The specific embodiment
Referring to Fig. 1,2, the embodiment of the invention adopts the computing machine of storage mark program to carry out mark by the control of numerical control integrated circuit board with laser generator bonded assembly laser scanner, and carries out following steps:
1) initialization system is provided with the mark information such as pictorial trademark that mark is used in the mark program that computing machine prestores;
Whether 2) normal by hardware sensor checking system state, if mal is reported to the police and waited for and getting rid of, all normal then numerical control integrated circuit board drives the motor movement of belt conveyor;
Whether 3) hardware sensor detects has product to put in place, arrive the mark position as product, call the mark program and begin to read mark information, the mark date, sequence number, program is according to the mark date, the region-position code of serial number data part character is searched this character position in character library, read character phasor coordinate information, according to character boundary, at interval, coordinate position, and pictorial trademark, generating the mark Vector Message, pecorrection is because the figure deformation that mark causes, generate final mark Vector Message, from article one vector, program begins interpolation to be calculated, and finishes vector motion, every interpolation once, send the interpolated point coordinate D/A converter to generate analog quantity driving laser scanner movements, judge whether that simultaneously the point of beating with the front overlaps, as overlapping, skip this point, up to having beaten all final mark Vector Message;
4) mark is finished, and computing machine signaling belt conveyor moves, repeating step 3.
System carries out initialization earlier, i.e. laser power zero setting, numerical control integrated circuit board are put the optical gate of reset mode, all I/O delivery port zero setting, laser generator and closed, and in the mark program that computing machine prestores the mark information such as pictorial trademark that mark is used are set then.The input dialogue frame that mark information specifically can enter the mark program is set, by keyboard input mark starting point coordinate, select font from dialog box, input mark literal, be kept at trade mark on the hard disk with mouse drawing on the screen or call then with document form, edit mark content, position, size, and preserve.After finishing the mark parameter and being provided with, hardware sensor begins the checking system state, the flow that comprises the water of laser marking machine cooling system, the temperature of water, line voltage, power supply three-phase electricity phase shortage, Laser Power Devices and laser works state, present embodiment adopts the mirror-vibrating laser scanning device, also needs the scanning galvanometer mode of operation.If these state of the system have mal, export a low level by the I/O delivery port, turn-off system power supply, drive warning circuit and report to the police, normal then motor movement by numerical control integrated circuit board driving belt conveyor.Hardware sensor detects when product puts in place on the driving band, and computing machine calls the mark program and begins mark, has beaten the back and continue to have transmitted, and withdraws from or system breaks down and withdraws from up to user's control.
