The present invention provides a laminating device and method, particularly a laminating device and method for quickly laminating a film. A positioning unit is provided on the exterior of a base. Multiple clamping arms of the positioning unit can clamp or release the film on the base, thereby achieving the purpose of laminating the film to a predetermined lens without causing wrinkles.

With the continuous advancement and innovation of the technology era, many things in daily life have also changed significantly with the advancement of technology. For example, the images displayed on the screen of the TV or movies that people watch in daily life have also changed from the early two-dimensional flat images (2D flat images, Two Dimension) to three-dimensional stereoscopic images (3D stereoscopic images, Three Dimension) to meet people's different feelings about the three-dimensional visual images when watching images. With the three-dimensional visual effect presented by the three-dimensional image (3D stereoscopic image) screen, many companies use 3D stereoscopic images to interpret various different real presence and immersive simulated image realms, such as virtual reality (VR) technology, augmented reality (Augmented Reality) technology, and so on. Augmented Reality (AR) technology, mixed reality (MR) technology, or cinematic reality (CR) technology, among others, have become technologies applied in various games, television, and movies, providing people with the visual experience of viewing 3D stereoscopic images.

The presentation of 3D images utilizes binocular parallax, a phenomenon in which the two eyes see slightly different images due to their different positions and viewing angles. Ultimately, the brain adjusts and integrates these different images to create a 3D image. Stereoscopic image presentation technologies can be broadly categorized as either stereoscopic (requiring specially designed glasses for viewing) or autostereoscopic (requiring glasses for viewing without glasses). Spectacle-based 3D image display technologies are further categorized into chromatic aberration (i.e., color filter glasses), polarizing (i.e., polarizing glasses), and autostereoscopic (requiring glasses for viewing without glasses). There are various types of 3D glasses, including those with active shutters (also known as shutter glasses). Polarization 3D, also known as polarization 3D stereoscopic imaging technology, utilizes the oscillation characteristics of light to decompose the original image, first splitting the image into two sets of images: vertically polarized light and horizontally polarized light. The left and right lenses of the 3D glasses then use polarized light with different polarization directions, allowing the user's left and right eyes to receive the two sets of images respectively. The brain then synthesizes these two sets of images to form a 3D image.

Furthermore, the stereoscopic image presentation for naked eye viewing does not require the user to wear specially designed glasses to view 3D stereoscopic images. For example, lenticular LENS type stereoscopic display technology uses a lens to direct the light sine waves of each display information to the viewer's left and right eyes respectively. The displayed stereoscopic image has position and angle restrictions, so the viewer's viewing position and angle are also subject to more restrictions. In contrast, the position or angle restrictions of viewing with specially designed glasses are still used by most manufacturers. However, polarized glasses must be tested. Measurement and alignment are performed to adjust the polarization angle and polarization direction of the left and right lenses to achieve a good 3D image display. Otherwise, the polarized glasses can easily tilt due to the transmission axis (the axis that transmits linear polarized light) during use, causing crosstalk and resulting in brightness variations and darkening of the polarized glasses.

Optical lenses typically undergo various manufacturing and assembly processes, including grinding, laminating, alignment, calibration, and assembly. During the laminating process, the lens surface must be intact and free of scratches and cracks. This means the film must be applied flat and wrinkle-free to the lens surface to protect it from external forces. Otherwise, uneven laminating can lead to deviations or errors in subsequent processing steps, increasing product defect rates and other defects that require improvement.

Therefore, manufacturers in this industry are urgently seeking solutions to the current challenges and challenges of lens manufacturing, such as ensuring the integrity of the lens surface to avoid scratches and cracks, and maintaining a flat, wrinkle-free surface during film application, which can lead to processing inconveniences.

Therefore, in light of the above-mentioned problems and deficiencies, the inventor collected relevant information, conducted extensive evaluations and considerations, and, drawing on years of experience accumulated in this industry, through continuous innovation and modification, finally designed and patented this bonding device and bonding method.

The primary purpose of this invention is to provide a laminating device and laminating method comprising a base and a positioning unit disposed around the base. The base comprises a support frame, a lifting frame disposed externally of the support frame, and a fixed frame disposed externally of the lifting frame. A suction frame is disposed above the fixed frame to hold a film sheet above the base for vertical elevation. The positioning unit is located externally of the fixed frame of the base and is equipped with a plurality of clamping arms to clamp or release the film sheet placed on the fixed frame. A cover is then placed over the base and film sheet, and a heating unit applies heat to soften the film sheet before it is attached to the lens. This ensures a stable and wrinkle-resistant film sheet, making subsequent processing easier.

Another object of the present invention is that the base is circular in shape, with a supporting portion provided above the support frame for carrying a pre-set lens. A circular lifting frame is provided on the outside of the support frame, and a base is provided between the outside of the lifting frame and the fixed frame to allow for movable assembly of the lifting frame. The base is provided with at least two lifting rods movably mounted on the base for longitudinal movement. The base is mounted on a work machine, and the lifting frame and suction frame of the base can be activated by the work machine. A positioning unit is provided on the outer periphery of the fixed frame.

