Abstract
The invention discloses a photographic device for material increase manufacturing. The photographic device comprises a photographic device shell and an imaging assembly arranged in the photographic device shell. The imaging assembly comprises a lens and a sensitization chip, a filter and an air inlet are further arranged in the photographic device shell, the filter is located on the outer side of the lens, the air inlet is arranged along the circumferential direction of the photographic device shell and located in the outer side of the filter, and the outlet direction of the air inlet hole is located at the eccentric position of the center of the cross section of the photographic device shell. According to the photographic device, a layer of protection air flow is formed on the filter through the air inlet, and therefore pollution to the surface of the filter is avoided; the filter filters lasers reflected from a bath, and therefore it is guaranteed that the sensitization chip in the photographic device collects real bath morphology; and a water cooling device can effectively prevent the photographic device from being influenced by the external environment; and meanwhile, heat emitted by a control chip inside the photographic device is emitted.
Description
Technical field
The invention belongs to the material increasing field in laser technology field.It is specifically that a kind of water-cooled that carries is protected with air knife
The camera head of shield.
Background technology
Existing metal 3D printing technique mainly has metal dust 3D printing technique, metal to send according to the difference of feeding form
Silk 3D printing technique.And metal dust 3D printing technique is subdivided into powder feeding formula metal 3D printing technique and powdering formula metal 3D
Printing technique.Whether is the maturation that it is critical only that moulding process of metal 3D printing technique.And current existing metal 3D printing skill
Art is appointed to a certain extent cannot so replace some traditional high energy consumptions, the processing mode of high-risk, beat mainly due to metal 3D
Print technology not completely reason such as maturation in processing technique is caused, and is caused using the part of metal 3D printing technique molding at certain
A little special dimensions can not still substitute the part that traditional processing mode is processed.
The process engineer of metal 3D printing technique carry out technique grope, in debugging process, it is desirable to using certain equipment
Each forming process is able to record that, facilitates the later stage to carry out industrial analyses.And the building ring of existing screen collecting device on the market
The protection of border temperature, lens protection and sensitive chip does not still possess used in metal 3D printing equipment above, therefore urgent need one
Plant the camera head with cooling and lens protection to meet the requirement for recording metal 3D printing equipment forming process.
The content of the invention
The technical problem to be solved is to be directed to above-mentioned the deficiencies in the prior art, and provides a kind of with camera lens guarantor
The camera head of protective function.
To solve above-mentioned technical problem, the technical solution used in the present invention is：
A kind of camera head for increasing material manufacturing, comprising camera head housing and the imaging being arranged in camera head housing
Component, the image-forming assembly includes lens and sensitive chip, it is characterised in that：Filter is additionally provided with camera head housing
And air inlet, the filter is positioned at the outside of the lens, and the air inlet is circumferentially disposed along the camera head housing, should
Air inlet is located at the outside of the filter and the Way out of air inlet is located at the inclined of the camera head housing cross-sectional center
Heart position.
A water cooling plant is additionally provided with the lower end of the camera head housing, the water cooling plant is by with the in/out mouth of a river
Toroidal cavity composition.
The water cooling plant coordinates with camera head body clearance, and gap portion is connected by thermal conductive silicon.
The filter is coated glass.
Compared with prior art, the invention has the advantages that：
1st, the protection of an annular airflow is formed on the outside of filter by air inlet, it is to avoid filter is polluted by flue dust or dust.
Can ensure that the camera head will not hinder the biography of light because of flue dust or dust when being operated in in flue dust, the environment of dust
Broadcast and cause to shoot the unsharp phenomenon of picture.
2nd, the laser that molten bath is reflected may filter that by filter, real Pool can be collected.
3rd, by water cooling plant, can allow the device to work long hours in the higher processing environment of temperature.
Description of the drawings
Fig. 1 show the structural representation of the camera head with water-cooled and air knife protection.
Fig. 2 show the schematic diagram with air knife in water-cooled and the camera head of air knife protection.
Fig. 3 is shown with the water cooling plant schematic diagram in water-cooled and the camera head of air knife protection.
Wherein, 1 is filter, and 2 is camera head housing, and 3 is air inlet, and 4 is lens, and 5 is sensitive chip, and 6 are control core
Piece, 7 internal cavities, 8 is water cooling plant in/out mouth, and 9 is ring protection air-flow, and 10 is water cooling plant.
Specific embodiment
Below in conjunction with the accompanying drawings, the present invention is further elaborated:
As shown in Figure 1, 2, 3, a kind of camera head for increasing material manufacturing of the present invention, can extensively apply and increase material with 3D printer etc.
Manufacturing equipment, specifically includes filter 1, camera head housing 2, air inlet 3, lens 4, sensitive chip 5, control chip 6 and water
Device for cooling 10.
As shown in Fig. 2 air inlet 3 is evenly distributed on camera head housing 2, and installed in the front end of filter 1.Air knife is protected
Device is connected to inert protective gas when working by the entrance of air inlet 3, and in the front end of filter 1 annular as shown in Figure 2 is formed
Protection air-flow 9.So that the flue dust in air cannot close filter 1 with dust.
Filter 1 is arranged on the front end of lens 4, while for the laser for filtering molten bath reflection, also protects the cleaning of lens, protects
The cleannes of lens are demonstrate,proved.
Fig. 3 show water cooling plant 10, and the device is ring device, is matched somebody with somebody with the gap of camera head housing 2 in installation process
Close, gap location is connected using thermal conductive silicon.When water cooling plant 10 works, carried out into water and water outlet by water cooling plant in/out mouth 8.
Cooling circulation is internally formed in cavity 7.External environment condition high temperature can be effectively avoided to pass to inside camera head, while
The heat of internal control chip diverging can be cooled down.
