Description

The invention can be applied in microelectronics for microwire processing.

The aim of the invention is to improve the quality and intensity of cleaning microwires in a clean liquid medium by adjusting the pressure at the outlet of the instrument tube and separating the contaminants of the liquid medium, followed by filtration.

The drawing shows a device during its operation for cleaning microwires.

The device comprises a bath 1 with a liquid medium 2, in which a blade screw 3 is placed. The bath is equipped with a discharge and filtration compartment 4 with a filter 5 for discharging and filtering (cleaning) the contaminated liquid medium 6. A waveguide 7 of the ultrasonic transducer 8 is lowered into the liquid medium 2. A tool 9 is attached to the waveguide 7. It is made in the form of a cylindrical conical tube 10 with radial holes 11, the inner cavity of which is designed to process the microwire 12 supplied by means of rollers 13. Coaxially of the cylindrical conical tube 10 (from the side of its c of cylindrical portion) is set sucked fluid nozzle 14 of the jet pump (apparatus) 15 and is fixed to the tool 9 by means of the elastic member 16 (elastic tube or ring: bellows, etc.); The receiving chamber 17 of the jet pump (apparatus) 15 includes nozzles 18 with a working agent (gas, liquid, etc.) 19 supplied through the tube 20. The receiving chamber 17 passes into the mixing chamber 21, which ends with a conical diffuser 22, which is attached to the wall of the compartment discharge and filtration (cleaning) 4 using an elastic ring 23.

The microwire 12 is fed by means of a roller 13 into the cavity of the cylinder-conical tube 10 and through the nozzle of the suction liquid medium 14 into the chambers 17. 21 of the jet pump (apparatus) 15. located in the bath 1 with the liquid medium 2. Moreover, the nozzle of the suction liquid medium 14 is installed coaxially with the cylindrical-conical tube 10 and attached to the tool 9 with

using the elastic element 16, and the conical diffuser 22 of the jet pump 15 enters the discharge and filtration (cleaning) compartment 4 and is attached to its wall with the help of the elastic ring 23.

The elastic element 16 and the ring 23 help to reduce the loss of ultrasonic energy and the suppression of vibration.

Ultrasonic transducer 8 creates ultrasonic vibrations transmitted through the waveguide 7 and the walls of the instrument 9 to the tube 10. As a result, the microwire 12 is involved in the oscillation process, which allows the cavitation processes to be concentrated in the tube 10 and at the same time to calibrate the microwire 12 by smoothing the protrusions on its surface and the radial holes 11 in the tube 10 increase the access of the liquid medium to the cleaning zone with the screw 3.

At the same time, the working agent injected under pressure P (gas, liquid, etc.) 19 is supplied through the tube 20 to the receiving chamber 17 of the jet pump 15 through nozzles 18, the working parts of which are located symmetrically to each other relative to the longitudinal central axis of the internal cavity of the jet pump 15 (or at an angle of 120 ° relative to this axis), and also equidistant from this axis.

The outflow at high speed through the nozzles 18, the working agent 19 entrains the air in the receiving chamber 17. Due to the formation of vacuum, the liquid medium 2 with cavitation bubbles flows into the receiving chamber and the entrained working agent 19 flows into the mixing chamber 21 and then into conical diffuser 22. In the chambers of the jet pump 15 there is an intensive mixing of the flows of the working agent 19 and the absorbed liquid medium b with cavitation bubbles, which leads to an additional effect on the microwire 12 pos f its passage through the tube 10 of the tool 9.

Depending on the physicomechanical properties of the microwire 12, the pressure and flow rate of the working agent 19 are regulated. This makes it possible to control the pressure and flow rate of the liquid medium 2 and to provide maximum intensity of movement and action of the liquid medium 2 ’4 cavitation bubbles on both the microwire 12 and the tube 10 (at the narrowing of the conical section and at the finishing section), which contributes to the destruction of large particles of dirt in the narrow part of the tube 5.

The working agent 19 and the liquid medium 2 capture the products of contaminants and remove

them into the discharge and filtration (cleaning) compartment 4. where the contaminated liquid medium 6 is filtered (purified) by means of filters 5 and the purified liquid medium again enters

bath 1.

The use of a device for ultrasonic processing of microwire, equipped with a jet pump (apparatus) and a discharge and filtering compartment of contaminated

liquid medium, by adjusting the pressure and flow rate of the working agent, it is possible to control the pressure and flow rate of the liquid medium in the treatment zone, which allows to increase the kinetic energy of the liquid medium and cavitation bubbles, providing them with maximum intensity of movement and impact on both the microwire and tube (at the narrowing of the conical section and at the finishing section). it

0 contributes to the destruction of large particles of dirt in a narrow part of the tube and improves the quality of processing.

An additional effect on the microwire and in the chambers of the jet pump (unit 5), where the flows of the working agent and the liquid medium are mixed at high speed, which increases the intensity of the processing process.

In addition, due to the pressure created at the outlet of the tool, it is possible to remove contaminants from the treatment zone with their subsequent filtration (cleaning) in the discharge compartment, which allows the processing to be carried out only

5 in a clean liquid medium.

The claimed invention can be used for processing wire, filaments, etc., as well as in other industries.
