Cutting and attaching system for screen protector having high hardness

A cutting and attaching system for a screen protector having a high hardness, comprising:

• a cutting apparatus including:
• a carrying machine;
• a displacement mechanism being assembled to the carrying machine and being movable relative to the carrying machine;
• a processing module assembled to the carrying machine, wherein the processing module is electrically coupled to the displacement mechanism and is configured to move the displacement mechanism along a first cutting path and a second cutting path that is different from the first cutting path, and wherein the second cutting path corresponds to a contour of a screen of a mobile apparatus;
• and
• a cutter assembled to the displacement mechanism and having a cutting segment exposed from the displacement mechanism, wherein the displacement mechanism is configured to move the cutting segment between an upper position and a lower position that is lower than the upper position;
• and
• a universal sheet that is configured to be cut to form the screen protector through a cutting process of the cutting apparatus, wherein the universal sheet includes:
• a usage layer including a hardened film and a bonding film that is formed on the hardened film, wherein a hardness of the hardened film is at least 5H;
• a buffer layer having a hardness that is less than the hardness of the hardened film;
• a release layer attached onto the bonding film;
• and
• a bottom layer attached onto the release layer;
• wherein, when the universal sheet is placed on the cutting apparatus under the cutting process, the bottom layer of the universal sheet is fixed to the carrying machine, the displacement mechanism is driven by the processing module to enable the cutting segment of the cutter at the upper position to cut the buffer layer and the usage layer along the first cutting path for forming a positioning contour, and along the second cutting path for forming a screen contour, such that the buffer layer and the usage layer jointly define a screen region and a positioning region that is arranged at one side of the screen region and that has a plurality of positioning holes and an arrangement tab;
• and
• a film applicator located at a downstream of the cutting apparatus and including:
• an accommodating chamber configured to hold the mobile apparatus;
• and
• a plurality of positioning pillars having a relative position that is identical to a relative position of the positioning holes of the positioning contour, wherein a relative position between the positioning pillars and the screen of the mobile apparatus is identical to a relative position between the positioning holes and the screen contour;
• wherein, when the accommodating chamber of the film applicator holds the mobile apparatus, a pull strip of the cutting and attaching system is adhered to a portion of the release layer corresponding in position to the arrangement tab and is folded to be stacked on the release layer, and the positioning holes of the positioning region are respectively sleeved at the positioning pillars to place the pull strip between the release layer and the screen of the mobile apparatus, so that the pull strip is configured to be pulled out of the accommodating chamber to remove the release layer from the bonding film for enabling the release layer to remove particles on the screen through electrostatic adsorption.
