Description

Film sticking device

Technical Field

The utility model relates to the technical field of film sticking devices, in particular to a film sticking device.

Background

In the existing electronic products with screens such as mobile phones and computers in the market, a layer of protective film is generally attached to the surface of the screen to protect the screen, and the protective film is damaged after a period of use because the screen is often touched, so that the protective film needs to be replaced frequently. The roller type film sticking device is a novel film sticking device, the film sticking product and the protective film are positioned through the positioning structure, and the roller is arranged to roll the protective film, so that the protective film can be sequentially stuck to a screen of the film sticking product from one end to the other end of the protective film, and the protective film can be accurately and efficiently stuck to the film sticking product.

However, when the roller type film sticking device is used for sticking films, film sticking bubbles are easily generated at the tail end of a screen of a product to be stuck with the films, and the main reason is that:

As shown in fig. 1, the conventional roller type film sticking device generally comprises a base 1 and a rolling assembly, wherein the rolling assembly comprises a roller 22, positioning columns 10 are arranged at two ends of the base 1, and a protective film 3 comprises an upper protective film 31 (i.e. a positioning film), a protective film body 32, a lower protective film (not shown) and a drawing bar (not shown) which are sequentially stacked from top to bottom. When the film is pasted, a product 5 to be pasted is placed in a base 1, two ends of an upper protective film 31 are respectively hung on positioning columns 10 at two ends of the base 1, the protective film 3 is hung above the product 5 to be pasted, a certain distance is reserved between the lower surface of the protective film 3 and the product 5 to be pasted (i.e. the lower surface of the protective film is not contacted with the product 5 to be pasted), then the lower protective film is torn off from a protective film body 32 by pulling a pull strip, namely, the state shown in fig. 1 is achieved, and then a driving roller 22 moves from one end to the other end of the product 5 to be pasted. The roller 22 rolls the upper protective film 31 and the protective film body 32 in the moving process, so that the protective film body 32 is sequentially attached to the screen of the product 5 to be coated, and the protective film body 32 is gradually separated from the upper protective film 31.

When the roller 22 gradually moves to the end of the product 5 to be laminated, since most of the positions of the protective film body 32 are separated from the upper protective film 31 at this time, that is, the adhesive area between the protective film body 32 and the upper protective film 31 at this time is small, the connecting force between the two is weak, so that when the roller 22 has not been rolled to the end of the product 5 to be laminated, the end of the protective film body 32 has fallen to the surface of the product 5 to be laminated under the action of its own weight, and bubbles are easily formed between the end of the protective film body 32 and the product 5 to be laminated (even after the subsequent rolling by the roller 22, the bubbles still cannot be effectively eliminated), thereby generating film-laminated bubbles at the screen end of the product 5 to be laminated (especially when the protective film body 32 is a curved film).

In view of the above, it is necessary to design a film sticking apparatus capable of avoiding the generation of film sticking bubbles.
