Technical Field

[0001] The utility model relates to the field of polarizer peeling, in particular to a polarizer peeling mechanism. Background Art

[0002] The rapid development of liquid crystal display technology in today's scientific and technological field has not only profoundly changed people's lifestyles, but also promoted innovation and progress in many industries. From smartphones and tablets to high-definition televisions, car displays, and even high-end application fields such as medical imaging and aerospace, liquid crystal display technology has won wide favor in the market with its advantages such as excellent display effects, low power consumption and long life.

[0003] The widespread application of liquid crystal display technology in many fields and the introduction of new technologies have placed increasingly higher demands on the production process of liquid crystal display panels. In the post-production manufacturing of the flat panel display industry, polarizer attachment is a key process, so patching is one of the key processes that affects product quality and production efficiency. After the common patching process is prepared, auxiliary tools are used to ensure that the polarizer is perfectly fitted without bubbles or wrinkles to meet the optical performance and stability requirements of the display device.

[0004] Due to factors such as material properties, process parameters or equipment limitations, the release film of existing patch process equipment is often difficult to peel off smoothly, which not only affects production efficiency, but may also lead to poor polarizer attachment. In response to the defect that the polarizer release film is difficult to peel off in existing patch process equipment, a polarizer release film peeling mechanism is designed. The present invention utilizes a combination of a backing plate and an adhesive tape to achieve rapid peeling of the polarizer release film, effectively solving the problem of difficult peeling of the polarizer release film, improving the polarizer attachment efficiency and yield, and the entire process has a high degree of automation. Utility Model Content

[0006] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a polarizer peeling mechanism, including a peeling mechanism and a patch glue roller, the outer wall of the peeling mechanism is equipped with a tape output roller, and the outer wall of the peeling mechanism is equipped with a moving roller, the outer wall of the peeling mechanism is equipped with a peeling back plate that provides support and guidance for the tape during the peeling process, and the outer wall of the peeling mechanism is equipped with a tape collecting roller for fixing the tape, the outer wall of the peeling mechanism is equipped with a tape pressing roller for tightening the tape, and the outer wall of the peeling mechanism is equipped with a servo motor.

[0007] By adopting the above technical solution, the polarizer release film can be quickly peeled off by using the backing plate in combination with the adhesive tape, which effectively solves the problem of the polarizer release film being difficult to peel off and improves the polarizer attachment efficiency and yield.

[0008] Furthermore, a transparent tape for conveying the release film is installed on the outer wall of the stripping mechanism, and the transparent tape is fixedly connected to the tape collecting roller.

The peeled release film and transparent tape will be collected in an orderly manner by the tape collecting roller, ensuring a neat and efficient peeling process.

[0010] Furthermore, a stepping motor for driving the peeling and retracting plate is installed on the outer wall of the peeling mechanism, and a first cylinder for driving the belt pressing roller is installed on the outer wall of the peeling mechanism.

[0011] By adopting the above technical solution, it is beneficial to accurately drive the peeling and retracting plate to move through the stepper motor, and provide appropriate tension and control for the transparent tape through the first cylinder during the peeling process, thereby improving the peeling efficiency and ensuring the automation and accuracy of the entire peeling process, thereby improving the overall production efficiency and product quality.

[0012] Furthermore, after the transparent tape is installed, the tape pressing roller is located outside the transparent tape.

[0013] By adopting the above technical solution, it is ensured that the tape pressing roller can effectively apply pressure to the transparent tape, thereby maintaining its stability and tension during the peeling process.

[0014] Furthermore, when the patch adhesive roller moves downward, the adhesive surface of the transparent adhesive tape abuts against the release film.

[0015] By adopting the above technical solution, the transparent tape can fully utilize its adhesive properties to effectively peel the release film from the object to which it is attached.

[0016] Furthermore, the servo motor is installed at the end of the stripping mechanism away from the tape collecting roller, and the patch adhesive roller is located above the stripping mechanism.

[0017] By adopting the above technical solution, the servo motor can stably drive the peeling mechanism, avoiding interference with other parts, and allowing the patch glue stick to smoothly contact the transparent tape when moving downward, thereby effectively peeling the release film.

[0026] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. The embodiments described below with reference to the drawings are exemplary and are only used to explain the present invention, and cannot be understood as limiting the present invention.

[0027] The following describes an embodiment of the present invention based on its overall structure.

[0028] A polarizer peeling mechanism, such as Figure 1 - Figure 5 As shown, it includes a peeling mechanism 1 and a patch glue roller 8. The outer wall of the peeling mechanism 1 is equipped with a tape output roller 2 for providing transparent tape for subsequent peeling operations, laying a solid foundation for the entire peeling process. In addition, the outer wall of the peeling mechanism 1 is equipped with a moving roller 3. The moving roller 3 adjusts the position of the transparent tape during the peeling process to ensure that the transparent tape can accurately cooperate with the peeling and retracting plate 4 and other components in the subsequent work.

