Definitions

  • the subject of the invention is a method of coating the surface of an object with a film of stretched paint, generally glossy, as well as a device intended for carrying out this method.
  • the object of the invention is to improve the visual appearance of a finish coating or paint applied to a support of ferrous or non-ferrous metal, plastic or composite materials.
  • metal or plastic support it is necessary to understand the nature of the main part which receives all of the finishing layers, whether it is pre-coated with one or more thin layers of natures other than the support for metal parts, whether plastic or fiberglass composite material injected or pressed.
  • the method according to the invention makes it possible to improve the appearance of the paint film obtained after curing, while remedying the aforementioned drawbacks.
  • a mechanical action is exerted on the paint film, between the application of the product to the object to be painted and the start of crosslinking by subjecting it to ultrasonic radiation.
  • the acoustic density of the ultrasonic radiation is distributed in a substantially uniform manner over the entire surface whose appearance is to be improved.
  • the low frequencies of the ultrasonic spectrum are used.
  • the coating comprises several layers, the final layer possibly being a varnish.
  • a device for implementing a method according to the invention is characterized in that it comprises a plurality of ultrasonic transducers arranged substantially equidistant from the surface to be treated and emitting in the direction of this surface.
  • such a device will include handling means supporting the object to be treated and ensuring a regular movement of movement of this object relative to the transducers.
  • transducers it is advantageous for the transducers to be arranged on supports, each partially enveloping the object to be painted in sections perpendicular to the direction of the scrolling movement.
  • the supports include means allowing their translation in a direction perpendicular to the direction of travel and to the surface of the object to be treated opposite which they are located, so as to maintain substantially constant the distance between the transducers they carry and the corresponding surface of the object to be treated.
  • the supports can be produced in the form of parallelepiped boxes each arranged parallel to the mean plane of one face of the object to be treated.
  • the objects to be painted are boxes of motor vehicles.
  • the device 2 for implementing the method according to the invention is inserted in a conventional industrial painting installation between a cabin 1 for applying a final layer, for example a varnish, and a baking tunnel 3, where the crosslinking of the applied product takes place.
  • the treated bodies 4 are fixed (FIG. 3) to handling carriages 5 which move continuously, in the direction of the arrows F, from the cabin 1 to the tunnel 3 through the device 2 in a regular movement.
  • the device 2 essentially consists (FIG. 4) of a plurality of transducers or ultrasonic transmitters T1, T2, T3 ... continuously emitting a beam of ultrasonic waves towards the surface of the body.
  • the antennas or transmission members of these transducers are arranged in such a way that the acoustic density exerts on the paint film a mechanical effect uniformly distributed over the entire surface, the appearance of which is to be improved.
  • the transducers are distributed over the surfaces of frames or boxes 6 to 10 enveloping the lateral and upper parts of the body 4.
  • Each frame 6 to 10 further comprises means 61 to 101 making it possible to maintain a constant distance between the antennas of the transducers and the surface to be treated.
  • These means for example jacks, ensure a translation of the frames in both directions in a direction substantially perpendicular to the body part arranged opposite (arrows f).
  • two frames 6,7 and 8,9 are arranged vertically symmetrically opposite the side panels of the bodywork which precisely constitute the most demanding areas from the point of view of visual appearance.
  • At least one frame 10 is arranged horizontally, facing the horizontal upper parts (hood and roof), it has a greater amplitude of translation to overcome the jump formed by the windshield bay.
  • the carriage 5 having progressed in the direction of the arrow F, the frame 10 s is moved vertically upwards according to f
  • the frames 6 to 10 somehow envelop the object to be painted in sections perpendicular to the direction of the scrolling movement according to the arrow F.
  • the emitting faces of the frames 6 to 10 are shown planar, they could of course be of concave shape to better envelop the object to be treated.
  • the transducers 6 to 10 can be magnetostrictive or piezoelectric types and are used in the lower frequency spectrum of ultrasound.
