Description

Peeling apparatus and peeling method

The present invention relates to a peeling apparatus and a peeling method in which, for example, a technique for peeling a release paper of a double-sided tape as an adhesive material is applied when a flat workpiece is bonded.

Generally, a liquid crystal panel is configured by laminating a liquid crystal module, a protective sheet for protecting the surface, a touch panel for operation, and the like. These liquid crystal modules, protective sheets, touch panels, etc. (hereinafter referred to as “workpieces”) are built into the housing of the liquid crystal module, and in order to avoid contact with the liquid crystal glass due to deformation of the protective panel or touch panel. There was a space.

However, if an air layer enters between the workpieces, the visibility of the display surface decreases due to external light reflection. In order to cope with this, bonding is performed by using a bonding material such as a double-sided tape or an adhesive so that a layer filling the space between the workpieces is formed. For this reason, the manufacture of a liquid crystal panel requires a bonding apparatus that prepares the bonding material for at least one workpiece and performs bonding.

両面 Double-sided tape is generally used as an adhesive for bonding workpieces. As for this double-sided tape, the one sticking surface is affixed beforehand to one side of a flat plate-shaped workpiece. And the workpiece | work is bonded together by peeling the peeling paper of an opposite surface with a peeling apparatus, and crimping | bonding to the other workpiece | work. For example, as shown in FIG. 10, the release papers F1 and F2 are attached to the adhesive tape T2 delivered by the delivery reel L1, and the release papers F1 and F2 are pulled from the double-sided tape T1 while being taken up by the take-up reel L2. The method of peeling is performed (refer patent document 1).

The details of the peeling procedure using this peeling device are as follows. That is, the adhesive tape T2 is pressure-bonded to the release paper F1 of the double-sided tape T1 attached to the workpiece S1 by the peeling head L3 made of a pressure roller (FIG. 10A). When rotation of the delivery reel L1 and the take-up reel L2 is stopped and the take-up reel L2 is moved rearward (rightward in the figure), the adhesive tape T2 is pulled rearward, so that the peeling head H moves. The release paper F1 is peeled off (FIG. 10B).

Next, when the peeling head L3 is moved forward while rotating the take-up reel L2 in the take-up direction and moving it forward (leftward in the figure), the supply reel L1 rotates and the adhesive tape T2 is sent out. (FIG. 10C). Thereafter, the release paper F2 of the next workpiece S1 is peeled by the same procedure as described above (FIG. 10D).

JP 2002-332160 A

By the way, in the case of the prior art as described above, by pulling the adhesive tape T2, the peeling head H is moved and the release paper F1 is peeled off. Therefore, the moving distance required for the take-up reel T2 is the distance of the release paper F1. It becomes longer than the length from the start end to the end (movement distance of the peeling head H). For this reason, the part z which does not use an adhesive tape arises between the release paper F1 affixed previously, and the release paper F2 affixed next, and waste increases.

The present invention has been proposed in order to solve the above-described problems of the prior art, and its main object is to provide a peeling apparatus and a peeling method that can use an adhesive tape without waste. is there.

In another aspect, the moving distance of the release paper attached to the adhesive tape in the supply direction is such that the end of the release paper does not interfere with the beginning of the release paper to be attached next. To do.

In the above aspect, the waste of the adhesive tape can be reduced as much as possible by bringing the end of the preceding adhesive tape and the start of the succeeding adhesive tape close to each other.

Another aspect includes a conversion unit that converts the supply direction of the adhesive tape so that the supply of the adhesive tape by the supply unit is performed from a direction different from the longitudinal direction of the adhesive tape in the peeling head. And

In the above-described aspect, since the supply direction of the adhesive tape from the supply unit is different from the longitudinal direction of the adhesive tape in the peeling head, the apparatus space in the longitudinal direction can be reduced.

In another aspect, a guide member for guiding the movement of the adhesive tape is provided between the supply unit and the separation head and between the separation head and the recovery unit, and the separation head, the guide member, and The unit having the conversion unit is configured to be replaceable.

In the above aspect, the supply unit can be arranged at a position different from the longitudinal direction of the adhesive tape in the peeling head by the conversion unit. For this reason, the supply unit and the recovery unit are left as they are, and a plurality of units with different arrangements of guide members for the peeling head and the conversion unit are prepared and exchanged to cope with peeling of release paper from workpieces at different positions. it can.

In another aspect, a guide member for guiding the movement of the adhesive tape is provided between the supply unit and the peeling head and between the peeling head and the recovery unit, and the adhesive tape is exchanged with the guide member. Thus, the guide member is disposed so as to be able to cope with peeling of the release paper from the work on the upper side and peeling of the release paper from the work on the lower side.

