That is, a touch panel body having a thickness of 0.2 to 4.0 mm, an external dimension of a rectangle having a side of 40 to 90 mm, and a material made of PET film or glass is prepared. This is positioned on the workbench. On the other hand, a film made of a PET film or a polarizing material having a thickness of 100 to 300 μm and an outer dimension substantially the same as the above is prepared as a bonding material. An adhesive film is formed on one surface of the bonding material, and a separate film is previously bonded to the entire surface of the adhesive film in order to prevent adhesion of dust and the like.
[0004]
Subsequently, after separating the separate film from the bonding material, the adhesive film of the bonding material is gradually approached from one side to the touch panel body positioned on the work table, and the touch panel body and the bonding material are overlapped. In parallel with this process, air (bubbles) remaining between the touch panel body and the bonding material was removed by pressing with a hand-held roller or the like.
[0005]
[Problems to be solved by the invention]
However, it is necessary for the operator to pay close attention to the work so that the bonding material does not slip laterally with respect to the touch panel body.

[0015]
DETAILED DESCRIPTION OF THE INVENTION
First, a method for laminating films using the film laminating apparatus according to the embodiment of the present invention will be described. Below, the code | symbol of A-I is attached | subjected in order of each process of the said bonding method. The film includes a thin film, a tape, a sheet, a chip, a thin plate or a thin panel.
[0016]
Moreover, in this Embodiment, although the touchscreen main body and the bonding material which were illustrated in the column of the prior art are applied as a film, the meaning of this invention is the material, shape, if it is bonding of films. Or it is not limited about a use etc. For example, a film electrode and a glass electrode of the touch panel body, a touch panel body and a support body made of a film (such as glass or polycarbonate as a material), or an adhesive tape having an adhesive layer formed on both sides and a touch panel body, etc. It can also be applied widely. The touch panel body is the main body of the touch panel as a product.
[0017]
A: As shown in FIG. 1, a slightly adhesive tape 2 is attached to the surface of an elastic thin plate 1 made of stainless steel or the like. The elastic thin plate 1 has an opening frame 3 for film setting. A slightly adhesive tape 2 is attached to the elastic thin plate 1 so as to close the film setting frame 3. At this time, as shown in the drawing, the entire area of the film set blank 3 may be covered with the fine adhesive tape 2, but the film set blank 3 and the fine adhesive tape 2 are shifted in the vertical and horizontal directions in the figure to form a slight gap. You may leave it.
[0018]
B: The elastic thin plate 1 is turned around the reversing shaft 4 fixed at one end with a screw or the like, and the front and back are reversed. As a result, as shown in FIG. 2, the slightly adhesive layer of the slightly adhesive tape 2 is exposed upward from the film setting blank 3 of the elastic thin plate 1 turned upside down. The other surface (lower surface in the figure) of the adhesive film 5 having an adhesive layer formed on one surface (upper surface in the figure) is attached to the exposed fine adhesive layer of the fine adhesive tape 2. That is, the adhesive layer of the adhesive film 5 and the separate film (not shown) that is covered to protect the adhesive layer 5 face upward.
[0019]
C: Said separate film is peeled off from the adhesive layer of the adhesive film 5. For example, the operator can hold a short stick coated with an adhesive on the tip, press it against the separate film, and then gradually move away from the sticking film 5, thereby separating the short film together with the short stick. May be peeled off from the adhesive film 5.
[0020]
D: In parallel with the above steps or separately, as shown in FIG. 3, the touch panel body 7 is positioned on the main frame 6 of the film sticking apparatus 10. That is, the underlying plate 60 attached on the main frame 6 is engraved with a panel set mold 8 which is a substantially rectangular shallow recess by milling or the like. The touch panel body 7 is inserted into the panel set form 8 with a scissors in a horizontal posture.
[0021]
E: The elastic thin plate 1 is turned in the direction opposite to the step A around the reversing shaft 4 and the front and back are reversed again. As a result, as shown in FIG. 4A, the adhesive layer of the adhesive film 5 that is turned over with the elastic thin plate 1 faces the touch panel body 7 in the panel set frame 8 with a gap. .
[0022]
In the above state, the height at which the bearing portion 40 supports the reversing shaft 4 is set to a position above the main frame 6 and in a range of 10 to 20 mm higher than the upper surface of the underlay plate 60. For this reason, the elastic thin plate 1 whose other end is received by the upper surface of the underlay plate 60 is in a posture that ascends and slopes in the forward movement direction of the rubber roller 9 indicated by an arrow X in FIG. That is, the distance between the adhesive layer of the adhesive film 5 attached to the elastic thin plate 1 and the touch panel body 7 gradually increases from the other end of the elastic thin plate 1 toward one end.
