Definitions

  • the invention relates to a holding device for parts, in particular small parts, such as optical lenses, electronic components or the like, hereinafter referred to simply as lenses, in a device for further treatment of the parts, for example in order to be able to clean them with the aid of ultrasound or to to provide them with a thin layer, for example to temper lenses or to cover other parts with a precious metal or the like.
  • the lenses for example particularly small lenses for an endoscope
  • the lenses are arranged on a base which is then inserted into the cleaning device together with the lenses.
  • the lenses are then cleaned on one side using ultrasound.
  • the lenses are turned over so that the back of the lenses can now be cleaned. Since the lenses have to be cleaned several times after various processing operations, this cleaning is cumbersome and time-consuming.
  • FIG. 5 page 341 "The Encyclopaedia of Workshop Practice" to arrange the parts to be treated in certain directions, which would mean for an ultrasonic cleaning device that the ultrasonic waves strike the surfaces of the parts to be cleaned at particularly favorable angles of incidence.
  • the parts can be pivoted so that their back is easy to clean. From the same reference, Fig. 24 on page 663, it is also known to incline the parts to be treated for processing.
  • This device is therefore not suitable for cleaning a large number of small components at the same time, in particular from two sides at favorable angles of incidence of ultrasonic waves, and they cannot be placed on a surface in an orderly manner after cleaning.
  • the features of the preamble of claim 1 are known from this document
  • the object of the invention is to provide a holding device for the parts to be cleaned, with the aid of which the parts can be arranged more easily than before, for example in an ultrasound cleaning device, and can be treated more effectively than before, in order then to be placed in an orderly manner on a base.
  • the characterizing feature of claim 1 Because the parts are now arranged in cages, so to speak, and the cages can be pivoted into any position, the receptacle can assume a position by, for example, the ultrasound hitting the lens surface at a particularly favorable angle. To clean the back of the lenses, the holder is then only pivoted through 180 °.
  • the plates for receiving the parts to be cleaned are arranged in resilient brackets, in which the plates can be tilted and / or turned over with the aid of a latching device.
  • the holding device has top and bottom perforated plates delimiting the receiving plate with openings which are larger than the parts to be cleaned, and which also expand conically outwards, so that, for example, the ultrasonic waves even when the holding device is inclined without hindrance up to Lenses can penetrate.
  • the entire device can be removed from the cleaning device with the aid of the bracket and arranged in such a way that the cleaned lenses can be tilted onto a base.
  • the cleaning device according to the invention is characterized in that the parts to be cleaned, such as optical lenses and also electrical components, are each arranged in a cage which is closed on all sides and which is permeable to the cleaning liquid and for further processing.
  • the holding device 1 consists of a plate 2 with openings 3 for receiving the parts to be cleaned, in the present case of optical lenses 4.
  • a screen 5 is firmly connected, which prevents the lenses 4 down through the openings 3 fall out.
  • a perforated plate 6 is arranged below the screen grid 5, the openings 7 of which are larger in diameter than the openings 3 of the receiving plate 2 and which expand conically towards the outside.
  • On the plate 2 is a another screen grid 15 is placed and on this grid 15 a further perforated plate 16 with openings 17 which are mirror images of the openings 7.
  • the plates are held together by two clamping pieces designed as U-shaped plates 20 by pushing them over the edges 30, 31 of the plates.
  • the plates 2 and 6 and the screen grid 5 are firmly connected to one another once and for all by screws 21.
  • the receiving plate 2 and the screen 5 and 15 are made of a plastic, preferably Hostaflon (trade), because this material is insensitive to ultrasound, that is, no atomic particles detach from them when irradiated with ultrasound, so that settling such particles on the lenses is prevented during the cleaning process.
  • the perforated plates 6 and 16 and the clamp holder 20 are made of stainless steel.
  • the holding clips 20 each carry a pin 22, on the body 23 of a resilient bracket 24 can be plugged.
  • the bodies 23 have recesses 26 in the manner of a spur toothing, into which the edges 30 and 31 of the plates or the retaining clips 20 snap.
  • the holding device 1 can thus, as shown in Fig. 4, be inclined to the bracket 24.
  • the inclination can be chosen so that the ultrasound hits the part to be cleaned at a favorable angle, so that an optimal cleaning effect is achieved. This saves operations, in particular repeated cleaning of the parts.
  • the openings 7 and 17 are widened outwards to be conical.
  • the bracket 24 is released from the holding device 1, the clamping means 20 are removed from the plate edges, and the perforated plate 16 and the screen 15 are removed.
  • the cleaned lenses can be tilted onto a base by first placing the base on the open side of the mounting plate 2 and plunging it together with the base. The lenses then lie with their correct side up, aligned on the base.
  • An individual removal of the lenses from the holding device according to the state of the art with the aid of tweezers while turning and placing the individual lenses on the support is not necessary according to the invention.
