The invention relates to a bonding technology, in particular to a pressure bonding method and device for a multi-layer object.

Generally, a multi-layered object refers to a form in which a thin plate, a glue layer, a film, and the like are attached to each other. At present, common touch panels, touch display devices, solar panels, etc. are all one of the multi-layer objects. For example, the touch panel can be a multi-layer object composed of a cover glass and a touch substrate. The protective glass and the touch substrate are further bonded together by a pressure sensitive adhesive (PSA, hereinafter referred to as pressure sensitive adhesive).

Please refer to FIG. 1 , which is a schematic top view of a conventional method for bonding a multi-layer object. The conventional method of bonding the multi-layered article 200 is generally to place the pressure sensitive adhesive between any two layers of the multi-layered article 200, and then pass through the pressing device 100 at a time to be relatively parallel to the multi-layered article 200. The position of the side 211 of the pressed surface (upper surface) begins to be pressed in the Y direction to the other parallel opposite side 212 to complete the fit. During the bonding process, bubbles are inevitably generated, so that the plurality of bonding bubbles remain in the multi-layered object 200, thereby affecting the bonding quality and product yield.

Therefore, in the bonding technology of multi-layer objects, how to effectively remove the bonding bubbles to effectively improve the bonding quality and product yield is a subject worthy of research and development.

Wherein the above stratified object comprises at least two substrates, and the two substrates comprise an adhesive between them. Wherein: the adhesive is a pressure sensitive adhesive film; the bonding surface of at least one of the two substrates comprises a frame structure.

The type of the above-mentioned multi-layered object may be a polygonal structure, and in particular may be a quadrilateral structure.

A contact line formed by the contact element when the pressure receiving surface of the multi-layer object is pressed is perpendicular or parallel to a pair of angles of the pressure surface of the multi-layer object.

The contact element is a roller that presses the multi-layer object in a rolling manner. Or the contact element is a pressure plate that slides the multi-layer object in a sliding manner.

For this reason, the present invention provides a multi-layer object pressing and bonding device, comprising: a platform carrying a multi-layer object; a contact element disposed on one side of the platform; And a driver translating at least one of the platform and the contact element such that the contact element and the multi-layer object are in close proximity to each other to form a contact pressure, and the contact element is from a pressure-receiving surface of the multi-layer object One of the end angles is pressed to A pair of corners of the corners complete the full surface contact of the pressed surface.

In a further implementation, the pressure applying device further includes: a jig disposed on the platform for receiving the multi-layer object. Wherein: the fixture further comprises a fixing member for fixing the multi-layer object; the platform further comprises a positioning mechanism for adjusting and fixing the position of the jig.

In summary, the method and apparatus for pressing and laminating the multi-layer object provided by the present invention can effectively eliminate the residual of the bonding bubbles, thereby increasing the bonding quality and the product yield.

The specific implementation details of the above-mentioned methods and devices and the specific implementation details thereof will be described with reference to the following embodiments and drawings.

Embodiments of the present invention are directed to the use of a multi-layer article pressing and bonding method and apparatus thereof to achieve lamination of a multi-layer object, and by changing the configuration between the multi-layer object and the contact element, between the multi-layer object and the contact element The oblique arrangement is formed first, and then the touch bonding is performed, thereby solving the problem of the conforming bubbles generated when the multi-layer object is attached.

In addition, the multi-layer object type mentioned in the embodiment of the present invention may be a polygonal structure, especially a quadrilateral structure, such as a rectangle, a parallelogram, a diamond, a rectangle, etc., which are connected by four sides (line segments). The formed form, wherein the class rectangle may further comprise a deformed shape such as a chamfered rectangle, a rounded rectangle, or an arced rectangle.

Please refer to FIG. 2a and FIG. 2b together, which are schematic cross-sectional views of the embodiment before and after the stratified object of the present invention is subjected to contact pressure. The multi-layered article 10 of the present embodiment is, for example, comprising at least two substrates (such as a first substrate 10a and a second substrate 10b) and an adhesive 10c. Wherein the first substrate 10a is adjacent to the second substrate 10b Further, a frame-shaped structure 10d is formed on the surface, and the frame-shaped structure 10d is substantially a frame-shaped body having a thickness, such as an ink frame made by printing. In addition, the first substrate 10a and the second substrate 10b are not limited to a single layer structure in actual design, and may be a multilayer structure or a coating structure.

