Description
Technical field
The utility model relates to the laser welding technology of thermoplastic, specifically is meant the optical-fiber laser welder based on the thermoplastic of vibration mirror scanning.
Background technology
The plastics laser welding technology is a kind of noncontact solder technology in the ascendant.Compare with other Plastic Welding method, it have noncontact, airtight, water-tight, speed of welding is fast, precision is high, weld strength is high, non-trimming, no residue, friction, thermal stress minimum, be easy to control, plurality of advantages such as flexibility is good, adaptability is good.The plastics laser weld often adopts the method for transmission welding, is about to two plastic components overlapping putting together up and down, and plastics are to laser-light transparent at the middle and upper levels for it, and lower floor's plastics have higher absorptivity in the laser wave strong point.Two plastic components are applied with certain pressure make its tight contact, when laser sees through upper strata plastics heating to laser-light transparent and has the lower floor plastics of certain absorptivity, the heat that produces impels two plastic moltings of tight contact, because the diffusion of material finally forms instantaneous infiltration weld seam at the interface.
The method for laser welding of plastic material commonly used has the welding of sequence type contour, welding synchronously, scanning welding, mask welding at present.
(1) sequence type contour welding: laser moves and makes its fusing along the outline line of Plastic Welding layer, with plastic layer bonding together gradually; Perhaps will be moved the purpose that reaches welding along fixing laser beam by interlayer.The contour speed of welding is slower, and efficient is lower, is not suitable for batch process.
(2) welding synchronously: from the laser beam of a plurality of diode lasers, by optical element with laser beam reshaping, laser beam is directed on the outline line of weld layer, and produces heat in the commissure, thereby makes the whole profile line melt simultaneously and bond together.Speed of welding is the fastest synchronously, but lens and fibre bundle need regular maintenance, and the output balance of diode laser is an a difficult problem.When using fibre bundle, the specific purpose tool cost is very high, and installation time is long.
(3) scanning welding is with a pair of servo-controlled galvanometer control laser beam, and laser beam repeatedly scans the welding position fast, makes the temperature echelon of welding point every bit increase, and has a few until whole welding joints almost to reach fusing point simultaneously and begin to melt.It has advantages such as speed is fast, accurate positioning.
(4) mask welding: laser beam positions, melts and adhered plastics by template, and this template only exposes very little, an accurate welding position of following plastic layer.Laser beam is not only to there being the masked part heating that covers on the goods.This procedure is simple, but efficient is low, and a large amount of laser is dissipated and slatterns.Mask needs often to safeguard and change.Installation time is generally longer, and weld interval is shorter.
The lasing light emitter of plastics laser weld use at present is generally CO2 laser instrument, Nd:YAG laser instrument and semiconductor laser.The CO2 laser instrument, it can produce the light wave of 10600nm, absorbed by plastics easily, but its ability that sees through plastics is relatively poor, mainly is applicable to the thin-film material welding.The wavelength that the Nd:YAG laser instrument produces is 1064nm, and the plastics that contained particular fillers or pigment easily absorb, but the volume of Nd:YAG laser instrument is bigger, and is not too convenient when using on production line.The wave-length coverage that semiconductor laser produces is between 800～1000nm, and this butt welding fetches the most effective energy area of saying so.Its compact conformation can be installed on the automation equipment very easily, is easy to realize the miniaturization and the portability of laser instrument.Because its power output is less, be applicable to that the welding laser power requires lower occasion, as the precision welding of small plastic device.The CO2 laser instrument can not lack flexible with the optical fiber coupled transfer in sum; Nd:YAG laser instrument volume is bigger, and is not too convenient when using on production line; The power output of semiconductor laser is less, can only weld small-sized plastic device.
