Description
Technical field
The utility model belongs to field of mechanical technique, relates to a kind of making net by laser equipment, and particularly a kind of driving steadily, the driving mechanism of the laser engraving machine that net precision processed is high.
Background technology
Dyeing plain net on the textile stamp be one of the most frequently used method, usually needing print pattern to be on the textile first produced on plain net, and then print on textile, on plain net, pattern-making adopts light reaching the film method usually, ink-jet photoresist process, wax spray is photosensitive, and direct exposure method.
Light reaching the film ratio juris is the colloid that coating comprises photoactive substance on plain net, and after low temperature drying, parcel covers style black and white film, exposes, then develop under uviol lamp.Ink-jet and the photosensitive ratio juris of wax spray utilize spray black ink or black wax to substitute black film covering not need photosensitive partial pattern.Direct exposure method adopts laser directly to carry out photosensitive on plain net by pattern, do not need to use any medium.
Conventional film is photosensitive, ink-jet or Wax spraying method exist that operation is many, the cycle is long, efficiency is low, cost is high, use the problems such as medium pollution environment, and half tone poor definition fineness is inadequate, and expressive ability is not enough.Therefore those skilled in the art's utility model net making method of direct exposure, adopts laser explosure net, does not use any medium, except saving time, the advantage such as cost, making precision be high, also directly or indirectly can reduce environmental pollution.Its principle of work is coated with photoresists on net base, the co-wavelength laser instrument that use can allow photoresists photosensitive, by its light beam after optical system arranges, under flower pattern information controls, online colloid is exposed, realize flower pattern information in the reduction of online dot matrix, then carry out developing, fixing, flushings, the subsequent handling such as oven dry complete the making of flower net.Due to laser explosure is the handover information of design, light beam can realize micron order focus point after arranging, each focus point is as the point of in dot matrix image process, and multi-laser can form array, multiple spot is arranged in line and improves laser work efficiency, can export high-precision dot pattern fast.Because of the circle that each focus point is all smooth, in actual production, the plain net that the photoresist process that the flower pattern printed of the plain net that uses this equipment to manufacture is traditional than ever makes is more accurate, clear.
But for this method of being undertaken exposing by laser instrument, need by laser instrument shuttle-scanning on web plate, utilize in the dot matrix of laser pulse operate lasers on half tone the light forming pattern that exposes to the sun, this just needs the stable movement of laser instrument and meticulous, and the exposure of guarantee design accurately.What adopt in prior art is that Dual-Servo Motor drives driving screw mandrel to drive frame to scan along half tone.If but namely the nonsynchronous phenomenon of Dual-Servo Motor existence operation can cause laser scans to occur deviation, causes half tone exposure quality poor.
Summary of the invention
The purpose of this utility model there are the problems referred to above for existing technology, proposes one and operate steadily, the driving mechanism of the laser engraving machine that precision is high.
The purpose of this utility model realizes by following technical proposal: a kind of driving mechanism of laser engraving machine, comprise frame, it is characterized in that, described frame is provided with crossbeam, described frame both sides are provided with the servomechanism installation driving crossbeam lengthwise movement, described servomechanism installation comprises two longitudinal rails be arranged in frame, the screw mandrel that described frame is provided with drive motor and is connected with motor output shaft, pedestal is arranged with outside described screw mandrel, described base sleeve to be connected on longitudinal rail and can along slide, described beam erection is on two pedestals, described frame both sides are provided with the displacement transducer detecting base motion track, described drive motor controls its action by control system, described displacement transducer is electrically connected with control system and sends position signalling continuously to control system.
The driving mechanism of this laser engraving machine, by arranging two servomechanism installation in frame both sides, pedestal is driven to run by leading screw and nut mechanism, the pedestal that can realize crossbeam two ends synchronously drives, displacement transducer is set in frame both sides, detects in real time the sliding position of pedestal, and feed back in control system and compare, the stability that servomechanism installation runs can be promoted further, ensure the precision that drive unit drives.
In the driving mechanism of above-mentioned laser engraving machine, described displacement transducer is grating scale.Grating scale is arranged at frame sidepiece, after pedestal moves a certain distance, detect its displacement by grating scale, and it is high that it detects degree of accuracy.
In the driving mechanism of above-mentioned laser engraving machine, described displacement transducer is magnetic railings ruler.
Grating scale has highly sensitive, not by the advantage of effect of magnetic influence, but if its surface produces spot, then easily affect induction sensitivity and the degree of accuracy of grating scale, for the occasion that accuracy requirement is not high, magnetic railings ruler can be adopted to replace grating scale as displacement transducer.
In the driving mechanism of above-mentioned laser engraving machine, described drive motor adopts servomotor.
In the driving mechanism of above-mentioned laser engraving machine, described drive motor adopts stepper motor.
Compared with prior art, the driving mechanism of this laser engraving machine arranges by frame two ends the movement that two servomechanism installation realizes crossbeam, its operation stability is high, operation deviation is little, meanwhile, by displacement transducer examinations pedestal run location, compare with control system, realize closed-loop control, can ensure that the lengthwise movement of crossbeam is accurate, and be in controllable state all the time.
