- the system 24 6 enters above the spin table 35 2, its height is set to 200 mm, as shown at point A in the figure. Then, it descends from the position of point A to the automatic operation standby position (100 mm) indicated by point B in 2 seconds, and then from the position of point B to the contact position with stamper 280 indicated by point C (5 mm ) Until 2 seconds later.
- the bonding head 356 is brought into contact with the stamper 280 in this way, the descent speed is reduced, and the descent is performed at a constant speed to the stamper bonding height shown at the point E.
- the stamper 280 located in the middle of the hollow rubber member 370 descends together with the bonding head 356, the stamper 280 is at the height of point D (1 mm). Centering is performed by the hollow rubber member 370 in the same manner as the disk 278.
- the height of the point D can be set arbitrarily according to the specifications of the stamper 280 and other circumstances, and the height is set to the diameter of the expanding member 37 located inside the hollow rubber member 37. It can be set freely according to the degree of expansion of 2. If the height at which the stamper 280 is centered is stored in advance in the control means (1 mm in this embodiment), the control is performed when the bonding head 356 reaches the point D.
- the means activates the stamper suction means and causes the stamper mounting surface 384 to suck the stamper 280. Note that the time from point C to point D is set to 4 seconds.
- the stamper 280 is centered by the hollow rubber member 370 as described above. Then, the stamper 280 is sucked, and the stamper 280 is lowered to the preset bonding height shown at the point E in the figure while maintaining the centering position of the stamper 280 (while keeping the position in the radial direction fixed). Just do it.
- the bonding height (so-called clearance) of the stamper 280 to the disc 278 is as follows. It is set arbitrarily between the range of 100 ⁇ m to several 100 ⁇ m.
- the bonding head 356 reaches point E and the bonding height of the stamper 280 to the disk 278 is set, the bonding head is moved from point F to point G. Raise c 3 5 6.
- the control means stops the stamper suction means so that the bonding head 356 and the stamper 280 can be easily separated from each other. .
- the bonding table 350 is rotated 180 degrees, and the bonded disk 278 is rotated.
- the stamper 280 and the spinner table 350 are moved to the temporary UV irradiation unit 360.
- the temporary UV irradiating section 360 the bonded disc 2 780 and the stamper 280 are rotated, and the centrifugal force causes the ultraviolet curable resin to expand outward from the inner edge of the disc.
- the space between the disk 278 and the stamper 280 is filled with an ultraviolet curable resin.
- the first UV irradiator 358 is operated to irradiate the ultraviolet curable resin with the ultraviolet light via the stamper 280, thereby curing the ultraviolet curable resin until the thickness dimension does not change. (So-called temporary curing step).
- the bonding table 350 is again rotated by 180 degrees, and the bonded disk 278 and the stamper 280 are rotated by a spin rate. Together with the disc 3 780 and the stamper bonding section 2 36, and then, using the first transfer arm 2 46, grasp the disc 2 780 and the stamper 280, and The disk 278 and the stamper 280 are conveyed to the UV irradiating section 238 by the rotation of the transfer arm 246, and the UV curable resin is fully cured by the UV irradiating section 238. What should I do?
- one disk 27 8 (and stamper 28 0) shows that it passes through the stamper bonding part, but the actual operation is that three arms provided on the first transfer arm 246 work simultaneously, and a plurality of discs 2 7 8 (And stamper 280) pass through the stamper lamination.
- the pressing wall 37 4 and the center pin 37 6 are provided inside the hollow rubber member 37 0 to increase the diameter of the hollow rubber member 37 0.
- the present invention is not limited to the form, and another form may be used.
- FIG. 13 is an explanatory sectional view showing another embodiment of the centering member. Since the structure other than the centering member is the same as that of the above-described spinner table 352, the same parts are given the same part numbers for description.
- a bag-shaped hollow rubber member 406 is attached so as to protrude from the central portion of the spinner table 352.
- a pair of air pipes 408 connected to the hollow rubber member 406 is provided below the hollow rubber member 406, and the other end of the air pipe 408 is It is connected to pressure supply means (not shown). If the pressure supply means is connected to the bag-like hollow rubber member 406 via the air pipe in this way, the diameter of the hollow rubber member 406 can be increased by introducing air into the hollow rubber member 406. In addition, if air is sucked from the inside of the hollow rubber member 406, the outer diameter of the hollow rubber member 406 can be reduced, and the centering and removal of the disk 278 can be easily performed.
- the stamper is superimposed on the disk, and thereafter, the stamper is lowered toward the disk by pressing the bonding head. Then, after the stamper is centered by fitting with the centering member, the stamper is sucked by the bonding head. If the clearance of the stamper with respect to the disc is set by lowering the bonding head in this way, the disc and the stamper can be centered, and the disc and the stamper can be fixed without tilting and warping. It becomes possible to perform matching.
