Description

Thin piece peeling device and peeling method

The present invention relates to a peeling apparatus and a peeling method, and more particularly to a peeling apparatus and a peeling method for peeling a thin piece from an object.

In the process of directly bonding the touch display device, the touch panel is adhered to the display panel by adhesive. When the touch panel and the display panel are separated after heavy work or maintenance, the metal wire is cut into the adhesive layer. The glue layer is configured to separate the touch panel from the display panel, thereby completing the operation of peeling off the touch panel from the touch display device.

Although the adhesive layer has fluidity, its viscosity is quite large. In addition to sticking to the metal wire, the metal wire will be subjected to excessive force during cutting, and will be permanently deformed and severely broken. In order to reduce the force of the metal wire, a peeling method is proposed in which the metal wire is pulled perpendicularly to the cutting direction when cutting, which can reduce the adhesion of the adhesive to the metal wire, but it is easy to make the adhesive layer gather into the block. In addition to the problem of the above permanent deformation and fracture, the touch panel and the display panel may be damaged. In addition, a stripping method for heating the metal wire is proposed, which can greatly reduce the viscosity of the adhesive layer, but when the temperature is too low, the viscosity is not reduced enough; when the temperature is too high, the metal wire is emitted. Heat can also cause damage to other components. In addition, when the size of the touch display device to be peeled off becomes larger, the area to be cut is larger, and the aforementioned problem will be more serious.

In view of the problems in the prior art, one of the objects of the present invention is to provide a peeling device for peeling a thin piece from an object, which, when cut, uses a cutting line to produce a relative deflection with the object to be peeled off to reduce the cutting line. The force can also greatly reduce the degree of aggregation of the glue.

The stripping apparatus of the present invention comprises a stage, a cutting line and two holding elements. The stage is used to secure an object and deflect back and forth relative to a peeling direction. The cutting line is located above the stage for cutting into the article substantially along the stripping direction to peel a thin piece from the article. The holding elements are oppositely disposed on two sides of the stage, and two ends of the cutting line are respectively clamped on the two holding elements, and the two holding elements can be individually moved along the peeling direction to make the cutting line relative to the peeling The direction is deflected back and forth. Wherein the stage and the cutting line move relatively parallel to the peeling direction, and the deflection direction of the stage is opposite to the deflection direction of the cutting line. Thereby, the stripping device utilizes the cutting line to deflect relative to the object to peel off the thin piece, and reduce the force of the cutting line, prolong the service life of the cutting line and inhibit the degree of aggregation of the glue.

Another object of the present invention is to provide a peeling method which utilizes the stripping apparatus of the present invention to peel a thin piece from an object, and when the peeling is performed, the force of the cutting line is reduced, and the degree of aggregation of the adhesive can be greatly reduced, so that The thin piece can be peeled off safely.

The stripping method of the present invention comprises cutting the cutting line between the object and the thin member from one side of the object fixed to the stage, and alternately moving the two holding members relative to the peeling direction while simultaneously The movement of the stage corresponding to the two holding elements is deflected back and forth with respect to the peeling direction. Thereby, the peeling method can reduce the force of the cutting line and suppress the aggregation of the adhesive by the peeling device, so that the thin piece can be peeled off safely.

In short, the stripping device and the stripping method of the present invention use a cutting line and a relative deflection of the object to peel off the thin piece from the object during cutting, thereby reducing the force of the cutting line and greatly reducing the degree of aggregation of the glue. The problem of the prior art that the cutting line is easy to break, the glue is easy to aggregate, and thus other components are damaged.

The advantages and spirit of the present invention will be further understood from the following detailed description of the invention.

