The utility model also provides a display screen attaching device, which comprises an upper cavity with an opening at the lower end, a lower cavity with an opening at the upper end and a vacuum pump communicated with the upper cavity or the lower cavity through an exhaust pipe, wherein an upper cavity jig is arranged in the upper cavity, a mounting groove for mounting and attaching curved glass is arranged on the lower end surface of the upper cavity jig, a profiling elastic piece 50 is arranged at the bottom of the lower cavity, the upper surface of the profiling elastic piece 50 is a tile-shaped arc surface facing the mounting groove, the display screen attaching device is arranged in the lower cavity through a first lifting device, a second lifting device for driving the lower cavity to move towards the upper cavity so as to enable the upper cavity to be connected with the lower cavity in a sealing manner is further arranged on the lower cavity, and a third lifting device 51 for driving the profiling elastic piece to lift is connected on the profiling elastic piece, so that the screen body is tightly pressed and attached to the curved glass by the profiling elastic piece.

Be equipped with the epicoele tool in the epicoele body, the lower terminal surface of epicoele tool is equipped with the resettlement groove that is used for installing curved surface glass, and the resettlement groove has the same curved surface with curved surface glass, and when guaranteeing that curved surface glass installs in the resettlement groove, curved surface glass can laminate with the resettlement groove completely. The bottom of cavity is equipped with profile modeling elastic component 50 down, and this profile modeling elastic component 50 can be silica gel or rubber etc. have elastic material, and the upper surface of profile modeling silica gel spare is the tile type cambered surface, and this tile type cambered surface just to the resettlement groove of epicoele tool to compress tightly the laminating of flexible panel on the curved surface glass of resettlement inslot through profile modeling elastic component. The display screen laminating device for clamping the bearing film is positioned in the lower cavity, the bearing film is an elastic film, and a flexible panel is adhered to the upper surface of the bearing film.

Go up the cavity or be connected with the vacuum pump through the blast pipe on the cavity down, when last cavity and cavity lock down formed airtight cavity, the accessible vacuum pump was taken out the air in the airtight cavity to carry out subsequent laminating.

The equipment further comprises a vision system used for acquiring the position information of the screen body on the carrier film and an alignment system connected to the vision system, wherein the alignment system is connected to the driving part and used for controlling the motion platform 20 to move along the first direction and/or the second direction according to the position information so as to enable the flexible panel on the carrier film to face the placement groove.

When the display screen laminating equipment is used for laminating the flexible panel and the curved glass, the back surface of the flexible panel is attached to the bearing film and is conveyed to the middle device of the upper cavity and the lower cavity, the second lifting device is driven to the lower cavity to move towards the upper cavity, so that the upper cavity and the lower cavity are connected in a sealing mode, and meanwhile, the first lifting device drives the display screen laminating device to move synchronously. The motion platform 20 is in the initial position, and the edge of the first clamp 21 is equidistant from the curved edge of the contoured elastic member 50. The first clamp 21 moves to an edge position of the carrier film along a first direction and clamps opposite sides of the carrier film. The vision system obtains the position information of the flexible panel relative to the arrangement groove and transmits the obtained position information to the alignment system, and the alignment system drives the moving platform 20 to move through the driving part according to the position information so that the flexible panel is opposite to the arrangement groove, and the flexible panel is aligned with the curved glass.

Because the distance between the edge of the first clamp 21 on both sides and the curved surface edge of the profiling elastic piece 50 is unequal, if the profiling elastic piece presses the flexible panel and the curved glass for fitting, the moving distance of the carrier films on both sides can be unequal, and the flexible panel and the curved glass are inconsistent in contact in the bending area during fitting, which easily causes uneven bubbles in the bending areas on both sides and causes the problem of poor fitting bubbles.

According to the utility model, after the first clamp 21 clamps the carrier film for alignment, the second clamp 11 moves to the edge position of the carrier film along the second direction and clamps the other two opposite sides of the carrier film, so that the position of the carrier film is kept still, the first clamp 21 releases the carrier film, the driving part drives the motion platform 20 to move to the initial position, and the first clamp 21 clamps the two opposite sides of the carrier film again. The third lifting device 51 drives the profiling elastic element 50 to move upwards to completely press and attach the flexible panel to the curved glass, and particularly, at the bending part of the curved glass, under the deformation and extrusion of the profiling elastic element 50, the attaching effect of the flexible panel and the curved glass can be ensured. Meanwhile, the first clamp 21 and the second clamp 11 synchronously move towards the center, and because the distances between the edges of the first clamp 21 on the two sides at the moment and the curved surface edge of the profiling elastic piece 50 are equal, the flexible panel is in consistent contact with the bending areas on the two sides of the curved glass during the laminating process, the stability of the bearing film in the profiling process is improved, and the problems of laminating deviation and laminating bubble generation are reduced. This equipment keeps the position of the carrier film after counterpointing through second anchor clamps 11 for the centre gripping carrier film once more after first anchor clamps 21 return, so that when flexible panel and curved surface glass laminate, the edge of first anchor clamps 21 equals with curved surface glass's distance, thereby improves the yields of laminating.
