Description

Technical Field

[0001] The present invention belongs to the technical field of liquid crystal display processing, and particularly relates to a fixing device for liquid crystal display processing. Background Art

[0002] A liquid crystal display (LCD) is a flat panel display that uses liquid crystal materials to change the arrangement state under the action of an electric field to achieve image display. Due to its unique advantages, such as low power consumption, small size, low radiation, rich colors, etc., liquid crystal displays have been widely used in various fields. The working principle of a liquid crystal display is mainly based on the optical properties of liquid crystal materials. Liquid crystal materials are substances between solid and liquid states, with a unique molecular arrangement. When an electric field acts on liquid crystal materials, the arrangement of their molecules changes, thereby affecting the transmission and deflection of light. By controlling the change of the electric field, precise control of the light transmittance of liquid crystal materials can be achieved, thereby displaying different images. When processing a liquid crystal display, it needs to be fixed.

[0003] Publication (Announcement) No. CN220603802U discloses a fixing device for liquid crystal display processing. This utility model discloses a fixing device for liquid crystal display processing, belonging to the field of liquid crystal display processing, including a fixing table. 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 provided clamping and fixing mechanism is used in cooperation 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. The driving motor is started, and the output end drives the first rotating rod 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 moving process, the included angle formed between the symmetrical connecting rods is forced to gradually become smaller, so as to drive the symmetrical second concave blocks to make relative movement along the T-shaped track strip, thereby driving the fixed clamping plate to make synchronous relative movement on the top surface of the fixing table through the movable block, so as to centeringly clamp and fix the liquid crystal display body between the fixed clamping plates.

[0004] However, the problems existing in this prior art are as follows: First, every time a liquid crystal screen of a different size is replaced, the working parameters of the motor need to be changed accordingly, such as the number of turns of rotation, which is not conducive to improving work efficiency;

[0005] Second, a liquid crystal display usually has four sides, but this prior art can only fix two sides of the liquid crystal display, and it is difficult to determine the positions of the other two sides. Summary of the Invention

[0006] In view of the problems existing in the prior art, the present invention provides a fixing device for processing liquid crystal display screens, which has the advantage of being convenient to accurately fix liquid crystal display screens of different sizes in the middle, and solves the problems of the prior art.

[0007] The present invention is realized as follows: A fixing device for processing liquid crystal display screens includes a base platform. Two symmetrically arranged first sliding grooves are provided on the base platform. A first slider is slidably connected to the first sliding groove, and the upper side of the first slider is fixedly connected to a first clamping rod. It also includes a housing. A motor is fixedly connected to the lower side of the housing. The output shaft of the motor is fixedly connected to a lead screw through a coupling. A nut sleeve is connected to the lead screw. The edge of the nut sleeve is rotatably connected to a first connecting rod. The upper end of the first connecting rod is rotatably connected to the lower side of the first slider. Two symmetrically arranged second sliding grooves are provided on the base platform. A second slider is slidably connected to the second sliding groove, and the upper side of the second slider is fixedly connected to a second clamping rod. The edge of the nut sleeve is rotatably connected to a second connecting rod. The upper end of the second connecting rod is rotatably connected to the lower side of the second slider. Both the first connecting rod and the second connecting rod are elastic telescopic rods.

[0008] Preferably, the first connecting rod includes: a first sub-rod, a second sub-rod, a first connecting block, a second connecting block, and a spring. The first sub-rod is rotatably connected to the lower side of the first slider. The second sub-rod is rotatably connected to the edge of the nut sleeve. The first connecting block is connected to the end of the first sub-rod away from the first slider. The second connecting block is connected to the end of the second sub-rod away from the nut sleeve. One end of the spring is fixedly connected to the first connecting block, and the other end of the spring is fixedly connected to the second connecting block.

[0009] Preferably, the first connecting block is fixedly connected to the first sub-rod, and the second connecting block is fixedly connected to the second sub-rod.

[0010] Preferably, a first screw rod is fixedly connected to the end of the first connecting block. The first screw rod is rotationally connected to the first sub-rod through a thread. A second screw rod is fixedly connected to the end of the second connecting block. The second screw rod is rotationally connected to the second sub-rod through a thread. The thread directions of the first screw rod and the second screw rod are opposite.

