[0021] Embodiment 1

[0023] The film adhesion force testing device described in this embodiment performs adhesion force testing on two films 400 to be tested that are bonded to each other through at least one testing mechanism 200, thereby quantifying the adhesion strength of the film product. At the same time, the film-to-film testing method adopted in the present application maximizes the simulation of the real adhesion scene, thereby enabling the operator to accurately classify and test the product through specific numerical values. Compared with conventional judgment methods, the present application has significant advantages such as high detection accuracy, stable detection effect, simple structure, low preparation cost and easy operation, and is a new film adhesion force testing device with broad application prospects.

[0024] See also Figure 1 As shown, the test bench 100 in this embodiment is preferably a rectangular plate with a horizontal upper surface, and the test bench 100 also includes a plurality of legs 140, and the plurality of legs 140 are supported on the lower surface of the platform 110, and the legs 140 include a telescopic structure, and the legs 140 adjust their extension lengths through the telescopic structure. In this embodiment, four legs 140 are provided, and the four legs 140 are respectively supported on the four corners of the lower surface of the platform 110, and they are all set to a height-adjustable structure (not shown in the figure). Based on this, the test bench 100 in this embodiment can adjust the height and level of its processing surface, thereby ensuring the accuracy of the test results. Correspondingly, the test bench 100 also includes a level 120, and the level 120 is arranged on the upper surface of the platform 110 and is located in the test space. Specifically, when the level 120 detects that the test bench function is in a non-horizontal state, it can adjust the level of the test bench through the legs 140 at the corresponding position.

[0025] In the present embodiment, the test bench 100 further includes a heating panel 130, which is connected to the upper surface of the platform 110, and its coverage area is not less than the test space. The heating plate can adjust the actual detection temperature. Since the adhesion between the films is greatly affected by the temperature, when the temperature increases, the migration speed of the additives in the film increases. Therefore, the present application can also test the film adhesion force at different temperatures. Therefore, compared with conventional test methods, the present application has a larger test range and a more flexible simulation effect. Furthermore, the heating panel 130 in the present embodiment can be detachably connected to the upper surface of the platform 110, and the present utility model does not make specific restrictions on the connection method between the heating panel 130 and the platform 110.

Correspondingly, the clamping member 220 includes two second fixing plates, and the second film to be tested is connected between the two second fixing plates; the first film to be tested and the second film to be tested both extend toward the test space, and the two are located on the same straight line. Further, one end of the second film to be tested is clamped between the two second fixing plates, and the other end extends toward the first film to be tested, and there is an overlapping part between the first film to be tested and the first film to be tested. In this embodiment, the adhesion force between the films is detected by the overlapping part between the first film to be tested and the second film to be tested. Further, in this embodiment, the first film to be tested and the second film to be tested have the same size, both set to 160mm×20mm, and the length of the overlapping part between the two is about 100mm.

[0027] In the present embodiment, the movable arm 240 is used to carry the clamping member 220 to move on the test bench 100, and the movable arm 240 includes a sliding part and a connecting part. The lower surface of the table body 110 is provided with a slide rail, and the sliding part is slidably embedded in the slide rail. The connecting part is arranged on the upper surface of the table body 110 and moves through the sliding part. Among them, the sliding part is slidably connected to the bottom of the test bench 100, which is preferably an "L"-shaped element, and the two are connected by a slide rail structure. In other embodiments, the movable arm 240 can also be connected by other structures that can realize relative sliding movements, and the present invention does not have any specific restrictions on this. In the present embodiment, the connecting part is horizontally arranged and spaced apart from the upper surface of the table body 110, and it is used to realize the connection with the mechanical sensor 230. Similarly, the present invention does not make any specific restrictions on the specific connection method between the movable arm 240 and the mechanical sensor 230. In the present embodiment, the moving speed of the movable arm 240 is controlled between 100mm / min-250mm / min,

[0028] The present embodiment also includes a conveying mechanism, and the pressing module 250 is connected to the moving end of the conveying mechanism. The conveying mechanism is used to place the pressing module 250 at the overlap of the first film to be detected and the second film to be detected, thereby trying to simulate different pressing times. Further, under normal conditions, the pressing module 250 can be placed on the platform 110. The present embodiment does not limit the specific structure of the conveying mechanism, which can be set as a mechanical arm, a conveying robot or a conveying module, etc. The pressing module 250 in this embodiment has a size of 150mm×50mm and a weight of 5kg.

[0029] See also Figure 1As shown, the present embodiment also includes a control mechanism 300, and the clamping member 220 and the movable arm 240 are respectively connected to the control mechanism 300, thereby the automation degree and the test efficiency of the present testing device can be further improved through the control mechanism 300. Furthermore, the control mechanism 300 in the present embodiment can also be connected to the heating panel 130, the support leg 140 and the mechanical sensor 230.

[0030] The specific use process and principle of the film adhesion test device in this embodiment are described below:

[0031] First, the first film to be tested and the second film to be tested need to be connected to the fixing member 210 and the clamping member 220 respectively, and at the same time, it is necessary to ensure that the first test film and the second test film overlap with each other, and then adjust the heating panel 130. At the same time, the conveying mechanism places the pressing module 250 at the overlapping position of the first film to be tested and the second film to be tested, presses it and returns it to its original position, and then starts the moving arm 240 to generate relative tension between the first film to be tested and the second film to be tested. At this time, the mechanical sensor 230 can provide real-time feedback on the specific value of its tension. The value when the two films are separated is the adhesion force between the two films.

At the same time, the film-to-film testing method adopted in the present application maximizes the simulation of the real adhesion scene, thereby enabling operators to accurately classify and detect products through specific numerical values.
