Description

  The present invention relates to a mechanism that stably peels off a sticking member attached to the sticking member with the same tip from the sticking member and a peeling method thereof.

  For example, there is a polarizing plate of a liquid crystal display as a component that requires peeling of the sticking member. In the production of a polarizing plate, before the step of attaching the polarizing plate, there is a step of peeling off the protective film attached to the polarizing plate with the same tip. Depending on the polishing direction of the end face polishing machine, the polarizing plate has a rounded corner on the polishing end face of the protective film, so that it is difficult to make a “peeling trigger”, that is, the tip of the sticking member peeled off from the member to be stuck. . For example, in the case of a peeling method in which the tape is attached to the tip of the protective film and pulled up, the protective film does not attach to the tape because the peeling force acts in a wide range and the tip of the protective film is not attached to the tape. Cases arise. Since the peeling operation is unstable, it is difficult to automate, and even in the case of manual work, it is necessary to try many times and a relatively long work time is required.

  As a method of stably peeling, for example, there are several methods as follows. The first is a method in which the polarizing plate is strongly fixed and a strong adhesive tape is used in order to simply improve the peeling force, but a change to the strong adhesive tape is not preferable because it involves an increase in cost. The second is a method that uses needles and blades to aim only at the protective film, and requires a high degree of accuracy, is difficult to maintain, and is misaligned with needles and blades and varies in thickness of members. May damage the polarizing plate.

  As a method for solving the problems of the above two methods, there is a third method in which a roller is reversely rotated to form a peeling trigger. For example, the following technique is disclosed. The rotating member and an auxiliary roller that rotates in the opposite direction, the end of the sticking member is turned up by the rotation of the rotating member, and the sticking member is sandwiched between the rotating member and the auxiliary roller and peeled off from the member to be stuck. is there. As a feature, a protrusion is formed on the surface of the rotating member to turn up the end of the sticking member, and the tip of the protrusion faces the rotation direction of the rotating member. Further, the protrusion is formed of a material having a low hardness with respect to the member to be pasted. (For example, see Patent Document 1)

  As another technique, the press roller is pressed against the surface of the protective film (sticking member) via the adhesive tape, the lower end of the adhesive tape is attached to the protective film surface, and then the press roller is once peeled off. After rotating the film body to the side edge of the film body in the opposite direction, sticking the tip of the protective film on the adhesive tape, and then pressing the presser roller against the surface of the protective film via the adhesive tape In addition, a technique is disclosed in which a protective film is peeled off by moving the protective film while rotating the protective film inwardly in the direction of the film body corresponding to the peeling direction (see, for example, Patent Document 2).

JP 2002-46935 A (page 4, FIG. 1) JP 2006-282924 A (summary, FIG. 7)

However, the conventional technique disclosed in Patent Document 1 has the following problems.
The first point is that when the protrusions formed on the surface of the rotating member are soft, a sufficient peeling force cannot be obtained and the peeling operation becomes unstable. On the contrary, when the protrusions are hard, When the direction of the object is directed more in the rotation direction, the possibility of damaging the adherend member, on the other hand, is obtained.
The second point is that the structure becomes complicated because an auxiliary roller is required to wind up even after the peeling member is formed.
The third point is not suitable for use in a clean room because a gear for synchronizing the rotation of the rotating member and the auxiliary roller is required and becomes a dust generation source.
The fourth point is that the peeling operation is discontinuous from the point where the peeling trigger is generated to the position sandwiched between the rotating member and the auxiliary roller, and the distance is far away, so there is no operation for grasping the peeling trigger and winding up. It becomes stable.
Further, in the prior art disclosed in Patent Document 2, in the stage of making the peeling trigger, it is equivalent to a peeling method in which a tape is attached to the tip of the protective film and pulled up in the relationship between the rotation direction of the press roller and the winding direction of the sticking member. Therefore, there is a problem that the peeling operation may become unstable.

  The present invention has been made to solve the above-described problems, and provides a sticking member peeling mechanism and a peeling method capable of performing a stable peeling operation and a winding operation without damaging a member to be stuck. For the purpose.

  The sticking member peeling mechanism according to the present invention is a sticking member peeling mechanism for peeling the sticking member from the sticking member, and includes a transport stage for fixing and feeding the sticking member, an adhesive tape for bonding the sticking member, and an adhesive Adhesive tape feed roller that feeds the tape in the direction opposite to the conveyance direction of the conveyance stage, an adhesive tape pressing roller that presses the adhesive tape against the adhesive member, and an adhesive tape pressing roller that is positioned so as not to contact the conveyance stage Positioning pressing means for applying a pressing force to the member.