[0023]
Further, in this state, the dowel pins 20 protruding upward from the main frame 6 and penetrating through the pin holes 30 of the elastic thin plate 1 position the elastic thin plate 1 with respect to the underlying plate 60. The dowel pin 20 will be described later. In addition, the inclination angle is determined by the thickness dimension of the underlying plate 60. Therefore, if several underlay plates 60 having different thicknesses are prepared, a desired angle can be set for each product to be bonded.
[0024]
F: The rubber roller 9 is made of an elastic material such as silicon rubber, and waits in advance at the position shown in FIG. When the rubber roller 9 is sent out while rolling in the forward direction from this state, the elastic thin plate 1 is brought into close contact with the upper surface of the underlay plate 60 by the rubber roller 9 as shown in FIG. That is, the elastic thin plate 1 is a stainless steel (SUS304H) thin plate having a thickness of about 0.2 mm. For this reason, when the elastic thin plate 1 is pressed against the upper surface of the underlying plate 60 by the rubber roller 9, the elastic thin plate 1 is elastically deformed and bent, and temporarily becomes a straight shape along the upper surface of the underlying plate 60 or the touch panel body 7. The rubber roller 9 that reciprocates as described above passes between the two dowel pins 20 arranged corresponding to the pin holes 30 shown in FIG.
[0025]
As described above, in the process of elastic deformation of the elastic thin plate 1, the adhesive layer of the adhesive film 5 and the touch panel body 7 gradually come in close contact with each other from the left to the right in the drawing as the rubber roller 9 operates. , They will be pressed against each other. Thereby, the air between the adhesive film 5 and the touch panel body 7 is discharged to the right side in the figure while being compressed by the rubber roller 9. When the rubber roller 9 passes above the adhesive film 5 and the touch panel body 7, the adhesive film 5 and the touch panel body 7 are completely in close contact with each other. At the same time, the effect of eliminating all the air between the two can be achieved.
[0026]
Moreover, when the thickness of the sticking film 5 is thinner than the elastic thin plate 1, you may stick the backup member 11 slightly thicker than the elastic thin plate 1 on the surface of the slightly adhesive film 2, as shown in FIG. For the backup member 11, for example, a silicon rubber sheet of about 0.3 mm is applied. By interposing this between the rubber roller 9 (FIG. 4) and the slightly adhesive film 2, the pressing force of the rubber roller 9 is applied in the process in which the adhesive film 5 and the touch panel body 7 are pressed against each other as described above. It can be reliably transmitted to the film 5 and the touch panel body 7.
[0027]
G: While the rubber roller 9 is rolling in the direction opposite to the direction indicated by the arrow X in FIG. 4 (reverse movement direction), the rubber roller 9 is returned to the position shown in FIG. Here, as a position where the rubber roller 9 is made to stand by, the rubber roller 9 may be moved away from the elastic thin plate 1 so that the rubber roller 9 does not contact the other end of the elastic thin plate 1.
[0028]
H: When the rubber roller 9 is returned to the standby position, the elastic thin plate 1 immediately returns to the inclined state shown in FIG. The restored elastic thin plate 1 is rotated again around the reversing shaft 4 and the front and back are reversed. Thereby, the elastic thin plate 1 will be in the state shown in FIG. 2 again.
[0029]
I: If the film 5 and the touch panel body 7 bonded together as described above are removed from the panel setting blank 3, the above-described series of steps is completed. At this time, since the adhesive force of the adhesive film 5 and the touch panel body 7 is stronger than the adhesive force of the slightly adhesive tape 2 and the adhesive film 5, the adhesive film 5 is peeled from the slightly adhesive tape 2. However, the state of being in close contact with the touch panel body 7 is maintained.
[0030]
In addition, even if the adhesion and peeling of the adhesive film 5 are repeated, the slightly adhesive layer of the slightly adhesive tape 2 does not deteriorate significantly. For this reason, once the process A is performed, the process is omitted for about 100 cycles, and the processes B to I are repeated.
[0031]
The adhesive layer or the slightly adhesive layer described above is not necessarily formed on the entire surface of the adhesive film 5 or the slightly adhesive tape 2. The pressure-sensitive adhesive layer or the slightly pressure-sensitive adhesive layer may be formed by applying a pressure-sensitive adhesive so as to have a plurality of spots or lines. In addition, the adhesive force of the adhesive layer or the slightly adhesive layer may be adjusted by adjusting the components of the adhesive, but by changing the density of the adhesive applied in a spot shape or linear shape as described above. Also good.
