slot 212 and the second slide slot 211 are mutually connected. Optionally, the through slot 212 completely penetrates the limit block 21 along the first direction to divide the limit block 21 above the support plate 22 into two parts spaced apart from each other. By providing the through slot 212 on the limit block 21, it is possible to facilitate the installation of the second substrate 200 and observe the installation of the second substrate 200, and it is also helpful to fill the adhesive between the first substrate 100 and the second substrate 200. Further, the width of the through slot 212 along the third direction is recorded as the second distance, and the second distance is greater than 3 mm. For example, the second distance can be set to 3 mm, 5 mm or other suitable values.
[0057] To facilitate understanding of the preparation tooling of the adhesion test sample of this embodiment, it will be described below in conjunction with the specific implementation method. The first substrate 100 and the second substrate 200 are set as 100mm×25mm×2mm plain aluminum sheets; after completing the cleaning of the first substrate 100 and the second substrate 200, align the first tooling 10 with the second tooling 20, and make the pressing plate 12 abut against the limit block 21, and the support plate 22 abut against the height limit block 11; insert the first substrate 100 and the second substrate 200 into the first tooling 10 and the second tooling 20 through the first slide groove 111 and the second slide groove 211 respectively; fill the adhesive between the first substrate 100 and the second substrate 200, and scrape off the excess adhesive; after the adhesive surface is cured, pull out the first tooling 10 and the second tooling 20 to both sides respectively, and then obtain the adhesion test sample.
[0058] As described above, in this embodiment, the first tooling 10 is used in conjunction with the second tooling 20 to respectively install the first substrate 100 and the second substrate 200, and an adhesion test sample can be prepared after filling with adhesive; the first substrate 100 and the second substrate 200 are respectively pressed together by the pressing plate 12 and the supporting plate 22, which can effectively prevent the first substrate 100 and the second substrate 200 from warping or sinking, and enable the first substrate 100 to fit tightly with the second substrate 200, thereby reducing the influence of the structural defects of the adhesive filling layer on the test results and improving the accuracy of the adhesive test results; and in the adhesion test sample, the length of the adhesive can be determined by the distance between the limit block 21 and the height limit block 11, and the thickness of the adhesive can be determined by the thickness of the limit block 21 and the height limit block 11, so that the length and thickness of the adhesive are adjustable and can adapt to a variety of test scenarios. It can be seen that the preparation tooling of the adhesion test sample of this embodiment effectively reduces the risk of structural defects in the adhesive filling layer, improves the accuracy of the adhesive test results, and makes the length, width and thickness of the adhesive precisely adjustable, which can adapt to a variety of application scenarios and has extremely high market promotion value and industrial application value.
