Detailed description of the invention
Below in conjunction with accompanying drawing, the utility model is described in detail:
Refer to Fig. 1 to Fig. 4, the structural representation of its a kind of laser marking machine 100 provided for the utility model and internal structure schematic diagram.Described laser marking machine 100 comprises cabinet 101, laser instrument, switch 20, reflective mirror 40, beam expanding lens 50, controller and heat abstractor 70.Described laser marking machine 100 also comprises and being arranged on described cabinet 101 to arrange the support member 102 of described switch 20.Described laser instrument comprises laser generator 10 and galvanometer scanning system 30.It is envisioned that according to model, the isoparametric difference of power of described laser generator 10, may also need corresponding power supply change-over device normally to work to drive described laser generator 10.Now, described switch 20 by the electric connection directly controlling the electric connection between external power source and described laser generator 10 or control between power supply change-over device and this laser generator 10, thus can control opening or closing of laser generator 10.The above-mentioned mounting structure of described laser marking machine 100 and power supply are arranged to be all technology known by those skilled in the art and not to be the utility model emphasis, is not just repeating at this.
Described cabinet 101 has cabinet wall 1011.Described cabinet wall 1011 surrounds cavity volume 1012.Described cabinet wall offers the through hole 1013 for shoot laser.Described through hole 1013 is communicated with described cavity volume 1012.Described cabinet 101 also comprises upper cover 103 and lower cover (not shown) is located on described cabinet wall 1011 with lid to form seal chamber.The following touch-screen 61 carrying out controlling for external input signal in described control device can be arranged on upper cover 103.Described cabinet 101 can adopt metal material or plastics to make.Described cabinet 101 can for cuboid be at utmost to mate the shape of described generator 10.Described through hole 1013 can be circular hole.Area when described through hole 1013 is circular hole is greater than the cross-sectional area of the laser beam of final outgoing.The area of described through hole 1013 can provide higher level of protection again under being specifically arranged so that the prerequisite of laser outgoing as far as possible.In the present embodiment, described through hole 1013 is the cuboid hole matched with described support member 102.
It should be noted that, the radial direction of described through hole 1013 and the axial relative of described through hole 1013.The axis of described through hole 1013 and the direction of final laser emitting.The direction that the radial direction of described through hole 1013 is namely vertical with the axis of this through hole 1013, any direction namely on the face vertical with the radial direction of described through hole 1013.
Described support member 102 treats mark object for supporting, and the laser projection penetrated to make described laser generator 10 is needing on mark article.Described support member 102 can be the structures such as support, gripper shoe or fixture.In the present embodiment, described support member 102 is treated mark object to can make simultaneously and conveniently arranges described switch 20 and play a protective role to this switch 20, and described support member 102 is support housing.Described support housing has supporting surface 1021.This supporting surface offers opening 1022.Described support member 102 is arranged on through hole 1013 side.Described through hole 1013 made to enter laser beam irradiation scope when mark object is placed on this support member 102.Arrange it is envisioned that described support member 102 is arranged with the distance of this through hole 1013 in the radial direction along described through hole 1013 according to required marking region.This supporting surface 1021 offers opening 1022.Treat mark object and handled easily for the ease of placing, described opening 1022 is set to vertically upward, and this opening 1022 is positioned at the below of the through hole 1013 of described cabinet 101.Angle between described support member 102 and described through hole 1013 is set to 60 degree to 100 degree, is preferably 90 degree.
Described laser generator 10 is arranged on described cabinet 101 with shoot laser to treat etching mark on mark object.Described laser generator 10 sends high energy laser.Can burn when this laser projection is on object, corrosive substance, thus leave the permanent marking.For example, the laser of described laser generator 10 outgoing can corrode the plastics treated on mark object, paper surface layer thus leave corresponding permanent marks.In the present embodiment, described laser generator 10 adopts the carbon dioxide laser generator that efficiency is high, stablized.
See also Fig. 5, described switch 20 is arranged on the power supply circuits that power supply and described laser generator 10 be electrically connected.Described switch 20 controls the opening and closing of described laser generator 10.Described switch 20 can mechanical switch or inductive switch.Preferably, described switch 20 is delay switch, touch-switch or optoelectronic switch.When described switch 20 is touch-switch, this touch-switch is arranged in the support housing of described support member 102, and protrudes from the supporting surface 1021 of described support housing.Described touch-switch induction is treated the change of the pressure that mark object brings and triggers.When described switch 20 is photoelectric sensor switch, this photoelectric sensor switch can stretch out or just to this opening 1022, thus the change of the light that mark object causes is treated in induction.In the present embodiment, treat mark object for the ease of placing and simplify the operation, the opening 1022 of described support member 102 is vertically arranged upward, and described opening 1022 is positioned at the below of the laser of described laser generator 10 outgoing.Now, as long as will treat that mark object is placed on the signal intensity that described opening 1022 can change to inductive switch 20, thus this switch 20 is made to open described laser generator 10.Further, described laser generator 10 is set to shoot laser in the horizontal direction.Now, horizontal emission laser is vertical with the direction of the opening 1022 of described support member 102, is not only convenient to laser ablation and treats mark object but also facilitate intersecting of the induction region of described switch 20 and the shoot laser of described laser generator 10.
