Description

Technical Field

[0001] The utility model relates to the technical field of liquid crystal glass processing, in particular to a liquid crystal glass top crack removal mechanism. Background Art

[0002] The key steps in the LCD panel production process involve the electrode preparation of TFT (Thin Film Transistor) glass and the assembly and covering of CF (Color Film), however, this leads to a challenge: the electrodes on the TFT glass are blocked by CF, which hinders direct IC (Integrated Circuit) bonding. Therefore, it is necessary to remove part of the CF on the TFT glass, the so-called residual material, to ensure the smooth subsequent IC bonding. However, the residual material on the CF surface may be tightly adhered to the substrate due to electrostatic adsorption or other physical forces, making cleaning more difficult. Appropriate cleaning methods need to be adopted to ensure that the residual material can be effectively removed.

[0003] The existing process of removing residual materials mainly includes cutting and stripping. Cutting usually uses diamond tools or laser cutting machines to cut the residual materials and CF, and then the residual materials are stripped by blowing, pressure rods and other mechanisms. This method has a low success rate when stripping CF residual materials, and some residual materials cannot be completely removed. As the glass becomes thinner and the size increases, this problem becomes more serious; in the face of the residual material stripping of thinned products, it mainly relies on manual labor, which not only reduces production efficiency, but also increases processing time and cost.

[0024] The flip unit 2 is installed on the upper end surface of the workbench 1 and is used to fix the liquid crystal glass. It is composed of two supporting vertical plates 21, a rotating shaft 22, a rotating motor 23, a vacuum platform A24, a vacuum platform B25, a coupling 27, an air slip ring 28 and a bearing 29; the two supporting vertical plates 21 are relatively arranged on the upper end surface of the workbench 1, the rotating shaft 22 is located between the two supporting vertical plates 21, the output shaft of the rotating motor 23 is connected to one end of the rotating shaft 22 through the coupling 27, and the rotating motor 23 drives the rotating shaft 22 to realize a 180-degree rotation action, the air slip ring 28 is connected to the end of the rotating shaft 22 opposite to the rotating motor 23, the vacuum platform A24 and the vacuum platform B25 are connected to the rotating shaft 22, and the vacuum platform A24 and the vacuum platform B25 are connected to the rotating shaft 22. Platforms B25 are respectively installed on both sides of the rotating shaft 22 and are arranged in parallel. The vacuum platform evenly distributes the vacuum area according to the specifications of the liquid crystal panel to achieve type switching. Multiple vacuum holes 26 are evenly distributed on the vacuum platform A24 and the vacuum platform B25. The two vacuum platforms can absorb a liquid crystal panel at the same time. When the vacuum platform A24 is flipped to the residual material removal position, the vacuum platform B25 can cache one piece, which increases the time for residual material removal and improves production efficiency. The rotating motor 23 is fixedly connected to a supporting vertical plate 21 on the same side, and one end of the rotating shaft 22 where the air slip ring 28 is located is fixedly connected to the other supporting vertical plate 21 through a bearing 29.

[0025] The scrap removal unit 3 is arranged between the workbench 1 and the flip unit 2, and includes an X-axis module 31 and a Z-axis module 32 which are arranged vertically. The Z-axis module 32 is located at the lower end surface of the X-axis module 31 and penetrates the workbench 1 downward, wherein the X-axis module 31 is composed of a bottom plate 311, a guide rail 312, a slider 313, a mounting plate 314, a mounting seat 315, a wind knife 316, a top block 317, and the bottom plate 311 is fixedly mounted on the workbench 1, and the guide rail 312 is fixedly mounted on the top end of the bottom plate 311 and extends along the bottom plate 31 1 is arranged in the width direction, the slider 313 is slidably mounted on the guide rail 312, the lower end surface of the mounting plate 314 is fixedly connected to the upper end surface of the slider 313, the mounting seat 315 is fixedly mounted on the end of the bottom plate 311 opposite to the guide rail 312, a cross plate is arranged between the mounting seat 315 and the mounting plate 314, the top block 317 is mounted on the cross plate, the wind knife 316 is arranged above the top block 317, the wind knife angle adjustment blocks 318 are respectively arranged at both ends of the wind knife 316, and the bottom end of the wind knife angle adjustment block 318 on one side is fixed to the mounting seat 315 The bottom end of the wind knife angle adjustment block 318 on the other side is fixedly connected to the mounting plate 314. The blowing angle is adjusted by the wind knife angle adjustment block 318 to effectively clean the residual material dropped on the top block. The top block 317 is made of anti-static wear-resistant engineering plastic or anti-static metal material. After the liquid crystal glass is processed by the cutting machine, a groove will be formed on the surface to generate micro cracks. When external force is applied to the brittle material, the stress at the tip of the micro crack will increase exponentially, and as the external force increases, the length of the micro crack also increases, that is, the micro crack expands, and the top Block 317 acts on the cracks in the residual material, causing the microcracks to increase and causing micro-elastic deformation of the liquid crystal glass. Under this dual action, the contact area between the residual material and the liquid crystal glass becomes smaller, the strain increases, and fracture separation is achieved; the Z-axis module 32 is composed of a connecting plate 321, a flange 322 arranged on one side of the connecting plate 321, and a Z-axis motor 323 connected to the lower end of the connecting plate 321, wherein the outer side of the flange 322 is connected to a lifting connecting plate 324, and the top end of the lifting connecting plate 324 is connected to the lower end surface of the bottom plate 311.

[0026] The residual material detection unit 4 is fixedly mounted on the mounting seat 315, and performs visual inspection on the top block 317 to determine whether there are foreign objects on the top block 317. When foreign objects remain on the top block 317, the system issues an alarm message to prompt manual intervention, effectively reducing the generation of scrap and recording production data to ensure product traceability. The residual material detection unit 4 is composed of a fixed seat 41, a prism 42, a fine-tuning platform 43, a lens 44, a point light source 45, a camera 46 and a ring light 46; the bottom end of the fixed seat 41 is fixedly connected to the top end of the mounting seat 315, the prism 42 is mounted on the fixed seat 41 close to the side of the mounting seat 315, the fine-tuning platform 43 is fixedly connected to the bottom of the fixed seat 41, and the prism 42 is fixedly connected to the bottom of the fixed seat 41.

Under the illumination of the light source, the camera 46 captures the target residual material image through the lens 44, and transmits the data to the PC system, which processes the image and determines that if the residual material is not removed, the system will control the residual removal unit 3 to process it again. Only the liquid crystal glass with the residual material not removed will be processed for the second time, which effectively improves the overall work efficiency and ensures that each piece of residual material is processed to ensure product quality.

[0027] like Figure 5 As shown, in actual operation, the liquid crystal glass to be removed is first fixed on the vacuum platform A24. When the vacuum platform A24 is flipped to the removal position, the position of the top block 317 is accurately controlled by the X-axis module 31 and the Z-axis module 32, and pressure is applied to separate the CF residual material 6 from the liquid crystal glass. The wind knife 316 removes the CF residual material 6 on the top block 317. The residual material detection unit 3 then detects the removal effect to ensure that the surface of the liquid crystal glass is clean. If the CF residual material 6 is not completely removed, the residue removal unit 3 will perform the removal operation again.
