[0022] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments.

[0023] Example: Reference Figure 1-5 The wear resistance detection device of a mobile phone tempered film shown in the figure comprises a support base 1, a first electric push rod 2 is arranged on the support base 1, a fixing plate 3 is fixedly installed on the output end of the first electric push rod 2, a support plate 4 is arranged above the fixing plate 3, a first carrier plate 5 is arranged above the support plate 4, and a plurality of elastic components are arranged between the carrier plate 4 and the first carrier plate 5, two second electric push rods 6 are arranged on the support base 1, a second carrier plate 7 is fixedly installed on the output end of the two second electric push rods 6, a plurality of pillars 8 are fixed to the bottom of the second carrier plate 7, the plurality of pillars 8 are arranged in a linear arrangement, and a carrier block 9 is fixed to the bottom end of the pillar 8, an auxiliary plate 10 is fixedly sleeved on the outside of the pillar 8, two first bolts 11 are threadedly connected on the auxiliary plate 10, the two first bolts 11 are used to fix sandpaper on the carrier block 9, and the two first bolts 11 are symmetrically arranged about the pillar 8, and a plurality of elastic components are used to adjust the pressure between the mobile phone tempered film and the sandpaper, and two clamping components are arranged on the first carrier plate 5, and the two clamping components are used to fix the mobile phone tempered film on the first carrier plate 5.

[0024] Use a wrench to tighten the two first bolts 11 on the same auxiliary plate 10, so that the two first bolts 11 can fix the sandpaper attached to the surface of the carrier block 9. The multiple carrier blocks 9 are arranged linearly and can carry sandpaper of different mesh sizes. The first electric push rod 2 can be used to push the tempered film of the mobile phone to move up. With the help of the elastic component, the pressure between the tempered film of the mobile phone and the sandpaper can be adjusted, so that the sandpaper can produce different degrees of friction with the tempered film of the mobile phone under the traction of the two second electric push rods 6, so as to better simulate the usage status of the tempered film of the mobile phone in the real environment.

[0025] A pressure sensor 12 is disposed between the fixing plate 3 and the supporting plate 4 , a controller 13 is disposed on the supporting seat 1 , and the pressure sensor 12 is electrically connected to the controller 13 .

[0026] With the help of the pressure sensor 12 and the controller 13, the first electric push rod 2 can be better controlled to adjust the pressure between the sandpaper and the tempered film of the mobile phone.

[0027] Among them, the elastic component includes a spring 14, a limiting rod 15 and a limiting cylinder 16. The spring 14 is fixedly installed between the support plate 4 and the first carrier plate 5. The top of the limiting rod 15 is fixedly installed on the first carrier plate 5. The bottom of the limiting cylinder 16 is fixedly installed on the support plate 4. The bottom end of the limiting rod 15 slides with the inner wall of the limiting cylinder 16, and the spring 14 is sleeved on the outside of the limiting cylinder 16.

[0028] The first electric push rod 2 is used to push the tempered film of the mobile phone clamped by the two clamping components upward. After the tempered film of the mobile phone contacts the sandpaper, the continued extension of the first electric push rod 2 will force the spring 14 to compress, so that the pressure between the sandpaper and the tempered film of the mobile phone changes to meet the detection requirements.

[0029] Among them, the clamping assembly includes an L-shaped plate 17, which is fixedly installed on the first carrier plate 5. A second bolt 18 is threadedly connected to the L-shaped plate 17. The bottom end of the second bolt 18 is rotatably connected to a clamping plate 19 through a bearing. Two guide rods 20 are fixed to the upper surface of the clamping plate 19. The two guide rods 20 are arranged on both sides of the second bolt 18. A through hole for the guide rod 20 to slide is opened on the L-shaped plate 17.

[0030] Use a wrench to tighten the second bolt 18 so that the second bolt 18 pushes the clamping plate 19 downward. With the cooperation between the clamping plate 19 and the first carrier plate 5, the tempered glass film of the mobile phone placed on the first carrier plate 5 can be firmly clamped to prevent the tempered glass film of the mobile phone from shifting during the wear resistance test.

[0031] How this utility works:

[0032] When in use, place the tempered film of the mobile phone on the first carrier plate 5, use a wrench to screw the two second bolts 18 in sequence, so that the second bolts 18 push the clamping plate 19 downward, and with the help of the clamping plate 19 cooperating with the first carrier plate 5, the tempered film of the mobile phone can be clamped, take out the sandpaper, first place one end of the sandpaper under one of the first bolts 11 on the auxiliary plate 10, use a wrench to screw the first bolt 11 to fix one end of the sandpaper, then pull the other end of the sandpaper to make the sandpaper pass through the bottom of the carrier block 9 and move to the bottom of another first bolt 11 on the same auxiliary plate 10, tighten the sandpaper, and use a wrench to screw the first bolt 11 to complete the fixation of the two ends of the sandpaper, so that the sandpaper is close to the carrier block 9. In this way, sandpapers of different mesh sizes can be fixed on multiple carrier blocks 9 in sequence;

[0033] The first electric push rod 2 is controlled to push the tempered film of the mobile phone upward, so that the tempered film of the mobile phone contacts with the sandpaper. As the first electric push rod 2 continues to extend, the spring 14 is compressed, and the pressure between the sandpaper and the tempered film of the mobile phone changes. The pressure is given to the pressure sensor 12, and the pressure sensor 12 will transmit the signal to the controller 13. With the help of the controller 13, the staff can basically obtain the pressure between the sandpaper and the tempered film of the mobile phone. When the pressure reaches a predetermined value, the operation of the first electric push rod 2 is stopped, and the two second electric push rods 6 are controlled to pull the sandpaper back and forth on the tempered film of the mobile phone. After a period of time, the operation of the second electric push rods 6 is stopped, and the first electric push rod 2 can be controlled to move downward to separate the tempered film of the mobile phone from the sandpaper, and the tempered film of the mobile phone is removed. The transmittance of the friction point of the tempered film of the mobile phone can be detected by a transmittance tester, so as to roughly judge the wear resistance of the tempered film of the mobile phone.