  Further, the sticking member peeling method according to the present invention is a sticking member peeling method for peeling the sticking member from the member to be stuck, and the sticking member is fixed and transported to the transport stage, and the adhesive tape is fed by the adhesive tape feeding roller. The tape is fed in the direction opposite to the conveyance direction of the conveyance stage, and the adhesive tape pressing roller provided in the middle of the adhesive tape feed path starts the adhesive from the point when the tip of the adherend is conveyed to the vicinity of the lower part of the adhesive tape pressing roller. The tape is pressed against the sticking member, the sticking member is adhered to the adhesive tape and peeled off, and wound around the adhesive tape feeding roller.

  According to the sticking member peeling mechanism of the present invention, the transport stage for fixing and transporting the member to be pasted, the adhesive tape for bonding the sticking member, and the adhesive tape feeding for feeding the adhesive tape in the direction opposite to the transport direction of the transport stage A roller, an adhesive tape pressing roller that presses the adhesive tape against the sticking member, and a positioning pressing means that positions the adhesive tape pressing roller in a position not in contact with the transport stage and applies a pressing force to the sticking member. Therefore, since a peeling force can be continuously generated with respect to the sticking member, the peeling can be stably performed. Further, it is possible to obtain a peeling operation that is less likely to damage the adherend member.

  Further, according to the sticking member peeling method of the present invention, the member to be stuck is fixed and transported to the transport stage, and the adhesive tape is fed in the direction opposite to the transport direction of the transport stage by the adhesive tape feeding roller. With the adhesive tape pressing roller provided in the middle of the path, the adhesive tape is pressed against the adhesive member from the time when the tip of the member to be applied is conveyed near the lower part of the adhesive tape pressing roller, and the adhesive member is adhered to the adhesive tape. Since it peels and is wound around the adhesive tape feed roller, it is possible to continuously give a peeling force to the tip of the sticking member, so that it is possible to create a stable peeling trigger and to damage the sticking member. small.

Embodiment 1 FIG.
FIG. 1 is a side view showing a sticking member peeling mechanism 1 according to Embodiment 1 of the present invention, and FIG. 2 is a side view showing an adhesive tape control mechanism 3 in FIG.
The configuration of the workpiece 20 that is the target of peeling of the sticking member is such that the sticking member 21 is stuck on the surface of the sticking member 22. The sticking member 21 and the sticking member 22 have the same tip. Specific products include, for example, a polarizing plate of a liquid crystal display and a protective film attached to the polarizing plate.
The affixing member peeling mechanism 1 includes a conveyance stage 2, a pressure-sensitive adhesive tape control mechanism 3, and a controller 17 for firmly fixing and conveying the adherend member 22 of the work 20 by suction or the like.

  The transport stage 2 is fed by a feed shaft (not shown) and moved in the transport direction d by the driving force of a driving means (not shown). In addition, although this conveyance stage 2 is a trapezoid thing in the figure, the conveyor supported by the base board which can endure the pressing force of the below-mentioned adhesive tape pressing roller 6 may be sufficient. The transfer stage 2 is provided with a transmission portion 2a for transmitting a beam of a tip detection sensor 15 that detects the tip of a workpiece, which will be described later.

The adhesive tape control mechanism 3 has an adhesive tape feed roller 4, an adhesive tape roll 5, and an adhesive tape pressing roller 6. An adhesive tape 7 is set on the adhesive tape roll 5. The pressure-sensitive adhesive tape feed roller 4 has power to wind up the pressure-sensitive adhesive tape 7 and winds the pressure-sensitive adhesive tape 7 from the pressure-sensitive adhesive tape roll 5 while controlling the speed. An adhesive tape pressing roller 6 is disposed in the middle of the path. The adhesive tape pressing roller 6 is provided with positioning pressing means 14 for applying a pressing force to press the adhesive tape 7 against the sticking member 21 while positioning the adhesive tape 7 at a position where the adhesive tape 7 is not in contact with the transport stage 2. To do.
The adhesive tape pressing roller 6 and the adhesive tape roll 5 are freely rotatable.

