Description

  The present invention relates to a peeling apparatus for peeling a separator covering a sheet-like adhesive material.

  Two adherends may be bonded together through an adhesive material such as a double-sided tape. Such a bonding process generally proceeds as follows. First, an adhesive material whose one surface is covered with a separator is attached to one adherend. Then, after peeling this separator and exposing the other surface of the adhesive material, the other adherend is stuck.

  In order to adhere the adherends to each other neatly, it is required that the separator is peeled off, that is, the surface of the exposed adhesive material is flat and has no unevenness. As a method for separating the separator, there are a method disclosed in Patent Document 1 or Patent Document 2 as well as a method of peeling one by one by hand.

  Patent Document 1 discloses a technique in which a peeling adhesive tape is pressure-bonded to the surface of an adhesive protective film affixed to the surface of a thin plate-like article, and the protective film is peeled off from the thin plate-like article by the adhesive force of this adhesive tape. ing.

  Patent Document 2 discloses a technique of causing a thin film by a thin film triggering means that causes a part of the thin film attached to the substrate and blowing the compressed air between the caused thin film and the substrate to peel the thin film. Has been.

  When the separator is peeled by a human hand, the peeling angle between the separator and the pressure-sensitive adhesive material and the pulling speed of the separator cannot be made constant, which causes a problem that the pressure-sensitive adhesive material floats from the adherend.

  The peeling method disclosed in Patent Literature 1 consumes a peeling pressure-sensitive adhesive tape, and thus has a problem of high running cost.

  In general, since the edge of the separator protrudes from the outer periphery of the pressure-sensitive adhesive material, when the pressure-sensitive adhesive tape is pressure-bonded to the separator, the degree of adhesion between the outer periphery of the separator and the pressure-sensitive adhesive tape tends to be insufficient. For this reason, when causing the peeling pressure-sensitive adhesive tape, the peeling pressure-sensitive adhesive tape peels off from the separator, and a situation occurs in which the separator cannot be peeled off from the pressure-sensitive adhesive material.

  In the peeling method disclosed in Patent Document 2, since compressed air is blown by the nozzle, there is a possibility that dust, dust, or the like is wound up. There is a problem that the adhesion between the adhesive material and the adherend cannot be performed neatly due to adhesion of dust or the like on the adhesive material.

  This invention is made | formed in view of the said matter, The place made into the objective is to provide the peeling apparatus of the separator which can peel a separator neatly.

(Embodiment 1)
The peeling apparatus 1 according to Embodiment 1 will be described. As shown in the front view of FIG. 1 and the side view of FIG. 2, the peeling device 1 mainly includes a main body 11, a pressing head 14, and a clamping device 15, which are arranged above the mounting table 21. ing.

  The main body 11 supports the pressing head 14 via the support point 13. The main body 11 is connected to an elevating cylinder 12 and is configured to be movable up and down by the elevating cylinder 12. The upper part of the lifting cylinder 12 is connected to a support rail (not shown), and the main body 11 is configured to be movable back and forth in the peeling direction along the upper surface of the mounting table 21.

  The pressing head 14 is attached to the main body via the support point 13. A surface of the pressing head 14 facing the mounting table 21 (hereinafter referred to as a head surface) is formed in an arc shape so as to protrude toward the mounting table 21. The pressing head 14 is configured to be rotatable around a support point 13 by a driving device such as a motor (not shown).

  A clamping device 15 is provided behind the pressing head 14 in the peeling direction. This clamp device is composed of an arm 15a and a clamp head 15b. The upper part of the arm 15a is connected to the end of the pressing head 14, and can be rotated by a driving device such as a motor (not shown) with this connection point as a fulcrum. The clamp head 15b is slidable in the longitudinal direction inside the arm 15a, and the length of the clamp device 15 is extendable.

  The mounting table 21 is a table on which an adherend 33 on which a sheet-like adhesive material 32 covered with a separator 31 described later is attached is placed.

  Subsequently, the peeling operation of the peeling apparatus 1 will be described with reference to FIGS.

  First, an adherend 33 to which a sheet-like adhesive material 32 coated with a separator 31 is attached is prepared. The adherend 33 is arranged on the mounting table 21 so that the separator 31 faces the pressing head 14. In addition, the adherend 33 may be arrange | positioned on the mounting base 21, and the sheet-like adhesive material 32 with which the separator 31 was covered may be stuck in this state.

  The sheet-like adhesive material 32 here is not particularly limited as long as it is a sheet-like member having adhesiveness on both surfaces. Examples of the separator 31 include, but are not limited to, a mount or a protective film that protects the surface of the sheet-like adhesive material 32.

  Subsequently, as shown in FIG. 3, the pressing head 14 is rotated clockwise, and the rear end portion in the peeling direction of the head surface of the pressing head 14 and the edge of the separator 31 are aligned. Then, the main body 11 is lowered through the lifting cylinder 12. As the main body 11 is lowered, the head surface end of the pressing head 14 presses the separator 31 toward the sheet-like adhesive material 32 as indicated by an arrow F.

