Description

Technical Field

[0001] This utility model belongs to the field of liquid crystal display technology, specifically relating to a real-time feedback and early warning device based on the pressing state of a liquid crystal display. Background Technology

[0002] A liquid crystal display (LCD) is a device that uses the optical properties of liquid crystal materials to display images. Its core is to control the arrangement of liquid crystal molecules through an electric field, thereby adjusting the light transmittance. The basic structure of an LCD consists of a backlight layer, a polarizer, a glass substrate, a liquid crystal layer, and a color filter.

[0003] The manufacturing process of a liquid crystal display (LCD) requires lamination, which is one of its core manufacturing steps. The main purpose of lamination is to tightly bond multiple layers (such as glass substrate, liquid crystal layer, polarizer, color filter, etc.) together to ensure the optical performance, structural stability, and functional reliability of the display.

[0004] However, when pressing the LCD display, if the pressing device continues to move downwards when the pressing is relatively tight, and there is no feedback warning device during pressing, the pressing device may easily damage the hydraulic display screen. Utility Model Content

[0022] Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of technical features indicated. Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of that feature. In the description of this utility model, "a plurality of" means two or more, unless otherwise explicitly specified.

[0023] In this utility model, unless otherwise explicitly specified and limited, the terms "installation," "connection," "linking," "fixing," and "equipped with" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model according to the specific circumstances.

[0024] Referring now to the accompanying drawings, the various figures are intended only to illustrate certain exemplary embodiments and are not intended to limit the scope of the invention. In the various figures, the same reference numerals denote the same or corresponding parts. The dimensions and scales in the various figures are also for illustrative purposes only and should not be construed as limiting the scope of the invention; these dimensions may be enlarged relative to actual products.

[0025] Reference Figure 1-4 The present invention relates to a real-time feedback and early warning device based on the pressing state of a liquid crystal display screen, comprising a lower pressing mold structure 1, a housing 2 provided on the outer walls of both sides of the lower pressing mold structure 1, a limiting structure 3 slidably connected inside the housing 2, the number of the limiting structures 3 being set to multiple, a pushing structure 4 provided on the outer walls of both sides of the lower pressing mold structure 1, an upper pressing mold 5 provided on the top of the lower pressing mold structure 1, and insert rods 6 provided at the four corners of the upper pressing mold 5.

[0026] Furthermore, in the above technical solution, the pressing lower mold structure 1 includes a pressing lower mold body 101. Detection holes 102 are provided on both sides of the pressing lower mold body 101. Auxiliary holes 103 are provided on both sides of the pressing lower mold body 101, and the auxiliary holes 103 are connected to the detection holes 102.

The insertion rod 6 at the bottom of the upper pressing mold 5 is inserted into the interior of the auxiliary hole 103 and the position of the insertion rod 6 is detected by the infrared rangefinder 104. When the position of the insertion rod 6 reaches the predetermined position, the insertion rod 6 is limited and the motor is started. The motor drives the synchronous belt drive device 107, the synchronous belt drive device 107 drives the transmission screw 105 to rotate, and the transmission screw 105 drives the push structure 4 to rise and fall.

One end of the sliding shaft 301 is provided with a limiting plate 302. The sliding shaft 301 slides on the inner wall of the housing 2, and the sliding shaft 301 pushes the limiting plate 302 into the inside of the detection hole 102 to limit the insertion rod 6, so as to prevent the upper mold 5 from pressing the liquid crystal display screen too tightly.

[0028] Furthermore, in the above technical solution, the pushing structure 4 includes a lifting bar 401, a mating hole 402 in the middle of the lifting bar 401, and sliding holes 403 on both sides of the lifting bar 401. The mating hole 402 cooperates with the transmission screw 105, and the sliding hole 403 is slidably connected to the sliding rod 106.

A crossbar 405 is provided at one end of the electric telescopic rod 404, and pushing blocks 406 are provided on both sides of the crossbar 405. After the lifting bar 401 is raised to a suitable position, the electric telescopic rod 404 is activated.
