Description

Technical Field

[0001] This utility model relates to the field of equipment technology, specifically to a liquid crystal panel stacking device. Background Technology

[0002] Thin-film transistor liquid crystal displays (TFT-LCDs) are widely used in industrial control, especially in industrial control displays. Industrial control displays are highly reliable, durable, and adaptable, capable of stable operation in harsh environments. They typically use industrial-grade components, supporting long-term continuous operation with a lifespan of tens of thousands of hours. Industrial control displays have a wide operating temperature range, with some high-end models even supporting operating temperatures from -30℃ to 80℃, making them suitable for extreme environments.

[0003] TFT-LCD production is mostly automated. During the production process, the core component is the LCD panel. The LCD panel is large in size and light in weight, and it is easily broken by impact. Generally, a robotic arm is used in conjunction with a suction cup for transfer. The suction cup grabs the panel and then transfers it to a fixed point. The robotic arm can usually only grab one panel at a time. However, packaging is usually done in batches. If the robotic arm is used to transfer the panels directly, there will be a large error in the placement of the products. During the movement, even slight bumps to the edges and corners can easily damage the products. Utility Model Content

[0004] To overcome the above-mentioned defects, the purpose of this utility model is to provide a liquid crystal panel stacking device, which can organize and transfer liquid crystal panels, reduce the accumulation of original errors, and meet the needs of rapid product packaging.

[0005] To achieve the above objectives, this utility model provides a liquid crystal panel stacking device, including a frame, on which a material transfer mechanism, a straightening mechanism, and a feeding mechanism are provided; the material transfer mechanism includes a crossbeam and a crossbeam slide, the crossbeam slide being slidably connected to the crossbeam, and a material transfer gripper being installed at the bottom of the crossbeam slide; a support plate is fixedly provided on the frame, the support plate having a material drop hole, and the straightening mechanism being located within the material drop hole; the straightening mechanism includes a material support plate, an X-axis slide, an X-axis guide rail, and a straightening power cylinder, the material support plate being fixedly connected to the end of the X-axis slide, the X-axis slide being slidably connected to the X-axis guide rail, the straightening mechanism being located between the two X-axis guide rails, and the piston rod of the straightening power cylinder being fixedly connected to the material support plate; the feeding mechanism includes a Z-axis lifting seat, the Z-axis lifting seat being slidably connected to the Z-axis guide rail, and the Z-axis lifting seat having a Z-axis material support plate fixedly provided.

[0006] Preferably, there are two sets of the straightening mechanism, symmetrically arranged on both sides of the discharge hole in the X direction.

[0007] Preferably, the material support plate is stepped.

[0008] Preferably, the bottom of the feeding mechanism is also provided with a Y-direction conveyor belt, and there are two sets of Y-direction conveyor belts, which are respectively arranged on both sides of the Z-direction material support plate.

[0009] Preferably, a guide plate is provided between the material discharge hole and the Y-direction conveyor belt, and the upper end of the guide plate is folded outward.

[0010] Preferably, the material support plate is also equipped with several material level detection sensors.

[0011] The beneficial technical effects achieved by this utility model after adopting the above technical solution are as follows:

[0012] 1. Because the frame is equipped with a material transfer mechanism, a straightening mechanism, and a feeding mechanism; the material transfer mechanism grabs the thin-film transistor liquid crystal display, the straightening mechanism straightens it at any time, and then the feeding mechanism realizes the conveying. The above equipment can adjust the position of the product at any time, which can avoid the accumulation of original errors. Therefore, the product will not have a large positional deviation during the conveying process, which makes it easier to convey in batches and is more friendly to the downstream packaging process.

[0013] 2. Due to the adoption of a straightening mechanism consisting of a material support plate, an X-axis slide block, an X-axis guide rail, and a straightening power cylinder, the material support plate is fixedly connected to the end of the X-axis slide block, the X-axis slide block is slidably connected to the X-axis guide rail, the straightening is located between the two X-axis guide rails, the piston rod of the straightening power cylinder is fixedly connected to the material support plate, and a material level detection sensor is generally used on the material support plate. According to the detection height, the straightening power cylinder can be activated at any time, allowing the material support plate to move along the X-axis guide rail. The straightening mechanism of this utility model can not only be applied to LCD panels, but also to downstream products of LCD panels, such as the straightening of thin-film transistor liquid crystal displays or display housings. During the entire straightening process, the operator will not be touched, thus avoiding fingerprints and sweat, further ensuring the product qualification rate. Attached Figure Description

[0023] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely for explaining the present utility model and are not intended to limit the present utility model.

[0024] See Figures 1-4 This invention provides a liquid crystal panel stacking device, including a frame 1. The frame 1 is equipped with a material transfer mechanism 2, a straightening mechanism 3, and a feeding mechanism 4. The frame 1 supports the entire equipment. The material transfer mechanism 2 transfers the finished products to the dropping holes 12 of the frame 1. The straightening mechanism 3 adjusts the angle, and the feeding mechanism 4 then conveys the products. This invention is applicable to thin-film products, such as liquid crystal panels and carrier glass, and can also be applied to the straightening of finished ultra-thin displays, such as OLED liquid crystal displays.

