Abstract
Description
Technical Field
[0001] This utility model relates to the field of testing device technology, specifically a release film peel force testing device. Background Technology
[0002] Peel strength refers to the maximum force required to peel materials bonded together from the contact surface per unit width. It reflects the adhesive strength of the materials, such as safety film and glass, mobile phone screen protectors, etc. In the production process of release film, it is usually necessary to bond the release film to the film plate for peel strength testing to determine the adhesive strength of the release film.
[0003] Chinese patent provides a release film peel force testing device, publication number CN221260764U, which includes a base plate and a motor. A support block is fixedly connected to the top of the base plate, and a rotating disk is rotatably connected to the top of the support block. Multiple clamping components are provided on the top of the rotating disk.
[0004] The aforementioned device controls an electric push rod to move a sliding block away from the support block, and pulls the release film off through the upper and lower clamping plates. When the release film is completely peeled off from the film plate, the tensile force is monitored by a digital display force gauge. The tensile force value is used to test the peel strength of the release film, which is convenient for replacing it with a film plate for testing.
[0005] However, the release liner's peeling structure is relatively simple, only able to peel the release film horizontally. It is difficult to adjust the release liner peeling method as needed, resulting in low flexibility. Furthermore, the film is only held by a push plate, making the structure relatively simple. During release liner peeling, the template is easily moved, affecting the stability of the test. Utility Model Content

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0024] Example 1
[0025] Combination Figures 1-4 A release film peel force testing device includes a support platform 1, a support frame 2 fixedly installed at the front of the top of the support platform 1, a rotating plate 3 rotatably installed at the top of the support frame 2 via a rotating rod, a plurality of fixed frames on the rotating plate 3, and electric telescopic rods 4 installed on both sides of the fixed frames, and a peeling component 8 is provided at the rear of the top of the support platform 1.
[0026] See Figure 2 and Figure 3Furthermore, the stripping assembly 8 has a rotating frame 9 and a movable frame 10. The rotating frame 9 is rotatably mounted on the front end of the movable frame 10. An electric telescopic rod 11 is movably mounted on the top of the movable frame 10. The push rod end of the electric telescopic rod 11 is connected to the upper rear end of the rotating frame 9 via a connecting seat. A digital display force gauge 14 is provided at the rear end of the movable frame 10. A slider is installed at the bottom end of the digital display force gauge 14, and the slider is slidably connected to the support platform 1. An electric telescopic rod 12 is installed on the top of the rotating frame 9. The push plate end of the electric telescopic rod 12 penetrates the rotating frame 9. A movable clamping plate 13 is installed at the top of the rotating frame 9. Anti-slip pads are provided on the inner top surface of the rotating frame 9 and the bottom surface of the movable clamping plate 13. Anti-detachment push plates 5 are fixedly installed at the ends of the two electric telescopic rods 4. A diaphragm plate 6 is provided on the inner side of the two anti-detachment push plates 5. The top surface of the diaphragm plate 6 is lower than the top surface of the rotating frame 9. A slot is provided at the front end of the diaphragm plate 6. A plug block that is compatible with the slot is fixedly connected to the end of the fixed frame away from the center point of the support frame 2. An electric telescopic rod 15 is installed at the rear of the top of the support platform 1. The push rod end of the electric telescopic rod 15 is connected to the rear end of the slider.
[0027] Specifically, multiple membrane plates 6 are used to adhere the release film. The membrane plates 6 are secured to the fixing frame by inserts, and the sides of the membrane plates 6 are restricted by anti-detachment push plates 5 to improve the stability of the membrane plates 6 and reduce the probability of displacement during pulling. Multiple membrane plates 6 are mounted on a rotating plate 3, which is rotatably mounted on a support frame 2. A rotary motor 17 can be activated as needed to rotate the rotating plate 3, moving the membrane plates 6 to the position of the electric telescopic rod 11 and the rotating frame 9. Then, the electric telescopic rod 12 can be activated, causing the movable clamping plate 13 to descend, thus clamping the release film. After holding the release film, the push rod of the electric telescopic rod 15 can be retracted to drive the rotating frame 9 to move away from the membrane plate 6, thereby peeling off the release film pasted on the membrane plate 6. When the release film is completely peeled off from the membrane plate 6, the tensile force can be monitored by the digital display force gauge 14. The tensile force value is the peeling force strength of the release film. After the release film is pasted, a suitable clamping allowance can be left at the end of the membrane plate 6 near the center point of the support frame 2. Subsequently, the push rod of the electric telescopic rod 11 can be extended to drive the rotating frame 9 to rotate, so as to adjust the clamping angle of the rotating frame 9, thereby testing the force when the membrane plate 6 is peeled off from different angles for data comparison.