The adhesive 10c is disposed between the two substrates 10a and 10b, and the substrates 10a and 10b are respectively referred to as the bonding surfaces 101 and 102 in contact with the surface of the adhesive 10c. In addition, the adhesive of the embodiment of the present invention is designed, for example, by using two-sided Pressure Sensitive Adhesives (PSA), whereby when the two substrates 10a and 10b are actually pressed, the adhesive 10c is The pressure is applied to adhere to the bonding faces 101 and 102 of the two substrates 10a and 10b, thereby completing the bonding of the laminated article 10.

As can be seen from FIG. 2a and FIG. 2b, the present embodiment is a first substrate 10a having a frame structure 10d, an adhesive 10c and a full-plane second bottom on the laminated structure of the laminated object 10. The material 10b is stacked. The adhesive 10c is designed, for example, by using a full-surface pressure sensitive adhesive film. Of course, in other embodiments, the adhesive 10c may also be designed with a frame-shaped pressure sensitive adhesive film.

In addition, in other embodiments in which the drawings are not drawn, the multi-layer object may be stacked by a full-plane first substrate, a frame-shaped adhesive, and a full-plane second substrate. In still other embodiments, the multi-layered object may be stacked by a full-plane first substrate, a frame-shaped adhesive, and a frame-shaped second substrate. Furthermore, in a further modified embodiment, the multi-layered article may also be formed by stacking a full-plane first substrate and a frame-shaped adhesive substrate, wherein the frame-shaped adhesive substrate is In addition to being used as a substrate, it is directly viscous and viscous on the surface close to the first substrate.

In order to facilitate the description of the method and apparatus for applying pressure on the multi-layered article 10 of the present invention, in the following embodiments, the multi-layer object 10 which is rectangular in projection in the pressed axial direction is exemplified, but the actual complex The layer object 10 is not limited thereto, and will be described first.

As shown in FIG. 2a and FIG. 2b, the multi-layer object 10 in this embodiment may be a touch panel, and the touch panel includes a protection substrate and a touch substrate, respectively corresponding to the first substrate. 10a and second substrate 10b. The protective substrate (the first substrate 10a) and the touch substrate (the second substrate 10b) respectively provide a bonding surface 101 and 102, and an adhesive 10c is disposed between the bonding surfaces 101 and 102 to protect the substrate. The substrate and the touch substrate can be integrated with each other by the adhesive 10c.

More specifically, the touch panel generally includes a viewing area and a shielding area surrounding the viewing area. Wherein, the shielding area is formed by a frame-shaped structure 10d, and the visible area surrounded by the frame-shaped structure 10d is formed as a frame groove 103. In other words, the area formed by the frame-shaped structure 10d will be the same as the original The bonding surface 101 of the protective substrate (first substrate 10a) has a height difference to form the frame groove 103 described above. In addition, the frame-shaped structure 10d is formed on the bonding surface 101 of the protective substrate (the first substrate 10a) by printing or other covering means by ink or other shielding medium for shielding the touch substrate ( A peripheral line (not shown) on the second substrate 10b).

It is to be noted that since the adhesive 10c of the present embodiment is designed using a pressure sensitive adhesive film, the thickness of the pressure sensitive adhesive film itself is usually larger than the height of the frame-shaped structure 10d. Therefore, as shown in FIG. 2a, the adhesive 10c is located between the protective substrate (the first substrate 10a) and the touch substrate (the second substrate 10b) in a sheet form before being touched by the touch panel, but is in contact with The control panel is touched Thereafter, as shown in FIG. 2b, the adhesive 10c is pressed against the frame groove 103 surrounded by the frame structure 10d at a portion corresponding to the visible area.

Therefore, based on the structure of the multi-layer object 10 presented by the touch panel, the present invention is improved by the relative position between a touch panel and a contact element (not shown) for convenient control. The overflow direction and position of the bonding bubbles generated between the bonding surfaces 101 and 102 and the adhesive 10c effectively reduce the bubble residue, and the touch panel is not subjected to the frame structure 10d during the entire touch bonding process. The difference in height formed by the frame groove 103 causes the received pressure to be inconsistent, thereby reducing the probability of generating regenerated bubbles after bonding.

