It is moved up and down by 1 and is disposed below the superposition table 910. A through hole is formed in the upper push-over stacking table 910 for passing the other-side disc pressing portion 930.

That is, the other side disk holding device 900B
While the other side disk 3B is passed through the center pin 915, the other side disk 3B is moved by the suction portion 920.
The peripheral end portion 3Bd is sucked and held, and from this held state, the central portion 3Bc of the other side disk 3B is pressed from below to bend the other side disk 3B in a bowl shape.

Next, the one side disk holding device 900A
Will be described. The one-sided disk holding device 900A

As described above in detail, according to the present invention, when the glue transfer portion is pressed against one side and the other disk by the hemispherical glue transfer portion, the hemispherical top portion is formed. , And crushes radially toward the periphery to come into contact with the other side, whereby the liquid glue can be transferred to the disk. Then, the glue transfer section has a center wheel.
Since the clearance hole is formed, the glue can be transferred from near the center-hole of the disk when the glue is transferred to the disk. As a result, when the two discs are bonded together, the glue that reaches the center-hall close to the two discs firmly and well adheres the two discs.
Also, by supplying liquid glue at a uniform depth to the glue receiving pallet, when the glue is transferred from the glue receiving pallet to the glue transferring section, the glue is transferred to the glue transferring section with a predetermined thickness. It is easy to realize a predetermined glue thickness when glue is transferred from the glue transfer unit to the disk. The glue on the disk is diffused by the glue disk rotating device, so that the thickness of the glue can be made uniform and smooth.

According to the second aspect of the present invention, liquid glue can be supplied onto the disc by the glue supply nozzle, and the liquid glue supplied onto the disc is diffused by the glued disc rotating device. The thickness of the glue can be made uniform and smooth.

According to the third aspect of the invention, the center pin allows the center pin to pass through the center holes of the discs on one side and the other side. This allows
The center-wheel positioning accuracy is good when the above-mentioned one-side and other-side disks are superposed. Further, when the one-sided disk and the other-sided disk are overlapped by the one-sided disk holding device and the other-sided disk holding device, the bending axis of the one-sided disk and the bending axis of the other-sided disk are cross-shaped. Since the discs are superposed in a shape, the one-side and the other-side discs in the bent state can be gradually brought into contact with each other from the center portion to the circumferential end portion of each other. As a result, pressure is applied to the liquid glue between the two discs from the central portion of the disc to the circumferential end portion, and the air contained in the glue can be pushed out. That is, the residual air contained in the liquid glue between the two disks can be reduced, and the thickness of the disk as a product can be accurately obtained.

According to the fourth aspect, the center pin allows the center pin to pass through the center holes of the discs on one side and the other side. This allows
The center-wheel positioning accuracy is good when the above-mentioned one-side and other-side disks are superposed. Furthermore, when the one-sided disk and the other-sided disk are overlapped by the one-sided disk holding device and the other-sided disk holding device, the top of the other-side disk contacts the top of the one-sided disk. Then, the contact can be gradually made from here to the circumferential ends of the one side and the other side disks. As a result, pressure is applied to the liquid glue between the two disks from the center to the circumferential end of the disk, and the air contained in the liquid glue can be pushed out. That is, the residual air contained in the liquid glue between the two disks can be reduced, and the thickness of the disk as a product can be accurately obtained.

According to the fifth aspect, the center pin allows the center pin to pass through the center hole of the stacked discs. This allows
The center-wheel positioning accuracy after superposing the above-mentioned one-side and other-side disks becomes good. Further, when the hemispherical pressing portion presses the pressing portion against the superposed discs, the hemispherical pressing portion comes into contact with the other side while squashing radially toward the peripheral portion from the top portion. As a result, the liquid glue between the two disks is pressed from the central portion of the disks to the circumferential end portion thereof, and the air contained in the glue can be pushed out. That is, the residual air contained in the liquid glue between the two disks can be reduced, and the thickness of the disk as a product can be accurately obtained.
