Abstract
The utility model belongs to a packaged goods marking device, in particular to an automatic device for marking date, number, trademark and other symbols on the packaged goods on conveyor belt by CNC laser. The laser flying marking machine is composed of power supply 1, X,Y scanning galvanometer, a focus lens 4 and a laser 5, wherein the laser 5 is connected with power supply 1, a laser bean that radiated by the laser 5 passes through the X,Y scanning galvanometer and the focus lens 4, and then which is reflected and focalized to one point in the central section of the conveyor belt. The utility model is characterized in that: the device comprises a photoelectric positioning device as well 6, which is horizontally arranged at the two sides of the feed end on the conveyor belt, a computer is respectively connected with the laser, the scanning galvanometer and the photoelectric positioning device through the interface card.
Description
Technical field: the utility model belongs to the marking device of package goods, belongs to digital control laser is stamped information symbols such as date, numbering, trade mark to the package goods that moves on the conveyer belt automatics or rather.
Background technology: the method for on packaged commodity, stamping information such as date, numbering, trade mark at present, most ink-jetting styles that adopt laser marking method is also arranged, but the product that goes on the market at present mostly are static mark or constant speed correction, rather than the correction of testing the speed in real time, the mark scope is also little.
The utility model content: the purpose of this utility model is: overcome the prior art shortcoming, a kind of laser marking on the fly machine is provided, it can be revised real-time, makes the font of getting keep straight; Especially without limits, can print the speciality character string that exceeds sweep limits to string length.
The purpose of this utility model is to realize like this, the laser marking on the fly machine, comprise power supply 1, scanning galvanometer X, Y, focus lamp 4, laser instrument 5, wherein, laser instrument 5 links to each other with power supply 1, the laser beam that sends by laser instrument 5 by scanning galvanometer X, Y, focus lamp 4, reflect and focus on the conveyer belt stage casing a bit, it is characterized in that: also comprise photoelectric positioning apparatus 6; Photoelectric positioning apparatus 6 levels are placed in the feed end both sides of conveyer belt 7, and computer links to each other with laser instrument, scanning galvanometer, photoelectric positioning apparatus respectively by interface card.
Computer receives and handles the signal that photoelectric positioning apparatus 6 sends by control system, whether the control laser instrument shoot laser.
Described photoelectric positioning apparatus receives diode by Light-Emitting Diode and photoelectricity and forms, move to the light that assigned address shelters from light emitting diode in case treat the workpiece of mark, because photodiode can't receive the light of Light-Emitting Diode at this moment, therefore send signal.Interface card knows that promptly workpiece moves to assigned address like this, accurately controls laser instrument and begins mark, thereby play the effect of location.
Described laser marking on the fly machine, also comprise photoelectric encoder 2, photoelectric encoder 2 is positioned at a side of machined material conveyer belt 7, the axle of photoelectric encoder links to each other with the conveyer belt power transmission shaft, the electrical signal of photoelectric encoder inserts the interface card of computer, signal that computer control system receives and processing photoelectric encoder 2 sends and the corrective action of controlling galvanometer in view of the above.
To nonmetal packing material mark CO
2Laser instrument is to metal packaging box mark acousto-optic modulation solid YAG laser instrument.By the controlled motion of X, Y galvanometer, the utility model can be got English alphabet, Arabic numerals, Chinese character and some icons.
Photoelectric encoder provides the signal of the velocity magnitude and the direction of motion in real time for computer, make galvanometer produce additional deflection, to revise the distortion that font is produced owing to movement of objects.
The utility model compared with prior art has following advantage: 1, owing to photoelectric encoder 2 is installed in the discharge end of conveyer belt, photoelectric encoder is monitored in real time to the movement velocity of machined material in the machined material traveling process, and the data that transmit a movement velocity every 10 microseconds are given computer so that revise galvanometer deflection, so the font of getting is always straight; Can adapt in the accurate mark of high-speed mobile object.2, again since control system with the end of mark initiating terminal,, marked by laser to preceding by the back on the machined material, so without limits to string length along with the conveyer belt band machined material by under the focus lamp as mark.3, because photoelectric positioning apparatus is arranged, the bright dipping of control laser mark on mobile object makes character accurately be printed on the precalculated position constantly.Laser printing does not need printing ink in addition, can not embrocate, and is permanent anti-fake mark.
Description of drawings
Fig. 1 is the utility model structural representation; Among the figure, 1 power supply, 2 photoelectric encoders, X, Y scanning galvanometer, 4 focus lamps, 5 laser instruments, 6 photoelectric positioning apparatus, 7 conveyer belts.
Fig. 2 is the logic diagram of the utility model control device.
The specific embodiment
Referring to accompanying drawing 1, the laser marking on the fly machine is characterized in that: comprise power supply 1, photoelectric encoder 2, scanning galvanometer X, Y, focus lamp 4, laser instrument 5, photoelectric positioning apparatus 6; Wherein, laser instrument 5 links to each other with power supply 1, the laser beam that sends by laser instrument 5 by scanning galvanometer X, Y, focus lamp 4, reflect and focus on the place in conveyer belt stage casing, photoelectric encoder 2 is positioned at discharge end one side of conveyer belt 7, the feed end both sides of photoelectric positioning apparatus 6 rapidoprint conveyer belts 7, computer links to each other with laser instrument, scanning galvanometer, photoelectric encoder, photoelectric positioning apparatus respectively by interface card, receive and handle the signal that photoelectric encoder 2 and photoelectric positioning apparatus 6 send by control system, whether the motion of control galvanometer and laser instrument shoot laser.
Referring to accompanying drawing 2, at first, operating personnel set parameters on computers and import character and the figure that needs processing, computer passes to interface card with signal, when workpiece to be processed moves to the focus lamp below with conveyer belt, photoelectric receiving diode provides commencing signal to interface card, and interface card sends commencing signal at this moment and makes the laser instrument bright dipping.Simultaneously interface card begins per 10 microseconds and reads the rate signal that photoelectric encoder provides, and in real time revised control signal is passed to scanning galvanometer X, Y respectively, and self status signal fed back to computer, make the operator can be on screen real-time monitored to the duty of processing.
