Specifically, Figure 11, the first eyeglass and the second eyeglass generally fusiformis laminated structure are refer to, the back side is provided with
Elongated strip shaped structure.
The beneficial effect that the string configuration at the galvanometer back side in the present embodiment can be produced is analyzed as follows：
Figure 12 a are refer to, existing galvanometer back structures are cellular or branching shape, and the mechanism of branching shape is unfavorable for heat
That measures scatters and disappears, and heat is easily assembled in the branching shape seamed edge both sides of intersection, causes air-swirl, air circulation resistance is big.
The elongate configuration that refer to the parallel interval in Figure 12 b, the present invention causes air to be flowed by strip gap, flows
Resistance is smaller during dynamic, adds air fluency, the air-swirl in eyeglass swing process is avoided completely, make its air stream
Logical resistance is smaller, it is ensured that laser galvanometer higher hunting frequency and response speed.
In the alternative of the present embodiment, more preferably：
The lens substrate of first eyeglass and the second eyeglass is made of carbofrax material, the excellent physical properties of carborundum,
Preferably, thermal deformation coefficient is small, and malformation is small, good stability of the dimension for heat-conductive characteristic.
With reference to above-described embodiment, what the present invention can reach has the beneficial effect that：
Firstth, the coaxial preview function of feux rouges：Feux rouges preview before laser index carving, smart Registration are realized by previewing module
Carve breadth and mark placement, and ensure that the power attenuation of laser index carving is zero；
Secondth, dynamic axle module uses the mounting means of the symmetrical pretension of left and right spring steel band, this effective gram of structure design
The fit clearance problem that machining accuracy error and assembly technology deficiency are caused is taken, it is ensured that the precision assembly between each part.
Because simple in construction, number of parts is few, assembling is easy, have the advantages that the response time is short, followability is good, stability is high；
3rd, amplitude modulation module is set up, when marking breadth needs adjustment, control software sends instruction, passes through stepper motor
Drive dynamic axle module to be moved in parallel along line slideway with screw rod transmission, be accurately switched to the position for meeting different marking breadths；
4th, independent water route refrigerating module need not be increased, cooling device is designed with galvanometer inner support body, utilized
Inner support body carries out quick heat radiating, it is achieved thereby that the efficient cooling of rack-mount motor and driving plate, is solved
The problem of caloric value increases when laser galvanometer works long hours；
5th, from carborundum laser galvanometer eyeglass, with rotary inertia is light, heat-conductive characteristic is good, thermal deformation coefficient is small,
The features such as malformation is small.Simultaneously new lens structure increases the air fluency of eyeglass ridge, avoids eyeglass from putting completely
Air-swirl during dynamic, makes its air circulation resistance smaller, it is ensured that laser galvanometer higher hunting frequency and response speed.
Finally it should be noted that：Various embodiments above is merely illustrative of the technical solution of the present invention, rather than its limitations；To the greatest extent
The present invention is described in detail with reference to foregoing embodiments for pipe, it will be understood by those within the art that：Its according to
The technical scheme described in foregoing embodiments can so be modified, or which part or all technical characteristic are entered
Row equivalent substitution；And these modifications or replacement, the essence of appropriate technical solution is departed from various embodiments of the present invention technology
The scope of scheme.
