Description
Technical field
The present invention relates to Laser Jet technical fields, and in particular to a kind of omnidirectional laser marker.
Background technique
Laser Jet refers to prints the information such as text or pattern in product surface in the form of laser index carving, such as product
Date of manufacture, lot number, sequence number, model etc., it is now widely used for all trades and professions.
In the application of Laser Jet, position and angle for printing, generally by the object of adjustment laser marker
The relative position of stamp object in the template file of position and adjustment stamp software is managed to set.After setting, when each stamp, code
Position and angle be just fixed and invariable, and in actual production, position and direction when every product enters stamp area are all
Different, therefore the effect actually printed is: the type information position and angle all deviations above product are larger.
For this problem, at present there are two the solutions in actual production: (1) not limiting the position and direction of stamp
Or it reserves wider range and ensures that product enters the orientation angle in stamp area as far as possible；(2) production is directed to the mould of specific products
Tool or fixture before one product of every printing, manually put product, put in place by the position and angle of mold (fixture) restriction.
Summary of the invention
Present invention seek to address that above stamp position and the uncertain problem of angle, propose a kind of omnidirectional Laser Jet
Machine.
In order to solve the above technical problems, the present invention is achieved by the following scheme:
A kind of omnidirectional laser marker, including rack, feed system, visual identifying system, Laser Jet system and
Control system, the feed system include product container and product conveyer belt, are used for product charging and product on the rack
The front end of transmission, the product conveyer belt is equipped with product sensor；The visual identifying system and Laser Jet system are set to machine
Above frame, visual identifying system includes front and back sides vision collecting instrument and omnidirectional vision collecting instrument, for capture product image, with
Standard picture compares, calculates the position of current production and the offset of angle, and the Laser Jet system has laser marker, uses
According to the product offset coordinates and angle got, adjusting product space and being product stamp, the control system includes electricity
Brain hardware and control software, control system is connect with visual identifying system, Laser Jet system, product sensor, for experiencing
Process instruction is sent to visual identifying system after the trigger signal sent to product sensor, and visual identifying system is obtained
Data are handled, and are converted including the offset to view-based access control model coordinate system, are converted to based on Laser Jet system
Coordinate values send stamp instruction for Laser Jet system.
Preferably, the omnidirectional laser marker further includes recovery system, and the recovery system includes recycling branch
Frame and recovery tube, for recycling the product of omnidirectional vision collecting instrument disqualified upon inspection.
A kind of omnidirectional Laser Jet method, includes the following steps:
(1) product is delivered into the stamp area of rack by feed system；
(2) control system receives the trigger signal from product sensor, sends process instruction to visual identifying system；
(3) visual identifying system is handled, including is captured product image, compared with standard picture, calculates current production
Position and angle offset, processing result sends back control system by visual identifying system；
(4) control system handles the data of acquisition, changes including the offset to view-based access control model coordinate system
It calculates, is converted to the coordinate values based on Laser Jet system；
(5) control system issues stamp request to Laser Jet system；
(6) offset coordinates and angle of the Laser Jet system according to acquisition, the stamp template file of mobile laser marker
In object's position, including horizontal, vertical movement and rotation；
(7) Laser Jet system carries out marking, notifies control system after the completion.
It further, further include after the completion of step (8) Laser Jet, the omnidirectional vision collecting instrument of visual identifying system is examined
Underproof product is measured to be recycled by recovery system.
Compared with prior art, the device have the advantages that are as follows: the present invention can replace the mode manually put, real
Show position accurately Laser Jet.To greatly improve production efficiency and stamp quality.
