Description
Technical Field
[0001] The present invention relates to the technical field of liquid crystal display screen detection, and in particular to a liquid crystal display screen detection device and method. Background Art
[0002] At the end of the thin-film transistor liquid crystal display (TFT-LCD) manufacturing process, quality inspection is an indispensable process as a key step to ensure product quality before it leaves the factory. Currently, the industry generally uses surface defect screening technology based on machine vision. However, due to the inherent limitations of this inspection solution, there are still two major technical bottlenecks that need to be overcome: First, optical defect recognition is limited in scope. Traditional image acquisition systems utilize fixed-angle light sources and camera configurations, making it difficult to effectively capture display anomalies that are only visible at specific angles of incidence (such as light leakage at certain viewing angles and localized dark spots caused by microcracks). The existence of these blind spots increases the risk of misjudgment and compromises the reliability of defect screening.
[0003] Second, there are inconsistencies in the post-aging cleaning process. After high-temperature, high-humidity aging testing, micron-sized particles are prone to accumulating in the panel's frame area. Existing processes rely on manual tapping to remove foreign matter, but this suffers from technical flaws such as unstable force control and uncontrollable vibration direction. Even more problematic, physical vibration can easily cause loosened impurities to fall into unsanitary corners such as frame seams, causing secondary contamination and posing quality risks to subsequent precision assembly.
[0004] The above problems highlight the technical shortcomings of the existing detection system in multi-dimensional defect characterization and intelligent cleaning. To address the above problems, the present invention document proposes a liquid crystal display detection device and method. Summary of the Invention
[0005] The purpose of the present invention is to solve the problem that in the prior art, the surface of a thin-film transistor liquid crystal display is often inspected by image recognition. However, during the inspection process, due to the fixed angle of image recognition, quality problems such as light leakage and black spots that can only be seen at specified angles are difficult to detect, affecting the inspection results. Moreover, during the aging process of the thin-film transistor liquid crystal display, a large amount of impurities will adhere to its surface. If these impurities are not cleaned, it will affect the inspection results. In the prior art, impurities inside the frame are often removed by manual patting, but it is difficult to control the strength, and the impurities removed easily fall into the gap of the bottom frame, making it inconvenient for subsequent cleaning.

[0015] The method for using the liquid crystal display screen detection device includes the following steps: S1. The plywood is driven to move by retracting the cylinder, so that the plywood is combined to position the thin-film transistor liquid crystal display. The first motor then drives the first gear and the second gear to transmit. The second gear drives the feed tray to rotate through the bearing. The feed tray drives the displacement assembly to rotate, so that the thin-film transistor liquid crystal display rotates accordingly. S2. When the thin-film transistor liquid crystal display screen corresponds to the bidirectional nozzle, the electric push rod pushes the vibrator to move horizontally, and the dust removal operation is performed through the external dust removal equipment, and the vibration head is dusted. The vibrator moves horizontally to drive one end of the inclined plate away from the first piston rod. At this time, the third spring drives the second piston rod and the elastic component to retract, the two bidirectional nozzles are separated, and the travel wheel moves to the lower surface of the inclined plate. At this time, the fourth spring drives the bidirectional nozzle to retract, so that the vibration head smoothly contacts the thin-film transistor liquid crystal display screen.

After the dust is removed, the impurity removal component is retracted and reset, and the inclined plate squeezes the first piston rod, which drives the second piston rod through hydraulic pressure to reset the elastic component, so that the two-way nozzle is merged; S4. After the dust removal is completed, the thin film transistor liquid crystal display screen turns to the monitoring probe position, and the pulley is squeezed by the cam to produce displacement, so that the support rod drives the sleeve plate and the annular frame to move, and the annular frame drives the protrusion to correspond to the roller. At this time, the driving component drives the steering component to rotate, so that the detection angle adjustment component and the thin film transistor liquid crystal display screen rotate, and the roller rotates through each protrusion and is squeezed to move, so that the extension rod drives the support bar and the slide rod to move, and the gear rod and the fifth gear reciprocate, and then drives the clamping component and the thin film transistor liquid crystal display screen to swing, adjust and rotate through the adjustment part, so that the thin film transistor liquid crystal display screen is inspected by the monitoring probe. After the inspection, it is switched to the initial position for unloading, and the thin film transistor liquid crystal display screen is reassembled to continue a new round of inspection operations.
[0016] Compared with the prior art, the present invention provides a liquid crystal display screen detection device and method, which has the following beneficial effects: 1. This LCD inspection device and method rotates a pulley to the convex surface of a cam, causing the displacement assembly to drive the bump to correspond to the roller through a ring frame. The driving assembly then drives the steering assembly and the detection angle adjustment assembly to rotate, causing the detection angle adjustment assembly to move around the bump and reciprocate to generate extrusion, thereby causing the thin-film transistor liquid crystal display to swing. Inspection operations at different angles can be performed using a monitoring probe, increasing the inspection surface of the thin-film transistor liquid crystal display, thereby ensuring the reliability of defect screening for thin-film transistor liquid crystal displays.
[0017] 2. The LCD screen detection device and method are configured to place an impurity removal component close to the thin film transistor liquid crystal display screen, and simultaneously connect a two-way nozzle through an external dust removal device to pre-clean the screen surface and the vibration head corresponding to the vibration head. Furthermore, the piston component drives the elastic component to retract, so that the two-way nozzles are separated and retracted, so that the vibration head contacts the thin film transistor liquid crystal display screen. At this time, the thin film transistor liquid crystal display screen is vibrated by the vibrator and the vibration head, and then the fixed nozzle is used to perform dust removal to avoid the problem of secondary pollution caused by residual impurities.
[0018] 3. The LCD detection device and method uses a bidirectional nozzle to pre-dust the vibration head and the thin-film transistor liquid crystal display, and then uses the impurity removal component to vibrate the thin-film transistor liquid crystal display to remove dust again, and cooperates with the fixed nozzle to perform dust suction operations. At the same time, the driving component drives the steering component to rotate, so that the steering component drives the detection angle adjustment component and the clamping component to rotate, so that the thin-film transistor liquid crystal display rotates, and cooperates with the vibration to achieve a more significant dust removal effect, effectively remove impurities, avoid quality risks in the subsequent precision assembly of the thin-film transistor liquid crystal display, and reduce the subsequent rework time. After pre-dust removal, impurities are avoided from adhering to the vibration head and the thin-film transistor liquid crystal display area corresponding to the vibration head, which may cause scratches on the thin-film transistor liquid crystal display during the vibration process.
