Identification mark for marking valuables and method of making said mark / 2373307

Invention relates to apparatus and methods of marking valuables, mainly precious stones, particularly cut diamonds, and can be used for subsequent identification of data of the valuables. Mark 1 is made in form of an image, which is optically visualised in diffraction-reflection light, made on the polished surface 3 of the valuable object 2. The structure of the image is formed by a modified area of the surface layer of the object 2 with optical properties in the said area, which is functionally the image of mark 1, altered from the initial properties. The modified area is made in form of microlines 8, spatially formed according to type of the reflection grating, which is functionally an apparatus for increasing contrast of visual perception of the image of marker 1 in at least one of the colour hues of the spectrum of incident radiation. The structure of microlines of the modified area includes at least one impurity additive, which is selected from a group which includes noble metals or boron, ion-implanted into atomic lattices of the initial material of the object without breaking interatomic bonds of these lattices and, therefore, without changing quality of the polished surface of the object, but with change of the complex refractive index of this material. According to the method of making mark 1, before modification, a technological layer (TL) of material, which is removed after modification, is deposited on surface 3. A structure is formed in the technological layer according to type of the line grating. The corresponding area of the surface layer is modified by exposing this area to an ion beam through a mask with an image of mark 1 and the spatial structure formed in the technological layer, that way creating process conditions implantation of modifier ions into the modified area of the surface layer of the material of object 2 without breaking bonds in the atomic lattices of this material and, therefore, without changing initial quality of polishing the surface layer, but with change of its initial optical properties. The modifier used is impurity additives, selected from a group which includes noble metals or boron, ions of which alter the complex refractive index of the modified layer.

The disadvantage of this device is its ability to work only in manual mode and perform engraving only on the copied template that is larger than the workpiece.

Also known engraving machine for products with non-planar surface (U.S. patent No. 3830136, 1974). And in this case, the engraving is done manually with the image transfer flat pattern using a structurally complex system of pantograph.

Famous engraving unit (patent RF №2309648, 2007), containing a two-coordinate scanning device, means for mounting and moving the object to be processed, a laser tool for surface treatment and the control device, in the form of a personal computer, containing connected to the microcontroller monitor and keyboard. The unit is designed to handle is poverhnosti large objects, mainly stone slabs, is a sophisticated design and sophisticated electronic equipment.

The present invention represents an engraving machine to perform the engraving work on small items such as medallions.

Engraving machine according to the invention includes a housing, a base, vertical posts and the transverse wall, the horizontal and vertical Desk, shop for billets, feeder blanks, shop for packaging, magnetic drum head, feeders desktop, the restraint of the workpiece in the process of engraving cycle, the device issuing the finished product and packaging at the end of the working cycle, the sensor positioning and control, and electronic control unit. Horizontal Desk rests on the transverse wall and the vertical Desk relies on vertical racks.

The casing as the casing, to protect the actuators from the influences of the external environment. It has openings for the output signal and control wires, lights, installation shops. The Foundation is a supporting structure on which are mounted the other elements of the machine. In particular can be made of two aluminum squares. Vertical racks are attached to the basis of aniu and together with the base and lateral walls form the main frame of the machine.

Device for conveying workpieces are performed in a stationary pusher, pushing part of which is made in the form of complementary used the workpiece, for example, molded rectangular plates of the U - shaped pusher.

The restraint of the workpiece is designed to eliminate vibration and displacement of the workpiece during the working cycle. For metallic workpieces can be an electromagnet.

Desk is a plate with the mounting holes. Just the engraver two desktops, providing the movement of the workpiece (for example, medallion) on the X-axis and moving the tool (magnetic impact sockets) on the axis Y. in Addition, the table X-axis allows you to push the packaging for engraved products from shopping packaging, and table Y-axis provides automatic feed medallions, pushing their follower of shops for billets.

The feeders desktops provide the propulsion desktop. In a preferred embodiment, such mechanisms is made on the basis of the transmission screw and cylindrical guides. Can also be used for the ball screw, gear transmission, linear drives and guides of a different type (for example, rail guides).

Magnetic drum head is with the battle of the solenoid core, engraving needle and spring return. The movement of the needle is provided by applying voltage to the coil of the solenoid, the return - spring return. The force of impact is governed by the amount of current or the current feed to the coil of the solenoid.

The device issuing the finished product and packaging at the end of the working cycle is intended for issuing engraved products and packaging to him upon completion of the operating cycle. It can be implemented in the form of pushers, driven desktops, or as separate mechanisms.

Shops for packaging can be a few with shops on one side of the machine, and on both sides of the engraving machine.

The positioning sensors and controls designed to detect the position of the working parts of the machine, fullness shops preparations and packing material, verify the correct installation of these shops. Mostly they represent optical pair. Can also be used inductive or capacitive sensors.

The electronic control unit is a specialized controller, providing interfacing the computer with the actuators and sensors of the machine. The computer may be installed under the cover engraving machine, or run in the form of individual p the th block, connected to the controller and connecting cables.
