Specific implementation mode
The present invention provides a kind of method marking water level line scale on pot liner using laser, to make the mesh of the present invention
, technical solution and effect it is clearer, clear, the present invention is described in more detail for the embodiment that develops simultaneously referring to the drawings.
It should be appreciated that the specific embodiments described herein are merely illustrative of the present invention, it is not intended to limit the present invention.
The equipment for marking water level line scale in pot liner of the embodiment of the present invention, as shown in Figure 1, including：Electrical control division
1, laser 2, beam expanding lens 3, galvanometer system 4, optical focus camera lens 5, workbench 6.Wherein, the electrical control division 1 is used for
To laser provided energy power supply, the way of output of laser beam is controlled.The laser 2 is used to be laser processing of materials surface
Light source is provided；Preferably Standard Machine optical fiber marking machine, impulse wave a length of 1055nm-1075nm, pulsewidth 100-140ns are put down
Equal power is 20W.The light that the beam expanding lens 3 is used to send out lasing light emitter expands, and improves the transmission characteristic of laser so that it is more preferable
Laser is converged to material surface by ground.The galvanometer system 4 includes X galvanometers and Y galvanometers, by scan module and optical reflecting lens
It is composed, for driving optical mirror slip to carry out the finger that gauche form movement gives laser according to control software using scan module
Carry out telltale mark is set in positioning.The optical focus mirror 5 is used to make laser facula of the laser beam in a certain flat focus to point
Characteristic is consistent, the optical focus mirror of preferably F525.Pot liner is placed when the workbench 6 is for laser machining mark.
It is provided in an embodiment of the present invention a kind of to mark water level line scale on pot liner using laser based on above equipment
Method, as shown in Fig. 2, including：
Step A, pot liner is moved to the edge in camera lens mark effective range, and adjusts the focus of camera lens in pot liner
Inner wall on；
Step B, the inner wall of adjustment pot liner tilts to predetermined angular；
Step C, the predetermined map file track of scanning laser, and according to predetermined map file track, control laser stepless action is in processing
Specified area inner wall carries out mark, completes the water level line scale mark of pot liner.
Further, in the present embodiment, in the step A, by adjusting the height of camera lens, make pot including the focus of camera lens
On.
Further, in the present embodiment, in the step A, by increasing block on the lifting body of laser marking machine,
Adjust camera lens height.
Further, in the present embodiment, in the step A, after pot liner is positioned over the vertical position in optical center, then
It is horizontal to the left or to move right to camera lens mark effective range inward flange.
Further, in the present embodiment, in the step B, the predetermined angular is 30~75 °.
Traditional common laser reference mark and pattern are all 90 degree of perpendicular actings of laser incident angle in workpiece surface, are swashed
The absorptivity highest of light.But the characteristics of due to pot inner-tube structure, there are certain height and incident angle, to make laser to absorb
The highest incident angle of rate just cannot achieve completely on scale mark, because the vertical angle of pot can block laser and add
Work track will be realized in pot liner mark, it is necessary to by pot liner slant setting.If the angle of inclination of pot liner was arranged
It is big or too small, it can make pot liner that can not be in the effective range of laser marking, scale just can not completely be got to a pot liner
On.Therefore the range of tilt angles of pot liner needs between 30 degree to 75 degree.When it is implemented, pot liner is placed mirror first
Behind the vertical position in head center, then horizontal to the left or move right to camera lens mark effective range inward flange；Then, by laser
Increase block on the lifting body of marking machine, adjusts camera lens height, camera lens focus is made to fall on pot inner wall；Then adjustment pot is put
30~75 ° of angle allows laser stepless action to specify area inner wall, completion to beat in processing by the predetermined map file track of scanning laser
Mark.It is noted that liner pot wall top edge is avoided to block laser processing track running route when adjusting position, ensure that laser highest is inhaled
Yield makes up burnt body problem and causes energy will not phenomenon.
Further, in the present embodiment, further include before the step A：
Step A1, laser marking machine is debugged, parameter is set.When it is implemented, the parameter tune of the machine light marking machine
Adjusting range is：Impulse wave a length of 1055nm-1075nm, pulsewidth 100-140ns.
Further, in the present embodiment, further include before the step B：
Step B1, depth of focus is adjusted to grow to preset range.Water level line scale lowest point and highest point are not located at same horizontal line
When, laser is beaten on stainless-steel pan, and water level line scale lowest point and highest point just have a difference in level, in order to make laser
This difference in height is made up, depth of focus will be adjusted by, which needing, grows to preset range.When it is implemented, the preset range of the depth of focus length is
8mm~10mm.It is preferred that a length of 9mm of depth of focus.
Further, in the present embodiment, further include before the step A1：
Step A2, pot liner is fixed by fixture.Pot liner is fixed and adjusted by fixture, can prevent a pot liner pine
Processing error caused by dynamic, improves yield rate.
The present invention is using laser in the method in pot liner label water level line scale, compared with existing technique, the present invention
Method is without the processing of any subsequent technique, and the effect shading processed is smooth, and character boundary is clearly clear, surface
Impulse- free robustness (as shown in Figure 3).The method of the present invention time is short at low cost, can significantly improve working efficiency.
It should be understood that the application of the present invention is not limited to the above for those of ordinary skills can
With improvement or transformation based on the above description, all these modifications and variations should all belong to the guarantor of appended claims of the present invention
Protect range.
