Description

[0002] With the rapid development of technology, touch screen technology has been widely used in various electronic devices and human-computer interaction interfaces, such as smart phones, tablet computers, and self-service terminals. Touch screens are divided into various different structures, and one of them is the OGS (One glass solution) touch screen structure. The OGS touch screen is a single-layer glass structure, which means that a touch sensing functional layer is directly formed on the protective glass. During the production process of the OGS touch screen, a second layer of ink needs to be screen-printed on the peripheral metal wiring layer of the touch screen, that is, on the basis of the border ink layer, a second layer of ink is screen-printed. The touch screen is usually divided from a large board of touch sensing glass. When screen-printing the second layer of ink, it is carried out when the touch screen is in the state of the large board of touch sensing glass. In order to avoid scratching the electrode layer on the large board of touch sensing glass during transportation, a peelable protective film is attached to the large board of touch sensing glass, and the protective film is torn off before the second layer of ink screen-printing process. However, static electricity will be generated during the film tearing process, and the static electricity will damage the electrode layer, resulting in the failure of the touch screen performance.

[0021] In order to facilitate the understanding of the present utility model, the present utility model will be described more comprehensively below with reference to the relevant drawings.

[0022] Please refer to Figure 1 and Figure 2As shown in the figure, an anti-static film tearing device 10 for a touch screen includes a positioning base 100, a film tearing assembly 200, and an anti-static module 300. A positioning groove is formed on the positioning base 100, and the positioning groove is used for limiting the large-panel touch sensing glass 20. The film tearing assembly 200 includes a moving frame 210 and a film tearing manipulator 220. The moving frame 210 is movably arranged on the positioning base 100, and the film tearing manipulator 220 is arranged on the moving frame 210. The film tearing manipulator 220 is used to grab the protective film on the large-panel touch sensing glass 20, and the moving frame 210 is used to drive the film tearing manipulator 220 to move from one side of the large-panel touch sensing glass 20 to the other side of the large-panel touch sensing glass 20, so that the protective film is peeled off from the large-panel touch sensing glass 20. The anti-static module 300 is arranged on the moving frame 210, and the moving frame 210 is also used to drive the anti-static module 300 to move from one side of the large-panel touch sensing glass 20 to the other side of the large-panel touch sensing glass 20.

[0023] It should be noted that when using the anti-static film tearing device, first place the large-panel touch sensing glass 20 on the positioning groove of the positioning base 100, and perform a positioning operation on the large-panel touch sensing glass 20 through the positioning groove to avoid position deviation. Then, grab a corner of the protective film on the large-panel touch sensing glass 20 through the film tearing manipulator 220 to fix the protective film. Finally, drive the film tearing manipulator 220 from one side of the large-panel touch sensing glass 20 to the other side of the large-panel touch sensing glass 20 through the moving frame 210. In this way, the protective film can be separated from the large-panel touch sensing glass 20. In addition, by arranging the anti-static module 300 on the moving frame 210, the anti-static module 300 can follow the movement during the film tearing process, and then the static electricity generated during the film tearing process can be eliminated in time through the anti-static module 300, thereby avoiding static electricity from damaging the electrode layer. In this embodiment, the anti-static module 300 is an existing anti-static device, such as an electrostatic eliminator bar.

[0024] In one embodiment, in order to further fix the large-panel touch sensing glass 20 and further avoid the large-panel touch sensing glass 20 from shifting in position due to excessive film tearing force during the film tearing process, vacuum adsorption holes 110 are formed at the bottom of the positioning groove. The vacuum adsorption holes 110 are used for adsorbing and positioning the large-panel touch sensing glass 20. Specifically, the positioning base 100 is connected to a corresponding suction device, so as to realize the adsorption and fixation of the large-panel touch sensing glass 20 through the vacuum adsorption holes 110. Preferably, the vacuum adsorption holes 110 are distributed in a rectangular array.

[0025] In one embodiment, a sliding guide groove 120 is formed in the positioning base 100, and a sliding block is provided on the moving frame 210. The sliding block is slidably disposed in the sliding guide groove 120. In this way, the stability of the moving frame 210 during movement can be ensured. In this embodiment, two sliding guide grooves 120 are formed. Correspondingly, two sliding blocks are provided on the moving frame 210. In this embodiment, a displacement driving member is connected to the moving frame 210. Through the displacement driving member, the automatic film tearing operation of the large panel touch sensing glass 20 is realized, thereby reducing the participation of manual labor and improving the efficiency. Preferably, the displacement driving member is a driving cylinder. In another embodiment, the displacement driving member can also adopt a linear motor module or a servo motor lead screw driving structure.

[0026] In one embodiment, the film tearing manipulator 220 includes a lifting driving member 221 and a film tearing fixing member 222. The lifting driving member 221 is disposed on the moving frame 210, and the lifting driving member 221 is connected to the film tearing fixing member 222.

The lifting driving member 221 is used for driving the film tearing fixing member 222 to perform reciprocating displacement in a direction close to or away from the large panel touch sensing glass 20. During the film tearing process, first, the lifting driving member 221 drives the film tearing fixing member 222 to move in a direction close to the large panel touch sensing glass 20 until the film tearing fixing member 222 contacts the protective film. Then, one corner of the protective film can be fixed by the film tearing fixing member 222. After the fixing is completed, the driving end of the lifting driving member 221 retracts so that one corner of the protective film is separated from the large panel touch sensing glass 20. Finally, the protective film is torn off from the large panel touch sensing glass 20 by the moving frame 210. At the same time, during the film tearing process, the anti-static module 300 moves along, so that the static electricity generated during the film tearing process can be eliminated in time, avoiding static electricity from damaging the electrode layer. Preferably, the lifting driving member 221 is a lifting cylinder.

[0027] Further, the film tearing fixing member 222 includes a connecting rod and a fixing block. The driving end of the lifting driving member 221 is connected to one end of the connecting rod, and the fixing block is disposed at the other end of the connecting rod. And an adhesive layer is provided on a side surface of the fixing block facing the large panel touch sensing glass 20. The adhesive layer is a solid adhesive, and the protective film is adhered by the adhesive layer, so as to play a role in fixing the protective film during the film tearing process.

[0028] In one embodiment, in order to improve the degree of automation of the film tearing of the anti-static film tearing device, the film tearing assembly 200 further includes a sensor, which is arranged on the moving frame 210. When the large panel touch sensing glass 20 is placed in the positioning groove, it is recognized by the sensor, and the signal is transmitted to the control terminal, and the film tearing assembly 200 and the anti-static module 300 are controlled to start through the control terminal. In this way, manual participation can be reduced and the film tearing efficiency can be improved.
