Specific embodiment
Embodiment of the present utility model is described below in conjunction with accompanying drawing.
Understand that the laser marking machine 1 in the present embodiment includes referring to Fig. 1：Workbench 2；For generating the laser light of laser
Road 4；Implement the lifting support 3 of lifting with the laser marking head 5 of 4 integrally connected of laser optical path and to laser optical path 4.Workbench
The workpiece W for treating mark is placed on 2.Laser marking head 5 implements mark to the mark face of workpiece W.
As shown in Figures 1 and 2, laser marking machine 1 also includes visible light projection unit 6 and position control device 8.Beat in laser
The both sides of header 5 are respectively fixedly installed a visible light projection unit 6.As shown in Fig. 2 visible light projection unit 6 project separately down can
Depending on light.Above-mentioned visible light (LB) inwardly lateral deviation puts certain angle.So, when laser marking head 5 is in specified altitude, visible light
Can be focused into as shown in Figure 2 a bit.
Lifting support 3, can be according to from controller from the well known devices such as guide rail, electrode and ball-screw are provided with it
8 signal, controls the lifting of laser optical path 4 and laser marking head 5.
Controller 8 includes computing device 84 as controller main body, display 82, multiple for what is be operated manually
Button 81 and keyboard 83.Computing device 84 at least includes a circuit board.Controller 8 is connected with lifting support 3 by cable etc.,
According to the result of calculation of the computing device 84 of controller 8, laser optical path 4 and the laser marking head 5 being connected with lifting support 3 is controlled
Rise or fall.Controller 8 controls the work of laser optical path 4 and laser marking head 5 simultaneously, omits which in the present embodiment
Explanation.
Multiple buttons 81 include making the rising that laser optical path 4 and laser marking head 5 rise or fall via lifting support 3
Button and decline button.Thus, it is possible to manually manipulate the raising and lowering of laser marking head 5.Due to visible light projection unit 6
The both sides of laser marking head 5 are fixedly installed on, visible light projection unit 6 also follows laser marking head 5 to rise or fall.Therefore, grasp
Make personnel and be able to confirm that while rise/fall button 81 is operated, by visual observation to be projected by visible light projection unit 6
Visible light (LB) whether focus on the mark face of workpiece W.
Specifically, as shown in Fig. 2 when operator visually confirm the mark that visible light projection unit 6 projects workpiece W
When having spacing between the point (being 2 points of left and right in the present embodiment) of the visible light on face, operation rises button 81, is lifted and is swashed
The height of light labelling head 5, until two point focusing of left and right of visible light.At this moment, rising button 81 is stopped operation, to laser marking head
5 are positioned.
In the above-described embodiment, by the focusing of the point of the visible light on the mark face of the visual workpiece W of operator, handss
The height of dynamic operation laser marking head 5.
Alternatively, visible light monitoring unit 7 is also set up on laser marking head 5.Visible light monitoring unit 7 is installed
On the position not interfered with visible light projection unit 6, it is connected with controller 8 by above-mentioned cable.
Visible light monitoring unit 7 includes minisize pick-up head 71 and image processing part 72.Minisize pick-up head 71 can for example be adopted
CCD minisize pick-up heads.Minisize pick-up head 71 shoots the point of visible light on the mark face of workpiece W, and forms image.Image processing part
72 moment were processed to above-mentioned image, and will be sent for controlling the result that laser optical path 4 and laser marking head 5 are lifted
To controller 8.
Specifically, image processing part 72 is imaged to the image shot by minisize pick-up head 71 by known technology,
And imaging data is sent to into controller 8.According to imaging data, controller 8 judges whether visible light is focused in mark face.Specifically
Decision procedure for example with following manner：In the image of above-mentioned image, the center of the point of visible light distance to each other is low
When prescribed distance, judge that visible light is focused on, so as to position to laser marking head 5.
Used as another embodiment of the present utility model, above-mentioned visible light projection unit 6 each projects the visual of different colours
Light.As shown in Fig. 3 A and Fig. 3 B, the visible light projection unit 6 for being arranged on 5 both sides of laser marking head each projects different colours
Visible light.
Visible in Fig. 3 A and Fig. 3 B, left side visible light projection unit 6 projects red visible light (R), and right side visible light is thrown
Penetrate portion 6 and project blue visible light (B).So, according to the point (R) of red visible light and the point (B) of blue visible light in mark
Relative position on face, it becomes possible to simply judge laser marking head 5 be apart from workpiece W excessively closely or too far.Specifically, such as
Shown in Fig. 3 A, when point (R) of the visible light on mark face, (B) are respectively in the identical of the visible light projection unit 6 for projecting the visible light
During side, then can judge that laser marking head 5 is excessively near apart from workpiece W immediately, only need to manually or automatically control laser and beat
Header 5 is mobile to the direction (being ascent direction in present embodiment) away from workpiece W.In addition, as shown in Figure 3 B, when visual
Point (R) of the light on mark face, (B) when the opposite side of visible light projection unit 6 of the visible light is projected, equally can respectively
Judge that laser marking head 5 is excessively near apart from workpiece W immediately, laser marking head 5 only need to be manually or automatically controlled near work
The direction (being descent direction in present embodiment) of part W is mobile.
In such manner, it is possible to simply judge that 5 opposite piece W of laser marking head was that closely or too far, it is right to be effectively improved
The work efficiency of the positioning of laser marking head 5.
In the present embodiment, visible light employs red and blue visible light.But, embodiment party of the present utility model
Formula is not limited in the visible light of both colors.For example (can be included using the combination in any of following varicolored visible light
Its wavelength is represented in number)：Bluish violet (405nm), blue (445nm, 460nm, 473nm), green (532nm), yellow (589nm)
With red (635nm, 650nm) etc..
In addition, when monitoring the focusing of visible light using minisize pick-up head 71, the concept and range of the visible light can be included
Infrared ray and the wave-length coverage of ultraviolet that naked eyes be can't see.
