Description

description

The invention relates to a holding device for parts, in particular small parts, such as optical lenses, electroni-S see components or the like, hereinafter referred to as lenses for the sake of simplicity, in a device for further treatment of the parts, for example to be able to clean them with the help of ultrasound or to be able to clean them with a thin To provide a layer, for example to anneal lenses or other parts with a noble metal or the like occupy.

According to the prior art, the lenses, for example particularly small lenses for an endoscope, on a placed underlay, which then with the lenses in the cleaning device is introduced. The lenses are then cleaned on one side with the help of ultrasound. The lenses are then turned over so that the rear side of the lenses can now be cleaned. Because the lenses have to be cleaned several times after various processing operations, this cleaning is cumbersome and time-consuming.

The object of the invention is to provide a holding device for the parts to be cleaned, with the help of which the parts easier than before, for example, arranged in an ultrasonic cleaning device and treated more effectively can than before.

This object is achieved by the characterizing feature of claim 1. Because now the parts are firmly in the Recording are arranged and this can be pivoted into any position, the recording can assume a position For example, the ultrasound hits the lens surface at a particularly favorable angle. For cleaning the back of the lenses is then simply

In a special embodiment of the invention, the plates for receiving the parts to be cleaned are in a Fe-S arranged stirrup in which the plates are positioned at an angle with the aid of a latching device and / or turned around can.

The holding device has perforated plates delimiting the receiving plate at the top and bottom with openings which () are larger than the parts to be cleaned »and which also expand conically towards the outside, for example the ultrasonic waves penetrate as far as the lenses without hindrance even if the holding device is tilted can.

Further details of the invention can be found in the claims and in the description of the drawing.

In the drawing, an embodiment of the invention is shown, namely show:

1 shows the plan view of the holding device;

FIG. 2 shows a section along the line II-II of FIG. 1;

3 shows a section along the line IH-III in FIG.

4 shows the view of the holding device in the direction

of arrow IV of FIG. 1.

j 30 The holding device 1 consists of a plate 2 with; openings 3 for receiving the parts to be cleaned, in the present case Case of optical lenses 4. With the plate 2, a sieve grid 5 is firmly connected, which prevents the Lenses 4 drop down through the openings 3 below of the sieve grid 5, a perforated plate 6 is arranged, the

Openings 7 are larger in diameter than the openings 3 of the receiving plate 2 and which are conical towards the outside expand. A further sieve grid 15 is placed on the plate 2 and a further perforated plate 16 is placed on this grid 15 S with openings 17 which are a mirror image of the openings 7. The plates are held by two U-shaped sheets 20 formed clamping pieces held together by sliding them over the edges 30, 31 of the plates, The Plates 2 and 6 and the sieve grid S are firmly connected to one another once and for all by screws 21.

The mounting plate 2 and the sieve grids S and 15 are made made of a plastic, preferably made of Hostafion (Handelsnattw), because this material is insensitive to ultrasound is, that is, no atomic particles are released from them when irradiated with ultrasound, so that [A settling of such particles on the lenses during the

Cleaning process is prevented. The perforated plates 6 and 16 and the clamp holders 20 are made for the same reason made of a stainless steel.

The retaining clips 20 each carry a pin 22, onto which the body 23 of a resilient bracket 24 can be plugged. the

Body 23 have recesses in the manner of a spur toothing j 25 26, in which the edges 30 and 31 of the plates or the Halteklanunern 20 snap.

j The holding device 1 can thus, as shown in Fig. 4,

be employed at an angle to the bracket 24. The inclination

S can be chosen so that the ultrasound under a green ^

j 30 stigen angle meets the part to be cleaned, so that a optimal cleaning effect is achieved. This eliminates the need for operations, in particular repeated cleaning of the parts, saved.

So that the ultrasound unhindered on the lenses 4, too

at an inclined position of the holding device 1, meet can, the openings 7 and 17 are outwardly too conical expanded.

After cleaning, the bracket 24 is released from the holding device 1, the clamping means 20 are removed from the plate edges withdrawn, and the perforated plate 16 and the sieve grid 15 will be removed. The cleaned lenses can now be tilted onto a base by moving the base first lays on the open side of the mounting plate 2 and this falls together with the pad. The lenses are lying then right side up, aligned on the surface. A single removal of the lenses from the Holding device according to the prior art with the help of tweezers while turning and placing the individual lenses on the document is omitted according to the invention.
