Description

Technical Field

[0001] The utility model relates to the technical field of LCD aging, and more specifically, to a rotary LCD aging device with AOI. Background Art

[0002] The LCD liquid crystal display screen is mainly composed of two parallel glass substrates, with a liquid crystal layer sandwiched in the middle. These liquid crystal molecules will change their arrangement direction under the action of an electric field, thereby controlling the transmission and shielding of light to achieve image display. In addition, it also includes key components such as polarizers and backlight modules; in the LCD liquid crystal display screen, when no electric field is applied, the arrangement of the liquid crystal molecules causes the light to deflect when passing through, and thus is absorbed by the lower polarizer, and the screen appears black or dark. When an electric field is applied, the arrangement of the liquid crystal molecules changes, enabling the light to pass directly, and thus presenting a bright state or corresponding color; in the manufacturing industry of LCD liquid crystal display screens, product quality control is crucial. In order to ensure that the LCD liquid crystal display screens meet the expected performance standards before leaving the factory, all products need to undergo strict aging tests. This test process is not only to verify the stability and reliability of the products, but also to detect and eliminate products with initial defects at an early stage, preventing them from flowing into subsequent production stages or the final market, thereby avoiding unnecessary losses to consumers;

[0003] However, traditional LCD aging devices have significant limitations in terms of detection efficiency and accuracy: these devices usually do not have the function of automatic optical inspection (AOI). Therefore, during the aging process, visual inspection often relies on manual labor, or additional optical instruments are used for inspection after aging. This manual inspection method is not only inefficient but also easily affected by human factors, resulting in a high error rate. Therefore, we have made improvements in this regard and proposed a rotary LCD aging device with AOI. Summary of the Utility Model

Those skilled in the art explicitly and implicitly understand that the embodiments described herein can be combined with other embodiments.

[0027] As described in the background art, traditional LCD aging equipment has significant limitations in terms of detection efficiency and accuracy: these devices usually do not have the automatic optical inspection (AOI) function. Therefore, during the aging process, manual visual inspection is often relied upon, or additional optical instruments are used for inspection after aging. This manual inspection method is not only inefficient but also easily affected by human factors, resulting in a relatively high error rate.

[0028] To solve this technical problem, the present utility model provides a rotary LCD aging device with AOI, which is applied to the aging detection of LCDs.

[0029] Specifically, please refer to Figures 1 - 3 , the rotary LCD aging device with AOI specifically includes:

[0030] A heating box 1, in which a detection mechanism 3 is arranged. The detection mechanism 3 includes a support member arranged in the heating box 1, and an AOI camera 305 is installed on the support member.

[0034] It should be noted that similar reference numerals and letters indicate similar items in the following drawings. Therefore, once an item is defined in one drawing, it does not need to be further defined and explained in subsequent drawings.

[0035] Embodiment 1 of the rotary LCD aging device with AOI of the present utility model

[0036] Please refer to Figures 1 - 3, the rotating LCD aging device with AOI of the present utility model includes: a heating box 1, a detection mechanism 3 is arranged in the heating box 1, the detection mechanism 3 includes a support member arranged in the heating box 1, and an AOI camera 305 is installed on the support member. The AOI camera 305 is used to detect the aging condition of the LCD in the heating box 1. In this application, the set AOI camera 305 can take pictures and monitor the LCD, realizing automatic detection, avoiding the time delay caused by manual detection or using instruments alone, reducing misjudgment caused by human factors by using automatic detection, reducing equipment and labor costs, and improving production efficiency;

[0037] It realizes automatic detection, greatly improves the detection efficiency, avoids the time delay caused by manual detection or using instruments alone, reduces labor costs and time costs. At the same time, automatic detection can ensure the consistency and accuracy of detection, reducing the misjudgment probability caused by human factors. This is because the AOI camera 305 can take pictures and monitor the LCD in real time, without frequent manual intervention, and can continuously and stably carry out detection work, greatly saving the detection time. And through advanced image recognition technology, it can accurately judge the aging condition of the LCD.

[0038] Furthermore, as Figures 1 - 3 shown, the support member includes a rack 301 installed in the heating box 1. A sliding seat 302 is sleeved on the outer surface of the rack 301, and the AOI camera 305 is installed on the sliding seat 302. The rack 301 and the sliding seat 302 provide extremely stable support for the AOI camera 305, ensuring that the position of the AOI camera 305 remains stable during the detection process, which is crucial for improving the detection accuracy and can avoid the situation of image blurring or inaccurate detection caused by the shaking of the AOI camera 305.

[0039] Furthermore, as Figures 1 - 3 shown, a third driving motor 303 is installed on one side of the sliding seat 302. The output shaft of the third driving motor 303 penetrates into the third driving motor 303 and is connected with a driving gear 304. The driving gear 304 meshes with the rack 301. The third driving motor 303 can drive the sliding seat 302 to lift through the driving gear 304 and the rack 301, and then can drive the AOI camera 305 to lift. The height of the AOI camera 305 can be flexibly adjusted according to actual needs, greatly improving the versatility of the equipment and being able to adapt to the detection requirements of different sizes of LCDs. Whether it is a small LCD or a large LCD, the height of the AOI camera 305 can be adjusted to better align with the LCD for detection.

