Description

Single-shaft rotating and bending mechanism
Technical Field
The invention relates to the field of curved surface display panel manufacturing equipment, in particular to a single-shaft rotating and bending mechanism.
Background
The curved screen is a display screen made of flexible plastic and is mainly realized by an OLED panel. Compared with a straight screen, the curved screen has better elasticity and is not easy to break. Curved surface screen uses non-rigid glass as the base, and the elasticity is better, is difficult for broken. The abrasion probability of the screen is reduced, and particularly the screen of the mobile phone with higher touch rate is reduced. When the curved-surface screen is used for a mobile phone, the overall curved design of the curved-surface screen is beneficial to holding, the curved-surface screen is better attached to the palm radian, the distance of a thumb touching the screen when the curved-surface screen is operated by a single hand is reduced, and the experience of transverse screen-crossing operation under a large-size screen is theoretically promoted; the subtle curves allow the phone holder to have better privacy of information, such as the person sitting beside not being able to see what is displayed on the phone screen. The screen can be made thinner, light-weight, and low-power. The curved screen increases the angle of visibility, so the effect is good even when viewed at an off-center angle. The curved surface is not only subversion of the appearance form of the television, but also significant improvement of the watching comfort, and is a great step of the development of the appearance of the television. And simultaneously, the method is a test and challenge for the manufacturer technology.
Since the flexible display panel has the characteristics of thinness, lightness and flexibility, the application of the flexible display panel tends to be diversified. The flexible display panel can be folded or rolled to reduce the occupied space. In the case of the bending manner, the tension applied to the flexible display panel must be controlled, the flexible display panel itself cannot be pressed to cause permanent creases, and the flexible display panel needs to be supported over the entire surface when in use.
Therefore, a bending mechanism capable of effectively avoiding crease caused by extrusion when bending is needed.

The main difference between the fourth single-shaft rotating bending mechanism and the first single-shaft rotating bending mechanism is that different movement postures are respectively completed through the first bearing plane 1 and the second bearing plane 6, so that the bending is performed in cooperation, the structure of the bending equipment and the difficulty of a transmission structure are greatly simplified, and the overall cost is reduced simultaneously on the premise of ensuring the quality.
In summary, the present invention is directed to provide a single-axis rotation bending mechanism, which can prevent the screen from being subjected to stress concentration caused by extra tension and pressure and non-tangency, effectively avoid the generation of creases, and improve the overall quality of the curved screen product.
The foregoing is a more detailed description of the invention in connection with specific preferred embodiments and it is not intended that the invention be limited to these specific details. For those skilled in the art to which the invention pertains, several simple deductions or substitutions can be made without departing from the spirit of the invention, and all shall be considered as belonging to the protection scope of the invention.
