Definitions

  • the present invention relates to the centering of the blanks of optical glasses prior to the operation of grinding them to the dimension of the circles of a given frame, on a grinding machine, as well as the control of a precalibrated glass.
  • an optical glass blank is held between two ends of a divided shaft of a grinding machine by means of an adapter, which is usually a suction cup applied with precision on the axis of rotation of the blank. .
  • This centering of the adapter is a complex operation which must be carried out taking into account various factors which are different for each user.
  • the precision of this operation conditions the correct execution of the rectification of the blank and the best adaptation of the lenses to the user of the finished spectacles.
  • Patent EP-A-0 092 364 describes in particular a method and an apparatus for its implementation, as well as patent FR-A-2 547 930 which more particularly relates to a grinder with numerical control.
  • the object of the invention is to simplify these various operations by providing an improved device for centering and fitting the adapter on a blank of optical glass in a more precise manner, this device itself establishing the information necessary for ordering. direct from the grinding machine according to the user's specific morphological data and that of the chosen frame.
  • the object of the invention is for this purpose an apparatus for centering and placing an adapter on a blank of optical glass and for automatically establishing the information necessary for the rectification of the blank on a grinding machine, and suitable for directly controlling the latter, this device being of the type comprising a stored data bank, a computer with a display screen and a mechanical device for fitting an adapter, characterized in that it comprises a flat electronic display screen, a control device for moving on said screen an image stored in said bank of a mount, or of a given template, an electronic device for recording the displacements of said image on the screen, memorizing the differences in its final coordinates relative to a position reference formed by the intersection of two orthogonal axes X, Y and calculate the resulting information and apply it directly to a grinding machine, and a disposi swivel lens for optical aiming and fitting an adapter.
  • said flat screen is of the liquid crystal type.
  • a sheet of transparent material arranged on said screen and having in its middle two graduated orthogonal axes.
  • said means for displaying and moving an image of a frame or a template given on the screen are constituted by a programmable electronic computer.
  • said means for recording the displacements of the image on the screen and memorizing the differences in these final coordinates with respect to the data entry or storage position are constituted by said computer.
  • a caliber 1 is usually drilled in the center of a hole 2 and also includes two small holes 3 located at an equal distance from the center of the hole 2 and determining an axis of origin O which is parallel to a straight line joining the pupils of the user when the template is mounted on a pair of glasses worn by the user.
  • the template also includes a second axis H orthogonal to axis 0 and passing through the geometric center of the template.
  • An optical glass blank designated by the reference 4 in FIG. 2 carries, traced thereon, two orthogonal axes 0 'and H' crossed at the optical center of the blank and which are usually traced by means of an erasable ink.
  • the pupils P of a user wearing a frame M are spaced by a distance called pupillary distance EP while the geometric centers of the templates (or circles of the frames) are spaced by a distance EGM representing the geometrical difference of the frame which, in this example, is a little greater than the distance EP.
  • an adapter is placed on the center of rotation of the lens which corresponds to the geometric center of the template, in known manner.
  • the apparatus according to the invention allows this centering to be carried out with ease and precision.
  • This device shown in perspective in Figure 4 includes a support 5 having a keyboard 6, the assembly having for example a shape similar to that of a conventional typewriter.
  • the support 5 carries at its upper part a flat electronic screen 7 which is for example a display screen of the liquid crystal type.
  • an optical sighting device Opposite the keyboard relative to the screen 7 is mounted an optical sighting device which will be described in more detail below.
  • the support 5 contains an electronic assembly constituted by a computer 8 connected to the screen 7 in an appropriate manner, a data bank 9 or other suitable memory system, and a data entry device 10. This electronic assembly is linked to a grinder 11 with numerical control. On the screen 7 is disposed a sheet 12 for example of transparent plastic or glass carrying in its middle two orthogonal axes X, Y which are graduated.
  • the keyboard 6 includes a control device 14 which, according to the example shown, consists of keys.
  • the device mounted on the rear part of the support 5 comprises a fixed vertical upright 15 on which is slidably mounted an elongated body 16 urged upwards against a stop 17 by means of a spring 18.
  • the body 16 has at one end a first arm 19 extending horizontally and at its opposite end a second arm 20 also extending horizontally but offset by 90 ° C relative to arm 19 and of the same length.
  • the arm 19 carries at its end an optical device 24, the length of the arm being adapted so that this device 24 can be brought to the vertical of the intersection of the axes X, Y of the sheet 12.
  • the arm 20 carries at its end a support 21 adapted to receive an adapter 22 constituted for example by a suction cup in a removable manner.
  • the body 16 is rotatably mounted on the axis 15 and can be displaced in height by translation on this axis, by means of a control member 23.
  • the screen 7 is displayed on the screen 7 by means of the computer 8 of a chosen frame of which the data are stored in the bank 9.
  • the computer having in memory the data corresponding to the chosen frame progressively records the displacements of the shape from its position from the entry or storage position and calculates the differences with respect to the data of the frame and restores the shape of the frame centered according to the pupil position of the user.
  • the glass blank is then placed manually on the screen so that its optical center coincides with the intersection of the X, Y axes and is checked by means of the optical device 24 which makes it possible to observe the image without correction of parallax that the image of the mounting circle (or template) is indeed contained in the blank.
  • the body 16 of the device is then rotated by 90 ° to bring the adapter 22 into position above the blank and place it thereon.
  • the input device 10 contained in the electronic assembly of the device can be a device as described in FR-A-2 229 213 which comprises a probe adapted to follow the contours of a frame circle or a template and send signals which can be entered directly into the computer 8 in place of the data stored in the bank 9.
  • the device according to the invention makes it possible, from a frame shape or a chosen template and by entering into the calculator linked to the screen, the particular morphological data of a user, automatically establish the information necessary to order a grinding machine, and also determine the characteristics of the glass: maximum diameter and critical radii for the purchase of special glasses (precalibrated glasses).
  • the device according to the invention makes it possible to directly control the grinding machine as a function of the measurements carried out by moving the image of the frame or of the templates on the screen 7 of the device.
  • the device according to the invention allows centering to be carried out at the particular dimensions of the end user of the frame and that, if desired, a printer can be connected to the computer 8 in order to print all the dimensions d '' a given lens, intended for the manufacturer to make this lens for a given frame and a given client (pre-calibrated lenses).
  • the screen 7 used having a definition of a few tenths of a millimeter, we obtain with the apparatus according to the invention a completely satisfactory precision.
  • the computer can be adapted to display the orthogonal axes X, Y directly on the screen.