[0032]
Next, the film sticking apparatus 10 which concerns on embodiment of this invention is demonstrated. FIG. 3A shows a plan view of the main frame 6, the underlay plate 60, the bottom raising plate 61, and the bearing portion 40 that constitute the main part of the film sticking apparatus 10. The side view is shown in FIG.
[0033]
The bottom raising plate 61 supports the inverted elastic thin plate 1 in a horizontal posture so that the operation of attaching the adhesive film 5 to the slightly adhesive layer of the slightly adhesive tape 2 can be stably performed in the above-described step B. . As shown in FIG. 6, the main frame 6 is provided with a pressure means 12 for pressing the rubber roller 9 against the underlying plate 60, a drive means 19 for reciprocating the rubber roller 9, and a control means (not shown) for controlling them. ing.
[0034]
The bearing portion 40 is configured to support the reversing shaft 4 fixed to the elastic thin plate 1 in a swingable (loose) manner in the steps A and E described above. The reason for bearing in this way is as follows. That is, in the above-described process F, when the rubber roller 9 moves in the forward movement direction, the elastic thin plate 1 is gradually elastically deformed and pressed against the upper surface of the underlying plate 60. As a result, the entire elastic thin plate 1 is lowered. The elastic thin plate 1 is restricted from moving in the horizontal direction by a dowel pin 20 (FIG. 4). For this reason, a mechanism that allows the elastic thin plate 1 to swing as the rubber roller 9 moves is indispensable.
[0035]
Specifically, the bearing portion 40 forms a longitudinal groove 41 wider than the shaft diameter of the reversing shaft 4, and the reversing shaft 4 is inserted into the longitudinal groove 41 together with a bearing (not shown) made of synthetic resin. Further, a coil spring 41 c that biases the bearing upward is loaded in the vertical groove 41. With this configuration, when the entire elastic thin plate 1 is lowered by the pressing force of the rubber roller 9, the reversing shaft 4 can also be lowered against the urging force of the coil spring 41c.
[0036]
A bridge piece 42 is fixed to the upper end portion of the bearing portion 40 with screws 43. When the screw 43 is loosened and the bridge piece 42 is removed, the longitudinal groove 41 is opened, and the reversing shaft 4 can be extracted together with the bearing. This considers the convenience at the time of replacing | exchanging the elastic thin plate 1 for another specification according to the dimension and external shape of the film bonded using the said film sticking apparatus 10. FIG.
[0037]
When the reversing shaft 4 of the elastic thin plate 1 is attached to the bearing portion 40, first, the reversing shaft 4 is inserted into the longitudinal groove 41 together with the bearing, and then the screw 43 is loosened, as shown in FIG. The dowel pin 20 is passed through the pin hole 30 drilled in 1 as shown in FIG. Subsequently, the screw 43 is tightened to fix the bridge piece 42. By performing such setting, every time the elastic thin plate 1 is repeatedly inverted, the dowel pin 20 penetrates the pin hole 30 and the elastic thin plate 1 is positioned. Even when the reversing shaft 4 is detached from the bearing portion 40 and attached to the bearing portion 40 again, adjustment adjustment of the bearing portion 40 and the elastic thin plate 1 is not necessary, so only the operation of attaching the reversing shaft 4 to the bearing portion 40 is required. Thus, the elastic thin plate 1 can be attached and detached. A screw may be applied to the screw 43 so that it can be turned manually without using a spanner or the like.
[0038]
The pressurizing means 12 is provided with brackets 91 for supporting both ends of the support shaft 90 of the rubber roller 9 on both side portions of the main frame 6, and the support rod of the rubber roller 9 by the operation rod 14 of the air cylinder 13 provided at the upper end of the bracket 91. 90 is pressed downward (underlay plate 60). Both ends of the support shaft 90 are inserted into the elongated holes 15 that open in the bracket 91 and extend in the vertical direction. A rubber roller 9 is rotatably attached around the support shaft 90. Since the support shaft 90 itself does not rotate, the actuating rod 14 directly presses the support shaft 90 with the synthetic resin cushioning material 16 provided at the tip thereof. This pressure is 1-16kg / cm ² It is preferable to set to.
