Abstract
Description
Technical Field
[0001] This utility model relates to the field of liquid crystal screen manufacturing technology, and specifically to a correction mechanism for liquid crystal screen panel manufacturing. Background Technology
[0002] In the production process of liquid crystal display panels (LCD or OLED, etc.), the accuracy of material loading is one of the key factors in ensuring the quality of subsequent processing, improving yield, and reducing costs. Therefore, the position of the liquid crystal glass substrate needs to be corrected by a calibration mechanism before loading. However, to solve this technical problem, existing technologies require a four-axis drive structure to achieve precise positioning of the liquid crystal display panel along the X and Y axes. But such drive structures are not only complex and bulky, but also have high manufacturing costs, and can only calibrate one liquid crystal glass substrate at a time, resulting in low calibration efficiency.
[0003] Therefore, the utility model patent with patent publication number CN223117417U discloses a calibration mechanism for LCD screen panel production, which includes a calibration table, a calibration station set on the calibration table, and an X-axis calibration component and a Y-axis calibration component for calibrating the LCD glass substrate at the calibration station, respectively. The X-axis calibration component and the Y-axis calibration component are set below the calibration table and are arranged in a cross shape. Each component includes a guide rail assembly, two main sliders slidably set on the guide rail assembly, a double-ended threaded screw placed parallel to the guide rail assembly for driving the two main sliders to move closer or further away synchronously, a servo motor for driving the double-ended threaded screw to rotate, and an outer calibration column vertically set on the main slider and located around the calibration station. In this utility model, the X-axis calibration component and the Y-axis calibration component can each drive the opposite outer calibration column to move closer or further away through a power source, realizing position calibration. It has the advantages of simple and compact structure and synchronous movement.
[0004] This utility model patent still has some shortcomings. In actual production, it is often necessary to adjust the position of the correction column to adapt to the production of LCD screen panels of different models and sizes. However, adjusting the position of the correction column requires disassembly and reinstallation, which is cumbersome and inefficient. Therefore, this utility model proposes an improved correction mechanism for LCD screen panel production. Summary of the Invention
[0005] This invention provides a correction mechanism for the production of liquid crystal screen panels to solve the problems mentioned in the background art.
[0006] The objective of this utility model is achieved through the following means:
[0007] A correction mechanism for manufacturing LCD screen panels includes a correction platform and an X-axis correction module and a Y-axis correction module arranged crosswise on the correction platform. Each X-axis correction module and Y-axis correction module includes a drive motor, a bidirectional lead screw, and two sets of positioning structures. The two sets of positioning structures are arranged opposite to each other on both sides of the correction platform and connected to the bidirectional lead screw. Each positioning structure includes a correction positioning component, a limiting plate, and a guide slide for connecting to the bidirectional lead screw. The limiting plate is provided with a positioning groove, and the correction positioning component is slidably mounted on the positioning groove.
[0008] Furthermore, a limiting plane is provided on the side of the correction positioning member near the correction platform.
[0009] Furthermore, the X-axis correction module and / or Y-axis correction module also include a reference positioning component disposed in the middle of the correction platform, and the middle of the correction platform is provided with a limiting groove for accommodating the reference positioning component.
[0010] Furthermore, both the corrective positioning element and the reference positioning element are fitted with corresponding elastic layers.
[0011] Furthermore, the bottoms of the corrective positioning component and the reference positioning component are fixedly connected to the positioning slide groove and the limiting slide groove respectively by corresponding screws.
[0012] Furthermore, the correction platform is equipped with up to four adsorption modules.
[0013] Furthermore, a sensor is provided in the middle of the adsorption module.
[0014] This invention uses a drive motor to rotate a bidirectional lead screw, thereby causing two sets of positioning structures to move relative to or away from each other, achieving position correction of the LCD screen panel in the X and Y axes. This structure not only simplifies the drive structure and reduces manufacturing costs but also improves correction efficiency. Simultaneously, the correction module uses a positioning groove to accommodate a sliding correction positioning component, allowing its position to be adjusted without disassembly and reinstallation. This adapts to LCD screen panels of different sizes and models, further improving production efficiency. Attached Figure Description

Detailed Implementation
[0020] The present invention will now be described in further detail with reference to the accompanying drawings and specific embodiments.
[0021] Example 1:
[0022] In this embodiment, refer to Figure 1 - Figure 4 The specific implementation of a correction mechanism for LCD screen panel production includes a correction platform 1 and an X-axis correction module 20 and a Y-axis correction module 30 arranged crosswise on the correction platform 1. The X-axis correction module 20 and the Y-axis correction module 30 each include a drive motor 2, a bidirectional lead screw 3, and two sets of positioning structures. The two sets of positioning structures are arranged opposite to each other on both sides of the correction platform 1 and are connected to the bidirectional lead screw 3. The positioning structure includes a correction positioning component 4, a limiting plate 5, and a guide slide 6 for connecting with the bidirectional lead screw 3. The limiting plate 5 is provided with a positioning groove 501, and the correction positioning component 4 is slidably installed on the positioning groove 501.
