JP 2008-102226 A JP 2006-199325 A

  In the film sticking apparatus of Patent Document 1, the film support is driven to rotate by being driven at the time of peeling and sticking of the film. Further, the film supporting means or the panel holding means is also moved linearly by applying power. It is very difficult to control the film support so as to rotate and synchronize with the speed of the linear motion of the film support means or the like, and there is a possibility that a shift occurs without being accurately synchronized. If a shift occurs when the film is peeled off, the film cannot be held at a predetermined position of the film support, and the film cannot be stuck at a predetermined position of the panel. Further, even when the film can be held at a predetermined position of the film support, the film cannot be attached to the predetermined position of the panel if a shift occurs when the film is applied. Thus, there exists a difficulty that it is difficult to stick a film on a panel accurately.

  The sheet material sticking device disclosed in Patent Document 2 has the following problems. First, the center of gravity of the arc head is away from directly below the center of rotation, and the center of gravity of the arc head changes depending on the rotation angle of the arc head, so that the force required for rotation changes due to gravity. That is, complicated control is required so that the propulsive force of the arc head is reduced at the beginning of the pasting, while the propulsive force of the arc head is increased at the end of the pasting.

  In addition, in the arc head, when a long sheet is stuck, a large arc head is required and the entire apparatus is increased in size. Furthermore, if the radius of the arc head increases, an increase in contact area at the time of peeling and sticking cannot be avoided, and the pressure applied at the time of sticking becomes small.

  Further, since the radius of curvature of the arc is not uniform and is a complicated shape, high machining accuracy is required for machining the arc head, and the manufacturing cost of the apparatus becomes high.

  This invention is made | formed in view of the said matter, The place made into the objective is providing the sticking apparatus which can stick a sheet | seat material to a workpiece | work with high precision.

The sticking device according to the present invention comprises:
In the sheet material sticking device that peels the sheet material from the separator and sticks it to the workpiece,
An adhesive layer is arranged on the outer peripheral surface of the cylindrical body, and a pasting head capable of switching between rotation drive and free rotation;

The sheet material transport means freely rotates the pasting head by feeding the sheet material, peels the sheet material from the separator, and causes the adhesive layer to adhere and hold the sheet material,
The sticking head moves onto the work, the sticking head presses the sheet material against the work, and the sticking head freely rotates with the relative movement between the sticking head support part and the work placing table. Affixing a sheet material on the workpiece;
It is characterized by that.

  Further, the belt-like adhesive material layer may be wound around the outer peripheral surface of the cylindrical body, and both end portions of the adhesive material layer may be separated to form a recess between the both end portions.

  Moreover, a part of outer peripheral surface of the cylindrical body may be cut out along the rotation axis direction of the sticking head.

  Moreover, it is preferable that the said recessed part is formed with the central angle of 30 degrees-90 degrees centering | focusing on the rotating shaft of the said sticking head.

  In the sticking apparatus according to the present invention, when the sheet material is peeled off, the sticking head pressed against the sheet material freely rotates as the sheet material is fed by the sheet material transporting means, and peels and holds the sheet material. In addition, when the sheet material is applied to the workpiece, the application head rotates freely with the relative movement of the workpiece mounting table with respect to the axis of the application head, and the sheet material is applied to the workpiece. Since the sheet material is held at a predetermined position of the sticking head, the sheet material can be stuck to the work with high accuracy.

It is a perspective view of another sheet material. It is a perspective view which shows the state by which the sheet | seat material was affixed on the box-shaped workpiece. It is operation | movement explanatory drawing which shows the mode of the sticking of the sheet material to a box-shaped workpiece.

  The sticking apparatus according to the present embodiment will be described with reference to the drawings. As shown in the front view of FIG. 1 and the plan view of FIG. 2, the sticking device 1 includes a sticking head 10, an adhesive material layer 12, a slide rail 20, a slider 21, a lifting cylinder 22, a table 30, A peeling edge 31, a feed roller 33, a take-up roller 34, a work mounting table 40, and a control unit 70 are provided. In FIG. 2, the slide rail 20, the slider 21, and the elevating cylinder 22 are omitted.

  As shown in FIG. 3, the affixing device 1 peels off the sheet material 50 from the separator 51 and prepares the sheet material 50 prepared by having the separator 51 adhered to the adhesive surface of the sheet material 50. It is a device to stick.

