Description

Technical Field

[0001] The utility model belongs to the technical field of mobile phone screen processing, and more specifically, particularly relates to a pressure testing device for a liquid crystal display glass structure of a mobile phone screen. Background Art

[0002] With the development of electronic technology, mobile phones have become the most popular electronic products in people's daily lives. At the same time, with the advancement of technology, most mobile phones on the market now use full or large-area LCD touch screens. The glass cover inside the display is an important component for protecting the display. The quality of the glass determines the pressure resistance of the mobile phone. Its performance can be tested by pressure testing the glass.

[0003] Based on the above, the inventors have discovered the following problems: most traditional pressure testing devices place the product to be tested on a testing table, and then perform a pressure test by pressing down. Due to the size differences of mobile phone screens, the position where pressure measurement is required is prone to deviation. When the pressure measurement position is offset, it is easy to cause deviations in the pressure measurement results.

[0004] Therefore, in view of this, the existing structure and deficiencies are studied and improved, and a pressure testing device for the liquid crystal display glass structure of a mobile phone screen is provided, in order to achieve a purpose with greater practical value. Utility Model Content

[0007] Furthermore, the clamping assembly includes a mounting seat installed on the top of the turntable, a semicircular plate is installed on the top of the mounting seat, a fixed plate is installed on the top of the semicircular plate, and a clamping seat is slidably installed on the top of the fixed plate.

[0008] Furthermore, the bottom of the clamping seat is provided with an assembly groove matching the fixing plate.

[0009] Furthermore, a motor is installed on the side wall of the semicircular plate, an output end of the motor passes through one side of the semicircular plate and extends to the other side, and a connecting plate is installed through a fixing frame.

[0010] Furthermore, a connecting panel is installed on the bottom end surface of the outer walls on both sides of the clamping seat, and an arc-shaped connecting shaft is rotatably installed on the other end of the connecting panel, and the other end of the arc-shaped connecting shaft is connected to the connecting plate.

[0011] Furthermore, the sliding assembly includes a slide rail seat installed on the side wall of the "L"-shaped bracket, a slide rail bar is installed on the surface of the slide rail seat, and an "L"-shaped connecting seat is slidably installed on the slide rail seat through the slide rail bar. The top of the "L"-shaped connecting seat is connected to the output end of the electric cylinder, and the bottom end surface of the "L"-shaped connecting seat is connected to the pressure detection probe.

[0012] Compared with the prior art, the utility model has the following beneficial effects:

[0013] 1. The motor, connecting plate, clamping seat, arc-shaped connecting shaft and connecting panel are used together. When the motor is in working state, it can drive the connecting plate to rotate, and arc-shaped connecting shafts are installed at both ends of the connecting plate through shaft pins.
