[0002] In the process of touch screen manufacturing, optically clear adhesive (OCA) is often used to bond transparent optical elements. In the process of producing and preparing the touch screen OCA, a protective film is installed on its surface to protect its own clarity and high light transmittance. When using it, the protective film needs to be torn off and separated from the touch screen. Existing film-tearing devices usually use a sticky roller to tear off the protective film of the touch screen, but this method usually requires a 6-axis robot to collaborate to complete the film-tearing action, which is costly and occupies machine space; at the same time, the sticky roller film-tearing method is not only slow when tearing the film from the corner, but the success rate is also affected by the stickiness of the sticky roller itself, the stability is poor, and the sticky roller needs to be replaced regularly, which makes the touch screen need to spend more time and processing costs when tearing the film.

The first driving mechanism 400 is slidably connected to the mounting seat 300. The mounting seat 300 includes a rotating shaft 310. The side of the film tearing clip 200 away from the inclined portion 110 is rotatably connected to the rotating shaft 310. The film tearing clip 200 is connected to the first driving mechanism 400. When the first driving mechanism 400 slides relative to the mounting seat 300, it can drive the film tearing clip 200 to rotate relative to the axis of the rotating shaft 310. The second driving mechanism 500 is installed on the side of the mounting seat 300 away from the first driving mechanism 400. One end of the fixed seat 600 is connected to the stage 100, and the other end of the fixed seat 600 is slidably connected to the second driving mechanism 500.

One end of the first driving rod 420 is connected to the mounting seat 300, and the other end of the first driving rod 420 is connected to the first driving cylinder 410. A first mounting plate is provided on the first driving cylinder 410. The film tearing clip 200 is an "L"-shaped structure. The "L"-shaped structure of one end of the film tearing clip 200 away from the inclined portion 110 is connected to the first mounting plate, and the middle part of the film tearing clip 200 is rotatably connected to the rotating shaft 310.

A second mounting plate is provided on the second driving cylinder 510, and the mounting seat 300 is connected to the second mounting plate. When the touch screen 910 is placed on the stage 100, the protective film 920 on the touch screen 910 is firstly adsorbed through the angle vacuum hole 111 on the inclined portion 110, so that the protective film 920 can be angled relative to the touch screen 910. At this time, the second driving cylinder 510 drives the mounting seat 300 to move along the length direction of the second driving rod 520, so that the mounting seat 300, the first driving mechanism 400 and the film tearing clip 200 move closer to and away from the inclined portion 110. When they move to a suitable position, the second driving cylinder 510 drives the mounting seat 300 to move along the length direction of the second driving rod 520. The moving cylinder 510 stops moving, and the first driving cylinder 410 drives one end of the film tearing clip 200 connected to the first mounting plate to move along the length direction of the first driving rod 420, so that the film tearing clip 200 can rotate relative to the axis of the rotating shaft 310, and finally the clip end of the film tearing clip 200 presses down the protective film 920 at the corner relative to the touch screen 910, so that the protective film 920 at the corner is better separated from the touch screen 910, and finally the touch screen 910 is adsorbed and moved away to realize the film tearing operation on the touch screen 910.

[0038] Please continue reading Figure 2-Figure 6 In one embodiment, the inclined portion 110 of the film tearing device provided by one embodiment of the present invention is disposed at the top corner of the stage 100. When the film tearing clip 200 moves toward and away from the inclined portion 110, the film tearing clip 200 and the mounting seat 300 have a wider range of movement, less restrictions during the movement process, and the protective film 920 at the top corner is easier to separate from the touch screen 910, making the film tearing operation more convenient and safer.
