Specific embodiment
To explain the technical content, the achieved purpose and the effect of the present invention in detail, below in conjunction with embodiment and cooperate attached
Figure is explained.
The most critical design of the present invention is: rotating adhesive film before fitting, make adhesive film and curved-surface display to be fit
Screen 3 is a certain included angle, and using the phase tangent line on right side as the initial position of pressing, 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.
Please refer to Fig. 1 to Fig. 4, a kind of method for adhering film of camber display screen, comprising steps of
S1, rotation adhesive film, tilt the second side of adhesive film upwards relative to first side, the first side,
Second side is corresponding with the first curved edge of camber display screen 3, the second curved edge respectively；
S2, the adhesive film is pushed using pressing device 1, adhesive film is made to be in contact first with the first tangent line, described first
Tangent line is the phase tangent line of the first curved edge and mid-plane on camber display screen 3；
S3, pressing device 1 persistently compress the adhesive film and the direction movement to close second curved edge, by adhesive film
It is pressed together in mid-plane, until reaching at the second tangent line；Second tangent line be camber display screen 3 on the second curved edge with
The phase tangent line of mid-plane；
S4, pressing device 1 continue to compress the adhesive film and move along the outer surface of the second curved edge, by adhesive film
Second side is pressed together on the second curved edge；
S5, the pressing device 1 is lifted, and returns to pressing device 1 on the position of first tangent line, pressing device 1 is again
It compresses the adhesive film and is 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 to paste
Film is a certain included angle with camber display screen to be fit, and using the phase tangent line of the first side as the initial position of pressing, at this time
The first side of adhesive film is in vacant state, will not encounter camber display screen, and middle section and second side are in and stick up
The state of rising will not encounter camber display screen, therefore will not generate 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
Moving pressing device in the opposite direction can be completed the fitting of the first curved edge, and entire fitting process can not only guarantee curved surface
Good fitting quality of the display screen especially at the curved edge of two sides, and the method for adhering film can pass through machine full-automation
It completes, does not need manually to participate in, be greatly improved efficiency, save human cost.
Further, further include step S0 before step S1: drawing the adhesive film with vacuum absorption device 2, and make
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 is easy to be detached to bond with display screen from adsorbent equipment during pressing；Expose the first side of adhesive film
Outside vacuum absorption device, starting positioning pressing is carried out at the first tangent line convenient for pressing device.
Further, the step S0 further include: the position of adjustment vacuum absorption device 2 makes on vacuum absorption device 2
Adhesive film is aligned with camber display screen 3 to be pasted.
Seen from the above description, vacuum absorption device can be mounted on an XYZT motion platform, step S1 it
Before, the position of vacuum absorption device is adjusted, guarantees the fitting regularity of film.
Further, the pressing device 1 is idler wheel mechanism, and the idler wheel mechanism includes cylinder and the pressure for being connected to cylinder
Idler wheel 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 idler wheel rolls on adhesive film, adhesive film can be pressed together on camber display screen, presses
Closing idler wheel can not only avoid scratching adhesive film, and pressing idler wheel 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 connects with pressing idler wheel rolling
Touching, pressing idler wheel are located at the lower section of back-up roller wheel, and the diameter of back-up roller wheel is greater than the diameter of the pressing idler wheel.
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 what the diameter for pressing idler wheel had to do smaller can preferably complete arc-shaped side
Pressing at edge, the smaller idler wheel rigidity of diameter are easy to happen bending deformation with regard to smaller, are unfavorable for the pressing of adhesive film, and our
Method is arranged a back-up roller wheel being relatively large in diameter in the top of pressing idler wheel and is in rolling contact therewith, can play support to pressing idler wheel
Effect avoids pressing idler wheel stress deformation during the pressing process.
Further, the radius of the pressing idler wheel is 3-4mm.
Further, further include step S40 between the step S4 and S5: after the pressing for completing the second curved edge,
Make pressing device 1 that original moving direction be kept persistently to move forward, so that pressing device 1 is mutually 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 tilt angle of the range is optimum tilt angle, has not only facilitated the pressing of pressing device, but also
It can guarantee during pad pasting, the adhesive film not pressed will not encounter camber display screen.
Further, in the step S3, the movement speed of the pressing device 1 is 80-120mm/s；In step S4
In step S5, the movement 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
Speed is closed, pressing efficiency is improved；Step S4 and S5 are the pressing of curved edge, and it is undesirable that the pressing in cambered surface is easy to appear fitting
Phenomenon, can appropriate slow-down, guarantee fitting quality.
Embodiment one
