Abstract
Disclosed is an electrochemical marking machine capable of randomly generating preset mark texts and patterns on the surface of a to-be-marked workpiece. An electrolyte is jetted from a nozzle to the surface of the to-be-marked workpiece through a pump; current for electrolytic corrosion and oxidation or electrolytic reduction and deposition is conducted through electrolyte jet flow. The electrolyte nozzle is driven by a numerical control cross slippery platform to perform two-dimensional scanning over the to-be-marked workpiece, connection and disconnection of electrolytic power output are controlled synchronously, so that metal is electrolytically corroded and oxidated from the two-dimensional area of the surface of the to-be-marked workpiece or the metal is electrolytically reduced and deposited to the two-dimensional area. Compared with an existing electrochemical marking machine, the electrochemical marking machine is unlimited to templates and capable of randomly generating the preset mark texts and patterns.
Description
Technical field
The present invention relates to a kind of device made marks on metal, produce the device of mark meter especially by electrochemical method.
Background technology
At present, known electrochemistry marking machine is made up of power supply, labelling head, wire.Labelling head have one piece conduct electricity and can absorb the carbon felt electrode of mark liquid, be surrounded by the nonconducting screen template of one deck outside electrode, template part mesh is penetrating, and penetrating mesh forms pattern and word.During mark, by treating that the workpiece of mark is connected to the positive pole of power supply, labelling head being connected to the negative pole of power supply, dipping with labelling head and being a certain amount ofly dissolved with electrolytical mark liquid, then labelling head being contacted workpiece.Power supply by drive current by workpiece via electrolyte, by mesh penetrating in template, flow on carbon felt electrode.At surface of the work, due to electrochemical effect, metal becomes ion and enters electrolyte.After about tens seconds, the galvano-cautery mark consistent with pattern in template can be produced at surface of the work.Use different electrolyte, the mark of different colours can be left on metal.This mode shortcoming by template mark is, cannot determine beaten pattern and word content at random when mark.People usually need to stamp on workpiece the content that sequence number and date-time etc. need to change at any time.The electrochemistry mark of template is used to be difficult to meet the need.
Summary of the invention
In order to overcome the deficiency of existing template electrochemical marking machine, the invention provides a kind of electrochemistry marking machine, what this marking machine can be random gets required various pattern and word.
The technical solution adopted for the present invention to solve the technical problems is: labelling head is by undissolved metal manufactures under anode polarization current potential such as stainless steel, titanium (can apply iridium dioxide on surface to reduce overpotential) or lead, the pipeline that its inside has electrolysis liquid to flow through, there is an aperture front end.During mark, will treat that the workpiece of mark is connected to the positive pole of power supply, by the negative pole of the Electrode connection of labelling head inside to power supply.Electrolyte is driven to go out one electrolyte jet via the small hole injection on labelling head by pump.This jet is ejected into be treated on the workpiece of mark.Labelling head is driven to treat that mark overlying regions does scanning motion by computer-controlled stepper motor by screw mandrel.Simultaneous computer Synchronization Control from workpiece via the break-make of electrolyte jet to the electric current of the circuit of labelling head.Electric current by time, the some metal that jet is ejected into by electrolysis thus ionization dissolve, when circuit disconnects and do not have an electric current, the some metal that jet is ejected into can not be dissolved.Like this after jet completes scanning motion, corresponding point just leaves workpiece the vestige of needs, these vestiges just can form the pattern and character of needs.
When scanning, the speed that just can also be scanned to a point by Control Nozzle or control carry out the depth of control mark by the size of the electric current between nozzle and workpiece to be marked.Can just be marked by the polarity of exchange nozzle and workpiece to be marked, namely metal electrodeposition is removed to gauge point instead of from gauge point galvano-cautery.By the color and luster adopting the electrolyte of heterogeneity can change indicia patterns.
The invention has the beneficial effects as follows, pattern and character can when each mark stochastic generation as required, not by the restriction of template, the information such as sequence number and date-time can be comprised easily.

Detailed description of the invention
In FIG, computer (101) runs control program, instruction is sent to stepper motor driver (102) by stube cable, on the X-axis stepper motor (104) that the output of stepper motor driver (102) is connected respectively to cross slid platform and y-axis stepper motor (123).Slide unit movable plate (122) is connected with shower nozzle (106) by insulation connecting plate (105).The control program that computer (101) runs, command adapted thereto is sent to program control electrolysis power (103) by stube cable simultaneously, the positive pole of program control electrolysis power (103) exports and is connected to conduction backing plate (108), and negative pole exports and is connected to electrolyte nozzle (106).Electrical contact is kept between conduction backing plate (108) and workpiece to be marked (107).Cell liquor pump (118) is by electrolyte suction inlet (113) and through filter (116) suction electrolyte (115), and electrolyte (115) arrives flowmeter (120) via pipeline.Pipeline after flowmeter (120) is provided with Pressure gauge (121) with monitor force.After Pressure gauge (121), electrolyte (115) continues transported to electrolyte nozzle (106) by pipeline.There is an aperture at the tip of electrolyte nozzle (106), electrolyte (115) via small hole injection on workpiece to be marked (107).The electrolyte (115) ejected is collected to prevent from splashing by baffle plate (119).The electrolyte (115) collected turns back in electrolytic bath (114) via pipeline (112) and continues to recycle.
In the process of mark, drive nozzle to carry out two-dimensional scan by program above workpiece to be marked by conputer controlled cross slid platform, be switched on or switched off output by program by conputer controlled line lock simultaneously.When power supply disconnects, can not leave a trace in the surface of the work region below nozzle, and when power supply is connected, the surface of the work region below nozzle can leave corresponding vestige because of electrolytic effect.After two-dimensional scan completes, the pattern needed for can obtaining at surface of the work.