Please refer to FIG. 1, which is a top plan view of a stripping apparatus 1 in accordance with a preferred embodiment of the present invention. The stripping apparatus 1 can include a frame 12, a stage 14, a cutting line 16, two holding elements 18, 19, two slide rails 20, and a control device 22. The stage 14 can be disposed on the frame 12 for fixing an object 2, and the stage 14 can be deflected back and forth with respect to a peeling direction 15 (indicated by an arrow) by means of a rotating shaft 142 (indicated by a broken line). The slide rail 20 can be fixed to the frame body 12 and extends in the peeling direction 15. The holding members 18 and 19 are oppositely disposed on both sides of the stage 14 and respectively slid on the slide rail 20 so as to be movable in the peeling direction 15. The cutting line 16 is located above the stage and its ends are clamped to the holding elements 18, 19, respectively. The gripping elements 18, 19 can be individually moved in the peeling direction 15 to deflect the cutting line 16 back and forth relative to the peeling direction 15. Two sensors 202, such as a photo sensor or a limit switch, may be provided on the slide rail 20 as a range for limiting the movement of the gripping members 18, 19. The control device 22 can be disposed on the frame 12 and electrically connected to the stage 14, the holding elements 18, 19, and the sensor 202 to control the deflection of the stage 14 and the movement of the holding elements 18, 19, and the user can control The operating interface provided by device 22 is parameterized.

During the stripping operation, the cutting line 16 forms an acute angle 162 with one of the side edges 24 of the article 2 to cut into the article 2 substantially in the peeling direction 15; then the stage 14 and the cutting line 16 move relatively parallel to the peeling direction 15 And the deflection direction of the stage 14 is opposite to the deflection direction of the cutting line 16 so that the cutting line 16 can be peeled off from the object 2 by a thin piece. For example, when the deflection direction of the stage 14 is clockwise, the deflection direction of the cutting line 16 is counterclockwise, and when the deflection direction of the stage 14 is counterclockwise, the deflection direction of the cutting line 16 is clockwise. In this embodiment, the object 2 is a display panel, and the thin member is a touch panel attached to the display panel, but the invention is not limited thereto. For example, other embodiments in which a film member is attached to a substrate also apply to the concept of the present invention.

Please refer to FIG. 2, which is a flow chart of a stripping method in accordance with a preferred embodiment of the present invention. The peeling method is for peeling off the thin member from the article 2 by the aforementioned peeling device 1. The stripping method mainly comprises the step S110 of cutting the cutting line 16 from the side 24 of the article 2 fixed on the stage 14 between the object 2 and the thin member; and the step S120 alternately making the holding members 18, 19 relative to the peeling direction 15 moves while simultaneously deflecting the movement of the carriage 14 corresponding to the gripping elements 18, 19 relative to the stripping direction 15. Before the step S110, the stripping method fixes the object 2 on the stage 14, and sets relevant operating parameters, as shown in step S100. The step S110 of the stripping method then displaces the holding elements 18, 19 in the peeling direction 15 such that a portion 164 of the cutting line 16 contacts the side 24 of the object 2 and forms an acute angle 162 with the side 24, as shown in step S112; The schematic of the stripping apparatus 1 after the completion of the step is as shown in Fig. 1. The acute angle 162 for cutting the object 2 can be set at 15 degrees to 25 degrees, but the invention is not limited thereto.

The step S110 of the stripping method then fixes the gripping element 18 proximate the portion 164 of the cutting line 16 and moves the other gripping element 19 in the peeling direction 15 such that the cutting line 16 cuts into the article 2 from the side 24 and the thin piece For example, as shown in step S114; the schematic diagram of the stripping device 1 after the step is completed is as shown in FIG. In addition, in FIG. 3, the initial position P1 and the horizontal position P2 of the holding member 19 are indicated by broken lines, and the stage 14 and the upper object 2 thereof are also indicated by broken lines before the stage 14 is deflected, and the object 2 has been The area where the cutting line 16 is peeled off is indicated by hatching. When the holding member 19 moves from the horizontal position P2 to the position P3 after the completion of the step, the stage 14 is synchronously deflected counterclockwise; this allows the cutting line 16 to be swept over a larger area than when the stage 14 is not deflected, and the peeling can be accelerated. speed. In addition, the deflection angle of the aforementioned stage 14 can be set to 15 degrees; however, the invention is not limited thereto. Incidentally, in the third figure, a portion of the stripped area is located below the cutting line 16, which is caused by the deflection of the stage 14; the same is also the case in the subsequent figures, and will not be described again.