When the adhesive tape feed roller 4 is rotationally driven in the b1 direction, the adhesive tape roll 5 rotates in the b2 direction, and the adhesive tape pressing roller 6 rotates in the b3 direction. The pressure-sensitive adhesive tape pressing roller 6 is given a pressing force in the pressing direction c.
With respect to the winding direction a of the adhesive tape feed roller 4, the transport stage 2 moves in the transport direction d so as to oppose it. That is, the adhesive tape 7 is sent in the direction opposite to the conveyance direction d of the conveyance stage 2. For this reason, a frictional force is generated between the adhesive tape 7 and the sticking member 21, and no slack is generated in the adhesive tape 7. The affixing member peeling mechanism 1 is a simple mechanism that operates with only two powers: a servo motor that rotates the adhesive tape feed roller 4 and a feed shaft of the transport stage 2.

The adhesive tape control mechanism 3 in FIG. 1 will be described in more detail with reference to FIG. The adhesive tape control mechanism 3 has an adhesive tape feed roller shaft 8, an adhesive tape pressing roller shaft 9, and an adhesive tape roll shaft 10. The pressure-sensitive adhesive tape pressing roller shaft 9 is arranged in a state of being inserted into a block 13 sandwiched between the pressing spring 11 and the pressing roller reference surface k of the position adjusting screw 12. The portions of the pressing spring 11, the position adjusting screw 12, and the block 13 are the positioning pressing means 14 described above. The positioning pressing means 14 may be any one that provides a pressing force to press the adhesive tape 7 while positioning the adhesive tape 7 by the adhesive tape pressing roller 6 at a position not in contact with the transport stage 2, and is limited to the configuration shown in the figure. is not.
The adhesive tape pressing roller 6 is pressed downward by the pressing spring 11 and positioned by the pressing roller reference surface k. The pressing pressure may be adjusted by adjusting the pressing pressure by providing a mechanism for adjusting the amount of compression of the pressing spring 11, or can be dealt with by replacing the pressing spring 11.

  The position of the pressure-sensitive adhesive tape pressing roller 6 can be changed by the position adjusting screw 12, and by adjusting the position of the lowest point of the pressure-sensitive adhesive tape 7 at a position sufficiently lower than the upper surface of the member 22 to be adhered, And it can respond also to the to-be-attached member 22 from which thickness differs. The distance between the lowest point of the adhesive tape 7 and the upper surface of the transport stage 2 is set to be equal to or greater than the variation in the thickness of the adhesive tape 7 so that the adhesive tape 7 and the transport stage 2 do not come into contact with each other. Will not be disturbed.

Next, returning to FIG. 1, the control unit will be described.
On the conveyance stage 2 side, a tip detection sensor 15 for detecting the tip position of the workpiece 20 is provided. Correspondingly, the transfer stage 2 is provided with a transmission part 2a. When an optical sensor such as a photoelectric sensor is used as the tip detection sensor 15, the sensor beam is transmitted through the transmission part 2a. The transmission part 2a may be a hole as long as it does not affect the adsorption, or may be configured by a glass window that does not affect the sensor beam quality.
On the other hand, on the side of the adhesive tape control mechanism 3, a measurement sensor 16 including a displacement meter or the like is provided for measuring the winding radius of the adhesive tape 7 wound around the adhesive tape feeding roller 4.

  Overall control is controlled by the controller 17. First, the workpiece 20 is placed on the transfer stage 2 and sent in the transfer direction d at a predetermined speed. When the tip detection sensor 15 detects that the tip position of the workpiece 20 has reached a predetermined position, the controller 17 receives this information, calculates the position immediately before the contact between the adhesive tape 7 and the affixing member 21 of the workpiece 20, and adheres to the adhesive. The rotation of the tape feed roller 4 is started. Further, the radius of the adhesive tape 7 wound around the adhesive tape feed roller 4 is measured by the measurement sensor 16, and the controller 17 receives the information, calculates the rotational speed, and controls the speed.

  FIG. 3 is a diagram for explaining a method of calculating the winding start timing of the adhesive tape feeding roller 4 and shows an enlarged contact portion between the adhesive tape pressing roller 6 of FIG. The total thickness of the sticking member 21 and the sticking member 22 is t1, and the distance between the lowermost end of the adhesive tape 7 and the transport stage 2 is t2. T2 is set to be sufficiently smaller than t1 so that the adhesive tape 7 is surely in contact with the tip of the sticking member 21. The radius of the adhesive tape pressing roller 6 is r1, and the thickness of the adhesive tape 7 is r2. The horizontal distance from the beam center of the tip detection sensor 15 to the center of the adhesive tape pressing roller 6 is L2, and the horizontal distance from the position where the adhesive member 21 and the adhesive tape 7 are in contact to the center of the adhesive tape pressing roller 6 is set. Is L1. The conveyance distance L from the workpiece detection position of the tip detection sensor 15 to the contact of the sticking member 21 with the adhesive tape 7 can be obtained by the following equations (1) and (2).

