Abstract
The invention provides an airflow lamination linear track transmission machining device and relates to a machining device which is used for connecting workpieces by using a transmission technology. The device comprises a machining head, wherein the machining head is capable of providing airflow and a ray bundle which can be projected to an upper layer. Therefore, within a functioning range that the airflow generates a pressure, machined material on the upper layer and machined material on a lower layer are compressed together tightly; an air outlet of the machining head is not in direct rigid contact but actually soft contact with the upper surface of a machining area to be machined of the machined material on the upper layer; and therefore a variety of disadvantages caused by pressure of the rigid contact are solved fundamentally. At this time, the ray with sufficient energy penetrates through machined material on the upper layer to be projected to the joining plane of the upper layer machined material and the lower layer machined material, and a great deal of heat energy is generated on the joining plane so as to melt and connect machined material on the upper layer and the machined material on the lower layer. After being cooled, the machined material on the upper layer and machined material on the lower layer are connected together.
Description
Technical field
The present invention relates to a kind of processing unit (plant) that utilizes through-transmission technique that workpiece is coupled together.This device has the tubular processing head, and said tubular processing head can provide air-flow and the beam of investing machined material surface, upper strata.Therefore, make use at the pressure that air-flow produces, the upper strata machined material is closely pressed together on lower floor's machined material.At this moment; The beam that carries enough energy sees through the upper strata machined material; Project tight pressing place of upper strata machined material and lower floor's machined material; And in this tight pressing place by efficient absorption, change heat energy into, this heat energy is welded together upper strata machined material and lower floor's machined material.After the cooling, upper strata machined material and lower floor's machined material are connected.
Technical background
In through-transmission technique, the contact-making surface that has workpiece to be connected to be adjacent to each other, fusing under the effect of laser beam realizes in the cooling subsequently connecting under the effect of pressure each other, and the Plastic Welding method of this use laser beam obtains generally open.In these class methods importantly: need closely press together two-layer workpiece up and down in the welding process.
Patent document EP1405713B1 discloses a kind of laser aid.In this laser aid; Accurately on the position at laser beam incident place, workpiece is pushed to pointwise; In the zone of incident place of laser beam, pushing, perhaps the lines transverse to the relative motion of laser beam push workpiece planarly.Two-layer like this, up and down workpiece closely presses together and effectively welding.
Patent document 200910139101.6 discloses a kind of laser aid with hold-down roller of swing.In this laser aid, the transparent roll that can rotate has focussed laser beam and the effect that compresses work piece simultaneously.
Disclosed similar patented technology common feature is must be through the direct mode application of force of contact, so that materials at two layers up and down to be connected is closely pressed together on together, thereby guarantees the effective welding of materials at two layers up and down.This will bring following problem: at first, thrust must directly contact through rigidity and pass to upper layer of material by the part that plays pressuring action, the tight pressing of upper layer of material and subsurface material then.(part that especially plays pressuring action passes to thrust the contact of upper layer of material) all is the rigidity contact because twice contact, is difficult to the contact of realization face, thereby is difficult to guarantee the effective welding of materials at two layers up and down.200910139101.6 the laser aid of disclosed band hold-down roller because hold-down roller has a radius size, when processing proceeds to the inner corner trim place that has less than the hold-down roller radius, can not be realized effectively compressing, and possibly cause the welding breakpoint.Secondly; The part that plays pressuring action is passing to thrust in the process of upper layer of material; Two problems possibly appear: the one, and long-time running causes dust, greasy dirt etc. to adhere on the part that plays pressuring action, has influence on the even distribution of the steady and thrust of operation.For 200910139101.6 disclosed hold-down rollers; These burs also possibly have influence on the spotlight effect of hold-down roller; Make the portion of energy of laser beam be dispersed into other direction, can't guarantee that the weld place obtains enough laser energies, thereby influence the effect of welding.The 2nd, long-time running possibly bring wearing and tearing, and the part and the upper layer of material surface that cause playing pressuring action stay cut.For 200910139101.6 disclosed hold-down rollers, these cuts possibly have influence on the spotlight effect of hold-down roller.
Summary of the invention
Must adopt rigidity to compress the problem of bringing in order to overcome existing this type of technology, task of the present invention is to propose a kind of scheme, utilizes this scheme can guarantee to make and obtains uniform thrust up and down between materials at two layers.
By the present invention, this task is resolved through a kind of linear track transmission of air-flow pressing processing unit (plant) with the said characteristic of claim 1.Other favourable design can be resolved from dependent claims.
According to solution provided by the present invention be: the linear track transmission of air-flow pressing processing unit (plant) is processed first-class part by air inlet pipe, tubular and is formed; Air inlet pipe is communicated with the tubular processing head; Tubular processing head lower end sets out gas port, and the shape of gas outlet can be made the aperture of circular hole, square hole or other shapes.During the work of the linear track transmission of air-flow pressing processing unit (plant); The gas outlet from directly over aim at the upper strata machined material region surface to be processed; Vertical or the approaching region upper surface to be processed that vertically acts on the upper strata machined material of the air-flow that flows out from the gas outlet; Thereby the region upper surface to be processed to the upper strata machined material produces a pressure, and this pressure is closely pressed together on the to be processed zone of upper strata machined material between lower floor's machined material.At this moment; The ray that carries enough energy that throws in the tubular processing head sees through the upper strata machined material; Project the zone to be processed between upper strata machined material and the lower floor's machined material; And be absorbed into heat energy in this zone, rapidly upper strata machined material and lower floor's machined material are welding together.At this moment, the tubular processing head is under the driving of drive system, and the track along design in advance moves away gradually, and levels machined material weld obtains cooling and solidifies, and upper strata machined material and lower floor's machined material are firmly coupled together.
Because the pressure force between upper strata of the present invention machined material and the lower floor's machined material is realized by the air-flow transmission; The region upper surface to be processed of the gas outlet of tubular processing head and upper strata machined material not directly rigidity contact; Be actually a kind of flexibility and exert pressure, thereby can fundamentally solve the various disadvantages that the rigidity contact is exerted pressure and brought.