Next, please further refer to FIG. 3 and FIG. 4a to separately illustrate a flow chart of the method for applying pressure bonding of the multi-layer object of the present invention and a schematic diagram of a dynamic top view configuration for performing the steps shown in FIG. It is to be noted that, as shown in the X-axis and the Y-axis of the rectangular coordinate system in FIG. 4a, the pressed axial direction of the multi-layer object 10 of the present embodiment belongs to the Z-axis, thereby illustrating the present embodiment. The projection of the stratified object 10 in the pressed axial direction (Z-axis) is rectangular, that is, corresponding to the shape of a pressed surface 11 of the stratified object 10.

The embodiment provides a method for pressing and bonding a multi-layer object 10. The multi-layer object 10 in this embodiment may also be a laminated layer of the touch panel to facilitate understanding. The pressing and bonding method comprises: feeding the multi-layered object 10, and then translating at least one of the contact element 20 and the multi-layered object 10 such that the contact element 20 and the multi-layered object 10 are close to each other to form a touch Pressing and causing the contact element 20 to be pressed from one of the first end corners 11a of a pressed surface 11 of the laminated article 10 to a pair of corners (second end angle 11d) of the first end angle 11a The entire surface of the pressed surface 11 is pressed. In other words It can be said that any side 12 of the pressed surface 11 of the multi-layer object 10 can form a non-orthogonal angle θ with a contact line 21 formed when the contact element 20 touches the multi-layer object 10.

Referring to the implementation steps shown in FIG. 3, the above technical means of the present embodiment can be specifically implemented through steps S1 to S3, wherein:

Step S1: Relatively oblique configuration.

In the embodiment shown in FIG. 4a, the multi-layer object 10 is bottomed on any of the first substrate 10a and the second substrate 10b, and is smoothly fed onto a platform, and at the first bottom. An adhesive 10c (for example, a pressure sensitive adhesive film) is placed between the material 10a and the second substrate 10b. The so-called feed on the platform means that the multi-layered article 10 is placed and fixedly disposed on the platform and disposed adjacent to the proximal side of the contact member 20. Accordingly, any side 12 of the pressure-receiving surface 11 of the multi-layer object 10 fed onto the platform can form a non-orthogonal angle θ with the contact line 21, thereby forming a slanting direction of the multi-layer object 10 and the contact element 20. The relationship of the configuration.

Specifically, the contact line 21 on the contact element 20 and the pressed surface 11 on the multi-layer object 10 are located on the same spatial plane S, and the included angle θ is substantially a plane angle θ; the spatial plane S There is essentially a planar triangular path R comprising a group of adjacent side paths R1, a pair of side paths R2 and a beveled path R3. The adjacent side path R1 is formed by the center line of the contact element 20 or the contact line 21; the oblique side path R3 is formed by the centroid 13 of the multi-layer object 10 or any side of the pressed surface 11 thereof. A derivative line 14 of 12 is formed; the pair of side paths R2 are present in a triangular space plane S surrounded by the adjacent side path R1 and the oblique side path R3.

Further, the angle θ is present in the contact line 21 and the layer Between any of the sides 12 of the pressed surface 11 of the article 10, and in the same plane, the corresponding relationship of the included angles θ is formed. In other words, the angle θ may be between the contact line 21 and the centroid 13 of the multi-layer object 10, and the corresponding relationship between the angles θ is formed on the same plane. However, the contact line 21 and the opposite side path R2 are excluded from each other in parallel, and the exclusion from each other includes the case where the contact line 21 and the opposite side path R2 are excluded from each other.

Generally, the above knowledge can be understood in a two-dimensional or three-dimensional right-angle coordinate system, whether the multi-layer object 10 is inclined and the contact element 20 is placed flat in the coordinate system, or the multi-layer object 10 is flat. And placing the contact element 20 obliquely in the coordinate system, so that any side 12 of the pressed surface 11 of the laminated object 10 and the contact line 21 of the contact element 20 can maintain a plane non-orthogonal angle The relative oblique relationship of the angle θ is set, and the opposite side path R2 exists.

The contact member 20 of the present embodiment is of a design employing a roller which is a freely rotatable free roller which presses the pressed surface 11 of the laminated article 10 in a rolling manner. Any position of the circumferential surface of the drum can be formed by tangentially forming a contact line 21, and the contact line 21 is parallel to the center line of the drum, so that the contact line 21 can be preset to be located on the circumferential surface of the drum. Any position of the line, and is specifically formed when the roller touches the multi-layer object 10. In another embodiment of the present invention, the contact member 20 can also adopt a design of a pressure plate and directly pass through the edge of the plate of the pressure plate as a portion of the pressure-contact layered object 10 to slide the composite object 10 in a sliding manner. The contact line 21 is formed by the pressed surface 11.

