Description

one

The invention relates to automation and computing technology, in particular, to ycT-j tools for software etching by drilling machines, for example for drilling printed circuit boards.

Devices for software control of drilling machines are known, comprising: a control unit and a serially connected read unit, a decoder, storing registers, transforming;

codes and control units dvuhkoorcinatnygl stepper drive.

The purpose of the invention is to increase the speed. This is achieved by introducing a cycle counter into the device, the output of which is connected to the inputs of the code converters and the control unit, the output of which is connected to the inputs of the storage registers, code converters, reading block and loop counter, and the inputs to the outputs of the code converters and to the input cycle counter associated with the output of the decoder and to the course of the device.

The drawing shows a block diagram of the proposed device.

The device for software control of the machine contains a readout block 1, a decoder 2, an IR count 3 memory registers 4 and 5, a control block 6, converters 7 and 8 codes, a two-axis stepper drive control circuit 9, 10, an output 11 of the device from which it comes , to the machine (not shown in the drawing), the drill hole enable signal, and the input 12 of the device to which the drilling cycle termination signal is received from the machine tool.

The device operates from the program in which the movement of the working fgan of the machine from point to point is encoded. The drilling cycle is not programmed, but is automatically automatically positioned at the end. The processing of each hole has its own frame in the program, which contains the prizaki of the coordinates, according to which it is necessary to move the working body of the machine, the amount of this movement and the sign of the end of the calher. Processing a group of holes, placed on the same straight line and on an equal footing; Distances from each other are programmed with an IB single block containing the sign of the machining cycle, the number of holes in the group, the sign of the coordinates along which the working body must be moved, the magnitude of these displacements and the sign of the end of the block. In the process of reading frames from the software program (not shown) by block 1, the codes are decrypted in decoder 2, a sign of the processing cycle and a prize. coordinates (the control block 6 arrives; the value of the displacement along the coordinates is written into the storage registers. 4, 5, and the number of holes in the group is the count-1 tick of 3 cycles. At the sign of the end of the frame, a signal comes to the control, allowing a rewrite of the storage registers 4 and 5 L of the code converters 7 and 8. At the same time, a signal is sent to the converters J7 and 8. It transforms the recorded number and outputs the control signals to the circuits. The signal on the end of the conversion of both transducers 7 and 8 of the control unit 6 will give a signal from the output 11 of the drilling resolution device, and a single signal goes to the counter 3. After the drilling cycle of one hole is completed, input 12 The device receives a signal to the unit 6 of the control, according to which the census of the value is permitted, the nepeMeJ is canceled by the memory registers 4 and .5 f into the code converters 7 and 8. The processing cycle repeats until the number of honestly single signals coming from the control unit G to the counter of 3 cycles,:,; is equal to the number written to this counter from the program carrier. By this equality signal, the contents of the storage registers J, 4 and 5 and the control unit 6 outputs a signal to the van reading unit 1, allowing the reading of the next / program frame .; Single holes are made in the same way, only in this case), in the program frame there is no indication of the processing cycle of the group of holes, and the control unit 6 after processing the holes collects the contents of the memory registers 4 and 5 K and sends a signal to the read unit 1, allowing the next frame to be read . Formula 3 and J6 rea and Device for software control of the machine, containing a control unit and serially connected readout unit, decoder, memory registers, code converters, and control circuits, two-coordinate stepper drive, characterized in that, in order to increase the speed of the device, i enter the cycle counter / output of which is connected to the inputs of the code converters and the control unit, the output of which is connected to the inputs of the storage registers, code converters, block reads vania and loop counter, and inputs — to the outputs of the code converters and to the input of the loop counter, associated with the output of the decoder, and to the input of the device .;
