The technical scheme of the utility model is further described below by the specific embodiments with reference to the accompanying drawings.

The present embodiment provides a film sticking device, as shown in fig. 1 to 4, which includes a base 1 and a cover 2. The top of the base 1 is provided with a first groove 11, and the bottom of the first groove 11 is provided with a mounting seat 12 for positioning products. The bottom surface of the cover body 2 is provided with a second groove 21, the bottom of the second groove 21 is provided with a mounting table 22, and the cover body 2 is detachably covered on the base 1 to form a cavity of the second groove 21 with the base 1. An air hole 221 is provided in the mount 22 to face the mount 12, and the air hole 221 communicates with an external blowing device. The blowing device is conventional in the art and will not be described in detail here.

When the film is required to be pasted, a product is placed on the mounting seat 12, the film 100 to be pasted is placed on the top surface of the base 1, the cover body 2 is covered on the base 1 and is pressed above the film 100, a positive pressure air source is provided for the air hole 221 through the air blowing device, so that the air pressure in the cavity is increased, the film 100 is forced to deform and expand by the air pressure, and the film 100 can be attached to the product without damaging the product.

Preferably, the film laminating apparatus in this embodiment further includes a heating mechanism provided on the mounting table 22. Through setting up heating mechanism, can heat the diaphragm 100 of treating the pad pasting, can arouse the extension diffusion characteristic of diaphragm 100 like this to can make the pad pasting 100 more quick attached to the product, be favorable to improving the efficiency of pad pasting.

In some alternative embodiments, as shown in FIG. 2, mounting holes are formed in mounting table 22 and the heating mechanism includes a heating rod mounted within the mounting holes.

Of course, those skilled in the art may set the heating mechanism in other forms, and the present utility model is not limited thereto.

As shown in fig. 3, the mounting base 12 is provided with a positioning groove 121, and the product is mounted in the positioning groove 121. The positioning groove 121 can enable the product to be stably placed on the mounting seat 12, so that the product can be conveniently and quickly placed.

In particular, the bottom of the positioning groove 121 is provided with an adsorption hole (not shown), which communicates with an external vacuum device. The vacuum apparatus is conventional in the art and will not be described in detail herein. After the product is placed in the bottom of the positioning groove 121, the product seals the adsorption hole, so that the positive pressure gas in the cavity can be prevented from being extracted from the adsorption hole. By adsorbing the product through the adsorption hole, the product can be stably fixed in the positioning groove 121, which is beneficial to improving the quality of the film.

In some alternative embodiments, the product mounted in the mounting base 12 is lower than the top surface of the base 1, and the mounting base 22 protrudes from the second recess 21. Because the top surface of the base 1 is higher than the product, the membrane 100 can be conveniently lapped on the side wall of the base 1, and the membrane 100 can be conveniently attached to the product later. Meanwhile, the mounting table 22 protrudes out of the second groove 21, so that the membrane 100 can be better pressurized and heated, and the membrane 100 can be more quickly attached to a product.

In this embodiment, preferably, the outer wall of the mounting seat 12 and the side wall of the first groove 11 are arranged at intervals, so that the operation space of the operator is larger, and the product is convenient to take and place.

Optionally, the film laminating device in this embodiment further includes a sealing mechanism (not shown) disposed on one or both of two opposite sides of the base 1 and the cover 2 to seal the joint between the base 1 and the cover 2. It can be understood that by arranging the sealing mechanism, the sealing effect between the cover body 2 and the base 1 is better, so that the air pressure in the cavity can reach the preset value more quickly, and the film can be adhered more quickly.

In some alternative embodiments, the sealing mechanism comprises a sealing ring, one or both of two opposite sides of the cover 2 and the base 1 are circumferentially provided with a sealing groove, and the sealing ring is arranged in the sealing groove. When the cover body 2 is covered on the base 1, the sealing is realized between the cover body and the base through the extrusion deformation of the sealing ring. Of course, those skilled in the art may also arrange the sealing mechanism in other forms, without limitation.

The application method of the film sticking device in the embodiment comprises the following steps:

1) Placing the product in a positioning groove 121 on the mounting seat 12;

2) Tearing off the protective film of the film 100 to be attached, and placing the film 100 on the top surface of the base 1

3) The cover body 2 is covered on the protective film on the top surface of the base 1, and a cavity is formed between the cover body and the base 1;

4) Introducing positive pressure gas into the air hole 221, and simultaneously opening the heating mechanism;

5) After the membrane 100 is attached to the product, the cover body 2 is taken down, and the product and the membrane 100 are taken out;

6) And cutting off the redundant part of the membrane 100 to finish the film pasting of the product.

The technical principle of the present utility model is described above in connection with the specific embodiments.
