Background technology
Laser Processing because of advantages such as its concentration of energy, the contactless modes of action, is being widely used in production all departments as a kind of new manufacturing process.For the drilling of high hardness material or other special materials, the laser drilling is a kind of effective and efficient manner.The laser drilling can be divided into laser boring and cut the hole.When punching was meant laser and material effects, its application point was static with respect to material, until perforation, realized the preparation of micro hole; Cut the hole and be meant by cutting mode, make laser walk circular trace on material, the cut-out material is realized perforation, is used for preparation than large diameter hole.
At present to use more in the material drilling be the pulse perforating device to laser, described a kind of high speed boring appts of thin material as patent CN 1327897A, the Focused Optical system that basic ideas are laser beams that laser instrument is sent by the adjustable parallel arranged of a cover shines separate single and sweeps away on the thin material of mechanism of paper and implement punching.Because of its Focused Optical system of fixing along all corresponding cover in each row hole of material movement direction that is perforated, when increasing the columns in hole, must increase the Focused Optical system of similar number, make device structure numerous and diverse, be unsuitable for multiple row hole, wide format punching requirement especially.Promptly be used in face punching in a narrow margin, because its every suit Focused Optical system is in a single day fixing, the position is difficult for adjusting, and promptly column pitch is difficult for adjustment.And its each light-beam position is fixed, and can not do circumferential motion, promptly can not realize the adjustable of the cutting of large diameter hole and aperture on a large scale.
Laser is used for material when punching, mainly contains static punching and dynamic two kinds of punching forms of punching, and is static and dynamically be in static with the object that is perforated when punching or mobile status is distinguished.For the punching of metal and thick material, the laser action time that needs is long, generally adopts static punching; Punch for then the employing dynamically of nonmetal thin material more.When dynamically punching, the location in hole becomes the key factor of drilling quality.In report in the past, location for material generally is to adopt step motor control to walk to expect length, or makes marks on the material that is perforated, and positions by the certification mark position, for the on-stepper motor production line or be difficult to do the rapidoprint of position mark, said method is infeasible.
In addition, the present laser drilling device of reporting generally is used for drilling thin, flexible to yew paper, plastics package paper etc., no adhering material.For thicker thin material, as cloth, fabric; Inflexible thin material is as organic sheet plastic; Sticking thin material, as medical proof fabric, materials such as adhesive plaster also do not have good drilling method and equipment.
Summary of the invention
The object of the present invention is to provide the method and apparatus of the nonmetal thin material laser drilling of continuous operation under a kind of dynamic situation that can be applicable to automatic production line, can be used for wide format or punching or cut the hole on the nonmetal thin material of face in a narrow margin, the hole evenly distributes or is arranged in style, the size and the density in hole are adjustable, and stable performance, easy maintenance.What particularly point out is that the object of the present invention's processing can also be non-sheet metal except common flexible thin material, medical proof fabric, special materials such as adhesive plaster.
For achieving the above object, a kind of method of nonmetal thin material laser drilling the steps include:
(1), selects punching or cut the drilling mode in hole according to the drilling requirement; And, control laser power, and adjust size, density and the pattern in hole by the movement locus of control beam deflection system by control device by the program parameter of control device is set;
(2) movement velocity of online detection machined material and pass to control device;
(3) when movement velocity during, utilize laser to carry out drilling, in cutting the hole process, constantly obtain the movement velocity of material greater than the toggle speed set, and displacement calculating compensation rate in real time, adopt beam deflection system to make compensation correction in real time according to compensating signal; When material movement speed is lower than termination speed, stop cutting the hole, and latency speed, finish until task.
Realize the equipment of said method, comprise laser instrument, beam deflection system and walk materials device that beam deflection system and laser instrument are positioned on the same light path, constitute the drilling device jointly; Control device links to each other with beam deflection system, and this equipment is provided with the velocity sensor that links with control device.
The said equipment can comprise two covers or the above drilling device of two covers, and each drilling device places respectively on the little supporting bridge, and places on the support by supporting bridge, the laser action district is become on machined material evenly distribute.
The said equipment can also be provided with dust exhaust apparatus in periphery, laser action district, and links to each other with filter by blower fan.
The present invention has the following advantages:
(1) can be by adjusting control program, select punching or cut the drilling mode in hole, and by the control program parameter being set, size, density and the pattern in control laser power, hole.When the hole working method is cut in employing, can realize that the aperture is adjustable on a large scale.
(2) in certain speed range, can guarantee that the drilling pattern does not change with the variation of line speed.No matter promptly for production line at the uniform velocity, or the speed change production line, owing to there is the control computer that the automatic real-Time Compensation of galvanometer scanning system is proofreaied and correct, the spacing in hole, size and pattern remain consistent.
(3) obtain displacement signal by near the precise displacement sensor that is arranged on the drilling zone, offer computer and dynamically determine the drilling position, this localization method not only equipment is simple, be applicable to multiple material, and need on by the drilling material, not add any telltale mark, in process of production not to being caused waste by the drilling material.