L = L2-L1 (1)
L1 = √ [(r1 + r2) ² − {(r1 + r2) − (t1−t2)} ² ] (2)

  The timing for starting the winding of the adhesive tape feed roller 4 is set to a timing that is less than the conveyance distance L after the tip detection sensor 15 detects the tip of the workpiece 20. Note that L is determined in consideration of member variation, and the winding start timing is determined in consideration of the conveyance speed and the sampling time of the tip detection sensor 15.

Next, the peeling / rolling operation of the sticking member peeling mechanism 1 will be described. Before describing the operation of the first embodiment, for comparison, first, the operation in the case of a conventional pasting member peeling mechanism similar to Patent Document 2 described in the background art section will be described with reference to FIG. .
4A is a side view, and FIG. 4B is an enlarged detailed view of a one-dot chain line portion of FIG. 4A. The same parts as those in the present embodiment are given the same reference numerals. As shown in FIG. 4, the rotation direction of the pressure-sensitive adhesive tape pressing roller 6 is a forward direction as shown by an arrow with respect to the conveyance direction d of the conveyance stage 2. In this case, since the bending amount of the sticking member 21 depends on the curvature of the pressure-sensitive adhesive tape pressing roller 6, in the mechanism, the curvature of the sticking member 21 is as large as the bending curvature similar to the first embodiment. It is impossible to do. For this reason, the peeling operation is unstable because a large peeling area n is peeled at once, and a large peeling force e is required.

  Further, depending on the processing method of the sticking member 21, as shown by the tip angle r in FIG. 4B, the tip corner of the sticking member 21 is rounded. Therefore, it is difficult to apply the peeling force e, and in addition to the adhesive force, a vacuum suction force due to the creation of the vacuum part v is also generated. Therefore, a strong peeling force e is required, and the peeling operation becomes unstable.

FIG. 5 is an explanatory diagram for explaining the peeling and winding operation of the sticking member peeling mechanism 1 according to the first embodiment. 5A to 5E show the behaviors of the member 22 to be pasted and the pasting member 21 during the peeling operation in time series.
FIG. 6 is a flowchart for explaining the peeling and winding operation. Hereinafter, the peeling and winding operation will be described with reference to FIGS.

FIG. 5A shows the operation of turning up the tip of the sticking member.
First, the workpiece 20 is fixed to the transfer stage 2 by suction or the like (step 1 in FIG. 6, hereinafter abbreviated as S1) and transferred in the transfer direction d.
Next, the tip position of the workpiece 20 is detected by the tip detection sensor 15 made of a photoelectric sensor or the like, and the position where the adhesive tape 7 and the sticking member 21 are in contact is calculated (S2).
Next, immediately before the contact, the adhesive tape 7 starts to be fed in a direction against the conveyance of the workpiece 20 (S3). By this operation, the adhesive tape 7 is not wasted.

  If the conveyance stage 2 continues to be fed, the lowest point of the adhesive tape 7 is located at a position sufficiently lower than the upper surface of the member 22 to be adhered, so that the tip of the adhesive member 21 always comes into contact with the end surface of the adhesive tape 7. Then, peeling is started (S4). At this time, since the adhesive tape 7 has already started to be fed, the peeling force e can be continuously applied from the moment when the adhesive tape 7 comes into contact with the adhesive member 21, and the adhesive member 21 can be turned up stably. Can do.

  As the workpiece 20 is conveyed, the pressing spring 11 pressing the adhesive tape pressing roller 6 against the sticking member 21 contracts, and the workpiece 20 is conveyed so as to push the adhesive tape pressing roller 6 away, and the adhesive tape pressing roller 6 escapes. It rises in the direction c1. At this time, the adhesive tape 7 is constantly pressed against the sticking member 21 by the spring force of the pressing spring 11. In order to improve the peeling force, (1) the pressing pressure of the adhesive tape pressing roller 6 is increased by replacing the pressing spring 11 or adjusting the spring force of the pressing spring 11, and (2) the feeding speed of the adhesive tape 7 is increased. And (3) increasing the adhesive strength of the adhesive tape 7. The stable condition may be set by adjusting the peeling force e in the order of (1) to (3), which is unlikely to increase the cost.

