DETAILED DESCRIPTION

[0025] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0026] A display screen hardness testing platform comprises a base 1, a support plate 2 is arranged on the upper side of the base 1, a mounting frame 3 fixed to the upper end of the base 1 is arranged on the outer side of the support plate 2, a display screen that needs to be hardness tested is placed on the support plate 2, a limiting plate 21 is fixed on the upper end of the support plate 2, and when the display screen is placed on the support plate 2, the display screen is supported by the limiting plate 21.

[0027] In this embodiment, please refer to Figure 1 and Figure 3 A hydraulic telescopic rod 7 is fixed to the upper end of the base 1, and a mounting frame 72 is fixed to the output end of the hydraulic telescopic rod 7. A pressing roller 71 is rotatably connected to the inner side of the mounting frame 72. When the hydraulic telescopic rod 7 is started, the pressing roller 71 can be driven to rise and fall. When the pressing roller 71 descends, the display screen is pressed by the pressing roller 71 to perform a hardness test on the display screen.

[0028] Furthermore, two groups of telescopic sleeves 8 are provided on the outside of the hydraulic telescopic rod 7, one end of the telescopic sleeve 8 is fixed to the upper end of the mounting frame 3, and the other end is fixed to the mounting frame 72. When the mounting frame 72 is raised or lowered, the telescopic sleeve 8 can be synchronously extended and retracted, thereby reducing the force load on the hydraulic telescopic rod 7.

[0029] For further examples, see Figure 1 and Figure 2 Two groups of clamping plates 4 are arranged on the outer side of the support plate 2, and the display screen on the limiting plate 21 is clamped and fixed by the clamping plates 4, and an adjusting component 5 is arranged on the lower side of the clamping plates 4, and the adjusting component 5 is connected to the support plate 2, and the movement of the clamping plates 4 can be adjusted by the adjusting component 5.

[0030] Specifically, the clamping plate 4 is composed of a movable frame 41, a positioning plate 42 and an anti-skid pad 43. The movable frames 41 are respectively located on both sides of the support plate 2, the positioning plate 42 is fixed to the upper end of the movable frame 41, and the anti-skid pad 43 is pasted on the positioning plate 42 near the limit plate 21. The mobilization component 5 is composed of an electric telescopic rod 51 and a connecting frame 52. The electric telescopic rod 51 is fixed to the inside of the support plate 2, and the connecting frame 52 is fixed to the output end of the electric telescopic rod 51. At the same time, a fixed fixed to the support plate 2 is provided above the mobilization component 5. The fixed frame 23 is slidably connected to the inside of the limiting cavity 411, so that the fixed frame 23 limits the movement of the movable frame 41 through the connection with the limiting cavity 411. When the electric telescopic rod 51 is extended, the rotation of the movable frame 41 drives the positioning plate 42 to approach the limiting plate 21, thereby clamping the display screen. When the electric telescopic rod 51 is retracted, the rotation of the movable frame 41 drives the positioning plate 42 away from the display screen, and no longer clamps the display screen.

[0031] In a further embodiment, a slide plate 22 is fixed to the lower end of the support plate 2, so that the base 1 can be translated on the base 1 through the slide plate 22, and an adjustment component is installed inside the base 1, which can drive the support plate 2 to translate as a whole.

[0032] Specifically, the adjustment component consists of a drive motor 6 and a rotating rod 61. The drive motor 6 is installed inside the base 1. The rotating rod 61 is rotatably connected to the inside of the base 1, and the rotating rod 61 is connected to the output shaft of the drive motor 6. The specific connection method can adopt the existing technology. At the same time, the rotating rod 61 is threadedly connected to the skateboard 22, and two groups of fixed rods 11 are arranged on the outside of the hydraulic telescopic rod 7. The fixed rods 11 are fixed to the inside of the support plate 2 and pass through the inside of the skateboard 22. The movement of the skateboard 22 is limited and supported by the fixed rods 11. When the drive motor 6 is started to drive the rotating rod 61 to rotate, the skateboard 22 can drive the support plate 2 to translate as a whole.

[0033] When performing hardness testing on a display screen, the display screen to be tested is placed on the limit plate 21, the electric telescopic rod 51 is started to extend outward, and the positioning plate 42 is driven to clamp and fix the display screen by the rotation of the movable frames 41 on both sides. After the position of the display screen is fixed, the drive motor 6 is started to drive the rotating rod 61 to rotate, so that the support plate 2 drives the position of the display screen to translate. At this time, the hydraulic telescopic rod 7 is started to drive the pressing roller 71 to descend. During the translation process of the display screen, the hardness test of the display screen is completed through the pressing of the pressing roller 71.
