When the piston rod of second cylinder is flexible, first cylinder also can corresponding motion to mounting panel 41 with first cylinder connection also can corresponding motion, thereby the second cylinder can drive mounting panel 41 and be close to or keep away from the upper slitter station. When different fine carving knives are needed to perform fine carving operation on different types of mobile phone toughened films, the power mechanism 8 moves the movable mounting part 31 to enable the clamping piece 35 to be positioned at a carving station, the first driving mechanism 7 then drives the engraving part 32 to rotate so that the clamping member 35 is located at the upper tool position, then the second driving mechanism 5 drives the mounting plate 41 to lift so that the knife placing disc 43 provided with the designated fine carving knife is positioned on the same horizontal plane with the upper knife station, then the first motor 42 drives the cutter disc 43 to rotate so as to rotate the designated finishing carving knife to the same horizontal line with the upper knife station, then the third driving mechanism 6 drives the mounting plate 41 to move so that the designated finishing carving knife is positioned at the upper knife station, at this time, the holding member 35 holds the designated finishing carving knife, that is, the clamping member 35 is installed with the designated engraving knife, and then the power mechanism 8 drives the installation portion 31 to lift up, so that the clamping member 35 drives the designated engraving knife to be removed from the knife holding clamp 45.

The implementation principle of the embodiment is as follows: when different fine carving knives are needed to perform fine carving operation on different types of mobile phone toughened films, the movable mounting part 31 of the third cylinder moves to enable the clamping piece 35 to be located at a carving station, then the second motor 73 rotates to enable the worm 72 to rotate when operating, so that the worm wheel 71 meshed with the worm 72 rotates along with the worm, the rotating rod 38 also rotates along with the worm, the clamping piece 35 can conveniently rotate to an upper knife station, then the first cylinder drives the mounting plate 41 to lift so that the knife placing plate 43 provided with the appointed fine carving knife is located at the same horizontal plane as the upper knife station, then the first motor 42 drives the knife placing plate 43 to rotate so that the appointed fine carving knife rotates to be at the same horizontal line as the upper knife station, then the second cylinder drives the mounting plate 41 to move so that the appointed fine carving knife is located at the upper knife station, and at the moment, clamping jaws of the four-jaw air cylinders at the end part of the clamping piece 35 are folded to clamp the appointed fine, namely, the clamping member 35 and the designated engraving knife are installed together, then the third cylinder drives the installation part 31 to lift up so that the clamping member 35 drives the designated engraving knife to be pulled out from the knife holding clamp 45, second motor 73 is then operated to rotate engraving member 32 to rotate holder 35 to the engraving station, then the third motor drives the mounting part 31 to drive the clamping piece 35 and the graver to descend, and meanwhile, the first rotary cylinder 34 drives the clamping piece 35 and the graver to rotate so as to process the mobile phone toughened film to be processed, which is placed on the fine carving table 2, because the number of the cutter placing discs 43 is multiple, and a plurality of gravers can be placed on each cutter placing disc 43, different gravers can meet the processing requirements of different types of mobile phone toughened films, therefore, the fine engraving device for the mobile phone tempering film has the advantage of meeting the production requirement of fine engraving processing of various mobile phone tempering films.

The embodiments of the present invention are preferred embodiments of the present invention, and the scope of the present invention is not limited by these embodiments, so: all equivalent changes made according to the structure, shape and principle of the invention are covered by the protection scope of the invention.