  As shown in the perspective view of FIG. 4, the sticking head 10 has a recess 11 in which a part of a cylindrical outer peripheral surface is cut out. And the adhesive material layer 12 is installed in the outer peripheral surface of the sticking head 10 except the recessed part 11. As shown in FIG. The recess 11 is formed by being cut out in the rotation axis direction with a predetermined width in the circumferential direction of the sticking head 10. In addition, for easy explanation, the side that appears in the order of the end and the circumferential surface when rotating the sticking head 10 at the time of peeling the sheet material 50 for the two ends of the recess 11 is the front end 11a, The side that appears in order of the peripheral surface and the end is defined as the rear end 11b.

  The affixing head 10 is installed on the elevating cylinder 22 so as to be rotatable about a rotation axis. The pasting head 10 can be switched between rotation driving by drive transmission from a drive source such as a servo motor and free rotation by releasing drive transmission from the driving source.

  Switching between rotational driving and free rotation is performed by switching means such as an electromagnetic clutch (not shown). The electromagnetic clutch directly or indirectly connects the rotating shaft of the servo motor and the pasting head 10 when energized. As a result, the power of the drive source is transmitted to the sticking head 10, and the sticking head 10 is rotationally driven. On the other hand, when the power to the electromagnetic clutch is not energized, the connection between the rotating shaft of the servo motor and the pasting head 10 is released, the power of the drive source is not transmitted to the pasting head 10, and the pasting head 10 rotates freely. It becomes possible.

  In addition, the switching means between the rotational drive and the free rotation of the sticking head 10 is not limited to the above-described electromagnetic clutch, and various mechanisms capable of switching between the rotational drive and the free rotation may be used. For example, a rotary shaft such as a servo motor is connected to the pasting head 10, and the pasting head 10 is driven to rotate when power is supplied to the servo motor, and the rotary shaft itself such as the servo motor can freely rotate when power is not supplied. Thus, the configuration may be such that the sticking head 10 can freely rotate.

  The adhesive material layer 12 installed on the outer peripheral surface of the sticking head 10 is formed of a material such as adhesive rubber having a thickness of 1 to 5 mm, for example. The width of the adhesive layer 12 (the length in the X-axis direction and the length in the rotation axis direction) is at least larger than the width of the sheet material 50 and the workpiece 60 (the length in the X-axis direction and the length in the rotation axis direction). Set long. The adhesive material layer 12 is installed on the outer peripheral surface of the sticking head 10 with, for example, a double-sided tape or an adhesive. The adhesive material layer 12 has an adhesive force stronger than the adhesive force between the sheet material 50 and the separator 51 and weaker than the adhesive force between the sheet material 50 and the workpiece 60. Accordingly, when the sheet material 50 is peeled off, the sheet material 50 is held on the surface of the adhesive material layer 12, and when being applied to the work 60, the sheet material 50 is peeled off from the adhesive material layer 12 and attached to the work 60. The

  In addition, a sensor (not shown) or a camera (not shown) that detects the rotation angle of the sticking head 10 and the position in the Y-axis direction is installed.

  The lifting cylinder 22 is a device that suspends and supports the pasting head 10 and lifts and lowers the pasting head 10. Any lifting cylinder 22 may be used as long as it can raise and lower the pasting head 10, such as a pneumatic cylinder, a hydraulic cylinder, and a mechanical cylinder. The elevating cylinder 22 is driven by a control operation by a drive source such as a servo motor (not shown), and raises and lowers the pasting head 10 in the Z-axis direction.

  The slider 21 moves linearly on the slide rail 20 in the Y-axis direction and moves the sticking head 10 by a control operation by a drive source such as a servo motor (not shown). The slider 21 reciprocates so as to be positioned with high accuracy under the control of the control unit 70.

  The table 30 is a flat table on which the peeling tape 52 is placed and the sheet material 50 is placed, and the sheet material 50 is peeled from the separator 51.

  An acute-angled peeling edge 31 is provided at the tip portion of the table 30, and the peeling tape 52 is folded at an acute angle at the peeling edge 31, so that the sheet material 50 can be easily peeled from the separator 51.

  The feed roller 33 is rotated by a control operation by a drive source such as a servo motor. The feed roller 33 functions as a conveying means for the sheet material 50 placed on the peeling tape 52. The peeling tape 52 is sandwiched between the feeding roller 33 and the guide roller 32, and the peeling tape 52 and the sheet material 50 are moved by the rotational driving of the feeding roller 33.

  The winding roller 34 is a device that winds and collects the peeling tape 52. The take-up roller 34 also takes up the separator 51 attached to the release tape 52 together with the release tape 52. The winding roller 34 is rotationally driven by a control operation by a drive source such as a servo motor.

