Embodiment
Below in conjunction with Figure of description the utility model is further detailed:
The utility model relates to a kind of vision detection system, and it comprises a frame, and said detection system also includes conveyer, optical image former, light source 3 and control device; Conveyer comprises guide rail 1, servomotor (not shown); Conveyer is arranged on the frame, and optical image former is arranged on the front upper place of frame, and light source 3 is oppositely arranged with optical image former; Control device is arranged on the frame; And be connected with optical image former, in the utility model, described optical image former is a digital camera.
In the utility model, described detection system also comprises a gyrator 7, and said gyrator 7 comprises body and prism; On two relative faces on the said body two holes are set, prism is arranged in the body, and the angle in the minute surface of prism and two holes is 45 °; So, the image of from a hole, injecting just can obtain in another hole through the reflection of prism; The described gyrator 7 of the utility model connects optical image former and camera lens 8, and so, the position that digital camera 4 is put just has been rotated 90 °; Thereby the width of total system is reduced, and system is more compact.
In the utility model; Said light source 3 is arranged on the support 9 with camera lens 8; Said support 9 makes it to be oppositely arranged, thereby makes shooting effect better in order to limit the putting position of camera lens 8 and light source 3; Light source 3 described in the utility model is the bilateral telecentric lights, and described camera lens 8 is a bilateral telecentric mirror head.
Said detection system has also comprised Fibre Optical Sensor 2; Fibre Optical Sensor 2 is arranged on the top of guide rail 1, and Fibre Optical Sensor 2 is arranged on the front portion of guide rail 1, and so the part that detects of desire at first passes through Fibre Optical Sensor 2 in transport process; Fibre Optical Sensor 2 is connected with control device; When part through behind the Fibre Optical Sensor 2, Fibre Optical Sensor 2 writes down its positional information, thereby is convenient to corresponding with the captured photo of later stage optical image former.
In the utility model, said control device comprises PLC5 and industrial computer 6, and PLC5 is connected through the RS232 serial port communication line with industrial computer 6.
The detection method of the said detection system of the utility model mainly comprises the steps:
1) guide rail transmits the part of desire detection through Fibre Optical Sensor;
2) positional information of Fibre Optical Sensor record part is sent to PLC;
3) guide rail continues part is sent to the digital camera place, and PLC triggered digital camera is taken pictures;
4) photo is sent to industrial computer through kilomega network, judges by industrial computer whether part is qualified.
In above-mentioned steps, because the stationkeeping of digital camera, and the putting position of part to be measured is unfixing; So the distance between part and the camera just has gap; The photograph of then shooting can not reflect the formal state of part sometimes accurately, and therefore, the utility model is provided with setting gauge and stepper motor; Setting gauge is arranged between Fibre Optical Sensor and the camera lens, and it receives step motor control.When part process setting gauge, the setting gauge action is arranged on guideway centreline with part, and so, the relative position of part just is determined, and it is more accurate to take the photograph that comes out.