  Subsequently, as illustrated in FIG. 4, the clamp device 15 holds the edge of the separator 31 between the clamp head 15 b and the head surface end of the pressing head 14. Since the clamp device 15 is rotatable and telescopic as described above, the arm 15a is rotated and the clamp head 15b is expanded and contracted so that the edge of the separator 31 is pressed against the head surface of the pressing head 14. Hold it. In addition, the outer periphery of the separator 31 is configured to protrude from the sheet-like adhesive material 32 so as to be easily held. As a result, only the separator 31 is held between the clamp head 15 b and the head surface end of the pressing head 14.

  Subsequently, as shown in FIG. 5, the main body 11 is advanced in the peeling direction at a constant speed while maintaining the state in which the separator 31 is pressed by the pressing head 14. As the main body 11 moves forward, the pressing head 14 rotates counterclockwise with the support point 13 as a fulcrum. Since the edge of the separator 31 remains nipped as described above, the edge of the separator 31 is pulled up by the rotation of the pressing head 14. In this way, a part of the separator 31 is peeled off from the sheet-like adhesive material 32. In other words, since the separator 31 is peeled after the separator 31 is pressed by the head surface of the pressing head 14 because the separator 31 is pressed by the pressing head 14, the sheet-like adhesive material 32 and the adherend are peeled off. The degree of adhesion with 33 is improved, and the sheet-like adhesive 32 is not peeled off from the adherend 33 when the separator 31 is peeled off.

  Thereafter, as shown in the order of FIGS. 6 and 7, the main body 11 is further advanced in the peeling direction, so that the separator 31 is gradually separated from the sheet-like adhesive material 32 and peeled off. Then, as shown in FIG. 8, the separator 31 is completely peeled from the sheet-like adhesive material 32.

  In this way, the separator 31 can be peeled while pressing the separator 31 with the pressing head 14 having an arcuate head surface, and the peeling angle (the separator 31 and the sheet that have been lifted) by the rotation of the pressing head 14 having an arcuate head surface. The contact angle formed by the adhesive material 32 can be made constant, and the separator 31 can be peeled at a constant speed by advancing the main body 11 in the peeling direction at a constant speed. As a result, when the separator 31 is peeled off, the sheet-like adhesive material 32 does not float from the adherend 33, and the surface of the sheet-like adhesive material 32 exposed after the separator 31 is peeled off does not cause unevenness. In addition, the degree of adhesion between the sheet-like adhesive material 32 and the adherend 33 is increased, and the degree of adhesion is constant over the entire area. Thus, since the exposed surface of the sheet-like adhesive material 32 is a flat surface without unevenness, the other adherend (not shown) can be neatly adhered to the sheet-like adhesive material 32.

  Furthermore, for the same reason, the adherend 33 is not lifted from the mounting table 21 by being pulled by the separator 31 during the peeling. Usually, the peeling device is driven continuously and a large number of separators 31 are sequentially peeled off. However, when the adherend 33 is lifted, the operation of the peeling device must be stopped. However, in this embodiment, since the lifting of the adherend 33 can be prevented, the operation stop of the peeling device can be suppressed and the occurrence of defective products can be suppressed, so that the production efficiency is improved.

(Embodiment 2)
Then, the peeling apparatus 2 which concerns on Embodiment 2 is demonstrated. As shown in the front view of FIG. 9 and the side view of FIG. 10, the peeling device 2 includes a main body 11, a pressing head 14, a clamping device 15, a pressing roller 16, and a stopper 17. It is arranged above the table 21.

  Since the main body 11, the clamp device 15, the mounting table 21, and the elevating cylinder 12 are the same as those in the first embodiment described above, description thereof is omitted.

  The pressing head 14 is attached to the main body via the support point 13. The rear surface of the pressing head 14 facing the mounting table 21 (hereinafter referred to as a head surface) is formed in an arc shape in the peeling direction. The pressing head 14 is configured to be rotatable around a support point 13 by a driving device such as a motor (not shown).

  And the recessed part is formed in the head surface of the press head 14 from the center part to the peeling direction front part. And the press roller 16 is provided in this recessed part. The pressing roller 16 is set to have substantially the same width as the pressing head 14 so that the separator 31 can be pressed over almost the entire area.

  Further, the main body 11 is provided with a rod-like stopper 17 that fixes the counterclockwise rotation of the pressing head 14 at an arbitrary angle as a rotation angle control mechanism of the pressing head 14.

  Next, the peeling operation of the peeling device 2 will be described with reference to FIGS.

  The process until the edge of the separator 31 shown in FIG. 11 is held between the pressing head 14 and the clamp head 15b is the same as that in the first embodiment.

  As shown in FIG. 12, the main body 11 is advanced in the peeling direction. As the main body 11 moves forward, the pressing head 14 rotates counterclockwise. Since the edge of the separator 31 is pinched, the separator 31 is separated from the sheet-like adhesive material 32. While the pressing head 14 presses the separator 31, the separator 31 is separated from the sheet-like adhesive material 32, so that the sheet-like adhesive material 32 does not float from the adherend 33 and a part of the separator 31 is sheet-like adhesive material. 32 is peeled off.

