More specifically：
In step sl, steel bar 3 is placed on stepping platform 1, all tantalum wires 4 on the good steel bar 3 of precheck
Whether level is neat, that is, allows the circumferential section of all tantalum wires 4 to be highly in unanimously, if it not, first by whole levels pair of tantalum wire 4
Together, it is to avoid indivedual warpages of tantalum wire 4, cause demoulding effect bad.
Meanwhile, the method for the laser fixed fire scanning is that the tantalum wire 4 for stepping to fixed fire position 6,7 is entered by laser head
Row demoulding, the fixed fire position 6,7 is the projected position of the laser head.Fixed fire position 6,7 can be determined in advance, general, point
The position penetrated is positioned as close to smooth piece of 5 end faces, but laser facula can not be allowed to be irradiated to smooth piece 5, it is to avoid made during laser-induced thermal etching
Smooth piece 5 of etching in pairs.
In step s 2, it is that subregion demoulding is carried out to the circumferential surface of tantalum wire 4 during laser-induced thermal etching demoulding,
As shown in figure 5, the periphery of tantalum wire 4 is divided into four equal cambered surface regions of correspondence angle altogether, be respectively first area 41,
Second area 42, the 3rd region 43 and the 4th region 44, wherein, it is 90 ° that the region angle of each periphery, which is preferably,.
In the step S3, journey is gone to carry out contraposition demoulding, backhaul pair to the first area 41 in the stepping platform 1
The second area 42 carries out contraposition demoulding；Laser is set to carry out fixed point fixed fire in fixed fire position 6,7 using the control of laser software
Scanning, laser head is more than the radius of (or at least equal to) described tantalum wire 4, laser head in the distance of the radial scan of the tantalum wire 4
The length of demoulding is treated for the tantalum wire 4 in the length of the axial scan of the tantalum wire 4；Before laser fixed fire scanning is carried out, in advance
The focal length of laser-induced thermal etching is adjusted, it is ensured that the energy of laser can meet the effect for etching away the oxide-film of tantalum wire 4 just, then by steel
Bar 3 is fixed on can be on the workbench of stepping, the movement of stepping from left to right of the driving steel bar 3 of stepping platform 1, and tantalum wire 4 is one by one through too drastic
The fixed fire position 6 of light, laser triggering etching completes to scan etching to the first area 41 of the periphery of tantalum wire 4；Wait stepping platform
1 driving steel bar 3 is moved to limit on the right-right-hand limit, after being etched to all tantalum wires 4, then runs from right to left automatically again, is working as
Tantalum wire 4 one by one step motion to laser fixed fire position 7 when, laser now again fixed fire position 7 triggering etching, complete to tantalum wire 4
The laser fixed fire scanning etching of the second area 42 of periphery.
In step s 4, after completing to first area 41 and the demoulding of second area 42, steel bar 3 is overturn into fixation, is
Step S5 prepares.
In step s 5, journey is gone to carry out contraposition demoulding to the 3rd region 43 in the stepping platform 1, backhaul is to institute
State the 4th region 44 and carry out contraposition demoulding.Stepping platform 1 continues to drive the stepping from left to right of steel bar 3 movement, and tantalum wire 4 passes through one by one
The fixed fire position 6 of laser, laser triggering etching completes to scan etching to the 3rd region 43 of the periphery of tantalum wire 4；Stepping is waited to put down
The driving steel bar 3 of platform 1 is moved to limit on the right-right-hand limit, after being etched to all tantalum wires 4, then runs from right to left automatically again,
When tantalum wire 4 one by one step motion to laser fixed fire position 7 when, laser now again fixed fire position 7 triggering etching, complete to tantalum wire
The laser fixed fire scanning etching in the 4th region 44 of 4 peripheries.Thus by the subregion demoulding in this four regions, 360 ° can be reached
Comprehensive film takes off effect, it is ensured that whole tantalum wire 4 needs in the length and whole circumferential surfaces of demoulding that thoroughly demoulding is done
Only.

Be fixed on by magnetic fixture on stepping platform 1, be easy to steel bar 3 overturning commutation, the stepping platform 1 for straight line stepping
Module (is not illustrated) in figure, and the laser head of laser fixed fire scanning element 2 can adjust fixed fire scanning direction and angle, can conveniently control
The scanning pattern of laser.
When carrying out demoulding to all regions, laser head is more than the tantalum wire 4 in the distance of the radial scan of the tantalum wire 4
Radius, laser head for the tantalum wire 4 treats the length of demoulding in the length of the axial scan of the tantalum wire 4, to first area
41 go to second area 42 carry out demoulding when, now the angle of laser head can carry out angle adjustment between 0-180 °, specifically
When stepping platform 1 has etched first area 41, to be moved in the driving steel bar 3 of stepping platform 1 at limit on the right-right-hand limit, completing laser
The conversion of brilliance degree, to adapt to de-filming process of the laser head to second area 42；The 4th is being gone to the 3rd region 43 accordingly
When region 44 carries out demoulding, also need to complete above-mentioned laser angle conversion.
In the present embodiment, it is desirable in the clean surrounding environment processed, specific embodiment, more than 10,000 grades are may be selected
Dust proof workshop, and surrounding in demoulding in the processing unit installs a draft hood additional, can avoid demoulding chip to ring
The influence in border, with avoid fragmentary chip may Electrostatic Absorption on tantalum wire 4.
The beneficial effect that the present embodiment is compared with the prior art includes：
The present embodiment uses machinery to be to scrape film process to compare compared in the prior art, with laser to the circumference table of tantalum wire 4
Oxide-film on face is etched, and substantially increases the operability of demoulding, further, in order to reach good membrane removal
Effect, the present invention uses subregion method for demoulding, can reach 360 ° of comprehensive demoulding effects, clean and thorough.
In preferred scheme, during demoulding is carried out using laser subregion, controlled using stepping platform 1 on steel bar 3
All tantalum wires 4 be stepped through the fixed fire position of laser demoulding one by one, effectively complete the membrane removal to all tantalum wires 4, go journey
The membrane removal in the region 43 of first area 41 and the 3rd can be completed, backhaul can complete the membrane removal in the region 43 of second area 42 and the 3rd, adopt
There is rotatable laser head so that the scanning pattern of laser is adjustable, demoulding effect is more preferable.
