In industrial production environment, many production fields can all use blasting craft to carry out paint removal, cleaning, table to workpiece surface Face roughing processing, prepares for workpiece refine.Blasting craft is to be made by abrasive material to impacting and cutting caused by workpiece surface With making workpiece surface obtain certain cleannes and roughness, improve the mechanical performance of workpiece surface.The field of sandblasting paint removal at present In, domestic most factories carry out paint removal processing using artificial sandblasting to workpiece surface, but accordingly, artificial mark spraying abrasive band is come very More problems, such as:Labor intensity is big, and time-consuming, and caused dust and noise on human body have injury, and caused powder in sandblasting procedures Dirt pollution of ecological environment etc..With the continuous development of mechanical automation, the exposure of artificial sandblasting drawback, factory is to high quality height The pursuit of benefit production, the artificial automatic blasting paint removal work that carries out is replaced to turn into necessarily becoming for industry development already using robot Gesture.
During robot automation's sandblasting paint removal, control machine people front end spray gun carries out paint removal processing to workpiece surface, For convenience of operating personnel's Real Time Observation spray gun sandblasting handling situations, workpiece sandblasting paint removal effect is checked, need to be matched somebody with somebody in robot front end Industrial vision camera is put, the real-time pictures of operating personnel are supplied to by industrial vision camera, operating personnel is sprayed robot Sand effect judges and sandblasting parameter is adjusted.Industrial vision camera be generally used for it is dry, dustless, without judder Environment in, when using industrial vision camera under strong dust sandblasting environment, it is necessary to design specific device to vision camera Protected and dedusting., can to prevent the sand grains and caused dust damage vision camera and camera lens that are ejected in sandblasting procedures Transparent protective shield is installed before vision camera camera lens and plays protection buffer action.In addition, to ensure industrial vision phase in sandblasting environment The normal operation of machine and the definition of field range, deduster is not only needed to use to reduce the dust concentration of integrated environment, in addition The sand grains to being easily adsorbed on protective cover and dust is also needed to carry out gas purging dedusting.
Therefore, design is a kind of is applied to automatic blasting environment, for robotic vision system, the gas of high-efficiency and low-cost Body blow device, operating personnel can be helped to observe sandblasting paint removal process by noiseless, fine definition vision camera, make conjunction The judgement of reason and corresponding parameter adjustment, improve operating efficiency and quality.
Utility model content
The purpose of this utility model is to provide the gas purging device for vision camera, to being inhaled in automatic blasting environment The particle and dust for investing robotic vision system front end are effectively removed, and realize that the purging of high efficiency high quality and low cost removes Dirt.
The technical scheme in the invention for solving the above technical problem is:A kind of gas for vision camera purges Device, including fixing device, inlet duct, air delivery device and the air jet system being sequentially connected, it is characterised in that:The fixed dress Put and be fixed in vision camera, the inlet duct is double internal thread reducing elbows, and lower section sets air inlet connectivity trachea, for leading to Enter compressed air;Spherical universal mechanism that the air delivery device includes being sequentially connected, stainless steel straight tube, straight pipe connecter and secondary Variable spherical universal mechanism is connected, the spherical universal mechanism is connected with double internal thread reducing elbows, for adjusting compressed air Airflow direction and angle simultaneously convey compressed air;The air jet system connects with the secondary variable spherical universal mechanism of connection, is used for Purged to vision camera camera lens position jet.
Further, the threaded end of the spherical universal mechanism connects with double internal thread reducing elbow outlet ports, institute Stainless steel straight tube to be stated to be connected with spherical universal mechanism rotatable end, the straight pipe connecter is connected with stainless steel straight tube, and described two The threaded end of the secondary variable spherical universal mechanism of connection is connected with straight pipe connecter.
Further, the angle rotatable of the spherical universal mechanism and the variable spherical universal mechanism of secondary connection for 0 ~ 360 °, the nut coordinated with screw thread is provided with outside it, for controlling the adjustment and fixation of angle.
Further, the air jet system is wide-angle Fan spray head.
The fixing device is fixed on above robot front-end vision system by the screw on four angles and screw hole, institute State double internal thread reducing elbows to be connected with fixing device, air inlet connectivity trachea below double internal thread reducing elbows, by external The control instruction that electrical control gear is sent can adjust the air pressure size of compressed air at any time, and will compress sky by air delivery device Gas is delivered at air jet system, and air jet system is wide-angle Fan spray head, and the gas that puff prot sprays is uniform, angled broad, punching Hit the moderate sector of power, gas flows unimpeded no blocking, and shower nozzle direction is towards in front of robotic vision system protective cover.Gas transmission fills When putting adjustment angle, the nut of artificial Song Ning spherical universals mechanism, coordinate with screw thread, carry out the adjustment and fixation of angle.
Whole device is more by the nut in artificial Song Ning spherical universals mechanism and the secondary variable spherical universal mechanism of connection The secondary airflow direction and angle for changing compressed air, forms special shape pipeline, can more accurately control airflow direction, and reduce The loss of air pressure, wide-angle sector compressed air is uniformly sprayed by shower nozzle the size particles and dust of vision front-end are carried out effectively Remove, robotic vision system continuous high-efficient is worked.
Had the beneficial effect that caused by the utility model:(1)Under strong dust robot automation sandblasting environment, this Shen is used Gas purging device please carries out dedusting to the protective cover surface before robot front-end vision camera and surrounding, forms vision system The small environment of periphery Dust Capacity, ensure that the definition of picture captured by the normal operation and vision camera of vision camera;(2)Should Gas purging device is fixed on robot front end, can realize and work asynchronously with vision system;(3)When compressed air enters pipeline When, because the spout jet internal diameter of air jet system is less than the internal diameter of inlet duct, compressed air enters air jet system by inlet duct When, it may occur that volume reduces, pressure improves, and so as to realize second-compressed and the energy storage to compressed air, reduces in main line The loss of air pressure, total compression air dosage is greatly reduced;(4)When the special spout of the device sprays compressed air, gas Stream continuously sprays in wide-angle sector high-pressure uniform, and sand grains, the dust for being adsorbed vision system protective cover front end are cleared up more thorough; (5)The regulation of multiple angle can be carried out to the device manually, the device is pointed to specific direction, so as to reach preferable dedusting effect Fruit;(6)The gas purging device is simple in construction, takes up space small, and operating efficiency is high, convenient for installation and maintenance, service life length, into This is cheap, easy to spread.
