Technical field
The present invention relates to field of laser processing, more particularly to a kind of knot for laser machining mobile phone waterproof earpiece screen precise micropore
Structure and its process.
Background technology
In the prior art, in the mobile phone that we use, earpiece all machined a few row's hole arrays on the net, at present by
Bigger in the small aperture size of display, after receiver drips to water sometimes, water can be penetrated into permutation aperture inside receiver, from
And earpiece is set to break down.Therefore, it is necessary on the premise of ensureing that receiver leads acoustic performance, change array hole pore size,
The receiver of mobile phone is protected.Lot of domestic and international people uses these array holes of tool sharpening, but because material hardness is big, knife
Tool processing is rigidly limited by itself, and when processing too small hole, cutter is because stiff problem is easily broken off, and processing efficiency
Low, workpiece is yielding, it is also necessary to is often eliminated the shortcomings of replacing cutter, clamping tedious process, very flexible.Present market
The most of upper application are that array hole is processed by way of galvano-cautery, however the size in hole still can not accomplish it is more smart
Carefully, liquid medicine consumptive material is needed to use in process, the shortcomings of environmental pollution also be present, find a kind of precision is higher, practicality more
Strong processing mode by be market trend.
The content of the invention
In view of the deficienciess of the prior art, providing, one kind is easy to use, and easy to operation, stability is good, and reliability is high
Laser machine mobile phone waterproof earpiece screen precise micropore.
Realize above-mentioned purpose the technical scheme is that, it is a kind of laser machine mobile phone waterproof earpiece screen precise micropore knot
Structure, including laser polarization system, the first focusing system and the second focusing system, the left side of the laser polarization system, which is set, swashs
The light hole of radiant, the axis direction of light hole are arranged parallel to horizontal plane, the right side of the light hole of the LASER Light Source
Side position is provided with the collimator for calibration, and first focusing system is divided into the vertical lower of laser polarization system, institute
The downside that the second focusing system is divided into the first focusing system is stated, after the first focusing system and the second focusing system focus on
Laser beam narrow down to micron level, obtain the light beam of more power density and energy.
Further, first focusing system and the second focusing system include focusing lens and protection eyeglass.
Further, the protection eyeglass is installed on the front end of focusing lens, for protecting focusing lens and playing dust-proof
Effect.
Further, the focusing lens are arc-shaped structure.
Further, the focusing lens are convex lens, described by reflecting to obtain smaller focal beam spot to laser beam
Protection eyeglass is planar lens, does not produce physical action to laser beam, and laser beam is directed through.
Further, refractive direction of the laser beam Jing Guo laser polarization system changes 90 °.
Further, a kind of Laser Processing mobile phone waterproof earpiece screen precise micropore technique, comprises the following steps：
For step 1) for certain point on target object, laser launches incidence after the filtering of laser beam collimator, collimation
To laser polarization system；
Step 2) laser polarization system enters horizontal deflection to laser beam；
Laser beam vertical incidence after step 3) deflection forms focusing for the first time, swashing after focusing to the first focusing system
Light beam is again incident on the second focusing system, forms second of focusing of laser beam；
Radiating laser beams of the step 4) after double focusing to specified point on target object carries out laser treatment.
Further, the spot size for second of laser beam focused on being formed in step 3) is contracted to micron level.
Further, the tapered structure of receiver precise micropore that laser beam processing types it out, the cone point to
Outside.
Beneficial effects of the present invention：The receiver precise micropore that laser beam processing types it out is amplified using 200 times of magnifying glasses
Afterwards, the tapered structure of receiver precise micropore, cone point is outside, and receiver precise micropore precision is high, but does not influence the biography of sound
Defeated, when there is water droplet to earpiece, due to pyramidal structure reason, water is not flowed into inside mobile phone；On the other hand, by right
Laser beam carries out secondary focusing, obtains that energy density is higher, and power is stronger, finer laser beam, so as to right
Material carries out efficient, quick, fine processing, substantially increases the production efficiency of material processing, and enhances production equipment
Water resistance.
