  However, in the method in which the separator is peeled off by vacuum adsorption, there is a risk that the holding by the vacuum suction may be released due to disturbances such as the surface state of the separator and the force at the time of peeling.

  On the other hand, in the method of peeling while mechanically clamping the separator using the claw portion, it is necessary to insert the claw portion into a thin region corresponding to the thickness of the double-sided tape. For this reason, the size (thickness) of the nail portion must be reduced. Further, since the separator is made of a thin sheet or film, it is often curled rather than planar. As shown in FIG. 6D, in the double-sided tape 200, when the separators 240 and 260 attached on both sides are curled inward to form a curled portion 280, the nail portion is designed to be smaller. It is necessary to make the nail part difficult.

However, the present invention is not limited to this, and a double-sided tape is attached to a semiconductor device other than RFID or other products. You can also. Moreover, it is not limited to a double-sided tape, It is applicable also for affixing a single-sided tape.

  In FIG. 1, 120 is a product supply unit. The product supply unit 120 supplies a product such as an RFID to which the double-sided tape is applied by the tape applying apparatus 100 to the inside of the tape applying apparatus 100. Reference numeral 130 denotes a transport device. The transport device 130 sucks the product supplied from the product supply unit 120 and transports the product to the double-sided tape supply unit 140. The double-sided tape supply part 140 supplies the double-sided tape for sticking to a product to the inside of the tape sticking apparatus 100. The double-sided tape supplied from the double-sided tape supply unit 140 is formed of, for example, urethane foam, and a separator (release paper) is pasted on both sides (adhesion side) thereof.

  Reference numeral 150 denotes a tape sticking unit (sticking means). In the tape affixing part 150, the separator attached to one surface (adhesive surface with the product) of the double-sided tape is peeled from the adhesive member by a method as described later. And the double-sided tape is affixed on a product by pressing the surface from which the separator was peeled off and the product conveyed by the conveying device 130. The product to which the double-sided tape is attached is adsorbed by the conveying device 130 and conveyed to the product storage unit 160. Through such processes, the product storage unit 160 stores a product to which a double-sided tape is bonded. The separator is bonded to the other surface of the double-sided tape that is bonded to the product (the surface opposite to the surface that is bonded to the product), and there is no problem of bonding to other products.

  Next, the configuration of the product and the double-sided tape in the present embodiment will be described with reference to FIG. 2A and 2B are schematic views of the product and the double-sided tape. FIG. 2A is a plan view and a front view of the product, FIG. 2B is a plan view and a front view of the double-sided tape, and FIG. FIG. 2D is an enlarged view of a portion surrounded by a dotted line d in FIG. 2B, and a plan view and a front view of the product to which the tape is attached.

  As shown in FIG. 2A, the product 10 of this embodiment is an RFID, for example, and has a substantially square shape in a plan view. The RFID has a semiconductor chip and an antenna mounted therein and is covered with a resin package. As shown in FIG. 2B, the double-sided tape 20 of the present embodiment is made of a cushioning material such as urethane foam, polyethylene foam, foamed polymer, and the like. The double-sided tape 20 has a thickness of, for example, about 1 mm as viewed from the front view, but is not limited thereto. Further, the double-sided tape 20 has a square shape slightly smaller than the product 10 as viewed in a plan view, for example, 5 cm long and 5 cm wide. As shown in FIG. 2D, separators 24 and 26 are attached to both surfaces (adhesive surfaces) of the double-sided tape 20. The separators 24 and 26 are provided with regions (velos 25 and 27) that are not bonded to the bonding surface of the double-sided tape 20. The separators 24 and 26 have a thickness of about 0.1 mm, for example.

  As shown in FIG. 2C, the double-sided tape 20 is affixed to one surface of the product 10 so that the ends of the four sides of the product 10 are slightly exposed when viewed in plan view. However, due to the presence of the tongue 25 in the separator 24, the end (right end) of one side of the product 10 is covered with the tongue 25.

