Description

  one

The invention relates to electrochemical processing, in particular, devices 4 for electrochemical arcing of products from conducting materials.

The purpose of the invention is to increase the speed when marking signs, performed in a certain sequence, by automatically changing the sequence number, as well as by working in automatic mode, as the marked number is dialed once, and the subsequent numbers are changed automatically. marked product.

Figure 1 presents the scheme of the device; figure 2 is a functional diagram of the pulse generator.

The device contains a program set block 1, a pulse shaper 2, a memory block 3, code converters, a current source 5, a group of 6 key elements, a block of 7 marking elements 8, a marked product 9, display units 10, a touch sensor 11. Memory unit 3 contains pulse counters by the number N of channels.

Form number 1 pulse 2 contains the first elements AND-NOT 13 and the second element AND-NOT 14,

Unit 1 of the programming kit can be executed on the priority Encoder chips (for example, K155IV1) and 4-2I-NOT chips (for example, K155LAZ), and the driver 2 pulses can be performed on logic elements 4-2I-NOT (for example, K155LAZ).

Memory block 3 can be executed on counters with a preset (for example, K155IE6), and the code converter can be executed on the decoder K514NTs2.

Key elements can be performed on the LOT 11OB optocouplers and the KT814B transistor, and the display elements on the seven-segment indicators of the ALS324B type.

The device works as follows.

Marked product 9 is connected to the positive pole of the current source 5, and marking elements 8 are connected to the negative pole of 968142.

5 current point through a group of 6 key elements.

If none of the buttons is pressed, the control voltage to the output is

5 of block 1 of the program set has a logical zero level. If you press any button, then at the output of the program task block, the code corresponds to the number of the pressed button, and at the control output, the logic unit level, which is converted by the shaper 2 pulses into a pulse, whose duration is equal to the delay time of three elements 13.

When you press the button of the desired sign from the outputs of block 1 of the program, the signal in encoded form is fed to the installation inputs

20 counters 12 junior bits of memory 3. Simultaneously, from the output of block 1 of the program set, the signal is fed to the input of the imager of 2 pulses, from the output of which goes to the inputs C of the counters of the 3 Memory block. Since the code of the pressed button is set on the installation counters of the lower bit of the memory block 3, the trailing edge of the pulse

30 incoming from the imager 2 pulses to the inputs C of the counters, in the counter 12 | the low-order bit will write the code of the specified button.

When you press the button, the trace of a marked mark from the outputs of block 1 of the program set, the signal in encoded form is again fed to the installation inputs of the counter 12. low-order RAM

3i, the pulse shaper 2 is started, from the output of which a pulse arrives at the inputs C of all counters. The 12 least significant bit will be written to the counter - the code of the second marked

45 characters, and in the second digit counter 12 - the code of the first mark to be marked, i.e. there will be a shift of the previously recorded code to the next bit of memory block 3, and so on until the last marked character is dialed, the code of which will be recorded in the 2ff high-order counter. From the outputs of the counters, the codes go to the inputs of code converters 4 one by one

55 in each category de. The binary code of the sign i at the input of the code converters

4 is converted at the output to a code of markable characters (for example, a seven-segment code). Each output of the code converter 4 is connected to a key element 6, from the outputs of the code converter 4 signals arrive at the opening of a group of 6 key elements corresponding to the marking elements 8, and simultaneously the signal from the other outputs of the key elements 6 goes to the display units 10.

During the pressing of the block 7 of the marking elements 8 to the marked product moistened with electrolyte, the process of electrochemical marking of specified signs occurs, and the sensor 11 of the touch of the marked product 9 forms a zero level at the output. When the block 7 of marking elements 8 is retracted from the marked product 9, a high voltage level is formed at the output of the sensor 11 touching the marked product 9, which is fed to the counting input of the low-level counter 12 of the working memory 3, the counter code changes by one, and during pressing the next product 9, the process of electrochemical marking of the next number takes place without prior dialing,

Thus, the proposed device provides an automatic change of numbers when marking characters that change in a certain sequence.

 In the device, the marked number is dialed once, and the subsequent numbers are automatically replaced by a signal from the sensor of the presence of the marked product. If in a known device the time for labeling a single product

Since the time of the flow of electrochemical processes is commensurate with the time of a set of one sign, then in the case when t, t, the speed of the proposed device will increase Q times, where

In the proposed device, in addition to the increased speed when typing characters, which is known device, and the ability to count products, which are taken separately counters products, speed increases (n + 1) times, where n is the number of characters in the number, when marking signs , changing in a certain sequence as well as in connection with the automatic change of marks, it is possible to use the device in automatic lines and work technology complexes.