[0011] Preferably, the second connecting rod has the same structure as the first connecting rod.

[0012] Preferably, a third sliding groove is provided on the first sub-rod; a fourth sliding groove is provided on the second sub-rod; the first connecting rod further includes a limiting sliding plate. Two limiting sliders are fixedly connected to the limiting sliding plate, and the two limiting sliders are respectively slidably connected to the third sliding groove and the fourth sliding groove.

[0013] Preferably, an elastic bearing member is fixedly connected to the limit sliding plate. When the first clamping rod and / or the second clamping rod do not clamp the liquid crystal display screen, the elastic bearing member can extend to the upper side of the base through the first slideway or the second slideway; when the first clamping rod and / or the second clamping rod approach each other to clamp the liquid crystal display screen, the upper surface of the elastic bearing member is not higher than the upper surface of the base.

[0014] Preferably, the elastic bearing member includes an airbag and an air pump. The airbag is fixedly connected to the limit sliding plate, and the air pump is communicated with the airbag.

[0015] Preferably, an elastic detection member is provided in the spring, and the elastic detection member is signal-connected to the motor.

[0016] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0017] First, the liquid crystal display screen to be processed is placed stably on the base. The base provides a stable working platform for the liquid crystal display screen to ensure its stability during the processing. Subsequently, the motor is started. The motor converts the rotational motion of the lead screw into the linear downward motion of the nut sleeve. This mechanical transmission method has the advantages of high precision and high stability, and can ensure the position accuracy of the nut sleeve during the downward movement. When the nut sleeve descends, it drives two first clamping rods to approach each other through two first connecting rods. The function of the first clamping rod is to clamp both sides of the liquid crystal display screen to ensure its stability in the horizontal direction. At the same time, the nut sleeve also drives two second clamping rods to approach each other through two second connecting rods. The function of the second clamping rod is to clamp the other two sides of the liquid crystal display screen, so as to fix the four sides of the liquid crystal display screen. Through the above settings, the liquid crystal display screen can be accurately fixed in the center of the base. This fixing method not only ensures the position accuracy of the liquid crystal display screen, but also provides stable support for its subsequent processing.

[0018] Both the first connecting rod and the second connecting rod are elastic telescopic rods. This design takes into account the possible slight differences in the size of the liquid crystal display screen. Even if the size of the liquid crystal display screen increases by 5 mm and the number of turns of the motor rotation remains unchanged, the elastic telescopic rod can play a buffering role. If the size of the liquid crystal display screen increases and the nut sleeve continues to descend, the elastic telescopic rod will be stretched instead of forcing the first clamping rod or the second clamping rod to continue approaching. In this way, even if the size of the liquid crystal display screen increases, it will not be crushed due to excessive clamping force. Description of the Drawings

[0026] In order to further understand the invention content, characteristics and effects of the present invention, the following embodiments are cited and detailed as follows in conjunction with the drawings.

[0027] The structure of the present invention will be described in detail below with reference to the drawings.

[0028] Refer to Figures 1-6, a fixing device for liquid crystal display processing provided by an embodiment of the present invention includes a base 1. Two symmetrically arranged first slideways 2 are provided on the base 1. A first slider 3 is slidably connected to the first slideway 2. The upper side of the first slider 3 is fixedly connected to a first clamping rod 4. It further includes a housing 5. A motor 6 is fixedly connected to the lower side of the housing 5. The output shaft of the motor 6 is fixedly connected to a lead screw 7 through a coupling. A nut sleeve 8 is connected to the lead screw 7. The edge of the nut sleeve 8 is rotatably connected to a first connecting rod 9. The upper end of the first connecting rod 9 is rotatably connected to the lower side of the first slider 3. Two symmetrically arranged second slideways 10 are provided on the base 1. A second slider 11 is slidably connected to the second slideway 10. The upper side of the second slider 11 is fixedly connected to a second clamping rod 12. The edge of the nut sleeve 8 is rotatably connected to a second connecting rod 13. The upper end of the second connecting rod 13 is rotatably connected to the lower side of the second slider 11. Both the first connecting rod 9 and the second connecting rod 13 are elastic telescopic rods.