  Next, with reference to FIG.3 and FIG.4, the peeling method which peels a separator from a double-sided tape is demonstrated. FIG. 3 is a configuration diagram of a tape application unit when the separator is peeled from the double-sided tape in the tape application device of the present embodiment. As shown in FIG. 3, a rubber sheet packing 36 (suction plate) is provided on the metal base 30, and the rubber sheet packing 36 is fixed to the metal base 30 by a fixing portion 38. Further, the metal base 30 is formed with a plurality of suction holes 34, and air is sucked from the suction holes 34 by a vacuum pump (not shown). The rubber sheet packing 36 is also formed with suction holes, and the suction holes of the rubber sheet packing 36 and the suction holes of the metal base 30 communicate with each other. The rubber sheet packing 36 may be a porous material. Further, the metal base 30 forms a gently curved surface having a convex shape at the center of the upper surface. For this reason, when the double-sided tape 20 is disposed on the rubber sheet packing 36 with the separators attached on both sides, the double-sided tape 20 is placed on the rubber sheet packing 36 by sucking air from the suction holes 34. It is fixed along the convex shape. As described above, the rubber sheet packing 36, the suction hole 34, and the vacuum pump have the second surface (the lower surface in the drawing) opposite to the first surface (the upper surface in the drawing) to which the separator 24 is attached. ) Constitutes a suction means for vacuum-sucking the double-sided tape. A part (right end portion) of the double-sided tape 20 protrudes from the rubber sheet packing 36 and is disposed on the divided metal portion 32.

  In this embodiment, when the separator 24 is peeled from the double-sided tape 20, first, the whole fixing portion is lowered by a driving source (not shown) and the fixing portion 42 is pressed against the double-sided tape 20. The lower surface of the fixed portion 42 is formed in a lower surface central concave shape in accordance with the upper surface central convex shape of the metal base 30. At this time, the nail | claw part 44 (1st nail | claw part) also descend | falls and presses the separator 24 and the double-sided tape 20 locally. The claw part 44 presses the double-sided tape 20 through the separator 24 in the vicinity of the end of the double-sided tape 20 (upper part of the divided metal part 32). Thus, when the double-sided tape 20 is pressed by the nail | claw part 44, the tongue 25 (overhang | projection part) of the separator 24 will face upward by angle (theta). In this way, the claw portion 44 presses the vicinity of the end portion of the double-sided tape 20 to which the separator 24 is attached from the first surface side, and the tongue 25 of the separator 24 that protrudes outside the double-sided tape 20 (the protruding portion). ) Is configured to launch.

  In this state, the claw portion 48 (second claw portion) connected to the shaft 47 of the air cylinder 46 is moved in the left direction in FIG. 3, so that the claw portion 48 easily hooks the tongue 25 of the separator 24. Can do. When the claw portion 48 moves and comes into contact with the anti-slip rubber 45 (rubber portion), the tongue 25 can be stably sandwiched between the claw portion 48 and the anti-slip rubber 45. As described above, the claw portion 48 is configured to peel the separator 24 from the double-sided tape 20 while mechanically sandwiching the tongue 25 of the separator 24. Specifically, the claw part 48 sandwiches the separator 24 between the claw part 44 and the non-slip rubber 45 provided on the claw part 44, and rises slightly with the claw part 44 (another vertical drive source not shown). After that, the separator 24 is peeled from the double-sided tape 20 by moving in the left end direction.

  Hereafter, the separator peeling method in a present Example is demonstrated concretely with reference to FIG. FIG. 4 is an explanatory diagram of a separator peeling method. First, the claw portion 44 is pressed against the double-sided tape 20 via the separator 24. Thereby, the tongue 25 of the separator 24 faces upward by an angle θ (FIG. 4A).

  At this time, it is preferable to set the pressing position of the claw part 44 (distance from the right end of the double-sided tape 20) to a position having a length of about 2 to 3 times the thickness of the double-sided tape 20. For example, when the thickness of the double-sided tape 20 is 1 mm, the claw portion 44 is set to be pressed at a position of 2 to 3 mm from the right end of the double-sided tape 20. Further, it is preferable that the amount of the claw portion 44 to be pushed downward is set to about 1/2 to 2/3 of the thickness of the double-sided tape 20. When the thickness of the double-sided tape 20 is 1 mm, the claw portion 44 is set so as to push the double-sided tape 20 by 0.5 to 0.7 mm. Thus, the tongue 25 of the separator 24 can be lifted more effectively by appropriately adjusting the pressing position and pressing amount of the claw portion 44 according to the thickness and cushioning properties of the double-sided tape 20 and the material of the separator 24. Can do.

