Embodiment
For the present invention is become apparent, hereby with preferred embodiment, and coordinate accompanying drawing to be described in detail below.
Embodiment
As shown in Figure 1, for the image synchronization of freeze-drying cillin bottle lamp inspection machine is followed harvester front view, the image synchronization of described freeze-drying cillin bottle lamp inspection machine is followed harvester and is mainly comprised main shaft 1, lamp inspection dish 2, cillin bottle to be checked 3, light source 4, light source installing plate 5, industrial camera 6, industrial camera installing plate 7, pivoted arm 8, hollow direct-driven servo motor 9, hollow direct-driven servo motor output flange 10, main platform 11, jaw 12, motor mounting rack 13, reductor 14, main motor 15.
On main platform 11, be fixed with hollow direct-driven servo motor 9, main shaft 1 is located in the center pit of hollow direct-driven servo motor 9 rotationally, and main shaft 1 is rotatably installed on main platform 11 through hollow direct-driven servo motor 9, concentric with hollow direct-driven servo motor 9.Main platform 11 bottom surfaces are fixed with motor mounting rack 13, and main motor 15 is connected with reductor 14, and main motor 15 is fixed on motor mounting rack 13 with reductor 14, and reductor 14 output shafts are connected with one end of main shaft 1 by shaft coupling.The other end of main shaft 1 is located at the center of lamp inspection dish 2 and is fixedly connected with lamp inspection dish 2, and the periphery of lamp inspection dish 2 is installed a plurality of jaws 12, and as shown in Figure 2, cillin bottle 3 to be checked is clamped head by jaw 12, is suspended on before industrial camera 6 and light source 3.By regulating the height and position of lamp inspection dish 2 on main shaft 1, make cillin bottle 4 body height to be checked consistent with industrial camera 6.Hollow direct-driven servo motor output flange 10 is directly installed on hollow direct-driven servo motor 9, one end of pivoted arm 8 is mounted with light source installing plate 5, light source 4 is installed on light source installing plate 5, the other end of pivoted arm 8 is directly fixedly connected with on hollow direct-driven servo motor output flange 10 and is mounted with industrial camera installing plate 7, and industrial camera 6 is installed on industrial camera installing plate 7.In the present embodiment, industrial camera 6, light source 4 are positioned at the inner side of cillin bottle 4 to be checked, and according to actual needs, industrial camera 6, light source 4 also can move to the outside of cillin bottle 4 to be checked.
Because main shaft 1 is located in the center pit of hollow direct-driven servo motor 9, the two closely cooperates, and concentricity is easier to guarantee.In installation process, only need to adjust light source 4 and industrial camera 6 in pivoted arm 8 Shang positions, guarantee that the two and pivoted arm are on same straight line.In testing process, by controlling initial position and the speed of main motor 15 and hollow direct-driven servo motor 9, can guarantee synchronism, thereby obtain high-quality image, improve the accuracy of detection of equipment.
Concrete course of action is as follows: first according to the height dimension of cillin bottle 3 to be checked, adjust the height and position of lamp inspection dish 2, make cillin bottle 3 body height to be checked consistent with industrial camera 6.Whole detection system initialization, hollow direct-driven servo motor 9 is back to initial position, and under the driving of main motor 15, main shaft 1 drives lamp inspection dish 2 rotation to cillin bottles 3 to be checked to be positioned at before industrial camera 6, light source 4, and three is in a straight line.In testing process, main shaft 1 is all the time with uniform rotation, and lamp inspection dish 2, jaw 12, cillin bottle to be checked 3 all rotate around main shaft 1 with same angular velocity; Industrial camera 6, light source 4 start Accelerating running under the driving of hollow direct-driven servo motor 9, start equal quick-action row when speed reaches the speed of main shaft 1.Now industrial camera 6, cillin bottle to be checked 3, light source 4 are relatively static, and 6 pairs of cillin bottles 3 to be checked of industrial camera are taken pictures fast continuously, complete and detect needed image acquisition.Industrial camera 6 completes after image acquisition, and hollow direct-driven servo motor 9 returning quicklies, to initial position, carry out next round image synchronization and follow collection.Hollow direct-driven servo motor 9 output torques that the present invention adopts are large, can make light source 4, industrial camera 6 obtain compared with high acceleration returning quickly, thereby shorten sense cycle, improve the detection efficiency of complete machine.
