[0002] Release film refers to a film whose surface can be distinguished. Release film does not have adhesiveness or only slight adhesiveness when in contact with specific materials under limited conditions. Peel strength refers to the maximum force required to peel materials that are bonded together from the contact surface per unit width. It reflects the bonding strength of the materials, such as safety film and glass, mobile phone screen protector, etc.

[0003] Existing release films are difficult to test accurately in terms of adhesion after production. Therefore, this application proposes an antistatic release film adhesion testing device. Utility Model Content

[0005] Therefore, the technical solution adopted by this utility model is as follows: an antistatic release film adhesion force testing device, comprising: a main body and a testing mechanism, wherein the main body includes a frame, a base installed at the bottom of the frame, clamps symmetrically arranged on the base, a driving component disposed in the inner cavity of the base and passing through the relative clamps, a film plate disposed between the relative clamps, and a release film body adhered to the film plate.

[0006] The detection mechanism includes a first electric telescopic rod symmetrically fixed to the top of the frame, a detection component fixed to the bottom of the first electric telescopic rod, a second U-shaped plate fixed to the bottom of the detection component, a fixing component installed on one side of the second U-shaped plate, a third electric telescopic rod symmetrically fixed to one side of the frame, a side plate fixed to the end of the third electric telescopic rod, and multiple semiconductor heating elements installed on the side plate.

[0007] The detection components include a base plate fixed to the bottom end of the first electric telescopic rod, pressure sensors symmetrically installed on the top of the base plate, and a first U-shaped plate passing through the base plate.

[0008] In a preferred embodiment, the present invention can be further configured such that: the top of the base has a groove, and the clamping plate includes a threaded sleeve that is movably fitted into the groove and a clamping seat fixed to the top of the threaded sleeve.

[0009] In a preferred embodiment, the present invention can be further configured such that the driving component includes a double-ended screw rotatably mounted on the inner wall of the groove and a knob disposed on one side of the base and whose end is fixedly connected to the end of the double-ended screw, wherein the double-ended screw passes through a threaded sleeve and the two mesh with each other.

[0023] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to specific embodiments and accompanying drawings. It should be noted that, unless otherwise specified, the embodiments and features of the present utility model can be combined with each other.

[0024] Some embodiments of this utility model are described below with reference to the accompanying drawings.

[0025] Example 1:

[0026] Combination Figure 1-5 As shown, this embodiment provides an antistatic release film adhesion force testing device, including: a main body 100 and a testing mechanism 200.

[0027] The main body 100 includes a frame 110, a base 120 installed at the bottom of the frame 110, clamping plates 130 symmetrically arranged on the base 120, a drive member 140 disposed in the inner cavity of the base 120 and passing through the clamping plates 130, a membrane plate 150 disposed between the clamping plates 130, and a release film body 160 adhered to the membrane plate 150.

[0028] The frame 110 is used to install other components. The top of the base 120 has a groove 121. The clamping plate 130 includes a threaded sleeve 132 that is movably fitted into the groove 121 and a clamping seat 131 fixed to the top of the threaded sleeve 132. Meanwhile, the driving component 140 includes a double-ended screw 141 that is rotatably installed on the inner wall of the groove 121 and a knob 142 that is located on one side of the base 120 and whose end is fixedly connected to the end of the double-ended screw 141. The double-ended screw 141 passes through the threaded sleeve 132 and the two are engaged with each other. When the user turns the knob 142, it drives the double-ended screw 141 to rotate. The rotation of the double-ended screw 141 drives the two threaded sleeves 132 to move towards each other, that is, it drives the clamping seat 131 to move towards each other, clamping and fixing the bottom end of the diaphragm plate 150 to ensure the stability of the diaphragm plate 150.

[0029] In addition, a rubber pad is provided on the outer side of the clamping seat 131, which can further increase the friction between the clamping seat 131 and the diaphragm plate 150 and improve the fixing effect.

[0030] The membrane plate 150 is used to adhere the release film body 160, which facilitates subsequent testing of the adhesion force of the release film body 160.

