Understandably, the two sides of the film sticking equipment 1 can be stuck with films, and the selectivity is high; the models of the electronic devices 3 matched with the positioning grooves 11 on the two sides of the shell 10 can be the same or different; when the models of the electronic devices 3 matched with the positioning grooves 11 on the two sides of the shell 10 are the same, the cost performance is higher; when the models of the electronic devices 3 matched with the positioning grooves 11 on the two sides of the shell 10 are different, the universality is stronger.

Referring to fig. 1, fig. 2 and fig. 4, further, since the size of the protective film 21 itself is smaller than that of the electronic device 3, a clamping groove 1111 is formed at the bottom 111 of the positioning groove 11, and the clamping groove 1111 is used for clamping the protective film 21. It can be understood that the catching groove 1111 is a recessed groove formed by recessing a portion of the groove bottom 111 of the positioning groove 11. At the pad pasting in-process, arrange protection film 21 in the joint groove 1111 department of constant head tank 11 earlier, joint groove 1111 joint protection film 21, put into constant head tank 11 with electronic equipment 3 after that and the screen is close to the mode of protection film 21 is put into, upset pad pasting equipment 1 again for 3 backs of electronic equipment and desktop contact, through setting up joint groove 1111, when upset pad pasting equipment 1, protection film 21 is blocked in the joint groove 1111, can not take place to laminate because of the screen of dead weight slippage directness and electronic equipment 3, make the bubble of being difficult to the combustion gas appear between protection film 21 and the screen. In addition, the clamping groove 1111 limits the protective film 21 to a certain extent, and the problem that the position of the film 213 is inaccurate due to movement in the film sticking process is solved.

Referring to fig. 1, 4 and 5, the area S2 of the bottom of the locking groove is smaller than the area S1 of the bottom of the positioning groove. Can understand ground, the tank bottom area S2 in joint groove is corresponding with the area of protection film 21, and the tank bottom area S1 that the tank bottom area S2 in joint groove is less than the constant head tank has avoided at the pad pasting in-process, and electronic equipment 3 can't spacing to the constant head tank 11 in, and removes or the slippage to the joint groove 1111 in the constant head tank 11 to cause the not accurate problem of pad pasting position, pad pasting effect is poor.

Referring to fig. 1 and fig. 6, a hand-held recess 1122 is further formed on the groove wall 112 of the positioning groove 11. It can be understood that the number of the handheld recessed portions 1122 is at least one, and preferably, the number of the handheld recessed portions 1122 is two and is correspondingly disposed on two opposite sides of the first side wall 1123 or the second side wall 1124, and the handheld recessed portions 1122 can be used by a person to hold the film sticking apparatus 1 with one hand and put the protective film 21 into the other hand or take out the protective film 21, so that the film sticking operation is more convenient.

Referring to fig. 1 and fig. 7, further, the bottom 111 of the positioning slot 11 is provided with a through hole 1112 penetrating through the bottom 111. Preferably, the through hole 1112 extends along the thickness direction of the groove bottom 111, and when the groove bottom 111 is fastened on the electronic device 3, the through hole 1112 structure can be used for a hand to insert and remove to perform a bubble scraping operation, so that the operation is more convenient.

Further, with reference to fig. 1 and fig. 7, the release film 215 includes a release film 2151, a first film 2152 and a second film 2153 extending along the length or width direction of the release film 2151, the release film 2151 is sandwiched between the dustproof film 211 and the film 213, the first film 2152 is disposed at one end of the release film 2151, and the second film 2153 is stacked on the first film 2152 and connected to the main film 2110 of the dustproof film 211.

Specifically, the second film 2153 and the dust-proof film 211 are connected by adhesion, the dust-proof film 211 is used for protecting the release film 215 and the film 213 which are not attached, and in the attaching process, after the user places the protection film 21 into the positioning groove 11, the film attaching device 1 is then covered on the electronic device 3 together with the protection film 21. Then, a pulling force is applied to the first protrusion 2111, so that the dust-proof film 211 is pulled out from the passage 1121. After the dust-proof film 211 is pulled off, the pulling force further acts on the release film 2151 through the second film 2153 and the first film 2152 until the release film 2151 is pulled off from the channel 1121, that is, when the release film 215 is removed, one end of the release film 215 far away from the channel 1121 is removed first, and then one end of the release film 215 close to the channel 1121 is removed. When the release film 215 is removed, the release film 2151 is pulled to bend towards the screen of the electronic device 3, so that the bent release film 2151 contacts with the screen of the electronic device 3, and dust on the surface of the screen is adsorbed by electrostatic action when the release film 2151 is pulled down, that is, the dust is removed together with the release film 2151 pulled out of the channel 1121. Wherein before the pad pasting operation, the existence of dust-proof membrane 211 can protect from type membrane 215, prevents to adsorb other dusts in the air from type membrane 215, has avoided taking place the loss from type membrane 215's dust removal ability before tearing the desorption. Then, the user applies a pressure to the side of the housing 10 away from the screen of the electronic device 3 to perform the film pasting on the electronic device 3. Preferably, after the dustproof film 211 and the release film 215 are removed, one end of the membrane 213 away from the stopper 12 will contact the screen of the electronic device 3 first, so that the point of pressure application is preferentially applied to the contact position of the membrane 213 and the screen of the electronic device 3. Then, the pressure gradually moves towards one side of the limiting part 12, the membrane 213 is attached to the surface of the screen of the electronic device 3 after being stressed, and along with the gradual reduction of the included angle a between the electronic device 3 and the protective film 21, bubbles are gradually discharged, the film attaching efficiency is high, and the film attaching effect is good. After the film is pasted, the film pasting equipment 1 is taken down, the positioning film 212 is torn down, the film 213 is exposed, and all film pasting operations can be completed, so that the film pasting equipment is simple and convenient to use.
