Description

Technical Field

[0001] The utility model relates to the technical field of tape adhesion testing, in particular to a tape holding power tester. Background Art

[0002] A tape holding power tester is a professional instrument used to evaluate the holding power of a tape. Holding power refers to the ability of a tape to maintain an adhesive state under a certain load, which is usually determined by measuring the time it takes for the tape to peel off from the adhered surface under a constant load. The holding power test is an important part of the tape performance evaluation, especially in applications that require long-term adhesion. A tape holding power tester generally consists of a fixed fixture, a load system, and a timing device. Among them, the fixed fixture generally fixes multiple tape samples through a bracket and several test plates to ensure the stable position of the tape during the test. The load system generally includes weights, and standard weights are suspended at the free end of the tape to apply a constant pulling force. The weight of the weights is usually set according to relevant standards. The timing device generally measures the peeling time of the tape through an automatic timing system, which can automatically stop timing and record data when the tape peels off. In a specific tape holding power test, the tape is cut into tape samples of a certain size according to standard requirements, generally rectangular strips of a certain length and width, and one end of the sample is pasted on the test plate to ensure that there are no bubbles or wrinkles. A standard weight is suspended at the free end of the tape sample to apply a constant pulling force, and timing is started to record the time when the tape starts to bear the load. Continuously observe the state of the tape under the load until the tape completely peels off from the test plate. When the tape peels off, stop timing and record the time elapsed from the start of loading to complete peeling of the tape, and then obtain the holding power test result of the tape sample.

[0003] In the holding power test of the tape, it is usually necessary to conduct multiple parallel tests on the same product to reduce systematic errors and avoid the influence of random errors on the accuracy of the test results. Among them, the difference in the application pressure when the tape samples are pasted onto the test plate between different test groups is one of the sources of systematic errors. Therefore, ensuring the consistency of the application pressure when the tape samples are pasted onto the test plate between different test groups is an important measure to reduce test errors. However, the existing tape holding power testers lack a force application mechanism to ensure the consistency of the pasting pressure between different tape samples, resulting in insufficient accuracy of the tape holding power test results.

The bottom end of the bracket 200 is connected to the top of the main body 100, and a plurality of test plates 300 are correspondingly connected to the top end of the bracket 200. The rolling mechanism 400 is installed on the bracket 200 in cooperation with the plurality of test plates 300 to roll the surface of each test plate 300. Specifically, the rolling mechanism 400 includes a driving unit 410 and a rolling unit 420. The driving unit 410 and the rolling unit 420 are both installed on the bracket 200. Among them, the rolling unit 420 is disposed on one side of the plurality of test plates 300, and the output end of the driving unit 410 is drivingly connected to the rolling unit 420, so that the driving unit 410 can drive the rolling unit 420 to roll the surface of the plurality of test plates 300. In practical applications, one end of the tape to be tested is adhered to the surface of one side of the plurality of test plates 300 facing the rolling unit 420, and the driving unit 410 drives the rolling unit 420 to roll the tape adhered to the surface of each test plate 300, so that the tape can be pressed and adhered to the corresponding test plate 300 surface under the preset pressure condition, so as to ensure the consistency of the pressure received when the tape adheres to the test plates 300 among different test plates 300, thereby reducing the test error and improving the accuracy of the tape holding adhesiveness test result.

[0026] Furthermore, the rolling mechanism 400 further includes a limiting unit 430. The limiting unit 430 is correspondingly disposed on the other side of the plurality of test plates 300 with respect to the rolling unit 420. When the driving unit 410 drives the rolling unit 420 to roll the surface of one side of the plurality of test plates 300, the limiting unit 430 can abut against the surface of the other side of the plurality of test plates 300, thereby restricting the plurality of test plates 300 from swinging relative to the bracket 200, so as to ensure the effectiveness of the rolling action of the rolling unit 420 on the plurality of test plates 300.

[0027] Further, the bracket 200 is arranged as a frame structure having two support columns 210 and a mounting beam 220.

[0028] Further, the rolling mechanism 400 further includes two eccentric bearings 440. The two eccentric bearings 440 are respectively arranged at both ends of the rolling unit 420. Thus, both ends of the rolling unit 420 are connected to the two support columns 210 through the two eccentric bearings 440. Specifically, one end of each eccentric bearing 440 is correspondingly connected to the end of the rolling unit 420; the other end of each eccentric bearing 440 is cooperatively connected to the support column 210; the output end of the driving unit 410 penetrates through one of the support columns 210 and is drivingly connected to the corresponding eccentric bearing 440. Thus, the driving unit 410 can drive the rolling unit 420 to perform a reciprocating motion parallel to the limiting unit 430 to realize the rolling of the surfaces of the plurality of test plates 300. In this embodiment, both the rolling unit 420 and the limiting unit 430 are arranged as roller structures, and the side surfaces of the rolling unit 420 and the limiting unit 430 respectively cooperate with the two side surfaces of each test plate 300, so that the rolling unit 420 can fully contact and roll the surface of the test plate 300 to improve the effectiveness of the rolling action.

[0029] Further, the main machine 100 includes a chassis 110 and a plurality of weights 120. The chassis 110 is arranged at the bottom end of the bracket 200 to connect and support the bracket 200, and the plurality of weights 120 are received inside the chassis 110.

In practical applications, when one end of the tape to be tested is connected to the corresponding test plate and firmly bonded by rolling through the rolling mechanism 400, the other end of the tape is connected to a weight 120, and thus the holding adhesion of the tape is started to be tested.

[0030] Further, the tape holding adhesion tester 10 further includes a plurality of connectors 500, and the plurality of connectors 500 respectively correspond to the plurality of weights 120; one end of each connector 500 is connected to the weight 120, and the other end thereof is connected to the corresponding tape to be tested, so as to improve the connection convenience and stability between the weight 120 and the tape.

The bottom end of the bracket is connected to the top of the main body, the plurality of test plates are correspondingly connected to the top end of the bracket, and the rolling mechanism is installed on the bracket in cooperation with the plurality of test plates to roll the surface of each test plate.