[0040] Furthermore, as Figures 2 - 3As shown, a partition 4 is fixedly installed in the heating box 1. A support mechanism 2 is arranged between the lower part of the partition 4 and the heating box 1. The space between the lower part of the partition 4 and the heating box 1 is a heating chamber for LCD aging. The heating chamber is clearly defined, enabling the LCD aging process to be carried out in a specific area, improving the stability and safety of the equipment. With the partition 4 for separation, the heating area can be better controlled, preventing heat from affecting other components, extending the service life of the equipment. At the same time, it is also convenient to adjust and monitor the temperature of the heating chamber, ensuring that the LCD aging process is carried out under suitable temperature conditions, and improving the accuracy and reliability of the aging test.

[0041] Further, as Figures 1 - 3 shown, the support mechanism 2 includes a rotating shaft 201 installed between the heating box 1 and the partition 4 through bearings. A polyhedron 203 is fixedly sleeved on the outer surface of the rotating shaft 201. The polyhedron 203 rotates with the rotating shaft 201. The polyhedron 203 has a clever structural design and can simultaneously perform aging tests on multiple LCDs, greatly improving the test efficiency. This is of great significance for large-scale production and quality inspection and can meet the requirements of high-efficiency production.

[0042] Further, the AOI camera 305 is aligned with one face of the polyhedron 203. When the LCD is undergoing the aging test, it is set on the side surface of the polyhedron 203. Therefore, aligning the AOI camera 305 with one face of the polyhedron 203 can make the AOI camera 305 align with the LCD during detection, facilitating monitoring and ensuring that the AOI camera 305 can accurately monitor the aging situation of the LCD, greatly improving the accuracy of detection. The AOI camera 305 aligned with the LCD can directly obtain the status information of the LCD, avoiding inaccurate detection caused by angle deviation. In this way, problems during the LCD aging process can be discovered in a timely manner, providing a strong guarantee for product quality control.

[0043] Further, as Figure 3 shown, a clamping part is installed on each face of the polyhedron 203. The clamping part is used for clamping the LCD, facilitating the fixation of multiple LCDs, effectively preventing the LCD from falling off during rotation, ensuring the smooth progress of the test. The clamping part can firmly fix the LCD, preventing it from shifting or falling during the rotation of the polyhedron 203, ensuring the stability and reliability of the test process. This is particularly important for long-term aging tests and can ensure the accuracy of the test results.

[0044] Further, as Figure 3As shown in the figure, the clamping part includes a support base 204 mounted on the polyhedron 203. A bidirectional lead screw 205 is mounted on the support base 204 through a bearing. Two clamping seats 206 are threadedly connected to the outer surface of the bidirectional lead screw 205. When the bidirectional lead screw 205 rotates, it can drive the two clamping seats 206 to approach or move away from each other, thereby realizing the clamping or release of the LCD, which can adapt to the clamping requirements of LCDs of different sizes, greatly improving the applicability of the device. The bidirectional lead screw 205 can adjust the distance between the clamping seats 206, so as to be able to clamp LCDs of different sizes, meeting the diverse production requirements, enabling the device to play a role in different production scenarios and improving the utilization rate of the device.

[0045] Embodiment Two of the Rotating LCD Aging Device with AOI of the Present Utility Model

[0046] For the rotating LCD aging device with AOI of the present utility model, the top end of the rotating shaft 201 passes through the partition plate 4 and is fixedly connected to a first driving motor 202. The first driving motor 202 is used to drive the rotation of the rotating shaft 201, providing a stable and reliable power source to ensure that the rotating shaft 201 can rotate smoothly, driving the polyhedron 203 and the LCD to rotate, enabling the AOI camera to comprehensively detect the aging condition of the LCD. The dedicated first driving motor 202 can accurately control the rotation speed and rotation direction of the rotating shaft 201 as needed, ensuring the accuracy and reliability of the test, which is crucial for achieving high-quality aging tests and can ensure that the LCD can be fully detected at different rotation speeds and rotation directions.

[0047] Embodiment Three of the Rotating LCD Aging Device with AOI of the Present Utility Model

[0048] For the rotating LCD aging device with AOI of the present utility model, a second driving motor is mounted on the top of the partition plate 4. The second driving motor is connected with a driving gear. The top end of the rotating shaft 201 passes through the partition plate 4 and is fixedly connected with a driven gear. The driven gear meshes with the driving gear. The second driving motor can drive the rotation of the rotating shaft 201 through the cooperation of the driving gear and the driven gear. Precise rotation speed control and large torque output can be achieved through gear transmission, ensuring that the rotating shaft 201 can still rotate stably under load. Gear transmission has the characteristics of accurate transmission ratio and high efficiency, which can meet the precision and power requirements of the rotating shaft 201 rotation of the LCD aging device, making the device more stable and reliable during operation and improving the service life and test precision of the device.

[0049] In use, the LCD is clamped at the clamp seat 206 and rotates under the drive of the rotating shaft 201 and the polyhedron 203. The third drive motor 303 can drive the lifting of the slide seat 302 through the drive gear 304 and the rack 301, and then can drive the lifting of the AOI camera 305 to adjust the height of the AOI camera 305 according to actual needs. During the rotation process, the state of the LCD is monitored through the AOI camera 305.
