Description

Technical Field

[0001] This utility model relates to the field of mobile phone tempered glass screen protector performance testing technology, and in particular to a device for simulating and testing the impact resistance performance of protective films. Background Technology

[0002] With the widespread use of smartphones, screen protectors, especially tempered glass screen protectors, have become an important accessory for protecting phone screens from scratches, impacts, and other damage. Tempered glass screen protectors, with their high hardness, good light transmission, and certain impact resistance, have become the first choice for consumers to protect their phone screens. Most curved screen phones use multi-layer anti-scratch and impact-resistant curved screen protectors.

[0003] After tempered glass screen protectors are processed, their impact resistance is tested. Currently used testing equipment usually relies on a vertical rod to impact the tempered glass screen protector to complete the test. However, the vertical rod used for impact is also easy to loosen and fall when the tempered glass screen protector is placed. Moreover, if the tempered glass screen protector breaks during the test, fragments may fly out and cause injury to the test personnel. Utility Model Content

[0004] This invention provides a protective film impact resistance simulation testing device, which can prevent the impact rod from hitting the tester's hand when handling tempered glass film, and can also shield the fragments even if the tempered glass film breaks during the test to avoid injury to the tester.

[0005] In a first aspect, this utility model provides a protective film impact resistance simulation testing device, specifically comprising: a base; four multi-section electric cylinders symmetrically mounted on the top of the base, a test tray fixed at the top of the four multi-section electric cylinders, a tempered film adhesive block fixed at the middle position of the top of the test tray, and two shields slidably mounted on the top of the test tray; two guide plates symmetrically fixed on the rear side of the top of the base; and an impact rod bracket fixed at the middle position of the rear side of the top of the base, with an impact rod slidably mounted on the impact rod bracket.

[0006] When the test tray is moved to the top, the two shields will stick together tightly, and at this time the bottom end of the impact rod can contact the top surface of the tempered glass film adhesive block.

[0007] The shield has a raised strip on the bottom of both the front and rear sides, and the test tray also has a corresponding strip-shaped guide groove on the top front and rear sides.

[0008] The impact rod is also equipped with a circular protrusion that can fit tightly against the top surface of the impact rod bracket. When the test plate moves down to the bottom, the two shields will separate, and at this time the bottom of the impact rod will detach from the tempered glass film adhesive block.

[0009] Each guide plate has a bending groove in front of it, and a round rod is fixed to the rear side of each shield. The rear end of the round rod on the rear side of the shield is slidably installed in the bending groove in front of the guide plate.

[0010] Each of the shields has a glass observation window on its front outer wall and a semi-circular opening in the middle of the top side of each shield.

[0011] The tempered glass film adhesive block has curved surfaces on its top left and right sides corresponding to the tempered glass film, and the impact rod is located above the middle position of the tempered glass film adhesive block.

[0012] This invention provides a device for simulating and testing the impact resistance of protective films, which has the following advantages:

[0013] The shielding cover in this invention can slide left and right. When the tempered glass film is picked up or put down, the two shielding covers will automatically separate. At this time, the impact rod used for impact will also stay above and will not fall down, so as to avoid the impact rod hitting the tester's hand. After the test tray and tempered glass film move up, the shielding cover can cover the tempered glass film on the top of the tempered glass film adhesive block. In this way, even if the tempered glass film breaks during the test, the fragments can be covered to avoid injury to the tester. Attached Figure Description

[0025] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of this utility model. Based on the described embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

[0026] Example 1: Please refer to Figures 1 to 6 :

[0027] This invention proposes a protective film impact resistance simulation testing device, comprising: a base 1; four multi-section electric cylinders 2 symmetrically mounted on the top of the base 1, a test tray 3 fixed to the top of the four multi-section electric cylinders 2, a tempered glass film adhesive block 4 fixed at the top center of the test tray 3, and two shielding covers 5 slidably mounted on the top of the test tray 3. The base 1 supports the upper part of the device structure. The multi-section electric cylinders 2 can adjust the height of the test tray 3 when they extend and retract. The test tray 3 supports the tempered glass film adhesive block 4 and the shielding covers 5. The tempered glass film adhesive block 4 supports the tempered glass film to be tested. During testing, even if the tempered glass film breaks and scatters fragments, the shielding covers 5 will block them, preventing damage. The tester was injured; two guide plates 6 are symmetrically fixed on the top rear side of the base 1. When the test tray 3 moves up and down, the shield 5 will also move up and down synchronously. During this process, the round rod on the rear side of the shield 5 will also slide in the bending groove in front of the guide plate 6, thus driving the shield 5 to slide left and right; an impact rod bracket 7 is fixed in the middle of the top rear side of the base 1, and an impact rod 8 is slidably installed on the impact rod bracket 7. During the test, the impact rod 8 can be pulled up to the test height by the pull ring at the top of the impact rod 8 and then released. At this time, the impact rod 8 will fall quickly under the support of the impact rod bracket 7 and hit the tempered film surface. If the tempered film is intact, it means that the impact resistance performance is qualified. If the tempered film is broken, it means that the impact resistance performance is unqualified.