  The workpiece mounting table 40 is a table on which the workpiece 60 is mounted on the upper surface. The work mounting table 40 is located on the straight line of the table 30.

  The control unit 70 switches between the rotation driving and free rotation of the sticking head 10, the control of the rotation angle, the reciprocation of the slider 21, the reciprocation of the elevating cylinder 22, the rotation drive of the feed roller 33, the rotation drive of the take-up roller 34, etc. Control of driving of each device is performed.

  Then, operation | movement of the sticking apparatus 1 is demonstrated. First, peeling of the sheet material 50 will be described. Each operation in the following description is performed based on a command from the control unit 70. In addition, an electromagnetic clutch will be described as an example of the rotation driving and free rotation switching means of the sticking head 10.

  First, the peeling operation of the sheet material 50 will be described. The peeling tape 52 has its adhesive surface facing the opposite side of the table 30, is folded back at the peeling edge 31, and passes between the feed roller 33 and the guide roller 32 so that the tip is fixed to the take-up roller 34. It is set. The sheet material 50 is placed on the release tape 52. The sheet material 50 is placed so that the separator 51 faces the adhesive surface of the peeling tape 52. The sheet material 50 is placed by a sheet material arranging unit (not shown). The sheet material placement unit places the sheet material 50 at a constant interval in the Y-axis direction. A known apparatus can be used as the sheet material arranging means.

  After the sheet material 50 is placed, the sheet material 50 is conveyed by driving the feed roller 33. As shown in FIG. 5A, after the leading end of the sheet material 50 has moved to the peeling position, the driving of the feed roller 34 is stopped.

  The sticking head 10 is moved by driving the slider 21. When the rotating shaft of the sticking head 10 reaches the peeling position, the driving of the slider 21 is stopped. Further, the electromagnetic clutch is energized, and the sticking head 10 is adjusted to a predetermined rotation angle. Specifically, as shown in FIG. 5A, the length of the sheet material 50 in the feeding direction (the length in the Y-axis direction) Ls and the rear end portion from the lower end portion of the peeling position of the pasting head 10. The outer peripheral length Lh up to 11b is adjusted to be equal.

  Thereafter, as shown in FIG. 5B, the sticking head 10 is lowered by driving the elevating cylinder 22 and presses the sheet material 50 through the adhesive material layer 12. The pasting head 10 is in a state where the electromagnetic clutch is energized until the sheet material 50 is pressed, so that the pasting head 10 does not rotate freely before the pasting head 10 presses the sheet material 50 during lowering. Be controlled. And after the sticking head 10 presses the sheet | seat material 50, electricity supply of an electromagnetic clutch is stopped and the sticking head 10 will be in the state which can rotate freely.

  After the sticking head 10 presses the sheet material 50, as shown in FIG. 6A, the feed roller 33 is driven, the peeling tape 52 is folded back at an acute angle at the peeling edge 31, and the feed roller 33 and the guide roller 32 are driven. Is wound around the take-up roller 34. As the release tape 52 moves, the sheet material 50 moves, and the application head 10 rotates following the movement of the sheet material 50. Then, the sheet material 50 is adhesively held on the adhesive material layer 12, and the sheet material 50 is peeled from the separator 51.

  Then, as shown in FIG. 6B, after the peeling tape 52 is wound up until the rear end of the sheet material 50 reaches the peeling position or exceeds the peeling position, the driving of the feed roller 33 is stopped. The Then, the sticking head 10 is raised, and the sheet material 50 is completely peeled from the separator 51. In addition, before the feed roller 33 stops and the sticking head 10 moves up, the electromagnetic clutch is energized, and the sticking head 10 becomes in a state where it cannot freely rotate. Thereby, even if the sticking head 10 is raised, the rotational position does not change.

  Next, the sticking operation of the sheet material 50 will be described. The sheet material 50 held by the sticking head 10 is moved onto the work 60 placed on the work placing table 40 by driving the slider 21. More specifically, the rotating shaft of the sticking head 10 moves to the sticking start point position.

  Then, as shown in FIG. 7A, the sticking head 10 is lowered by driving the elevating cylinder 22 and presses the rear end portion of the work 60. After the sticking head 10 presses the workpiece 60 via the adhesive material layer 12 and the sheet material 50, the energization of the electromagnetic clutch is stopped, and the sticking head 10 is in a freely rotatable state.