These operation timings and operation amounts are set as described in the following actions. Further, the input / output interface 460 is a means for controlling signal conversion and input / output with each unit to be controlled.

[Action]
The operation of the present embodiment having the above-described configuration is as follows. Note that a method for controlling the peeling apparatus according to the procedure described below and a computer program for operating the control apparatus are also one embodiment of the present invention.

Suppose that one adhesive surface of the double-sided tape T1 is attached to the work S1. At this time, the release paper F is stuck on the other surface of the double-sided tape T1.

The peeling of the release paper F by the peeling device 3 is performed as follows. That is, as shown in FIG. 6A, the head controller 420 moves the peeling head 33a forward by the head cylinder 33b, and the unit controller 430 drives the unit elevating cylinder 35 to 1 unit U1 is lowered and the peeling adhesive tape T2 is pressed against the edge (starting edge) of the release paper F of the double-sided tape T1 in the workpiece S1.

The delivery reel control unit 410 and the brake control unit 441 brake the delivery reel 31a and the take-up reel 34a by controlling the

brake mechanisms

31b and 34c. In this state, the lifting control unit 442 operates the reel lifting mechanism 34b to lower the take-up reel 34a. Then, the peeling head 33a moves backward while the adhesive tape T2 is pulled downward. At this time, as shown in FIG. 6B, the release paper F in contact with the adhesive tape T2 is attached to the adhesive tape T2 and peeled off.

Then, the brake mechanism 31b releases the brake of the delivery reel 31a, and the rotation control unit 443 operates the reel rotation mechanism 34d to rotate the take-up reel 34a in the winding direction, while the lift control unit 442 operates the reel lift mechanism. 34b is operated to raise the take-up reel 34a. At this time, the head controller 420 moves the peeling head 33a forward by the head cylinder 33b. Thereby, the peeling head 33a and the adhesive tape T2 return to the state in which the release paper F is peeled from the next workpiece S1.

Note that the above describes the case where the release paper F is peeled from the lower workpiece S1 using the first unit U1, but the adhesive tape T2 is attached to the release paper F by raising the second unit U2. When the release paper F is peeled off from the upper workpiece S2 by pressing, the basic operation procedure is the same (see FIGS. 7A and 7B).

Next, details of the control of the moving amount and moving direction of the adhesive tape T2 in the present embodiment will be described with reference to FIG. In the following description, in order to facilitate understanding of the principle, description of the conversion of the moving direction of the adhesive tape T2 by the conversion unit 32, the

guide rollers

33e, 33g, etc. is omitted. Further, the release paper that is first attached to the adhesive tape T2 is F1, and the release paper that is subsequently attached is F2.

First, the adhesive tape T2 is pressed against the release paper F1 by the release head 33a (FIG. 8A). Then, by moving the take-up reel 34a, the release paper F1 is released while the release head 33a is retracted (FIG. 8B). The amount of movement of the take-up reel 34a is set to be 2x, where x is the distance from the start to the end of peeling of the release paper F1. This is to secure the distance necessary for adhering the entire length of the release paper F1 to the adhesive tape T2 and the distance required for moving the release head 33a from the start end to the end of the release paper F1.

Next, the take-up reel 34a is rotated to take up the adhesive tape T2 (FIG. 8C), and the take-up reel 34a is moved back to the initial position (FIG. 8D), and the peeling head. 33a is advanced and returned to the beginning of the release paper F1 (FIG. 8E). The amount of rotation of the take-up reel 34a at this time is set so that the adhesive tape T2 is taken up by x, and the amount of movement of the take-up reel 34a is set to x. As a result, the rear end of the release paper F1 previously attached to the adhesive tape T2 returns to the front end of the release head 33a.

Further, the adhesive tape T2 is pressed against the release paper F2 by the release head 33a (FIG. 8 (F)). At this time, since the rear end of the release paper F1 has returned to the front end of the release head 33a, the start end of the release paper F2 is adhered immediately after the rear end of the release paper F1. Then, in the same manner as described above, the release paper F2 is peeled off by moving the take-up reel 34a while retracting the peeling head 33a (FIG. 8G). Thereby, the space | interval y of the starting edge of the rear edge of the previous release paper F1 and the rear release paper F2 can be made very narrow.

