The base mechanism 100, which is a detection platform of the present application, is detachably mounted between two groups of base mechanisms 100, and can clamp and fix the adhesive tape test piece 600 to be detected, thereby facilitating the bending and rigidity test.
The clamping mechanism 200, which specifically includes a clamp sleeve 210, is used to secure the base mechanism 100 and to connect the base mechanism 100 to the linkage mechanism 300, and is rotatable as the tape test piece 600 bends with the base mechanism 100.
The base mechanism 100 specifically includes a rubber member 110, an upper base 120, a lower base 130, and a symmetrical spacer 140.
The upper base 120, which is in particular a sector shape, is fixed to the upper surface of the clamp sleeve 210.
The lower base 130, which is embodied as a sector, is fastened to the lower surface of the clamp sleeve 210 by bolts, thus facilitating installation and adjustment of the interval between the upper base 120 and the lower base 130.
The rubber member 110, which is embodied in a U shape, is disposed between the upper and lower bases 120 and 130, and has a bottom surface connected to an end surface of the clamp sleeve 210, and both ends of the tape test piece 600 may be inserted into the rubber member 110 and clamped by the upper and lower bases 120 and 130.
The gasket 140, which is embodied in a hemispherical shape, is respectively provided on the upper and lower bases 120 and 130, and is respectively in contact with the upper and lower surfaces of the tape test piece 600, is for protecting the tape test piece 600, and prevents the upper and lower bases 120 and 130 from clamping the tape test piece 600.
The link mechanism 300 has both ends connected to the clamping mechanisms 200, respectively, and is used for linking the clamping mechanisms 200 on both sides.
The link mechanism 300 specifically comprises two symmetrical fan-shaped sheet metal parts 310 and a bolt and nut assembly 320, wherein the two fan-shaped sheet metal parts 310 are connected through the bolt and nut assembly 320 and can freely rotate around the bolt and nut assembly 320 respectively, so that the interval between the two clamping mechanisms 200 can be adjusted, and the test length of the adhesive tape test piece 600 can be adjusted.
One end of each sector sheet metal part 310 is connected with one clamp sleeve 210, and the sector sheet metal parts 310 can rotate in the clamp sleeve 210.
Angle sensor assembly 400 specifically includes an angle sensor 410 and a central axis 420, angle sensor 410 is coupled to clamp sleeve 210 via central axis 420, and one end of fan-shaped sheet metal part 310 is also coupled to central axis 420, such that fan-shaped sheet metal part 310, clamp sleeve 210, and angle sensor 410 can simultaneously rotate about central axis 420.
Through the connection of the structure, the clamp sleeve 210 can rotate along with the bending of the base mechanism 100, so that when the adhesive tape test piece 600 is bent, the clamp sleeve 210 can rotate along the center shaft 420, the angle sensor 410 positioned in the clamp sleeve 210 can also rotate along the center shaft 420, the bending angle of the adhesive tape test piece 600 can be directly obtained through the tested rotation angle of the angle sensor 410, and the detection efficiency and the detection precision are greatly improved.
The load cell assembly 500, which is disposed on the clamp sleeve 210, is used to test the bending moment of the tape test piece 600.

The bending moment testing method of the load cell assembly 500 is specifically as follows:
as shown in fig. 4, in the bending stiffness test, a bending moment M is applied to the adhesive tape by the clamp head a and the clamp head B (the clamp head a and the clamp head B correspond to the gaskets 140 at both ends), the adhesive tape is deformed into a 'and B' by the bending moment, and at this time, the deformation angles θ1 and θ2 (θ1=θ2=θ in this example) recorded by the angle sensor assembly 400 after both ends are bent are corresponding to the deformation angles θ1 and θ2 (m=fl), and the curvature ρ=e/M of the deformed adhesive tape (where E is bending stiffness) is e=mρ=fl=ρ=fl (L/(θ1+θ2))=fl 2/2θ.
As in the present example, with the design l=200mm, taking the above formula, e=0.02F/θ (N/m) can be obtained, and therefore, by reading the value θ sensed by the angle sensor assembly 400 and the value F sensed by the force sensor assembly 500, the bending stiffness value E of the sample to be measured can be directly displayed on the touch display screen by the operation of the background control system.
And the background control system is respectively connected with the force sensor connecting piece 520 and the angle sensor 410 and is used for receiving the moment value and the angle value sent by the force sensor connecting piece 520 and the angle sensor 410, and calculating and analyzing the moment value and the angle value.
The background control system may specifically include a control box and a touch display screen, where the control box is connected to the load cell connector 520 and the angle sensor 410 through wires, respectively, and the control box may calculate and analyze the received moment value and angle value, and then display the analyzed structure through the touch display screen.
The specific working process of the application is as follows:
firstly, assembling a base mechanism 100, two groups of symmetrical clamping mechanisms 200, a connecting rod mechanism 300, an angle sensor assembly 400 and a force measuring sensor assembly 500;
then the adhesive tape test piece 600 is installed between two groups of symmetrical clamping mechanisms 200 along the longitudinal direction, the two ends of the adhesive tape test piece are aligned with the rubber piece 110, and then the control box is respectively connected with the force sensor connecting piece 520 and the angle sensor 410 through leads, so that the operation can be realized;
when the device works, a detection button on the external touch display screen is pressed to enable the detector to be in a horizontal position, then the adhesive tape test piece 600 is bent by hand, and then the effective bending rigidity of the detected adhesive tape test piece 600 is displayed on the external touch display screen through calculation and analysis of the control box through the angle sensor 410 and the force sensor 510;
after the detection is completed, the tape test piece 600 is taken out in reverse order and the detection of the next tape test piece 600 can be performed.
