Description

Technical Field

[0001] The invention relates to the technical field of liquid crystal panel production and processing, in particular to a heat pressing buffer material strength detection device for liquid crystal panels. Background Art

[0002] Liquid crystal panel is a key component widely used in display devices. It is mainly composed of liquid crystal material, glass substrate, polarizer, color filter and other materials. From the structural point of view, the liquid crystal material is sandwiched between two glass substrates, like a "sandwich" structure. Liquid crystal material is the core element of liquid crystal panel to display images. It has special physical properties. Under the action of electric field, the arrangement of liquid crystal molecules will change.

[0003] Polarizers are located on both sides of the glass substrate. Their function is to control the propagation direction of light. Color filters are responsible for presenting rich and colorful colors. By combining with the modulation of light by liquid crystal molecules, different pixels can display different colors. When an external signal is applied to the liquid crystal panel, the electric field will change the arrangement of liquid crystal molecules, thereby changing the transmission and blocking of light. After the synergistic effect of a series of optical elements such as color filters and polarizers, the electrical signal is finally converted into an image that our eyes can see. Liquid crystal panels are indispensable in many electronic devices such as TVs, computer monitors, and mobile phone screens. Its performance parameters such as resolution, contrast, and response time directly affect the visual effect of display devices.

[0004] At present, the detection of liquid crystal panels usually needs to go through a knocking process and an inspection process. During the existing knocking detection, a special knocking detection device is usually required to assist in the detection. However, the existing detection device still has certain defects and shortcomings. For example, a Chinese patent with a publication number of "CN205844671U" discloses a liquid crystal panel detection device, which includes: a light-emitting base for carrying a liquid crystal panel; a first guide rail arranged along a vertical direction; a pressure head slidably assembled on the first guide rail, and the pressure head includes a pressure nozzle arranged toward the light-emitting base. Compared with the prior art, the embodiment of the utility model only needs to use one device to complete the detection of the liquid crystal panel, which greatly improves the detection efficiency; in addition, the technical solution saves the time of transferring the liquid crystal panel from the knocking device to the inspection device. When the pressure nozzle knocks the liquid crystal panel, it can immediately detect whether there are bubbles inside the liquid crystal panel under the illumination of the light-emitting base, thereby greatly improving the accuracy of liquid crystal panel detection and helping to improve the product quality of the liquid crystal panel;

[0005] During the overall use of the above-mentioned device, although it can be assisted by the pressure head for detection, there are certain defects and shortcomings in the specific detection process. First, during the detection process, the compressive resistance of the top of the liquid crystal panel buffer material near the edge and near the middle is often different. However, the above-mentioned device can only perform impact detection on a single position on the top of the liquid crystal panel, which obviously greatly reduces its detection adaptability and cannot fully and accurately reflect the compressive performance of the liquid crystal panel buffer material at different positions. Secondly, during the detection process, the device can only detect liquid crystal panel buffer materials of a single specification. Once the size and thickness of the liquid crystal panel buffer material change, it becomes extremely inflexible and cannot be conveniently positioned. It can be seen that the overall adaptability of the device during use is poor, and it is difficult to meet the detection needs of liquid crystal panel buffer materials of different specifications. Therefore, it is urgent to improve it. Summary of the invention

[0040] The working principle of the present invention is as follows: by setting up the detection device 2, the clamping device 6 can be used to assist in clamping and fixing the hot pressing buffer material of the liquid crystal panel during the detection process. At this time, the electric push rod 21 is started to run, and the electric push rod 21 can drive the impact block 23 to move downward. After the impact block 23 moves downward, it can impact the hot pressing buffer material at the bottom. During the detection process, it can be flexibly adjusted according to specific needs. By starting the third motor 222, the base shaft 223 inside the concave seat 221 is driven to rotate, thereby changing the angle of the impact block 23 at the bottom of the installation frame 225. By adjusting the angle of the impact block 23 The contact area of ​​the bottom of the impact block 23 during impact can be adjusted.

When testing, the pressure sensor 224 can be used to assist in detecting the pressure during the impact, so as to facilitate accurate recording of the compressive strength value of the liquid crystal panel hot pressing buffer material, which greatly improves the convenience of the overall use of the device.

[0041] By setting the clamping device 6, the device can fill the liquid crystal panel hot pressing buffer material between the inner sides of the two frames 61 during use. If the specifications are not suitable, the first motor 32 can be started to run. After the first motor 32 runs, it drives the first screw rod 31 to rotate inside the guide rail 5. Since the two ends of the first screw rod 31 have opposite screw directions, the two sliders 33 can be synchronously driven to rotate at the two ends inside the guide rail 5. The sliders 33 slide back and forth inside the guide rail 5, and then the sliders 33 can be flexibly adjusted to drive the frame 61 to move back and forth. By adjusting the spacing of the frame 61, liquid crystal panel buffer materials of different sizes can be flexibly adapted. During use, the frame 61 can be moved by the movement of the frame 61. The transmission mechanism 9 can also be triggered to drive the positioning component 62 and the covering component 63 to flexibly adapt to the clamping. After the clamping is completed, the impact detection is performed through the detection device 2. During the impact detection process, the transmission belt 65 inside the frame 64 can be driven to rotate by starting the second motor 66. When the frame 61 clamps the liquid crystal buffer material, the inner side of the transmission belt 65 can stably fit the outer surface of the buffer material. By starting the second motor 66 to drive the transmission belt 65 to rotate, the liquid crystal panel buffer material can be driven to reciprocate forward and backward. At this time, the impact detection can be flexibly performed on the top edge or any position in the middle of the liquid crystal panel buffer material, which can further improve the detection performance of the device during the overall use.

[0042] During use, when the screw rod rotates, it can synchronously drive the frame 61 to move back and forth. The displacement of the frame 61 can drive the gear 92 at its bottom to move, and the gear 92 is meshed with the rack 93 on the connecting arm 91. As the gear 92 linearly moves while the rack 93 does not move, the gear 92 can be reversely driven to drive the second screw rod 622 inside the vertical rail 621 to rotate. The rotation of the second screw rod 622 can drive the movable block 623 to slide inside the vertical rail 621. During the displacement of the frame 61 toward the inside, the screw rod can be synchronously driven to drive the movable block 623 to move downward. The downward movement of the movable block 623 can assist in covering and extruding the liquid crystal panel substrate inside the frame 61. During use, due to the provision of a telescopic spring 633, the telescopic spring 633 is provided to push the concave frame 634 to move, so that a position can be reserved for the concave frame 634, and the telescopic spring 633 is used to push the concave frame 634 to perform position compensation. When clamping hot-pressed buffer materials of different thicknesses, the telescopic spring 633 pushes the concave frame 634 to drive the top guide roller 635 to fit tightly against the outer surface of the buffer material, so that the top of the buffer material can be clamped and positioned, which can improve the stability of the buffer material during detection. In addition, the elastic reserved design of the telescopic spring 633 can flexibly adapt to clamping buffer materials of different thicknesses, further improving the adaptability of the device during overall use.