Another object of the present invention is that the positioning unit comprises a disc seat mounted on the outside of the base, and a plurality of control machines mounted on the disc seat and surrounding the outside of the base. Each control machine is provided with a clamping arm positioned above a fixed frame. In other words, each control machine controls each clamping arm positioned above the fixed frame to swing in a fan-shaped manner to clamp or release the diaphragm.

Another object of the present invention is to provide a bonding method for the bonding device, which includes a base and a positioning unit located on the periphery of the base, which can support a preset lens on the support frame of the base; and using the adsorption frame above the base to transfer the film to the top of the base and align it with the preset lens; the adsorption frame releases the adsorption force on the film so that the film can be placed on the top of the fixed frame of the base; the positioning unit on the outside of the fixed frame uses a plurality of clamping arms to clamp the periphery of the film above the fixed frame; the lifting frame outside the support frame of the base rises to support the film above the base; and then the cover is used to lift the film. The housing is placed over the base, covering the fixed frame and diaphragm. The periphery of the diaphragm is positioned at the top of the fixed frame, creating a vacuum inside the housing. A heating unit located above the housing heats the diaphragm to soften it. The multiple clamping arms of the positioning unit are retracted from the periphery of the fixed frame, allowing external pressure to enter the housing to loosen the diaphragm. A lifting frame on the outside of the support frame descends vertically, allowing the loosened diaphragm to adhere to the pre-set lens on the support frame. The diaphragm adheres to the surface of the pre-set lens, completing the diaphragm bonding process.

Another object of the present invention is to enable the suction rack to absorb or release the film through vacuum suction or suction using multiple suction cups.

The base 1 of the present invention can be circular in shape, with a support portion 111 disposed above the support frame 11 for supporting a preset lens 112. A circular lifting frame 12 is disposed on the outside of the support frame 11. A base 15 is disposed between the outside of the lifting frame 12 and the fixed frame 13, allowing for movable assembly of the lifting frame 12. At least two lifting rods 121 are disposed at the bottom of the lifting frame 12, movably mounted on the base 15 for longitudinally movable lifting and lowering. The base 1 is mounted on a workbench 3, and the lifting frame 12 and suction frame 14 of the base 1 can be activated and operated by the workbench 3.

Furthermore, the positioning unit 2 of the present invention comprises a circular disc 22 disposed around the exterior of the base 1. A plurality of control machines 221 are mounted on the circular disc 22 and surround the exterior of the base 1. Each control machine 221 is provided with a clamping arm 21 positioned above the fixing frame 13. Specifically, each control machine 221 controls each clamping arm 21 above the fixing frame 13 to swing in a fan-shaped manner to clamp or release the diaphragm 141.

The base 1 is covered with a cover 4 over the mounting frame 13 and the diaphragm 141. The periphery of the diaphragm 141 is positioned on top of the mounting frame 13, and a vacuum is created inside the cover 4. The heating unit 5 is then aligned with the base 1 to heat and increase the temperature of the diaphragm 141, thereby softening it. The heating unit 5 can be a far-infrared heater, ultraviolet heater, ceramic heater, temperature sensor, electric heating plate heater, or electric heating tube heater, etc.

Furthermore, referring to Figures 1-11, 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:

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

(A02) Use the suction rack above the base 1 to move the film 141 to the top of the base 1 and align it with the preset lens 112.

(A03) The adsorption frame 14 releases its adsorption force on the diaphragm 141, allowing the diaphragm 141 to be placed on the outermost fixing frame 13 of the base 1.

(A04) The positioning unit 2 on the outer side of the fixing frame 13 is used to clamp the periphery of the diaphragm 141 above the fixing frame 13 with multiple clamping arms 21.

(A05) The external lifting frame 12 of the base 1 is raised by the support frame 11, and the diaphragm 141 located above the base 1 is lifted.

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

(A07) The heating unit 5 located above the cover 4 is used to heat the diaphragm 141 to soften the diaphragm 141.

(A08) Move the multiple clamping arms 21 of the positioning unit 2 away from the periphery of the fixing frame 13 to allow external pressure to enter the interior of the cover 4 to loosen the diaphragm 141.

(A09) The lifting frame 12 on the outside of the support frame 11 is lowered vertically, allowing the loosened film 141 to adhere downward to the preset lens 112 located on the support frame 11.

(A10) The film 141 is bonded to the surface of the preset lens 112.

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

The pre-set lens 112 with the film applied can then proceed to subsequent processing.

Furthermore, the aforementioned step (A07) heats the film 141 via the heating unit 5, which softens and imparts ductility to the film 141. Furthermore, when the film 141 is attached to the predetermined lens 112, it can smoothly conform to the curvature of the surface of the predetermined lens 112, achieving a smooth fit and preventing wrinkles.

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, etc., and can heat and increase the temperature of the diaphragm 141.
