Abstract
The invention provides a curved surface laminating device which comprises a laminating head, a carrying platform, a first driving unit and a fluid source. The body of the attaching head driven by the first driving unit and the elastic attaching piece form a cavity together. The elastic attaching member has a first attaching portion with a smaller Young's modulus and a second attaching portion with a larger Young's modulus. A fluid source is connected to the chamber for generating first and second fluid pressures into the chamber in stages. When the pressure of the fluid source is increased to the first fluid pressure, the first bonding portion elastically deforms to press a portion of the soft membrane to be bonded to the curved surface object to be bonded on the stage. After the fluid source is increased to the second fluid pressure, the second bonding portion presses the soft film until the soft film is completely bonded to the curved surface object to be bonded. Therefore, the mould does not need to be changed by matching with different curved-surface attached objects, and air bubbles can be eliminated.
Description
Technical Field
The present invention relates to a bonding apparatus, and more particularly, to a curved surface bonding apparatus for a film.
Background
The conventional film laminating apparatus usually uses a method of transferring a soft film to a flat stage, and then correcting the soft film to a predetermined reference position and positioning the film. And then another hard object to be bonded, the shape of which is a plane, is placed at the specified reference position of another plane carrier, the relative position of the plane carrier is adjusted to enable the reference of the membrane and the hard object to be bonded to be superposed or reach the target difference, and then a cylindrical shaft-shaped rubber roller is used for continuously rolling at a certain height and under a certain pressure, so that the bonding between the products is completed.
If the membrane sticking device is used for sticking the membrane on the upper surface of the mouse with the biaxial curved surface, an upper cover plate with the appearance similar to that of the upper surface of the mouse is required to be manufactured firstly. Then, the soft film is placed on the inner side of the upper cover plate. And then, the soft membrane on the inner side of the upper cover plate is attached to the upper surface of the mouse. However, bubbles are easily generated in the attaching method, and the upper cover plate needs to be designed according to the mold opening of different product shapes. Therefore, the poor bonding effect often requires much mold opening and assembly cost and time. In addition, because the upper cover plate is hard, the upper cover plate is easy to collide with the mouse, and the surface of the mouse is damaged.

Fig. 1 is a perspective view of a curved surface laminating apparatus according to an embodiment of the present invention. Referring to fig. 1, the curved surface bonding apparatus 100 includes a bonding head 110, a carrier 120, a first driving unit 130, and a fluid source 140. The bonding heads 110 are located above the carrier 120 and opposite to each other. A curved surface object to be bonded 60 is disposed on the carrier 120, and a soft film 50 is disposed between the bonding head 110 and the curved surface object to be bonded 60. The first driving unit 130 and the fluid source 140 are connected to the fitting head 110. The first driving unit 130 is configured to drive the bonding head 110 to move toward the stage 120 in a first direction D1 to move closer to or away from the stage 120, and the fluid source 140 generates a fluid pressure to the bonding head 110 to bond the soft film 50 to the curved object 60. In this embodiment, the first driving unit 130 is a pneumatic cylinder or a hydraulic cylinder, and the bonding head 110 may be disposed on a piston portion of the pneumatic cylinder or the hydraulic cylinder to drive the bonding head 110 to move toward or away from the stage 120. However, in another embodiment not shown, the first driving unit 130 can also be implemented by other structures capable of driving the bonding head 110 to move, such as: motors, linkages, gears, etc., but are not limited thereto.
In detail, the fitting head 110 includes a body 112 and an elastic fitting member 114. The elastic fitting member 114 is connected to the body 112. The body 112 and the elastic fitting 114 together form a chamber C. In this embodiment, the body 112 is a hollow cylinder with a lower opening, and the elastic fitting member 114 is disposed below the body 112 and covers the lower opening of the body 112 to form a closed cavity C. The carrier 120 is disposed at a position facing the elastic fitting member 114. The soft film 50 is disposed between the curved adherend 60 and the elastic attachment member 114. The fluid source 140 is connected to the chamber C for generating fluid pressure to the chamber C in stages to drive the elastic fitting member 114 to deform and push the soft membrane 50 to fit the curved adherend 60. It is worth mentioning that the method of stepwise pressurization can also avoid the uneven thickness of the film material and the generation of bubbles.
Fig. 2 is a top view of the elastic fitting member of fig. 1. Referring to fig. 1 and fig. 2, the elastic fitting member 114 has a first fitting portion 114A and a second fitting portion 114B. The young's modulus of the first bonded portion 114A is smaller than the young's modulus of the second bonded portion 114B. Young's modulus E ═ σ/, where σ denotes forward stress and denotes forward strain. That is, when the first bonding portion 114A and the second bonding portion 114B are subjected to the same stress, the strain of the first bonding portion 114A is larger than that of the second bonding portion 114B. The first fitting portion 114A may be located at the center of the second fitting portion 114B, and the first fitting portion 114A and the second fitting portion 114B may be substantially designed as concentric circles, but not limited thereto. In the embodiment, the elastic attachment member 114 may be a thermoplastic elastomer (TPE), and may be selected from any one of styrene thermoplastic elastomers (TPE-S and SBC), polyolefin thermoplastic elastomers (TPO), vulcanized rubber thermoplastic elastomers (TPV), polyurethane thermoplastic elastomers (TPU), or polyester thermoplastic elastomers (TPE-E) and polyamide thermoplastic elastomers (TPE-a), wherein the resilience of the polyester thermoplastic elastomers is the best.