[0028] In this embodiment, as Figure 1 and Figure 2As shown, when the test tray 3 moves to the top, the two shields 5 will stick together tightly, and at this time the bottom end of the impact rod 8 can contact the top surface of the tempered glass film adhesive block 4. During the upward movement of the shields 5, the round rod on its rear side will also slide upward in the bending groove in front of the guide plate 6, eventually causing the two shields 5 to stick together tightly and wrap the tempered glass film adhesive block 4 inside. Then the impact resistance test can be carried out through the impact rod 8.

[0029] In this embodiment, as Figures 1-4 and Figure 6 As shown, a raised strip is provided on the bottom of the front and rear sides of the shield 5, and a corresponding strip guide groove is provided on the top front and rear sides of the test tray 3. When the shield 5 slides left and right, the raised strip on the bottom of its front and rear sides will also slide left and right in the strip guide groove on the top front and rear sides of the test tray 3, thereby ensuring the stability of the shield 5 when it slides and preventing the shield 5 from shaking up and down.

[0030] In this embodiment, as Figures 1-4 As shown, the impact rod 8 is also equipped with a circular protrusion that can fit tightly against the top surface of the impact rod bracket 7. When the test tray 3 moves down to the bottom, the two shields 5 will separate, and at this time the bottom of the impact rod 8 will detach from the tempered glass film adhesive block 4. The circular protrusion on the impact rod 8 can limit its movement and prevent it from sliding down too much. Moreover, when the test tray 3 moves down to the bottom, it is also convenient to pick up and put down the tempered glass film on the top of the tempered glass film adhesive block 4.

[0031] In this embodiment, as Figures 1-6 As shown, each guide plate 6 has a bending groove in front, and each shield 5 has a round rod fixed to its rear side. The rear end of the round rod on the rear side of the shield 5 is slidably installed in the bending groove in front of the guide plate 6. When the test plate 3 moves up and down, the shield 5 will also move up and down synchronously. During this process, the round rod on the rear side of the shield 5 will also slide in the bending groove in front of the guide plate 6, thus driving the shield 5 to slide left and right.

[0032] In this embodiment, as Figure 2 and Figure 4 As shown, the top left and right sides of the tempered glass film adhesive block 4 are provided with curved surfaces corresponding to the tempered glass film. The impact rod 8 is located above the middle position of the tempered glass film adhesive block 4. During the test, the tempered glass film to be tested can be pasted on the top of the tempered glass film adhesive block 4, and it can be ensured that the impact rod 8 can impact the tempered glass film on the top of the tempered glass film adhesive block 4.

[0033] Example 2, based on Example 1, such as Figures 1-6As shown, each of the front outer walls of the shield 5 is provided with a glass observation window, and each of the shield 5 has a semi-circular opening in the middle of the top side. When the impact resistance of the tempered film is tested by the impact rod 8, the condition of the tempered film can be observed through the glass observation window on the front outer wall of the shield 5, and the semi-circular opening in the middle of the top of the shield 5 can facilitate the sliding of the impact rod 8 up and down.

[0034] The working principle of this embodiment is as follows: During installation, the device can be supported and fixed on the workbench by the base 1, and the multi-section electric cylinders 2 are connected to the external power supply and controller. When it is necessary to test the impact resistance of the tempered glass screen protector, first control the four multi-section electric cylinders 2 to retract and drive the test tray 3 to move down to the bottom. During this process, the shielding cover 5 will also move down synchronously. As the shielding cover 5 moves down, the round rod on its rear side will also slide down in the bending groove in front of the guide plate 6. Therefore, the two shielding covers 5 can slide and separate to the left and right sides respectively. Then, the tempered glass screen protector to be tested can be pasted on the top of the tempered glass screen protector pasting block 4. Then, control the four multi-section electric cylinders 2 to extend and push the test tray 3 onto the test tray 3. As the shielding cover 5 moves to the top, it also moves upwards simultaneously. During this process, the round rod on the rear side of the shielding cover 5 slides upwards in the bending groove in front of the guide plate 6. Eventually, the two shielding covers 5 will stick together tightly and wrap the tempered glass film adhesive block 4 inside. Then, the shock rod 8 can be pulled up to the test height by the pull ring at the top and released. At this time, the shock rod 8 will fall rapidly under the support of the shock rod bracket 7 and impact the surface of the tempered glass film. If the tempered glass film is intact, it means that the impact resistance performance is qualified. If the tempered glass film is broken, it means that the impact resistance performance is unqualified. Moreover, even if the tempered glass film is broken, the fragments will be blocked by the shielding cover 5 to avoid injury to the test personnel.
