Description

A fixing device for processing liquid crystal display screen

Technical Field

The invention belongs to the technical field of liquid crystal display screen processing, and in particular relates to a fixing device for processing a liquid crystal display screen.

Background Art

Liquid Crystal Display is a flat-panel display that uses liquid crystal materials to change their arrangement state under the action of an electric field to display images. Liquid crystal displays have been widely used in various fields due to their unique advantages, such as low power consumption, small size, low radiation, and rich colors. The working principle of liquid crystal displays is mainly based on the optical properties of liquid crystal materials. Liquid crystal material is a substance between solid and liquid, with a unique molecular arrangement. When an electric field acts on the liquid crystal material, its molecular arrangement changes, thereby affecting the transmission and deflection of light. By controlling the change in the electric field, the light transmittance of the liquid crystal material can be precisely controlled, thereby displaying different images. When processing the liquid crystal display, it needs to be fixed.

The bottom surface of the fixing table is fixedly connected with a support frame, and the top surface of the fixing table is provided with a liquid crystal display body. The clamping and fixing mechanism is used in conjunction with the liquid crystal display body. Before processing the liquid crystal display body, the liquid crystal display body is placed on the top surface of the fixing table, and the driving output end of the driving motor is turned on to drive the adjusting screw to rotate through the first rotating rod, so that the adjusting block moves downward along the adjusting screw through the threaded hole on the top surface, and during the movement, the angle formed between the symmetrical connecting rods is forced to gradually decrease, so as to drive the symmetrical second concave blocks to perform relative movement operations along the T-shaped track strips, thereby driving the fixed clamping plates to perform synchronous relative movement operations on the top surface of the fixing table through the movable blocks, so as to center and clamp the liquid crystal display body between the fixed clamping plates.

However, the problems of the prior art are: first, each time a different size of LCD screen is replaced, the working parameters of the motor, such as the number of rotations, need to be changed accordingly, which is not conducive to improving work efficiency;

As a preferred embodiment of the present invention, the end of the first connecting block is fixedly connected to a first screw, and the first screw is connected to the first sub-rod by threaded rotation; the end of the second connecting block is fixedly connected to a second screw, and the second screw is connected to the second sub-rod by threaded rotation; the thread rotation directions of the first screw and the second screw are opposite.

Compared with the prior art, the present invention has the following beneficial effects:

First, the LCD screen to be processed is placed steadily on the base. The base provides a stable working platform for the LCD screen to ensure its stability during the processing. Then, the motor is started. The motor converts the rotational motion of the screw into the linear downward motion of the screw sleeve through the rotational motion of the screw rod. This mechanical transmission method has the advantages of high precision and high stability, and can ensure the position accuracy of the screw sleeve during the descent process. When the screw sleeve descends, the two first connecting rods drive the two first clamping rods to approach each other. The function of the first clamping rod is to clamp the two sides of the LCD screen to ensure its stability in the horizontal direction. At the same time, the screw sleeve also drives the two second clamping rods to approach each other through the two second connecting rods. The function of the second clamping rod is to clamp the other two sides of the LCD screen, thereby fixing the four sides of the LCD screen. Through the above settings, the LCD screen can be accurately fixed in the middle of the base. This fixing method not only ensures the position accuracy of the LCD screen, but also provides stable support for its subsequent processing.

The first connecting rod and the second connecting rod are both elastic telescopic rods. This design takes into account the possible slight differences in the size of the LCD screen. Even if the size of the LCD screen increases by 5 mm, while the number of turns of the motor remains unchanged, the elastic telescopic rod can still play a buffering role. If the size of the LCD screen increases and the screw sleeve continues to descend, the elastic telescopic rod will be stretched instead of forcing the first clamping rod or the second clamping rod to move closer. In this way, even if the size of the LCD screen increases, it will not be crushed due to excessive clamping force.

DETAILED DESCRIPTION

In order to further understand the content, features and effects of the present invention, the following embodiments are given as examples and described in detail with reference to the accompanying drawings.

