Description

Laser marking machine

Technical Field

The utility model relates to a marking machine technical field especially relates to a laser marking machine.

Background

Laser marking refers to the permanent marking of various material surfaces with a laser beam. When the laser marking machine works, workpieces with different thicknesses need to be processed, so that the laser marking machine needs to have a function of adjusting the working focal length. The focusing of a common laser marking machine is completed by manually rotating guide sleeves at four corners of a workbench so as to lift the workbench, but the method is inconvenient to adjust and is not suitable for processing heavier workpieces. The long-term use even causes the platform of the laser marking machine to twist, and the processing precision is reduced.

Therefore, in summary, a laser marking machine capable of automatically measuring the focal length is a technical problem to be continuously solved in the industry.

SUMMERY OF THE UTILITY MODEL

An object of the utility model is to provide a laser marking machine to overcome prior art's is not enough.

In order to achieve the above purpose, the technical scheme of the utility model is as follows:

the embodiment of the utility model discloses laser marking machine, including workstation, stand, laser marking head, ruddiness emitter and controller, its characterized in that: the laser marking device comprises a stand column, a laser marking head and a CCD sensor, wherein the stand column is used for supporting the laser marking head, the laser marking head is used for marking a light spot on a workbench, the laser marking head can vertically move along the stand column, the CCD sensor is fixedly arranged beside a lens of the laser marking head, and the red light emitter and the CCD sensor are electrically connected with the controller.

The utility model relates to an among the preferred scheme, still including set firmly in the other distance sensor of camera lens of mark is beaten to laser.

Further, the distance sensor is electrically connected with the controller.

Further, the lower end of the distance sensor is flush with the lower end of the lens of the laser marking head.

In another preferred embodiment of the present invention, the device further comprises a driving motor electrically connected to the controller, the driving motor drives the laser marking head along the vertical column moves vertically.

Furthermore, the stand is square column, is equipped with one or more perpendicular linear guide on its four perpendicular faces respectively, laser marking head cover is located on the stand, and with the guide rail phase-match.

Compared with the prior art, the utility model has the advantages of:

1) the utility model provides a pair of laser marking machine can move laser marking head perpendicularly and make and penetrate the facula size on the workstation through it and change thereupon, and when the facula that detects until the CCD sensor was minimum, the difference in height between distance sensor measuring lens bottom and the workstation is the focus of this laser marking machine promptly. The controller is connected with each detection and driving part, can automatically complete the work of focusing, reduces the labor intensity of workers and has high working efficiency. Meanwhile, the distance between the lens and the workbench is adjusted in a mode of moving the laser marking head without being influenced by a workpiece to be processed borne on the workbench, and the applicability is wide compared with the adjustment through moving the workbench.

2) Preferably, the utility model provides a pair of laser marking machine still is equipped with distance sensor, can be at this distance of good back automatic measure of focus regulation, labour saving and time saving.

Drawings

In order to more clearly illustrate the technical solutions in the embodiments of the present invention, the drawings used in the description of the embodiments will be briefly described below.

Fig. 1 is a schematic view of a laser marking machine disclosed in an embodiment of the present invention;

fig. 2 is a logic connection diagram of a laser marking machine disclosed in the embodiment of the present invention.

Detailed Description

The technical solution in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention.

As shown in fig. 1-2, the embodiment of the utility model provides a laser marking machine, including workstation 1, stand 2, laser marking head 3, be located laser marking head 3 ruddiness emitter 4 and controller 5, still including setting firmly in laser marking head 3's camera lens 31 other CCD sensor 6 is used for detecting the facula of penetrating the red light on workstation 1 through laser marking head 3, distance sensor 7 is used for detecting the distance between camera lens 31 and the workstation 1. The lower end of the distance sensor 7 is flush with the lower end of the lens 31 of the laser marking head 3.

The stand 2 is square column, is equipped with a vertically linear guide 21 on its four perpendicular faces respectively, and laser marking head 3 cover is located on stand 2 to with the guide rail 21 phase-match. The drive motor 8 drives the laser marking head 3 to move vertically along the guide rail 21. The number and shape of the linear guide rails 21 arranged on the vertical surface of the upright post 2 and the vertical surface on which the guide rails 21 are fixedly arranged can be adjusted according to the conditions of the weight of the laser marking head 3, the lifting distance of the laser marking head and the like.

Wherein the CCD sensor 6, the distance sensor 7, the red light emitter 4 and the driving motor 8 are electrically connected to the controller 5.

When the utility model works, the red light emitter 4 emits red light, the red light is emitted to the workbench 1 through the lens 31 of the laser marking head 3 to form a light spot, and the CCD sensor 6 receives the information of the size, the brightness and the like of the light spot and inputs the information to the controller 5; the controller 5 controls the driving motor 8 to drive the laser marking head 3 to move up and down along the guide rail 21, the size of the light spot is changed along with the movement, and the controller 5 sends a command to enable the driving motor 8 to stop acting until the size of the light spot reaches the minimum value; at this time, the information of the distance between the bottom of the lens 31 and the surface of the table 1 detected by the distance sensor 7 is the focal length f of the lens 31.

The utility model has the characteristics of adjust convenient and fast, labour saving and time saving, extensive applicability.
