Description

DEVICE FOR ENGRAVING THE DECORATED ON THE PICTURES OF THE IMAGE

The utility model relates to the field of automation and computer technology and is intended to provide an automated engraving process on flat solid materials.

A device for engraving is known (see the Manual for the model 6A461 copy-milling machine, issue 1972, Lviv factory of milling machines), containing a cutting tool connected to a pantograph, which ensures its movement in two mutually perpendicular directions: X, U. The pantograph is controlled by an electric tracer. a drive that provides mechanization of the tracer's outline according to the model.

The disadvantage of this device is the manual process of controlling the movement of the pantograph under the action of the tracer during the stroke of the model. This eliminates the implementation of an automated engraving process.

The closest to the claimed utility model in terms of features is an installation for engraving an image decomposed into elements (see French application N2666278, MKI: V44VZ / 02, publication 03.06.92), selected for the prototype and containing an actuator, including an engine, transmission and dynamometer connect; the other is suitable. A tool (cutter) is installed at the output of the transmission, which has the ability to reciprocate and is located perpendicular to the material for engraving the image element. The installation also contains a control device, the first and second outputs of which are connected, respectively, with a dynamometric connecting device and a two-coordinate movement mechanism on which the material for engraving is located. The dynamometer connector turns off when the force transmitted from the transmission engine exceeds a threshold value. In this case, the engine acts on

IPC: V44VZ / 02

transmission with a force exceeding the maximum force required for the tool to grooves with maximum depth. The threshold signal generated by the control device, corresponding to the tone level of the engraved image element, enters the dynamometer connecting device for adjusting the threshold value necessary for engraving this element.

One of the disadvantages of the known installation is the impossibility of organizing an automated engraving process on flat solid materials.

This drawback is due to the lack in the control device of the ability to read digital image data and edit them.

Another disadvantage is the location of the material for engraving on the two-coordinate movement mechanism, which, with a significant mass of material, requires a significant effort when moving the two-coordinate movement mechanism.

The problem solved by the proposed technical solution is the creation of an engraving device decomposed into image elements with the provision of an automated engraving process on flat solid materials.

The technical result, which consists in providing an automated engraving process on flat solid materials, is achieved by the fact that the device for engraving an image decomposed into elements contains an actuator, at the output of which there is a tool with the possibility of reciprocating movement, and a control device, the first and the second outputs of which are connected, respectively, with the input of the actuator and the two-coordinate movement mechanism located Along with the material on which the engraving is carried out, an electric-output machine with software is inserted, the output of which is connected to the input of the control device, the two-coordinate movement mechanism is equipped with a movable carriage rigidly connected to the actuating device, and the control device contains a data receiving and processing unit, a generator with external start and stepper motor control circuit, while the first and second outputs of the data receiving and processing unit are connected, respectively, to the input g the generator with external start and input of the stepper motor control circuit, the output of the external start generator and the output of the stepper motor control circuit are, respectively, the first and second outputs of the control device, the input of which is the input of the data reception and processing unit.

Distinctive features of the prototype are the following features: the device for engraving the image decomposed into elements is equipped with an electronic computer (PC) with software, the output of which is connected to the input of the control device, the two-coordinate movement mechanism is equipped with a movable carriage rigidly connected to the actuator, and the device the control unit comprises a data receiving and processing unit, an external trigger generator and a stepper motor control circuit, wherein the first and the outputs of the data receiving and processing unit are connected, respectively, to the generator input with an external start and the input of the stepper motor control circuit, the generator output with an external start and the output of the stepper motor control circuit are, respectively, the first and second outputs of the control device, the input of which is the input of the unit receiving and processing data.

The specified set of features makes it possible to provide an automated engraving process on flat solid materials due to the conversion of the digital data array by computer software, which generates control commands for the control device according to a certain algorithm.

The device for engraving (see Fig. 1) contains an executing device 1, the output of which is installed a tool 2 with the possibility of reciprocating movement, a control device 3, the first and second outputs of which are connected, respectively, with the input of the actuator 1 and mechanism 4 two-coordinate movement, parallel to the material 5, on which the engraving is carried out, a computer 6 with software. The input and output of the computer 6 are connected, respectively, to the output of the scanner 7 and the input of the control device 3. The two-coordinate movement mechanism 4 includes a movable carriage 8, rigidly connected to the actuator 1.