[0029] In this embodiment, a peeling plate 4 is mounted on the outer wall of the peeling mechanism 1 to provide support and guidance for the tape during the peeling process. During the peeling process, the peeling plate 4 is in close contact with the tape. A tape collecting roller 5 is mounted on the outer wall of the peeling mechanism 1 to fix the tape. The tape collecting roller 5 collects the peeled transparent tape and, through rotation and appropriate tension adjustment, neatly winds up the transparent tape for subsequent reuse or disposal.

[0030] In the following example, a tape pressing roller 6 for tightening the tape is installed on the outer wall of the peeling mechanism 1. The tape pressing roller 6 is located on the outside of the transparent tape. By applying appropriate pressure, it ensures that the transparent tape maintains stable tension and position during the peeling process. A servo motor 7 is installed on the outer wall of the peeling mechanism 1. The servo motor 7 provides precise and controllable driving force for the peeling mechanism 1, ensuring the stability and accuracy of the peeling process.

[0031] See also Figure 1 - Figure 5 The outer wall of the peeling mechanism 1 is installed with a transparent tape for conveying the release film, and the transparent tape is fixedly connected to the tape collecting roller 5, which is conducive to using the adhesive properties of the transparent tape to assist in effectively peeling the release film from the polarizer. The peeled release film and transparent tape will be collected in an orderly manner by the tape collecting roller 5, ensuring the neatness and efficiency of the peeling process.

[0032] See also Figure 1 - Figure 5 A stepper motor for driving the peeling and retracting plate 4 is installed on the outer wall of the peeling mechanism 1, and a first cylinder for driving the tape pressing roller 6 is installed on the outer wall of the peeling mechanism 1, which is conducive to accurately driving the peeling and retracting plate 4 to move through the stepper motor. The first cylinder provides appropriate tension and control for the transparent tape during the peeling process, thereby improving the peeling efficiency, ensuring the automation and accuracy of the entire peeling process, and thus improving the overall production efficiency and product quality.

[0033] See also Figure 1 - Figure 5 After the transparent tape is installed, the pressing roller 6 is located outside the transparent tape, which ensures that the pressing roller 6 can effectively apply pressure to the transparent tape, thereby maintaining its stability and tension during the peeling process.

[0034] See also Figure 1 - Figure 5 When the patch glue stick 8 moves downward, the adhesive surface of the transparent tape abuts against the release film, so that the transparent tape can make full use of its adhesive properties and effectively peel off the release film from the object being adhered. The movement of the patch glue stick 8 also ensures a smooth and uniform peeling process, avoiding quality problems caused by uneven peeling.

[0035] See also Figure 1 - Figure 5 The servo motor 7 is installed at the end of the peeling mechanism 1 away from the tape collecting roller 5, and the patch glue roller 8 is located above the peeling mechanism 1, which is conducive to the servo motor 7 to stably drive the peeling mechanism 1, avoiding interference with other parts, and allowing the patch glue roller 8 to smoothly contact the transparent tape when moving downward, thereby producing an effective peeling effect on the release film.

[0036] The working principle of the present invention is as follows: when the polarizer peeling mechanism needs to be used to work on the polarizer, the servo motor 7 is first started to drive the peeling mechanism 1 to move in the Y direction. The peeling mechanism 1 is equipped with a transparent tape for conveying the release film, a tape output roller 2, a moving roller 3, a peeling plate 4, a tape collection roller 5, and a tape pressing roller 6. The tape passes from one end of the tape output roller 2 around the moving roller 3 and is fixedly connected to the tape collection roller 5 through the peeling plate 4. The peeling plate 4 is driven by a stepper motor installed on the outer wall of the peeling mechanism 1. The tape pressing roller 6 is driven by a first cylinder installed on the outer wall of the peeling mechanism 1 to press the tape. At this time, the tape is in a taut state, and the patch adhesive roller 8 moves downward to roll, causing the adhesive surface of the tape to contact the release film. Then, the peeling plate 4 moves to lift the release film, and the tape pressing roller 6 is released by the first cylinder. The tape collecting roller 5 drives the release film to move, and the polarizer release film is now peeled off.

[0037] Although embodiments of the present invention have been shown and described, these specific embodiments are merely explanations of the present invention and are not limitations on the present invention. The specific features, structures, materials, or characteristics described may be combined in a suitable manner in any one or more embodiments or examples. After reading this specification, those skilled in the art may make modifications, substitutions, and variations to the embodiments as needed without departing from the principles and purpose of the present invention, but as long as they are within the scope of the claims of the present invention, they are protected by patent law.
