Description

DETAILED DESCRIPTION OF THE INVENTION Field of Industrial Application The present invention relates to a coating device for forming a protective film on the surface of a disk used for recording and playing back document files, still images, and videos.

Conventional configuration and problems Conventionally, the processes of applying the coating liquid, adjusting the coating film thickness, and drying were performed using two devices: a coating device and a drying device. There were problems such as scratches on the coated film surface and the adhesion of dust when the material to be coated was installed in the drying device.

OBJECTS OF THE INVENTION The present invention solves the above-mentioned conventional drawbacks, and aims to maintain high quality by completing the entire process from coating to drying without attaching or detaching the coated material.

Structure of the Invention The present invention includes a rotating shaft located approximately in the center of a main body room, which holds and rotates a material to be coated, and a door provided in the main body room to supply the material to be coated, and the material to be coated is supplied to the rotating shaft and held on the rotating shaft. a first station that applies a coating liquid to the material to be coated, a second station that applies a coating liquid to the material to be coated by movable a liquid storage tank equipped with a filtration device to a position of the material to be coated; a third station provided with a scattering cover configured to be movable so as to cover the material to be coated when rotating the coating material around the rotation axis to scatter excess coating liquid; a fourth station for accommodating the material to be coated in a drying chamber equipped with a shutter and a drying device and drying and curing the coating liquid; The coating device is characterized in that the material to be coated moves sequentially through the first to fourth stations by rotating a pivoting arm that integrally holds the material to be coated and the rotating shaft. After fixing the material to the rotating shaft,
It is possible to continuously apply the coating liquid, adjust the coating thickness using centrifugal force, and dry and harden the coating, making it possible to form a high-quality coating layer.

DESCRIPTION OF EMBODIMENTS An embodiment of the present invention will be described below with reference to FIGS. 1 to 6.

In the figure, 1 is a rotating arm, 2 is a filtration device,
3 is a liquid storage tank, 4 is a scattering cover, 5 is a shutter, 6 is a drying device, 7 is a main body room, 8 is a drying room, 9 and 10 are exhaust holes, 11 is a main body room door, 1
2 is a material to be coated, and 101 is a rotating shaft.

In the apparatus having the above configuration, as shown in FIG. 2, the main room door 11 is opened and the material to be coated is
When the liquid storage tank 3 is set on the rotating shaft 101 held by the rotating arm 1, the liquid storage tank 3 rises as shown in FIG. Liquid tank 3
The coating liquid inside is applied to the surface of the material to be coated 12.

Next, the liquid storage tank 3 descends and retreats, then the swing arm 1 swings down and the scattering cover 4 rises as shown in FIG.

In this state, the coated material 12 is rotated at high speed to adjust the coating film thickness.

Next, as shown in FIG.
6, the rotating arm 1 stops at a predetermined position in the drying chamber 8, and the shutter 5 closes.

In this state, the coating liquid applied to the surface of the material to be coated 12 is dried and hardened by the drying device 6, and when the drying and hardening is completed, the shutter 5 is opened and the swing arm 1 is rotated counterclockwise, as shown in FIG. It returns to the indicated position and stops, and then the shutter 5 closes to complete the coating cycle by this apparatus.

Effects of the Invention As described above, the present invention enables the material to be coated to move sequentially through the entire process from application of the coating liquid to drying and curing by the rotation of the rotating arm, and the process is completed without attaching or detaching the material to be coated between processes. This has the effect of forming a high-quality coating layer that is free from scratches and dust adhesion.