  Further, the claw portion 44 has a most advanced portion that contacts the separator 24, and preferably the length of the most advanced portion in the horizontal direction in the drawing is set to about 0.5 to 1 mm. Moreover, the front-end | tip part including the front-end | tip part has R shape (the front-end | tip part is curled up), and it prevents that the separator 24 (double-sided tape 20) cuts. Similarly to the above, it is necessary to change the shape of the front end part appropriately according to the thickness and cushioning properties of the double-sided tape 20 and the material of the separator 24.

  Next, the claw portion 48 is moved in the direction of the arrow (left direction), and the claw portion 48 is caught under the tongue 25 of the separator 24 and hooked (FIG. 4B). At this time, since the claw part 44 presses the double-sided tape 20 to turn the tongue 25 upward, the claw part 48 can easily hook the tongue 25.

  Subsequently, when the claw portion 48 is further moved in the direction of the arrow, the tongue 25 of the separator 24 is further upward from the angle θ (FIG. 4C), and when the claw portion 48 is further moved, the tongue 25 is separated from the claw portion 48. It is sandwiched between the non-slip rubbers 45 (FIG. 4D). Finally, the claw portion 48 is pressed against the anti-slip rubber 45 (FIG. 4E). Thereby, the tongue 25 of the separator 24 can be securely fixed between the claw portion 48 and the anti-slip rubber 45. In this manner, with the tongue 25 of the separator 24 being fixed with the claw 48 sandwiched between the non-slip rubber 45, the claw 44 is slightly raised so that the claw 44 is separated from the separator 24 (double-sided tape 20). (Another vertical drive source (not shown)). And the separator 24 can be easily peeled from the double-sided tape 20 by moving the nail | claw part 44 and the nail | claw part 48 integrally to the left end direction in a figure.

  Next, with reference to FIG. 5, a method for attaching a double-sided tape to a product will be described. FIG. 5 is an explanatory diagram of a method for attaching a double-sided tape. As shown in FIG. 5A, first, the double-sided tape 20 is placed on the rubber sheet packing 36 formed in a convex shape at the center of the upper surface where the suction holes 34 are formed, and the double-sided tape 20 is evacuated. To securely fix the convex shape at the center of the upper surface. At this time, separators 24 and 26 are attached to both adhesive surfaces of the double-sided tape 20, respectively. In addition, the separators 24 and 26 respectively have tongues 25 and 27 that protrude to the left from the double-sided tape 20. In this state, as shown in FIG. 5B, when the separator 24 (double-sided tape 20) is pressed by the claw portion 44, the tongue 25 of the separator 24 faces upward. In the present embodiment, the separator 26 does not necessarily have to include the tongue 27 protruding outside the double-sided tape 20.

  Subsequently, the separator 24 is peeled from the double-sided tape 20 by using the peeling method described with reference to FIG. Next, as shown in FIG. 5C, the product 10 is placed on the double-sided tape 20 having a convex shape at the center of the upper surface from which the separator 24 is peeled off. The product sticks from the convex shape at the center of the upper surface of the double-sided tape 20, the vacuum pump (not shown) is turned off, the suction is turned off, and the product is brought into contact along the convex shape, so that the double-sided tape 20 is bonded to the product side without air mixing The As described above, the tape attaching unit 150 is configured to attach the double-sided tape 20 to the product on the first surface from which the separator 24 is peeled off.

  At this time, since the upper surface of the rubber sheet packing 36 has a curved surface shape (arc shape), the double-sided tape 20 fixed thereon has a curved surface shape reflecting the shape. Specifically, it has a kamaboko shape that is a curved surface in the left-right direction in the figure, but is a plane in the depth direction in the figure. Thus, the product 10 is affixed to the double-sided tape 20 with the double-sided tape 20 disposed on the rubber sheet packing 36 having a curved shape. Therefore, when the product 10 is affixed to the double-sided tape 20, air can be reliably affixed without air entering between the product 10 and the double-sided tape 20. However, the present embodiment is not limited to this, and the upper surface of the rubber sheet packing 36 may be formed in a spherical shape that is also a curved surface in the depth direction in the drawing. The product in this case can adhere the double-sided tape 20 by moving along the spherical surface.

  As described above, according to this embodiment, it is possible to provide a separator peeling method and a separator peeling device that can easily peel a separator attached to a tape. Moreover, the tape sticking method and tape sticking apparatus which can peel a tape separator easily and can stick a tape to a product can be provided.

  The embodiment of the present invention has been specifically described above. However, the present invention is not limited to the matters described as the above-described embodiments, and can be appropriately changed without departing from the technical idea of the present invention.