[0031] The testing mechanism 200 is used to test the adhesion force of the release film, including a first electric telescopic rod 210 symmetrically fixed to the top of the frame 110, a testing element 220 fixed to the bottom of the first electric telescopic rod 210, a second U-shaped plate 230 fixed to the bottom of the testing element 220, a fixing element 240 installed on one side of the second U-shaped plate 230, a third electric telescopic rod 250 symmetrically fixed to one side of the frame 110, a side plate 260 fixed to the end of the third electric telescopic rod 250, and a plurality of semiconductor heating elements 270 installed on the side plate 260.

[0032] The first electric telescopic rod 210 is used to install the detection component 220 and drive the detection component 220 to move. The detection component 220 includes a base plate 221 fixed at the bottom end of the first electric telescopic rod 210, pressure sensors 222 symmetrically installed at the top end of the base plate 221, and a first U-shaped plate 223 disposed through the base plate 221. The base plate 221 is used to fix the pressure sensor 222, the pressure sensor 222 is used to detect the downward pressure of the first U-shaped plate 223, and the first U-shaped plate 223 is used to fix the second U-shaped plate 230.

[0033] The fixing component 240 includes a second electric telescopic rod 241 symmetrically fixed to one side of the second U-shaped plate 230 and extending into the inner side of the second U-shaped plate 230, and a pressure plate 242 fixed to the end of the second electric telescopic rod 241. When the end of the release film body 160 is placed inside the second U-shaped plate 230, the second electric telescopic rod 241 drives the pressure plate 242 to press the end of the release film body 160 against the inner side of the second U-shaped plate 230, thus completing the fixing of the end of the release film body 160. At this time, the first electric telescopic rod... 210 drives the detection element 220 to move upward, and the upward movement of the detection element 220 drives the second U-shaped plate 230 to move upward, which in turn drives the end of the release film body 160 to move upward, peeling the release film body 160 off the film plate 150. During peeling, the greater the adhesion of the release film body 160, the greater the tension on the second U-shaped plate 230 and the first U-shaped plate 223. The pressure sensor 222 monitors the tension on the first U-shaped plate 223 in real time, so as to accurately test the adhesion of the release film body 160.

[0034] The third electric telescopic rod 250 is used to install the side plate 260 and drive the side plate 260 to move. The side plate 260 is used to install the semiconductor heating element 270. The semiconductor heating element 270 is used to heat the film plate 150, which facilitates the detection of the adhesion force of the release film body 160 at different temperatures.

[0035] The working principle and usage process of this utility model are as follows: In use, the film plate 150 with the release film body 160 bonded to it is placed between the opposing clamping seats 131. Rotating the knob 142 drives the double-ended screw 141 to rotate. The rotation of the double-ended screw 141 causes the threaded sleeves 132 on both sides to move towards each other, thus moving the clamping seats 131 towards each other to clamp and fix the bottom end of the film plate 150. The end of the release film body 160 is then placed inside the second U-shaped frame. The second electric telescopic rod 241 is activated, driving the pressure plate 242 to move and press the end of the release film body 160 against the inner surface of the second U-shaped frame. At this time, the first electric telescopic rod 210 is activated, driving the detection piece 220... The upward movement of the detection element 220 causes the end of the release film body 160 fixed on the second U-shaped frame to move upward, peeling the release film body 160 off the film plate 150. During this process, the greater the adhesion between the release film and the film plate 150, the greater the pressure detected by the pressure sensor 222, and vice versa. This enables the detection of the adhesion of the release film body 160. In addition, when it is necessary to test the adhesion of the release film body 160 at different temperatures, the third electric telescopic rod 250 is activated, causing the semiconductor heating plate 270 on the side plate 260 to adhere to the film plate 150 and heat the film plate 150, thereby testing the adhesion of the release film body 160 at different temperatures.

[0036] Although embodiments of the present invention have been shown and described, those skilled in the art will understand that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the claims and their equivalents.
