[0002] The glass safety film is a material widely used in the fields of architecture, automobiles, solar photovoltaics, etc. It has good safety performance and can prevent the fragments from splashing and causing harm after the glass is broken. In order to ensure the quality of the glass safety film, strict scratch-resistant tests need to be carried out on it.

It is impossible to controllably change the test force of the glass safety film. Therefore, the test range is small, the test efficiency is not high, and it is difficult to simulate the scratch-resistant performance of the glass safety film when it is pasted on a glass with a curvature.

Specific implementation manner

[0021] An embodiment of the present utility model provides a glass safety film scratch resistance test device, as Figures 1 - 3 shown, including the first limiting cylinder 11, the first cavity 12, the second limiting cylinder 13, the second cavity 14, the electromagnet 15, the first platform 16, the second platform 17, the first spring 18, the test groove 20, the limiting boss 21, the first slot 22, the second slot 23, the third slot 24, the fourth slot 25, the first slider 26, the fifth slot 27, the first sliding rod 30, the third cavity 31, the second spring 32, the second sliding rod 33, the blade 34, the screw base 35, the motor 36, the screw 37, the second slider 38, and the third slider 39.

[0022] As Figures 1 - 2 shown, a first cavity 12 is opened in the first limiting cylinder 11, a second cavity 14 is opened in the second limiting cylinder 13, a limiting boss 21 is provided at one end of the first limiting cylinder 11 close to the second limiting cylinder 13, a test groove 20 is provided at one end of the second limiting cylinder 13 close to the first limiting cylinder 11, a first platform 16 is slidably connected in the first cavity 12, a driving assembly is fixedly arranged on the first platform 16, a third slot 24 is opened on the first platform 16, a scratching assembly is slidably connected to the third slot 24, and the driving assembly is used to drive the scratching assembly to slide. A second platform 17 is fixedly connected to one side of the first cavity 12 close to the limiting boss 21, a first spring 18 is fixedly connected to the second platform 17, and the first spring 18 is fixedly connected to the first platform 16.

[0023] It should be noted that the first platform 16 is made of a cobalt-nickel-iron alloy, the limiting boss 21 has a spherical arc surface, the shape and size of the test groove 20 are adapted to those of the limiting boss 21, an electromagnet 15 is fixedly arranged in the second cavity 14, the electromagnet 15 is used to drive the first platform 16 to slide in the first cavity 12, a fifth slot 27 is formed on the outer circumferential surface of the first platform 16, and a first slider 26 is fixedly arranged on the outer side wall of the first cavity 12, and the first slider 26 is slidably connected with the fifth slot 27.

[0024] The scratching assembly includes a first sliding rod 30 and a second sliding rod 33. The first sliding rod 30 is slidably connected with the third slot 24. A third cavity 31 is formed in the first sliding rod 30. A second spring 32 is arranged in the third cavity 31. One end of the second spring 32 is fixedly connected to the third cavity 31, and the other end of the second spring 32 is fixedly connected to the second sliding rod 33. A blade 34 is fixedly connected to the end of the second sliding rod 33 away from the second spring 32.

[0025] The horizontal height of the first platform 16 can be changed by changing the magnetic force of the electromagnet 15, so as to change the distance between the first sliding rod 30 and the limiting boss 21, resulting in a change in the degree to which the second sliding rod 33 compresses the second spring 32. Therefore, the elastic force of the second spring 32 on the second sliding rod 33 changes, thereby changing the pressure of the blade 34 on the second sliding rod 33 against the glass safety film in the test groove 20, achieving the purpose of changing the scratching force.

[0026] It should be noted that a first slot 22 is formed on the limiting boss 21, the width of the first slot 22 is adapted to the width of the blade 34, a second slot 23 is formed on the second platform 17, and the width of the second slot 23 is adapted to the width of the first sliding rod 30.

[0027] The driving assembly includes two screw bases 35, a motor 36 and a screw 37. The screw bases 35 are fixedly connected to both ends of the third slot 24. The motor 36 is fixedly connected to the screw base 35. The output shaft of the motor 36 is fixedly connected to the screw 37. A second slider 38 is threadedly connected to the screw 37.

[0028] When conducting the scratch resistance test on the glass safety film in this solution, first, attach the glass safety film to the test groove 20, align the limiting boss 21 with the test groove 20, and make the limiting boss 21 fit with the test groove 20. Then, start the electromagnet 15. The electromagnet 15 drives the first platform 16 to slide in the direction of the second slot 23 through magnetic force. The first platform 16 compresses the first spring 18, and the first spring 18 generates an elastic force on the second slot 23, causing the second slot 23 to drive the first limiting cylinder 11 to make the limiting boss 21 closely adhere to the test groove 20.

[0029] Then, start the motor 36. The output shaft of the motor 36 drives the screw 37 to rotate. The screw 37 drives the second slider 38 to reciprocate along the fourth slot 25 through the thread. The second slider 38 drives the first sliding rod 30 to slide along the third slot 24. The first sliding rod 30 drives the blade 34 to slide along the first slot 22 through the second sliding rod 33. When the end of the blade 34 far from the second sliding rod 33 slides on the test groove 20, the horizontal height of the blade 34 changes with the arc of the test groove 20 while changing the elastic potential energy of the second spring 32.

[0030] Finally, turn off the electromagnet 15 and the motor 36, separate the first limiting cylinder 11 from the second limiting cylinder 13, and detect the scratch degree of the glass safety film on the test groove 20.