[0029] During use, place the liquid crystal display to be processed on the base 1. Then the motor 6 drives the nut sleeve 8 to descend through the lead screw 7. The nut sleeve 8 drives the two first clamping rods 4 to approach each other through the two first connecting rods 9, thereby clamping both sides of the liquid crystal display. At the same time, the nut 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 liquid crystal display. Through this setting, on the one hand, the liquid crystal display can be accurately fixed in the middle. On the other hand, since both the first connecting rod 9 and the second connecting rod 13 are elastic telescopic rods, assuming the size of the liquid crystal display increases by 5 mm and the number of rotations of the motor 6 remains unchanged (the descending distance of the nut sleeve 8 remains unchanged), when the first clamping rod 4 or the second clamping rod 12 clamps the liquid crystal display, if the nut sleeve 8 continues to descend, it will pull the first connecting rod 9 and the second connecting rod 13 to become longer, rather than the two first clamping rods 4 or the two second clamping rods 12 continuing to approach and damaging the liquid crystal display.

[0030] Moreover, since the aspect ratios of different liquid crystal displays are different, the first clamping rod 4 and the second clamping rod 12 do not always clamp the liquid crystal display at the same time. By setting the first connecting rod 9 and the second connecting rod 13 as elastic telescopic rods, when a set of clamping rods clamps the liquid crystal display, the other set of clamping rods can still be lowered through the descent of the nut sleeve 8, so as to clamp liquid crystal displays with different aspect ratios, thus facilitating processing.

[0031] Refer to Figures 3-5, the first connecting rod 9 includes: 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 one end of the first sub-rod 91 away from the first slider 3; the second connecting block 94 is connected to one 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 setting, the spring 95 can be stretched or compressed, so that the first connecting rod 9 realizes the function of elastic expansion and contraction.

[0032] Regarding the connection method of the first connecting block 93 and the second connecting block 94, there are two implementation manners:

[0033] In one implementation manner, 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.

[0034] In another implementation manner, a first screw rod 96 is fixedly connected to the end of the first connecting block 93, and the first screw rod 96 is rotationally connected to the first sub-rod 91 by threads; a second screw rod 97 is fixedly connected to the end of the second connecting block 94, and the second screw rod 97 is rotationally connected to the second sub-rod 92 by threads; the thread directions of the first screw rod 96 and the second screw rod 97 are opposite. 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 directions of the first screw rod 96 and the second screw rod 97 are opposite, they can be screwed into or out of the first sub-rod 91 and the second sub-rod 92 simultaneously and respectively. The greater the lengths that 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 greater the length of the entire first connecting rod 9, and vice versa. For example, for a larger liquid crystal display screen, the length of the first connecting rod 9 can be adjusted to be larger, so that the distance between the two first clamping rods 4 is greater, and a larger liquid crystal display screen can be carried.

[0035] Furthermore, the structure of the second connecting rod 13 is the same as that of the first connecting rod 9.

[0036] Refer to Figures 1-6, a third slideway 14 is provided on the first sub-rod 91; a fourth slideway 15 is provided on the second sub-rod 92; the first connecting rod 9 further includes a limit slide plate 98, and two limit sliders 99 are fixedly connected to the limit slide plate 98, and the two limit sliders 99 are respectively slidably connected to the third slideway 14 and the fourth slideway 15.

[0037] The limit slide plate 98 and the limit sliders 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 setting, the stability of the device can be improved.

[0038] Refer to Figures 1-6 , an elastic bearing member 16 is fixedly connected to the limit slide plate 98. When the first clamping rod 4 and / or the second clamping rod 12 do not clamp the liquid crystal display screen, the elastic bearing member 16 can extend to the upper side of the base 1 through the first slideway 2 or the second slideway 10; when the first clamping rod 4 and / or the second clamping rod 12 approach each other to clamp the liquid crystal display screen, the upper surface of the elastic bearing member 16 is not higher than the upper surface of the base 1.

