Description

The closed laser

Technical field

The utility model relates to a kind of laser, particularly a kind of closed laser.

Background technology

Before the utility model was made, the control to the operational environment of laser did not technically appear in the newspapers in the laser design.If laser is installed on the production line and uses, tend to influence the performance of laser because of operational environment such as temperature, dust, humidity, vibrations etc.

The utility model content

The utility model is in order to overcome the problem of above-mentioned existence, provides that a kind of influenced by operational environment little, the closed laser.

In order to achieve the above object, the utility model has following technical scheme:

A kind of closed laser of the present utility model comprises laser, is used for the optical system that laser is exported, and the periphery of described laser is provided with airtight casing, is provided with dustproof heat-barrier material in the casing; Be provided with flexible seal ring between the light-conducting arm of described optical system and casing; Be connected with the refrigerating plant that is used to control temperature in the casing with casing; Under the optical table of laser vibration absorber is installed, vibration absorber is connected with casing.

Wherein, described refrigerating plant comprises heat exchanger, and heat exchanger is provided with the air inlet and the air outlet that communicate with casing, places the temp probe in the casing.

Wherein, described vibration absorber is the vibration absorber of rigidity such as three-dimensional, and the top of this vibration absorber is connected with the optical table of laser by screw, and the bottom of vibration absorber is connected with casing by screw.

Wherein, be provided with wind guide tank in the described casing, this wind guide tank is positioned at casing and is connected with the air inlet of heat exchanger.

Wherein, described casing is shaped as cuboid, cylinder, oval cylinder or obform body.

Wherein, described cabinet wall posts the thermal insulation and dust-proof material.

Wherein, on the described optical system light-conducting arm is arranged, this light-conducting arm is fixed on the optical table, is provided with flexible seal ring between light-conducting arm and casing.

Owing to taked above technical scheme, advantage of the present utility model is:

1. the casing of the refrigerating plant of laser work environment and heat-insulating and sealing is for laser provides a constant temperature, clean operational environment.

2. laser is installed on the optical table, and optical table is rigidly connected with the optical system of laser output, thereby laser and optical system all are installed on the same optical table, optical table is connected by vibration absorber with casing, the light-conducting arm and the casing of optical system flexibly connect, thereby the vibrations that produce on the minimizing production line make the work of laser more stable to the influence of laser.

3. increasing on the basis of very little cost, the performance of laser is improved greatly, cost performance is very high.

Embodiment

Following examples are used to illustrate the utility model and uses thereof, but are not used for limiting protection range of the present utility model.

Referring to Fig. 1, Fig. 2, a kind of closed laser of the present utility model is made up of laser, optical system, casing 4, refrigerating plant, optical gate 1, sealing ring 11, vibration absorber 9, wherein, refrigerating plant is made up of heat exchanger 2, air outlet 13, air inlet 12, temp probe 3 etc., and heat exchanger 2 communicates with casing 4 by air outlet 13, air inlet 12.Optical gate 1 is positioned at outside the casing 4.Sealing ring 11 is used for the gap of 4 of the light-conducting arm of optical system of sealed laser output and casings, keeps the two to flexibly connect; Optical system and laser all are fixed on the optical table 8.Vibration absorber 9 is the vibration absorber of rigidity such as three-dimensional, and the top of this vibration absorber 9 is connected with the optical table 8 of laser by screw, and the bottom of vibration absorber 9 is connected with casing 4 by screw.Wind guide tank 6 in the casing 4 is used to accelerate ventilate in the casing 4.

The utility model is connected in series the laser pump cavity 5 of laser, and the laser that sends penetrates laserresonator by bridge-type diaphragm frame 7 backs, and through behind the beam expanding lens of optical system, light-conducting arm, the focus lamp through optical system arrives surface of the work and process again.

In the course of work of whole laser, be accompanied by all the time the temperature control in the casing 4 at laser place.Wherein, in the time of heat exchanger 2 work, outer circulation with water as refrigerant with air coolings in the casing 4, wind is blown into from air inlet 12, by wind guide tank 6, in process wind guide tank 6, because wind guide tank 6 has air vent hole, so cold air can be covered with rapidly in the whole box body, gets back in the heat exchanger from air outlet 13 at last, finish a circulation; In cyclic process, temp probe 3 can be monitored the temperature in the casing 4 at any time, thereby by the temperature in the size control casing 4 of automatic adjustment heat exchanger 2 discharges, makes laser remain on work under the specified temp.

The utility model is controlled the temperature of the operational environment of laser the cooling realization of the air in the casing of laser place with refrigerating plant, casing 4 sealing and dustproofs, and the assurance laser safety is stably worked.

In the processing course of work of laser, because the parts of all lasers and optical system all are installed on the same optical table 8, the top of rigidity vibration absorbers 9 such as three-dimensional links to each other with optical flat 8 usefulness screws, the bottom also is to link to each other with casing 4 with screw, greatly reduce laser in when work suffered impact, vibrations, make its work more stable.
