Detailed implementation manner

[0017] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0018] Please refer to Figures 1-5, a film pasting device for a tablet computer, including a frame body 1. At the top of the frame body 1, there are a first square-round positioning post 5 and a second square-round positioning post 6. On both sides of the cavity of the frame body 1, there are respectively fixedly installed first connecting bars 2. At the other end of the first connecting bars 2, there is fixedly installed a load-bearing ring block 3. On the outer arc surface of the load-bearing ring block 3, there is fixedly connected a second connecting bar 4. On the other side of the second connecting bar 4, there is fixedly connected to the frame body 1. On both sides of the frame body 1, there are respectively opened limiting inclined grooves 7. Inside the limiting inclined grooves 7, there is a sliding sleeve 8. Inside the sliding sleeve 8, there is movably connected an insertion rod 9. On the side surface of the insertion rod 9, there is fixedly installed a fixed sleeve 10. Inside the fixed sleeve 10, there is a fixed block 13 in fit. The fixed block 13 is provided with a connecting groove 14. Inside the connecting groove 14, there is fixedly installed a fixed shaft 15. On the surface of the fixed shaft 15, there is movably installed an auxiliary rolling bubble scraping sleeve ring 16. The auxiliary rolling bubble scraping sleeve ring 16 contacts the tempered film 18. Then, control the auxiliary rolling bubble scraping sleeve ring 16 to rotate on the surface of the fixed shaft 15 and the insertion rod 9 to control the sliding sleeve 8 to slide inside the limiting inclined groove 7. Thus, the auxiliary rolling bubble scraping sleeve ring 16 scrapes from the head to the bottom, extruding the bubbles out, achieving the effect of precise film pasting and adsorbing and taking out dust spots. The number of both the first square-round positioning post 5 and the second square-round positioning post 6 is two. The two first square-round positioning posts 5 are symmetrically distributed. The two second square-round positioning posts 6 are symmetrically distributed. At the bottom end inside the fixed sleeve 10, there are fixedly installed a damping rod 11 and a spring 12. The top of the damping rod 11 and the spring 12 are fixedly connected to the fixed block 13. On the surface of both the two first square-round positioning posts 5, there is a first snap-on film 17 in fit. On the side surface of the first snap-on film 17, there is fixedly installed a tempered film 18. By placing the tablet computer in the middle limiting cavity with the camera facing downwards in the bottom hollow area, and then placing the tempered film 18 above, and aligning the hole positions of the first snap-on film 17 and the second snap-on film 19 on both sides of the tempered film 18 with the two first square-round positioning posts 5 and the two second square-round positioning posts 6 and sleeving them on. After pulling the pull-out film below the film, after the pull-out strip pulls out the auxiliary device, the overall scheme of this solution is light, small in volume, simple to operate, can remove dust, has regular exhaust, and is placed flat on the front. The camera is placed in the bottom hollow area, without unevenness. It can not only paste glass films but also paste writing paper films for learning. On the other side of the tempered film 18, there are fixedly installed two second snap-on films 19. Inside both the two second snap-on films 19, there is a second square-round positioning post 6 in fit. There is an inclined slot opening 20 on the side surface of the frame body 1. When pulling the tempered film 18 or a similar film, static electricity is generated when the bottom silica gel layer separates from the bottom protective layer PET. The static electricity has the function of adsorbing dust spots. The static electricity will adsorb the dust spots on the film and the touch display area of the tablet. As the pull-out strip is pulled out, the static electricity adsorption will also adsorb and take out the dust spots. When the pulling is completed, since the film is suspended above the electronic device at an inclined angle, the auxiliary rolling bubble scraping sleeve ring 16 rotates on the surface of the fixed shaft 15 and the insertion rod 9 controls the sliding sleeve 8 to slide inside the limiting inclined groove 7.Furthermore, it causes the auxiliary rolling bubble scraping collar 16 to scrape from the head to the bottom, squeezing out the bubbles. The operation is simple and easy to understand, the appearance is light, the transportation cost is low, the stability is high, the film pasting is accurate, and it also has the effect of adsorbing and taking out dust points. It can not only paste glass films, but also paste writing paper films.

[0019] Working principle: During the operation, the operator places the tablet computer inside the middle limiting cavity with the camera facing downwards in the bottom empty area. Then, the tempered glass film 18 is placed on top, and the holes of the first snap-on film piece 17 and the second snap-on film piece 19 on both sides of the tempered glass film 18 are aligned with the two first square-round positioning posts 5 and the two second square-round positioning posts 6 and sleeved on. After pulling the pull tab under the film piece and pulling out the auxiliary device with the pull bar, the operator then uses the fixed sleeve 10 to control the rotation of the insertion rod 9 inside the sliding sleeve 8. At the same time, the fixed block 13 on the side of the fixed sleeve 10 drives the auxiliary rolling bubble scraping collar 16 on the surface of the fixed shaft 15 inside the connecting groove 14 to flip. During the flipping process, the auxiliary rolling bubble scraping collar 16 contacts the tempered glass film 18. Then, control the auxiliary rolling bubble scraping collar 16 to rotate on the surface of the fixed shaft 15 and the insertion rod 9 to control the sliding of the sliding sleeve 8 inside the limiting inclined groove 7. Furthermore, it causes the auxiliary rolling bubble scraping collar 16 to scrape from the head to the bottom, squeezing out the bubbles, achieving the effects of accurate film pasting and adsorbing and taking out dust points.