Step S2: translation close to each other.

In the embodiment shown in FIG. 4a, the position of the contact element 20 can be fixed, and the platform on which the multi-layer object 10 has been carried can be moved by the driving of a driver to make the multi-layer object on the platform. 10 translates towards the contact element 20 along the opposite side path R2, causing a translational approach between the multi-layer object 10 and the contact element 20 (as indicated by the dashed line with arrows in Figure 4a). The translation means that at least one of the multi-layered object 10 and the contact element 20 is seated in the spatial plane S.

In addition, it is generally known by those skilled in the art that if the platform is fixed and the touch panel 10 is not moved, the contact element 20 can be driven along the opposite path R2 toward the multi-layer object 10 through the driver. Moving, either by simultaneously or separately driving the multi-layer object 10 and the contact element 20 relative to each other along the opposite side path R2 through the same or different drivers, enables a close translation between the multi-layer object 10 and the contact element 20.

Step S3: Touching each other to the separation.

In the embodiment shown in Fig. 4a, the contact surface 21 of the pressure-receiving surface 11 of the multi-layered article 10 and the contact element 20 can be pressed against each other during translation close to each other, thereby allowing the contact element 20 to be a self-recovering object 10. The first end corner 11a of the pressed surface 11 is pressed against the second end angle 11d to complete the full surface contact of the pressed surface 11.

It should be noted that when the contact member 20 is a roller, the surface of the roller may be slightly elastically trapped when the laminated object 10 is touched, so that the contact wire 21 can also be presented in the form of a contact surface. The mutual contact pressure in the embodiment means that one of the multi-layer object 10 and the contact element 20 must apply a predetermined force (F) to generate a pressure on the pressure-receiving surface 11 when contacting each other (P). ).

In summary, in the embodiment, by the relative oblique arrangement and contact between the multi-layer object 10 and the contact element 20, the bonding bubbles generated between the bonding surfaces 101 and 102 and the adhesive 10c, respectively, can be controlled. The overflow direction and position allow the bonding bubble to completely overflow from the second end angle 11d, thereby effectively reducing the residual of the bonding bubble.

Further, according to the theorem of the force (F) = pressure (P) × force area (A), when the force (F) is maintained at a constant value, the area (A) at which the pressure surface 11 is momentarily stressed is larger. The smaller the pressure (P) is; on the contrary, the smaller the area (A) of the force is, the larger the pressure (P) is. In this embodiment, the force-receiving area (A) on the pressure-receiving surface 11 (such as the area opposite to the frame-shaped structure 10d) is maintained within a specific range during the entire pressure-fitting process without excessively large The change, so that when the force (F) maintains the constant output, the present embodiment easily obtains an appropriate pressure (P) and maintains the pressure (P) stable. It is also known that maintaining a proper and stable pressure (P) helps to reduce the chance of regenerating bubbles after the laminated object 10 is bonded.

Please refer to FIG. 4b for a detailed view of the bevel width of FIG. 4a for further illustrating the advantages of the present invention.

The contact member 20 is pressed against each other by the contact line 21 and the pressed surface 11 of the multi-layered article 10 during a relatively oblique translation, and a predetermined force (F) is applied by the position of the contact line 21 to act on the pressed surface. 11. Going further:

In the first stage of the touch-fitting process, the contact member 20 is the first end corner 11a of the contact pressure-receiving surface 11, forming a slope width w1 of the contact line 21 acting on the first end corner 11a; subsequently, at the touch pressure In the second stage of the bonding process, the contact element 20 is a first side edge region 11b that simultaneously touches the pressure surface 11 The two side edge regions 11c and the central region 11g respectively form a slope width w2 acting on the first side edge region 11b by the contact line 21, forming a slope width w3 acting on the second side edge region 11c by the contact line 21, and forming The bevel width w5 of the central portion 11g is applied by the contact line 21; finally, in the third stage of the touch-fitting process, the contact member 20 is the second end corner 11d of the contact pressure-receiving surface 11 (i.e., the first end angle 11a) Diagonally, a bevel width w4 is formed by the contact line 21 acting on the second end corner 11d, and after completion of the third stage, the contact element 20 is separated from the multi-layer object 10.