In addition, the size, shape, relative position relationship or proportional relationship of the first attaching portion 114A and the second attaching portion 114B may correspond to the shape of the curved surface attached object 60. For example, the size, shape, relative position relationship or proportional relationship of the first attaching portion 114A may correspond to a most convex point or a most concave point of the curved surface attached object 60, and the second attaching portion 114B may correspond to other portions of the curved surface attached object 60. In the present embodiment, the most convex point of the curved surface material to be bonded 60 is located substantially at the center, and therefore the first bonding portion 114A is designed to correspond to the center of the second bonding portion 114B. However, in another embodiment (not shown), the shape (similar to the curved surface object 60) and composition of the elastic attachment member 114 can be selected according to the attachment requirement.
In the present embodiment, the curved adherend 60 is, for example, a lens and may have a biaxial curved surface, and the elastic attachment member 114 is a planar elastic attachment member. In other words, in the present embodiment, the flexible film 60 is bonded to the curved surface object 60 by the plate-shaped elastic bonding material 114. It should be noted that, since the elastic attachment member 114 has elasticity, when the soft membrane 50 is pressed and attached to the curved object 60, the shape of the curved object 60 can be completely matched. Therefore, the curved surface bonding apparatus 100 can be applied to objects having various surface curvatures and can prevent the curved surface to be bonded 60 (e.g., a lens) from being damaged by pressure. In addition, the elastic attachment member 114 does not need to be specially curved, and further does not need to be matched with the shape of the object 60 to be attached with a different curved surface to replace the mold of the cover plate. Therefore, the single production line can simultaneously laminate different curved surfaces without replacing the cover plate.
Generally, a single-axis curved surface is like holding two ends of a piece of paper by hands to naturally hang down (presenting a U shape), and at the moment, the paper only has a curvature in one direction and still presents a straight line in the other direction. Compared with the uniaxial curved surface, the biaxial curved surface of the curved surface attached object 60 has curvature in the directions of a major axis a1 and a minor axis a2, wherein the major axis a1 and the minor axis a2 are perpendicular to each other. For example, a biaxial curved surface can be seen on a common mouse appearance.
In addition, for the convenience of alignment, the curved surface laminating apparatus 100 may further include a guide rail 150 and a second driving unit (not shown). The first driving unit 130 is movably disposed on the guide rail 150. The second driving unit is connected to the first driving unit 130, and may be a stepping motor or a servo motor, for driving the first driving unit 130 to move left and right along the guide rail 150 in a second direction D2. The second direction D2 can be perpendicular to the first direction D1 and corresponds to a horizontal direction and a vertical direction, respectively. In this way, the attaching head 110 can move left and right along the guide rail 150 along with the second driving unit to move the elastic attaching member 114 to a position facing the stage 120, so that the positions of the elastic attaching member 114 and the curved object 60 correspond to each other. In the present embodiment, the second driving unit is not limited to be a stepping motor or a servo motor.
FIG. 3 is a line graph depicting the phased generation of fluid pressure by the fluid source of FIG. 1. In fig. 3, the horizontal axis represents time and the vertical axis represents fluid pressure generated by the fluid source, but it should be noted that the scale merely represents relative conditions for reference, and is not an actual numerical value. Referring to fig. 1 and 3, the fluid source 140 may be a pneumatic source or a hydraulic source and is connected to the chamber C through a line T. Thus, the fluid source 140 can generate a first fluid pressure P1 and a second fluid pressure P2 into the chamber C in stages. The first fluid pressure P1 is less than the second fluid pressure P2, and can be set corresponding to the young's modulus of the first bonding portion 114A and the young's modulus of the second bonding portion 114B, respectively. When the pressure of the fluid source 140 is increased to the first fluid pressure P1, the first bonding portion 114A elastically deforms to press a first portion of the soft membrane 50 against the curved adherend 60. When fluid source 140 is increased to second fluid pressure P2, second bonding portion 114B elastically deforms and first driving unit 130 simultaneously drives bonding head 110 toward stage 120, pressing a second portion of soft film 50 against curved object to be bonded 60 until soft film 50 is completely bonded to curved object to be bonded 60.
Fig. 4A to 4D are cross-sectional views illustrating a bonding process performed by the curved surface bonding apparatus of fig. 1, where the bonding process can refer to the fluid pressure variation of fig. 3. Referring to fig. 1 and fig. 4A, firstly, the curved surface object to be bonded 60 is disposed on the carrier 120, and the soft film 50 is disposed between the curved surface object to be bonded 60 and the bonding head. At this point, a first stage of pressurization may occur, with chamber C being gradually pressurized by fluid source 140 until a first fluid pressure P1. During or before the boosting process, the guide rail 150 and the second driving unit can drive the first driving unit 130 and the bonding head 110 to move left and right in the second direction D2, so that the elastic bonding member 114 is accurately aligned with the curved object to be bonded 60.