[0025] The material transfer mechanism 2 includes a crossbeam 21 and a crossbeam slide 22. The crossbeam slide 22 is slidably connected to the crossbeam 21, and a material transfer gripper 23 is also installed at the bottom of the crossbeam slide 22. The crossbeam 21 supports the crossbeam slide 22. Driven by the motor, the crossbeam slide 22 slides along the crossbeam 21, driving the material transfer gripper 23 to move. Generally, the material transfer gripper 23 is also equipped with a lifting cylinder. After lowering to a certain height, the material transfer gripper 23 uses vacuum adsorption to quickly grasp and transfer thin-film LCD panels. Material transfer gripping is a mature existing technology.

[0026] A support plate 11 is fixedly mounted on the frame 1. The support plate 11 has a material discharge hole 12, and the straightening mechanism 3 is located inside the material discharge hole 12. The straightening mechanism 3 includes a material support plate 31, an X-axis slide block 32, an X-axis guide rail 33, and a straightening power cylinder 34. The material support plate 31 is fixedly connected to the end of the X-axis slide block 32, the X-axis slide block 32 is slidably connected to the X-axis guide rail 33, the straightening mechanism is located between the two X-axis guide rails 33, and the piston rod of the straightening power cylinder 34 is fixedly connected to the material support plate 31. See also Figure 3Taking an LCD panel as an example, the LCD panels are placed on the support plate 31. Generally, when ten panels are placed, the straightening mechanism 3 starts to operate. The straightening power cylinder 34 is generally a pneumatic cylinder or an electric cylinder. The piston rod of the straightening power cylinder 34 drives the support plates 31 on both sides to move inward. When the support plates 31 move inward, they push the multiple LCD panels with protruding edges to a flush position. The support plate 31 is stepped, which can better place the LCD panels.

[0027] The feeding mechanism 4 includes a Z-axis lifting seat 41, which is slidably connected to a Z-axis guide rail 42. A Z-axis support plate 43 is fixedly mounted on the Z-axis lifting seat 41. After the LCD panel is aligned, it is positioned at the center of the discharge hole 12. The Z-axis support plate 43 is lifted upwards, and just before it contacts the LCD panel, the alignment power cylinder 34 drives the support plate 31 to retract, preventing the LCD panel from being subjected to force on both sides. The Z-axis guide rail 42 is used for guidance. In general use, the Z-axis support plate 43 can be adjusted to a certain height first to support the LCD panel, and then the angle of the LCD panel can be adjusted by the alignment mechanism 3, which is safer. The Z-axis support plate 43 is located between the two Y-axis conveyor belts 13. After descending a certain height, the Y-axis conveyor belts 13 can just support the LCD panel and transport it downstream.

[0028] The straightening mechanism 3 of this utility model consists of two sets, symmetrically arranged on both sides of the discharge hole 12 in the X direction. This utility model demonstrates two sets of straightening mechanisms 3; however, only one set can be used, with a positioning plate (not shown in the figure) pre-installed at the other end. Using one set of straightening mechanisms 3 is generally suitable for larger finished products, such as ultra-thin displays, where they have stronger pressure resistance. Simultaneous operation of both sets of straightening mechanisms 3 results in higher efficiency and a wider range of applications.

[0029] The material support plate 31 of this utility model is stepped. The stepped material support plate 31 is used to place and hold the LCD panels. During initial debugging, to prevent damage to the product from excessive force, the inner wall of the material support plate 31 is covered with auxiliary equipment such as silicone pads, or limit blocks and sensors are added to prevent the movement distance from exceeding the set value. Generally, multiple LCD panels are placed first, and then the material is straightened. This prevents a single LCD panel from being too thin and directly deformed by pressure.

[0030] The bottom of the feeding mechanism 4 of this utility model is also provided with a Y-direction conveyor belt 13. There are two sets of Y-direction conveyor belts 13, which are respectively set on both sides of the Z-direction support plate 43. When there is a certain distance between the conveying positions, the Y-direction conveyor belts 13 can be installed. The Y-direction conveyor belts 13 realize the conveying of materials through friction. Therefore, after stacking multiple thin LCD panels together, the friction increases and there will be no obvious displacement deviation during the conveying process.

[0031] In this invention, a guide plate 44 is provided between the material drop hole 12 and the Y-axis conveyor belt 13, with the upper end of the guide plate 44 folded outward. The guide plate 44 is used for initial guidance and limiting during descent, ensuring better positioning with the Y-axis conveyor belt 13 below, and further improving the accuracy of the material transfer position.

[0032] The material support plate 31 of this utility model is also fixedly equipped with several material level detection sensors 35. The material level detection sensors 35 are mature existing technology and can be purchased directly. They generally detect the height of the material through sound waves or infrared rays.

[0033] Of course, there may be other embodiments of this utility model. Without departing from the spirit and essence of this utility model, those skilled in the art can make various corresponding changes and modifications based on this utility model, but these corresponding changes and modifications should all fall within the protection scope of the appended claims of this utility model.
