Description

Technical Field

[0001] This utility model relates to the field of polarizer punching and collecting technology, specifically a polarizer punching and collecting device. Background Technology

[0002] Polarizing film is one of the three key components of liquid crystal displays (LCDs). It is a composite material made by stretching polyvinyl alcohol (PVA) film and bonding it with triacetate cellulose (TAC) film, enabling LCDs to achieve high brightness and high contrast characteristics. Polarizing films used in displays are made by cutting a polarizing film master (polarizing strip) using a die-cutting machine. The master is usually produced in roll form, which is fed onto a conveyor line to form a strip that is then die-cut by the die-cutting machine to form the polarizing film.

[0003] Chinese Patent Publication No. CN222755651U discloses a polarizer punching and receiving device, which includes a worktable and a receiving device. The worktable has a receiving groove and two symmetrically distributed supports. The receiving device, located on the worktable, includes a pressing mechanism mounted on the supports, two vertically arranged plates within the receiving groove, a receiving box within the receiving groove, and a receiving mechanism mounted on the vertical plates. The pressing mechanism includes a pressure plate with a groove at its bottom, three rollers horizontally arranged within the groove, a driving assembly for vertically moving the pressure plate, and a connecting assembly for connecting the driving assembly and the pressure plate. The receiving box is located to the side and below the receiving mechanism. This invention can reduce wear on the edges of the polarizer and prevent missed collection when the polarizer material is soft.

[0004] The aforementioned device conveys the polarizing film master tape to the area below the cutting mechanism, where it is then punched by a die. However, the polarizing film master tape lies flat above the conveying device during transport, preventing it from being kept taut. Excessive die-cutting pressure can cause localized deformation of the polarizing film, thus affecting its production quality.

[0005] Based on this, a polarizer punching and collecting device is provided, which can eliminate the drawbacks of existing devices. Utility Model Content

[0011] In one alternative: a second cylinder is provided at the top of the first mounting frame, and a connecting frame is provided at the movable end of the second cylinder, the bottom of which is connected to the top of the upper receiving roller assembly.

[0012] In one alternative embodiment: the punching table is internally provided with multiple spring telescopic rods, the telescopic ends of which are connected to the bottom of the lower receiving roller assembly.

[0013] In one alternative: a drive motor is provided on the side wall of the lower take-up roller group, and a transmission belt is provided on the other side wall of the lower take-up roller group.

[0014] In one alternative: the punching table is internally equipped with a receiving box for collecting polarizing film master tape.

[0015] Compared with the prior art, the beneficial effects of this utility model are as follows: 1. This utility model uses a conveyor belt inside the punching table to transport the polarizing film master tape to a designated position. The lower pressure plate inside the second mounting frame drives the punching knife to complete the punching.

In this embodiment, the conveyor belt 12 inside the punching table 1 transports the polarizing film master tape to the designated position, the lower pressure plate 9 inside the second mounting frame 4 drives the punching blade 11 to complete the punching, the smoothing components on both sides of the lower pressure plate 9 smooth the polarizing film master tape, and the material collection component on one side of the conveyor belt 12 collects the material; to prevent the polarizing film master tape from being deformed due to lack of tension during punching. In one embodiment, such as Figure 2 As shown, the smoothing assembly includes rotating plates 7 rotatably disposed on both sides of the lower pressure plate 9. One end of the rotating plate 7 is rotatably disposed with a pressing roller 8 for smoothing the polarizer master tape. Multiple compression springs 10 are disposed on both outer walls of the lower pressure plate 9, and the other end of the compression spring 10 is connected to the side wall of the rotating plate 7. The rotating plates 7 on both sides of the lower pressure plate 9 move down with the lower pressure plate 9, the extrusion roller 8 contacts the polarizer tape and rolls it flat, and the compression spring 10 provides elastic support for the rotating plate 7 to ensure that the extrusion roller 8 fits the polarizer tape; by elastically pressing and flattening the polarizer tape, wrinkles in the polarizer tape before punching are avoided, and punching errors are reduced.

[0025] In one embodiment, such as Figure 2 As shown, a first cylinder 5 is provided on the top of the second mounting bracket 4, and the movable end of the first cylinder 5 is connected to the top of the lower pressure plate 9. The first cylinder 5 at the top of the second mounting bracket 4 drives the movable end to extend and retract, causing the lower pressure plate 9 to move up and down; providing stable power for the punching blade 11 and the smoothing assembly, ensuring uniform punching force and improving punching accuracy.

[0026] In one embodiment, such as Figure 3 As shown, the receiving assembly includes a first mounting frame 2 disposed on the top of the punching table 1, and an upper receiving roller group 13 and a lower receiving roller group 14 for receiving materials are movably disposed inside the first mounting frame 2.
