[0025] 3. Before the optical film with the protective film torn off is transferred to the pressing loading and unloading device through the material transfer assembly, the utility model first transfers the optical film to the pre-forming lower cavity and the pre-forming upper cavity, and cooperates with the heating of the second heating lamp, the shape of the molding fixture and the vacuum environment to pre-form the optical film into a shape similar to or the same as the curvature of the lens, so that the optical film can be better bonded to the lens during the formal bonding in the molding and bonding device, thereby improving the efficiency and quality of the film bonding and reducing the occurrence of wrinkles and voids.

[0058] like Figure 1 — Fig.17 The embodiment shown.
[0059] See also Fig.17 As shown, in the initial state, a protective film and a carrier film are respectively provided on the upper and lower sides of the optical film.

[0061] See also Figure 1 As shown, first, the optical film is transferred to the film tearing position by the film tearing and loading and unloading device 2, and the protective film on its surface is torn off. After tearing off, the optical film is transferred to the loading position of the transfer component 5, and then the transfer component 5 transports the lens from the lens loading platform 6 to the pressing and unloading device 4, and then the transfer component 5 transports the optical film with the protective film torn off to the loading position of the pressing and unloading device 4. At this time, the lens and the optical film are both located on the pressing and unloading device 4, and the pressing and unloading device 4 transports the optical film and the lens to the position of the molding and bonding device 3, and then the molding and bonding heating component 34 in the molding and bonding device 3 heats the optical film, so that the optical film can be bent with a larger curvature, reducing the appearance of wrinkles and voids.

[0063] See also Figures 2 to 4In the initial state, the first carrier 22 carries an optical film (with a protective film and a carrying film). At this time, the protective film is located on the lower surface of the optical film, and the carrying film is located on the upper part. The first linear module 21 moves the optical film on the first carrier 22 to the unloading position, and then the first adsorption and transfer component 23 adsorbs and transfers the optical film to the position of the film tearing component 24. The protective film on the lower surface of the optical film is torn off through the cooperation of the film tearing component 24 and the first adsorption and transfer component 23 to achieve film tearing. The torn protective film is thrown into the waste basket 25 for collection. The first adsorption and transfer component 23 transports the optical film back to the first carrier 22. During the transportation process, the optical film passes through the first wind knife 26 for dust removal to prevent dust from being on the optical film.
[0064] The first adsorption transfer component 23 includes a first two-axis movable module 231, a first rotating cylinder 232 is installed at the movable end of the first two-axis movable module 231, a first fixed plate 233 is fixedly installed at the rotating end of the first rotating cylinder 232, and a plurality of first suction cups 234 for adsorption are fixedly installed on the first fixed plate 233.
[0065] The film tearing assembly 24 includes a second rotating cylinder 241, a clamping cylinder 242 is fixedly installed on the rotating end of the second rotating cylinder 241, a clamping claw 243 is installed on the clamping end of the clamping cylinder 242, a fixing frame 244 is fixedly installed on the frame 1 on one side of the clamping cylinder 242, a rubber roller 245 is rotatably installed on the upper surface of the fixing frame 244 through a mounting seat, a moving cylinder 246 is fixedly installed on the end of the bottom surface of the fixing frame 244 close to the clamping cylinder 242, a clamping block 247 is installed on the moving end of the moving cylinder 246, and an extending end of the clamping block 247 is located on the side of the rubber roller 245 close to the clamping cylinder 242.

In order to adapt to optical films of different shapes, the first rotating cylinder 232 drives the first fixed plate 233 and the first suction cup 234 to rotate, so as to adapt to optical films of different angles. Next, the first two-axis moving module 231 transfers the optical film adsorbed by the first suction cup 234 to the position of the rubber roller 245, and makes the protective film on the lower surface of the optical film contact with the rubber roller 245 at this time. When in contact, the rubber roller 245 adheres to the corners of the protective film. At this time, a certain gap will appear at the corners of the protective film. The moving cylinder 246 drives the clamping block 247 to move towards the direction close to the rubber roller 245, and the clamping block 247 resists the protective film adhered to the rubber roller 245, so that the adhered protective film and The rubber roller 245 is fixed. At this time, since the rubber roller 245 is in contact with the clamping block 247, the rubber roller 245 does not rotate. As the first two-axis moving module 231 drives the optical film adsorbed by the first suction cup 234 to move, the optical film and the protective film move relative to each other, so that the protective film on the bottom surface is separated from the optical film, and the film is peeled off. After the film is peeled off, the torn protective film will bend to a certain extent under the action of gravity. Next, the clamping cylinder 242 drives the two clamping claws 243 to approach each other to clamp the protective film, and then the moving cylinder 246 drives the clamping block 247 to move to release the state of resistance to the rubber roller 245. The second rotating cylinder 241 drives the protective film clamped by the clamping claws 243 to rotate above the waste basket 25. At this time, the protective film is separated from the rubber roller 245, and the clamping cylinder 242 drives the clamping claws 243 to release the clamping of the protective film, so that the protective film is thrown into the waste basket 25.