It can be seen that, in this embodiment, by the relative oblique arrangement of the multi-layer object 10 and the contact element 20, the contact element 20 is pressed by the first end corner 11a of the multi-layer object 10, and from the second end angle 11d. To complete the separation after the pressure is applied. Therefore, the entire pressure-fitting process of the present embodiment can effectively control the overflow direction and position of the bonding bubble, so that the bonding bubble is finally concentrated on one point (second end angle 11d) to overflow, and the residual of the bonding bubble is eliminated. .

Furthermore, since the first end angle 11a, the first side edge region 11b, the second side edge region 11c, and the second end corner angle 11d are positions corresponding to the frame-shaped structure 10d, when the pressure-receiving surface 11 is subjected to pressure, The regions of the first end corner 11a, the first side edge region 11b, the second side edge region 11c, and the second end corner 11d are subjected to a large reaction force, and the region of the central portion 11g is subjected to a small reaction force. Therefore, in the second stage of the touch-fitting process, when the first side edge region 11b, the central region 11g, and the second side edge region 11c are simultaneously pressed, the predetermined force (F) applied by the contact member 20 is mostly It is received by the first side edge region 11b and the second side edge region 11c. In this way, during the entire process of the pressure-contacting process of the pressure-receiving surface 11 of the multi-layered object 10, the pressing widths mainly received at each stage are sequentially the slope width w1, the slope width w2+w3, and the slope width w4. The change in width between the segments is obviously closer to a smaller range than the conventional touch-fit process (Fig. 1), thereby achieving the desired force-receiving area (A). This is because the multi-layer object 200 shown in FIG. 1 has a pressure-bearing surface of the first stage which is the entire side 211 area under the structure corresponding to the ink frame 220, and the pressure-receiving surface of the second stage has only two sides. The ends 213, 214, the pressure surface of the third stage is the entire area of the opposite side 212. Since the pressure surface of the multi-layer object 200 has a large change at different stages, the pressure at different positions also changes. Big. Thereby, in the whole pressure-fitting process, the embodiment is relatively easy to stably maintain the pressure (P) of the contact element 20 acting on the multi-layer object 10, so that the multi-layer object 10 allows the adhesive after the pressure bonding. During the drying process of 10c, it is less likely to generate regenerated bubbles.

Referring to FIG. 5a to FIG. 5c based on the architecture of FIG. 4a, a top plan view of different embodiments of the oblique arrangement of the contact element and the multi-layer object of the present invention is separately disclosed.

Figure 5a illustrates that the contact line 20 formed by the contact element 20 when the pressed surface 11 of the laminated article 10 is pressed is perpendicular to the pair of angles a1 of the pressed surface 11 of the multi-layered article 10. Wherein, the diagonal a1 of FIG. 5a is formed between the first end angle 11a and the second end angle 11d of the pressure receiving surface 11 of the multi-layer object 10, and the diagonal a1 is parallel to the opposite side path R2. The mutually parallel inclusions overlap.

Figure 5b illustrates the contact line 21 formed by the contact element 20 when it is pressed against the pressed surface 11 of the multi-layered article 10, parallel to a pair of angular lines a2 of the pressed surface 11 of the multi-layered article 10. Wherein, the diagonal a2 of FIG. 5b is formed between the third end angle 11e and the fourth end angle 11f of the multi-layer object 10, and the diagonal a2 is parallel to the adjacent side path R1, which are parallel to each other. overlapping.

Figure 5c illustrates that any diagonal a1, a2 on the stressed surface 11 of the lapped article 10 and the contact line 21 formed by the contact element 20 when the lapped article 10 is pressed are excluded from each other and are also excluded from each other. More specifically, any of the diagonals a1, a2 is distributed between the adjacent side path R1 and the opposite side path R2; or the first end angle 11a of the pressed surface 11 of the multi-layered object 10, The two end angles 11d, the third end angles 11e, and the fourth end angles 11f are each distributed among the four quadrants formed by the intersection of the adjacent side path R1 and the opposite side path R2.

In other words, any side 12 of the pressure-receiving surface 11 of the multi-layer object 10 carried by the platform 40 is formed by a contact line 21 formed when the contact element 20 touches the pressure-receiving surface 11 of the multi-layer object 10.
