Description
Technical field
Laser marking machine technical field is the utility model is related to, particularly a kind of laser marking machine automatic focusing mechanism.
Background technology
Because laser marking device needs to be adjusted to just enter from a distance from workpiece surface fixation by F- θ field lenses at work
The normal work of row, therefore laser marking machine is required for carrying out this adjustment before work.
Existing adjustment mode is mainly by manual operation.First, workpiece is placed on below F- θ field lenses, by one end of ruler
It is fitted on the surface for needing to process；Meanwhile lean against ruler on the scanning galvanometers of fixed F- θ field lenses, then shake lift
The crank of structure, F- θ field lenses is adjusted up and down to the distance of finished surface, the work on the mark line and ruler on scanning galvanometer
Focal length graduation mark overlaps, and completes focal adjustments work.
The working method relies on artificial visual graduation mark to determine focus, position error easily occurs.When adjustable range compared with
, it is necessary to which artificial shake crank for a long time when remote, consume one's strength.Ruler for positioning belongs to self-contained unit, easily goes out active
Situation.Because ruler needs directly to contact with workpiece, easily workpiece surface is caused to damage.Due to the crank of lowering or hoisting gear
Apart from working region farther out, adjustment work could be completed by needing two people to coordinate when workpiece is larger.
The content of the invention
The utility model technical issues that need to address are to provide a kind of laser marking machine automatic focusing mechanism of automation.
To solve above-mentioned technical problem, laser marking machine automatic focusing mechanism of the present utility model, including F- θ field lenses,
The F- θ field lenses are arranged on lifting arm front lower portion, and lifting arm front end sidepiece is fixed with laser range sensor, institute
Laser range sensor is stated with controller input to be connected；Also include lifting column, the lifting column is fixed on pedestal；
Elevating mechanism is provided with the lifting column.
Further, the elevating mechanism includes motor, the motor input and controller output end phase
Connection；Riser guide is fixed with the lifting column, is provided with lifting slider on the riser guide, the lifting slider with
Motor output end is connected；The lifting arm is fixed on lifting slider.
Further also include manual control button, the manual control button is connected with controller input.
After said structure, the utility model has used laser range sensor to detect F- θ field lenses to workpiece mark
The distance in face, eliminate error during artificial reading scale value；In addition, need not directly it be connect with workpiece surface in the course of the work
Touch, eliminate the risk of disfiguring workpiece.
Brief description of the drawings
The utility model is described in further detail with reference to the accompanying drawings and detailed description.
Fig. 1 is the structural representation of the utility model laser marking machine automatic focusing mechanism.
In figure：1 is motor, and 2 be mounting bracket, and 3 be laser range sensor, and 4 be F- θ field lenses, and 5 be workpiece, and 6 are
Manual control button, 7 be lifting column, and 8 be riser guide, and 9 be lifting slider, and 10 be lifting arm
Embodiment
As shown in figure 1, laser marking machine automatic focusing mechanism of the present utility model, including F- θ field lenses 4, the F- θ field lenses
4 are arranged on the front lower portion of lifting arm 10, and the front end sidepiece of lifting arm 10 is fixed with laser range sensor 3, described to swash
Ligh-ranging sensor 3 is connected with controller input, and laser range sensor 3 arrives the mark of workpiece 5 for detecting F- θ field lenses 4
The distance in face.Present patent application also includes lifting column 7, and the lifting column 7 is fixed on pedestal；On the lifting column 7
It is provided with elevating mechanism.
Further, the elevating mechanism includes motor 1, the input of motor 1 and controller output end
It is connected；Riser guide 8 is fixed with the lifting column, lifting slider 9, the lifting are provided with the riser guide 8
Sliding block 9 is connected with the output end of motor 1；The lifting arm 10 is fixed on lifting slider 9.
Operation principle of the present utility model is as follows：The workpiece 5 for needing mark is placed on the lower section of laser range sensor 3
On pedestal, laser range sensor 3 detects the distance that F- θ field lenses 4 arrive the mark face of workpiece 5, and detection data then are transferred into control
Device processed, controller control motor 1 to drive lifting slider 9 to move up and down after reading the data, so that will by elevating mechanism
The F- θ field lenses 4 of the front end of lifting arm 10 are adjusted on suitable operating position.Laser range sensor 3 has been used to detect F- θ
Field lens 4 arrives the distance in the mark face of workpiece 5, eliminates error during artificial reading scale value.Elevating mechanism is driven using motor, section
Regulated efficiency is also improved while human-saving.It need not directly be contacted with workpiece surface in the course of work, eliminate damage work
The risk of part.
Further, in order to meet special laser marking demand, present patent application is provided with manual adjustment mode, also
Including manual control button 6, the manual control button 6 is connected with controller input.Wanted when there is special mark distance
When asking, by pressing " rising " on controller, " decline " button can manually adjust F- θ field lenses 4 to the surface of workpiece 5 away from
From.
Although the foregoing describing specific embodiment of the present utility model, those skilled in the art should manage
Solution, these are merely illustrative of, and various changes or modifications can be made to present embodiment, without departing from original of the present utility model
Reason and essence, the scope of protection of the utility model are only limited by the claims that follow.
