- the load cell 39 measures the tension, and in order to maintain the predetermined tension, the feeding head 49 is lowered obliquely downward using the sticking angle maintaining means 37. That is, the load cell 39 is controlled to measure the tension and issue a command to the pair of single-axis robots 46 so as to obtain a predetermined tension based on the data.
- the feeding head 49 gradually descends along the inclination angle of the guide 45 and the single-axis robot 46 (see FIG. 1), and thereby, the gap between the tip of the peel plate 22 and the pressing roller 14 is increased. Even if the length of the adhesive sheet S is shortened, the sticking angle ⁇ is always kept constant.
- the feeding head 49 is lowered while measuring the tension of the adhesive sheet S by the load cell 39, so that the sticking angle ⁇ is maintained as a result.
- Force to be applied The descending control of the feeding head 49 can omit the load cell 39. That is, as shown in FIG. 4 (A), the position of the lowest point of the pressure roller 14 and the initial tip position when the peel plate 22 is pasted are PI and P2, respectively, and the adhesive sheet S is pasted.
- the tip position of the peel plate is P3 and the application angle of the corners P2, PI, P3 is ⁇
- the peel plate moves as the distance between the points P1, P3 decreases as the pressing roller 14 moves by the single-axis robot 60.
- the feeding head 49 constituting the pasting angle maintaining means 37 is moved down along the guide bar 45 so that the height of 22, that is, the distance between the points P2 and P3 is shortened, so that the pasting angle ⁇ is always maintained.
- Synchronous control of axis robots 46 and 60 You can also The amount of movement of the feeding head 49 can be easily derived by a trigonometric function. As described above, by maintaining the sticking angle ⁇ constant based on the detection of the moving distance of the pressing roller 14, the same action and effect as the tension control using the load cell 39 can be produced. These controls can be selectively employed.
- the cutter 15 descends and cuts the adhesive sheet S along the outer periphery of Ueno and W. After that, the cutter 15 rises and returns to the initial position (see Fig. 1). At this time, the tip of the peel plate 22 is located in the vicinity of the left end of the UE and W, so that the adhesive sheet region where the tip position force of the peel plate 22 also exists on the left side can be used as the region to be bonded to the next wafer W. It is possible to use the adhesive sheet S without wasting it.
- the upper surface height of the outer table 51 can be adjusted according to the thickness of the adhesive sheet S to optimize the adhesion pressure, while the thickness of the wafer W is reduced. If changed, the inner table 52 can be adjusted by its own height, which provides the effect that the adhesive sheet S can be applied with high precision by the optimum pressing force of the pressing roller 14. .
- the present invention can also be applied to a configuration in which a sheet or film is attached to a plate-like member other than the wafer.
- the table 13 can also adopt a configuration that can rotate in a plane.
- the adhesive sheet S can be cut without rotating the cutter 15 side.
