Embodiment
For the technology contents that the present invention will be described in detail, the objects and the effects, below in conjunction with embodiment and coordinate attached
Figure is explained.
The design of most critical of the present invention is:Adhesive film is rotated before fitting, makes adhesive film and curved-surface display to be fit
Screen 3 is a certain included angle, and the initial position using the phase tangent line on right side as pressing, and court moves left pressing since initial position
Device 1, realizes the fitting of mid-plane and left side curved edge, then returns initial position court and moves right pressing device 1
Complete the fitting of right side curved edge.
It refer to Fig. 1 to Fig. 4, a kind of method for adhering film of camber display screen, including step：
S1, rotation adhesive film, make the second side of adhesive film be inclined upwardly relative to first side, the first side,
The first curved edge with camber display screen 3, the second curved edge are corresponding respectively for second side；
S2, using pressing device 1 push the adhesive film, adhesive film is in contact first with the first tangent line, and described first
Tangent line is the first curved edge and the phase tangent line of mid-plane on camber display screen 3；
S3, pressing device 1 persistently compress the adhesive film and are moved to close to the direction of the second curved edge, by adhesive film
It is pressed together in mid-plane, until reaching at the second tangent line；Second tangent line for the second curved edge on camber display screen 3 with
The phase tangent line of mid-plane；
S4, pressing device 1 continue to compress the adhesive film and are moved along the outer surface of the second curved edge, by adhesive film
Second side is pressed together on the second curved edge；
S5, lift the pressing device 1, and pressing device 1 is returned on the position of the first tangent line, and pressing device 1 is again
Compress the adhesive film and moved along the outer surface of the first curved edge, the first side of adhesive film is pressed together on the first arc-shaped side
On edge.
As can be seen from the above description, the beneficial effects of the present invention are：The present invention first rotates adhesive film before fitting, makes stickup
Film is a certain included angle with camber display screen to be fit, and the initial position using the phase tangent line of the first side as pressing, at this time
The first side of adhesive film is in vacant state, will not encounter camber display screen, and center section and second side are in and stick up
The state of rising, will not encounter camber display screen, therefore will not produce the bad phenomenons such as bubble in fitting；Since initial position
Pressing device is moved in one direction, is realized the fitting of mid-plane and the second curved edge, is then returned initial position
The fitting of the first curved edge can be completed by moving pressing device in the opposite direction, and whole fitting process can not only ensure curved surface
Good fitting quality of the display screen especially at the curved edge of both sides, and the method for adhering film can be full-automatic by machine
Complete, it is not necessary to manually participate in, be greatly improved efficiency, save human cost.
Further, step S0 is further included before step S1：The adhesive film is drawn with vacuum absorption device 2, and is made
Expose outside vacuum absorption device 2 first side of adhesive film.
Seen from the above description, adhesive film is drawn with vacuum absorption device, not only adhesive film will not be caused to damage, but also
Adhesive film easily departs from from adsorbent equipment so as to be bonded with display screen during pressing；Expose the first side of adhesive film
Outside vacuum absorption device, position and press into the start of line at the first tangent line easy to pressing device.
Further, the step S0 is further included：The position of vacuum absorption device 2 is adjusted, is made on vacuum absorption device 2
Adhesive film aligns with camber display screen 3 to be pasted.
Seen from the above description, vacuum absorption device can be installed on XYZT motion platform, step S1 it
Before, the position of vacuum absorption device is adjusted, ensures the fitting regularity of film.
Further, the pressing device 1 is idler wheel mechanism, and the idler wheel mechanism includes cylinder and is connected to the pressure of cylinder
Roller is closed, in the bonding processes described in step S2-S5, the pressing roller compression is on the adhesive film.
Seen from the above description, pressing roller rolls on adhesive film, adhesive film can be pressed together on camber display screen, presses
Closing roller can not only avoid scratching adhesive film, and pressing roller can preferably complete the pressing at curved edge.
Further, the idler wheel mechanism further includes back-up roller wheel, and the back-up roller wheel is rolled with the pressing roller and connect
Touch, pressing roller is located at the lower section of back-up roller wheel, and the diameter of back-up roller wheel is more than the diameter of the pressing roller.
Seen from the above description, because existing camber display screen is chiefly used in handheld device, and the curved surface in handheld device
The curved edge curvature of display screen is smaller, and press that the diameter of roller has to do smaller can preferably complete arc-shaped side
Pressing at edge, the smaller roller rigidity of diameter easily occur bending and deformation with regard to smaller, are unfavorable for the pressing of adhesive film, and our
Method sets a back-up roller wheel being relatively large in diameter to be in rolling contact therewith in the top of pressing roller, can play support to pressing roller
Effect, avoids pressing roller stress deformation in bonding processes.
Further, the radius of the pressing roller is 3-4mm.
Further, step S40 is further included between the step S4 and S5：After the pressing for completing the second curved edge,
Pressing device 1 is set to keep original moving direction persistently to move forward, so that pressing device 1 is separated with adhesive film.
Seen from the above description, the adhesive film that above-mentioned steps can avoid having been pressed on the second curved edge is by band again
Get up.
Further, in the step S1, the second side of the adhesive film is acclivitous relative to first side
Angle is 10-20 °.
Seen from the above description, the angle of inclination of the scope is optimum tilt angle, has not only facilitated the pressing of pressing device, but also
It can ensure during pad pasting, the adhesive film not pressed will not encounter camber display screen.
Further, in the step S3, the translational speed of the pressing device 1 is 80-120mm/s；In step S4
In step S5, the translational speed of the pressing device 1 is 15-20mm/s.
Seen from the above description, step S3 is the pressing of mid-plane, and the pressing in plane is easier to, and can properly increase pressure
Sum velocity, improves pressing efficiency；Step S4 and S5 are the pressing of curved edge, and the pressing in cambered surface easily occurs being bonded undesirable
Phenomenon, can appropriate slow-down, ensure fitting quality.