  Then, as shown in FIG. 7B, the slider 21 moves linearly. Since the sticking head 10 is in a freely rotatable state, the sticking head 10 follows the linear movement of the slider 21 and the sticking head 10 rotates on the work 60. Since the adhesive force between the sheet material 50 and the adhesive material layer 12 is set to be weaker than the adhesive force between the sheet material 50 and the workpiece 60, the sheet material 50 is adhered to the workpiece 60 as the pasting head 10 rotates. go.

  Then, as shown in FIG. 7C, when the rotation axis of the sticking head 10 moves to the sticking end point position or beyond the sticking end point position, the sticking of the sheet material 50 to the workpiece 60 is completed.

  As described above, when the sheet material 50 is peeled from the separator 51, the sticking head 10 rotates freely with the movement of the sheet material 50 driven by the feed roller 34 with the rotation shaft as a support shaft. For this reason, when the sheet material 50 is peeled off, the moving speed of the sheet material 50 and the rotational speed of the sticking head 10 are automatically synchronized. Tension is not applied to the sheet material 50 due to a mismatch between the moving speed of the sheet material 50 and the rotation speed of the sticking head 10, scratches on the sheet material 50 due to the tension or the like, and adhesion of the adhesive material layer 12 to a predetermined position. There is an advantage that the displacement of the holding does not occur.

  In addition, when the sheet material 50 is applied to the workpiece 60, the application head 10 freely rotates as the rotation shaft moves, and the sheet material 50 is applied to the workpiece 60. 50 shifts do not occur.

  In addition, the sheet material 50 is held on the adhesive material layer 12, and the adhesive material layer 12 has no adsorption hole. For this reason, since there is no formation of a recess in the sheet material 50 due to adsorption, no bubbles are formed between the sheet material 50 and the workpiece 60 when the workpiece 60 is adhered, and the sheet material 50 can be adhered neatly.

  The sticking head 10 has a substantially cylindrical shape, and the pressure during pressing increases. Since the pressure is high, a small cylinder having a weak force can be used as the lifting cylinder 22 for pressing the sticking head 10. Moreover, the rotation center of a drive source such as a servo motor can be made the same as the rotation center of the pasting head 10, and a small drive source with weak force can be used. Moreover, the sticking head 10 is obtained by cutting out a part of a cylindrical body having a constant curvature radius to form a recess, and does not require high processing accuracy like the arc head of Patent Document 2, and the manufacturing cost is low. It leads to reduction. Furthermore, it is possible to attach a long sheet without increasing the size as in the arc head of Patent Document 2. In addition, the substantially cylindrical sticking head 10 can be rotated 360 ° and does not interfere with other mechanisms, so that the mechanical limit and the hard limit necessary for the arc head of Patent Document 2 are not necessary. From the above, it is possible to reduce the size of the sticking device 1 and reduce the manufacturing cost.

  Further, since the rear end portion 11b of the concave portion 11 is controlled so as to coincide with the rear end portion of the sheet material 50 in the feeding direction, when the sheet material 50 is peeled, the moving amount of the peeling tape by the feed roller 34 is reduced. Even if it becomes larger, the adhesion between the adhesive material layer 12 and the peeling tape 52 is suppressed. If the adhesive material layer 12 adheres to the peeling tape 52, the adhesive material layer 12 is deteriorated, the replacement cycle of the adhesive material layer 12 is accelerated, and the running cost is increased. However, in this embodiment, since the sticking head 10 in which the concave portion 11 is formed is used, deterioration of the adhesive material layer 12 can be suppressed, and the replacement cycle of the adhesive material layer 12 can be lengthened. It leads to reduction.

  In the above description, the mode in which the peeling of the sheet material 50 is just completed at the rear end portion 11b of the sticking head 10 has been described, but the present invention is not limited to this. Even if the sheet material 50 is held in the entire region from the front end 11a to the rear end 11b of the sticking head 10, it is held on a part of the rear end 11b from the front end 11a of the sticking head 10. It may be a form.

  Further, before pressing the sheet material 50 against the workpiece 60, the sticking head 10 is rotated to bring the sheet material 50 into the workpiece 60 in the state shown in FIG. 8A (starting state when the sheet material 50 is peeled off). As shown in FIGS. 8B and 8C, the slider 21 may be moved and pasted while the pasting head 10 is freely rotatable.

