  However, in the conventional sheet sticking device described in Patent Document 1, the precut device 13 (cutting device) forms a cut without considering the shape of the tip (peeling edge) of the peel plate 26 (peeling device). In order to form the dicing tape T (adhesive sheet), the peeling start edge may be parallel to the peeling edge of the peeling means depending on the shape of the adhesive sheet. In such a case, the adhesive sheet peels off the tip end region including many peeling start edges at once at the peeling edge of the peeling means, so that the adhesive sheet has a force to adhere to the base sheet S (release sheet) in the tip end region. If the rigidity of the tip end region is superior, the conventional sheet sticking apparatus cannot peel the adhesive sheet from the release sheet, resulting in a peeling failure.

  The objective of this invention is providing the sheet sticking apparatus and sticking method which can stick the said adhesive sheet to a to-be-adhered body, without generating peeling defect with a peeling means.

  The present invention employs the configurations described in the claims.

According to the present invention, in consideration of the shape of the peeling edge of the peeling means, the cut is formed so that the peeling start edge of the adhesive sheet is not parallel to the peeling edge, so the adhesive sheet is the peeling edge of the peeling means. A lot of the tip region is not peeled off at once, and the adhesive sheet can be attached to the adherend without causing a peeling failure by the peeling means.
Further, if the moving means includes a displacing means, the adhesive sheet and the adherend can be aligned and the adhesive sheet can be attached to the adherend.
Furthermore, if the displacement means changes the orientation of the adherend based on the detection result of the sheet direction detection means, the adhesive sheet and the adherend are aligned without using labor. Can be affixed to the adherend.

First, with respect to the sheet sticking apparatus 10 in which each member is arranged at an initial position indicated by a solid line in FIG. 1, a user of the sheet sticking apparatus 10 (hereinafter simply referred to as “user”) shows the raw fabric RS in the same figure. After setting as described above, an automatic operation start signal is input to a control means (not shown) via an operation means (not shown) such as an operation panel or a personal computer. Then, the feeding means 20 and the cutting means 30 drive the rotation motors 23A and 31 to feed the original fabric RS, and rotate the cutter roller 32 in synchronization with the feeding of the original fabric RS, so that the adhesive sheet base material ASB The cut CU is formed, and the adhesive sheet AS is formed inside thereof.
In the case of the present embodiment, the planar shape of the adhesive sheet AS is rectangular as shown in FIG. 1B, and the cutting means 30 is from a direction orthogonal to the original fabric guide surface 50 </ b> B of the release plate 50. Considering that the shape of the peeling edge 50A is a straight line in the viewed orthogonal view (hereinafter simply referred to as "orthogonal view"), the peeling start edge ASF of the adhesive sheet AS is not parallel to the peeling edge 50A. A cut CU is formed. Further, when the adhesive sheet AS is fed out together with the original fabric RS, the sheet direction detection unit 40 causes a center line CLA passing through the centers of the two short sides of the adhesive sheet AS, as shown in FIG. The inclination θ1 of the adhesive sheet AS, which is the inclination of the anti-RS feeding direction LD, is detected, and the direction thereof is detected.

  Thereafter, the moving means 70 drives the rotation motor 73 and the adherend direction detecting means 75, and the adherence is an inclination between the center line CLW passing through the centers of the two short sides of the adherend WK and the sticking direction SD. The support table 74 is rotated so that the inclination θ2 of the body WK becomes the same angle as the inclination θ1 of the adhesive sheet AS. Then, the moving means 70 drives the linear motor 71 to move the support table 74 to the left, and the fact that the adherend WK has reached a predetermined position is an imaging means such as a camera or a projector, an optical sensor or a sound wave sensor. When the adherend detection means (not shown) such as various sensors detects the detection means, the feeding means 20 and the cutting means 30 drive the rotation motors 23A and 31 to form the adhesive sheet AS on the adhesive sheet base material ASB. The raw material RS is fed out according to the conveyance speed of the landing body WK. As a result, the adhesive sheet AS is peeled off from the release sheet RL at the release edge 50A of the release plate 50 by the pressing roller 60 as shown by a two-dot chain line in FIG. 1 (A) and FIG. Affixed by pressing on the upper surface.

  After the entire adhesive sheet AS is affixed to the adherend WK, when a tip detection means (not shown) detects that the next adhesive sheet AS has been peeled from the release sheet RL by a predetermined length at the release edge 50A of the release plate 50, The feeding means 20 and the cutting means 30 stop driving the rotation motors 23A, 31 and enter the standby state again. Products (not shown) such as imaging means such as cameras and projectors, various sensors such as optical sensors and acoustic sensors, etc., indicate that the adherend WK to which the entire adhesive sheet AS has been attached has reached a predetermined position on the left side of the pressing roller 60. When the detection means detects, the moving means 70 stops driving the linear motor 71 and the decompression means (not shown). Thereafter, after the user or a conveying means (not shown) conveys the adherend WK to which the adhesive sheet AS is attached to the next step, the moving means 70 drives each driving machine to return the support table 74 to the initial position. Thereafter, the same operation as described above is repeated.