Referring to fig. 1 and 4B, when the interior of the chamber C reaches the first fluid pressure P1, the first engaging portion 114A elastically deforms. At this time, the first bonding portion 114A contacts and presses the first portion of the soft film 50 to the most convex point of the curved surface object 60. Following the second stage of pressurization, chamber C is gradually pressurized by fluid source 140 until the first fluid pressure P2.
Referring to fig. 1 and 4C again, when the interior of the chamber C reaches the second fluid pressure P2, the second fitting portion 114B is elastically deformed. At this time, the first driving unit 130 can drive the bonding head 110 to move along the first direction D1 toward the carrier 120.
Referring to fig. 1 and 4D, after the second fluid pressure P2 is reached inside the chamber C, the third stage of pressure increase may be performed. In detail, while the first driving unit 130 drives the bonding head 110 to move toward the stage 120 along the first direction D1, the chamber C may be pressurized by the fluid source 140 at the same time, so that the second portion of the soft film 50 is bonded to the curved surface bonded object 60 until the soft film 50 is completely bonded to the curved surface bonded object 60.
It should be noted that the process of attaching the soft film 50 to the curved surface object 60 is to start from the most protruding point and to apply a step-wise pressurization until the soft film is completely attached, so as to avoid uneven thickness of the film of the soft film 50 and avoid generation of bubbles. In addition, one skilled in the art can select materials of the first attaching portion 114A and the second attaching portion 114B of the elastic attaching member 114 according to different expansion requirements, and design the size, shape, relative position relationship or proportional relationship.
Fig. 5 is a cross-sectional view of a curved surface laminating device according to another embodiment of the present invention. Referring to fig. 1 and 5, the curved surface laminating apparatus 200 of the present embodiment is similar to the curved surface laminating apparatus of fig. 1, and the same or similar elements are denoted by the same reference numerals and are not repeated herein. In this embodiment, the curved surface bonding apparatus 200 further includes a reel device 260 disposed between the bonding head 110 and the stage 120 for disposing and rolling the soft membrane 50. For example, the reel device 260 may be provided with a protection film 70, and the plurality of soft films 50 are attached to the protection film 70 by electrostatic absorption or low viscosity.
In addition, a glue layer (not shown) may be disposed on the other side (i.e., the lower surface) of the flexible film 50 opposite to the protection film 70, so as to be adhered to the curved object 60 by the glue layer itself. In this embodiment, the curved surface bonding apparatus 200 further includes a heating unit (not shown) for allowing the gas of the fluid source 140 to be delivered to the chamber C at a constant temperature or directly heat the soft film 50 to reach the minimum bonding temperature of the adhesive layer, so that the soft film 50 can be effectively bonded to the curved surface to-be-bonded object 60.
In this embodiment, the curved surface laminating apparatus 200 further includes a fixing bracket 250 and a conveying belt 270. The conveyor 270 is provided with a plurality of carriers 120, and the carriers 120 are sequentially moved to positions corresponding to the bonding heads 110 for automated conveying and bonding. In this way, the bonding head 110 can be directly fixed on the fixing bracket 250, and the carrier 120 is directly moved by the conveyor belt 270, so that the bonding head 110 and the curved object 60 are relatively positioned. In another embodiment, not shown, the carrier 120 may also be disposed on a two-dimensional positioning platform, so as to perform more precise positioning.
Further, the curved surface laminating apparatus 200 may further include a cutting unit 280, and the cutting unit 280 may be, for example, a laser or a hob cutter. After the soft film 50 is attached to the curved object 60, the carrier 120 may be moved by the conveyor 270 in the second direction to a position corresponding to the cutting unit 280. In this way, the cutting unit 280 can cut the soft film 50 completely attached to the curved surface object 60. Note that, although the size of the soft film 50 of the present embodiment is larger than that of the curved surface object to be bonded 60, a cutting unit 280 may be provided. However, in another embodiment, not shown, if the soft film 50 conforms to the shape and size of the curved adherend 60, it is not necessary to cut it. That is, the curved surface laminating apparatus 200 may omit the cutting unit 280.
In summary, the curved surface attaching device of the above embodiment can attach the soft film to the curved surface attached object by the elastic attaching member, and can be used for attaching any shape without designing the upper cover plate according to the shape of different products. Therefore, the curved surface laminating device of the above embodiment does not need to consume additional mold opening, assembly cost and time. In addition, the elastic fitting piece is provided with a first fitting part and a second fitting part which have different Young moduli, so that the requirements of different expansion degrees can be met. Therefore, no matter the curved surface is concave or convex, the curved surface can be attached from the most concave or convex part of the object to be attached, thereby avoiding the generation of bubbles and having good attaching effect.
The above-described embodiments are merely illustrative of the technical spirit and features of the present invention, and the object of the present invention is to enable those skilled in the art to understand the content of the present invention and to implement the same, and not to limit the scope of the present invention, i.e. all equivalent changes or modifications made in the spirit of the present invention should be covered in the scope of the present invention.
