Detailed Description
The present invention will be described in further detail with reference to the accompanying drawings and examples. It is to be understood that the specific embodiments described herein are merely illustrative of the invention and are not limiting of the invention. It should be further noted that, for the convenience of description, only some of the structures related to the present invention are shown in the drawings, not all of the structures.
Fig. 1 is a schematic perspective view of an adsorption platform according to an embodiment of the present invention, fig. 2 is a schematic top view of the adsorption platform according to the embodiment of the present invention, fig. 3 is a schematic cross-sectional view along AA' in fig. 1, and referring to fig. 1, fig. 2 and fig. 3, an adsorption platform 100 includes an adsorption flat plate 10 and at least one spacer 20. The adsorption flat plate 10 is used to adsorb the thin film 30 to be attached. The film 30 to be attached may be a 3D film, and the 3D film may include a plurality of cylindrical lenses arranged in parallel. The spacer 20 is fixed to one side of the adsorption flat plate 10. After the film 30 to be attached is adsorbed, the spacer 20 is positioned between the adsorption flat plate 10 and the film 30 to be attached, and the spacer 20 jacks up the film 30 to be attached, so that a gap 31 is formed between at least one side of the film 30 to be attached and the spacer 20 and the adsorption flat plate 10.
In the embodiment of the invention, the adsorption platform comprises an adsorption flat plate and a spacer positioned on one side of the adsorption flat plate, the spacer covers a part of the area of the adsorption flat plate, and due to the existence of the spacer, after the thin film to be attached is adsorbed, the spacer jacks up the thin film to be attached, so that a gap is formed between the thin film to be attached and at least one side of the spacer and the adsorption flat plate, and the adsorption force of the adsorption flat plate on the thin film to be attached is reduced. Further, the pulling force of the film to be attached in the subsequent attaching process can be reduced, so that the film to be attached is prevented from being damaged due to the large pulling force. The adsorption force of the adsorption flat plate on the film to be attached mainly refers to an acting force vertical to the plane of the film, and the pulling force on the film to be attached mainly refers to an acting force along the plane of the film.
Alternatively, referring to fig. 2, the film to be attached is omitted from fig. 2 for clarity, and the spacer 20 is in the form of a strip. The included angle theta between the extending direction of the spacer 20 and the attaching direction is less than or equal to a preset value, and the preset value is less than 90 degrees, namely theta is less than 90 degrees. When the film 30 to be attached is attached, the film 30 to be attached is gradually separated from the adsorption flat plate 10 along the attaching direction. In fig. 2, the bonding direction is the X-axis negative direction. Since the strip-shaped spacer 20 is easy to manufacture and attach, the shape of the spacer 20 is strip-shaped in the embodiment of the present invention. It should be noted that, in other embodiments, the spacer 20 may also have other shapes, which is determined according to the product requirements, and this is not limited by the embodiments of the present invention.
Alternatively, referring to fig. 2, the adsorption platform 100 includes a plurality of spacers 20 arranged in parallel and spaced apart. The strip-shaped spacers 20 are arranged at regular intervals, and all the strip-shaped spacers 20 extend in the same direction, which is a relatively simple arrangement mode, and is beneficial to simplifying the manufacturing process of the adsorption platform 100.
Fig. 4 is a schematic top view of another adsorption platform according to an embodiment of the present invention, and referring to fig. 4, for clarity, a film to be attached is omitted from fig. 4, and an extending direction of the spacer 20 is the same as an attaching direction. That is, the spacer 20 extends in the X-axis direction, and θ is 0 °. It is understood that, since the film 30 to be attached is gradually separated from the adsorption flat plate 10 in the X-axis negative direction, the film 30 to be attached is mainly subjected to a pulling force in the X-axis direction (the X-axis direction here includes the X-axis positive direction and the X-axis negative direction). The larger the included angle theta between the extending direction of the spacer 20 and the attaching direction is, the easier the edge of the spacer 20 blocks the movement of the film 30 along the X-axis direction; the smaller the angle θ between the extending direction of the spacer 20 and the attaching direction is, the less easily the edge of the spacer 20 blocks the movement of the film 30 in the X-axis direction. In the embodiment of the invention, the extending direction of the spacer 20 is consistent with the attaching direction, so that the pulling force applied to the film 30 to be attached is further reduced, and the film 30 to be attached is prevented from being damaged due to the larger pulling force.
Fig. 5 is a schematic top view of another adsorption platform according to an embodiment of the present invention, and referring to fig. 5, for clarity, a film to be attached is omitted in fig. 5, and an adsorption flat plate 10 includes a plurality of adsorption holes 11 arranged in an array. That is, the adsorption plate 10 is provided with a plurality of adsorption holes 11. The adsorption plate 10 may be a vacuum adsorption plate. The spacer 20 is not overlapped with the adsorption holes 11, so that the adsorption of the adsorption holes 11 to the film 30 to be attached is not affected. The strip-shaped spacer 20 is illustrated in fig. 5 as an example, and is not limited to the embodiment of the present invention, and in other embodiments, the spacer 20 may have other shapes as long as the spacer 20 is not overlapped with the adsorption holes 11.