[0023] In existing technologies, the limited contact area between the correction column and the LCD screen panel during the correction process can easily lead to excessive local pressure and damage to the LCD screen panel. Therefore, this invention provides a limiting plane 7 on the side of the correction positioning member 4 near the correction platform 1. This limiting plane 7 effectively increases the contact area between the correction positioning member 4 and the LCD screen panel, resulting in a more uniform pressure distribution and thus preventing damage caused by excessive local pressure. Furthermore, the design of the limiting plane 7 also improves correction accuracy, ensuring the stability and accuracy of the LCD screen panel during the correction process.
[0024] In this embodiment, the correction platform 1 is equipped with two adsorption modules 8 for fixing the LCD screen panels. Therefore, only the X-axis correction module 20 is equipped with a reference positioning member 9 located in the middle of the correction platform 1. The middle of the correction platform 1 is equipped with a limiting groove 101 for accommodating the reference positioning member 9, and the reference positioning member 9 is slidably installed in the limiting groove 101. During the correction process, the two sets of reference positioning members 9 respectively provide reference positioning for the two LCD screen panels in the X-axis direction, ensuring their positional accuracy after correction. A sensor 10 is provided in the middle of the adsorption module 8, which is used to detect whether the LCD screen panel falls into the adsorption platform. After the X-axis correction module 20 and the Y-axis correction module 30 complete the correction and positioning of the LCD screen panel, the adsorption module 8 is activated to adsorb and fix the LCD screen panel, thereby preventing the corrected LCD screen panel from shifting or falling off.
[0025] In practice, an external conveying device delivers the LCD screen panel to two adsorption modules 8. When the sensor 10 in the middle of the adsorption module 8 senses the screen, the X-axis correction module 20 and the Y-axis correction module 30 are activated. The drive motor 2 drives the bidirectional lead screw 3 to rotate, thereby causing the two sets of correction and positioning components 4 to move relative to or away from each other, thereby correcting the position of the LCD screen panel in the X-axis and Y-axis directions. After the positioning correction is completed, the adsorption module 8 adsorbs and fixes the LCD screen panel to prevent the LCD screen panel from shifting or falling off.
[0026] The adsorption panel includes an adsorption substrate and multiple adsorption holes disposed on the adsorption substrate. The adsorption holes are evenly distributed to provide a stable adsorption force, ensuring that the LCD screen panel does not wobble during the correction process. Furthermore, the modular and detachable design of the adsorption panel facilitates cleaning or replacement to accommodate different specifications or types of LCD screen panels, improving the flexibility and practicality of the equipment. In specific implementation...
[0027] Both the correction positioning element 4 and the reference positioning element 9 are fitted with corresponding elastic layers 11 to increase the buffering performance during the correction process and protect the LCD screen panel from damage. The elastic layers 11 can be made of soft materials such as rubber or silicone, possessing a certain degree of elasticity and wear resistance, effectively absorbing the impact force during the correction process and improving the correction effect. Simultaneously, the elastic layers 11 also increase the friction between the correction positioning element 4 and the reference positioning element 9 and the LCD screen panel, improving the stability during the correction process.
[0028] The bottoms of the corrective positioning component 4 and the reference positioning component 9 are fixedly connected to the positioning slide groove 501 and the limiting slide groove 101 respectively by corresponding screws, so as to facilitate operation during installation or disassembly. In addition, the design of the corrective positioning component 4 and the reference positioning component 9 takes into account the principle of easy replacement. When the elastic layer 11 is worn or aged, a new elastic layer 11 can be easily replaced to ensure the continuous stability and accuracy of the corrective mechanism.
[0029] This invention uses a drive motor 2 to drive a bidirectional lead screw 3 to rotate, thereby causing two sets of correction and positioning components 4 to move relative to or away from each other, achieving position correction of the LCD screen panel in the X and Y axes. This structure not only simplifies the drive structure and reduces manufacturing costs, but also improves correction efficiency. Simultaneously, the correction module uses a positioning groove 501 to accommodate the slidable correction and positioning components 4, allowing for adjustment of their position without disassembly and reinstallation. This adapts to LCD screen panels of different sizes and models, improving production efficiency.
[0030] Example 2:
[0031] like Figure 5 As shown, the difference between this embodiment and Embodiment 1 is that the correction platform 1 is provided with four adsorption modules 8 for fixing the liquid crystal screen panel.
[0032] In this embodiment, both the X-axis correction module 20 and the Y-axis correction module 30 include a reference positioning component 9 disposed in the middle of the correction platform 1. The middle of the correction platform 1 is provided with a limiting groove 101 for accommodating the reference positioning component 9. The reference positioning component 9 plays a role in fixed-point positioning. When the X-axis correction module 20 and the Y-axis correction module 30 are started, the correction positioning component 4 will drive the LCD screen panel to move towards the reference positioning component 9, thereby realizing the correction and positioning of the LCD screen and completing the correction and positioning of multiple LCD screen panels at the same time, thus improving the correction efficiency.
