Abstract
The utility model relates to a laser head for a laser processing machine, comprising a laser head shell, a focusing mirror and at least one group of protective mirrors, wherein the protective mirrors are arranged at the down stream of a light path of the focusing mirror, and the protective mirrors and the focusing mirror are coaxially arranged. The protective mirrors can be panel lenses, and the surfaces are coated with films. The laser head for the laser processing machine utilizes cheap protective mirrors to block splash to damage the precise focusing mirror under the condition of production ensuring and minimizes loss under the condition that the splash can not be avoided.
Description
Technical field
The utility model relates to a kind of laser process equipment, particularly a kind of laser head that is used for laser machine.
Background technology
Laser processing technology is a kind of emerging process technology, and it has the efficient height, and cost is low, and pattern and flexible in batches damages advantages such as little to target material.
In laser engraving, mark, welding and the cutting processing, laser head is directly in the face of target workpiece, the Laser Processing utilization be that light beam focuses on the excessive temperature that the back produces, make target workpiece partial melting to be processed or gasification, surface of the work is because of fusing or gasification meeting formation smog or fine particle in the process, this smog can have influence on the transparency of laser condensing lens, the temperature of laser beam is descended, simultaneously, after descending, the focus lamp transparency very easily heats up, heat up and not only destroyed the focal length stability of focus lamp, also may cause the eyeglass breakage.
In the prior art, generally adopt the method for gas shield eyeglass.When carrying out Laser Processing; sometimes need workpiece is further applied gas; or anti-oxidation; or utilize oxidation; the method of gas shield camera lens is that gas is blown out from laser head cavity or laser head periphery; reach the original effect of gas on the one hand, also assist to dispel smog and fine particle on the one hand.But, spattered the splash that sends for workpiece melt region in the process by gas or certain pressure, the protective effect that gas can reach is also not obvious, in the actual production, the problem of splash damage focus lamp often takes place.The focus lamp of laser machine belongs to precise part, and trickle damage promptly can bring serious consequence, so, need a kind of novel laser head, focus lamp is carried out better protection, reduce loss.
The utility model content
In order to overcome the problem of in the prior art focus lamp of laser head being protected deficiency; the utility model provides a kind of laser head that is used for laser machine; various smog, fine particle and splash damage that this laser head can not produced in the production process with the cost protection focus lamp of minimum reduce loss.
The technical scheme that the utility model adopted is: comprise laser head housing and focus lamp, also comprise at least one group of protective glass, described protective glass is arranged on the light path downstream of focus lamp.
Further, described protective glass and the coaxial setting of focus lamp.
Further, described protective glass is a planar lens.
Further, described protective glass surface coating.
The beneficial effects of the utility model are: guaranteeing under the situation of producing, utilizing cheap protective glass to intercept the damage of splash to the focus lamp of precision, under the situation that can't avoid splash to produce, loss is being dropped to minimum.
Description of drawings
Below in conjunction with drawings and Examples the utility model is further described.
Accompanying drawing is the structural representation of the laser head of laser machine of the present utility model.
The specific embodiment
In the accompanying drawing, the laser head of laser machine of the present utility model comprises laser head housing 1 and focus lamp 2, also comprises protective glass 3, and protective glass 3 is provided with one group at least, is provided with one group in the present embodiment; Protective glass 3 is arranged on the light path downstream of focus lamp 2; Protective glass 3 and focus lamp 2 coaxial settings; Protective glass 3 is a planar lens.The laser head of laser machine of the present utility model has utilized 3 pairs of focus lamps 2 of protective glass to protect, and under the situation that inevitable splash produces, protective glass 3 has intercepted the damage of splash to focus lamp 2, has reduced loss.
Preferably, in order to guarantee that laser optical path do not receive protective glass influence, protective glass 3 and focus lamp 2 coaxial settings.
Preferably, in order to reduce protective glass 3 production costs, can use planar lens as protective glass 3.
Preferably, in order to improve the light transmittance of protective glass 3, can be at protective glass 3 surface coatings.