The step S120 of the stripping method then fixes the gripping member 19 to move the gripping member 18 a predetermined distance D in the peeling direction 15 such that the cutting line 16 is deflected in a first rotational direction 172 (i.e., counterclockwise) and is held in the gripping member 18. When moving, the stage 14 is simultaneously deflected (ie, clockwise deflected) in a second rotational direction 174 opposite to the first rotational direction 172. As shown in step S122, the schematic of the stripping apparatus 1 after the step is completed is as shown in FIG. Show. In addition, in FIG. 4, the initial position P4 and the horizontal position P5 of the holding member 18 are indicated by broken lines, and the stage 14 and its upper object 2 are also indicated by broken lines before the stage 14 is deflected in the second rotational direction 174. The area of the article 2 that has been peeled off by the cutting line 16 is indicated by hatching. When the holding member 18 is moved from the initial position P4 to the horizontal position P5, the stage 14 is also deflected to the horizontal position (refer to the position of the stage 14 shown in Fig. 1), at which time the stage 14 has been deflected by 15 degrees; When the holding member 18 is moved from the horizontal position P5 to the position P6 after the completion of the step, the stage 14 is continuously synchronized and deflected in the second rotational direction 174. Similarly, this allows the cutting line 16 to sweep over a larger area than when the stage 14 is not deflected, thereby speeding up the stripping speed. In addition, the deflection angle of the stage 14 in the second rotation direction 174 can be set to 30 degrees, that is, after the stage 14 is rotated to the horizontal position, and then rotated 15 degrees, the present invention is not limited thereto.

The step S120 of the stripping method then fixes the gripping member 18 such that the gripping member 19 is also moved a predetermined distance D in the peeling direction 15 such that the cutting line 16 is deflected in the second rotational direction 174, and when the gripping member 19 is moved, the carrier 14 is caused to move. The first rotation direction 172 is deflected. As shown in step S124, the schematic diagram of the stripping apparatus 1 after the step is completed is as shown in FIG. In addition, in FIG. 5, the initial position P3 and the horizontal position P7 of the holding member 19 are indicated by broken lines, and the stage 14 and its upper object 2 are also indicated by broken lines before the stage 14 is deflected in the first rotational direction 172. The area of the article 2 that has been peeled off by the cutting line 16 is indicated by hatching. When the holding member 19 is moved from the initial position P3 to the horizontal position P7, the stage 14 is also deflected to the horizontal position (refer to the position of the stage 14 shown in Fig. 1), at which time the stage 14 has been deflected by 15 degrees; When the gripping member 19 is moved from the horizontal position P7 to the position P8 after the completion of the step, the stage 14 is continuously synchronized and deflected in the first rotational direction 172. As such, this allows the cutting line 16 to be swept over a larger area than when the stage 14 is undeflected, which accelerates the peeling speed. Further, the deflection angle of the stage 14 in the first rotational direction 172 is also set to 30 degrees, that is, after the stage 14 is rotated to the horizontal level, the rotation of the stage 14 is continued by 15 degrees.

The step S120 of the stripping method next determines whether the peeling operation has been completed, as shown in step S126. In step S126, if the determination is completed, the peeling operation is ended, and other work procedures such as immersion, washing, etc. may be performed on the peeled object; if the determination is not completed, steps S122 and S124 are repeated. The determining step S126 can be performed once between step S122 and step S124, which may reduce the execution of step S124 once.

It is to be noted that the distance (ie, the predetermined distance) at which the holding members 18 and 19 are alternately moved is not specified in the foregoing embodiment. In practice, it may depend on the characteristics of the object to be processed 2, especially the adhesive layer. Characteristics. Moreover, although the deflection angle of the stage 14 in the alternate movement of the holding elements 18 and 19 is 30 degrees (which can be regarded as plus or minus 15 degrees with respect to the peeling direction 15), the present invention is not limited thereto, for example, the characteristics of the object to be processed 2 can be seen. Depending on the characteristics of the adhesive layer. In addition, during the stripping process, there may be a need to change the peeling parameters to improve the peeling efficiency due to the condition of the adhesive layer or the variation of the characteristics of the cutting line 16 itself. Therefore, the stripping method of the present invention can also include a sensing module 182, 192 by the holding elements 18, 19 of the stripping device 1 for measuring the stress in the cutting line 16 to dynamically change the peeling parameters. For example, in step S122, when the holding member 18 moves, the stress of the cutting line 16 is measured to dynamically adjust the moving speed of the holding member 18; likewise, in step S124, when the holding member 19 moves, the cutting line is measured. The stress of 16 dynamically adjusts the moving speed of the gripping member 19. Since the stage 14 is coupled to the movement deflection of the holding members 18, 19, the rotational angular velocity is also dynamically adjusted. Although the speed of the movement of the holding elements 18 and 19 is increased as an example, the predetermined distance D may be lengthened within the range of the allowable stress of the cutting line 16, or both, and the present invention does not limit. Thereby, the peeling method dynamically adjusts the peeling operation parameter in accordance with the actual peeling condition to increase the peeling work speed. The sensing module 182, 192 can be a tension meter or a torque meter, and the invention is not limited thereto.