After the temperature reaches the predetermined requirement, the first heating lamp 344 stops heating, and the molding and bonding upper chamber 31 is filled with positive pressure air through the inflation pipeline and the passage of the first inflation hole stroke. Under the action of the air pressure difference, the optical film and the lens are fully contacted and bonded.

The vacuuming step can be operated by the corresponding vacuum generator, and the vacuuming, filling and deflation operations can be realized through the linkage between the air compressor, the vacuum generator and the air circuit. The specific air circuit can be designed according to needs and is not limited here.
[0082] Some existing devices for attaching optical films usually only adhere the optical film through the pressure difference between negative pressure and atmospheric pressure in the form of vacuum pressure. However, the bonding effect cannot meet the expected effect due to pressure and other reasons. For this reason, the present application performs positive pressure bonding on one side and negative pressure on the other side. The pressure difference between positive pressure and negative pressure is used to achieve the bonding of the optical film under high pressure.
[0083] The preforming device 8 includes a preforming lower chamber 81 and a preforming upper chamber 82.

A second linear module 84 is arranged below the preforming lower chamber 81 to drive it to move directly below the preforming upper chamber 82. A moving plate 85 is installed at the moving end of the second linear module 84. The molding lower chamber 81 is fixedly mounted on the upper surface of the movable plate 85, and the preforming device 8 also includes a lifting drive assembly 89 for driving the preforming upper chamber 82 to rise and fall; a second positioning CCD88 is also provided on the upper surface of the frame 1, and a second inflation hole for filling positive air is provided on the back of the preforming lower chamber 81, and a second exhaust hole for vacuuming is provided on the back of the preforming upper chamber 82, and the second exhaust hole is connected to an exhaust pipe 812, and a third horizontal plate 815 is provided on one side of the back of the preforming lower chamber 81, and an inflation nozzle 811 adapted to the second inflation hole is provided on the side of the third horizontal plate 815 close to the direction of the preforming lower chamber 81.

[0085] See also Fig.14 and Fig.16 As shown, in order to ensure the bonding quality in the molding process, the optical film is first pre-molded into a shape that matches the lens, and then bonded to the lens through formal molding, thereby improving the molding quality.
[0086] Specifically, first, the third adsorption and transfer component 53 positions the optical film with the protective film torn off through the second positioning CCD88, and then transfers it to the upper surface of the pre-molded lower cavity 81 to adsorb and fix the optical film through the second fixed suction cup 86. At this time, the supporting film is located on the upper surface of the optical film, and the movable plate 85 drives the optical film on the upper surface of the pre-molded lower cavity 81 to move to the bottom of the pre-molded upper cavity 82. The second inflation hole on the back of the pre-molded lower cavity 81 is tightly fitted and sealed with the inflation nozzle 811. The lifting drive component 89 drives the pre-molded upper cavity 82 to seal with the pre-molded lower cavity 81. The interior of the pre-molded upper cavity 82 is evacuated through the exhaust pipe 812, and the interior of the pre-molded lower cavity 81 is evacuated through the inflation nozzle 811. During the vacuuming process, the second vacuum gauge 814 performs real-time detection of the vacuum value of the cavity formed by the pre-molded lower cavity 81 and the pre-molded upper cavity 82 until it reaches a predetermined value. Then the second heating lamp 87 passes through the pre-molded The bottom window of the lower cavity 81 heats the optical film inside it. During this process, the second temperature sensor 813 detects the temperature in real time. When the temperature reaches the predetermined value, the lifting drive assembly 89 drives the molding jig 83 to move closer to the heated optical film and contact the supporting film on the upper surface of the optical film. Next, the pre-molding lower cavity 81 is inflated by the inflation nozzle 811. Under the action of the air pressure difference between the pre-molding lower cavity 81 and the pre-molding upper cavity 82, the heated optical film and the supporting film are pressed against the molding jig 83, so that the optical film is formed into a shape that matches the molding jig 83. In this embodiment, the shape of the molding jig 83 can be the same as or similar to the shape of the lens, so as to facilitate the subsequent molding and bonding device 3 to mold the lens and the optical film tightly. Compared with one-time pressing and bonding, pre-molding before pressing and bonding can improve the success rate of pressing and bonding and reduce the generation of wrinkles and voids.
[0087] In the present application, an external air compressor is used to provide corresponding positive pressure air to the inflation nozzle 811, and a vacuum generator is used to provide negative pressure air for the vacuum step to form negative pressure. In the present embodiment, the air compressor and vacuum generator that provide positive pressure and negative pressure in the preforming device 8 can be the same as the forming and bonding device 3, and the same components are used to provide positive pressure and negative pressure. Accordingly, the pressure values of positive pressure and negative pressure can be set and adjusted according to needs, and there is no limitation here.
[0088] In this embodiment, the second heating lamp 87 and the first heating lamp 344 are both IR lamps.

