Background Art

[0002] With the continuous advancement and innovation of the technological age, many aspects of daily life have also undergone significant changes. For example, the images presented on screens, such as television and movies, have evolved from early two-dimensional (2D) flat images to three-dimensional (3D) stereoscopic images, satisfying people's different stereoscopic visual perceptions. Furthermore, with the stereoscopic visual effects presented by three-dimensional (3D) images, many industries are utilizing 3D stereoscopic images to create various realistic and immersive simulated image realms. For example, virtual reality (VR), augmented reality (AR), mixed reality (MR), and cinematic reality (CR) technologies are being applied in various games, television programs, and movies, providing people with the visual experience of watching 3D images.

[0003] 3D image presentation utilizes binocular parallax, a phenomenon in which the different positions and viewing angles of the two eyes result in slightly different images. Ultimately, the brain adjusts and integrates these different images to produce a 3D image. Stereoscopic image presentation technologies can be broadly categorized into stereoscopic (requiring specially designed glasses for viewing) and autostereoscopic (requiring glasses for viewing without glasses). Stereoscopic 3D image display technologies can be further subdivided into chromatic aberration (i.e., color filter glasses), polarizing (i.e., polarizing glasses), and active shutter (i.e., shutter glasses). Polarized 3D imaging technology (i.e., polarization) is a type of 3D image presentation technology that uses a chromatic aberration lens to create a 3D image. 3D), also known as polarized 3D stereo imaging technology, uses the vibration direction of light to decompose the original image. The image is first divided into two groups of pictures: vertically polarized light and horizontally polarized light. Then, the left and right lenses of the 3D glasses use polarized light lenses with different polarization directions respectively, so that the user's left and right eyes can receive the two groups of pictures respectively through the left and right lenses, and then the brain synthesizes them to form a three-dimensional image.

[0004] Furthermore, with naked-eye stereoscopic image presentation, users can view 3D images without the need for specially designed glasses. For example, lenticular lens-type stereoscopic display technology utilizes lenses to direct the light waves of each display information to the viewer's left and right eyes. However, the resulting stereoscopic images are subject to positional and angular limitations, thus limiting the viewer's viewing position and angle. In contrast, the use of specially designed glasses with these limitations is still widely adopted. However, polarized glasses must be inspected and aligned to ensure the proper polarization angle and polarization direction of the left and right lenses to achieve a good 3D image display. Otherwise, the transmission axis (the axis that transmits linearly polarized light) of the polarized glasses may tilt during use, leading to crosstalk, resulting in brightness variations and dimming.

[0005] During the manufacturing and assembly process, general optical lenses may undergo various processing procedures such as grinding, film application, alignment, correction and assembly. In particular, during the film application process, it is necessary to ensure that the lens surface is intact and free of scratches or cracks. In other words, the film must be applied to the lens surface flatly and without wrinkles to protect the lens surface from external damage. Otherwise, if the film application is uneven on the lens surface, it will affect the deviation or error of other subsequent processing steps and lead to an increase in product defect rate. These defects need to be improved.

[0006] Therefore, how to solve the problems and drawbacks in the current lens processing process, such as ensuring the integrity of the lens surface to avoid scratches or cracks, and the need to keep the lens surface flat and wrinkle-free, which leads to processing inconveniences, is the direction that manufacturers engaged in this industry are eager to research and improve.

A base body 15 is provided between the outside of the lifting frame 12 and the fixed frame 13, and the lifting frame 12 can be movably assembled. At least two lifting rods 121 are provided at the bottom of the lifting frame 12, which can be movably provided at the base body 15 and can be lifted and lowered in the longitudinal direction. The base 1 is set on the working machine 3, and the lifting frame 12 and the suction frame 14 of the base 1 can be controlled by the working machine 3 to start operation.

[0031] Furthermore, the positioning unit 2 of the present invention includes a disc seat 22 arranged around the outside of the base 1, and a plurality of control machines 221 arranged on the disc seat 22 surrounding the outside of the base 1, and each control machine 221 is provided with a clamping arm 21 located above the fixed frame 13, that is, each control machine 221 controls each clamping arm 21 to swing in a fan shape above the fixed frame 13 to clamp or release the diaphragm 141.

[0032] The base 1 can be covered with a cover 4 on the fixing frame 13 and the diaphragm 141, and the periphery of the diaphragm 141 is positioned on the top of the fixing frame 13. A vacuum state is formed inside the cover 4, and the heating unit 5 can be positioned above the base 1 to heat and increase the temperature of the diaphragm 141 to soften the diaphragm 141. The heating unit 5 can be a far-infrared heater, an ultraviolet heater, a ceramic heater, a temperature sensor, an electric heating plate heater, or an electric heating tube heater.

[0033] Furthermore, see Figures 1 to 11 As shown, the laminating method of the laminating device of the present invention includes a base 1 and a positioning unit 2 located around the base 1, and can be implemented according to the following steps:

[0034] (A01) The supporting portion 111 on the support frame 11 of the base 1 supports the preset lens 112.

[0035] (A02) The membrane 141 is moved to the top of the base 1 by using the adsorption rack above the base 1 and aligned with the preset lens 112.

[0036] (A03) The adsorption frame 14 releases the adsorption force on the membrane 141 so that the membrane 141 is placed above the outermost fixing frame 13 of the base 1.

[0037] (A04) The periphery of the diaphragm 141 above the fixing frame 13 is clamped by a plurality of clamping arms 21 using the positioning unit 2 outside the fixing frame 13 .

[0038] (A05) The external lifting frame 12 of the support frame 11 of the base 1 rises, and the diaphragm 141 supported above the base 1 rises.

[0039] (A06) The cover 4 is then used to cover the fixing frame 13 and the diaphragm 141 from above the base 1, and the periphery of the diaphragm 141 is positioned on the top of the fixing frame 13, so that a vacuum state is formed inside the cover 4.

[0041] (A08) The plurality of clamping arms 21 of the positioning unit 2 are withdrawn from the periphery of the fixing frame 13 to allow external pressure to enter the interior of the cover body 4 to loosen the diaphragm 141.

[0042] (A09) The lifting frame 12 outside the support frame 11 is lowered longitudinally to allow the loosened film 141 to be attached downwardly above the preset lens 112 located on the support frame 11.

[0043] (A10) The film sheet 141 is attached to the surface of the preset lens 112.

[0044] (A11) The lamination process of the diaphragm 141 is completed.

[0045] The preset lens 112 with the film applied can then be processed in the subsequent steps.

[0046] Furthermore, in the above-mentioned step (A07), the film 141 is heated by the heating unit 5, which can provide the film 141 with advantages such as softening and ductility. When the film 141 is to be attached to the preset lens 112, it can be smoothly attached to the curvature of the surface of the preset lens 112, achieving the purpose of smooth attachment and less prone to wrinkles.

[0047] The heating unit 5 can be a far-infrared heater, an ultraviolet heater, a ceramic heater, a temperature sensor, an electric heater, or an electric heating tube heater, etc., which can heat and increase the temperature of the diaphragm 141.
