Description

Technical Field

[0001] The utility model relates to the technical field of viscosity testing devices, and particularly relates to a tape continuous viscosity testing device. Background Technique

[0002] As a widely used adhesive material, tapes are widely used in various industries such as packaging, electronics, construction, and automobiles. The viscosity of tapes is a key indicator for evaluating their quality and applicability. Therefore, the testing of tape viscosity is particularly important. Traditional tape viscosity testing methods mainly include tests such as initial adhesion, holding adhesion, and shear force. These testing methods help to understand the performance of tapes under different conditions.

[0003] Currently, there are a variety of tape viscosity testing devices on the market, but they generally have problems such as inconvenient use, large structural volume, and unsuitability for tape viscosity testing on different interface surfaces. Traditional testing devices usually adopt fixed brackets and standardized test plates. Although they can provide a certain degree of testing accuracy, their bulky structure and single testing environment limit their application scope.

[0004] Test personnel need to spend a lot of time and energy to operate. This complexity not only increases the testing cost but also easily leads to operation errors and affects the accuracy of test results. The viscosity performance of tapes may vary significantly on interfaces with different materials and surface roughnesses. However, existing testing devices usually can only be tested on standardized test interfaces and cannot truly reflect the viscosity performance of tapes in actual use environments. Therefore, the reference value of test results is limited and it is difficult to meet diverse testing requirements.

[0005] In view of this, in response to the existing problems, research and improvement are carried out to provide a tape continuous viscosity testing device to solve the current problems, aiming to achieve the purpose of solving problems and improving practical value through this technology.

[0025] To make the objectives, technical solutions and advantages of the present utility model clearer and more understandable, the present utility model will be further described in detail below in conjunction with the specific embodiments and with reference to the accompanying drawings. It should be noted that, without conflict, the embodiments of the present utility model and the features in the embodiments may be combined with each other.

[0026] It should be understood that these descriptions are only exemplary and are not intended to limit the scope of the present utility model.

[0027] Some embodiments of the present utility model will be described below with reference to the accompanying drawings to provide a tape continuous adhesion test device.

[0028] Combined with Figures 1 - 5As shown in the figure, a tape continuous adhesion testing device provided by the utility model includes a guide sleeve seat 100, a driving box 200, a lifting and testing assembly 300, and a clamping assembly 400 for positioning and clamping the tape. The driving box 200 is fixedly installed on the surface of the guide sleeve seat 100, and a motor 210 is fixedly installed on one side of the driving box 200. A transmission chain 220 fixedly connected to the surface of the lifting and testing assembly 300 is rotatably installed inside the driving box 200. The motor 210 is used to drive the transmission chain 220 to move. The lifting and testing assembly 300 includes a lifting slide base 310, a connecting strip 320, and a deformation tensiometer 330. The upper and lower ends of the connecting strip 320 and the deformation tensiometer 330 are connected to the top surface of the clamping assembly 400 and the bottom surface of the lifting slide base 310. The clamping assembly 400 is used to clamp the tape to be tested, and an electric heating patch 411 is embedded in the bottom surface of the clamping assembly 400.

[0029] In this embodiment, the lifting slide base 310 and the clamping assembly 400 are slidably installed inside the guide sleeve seat 100. A slide bar adapted to the inside of the guide sleeve seat 100 is provided on the surface of the lifting slide base 310.

[0030] Specifically, the motor 210 drives the lifting slide base 310 to lift and slide inside the guide sleeve seat 100, and is guided by the slide bar to improve the movement stability of the lifting slide base 310 and the clamping assembly 400.

[0031] In this embodiment, the connecting strip 320 is of a flexible connecting strip structure. The number of connecting strips 320 is several and they are evenly distributed in the circumferential direction on the outer periphery of the deformation tensiometer 330. The connecting strip 320 is in a curved arc shape in the initial state.

[0032] Specifically, the connecting strip 320 is used to connect the lifting slide base 310 and the clamping assembly 400. The length of the connecting strip 320 is equal to the maximum deformation length of the deformation tensiometer 330 to avoid damage to the deformation tensiometer 330 due to excessive stretching.

[0033] In this embodiment, the deformation tensiometer 330 is of a deformation tensiometer structure. The output end of the deformation tensiometer 330 is electrically connected to a digital display meter located on the surface of the guide sleeve seat 100.

[0034] Specifically, the adhesive strength is measured by this tensiometer.

[0035] In this embodiment, the clamping assembly 400 includes a clamp seat 410 and clamp ears 420 rotatably installed on both sides of the clamp seat 410. An elastic member 430 for elastic deflection of the clamp ears 420 is provided on the surface of the clamp seat 410.

[0036] Specifically, the tape is clamped and positioned on the surface of the clamp seat 410 by the elastic deflection of the clamp ears 420.

[0037] In this embodiment, the electric heating patch 411 is located on the bottom surface of the clamping seat 410, and the input end of the electric heating patch 411 is electrically connected to a constant temperature controller.

[0038] Specifically, the constant temperature controller is used to control the electric heating patch 411 to heat the tape at a constant temperature, so as to realize the high-temperature test of the tape.

[0039] The working principle and usage process of the present utility model are as follows:

[0040] During the continuous adhesion test of the tape, a certain length of the tape to be tested is cut and attached to the bottom surface of the electric heating patch 411, and is clamped and fixed by the elastic member 430 and the clamping ear 420. The device is placed in contact with different adhesive test interface surfaces for testing. Due to the gravity of the clamping seat 410, the tape is attached to the test interface surface. Under the lifting action of the internal structure of the driving box 200, the lifting slide seat 310 is lifted, which drives the connecting bar 320 and the deformation tension gauge 330 and drives the clamping assembly 400 to lift. The clamping assembly 400 drives the tape to lift. During the lifting process, the maximum tension between the lifting slide seat 310 and the clamping assembly 400 is measured by the deformation tension gauge 330. Or when the deformation tension gauge 330 maintains a certain tension value, the tape on the surface of the clamping assembly 400 is separated from the test interface, and the duration is detected, so as to realize the adhesion strength test and continuous adhesion test of the tape; at the same time, the tape can be heated by the electric heating patch 411 as needed to realize the adhesion strength test under a high-temperature environment.
