For solving the problems of the technologies described above, the technical solution used in the present invention is as follows: wet cutting of a kind of SMT template laser and the equipment that detects, the process equipment of the wet cutting of used SMT template laser, comprise cutting head, nozzle, step up the mechanism of Zhang Ping SMT template automatically, described process equipment adopts and moves two gantry structures that drive, Y-axis seesaws and drives X-axis and seesaw, and the Z axle is fixed on the moving plate of X-axis, and move plate with X-axis and carry out side-to-side movement, on the moving plate of Z axle cutting head is installed, cutting head has the coaxial-type nozzle; Spray cooling water by this nozzle synchronously to the cut point zone of cutting head below.
 
Wet cutting of SMT template laser and the method that detects comprise following several steps:
A) the SMT template is fixed on the work stage of laser cutting machine,
B) with stepping up Zhang Ping mechanism the SMT template is stepped up Zhang Ping;
C) CCD linear scan assembly moves to cutting zone in X, Y direction, and to scanning position, the top crossbeam moves to non-cutting area simultaneously;
D) adjust the cutting head of laser cutting machine, aim at the cut point zone, and the nozzle by the cutting head next door is to cut point area spray cooling water; The SMT template is carried out laser cutting;
E) cutting is finished back waste material dust exhaust apparatus and is withdrawed from board cleaning waste residue automatically, and the lamp box above crossbeam presses down, and with the upper glass face of following CCD linear scan assembly the SMT that is cut is clamped, and enters scanning mode at this moment and scans detection; File, position, direction, the positive and negative judgment task of cutting, scanning are finished automatically by main control computer;
F) move on the lamp box behind the end of scan, the CCD scan components moves down;
G) the waste material dust exhaust apparatus has been cleared up waste residue and is got back to and return to cut state in the equipment body;
H) if detect steel disc few hole is arranged, main control computer carries out the perforations adding cutting.
In the technique scheme, described laser cutting machine adopts the coaxial-type nozzle, the coaxial-type nozzle is hollow cylindrical, there is photoelectric sensor mount pad 3 upper end, photoelectric sensor 1 and photoelectric sensor focusing knob 2 be located at photoelectric sensor mount pad 3 above, below the photoelectric sensor mount pad 3, coaxial water jet device inside is provided with 45 0Speculum 4 is with 45 0On the cylindrical sidewall of speculum 4 correspondences, be provided with lighting source 5, be provided with laser generator 6,45 below the lighting source 5 0Be provided with focus lamp 7 below the speculum 4; the cylindrical sidewall of focus lamp 7 correspondences is provided with focus lamp focusing differential head 8; be provided with protective glass 9 below the focus lamp 7; protective glass 9 following for having double-deck nozzle 11; water jet 12 passes through between nozzle 11 double-deckers, and nozzle 11 is connected with high service unit 10 by the water inlet on the sidewall 13.
