Technical Field

[0001] This utility model relates to the field of testing, and in particular to a device for testing the sag of adhesive. Background Technology

[0002] Adhesives, also known as adhesives, are substances with a sticky texture. In practical applications of adhesives (such as building bonding and electronic component packaging), if the adhesive sags excessively after being applied to a vertical surface, it may lead to uneven coating, insufficient bonding strength, or even product failure.

[0003] To this end, this application proposes an adhesive sag testing device to quantify the degree of sag of adhesives, help screen adhesive products that meet specific vertical construction requirements, and ensure their reliability in vertical operation scenarios. Utility Model Content

[0021] In the description of this utility model, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "joining" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model according to the specific circumstances. Example

[0022] Reference Figure 1 The present invention discloses a glue sag test device, which includes a base plate 1 and a vertical insert plate 2. Uprights 3 are provided on both sides of the upper surface of the base plate 1, and vertical slots 4 are provided on the upper surface of the two uprights 3. The opposite end faces of the two slots 4 are open, and the vertical insert plate 2 is vertically inserted into the two slots 4.

[0023] This utility model, by setting up a base plate 1, a vertical pole 3 and a vertical insertion plate 2, constitutes a verticality testing device with a simple structure and easy operation, providing a basic structural guarantee for the evaluation of the sag performance of adhesives. Specifically, the base plate 1 provides stable support for the device, and the vertical insert plate 2 can be vertically inserted into the slot 4 opened on the upright 3, providing a standardized vertical reference surface for subsequent testing.

[0024] A level bubble 5 is provided on the base plate 1, and four level adjustment components 6 are provided on the base plate 1. The four level adjustment components 6 are located at the four corners of the base plate 1 and arranged in a matrix array. Specifically, the leveling adjustment component 6 includes a screw 7 that is vertically set and threadedly connected to the base plate 1. The top end of the screw 7 is located above the base plate 1 and is provided with a knob 8. The bottom end of the screw 7 is located below the base plate 1 and is fixedly connected with a support foot 9.

[0025] Among them, the level bubble 5 is used to visually determine whether the base plate 1 is level. Before each test, observe the position of the level bubble 5 to quickly determine whether the base plate 1 needs to be adjusted. Adjust the height of the screw 7 by rotating the knob 8 to change the support height of the four corners of the base plate 1. With the observation of the level bubble 5, the base plate 1 is made to reach a level state, thereby ensuring that the vertical insert plate 2 inserted into the slot 4 of the upright 3 is strictly perpendicular to the horizontal plane, thus eliminating test errors from the basic level.

[0026] The front of the vertical insert plate 2 is provided with multiple test areas 10, and the multiple test areas 10 are set on the same horizontal line. This ensures that the initial height of each test area 10 is consistent, and the verticality measurement of multiple points can be carried out simultaneously on the same insert plate. Multiple samples (such as adhesives with different formulas and different batches) can be tested at the same time, and the test conditions are completely consistent, which improves the comparison efficiency and data reliability. Furthermore, the distance between the test area 10 and the top of the base plate 1 is greater than 40mm. This setting provides sufficient space for drooping and prevents the adhesive from drooping and contacting the base plate 1. In this embodiment, in order to correct the slight tilt after the vertical insert plate 2 is inserted (such as the slight tilt caused by the processing error of the slot 4 or the deformation of the insert plate itself), a sag compensation component 11 is added to both uprights 3 of the device, and the two sag compensation components 11 are located on one side of the vertical insert plate 2.

[0027] Specifically, the sag compensation component 11 includes a top block 12, two connecting rods 13, and two tension springs 14. A storage groove 15 adapted to the top block 12 is opened on one side inner wall of the slot 4. The top block 12 is arranged parallel to the vertical insert plate 2, and the top block 12 slides with the storage groove 15 and can be hidden inside the storage groove 15. A connecting groove 16 communicating with the outside is opened at the bottom of the storage groove 15. The connecting rod 13 is slidably arranged in the connecting groove 16, one end of which extends into the storage groove 15 and is connected to the top block 12. One end of the connecting rod 13 extends to the outside and is connected to a long rod 17. The tension springs 14 are arranged between the inner wall of the long rod 17 and the outer wall of the upright rod 3 and are wrapped around the circumferential surface of the connecting rod 13.

[0028] Furthermore, each pole 3 has two sag compensation components 11, with the two sag compensation components 11 located at the top and bottom of the pole 3 respectively, and the long pole 17 of the two sag compensation components 11 sharing the same one.

[0029] Furthermore, the top block 12 has a chamfer on the side away from the connecting rod 13.

[0030] When the vertical insert plate 2 is inserted into the slot 4 of the upright 3, the top block 12 will be squeezed by the vertical insert plate 2 and slide into the slot 15 because the inner wall of the slot 4 is provided with a storage groove 15. At the same time, the connecting rod 13 will move in the connecting groove 16, and the tension spring 14 will be stretched.

[0031] After the vertical insert 2 is inserted, if it is slightly tilted, the return force of the tension spring 14 will apply a pressing force to the top block 12 through the long rod 17 and the connecting rod 13, so that the top block 12 presses tightly against the other side of the vertical insert 2 to fix it in the slot 4; forcing the vertical insert 2 to adjust to a vertical state, thereby compensating for its sag error.

[0032] At this point, adhesive can be applied to the test area 10 of the vertical insert 2 to perform a verticality test and ensure the accuracy of the test results.

[0033] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit it. Although this utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some or all of the technical features therein. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of this utility model.
