Description

Technical Field

[0001] This utility model relates to the technical field of liquid crystal display panel production equipment, and in particular to a liquid crystal display panel loading platform. Background Technology

[0002] In the production process of LCD panels, the loading platform is used to carry and position the cassettes containing the LCD panels for subsequent bonding work. As LCD panels develop towards larger sizes and higher precision, traditional loading platforms face the following technical challenges when carrying ultra-large cassettes:

[0003] Difficulty in limiting position: The large size of the material box is heavy and long, and the traditional fixed limiting structure is difficult to achieve stable positioning. It is easy to cause displacement or vibration due to uneven force, which affects the feeding accuracy.

[0004] Poor compatibility: It cannot be flexibly adjusted to adapt to LCD panel material boxes of different specifications (such as different lengths and widths), which requires manual adjustment or replacement of fixtures when changing models, affecting production efficiency;

[0005] Low level of automation: Some feeding platforms rely on manual adjustment of limit mechanisms, which is not only cumbersome to operate, but also prone to human error, making it difficult to meet the needs of high-precision automated production. Utility Model Content

[0028] Please refer to the following: Figure 1This utility model provides a material loading platform for a liquid crystal display panel, including a material box 1 for carrying the liquid crystal display panel, an upper frame 2 for supporting the material box 1, and a lower frame 3 connected below the upper frame 2. The upper frame 2 is provided with a limiting component and a positioning component 21 for fixing the material box 1. The limiting component includes a first limiting part 22, a second limiting part 23, and a third limiting part 24. The positioning component 21 includes positioning parts 210 for pressing against both sides of the material box 1.

[0029] Please refer to the following: Figure 2 The first limiting part 22 includes a first limiting plate, a first driving mechanism for driving the first limiting plate to move vertically, and a second driving mechanism for driving the first limiting plate to move horizontally. The second driving mechanism includes a synchronous pulley 225, an idler pulley, and a synchronous belt 227 surrounding the synchronous pulley 225 and the idler pulley. The synchronous belt 227 engages with a toothed connector, which is fixedly connected to a slider connector, so that the synchronous belt 227 is always kept taut. The slider connector is fixedly connected to a Z-axis mounting plate 224. The Z-axis mounting plate 224 is provided with vertical guide rails 221 and longitudinal guide rails 222 arranged perpendicularly to each other. The synchronous pulley 225 is provided with a drive shaft 228 with a shaft hole. The drive shaft 228 passes through a locking block 229 and is connected to an operating handle 226. The locking block 229 is provided with fasteners 220 for locking the position of the synchronous belt 227. The first driving mechanism includes a cylinder 223 connected to the vertical guide rail 221, and the output end of the cylinder 223 is connected to the first limiting plate.

[0030] Please refer to the following: Figure 3 The second limiting part 23 includes a third driving mechanism 230, a fourth driving mechanism 231, and a second limiting plate 25. The third limiting part 24 includes a fifth driving mechanism 240, a sixth driving mechanism 241, and a third limiting plate 26. The third driving mechanism 230 and the fifth driving mechanism 240 drive the second limiting plate 25 and the third limiting plate 26 to move vertically. The fourth driving mechanism 231 and the sixth driving mechanism 241 drive the second limiting plate 25 and the third limiting plate 26 to limit the material box 1 longitudinally. The first driving mechanism, the second driving mechanism, the third driving mechanism 230, and the fourth driving mechanism 231 are integrated and installed on the upper frame 2. The lower frame 3 is provided with a moving mechanism 31, which drives the upper frame 2 to move longitudinally. The positioning component 21 includes positioning parts 210 for pressing against both sides of the material box 1.

[0031] When material box 1 is being loaded, if the four sides of material box 1 are A1 and A2 (horizontal length) and B1 and B2 (vertical width), the moving mechanism 31 is activated. The motor drives the synchronous belt combination to rotate, causing the upper frame 2 to move along the guide rail of the lower frame 3 to the loading position. At this time, the first drive mechanism, the third drive mechanism 230, and the fifth drive mechanism 240 are activated, and the corresponding cylinder 223 retracts, which will drive the first limit plate, the second limit plate 25, and the third limit plate 26 to move vertically downward. This causes the first limit plate, the second limit plate 25, and the third limit plate 26 to descend along the vertical guide rail 221 until their height is lower than that of material box 1. This prevents collisions between material box 1 and the first limit plate, the second limit plate 25, and the third limit plate 26 during loading, achieving dynamic avoidance of collisions in the loading path. Subsequently, the material box 1 carrying the LCD panel is placed on the upper frame 2 by an external conveying arm. The first drive mechanism, the third drive mechanism 230, and the fifth drive mechanism 240 are activated again, and the cylinder 223 extends, which drives the first limit plate, the second limit plate 25, and the third limit plate 26 to move vertically upward, so that the first limit plate, the second limit plate 25, and the third limit plate 26 are higher than the height of the upper frame 2. The upper frame 2 is reset by the moving mechanism 31. At this time, the A1 and B1 sides are aligned with the upper frame 2. The positioning components 210 are in close contact, completing the initial positioning of sides A1 and B1 and preventing displacement. If the material box 1 has different specifications and the positioning position of the first limiting part 22 on side B2 needs to be adjusted, the fastener 220 on the locking block 229 is loosened, the operating handle 226 is rotated, and the transmission shaft 228 drives the synchronous wheel 225 and the idler wheel to rotate, thereby causing the first limiting plate to move laterally along the longitudinal guide rail 222 until it is close to side B2 of the material box 1. Then, the fastener 220 is tightened to lock the position of the synchronous belt 227, completing the precise positioning of side B2. Finally, the fourth drive mechanism 231 and the sixth drive mechanism 241 are activated, driving the second limiting plate 25 and the third limiting plate 26 to move along the corresponding guide rails, so that they are close to side A2 of the material box 1, completing the comprehensive positioning and positioning of all four sides of the material box 1, eliminating the deflection of the material box 1 caused by unilateral pushing.

[0032] Through the above specific embodiments, the liquid crystal display panel feeding platform of this utility model can efficiently and accurately complete the feeding and positioning of material boxes 1 of different specifications, and meet the actual needs in the liquid crystal display panel production process.