The structure of the present invention is described in detail below in conjunction with the accompanying drawings.

1 to 6, an embodiment of the present invention provides a fixing device for processing a liquid crystal display screen, comprising a base 1, wherein the base 1 is provided with two symmetrically arranged first slideways 2, wherein the first slideways 2 are slidably connected to a first slider 3, and the upper side of the first slider 3 is fixedly connected to a first clamping rod 4; further comprising a shell 5, wherein a motor 6 is fixedly connected to the lower side of the shell 5, and the output shaft of the motor 6 is fixedly connected to a screw rod 7 through a coupling, wherein a screw sleeve 8 is connected to the screw rod 7, and the edge of the screw sleeve 8 is rotatably connected to a first connecting rod 9, and the upper end of the first connecting rod 9 is rotatably connected to the lower side of the first slider 3; wherein the base 1 is provided with two symmetrically arranged second slideways 10, wherein the second slideways 10 are slidably connected to a second slider 11, and the upper side of the second slider 11 is fixedly connected to a second clamping rod 12, and the edge of the screw sleeve 8 is rotatably connected to a second connecting rod 13, and the upper end of the second connecting rod 13 is rotatably connected to the lower side of the second slider 11; the first connecting rod 9 and the second connecting rod 13 are both elastic telescopic rods.

When in use, the LCD screen to be processed is placed on the base 1, and then the motor 6 drives the screw sleeve 8 to descend through the screw rod 7, and the screw sleeve 8 drives the two first clamping rods 4 to approach each other through the two first connecting rods 9, thereby clamping the two sides of the LCD screen; at the same time, the screw sleeve 8 also drives the two second clamping rods 12 to approach each other through the two second connecting rods 13, thereby clamping the other two sides of the LCD screen. Through this setting, on the one hand, the LCD screen can be accurately fixed in the middle, and on the other hand, since the first connecting rod 9 and the second connecting rod 13 are both elastic telescopic rods, therefore, assuming that the size of the LCD screen increases by 5mm, and the number of turns of the motor 6 remains unchanged (the distance of the screw sleeve 8 descending remains unchanged), when the first clamping rod 4 or the second clamping rod 12 clamps the LCD screen, if the screw sleeve 8 continues to descend, it will pull the first connecting rod 9 and the second connecting rod 13 to lengthen, rather than the two first clamping rods 4 or the two second clamping rods 12 continue to approach each other to crush the LCD screen.

Furthermore, since different LCD screens have different length-to-width ratios, the first clamping rod 4 and the second clamping rod 12 do not always clamp the LCD screen at the same time. By configuring the first connecting rod 9 and the second connecting rod 13 as elastic telescopic rods, when one set of clamping rods clamps the LCD screen, the other set of clamping rods can still be lowered by lowering the screw sleeve 8, thereby achieving clamping of LCD screens with different length-to-width ratios, thereby facilitating processing.

Referring to Fig. 3 to Fig. 5, the first connecting rod 9 comprises: a first sub-rod 91, a second sub-rod 92, a first connecting block 93, a second connecting block 94, and a spring 95; the first sub-rod 91 is rotatably connected to the lower side of the first slider 3; the second sub-rod 92 is rotatably connected to the edge of the screw sleeve 8; the first connecting block 93 is connected to an end of the first sub-rod 91 away from the first slider 3; the second connecting block 94 is connected to an end of the second sub-rod 92 away from the screw sleeve 8; one end of the spring 95 is fixedly connected to the first connecting block 93, and the other end of the spring 95 is fixedly connected to the second connecting block 94. Through this arrangement, the spring 95 can be stretched or compressed, so that the first connecting rod 9 can achieve the function of elastic expansion and contraction.

There are two implementations for connecting the first connection block 93 and the second connection block 94:

In one embodiment, the first connecting block 93 is fixedly connected to the first sub-rod 91 , and the second connecting block 94 is fixedly connected to the second sub-rod 92 .

