[0039] Example

[0040] See also Figure 1-6As shown, the utility model provides a technical solution of a peeling device for producing functional optical films: a peeling device for producing functional optical films, comprising a base 1, support frames 2 are welded on both sides of the upper end surface of the base 1, a lifting component 3 is installed on the upper end of the support frame 2, and a peeling mechanism 4 is connected to the lower end of the lifting component 3, and a sliding component 5 is installed on the upper end surface of the base 1; the peeling mechanism 4 includes a tension sensor 401, a mounting seat 403, a first connecting rod 406 and a grip 410. The tension sensor 401 is installed at the lower end of the lifting component 3. The lower end of the force sensor 401 is connected to a bracket 402 and a mounting seat 403 by bolts. Both sides of the upper end surface of the mounting seat 403 are welded to the lower end of the bracket 402. A plurality of suction cups 404 are installed on the lower end surface of the mounting seat 403. The mounting seat 403 is slidably connected to a piston 405 at the upper end of the suction cup 404 by opening a through hole. The lower end of the first connecting rod 406 is rotatably connected to the upper end of the piston 405 by a pin shaft. The upper end of the first connecting rod 406 is rotatably connected to a second connecting rod 407 by a pin shaft. The second connecting rod 407 is rotatably connected to a third connecting rod 408 by a pin shaft. The other end of the three-link rod 408 is welded to the upper end surface of the mounting seat 403, and the second links 407 are connected by opening a through hole at the upper end of the second links 407 to install the control rod 409. The handle 410 is welded to the upper end of the second link 407 in the middle of the mounting seat 403. When suction is required, the peeling mechanism 4 is first pressed on one end of the lower film through the lifting component 3. When all the air in the suction cup 404 is squeezed out, the handle 410 is pressed downward, and the control rod 409 drives one end of all the second links 407 to be pressed downward. Under the guidance of the third link 408, the second links 407 are The other end of 407 rises accordingly, thereby driving the first connecting rod 406 and the piston 405 to rise. Since the negative pressure of the suction cup 404 is stronger after the piston 405 rises, the surface of the optical film has been firmly adsorbed by the suction cup 404 at this time. Through the peeling mechanism 4, the suction cup 404 can quickly and effectively adsorb the functional optical film during the peeling test, improve the adsorption effect, and improve the success rate and work efficiency of subsequent peeling. The tension used in the peeling process is recorded by the tension sensor 401 and transmitted to the external receiving device, which is convenient for later comparison.

[0041] The sliding assembly 5 includes a slide groove 501, a support rod 502 and a stripping groove 504. The slide groove 501 is arranged on the upper end surface of the base 1. The lower end of the support rod 502 is slidably connected to the slide groove 501 by installing a pulley. A sliding seat 503 is welded on the upper end of the support rod 502. The stripping groove 504 is arranged on the upper end of the sliding seat 503. When the stripping mechanism 4 starts to strip the optical film in the stripping groove 504, the stripping of the film will generate a horizontal traction force on the sliding seat 503. Therefore, the sliding seat 503 will move laterally in the slide groove 501 through the pulley to ensure that the film stripping position is always directly below the stripping mechanism 4. By setting the sliding assembly 5, it is ensured that the stripped part and the unstripped part of the optical film are always kept vertical during stripping, so that the tension data collected by the tension sensor 401 is more accurate, and the stripping efficiency and success rate of the optical film are further improved.

[0042] The lifting assembly 3 includes an installation box 301, a motor 302, a limit gear 305 and a tooth plate 306. The installation box 301 is welded on the upper end surface of the support frame 2. The motor 302 is welded to one side of the lower end surface inside the installation box 301 through a bracket. The output end of the motor 302 is connected to the driving gear 303 through a transmission shaft. The other side of the lower end of the installation box 301 is rotatably connected to the driven gear 304 through a pin shaft. The limit gear 305 is rotatably connected to both sides of the upper end of the installation box 301 through a pin shaft. The tooth plate 306 is meshed and connected between the driving gear 303, the driven gear 304 and the limit gear 305. The lower end of 06 is connected to the tension sensor 401 by bolts. When the stripping mechanism 4 needs to be lowered, the motor 302 is started. The motor 302 drives the tooth plate 306 to descend through the teeth of the driving gear 303, thereby driving the stripping mechanism 4 under the tooth plate 306 to descend. The driven gear 304 is located on the side of the tooth plate 306 away from the driving gear 303 to ensure that the tooth plate 306 will not tilt after being subjected to force. At the same time, the limit gears 305 located on both sides of the tooth plate 306 will also rotate with the movement of the tooth plate 306, further ensuring that the tooth plate 306 will not tilt. When the stripping mechanism 4 needs to be lifted, the motor 302 can be reversed.