Thus, in this embodiment, since the force acts in the direction of bending the sticking member 21 during the turning operation of the sticking member, the peeling area to be peeled at a time is small, and the necessary peeling force e is small. The raising operation is stabilized.
Further, in the operation of turning up the tip of the sticking member of the present embodiment, the peeling force e is concentrated on a small peeling area, and from the tip of the interface between the sticking member 21 and the sticking member 22 regardless of the processed shape of the sticking member. Since the peeling force e can be reliably applied, the peeling operation is stable, which is superior to the method shown in FIG.

  Next, FIG. 5B is a side view showing an operation of creating the peeling trigger m of the sticking member 21. While feeding the adhesive tape 7, the conveyance stage 2 is sent to a place where the lowest point of the adhesive tape 7 and the tip of the member 22 to be pasted substantially coincide (S5). Thereby, the peeling trigger m can be created. In addition, peeling trigger means the front-end | tip part of the sticking member 21 of the state peeled from the to-be-bonded member 22. FIG.

  At this time, the pressing pressure of the pressure-sensitive adhesive tape pressing roller 6 is selected as the pressing spring 11 or the compression amount adjusting mechanism (not shown) of the pressing spring 11 according to the hardness and thickness of the bonding member 21 so that the bonding member 21 is bent. Set with. During the operation of creating the peeling trigger m of the sticking member 21, the adhesive tape 7 is being fed, and the feeding operation of the adhesive tape 7 is stopped when the lowest point of the adhesive tape 7 and the tip of the adherend member 22 are substantially coincident. (S6). Thereby, even if the adhesive tape 7 and the to-be-bonded member 22 contact, the influence on peeling operation | movement can be decreased.

FIG.5 (c) is a side view which shows a to-be-bonded member protection operation | movement. In a state where the adhesive tape pressing roller 6 is not rotated and the feeding operation of the adhesive tape 7 is stopped, the conveyance stage 2 is sent until the adhesive member 21 completely enters between the lowest point of the adhesive tape 7 and the member 22 to be applied. (S7). By this operation, since the bent portion of the adhesive tape 7 passes through the lowermost end portion of the adhesive tape pressing roller 6 and is positioned further to the right, the adhesive tape 7 and the adherend member 22 do not come into contact thereafter. The peeling operation is not hindered and the adherend member 22 is not contaminated. Since the bent peeling trigger m enters the vicinity of the lowest point of the pressure-sensitive adhesive tape 7, the pressure-sensitive adhesive tape 7 and the adherend member 22 do not come into contact with each other, and the peeling operation is not hindered.
Since the transport distance at this time changes depending on conditions such as the hardness and thickness of the sticking member 21 and the pressure of the adhesive tape, the condition is set on the actual product.

FIG.5 (d) is a side view which shows the sticking member peeling and winding start operation | movement. The adhesive tape pressing roller 6 is rotated again to restart the feeding operation of the adhesive tape 7 (S8).
FIG.5 (e) is a side view which shows sticking member peeling and winding-up operation | movement. The peeling operation proceeds while controlling the speed of the adhesive tape feed roller 4 so that the transport speed of the transport stage 2 is equal to the feed speed of the adhesive tape 7. As a result, the sticking member 21 is peeled off from the sticking member 22 and is wound around the adhesive tape feed roller 4 together with the adhesive tape 7. Regarding the speed of the adhesive tape feed roller 4, the radius of the adhesive tape 7 taken up by the measurement sensor 16 is measured, and radius information is input to the controller 17 that controls the adhesive tape feed roller 4 to calculate the rotation speed. When all the peeling is completed, the winding, conveying, and feeding operation of the adhesive tape 7 are stopped (S9). By winding the adhesive tape 7 around the adhesive tape feed roller 4, a separate winding mechanism for the adhesive tape 7 is not required, and the peeling mechanism can be simplified.

FIGS. 7A and 7B are explanatory views when the adhesive tape feeding is stopped for comparison in the winding operation of the sticking member, FIG. 7A is a side view, and FIG. 7B is a top view. Even if the feeding of the adhesive tape 7 is stopped at the stage of FIG. 5D, the peeling operation is possible if the carrying stage 2 is carried in the carrying direction d, but in this case, the following problems occur. .
The sticking member 21 and the sticking member 22 are installed on the transport stage 2 as shown in the top view. Therefore, the peeling area n2 in the middle of peeling is larger than the peeling area n1 in the early stage of peeling, and a larger peeling force is required in the middle of peeling. When feeding of the adhesive tape 7 is stopped, the adhesive fixing area p on the back surface of the adhesive tape 7 and the adhesive member 21 is not changed, and only the peel area is increased. During the peeling / rolling operation, the adhesive fixation between the adhesive tape 7 and the back surface of the sticking member 21 may be released, and the peeling operation may fail. As a result, the peeling operation becomes unstable.