In another embodiment, the end of the first connecting block 93 is fixedly connected with a first screw rod 96, and the first screw rod 96 is connected to the first sub-rod 91 by thread rotation; the end of the second connecting block 94 is fixedly connected with a second screw rod 97, and the second screw rod 97 is connected to the second sub-rod 92 by thread rotation; the first screw rod 96 and the second screw rod 97 have opposite thread rotation directions. In this setting, the first connecting block 93 itself is not directly connected to the first sub-rod 91, but is threadedly connected to the first sub-rod 91 through the first screw rod 96. Similarly, the second connecting block 94 itself is not directly connected to the second sub-rod 92, but is threadedly connected to the second sub-rod 92 through the second screw rod 97. Through this setting, the initial length of the first connecting rod 9 can be adjusted. The specific principle is as follows: by manually rotating the spring 95, the first screw rod 96 and the second screw rod 97 can be driven to rotate. Since the thread rotation directions of the first screw rod 96 and the second screw rod 97 are opposite, the first sub-rod 91 and the second sub-rod 92 can be screwed in or out at the same time. The longer the first screw rod 96 and the second screw rod 97 are screwed out of the first sub-rod 91 and the second sub-rod 92, the longer the length of the entire first connecting rod 9 is, and vice versa. For example, for a larger LCD screen, the length of the first connecting rod 9 can be increased, so that the distance between the two first clamping rods 4 is larger, and the larger LCD screen can be carried.

Furthermore, the second connecting rod 13 and the first connecting rod 9 have the same structure.

Referring to Figures 1 to 6, a third slide 14 is provided on the first sub-rod 91; a fourth slide 15 is provided on the second sub-rod 92; the first connecting rod 9 also includes a limiting slide 98, and two limiting sliders 99 are fixedly connected to the limiting slide 98, and the two limiting sliders 99 are slidably connected to the third slide 14 and the fourth slide 15 respectively.

The limiting slide plate 98 and the limiting slider 99 can slide and limit the first sub-rod 91 and the second sub-rod 92 without affecting the elastic expansion and contraction of the spring 95, and can prevent the first sub-rod 91 and the second sub-rod 92 from bending at the position of the spring 95. Through this arrangement, the stability of the device can be improved.

Referring to Figures 1 to 6, an elastic supporting component 16 is fixedly connected to the limiting slide plate 98. When the first clamping rod 4 and/or the second clamping rod 12 do not clamp the LCD screen, the elastic supporting component 16 can extend to the upper side of the base 1 through the first slide 2 or the second slide 10; when the first clamping rod 4 and/or the second clamping rod 12 are close to each other to clamp the LCD screen, the upper surface of the elastic supporting component 16 is not higher than the upper surface of the base 1.

With this arrangement, when the LCD screen is not clamped, the distance between the two first clamping rods 4 is relatively far, and the end of the first connecting rod 9 close to the screw rod 7 is relatively high. At this time, the upper end of the elastic bearing member 16 extends to the upper side of the base 1 through the first slideway 2. When the LCD screen is placed on the base 1, the elastic bearing member 16 first contacts the LCD screen, which can play a role of elastic support, thereby preventing the LCD screen and the base 1 from colliding violently. When the motor 6 drives the screw sleeve 8 to descend, on the one hand, the first clamping rod 4 and the second clamping rod 12 can be driven to approach each other to clamp the LCD screen, and on the other hand, the elastic bearing member 16 can be driven to descend to the lower side of the base 1 or flush with the base 1 (because the end of the first connecting rod 9 close to the screw rod 7 is lowered), thereby slowly lowering the LCD screen.

Furthermore, through this arrangement, during the processing of the LCD screen, the elastic bearing member 16 can be tightened against the LCD screen. After the processing is completed, when the first clamping rod 4 and/or the second clamping rod 12 move away from each other and release the elastic bearing member 16, the elastic bearing member 16 can lift up the LCD screen.