The control device 3 (see Fig. 2) consists of a block 9 for receiving and processing data, a generator 10 with an external start, and an engraving circuit 11 s of stepper motors. The first and second outputs of the data receiving and processing unit 9 are connected, respectively, to the input of the generator 10 with an external trigger and the input of the stepper motor control circuit AND. The output of the generator 10 and the output of the stepper motor control circuit 11 are, respectively, the first and second outputs of the control device 3, the input of which is the input of the data reception and processing unit 9.

The main property of the actuator 1 is the provision of reciprocating movements of the tool 2 with a constant frequency. This property (function) can be organized on the basis of an electromagnet with a return spring, as well as an electric motor with a cam mechanism, etc.

One embodiment of actuator 1 is shown in FIG. 3. The actuator 1 consists of an electromagnet 12 connected by an arm 13c with a movable carriage 8. An electric motor 15 is mounted on the movable armature 14 of the electromagnet 12, on the shaft of which is fixed a tool 2 (milling cutter, drill, etc.).

captive electrode for electrospark engraving method. Moreover, metals are used as material 5 for engraving.

Computer 6 can be implemented on a personal computer such as IBM PC with an 80386-SX processor, an 80387 coprocessor, and a minimum of 4 MB of RAM.

Scanner 7 can be implemented on a Logitesh ScaiiMan-256 scanner.

Block 9 data input and processing can be implemented according to the scheme of the control device YaGMZ.917.902 EZ l1, l2 (documentation for the output device for graphic information Electronics Electronics MS 6501, folder N2).

The generator 10 with external start can be implemented according to the scheme given in the reference book of V. L. Shilo. Popular digital circuits. Chelyabinsk Metallurgy Chelyabinsk Branch, 1989, p. 214.

The control circuit 11 of the stepper motors can be implemented according to the scheme of the control device YaGMZ.917.902 EZ lZ (documentation for the input device for graphic information Electronics MS 6501, folder N2).

The two-coordinate movement mechanism 4 (see Fig. 5) consists of a fixed guide 18, on which the stepper motor 19 is fixed. The rotation of the stepper motor 19 through the belt drive 20 is converted into reciprocating movements of the movable beam 21 along the X axis. The motion of the movable beam 21 along the fixed the guide 18 is carried out by means of three support rollers 22. A stepper motor 23 is mounted on the movable beam 21, which provides reciprocating movements of the movable carriage 8 by means of a belt drive 24. Under izhnaya carriage 8 is moved by a movable beam 21 on three supporting rollers 25 along the direction of axis Y.

Stepper motors 19,23 can be implemented on an engine of the DSh-200-05 YAGMZ.595.292 type.

Device for engraving works as follows. The original image (drawing, photo, etc.) is converted by the scanner 7 from the optical range into a digital data array, which is recorded in computer 6. With the image recorded in computer 6 (in the form of an array of data), the necessary editing is performed using standard software tools.

A digital array (image) can be obtained without using a scanner 7, but by drawing a picture using standard software.

The image data array obtained after editing is processed using a special program. The specified special program implements the developed principle of obtaining a grayscale image. Computer 6 provides forwarding in the required data format for operation of the control device 3. For the two-coordinate movement mechanism 4, the control device 3 generates two types of control commands (for stepper motors 19, 23); the first type is for organizing horizontal deployment of an image along two coordinate axes X, Y, and the second type is for controlling the speed of movement along a line. For the actuator 1, the control device 3 generates control commands in the form of packs of periodic (with a constant frequency) commands (electrical pulses). Under the action of control commands (applying voltage to the winding of the electromagnet 12), the movable armature 14 is set to the operating position. The return of the movable armature 14 after the loss of control commands to their original position is carried out under the action of the return spring 16. Moreover, when the control commands are supplied to the actuator 1, this corresponds to the process of influencing the material 5 for engraving, and the absence of commands to the idle passage of the actuator 1 by line. Thus, in the engraving process, line-by-line movement of the actuator 1 is carried out by means of the two-coordinate movement mechanism 4. Moreover, under the action of control commands, the actuator 1 performs periodic, with a constant frequency, vertical movements. Each lowering of the actuator 1 and, accordingly, the lowering of the tool 2 fixed in it, ensures the application of a single image element — an oval point — on the surface of the material 5. The direct process of point formation is provided by tool 2. After starting the engraving process, the operation of the claimed device is carried out in automatic mode.

With this embodiment of the engraving device, the provision of an automated engraving process on flat materials is achieved by converting the received digital data array in accordance with a computer program that generates control commands for the control device according to a certain algorithm.
