Abstract

This invention relates to a membrane toughness testing device and method with tension adjustment function, belonging to the technical field of membrane testing equipment. To address the problem of membrane slack during testing and poor fixation due to the thinness of the membrane, this invention utilizes an adjustment mechanism and a positioning mechanism. The upper end of the main frame is connected to the adjustment mechanism, and the inner wall of the main frame is connected to the positioning mechanism. The invention involves winding one end of the membrane onto a take-up tube, inserting a rotating rod into the tube, and then, when the membrane becomes slack, using a traction belt to slowly tighten the membrane, preventing excessively loose membrane from affecting testing quality. Simultaneously, when the membrane passes through the through-groove, it preferentially passes the extension rod, and as the membrane rotates, the extension rod also rotates, reducing the resistance experienced by the membrane and protecting it from tearing.

[0002] A thin film is a thin, flexible, transparent sheet made of plastics, adhesives, rubber, or other materials. Scientifically, a thin film is defined as a two-dimensional material formed by the deposition of atoms, molecules, or ions onto the surface of a substrate. Examples include optical thin films, composite thin films, superconducting thin films, polyester films, nylon films, and plastic films. Thin films are widely used in industries such as electronics, machinery, and printing. During the thin film production process, toughness testing is necessary, making thin film toughness testing equipment indispensable.

[0003] Currently, during the testing process of thin film toughness testing devices, the film may loosen, which indirectly affects the testing quality. Furthermore, adjusting the tightness of the film is quite troublesome. Secondly, when fixing the film, the thinness of the film leads to poor fixing effect, resulting in the film falling off, which affects the testing quality and work efficiency.

[0020] Compared with the prior art, the beneficial effects of the present invention are:

[0021] 1.

[0039] Specifically, one end of the film is wound onto the take-up tube 53, and then the rotating rod 55 is inserted into the take-up tube 53. When the film becomes slack, the traction belt 553 is pulled to slowly tighten the film, preventing the loose film from affecting the detection quality. At the same time, when the film passes through the through groove 13, it will preferentially pass through the extension rod 71. As the film rotates continuously, the extension rod 71 will also rotate, reducing the resistance on the film and protecting it from tearing.

[0040] To address the technical challenge of fixing the film with minimal damage, such as... Figure 4 , Figure 7 and Figure 8 As shown, the following preferred technical solutions are provided:

One end of the extraction cylinder 671 is connected to the main connecting ring 664. The magnetic suction plate 675 is magnetically connected to the clamping block 63.

[0044] Specifically, the film to be tested is placed in the clamping groove 64, and then the piston rod 672 is pulled to extract the air around the adsorption plug 663. The adsorption plug 663 is used to adsorb and fix the film. At the same time, the tension rod 674 is pulled to connect the magnetic suction plate 675 with the clamping block 63. On the one hand, the adsorption and fixation effect is good, and the film is not easy to fall off or loosen. On the other hand, the adsorption and fixation causes less damage to the film, provides better protection for the film, and saves costs.

[0045] To address the technical problem of how to reduce measurement errors, such as Figure 2 , Figure 5 and Figure 9 As shown, the following preferred technical solutions are provided:

[0046] The main frame 1 includes side grooves 11 on both sides of the main frame 1, recessed grooves 12 on both sides of the side grooves 11, through grooves 13 on the upper surface of the main frame 1, and side plates 14 inside the side grooves 11. T-shaped grooves 15 are provided on the outer surface of the side plates 14. Bottom grooves 21 are provided on both sides of the base 2.

The tension increasing module 81 automatically increases the tension of the main telescopic rods A41 and B61 step by step. Then, the tension reciprocating module 82 makes the main telescopic rods A41 and B61 automatically reciprocate. Finally, the tension detection module 83 is used to detect the tension. The tension detection module 83 is connected to the control panel 3.

[0049] Specifically, the transverse toughness and longitudinal toughness of the film are tested using the main telescopic rods A41 and B61, respectively. The tension of the main telescopic rods A41 and B61 is automatically increased step by step using the tension increment module 81. Then, the main telescopic rods A41 and B61 are automatically stretched back and forth using the tension reciprocating module 82, which makes the measured results more accurate and the error range smaller.

[0050] To further illustrate the above embodiments, the present invention also provides an implementation method for a thin film toughness testing device with tension adjustment function, comprising the following steps:

[0051] S1: Place the film to be tested into the clamping groove 64, then pull the piston rod 672 to extract the air around the adsorption plug 663 and use the adsorption plug 663 to fix the film.

[0052] S2: Wrap one end of the film around the take-up tube 53, then insert the rotating rod 55 into the take-up tube 53. When the film becomes slack, pull the traction belt 553 to slowly tighten the film.

[0053] S3: The transverse toughness and longitudinal toughness of the film are tested using the main telescopic rods A41 and B61 respectively. The tension of the main telescopic rods A41 and B61 is automatically increased step by step using the tension increment module 81. Then, the main telescopic rods A41 and B61 are automatically stretched back and forth using the tension reciprocating module 82. Thus, all implementation steps are completed.
