Equipped with certain lift off, the injection couplant into water conservation cover is retained cover until filling, persistently injects couplant in detection process；
(2) start channel ultrasonic detector, all probes start to detect, and it is certain that driven wheel servo motor pushes driven wheel to generate
Pressure remains unchanged center location in ring rotary course, and driving wheel servo motor drives driving wheel uniform rotation, and then band
Rotating ring part is at the uniform velocity rotated around its own axis, and ring rotation returns to all probes while initial point for one week and completes to enclose ring one
Detection, in the detection process, all ultrasonic signals that will test of popping one's head in are sent to channel ultrasonic detector, multichannel
The ultrasonic signal received is converted to ultrasound by ultrasound measuring instrument to be swept waveform diagram and is transferred to industrial personal computer and handled；
(3) Z axis is driven to drive end face array probe to move radially distance, delta along ring to linear mould group by Y-axis servo motor
Y, moving direction are directed toward ring inner hole, and Δ y=(1-S) md, m are the quantity popped one's head in end face array probe each column, and S is to visit
The repetition coverage rate of head, d are the wafer diameter of probe, while driving probe gripper to drive inside and outside circle to servo motor by Z axis
Face array probe moves axially distance, delta z along ring, and moving direction is directed toward ring bottom, and Δ z=(1-S) nd, n is inside and outside
The quantity popped one's head in disc array probe each column, repeat step (2), until end face array probe be moved to ring inner port edge and
Until periphery array probe is moved to ring bottom, that is, complete the ultrasonic signal acquisition and record of ring.
9. the detection method of large ring multi-panel array ultrasonic automatic detection device according to claim 8, feature exist
In: in step (1), inside and outside inside and outside disc array probe and ring between disc, upper and lower end face array probe and ring upper and lower side
Lift off between face is xd；Water conservation cover is bonded with ring surface.
10. the detection method of large ring multi-panel array ultrasonic automatic detection device according to claim 8, feature exist
In: in step (2), the angular velocity of rotation of ring is 0.2~1rad/s.