[effect]
According to the present embodiment as described above, the following effects can be obtained. That is, since the interval between the release papers F that are sequentially attached to the adhesive tape T2 can be reduced, the waste of the adhesive tape T2 is reduced. In particular, as described above, by setting the amount of rotation and the amount of movement of the take-up reel 34a, the interval between the release sheets F can be almost eliminated.

More specifically, as shown in FIG. 8B, the moving distance of the adhesive tape T2 when peeling the release paper F1 is twice the distance x from the start to the end of the release of the release paper F1. Become. If the peeling head 33a is advanced as it is and a new adhesive tape T2 is sent out, a useless interval of the distance x is left between the start end of the next release sheet F2 and the end of the release sheet F1. In this embodiment, this useless interval can be eliminated by moving the adhesive head T2 back by the distance x while moving the peeling head 33a forward.

Moreover, since the peeling head 33a in the peeling apparatus 3 is inclined, the pressure-sensitive adhesive tape T2 can be started to be pressed from the ends of the workpieces S1 and S2, and the release paper F can be reliably peeled off. Furthermore, since the release paper F is peeled off by the movement of the take-up reel L1, it is possible to prevent a peeling line from appearing on the double-sided tape T1 by making the moving speed constant.

In addition, the peeling head 33a is inclined, the conversion unit 32 causes the supply unit 31 to be removed from the longitudinal direction of the adhesive tape T2 in the peeling unit 33, and the moving direction of the take-up reel 34a is up and down. Therefore, the required space in the depth direction can be reduced. Advantages of such a peeling device 3 include, for example, as shown in FIGS. 10A to 10D, a take-up reel L1, a feed reel L2, and a peel head L3 are arranged, and the take-up reel L1 is attached to the adhesive tape T2. This is clear even when compared with the conventional example configured to move in the longitudinal direction.

Also, the peeling device 3 can easily cope with peeling of the release paper F from the lower work S1 and peeling of the release paper F from the upper work S2 by exchanging the units U1 and U2. For example, in the conventional example as shown in FIG. 10, the arrangement itself of the take-up reel L1 and the delivery reel L2 must be changed between the case of corresponding to the lower work S1 and the case of corresponding to the upper work S2. Therefore, unitization is difficult. On the other hand, the peeling apparatus 3 of the present embodiment can be unitized as described above, and can support the upper and lower workpieces S1 and S2 by exchanging the units U1 and U2.

For example, by using the apparatus including the guide rollers 33c to 33g shown in FIG. 6 and FIG. 7, the adhesive tape T2 can be replaced as shown in FIG. It is possible to cope with upper side peeling and lower side peeling only.

[Other Embodiments]
The present invention is not limited to the embodiment as described above. For example, the detailed configuration of the peeling apparatus is not limited to that shown in the above embodiment. For example, the release head may be configured to be able to press the adhesive tape against the release paper while allowing the adhesive tape to move, and the drive mechanism may be configured to be able to contact and separate from the release paper.

Also, the position and number of guide rollers can be freely set. Further, the conversion angle of the conversion unit is not limited to a right angle as long as the sending unit is removed from the longitudinal direction of the adhesive tape of the peeling head. Furthermore, it is not always necessary to change the angle of the adhesive tape by the guide roller or the conversion unit. For this reason, as shown in FIG. 8, the structure which a take-up reel moves back is also applicable. Further, the peeling head, the guide member, the conversion unit, and the like may have a structure that rotates when the adhesive tape moves, or a structure that slides the adhesive tape without rotating.

Also, how to set the operation timing and operation amount set in the storage unit is free. For example, the movement amount may be set not by the movement distance and the rotation amount but by the movement time and the rotation time. The position of the take-up reel in the collection unit may be fixed, and the above-mentioned adhesive tape may be moved by rotating the take-up reel. In such a case, it is desirable to keep the moving speed constant by using a dancer roller, a nip roller, etc. (prevention of peeling lines).

Further, the amount of movement when returning the adhesive tape to the delivery section side may be less than the above-mentioned distance x as an upper limit. Although it depends on the length of the workpiece and the release paper, even when returning about 1 mm to 1 cm, the useless interval of the adhesive tape may be reduced as compared with the prior art. In consideration of the thickness of the peeling head, the expansion and contraction of the adhesive tape, etc., the amount of movement of the adhesive tape for avoiding the overlap between the release papers F1 and F2 needs to be completely matched with the distance from the start end to the end of the release paper. There are some differences.

The work to be bonded is typically a cover panel and a liquid crystal module (a laminate of a display panel and a backlight), but is not limited thereto. In other words, the workpiece may be any object as long as it is an object to be bonded by the double-sided tape.
