Abstract
Description
Technical Field
[0001] This utility model relates to the field of optical film printing, and in particular to a fully automatic optical film printing device with anti-offset effect. Background Technology
[0002] Conventional optical film printing equipment is mostly designed based on the characteristics of thin, flexible optical films. The fixtures usually adopt a uniformly distributed vacuum adsorption structure. The common technical bottleneck in the existing technology is the compatibility between traditional fixture systems and thick hard film materials.
[0003] Specifically, the vacuum adsorption device is prone to forming microscopic air gaps between the surface flatness tolerance of the hard film and the fixture substrate, which reduces the adsorption effect of the fixture. Furthermore, when the printing head comes into contact with the hard film, it causes the film material to shift tangentially, which restricts the yield of mass production of high-precision optical films.

[0016] The beneficial effects of the fully automatic optical film printing equipment with anti-displacement effect disclosed in this utility model are:
[0017] An external robotic arm places a tray containing an optical film onto a platform. The platform slides on the loading / unloading mechanism, bringing the tray close to the clamp. A pneumatic suction cup adsorbs the optical film. A transfer mechanism drives the pneumatic suction cup to move above the clamping area and place the optical film within it. The transfer mechanism then drives the pneumatic suction cup to move back to its original position. The output shaft of the push cylinder pushes the first and second spring-loaded components to slide on two connecting seats, causing the second limit block to move closer to the fourth limit block. The third limit block rises, making it higher than the base plate. Simultaneously, the output shaft of the limit cylinder pushes the first limit block closer to the third limit block, allowing the first, second, third, and fourth limit blocks to clamp the optical film. The printing mechanism drives the printing head to print on the optical film. After the printing head moves and prints, the printing mechanism drives the printing head to move and reset. The output shaft of the push cylinder retracts, and the first and second spring-loaded components slide and reset on the two connecting seats after losing contact with the output shaft of the push cylinder. At the same time, the output shaft of the limit cylinder pushes the first limit block away from the third limit block, causing the first, second, third, and fourth limit blocks to release the printed optical film. The output shaft of the limit cylinder pushes the first limit block to its limit position, thereby allowing the first limit block to push the optical film into the material tray, avoiding the need for a pneumatic suction cup to adsorb the printing surface of the optical film during unloading, thus avoiding leaving marks on the printing surface of the optical film. The platform slides away from the fixture on the loading and unloading mechanism, completing the automatic printing of the optical film. Attached Figure Description

[0048] Furthermore, a protrusion extends from the contact block 561, which abuts against the lever 546 of the first rebound assembly 53, and an inclined surface is provided on the contact block 561, which abuts against the lever 546 of the second rebound assembly 54.
[0049] Please refer to Figures 1-6 .
[0050] An external robotic arm places a tray 232 containing an optical film onto a platform 231. A lead screw device 23 drives the platform 231 to move, bringing the tray 232 closer to the clamp 5. After the transfer mechanism 3 places the optical film in the clamping area, the output shaft of the push cylinder 56 pushes the contact block 561 upward, causing the protrusion to contact the lever 546 of the first spring-loaded assembly 53. This causes the lever 546 of the first spring-loaded assembly 53 to rotate a certain angle on the connecting block, pushing the first spring-loaded assembly... The connecting seat 543 of 53 slides, and the second limiting block 531 moves in the through groove 512 closer to the fourth limiting block 511; the inclined surface touches the lever 546 of the second rebound assembly 54, and the lever 546 of the second rebound assembly 54 slides on the inclined surface, so that the lever 546 of the second rebound assembly 54 rotates at a certain angle on the connecting block with it, and the lever 546 pushes the connecting seat 543 of the second rebound assembly 54 to slide and rise, so that the top of the third limiting block 541 is higher than the top of the base plate 51;
[0051] The limiting cylinder 52 and the propulsion cylinder 56 operate synchronously. The output shaft of the limiting cylinder 52 pushes the first limiting block 522 to move a certain distance, so that the first limiting block 522 moves closer to the third limiting block 541, allowing the first limiting block 522, the second limiting block 531, the third limiting block 541 and the fourth limiting block 511 to clamp the optical film.
[0052] After the printing mechanism 4 completes the printing of the optical film coating, the output shaft of the push cylinder 56 pulls the contact block 561 down. After the first spring assembly 53 loses the top contact of the push cylinder 56, the spring 545 of the first spring assembly 53 pushes the slide rod 544 to pull the connecting seat 543 back to its original position, so that the second limit block 531 moves away from the fourth limit block 511. After the second spring assembly 54 loses the top contact of the push cylinder 56, the spring 545 of the second spring assembly 54 pushes the slide rod 544 to pull the connecting seat 543 back to its original position, so that the third limit block 541 descends and the top of the third limit block 541 is flush with the top of the base plate 51.
[0053] The limiting cylinder 52 and the pushing cylinder 56 operate synchronously. The output shaft of the limiting cylinder 52 pulls the first limiting block 522 to reset, so that the first limiting block 522 moves away from the third limiting block 541, allowing the first limiting block 522, the second limiting block 531, the third limiting block 541 and the fourth limiting block 511 to release the optical film. The output shaft of the limiting cylinder 52 pushes the first limiting block 522 to the limit position, so that the optical film is pushed into the material tray 232 by the first limiting block 522, avoiding the pneumatic suction cup 31 from contacting the printing surface of the optical film and leaving marks on the printing surface of the optical film when using the pneumatic suction cup 31 to unload the optical film. The lead screw device 23 drives the platform 231 to move, so that the material tray 232 moves away from the fixture 5. The external robot arm removes the material tray 232 containing the optical film, completing the automatic printing of the optical film.
[0054] This utility model provides a fully automatic optical film printing device with anti-displacement effect. An external robotic arm places a tray containing optical film on a platform. The platform slides on the loading and unloading mechanism, bringing the tray close to the clamp. A pneumatic suction cup adsorbs the optical film. A transfer mechanism drives the pneumatic suction cup to move above the clamping area and place the optical film in the clamping area. The transfer mechanism then drives the pneumatic suction cup to move and reset. The output shaft of the push cylinder pushes the first and second spring components to slide on two connecting seats, causing the second limit block to approach the fourth limit block. The third limit block rises, making it higher than the base plate. The output shaft of the limit cylinder simultaneously pushes the first limit block to approach the third limit block, allowing the first, second, third, and fourth limit blocks to clamp the optical film. After the printing mechanism drives the printing head to move above the optical film and print, the printing mechanism drives the printing head to move and reset. The output shaft of the push cylinder retracts, and the first and second spring-loaded components slide and reset on the two connecting seats respectively after losing contact with the output shaft of the push cylinder. At the same time, the output shaft of the limit cylinder pushes the first limit block away from the third limit block, so that the first, second, third, and fourth limit blocks release the printed optical film. The output shaft of the limit cylinder pushes the first limit block to the extreme position, so that the first limit block pushes the optical film into the material tray, avoiding the need for a pneumatic suction cup to adsorb the printing surface of the optical film during unloading, thus avoiding leaving marks on the printing surface of the optical film. The platform slides away from the fixture on the loading and unloading mechanism to complete the automatic printing of the optical film.
