Description
Technical field
The invention belongs to laser marking machine machinery equipment field, and focusing auxiliary system is overlapped in particular to a kind of dotted line
System and its auxilary focusing method.
Background technology
CO2Laser marking machine, that is, CO 2 laser marking machine is to utilize CO2Gas is beaten for the laser galvanometer of working media
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 discharged
Glow discharge is generated in pipe, gas is made to release wavelength as 10.64um laser, after laser energy is amplified, through vibration mirror scanning and
Focus lamp focus on after, under the control of computer and laser marking control card, can acording to the requirement of user be carried out on workpiece image,
The marking of word, number, lines.
The Chinese invention patent of Patent No. ZL201320465787.X discloses one kind and expands conjunction beam integrating device, packet
It includes first expand component, second expand component and one and close tread assembly, which is fixedly attached to described first and expands group
Part and second expand component between, a perforation passed through for visible ray is offered on the conjunction tread assembly, which is used for will
Visible ray 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 becomes
For visible ray.
The Chinese invention patent of Patent No. ZL201220678252.6 discloses a kind of laser and galvanometer labelling head
Connection structure, including expanding mirror support, neck fixed frame and neck connector, the neck fixed frame expands mirror support mounted on described
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

Achieve the purpose that the collimation of accurate effectively adjusting light beam, and enable to realize between laser and laser galvanometer and freely tear open
It unloads.
CO of the prior art2Laser marking machine is usually that the laser beam that laser generates passes through laser marking head, by
The luminous point that laser marking head guides laser beam that focus lamp is passed through to pool a very little carries out mark on a surface of an, and
To ensure best mark effect, laser marking head must remain a fixed distance between body surface, we claim
For focal length, each CO2The focal length of laser marking machine is determined by focus lamp, and above-mentioned light beam converges after focus lamp
Into 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 best 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
It above one adjustable for height stent, then chooses several objects and is placed on fixed platform, then measure focus lamp with ruler
To the distance in object mark face, mark is then carried out, the height of equipment is raised and lowered again according to mark situation, again mark,
Compare the effect of successively mark twice, height is then varied multiple times again and repeats the above process, until best mark location is found,
Then measure this distance with ruler and record, because the focus lamp of every equipment is different, therefore to the focal plane of every equipment into
Row determine 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
To CO2The use of laser marking machine causes inconvenience.In consideration of it, the present invention, which provides a kind of dotted line, overlaps focusing auxiliary system
And its auxilary focusing method.
