Description
Technical field
The invention belongs to laser marking machine machinery equipment field, are overlapped focusing auxiliary system in particular to a kind of dotted line
System and its auxilary focusing method.
Background technique
CO2Laser marking machine, that is, CO 2 laser marking machine is to utilize CO2Gas is that the laser galvanometer of working media is beaten
Mark machine. CO2Laser is with CO2Gas is medium, by CO2Discharge tube is filled with other auxiliary gases to add high pressure on the electrode, is put
Glow discharge is generated in fulgurite, so that gas is released wavelength 10.64um laser, after laser energy is amplified, through vibration mirror scanning
After focusing with focus lamp, under the control of computer and laser marking control card, figure can be carried out acording to the requirement of user on workpiece
The marking of picture, text, number, lines.
The Chinese invention patent of Patent No. ZL 201320465787.X discloses one kind and expands conjunction beam integrating device,
Component is expanded including first, second component and one is expanded and closes tread assembly, which is fixedly attached to described first and expands
Component and second expands between component, and a perforation passed through for visible light is offered on the conjunction tread assembly, which is used for
It will be seen that light is overlapped with laser.This conjunction beam integrating device that expands can be such that visible light beam is overlapped with laser beam, so that laser
Become visible light.
The Chinese invention patent of Patent No. ZL 201220678252.6 discloses a kind of laser and galvanometer labelling head
Connection structure comprising expand mirror support, neck fixed frame and neck connector, the neck fixed frame, which is mounted on, described expands mirror support
On, one end of the neck connector, which is set to, to be expanded between mirror support and neck fixed frame.This connection structure will be original non-adjustable
The connection type of section thoroughly changes, and the fixation position of mirror support and neck fixed frame can be expanded by adjusting bolt adjusting, thus
Achieve the purpose that the accurate collimation for effectively adjusting light beam, and enables to realize between laser and laser galvanometer and freely tear open
It unloads.
CO in the prior art2Laser marking machine is usually that the laser beam of laser generation passes through laser marking head, by
The luminous point that laser marking head guides laser beam to pool a very little across focus lamp carries out mark on a surface of an, and
To guarantee best mark effect, laser marking head must be remained between body surface one it is fixed at a distance from, we claim
Be focal length, each CO2The focal length of laser marking machine is determined by focus lamp, and above-mentioned light beam converges after focus lamp
At the luminous point of a very little be focus, the horizontal plane where focus is focal plane, this plane is that we do not see and touch not
, it is the appellation of physicist's visualization.
The plane that object is marked must necessarily be placed on focal plane, can just obtain optimal mark effect in this way.But practical behaviour
In work, the focal plane determination process of every equipment is extremely cumbersome.General way is first by CO2Laser marking machine is mounted on one
It above a height-adjustable bracket, then chooses several objects and is placed on fixed platform, then measure focus lamp with ruler and arrive
Then the distance in object mark face carries out mark, the height of equipment is raised and lowered again according to mark situation, again mark, than
Then height is varied multiple times again and repeats the above process for the relatively effect of successively mark twice, until finding optimal mark location, so
This distance is measured with ruler afterwards and is recorded, and because the focus lamp of every equipment is different, therefore the focal plane of every equipment is carried out
Determination all need to repeat the above process, even and same machine, replace focus lamp after, still need to repeat the above process, this is just right
CO2The use of laser marking machine causes inconvenience.In consideration of it, the present invention provide a kind of dotted line be overlapped focusing auxiliary system and
Its auxilary focusing method.