[0091] A first snap-fit fixing structure 9 for fixing is arranged between the forming and bonding device 3 and the pressing and loading and unloading device 4, and between the pre-forming upper cavity 82 and the pre-forming lower cavity 81. The first snap-fit fixing structure 9 includes a first snap-fit plate 91. A first snap-fit driving cylinder 93 is hingedly installed at the driving end of the first snap-fit plate 91. A first snap-fit block 92 is arranged at the snap-fit end of the first snap-fit plate 91. When in use, the first snap-fit driving cylinder 93 drives the first snap-fit plate 91 to rotate so that the snap-fit end is snapped with the first snap-fit block 92.
[0092] See also Fig.11 and Fig.16 As shown, in the present application, after the molded bonding lower cavity 45 and the molded bonding upper cavity 31 are bonded, the two are fixed by the first snap-fit fixing structure 9. Similarly, after the pre-molded lower cavity 81 and the pre-molded upper cavity 82 are bonded, the two are also fixed by the first snap-fit fixing structure 9. Specifically, when fixing, first, the first snap-fit driving cylinder 93 drives one end of the first snap-fit plate 91 to move. Then, under the action of the hinge shaft, the other end of the first snap-fit plate 91 moves toward the direction close to the first snap-fit block 92 and snaps into place, thereby achieving a fixing effect.
[0093] A second snap-fit fixing structure 10 for fixing the movable plate 85 is installed on the second sealing bellows 810, and the second snap-fit fixing structure 10 includes a hinged seat 101 fixedly installed on the side of the second sealing bellows 810, and a second snap-fit driving cylinder 102 is hingedly installed on the hinged seat 101.

A second snap-fit block 104 that can snap with the second snap-fit plate 103 is fixedly installed on the movable plate 85.
[0094] See also Fig.16 As shown, when the pre-molding lower cavity 81 is transferred to the position directly below the pre-molding upper cavity 82, the second snap-fitting driving cylinder 102 drives the second snap-fitting plate 103 to move downward, so that the second snap-fitting plate 103 snaps onto the second snap-fitting block 104 on the movable plate 85, thereby fixing the position of the movable plate 85 and preventing it from moving.
[0095] A useful detection component 11 is arranged between the molding and laminating device 3 and the pressing and loading and unloading device 4.

A UV lamp 114 is fixedly installed on the other side of the cross bar of the detection frame 111.
[0096] Since the glue area of the film carrier is larger than the position of the lens, in order for the glue to adhere to the finished product unloading carrier, the UV lamp 114 is used to deglue it to prevent the glue from adhering to the carrier.
[0097] See also Figure 7 As shown, in order to ensure the optical effect of the optical film and the lens after molding and bonding, the upper detection sensor 112 and the lower detection sensor 113 cooperate to detect the positional relationship between the lens and the optical film in real time, see Figure 8It can be seen that the optical film is adsorbed and fixed on the molded and bonded lower cavity 45, and the lens is located on the carrier 47, that is, the lens on the carrier 47 can rotate relative to the optical film on the molded and bonded lower cavity 45, and the carrier 47 and the DD motor 44 and the middle of the first lifting plate 42 are all hollow, so that the detection light of the lower detection sensor 113 can pass through the lens and optical film located on the carrier 47 to the upper detection sensor 112, so as to realize the detection of corresponding data. During the detection process, the lens on the carrier 47 can be mobilized by the DD motor 44 to rotate relative to the optical film, so as to stop rotating until the optical effect between the two reaches the maximum value. The detected optical data can be a scattering effect, a focusing effect, etc. The sensors used by the upper detection sensor 112 and the lower detection sensor 113 can be adaptively selected according to the detection of different data. There is no specific restriction on the type of optical effect and the type of sensor here.
