Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to an improvement in a support device for cleaning optical lenses and the like.

Conventional support devices for cleaning optical lenses include:
As shown in Fig. 1, a large number of plastic spheres 2 having a hexagonal cross section are inserted into a stainless steel support rod 1, and three serrated grooves are prepared on the outer peripheral surface. The spacing between the support rods is adjusted to form a V-shape, both ends of which are fixed with support plates 3, and the lens is placed in the groove for cleaning and drying.

When cleaning a large number of lenses by leaving them in such a cleaning device, the lenses are first immersed in a bath of cleaning solution such as perchlorethylene or trichlorethylene to remove dirt and fog from the lenses. After that, the lens is cleaned by putting it in a water tank and a distilled water tank to remove the cleaning solution, then putting it in isopropyl alcohol, and finally drying it with Freon.

However, since the concave groove for holding the lens is formed by pressing a large number of plastic spheres, such as abacus beads, there is inevitably a slight gap between the abacus beads or a gap between the abacus beads and the support rod. This causes cleaning liquid, solvent, alcohol, etc. to enter into this gap, and some of this may remain, making the liquid leakage worse. Therefore, this residual liquid leaks onto the wall surface of the lens during the cleaning or drying process, creating spots with patterns and the like, which significantly impairs the commercial value of the lens.

The present invention has been made as a result of extensive research aimed at improving these drawbacks, and has resulted in the discovery of a cleaning support device that is excellent in draining water. That is, in the present invention, a plurality of fluororesin support rods each having a serrated V-shaped, U-shaped, or inverted trapezoidal concave groove along the longitudinal direction of the outer periphery are arranged side by side to form a V-shaped or U-shaped support rod. This method is characterized in that a mold shape is formed, both ends of which are fixed with support plates, and the object to be cleaned is placed in the groove and cleaned.

In the present invention, a plurality of support rods may be combined so that a lens or the like can be secured thereto, but it is particularly preferable to combine three or five support rods.

An example of the present invention will be explained based on the drawings.

As shown in Fig. 2, the outer periphery of the 3.5φ stainless steel core metal 4 has an outer diameter of 10.5φ and is pitched at an angle (θ) of 90°.
As shown in Fig. 3, three supporting rods 6 each having a fluororesin coating layer 5 having a 10 mm serrated groove are prepared and installed in parallel with each other in a V-shape, and each end is covered with a fluororesin coating layer 5. The cleaning device of the present invention was obtained by fixing the support plate 7.

The angle and pitch of the groove are adjusted according to the diameter of the lens, and the angle is between 20° and 120°.
Use a pitch in the range of 4 to 20 mm.

In the thus obtained device of the present invention, the concave groove on the outer periphery is molded integrally with the coating layer and no gap is formed, so that when cleaning the lens 8 by leaving it still as shown in the drawing, the cleaning liquid does not enter the core metal 4. It does not seep in and has excellent liquid drainage.

Furthermore, since the support rod and the support plate are made of fluororesin, they have excellent heat resistance and chemical resistance.

The device of the present invention is not only applicable to lenses, but is also useful for cleaning glass substrates, silicon wafers, etc.

Further, in the above embodiment, a case has been described in which three support rods are installed in a V-shape, but the present invention is not limited to this, and for example, four support rods may be used to form a U-shape. Furthermore, the number of support rods may also be five or more.

As detailed above, according to the present invention, when cleaning lenses, etc., the liquid drains easily, so there is no pattern or other spots on the cleaned lenses after cleaning or drying, significantly increasing productivity and commercial value. It has remarkable effects such as improving
