An embodiment of parameter inscribed in coin product literal, as shown in table 1.
Table 1 micro text laser engraving parameter
(3) molding of thumbnail line and impression operation
The thumbnail line combines with molding and stamping technique, is its basis that can be applied to the coinage technology, have only by with the combining of coinage technology, just can be applied to coinage.Because thumbnail line section is that internal or female screw structure and the figure line slope angle that is " U " shape is almost zero degree, so the crux point that the thumbnail line combines with molding and stamping technique comprises:
Determine position and the figure line height of thumbnail line on mould;
Determine that the thumbnail line adopts internal or female screw structure or positive line structure on product;
Thumbnail line structure is to the requirement of Mould Machining.
Coin product with two groups of micro texts is tested, and its micro pattern is designed to:
Micro text adopts two groups of single line bar Chinese characters;
The individual character font size is 0.3mm * 0.5mm, and carving depth is 0.03mm * 0.05mm;
Adopt the internal or female screw structure on the product.
Adopting single line bar word is to guarantee that literal is clear, complete in limited dimensional space.
Should consider to improve imitation difficulty when determining individual character font size and carving depth, consider the clear and complete of literal again simultaneously, have certain structure intensity simultaneously.
Adopting the internal or female screw structure for micro text on coin and souvenir badge product still is positive line structure, the present invention has carried out careful comparative analysis and test: because laser engraving machine can only be carved system internal or female screw word, uniformity in order to ensure the product micro text, if adopt the characters cut in relief structure on the product, then need on the internal or female screw mould, carry out laser carving word, need process internal or female screw mould → two grand master patterns, two grand master patterns → die to turn over for twice to press and once impress micro text and just can transfer on the product.And adopting the internal or female screw structure, micro text can be carved on two grand master patterns, only need once turn over pressure and impress operation through two grand master patterns → die promptly to can be transferred on the product, by contrast, has saved internal or female screw mould-two grand master pattern and has turned over the pressure operation.Owing to turn over the slight disappearance that pressure can cause micro text, adopt the internal or female screw structure to compare the pressure of turning over that has also promptly reduced by a micro text with the positive line structure of employing and lack, therefore have certain superiority.In addition, consider the sticking to mould problem that copper alloy base cake usually exists when impression, micro text is that positive line structure is more safer, reasonable than internal or female screw structure on die, so the embodiment of the invention 1 determines that micro text adopts the internal or female screw structure on product.
Owing to adopt thumbnail line structure,, answer in the real work: 1) strengthen turning over the surface inspection of pressing operation, avoid " pressure pad " defective of micro text as far as possible in order to ensure the quality of micro text in the Mould Machining process; 2) adopt vacuum heat treatment process quenching die, avoid the oxidation and the decarburization of micro text structure; 3) careful operation in the polishing process avoids micro text to be bruised.
(4) make the laser engraving positioner
In order to ensure the commemorative coin consistency of product, the position of two grand master pattern micro texts of necessary each engraving of assurance and the uniformity of figure line height.Because the CEO-DP2000 laser engraving machine does not provide processing and positioning device, therefore must and make positioner and guarantee by design.
The upper end object lens of reading microscope and eyepiece and fixed support thereof are dismantled,
Scroll chuck is fixed in the pallet in the heart, like this, just can realize by engraved die in XOY plane translation or rotate and adjust, and the minimum of a value of adjusting is 0.01mm or 0.1mm.
The thin transparent film that certain rigidity is arranged is lain against two master surface and is fixed in the elsewhere, engraving character on film by adjusting two grand master pattern positions, is observed the relative position of literal on two grand master patterns then in advance, lift the sheet that removes photoresist then, on two grand master patterns, carve.
Above-mentioned test shows that this localization method positioning accuracy adopts the commemorative coin product two grand master pattern positions of this kind method engraving accurate, can satisfy the consistency of product requirement basically about 0.05mm.
