Description

A kind of for cutting large format steel-sheet elastic fixing structure
 
Technical field
The present invention relates to the laser equipment field, be specifically related to a kind of fixed structure.
 
Background technology
In electron trade, usually adopt sheet metal to make the mould of printed circuit board (PCB), need to be at large scale Thin Stainless Steel surface of steel plate cutting special pattern, steel plate thickness is below 0.3mm, and plate size is in the 600*600mm left and right.
In prior art, have the remarkable advantages such as cut quality is good, cutting speed fast, safety non-pollution due to laser cutting, sheet metal adopts laser cutting usually.When adopting the laser cutting sheet metal, the XY platform drives cutting head and does plane motion, and steel plate is placed to the cutting head below, shine cut material surface after the laser beam line focus, in cutting process, must guarantee that the distance of laser beam waist and surface of steel plate is relatively stable, as shown in Figure 1, when the variable in distance between laser cutting head 1 and steel plate 2 is larger, can cause the situation that cutting is not saturating or cut quality descends, finally cause scrapping.
In the precise laser cutting process, size after laser beam 11 focuses on is at 20 ~ 30um, now laser beam 11 depths of focus are in tens micrometer ranges, if steel plate 2 apparent heights change, will cause the relative distance on laser beam 11 waists and steel plate 2 surfaces to change, therefore, the device of fixation steel plate 2 need to guarantee that steel plate 2 flatness are less than below 0.5mm.The square law device complexity of tradition fixation steel plate 2, when larger, be difficult to even up steel plate 2 when steel plate 2 both sides parallelism errors.