[0039]
Instead of the air cylinder 13, a mechanism that urges the support shaft 90 downward by a coil spring or the like may be employed. However, as described above, by applying the air cylinder 13 as the pressurizing source of the pressurizing means 12. The following advantages are obtained. That is, the load applied to the rubber roller 9 can be easily increased or decreased simply by operating the pressure reducing valve or the like. In addition, the load applied to the rubber roller 9 can be kept constant without being affected by the stroke of the operating rod 14. For this reason, even if the diameter of the operating roller 14 is changed by changing the diameter of the rubber roller 9 or changing the thickness of the underlying plate 60, the air pressure supplied to the air cylinder 13 is changed. No need to adjust frequently.
[0040]
The driving means 19 is fixed to both sides of the main frame 6 in a horizontal posture parallel to the operating rod 17 and an air cylinder 18 having an operating rod 17 that advances and retreats the bracket 91 in the direction in which the rubber roller 9 reciprocates (left and right in the figure). And a guide rail (not shown) that slidably engages the bracket 91.
[0041]
The reaction force that the air cylinder 13 presses the rubber roller 9 is received by the guide rail. For this reason, the actuating rod 17 receives only a compression or tensile load in its advancing / retreating direction. The rubber roller 9 preferably travels at a low speed in the range of 0.3 to 2.0 cm / sec and moves backward at the highest speed of the air cylinder 18. Setting or changing the traveling speed can be easily performed only by increasing or decreasing the opening degree of the adjusting valve provided in the air cylinder 13.
[0042]
As a drive source of the drive means 19, a cam mechanism or a crank mechanism may be applied instead of the air cylinder 18. Alternatively, such a drive source may be omitted, and the rubber roller 9 may be manually reciprocated together with the bracket 91. The above-mentioned control means is a technique for controlling the operation of a valve that is responsible for blocking or switching the compressed air supplied to the air cylinders 13 and 18. Since this is a self-evident technique such as a sequence circuit using a known relay or sensor, a description thereof will be omitted.
[0043]
As shown in FIG. 7, the underlay plate 60 includes an upper surface material 63 in which the panel setting mold 8 and the pin insertion holes 62 are formed, and a lower surface material 65 in which the dowel pins 20 protrude upward and the pin insertion holes 64 are formed. Is a double structure. The upper surface member 63 is slidable with respect to the lower surface material 65 within a range corresponding to the gap between the pin insertion hole 62 and the dowel pin 20 and can be adjusted in position.
[0044]
The lower surface member 65 is positioned with respect to the main frame 6 by inserting dowel pins 66 provided on the upper surface of the main frame 6 into the pin insertion holes 64. That is, the lower surface member 65 is directly positioned on the main frame 6 by the dowel pins 66, and the dowel pins 20 are also positioned with respect to the main frame 6.
[0045]
On the other hand, the upper surface member 63 has the adhesive film 5 set on each of the elastic thin plate 1 and the upper surface member 63 in a state where the dowel pin 20 is passed through the pin hole 30 of the elastic thin plate 1 as shown in FIG. It is set so that the position of the touch panel body 7 is determined. In order to maintain such a positional relationship, the upper surface material 63 and the lower surface material 65 are adjusted in position within a range corresponding to the gap and fixed to each other with screws or the like. Therefore, the upper surface material 63 and the lower surface material 65 can be handled as an integral jig, and the adjustment for positioning the dowel pin 20 with respect to the main frame 6 is performed again even if the attachment and detachment from the main frame 6 is repeated. There is no need.
[0046]
As described above, the underlay plate 60 is fastened on the main frame 6 while being positioned by the dowel pins 66. The underlay plate 60 is fixed by simple fastening means such as screws for fixing the underlay plate 60 to the main frame 6. Alternatively, the fastening means may be omitted. For this reason, as described above, when the elastic thin plate 1 is replaced with another one, the underlay plate 60 can be easily replaced together.
[0047]
Furthermore, as shown in FIG. 8, film positioning pins 67 may protrude upward on the upper surface of the bottom raising plate 61. Specifically, the outer size of the separate film 50 that has been attached in advance to the adhesive layer of the adhesive film 5 is set to be larger than that of the adhesive film 5. Pin insertion holes 51 are formed on both sides of the separate film 50 extending outward from the adhesive film 5. Correspondingly, a pin insertion hole 68 is also formed in the elastic thin plate 1. And in said process B, each pin of the separate film 50 and the elastic thin plate 1 is just before or simultaneously with the operation | work which affixes the adhesion film 5 on the fine adhesion layer of the fine adhesion tape 2 affixed on the surface of the elastic thin plate 1. The film positioning pins 67 are inserted into the insertion holes 51 and 68.