Preferably, the elastic bearing member 16 includes an airbag and an air pump (not shown in the figure), the airbag is fixedly connected to the limiting slide plate 98, and the air pump is connected to the airbag. The air pump can adjust the air level of the airbag, so that the airbag can be used more flexibly. For example, some LCD screens are higher on one side and lower on the other side when placed on the base 1. The LCD screen can be supported by adjusting the air volume of the airbag to reach a horizontal state, and then the LCD screen is clamped by the first clamping rod 4, which is convenient for processing.

Referring to Fig. 6, the spring 95 is provided with an elastic detection member 17, and the elastic detection member 17 is connected to the motor 6 by signal. After the LCD screen is clamped by the first clamping rod 4, if the screw sleeve 8 continues to descend, the spring 95 will be stretched. If the elastic tension of the spring 95 exceeds a preset value, on the one hand, the LCD screen will be damaged, and on the other hand, the spring 95 will also be damaged. In this solution, the elastic detection member 17 can detect the tensile elastic force of the spring 95, and when the preset value is reached, the motor 6 is controlled to stop rotating.

The elasticity detection member 17 is a device or equipment capable of real-time monitoring and measuring the elastic force of the spring 95. Structurally, it includes the following key parts:

Sensor: responsible for converting the change in the elastic force of the spring 95 into a measurable electrical signal. Common sensor types include strain gauges, pressure sensors, etc., which can accurately capture the tiny deformation of the spring 95 and convert it into an electrical signal output.

Data acquisition system: responsible for receiving the electrical signals output by the sensor, and processing and analyzing them. The data acquisition system usually includes circuit modules such as amplifiers, filters, analog-to-digital converters, etc. to ensure the accuracy and stability of the signal.

Display and recording device: used to display the change of the elastic force of the spring 95 in real time and record the data for subsequent analysis, such as a computer, a display, a printer and other equipment.

The working principle of the real-time detection element is mainly based on the mechanical properties of the spring 95 and the measurement principle of the sensor. When the spring 95 is subjected to an external force, it will deform and generate elastic force. The sensor measures the deformation or stress change of the spring 95 and converts it into an electrical signal output. The data acquisition system receives these electrical signals, processes and analyzes them, and finally obtains the real-time elastic force data of the spring 95.

In practical applications, the real-time detection element of the elastic force of spring 95 has the following advantages:

1. Real-time monitoring: It can monitor the elastic force changes of the spring 95 in real time, detect abnormal conditions in time, and ensure the safety of the structure.

2. Accurate measurement: The use of high-precision sensors and data acquisition systems can accurately measure the elastic force of the spring 95 and improve the accuracy of the measurement.

3. Automation and intelligence: Combining computer technology and data analysis methods, the automatic processing and intelligent analysis of spring 95 elastic force data can be realized to improve work efficiency.

Working principle of the present invention:

When in use, the LCD screen to be processed is placed on the base 1, and then the motor 6 drives the screw sleeve 8 to descend through the screw rod 7, and the screw sleeve 8 drives the two first clamping rods 4 to approach each other through the two first connecting rods 9, thereby clamping the two sides of the LCD screen; at the same time, the screw sleeve 8 also drives the two second clamping rods 12 to approach each other through the two second connecting rods 13, thereby clamping the other two sides of the LCD screen. On the one hand, the LCD screen can be accurately fixed in the middle, and on the other hand, since the first connecting rod 9 and the second connecting rod 13 are both elastic telescopic rods, therefore, assuming that the size of the LCD screen increases by 5mm, and the number of turns of the motor 6 remains unchanged, when the first clamping rod 4 or the second clamping rod 12 clamps the LCD screen, if the screw sleeve 8 continues to descend, it will pull the first connecting rod 9 and the second connecting rod 13 to lengthen, rather than the two first clamping rods 4 or the two second clamping rods 12 continue to approach each other to crush the LCD screen.
