Film sticking machine capable of automatically tearing off release paper

Abstract

The invention discloses a film sticking machine capable of automatically tearing off release paper. According to the film sticking machine, an absorbing device is used for adsorbing an adhesive film and feeding the adhesive film to a platform; the adhesive film is adsorbed and positioned on the platform through the suction hole on the platform; a pusher is used for upwards pushing and supporting a push piece and pushing and supporting an end corner of the release paper stuck above the adhesive film to tilt; and a clamping jaw of a clamping device is used for clamping the tilt part of the end corner to move along a track at a certain horizontal height and tearing off the release paper in a diagonal direction, thereby subsequent film sticking operation can be carried out. Therefore, one end corner of the release paper is lifted by a corner lifting device and a mode of tearing off the release paper by using the clamping jaw at a certain horizontal equal height is used, thereby the surface of the adhesive film is prevented from being touched and the condition that the adhesive film is crinkled is avoided.

Description

technical field [0001] The invention relates to a film sticking machine capable of automatically tearing off the release paper, in particular to an automatic film sticking machine which can automatically tear off the release paper from the film when pasting the film on a touch panel substrate. Background technique [0002] The touch panel substrate is mainly used in the information display of electronic products. The information displayed on the touch panel substrate can provide users with direct selection with their fingers or stylus. Therefore, for electronic product manufacturers, how to Pasting a protective film on the surface of the touch panel substrate is an important issue. [0003] Generally, before sticking the adhesive film, the release paper on the surface of the adhesive film needs to be torn off before the adhesive film can be pasted; and the existing automatic tear-off paper machine, please refer to the first picture , it is to be provided with a platform 10,...

Problems solved by technology

[0003] Generally, before sticking the adhesive film, the release paper on the surface of the adhesive film needs to be torn off before the adhesive film can be pasted; and the existing automatic tear-off paper machine, please refer to the first picture , it is to be provided with a platform 10, and the platform 10 is provided with a plurality of suction holes 11 arranged in an array, thus an adhesive film 12 is adsorbed on the platform 10, and the platform 10 is on the upper surface of the adhesive film 12. Above the release paper 13, a roller 14 is provided, and the roller 14 rolls an adhesive tape 15 so that the adhesive tape 15 contacts the surface of the release paper 13, and the adhesive tape 15 is utilized to tear off the release paper 13; Although the existing automatic tear-off paper machine can use the stickiness of the adhesive tape 15 to tear off the release paper 13, the method of tearing off the release paper 13 with the adhesive tape 15 requires a rather long adhesive tape 15 to roll and contact the release paper. The surface of the molded paper 13 causes a considerable consumption of adhesive tape 15 (consumables), which increases the cost, and the adhesive tape 15 is limited. After three or four times of use, it may not be sticky, and the release paper 13 cannot be torn off. lead to poor reliability

[0004] In addition, there is also an existing automatic tear-off type paper machine, as shown in Figure 2, which is provided with a platform 10, and a plurality of suction holes 11 arranged in an array are arranged in the platform 10, so that a Adhesive film 12 is adsorbed on the platform 10, and the platform 10 is provided with a suction device 20 above a release paper 13 on the upper surface of the adhesive film 12. The suction device 20 contacts the surface of the release paper 13 and utilizes negative pressure Suction, this release paper 13 is torn off; Like this, this another kind of existing automatic tear-off paper machine, though can utilize negative pressure suction to tear off release paper 13, but this suction device 20 is in this adhesive film 12 When the release paper 13 is torn off by negative pressure suction above, the negative pressure suction of the suction hole 11 of the platform 10 will be insufficient, and the platform 10 needs to absorb the adhesive film 12 with a greater suction force before the release paper can be torn off. 13, and the large negative pressure suction will easily make the film 12 wrinkle, resulting in very ugly bubbles after the film is pasted

Therefore, this existing automatic tear-off type paper machine still has deficiencies, thereby there is a need for improvement