Alternatively, referring to fig. 5, the adsorption flat plate 10 includes a plurality of adsorption holes 11 arranged in an array. That is, the adsorption plate 10 is provided with a plurality of adsorption holes 11. The adsorption plate 10 may be a vacuum adsorption plate. The width H1 of the spacer 20 is equal to or less than the distance H2 between the edges of two adjacent adsorption holes 11 in the direction perpendicular to the attaching direction (i.e., the Y-axis direction). Along the Y-axis direction, any spacer 20 is positioned between two adjacent rows of adsorption holes 11, the spacer 20 is not overlapped with the adsorption holes 11, and the adsorption of the adsorption holes 11 on the film 30 to be attached is not influenced. Wherein the row direction refers to the X-axis direction.
Fig. 6 is a schematic top view of another adsorption platform according to an embodiment of the present invention, referring to fig. 3 and fig. 6, for clarity, a film to be attached is omitted in fig. 6, the spacers 20 are in a grid shape, and the grid-shaped spacers 20 are located on one side of the adsorption flat plate 10. After the film 30 to be attached is adsorbed, the latticed spacer 20 is positioned between the adsorption flat plate 10 and the film 30 to be attached, and can jack up the film 30 to be attached, so that a gap 31 is formed between at least one side of the film 30 to be attached and the spacer 20 and the adsorption flat plate 10. The spacer 20 may also be circular, elliptical, or spiral in shape.
Fig. 7 is a schematic top view of another adsorption platform according to an embodiment of the present invention, referring to fig. 7, for clarity, a film to be attached is omitted in fig. 7, a spacer 20 is in a grid shape, and an adsorption flat plate 10 includes a plurality of adsorption holes 11 arranged in an array. The spacer 20 is not overlapped with the adsorption holes 11, so that the adsorption of the adsorption holes 11 to the film 30 to be attached is not affected.
Alternatively, referring to fig. 1-7, the spacer 20 is an adhesive tape, the adhesive tape is fixedly bonded to the adsorption plate 10, and a side surface of the adhesive tape 20 facing away from the adsorption plate 10 is smooth. The side of the adhesive tape contacting the adsorption flat plate 10 has adhesiveness, so that the adhesive tape and the adsorption flat plate 10 are adhesively fixed together. The side of the tape in contact with the film 30 to be attached has no stickiness, so that the film 30 to be attached is not adhered, and the damage of the film 30 to be attached by the tape is prevented.
Alternatively, referring to FIGS. 1-7, the spacer 20 has a thickness of 0.5-3 mm. The reason for this is that if the thickness of the spacer 20 is too thin, the gap at the edge of the spacer 20 is small, and the purpose of good air circulation cannot be achieved; if the thickness of the spacer 20 is too thick, when the film 30 to be attached is adsorbed and fixed by the adsorption platform 100, the film 30 to be attached is jacked up too high, and the film 30 to be attached is severely shrunk inwards, so that the attachment precision of the product is affected.
Fig. 8 is a schematic structural diagram of a film attaching system according to an embodiment of the present invention, referring to fig. 1-7 and fig. 8, the film attaching system is used for attaching a film 30 to be attached to a substrate 50, wherein the substrate 50 may be a glass substrate, for example. The film attaching system includes the suction platform 100 and the roller 40 in any of the above embodiments. When the film 30 to be bonded is bonded, the roller 40 presses the surface of the film 30 to be bonded on the side away from the substrate 50 along the bonding direction (X-axis negative direction), and the film 30 to be bonded is gradually separated from the adsorption flat plate 10 along the bonding direction.
In the attaching process, the adsorption platform 100 adsorbs and fixes the film 30 to be attached (specifically, the adsorption flat plate 10 in the adsorption platform 100 adsorbs and fixes the film 30 to be attached through the spacer 20, after the adsorption flat plate 10 adsorbs the film 30 to be attached, the spacer 20 is located between the adsorption flat plate 10 and the film 30 to be attached, and the spacer 20 jacks up the film 30 to be attached, so that a gap 31 is formed between the film 30 to be attached and at least one side of the spacer 20 and the adsorption flat plate 10), and the film 30 to be attached is moved above the substrate 50, the roller 40 presses one end of the film 30 to be attached to attach the end to the substrate 50, the adsorption platform 100 and the roller 40 move along the negative direction of the X axis (or the substrate 50 moves along the positive direction of the X axis), so that the film 30 to be attached is gradually separated from the adsorption platform 100 and attached to the substrate 50 until all the film 30 to be attached is completely attached to the substrate 50. In the whole attaching process, under the action of the gap 31, when the adsorption flat plate 10 and the attached film 30 are gradually separated, the pulling force between the adsorption flat plate 10 and the attached film 30 is smaller, correspondingly, when the substrate 50 and the film 30 are attached, the pulling force between the adsorption flat plate 10 and the attached film 30 is also reduced due to the reduction of the pulling force between the adsorption flat plate 10 and the attached film 30, so that the film 30 is prevented from being seriously pulled, a lens in the film 30 is stretched, and adverse effects are caused on subsequent three-dimensional display. In addition, the present embodiment can also improve the bonding efficiency between the film 30 and the substrate 50.
It is to be noted that the foregoing is only illustrative of the preferred embodiments of the present invention and the technical principles employed. It will be understood by those skilled in the art that the present invention is not limited to the particular embodiments described herein, but is capable of various obvious modifications, rearrangements, combinations and substitutions as will now become apparent to those skilled in the art without departing from the scope of the invention. Therefore, although the present invention has been described in greater detail by the above embodiments, the present invention is not limited to the above embodiments, and may include other equivalent embodiments without departing from the spirit of the present invention, and the scope of the present invention is determined by the scope of the appended claims.