In the foregoing embodiment, the stage 14 of the stripping apparatus 1 uses only a single rotating shaft 142 for the purpose of deflecting the stage 14, but the invention is not limited thereto. Please refer to FIG. 6, which is a schematic diagram of a stage 34 in accordance with another embodiment of the present invention. In this embodiment, the stage 34 is formed with two arcuate guide grooves 342 and 344. The stage 34 includes a first rotating shaft 346 and a second rotating shaft 348, and is sequentially disposed in the arc in the peeling direction 15 . In the shaped guide grooves 342, 344. By controlling the rotation of the first rotating shaft 346 and the second rotating shaft 348 in the arcuate guiding grooves 342, 344, the movement of the stage 34 relative to the peeling direction 15 can be realized, so that the stage 34 can also replace the foregoing. Stage 14. In practice, the first rotating shaft 346 and the second rotating shaft 348 are realized by meshing with the curved guiding grooves 342 and 344, but the invention is not limited thereto.

Please refer to FIGS. 7 and 8 for a deflection diagram of the stage 34 at a different relative position to the cutting line 16; wherein the object 2, the cutting line 16, and the holding elements 18, 19 are indicated by dashed lines. The article 2 defines a peel length 26 substantially along the peeling direction 15, i.e. the length of the article 2 in the peeling direction 15. When the cutting line 16 travels in the peeling direction 15 by less than one half of the peeling length 26, that is, the center point of the cutting line 16 is still in the upper half of the object 2, the first rotating shaft 346 is controlled to rotate, and the second rotating shaft 348 is fixed. That is, the stage 34 can be deflected with respect to the peeling direction 15 with the second rotating shaft 348 as the center of rotation, as shown in FIG. 7; when the cutting line 16 travels in the peeling direction 15 by more than one half of the peeling length 26, That is, the center point of the cutting line 16 is already in the lower half of the object 2, and the second rotating shaft 348 is controlled to rotate, and the first rotating shaft 346 is fixed, that is, the stage 34 can be rotated with the first rotating shaft 346 as a center of rotation. Direction 15 is deflected back and forth as shown in Figure 8. The rotation centers of the stage 34 are changed by the two rotating shafts 346 and 348. This allows the cutting line 16 to be peeled off in each peeling period (that is, in the steps S122 and S124), that is, the peeling speed can be accelerated.

In addition, the rotation of the first rotating shaft 346 and the second rotating shaft 348 can be controlled at the same time to enable the stage 34 to rotate at different centers of rotation according to the relative positions of the cutting lines 16 so that the cutting line 16 The area peeled off during each stripping cycle is more similar, making the stripping operation more efficient.

In the foregoing embodiment, the relative movement of the stages 14, 34 and the cutting line 16 is mainly achieved by moving the holding members 18, 19, but the invention is not limited thereto. Please refer to FIG. 9, which is a top plan view of a stripping device 5 in accordance with another preferred embodiment of the present invention. The stripping device 5 is substantially identical in structure to the stripping device 1, except that the stripping device 5 is configured to move the stage 14 to effect relative movement of the stage 14 and the cutting line 16. Further, the stripping device 5 includes a linear moving device 52 that can be disposed on the frame 12, and the stage 14 is coupled to the linear moving device 52, whereby the linear moving device 52 can be utilized to cause the stage 14 to be opposite to Move in the direction of the peeling direction 15. The linear moving device 52 can be implemented by using a lead screw, a rack or a crawler, but the invention is not limited thereto; and the rotating shaft 142 of the stage 14 is coupled to the linear moving device 52 by a base 144, so the stage 14 still has to be deflected back and forth with respect to the peeling direction 15 by the axis of rotation 142.