[0043] Disposable pads 6 are slidably connected in the grooves on both sides of the stripping groove 504. The disposable pads 6 are used to stick the optical film to be stripped, and are easy to replace.

[0044] Limiting strips 7 for limiting the disposable pad 6 are movably installed on both sides of the sliding seat 503 through pin shafts. A clamping seat 701 matching the limiting strips 7 is welded on the outer walls on both sides of the sliding seat 503. The disposable pad 6 is placed along the notches on both sides of the peeling groove 504, and then the limiting strips 7 are transferred into the clamping seat 701 to limit the disposable pad 6, which can effectively prevent the disposable pad 6 from moving when peeling the optical film.

[0045] A limiting plate 307 is installed on the upper end of the tooth plate 306 , and the limiting plate 307 can effectively prevent the tooth plate 306 from falling off from the installation box 301 .

[0046] The surface of the handle 410 is provided with anti-skid particles, which can increase the surface friction of the handle 410 to prevent it from slipping during pressing.

[0047] The working principle of the utility model is as follows:

[0048] When using the peeling device for producing functional optical films of this embodiment, the disposable pad 6 is first placed along the notches on both sides of the peeling groove 504, and the limiting strips 7 are rotated into the holder 701 to limit the disposable pad 6. Then, the optical film to be peeled is glued to the upper end surface of the disposable pad 6 by glue, and the sliding seat 503 is pushed onto the base 1 along the slide groove 501, and the sliding seat 503 is pushed until the front end of the optical film is located directly below the suction cup 404, and then the motor 302 is started, and the motor 302 drives the driving gear 303 to move. The tooth plate 306 descends, thereby driving the peeling mechanism 4 below the tooth plate 306 to descend until the suction cup 404 is in contact with the surface of the optical film, and the air in the suction cup 404 is completely squeezed out. Then, the handle 410 is pressed downward, and the control rod 409 drives one end of all the second connecting rods 407 to press down. Under the guidance of the third connecting rod 408, the other end of the second connecting rod 407 rises accordingly, thereby driving the first connecting rod 406 and the piston 405 to rise. Since the negative pressure of the suction cup 404 is stronger after the piston 405 rises, the surface of the optical film has been sucked by the suction cup. 404 is firmly adsorbed, and the motor 302 is started again at this time, so that the motor 302 is reversed to drive the peeling mechanism 4 to rise. At this time, the surface layer of the optical film adsorbed by the suction cup 404 is gradually peeled off under the pulling force of the peeling mechanism 4. As the film is peeled off, a traction force in the horizontal direction will be generated on the sliding seat 503. Therefore, the sliding seat 503 will move horizontally in the slide groove 501 through the pulley to ensure that the film is always peeled off The position is directly below the peeling mechanism 4 until the peeling is completed; the utility model has a simple structure and a reasonable design. Through the peeling mechanism 4, the suction cup 404 can achieve rapid and effective adsorption of the functional optical film during the peeling test, improve the adsorption effect, and improve the success rate and work efficiency of subsequent peeling. The tension used in the peeling process is recorded and transmitted to the external receiving device by the tension sensor 401, which is convenient for later comparison. At the same time, by setting the sliding component 5, it is ensured that the peeled part and the unpeeled part of the optical film are always kept vertical during peeling, so that the tension data collected by the tension sensor 401 is more accurate, and the peeling efficiency and success rate of the optical film are further improved.

Those skilled in the art should understand that the utility model is not limited by the above embodiments.