[0028] Example 2
[0029] See Figure 3 and Figure 4Furthermore, based on Embodiment 1, the membrane plate 6 is provided with a mica electric heating plate 18 inside, and a battery box 7 is provided at the top of the support frame 2 near the fixed frame. The battery box 7 is electrically connected to the mica electric heating plate 18 and the electric telescopic rod 4. A rotary motor 17 is installed at the top of the support platform 1 through a support plate. The drive shaft of the rotary motor 17 is meshed with the rotating rod of the rotating plate 3 through a transmission gear set 16. The transmission gear set 16 consists of a driving gear and a driven gear. The driving gear is connected to the drive shaft of the rotary motor 17, and the driven gear is connected to the rotating rod of the rotating plate 3.
[0030] Specifically, after the release film on one of the membrane plates 6 is peeled off, the rotating plate 3 can be rotated again by the drive shaft of the rotary motor 17, so as to move the other transmission gear set 16 to the rotating frame 9 for the next test. During the test, the personnel can put the peeled release film into the external waste recycling bin and take a new release film to stick on the membrane plate 6. The membrane plate 6 is equipped with a mica electric heating plate 18. During use, the peel strength of the release film when it is pasted on the surface of an object at different temperatures can be tested by heating the mica electric heating plate 18. The use is highly flexible.
[0031] In actual operation, the step of leaving a clamping allowance after the release film is pasted will not be repeated here. Multiple film plates 6 are set to paste the release film. The film plates 6 are clamped on the fixing frame by insert blocks. At the same time, the sides of the film plates 6 are restricted by anti-detachment push plates 5 to improve the fixing stability of the film plates 6 and reduce the probability of displacement of the film plates 6 when pulled. Multiple film plates 6 are installed on the rotating plate 3, and the rotating plate 3 is rotatably installed on the support frame 2. Thus, the rotary motor 17 can be started as needed to drive the rotating plate 3 to rotate, so as to move the film plates 6 to the electric telescopic rod 11 and the rotating frame 9.
[0032] Then, the personnel can activate the electric telescopic rod 12, which drives the movable clamping plate 13 to descend, thus clamping the release film. Afterwards, the push rod of the electric telescopic rod 15 can be controlled to retract, so as to drive the rotating frame 9 to move away from the film plate 6, thereby tearing off the release film pasted on the film plate 6. When the release film is completely peeled off from the film plate 6, the tensile force can be monitored by the digital display force gauge 14. The tensile force value is the peeling force strength of the release film.
[0033] Furthermore, when applying the release film, a suitable clamping allowance can be left at the end of the film plate 6 near the center point of the support frame 2. Subsequently, the rotating frame 9 can be rotated by extending the push rod of the electric telescopic rod 2 11 to adjust the clamping angle of the rotating frame 9, thereby testing the force when the film plate 6 is pulled off from different angles for data comparison. Moreover, the rotating frame 9 can be adjusted to different positions by extending the push rod of the electric telescopic rod 4 15 to test the peeling force of the release film when pulled from front to back.
[0034] After the release film on one of the membrane plates 6 is torn off, the rotating plate 3 can be rotated again by the drive shaft of the rotary motor 17, so as to move the other transmission gear set 16 to the rotating frame 9 for the next test. During the test, the personnel can put the torn release film into the external waste recycling box and take a new release film to stick on the peeled membrane plate 6.
[0035] Furthermore, the interior of the membrane plate 6 is equipped with a mica electric heating plate 18. During use, the peel strength of the release film when it is pasted on the surface of an object at different temperatures can be tested by heating the mica electric heating plate 18 with electricity, which provides high flexibility in use.
[0036] Furthermore, the display and control components and modules used in the aforementioned mica electric heating plate 18, rotary motor 17, electric telescopic rod three 12, electric telescopic rod one 4, digital display force gauge 14, electric telescopic rod four 15, and electric telescopic rod two 11 are all existing technologies, which can be fully implemented by those skilled in the art. The power supply is also common knowledge in the field and needs no further explanation. The content protected by this utility model does not involve any improvement to the software and methods.
[0037] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to the embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
