Problems solved by technology

[0005] Aiming at the problems existing in the prior art, the purpose of the present invention is to provide a novel mobile phone display screen pressure detector, which can force the entire surface of the mobile phone display screen to be subjected to force during the pressure test through the setting of the force conversion capsule. It is transformed into multi-point force, which makes the partial pressure on the surface of the mobile phone display screen uneven. Compared with the whole surface force, the multi-point force test is more suitable for the broken part of the mobile phone display due to local uneven force during use. In addition, the test res

Embodiment 1

[0040] see figure 1 , a in the figure represents a mobile phone display, a new type of mobile phone display pressure detector, including a base 1, the upper left end of the base 1 is fixedly connected with a main rod 2, and the upper end of the main rod 2 is fixedly connected with a main control box 3, the main control box The lower end of 3 is equipped with a detection head, and the upper right end of the base 1 is fixedly connected with a detection table 4, and the detection table 4 is located directly below the detection head, and the display screen of the mobile phone is placed on the detection table 4. The detection head includes an electric motor fixedly connected with the main control box 3 The push rod 6 and the lower end of the electric push rod 6 are fixedly connected with a pressure sensor 7, and the lower end of the pressure sensor 7 is fixedly connected with a powerful conversion bag 5, and the movable sleeve at the outer end of the electric push rod 6 is provided ...

Embodiment 2

[0047] The conversion ball 53 includes a plurality of power conversion balls of different sizes, and maintains no less than 3 power conversion balls with different diameters. The basic structure of the power conversion ball is consistent with Embodiment 1, and the difference is that the center of gravity is controlled 104 is replaced by a magnetorheological fluid, and the hollow hard ball 102 is changed to an elastic material. An electromagnet is installed in the detection table 4, and a high-intensity magnetic field is applied to the magnetorheological fluid through the electromagnet to "harden" it, and then apply a magnetic field to the screen. Pressure, and the applied intensity is different, the "hardness" of the force-transformed ball will also change accordingly, and the screen can be detected more diversely. The concept of "multi-point" has been upgraded to "multi-face", which can imitate fingers of different sizes to exert pressure on the screen to further improve the d...

Abstract

The invention discloses a novel mobile phone display screen pressure-bearing detector, and belongs to the field of pressure-bearing detection equipment. The detector can convert the whole surface stress of a mobile phone display screen into multi-point stress during a pressure-bearing test through the arrangement of a force conversion bag, so as to enable the surface local bearing force of a cellphone display screen to be non-uniform; compared with whole-surface stress, multi-point stress detection is more suitable for the situation that the mobile phone display screen is broken due to unevenlocal stress in the using process, then the reference degree of the detection result for fragile improvement of the mobile phone display screen is higher, and in the testing process, a force conversion bag completely wraps the mobile phone display screen, the stability of the mobile phone display screen during stress is improved, the probability that the mobile phone display screen is broken in advance during testing is reduced, meanwhile, under the interaction of the multiple force conversion point balls and the inner limiting layer, the stability of multiple stress points on the mobile phonedisplay screen can be improved, and the probability that the mobile phone display screen lags behind to be broken during testing is reduced; and the precision of a test result is significantly improved.

Description

technical field [0001] The invention relates to the field of pressure detection equipment, and more specifically relates to a novel mobile phone display pressure detector. Background technique [0002] The display screen of the mobile phone is the screen of the mobile phone, which is used to display images and colors. The screen size is calculated according to the diagonal of the screen, usually in inches, which refers to the length of the diagonal of the screen. Screen material introduction With the gradual popularity of mobile phone color screens, the material of mobile phone screens is becoming more and more important. The color screens of mobile phones vary due to the quality of the LCD and the R&D technology. The types generally include TFT, TFD, UFB, STN and OLED. Generally speaking, the more colors that can be displayed, the more complex images can be displayed, and the layers of the picture will be richer. According to the material of the screen, the current mains...
