The existing waterproof film attaching method is generally to peel the waterproof film from the release bottom film manually and then to attach the waterproof film to the metal threaded hole. This approach has the following drawbacks: firstly, the film sticking efficiency is low; secondly, the waterproof membrane is easily damaged during manual stripping; thirdly, when the waterproof film is pasted, the positions of the middle holes and the metal threaded holes are required to be completely corresponding, and the yield of the manual pasting mode is low.

The patent with the application number of 201720528552.9 discloses a waterproof film sticking mechanism, and the technical scheme introduced is that a release film is peeled off first, and then the waterproof film is transferred and stuck to a product from a bottom film in a roller rolling mode. Firstly, the patent aims at sticking a waterproof film on a completely flat surface material such as glass, and cannot be realized if the product is a product with a concave-convex structure on the surface; secondly through the in-process of rolling the waterproof membrane from the basement membrane to pasting the glass plane materiel, can't guarantee that every waterproof membrane can both accomplish smoothly and change and paste, and some waterproof membranes still paste on the basement membrane and lead to the pad pasting failure probably.

Patent application No. 202110133304.5 discloses a stripping device of coil stock sponge and an automatic device for applying the stripping device to an in-shell film, and the introduced technical scheme is as follows: the material area is exported from the blowing roller, and under the drive that draws the material subassembly, the material area through the material track back, the integument on the material area is peeled off to shelling the material platform on, and final waste material area is rolled up to receiving in the material roller. Firstly, directly peel off the membrane body to peeling off the material platform from the material area in this scheme, if the membrane body itself has viscidity or the material of membrane body is softer, then difficult realization, the membrane body probably does not peel off automatically and is rolled up along with the waste material area together, or takes place the condition of overstock pile at peeling off the front end of material platform, leads to the membrane body to damage or warp, unable normal use. Secondly, the sponge is peeled off in the scheme, if the surface of the sponge is provided with a sticky waterproof film, after the front end of the film body moves to the stripping platform, the friction force between the film body and the stripping platform is increased due to the self viscosity, so that the film body cannot move to the stripping platform integrally, and normal feeding is influenced.
