技术领域technical field
本实用新型涉及电子束选区熔化技术领域，具体涉及一种视觉系统防污染装置。The utility model relates to the technical field of electron beam selective melting, in particular to a visual system anti-pollution device.
背景技术Background technique
电子束选区熔化技术(electron beam selective melting，英文简称EBSM)是一种采用高能高速的电子束选择性地轰击金属粉末，从而使得粉末材料熔化成型的增材制造技术，是目前新兴的一种快速制造工艺。该技术具体实施过程如下：在电子束选区熔化成型的成型腔室(具体为真空室)内，先通过铺粉装置在成型区域上均匀地逐层平铺金属粉末，并由计算机控制高能电子束或激光，根据所要成型零件的横截面参数来熔化金属粉末，达到逐层制造的目的，来实现三维零件的快速制造。Electron beam selective melting technology (EBSM for short) is an additive manufacturing technology that uses high-energy and high-speed electron beams to selectively bombard metal powder, thereby melting and forming the powder material. manufacturing process. The specific implementation process of this technology is as follows: In the forming chamber (specifically, the vacuum chamber) of electron beam selective melting and forming, the metal powder is evenly spread layer by layer on the forming area through the powder spreading device, and the high-energy electron beam is controlled by the computer. Or laser, according to the cross-sectional parameters of the parts to be formed to melt the metal powder, to achieve the purpose of layer-by-layer manufacturing, to achieve rapid manufacturing of three-dimensional parts.
传统的电子束选区熔化技术中，需要确保成型腔室为真空环境，以保证电子束正常工作。同时，为了有效地监测成型过程，一般会安装工业相机和照明灯作为视觉系统，在真空环境下来对表层进行视觉图像的采集。由于金属粉末在电子束的轰击下熔化后，内部所含的化学组分在真空环境下更容易挥发，而长时间的热加工过程使得金属挥发物会不断地对周围环境进行蒸镀，从而易出现工业相机被镀上一层膜的情况，而工业相机被污染后无法再对视觉图像进行采集。此外，熔化后的金属粉末内部所含的化学组分挥发后，也会影响所成型零件的化学组分，使其性能出现差异。In the traditional electron beam selective melting technology, it is necessary to ensure that the forming chamber is in a vacuum environment to ensure the normal operation of the electron beam. At the same time, in order to effectively monitor the molding process, industrial cameras and lights are generally installed as a vision system to collect visual images of the surface in a vacuum environment. After the metal powder is melted under the bombardment of the electron beam, the chemical components contained in the interior are more likely to volatilize in a vacuum environment, and the long-term thermal processing process makes the metal volatiles continuously vapor-deposit the surrounding environment, which is easy to evaporate. There is a situation where the industrial camera is coated with a layer of film, and the industrial camera can no longer collect visual images after being polluted. In addition, after the chemical components contained in the melted metal powder volatilize, it will also affect the chemical components of the molded parts, resulting in differences in performance.

Benchmarks, these words used to limit the direction are only for convenience of description, and do not represent limitations on the specific technical solutions of the present utility model.
参照图1和图2所示，本实用新型实施例公开了一种视觉系统防污染装置，用于防止工业相机1以及为工业相机1提供光照的照明灯2被污染，包括供气件3和连接在供气件3下方的安装件4，其中工业相机1和照明灯2设置在供气件3上方；Referring to Fig. 1 and Fig. 2, the embodiment of the utility model discloses an anti-pollution device for a vision system, which is used to prevent the industrial camera 1 and the lighting lamp 2 that provides light for the industrial camera 1 from being polluted, including an air supply part 3 and The installation part 4 connected under the air supply part 3, wherein the industrial camera 1 and the lighting lamp 2 are arranged above the air supply part 3;

本实施例中，成型室内设置有用于监测成型过程的视觉系统，视觉系统包括工业相机和照明灯，其中工业相机用于采集视觉图像，而照明灯用于为工业相机提供光照。In this embodiment, a vision system for monitoring the molding process is installed in the molding room. The vision system includes an industrial camera and a lighting lamp, wherein the industrial camera is used to collect visual images, and the lighting lamp is used to provide light for the industrial camera.
在工业相机和照明灯上设置供气件和安装件，将惰性气体从供气件的导流通道引入，并经视觉通道和光照通道进入安装件下部。整个防污染装置通过安装件安装在成型室内对应的安装部件上，从而惰性气体最终从安装件下部经成型室内的安装部件充入成型腔室内。Install gas supply parts and installation parts on industrial cameras and lighting lamps, introduce inert gas from the guide channel of the gas supply parts, and enter the lower part of the installation parts through the visual channel and light channel. The entire anti-pollution device is installed on the corresponding installation parts in the molding chamber through the installation parts, so that the inert gas is finally filled into the molding chamber from the lower part of the installation parts through the installation parts in the molding chamber.
整个结构为密封结构，将工业相机和照明灯的关键部件设置在该密封结构内，使工业相机通过视觉通道观测成型室内部，照明灯通过光照通道为工业相机提供观测所需的光照，视觉通道和光照通道的结构可以降低被金属挥发物蒸镀的概率，同时工业相机和照明灯与真空环境隔离，还可以保证这两个设备在正常环境使用。The whole structure is a sealed structure, and the key components of the industrial camera and lighting lamp are set in the sealed structure, so that the industrial camera can observe the interior of the molding chamber through the visual channel, and the lighting lamp provides the industrial camera with the light required for observation through the lighting channel, and the visual channel The structure of the light channel and the light channel can reduce the probability of being vaporized by metal volatiles. At the same time, the industrial camera and the lighting are isolated from the vacuum environment, and it can also ensure that the two devices can be used in a normal environment.
另外，成型室分别连接有进气设备和抽气设备，其中进气设备用于提供惰性气体，而抽气设备用于不断抽取成型室内的气体来保持成型室内的真空度。一般地，成型室内的气压要保证在0.15帕以下。In addition, the molding chamber is respectively connected with air intake equipment and air extraction equipment, wherein the air intake equipment is used to provide inert gas, and the air extraction equipment is used to continuously extract the gas in the molding chamber to maintain the vacuum degree in the molding chamber.

此外，在未充入惰性气体作为熔化气氛用气体时，金属粉末表面存在电子聚集，使得金属粉末颗粒之间相互排斥，成型时易产生吹粉现象，成型过程不稳定。而充入惰性气体作为熔化气氛用气体后，惰性气体会在电子束的作用下电离产生正离子，产生的正离子吸附在金属粉末上，使得金属粉末里的电子与其中和，从而正离子清除了金属粉末表面的多余电子，可防止金属粉末中的电子聚集，有效消除了金属粉末颗粒之间因大量电子存在引起的相互排斥现象，成型时不容易产生吹粉现象，成型过程稳定。In addition, when no inert gas is filled as the gas for melting atmosphere, electrons gather on the surface of the metal powder, which makes the metal powder particles repel each other, and powder blowing phenomenon is easy to occur during molding, and the molding process is unstable. After filling the inert gas as the gas for the melting atmosphere, the inert gas will be ionized under the action of the electron beam to generate positive ions, and the generated positive ions will be adsorbed on the metal powder, so that the electrons in the metal powder can be neutralized with it, thereby removing the positive ions It eliminates the excess electrons on the surface of the metal powder, prevents the accumulation of electrons in the metal powder, and effectively eliminates the mutual repulsion caused by the existence of a large number of electrons between the metal powder particles.