[0048]
Thereby, the sticking film 5 is positioned with respect to the elastic thin plate 1 and further with respect to the frame 3 for film set. Such a configuration is such that the outer size of the adhesive film 5 is smaller than the opening dimension of the film-set blank 3 and the adhesive film is placed at a predetermined position inside the opening edge of the film-set blank 3. This is useful when 5 needs to be placed accurately.
[0049]
In cases other than the above, that is, when the shape size of the sticking film 5 is substantially the same as the opening size of the film setting blank 3, or along the side of the opening edge of the film setting punch 3. In the state where the adhesive film 5 is attached to the slightly adhesive layer of the slightly adhesive tape 2, it is possible to remove the film set by aligning one side of the adhesive film 5 with the opening edge of the film setting punch frame 3. The adhesive film 5 can be easily positioned with respect to the frame 3.
[0050]
Although not shown, the bottom-up plate 61 may be detachably attached to the main frame 6 in a state where the bottom-up plate 61 is positioned by a pin, similarly to the underlying plate 60.
[0051]
Further, the film setting blanks 3 may be formed at a plurality of locations on the elastic thin plate 1. In this case, if the panel set form 8 is additionally formed on the underlay plate 60 corresponding to the plurality of film set blanks 3, a plurality of adhesive films 5 can be obtained by reciprocating the rubber roller 9 once. A plurality of touch panel bodies 7 can be bonded together.
[0052]
The main members such as the main frame 6, the underlay plate 60, the bottom raising plate 61, and the bearing portion 40 do not need to be limited in manufacturing method or material, but may be formed by machining an aluminum plate material, for example. This is preferable in terms of reducing the weight of the entire apparatus. In this case, even if the film to be bonded is glassy, it is desirable to subject the surface of the main member to hard alumite treatment so that the main member is not damaged by contact with the film.
[0053]
Although the embodiment of the present invention described above has been described with reference to the drawings, the present invention is not limited to the illustrated embodiment. Further, in this description, the description of the top and bottom, left and right, one end, the other end, the front surface or the back surface of the drawing is a relative index determined for convenience, and the orientation when using the film sticking device according to the present invention The posture is not substantially limited.
[0054]
In addition, the technical scope of the present invention includes embodiments in which various improvements, modifications or changes are made based on the knowledge of those skilled in the art without departing from the spirit of the present invention. Moreover, you may implement in embodiment which substituted the invention specific matter which comprises this invention with the other technique within the range with the effect | action or effect of this invention.
[0055]
For example, the elastic thin plate 1 may be mainly composed of a highly elastic synthetic resin plate, or raw rubber, urethane foam, or the like may be employed as the material of the rubber roller 9. Alternatively, when the pressure-sensitive adhesive constituting the pressure-sensitive adhesive layer is heat-meltable or exhibits a good pressure-sensitive adhesive action at a predetermined temperature, a heater or the like is provided around the elastic thin plate 1, the rubber roller 9, the main frame 6, or the periphery thereof. You may make it add.
[0056]
【The invention's effect】
According to the film laminating apparatus and the method according to the present invention, since the adherent film is faced to the adhesive film in an inclined posture, and the films are gradually pressed by a roller that travels between the films, the films Air in which air remains as air bubbles can be completely discharged in the process in which the films are in close contact with each other.
[0057]
Further, since the removable and peelable fine adhesive tape is attached to the elastic thin plate and the adhesive film is attached to the fine adhesive tape, the adhesive film can be immediately set on the elastic thin plate. That is, it is possible to save a series of troubles such as positioning the adhesive film with respect to the elastic thin plate and holding it by an operator. Moreover, positioning can be easily performed by fitting each film into a punched frame or a mold, and each film is not displaced after positioning.
[0058]
Therefore, the operator does not pay close attention so that the adhered film does not shift laterally with respect to the adhered film. In addition, since the roller is pressed against the overlapped film by the pressing means and the roller is driven by the driving means, most of the laminating work can be automated. For this reason, it is possible to greatly reduce the work time and to prevent the occurrence of defective products due to unfamiliarity of the operator.
[0059]
Further, in the process of running the roller, as described above, the adherent film is faced in an inclined posture and pressed by a roller running in a predetermined direction so that air is excluded from between the two. Therefore, the adherent film can be neatly attached to the adherent film without leaving bubbles or the like. Moreover, since the finished product can be easily and reliably achieved by mechanical operation, a uniform product can fail or fail regardless of the operator's familiarity and work proficiency as in the past. Can be produced in large quantities at low cost.