[0039] Through this setting, when the liquid crystal display 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 lead screw 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 liquid crystal display screen is placed on the base 1, the elastic bearing member 16 contacts the liquid crystal display screen first, which can play an elastic support role, thereby preventing the liquid crystal display screen and the base 1 from colliding violently. When the motor 6 drives the nut sleeve 8 to descend, on the one hand, it can drive the first clamping rod 4 and the second clamping rod 12 to approach each other to clamp the liquid crystal display screen, and on the other hand, it can drive the elastic bearing member 16 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 lead screw 7 is lowered), so as to slowly lower the liquid crystal display screen.

[0040] Moreover, through this setting, during the processing of the liquid crystal display screen, the elastic bearing member 16 can tightly hold the liquid crystal display screen. And 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 jack up the liquid crystal display screen.

[0041] 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 limit slide plate 98, and the air pump is in communication with the airbag. The air pump can adjust the gas level of the airbag, so that the airbag can be used more flexibly. For example, when some liquid crystal display screens are placed on the base 1, one side is higher and the other side is lower. Then, the airbag can be supported by adjusting the gas volume of the airbag to make it reach a horizontal state, and then the liquid crystal display screen can be clamped by the first clamping rod 4, which is convenient for processing.

[0042] Refer to Figure 6 , an elastic detection member 17 is provided in the spring 95, and the elastic detection member 17 is signal-connected to the motor 6. After the liquid crystal display 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 received by the spring 95 exceeds a preset value, on the one hand, it will cause damage to the liquid crystal display screen, and on the other hand, it will also damage the spring 95. In this solution, the elastic detection member 17 can detect the tensile elastic force received by the spring 95, and when it reaches the preset value, it controls the motor 6 to stop rotating.

[0043] The elastic detection member 17 is a device or equipment that can monitor and measure the elastic force of the spring 95 in real time. Structurally, it includes the following key parts:

[0044] Sensor: Responsible for converting the elastic force change of the spring 95 into a measurable electrical signal. Common sensor types include strain gauges, pressure sensors, etc. They can accurately capture the minute deformation of the spring 95 and convert it into an electrical signal output.

[0045] Data acquisition system: Responsible for receiving the electrical signals output by the sensor and performing processing and analysis. The data acquisition system usually includes circuit modules such as amplifiers, filters, and analog-to-digital converters to ensure the accuracy and stability of the signals.

[0046] Display and recording device: Used to display the elastic force change of the spring 95 in real time and can record the data for subsequent analysis, such as devices like computers, monitors, printers, etc.

[0047] The working principle of the real-time detection member 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 an elastic force. The sensor measures the deformation amount or stress change of the spring 95 and converts it into an electrical signal output. The data acquisition system receives these electrical signals, performs processing and analysis, and finally obtains the real-time elastic force data of the spring 95.

[0048] In practical applications, the elastic force real-time detection member of the spring 95 has the following advantages:

[0049] 1. Real-time monitoring: It can monitor the elastic force change of the spring 95 in real time, promptly detect abnormal situations, and ensure structural safety.

[0050] 2. Precise measurement: By adopting high-precision sensors and data acquisition systems, it can accurately measure the elastic force of the spring 95 and improve the measurement accuracy.

[0051] 3. Automation and intelligence: By combining computer technology and data analysis methods, it can realize the automated processing and intelligent analysis of the elastic force data of the spring 95, and improve work efficiency.

[0052] The working principle of the present invention:

[0053] During use, the liquid crystal display to be processed is placed on the base 1, and then the motor 6 drives the nut 8 to descend through the lead screw 7. The nut 8 drives the two first clamping rods 4 to approach each other through the two first connecting rods 9, thereby clamping both sides of the liquid crystal display; at the same time, the nut 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 liquid crystal display. On the one hand, the liquid crystal display can be accurately fixed in the middle. On the other hand, since both the first connecting rod 9 and the second connecting rod 13 are elastic telescopic rods, therefore, assuming that the size of the liquid crystal display increases by 5 mm 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 liquid crystal display, if the nut 8 continues to descend, it will pull the first connecting rod 9 and the second connecting rod 13 to become longer, rather than the two first clamping rods 4 or the two second clamping rods 12 continuing to approach and causing the liquid crystal display to be damaged.

[0054] It should be noted that in this article, relational terms such as first and second are only used to distinguish one entity or operation from another entity or operation, and do not necessarily require or imply any such actual relationship or order between these entities or operations.
