Description

Technical Field

[0001] This utility model relates to the technical field of polarizer production equipment, and in particular to a large-size polarizer edge grinding machine. Background Technology

[0002] Large-size polarizers typically refer to polarizers used in LCD panels of 9 inches and above. A polarizer is an optical film material composed of a composite of TAC film, PVA film, protective film, bulking film, pressure-sensitive adhesive, and phase retardation film. Its basic structure consists of two layers of TAC film sandwiching a stretched PVA film. Large-size LCD panels, such as television screens, require matching large-size polarizers during production. However, after cutting during production, the edges of the polarizer are often not smooth and neat, and the dimensional accuracy is difficult to meet requirements. Large-size polarizer edge grinding machines can perform high-precision edge grinding on large-size polarizers, achieving high dimensional accuracy, smooth and neat edges, and no adhesive residue, thus meeting the needs of large-size panel production.

[0003] In operation, the large polarizing film with rough edges after cutting is first placed in the loading area and fixed. After startup, the conveyor system sends the polarizing film to the edge grinding work area. Under the precise control of the control system, the high-precision grinding wheel rotates at high speed according to preset parameters to grind the edges. The cylindrical conveyor system then sends the finished product to the unloading area, where the operator takes it out for subsequent inspection or large-size LCD panel assembly.

[0004] In existing technologies, some polarizer edge grinding machines can only grind one side of the polarizer first, and then flip it over to process the other side. This alternating process increases the turnover time of the polarizer in the equipment and the number of operation steps. For example, when processing 86-inch large-size polarizers, this step-by-step grinding method greatly reduces the overall edge grinding efficiency, prolongs the production cycle, and leads to a decrease in production efficiency. Therefore, to address these shortcomings, a large-size polarizer edge grinding machine is proposed to solve the above problems. Utility Model Content

A side frame 24 is fixedly connected to the left side of the positioning frame 20, providing installation space for subsequent components. An electric push rod 25 is fixedly connected to the rear inner wall of the side frame 24, pushing the subsequent components horizontally. A push plate 26 is fixedly connected to the drive end of the electric push rod 25, sliding under the thrust of the electric push rod 25. A push plate 27 is fixedly connected to the top side of the sliding block 23. The push plate 27 can correct and position the polarizer in the horizontal direction under the drive of the sliding block 23.

[0040] Reference Figure 1 , Figure 7 and Figure 8 The feeding mechanism includes a feeding box 32, which stores a large number of polarizing films to be processed. Its bottom side is fixedly connected to the front top side of the base plate 1, and its stability is increased through welding. A discharge box 31 is fixedly connected to the right top side of the base plate 1, which collects polarizing films that have undergone edge grinding. A connecting frame 33 is fixedly connected to the rear side of the feeding box 32. Multiple transmission belts 34 are installed inside the connecting frame 33, providing a mounting base for the transmission belts 34 and other components. The transmission belts 34, driven by power, sequentially transport the polarizing films in the feeding box 32 to the processing area. A concave frame 35 is fixedly connected to the outer side of the connecting frame 33, providing support for the installation of subsequent components. A drive assembly for driving the rotation of subsequent components is fixedly connected to the inner wall of the top of the concave frame 35. The drive assembly includes a motor 36, which serves as the power source for the drive assembly, and its top is fixedly connected inside the concave frame 35. A rotating shaft 37 is fixedly connected to the drive end of motor 6 36, and the rotating shaft 37 can rotate under the drive of motor 6 36. A gear 38 is fixedly connected to the bottom end of the drive assembly, and the bottom end of the rotating shaft 37 is fixedly connected inside the gear 38, and the gear 38 rotates under the drive of the rotating shaft 37.

[0041] Racks 39 are slidably connected to both the front and rear sides of the inner wall of the concave frame 35. The outer side of the gear 38 is meshed with the outer side of the two racks 39. When the gear 38 rotates, the racks 39 slide horizontally within the concave frame 35 due to the meshing action. Support blocks 40 are fixedly connected to the opposite sides of the two racks 39. The racks 39 push the support blocks 40 to slide when subjected to force. Connecting blocks 41 are fixedly connected to the opposite sides of the two support blocks 40, transmitting the sliding force of the support blocks 40 to subsequent components. T-shaped openings 42 are provided at both the front and rear ends of the concave frame 35, providing space for the sliding of subsequent components. Limiting blocks 43 are fixedly connected to the opposite sides of the two racks 39, pushing the limiting blocks 43 to slide when subjected to force. Limiting plates 44 are fixedly connected to the bottom side of the limiting blocks 43, transmitting the sliding force of the limiting blocks 43 to subsequent components through the limiting plates 44. Two limiting plates 44 are slidably connected to the inner walls of the left and right ends of the concave frame 35, respectively. The limiting plates 44 can further restrict and guide the sliding of the rack 39. A clamping plate 45 is fixedly connected to the bottom side of the limiting plate 44. The clamping plate 45 can move up and down under the action of the rack 39, thereby limiting the movement of large-sized polarizers of different sizes and preventing displacement.

[0042] Working principle: The polarizer in the loading box 32 is placed on the transmission belt 34. Then, the drive motor 36 drives the rotating shaft 37 to rotate, which in turn drives the gear 38 to rotate. The gear 38 meshes with the rack 39, so that the rotation of the gear 38 can drive the two racks 39 to slide in opposite directions. Then, the racks 39 drive the limiting block 43 to slide, which in turn drives the limiting plate 44 to slide, and then drives the clamping plate 45 to slide. The distance between the two clamping plates 45 can be adjusted according to the size of the polarizer, thereby achieving the guidance and correction of the polarizer.

[0043] The polarizer is then fed to the adjustment mechanism. Motor 4 drives the disc 5 to rotate, causing the fixed frame 6 and the limiting frame 7 to rotate with the disc 5, thus adjusting the angle of the polarizer. Cylinder 9 drives the pressure plate 30 to move up and down, pressing or releasing the polarizer. Motor 10 drives the lead screw 11 to rotate, causing the sliding block 12 to move horizontally, thereby achieving fine-tuning of the horizontal alignment of the connecting frame 3 and the upper components, allowing the polarizer to slide to the grinding position. In the positioning frame 20, motor 21 drives the lead screw 22 to rotate, causing the sliding block 23 to move the push plate 27 horizontally. Simultaneously, the electric push rod 25 pushes the push plate 26 horizontally. Both work together to precisely position and correct the polarizer horizontally, ensuring accurate polarizer positioning. During grinding, motor 28 drives the grinding wheel 29 to rotate at high speed, and motor 3 14 drives the bidirectional lead screw 15 to rotate, causing the connecting block 16 to drive the sliding box 17 to move horizontally along the guide rail 18 on the support frame 13. The guide block 19 ensures smooth sliding. The grinding wheel 29 driven by motor 28 grinds the edge of the polarizer. The bidirectional lead screw 15 can realize the movement of the two sliding boxes 17 in relative or opposite directions, so that the polarizer can be ground on both sides at the same time, thereby improving work efficiency.