  Then, as the rotation of the pressing head 14 progresses, the pressing roller 16 comes into contact with the separator 31 and presses the separator 31 against the sheet-like adhesive material 32 as indicated by an arrow F. The rotation of the pressing head 14 stops when the upper part of the pressing head 14 comes into contact with the stopper 17.

  As shown in FIG. 13, when the main body 11 is further advanced in the peeling direction, the pressing head 14 follows and moves in the peeling direction while maintaining a certain angle. By the movement of the main body 11, the pressing roller 16 rotates and advances while pressing the separator 31 against the sheet-like adhesive material 32. Then, since the edge of the separator 31 is held between the head surface of the pressing head 14 and the clamp head 15b, the separator 31 is gradually peeled off from the sheet-like adhesive material 32.

  And the separator 31 can be completely peeled from the sheet-like adhesive material 32 by further advancing the main body 11 in the peeling direction in the order of FIGS.

  Thus, the separator 31 is peeled off after being pressed by the pressing roller 16. Since the degree of adhesion between the sheet-like adhesive material 32 and the adherend 33 is increased by the pressing of the pressing roller 16, it is possible to prevent the sheet-like adhesive material 32 from being peeled from the adherend 33.

  Thus, the separator 31 is pressed by the arc-shaped pressing head 14 in the first half of the peeling operation, and the separator 31 is pressed by the pressing roller 16 after the middle of the peeling operation. Thereby, similarly to Embodiment 1, the sheet-like adhesive material 32 does not rise, and the surface of the sheet-like adhesive material 32 exposed after the separation of the separator 31 does not cause unevenness. The exposed surface of the sheet-like adhesive material 32 is a flat surface without unevenness, and the other adherend (not shown) can be neatly adhered to the sheet-like adhesive material 32.

  Similarly to the first embodiment, the adherend 33 is not lifted from the mounting table 21 by being pulled by the separator 31 during the peeling. For this reason, even if it operates a peeling apparatus continuously, while not having to stop a peeling apparatus, generation | occurrence | production of inferior goods can also be suppressed and production efficiency improves.

  Moreover, in the peeling apparatus 2 which concerns on this Embodiment 2, since the press roller 16 is used, if the sufficient back-and-forth movement to a peeling direction is possible, the separator 31 of various lengths can be peeled. This is particularly effective when the separator 31 longer than the length of the pressing head 14 in the peeling direction is peeled off.

  In the above description, the rotation angle control mechanism for controlling the rotation angle of the pressing head 14 using the stopper 17 has been described. However, the mechanism is not limited to this as long as the mechanism can fix the pressing head 14 at a predetermined rotation angle. Never happen. For example, a stopper 17 extending in the vertical direction may be used, or the length of the stopper 17 may be adjustable, and the rotation angle of the pressing head 14 may be appropriately fixed at an arbitrary angle. The stopper 17 may be provided on either the main body 11 or the pressing head 14.

  Moreover, the form which controls rotation of the press head 14 to arbitrary angles by controlling drive devices, such as a motor which rotates the press head 14, may be sufficient.

  Although a preferable peeling angle varies depending on the material of the separator 31 and the sheet-like adhesive material 32, the rotation angle of the pressing head 14 is fixed to an angle suitable for each material by the rotation angle control mechanism in the present embodiment. Various separators 31 can be peeled off.

  In addition, a suction mechanism may be provided in order to securely hold the separator 31 between the head surface of the pressing head 14 and the clamp head 15b and confirm whether or not the separator 31 has been peeled off.

  FIG. 16 is a partially enlarged view of the cross section of the head surface of the pressing head 14 and the clamp head 15b.

  Inside the pressing head 14, a suction path 14a having an opening on the head surface is formed. The upper part of the suction path 14a is connected to a vacuum device (not shown) via a hose or the like.

  Further, a through hole 15c is formed in the clamp head 15b at a position corresponding to the suction path 14a, that is, on a straight line of the suction path 14a.

  When the vacuum device is operated with the edge of the separator 31 held between the head surface of the pressing head 14 and the clamp head 15b, the opening of the suction path 14a is blocked by the separator 31, as shown in FIG. Therefore, the inside of the suction path 14a is in a vacuum state. In this way, when the vacuum state is reached, it can be confirmed that the separator 31 is securely held between the head surface of the pressing head 14 and the clamp head 15b by the operation of a sensor (not shown) that detects the vacuum state. That is, it can be confirmed that the separator 31 has been reliably peeled off.

  On the other hand, when the separator 31 is not sandwiched, outside air is permanently sucked from the through hole 15c formed in the clamp head 15b, and the suction path 14a is not in a vacuum state. In this case, since the sensor for detecting the vacuum state does not operate, the separator 31 is not sandwiched between the head surface of the pressing head 14 and the clamp head 15b, that is, the separator 31 cannot be peeled off. I can confirm.

  Thereby, since it is easily understood whether or not the separation of the separator 31 is insufficient, that is, a defective product is generated, it is possible to suppress the inadvertent induction of the defective product. Note that whether or not the suction path 14a is evacuated may be determined using a known control device or the like (not shown). Whether or not the separator 31 is held may be determined at any timing during the peeling operation.