  As shown in FIG. 9 (B), the concave portion 11 of the sticking head 10 is not cut to the vicinity of the rotation axis, as shown in FIG. 9 (A). It may be a form cut out by a predetermined depth in the direction. There is no particular limitation on the angle θ of the recess 11 of the sticking head 10 (the angle θ formed by the front end 11a, the rotation shaft of the sticking head 10 and the rear end 11b), but the sheet material 50 is excessively removed at the time of peeling. Even when it is sent, it is preferable that the front end 11a is set so as to be separated from the rear end 11b so as not to contact the peeling tape 52. On the other hand, if θ is too large, the circumferential length of the sticking head 10 becomes short, and it becomes impossible to stick a long sheet. In view of the above, the angle θ of the recess is preferably 30 ° to 90 °.

  Further, as shown in FIG. 9C, a belt-like adhesive material layer 12 is wound around a cylindrical sticking head 10 in which notches are not formed, and both end portions of the adhesive material layer 12 are separated. The recess 11 may be formed by being arranged. Since the adhesive material layer 12 has a sufficient thickness, the front end 11a can be prevented from coming into contact with the peeling tape 52 even when the sheet material 50 is fed excessively at the time of peeling.

  In the above description, when the sheet material 50 is attached to the workpiece 60, the workpiece mounting table 40 is fixed and the slider 21 is linearly moved. However, the slider 21 is fixed and the workpiece mounting table 40 is linearly moved. There may be. By the relative movement between the rotation axis of the sticking head 10 and the work mounting table 40, the sheet material 50 can be stuck to the work 60 in the same manner as described above.

  Moreover, although the example which peels from the separator 51 using the peeling tape 52 about the sheet-like sheet material 50 was demonstrated above, as shown in FIG. 10, the several sheet material 50 is set to the strip | belt-shaped separator 51 at predetermined intervals. The thing of the form which was stuck and hold | maintained and formed in the shape of a roll may be sufficient. In this case, the peeling tape 52 is not necessary, and the sheet material 50 is peeled in the same manner as described above by fixing the end of the strip-shaped separator 51 in the longitudinal direction to the winding roller 34 and winding the separator 51. Can do.

  Moreover, as long as the sheet | seat material 50 is a thin film shape which can be bent and deformed according to the surrounding surface of the sticking head 10, various things, such as functional films, such as a label, a protective film, a decoration film, or a polarizing film, can be used. There is no particular limitation. The shape of the sheet material 50 may be any shape such as a circle, a polygon, and an ellipse in addition to a rectangle.

  Also, the workpiece 60 can be attached to various things such as a liquid crystal panel, glass, various substrates, and a box, and is not particularly limited.

  Moreover, since the sticking head 10 has the recessed part 11, it has the advantage that the sheet | seat material 50 can be stuck to the bottom part of the recessed part of a workpiece | work, for example, the box-shaped workpiece | work 60 shown in FIG.

  The sticking head 10 set so that the length of the bottom surface of the workpiece 60 and the length of the adhesive material layer 12 are substantially the same length is used. That is, when the thickness of the adhesive material layer 12 and the sheet material 50 is ignored, the circumferential length excluding the concave portion 11 of the sticking head 10 and the lengths of the adhesive material layer 12 and the bottom surface of the work 60 are substantially equal. Then, as described above, the sheet material 50 is peeled from the separator 51, and the sheet material 50 is adhesively held on the adhesive material layer 12.

  Then, as shown in FIG. 12A, the elevating cylinder 22 is driven to press the sticking head 10 against the end of the bottom surface of the work 60.

  As shown in FIGS. 12B and 12C, by driving the slider 21, the sticking head 10 freely rotates and the sheet material 50 is stuck on the bottom surface of the work 60.

  In a cylindrical sticking head having no recess 11, the sticking head does not contact the bottom end of the work 60, and the sheet material 50 cannot be stuck to the end. However, in this embodiment, the sticking head 10 has the recess 11, and the recess 11 is controlled so as to sandwich the wall of the box-shaped workpiece 60, so that the bottom of the box-shaped workpiece 60 is end to end. A sheet material 50 can be attached.

  In addition, in said embodiment, although the sticking head 10 in which the recessed part 11 was formed was demonstrated, the cylindrical sticking head 10 in which the recessed part 11 is not formed may be sufficient. In this case, there is a possibility that the adhesive material layer 12 may adhere to the peeling tape 52, and the sheet material 50 cannot be pasted from the end to the end of the bottom surface of the box-shaped workpiece 60. Control that synchronizes the feeding speed with the pasting head 10 and the rotational speed is unnecessary, and there is an advantage that high-precision pasting is possible.