Since the peeling device 5 is moved by the stage 14 with respect to the frame 12, the holding members 18 and 19 can be reciprocatingly moved to realize the peeling operation. Further, taking FIG. 9 as an example, when the stage 14 moves in a direction opposite to the peeling direction 15 (ie, upward), the holding member 18 also moves upward from the initial position P11, and the holding member 19 is moved from the initial position P21. Moving downward, the cutting line 16 is formed to rotate in the second rotational direction 174; at this time, the stage 14 is also rotated by the rotating shaft 142 in the first rotational direction 172. When the holding member 18 reaches the end position P13 and the holding member 19 reaches the end position P23, the holding member 18 and the holding member 19 are stopped, that is, the peeling operation of this step is completed. Then proceed to the next step of the stripping operation, as shown in Figure 10. When the stage 14 continues to move upward again, the holding member 18 moves downward from the initial position P13 (ie, the end position P13 of the previous step), and the holding member 19 moves upward from the initial position P23 (ie, the end position P23 of the previous step). The cutting line 16 is formed to rotate in the first rotational direction 172; at this time, the stage 14 is also rotated by the rotating shaft 142 in the second rotational direction 174. When the holding member 18 reaches the end position P11 and the holding member 19 reaches the end position P21, the holding member 18 and the holding member 19 are stopped, that is, the peeling operation of this step is completed. Then continue to repeat the above two steps until the peeling is completed. Thereby, the peeling device 5 can also produce and peel off the object 2 The same peeling effect of the equipment 1 operation.

It is to be noted that in the peeling operation of the peeling device 5, the holding member 18 and the holding member 19 are reciprocatingly cycled around the horizontal positions P12 and P22, respectively, but the invention is not limited thereto. For example, after each reciprocating motion, the holding member 18 and the holding member 19 can be adjusted relative to the stage 14 at horizontal positions P12 and P22, respectively, which can shorten the distance that the linear moving device 52 drives the stage 14 to move. Further, in the peeling device 5, when the holding member 18 or the holding member 19 moves in the same direction as the stage 14, when the moving speed of the holding member 18 or the holding member 19 and the stage 14 are the same, the peeling device 5 can be obtained The peeling effect of the peeling device 1 is equivalent.

Please refer to Fig. 11, which is a top plan view of a stripping device 7 in accordance with yet another preferred embodiment of the present invention. The peeling device 7 has substantially the same structure as the peeling device 5, except that the holding member 18 and the holding member 19 of the peeling device 7 are similar to the holding member 18 and the holding member 19 of the peeling device 1, and continue to move in the peeling direction 15, and The stage 14 of the stripping device 7 is similar to the stage 14 of the stripping apparatus 5, and is continuously moved in the opposite direction to the peeling direction 15, so that the relative movement of the cutting line 16 and the stage 14 can be generated, thereby enabling the peeling of the object 2. operation. Since the structures of the stripping devices 1, 5, and 7 are substantially the same, in practice, the operation of each of the stripping devices 1, 5, and 7 described above can be realized by a single physical device. In addition, when the linear moving device 52 itself is rotatable relative to the frame 12, the deflection of the stage 14 is also directly caused by the rotation of the linear moving device 52 to deflect the stage 14 relative to the peeling direction 15. The table 14 can have a deflection function without rotating the shaft 142, and its operation diagram is as shown in Fig. 12. Shown.

As described above, the present invention utilizes the stage to move relative to the cutting line and the stage and the cutting line are deflected opposite each other to effect the object peeling operation. At each deflection peeling, not all of the cutting lines are cut at the same distance, or the area where each part of the cutting line is peeled off is not the same. In principle, each time the deflection is peeled off, the holding member is moved relatively close to the stage. The area where part of the cutting line is peeled off is large; in the macro view, the center of the cutting line is demarcated, and each deflection peeling can be regarded as mainly performing peeling operation by half of the cutting lines, so that the overall force of the cutting line is reduced, The utility model can not only prolong the service life of the cutting line, but also increase the stability of the cutting line during cutting, and effectively solve the problem that the cutting line is easy to break in the prior art. In addition, the cutting line of the present invention travels substantially in the peeling direction, and does not pull left and right when cutting (ie, the cutting line moves along the axial direction thereof), so that the aggregation of the glue can be effectively suppressed, and the adhesive in the prior art is prevented from being easily gathered. The problem of damage to other components.

The above are only the preferred embodiments of the present invention, and all changes and modifications made to the scope of the present invention should be within the scope of the present invention.
