In this embodiment, as shown in FIG. 4 , the pressing shell member 62 includes a pressing plate 64 and a connecting plate 63 connecting the pressing plate 64 and the slide bar 66. The side of the connecting plate 63 far away from the mounting plate 11 is provided with a slot, and the pressing plate 64 is locked. into the card slot.

In this embodiment, the slide bar 66 and the stopper 69 are separate components, and the slide bar 66 and the stopper 69 are connected by screws. Of course, in this solution, the connection method between the slide bar 66 and the stopper 69 is not limited thereto. In other embodiments, the slide bar and the stopper are separate components, and the stopper block is connected to the slide bar through a snap-fit structure, or, In other embodiments, the sliding rod and the stopper are integral components.

The working principle of the above automatic film laminating machine is as follows:

First start the cylinder 20, the cylinder 20 acts on the lower lifting plate 30, and the pressing shell 62 moves downward under the promotion of the lower lifting plate 30, each push rod 68, the upper lifting plate 61 and each slide bar assembly 65, and the hemming mechanism 40 then Under the promotion of the lower lifting plate 30, it also moves downward; then, the pressing plate 64 of the shell pressing member 62 is pressed on the mobile phone case first, and the edge wrapping mechanism 40 continues downward under the action of the upper lifting plate 61 overcoming the resistance of the elastic member 67 Movement, in this process, the pressure that pressing plate 64 is pressed on the mobile phone shell gradually increases in the process that spring is compressed, makes mobile phone shell not easy to move; The four sides of the shell are in contact, and the four concave rollers 51 of the wrapping mechanism 40 are in contact with the four end corners of the mobile phone case respectively, and the wrapping mechanism 40 continues to move downward, so that the four sides of the diaphragm They are respectively gradually pressed on the four sides of the mobile phone case, and at the same time, the four end corners of the diaphragm are also gradually pressed on the four end corners of the mobile phone end; when the sides and ends of the mobile phone case After the corner is covered by the diaphragm, the cylinder 20 drives the lower lifting plate 30 to move upwards, and the wrapping mechanism 40 moves upwards under the pull of the lower lifting plate 30, and the four edge-holding components 47 of the wrapping mechanism 40 are respectively on the mobile phone case. The edges of the four pasted films are re-extruded, and the four concave rollers 51 are also respectively re-extruded to the four end corners of the mobile phone case, so that the diaphragm is more firmly bonded to the edges of the mobile case. Finally, under the pulling of the lower lifting plate 30, the hemming mechanism 40 first breaks away from the mobile phone case and returns to its original position, while the shell pressing member 62 is on each push rod 68 of the lower lifting plate 30, the upper lifting plate 61 and each slide bar assembly 65 pulls and then breaks away from the phone case and returns to its original position.

The invention realizes that the four sides of the mobile phone case can be automatically film-wrapped at the same time, without manual labor, and the work efficiency is improved; the setting of the pressing part 62 makes the mobile phone case be pressed during the process of wrapping, avoiding The mobile phone case moves during the wrapping process, which affects the effect of the film wetting, and improves the lamination accuracy of the film.

The above-mentioned embodiments only express several implementation modes of the present invention, and the descriptions thereof are relatively specific and detailed, but should not be construed as limiting the patent scope of the invention. It should be noted that those skilled in the art can make several modifications and improvements without departing from the concept of the present invention, and these all belong to the protection scope of the present invention. Therefore, the protection scope of the patent for the present invention should be based on the appended claims.
