Description

Technical Field

[0001] This utility model belongs to the technical field of release force testing machine, specifically relating to a high-precision release force testing machine for release films. Background Technology

[0002] A release force tester is a specialized device used to measure the peel strength between materials, primarily for evaluating the release force performance of products such as tapes, labels, and films. Its working principle involves simulating the actual peeling process, separating the test material at a constant speed, and accurately recording the force changes during the peeling process. This equipment is widely used in quality control and R&D in industries such as adhesive products, packaging, and electronic materials to ensure that products meet release force standards. The tester typically features high-precision sensors, an automated control system, and data acquisition capabilities, providing stable and reliable test results to help optimize production processes and product performance.

[0003] Traditional release force testing machines require manual removal of air bubbles and wrinkles from the surface of the release film before testing. However, manual operation is prone to omissions or incomplete removal, resulting in poor removal effect. These residual air bubbles and wrinkles will change the actual contact state of the release film, thus affecting the accuracy of the release force test results. Utility Model Content

However, the present invention may also be implemented in other ways different from those described herein. Those skilled in the art can make similar extensions without departing from the spirit of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed below.

[0025] Secondly, the term "an embodiment" or "embodiment" as used herein refers to a specific feature, structure, or characteristic that may be included in at least one implementation of the present invention. The phrase "in one embodiment" appearing in different places in this specification does not necessarily refer to the same embodiment, nor is it a single or selective embodiment that excludes other embodiments.

[0026] Example

[0027] Reference Figure 1-4 This embodiment of the present invention provides a high-precision release force testing machine for release films, comprising:

[0028] The testing apparatus 100 includes a testing machine body 110 for testing the release force of the release film, and a standard substrate 120 for bonding the release film.

[0029] The removal mechanism 200 includes a rolling member 210 for rolling a release film adhered to a standard substrate 120, and a movement limiting member 220 for limiting the movement of the rolling member 210.

[0030] In this process, the release film pasted on the surface of the standard substrate 120 is rolled by the cooperation between the rolling component 210 and the moving limiting component 220 to eliminate bubbles and wrinkles on its surface. This solves the problem that the traditional release force testing machine does not achieve good results when relying on manual removal of bubbles and wrinkles, improves the flatness of the release film, and thus improves the accuracy of the release force test.

[0031] Specifically, the rolling component 210 includes a movable frame 211 slidably mounted on the movable limiting component 220, a rotating frame 212 rotatably mounted inside the movable frame 211, a pressure roller 213 rotatably mounted inside the rotating frame 212 for rolling the release film pasted on the surface of the standard substrate 120, and two spring-loaded hinges 214 fixedly mounted inside the movable frame 211 for maintaining the elasticity of the rotating frame 212;

[0032] The rotating frame 212 is rotatably connected to the spring-loaded hinge 214, and the surface of the standard base plate 120 is provided with a reserved groove for the movement of the movable frame 211.

[0033] Furthermore, a connecting plate 215 is fixedly installed on the surface of the movable frame 211, and a push-pull rod 216 for pushing the pressure roller 213 to move is fixedly installed on the surface of the connecting plate 215.

[0034] The connection between the connecting plate 215 and the push-pull rod 216 facilitates the movement of the movable frame 211, allowing the operator to move the pressure roller 213 to perform a rolling operation on the release film pasted on the surface of the standard substrate 120.

[0035] Preferably, a stop bar 217 for limiting the rotation frame 212 is fixedly installed on the inner side of the movable frame 211, and the stop bar 217 is engaged with one side of the rotation frame 212.

[0036] The stop bar 217 is used to limit the rotation frame 212 to prevent the rotation frame 212 from tilting the pressure roller 213 excessively under the elastic force of the spring hinge 214, which would cause the pressure roller 213 to be blocked by the standard base plate 120 when moving.

[0037] Furthermore, the width of the pressure roller 213 is the same as the width of the standard substrate 120, and the width of the inner side of the rotating frame 212 is greater than the width of the standard substrate 120.

[0038] Specifically, by setting the width of the pressure roller 213 to be the same as the width of the standard substrate 120, the pressure roller 213 can fully cover the release film, thereby improving the rolling effect on the release film. By setting the width of the inner side of the rotating frame 212 to be greater than the width of the standard substrate 120, the rotating frame 212 can move to the outside of the standard substrate 120.

[0039] Specifically, the top of the main body 110 of the testing machine is fixedly installed with a strip plate 221, a limiting groove 222 opened on the surface of the strip plate 221, and a limiting slider 223 fixedly installed on the surface of the movable frame 211 and located inside the limiting groove 222.

[0040] The limiting groove 222 and the limiting slider 223 are used to limit the movement of the movable frame 211, ensuring the movement stability of the pressure roller 213, thereby improving the rolling effect of the pressure roller 213 on the release film pasted on the surface of the standard substrate 120, and avoiding bubbles and wrinkles in the release film.

[0041] Furthermore, the dimensions of the limiting groove 222 and the limiting slider 223 are matched.

[0042] When using it, first stick one end of the release film to the top of the standard substrate 120, and then fix the other end of the release film in the fixture on the main body 110 of the testing machine;

[0043] The operator pushes the movable frame 211 with the push-pull rod 216, causing the movable frame 211 to move the pressure roller 213 closer to the standard substrate 120. The movable frame 211 slides between the two strip plates 221. The top of the standard substrate 120 is slightly higher than the bottom of the pressure roller 213. When the pressure roller 213 moves to one end of the standard substrate 120, the standard substrate 120 slightly lifts the pressure roller 213. Under the elastic force of the spring-loaded hinge 214, the pressure roller 213 is kept in contact with the top of the standard substrate 120. When the pressure roller 213 passes the top of the standard substrate 120, it rolls the release film to remove air bubbles and wrinkles, so as to avoid affecting the release force test data of the release film. After rolling the release film, the operator pulls the push-pull rod 216 to make the pressure roller 213 detach from the release film and return to its original position.

[0044] The release force of the release film is tested under the action of the main body 110 of the testing machine.

[0045] In summary, by cooperating with the rolling component 210 and the moving limiting component 220, the release film pasted on the surface of the standard substrate 120 is rolled to eliminate bubbles and wrinkles on its surface. This solves the problem that traditional release force testing machines rely on manual removal of bubbles and wrinkles and achieve poor results, improves the flatness of the release film, and thus improves the accuracy of the release force test.