On the other hand, in the sticking member peeling / rolling operation of the present embodiment, as shown in FIGS. 5D and 5E, the adhesive tape 7 and the sticking member are fixed to each other as the peeling operation proceeds. Since the area p increases and the adhesive fixing force increases, it is considered that the peeling operation is stable and excellent throughout the peeling operation.
In order to further ensure this operation, the speed of the adhesive tape feed roller 4 is controlled so that the transport speed of the transport stage 2 and the feed speed of the adhesive tape 7 are equal. By carrying out like this, since the adhesive tape 7 and the sticking member 21 never leave | separate from the tip turning-up operation of the sticking member 21 to peeling completion, a winding operation can be performed stably.

  As described above, according to the sticking member peeling mechanism of the first embodiment, the sticking member peeling mechanism that peels the sticking member from the member to be stuck, the conveyance stage for fixing and carrying the sticking member, and the sticking member Adhesive tape, adhesive tape feed roller that feeds the adhesive tape in the direction opposite to the transport direction of the transport stage, adhesive tape pressing roller that presses the adhesive tape against the adhesive member, and the adhesive tape pressing roller in contact with the transport stage And a positioning pressing means for applying a pressing force to the sticking member, so that a peeling force can be continuously generated on the sticking member, so that the peeling can be performed stably. it can. Further, it is possible to obtain a peeling operation that is less likely to damage the adherend member.

  Further, the positioning pressing means includes a pressing spring that presses the adhesive tape pressing roller toward the member to be pasted, and an adjustment screw that can adjust the position of the adhesive tape pressing roller, so that precise positioning is not required. In addition, it is possible to flexibly cope with differences in thickness and variations between the pasting member and the pasting member. Therefore, the stable contact operation | movement of an adhesive tape and a sticking member and the peeling operation | movement of a sticking member are attained.

  Moreover, according to the sticking member peeling method of Embodiment 1, it is a sticking member peeling method which peels a sticking member from a to-be-sticked member, Comprising: A sticking member is fixed to a conveyance stage, it conveys, and an adhesive tape is an adhesive tape. The feed roller feeds in the direction opposite to the transport direction of the transport stage, and the tip of the member to be pasted is transported near the lower part of the adhesive tape pressing roller by the adhesive tape pressing roller provided in the middle of the adhesive tape feeding path. Since the adhesive tape is pressed against the adhesive member from the point of time, and the adhesive tape is adhered to the adhesive tape and peeled off and wound around the adhesive tape feed roller, a continuous peeling force can be applied to the tip of the adhesive member. Thus, it is possible to stably create a peeling trigger, and there is little concern of damaging the sticking member.

  In addition, since the leading end detection sensor detects the leading end in the transport direction of the pasting member transported on the transport stage and starts feeding the adhesive tape immediately before the leading sticking member contacts the adhesive tape, continuous peeling Since the adhesive surface that does not contribute to the peeling force can be substantially eliminated without hindering the force, the adhesive tape is not wasted.

  Also, when the tip of the adherend comes near the lowermost end of the adhesive tape pressing roller and comes into contact with the adhesive tape, the feeding of the adhesive tape is temporarily stopped and the adhesive member completely enters between the adhesive tape and the adherend. Since the adhesive tape feed is resumed after the to-be-adhered member has been conveyed in the conveying direction, the adhesive tape does not come into contact with the to-be-adhered member so as to hinder the exfoliation operation, and it is possible to reliably create an exfoliation trigger. In addition, contamination of the adherend can be prevented.

  Moreover, since the adhesive tape feeding speed by the adhesive tape feeding roller is set to be the same as the conveying speed, the peeling and winding operations are stabilized throughout the peeling process.

  Furthermore, the radius of the adhesive tape wound around the adhesive tape feed roller is measured by a measurement sensor, and the feed speed of the adhesive tape is calculated based on the measured value and controlled to match the transport speed of the transport stage. Therefore, speed control can be easily performed, and the peeling and winding operations are stabilized throughout the peeling process.

  In the present invention, the embodiments can be appropriately changed or omitted within the scope of the invention.
